CONTEXT EFFECTS FOR CENSUS MEASURES OF RACE AND HISPANIC ORIGIN 总被引:1,自引:0,他引:1
MARTIN ELIZABETH; DEMAIO THERESA J.; CAMPANELLI PAMELA C. 《Public opinion quarterly》1990,54(4):551-566
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

How our current system works and what changes need to be made are the subjects of intense scrutiny by policy makers today. One of the primary areas of concern with our present health care system is its accessibility to the average American, in terms of both price and ability to obtain insurance. With an estimated 37 million Americans without health care insurance, and countless others severely underinsured, this issue will lie at the core of any health care reform that results from the current debate. One possible approach to the uninsured problem that might alleviate the situation is community rating. 相似文献

Several countries have attempted to change human fertility through economic incentives. This paper presents simple mathematical models of the participation of couples in a locally funded program of economic incentives. The models take as a springboard China's one-child program. Localities with low per capita incentives attract few couples to the program, while localities with high incentives attract many couples at first, but the value of the benefits is then watered down. The models show that participation in the program may persistently oscillate or may decay to a stationary level. Which behavior occurs is determined by whether there are decreasing, constant, or increasing returns in the rates of participation in response to successive equal increments in the incentive offered, and by the extent to which prospective parents learn from experience with past oscillations in the incentives. The models raise many empirical questions about the dynamics of incentive programs. 相似文献

A cancer patient learning to walk again finds that his relationships with his two physical therapists affect his recovery. One woman gives hope as well as instruction. He advises healers to meet their patients as equals, "to take down as many barriers as they can, give away as many distancing privileges as possible." 相似文献

This article analyzes a 1989 Louis Harris and Associates survey designed to elicit information on the employment histories and job-stopping behavior of men and women who then were approaching or had recently reached retirement age. The results indicate that retirement often occurs gradually and includes a substantial period of "bridge employment." Most bridge jobholders work full-time, by choice, and report high levels of job enjoyment. Occupational mobility occurring late in life typically involves upward movement, although the pattern of change is quite different when it takes place outside, rather than within, the longest job. The principal concern identified in this article is the limited ability of some groups of workers (nonwhites, females, the less educated, and those in poorly compensated occupations) to either retain longest jobs or to obtain acceptable bridge employment. Health problems also frequently lead to early departures from the labor force. 相似文献

The success of the third sector depends on public confidence, and that confidence rests, in part, on holding managers, directors, and officers of nonprofits responsible for their conduct. This accountability can be accomplished by clearly defining the roles of these individuals and the stands that they are to uphold, and by providing channels for all interested to challenge uncontrolled activities. Though interest in this goal is unanimous, a debate exists over how to ensure oversight and accountability. 相似文献

Changes occurring in health care demand that physicians expand their professional knowledge and skills beyond the medical and behavioral sciences. Subjects absent from traditional medical education curricula, such as the economics and politics of health care, practice management, and leadership of professional organizations, will become important competencies, particularly for physicians who serve in management roles. Because physicians occupy a central role in planning and allocating medical care services and other health care resources, they must be better prepared to work with other health care professionals to create a new civilization, even if this means leaving the cloistered domain of "physician land" to serve as interface professionals between the delivery of medical services and the management of health care. Our research findings and conclusions strongly suggest that economic, management, and leadership competencies need to be incorporated into the professional development of physicians, especially in postgraduate and continuing education curricula. 相似文献

Social movement research has often been divided between organizational and cultural analyses of collective action. Organizationally oriented theorists have viewed indigenous organizational structure as the critical variable in the emergence of collective action. Political culture and cultural frame theorists have focused instead on the cultural frames that resonate with audiences, mobilizing them to action. But social movements cannot be the result of one or the other of these factors. An analysis of the 1989 Chinese movement illuminates the multivariate aspects of this social movement. This movement was a two-tiered movement with an organized student leadership tier and a mass audience. Enmeshed in university organizations and student networks, the student leaders relied on an organizational structure that had been emerging since the mid-1980s. This organized leadership tier employed cultural symbols and acts to mobilize mass audiences that were beyond the scope of the students' organizational linkages. The political theater of the organized student leaders was complemented by institutional changes that had been occurring over the decade of reform in China and a political opportunity that allowed wide coverage of the students' activities. 相似文献
