A test for the equality of k medians against the simple tree alternative under right censorship

We consider a test for the equality of k population medians, θ_i i=1,2,….,k, when it is believed a priori, that θ _i: The observations are subject to right censorhip. The distributions of the censoring variables for each population are assumed to be equal. This test is compared with the general k-sample test proposed by Breslow     

虚拟社会分层——兼与现实社会分层比较

人类历次科技革命都对社会形态产生了巨大影响,今天信息技术革命对社会形态的显著影响表现为虚拟社会的兴起,使得社会存在两副社会结构:现实社会结构与虚拟社会结构。论题基于社会分层视角,对虚拟社会结构展开实证研究,将虚拟社会结构分为五个阶层,并对照其现实社会分层位置,研究发现虚拟社会分层将那些现实社会底层推向虚拟社会上层,而现实社会上层则处于虚拟社会底层。这种阶层位置倒置对现实社会秩序产生强烈的冲击,这也正是今天社会治理的重要面向。     

Probability density function of quotient of order statistics from the pareto,power and weibull distributions

This paper deals with the probability density functions of quotient of order statistics. We use the Mellin transform technique, to find the distribution of the quotient Z= X/Xwhere X.,X(i < j) are the ith and jth order statistics from the Pareto, Power and Weibull distributions     

The Synthetic Situation: Interactionism for a Global World

Presented as the Distinguished Lecture at the annual meeting of the Society for the Study of Symbolic Interaction in Boston, Massachusetts, on August 1, 2008, this article rethinks central assumptions of the interaction order as conceptualized by Goffman and others with respect to global domains of activity. 1 It proposes two new concepts, that of the synthetic situation and that of time transactions. Synthetic situations are situations that include electronically transmitted on‐screen projections that add informational depth and new response requirements to the “ecological huddle” ( Goffman 1964 :135) of the natural situation. Global situations invariably include such components; we also find that temporal forms of integration may substitute for joint territoriality of copresence in the natural situation. Based on research on global currency trading and other empirical examples, I identify four types of synthetic situations and describe the synthetic situation's informational character, its ontological fluidity, and the phenomenon that synthetic situations may become role‐others for participants. I outline the response system of synthetic situations, sketching out the concepts of response presence and its implications in this context as well as the importance of embodiment. I also discuss time transactions and the idea of fatefulness as a symbolic charge linked to the synthetic components of the situation.     

The power functions of the likelihood ratio tests for a simply ordered trend in normal means

Likelihood ratio tests for the homogeneity of k normal means with the alternative restricted by an increasing trend are considered as well as the likelihood ratio tests of the null hypothesis that the means satisfy the trend. While the work is primarily a survey of results concerning the power functions of these tests, the extensions of some results to the case of not necessarily equal sample sizes are presented. For the case of known or unknown population variances, exact expressions are given for the power functions for k=3,4, and approximations are discussed for larger k. The topics of consistency, bias and monotonicity of the power functions are included. Also, Bartholomew's conjectures concerning minimal and maximal powers are investigated, with results of a new numerical study given.     

Extreme statistics from the cosine distribution

The cosine distribution serves as a very good teaching example for which exact moment properties of extreme order statistics can be expressed in terms of elementary functions. This article presents the limiting joint distribution of the extreme order statistics for the cosine distribution. It is shown that burrows'(1986) result is a special case of the result presented in this article.     

Ranked set sampling with concomitant variables

Ranked set sampling is a procedure which may be used to improve the precision of the estimator of the mean. It is useful in cases where the variable of interest is much more difficult to measure than to order. However, even if ordering is difficult, but there is an easily ranked concomitant variable available, then it may be used to “judgment order” the original variable. The amount of increase in the precision of the estimator is dependent upon the correlation between the 2 variables.     

论我国法定继承制度的完善

我国《继承法》规定的法定继承制度,内容简单且不够全面。《继承法》应以我国《民法典》的制订为历史契机进行修订和补充,扩大法定继承人范围,增加法定继承顺序,强化配偶继承权的法律保护,完善代位继承制度等,以进一步完善我国的法定继承制度,并为《民法典》的制订打好基础。     

抗战时期“近卫声明”的来龙去脉

1938年的三次“近卫声明”，都是日本政府为找到一个代表中国的谈判对手达到其侵略的目标而发布的。第一次近卫声明打开了诱降的大门，第二次、第三次近卫声明则是在日本大规模侵华军事进攻告一段落和汪精卫暗通日本的情况下发布的，完全体现了政治谋略为主、军事进攻为辅的方针，目的在于从政治上瓦解国民政府。三次近卫声明之中，以第二次近卫声明影响最为巨大而深远。     

法律带来的是什么？——评《无需法律的秩序》

法律与秩序似乎存在着天然的联系,人们对二者之间的关系充满了＂想当然＂。《无需法律的秩序》打破了这种＂想当然＂,使人们看到一个无需法律的秩序,但这并不表明法律无用论。法律自有存在意义和必要,单纯的法律无用论和法律中心主义也许都需要批判。无需法律的秩序应当在法律力量中生存,而不会超出法律。
