Papers mills and other manipulative practices are a major problem in the scientific publishing system. Addressing this problem requires an in-depth system-level understanding of dynamics leading to these practices. At @cwts we have PhD position to work on this! https://www.universiteitleiden.nl/en/vacancies/2025/q2/15601-phd-candidate-paper-mills-and-systematic-manipulation-in-research-publishin

#WebOfScience just announced that it has started to index preprints in addition to journal articles https://clarivate.com/blog/the-preprint-citation-index-linking-preprints-to-the-trusted-web-of-science-ecosystem/. This is a significant development toward giving full recognition to preprints as important research outputs. Together with @cwts colleague @neesjanvaneck, I&#39;m working on a blog post comparing indexing of preprints in Web of Science with other bibliographic databases. Stay tu...

I just had the pleasure of being invited to comment on the excellent report &#39;Can REF output quality scores be assigned by AI? Experimental evidence&#39; by Mike Thelwall and colleagues http://cybermetrics.wlv.ac.uk/ai/Can_REF_output_quality_scores_be_assigned_by_AI.pdf. I offered four brief reflections, commenting on what I think are key issues in the use of AI for research assessment purposes, in particular in the context of the UK REF. @RoRInstitute @jameswilsdon

In last Friday&#39;s @cwts seminar Diana Hicks offered a critical perspective on open science. I couldn&#39;t attend, but just watched the recording https://www.cwts.nl/seminars/announcements?article=n-s2y264. Reform movements in science (RRA, OS, EDI, etc.) tend to develop dogmas that are being accepted uncritically. Good to see critical analyses like Diana&#39;s that challenge these dogmas. However, many of Diana&#39;s arguments don&#39;t really convince me, and they som...

Interesting results in @digitalscience and @springernature #StateOfOpenData report https://doi.org/10.6084/m9.figshare.24428194.v1. This graph shows a breakdown by field of the openness of survey respondents to four open science practices. The pattern is almost the same for all fields: Researchers are most strongly in support of open access, followed by open data, then open peer review and finally preprinting.
