Abstract: | Colleague consultation in professional organizations is both important and commonplace. One consequence of consultation is that some individuals acquire more prominence than others in the work contact networks. The literature suggests that variation in prominence depends on personal characteristics, such as occupation, education, ascribed traits, and activities both inside and outside the organization. Using sociometric data for the staff members of a psychiatric hospital for children, various hypotheses dealing with the effects of personal attributes are examined. An alternative explanation is that social relations within and between organizational subunits influence the likelihood that subunit members will be prominent in the hospital-wide communication network. The analysis indicates that these subunit relations have direct effects on prominence and also mediate the effects of certain personal characteristics. |
