Adaptive m estimation of symmetric distribution location

An adaptive M esitmation procedure for using a random sample to estimate the location parameter of an unknown symmetric distribution is developed. The procedure may be applied to samples from distributions with tail lenghts at least as heavy as normal distribution tails. Simulation studies demonstrate the potential of the new estimator for producing good location estimates.     

Simultaneous prediction intervals for all patrwise differences among several future sample means

Hahn (1977) suggested a procedure for constructing prediction intervals for the difference between the means of two future samples from normal populations having equal variance, based on past samples selected from both populations. In this paper, we extend Hahn's work by constructing simultaneous prediction intervals for all pairwise differences among the means of k ≥ 2 future samples from normal populations with equal variances, using past samples taken from each of the k populations. For K = 2, this generalization reduces to Hahn's special case. These prediction intervals may be used when one has sampled the performance of several products and wishes to simultaneously as- sess the differences in future sample mean performance of these products with a predetermined overall coverage probability. The use of the new procedure is demonstrated with a numerical example.     

On the maximal invariance of manova step down procedure statistics

Subbaiah and Mudhol kar (1978) remark the general mu1tivariate linear hypothesis testing step down procedure statistics do not appear to be maximal invariants under nonsingular lower triangular matrix transformations of the original variates. This paper proves the maximal invariance of these statistics. The invariance results are essential to study the power functions of the step down procedures for MANOVA problems. An example is given to show that such power function studies are very involved.     

Selecting all treatments better than a control using existing tables

In this paper subset selection procedures for selecting all treatment populations with means larger than a control population are proposed. The treatments and control are assumed to have a multivariate normal distribution. Various covariance structures are considered. All of the proposed procedures are easily implemented using existing tables of the multivariate normal and multivariate t distributions. Some other procedures which have been proposed require extensive and unavailable tables for their implementation     

“打”字的来源及读音考

历代都有人谈关于打字的问题。明末清初黄生认为,打由提（dǐ）字音转而来;清初李因笃认为,挞字变声调减笔画就成了打;王力先生认为,打读丁雅切与方言无关,把打的音变列入＂偶然性＂一类。其实,打字汉代就有,是朾的俗字。打字本音德冷切或都挺切,读如丁雅切是唐五代西北的方音现象,敦煌文献和现代西北方音均可为证。打的丁雅切后来上升为通语,南宋以后进入韵书,而德冷切或都挺切的读音则保留在吴语等方言中。     

Don't Ask,Don't Tell and Other LGB Civil Rights Issues: Effects of Terminology on Public Opinion

“Don't Ask, Don't Tell” was devised to combat the perceived costs associated with gays and lesbians openly serving in the military, including low unit cohesion, damage to the military's reputation, and the general population's lack of acceptance for homosexuals serving (Belkin, 2008). However, recent polls and policy reversal have shown growing public support for homosexuals being allowed to serve openly. Interestingly, the amount of support has varied as a function of question wording. Two polls conducted by CBS News found support for homosexuals serving in the military varied with greater support for “gays and lesbians” compared to “homosexuals.” Two studies were conducted to further examine the effect of terminology on reported support. Two samples reported opinions for homosexual civil rights issues. Sexual orientation was described using the terms gay men and lesbians, homosexuals, gay men, or lesbians. Percentage differences were found to be greater than those reported in the CBS polls, as wording choice had an effect on reported openness regarding homosexual civil rights. These differences indicate that it is important to consider precise terminology usage when measuring opinions. Levels of support, stereotypes activated, and the relationship between support for civil rights and general levels of prejudice were examined.     

“顺天致性＂：可持续发展教育“育人术”

“一年之计莫于种稻,十年之计莫于树木,百年之计莫于育人。”本文在借助瑞典可持续发展教育实践中“百年育人”的思维模式解读了中国古人“树木之道”成功与失败的原因后。认为基于“逆人之性以致其害”的今人“育人之困”,可持续发展教育的“育人术”必须是“顺天致性”。其行动应该是营造良好的生态环境,其方法则应是尊重多种多样的差异性,而其理想则是鼓励“学为创造”的自主性。     

论中原文化道、儒、法、释思想内核的形成

道家发端于中原,儒家见用于中原,法家原生于中原,释教首先落脚中原。中华文化的四大思想渊源与中原的密切关系,使它们最终演化为中原文化的思想内核。它们构成了中原文化的最深层结构,规定了中原文化的基本走向,也推进了中原文化的丰富与繁荣。
