中国人社会心态六十年变迁及发展趋势

在1949年后的六十年中,中国的经济基础和社会结构都发生了巨大的变化.与此相对应,中国人的价值观和社会心态也发生了显著的嬗变.在建国后的前三十年,中国共产党通过一系列政治运动实现了对中国社会的改造和整合,也使中国人的传统社会心理在分化变动之后走向高度同一;在建国后的后三十年,改革开放的伟大实践打破了僵化和保守的意识形态,中国人的社会心态在经历了一系列波折之后发生了积极的嬗变.经过六十年的变迁,中国人的价值观与社会心态变得越来越理智和成熟、越来越开放和多元、越来越主动和积极,也越来越具有全球意识.新中国六十年的"革命"和改革实践带给中国人的主观感受和心理积淀,在精神层面上赋予了中国独特发展道路以完整的价值和意义.     

Methods for calculating stationary distribution in linear models of time series

The article deals with methods for computing the stationary marginal distribution in linear models of time series. Two approaches are described. First, an algorithm based on approximation of solution of the corresponding integral equation is briefly reviewed. Then, we study the limit behaviour of the partial sums c ₁ η₁+c ₂ η₂+···+c _n η _n where η _i are i.i.d. random variables and c _i real constants. We generalize procedure of Haiman (1998) [Haiman, G., 1998, Upper and lower bounds for the tail of the invariant distribution of some AR(1) processes. Asymptotic Methods in Probability and Statistics, 45, 723–730.] to an arbitrary causal linear process and relax the assumptions of his result significantly. This is achieved by investigating the properties of convolution of densities.     

Nonparametric regression with cross‐classified responses

In this article, we develop regression models with cross‐classified responses. Conditional independence structures can be explored/exploited through the selective inclusion/exclusion of terms in a certain functional ANOVA decomposition, and the estimation is done nonparametrically via the penalized likelihood method. A cohort of computational and data analytical tools are presented, which include cross‐validation for smoothing parameter selection, Kullback–Leibler projection for model selection, and Bayesian confidence intervals for odds ratios. Random effects are introduced to model possible correlations such as those found in longitudinal and clustered data. Empirical performances of the methods are explored in simulation studies of limited scales, and a real data example is presented using some eyetracking data from linguistic studies. The techniques are implemented in a suite of R functions, whose usage is briefly described in the appendix.

从"南戏"说到《六十种曲评注》

南戏是中国文学艺术史上的一块瑰宝。明末清初著名学者毛晋,将南戏的著名文本编辑出版成《六十种曲》。今人又对毛氏的《六十种曲》进行校勘、标点、评注,并予以出版,书名曰《六十种曲评注》。本文以翔实的资料,全面阐述了南戏的发展演变、主要剧目及艺术成就;认真考证了《六十种曲》的版本变迁及各种版本的优劣得失;并对《六十种曲评注》一书做出了公允的评价。本文虽为一篇书评,但对南戏及六十种曲的研究,却有着较高的学术价值。     

Quadratic estimation in mixed linear models with two variance components

Explicit expressions for Bayes invariant quadratic estimates, biased and unbiased, are presented and proved to cover the entire class of admissible estimates in the considered classes. An unbalanced genetic model is studied for demonstration.     

An infinite class of PBIB designs

In this paper, an infinite class of partially balanced incomplete block (PBIB) designs of m+1 associate classes is constructed through the use of a series of row-orthogonal matrices known as partially balanced orthogonal designs (PBOD) of m-associate classes. For the purpose, a series of PBOD is obtained through a method described herein. An infinite class of regular GD designs is also reported.     

Generalized Youden designs: construction and tables

Generalized Youden Designs are generalizations of the class of two-way balanced block designs which include Latin squares and Youden squares. They are used for the same purposes and in the same way that these classical designs are used, and satisfy most of the common criteria of design optimality.We explicitly display or give detailed instructions for constructing all these designs within a practical range: when υ, the number of treatments, is ?25; and b₁ and b₂, the dimensions of the design array, are each ?50.
