基于长尾理论的数字图书馆用户保障 总被引:10,自引:0,他引:10
长尾理论关注小众市场和用户的思路为数字图书馆的用户保障提供了新视角,在实现信息服务总体目标、应对信息市场的竞争形式和顺应信息服务的个性化趋势方面具有重要的启示意义。在信息生产、信息船体和信息供求的长尾驱动下,通过识别和细分用户、完善信息资源体系、高效揭示和检索信息、注重用户个性化服务,长尾理论能为数字图书馆用户保证提供现实指导。 相似文献

公共治理视野下公共图书馆的经费问题 总被引:2,自引:0,他引:2
经费短缺是公共图书馆发展的瓶颈。政府拨款是图书馆的主要经费来源。但图书馆是公共物品,公众的事务公众办。争取政府较多的投入要靠公众对图书馆治理的参与。解决公共图书馆经费问题要实现从行政依赖的“图书馆管理模式”向公众参与的“图书馆治理模式”转型。通过图书馆立法、健全图书馆行业组织、公众参与图书馆治理等几方面努力,改善图书馆的法治环境,解决图书馆财政困难,实现公众参与的和谐社会目标。 相似文献

As the number and diversity of distributed Web databases on the Internet exponentially increase, it is difficult for user
to know which databases are appropriate to search. Given database language models that describe the content of each database,
database selection services can provide assistance in locating databases relevant to the information needs of users. In this
paper, we propose a database selection approach based on statistical language modeling. The basic idea behind the approach
is that, for databases that are categorized into a topic hierarchy, individual language models are estimated at different
search stages, and then the databases are ranked by the similarity to the query according to the estimated language model.
Two-stage smoothed language models are presented to circumvent inaccuracy due to word sparseness. Experimental results demonstrate
that such a language modeling approach is competitive with current state-of-the-art database selection approaches. 相似文献

This paper examines how research impact is defined, measured, and generated – with a view to understanding how it can be enhanced within heritage conservation. It examines what is meant by ‘impact’ and how it can be promoted within heritage science through effective inter-disciplinary collaboration. Following a general examination of the current discourse concerning research impact, the study examined: (i) active research networks within heritage science; (ii) research planning and evaluation practices within heritage science; and (iii) the experiences of users (i.e. conservators and other heritage professionals) within research collaborations. Terminologies surrounding the notion of impact and the various phases of the research process were reviewed – from the initial identification of a knowledge gap to the eventual application of new findings in practice. Next, the reach and diversity of research collaborations (as identified through publication co-authorship) were studied to characterise the inter-disciplinary nature of heritage science and its connectedness to users. Findings showed substantial growth in international research collaborations over recent years, predominantly involving academic- and research-oriented institutions – although the engagement of heritage institutions has proportionally decreased. In addition, a worldwide survey of institutional planning and evaluation practices revealed a general reliance on processes driven by the interests of researchers – the systematic consideration of stakeholder opinion and evaluation of research outcomes being less common. Finally, a series of semi-structured interviews with senior heritage professionals explored their experience of collaborative research. The results identified key areas where strategic support is needed to promote user participation and enhance impact. These include training for research readiness, engagement, and impact for both researchers and users; better methods for needs and outcome assessment; affordable open access options and greater diversity of knowledge exchange opportunities. Finally, the need for ethical guidelines for responsible research, and greater emphasis on non-academic impact within research rating systems are discussed. 相似文献

展览开发是博物馆展览的基础问题,随着公众参与逐渐被提上研究议程,也促使我们去思考展览开发过程中如何引入公众参与。美国的科技博物馆展览开发已经建立了较为完善的公众参与体系:明确的参与者角色、系统的参与理念和阶段式的参与行为,已经获得了普遍的应用。借鉴美国博物馆的经验,我国博物馆展览的开发,应在构建展览评估体系的基础上,进一步了解和认识公众,拓展公众参与的方式,并不断寻求公众的声音。 相似文献

This study examines the political participation intentions of North Korean women refugees. Previous literature tends to highlight the sufferings and difficulties that female refugees experience as they leave their homelands and settle in a new country. Few studies have been directed toward the political dimension of refugee life. The empirical results show that North Korean women defectors hold generally participatory attitudes toward politics and mostly liberal opinions on policy issues. Furthermore, among the socio-demographic variables, age and marital status are generally influential in the intention of political participation among the North Korean women defectors. Among the political attitudinal variables, attitude toward environmental policy consistently affects political participation intention. With respect to defector-specific variables, satisfaction with life in South Korea is influential, whereas cultural adaptation is not. 相似文献

四谛是佛教中南北传的佛教、汉藏传的佛教所共遵的基本教义,彼此共同认为这是世问、出世间的唯一解脱之道。后世诸佛弟子虽认为四谛为声闻、缘觉之法,意思就是贬四圣谛为小未法,其实大未佛教四弘誓愿的实践是依四圣谛而发起。从四圣谛到四弘誓愿,体现了佛教由小来的融和和展开。 相似文献
