In this article, we review what has been learned to date from the first 5 years of the Fragile Families and Child Wellbeing study about child support, fatherhood, and marriage. The article first describes the parents' circumstances at the time of the child's birth, then examines the trajectories of parents' relationships (with each other and others), fathers' financial contributions and other indicators of fathers' involvement with their children 5 years later; and finally reviews what has been learned about the effect of child support enforcement on these three aspects of families' lives. We find that most unmarried parents are either cohabiting or romantically involved at the time of the child's birth, but are a distinctly disadvantaged group as compared with married parents. Five years later, most of these parents are no longer romantically involved, however, most of the fathers are still seeing their children on a regular basis, and about half are contributing either formally or informally to their support. Strong child support enforcement appears to increase formal and decrease informal support from fathers, reduce marriage among parents, and have a weak positive effect on father involvement. More research is necessary to understand whether these findings are robust over time and across samples of unmarried parents.  相似文献

Parents Beyond Borders, a curriculum first implemented in 2008 as part of The Center for Family Life's ParentShip Program, encourages group members to create a shared narrative about their traumatic immigration experiences. The result is twofold. First, immigrant parents gain a more assertive and poignant voice to communicate with family and others in their lives when sharing their family's acculturation experience. Second, because social group work promotes recognition of collective trauma due to the community's experience of marginalization, it improves members' group self-concept and empowers them to take action and advocate for themselves.  相似文献

Abstract

The affective relationships of young adult females and their fathers were investigated for effects on dating relationships, dating anxiety, and interpersonal trust. Ninety-six college females, 66 with married parents and 25 with divorced parents, completed questionnaires about father-daughter intimacy, dating satisfaction, dating anxiety, and; trust. It was hypothesized that females with divorced vs. married parents, and females scoring lower on the intimacy scale, regardless of family structure, would experience less father-daughter intimacy, lower dating satisfaction and trust, and higher dating anxiety. Multivariate analysis of variance showed that females with divorced vs. married parents experienced significantly less intimacy with their fathers but similar levels of trust, anxiety, and satisfaction. Comparisons of females high and low in father-daughter intimacy showed no differences in trust, anxiety, or dating satisfaction. The relative importance of parents' marital status versus other factors relevant to divorce (e.g., intimacy, presence of a stepfather) will be discussed.  相似文献

In this second of two papers based on a study of payment issues within foster care, the focus is on expenditure. It is argued that the hybrid public/private nature of fostering gives rise to contradictory pressures for carers, including the status of maintenance payments as both part of family budgets and a form of delegated public expenditure. For example, carers are required in principle both to spend fixed amounts upon foster children and to treat them in like fashion to their own children. In this paper, the issue of ‘like treatment’ is explored, along with the significance of payment for ‘children who foster’ and for relationships between carers and foster children. Also examined are the challenges presented by differences between carers’ material circumstances and those of birth families, especially when reunification is planned. Overall, the paper seeks to show how the handling of expenditure becomes closely entwined with inter‐personal dynamics within foster care.  相似文献

The magnitude of racial differences in first birth timing vary greatly depending upon the data sources from which they are estimated. Vital registration data (Heuser 1976; with updates from the National Center for Health Statistics 1974–1990) show that in recent years nonwhites have higher risks of a first birth at virtually all ages compared to whites. As a result very large and historically novel differentials in childlessness are forecast using these data (see Rindfuss et al. 1988; Chen & Morgan 1991; Morgan & Chen 1992). However, retrospective fertility history data collected from the 1980, 1985 and 1990 Current Population Surveys (CPS) suggest much smaller racial differences in completed childlessness and isolate racial differences in probabilities of first births at young ages. Differences also exist between theses two series for whites prior to the mid-1960s but not afterwards. Reasons for these differing estimates are suggested and examined. We conclude that a substantial portion of the differences result from an accumulation of biases in the vital registration estimates that affect primarily estimates of first birth timing. Thus, the CPS data provide a more firm basis for racial comparisons of first birth timing.  相似文献

We study sojourn times of customers in a processor sharing queue with a service rate that varies over time, depending on the number of customers and on the state of a random environment. An explicit expression is derived for the Laplace–Stieltjes transform of the sojourn time conditional on the state upon arrival and the amount of work brought into the system. Particular attention is paid to the conditional mean sojourn time of a customer as a function of his required amount of work, and we establish the existence of an asymptote as the amount of work tends to infinity. The method of random time change is then extended to include the possibility of a varying service rate. By means of this method, we explain the well-established proportionality between the conditional mean sojourn time and required amount of work in processor sharing queues without random environment. Based on numerical experiments, we propose an approximation for the conditional mean sojourn time. Although first presented for exponentially distributed service requirements, the analysis is shown to extend to phase-type services. The service discipline of discriminatory processor sharing is also shown to fall within the framework.  相似文献

黔东南州作为西部欠发达省份的民族自治地区,出生性别比长期、普遍、高度的失衡已经对经济发展、社会安定造成一定影响。虽然出生性别比失衡问题得到政府和社会的广泛关注和重视,并自2004年起开展了系列治理活动,但出生性别比升高的势头并未因之而有所遏制。本文希望通过对出生性别比失衡人口规模的计算,以及预测失衡导致该州未来男女人口规模和适龄结婚人口规模差异,使人们对失衡状况与未来影响有更清晰的认识,并为进一步治理提供参考素材。  相似文献
