When most people think of AI in education they probably don't think of scientific journals old enough to exist online as black and white photocopies. Here's a cover from the first volume of the Journal of AI in Education 1989/90. It contains a really signficant paper...

I have also done a lot of writing and commenting this month but still seem to have a stack of papers to be worked on and submitted 😲

Guess who hates university collegiality? Apparently collegiality is inconsistent with 'modern people management'. So it fucking should be. The university is not there to serve its own HR department.

NeurIPS reviewers typically review 6+ papers, each with 100 or so citations. The reviewers can't possibly check that every citation is real. But why don't we have an automated way to do this checking (and desk-rejecting if fake citations found) *before* the papers are sent to reviewers?

Key Points
Question
Does acetaminophen use during pregnancy increase children's risk of neurodevelopmental disorders?
Findings
In this population-based study, models without sibling controls identified marginally increased risks of autism and attention-deficit/hyperactivity disorder (ADHD) associated with acetaminophen use during pregnancy.
However, analyses of matched full sibling pairs found no evidence of increased risk of autism (hazard ratio, 0.98), ADHD (hazard ratio, 0.98), or intellectual disability (hazard ratio, 1.01) associated with acetaminophen use.
Meaning
Acetaminophen use during pregnancy was not associated with children's risk of autism, ADHD, or intellectual disability in sibling control analyses. This suggests that associations observed in other models may have been attributable to confounding.
Abstract
Importance
Several studies suggest that acetaminophen (paracetamol) use during pregnancy may increase risk of neurodevelopmental disorders in children. If true, this would have substantial implications for management of pain and fever during pregnancy.
Objective
To examine the associations of acetaminophen use during pregnancy with children's risk of autism, attention-deficit/hyperactivity disorder (ADHD), and intellectual disability.

Design, Setting, and Participants
This nationwide cohort study with sibling control analysis included a population-based sample of 2,480,797 children born in 1995 to 2019 in Sweden, with follow-up through December 31, 2021.
Exposure
Use of acetaminophen during pregnancy prospectively recorded from antenatal and prescription records.
Main Outcomes and Measures
Autism, ADHD, and intellectual disability based on International Classification of Diseases, Ninth Revision and International Classification of Diseases, Tenth Revision codes in health registers.
Results
In total, 185909 children (7.49%) were exposed to acetaminophen during pregnancy. Crude absolute risks at 10 years of age for those not exposed vs those exposed to acetaminophen were 1.33% vs 1.53% for autism, 2.46% vs 2.87% for ADHD, and 0.70% vs 0.82% for intellectual disability. In models without sibling control, ever-use vs no use of acetaminophen during pregnancy was associated with marginally increased risk of autism (hazard ratio [HR], 1.05 [95% CI, 1.02-1.08]; risk difference [RD] at 10 years of age, 0.09% [95% Cl,
-0.01% to 0.20%l), ADHD (HR, 1.07 [95% Cl, 1.05-1.10];
RD, 0.21% [95% Cl, 0.08%-0.34%]), and intellectual disability (HR, 1.05 [95% CI, 1.00-1.10]; RD, 0.04% [95% Cl, -0.04% to 0.12%]).
To address unobserved confounding, matched full sibling pairs were also analyzed. Sibling control analyses found no evidence that acetaminophen use during pregnancy was associated with autism (HR, 0.98 [95% Cl, 0.93-1.04]; RD, 0.02% [95% Cl, -0.14% to 0.18%l), ADHD (HR, 0.98 [95% Cl, 0.94-1.02]; RD, -0.02% [95% Cl, -0.21% to 0.15%]), or intellectual disability (HR, 1.01 195% Cl, 0.92-1.10]; RD, 0% [95% Cl, -0.10% to 0.13%1).

In short, acetaminophen exposure during pregnancy is not linked to the risk of developing autism, ADHD, or intellectual disability.

The study has been published in Journal of the American Medical Association (JAMA). YES, it is PEER-REVIEWED.

WELL NOW, would you look at that?

A massive, 26-YEAR-LONG study of MORE THAN 2.4 MILLION people in Sweden found found NO EVIDENCE to support a causal link between acetaminophen (the API in Tylenol) use during pregnancy and increased risk of autism, ADHD, OR intellectual disability in children.

I'm sorry. As a technology writer, I'm supposed to be telling you that this bet will some day pay off, because one day we will have shoveled so many words into the word-guessing program that it wakes up and learns how to actually do the jobs it is failing spectacularly at today. This is a proposition akin to the idea that if we keep breeding horses to run faster and faster, one of them will give birth to a locomotive. Humans possess intelligence, and machines do not. The difference between a human and a word-guessing program isn't how many words the human knows.

I'm sorry. I know that when we talk about "digital sovereignty," we're obliged to talk about how we can build more data-centres that we can fill up with money-losing chips from American silicon monopolists in the hopes of destroying as many jobs as possible while blowing through our clean energy goals and enshittifying as much of our potable water as possible.

This reverses 4 years of progress in providing greater certainty & ability to plan for researchers, their families & unis.

How's that even going to work with the 2x DP cap, given +1 yr on responses? Seems as well thought through as a paper raincoat.

ECR/MCR precarity is already ridiculous, but this is only going to make it worse. Genuinely have to wonder if it'd be easier for the ARC if we all just left research.

Let’s not let our analysis stop at the goonerism of it all. I’m begging for our view of this to be wider than some guy’s stained pants.

It’s a labour weapon. A missile to bomb us out of public life. One email to a boss and a woman loses her job, her income, and her independence. That’s the point.

Getting grok to publicly strip a woman’s likeness online or alter her image isn’t just horrifying at the level of the individual, it’ll be used to get us fired, too.

"And I never say no"

We need to have a serious talk about the way "AI companion" apps not only prey on the vulnerable, but are priming their users to ignore consent and to conflate love with control.

We need AI regulations across so many sectors, but this area is particularly horrifying.

Text reads: About synthetic panels
Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels.

Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey.

Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away.

Question-writing best practices
To get the most reliable and actionable results from synthetic audiences, consider these question-writing best practices:

Ask forward-looking and attitudinal questions.
Synthetic panels perform best with perceptions, preferences, and intent-based questions. For example, β€œHow likely are you to try…?”
Synthetic panels are less applicable for studies on past behaviors, detailed recall, brand recall, or awareness questions. For example, β€œWhen did you last visit…?”

Discussion
The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002)
of the variance in behaviour to be explained by intention and PBC.
