- Description: Bourdieu's analytic concept of habitus has provided a valuable means of theorising coach development but is yet to be operationalised in empirical research. This article redresses this oversight by drawing on a larger study that inquired into how the 'coaching habitus' of elite-level Australian and New Zealand rugby coaches structured their interpretation and use of the Game Sense approach to coaching to illustrate how habitus can be operationalised. It focuses on the identification of characteristics of the individual coaching habitus of four elite-level Australian rugby coaches and how they shape their interpretation and use of Game Sense. Drawing on suggestions made by Lau, we identify the characteristics of four individual 'coaching habitus' by examining their views on: (1) the characteristics of good coaches; (2) characteristics of great rugby players and how to develop them; and (3) their dispositions towards innovation in coaching. © 2013 Copyright Taylor and Francis Group, LLC.

- Description: Background: Insulin resistance has been postulated to play a central role in the co-appearance of various cardiovascular disease risk factors constituting the metabolic syndrome (MetS). There is evidence that altered cardiac autonomic function (CAF) may precede the onset of insulin resistance. Exercise training has been shown to improve CAF in different populations, yet little is known regarding the exercise dose response for CAF. The aim of this study was to investigate the impact of different volumes of high-intensity interval training (HIIT) and traditional moderate-intensity continuous training (MICT) on CAF in participants with MetS. Methods: Individuals with MetS (n=56) were randomised into the following 16-week training interventions: i) MICT (n=16, 30min at 60-70%HRpeak, 5×/week); ii) 4HIIT (n=19, 4×4min bouts at 85-95%HRpeak, interspersed with 3min of active recovery at 50-70%HRpeak, 3×/week); or iii) 1HIIT (n=21, 1×4min bout at 85-95%HRpeak, 3×/week). R-R interval recorded for 5min in a supine position at pre- and post-intervention was used to derive linear (SDNN, RMSSD, pNN50, LF, HF, LF/HF) and non-linear (SD1, SD2, Alpha1, Alpha2, SampEn) heart rate variability (HRV) indices as measures of CAF. Group×time interaction effects were examined (ANCOVA) and Eta squared (η2) interaction effect sizes calculated. Results: While there were no significant between-group differences in CAF indices, there were small-to-medium group×time interaction effects on SDNN [F(2,52)=0.70, p=0.50, η2 =0.02], RMSSD [F(2,52)=1.35, p=0.27, η2 =0.03], HF power [F(2,52)=1.27, p=0.29, η2 =0.03], SD1 [F(2,52)=0.47, p=0.63, η2 =0.01], and SD2 [F(2,52)=0.41, p=0.67, η2 =0.01]. The following represent the relative percentage increases across these variables for 4HIIT, MICT, and 1HIIT respectively (SDNN, +30%, +17%, 9%; RMSSD, +30%, +22%, -2%; HF power, +69%, +18%, +7%; SD1, +30%, +22%,-2%; SD2, +22%, +14%, 4%). Conclusions: There were no significant between-group differences for the effects of exercise dose on CAF indices, however; high-volume HIIT demonstrated the greatest magnitude of effect for improving CAF in individuals with MetS. © 2017 Elsevier Ireland Ltd.

- Description: BACKGROUND: High-intensity interval training (HIIT) is superior to moderate-intensity continuous training (MICT) at improving cardiometabolic risk. However, the optimal volume of HIIT to reduce the severity of the metabolic syndrome (MetS) has yet to be investigated. The aim of this study was to examine the impact of different volumes of HIIT and MICT on MetS severity (MetS z-score). METHODS: This was a substudy of the "Exercise in prevention of Metabolic Syndrome" (EX-MET) multicenter trial, reporting data collected at the Brisbane site. Ninety-nine adults diagnosed with MetS were randomized to one of the following 16-week interventions: (1) MICT [n = 34, 30 min at 60%-70% heart rate (HR) peak/session, 150 min/week]; (2) 4HIIT (n = 34, 4 × 4 min bouts at 85%-95% HR peak, interspersed with 3 min active recovery at 50%-70% HR peak, 114 min/week); or (3) 1HIIT (n = 31, 1 × 4 min bout at 85%-95% HR peak, 51 min/week). Z-scores were derived from levels of MetS risk factors before and after the intervention. RESULTS: Eighty-one participants completed post-testing (MICT, n = 26; 4HIIT, n = 28, 1HIIT, n = 27). After excluding 16 participants who had a change in medication dosage or type during the intervention, a total of 65 participants were included in the analysis [MICT, n = 22, age 55 ± 10 years, body mass index (BMI) 32 ± 6 kg/m; 4HIIT, n = 22, 56 ± 10 years, 35 ± 9 kg/m2; 1HIIT, n = 21, 57 ± 8 years, 32 ± 5 kg/m). MetS severity reduced following all interventions (pre- to post-MetS z-score: MICT, 1.80 ± 1.93 to 0.90 ± 1.93; 4HIIT, 2.75 ± 2.56 to 2.17 ± 2.71; 1HIIT, 2.48 ± 3.38 to 0.84 ± 2.98), with no significant differences between groups. There were no reported adverse events that were directly related to the exercise interventions. CONCLUSIONS: Low-volume HIIT (51 min/week) was as effective as high-volume HIIT (114 min/week) and MICT (150 min/week) in ameliorating MetS severity.

