Altmetrics have been proposed as a way to assess the societal impact of research. Although altmetrics are already in use as impact or attention metrics in different contexts, it is still not clear whether they really capture or reflect societal impact. This study is based on altmetrics, citation counts, research output and case study data from the UK Research Excellence Framework (REF), and peers’ REF assessments of research output and societal impact. We investigated the convergent validity of altmetrics by using two REF datasets: publications submitted as research output (PRO) to the REF and publications referenced in case studies (PCS). Case studies, which are intended to demonstrate societal impact, should cite the most relevant research papers. We used the MHq’ indicator for assessing impact – an indicator which has been introduced for count data with many zeros. The results of the first part of the analysis show that news media as well as mentions on Facebook, in blogs, in Wikipedia, and in policy-related documents have higher MHq’ values for PCS than for PRO. Thus, the altmetric indicators seem to have convergent validity for these data. In the second part of the analysis, altmetrics have been correlated with REF reviewers’ average scores on PCS. The negative or close to zero correlations question the convergent validity of altmetrics in that context. We suggest that they may capture a different aspect of societal impact (which can be called unknown attention) to that seen by reviewers (who are interested in the causal link between research and action in society). 相似文献

Searching for randomised controlled trials and clinical controlled trials in Thai online bibliographical biomedical databases 总被引:1,自引:1,他引:0
Background: Thailand is a poor but highly literate country in South‐East Asia with over 60 million people. A lot of biomedical research is undertaken but dissemination is limited. Objectives: To identify relevant Thai bibliographic databases and investigate accessibility, functionality and content, particularly in relation to randomised controlled trials (RCTs) and clinical controlled trials (CCTs). Methods: A systematic search for institutions productive of research and the databases in their libraries. Search each accessible database in both Thai and English, recording the functionality and content. Assess accessibility of the retrieved RCTs or CCTs by comparing to Pub Med holdings. Results: We found 32 different databases (29 accessible in UK) of various sizes, coverage and functionality but many with unique records of RCTs and CCTs (total, n = 781). Two hundred and nine of 781 trials were accessible on Pub Med (27%). However, 641 of the 781 trial records contain text in both English and Thai (82%) and 112 records were solely English (14%). Conclusions: Those undertaking comprehensive searches for RCTs/CCTs should, in addition to a Pub Med , search the Thai Medical Index and Thai Index Medicus databases, and the Khon Kaen University Library Catalogue. 相似文献

This paper is an attempt to describe the nature and scope of educational provision in Tanzania since 1967. It focusses on the implications of educational policy for the development of manpower which would be suited to the satisfaction of basic needs in rural areas.Tanzania since 1967 is reportedly attempting to implement what amounts to a basic needs strategy of development in line with the declared socialist objectives of the Government.This strategy is essentially a mixture of poverty and employment oriented strategies directed at satisfying essential human needs in areas such as health, education, safe water, housing and sanitation, and food supply as well as other requirements for a fully productive life.Although the provision of education is itself a basic need, it is also a vehicle for the production of trained manpower which is essential to the effective implementation of the basic needs strategy in the other sectors mentioned above. This paper presents preliminary and tentative impressions of the relevance of Tanzania's educational system to the Government's objective of meeting the basic needs of its people as soon as possible.The paper is divided into four sections: educational philosophy in Tanzania, educational growth and development, manpower implications and theoretical models explaining the development of educational resources in Tanzania since 1967.It concludes that, where planning has preceded political decisions, large measures of success have been achieved, but that, overall, political expediency and haste have created substantial divergences between policy and practice. 相似文献

This paper builds on Leslie Morton's vision of enabling users through education and training. It describes three different approaches to mediated training for medical students and clinicians provided by peers, juniors (i.e. medical students) and information specialists (i.e. clinical librarians) and considers the benefits to the participants. The training was provided either on a one-to-one basis or within teams in their work environments (e.g. offices, wards, team meetings). The first two projects (peer tutoring and reverse mentoring) suggest that contextualized training, using intermediaries, provides the direct benefit of cost-effective IT skill development and the indirect benefits deriving from the interactions between the trainers and the target groups. The third project, the outreach librarian study, provides evidence of both direct benefits (i.e. time saved, quality of service, skills acquired, financial savings and improved evidence-based medicine implementation) and indirect, long-term benefits relating to more social issues (e.g. perceptions of the library, clinical teams, job satisfaction and patient interactions). The general conclusion to emerge from this review of case studies is that the concept of educational benefits is very broad and that empirical studies need to look at both obvious and less obvious benefits. 相似文献
