On nonparametric profile analysis of several multivariate samples

A unified development is offered for asymptotically distribution-free profile analysis of several multivariate samples. This includes as special cases procedures based on generalized U-statistics and also those based on linear rank statistics. Furthermore, it includes as special cases analysis of location profiles and also scalar profiles. Finally, asymptotic power and consistency properties are discussed for tests of hypotheses and subhypotheses of interest.     

A note on the joint distribution of correlated quadratic forms

In the present paper, the authors obtained exact and asymptotic expressions for the joint distribution of correlated quadratic forms when the underlying distribution is a multivariate normal.     

Approximation of power in multivariate analysis

We consider the calculation of power functions in classical multivariate analysis. In this context, power can be expressed in terms of tail probabilities of certain noncentral distributions. The necessary noncentral distribution theory was developed between the 1940s and 1970s by a number of authors. However, tractable methods for calculating the relevant probabilities have been lacking. In this paper we present simple yet extremely accurate saddlepoint approximations to power functions associated with the following classical test statistics: the likelihood ratio statistic for testing the general linear hypothesis in MANOVA; the likelihood ratio statistic for testing block independence; and Bartlett's modified likelihood ratio statistic for testing equality of covariance matrices.     

“三权分立”与“五权宪法”思想三大比较

孟德斯鸠系统地阐述了"三权分立"的思想,并明确提出了分权制衡理论.五权宪法思想是孙中山三民主义学说中民权主义的重要组成部分,是对西方资产阶级"三权分立"思想的重要发展.对"三权分立"与"五权宪法"的比较,应从两大思想的立论基础、构成形式和分权实质等方面入手.虽然"三权分立"与"五权宪法"思想都有历史局限性,但不可否认,它们是中西政治思想发展史上两座辉煌的历史丰碑.     

战后社会主义运动的大发展对中国执政党建设的影响

运用历史唯物主义观点分析了战后世界社会主义运动的大发展对即将执掌全国政权的中国共产党建设产生的重要影响:促使中国共产党由一个革命党成为一个执政党;促使中国共产党实现了执政方略的重大转变;促使中国共产党建立了高度集中的计划经济体制。     

乡村权力互动实证研究——以鄂西黄村为个案

随着新的《村民委员会组织法》的颁布,我国村民自治建设进入了规范化阶段,乡村之间的权力关系因此也得以确认。但现实生活中乡镇政权与村民委员会之间仍然处于一种模糊不清的交织状态。作者以鄂西黄村的实地调查来了解当前乡村权力的真实现状。     

政治文化与当代官场小说概论

政治文化对官场小说有着深刻的影响。当代反腐政治文化在题材和主题上规约着当代官场小说,表现为题材的新闻性和主题的反腐性。同时,传统政治文化包括"官本位"观念、道德自律和权术文化等,也对当代官场小说创作产生了影响,使当代官场小说成为折射传统政治文化的一道不可或缺的风景。     

论我国相对集中行政处罚权的合法性

相对集中行政处罚权是我国的一项制度创新,但是这一创新存在着是否合法的问题。从我国的试点城市看,这种相对集中行政处罚权在权力来源、权力行使主体和权力范围等方面与法律存在冲突。为此,在制度创新的同时,我们需要制定配套措施,解决合法性问题,以实现我国法制的统一性。     

Inference Based on Conditional Moment Inequalities

In this paper, we propose an instrumental variable approach to constructing confidence sets (CS's) for the true parameter in models defined by conditional moment inequalities/equalities. We show that by properly choosing instrument functions, one can transform conditional moment inequalities/equalities into unconditional ones without losing identification power. Based on the unconditional moment inequalities/equalities, we construct CS's by inverting Cramér–von Mises‐type or Kolmogorov–Smirnov‐type tests. Critical values are obtained using generalized moment selection (GMS) procedures. We show that the proposed CS's have correct uniform asymptotic coverage probabilities. New methods are required to establish these results because an infinite‐dimensional nuisance parameter affects the asymptotic distributions. We show that the tests considered are consistent against all fixed alternatives and typically have power against n^−1/2‐local alternatives to some, but not all, sequences of distributions in the null hypothesis. Monte Carlo simulations for five different models show that the methods perform well in finite samples.     

文化软实力的三重审视--以科学技术为基点

科学技术在社会发展中的具体形式表现为:作为知识形态的科学技术;作为生产形态的科学技术;作为意识形态的科学技术。作为知识形态的科学技术是文化软实力资源的重要组成部分,其本身的更新和发展也丰富了文化软实力的资源。作为生产形态的科学技术促进了文化软实力资源信息化,渗透到文化软实力构成要素之中,为文化软实力奠定了技术基础。在资本主义社会,尤其在晚期资本主义社会中,科学技术意识形态化,成为该社会的意识形态,被用来为资本主义制度的合法性和资产阶级统治的合理性进行辩护,提升资本主义国家的文化软实力。
