Natural hazards, such as bushfires, cyclones, floods, storms, heatwaves, earthquakes and tsunamis, have always occurred and will continue to occur in Australia. These natural hazards frequently intersect with human societies to create natural hazard emergencies that, in turn, cause disasters.

The effects of natural hazards on Australian communities are influenced by a unique combination of social, economic, natural environment, built environment, governance and geographical factors.

Australian communities face increasing losses and disruption from natural hazards, with the total economic cost of natural hazards in Australia averaging $18.2 billion per year between 2006 and 2016 (Deloitte Access Economics, 2017). This is expected to almost double by 2030 and to average $33 billion per year by 2050 (Deloitte Access Economics, 2016). The social impacts of disasters are also substantial. Costs associated with social impacts may persist over a person’s lifetime and can be greater than the costs of tangible damages (Deloitte Access Economics, 2016).

Climate change is expected to increase the frequency and magnitude of some natural hazard types in Australia (BOM & CSIRO, 2018). An increasing population, demographic change, widening socio-economic disparity, expensive infrastructure and the location of communities in areas of high natural hazard risk also contributes to the potential for increasing losses from natural hazards.

There are two prominent schools of thought about the influence of natural hazards in human societies:

• a vulnerability perspective, where distributional inequalities in physical, social, economic and environmental factors influence the susceptibility of people to harm and the ability of people to respond to hazards (Cutter et al., 2003; Birkmann, 2006; Bankoff, 2019).
• a resilience perspective, where people are learning to live with a changing, unpredictable and uncertain environment (Folke et al., 2002; Bankoff, 2019), of which natural hazards are a part. Resilience is a process linking a set of capacities to a positive trajectory of functioning and adaptation after a disturbance (Norris et al., 2008).

As such, disaster resilience can be understood as a protective characteristic that acts to reduce the effects of, and losses from, natural hazards. Resilience arises from the capacities of social, economic and government systems to prepare for, respond to and recover from a natural hazard event, and to learn, adapt and transform in anticipation of future natural hazard events.

Society has always been susceptible to natural hazards. While the occurrence of these events generally cannot be prevented, the risks can often be minimised and the impacts on people and property reduced.

Neoliberalism has wrought fundamental changes in the world of work, leading to rising inequality, substantial weakening of organised labour and a decline in industrial relations as a field, especially in relation to teaching. Drawing on historical 'big data' this paper argues that examining the history of worker mobilisation provides a better understanding of these developments, including the importance of considering diverse forms of organisation and action as well as multi-pronged methods built around a key set of issues. It can also inform efforts to address challenges posed by neoliberalism. We conclude by arguing that an historical perspective can better equip the field of industrial relations to meet challenges extending beyond the world of work.

This thesis critically examines the commensurability of the Health Services Act (1997) of New South Wales (NSW) and the Performance Agreements. The broader purpose of the study is to pursue a greater understanding of public policy implementation in the NSW public health system. This thesis traces the New England Area Health Service's Performance Agreements from 1997-2001 and focuses on the implementation process related to their achievement. Through the use of interviews with key political, bureaucratic, health professional and lobby group actors, archival material, related literature and primary other sources, the thesis identifies some of the key factors that influenced the Health Service Act's implementation process. The thesis interprets the empirical findings in the light of the theoretical literature on policy implementation, focusing particularly on Sabatier and Mazmanians' (1980) implementation framework and the relationship between New Public Management and traditional public administration. It identifies some of the ways the NSW Department of Health influenced the implementation process and the specific manifestations of commensurability between the Health Services Act and the Performance Agreements. It concludes that whilst commensurability between the Health Services Act and the Performance Agreements was evident, its achievement was somewhat tempered by the Department of Health's employment of traditional public administration practices outside the Statute in managing the implementation process essentially to reclaim lost power, position and authority that it experienced prior to the introduction of New Public Management.

Background: This section defined time use (TU) research, illustrating its relevance for public health. TUR in the health context is the study of health-enhancing and health-compromising behaviours that are assessed across a 24 h day. The central measurement is the use of Time Use Diaries, which capture 24-48 h, typically asking about behaviour in each 15-min period. TUR is used for understanding correlates of health behaviours, and as a form of population surveillance, assessing behavioural trends over time.

Main body: This paper is a narrative review examining the history of time use research, and the potential uses of TU data for public health research. The history of TUR started in studies of the labour force and patterns of work in the late 19th and early twentieth century, but has more recently been applied to examining health issues. Initial studies had a more economic purpose but over recent decades, TU data have been used to describe the distribution and correlates of health-enhancing patterns of human time use. These studies require large multi-country population data sets, such as the harmonised Multinational Time Use Study hosted at the University of Oxford. TU data are used in physical activity research, as they provide information across the 24-h day, that can be examined as time spent sleeping, sitting/standing/light activity, and time spent in moderate-vigorous activities. TU data are also used for sleep research, examining eating and dietary patterns, exploring geographic distributions in time use behaviours, examining mental health and subjective wellbeing, and examining these data over time. The key methodological challenge has been the development of harmonised methods, so population TU data sets can be compared within and between-countries and over time.

Conclusions: TUR provides new methods for examining public health research questions where a temporal dimension is important. These time use surveys have provided unique data over decades and in many countries that can be compared. They can be used for examining the effects of some large public health interventions or policies within and between countries.

Background: Over the last 150 years, advanced economies have seen the burden of disease shift to non-communicable diseases. The risk factors for these diseases are often co-morbidities associated with unhealthy weight. The prevalence of overweight/obesity among adults in the advanced countries of the English-speaking world is currently more than two-thirds of the adult population. However, while much attention has concentrated on changes in diet that might have provoked this rapid increase in unhealthy weight, changes in patterns of eating have received little attention.

Methods: This article examines a sequence of large-scale, time use surveys in urban Australia stretching from 1974 to 2006. The earliest survey in 1974 (conducted by the Cities Commission) was limited to respondents aged between 18 and 69 years, while the later surveys (by the Australian Bureau of Statistics) included all adult (15 years of age or over) living private dwellings. Since time use surveys capture every activity in a day, they contain much information about mealtimes and the patterns of eating. This includes duration of eating, number of eating occasions and the timing of eating. Inferential statistics were used to test the statistical significance of these changes and the size of the effects.

Results: The eating patterns of urban Australian adults have changed significantly over a 32-year period and the magnitude of this change is non-trivial. Total average eating time as main activity has diminished by about a third, as have eating occasions, affecting particularly luncheon and evening meals. However, there is evidence that eating as secondary activity that accompanies another activity is now almost as frequent as eating at mealtimes. Moreover, participants seem not to report it.

Conclusions: Contemporary urban Australians are spending less time in organized shared meals. These changes have occurred the over same period during which there has been a public health concern about the prevalence of unhealthy weight. Preliminary indications are that societies that emphasize eating as a commensal, shared activity through maintaining definite, generous lunch breaks and prioritizing eating at mealtimes, achieve better public health outcomes. This has implications for a strategy of health promotion, but to be sure of this we need to study countries with these more socially organized eating patterns.
