New goodness of fit tests for the Cauchy distribution

Some goodness-of-fit procedures for the Cauchy distribution are presented. The power comparisons indicate that the new tests possess good performances among the competitors, especially against symmetric alternatives. A financial data set is analyzed for illustration.     

Estimation of P{X < Y} for geometric—exponential model based on complete and censored samples

This article deals with the estimation of R = P{X < Y}, where X and Y are independent random variables from geometric and exponential distribution, respectively. For complete samples, the MLE of R, its asymptotic distribution, and confidence interval based on it are obtained. The procedure for deriving bootstrap-p confidence interval is presented. The UMVUE of R and UMVUE of its variance are derived. The Bayes estimator of R is investigated and its Lindley's approximation is obtained. A simulation study is performed in order to compare these estimators. Finally, all point estimators for right censored sample from the exponential distribution, are obtained.     

Generalized minimum aberration mixed-level orthogonal arrays: A general approach based on sequential integer quadratically constrained quadratic programming

Orthogonal fractional factorial designs and in particular orthogonal arrays (OAs) are frequently used in many fields of application, including medicine, engineering, and agriculture. In this article, we present a methodology and an algorithm to find an OA, of given size and strength, which satisfies the generalized minimum aberration criterion. The methodology is based on the joint use of polynomial counting functions, complex coding of levels, and algorithms for quadratic optimization and puts no restriction on the number of levels of each factor.     

Schematic saturated orthogonal arrays obtained by using the contractive replacement method

This paper presents a general method of constructing schematic saturated orthogonal arrays of strength two. We consider a class of mixed saturated orthogonal arrays produced from saturated symmetric orthogonal arrays by using the contractive replacement method, study the Hamming distances of the rows, construct their association schemes, and prove that they are schematic. Some examples are given to illustrate this construction method.     

Care in a Time of Austerity: the Electronic Monitoring of Homecare Workers’ Time

Austerity places intense pressures on labour costs in paid care. In the UK, electronic monitoring technology has been introduced to record (and materially reduce) the working time and wages of homecare workers. Based on empirical findings, we show that, in a ‘time of austerity’, care is reductively constructed as a consumption of time. Service users are constructed as needy, greedy, time‐consumers and homecare workers as resource‐wasting time‐takers. We point to austerity as a temporal ideology aimed at persuading populations that individual deprivation in the present moment, self‐sacrifice and the suppression of personal need in the here and now is a necessary requirement to underpin a more secure national future. Accordingly, women in low‐waged care work are required to eschew a rights‐bearing, present‐tense identity and are assumed willing to suppress their entitlements to lawful wages as a sacrifice to the future. By transforming our understandings of ‘care’ into those of ‘time consumption’, and by emphasizing the virtue of present‐tense deprivation, a politics of austerity appears to justify time‐monitoring in care provision and the rationing of homecare workers’ pay.     

远程教育在终身教育体系构建中的时代使命

终身教育是与知识经济社会相对应的教育体系。终身教育思想的意义在于教育过程是连续不断的,其本质是学习型社会和教育社会化。现代远程教育为中国终身教育发展提供了机遇。构建终身教育体系,建设学习型社会离不开远程教育的支撑。本文从远程教育与终身教育的关系入手,阐述了现代远程教育在构建终身教育体系中的功能,提出了远程教育在构建学习型社会中的作用。     

城乡结合部老旧社区的嵌入式治理

基于城乡结合部老旧社区治理的嵌入性特征,将嵌入性理论视角与存量规划新常态下老旧社区的治理创新诉求相关联,从理论和实践双重维度研究阐述城乡结合部老旧社区嵌入式治理的生成背景、行动策略与创新路径。现阶段,多元治理主体在助力城乡结合部老旧社区治理与改造过程中,为满足老旧社区基础性改造需求、超越传统治理的行政化倾向、实现内源性发展目标,业已形成资源型嵌入、功能型嵌入和融合型嵌入三种行动策略,但受复杂的治理情境和滞后的治理后管理机制的影响易面临适应性挑战。应通过激发社区居民主体能动性、推进社会资本再组织化、完善治理后管理机制等具体路径,推进城乡结合部老旧社区嵌入式治理的可持续发展。     

居住分异与社会距离

通过对一个新建社区的形成过程和居住现状的考察,分析了国内"居住分异"的社会分化现象。通过数据分析发现,居住分异以后,群体分化程度被强化了,它使居民之间的社会距离扩大、疏离感增强。这种状况不利于社会团结与和谐社会的建设。我国正处在城市化高速发展的进程中,如果没有明确的政策干预,任由房地产市场按照这样的情况发展下去,居住分异与社会距离问题会变得更加严重。     

中美大学生权力距离对比研究

在跨文化研究理论中,Hofstede提出的民族文化五维度是被广为接受的研究成果。根据权力距离维度理论,权力距离可以用权力距离指数来显示,他认为中国的权力距离指数高于美国。随着中国经济环境的变化和对外开放进程的加快,文化也会不断发展和变化。因此,在新的环境下研究中美权力距离差异具有现实意义。为了对比当下中美大学生的权力距离感知,在中美两所大学发放调查问卷,分别考察了两组学生对于教师、长者和家长所拥有权力的态度,并用SPSS对调查数据进行分析。结果发现,对于教师和长者,中国学生的权力距离显著高于美国学生,但是对于家长,两国学生并未表现出明显差异,这与Hofstede的研究结果不符。
