Building Collegial Information Networks: A Theory of Advice Network Generation
提出一个理论，预测人们在需要建议时会联系谁，权衡预期知识价值与获取成本，并在信息不足时依赖可及性和分享意愿。
The theory of network generation I present predicts actor selection and retention in forming an advice network. The research question explored is whom do people contact when needing advice? The theory posits that the advice seeker, when possessing rich information on potential alters, decides whom to contact by trading off expected knowledge value versus the cost of obtaining it. In the contact information poor case, alter selection antecedents are the potential contact's accessibility and perceived willingness to share advice.
