普通高校成人教育与网络教育融合的现状与思考

随着现代信息技术的飞速发展,成人学历教育中的网络教育和传统教育已不再是两个界限分明的世界。将两形式综合起来运用,则会扬长补短、符合时代发展需求、达到最佳效益。因此两种教育形式的融合已经成为业内人士共同的议论话题,并进入国家教育管理部门考察和制定政策的视野。作为该项工作的具体参与者,笔者试图基于混合学习原理的视角,对两种教育形式融合中存在的问题和对应策略进行探索与尝试。     

基于改进Elman神经网络的氧化铝浓度控制建模

铝电解过程是一个非常复杂的非线性、时变和大滞后的工业过程体系,因而采用常规的控制方法很难达到良好的控制效果。针对此问题本文提出了采用改进的Elman神经网络对其进行建模,介绍了改进Elman神经网络结构及其学习算法;分析了影响氧化铝浓度的主要因素,并根据实际情况确定了输入层和中间隐层的维数,从而确定了模型的结构。通过对现场采集的数据进行了仿真,仿真结果表明：与常规Elman相比,神经网络收敛速度和稳定性上都有明显提高,得到了令人满意的结果。     

Investigating effectiveness and user acceptance of semantic social tagging for knowledge sharing

Social tagging systems enable users to assign arbitrary tags to various digital resources. However, they face vague-meaning problems when users retrieve or present resources with the keyword-based tags. In order to solve these problems, this study takes advantage of Semantic Web technology and the topological characteristics of knowledge maps to develop a system that comprises a semantic tagging mechanism and triple-pattern and visual searching mechanisms. A field experiment was conducted to evaluate the effectiveness and user acceptance of these mechanisms in a knowledge sharing context. The results show that the semantic social tagging system is more effective than a keyword-based system. The visualized knowledge map helps users capture an overview of the knowledge domain, reduce cognitive effort for the search, and obtain more enjoyment. Traditional keyword tagging with a keyword search still has the advantage of ease of use and the users had higher intention to use it. This study also proposes directions for future development of semantic social tagging systems.     

社会创新及其与技术创新的协同发展

文章在剖析社会创新的内涵及特征的基础上,分析了社会创新对技术创新的影响机制以及二者协同发展的途径。研究表明,社会创新往往是技术创新的前提、伴随情况或结果,技术创新则为社会创新的实现提供了手段与工具。建设创新型国家的关键在于实现技术创新与社会创新的互动与协同．而社会企业及企业社会创新是推进”社会创新一技术创新”协同发展的重要形式。     

高校研究生科研贡献度实证研究*—以暨南大学人文社科类研究生为例

随着高校扩招,研究生的数量越来越多,他们不仅是受教育的客体,也是科研力量的生力军。研究生综合素质不仅仅指学生成绩的高低,更重要的是其科研能力的培养、协作能力的培养、解决问题能力的培养等方面。科学研究是研究生教育的核心和关键, 而目前国内对于研究研究生参与科研工作的学术研究成果较为缺乏,本研究重点关注的是人文社科类研究生对学校科研方面的贡献及价值体现,通过分析总体贡献度及各类具体指标,进而挖掘影响研究生科研贡献的背后因素,包括政策诱因、评价制度等。

生态工业园区规划的理论综述

作为一种新型的工业组织形式,生态工业园（EIP）得到了人们的广泛关注。本文在对EIP内涵进行界定的基础上从工业生态、生态系统和景观生态三方面论述了其运作的基础理论：提出应依照总体规划、分步实施的原则进行EIP的规划,即在项目背景分析的基础上。对物质流系统进行科学规划,然后分步开展共生网络的合理构建、环境友好的系统设计和生态文化的营造等．最终将EIP建成功能完备、环境友好、景观优美、文化浓郁的工业生态社区。     

Regulatory policy as innovation: Constructing rules of engagement for a technological zone of tissue engineering in the European Union

This paper addresses the question of the part that regulation plays in processes of innovation in sectors of technology. The politico-economic phenomenon of ‘Europe’ is partly constituted by regulatory regime-building, and new technologies are one of the major sites of regime-building. A constructionist social theory perspective shows that study of the conflictual processes of regulatory policymaking affords insights into the formation of the rules of engagement that constitute technology domains. Adopting the concept of emergent ‘technological zone’ in preference to industrial ‘sector’ or technoscientific network, the paper presents, using empirical research, a detailed account of the case of the debate and development of regulatory policy for therapeutic tissue engineering in the European Union's policy institutions and stakeholder networks. It describes how the jurisdiction of an emergent zone has been formed through such negotiations, providing a counter-example to the common view that regulation ‘lags behind’ innovation. The analysis takes account particularly of the part played by the malleability of the definition of the material technology itself in such constructive governance processes, and it also suggests various consequences for the array of producers of the technology, for market structuring and for the innovation pathways taken by tissue engineering technology. Concluding, the paper argues that there is conceptual advance to be made by bringing together constructionist social theory with innovation studies approaches that highlight the part played by non-firm, public institutions in shaping innovation ecologies.
