From a social disorganization standpoint, neighborhood residential instability potentially brings negative consequences to parent–child relationship qualities, but family social support and racial/ethnic identity may modify this association. Using data (n = 3,116) from the Project on Human Development in Chicago Neighborhoods, this study examines associations between neighborhood residential instability and parent–child warmth and conflict, whether family social support moderates associations between residential instability and parent–child relationships, and variation by race/ethnicity. Multilevel models reveal that residential instability undermines parent–child relationship qualities, particularly for non‐White individuals. Family support is a protective factor for families in less stable neighborhoods and specifically buffers the association between neighborhood residential instability and reduced parent–child warmth. Among Hispanics, family support mitigates the association between residential instability and heightened parent–child conflict. Findings highlight residential instability as a detriment to parent–child relationships; families in unstable neighborhoods may benefit from family social support. 相似文献

Numerous community indicator projects have been developed over the past 30 years and are now present in many countries including the United States, Canada, United Kingdom, Europe, Australia, New Zealand and South America. However, creating influence and action using community indicators requires long-term effort strengthened by partnership, policy applications, training and research. This paper provides a reflective case study analysis that reviews the development of the community indicator system of Community Indicators Victoria in Australia. The analysis includes a review of best practice indicator principles guiding the development of current and future community indicator systems and describes how these factors influenced the development, establishment, and expansion of the Community Indicators Victoria system. 相似文献

The antecedents, correlates, and consequences of adolescent employment were investigated in a sample of 251 low‐income, African American youth that were followed since birth. The youth (age: M at preschool = 4.89, SD= .70; M at adolescence = 16.44, SD= .66; M at transition to adulthood = 19.36, SD= .76; and M at early adulthood = 27.67, SD= .75) were the firstborn children of African American teenage mothers who gave birth in Baltimore in the 1960s. Analyses examined the antecedents and correlates of age of entry into employment and stability of employment during adolescence. The associations of adolescent work experiences with subsequent adult education and employment outcomes also were considered. Findings indicate that among this sample of low‐income, African American youth, those who repeated a grade in school during middle childhood were more likely to enter the workforce at later ages than their peers who did not repeat a grade. The small subset of adolescents who never worked (n= 12) appear to be markedly more disadvantaged than their peers who worked. At the transition to adulthood, adolescents who entered the workforce earlier were more likely to complete high school than their peers. In addition, stable employment during the adolescent years had more beneficial effects on young men's chances of attending college than young women's postsecondary education. This pattern of findings is consistent with ethnographic accounts of adolescent employment among poor, minority, urban youth. 相似文献

We examine the effects of mothers' strategies of combining employment and welfare receipt during the first 3 years of their child's life on the child's cognitive development, behavior problems, and home learning environment at ages 5 to 6. We compare the child outcomes of those mothers who were continuously employed and received no welfare with (a) those who worked some or all of the 3 years and also received public assistance and (b) those who were totally dependent on public assistance. We studied children in single‐parent families (N= 1271 ) living below 200% of the poverty threshold using data from the National Longitudinal Survey of Youth—Child Supplement. No negative association was found on most child outcomes with a mother's employment whether or not it was combined with public assistance. However, mothers' not working at all and receiving financial support solely from AFDC was associated with negative child outcomes. We discuss the implications of these findings for the possible effects of the new welfare laws on families and young children. 相似文献

A framework for the analysis of manufacturing systems operating under a production authorization card (PAC) system is outlined. The PAC system provides a single model, which encompasses a broad variety of control strategies, including Kanban and CONWIP. This paper describes a framework for the performance analysis and comparison of both specific and families of control strategies. The framework starts with system performance measures estimated by simulation. These simulations in turn provide training data for neural network metamodels. The metamodels allow for a variety of analysis and optimization approaches, including the construction of optimal policy curves, which can provide considerable insight into the systems under study. 相似文献

Cet article présente les résultats d'une étude qui avait pour but de mesurer les repercussions de la loi C-127 sur la manière de procéder de l'appareil policier et judiciaire de Winnipeg dans les cas de violence sexuelle. La nouvelle loi ayant comme objectif de corriger certaines failles dans la procédure juridictionnelle, les auteurs ont opté pour l'analyse de régression logistique afin d'examiner les conséquences de plusieurs variables indépendantes sur le nombre des inculpations et des condamnations, et ce avant et après l'adoption de la loi. Cette méthode nous a permis de déterminer si la réforme de la loi sur le viol a conduit à des changements dans la manière dont ces variables indépendantes influent sur les inculpations et condamnations. La recherche tend à démontrer que la réforme n'a eu qu'un effet modéré sur l'examen des cas de violence sexuelle. This paper presents the results of an evaluation of the impact of Bill C-127 on the processing of sexual assault cases through the criminal justice system in Winnipeg. Because the law was intended to change the way in which sexual assault cases were treated by the courts, the authors employed logistic regression to examine the impact of several independent variables on charges and convictions before and after the new legislation. Logistic regression made it possible to determine whether the rape reform legislation led to changes in the way these independent variables affect charge and conviction. The research suggests the legislative reform has had only a modest impact on the treatment of sexual assault cases. 相似文献

The relations between the Norwegian Child Welfare Services (CWS) and various migrant groups are notably strained. Numerous media accounts and a growing body of research reveal that many migrants to Norway fear the CWS. By combining quantitative and qualitative analyses of media accounts, this paper addresses the historical evolvement of such strained relations in Norway. Previous research has neglected this aspect. Findings show that migration issues related to the CWS have been topics of public debate in Norway for three decades, with foster care being a particularly intractable concern. With the onset of the decade beginning in 2010, however, matters have intensified and taken on transnational dimensions. In the discussion of our findings, we emphasize in particular how digital and social media have contributed to the recent changes. 相似文献
