《学生体质健康标准》测试指标及相关性研究

教育部、国家体育总局颁布了《学生体质健康标准（试行方案）》,在实施过程中,存在不少值得思考的问题。文章针对山西大学在校学生随机抽样进行研究,结果表明：现行《标准》指标体系缺乏科学性,评价标准比《国家体育锻炼标准》低,不利于激励学生积极锻炼身体。《学生体质健康标准（试行方案）》的修订应坚持“科学性”和“合理性”的原则,才能更好地践行“健康第一”的教育思想。     

Wavelet goodness-of-fit test for dependent data

We introduce a new goodness-of-fit test which can be applied to hypothesis testing about the marginal distribution of dependent data. We derive a new test for the equivalent hypothesis in the space of wavelet coefficients. Such properties of the wavelet transform as orthogonality, localisation and sparsity make the hypothesis testing in wavelet domain easier than in the domain of distribution functions. We propose to test the null hypothesis separately at each wavelet decomposition level to overcome the problem of bi-dimensionality of wavelet indices and to be able to find the frequency where the empirical distribution function differs from the null in case the null hypothesis is rejected. We suggest a test statistic and state its asymptotic distribution under the null and under some of the alternative hypotheses.

马克思恩格斯对资本主义的环境批判及意义

19世纪40年代初，在主要资本主义国家还没有颁布早期环境立法之前，马克思恩格斯就开始关注人类的生存环境问题。他们具体地考察和分析了资本主义条件下环境污染的类型、状况和危害，深刻揭示了造成环境污染的认识根源、阶级根源和社会根源，并富有卓见地提出了解决环境问题的可能性途径。这些思想对认识和解决今天的生态环境问题具有重要价值。     

Properties of Bayes Factors Based on Test Statistics

Abstract.  This article examines the consistency, interpretation and application of Bayes factors constructed from standard test statistics. Primary conclusions are that Bayes factors based on multinomial and normal test statistics are consistent for suitable choices of the hyperparameters used to specify alternative hypotheses, and that such constructions can be extended to obtain consistent Bayes factors based on likelihood ratio statistics. A connection between Bayes factors based on likelihood ratio statistics and the Bayesian information criterion is exposed, as is a connection between Bayes factors based on F statistics and parametric Bayes factors based on normal-inverse gamma models. Similarly, Bayes factors based on chi-squared statistics for multinomial data are shown to provide accurate approximations to Bayes factors based on multinomial/Dirichlet models. An illustration of how the simple form of these Bayes factors can be exploited to generate easily interpretable summaries of the experimental 'weight of evidence' is provided.     

人与环境——如何重新解读中国哲学的"天人合一"理念

源于西方社会的“环境伦理革命”使人们把目光投向了中国哲学的“天人合一”理念。但是,中国传统哲学的“天人合一”理念并没有把自然物纳入道德关怀。因此,必须对“天人是一”、“天人相分”和“天人合一”三个命题进行重新诠释,以阐明“人”和“天”的关系,实际上是人和环境的关系。人与环境本来是不可分割的一体存在,整个世界就是“我(大我)”本身,只是由于人的“自我意识”的作用才有所谓人(小我)与环境的区分和对立。所以,追求与环境的协调和统一正是作为能动者的人的行为的应当。     

Inference for general parametric functions in box‐Cox‐type transformation models

The authors propose a simple but general method of inference for a parametric function of the Box‐Cox‐type transformation model. Their approach is built upon the classical normal theory but takes parameter estimation into account. It quickly leads to test statistics and confidence intervals for a linear combination of scaled or unsealed regression coefficients, as well as for the survivor function and marginal effects on the median or other quantité functions of an original response. The authors show through simulations that the finite‐sample performance of their method is often superior to the delta method, and that their approach is robust to mild departures from normality of error distributions. They illustrate their approach with a numerical example.     

提高日语专业学生口语能力之我见

提高日语专业学生口语能力,首先是教师要"动"起来,克服授课的枯燥乏味,遵循外语(日语)"不仅要用脑记,必须用身体的全部去记忆"的教授法原理及日语的特点进行授课;讲课模式要有创意;注重背景知识的介绍;使授课内容生动活泼。同时,要积极引导学生养成良好的听说习惯,促使学生的嘴巴"动"起来,把学到的日语知识变成自己的语言表达出来。
