The talk will focus on a few central problems in Game Studies: The question of where to locate game meaning, game defintions and how to avoid them, and the conundrum of games vs stories. In all these problems, the choice of ludic perspective (e.g. are games artifacts, systems or activities?) limits our ability to discuss games across disciplinary boundaries. What is needed is a metaperspective that will offer the field a chance to move on.

Service-oriented modeling employs collaborations to capture the coordination of multiple roles in form of service contracts. 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.
The conidial stage and chasmothecia of Golovinomyces orontii have been found in Germany on cultivated Limnanthes douglasii. A powdery mildew anamorph found in the Netherlands on Malva alcea agrees morphologically with the Oidium of the latter species as well. Golovinomyces sp. (anamorph) on Parthenium integrifolium is described and discussed. Erysiphe sp. has been found in Germany on Acer opalus, and E. magnifica is recorded from Germany and Switzerland on Magnolia spp. Oidium passiflorae is new to Switzerland. An Oidium morphologically agreeing with the anamorph of Podosphaera aphanis has recently been collected on Exacum macranthum cultivated in a greenhouse, and conidiophores and conidia of a species of Podosphaera sect. Sphaerotheca subsect. Magnicellulatae (P. fusca complex) on Phlox paniculata and Polemonium caeruleum have been found in Germany.
Model-driven software development requires techniques to consistently propagate modifications between different related models to realize its full potential. 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.

“The UN Peacebuilding Commission – Lessons from Sierra Leone” by political scientist Andrea Iro is an assessment of the United Nations Peacebuilding Commission (PBC) and the United Nations Peacebuilding Fund (PBF) by analysing their performance over the last two years in Sierra Leone, one of the first PBC focus countries. The paper explores the key question of how the PBC/PBF’s mandate has been translated into operational practice in the field. It concludes that though the overall impact has been mainly positive and welcomed by the country, translating the general mandate into concrete activities remains a real challenge at the country level.
In 1993, the Parliament of the World's Religions endorsed the "Declaration toward a Global Ethic" composed by Hans Küng. In it, representatives from all the world's religions agreed on principles for a global ethic and committed themselves to directives of nonviolence, respect for life, solidarity, a just economic order, tolerance, and equal rights and partnership between men and women. But the declaration was just the first step. In this impressive volume, Hans Kueng, probably the most famous living Roman Catholic theologian, and Rabbi Walter Homolka, head of Germany's Abraham Geiger rabbinical seminary and distinguished professor, draw on the Jewish tradition to show the riches that Judaism can offer people of all faiths and nonbelievers in achieving these directives. Presenting key sacred texts and theological writings, the authors make the case for binding values and basic moral attitudes that can be found in Judaism's universal message of a better world. Exploring Judaism's focus on ethical conduct over declarations of faith, the authors show that making ethical decisions is indispensable in an ever-changing world.
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.
Business process management experiences a large uptake by the industry, and process models play an important role in the analysis and improvement of processes. While an increasing number of staff becomes involved in actual modeling practice, it is crucial to assure model quality and homogeneity along with providing suitable aids for creating models. In this paper we consider the problem of offering recommendations to the user during the act of modeling. Our key contribution is a concept for defining and identifying so-called action patterns - chunks of actions often appearing together in business processes. In particular, we specify action patterns and demonstrate how they can be identified from existing process model repositories using association rule mining techniques. Action patterns can then be used to suggest additional actions for a process model. Our approach is challenged by applying it to the collection of process models from the SAP Reference Model.

This paper deals with Kiezdeutsch, a way of speaking that emerged among adolescents in multiethnic urban neighbourhoods of Germany. We show that, in Kiezdeutsch, we find evidence for both grammatical reduction and new developments in the domain of information structure, and hypothesise that this points to a systematic interaction between grammar and information structure, between weakened grammatical constraints and a more liberal realisation of information-structural preferences. We show that Kiezdeutsch can serve as an interesting test case for such an interaction, that this youth language is a multiethnolect, that is, a new variety that is spoken by speakers from a multitude of ethnic backgrounds, including German, and forms a dynamic linguistic system of its own, thus allowing for systematic developments on grammatical levels and their interfaces with extragrammatical domains.
Design and Implementation of service-oriented architectures imposes a huge number of research questions from the fields of software engineering, system analysis and modeling, adaptability, and application integration. Component orientation and web services are two approaches for design and realization of complex web-based system. Both approaches allow for dynamic application adaptation as well as integration of enterprise application. Commonly used technologies, such as J2EE and .NET, form de facto standards for the realization of complex distributed systems. Evolution of component systems has lead to web services and service-based architectures. This has been manifested in a multitude of industry standards and initiatives such as XML, WSDL UDDI, SOAP, etc. All these achievements lead to a new and promising paradigm in IT systems engineering which proposes to design complex software solutions as collaboration of contractually defined software services. Service-Oriented Systems Engineering represents a symbiosis of best practices in object-orientation, component-based development, distributed computing, and business process management. It provides integration of business and IT concerns. The annual Ph.D. Retreat of the Research School provides each member the opportunity to present his/her current state of their research and to give an outline of a prospective Ph.D. thesis. Due to the interdisciplinary structure of the Research Scholl, this technical report covers a wide range of research topics. These include but are not limited to: Self-Adaptive Service-Oriented Systems, Operating System Support for Service-Oriented Systems, Architecture and Modeling of Service-Oriented Systems, Adaptive Process Management, Services Composition and Workflow Planning, Security Engineering of Service-Based IT Systems, Quantitative Analysis and Optimization of Service-Oriented Systems, Service-Oriented Systems in 3D Computer Graphics, as well as Service-Oriented Geoinformatics.
