The first purpose of this study was to examine the interrelationships among three forms of relational efficacy within performing dyads, namely, self-efficacy, other-efficacy, and relation-inferred self-efficacy. The second objective was to examine the relationships between these efficacy beliefs and athletes' perceptions of their commitment to and satisfaction with their current partnership. Participants were 120 junior tennis players (age, M = 14.30 years, SD = 1.21) performing within 60 intact pairs (i.e., doubles). Results revealed that self-efficacy and other-efficacy were predictive of athlete commitment and satisfaction, respectively. In addition, by utilizing actor-partner interdependence models, partner as well as actor effects were evident. The findings illustrate that relational efficacy beliefs may not only have implications for the individual holding such beliefs, but also for his or her relational partner. Implications for the future study of efficacy beliefs within dyadic contexts are discussed.  相似文献

The control of human limb movement has been the focus of research for more than a century. A major issue to emerge from this work is the manner in which the central nervous system regulates electromyographic (EMG) activity to produce movements that differ in distance, velocity, and movement time. However the different methods of analysis often used to analyze EMG data could result in different kinematic-EMG relationships. In this study, participants performed an elbow flexion task to one of five distance goals (between 5 degrees and 50 degrees) using three movement speeds. EMG data from the right elbow flexors were compared using a trial-by-trial analysis and one based on averaged data. Averaging across trials underestimated biceps EMG amplitude at all movement distances and speeds compared to a trial-by-trial analysis. Averaging overestimated EMG burst duration compared to the trial-by-trial analysis. Peak agonist EMG amplitude was positively related to distance and inversely related to movement time. Agonist EMG duration was constant for movement distances less than 30 degrees but increased in the 50 degrees condition. The results support the view that peak EMG amplitude and duration can be controlled independently, but EMG duration changes only for longer distance movements when additional force is required.  相似文献

Although many professions practice some type of formal peer review, similar support for increasing the quality and efficiency of instructional design products is largely informal. Most designers develop solutions in professional eommunilies-of-practice, but formal design methodologies ordained by many corporations and instructional design schools do not account for the strong influence these communities have on design decisions. This paper describes an instructional design review process that is modeled after a widely accepted practice among software developers in which peers offer feedback through “structured walkthroughs.” The instructional design review helps the practitioner develop stronger designs more quickly. provides a means to scaffold the novice designer in the vagaries of the workplace, and improves organizational memory. An artifact of a design review as well as guidelines and success factors are presented. The paper provides a summary of a formal peer review structure that has been developed and tested over the past three years at a major corporation.  相似文献

本文运用固定效应模型,分析近十年美国公立世界一流大学的经费支出数据。研究发现:美国一流公立大学中教学科研经费是主要支出;经费总支出与一流大学的排名没有显著相关性,但部分经费支出对大学排名有显著影响。对于无医院服务支出的高校,公共服务支出与大学排名显著正相关;对于有医院服务支出的高校,辅助经营支出的增加有助于大学排名的提升,公共服务支出的影响却相反。因此,提高经费使用效率比增加总额更为重要。我国“双一流”建设高校应该革新经费支出配置理念,建立科学有效的经费配置体系,增大学校各类服务支出。  相似文献
