Engineering habits of mind in preschool children at Scottish forest nurseries and Australian bush kinders

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Nature‐based learning environments for early childhood are expanding, as is research into their affordances and pedagogies. Engineering in these environments is not well studied. Previous work considered engineering experiences through the lens of ‘designerly play’, finding that natural materials, the space for larger creations and ...

On the mean subtree order of trees under edge contraction

open access: yesJournal of Graph Theory, Volume 102, Issue 3, Page 535-551, March 2023., 2023
Abstract For a tree T $T$, the mean subtree order of T $T$ is the average order of a subtree of T $T$. In 1984, Jamison conjectured that the mean subtree order of T $T$ decreases by at least 1/3 after contracting an edge in T $T$. In this article we prove this conjecture in the special case that the contracted edge is a pendant edge.

Unruptured brain arteriovenous malformations causing seizures localize to one common brain network

open access: yesJournal of Neuroscience Research, Volume 101, Issue 2, Page 245-255, February 2023., 2023
Seizures are a frequent symptom of unruptured brain arteriovenous malformations (bAVMs). Using VLSM and LNM analyses, we indicated that unruptured bAVMs causing seizures, while anatomically heterogeneous, were located within a common network, which could be a plausible neuroimaging biomarker for the prediction of possible seizures.
