Blending type approximation by GBS $GBS$ operators of bivariate tensor product of λ-Bernstein–Kantorovich type

Journal of Inequalities and Applications, 2018
In this paper, we introduce a family of GBS $GBS$ operators of bivariate tensor product of λ-Bernstein–Kantorovich type. We estimate the rate of convergence of such operators for B-continuous and B-differentiable functions by using the mixed modulus of ...

Digital Orientation and Green Practices in Chilean SMEs: Innovation as the Pathway to Competitive Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how digital strategic orientation (DSO) and environmental practices (EP) interact to shape innovation and performance among Chilean SMEs. Using survey data from 271 firms (February–May 2022), we estimate a generalized structured component analysis (GSCA) model that accommodates a nonrecursive relationship between DSO and EP.

The Second Ditzian-Totik modulus revisited: refined estimates for positive linear operators

Journal of Numerical Analysis and Approximation Theory, 2003
Direct theorems for approximation by positive linear operators in terms of the second order Ditzian-Totik modulus of smoothness are proved. Special emphasis is on the magnitude of the absolute constants.

On a quasi-interpolating Bernstein operator

Journal of Approximation Theory, 2015
A special case of the modification of Lagrange interpolation due to Bernstein is considered as follows: \[ B_{n}(f,x) := B_{n,1}(f,x) = \sum_{i=1}^{[n/2]} \, f(x_{2i-1}) \{ l_{2i-1}(x)+l_{2i}(x) \} + (n-2[n/2]) f(x_{n}) l_{n}(x), \] where \(x_{i} := x_{in} = \cos t_{i},\) \(t_{i} := \frac{2i-1}{2n} \pi,\) \(i = 1,2,\ldots, n\) are the roots of the ...

Carbon Footprint of Bank Loans: Opportunities and Risk Implications in the Banking Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether the carbon footprint of bank loan portfolios influences bank stability, profitability and cost efficiency and whether regulatory quality moderates these relationships. Using a balanced panel of 33 countries from 2005 to 2018, the analysis combines banking‐sector indicators from the World Bank Global Financial ...

Navigating Ethical Minefields: Micro‐Foundations of Corporate Political Work in Ethical and Sustainable Business Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT In an era of rising geopolitical tensions and environmental instability, corporate political activities have become increasingly intertwined with ethical challenges and sustainability requirements. This study investigates the influence of environmental dynamics and corporate ethical responsibility on interorganizational conflict and ...

Some identities of degenerate Euler polynomials associated with degenerate Bernstein polynomials

Journal of Inequalities and Applications, 2019
In this paper, we investigate some properties and identities for degenerate Euler polynomials in connection with degenerate Bernstein polynomials by means of fermionic p-adic integrals on Zp $\mathbb{Z}_{p}$ and generating functions.

Prosumers and Sustainable Market Governance: Development of the Community‐Oriented Marketing Approach Scale

Business Strategy and the Environment, EarlyView.
ABSTRACT This research develops and empirically validates the Community‐Oriented Marketing Approach (COMA), a 20‐item multidimensional scale designed to measure prosumer perceptions within participatory market systems. COMA conceptualizes prosumers as active co‐value creators and institutional agents, driving sustainable market governance.

Climate Risk and Real Estate Markets in the EU: Institutional Control Through Regulation

Business Strategy and the Environment, EarlyView.
ABSTRACT Climate change is increasingly reshaping the economic foundations of asset markets, yet its implications for the estate sector remain unevenly understood, particularly when institutional and financial mechanisms mediate risk transmission. While a growing body of evidence links climate vulnerability to property valuation and market behaviour ...

Iterates of a modified Bernstein type operator

Journal of Numerical Analysis and Approximation Theory, 2019
Using the weakly Picard operators technique and the contraction principle, we study the convergence of the iterates of some modified Bernstein type operators.
