My dissertation is concerned with contemporary (Anglo-)Canadian immigrant fiction and proposes an analytic grid with which it may be appreciated and compared more adequately. As a starting-point serves the general observation that the works of many Canadian immigrant writers are characterised by a focus on their respective home cultures as well as on their Canadian host culture. Following the ground-breaking work of Northrop Frye, Margaret Atwood and David Staines, the categories of "there" and "here" are suggested in order to reflect this double encoding of Canadian immigrant literature. However, "here" and "there" are more than spatial configurations in that they represent a concern with issues of multiculturalism and postcolonialism. Both of which are informed by an emphasis on difference and identity, and difference and identity are also what the narratives of M.G. Vassanji, Neil Bissoondath and Rohinton Mistry are preoccupied with. My study sets out to show two things: On the one hand, it attempts to exemplify the complexity and interrelatedness of "there" and "here" in a representative fashion. Hence in their treatments of difference, M.G. Vassanji, Neil Bissoondath and Rohinton Mistry come up with comparable identity constructions "here" and "there" respectively. On the other hand, special attention is paid to the strategies by which Vassanji, Bissoondath and Mistry construct difference and corroborate their respective understandings of identity.

One of the current issues in psycholinguistics is how the frequency of syntactic structures influences the mental processing of sentences, especially in the case of ambiguous constructions. The present work attempts to shed light on this issue from the perspective of computational and corpus linguistics. Existing theories of human sentence processing assign different roles to frequency, varying from certain 'principle-based' models that completely ignore it to 'experience-based' models relying on frequency alone. The present work develops a frequency-based parsing component that may be combined with other factors influencing disambiguation. This module, named the Optimized Frequency Constraint (OFC), addresses questions largely left open by existing frequency-based models: How are the frequencies of syntactic structures stored mentally? When does the human sentence processing mechanism access this stored information, and in what sequence? OFC is then applied to a range of syntactic constructions in German (licensing, attachment of phrases and relative clauses, word order, etc.) that have been used in psycholinguistic experiments. The settings of OFC's parameters are determined by analyzing German corpus data. The predictions based on OFC are confirmed by the results reported in the psycholinguistic literature in most cases, indicating that OFC offers psychologically valid predictions of the influence of frequency in human parsing.

This dissertation investigates the psychological and endocrinological make-up of patients with functional gastrointestinal disorders (FGD). Patients with irritable bowel syndrome and/or non ulcer dyspepsia were compared with healthy control subjects on several parameters: psychological disorders, bodily complaints, depressed mood, anxiety, chronic stress, personality and basal activity, reactivity (hCRH-test) as well as feedback-sensitivity(Dexamethasone-suppression-test) of the hypothalamic-pituitary-adrenocortical (HPA) system. Patients with FGD had different -mostly higher- scores in almost every psychological/psychometric measure. Furthermore, results of the endocrinological studies indicate a down-regulated HPA activity in patients with FGD.

Habitat selection of nine songbird species (Sylviidae, Prunellidae, Emberizidae, Fringillidae, Laniidae) in a semi-open transitional landscape (wood/meadow ecotone) is assessed and compared by a quantitative approach over a period of three years. The structural diversity and heterogeneity of this landscape allows a common occurrence to bird species that are spatially segregated in other habitats. On the one hand habitat selection, which in this study is defined by the choice of vegetation structures at the microhabitat level, is regarded as the confrontation of the single bird individuals with their environment and on the other hand as a common trait of subpopulations. The process of habitat selection is only real at the level of the individual. Drawing against this background, a model for the quantification of habitat selection is introduced, making possible an objective analysis of both individual and average habitat selection (not explaining the process itself, however, that leads to the observed habitat selection). The influence of several structural features, mainly regarding the shape of vegetational subunits, on the dispersion of the birds on the plots is analyzed by means of quantitative methods (factor analysis, cluster analysis, discriminant analysis). Preferences and avoidances, constancy in time and space and the degree of selectivity of the specific choice of vegetational structures are discussed in detail for each bird species. There is quantitative evidence that along with increasing abstraction from the individual in the form of spatially increasing data aggregation, the specific distinctness of habitat preferences as a common trait increases. This happens, however, at the expense of information about the variability of the individual selective behaviour. Therefore the flexibility of a bird species would be underrated cosiderably, confining habitat selection to its meaning as an integrating trait of populations. Habitat selection is a dynamic process. It is shown that the structural offer in a landscape strongly influences the result of the species" habitat selection. The availability of vegetational structures on a plot determines the quantitative structural framework, which may be more or less quantitatively modified by the single species. Nevertheless, the structural offer is reflected clearly in the selected structural portions of the bird species. Therefore opportunism and selectivity in the form of structural preferences and avoidances in habitat selection have to be interpreted against the background of the quantitative composition of the vegetational structures that a landscape offers to the birds.

Hamanns knight tombs - Reception and transformation of a French type The thesis deals with an important group of tombs in the history of medieval art. The object of research is a particular group of figurative tombs for nobles from Marburg, Cappenberg, Bielefeld and Münstereifel. These tombs were brought to art historians attention by Richard Hamann in the year 1929. For the first time the research at hand considers the tombs as particularly instructive examples thus strengthening the basis for medieval studies. They also explain the function of memorial sculpture in medieval history. Interdisciplinary approaches of medieval studies are combined with critical valuation of historical research as well as fundamental research and the interpretation of sources. The up-to-date unpublished sources from the starting point for the specific research of the tombs. Biographic-genealogical aspects, actual church law, the historical-social context and the memorial purpose are the research areas from which the meaning of tombs was elaborated, as well as taking into consideration the medieval mentality about death and memory. The results of the research give a new valuation of these tombs, which form a key position regarding the spectrum of their statement for the development of art history and memorial history in the 14th century. The tombs reveal contact between artist and patron. They help to find out more about social circumstances intertwined with medieval art comissions. These memorials prove the existence of artistic grave specialists in the western German region of the 14th century, who were recommendet in turn by the closely related noble familiy. On a social-cultural level these memorials show the importance of royal French art as a distinctive model further more expressing the need for oneself to express social status by the means of art. These memorials are closely related to certain people. They are crucial to the research of medieval memorial sculpture. The memorial from Cappenberg is a paradigm for the shift from a cult ideology to a pure economic ideology thus showing proof of patroned memorials. Whereas the tombs in Marburg, Bielefeld and Münstereifel are keyworks showing the relevance of spontaneous and private memorial of the dead.
