“合作竞争、三维评价”在高校田径教学中的运用

本文通过文献资料分析,走访和问卷调查等手段,设计了＂合作竞争、三维评价＂策略,并通过教学实验加以检验。研究结果表明：与传统教学方式相比较,＂合作竞争、三维评价＂策略能较好地激发学生的学习动机,提高学生学习的积极主动性,真正发挥教师的主导作用与学生的主体作用,学生学习成绩提高显著,为学生全面素质发展起到了良好的导向作用,在高校体育教学中是可行的。     

身体视域下近代音乐实践中体育话语的生成逻辑

近代音乐中的体育话语清晰呈现了从新身体至新国民进而新国家的逻辑思路,与之揭示音乐中体育话语所蕴含的力度。在现今国家提倡先进文化引领和鼓励文化创新的背景下,论证音乐中身体话语所具有的文化内涵,阐释音乐与体育的互动关系,以及其文化价值的传承与延续,既有助于增强其国家层面的说服力,更有助于处理音乐在体育和人生层面的现实处境。本文采用文献资料、逻辑思辨等研究方法,以近代身体话语为主线,重点考察音乐实践中体育话语的生成逻辑。研究认为：近代音乐实践中,创造新身体是体育话语生成的逻辑起点;塑造新国民则成为体育话语生成的应然逻辑;而构建新国家是体育话语生成的逻辑终点。     

分形集的模拟与维数计算

分形维数的定义突破了拓扑学中集合维数都是整数的局限,从整数维到分数维,是数学理论的重大变革与发展.文章在研究分形维数基本理论的基础上,采用递归算法,通过计算机编程,对几个分形集进行了模拟,计算出其相应的分形维数.从实验可以看出,这些分形集具有某种自相似的形式,一般分形集的分形维数严格大于其相应的拓扑维数.     

理性与自由：理解人与自然关系的两个维度

理性和自由是人的存在方式的两个维度,人在理解人与自然关系的时候离不开理性维度和自由维度。因而对理性和自由进行解读,理解理性和自由之间的冲突,以马克思主义辩证法的视角理解理性和自由之间的关系,对于理解人与自然的关系,具有一定的理论意义和现实意义。     

Ours to reason why

Abstract

This is a story of what happened on the Aiguille du Grepon. It is based on fact and designed to reveal both the appearance and reality of motivation in climbing, a combination that is often difficult to express in a traditional academic style. The story differentiates motivation along two dimensions, a goal dimension with intrinsic and extrinsic rewards at opposite ends and a relational dimension with exclusive and inclusive rewards at opposite ends. These polar opposites are integrated in the experience of outdoor adventure through the story. They are further reflected in the attitudes of a previous generation of climbers. It is suggested that these motivations define the games of outdoor adventure in general, and that we should be self-conscious of them both in education and in play.     

滇池流域1974年至2008年土地利用的分形动态

在遥感与GIS技术的支持下,通过滇池流域从1974年-2008年近35年间时间序列上的土地利用分类数据监测流域整体景观与分地类的分形维动态,试图从分形视角为滇池流域土地利用政策的制定提供理论依据,协调高原湖滨城市发展和湖泊生态系统保护.结果表明:①流域内各地类的形态呈现分形维特征,分形维数从植被覆盖类型(荒草地、农用地和林地)到裸地与建成区、水体依次减小;②近35年来滇池流域景观的整体分形维数持续上升,逐渐接近于临界值1.50,其结构稳定度持续下降,趋于随机运动的不稳定状态;③农用地与建成区的分形维数均呈“逐渐提高后稍有降低”的变化趋势,荒草地分形维数的变化趋势则相反,林地的分形维数总体呈上升趋势,裸地与水体的分形维数总体呈下降趋势.城市建成区快速扩展过程中农用地的占用与补给所导致的一系列土地利用变化是滇池流域土地利用分形维数与结构稳定度变化的主要驱动因素.滇池流域在制定区域土地开发和利用政策时,应以控制流域整体分形维数的提高、保证流域景观整体的结构稳定度为基本原则,进行建设用地的空间蔓延管制,将发展的重心转移到旧城的改造与更新,对零星分布于林地与荒草地过渡地带的农用地贯彻退耕还林还草政策,将耕作条件良好且邻近分布的农用地整治连片.     

The importance of having a flexible scope ISO 15189 accreditation and quality specifications based on biological variation – the case of validation of the biochemistry analyzer Dimension Vista

Introduction

Technological innovation requires the laboratories to ensure that modifications or incorporations of new techniques do not alter the quality of their results. In an ISO 15189 accredited laboratory, flexible scope accreditation facilitates the inclusion of these changes prior to accreditation body evaluation. A strategy to perform the validation of a biochemistry analyzer in an accredited laboratory having a flexible scope is shown.

Materials and methods:

A validation procedure including the evaluation of imprecision and bias of two Dimension Vista analysers 1500 was conducted. Comparability of patient results between one of them and the lately replaced Dimension RxL Max was evaluated. All studies followed the respective Clinical and Laboratory Standards Institute (CLSI) protocols. 30 chemistry assays were studied. Coefficients of variation, percent bias and total error were calculated for all tests and biological variation was considered as acceptance criteria. Quality control material and patient samples were used as test materials. Interchangeability of the results was established by processing forty patients’ samples in both devices.

Results:

27 of the 30 studied parameters met allowable performance criteria. Sodium, chloride and magnesium did not fulfil acceptance criteria. Evidence of interchangeability of patient results was obtained for all parameters except magnesium, NT-proBNP, cTroponin I and C-reactive protein.

Conclusions:

A laboratory having a well structured and documented validation procedure can opt to get a flexible scope of accreditation. In addition, performing these activities prior to use on patient samples may evidence technical issues which must be corrected to minimize their impact on patient results.
