CSR Sustainability Reporting and Enterprise Value: The Moderating Role of Regulatory Quality in the European Policy Landscape

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The study looks into the relationship between the extent of CSR Sustainability Reporting and Enterprise Value (EV) among European listed companies. The introduction of the Corporate Sustainability Reporting Directive (CSRD) 2022/2464/EU and the European Sustainability Reporting Standards (ESRS) has significantly heightened the demand for ...

High‐Order Projection‐Based Upwind Method for Simulation of Transitional Turbulent Flows

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
In this study, we evaluated the implicit large‐eddy simulation capabilities of the mass‐conserving mixed stress method for transitional turbulent flows and proposed an efficient solution method for large‐scale applications. The results presented in this work show promising outcomes for incompressible aerodynamic flow problems, which can be further ...

Exact Values and Bounds on Covering Schemes of Strength Two

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT In this work, we investigate covering schemes of strength 2 over finite abelian groups, establishing new lower and upper bounds and evaluating new exact values. A main result is a new general lower bound that improves the trivial one and achieves optimality for the binary case. We also develop a recursive relation based on subsets of the group

Partial Steiner Triple Systems With an Almost Parallel Class Missing Any Given Point

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT We say that a hypergraph is factor critical if it has no 1‐factor but deletion of any vertex results in a hypergraph that has a 1‐factor. We show that any factor‐critical hypergraph of order n $n$ has at least n $n$ edges, and that for all integers k > 1 $k\gt 1$ and n > 1 $n\gt 1$ with n ≡ 1 ( mod k ) $n\equiv 1({\rm{mod}}\,k)$ there exists a

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...
