论设计中的符号学运用

基于对符号学理论的把握,对设计中符号的运用进行分析与探讨。设计中符号一般具有可识、通适、限制和特殊的特点。同时,设计手法中的符号使用也可分为象征、相关、相似等三种形式。总之,对符号学的研究有助于设计师在处理人、作品与环境之间关系的同时较好地完成设计过程。     

Robust testing with generalized partial linear models for longitudinal data

By approximating the nonparametric component using a regression spline in generalized partial linear models (GPLM), robust generalized estimating equations (GEE), involving bounded score function and leverage-based weighting function, can be used to estimate the regression parameters in GPLM robustly for longitudinal data or clustered data. In this paper, score test statistics are proposed for testing the regression parameters with robustness, and their asymptotic distributions under the null hypothesis and a class of local alternative hypotheses are studied. The proposed score tests reply on the estimation of a smaller model without the testing parameters involved, and perform well in the simulation studies and real data analysis conducted in this paper.     

Quadratic estimators of covariance components in a multivariate mixed linear model

It is known that the Henderson Method III (Biometrics 9:226–252, 1953) is of special interest for the mixed linear models because the estimators of the variance components are unaffected by the parameters of the fixed factor (or factors). This article deals with generalizations and minor extensions of the results obtained for the univariate linear models. A MANOVA mixed model is presented in a convenient form and the covariance components estimators are given on finite dimensional linear spaces. The results use both the usual parametric representations and the coordinate-free approach of Kruskal (Ann Math Statist 39:70–75, 1968) and Eaton (Ann Math Statist 41:528–538, 1970). The normal equations are generalized and it is given a necessary and sufficient condition for the existence of quadratic unbiased estimators for covariance components in the considered model.     

Local influence in multilevel models

The authors study the local influence of observations in multilevel regression models. To this end, they perturb simultaneously the variances, responses and design matrix. To measure the local change caused by these perturbations, they use generalized Cook statistics for the fixed and random parameter estimates. Closed form local influence measures also allow them to assess the joint influence of various observations. They suggest a simple computation method and illustrate their results using two examples.

基于经营者薪酬设计的中小国企改制研究

通过研究经营者薪酬设计在企业改制过程中的短期效用和长期效用,提出国有企业,特别是中小国企的改制新思路:通过实行期股制,使国有股逐步退出,从而实现经营者控股的渐进式管理层收购.     

非物质社会的互动式设计研究

工业社会的物质文明向信息社会的非物质文明的转变,在一定程度上导致设计模式从单向的输出状态转化为双向的互动沟通。互动式设计不再以某种具有确定功能的产品作为创作的目的,而是以创建一个可供使用者自由选择和发展的平台为依归。它所创造的体验具有多感官化、虚拟化、动态化、超现实化的特征。
