  abstract  = {Inheritance is an important and widely spread concept enabling the elegant expression of hierarchy in object-oriented software programs or models. It has been defined for graphs and graph transformations enhancing the applicability of this formal technique. Up to now, for the analysis of transformations with inheritance a flattening construction has been used, which yields all the well-known results for graph transformation but results in a large number of graphs and rules that have to be analyzed. In this paper, we introduce a new category of typed attributed graphs with inheritance. For the detection of conflicts between graph transformations on these graphs, the notion of abstract critical pairs is defined. This allows us to perform the analysis on polymorphic rules and transformations without the need for flattening, which significantly increases the efficiency of the analysis and eases the interpretation of the analysis results. The new main result is the Local Confluence Theorem for typed attributed graph transformation with inheritance using abstract critical pairs. All constructions and results are demonstrated on an example for the analysis of refactorings. (C) 2012 Elsevier B.V. All rights reserved.},

  abstract  = {As the number of rich people in Germany increases, it becomes more and more relevant to ask how they spend their wealth, because among other aspects being rich can be legitimized by social commitment. For example, responsibility can be shown by financial commitment or volunteering. Academic results not only show a rising number of people that are philanthropically active but also an increase in philanthropic behavior in the last two decades. Unlike it is stated in the American literature, social commitment of wealthy people has not yet gained currency in the German literature. In addition, it is little known about inheritance to society beside family transfers after death. Based on the data of the study "Vermogen in Deutschland" (ViD) (Wealth in Germany) the paper discusses these questions for the year 2008. The results reveal a considerably above-average commitment of wealthy households and people. Moreover, 41 \% of all respondents plan to fund a part of their wealth for public purposes and charity.},
