太原市阳曲县小学花样跳绳开展现状调查研究

本文通过文献资料法、问卷调查法、数理统计法、访谈等研究方法,以太原市阳曲县小学为研究对象,对小学开展花样跳绳进行调查研究。结果表明,花样跳绳携带方便,运动简单易行,受天气影响因素比较小;学生对花样跳绳的评价比较高,受到多数同学的喜爱,因此,在小学体育教学中开展较易。但在调查中发现,教师专业知识比较缺乏、学校领导重视程度不高、体育场地设施不完善等一系列问题的存在,从而影响了花样跳绳的开展。在此基础上,对太原市阳曲县小学花样跳绳的发展提出相应的建议。     

郑虔生平考略

郑虔是唐代中期一流的诗人和学者,也是著名的书法家、画家.他以博学见称,对天文、地理、军事、医药和音律、书画等皆有精深造诣,被人誉为"才过屈宋"、"道出羲皇"、"德宗一代".他特别受唐玄宗赏识,进献的诗文书画,被玄宗御笔亲题"郑虔三绝",成为著名佳话.同时,他和李白、杜甫、王维、岑参等人又是很好的诗朋酒友,尤其与杜甫交情深厚,二人为数十年的知交.

Three-dimensional kinematics of the lower limbs during forward ice hockey skating

The objectives of the study were to describe lower limb kinematics in three dimensions during the forward skating stride in hockey players and to contrast skating techniques between low- and high-calibre skaters. Participant motions were recorded with four synchronized digital video cameras while wearing reflective marker triads on the thighs, shanks, and skates. Participants skated on a specialized treadmill with a polyethylene slat bed at a self-selected speed for 1 min. Each participant completed three 1-min skating trials separated by 5 min of rest. Joint and limb segment angles were calculated within the local (anatomical) and global reference planes. Similar gross movement patterns and stride rates were observed; however, high-calibre participants showed a greater range and rate of joint motion in both the sagittal and frontal planes, contributing to greater stride length for high-calibre players. Furthermore, consequent postural differences led to greater lateral excursion during the power stroke in high-calibre skaters. In conclusion, specific kinematic differences in both joint and limb segment angle movement patterns were observed between low- and high-calibre skaters.     

Predictors of scoring accuracy: ice hockey wrist shot mechanics

The purpose of this study was to identify the stationary “wrist shot” technique (movement patterns) of the ice hockey stick that corresponds to the accuracy of puck trajectory. A total of 25 subjects participated in this study, ranging from high to low caliber players. Each performed ten successful wrist shots at four targets (two top corners, two bottom corners). Performances were evaluated by recording the movements of the stick’s shaft and blade and of the puck with a 3D motion capture system at 240 Hz. Kinematics of the shaft and blade of the hockey stick were examined using a multiple regression analysis to predict accuracy scores. In general, the results indicated that accuracy corresponded to release parameters (both puck release orientation and velocity), shaft bending and change in blade orientations; though, parameter weighting differed substantially for top versus bottom targets. Future studies are warranted to identify the whole body kinematic patterns associated with the hockey stick kinematics.     

Olympic Education and Cross-Cultural Communication

In recent years, Olympic education has received increasingly greater attention. It is not just Olympic host cities that have established specialized Olympic education prograrnmes across the board, but also non-host cities are developing Olympic education activities to different degrees. Olympic education has also become an important project in the Olympic preparatory work, and has been an important project in the preparations for the Beijing Olympics. How to understand Olympic education? There are many different ways of looking at it. This essay attempts to take the unique characteristics of Olympic education as a starting point to explore the important role played by issues of cross-cultural communication in Olympic education.

粤港澳三地政府科技奖励体系比较

比较分析粤港澳三地政府科技奖在奖项设置、参评方式、奖励对象、奖励等级与数量、评审组织、奖励方式等方面的异同和特点,发现广东省科技奖的行政色彩较为浓厚,政府部门作为主要提名者难以实质性落实提名责任,丰厚的奖励派生待遇偏离了科技奖励荣誉本身,缺乏对青年科技工作者的引导激励;澳门特区政府的科技奖与广东省科技奖较为相似,但其较为注重引导鼓励青年群体开展科技创新;香港特区政府的科技奖励注重发挥市场及社会组织的参与和管理作用.比较分析结果对完善广东省政府科技奖励体系的主要启示为:明晰非市场化激励机制和政策导向作用,进一步优化奖励对象结构,注重对青年科技人员的奖励,落实提名者责任,突出奖励的荣誉性和价值导向,实现与社会科技奖励的互补和协同发展.
