Gambling activities and the revenues derived have been seen as a way to increase economic development in deprived areas. There are also, however, concerns about the effects of gambling in general and electronic gaming machines (EGMs) in particular, on the resources available to the localities in which they are situated. This paper focuses on the factors that determine the extent and spending of community benefit-related EGM-generated resources within Victoria, Australia, focusing in particular on the relationships between EGM activity and socio-economic and social capital indicators, and how this relates to the community benefit resources generated by gaming.

In Thomas Mann’s tetralogy of the 1930s and 1940s, Joseph and His Brothers, the narrator declares history is not only “that which has happened and that which goes on happening in time,” but it is also “the stratified record upon which we set our feet, the ground beneath us.” By opening up history to its spatial, geographical, and geological dimensions Mann both predicts and encapsulates the twentieth-century’s “spatial turn,” a critical shift that divested geography of its largely passive role as history’s “stage” and brought to the fore intersections between the humanities and the earth sciences. In this paper, I draw out the relationships between history, narrative, geography, and geology revealed by this spatial turn and the questions these pose for thinking about the disciplinary relationship between geography and the humanities. As Mann’s statement exemplifies, the spatial turn itself has often been captured most strikingly in fiction, and I would argue nowhere more so than in Graham Swift’s Waterland (1983) and Anne Michaels’s Fugitive Pieces (1996), both of which present space, place, and landscape as having a palpable influence on history and memory. The geographical/geological line that runs through both Waterland and Fugitive Pieces continues through Tim Robinson’s non-fictional, two-volume “topographical” history Stones of Aran. Robinson’s Stones of Aran—which is not history, not geography, and not literature, and yet is all three—constructs an imaginative geography that renders inseparable geography, geology, history, memory, and the act of writing.

This contribution outlines Synchrotron-based X-ray micro-tomography and its potential use in structural geology and rock mechanics. The paper complements several recent reviews of X-ray microtomography. We summarize the general approach to data acquisition, post-processing as well as analysis and thereby aim to provide an entry point for the interested reader. The paper includes tables listing relevant beamlines, a list of all available imaging techniques, and available free and commercial software packages for data visualization and quantification. We highlight potential applications in a review of relevant literature including time-resolved experiments and digital rock physics. The paper concludes with a report on ongoing developments and upgrades at synchrotron facilities to frame the future possibilities for imaging sub-second processes in centimetre-sized samples.

Marine sediments around volcanic islands contain an archive of volcaniclastic deposits, which can be used to reconstruct the volcanic history of an area. Such records hold many advantages over often incomplete terrestrial datasets. This includes the potential for precise and continuous dating of intervening sediment packages, which allow a correlatable and temporally-constrained stratigraphic framework to be constructed across multiple marine sediment cores. Here, we discuss a marine record of eruptive and mass-wasting events spanning ~250 ka offshore of Montserrat, using new data from IODP Expedition 340, as well as previously collected cores. By using a combination of high-resolution oxygen isotope stratigraphy, AMS radiocarbon dating, biostratigraphy of foraminifera and calcareous nannofossils and clast componentry, we identify five major events at Soufriere Hills volcano since 250 ka. Lateral correlation of these events across sediment cores collected offshore of the south and south west of Montserrat, have improved our understanding of the timing, extent and associations between events in this area. Correlations reveal that powerful and potentially erosive density-currents travelled at least 33 km offshore, and demonstrate that marine deposits, produced by eruption-fed and mass-wasting events on volcanic islands, are heterogeneous in their spatial distribution. Thus, multiple drilling/coring sites are needed to reconstruct the full chronostratigraphy of volcanic islands. This multidisciplinary study will be vital to interpreting the chaotic records of submarine landslides at other sites drilled during Expedition 340 and provides a framework that can be applied to the stratigraphic analysis of sediments surrounding other volcanic islands.

This is the second volume of a five volume series that describes, assesses, and analyses football in Victoria during the nineteenth century. This volume looks at the cultural contexts of the sport in the late 1870s and early 1880s, describes the important matches played, and provides a full statistical account of this time period. This book is the first comprehensive discussion of the early period in Australian football's development.

This research first asks ‘What happens when young people leave state care?’ in respect of Victoria and Queensland and second ‘What are the service support implications of this?’ A number of methods were used to explore these questions including semi-structured interviews with 27 young adults aged 19-23 years who had been homeless or at risk of homelessness, and focus groups with young people and service providers. This study provides support for the proposition that young people should be proactively and voluntarily involved in periodic monitoring of their lived experience post care and linkage of this monitoring to the activation of timely support. The great majority of young people involved in this study thought this was not only desirable but important. Whilst some young people will be in close contact with leaving care services many others will not. New research is recommended to develop a mentoring and support activation process using participatory monitoring and action research methods. This type of approach reflects the importance of utilising processes with young people in care and leaving care which acknowledge their personhood and capacity to contribute voluntarily to the processes which seek to support them.

