Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

What Drives CSR Performance: Structures, Declarations or Values?

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability and corporate social responsibility (CSR) are increasingly central to strategic management, yet a gap persists between formal commitments and actual practice. The study explores the structural and value‐based predictors of the institutional integration of CSR and sustainability, with a focus on the mediating role of the CSR ...

Does Internal Corporate Social Responsibility Drive Employee Well‐Being? Evidence From a Positive Balance Perspective

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The significance of fostering an internal corporate social responsibility (ICSR) plan to advance employee well‐being is not fully understood. This article explores employee well‐being from a positive balance perspective, combining the strategic approach to Internal Corporate Social Responsibility with the Theory of subjective well‐being ...

Dynamic Active Site Mechanism and Compositional Tuning in LaxSr1−xCoyFe1−yO3 (LSCF) Perovskites Toward Efficient Oxygen Evolution

EcoEnergy, EarlyView.
A dynamic active site mechanism through cooperative metal–lattice oxygen interactions enables efficient oxygen evolution in LSCF perovskites without relying on oxygen vacancy formation, where the La/Sr ratio governs the intrinsic activity of LSCF and Co incorporation provides secondary enhancement, establishing a general composition‐guided paradigm for
