On the distribution of quadratic forms in normal random variables

This paper provides necessary and sufficient conditions for a quadratic form in singular normal random variables to be distributed as a given linear combination of independent noncentral chi-square variables. Using this result, an extension of Cochran's theorem to quadratic forms of noncentral chi-square variables is derived.     

Complete convergence of the non-identically distributed pairwise NQD random sequences

ABSTRACT

In this article, we study complete convergence of the nonidentically distributed pairwise negatively quadrant dependent (NQD) random sequences by the moment inequality and terminating random variables,which extend and improve the previous relevant results.     

Optimal allocation of time points for the random effects model

In this article the problem of the optimal selection and allocation of time points in repeated measures experiments is considered. D‐ optimal designs for linear regression models with a random intercept and first order auto‐regressive serial correlations are computed numerically and compared with designs having equally spaced time points. When the order of the polynomial is known and the serial correlations are not too small, the comparison shows that for any fixed number of repeated measures, a design with equally spaced time points is almost as efficient as the D‐ optimal design. When, however, there is no prior knowledge about the order of the underlying polynomial, the best choice in terms of efficiency is a D‐ optimal design for the highest possible relevant order of the polynomial. A design with equally‐spaced time points is the second best choice     

广西壮族自治区自治条例之立法思考

广西壮族自治区自治条例立法曲折,其草案历经19稿,至今仍无法出台。究其原由主要在于对自治区自治条例的定位不准确,自身存在立法缺陷。在立法环境日渐成熟的情境下,广西应厘清对自治区自治条例的认识,适度掌握立法权限,制定出高质量的自治条例,为自治权的充分行使提供法律依据,为广西的民族法治建设奠定良好的法制基础。     

学术史研究及其在学科发展中的意义——以叙事学与比较叙事学为例

在学科的形成与发展中,对学科学术史的梳理是一项富于意义的工作.通过对学科纵向发展进程与横向扩展过程的考察,辨认其发展的轨迹,探寻其相关理论资源的源流,学科名称与核心概念的形成与确认,其实际研究逐渐扩展的进程,既与某些相邻学科发生部分重合、又超越它们并凸显出自身学科特征的状况等,将可以厘定学科发展的方向,发挥相关的学科优势,更好地促使新学科健康有益地成长.     

拒腐防变的历史明镜——读《居安思危——苏共亡党二十年的思考》有感

2011年是苏联解体、东欧剧变20周年,社会科学文献出版社出版的<居安思危--苏共亡党二十年的思考>,可谓正当其时.本文主要对<居安思危--苏共亡党二十年的思考>的选题、方法和重点内容三个方面进行了评析,认为这是一部导向正确的学术力作.也是一部创新之作,具有重要的理论意义和决策参考价值.该成果的出版,为我们总结经验、居安思危、拒腐防变,提出了一面历史的明镜.
