- This is a new preprint on the impact of the COVID-19 pandemic on international researcher mobility. The analysis estimates approximately 14,700 fewer international researcher movements between 2020 and 2022 than expected, corresponding to a global loss of about 3.7%. osf.io/preprints/so...

- Reposted by Andrey LovakovExplainers & tutorials are a great way to criticize current practices with a positive twist. Tailoring them to a specific substantive (!) subfield can greatly increase uptake. Forget about novelty; if some statistican said sth in the 70s but no one was around to hear it, say it again.>

- Reposted by Andrey LovakovThere seems to be a decrease in the coverage of affiliation metadata in #OpenAlex, particularly with regard to journal articles published by Elsevier since 2024.

- A total of $8.349 billion were spent on APCs between 2019 and 2023. In 2023 MDPI ($681.6 mln), Elsevier ($582.8 mln) and Springer Nature ($546.6 mln) generated the most revenue with APCs. Annual spending almost tripled from $910.3 million in 2019 to $2.538 billion in 2023: arxiv.org/abs/2407.16551
