University,Knowledge and Regional Development: Factors Affecting Knowledge Transfer in a Developing Region

The role of knowledge in the current knowledge economy cannot be overly emphasised. Successful regions are continuously being linked to excellence in the production, accumulation, and application of knowledge. Universities have increasingly been at the centre of such knowledge production, application and transfer. Yet, there is little research and evidence in this regard pertaining to less developed countries. The paper aims to fill this gap. The study uses the conceptual notion of knowledge transfer to interrogate the engagement level between the university and its region. Using a qualitative approach comprising the use of primary and secondary data, the authors capture some of the factors affecting knowledge transfer. Highlighting both supply-side and demand-side factors, the authors argue in favour of a nuanced and complex negotiation of the knowledge-development interface between universities as knowledge producers and regional stakeholders as knowledge users. Such negotiations should take cognisance of local realities.

土地征用制度的经济学分析及改革思路

从经济学角度出发，运用生产者与消费者剩余，分析了土地征用制度的市场效率；指出现行制度供给不足是导致征地权滥用与征地行为不规范的根源；并指出制度的“路径依赖”性导致制度变迁的阻力较大。鉴于此，提出了改革的两种思路——完善土地征用制度和规范土地流转市场。当前应完善土地征用制度，随着经济发展与制度环境的改善，再过渡到全面改革土地征用制度上。

从后现代知识观谈未来教师的角色转变

后现代主义思潮是20世纪末西方社会流行的一种哲学和社会思潮,其中自利奥塔所提出的后现代知识观后,知识的形式、性质、传递方式和价值都发生了前所未有的变化。这对旨在传递知识的教师提出了新的要求:未来教师应该放下传统的权威角色,成为学生学习知识的合作者、促进者、终身学习的先行者及课堂教学的设计者,以便更好地适应当代教育的发展。     

数学技能教与学的若干思考

有3个因素影响着数学技能的掌握与类化，这就是知识的理解水平，练习的感悟水平和认知策略的迁移水平，而传统的技能学习在这几方面均存在问题．随着课程改革的不断深入，除了重新认识数学技能的内涵外，还须改进数学技能的教学观念与方式，比如，控制训练的量与度，在变式训练的同时引导学生感悟、反思，让学生自我体会数学思想方法等．     

社会资本与教育公平

在现代社会影响教育公平的诸多因素中，社会资本因素是一类重要的社会因素。在当今市场化的社会发展形态中，存在大量与学生受教育过程密切相关的社会资本失衡现象。社会资本的不平等对于学生的受教育机会公平、社会化处境、教育质量公平、乃至职业与社会地位获得均产生了显著影响。中国市场化的社会转型过程中有必要关注社会资本对教育公平的影响。     

朝鲜语母语学习者趋向补语习得情况分析--基于汉语中介语语料库的研究

本以汉语中介语语料库中母语为朝鲜语的学生使用的带趋向补语的句子为样本,考察了这些学生习得趋向补语的情况,分析了影响他们习得趋向补语的因素。章发现,这些学生习得趋向补语出现的错误既受语际负迁移的影响,也受语内负迁移的影响。
