Automated university systems ‘make administrative burden worse’ Risk-averse mindset, fervour for meetings and ‘time sink’ labour-saving ploys leave everybody overburdened, finds Melbourne study

Automated systems are “a complete and utter nightmare” for university staff, exacerbating rather than easing administrative burdens by trapping academics in a logjam of service requests, an Australian survey has found

Honestly what a useless government.

🚨 UK universities are giving everyone a 2.1% real terms pay cut, as VCs take an average £340,000. A 1.4% "uplift" when inflation is 3.5%.

📉 Worse, UCU's incumbent has no vision, no strategy, no ability to explain the rip-off, after real term cuts over 25% since 2010👇

Concentration Camp Labor Cannot Become Normal

"With the passage of Trump's death bill, we face the prospect of many great harms, including an archipelago of concentration camps across the United States."

I don’t think anyone is prepared for what they just did w/ ICE.

This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.

It is setting up to make what’s happening now look like child’s play. And people are disappearing.

The UK also does not know how ventilation works. Most windows only open a crack and there's no forced air. It can get much warmer inside a building than outside.

Uff

Just trying to understand the implications, 2026 is between runs, so hopefully things get better by O5?

From the talk at APS, just now.

And all of this is helping to drive the financial crises unfolding at UK universities.

Two Weeks In The Death Spiral Of Cardiff University - Reading Time: 4 minutesBy an anonymous academic. Cover image by Adwitiya Pal On the second day of classes…

Two Weeks In The Death Spiral Of Cardiff University, by an anonymous academic.
This is truly shocking read.
The Cardiff executive board should hang their heads in shame.

Congrats Bob! A great supervisor too!

As an academic, reading this made me realize that private businesses have things like free coffee.

As someone who has reported on AI for 7 years and covered China tech as well, I think the biggest lesson to be drawn from DeepSeek is the huge cracks it illustrates with the current dominant paradigm of AI development. A long thread. 1/

The loss is a bit fictitious no? Even if grants are only funded at 80%, there is still a huge amount of overhead that is covered.

Scientific poster with dark-blue background. Title: Flow Annealed Importance Sampling Bootstrap meets differentiable particle physics. The poster contains multiple sections: Generation of data in particle physics, normalizing flows, training approaches, and results for a 2D distribution (lambda_c^+ decay) and a 8D distribution (top production). Additionally, results for the efficiency over the number of target evaluations are shown.

Nihar analyzed a large number of public LVK events. The models are expensive, making the study impossible using conventional techniques. Instead, Nihar used our simulation-based inference code, DINGO, which uses neural networks for rapid results. He double checked results using importance sampling.

Posterior probability distributions for three GW events (GW190701, GW200129, GW200208), showing nonzero eccentricity.

🔑 Main result: We find evidence that three GW events—GW190701, GW200129, GW200208—are eccentric. This is shown in their posterior probability distributions, where the eccentricity parameter is well away from zero. These plots compare observational data to our theoretical models.

🚨This paper led by @nihar-gupte.bsky.social has gone somewhat under the radar since posting, but it deserves attention:
* It's the first paper to provide solid evidence for eccentricity in three LIGO-Virgo-KAGRA black hole binaries.
* It was only possible thanks to AI-accelerated inference tools.
