Supramolecular Polymerization and Morphological Transformation of Dynamic Helical Poly(Phenylacetylene)s via Chain‐End Host–Guest Interactions

open access: yesAngewandte Chemie, EarlyView.
A helical polymer whose chain ends are connected through pillar[5]arene‐based host–guest interactions translates molecular helicity into supramolecular morphology. Solvent‐triggered helicity inversion accompanied by changes in chain rigidity switches the supramolecular architecture between cyclic and rigid‐rod nanostructures.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Diagnosing the system: Mental health, necropolitical uncare, and the abolition of migration detention

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This article examines the psychological effects of migration detention in the European Union's Closed Controlled Access Center (CCAC) on Samos through an ecological lens. It explores a double normalization of suffering: the brutalization of necropolitical migration governance and the simultaneous understanding of resulting distress as an ...

How Are Australian Local Governments Responding to the Homelessness Crisis? Findings From a National Study

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Australian local governments are facing intensifying pressures to respond to worsening visible homelessness. This paper presents one of the first national studies on how local governments are responding to these pressures, and the first since the onset of the post‐pandemic housing crisis.
