基于频度演化的领域知识关联关系涌现     

滕广青 《中国图书馆学报》2018,44(3):79-95

领域知识的生长演化问题一直是图书情报学界重点关注的主题。以网络科学思维探索知识生长过程中的关联关系涌现问题,能够对知识关联的生长模式与机制进行揭示。本研究提取知识关联关系累计44万余对,关联频度87万余次,共划分为11个时间窗口。在对时间序列领域知识网络结构属性初步判识的基础上,对关联频度分布进行时间序列分析。并从领域知识生长过程中的关联频度数量、关联频度占比、邻近窗口状态等方面,对知识关联关系及其频度进行跟踪与分析。研究结果表明,知识关联关系生长过程中,关联关系频度的分布符合幂律分布,且在领域知识发展的成熟期表现得更好。知识关联关系的生长过程具有频度层面的“富者更富”的属性,且主要遵循“择优强化”机制。尽管研究所使用的基于社会化标注系统的知识网络尚不足以囊括所有类型的知识网络,但是基于频度演化的知识关联关系涌现模式与机制,有助于促进知识网络、知识生长等领域的研究工作,对于社交网络、传播网络、交通网络等研究不无裨益。图5。表4。参考文献30。  相似文献   

Pathways of Immigrant Political Socialization: Examining the Role of News Media,Social Connections,and Community Interaction     

Wenlin Liu  John Gastil 《Journal of Intercultural Communication Research》2014,43(3):238-263

Going beyond the traditional socioeconomic status model of political participation, this study examines pathways that lead to the sociopolitical incorporation of immigrants in the USA, with a focus on the role of communication socialization agents. Using a Current Population Survey sample of 7,626 first-generation immigrants in the USA, results show that communication socialization agents significantly contribute to immigrants’ political socialization, and an important mediating path translates political learning into greater political engagement. Results also identify ethnic differences in how socialization variables affect immigrants’ socialization.  相似文献

Increasing engagement of students with learning disabilities in mathematical problem‐solving and discussion     

Rachel Lambert  Trisha Sugita 《Support for Learning》2016,31(4):347-366

Engagement in problem‐solving and mathematical discussion is critical for learning mathematics. This research review describes a gap in the literature surrounding engagement of students with Learning Disabilities in standards‐based mathematical classrooms. Taking a sociocultural view of engagement as participation in mathematical practices, this review found that students with LD were supported towards equal engagement in standards‐based mathematics through multi‐modal curriculum, consistent routines for problem‐solving, and teachers trained in Mathematical Knowledge for Teaching. Using this small set of studies (7), we identify the need to deepen the engagement of students with LD in mathematical problem‐solving and discussion. This review concludes with implications for teaching and learning.  相似文献   

The effects of school-based physical activity interventions on students' health-related fitness knowledge: A systematic review     

《Educational Research Review》2015

This systematic review includes 34 studies examining the effects of school-based physical activity interventions on students' health-related fitness knowledge. The study design, methodological quality, and effectiveness of interventions on students' health-related fitness knowledge were analysed. The majority of the studies (79.4%) revealed significant positive intervention effects on students' health-related fitness knowledge. Studies examining adolescents were more frequently in a position to influence students' health-related fitness knowledge (87.5%) than studies examining children (75%), and studies with low methodological quality (88.8%) had more frequent positive effects than studies with moderate quality (75%). The effects on students' health-related fitness knowledge were independent of moderator variables such as the intervention content, duration and frequency. Only few studies were able to simultaneously positively influence students' health-related fitness knowledge and students' physical activity and/or fitness levels. These programmes can positively influence students' health-related fitness knowledge, but it remains unclear what the practical significance of these changes is. Further research is needed to clarify the influence of students' health-related fitness knowledge on reflection, understanding, physical activity behaviour, and overall physical literacy levels.  相似文献   

社会网络视角下的企业知识网络研究     

李家清  张慧 《未来与发展》2010,31(1):84-88

知识经济时代，知识成为企业核心资源；知识的更新速度不断加快，而企业所拥有的知识存量有限，为保持竞争优势，知识网络已成为组织实现知识管理的有效实践工具和实践知识管理的主要平台。文章从社会网络视角入手，探讨了企业知识网络概念及内涵，分析了社会网络三大核心理论——强弱联结、社会资本、结构洞，论述了该理论对企业知识网络的影响，提出了构建企业知识网络交流平台的方法。  相似文献   

浅谈费希特知识学     

荆文凤 《鸡西大学学报》2005,5(2):24-25

费希特知识学的基础和核心是“自我”，费希特知识学就其特点来说是主观唯心主义的；费希特对自我积极实践性的颂扬反映了时代的呼声，肯定了实践的作用，尽管其强调实践是认识领域内的实践，还是为哲学发展起了推动作用。  相似文献   

数字人文研究演化路径与热点领域分析   总被引：3，自引：2，他引：1  

柯平  宫平 《中国图书馆学报》2016,42(6):13-30

数字人文是计算机学科和人文学科交叉研究的一个新领域,由计算人文和人文计算领域发展而来。本文以Web of Science核心数据集为来源,运用文献计量方法,结合可视化分析工具,对数字人文研究文献进行统计分析和内容挖掘,分析数字人文研究的前沿和热点领域,明确演化路径和发展趋势。①数字人文研究的热点领域有:数字人文的基本理论,技术驱动下的人文学术实践转向,新合作模式引发的人文学术文化变革,以及面向数字人文研究的基础设施建设;②数字人文研究的内涵更具兼容性,应强调计算转向,考虑重构人文知识的脉络与内容,构建当代知识系统及认知方式;③图书馆学的理论、方法及实践与数字人文研究形成协同发展趋势;④从技术应用和数据基础的角度看,图书馆学是数字人文产生的基础学科,也将是数字人文成果的主要应用学科之一。我国图书馆界应以融合的视角审视数字人文与图书馆发展的关系,进行数字人文的理论研究与实践探索。图10。表1。参考文献54。  相似文献   

知识融合:概念辨析与界说     

刘晓娟  李广建  化柏林 《图书情报工作》2016,60(13):13

[目的/意义] 知识融合是一个随技术环境和社会环境不断发展变化的概念,并可应用于多个学科领域,然而目前学术领域对知识融合的概念界定还缺少一致的理解,对其进行辨析有利于推动后续研究。[方法/过程] 通过充分调研和分析,在理论和实践层面汲取以往研究中的观点和成果,一方面选取不同时期和不同领域的知识融合概念的典型表述,并分别提取“处理对象”“融合过程”以及“融合结果”3个关键要素;另一方面通过知识融合系统体系架构的剖析来进一步明确知识融合的研究范畴与边界。[结果/结论] 综合概括得到一个相对完整的知识融合概念定义,并从流程角度对知识融合概念进行分解。  相似文献   

理解:开放、融合与扩充--试析加达默尔诠释学中的理解问题     

刘娜 《河北软件职业技术学院学报》2002,4(4):8-10

加达默尔的诠释学从一个全新的角度论述了理解问题,使哲学诠释学成为一个独立的哲学流派,在现代西方哲学史上产生了巨大的影响。他认为理解是此在本身的存在方式;理解具有历史性;理解按其本性乃是一种效果历史事件,而视域融合又是对效果历史的展示和具体说明。因此,理解效果历史原则是把握加达默尔理解问题的关键。  相似文献
