Instead of suffering in silence, let’s share them. We’d love to hear your stories, opinions, comments—or, in rare and glorious cases, actual solutions.

We've got ISSUES. Literally.
We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do?

Really comprehensive but digestible. Consider sharing it with your students. I will.
I just created a series of seven deep-dive videos about AI, which I've posted to youtube and now here. 😊
Targeted to laypeople, they explore how LLMs work, what they can do, and what impacts they have on learning, well-being, disinformation, the workplace, the economy, and the environment.

Has anyone of you lovely folks experience with sample size justifications for ordinal models and/or beta models (zero/one inflated)?
Problem is that these models take a while to fit with Bayesian models, so a simulation-based approach is not feasible...

Or as I often say: Friends don't let friends use abbreviations!
An abbreviation (ABB) in a journal article (JA) or Grant Application (GA) is rarely worth the words it saves. Every ABB requires cognitive resources (CR) and at my age by the time I'm halfway through a JA or GA I no longer have the CR to remember what your ABB stood for.
