Diese Dissertation handelt von Grenz- und Fremdheitskonstruktionen in iranischen Reiseberichten (sowohl Europa- als auch Russlandreiseberichte) des 19. Jahrhunderts. Durch die Untersuchung der zentralen sozialen und kulturellen Strukturen und Prozesse der Grenz- und Fremdheitserzeugung ist in dieser Studie, die iranische Gesellschaft, in den Besonderheiten ihrer eigenen Geschichte, durch ihre äußeren Begegnungen und Interdependenzen geforscht worden. Anhand der theoretischen Fokussierung auf zwei Konzepte, nämlich Fremdheit und kulturelle und soziale Grenze, wurde die Entwicklung der iranischen Gesellschaft in Anbetracht ihrer Beziehung zu den europäischen Ländern im Laufe des 19. Jahrhunderts rekonstruiert. Zwar ist die Arbeit primär eine soziologische Studie, konnte aber den historischen Kontext der Ereignisse und die literarische Beschaffenheit der Reisetexte nicht unbeachtet lassen. / This work is a comprehensive sociological study on travelogues, specifically with focus on the Iran’s 19th century history (Qajar Dynasty). It presents an analysis that sociologically and systematically registers the staging of cultural boundaries and the socio-historical construction of foreignness in the Iranian society, on the basis of selected Persian travel literature. This study has tried to show that cultural and social boundaries are relational and historical constructs which, in case of Iran, are dramatically affected by the encounters of Iranians (statesmen, students, tourists, etc.) with western countries (Western Europe and Russia).

Die Problematik der Darstellung eines Serienmörders in der Fiktion, liegt darin, daß es bereits bei der Konstruktion eines realen Serienmörders insofern Schwierigkeiten gibt, als daß er selbst sich als jemand der Realität übergeordnet betrachtet. Damit gestaltet sich die Porträtierung des fiktiven Gegenstückes anders herum und reflektiert die Identität des wahren Mörders. Dieses wird aufgezeigt anhand der fiktiven Figuren Hans Beckert aus Fritz Langs M – Eine Stadt sucht einen Mörder (1931), Jean-Baptiste Grenouille aus Patrick Süskinds Das Parfüm (1985) und Peter und Paul aus Michael Hanekes Film Funny Games (1997). Jeder dieser vier Mörder zeichnet sich dadurch aus willens zu sein sowohl körperliche als auch realitätseinschränkende Grenzen zu überschreiten. Das Morden steht dabei im Zentrum, dem wiederum eine Selbstkonstruktion zu Grunde liegt. Untermalt wird dies durch der Fiktion allein möglichen Ausstattung der Täter mit besonderen Fähigkeiten der Imagination die Realität zu entziehen.

Die Tätigkeiten im Notarzt- und Rettungsdienst sind häufig mit persönlichen Gefährdungen verbunden. Im Raum steht aber auch immer die Problematik von Gefährdungssituationen, die durch den Notarzt "nur" als solche wahrgenommen, sozusagen "empfunden" werden. In dieser Arbeit wird v. a. vor dem Hintergrund der Erforderlichkeit und Zumutbarkeit die Frage prinzipiell diskutiert, ob und inwieweit ein Notarzt zum Handeln verpflichtet ist. Im Ergebnis ist objektiv-typisierend auf den Facharztstandard bzw. den Indikationskatalog für den Notarzteinsatz in Kombination mit arzt-/berufsrechtlichen Gesichtspunkten im engeren Sinne (z. B. Freiberuflichkeit) abzustellen. Es wird sich jedenfalls immer um eine Einzelfallbetrachtung und um eine individuelle, fallbezogene Entscheidung handeln. Bei seltenen, sehr unwahrscheinlichen Situationen mit relativer Ermangelung von objektiv-typisierbaren Gesichtspunkten werden die Anforderungen, aber auch die Chancen, an die "höchstpersönliche" Berufsausübung, an die Persönlichkeit des Arztes (v. a. in der Entscheidungsfindung) umso größer werden.

