Duchenne Muscular Dystrophy (DMD) is a neurogenetic developmental disorder that presents with progressive muscular weakness. It is caused by a mutation in a gene that results in the absence of specific products that normally localize to muscle cells and the central nervous system (CNS). The majority of affected individuals have IQs within the normal range, generally with lower verbal than performance IQ scores. Prior work has demonstrated selective deficits on tests of verbal span and immediate memory. For the current study, 26 boys with DMD (and normal intellectual function) and their unaffected siblings were evaluated. Paired comparisons demonstrated that the children with DMD had significantly poorer academic achievement scores than their siblings, even though their vocabulary levels and home and educational environments were comparable. Children with DMD also had more behavioral concerns, physical disabilities, and poorer verbal memory spans. Linear regression indicated that behavioral concerns, executive function, and physical disability did not contribute substantially to academic performance, whereas performance on verbal span did. DMD presents with a selective developmental aberration in verbal span that has wide‐ranging consequences on learning skills. 相似文献

中外文学史上关于主仆之恋这一爱情模式大都以悲剧结局,这种悲剧属于社会悲剧。文章通过对《家》中觉慧与鸣凤、《呼啸山庄》中希刺克利夫与凯瑟琳这两对艺术形象的比较,分析产生他们爱情悲剧的根源及各自不同的爱情表现形态。在不同的社会制度中,东方的专制主义压制人的个性发展,而西方资本主义制度使人性扭曲,人的道德沦丧。 相似文献

Response to intervention (RTI) is advocated in elementary school as a system‐wide, multitiered model of academic and behavioral interventions. Middle schools have begun adopting RTI models based on these existing elementary models. This investigation into current middle school RTI practices describes technical aspects as well as some of cultural and contextual issues surrounding implementation. The study included multiple data collection procedures including surveys, discussion groups, phone interviews, and site visits. Although many schools reported substantial progress with implementation, they recognized rigorous implementation of RTI posed such on‐going challenges as changes in staffing, curricular realignments, very limited selections of screening and progress monitoring tools aligned with their curriculum, and scheduling of secondary and tertiary level interventions. 相似文献

Investing in on-the-job training (OJT) is risky because the value of specific human capital is lost if a permanent separation occurs between the employer and employee. An efficient contract between the two parties can reduce but not eliminate the risk. In theory, some form of “training insurance” could further reduce the risk or eliminate it entirely by pooling risk among employees or employers. The merits of this idea in practice could be determined by field tests, as could the value of ideas for improving the actual process of OJT. 相似文献
