Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

Adapting to Water Scarcity in Mediterranean Greenhouse Agriculture: Insights From Digital Irrigation and Regulated Water Governance in Southeastern Spain

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Climate‐driven water scarcity is compounding adaptation pressures on Mediterranean greenhouse farming, particularly for small and micro agricultural firms governed by regulated water‐governance systems. This paper analyses differentiated adaptation profiles in Almería (Spain) based on an analysis of farm structure, digital irrigation adoption,

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

Corporate 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 ...

Climate Vulnerability and Sovereign ESG Performance: The Conditioning Roles of Adaptation Innovation, Institutional Quality and Robot Adoption

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The intensification of physical climate risk presents a critical question for global sustainability governance: does exposure to climate hazards strengthen or weaken a country's environmental, social and governance (ESG) performance? This study investigates the relationship between climate vulnerability and country‐level ESG performance across
