Observability properties of the homogeneous wave equation on a closed manifold [PDF]
Communications in Partial Differential Equations, 2016 We consider the wave equation on a closed Riemannian manifold. We observe the restriction of the solutions to a measurable subset ω along a time interval with T> 0.

British Educational Research Journal, EarlyView.Abstract This study examined teachers' perspectives on how children benefit from time in nature, how disadvantage shapes access and the role of schools in facilitating such access. Drawing on interviews conducted in 2022 with 25 UK primary school teachers who participated in Generation Wild, a nature connection programme for schools in economically ...

Null controllability of a model in population dynamics
Electronic Journal of Differential Equations, 2014 In this article, we study the null controllability of a linear model with degenerate diffusion in population dynamics. We develop first a Carleman type inequality for the adjoint system of an intermediate model, and then an observability inequality.

On Weak Observability for Evolution Systems with Skew-Adjoint Generators [PDF]
SIAM Journal on Mathematical Analysis, 2018 In the paper we consider the linear inverse problem that consists in recovering the initial state in a first order evolution equation generated by a skew-adjoint operator.

British Educational Research Journal, EarlyView.Abstract Drawing upon interview research across two academic departments as part of the early stages of a ‘decolonise the curriculum’ initiative at a Southern UK university, this study highlights a growing gulf between policy and practice in efforts to address systemic racial inequalities in UK universities. A reliance upon precarious labour, a culture

Electronic Journal of Differential Equations, 2019 We study a reachability problem for a second-order integro-differential equation on a finite-dimensional Riemannian manifold, which is a model equation for viscoelasiticity.

, 2017 This paper studies connections among observable sets, the observability inequality, the H lder-type interpolation inequality and the spectral inequality for the heat equation in $\mathbb R^n$. We present a characteristic of observable sets for the heat equation.

Contrasting roles of school and public libraries in lower primary pupils' reading
British Educational Research Journal, EarlyView.Abstract Libraries represent an important institutional component of children's reading socialisation, yet their role is often treated as uniform despite substantial differences between school and public libraries. This study examines how visits to school and public libraries relate to pupils' reading attitudes, practices and self‐assessed reading ...

Taxation, redistribution, and observability in social dilemmas
Journal of Public Economic Theory, 2019 In the presence of social dilemmas, cooperation is more difficult to achieve when populations are heterogeneous because of conflicting interests within groups.

British Educational Research Journal, EarlyView.Abstract This paper analyses differences in academic achievement associated with attendance at publicly funded private schools and public schools across 11 European countries. Using eight waves of PISA data (2000–2022), we apply OLS, IPW and IPWRA estimators to account for observed heterogeneity and mitigate selection bias.
