On a class exhibiting trend change in average failure rate

Abstract

Weak convergence and moment convergence issues are investigated for the New Better than Average Failure Rate (NBAFR) family (introduced by Loh (1984 Loh, W. Y. 1984. A new generalization of the class of NBU distributions. IEEE Transactions on Reliability R-33 :97–113[Crossref], [Web of Science ®] , [Google Scholar])). We explore the validity of these results in the context of a more general ageing class that we introduce. We prove some new properties of this class and derive its interrelationships with other non-monotonic ageing families. Reliability and moment bounds are obtained and an interesting characterization of exponentiality is proved. Special cases of our results lead to new theorems for the NBAFR class. Finally weak convergence and related issues are established for this class.     

论邓小平对选拔培养中青年干部的思想

建设有中国特色的社会主义市场经济 ,需要一大批杰出的人才。如何选拔培养中青年干部成为我们党和国家一项重大课题。运用邓小平理论中关于选拔培养中青年干部的观点并指导实践 ,将会对我国的四化建设起到积极作用     

论邓小平的代价观

邓小平在领导中国改革开放和社会主义现代化建设的过程中 ,针对中国的特殊情况 ,他不仅对中国社会发展的代价问题进行深入思考 ,而且还指出中国在改革开放中产生代价的客观必然性以及如何正确看待改革中的代价问题。     

两汉文献中的经籍传注——《两汉全书》编纂杂识之一

在全部两汉文献中，为前代或当世古籍所作的各种“传”、“注”、“解”、“说” 、“笺”、“诂训”、“章句”等，占有很大的比重。这些经籍传注是基于对一定专书整体考察而作出的系统注解，与此前散见的训诂资料有所不同，已具有一定的学术个性，是一批具有相对独立意义的学术著作。它们的应时产生，是经学繁盛的直接结果，也反映了经学发展对一般古籍研究的影响，以及经学占主导地位的情况下汉代社会之多元文化的发展。《孟子章句》与《楚辞章句》是一直为后世所重的两种章句体传注，前者推崇孟子、后者赞颂屈原，曾在中国思想史、学术史上产生过深远的影响。     

交往理性：哈贝马斯的理性重建

哈贝马斯是在分析交往行为和生活世界的过程中建构起交往理性概念的。他是以工具理性和交往理性二元分立为基点,赋予交往理性以对抗工具理性的使命,通过“交往理性”这种新理性观的确立,解除了意识哲学的“先验主体”和“先验理性”的设定,摒弃了主、客体二元对立的思维方式,从而取消了主体中心主义的独裁,从根本上否定了狭隘的传统的“理性”观,也为现代人逃离现代性困境提供了一个可能的方向。     

A Bayesian Analysis for Accelerated Lifetime Tests Under an Exponential Power Law Model with Threshold Stress

In this paper, we present a Bayesian methodology for modelling accelerated lifetime tests under a stress response relationship with a threshold stress. Both Laplace and MCMC methods are considered. The methodology is described in detail for the case when an exponential distribution is assumed to express the behaviour of lifetimes, and a power law model with a threshold stress is assumed as the stress response relationship. We assume vague but proper priors for the parameters of interest. The methodology is illustrated by a accelerated failure test on an electrical insulation film.     

The econometrics of female labor supply and children

This is a survey of applied econometric research on the effects of children on female labor supply. Reasons for interest in the topic, and a basic model and terminology, are reviewed. Concerns are raised about the possible endogeneity of child status variables, and about the instrumental variables approach for dealing with this problem. Alternative ways of conceptualizing and estimating child status effects are considered, together with selected empirical evidence. Relevant developments from the household demand literature are summarized. Basic issues of model choice are also discussed.     

李白与杜甫面面观

围绕李白与杜甫的生平行事及其诗歌创作,从八个层面进行对比论述,所谓“以诗证史,有裨于知人论世”。文中既综合了当代的研究成果,也提出了一些新的见解。     

论18世纪后期英国对中国西藏的渗透政策及其破产

在18世纪后期,英国受当时社会历史条件的限制,对我国西藏实行以建立直接交往关系为主的渗透政策。由于喜玛拉雅地区各国在历史上同我国西藏形成的密切关系及其在地缘政治上的屏障作用,英国在这一地区的扩张活动同它建立印藏直接交往的尝试一样,都是其对藏渗透政策的组成部分。英国在廓尔喀侵藏战争中的卑劣表演最终导致了其对藏渗透政策的彻底破产。
