+ <s>In dieser Arbeit präsentieren wir einen neuartigen Ansatz für den systematischen Entwurf von integrierten LC Tank VCO-Schaltungen basierend auf dem An-dronov Hopf Theorem und der Störungstheorie.</s>
+ <s>Der Ansatz ermöglicht es, eine Abschätzung des resultierenden Ab-stimmbereichs, eine Stabilitätsanalyse und eine Berechnung der Amplitude des VCOs im Vorfeld des eigentlichen Entwurfs durchzuführen.</s>
+ <s>Des Weiteren erlaubt die vorgestellte Methode eine Optimierung des VCOs hinsichtlich der in den Spezifikationen geforderte Amplitude und eine Minimierung der höheren Harmonischen.</s>
+ <s>Mit Hilfe eines ladungsbasierten MOS-Modells ist es möglich die spannungsabhängige Kapazität der Varaktortransistoren durch einen analytischen Ausdruck zu beschreiben.</s>
+ <s>Auf Basis dieses analytischen Ausdrucks wird die amplitudenabhängige Großsignalkapazität des VCOs in Abhängigkeit von Designparametern und der Tuningspannung modelliert.</s>
+ <s>Die Gültigkeit der vorgestellte Entwurfsmethode wird anhand eines Beispielentwurfes eines 2.4 GHz VCO unter Verwendung einer 0.25 µm HF-CMOS Technologie verifiziert.</s>

+ <s>Durch steigende Frequenzen und immer komplexer werdende Modulationsverfahren wachsen die Anforderungen an die einzelnen Komponenten moderner HF Kommunikationssysteme.</s>
+ <s>Dies hat zur Folge, dass die Spezifikationen die eine VCO, als einer der Basisblöcke moderner Kommunikatios-systeme, erfüllen muss immer schwerer zu realisieren sind.</s>
+ <s>Im einzelnen sind dies die Realisierung der steigenden Frequenzen, ein großer Abstimmbereich aufgrund der steigenden Verbreitung von Breitbandapplikationen, eine niedrige Leistungsaufnahme und geringes Phasenrauschen.</s>
+ <s>Des Weiteren muss der VCO hinsichtlich einer maximalen Amplitude optimiert werden, um die nachfolgende Mischerstufe zu treiben.</s>
+ <s>Bei dem Entwurfsprozess von integrierten Oszillatorschaltungen handelt es sich um eine sehr komplexe Aufgabe, die stark erfahrungsbasiert ist.</s>
+ <s>Deshalb wird ein systematischer Entwurfsprozess benötigt, der es ermöglicht vor der eigentlichen Schaltungssimulation mit einem Schaltungssimulator eine Abschätzung aller Designparameter durchzuführen.</s>
+ <s>Basierend auf vorausgegangenen Arbeiten zur nichtlinearen Modellierung von Oszillatorschaltungen mit Hilfe des Andronov-Hopf Theorems (Mathis, 2005; präsentieren wir in dieser Arbeit einen neuartigen Ansatz für einen systematischen nichtlinearen Entwurfsprozess für spannungsgesteuerte Oszillatorschaltungen.</s>
+ <s>Zur exakten Modellierung der sich im VCO einstellenden effektiven Grosssignalkapazität wurden in der Vergangenheit mehrere Ansätze veröffentlicht (Tie- Unser Ansatz ermöglicht es auf Basis des ladungsbasierten EKV MOS-Modells die spannungsabhängige Kapazität eines MOS-Transistors in schwacher und starker Inversion zu beschreiben.</s>
+ <s>Mit diesem Modell ist es möglich eine Abschätzung der Varaktorabmessungen durchzuführen und den Abstimmbereich des VCOs im Vorfeld des Designs zu simulieren.</s>
+ <s>Auf Basis dieses Kapazitätsmodells und der nichtlinearen Modellierung der einzelnen Schaltungskomponenten ist es möglich den VCO durch ein Differentialgleichungssystem zweiter Ordnung zu beschreiben, dass nur noch von Prozesspa-rametern und Designparametern abhängig ist.</s>
+ <s>Mit Hilfe der Andronov-Hopf Bifurkationsanalyse wird das entstandene nichtlineare dynamische System auf die Existenz eines stabilen Grenzzykluses untersucht und so die Designparameter bestimmt, für die der VCO stabil schwingt.</s>
+ <s>Mit Hilfe der Störungsrechnung ist es nun möglich, ausgehend von dem nichtlinearen dynamischen System das einen stabilen Grenz-zyklus besitzt, analytische Ausdrücke für die Frequenz und die Amplitude des VCOs herzuleiten.</s>
+ <s>Der vorgestellte Ansatz zum systematischen Entwurf von spannungsgesteuerten Oszillatorschaltungen ist generell auf alle VCO Architekturen anwendbar.</s>
+ <s>Aufgrund der hohen Verbreitung der LC Tank VCO Architektur wird der Ansatz in dieser Arbeit exemplarisch auf diese angewendet.</s>
+ <s>
+ <pb n="170"/>Die Arbeit ist folgendermaßen gegliedert.</s>
+ <s>Im zweiten Abschnitt wird ausgehend von der LC Tank VCO Architektur die nichtlineare Modellierung der einzelnen Komponenten aufgezeigt.</s>
+ <s>Der dritte Abschnitt beschäftigt sich mit dem von uns entwickelten Ansatz zur Modellierung der effektiven Grosssignalkapazität im VCO in Abhängigkeit der Tan-kamplitude.</s>
+ <s>Im vierten Abschnitt wird ausgehend von den Modellen der einzelnen Komponenten aus Abschnitt zwei ein äquivalentes Ersatzschaltbild für die VCO-Architektur eingeführt.</s>
+ <s>In Abschnitt fünf wird das nichtlineare dynamische System in Abhängigkeit der Designparameter für einen LC Tank VCO aufgestellt.</s>
+ <s>Abschnitt sechs zeigt die Anwendung der Andronov-Hopf Bifurkationsanalyse auf das nichtlineare dynamische System, gefolgt von der anschließenden Störungsrechnung, um die Amplitude und die Frequenz im Bifurkationspunkt zu bestimmen.</s>
+ <s>Abschließend wird in Abschnitt sieben ein Beispielentwurf für einen 2,4 GHz VCO auf Basis des vorgestellten Entwurfsprozesses durchgeführt und die theoretischen Ergebnisse mit Cadence Simulationsergebnissen verglichen.</s>

+ <s>Das Ziel von CoMStAR bestand darin, die Wechselwirkungen zwischen räumlichen und sozialen Strukturen zu untersuchen und dadurch ein methodisches Instrumentarium zu Verfügung stellen, das die soziale Dimension der Nachhaltigkeit in der Planung zu berücksichtigen hilft, indem es eine Bewertung der aktuellen städtebaulichen Leitbilder hinsichtlich ihrer sozialen Nachhaltigkeit ermöglicht und darüber hinaus die Entwicklung neuartiger Pla-nungskonzepte erlaubt.</s>

+ <s>Im Falle der zu untersuchenden Straßendaten sind topologische Eigenschaften des Netzwerkes ein wesentlicher Faktor, da nur diese Schlussfolgerungen über die Verbindungsmöglichkeiten, die Funktionsfähigkeit, die Ersatzwege, die 1 CoMStaR: Computer-based methods for socially sustainable urban and regional planning

+ <s>Die topologischen Eigenschaften eines Straßennetzwerkes lassen sich hervorragend mittels Graphen darstellen.</s>
+ <s>Eine Einführung in die Graphentheorie liefert u.a. Diestel (2005) und Jansen (2006).</s>
+ <s>Topologien werden graphisch mit Knoten und Kanten dargestellt, wobei die Knoten (Nodes, Vertices) durch die Kanten (Edges) miteinander verbunden werden (Abb. 1).</s>
+ <s>Graphdefinition nach Diestel (2005): Ein Graph ist ein Paar der disjunkten Mengen G = (V, E), so dass E ⊆ [V] 2 . Die Elemente von V sind die Knoten (Vertices V) von G, die Elemente von E sind die Kanten (Edges E) von G.
+ <gap instant="false"/>Bei einem Graphen (im Sinne der Graphentheorie) kommt es nicht auf die Lage der Knoten und die Form der Kanten an (Abb. 1).</s>
+ <s>Felsner (2003) führt zur Unterscheidung vom (topologischen) Graphen den geometrischen Graphen ein.</s>
+ <s>
+ <hi rend="italic">„Ein geometrischer Graph ist ein topologischer Graph dessen Kanten gradlinig sind, das heißt die Kanten sind Strecken zwischen den Endpunkten“</hi> (Felsner 2003).</s>
+ <s>Wir nutzen in unseren Programmen einen ungerichteten Graphen.</s>
+ <s>Dies bedeutet, dass die Richtung des Durchlaufs einer Kante von einem zum anderen Knoten keine Rolle spielt.</s>
+ <s>Die Datenstruktur, mit der die Graphen repräsentiert werden, wird als doppelt verkettete Kan-tenliste (Halbkantenstruktur) aufgebaut.</s>
+ <s>Bei der Halbkantenstruktur werden nicht Kanten, sondern Halbkanten gespeichert.</s>
+ <s>Halbkanten sind gerichtet; zwei zusammengehörige Halbkanten (Paar) zeigen in die entgegengesetzte Richtung und bilden eine Kante.</s>
+ <s>Jede Kante ist von genau zwei Facetten (zu jeder Halbkante gibt es eine entgegengesetzte Halbkante) umgeben (Abb. 2).</s>
+ <s>Der Vorteil der Halbkantenstruktur besteht darin, dass viele (Such)Operationen in konstanter Zeit ausgeführt werden können.</s>
+ <s>
+ <pb n="4"/>
+ <gap instant="false"/>In der von uns entworfenen Graphklasse 3 werden zusätzlich zur Topologie auch die geometrischen Verhältnisse der räumlichen Daten gespeichert, d.h. die Lage der Elemente, die von den Knoten und Kanten repräsentiert werden, ist bekannt.</s>
+ <s>Somit wird das Straßennetz in seiner Gesamtheit, d.h. mit seinen wesentlichen topologischen und geometrischen Eigenschaften, mittels der Datenstruktur der von uns entworfenen Graphklasse abgebildet.</s>
+ <s>Wir verwenden dafür die einfachste Interpretationsform, in welcher die Kreuzungspunkte der Straßen die Knoten sind, die Straßensegmente selbst die Kanten darstellen (Abb. 3 Mitte).</s>

+ <p>
+ <s>Zur Gewährleistung einer bestmöglichen Bildtiefe und -brillanz und damit hohen Qualitätsstandards werden heute im Rahmen der Herstellung flexibler Verpackungen bei Bedruckungsprozessen (Tiefdruck und Flexodruck) vorwiegend organische Lösemittel (hauptsächlich Ethylacetat und Ethanol) eingesetzt.</s>
+ <s>Diese verdampfen nach dem Farbauftrag und werden zusammen mit angesaugter Umgebungsluft als Abgas (Abluft) einer nachgeschalteten Behandlungsanlage zugeführt.</s>
+ <s>Ab Lösemittelmassenströmen von einer Tonne pro Stunde erweist es sich heute als wirtschaftlich tragfähig, die organischen Stoffe adsorptiv aus der Abluft zu entfernen, mit Wasserdampf zu desorbieren und zu kondensieren.</s>
+ <s>Nach einer – bedingt durch die hohe Wasserfracht – aufwändigen Aufarbeitung ist dann ein erneuter Einsatz möglich.</s>
+ <s>Unterhalb eines Lösemittelmassenstromes von 1 t/h ist bislang der Einsatz von sog. regenerativen thermischen Nachverbrennungsanlagen Stand der Technik, die die Lösemittel zu vorwiegend Kohlenstoffdioxid und Wasser oxidieren und damit detoxifizieren.</s>
+ <s>Ziel der Autoren ist es, ein Rückgewinnungsverfahren für Lösemittelmassenströme von weniger als 1 t/h (Massenstrombereich 0,2…0,8 t/h) zu entwickeln, das einerseits für Betriebe des Verpackungsdruckes wirtschaftlich interessant ist und andererseits den Gesamtkohlenstoffdioxidausstoß deutlich verringert.</s>
+ <s>Dabei ist zu berücksichtigen, dass die Herstellung eines Kilogramms von z. B. Ethylacetat knapp 2,9 kg CO 2 verursacht zuzüglich etwa 2 kg CO 2 bei der Oxidation in einer regenerativen thermischen Nachverbrennungsanlage, so dass im Falle einer Rückgewinnung der Lösemittel eine beträchtliche Absenkung des Kohlendioxidausstoßes zu erwarten ist.</s>
+ <s>Um eine Rückgewinnung der freigesetzten organischen Lösemittel wirtschaftlich tragfähig zu gestalten, ist eine Aufkonzentration zwingend notwendig.</s>
+ <s>Letzteres bedeutet, den hohen Abluftmengenstrom aus den Druckmaschinen mit relativ geringer Lösemittelbeladung in einem möglichst kleinen Gasmengenstrom mit hoher Beladung zu transformieren, so dass für die sich anschließende Kondensation der Lösemittel nicht zu niedrige Temperaturen und damit relativ kleine Energieeinsätze notwendig werden.</s>
+ <s>Als klassisches Aufkonzentrationsverfahren wird heute die Adsorption der Lösemittel an Aktivkohle oder Zeolithe mit anschließender Wasserdampfdesorption [1] eingesetzt.</s>
+ <s>Allerdings sind die verwendeten Lösemittel teilweise in Wasser löslich, so dass
+ <pb/>sich eine aufwändige und energieintensive Aufarbeitung mit dem Ziel des Wiedereinsatzes anschließt.</s>
+ <s>Alternativ kann eine Inertgasdesorption z. B. mit Stickstoff erwogen werden.</s>
+ <s>Allerdings benötigt man hierfür Temperaturen oberhalb von ca. 200 °C, verbunden mit der Gefahr der beschleunigten Zersetzung insbesondere von Ethylacetat zu Essigsäure durch Reaktion mit dem mit der Abluft eingetragenen Wasserdampf aus der im Druckprozess angesaugten Umgebungsluft.</s>
+ <s>Auch können durch das Adsorbens (Aktivkohle, Zeolithe) katalytische Effekte wirksam werden, die den Zersetzungsvorgang begünstigen.</s>
+ <s>Die Lösemittel sind dann nicht mehr (physikalisch) rückgewinnbar.</s>
+ <s>Ein Ausweg besteht darin, anstelle eines ad- ein absorptives Aufkonzentrationsverfahren zu wählen.</s>
+ <s>Die Abluft aus den Druckprozessen wird dabei mittels einer hochsiedenden Flüssigkeit gewaschen, wobei die organischen Lösemittel gebunden werden.</s>
+ <s>Dieser Vorgang erfolgt bei niedriger Temperatur (z. B. 20 °C).</s>
+ <s>Die Desorption wird beispielsweise mit Stickstoff bei höherer Temperatur bis etwa 130 °C durchgeführt, so dass ein mit Lösemitteln hochaufkonzentrierter Gasstrom entsteht, der in eine Kondensation gelangt, so dass die Lösemittel in die flüssige Phase übergehen und nach einer einfachen Destillation und/oder Membrantrocknung wieder verwendet werden können.</s>
+ <s>Da das Desorptionstemperaturniveau relativ zur Adsorption niedriger ist und katalytische Effekte im Hochsieder nicht zu besorgen sind, wird die Essigsäurebildung aus Ethylacetat stark unterdrückt.</s>
+ <s>Allerdings ist der beschriebene Rückgewinnungsprozess bislang nicht für die vorgesehene Anwendung entwickelt, so dass hieraus Forschungs-und Entwicklungspotenzial erwächst.</s>

+ <s>2 Stand der Technik: Die regenerative thermische Oxidation (RTO) </s>
+ </head>
+ <p>
+ <s>Bild 1 zeigt die Einbindung einer regenerativen thermischen Oxidationsanlage in das Abluft- und Wärmenetz einer Druckerei, die flexible Verpackungen herstellt [2]. Emittenten, d. h. lösemittelhaltige Abluftmengenströme verursachende Produktionsanlagen, stellen zwei sog. Flexodruckmaschinen, eine Tiefdruckmaschine sowie eine Waschmaschine (für Druckwalzen etc.) dar, die in eine Sammelleitung einspeisen.</s>
+ <s>(Für den Fall, dass die Abluftreinigungsanlage ausfällt, besteht aus sicherheitstechnischen Erwägungen die Möglichkeit der Abgabe der Abluft über einen Bypass.) Der gesammelte Abluftmengenstrom gelangt schließlich in die RTO-Anlage, die aus einem Umschaltklappensystem (1), den Regeneratoren A, B, C und dem darüber liegenden Brennraum (2) besteht.</s>
+ <s>Ein Brenner (3) heizt das Gesamtsystem auf.</s>
+ <s>Die Regeneratoren (Speicherbetten für Wärme) werden zyklisch umgeschaltet.</s>
+ <s>Ein Regenerator wärmt die Abluft vor (Regenerator A), einer kühlt das gereinigte Gas bzw. Reingas (Regene-
+ <pb/>rator C) und ein Regenerator (Regenerator B) wird gespült, damit vor dem Umschalten von Abluft auf Reingas keine ungereinigten Bestandteile in das Reingas gelangen.</s>
+ <s>Die Regeneratortechnik ermöglicht eine sehr hohe Vorwärmung der lösemittelhaltigen Abluft, so dass schon relativ geringe Lösemittelmassenströme ausreichen, eine Fahrweise ohne zusätzlichen Brennstoff zu ermöglichen (sog. autothermer Betrieb).</s>
+ <s>Bei höheren Lösemittelfrachten kann ein Reingasteilstrom aus der Brennkammer ausgekoppelt werden (6), so dass Wärmeträger (Thermalöl (7) und Wasser (8)) zur Beheizung der Produktion bereitgestellt werden können.</s>
+ <s>Wird darüber hinaus Produktionswärme benötigt, stehen sog. direkt befeuerte Wärmeerzeuger (10, 11) bereit, die zusätzlich Heizwärme einkoppeln können.</s>
+ <s>
+ <gap instant="false"/>Tabelle 1 vermittelt einen Eindruck zu den benötigten Einsatzstoffen und energien, den Betriebsmittelkosten sowie den Kohlendioxid-Äquivalenten einer RTO-Anlage für einen Abluftmengenstrom von 60.000 m n 3 /h.</s>
+ <s>Es wird deutlich, dass der insgesamt erzeugte CO 2 -Massenstrom doch beträchtliche Ausmaße annimmt, so dass sich die Frage stellt, wie hoch die Reduktion durch eine Lösemittelrückgewinnung ausfällt.</s>
+ <s>Aus Sicht eines produzierenden Unternehmens ist natürlich gleichermaßen zu ermitteln, inwiefern ein relevanter wirtschaftlicher Vorteil erzielbar ist.</s>

+ <s>3 Der neue Technologieansatz: Lösemittelrückgewinnung mittels Hochsiederwäsche und Desorbatkondensation </s>
+ </head>
+ <p>
+ <s>Den neuen Technologieansatz gibt Bild 2 wieder, wobei die Wärmeerzeugung für die Produktion separat erfolgen muss.</s>
+ <s>
+ <gap instant="false"/>
+ <pb/>Das Schema in Bild 2 entspricht dem derzeitigen Stand bei der Verfahrensentwicklung, die vorgesehene Gasturbine zur Bereitstellung elektrischer Energie sowie Prozesswärme zur Beheizung des Absorbates (Wärmeübertrager oberhalb der Desorptionskolonne (6), Einkopplung von Wärme W) wurde der Übersichtlichkeit halber nicht dargestellt.</s>
+ <s>Gleiches gilt für die Lösemittelaufbereitung (LMA).</s>
+ <s>Der neue Verfahrensansatz ist zunächst gekennzeichnet durch eine Abgaskühlung, zumal sich die Aufnahmefähigkeit des Absorbens (hier: Genosorb 1843 3 )bei sinkender Temperatur signifikant verbessert [5]. Es folgt eine neunstufige Wäsche (Wäscher 1 bis 3) und ein Demister (4).</s>
+ <s>Die Zahl der Waschstufen resultiert aus einem F&E-Projekt [5], das durch die Deutsche Bundesstiftung Umwelt gefördert wurde.</s>
+ <s>Im Rahmen dieses Projektes ist eine effiziente Waschstufe bzw. ein Absorber für Abluftbeladungen mit Lösemitteln bis zu etwa 8 g/m n ³, wie sie im Bereich des Flexo- bzw. Tiefdruckes auftreten, entwickelt und erprobt worden.</s>
+ <s>Aus verfahrenstechnischer Sicht sind zwei Randbedingungen bedeutsam, die die Konzeption der Absorptions- bzw. Waschstufe bestimmen: 1. Durch die Zerstäubung des Absorbens soll eine möglichst große Oberfläche erzeugt werden, damit ein hoher Stoffstrom an Lösemitteln übertragen werden kann.</s>
+ <s>2. Das erzeugte Tröpfchengrößenspektrum darf nicht soweit in den Feinstpartikelbereich hineinreichen, dass ein relevanter Absorbensmassenstrom im Reingas verbleibt.</s>
+ <s>Einerseits entsteht dadurch eine zusätzliche, unerwünschte Emission, anderseits verringert der Absorbensverlust die wirtschaftliche Tragfähigkeit des Verfahrensansatzes, zumal das hier verwendete Absorbens Kosten in Höhe von ca. 15 € pro Liter verursacht [5]. Es wurde daher eine Druckzerstäubung, d.h. eine Zerstäubung ohne Sekundärmedium, gewählt.</s>
+ <s>Weiter sollte eine Trägheitsabscheidung der mit dem abströmenden Gasstrom mitgerissenen Partikel im Demister (Pos. 4 in Bild 2) realisiert werden.</s>
+ <s>Hierzu ist i. d. R. eine Beschleunigung des Gases aus der Wäscherstufe (hier auf ca. 10 m/s) notwendig, so dass die Tröpfchen bei Umlenkung nicht mehr der Strömung folgen können und abgeschieden werden.</s>
+ <s>3 Produkt der Fa. Clariant
+ <pb/>Um eine möglichst hohe Aufkonzentration des Absorbens erzielen zu können, ist eine Gegenstromführung von Abluft und Absorbens realisiert worden.</s>
+ <s>Das Ergebnis dieser Überlegungen zeigt die in Bild 3 dargestellte Prinzipskizze des Absorbers.</s>
+ <s>Auch konnte der Absorber relativ einfach charakterisiert werden, indem für den Stoffübergang im stationären Fall die Beziehung 𝑚̇ 𝐿𝑀 = 𝛽 ∙ 𝐴 ∙ 𝛥𝑋 𝑚 , Gl. 1 mit 𝑚̇: Massenstrom 𝛽: Stoffübergangskoeffizient 𝐴: stoffübertragende Fläche 𝑋: Lösemittelkonzentration im Absorbens Index LM: Lösemittel (organisch) Index m: mittlere angesetzt wurde, wobei die Größe „ 𝛽 ∙ 𝐴“ Gl. 2 eine Konstante darstellt und durch Experimente ermittelt wurde.</s>
+ <s>In Analogie zur Wärmeübertragung lässt sich eine mittlere Konzentrationsdifferenz mit 𝛥𝑋 𝑚 = 𝛥𝑋 𝑔𝑟𝑜ß −𝛥𝑋 𝑘𝑙𝑒𝑖𝑛 𝑙𝑛(𝛥𝑋𝑔𝑟𝑜ß 𝛥𝑋𝑘𝑙𝑒𝑖𝑛 )Gl. 3 berechnen.</s>
+ <s>𝛥𝑋 beschreibt jeweils (am Ein- und Austritt des Gegenstromstoffübertragers) den Abstand zum Gleichgewicht.</s>
+ <s>Hier stellt sich die Frage, wie das Gleichgewicht beschrieben werden kann.</s>
+ <s>Da zu erwarten ist, dass Genosorb 1843 im praktizierten Applikationsbereich lediglich bis etwa 10 g/L an Lösemitteln aufnimmt [5], ist von einer praktisch unendlichen Verdünnung auszugehen, so dass das Henry’sche Gesetz (mit guter Näherung) angesetzt werden kann: 𝑌 = 𝐻 ∙ 𝑋 Gl. 4 mit 𝐻: Henry-Koeffizient 𝑌: Lösemittelkonzentration im Abgas (in der Abluft)
+ <pb/>
+ <gap instant="false"/>Unter Verwendung der v. g. Beziehung konnte ermittelt werden, dass durch die in Bild 2 skizzierte neunstufige Wäsche und ausreichend geringer Lösemittelkonzentration im regenerierten Absorbens ein Lösemittelabscheidegrad beispielsweise für Ethylacetat von = 99,6 % erreicht und ein Emissionsgrenzwert von 50 mg/m n ³ an organisch gebundenem Kohlenstoff deutlich unterschritten werden kann.</s>
+ <s>Während die Prozesstechnik der Absorption auch für die Abluftbeladungen des Verpackungsdruckes nunmehr weitgehend untersucht ist, stehen in Zukunft die Seite der Desorption und insbesondere die Lösemittelkondensation im Vordergrund, wozu ein separates Forschungsvorhaben geplant wird.</s>
+ <s>Gleichwohl wurde eine Abschätzung des Aufwandes für die Schritte der Inertgasdesorption, der mehrstufigen Kondensation sowie der Lösemittelaufarbeitung (insbesondere Destillation) auf der Basis von Erfahrungswerten in anderen Branchen des industriellen Kooperationspartners AWS Group, Heilbronn vorgenommen.</s>
+ <s>Der zugehörige verfahrenstechnische Ansatz ist im bereits zitierten Bild 2 dargestellt.</s>
+ <s>Das Absorbat wird in einem Pufferbehälter (7) gesammelt, anschließend aufgeheizt und in einer Desorptionskolonne (6) im Gegenstrom zum Desorptionsfluid „Inertgas“ (Stickstoff) geführt.</s>
+ <s>Das Desorbat gelangt in eine dreistufige Kondensationsstrecke (Stufen I bis III).</s>
+ <s>Zunächst gilt es, das im Desorbat befindliche Genosorb für den Absorptionskreislauf zurückzugewinnen.</s>
+ <s>Hierfür reicht ein Temperaturniveau von ca. 50 °C (Stufe I) aus.</s>
+ <s>Anschließend wird der größte Teil des vom Absorbens aus der Umgebungsluft aufgenommenen Wassers (mit geringen Lösemittelanteilen) bis etwa 2 °C (Stufe II) abgeschieden.</s>
+ <s>Schließlich erfolgt die Kon-
+ <pb/>densation der organischen Lösemittel bei Temperaturen von weniger als - 40 °C.</s>
+ <s>Die Fraktionen aus den Stufen II und III gelangen in die bereits benannte Lösemittelaufarbeitung, woraus das Recyclat resultiert.</s>
+ <s>Dies soll zur Einstellung der Viskosität der angelieferten Druckfarben dienen und damit den Lösemittelkreislauf schließen.</s>
+ <s>Tabelle 2 vermittelt eine Übersicht zu den erwarteten Stoff- und Energieströmen, den Betriebsmittelkosten sowie den Kohlenstoffdioxidäquivalenten.</s>
+ <s>
+ <gap instant="false"/>
+ <pb/>Es wird deutlich, dass sich im Vergleich zum konventionellen Abluftverbrennungssystem deutliche Betriebsmittelkosteneinsparungen ergeben (knapp 169 €/h), die eine Amortisation einer Lösemittelrückgewinnungsanlage (einschließlich Wartung etc.) zwischen 3 und 4 Jahren (bei 6.000 Betriebsstunden pro Jahr) erwarten lassen, sofern eine Verbrennungsanlage ersetzt werden soll.</s>
+ <s>Müsste ohnehin eine Abluftreinigungsanlage neu implementiert werden, würde sich die Differenzinvestition in 2 bis 3 Jahren rechnen.</s>
+ <s>Darüber hinaus ist davon auszugehen, dass sich die Kohlenstoffdioxidemissionen durch Lösemittelrückgewinnung um (40 bis 50) % verringern.</s>

