Waiter’s serve (WS) is a specific tennis serve posture frequently observed in young players, and commonly considered as a technical error by tennis coaches. However, biomechanical impact of WS is unknown. The aims of this study were to identify the potential consequences of WS in young elite players relating to performance and injury risk, and to explain the kinematic causes of WS. Serve of 18 male junior elite players (Top 10 national French ranking, aged 12–15 years) was captured with a 20 camera, 200?Hz VICON MX motion analysis system. Depending on their serve technique, the players were divided into two groups (WS versus Normal Serve [NS]) by experienced coaches. Injury data were collected for each player during a 12-month-period following the motion capture. Normalized peak kinetic values of the dominant arm were calculated using inverse dynamics. In order to explain WS posture, upper limb kinematics were calculated during the cocking and the acceleration phases of the serve.

In France, there are more than 150 engineering schools, training 11,000 engineers per year. If we add to these the schools of management of a comparable standard, we get the figure of 16,000 highly trained personnel per year.  相似文献

This article outlines the activities of the Council of Europe in favour of inter‐university co‐operation and exchange. First, the role and tasks of the CC‐PU and then the work programme of the Council of Europe on higher education and research are examined. With regard to academic mobility and European inter‐university co‐operation, the Transfrontier Regional University Co‐operation Programme, the European Postgraduate Training Programme, and the Inter‐university Co‐operation Programme between Europe and Latin America are described. Finally, both the European Networks for Scientific and Technical Co‐operation and the Open Partial Agreement on the Prevention of, Protection Against, and Organisation of Relief in Major Natural and Technological Disasters and their constituent activities are evoked.  相似文献

The purpose of this review, spanning over 12 years of publication of Distances et Médiations des Savoirs (DMS), formerly Distance et Savoirs (DMS) (2003–2014), is guided by the question why and how French-speaking researchers addressed the issues of time, workload and costs in distance learning, and how this was affected by the increasing influence of information and communication technologies.  相似文献

Purpose: Changing research design and methodologies regarding how researchers articulate with end-users of technology is an important consideration in developing sustainable agricultural practices. This paper analyzes a joint experiment as a multi-stakeholder process and contributes to understand how the way of organizing social learning affects stakeholders’ ownership of process outcomes. Design/Methodology/Approach:A learning group composed of the different stakeholders of the oil palm seed system in Benin was set around a joint experiment. We use a detailed account of the group dynamics to understand the social process. Findings: The way the process is designed and conducted has a great effect on the ownership by the participants. Methodological steps taken in this research process showed its efficacy to produce quick and positive feedback mechanisms. Stakeholders’ perspectives on what constitutes a quality oil palm seedling varied widely. Participants, mainly nursery holders, learned new production practices. Representatives of the research center learned a mismatch of recommendations with users’ contexts. Field observations further to the process indicate changes in practices among stakeholders that would be sustainable. Practical Implications: Beyond focusing on outcomes, initiatives in multi-stakeholder processes should also document and analyze social processes in order to better understand the mechanisms by which such processes foster socio-technical change, as well as identify potential institutional barriers to such processes. Originality/Value: Through a detailed analysis of group dynamics, this paper addresses an important knowledge gap in participatory agricultural development.  相似文献
