Employment has become increasingly precarious in developed countries, meaning that, for many young adults, jobs provide neither benefits nor security, more work is part time, and employers are increasingly hiring workers from temporary help agencies and contract companies rather than as employees of their own company. These changes in employment relations have profound effects on gender roles and on family transitions of young adults, especially young men and in particular in countries such as Japan, where there are rigid family norms and the male‐breadwinner tradition still prevails. The authors examined the effects of the experience of non‐regular work on the timing of marriage and whether this differs by sex. Using recent life history data from Japan, they found that men working in non‐regular jobs are especially likely to postpone marriage. The implications of the growth of precarious work for changes in work and family institutions in Japan are discussed. 相似文献

Women with few social resources are at elevated risk of partner abuse. Certain evidence suggests that African American and Hispanic women, who are overrepresented in the lower socioeconomic strata, are at particularly high risk. We compare women's risk of partner violence, defined as moderate and severe, among 2,400 low‐income African American, Hispanic, and non‐Hispanic Whites from “Welfare, Children and Families: A Three City Study” and find that these groups differ in their risk of degrees of violence. Specific nation‐of‐origin Hispanic subgroups also manifest important differences in their violence risk profiles. We argue that a better understanding of victimization requires more detailed ethnic categorization and a more refined understanding of the meaning of domestic violence for different groups. 相似文献

A joint latent class changepoint model to improve the prediction of time to graft failure 总被引:1,自引:0,他引:1
Francisca Galindo Garre Aeilko H. Zwinderman Ronald B. Geskus Yvo W. J. Sijpkens 《Journal of the Royal Statistical Society. Series A, (Statistics in Society)》2008,171(1):299-308
Summary. The reciprocal of serum creatinine concentration, RC, is often used as a biomarker to monitor renal function. It has been observed that RC trajectories remain relatively stable after transplantation until a certain moment, when an irreversible decrease in the RC levels occurs. This decreasing trend commonly precedes failure of a graft. Two subsets of individuals can be distinguished according to their RC trajectories: a subset of individuals having stable RC levels and a subset of individuals who present an irrevocable decrease in their RC levels. To describe such data, the paper proposes a joint latent class model for longitudinal and survival data with two latent classes. RC trajectories within latent class one are modelled by an intercept-only random-effects model and RC trajectories within latent class two are modelled by a segmented random changepoint model. A Bayesian approach is used to fit this joint model to data from patients who had their first kidney transplantation in the Leiden University Medical Center between 1983 and 2002. The resulting model describes the kidney transplantation data very well and provides better predictions of the time to failure than other joint and survival models. 相似文献

Using data from the 1980, 1985, and 1990 Current Population Surveys, we show that the link between early fertility and nonmarital births has become stronger. Women who give birth earlier are increasingly likely to be unmarried. In contrast, we find a weaker association between first births at young (versus older) ages and (1) a rapid pace of subsequent childbearing and (2) higher completed fertility. We discuss possible causes and consequences of these changes. 相似文献

The price of a university education has increased over the years. As a result, students often graduate with thousands of dollars of debt. Conducting research or developing class projects that require personal expenditures can be overwhelming, if not impossible. Participation in research and in developing projects can enhance a student's educational experience. In an effort to address cost issues and provide an optimal learning experience for all students through participation in projects and research, the College of Health Sciences at the University of Texas at El Paso (UTEP) collaborated with a regional foundation to fund health-oriented students' projects and research. Approximately 100 projects have been funded in amounts from 200 dollars to 10,000 dollars at UTEP. Similar programs can be replicated at other US universities. Establishing a general fund and identifying contributors may be a viable option, although finding a foundation or agency to fund the project poses a challenge. 相似文献

The objective of this study is to examine the influences of gender on long-term care service use among older Mexican American widows and widowers. Our analysis is based on a sample of 773 widows and 183 widowers from the Longitudinal Study of Elderly Mexican American Health (H-EPESE). In this sample widows resemble widowers in terms of demographic and health characteristics. However, widows report more financial strain than widowers and a greater welfare dependency (SSI) and Medicaid use. Among those who suffered diminished health, widows were more likely than widowers to use community-based long-term care services whereas widowers were more likely to enter a nursing home. Widows also had more instrumental and socioemotional support than widowers. Serious cognitive and functional impairment, though, places widows and widowers at the same risk of institutionalization. We end with a discussion of the policy implications of these findings. 相似文献

In this paper we examine the associations among perceived financial strain and various health measures--including self-rated health, self-reported functional capacity, performance-based mobility, and mortality--in a sample of older Mexican-origin individuals. We employ the Hispanic Established Population for Epidemiological Studies of the Elderly, an eight-year longitudinal survey of over 3,000 Mexican-origin individuals in five southwestern states who were initially interviewed in 1993 and 1994. Although financial strain is associated with actual income and poverty, it is also associated with cognitive capacity, depression, and self-esteem, and while it is strongly associated with subjective measures, it has a weaker association with more objective measures, such as performance-based mobility and mortality. Financial strain appears to be part of a package of cognitions and emotions indicative of low morale or demoralization that has adverse effects on subjective health. 相似文献
