Show moreAltmetric’s mission is to help others understand the influence of research online.We collate what people are saying about published research in sources such as the mainstream media, policy documents, social networks, blogs, and other scholarly and non-scholarly forums to provide a more robust picture of the influence and reach of scholarly work. Altmetric works with some of the biggest publishers, funders, businesses and institutions around the world to deliver this data in an accessible and reliable format.ContentsAltmetrics, Ten Years Later, Euan Adie (Altmetric (founder) & Overton)Reflections on Altmetrics, Gemma Derrick (University of Lancaster), Fereshteh Didegah (Karolinska Institutet & Simon Fraser University), Paul Groth (University of Amsterdam), Cameron Neylon (Curtin University), Jason Priem (Our Research), Shenmeng Xu (University of North Carolina at Chapel Hill), Zohreh Zahedi (Leiden University)Worldwide Awareness and Use of Altmetrics, Yin-Leng Theng (Nanyang Technological University)Leveraging Machine Learning on Altmetrics Big Data, Saeed-Ul Hassan (Information Technology University), Naif R.

Show moreThe aim of this paper is to demonstrate how topical distance and social distance can provide meaningful results when analysing scholars’ tweets linking to scholarly publications. To do so, we analyse the social and topical distance between tweeted information science papers and their academic tweeters. This allows us to characterize the tweets of scientific papers, the tweeting behavior of scholars, and the relationship between tweets and citations. Show less

Show moreIn this preliminary study, we investigate the influence of scholarly content sharing on two different social media platforms on paper clicks. Based on the clicks data of short links embedded in the social media posts, we quantify the performance from a novel perspective that has been underexplored by previous altmetrics studies. We select 162 papers published in Cell from October 2016 to May 2018 and investigate the scholarly content posted on Twitter and Facebook by the journal. We collect social media acts data depending on the affordances of these platforms, including retweets, likes, reactions, and shares; moreover, we collect the short links in the posts and the link metrics data. Our results show that in absolute terms, scholarly Facebook posts sharing scholarly content have higher clicks than similar tweets. The number of Facebook reactions and shares are four and 2.5 times of Twitter likes and retweets, respectively. Moreover, the click metrics of short links show that posts on Facebook have directed twice as much readers to the papers as posts on Twitter. However, the true exposure effect of the two platforms is similar when the difference of total followers between the two platforms are eliminated. The regression analysis suggests that social media engagement has positive effects on directing users to the papers. Whether reactions and shares on Facebook or likes and retweets on Twitter would affect the clicks of the short links. Show less

Show moreThe newly released refine option of Open Access on the Web of Science platform makes it possible to analyze the article-level OA content across the whole Web of Science database, including more than sixty million documents. In this study, employing the OA filter option of Web of Science, we perform a large-scale evaluation of the OA state of countries from 1990 to 2016. Particularly, for each country, we consider not only the absolute number of Gold OA literature but also the ratio of them among all literature. We compare the rates and evolutions of OA across countries. Our results show that the number of OA articles have increased quickly in the last decades. Currently, one quarter of the Web of Science articles are Gold OA articles; In contrast, in 1990, the percentage of OA articles is less than 8%. Brazil is found to be the most active country in OA publishing. In contrast, Russia, India and China have the lowest OA ratios. In addition, the temporal trend analysis shows that the OA percentage of Brazil has been decreasing dramatically in recent years, while the OA percentages of China, UK and Netherlands have been increasing.

Show moreMethylation of the 5'-cap structure of viral RNAs plays important roles in genome replication and evasion of innate recognition of viral RNAs by cellular sensors. It is known that coronavirus nsp14 acts as an N7-(guanine)-methyltransferase (MTase) and nsp16 as a 2'-O-MTase, which are involved in the modification of RNA cap structure. However, these enzymatic activities have not been shown for any other nidoviruses beyond coronaviruses in the order Nidovirales. In this study, we identified a 2'-O-methyltransferase encoded by ronivirus that shows common and unique features in comparison with that of coronaviruses. Ronivirus 2'-O-MTase does not need a protein cofactor for MTase activity, whereas coronavirus nsp16 needs the stimulating factor nsp10 for its full activity. The conserved K-D-K-E catalytic tetrad is identified in ronivirus 2'-O-MTase. These results extend our understanding of nidovirus RNA capping and methylation beyond coronaviruses and also strengthen the evolutionary and functional links between roniviruses and coronaviruses.
