Relative shank to thigh length is associated with different mechanisms of power production during elite male ergometer rowing

The effect of anthropometric differences in shank to thigh length ratio upon timing and magnitude of joint power production during the drive phase of the rowing stroke was investigated in 14 elite male rowers. Rowers were tested on the RowPerfect ergometer which was instrumented at the handle and foot stretcher to measure force generation, and a nine segment inverse dynamics model used to calculate the rower's joint and overall power production. Rowers were divided into two groups according to relative shank thigh ratio. Time to half lumbar power generation was significantly earlier in shorter shank rowers (p = 0.028) compared to longer shank rowers, who showed no lumbar power generation during the same period of the drive phase. Rowers with a relatively shorter shank demonstrated earlier lumbar power generation during the drive phase resulting from restricted rotation of the pelvic segment requiring increased lumbar extension in these rowers. Earlier lumbar power generation and extension did not appear to directly affect performance measures of the short shank group, and so can be attributed to a technical adaptation developed to maximise rowing performance.  相似文献

Intercollegiate Athletes and Effective Educational Practices: Winning Combination or Losing Effort?     

Paul D. Umbach  Megan M. Palmer  George D. Kuh  Stephanie J. Hannah 《Research in higher education》2006,47(6):709-733

Scrutiny of intercollegiate athletics has intensified in recent years. This study compares student-athletes with those of non-athletes in terms of their engagement in effective educational practices. Contrary to many reports in the popular media, the findings from this study indicate that, on balance, student-athletes across a large number of colleges and universities do not differ greatly from their peers in terms of their participation in effective educational practices. In most instances, when differences do exist, they favor athletes.  相似文献   

Social anxiety in learning: stages of change in a sample of UK undergraduates     

Phil Topham  Naomi Moller  Hannah Davies 《Journal of Further & Higher Education》2016,40(1):125-145

Social anxiety in learning is prevalent amongst traditional-age students and has a marked effect on their engagement with higher education. It receives little attention from academic or support services and there is a presumption that students will manage their anxieties. Yet it is unclear what psychosocial resources they might bring to this task and how these may develop through the undergraduate years. This study sought to identify possible change processes in student social anxiety by analysing qualitative responses obtained from Level 2 undergraduate students (n=39) in relation to their experience of learning situations such as lectures, seminars and group presentations. Thematic analysis suggested a four-stage developmental progression for students in terms of their experience and orientation to coping with social anxiety. Implications for staff development and student support are outlined.  相似文献

The impact of an online intervention (Brainology) on the mindset and resiliency of secondary school pupils: a preliminary mixed methods study     

Claire Donohoe  Keith Topping  Elizabeth Hannah 《教育心理学》2012,32(5):641-655

This preliminary study investigated the impact of the online interactive programme Brainology (which aimed to encourage a growth mindset) on the mindset, resiliency and sense of mastery of secondary school pupils. A quasi-experimental pre-, post- and follow-up mixed-methods study was carried out with 33 participants aged 13–14?years. The measures were Dweck’s theories of intelligence scale and Prince-Embury’s resiliency scales for children and adolescents. Quantitative data were analysed using analysis of variance. Qualitative data from focus groups were categorised and coded. The programme led to a significant increase in pre- to post-mindset scores for the intervention group. However, there was a significant decline at follow-up and the initial impact of the intervention was not sustained. There were no significant changes in mindset for the comparison group. There were no significant changes in resiliency or sense of mastery for either group. The significant short-term impact of Brainology and non-significant follow-up findings are discussed. The present study has limitations such as small sample size, which has implications for generalisability. Future research should investigate the longer term effectiveness of educational interventions in schools.

"I was born full deaf." Written language outcomes after 1 year of strategic and interactive writing instruction     

Wolbers KA  Dostal HM  Bowers LM 《Journal of deaf studies and deaf education》2012,17(1):19-38

Nonstandard grammatical forms are often present in the writing of deaf students that are rarely, if ever, seen in the writing of hearing students. With the implementation of Strategic and Interactive Writing Instruction (SIWI) in previous studies, students have demonstrated significant gains in high-level writing skills (e.g., text structure) but have also made gains with English grammar skills. This 1-year study expands on prior research by longitudinally examining the written language growth (i.e., writing length, sentence complexity, sentence awareness, and function words) of 29 deaf middle-school students. A repeated-measures analysis of variance with a between-subjects variable for literacy achievement level was used to examine gains over time and the intervention's efficacy when used with students of various literacy levels. Students, whether high or low achieving, demonstrated statistically significant gains with writing length, sentence complexity, and sentence awareness. Subordinate clauses were found to be an area of difficulty, and follow up strategies are suggested. An analysis of function word data, specifically prepositions and articles, revealed different patterns of written language growth by language group (e.g., American Sign Language users, oral students, users of English-based sign).  相似文献

Library project management in a collaborative web-based working environment     

Tracey Stanley  Frances Norton  Barry Dickson 《New Review of Academic Librarianship》2013,19(1):70-83

This paper discusses the emerging paradigm of project management performed in a web-based working environment. It highlights how project management and its associated features are strongly linked to fulfilling quality and value criteria for customers, and it examines how collaborative working environments can greatly reduce the administrative burden of managing large projects, especially and almost paradoxically, when resources are limited. Specifically, the paper examines the application of a project management methodology (PRINCE2) together with the use of a collaborative web-based working environment over a number of pilot projects at Leeds University Library. It describes the pilot phase of a library management decision to run a series of major Library projects using project management methodology, while continuing to run other projects through the existing locally developed planning mechanisms and describes the pitfalls of these latter alternatives, less sophisticated project management tools, and describes the main issues that this change in practice has brought to light. It draws preliminary conclusions about the effectiveness of this change in practice in one of the UK's largest academic libraries.  相似文献
