Citizen scientists track a charismatic carnivore: Mapping the spread and impact of the South African Mantis (Miomantidae, Miomantis caffra) in Australia

The recent integration of citizen science with modern technology has greatly increased its applications and has allowed more people than ever to contribute to research across all areas of science. In particular, citizen science has been instrumental in the detection and monitoring of novel introduced species across the globe. This study provides the first records of Miomantis caffra Saussure, 1871, the South African Mantis, from the Australian mainland and uses records from four different citizen science and social media platforms in conjunction with museum records to track the spread of the species through the country. A total of 153 wild mantises and oothecae were observed across four states and territories (New South Wales, Norfolk Island, Victoria, and Western Australia) between 2009 and 2021. The large number of observations of the species in Victoria and the more recent isolated observations in other states and territories suggest that the species initially arrived in Geelong via oothecae attached to plants or equipment, likely from the invasive population in New Zealand. From there it established and spread outwards to Melbourne and eventually to other states and territories, both naturally and with the aid of human transport. We also provide a comparison of M. caffra to similar native mantises, specifically Pseudomantis albofimbriata (Stål, 1860), and comment on the potential impact and further spread of the species within Australia. Finally, we reiterate the many benefits of engaging directly with citizen scientists in biodiversity research and comment on the decision to include them in all levels of this research investigation.

Japanese Encephalitis Outbreak in South-Eastern Australia, 2022

In February and March 2022, an outbreak of Japanese Encephalitis Virus (JEV) was detected in piggeries in southern Queensland, NSW, Victoria and South Australia. Subsequently, human cases of JEV have been confirmed in each of the affected states, with 35 confirmed or probable cases and 3 deaths as of 7 April 2022. This is the first JEV outbreak in mainland Australia. JEV has not been detected in mosquitos, animals or humans in south-Eastern Australia previously and question remain about how it became established, and whether it will become endemic to this region. The majority of cases are occurring around the affected piggeries where there is exposure to mosquitoes, particularly in the older age group, and vaccination has commenced in this population.

The Northwest Offshore Otway Basin Well Folio

The Otway Basin is a northwest–southeast trending rift basin which spans from onshore Victoria and South Australia into the deep-water offshore. The prospective supersequences within the basin are largely of Cretaceous age that host three possible petroleum systems (Austral 1, 2 and 3). While there is production from onshore depocentres, and the inboard Shipwreck Trough, the majority of the offshore basin remains underexplored. Recent regional studies have highlighted the need for further work across the underexplored parts of the basin and here we focus on the offshore northwest Otway Basin, integrating reinterpreted historical well data, newly acquired and recently reprocessed seismic data. This new Well Folio consists of composite logs and supporting data, which includes interpreted lithologies, petrophysical analyses, the analysis of historic organic geochemistry and organic petrology. In addition, updated well markers are provided based on seismic interpretation and new biostratigraphy in key wells. This integrated study provides the basis for renewed prospectivity assessment in the northwest offshore portion of the Otway Basin.

Public willingness to make trade-offs in the development of a hydrogen industry in Australia

Hydrogen is attracting increasing attention and investment in the low carbon energy transition. However, it is expected that any transition to hydrogen at a meaningful scale or rate, will be dependent on the industry obtaining a social licence, underpinned by public acceptance. This study analyses responses from a public survey that asked 1,824 residents of South Australia and Victoria (Australia) to indicate how important six characteristics of a hydrogen industry would be in their decision to support the development of such an industry, namely: (1) safety; (2) climate change mitigation; (3) affordability; (4) reliability; (5) accessibility; and (6) job creation. Overall, safety was rated as the most important characteristic, followed by climate change mitigation and affordability. Fractional multinomial logit model estimates found socio-demographic (e.g. age, location) and attitudinal characteristics (e.g. concern about climate change, hydrogen knowledge) statistically significantly influenced individuals’ importance ratings of hydrogen industry characteristics. This research indicates the trade-offs that individuals may—or may not be—willing to make in the transition to hydrogen energy. Such information can be used to align policy and investment decisions with public expectations for the further development of the hydrogen industry in Australia.

Multi-period vaccine allocation model in a pandemic: A case study of COVID-19 in Australia

While the swift development and production of a COVID-19 vaccine has been a remarkable success, it is equally crucial to ensure that the vaccine is allocated and distributed in a timely and efficient manner. Prior research on pandemic supply chain has not fully incorporated the underlying factors and constraints in designing a vaccine allocation model. This study proposes an innovative vaccine allocation model to contain the spread of infectious diseases incorporating key contributing factors to the risk of uninoculated people including susceptibility rate and exposure risk. Analyses of the data collected from the state of Victoria in Australia show that a vaccine allocation model can deliver a superior performance in minimizing the risk of unvaccinated people when a multi-period approach is employed and augmenting operational mechanisms including transshipment between medical centers, capacity sharing, and mobile units being integrated into the vaccine allocation model.

