广西高校学报数字化出版平台建设探析

数字化出版发展迅速,但广西高校学报在数字化出版方面比较落后,仅仅是实现办公自动化、电脑排版,借助商业数据库把电子出版在网上传播。广西高校学报在运作数字化出版面临较多的困难。要取得数字化出版的发展,必须采取有效的措施。从广西高校学报的实际出发,可从以下方面着手：（一）组建数字化出版联合体;（二）分阶段建设。     

新型农村医疗保险中医方道德风险成因及对策分析

我国新型农村合作医疗保险从2003年开始推行,其采用第三方支付的方式,在解决农民因病返贫、致贫方面产生了积极的效果,但医方道德风险的普遍存在,对新型农村合作医疗保险存在很大的危害,本文通过对医方道德风险产生原因的分析,提出防范医方道德风险的对策。     

基于fused惩罚的稀疏主成分分析

本文旨在研究基于fused惩罚的稀疏主成分分析方法,以适用于相邻变量之间高度相关甚至完全相等的数据情形。首先,从回归分析角度出发,提出一种求解稀疏主成分的简便思路,给出一种广义的稀疏主成分模型—— GSPCA模型及其求解算法,并证明在惩罚函数取1-范数时,该模型与现有的稀疏主成分模型——SPC模型的求解结果一致。其次,本文提出将fused惩罚与主成分分析相结合,得到一种fused稀疏主成分分析方法,并从惩罚性矩阵分解和回归分析两个角度,给出两种模型形式。在理论上证明了两种模型的求解结果是一致的,故将其统称为FSPCA模型。模拟实验显示,FSPCA模型在处理相邻变量之间高度相关甚至完全相等的数据集上的表现良好。最后,将FSPCA模型应用于手写数字识别,发现与SPC模型相比,FSPCA模型所提取的主成分具备更好的解释性,这使得该模型更具实用价值。     

Heteroscedastic Global Tests that the Regression Parameters for Two or More Independent Groups are Identical

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad leverage points. The method used to identify leverage points can be important and can improve control over the Type I error probability. Results are illustrated using data from the Well Elderly II study.     

Self-validated Computations for the Probabilities of the Central Bivariate Chi-square Distribution and a Bivariate F Distribution. This work partially supported by National Science Foundation grant DMS-9500831

Self-validated computations using interval analysis produce results with a guaranteed error bound. This article presents methods for self-validated computation of probabilities and percentile points of the bivariate chi-square distribution and a bivariate F distribution. For the computation of critical points (c ₁,c ₂) in the equation P(Y ₁ @ c ₁, Y ₂ ≤ c ₂) = 1 ? α, the case c ₁ = c ₂ is considered. A combination of interval secant and bisection algorithms is developed for finding enclosures of the percentile points of the distribution. Results are compared to previously published tables.     

A permutation alternative and other test procedures for spatially correlated data in one-way anova

Research in many disciplines involves data with spatially correlated observations. Spatial dependence violates the independent errors assumption required for techniques such as the standard one-way analysis of variance for a completely randomized design. The testing methodology within the correlated errors approach has not been investigated within a spatial context. For one-way fixed effects analysis of variance, a permutation test and tests associated with the correlated errors approach are investigated through simulation. No single test was superior with respect to both power and size but the standard Wald F test and a simple adjustment to it performed well overall.     

国际实施最终反倾销措施统计分析：1995－2006

 本文利用WTO的统计数据,对1995－2006年间的国际实施最终反倾销措施进行了统计分析。本文分别分析了WTO时代国际实施最终反倾销措施的总体特点、国别或地区分布、产品结构、国别或地区与产品的混合分布,并在此基础上提出了值得进一步研究的问题。     

论社会企业的合法性

社会企业的组织形态与现行法律体系格格不入,产品受到公众质疑,定位受限于一线城市,导致在法规合法性、道德合法性与认知合法性等方面面临难题,并进而影响社会企业的经济效益与社会效益。鉴于此,唯有通过主动地适应或选择、改变或创造环境才能化解这一难题。     

Research Subject Advocate: A New Protector of Research Participants

In 2001, the National Center for Research Resources (NCRR) directed the 78 General Clinical Research Centers (GCRC) to develop a Research Subject Advocate (RSA) position. The RSA would report directly to the Principal Investigator (PI) of each GCRC and assure compliance of studies conducted on the GCRC with federal regulations and policies. Seven RSAs agreed to be interviewed about their new role. Website documents, electronic correspondence, and presentations at the first annual national meeting of RSAs were scrutinized using discursive analysis to shed light on this new organizational form and its potential for increased protection of human research participants. The RSA role actualizes the ethical principles of respect for persons, justice, and beneficence that are the foundation of the protection of research participants. The results also reveal the regulatory, institutional, collegial, and personal resources and barriers that assist the RSA in the successful implementation of the RSA role. In addition, issues important to the RSAs are described.     

Building a worldwide evaluation community: past, present, and future

This article describes recent efforts to build a worldwide evaluation community. It notes events that led to an almost 200 percent growth in the number of regional and national evaluation organizations in slightly more than one year. Profiles are provided on the present status of many national and regional evaluation organizations that participated in the W.K. Kellogg Foundation-sponsored international evaluation meeting in Barbados, West Indies. Afterwards, the authors engage in a scenario planning exercise to picture alternatives of what the future of international evaluation might look like.
