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.     

Simple detection of outlying short time series

Sets of relatively short time series arise in many situations. One aspect of their analysis may be the detection of outlying series. We examine the performance of standard normal outlier tests applied to the means, or to simple functions of the means, of AR(1) series, not necessarily of equal lengths. Although unequal lengths of series implies that the means have unequal variances, that are only known approximately, it is shown that nominal significance levels hold good under most circumstances. Thus a standard outlier test can usefully be applied, avoiding the complication of estimating the time series' parameters. The test's power is affected by unequal lengths, being higher when the slippage occurs in one of the longer series     

《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。     

古籍整理与方言的关系

本文分两个部分：第一部分讨论了古籍中因方言的存在而造成了异文和疑难词语的问题；第二部分讨论了古籍训诂应该重视方言的研究成果的问题。总之，本文旨在论述古籍整理与方言（包括古代和现代）研究的重要关系，不重视０方言研究的成果，就难以很好地做好古籍的校勘和训诂工作。     

手机短信诈骗及治理对策

随着手机短信业务的发展，利用手机短信进行诈骗的现象也频繁发生。短信诈骗行为的泛滥，不仅严重侵犯了人们的财产权益，而且破坏了正常的社会经济秩序。为有效预防和遏制手机短信诈骗，应强化监管和打击，建立和完善手机号码实名制和储蓄实名制，加强宣传教育，多管齐下，进行综合治理。     

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。