An approach to investigate the supplementary inconsistency between time series data for predicting road pavement performance models

ABSTRACT Road agencies commonly face high level complexity of comprehensive pavement maintenance scheduling complications. This could be due to uncertainty of some parameters that substance in the predicting models. Disregarding this uncertainty of such parameters in the road maintenance scheduling problems may lead to imprecise solutions and unreliable road conditions. Frequently time series data that have a hierarchical structure are used for predicting road surface or pavement structure distresses models. However, further realistic and accurate predicted models are those consider supplementary inconsistency between time series data with utilising a predictive approach that imposes knowledge of the input parameters. The purpose of this study is to test this theory by comparing the predictions of models developed using two approaches and their accuracies in utilising the same data. These approaches are the traditional regression model (TRM) with only one level of heterogeneity approach and the hierarchical regression model (HRM) with many levels of heterogeneities approach. A Metro North Western (MNW) urban road network in Victoria (Australia) was considered as the case study for this study investigation where covering the condition of approximately 305 Km of asphalt surfaced pavements. By considering the structure of time series data, the study revealed that more accurate models could predict the pavement behaviour, the deterioration rate, and significantly influenced parameters. In addition, the study highlighted that it is essential to deliberate and process the hierarchical structure of datasets to consider the observed and unobserved heterogeneities in time series data for developing any pavement performance model using either deterministic or probabilistic prediction approaches. Multiple simulation scenarios have been performed for both approaches and the HRM approach shows more reasonable outputs. For predicted deterministic SIR models, road intervention (SIR ≥ 20) are triggered at age 12.5 when using TRM approach and at age 10.5 when using HRM approach. For predicted probabilistic SIR models, the surface condition of a section with SIR weighted average condition values of 2 is triggered at age 17.5 when using TRM approach and at age 10.5 when using HRM approach. This also refers to earlier maintenance scheduling is required when using the later approach because it deals confidentially with each road sections time series data. In that regard, ignoring the uncertainty in time series data of such factors in the road surfacing maintenance scheduling problems may lead to suboptimal solutions and unstable pavement conditions.

Climate Emergencies in Australian Local Governments: From Symbolic Act to Disrupting the Status Quo?

This paper examines the emerging phenomenon of climate emergency declarations. We focus on the case of Victoria Australia and the 30 councils who have declared a climate emergency with a particular focus on three councils. We explore the drivers, meanings, and implications and to what extent the subsequent plans reflect a reframing of local government roles and actions. We find the emergency declaration movement is catalysing councils beyond symbolic declarations potentially opening up space for change and disruption. Of interest in this paper is also the principal and theoretical implications for citizens, local government, and for research that is connected with this emerging trend. We highlight conclusions, ideas, and perspectives that can be drawn from this study of the Australian practice of climate emergency declarations.

Consumer involvement in research – parent perceptions of partnership in cerebral palsy research: a qualitative study

Purpose Identify perceptions of parents and caregivers of children with cerebral palsy about being consumer research partners and identify strategies to inform involvement of parents in cerebral palsy research. Materials and methods Twenty-two parents in New South Wales and Victoria (Australia) participated in this qualitative study. Seven interviews and three focus groups were completed. Interpretive description guided data analysis. Methodological rigor was enhanced through involving two consumer investigators in the research team, member checking, and multiple researchers completing data analysis and theme generation. Results Participants identified a range of factors that may influence their involvement in research partner roles. Main topics emerging from the data included “Research Is Better with Parents” and “Parents Benefit from Being Research Partners.” A third, “Parents as Research Partners,” contained the themes “Flexible Involvement,” “Starting Partnerships,” and “Building and Sustaining Partnerships.” Conclusion This study has provided a rich insight into how parents perceive and describe engaging as research partners. Parent-identified guidance will inform future partnerships aiming to enhance the quality of cerebral palsy research and outcomes for people with cerebral palsy and their families. The involvement of consumer investigators in this study was considered valuable for enhancing the quality and applicability of the research. IMPLICATIONS FOR REHABILITATION Parents believed that parent partnership in research has benefits for the research and for the consumers involved. Parents provided guidance about the importance of starting, building and sustaining relationships in involving parents as research partners. Understanding the parent context, investing in relationships and acknowledgement of, and recognition for, contributions were considered important for building and sustaining effective partnerships. Flexible approaches to supporting parents as research partners was considered necessary for effective partnership.

Workplace Experiences of Women With Disability in Sport Organizations.

