One-hundred and fifty-six children were randomly evaluated at an inner-city juvenile/family court. These children were removed from their parent's custody subsequent to a finding of severe child maltreatment. From our original sample of 156 children, 62 met strict criteria for Post Traumatic Stress Disorder (PTSD). Fifty-two of these 62 were successfully recruited and participated in the 2 year re-examination. Each PTSD diagnosis was conferred by the Diagnostic Interview for Children and Adolescents (DICA). From our sample of 52 PTSD children re-examined after 2 years, 17 (32.7%) retained the full PTSD diagnosis, while 67.3% did not meet criteria.  相似文献

The problem of the underrepresentation of girls in science in Australian schools is often attributed to their poor performance. Yet the role of both the home and the school in affecting female science achievement is rarely examined empirically. The comprehensiveness of the Second International Science Study database provided an excellent opportunity to investigate the presence of gender differences in science achievement. Although previous studies of gender differences in science achievement have relied on methodology that has not adequately accounted for the school effects, this study used the design effect and hierarchical linear modeling (multilevel analysis) to explore whether there were significant gender differences. The relative contribution of schools to student achievement was examined, and school-level differences were found to contribute significantly toward explaining variations in student performance. Although statistically significant sex differences were found in physics achievement for 10-year-old, 14-year-old, and year-12 students, school effects were much more powerful in explaining student differences (9–19%) when compared with gender (3%).  相似文献

A number of policy proposals have recently been presented that seek to address the problem of declining productivity growth. Many of these are aimed at encouraging private R&D spending through tax incentives. This paper first reviews some of these proposals, then evaluates tax incentives per se as a policy tool for encouraging R&D growth, and finally offers suggestions for redesigning R&D related tax incentive policies.  相似文献

What the existing organization of schooling presupposes...is that in consumption terms, the world consists of equally powerful individual actors. Such, of course, is not the case in a hierarchically ordered capitalist system, where labour and capital, and indeed different forms of both, have differential access to resources enabling them to consume. By largely intervening only in provisional relations, the state fails to recognize the central dynamic of education ‐‐ that provision and consumption are not coterminous. In essence, state intervention does not go far enough. (Lynch, 1989, p.127)  相似文献

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups.  相似文献

The role that affective states play in learning was investigated from the perspective of a constructivist learning framework. We observed six different affect states (frustration, boredom, flow, confusion, eureka and neutral) that potentially occur during the process of learning introductory computer literacy with AutoTutor, an intelligent tutoring system with tutorial dialogue in natural language. Observational analyses revealed significant relationships between learning and the affective states of boredom, flow and confusion. The positive correlation between confusion and learning is consistent with a model that assumes that cognitive disequilibrium is one precursor to deep learning. The findings that learning correlates negatively with boredom and positively with flow are consistent with predictions from Csikszentmihalyi's analysis of flow experiences.  相似文献
