论汉代特进

汉代特进是一种主要加于列侯的位阶,体现的是身份和道德,可以出任其它官职。部分列侯通过特进加入朝廷秩序。特进是汉代君臣权势格局调适的结果,反映了汉代官僚等级制的变化趋势。     

Rank covariance matrix estimation of a partially known covariance matrix

Classical multivariate methods are often based on the sample covariance matrix, which is very sensitive to outlying observations. One alternative to the covariance matrix is the affine equivariant rank covariance matrix (RCM) that has been studied in Visuri et al. [2003. Affine equivariant multivariate rank methods. J. Statist. Plann. Inference 114, 161–185]. In this article we assume that the covariance matrix is partially known and study how to estimate the corresponding RCM. We use the properties that the RCM is affine equivariant and that the RCM is proportional to the inverse of the regular covariance matrix, and hence reduce the problem of estimating the original RCM to estimating marginal rank covariance matrices. This is a great computational advantage when the dimension of the original data vector is large.     

A simulation study on the influence of ties on uniform scores test for circular data

Uniform scores test is a rank-based method that tests the homogeneity of k-populations in circular data problems. The influence of ties on the uniform scores test has been emphasized by several authors in several articles and books. Moreover, it is suggested that the uniform scores test should be used with caution if ties are present in the data. This paper investigates the influence of ties on the uniform scores test by computing the power of the test using average, randomization, permutation, minimum, and maximum methods to break ties. Monte Carlo simulation is performed to compute the power of the test under several scenarios such as having 5% or 10% of ties and tie group structures in the data. The simulation study shows no significant difference among the methods under the existence of ties but the test loses its power when there are many ties or complicated group structures. Thus, randomization or average methods are equally powerful to break ties when applying uniform scores test. Also, it can be concluded that k-sample uniform scores test can be used safely without sacrificing the power if there are only less than 5% of ties or at most two groups of a few ties.     

On the Ghoudi,Khoudraji, and Rivest test for extreme‐value dependence

Ghoudi, Khoudraji & Rivest [The Canadian Journal of Statistics 1998;26:187–197] showed how to test whether the dependence structure of a pair of continuous random variables is characterized by an extreme‐value copula. The test is based on a U‐statistic whose finite‐ and large‐sample variance are determined by the present authors. They propose estimates of this variance which they compare to the jackknife estimate of Ghoudi, Khoudraji & Rivest ( 1998 ) through simulations. They study the finite‐sample and asymptotic power of the test under various alternatives. They illustrate their approach using financial and geological data.

论无能为力现象产生的制度根源

无能为力现象的产生与科层制度的构造存在着某些必然联系。通过数理分析,可以透视出导致无能为力现象的三个前提条件:晋级不可逆性,多层次性,递阶性;进而得出改变无能为力现状的对应性措施,即通过我国行政体制改革来改变这三个前提条件。

高校层次、类型与高校学术期刊生态群落

提高学报质量,无论是政府调控还是学报自身的改革都要根据高校自身的类型、层次的实际,以高校自身的学科为依托,或站在学科前沿,引领学科发展的方向;或办出自己的个性和特色。政府管理部门对高校期刊进行分层管理和分类指导。不同层次、不同特色的高校学报组成一个丰富多彩的学术期刊生态群落,在这个群落中,各类期刊都体现出它的生存价值。     

晚清吏治腐败原因探究

晚清以降,国家内忧外患频发,社会激荡突变.社会处于严重脱序状态,贪污腐化趁机滋生蔓长.影响到吏治腐败的原因很多,其中皇权至上、专制独裁,缺乏严格的法律监督机制是吏治腐败的根源.此外奢靡之风盛行、俸禄制度与现实脱节、以及因捐纳制度泛滥都在清末的吏治腐败中起到推波助澜的作用.以史为鉴,对晚清吏治腐败产生的根源进行全面探讨,有助于我们深刻吸取历史教训,在全面进行现代化改革和建设中提高警惕,使有中国特色的社会主义道路健康发展.     

基于顾客排队行为的专业服务等级的决策问题

对专业服务企业而言,提供服务专家的专业水平决定了服务的质量,因此如何决策专家的等级（体现专业水平的差异）是企业所不能回避的重要问题。企业选择高等级的专家能够给顾客带来更高的服务质量使销售收入增加,但同时会加大服务成本,因此企业需要权衡这两方面来做决策。文章以专业服务为研究对象,考虑专业服务企业面对以队列M/M/1来到的策略顾客,如何按照最优定价原则来定价并决策专家的最优等级以使企业利润率最大化,同时考虑专家不同的薪酬水平对企业最优决策的影响。证明结果显示对专家等级的决策主要受到两个主要因素的影响,一个是专家间能力分化的程度,一个是行业的专家的收入特征。
