体育电影中的人文精神

人文精神是在人类社会发展过程中不断沉淀和提炼的精神文化的思想精髓,也是我国教育建设的指导理念。在人类社会步入信息时代的今天,以电影为媒介传播知识信息,弘扬人文理念已成为提高国民综合素质的重要途径。近几年,中国电影呈现蓬勃发展的繁荣景象,体育电影以其别具风格的艺术题材日渐展露出自身的社会价值,越来越受到人们的喜爱与认可。如何在体育电影中渗透人文精神,弘扬人文精神,传播人文精神,是当前体育电影发展与改革过程中值得思考的重要问题。     

信号相关性与DOA估计

窄带波达方向(DOA)估计模型中,相干信号的问题很容易引起混淆。一些文献简单地认为频率不同的信号是不相干的,而频率相同的信号就是相干信号。因此,在建立不相干信号的DOA估计模型时,采用不同中心频率的信号,而使用的方向矩阵却采用同一个信号频率,该文提出,当信号中心频率不同时,应采用各自相应的频率来建立方向矩阵。其DOA估计应采用宽带信号的DOA估计方法,也就是应该对不同的频率进行聚焦。而采用同一个频率来建立的方向矩阵恰好同聚焦后的信号模型相同,因此,其估计结果也就是正确的。但这样的信号模型与事实并不相符。该文严格按照相干信号的定义证明了只有频率和初始相位都相同的窄带信号才是相干信号,最后通过计算机仿真验证了这一点。     

Why do able‐bodied people take part in wheelchair sports?

Recently able-bodied people have taken up wheelchair sports. This paper aims to explore why people are taking up a sport which may be considered to 'belong' to disabled people and explore the impact of reverse integration. A questionnaire covering demographic details, experiences of wheelchair sport and perceptions of both able-bodied and disabled wheelchair athletes was distributed by e-mail via elite wheelchair athletic associations in the UK, Canada, The Netherlands and the USA. Twenty participants were recruited (11 disabled athletes, four female, and nine able-bodied athletes, three female). Able-bodied people initially became involved in wheelchair sports in order to share an activity with their disabled friends or family. Continuing participation was reinforced by friendship, challenge, achievement, the opportunity for good competition, development of the sport and to change society's perceptions of disability. Perceptions varied according to the policies relating to inclusion adopted by the sports governing body within the participants' countries.     

Inference for circular distributions and processes

One approach to defining models for circular data and processes has been to take a standard Euclidean model and to wrap it around the circle. This generates rich families of circular models but creates difficulties for inference. Using data augmentation ideas which have previously been applied to this problem in the framework of an EM algorithm, we demonstrate the power and flexibility of Markov chain Monte Carlo methods to fit such classes of models to circular data. The precision of the technique is confirmed through simulated examples, and then applications are given to multivariate and time series data of wind directions.     

Two-way analysis of variance for data from a concentrated bipolar Watson distribution

The bipolar Watson distribution is frequently used for modeling axial data. We extend the one-way analysis of variance based on this distribution to a two-way layout. We illustrate the method with directional data in three dimensions     

2008’北京奥运效应及其旅游影响分析

自第一届奥运会以来,每届奥运会的举办都为举办国带来了巨大的经济效益和社会效益。根据奥运会的影响作用,我们提出了"奥运效应"的概念,以此来分析奥运效应对举办国旅游业的作用,特别是对2008'北京奥运所带来的效应进行了探讨,在此基础上,提出了2008年北京奥运旅游最大化的开发战略。

制约大众体育消费的社会因素及对策

改革开放20多年来,随着城镇居民收入水平逐年提高,人们对身体健康越来越关心,对体育消费的需求也在不断增加,但是居民用于体育消费方面的支出比例却很低。体育消费除了受到经济以及其它因素的影响,主要还受到居民预期收入的不稳定性、社会过分追求体育商品化、对群众体育投入少等方面的影响。     

体育院系体育教育专业设置体操类综合课程的构想--体操、健美操、艺术体操、舞蹈综合课程

目前,我国体育院系体育教育专业体操类课程存在的问题是:课程设置分化、教学内容重复等。针对这问题,本文提出设置体操类综合课程的构想。综合课程应以“健康第一”思想为指导,选择健身知识技能、终身体育价值大的内容,把课程中共性较多的、联系较大的内容相整合,实现课程内容的最优化。     

肇庆学院教工羽毛球爱好者运动损伤情况调查

对肇庆学院38名教工羽毛球爱好者进行了运动损伤情况的调查,共查出损伤66人(次),不同类型的损伤17种,损伤次数总计132次.多数伤者未采取有效的方法治疗,而仅依靠自然恢复.对此,应加强对运动者的指导,健全运动康复的手段,以达到科学健身的目的.
