National and Subnational Models of Care That Support Primary Health Care: A Mixed‐Methods Study

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT In 2020, the World Health Assembly called on countries to reorient their models of care (MOCs) toward primary health care (PHC). This study's objectives were to (a) describe common use of the concept of MOC; and (b) identify implemented MOCs and their components that support PHC at national and subnational levels. A scoping review charted data

Direct Numerical Simulation of Magnetohydrodynamic Slip‐Flow Past a Stretching Surface Using Physics‐Informed Neural Network

Heat Transfer, EarlyView.
ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Sustainability Performance and Corporate Risk: Evidence From the Tourism Industry

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of sustainability performance (Refinitiv Environmental, Social, and Governance [ESG] scores) on corporate risk (CR). We apply stakeholder theory and the resource‐based view to an international sample of 247 tourism firms from 2002 to 2018.

Interplay Between Green Investment and Market Price Premia in Global Shipping

International Journal of Finance &Economics, EarlyView.
ABSTRACT Existing research emphasises that the driver of green investment is its future profitability. This paper shows that other investors' decisions also influence green investment. We take the example of scrubber installation in shipping, which is optional by regulation but has an established market for trading its underlying asset.
