Gap and Integration - Volunteer Service for Western China and College Students＇ Growth

大学生志愿服务西部计划的目的之一是大学生通过奉献社会来实：观个人成长。他们能否真正地成为当地社会中的一员,是实现这一目的的关键。在异文化环境之中,想短时间内成为其中一员并非易事,因为有一道浅浅的沟壑存在于青年文化与当地文化、当地人与外来人、青年人与长辈之间。为实现志愿服务效果的最大化,西部志愿者应该积极主动地融入当地社会．当地社会应对他们抱持开放的态度,他们与当地长辈之间应该展开对话,他们更应该战胜和超越自我。     

“五四”精神的内在本质和现代传承

“五四”精神由两个层面的内容构成。第一层面是“五四”精神的内在本质,主要由“五四”精神的核心点与精髓构成;第二层面是“五四”精神的外在表现形式,主要包括不怕困难顽强斗争的精神、改革创新的精神、与为民精神等。在全面落实科学发展观、构建社会主义和谐社会的新的历史时期,应结合时代的变化,从“五四”精神的上述两个方面入手．切实发扬传承好这份宝贵的精神遗产。     

Classification rules for triply multivariate data with an AR(1) correlation structure on the repeated measures over time

In this article we study the problem of classification of three-level multivariate data, where multiple q$q$-variate observations are measured on u$u$-sites and over p$p$-time points, under the assumption of multivariate normality. The new classification rules with certain structured and unstructured mean vectors and covariance structures are very efficient in small sample scenario, when the number of observations is not adequate to estimate the unknown variance–covariance matrix. These classification rules successfully model the correlation structure on successive repeated measurements over time. Computation algorithms for maximum likelihood estimates of the unknown population parameters are presented. Simulation results show that the introduction of sites in the classification rules improves their performance over the existing classification rules without the sites.     

Semiparametric inference of proportional odds model based on randomly truncated data

This paper studies the estimation in the proportional odds model based on randomly truncated data. The proposed estimators for the regression coefficients include a class of minimum distance estimators defined through weighted empirical odds function. We have investigated the asymptotic properties like the consistency and the limiting distribution of the proposed estimators under mild conditions. The finite sample properties were investigated through simulation study making comparison of some of the estimators in the class. We conclude with an illustration of our proposed method to a well-known AIDS data.     

Characteristic function estimation of non-Gaussian Ornstein–Uhlenbeck processes

Continuous non-Gaussian stationary processes of the OU-type are becoming increasingly popular given their flexibility in modelling stylized features of financial series such as asymmetry, heavy tails and jumps. The use of non-Gaussian marginal distributions makes likelihood analysis of these processes unfeasible for virtually all cases of interest. This paper exploits the self-decomposability of the marginal laws of OU processes to provide explicit expressions of the characteristic function which can be applied to several models as well as to develop efficient estimation techniques based on the empirical characteristic function. Extensions to OU-based stochastic volatility models are provided.     

On equality of ordinary least squares estimator,best linear unbiased estimator and best linear unbiased predictor in the general linear model

The equality of ordinary least squares estimator (OLSE), best linear unbiased estimator (BLUE) and best linear unbiased predictor (BLUP) in the general linear model with new observations is investigated through matrix rank method, some new necessary and sufficient conditions are given.     

从十七大报告谈我国民族研究的思路——兼驳民族研究的边缘化问题

中国共产党第十七次代表大会报告时于当前中国的社会形势进行了客观的评估,确定了今后的主要任务和目标,对我国各项事业的发展指出了方向.本文通过分析十一届三中全会以来中国的社会发展和历届党的全国代表大会的报告,尤其是十七大报告,结合我国民族问题的现实和研究情况进行思考.文章强调指出:在社会主义初级阶段,无论是执政纲领还是民族研究,都必须结合国情,服务于社会主义建设主流,针对民族研究中"边缘化"的趋势提出了一些看法.     

China’s modern image – contemporary Chinese art

Abstract

As a worldwide cultural phenomenon, contemporary art in China has not only been used as a diplomatic language but also a reflection of contemporary Chinese culture. Contemporary Chinese art, as an emerging field to display China’s global role, provides an important perspective to study China’s self-position in global relations, China’s diplomacy in exercising its soft power, contemporary Chinese culture, and the reinvention of China’s cultural/national identity in post-Mao China. Using the 2000 Shanghai Biennale and the Chinese pavilion at the 54th Venice Biennale as case studies, this article investigates how the fluid construct of Chineseness is successfully promoted and demonstrated through the government’s support of contemporary Chinese art.     

Investment model predictions of workplace ostracism on K–12 teachers’ commitment to their schools and the profession of teaching

The purpose of this study was to determine how the ostracism of K-12 teachers influences their commitment to their schools and commitment to the teaching profession. The investment model was used to situate ostracism as a predictor of teacher commitment. Participants were 200 full-time K-12 teachers who completed a survey assessing their experiences with ostracism at work and investment model variables (i.e., investments, quality of alternatives, satisfaction, and commitment). Results confirmed investment model predictions with teachers’ investments, quality of alternatives, and satisfaction predicting their commitment to their schools and profession. Results of mediation models also demonstrated that controlling for teachers’ investments and quality of alternatives, ostracism predicted commitment indirectly through its effect on satisfaction. This study revealed that teacher commitment is explained by investment model predictions, but after controlling for those predictions, is further explained by ostracism from teacher colleagues.
