What You Say Predicts How You Do: A Multilevel Analysis of Corporate Environmental Performance

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the relationship between firms' declarations about environmental issues and actual environmental performance improvement across a set of key environmental performance indicators. Multilevel regression analysis was conducted using a unique data set comprising 7449 firms from 22 industries headquartered in 86 countries for ...

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

open access: yesDeep 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 ...
