Interval estimation for conformance proportions of multiple quality characteristics

A conformance proportion is an important and useful index to assess industrial quality improvement. Statistical confidence limits for a conformance proportion are usually required not only to perform statistical significance tests, but also to provide useful information for determining practical significance. In this article, we propose approaches for constructing statistical confidence limits for a conformance proportion of multiple quality characteristics. Under the assumption that the variables of interest are distributed with a multivariate normal distribution, we develop an approach based on the concept of a fiducial generalized pivotal quantity (FGPQ). Without any distribution assumption on the variables, we apply some confidence interval construction methods for the conformance proportion by treating it as the probability of a success in a binomial distribution. The performance of the proposed methods is evaluated through detailed simulation studies. The results reveal that the simulated coverage probability (cp) for the FGPQ-based method is generally larger than the claimed value. On the other hand, one of the binomial distribution-based methods, that is, the standard method suggested in classical textbooks, appears to have smaller simulated cps than the nominal level. Two alternatives to the standard method are found to maintain their simulated cps sufficiently close to the claimed level, and hence their performances are judged to be satisfactory. In addition, three examples are given to illustrate the application of the proposed methods.     

洛克论宗教宽容

洛克的《论宗教宽容》,是现代西方处理宗教冲突的基本理论依据。但新近发现的文献表明,洛克早年是反对宗教宽容的。本文将洛克对宗教宽容的几次讨论放在十六十七世纪英国宗教冲突的政治背景之下,指出洛克前后期虽然主张不同,但都遵循同样的理论基础,即《第二篇政府短论》中提出的"神法—人法—兄弟法—私人法"的法律结构,只是针对英国现实问题,在这一框架当中适当调整。无论他主张宗教宽容还是不宽容,目的都是为了清除天主教在英国政治中的势力,围绕圣公会建立一个独立的民族国家。他晚年与普洛斯特有过多次争论,但所涉及的并不是原则性的分歧。我们今天思考宗教冲突与宽容问题,应该看到洛克宗教宽容思想的理论基础。     

Effects of Marriage and Children on Financial Risk Tolerance: A Synthesis of Family Development and Prospect Theory

Family development and prospect theory were used as a framework to predict variability in individuals' subjective financial risk tolerance within distinct family structures. Gender, age, and income were expected to interact with the main effects of family structure (marital status and children). Theory-generated hypotheses were examined in Study 1 (data from university housing respondents, n = 76) and Study 2 (the 1998 Survey of Consumer Finances, n = 4,305). One family structure main effect (child presence) was significant for investment risk tolerance in both studies. Family structure interactions (marital status × age and child × income) were significant for employment risk (Study 1), and child × age was significant for investment risk in Study 2.

乐教与儒者的宗教情怀

乐教是理解儒家精神不可忽视的重要方面。乐教扎根于“亲亲”之情,具体体现为与“忧患意识”有别,而与“安”“乐”相协调一致的“怛”和“哀”“悲”之情。此情实质上是超越的天道内化为人的心性而落实下来的生命意义与价值得以呈现的方式。儒者虽深知人生之哀、悲,但以乐入手,解悟和转化现实的人生与宇宙,是一大特色。如此,宗教情怀转化为现实的人生关怀,成为特有的礼乐文明的核心内涵。     

政府经济职能创新的路径选择

当前 ,在政府经济职能重新定位过程中 ,我们应特别关注以下三个问题 :产权保护制度、限政政府模式、社会风险承受能力。建立产权保护制度是政府经济职能重新定位的出发点 ;构建限政政府模式是社会主义市场经济的逻辑要求 ;以改革促稳定、建立良好的社会保障制度 ,从而提高社会风险承受能力 ,是为改革提供稳定社会基础的必经之途。按照这三方面的要求来创新政府经济职能 ,就可以使政府的经济职能基本上能够适应市场经济体制对它的客观要求     

基督教与佛教伦理思想比较研究

基督教和佛教都是高度伦理化的宗教 ,伦理思想是其宗教教义的重要内容。从伦理之来源、道德依据、行为规范、人性论、社会意义等方面对基督教和佛教的伦理观进行了比较 ,分析二者伦理观之同异 ,从而阐扬了两教的伦理价值。     

从《诗经》情歌看先民的宗教情结

情歌在<诗经>中占有非常重要的地位,其情节形象地再现了古代社会隆重的祭高禖仪式,这一仪式与先民的生殖崇拜密切相关,不仅反映了人们自由、奔放的性爱意识,揭示了人们对生命的热爱和重视,而且寄托着远古民族浓重的宗教情结,从而使<诗经>具有了深厚的人类学价值和深远的文化意蕴.     

艺术与宗教的缠绕和融合--论许地山与宗教文化的关系

作为一个对宗教经典十分熟悉的学者型作家,许地山在他的小说里常常自觉或不自觉地运用宗教意象,他的作品中艺术与宗教可说是互相缠绕、互相融合、密不可分.他既不用爱与美的理想来解释人生,也不用苦闷和悲哀来总结人生,而是以宗教思想为核心来探讨人生,并借作品抒发自己独特的人生感悟.无论是他的人生态度还是他的作品,都体现了佛教、道教以及基督教三者融合的影响.
