The residual effect of a growth-decay mechanism and the distributions of covariance structures

The product of two independent or dependent scalar normal variables, sums of products, sample covariances, and general bilinear forms are considered. Their distributions are shown to belong to a class called generalized Laplacian. A growth-decay mechanism is also shown to produce such a generalized Laplacian. Sets of necessary and sufficient conditions are derived for bilinear forms to belong to this class. As a generalization, the distributions of rectangular matrices associated with multivariate normal random vectors are also discussed.     

《汉书》应劭注偏正式双音词研究

《汉书》应劭注偏正式双音词数量最多,偏语素与正语素有10种语义关系。有名+名→名等16种构词方式。名词具有绝对优势。偏正式双音词的词性基本上是由充当正语素单音词的词性决定的。注释学的繁荣,特别是它对义项加以选择、限制的要求,促进了汉语偏正式双音词的发展。     

Distributions generated by perturbation of symmetry with emphasis on a multivariate skew t-distribution

Summary . A fairly general procedure is studied to perturb a multivariate density satisfying a weak form of multivariate symmetry, and to generate a whole set of non-symmetric densities. The approach is sufficiently general to encompass some recent proposals in the literature, variously related to the skew normal distribution. The special case of skew elliptical densities is examined in detail, establishing connections with existing similar work. The final part of the paper specializes further to a form of multivariate skew t -density. Likelihood inference for this distribution is examined, and it is illustrated with numerical examples.     

安置方式、人际交往与移民适应:江苏、浙江343户三峡农村移民的比较研究

本文依据对江苏、浙江两省6个县343户三峡外迁农村移民的调查数据，分析了相对集中与完全分散这两种不同的安置方式，以及由此所形成的两种不同的人际交往状况对外迁移民社会适应的影响。研究发现，从总体上看，移民在安置地的人际交往状况对移民的社会适应的影响十分显著。无论是移民之间的交往、还是移民与当地居民之间的交往，都会大大增强移民融入当地社会的程度。     

Weakly implementable social choice rules

Previous investigations have shown that a social choice function which is partially implementable must be characterized by pervasive veto power. This paper investigates how much additional latitude in the design of social choice functions, and how much relief from this vetoers result, can be achieved by examining multi-valued social choice rules and relaxing the requirement of partial implementability to a requirement that we call weak partial implementability. We find that the power structures which characterize partially implementable social choice functions, including the veto properties, also characterize weakly partially implementable social choice rules. The conclusion is that invoking multi-valuedness and implementation of appealing social choice rules in strong Nash equilibria. Our results apparently exhaust the possibilities for implementation in strong Nash equilibrium. If any implementation possibility results are to be achieved, they can apparently come only by weakening the equilibrium requirement.     

治安管理处罚方式的新发展

处罚方式是关于具体的处罚手段与类型的法律规定,在治安管理处罚中具有非常重要的作用。随着社会主体多元化,社会关系复杂化,治安管理处罚方式必然要多样化。国外的社区矫正制度尤其值得借鉴。

称谓的简化与繁化

汉语称谓有两种情况 ,一是官职称谓的简化 ,一是某方言区社会称谓的繁化。前者是随着社会的发展需要而使用经济的言语来表达 ,成为当前社会的一种时尚称谓 ,它简明、经济 ,也符合汉语双音化的发展趋势 ;后者是为了避免社会称谓的尴尬而采用的一种表达方式。汉语称谓虽然细致 ,但是也有难于称谓的域段 ,繁化称谓可以说是一种称谓空白的补偿方式。     

由社会主体到自然主体——论宋代文人投身自然的几种表现形式

宋代文人投身自然 ,实质上是一种由社会主体向自然主体的角色转换 ,这种角色转换表现为 4个层面 :在行为上诗酒山林、随遇皆乐 ;在心理上“安于冲旷、不与众驱”;在思想上“无愧于中、无责于外”;在感情上“不以物喜、不以己悲”。这四个层面归结到一点 ,则是抒写山水 ,营造“心灵屋宇”。文人们在这些“心灵屋宇”中流泄的是真挚的情感 ,人生的顿悟和孤芳自赏的高洁品格     

试论语言风格学研究中的几个问题

语言风格学是语言学研究的一个分支 ;文学风格学是文艺学研究的一门新兴学科。本文试从言语的格调、言语的语言化、风格形成的要素、语体与文体等语言风格学研究过程中的几个实际问题切入 ,认为语言风格研究对文学风格研究具有一定的穿透力