+ <s>4 Fazit </s>
+ </head>
+ <p>
+ <s>Ein Vergleich zwischen der konventionellen Technologie der regenerativen thermischen Oxidation für lösemittelhaltige Abluftströme im Verpackungsdruck mit dem neuen Technologieansatz einer Aufkonzentration mittels Hochsiedern hat ergeben, dass auch bei Lösemittelmassenströmen deutlich unter einer Tonne je Stunde ein wirtschaftlich tragfähiges Konzept möglich ist (Amortisationszeit 2 bis 4 Jahre) die Gesamtkohlenstoffdioxidemissionen in erheblichem Umfang gesenkt werden können (40 bis 50) %.</s>
+ <s>Somit lohnt die Weiterentwicklung des neuen Technologieansatzes bis zur technischen Reife.</s>

+ <s>Die durch den Skeptizismus aufgeworfenen Probleme können also nicht allein dadurch gelöst werden, dass Philosophen ihnen gründlich genug nachgehen.</s>

+ <s>Auf diesen Verlust durch Verunsicherung folgt der Verwurf der unzulänglichen Welt als unheimlich oder unbillig.</s>
+ <s>Die Reaktionen auf diese Verlustgefühle lassen sich drei (einander möglicherweise überschneidenden) Typen zuweisen, die jeweils eigenen Erscheinungsformen angehören, abhängig von dem Feld, auf dem sie auftreten (Philosophie, Literatur, Musik, Politik, Gesellschaft, Religion etc.).</s>

+ <p rend="firstLineIndent">
+ <s>Die unverkennbarste Reaktion bezeichnet Cavell schlicht als den Zweifel, der die Welt durch seine Insistenz auf Reinheit oder Strenge des Denkens zerstört.</s>
+ <s>Diese Strenge ist Teil des Versuches, endgültig festzustellen, was menschliche Subjekte wissen oder nicht wissen können.</s>
+ <s>(Man denke hier etwa an Descartes‟ Zweifel an der Eindeutigkeit seiner Sinne in den
+ <title rend="italic">Meditationen</title>.)

+ <s>Durch diese Eitelkeit unterscheidet sich die Zweifelreaktion von dem zweiten möglichen Reaktionstypus, der Resignation beziehungsweise Ergebenheit in unser Schicksal als Unwissende und die damit einhergehende Aufgabe des ohnehin unerfüllbaren Wunsches, Wissen zu besitzen.</s>
+ <s>(Cavell versteht die Metaphysik in ihren hermetischsten Momenten als eine solche Resignation, die alltägliches Wissen ignoriere und sich mit einem vagen Jenseits beschäftige.</s>
+ <s>Ich füge dem Cavells nicht explizit formulierten Gedanken hinzu, dass eine solche Resignation sich auch in Form einer Verweigerung an der Teilnahme am öffentlichen Leben und einem Rückzug ins Private ausdrücken kann.) Zuletzt besteht noch die Möglichkeit anzuerkennen, dass es zum menschlichen Wesen gehört, nach Wissen zu streben, welches nicht zu erlangen ist.</s>
+ <s>Dieses Verlangen ist für Wesen, die sich ihres Selbst bewusst – also menschlich – sind, ebenso symptomatisch wie unvermeidlich.</s>
+ <s>Die Anerkennung der Unmöglichkeit der Realisierung dieses Verlangens führt zur Auseinandersetzung mit jener sich selbst überfragenden Subjektivität und den Grundfiguren ihrer Denkweise.</s>
+ <s>Diese dritte Reaktion ist es, die nach Cavell

+ <gap instant="false"/> Die Form des Gedichts ist so traditionell, dass sie beinahe hinter sich selbst zurücktritt: 3 Strophen, je 4 Zeilen, A/B/A/B-Reimschema.</s>
+ <s>Ein Gedanke wird in der ersten Zeile eingeführt und dann im Laufe des Gedichts bekräftigt und entwickelt.</s>
+ <s>Anders als man erwarten könnte, ist es nicht das lyrische Ich, das die Welt, sondern die Welt, die das lyrische Ich verloren hat.</s>
+ <s>Das lyrische Ich postuliert die Gedanken eines anderen Agenten (hier: der Welt) und macht sich in der dritten Zeile der ersten Strophe sogar zum indirekten Objekt (
+ <quote>„von mir“</quote>).</s>
+ <s>Seine grammatikalische Unterlegenheit wiederholt sich in den letzten zwei Zeilen der zweiten Strophe in der Bestätigung seiner Anfangsbehauptung: Die Welt kann mit Recht meinen, es sei gestorben, weil es tatsächlich der Welt, vielmehr dem Weltgetümmel gestorben ist.</s>
+ <s>Erst in der vorletzten Zeile des Gedichts tritt Leben als Kontrapunkt zu diesem der Welt-Gestorbensein auf: Aber selbst dabei wird das Leben des lyrischen Ichs
+ <quote>„allein in seinem Himmel“</quote> mit dem Ruhen auf dem Friedhof verglichen (
+ <quote>„ich […] ruh‟ in einem stillen Gebiet!“</quote>).</s>
+ <s>Zwar wird die Idee des „Lebens“ in den letzten beiden Zeilen ausgeweitet, aber nicht auf eine Teilnahme am
+ <quote>„Weltgetümmel“</quote>, sondern nur auf die Liebe und das Dichten des lyrischen Ichs.</s>
+ <s>Die Vehemenz der Weltverweigerung (und die dazugehörige Verwerfung der in der Welt verbrachten Zeit) wird lesbar als Symptom der tiefgreifenden Welt-Enttäuschung – die Cavell als skeptisch bezeichnet.</s>

+ <s>Die Vertreter der Konkreten Poesie, die sich als Gruppe auffassten, haben ihre Ziele selbst ausführlich thematisiert.</s>
+ <s>So hat etwa Eugen Gomringer in einer Reihe von Texten

+ <s>Dichtung hat nach Gomringer eine gesellschaftliche Funktion zu erfüllen (so heißt es auch 1960 in
+

+ 30f.</s>
+ <s>), weswegen das Gedicht
+ <quote>„überschaubar“</quote> werden muss.</s>
+ <s>Die gesellschaftliche Funktion der Dichtung bestehe vor allem darin, einen vom Dichter gesetzten oder determinierten Spielraum zu erschließen: Damit soll der Dichter (beziehungsweise das Gedicht) den Lesern beibringen, wie man solche Spielräume sehen oder sogar erschaffen kann.</s>
+ <s>So wird der Dichter ein wichtiger Lehrer der Gesellschaftsmitglieder, denn
+ <quote>„dem wissen um die möglichkeiten des spiels kommt heute die gleiche bedeutung zu wie ehedem der kenntnis klassischer dichtersatzungen“</quote>(
+ <title>„zeitcharakter der sprache“</title>
+ 16).</s>
+ <s>Die Fähigkeit, sich mit den Möglichkeiten des Spiels zurechtzufinden, bringt Dichtung in Kontakt mit der Fähigkeit des Inder-Welt-Navigierens, im buchstäblichen Sinne.</s>
+ <s>Denn die poetische Reduktion der Sprache im neuen Gedicht, für die Gomringer plädiert, soll
+ <quote>„größere beweglichkeit und freiheit der mitteilung, die zu dem so allgemein wie möglich sein sollte [erzeugen], so wie es anweisungen auf flughäfen oder strassenverkehrzeichnungen sind“</quote>(
+ <title>„das gedicht als gebrauchsgegenstand“</title>

+ <s>Das Urteil der historischen Reiseforschung fällt dementsprechend kritisch aus.</s>
+ <s>Beatrix Langner etwa, die Verfasserin der jüngsten und fundiertesten Chamisso-Biografie, bezeichnet die Expedition als
+ <quote>„eine der merkwürdigsten Entdeckungsreisen des 19. Jahrhunderts … Ihr Vorwand fadenscheinig, ihr Kurs eine krumme Linie aus Lügen, Kompromissen und Missverständnissen, ein Täuschungsmanöver für die Öffentlichkeit“

+ </p>
+ <p rend="firstLineIndent">
+ <s>Was macht diese so ambivalente Reise nun für eine philologisch
+ <hi rend="italic">und</hi> kulturwissenschaftlich ausgerichtete Literaturwissenschaft interessant?</s>
+ <s>Und inwieweit lässt sich der Begriff der Schwelle als Metapher und Denkfigur ins Feld führen, um die Materialien der Weltumsegelung in Text, Bild und Artefakt auszuwerten?</s>
+ <s>Beides lässt sich hier nur knapp umreißen.</s>
+ <s>Der Weg zu einer ersten Antwort eröffnet sich über eine Passage zu Beginn des dritten Abschnitts von Chamissos literarischer Reisebeschreibung.</s>
+ <s>In dieser Textstelle gebraucht der Autor selbst den Begriff der Schwelle, um seiner, wie es im Titel des Kapitels heißt,
+ <quote>„Vorfreude“</quote> über die bevorstehende Ausfahrt Ausdruck zu verleihen.</s>
+ <s>Chamisso schreibt:
+ <gap instant="false"/>
+ <pb n="122"/>Chamisso schreibt diese Zeilen 1836, nur zwei Jahre vor seinem Tod und ganze zwei Dekaden nach der drei Jahre währenden Weltumsegelung.</s>
+ <s>Verortungen wie
+ <quote>„an der Schwelle“</quote> spielen dabei hier wie in seinem schriftstellerischen Werk allgemein eine wichtige Rolle.</s>
+ <s>Um den zentralen Stellenwert der Reise für den Autobiografen zu pointieren, setzt der Textausschnitt gleich mehrere Arten von Übergangsmotiven miteinander in Beziehung: Sozialisationsgeschichtlich die Entwicklung vom Kindheits- zum Erwachsenenalter beziehungsweise von Ledig- zum Verheiratetsein, mental-psychisch das Umschlagen vom Traum- in den Wachzustand, textgenealogisch den Schritt von der fiktionalen Komposition einer Weltreise in der märchenhaften Erzählung von Peter Schlemihl zur faktualen Realisation in der Teilnahme an der empirischen Forschungsexpedition, literarisch-formal die Dichotomie von Poesie und Prosa, ja sogar pekuniär das Gegensatzpaar von Geldgewinn und Geldverlust.</s>
+ <s>Im Anschluss an diese Kontraästhetik thematisiert der letzte Satz des Zitats bereits das Territorium, das sich dem Protagonisten hinter der Schwelle eröffnet: Die Zuwendung zur
+ <quote>„offenen Welt“</quote>, verbunden mit der Emphase eines wissenschaftlichen Zugriffs auf die
+ <quote>„geliebte Natur“</quote>.</s>
+ <s>Latent, aber bereits auffällig, artikuliert der Beginn des dritten Reisekapitels einen weiteren bedeutenden Motivstrang: Die Bewegung von
+ <quote>„überschwänglicher“</quote> Verheißung zu
+ <quote>„gemeiner“</quote> Verwirklichung in der Vita des Reisenden.</s>
+ <s>Diese Textelemente rund um die Figur der
+ <quote>„Schwelle“</quote> ergeben alles in allem bereits wichtige Bausteine für Chamissos Selbststilisierung in literarischer Form, für die seine Reisebeschreibung den maßgeblichen Textzeugen abgibt.</s>
+ <s>Um die Charakteristika dieser Inszenierung der eigenen Identität als Autor, Erzähler und Figur im Text möglichst präzise zu fassen, bietet sich ein Rückgriff auf das Instrumentarium an, welches die philologische Forschung für die Analyse von autobiografischen und nichtfiktionalen Gattungen der Literatur entwickelt hat (vgl. dazu einführend
+ Wagner-Egelhaaf
+ ).</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Der Reihe nach.</s>
+ <s>Ehe Chamisso mit der Darstellung seiner Reiseerlebnisse in chronologischer Abfolge beginnt, geht er in zwei Abschnitten auf die Programmatik seines Berichts ein.</s>
+ <s>Im ersten Kapitel
+ <hi rend="italic">Vorwortlich</hi> erläutert er seine Beweggründe für die Niederschrift des Reiseberichts, den Fokus und die Situation seines Schreibens; im zweiten Kapitel
+ <hi rend="italic">Einleitend</hi> liefert er einen kurzen Abriss seines Lebenslaufes von seiner Herkunft und Geburt an bis zum Zeitpunkt seiner Bewerbung für die
+ <hi rend="italic">Rurik</hi>-Expedition.</s>
+ <s>In beiden Textabschnit-
+ <pb break="no" n="123"/>ten hält sich der schreibende Reisende an Konventionen, die ihm sein Genre vorgibt.</s>
+ <s>Gleich mit seinen ersten Worten beteuert Chamisso die Wahrheit und Wahrhaftigkeit, die Authentizität und Aufrichtigkeit seiner Zeilen.</s>
+ <s>Ist die offizielle Dokumentation der Reise von 1821 in seinem Urteil noch entstellt von
+ <quote>„Errata“, „unzähligen sinnzerstörenden Druckfehlern“, „Verfälschungen“</quote> und
+ <quote>„Unverständlichkeiten“</quote> sowie überschattet von den historischen Wirren nach der Ermordung August von Kotzebues im Jahre 1819, so liefert sein Text nun das, was
+ <quote>„ein gradsinniger Mann, der selbst gesehen und geforscht, in der Kürze aufgezeichnet hat“</quote>, und diese Arbeit, so Chamisso,
+ <quote>„verdient doch wohl, in dem Archive der Wissenschaft niedergelegt zu werden“</quote>(
+ <title rend="italic">Reise um die Welt</title>
+ 83f.). Mit seiner Betonung der Autopsie, des Selbst-Erlebten und Selbst-Niedergeschriebenen seiner Reiseeindrücke, verwendet Chamisso einen weiteren lang etablierten Topos der Gattung.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Einen anderen Anspruch aber weist er weit von sich.</s>
+ <s>Anders als Autoren auf ähnlichen Expeditionen möchte er in seiner Erzählung keine Synthese zwischen wissenschaftlichen und literarischen Schreibweisen wagen.</s>
+ <s>Chamisso formuliert seine Ablehnung in Form eines Ratschlags an Freunde:
+ <gap instant="false"/> In Chamissos Textpraxis findet sich diese angestrebte Zweiteilung realisiert, wenn auch in umgekehrter Folge: Seine
+ <title rend="italic">Bemerkungen und Ansichten</title> von 1821 bilden den dritten Teil der offiziellen, wissenschaftlichen Auswertung der Reise, während der mit dem Titel
+ <title rend="italic">Tagebuch</title> überschriebene literarische Reisebericht erst 15 Jahre später erscheint.</s>
+ <s>Ob Chamisso die anvisierte Zweiteilung zwischen Literatur und Wissenschaft tatsächlich durchhält, bleibt fragwürdig.</s>
+ <s>Mit der annoncierten schärferen Abgrenzung beider Bereiche bewegt er sich jedenfalls im breiten Konsens mit dem Gattungsspektrum, das sich im Verlauf des 19. Jahrhunderts immer weiter ausdifferenziert.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Gegen Ende des ersten und mit Beginn des zweiten Kapitels entfaltet Chamisso außerdem zwei Motivstränge, welche seinen Reisebericht weniger in Richtung der Theorie und Geschichte der Reiseliteratur typisieren als ihn
+ <pb n="124"/>vielmehr auf seine außergewöhnliche Biografie hin individualisieren.</s>
+ <s>Als Erstes hebt Chamisso in der Modellierung seiner eigenen Person an mehreren Stellen die
+ <quote>„Macht der Zeit“</quote> gegenüber dem Einzelnen hervor.</s>
+ <s>In einer Epoche zwischen Revolution und Restauration, Reform und Repression, nicht enden wollenden Kriegen und aufziehenden Nationalismen entwirft Chamisso sich selbst in der lebensweltlichen Skizze seines Reiseberichts als eine von Schicksal, Fortuna und Zufall nach allen Richtungen geschleuderte Autor-Persona.</s>
+ <s>
+ <quote>„Nach manchen Irrfahrten … und nach manchem erduldeten Elend ward meine Familie zuletzt nach Preußen verschlagen“ </quote>(
+ <title rend="italic">Reise um die Welt</title>
+ 86), heißt es darin, oder an einer anderen Stelle:
+ <quote>„Irr an mir selber, ohne Stand und Geschäft, gebeugt, zerknickt, verbrachte ich in Berlin die düstere Zeit“
+ <ref>(87)</ref>
+ </quote>.</s>
+ <s>
+ <gap instant="false"/> Auch Chamissos bekannteste literarische Figur, Peter Schlemihl, gerät bekanntlich in eine ähnlich solitäre Lage: Von der Gesellschaft aufgrund seiner Schattenlosigkeit geächtet, flüchtet er sich in eine abgeschottete Existenz als Naturforscher.</s>
+ <s>Fern von jedweden menschlichen Beziehungen nimmt er schließlich seinen Wohnsitz in der Felswüste bei Theben, in deren Höhlen sich christliche Eremiten schon viele Jahrhunderte vor ihm ansiedelten.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Zur Schwelle der Einsamkeit tritt als zweites zentrales Moment der Autobiografie die Schwelle des Lebensabends.</s>
+ <s>Nicht von ungefähr beendet Chamisso seine Vorrede mit dem Hinweis auf den eigenen physischen und psychischen Verfall:
+ <gap instant="false"/>
+ <pb n="125"/>Was für die biografische Zeit dieser Niederschrift medizinisch belegbar ist, bildet gleichzeitig einen der Endpunkte in einer langen und erstaunlich früh begonnenen Kette von Selbstzuschreibungen des Alterungsprozesses: Sobald Chamisso mit seiner Hinwendung zur Naturwissenschaft die Richtung in seiner Biografie einschlägt, der er bis zu seinem Lebensende treu bleiben wird, häufen sich die Rekurse auf den vermeintlichen Greisenstatus in seinen Schriften.</s>
+ <s>Im
+ <hi rend="italic">Schlemihl</hi> treibt Chamisso die literarische Ausgestaltung des eigenen Niedergangs auf die Spitze; mit einer Passage, in der er die mit ihm namensidentische Schriftstellerfigur als Leiche auftreten lässt, umgeben von den Insignien ihrer wissenschaftlichen und künstlerischen Autorschaft: Bänden von Goethe und Haller, Humboldt und Linné, Fouqués Ritterroman
+ <title rend="italic">Der Zauberring</title>sowie einem Skelett und getrockneten Pflanzen.</s>
+ <s>Beide Hinweise, auf die Vereinsamung und das Ableben der Werk-Persona, hängen eng miteinander zusammen.</s>
+ <s>Letztendlich entkommt der
+ <quote>„allgewalt‟gen Zeit“</quote> nur, wer sich auf den allerengsten Kreis seiner selbst zurückzieht und anspruchslos dem eigenen Ende entgegenblickt (vgl.
+ von Matt
+ 177
+ ). Dass es sich dabei nicht um Abbildungen historischer Wahrheitsgehalte, sondern um Konstruktionsprinzipien autobiografischer Selbstinszenierung handelt, erhellt die philologische Perspektive – und das mit Hilfe ihres Wissens über allgemeine Gattungsregeln und autorspezifische Akzentsetzungen quer durch Chamissos belletristisches Gesamtwerk.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Chamissos Reise- und Schreibpraxis allein auf das Literarische zu beschränken hieße jedoch, seine Texte in ein zu schmales Korsett zu zwängen.</s>
+ <s>Seine Berichte über die
+ <hi rend="italic">Rurik</hi>-Expedition markieren nicht nur die Zusammenführung der bei ihm besonders starken Motive von Entwurzelung und Bejahrtheit mit Topoi von Authentizität und Autopsie.</s>
+ <s>Chamissos Texte geben ebenso Auskunft über kulturelle Konzepte, die sich erst über eine zweite, diskurshistorisch und kontextorientierte Herangehensweise erschließen.</s>
+ <s>Paradigmatisch hierfür steht seine Auseinandersetzung mit dem Konzept der
+ <hi rend="italic">Generation</hi>, das ihn einmal mehr als Figur des Übergangs ausweist, dieses Mal auf dem Gebiet der modernen Naturwissenschaften.</s>
+ <s>Bis zur Mitte des 19. Jahrhunderts konkurrieren dort zwei diametral entgegengesetzte Modelle miteinander: Auf der einen Seite die aus früheren Epochen tradierten Konzepte der Idealgenese, welche die Arten des Tier- und Pflanzenreichs in Konstanz und Invarianz sowie in einer aufsteigenden Reihe vom Einfachen zum Komplexen, mit dem Menschen als Krone von Gottes Schöpfung ordnen, auf der anderen Seite die zunehmend einflussreichen Vorstellungen der Realgenese, welche die botanischen und zoologischen Entwicklungen aus empirischen Prozessen der Verer-
+ <pb break="no" n="126"/>bung und als Anpassung von Organismen an ihre Umwelt beschreiben (vgl.
+ Graczyk
+ 308-313
+ ). Chamissos Beitrag zu dieser Debatte situiert sich auf dem Spezialgebiet der Algologie.</s>
+ <s>Gemeinsam mit Eschscholtz entdeckt er auf der Fahrt von Plymouth nach Teneriffa acht neue Arten der Salpen, wirbellosen Manteltieren, die sich von Plankton ernähren, zum größten Teil aus ihrem Kiemendarm bestehen, sich in langen Ketten an der Meeresoberfläche bewegen und weniger als zehn Zentimeter an Länge messen.</s>

+ <s>Auf die entscheidende Beobachtung bei seinen Forschungen geht Chamisso im fünften Kapitel seiner Reisebeschreibung genauer ein.</s>
+ <s>Dort heißt es:

+ <s>Der Generationswechsel der Salpen erfolgt durch Metagenese: Auf die erste Generation, die sich ungeschlechtlich durch Teilung vermehrt, folgt die zweite, die sich geschlechtlich durch Paarung fortpflanzt.</s>

