多媒体英语教学的一点思考

进入21世纪以来，人们越来越重视英语教学。如何提高高职高专英语教学的效率，如何改进传统的英语教学法，如何改变一支粉笔、一本书、一块黑板、一张嘴的教学模式，如何创新英语教学，将现代化的多媒体教学手段引进英语教学，并且在使用多媒体教学过程中，如何扬长避短，本文对上述问题将做出回答，提出作者对多媒体英语教学的一点思考。     

The Three Tomorrows of Postnormal Times

The Three Tomorrows of Postnormal Times is a new method for foresight and futures researchers and practitioners. Designed and developed to explore the complexity, chaos, and contradictions of postnormal times and what might come next, the three tomorrows method uses a multi-layered approach to situate and analyze trends, emerging issues, and imaginings of the future(s), including complex, horizonspecific forecasts. In this paper, we provide a theoretical overview of the key concepts underlying our approach, including the three forms of ignorance and uncertainty as well as the Menagerie of postnormal potentialities, which we developed as a mechanism for challenging deeply held convictions, illuminating entrenched contradictions, and enlivening novel considerations.     

非中文专业留学生汉语阅读课教学方法初探——以华中农业大学学习农林专业的留学生为例

阅读课是对外汉语教学中的一门基础课,也是一门汉语言技能课。本文从对外汉语阅读教学的发展着手,通过对阅读教学的背景,状况的分析,结合笔者对外国留学生的教学经验,并参阅大量对外汉语阅读教学研究,探讨对外汉语教学中阅读课教学的适用方法,以帮助国内的汉语教学和研究。     

Competing Against Experienced and Inexperienced Players

In certain markets success may depend on how well participants anticipate the behavior of other participants who have varying amounts of experience. Understanding if and how peoples behavior depends on competitors level of experience is important since in most markets participants have varying amounts of experience. Examining data from two new experimental studies similar to the beauty contest game first studied by Nagel (1995), the results indicate that (1) players with no experience behave the same against competitors with and without experience but (2) players quickly learn to condition their behavior on competitors experience level, causing (3) behavior to stop moving toward the equilibrium whenever new players enter the game and (4) experienced players to earn more money than less experienced players. The paper discusses the implications of the results for understanding and modeling behavior in markets in which participants have different amounts of experience.This revised version was published online in May 2005 with corrections to the acknowledgements.     

面向科技智库的科技创新政策监测体系构建研究

科技创新政策研究是科技智库的核心职责之一，科技创新政策监测是开展科技创新政策研究的基本工具和手段，但目前针对科技创新政策监测体系的系统研究却不多。针对科技创新政策研究需求，创新性地以科技创新政策监测体系为研究对象，系统分析科技创新政策监测对象的范畴、科技创新政策监测的主要方法、科技创新政策智能监测的系统功能、科技创新政策监测的产品设计，可为相关科技智库机构开展科技创新政策研究提供一套具备操作性的研究模式，为后续科技创新政策监测研究提供有益借鉴。     

《市场营销学》教学方法初探

市场营销学是一门建立在经济科学、行为科学和现代管理理论基础上的应用科学。市场营销学的特点使其在当今社会的方方面面发挥着重要的作用。如何把这样一门生机盎然的课程讲的充满活力，是本人深思和探索的课题。所以在教学过程中进行了一些探索，本文重点在教学方法上进行了阐述，以期和各位同仁切磋交流。     

美国农业财政补贴政策的经验与启示

美国农业财政补贴政策对美国的农业发展作出了重要贡献。在多年的农业补贴实践中,美国形成了较为完备的农业补贴体系,积累了丰富的经验,值得我们借鉴。但是在有些方面还要结合中国的情况,不断探索适合中国国情的农业补贴制度。

偏差修正的预白化HAC法在平稳过程伪回归中的应用

在传统预白化HAC法存在有限样本偏差的基础上,提出将自回归参数偏差修正法和残差调整法来减少预白化HAC法的偏差,从而降低相互独立的平稳过程之间发生伪回归的概率。通过一系列的蒙特卡罗模拟表明：第一修正的预白化HAC法确实减少了伪回归概率,且自回归参数偏差修正法减少的幅度要比残差调整法要大得多;第二相对于同方差情形而言,存在GARCH类异方差的回归中预白化HAC法具有更低的伪回归概率;第三当数据过程是AR(2)过程时,在持久性相同的情况下预白化HAC法的伪回归概率要低于相应的AR(1)数据过程。但在高于2阶的自回归数据过程的回归中,残差调整的预白化HAC的伪回归概率具有优势。在样本容量较大(T≥500)时自回归参数修正的预白化HAC法的伪回归概率很接近检验水平,但残差调整的预白化HAC法具有微弱的向下检验水平扭曲.     

Determinants of executive compensation in privately held firms

We examine what determines executive compensation in privately held firms. Our study is motivated by the fact that most studies in this area rely on data from publicly traded firms. Further, the few studies that are based on data from privately held firms only examine a limited number of determinants of executive compensation. Our findings indicate that the pay‐to‐performance relation is weak. Board size and ownership concentration are the only corporate governance characteristics that explain variations in executive compensation. Executive characteristics like skills, title and educational attainment all explain variations in executive compensation. Contrary to our expectations, we do not find a stronger pay‐to‐performance relation in firms with better designed bonus plans.
