Ruhm CJ 《Journal of aging & social policy》1994,6(4):73-99
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

C. Czado 《Statistical Papers》1994,35(1):189-201
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

Reaves CF 《Physician executive》1994,20(3):32-34
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

"The prospects for today's second generation will be considerably shaped by their current social, economic and demographic status. This article provides a statistical portrait of children of immigrants by analyzing data from the 1990 U.S. Census of Population and Housing. With the second generation defined as children under age 18 with at least one foreign-born parent, the study describes place of residence; household demographic, social and economic circumstances; household head's socioeconomic status; and characteristics of children themselves. Data on second-generation children are broken down by year of immigration of parents and child's nativity. Data for children with native-born parents are provided for comparison." 相似文献

"This paper focuses on the effects of age at marriage and the sex-ratio on patterns of ethnic homogamy among Israeli women. We hypothesize that later marriages are more likely than early marriages to be heterogamous as the 'marriage market' shifts from school to the work-place. By the same token, when facing severe marriage squeezes women will be forced to out-marry. Employing data from the 1983 census, we model mate selection of women from Afro-Asian and Euro-American origin in various birth-cohorts. The results do not fully support our hypotheses: we find that in and of itself, age at marriage does not enhance ethnic heterogamy." 相似文献

"The purpose of this paper...is twofold: first, to specify a way of calculating place utility so that potential migrants could move to the place where overall place utility is maximized; and second, which is more important, to reveal how decision-makers in the real world, who are acting within 'bounded rationalities'...,make their decisions on where to migrate. This study is supported by an empirical survey of recent Chinese immigrants to Edmonton [Canada].... The findings reveal that when people evaluate different places, they do not necessarily look for the one that generates the highest overall value or utility across all properties.... The study further indicates that the assumption underlying most microeconomic models (that maximizing utility or benefit is the ultimate rule for choosing one location out of several) has not been verified."
