Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Dynamic growth estimates of maximum vorticity for 3D incompressible Euler equations and the SQG model [PDF]

open access: yes, 2012
By performing estimates on the integral of the absolute value of vorticity along a local vortex line segment, we establish a relatively sharp dynamic growth estimate of maximum vorticity under some assumptions on the local geometric regularity of the ...

Designing Governance for ESG: Incentive and Oversight Complementarities in Corporate Sustainability Performance

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates how internal governance design supports credible ESG performance by distinguishing between Incentive and Oversight Architectures. Using 13,993 firm‐year observations of US nonfinancial firms from 2018 to 2024, we estimate fixed effects and two‐step system GMM models.

CEO Duality and Corporate Social Responsibility. A Literature Review With a Focus on Country Effects

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT In recent years, many researchers have become interested in the relationship between CEO duality (where one individual serves as both CEO and board chair) and CSR outcomes. Given the varied research results, this structured literature review concentrates on the country effects of this dynamic link.
