Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results indicated a general pattern of an increase in stereotype knowledge, the importance and positive evaluation of one's own gender category, and rigidity of beliefs between the ages of 3 and 5. Moreover, the stability phase, rather than full constancy, mediated some of these relations. After age 5, rigidity generally decreased with age, with relations primarily mediated by consistency. 相似文献

Individual, family, and neighborhood factors distinguish resilient from non-resilient maltreated children: a cumulative stressors model 总被引:2,自引:0,他引:2
OBJECTIVE: Children who are physically maltreated are at risk of a range of adverse outcomes in childhood and adulthood, but some children who are maltreated manage to function well despite their history of adversity. Which individual, family, and neighborhood characteristics distinguish resilient from non-resilient maltreated children? Do children's individual strengths promote resilience even when children are exposed to multiple family and neighborhood stressors (cumulative stressors model)? METHODS: Data were from the Environmental Risk Longitudinal Study which describes a nationally representative sample of 1,116 twin pairs and their families. Families were home-visited when the twins were 5 and 7 years old, and teachers provided information about children's behavior at school. Interviewers rated the likelihood that children had been maltreated based on mothers' reports of harm to the child and child welfare involvement with the family. RESULTS: Resilient children were those who engaged in normative levels of antisocial behavior despite having been maltreated. Boys (but not girls) who had above-average intelligence and whose parents had relatively few symptoms of antisocial personality were more likely to be resilient versus non-resilient to maltreatment. Children whose parents had substance use problems and who lived in relatively high crime neighborhoods that were low on social cohesion and informal social control were less likely to be resilient versus non-resilient to maltreatment. Consistent with a cumulative stressors model of children's adaptation, individual strengths distinguished resilient from non-resilient children under conditions of low, but not high, family and neighborhood stress. CONCLUSION: These findings suggest that for children residing in multi-problem families, personal resources may not be sufficient to promote their adaptive functioning. 相似文献

挥发性有机物(VOCs)的污染与控制技术日益受到重视。近年来发展起来的非平衡等离子体技术在治理VOCs方面已初步显示其独特的技术优势,现已成为废气治理研究领域中的前沿热点课题之一。等离子体法降解VOCs的机理较为复杂,研究不同线路对VOCs降解过程的影响意义重大。采用脉冲电晕放电等离子体技术,建立了混合电晕、有机电晕、空气电晕和分别电晕4种不同的实验方案,选取苯为代表物质进行实验研究,在初始浓度、停留时间和电源参数等一定的条件下,考察脉冲电压对苯去除率的影响。结果表明,电压为140kV、混合电晕时苯的去除率达到82.73%,脉冲电晕技术处理低浓度有机废气效果较好。 相似文献

Research‐practice partnerships offer counselor educators an opportunity to generate scholarship that can promote client welfare and create systemic change in practice and policy. The purpose of this article is to articulate strategies for building and sustaining research‐practice partnerships, as well as suggest methods for evaluating these partnerships. 相似文献

The federal definition of emotional disturbance (ED) has been heavily criticized as vaguely defined and poorly operationalized yet there has not been a formal analysis of the reliability of the ED criteria. This study examined the reliability of the federal criteria for a special education designation of ED. A total of 179 school psychologists reviewed a mock special education report, made an eligibility determination, and provided information about their eligibility decision. In all, 56 participants found the student met ED eligibility criteria using 16 different combinations of the five criteria. Krippendorff’s α, a statistic preferred for content analysis, was calculated as a measure of criterion reliability. Results indicated extremely poor reliability (α = 0.2011). These findings demonstrate the importance of redefining the existing criteria. 相似文献
