Do Risk Committee Attributes Enhance Climate Risk Disclosure? Evidence From the Listed Mining Firms in South Africa

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the role of risk committee (RC) attributes in climate risk disclosure among 31 mining firms in South Africa. Focusing on annual data between 2016 and 2021, this study employs a feasible generalized least squares technique, a generalized method of moments, and a method of moment quantile regression to control for endogeneity,

Bahaman patch reefs: Numerous and neglected

open access: yesThe Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

Ethanol evaporation drives ester assembly and particle deposition in droplets of Chinese distilled liquors

open access: yesDroplet, EarlyView.
The time‐lapse evaporation of 1.0 µL droplets of strong‐flavor Baijiu (upper panel) and sauce‐flavor Baijiu (lower panel) is observed using a dark‐field phase annulus upright microscope. During evaporation, a noticeable phenomenon of particle assembly occurs, and as these particles move and deposit, they finally exhibit distinct Baijiu‐specific coffee ...

Origin and Interpretation of Low Methamphetamine Levels Found in Amphetamine‐Positive Urine Samples: Support for Methylation of Amphetamine as a Minor Metabolic Pathway

open access: yesDrug Testing and Analysis, EarlyView.
A low urinary concentration of methamphetamine less than 1% of the amphetamine level may not necessarily indicate polydrug use. Instead, it could result from N‐methylation of amphetamine. Chiral analysis of both amphetamines is an effective method for distinguishing between illicit use and therapeutic sources in positive drug screening results ...

Data‐driven analysis of the spatial dependence of grouting efficiency during tunnel excavation

open access: yesDeep Underground Science and Engineering, EarlyView.
Prediction of grouting efficiency using machine learning is enhanced by adopting a training strategy that accounts for the grouting process across multiple rounds. Abstract Grouting with water–cement mixtures is the most widely used and cost‐effective method for managing excess water inflow during tunnel construction.
