The Moral Manager in the Market: How CFOs' Ethical Intelligence Drives ESG Investment in Emerging Economies' Dual Markets

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT What propels a CFO in an emerging economy to champion ESG investments when formal regulations are weak? Moving beyond structural explanations, we provide a behavioural account arguing that a manager's internal ethical compass—moral intelligence (MI)—is a key driver.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Turbulence characterisation for Astronomical Observatories [PDF]

open access: yes, 2012
Atmospheric turbulence has two effects in astronomy; (i) the broadening of the point spread function due to phase fluctuations limiting the resolution of imaging and (ii) producing intensity fluctuations known as scintillation.

Effect of Magnetic Islands on Neoclassical Heat Diffusivity in a Global Tokamak Simulation

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Resonant magnetic perturbations (RMPs) alter magnetic field topology via island formation and can modify core transport in toroidal fusion devices. Using the global gyrokinetic particle‐in‐cell code XGC‐S, originally developed for stellarator geometries, we quantify how island topology affects neoclassical heat transport in a circular tokamak ...

von Kármán self-preservation hypothesis for magnetohydrodynamic turbulence and its consequences for universality [PDF]

open access: yes, 2012
We argue that the hypothesis of preservation of shape of dimensionless second- and third-order correlations during decay of incompressible homogeneous magnetohydrodynamic (MHD) turbulence requires, in general, at least two independent similarity length ...

A contemporary simple risk score for prediction of severe acute kidney injury after heart transplantation

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1166-1175, April 2025.
A contemporary simple risk score for prediction of severe AKI after HT. Abstract Background The aim of this study was to develop a simple risk score to estimate severe acute kidney injury (AKI) risk based on a large contemporary heart transplantation (HT) cohort.

When Does Top Management Team Diversity Matter in Large Organizations?

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

Percolation transition in the kinematics of nonlinear resonance broadening in Charney–Hasegawa–Mima model of Rossby wave turbulence [PDF]

open access: yes, 2013
We study the kinematics of nonlinear resonance broadening of interacting Rossby waves as modelled by the Charney-Hasegawa-Mima equation on a biperiodic domain. We focus on the set of wave modes which can interact quasi-resonantly at a particular level of