+ <s>Mit den Formulierungen dieses letzten Satzes alludiert Lotman auf die Aristotelische
+ <hi rend="italic">Poetik</hi> und hebt zugleich ins Bewusstsein, dass in der Literatur des 19. und 20. Jahrhunderts ein literarischer und historiographischer Text von der Faktur her oftmals ununterscheidbar sind und wir sie doch, gewissermaßen automatisch, in völlig unterschiedlicher Art decodieren, ja sich unsere Lektüre eines historiographischen Texts, etwa einer Zeitungsnotiz, augenblicklich ändert, sobald dieser Eingang findet in ein Druckerzeugnis, welches uns mit je spezifischen Mitteln signalisiert, das zu Lesende sei Literatur.</s>
+ <s>Man könnte diese zweite Ebene der Lektüre: das Schicksal der Anna Karenina als
+ <quote>,Abbildung des Schicksals jeder Frau, ja jedes Menschen‘</quote>, als eine rhetorische, symbolische oder auch allegorische Lektüre bezeichnen, in dem Sinne, dass wir dem Text unterstellen, er meine zusätzlich noch etwas anderes, als was er zunächst sagt.</s>
+ <s>Wie schon das Lotman-Zitat impliziert, ist diese zweite Ebene der Decodierung eine solche, deren Bezeichnetes im Unterschied zur ersten im gegebenen Text nicht konstituiert ist (
+ <quote>‚die Abbildung eines anderen Objektes, das zu unbegrenzter Ausweitung tendiert‘</quote>).</s>
+ <s>Die symbolische Ebene des Texts wird vom jeweiligen Leser im Akt der Lektüre entworfen.</s>
+ <s>Wie jeder Akt der Symbolisierung, das heißt der Zuweisung von Bedeutung, ist sie deshalb letztlich beliebig, oder, in der Terminologie Umberto Ecos,
+ <quote>,offen‘</quote>.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Das Spezifische der Lektüre des literarischen Texts, bzw. dessen Part, über den ich im Moment handele, wäre aus dieser Perspektive möglicherweise eine Art von Lust am Schöpferischen.</s>
+ <s>Auf der Grundlage der primären Mitteilung des Texts (in diesem Fall dem Bericht vom tragischen Schicksal einer Frau namens Anna Karenina) ist der jeweilige Leser frei, im Prozess des Betrachtens und des schwebenden Nachdenkens eine eigene, allgemeinere Bedeutung des Texts zu entwerfen, die letztlich nur der Anforderung zu genügen hat, in einer sinnvollen Zeichen-Bezeichneten-Relation zu der primären zu stehen.</s>
+ <s>Über die Rigorosität dieser Anforderung indes, über den Grad der ‚Stimmig-
+ <pb break="no" n="15"/>keit‘ der Lektüre und auch über den Grad der Exaktheit, das heißt Transparenz, befindet allein der einzelne Leser selbst.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Dieser konstruktive Part der Decodierung eines literarischen Texts hat Affinitäten zu dem, was wir als Spiel bezeichnen.</s>
+ <s>Dieses Spiel würde sich ansiedeln in jener intermediären Zone zwischen den Daten der Sinneswahrnehmung und dem völlig unsinnlich Konzeptuellen, welche wir in unserer Kultur die
+ <term rend="italic">phantasmata</term> nennen, der Synthetisierung von Sinnesdaten zu ,Bildern‘, die dem entsprechen können, was wir für die Realität halten, die jedoch nicht notwendigerweise auf den Realnexus verpflichtet sind, sondern auch mögliche, wünschbare oder schreckliche Varianten von Welt in unserem Bewusstsein erzeugen können.</s>
+ <s>Das Spielerische der Lektüre stünde zunächst also für die Freistellung von unmittelbar pragmatischen Folgen.</s>
+ <s>Wir müssen für diese oder jene Interpretation eines literarischen Texts nicht eventuell mit unserem Ruf, unserem Geld oder gar unserem Leben einstehen, selbst wenn wir unsere Lektüre publik machen.</s>
+ <s>Und als normale, das heißt nicht-institutionelle Leser müssen wir im Unterschied zum authentischen Künstler, für den das ‚Schöpferische‘ in der Regel harte, zuweilen quälend harte Arbeit ist, das Produkt unserer Weiter- oder auch Neu-Schöpfung des gegebenen Texts niemals irgendeinem Publikum als fertiges Werk zur allgemeinen Beurteilung ab- bzw. ausliefern.</s>
+ <s>Das Spielerische meint also die Marge des Nachdenkens über Ernsthaftes ohne ernsthafte Folgen wie auch das Tentative, die Momente des Unabschließbaren und des immer wieder Neuen.</s>
+ <s>Es steht für die Entlastung vom Druck des Realitätsprinzips in einer Situation, die ungeachtet dessen aber nicht die der völligen Emanzipation vom Lebenspraktischen ist, wie im Fall der Musik.</s>
+ <s>Was Kant
+ <quote>‚ästhetische Ideen‘</quote> genannt hat und was man auch das Phantasmatische nennen könnte, steht im Fall des Wortkunstwerks für die Anwesenheit der symbolischen Ordnung und zugleich für die partielle Befreiung von jener Komplexitätsreduktion, die sie uns auferlegt.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Wenn wir uns als Literaturwissenschaftler sehen, befinden wir und also in der einigermaßen misslichen Lage, dass eine wesentliche Dimension unseres Gegenstands, des Literarischen, am einzelnen Objekt, das heißt
+ <term rend="italic">in concreto</term> schwerlich nachvollziehbar zu machen ist.</s>
+ <s>Wir können in unseren theoretischen Reflexionen darauf hinweisen oder uns damit begnügen, die entsprechenden theoretischen Reflexionen jener Riesen in Erinnerung zu halten, auf deren Schultern wir stehen , ohne indes, so scheint es mir, wesentlich weiter zu blicken als jene.</s>
+ <s>Aber der Versuch, das Spielerische, Schwebende der Literatur anhand eines gegebenen Falls, eines singulären Texts, kommunikabel zu machen, tendiert zu Banalität oder endet gar in Peinlichkeit.</s>
+ <s>
+ <pb n="16"/>Nun müssen wir daraus nicht die Konsequenz ziehen, den Antrag auf augenblickliche Schließung der literaturwissenschaftlichen Seminare zu stellen.</s>
+ <s>ich erinnere nochmals an das gebrachte Lotman-Zitat und würde sagen wollen, dass jene
+ <quote>,unbegrenzte Ausweitung‘</quote>, zu der ein partikulärer Text tendiert, sobald wir ihn als literarischen lesen, den Raum definiert, in dem sich das Spielerische, das Ästhetische, das Genussvolle entfaltet, das wir bei der Lektüre empfinden.</s>
+ <s>Aber Lotman nennt diesen Aspekt als letzten und er ordnet ihm beispielhaft drei andere Aspekte vor (
+ <quote>‚das Schicksal der Heldin als Abbildung des Schicksals jeder Frau einer bestimmten Epoche und einer bestimmten sozialen Schicht, jeder Frau überhaupt, ja jedes Menschen‘</quote>).</s>
+ <s>Diese Aspekte würde ich als mögliche Varianten (das heißt: weitere wären denkbar) dessen bezeichnen, was ich im Unterschied zum gerade erörterten spielerischen Allgemeinen das definite Allgemeine des literarischen Texts nennen will und das mit Aristoteles‘ Bemerkung auf den Nenner gebracht ist, der literarische Text sei insofern er immer auch Mitteilung eines Allgemeinen ist, etwas Philosophischeres als der historiographische.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Wenn es kulturübergreifend und über einige Jahrtausende hin Texte gibt, die man zugleich als das liest, was sie
+ <term rend="italic">prima facie</term> sagen, und als Mitteilung eines anderen, Allgemeinen, was in ihnen nicht explizit gesagt ist, gibt es offensichtlich eine persistentes Bedürfnis auf allgemeine Reflexion des Partikulären, anders gesagt, auf Sinnbildung.</s>
+ <s>Und es gibt offensichtlich keine geeigneteres Instrumentarium auf Erfüllung dieses Bedürfnisses der Anschauung des Partikulären als Allgemeines als die Lektüre literarischer Texte, soweit es eben nicht um das Wiederfinden einer prästabilisierten, das heißt etwa einer metaphysisch-theologischen, sondern um das tentative Erproben einer möglichen Sinnbildung geht.</s>
+ <s>So scheint mir unsere Bemühung, das literaturwissenschaftliche Deuten von Texten, im Prinzip genau so sinnvoll oder aber absurd wie alle anderen Bemühungen, die auf die Stillung unserer Bedürfnisse ausgehen und die sich allesamt, bis hin zur Beschaffung von Nahrung oder der Heilung von Krankheiten, in Ansehung, sei es der Unvermeidlichkeit unseres Todes, sei es der von Borges in seiner Erzählung
+ <title rend="italic">El Immortal</title> erläuterten Unerträglichkeit eines Lebens ohne Ende, einer Letzt-Begründbarkeit entziehen.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Zu erwägen bliebe gleichwohl, ob, wenn Lektüre des Partikulären als Codierung eines Allgemeinen eine Art anthropologisches Bedürfnis erfüllt, es der Institutionalisierung einer solchen Lektürepraxis bedarf, also dessen, was wir im Deutschen mit dem vielleicht etwas unglücklichen Terminus
+ <term>‚Literaturwissenschaft‘</term> belegen.</s>
+ <s>Letztlich ist jede Texthermeneutik zunächst Individualhermeneutik, und zwischen den Dokumenten solcher Individualhermeneutik
+ <pb n="17"/>zu operieren, soweit sie Praktiken einzelner Leser sind und bleiben ist unmöglich.</s>
+ <s>Jede individuelle Lektüre, so trivial und begrenzt sie auch sein mag, ist darin gerechtfertigt, dass sie für den jeweiligen Leser das skizzierte Grundbedürfnis, das auch die geläufigen Praktiken der phantasmatischen Identifikation umfasst, zu erfüllen vermag.</s>
+ <s>Der trans-individuelle Belang der Lektüren entsteht also einzig daraus, dass das Produkt einer solchen Individualhermeneutik in der Lage ist, auch andere Leser zu interessieren, und dieser Belang ist umso größer, je mehr solcher im Prinzip Interessierten eine derartige individuelle Lektüre aktuell zu interessieren vermag.</s>
+ <s>Nicht intersubjektive Nachprüfbarkeit, das heißt Wissenschaftlichkeit, sondern intersubjektive Resonanzerzeugungsfähigkeit, dies scheint mir das Kriterium, an dem sich die Früchte literaturwissenschaftlicher Bemühungen bzw. deren Wert bemessen.</s>
+ <s>Dies wiederum heißt nichts anderes als den Belang der Lektüren an das gebunden zu sehen, was ein gegebenes soziales Gefüge, eine Diskursgemeinschaft (anglo-amerikanisch: eine
+ <hi rend="italic">
+ <foreign xml:lang="en">community</foreign>
+ </hi>)zu einer gewissen Zeit interessiert bzw. was sie interessieren sollte.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Diese letztere Formel – was sie, eine
+ <hi rend="italic">
+ <foreign xml:lang="en">community</foreign>
+ </hi>, interessieren sollte – klingt nach der Wiederbelebung obsoleter Wahrheitsansprüche, aber sie ist anders gemeint.</s>
+ <s>Lektüren, die einzig dem Rechnung tragen, was eine gegebene Gemeinschaft zu einem gegebenen Zeitpunkt wie selbstverständlich interessiert, sind tendenziell langweilig.</s>
+ <s>Sie machen keine neuen oder partiell neuen Sinnangebote, sondern repristinieren bekannte.</s>
+ <s>Insofern sind sie, also alles das, was ich den
+ <hi rend="italic">
+ <foreign xml:lang="en">mainstream</foreign>
+ </hi> unserer Fächer nennen möchte, von schwacher Resonanzerzeugungsfähigkeit.</s>
+ <s>Die anderen ‚starken‘ Lektüren, die sich mit neuen oder reprofilierten Sinnangeboten auf den Markt der Möglichkeiten begeben, sind riskante Lektüren.</s>
+ <s>Sie können ganz ohne Aufmerksamkeit bleiben oder aber diese Aufmerksamkeit erst finden, wenn ihre Verfasser bereits verblichen sind.</s>
+ <s>Sie können enthusiastische Aufnahme finden und doch bereits wenige Jahrzehnte danach als mitverantwortlich für große moralische oder soziale Katastrophen am Pranger stehen.</s>
+ <s>Was zugleich interessant und
+ <foreign xml:lang="en">,helpful‘</foreign> ist, wie man in den USA sagt, lässt sich vom Standpunkt der Gegenwart aus nicht beurteilen, sondern immer erst aus der Rückschau auf eine abgeschlossene Epoche, und es ist eine verbreitete, aber unrettbar naive Blindheit, in einer jeweiligen Gegenwart zu sagen man hätte einstmals sicher gewusst, welche Art von Hermeneutik jener Zeit gefrommt hätte.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>So ist es denn immer unserem jeweiligen
+ <term rend="italic">iudicum</term> anheim gegeben zu entscheiden, was denn nun unserer Zeit frommt: Lektüren, die die kulturelle Konstruiertheit von Geschlechterrollen ins Bewusstsein heben oder solche, die
+ <pb n="18"/>auf die Begrenztheit einer derartigen Sicht verweisen bzw. sie gar ignorieren, Lektüren, die auf Subversion ausgehen oder auf die Wiedererinnerung an die Positionen der

+ <term rend="italic">horribile dictu</term> – des Lasteroktonars der Religion unserer Väter, Lektüren, die auf Autoreferentialität oder Mimetizität aus sind, auf Dekonstruktion (was ja auch eine Form von Sinnbildung ist) oder auf einen stabilen Sinn.</s>
+ <s>Ob wir uns als jeweiliger Leser mit diesen Varianten in Übereinstimmung mit dem, was unsere jeweilige Zeit erfordert, befunden haben oder nicht, werden wir vermutlich in den meisten Fällen nie erfahren, und es ist in Ansehung dessen, was alles gedruckt wird, auch zweifelhaft, dass die Reflexion auf diese Zusammenhänge das Gieren nach dem schnellen Erfolg im
+ <term rend="italic">hic et nunc</term> zu zügeln vermag.</s>
+ <s>Letztlich befinden wir uns damit in einer Situation, die sekundär die der Verfasser unserer Texte, das heißt der literarischen Texte, nachbildet.</s>
+ <s>Wenn diese handwerklich, auf lateinisch: artistisch, gut gemacht sind, sind sie schön, aber für ihren bleibenden Wert ist das eine Beigabe, nicht das entscheidende Moment.</s>
+ <s>Wahr sind sie allesamt nicht.</s>
+ <s>Und ob sie gut, im Sinne von
+ <foreign xml:lang="en">‚useful‘</foreign> oder
+ <foreign xml:lang="en">‚helpful‘</foreign> sind, entscheidet sich erst lange Zeit nach ihrem Entstehen.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Ich möchte mich abschließend beziehen auf die modellhafte Beschreibung der Lektüre, die Hans Robert Jauß in seinem Essay
+ <title>„Zur Abgrenzung und Bestimmung einer literarischen Hermeneutik“</title> geliefert hat.</s>
+ <s>Ich übernehme das dort entwickelte Drei-Stufen-Schema, mit einer soweit ich sehe, allerdings eher geringfügigen Variation in der Beschreibung der drei Stufen.</s>
+ <s>Vor allem liegt mir daran zu unterstreichen, dass Jauß die ästhetische Erfahrung des literarischen Texts, die er in Kantischer Tradition mit dem Terminus des
+ <term>‚Genießens‘</term> belegt und die ich das
+ <term>‚Spielerische‘</term> genannt habe, von den zwei anderen, sinndeutenden Stufen separiert.</s>
+ <s>Ich argumentiere über Jauß hinaus, dass die theoretische Beschreibung dieser Stufe zu unserer Profession gehört, nicht aber die Befassung damit am einzelnen Objekt.</s>
+ <s>Die zwei anderen Stufen bezeichnet Jauß, erstens, als die der Rekonstruktion der seinerzeitigen Botschaft des Werks, sowie zweitens, als die der Befragung auf aktuell virulente Probleme hin.</s>
+ <s>Ich würde diese zwei Stufen – eingedenk der hermeneutischen Basis-Annahme, dass es keine Rekonstruktion des Vergangenen geben kann, die nicht in gegenwärtigem Interesse gründet – zu einer einzigen machen wollen und ihr als erste Stufe die eingangs skizzierten, von der Pragmatik und der Dekonstruktion entwickelten Gesichtspunkte zur prinzipiellen Prekarität sprachlicher Äußerungen, das heißt auch nicht-literarischer, vorordnen wollen.</s>
+ <s>So würde zwar Gadamers Diktum, dass im Fall des literarischen Texts die Ästhetik in der Hermeneutik aufgehe
+ <ref>(157)</ref>, nicht vorbehaltlos, wohl aber in dem
+ <pb n="19"/>Sinne unterschreiben wollen, dass es diese, die hermeneutische Dimension literarischer Texte ist, über die sich eine Rede führen lässt, die den Anspruch erheben kann, gehört zu werden.</s>

+ </hi> der Gelehrtenrepublik, dessen immense Korrespondenz schon von den Zeitgenossen bestaunt wurde, der sich mit allen Gebieten des damaligen Wissens produktiv und innovativ beschäftigte … Leibniz, der Jurist und Geheime Justizrat am Hof zu Hannover, an dem er die größere Hälfte seines Lebens verbrachte, war dort vor allem eines: der Historiker vom Dienst.</s>
+ <s>
+ <pb n="44"/>
+ </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Jedenfalls würde man das heute so sagen.</s>
+ <s>Leibniz selbst hat sich zeitlebens dagegen verwahrt, als braunschweig-lüneburgischer Hofhistoriograph bezeichnet zu werden.</s>
+ <s>2 Das soziale Kapital, das ihm der Hofdienst in der – gelehrten wie politischen – Welt verschaffte, resultierte aus seiner in formellen Funktion als gelehrter und amüsanter Gesprächspartner von Fürsten und vor allem Fürstinnen 3 – aber nicht aus der im höfischen Reglement weit unten angesiedelten Charge eines Historiographen.</s>
+ <s>4 </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Für uns, die wir uns in Generationen entstandenen Leibniz-Bildern gegenübersehen, ist die Historie bei ihm auf andere Weise negativ konnotiert: verbunden mit einem groß angelegten historischen Werk im Dienste des Welfenhauses, das Leibniz über 30 Jahre lang beschäftigen, seine Kräfte immer wieder absorbieren, das Verhältnis zu seinem Fürstenhof zunehmend belasten sollte, und das er schließlich bei seinem Tod im November 1716, kurz vor einem Etappenziel, unvollendet zurückließ.</s>
+ <s>5 Erst 130 Jahre später, um die Mitte des 19. Jahrhunderts, wurde der Hauptteil, die
+ <title rend="italic">Annales Imperii Occidentis Brunsvicenses</title> von 768 bis 1005 (geplant war zuletzt: bis 1024) veröffentlicht.</s>
+ <s>6 Leibniz hatte sich für diese Aufgabe, die seine zen trale
+ <pb n="45"/>dienstliche Verpflichtung werden sollte, einst selbst vorgeschlagen.</s>
+ <s>7 In späteren Jahren wird er sie als seinen „Sisyphosstein“ bezeichnen, 8 gegen Ende seines Lebens wird sie zur Erklärung für die Zurückstellung seines philosophisch-mathematischen Œuvre und der gelehrten Korrespondenzen und zum Grund für bittere Klagen über die geringe Achtung, die ihm von Seiten seines Fürstenhauses entgegenkomme, ihm, dem in ganz Europa berühmten: 9 die Historie verkörpert, so hat es den Anschein, einen geradezu tragischen Aspekt in Leibniz’ Leben und Werk.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Das klingt zugespitzt – aber ein Blick in Leibniz-Biographien, in Leibniz-Artikel, in die Leibniz-Rezeption zeigt: das entspricht einem verbreiteten Leibniz-Bild.</s>
+ <s>10 An diesem Bild, das sich spätestens im letzten Drittel des 19. Jahrhunderts aufgebaut hat, 11 hat auch ein Perspektivenwechsel einige
+ <pb n="46"/>Jahrzehnte später nicht viel geändert.</s>
+ <s>Untersuchungen, die (etwa seit der Mitte des 20. Jahrhunderts) nach einem „Mehrwert“ der Beschäftigung des Historiographen Leibniz für den hannoverschen Hof fragten, kamen tendenziell zu einem vernichtenden Ergebnis: der Universalgelehrte war dienstlich eigentlich ziemlich untragbar.</s>
+ <s>12 Vor allem wegen der Welfengeschichte, die unendlich viel an Ressourcen verschlang und ziemlich eigenwillig ausgeführt wurde (allein schon in der Wahl der Gelehrtensprache Latein, nicht der Hofsprache Französisch), ein Werk, dessen Konzeption mehrfach geändert, 13 das immer wieder als bald vollendet angekündigt, aber nie fertiggestellt wurde, das vom Kurfürsten resigniert mit der „Weißen Frau“, also einem Phantom verglichen wurde.</s>
+ <s>14 Ob als Fessel oder als verweigerte Arbeit: die Hausgeschichte (die übrigens auch von Generationen von Historikern nach Leibniz nicht vollendet werden konnte 15 )scheint der dunkle Punkt in der großen Leibniz-Erzählung zu sein.</s>

+ <s>Ein Desiderat der Leibniz-Forschung: die Historischen Schriften</s>
+ </head>
+ <p>
+ <s>Nun sind Bilder das eine, Forschungsergebnisse etwas anderes.</s>
+ <s>Aber auch die Forschung über den Historiker Leibniz tritt nicht als Erfolgsgeschichte auf.</s>
+ <s>Ein Blick in die Leibniz-Bibliographie zeigt es: 17 den 91 Treffern, die das Schlagwort „Leibniz als Historiker“ derzeit ergibt, stehen allein für das philosophische Teilgebiet „Metaphysik“ 1852 gegenüber; nimmt man weitere philosophische Gebiete hinzu, so bewegt sich die Historie bei einem Anteil von etwa 2% (und auch gegenüber der Mathematik sind es nur etwa 4%).</s>
+ <s>Keineswegs wegen fehlenden Quellenmaterials; es ist schon fest ge stellt worden, dass Leibniz’ Korrespondenzen, Arbeitsmaterialien und Ausarbeitungen zur Geschichte den größten Teil des Nachlasses bilden.</s>
+ <s>18 Was fehlt, ist die Aufarbeitung in der Forschung – und bereits deren Grundlage, die Edition.</s>
+ <s>Man könnte es schon als signifikant für diese schwierige Beziehung ansehen: von den acht Reihen der historisch-kritischen Leibniz-Edition (unter Leitung der Berlin-Brandenburgischen Akademie der Wissenschaften und der Akademie der Wissenschaften zu Göttingen), die inzwischen bei bald 60 Bänden angekommen ist, 19 ist eine einzige noch nicht in Arbeit – die Reihe V mit den
+ <title rend="italic">Historischen und sprachwissenschaftlichen Schriften</title>.</s>
+ <s>Das Interesse daran wäre eigentlich groß, das spiegeln häufige Klagen über dieses Desiderat – und auch die starke Resonanz, die vor etwa 10 Jahren eine Auswahledition von Leibniz’
+ <title rend="italic">Schriften und Briefen zur Geschichte</title> gefunden hat.</s>
+ <s>20 </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Allerdings ist der Historiker Leibniz in der Akademie-Ausgabe immerhin ansatzweise sichtbar in zwei Reihen, die weit fortgeschritten sind.</s>
+ <s>Bei der einen weist bereits der Reihentitel darauf hin: der
+ <title rend="italic">Allgemeine, politische und historische Briefwechsel</title> (Reihe I), in der Bearbeitung inzwischen in Leibniz’ letztem Lebensjahrzehnt angekommen, enthält die Korrespondenz mit anderen auf diesem Gebiet wirkenden Gelehrten und die für die
+ <pb n="48"/>Historie außerordentlich aufschlussreiche mit den Mitarbeitern; sie spiegelt auch Leibniz’ Teilnahme am historischen Diskurs seiner Zeit.</s>
+ <s>21 </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Bei der anderen, deren jüngster Band soeben das Jahr 1700 erreicht hat, den
+ <title rend="italic">Politischen Schriften</title>, 22 ergibt sich der Bezug aus der zeitgenössischen engen Verbindung von Politik und Geschichte.</s>
+ <s>Leibniz’ Schaffen auf dem Gebiet der Historie war keineswegs auf die welfische Hausgeschichte beschränkt.</s>
+ <s>Er war wirklich der Historiker vom Dienst.</s>
+ <s>Ob mit einem elaborierten Bildprogramm zur fürstlichen Repräsentation oder der Bereitstellung von rechtshistorisch fundierten Argumenten in Auseinandersetzungen um Rang, Hoheit, Rechte, Besitz oder für die dynastische Heiratspolitik: 23 Leibniz hat für den Hof zu Hannover stetig im Hintergrund gewirkt, als – wie Günther Scheel, lang fast als einziger mit der Materie befasst, es einmal formuliert hat – „Sachbearbeiter und Referent“.</s>
+ <s>24 Dabei entstanden zahlreiche Schriften, die übrigens zeigen, dass dieser Historiker für Hannover keinesfalls eine Fehlinvestition war.</s>
+ <s>25 Aber sie blieben, vor allem für den
+ <pb n="49"/>hofinternen Gebrauch bestimmt, zu seinen Lebzeiten zumeist unveröffentlicht (und wenn veröffentlicht, dann unter Pseudonym 26 ). Durch die Edition in den
+ <title rend="italic">Politischen Schriften</title> tritt dieses Wirken zunehmend zutage: dort, wo Historie evident politisch ist, nimmt der Historiker Leibniz bereits mehr Kontur an.</s>
+ <s>Immer noch ist er aber nicht eigentlich Gegenstand eines lebendigen Diskurses.</s>
+ <s>An der unvollständigen editorischen Aufbereitung allein kann es nicht liegen: sie gilt für Leibniz’ Œuvre insgesamt.</s>
+ <s>Während die Forschung sich in anderen Gebieten aber nicht von einer regen Diskussion abhalten lässt, tritt sie der Historie, dem
+ <hi rend="italic">opus magnum Annales</hi> zumal, nur zögernd gegenüber – warum?</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Darauf gäbe es ein ganzes Bündel von Antworten.</s>
+ <s>Eine wäre: 2300 Seiten in Latein, wie sie die
+ <title rend="italic">Annales Imperii</title> in der Ausgabe von 1843–1846 einnehmen, ohne Erschließungselemente wie Register, sind auch für Fachhistoriker eine ziemliche Herausforderung.</s>
+ <s>Eine andere: Dieses Mammutwerk, als Zwitter zwischen Hausgeschichte und einer Reichsgeschichte der Karolinger- und Ottonenzeit wahrgenommen, 27 fällt formal und gattungsgeschichtlich durch sämtliche Raster und erschien überhaupt zur Unzeit.</s>
+ <s>Um die Mitte des 19. Jahrhunderts, im Vorfeld der Reichseinigung, 28 hatte sich das Genre dynastische Hausgeschichte eigentlich überlebt.</s>
+ <s>Für die aufblühende Reichsgeschichte war mit den
+ <title rend="italic">Jahrbüchern der deutschen Geschichte</title>
+ <pb n="50"/>ein ähnlich aufgebautes Grundlagenwerk im Entstehen; 29 auf Deutsch, ohne den Hautgout des territorialen Partikularismus: die
+ <title rend="italic">Annales</title> sind zu spät im Druck erschienen, um noch Gegenstand der Diskussion zu werden.</s>
+ <s>30 Allerdings muss ich sogleich relativieren: vereinzelt lässt sich schon Rezeption finden, aber eben weniger im historiographiegeschichtlichen Diskurs als in der mediaevistischen Detailarbeit; hier hat der Historiker Leibniz durchaus Spuren hinterlassen.</s>
+ <s>31 </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>In diesem Zusammenhang gäbe es eine weitere Erklärung, und sie möchte ich jetzt in den Mittelpunkt stellen.</s>
+ <s>Wer Leibniz’
+ <term rend="italic">opus historicum</term> gegenübertritt, findet darin durchaus Antwort auf traditionelle ideengeschichtliche Fragen wie nach Geschichtsdenken und philosophie, nach historischer Narration und Methode, zur Einordnung in den Kontext der barocken Geschichtswissenschaft und der Historiographie-Geschichte überhaupt.</s>
+ <s>32 Aber vor allem anderen findet er – überreich, geradezu erschla gend – Material für einen aktuellen Ansatz: Wissenschaft (hier also Geschichtswissenschaft) als gelehrte Praxis.</s>

