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

Symbolic Versus Substantive ESG Practices: A Systematic Review and Integrative Framework
ABSTRACT ESG reporting is widespread, but symbolic commitments do not always reflect substantive practices. This study conducts a systematic literature review of 62 empirical articles published between 2021 and 2025 to synthesize the main determinants and consequences of this disclosure–performance misalignment in ESG reporting (commonly referred to as

Orchestrating Green Transformation: How AI Adoption Enables Corporate Carbon Neutrality
ABSTRACT As carbon neutrality has become a central goal of global climate governance, how firms achieve low‐carbon transformation has emerged as a critical research issue. However, prior studies have primarily focused on macro‐ or industry‐level analyses, offering limited and fragmented insights into how digital technologies—particularly AI—affect firm‐
