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.     

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。     

论当代大学生道德知行分离与协调

随着改革开放和社会主义市场经济建设不断深入 ,新观念、新思想层出不穷 ,许多落后陈旧的道德观念得到更新 ,同时也有一些腐朽、没落的道德观念沉渣泛起 ,还有一些似是而非的错误思想观念披着新观念的外衣 ,模糊了人们的视野 ,动摇了人们的善恶是非标准 ,这些都对传统道德提出了严峻的挑战。因此构建当代大学生的价值观和认识评价标准 ,既要弘扬和维系那些优秀的传统道德规范和观念 ,又要与时俱进 ,高扬时代精神 ,进行道德观念的创新 ,使爱国奉献、服务社会、爱岗敬业、诚实守信、创新进取等一系列基本道德规范和行为规范深入每一位大学生的日常生活和精神世界

本文通过调查分析,指出网络对我们的德育工作既带来了机遇,也带来了极大挑战;主张学校和老师应积极介入网络,加强对学生网上自我教育行为的引导,帮助、指导学生形成健康的主体性道德人格;德育老师要从当代大学生道德发展的特点入手,积极帮助学生从网络不健康的道德体系中摆脱出来,提高德育工作的实效;应引导学生树立正确的网络观念;协同家庭、社会各方共同实施网络道德教育,提高德育工作的有效性。     

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.
