Observability inequality and decay rate for wave equations with nonlinear boundary conditions
Electronic Journal of Differential Equations, 2017 We study a class of wave propagation problems concerning the nonlinearity of dynamic evolution for boundary material. We establish an observability inequality for the related linear system, and make a connection between the linear system and the ...

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.

British Educational Research Journal, EarlyView.Abstract The mental health and wellbeing of young people has received increasing attention in both research and the wider public discourse. There has been a marked rise in mental health conditions in young people, and the burden of care is increasingly transferred onto schools and teachers.

Partial exact controllability for the linear thermo-viscoelastic model
Electronic Journal of Differential Equations, 1998 The problem of partial exact controllability for linear thermo-viscoelasticity is considered. Using classical multiplier techniques, a boundary observability inequality is established under smallness restrictions on coupling parameters and relaxation ...

British Educational Research Journal, EarlyView.Abstract School Attendance Problems (SAPs) represent a significant challenge requiring early identification and intervention. Current service provision often does not recognise early indicators that parents observe, creating gaps between when initial concerns are raised and formal support is provided.

Breaking point: Identifying the factors that predict suspension from school
British Educational Research Journal, EarlyView.Abstract School suspensions are associated with adverse educational and psychosocial outcomes, yet little is known about how structural disadvantage, relational factors, health behaviours, well‐being indicators and school‐level factors jointly predict suspension risk in England.

Null controllability of population dynamics with interior degeneracy
Electronic Journal of Differential Equations, 2017 In this article, we study the null controllability of population model with an interior degenerate diffusion. To this end, we proved first a new Carleman estimate for the full adjoint system and then we deduce a suitable observability inequality which

Observation of Bell inequality violation in B mesons [PDF]
Journal of Modern Optics, 2004 A pair of $B^0\bar B^0$ mesons from $Υ(4S)$ decay exhibit EPR type non-local particle-antiparticle (flavor) correlation. It is possible to write down Bell Inequality (in the CHSH form: $S\le2$) to test the non-locality assumption of EPR. Using semileptonic $B^0$ decays of $Υ(4S)$ at Belle experiment, a clear violation of Bell Inequality in particle ...

Complex Firms, Controversial Outcomes: Global Evidence on ESG Failures and Remedies
Business Strategy and the Environment, EarlyView.ABSTRACT We examine whether business complexity increases firms' exposure to negative environmental, social, and governance (ESG) outcomes, specifically ESG controversies, using a global panel of firms from 37 countries over the period 2002–2021.
