Low‐Carbon Energy Transition and Corporate Carbon Emissions: The Critical Role of Climate Change Mitigation Policies and Institutional Context

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the strategic efficacy of corporate low‐carbon energy transition, such as through nuclear energy adoption, as a response to decarbonization pressures. Analyzing an international sample of energy firms, we demonstrate that the relationship between this form of transition and emission reductions is not technologically ...

Tracking Climate and Environmental Attention: A News‐Based Composite Index

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study introduces the Climate and Environmental Attention Index, a composite indicator that tracks media attention to climate and environmental issues. Based on the Semantic Brand Score, the proposed index extracts significant signals from unstructured text, going beyond traditional measures of word frequency and sentiment.

Modeling and experimental validation of bolt–grout bond–slip behavior for deep underground excavation support

Deep Underground Science and Engineering, EarlyView.
A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such
