The Curriculum Journal, EarlyView.Abstract Education, including school education, is widely understood as fundamental to a just response to global climate and ecological crises. We examined the practices of teachers based in England focused on climate change and sustainability education (CCSE).

Energy Science & Engineering, 2021 In a numerical analysis of a Stirling engine, the thermal and flow fields in the cylinder are three‐dimensional and periodically varying. Therefore, a computational fluid dynamic (CFD) analysis may provide detailed solution but it takes a long ...

Asymptotics of Stirling and Chebyshev‐Stirling Numbers of the Second Kind
Studies in Applied Mathematics, 2014 For the classical Stirling numbers of the second kind, asymptotic formulae are derived in terms of a local central limit theorem. The underlying probabilistic approach also applies to the Chebyshev–Stirling numbers, a special case of the Jacobi–Stirling numbers.

Becoming inclusive: Developing pre‐service teachers' orientations towards their practice in Scotland
The Curriculum Journal, EarlyView.Abstract This article presents findings, from a case study with a cohort of third‐year undergraduate pre‐service teachers (PSTs) in Scotland, regarding their ideas about inclusion and curricular justice, as they concurrently encountered practice and theory.

Computing generating functions of ordered partitions with the transfer-matrix method [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 An ordered partition of $[n]:=\{1,2,\ldots, n\}$ is a sequence of disjoint and nonempty subsets, called blocks, whose union is $[n]$. The aim of this paper is to compute some generating functions of ordered partitions by the transfer-matrix method.

Divisibility by 2 and 3 of certain Stirling numbers
, 2008 The numbers e_p(k,n) defined as min(nu_p(S(k,j)j!): j >= n) appear frequently in algebraic topology. Here S(k,j) is the Stirling number of the second kind, and nu_p(-) the exponent of p. The author and Sun proved that if L is sufficiently large, then e_p(

The Group of Generalized Stirling Numbers
Advances in Applied Mathematics, 2001 An algebraic approach to the generalized Stirling numbers is presented, leading to a unified interpretation for important combinatorial functions such as the binomials, Stirling numbers, and Gaussian polynomials. Let \(G\) be the group of all infinite lower triangular matrices \(A\) over a field \(K\) of characteristic \(0\) for which \(A(n,m)= 1 ...

Curricular justice in a complex world
The Curriculum Journal, EarlyView.Abstract This paper is a response to articles published in this Special Issue of the journal. In the paper, I reflect upon the issue of curricular justice, offering comment on issues raised in the constituent papers of the Special Issue. The arguments are structured around four themes: education IS political; the questions of whose knowledge should be ...

Ecography, EarlyView.Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

On a Recurrence involving Stirling Numbers
European Journal of Combinatorics, 1984 Let \(Z(n)=\sum^{n-1}_{k=1}S(n,k) Z(k)\), where S(n,k) denotes the Stirling numbers of the second kind. The author proves the asymptotic order of magnitude of Z(n), i.e. \(c_ 1\leq Z(n)/f(n)\leq c_ 2\) where \(c_ 1\), \(c_ 2\) are positive constants, and \(f(n)=(n!)^ 2(n \log 2)^{-n} n^{-1-(\log 2)/3}.\)