Women with disability often experience barriers to employment and career progression, most notably in hyper-masculinised industry sectors such as sport. Applying an intersectionality lens and insights from critical disability theory, this research explores the lived experiences of eight women with varying types of disability through their stories of working and volunteering in sport organizations in Victoria (Australia). Analyses of the interviews highlighted the importance that these women attached to their identity as a woman with disability and the intrapersonal and organizational factors that impacted on initial sport workplace attraction and retention. The findings discuss the relationship management strategies adopted to manage these factors in workplace interactions. The interactive effect between disability and gender contributes to building a meaningful understanding of the intersectionality for women with disability in sport organizations.

How can the education sector support children’s mental health? Views of Australian healthcare clinicians

ObjectivesPolicy makers in developed countries have long considered the education system an avenue for supporting mental health care for children. Whilst educators have identified many challenges to providing this support (e.g. non-core role, stigma, overcrowded curriculum), understanding clinicians’ views on the role of educators and schools and how clinicians and schools could work together to achieve good mental health outcomes are important questions. However, clinician voices in how schools and health should work together for children’s mental health care are frequently missing from the debate. We aimed to report clinicians’ views about how the education system could support student’s mental health and improve access to mental health care for children and adolescents.Methods143 clinicians (approximately 35 each of child and adolescent psychiatrists, pediatricians, child psychologists and general practitioners (GPs)) from the states of Victoria and South Australia participated in semi-structured phone interviews between March 2018 and February 2019. Inductive content analysis was applied to address the broad study aims.FindingsKey themes emerged: (1) The role of schools in supporting individual children; (2) School based programs to support children and families; and (3) Challenges of implementing these suggestions. Clinicians across all professional groups suggested the education system could play an important role in improving access to mental health services through harnessing existing staff or co-locating mental health clinicians. They also suggested schools could identify at risk children and implement coping and social skills programs.ConclusionsSchools and educators could play a key role in prevention and early intervention of children’s mental health problems. However, before recommending exactly how to do this, key evidence gaps need to be addressed.

Framing the Care of Injured Workers: An Empirical Four-Jurisdictional Comparison of Workers' Compensation Boards' Healthcare Policies.

The objective of this study was to explore how workers' compensation policies related to healthcare provision for workers with musculoskeletal injuries can affect the delivery and trajectories of care for injured workers. The principal research question was: What are the different ways in which workers' compensation (WC) policies inform and transform the practices of healthcare providers (HCPs) caring for injured workers? We conducted a cross-jurisdictional policy analysis. We conducted qualitative interviews with 42 key informants from a variety of perspectives in the provinces of Ontario and Quebec in Canada, the state of Victoria in Australia and the state of Washington in the United States. The main methodological approach was Framework Analysis. We identified two main themes: (1) Shaping HCPs' clinical practices and behaviors with injured workers. In this theme, we illustrate how clinical practice guidelines and non-economic and economic incentives were used by WCs to drive HCP's behaviours with workers; (2) Controlling workers' trajectories of care. This theme presents how WC policies achieve control of the workers' trajectory of care via different policy mechanisms, namely the standardization of care pathways and the power and autonomy vested in HCPs. This policy analysis shed light on the different ways in which WC policies shape HCP's day-to-day practices and workers' trajectories. A better understanding and a nuanced portrait of these policies' impacts can help support reflections on future policy changes and inform policy development in other jurisdictions.

Outpatient Parenteral Antimicrobial Therapy (OPAT) Program for Infective Endocarditis in North Queensland

Optimal treatment of infective endocarditis is an ongoing challenge. Evidence from Victoria in Australia has suggested outpatient parenteral antimicrobial therapy (OPAT) is safe for use in infective endocarditis (IE). However, data from Townsville and Darwin regions demonstrated solution temperatures from home intravenous infusions significantly differ from stability data, tested at room temperature [1]. It is not clear if this is clinically significant; therefore, it is prudent to examine the outcomes of hospital readmission and mortality of OPAT patient cohorts living in high temperature climates.

Mandatory TNM Staging of Breast Cancer and Harms of mammographic Screening

In Australia and many other high and middle-income countries diagnosis of the most curable stages of breast cancer, early breast cancer (EBC), in women by population based mammographic screening began after 1990. In many of these same and other high and middle-income countries administering adjuvant endocrine and chemotherapy after surgical complete resection of EBC (adjuvant therapy) also began in the 1990s. Some populations then underwent declines in breast cancer mortality that were recorded in population-based Cancer Registries that were attributed to either mammographic screening and/or adjuvant therapy. In only a few populations, for example, in the State of Victoria Australia from 1986-2019 long term trends in the incidence of breast cancer stages at diagnosis have been recorded by the population-based Victorian Cancer registry (VCR). These long-term stage trends have shown that advanced stages of breast cancer have increased or remained stable in those populations, so mammographic screening could not have directly caused the recorded declines in breast cancer mortality in their population-based Cancer Registries. In contrast in Victoria Australia adjuvant therapy use can explain all the recorded mortality decline.

