Teaching students about information: Information literacy and cognitive authority

Scholarship has not undergone a paradigm shift in terms of argument and research with the introduction of the Web-based information world. Searching, on the other hand, has undergone a significant shift. In teaching students to find, use, and evaluate information, librarians and instructors need a useful model of the information world that enables them to teach students about information. A practical example of how this may be accomplished is presented.¹     

An assessment of training volume in professional rugby union and its impact on the incidence, severity, and nature of match and training injuries

A prospective cohort study was used to assess the influence of training volume on injuries sustained by 502 professional rugby union players in England. Training volumes (excluding warm-ups, cool-downs, and recovery sessions), player injuries, and player match exposure times were reported weekly. Higher training volumes (>9.1 hours per week) did not increase the incidence of match or training injuries. However, higher training volumes did increase the severity of match injuries, particularly during the second half, and consequently resulted in a significant increase in the number of days' absence due to match injuries. Although lower-limb injuries were the most common match and training injuries, shoulder dislocations/instabilities resulted in more days' absence during weeks of higher training volumes, but the differences were not significant. The least number of days lost due to injuries occurred during weeks of intermediate training volumes (6.2-9.1 h per week). Training volume was not correlated with final league position. Fitness testing, defence, and rucking and mauling components were identified as being very high- or high-risk training activities. Our results provide evidence of the benefits of modifying the volume and content of rugby union training to reduce the risk associated with injuries to professional players.     

帮助运动员支持1天进行2次训练

1天2次的训练通常是美国橄榄球进行比赛季节早期身体条件训练和许多其他运动项目进行常年运动训练的一部分。额外的训练有助于加速身体条件训练，给力量训练和技能发展留出时间，还有助于在队友中发展同志合作精神。1天2次训练的特点是强调体质的适应性。在夏季训练时，运动员频繁地置身于附加的湿热环境应激下。我们专家组就1天2次训练中的高能量需要、有限的恢复时间和“制造伤口”的心理应激问题进行讨论，基于科学理论和临床经验提出帮助运动员在1天2次的训练中获得最大的成效的策略。     

Developing Peer Groups for the Oregon University System: From Politics to Analysis (and Back)

In the fall of 1997, institutional research staff in the central office of the Oregon University System were asked to build a set of peer comparators for the state's seven diverse public universities. The peer groups were to serve the analytic needs of budgeting, performance measurement, and trend analysis. Because of several critical political issues requiring interinstitutional unity, the peer groups had to be developed and implemented with the participation and support of the seven university presidents. In addition, the peer groups had to be understood and accepted by board members, legislators, and the governor's office. Through a process that combined detailed statistical information with a sensitivity to the political dynamics and judgments of campus presidents and staff, the system office developed a set of peer groups that found acceptance in both the political and analytical environments. Ten conditions that contribute to the creation of peer groups on a systemwide basis are identified and offered as guidance to other university systems.     

西方美术的阴与阳

你能够闭着眼睛练习绘画吗？你用染发剂在浴巾上作画的本领又如何呢？ 对很多中国人来说，这样的问题听起来可能很荒唐．但是对于像我这样的西方人来说．这只是我们传统美术教育的一部分。相比技巧和细节，当代西方人越来越看重艺术的独特性和创造性。这种价值体系鼓励学生多去试验．不要畏惧失败。     

Delineating Professional and Amateur Athletic Bodies in Victorian England

By 1837, the sporting landscape of England was populated by a number of professional pedestrians who competed in a range of events that were extensively covered in the sporting press. These men distinguished themselves from their competitors through their use of ‘colours’ and a range of different athletic clothing. In the later stages of the nineteenth century, the dominance of the professional athlete was challenged through the formation of clubs and associations by a public-school- and university-educated middle class. The somatotype and clothing strategies of the Victorian athlete altered as a result. Their assumption of an innate physical superiority, allied to a preference for the all-rounder with his elegance and style, rather than the muscular, specialized sporting bodies of working-class professionals, were important features of an amateur ethos which drew much of its references from the Classical world. Through a discussion of how middle-class amateur athletes used Classical precedents, science and clothing to create the ‘university athlete’ and the ‘university costume’, in order to reinforce the distinctions between their own bodies and those of the professionals, this paper explores the transition from pedestrianism to organized athletics.     

Prospective Elementary Teachers’ Analysis of Children’s Science Talk in an Undergraduate Physics Course

We investigated how prospective teachers used physics content knowledge when analyzing the talk of elementary children during special activities in an undergraduate physics content course designed for prospective teachers. We found that prospective teachers used content knowledge to reflect on their own learning and to identify students’ science ideas and restate these ideas in scientific terms. Based on this research, we inferred that analyzing children’s ideas through videos provides a meaningful context for applying conceptual physics knowledge in physics courses. Activities that are embedded within a disciplinary curriculum, such as those studied here, may help prospective teachers learn to use disciplinary knowledge in exactly the type of activity in which their content knowledge will be most useful: listening to and interpreting children’s science ideas.
