Individuals in the dependency system believe that it is important to have parties present at early decision-making hearings without much empirical support. This paper examines how involvement of mothers, fathers, and their respective legal representatives at early decision-making hearings (i.e., preliminary protective, adjudication, disposition, and first review) influences reunification in juvenile dependency cases. Cox proportional-hazard models indicate the likelihood over time of returning children to the parents they were removed from was significantly higher when the mother and the mother's attorney was present at early decision-making hearings. Results also indicate that the presence of the father significantly increased the likelihood of returning children to the parents they were removed from at only two specific case events. The presence of the father's legal representative was a significant predictor of reunification at the disposition hearing only. Implications for theory and policy are discussed.  相似文献

Some volatile N‐nitrosamines, primarily N‐nitrosodimethylamine (NDMA), are recognized as products of drinking water treatment at ng/L levels and as known carcinogens. The U.S. EPA has identified the N‐nitrosamines as contaminants being considered for regulation as a group under the Safe Drinking Water Act. Nitrosamines are common dietary components, and a major database (over 18,000 drinking water samples) has recently been created under the Unregulated Contaminant Monitoring Rule. A Monte Carlo modeling analysis in 2007 found that drinking water contributed less than 2.8% of ingested NDMA and less than 0.02% of total NDMA exposure when estimated endogenous formation was considered. Our analysis, based upon human blood concentrations, indicates that endogenous NDMA production is larger than expected. The blood‐based estimates are within the range that would be calculated from estimates based on daily urinary NDMA excretion and an estimate based on methylated guanine in DNA of lymphocytes from human volunteers. Our analysis of ingested NDMA from food and water based on Monte Carlo modeling with more complete data input shows that drinking water contributes a mean proportion of the lifetime average daily NDMA dose ranging from between 0.0002% and 0.001% for surface water systems using free chlorine or between 0.001% and 0.01% for surface water systems using chloramines. The proportions of average daily dose are higher for infants (zero to six months) than other age cohorts, with the highest mean up to 0.09% (upper 95th percentile of 0.3%).  相似文献

This paper argues that infant and child observation is not only valuable as part of social work training for work with children and families but that it has a wider value in equipping workers with assessment skills relevant in all areas of social work, including care management. It describes the introduction of infant and child observation as a required component of the BA/Diploma in Social Work at The University of Reading and the effect on students' learning and their practice skills. It shows how child observation festers the development of reflective practice, enabling workers to look beyond the presenting problem and to understand the situation as a whole. The resulting intervention is then more likely to be appropriate in meeting a client's needs.  相似文献

This study examined the relationship between evaluations of academic support services and student athletes’ career decision‐making self‐efficacy. One hundred and fifty‐eight NCAA athletes (68% male) from 11 Division I teams completed measures of satisfaction with their academic support services, career decision‐making self‐efficacy, general self‐efficacy, and locus of control. Results indicated that evaluations of academic support services were positively related to levels of career decision‐making self‐efficacy. In addition, this relationship was moderated such that student athletes with lower levels of general self‐efficacy and internal locus of control benefited more from positive experiences with academic support services. Limitations and implications are discussed.  相似文献

This article presents data from a secondary analysis of a 1992 survey of graduate social work faculty to identify their views of the importance of content on diverse populations and types of oppression. The large majority of respondents rated content on several population groups and types of oppression to be important or very important. In most categories, however, the respondents rated including content on populations rather than on types of oppression to be more important, at a statistically significant level. The authors discuss the implications of this finding and place it in the context of current writings on multicultural social work.  相似文献

The negative attitudes fostered by political rhetoric against asylum seekers create significant problems when asylum seekers are housed within communities. Much of the community's opposition focuses on the perceived economic and social impacts of large numbers of asylum seekers. However, we currently lack research on the local economic and social impacts of asylum seekers. As a contribution to this evidence base our paper outlines a South Australian case study of the impact of a low security immigration detention facility on the local economy, health services and social cohesion. Our impact assessment found that community concerns were not borne out. There were increases in employment and local expenditure, no reduction in health care services or access, and tensions between residents subsided, as did initially strong reactions against the asylum seekers themselves. The minimal impacts were due to the government and community interventions such as seeking local contracts and providing onsite health services. This case study is used to provide some guidelines for other communities to effectively target the fears that matter most to the community – either through disseminating information that reduces fears and myths, or through planning and interventions that minimise negative impacts and enhance positive benefits. In this way, the arrival of asylum seekers can potentially become one that benefits all community members.  相似文献

A theory of lesbian, gay, bisexual, and transgender (LGBT) ally identity development integrated the following theories—multicultural counseling theory (MCT), self-concept formation theory (SCFT), and social identity theory (SIT)—to design a course to train heterosexual students to be allies to LGBT communities. Students participated in interviews and activities with LGBT persons, presented seminars on LGBT topics, and wrote papers about these experiences. An analysis of their reactions suggested that initially, students perceived themselves as lacking credibility to be allies. After interacting with LGBT communities, students gained the knowledge, attitudes, and skills they needed to be confident in supporting and advocating for LGBT persons.  相似文献

Several significant changes in the diagnostic criteria for gambling disorder occurred with the newest revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The changes aim to simplify and streamline the diagnosis without compromising its validity. Yet many of the tools used to screen and diagnose the disorder are based upon the prior fourth edition of the DSM, and it is unclear how they perform with the revised diagnostic criteria. The aim of this study is to examine the psychometric properties of a common pathological gambling screen, the Brief Biosocial Gambling Screen (BBGS; Gebauer, LaBrie, & Shaffer, 2010), in the context of DSM-5 criteria within a help-seeking sample. Gamblers calling a helpline (N = 2750) completed a semi-structured interview assessing DSM-IV past-year pathological gambling criteria with a trained clinician. Sensitivity, specificity, positive predictive value, negative predictive value and differences by sex were examined. The BBGS had high sensitivity as well as positive and negative predictive values. In light of the revisions made to the diagnostic criteria in DSM-5, the BBGS remains a psychometrically supported instrument for gambling disorder.  相似文献

This article examines serials workflow adaptation at Notre Dame University Libraries in the context of migration from the NOTIS LMS to the Aleph 500 ILS. In addition to detailing three specific workflows—check-in, claiming, and binding—in NOTIS versus Aleph 500, the authors discuss the workflow adaptation process in general. Emphasis is placed not only on the pragmatic side of the process but also on its psychological aspects. The last section of the article outlines several suggestions for how to deal with expectations for workflow that simply do not match a new system's functionality.
