Deviant Group Membership – Joining, Leaving, and Behavior in Criminal Groups

Cult membership: What factors contribute to joining or leaving?

We assumed that, as in the case of addiction disorders, former cult members exhibit vulnerability and protective factors for cult commitment and membership. Thus, the aim of our study was to identify vulnerability factors that are involved in the commitment and in the retention in the group, as well as protective factors that are involved in the departure. We interviewed 31 former cult members,...

Individual Behavior and Group Membership

People who are members of a group, and identify with it, behave differently from people in isolation. The way in which the behavior differs depends in subtle ways from the way in which the nature of the group is perceived, as well as its salience, and also on the way in which people perceive that group membership and observation affects the behavior of others. We study these hypotheses in a str...

Individual Behavior and Group Membership 1

People who are members of a group, and identify with it, behave differently from people in isolation. The way in which the behavior differs depends in subtle ways from the way in which the nature of the group is perceived, as well as its saliency, and also on the way in which people perceive that the behavior of others is affected by the group. We study these hypotheses in a strategic experimen...

Group Membership for Groups with Primitive Orbits

This paper considers a permutation group G = 〈S〉 of degree n with t orbits such that the action on each orbit is primitive. It presents a O(tn2 logc(n)) time Monte Carlo group membership algorithm for some constant c. The algorithm is notable for its use of a new theorem showing how to find O(t log n) generators in O (̃|S|n) time under a more general form of the above hypotheses. The algorithm r...
