String tension effects on tennis ball rebound speed and accuracy during playing conditions     

Bower R  Cross R 《Journal of sports sciences》2005,23(7):765-771

The primary aim of this study was to determine whether variations in rebound speed and accuracy of a tennis ball could be detected during game-simulated conditions when using three rackets strung with three string tensions. Tennis balls were projected from a ball machine towards participants who attempted to stroke the ball cross-court into the opposing singles court. The rebound speed of each impact was measured using a radar gun located behind the baseline of the court. An observer also recorded the number of balls landing in, long, wide and in the net. It was found that rebound speeds for males (110.1+/-10.2 km.h-1; mean+/-s) were slightly higher than those of females (103.6+/-8.6 km.h-1; P<0.05) and that low string tensions (180 N) produced greater rebound speeds (108.1+/-9.9 km.h-1) than high string tensions (280 N, 105.3+/-9.6 km.h-1; P<0.05). This finding is in line with laboratory results and theoretical predictions of other researchers. With respect to accuracy, the type of error made was significantly influenced by the string tension (P<0.05). This was particularly evident when considering whether the ball travelled long or landed in the net. High string tension was more likely to result in a net error, whereas low string tension was more likely to result in the ball travelling long. It was concluded that both gender and the string tension influence the speed and accuracy of the tennis ball.  相似文献

Mixed-method pre-cooling reduces physiological demand without improving performance of medium-fast bowling in the heat     

Minett GM  Duffield R  Kellett A  Portus M 《Journal of sports sciences》2012,30(9):907-915

This study examined physiological and performance effects of pre-cooling on medium-fast bowling in the heat. Ten, medium-fast bowlers completed two randomised trials involving either cooling (mixed-methods) or control (no cooling) interventions before a 6-over bowling spell in 31.9±2.1°C and 63.5±9.3% relative humidity. Measures included bowling performance (ball speed, accuracy and run-up speeds), physical characteristics (global positioning system monitoring and counter-movement jump height), physiological (heart rate, core temperature, skin temperature and sweat loss), biochemical (serum concentrations of damage, stress and inflammation) and perceptual variables (perceived exertion and thermal sensation). Mean ball speed (114.5±7.1 vs. 114.1±7.2 km · h(-1); P = 0.63; d = 0.09), accuracy (43.1±10.6 vs. 44.2±12.5 AU; P = 0.76; d = 0.14) and total run-up speed (19.1±4.1 vs. 19.3±3.8 km · h(-1); P = 0.66; d = 0.06) did not differ between pre-cooling and control respectively; however 20-m sprint speed between overs was 5.9±7.3% greater at Over 4 after pre-cooling (P = 0.03; d = 0.75). Pre-cooling reduced skin temperature after the intervention period (P = 0.006; d = 2.28), core temperature and pre-over heart rates throughout (P = 0.01-0.04; d = 0.96-1.74) and sweat loss by 0.4±0.3 kg (P = 0.01; d = 0.34). Mean rating of perceived exertion and thermal sensation were lower during pre-cooling trials (P = 0.004-0.03; d = 0.77-3.13). Despite no observed improvement in bowling performance, pre-cooling maintained between-over sprint speeds and blunted physiological and perceptual demands to ease the thermoregulatory demands of medium-fast bowling in hot conditions.  相似文献   

Sustainability transitions: An emerging field of research and its prospects   总被引：4，自引：1，他引：3  

Jochen Markard  Rob RavenBernhard Truffer 《Research Policy》2012,41(6):955-967

Sustainability oriented innovation and technology studies have received increasing attention over the past 10-15 years. In particular, a new field dealing with “sustainability transitions” has gained ground and reached an output of 60-100 academic papers per year. In this article, we aim to identify the intellectual contours of this emerging field by conducting a review of basic conceptual frameworks, together with bibliographical analysis of 540 journal articles in the field. It is against this background that we position the six papers assembled in a special section in Research Policy. These papers pave the way for new conceptual developments and serve as stepping-stones in the maturation of sustainability transition studies, by linking with the scholarly literatures of management studies, sociology, policy studies, economic geography, and modeling.  相似文献   

Middle‐class struggle? Identity‐work and leisure among sixth formers in the United Kingdom     

Mary Jane Kehily  Rob Pattman 《British Journal of Sociology of Education》2006,27(1):37-52

This paper explores the ways in which sixth‐form students in Milton Keynes negotiate their identities and the symbolic significance they attach to leisure activities in the process of doing this. The paper draws upon qualitative, young‐person‐centred interviews with sixth formers in state and private schools. We address the investments of sixth formers in constructing themselves as autonomous individuals and argue that they do so from a position of middle‐class subjects‐in‐the‐making. Through an inversion of Willis’ (1977 Willis, P. 1977. Learning to labour, Aldershot: Gower.  [Google Scholar]) (focus, our concern is to make explicit the implicitly middle‐class identities sixth formers were forging. We argue that the identity‐work of sixth formers plays a part in the reproduction of school‐based class inequalities by pathologising working‐class students while constructing themselves as bourgeois liberal individuals.  相似文献   

Oral Communication Skills in Higher Education: Using a Performance-Based Evaluation Rubric to Assess Communication Skills   总被引：1，自引：0，他引：1  

Norah E. Dunbar  Catherine F. Brooks  Tara Kubicka-Miller 《Innovative Higher Education》2006,31(2):115-128

This study used The Competent Speaker, a rubric developed by the National Communication Association (S. P. Morreale, M. R. Moore, K. P. Taylor, D. Surges-Tatum, & R. Hulbert-Johnson, 1993), to evaluate student performance in general education public speaking courses as a case study of student skills and programmatic assessment. Results indicate that students taking the general education public speaking course are below satisfactory standards on five of the eight competencies defined by the National Communication Association and are above satisfactory standards on two of the eight competencies. Implications for this particular program, other communication departments, and communication across the curriculum in general education are discussed. We also offer suggestions for those in other disciplines or educational settings in the use of performance evaluation rubrics for assessing other student skills/knowledge and for training new teachers.

Quality Control in Education: — The Span of Control Controversy ‐Some Practical Considerations     

Glyn Rawlins  Rob Sindall 《School Leadership & Management》2013,33(2):95-100

This article gives the background to the introduction of a statutory system of staff appraisal in schools in England. It explains and provides insights into the various stages of the appraisal process from a management perspective. It begins from the premise that a manager is responsible for the performance of staff which he or she manages. Finally, it discusses a number of issues which are problematic and which need to be resolved if a staff appraisal scheme is to be successful from both the individual's and the school's viewpoints.  相似文献
