  abstract  = {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.},

  abstract  = {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.},

  abstract  = {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.},
