失去脚后跟:荒诞的生存感

多和田叶子在《失去脚后跟》中以一种奇特的表现方式,抒写了现代人在异域文化冲突中荒诞的生存感受与生存处境,以及人与人之间的扭曲关系。通过对人物心理体验的挖掘和表现手法的分析,以及“失去脚后跟”诸意象隐喻意义的探寻,揭示了现代人的精神困境。     

电力市场理论的若干基本概念辨析

本文通过对电力市场、电价与电力交易模式等电力经济基础概念的分析,指出了现有概念体系的不足,并提出了作者的认识,尤其是对电力市场一般与市场特殊作出详尽分析,力图为构建竞争性的电力市场经济理论奠定微观概念的基础。     

行政人的伦理困境和伦理自主

行政人与其他人一样生活在复杂的社会关系下并承担着不同的角色,每一种角色都附带着一系列的义务与利益规定。角色冲突、利益冲突甚至是道德冲突产生的伦理困境,使得行政人经常处于两难的境地。因此,应从创设制度化的个人伦理生存空间、行政人对角色责任的清醒认识、弘扬行政人的个体独立人格、界定行政人的忠诚限度等方面帮助行政人找到既可保存公共利益又可保存自己人格完整的有效途径。     

Towards Enhancement of the Economy of a Thermal Power Generating System through Prediction of Plant Efficiency

The plant ‘Heat Rate’ (HR) is a measure of overall efficiency of a thermal power generating system. It depends on a large number of factors, some of which are non-measurable, while data relating to others are seldom available and recorded. However, coal quality (expressed in terms of ‘effective heat value’ (EHV) as kcal/kg) transpires to be one of the important factors that influences HR values and data on EHV are available in any thermal power generating system. In the present work, we propose a prediction interval of the HR values on the basis of only EHV, keeping in mind that coal quality is one of the important (but not the only) factors that have a pronounced effect on the combustion process and hence on HR. The underlying theory borrows the idea of providing simultaneous confidence interval (SCI) to the coefficients of a p-th p(≥1) order autoregressive model (AR(p)). The theory has been substantiated with the help of real life data from a power utility (after suitable base and scale transformation of the data to maintain the confidentiality of the classified document). Scope for formulating strategies to enhance the economy of a thermal power generating system has also been explored.     

元认知策略与外语学习

本文在介绍元认知内涵的基础上,通过对元认知在阅读理解和听力理解中作用的分析,阐述了元认知在外语学习中的作用和价值,论证了有效的外语学习离不开元认知策略。文章的结尾作者指出外语教学中应培养学生的元认知能力,教学生学会学习,对其进行终身教育并对此提出建议.     

音像业全球化趋势与我国音像业对外经贸策略的创新

在音像业全球化趋势下,尤其是随着加入WTO,我国音像业在对外经贸策略和规章方面存在的诸多问题日益暴露出来。因此,针对我国音像业对外经贸策略的不足,积极对音像业对外经贸策略进行创新,具有重要的理论价值和现实意义。     

关于学报发展中几个问题的思考

在互联网日益普及的情况下，高校学报不应等待观望，而应尽快转变认识，充分利用网络资源进行新的尝试，为自身的发展服务。高校学报要走的个性化特色化之路，通过对可资形成特色的各种条件进行创造性整合，形成刊物的个性与特色。注重提高刊物的学术影响力，提高所刊论文的引用率与引文率，在增强社会效益上做文章。同时，也要重视编排的标准化、规范化等工作，以期使学报的生存与发展进入良性循环。

A simple procedure for the selection of significant effects

Summary.  Given a large number of test statistics, a small proportion of which represent departures from the relevant null hypothesis, a simple rule is given for choosing those statistics that are indicative of departure. It is based on fitting by moments a mixture model to the set of test statistics and then deriving an estimated likelihood ratio. Simulation suggests that the procedure has good properties when the departure from an overall null hypothesis is not too small.     

Testing symmetry under a skew Laplace model

We develop tests of hypothesis about symmetry based on samples from possibly asymmetric Laplace distributions and present exact and limiting distribution of the test statistics. We postulate that the test statistic derived under the Laplace model is a rational choice as a measure of skewness and can be used in testing symmetry for other, quite general classes of skew distributions. Our results are applied to foreign exchange rates for 15 currencies.
