反映在结构因素、关系因素和认知因素三个维度上的高管团队内部社会资本为决策信息的交换和共享提供了机会、意愿和能力,有利于团队内部形成建设性的冲突模式,促进决策效果的提高.本文以团队冲突为中介变量,建立了高管团队内部社会资本与决策效果的关系的理论框架,提出了研究命题,并对企业高管团队内部社会资本的培育提出建议.     

固定效应部分线性变系数面板模型的快速有效估计

本文将最小二乘支持向量机(LSSVM) 和二次推断函数法(QIF) 相结合，为个体内具有相关结构的固定效应部分线性变系数面板模型提供了一种新的快速估计方法；在一定的正则条件下，论证了参数估计量的渐近正态性和非参数估计量的收敛速度；采用Monte Carlo模拟考察了估计方法在有限样本下的表现并将估计技术应用于现实数据分析。该方法不仅保证了估计的有效性和统计推断力，而且程序运行速度得到较大幅度提升。     

语境理论对语篇内词汇理解的作用

词汇在英语学习中居于非常重要的地位,它对于英语水平的提高有着不可估量的作用。而语境对于理解词汇所起的作用是不容忽视的。在英语学习过程中,许多人对词汇理解的效果并不理想,主要原因就是忽略了语境在词汇理解中所起的作用。在这样的背景下,越来越多的语言学家认识到语境的重要性,尤其是语境理论对于词汇理解的指导意义和研究价值。从关联理论的角度出发,分析了语境理论对语篇中词汇理解的作用。

外语教师课堂话语标记语语用功能考究

话语标记语是外语教师课堂话语中颇为常见的语言现象,具有十分重要的话语功能。以认知语用学为理据,结合自然的教师课堂话语语料,分析了外语教师课堂话语标记语的语用功能,揭示出课堂话语标记语不但是课堂教学中语篇组织的语言机制,而且是教学过程中动态顺应策略的显性依据。同时,研究结果对外语教师课堂话语标记语的合理使用,教学效果的优化也有所启示。     

Contextual influence on evaluation capacity building in a rapidly changing environment under new governmental policies

Evaluation capacity building (ECB) is a context-dependent process. Contextual factors affecting ECB implementation have been explored theoretically and practically, but their influence within a changing environment has seldom been discussed. This study examined essential context-sensitive parameters, particularly those involved in implementing new governmental policies regarding higher education. Taiwan was used as a case study for exploring the effect of contextual change on ECB attributes from the perspectives of training receivers and providers. Surveys and interviews were used for data collection and importance–performance analysis was applied for data analysis. Four prominent features were identified. First, the ECB attributes perceived as important by receivers were performed adequately, whereas those perceived as less important were performed less well. Second, under new policies, training provider designed training covering a wide range of ECB, whereas receivers focused on those can be directly applied in evaluation process. Third, in a small education system such as Taiwan’s, the complexity of peer review is high and ethical issues become important. Fourth, because the evaluation structure has been changed from single- to dual-track, receivers expect more training for institution staff, whereas providers insist on hierarchical training. Aligning ECB supply and needs is paramount for adaptation to new policies.     

ICT投资、互联网普及和全要素生产率

本文使用DEA-Malmquist指数方法对2002-2012年我国分行业全要素生产率、技术效率与技术进步进行测算,并基于我国地区投入产出表构建了ICT资本投入强度。在此基础上,本文就ICT投资对生产率的影响进行了实证检验。研究发现,ICT投资对全要素生产率提升具有积极作用,并且主要通过ICT投资促进技术效率提升实现。面板门限回归模型的结果显示,只有达到一定互联网普及率时,ICT投资促进技术效率提升的作用才显现,并在高互联网普及率时进一步增强;但在高互联网普及率下,ICT 投资对技术进步存在抑制作用,在全要素生产率层面表现为ICT 投资的促进作用消失。因此,现实的ICT 投资应重视通过信息化管理提升行业资源的有效利用能力,以最大化技术效率对全要素生产率的贡献;应充分考虑不同行业和地区的互联网普及程度,以深度激发“连接经济”对于释放ICT效能的互补性作用;还应注意配套相应产业政策,以减轻互联网发展对技术进步的阻碍作用。     

The typification of Hispanics as criminals and support for punitive crime control policies

The Hispanic population is now the largest and fastest growing minority in the United States, so it is not surprising that ethnic threat linked to Hispanics has been associated with harsher crime control. While minority threat research has found that individuals who associate blacks with crime are more likely to support harsh criminal policies, the possibility that this relationship exists for those who typify Hispanics as criminal has yet to be examined. Using a national random sample, this study is the first to use HLM to find that perceptions of Hispanics as criminals do increase support for punitive crime control measures, controlling for various individual and state influences. Moderated and contextual analyses indicate this relationship is most applicable for individuals who are less apt to typify criminals as black, less prejudiced, less fearful of victimization, politically liberal or moderate, not parents, and living in states with relatively fewer Latin American immigrants.     

论大学英语课堂评估方式及其对教学的反拨作用

适时、适量、适度的大学英语课堂评估能有效地促进大学英语教学.大学英语课堂评估的形式可分为测试性与非测试性两类,非测试性方式有课堂观察、学习档案、日志等,在当前比较注重学生英语运用能力的教学中,非测试手段尤为重要.在测试性方式中,随堂测试、诊断测试、成绩测试等都可选用.如果进行得恰当,课堂评估对教学会产生多方面的积极反拨作用.     

学生授课PK法在大学课堂教学中的运用

大学课堂大多以教师讲授为主,很难听到学生的观点与异议,学生的主动性与积极性难以激发,学习效果受到严重影响。本文提出一种提高大学课堂学习效果的学生授课PK法,这种方法将改变教师一贯唱主角的教学模式,同时提高学生参与学习的主动性、积极性。
