First it gives an account of the existing coordination patterns, second it analyses changes within these coordination patterns over time and finally it asks, whether these changes can be attributed to an intentional institutional design. To answer this set of questions, we introduce an institutional policy analytic perspective to the study of central government change. This perspective focuses on central actors, interests, strategic motivations and the degree of the actors reflexivity as a promoter of intentional institutional change in government coordination. The empirical analysis shows the prevalence of negative coordination as the dominant pattern of coordination in all three countries. However, country-specific constitutional and political traditions result in a variety of different coordination techniques actually used. The paper concludes by identifying three different patterns of change, depending on the degree of change and the reflexivity involved : "fragmented institutional politics" in Denmark, "policy-driven institutional politics" in Germany and "adaptive and symbolic institutional politics" in the case of Sweden.}, language = {de} } @book{BauerErnstFroehlichetal.2006, author = {Bauer, Steffen and Ernst, Ren{\´e}e and Fr{\"o}hlich, Manuel and H{\"a}ußler, Ulf and Loges, Bastian and Menzel, Ulrich and Schopp-Schilling, Hanna Beate and Weinz, Irene}, title = {Chancen f{\"u}r eine Reform der Vereinten Nationen?}, series = {Potsdamer UNO-Konferenzen}, journal = {Potsdamer UNO-Konferenzen}, number = {6}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-937786-97-1}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-90240}, publisher = {Universit{\"a}t Potsdam}, pages = {134}, year = {2006}, abstract = {Am 24. und 25.

The referendum (2008), to gain the right to dissolve the Parliament by the people, initiated by the Trade Unions can be assessed as a sign that there is something on the move. This paper is trying to give an impression of the situation of the civil society in terms of participation in the decision- making process. Hereby the focus lays on NGOs: What is the legal base and which problems do they face. To learn more about the situation interviews were organized with representatives of NGOs from different sectors like community development; Social inclusion; advocating gender issues as well as environment and sustainable development. As a result of the research it can be said that the civil society made some steps forward but it is still struggling with a high level of corruption, lack of interested from the elite and the ordinary people and the insecure financial state.}, language = {en} } @book{OPUS4-6813, title = {Cloud security mechanisms}, number = {87}, editor = {Neuhaus, Christian and Polze, Andreas}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-281-0}, issn = {1613-5652}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-68168}, publisher = {Universit{\"a}t Potsdam}, pages = {78}, year = {2014}, abstract = {Cloud computing has brought great benefits in cost and flexibility for provisioning services.

The rule-based formalism of probabilistic timed graph transformation systems is a suitable choice when the models representing states of the system can be understood as graphs and timed and probabilistic behavior is important. However, model checking PTGTSs is limited to systems with rather small state spaces. We present an approach for the analysis of large scale systems modeled as probabilistic timed graph transformation systems by systematically decomposing their state spaces into manageable fragments. To obtain qualitative and quantitative analysis results for a large scale system, we verify that results obtained for its fragments serve as overapproximations for the corresponding results of the large scale system. Hence, our approach allows for the detection of violations of qualitative and quantitative safety properties for the large scale system under analysis. We consider a running example in which we model shuttles driving on tracks of a large scale topology and for which we verify that shuttles never collide and are unlikely to execute emergency brakes. In our evaluation, we apply an implementation of our approach to the running example.}, language = {en} } @book{OPUS4-3143, title = {Conceptual architecture patterns : FMC-based representations}, editor = {Gr{\"o}ne, Bernhard and Keller, Frank}, isbn = {978-3-935024-98-3}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-33173}, publisher = {Universit{\"a}t Potsdam}, year = {2004}, abstract = {This document presents the results of the seminar "Coneptual Arachitecture Patterns" of the winter term 2002 in the Hasso-Plattner-Institute.

In case of dynamic collaborations the roles may join and leave the collaboration at runtime and therefore complex structural dynamics can result, which makes it very hard to ensure their correct and safe operation. We present in this paper our approach for modeling and verifying such dynamic collaborations. Modeling is supported using a well-defined subset of UML class diagrams, behavioral rules for the structural dynamics, and UML state machines for the role behavior. To be also able to verify the resulting service-oriented systems, we extended our former results for the automated verification of systems with structural dynamics [7, 8] and developed a compositional reasoning scheme, which enables the reuse of verification results. We outline our approach using the example of autonomous vehicles that use such dynamic collaborations via ad-hoc networking to coordinate and optimize their joint behavior.}, language = {en} }