+ <s>
+ die handelnden Personen gesellschaftliche Aufsteiger.</s>
+ <s>Und wiederum sind sowohl Mörder als auch Opfer Frauen und die Geschlechterverhältnisse ein zentrales Thema.</s>
+ <s>Die Motivation der Täterin hier ist ihr unbedingter Wille, durch eine passende Heirat in bessere Verhältnisse zu kommen.</s>
+ <s>Dass der Auserwählte vorerst noch verheiratet ist, wenn auch getrennt lebend, ist ein Hindernis, das sie durch den Giftmord an der Noch-Ehefrau beseitigt.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Dem Leser werden auch in dieser Detektivgeschichte anschauliche Milieustudien vermittelt.</s>
+ <s>Julija Nikolaevna, die Täterin, kommt im Alter von zwei Jahren zu

+ <s>Dort genießt sie wie eine Tochter des Hauses das entsprechende Erziehungsprogramm mit Musik, Tanz und Konversation, das sie für eine standesgemäße Heirat vorbereiten soll.</s>

+ <hi rend="italic">maman</hi>.</s>
+ <s>Damit sieht Julija den Kontrakt erfüllt, nimmt sich ihrerseits alle Freiheiten und empfängt Gäste, darunter auch männliche.</s>
+ <s>Als einzig möglichen Ausweg aus ihrer verfahrenen Situation sieht sie die Instrumentalisierung ihrer sexuellen Attraktivität, um einen in Leidenschaft entbrannten Verehrer dazu zu bringen, ihre Scheidung in die Wege zu leiten und ihr einen adäquaten, ehrbaren Ehestand zu bieten.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Achšarumov wählt einen ambitionierten Darstellungsmodus aus der abwechselnden Ich-Perspektive von zwei Erzählern, wodurch sich eine Art Doppelbelichtung ergibt.</s>
+ <s>Die eine Perspektive ist die Julijas und die andere die des Cousins des Mordopfers, der die Ermittlung zu seiner Angelegenheit macht.</s>
+ <s>Dieser Erzähler, Sergej Čerezov, ist ein 35jähriger Petersburger, ein enttäuschter Intellektueller, der für seinen bescheidenen Lebensunterhalt bei einer Handelsgesellschaft arbeitet.</s>
+ <s>Auf der Besuchsfahrt zu seiner Cousine Ol’ga, die seit der Trennung von ihrem Ehemann in einer Provinzstadt bei ihrer Mutter lebt, lernt er im Zug eine schöne, Zigarren rauchende Unbekannte kennen.</s>
+ <s>Einige Zeit später erfährt er von Ol’gas Ermordung, und sein Verdacht verstärkt sich, dass eben diese Dame im Zug die Mörderin sein könnte.</s>
+ <s>Zufällig trifft er die Frau in Sankt Petersburg wieder.</s>
+ <s>Er erfährt, dass sie geschieden und inzwischen die arrivierte Gattin seines Bekannten Pavel ist.</s>
+ <s>Von nun an will er sie dazu bewegen, ihm gegenüber ein Geständnis abzulegen.</s>
+ <s>Das leidenschaftliche Verhältnis, das sich zwischen den beiden entspinnt, verkompliziert die Situation.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Erzähltechnisch sind Sergej und Pavel zwei Figuren, die über Vorzüge und Nachteile im Charakter und Verhalten von Julija und Ol’ga räsonieren und die Institution der bürgerlichen Ehe zur Diskussion stellen: Was bedeutet sie für Frauen und was für Männer, wie werden sie darauf vorbereitet, und wie kann man eine Ehe beenden.</s>
+ <s>Sergej, der unverheiratete Eheskeptiker, sieht die Ehe für einen
+ <hi rend="italic">
+ <foreign xml:lang="ru">raznočinec</foreign>
+ </hi>, der von seiner Arbeit leben muss, nur als eine zusätzliche Bürde, während sie für Frauen aus seiner Sicht die Erfüllung ihrer Träume und das Ende aller Anstrengungen ist (Achšarumov
+
+ <date instant="false">1992</date>,
+ <ref>8</ref>).</s>
+ <s>Pavel stößt im Prinzip in dasselbeHorn, wenn er seine Ehe mit der ermordeten Ol’ga beschreibt: Sie habe sich zusammengerissen, bis sie am Ziel war, und sei dann in sich zusammengefallen.</s>
+ <s>Er meint, dass sie im Prinzip ein guter Mensch war, dass ihr jedoch jegliche Substanz gefehlt habe
+ <ref>(28)</ref>.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Im Roman kommt deutlich zum Ausdruck, dass die Schuld für die Misere der bürgerlichen Ehe in der falschen Mädchenerziehung liegt.</s>
+ <s>Julija fühlt sich zu nichts anderem als zu einem Leben als wohlsituierte Dame befähigt.</s>
+ <s>Sie kann sich einen Lebensunterhalt durch Arbeit gar
+ <pb n="57"/>nicht vorstellen, wie sie ihrem revolutionär-demokratisch eingestellten Künstlerfreund erklärt, der ihr ein gemeinsames Leben vorschlägt
+ <ref>(60)</ref>.Und Ol’ga wiederum hängt an der romantischen Vorstellung, dass einmal verheiratet für immer verheiratet heißt, egal wie unglücklich man dabei ist.</s>
+ <s>Mit ihren 25 Jahren gibt sie sich selbst auf, wie Sergej bei seinem Besuch feststellt: Sie lebe nur in der Vergangenheit und wolle sich gar keine Zukunft für sich selbst vorstellen
+ <ref>(18)</ref>.</s>
+ <s>Das Ansinnen vonPavel, in eine Scheidung einzuwilligen, weist sie entrüstet zurück – dies allerdings nicht nur aus weltanschaulichen Gründen, sondern auch aus Angst vor dem damit verbundenen Skandal.</s>
+ <s>Im Gegensatz zu Olʼga sieht Julija die Scheidung von ihrem ersten Ehemann als Rettung und lässt Pavel das mit Geld regeln.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Mit der Scheidungsproblematik greift Achšarumov eine Diskussion auf, die in der russischen Gesellschaft der 1860er Jahre mit aller Heftigkeit geführt wurde.</s>
+ <s>Anders als die westeuropäischen Staaten, die ab Mitte des 19. Jahrhunderts Ehegesetze in das bürgerliche Recht verlagerten und Scheidungen erleichterten, verschärfte Russland seine diesbezüglichen Gesetze und beließ der Kirche, genauer gesagt dem Heiligen Synod, das letztinstanzliche Urteil (Mal’cev
+
+ <date instant="false">2013</date>).</s>
+ <s>Dieseranerkannte für eine Scheidung jedoch nur vier Gründe: Einer war die physische Unmöglichkeit, die Ehe zu vollziehen.</s>
+ <s>Dies wurde aber sehr restriktiv ausgelegt und bezog sich nur auf Impotenz, und das nur zum Zeitpunkt der Eheschließung, was dem Arzt, der eine solche feststellen sollte, zum Zeitpunkt der Scheidung zweifellos Schwierigkeiten bereiten musste.</s>
+ <s>Der zweite Grund war die lange Abwesenheit unbekannten Aufenthalts eines der Gatten.</s>
+ <s>Der dritte war die Verurteilung eines Ehepartners zu einer mehrjährigen Haftstrafe unter Aberkennung der bürgerlichen Rechte, was praktisch gleichzusetzen war mit einer Verbannung nach Sibirien (Bil’šaj
+
+ <date instant="false">1959</date>,
+ <ref>108</ref>).</s>
+ <s>Und der vierte Grund war schließlichEhebruch, der auch dann zur Anwendung kam, wenn sich die Eheleute einvernehmlich scheiden lassen wollten.</s>
+ <s>Diese Prozedur war in der Tat unangenehm genug, da das eigene Eingeständnis eines Ehebruchs nicht ausreichte.</s>
+ <s>Man brauchte vielmehr zwei Zeugen, die den Geschlechtsakt gesehen haben mussten, und zwar im Detail.</s>
+ <s>Trotz dieser Hürden war Ehebruch der häufigste Scheidungsgrund.</s>
+ <s>Meist nahm der Mann den Part des Ehebrechers auf sich, und Zeugen fanden sich gegen Geld.</s>
+ <s>Pikante Fälle, vor allem aus dem hohen Adel, wurden gerne in der Presse besprochen, wobei insbesondere die Zeugenpraxis Anlass für Hohn und Spott war.</s>
+ <s>Billig kam eine Scheidung auch nicht; man musste sie sich leisten können, denn sie kostete 3.000 bis 5.000 Rubel, was etwa
+ <pb n="58"/>drei Jahresgehältern eines Arztes oder eines Lehrers entsprach (Mal’cev 2013).</s>
+ <s>Dementsprechend selten waren Scheidungen: Im Jahr 1840 waren es in ganz Russland nur 198, 1880 – 920, und 1890 – 942 (
+ Preobraženskij
+
+ <date instant="false">1897</date>
+ , zitiert nach
+ Mal’cev
+
+ <date instant="false">2013</date>
+ ).</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Um diese unhaltbare gesellschaftliche Situation zu modellieren, sind bei Achšarumov sowohl die Mörderin als auch das Mordopfer als ambivalente Figuren angelegt – Julija wird keineswegs in Grund und Boden verdammt, und Olʼga ist nicht nur bemitleidenswert.</s>
+ <s>Letztere ist aus der Sicht von Sergej zwar lieb und anschmiegsam, kann und will aber nicht auf eigenen Beinen stehen – zart, kränklich und blass weigert sie sich, ihre Zukunft im Rahmen des Möglichen allein zu gestalten.</s>
+ <s>Die Täterin wiederum wird als eine willensstarke, selbstbewusste, attraktive Frau charakterisiert, die ihr Schicksal beherzt in die Hand nimmt.</s>
+ <s>Sie bleibt allerdings den Denkstrukturen ihrer Erziehung verhaftet und denkt nicht daran, sich den Anforderungen und Entbehrungen einer revolutionär-demokratischen Lebensweise auszusetzen.</s>
+ <s>Da bleiben die Zigarren, die sie ab und zu raucht, und der revolutionär eingestellte Künstlerfreund, den sie, bis er ihr durch Verhaftung abhandenkommt, auf eine zurückhaltende Art liebt und schätzt, die einzigen vorsichtigen Versuche in diese Richtung.</s>
+ <s>Keine der beiden Frauen nutzt jedenfalls den Handlungsrahmen, den die russische Intelligenzija der damaligen Zeit für erstrebenswert und für machbar hielt.</s>
+ <s>Die Enttäuschung von Sergej als Intellektuellem teilt offensichtlich auch der Autor, da er weder das Modell Julija noch das Modell Ol’ga als tragfähig für die Zukunft sieht.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Bei aller Komplexität und Ambitioniertheit nimmt der Roman aber auch viele Anleihen bei Schauer- und amourösen Romanen.</s>
+ <s>Solches war in den frühen russischen Detektivgeschichten zwar durchaus üblich, trägt aber im konkreten Fall nicht zur Stringenz des Romans bei und bläht ihn unnötig auf 152 Seiten auf.</s>
+ <s>Der letzte Teil des Romans ist der Sühne des Verbrechens und der ausgleichenden Gerechtigkeit gewidmet, da ja weder die Mörderin noch ihr Ehemann der Rechtsprechung zugeführt werden.</s>
+ <s>Pavel, der maßgeblich an der Planung des Mordes beteiligt war, wird nächtens von Ol’ga als Gespenst heimgesucht und verfällt zudem einem Verfolgungswahn, da er befürchtet, von seiner Frau vergiftet zu werden.</s>
+ <s>Julija legt schließlich gegenüber Sergej ein Geständnis ab und muss den Mord mit dem Tod ihrer zweijährigen Tochter büßen.</s>
+ <s>Nach dem frühen Tod ihres Mannes zieht sich Julija aus der Öffentlichkeit zurück, widmet sich ganz der Kinderfürsorge und führt ein gottgefälliges Leben.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Das Ende des Romans ist ein Beispiel für die grundsätzliche Schwierigkeit, die Verbrechen von Frauen verursachen.</s>
+ <s>Für die russi-
+ <pb break="no" n="59"/>sche Bildungsschicht (wie auch für die europäische) stellten sie insofern eine Herausforderung dar, als sie dem kulturell codierten Bild der Frau diametral zuwiderlaufen:
+ <gap instant="false"/> Achšarumov steht vor demselben Dilemma wie die viktorianischen Schriftstellerinnen und Schriftsteller und er löst es auf ähnliche Art und Weise wie Charles Dickens, Thomas Hardy, Mary Elizabeth Braddon, Wilkie Collins oder Arthur Conan Doyle, deren Mörderinnen mit Ächtung, Wahnsinn oder Tod bestraft werden:
+ <gap instant="false"/> In den meisten literarischen Fällen wird die Mörderin zwar keinem Gerichtsverfahren zugeführt, muss jedoch, wie Morris ausführt, ihre Tat im irdischen Leben auf eine andere Art büßen und, was meist unausgesprochen dahintersteht, sich vor Gott verantworten.</s>
+ <s>Das Ende der Detektivgeschichte von Škljarevskij, in der die Täterin völlig ungestraft davonkommt, scheint eine große Ausnahme zu sein.</s>

+ <s>Der Untersuchungsrichter als Bollwerk</s>
+ </head>
+ <p>
+ <s>In den frühen russischen Detektivgeschichten ist der Untersuchungsrichter eine verbreitete Ermittlerfigur.</s>
+ <s>Von Škljarevskij gibt es z. B. einen ganzen Zyklus von Detektivgeschichten mit dem Titel
+ <title rend="italic">Rasskazy sudebnogo sledovatelja</title> („Erzählungen eines Untersuchungsrichters“).</s>
+ <s>Vorreiter für diese Figur war Dostoevskijs Porfirij Petrovič in
+ <title rend="italic">Prestuplenie i
+ <pb n="60"/>nakazanie</title>, der den Mörder Raskol’nikov so weit bringt, seine Schuld einzugestehen.</s>
+ <s>Dostoevskij nähert sich dieser Ermittlerfigur allerdings nur äußerlich, während Škljarevskij und Panov den Untersuchungsrichter zum Ich-Erzähler mit eigenen Hoffnungen und Enttäuschungen machen.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Für Russland war das Amt eines Untersuchungsrichters, wie erwähnt, damals ein Novum und Teil der großen Justizreform.</s>
+ <s>Im Jahr 1864 und in den Folgejahren kamen auf Drängen der liberalen Kräfte Gesetze zustande, die die Vielzahl von Gerichtsarten, Zuständigkeiten und Standesgerichten reduzierten und vor allem auf eine juristische Trennung von Verwaltung und Justiz abzielten.</s>
+ <s>Bis dahin waren die Gerichtsbehörden von der Gouvernementsverwaltung abhängig: Der Gouverneur nahm auf die Ernennung der Richter Einfluss, und die Ermittlungen im Strafverfahren standen unter seiner Aufsicht.</s>
+ <s>Bei kleineren Angelegenheiten war die Polizei für die Durchführung von Zivil- und Strafurteilen zuständig – es entschied also kein Gericht, sondern ein Verwaltungsorgan, was der Korruption Tür und Tor öffnete (
+ Puttkamer
+
+ <date instant="false">1999</date>,
+ <ref>406</ref>
+ ). Die Justizreform orientierte sich an einem liberalen Rechtsstaatsbegriff und an europäischen Maßstäben.</s>
+ <s>Allerdings wurde sie ohne Rücksicht auf bisherige Gewohnheitsrechte und spezifische Situationen an der Peripherie des Reiches durchgezogen, was zu Reibungen und späteren Gesetzesänderungen führte.</s>
+ <s>Insgesamt wurde (und wird) die Justizreform aber auch im Westen als eine Glanzleistung des ausgehenden Zarenreichs gelobt
+ <ref>(405)</ref>.</s>
+ <s>In Russland war mit der Reform in weitenKreisen zudem die Hoffnung verbunden, dass damit auch eine Veränderung der Gesellschaft einhergehe.</s>
+ <s>So manche Plädoyers bei Gerichtsverhandlungen zogen daher großes Interesse auf sich und wurden weit über den Anlassfall hinaus diskutiert.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Die Autoren der frühen Detektivgeschichten teilten die Hoffnung auf gesellschaftliche Veränderungen und stellten sich auf die Seite der Justizreform.</s>
+ <s>Ihren Figuren des Untersuchungsrichters ist es ein Anliegen, die Gesetze besonders korrekt einzuhalten, alle Korruptionsversuche abzuschmettern und sich auch von keiner noch so schönen, betörenden Frau vom richtigen Weg abbringen zu lassen.</s>
+ <s>Aus diesem Grund sind die russischen Untersuchungsrichter keine besonders individualistischen oder gar exzentrischen Figuren, wie man sie aus französischen oder englischen Detektivgeschichten kennt, sondern eher der Typ eines korrekten, namenlosen Beamten.</s>
+ <s>Mustergültig ist auch sein Verhältnis zur Polizei, das nicht von Rivalität geprägt ist, sondern vom Bestreben nach Zusammenarbeit.</s>
+ <s>Die Polizei wird dabei aber sehr wohl auf ihren
+ <pb n="61"/>Platz als Zuarbeiterin im Ermittlungsprozess verwiesen; und die Kriminalpolizisten (
+ <foreign xml:lang="ru">„syščiki“</foreign>), die im Gegensatz zum Untersuchungsrichterauch verdeckte Ermittlungen durchführen dürfen, erfahren mehrmals eine lobende Erwähnung.</s>

+ <p>
+ <s>Gerald Abraham war einer der Ersten, die das
+ Werk in den Begriffen der Sonate erklärten.</s>
+ <s>Er legt klar dar, wo seiner Meinung nach jeder Abschnitt
+ anfängt und warum.</s>
+ <s>Das Werk beginne mit einer doppelten <ref target="https://de.wikipedia.org/wiki/Exposition_%28Musik%29">Exposition</ref>, jede mit deutlich ausgeprägtem

+ <p>
+ <s>Robert Layton widerspricht Abraham jedoch und
+ behauptet, das Scherzo sei der Beginn der Reprise.</s>

+ <s>Die meisten Musikwissenschaftler stimmten mit
+ dieser Analyse überein, bis 1993 James Hepokoskis Untersuchung
+ erschien (<hi rend="it">Sibelius: Symphony No. 5</hi>), die eine
+ völlig andere Interpretation anbietet.</s>
+ <s>Seiner Ansicht nach kann die Sinfonie nur in Begriffen
+ einer „rotational form“, also Rotationsform
+ beschrieben werden.</s>
+ <s>Hepokoski bleibt zwar bei der üblichen Aufteilung des
+ Satzes in doppelte Exposition, Scherzo und Reprise, entwickelt aber
+ ein neues Vokabular, um die musikalische Entwicklung zu
+ beschreiben.</s>
+ <s>Sibelius erlaube in vielen seiner Werke dem musikalischen
+ Material, sich selbst eine Form zu wählen, und zwar aus der
+ Notwendigkeit der Musik selbst heraus und nicht nach vorgeformten
+ Normen des 18. oder 19. Jahrhunderts.</s>
+ <s>Er benutze eine zirkuläre Form von Rotation oder Strophe,

+ <s>Die Gibbs-Funktion wird in diesem Fall durch ein Minimum
+ festgelegt, d. h., die supraleitende Phase wird im Vergleich zur

+ umgekehrt).</s>
+ <s>Ein sich drehender Supraleiter erzeugt ein Magnetfeld, dessen

+ <s>Die Erklärung für den Zusammenbruch der Supraleitung bei
+ ausreichend hohen Magnetfeldern liegt in der Bindungsenergie der

+ zugeführt, dann brechen sie auf und es entsteht die normalleitende
+ Phase.</s>
+ <s>Die Umgebungstemperatur muss entsprechend niedriger sein, um

+ kompensieren.</s>
+ <s>Die kritische Energie kann nicht nur durch magnetische Felder

+ <s>Zur Umgebungstemperatur wurden auch Funktionen mit dem Druck

+ </p>
+ <p>
+ <s>Im Kristall besetzen die Atome bzw. Moleküle feste Lagen, die sich periodisch in alle drei Raumrichtungen wiederholen (Kristallgitter).</s>
+ <s>Die Eigenschaften eines Kristalls sind richtungsabhängig (anisotrop) [1].</s>

+ <p>
+ <s>Bei Flüssigkeiten gibt es bestenfalls eine Nahordnung.</s>

+ <s>Werden Kristalle geschmolzen, so gehen sie meist sofort in die isotrope Phase über.</s>
+ </p>
+ <p>
+ <s>Im Gegensatz dazu beginnen Flüssigkristalle am Schmelzpunkt zu fließen, gehen aber noch nicht in die isotrope Phase über, sondern behalten eine Positions- und / oder Orientierungsordnung und sind somit anisotrope Flüssigkeiten.</s>
+ <s>Erst wenn die Klärtemperatur erreicht ist, geht auch diese Ordnung verloren und die Schmelze geht ins Isotrope über.</s>
+ <s>Wie bereits erwähnt, liegen die Eigenschaften von Flüssigkristallen zwischen denen von Kristallen und denen von Flüssigkeiten.</s>
+ <s>Sie werden daher auch als
+ <hi rend="italic">Meso</hi> phasen (griech.: Mitte) bezeichnet.</s>

+ <s>Bei Flüssigkristallen wird zwischen thermotropen und lyotropen Flüssigkristallen unterschieden [2]. Lyotrope flüssigkristalline Phasen bestehen aus mindestens zwei Komponenten.</s>
+ <s>Eine davon ist das Lösungsmittel.</s>
+ <s>Sie treten innerhalb bestimmter Konzentrationsbereiche auf.</s>
+ <s>Thermotrope flüssigkristalline Phasen werden in kalamitische (stäbchenförmige) und diskotische (scheibchenförmige) Flüssigkristalle unterteilt, von denen die kalamitischen Gegenstand dieser Arbeit sind.</s>

+ <s>Die meisten thermotropen flüssigkristallinen Phasen bestehen aus Molekülen, die einen starren Molekülteil besitzen.</s>
+ <s>Solche Moleküle werden auch als Mesogene bezeichnet.</s>
+ <s>Sie neigen stark dazu, sich parallel in eine Vorzugsrichtung zu orientieren.</s>
+ <s>Je nach Orientierung spricht man von nematischen, smektischen und cholesterischen flüssigkristallinen Phasen, wobei die cholesterische mit der nematischen Phase eng verwandt ist [3]. (a)
+ <gap instant="false"/>
+ </s>
+ </p>
+ <p>
+ <s>In nematischen Phasen ordnen sich die Moleküle entlang einer Richtung, die durch den Direktor n gekennzeichnet ist und haben somit eine eindimensionale Struktur.</s>

