In this work, we describe a simple coarse-grained model of a barbell that can be used to determine the qualitative role of bar bend during a jerk. In simulations of this model, we observed a narrow time window during which the lifter can leverage the elasticity of the bar in order to lift the weight to a maximal height. This time window shifted to later times as the weight was increased. In addition, we found that the optimal time to initiate the drive was strongly correlated with the time at which the bar had reached a maximum upward velocity after recoiling. By isolating the effect of the bar, we obtained a generalized strategy for lifting heavy weight in the jerk. 相似文献

This study examines an emerging trend in state higher education finance policy: the use of an index to establish tuition and fee levels at public institutions. Based on a national survey of tuition-setting policies, this study documents the increasing use of an indexing formula to determine tuition levels. Factors encouraging this trend are examined, and questions that must be addressed by state and institutional policymakers in adopting such a formula are discussed. Policy implications for states and institutions are also considered. 相似文献

This study explored the concept of school connectedness and the factors that may influence its development with a sample of
Chinese adolescents. Six focus groups involving 52 high school students were conducted using a set of predetermined discussion
topics. Results indicated that the students fully understood the notion of school connectedness and could identify a number
of key influences affecting its development. These factors could be grouped under several domains including teacher care,
peer relations, broader school relationships, school disciplinary policies and practices, activities within the school’s guidance
and counseling program, and opportunities for talent development. The students were also able to suggest practical strategies
that schools might introduce to enhance and strengthen students’ acquisition of connectedness to school. The implications
from the findings are discussed with particular reference to implementing comprehensive school guidance and counseling program
in Hong Kong. 相似文献

The primary focus of this article is to illustrate how teachers can use contemporary socio-scientific issues to teach students about nature of scientific knowledge as well as address the science subject matter embedded in the issues. The article provides an initial discussion about the various aspects of nature of scientific knowledge that are addressed. It is important to remember that the aspects of nature of scientific knowledge are not considered to be a comprehensive list, but rather a set of important ideas for adolescent students to learn about scientific knowledge. These ideas have been advocated as important for secondary students by numerous reform documents internationally. Then, several examples are used to illustrate how genetically based socio-scientific issues can be used by teachers to improve students’ understandings of the discussed aspects of nature of scientific knowledge. 相似文献

AbstractThe National Library of Australia and the state libraries of New South Wales and Victoria each maintain separate collections of printed ephemera. The role of these collections and the policies used in the acquisition and selection of items for them are described, analysed and compared. The role of the public library local studies collections in helping to create a cooperative, nationwide approach to the acquisition of this material in Australia is discussed in relation to this national and state activity. The value of an understanding of the Australian situation is related to a research project to develop guidelines for collection policies for printed ephemera at the national and local levels in Wales. 相似文献
