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.     

"新理学"中"理""气"范畴的问题与症结

在“新理学”的形上学系统中 ,冯友兰借助于逻辑方法和柏拉图主义的新实在论思想对程朱的“理”“气”范畴进行改造性的诠释 ,力图给中国哲学重设一个纯形式的本体论基础 ,但这一努力却造成了冯氏“理”本体中人性道德内涵的缺失 ,以及形上与形下两个世界的二元对立。

南宋理学极盛的过程与原因试析

宋代理学到南宋孝宗、宁宗时期达到极盛 ,但无论从理学道统承传方面还是从社会政治条件方面看 ,孝宗之前的高宗朝实为理学发展的关键时期。理学由北宋时的民间之学发展到南宋时占主导地位的学派 ,活跃于高宗朝的程门弟子对二程学说的极力推展是一重要因素。同时 ,面对激烈的民族矛盾 ,高宗集团选择了主和派的妥协主张 ,并有意识地寻找与这一政策相适应的学术思想作为其理论根据 ,程系理学正是在这一现实政治需要中得到高宗集团的接纳、支持而逐渐繁荣兴盛起来。到孝宗朝 ,朱熹使理学形成庞大的思想体系 ,标志着中国古典哲学进入了一个新阶段。     

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。     

边远民族地区高校非专业大学英语教学环境的哲学分析

马克思主义哲学认为世界上一切事物和现象之间以及构成事物的诸要素之间存在着相互依赖、相互影响和相互作用。这种联系的观点同样适用于我国的大学英语教学。大学英语教学本身并不是孤立的,它的开展离不开一定的教学环境,教学环境是否有利于大学英语教学会直接影响大学英语的教学效果。改善和创设有利的校园环境和课堂环境是边远民族地区高校推进非专业大学英语教学改革、提高大学英语教学质量的重要途径。     

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.
