Getting (un)wasted: How planning failures generate consumer waste across resources: Time, money, goods, and energy

Consumer Psychology Review, EarlyView.
Abstract Past research suggests that people exhibit robust waste aversion. However, many consumers routinely feel that they waste not only goods but also time, money, energy, and emotion and would be hard‐pressed to imagine their lives otherwise. Why does consumer waste persist? In this paper, we first propose a definition for consumer waste.

Environmental impact of antidepressants: Is a new prescription framework possible?

British Journal of Clinical Pharmacology, EarlyView.
Aims Antidepressants such as venlafaxine and sertraline pose high risks to water ecosystems. As depressive disorders and other mental health conditions become increasingly prevalent worldwide, prescription and environmental presence of these pharmaceuticals continue to rise. This study explores the practical viability of a new framework for prescribing

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

British Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...
