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

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

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

Nikrowa is a riverine village located in Ovia North-East Local Government Area of Edo State. This paper examines the relationship between the environment and the health status of women and children in the village. Data used in this essay were obtained mainly in focus groups from a study of women and health service utilization in Nikrowa. Women in Nikrowa farm, fish, collect water and firewood, and process and prepare food. They also bear many children. Their hard physical labor causes them to suffer continuous body aches and pains. Environment-related illnesses such as malaria, measles, dysentery, and diarrhea are prevalent among children. The geographical isolation of Nikrowa limits access to modern health care facilities, so traditional therapies are used to treat prevailing illnesses. It is suggested that women have access to fertilizers in order to improve soil fertility and agricultural yields. Fuelwood and adequate and safe water supplies should be made readily available to women. Moreover, access roads to rural areas should be improved to facilitate transport to modern health care facilities, and rural primary health care facilities should be helped to provide efficient services by providing trained staff and ensuring regular supplies of drugs.  相似文献

"This article examines the probable effects of the North American Free Trade Agreement (NAFTA) on migration from Mexico to the United States, disputing the view that expansion of jobs in Mexico could rapidly reduce undocumented migration. To the extent that NAFTA causes Mexican export agriculture to expand, migration to the United States will increase rather than decrease in the short run. Data collected in both California and the Mexican State of Baja California show that indigenous migrants from southern Mexico typically first undertake internal migration, which lowers the costs and risks of U.S. migration. Two features of employment in export agriculture were found to be specially significant in lowering the costs of U.S. migration: first, working in export agriculture exposes migrants to more diverse social networks and information about U.S. migration; second, agro-export employment in northern Mexico provides stable employment, albeit low-wage employment, for some members of the family close to the border (especially women and children) while allowing other members of the family to assume the risks of U.S. migration."  相似文献
