Disaggregating ESG Practices and Performance Outcomes: Empirical Evidence From the European Healthcare Industry

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the associations between Environmental, Social, and Governance (ESG) practices and organizational performance in 283 European hospitals. Drawing on agency theory, stakeholder theory, and the resource‐based view, it analyses ESG indicators as accounting‐relevant information within the institutional context of European ...

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

Approximation by $q$-Bernstein type operators [PDF]

open access: yes, 2009
summary:Using the $q$-Bernstein basis, we construct a new sequence $\{ L_{n} \}$ of positive linear operators in $C[0,1].$ We study its approximation properties and the rate of convergence in terms of modulus of ...

Improved Conservative Scheme for Lenard‐Bernstein Collisions in Gyrokinetic Turbulence Simulations

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Turbulence in the edge and scrape‐off layer regions plays a critical role for the performance of future magnetic confinement fusion power plants. Gyrokinetic simulations allow studying this regime with high fidelity. A key aspect in these regions is the high concentration of impurities, which can radiate energy, leading to significant losses ...

A Kantorovich Version of Bernstein‐Type Logarithmic Operators

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we introduce a Kantorovich version of the Bernstein‐type logarithmic operators. The idea comes from the wide literature concerning exponential polynomials that preserve exponential functions: here, the exponential weights are replaced by logarithmic ones and the corresponding operators preserve the logarithmic functions.

Markov‐Associated Quadratic Stochastic Families and the Susceptible‐Infected‐Recovered (SIR) Model

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We introduce a Markov‐associated construction for quadratic stochastic families generated by a symmetric cubic stochastic matrix and a finite‐state homogeneous Markov semigroup. The constructed family is not assumed to be a classical quadratic stochastic process of type (A)$$ (A) $$ or type (B)$$ (B) $$; rather, it is a Markov‐associated ...

Measuring Institutional Work in Sustainability Reporting: Scale Development and Validation in the Oil and Gas Sector

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainability reporting has gained significant importance in assessing and enhancing organisational sustainability performance. However, there has been limited focus on how sustainability reporting managers (SRMs) perceive and engage in the institutional work that underpins reporting practices.

Calibrating Bayesian inference

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Bayesian statistics has gained popularity in psychological research due to its intuitive uncertainty quantification and convenient information‐updating rules. In many applications, however, prior distributions are introduced merely as instruments to facilitate computation, rather than as representations of genuine subjective belief ...

Pointwise simultaneous approximation by combinations of Bernstein operators

open access: yes, 2005
We prove in the present paper some new direct and inverse results on pointwise simultaneous approximation by combinations of Bernstein operators by using ωϕλ2r(f,t), where ωϕλ2r(f,t) is the Ditzian–Totik modulus of smoothness.

Statistical Approximation of q-Bernstein-Schurer-Stancu-Kantorovich Operators [PDF]

open access: yes, 2014
We introduce two kinds of Kantorovich-type q-Bernstein-Schurer-Stancu operators. We first estimate moments of q-Bernstein-Schurer-Stancu-Kantorovich operators. We also establish the statistical approximation properties of these operators. Furthermore, we
