Validity of an upper-body-mounted accelerometer to measure peak vertical and resultant force during running and change-of-direction tasks     

Daniel W.T. Wundersitz  Kevin J. Netto  Brad Aisbett  Paul B. Gastin 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(4):403-412

This study assessed the validity of a tri-axial accelerometer worn on the upper body to estimate peak forces during running and change-of-direction tasks. Seventeen participants completed four different running and change-of-direction tasks (0°, 45°, 90°, and 180°; five trials per condition). Peak crania-caudal and resultant acceleration was converted to force and compared against peak force plate ground reaction force (GRF) in two formats (raw and smoothed). The resultant smoothed (10 Hz) and crania-caudal raw (except 180°) accelerometer values were not significantly different to resultant and vertical GRF for all running and change-of-direction tasks, respectively. Resultant accelerometer measures showed no to strong significant correlations (r = 0.00–0.76) and moderate to large measurement errors (coefficient of variation [CV] = 11.7–23.9%). Crania-caudal accelerometer measures showed small to moderate correlations (r = ? 0.26 to 0.39) and moderate to large measurement errors (CV = 15.0–20.6%). Accelerometers, within integrated micro-technology tracking devices and worn on the upper body, can provide a relative measure of peak impact force experienced during running and two change-of-direction tasks (45° and 90°) provided that resultant smoothed values are used.  相似文献   

Examining proximal and distal influences on the part-time student experience through an ecological systems theory     

Mike McLinden 《Teaching in Higher Education》2017,22(3):373-388

This conceptual paper contributes to the literature base on promoting equality of opportunity for students in higher education through seeking to broaden understanding of the influences on part-time study in the United Kingdom (UK). These students constitute a significant proportion of the total student population in the UK with research highlighting particular issues they encounter in their learning experience. An analysis of these issues suggests multiple sources of influence within a complex higher education landscape. Bronfenbrenner’s ecological systems theory is drawn upon as a lens through which to examine proximal and distal influences on part-time students and their study experiences in higher education and to propose a research design to facilitate future participation. The paper has significance for educators and researchers concerned with developing understanding of the multilayered influences on participation in higher education in a rapidly changing educational landscape in order to ensure equality of opportunity for all students.  相似文献   

机床主轴的动刚性评估     

崔勇俊 《大连大学学报》2003,24(2):12-15

本文提出了一种评估机床主轴的动刚性的一种新方法,此方法以机床主轴的固有频率为基础,在安装在机床主轴上的实验棒的半径方向上加振动脉冲,测出其固有频率,然后用固有频率算出主轴的刚度,另外对被测的机床又进行了主铣刀切削实验,得出了表面粗糙度与刚度的相关性.  相似文献   

Funding, resource allocation, and performance in higher education systems   总被引：4，自引：0，他引：4  

Ingo Liefner 《Higher Education》2003,46(4):469-489

This article analyzes forms of resourceallocation in university systems and theireffects on performance in institutions ofhigher education. Internationally, highereducation systems differ substantially withregard to research and education fundingsources and to ways that resources areallocated. European universities receive themajority of their funding from public sources,but private funding plays a more important rolein Anglo-American systems of higher education.Many governments use competitive elements inthe process of allocating public funds toinstitutions of higher education. Examplesinclude the implementation of performancemeasures through formula funding, or resourceallocation on the basis of evaluated projectproposals. Corresponding forms ofperformance-based resource allocation can befound within most higher educationinstitutions. This article analyzes how variousforms of funding and resource allocation affectuniversities at the macro-level and individualbehavior at the micro-level. A theoreticalapproach to this problem suggests thatperformance-based funding tends to bring aboutpositive changes but is also a factor inunintended side effects. Forms of resourceallocation influence the behavior of academicsand managers in higher education, particularlytheir levels of activity as well as the kindsof activities they engage in and their ways ofdealing with risks. Empirical analyses partlyconfirm these hypotheses. It can be shown thatchanges in resource allocation have an impacton the level and type of activity academicsconcentrate on but not on the long-term successof universities.  相似文献   

基于EPG的蒙古语塞音、塞擦音研究     

呼和 《内蒙古大学学报(人文社会科学版)》2005,37(3):17-24

塞音、塞擦音的生理长度远远长于其声学长度。在总长度方面虽然没有明显的差别，但不送气音一般都比相应的送气音长。词首塞音和塞擦音都比相应的词尾塞音和塞擦音长。塞音和塞擦音在长度排列方面所存在的共性，可能代表它们的长度特点，而它们的因人而异的长度排列，可能显示了发音人的个性。从词首[t^h]／[t]和[t∫^h]／[t∫]的标志性舌腭接触面积变化图中可以看出，[t^h]／[t]辅音的舌位主要分布在齿区内，是舌尖上齿辅音。而[t∫^h]／[t∫]辅音的舌位主要分布在齿龈区内，是舌尖齿龈辅音。  相似文献

高师音乐学专业课程体系改革探索     

黄池  杨蕾 《江西教育学院学报》2005,26(4):112-115

随着我国基础音乐教育改革的进一步深入，对中小学音乐教师提出了新的要求，高师音乐学专业现有课程体系已成为中小学音乐教育改革的瓶颈，也是其自身发展的障碍。要改革高师音乐学专业现有课程体系就必须把为基础教育服务、培养品质的中小学教师作为高师课程体系的构建理念，确立新的课程构建原则，使新课程体系具有先进性、民族性和时代性。  相似文献
