继承 发展 创新——《现代汉语规范字典》成就管窥

《现代汉语规范字典》在《现代汉语词典》的基础上有很多创新和发展。收字方面 ,贯彻国家标准更自觉、更坚决。对字义的发展脉络梳理更清楚 ,对同音同形异义字的处理更为合理。强调立足于现实 ,对义项的增减分合更符合当前的语用实际。注意吸收新的研究成果 ,注意细致地观察生活实际 ,不少释义锤炼得更为精确。     

非封闭式收费公路逃费的博弈分析

为揭示非封闭式收费公路逃费的本质原因，规避逃费行为，运用博弈理论和期望矩阵模型对逃费现象进行分析。分析认为：在现有约束条件下，逃费者和参与逃费的村民、管理者在相互博弈中共谋逃费是其利益的最优选择。分析结果表明，治理逃费的根本途径在于降低公路收费标准，深化监管体制改革，科学布局公路收费站点。     

选本与经典:中国当代文学新规范的建立

中国当代文学新规范的建立滥觞于延安文学时期。建国后毛泽东的文艺思想成为唯一合法的文艺纲领，为了巩固文学的新规范，除了从政治文化上控制作家，把作家们纳入到体制内之外，还从文学选本上标示出文学创作的倾向。通过对作品不断经典化的过程，既对不符合新中国文学规范的某些现代文学作品进行了否定．又对当代文学的创作进行了示范性引领。选本与经典在巩固中国当代文学新规范上起到了推波助澜的作用。     

中国古代诉讼当事人的主体地位与诉权

中国古代社会是一个"权力本位"的社会,没有明确的权利概念,但并不能由此推论出中国古代法律就不保障权利。就诉讼而言,中国古代诉讼当事人绝非客体,而具有一定的主体地位,并享有多方面的诉权,只是相对于现代人来讲,其主体地位和诉权均不够充分。     

中国恩格尔系数下降原因新探

在使用恩格尔系数评价某个国家或地区某个阶段的生活贫富状况时，要结合恩格尔系数的具体影响因素，分清其下降的真正原因。论文从恩格尔系数的计算公式出发，认为它的基本影响因素是物价、品种数、各种消费品或劳务的购买量。利用因子分析法分析了导致居民恩格尔系数下降的五种可能的原因，并联系实际具体阐释。     

A BETA-OPTIMAL TEST OF THE EQUICORRELATION COEFFICIENT

This paper considers the problem of testing for nonzero values of the equicorrelation coefficient of a standard symmetric multivariate normal distribution. Recently, SenGupta (1987) proposed a locally best test. We construct a beta-optimal test and present selected one and five percent critical values. An empirical power comparison of SenGupta's test with two versions of the beta-optimal test and the power envelope shows the relative strengths of the three tests. It also allows us to assess and confirm Efron's (1975) rule of when to question the use of a locally best test, at least for this testing problem. On the basis of these results, we argue that the two beta-optimal tests can be considered as approximately uniformly most powerful tests, at least at the five percent significance level.

Structural Nested Models and Standard Software: A Mathematical Foundation through Partial Likelihood

Abstract.  In observational studies treatment may be adapted to the patient's state during the course of time. These covariates may in turn also react on the treatment under study, and so on. This makes it hard to distinguish between treatment effect and selection bias. Structural nested models aim at estimating treatment effect in such complicated situations, even when treatment may change at any time. We show that structural nested models can often be calculated with standard software, by using standard models to predict treatment as a tool to estimate treatment effect. Robins ( Survival analysis, Volume 6 of Encyclopedia of Biostatistics , John Wiley and Sons, Chichester, 1998) conjectured this, but so far it was unproven. We use a partial likelihood approach to choose the estimators and tests as a subclass of the estimators and tests in Lok (math. ST/0410271 at http://arXiv.org , 2004). We show that this is the class of estimators and tests that can be calculated with standard software. The estimators are consistent and asymptotically normal, and have interesting asymptotic properties.
