This MA thesis examines novels by Native American authors of the 20th century in regard to their representation of conflicts between the indigenous population of North America and the dominant Christian religion of the mainstream society. Several major points can be followed throughout the century, which have been presented repeatedly and discussed in various perspectives. Historical conflicts of colonization and Christianization, as well as the perpetual question of Native American Christians -- 'How can you go to a church that killed so many Indians?' [Alexie, Reservation Blues] -- are debated in these novels and analyzed in this paper. Furthermore, I have tried to position and classify the works according to their representation of these problems within literary history. Following Charles Larson's chronologic and thematic examination of American Indian Fiction, the categories rejection, (syncretic) adaptation, and postmodern-ironic revision are introduced to describe the various forms of representation. On the basis of five main examples, we can observe an evolution of contemporary Native American literature, which has liberated itself from the narrow definition of the 1960s and 1970s, in favor of a broader and more varied approach. In so doing, and by means of intercultural and intertextual referencing, postmodern irony, and a new Indian self-confidence, it has also taken a new position towards the religion of the former colonizer.
This paper focuses on mysteries written by the Afro-American women authors Barbara Neely and Valerie Wilson Wesley. Both authors place a black woman in the role of the detective - an innovative feature not only in the realm of female detective literature of the past two decades but also with regard to the current discourse about race and class in US-American society. This discourse is important because detective novels are considered popular literature and thus a mass product designed to favor commercial instead of literary claims. Thus, the focus is placed on the development of the two protagonists, on their lives as detectives and as black women, in order to find out whether or not and how the genre influences the depiction of Afro-American experiences. It appears that both of these detective series represent Afro-American culture in different ways, which confirms a heterogenic development of this ethnic group. However, the protagonist's search for identity and their relationships to white people could be identified as a major unifying claim of Afro-American literature. With differing intensity, the authors Neely and Wesley provide the white or mainstream reader with insight into their culture and confront the reader's ignorance of black culture. In light of this, it is a great achievement that Neely and Wesley have reached not only a black audience but also a growing number of white readers.
To characterise the habitat preferences of ring ouzel (Turdus torquatus) and blackbird (T. merula) in Switzerland, we adopt species distribution modelling and predict the species’ spatial distribution. We model on two different scales to analyse in how far downscaling leads to a different set of predictors to describe the realised habitat best. While the models on macroscale (grid of one square kilometre) cover the entire country, we select a set of smaller plots for modelling on territory scale. Whereas ring ouzels occur in altitudes above 1’000 m a.s.l. only, blackbirds occur from the lowlands up to the timber line. The altitudinal range overlap of the two species is up to 400 m. Despite both species coexist on macroscale, a direct niche overlap on territory scale is rare. Small-scale differences in vegetation cover and structure seem to play a dominant role for habitat selection. On macroscale however, we observe a high dependency on climatic variables mainly representing the altitudinal range and the related forest structure preferred by the two species. Applying the models for climate change scenarios, we predict a decline of suitable habitat for the ring ouzel with a simultaneous median altitudinal shift of +440 m until 2070. In contrast, the blackbird is predicted to benefit from higher temperatures and expand its range to higher elevations.
This diploma thesis deals with the process of political and administrative decentralisation in the Kingdom of Lesotho. Although decentralization in itself does not automatically lead to development it became an integral part of reform processes in many developing countries. Governments and international donors consider efficient decentralized political and administrative structures as essential elements of “good governance” and a prerequisite for structural poverty alleviation. This paper seeks to analyse how the given decentralization strategy and its implementation is affecting different features of good governance in the case of Lesotho. The results of the analysis confirm that the decentralisation process significantly improved political participation of the local population. However, the second objective of enhancing efficiency through decentralisation was not achieved. To the contrary, in the institutional design of the newly created local authorities and in the civil service recruitment policy efficiency considerations did not matter. Additionally, the created mechanisms for political participation generate relevant costs. Thus it is impossible to judge unambiguously on the contribution of decentralisation to the achievement of good governance. Different subtargets of good governance are influenced contrarily. Consequently, the adequacy of the concept of good governance as a guiding concept for decentralisation policies can be questioned. The assessment of the success of decentralisation policies requires a normative framework that takes into account the relations between both participation and efficiency. Despite the partly reduced administrative efficiency the author’s overall impression of the decentralisation process in Lesotho is positive. The establishment of democratically legitimised and participatory local governments justifies certain additional expenditure. However, mistakes in the design and the implementation of the decentralisation strategy would have been avoidable.
Three quantum cryptographic protocols of multiuser quantum networks with embedded authentication, allowing quantum key distribution or quantum direct communication, are discussed in this work. The security of the protocols against different types of attacks is analysed with a focus on various impersonation attacks and the man-in-the-middle attack. On the basis of the security analyses several improvements are suggested and implemented in order to adjust the investigated vulnerabilities. Furthermore, the impact of the eavesdropping test procedure on impersonation attacks is outlined. The framework of a general eavesdropping test is proposed to provide additional protection against security risks in impersonation attacks.
