Previous research has neither fully examined family structure across the life course nor considered increasing variation in family types. Using data from the National Longitudinal Study of Adolescent Health (N = 11,318), I examine the influence of longitudinal measures across childhood of family structure duration and the number and timing of parent transitions (entrances and exits) on indicators of grade point average (GPA), college expectations, and suspension or expulsion in adolescence. I also examine whether parent gender moderates these effects. Results show that mother transitions during early childhood affect all outcomes, whereas time in mother‐absent families influences GPA and school discipline. I find evidence for parent gender differences in transition effects; mother transitions, especially early ones, have more severe consequences than father transitions.  相似文献

This study investigated the internal validity of the Index of Spouse Abuse (ISA) (Hudson & McIntosh, 1981) in a sample of 583 African American women who sought health care at a tertiary care hospital in Atlanta, Georgia. Three models were tested with confirmatory factor techniques: (a) Hudson and McIntosh's original Index of Spouse Abuse two factor model; (b) Campbell, Campbell, Parker, and Ryan's three factor model (Campbell, Campbell, King, Parker, & Ryan, 1994); and (c) an alternative model of physical and nonphysical abuse. This alternative model is based in part on Tolman's conceptualization of psychological abuse as a construct comprised of two related but distinct factors: controlling and emotionally abusive behaviors (Tolman, 1999). Results show that the alternative model fits the data better than the first two models. Findings support the continued use of the ISA, but with proposed modifications.  相似文献

Parents seeking to balance their work lives with family responsibilities often find the challenge made more difficult by outdated images of the ideal worker, the good mother, and the good father. Social and legal constraints on mothers' choices exacerbate the problem. While other countries have implemented national work/family policies, the climate in the United States seems unreceptive to federal government mandates for meaningful changes in employees' work hours, schedules, and paid leave, or for sweeping new child care subsidies. As a viable interim measure, we propose a statute forbidding discrimination based on family responsibilities, which would tap deeply-felt values about the importance of family caregiving, serve as an important symbolic statement, and be useful to courts.  相似文献

Findings from children and youth who participated in structured after-school interventions in four urban public housing communities are used to illustrate the complexities of conducting program-based research in after-school settings. Findings from four field investigations reveal the importance of family support, reading skills, parent involvement, and positive peers in engaging youth in services, developing academic skills and avoiding involvement in problem behavior. Challenges in conducting program-based research and lessons learned from each of the four studies are discussed in the context of social work practice and after-school programming for at-risk children and youth.  相似文献

In this article, we undertake an event-history analysis of fertility in Ghana. We exploit detailed life history calendar data to conduct a more refined and definitive analysis of the relationship among personal traits, urban residence, and fertility. Although urbanization is generally associated with lower fertility in developing countries, inferences in most studies have been hampered by a lack of information about the timing of residence in relationship to childbearing. We find that the effect of urbanization itself is strong, evident, and complex, and persists after we control for the effects of age, cohort, union status, and education. Our discrete-time event-history analysis shows that urban women exhibit fertility rates that are, on average, 11% lower than those of rural women, but the effects vary by parity. Differences in urban population traits would augment the effects of urban adaptation itself. Extensions of the analysis point to the operation of a selection effect in rural-to-urban mobility but provide limited evidence for disruption effects. The possibility of further selection of urbanward migrants on unmeasured traits remains. The analysis also demonstrates the utility of an annual life history calendar for collecting such data in the field.  相似文献

Residential development in urban and suburban settings is a major cause of habitat change affecting avian communities. The effects from land-clearing prior to initiation of construction followed by landscaping focused on traditional aesthetics has reduced habitat diversity at multiple levels. These residential developments generally emphasize the use of ornamental, nonindigenous vegetation with little to no concern for native species and natural vegetation parameters. As a result, avian community composition and diversity is changed. We compared avian communities at three sites in Bexar County, Texas; two residential neighborhoods in the city of San Antonio and an unincorporated undeveloped site, Government Canyon State Natural Area. The residential neighborhoods were a Texas Parks and Wildlife Department certified wildscapes development and a traditionally developed neighborhood. Bird abundance and species richness in the neighborhoods were greater than at Government Canyon State Natural Area (P < 0.01), but no differences existed between the neighborhoods. Bird diversity was greatest at the wildscapes neighborhood (P < 0.01). Further, bird diversity did not differ between the traditional neighborhood and the natural area. Evenness differed among sites (P = 0.006) with the natural area having the greatest value. Bird diversity measures correlated with woody plant density and vertical cover (r = 0.358 to 0.673, P < 0.05) at residential sites. Residential areas incorporating natural landscapes into their design attracted a greater variety of birds than traditionally landscaped residential areas.  相似文献

1. Described as one of the "pains of imprisonment," separation may be particularly difficult for women in prison because most functioned in multiple relational roles, including mother, wife, girlfriend, daughter, sister, and friend, before incarceration. 2. In the absence of consistent contact with family, friends, and other loved ones outside prison, incarcerated women may seek to develop connections with other inmates as a way to adapt to life in prison. 3. Positive adaptation may allow incarcerated women to take advantage of educational/vocational, parenting, and drug treatment programs offered in prison, thus facilitating their adaptation after release.  相似文献

This study explores the relationship between residential, biological fathers' parental engagement, financial contributions, and psychological well‐being in 2‐parent families. Specifically, this study focuses on how fathers' parental engagement and financial contributions are related to their self‐esteem, self‐efficacy, and psychological distress. Analyses utilize data from the first 2 waves of the Panel Study of Income Dynamics' Child Development Supplement and employ a subsample of father‐child pairs (N = 771). The most consistent finding was that fathers' engagement in parenting and financial contributions to the family predicted improvements in fathers' psychological well‐being. On the other hand, the results found very limited support for the more common proposition that healthy psychological functioning promotes increases in fathers' parental engagement and financial contributions.  相似文献

This study was conducted to determine the level of testicular self-examination (TSE) awareness and practice and to identify characteristics related to TSE awareness and practice in a sample of college men. A 26-item survey was administered to 404 male college students. Forty-two percent reported they were aware of TSE, more than 41% had been taught TSE, and 22% had examined their testicles at least once in their lifetime. Approximately 8% of the study population reported practicing TSE once a month. The PRECEDE model was used to categorize the significant variables that influenced monthly TSE practice. Age and college class were significant demographic variables; predisposing factors included having heard of testicular cancer, knowing about recommended practice rates, feeling that cancer can be controlled, and awareness of the risk factors associated with testicular cancer. Having been taught TSE was the statistically significant enabling factor. A discussion of TSE in the past 6 months was the significant reinforcing factor.  相似文献
