孙悟空的名号与《西游记》的主旨

《西游记》中,孙悟空的名号有一个美猴王-孙悟空-弼马温-齐天大圣-孙行者-斗战胜佛的变化,亦可称之为心与魔之间相交的变化。二者相交反映着孙悟空的心路历程,即求心-束心-放心-收心-正心的过程,而这也正是小说的主旨。且心魔相交之说在《西游记》主旨探求过程中始终是一条重要支脉而延绵不断,这与晚明大行其道的心学思潮有着紧密关联。     

古代汉语中物量表示法的发展演变

物量表示法是数量表示法的一个重要组成部分,弄清物量表示法在古代汉语各个时期的面貌及其发展演变,有助于汉语史的研究。本文探讨了古代汉语各个时期的物量表示法及其发展演变状况。     

“江郎才尽”新解

“颠覆阅读”的“难以为继”,在文学史上的印证就是“江郎才尽”。对“江郎才尽”,文学史上有多种解释,此处认为,江淹是以“颠覆阅读”的手段来使自己的诗歌达到一种独特性,故意用一种怪诞或隐晦的文风,用一种奇哨怪仄的意境或修辞手段,来实现自己诗歌的新鲜感甚或冲击力,以震撼人们视觉、听觉,但这种文风难以为继,文学史告诉我们,“颠覆阅读”也是需要创新的。     

A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.     

个人教育收益率的估计与比较: 一个半参数方法

 本文运用一种变系数部分线性模型扩展了传统的明瑟人力资本收入函数,并提出了对明瑟函数中“平行性”假设的一种检验方法,以分析个人教育收益率如何受到工龄等因素的影响。通过对1991、2000以及2004等年度国家统计局城镇居民收入调查数据的分析,揭示出近二十年来我国城镇居民中不同工龄的人们的教育收益率存在明显区别,其中人教育收益率最高的始终是在1980年代中后期参加工作的群体。对导致我国教育收益率这种特殊现象的原因作了分析。     

Block and Basu bivariate lifetime distribution in the presence of cure fraction

This paper presents estimates for the parameters included in the Block and Basu bivariate lifetime distributions in the presence of covariates and cure fraction, applied to analyze survival data when some individuals may never experience the event of interest and two lifetimes are associated with each unit. A Bayesian procedure is used to get point and confidence intervals for the unknown parameters. Posterior summaries of interest are obtained using standard Markov Chain Monte Carlo methods in rjags package for R software. An illustration of the proposed methodology is given for a Diabetic Retinopathy Study data set.     

Tests of statistical hypotheses and their use in studies of natural phenomena

Contrary to ideas suggested by the title of the conference at which the present paper was presented, the author is not aware of a conceptual difference between a “test of a statistical hypothesis” and a “test of significance” and uses these terms interchangeably. A study of any serious substantive problem involves a sequence of incidents at which one is forced to pause and consider what to do next. In an effort to reduce the frequency of misdirected activities one uses statistical tests. The procedure is illustrated on two examples: (i) Le Cam’s (and associates’) study of immunotherapy of cancer and (ii) a socio-economic experiment relating to low-income homeownership problems.
