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.     

论经学对《汉书》义例的影响

经学对《汉书》的影响是深重的。经学对《汉书》义例的影响主要表现在两个方面：一是立名定目，依托经典；二是创立志表，弘扬经学。探讨经学对《汉书》的影响有助于解决一些史学问题。     

林庚白对宋诗派理论的反思与改造及其古典诗歌创作观

林庚白是南社的重要作家之一,研究近代文学的学人往往简单地视林庚白为宋诗派成员,但事实上宋诗不能涵盖林氏一生诗歌的情感内容和艺术风貌。从早年对同光体的追慕到后来对宋诗派的反叛和超越,林庚白对同光体宋诗派理论的内省与改造体现在藉诗写史的自觉性,情绪与情感的现代性以及以社会主义者之身世与怀抱而为诗三个方面,为传统诗词创作注入了新的精神　　气质和思想内涵。其五四以后的诗作也显示了旧体形式的诗歌在主动顺应历史潮流,渗入时代精神的条件下的内在生命力和创作实绩,不应为近现代文学研究所忽视。     

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.

"得"字句研究札记三则

我们认为 ,“得”字句的语义、结构中心在“得”后成分上 ,所以“把墙刷得白”不能说 ,是因为“把”字句表示一种处置 ,其后的谓语必然蕴含着实现这一时体意义 ,而作为有“把”的“得”字句中心的“白”是单个性质形容词 ,本身不包含实现这一时体特征 ;我们对范晓先生《复动“V得”句》一文中的用三个平面观点解释一种“得”字句提出一点疑问 ;对张豫峰以博士论文为基础发表的两篇论文中的观点和学风问题进行了批评。
