Do CSR Efforts Reduce Environmental Decoupling: Evidence From S&P 500 Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates the impact of Corporate Social Responsibility (CSR) committees and CSR‐focused employee training on environmental decoupling. Using panel data of 2489 firm‐year observations from S&P 500 firms between 2009 and 2022, we employ fixed‐effects models to examine how CSR governance mechanisms influence the alignment between ...

Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

The genetic architecture of epilepsy across molecular mechanisms and clinical heterogeneity

open access: yesEpilepsia Open, EarlyView.
Abstract Epilepsy comprises a highly heterogeneous group of neurological disorders unified by a persistent predisposition to recurrent seizures, yet driven by remarkably diverse genetic, molecular, and network‐level mechanisms. Advances in genomic technologies have revealed that epilepsy arises from a multilayered genetic architecture encompassing rare

NEW SELENIUM-CONTAINING SILVER AMALGAM [PDF]

open access: yes, 1982
An investigation was made to determine the effects of the addition of selenium to the silver-tin amalgam alloy. The addition of 0.2 wt% to 0.6 wt% selenium in the alloy completely eliminated the cytotoxicity, evaluated by the 51Cr release assay and ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

open access: yesGeological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

open access: yesGeological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the
