Partnership ties shape friendship networks through different social forces. First, partnership ties drive clustering in friendship networks: individuals who are in a partnership tend to have common friends and befriend other couples. Second, partnership ties influence the level of homophily in these emerging friendship clusters. Partners tend to be similar in a number of attributes (homogamy). If one partner selects friends based on preferences for homophily, then the other partner may befriend the same person regardless of whether they also have homophilic preferences. Thus, two homophilic ties emerge based on a single partner’s preferences. This amplification of homophily can be observed in many attributes (e.g., ethnicity, religion, age). Gender homophily, however, may be de-amplified, as the gender of partners differs in hetero-sexual partnerships. In our study, we follow dynamic friendship formation among 126 individuals and their cohabiting partners in a university-related graduate housing com-munity over a period of nine months (N = 2,250 self-reported friendship relations). We find that partnership ties strongly shape the dynamic process of friendship formation. They are a main driver of local network clustering and explain a striking amount of homophily.

The Heider balance is a sociological problem of a division of a community into hostile groups, where all interpersonal relations within the groups are friendly and all relations between the members of different groups are hostile. Here we trace how the research of the process of attaining the Heider balance has moved during last ten years from a psycho-social to a computational problem. PACS numbers: 87.23.Ge, 07.05.Tp

Is social network analysis just measures and methods with no theory? We attempt to clarify some confusions, address some previous critiques and controversies surrounding the issues of structure, human agency, endogeneity, tie content, network change, and context, and add a few critiques of our own. We use these issues as an opportunity to discuss the fundamental characteristics of network theory and to provide our thoughts on opportunities for future research in social network analysis. 3

We model a community of individuals whose relationships are governed by the rules of the so-called Heider balance theory, but modified to address the impact of tolerating intolerant individuals. To consider tolerance toward a different group, the elements are assigned one of the two flags, A or B, and the elements of each group can be tol-erant or intolerant. Two additional parameters, p and q, respectively, characterize the propensity of elements to cooperate and the propensity of tolerants to reject intol-erant attitudes. We find that (1) parameter q does not affect the degree of conflict at the micro level, but has an important influence on the degree of conflict in the whole system; (2) segregation into two cliques occurs whenever there exists intolerants in both groups; (3) when intolerants are present in only one of the groups, segregation can be avoided for appropriate combinations of parameters p and q that depend on the fraction of intolerants and the size of the groups; (4) as the size of the system increases, two balanced solutions dominate: segregation into two cliques or the iso-lation of intolerants; and (5) endemic partially balanced configurations are observed in large systems.

Evolution is well underway in the area of teams. As Tannenbaum,Mathieu, Salas, and Cohen (2012) aptly convey, today’s teams are increasingly complex! Teams are no longer relatively straightforward extensions of individually-based jobs; rather, teams are increasingly capitalizing on techno-logical advances joining together larger, more diverse, more highly specialized, and often distributed sets of individuals to tackle Correspondence concerning this article should be addressed to Toshio Murase.

In international politics, states learn from the behavior of other states, includ-ing the reputations states form through their actions in the international system. I develop a model of how states process this information and examine how this learning affects international conflict. The model builds off of cognitive balance theory and foreign policy learning models, and breaks new ground in its ability to provide a contextual assessment of reputation in world politics. I then inves-tigate whether a dyad is more likely to experience conflict if at least one of the states has a reputation for hostility. This hypothesis is tested empirically across all dyads in the international system from 1817-2000. The results indicate that states do engage in this learning behavior, and that the information generated by extra-dyadic interaction of states has a significant bearing upon the likelihood of dyadic conflict. ∗A previous draft of this paper was presented at the 2003 Annual Meeting of the American
