Rubinstein (1982) considered the problem of dividing a given surplus between two players sequentially, and then proposed a model in which the two players alternately make and respond to each other's offers through time. He further characterized the perfect equilibrium outcomes, which depend on the players time preferences and order of moves. Using both equal and unequal bargaining cost conditions and an unlimited number of rounds, two experiments were designed to compare the perfect equilibrium model to alternative models based on norms of fairness. We report analyses of final agreements, first offers, and number of bargaining rounds, which provide limited support to the perfect equilibrium model, and then conclude by recommending a shift in focus from model testing to specification of the conditions favoring one model over another.  相似文献

Although survey researchers are often warned against using prestigenames in questions (e.g., identifying Contra aid as "PresidentReagan's policy"), prestige names are still commonly used. Tolearn more about the effects of using prestige names, we analyzetwo sets of experiments—on judicial confirmation electionsand on an initiative on tax indexing. The results indicate thatprestige names do more than shift responses in one direction—they eliminate the effect of education on DKs and provide moreof a political basis for the responses.  相似文献

A recent American survey of attitudes toward societal multiculturalism vs. assimilation has found surprisingly widespread support for maintaining heritage cultures not only among immigrant minority groups but also among most subsamples of majority host groups, black and white. Working-class whites are the one exception. This pilot study explores the same attitude domain in a contrasting European setting. Randomly selected samples of middle- and working-class families (a mother, father, and teenage son or daughter) from a small city in France were interviewed. As a group, they were neutral to slightly favorable to immigrants maintaining heritage cultures and languages rather than losing them through assimilation. On measures of attitudes toward specific immigrant groups, there were marked intergroup dyfferunces with Maghrebian Arabs rated leist favorably and Southeast Asians, the model immigrants, most favorably. Comparisons of subgroups of respondents who varied in terms of (a) political left-right orientation, (b) social class standing, (c) degree of religiosity, and (d) generational level provide the base for a more general discussion of cultural assimilation and multiculturalism.  相似文献

CONTEXT EFFECTS FOR CENSUS MEASURES OF RACE AND HISPANIC ORIGIN   总被引:1,自引:0,他引:1  
This paper reports on the results of a split-ballot experimentconducted in 1987 to test alternative versions of the decennialcensus long form. Two forms were randomly assigned and self-administeredin group sessions involving a total of 515 respondents. Theorder of race and Hispanic origin items was experimentally manipulated.The standard long form asks race, then Hispanic origin. Theexperimental form reversed the order of the items in order toreduce perceived redundancy, and to create a more restrictedframe of reference for the race item. The objectives of thecontext manipulation were (1) to reduce item nonresponse forthe Hispanic origin item, and (2) to reduce reporting of "Otherrace" by Hispanics in the race item. Objective (1) was met.Objective (2) was met for Hispanics born in a U.S. state, butnot for immigrants. The results are interpreted as reflectinga process of acculturation that affects how Hispanic respondentsapply U.S. racial categories "white" and "black" in the census.  相似文献

This paper seeks to explore triangular dimensions in individual psychotherapy. In addition to serving as the dyadic object of transference projection and/or as selfobject for a person in psychotherapy, the therapist may be called upon to help the patient work on relationships with certain early, important people or their representations and on the interplay between such relationships and the therapeutic one, that is, in a triangular configuration. Because patients' attempts to introduce others into individual psychotherapy are sometimes experienced by therapists as resistant rather than as integral to the therapeutic process, I propose an empathic reconsideration of such patient efforts to get us to help with the complicated dimensions of human relatedness.  相似文献

The following article is one of a series that deal with the provision of health care services around the world. Other countries in the series include Germany, Italy, Japan, Mexico, the Netherlands, and the United States. Countries scheduled for coverage in the series include Austria, France, Singapore, Spain, and the United Kingdom. The countries are described using a grid of characteristics so that comparisons may be made more easily. All of the analyses, along with further comparative data, will be gathered into a freestanding book to be published later in the year. Dr. Mendoza serves as editor for the project.  相似文献

Prior to the 1980s, managed care was virtually nonexistent as a force in health care. Presently, 64 percent of employees in America are covered by managed care plans, including health maintenance organizations (20 percent) and preferred provider organizations (44 percent). In contrast, only 29 percent of employees were enrolled in managed care plans in 1988 and only 47 percent in 1991. To date, the primary reason for this incredible growth in managed care has been economic-market pressure to reduce health care costs. For the foreseeable future, political pressures are likely to fuel this growth, as managed care is at the center of President Clinton's national health care plan. Although there are numerous legal issues surrounding managed care, this article focuses primarily on antitrust implications when forming managed care entities. In addition, the corporate practice of medicine doctrine, certain tax issues, and the fraud and abuse laws are discussed.  相似文献

The current economic climate has been particularly hard on non-profit and public human services organizations, frequently resulting in managing organizational decline. The authors believe that the dominant concern should be with fostering organizational growth. To this end, they suggest that nonprofit board members and executives, as well as public sector leaders, need to concern themselves with the concurrent management of two agendas: Running the Shop and Meeting the Change Challenge. This can be done effectively through the use of strategic issue management, which is a set of techniques that represents a blend of traditional strategic management and change management approaches.  相似文献
