Sailing From Penalties to Accountability: Business Strategies and Governance for Firms to Innovate After Environmental Misconduct

Business Strategy and the Environment, EarlyView.
ABSTRACT Firms' continuous pursuit of making a profit in the competitive market may ignore the actions related to environmental responsibilities. This set of actions for financial gains constitutes environmental misconduct, which not only harms ecosystems and communities but also brings reputational damage. Negative press and social media amplification

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

Deep Underground Science and Engineering, EarlyView.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...
