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

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

Last year, the Internal Revenue Service (IRS) issued Revenue Procedure 93-19 (Rev. Proc. 93-19), which provides guidelines regarding service and other contracts involving facilities financed with tax-exempt bonds. Rev. Proc. 93-19 creates four "safe harbors" for certain contracts signed by tax-exempt organizations that will not jeopardize the organizations' tax-exempt bond interest. Those guidelines and methods for complying with them are the subject of the following article. "Health Law" is a regular feature of Physician Executive contributed by Epstein Becker & Green. Mark Lutes of the law firm's Washington, D.C., offices serves as editor of the column.  相似文献

A survey was mailed to 100 physician executives identified through the 1991 American College of Physicians Executives directory. The subjects were asked to rate 17 managerial areas on their value to the subjects' current work, on the subjects' preparation in the areas, and on the need for training in the areas. In addition, the subjects were asked how best to accomplish training in the areas and for a list of areas of greatest importance in the future for physician executives. The subjects rated communication skills, quality assurance, utilization review, and personnel management as being of primary value in their current roles. Preparation was most adequate in communication skills and most inadequate in the areas of finance and organizational management. Training was deemed desirable in all areas, but was thought to be most necessary in communication skills, negotiations, strategic planning, and organizational management. There was least desire for training in the areas of labor law and employment law. The most popular means of training were doing a fellowship in administrative medicine, receiving continuing education through seminars or workshops, or getting a degree in management.  相似文献
