Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

Advanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

Beyond a Technocentric Transition: A Diverse Economies Perspective for Social Justice in Circular Economy Business Models

Business Strategy and the Environment, EarlyView.
ABSTRACT The circular economy, dominated by capitalocentric, technocentric, and eco‐modernist discourses, risks perpetuating systemic injustice because of its limited consideration of the social and of what is possible. In this article, we examine how social justice can be embedded into circular business models (CBMs)—key drivers of the circular ...
