Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

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.

Optimum hovering wing planform [PDF]

open access: yes, 2016
Theoretical analysis is used to identify the optimum wing planform of a flapping/revolving wing in hover. This solution is of interest as a benchmark to which hovering wing geometries driven by broader multidisciplinary evolutionary or engineering ...

SpartanAnatomy.org: Evaluating a new interactive neuroradiology tool for early medical education

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Teaching neuroanatomy through the lens of magnetic resonance imaging (MRI) offers medical students a strong foundation for success. However, many existing MRI learning resources lack interactivity and user‐friendliness, require payment, or include an overwhelming number of labeled structures.

Bricks, knots, and bodies: Material encounters and the affective making of masculinity

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper examines how creative research methods do not just capture boys' experiences of masculinity, but actively materialise them. Drawing on two arts‐based activities used in school‐based fieldwork (a mannequin‐based exercise with one participant and a Lego‐building workshop with a small peer group), the paper analyses how materials ...

Dynamic Spillovers Between FinTech, Blockchain, and Green Finance: A Quantile Connectedness Approach

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper explores how financial innovation and environmental sustainability intersect by analyzing spillovers between FinTech, blockchain energy use, and green finance. Using a Quantile Vector Autoregression (QVAR) framework, we examine weekly data from 2018 to 2024 across 11 digital, environmental, and macro‐financial indices.
