Literature on family drug treatment courts (FDTCs) suggests that parental participation in these courts is associated with improved substance abuse treatment and child welfare system outcomes. Despite these beneficial outcomes, FDTCs serve only 7‐10% of eligible child welfare involved families. As part of a FDTC evaluation, this FDTC site sought to provide stakeholders with information about costs and benefits. Considering the program costs alongside the cost avoidance from reduced time in foster care, this analysis determined that FDTC participation resulted in a net savings per child of $9,710. The cost component of the evaluation proved valuable, challenging, and informative.  相似文献

This study explores the role of income for young people with experience in foster care transitioning to adulthood. It draws on in-depth structured interviews with eight staff members and 38 current and former foster youths age 18 years and older, who were participants in an innovative program to build their assets and financial capability. Interviews took place in four sites in three states. This study illuminates how those with experience in foster care seek to obtain and manage money to transition successfully to adult financial roles. Findings suggest that early and practical experiences with money are important for gaining financial capability. The study also highlights the need for child welfare professionals to develop expertise in financial literacy and understand the pitfalls that lie in both traditional and nontraditional financial services. By deepening understanding among staff of the economic realities facing the young people today, child welfare agencies will be more likely to prepare former foster youths for life on their own.  相似文献

Video data received for analysis often come in a variety of file formats and compression schemes. These data are often transcoded to a consistent file format for forensic examination and/or ingesting into a video analytic system. The file format often requested is an MP4 file format. The MP4 file format is a very common and a universally accepted file format. The practical application of this transcoding process, across the analytical community, has generated differences in video quality. This study sought to explore possible origins of the differences and assist the practitioner by defining minimum recommendations to ensure that quality of the video data is maintained through the transcoding process. This study sought to generate real world data by asking participants to transcode provided video files to an MP4 file format using programs they would typically utilize to perform this task. The transcoded results were evaluated based on measurable metrics of quality. As the results were analyzed, determining why these differences might have occurred became less about a particular software application and more about the settings employed by the practitioner or of the capabilities of the program. This study supports the need for any video examiner who is transcoding video data to be cognizant of the settings utilized by the programs employed for transcoding video data, as loss of video quality can affect analytics as well as further analysis.  相似文献

Research in developmental psychology highlights youth’s self-schemas as one possible pathway to improve adolescents’ functioning and promote positive developmental outcomes. Despite this, the trajectory of positive and negative self-schemas is relatively understudied. This study addresses this limitation by empirically examining the trajectory of self-schemas in a community sample of 623 youth (M?=?13.04 years; 54% female; 49% African American, 4% Biracial, 47% European American) who were followed over a seven-year period. Caregivers completed measures of parenting practices, maternal rumination and negative inferential style, and adolescents completed a computerized behavioral task assessing self-schemas (i.e., mental frameworks that guide attention, interpretation, and memory of one’s experiences). Multilevel growth curve modeling results demonstrated a quadratic slope for negative self-schemas and no mean-level change for positive self-schemas. These trajectories did not vary by gender or racial group. However, parenting factors differentially influenced the trajectories. Specifically, higher levels of parental involvement at baseline, or an active interest and engagement in a child’s experiences and activities, related to lower levels of negative self-schemas during adolescence. Additionally, higher levels of parental rumination and parental negative control at baseline related to lower levels of youth positive self-schemas at baseline. These findings contribute to models of youth cognitive development.

ABSTRACT

This article focuses on the forgotten voices of marginalized feminist mothers—those active in welfare rights groups. These activists were primarily poor single mothers who understood motherhood differently from more mainstream feminists. Whilst they echoed mainstream feminist demands for childcare, they also supported women's right to stay at home with their children, emphasizing the role of the state. This presented a serious class-based critique in a society that increasingly saw stay-at-home motherhood as a middle-class option. This article focuses upon working-class mothers' groups, thus problematizing dominant feminist discourses and developing a more diverse history of second wave feminism in Canada.  相似文献

Is empowering peace education primarily about providing individuals with skills to respond to violence they experience and capabilities to enhance their own lives? Or is inspiring social transformation to alter forms of injustice that contribute to violence an equally valid and important dimension of an empowering peace education program? This article draws upon the authors’ experiences researching peace education programs implemented by local nongovernmental organizations (NGOs) in two different contexts: Jamaica and Peru. The basis for comparison is grounded in the discourse key actors in these NGOs utilized in reference to their respective educational initiatives, explicitly emphasizing empowerment for marginalized groups. Using critical qualitative techniques and troubling the idea of ‘empowerment,’ the authors analyze the discourse of empowerment to look beyond explicit truth claims and unveil tacit assumptions regarding the purpose and desired outcomes for the beneficiaries of their respective programs. The authors interrogate what definitions of empowerment – social and/or individual – the program stakeholders envision as well as how they believe such empowerment comes about. The study’s findings contribute to the need to critically unpack the commonly uncritical use of the term ‘empowerment’ as necessarily directed toward addressing social inequalities and altering unjust power relations.  相似文献

Although lesbian, gay, and bisexual (LGB) youth with a history of homelessness (running away or being evicted from their homes by parents) report more psychological symptoms than homeless heterosexual peers, it is unclear whether symptoms are due to homelessness, given the absence of a non-homeless comparison group. This study longitudinally investigates whether LGB youth with a history of homelessness report more subsequent psychological symptoms than non-homeless LGB youth and examines potential mediators of any such relationships. Of the 156 LGB youth interviewed (49% female; 78% non-White), 48% reported past homeless experiences. Homelessness was associated with subsequent symptoms of anxiety, depression, conduct problems, and substance abuse and to changes in symptoms over time even after controlling for childhood sexual abuse and early development of sexual orientation. Stressful life events, negative social relationships, and social support from friends mediated the relationships between homelessness and symptomatology. These findings suggest the need for interventions to reduce stress and enhance social support among LGB youth with a history of homelessness in order to reduce psychological symptoms.  相似文献
