International Journal of Finance &Economics, EarlyView.ABSTRACT This paper examines the impact of regulatory controls on Bitcoin's excess returns and volatility. The paper innovates by proxying changes in the regulatory environment using global Google search volume intensity data. The generated regulatory indices accurately identify episodes of regulatory tightening within cryptocurrency markets.

Numerical computation of shock wave-turbulent boundary layer interaction in transonic flow over an axisymmetric curved hill [PDF]
A control-volume based finite difference computation of a turbulent transonic flow over an axisymmetric curved hill is presented. The numerical method is based on the SIMPLE algorithm, and hence the conservation of mass equation is replaced by a pressure

From Reactive to Proactive Volatility Modeling With Hemisphere Neural Networks
Journal of Applied Econometrics, EarlyView.ABSTRACT We revisit maximum likelihood estimation (MLE) for macroeconomic density forecasting through a novel neural network architecture with dedicated mean and variance hemispheres. Our architecture features several key ingredients making MLE work in this context.

Computation of supersonic jet mixing noise for an axisymmetric CD nozzle using k-epsilon turbulence model [PDF]
The turbulent mixing noise of a supersonic jet is calculated for a round convergent-divergent nozzle at the design pressure ratio. Aerodynamic computations are performed using the PARC code with a k-epsilon turbulence model.

Journal of Corporate Accounting &Finance, EarlyView.ABSTRACT This study investigates how Corporate Digital Transformation (CDT) influences audit opinions in Chinese A‐share‐listed non‐financial firms from 2011 to 2022, with a focus on the moderating role of Economic Policy Uncertainty (EPU). Results reveal an inverted U‐shaped relationship: moderate levels of CDT enhance audit outcomes through improved ...

From Empire to Aid: Analysing Persistence of Colonial Legacies in Foreign Aid to Africa
Journal of International Development, EarlyView.ABSTRACT For decades now, Western development agencies and donors have been castigated for their colonial biases in providing aid to Africa. It is well established that donors provide considerably more foreign aid to their former colonies relative to other countries.

A near-wall four-equation turbulence model for compressible boundary layers [PDF]
A near-wall four-equation turbulence model is developed for the calculation of high-speed compressible turbulent boundary layers. The four equations used are the k-epsilon equations and the theta(exp 2)-epsilon(sub theta) equations.

When Does Top Management Team Diversity Matter in Large Organizations?
Journal 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 ...
