But presumably this is euphemistically attributable to "actuarial turnover"

Will anyone review this paper? Screening, sorting, and the feedback cycles that imperil peer review Scholarly publishing relies on peer review to identify the best science. Yet finding willing and qualified reviewers to evaluate manuscripts has become an increasingly challenging task, possibly even ...

1. Kevin Gross and I just posted a new science-of-science preprint.

This one explores the looming peer review crisis. As many of you know, it's becoming significantly more difficult for journal editors to find scholars willing to serve as peer reviewers for submitted manuscripts.

I absolutely don't love Labour focusing more on not losing voters to the right (on immigration, welfare, etc.) than the left, but a lot of people say stuff like "they are losing 2Γ— as many votes to the Greens" without realising that one vote lost to a party that can overtake you is twice as bad...

Wow! Project Hail Mary is coming to the big screen! I had totally missed that this was coming... Here's hoping it can live up to the book.

@chelseaparlett.bsky.social have you seen?

My model was fitting just fine until I realised my data was only 320 of N=325.

Now it refuses to fit.

When is the next stop so I can get off this train?

This, but also if you are one of the academics that say data are available on request and you have actually provided it on request, go you! (Next time go even further and deposit it so you don't lose it)

Many of my left wing friends and colleagues would be surprised to see me taking this tone, as I am often the centrist dad in the conversation.

And for anyone arguing that private landlords leaving reduces the supply of private rented housing - it also reduces demand (almost) identically.

Absolutely. Many issues with πŸ‡¬πŸ‡§ housing are exacerbated by landlordism, rent-seeking in the truest sense.

I'm almost too angry to put in words all the ways their state-sanctioned greed has impoverished the nation. The situation can only improve by them rage-quitting.

Abject market failure.

The Editorial Boards of leading health economics journals are issuing a Joint Statement of Principles on Editorial Independence. In these troubled times some scholars worry their work might suffer ideological attack. We reaffirm our commitment to unfettered scholarship. Please repost.

The UK government must step in to protect jobs in #HigherEducation.

Voluntary and compulsory redundancies throughout the sector.

Staff costs have been squeezed for years - the sector needs cash. Either bring back international students, raise tuition fees, or reinstate block funding... Do it fast!

There is an academic theoretical paper I keep coming back to, and every time I read it I can't work out if I'm really dumb or the authors are really dumb...

No, I will not say which paper it is!

I am more enthusiastic than most for frailty models. When so much analysis outside survival analysis uses random effects it baffles me that we don't.

I think they have great explanatory power for things like accelerating then decelerating hazard at the population level.

For general survival analysis (not just parametric models) the Stata documentation st intro is great. Most of these are free online for slightly out of date versions.

Stata PDF documentation for streg is pretty good. If you want something with more maths the 3 page primer by Peter Treasure of Cambridge you can find by searching for "individual frailty gamma" is also good.

US has suspended all military aid to Ukraine, White House official says, in wake of Trump-Zelenskyy row Decision affects ammunition, vehicles and other equipment including weapons in transit

Trump has no interest in peace, he only wants Zelenskyy to lose and Putin to win. Next step will be undoing sanctions on Russia. The US has truly switched sides, and it probably all originates from Zelenskyy not helping Trump screw Biden in 2020 election.

Trump is a dangerous & ridiculous hypocrite.

Zelenskyy declared martial law because Ukraine was invaded. He wants to declare martial law because people have pronouns and there are undocumented migrants.

Only one of them is a dictator, and he's in the role we used to call leader of the free world.

Indeed, what they want is mob rule. Majoritarian if possible, but if not they are very happy to also be a mob-ruling minority oppressing everyone who is not them.

A democracy is more than elections. Rule of law is a perquisite, pluralism a strength.

To make UK higher education significantly more progressive, scrap fees in favour of a graduate tax and make the unit of resource for universities higher for home UG students from more deprived backgrounds.

Squeezed in 20 minutes this evening... I'm working on coding a stripped down version of the beautiful game Forest Shuffle.

It's got some fun features (lots of the cards are "split" and you choose which half to play) but also interactivity between players is limited (no stealing, peeking, etc.)
