Corporate Social Responsibility and Firm Profitability in South Africa: An Industry‐Level Analysis

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the relationship between corporate social responsibility and profit on assets in South Africa using a panel dataset comprising 79 industries observed annually between 2017 and 2024. The study uses an industry‐level dataset which, unlike firm‐level inquiries, purges firm‐level noise and acknowledges the empirical regularity ...

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

open access: yesDeep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

open access: yesEcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Modulating Growth Kinetics and Defect Passivation in Ambient‐Air Evaporation‐Spray Deposition Enables Efficient and Stable Rigid/Flexible Perovskite Solar Cells

open access: yesEcoEnergy, EarlyView.
ATC‐enabled synergistic crystalline regulation and defect passivation via evaporation‐spray deposition realizes 22.68% rigid and 20.13% flexible PSCs with remarkable stability and excellent universality for both rigid and flexible substrates. ABSTRACT Evaporation‐spray technique renders perovskites highly compatible with large‐scale manufacturing ...
