The authors explore the competitive advantage of the U.S. film industry in the world market in light of current trends in revenue streams, exhibition outlets, costs, and changes in production, distribution, marketing, and promotion. The article discusses key legal and trade concerns, and the film markets in selected regions and countries in relation to their impact on the future performance of the U.S. film industry abroad. 相似文献

In line with the current interest in alternative and authentic assessment, this study focused on the evaluation of students' performance on science laboratory process skills. A sample of 147 year 5 students from six schools responded to laboratory process skills tests which assess investigating, performing and reasoning in the content areas of biology, chemistry and physics. The data were analysed to provide information about students' overall practical performance and to identify specific preinstructional conceptions and erros. An investigation of predictors of laboratory performance revealed significant associations between performance and amount of homework done and students' perceptions of several aspects of the classroom environment (personalisation, investigation and organisation). The gender differences commonly found in science achievement were absent when laboratory performance was used as the criterion. 相似文献

We examined the effects of time of day on a cycling time trial with and without a prolonged warm-up, among cyclists who tended towards being high in \"morningness\". Eight male cyclists (mean +/- s: age = 24.9 +/- 3.5 years, peak power output = 319 +/- 34 W, chronotype = 39 +/- 6 units) completed a 16.1-km time trial without a substantial warm-up at both 07:30 and 17:30 h. The time trial was also completed at both times of day after a 25-min warm-up at 60% of peak power. Power output, heart rate, intra-aural temperature and category ratings of perceived exertion (CR-10) were measured throughout the time trial. Post-test blood lactate concentration was also recorded. Warm-up generally improved time trial performance at both times of day (95% CI for improvement = 0 to 30 s), but mean cycling time was still significantly slower at 07:30 h than at 17:30 h after the warm-up (95% CI for difference = 33 to 66 s). Intra-aural temperature increased as the time trial progressed (P < 0.0005) and was significantly higher throughout the time trials at 17:30 h (P = 0.001), irrespective of whether the cyclists performed a warm-up or not. Blood lactate concentration after the time trial was lowest at 07:30 h without a warm-up (P = 0.02). No effects of time of day or warm-up were found for CR-10 or heart rate responses during the time trial. These results suggest that 16.1-km cycling performance is worse in the morning than in the afternoon, even with athletes who tend towards 'morningness', and who perform a vigorous 25-min warm-up. Diurnal variation in cycling performance is, therefore, relatively robust to some external and behavioural factors. 相似文献

Examined the relations of parent and child behaviors with children's perceptions of their academic competence. 74 high-achieving third-grade children, with varying levels of perceived academic competence, were observed working with mothers and fathers both on solvable tasks (Period 1) and during a period that included some unsolvable tasks (Period 2). Results indicated that children's perceived academic competence was positively related to father warmth, both at Period 1 and at Period 2. Children's perceived academic competence was also positively related to their own behavior when working with fathers at Period 2. Specifically, children with higher perceived academic competence showed more emotional restraint and were more self-reliant when working on tasks at Period 2 than were children with lower perceived academic competence. The results indicate that there are systematic, observable correlates of children's self-reports of their perceived academic competence. 相似文献

The present study filled some gaps in past learning environment research in that, first, it involved the development of a new instrument tailor-made specifically for use in computer-assisted learning (CAL) classrooms and, second, it provided one of the rare examples of an evaluation of computer-assisted learning based on its impact on the nature of a classroom learning environment as perceived by students. In addition, the research was conducted in the unique milieu of the Singapore school system, and it investigated associations between students' outcomes and the classroom environment in computer-assisted learning settings. 相似文献