Esta tese tem como objetivo investigar o conceito de comunidade ética, temática por Kant desenvolvida na terceira parte do escrito A religião nos limites da simples razão. Tal investigação se direciona no sentido de abordar o que denominamos de desdobramento do conceito de comunidade ética. Kant, cabe dizer, não se serve ou aponta explicitamente para algo semelhante a um desdobramento conceitual da noção de comunidade ética. Com efeito, a sua argumentação permite que tal avaliação seja extraída, uma vez que há, relativamente à noção de comunidade ética, uma visível sobreposição de definições. A comunidade ética, inicialmente, é definida nos termos de uma união dos homens sob leis de virtude. Essa definição basilar se impõe em vista do que Kant denomina de estado de natureza ético, um estado de corrupção moral que se apresenta sob a alçada da coletividade. Ocorre que, embora esse conceito de comunidade ética (enquanto uma união sob leis de virtude) supra a necessidade inicial de se pensar uma condição antagônica ao estado de natureza ético, ele por si só, na medida em que Kant pretende lhe conferir maior inteligibilidade, não se sustenta. Em vista das necessidades argumentativas que se impuseram, seja de clareza, seja de completude, Kant foi levado a desdobrar a noção inicial de uma união sob leis de virtude em mais outros dois domínios. Daí que a comunidade ética também foi definida nos termos de um povo de Deus sob leis de virtude e, por último, nos termos de uma igreja. O desdobramento do conceito de comunidade ética, cabe ainda dizer, não diz respeito a uma negação do que anteriormente havia sido definido, mas a uma agregação de informações ou momentos argumentativos apresentados no sentido de melhor traduzir o que Kant pretende explicitar quando se vale dessa noção. A tese tem, enfim, por um lado, o objetivo de reconstruir o desdobramento do conceito de comunidade ética e, por outro, identificar as necessidades argumentativas que levaram Kant a acrescentar mais dois estágios de compreensão para tal conceito. / This thesis aims at investigating the concept of ethical community, topic developed by Kant in the third part of the work Religion within the boundaries of mere reason. Such an investigation is directed towards approaching what we call the unfolding of the concept of ethical community. Kant, it must be said, does not use or point explicitly to something like a conceptual unfolding of the notion of ethical community. Indeed, his argumentation allows such an assessment to be drawn, since there is, related to the notion of ethical community, a visible overlap of definitions. Initially, ethical community is defined in terms of a union of men under laws of virtue. This basic definition is imposed in view of what Kant names as the ethical state of nature, a state of moral corruption which is presented under the jurisdiction of collectivity. Although this concept of ethical community (as a union under the laws of virtue) supplies the initial need of thinking about an antagonistic condition to the ethical state of nature, the concept, alone, does not sustain itself when Kant intends to give it more intelligibility. In view of the argumentative needs that are imposed, concerning clarity or completeness, Kant was led to deploy the initial notion of a union under the laws of virtue into two other domains. Thus, ethical community was also defined in terms of a people of God under the laws of virtue and, at last, in terms of a church. The unfolding of the concept of ethical community is not concerned with a negation of what had previously been defined, but with an aggregation of information or argumentative moments presented to better translate what Kant intended to make explicit when employing this notion. To sum up, the thesis, on the one hand, has the objective of reconstructing the unfolding of the concept of ethical community and, on the other hand, of identifying the argumentative needs which led Kant to add more stages of comprehension to this concept.

The 21st century has seen a reinvention of how modern electronics impact our daily lives; silicon-electronics and organic electronics are currently at the core of modern electronics. Recent advances have demonstrated that conductive metal–organic frameworks (MOFs), as another unique class of electronic materials, are emerging to provide additional possibility for multifunctional electronic devices that brings us “MOFtronics”. Typically, two-dimensional conjugated MOFs (2D c-MOFs) are a novel class of layer-stacked MOFs with in-plane extended π-conjugation that exhibit unique properties such as intrinsic porosity, crystallinity, stability, and electrical conductivity as well as tailorable band gaps. Benefiting from their unique features and high conductivity, 2D c-MOFs have displayed great potential for multiple high-performance (opto)electronic, magnetic, and energy devices. In this review article, we introduce the chemical and synthetic methodologies of 2D c-MOFs, intrinsic influences on their electronic structures and charge transport properties, as well as multifunctional applications of this class of materials for MOFtronics and potential power sources for MOFtronics. We highlight the benefits and limitations of thus-far developed 2D c-MOFs from synthesis to function and offer our perspectives in regard to the challenges to be addressed.

