The Whole World in One Classroom: Teaching Across Traditions in a Cosmopolitan Environment

This paper reflects on the implications of exploring the intertextual strands of language and culture at work and play in an urban Canadian elementary school classroom in which the author became a teacher researcher. For close to three years, she documented the processes of writing, of action and reflection as part of a hermeneutical inquiry into the lived curriculum of the students and teachers engaged in working with culturally diverse texts and in becoming actors in the multiple plays of language for the purpose of both local and global communications.     

函数连接型神经网络应用于岩石含矿性研究

函数连接型神经网络是一种无隐含层的新型网络,应用其三阶联合激励增强特性对某矿区矿石与围岩进行判别研究,识别准确率近１００％．在对预测集的每一个输入信号添加２０％的噪音干扰后,发现依然能准确判别．可见网络的容错能力是十分令人满意的．     

基于荟萃分析方法的移动商务用户采纳研究

移动商务用户采纳是信息系统领域的研究热点。综合32篇相关研究文献中的数据,采用荟萃分析方法研究感知的有用性、感知的易用性、感知的乐趣、感知的移动性、个人创新、信任、主观规范、感知的成本等因素对用户使用移动商务的态度和行为意向的影响。结果表明,感知的有用性、感知的乐趣、信任、移动性和个人创新对用户采纳移动商务有显著的正向影响,感知的成本具有显著的负向影响,感知的易用性和主观规范的影响不显著。最后,对研究结果进行讨论,并提出对策建议。     

学科体系的解构与行动体系的重构--职业教育课程内容序化的教育学解读

就业导向的职业教育课程内容,应以从业中实际应用的经验和策略的习得为主,以适度够用的概念和原理的理解为辅。课程内容序化的哲学思考在于:作为一种知识序列,课程内容序化的最重要的目标指向,在于如何使学习的主体——学生容易地接受这一序列。因此,课程序化的教育学思考强调的是学生对知识的构建过程,应以工作过程为参照系整合陈述性知识与过程性知识。课程不再片面强调建筑在静态学科体系之上的显性理论知识的复制与再现,而是着眼于蕴含在动态行动体系之中的隐性实践知识的生成与构建。实际上,“工作过程导向课程”的开发过程,是一个伴随学科体系的解构而凸显行动体系的重构的过程。     

函数增强型神经网络应用于钢的冷弯性能研究

函数增强型神经网络（FunctionalEnhancedNet,简称FEN）是一种无隐含层的新型网络,作者应用其三阶联合激励增强特性对钢的冷弯性能进行判别研究,识别准确率近100％．对预测集的每一个输入信号添加噪音干扰,发现依然能准确判别．网络误差下降随着添加噪音的增大而逐渐变慢,可见该网络的容错能力令人满意．

Patellofemoral pain,body morphology and alignment in female pubertal dancers: One-year follow-up

The aim of this study was to assess changes in body morphology, anatomical alignment and prevalence of patellofemoral pain (PFP) in young female dancers along one year of pubertal growth, and to identify the risk factors related to PFP in these young dancers. Both legs of 60 dancers were evaluated during grade 7 and again after 1-year. At each of these points in time, the dancers were interviewed concerning their background, and anthropometric measurements, lower-limb physical examinations and knee ultrasound scans were performed. Morphological parameters changed significantly from baseline to follow-up. PFP was found in 53.3% of the dancers’ knees at baseline. At follow-up, 55.4% of the asymptomatic knees at baseline developed PFP, and only 9.4% of the symptomatic knees at baseline recovered. Lower BMI was identified among dancers who developed PFP during follow-up compared with dancers with no PFP, either at baseline or at follow-up. A positive grinding and positive Patellar Inhibition Test (PIT) were found to be risk factors for PFP at follow-up. A high prevalence of young dancers suffered PFP, from injuries they sustained mostly during the 1-year of dance practice. Parameters predisposing the dancers to PFP should be identified at early stages of dance class.     

新时代健康促进政策体系构建与高等体育教育改革研究

健康中国行动作为一项国家战略首次被提出,在顶层设计先行的国家治理理念引导下,未来一系列健康促进政策将要出台,在全社会为提升健康而行动起来的同时,国家的健康促进政策体系也在同步构建当中。相比之下,体育院校健康相关的专业设置和课程设置显得薄弱了许多。健康促进政策体系构建不仅是高等体育教育改革契机,同时也为高等体育教育专业、课程改革指明了方向。     

Biomechanical analysis of the “waiter’s serve” on upper limb loads in young elite tennis players

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.

电影武打动作设计对武术对练创编的启示——兼论武术对练的逻辑遗失

武术对练作为竞技武术的重要组成部分,承载着武术文化传承与传播的使命。但竞技武术对练中常出现“拳不触体”“等人”“等招”的问题,成为竞技武术对练发展的阻碍。以文献资料法、观察法和逻辑分析法,结合竞赛和武打编排经验,对竞技武术对练创编问题进行研究,旨在促进竞技武术对练项目的良性发展。认为,竞技武术对练创编应贯穿“为什么”话语,解决拆招与喂招的逻辑关系,可借鉴武打电影“角色塑造”“拳拳到肉”“情景设定”等演绎方法,实现“以假为真”的武术对练。
