Ant Diversity of the Xisha Islands: Community Structure, Exotic Species Colonization, and Ecological Functions in a Tropical Coral Archipelago

open access: yesBiological Diversity, EarlyView.
The first inventory of ants from the Xisha Islands of the South China Sea was compiled, revealing 21 species: 70% native and 30% exotic. Anthropogenic disturbance primarily drove exotic colonization, whereas island area showed weak positive effects on species richness. Most ants were omnivorous, with key mutualistic and seed‐dispersal roles.

From Centrality to Sustainability: How Connected Boards Shape Waste Management Outcomes

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The escalating climate crisis has elevated waste management from an operational concern to a critical issue of corporate governance. However, the role of board connectedness in shaping firms' waste practices remains largely unexplored. Drawing on resource dependency and social capital theories, this study examines how board network centrality ...

GIScience Theory Based Assessment of Spatial Disparity of Geodetic Control Points Location

open access: yesISPRS International Journal of Geo-Information, 2020
Geodetic networks provide a spatial reference framework for the positioning of any geographical feature in a common and consistent way. An even spatial distribution of geodetic control points assures good quality for subordinate surveys in mapping ...

Climate Change, Strategic Orientation, and Green Innovation: Unpacking External and Internal Drivers in Competitive Contexts

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Firms increasingly face political and societal pressures to pursue green strategies and sustainable innovation amid escalating climate change disruptions. Drawing upon contingency theory, institutional theory, and the natural resource‐based view, this article examines external (stakeholder pressures) and internal (environmental culture ...

Measurements on the Absolute 2-D and 3-D Localization Accuracy of TerraSAR-X

open access: yesRemote Sensing, 2018
The German TerraSAR-X radar satellites TSX-1 and TDX-1 are well-regarded for their unprecedented geolocation accuracy. However, to access their full potential, Synthetic Aperture Radar (SAR)-based location measurements have to be carefully corrected for ...

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

open access: yesChemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

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

open access: yesCorporate 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

Fluid‐induced slip on a rate‐and‐state fault during co‐ and post‐injection: The interplay of fluid pressure diffusion and poroelastic stress

open access: yesDeep Underground Science and Engineering, EarlyView.
Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...

Geodetic accuracies obtainable from measurements of first and second order gravitational gradients [PDF]

open access: yes, 1976
The accuracy of an airborne accelerometer-gradiometer system is studied for geodetic applications. A detailed analysis of interpolation, downward continuation and mean value determination is given using the method of least-squares collocation.
