Nachdem im Rahmen eines studentischen Projektseminars unter der Leitung von Prof. Dr. Jochen Franzke und Prof. Dr. Heinz Kleger im Winter 2005/2006 die Positionen der organisierten Potsdamer B{\"u}rgerschaft zum B{\"u}rgerhaushalt untersucht worden waren, stand bei der Fortsetzung des Projektseminars im Sommer 2007 die Haltung der Potsdamer B{\"u}rger1 zu diesem Thema im Mittelpunkt unseres Interesses. Insgesamt 564 Potsdamer wurden dazu in den einzelnen Sozialr{\"a}umen der Stadt befragt. Ziel war es, herauszufinden, inwieweit die einzelnen B{\"u}rger der Stadt Potsdam bereits mit dem Konzept des B{\"u}rgerhaushalts vertraut waren, wie groß deren Bereitschaft zur Mitwirkung an diesem Projekt war und welche Wirkungen die B{\"u}rger vom B{\"u}rgerhaushalt erwarten.

  abstract  = {Since the end of the Apartheid international tourism in South Africa has increasingly gained importance for the national economy. The centre of this PKS issue's attention is a particular form of tourism: Township tourism, i.e. guided tours to the residential areas of the black population. About 300,000 tourists per year visit the townships of Cape Town. The tours are also called Cultural, Social, or Reality Tours. The different aspects of township tourism in Cape Town were subject of a geographic field study, which was undertaken during a student research project of Potsdam University in 2007. The text at hand presents the empirical results of the field study, and demonstrates how townships are constructed as spaces of tourism.},

For large-scale models, efficiency is essential in this respect. In this paper, we present an improved model synchronization algorithm based on triple graph grammars that is highly efficient and, therefore, can also synchronize large-scale models sufficiently fast. We can show, that the overall algorithm has optimal complexity if it is dominating the rule matching and further present extensive measurements that show the efficiency of the presented model transformation and synchronization technique.},

  abstract  = {Modern acquisition of seismic data on receiver networks worldwide produces an increasing amount of continuous wavefield recordings. Hence, in addition to manual data inspection, seismogram interpretation requires new processing utilities for event detection, signal classification and data visualization. Various machine learning algorithms, which can be adapted to seismological problems, have been suggested in the field of pattern recognition. This can be done either by means of supervised learning using manually defined training data or by unsupervised clustering and visualization. The latter allows the recognition of wavefield patterns, such as short-term transients and long-term variations, with a minimum of domain knowledge. Besides classical earthquake seismology, investigations of temporal patterns in seismic data also concern novel approaches such as noise cross-correlation or ambient seismic vibration analysis in general, which have moved into focus within the last decade. In order to find records suitable for the respective approach or simply for quality control, unsupervised preprocessing becomes important and valuable for large data sets. Machine learning techniques require the parametrization of the data using feature vectors. Applied to seismic recordings, wavefield properties have to be computed from the raw seismograms. For an unsupervised approach, all potential wavefield features have to be considered to reduce subjectivity to a minimum. Furthermore, automatic dimensionality reduction, i.e. feature selection, is required in order to decrease computational cost, enhance interpretability and improve discriminative power. This study presents an unsupervised feature selection and learning approach for the discovery, imaging and interpretation of significant temporal patterns in seismic single-station or network recordings. In particular, techniques permitting an intuitive, quickly interpretable and concise overview of available records are suggested. For this purpose, the data is parametrized by real-valued feature vectors for short time windows using standard seismic analysis tools as feature generation methods, such as frequency-wavenumber, polarization, and spectral analysis. The choice of the time window length is dependent on the expected durations of patterns to be recognized or discriminated. We use Self-Organizing Maps (SOMs) for a data-driven feature selection, visualization and clustering procedure, which is particularly suitable for high-dimensional data sets. Using synthetics composed of Rayleigh and Love waves and three different types of real-world data sets, we show the robustness and reliability of our unsupervised learning approach with respect to the effect of algorithm parameters and data set properties. Furthermore, we approve the capability of the clustering and imaging techniques. For all data, we find improved discriminative power of our feature selection procedure compared to feature subsets manually selected from individual wavefield parametrization methods. In particular, enhanced performance is observed compared to the most favorable individual feature generation method, which is found to be the frequency spectrum. The method is applied to regional earthquake records at the European Broadband Network with the aim to define suitable features for earthquake detection and seismic phase classification. For the latter, we find that a combination of spectral and polarization features favor S wave detection at a single receiver. However, SOM-based visualization of phase discrimination shows that clustering applied to the records of two stations only allows onset or P wave detection, respectively. In order to improve the discrimination of S waves on receiver networks, we recommend to consider additionally the temporal context of feature vectors. The application to continuous recordings of seismicity close to an active volcano (Mount Merapi, Java, Indonesia) shows that two typical volcano-seismic events (VTB and Guguran) can be detected and distinguished by clustering. In contrast, so-called MP events cannot be discriminated. Comparable results are obtained for selected features and recognition rates regarding a previously implemented supervised classification system. Finally, we test the reliability of wavefield clustering to improve common ambient vibration analysis methods such as estimation of dispersion curves and horizontal to vertical spectral ratios. It is found, that in general, the identified short- and long-term patterns have no significant impact on those estimates. However, for individual sites, effects of local sources can be identified. Leaving out the corresponding clusters, yields reduced uncertainties or allows for improving estimation of dispersion curves.},

