This special issue on advancing interdisciplinary collaboration between computer scientists and social scientists documents the joint results of the international Lorentz workshop, "Interdisciplinary Insights into Group and Team Dynamics," which took place in Leiden, The Netherlands, July 2016. An equal number of scholars from social and computer science participated in the workshop and contrib...

E work groups engage in external knowledge sharing—the exchange of information, know-how, and feedback with customers, organizational experts, and others outside of the group. This paper argues that the value of external knowledge sharing increases when work groups are more structurally diverse. A structurally diverse work group is one in which the members, by virtue of their different organiza...

Three studies were conducted to test the hypothesis that judgments of average females' attractiveness or dating desirability will be adversely affected by exposing judges to extremely attractive prior stimuli (i.e., judgments will show a "contrast effect"). Study 1 was a field study in which male dormitory residents watching a popular TV show, whose main characters are three strikingly attracti...

Studies in social network analysis consider the behavior of a group to be equivalent to the “sum” of individual behaviors. However, a group has to be considered as a complex system where emerging phenomena can appear. In this paper, a formalism is proposed to resolve this problematic by modeling groups in social networks using pretopology as a generalization of the graph theory. We also give an...

In many social science settings, the data available for analysis span multiple groups. In these settings it is often plausible that any statistical model we might fit to the data will fit need to flexible, so as to capture variation across the groups, typically accomplished by letting some or all of the parameters vary across the groups. Examples include survey data gathered over a set of locat...

Four studies examined children's (ages 3-10, Total N=235) naïve theories of social groups, in particular, their expectations about how group memberships constrain social interactions. After introduction to novel groups of people, preschoolers (ages 3-5) reliably expected agents from one group to harm members of the other group (rather than members of their own) but expected agents to help membe...

This study focuses on modern representations of race on the Internet. As race continues to be used as a meaningful category for understanding the social world, Internet-based displays of racial membership reflect the ongoing significance of race. Concurrent with Facebook’s growth in popularity has been the development in ways that racial identity has been expressed online. While Facebook has be...

An important factor in seizing these opportunities is developing trust and creating reputation among consumers. This qualitative study examines how a group of Australian small business managers utilize social media websites to connect...
