We combine the logic of multi-mode networks developed in Fararo and Doreian (1984) with Newman's (2006) spectral partitioning of graphs into communities. The resulting generalization of spectral partitioning provides a simple, elegant, and useful tool for discovering the community structure of multi-mode graphs. We apply the generalized procedure to a(More)
In a driving simulator experiment, male and female college students received turn-by-turn driving directions and cognitive tasks while interacting with an experimenter via an audio communication system. In an Enhanced condition (n = 29), lower speech frequencies (containing the speech fundamental frequency) were routed to participants' left ears (with right(More)
Building on a recent theoretical development in the field of sociological social psychology, we develop a formal mathematical model of social influence processes. The extant theoretical literature implies that factions and status should have non-linear effects on social influence, and yet these theories have been evaluated using standard linear statistical(More)
Justice research has evolved by elucidating the factors that affect justice evaluations, as well as their consequences. Unfortunately, few researchers have paid attention to the pattern of rewards over time as a predictor of justice evaluations. There are two main objectives of this research. First, it aims to test the effect of reward stability on justice(More)
Dynamic networks have been shown to increase cooperation, but prior findings are compatible with two different mechanisms for the evolution of cooperation. It may be that dynamic networks promote cooperation even in networks composed entirely of egoists, who strategically cooperate to attract and maintain profitable interaction partners. Alternatively,(More)
