Evaluating undergraduate mathematics examinations in the era of generative AI: a curriculum-level case study
Generative artificial intelligence (GenAI) tools such as OpenAI's ChatGPT are transforming the educational landscape, prompting reconsideration of traditional assessment practices. In parallel, universities are exploring alternatives to in-person, closed-book examinations, raising concerns about academic integrity and pedagogical alignment in uninvigilated settings. This study investigates whether traditional closed-book mathematics examinations retain their pedagogical relevance when hypotheti…

On the relationship between prediction intervals, tests of sharp nulls and inference on realized treatment effects in settings with few treated units
We study how inference methods for settings with few treated units that rely on treatment effect homogeneity extend to alternative inferential targets when treatment effects are heterogeneous -- namely, tests of sharp null hypotheses, inference on realized treatment effects, and prediction intervals. We show that inference methods for these alternative targets are deeply interconnected: they are either equivalent or become equivalent under additional assumptions. Our results show that methods d…

The Impact of Automation on Risk-Taking: The Role of Sense of Agency
Automation significantly alters human behavior, particularly risk-taking. Previous researches have paid limited attention to the underlying characteristics of automation and their mechanisms of influence on risk-taking. This study investigated how automation affects risk-taking and examined the role of sense of agency therein. By quantifying sense of agency through subjective ratings, this research explored the impact of automation level and reliability level on risk-taking. The results of thre…

Interesting that some who replied to my post on tax and GDP growth yesterday missed the point.
The point isn't to debate whether tax -> growth (it might, with a tail wind).
The point is that
1) Growth won't happen like it used to.
2) That is good because GDP growth is ecologically and socially lethal.
3) So our leaders (sic) had better adapt to the new reality and use taxation and other measures to build a better, fairer future.

Getting Real about the Crises Facing the UK | Stop the Damage! Build a Better Future!
Britain and the rest of the world face a set of almost intractable challenges, ecological (including climate), economic and social. Yet political leaders with few exceptions are failing to propose the actions and policies that could address the scale of this pancrisis. Here though is an alternative initiative, a kind of alternative manifesto with a portfolio of illustrative policies...

Gesture Evaluation in Virtual Reality
Gestures are central to human communication, enriching interactions through non-verbal expression. Virtual avatars increasingly use AI-generated gestures to enhance life-likeness, yet evaluations have largely been confined to 2D. Virtual Reality (VR) provides an immersive alternative that may affect how gestures are perceived. This paper presents a comparative evaluation of computer-generated gestures in VR and 2D, examining three models from the 2023 GENEA Challenge. Results show that gestures…

“Trump has a child’s understanding of the world and is driven by ego and whatever impulses come into his weak mind. It’s causing the U.S. economy to burn as he pursues trade and economic policies that are completely unworkable and destroys U.S. leadership on the global stage. And he’s doing a lot of it to distract from the Epstein files.”
