维生素E对不同运动强度的运动员的影响

人体在进行不同强度的运动时,随着运动时间的延长,自由基不断的增加积累。这样可造成运动性疲劳和肌体的损伤的发生。维生素E合理吸收利用直接关系到机体的运动能力和运动水平的发挥。本文阐述了维生素E抗氧化和清除自由基的机制,分析了维生素E与运动能力之间的关系,以及维生素E在运动实践中的应用。

Intelligent scientific authoring tools: Interactive data mining for constructive uses of citation networks

Many powerful methods and tools exist for extracting meaning from scientific publications, their texts, and their citation links. However, existing proposals often neglect a fundamental aspect of learning: that understanding and learning require an active and constructive exploration of a domain. In this paper, we describe a new method and a tool that use data mining and interactivity to turn the typical search and retrieve dialogue, in which the user asks questions and a system gives answers, into a dialogue that also involves sense-making, in which the user has to become active by constructing a bibliography and a domain model of the search term(s). This model starts from an automatically generated and annotated clustering solution that is iteratively modified by users. The tool is part of an integrated authoring system covering all phases from search through reading and sense-making to writing. Two evaluation studies demonstrate the usability of this interactive and constructive approach, and they show that clusters and groups represent identifiable sub-topics.     

An intercultural test of the generality of interpretations of nonverbal cues

This study examines Mehrabian's claim concerning the cross-cultural generality of implicit metaphors that underlie a set of coding rules for the interpretation of nonverbal behaviors. Responses of Japanese and American school teachers were used to discover whether observers from two different cultures interpret nonverbal behaviors during interpersonal communication according to the three-dimensional metaphorical scheme proposed by Mehrabian and to assess the degree of intercultural consensus about dimensions and interpretations. Factor analysis, factor structure comparisons, and multiple discriminant analysis yielded evidence of significant differences between groups both in the dimensions used and in the interpretations of nonverbal cues along those dimensions.     

Banach空间中K-正定算子方程解的逼近

本文研究了Ｂａｎａｃｈ空间中的Ｋ－正定算子方程解的一种逼近方法。我们把Ｋ 正定算子的概念从Ｈｉｌｂｅｒｔ空间,实可分严格凸的Ｂａｎａｃｈ空间和实可分ｑ一致光滑Ｂａｎａｃｈ空间（ｑ＞１）推广列了实可分Ｂａｎａｃｈ空间Ｘ。对这样的Ｘ,我们构造了一个强收敛于方程Ａｘ＝ｆ,ｆ∈Ｘ,的唯一解的迭代程序（其中Ａ是一个Ｋｐｄ算子,与Ｋ有相同的定义域）。在一定条件下,本文把Ｐｅｔｒｙｓｈｙｎ,Ｃｈｉｄｕｍｅ和Ａｎｅｋｅ,Ｃｈｉｄｕｍｅ和Ｏｓｉｌｉｋｅ等的相应结果推广到了实可分的Ｂａｎａｃｈ空间

大卫·刘易斯论因果性

现代哲学对于因果概念的讨论受惠于休谟,休谟关于因果概念有不同的定义。他除了从相继性、接近性和恒常联系三个特点定义因果关系,还从某种反事实条件关系描述了因果概念。大卫·刘易斯从事件之间的反事实依赖关系对因果性进行了细致分析,体现了剖析因果性概念的新视角,同时也充分表明大卫·刘易斯的模态实在论立场和反事实条件句逻辑在其系统哲学建构中的解释力。     

John Eggleston 1926-2001

In a collaborative classroom, teachers combine their strengths to work together, coach one another, and provide the best possible environment for their students. Similarly, peer coaching provides educators with a chance to utilize a natural support system at their school. When peer coaching is used in conjunction with collaborative teaching, it enhances teacher improvement and student learning by providing ongoing opportunities for educators to share their unique knowledge bases and expertise, allowing exploration of new ideas and expansion of professional skill repertoires.
