Librarians in Sweden are facing huge challenges in meeting the demands of their organisations and users. This article looks at four key areas: coping with open science/open access initiatives; increasing demands from researchers for support doing systematic reviews; understanding user experiences in Swedish health science libraries; and the consequences of expanding roles for recruitment and continuing professional development. With regard to changing roles, there is an increasing shift from the generalist towards the expert role. The authors raise the issue as to how to prepare those new to the profession to the changing environment of health science libraries.  相似文献

Introduction

The health care industry is rich in data and information. Web technologies, such as search engines and social media, have provided an opportunity for the management of user generated data in real time in the form of infodemiology studies. The aim of this study was to investigate infodemiology studies conducted during 2002–2016, and compare them based on developed, developing and in transition countries.

Methods

This scoping review was conducted in 2017 with the help of the PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Knowledge, Google Scholar, Wiley and Springer databases were searched between the years 2002 and 2016. Finally, 56 articles were included in the review and analysed.

Results

The initial infodemiology studies pertain to the quality assessment of the hospital's websites. Most of the studies were on developed countries, based on flu, and published in the Journal of Medical Internet Research.

Conclusion

The infodemiology approach provides unmatched opportunities for the management of health data and information generated by the users. Using this potential will provide unique opportunities for the health information need assessment in real time by health librarians and thereby provide evidence based health information to the people.

当前科学教育几种主要价值取向评析   总被引:1,自引:0,他引:1  
20世纪中叶以来,科学技术的迅猛发展,引起了人们社会生活各个方面的极大变革。这种变革对中小学科学教育观念产生了极大的影响,进而导致科学教育的价值取向也随之发生了变化,概括起来目前主要有四种科学教育价值取向,即培养"英才"的科学教育价值取向、人本主义科学教育价值取向、STS教育价值取向和培养学生科学素养的价值取向。  相似文献

IntroductionWhile early commenting on studies is seen as one of the advantages of preprints, the type of such comments, and the people who post them, have not been systematically explored.Materials and methodsWe analysed comments posted between 21 May 2015 and 9 September 2019 for 1983 bioRxiv preprints that received only one comment on the bioRxiv website. The comment types were classified by three coders independently, with all differences resolved by consensus.ResultsOur analysis showed that 69% of comments were posted by non-authors (N = 1366), and 31% by the preprints’ authors themselves (N = 617). Twelve percent of non-author comments (N = 168) were full review reports traditionally found during journal review, while the rest most commonly contained praises (N = 577, 42%), suggestions (N = 399, 29%), or criticisms (N = 226, 17%). Authors’ comments most commonly contained publication status updates (N = 354, 57%), additional study information (N = 158, 26%), or solicited feedback for the preprints (N = 65, 11%).ConclusionsOur results indicate that comments posted for bioRxiv preprints may have potential benefits for both the public and the scholarly community. Further research is needed to measure the direct impact of these comments on comments made by journal peer reviewers, subsequent preprint versions or journal publications.  相似文献

提升我国高职专任师资的实践能力,不仅关系到高职院校核心竞争能力的培育,更关系到当前社会对高技能人才巨大需求与供给矛盾的化解。针对高职专任师资实践能力薄弱的问题,政府、行业、企业和高职院校在加强高职专任师资实践能力建设上,应创新制度设计、加大经费投入、丰富培训资源、加强培训考核评价,以满足高职教育人才培养质量不断提高的新需要。  相似文献

死刑复核程序是我国刑事诉讼中的一道特有程序。自死刑核准权统一收归最高人民法院之后,死刑复核程序的应有功能仍未完全发挥。近期发生的一系列死刑案件更使得死刑复核程序的完善再次成为人们极为关注的话题,死刑复核程序的修改也必将成为刑事诉讼法修改的规划内容之一。  相似文献

This systematic review includes 34 studies examining the effects of school-based physical activity interventions on students' health-related fitness knowledge. The study design, methodological quality, and effectiveness of interventions on students' health-related fitness knowledge were analysed. The majority of the studies (79.4%) revealed significant positive intervention effects on students' health-related fitness knowledge. Studies examining adolescents were more frequently in a position to influence students' health-related fitness knowledge (87.5%) than studies examining children (75%), and studies with low methodological quality (88.8%) had more frequent positive effects than studies with moderate quality (75%). The effects on students' health-related fitness knowledge were independent of moderator variables such as the intervention content, duration and frequency. Only few studies were able to simultaneously positively influence students' health-related fitness knowledge and students' physical activity and/or fitness levels. These programmes can positively influence students' health-related fitness knowledge, but it remains unclear what the practical significance of these changes is. Further research is needed to clarify the influence of students' health-related fitness knowledge on reflection, understanding, physical activity behaviour, and overall physical literacy levels.  相似文献

This article takes a dual focus on the theme of student formative peer assessment. On the one hand it offers a thorough literature review in this field, while on the other it unpacks a case study of curriculum design where peer assessment has been adopted. The practical example draws on recent changes made to a third- and final-year undergraduate research dissertation course in a UK architectural school. Although peer assessment worked quite well in this small setting, similar findings might be uncovered when scaled up to larger cohorts, as well as other disciplines and year groups. The research findings are certainly relevant for other contexts. Qualitative research from a focus group with six students on the course informs the empirical body of the paper. Through engaging with students’ reflections, as well as the relevant literature, and reflexively looking at the curriculum changes, this paper discusses some of the benefits and drawbacks that can arise from peer assessment in this context. Peer assessment is not without its challenges and hiccups, but, despite these, the benefit to autonomous critical thinking cannot be understated. And arguably peer assessment is especially germane for final-year undergraduates as they embark on employment or more advanced studies.  相似文献
