虚拟微语境差异与机构话语的语用策略运用

面对面交流中,机构话语的语用策略运用比较稳定,然而在虚拟语境下却发生了变化。其中,交互轮次的显著差异构成了两种不同氛围的微环境。本文以医患对话中患者首轮咨询使用的语用策略为研究对象,采用定量分析的手段对比了八种策略在不同微环境中的使用差异。结果显示三种积极礼貌策略和两种消极礼貌策略呈现出显著差异,而另外两种消极礼貌策略和一种非礼貌语用策略则没有达到显著性水平。以上结论为进一步开展虚拟语境定量话语分析提供了借鉴。     

浅谈高等数学教学

对高等数学的教学方法进行探讨,从以下四个方面结合实例进行阐述：1）重视数学概念、符号教学,提醒学生勿要望文生义;2）重视传统教学技巧的教学,培养学生的数学能力;3）深度钻研教材,化解学生的困惑;4）利用数学学科分支知识渗透教学,培养学生学习兴趣.     

作家性格与作家创作关系新探——从该问题所涉的相关中国文化语境出发

作家性格单线、直线决定创作表征的认识,与"性格决定命运"之庸俗的中国"大众日常意识"共谋。中国社会语境往往铸就了国人机械、被动顺应社会的性格。粗俗的唯物主义哲学、中国文化结构特有的"身体化"特性,进一步强化了我们从生理、遗传之浅见来理解性格。事实上,中国人性格极具"面具化"特征。它们是生活环境超常挤压的创伤之果。根本还在于,作家可以虚拟创作性格,其思想、价值观念往往影响了艺术取向。另外,现代人格学说较之传统性格论有更合理的知识谱系。

IT engagement as a blessing and a curse? Examining its antecedents and outcomes in organizations

Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT engagement by drawing on the collective expectations for IT use. In particular, we examined the extent to which normative pressure on IT use drives users’ information load and IT engagement. Finally, we sought to understand whether users’ attempts to avert dependency on IT use reduced their IT engagement. Several hypotheses were developed and tested with survey data of 1091 organizational IT users. The findings help explain the role of normative pressure as a key driver of IT engagement and validate the positive and negative outcomes of IT engagement in organizations.     

Offering Adequate Pedagogical Progression via Mobile Equipments—— Experiment of a French Engineering School

Students may enter our 5-year engineering school in France at two levels ： first and third year. However, due to their quite different backgrounds （ this is especially true for third year students ）, we need to provide newcomers with a 6-week training period during which they follow classes in the fields where they particularly feel weak. Unfortunately, depending on the student＇s background, this is not always possible to bring him/her to the expected level. Another aspect one needs to mention is that these students may not have the same weaknesses in a given field. However, for economical reasons, those classes follow a uniform program as it is not feasible to provide a customized progression. In this paper we discuss how to redesign a mathematics course so as to offer tailored exercise sequencing. Groups of 20 students could then draw their exercises from an intranet database according to their previously completed work, try to solve it by themselves, request additional hints and even ask for some direct help from the teacher. Such a database is currently under development. If it turns out several students stumble against the same difficulty the teacher could show the whole class room how to solve it using the digital projector. This project goes one step further than our initial mobile education project （ 2003 - 2004 ）. Until recently, we had used the equipment in a unique direction, from the instructor toward the students. Here, in this new project we are focusing on the whole loop in order to offer a more adequate （personalized） pedagogical progression ： from the student to the teacher （when the tablet PCs are monitored by the teacher）, and back toward the students （when a direct help is provided by the teacher）.     

基于情境感知的电商平台推荐系统框架研究

[目的/意义]随着互联网行业的蓬勃发展,电商平台的用户与商品数量均呈现井喷增长。这一趋势在促进互联网经济发展的同时也为用户带来了"信息过载"的问题。电商平台如何从用户的历史行为日志中获取信息,并根据用户当前情境推荐商品,不仅是重要的理论与技术课题,同时也蕴藏着巨大的商业价值。[方法/过程]文章结合情境感知技术,提出了一种五层推荐系统框架,自底向上分为:感知层、过滤层、排序层、规则层和应用层。同时,利用淘宝APP的购物数据进行了模拟推荐实验,比较了各层次不同设计方式的推荐效果。[结果/结论]研究发现,融入了情境感知技术的推荐系统框架可以显著提高推荐的精确率,但是会削弱召回率。基于此,为电商平台提出了部分建议。     

基于目标框架的信息系统安全提示遵从意愿研究

为确定在使用信息系统进行操作决策的过程中,用户对何种目标框架的安全提示更为遵从,在对安全提示情境进行界定和分类的基础上,以系统用户为对象,设计E-prime情境实验并运用后测问卷分析方法,采用“接收刺激—大脑反应—动作响应”（S—O—R）模式分析用户从接受刺激到作出反应的全过程,研究不同目标框架下用户遵从意愿的差异性。研究发现：较之于负性目标框架,正性目标框架的安全提示更能增强用户的遵从意愿,且不同性别用户在正性目标框架下的遵从意愿程度不同;而在不同学历水平的个体差异下,框架效应的作用无差异。基于此,提出根据用户的性别差异设计不同信息描述的安全提示,同时保证内容表述的可理解性和可遵从性等对策建议,以促进信息系统安全提示完善、增强用户的遵从意愿。     

书话批评论

以书话为体行批评之事,这一做法兴于上个世纪初,今日又有大盛之势.书话中的批评是作者有意为之的,它在概念选择、修辞使用、语言阐述、结构安排以及把握文本的方式上已形成自己的特点,而且,中国当下的语境适宜于书话批评的存在.但是,作为一种非主流批评话语方式,书话中的批评呼唤理性的约束.