Japanese encephalitis virus: an emerging and re-emerging virus in Australia

Japanese encephalitis virus (JEV) first emerged in the Torres Strait of north-eastern Australia in 1995, with three human cases, and widespread infection of pigs on a number of islands. The virus was shown to belong to genotype II. Further cases occurred in 1998, including the first case on mainland Australia on Cape York. A second genotype of JEV, genotype Ia, was reported in mosquitoes and pigs in 2000–04, possibly displacing genotype II. JEV re-emerged in Australia with a fatal human case on the Tiwi Islands, Northern Territory, in 2021, and shown to belong to genotype IV. This case was followed about a year later by a large outbreak of JE; first detected in piggeries in four states, Queensland, New South Wales, Victoria, and South Australia, resulting in reproductive losses affecting 80 piggeries and 42 human cases, with seven fatal cases. The wide geographic spread of cases suggested that the virus had been circulating for a number of months or even years prior to detection, and has led to significant concern that the virus will become endemic to Australia, in a similar ecology to Murray Valley encephalitis virus. Known competent mosquito vectors and ardeid birds, as maintenance hosts, occur in Australia, and it is probable that feral pigs will provide an additional wildlife reservoir of virus. Little is known of the properties of genotype IV, but it is expected to have a similar ecology and pathogenesis to other JEV genotypes.

Sexual behaviour during COVID-19: a repeated cross-sectional survey in Victoria, Australia.

During 2020, the State of Victoria (Australia) experienced two COVID-19 waves. Both resulted in community lockdowns followed by eased restrictions. We examined variation of sexual behaviour in Victorians over time during COVID-19. We conducted a repeated online survey at four timepoints corresponding with two lockdown (LD1, LD2) and two reduced restriction (RR1, RR2) periods in Victoria. A convenience sample of participants aged ≥18years was recruited via social media and asked about their recent (past 4weeks) sexual behaviour. Using multivariable logistic regression, we investigated variation in sexual behaviour between surveys. A total of 1828 surveys were completed; 72% identified as female, 69% were aged 18-29years, 90% were metropolitan residents. The proportion reporting recent partnered sex ranged from 54.9% (LD2) to 70.2% (RR1). Across all timepoints, the most common sexual partners were regular (81.5%, n =842) and 10.8% (n =111) reported casual partners (e.g. hook-ups). Compared with LD1, respondents were >2-fold more likely to report casual partner(s) during reduced restrictions (RR1: aOR 2.0; 95% CI 1.1-3.7; RR2: aOR 2.8; 95% CI 1.3-5.9). Across all timepoints, 26.6% (n =486) reported using dating apps. Compared with LD1, dating app use for face-to-face activities (e.g. dates, hook-ups) was >4-fold higher during reduced restrictions (RR1: aOR 4.3; 95% CI 2.3-8.0; RR2: aOR 4.1; 95% CI 1.9-8.8). App use for distanced activities (e.g. sexting, virtual dates) was highest during LD1 (48.8%) than other periods. In this convenience sample, self-reported sexual behaviours fluctuated between lockdowns and reduced restrictions. While dating apps may provide a mechanism for virtual connections, this may be temporary until physical connections are possible.

Detection of Ramularia collo-cygni from barley in Australia using triplex quantitative and droplet digital PCR.

Ramularia leaf spot (RLS), caused by Ramularia collo-cygni, is an emerging threat to barley (Hordeum vulgare L.) production. RLS has been reported in Australia, however only minimal information is available regarding its detection and distribution. Due to initial asymptomatic growth in planta, slow growth in vitro and symptomatic similarities to net blotch and physiological leaf spots, detection of this pathogen can be challenging. Quantitative polymerase chain reaction (PCR)-based methods for R. collo-cygni-specific identification and detection have been described, however these assays have been demonstrated to lack specificity. False-positive detections may have serious implications, thus we aimed to design a robust R. collo-cygni-specific PCR method. Using the phylogenetically informative RNA polymerase II second largest subunit (rpb2) and translation elongation factor 1-alpha (tef1-α) genes, along with the tef1-α gene of H. vulgare, a triplex assay was developed for both quantitative and droplet digital PCR. The triplex assay detected R. collo-cygni DNA in barley leaves from New South Wales, South Australia, Tasmania, Victoria and Western Australia. No R. collo-cygni DNA was detected in barley seed grown in Western Australia. The presence of R. collo-cygni DNA has been confirmed in Australian barley crops, suggesting a distribution ranging across the southern barley growing regions of Australia. The R. collo-cygni-specific assay will be a valuable tool to assist with monitoring the distribution and impact of R. collo-cygni in Australia and other regions. © 2021 Society of Chemical Industry.
