Supply Chain Network, ESG Scores and Financial Performance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper provides novel evidence on the role of supply chain networks in influencing firms' environmental, social and governance (ESG) scores and financial performance. Our analysis employs financial, board, ESG and supply chain data, resulting in an unbalanced panel of over 16,000 firm‐year observations from 3028 publicly traded US firms ...

New approach to finding eigenvectors for repeated eigenvalues of a matrix

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï
An efficient method of calculating eigenvectors for multiple eigenvalues of a matrix is proposed. This method is based on a formalized transformation of the problem of solving degenerate systems of equations into a regular problem by “repairing” their ...

How Supply Chain Transparency Shapes the Impact of Green Credit on Corporate Digital Responsibility

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Drawing on panel data from 4229 firm‐year observations of Chinese A‐share listed companies (2011–2022), this study investigates the relationship between green credit and corporate digital responsibility (CDR), focusing on the mediating role of supply chain transparency (SCT).

Robust Regularized Locality Preserving Indexing for Fiedler Vector Estimation

open access: yesIEEE Open Journal of Signal Processing
The Fiedler vector is the eigenvector associated with the algebraic connectivity of the graph Laplacian. It is central to graph analysis as it provides substantial information to learn the latent structure of a graph. In real-world applications, however,

Eigenvectors of Perturbed Operators

open access: yesJournal of Mathematical Analysis and Applications, 1999
The main result of this article constitutes the following theorem: Let \(A:H\rightarrow H\) be a compact selfadjoint operator and \(f\) a strictly increasing differentiable function in the interval \(I.\) For \(z\in H\) form a family of compact selfadjoint operators \(A(t)=A+f(t)\langle\cdot,z \rangle z\).

An eigenvector condition for reconstructibility

open access: yesJournal of Combinatorial Theory, Series B, 1982
AbstractThe following theorem is proved: If there exists a subgraph Gj of G none of whose eigenvectors is orthogonal to C, where C is the vector with each component equal to one, then G is reconstructible.

A partial envelope approach for modelling multivariate spatial‐temporal data

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.

Multivariate Identification via Linear Projection of Eigenvectors

open access: yesMathematics
A data-driven system identification algorithm that utilizes eigenvectors is presented. The eigenvectors are extracted from a unified solution space comprising both input and output subspaces. To expand the input subspace, a higher-order subspace from the