- Description: Diarrhoeal diseases are among the leading causes of morbidity and mortality in the Western Pacific Region. However, data on the major causes of infectious diarrhoea are limited in many countries within the Region, including Papua New Guinea. In 2013-2014, we conducted surveillance for acute diarrhoeal illness in four provinces in Papua New Guinea. One rural health clinic from each province participated in the surveillance activity. Samples were sent to central laboratories and batch analysed for bacterial and viral gastrointestinal pathogens that are commonly associated with diarrhoea. Across the four sites, the most commonly detected pathogens were Shigella spp., Campylobacter spp. and rotavirus. In this paper, we report the results of the surveillance activity and the challenges that we faced. The lessons learnt may be applicable to other parts of the Region with a similar socioeconomic status.

- Description: Collision detection is fundamental to many kinds of simulation. Any simulation that needs to model interactions between solid objects needs some form of collision detection. However, despite this need, a general-purpose collision detection framework has not been developed for the High Level Architecture (HLA). This research paper proposes a framework which facilitates this need. The framework differs from previous solutions by conforming to the principles of low coupling and high cohesion, cornerstones of the HLA ideology, which promote reuse of simulation components. To this end, the framework does not bind itself to the existing Object Model of the simulation it supports. The HLA Data Distribution Management (DDM) services are used to increase the network and processing efficiency of the solution. By incorporation of advanced spatial partitioning and collision detection algorithms, the solution provides an accurate, fast collision detection service to HLA federates.

- Description: The Riverland Ramsar site in south-eastern Australia has Limits of Acceptable Change (LAC) derived on the basis of hydrological regimes and vegetation requirements. This study evaluated LAC for the site against trajectories of environmental change including increasing river regulation and changing climate. The study identified a high likelihood of exceedances of the LAC from changed hydrologic regime and also from changing climate, with the combined influences increasing the likelihood of breaches. Regional climatic variations in the past call into question the concept of baseline conditions for this site and elsewhere, and suggest that management plans based on ecological variation around a point in time will be insufficient. Vulnerability assessment, adaptation enhancement, and regular reviews of site condition and regional significance are suggested components for future management of Ramsar sites.

- Description: BACKGROUND:Previous research aimed at improving injury surveillance standards has focused mainly on issues of data quality rather than upon the implementation of surveillance systems. There are numerous settings where injury surveillance is not mandatory and having a better understanding of the barriers to conducting injury surveillance would lead to improved implementation strategies. One such setting is community sport, where a lack of available epidemiological data has impaired efforts to reduce injury. This study aimed to i) evaluate use of an injury surveillance system following delivery of an implementation strategy; and ii) investigate factors influencing the implementation of the system in community sports clubs. METHODS:A total of 78 clubs were targeted for implementation of an online injury surveillance system (approximately 4000 athletes) in five community Australian football leagues concurrently enrolled in a pragmatic trial of an injury prevention program called FootyFirst. System implementation was evaluated quantitatively, using the RE-AIM framework, and qualitatively, via semi-structured interviews with targeted-users. RESULTS:Across the 78 clubs, there was 69% reach, 44% adoption, 23% implementation and 9% maintenance. Reach and adoption were highest in those leagues receiving concurrent support for the delivery of FootyFirst. Targeted-users identified several barriers and facilitators to implementation including personal (e.g. belief in the importance of injury surveillance), socio-contextual (e.g. understaffing and athlete underreporting) and systems factors (e.g. the time taken to upload injury data into the online system). CONCLUSIONS:The injury surveillance system was implemented and maintained by a small proportion of clubs. Outcomes were best in those leagues receiving concurrent support for the delivery of FootyFirst, suggesting that engagement with personnel at all levels can enhance uptake of surveillance systems. Interview findings suggest that increased uptake could also be achieved by educating club personnel on the importance of recording injuries, developing clearer injury surveillance guidelines, increasing club staffing and better remunerating those who conduct surveillance, as well as offering flexible surveillance systems in a range of accessible formats. By increasing the usage of surveillance systems, data will better represent the target population and increase our understanding of the injury problem, and how to prevent it, in specific settings.

