参古定 望今制奇－评刘锡庆的写作理论

刘锡庆对现代写作学的理论贡献是多方面的,从基础理论到文体认,纵教学论到史论,都有建树,尤其在基础理论方面,他用力最勤,成就最大,他“望今制奇,参古定法”,把“以文为本”的传统文章学转换为“以写为中心”的现代写作学。     

高校大学生MOOC持续使用行为研究——基于ECM-ISC和承诺信任理论

新型冠状病毒疫情为MOOC平台带来的机遇,但也面临如何继续留住用户的挑战。厘清高校大学生用户MOOC持续使用行为的影响因素,对MOOC平台优化服务、提升用户体验具有重要意义。本文基于ECM-ISC模型,结合考虑交互关系的承诺信任理论模型,对高校大学生MOOC持续学习行为的因素及各因素之间的关系进行了实证分析。研究结果表明:内在动机是学习者满意度的主要影响因素;信任是用户持续使用MOOC平台的重要影响因素;引入信任和承诺后的用户持续使用行为模型具有更强的解释力;信任与承诺在满意度对用户持续使用的正向影响中起到部分中介和链式中介作用。

Differences of math anxiety groups based on two measurements,MASS and EEG

This article investigated how mathematic anxiety (MA) of Korean middle school students could be reduced by comparing analytically their cognitive neuroscience and questionnaire results. We developed a three-hour Complex Treatment Program (CTP) on quadratic functions for the study. In the summer of 2016, we collected data of the pre and post MA questionnaires by Mathematics Anxiety Scale for Students (MASS), the percent of correct answers (PCA) and reaction time (RT) by E-prime program, and also brain-imaging data of the event related potentials (ERP) by Electroencephalograph (EEG) using computer-based functional F-G model. The result indicated the CTP to be effective with the group with higher math anxiety and the group with higher achievement respectively. The MASS result was verified with the better performance of PCA on type G, which was measured by E-prime program. Some interesting patterns were revealed on brain-imaging data by EEG, indicating more brain activities with the MA groups.     

出口退税、企业生产率与我国出口企业“生产率悖论”研究

Melitz的异质性企业贸易理论认为企业的出口行为是由企业的生产率和沉没成本相互作用而内生决定的。拟从出口退税视角出发,研究出口退税对企业生产率和沉没成本的影响。研究表明,出口退税可以帮助企业克服进入国际市场的沉没成本,降低出口企业临界生产率,使出口企业丧失提高生产率的动力,最后导致出口企业总体平均生产率低于内销企业,出现“生产率悖论”问题。     

社会共生理论与社会阶层流动研究

社会共生理论起源于德国生物学家提出的生物学概念"共生",上世纪90年代胡守均教授在此基础上提出了"社会共生论",并把它发展为的一种社会哲学。当前中国社会处于社会转型期,社会阶层分化流动,社会问题频发,为了化解社会问题,必须倡导社会共生论,促进社会和谐发展。     

变易理论在大学数学课堂教学中照顾学习差异的启示

变易理论指出,要正确认识某事物,就应该分离出该事物的关键特征,运用变易图式加以对比,可以有效达到对关键属性的辨析。以"变易理论"作为大学数学教学设计的理论指导,可以有效改善教与学,照顾学习差异帮助学生掌握学习内容,有利于教学质量的提高。     

Modular designs and integrating practices: Managing collaboration through coordination and cooperation

Collaboration in large-scale projects introduces challenges involving both coordination (the ability to collaborate) as well as cooperation (the willingness to do so). Existing research has shown how modular designs can improve coordination by locating interdependencies within rather than between different modules. Based on an in-depth case study of collaboration in a large-scale infrastructure project, our study highlights an effect of modularity on collaboration that previously has been overlooked. Specifically, we show that while modular designs may help overcome coordination challenges by reducing interdependencies between modules, they can in turn hamper collaboration by emphasizing specialization within modules. Therefore, though existing work typically perceives modularity and integration as opposites, we clarify how they can also act as complements. In particular, we show how firms need to complement modular designs with integrating practices that stimulate cooperation. Overall, we contribute to the literature on collaboration and modularity by explaining when and how organizations can combine modularity and integration.
