Group behavior is an important feature of conflict scenarios. Often such groups are chaotically organized, but their ideals are sociologically embedded across members such that the group has expected behavior that can represent a major threat. Therefore being able to model the evolution of groups on a generative basis, to anticipate their possible mutation, is valuable. However this is complex ...

The idea that cooperative groups out-compete less cooperative groups has been proposed as a theoretical possibility for the evolution of cooperation through cultural group selection. Previous studies have found an association between increased cooperation and exposure to inter-group violence, but most have not been able to identify the specific target of cooperation and are based on correlation...

We consider a mathematical model for the group size determination by the intra-reactions, self-growth, ostracism and fission within a group, and by the inter-reactions, immigration and fusion between two groups. In some group reactions, a conflict between two groups occurs about the reaction to change the group size. We construct a mathematical model to consider such conflict, taking into accou...

The origin of cooperation is a central problem in evolutionary biology and social science. Cultural group selection and parochial altruism are popular but controversial evolutionary explanations for large-scale cooperation. Proponents of the cultural group selection hypothesis argue that the human tendency to conform—a consequence of our reliance on social learning— maintained sufficient betwee...

Today, work-family issues have gained special importance to employees, families, and organizations. Work–family conflict is an inter–role conflict in which work and family demands are mutually incompatible and creates stress and numerous problems. So, the aim of this study was to examine the effect of work–family conflict management model in life satisfaction of male employees...

The literature on "ethnic conflict" tends to focus solely on external sources of such conflict. But this unquestioning focus on ethnic conflict as due to factors in the relationship between "ethnic groups” or their elites may at times be misleading. Drawing on a critique of conflict theory as developed in the field of international relations, I point out the conceptual and methodological proble...

We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of socio-political conflict. The theoretical prediction is that conflict expenditures are independent of group size and of whether punishment is available or not. We find, first, that conflict expenditures of groups are s...
