The purpose of this study was to develop a portable force measurement system for ice hockey skating. The system consisted of three strain gauge pairs affixed to an ice hockey skate’s blade holder with wire leads connected to a microprocessor controlled data acquisition device carried in a backpack worn by the skater. The configuration of the strain gauges simultaneously determined the vertical and medial–lateral force components experienced by the blade holder with a resolution accuracy of 1.9 N and a coefficient of variation of 9.2%. On-ice testing of this system with subjects performing forward start, acceleration, and constant velocity skating permitted unencumbered, natural movement and demonstrated clear, unambiguous signal responses, high trial-to-trial repeatability, and easy data retrieval. The practicality and accuracy of this testing approach have many applications, such as a quantitative tool for skating force assessment to aid athletes and coaches, as well as providing the means to examine other skill-specific dynamics.  相似文献

Abstract

An empirical examination of accredited American higher education institutions was conducted to obtain baseline data regarding distance education copyright, intellectual property, and antitrust concerns. Additionally, a multiple‐case study involving ten of the top thirty accredited distance education institutions in America was conducted. Policy approaches were examined for all institutions, and differences were discussed between public and private institutions as well as between the following Carnegie Classification institutions: Research I and II, Doctorate I and II, and Master's I and II. Data indicated that, out of the schools surveyed, 22% of the institutions in these Carnegie Classification categories published copyright and intellectual property policies on their institution's Web site. In the case study, it was found that 90% of the institutions centrally controlled their distance education program administration as well as the copyright and intellectual property policies related to it.  相似文献

This study explored the role of student (e.g., age, language background, gender), home (e.g., parent/caregiver education), and school (e.g., school type, size) socio-demographic factors in students’ school (e.g., in-school arts tuition, arts engagement), home (e.g., parent/caregiver–child arts interaction), and community (e.g., arts attendance, arts tuition) arts participation. The sample comprised 1172 elementary and secondary school students from 15 schools. Findings revealed that student and home socio-demographic factors were the most salient in predicting arts participation across school, home, and community contexts. Age, gender, and prior achievement were the key student socio-demographic factors, while parent/caregiver education and occupation were also associated with students’ arts participation. Implications for practice and intervention pertinent to young people’s arts participation are discussed.  相似文献

Mentoring of Women Faculty: The Role of Organizational Politics and Culture   总被引:1,自引:0,他引:1  
This article reports on a key finding of a phenomenological study on the mentoring experiences of women faculty. The study revealed the political climate of the organization as an essential attribute of this experience. Women faculty identified organizational culture and gender issues that affected the mentoring they received. This study suggests the need for human resource and organization development initiatives to facilitate the provision of academic mentoring for women faculty—individually, departmentally, and culturally—as a means to foster transformation and change in academic institutions.Sharon K. Gibson is an Assistant Professor of organization learning and development at the University of St. Thomas. She received her Ph.D. in adult education from the University of Minnesota. She holds an M.S.W. degree and graduate certificate in labor and industrial relations from the University of Michigan and a B.S. from Cornell University. Her research interests focus on developmental relationships including mentoring and coaching, strategic human resource and organization development, and adult learning.  相似文献

A census and survey of schools in the district of Ga, Ghana, explored the nature and extent of private education, and compared inputs to public and private schooling. Three quarters of all schools found were private, with almost as many unregistered private as government schools. Several important differences between registered and unregistered private schools were noted, including age, fee levels charged, teacher salaries and class size. A range of inputs, such as teacher activity, availability of desks, chairs, libraries, toilets and drinking water, were used to compare inputs to government, unregistered and registered private schools. Some conclusions are explored about the potential role for the private sector in helping meet “education for all” targets.  相似文献