+ <s>In einem idealen Kristall wäre der Ordnungsparameter somit eins und für eine isotrope Lösung oder Schmelze null.</s>
+ <s>Bei Flüssigkristallen liegen die Werte des Ordnungsparameters zwischen 0.3 und 0.7, was auf die thermische Bewegung der Moleküle zurückzuführen ist.</s>
+ </p>
+ <p>
+ <s>In smektischen Phasen sind die Moleküle zusätzlich in Schichten angeordnet.</s>
+ <s>Sie besitzen somit eine zweidimensionale Struktur.</s>
+ <s>Smektische Phasen sind daher auch deutlich viskoser als nematische Phasen.</s>

+ <s>1.2 Cholesterische Phasen </s>
+ </head>
+ <p>
+ <s>Cholesterische Phasen entsprechen einer verdrillten nematischen Phase und besitzen demzufolge eine helikale Struktur.</s>
+ <s>Sie werden daher auch als chirale nematische Phasen bezeichnet [3]. Ihre Entdeckung geht auf den österreichischen Botaniker Reinitzer zurück, der 1888 beim Schmelzen von Cholesterylbenzoat zwei Schmelzpunkte beschrieb [6]: Einen, bei dem die Substanz in eine trübe, aber völlig flüssige Schmelze übergeht und einen, bei dem die Schmelze völlig klar wurde.</s>
+ <s>Der Begriff „Mesophase“ wurde erst viel später 1922 von Friedel eingeführt [3].</s>

+ <s>1.2.1 Eigenschaften und Struktur </s>
+ </head>
+ <p>
+ <s>Kennzeichnend für cholesterische Phasen ist, dass sich der Direktor der Moleküllängsachsen von Molekülebene zu Molekülebene um einen bestimmten Winkel ändert.</s>
+ <s>Dies führt zu einer kontinuierlichen Verdrillung der Phase und damit zu einem helikalen Aufbau.</s>
+ <s>Der Abstand zweier Molekülebenen nach einer Drehung des Direktors um 360° wird als Ganghöhe p der Helix bezeichnet.</s>
+ <s>Die Ganghöhe liegt im Bereich von 200 bis 2.000 nm [7]. Dreht sich die Helix im Uhrzeigersinn, dann wird sie als rechtsgängig bezeichnet und ihre Ganghöhe p besitzt ein positives
+ <pb n="4"/>Vorzeichen.</s>
+ <s>Demzufolge ist eine linksgängige Helix gegen den Uhrzeigersinn gerichtet und ihre Ganghöhe besitzt ein negatives Vorzeichen.</s>
+ </p>
+ <p>
+ <s>Cholesterische Phasen treten nur bei chiralen Molekülen auf, wobei sie entweder aus geeigneten optisch aktiven Molekülen aufgebaut werden oder aus nematischen Phasen durch Zumischen eines optisch aktiven Hilfsstoffes induziert werden [5, 8]. Die Ursache für das Ausbilden der helikalen Struktur ist ausschließlich auf die Chiralität der Moleküle zurückzuführen.</s>
+ <s>Daher ist die Bildung von cholesterischen Phasen nicht auf Cholesterolderivate beschränkt, sondern auch durch Zumischen cholesterischer Flüssigkristalle [9] und auch nicht-flüssigkristalliner, chiraler Verbindungen [10, 11] zu nematischen Phasen induzierbar [12]. Dabei ist zu berücksichtigen, dass ein nicht-flüssigkristalliner chiraler Hilfsstoff die Ordnung der flüssigkristallinen Phase stört.</s>
+ <s>Dies führt dazu, dass ab einem bestimmten Anteil die flüssigkristalline Phase zusammenbricht.</s>
+ </p>
+ <p>
+ <s>Cholesterische Phasen besitzen, im Gegensatz zu smektischen Phasen, keine Konzentrationsschwelle.</s>
+ <s>Da induzierte cholesterische Phasen eine vielfach größere optische Aktivität aufweisen als Substanzmischungen, die ihre optische Aktivität dem Zumischen von chiralen Verbindungen verdanken, können sehr geringe Mengen an optisch aktiver Verbindung nachgewiesen werden.</s>

+ </p>
+ <p>
+ <s>Zur HTP sei angemerkt, dass sie nicht nur das Verdrillungsvermögen eines chiralen Hilfsstoffes, sondern auch die Verdrillbarkeit der nematischen Phase charakterisiert [22].

+ <s>Zusätzlich zur Abhängigkeit vom Betrachtungswinkel und vom Anteil des chiralen Hilfsstoffes ist die Ganghöhe der cholesterischen Helix abhängig von der Temperatur (Thermochromismus) [25, 26].

+ <p>
+ <s>Die Bioaktivierung, Mutagenität und Kanzerogenität von polyzyklischen aromatischen Kohlenwasserstoffen (PAK) ist bereits ausführlich beschrieben worden.</s>
+ <s>Während dabei rein aromatische Verbindungen im Vordergrund standen, gilt das Augenmerk in dieser Arbeit der Bioaktivierung ausgewählter alkylierter PAK (alkPAK).</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>In der Literatur gibt es einige Hinweise dazu, dass die alkPAK durchaus von Bedeutung sind.</s>
+ <s>So kann nach einer Abschätzung von
+ Hoffmann und Wynder (
+ <date instant="false">1971</date>) das kanzerogene Potential eines PAK-haltigen Zigarettenkondensats nur zu 1–3 % mit der Wirkung der enthaltenen rein aromatischen PAK erklärt werden.</s>
+ <s>Weiterhin führen
+ Mumford u. a. (
+ <date instant="false">1995</date>) die fünffach erhöhte Mortalität durch Lungenkrebs in Xuan Wei (China) auf eine fünf bis zehnfach höhere Exposition gegenüber monoalkylierten PAK zurück.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Die Besonderheit der alkPAK ist die Tatsache, dass sie über die Alkylgruppe einen weiteren Angriffspunkt für den Fremdstoffmetabolismus bieten: Nach einer Hydroxylierung und Sulfonierung entstehen benzylische Schwefelsäureester, die unter Umständen sehr reaktiv sind.</s>
+ <s>Bei Pyren ermöglicht beispielsweise erst die Alkylierung eine kanzerogene Aktivierung (Rice u. a.,
+ <date instant="false">1987</date>).</s>

+ <div n="1.1" type="section">
+ <head>
+ <s>1.1 Bildung und Vorkommen von alkylierten polyzyklischenaromatischen Kohlenwasserstoffen</s>
+ </head>
+ <p>
+ <s>Die alkPAK stellen eine Untergruppe der PAK dar.</s>
+ <s>Sie besitzen zusätzlich zu den rein aromatischen PAK, die aus einem aromatischen Ringsystem mit mindestens zwei kondensierten aromatischen Ringen bestehen, noch einen oder mehrere Alkylsubstituenten bzw. Alkanobrücken.</s>
+ <s>Als Beispiele für alkPAK sind 1-Methylpyren (1-MP) und Cyclopenta[mno]benzo[a]pyren (CPBP) in Abb. 1.1 dargestellt.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Allgemein entstehen PAK – reine Aromaten und alkylierte Kongenere – bei der Verbrennung von organischem Material oder durch geochemische Diagenese.</s>
+ <s>Bei Verbrennungstemperaturen >1000 °C überwiegt die Denovo-Synthese aus kleineren Kohlenwasserstoffen, die eine Bildung der rein aromatischen Verbindungen wie Pyren, Chyrsen und Benzo[a]pyren (BP) begünstigt.</s>
+ <s>Optimal für die Entstehung von PAK und insbesondere von alkPAK sind Verbrennungstemperaturen von 660–740 °C (Bay-
+ <pb n="2"/>
+ <gap instant="false"/>ram und Müezzinoglu,
+ <date instant="false">1996</date>).</s>
+ <s>Bei tieferen Temperaturen hat die Zusammensetzung des organischen Ausgangsmaterials einen größeren Einfluss auf die Struktur der entstehenden PAK.</s>
+ <s>Dies gilt insbesondere für die geochemischen Entstehungsprozesse, die über längere Zeiträume bei Temperaturen von 100–200 °C stattfinden (Blumer und Youngblood,
+ <date instant="false">1975</date>).</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Die große strukturelle Vielfalt der PAK im Allgemeinen und der alkPAK im Besonderen bedingt, dass ihr Vorkommen in den wiederum vielfältigen Matrizes wie Lebensmitteln, Konsumgütern und Umweltkompartimenten nur teilweise untersucht ist.</s>
+ <s>Insbesondere für alkPAK liegen hierzu nur relativ wenige Untersuchungen vor.</s>
+ <s>In Tab. 1.1 sind die bisher unveröffentlichten Ergebnisse von Seidel bezüglich der in der vorliegenden Arbeit untersuchten alkPAK zusammengefasst.</s>
+ <s>Neben den in der Tabelle aufgeführten MP und Dimethylpyrenen (DMP) wurden die gleichen Matrizes auch auf 1-,2- und 4-Ethylpyren (EP), 6-Methylanthanthren (MAA) und 6-Ethylanthanthren sowie 6-, 10- und 11-Methylbenzo[a]pyren (MBP) und 6-Ethylbenzo[a]pyren (6-EBP) untersucht.</s>
+ <s>Diese letztgenannten alkPAK konnten – mit Ausnahme von 0,185 µg/kg 6-MBP- und 6-EBP in gegrilltem Schweinesteak – nicht nachgewiesen werden.</s>
+ <s>Das Auftreten von 1-MP, sowie 1- und 2-Methylphenanthren und 2- und 9-Methylanthracen in Grillwürstchen wurde bereits von
+ Larsson u. a. (
+ <date instant="false">1983</date>) nachgewiesen.</s>
+ <s>Der Gehalt an 1-MP variierte bei diesen Untersuchungen je nach Zubereitungsart von nicht nachweisbar bei der Zubereitung in der Bratpfanne bis zu 16,2 µg/kg im Mittel beim Grillen über einem Holzfeuer.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Einige Jahre zuvor beschäftigten sich
+ Snook u. a. (
+ <date instant="false">1978</date>) mit der Analyse von PAK in Zigarettenrauchkondensat.</s>
+ <s>Sie isolierten insgesamt 20 PAK-haltige Fraktionen, wobei fünf Fraktionen ausschließlich mono- und multialkylierte PAK beinhalteten.</s>
+ <s>Neben methylierten und ethylierten Furanen, Indenen, Naphthalenen, Fluorenen, Phen-
+ <pb n="3"/>
+ <gap instant="false"/>anthrenen, Anthracenen und Chrysenen wurden auch DMP nachgewiesen.</s>
+ <s>In einer neueren Arbeit von
+ Guillén u. a. (
+ <date instant="false">2004</date>) wurde die Bedeutung von alkPAK bei der Belastung von Speiseölen mit PAK besonders deutlich.</s>
+ <s>Eine umfangreiche Analyse von 58 ausgewählten alkylierten und nicht alkylierten PAK in Oliven- und Sonnenblumenölen zeigte, dass mehr als 50 % des PAK-Gehalts (140–1470 µg/kg je nach Probe) auf alkylierte Derivate zurückzuführen waren.</s>
+ <s>Naphthalen und seine Alkylderivate waren mit durchschnittlich über 40 % die dominanten Vertreter, aber auch 1-MP wurde mit 0,3 bis 2,7 µg/kg nachgewiesen.</s>
+ <s>PAK mit mehr als vier kondensierten aromatischen Ringen spielten bei den Speiseölen mit Gehalten von zumeist 4 % und weniger eine untergeordnete Rolle.</s>

+ <s>1.2 Humane Exposition</s>
+ </head>
+ <p>
+ <s>Der menschliche Organismus ist gegenüber PAK über verschiedene Absorptionswege und Quellen exponiert.</s>
+ <s>So können PAK inhalativ über Atemluft und Tabakrauch, dermal durch Hautkontakt mit PAK-haltigen Gemischen und oral über Lebensmittel aufgenommen werden.</s>
+ <s>Hinsichtlich der individuellen Hauptbelastungsquellen können Arbeiter, Raucher und nicht beruflich exponierte Nichtraucher unterschieden werden.</s>
+ <s>Die Exposition am Arbeitsplatz findet in der Regel über die Atemluft z.B. bei Verbren-
+ <pb n="4"/>nungsprozessen oder über die Haut z.B. beim Umgang mit Rohöl, Motorenöl oder verschiedenen PAK-haltigen Syntheseprodukten statt.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Der Zigarettenkonsum führt pro Packung gerauchter Zigaretten zur Aufnahme von mehreren µg PAK über die Lunge (
+ Menzie u. a.
+
+ <date instant="false">1992</date>

+
+ <date instant="false">2004</date>

+ <p rend="firstLineIndent">
+ <s>Für beruflich nicht exponierte Nichtraucher sind Lebensmittel mit einem Anteil von über 90 % die bedeutenste PAK-Quelle (

+ Menzie u. a.
+
+ <date instant="false">1992</date>
+ ;
+ Van Rooij u. a.
+
+ <date instant="false">1994</date>
+ ). Bei der Aufnahme über die Nahrung werden die PAK über den Gastrointestinaltrakt absorbiert, wobei die Absorption von der Zusammensetzung der verzehrten Nahrung abhängig zu sein scheint.</s>
+ <s>So wird diskutiert, ob unlösliche Kohlenhydrate die Aufnahme verringern und Fette sie erhöhen (Stavric und Klassen,
+ <date instant="false">1994</date>).</s>
+ <s>Ungeachtet der Bioverfügbarkeit liegt die tägliche Aufnahme an PAK über eine durchschnittliche Ernährung verschiedenen Berechnungen zu Folge bei einigen µg, wie in Tab. 1.2 dargestellt ist.</s>
+ <s>Diese Daten zu aufgenommenen Mengen sind durch die Auswahl der 10 bis 20 quantifizierten PAK-Vertreter limitiert.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Bezüglich der alkPAK zeigen bisher unveröffentlichte Untersuchungen der Arbeitsgruppe Seidel, dass gerade die Monomethylpyrene 1-, 2- und 4-MP in Zigaretten, Grillgut, Motorenölen und auch Umweltproben in ähnlichen Konzentrationen wie BP vorliegen (vgl. Tab. 1.1 und 1.2).</s>
+ <s>Auch Arbeiten von

+ Sopelana (
+ <date instant="false"> 2004 </date>b) und
+ Guillén und Sopelana (
+ <date instant="false"> 2004 </date>a) weisen 1-MP in ähnlichen Größenordnungen wie BP in Lebensmitteln nach.</s>
+ <s>Es kann somit davon ausgegangen werden, dass die humane Belastung mit MP für beruflich nicht exponierte Nichtraucher im Bereich von einigen 100 ng/Tag liegt.</s>
+ <s>Für Raucher und exponierte Arbeiter könnte sie jedoch noch höher liegen, unter Umständen bishin zu wenigen µg.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Eine umfassende Abschätzung der humanen Exposition gegenüber PAK und insbesondere alkPAK ist aufgrund der enormen strukturellen Komplexität nicht möglich.</s>
+ <s>Eine Abschätzung der Exposition gegenüber PAK über BP oder eine kleine Gruppe von 10–20 PAK ist eine praktikable Möglichkeit, führt aber nur zu einer Mindestbelastung, die oftmals die alkPAK außer Acht lässt.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Zur Klärung substanzspezifischer Fragen sowie der Bioverfügbarkeit können Biomarker von einzelnen Vertretern der PAK gemessen werden.</s>

+ <s>1.3 Metabolismus</s>
+ </head>
+ <p>
+ <s>Die Lipophilie der alkPAK – wie auch die der nicht alkylierten PAK – führt ohne Metabolisierung zu einer Anreicherung im Organismus.</s>
+ <s>Diese Anreicherung kann beispielsweise bei Muscheln beobachtet werden (Meador u. a.,
+ <date instant="false">1995</date>).</s>
+ <s>Säugetiere können

B. eine negative Ladung eine aktive oder passive Sekrektion und somit die Ausscheidung aus dem Organismus ermöglicht.</s>
+ <s>Der Fremdstoffmetabolismus untergliedert sich in drei zu betrachtende Phasen: Phase I – Funktionalisierung, Phase II – Konjugation, Phase III – Transport.</s>
+ <s>Im Folgenden wird auf die Biotransformation von alkPAK, den Transport der Metaboliten und die wichtigsten daran beteiligten Proteine eingegangen.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Ein alkPAK bietet für die Biotransformation zwei Angriffsmöglichkeiten: das aromatische Ringsystem und die Alkylgruppe.</s>
+ <s>Der Metabolismus von aromatischen Ringsystemen ist weitgehend aufgeklärt (Hertel u. a.,
+ <date instant="false">1998</date>).</s>
+ <s>Für die in dieser Arbeit verwendeten Substanzen sind das Pyren (Abb. 1.2) und das BP zu betrachten.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>In der Phase I des Fremdstoffmetabolismus findet eine durch Cytochrome P450 (CYP) vermittelte Oxidation der aromatischen Ringsysteme zu entsprechenden Epoxiden, Phenolen und Diolen statt.</s>
+ <s>Die CYP1A1 und 1B1, die über den „aryl hydrocarbon receptor“ (Ah-Rezeptor) auch durch PAK selbst induziert werden können, weisen eine besonders hohe katalytische Aktivität für diese Oxidationen auf.</s>
+ <s>Als sekundäre Metaboliten der Phase I treten Diole, Diolepoxide, Tetrahydrotetrole und Phenolepoxide auf.</s>
+ <s>Die Bildung der Diole aus den entsprechenden Epoxiden wird durch Epoxidhydrolase vermittelt.</s>
+ <s>Diese primären und sekundären Metaboliten der Phase I werden durch Enzyme der Phase II zu Glutathion- (GSH), Glucuronsäure- oder Sulfokonjugaten umgesetzt.</s>
+ <s>Die somit erreichte Zunahme der Hydrophilie hat eine verbesserte Ausscheidung der Fremdstoffe aus dem Organismus zur Folge.</s>
+ <s>Eine Ausnahme stellen die Diolepoxide des BP dar.</s>
+ <s>Diese sind hoch reaktiv und führen zur Bildung von DNA-Addukten, die, wenn sie nicht repariert werden, Mutationen im betroffenen Organismus hervorrufen können.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Zusätzlich zur Transformation des Ringsystems wird bei den alkPAK die Seitenkette durch fremdstoffmetabolisierende Enzyme modifiziert.</s>
+ <s>In der Phase I findet eine CYP-vermittelte Hydroxylierung der Seitenkette statt.</s>
+ <s>Der gebildete benzylische Alkohol ist zum einen ein Substrat für die Alkoholdehydrogenasen (ADH) und Aldehyddehydrogenasen (ALDH) , zum anderen kann er durch die konjugierenden Enzyme der Phase II zum Glucuronid oder Sulfat metabolisiert werden.</s>

+ <hi rend="italic">ori2</hi> auch als Replikationsursprung von Replikons in
+ <hi rend="italic">E. coli</hi> eingebracht werden.</s>
+ <s>In
+ <hi rend="italic">E. coli</hi> kann ein
+ <hi rend="italic">ori2</hi>basiertes Replikon wie synVicII auch ohne
+ <hi rend="italic">crtS</hi> replizieren, während die Deletion der

+ <hi rend="italic">V. cholerae</hi> zu Mutationen in

+ <hi rend="italic">ori2</hi> oder zu Chromosomenfusionen führt ((
+ Val et al.
+
+ <date instant="false">2016</date>
+ ); Kapitel 5.3).</s>
+ <s>Die Integration einer
+ <hi rend="italic">crtS</hi> in das -Chromosom erhöht die Kopienanzahl eines
+ <hi rend="italic">ori2</hi>basierten Minichromosoms relativ zu von 0,31 ± 0,02 auf 0,82 ± 0,13 (Kapitel 5.4).</s>
+ <s>Demnach hat die
+ <hi rend="italic">crtS</hi> in
+ <hi rend="italic">E. coli</hi> ebenfalls einen Einfluss auf die Initiation der DNA-Replikation an
+ <hi rend="italic">ori2</hi>.</s>
+ <s>Warum ist die
+ <hi rend="italic">crtS</hi> in
+ <hi rend="italic">E. coli</hi> mit
+ <hi rend="italic">ori2</hi>basierten Replikons im Gegensatz zu
+ <hi rend="italic">V. cholerae</hi> nicht essentiell?</s>
+ <s>Dies kann verschiedene Ursachen haben.</s>
+ <s>Zum einen könnte es in
+ <hi rend="italic">V. cholerae</hi> einen zusätzlichen negativen Regulator der Initiation der DNA-Replikation an
+ <hi rend="italic">ori2</hi> geben, welcher bei den bisher konstruierten
+ <hi rend="italic">ori2</hi>basierten Minichromosomen in
+ <hi rend="italic">E. coli</hi> fehlt.</s>
+ <s>Zum anderen könnte ein in
+ <hi rend="italic">V. cholerae</hi> nicht vorhandener Faktor in
+ <hi rend="italic">E. coli</hi> die fehlende
+ <hi rend="italic">crtS</hi> ganz oder teilweise komplementieren.</s>
+ <s>Mögliche negative Regulatoren in
+ <hi rend="italic">V. cholerae</hi> wären verschiedene RctB-Bindestellen auf Chr2 außerhalb von
+ <hi rend="italic">ori2</hi>, für die bereits eine Inhibierung der Replikation
+ <hi rend="italic">ori2</hi>-basierter Minichromosomen in
+ <hi rend="italic">E. coli</hi> sowie ein negativer Effekt auf die Kopienanzahl von ori2 in V. cholerae gezeigt werden konnte (
+ Baek and Chattoraj
+
+ <date instant="false">2014</date>
+ ). Interessant wäre, ob eine auf dem E. coli-Chromosom integrierte crtS den negativen Effekt solcher RctB-Bindestellen auf einem
+ <hi rend="italic">ori2</hi>basierten Minichromosom ausgleichen könnte, oder ob die Deletion dieser Bindestellen in
+ <hi rend="italic">V. cholerae</hi> die Deletion der
+ <hi rend="italic">crtS</hi> ermöglicht.</s>
+ <s>Um weitere negative Regulatoren der Initiation an
+ <hi rend="italic">ori2</hi> in
+ <hi rend="italic">V. cholerae</hi> zu finden, könnten Transposon-Mutagenese-Experimente durchgeführt und nach Mutanten mit erhöhter Kopienanzahl von
+ <hi rend="italic">ori2</hi> gesucht oder weitere Stämme untersucht werden, welche eine Deletion der durch eine Mutation kompensieren konnten.</s>
+ <s>Bislang zeigten letztere Stämme jedoch nur Chromosomenfusionen oder Mutationen in rctB und in dessen Expressionsregulation (
+ Val et al.
+
+ <date instant="false">2016</date>
+ ;
+ Ramachandran et al.
+
+ <date instant="false">2018</date>
+ ). Als positiver Regulator der Initiation an ori2 in E. coli wurden bereits die Chaperone DnaK und DnaJ (DnaKJ) gefunden, welche für die Replikation von
+ <hi rend="italic">ori2</hi>basierten Minichromosomen ohne crtS essentiell sind (
+ Jha, Demarre, et al.
+
+ <date instant="false">2012</date>
+ ). Die Integration
+ <pb n="46"/>einer
+ <hi rend="italic">crtS</hi> in
+ <hi rend="italic">E. coli</hi> kann die Deletion von
+ <hi rend="italic">dnaKJ</hi> komplementieren, beide Faktoren scheinen jedoch nicht denselben Wirkmechanismus zu haben (
+ Baek and Chattoraj
+
+ <date instant="false">2014</date>
+ ;
+ Ramachandran et al.
+
+ <date instant="false">2018</date>
+ ). DnaKJ fördern die Monomerisierung von RctB und dessen Bindung an 12- und 39-mere in
+ <hi rend="italic">ori2</hi> sowie an die
+ <hi rend="italic">crtS</hi> durch eine Ummodellierung von RctB (
+ Jha et al.
+
+ <date instant="false">2017</date>
+ ;
+ de Lemos Martins et al.
+
+ <date instant="false">2018</date>
+ ). Zudem scheinen DnaKJ die Oligomerisierung von spezifisch gebundenem RctB auf der DNA in V. cholerae zu verstärken (
+ de Lemos Martins et al.
+
+ <date instant="false">2018</date>
+ ). Im Gegensatz zu
+ <hi rend="italic">E. coli</hi> sind die Chaperone DnaKJ in
+ <hi rend="italic">V. cholerae</hi> essentiell (
+ Chao et al.
+
+ <date instant="false">2013</date>
+ ). Dies scheint auch für den monochromosomalen V. cholerae-Stamm MCH1 zu gelten (
+ Bruhn et al.
+ , unveröffentlichte Daten).</s>
+ <s>Letzteres lässt vermuten, dass DnaKJ auch für andere Abläufe in
+ <hi rend="italic">V. cholerae</hi> außerhalb der Initiation der DNA-Replikation essentiell sind, schließt jedoch eine Abhängigkeit der
+ <hi rend="italic">ori2</hi>basierten DNA-Replikation von DnaKJ wie in
+ <hi rend="italic">E. coli</hi> nicht aus.</s>
+ <s>Somit scheint die Ummodellierung von RctB durch DnaKJ ein weiterer Mechanismus der Regulation der
+ <hi rend="italic">ori2</hi>basierten DNA-Replikation zu sein, der in
+ <hi rend="italic">E. coli</hi> durch einen zusätzlichen positiven oder fehlenden negativen Regulator teilweise ausgeglichen werden kann.</s>
+ <s>Ein positiver Regulator der Initiation der DNA-Replikation an
+ <hi rend="italic">ori2</hi> in
+ <hi rend="italic">E. coli</hi> kann auf verschiedene Arten wirken.</s>
+ <s>Beispielsweise könnte er
+ <hi rend="italic">ori2</hi> direkt beeinflussen oder mit RctB interagieren.</s>
+ <s>Möglich wäre ebenfalls eine indirekte Regulation über Signalmoleküle oder zusätzliche Proteine.</s>
+ <s>Um einen weiteren Interaktionspartner von
+ <hi rend="italic">ori2</hi> in
+ <hi rend="italic">E. coli</hi> zu finden, wäre, wie bereits in Kapitel 6.1.1 beschrieben, eine Methode zur Isolation und Identifizierung spezifischer DNA-Sequenzen und aller an sie gebundener Proteine,
+ <hi rend="italic">in vivo</hi> oder
+ <hi rend="italic">in vitro</hi>, gut geeignet.</s>
+ <s>Zur Identifikation von unbekannten Interaktionspartnern von RctB in
+ <hi rend="italic">E. coli</hi> böte sich eine Methode zur Untersuchung von Protein-Protein-Interaktionen wie ein herkömmlicher Pulldown-Assay oder bakterieller Two-Hybrid an (

