关于英语教学目标的几点思考

学习英语的最终目标是达到听、说、读、写四项基本技能的熟练掌握与运用。如何达到这个目标,英语教学者们从不同的角度阐述了各自不同的观点。那么在学习英语的过程中,究竟应当优先发展哪一个目标呢?本文就口语与书面语,表达能力与理解能力这两对技能的优先发展问题进行论述,并且提出了学习英语四项基本技能的最佳目标及策略———即根据具体情况,从实际出发,充分调动学生和教师的主动性和互助性,达到听、说、读、写的完美统一。     

THE PARTICIPATION DIVIDE: Content creation and sharing in the digital age

This paper looks at the prevalence of creative activity and sharing in an age when the barriers to disseminating material have been considerably lowered compared with earlier times. The authors use unique data to explore the extent to which young adults create video, music, writing and artistic photography, as well as the prevalence of sharing such material online. Findings suggest that despite new opportunities to engage in such distribution of content, relatively few people are taking advantage of these recent developments. Moreover, neither creation nor sharing is randomly distributed among a diverse group of young adults. Consistent with existing literature, creative activity is related to a person's socioeconomic status as measured by parental schooling. The novel act of sharing online, however, is considerably different by gender with men much more likely to engage in it. However, once internet user skill is controlled for, men and women are equally likely to post their materials on the Web.     

批判性思维和非形式逻辑的互动关系

20世纪后期,北美教育领域出现了强调思维能力和气质,克服低层次、复制性学习弊端的“批判性思维运动”。几乎同时,一股逻辑学的“新浪潮”———“非形式逻辑运动”在高校兴起,结果使批判性思维能力和气质的培养成为高校非形式逻辑教育的目标,而非形式逻辑教学成为批判性思维能力和气质培养的主要途径。二者的互动,给高校逻辑教学带来新气象。     

浅谈《战国策》的论理技巧与语言艺术

《战国策》为文铺排渲染,辩丽恣肆,陈说事理纵横捭阖,体情状物酣畅淋漓,堪称先秦史家之文中的出类拔萃之作。在论理技巧方面,《战国策》的文章大都善于分析形势,指陈利害,好设机巧,引人入彀,诱敌就范,进退有据,擒纵自如,具有极强的说服力和感染力。就语言而论,《战国策》之文大都放言无惮,绝少掩饰,文辞铺张扬厉,气势恢宏,且又精炼传神,形象生动,富于华彩,其语言艺术的精熟富丽,也大大超过了先秦其它几部历史散文。     

Fit and Skill in Employee Selection: Insights from a Study of Headhunters

We draw upon evidence from a qualitative study of headhunters to provide insights into the character and importance of candidate fit and skill for the selection of a broad range of white-collar employees. Headhunters suggest that the fit of a job candidate is assessed at two levels, one corresponding with a general compatibility with organization-level norms, culture, and strategy, the other corresponding more closely with traits and characteristics of the person or persons with whom the job candidate actually interviews. Skill—a factor which is largely neglected by those who tout the importance of fit—also plays an important and independent role in employee selection. Stalls that influence the selection of employees from a pool of candidates tend to be highly specific if not idiosyncratic, and take the form of what headhunters call hot buttons. We conclude by discussing the conceptualization, causes, and implications of fit; we also consider how the importance of fit and hot buttons challenges the explanatory logic of standard accounts of labor-market success.     

On the shrinkage of local linear curve estimators

Local linear curve estimators are typically constructed using a compactly supported kernel, which minimizes edge effects and (in the case of the Epanechnikov kernel) optimizes asymptotic performance in a mean square sense. The use of compactly supported kernels can produce numerical problems, however. A common remedy is ridging, which may be viewed as shrinkage of the local linear estimator towards the origin. In this paper we propose a general form of shrinkage, and suggest that, in practice, shrinkage be towards a proper curve estimator. For the latter we propose a local linear estimator based on an infinitely supported kernel. This approach is resistant against selection of too large a shrinkage parameter, which can impair performance when shrinkage is towards the origin. It also removes problems of numerical instability resulting from using a compactly supported kernel, and enjoys very good mean squared error properties.     

管理技能的因子分析及其对绩效影响的实证研究

本文以在沪三资企业中12家电子制造企业管理人员的有效问卷271份为第一手资料,用因子分析等方法分析了构成这些人员管理技能的四大要素为:领导与激励技能、计划组织与协调技能、决策与创新技能、控制与授权技能;研究的结果表明,并非每项管理技能对提升企业的绩效都起同样的作用。不同绩效企业的管理者对各种管理技能的运用程度是有所不同的。
