Triple bottom line determinants of inter‐organizational collaboration in the Spanish social economy

Annals of Public and Cooperative Economics, EarlyView.
Abstract This study examines determinants of inter‐organizational collaboration in social economy organizations through a triple bottom line framework. Using data from 2002 Spanish organizations participating in REAS social balance sheet (2019–2024), we employ generalized linear mixed models to analyse how economic, social and environmental factors ...

A Semirefining Extrapolation Multigrid Method With Fourth-Order Compact Schemes for 2D Nonlinear Elliptic Equations

Journal of Mathematics
A novel semirefining extrapolation nonlinear multigrid (SENMG) method is proposed for computing high-accuracy numerical solutions of two-dimensional (2D) nonlinear elliptic equations discretized by fourth-order compact finite difference schemes.

A balance between stability and flexibility: Adaptive patterns of self‐regulated learning processes shape game‐based learning

British Journal of Educational Technology, EarlyView.
Abstract To ensure learning efficiency in game‐based learning (GBL), learners must regulate cognitive, affective, metacognitive and motivational (CAMM) processes, collectively known as self‐regulated learning (SRL). SRL is dynamic and non‐linear, characterized by regulatory patterns and CAMM interactions that lead to macro‐level SRL behaviours. In this

Differentiable Randers‐Finsler Eikonal Solvers

Computer Graphics Forum, EarlyView.
Abstract Fast and differentiable solvers for anisotropic and asymmetric distance fields are a key primitive in geometry processing, enabling gradient‐based optimization over metrics, drift fields, and downstream objectives that depend on geodesic distances and geodesics.

Evaluating a double integral using Euler\u27s method and Richardson extrapolation [PDF]

, 2023
We transform a double integral into a second-order initial value problem, which we solve using Euler\u27s method and Richardson extrapolation. For an example we consider, we achieve accuracy close to machine precision (1e-15).
