Computers have become commonplace in nearly every setting, from home to office. In addition to their usefulness for managerial tasks, they have the potential to aid the primary decision-making tasks of professional social service workers. The benefits and background of such "expert systems" are explored, and the structure of one experimental consulting program for child welfare workers, PLACECON, is presented.  相似文献

Two questions concerning the location of a single facility by a voting process are investigated for transportation networks:
  • - What is the maximum number of customers located on the network preferring some rival point over a voting solution?
  • - How does the average distance of the customers to the facility increase when a voting location instead of a Weber location is chosen for the facility?
  • Complete answers are given for general networks and for certain planar networks, viz., the so-called generalized cacti.  相似文献

    Abstract Both politicians and voters were asked to predict outcomesof two Oregon ballot measures in 1982. As expected, politicians'predictions always were closer to the mark than voters' were.Further, voters showed stronger signs of wishful thinking (the"Looking-Glass effect") in their predictions than did politicians.Using published preelection polls apparently improved politicians'accuracy in 1982, as well as voters' accuracy in a separate1984 survey. No other sources of data improved predictive accuracy.Findings have implications for theories of representative governmentand are consistent with a new theory of public opinion.  相似文献

    This paper demonstrates the need for a broad array of clinical services in treating the emotionally disturbed, mildly retarded youngster in the foster care system. A hypothesis suggests that cognitive deficits and borderline pathology are interrelated, and that treatment involves modifications of traditional therapeutic techniques. The definition of clinical is expanded to include seemingly concrete and environmental services, in addition to the office therapy session. Finally, some systemic impediments to effective treatment of the population are explored.This paper was completed as a requirement of the Post-Master's Program in Advanced Clinical Social Work of Hunter College School of Social Work.  相似文献

    This article describes the therapeutic use of canines in child welfare work. The chronically rejected child, or those who virtually spend their entire youth in care, tend to develop a withdrawn, depressed, and suspicious posture toward their relations with other people. This ultimately results in their failure to respond to conventional treatment modalities. Under these circumstances, the canine intervention may prove to be a valuable adjunct, helping to develop and to expedite the process of the therapeutic alliance.This article is a revised version of one presented to meet the requirements for the Masters in Social Work Degree from Hunter College School of Social Work.  相似文献
