In the 1990s, the integrity and performance of nonprofit organizations in the United States have come increasingly under attack, and there are new calls to hold nonprofit organizations more accountable for their behavior and performance. This article reports on a study of the organizational structures of national nonprofit associations and asks how these umbrella organizations can help to self-regulate the sector through appropriate checks and balances between the national organization and local affiliates. The authors identify a number of differences in how associations with alternative structures hold local affiliates and national organizations responsible for their performances, and they conclude that structure is an avenue of self-regulation for nonprofit organizations deserving further attention.  相似文献

This paper argues that the presence of competitive, as opposed to monopsonistic, labor markets should reduce the level of entry discrimination. For those teams that have a “taste” for discrimination, competitive labor markets increase the cost of discriminating, because competition bids-up the salaries of the preferred players, relative to the salaries of the non-preferred players. The paper empirically tests this notion by examining the impact on French Canadian players of the short-lived World Hockey Association (WHA).  相似文献

Summary A model is developed for a triple catch marking experiment on two areas with migration between the two areas and death or emigration occurring. Estimates of the parameters of the model are derived. Some of these estimates are shown to be suitable even under certain restrictions on migration (e.g. animals may be restricted to a single transfer in the course of the experiment). Variances of the estimates were not derived but some rules were developed, based on computer simulations, to guide the experimenter in planning experiments and in judging the precision of his estimates.  相似文献

Current biomedical research on sex selection techniques may soon offer couples the opportunity to choose the sex of their children with greater certainty. A technique planned for marketing by mid-1978 can increase the probability of bearing a son to as much as 0.90. However, couples who wish to improve their chances of bearing a daughter have no such opportunity. The purpose of this paper is two-fold. First, a decision-making model is provided which describes how couples should choose among alternative sex-selection methods so as to maximize the probability of bearing their desired number of sons and daughters. Second, the effect of the widespread use of sex-selection techniques on the population sex ratio is explored. It is shown that even if populations have unbiased sex preferences, or sex preferences biased towards daughters, the use of biased sex-selection technologies may result in very high population sex ratios.  相似文献

This article identifies and lists the problems of children with complex medical conditions and/or complex home health case needs. Five categories of seriously chronically ill children are identified and programs to meet their needs discussed. The authors believe many of these children could benefit from foster home placements; they discuss one project in which there is collaboration between a pediatric medical center and a social service agency.  相似文献

THE GANDHI TECHNIQUE: A NEW PROCEDURE FOR INTRACTABLE PROBLEMS   总被引:1,自引:1,他引:0  
Most therapists eventually encounter a client with intractable difficulties. Such difficulties have various origins. The Gandhi Technique is a simple, dramatic and seemingly effective procedure to resolve intractable difficulties. This paper describes the technique and its application in three different cases. The paper also discusses several theories which may account for the efficacy of the technique. The authors propose the technique as a procedure that can be employed to resolve many kinds of problems, regardless of their origin.  相似文献

The average person-per-room ratio in Australia is low by international standards. But there are marked inequalities in the distribution of dwelling space, and the question is examined of whether the current allocation of dwelling space within the housing system constitutes a social problem on a national scale. The examination is based partly on an analysis of published census data, partly on existing literature, and partly on raw data derived from two recent housing surveys.  相似文献
