This study examines how the neighborhood environments experienced over multiple generations of a family influence children's cognitive ability. Building on recent research showing strong continuity in neighborhood environments across generations of family members, the authors argue for a revised perspective on "neighborhood effects" that considers the ways in which the neighborhood environment in one generation may have a lingering impact on the next generation. To analyze multigenerational effects, the authors use newly developed methods designed to estimate unbiased treatment effects when treatments and confounders vary over time. The results confirm a powerful link between neighborhoods and cognitive ability that extends across generations. A family's exposure to neighborhood poverty across two consecutive generations reduces child cognitive ability by more than half a standard deviation. A formal sensitivity analysis suggests that results are robust to unobserved selection bias.  相似文献

This article compares divorce risks according to marriage type. The common dichotomy between ethnic homogamous and ethnic heterogamous marriages is further elaborated by differentiating a third marriage type; ethnic homogamous marriages between individuals from an ethnic minority group and a partner from the country of origin. Based on the analysis of data concerning the Turkish and Moroccan minorities in Belgium, it has been confirmed that the divorce risk associated with these marriages is higher than that of other ethnic homogamous marriages. However, specific divorce patterns according to marriage type also indicate the importance of differences between the minority groups.  相似文献

The purpose of this study was to examine Child Protection System (CPS) practice with children with developmental disabilities. This study used an emergent design, ethnographic interviews, purposive sampling, inductive data analysis, and grounded theory building. Ethnographic interviews were conducted with foster families, administrators, intake screeners, special investigators, and workers in one local CPS office. Participants expressed concern about the ability to identify disabilities, placement options, services to meet complex needs of children with disabilities, training and support for families, collaborative arrangements with other agencies, and disability training for CPS workers. Findings suggest strategies for improving CPS practice for children with developmental disabilities.  相似文献

The success of many knowledge‐intensive industries depends on creative projects that lie at the heart of their logic of production. The temporality of such projects, however, is an issue that is insufficiently understood. To address this, we study the perceived time frame of teams that work on creative projects and its effects on project dynamics. An experiment with 267 managers assigned to creative project teams with varying time frames demonstrates that, compared to creative project teams with a relatively longer time frame, project teams with a shorter time frame focus more on the immediate present, are less immersed in their task and utilize a more heuristic mode of information processing. Furthermore, we find that time frame moderates the negative effect of team conflict on team cohesion. These results are consistent with our theory that the temporary nature of creative projects shapes different time frames among project participants, and that it is this time frame that is an important predictor of task and team processes.  相似文献

Impaired functional status is associated with risk of elder mistreatment. Screening for functional impairment in elderly patients admitted to emergency departments could be performed to identify patients at risk for elder mistreatment who might benefit from further evaluation. This study utilized a modified Identification of Seniors at Risk (ISAR) screening tool to identify the proportion of elderly at risk for mistreatment due to functional difficulties presenting to two emergency departments in southeastern Virginia, one urban, the other rural. Of a 180-patient cohort (90 per site), 82 screened positive (46%), ISAR > 2 (range 0–6), indicating nearly half of all patients enrolled are at risk for mistreatment. Patients presenting to the urban emergency departments were potentially more at risk than their rural counterparts (p < 0.01). Health care professionals, particularly in urban settings, should consider screening seniors with a simple tool to identify patients at risk of elder mistreatment.  相似文献

In the initial analysis of data from a random sample of all those charged with child sexual abuse in Idaho over a 13-year period, only one predictive variable was found that related to recidivism of those convicted. Variables such as ethnicity, relationship, gender, and age differences did not show a significant or even large association with recidivism. The only variable that seemed to show both a significant and almost moderate association to recidivism was the Risk Assessment in the Sex Offender Evaluation reoffense. Comparisons were made to prior research as well as a discussion of implications of the sex offender evaluation for the legal process. Finally, a call for the continued need for further research is discussed.  相似文献

Abstract

This paper uses data from the Current Population Survey and administrative data from New York to simulate the poverty impact of the recent federal and state welfare reforms. We find that the federal welfare reforms would in the absence of additional state or local aid raise the poverty rate of families with children and the poverty gap (the amount needed to raise poor families’ incomes up to the poverty line). Although New York state and local welfare programs will offset much of this impact, we find that even with state and local aid, 16,000 families with children will move into poverty and 63,000 families with children, most of them already poor, will move into severe poverty, while the aggregate poverty gap will increase by nearly 25%.  相似文献
