Compared to the sibling literature of the general population, little is known about sibling relationships of youth in foster care. The current study aimed to report on sibling relationships among youth in foster care, and investigate the potential protective nature of sibling relationships of those who have experienced trauma on the expression of internalizing symptoms among a nationally representative sample of 152 adolescents in foster care. Results indicated that the large majority of the sample was currently separated from their sibling. Of those who were not living with their sibling, nearly three quarters saw their sibling monthly or less frequently with one third of the sample reporting never having any contact with their sibling. In addition, bootstrapping methods were used to determine if sibling relationships mediated the effect of trauma on internalizing symptoms. Results indicated that a positive sibling relationship significantly mediated this relationship. Implications of these findings are discussed.  相似文献

The study's purpose is to determine the efficacy of the Tomatis Method of auditory stimulation as a therapeutic intervention for Auditory Processing Disorders (APD). Forty-one subjects (18 females, 23 males; 4.3–19.8 years old) were evaluated for APD. Performance on standardized tests indicated weaknesses with auditory processing skills. Each subject participated in a 90-hour Tomatis Method protocol and, once completed, each subject was re-evaluated to measure improvement. All subjects demonstrated improvement with skills of immediate auditory memory, auditory sequencing, interpretation of directions, auditory discrimination, and auditory cohesion. Pre- and post-treatment comparison indicated statistically significant differences in the aforementioned skills. These findings suggest that the Tomatis Method of auditory stimulation can be effective as an intervention strategy for APD.  相似文献

Changing an established role in a classroom is difficult. It involves constructing a new set of relations within a community. In this article we investigate how students with newly developed interest and experience in programming developed outside the classroom pick up and establish their roles as experts in programming within the classroom community. More specifically, we focus on how two 11-year-old software designers shifted their established roles in their classroom to gain status as expert programmers. We use an identity lens to understand how peer expertise was established in the context of a classroom community, adopting a multifaceted perspective of identity by focusing on an individual's narrativization of self, full, or peripheral participation among a group of people, and individuals' social recognition by others. Our findings point to the importance of both positive positioning by authority figures in the classroom and activities and roles that provide opportunities to establish intersubjectivity among peers in facilitating students' identities as experts in the classroom. Students' willingness to take up a new position in the established activity system also played a role. We consider implications of how making roles flexible within classroom stratification may provide opportunities for more students see themselves as experts.  相似文献

Collaborative and participatory research methods reflect ideals to undertake research in consultation and partnership with communities and to advance community empowerment and capacity. They offer ethical and practical approaches for conducting research addressing socioeconomic and health disparities particularly in marginalised or vulnerable communities. Peer‐interviewing is one such participatory strategy employed in studies involving hard‐to‐reach populations. However, while the value of peer‐interviewing for researchers is noted in the methodological literature, there are few discussions that critically examine the benefits and challenges of using peer‐researcher approaches, either for the interviewers themselves or the communities they represent. This study reports the findings from a qualitative study that explored the experiences of peer‐interviewers who were involved in undertaking community surveys of residents in the socioeconomically disadvantaged neighbourhoods in which they lived. We discuss the benefits and challenges that participants reported from their involvement.  相似文献

This paper draws on an archive of media texts that document the making of the film Out of the Blue. Within these media accounts are statements made by a group of residents resisting the film project, and the film‐makers responding to this resistance. We employ a Foucauldian informed discourse analysis to read these statements of resistance as a starting point to examine the power relations within contemporary knowledge generation processes of creative industries. We theorise creative industries as a discursive object located at the intersection of three discursive formations: ‘creativity’, ‘enterprise’ and ‘place’. Through analysing the particular place–identities of Aramoana engaged by the resisting residents and the film‐makers, we are able to suggest how this film project came to be discursively constituted as creative enterprise. In so doing, we find that the resisting residents’ statements work to disrupt the taken‐for‐granted ‘goodness’ of film enterprise, and creative industries more generally.  相似文献

This paper seeks to refocus the attention of environmentalists on the importance of population trends to environmental sustainability and identifies prevention of unintended pregnancy as potential common ground for environmentalists and family planning advocates. The health and other welfare benefits of preventing unintended pregnancy are felt most keenly by individual women, men, and their families. At the same time, however, preventing unwanted pregnancies usually results in smaller family size, an important factor in slowing population growth and, as a result, a source of broader benefits—including environmental benefits—to society.  相似文献

In 2001, the U.S. Environmental Protection Agency derived a reference dose (RfD) for methylmercury, which is a daily intake that is likely to be without appreciable risk of deleterious effects during a lifetime. This derivation used a series of benchmark dose (BMD) analyses provided by a National Research Council (NRC) panel convened to assess the health effects of methylmercury. Analyses were performed for a number of endpoints from three large longitudinal cohort studies of the neuropsychological consequences of in utero exposure to methylmercury: the Faroe Islands, Seychelles Islands, and New Zealand studies. Adverse effects were identified in the Faroe Islands and New Zealand studies, but not in the Seychelles Islands. The NRC also performed an integrative analysis of all three studies. The EPA applied a total uncertainty factor (UF) of 10 for intrahuman toxicokinetic and toxicodynamic variability and uncertainty. Dose conversion from cord blood mercury concentrations to maternal methylmercury intake was performed using a one-compartment model. Derivation of potential RfDs from a number of endpoints from the Faroe Islands study converged on 0.1 microg/kg/day, as did the integrative analysis of all three studies. EPA identified several areas for which further information or analyses is needed. Perhaps the most immediately relevant is the ratio of cord:maternal blood mercury concentration, as well as the variability around this ratio. EPA assumed in its dose conversion that the ratio was 1.0; however, available data suggest it is perhaps 1.5-2.0. Verification of a deviation from unity presumably would be translated directly into comparable reduction in the RfD. Other areas that EPA identified as significant areas requiring further attention are cardiovascular consequences of methylmercury exposure and delayed neurotoxicity during aging as a result of previous developmental or adult exposure.  相似文献
