Research and development activities are regarded as one of the most influencing factors of the future of a country. Large investments in research can yield a tremendous outcome in terms of a country’s overall wealth and strength. However, public financial resources of countries are often limited which calls for a wise and targeted investment. Scientific publications are considered as one of the main outputs of research investment. Although the general trend of scientific publications is increasing, a detailed analysis is required to monitor the research trends and assess whether they are in line with the top research priorities of the country. Such focused monitoring can shed light on scientific activities evolution as well as the formation of new research areas, thus helping governments to adjust priorities, if required. But monitoring the output of the funded research manually is not only very expensive and difficult, it is also subjective. Using structural topic models, in this paper we evaluated the trends in academic research performed by federally funded Canadian researchers during the time-frame of 2000–2018, covering more than 140,000 research publications. The proposed approach makes it possible to objectively and systematically monitor research projects, or any other set of documents related to research activities such as funding proposals, at large-scale. Our results confirm the accordance between the performed federally funded research projects and the top research priorities of Canada. 相似文献

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

Data-driven innovation (DDI) gains its prominence due to its potential to transform innovation in the age of AI. Digital giants Amazon, Alibaba, Google, Apple, and Facebook, enjoy sustainable competitive advantages from DDI. However, little is known about algorithmic biases that may present in the DDI process, and result in unjust, unfair, or prejudicial data product developments. Thus, this guest editorial aims to explore the sources of algorithmic biases across the DDI process using a systematic literature review, thematic analysis and a case study on the Robo-Debt scheme in Australia. The findings show that there are three major sources of algorithmic bias: data bias, method bias and societal bias. Theoretically, the findings of our study illuminate the role of the dynamic managerial capability to address various biases. Practically, we provide guidelines on addressing algorithmic biases focusing on data, method and managerial capabilities. 相似文献

高考政策属于国家的公共政策。作为高校招生考试,高考应该坚持高等教育领域的国家利益优先性,但因为高考政策同时涉及为高校输送新生的基础教育领域的国家利益,而且基础教育领域的国家利益比高等教育领域的国家利益影响更为广泛、更为久远,所以高考政策应在为高校选拔新生的同时,坚持基础教育领域的国家利益优先。但现实却是,有些高考政策使基础教育领域的国家利益优先性体现不充分。这就要求高考政策进行必要的、及时的改革。 相似文献

政策文件替代计量指标作为一种相对较新的指标,为测度学术成果的社会影响力提供了新方向,具有很高的研究价值。本文基于Altmetric.com公司从2013年1月到2016年6月收集到的所有政策文件替代计量指标数据9万余条,通过统计分析揭示其分布特征,旨在为进一步研究提供基础。研究发现,政策文件替代计量指标的相对覆盖率较低,为1.7%;相对引文指标没有及时性优势,平均时滞长达4.5年;论文层次的分布较为均匀,94%的学术成果仅有1条政策文件提及;期刊层次的分布基本遵循布拉德福定律,EFSA Journal等核心期刊是政策文件参考的主要学术成果来源;保健科学和医学是政策文件提及最多的学科,占据了“半边江山”;具有政策文件替代计量指标的学术成果,其替代计量关注度指数总体处于中等偏上水平,没有明显优势。图7。表5。参考文献19。 相似文献

The aim of this research is to achieve a better understanding of the processes underlying knowledge transfer (KT) in social sciences and humanities (SSH). The paper addresses: first, the extent of SSH research groups’ engagement in KT and the formal KT activities used to interact with non-academic communities; and second, how the characteristics of research groups may influence engagement in various types of KT. The empirical analysis is at research group level using data derived from a questionnaire of SSH research groups belonging to the Spanish Council for Scientific Research (CSIC). We find that KT activities are based on relational rather than commercial activities. The most frequent relational activities in which SSH research groups engage are consultancy and contract research. We find also that the characteristics of research groups (e.g. size and multidisciplinarity) and individuals (e.g. academic status and star scientist) are associated with involvement in KT activities and that a deliberate focus on the societal impacts and relevance of the research conducted is strongly related to active engagement of research groups in all the modes of KT considered in this study. From a managerial perspective, our findings suggest that measures promoting a focus on the societal impact of research could enhance research groups’ engagement in KT activities. 相似文献
