Using an intuitive and theoretically warranted assumption, we find a declining period trend 📉. The bounding approach offers a clear and assumption-aware alternative to other approaches. 🔓 Materials for reproducibility available here:

Sorry, I didn’t link to the right comment. More than the fake reviews, what I got from the discussion there was concern about uploading a preprint without a licence to a site where it’s not really clear who you’re submitting it to.

Reviews of studies on the drop in youth offending finds consistent decreases across many countries ended around 2015, and the drop is best explained by changes in how young people spend free time and decreases in alcohol consumption.

Prestige over merit: An adapted audit of LLM bias in peer review Large language models (LLMs) are playing an increasingly integral, though largely informal, role in scholarly peer review. Yet it remains unclear whether LLMs reproduce the biases observed in human de...

Yet again, machine learning — even gussied up via the transformer architecture — encodes and reinforces societal biases.

This study reveals that LLM-based peer review relies heavily on author institution in its decisions.

🚨 It's been a long time in the making, but I'm happy it's finally out!

Standing on the shoulders of giants, in this preprint we propose an avenue for theoretical development in the field of environmental (cyber)criminology with practical applications for crime analysis.

Tile chart showing 36 barriers to practicing open science, grouped by barrier type and by open science practice. The five barrier categories, based on National Academies of Sciences, Engineering, and Medicine (2018), are: costs and infrastructure (3 barriers); structure of scholarly communications (8); lack of supportive culture, incentives, and training (15); privacy, security, and proprietary barriers to sharing (8); and (intra)disciplinary differences (2). Barriers are also grouped by nine open science practices: publishing open access (4 barriers), publishing preprints (5), sharing open code (4), sharing open data (6), sharing open materials (2), conducting open peer review (4), using open source software (4), pre-registering research (3), and disclosing contribution roles (4).

Researchers often perceive 'barriers' to practicing #OpenScience, whether it’s publishing open access, sharing data, or pre-registering studies.

Last week at @esc-eurocrim.bsky.social, I presented our work at NSCR identifying 36 such distinct barriers.

Do you recognize them in your own work?
