On Certain Best Constants for Bernstein-Type Operators

Journal of Approximation Theory, 2001
In the paper \textit{Z. Li} [J. Approximation Theory 102, 171-174 (2000; Zbl 0957.41017)] the best constant problem was introduced. In the present paper the authors study a generalized version of this problem. Also, some best constants for well-known Bernstein-type operators are calculated. The results are too technical to be reproduced in detail here.

Growth of Omnichannel Grocery Retailing and Food Prices

Agribusiness, EarlyView.
ABSTRACT This paper examines the effects of the growth of omnichannel grocery retailing on food prices. We first develop a conceptual model of consumer choice and retailer pricing that allows us to evaluate changes in equilibrium prices, quantities, and profits with online channel growth and alternative pricing strategies.

Approximation by Complex Perturbed Bernstein-Type Operators

Results in Mathematics, 2020
The authors introduce the complex form of the perturbed Bernstein operators attached to analytic functions \(f:D_R\to\mathbb{C}\), where \(D_R=\{z\in\mathbb{C}\, \vert\, \vert z \vert < 1 \}\) and \(R>1\). Quantitative estimates of the convergence in compact disks and the exact degree of simultaneous approximation are established.

Consumer Acceptance of New Sustainable Food Technologies: Upcycling Technology, Biostimulants, and Artificial Intelligence

Agribusiness, EarlyView.
ABSTRACT Food systems have a significant impact on environmental sustainability, underscoring the need for innovative technologies to support more sustainable agricultural methods. However, the adoption of these technologies hinges on consumer acceptance, making the analysis of consumer perceptions essential.

Chlodowsky variant of Bernstein-type operators on the domain

Open Mathematics
In the present paper, we deal with Bernstein-Chlodowsky type operators for approximating functions on the domain. We first present Bernstein-Chlodowsky type operators in two variables and then we discuss some examples of these operators under a domain ...

‘Let's talk about the weather’: The activist curriculum and global climate change education

British Educational Research Journal, EarlyView.
Abstract Activist movements have garnered significant global attention on a range of sustainability issues, often involving collectives of citizens coming together. Invoked is the idea of citizens informed to act, emerging not from a common‐sense understanding of everyday life, but rather from a deep political understanding of the world—one that is ...

A Bézier variant of ( λ , μ ) $(\lambda ,\mu )$ -Bernstein-Kantorovich-Stancu operators

Journal of Inequalities and Applications
This paper mainly introduces ( λ , μ ) $(\lambda ,\mu )$ -Bernstein-Kantorovich-Stancu-Bézier operators that are a natural continuation of Stancu-type ( λ , μ ) $(\lambda ,\mu )$ -Bernstein-Kantorovich operators constructed by Q.-B. Cai et al.

Activism as a long durée journey: Teachers against the Chilean neoliberal education model

British Educational Research Journal, EarlyView.
Abstract In this paper, I use the idea of purposes of education, particularly subjectification, and the concept of love to explore long‐term teacher activism in Chile. ‘Long‐term activism’ is used to describe an ongoing struggle rather than activism confined to specific moments.

Phillips-Type q-Bernstein Operators on Triangles

Journal of Function Spaces, 2021
The purpose of the paper is to introduce a new analogue of Phillips-type Bernstein operators Bm,qufu,v and Bn,qvfu,v, their products Pmn,qfu,v and Qnm,qfu,v, their Boolean sums Smn,qfu,v and Tnm,qfu,v on triangle Th, which interpolate a given function on
