网络信息生态环境评价与优化研究

网络信息生态环境的优化可以促进网络信息生态系统和谐发展和进化,且必须以评价为基础。网络信息生态环境的评价应从政治环境、技术环境、人文环境、经济环境四大方面进行。文章构建了网络信息生态环境的评价指标体系,并提出了优化策略。     

非相关文献知识发现的关键技术研究

本文在对非相关文献知识发现中的关键技术进行界定的基础上,对11个国外主要的非相关文献知识发现研究中所涉及的关键技术,即初始文本集的构建、信息抽取及中间关联词的确定与排序等进行了比较研究,认为B集合质量低是非相关文献知识发现目前存在的主要问题.针对该问题,作者提出以提高B集合的质量为主要目标,从B集合形成的前过程,即初始文本集的质量以及B集合本身的质量,即B词的排序两个方面的改进策略.前者包括初始文本集的合理结构及综合过滤机制,后者包括双向词频法、基于MeSH加权和基于文献内聚力加权.并对部分改进策略进行了试验.     

Conceptualizing an East Asian popular culture

Since the 1980s, popular cultural products have criss‐crossed the national borders of East Asian countries, enabling a discursive construction of an ‘East Asian Popular Culture’ as an object of analysis. The present essay is a preliminary attempt to provide some conceptual and analytic shape to this object, delineated by its three constitutive elements of production, distribution and consumption. Each East Asian location participates in different and unequal levels in each of these component processes. Production can either be located entirely in a single geographic location or, alternatively, each of the necessary constituent sub‐processes can be executed from different locations; preference for either arrangement tends to reflect the relative dominance of the production location in exporting its finished products. Consumption and thus consumers are geographically located within cultural spaces in which they are embedded. Meanings and viewing pleasures are generated within the local cultures of specific audience. Conceptually, among the several possible consumption positions, the one in which an audience watches an imported programme is most intriguing. In this viewing position, differences between the cultures of the location of consumption and that of the production location become most apparent. The audience member has to bring his or her own cultural context to bear on the content of the imported product and read it accordingly. In this sense, the cultural product may be said to have crossed a ‘cultural’ boundary, beyond the simple fact of its having been exported/imported into a different location as an economic activity. Such an audience position requires the consumer to transcend his or her grounded nationality to forge abstract identification with the foreign characters on screen, a foreignness that is, in turn, potentially reabsorbed into an idea of (East) ‘Asia’; a potential ‘East Asian identity’, emerging from consumption of popular cultural products, is thus imaginable.     

北京普通幼儿家长全纳教育观念的调查

幼儿家长是学前全纳教育中的"利害关系人",其态度直接影响子女对特殊同伴的态度并决定了其子女所在幼儿园是否愿意招收特殊儿童.要在我国实施学前全纳教育应首先要了解普通幼儿家长对全纳教育的看法.本研究通过问卷调查发现:北京地区普通幼儿家长对全纳教育对特殊及普通儿童的积极作用认识不足,并认为普通幼儿园教师缺乏全纳教育的经验和资质,对其全纳教育的能力缺乏信心.此外,他们普遍对自己子女所在班级招收特殊儿童的做法持保守态度.     

基于RS技术的洪泽湖周边地区遥感影像信息提取

洪泽湖,中国第四大淡水湖,在江苏省西部淮河下游。本次研究的周边地区包括泗洪县、洪泽县、泗阳县、盱眙县,还有淮安市区中的一部分。本文运用遥感和地理信息系统技术,先用研究区的行政区划图对2010年遥感影像进行几何校正,再进行裁减获得洪泽湖周边范围遥感影像信息,为后期洪泽湖周边地区土地利用及生态效应影响等研究提供基础遥感信息源。     

论媒介素养教育与思想政治教育的有效结合

媒介素养教育与思想政治教育的对象的相同性、目的的一致性、内容的关联性、方法的相通性、途径的相似性为两者的结合提供了极大的可能性,而且素质教育的要求、思想政治教育自身发展的要求、媒介素养教育在中国本土化的发展要求使两者的结合非常有必要.将媒介素养教育纳入思想政治教育体系,用思想政治教育的内容来引导媒介素养教育,是对两者有效结合路径的思考,其教育过程大致分为理论学习、思考辨析和实践操作三个阶段.
