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.     

人力资源管理理论整体性缺陷与对策

当前人力资源管理理论缺陷引起多方面的重视 ,这些缺陷可以归结为理论的整体性缺陷。对人力资源管理的定义、历史和研究方法的分析表明 ,人力资源管理概念上的不完整和冲突 ,研究对象、范围和方法的不全面 ,以及核心原理的缺失是造成人力资源管理理论整体性缺陷的根源 ,由此能够找到克服整体性缺陷的对策

论中国共产党在民族凝聚力系统中的核心地位

中国共产党在80多年波澜壮阔的奋斗历程中，始终以最广大人民的根本利益作为基本的出发点和最根本的落脚点。因而赢得了人民，确立了民族凝聚力的核心地位。党在民族凝聚力系统中的核心地位，不但为党领导人民在长期革命斗争中的历史实践所证明，也为党带领人民建立、巩固、完善、发展社会主义的现实实践所证明。而党在新世纪之初提出的“三个代表”的政治宣言，必将进一步赢得和凝聚人民，进一步验证党在民族凝聚力系统中坚不可摧的核心地位。     

毛泽东反封建思想论纲

毛泽东的反封建思想是毛泽东思想的重要组成部分 ,它由革命主题论、反封建核心论、反封建根本问题论及文化革命论等内容组成。毛泽东的反封建思想是中国民主革命及新中国前 2 8年反封建斗争实践的指导思想。但是 ,我们还应该看到 ,毛泽东的反封建思想并没有形成一个独立发展的完整思想体系 ,他长于对物质制度层面封建主义的批判 ,而对思想意识层面封建主义的批判则严重不足。这构成了整个毛泽东思想科学体系的严重不足。     

Empirical likelihood confidence intervals for the mean of a population containing many zero values

If a population contains many zero values and the sample size is not very large, the traditional normal approximation‐based confidence intervals for the population mean may have poor coverage probabilities. This problem is substantially reduced by constructing parametric likelihood ratio intervals when an appropriate mixture model can be found. In the context of survey sampling, however, there is a general preference for making minimal assumptions about the population under study. The authors have therefore investigated the coverage properties of nonparametric empirical likelihood confidence intervals for the population mean. They show that under a variety of hypothetical populations, these intervals often outperformed parametric likelihood intervals by having more balanced coverage rates and larger lower bounds. The authors illustrate their methodology using data from the Canadian Labour Force Survey for the year 2000.     

试论邓小平的“唯民史观”

邓小平以其卓越的政治智慧和伟大人格,终其一生执著追求、倡导和践行的是一种以最广大人民群众的根本利益为主导的价值观,确立并形成了具有中国共产党人鲜明特色的"唯民史观"。这既是邓小平一生价值追求的永恒目标,也是他为我们党所规定和树立的核心价值观。     

荣辱观教育的实现方法

进行荣辱观教育是社会主义道德建设的重要任务。荣辱观教育需要坚持正确的荣辱衡量标准，明确义利的辩证统一关系；坚持道德价值的一元与多元的有机结合；坚持原则性与灵活性的结合，使荣辱观教育既具有内在的逻辑性和层次性，又具有现实针对性和可操作性。     

论科技翻译中的“形似”与“神似”

文学翻译中所讨论的"形似"与"神似"的问题在科技翻译中也存在。科技翻译应分两部分来考虑翻译原则:一部分是除核心词语以外的部分,这里基本不用考虑"形似"与"神似"的问题,译文只求"准确,易懂"。另一部分是核心词语的翻译,即新出现的科技词语的翻译。翻译核心词语的时候,译者应该尽量争取做到译文与原文不仅"形似",而且"神似"。
