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

Mergers and acquisitions: Their effect on the innovative performance of companies in high-tech industries 总被引:6,自引:0,他引:6
This study examines the post-M&A innovative performance of acquiring firms in four major high-tech sectors. Non-technological M&As appear to have a negative impact on the acquiring firm's post-M&A innovative performance. With respect to technological M&As, a large relative size of the acquired knowledge base reduces the innovative performance of the acquiring firm. The absolute size of the acquired knowledge base only has a positive effect during the first couple of years after which the effect turns around and we see a negative effect on the innovative performance of the acquiring firm. The relatedness between the acquired and acquiring firms’ knowledge bases has a curvilinear impact on the acquiring firm's innovative performance. This indicates that companies should target M&A ‘partners’ that are neither too unrelated nor too similar in terms of their knowledge base. 相似文献

Measuring innovative performance: is there an advantage in using multiple indicators? 总被引:10,自引:0,他引:10
The innovative performance of companies has been studied quite extensively and for a long period of time. However, the results of many studies have not yet led to a generally accepted indicator of innovative performance or a common set of indicators. So far the variety in terms of constructs, measurements, samples, industries and countries has been substantial. This paper studies the innovative performance of a large international sample of nearly 1200 companies in four high-tech industries, using a variety of indicators. These indicators range from R&D inputs, patent counts and patent citations to new product announcements. The study establishes that a composite construct based on these four indicators clearly catches a latent variable ‘innovative performance’. However, our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high-tech industries. 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

The Master of Science in engineering technology: biochemical engineering is organised in KU Leuven at four geographically dispersed campuses. To sustain the Master's programmes at all campuses, it is clear that a unique education profile at each campus is crucial. In addition, a rationalisation is required by increased cooperation, increased exchange of lecturers, and increased student mobility. To achieve this, a multicampus education system for the M.Sc. in engineering technology: biochemical engineering was developed by offering modules that are also available for students of other campuses. Such a module is primarily based on the research expertise present at the campus. In the development, special attention has been given to the optimal organisation of the modules, evaluation, required modifications of the current curricula, and the practical consequences for students following the module at another campus. Even in the first year of implementation, around 30% of the students followed a multicampus module, which indicates the potential success of the multicampus concept described here. 相似文献
