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

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 author examines family structure in Santa Fe, the capital of New Granada, a Spanish colony that included Colombia, Ecuador, Panama, and Venezuela. The focus is on the late eighteenth and early nineteenth centuries. He finds that social class structure was closely related to ethnic group and skin color, and that the sex ratio was biased toward women. Women also headed nearly 50% of all households. Data are mainly from the 1801 smallpox census.  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

Contemporary immigration to the United States and the formation of new ethnic groups are the complex and unintended social consequences of the expansion of the nation to its post-World War II position of global hegemony. Immigrant communities in the United States today are related to a history of American military, political, economic, and cultural involvement and intervention in the sending countries, especially in Asia and the Caribbean Basin, and to the linkages that are formed in the process that open a variety of legal and illegal migration pathways. The 19.8 million foreign-born persons counted in the 1990 U.S. census formed the largest immigrant population in the world, though in relative terms, only 7.9% of the U.S. population was foreign-born, a lower proportion than earlier in this century. Today's immigrants are extraordinarily diverse, a reflection of polar-opposite types of migrations embedded in very different historical and structural contexts. Also, unlike the expanding economy that absorbed earlier flows from Europe, since the 1970s new immigrants have entered an hourglass economy with reduced opportunities for social mobility, particularly among the less educated, and new waves of refugees have entered a welfare state with expanded opportunities for public assistance. This paper seeks to make sense of the new diversity. A typology of contemporary immigrants is presented, and their patterns of settlement, their distinctive social and economic characteristics compared to major native-born racial-ethnic groups, and their different modes of incorporation in—and consequences for—American society are considered.  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

Common binary regression models such as logistic or probit regression have been extended to include parametric link transformation families. These binary regression models with parametric link are designed to avoid possible link misspecification and improve fit in some data sets. One and two parameter link families have been proposed in the literature (for a review see Stukel (1988)). However in real data examples published so far only one parameter link families have found to improve the fit significantly. This paper introduces a two parameter link family involving the modification of both tails of the link. An analysis based on computationally tractable Bayesian inference involving Monte Carlo sampling algorithms is presented extending earlier work of Czado (1992, 1993b). Finally, the usefulness of the two tailed link modification will be demonstrated in an example where single tail modification can be significantly improved upon by using a two tailed modification.  相似文献
