汉代强化孝伦理的措施及社会影响

汉代倡导“以孝治天下”,将孝作为文化教育的重要内容,并通过奖励孝子、选拔有孝行的人为官、开展尊老活动等措施强化孝伦理教育。这些措施对汉代父母与子女的关系、师生关系、君臣关系和乡里社会的人际关系都产生了重要影响。     

Bounded Estimation in the Presence of Nuisance Parameters

The aim of this paper is to extend in a natural fashion the results on the treatment of nuisance parameters from the profile likelihood theory to the field of robust statistics. Similarly to what happens when there are no nuisance parameters, the attempt is to derive a bounded estimating function for a parameter of interest in the presence of nuisance parameters. The proposed method is based on a classical truncation argument of the theory of robustness applied to a generalized profile score function. By means of comparative studies, we show that this robust procedure for inference in the presence of a nuisance parameter can be used successfully in a parametric setting.

Deletion diagnostics for marginal mean and correlation model parameters in estimating equations

Regression diagnostics are introduced for parameters in marginal association models for clustered binary outcomes in an implementation of generalized estimating equations. Estimating equations for intracluster correlations facilitate computational formulae for one-step deletion diagnostics in an extension of earlier work on diagnostics for parameters in the marginal mean model. The proposed diagnostics measure the influence of an observation or a cluster of observations on the estimated regression parameters and on the overall fit of the model. The diagnostics are applied to data from four research studies from public health and medicine.     

Estimates of regression coefficients based on the sign covariance matrix

Summary. A new estimator of the regression parameters is introduced in a multivariate multiple-regression model in which both the vector of explanatory variables and the vector of response variables are assumed to be random. The affine equivariant estimate matrix is constructed using the sign covariance matrix (SCM) where the sign concept is based on Oja's criterion function. The influence function and asymptotic theory are developed to consider robustness and limiting efficiencies of the SCM regression estimate. The estimate is shown to be consistent with a limiting multinormal distribution. The influence function, as a function of the length of the contamination vector, is shown to be linear in elliptic cases; for the least squares (LS) estimate it is quadratic. The asymptotic relative efficiencies with respect to the LS estimate are given in the multivariate normal as well as the t -distribution cases. The SCM regression estimate is highly efficient in the multivariate normal case and, for heavy-tailed distributions, it performs better than the LS estimate. Simulations are used to consider finite sample efficiencies with similar results. The theory is illustrated with an example.     

严复海权思想初探

严复是我国较早接触与传播马汉海权论者。他借鉴马汉的海权理论形成自己的海权思想,认为海权关系到国家的贫富强弱和国际地位高下;不缔造海权,陆权也只能随之丧失。他呼吁我国应在日本海、渤海、黄海、东海与南中国海海域建立制海权,规复海军,实行海上交通控制,拒敌于海洋国土之外。其建立海权具有"国振驭远之良策,民收航海之利资"的政治与经济的双重目的,体现了其海权思想和国防观由传统向近代的转变。     

Estimators of the multiple correlation coefficient: Local robustness and confidence intervals

Many robust regression estimators are defined by minimizing a measure of spread of the residuals. An accompanying R ²-measure, or multiple correlation coefficient, is then easily obtained. In this paper, local robustness properties of these robust R ²-coefficients are investigated. It is also shown how confidence intervals for the population multiple correlation coefficient can be constructed in the case of multivariate normality.     

对孔融其人及其与曹操关系的再认识

孔融特立独行的个性、不为强权折腰的人格和忠诚于自己的政治信仰的品质,贯穿于他一生的行事之中。孔融与曹操的关系并非一开始就是紧张敌对、水火不容的,而是随着政治形势的发展有一个阶段性的发展变化过程。孔融的为人启蒙了后世文人的反抗、独立的意识。
