Using the 1994–1998 waves of the Current Population Survey—Child Support Supplement (N =5,387), the aims of this study are to document child support obligation rates of nonresident fathers, to examine the effect of the obligation rate on child support compliance, and to calculate the trade‐off between fathers’ financial responsibility and children's well‐being, paying particular attention to low‐income fathers. The results indicate that low‐income fathers have high child support obligation rates, which significantly reduce their child support compliance. Although lowering the obligation rate for these fathers may improve their compliance, it does not fully offset the lowered obligation amounts and leads to a 30% net payment loss for welfare mothers and a 43% loss for nonwelfare mothers. Policy implications are discussed. 相似文献

The environmental crisis is presented as a contested cultural discourse with conflicting social and political narratives pervasively targeted at children. Textual analysis of an environmental cartoon, and interviews with the cartoon's producers and child viewers, are used to deconstruct popular themes being transmitted to children in the name of "saving the planet". The cartoon is critiqued as representing and promoting a liberal environmental paradox espousing: a simultaneous call for children to both conserve and consume; a diffusion of responsibility that supports the notion of environmental crisis as everybody's fault; simplistic, individualistic solutions to complex corporate and bureaucratic problems. Narratives of nature as a social actor are proposed as rhetorical and epistemological alternatives for the recreation of children's social, political, and environmental awareness. 相似文献

This paper reexamines the predictability of stock returns with a nonparametric model. We first identify, through a set of diagnostic tests, five lagged predictive factors from a linear model. Using these factors, we predict one-month-ahead stock index returns with a nonparametric approach. We find that our nonparametricmodel. We first identify, through a set of diagnostic tests, five lagged predictive factors from a linear model. Using these factors, we predict on -month-ahead stock index returns with a nonparametric approach. We find that our nonparametric model can correctly predict about 74% of stock index return signs. With various ex ante trading rules based on nonparametric predictions and transaction cost schedules, we then compare the performance of "managed" portfolios with that of the buy and hold portfolios. We fmd that the managed portfolios are mean-variance dominant over the buy-and-hold strategies when no or low transaction costs are assumed. When high transaction costs are assumed instead, the mean-variance dominance diminishes However,the Sharpe index of risk-adjusted portfolio performanceindicates that the managed portfolios significantly outperform the buy-and-hold strategies even for the high-transaction cost scenario. We show that the difference in performance between the managed portfolios and the buy-and-hold strategies can be partially explained by the January effect or the small firm effect. In sum, this paper demonstrates the merits of using a nonparametric approach for predicting stock returns and testing market efficiency. 相似文献

The thesis of this article is that sufficient and convincing research evidence has accumulated to indicate that a sixth stage of career development—career renewal—occurs for many people between the end of the establishment stage and the beginning of the maintenance stage. This article explains why a renewal stage was overlooked in the 1940s and 1950s, clarifies the meaning of renewal as it applies to career development, compares the transitions of men and women in their early 40s, and offers suggestions for the counseling of clients who are dealing with the task of career renewal. 相似文献

In Korea, family policy as a public policy gained interest in the 1980s, when the Ministry of Health and Social Affairs (since January 1995 the Ministry of Health and Welfare) renamed the Maternal and Child Bureau the Family Welfare Bureau. This paper first presents a brief overview of the traditional family system and values in Korea and examines changes in economic and social indicators, changes in family functions and roles, and changes in attitudes toward family that have occurred following industrialization and urbanization. The paper then briefly explains some of the problems Korean families face today. It next examines the Family Planning Program and its results. Finally, it turns to an examination and critique of the policies and programs administered by the Family Welfare Bureau.Yeonoak Baik is a Family Advocacy Therapist for the 8th U.S. Army c/o Commander, 43rd Surgical Hospital (MA), ATTN: EAMC-SH-FAP, Room D-108, Unit #15190, APO AP, 96271-0126.

We investigated the sensitivity of measures of cognitive ability and socioemotional development to changes in parents' marital status using data from the National Longitudinal Survey of Youth, 1979. We used several scores for each assessment, taken at different times relative to parents' marital transitions, which allowed us to trace the effects starting up to five years before a parent's change in marital status and continuing for up to six years afterward. It also allowed us to correct for the unobserved heterogeneity of the transition and nontransition samples by controlling for the child's fixed effect in estimating the time path of his or her response to the transition. We found that children from families with both biological parents scored significantly better on the BPI and the PIAT-math and PIAT-reading assessments than did children from nonintact families. However, much of the difference disappeared when we controlled for background variables. Furthermore, when we controlled for child fixed effects, we did not find significant longitudinal variation in these scores over long periods that encompass the marital transition. This finding suggests that most of the variation is due to cross-sectional differences and is not a result of marital transitions per se. 相似文献

We consider the scheduling of truck arrivals at an air cargo terminal. By coordinating arrivals of cargo delivery trucks with outbound flight departure schedules, some of the shipments can be transferred directly to the departing flights, while others will be stored at the terminal's storage facility and incur extra handling and storage costs. The objective is to obtain a feasible schedule so as to minimize the total cost of operations. We formulate the problem as a time‐indexed integer program and show that, even with limited number of unloading docks at the terminal, the problem is non‐trivial (NP‐hard in the strong sense). Our solution method includes an exact solution procedure to determine an optimal unloading sequence for the shipments carried by each truck, together with a Lagrangian relaxation‐based heuristic for assigning trucks to truck docks and determining truck arrival times. We conducted computational experiments to test the performance of our solution method. Computational results show that our method can generate near‐optimal solutions efficiently. Our simulation results indicate that the scheduling approach proposed in this paper has the potential to generate significant cost savings over a first‐come, first‐served approach currently used at the air cargo terminal that we observed. 相似文献

This paper describes the first post-Master's program in the US in end-of-life care for social workers. Developed at the Smith College School for Social Work, this program used innovative relational methods in student recruitment, curricular design, supervision, and leadership development, based upon input from the faculty, students, and field supervisors. Collaborations emerged with funders, agencies, and programs nationally. The program was based on a pedagogical stance that clinical work with dying people requires the capacity to be fully present- in individual, group, and family work; in interdisciplinary meetings; and in advocating for quality and equity of care-while attending to diverse and at-risk populations. Students deepened their clinical skills and took leadership in the field of end-of-life care. 相似文献
