I scraped unpublished manuscripts from bioarxiv and injected half of them with a hidden prompt. I then asked three LLMs to review the paper - in half cases I told the LLM to check for prompt injections. 📈 Prompt injections lead to more recommendations 📉 Prompt checks eliminated this effect

Generative AI is nearly 5 times less accurate than humans. "In a direct comparison of LLM-generated and human-authored science summaries, LLM summaries were nearly five times more likely to contain broad generalizations (OR = 4.85, 95% CI [3.06, 7.70])." royalsocietypublishing.org/doi/10.1098/...

Hello Bluesky, I guess I should introduce myself. I'm Jack, I enjoy bibliometrics and Open Science research. When I have time I'm also pursuing my PhD. I created the Open Research Converter (the ORC) orc-demo.gesis.org, and looked at the reference coverage of OpenAlex arxiv.org/abs/2401.16359.

My analysis based on cross-country panel data shows that academic freedom at the country level is associated with the future citation impact of papers by researchers from a country. The higher the level of AF, the higher the citation impact of papers published 3 y later: zenodo.org/records/1416...

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

Why summing up bibliometric indicators does not justify a composite indicator Psychometric measurement concepts were applied to bibliometric composite indicators. Some indicators of the Ioannidis et al.’s (2020) composite do not fit well: link.springer.com/article/10.1...

Several journals have been instituting a submission and reviewing break over the summer. It's a nice idea to promote a healthy work-life balance. But PsyArXiv preprint submissions suggest the best time for this is Christmas break, with a 50% drop in preprints.
