Merging Psychological, Social, and Rational Perspectives: A Study of the Determinants of Consumer Choices for Sustainable Furniture

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines consumer purchase intentions for a sofa produced through industrial symbiosis (IS), utilizing recycled textiles and fibers. As a high‐investment product, the IS sofa requires a significant financial commitment and involves complex decision‐making, an area less studied compared with other sustainable goods categories.

Bivariate Chlodowsky-Stancu Variant of (p,q)-Bernstein-Schurer Operators

open access: yesJournal of Function Spaces, 2019
In this study, it is proposed to define bivariate Chlodowsky variant of (p,q)-Bernstein-Stancu-Schurer operators. Therefore, Korovkin-type approximation theorems and the error of approximation by using full modulus of continuity are presented.

Bernstein–Jacobi-type operators preserving derivatives

open access: yesComputational and Applied Mathematics
AbstractA general frame for Bernstein-type operators that preserve derivatives is given. We introduce Bernstein-type operators based in the weighted classical Jacobi inner product on the interval [0, 1] that extend the well known Bernstein–Durrmeyer operator as well as some other types of Bernstein operators that appear in the literature.

$L^p$-convergence of Bernstein-Kantorovich-type operators [PDF]

open access: yesAnnales Polonici Mathematici, 1996
Summary: We study a Kantorovich-type modification of the operators introduced by the authors [Approximation properties of recursively defined Bernstein-type operators, preprint 1994] and we characterize their convergence in the \(L^p\)-norm. We also furnish a quantitative estimate of the convergence.

Guidelines for Scale Development and Validation

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT Scales, serving as measurement instruments composed of carefully designed items intended to capture latent constructs, play a critical role in advancing consumer theory and marketing practice. Yet, developing and validating scales poses a formidable challenge due to the diverse methods required to ensure rigor and robustness.

Approximation Properties of Generalized λ-Bernstein–Stancu-Type Operators

open access: yesJournal of Mathematics, 2021
The present study introduces generalized λ-Bernstein–Stancu-type operators with shifted knots. A Korovkin-type approximation theorem is given, and the rate of convergence of these types of operators is obtained for Lipschitz-type functions.

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Blending type approximation by generalized Bernstein-Durrmeyer type operators [PDF]

open access: yesMiskolc Mathematical Notes, 2018
In this article we construct a Durrmeyer modification of the operators introduced by Chen et al. in [10] based on a non-negative real parameter. We establish local approximation, global approximation, Voronovskaja type asymptotic theorem. The rate of convergence for differentiable functions whose derivatives are of bounded variation is also obtained.

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Approximation by Kantorovich Type q-Bernstein-Stancu Operators [PDF]

open access: yesComplex Analysis and Operator Theory, 2016
In this paper, we introduce a Kantorovich type generalization of q-Bernstein-Stancu operators. We study the convergence of the introduced operators and also obtain the rate of convergence by these operators in terms of the modulus of continuity. Further, we study local approximation property and Voronovskaja type theorem for the said operators. We show