Today about 24 Million people worldwide suffer from dementia, Alzheimer’s Disease accounts for approximately 50-60% of all dementia cases. As the prevalence of dementia grows with increasing age Alzheimer’s Disease becomes more and more of an issue for society as the proportion of elderly people increases from year to year. It is well established, that the amino acid glutamate - quantitatively being the most important neurotransmitter in the central nervous system (CNS) - may reach toxic concentrations if not cleared from the synaptic cleft into which it is released during transmittance of action potentials. In Alzheimer’s Disease there is strong evidence for a generally impaired glutamate uptake system which in turn is thought to result in toxic levels of the amino acid with the potential to kill off neurons. The excitatory amino acid transporter 1 (EAAT1) belongs to the family of Na+-dependent glutamate transporter and accounts together with EAAT2 for most of the glutamate uptake in the CNS. In this project a new splice variant of EAAT1, skipping exon 3 was detected in human brain samples and subsequently called EAAT1Δ3, this being the second splice variant found after the recent detection of EAAT1Δ9. A method was developed to quantify the transcript of EAAT1 wt, EAAT1Δ3 and EAAT1Δ9 by means of real-time PCR. Samples were taken from different brain areas of a set of control and AD cases. The areas chosen for examination are affected differently in Alzheimer’s Disease, this was used an internal control for the experiments done in this project as to determine whether any effect observed is specific for AD, i.e. AD affected areas or is generally seen in all areas examined. The results of this project show that EAAT1Δ3 is transcribed in very low copy numbers making up a proportion of 0.15% of EAAT1 wt whereas EAAT1Δ9 is transcribed in a considerably large proportion of EAAT1 wt of 26.6%. It was moreover found that all EAAT1 variants are transcribed at significantly lower rates (P<0.0001) in AD cases, supporting the theory that EAAT1 protein expression is reduced to a point where glutamate uptake normally mediated by this transporter is impaired. This in turn is thought to result in toxic levels glutamate accounting for neuronal loss in the disease. No area-dependent effects were found, suggesting that the reduction of EAAT1 transcription is rather a result of an underlying general mechanism present in AD. Further research will have to be done to assess the degree of EAAT1 expression in AD and whether those future findings match with the result of this project.
Writing an alternative Australia : women and national discourse in nineteenth-century literature
(2007)
In this thesis, I want to outline the emergence of the Australian national identity in colonial Australia. National identity is not a politically determined construct but culturally produced through discourse on literary works by female and male writers. The emergence of the dominant bushman myth exhibited enormous strength and influence on subsequent generations and infused the notion of “Australianness” with exclusively male characteristics. It provided a unique geographical space, the bush, on and against which the colonial subject could model his identity. Its dominance rendered non-male and non-bush experiences of Australia as “un-Australian.” I will present a variety of contemporary voices – postcolonial, Aboriginal, feminist, cultural critics – which see the Australian identity as a prominent topic, not only in the academia but also in everyday culture and politics. Although positioned in different disciplines and influenced by varying histories, these voices share a similar view on Australian society: Australia is a plural society, it is home to millions of different people – women, men, and children, Aboriginal Australians and immigrants, newly arrived and descendents of the first settlers – with millions of different identities which make up one nation. One version of national identity does not account for the multitude of experiences; one version, if applied strictly, renders some voices unheard and oppressed. After exemplifying how the literature of the 1890s and its subsequent criticism constructed the itinerant worker as “the” Australian, literary productions by women will be singled out to counteract the dominant version by presenting different opinions on the state of colonial Australia. The writers Louisa Lawson, Barbara Baynton, and Tasma are discussed with regard to their assessment of their mother country. These women did not only present a different picture, they were also gifted writers and lived the ideal of the “New Women:” they obtained divorces, remarried, were politically active, worked for their living and led independent lives. They paved the way for many Australian women to come. In their literary works they allowed for a dual approach to the bush and the Australian nation. Louisa Lawson credited the bushwoman with heroic traits and described the bush as both cruel and full of opportunities not known to women in England. She understood women’s position in Australian society as oppressed and tried to change politics and culture through the writings in her feminist magazine the Dawn and her courageous campaign for women suffrage. Barbara Baynton painted a gloomy picture of the Australian bush and its inhabitants and offered one of the fiercest critiques of bush society. Although the woman is presented as the able and resourceful bushperson, she does not manage to survive in an environment which functions on male rules and only values the economic potential of the individual. Finally, Tasma does not present as outright a critique as Barbara Baynton, however, she also attests the colonies a fascination with wealth which she renders questionable. She offers an informed judgement on colonial developments in the urban surrounds of the city of Melbourne through the comparison of colonial society with the mother country England. Tasma attests that the colonies had a fascination with wealth which she renders questionable. She offers an informed judgement on colonial developments in the urban surrounds of the city of Melbourne through the comparison of colonial society with the mother country England and demonstrates how uncertainties and irritations emerged in the course of Australia’s nation formation. These three women, as writers, commentators, and political activists, faced exclusion from the dominant literary discourses. Their assessment of colonial society remained unheard for a long time. Now, after much academic excavation, these voices speak to us from the past and remind us that people are diverse, thus nation is diverse. Dominant power structures, the institutions and individuals who decide who can contribute to the discourse on nation, have to be questioned and reassessed, for they mute voices which contribute to a wider, to the “full”, and maybe “real” picture of society.
