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.

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.
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.

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.