- Description: Regulation has profoundly altered the ecological character of many rivers in the world, with pronounced effects in dryland systems subject to competing demand for water between the environment and society. Pervasive changes to flow regimes have cascading effects on ecological processes and biota attuned to natural variability. The Lower River Murray in south-eastern Australia occupies a curious landscape, being a large lowland river flowing through semi-arid environs fed by a vast inland basin from upstream temperate (River Murray, seasonally predictable) and subtropical-to-desert (Darling River, episodic and highly variable) regions. Extensive regulation via upland dams, water abstraction and serial lowland weirs has reduced mean annual discharge to the sea by two-thirds and transformed riverine hydraulics, leading to dramatic changes in the composition and abundance of biota, including the simplification of a formerly biologically and functionally diverse fish assemblage. Research since the 1980s, often led by the late Keith Forbes Walker, has sought to characterise ecological response to regulation on the Lower River Murray to understand pattern and process and aid in rehabilitation. This paper synthesises a significant body of work relating to freshwater fishes in the river to set a foundation for future monitoring, research and management. © 2017 Royal Society of South Australia.

- Description: The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced species are likely to pose an elevated risk of impact to native species and ecosystems. To inform policy, stakeholders and management decisions on global threats to aquatic ecosystems, 195 assessors representing 120 risk assessment areas across all six inhabited continents screened 819 non-native species from 15 groups of aquatic organisms (freshwater, brackish, marine plants and animals) using the Aquatic Species Invasiveness Screening Kit. This multi-lingual decision-support tool for the risk screening of aquatic organisms provides assessors with risk scores for a species under current and future climate change conditions that, following a statistically based calibration, permits the accurate classification of species into high-, medium- and low-risk categories under current and predicted climate conditions. The 1730 screenings undertaken encompassed wide geographical areas (regions, political entities, parts thereof, water bodies, river basins, lake drainage basins, and marine regions), which permitted thresholds to be identified for almost all aquatic organismal groups screened as well as for tropical, temperate and continental climate classes, and for tropical and temperate marine ecoregions. In total, 33 species were identified as posing a ‘very high risk’ of being or becoming invasive, and the scores of several of these species under current climate increased under future climate conditions, primarily due to their wide thermal tolerances. The risk thresholds determined for taxonomic groups and climate zones provide a basis against which area-specific or climate-based calibrated thresholds may be interpreted. In turn, the risk rankings help decision-makers identify which species require an immediate ‘rapid’ management action (e.g. eradication, control) to avoid or mitigate adverse impacts, which require a full risk assessment, and which are to be restricted or banned with regard to importation and/or sale as ornamental or aquarium/fishery enhancement. © 2021 The Authors. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Lance Lloyd" is provided in this record**

- Description: Background Typhoid fever, a systemic infection caused by Salmonella enterica serovar Typhi, remains a considerable public health threat in impoverished regions within many low-and middle-income settings. However, we still lack a detailed understanding of the emergence, population structure, molecular mechanisms of antimicrobial resistance (AMR), and transmission dynamics of S. Typhi across many settings, particularly throughout the Asia-Pacific islands. Here we present a comprehensive whole genome sequence (WGS) based overview of S. Typhi populations circulating in Papua New Guinea (PNG) over 30 years. Principle findings Bioinformatic analysis of 86 S. Typhi isolates collected between 1980–2010 demonstrated that the population structure of PNG is dominated by a single genotype (2.1.7) that appears to have emerged in the Indonesian archipelago in the mid-twentieth century with minimal evidence of inter-country transmission. Genotypic and phenotypic data demonstrated that the PNG S. Typhi population appears to be susceptible to former first line drugs for treating typhoid fever (chloramphenicol, ampicillin and co-trimoxazole), as well as fluoroquinolones, third generation cephalosporins, and macrolides. PNG genotype 2.1.7 was genetically con-served, with very few deletions, and no evidence of plasmid or prophage acquisition. Genetic variation among this population was attributed to either single point mutations, or homologous recombination adjacent to repetitive ribosomal RNA operons. Significance Antimicrobials remain an effective option for the treatment of typhoid fever in PNG, along with other intervention strategies including improvements to water, sanitation and hygiene (WaSH) related infrastructure and potentially the introduction of Vi-conjugate vaccines. However, continued genomic surveillance is warranted to monitor for the emergence of AMR within local populations, or the introduction of AMR associated genotypes of S. Typhi in this setting. © The Authors.

