This dissertation thesis follows from a wide stream of considerations of the relationship between the mass media, public and politics; in particular detail, it deals with a specific concept which attempts to grasp, model and empirically examine this relationship. The main goals of the thesis can be in short divided into two interrelated areas. The first aim is to introduce the concept of agenda setting to the Czech academic environment, with its theoretical, terminological and research frame for an analysis of relationships between the mass media content, dynamics of public opinion, and the political sphere. The second aim is to analyze how agenda setting processes are theoretically grounded and studied in the Czech social studies. The theoretical part of the thesis is structured according to two perspectives: diachronic and synchronic. In the diachronic perspective, I try to grasp the social context and historical origins of agenda-setting as a concept, its development, main trends, and developmental lines. This way, I move forward to the synchronic perspective and describe academic grounding of agenda-setting; I give a detailed analysis of the present level of the agenda-setting research and the main research areas through available classifications. The second fundamental area of the dissertation consists...

A recent meta-analysis of Anderson and colleagues (2010) shows that violent behavior in computer games promotes violent behavior in real-life and inhibits prosocial behavior. A couple of studies conducted by Greitemeyer and Osswald (2010) lead to the conclusion that helping behavior in computer games furthers helping behavior in real-life. There exist no studies examining the combined effect of violence and helping in computer games, although this combination is typical for violent video games (Anderson et al., 2010). In violent RPGs, a lot of tasks consist of helping someone by using violence. The present study addresses this issue and bridges the current empirical gap by investigating if violent emergency assistance furthers helping behavior and/or violent behavior in real-life. To accomplish that, the role-playing game “Oblivion” was modified to create four different experimental conditions: (1) violent emergency assistance, (2) killing, (3) helping, and (4) treasure hunting. Comparing these conditions, violent emergency assistance seemingly reduces helping behavior in real-life and at the same time furthers violent behavior. The results are in unison with the moral management model (Hartmann & Vorderer, 2010; Hartmann, in press), which is based on Banduras Theory of Moral Disengagement (Bandura, 2002).
