Kulturwissenschaftliches Filmen im Umbruch: Die Filmarbeit von Edmund Ballhaus

Der Autor untersucht die Strategien und Konzepte des Göttinger Kulturwissenschaftlers Edmund Ballhaus, der mit seiner Filmarbeit die Entwicklung des wissenschaftlichen Films seit Mitte der achtziger Jahre maßgeblich beeinflußte. Detaillierte Analysen seiner ersten zwölf, in den Jahren 1986 bis 1996 entstandenen Filme verdeutlichen seine Abkehr von überholten inhaltlichen und methodischen Standards und die Entwicklung eines eigenständigen Typus des kulturwissenschaftlichen Films. Dieser rückt den Menschen in den Mittelpunkt der Betrachtung und erteilt den Gefilmten selbst das Wort. Damit wurde sowohl dem klassischen Erklärdokumentarismus des Fernsehens als auch dem distanzierten Dokumentationsstil des Instituts für den Wissenschaftlichen Film (IWF) ein neues Modell gegenübergestellt. Darüber hinaus löste sich Edmund Ballhaus von der traditionellen Arbeitsteilung in Hinblick auf Recherche, Konzeption und Umsetzung und ersetzte sie durch den selbstfilmenden Wissenschaftler, der für alle Arbeitsschritte einer Filmproduktion allein verantwortlich ist. Seine bereits 1987 veröffentlichten Forderungen verwirklichte er nicht nur in seinen Filmen, sondern auch mit der Gründung der Gesellschaft für den kulturwissenschaftlichen Film (GfkF) und der Einrichtung eines Studienganges Visuelle Anthropologie in Göttingen. In die Untersuchung einbezogen wurde eine im Anhang des Buches wiedergegebene Befragung des Filmautors, welche die Analyse um interessante Details sowohl in Hinblick auf die Entstehungsbedingungen einzelner Filme als auch auf seine persönlichen Überzeugungen und Beweggründe ergänzt.

Topologically correct intersection curves of tori and natural quadrics

This thesis provides efficient and robust algorithms for the computation of the intersection curve between a torus and a simple surface (e.g. a plane, a natural quadric or another torus), based on algebraic and numeric methods. The algebraic part includes the classification of the topological type of the intersection curve and the detection of degenerate situations like embedded conic sections and singularities. Moreover, reference points for each connected intersection curve component are determined. The required computations are realised efficiently by solving quartic polynomials at most and exactly by using exact arithmetic. The numeric part includes algorithms for the tracing of each intersection curve component, starting from the previously computed reference points. Using interval arithmetic, accidental incorrectness like jumping between branches or the skipping of parts are prevented. Furthermore, the environments of singularities are correctly treated. Our algorithms are complete in the sense that any kind of input can be handled including degenerate and singular configurations. They are verified, since the results are topologically correct and approximate the real intersection curve up to any arbitrary given error bound. The algorithms are robust, since no human intervention is required and they are efficient in the way that the treatment of algebraic equations of high degree is avoided.

Describing and explaining the foreign expansion of network managing electronic business companies (NM-EBCs)

This study deals with the internationalization behavior of a new and specific type of e-business company, namely the network managing e-business company (NM-EBC). The business model of such e-business companies is based on providing a platform and applications for users to connect and interact, on gathering and channeling the inputs provided by the users, and on organizing and managing the cross-relationships of the various participants. Examples are online communities, matching platforms, and portals. Since NM-EBCs internationalize by replicating their business model in a foreign market and by building up and managing a network of users, who provide input themselves and interact with each other, they have to convince users in foreign markets to join the network and hence to adopt their platform. We draw upon Rogers’ Diffusion of Innovations Theory and Network Theory to explain the internationalization behavior of NM-EBCs. These two theories originate from neighboring disciplines and have not yet been used to explain the internationalization of firms. We combine both theories and formulate hypotheses about which strategies NM-EBCs may choose to expand abroad. To test the applicability of our theory and to gain rich data about the internationalization behavior of these firms, we carried out multiple case studies with internationally active Germany-based NM-EBCs.

