图书馆精准服务是"互联网+"时代的图书馆发展的必然趋势,要实现"精准"必须关注的基础就是用户。文章在对用户画像理念及国内外研究梳理的基础上,从现有大数据利用状况、主观上精准服务转型的需要和客观上该技术执行可行性三方面分析用户画像技术实现高校图书馆精准服务的可行性。最后在搭建图书馆精准服务架构系统的基础上,提出围绕用户画像实现高校图书馆精准服务的技术过程。  相似文献

文章以出版人张元济的图书馆事业为中心,通过对张元济参与图书馆事业的历程以及其图书馆理念与实践的考察,窥探民国出版界与图书馆界的互动及影响,最后指出,两个看似"跨界"的界别同属特殊的"文化事业"行业,需要紧密合作才能实现共赢,而至今缺乏的就是缺少张元济式的人,一个真正以"文化精神"办"文化事业"的知识分子群体。  相似文献

The purpose of this ecological study was to examine the impact of a library credit course on graduation rates and GPA using pre-existing records. Over 20?years of aggregate institutional data were analyzed to evaluate the course's impact on first-time-full-time, white, and black students. Results were mixed: students who took the course were less likely to graduate than their peers who did not take the course but enjoyed slightly higher GPAs at graduation. It was discovered that students taking the course are not representative of the overall student body and struggle academically. Implications for revisions to the library credit course are discussed.  相似文献

ABSTRACT

The information and knowledge society has resulted in the exponential growth of information and communication technologies (ICTs), thus creating a gap between those who use ICTs and those who do not; hence the emergence of the term “digital divide” in the 1990s. One of the milestones of South Africa’s National Development Plan, a policy that charts the country’s development up until 2030, is to ensure that high-speed broadband internet is universally available at competitive prices. Notwithstanding the importance of ICTs in public libraries, the provision of such is still taking place on a limited scale in South Africa. This article investigates the use of ICTs in public libraries in South Africa as a tool in bridging the digital divide. It also examines the inequalities in access and use and suggests ways in which ICTs may be used to reduce the digital divide. A qualitative research methodology was adopted. In order for public libraries to function as an important tool in bridging the digital divide, there is a need to standardize the provision of public library services with regard to the digital divide.  相似文献

ABSTRACT

The Harwood Institute arrived in Youngstown, Ohio, in 1999; and today, over 18 years later, its teachings have made a profound effect upon the city. The Youngstown Public Library, through the leadership of Carlton Sears and Heidi Daniel, has wholeheartedly embraced the methods and ideology of the Harwood Institute, helping to reinvigorate and power a city working its way back to prosperity.  相似文献

This research examines privacy law and Human Flesh Search (HFS) on the Chinese Internet. HFS is spontaneous, widely participated search and publication of targeted individuals’ personal information on the Internet. This research sees HFS as an important form of non-institutional information gathering and publication, and argues that the regulation of HFS is not only about privacy but also line-drawing for information collection and dissemination in the digital setting. Therefore, legal instruments and court cases in relation to HFS and online privacy must be assessed as important components of the Chinese state’s Internet regulatory scheme. This research finds that the paired concepts of ‘flexibility and populism,’ key features of legal reform and development in contemporary China, are highly relevant to analyze the growth of digital privacy laws in China. The political-legal authorities’ experimentation and innovation in the development of the law shed important light on how China’s Internet governance adapts to changing circumstances and strives to keep pace with profound social transformations in new technological environments.  相似文献

Reports about political scandals have increased lately. Yet the general impact of news visuals and the specific role of lightness and darkness cues in images of scandalized politicians remain unclear. With the help of an experiment, the present pilot study examined the influence of candidate images and the effects of particular image backgrounds (light versus dark). While the foreground of the image depicting a politician involved in a scandal remained unchanged, the background was systematically altered. The results revealed that a light background had a positive effect on recipients’ attitudes toward the politician. In contrast, participants exposed to a dark image background demanded a more severe punishment for the politician.  相似文献
