社会行动者之间的关系纽带的一个核心部分是由共同的隶属关系和事件构成的。共同参与的行动加强了社会行动者之间的个人联系以及共同的价值观和规范，而这些价值观和规范又使界定群体的社会行动模式永久化。因此，对二分网络的研究是社会科学的核心。此外，这些过程的动力学表明，二分网络不应被视为静态结构，而应随着时间的推移进行研究。为了模拟二分网络的演变经验，我们引入了一类模型和贝叶斯推理方案，扩展了以前的随机演员为导向的模型单峰图。对连锁董事的当代研究提供了一个似乎可以合理应用该模型的研究领域。具体而言，我们解决的问题，如何领带的形成，即董事招聘，有助于连锁董事网络的结构特性。对于斯德哥尔摩证券交易所的董事会，我们提出一个多产的领带形成机制是同行推荐。结果表明，这种机制是存在的，产生多个板之间的联锁。
A central part of relational ties between social actors are constituted by shared affiliations and events. The action of joint participation reinforces personal ties between social actors as well as mutually shared values and norms that in turn perpetuate the patterns of social action that define groups. Therefore the study of bipartite networks is central to social science. Furthermore, the dynamics of these processes suggests that bipartite networks should not be considered static structures but rather be studied over time. In order to model the evolution of bipartite networks empirically we introduce a class of models and a Bayesian inference scheme that extends previous stochastic actor-oriented models for unimodal graphs. Contemporary research on interlocking directorates provides an area of research in which it seems reasonable to apply the model. Specifically, we address the question of how tie formation, i.e. director recruitment, contributes to the structural properties of the interlocking directorate network. For boards of directors on the Stockholm stock exchange we propose that a prolific mechanism in tie formation is that of peer referral. The results indicate that such a mechanism is present, generating multiple interlocks between boards.
