四川环境污染与经济增长的计量分析

环境与经济的关系问题一直是人们关注的焦点。本文通过建立经济增长与环境污染之间的计量模型,运用计量经济方法分析了四川经济增长与环境污染之间的关系及其冲击效应,证实了环境库兹涅茨曲线在四川并不存在。因此,在环境保护和改善方面,政府应发挥积极的作用,即通过制定产业政策、经济结构调整政策和环境改善政策,加强对环境污染项目或企业的控制和环境污染排放的监督检查,促进经济增长方式的转变,实现经济与环境的协调发展。     

The perspective of six Malaysian students on playing video games： Beneficial or detrimental？

This study provides a glimpse into understanding the potential benefits as well as harm of playing video games from the perspective of six Malaysian secondary school students, aged 16-17 years old. The rationale of the study is to enable parents, educators, administrators and policy makers to develop a sound understanding on the impact of playing video games before making any judgment on the contemporary youth culture. Thus, further decision on the acceptance of video games as a new innovation in school or at home could be considered. Although this study is not very extensive, the findings suggest that playing video games contributes to cognitive, social, motivational and emotional development. However, potential harms do exist. Parents play an important role in guiding their children either directly or indirectly, as indicated by the respective students. Caution is advised in the interpretation of the study＇s findings as it is solely based on the perspectives of the students, as the first person＇s views. Nevertheless, each student has their very own perspective on the impact of video games on them.     

结合交际教学法提高高职英语课堂教学效果

以培养学生交际能力为教学目标是交际教学法的本质,也是高职英语课程教学的基本要求。教师如果能在高职英语课堂教学实践中充分发挥交际教学法的优点,针对学生的具体情况,制定出切实可行的教学计划,选用合适的教学材料,并有效地组织课堂教学活动,无疑将使课堂教学效果得到很大程度的提高。     

关于英语词汇测试中提供语境因素的思考

本文探讨了语境因素在英语词汇测试中的重要性,从掌握词汇的标准出发,对比了离散性方法和综合型方法的反拨作用,及反映在信度和效度上的矛盾.在此基础上,本文分析了语境在词汇测试中的作用,并介绍了两种尝试将语境和词汇有机结合的方法.     

文章标记对英语语篇信息理解与保持的影响

本研究采用2（语篇难度）×3（文章标记类型）的实验设计,研究了文章标记对英语语篇信息理解与保持的影响。结果表明：（1）文章标记对英语语篇信息理解和保持主效应显著;（2）文章标记与英语语篇难度之间存在显著的交互作用。英语语篇容易时。标记效应不显著;英语语篇较难时,标记效应显著;（3）当阅读材料较难时,全标记条件下,被试在英语语篇信息理解和保持方面得分最高;无标记次之;半标记最低。本研究同时也给出了一些英语阅读教学启示。     

“动词＋死”结构的语用和语义变化初探

“动词＋死”结构词性转换后会产生特殊的语用效果,引起一系列的语用和语义变化,如搭配范围和上、下义,主一被动转换和主语特征,否定特征和标记词等。对于这些问题的探讨有着现实的意义。     

从教育规律看高等教育的文化功能

教育规律包括外部规律和内部规律。教育外部关系规律是指“教育必须与社会发展相适应”。它制约着教育的社会功能,包括政治、经济、文化等方面的功能;教育内部关系规律是指德、智、体、美等诸因素之间的关系。它制约着教育的育人功能。文章以教育规律为切人点,对高等教育的文化功能进行了探讨。论证了高等教育在教育规律的驱使下,从社会功能和育人功能两个方面,通过文化创新、文化传承等途径对文化发展起着巨大的促进作用。     

Eccentricity and thermoviscous effects on ultrasonic scattering from a liquid-coated fluid cylinder

Calculation of the scattered field of the eccentric scatterers is an old problem with numerous applications. This study considers the interaction of a plane compressional sound wave with a liquid-encapsulated thermoviscous fluid cylinder submerged in an unbounded viscous thermally conducting medium. The translational addition theorem for cylindrical wave functions, the appropriate wave field expansions and the pertinent boundary conditions are employed to develop a closed-form solution in the form of infinite series. The analytical results are illustrated with a numerical example in which the compound cylinder is insonified by a plane sound wave at selected angles of incidence in a wide range of dimensionless frequencies. The backscattered far-field acoustic pressure amplitude and the spatial distribution of the total acoustic pressure in the vicinity of the cylinder are evaluated and discussed for representative values of the parameters characterizing the system. The effects of incident wave frequency, angle of incidence, fluid thermoviscosity, core eccentricity and size are thoroughly examined. Limiting case involving an ideal compressible liquid-coated cylinder is considered and fair agreement with a well-known solution is established.     

依托校园网扩展高校档案教育作用之思考

高校档案是高校历史发展的结晶,是学校各方面工作的长期积累,是取之不尽、用之不竭的教育源泉。目前高校已具备了采用数字化手段生成电子档案,进行网络监控和自动化接受,实现信息服务网络化的条件。利用校园网络来扩展高校档案教育作用,是可行的和必要的,值得我们去研究和实践。     

论精神分析在大学生心理咨询中的作用

在大学生心理咨询工作中,精神分析是一种可供采用的方法。精神分析可以丰富大学生心理咨询理论,并且,其基于自由联想法的临床治疗技术如对移情的处理、恰当干预与合理阐释等等,一方面比较适合当代大学生的心理实际,另一方面,也能起到很好的临床治疗作用。