Islamische Verantwortungsethik im 17. Jahrhundert: Ein weberianisches Verständnis der Handlungsvorstellungen Katib Celebis (1609-1657)

Die vorliegende Arbeit verfolgt zwei Ziele, verbunden mit ihren Protagonisten Katib Celebi und Max Weber. Den Ausgangspunkt bildet die Frage, worin die vielfach postulierte Toleranz des Istanbuler Universalgelehrten Katib Celebi (1609-1657) begründet liegt. Zentral ist dabei das Traktat Mizanu l-haqq, mit dem Celebi vermittelnd in die damaligen Streitigkeiten zwischen Sufis und Puritanern eingriff; es werden aber auch andere Schriften elebis hinzugezogen. So werden eine mögliche Verortung Katib Celebis in einer islamischen Traditionslinie (der Illuminationsphilosophie) erörtert und zentrale Aspekte seines Bildes von Mensch, Gott und Gemeinwesen herausgearbeitet. Vor diesem Hintergrund erfolgt eine systematische Darlegung der Handlungsvorstellungen Celebis. Für das Verständnis dieser Handlungsvorstellungen wird der von Max Weber, einem Gründervater der deutschen Soziologie, geprägte Typus der Verantwortungsethik vorgeschlagen. Die Handhabbarmachung des von Weber geprägten Typus für den Kontext Katib Celebis bedarf der ausführlichen Diskussion und Begründung. Ein dahingehender Theorietest bildet deshalb den zweiten Strang dieser Arbeit. Die erfolgte Universalisierung der Weberschen Typologie erlaubt ihre zukünftige Anwendung auch auf andere Forschungskontexte.

Diel and seasonal variation in the use of a nearshore sandflat by a ray community in a near pristine system

Knowledge of movements and habitat use is necessary to assess a species’ ecological role and is especially important for mesopredators because they provide the link between upper and lower trophic levels. Using acoustic telemetry, we examined coarse-scale diel and seasonal movements of elasmobranch mesopredators on a shallow sandflat in Shark Bay, Western Australia. Giant shovelnose rays (Glaucostegus typus) and reticulate whiprays (Himantura uarnak) were most often detected in nearshore microhabitats and were regularly detected throughout the day and year, although reticulate whiprays tended to frequent the monitored array over longer periods. Pink whiprays (H. fai) and cowtail stingrays (Pastinachus atrus) were also detected throughout the day, but were far less frequently detected. Overall, there was no apparent spatial or temporal partitioning of the sandflats, but residency to the area varied between species. In addition, ray presence throughout the year suggests that previously observed differences in seasonal abundance are likely because of seasonal changes in habitat use rather than large-scale migrations. Continuous use of the sandflats and limited movements within this ray community suggests that rays have the potential to be a structuring force on this system and that focusing on nearshore habitats is important for managing subtropical ray populations.

Microhabitat Selection by Marine Mesoconsumers in a Thermally Heterogeneous Habitat: Behavioral Thermoregulation or Avoiding Predation Risk?

Habitat selection decisions by consumers has the potential to shape ecosystems. Understanding the factors that influence habitat selection is therefore critical to understanding ecosystem function. This is especially true of mesoconsumers because they provide the link between upper and lower tropic levels. We examined the factors influencing microhabitat selection of marine mesoconsumers – juvenile giant shovelnose rays (Glaucostegus typus), reticulate whiprays (Himantura uarnak), and pink whiprays (H. fai) – in a coastal ecosystem with intact predator and prey populations and marked spatial and temporal thermal heterogeneity. Using a combination of belt transects and data on water temperature, tidal height, prey abundance, predator abundance and ray behavior, we found that giant shovelnose rays and reticulate whiprays were most often found resting in nearshore microhabitats, especially at low tidal heights during the warm season. Microhabitat selection did not match predictions derived from distributions of prey. Although at a course scale, ray distributions appeared to match predictions of behavioral thermoregulation theory, fine-scale examination revealed a mismatch. The selection of the shallow nearshore microhabitat at low tidal heights during periods of high predator abundance (warm season) suggests that this microhabitat may serve as a refuge, although it may come with metabolic costs due to higher temperatures. The results of this study highlight the importance of predators in the habitat selection decisions of mesoconsumers and that within thermal gradients, factors, such as predation risk, must be considered in addition to behavioral thermoregulation to explain habitat selection decisions. Furthermore, increasing water temperatures predicted by climate change may result in complex trade-offs that might have important implications for ecosystem dynamics.
