Estimating the distribution function using k-tuple ranked set samples

The basic assumption underlying the concept of ranked set sampling is that actual measurement of units is expensive, whereas ranking is cheap. This may not be true in reality in certain cases where ranking may be moderately expensive. In such situations, based on total cost considerations, k-tuple ranked set sampling is known to be a viable alternative, where one selects k units (instead of one) from each ranked set. In this article, we consider estimation of the distribution function based on k-tuple ranked set samples when the cost of selecting and ranking units is not ignorable. We investigate estimation both in the balanced and unbalanced data case. Properties of the estimation procedure in the presence of ranking error are also investigated. Results of simulation studies as well as an application to a real data set are presented to illustrate some of the theoretical findings.

托马斯·阿奎那论宗教与政治

作为神学家和西方教会的代言人,阿奎那深入讨论了宗教与政治的关系问题,包括如何协调教权与王权的关系、如何对待异教徒、如何对待叛教者等。针对不同情况,他的政策也不相同,但其目的只有一个:在保持基督教国家内部稳定的前提下,打击异教力量和异端分子,维护和加强教会的势力。     

苏联专家事件与中国国内政治

在华苏联专家曾是中苏经济关系的纽带.然而随着20世纪50年代中苏关系的恶化和中国国内政策的左转,苏联专家在中国"大跃进"的特殊年代里已无用武之地.与此同时,中国已培养出一大批可以代替苏联专家的人才.中共已做好了应付突发事件的心理准备.苏联专家的撤走和中国自力更生口号的提出,标志着新中国自此改变了依靠苏援发展中国经济的方针.     

基于民俗仪式与符号阐释的《大傩图》补证

《大傩图》中人物极具符号性的装饰及道具所蕴含的民俗信仰因素,可以证明此图所画为仲春民间兼有驱傩、祈雨、娱乐功能的社火表演,更名为《社火图》较准确,不更名亦可。图中人物妆饰有“溪蛮”色彩,保有南方民族融合的痕迹。以执帚者为一号人物的一般说法可能有误,领队或一号人物当为蝶冠者。他们且行且吹打,滑稽搞笑,显然领队的临时掉头导致了队伍一团混乱,但此乱非真乱,抽去表象便可见队形乃呈反“S”或“龙抬头”状,属于(何意？)太极图式,具有深刻的寓意,且能最优化集中定格12个人物,如此匠心不能不令人击节。人物衣袍多着补子,而补子至明代方形成制度,故此图断代为宋值得怀疑。人物假面黑符至今仍存在于社火及戏曲脸谱中,当为我国戏曲脸谱之早期形式。     

民族认同的影像表达——以《建国大业》与《建党伟业》为例

《建国大业》与《建党伟业》是两部影响巨大的献礼影片，两部影片在历史事件选择与表达方面别具手眼，具有突破性。这种突破并非是一时兴起，而是指向了“民族认同”这一深刻主题。     

A modified LGB method for detecting significant effects based on a half-normal probability plot

In analyzing data from unreplicated factorial designs, the half-normal probability plot is commonly used to screen for the ‘vital few’ effects. Recently, many formal methods have been proposed to overcome the subjectivity of this plot. Lawson (1998) (hereafter denoted as LGB) suggested a hybrid method based on the half-normal probability plot, which is a blend of Lenth (1989) and Loh (1992) method. The method consists of fitting a simple least squares line to the inliers, which are determined by the Lenth method. The effects exceeding the prediction limits based on the fitted line are candidates for the vital few effects. To improve the accuracy of partitioning the effects into inliers and outliers, we propose a modified LGB method (hereafter denoted as the Mod_LGB method), in which more outliers can be classified by using both the Carling’s modification of the box plot (Carling, 2000) and Lenth method. If no outlier exists or there is a wide range in the inliers as determined by the Lenth method, more outliers can be found by the Carling method. A simulation study is conducted in unreplicated $2^4$ designs with the number of active effects ranging from 1 to 6 to compare the efficiency of the Lenth method, original LGB methods, and the proposed modified version of the LGB method.     

Can the welfare state replace parents? Children's cognition in the United States and Great Britain

We compare family and parental effects on child verbal facility, verbal achievement and mathematics achievement in the United States and Great Britain. We study 3,438 5–13 year-old children from the 1994 NLSY Child-Mother Data Set and 1429 same-aged children from the National Child Development Study, also known as the British Child. Multivariate analyses suggest that the processes through which families invest in child cognition are similar across societies, with factors including low birth weight, child health, maternal cognition, family size and children's home environments being consequential. We conclude that parental investments are equally important across the two societies. The more developed welfare state in Great Britain does not notably compensate for parental investments in that society, although it may play a greater role when parental resources are absent or stretched thin.

Market economies and pro-social behavior: Experimental evidence from Central Asia

This study seeks to extend the body of knowledge of pro-social behavior in comparative market settings by reporting on a high-stakes ultimatum game and revelation game experiments in two transition economies: Kazakhstan and Uzbekistan. While controlling for cultural differences and framing effects, we find statistically significant differences in fairness and honesty behavior between the two countries. Specifically, subjects in Uzbekistan (in an earlier stage of transition to a market economy) are fairer and more honest than their later-stage Kazakh counterparts. Our experimental findings have implications for the literature on pro-social behavior and market economies, and more generally, on the transmission process between formal and informal institutions.