Christy Dena was commissioned by the Australia Council for the Arts to organise and curate a special conference and workshop event on transmedia. Her brief was to secure all the relevant funding bodies to support it financially (the first time they ever all funded the same event). Christy brought in transmedia professionals from around the world, and targeted directors, writers, designers, and producers, from film, TV, theatre, gaming, music, literature and digital sectors. She curated the audience as well as the speakers. It was a huge success, and follow-up meetups with the IGDA were also organised.

Objectives Commercial sex is licensed in Victoria, Australia such that sex workers are required to have regular tests for sexually transmitted infections (STIs). However, the incidence and prevalence of STIs in sex workers are very low, especially since there is almost universal condom use at work. We aimed to conduct a cost-effectiveness analysis of the financial cost of the testing policy versus the health benefits of averting the transmission of HIV, syphilis, chlamydia and gonorrhoea to clients. Methods We developed a simple mathematical transmission model, informed by conservative parameter estimates from all available data, linked to a cost-effectiveness analysis. Results We estimated that under current testing rates, it costs over $A90 000 in screening costs for every chlamydia infection averted (and $A600 000 in screening costs for each quality-adjusted life year (QALY) saved) and over $A4 000 000 for every HIV infection averted ($A10 000 000 in screening costs for each QALY saved). At an assumed willingness to pay of $A50 000 per QALY gained, HIV testing should not be conducted less than approximately every 40 weeks and chlamydia testing approximately once per year; in comparison, current requirements are testing every 12 weeks for HIV and every 4 weeks for chlamydia. Conclusions Mandatory screening of female sex workers at current testing frequencies is not cost-effective for the prevention of disease in their male clients. The current testing rate required of sex workers in Victoria is excessive. Screening intervals for sex workers should be based on local STI epidemiology and not locked by legislation.

This book reports on an empirically-based study of the manner in which the Magistrates' Courts in Victoria, construct occupational health and safety (OHS) issues when hearing prosecutions for offences under the Victorian OHS legislation. Prosecution has always been a controversial element in the enforcement armoury of OHS regulators, but at the same time it has long been argued that the low level of fines imposed by courts has had an important chilling effect on the OHS inspectorate's enforcement approaches, and on the impact of OHS legislation. Using a range of empirical research methods, including three samples of OHS prosecutions carried out in the Victorian Magistrates' Courts, Professor Johnstone shows how courts, inspectors, prosecutors and defence counsel are involved in filtering or reshaping OHS issues during the prosecution process, both pre-trial and in court. He argues that OHS offences are constructed by focusing on "events", in most cases incidents resulting in injury or death. This "event-focus" ensures that the attention of the parties is drawn to the details of the incident, and away from the broader context of the event. During the court-based sentencing process defence counsel is able to adopt a range of techniques which isolate the incident from its micro and macro contexts, thereby individualising and decontextualising the incident.

This thesis reports on an empirically based study of the manner in which Victorian Magistrates Courts constructed occupational health and safety (OHS) issues when hearing prosecutions for offences under the Industrial Safety, Health and Welfare Act 1981 (the ISHWA) and the Occupational Health and Safety Act 1985 (OHSA) from 1983 to 1991. These statutes established OHS standards for employers and other relevant parties. The State government enforced these standards through an OHS inspectorate which had a range of enforcement powers, including prosecution. After outlining the historical development of Victoria’s OHS legislation, the magistracy’s historical role in its enforcement, and the development of an enforcement culture in which inspectors viewed prosecution as a last resort, the study shows how the key provisions of the ISHWA and OHSA required occupiers of workplaces and employers to provide and maintain safe systems of work, including the guarding of dangerous machinery. Using a wide range of empirical research methods and legal materials, it shows how the enforcement policies, procedures and practices of the inspectorate heavily slanted inspectors workplace investigations and hence prosecutions towards a restricted and often superficial, analysis of incidents (or “events”) most of which involved injuries on machinery. There was evidence, however, that after the establishment of the Central Investigation Unit in 1989 cases were more thoroughly investigated and prosecuted. From 1990 the majority of prosecutions were taken under the employer’s general duty provisions, and by 1991 there was evidence that prosecutions were focusing on matters other than machinery guarding.
