Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary Despite the urgent need for a circular economy, firms' transition from linear to circular business models (CBMs) remains slow. While previous research suggests that dynamic capabilities are the key drivers of this transition, it assumes a direct link, overlooking that these capabilities can facilitate change but do not ...

Experimental Physiology, EarlyView.Abstract This study investigated cerebral and neuromuscular responses to three exercise models: time trial (TT), maximal oxygen uptake (V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$) and time to exhaustion (TTE). Fourteen participants completed the tests in the following order: V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$, TT and ...
