The Child Protection Mediation Program in Cook County, Illinois is the result of a collaborative effort on the part of the court, its stakeholders, and the attorneys involved in child protection cases. Child protection mediation empowers families and includes parents in many decisions impacting their children. It also helps judges to move children's cases through the legal system more rapidly and in a more efficient and humane manner. This results in children achieving more timely permanency. The program is sustained in part due to frequent outreach to, and input from, the program's consumers. These help to ensure that the program is meeting the diverse needs of the court, the families, and the professionals involved in the cases.  相似文献

The present study examined the association between witnessing interparental violence as a child, and the risk for perpetrating and being the victim of dating aggression as an adult, in an undergraduate sample. Specifically, this study tested a modeling hypothesis whereby witnessing a same sex parent vs. an opposite sex parent exclusively in the aggressor role would be more highly associated with risk for perpetrating dating aggression. Similarly, observing a same sex parent vs. an opposite sex parent as exclusively a victim of marital aggression would be associated with risk for being a victim of dating aggression. A same sex modeling effect was found for perpetration of dating aggression. Respondents who witnessed only their same sex parent perpetrate physical marital aggression were at increased risk for perpetrating physical dating aggression, whereas respondents who witnessed only their opposite sex parent perpetrate were not. A same sex modeling effect, however, was not found for being a victim of dating aggression. Rather, risk for victimization by dating aggression was associated only with witnessing bidirectional marital violence. Implications of these results, limitations of the present study, and ideas for future research are discussed.  相似文献

A case of a four-month-old male infant is described who was found unresponsive at home and brought to the emergency room. He lived for four days. During his hospital admission he was diagnosed by radiography with a fracture of the third lumbar vertebra that was presumed abusive in nature. Autopsy examination failed to confirm a fracture. However, a defect in the development of the vertebral bodies was discovered. He was diagnosed with possible failure of the notochord to regress, a condition with no significant sequelae. The cause of death was certified as sudden infant death syndrome after full investigation, and all autopsy studies were negative.  相似文献

The younger siblings of childbearing adolescents have poorer school outcomes and exhibit more internalizing and externalizing problems compared to their peers without a childbearing sister. We test a model where living with an adolescent childbearing sister constitutes a major family stressor that disrupts mothers' parenting and well-being, and through which, adversely affect youths' adjustment. Data came from 243 Latino younger siblings (62% female, M age 13.7 years) and their mothers, 121 of whom lived with a childbearing adolescent sister and 122 of whom did not. Individual fixed-effects models controlled for earlier measures of each respective model construct, thereby reducing omitted variable bias from pre-existing group differences. Results show that, for boys, the relationship between living with a childbearing adolescent sister and youth outcomes was sequentially mediated through mothers' stress and parenting (i.e., monitoring and nurturance). For girls, however, the relationship was mediated through mothers' monitoring only. Findings elucidate the within-family processes that contribute to the problematic outcomes of youth living with childbearing adolescent older sisters.  相似文献

Despite evidence that neighborhoods confer both risk and resilience for youth development, the existing neighborhood research has a number of methodological limitations including lack of diversity in neighborhoods sampled and neighborhood characteristics assessed. The purpose of this study was to address these methodological limitations of existing research and to examine the relationship of neighborhood structural and social characteristics to family-level social processes and teacher-reported social competence during early adolescence. The study sample of 3,624 fifth graders (51?% girls) was ethnically diverse, including roughly even proportions of non-Hispanic White, non-Hispanic Black, and Hispanic youth. Neighborhood measures included economic disadvantage derived from the U.S. Census, physical and social disorder obtained by direct observation, and social capital from parental reports. Family-level social processes included parent reported family cohesion and youth reported maternal and paternal nurturance. We found that neighborhood factors significantly associated with youth social aggression and social competence but not social withdrawal, after controlling for individual demographic characteristics and parenting factors. There was limited evidence of moderation of family influences by neighborhood characteristics as well as the moderation of neighborhood effects by children’s gender. Neighborhood physical disorder was associated with increased social aggression among boys but with increased social withdrawal among girls. Implications of the study’s findings for research on neighborhoods and adolescent development and the development of preventive interventions are discussed.  相似文献
