基于印刷与电子索引工具的文献双检策略——以“高师学生心理素质研究”项目为例   总被引：2，自引：0，他引：2  

徐建平  孟莉 《中国图书馆学报》2004,30(2)

双检策略,是指同时采用印刷本和电子数据库两种索引工具来完成同一课题文献检索的方法。其做法是根据课题内容要求,选择合适的检索工具,分别采用其纸印本和光盘或网络版,进行文献检索,并对其结果进行分析、选择。双检策略不仅能保证文献查询全面、准确,而且能保证质量,利于科研。参考文献6。  相似文献

Inverted Index Compression Using Word-Aligned Binary Codes   总被引：3，自引：1，他引：3  

Vo Ngoc Anh  Alistair Moffat 《Information Retrieval》2005,8(1):151-166

We examine index representation techniques for document-based inverted files, and present a mechanism for compressing them using word-aligned binary codes. The new approach allows extremely fast decoding of inverted lists during query processing, while providing compression rates better than other high-throughput representations. Results are given for several large text collections in support of these claims, both for compression effectiveness and query efficiency.  相似文献   

Technological capital: an alternative to the digital divide     

Andrew Carlson  Alyssa M. Isaacs 《Journal of Applied Communication Research》2018,46(2):243-265

This paper identifies individuals’ accumulated history with Information and Communication Technologies (ICTs) as a replacement for the contested and outdated term ‘digital divide.’ We propose that an individual’s ability to benefit from their technological history consists of four factors: awareness, knowledge, access, and technological capacity of the user’s social collective. Together, these factors make up the individual’s level or amount of Technological Capital. The development of this construct was based on empirical research conducted in Soweto, South Africa, and through an analysis of the literature on assessing individuals’ accumulated histories. The concept of technological capital has the potential for application in fields in which ICTs are used for communication, capacity building, and identifying barriers to adoption of new technologies. The use of the concept may have implications for policy decisions, resource allocation, and future research into differences among individuals’ and communities’ ability to benefit from the introduction of new technologies.  相似文献

“Oh,I’m Here!”: Social Media’s Impact on the Cross-cultural Adaptation of Students Studying Abroad     

Todd L. Sandel 《Journal of Intercultural Communication Research》2014,43(1):1-29

This study investigates the perceptions and interpretations of social media and online communication by students engaged in study abroad programs. In-depth interviews were conducted and analyzed with 23 American and international students who completed or were engaged in a study abroad program. Results suggest that online communication enhanced the students’ experience, providing help with sociocultural skills, informational needs, relational bonds, and psychological well-being. Different platforms were preferred when communicating with friends versus family and intimates. Online communication between co-nationals from the student’s home country buffered both the sojourning student’s acculturative stress, and the stress and concern of distant family members.  相似文献   

基于对应分析模型原理的户外运动安全风险研究     

欧雅怡  刘〓亚  马逢伯 《广州体育学院学报》2017,37(2):43-48

通过对我国2001年至2014年期间,258个户外运动安全事故案例的统计和分析,结合国内外相关研究,建立户外运动安全风险分析框架,将户外运动安全风险划分为4个维度,18个因素指标.根据对应分析模型原理,深入研究户外运动中季节、月份与时段风险的对应性关系,R(3.2.0)软件运行结果显示:户外运动中,凌晨和晚上的风险指数最高;春季、秋季的上午和下午时段,可能存在的伤亡风险几率较高;5月、9月、10月的上午和晚上,3月、6月、11月、12月的下午,1月和4月的凌晨时段,可能存在的伤亡风险几率更高.使用Minitab软件,根据累积贡献率80％以上为主要因素的帕累托原则得到8个主要风险因素和7个次要风险因素.  相似文献   

On Adaptation and Alienation in Translation     

周小惠 《海外英语》2014,(22):173-174

From cultural point of view,there are two methods in translation:adaptation which is TL culture-oriented and alienation which is SL culture-oriented.What this article tries to prove is that each of them has its own strong and weak points,which leads to the conclusion that both methods are justified in their existence.And last,some points for attention are suggested for translation,which include the relationship between SL and TL,the type of texts and the translator’s purpose.  相似文献   

中华龙舟文化演变的生态适应论绎     

王洪珅 《北京体育大学学报》2017,40(6):134-139

摘要：主要采用文献资料法和历史研究法，以跨学科的视野阐释和分析中华龙舟文化在不同历史时期的变化，从生态适应的角度，纵向梳理了中华龙舟文化的发展历程，认为中华龙舟文化的起源、演变及传承等整个发展过程均是生态适应的结果。主要从自然生态、社会生态和文化生态3个维度，分析讨论了中华龙舟文化演变过程中的生态适应问题。研究认为：自然生态促进了中华龙舟文化区域性的演成，并赋予其地域性特征；社会生态促使中华龙舟文化服务于政治需要、社会教化和社会整合；而文化生态促进了中华龙舟文化与他文化的横向交流和融合。同时还认为，面对自然生态、社会生态和文化生态的不断变化，当前及今后的中华龙舟文化都会通过不断的自我调适来适应所处生态的变化。一定程度上有助于加深对中华龙舟文化发展问题的理解和认识，进一步拓展民族传统体育文化研究的视野。  相似文献
