摘要:人际关系是影响社会中个人效能,地位和表现的关键因素。因此,人际关系的建立是社会网络结构分析中的关键问题。在这个演讲中,我们探讨社会网络理论中的三个重要且相互关联的主题:网络的中心/外围的二分结构;网络的动态演化; 和新人在一个网络中的融合。我们着重探讨以下问题:一个新人如何利用信息经纪来整合从外围到中心的网络?我们着重讨论该问题在动态社交网络上的解决方案。该演讲将讨论最近针对于以上问题新的进展。
Interpersonal ties are pivotal to individual efficacy, status and performance in an agent society. The establishment of interpersonal ties thus constitutes a pivotal problem in the structural analysis of social networks. Here we explore three important and interrelated themes in social network theory: the center/periphery partition of the network; network dynamics; and social integration of newcomers. We tackle the question: How would a newcomer harness information brokerage to integrate into a network going from periphery to center? We formulate and investigate the problem for both static and dynamic networks. The talk will survey several recent results obtained towards answering these problems.
