舆论监督是公众利用报刊、广播、电视等新闻媒介依法表达和传导具有普遍性的意见和看法,从而对社会权力(包括权力组织和个人)、公共政策以及社会行为进行评价和监督,其重点对象是权力组织和决策人物。应该说,正确的舆论监督对于我们揭露问题、批评缺点、纠正失误、改进工作、防治腐败和抑制邪恶发挥了重要的作用,产生了积极的效果。而媒体自身在开展新闻舆论监督的过程中也密切了同群众的关系,扩大了在群众中的声誉和影响,提高了自己的公信力。  相似文献

面对海量的科技文献资源,如何评估文献、作者和研究机构的学术质量和可信度引起了广泛关注。在众多可信度评价标准中,权威度是优先和关键的评价指标。因此,对科技文献、作者和机构等学术实体的科技实力和权威度进行研究与量化评估具有很大的现实意义。本文利用文献、作者、机构等三类实体间的引用、合著、合作等关系建立异构网络模型,在此基础上提出了混合随机游走算法 Co-AcademicRank 定量计算文献、作者、机构的权威度,并基于 MapReduce 实现了分布式的 Co-AcademicRank 算法。最后通过对情报学和图书馆学数据集测试与分析,对比分析了 PageRank 和 Co-ranking 算法,验证了本模型的有效性、准确性和优越性。同时,实验比较了算法在单机环境下和 Hadoop 平台下的运行时间,证明了分布式算法的高效性和稳定性。  相似文献

Science museums play a role in creating visitor experiences that relate to contemporary issues in science, and in linking audiences to the scientific enterprise and the community of scientists. In the Portal to the Public approach, science researchers are trained by museum educators with experience in inquiry‐based learning, and are then given opportunities to translate their current research for museum audiences. Portal to the Public offers one solution to museums seeking to sustain a commitment to delivering experiences that reflect the dynamic pace of research, and the need to connect local communities to scientific research occurring in their midst.  相似文献

School librarianship has advanced in the digital era to encompass interactivity, connectivity, and access to a wide variety of information in different formats, through the capabilities of information and communication technologies. School libraries exist to support learning in schools and the importance of the digital age in student's learning cannot be overstated. Today's students are born in the age of technology; therefore a school library that does not encompass the use of electronic media will not meet the needs of the digital generation. The purpose of this article is to find out the status of technology diffusion and use in Botswana school libraries and to advance reasons for the lack of information and communication technology uptake in school libraries. A document analysis of literature was done to determine the factors that hinder the growth of school librarianship in Botswana during the digital era, using the stakeholder theory as a lens for the investigation. Findings reveal a weakness in the social, political, and economic areas of leadership in national information policies which seem to be a remnant from the beginning of the digital age in Botswana and indeed in most African countries. Some of the recommendations point to using the stakeholder theory to tackle the hurdles in school librarianship leadership and policy in the information age.  相似文献

We examine open access to the Spanish scientific literature via investigation of a sample of peer‐reviewed articles in seven subject categories. Of the 28,259 papers published in 2000, 26.89% were freely accessible, with the share varying among disciplines. Articles in the social and behavioral sciences were the most widely available for free. This disciplinary divide applies also to the strategies used to offer open access to documents. In clinical medicine, life sciences, arts and humanities and social sciences open access was mainly based on the publishers' side, while subject‐based repositories were dominant in physical, chemical and earth sciences and deposit on homepages was the preferred strategy in engineering, computing and technology. Institutional and general repositories seem to play a minor role in providing free access to the Spanish peer‐reviewed literature. Papers published in commercial journals are less accessible than those that appear in non‐commercial journals, and we found overlaps in almost 20% of papers deposited. The fastest way to gain open access is to deposit in subject‐based repositories and the longest delays are related to deposits in homepages and especially to institutional repositories. Open access to Spanish peer‐reviewed articles is dominated by the passive mechanism of the “gold route” and the editorial strategy with self‐archiving practices in the minority and directed mainly towards subject‐based repositories and homepage posting of the papers. The results of this study could serve as a reference point for further study on the evolution of open access in Spain.  相似文献

Celebrities in recent years have taken on a more active role in communicating global humanitarian crises to the American public. This role at times shifts between journalist, advocate, philanthropist, and personal publicist. This article evaluates how three of the most well-known celebrities in this genre in the United States—Angelina Jolie, George Clooney, and Bono—differ in their method of speaking about these issues, focusing on how their public discourse adds to, or detracts from, citizens' abilities to understand, discuss, and respond to the issues presented in the public sphere. Through critical discourse analysis, similarities and differences are teased out and placed within the context of previous research on celebrity diplomacy and humanitarian crises, in order to evaluate the usefulness of such performances for the U.S. public as democratic citizens and for the victims of foreign suffering the celebrities purport to represent.  相似文献

Interest in subject specialists in academic libraries has recently been increasing. After being a trend in the West in the 1960s, interest declined in this method of service provision in academic libraries until its recent return to prominence in the last decade. The purpose of this article is to introduce the current movement of Korean librarianship toward subject specialization in academic libraries, and the efforts that are being undertaken to support that movement. The findings are taken from a large project report funded by The National Library of Korea during 2008. When the project was underway it was very difficult to find articles about trends in non-English speaking countries. With this in mind, we authors decided to publish and share our experiences. This article is expected to be a helpful source for similar research or projects in other countries, and to provide an opportunity to share experiences and communicate.  相似文献
