Skating start propulsion: three-dimensional kinematic analysis of elite male and female ice hockey players

The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete’s sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males’ maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics.     

实质性共链分析的实证研究——对全共链分析的修正

当前的共链分析研究主要沿用了共引分析的方法,但由于网络中充斥着大量的非实质性链接,就使这种共链分析的假设前提难以成立,分析结论的可信度低.在本文中,我们提出"实质性共链分析"作为对"全共链分析"的修正,认为"实质性共链分析"比"全共链分析"更有效,并以图书馆学情报学博客共链分析为实例验证了这一假设的正确性.     

Conservation of stained glass windows with protective glazing: Main results from the European VIDRIO research programme

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.

从"因材施教"到"市场导向"——市场经济中师德的具体呈现

在当今中国,由于市场经济的发展,教育领域也出现了"市场导向"的趋势,这虽然有其合理性和必然性,但也给"因材施教"的教育理念带来了巨大冲击,使其发生异变,使师德蒙垢.究其原因,是由于我国不成熟的市场经济和不完善的师德,这二者共同作用的结果.为此,要着力培育新时期的师德,使其在市场经济浪潮中也能有一份坚守的精神,促使教育理念回归正常.
