Horwitz's rule, transforming both sides and the design of experiments for mechanistic models

Summary. The paper develops methods for the design of experiments for mechanistic models when the response must be transformed to achieve symmetry and constant variance. The power transformation that is used is partially justified by a rule in analytical chemistry. Because of the nature of the relationship between the response and the mechanistic model, it is necessary to transform both sides of the model. Expressions are given for the parameter sensitivities in the transformed model and examples are given of optimum designs, not only for single-response models, but also for experiments in which multivariate responses are measured and for experiments in which the model is defined by a set of differential equations which cannot be solved analytically. The extension to designs for checking models is discussed.

论英语语感能力的培养

英语语感是对遵循或背离英语既定用法的敏感性,语感的培养对促进英语学习起着重要作用。培养语感的过程可分为三个阶段:(1)模仿语音语调,打好语感基础;(2)朗读背诵听说,逐步培养语感;(3)阅读写作分析,提高语感层次。     

中国FDI进入模式的影响因素

本文综合交易费用理论和谈判力量理论分析框架,探讨了FDI进入中国市场模式(合资／独资)的影响因素。应用两分Logit模型进行实证分析,结果显示区位因素、来源地因素、投资项目的经营期限以及投资规模都对FDI进入中国市场模式产生了重要的影响,而产业因素的影响则统计不显著。     

高校体育社团社会责任对成员组织公民行为的影响——心理契约、组织认同的序列中介作用

为考察高校体育社团社会责任对社团成员组织公民行为的影响,以及心理契约和组织认同在它们之间的多重中介作用,采用问卷法对高校体育社团成员进行调查的结果发现:高校体育社团社会责任能够正向预测组织公民行为,心理契约与组织认同在社会责任与组织公民行为中间起中介作用。高校体育社团社会责任通过4条路径影响组织公民行为:直接作用,心理契约、组织认同的中介作用,心理契约和组织认同的序列中介作用。构建的多重中介模型在一定程度上解释了高校体育社团社会责任对社团成员组织公民行为的影响机制。研究结果表明,高校体育社团重视社会责任有助于提高社团成员心理契约和组织认同,进而提高社团成员组织公民行为。     

Semi-polynomial copulas

In this paper, we characterise a family of bivariate copulas whose sections between the main diagonal and the border of the unit square are polynomial, generalising several families of copulas, including those with quadratic and cubic sections. We also study a measure of association and the tail dependence for this class, illustrating our results with several examples.     

公司章程自治价值分析

理论上,公司章程是公司的"宪章",形式上公司章程是公司进行登记、取得公司资格的不可或缺性要件,而实际上,在我国,公司章程并未完全发挥其应有的作用,面临着尴尬的处境。本文首先介绍了自治价值在公司章程中的体现,然后对公司章程现状进行剖析,并提出实现公司章程自治价值的可行性办法。     

Twenty-First Century Lesbian Studies,edited by Noreen Giffney and Katherine O'Donnell

Using a convenience sample of 157 undergraduates, this study explored the likeability ratings of target characters from selected film clips who were described as gay or heterosexual as they associated with a gay-described foil character (i.e., a character against which the target is compared). As predicted, male respondents who strongly endorsed anti-gay prejudice viewed gay-described targets more favorably than heterosexual-described targets when each target was paired with a gay foil. Further, this pattern of biased ratings by high-prejudice male participants against our heterosexual target differentiated these participants from both low-prejudice male and high-prejudice female respondents. In contrast, but as hypothesized, high-prejudice female respondents compared to high-prejudice males rated heterosexual-described targets more favorably than they rated gay-described targets.     

文化差异视角下的英汉颜色词的联想

不同的民族由于地理、民俗、宗教及价值观念等方面的差异,在表达同一概念时,词汇被赋予了许多的联想意义。掌握汉英颜色词不同的文化联想意蕴,并且了解产生这些不同联想意义的原因不仅有利于提高英语学习水平,还能促进和加强中西文化之间的交流。
