This paper shows how the concept of an incidence matrix of communications can be used to define the entropy of a finite scheme. The properties of the entropy function are examined and the function is found to be best interpreted as a total expected participation index. Data is presented showing the relationship between structural centrality and the new total expected participation index. In general, as the network becomes more centralized the smaller the value of the participation index and as the network becomes more structurally decentralized the greater the participation index.This research was supported in part by Ford Foundation Grant 1-40055 to the Graduate School of Industrial Administration at Carnegie Institute of Technology for Research in Organizational Behavior.The author wishes to acknowledge the aid of Terry B. Marbach in the preparation of data. 相似文献

When 72 male students in a southern theological institution were compared by the manner in which they intended to fulfill their religious vocation (i.e., as missionaries, pastors, or religious education workers), a homogeneity of personality behavior was observed on each of 16 factors. The total sample, however, was reported to be substantially and significantly different from the general population on four factors. No significant difference was reported among the three groups in their need for social approval as measured by the Marlowe-Crowne SDS. 相似文献

Factual and subjective data gathered from counseling centers in 36 major universities is presented to show present conditions, emphasis, and needs of the future. Data are presented showing ratios of counselors to students, budget allotments, strengths, specific weaknesses, etc. Counseling facilities, services provided, emphasis, communications and plans for expansion are dealt with individually. Less than half the centers were meeting student needs and a majority indicated a shortage of professional staff, particularly those competent to do personal adjustment counseling. 相似文献
