Towards Responsible Mining in Africa: Problematising the Environmental and Public Health Concerns of Artisanal and Small‐Scale Gold Mining in Ghana

Sustainable Development, EarlyView.
ABSTRACT There have been emerging media reports on the impact of cyanide and mercury use in artisanal and small‐scale gold mining (ASGM) operations on community health, especially among pregnant and non‐pregnant women, ASGM miners, and children in rural Africa.

Women own differently: How women's decision‐making authority shapes owner teams' strategic choices in private firms

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary The literature on the strategic role of ownership in creating firm value suggests that owners' ultimate decision‐making authority allows them to align their firms' strategic orientations with their idiosyncratic judgment. By integrating the strategic ownership literature with social role theory, we theorize how women owners ...

Balancing allocative and dynamic efficiency with redundant R&D allocation: The role of organizational proximity and centralization

Strategic Management Journal, EarlyView.
Abstract Research Summary Resource‐based‐view scholars have mainly examined two resource allocation approaches for competitive advantage in multiunit firms: resource sharing and resource redeployment. These approaches emphasize allocative efficiency—the optimal allocation of resources to maximize their current value. In technology‐intensive industries,

Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality

Small, EarlyView.
2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key
