On fractional spherically restricted hyperbolic diffusion random field
No full textThe paper investigates solutions of the fractional hyperbolic diffusion equation in its most general form with two fractional derivatives of distinct orders. The solutions are given as spatial–temporal homogeneous and isotropic random fields and their spherical restrictions are studied. The spectral representations of these fields are derived and the associated angular spectrum is analysed. The obtained mathematical results are illustrated by numerical examples. In addition, the numerical investigations assess the dependence of the covariance structure and other properties of these fields on the orders of fractional derivatives.</p
Virtual nursing in residential aged care: What is known?
No full textThis literature review was conducted to inform the evaluation of the Virtual Nursing in Aged Care project, funded by the Department of Health and Aged Care, which will be implemented from 2024 to 2027 to optimise clinical care outcomes for older people living in residential aged care.La Trobe University has been contracted to conduct an evaluation of the project. The evaluation plan comprises four stages. As a deliverable resulting from Stage 1 of the project, a rapid literature review was conducted to scope current evidence for virtual nursing care interventions or programs in long-term residential aged care homes (RACHs).</p
Abortion, decriminalisation and the medico-legal paradigm
No full textThe medico-legal paradigm enmeshes legal with medical power, making abortion lawfully available only under the supervision of medical professionals. This article examines the recent parliamentary debates over abortion decriminalisation in New South Wales, Australia's most populous state, to argue that the decriminalisation of abortion in Australia represents a continuance with, rather than a break from, the medico-legal paradigm. The medical power embedded in laws that criminalised abortion in the nineteenth century, and liberalised abortion in the twentieth century, was not the same as that imagined by parliamentarians debating decriminalising abortion in the twenty-first century. Norms constituting abortion seekers and their doctors have shifted significantly. Nevertheless, the medico-legal paradigm continues to govern how lawful abortion is imagined. The medico-legal paradigm converts abortion seekers' desires for abortion into a need for healthcare and imagines the autonomy and agency of abortion seekers as enabled only through their subjection to medical power. This conversion, I suggest, dampens the potential abortion holds to open up and challenge norms of gender, sexuality and reproduction.</p
ASEAN-Australia Maritime Cooperation Forum Report

Theoretical and earthquake-induced groundwater chemistry changes: A perspective
No full textTo minimize the loss of life caused by earthquakes, it is crucial to have early warning tools that provide sufficient warning time. Although various methods are available, their accuracy is uncertain. This review explores alternative indicators related to hydrogeochemical anomalies that appear before earthquakes, which could potentially offer earlier warnings. It presents a theoretical basis for ionic and molecular changes initiated by the generation of hydroxyl radicals (•OH) and hydrogen peroxide (H2O2) in groundwater before an earthquake. The review analyses 32 earthquake events by measuring ionic anomalies through standard reduction potential. The study also identifies significant pre-seismic erosional activity in minerals exposed to hydrogen peroxide. Additionally, the oxidation of organic compounds is shown to predict notable geochemical changes. The changes in the groundwater chemistry can also be validated by examining simultaneous microbial/ zooplankton responses. The findings suggest that the ionic, mineral, organic, and microbiological changes triggered by hydroxyl radicals and hydrogen peroxide could serve as a multi-parametric earthquake early-warning system. Implementation of such a system could improve the accuracy and timeliness of earthquake warning systems potentially reducing the associated risks and damages.</p
RESPOND - Alcohol and other drug-facilitated sexual violence in Bendigo
No full textThe RESPOND project aimed to build community capacity to prevent and respond to drink spiking related sexual violence in the Greater Bendigo region. The project used a multi-stakeholder participatory action and co-design approach to develop and evaluate a community-based resource for bar staff to prevent and appropriately respond to drink spiking.</p
A scoping review of interventions targeting the mental health of Australian veterans
No full textServing in the military can have significant impacts on the mental health of veterans and their families. Military personnel can be exposed to a range of physical stressors, psychological trauma, risky lifestyle factors, a regimented military culture, and inadequate support when transitioning out of service. This article reviews research on interventions designed to improve the mental health of Australian military veterans in order to synthesise current knowledge and identify gaps in the literature. Our scoping review followed PRISMA recommendations and comprised peer-reviewed literature published since 2000. The review demonstrates a dominance of psychologically driven research paradigms and interventions and a neglect of the importance of social factors in shaping veteran mental health. There is a wide range of interventions available; however, the literature is narrow and limited. We found little evidence that the lived experience of veterans had been harnessed in program design or delivery. We argue the need for a holistic approach that moves beyond psychological and biological understandings of health and wellbeing to incorporate social and cultural determinants. Future research could adopt a stronger multidisciplinary approach, increased socio-cultural understanding, and greater consideration of the lived experience of veterans and their families
Cognitive status correlates of subclinical action tremor in female carriers of FMR1 premutation
No full textBackground: There is evidence for a significant excess of kinetic upper limb tremor in non-FXTAS female FMR1 premutation carriers. The present study explores the possibility that this tremor is associated with various other features reminiscent of those occurring in syndromic FXTAS. Sample/methods: This study analyzed the data from an Australian cohort of 48 asymptomatic premutation women. We utilized spiral drawings from CRST, representing action tremor; the CRST total tremor; and ICARS- kinetic tremors/cerebellar ataxia scales. Cognitive tests (involving executive functioning) included SDMT, TMT, two subtests of the WAIS-III: MR and Similarities. Spearman Rank correlations assessed the relationships between the above measures, and the Chi-square tested hypothesis about the association between the white matter hyperintensities (wmhs) in the splenium of corpus callosum assessed from MR images and spiral drawings scores. Results: The spiral drawing scores were significantly correlated with all three non-verbal cognitive test scores, and with the CRST scores; the latter correlated with all four cognitive test measures. Similarities (verbal) scores correlated with CRST, ICARS, and with the remaining cognitive scores. Ordered spiral scores’ categories were significantly associated with the degree of splenium involvement. Conclusion: This study showed that, in non-FXTAS premutation female carriers, sub-symptomatic forms of kinetic tremor were associated with a broader motor, and cognitive (especially executive) dysfunction
Examining the impact of tourists’ hope, knowledge and perceived value on online hotel booking intentions
No full textResearch has previously established that tourists assess “attributes’ to appraise the value a hotel may offer before booking online. However, this rational approach overlooks the role emotions may play in the decision-making process. This research examines the positive emotion of hope. Study 1 involved an experiment of 259 North American tourists, confirming the causal relationship between “hope” and “perceived value”. Study 2 involved an online survey of 418 North American hotel guests, demonstrating “brand knowledge” moderates the relationship between hope and guests’ perceived value, leading to booking intentions. These findings contribute new knowledge for tourism practitioners and researchers
