Green Developmentalism? The Political Economy of Hydropower in India in the 21st Century
Development and Change, EarlyView.ABSTRACT This article critically examines the political economy of hydropower in India since its global reconfiguration as ‘green energy’ in the early 2000s. While an opportune convergence of interests among key global, national and subnational stakeholders contributed to the greening of hydropower in India, this reframing did not produce the expected ...

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 ...
