Essay cheating at universities an 'open secret' despite new law An essay mill owner says he's made millions, while an ex-lecturer says he quit due to rife cheating.

Some students cheat on essays using AI or by paying someone to write for them. But the answer isnโ€™t โ€œsevere penaltiesโ€, itโ€™s to redesign assessments so itโ€™s harder to cheat.

Too many lecturers set essays that are easy to cheat on and then moan that students cheat.

Screenshot of title page including the following abstract:

To minimise confounding bias and disentangle warranted from unwarranted disparities, researchers examining sentencing discrimination have traditionally sought to control for as many legal factors as possible. However, over the past decade, a growing number of scholars have questioned this strategy, noting that many legal factors are themselves subject to judicial discretion and that controlling for them can introduce post-treatment bias. Here, we use directed acyclic graphs (DAGs) to provide a formal and comprehensive assessment of the different types of bias that may arise from different choices of controls. In addition, we propose a new modelling framework to facilitate the selection of controls and reflect the model uncertainty created by the trade-off inherent in judicially-defined legal factors and other factors with a similar dual causal role. We apply this framework to examine race disparities in US federal courts and gender disparities in the England and Wales magistratesโ€™ court. We find substantial model uncertainty for gender disparities and for race disparities affecting Hispanic offenders, rendering estimates of the latter inconclusive. Disparities against black offenders are more consistent and โ€” under specific conditions โ€” could be interpreted as evidence of direct discrimination.

Thrilled to share my latest paper entitled, "Estimating Discrimination in Sentencing: Distinguishing between Good and Bad Controls"

Led by @jpinasanchez.bsky.social, the paper introduces a framework for examining discrimination in criminal justice processes.

When creating PDFs, avoid using "Print to PDF." A screen reader user may still be able to access the text of PDFs created this way, but heading structure, alternative text, and any other tag structure will be lost. Using "Save As" or "Export" can preserve these tags.

The 'bad boyfriend' meme with a man looking at a pretty woman passing by on the street, while his girlfriend looks on in disgust. The man is marked 'random guy at a conference', the pretty woman is marked 'making a comment' and the girlfriend is marked 'asking a question'.

A reminder to my colleagues attending #EuroCrim2025: **a question is a single sentence that ends with a question mark**.

When invited to ask a question in a session, that is not an invitation to give your own talk on an unrelated topic.
