Renewing the Sydney undergraduate curriculum.

A number of commentators have recently called for a re-examination of the purpose and value of undergraduate education, arguing that change is required if universities are to deliver the value in educational outcomes that students and communities now require for a changing and challenging world (for example, Aoun, 2017; Bok, 2020; Davidson, 2017; Fischman & Gardner, 2022). Indeed, some have argued that such change is necessary to stem an emerging crisis in universities' 'social license to operate' (Bok, 2020). In this paper, we review the case for undergraduate curriculum change and present a case study of one Australian university's engagement with this challenge, describing the reasons for change, the desired outcomes, and some early impacts on students' study patterns.

Hidden Charge Order in an Iron Oxide Square-Lattice Compound.

Since the discovery of charge disproportionation in the FeO_{2} square-lattice compound Sr_{3}Fe_{2}O_{7} by Mössbauer spectroscopy more than fifty years ago, the spatial ordering pattern of the disproportionated charges has remained "hidden" to conventional diffraction probes, despite numerous x-ray and neutron scattering studies. We have used neutron Larmor diffraction and Fe K-edge resonant x-ray scattering to demonstrate checkerboard charge order in the FeO_{2} planes that vanishes at a sharp second-order phase transition upon heating above 332 K. Stacking disorder of the checkerboard pattern due to frustrated interlayer interactions broadens the corresponding superstructure reflections and greatly reduces their amplitude, thus explaining the difficulty of detecting them by conventional probes.

Optimal governance and implementation of vaccination programmes to contain the COVID-19 pandemic.

Since the recent introduction of several viable vaccines for SARS-CoV-2, vaccination uptake has become the key factor that will determine our success in containing the COVID-19 pandemic. We argue that game theory and social network models should be used to guide decisions pertaining to vaccination programmes for the best possible results. In the months following the introduction of vaccines, their availability and the human resources needed to run the vaccination programmes have been scarce in many countries.

The dynamic course of psychological outcomes following the Victorian Black Saturday bushfires.

Objectives: To profile the long-term mental health outcomes of those affected by the 2009 Black Saturday bushfires and to document the course of mental health since the disaster.

Method: The longitudinal Beyond Bushfires study included 1017 respondents (Wave 1; 3-4 years after the fires), 736 (76.1%) at Wave 2 (5 years after the fires) and 525 (51.
