King type modification of $q$-Bernstein-Schurer operators [PDF]
, 2013 summary:Very recently the $q$-Bernstein-Schurer operators which reproduce only constant function were introduced and studied by C. V. Muraru (2011). Inspired by J. P. King, Positive linear operators which preserve $x^{2}$ (2003), in this paper we modify $

A-Statistical Convergence Properties of Kantorovich Type λ-Bernstein Operators Via (p, q)-Calculus
Mathematics, 2020 In the present paper, Kantorovich type λ -Bernstein operators via (p, q)-calculus are constructed, and the first and second moments and central moments of these operators are estimated in order to achieve our main results.

Bernstein-Durrmeyer type operators [PDF]
, 1981 RésuméWe study here a new kind of modified Bernstein polynomial operators on L1(0, 1) introduced by J. L. Durrmeyer in [4]. We define for f integrable on [0, 1] the modified Bernstein polynomial Mn f: Mnf(x) = (n + 1) ∑nk = oPnk(x)∝10 Pnk(t) f(t) dt.

Pointwise simultaneous approximation by combinations of Bernstein operators [PDF]
, 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.

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.

A Bézier variant of ( λ , μ ) $(\lambda ,\mu )$ -Bernstein-Kantorovich-Stancu operators
Journal of Inequalities and ApplicationsThis 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.

Business Strategy and the Environment, EarlyView.ABSTRACT Although firms that integrate a sustainability orientation (SO) may experience a significant improvement in their resource efficiency, many, particularly small‐ and medium‐sized enterprises (SMEs), still struggle with the complexities of incorporating sustainability into their business models.

Approximation by $q$-Bernstein type operators [PDF]
, 2011 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 ...

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.