+ <s>Wie kann die DNA-Replikation in einem Bakterium mit zwei Chromosomen analysiert werden?</s>
+ <s>In dieser Arbeit wurden je nach Fragestellung vier verschiedene Systeme zur Untersuchung der DNA-Replikation von
+ <hi rend="italic">V. cholerae V. cholerae</hi>verwendet: Bichromosomale und monochromosomale
+ <hi rend="italic">V. cholerae</hi> sowie
+ <hi rend="italic">E. coli</hi> mit einem Replikationsursprung von
+ <hi rend="italic">V. cholerae</hi> auf dem Haupt- oder einem Minichromosom (Abbildung 6.1).</s>
+ <s>Normalerweise verfügt
+ <hi rend="italic">V. cholerae</hi> über zwei Chromosomen unterschiedlicher Größe
+ <pb n="47"/>(Abbildung 6.1A).</s>
+ <s>Es gibt jedoch besondere Ausnahmen, bei denen beide Chromosomen zu einem fusioniert vorliegen (Abbildung 6.1B).</s>
+ <s>Diese Fusion kann entweder natürlich stattfinden oder konstruiert werden und unter Erhalt oder Deletion von
+ <hi rend="italic">ori2</hi> erfolgen (
+ Xie et al.
+
+ <date instant="false">2017</date>
+ ; Val et al. 2012).</s>
+ <s>Da
+ <hi rend="italic">ori2</hi> in Gegenwart von RctB auch in
+ <hi rend="italic">E. coli</hi> funktionsfähig ist, kann
+ <hi rend="italic">oriC</hi> durch
+ <hi rend="italic">ori2</hi> ausgetauscht werden, um ein
+ <hi rend="italic">ori2</hi>basiertes monochromosomales Genom in
+ <hi rend="italic">E. coli</hi> zu erhalten (Abbildung 6.1C).</s>
+ <s>Weiterhin kann
+ <hi rend="italic">ori2</hi> als Basis für Minichromosomen in
+ <hi rend="italic">E. coli</hi> dienen (Abbildung 6.1D), welche ein weitverbreitetes System zur Untersuchung von Replikationsursprüngen darstellen.</s>

+ <hi rend="italic">oriC</hi> schwarz.</s>
+ <s>Minichromosom-DNA ist grau dargestellt.</s>
+ <s>Welches System ist nun für welche Fragestellung sinnvoll?</s>
+ <s>Bei globalen Fragen zur DNA-Replikation in
+ <hi rend="italic">V. cholerae</hi>, welche keine für die DNA-Replikation kritischen Mutationen erfordern, sind bichromosomale
+ <hi rend="italic">V. cholerae</hi> das System der Wahl.</s>
+ <s>So wurde in dieser Arbeit beispielsweise der Effekt der Stringent Response auf die DNA-Replikation in
+ <hi rend="italic">V. cholerae</hi> mit dem bichromosomalen Stamm A1552 untersucht (Kapitel 5.2).</s>
+ <s>Die Zunahme des DNA-Gehalts durch die DNA-Replikation während der SR konnte mittels Durchflusszytometrie gezeigt werden.</s>
+ <s>Da
+ <pb n="48"/>jedoch in den so erhaltenen DNA-Histogrammen nicht zwischen Chr1 und Chr2 unterschieden werden kann, war für die Einzelanalyse der DNA-Replikation beider Chromosomen eine Markerfrequenzanalyse notwendig.</s>
+ <s>Ein weiteres Beispiel für die Verwendung von bichromosomalen
+ <hi rend="italic">V. cholerae</hi> bzw. Vibrionaceae ist die Untersuchung der Frage, ob die Terminationssynchronie in den Vibrionaceae konserviert ist (Kapitel 5.1).</s>
+ <s>Für diese Untersuchung mittels MFA eigen sich nur bichromosomale Vibrionaceae, da die Aufteilung des Genoms auf zwei Chromosomen hier ein essentieller Bestandteil der Fragestellung ist.</s>
+ <s>Eine Deletion von
+ <hi rend="italic">ori2</hi>, beispielsweise zur Beantwortung der Frage, ob die DNA-Replikation während der SR von
+ <hi rend="italic">ori2</hi> abhängt (Kapitel 5.2), ist mit bichromosomalen
+ <hi rend="italic">V. cholerae</hi> nicht möglich.</s>
+ <s>Da die Replikation von Chr2 von
+ <hi rend="italic">ori2</hi> abhängt, und Verlust von Chr2 zum Tod der Zelle führt, ist eine solche Deletion in bichromosomalen V. cholerae letal (
+ Yamaichi, Fogel, and Waldor
+
+ <date instant="false">2007</date>
+ ). Möglich ist sie jedoch in monochromosomalen V. cholerae wie MCH1, da hier das gesamte Genom von
+ <hi rend="italic">ori1</hi> aus repliziert werden kann (
+ Val et al.
+
+ <date instant="false">2012</date>
+ ). Auch Untersuchungen zur Funktion und Regulation von
+ <hi rend="italic">ori2</hi>, welche einen Funktionsverlust von zur Folge haben könnten, sind aus den soeben beschriebenen Gründen mit bichromosomalen nicht möglich.</s>
+ <s>Hier können wieder monochromosomale
+ <hi rend="italic">V. cholerae</hi> eingesetzt werden.</s>
+ <s>So konnte untersucht werden, ob eine Initiation der DNA-Replikation an
+ <hi rend="italic">ori2</hi> stattfindet, wenn die Kopienanzahl der
+ <hi rend="italic">crtS</hi> unter der von
+ <hi rend="italic">ori2</hi> liegt (Kapitel 5.5).</s>
+ <s>Wenn nur einzelne Bereiche von
+ <hi rend="italic">ori2</hi> oder einzelne Regulatoren analysiert werden sollen, ist die Verwendung von basierten Minichromosomen in
+ <hi rend="italic">E. coli</hi> sinnvoll.</s>
+ <s>Diese sind einfach zu konstruieren und ihre Funktionsfähigkeit lässt sich durch ihre Transformierbarkeit in
+ <hi rend="italic">E. coli</hi> bestimmen.</s>
+ <s>Die Kopienanzahl von Minichromosomen verschiedener
+ <hi rend="italic">E. coli</hi>-Stämme lässt sich durch einen einfachen Wachstumstest vergleichen (Kapitel 5.3).</s>
+ <s>Mittels
+ <hi rend="italic">ori2</hi>-basierter Minichromosomen konnte untersucht werden, welche Auswirkungen Manipulationen der essentiellen DnaA-Box in
+ <hi rend="italic">ori2</hi> auf die Funktionsfähigkeit von
+ <hi rend="italic">ori2</hi> haben (Kapitel 5.4).</s>
+ <s>Außerdem konnte durch die Erhöhung der Kopienanzahl von

+ <hi rend="italic">crtS</hi> als auch die Kompatibilität von
+ <hi rend="italic">ori2</hi> und
+ <hi rend="italic">crtS</hi> verschiedener Vibrionaceae analysiert werden (Kapitel 5.1, 5.4, 5.5).</s>
+ <s>Untersuchungen von

+ <hi rend="italic">ori2</hi> von Dam, SeqA oder DnaA, sind nur in
+ <hi rend="italic">E. coli</hi> Stämmen möglich, bei denen

+ <hi rend="italic">ori2</hi>basierten
+ <hi rend="italic">V. cholerae</hi>-Stamms ohne Mutationen in
+ <hi rend="italic">rctB</hi> ist nicht möglich, da die Initiation der DNA-Replikation an
+ <hi rend="italic">ori2</hi> in
+ <hi rend="italic">V. cholerae</hi> von der Verdopplung der abhängt.</s>
+ <s>
+ <pb n="49"/>Die vier beschriebenen Systeme können nicht nur in der Untersuchung der DNA-Replikation von
+ <hi rend="italic">V. cholerae</hi>, sondern auch in der Untersuchung aller anderen
+ <hi rend="italic">chromosome maintenance</hi> -Systeme wie beispielsweise Segregation der Chromosomen, DNA-Reparaturmechanismen, oder Chromosomenfaltung zur Anwendung kommen.</s>
+ <s>Ein weiteres hierfür geeignetes System sind synthetische Chromosomen.</s>
+ <s>Diese Chromosomen sind künstlich hergestellt und können sowohl aus vorgefertigten DNA-Bausteinen assembliert als auch aus natürlichen Chromosomen editiert werden (
+ Gibson et al.
+
+ <date instant="false">2010</date>
+ ;
+ Lajoie et al.
+
+ <date instant="false">2013</date>
+ ). Durch die sinkenden Kosten der DNA-Synthese und verschiedener neuer Methoden der DNA-Assemblierung wie beispielsweise Gibson-Assembly (
+ Gibson et al.
+
+ <date instant="false">2009</date>
+ ), homologe Rekombination in Hefe (Gibson 2009) oder MoClo (
+ Weber et al.
+
+ <date instant="false">2011</date>
+ ;
+ Werner et al.
+
+ <date instant="false">2012</date>
+ ), wird die Neusynthese eines Chromosoms im Vergleich zur Editierung eines bestehenden Chromosoms immer attraktiver (
+ Schindler and Waldminghaus
+
+ <date instant="false">2015</date>
+ ). Eine Verbindung beider Ansätze ist der schrittweise Austausch chromosomaler Bereiche durch neusynthetisierte Abschnitte (
+ Annaluru et al.
+
+ <date instant="false">2014</date>
+ ;
+ Hutchison et al.
+
+ <date instant="false">2016</date>
+ ; Ostrov et al. 2016).</s>
+ <s>Das Überleben einer Zelle, welche allein auf einem primären synthetischen Chromosom basiert, ist unter anderem von diesem Chromosom und somit von der Funktionsfähigkeit aller seiner essentiellen Bestandteile abhängig.</s>
+ <s>Die Verwendung eines sekundären synthetischen Chromosoms, zusätzlich zum nativen primären Chromosom, mildert die Abhängigkeit der Zelle vom synthetischen Chromosom.</s>
+ <s>Getreu dem in der synthetischen Biologie beliebten Zitat
+ <quote>
+ <foreign xml:lang="en">„What I cannot create, I do not understand“</foreign>
+ </quote> (
+ Richard Feynman
+
+ <date instant="false">1988</date>

+ Schindler and Waldminghaus
+
+ <date instant="false">2015</date>
+ ). Aus der Untersuchung synthetischer Chromosomen gewonnene Erkenntnisse können zu ihrer Weiterentwicklung verwendet werden, beispielsweise zur Erzeugung eines synthetischen minimalen Chromosoms (
+ Hutchison et al.
+
+ <date instant="false">2016</date>

+ <s>Einleitung</s>
+ </head>
+ <p>
+ <s>Tropanalkaloide sind sekundäre Pflanzenstoffe, die in Nachtschattengewächsen wie dem Weißen Stechapfel (
+ <hi rend="italic">Datura stramonium)</hi> und dem Schwarzen Bilsenkraut (
+ <hi rend="italic">Hyoscyamus niger)</hi> vorkommen.</s>
+ <s>Ein sporadisches Auftreten findet man auch in einigen Winden, Rotholz, Silberbaum-, Rhizophora-und Wolfsmilchgewächsen sowie Kreuzblütlern.</s>
+ <s>Tropanalkaloide werden in den Wurzeln gebildet und mit dem Flüssigkeitsstrom über die Pflanze verteilt.</s>
+ <s>Die Konzentrationen sind in der Regel am höchsten in den Wurzeln und Samen, wo sie als Schutz gegen Fraßfeinde dienen.</s>
+ <s>Die Gruppe der Tropanalkaloide umfasst mehr als 200 unterschiedliche Alkaloide.</s>
+ <s>Die bekanntesten sind das
+ <pb n="478"/>Hyoscyamin und Scopolamin (L INDENMANN , 1961).</s>
+ <s>Bereits im Mittelalter waren Tropanalkaloide als Arzneimittel bzw. Drogen im Umlauf (M ÜLLER -E BELING et al., 1999).</s>
+ <s>Gelangen Pflanzenbestandteile dieser Arten über das Erntegut in Nahrungs- oder Futtermittel kann es zu Vergiftungssymptomen kommen.</s>
+ <s>Beispielsweise vergifteten sich in Österreich im Jahr 2006 mehrere Personen durch den Verzehr eines mit Stechapfelsamen verunreinigten Hirsegerichts (A GES , 2017).</s>
+ <s>In Deutschland kam es im Jahr 2015 vermehrt zu Rückrufaktionen des Handels, als bei der Untersuchung verschiedener Getreideprodukte, insbesondere Rispenhirse-Produkte (
+ <hi rend="italic">Panicum miliaceum</hi>)vielfach erhöhte Tropanalkaloidgehalte ermittelt wurden (B FR , 2013).</s>
+ <s>Generell sind Sommerungen wie Hirse-Arten, Mais, Buchweizen und Sonnenblumen mehr von der Problematik betroffen als Winterungen, da die tropanalkaloidhaltigen Unkräuter wärmeliebend sind und erst relativ spät im Jahr auflaufen.</s>
+ <s>Samen tropanalkaloidhaltiger Unkräuter sind nicht immer gut aus dem Erntegut heraus zu reinigen, hinzu kommt eine mögliche Kontamination durch andere Pflanzenteile wie Blattstückchen oder Pflanzensäfte (S ÖCHTING , 2016).</s>
+ <s>In Deutschland sind der Weiße Stechapfel (
+ <hi rend="italic">Datura stramonium</hi>)und das Schwarze Bilsenkraut (
+ <hi rend="italic">Hyoscyamus niger</hi>)die wichtigsten tropanalkaloidhaltigen Acker-Unkräuter.</s>
+ <s>Laut M EHRTENS (2005) liegen die Stetigkeiten für den weißen Stechapfel in Maisschlägen bei 0,3 % und für das Schwarze Bilsenkraut bei 0,4 %.</s>
+ <s>Somit ist ein Auftreten der Arten in Kulturpflanzenbeständen zwar weniger häufig festzustellen, kann aber nach eigenen Erfahrungen schlagspezifisch massiv sein.</s>
+ <s>Die Bedeutung von verunreinigten Futter- oder Nahrungsmitteln mit Tropanalkaloiden könnte zunehmen, da sich durch Klimaveränderung und veränderte Anbaustrukturen die betroffenen tropanalkaloidhaltigen Arten auch in Deutschland weiter ausbreiten werden.</s>
+ <s>Am JKI wurden mit mehreren tropanalkaloidhaltigen Unkräutern Keimtests und Untersuchungen zu herbiziden Kontrollmöglichkeiten durchgeführt, um weitere Erfahrungen mit diesen Arten zu gewinnen.</s>

+ <p>
+ <s>Keimversuch im Labor Die Keimtests im Labor wurden auf Nährlösungsbasis durchgeführt.</s>
+ <s>Bei der verwendeten Nährlösung handelte es sich um eine 2,0 mM Ca (NO 3 )2 + 0,1%ige Previcur Energy Lösung, um die Keimung anzuregen und Pilzwachstum zu verhindern.</s>
+ <s>Zur Ermittlung der Keimfähigkeit sollten die Samen bei definierten Temperaturbedingungen in Petrischalen mittels Nährlösung zur Keimung gebracht werden.</s>
+ <s>Zur Temperaturregulierung wurden Klimaschränke der Firma Rumed eingesetzt.</s>
+ <s>Wie in der Einleitung erwähnt, sollte der Temperaturbereich für eine optimale Keimung ermittelt werden.</s>
+ <s>Jede Petrischale wurde zuvor mit 2 Filterpapieren ausgelegt, dann wurden 5 ml der oben beschriebenen Nährlösung ausgebracht.</s>
+ <s>Nachfolgend wurden jeweils 25 Samen der 5 Arten (Tab. 1) gleichmäßig in den Petrischalen verteilt.</s>
+ <s>Das Saatgut stammte aus dem Jahr 2016 aus eigener Vermehrung.</s>
+ <s>Je nach Variante mussten die Petrischalen täglich oder in Abstand von mehreren Tagen nachgewässert werden, damit die Samen nicht austrockneten.</s>
+ <s>Im Klimaschrank wurden drei Temperaturvarianten für die Keimtests eingestellt und zwar 1. 15/10 °C Wechseltemperatur 2. 20/10 o C Wechseltemperatur 3. 25/10 ° C Wechseltemperatur Die Beleuchtung war 14 Stunden hell und 10 Stunden dunkel eingestellt.</s>
+ <s>Die Versuche wurden wöchentlich bonitiert und galten als beendet, wenn nach zwei Zählterminen keine weitere Keimung mehr beobachtet werden konnte.</s>
+ <s>
+ <pb n="479"/>
+ <gap instant="false"/>Die gekeimten Samen wurden gezählt und mit einer Pinzette aus der Petrischale entfernt.</s>
+ <s>Als gekeimt galten jene Samen, bei denen die gesunde Keimwurzel deutlich erkennbar war.</s>

+ <s>Keimtest im Labor Bevor man die Ergebnisse des Keimtests genauer betrachtet, gilt es festzustellen, dass die Arten
+ <hi rend="italic">Datura ferox</hi> und
+ <hi rend="italic">Datura innoxia</hi> in Deutschland nur sporadisch auftreten und als Ackerunkräuter keine Bedeutung besitzen.</s>
+ <s>Da sie in den Versuchen deutlich schlechter keimten als
+ <hi rend="italic">Datura stramonium</hi> und auch noch wärmeliebender sind, ist auf absehbare Zeit auch nicht mit diesen Arten als ernstzunehmendes Ackerunkraut zu rechnen.</s>
+ <s>In anderen Regionen der Welt spielen die Arten dagegen sehr wohl eine Rolle.</s>
+ <s>Der genetisch fixierte Zeitpunkt einer Unkrautkeimung wird je nach Art durch Umwelteinflüsse mehr oder weniger stark beeinflusst.</s>
+ <s>In dem oben durchgeführten Keimtest wurde frisches Saatgut verwendet und die Keimung sollte unter einem Temperaturwechsel bei ebenfalls wechselnden Lichtverhältnissen stattfinden.</s>
+ <s>Die bei uns häufige Stechapfelart
+ <hi rend="italic">Datura stramonium</hi>sprach gut auf diese Bedingungen an und zeigte schon bei 15 °C eine gute Keimfähigkeit, was für eine weiteres Verbreitungspotential dieser Art in Deutschland spricht.</s>
+ <s>Die extrem schlechte Keimfähigkeit von
+ <hi rend="italic">Datura ferox</hi> könnte auf eine ausgeprägtere Samenruhe zurückzuführen sein im Vergleich zu den anderen beiden Arten.</s>
+ <s>Vermutlich braucht der Embryo im Samenkorn wesentlich
+ <pb n="484"/>längere Entwicklungszeiten oder spezielle Keimhemmstoffe müssen deaktiviert werden.</s>
+ <s>Ähnliches könnte für die bei uns weitverbreitete Art
+ <hi rend="italic">Hyoscyamus niger</hi> gelten
+ <hi rend="italic">,</hi> die partout keine Keimlinge hervorbrachte.</s>
+ <s>Eventuell benötigen die Samen dieser einheimischen Art eine Frostperiode, um die Keimruhe zu brechen.</s>
+ <s>Gegensätzlich dazu keimte die bei uns selten auftretende und eher in südeuropäischen Klimaten verbreite Art
+ <hi rend="italic">Hyoscyamus albus</hi> bei 25 °C nahezu vollständig.</s>
+ <s>Die Wärmebedürftigkeit dieser Art zeigt sich aber durch eine reduzierte Keimung der Samen bei 15 °C.</s>
+ <s>Die nur bei hohen Temperaturen gleichmäßige und gute Keimung der hier geprüften Arten zeigt, dass in Kulturpflanzenbeständen in Deutschland damit gerechnet werden muss, dass die übliche Herbizidapplikation vor der Keimung der hier untersuchten Arten durchgeführt wird und somit keine ausreichende Bekämpfung mehr gewährleistet werden kann.</s>

