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

open access: yesConsumer 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.

Utilizing robustness of positive buck-boost converter against input voltage and load current disturbances

open access: yes, 2009
A Positive Buck- Boost (PBB) converter is a known DC-DC converter that can operate in step up and step down modes. Unlike Buck, Boost, and Inverting Buck Boost converters, the inductor current of a PBB can be controlled independently of its voltage ...

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

open access: yesBritish 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

open access: yesBritish 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 ...

Socioeconomic status, parenting factors and academic achievement among Chinese adolescents aged 12–13: How do they relate?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Extensive research has shown that students from higher socioeconomic status (SES) backgrounds generally outperform their lower SES peers. Nevertheless, some low SES students succeed, albeit it ‘against the odds.’ Coleman's (1988) theory of social capital in the family suggests that financial capital, human capital and social capital all affect
