Rational QCD loop amplitudes and quantum theories on twistor space

open access: yesJournal of High Energy Physics
We show how curing an anomaly of the twistor uplift of self-dual Yang-Mills theory implies linear relations among one-loop, n-gluon, color-ordered subamplitudes in QCD, when all n gluon helicities are positive, or when exactly one is negative. We compute

VISUAL NEGOTIATIONS OF GENTRIFICATION IN TORONTO: Contestation, Politicization and Resistance through Urban Signage

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract This article engages signage as a medium through which urban stakeholders negotiate the politics of housing redevelopment and gentrification in cities. Focusing on Toronto, we examine housing‐related signage in three neighbourhoods where social mix approaches to redevelopment have ushered in gentrification: Parkdale, Regent Park, and Moss Park.

Can Scope Make a Difference? Assessing the Reach of Due Diligence Laws in Supply Networks

open access: yesGlobal Policy, EarlyView.
ABSTRACT Human rights and environmental due diligence (HREDD) laws seek to make companies legally accountable for adverse social and environmental impacts across their supply chains. Although jurisdictionally bounded, these laws rest on the assumption that their influence can extend globally through supply networks.

Changing public perceptions of alcohol, alcohol harms and alcohol policies: A multi‐methods study to develop novel framing approaches

open access: yesAddiction, Volume 120, Issue 4, Page 655-668, April 2025.
Abstract Background and aims Public perceptions of alcohol and its related harms and policies are shaped by multiple discourses and can influence behaviour and policy support. As part of a FrameWorks‐informed project to test framing approaches to improve public understanding and support for evidence‐based alcohol policies in the UK, this research aimed

‘I'd rather have worse gums than worse lungs’: Young people's views of nicotine pouches in the UK

open access: yesAddiction, EarlyView.
Abstract Background and aims Nicotine pouches entered the UK market in 2019. Although research has shown that young people's prevalence of use has been low, it has been reported to be increasing and a cause for concern. This paper reports the findings of the first qualitative study in the UK to explore the views of 14–16 year olds' knowledge, awareness

A divisibility property for stirling numbers

open access: yesJournal of Number Theory, 1978
AbstractIn this paper we calculate which prime powers ps divide Δn, m = g.c.d.{k! S(n, k)|m ≤ k ≤ n} for s < p. Here S(n, k) is a Stirling number of the second kind.
