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

On February 24, 2022, Russia attacked Ukraine, an independent country. Although the topic of academic library assistance directed to Ukrainian refugees has appeared in the media, the review of literature demonstrated that these activities have not been documented in the scientific literature so far.The aim of the study was to find out what actions addressed to the Ukrainian refugees.Polish academic libraries took to help build social resilience in case of war.The study used quantitative and qualitative methods: the survey method and the heuristic method. The survey was sent to all directors of state academic libraries in Poland.The collected data were divided into the domains: institutional, social, physical and economical. These domains were then used to design a library model of building community resilience in case of war, and to describe the links between these domains.The multi-level spectrum of activities undertaken by the academic libraries in Poland to improve the situation of Ukrainians and described in this paper lead to the recognition that libraries: are important institutions of social trust, and in order to maintain this status, they have to respond to the needs of local communities on an ongoing basis.  相似文献

Delivering public services to citizens via the Internet is the basic goal of E-government. Although websites are becoming essential elements of public e-services in local public administration in China, little is known about their efficiency and effectiveness. The objective of this paper is to evaluate the actual status of Web-enabled public services to citizens in municipal e-government implementation in the Yangtze River Delta. Eight categories of public services to citizens delivered through the Internet have been identified in the websites of the 14 local municipal governments. These public services include birth, marriage, domicile register, education, social security, public utility, health and traffic. Using the methodology of service maturity, this study evaluates the quality and usage of public e-services to citizens in the Yangtze River Delta. The results of this study show that almost all city governments are shifting from the traditional bureaucratic paradigm to the e-government public service paradigm, albeit with significant differences in public e-services level in these cities. At present, e-government public services to citizens in almost all the cities studied are mostly limited to on-line presentations of government information with a low degree of development of interaction and on-line transaction. The municipal governments and policymakers in the near future will have to strengthen the interactivity of their websites with citizens and improve the on-line transaction level in order to deliver citizen-centric public e-services.  相似文献

This article reports on researching “Middle East: Information Literacy awareness and indigenous Arabic World Wide Web content challenges”. The research reported upon was conducted in preparation for a training presentation which was delivered as a part of the UNESCO “Training the Trainers” (TTT) in Information Literacy workshop project that was held November 6–8, 2008 at the Bibliotheca Alexandrina in Alexandria, Egypt. Although the concept of Information Literacy is relatively new worldwide, by now it is fairly well understood, practiced and pedagogically supported in the developed world. But, it is still quite a mystery for developing countries, especially in the Middle East and North Africa regions. Therefore, the presentation the authors were invited to deliver at the workshop aimed at creating a much needed broader awareness concerning the concept of Information Literacy, including the somewhat differing definitions which are used in various world regions and cultures, and the concept’s relevance to the advancement of knowledge, research, and the general level of education in the Arabic speaking world. Special attention was paid to these problems in the context of challenges faced by higher education institutions in the Middle East and North Africa regions.

The authors discovered that the problem of the scarcity of indigenous Arabic content materials on the World Wide Web is inextricably related to the challenges of increasing the awareness of Middle East and North Africa audiences to the relevance of Information Literacy. The authors endeavor to explain in detail what this inter-relationship is, and why and how the increase of Arabic materials on the Web could then lead to an increase in the awareness of Information Literacy in those Arabic speaking regions.

The workshop presentation aimed at explaining and promoting Information Literacy skills, not only to students and researchers, but also to future Information Literacy trainers (the participants at the UNESCO workshop). The language barrier, the Digital Divide, and the lack of adequate Arabic digital content/resources relating to Information Literacy, were all reviewed with the workshop participants, illustrated by real world case examples, and discussed, in an effort to simultaneously try to work toward a consensus approach to teaching and learning the IL concept, and at the same time create a heightened Information Literacy awareness. Rather than simply amplify in detail the technical contents of the workshop presentations the authors made in this article, and with the encouragement of the Review’s editor and guest editor, the authors decided to “tell their story” in anecdotal fashion, sharing with the workshop participants tales of the many challenges they faced in just preparing materials for their presentations – and covering both the presentation format and the presentation content aspects, including explaining why they selected a specific teaching and learning approach, and how they dealt with various delivery and implementation challenges. By so doing, readers faced with similar teaching challenges might be better prepared to respond to the many challenges, both in the context of the preparations they will be required to make as well as in the context of their actual content delivery at their workshops.  相似文献

Objective:To compare the accuracy, time to answer, user confidence, and user satisfaction between UpToDate and DynaMed (formerly DynaMed Plus), which are two popular point-of-care information tools.Methods:A crossover study was conducted with medical residents in obstetrics and gynecology and family medicine at the University of Toronto in order to compare the speed and accuracy with which they retrieved answers to clinical questions using UpToDate and DynaMed. Experiments took place between February 2017 and December 2019. Following a short tutorial on how to use each tool and completion of a background survey, participants attempted to find answers to two clinical questions in each tool. Time to answer each question, the chosen answer, confidence score, and satisfaction score were recorded for each clinical question.Results:A total of 57 residents took part in the experiment, including 32 from family medicine and 25 from obstetrics and gynecology. Accuracy in clinical answers was equal between UpToDate (average 1.35 out of 2) and DynaMed (average 1.36 out of 2). However, time to answer was 2.5 minutes faster in UpToDate compared to DynaMed. Participants were also more confident and satisfied with their answers in UpToDate compared to DynaMed.Conclusions:Despite a preference for UpToDate and a higher confidence in responses, the accuracy of clinical answers in UpToDate was equal to those in DynaMed. Previous exposure to UpToDate likely played a major role in participants'' preferences. More research in this area is recommended.  相似文献
