Bottled Water and the Social Sciences: A Review and Agenda for Future Research
Sociology Compass, Volume 20, Issue 3, March 2026.ABSTRACT Social sciences approach the steady rise of bottled water consumption at the beginning of the 21st century from four analytical vantage points: political economy, semiotics and lifestyle, political ecology, and materiality‐centered. Each analytic has crucial methodological and conceptual contributions to make, as well as zones of potential ...

A new type of q-Szász-Mirakjan operators [PDF]
, 2017 In this paper we introduce a new q-Sz?sz-Mirakjan operator based on a new q-exponential function. We derive various formulae for the moments, prove the uniform convergence of the sequence of operators to the identity operator on compact ...

“The Way They Speak of Masters and Johnson”: The Rise and Disappearance of Sex Therapy, 1960–2000
Journal of the History of the Behavioral Sciences, Volume 62, Issue 2, Spring 2026.ABSTRACT A keyword search of “sex therapy” in the New York Times shows a rapid rise for articles covering the discipline in the 1970s, an equally rapid reduction in the 1980s, and further decline in the 1990s and into the 2000s. This surprising inflection, given that sex as a marketable construction did not decline in the late 20th century, opens room ...

Bernstein-Durrmeyer operators [PDF]
, 1995 In this paper, we consider the Durrmeyer-type modifications of the classical Bernstein, Szász and Baskakov operators, and deal with two different kind of problems.

Dunkl generalization of Phillips operators and approximation in weighted spaces
Advances in Difference Equations, 2020 The purpose of this article is to introduce a modification of Phillips operators on the interval [ 1 2 , ∞ ) $[ \frac{1}{2},\infty ) $ via a Dunkl generalization. We further define the Stancu type generalization of these operators as S n , υ ∗ ( f ; x ) =

Asymptotic Properties for a General Class of Szász–Mirakjan–Durrmeyer Operators
Mathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 734-743, 30 January 2026.ABSTRACT In this paper, we introduce a general family of Szász–Mirakjan–Durrmeyer type operators depending on an integer parameter j∈ℤ$$ j\in \mathbb{Z} $$. They can be viewed as a generalization of the Szász–Mirakjan–Durrmeyer operators, Phillips operators, and corresponding Kantorovich modifications of higher order.

Symmetric Properties of λ-Szász Operators Coupled with Generalized Beta Functions and Approximation Theory [PDF]
This research work focuses on λ-Szász–Mirakjan operators coupling generalized beta function. The kernel functions used in λ-Szász operators often possess even or odd symmetry.

On the Rates of Approximation of Bernstein Type Operators [PDF]
, 2001 Asymptotic behavior of two Bernstein-type operators is studied in this paper. In the first case, the rate of convergence of a Bernstein operator for a bounded function f is studied at points x where f(x+) and f(x−) exist.

On the Reducibility of Weighted Composition Operators Generated by Periodic Transformations
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.In this article, we study the reducibility of weighted composition operators (also known as weighted displacement operators) acting on Banach spaces of continuous functions on a compact topological space X. We consider operators of the form Bu(x) = a(x)u(α(x)), where α : X⟶X is a continuous mapping and a is a continuous function.
