Summary A study is reported of the perceived effectiveness of teamsof social workers and their managers. Prior studies are reviewedand shown to give disproportionate emphasis to the supervisionelement in the manager's task. It is shown that in the sampleof teams studied the correlates of perceived team effectivenesswere quite different in area teams from those found in socialwork teams. Social work teams required a manager who was primarilysupportive, whereas in area teams the manager's role was foundto be less important than were group process variables. 相似文献

This paper explores how some widely studied classes of nonexpected utility models could be used in dynamic choice situations. A new "sequential consistency" condition is introduced for single-stage and multi-stage decision problems. Sequential consistency requires that if a decision maker has committed to a family of models (e.g., the multiple priors family, the rank-dependent family, or the betweenness family) then he use the same family throughout. Conditions are presented under which dynamic consistency, consequentialism, and sequential consistency can be simultaneously preserved for a nonexpected utility maximizer. An important class of applications concerns cases where the exact sequence of decisions and events, and thus the dynamic structure of the decision problem, is relevant to the decision maker. It is shown that for the multiple priors model, dynamic consistency, consequentialism, and sequential consistency can all be preserved. The result removes the argument that nonexpected utility models cannot be consistently used in dynamic choice situations. Rank-dependent and betweenness models can only be used in a restrictive manner, where deviation from expected utility is allowed in at most one stage. 相似文献

Summary A small scale pilot study was conducted in two area teams andfour part-time GP attachment schemes to test the use of a psychiatricscreening instrument (GHQ28) and social assessments. The instrumentswere administered at case allocation and again at three months.Few clinical and social changes were observed in the short term.It was found that 27 out of 40 cases (68%) were identified bythe psychiatric screening instruments as probable cases of minordisorder, on both occasions, and that a further seven clientscould have had a transient disturbance. On the basis of theseresults it was felt that a larger two-stage enquiry was warranted,and necessary, before definite conclusions could be drawn. 相似文献

A serious gap is emerging between what is espoused as total quality management and what is actually being implemented. Examples of actual implementation failures are given. In addition to affecting the offending firms, these gaps threaten the viability of the quality management movement in the United States. Their causes and appropriate counter measures are worthy topics for research. 相似文献
