When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

What Do We Know About Scope 3 Emissions in Small‐ and Medium‐Sized Enterprises? Mapping Current Knowledge and Advancing a Theory–Practice‐Oriented Framework

Business Strategy and the Environment, EarlyView.
ABSTRACT Although SMEs comprise over 90% of firms globally, research on their engagement with Scope 3 (value‐chain) greenhouse gas emissions remains limited. This PRISMA‐guided systematic review synthesises 49 SME‐relevant studies to develop a theory‐informed, practice‐oriented framework for more credible and sustained Scope 3 engagement.

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Numerical Simulation Analysis of NPR Anchorage Monitoring of Bedding Rock Landslide in Open-Pit Mine

Advances in Civil Engineering, 2020
Nanfen open-pit iron mine is the largest single open-pit mine in Asia. Because of the lag of the extension project, the section has slowly spread in the shape of “V,” and disasters such as landslides occur frequently. In this study, first, the NPR anchor

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

Deep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type
