Randomized response techniques for complex survey designs

Singh et al. ([13]) pointed out that the Randomized response (RR) technique proposed by Moors ([9]) is not desirable because it fails to protect the confidentiality of the respondents and they provided two alternative strategies free from the above drawback but limited to SRSWOR sampling only. In this paper, generalization of one of the strategies is provided for complex survey designs, wider class of estimators and for quantitative characteristics. Relative efficiency of the modified strategy is tested through empirical investigations. An erratum to this article is available at .

超深亚微米信号串扰分析

芯片设计进入深亚微米后,互连线效应(主要是信号串扰)对集成电路的影响越来越大。该文针对这种影响进行了分析,讨论了在不考虑耦合电容和考虑耦合电容的两种情况下噪声产生机理,建立了一个耦合电容分析模型,得出了噪声产生的原因,并提出了解决噪声的策略。根据设计实例并结合建立的模型,提出了实际芯片设计中有效地控制串扰的方法,取得了良好的效果。

以协商民主来提炼民意

完善的民意表达机制,是社会和谐与稳定的前提与基础.民意具有合法性、可塑性、扩散性等特征.民主与民意的区别在于,前者通过更具操作性的程序与机制使民意得以优化、提炼与升华,克服了民意的盲目与冲动带来的负面影响.我国有必要进一步完善社会主义的民主实现形式,推广协商民主,使民意传递机制制度化、正规化.     

Quadratic estimators of covariance components in a multivariate mixed linear model

It is known that the Henderson Method III (Biometrics 9:226–252, 1953) is of special interest for the mixed linear models because the estimators of the variance components are unaffected by the parameters of the fixed factor (or factors). This article deals with generalizations and minor extensions of the results obtained for the univariate linear models. A MANOVA mixed model is presented in a convenient form and the covariance components estimators are given on finite dimensional linear spaces. The results use both the usual parametric representations and the coordinate-free approach of Kruskal (Ann Math Statist 39:70–75, 1968) and Eaton (Ann Math Statist 41:528–538, 1970). The normal equations are generalized and it is given a necessary and sufficient condition for the existence of quadratic unbiased estimators for covariance components in the considered model.     

Local influence in multilevel models

The authors study the local influence of observations in multilevel regression models. To this end, they perturb simultaneously the variances, responses and design matrix. To measure the local change caused by these perturbations, they use generalized Cook statistics for the fixed and random parameter estimates. Closed form local influence measures also allow them to assess the joint influence of various observations. They suggest a simple computation method and illustrate their results using two examples.     

浅析伊斯兰教的生态观

伊斯兰教认为人与自然界万物都是真主的造化物,两者地位是平等的,人类只是真主的"代治者".伊斯兰教在强调爱护自然、与自然界和谐相处的前提下,主张把握自然的本质和规律,通过对自然界进行合理的开发利用,为人类造福.同时,伊斯兰教也坚决反对狭隘的功利主义、反对只顾眼前利益而忽视人类的长远利益.这些主张均对增强环保意识、促进人类与自然的和谐发展、维护正常的生态环境具有极大的指导意义.
