On the Convergence of a Family of Chlodowsky Type Bernstein-Stancu-Schurer Operators

Journal of Function Spaces, 2018
We construct a new family of univariate Chlodowsky type Bernstein-Stancu-Schurer operators and bivariate tensor product form. We obtain the estimates of moments and central moments of these operators, obtain weighted approximation theorem, establish ...

Quantitative estimates for bivariate Stancu operators

Mathematical Methods in the Applied Sciences, 2018
In this paper, we introduce Voronovskaja‐type and Grüss–Voronovskaja‐ type theorems in quantitative mean with the help of the usual modulus of continuity for bivariate Stancu operators, which are different from a tensor product setting.

Environmental Disclosure Under Mandatory Regulation in EU Listed Companies: An Institutional Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines corporate environmental reporting practices among listed companies in the European Union during the period 2018–2022, within the context of the Non‐Financial Reporting Directive (NFRD). To this end, an Environmental Disclosure Index (EDI) is constructed based on qualitative reporting items, and panel‐data models are ...

Bivariate Maximum Product–Type Favard–Szasz–Mirakyan and Meyer–König–Zeller Operators

Journal of Mathematics
In the present paper, we set up the structure of the bivariate maximum product (max-product)–type of Meyer–König and Zeller operators and Favard–Szasz–Mirakyan operators corresponding to the linear univariate counterparts.

From Capabilities to Competitive Greening: Managerial Commitment and Green Shared Vision as Serial Mediators in Energy‐Sector SMEs

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on dynamic capabilities view and upper echelons theory, this study shows how energy‐sector SMEs convert dynamic capabilities into green competitive advantage. We theorize that sensing–seizing–reconfiguring routines are associated with green competitive advantage only when top managers visibly prioritize environmental goals and foster a

Co-operational bivariant theory

Mathematics Research Reports
For a covariant functor W. Fulton and R. MacPherson defined an operational bivariant theory associated to this covariant functor. In this paper we will show that given a contravariant functor one can similarly construct a “dual” version of an operational bivariant theory, which we call a

Greening the Bottom Line: Public Funding for Circular Economy Initiatives and Financial Stability

Business Strategy and the Environment, EarlyView.
ABSTRACT Public funding for circular economy (CE) initiatives plays a crucial role in shaping corporate financial performance, yet its effects remain underexplored. Grounded in the resource‐based view (RBV) of the firm, this study investigates the financial impact of CE funding on private firms, using Portugal as a case study. It analyses the financial

A Study on Affine Invariance in ψ-Modified Szász-Kantorovich Operators

Journal of Mathematics
In this paper, we propose and analyze a modified class of -ψ Szász–Mirakjan–Kantorovich operators that preserve affine functions. The proposed modified-ψ Szász–Mirakjan–Kantorovich operators exhibit superior approximation properties compared to both the ...

The Fast, the Steady and the Tenacious: Funding Pathways for Circular Start‐Ups

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular start‐ups (CSUs) are critical for unlocking the circular economy, yet they face persistent barriers in accessing finance. Despite growing interest from policymakers and financing institutions, little empirical evidence explains how these ventures pursue and secure funding.
