论戏曲对《儒林外史》的影响

《儒林外史》描写戏曲演出活动的目的 ,或是为了营造一个真实的环境 ,或是由此来刻划人物的性格。优伶鲍文卿是小说中为数不多的正面人物之一 ,作者塑造此形象的目的是将他与一些儒士作对比 ,从而突出读书人的行己无耻。“虽云长篇 ,颇同短制”是《儒林外史》最有特色的结构 ,然而此结构并非独创 ,是对《四声猿》之类的明清杂剧的仿照。《儒林外史》常以人物命运与行为的突转来增强讽刺效果 ,这显然是运用了戏剧性的表现手法     

试论网络环境对民法价值理念的影响

现行民法的价值体系是由自由、平等和公平组成的。网络环境的开放性(无国界性)、交互性特征为民法自由价值的实现提供了一个更加广阔的空间;网络环境的开放性、虚拟性特征使安全和效率成为民法的重要价值目标;网络环境的数字化、技术性特征扩大了现行民法中平等价值的内涵;网络环境对公平价值的影响很小。因此,网络环境民法主要追求自由、平等、公平、安全、效率等价值理念。

A review of representation issues and modeling challenges with influence diagrams

Since their introduction in the mid 1970s, influence diagrams have become a de facto standard for representing Bayesian decision problems. The need to represent complex problems has led to extensions of the influence diagram methodology designed to increase the ability to represent complex problems. In this paper, we review the representation issues and modeling challenges associated with influence diagrams. In particular, we look at the representation of asymmetric decision problems including conditional distribution trees, sequential decision diagrams, and sequential valuation networks. We also examine the issue of representing the sequence of decision and chance variables, and how it is done in unconstrained influence diagrams, sequential valuation networks, and sequential influence diagrams. We also discuss the use of continuous chance and decision variables, including continuous conditionally deterministic variables. Finally, we discuss some of the modeling challenges faced in representing decision problems in practice and some software that is currently available.     

企业内部服务质量、关系质量对内部顾客忠诚的影响机制:基于内部营销视角的实证研究

本文基于内部营销视角,揭示内部服务质量的各个组成因素之间的关系以及内部服务质量对关系质量的影响,进而探索内部服务质量、关系质量对内部顾客忠诚的影响机制。通过对某电信企业内部238份员工样本的采集分析,提出并验证内部服务质量(含实体环境质量、交互质量和结果质量)、关系质量(含内部顾客信任、满意)对内部顾客忠诚的影响机制整合模型。研究发现,内部服务质量的三个维度之间确实存在层级叠加作用,而服务质量则会通过信任这一中介变量影响内部顾客的满意、承诺。内部关系质量的三因素中,内部顾客的承诺水平对内部顾客的忠诚度有直接正向影响,提高对内部顾客的承诺水平是提高内部顾客忠诚度的关键。     

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.     

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.