+ <s>Ohne berauschende Getränke etwa sind die dionysischen Mysterien nicht denkbar, aus denen sich die griechische Tragödie entwickelt, und das Lob des Weins als Gegenstand der Dichtung gehört zum festen Bestand der Lyrik seit dem ionischen Dichter Anakreon, dessen Tod in hohem Alter die Legende darauf zurückführt, daß er sich an einer vertrockneten Weinbeere verschluckte und erstickte.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Die phantasiebefeuernde Wirkung des Alkohols, und das heißt zunächst vor allem des Weins, ist ein Topos der Dichtung und der ihr eingeschriebenen Poetik, wie ein Blick in einschlägige Anthologien zeigt; beispielhaft sei verwiesen auf die Zitate am Anfang des von Hans-Jörg Koch besorgten Buchs über die Muse Wein sowie auf das von Curt Sigmar Gutkind und Karl Wolfskehl herausgegebene Buch vom Wein, für das sich auch Gerhart Hauptmann interessierte und das eine Fülle von Beispielen für die Verehrung des Weins (nebst gelegentlichen Warnungen vor seiner die Sinne betörenden Wirkung) bietet.</s>
+ <s>Wesentliche Motive finden sich in nuce in den Auszügen aus Yorick’s Meditations upon Various Interesting and Important Subjects, die Koch seinem Buch als Motto voranstellt:
+ <gap instant="false"/> Inzwischen hat sich ein ganzer Fundus an griffigen Bildern für die Bedeutung von Alkohol und Drogen überhaupt als »Treibstoff« für Literatur- und Kunstproduktion entwickelt.</s>
+ <s>»Potente Gehirne aber stärken sich nicht durch Milch, sondern durch Alkaloide«, erklärte Gottfried Benn 1943 in Provoziertes Leben apodiktisch; von der »Muse aus der Flasche« spricht Alexander Kupfer in seiner
+ <pb n="10"/>1996 publizierten Studie Die Künstlichen Paradiese, und Michael Krüger bringt den Zusammenhang von Alkoholrausch und Kunst gar auf die knappe Formel: »Wer schreibt, trinkt auch. [ . . . ] Ein Alkoholnebel liegt über der Weltliteratur.« </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Gemessen an mehr als zwei Jahrtausenden Lob des Weins ist die Darstellung der dunklen Seiten des Alkohols in der Literatur deutlich jüngeren Datums.</s>
+ <s>Erst die spätmittelalterliche Literatur thematisiert gelegentlich das übermäßige Trinken an den Höfen, schließlich entsteht eine satirische Trinkliteratur, die im 16. Jahrhundert mit Johann Fischarts »grotesker Trunkenlitanei im 8. Gargantuakapitel ihren Höhepunkt erreichte«.</s>
+ <s>Dabei zeigen die ausführlichen Schilderungen von Trinkexzessen selbst in denjenigen Schriften, die schon im Kontext des klerikalen Kampfs »Wider den Saufteufel« (Matthäus Friderich, 1551) stehen, bereits jene Ambivalenz von Ablehnung und Faszination, die den Verlauf der Kulturgeschichte des Alkohols fortan prägen wird.</s>
+ <s>Mit Beginn der Aufklärung gerät der Alkoholrausch dann in Widerspruch zum Ideal der nüchternen Vernunft, gerade auch in Bezug auf die künstlerische Produktion.</s>
+ <s>Nach Alexander Kupfer hielt beispielsweise »ein Aufklärer wie Kant die Vorstellung eines positiven Bezuges zwischen Rausch und Kreativität für baren Unsinn«.</s>
+ <s>Selbst Goethe, dessen kontinuierlich hoher Weinverbrauch bekannt ist, erklärte gegenüber Eckermann, Schiller habe »nie viel getrunken«, doch schon der mäßige Alkoholkonsum sei der Gesundheit des Kollegen abträglich und dessen »Produktionen selbst schädlich« gewesen.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Bedeutende Breitenwirkung erreichte das Postulat eines künstlerischen Nutzens von Drogen vor allem seit Beginn der (europäischen) Romantik und prägt seitdem auch den Außenblick auf künstlerisches Produzieren.</s>
+ <s>Am Ende des 19. Jahrhunderts kann die Psychiatrie auf so viele alkohol- und drogengeschädigte Künstler zurückblicken, daß die Verbindung von Genie und Krankheit zum Topos geworden ist.</s>
+ <s>In den 1930 verfaßten Essays Das Genieproblem und Genie und Gesundheit geht Gottfried Benn, Dichter mit dem Brotberuf des Arztes, darauf ein.</s>
+ <s>Goethes täglichen Konsum von ein bis zwei Flaschen Wein läßt er als »bürgerliche Flüssigkeitsaufnahme« durchgehen, um dann aber nach Wilhelm Lange-Eichbaums wirkmächtigem Buch Genie – Irrsinn und Ruhm eine lange Reihe von »genialen Persönlichkeiten« aufzuzählen, die das »Trinken mit der erklärten Absicht des
+ <pb n="11"/>Rauschs« pflegten und von denen ein erheblicher Teil im 19. Jahrhundert gewirkt hat:
+ <gap instant="false"/> Als der Psychiater C. F. van Vleuten 1906 eine Umfrage zum Verhältnis von dichterischer Arbeit und Alkohol unter 150 Schriftstellern durchführte und die Antworten im Literarischen Echo publizierte, begründete er die Wahl seines Untersuchungsgegenstandes allerdings nicht mit einer besonderen Anfälligkeit dieser Berufsgruppe für Alkoholabhängigkeit, sondern mit deren Neigung zu intensiver »Selbstbeobachtung«.</s>
+ <s>Daß Alkoholismus im Englischen als »writer’s disease« bezeichnet werde, scheint erst eine Folge des im letzten Drittel des 20. Jahrhunderts verstärkten Interesses von Psychiatrie und Literaturwissenschaft am Thema »Alkohol und Autor« zu sein.</s>
+ <s>So heißt es in Tom Dardis’ Studie über die ›durstige Muse‹ der amerikanischen Schriftsteller: »The presence of the disease in so many of our notable writers surely makes it appear that alcoholism is the American writer’s disease.«
+ <pb n="12"/>
+ </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Kein Zufall ist es daher wohl auch, daß sich vor allem Amerikanistik und Anglistik des Themas angenommen haben, zumal sich Alkoholismus einer Bestandsaufnahme des amerikanischen Psychiaters und Anglisten Donald W. Goodwin zufolge unter Schriftstellern des höchsten Niveaus als wahre Epidemie erweise:
+ <gap instant="false"/> Die Lust an der Pointe und ein vorrangig psychiatrisches Interesse führen Goodwin die Feder, der sich deshalb überwiegend auf biographische Zeugnisse stützt und die Werke der betrachteten Autoren hauptsächlich als Quelle für deren Pathographie heranzieht.</s>
+ <s>Aus literaturwissenschaftlicher Sicht kritisiert Thomas B. Gilmore diesen Ansatz; auch die Biographie eines dem Alkohol zugeneigten Autors könne erst aufgrund seines Werks allgemeineres Interesse beanspruchen, und biographische Betrachtung, die das Trinken nicht in Beziehung zum Werk setze, bleibe für die Literaturgeschichte belanglos, bestenfalls anekdotisch.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Entsprechend betont James Nicholls, daß das Trinken ein mächtiges erzählerisches Mittel sei (»Drink is, without doubt, a powerful narrative device«), und
+ <pb n="13"/>weist auf die doppelte Perspektive hin, unter der man literarische Gestaltungen des Trinkens betrachten könne: als Funktion des Alkohols in der Fiktion, und wie die Fiktion das real existierende Trinken darstelle (»how alcohol functions within fictions as about how fictions represent drink«).</s>
+ <s>Noch weiter auf den Zusammenhang von Gegenstand und Form zugespitzt: »Drunkenness can be both the subject of literary representation and a phenomenological condition that informs the very nature of literature itself.« </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Vor »allzuviel Vollmundigkeit« beim »Wechselspiel zwischen Spirituellem und Spirituösem« warnt der Anglist und Schriftsteller Ulrich Horstmann, der vier »mögliche Interaktionszonen zwischen Alkohol und Literatur« unterscheidet.</s>
+ <s>Darstellungen von Trinkern in der Literatur gehörten häufig zum »Stereotypenarsenal« und ließen daher nicht notwendigerweise auf das Verhältnis ihrer Autoren zum Alkohol schließen.</s>
+ <s>Von geringem Interesse für das Thema seien auch jene Autoren, deren Alkoholabhängigkeit der Öffentlichkeit unbekannt sei und die »jede direkte Aussage zum Zusammenhang von Trinkzwang und Schreibimpuls verweigern«.</s>
+ <s>Den hohen Anteil an Trinkern in der modernen Kunst erklärt Horstmann als eine »seltsame Überbietungslogik« seit dem späten 19. Jahrhundert, die in Analogie zu den stereotypen Trinkerdarstellungen in der Literatur das Klischee des Alkoholismus als Grundlage der Kunst und den »Mythos der Spiegelsymmetrie von Abusus und Originalität« kultiviere.</s>
+ <s>Übrig blieben jene wenigen »Kunsttrinker«, bei denen der Alkohol wirklich »vom Störfaktor zur Produktivkraft, von der lähmenden Droge zum Elixier« werde und »der Autor nicht mehr hin- und hergerissen ist zwischen Stupor und Ausnüchterung, Konzentration und Konzentrat, sondern synergetisch mit dem Genußgift arbeitet, statt dagegen anzukämpfen«; als Beispiele führt Horstmann E. T. A. Hoffmann, Jack London, Joseph Roth, Malcolm Lowry und Wenedikt Jerofejew an.</s>
+ <s>Die vorliegende Studie verdankt ihre Anregung zwar teilweise der Lektüre von Goodwins biographischen Skizzen, setzt jedoch mit der Konzentration auf einen einzigen Autor und sein literarisches Werk einen anderen Schwerpunkt.</s>
+ <s>Die Bedeutung des Alkohols in Werk und Leben Gerhart Hauptmanns ist nicht ganz
+ <pb n="14"/>unbekannt, jedoch sind beide Aspekte meist voneinander unabhängig betrachtet worden.</s>
+ <s>Zeitgenossen und Biographen haben die Trinkfreudigkeit dieses Autors durchaus zur Kenntnis genommen.</s>
+ <s>In den dreißig Anekdoten um Hauptmann, die Gerhard Eckert zusammengetragen hat, spielt allein in sechs der Alkohol eine Rolle; eine von ihnen beginnt mit der Bemerkung, wenn »eine Tatsache aus dem Alltag« des Dichters »unzweideutig erhärtet« sei, dann »seine Neigung für den Genuß von Burgunder.« </s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Am Anfang seiner Laufbahn als naturalistischer Schriftsteller steht Hauptmann jedoch nicht in der Tradition der durch Alkohol und andere Rauschdrogen inspirierten romantischen und nachromantischen Dichter, sondern wird zum Mitbegründer der deutschen »Fuselpoesie« in einem kritischen Sinne.</s>
+ <s>Historischer Hintergrund ist die Alkoholfrage als soziales Problem, das etwa gleichzeitig mit der Aufwertung des Rauschs als Inspirationsquelle aufkam, nachdem sich bis Mitte des 19. Jahrhunderts die sogenannte »Branntweinpest« entwickelt hatte, als Kollateralschaden der Industrialisierung, begünstigt durch die Möglichkeit, Alkohol aus billigen Kartoffeln statt aus teurem Getreide zu gewinnen.</s>
+ <s>Die Literatur des europäischen Naturalismus reagierte auf die sozialen Verwerfungen und griff die Alkoholfrage als Motiv auf; prominentestes Beispiel ist Émile Zolas 1877 erschienener Roman L’Assommoir (dt. Der Totschläger).</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Zu Recht hat sich die Hauptmann-Philologie daher überwiegend mit der Thematisierung des Alkohols im Werk des Dichters beschäftigt, vor allem in Vor Sonnenaufgang und den frühen naturalistischen Dramen.</s>
+ <s>Besondere Erwähnung
+ <pb n="15"/>verdient Hermann Barnstorffs 1938 erschienenes Buch, weil es die ausführlichste Aufzählung von Vorkommen des Alkoholmotivs in Hauptmanns bis dahin veröffentlichtem Werk enthält.</s>
+ <s>Der Autor geht ein auf die zahlreichen Gründe für das Trinken, auf Folgen des Trinkens und durch den Alkohol verursachte Schäden sowie des Dichters Fähigkeit, physiologische Folgen des Alkohols exakt zu schildern.</s>
+ <s>Hauptmann wolle durch »andauernde Hinweise auf die bösen Folgen des Trinkens [ . . . ] die Menschen aufklären, warnen und bessern« und zeige »großes Mitgefühl für die Menschen, die unter Trunksucht leiden«.</s>
+ <s>Es sei aber auch eine Wandlung in seiner »Einstellung zur Alkoholfrage« zu erkennen: Sittliche Entrüstung und Mitgefühl ließen im Alterswerk nach, und soviel in den späten Werken Das Meerwunder, Hamlet in Wittenberg und Im Wirbel der Berufung auch getrunken werde: »nie wird daraus eine Anklage gemacht«.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Als besonders aufschlußreich erweist sich der Fall Hauptmann durch die Verbindung von Alkohol und Eugenik zu einem Motivkomplex.</s>
+ <s>Der von Francis Galton 1883 eingeführte Begriff ›Eugenik‹ wird hier verwendet im allgemeinen Sinne einer Erbgesundheitspflege, die erst durch die Darwinsche Entwicklungslehre möglich wurde: als Versuch, »durch geschickte Ausnutzung der Gesetzmäßigkeiten der natürlichen Auslese« die Evolution der Menschheit gezielt zu beeinflussen.</s>
+ <s>Hauptmann selbst dürfte eher die spätestens 1895 von seinem Jugendfreund Alfred Ploetz (1860–1940) geprägte Eindeutschung der Eugenik als »Rassenhygiene« gekannt haben.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Die Eugeniker gingen von einer degenerierenden Wirkung des Alkohols aus; der Motivkomplex von Alkohol und Eugenik ist also bereits in der außerliterarischen Wirklichkeit angelegt.</s>
+ <s>Nur in Hauptmanns erstem sozialen Drama, Vor Sonnenaufgang, trägt dieser Motivkomplex ein ganzes Werk, auf einzelne Motive
+ <pb n="16"/>aber kommt der Dichter wiederholt in späteren Texten zurück.</s>
+ <s>Dafür lassen sich verschiedene Gründe identifizieren: Als Sohn eines Gastwirts hatte er genaue Kenntnis von Trinkgewohnheiten, Trinkertypen sowie individuellen und sozialen Folgen des Alkoholge- und -mißbrauchs; dies gehörte zum Fundus für seine realistischen Werke.</s>
+ <s>Aufgrund der eigenen Vorliebe für alkoholische Getränke, deren kreativitätsfördernde Wirkung er häufig betont hat, währte eine kurzzeitige Faszination für die Abstinenzbewegung nicht lange und wich einer lebenslangen, zunehmend kritischen Auseinandersetzung mit den Alkoholgegnern, die ihren Höhepunkt mit dem 1941 als Reaktion auf die ›Euthanasie‹ entstandenen Märchen erreicht.</s>
+ <s>In Alfred Ploetz sah der Dichter Abstinenzideologie und Eugenik vereint, daher wird der Freund für ihn zum Inbegriff des nüchternen, materialistischen Wissenschaftlers, dessen Methoden nicht geeignet seien, die Hervorbringungen des Geistes (durchaus in doppelter Bedeutung), insbesondere die Werke der Dichtkunst, zu erfassen.</s>
+ </p>
+ <p rend="firstLineIndent">
+ <s>Damit ist der Spannungsbogen beschrieben, den diese Studie umreißt, als deren Themenstellung der Motivkomplex von Alkohol und Eugenik gelten kann, ohne jedoch in der Motivuntersuchung einen Selbstzweck zu sehen.</s>
+ <s>Ziel ist es vielmehr, Erkenntnisse über Hauptmanns künstlerisches Selbstverständnis und dessen Implikationen für seine Selbstinszenierung wie auch seine öffentliche Wahrnehmung zu gewinnen (so ungefähr ließe sich die übergeordnete Problemstellung formulieren).</s>
+ <s>›Selbstverständnis‹ schließt hier ästhetische oder poetische Positionen wie auch das gesellschaftliche Rollenverständnis des Dichters ein.</s>
+ <s>Die Problemstellung hat im weiteren Sinne also eine literatursoziologische Dimension, die jedoch nicht explizit, etwa als Methode, einbezogen wird.</s>
+ <s>Im Zentrum der Betrachtung steht Hauptmanns Werk (einschließlich privater Aufzeichnungen), in dem sich das Selbstverständnis des Dichters widerspiegelt.</s>

+ <head>BALANCE ZWISCHEN OFFENHEIT UND RAHMENSETZUNG</head>
+ <p>
+ <s>Gemeinsames Planen und Entscheiden auf Augenhöhe stellt das Herzstück der Partizipation dar.</s>
+ <s>Auch bei der Entstehung von neuen Gemeinschaftsgärten wäre der Idealzustand, wenn alle Betroffenen in Stadt oder Quartier das Vorgehen demokratisch abstimmen und in einem offenen Prozess Flächen auswählen und neue Gärten planen.</s>
+ <s>Die Erfahrungen aus GeSiGa zeigen jedoch, dass die Resonanz auf abstrakte Planungs- und Gesprächsveranstaltungen zu Beginn eher gering ist.</s>
+ <s>Dies gilt sowohl für die Einbeziehung der Garteninteressierten aus der Nachbarschaft als auch für den strategischen Dialog mit Multiplikatoren.</s>
+ </p>
+ <div type="subsection">
+ <head>
+ <s>Einbeziehung von interessierten BürgerInnen</s>
+ </head>
+ <p>
+ <s>Der überwiegende Teil der BürgerInnen, die auf die Ansprache reagieren, bringt eine hohe Motivation zum praktischen Handeln mit sich und kommt mit der Erwartung zu Veranstaltungen, dass dort etwas geschieht.</s>
+ <s>Nach den Erfahrungen in GeSiGa stehen hierbei zu Beginn zwei Fragen im Mittelpunkt: ‚Wo soll der Garten entstehen?‘ ‚Wie können wir mitmachen und diesen ausgestalten?‘ Daher empfiehlt es sich, den Prozess zu Beginn nicht zu offen zu gestalten, sondern einen klaren Rahmen vorzugeben.</s>
+ <s>Dies erleichtert den Einstieg und eröffnet Räume für bürgerliches Engagement.</s>
+ <s>Wie schon während der Analysephase gilt: Der Stein soll ins Rollen gebracht werden.</s>
+ <s>Legen Sie das Augenmerk also nicht zu stark auf das Planen und Aushandeln im Vorhinein.</s>
+ <s>Werden Sie stattdessen früh konkret und stellen Sie eine Fläche zur Verfügung, die als Planungsgrundlage dient, damit schnell in die gemeinschaftliche Umsetzung übergegangen werden kann.</s>
+ <s>Aufwendige Beteiligungsverfahren, in deren Verlauf die Wünsche der BürgerInnen eingeholt und gemeinsam mit der Politik Leitbilder oder Rahmensetzungen ausgehandelt werden, sind eher für die Verstetigung der Aktivierung zielführend (siehe Schritt 5).</s>
+ </p>
+ </div>
+ <div type="subsection">
+ <head>
+ <s>Strategischer Dialog mit Multiplikatoren</s>
+ </head>
+ <p>
+ <s>Für eine langfristige Perspektive ist es vielversprechend, soziale Träger, Kulturvereine und Interessensgruppen ins Gespräch zu holen und mit ihnen eine gemeinsame Strategie zur Förderung von Gemeinschaftsgärten zu entwickeln.</s>
+ <s>Urbanes Gärtnern stellt für die meisten Akteure jedoch lediglich einen interessanten Nebenschauplatz dar, der auf der Prioritätenliste nicht weit oben steht.</s>
+ <s>Organisationen, die das Gärtnern unterstützen wollen, wünschen sich konkrete Gartenprojekte an denen sie sich beteiligen oder auf die sie hinweisen können.</s>
+ <s>Die Erfahrung aus GeSiGa zeigt, dass für strategische Gespräche oder einen eigenen Arbeitskreis zum Urbanen Gärtnern daher häufig die Zeit fehlt.</s>
+ <s>Um mit Akteuren trotzdem strategische Planungen voranzutreiben, empfehlen wir daher bestehende Kooperationsnetzwerke zu nutzen, bspw. Arbeitskreise zur Integrationsarbeit oder anderen sozialen Themen, oder Nachbarschaftsgremien in Quartieren.</s>

+ <s>BÜRGERWERKSTÄTTEN & VERANSTALTUNGEN</s>
+ </head>
+ <p>
+ <s>Bürgerwerkstätten sind wichtige Kontaktpunkte und Vernetzungsforen während der Aktivierung.</s>
+ <s>Hier lernen sich interessierte BürgerInnen aus der Nachbarschaft kennen und treffen auf die VertreterInnen von Unterstützerorganisationen und Verwaltung.</s>
+ <s>
+ <hi rend="italic">Informations- und Vernetzungsveranstaltungen</hi>, beispielsweise mit Multiplikatoren organisiert, sind zum Auftakt der Aktivierung ein guter Weg um viele Leute zu erreichen.</s>
+ <s>Ein kurzer Vortrag als Impuls und offene Diskussionsrunden bieten die Gelegenheit, sich mit dem neuen Thema zu beschäftigen.</s>
+ <s>Für das Ziel, neue Gärten entstehen zu lassen, wurden gute Erfahrungen mit niederschwelligen
+ <hi rend="italic">Planungswerkstätten</hi> gemacht.</s>
+ <s>Diese zeichnen sich dadurch aus, dass in informellem Rahmen und auf Augenhöhe anhand einer konkreten Fläche das weitere Vorgehen zum Gartenbau besprochen wird.</s>
+ <s>Bei der Vorbereitung sollte auch bedacht werden, dass Ort und Zielgruppe zusammenpassen: Wenn es beispielsweise um die Pla-
+ <pb break="no" n="22"/>nung eines Schulgartens geht, kann die Bürgerwerkstatt direkt in der Schule stattfinden und mit einer Flächenbegehung verbunden werden.</s>
+ <s>Weitere interessante Orte sind Gaststätten, Nachbarschaftszentren oder die Räumlichkeiten von lokalen Akteuren.</s>
+ <s>Planungswerkstätten sollten so praxisnah wie möglich sein und den BürgerInnen jederzeit das Gefühl geben, dass etwas passiert und nicht zerredet wird.</s>
+ <s>Auf aufwändige Moderationsmethoden kann daher weitestgehend verzichtet werden.</s>
+ <s>Essentiell ist eine erfahrene Gesprächsleitung, die dafür sorgt, dass alle Stimmen gehört werden und der rote Faden verfolgt wird.</s>
+ <s>Wichtig ist zudem, dass zeitnah mit der Umsetzung des Gartens begonnen werden kann.</s>
+ <s>Nichts lähmt das Engagement mehr, als lange, unfreiwillige Wartezeiten.</s>
+ <s>Stärker strukturierte
+ <hi rend="italic">Beteiligungsveranstaltungen</hi> eignen sich dann, wenn Ideen und Wünsche aus der Bürgerschaft gesammelt und gemeinsame Ziele definiert werden sollen.</s>
+ <s>Moderationsmethoden, wie Kartenabfragen oder Visualisierungen können dann ein wichtiges Element sein.</s>
+ <s>Dies bietet sich insbesondere an, wenn neue Flächen identifiziert oder langfristige Perspektiven ausgelotet werden sollen.</s>
+ <s>Ein derartiges Vorgehen funktioniert allerdings erfahrungsgemäß nur, wenn das Thema unter den BürgerInnen bereits bekannt ist und ein öffentliches Interesse besteht, sich mit solchen eher abstrakten Fragen auseinanderzusetzen.</s>

+ <s>LEITFRAGEN ZUR GARTENPLANUNG</s>
+ </head>
+ <p>
+ <s>Gemeinschaftsgärten können weder am Reißbrett geplant, noch strategisch gesteuert werden.</s>
+ <s>Ein kleinschrittiges Vorgehen bewahrt Offenheit und sorgt dafür, dass das Projekt lebendig und für alle Beteiligten nachvollziehbar bleibt.</s>
+ <s>Gemeinschaftsgärten sind Experimentierräume, die organisch wachsen und sich durch das Engagement der Beteiligten entwickeln.</s>
+ <s>Dass dabei Widersprüche auftreten und gewisse Vorstellungen unvereinbar erscheinen, liegt in der Natur der Sache.</s>
+ <s>Diese Unterschiedlichkeiten gilt es zusammenzuführen und sorgfältig zu integrieren.</s>
+ <s>Die partizipative Planung eines Gemeinschaftsgartens mit interessierten BürgerInnen sollte daher grundsätzlich als ergebnisoffener Prozess verstanden werden.</s>
+ <s>Die folgenden Fragen bieten Orientierung und können dabei helfen der Gartenplanung eine Richtschnur zu geben.</s>
+ </p>
+ <div type="subsection">
+ <head>
+ <s>An welche Zielgruppe richtet sich der Garten?</s>
+ </head>
+ <p>
+ <s>Ein Nachbarschaftsgarten richtet sich an alle BewohnerInnen des Quartiers, in einem Schulgarten hingegen liegt der Fokus eher auf den Kindern und ihren Eltern.</s>
+ <s>Wird ein Garten mit der Sozialberatung oder der Tafel gegründet, so sind Erwerbslose besonders im Blick.</s>
+ <s>Entsteht in Kooperation mit einer Wohnbaugesellschaft ein Garten in einem Hinterhof, so ist er automatisch weniger offen angelegt, als ein von der Straße sichtbarer Garten.</s>
+ <s>Wenn der Garten eine interkulturelle Philosophie verfolgen soll, so steht der kulturelle Austausch im Vordergrund.</s>
+ <s>Egal welche Richtung der Garten nehmen soll, um die Erwartungen der Beteiligten zu klären, ist es sinnvoll sich auf eine grobe Richtung festzulegen: Beispielsweise „ein offener Garten für die ganze Stadt“, „ein interkultureller Frauengarten“, „ein Schulgarten“, oder „ein Selbstversorgergarten für die Anwohner des Blocks“.</s>
+ <s>Wichtig ist es, sich bewusst zu bleiben, dass zunächst nur die ‚Keimzelle‘ eines Gartens entsteht, die sich weiter entwickeln und eine neue Richtung bekommen kann.</s>
+ <s>Auch der Versuch von Beginn an alle Interessensgruppen unter einen Hut zu bekommen, kann schnell ausufern und das Projekt lähmen.</s>
+ <s>Wenn beispielsweise ein interkultureller Garten entstehen soll, ist es ratsam sich deshalb zunächst auf einige wenige kulturelle Gruppen, zu denen bereits gute Kontakte bestehen, zu konzentrieren, um ein tragfähiges Fundament zu schaffen.</s>
+ </p>
+ </div>
+ <div type="subsection">
+ <head>
+ <s>Soll der Garten eine besondere Funktion erfüllen?</s>
+ </head>
+ <p>
+ <s>In GeSiGa wurden zu Beginn der Aktivierung gute Erfahrungen mit einem auf 2 Jahre temporär angelegten Garten an einem zentralen Ort in der Innenstadt gemacht.</s>
+ <s>BürgerInnen und Organisationen konnten auf einer von der Stadt zur Verfügung gestellten Fläche
+ <hi rend="bold">Abbildung 19:</hi>Bei einer Flächenbegehung reifen die Ideen aus der Planungsphase und ein erstes Gemeinschaftsgefühl entsteht (Quelle: GemeinSinnschafftGarten)
+ <pb n="25"/>ihre eigenen Hochbeete zimmern und Patenschaften übernehmen.</s>
+ <s>Dabei entstanden 16 Hochbeete mit Patenschaften von u.a. dem BUND, den Naturfreunden, der Flüchtlingshilfe, einem lokalen Bürgerverein, einem Jugendzentrum, einer Kindertagesstätte, sowie interessierten BürgerInnen aus der Nachbarschaft.</s>
+ <s>Ein derartiger Garten bringt das Gärtnern auf die Bühne der Öffentlichkeit und macht es für alle sichtbar und erfahrbar.</s>
+ <s>Wichtige Multiplikatoren erhalten mit relativ geringem Aufwand die Gelegenheit sich einzubringen.</s>
+ <s>Damit erfüllt er vor allem eine aktivierende Funktion.</s>
+ <s>Um Missverständnisse zu vermeiden sollte dies von vorneherein klar kommuniziert werden, denn nicht jedeR gärtnert gern im Schaufenster und auf begrenzte Zeit.</s>
+ </p>
+ </div>
+ <div type="subsection">
+ <head>
+ <s>Wo liegt die Trägerschaft des Gartens?</s>
+ </head>
+ <p>
+ <s>Aus der Trägerschaft des Gartens leiten sich wichtige rechtliche und organisatorische Fragen ab.</s>
+ <s>Aus der Stadt Andernach ist das Modell bekannt, dass die Stadt Obst und Gemüse auf Grünflächen anpflanzt, mit der Botschaft „Pflücken erlaubt“.</s>
+ <s>Auch ein temporärer Schaugarten, bei dem BürgerInnen und Akteure Beetpatenschaften übernehmen, kann von der Stadt getragen werden.</s>
+ <s>Für einen auf Dauer angelegten und selbstverwalteten Gemeinschaftsgarten ist eine städtische Trägerschaft hingegen eher ungeeignet.</s>
+ <s>Stattdessen können die beteiligten BürgerInnen diese selbst übernehmen und bspw. einen Verein gründen.</s>
+ <s>Wenn Unterstützerorganisationen im Boot sind, so bieten sie sich als Träger an, insbesondere wenn sie die Flächen aus eigenem Bestand zur Verfügung stellen.</s>
+ <s>Welche Rolle der Träger eines Gartens bei der Verstetigung spielen kann, wird in Schritt 5: Verstetigung ausführlicher besprochen.</s>
+ </p>
+ </div>
+ <div type="subsection">
+ <head>
+ <s>Welche rechtlichen Rahmenbedingungen gelten für die Fläche?</s>
+ </head>
+ <p>
+ <s>Vorab sollte im Dialog mit den Eigentümern, möglichen Trägern und den zuständigen Verwaltungsstellen (bspw. Stadtplanungsamt, Tiefbauamt, Feuerwehr) geklärt werden, was auf der Fläche möglich ist und was nicht.</s>
+ <s>Gibt es bauliche Richtlinien und Auflagen für das Anlegen eines Gartens und entsprechender Versorgungsinfrastrukturen, wie Wasser, Strom, Zufahrtswegen?</s>
+ <s>Welche Auflagen gelten bezüglich Abfallentsorgung, Kompostierung, Lärmschutz, Brandschutz und Sicherheit?</s>
+ <s>Wie ist die Fläche im Flächennutzungsplan ausgewiesen und liegen stadtplanerische Zukunftskonzepte für die Fläche und das Quartier vor?</s>
+ <s>Sind in der direkten Nachbarschaft größere Bauprojekte geplant?</s>
+ <s>Auch die angestrebten Nutzungsbedingungen, u.a. bezüglich Haftung, Versicherung, Pacht, Sicherheitsauflagen, geltenden Hausordnungen oder Bereitstellung von Infrastrukturen sollten vorab mit den beteiligten Akteuren geklärt werden.</s>
+ </p>
+ </div>
+ <div type="subsection">
+ <head>
+ <s>Wie ist die zeitliche Perspektive des Gartens?</s>
+ </head>
+ <p>
+ <s>Ob eine Fläche langfristig verfügbar ist, oder nur eine Zwischennutzung möglich ist, ist meist schon zu Beginn des Projektes absehbar.</s>
+ <s>Da dies weitreichende Konsequenzen für den Garten hat, sollte dies den Interessierten von Beginn an klar kommuniziert werden.</s>
+ <s>Im Idealfall ist die Nutzung dauerhaft angelegt, diese Erwartung wurde im GeSiGa-Projekt von vielen BürgerInnen geäußert.</s>
+ <s>Wenn ein Garten sich in der Nachbarschaft verwurzeln und Beete im Boden angelegt werden sollen, so braucht es eine gewisse Ruhe und Kontinuität, damit eine Gartengruppe zusammenwachsen kann.</s>
+ <s>Aber auch eine begrenzte Nutzungsdauer kann eine vielversprechende Option sein, wie der temporäre Garten in GeSiGa gezeigt hat.</s>

