Wikipedia on KWS which does the age verification (at least for bluesky):
- it's a subsidiary of EPIC GAMES
- the highly private and sensitive data would likely to go a new company if this company was sold ^^

Looks like Australia's social media ban came into effect. Age verification appears based on 1) facial scan age estimation or 2) ID scan. This in turn appears to be done by third party companies, so opens doors to privacy issues / leaks.
Also, what exactly was the evidence base for this ban again?

Also looked at the depression anxiety example, I think it's mathematically necessary you get that behavior: if cor(x1,x2)=0.7, and you remove x1 and x2 from each other and correlate what is left, you get negative cor.
Brief sim (varying original correlation, n=500 each, 100 runs each).

Marcel found it — it is not where it is in the pdf (between the end of the paper and the beginning of the bibliography), but hidden in a separate view under "author information" which opens some new window called "Funding Information" that is not searchable from the main window.

When you ctrl-cmd f for "conflicts" or anything related to this, it does not show. I don't understand this is not part of the main text between "conclusions" and "references" in the same way it is for the PDF (pink arrow html view), but hidden where you expect author affiliations, not COI.

In the 2021 'international expert opinion' Ketamine paper, 19/25 authors have a combined 2100 words of conflicts of interests.
html version of paper does not show COI, PDF does.
Is that not a massive problem?

Results are complex & depend on the purpose you want to use EMA for.
Shoutout to the fantastic, highly interdisciplinary author team, with a special thanks to the amazing @aaron.bsky.team for making his awesome EMA dataset public which we used for this paper in addition to our WARN-D data.

NL funder NWO recently changed rules for grant applications to endorse more modern recognition & reward practices.
But in my reading, the updated preproposal rules (CV, output, & just the slightest teensy weensy hint of a research idea) fully lean into Matthew effect.
Thoughts?

Anyone planning to go to APS 2026 working on clinical prediction models? We have a nice preprint on predicting depression severity in n~1700 using smartphone & smartwatch data, and would love to join a symposium or help putting one together :)

Hey @cos.io, boomer here cannot figure out how to update my files on the OSF after the recent changes.
It used to be drag and drop over the files (see here dragging the supplementary.pdf) but that doesn't work, and the "edit" button is only for the wiki.
