A discrete spectral method for time fractional fourth-order 2D diffusion-wave equation involving ψ-Caputo fractional derivative

open access: yesResults in Applied Mathematics
In this work, the ψ-Caputo fractional derivative, as a generalization of the classical Caputo fractional derivative in which the fractional derivative of a sufficiently differentiable function is defined with respect to another strictly increasing ...

Incomplete Caputo fractional derivative operators

open access: yesAdvances in Difference Equations, 2018
The main aim of this paper is to give the definitions of Caputo fractional derivative operators and show their use in the special function theory. For this purpose, we introduce new types of incomplete hypergeometric functions and obtain their integral ...

On the chaotic nature of the Rabinovich system through Caputo and Atangana–Baleanu–Caputo fractional derivatives

open access: yesAdvances in Continuous and Discrete Models, 2022
AbstractThe Rabinovich system can describe different physical interactions, including waves in plasmas, a convective fluid flow inside a rotating ellipsoid, and Kolmogorov’s flow interactions. This study considers the Rabinovich system through Caputo and Atangana–Baleanu fractional derivatives to detect its chaotic nature.

Ethical Behaviour and Corporate Financing. The Case of ‘Legality Rating’

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The financial crisis has heightened awareness of ethical and legal issues in the business context. Corporate ethical behaviour is increasingly measured through sustainability ratings. Since 2012, in Italy, the introduction of a sustainability rating, namely the legality rating (LR), has served as an innovative ‘label’ for socially responsible ...

Board Independence and Corporate Social Responsibility: A Literature Review With a Focus on Country Effects

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the relationship between board independence and corporate social responsibility (CSR) outcomes. Based on legitimacy theory, we conducted a structured literature review of 167 archival studies to analyze the influence of board independence on CSR performance and reporting.

Approximations for the Caputo Derivative (I)

open access: yes, 2016
In this paper we construct approximations for the Caputo derivative of order $1-α,2-α,2$ and $3-α$. The approximations have weights $0.5\left((k+1)^{-α}-(k-1)^{-α}\right)/Γ(1-α)$ and $k^{-1-α}/Γ(-α)$, and the higher accuracy is achieved by modifying the initial and last weights using the expansion formulas for the left and right endpoints.

When Sustainability Reporting Becomes a Strategy: The Impact of Financial Performance and Institutional Pressures From EU Sustainability Reporting Regulations on ESG Decoupling

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Mitigating environmental, social, and governance (ESG) decoupling is essential to advancing reliable sustainability disclosure and ensuring that ESG reporting fulfills its intended purpose. This study aims to provide critical insights into the organizational and contextual elements that could intensify or diminish ESG decoupling. Using a multi‐
