This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R² values of >0.85 for all variables excluding deadlift mean velocity (R² = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.  相似文献

面向情境兴趣的文本信息过滤系统   总被引：3，自引：0，他引：3  

宗胜  徐博艺 《情报科学》2007,25(7):1085-1088

随着对信息过滤技术研究的深入和展开，信息过滤系统的推荐质量不断得到提高。但长期以来文本信息过滤系统都是用来推荐符合用户长期兴趣的信息，而忽略了用户对短期突发信息的需求。针对这种情况，本文提出了面向个人情境兴趣的文本信息过滤系统。模拟实验显示，这种过滤系统可以更好的适用用户信息需求快速变化的情况。  相似文献

Driving change from ‘the middle’: middle leading for site based educational development     

Christine Edwards-Groves  Peter Grootenboer  Ian Hardy  Karin Rönnerman 《School Leadership & Management》2019,39(3-4):315-333

ABSTRACT

Educational researchers have invested much in isolating the specific ‘drivers’ that influence school change and teacher professional development. In this vein, this article draws attention to necessarily situated understandings of practice development through research into the nature of ‘middle leading’ for site based education development in one primary school district in regional Australia. Drawing on practice theory, the analysis reveals how developing and sustaining change in schools is contingent on middle leaders’ insider knowledge, shared responsibility and capacity to sustain and ‘drive’ teachers’ learning. The article argues more situated understandings of middle leading practices are essential for sustainable educational reform.  相似文献

With increasing specialization, most academic disciplines have become highly compartmentalized. Numerous organizations in higher education strongly encourage interdisciplinary collaboration at the faculty and student level. The purposes of this article are (a) to provide a conceptual framework for explaining how and why an interdisciplinary case study method is a catalyst for the development of students and faculty; (b) to document the conception, planning, organizing, and results of an interdisciplinary case study workshop; and (c) to provide recommendations to encouragechange others who might want to apply this model to their own interdisciplinary efforts.All authors are at Towson University Sharon B. Buchbinder, R.N., PhD, is associate professor of health science. She received her PhD from the University of Illinois at Chicago. Special interests are physician job satisfaction and turnover, patient compliance, learning styles and teamwork among undergraduates. Patricia M.
