In the housing unit method, population is calculated as the number of households times the average number of persons per household (PPH), plus the population residing in group quarters facilities. Estimates of households and the group quarters population can be derived directly from concurrent data series, but estimates of PPH have traditionally been based on previous values or estimates for larger areas. In our study, we developed several regression models in which PPH estimates were based on symptomatic indicators of PPH change. We tested these estimates using county-level data in four states and found them to be more precise and less biased than estimates based on more commonly used methods.  相似文献

Using data from Pakistan, India, Malaysia, Thailand, and the Philippines, we explore how gender context influences (1) husband-wife concordance in the demand for children and (2) the impact of each spouse's fertility preferences on contraceptive use. We also explore whether the husband's pronatalism can explain the wife's unmet need for contraception. The results suggest that gender context has little net effect on couples' concordance, but influences the relative weight of husbands' and wives' preferences in determining contraceptive use. Analysis of women's unmet need for contraception suggests that the husbands' pronatalism contributes to wives' unmet need, but only to a relatively small degree, especially in settings where unmet need is high. This is the case because the proportion of couples with differing fertility goals is small in most communities.  相似文献

To help practitioners bridge services to their clients who face family problems, this research aims to identify help-seeking behaviors among Vietnamese Americans who have experienced parent–child conflict and depression. The 2008 Asian Survey found that 46.3% of 572 Vietnamese Americans experienced parent–child conflict and 30.2% reported depressive symptoms. Having parent–child conflicts or depressive symptoms did not predict help-seeking from mental health professionals. Logistic regression results show that having parent–child conflict would increase the likelihood by 81.7% of a thinking that the problem will be naturally resolved; having depressive symptoms would increase the likelihood of seeking help from herbalists by 1.718 times and from medical doctors by 39.7%. Service strategies should include offering educational programs by multidisciplinary professionals with a focus on the natural aspect of building parent–child bonding.  相似文献

A review of empirical literature reveals improvements in service utilization and outcomes for women when substance abuse and child welfare services are integrated. The increased use of substances by women involved in the child welfare system has resulted in a call for integrated, coordinated, evidence-based practices. Since the late 1990s, specific system- and service-level strategies have been developed to coordinate and integrate the provision of substance abuse and child welfare services such that women are remaining in treatment longer and are more likely to reduce substance use and be reunited with their children. The strategies reviewed provide useful guidelines for developing components of effective, evidence-based programs for substance-involved women in the child welfare system.  相似文献

In this article, we examine some properties and extensions of a particular poverty index, which is already passingly familiar to poverty analysts. Our investigation leads to a new perspective on the family of additively decomposable and scale-invariant poverty indices and provides new insights into the class of poverty measures proposed by Foster et al. (Econometrica 52:761–766, 1984). Finally, our work leads to a clarification of the different roles of transfer properties and distribution sensitivity in poverty measurement.  相似文献

This study focused on foster parent perspectives of foster care privatization in the state of Florida. Ninety-nine members of Florida's foster parent associations were surveyed with a special attention toward their stance on privatization policy and their views of the local private agencies that deliver services in the privatized system. Results identified no clear consensus on the topic of privatization policy. Policy support was more likely to be seen among foster parents who had not served prior to privatization and among foster parents who viewed the local private agency to be competent and responsive. Views of local private agencies were most strongly influenced by the foster parents' satisfaction with foster parent training, their involvement in case decision-making, and the kindness of the foster care worker. These results have implications for practice in the privatized foster care system and for research in the evaluation of these systems.  相似文献

This study examines the role of abuse-specific maternal support in the association between parent depressive symptoms and child externalizing problems in a sample of children with a history of sexual abuse. In total, 106 mother-child dyads were studied. The association between maternal depressive symptoms and child delinquency behaviors was found to partially operate through abuse-specific maternal support, which was assessed via parent report. Implications of the findings for parenting programs are discussed, and future research directions are considered.  相似文献

Leisure, recreation, and play from a developmental context   总被引:1,自引:0,他引:1  
Participation in activities and experiences defined as play, recreation,and leisure has important developmental implications for youth. Elements and characteristics of leisure experiences contribute directly to the development of identity, autonomy, competence,initiative, civic duty, and social connections. Whether in informal or formal, appropriately structured and organized programs,leisure experiences can help facilitate adolescent development in these areas. For example, one of the defining elements of leisure is that it is characterized by free choice and self-determination. Programs that promote leadership, choice, autonomy, and initiative can help adolescents deal with developmental challenges associated with this age group. Leisure experiences can also promote civic engagement and provide important peer-to-peer, peer to-adult, and peer-to-community connections. The social context of leisure is important to adolescent development in that it provides opportunities to learn empathy, loyalty, and intimacy in their group activities, as well as to negotiate with peers, resolve conflict,and work together for communal goals. In addition, adolescents often report positive emotional experiences in leisure, which can serve as a relief from the stress they feel in other areas of their lives and contribute to positive psychological adjustment and well-being. A case study is used to show how planned, purposive programs can be used as critical components of efforts to contribute to adolescent development.  相似文献
