Integrability of a Verhulst biological population model via Lie point symmetries

Purpose This study focuses on understanding species population dynamics through a (3 + 1)-dimensional biological population model governed by Verhulst's logistic growth law. The main objective is to explore how nonlinear growth and spatial diffusion mechanisms influence the evolu...

Boundary conditions of the impact of high-performance work systems on flourishing and job performance: an organizational justice perspective

Purpose This study examines the role of employees' perceptions of organizational justice in shaping the effects of high-performance work systems (HPWS) on job performance through employee well-being, operationalized as flourishing. Design/methodology/approach Using a two-source,...

A unified fixed point approach for enriched bivariate mappings with applications to volterra systems and fractional-order chaos

We develop a unified fixed point theory for enriched bivariate contractions in ordered Banach spaces and in ordered convex metric spaces. Two classes of mappings are introduced and analysed: enriched bivariate Ciric-Reich-Rus contractions ( 𝒞 B C R R C e ) and enriched bivariate...

Work ability configurations and conditional HR decision premises: a programme-oriented framework for age management

Purpose Ageing workforces require organisations to decide what to prioritise when older workers' work abilities differ. This article develops the Cyclical Meaning Pattern of Abilities (CMPA) as a programme-oriented human resource (HR) decision heuristic. CMPA conceptualises how c...

Research on Game-Theoretic Behavior of Collective Emergency Evacuation in Wildfire Under the Drive of Individual Risk Perception

The increasing frequency of wildfires has made large-scale collective emergency evacuation increasingly critical. However, existing studies provide limited understanding of how information structures shape the interaction between individual risk perception and collective evacuati...

UAV image segmentation in complex mining areas by integrating spatially adaptive feature modulation and multi-scale context fusion modules

To address the misclassification of visually similar ground objects and inaccurate boundary localization caused by background interference, as well as small-object omission, fragmented regions, and incomplete boundaries resulting from scale variations, this study proposes MASwin-...

Fake leadership and fake news undermining the “want” dimension of organizational recovery

Purpose Organizational dark sides disrupt organizational functioning and may escalate into organizational destruction, creating a need for organizational recovery. They disturb the organizational status quo, constituting organizational change in themselves by introducing new cond...
