Abstract: Accurate school‐level enrolment predictions are critical for local government and planners to allocate education‐related resources and ensure necessary school infrastructure is provided. Although in idual‐level school census data are increasingly available for education departments, there is little evidence that these data are being used to improve school enrolment projections. This paper fills this methodological void by developing a School Transition Estimation and Projection (STEP) modelling framework. The STEP model simultaneously projects all schools in a city or region by all academic levels (e.g., Preschool to Year 12) and across three school sectors (Public, Catholic and Independent) using cohort information on the sources of enrolment change (i.e., Preschool entries, within district transfers, in‐migration, out‐migration, Year 12 graduates) and their trends over time. In this paper, we present the model and its application to schools in the Australian Capital Territory. We also show how the model greatly increases the capacity to understand and predict enrolment change, while increasing efficiency and reducing bias.

Abstract: Background There has been considerable speculation on whether the COVID-19 pandemic had an effect on childbearing behaviour. Based on the experience of other social and economic disruptions, many researchers suggested that births would decline, while others argued that there could be a positive effect. Aims This paper considers the uncertainties associated with the impacts of COVID-19, particularly the relationship between the timing of COVID-19 events and subsequent births. Data and methods Publicly available birth data from birth registers, perinatal databases, and public hospital data were compiled and analysed to document changes in numbers and patterns of recorded births during 2020 and 2021. Results Births declined in 2020 but then rebounded in 2021. Quarterly birth data from New South Wales and Western Australia suggest that the sharpest drop in conceptions occurred in the January-March 2020 quarter. This coincided with the period when the pandemic was first taking off and when uncertainty about the future was at its highest. Conclusions The uncertainty associated with the onset of the COVID-19 pandemic had a noticeable impact on births in 2020. It also shows, where data is available, that this impact was relatively short-lived, and births rebounded in 2021. We note that data is still sparse for Victoria, a state which was substantially more affected by lockdowns.

Abstract: Using longitudinal data from Australia we compare the wellbeing effects of transitions both into and out relationships, using two different measures of wellbeing: life satisfaction and mental health. We distinguish between the formation, and ending of, three different types of relationships across three years: Living-apart-together (LAT), cohabitations, and marriages. For those in LAT relationships, we find they are quite distinct from other ‘single’ people. Starting, or ending, a LAT relationship has a significant impact on an in idual’s wellbeing. We also find that transitions into relationships, and transitions out of relationships, do not have equivalent effects. Generally, moving from a relationship to being single had a more significant negative impact on life satisfaction and mental health, than moving into a relationship had a positive impact. These findings suggest that having an intimate partner, even one who is not co-resident, is related to higher levels of wellbeing compared to having no partner.

Abstract: Heterogeneous teams of robots, leveraging a balance between autonomy and human interaction, bring powerful capabilities to the problem of exploring dangerous, unstructured subterranean environments. Here we describe the solution developed by Team CSIRO Data61, consisting of CSIRO, Emesent, and Georgia Tech, during the DARPA Subterranean Challenge. These presented systems were fielded in the Tunnel Circuit in August 2019, the Urban Circuit in February 2020, and in our own Cave event, conducted in September 2020. A unique capability of the fielded team is the homogeneous sensing of the platforms utilized, which is used to obtain a decentralized multi-agent SLAM solution on each platform (both ground agents and UAVs) using peer-to-peer communications. This approach enabled a shift in focus from constructing a pervasive communications network to relying on multi-agent autonomy, motivated by experiences in early circuit events. These experiences also showed the surprising capability of rugged tracked platforms for challenging terrain, which in turn led to the heterogeneous team structure based on a BIA5 OzBot Titan ground robot and an Emesent Hovermap UAV, supplemented by smaller tracked or legged ground robots. The ground agents use a common CatPack perception module, which allowed reuse of the perception and autonomy stack across all ground agents with minimal adaptation.
