Abstract

The results of a study of social networking by professors’ co-memberships in library and information science PhD juries between 1993 and 2006 are presented. Degree reduction and k-core methods are used to extract sub-networks and a Ward’s hierarchical cluster analysis is performed. The resulting network identifies five classes, whose members are actors occupying similar social positions, and at the same time different mechanisms, based mainly in similarity and physical proximity, are proposed from the interpretative point of view.
