This article describes mortality patterns for nonprofit organizations in a major U.S. metropolitan area between 1980 and 1988. Twenty percent of the nonprofits in a panel ceased operations during this period. Mortality rates were found to vary widely. In some instances, high mortality was found in parts of the sector that were growing rapidly. Overall, nonprofits that ceased to operate were younger and smaller, used fewer strategies to attract funders, and had less diversified income streams than survivors. These patterns also varied substantially. The results point to the drawbacks of using limited or commonsense information and the necessity of theory-based research. 相似文献

Immigration has long been a national and state concern. The 1989 Legalized Population Survey (LPS-1) collected data on illegal immigrants to the US who subsequently became legalized aliens under the provisions of the 1986 Immigration Reform and Control Act. These data are used in a study assessing whether undocumented male and female immigrants improve their earnings and occupational status over time and the extent of variation in occupational status and mobility by gender and region. The data indicate that both undocumented men and women, on average, improved their earnings and occupational status between their first jobs in the US and their jobs just before applying for legalization under the 1986 Immigration Reform and Control Act. However, the earnings, occupational status, and occupational mobility of men were greater than for women. 相似文献

The projected increase of people in Japan aged 75 years and older in the years to come implies the increase of the disabled elderly. Thus, the core of societal preparation for the aging of the population is generally considered to be the expansion of services for the disabled elderly. However, gerontological studies on the health status of the elderly conducted in Japan show that the prevalence of disability is quite low and even decreasing. Relative to the services for the disabled elderly, preventive services for the healthy elderly have long been overlooked. In 1994, the Metropolitan Tokyo Government organized a task force to develop a new health education program as the preventive health service for the healthy urban elderly. A preliminary plan outlining the health education program--consisting of propagation with a booklet, on-the-job training of practitioners, and development of new curricula and teaching materials--was proposed by the authors for discussion within the task force. Although the inquiry has just begun and the plan is still nascent, it seems adequate to fit the needs for preventive health services in the near future. 相似文献

This paper provides an overview of retirement patterns in Hong Kong on the basis of limited data. A censored regression model
is used to infer the retirement age from people‘s current retirement status and their current age. This model is equivalent
to a restricted probit model, and the interpretation of parameters is straightforward. The results clearly show a negative
income effect on the retirement decision. The retirement age seems to be positively related to lifetime earnings but negatively
related to the rate of decline of earnings with age.

This paper models household fertility decisions by using a generalized Poisson regression model. Since the fertility data
used in the paper exhibit under-dispersion, the generalized Poisson regression model has statistical advantages over both
standard Poisson and negative binomial regression models, and is suitable for analysis of count data that exhibit either over-dispersion
or under-dispersion. The model is estimated by the method of maximum likelihood. Approximate tests for the dispersion and
goodness-of-fit measures for comparing alternative models are discussed. Based on observations from the Panel Study of Income
Dynamics of 1989 interviewing year, the empirical results support the fertility hypothesis of Becker and Lewis (1973).