+ <s>AKTIVIERUNG ALS EISBERG-METAPHER</s>
+ </head>
+ <p>
+ <s>Zu Beginn des Aktivierungsprozesses kann es passieren, dass die Resonanz trotz wochenlangem Aufwand und zahllosen Gesprächen nur gering erscheint und lediglich eine Handvoll InteressentInnen den Weg zu einer Veranstaltung findet.</s>
+ <s>Diese Erfahrung wurde auch in Ge-SiGa gemacht und trotzdem war der Prozess am Ende durchaus erfolgreich.</s>
+ <s>Hilfreich ist es, den sozialen Aktivierungsprozess mit der Metapher eines Eisberges zu vergleichen.</s>
+ <s>Über der Wasseroberfläche sichtbar sind lediglich die hochengagierten Leute, die zu Veranstaltungen kommen, aktiv die Werbetrommel rühren und sich in die Gartenprojekte einbringen.</s>
+ <s>Unter der Wasseroberfläche hingegen befindet sich eine weit größere Menge an BürgerInnen, die zwar grundsätzlich Interesse haben, aber sich aktuell nicht im Prozess beteiligen.</s>
+ <s>Die Gründe dafür sind mannigfaltig: Manche haben keine Zeit, wohnen nicht in der Nähe des geplanten Gartens oder haben bereits einen Garten.</s>
+ <s>Andere sind mit den Rahmenbedingungen nicht zufrieden, können den Aufwand nicht abschätzen oder wollen grundsätzlich erst einmal abwarten was passiert.</s>
+ <s>Je länger die Aktivierung dauert, desto größer wird die Chance, dass das Potential dieser zahlreichen Passiv-Interessierten zum Leben erwacht.</s>

+ <s>EIN GEMEINSCHAFTSGARTEN ENTSTEHT GEMEINSCHAFTLICH</s>
+ </head>
+ <p>
+ <s>Wir empfehlen den Garten vom ersten Spatenstich an als gemeinschaftliches Projekt aufzuziehen.</s>
+ <s>Schnell entsteht dadurch ein Wir-Gefühl unter den MitmacherInnen und sie identifizieren sich mit dem neuen Garten.</s>
+ <s>Die Lust am Selbermachen und Mitgestalten ist eines der wichtigsten Motive fürs Gärtnern.</s>
+ <s>Gemeinschaftsgärten sind ein Ort an dem man sich ausprobieren und neue Fertigkeiten erlernen kann.</s>
+ <s>Es ist daher davon abzuraten, vorgefertigte Beete aufzustellen, die nur noch bepflanzt werden müssen.</s>
+ <s>In GeSiGa sind alle BürgerInnen zu offenen Bautagen eingeladen worden, an denen gemeinsam zu Werke gegangen wurde.</s>
+ <s>Unter der Anleitung von erfahrenen Handwerkern und Gärtnern entstanden so in kurzer Zeit zahlreiche Hochbeete und Sitzmöbel.</s>
+ <s>Da ein Garten natürlich nicht an einem einzigen Tag entsteht, ist zu empfehlen einen wöchentlichen Bautermin einzuberufen.</s>
+ <s>Das Engagement bleibt damit weiterhin gebündelt und Neulinge können einfach hinzustoßen.</s>

+ <s>Demzufolge steht Innovationskommunikation in journalistischen Angeboten, zumindest in Massenmedien, vor einem Dilemma.</s>
+ <s>Innovationstätigkeit ist für eine Volkswirtschaft als zentraler Faktor identifiziert worden.</s>
+ <s>Innovationstätigkeit ist wiederum abhängig von Irritation bestehender Lösungsansätze bzw. gewohnheiten einerseits und andererseits von der Wahrnehmung von Konkurrenz, die über eine direkte Beobachtung von bekannten Wettbewerbern hinausgeht.</s>
+ <s>Schriftenreihe der Technischen Hochschule Nürnberg Georg Simon Ohm 33 Demgegenüber steht die Tatsache, dass die Information über neue Lösungen zwangsläufig von Partialinteressen beeinflusst ist und die Tragweite bzw. der wirtschaftliche Erfolg schwer prognostizierbar ist.</s>
+ <s>Wenn der Erfolg einer Innovation zudem aber abhängig von der medialen Aufmerksamkeit ist, die Konkurrenzwahrnehmungen ermöglicht und die Akzeptanz schafft bzw. zumindest in gewissem Maße als Rationalitätsfiktion für Entscheidungen dient, dann steht Journalismus vor der Anforderung mehr über Technik, Technologien und technische Innovationen berichten zu müssen.</s>
+ <s>Die gesellschaftliche und wirtschaftliche Bedeutung von Innovationen liefert eine valide Begründung für eine ausführliche Berichterstattung.</s>
+ <s>Die Beurteilung der technischen Tragweite wird vor allem für Wirtschaftsmedien schwierig sein, dafür können andere Kriterien herangezogen werden.</s>
+ <s>Einerseits kann die Eigenschaft einer Mehrsystemauswirkung 50 wie es Nordfors formuliert hat als Basis dienen.</s>
+ <s>Ein weiteres Kriterium mit Blick auf technische Innovationen kann die Einordnung anhand der Ausprägung von (geographischen) Marktveränderungen, Technikweiterentwicklung oder der zusätzlichen Veränderung von Management- und Geschäftsmodellen bieten.</s>
+ <s>Wie in Abb. 16 skizziert, lassen sich so die Kanäle Massenmedien, Wirtschaftsmedien einerseits und Fachmedien andererseits zuordnen.</s>
+ <s>Anhand Abb. 16 ist nachzuvollziehen, welche Kommunikationsleistungen eine bestimmte Konstellation von Technikinnovation und Marktmodell impliziert.</s>
+ <s>Bei etablierten Technologien und etablierten Märkten wird sich die Kommunikation darauf beschränken, Produkte und Dienstleistungen in Erinnerung zu halten bzw. Details in Katalogform zu präsentieren.</s>
+ <s>Hier sind Rezipienten nicht auf eine Einordnung durch journalistische Angebote angewiesen.</s>
+ <s>Der Markt ist durch Preiswettbewerb und Verdrängungsmechanismen gekennzeichnet.</s>
+ <s>Treten, in diesem Kontext inkrementelle Innovationen auf, die zumeist kundeninduziert in die bestehenden Märkte eingreifen, werden vor allem fachjournalistische Leistungen gefordert sein, die diese Technologien einordnen und ggf. bewerten.</s>
+ <s>Die größte Herausforderung für Leistungsanbieter stellen Innovationen dar, die neue Märkte erschließen oder etablieren sollen.</s>
+ <s>Bei der Expansion etablierter Technologien in neue Märkte sind Fachmedien gefordert, die technische Passung oder ggf. die erforderliche Anpassung und Zertifizierungen verorten sowie Wirtschaftsmedien, die wirtschaftliche Aspekte bewerten.</s>
+ <s>Im Fall von neuen Technologien, die eine Änderung von Geschäftsmodellen nach sich ziehen, sind sowohl Massen- als auch Wirtschafts- und Fachmedien erforderlich, um im Sinne der oben beschriebenen Mechanismen einer Marktkonstitution und Stabilisierung mitwirken zu können.</s>

+ <s>Exkurs: Medienrepräsentanz von KMU und Hidden Champions </s>
+ </head>
+ <p>
+ <s>Die Gruppe der mittelständischen Unternehmen 51 oder der kleinen und mittleren Unternehmen (KMU) gilt allgemein als eine der besonderen Stärken der deutschen Volkswirtschaft.</s>
+ <s>Vor allem mit Blick auf ihre große Bedeutung für Beschäftigung und Innovation.</s>
+ <s>Betont wird zudem regelmäßig die Rolle der sogenannten Hidden Champions (Simon 1990).</s>
+ <s>(Vgl. EFI 2016: 32) Die Hidden Champions stehen wegen ihrer Größe, ihrer Ausrichtung auf Nischenmärkte bzw. auf Märkte mit einem im Vergleich geringen Nachfragevolumen, ihrer Position in der Wertschöpfungskette oder als Zulieferer für andere Unternehmen selten im Zentrum der öffentlichen Aufmerksamkeit.</s>
+ <s>Ihr Umsatz liegt klassischerweise unter einer Milliarde Euro.</s>
+ <s>Dem oben geschilderten Kriterium der Relevanz entsprechend, sind sie auch in Massenmedien als einzelne Unternehmen zwangsläufig unterrepräsentiert.</s>
+ <s>In Deutschland werden aktuell rund 1.500 Unternehmen als Hidden Champions 52 bezeichnet.</s>
+ <s>Sie beschäftigten zusammen rund 500.000 Personen und erzielen einen Jahresumsatz von rund 150 Mrd.</s>
+ <s>Euro.</s>
+ <s>Dies bedeutet, dass sie im Durchschnitt rund 320 Mitarbeiter und einen Umsatz von rund 100 Mio. Euro ausweisen.</s>
+ <s>(Vgl Rammer/Frietsch 2015: 16) Hidden Champions sind global ausgerichtet und erwirtschaften den größten Teil ihres Umsatzes auf Auslandsmärkten.</s>
+ <s>Zudem verfügen sie in ihren jeweiligen Märkten über einen so hohen Marktanteil, dass sie zu den wichtigsten Anbietern zählen und damit die Entwicklung in ihrem Markt wesentlich prägen.</s>
+ <s>Trotz umfangreicher Ratgeberliteratur, die Geschäftsmodelle, Verhalten oder Positionierung von Hidden Champions als nachahmenswert empfehlen, finden sie vor allem in der Wirtschaftsberichterstattung wenig Platz.</s>
+ </p>
+ <p>
+ <s>Gerade in der in diesem Zusammenhang beschriebenen Investitionsgüterindustrie ist die Mehrzahl der Hidden Champions, rund 85 Prozent, verortet.</s>
+ <s>Fast ein Viertel aller deutschen Hidden Champions kommen aus dem Maschinenbau.</s>
+ <s>Jeweils rund zehn Prozent sind in der Metall- und Elektroindustrie tätig.</s>
+ <s>Kleinen und mittelgroßen Unternehmen (KMU) kommen bei der Technologiegenese in unterschiedlichen Innovationssystemen unterschiedliche Rollen zu.</s>
+ <s>Legt man die Zahl der Patentanmeldungen 53 zugrunde, stammen in Norwegen, Australien, Italien und Israel etwa die Hälfte der Patentanmeldungen von KMU.</s>
+ <s>Im Durchschnitt aller Länder ist dies etwa ein Viertel und für Japan, das von wenigen Großkonzernen und ihren Konzernnetzwerken abhängig ist, sind es weniger als 10 %.</s>
+ <s>Auch Deutschland liegt in diesem internationalen Vergleich mit einer Quote von ca. 20 % am unteren Ende.</s>
+ <s>„Dies liegt zum Teil an der Branchenstruktur und dem technologischen Profil der Volkswirtschaften, zum Teil aber auch an einer Arbeitsteilung zwischen Unternehmen, die sich in der Innovationskultur ausdrückt.“ (Rammert/Frietsch 2015: 20) Beim Indikator Patentanmeldungen spielt allerdings neben der Innovationskultur auch die Industriestruktur der Länder eine bedeutende Rolle.</s>
+ <s>„Während einige Branchen stark auf Patente setzen, um ihre Erfindungen zu schützen, ist in anderen Branchen Geheimhaltung als Schutzmechanismus deutlich weiter verbreitet.“ (EFI 2016: 38) Deshalb kann die die Innovationsstärke deutscher KMU nicht ausschließlich anhand der Patentintensität beurteilt werden.</s>
+ <s>Die rund 1.500 Hidden Champions investieren mehr als fünf Prozent der gesamten FuE-Ausgaben der deutschen Wirtschaft und sind zudem für rund fünf Prozent des Neuproduktumsatzes verantwortlich.</s>
+ <s>Definiert man diesen Neuproduktumsatz enger als Weltmarktneuheiten, so tragen Hidden Champions 15 Prozent zum gesamten Umsatz mit Weltmarktneuheiten der deutschen Wirtschaft bei.</s>
+ <s>(Vgl. Rammert/Frietsch 19) Dass die Hidden Champions im globalen Wettbewerb stehen, macht eine Tatsache deutlich.</s>
+ <s>Für viele der Hidden Champions in Deutschland lässt sich ein sehr ähnliches japanisches Unternehmen finden, das in seinem Heimatmarkt Marktführer, aber auf dem Weltmarkt nur schwach vertreten ist.</s>
+ <s>Diese „sleeping dragons“ werden aktuell vom japanischen Handelsministerium im Rahmen eines Revitalisierungsprogramms für Regionen außerhalb der industriellen Ballungsräume gefördert.</s>
+ <s>(Vgl. Innovationsindiskator 2015: 52) 35 </s>
+ </p>
+ <p>
+ <s>Innovative KMU und Hidden Champions sind in der Wirtschaftspresse kaum vertreten.</s>
+ <s>Fachjournalistische Leistungsangebote stellen die Produkte und Dienstleitungen dieser Firmen sehr wohl in den Mittelpunkt und tragen so zur Marktbildung bei.</s>
+ <s>Gerade mit Blick auf die globalen Wettbewerber ist ein international orientierter Fachjournalismus erforderlich, um Wettbewerb sichtbar zu machen.</s>
+ <s>Erschwert wird dies durch die oben benannte Schutzstrategie der Geheimhaltung.</s>
+ <s>Hier ist das fachjournalistische Angebot auf die initiative Kommunikationsleistung der Leistungsanbieter angewiesen.</s>
+ <s>Die mangelnde Präsenz in Massenmedien, hier vor allem auch die fehlende Berichterstattung über Technologien, wirkt sich auch verstärkend auf ein Innovationshemmnis aus – die Fremdfinanzierung.</s>
+ <s>„Der Anteil der innovationsaktiven KMU, deren Innovationsaktivitäten durch den Mangel an internen Finanzierungsquellen behindert wurden, (liegt) (…) in der Periode 2012 bis 2014 (bei) 30 Prozent.“ (EFI 2016: 41) Für die z. B. bankenseitige Beurteilung von Innovationen bzw. für eine Weiterentwicklung eines Unternehmens einzusetzenden innovativen Technologien ist eine massenmediale Berichterstattung hilfreich.</s>
+ <s>In diesem Zusammenhang sind kreditgebende Instanzen in einer Entscheidungssituation.</s>
+ <s>Die Entscheider werden ihre Entscheidung durch Heranziehen von externen Informationen wie die der Wirtschaftsberichterstattung einordnen und absichern.</s>
+ <s>Hier kann ein journalistisches Leistungsangebot innovationsbegünstigend wirken.</s>
+ <s>Neben Möglichkeit der Beobachtung von Wettbewerbern in der Konkurrenz um die Aufmerksamkeit von Leistungsempfängern, bietet die Berichterstattung auch die gemeinsame Konkurrenz der Leistungsanbieter mit anderen branchenfremden Unternehmen, die ebenso auf Kredite des Bankensystems angewiesen sind.</s>

+ <s>6.3 Innovationsberichterstattung und Industrie 4.0 54</s>
+ </head>
+ <p>
+ <s>Auf Industrie 4.0 und die daran anschließende Berichterstattung ist bereits mehrfach verwiesen worden.</s>
+ <s>In der Tat lassen sich anhand dieses Themas einige Aspekte der Argumentation verdeutlichen.</s>
+ <s>Industrie 4.0 ist als Innovation zu bezeichnen, obwohl unter diesem Begriff weder ein Produkt noch eine einzelne Technologie zu verstehen ist.</s>
+ <s>Wie an angegebener Stelle (vgl. Fußnote 52) erläutert, ist Industrie 4.0 ein Konzept, das einen Trend zur Integration von vor allem auf Digitalisierung basierenden innovativen oder innovativ zu verknüpfenden Technologien, Dienstleistungen und Geschäftsmodellen in Produktions- und Vertriebsstrukturen beschreibt und das ausgehend von der Industrie tiefgreifende Auswirkungen auf nahezu alle Subsysteme der Gesellschaft entfaltet.</s>
+ <s>Vor diesem Hintergrund erklärt sich auch, dass dieses Thema Eingang in die Berichterstattung von Massenmedien gefunden hat.</s>
+ <s>Industrie 4.0 hat als Konzept Einfluss auf die gesamte Industrieproduktion, angefangen vom Maschinen- und Anlagenbau bis hin zu Zulieferindustrien wie der Elektroindustrie.</s>
+ <s>Zudem integriert der Ansatz Technologien aus dem IT-Sektor in die Produktionsebene.</s>
+ <s>Durch die Effekte von Flexibilisierung sowie Effizienzsteigerung hat eine Umsetzung von Industrie 4.0-Konzepten auch erhebliche Auswirkungen auf die Arbeitsplätze und die Beschäftigungssituation in einer Volkswirtschaft.</s>
+ <s>Einhergehend mit den Veränderungen am Arbeitsmarkt wird auch das Bildungssystem reagieren.</s>
+ <s>Nicht zuletzt deshalb ist auch gesamtgesellschaftlich ein Diskurs erforderlich.</s>
+ </p>
+ <p>
+ <s>Dementsprechend erfüllt Industrie 4.0 als Konzept die Bedingungen, die für eine Berichterstattung nach journalistischen Objektivitätskriterien gefordert werden.</s>
+ <s>Das Thema ist hochrelevant für die Volkswirtschaft und die gesellschaftliche Struktur in Deutschland.</s>
+ <s>Das Thema ist hinreichend abstrahiert, sodass mit der Berichterstattung keine Werbung für einen bestimmten Anbieter von Lösungen impliziert ist.</s>
+ <s>Sowohl Regierung und Opposition als auch Verbände und Gewerkschaften sind in dem aktuell zu beobachtenden Diskurs beteiligt, sodass auch hier hinreichend viele Positionen eine umfangreiche Berichterstattung rechtfertigen können.</s>
+ <s>Die im Diskurs angeführten Zahlen von Wachstumspotentialen oder auch die befürchtete umfangreiche technische Arbeitslosigkeit, rechtfertigen eine prominente Berichterstattung.</s>
+ <s>Auch für die eher auf der Organisationsebene verorteten Probleme von Innovationskommunikation bietet das Konzept bzw. in diesem Zusammenhang der Begriff Anschlussmöglichkeiten.</s>
+ <s>Der Begriff Industrie 4.0 suggeriert eine Kontinuität, die dem Argument entgegenwirkt, Rezipienten hätten Angst vor Veränderung.</s>
+ <s>Die Begrifflichkeit Industrie 4.0 oder Vierte Industrielle Revolution, hebt das Konzept von einer rein technischen Frage auf eine Ebene wirtschaftlicher Kontexte, für welche sich die Redaktionen kompetent und ausgestattet fühlen.</s>
+ <s>Durch den Transfer auf die wirtschaftliche Ebene und damit auch durch die mögliche Personalisierung auf bekannte Branchenvertreter und Politiker wird das Thema für Massenmedien vereinfacht.</s>

+ <s>7. Schlussbetrachtung und Forschungsfragen </s>
+ </head>
+ <p>
+ <s>Die Aufgabe von Medien in der Aktualisierung von Themenrelevanzen zur Akzeptanzsicherung für Technologien sowie für die Konkurrenzwahrnehmung und damit letztlich als Irritationsmechanismus und Anstoß für Innovationen oder als Plattform zur Information von Leistungsempfängern ist oben ausgeführt worden.</s>
+ <s>Gerade der Fachjournalismus in Investitionsgüterbereichen hat noch wenig Beachtung in der wissenschaftlichen Diskussion gefunden.</s>
+ <s>Hier gilt es Lücken zu schließen.</s>
+ <s>Die Bedeutung und Rolle von (Fach-)Medien im Innovationsprozess verdeutlichen Abbildung 16 als auch mit Blick auf die Produktionstechnologien Abbildung 17. Die in Abb. 16 skizzierte Verteilung von Berichterstattungsanlässen auf bestimmte Kanäle muss empirisch überprüft werden.</s>
+ <s>Ebenso die in Abb. 17 implizit getroffenen Aussagen zu Interesse von Typen journalistischer Angebote im Verlauf eines Innovationszyklus.</s>
+ <s>Dass unterschiedliche Stakeholdergruppen zu verschiedenen Zeitpunkten auf Medienleistungen angewiesen sind, lässt sich anhand der oben stehenden Ausführungen nachvollziehen.</s>
+ <s>Diese journalistischen Angebote werden zielgruppenspezifisch aufbereitet sein.</s>
+ <s>Und: in vorliegenden Untersuchungen werden nicht erhoben, welche Inhalte bzw. welchen Detailierungsgrad Entscheider von Informationen erwarten.</s>
+ <s>Hierzu bietet Industrie 4.0 einen geeigneten Forschungsanlass.</s>
+ </p>
+ <p>
+ <s>Die Frage, ob die vor allem im F&E-Prozess erforderlichen Kommunikationsangebote als journalistische Leistungen zu klassifizieren oder eher den Regeln von Fachkommunikation unter Peers zu beschreiben sind soll an dieser Stellen nicht vertieft werden.</s>
+ <s>55 Es ist allerdings anzunehmen, dass journalistische Angebote stakeholderabhängig und abhängig vom Zeitpunkt im Innovationszyklus in ihrer Wirkung variieren.</s>
+ <s>Und: die Aufmerksamkeit der benannten Medien wird anhand interner Vorgaben bzw. berufsspezifischer Einstellungen für Selektion und Transformation Unterschiede aufweisen.</s>
+ <s>Publikumsmedien werden früh Forschungsergebnisse als Bericht aus der Wissenschaft aufgreifen, da hier die entsprechenden Nachrichtenfaktoren greifen.</s>
+ <s>Die Bedenken, durch eine Berichterstattung Werbung für ein Unternehmen oder ein Produkt zu machen, greifen noch nicht, da dieses Stadium als marktfern zu beschreiben ist.</s>
+ <s>56 Das Interesse schwindet und tritt erst wieder auf, Schriftenreihe der Technischen Hochschule Nürnberg Georg Simon Ohm 37 wenn Technologien von mehreren Firmen im Markt angeboten werden.</s>
+ <s>Diese Berichterstattung hat allerdings Einfluss auf das Meinungsbild bzw. die Informationslage der Bevölkerung und auch der von einer Technologieinnovation betroffenen Belegschaft.</s>
+ <s>Fachmedien werden dann ein Thema aufgreifen, wenn Pilotphasen bzw. Feldtests anlaufen.</s>
+ <s>Hier können sie noch einen Beitrag zur Marktkonstitution leisten.</s>
+ <s>Mit Etablierung der Technik bleibt der Bedarf an journalistischen Angeboten bestehen, da sie, im Sinne der Terminologie von Abb. 16, als etablierte Technologie in einem etablierten Markt gehandelt werden.</s>
