Using Geographic Momentary Assessment to Explore Spatial Environment Influences on Wellbeing in People With HIV - AIDS and Behavior
Place-based socio-economic and racial inequities contribute to health disparities among people with HIV (PWH). We used geographic ecological momentary assessment (GEMA) methodologies to explore the in...

Relatedly, I’m seeing absurd inflation of on-demand expert annotation - clickwork requiring advanced degrees, essentially - as “Research Scientist” and “Postdoctoral Fellow” positions and it’s twisting me into a gatekeeper for our ECR titles.
I need all the startups in this crowded space to understand that academics do this kind of work for free or very little money *for academia*. Subsidizing your for-profit endeavor is not in my career plan.

We need to bring back “backwards” as a haymaker insult. Because that’s what craven rejection of flourishing urbanity is: backwards shit for cynics and rubes.
Completely unoriginal thought but: it's frustrating that the actual experience of living in large cosmopolitan multicultural city (London Uk in my case) is actually pretty dope, but a lot of politics is organised around this being a nightmare scenario that must be apologised for and avoided.

I had complicated feelings toward marriage equality for a bit. But when I got gay married myself, I became misty-eyed at the “Spouse A” and “Spouse B” designations at the Manhattan City Clerk’s Office. Witnessing blazing societal progression boiled down into administrative humdrum; it felt so real.

In the early 2000s, I had a pretty decent dirtbag cellphone by keeping a pink plastic pager, a refillable phone card, and knowing where all the payphones were in my neighborhood.

Fantastic mechinterp paper showing that you can identify specific neurons which cause hallucinated answers in LLMs, and that these neurons are specifically associated with the language model trying to follow instructions too hard.

H-Neurons: On the Existence, Impact, and Origin of Hallucination-Associated Neurons in LLMs

HTML (experimental)
Large language models (LLMs) frequently generate hallucinations -- plausible but factually incorrect outputs -- undermining their reliability. While prior work has examined hallucinations from macroscopic perspectives such as training data and objectives, the underlying neuron-level mechanisms remain largely unexplored. In this paper, we conduct a systematic investigation into hallucination-associated neurons (H-Neurons) in LLMs from three perspectives: identification, behavioral impact, and origins. Regarding their identification, we demonstrate that a remarkably sparse subset of neurons (less than of total neurons) can reliably predict hallucination occurrences, with strong generalization across diverse scenarios. In terms of behavioral impact, controlled interventions reveal that these neurons are causally linked to over-compliance behaviors. Concerning their origins, we trace these neurons back to the pre-trained base models and find that these neurons remain predictive for hallucination detection, indicating they emerge during pre-training. Our findings bridge macroscopic behavioral patterns with microscopic neural mechanisms, offering insights for developing more reliable LLMs.

Sorry to harp on this but what drives me completely bonkers about this is the Gemini thing was a direct result of people at Google trying to prevent harmful usage of their product whereas the Grok thing is a direct result of people at X and xAI trying to promote harmful usage of their product
Again I find it baffling to compare the coverage to when Gemini generated implausibly many Black hockey players etc. That was apparently a societal emergency. But the mass harassment campaign taking place in public barely warrants a mention.

As ludicrous as this is, keep in mind that NIH F-series fellowships, regardless of the applicant’s age or experience, require undergrad transcripts that will be picked over by a Study Section. A baseless, obnoxious structural barrier to students (like me) with non-traditional career trajectories.
This article advocates for the “Faculty Merit Act” that would — get this — require all faculty applicants to submit their *SAT* scores. 🤣🤣🤣🤣🤣 Holy shirts that’s hilarious.

I do science in clinical and tech-adjacent subfields. Personal style (for women) is often conflated (typically, though not exclusively, by men) with frivolity. Presumed orthogonal to technical skill. Mostly, I don’t care. But I’m on the market now: I have to care, at certain key moments at least.
I’m vowing to focus more on my appearance this year, partially for similar reasons (I’m 43). I slipped into autopilot style-wise during grad school - easy to do in the Gulf South where seasons and layering barely exist - and miss the fun, the discovery, and the sense of honing technique.

I saw a high-reach public health account that I used to consider annoying but innocuous using causal language around LLMs and suicide today, and lost any respect for their capacity for valid inference.
I don't want to fight, so just take this as a personal psych report: it depresses me, and reduces my faith in education, when I see well-respected people with PhDs adduce the heavy-metal-music-suicide hearings as an inspiring precedent for regulation of matrix multiplication.
