A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

A Linearized Porous Media Model Revisited—On Its Derivation via Variationally Consistent Homogenization and Upscaling

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The classical theory of porous media is based on assumed micro‐homogeneity of the solid phase (skeleton). Based on the drained macroscale elastic stiffness, it is possible to analytically compute auxiliary properties such as the Biot‐Willis and Skempton parameters.

Shaping Manager Well‐Being and Functioning in Declining Nonprofit Organizations: The Critical Role of Strategy Implementation

Nonprofit Management and Leadership, EarlyView.
ABSTRACT Under the roof of Christian churches in Central Europe, some nonprofit organizations (NPOs) grow, while others are in marked decline. Our study in this context extends a previous focus on financial indicators to NPO managers' experiences, their role clarity and job satisfaction, during phases of organizational growth and decline. Specifically,

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

People and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Emergent media narratives on land conflicts in a global biocultural diversity hotspot

People and Nature, EarlyView.
Abstract Land conflicts (LCs) represent major challenges in regions where limited resources are contested by diverse actors. The triple frontier of the bioculturally diverse Alto Paraná Atlantic Forests (APAF) ecoregion concentrates some of the most intense LCs in South America.

The Long Trajectory of Rubber Physics: 3500+ Years and Counting

Journal of Polymer Science, EarlyView.
Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...