This thesis addresses real-time rendering techniques for 3D information lenses based on the focus & context metaphor. It analyzes, conceives, implements, and reviews its applicability to objects and structures of virtual 3D city models. In contrast to digital terrain models, the application of focus & context visualization to virtual 3D city models is barely researched. However, the purposeful visualization of contextual data of is extreme importance for the interactive exploration and analysis of this field. Programmable hardware enables the implementation of new lens techniques, that allow the augmentation of the perceptive and cognitive quality of the visualization compared to classical perspective projections. A set of 3D information lenses is integrated into a 3D scene-graph system: • Occlusion lenses modify the appearance of virtual 3D city model objects to resolve their occlusion and consequently facilitate the navigation. • Best-view lenses display city model objects in a priority-based manner and mediate their meta information. Thus, they support exploration and navigation of virtual 3D city models. • Color and deformation lenses modify the appearance and geometry of 3D city models to facilitate their perception. The presented techniques for 3D information lenses and their application to virtual 3D city models clarify their potential for interactive visualization and form a base for further development.
The intention of this master-thesis is a critical assessment of the European Union´s (EU) approach to external democracy promotion in Morocco. The study follows a comparative approach and compares the approach pursued by the EU within the framework of the European Neighbourhood Policy (ENP), incepted in 2004, with the approach that it had developed up until then under the framework of the Euro-Mediterranean Partnership (EMP). The comparison is done with the intention to analyse, to what degree it is justified to speak of a new impetus for democratisation through the ENP in partner countries. The analysis takes into consideration the range of possible instruments for external democracy promotion in the categories „diplomacy“, „conditionality“ and „positive instruments“. For the comparison of democracy promotion under the EMP and the ENP it is suggested to compare the implemented measures in respect to three distinct dimensions: As a first dimension, instruments of democracy promotion are analysed with respect to the focus on indirect vs. direct instruments, e.g. those which aim at establishing socio-economic preconditions favourable to successful democratisation, vs. those which immediately intervene in the processes of political reform. As a second dimension, it is asked whether there has been a shift in the democracy promotion approach on a continuum between consensual cooptation and coercive intervention. As a third dimension, finally, it is analysed whether the approach has undergone a general intensification of efforts, e.g. whether the approach to democracy promotion has become a more active one. The analysis in this master-thesis comes to the conclusion that since the inception of the ENP the EU is indeed pursuing a slightly more direct and certainly a more active approach to democracy promotion in Morocco, while no significant change can be observed in comparison to the strictly partnership-oriented and consensual approach of the EMP. It can be argued that, under the ENP, relations to Morocco have indeed become somewhat more “political”, although at the same time they are still not pro-actively oriented at a political liberalisation of the political regime. Reforms promoted by the EU in Morocco are modest and largely in line with the reform agenda of the Morrocan government itself – e.g. a still largely authoritarian monarchy. Concrete reform steps directed at an opening of the political space, which is largely reserved to the king and its administration, are neither demanded nor supported by democracy promotion instruments, also under the ENP.
This paper compares police reforms during democratization in Poland, Hungary, and Bosnia-Herzegovina. It analyses the changes to the structure of the democratic control of the police in each reform, paying special attention to the decentralization versus centralization aspect of it. The research question of this paper is: Why are some states decentralizing the democratic control of the police, while others are centralizing it, both with the aim of democratization? The theoretical background of this study are theories about policy diffusion and policy transfer. Therefore this study can be categorized as part of two different research areas. On the one hand, it is a paper from the discipline of International Relations. On the other hand, it is a paper from the discipline of Comparative Politics. The combined attention to international and national factors influencing police reform is reflected by the structure of this paper. Chapter 3 examines police structures and police reforms in established democracies as possible role models for new democracies. Chapter 4 looks at international and transnational actors that actively try to influence police reform. After having examined these external factors, three cases of police reform in new democracies are examined in chapter 5.
