A new hybrid orthonormal Bernstein and improved block-pulse functions method for solving mathematical physics and engineering problems

Alexandria Engineering Journal, 2020
In this paper, numerical solution of the linear second kind Fredholm integral equations is studied. These integral equations are widely used for solving many problems in mathematical physics and engineering.

The Bernstein Function: A Unifying Framework of Nonconvex Penalization in Sparse Estimation [PDF]

, 2013
In this paper we study nonconvex penalization using Bernstein functions. Since the Bernstein function is concave and nonsmooth at the origin, it can induce a class of nonconvex functions for high-dimensional sparse estimation problems.

Moment problems related to Bernstein functions [PDF]

Annales de la Faculté des sciences de Toulouse : Mathématiques, 2020
We give a simple proof of the moment-indeterminacy on the half-line of the sequence (n!) t for t>2, using Lin’s condition. Under a logarithmic self-decomposability assumption, the method conveys to power moment sequences defined as the rising factorials of a given Bernstein function, and to more general infinitely divisible moment sequences.

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.

Bernstein-type approximation using the beta-binomial distribution

Statistica, 2013
The Bernstein-type approximation using the beta-binomial distribution is proposed and studied. Both univariate and multivariate Bernstein-type approximations are studied. The uniform convergence and the degree of approximation are studied.

Civilising pedagogies: An ethnography of instructional and regulative discourses in government schools in Delhi, India

British Educational Research Journal, EarlyView.
Abstract Over the years, surveys and data on learning outcomes have consistently shown inadequate levels of learning in schools in India, witnessing a further decline in recent years. Studies within the sociology of education have consistently highlighted the overarching role of class and caste on learning outcomes in schools. Neoliberal policy reforms

Some Identities on the 𝑞-Integral Representation of the Product of Several 𝑞-Bernstein-Type Polynomials

Abstract and Applied Analysis, 2011
The purpose of this paper is to give some properties of several 𝑞-Bernstein-type polynomials to express the 𝑞-integral on [0, 1] in terms of 𝑞-beta and 𝑞-gamma functions.

Growth mindset is positively associated with mathematics attainment in Scotland—But socioeconomic status plays a greater role

British Educational Research Journal, EarlyView.
Abstract There is currently a gap in knowledge around pupils' growth mindset (GM) and attainment in Scotland, particularly in relation to Socioeconomic Status (SES). This study offers insights on the relevance of growth mindset in Scotland for attainment in mathematics by drawing on large‐scale data from the OECD's Programme for International Student ...

How do secondary schools in England talk about modern languages? A corpus‐assisted discourse analysis of school websites

British Educational Research Journal, EarlyView.
Abstract Situating the study within an ecological perspective on language education, this article examines how secondary schools in England present Modern Languages (MLs) on official school websites. Focusing on 44 schools in Local Authorities with the lowest percentage average entry for the Languages pillar of the EBacc, we built a text database ...

Classifying avian drinking behaviour: ecological insights and implications in a changing world

Biological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns
