[Academic.com scores can be used to help predict future citation counts, especially if the Mendeley reader component is included. Considering both Altmetric.com scores and journal impact factors gives the best predictions. Altmetric.com scores also seem to partly reflect non-scholarly impact dimensions in some fields.]

Are Mendeley reader counts useful impact indicators in all fields?Scientometrics, 113(3), 1721–1731. doi:10.1007/s11192-017-2557-x [Correlations between Mendeley reader counts and Scopus citation counts are strong in almost all of 325 narrow Scopus fields checked, so Mendeley reader counts are an almost universally strong citation impact indicator.]

Figshare: A universal repository for academic resource sharing?Online Information Review, 40(3), 333-346. doi:10.1108/OIR-06-2015-0190 [The repository FigShare host resources from some subject areas more than others but the uptake of its resources does not depend on their subject area.]

Journal of the Association for Information Science and Technology, 68(2), 468-479. doi:10.1002asi.23675 [Article views in ResearchGate have a significant positive correlation with Scopus citations but seem to reflect a wider audience than scholarly citations.]

Journal of the Association for Information Science and Technology, 57(6), 3036-3050. doi:10.1002/asi.23559 [Mendeley reader counts increase more quickly than do citation counts across many different areas of research and stabilise after about five years. Coupled with high correlations between Mendeley readers and citations, this confirms the value of Mendeley reader counts as early evidence of impact for research.]

Journal of the Association for Information Science and Technology, 67(5), 1198-1209. doi:10.1002/asi.23477 [Based on a survey of Mendeley users, articles are bookmarked in Mendeley mainly because they have been read or intend to be read. Hence Mendeley bookmarks can be used as indicators of readership for articles, at least for Mendeley users.]

Journal of the Association for Information Science and Technology, 67(3), 566-581. doi:10.1002/asi.23404.[Introduces Amazon book reviews (number and sentiment) as metrics for academic book impact.

Chapter summary: Gender is important for understanding attitudes to privacy in the social web because of the many gender-related privacy differences. In general, women are more concerned about privacy than men but nevertheless publish more personal information in blogs and social network sites. The root causes of the differences seem to lie in socialised gendered communication strategies and privacy-related issues that disproportionately concern women. This chapter reviews evidence for gendered online communication and privacy concerns, focusing mainly on blogs, social network sites and YouTube, and includes a special section on LGBT issues.
