A vast amount of literature has documented negative associations between family instability and child development, with the largest associations being in the socioemotional (behavioral) domain. Yet, prior work has paid limited attention to differentiating the role of the number, types, and sequencing of family transitions that children experience, as well as to understanding potential heterogeneity in these associations by family structure at birth. We use data from the Fragile Families and Child Wellbeing Study and hierarchical linear models to examine associations of family structure states and transitions with children’s socioemotional development during the first nine years of life. We pay close attention to the type and number of family structure transitions experienced and examine whether associations differ depending on family structure at birth. For children born to cohabiting or noncoresident parents, we find little evidence that subsequent family structure experiences are associated with socioemotional development. For children born to married parents, we find associations between family instability and poorer socioemotional development. However, this largely reflects the influence of parental breakup; we find little evidence that socioemotional trajectories differ for children with various family structure experiences subsequent to their parents’ breakup. 相似文献

The primary objective of this study was to explore how middle-aged gay men in recovery cope with stigma and family relationships. For gay men, perceptions of acceptance of their sexual orientation and degree of social connectedness can play a role in their recovery from alcohol and substance use disorders. Yet gay men may have a more difficult time accessing certain family-level health resources because their families of origin may stigmatize, reject, or silence them on account of their sexual orientation. Semi-structured interviews were used to explore how participants in recovery constructed and coped with their experiences of stigma, family relationships, and alcohol and substance use. Participants (30 gay men ages 50 to 64) completed a questionnaire and interview. We used constructivist grounded theory method and minority stress theory as a theoretical framework to interpret the data. We identified the following themes: Internalization of Stigma, Changes in Coping Strategies, and Ongoing Stigma. Future research should explore how to incorporate familial support into gay men's recovery, address ongoing internalized stigma, and develop a social response to stigma, rather than leaving it to individuals to confront on their own. 相似文献

Record numbers of young African American males are released from juvenile detention, residential commitment, and prison facilities each year. Many challenges must be overcome for them to integrate back into their families and communities. Incorporating an Afrocentric cultural approach with concrete, comprehensive services such as education, training, employment housing assistance, substance abuse treatment, and family support could serve as a powerful tool for successful reentry. 相似文献

We assessed biogeochemical cycling of elements through residential household landscapes to evaluate the importance of annual
to decadal household-level decisions for element fluxes that contribute to urban and regional pollution. We combined a mailed
survey, vegetation measurements, and allometric and biogeochemical models to estimate fluxes and accumulation of carbon (C),
nitrogen (N), and phosphorus (P) in landscapes of 360 single-family homes in the Minneapolis-Saint Paul, Minnesota metropolitan
area. Carbon inputs and accumulation were strongly influenced by the presence of trees on the property. Nitrogen inputs to
the landscape exceeded estimated ecosystem demand for N on average by 51% and were dominated by N fertilizer application.
Because Minnesota state law restricts the use of P fertilizer, pet waste was responsible for 84% of P inputs to the landscape.
The results have implications for understanding sources of urban pollution and the potential flexibility (i.e., the potential
for change) in household behaviors such as tree planting, fertilization, and pet waste management that contribute to such
pollution. 相似文献

Industrialized Animal Production—A Major Source of Nutrient and Microbial Pollution to Aquatic Ecosystems 总被引:5,自引:0,他引:5
Livestock production has undergone massive industrialization in recent decades. Nationwide, millions of swine, poultry, and cattle are raised and fed in concentrated animal feeding operations (CAFOs) owned by large, vertically integrated producer corporations. The amount of nutrients (nitrogen and phosphorus) in animal manure produced by CAFOs is enormous. For example, on the North Carolina Coastal Plain alone an estimated 124,000 metric tons of nitrogen and 29,000 metric tons of phosphorus are generated annually by livestock. CAFO wastes are largely either spread on fields as dry litter or pumped into waste lagoons and sprayed as liquid onto fields. Large amounts of nitrogen and phosphorus enter the environment through runoff, percolation into groundwater, and volatilization of ammonia. Many CAFOs are located in nutrient-sensitive watersheds where the wastes contribute to the eutrophication of streams, rivers, and estuaries. There is as yet no comprehensive Federal policy in place to protect the environment and human health from CAFO generated pollutants. 相似文献

Motivated by long-standing debates between abstinence proponents and sceptics, we examine how socio-economic factors influence premarital first births via: (i) age at first sexual intercourse and (ii) the risk of a premarital first birth following the onset of sexual activity. Factors associated with an earlier age at first intercourse will imply more premarital first births owing to increased exposure to risk, but many of these same factors will also be associated with higher risks of a premarital first birth following onset. Our analyses confirm previous findings that women from disadvantaged backgrounds are younger at first intercourse and have higher premarital first-birth risks than women from more advantaged backgrounds. However, differences in onset timing have a strikingly smaller influence on premarital first-birth probabilities than do differences in post-onset risks. Our findings thus suggest that premarital first births result primarily from differences in post-onset risk behaviours as opposed to differences in onset timing. 相似文献

The present study examines the psychometric properties of a student-reported measure of school quality, the CFS Conditions for Learning Survey, to examine its utility as a cross-national comparative measure to evaluate UNICEF's Child Friendly Schools initiative. Factor analyses conducted on data from fifth- and sixth- grade students in 68 schools across the Philippines, Nicaragua, and South Africa revealed a core set of items that loaded highly onto each of the three dimensions of the CFS Conditions for Learning survey across all three countries. Formal tests established measurement invariance for a subset of these items, indicating that they were free from methodological bias across countries. However, meaningful differences in the country-specific structure and substantive interpretation of school quality were also detected. The results suggest that items in the CFS Conditions for Learning survey can be used to create both reliable cross-national and country-specific indicators of school quality and provide a blueprint for future psychometric work in the field of comparative child and family policy. 相似文献

Few empirical studies have focused on elder abuse in nursing home settings. The present study investigated the prevalence and risk factors of staff physical abuse among elderly individuals receiving nursing home care in Michigan. A random sample of 452 adults with elderly relatives, older than 65 years, and in nursing home care completed a telephone survey regarding elder abuse and neglect experienced by this elder family member in the care setting. Some 24.3% of respondents reported at least one incident of physical abuse by nursing home staff. A logistic regression model was used to estimate the importance of various risk factors in nursing home abuse. Limitations in activities of daily living (ADLs), older adult behavioral difficulties, and previous victimization by nonstaff perpetrators were associated with a greater likelihood of physical abuse. Interventions that address these risk factors may be effective in reducing older adult physical abuse in nursing homes. Attention to the contextual or ecological character of nursing home abuse is essential, particularly in light of the findings of this study. 相似文献
