The use of standardized tools to assess risk for children is mandatory in the child protection sector in Ontario. Factors that can be used specifically to assess the risk of lethality in exposure to domestic violence (DV) cases, however, are largely missing from these tools. Using data from an online survey of 138 child protection workers in Ontario, the current study examines practitioners' risk assessment and safety planning practices with DV cases. Findings provide an overview of the frequency of risk assessment and management strategies within various environmental contexts (e.g., urban and rural) and populations (e.g., indigenous and immigrants/refugees). According to the practitioners sampled, assessing and managing risk are frequently and consistently completed across the province, although specific strategies and challenges vary. Although mandatory provincial child protection tools are commonly used, some workers report using other specific DV risk assessment tools to complement their own measurement of risk and planning for safety. Respondents emphasized the importance of working collaboratively with families and professionals in other sectors to address risk. Implications for future research include exploring the barriers and challenges of using DV‐specific risk assessments in child protection and factors contributing to these challenges as identified by practising child protection workers.  相似文献

This paper adopts a qualitative case study on the generalist service delivery model of I‐Care, a Durban‐based non‐governmental organization that works with male street children. Fifteen face‐to‐face interviews were conducted with 10 I‐Care employees and 5 former street children. A focus group was set up with I‐Care employees. Although existing literature is forthright about a generalist approach for children at risk, it remains unclear how to implement this approach in practice. This paper reviews a continuity of 5 fundamental social work practices for working with street children: (a) outreach work, (b) child–family and child–community mediation, (c) transitory care centres and programmes, (d) brokerage, and (e) mentorship and follow‐ups. The study analyses how these practices contribute to the capability and agency expansion of the street children and outlines challenges that service providers and former street children experience. The main challenges acknowledged are balancing between the agency and protection of street children and the adaptation of children to street life. The study proposes intervention strategies to overcome these challenges.  相似文献

This study investigates whether the type of parental permission affects prevalence estimates for risk behaviors from the national 2001 Youth Risk Behavior Survey. Participants were 13,195 students from 143 schools, of which 65% used passive permission and 35% active permission. Student participation rates were 86.7% in passive permission schools and 77.3% in active permission schools. For 24 of 26 behaviors tested, no significant differences were seen in the prevalence of risk behavior by type of parental permission. As long as high response rates are obtained, type of parental permission does not affect prevalence estimates for risk behaviors that are based on self-report.  相似文献

We discuss the simple model pioneered by Barclay and Holderness (1989, Journal of Financial Economics 25: 371–395) and recently reproposed by Dyck and Zingales (2004a, Journal of Finance 2, 537–600; 2004b Journal of Applied Corporate Finance 16, 51–72) in order to measure the value of control in countries, like Italy, where transfer of control is regulated by law. We demonstrate that it is possible to broaden the application of B&;H approach to block trades followed by mandatory tender offers and we show the conditions under which we may obtain significant measures of private benefits also when voluntary tender offers are considered. In order to test for our theoretical predictions, we analyse the pricing of 27 control transactions involving the common stock of Italian listed corporations between 1993 and 2003. We find that block-transaction (tender) premium equals on average 8% of the firm’s equity value in the case of pure block-trades, 9% in the case of block trades followed by a mandatory tender offer, while it increases to 18% in the case of voluntary tender offers. The results suggest that, in the case of block trades followed by a mandatory tender offer, the acquirer does not transfer a larger portion of its surplus. This doesn’t take place in the case of voluntary tender offers, in which the raider’s bargaining power collapses. Our estimate of the control premium is sensibly lower than that presented in previous studies based on similar methodologies, providing up-to-date evidence for control stake valuation purposes and for comparison with cross country studies aiming at assessing the quality of rules devoted to minority shareholders’ protection. We also perform a cross-sectional regression analysis of private benefits of control and confirm some of the findings presented in the previous literature: particularly, we find evidence of a positive relation between the magnitude of private benefits of control and the target’s degree of stock-pyramiding. We also find that foreign acquirers and financial investors seem likely to face greater difficulties in extracting private benefits of control.  相似文献

Bridging Refugee Youth and Children's Services(BRYCS), a public-private partnership between the federal Office of Refugee Resettlement, Lutheran Immigration and Refugee Service, and the United States Conference of Catholic Bishops, provides national technical assistance to public child welfare. After a series of "community conversations," BRYCS identified a lack of knowledge among child welfare staff about newcomer refugees, negative stereotypes, and a fear of child protective services among refugees. BRYCS initiated a number of technical assistance initiatives, including a pilot cross-service training project in St. Louis to strengthen collaboration between child welfare and refugee-serving agencies. This article details the lessons learned from this training and recommends changes in policy and practice.  相似文献

This study examined the resettlement experiences of unaccompanied Sudanese refugee youth placed in foster care from the perspectives of the youth, foster parents, and agency caseworkers. Youth experienced considerable success. The challenges of adjusting to school and family life, however, suggest a need for funding to support more intensive educational services, more cultural training and support for foster parents and school personnel, and flexibility to provide services in more culturally appropriate modalities.  相似文献

Deciding which people to tell about sexual assault is an important and potentially consequential decision for sexual assault survivors. Women typically receive many different positive and negative reactions when they disclose sexual assault to social support sources. A diverse sample of adult sexual assault survivors in the Chicago area was surveyed about sexual assault experiences, social reactions received when disclosing assault to others, attributions of blame, coping strategies, and PTSD. Analyses were run to identify demographic, assault, and postassault factors differentiating women disclosing to informal support sources only from those disclosing to both informal and formal support sources. Women disclosing to both formal and informal support sources experienced more stereotypical assaults, had more PTSD symptoms, engaged in less behavioral self-blame, and received more negative social reactions than those disclosing to informal support sources only. Implications for future research and intervention are discussed.  相似文献

Using the 1992–1993 Baccalaureate and Beyond Longitudinal Study, with the 1997 follow-up, the parental decision to borrow and, for borrowers, the level of borrowing for dependent children’s college education was analyzed. Parents with smaller household size and those being college graduates borrowed greater amounts. White parents borrowed greater amounts than their non-White counterparts. The age of the student, dependent students’ income and parents’ cash and savings each had a significant negative impact on the amount parents borrowed, while home equity was a significant positive factor. Greater college costs significantly increased parents’ decision to borrow, as well as the borrowed amount. Greater amounts of grants significantly reduced the amount borrowed.  相似文献

Nationwide efforts to protect the public against the health effects of secondhand smoke have prompted college and university administrators to adopt more restrictive smoking policies. Some campus officials are concerned that new policies will lead to student backlash, increased staff workloads, and an increased economic burden. To understand the impact of smoke-free residence hall policies, we conducted key informant interviews and gathered archival data at 3 large state universities. The implementation of smoke-free residence hall policies imposed little economic burden. We noted positive impacts in several key areas, including decreased damage to residence hall buildings, increased student retention, and improved enforcement of marijuana policies. Increased costs, such as the purchase of outdoor cigarette receptacles, were outweighed by the benefits. Findings from this study should encourage college and university administrators to enact smoke-free residence hall policies.  相似文献
