英语颜色词习语特征、趣味性及新用

习语是语言的一个组成部分,又是语言的载体,语言学习不能独立于习语学习之外,英语是一门快速发展的语言,在其不断发展过程中,积累了大量的习语,特别是大量的英语颜色词习语,是英语中值得注意的一种文化现象。从颜色词习语的结构及其句法功能,修辞特征及其表达的心理特征等四个方面对英语中的色彩词习语进行研究,可了解其常见的四种结构及功能、所具有的修辞特征和心理特征。     

21世纪我国学校美育的操作设计

面向21世纪的学校美育课程应是一组课群,而不是一门课程.这些课群贯穿在学校教育的全过程(从小学至大学).它既包括学校教育的主渠道,又包括学校第二课堂;它既包括活动类课程、赏析类课程,又包括理论类课程和渗透类课程;它的内容既涉及到不同民族、不同文化、不同类型的人类艺术经典作品,涉及到青少年的艺术能力培养,又涉及到美学、美育、艺术史、艺术批评、审美文化等基本知识.小学阶段美育课群的目标设置为感性教育(敏锐感知,激发情感与想象);中学阶段美育课群的目标设置为趣味教育(在审美赏析中形成健康高尚的审美情趣);大学阶段美育课群的目标设置为人格教育(感性与理性的统一,塑造健康人格).     

提升城市文化形象的对策分析——基于广州实践的若干思考

在城市的国际化竞争越来越激烈的背景下,关注文化建设和发展、关注文化形象和文化品位的提升更应当成为城市政府的理性自觉。在广州的快速发展过程中,如何建成"新岭南文化中心"成为广州当下发展无法回避的问题。为此,应从走向现代化和国际化的双重维度来审视并制定广州的文化发展策略,着眼于推进以岭南文化为底色与特质的城市文化新发展,来提升建设世界文化名城要求相适应的城市文化形象。     

论苏东波词的情思品位

东波词新变的实质是对词的审美品位的提升,而东坡提高词品的本质方面,是对词的情思品位的提升.他不仅拓宽了词的表情领域,扩大了词的情感容量,而且更重要的是写出了情感的质量和品格.他以深刻的情感内蕴、博大的情感气度、清旷的情感格调以及高卓的情感智慧,为词体更好地发挥抒情功能指出了"向上一路".东坡词在审美品位上的独立高标,为词体文学地位的提高做出了重要贡献.

Bathtub distributions: a review

Bathtub distributions are characterized by bathtub failure rate functions . These are possibly more realisitic models than the monotone failure rate models . A systematic account of such distributions is not available and this review aims to give such an account . We give some easily verifiable conditions to check the bathtub property of a distribution along with methods to construct such distributions . We also discuss some stochastic and reliablity mechanisms which lead to bathtub distributions. These include mixtures ( stochastic failure rate models ) , series system , stochastic differential equation models and so on. We also review inference on bathtub distributions. The paper concludes with a rather exhaustive list of bathtub distributions.     

Robust methods of estimation of regression coefficients 1

Recently, cumulative residual entropy (CRE) has been found to be a new measure of information that parallels Shannon's entropy (see Rao et al. [Cumulative residual entropy: A new measure of information, IEEE Trans. Inform. Theory. 50(6) (2004), pp. 1220–1228] and Asadi and Zohrevand [On the dynamic cumulative residual entropy, J. Stat. Plann. Inference 137 (2007), pp. 1931–1941]). Motivated by this finding, in this paper, we introduce a generalized measure of it, namely cumulative residual Renyi's entropy, and study its properties. We also examine it in relation to some applied problems such as weighted and equilibrium models. Finally, we extend this measure into the bivariate set-up and prove certain characterizing relationships to identify different bivariate lifetime models.     

Two ways of modelling overdispersion in non-normal data

For non-normal data assumed to have distributions, such as the Poisson distribution, which have an a priori dispersion parameter, there are two ways of modelling overdispersion: by a quasi-likelihood approach or with a random-effect model. The two approaches yield different variance functions for the response, which may be distinguishable if adequate data are available. The epilepsy data of Thall and Vail and the fabric data of Bissell are used to exemplify the ideas.     

Diagnostic tools in generalized Weibull linear regression models

We propose some statistical tools for diagnosing the class of generalized Weibull linear regression models [A.A. Prudente and G.M. Cordeiro, Generalized Weibull linear models, Comm. Statist. Theory Methods 39 (2010), pp. 3739–3755]. This class of models is an alternative means of analysing positive, continuous and skewed data and, due to its statistical properties, is very competitive with gamma regression models. First, we show that the Weibull model induces ma-ximum likelihood estimators asymptotically more efficient than the gamma model. Standardized residuals are defined, and their statistical properties are examined empirically. Some measures are derived based on the case-deletion model, including the generalized Cook's distance and measures for identifying influential observations on partial F-tests. The results of a simulation study conducted to assess behaviour of the global influence approach are also presented. Further, we perform a local influence analysis under the case-weights, response and explanatory variables perturbation schemes. The Weibull, gamma and other Weibull-type regression models are fitted into three data sets to illustrate the proposed diagnostic tools. Statistical analyses indicate that the Weibull model fitted into these data yields better fits than other common alternative models.     

Optimal repeated measurements designs for comparing test treatments with a control

A-optimal and mv optimal repeated measurments designs for comparing serveral test treatments with a control are considered. the models considered are basically of two types: without preperides and the cirular model. It is shown known that some known strongly balanced uniform repeated measurements designs can be modified to obtain optimal designs for this problem. Some other methods of finding optimal designs are also given.
