Sources of support and psychological distress among academically successful inner-city youth

Study 1 examined the relationships between parental attachment, academic achievement, and psychological distress among a multiethnic sample of academically successful inner-city high school students (19 White, 54 Black, 9 Asian, 18 Hispanic). These students participated in an enrichment program designed to prepare high school students for college success. The results suggest that the affective quality of maternal attachment is positively associated with grade point average, and the affective quality of paternal attachment is negatively associated with depressive symptoms. In Study 2, case examples provide an examination of sources of support, life stress, and patterns of resilience. Implications for prevention and intervention are also discussed.     

Paper and voice MAYSI-2: format comparability and concordance with the voice DISC-IV

The authors examine the comparability of paper and voice formats of the Massachusetts Youth Screening Instrument-Second Version (MAYSI-2) as well as each format's concordance with the Voice Diagnostic Interview Schedule for Children (DISC) among adjudicated youth. Comparability is assessed among 248 youths admitted to a South Carolina Assessment Center. Mean scores and alpha coefficients are calculated, and area under the curve and positive and negative predictive values are used to compare concordance to the DISC. Paper and voice formats are significantly correlated, have similar alpha coefficients, and have comparable concordance with the DISC, suggesting that the MAYSI-2 paper and voice formats are comparable instruments. The voice format may be preferable to the paper format for screening justice youth for mental health problems because it may reduce incomplete data and increase reporting of stigmatized behaviors and because of its ability to automatically generate scored reports and aggregate data.     

Parents Explain More Often to Boys than to Girls During Shared Scientific Thinking

Young children's everyday scientific thinking often occurs in the context of parent-child interactions. In a study of naturally occurring family conversation, parents were three times more likely to explain science to boys than to girls while using interactive science exhibits in a museum. This difference in explanation occurred despite the fact that parents were equally likely to talk to their male and female children about how to use the exhibits and about the evidence generated by the exhibits. The findings suggest that parents engaged in informal science activities with their children may be unintentionally contributing to a gender gap in children's scientific literacy well before children encounter formal science instruction in grade school.     

鲍德里亚对马克思生产概念的误读

鲍德里亚对马克思生产概念的批评主要有以下三个方面:一、马克思没能看到使用价值也是由交换价值生产出来的,因而他满足于用以生产为基础的政治经济学模式来完成对资本的批判;二、由于他使用的是“人体解剖对于猴体解剖是一把钥匙”的方法论,因而,他对前资本主义社会发展史的分析也是错误的;三、由上述两点决定了他对未来革命的路径的判断也是错误的。文章认为,鲍德里亚在理解马克思的使用价值、交换价值等概念时,根本没有进入这些概念在马克思那里的历史发生学视域,因而不仅导致了他对马克思生产概念之本质的误判,而且还导致了他对马克思的社会历史观的误读。至于鲍德里亚在资本对生活世界的统治模式以及未来革命路径等问题上的观点,则明显地具有方法论上的缺陷。     

病前智力估计:效度与局限

病前智力的估计是甄别、诊断智能衰退的必要条件,有重要的临床和科研意义。依据学业成绩和工作成就等背景资料可综合评估病前智力的水平与结构,但其定性的结论不利于科研,且难免主观。依赖人口统计学变量的回归公式能客观给出确切的、具有一定效度的估计数,但会高估或低估极端智商。依据当前测验成绩的估计有“保持”和最佳作业两种模式,这种估计个体特异高,但被试在选用测验上的当前表现能否代表病前智力水平尚有争议。联合不同方法能提高预测效度。
