Optimal estimation of a finite population mean under generalized random permutation models

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations.     

“S+V+R+O”双核谓词格框架研究

在“S +V +R +O”句式中 ,由于述语中心动词V价的不同、宾语的不同 ,补语R语义指向的不同 ,主语S、述语V、补语R、宾语O构成一个复杂的语义网络。弄清楚其中的语义网络 ,就可以着手建立“S +V +R +O”双核谓词格框架了。建立双核谓词格框架 ,可以促进对句子的理解 ,促进现代汉语格系统的建立     

论中国20世纪90年代散文及其发展趋势

我国 90年代出现了一股“散文热” ,其主要标志和特点为 :散文队伍发展壮大 ,散文流派异彩纷呈 ;散文更贴近生活 ,更关注人生 ,更强调表现主体意识 ;散文理论探讨、争鸣十分活跃。但也有不足之处 :散文创作存在“泡沫”现象、“缺钙”现象、散文理论存在薄弱现象。 2 1世纪散文发展趋势 :“散文热”将会持续 ,“网络散文”将迅猛发展 ,散文与高科技的结合势在必行。

Guanxilization or categorization: psychological mechanisms contributing to the formation of the Chinese concept of “us”

中国社会心理学在面对急速的社会变迁中，需要以变迁与文化的视角来选择研究 问题，而中国社会文化中群己关系的社会心理机制，即“我们”概念的形成机制及其 转换的可能与条件，正是一个体现着双重视角的基本问题。对这一问题的探讨不仅有 助于解释社会凝聚力、群体行动的逻辑，讨论国家与个人、社会与个人、类别与个人 的关系；也有助于培植社会转型时期的社会心理资源和社会支持系统，从而促进社会 合作。与以往单一机制的分析框架不同，通过对两个个案的讨论，研究提出了一个 新的分析框架，即：中国人“我们”概念是在社会情境的启动和价值取向等因素影响之 下，经由相互交织的“关系化”与“类别化”双重过程形成的。

关键词: “我们”?概念?群己关系?关系?关系化?类别化

Faced with rapid social transformation, the discipline of social psychology in China needs to choose its research topics from the perspective of both change and culture. A basic issue reflecting precisely these two perspectives is that of the formation of the social psychology mechanism of individual‐group relations, namely the formation of the concept of “us” in Chinese society and culture, as well as the possibility and conditions for the transformation of this mechanism. Exploring this issue will not only help us to understand social cohesion and the logic of group behavior and to discuss the relationship between the state and the individual, society and the individual, and the category and the individual; it will also help cultivate social psychology resources and support systems at a time of social transition, and thus promote social cooperation.. Unlike previous analytical studies that focused on a unitary mechanism, this study uses the discussion of two cases to put forward a new framework for analysis: that is, the Chinese concept of “us” comes into being through the mingling of “guanxilization” and “categorization” under the influence of social context priming, value orientation and other factors.     

Two Moments of the Logitnormal Distribution

We display the first two moment functions of the Logitnormal(μ, σ²) family of distributions, conveniently described in terms of the Normal mean, μ, and the Normal signal-to-noise ratio, μ/σ, parameters that generate the family. Long neglected on account of the numerical integrations required to compute them, awareness of these moment functions should aid the sensible interpretation of logistic regression statistics and the specification of “diffuse” prior distributions in hierarchical models, which can be deceiving. We also use numerical integration to compare the correlation between bivariate Logitnormal variables with the correlation between the bivariate Normal variables from which they are transformed.     

Estimation under modified Weibull distribution based on right censored generalized order statistics

In this paper, the maximum likelihood (ML) and Bayes, by using Markov chain Monte Carlo (MCMC), methods are considered to estimate the parameters of three-parameter modified Weibull distribution (MWD(β, τ, λ)) based on a right censored sample of generalized order statistics (gos). Simulation experiments are conducted to demonstrate the efficiency of the proposed methods. Some comparisons are carried out between the ML and Bayes methods by computing the mean squared errors (MSEs), Akaike's information criteria (AIC) and Bayesian information criteria (BIC) of the estimates to illustrate the paper. Three real data sets from Weibull(α, β) distribution are introduced and analyzed using the MWD(β, τ, λ) and also using the Weibull(α, β) distribution. A comparison is carried out between the mentioned models based on the corresponding Kolmogorov–Smirnov (K–S) test statistic, {AIC and BIC} to emphasize that the MWD(β, τ, λ) fits the data better than the other distribution. All parameters are estimated based on type-II censored sample, censored upper record values and progressively type-II censored sample which are generated from the real data sets.     

The role of market-oriented relations in public relations: The differing perspectives of managers and practitioners in the U.S. and Taiwan

This study explored the role of market-oriented public relations. The study involved two surveys; one explored the perspectives of business managers and another of the perspectives of public relations practitioners, and compared their views concerning market-oriented and non-market-oriented relations. While business managers and public relations practitioners of non-market-oriented relations valued the contribution of market-oriented public relations to organizational effectiveness in terms of revenue generation and cost reduction, practitioners of market-oriented public relations ascribed their contribution to organizational effectiveness in terms of media publicity and exposure. This paper concludes with a discussion of practical applications and theoretical implications.
