Impacts of Migration as Adaptation: Assessing Translocal Social Resilience in Eastern, Northern and Greater Accra Regions, Ghana

open access: yesPopulation, Space and Place, Volume 32, Issue 5, July 2026.
ABSTRACT Migration is increasingly recognised as an adaptive strategy to enhance social resilience amid environmental and socioeconomic stressors. However, systematic assessments of its impact on both migrants and their households remain limited. This study applies the translocal social resilience framework to analyse migration outcomes across origin ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Augmented Harris Hawks Optimizer with Gradient-Based-Like Optimization: Inverse Design of All-Dielectric Meta-Gratings

open access: yesBiomimetics, 2023
In this paper, we introduce a new hybrid optimization method for the inverse design of metasurfaces, which combines the original Harris hawks optimizer (HHO) with a gradient-based optimization method.

A local projection stabilised HHO method for the Oseen problem

open access: yesComputers & Mathematics with Applications
In this article, we consider a local projection stabilisation for a Hybrid High-Order (HHO) approximation of the Oseen problem. We prove an existence-uniqueness result under a stronger SUPG-like norm. We improve the stability and provide error estimation in stronger norm for convection dominated Oseen problem.
