GDP and GDI Growth Accounting in the Open Economy: Multiplicative Fisher Decompositions

open access: yesReview of International Economics, EarlyView.
ABSTRACT While most national statistical agencies still use chained Laspeyres indices in their national accounts, the U.S. Bureau of Economic Analysis (BEA) and Statistics Canada have been at the forefront for the past two decades by using instead a superlative index—the Fisher index—when computing price and quantity indices for GDP and its components.

Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

open access: yesExperimental Physiology, EarlyView.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

Brain strain: Blood flow and metabolism in environmental extremes

open access: yesExperimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Is resting muscle sympathetic nerve activity related to peripheral or cerebrovascular haemodynamics at high altitude? A retrospective analysis

open access: yesExperimental Physiology, EarlyView.
Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...
