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

Using data from the 1976 and 1988 censuses, the author notes that the population of Senegal has grown by 37.6 percent over the period and that this growth is concentrated in urban areas. One feature of this trend has been the growing primacy of the capital Dakar and a decline in the relative importance of smaller towns. The need to discourage rural-urban migration by promoting socioeconomic development in rural areas is stressed. (SUMMARY IN ENG)  相似文献

Originally presented to the Society of Home Health Care Management of the American College of Physician Executives at its November 16, 1993, meeting in Tucson, Ariz., the program described in this article was the winner of the College's 1994 Innovations Award in Medical Quality Management, sponsored by Merck Sharp & Dohme. The program shows the potential of case management for both improvement in the quality of care and containment of costs for a managed care population with a substantial Medicaid segment. This article is part of a continuing series on innovative programs in home health care.  相似文献

The process of billing an insurance company for health care services has changed radically. In the past few years, the emphasis has been on automation. The change is fueled by the opinion of cost containment experts who claim that automation will help reduce costs in the U.S. health care delivery system. Key to success for the provider in adapting to this change will be understanding the coding used in the billing process and following standards of accuracy and fairness. This article is not intended to represent the adjudication rules of any particular insurance company. It is the result of experience as a practicing surgeon and as a consultant in the health care field.  相似文献

U.S. Department of Defense experience with internal partnership programs has indicated that a lack of close supervision by medical treatment facilities can result in cost increases. The use of medical practice guidelines or standards is the subject of active investigation. The global guidelines tend to be too rigid or too vague to affect the provision of care. Their general acceptance can often be low. The use of clinical guidelines, with supervision by a clinic peer, has been determined to be a provider-friendly method of delivering cost-effective, high-quality care. Comparisons were made between the supervised partners against the total expenditures for ENT outpatient CHAMPUS care. The results indicated not only a savings but a reduction in the rate of cost increases by more than 250 percent. It is our feeling that specialty provider, peer-directed medical standards can be applied in a cost-effective manner. Their adoption as an organization-wide standard for referral can be an important tool in maintaining quality while containing costs.  相似文献
