King type modification of $q$-Bernstein-Schurer operators [PDF]

open access: yes, 2011
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 $

Some Approximation Results For (p, q)-Lupas-Schurer Operators

open access: yes, 2018
In this paper, we introduce Lupas-Schurer operators based on (p, q)-integers. Then, we deal with the approximation properties for (p, q)-Lupas-Schurer operators based on Korovkin type approximation theorem.

A Note on Approximation of Blending Type Bernstein–Schurer–Kantorovich Operators with Shape Parameter α

open access: yesJournal of Mathematics, 2023
The objective of this paper is to construct univariate and bivariate blending type α-Schurer–Kantorovich operators depending on two parameters α∈0,1 and ρ>0 to approximate a class of measurable functions on 0,1+q,q>0.

Some approximation results on Chlodowsky type q−Bernstein-Schurer operators

open access: yes, 2023
The main concern of this article is to obtain several approximation features of the new Chlodowsky type q-Bernstein-Schurer operators. We prove the Korovkin type approximation theorem and discuss the order of convergence with regard to the ordinary ...

Bivariate Bernstein–Schurer–Stancu type GBS operators in ( p , q ) $(p,q)$ -analogue

open access: yesAdvances in Difference Equations, 2020
The purpose of this paper is to construct a ( p , q ) $(p,q)$ -analogue of Bernstein–Schurer–Stancu type GBS (generalized Boolean sum) operators for approximating B-continuous and B-differentiable functions.

Approximation by bivariate generalized Bernstein–Schurer operators and associated GBS operators

open access: yesAdvances in Difference Equations, 2020
We construct the bivariate form of Bernstein–Schurer operators based on parameter α. We establish the Voronovskaja-type theorem and give an estimate of the order of approximation with the help of Peetre’s K-functional of our newly defined operators ...

Whether and when: Women's work, birth spacing, and parity progression in late‐nineteenth‐century Derbyshire

open access: yesThe Economic History Review, EarlyView.
Abstract Women's labour force participation features prominently in discussions of low birth rates and the Second Demographic Transition, and has also been hypothesized to have played a role in falling marital fertility during the First Demographic Transition.

A Tale of Two Cities: Australian Evidence on the Effects of Lockdown on Grocery Inflation

open access: yesOxford Bulletin of Economics and Statistics, Volume 88, Issue 6, Page 1455-1465, December 2026.
ABSTRACTDespite extensive research on the economic implications of COVID‐19, the inflationary consequences of lockdown remain underexplored. Prior impact assessments may be compromised due to the cross‐jurisdictional presence of lockdowns and the prevalence of the coronavirus. This study leverages a unique circumstance in Australia, where Melbourne was

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

open access: yesAmerican Journal of Political Science, Volume 70, Issue 4, Page 1464-1481, October 2026.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of
