Abstract This study investigated the association between explosive force production during isometric squats and athletic performance (sprint time and countermovement jump height). Sprint time (5 and 20 m) and jump height were recorded in 18 male elite-standard varsity rugby union players. Participants also completed a series of maximal- and explosive-isometric squats to measure maximal force and explosive force at 50-ms intervals up to 250 ms from force onset. Sprint performance was related to early phase (≤100 ms) explosive force normalised to maximal force (5 m, r = ?0.63, P = 0.005; and 20 m, r = ?0.54, P = 0.020), but jump height was related to later phase (>100 ms) absolute explosive force (0.51 < r < 0.61; 0.006 < P < 0.035). When participants were separated for 5-m sprint time (< or ≥ 1s), the faster group had greater normalised explosive force in the first 150 ms of explosive-isometric squats (33–67%; 0.001 < P < 0.017). The results suggest that explosive force production during isometric squats was associated with athletic performance. Specifically, sprint performance was most strongly related to the proportion of maximal force achieved in the initial phase of explosive-isometric squats, whilst jump height was most strongly related to absolute force in the later phase of the explosive-isometric squats. 相似文献

This paper shows that minimizing a quadratic cost function is not particularly useful for selecting a small number of controller gains in vehicle headway control. For cases in which a large number of controller gains are to be selected, the quadratic cost function may be useful, but the weighting parameter values cannot usually be chosen a priori if transient performance measures are of a particular interest. Examples illustrate how values of weights in a simplified cost function can be selected to yield acceptable transient performance. This performance is compared with that for a system containing only a few gains and optimized without recourse to a cost function. 相似文献

A qualitative study was conducted to explore supervisors' experiences of supervisee incompatibility in triadic supervision. In‐depth interviews were completed with 9 doctoral student supervisors in a counselor education program, and a whole‐text analysis generated 3 categories. Supervisee incompatibility took a wide variety of forms and negatively affected the content of supervision, including its progress and productivity. It also negatively influenced the process of supervision, including the feedback and support offered by either the supervisor or the supervisees and the general atmosphere of supervision meetings. Implications of the findings for counseling supervision and for further research are also addressed. 相似文献

Understanding the determinants of PhD student satisfaction is likely to become increasingly vital for universities as student satisfaction rankings already ubiquitous at undergraduate and master degree levels extend more broadly to the PhD level. Moreover, as PhD student populations and university competition become increasingly transnational, there is a growing need to understand cross-nationally common determinants of satisfaction. Building on prior research into PhD student satisfaction, and drawing upon relevant conceptual and metrical refinements in the measurement of satisfaction from cognate domains of psychology, we use cross-sectional data (N?=?409) from PhD candidates across the sciences, social sciences and humanities in 63 universities from 20 countries to examine how overall PhD student satisfaction is determined by, respectively and in combination, supervisor, department and peer-group, in terms of both their academic qualities and supportiveness. Taken together, we find that supervisor supportiveness is the greatest predictor of PhD student satisfaction, but that supervisor academic qualities have no significant effect. However, both the academic qualities and supportiveness of departments significantly predict PhD student satisfaction, suggesting university departments and PhD supervisors would ideally work jointly, and perhaps more closely than many currently do, to achieve competitive levels of PhD student satisfaction. 相似文献

As universities transform into enterprises, academics are facing new challenges, especially in their teaching. This is because of the demands for student‐centred programmes that offer more flexibility, the use of Course Management Systems such as Blackboard, and the expectation that instructors will perform (more) efficiently and effectively. In this research, the focus is on teaching‐related activities to support instructors to stay in control, given these increasing pressures. A Personal Performance Model that shows key aspects of academics’ performance relating to teaching tasks was developed. A series of studies relating to gaps between expected and actual performance was carried out using the Human Performance Technology methodology. As an intervention based on these gaps, a Personal Performance Support Tool was developed to support instructors with their time and task management in relation to teaching, as well as to develop an elaborated insight on how to support instructors as they respond to changing expectations for their teaching performance. Key steps to guide universities in implementing such a support tool have been identified as a result of the research. 相似文献

Academics or entrepreneurs? Investigating role identity modification of university scientists involved in commercialization activity 总被引:3,自引:0,他引:3
Establishing the microfoundations of academic entrepreneurship requires closer scrutiny of a key actor contributing to this phenomenon—the university scientist. We investigate the sense-making that scientists engage in as part of their participation in technology transfer and postulate that this process involves a potential modification in their role identity. We analyzed more than 70 h of interview data at a premier U.S. public research university. We observe that scientists invoke rationales for involvement that are congruent with their academic role identity. They typically adopt a hybrid role identity that comprises a focal academic self and a secondary commercial persona. We delineate two mechanisms – delegating and buffering – that these individuals deploy to facilitate such salience in their hybrid role identity. Overall, these patterns suggest that university scientists take active steps to preserve their academic role identity even as they participate in technology transfer. Our findings clarify the social psychological processes underlying scientist involvement in commercialization activity, and offer fresh insights to the academic entrepreneurship, science policy and role identity literatures. 相似文献
