The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Assessing Angiogenic Properties In Vitro or In Ovo of Pre‐Crosslinked Alginate‐Dialdehyde‐Gelatin Hydrogels Incorporating Boron‐Doped Mesoporous Bioactive Glass Particles

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study examines the influence of boron‐doped mesoporous bioactive glass nanoparticles (MBGN) blended in cast and 3D‐printed pre‐crosslinked alginate‐dialdehyde‐gelatin (ADA‐GEL). Addition of 0.5% and 1% MBGN did not negatively affect the viability of human umbilical vein endothelial cells (HUVECs), or the sprouting of HUVEC spheroids.

Ringspannungs‐vermittelte Aktivierung von Pyridinen durch einen gesättigten BSi2‐Ring

open access: yesAngewandte Chemie, EarlyView.
Wir berichten über ein stark gespanntes Boratadisiliran mit dem bisher nicht zugänglichen anionischen BSi2‐Ringmotiv. Die Spaltung der S–Si‐Bindung während der Reaktionen mit Pyridinderivate aktiviert diese auf drei verschiedene Arten: (1) Bei Pyridin selbst erfolgt eine selektive ortho‐CH‐Aktivierung und ein gleichzeitiger Wasserstofftransfer zu einem

Ring Strain‐Promoted Activation of Pyridines by a Saturated BSi2 Cycle

open access: yesAngewandte Chemie International Edition, EarlyView.
We report a highly strained boratadisilirane with the elusive anionic BSi2 ring motif. Cleavage of the Si─Si bond during reactions with pyridine derivatives activates them in three different ways: 1) for pyridine itself selective ortho‐CH activation and concomitant hydrogen transfer to a second pyridine molecule occurs, 2) with dimethylaminopyridine ...