Biomasseplantagen und Aufforstung zur terrestrischen Kohlenstoffdioxid-Entfernung werden derzeit als Möglichkeit diskutiert um dem anthropogenen Treibhauseffekt entgegenzuwirken. Für die Bewertung solcher Maßnahmen ist ein umfassendes Verständnis ihrer Nachhaltigkeit und möglichen Konsequenzen erforderlich. In dieser Arbeit werden biogeochemische und hydrologische Auswirkungen von Biomasseplantagen und Aufforstung quantitativ und im Kontext der Planetarischen Grenzen (PG) analysiert. Simulationen mit einem globalen Vegetationsmodell zeigen, dass die Auswirkungen von Biomasseplantagen auf die Biosphäre nicht zu vernachlässigen sind und die der historischen landwirtschaftlichen Bodennutzung noch überschreiten können. Außerdem werden Szenarien zur räumlichen Verteilung von Biomasseplantagen unter Berücksichtigung von regionalen und globalen PG für biogeochemische Flüsse, Intaktheit der Biosphäre, Landnutzungswandel und Süßwassernutzung evaluiert. Unter Einhaltung regionaler PG können nur marginale Potentiale erzielt werden. Unter kompletter Ausnutzung des Risikobereichs könnten 1.4-6.9 GtC/a entzogen werden, abhängig von Biomasseverwertungs- und Kohlenstoffspeicherungseffizienzen. Die Relevanz von koevolutionärer Dynamik zwischen dem Kohlenstoffkreislauf und gesellschaftlichem Eingreifen wird mit einem konzeptionellen Modellierungsansatz im Kontext der PG aufgezeigt. Eine Fokussierung auf das Klimaproblem ohne die ganzheitliche Berücksichtigung von erdsystemischen Interaktionen kann ungewollte Überschreitung anderer PG zur Folge haben. Die Kombination von Bevölkerungswachstum und Nahrungsmittelbedarf mit der Minimierung von Kohlenstoff- und Biodiversitätsverlusten zeigt Möglichkeiten und Grenzen für terrestrische Kohlenstoffspeicherung auf. Räumliche Umverteilung in hochproduktive Regionen sowie substantielle landwirtschaftliche Produktivitätssteigerungen ermöglichen die Ernährung von 9 Milliarden Menschen sowie ein Kohlenstoffspeicherungspotential von bis zu 98 GtC. / Terrestrial carbon dioxide removal (tCDR) via afforestation or biomass plantations are discussed as options to counteract anthropogenic global warming. Therefore, it is important to understand sustainability limits and implications of tCDR in the context of Earth system dynamics. This thesis provides a model based assessment of biogeochemical and hydrological side-effects of biomass plantations and afforestation in the context of planetary boundaries (PBs), delimiting a safe operating space for humanity. Simulations with a global vegetation model indicate considerable biogeochemical and hydrological consequences of biomass plantations which are even larger than those of historical agricultural land use. Further, land use scenarios of biomass plantations are developed with a multi-objective optimisation model considering the PBs for biogeochemical flows, biosphere integrity, land system change and freshwater use. Respecting PBs yields almost zero tCDR potential. The transgression of PBs into a zone of increasing risk of feedbacks at the planetary scale can provide considerable tCDR potentials of 1.4-6.9 GtC/a, depending on efficiency of biomass conversion and carbon capture and storage. The importance of co-evolutionary dynamics of the Earth''s carbon cycle and societal interventions through tCDR is demonstrated with a conceptual modelling approach in the context of carbon-related PBs. A focus on climate change without an integrated trade-off assessment may lead to navigating the Earth system out of the safe operating space due to collateral transgression of other PBs. Integrating population growth and food demand while minimising carbon and biodiversity loss demonstrates opportunities and limitations for tCDR. Substantial improvements of crop and livestock productivities and the displacement of agricultural production into regions of high productivity yield sustainable terrestrial carbon sequestration potentials of up to 98 GtC while feeding 9 billion people.

Ein großes Hindernis für die Anwendbarkeit von oxidischen Perowskiten in elektrotechnischen oder spintronischen Applikationen, ist die Größe der spezifischen Temperaturen, bei der die physikalischen Phänomene, wie Ferromagnetismus oder Hochtemperatur-Supraleitung, beobachtet werden können. Die physikalischen Eigenschaften der Perowskite zeigen eine Abhängigkeit von der Ordnung der verschiedenartigen Metallionen in mehrkomponentigen Systemen. Die Abhängigkeit ergibt sich durch den Einfluss der Metallionen auf die Elektronenkonfiguration und elastischen Verspannung innerhalb des Materials. Man spricht in diesem Zusammenhang auch von der Kontrolle der Füllung und der Bandbreite der elektronischen Bänder im Material durch die Wahl der Metallionen. Die Zielsetzung dieser Arbeit ist die Präparation und Charakterisierung von künstlich A-Platz geordneten schmal- und breitbandigen Manganat Dünnfilmen als auch von natürlich B-Platz geordneten ferro-/ferrimagnetischen doppelperowskitischen Dünnfilmen. Für die Präparation der dünnen Schichten wurde die unkonventionelle Metallorganischen Aerosol Deposition (MAD) verwendet. Es konnte gezeigt werden, dass diverse künstlich oder natürlich Kationengeordnete Perowskite mit der MAD Technologie präpariert werden können. Die lagenweise A-Platz Ordnung in Manganaten führt, über die Modulation der Gitterverspannung und der Elektronenbesetzung im eg-Band der Manganionen, zu modifizierten elektronischen und magnetischen Eigenschaften. In schmalbandigen CMR Manganaten wurde die PS und somit der CMR über die Ordnung beeinflusst, während in breitbandigen CMR Manganaten ein Weg aufgezeigt werden konnte, der zu Übergangstemperaturen TC > 370K führen kann. In geordneten, ferromagnetischen Doppelperowskiten wurde der Einfluss und die Anwesenheit von Antiphasen-Grenzen dargelegt. Über die Einführung einer aktiven Valenz-Kontrolle, konnte die Präparation von halbmetallischen, ferrimagnetischen Doppelperowskiten mit der MAD Technologie ermöglicht werden.