  abstract  = {F{\"u}r den internationalen Vergleich von Gesellschaften wird ein System gesellschaftlicher Dauerbeobachtung vorgeschlagen, indem aufgrund einer Auseinandersetzung mit der sozialphilosophischen Diskussion acht Performanzkriterien f{\"u}r den internationalen Vergleich von Lebensbedingungen entwickelt werden: Wohlstand und Wachstum; {\"o}kologische Nachhaltigkeit; Innovation; soziale Sicherung durch Unterst{\"u}tzungsleistungen im Risikofall sowie vorsorgend durch Bildungsinvestitionen; Anerkennung der Besonderheiten (Frauenfreundlichkeit und Migrantenfreundlichkeit); Gleichheit der Teilhabe; soziale Integration; Autonomie („freedom of choice and capabilities"). In unserem Ansatz gehen wir nicht von einem einheitlichen Pfad der Modernisierung in Richtung Wachstum, Partizipation und Inklusion aus, sondern unterscheiden in Erweiterung der „drei Welten des Wohlfahrtskapitalismus" von Esping-Andersen (1990) (mindestens) f{\"u}nf verschiedene institutionelle Entwicklungspfade der Modernisierung: Der sozialdemokratischuniversalistische Pfad, der wirtschaftsliberale Pfad, der Status-konservierende Pfad, der „familistische" Pfad und die Entwicklung der Gruppe der exsozialistischen L{\"a}nder, die sich in einem Prozess der Ausdifferenzierung befinden. Zur Analyse der Sozialstrukturen werden als Modelle sozialer Lagen ber{\"u}cksichtigt: Marx, Weber, Roemer/Wright; soziale Schichten, berufliche Lagen, Goldthorpe-Modell; Bourdieu, Vester, Hradil. Als Anwendungsbereiche werden behandelt: Dienstleistungsgesellschaften und Erwerbst{\"a}tigkeit, Bildung; Wohlfahrtsregime und soziale Sicherung; Wohlstand, Einkommen, Verm{\"o}gen und Armut; soziale Mobilit{\"a}t; soziale Ungleichheiten zwischen Frauen und M{\"a}nnern; Bev{\"o}lkerungsstruktur und Lebensformen; Lebensstile; Individualisierung und ihre Gegenbewegungen; zusammenfassender Vergleich von Lebensbedingungen in verschiedenen L{\"a}ndern und Wohlfahrtsregimen.},
