学术文献引文上下文自动识别研究   总被引：2，自引：2，他引：0  

雷声伟  陈海华  黄永  陆伟 《图书情报工作》2016,60(17):78-87

[目的/意义] 引文内容分析能够帮助揭示文献引用关系的深层语义内涵,而引文上下文识别作为引文内容分析的基础显得尤为重要。[方法/过程] 梳理已有引文上下文研究的现状,总结当前引文上下文识别的不足,在此基础上归纳引文上下文识别的5类特征,并采用文本分类和序列标注两种方法开展引文上下文自动识别实验。[结果/结论] 实验结果表明,本文提出的特征能够很好地提升引文上下文识别效果,且基于文本分类的SVM分类效果要优于基于序列标注的CRF。  相似文献

Asian Martial Arts: The Anarchic Legacy of the War Machine     

Barry Allen 《国际体育史杂志》2016,33(9):882-892

Abstract

The renaissance of Asian martial arts is a conspicuous example of cultural hybridity in a global setting. Globalization brings these arts under the dual sway of cinema and sport to a degree unprecedented in their history. This pull, which I describe in terms from Deleuze and Guattari as deterritorialization, creates new challenges for Asian martial arts practice. To explore these challenges and their stakes, I demonstrate the relevance of the concept of the war machine from Deleuze and Guattari, and discuss their distinction between weapons and tools as it bears on Asian martial arts history and practice.  相似文献   

我国图书出版的经济效应--基于面板向量自回归的脉冲分析     

朱江丽  李子联 《出版科学》2016,24(6):75-79

运用面板向量自回归模型分析后发现：东部地区图书出版对经济增长带来了“先增强后减弱”的正向冲击效应,中部地区的冲击效应既不明显也不稳定,西部地区则呈现负向冲击效应。同时,东部地区出版产业的延伸和知识的外溢使得全国的图书出版带来经济的有效增长。但是,这一效应主要是通过“产业渠道”而非“传播渠道”传导的,这就使得图书出版数量上的扩张只是带动了出版产业的发展,而未能带来出版知识快速且有效的转化。  相似文献   

21世纪中国崛起之依托:雄鸡发展战略模式   总被引：2，自引：0，他引：2  

张义明  李影  王春晓 《新乡师范高等专科学校学报》2004,18(3):59-62

"中国雄鸡发展战略模式"是从象形的角度假设命名的,即中国像一只昂首挺立于东方的雄鸡,并伸展着两个巨大的翅膀:"北翼"是上海合作组织,"南翼"是中国———东盟自由贸易区。实际上它是对中国在21世纪以更积极、更开放的姿态走向世界,迎接挑战,把握机遇,而投身于区域经济集团化浪潮中的发展战略总和的抽象概括。这种发展战略模式是以中国的崛起为前提的,也是以中国的崛起和发展为动力的,同时也是有利于中国的崛起和发展的"双赢"模式。随着这只雄鸡不断地茁壮成长,中国才能从容不迫地发挥一个世界大国的作用。  相似文献   

Special educational needs in mainstream secondary school physical education: learning support assistants have their say     

Anthony John Maher 《Sport, Education and Society》2016,21(2):262-278

Learning support assistants (LSAs) gained more political and academic attention in Britain after Estelle Morris announced that schools of the future would include more trained staff to support learning to higher standards. LSAs, thus, should form an integral part of the culture of all school departments in Britain, including physical education (PE). The paper uses Antonio Gramsci's concept of hegemony to explore the processes and practices that shape the views and experiences of LSAs and ultimately the extent to which they facilitate an inclusive culture in PE. A web survey gathered the views and experiences of LSAs vis-à-vis the inclusion of pupils with special educational needs (SEN) in mainstream secondary school PE in North-West England. A modified version of the tailored design method participant contact strategy resulted in 343 LSAs starting the web survey, with 154 (45%) following it through to completion. All quantitative data were analysed using Microsoft Excel whilst qualitative data were subjected to thematic analysis. This entailed the identification of recurring themes and patterns present in the data. The findings highlight the hegemonic status of English, maths and science when it comes to the allocation of SEN resources, which most LSAs support and often reinforce. PE is particularly disadvantaged in this hierarchy of subject priority. The majority of LSAs have not received PE-specific training, which brings into question their ability to facilitate inclusion in PE. Moreover, many schools do not appear to value the involvement of LSAs in the planning of differentiated lessons, which could have a negative impact on the PE experiences of some pupils with SEN given that LSAs are perhaps most aware of the specific learning needs of the pupils they support.  相似文献   

日本环境教育探析     

李培超 《湖南师范大学教育科学学报》2004,3(3):69-73

日本在发展经济的过程中非常重视环境教育，其基本着眼点是：通过对传统文化的挖掘和诠释，搭建起环境教育的价值支持系统；通过政府、企业、社区、NGO组织(Non-governmental organization，非政府组织)的共同努力、协同配合，构造出完整的环境教育体系；通过公害教育使社会民众始终保持对环境问题的敏感性。这些做法可以为我国的环境教育提供重要的启示和参照。  相似文献
