Last week I presented at the STI-ENID 2026 in Antwerp on comparing Scopus and OpenAlex for measuring international researcher mobility. The main finding: the choice of database changes not just how much mobility you measure, but who counts as mobile.

An analysis by Najko Jahn on the coverage of affiliation data from #OpenAlex in November 2025 showed an unexpected decline. Now, #KB's Paul Donner and Marion Schmidt wanted to see if the problems were solved (spoiler: mostly). Our analysis can be read on open-bibliometrics: tinyurl.com/mrxxnsyw.

It seems that the decline in disruption papers and patents reported in the well-known 2023 Nature paper is partly due to artefacts in the dataset and a software bug. www.nature.com/articles/s41...

Paying peer reviewers works. Expanded Fast & Fair experiment @biologyopen.bsky.social: • 5.5 vs 37.7 working days to decision with reviews • ~3 vs ~9 reviewer invitations per manuscript • no reduction in editor-assessed review quality • similar acceptance rates www.biorxiv.org/content/10.6...
Scatter plot showing that Fast & Fair peer review reached first decision with reviews much faster than conventional peer review: mean 5.5 versus 37.7 working days. Most Fast & Fair manuscripts met the 7-working-day target, while conventional manuscripts were slower and more variable, up to 116 working days.

OpenAlex is increasingly used as an open alternative to proprietary bibliometric databases, but an important question remains: how reliable is its institutional affiliation data?

📢 New reviewed preprint, published by @elife.bsky.social at doi.org/10.7554/eLif.... We study two effects in science funding across 14 different funding programmes from 6 research funders across Europe and North America: (1) The Matthew effect; and (2) and the early-career setback effect. 🧵1/8
Illustration of the Matthew effect and the early-career setback effect. An academic, say Alice, first applies for early-career funding in 2015. She received early-career funding, and goes on to reapply for later-career funding in 2020. According to the Matthew effect, the chances of Alice receiving later-career funding is higher when she received early-career funding. Alice showed a high Mean Field Citation Rate (MFCR) before receiving her early-career funding, and similarly a high MFCR in between the early-career and later-career applications. According to the early-career setback effect, had she instead not received funding, her "Between" MFCR would have been higher. We not only study the "Between" MFCR, we also study the MFCR after the early-career application ("Post (early)") and after the later-career application ("Post (later)").

Knowledge lost, parity gained? COVID-19 and gender gaps in Dutch academia - Scientometrics
We investigated the extent to which the COVID-19 pandemic impacted long-standing gender inequalities in Dutch academia. Dutch academia is an ideal case to gain insight on exacerbated gender differentials due to COVID-19 on employees, because men and women face comparable institutional contexts and any COVID-19 impact becomes visible and measurable fast through potentially decreased yearly publications. We reconstructed the complete publishing careers up till 2022 of more than 8000 Dutch scientists who received a PhD from 1990 onwards and still had an active publication career before the pandemic started. We compared the publication dip between men and women during COVID-19. Our data allowed us to investigate whether the gendered impact of COVID-19 varied across research domains, different PhD cohorts and type of research output. We consistently find that COVID-19 did not have more severe consequences on research output for women than for men.
