Could scientists use Altmetric.com scores to predict longer term citation counts?     

Mike Thelwall  Tamara Nevill 《Journal of Informetrics》2018,12(1):237-248

Altmetrics from Altmetric.com are widely used by publishers and researchers to give earlier evidence of attention than citation counts. This article assesses whether Altmetric.com scores are reliable early indicators of likely future impact and whether they may also reflect non-scholarly impacts. A preliminary factor analysis suggests that the main altmetric indicator of scholarly impact is Mendeley reader counts, with weaker news, informational and social network discussion/promotion dimensions in some fields. Based on a regression analysis of Altmetric.com data from November 2015 and Scopus citation counts from October 2017 for articles in 30 narrow fields, only Mendeley reader counts are consistent predictors of future citation impact. Most other Altmetric.com scores can help predict future impact in some fields. Overall, the results confirm that early Altmetric.com scores can predict later citation counts, although less well than journal impact factors, and the optimal strategy is to consider both Altmetric.com scores and journal impact factors. Altmetric.com scores can also reflect dimensions of non-scholarly impact in some fields.  相似文献   

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers     

Zhigang Hu  Wencan Tian  Shenmeng Xu  Chunbo Zhang  Xianwen Wang 《Journal of Informetrics》2018,12(4):1133-1145

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.  相似文献

The Impact of Workplace Bullying on Primary School Teachers and Principals     

Declan Fahie  Dympna Devine 《Scandinavian Journal of Educational Research》2014,58(2):235-252

While previous research has consistently cited education as a high risk profession for negative workplace relationships, there has been little consideration of the impact of workplace bullying for those involved. This paper seeks to address this lacuna through the analysis of 24, in-depth interviews with self-identified victims of workplace bullying who work, or have worked, in primary schools. The study reveals the profound physical, psychological, social, and economic effects of these toxic behaviors upon the interviewees, along with the resistance strategies they employed to help them cope with their experiences. Through a lens of Foucauldian conceptualisation of power, this study explores the broader implications for school organizational culture, as well as for individual teachers and the pupils they teach.  相似文献   

我国体育行政执法方式改革研究          下载免费PDF全文

梁尧 《体育科研》2019,(4):67-74

新时代对体育强国和体育法治建设提出了新要求，行政执法作为体育强国建设的重要抓手也面临着方式革新的机遇和挑战。简政放权背景下，体育执法面临着“应不应该管、怎样管”的尴尬处境，广为体育行政执法主体运用的强制性执法手段极易加剧执法矛盾，执法的社会效果得不到保障。由于传统执法方式难以适应新时代体育市场监管的现实需要，革新体育行政执法方式就显得尤为必要。面对时代课题，应遵照由“形式优化”到“实质革新”的逻辑，并树立行政平衡、服务合作和正当程序的理念，从引入信用工具、推广非强制性执法和全程说理式执法3个方面推进改革，实现体育行政执法方式的精简化、多元化和法治化。  相似文献