- Description: Herbivores alter plant biodiversity (species richness) in many of the world’s ecosystems, but the magnitude and the direction of herbivore effects on biodiversity vary widely within and among ecosystems. One current theory predicts that herbivores enhance plant biodiversity at high productivity but have the opposite effect at low productivity. Yet, empirical support for the importance of site productivity as a mediator of these herbivore impacts is equivocal. Here, we synthesize data from 252 large-herbivore exclusion studies, spanning a 20-fold range in site productivity, to test an alternative hypothesis—that herbivore-induced changes in the competitive environment determine the response of plant biodiversity to herbivory irrespective of productivity. Under this hypothesis, when herbivores reduce the abundance (biomass, cover) of dominant species (for example, because the dominant plant is palatable), additional resources become available to support new species, thereby increasing biodiversity. By contrast, if herbivores promote high dominance by increasing the abundance of herbivory-resistant, unpalatable species, then resource availability for other species decreases reducing biodiversity. We show that herbivore-induced change in dominance, independent of site productivity or precipitation (a proxy for productivity), is the best predictor of herbivore effects on biodiversity in grassland and savannah sites. Given that most herbaceous ecosystems are dominated by one or a few species, altering the competitive environment via herbivores or by other means may be an effective strategy for conserving biodiversity in grasslands and savannahs globally.

- Description: Background: Limited information exists about how best to conduct intervention implementation studies in community sport settings. Research should be directed towards understanding the context within which evidence-based injury prevention interventions are to be implemented, while continuing to build the evidencebase for the effectiveness of sports injury interventions. Objectives: To identify factors that influence the translation of evidence-based injury prevention interventions into practice in community sport, and to provide specific evidence for the effectiveness of an evidence-based exercise training programme for lower limb injury prevention in community Australian football. Setting: Community-level Australian football clubs, teams and players. Methods: An exercise-based lower limb injury prevention programme will be developed and evaluated in terms of the implementation context, infrastructure and resources needed for its effective translation into community sport. Analysis of the community sports safety policy context will be undertaken to understand the barriers and facilitators to policy development and uptake. A randomised group-clustered ecological study will be conducted to compare the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) of the intervention over 2 years. Outcome Measures: The primary outcome will be evidence-based prevention guidelines that are fully supported by a comprehensively evaluated dissemination plan. The plan will detail the support structures and add-ons necessary to ensure sustainability and subsequent national implementation. Research outcomes will include new knowledge about how sports safety policy is set, how consensus is reached among sports safety experts in the community setting and how evidence-based safety guidelines are best developed, packaged and disseminated to community sport.

- Description: Desk-based worksites are increasingly the focus of workplace health and wellbeing interventions. These interventions often utilize an educational session prior to participants engaging, yet limited studies have specifically examined the effect education has on compliance. The purpose of this study was to investigate the effect pre-intervention participant education had on the odds of compliance to a passive e-health software program designed to increase non-exercise activity thermogenesis throughout the workday. Participants in the experimental group (n=46) were exposed to multifaceted pre-intervention participant education one day prior to initiating the e-health software intervention for an eight-week study period. The control group (n=33) also received the intervention for eight weeks, however these participants received no education prior to initiation. The e-health software had a self-report progress recording function, which recorded all logged movement entries to gain frequency counts of per day usage. The experimental group logged more active days, more movements per day and was significantly more compliant to the e-health software (OR=1.87, 95% CI = 1.56-2.24). A pre-intervention participant education session, coupled with a passive e-health software program, was an effective mechanism for decreasing prolonged employee sedentary periods and increasing movement throughout the workday.

- Description: The paper addresses a problem of efficiently controlling an autonomous underwater vehicle (AUV), where its typical underactuated model is considered. Due to critical uncertainties and nonlinearities in the system caused by unavoidable external disturbances such as ocean currents when it operates, it is paramount to robustly maintain motions of the vehicle over time as expected. Therefore, it is proposed to employ the hierarchical sliding mode control technique to design the closed-loop control scheme for the device. However, exactly determining parameters of the AUV control system is impractical since its nonlinearities and external disturbances can vary those parameters over time. Thus, it is proposed to exploit neural networks to develop an adaptive learning mechanism that allows the system to learn its parameters adaptively. More importantly, stability of the AUV system controlled by the proposed approach is theoretically proved to be guaranteed by the use of the Lyapunov theory. Effectiveness of the proposed control scheme was verified by the experiments implemented in a synthetic environment, where the obtained results are highly promising. © 2021 by the authors.

- Description: We propose attributes that are needed in sophisticated agent teams capable of working to manage an evolving disaster. Such agent teams need to be dynamically formed and ca- pable of adaptive reorganization as the demands and com- plexity of the situation evolve. The agents need to have self- awareness of their own roles, responsibilities and capabilities and be aware of their relationships with others in the team. Each agent is not only empowered to act autonomously to- ward realizing their goals, agents are also able to negotiate to change roles as a situation changes, if reorganization is required or perceived to be in the team interest. The hierar- chical 'position' of an agent and the 'relationships' between agents govern the authority and obligations that an agent adopts. Such sophisticated agents might work in a collabora- tive team with people to self-organize and manage a critical incident such as a bush-¯re. We are planning to implement a team of agents to interface with a bush-¯re simulation, working with people in real time, to test our architecture.
