Abstract: In February 2018 the Remote Medical Practitioner (RMP)‐led telehealth model for providing both primary care advice and aeromedical retrievals in Central Australia was replaced by the Medical Retrieval and Consultation Centre (MRaCC) and Remote Outreach Consultation Centre (ROCC). In this new model, specialists with advanced critical care skills provide telehealth consultations for emergencies 24/7 and afterhours primary care advice (MRaCC) while RMPs (general practitioners) provide primary care telehealth advice in business hours via the separate ROCC. To evaluate changes in clinicians’ perceptions of efficiency and timeliness of the new (MRaCC) and (ROCC) model in Central Australia. There were 103 and 72 respondents, respectively, to pre‐ and post‐implementation surveys of remote clinicians and specialist staff. Both emergency and primary care aspects of telehealth support were perceived as being significantly more timely and efficient under the newly introduced MRaCC/ROCC model. Importantly, health professionals in remote community were more likely to feel that their access to clinical support during emergencies was consistent and immediately available. Respondents consistently perceived the new MRaCC/ROCC model more favourably than the previous RMP‐led model, suggesting that there are benefits to having separate referral streams for telehealth advice for primary health care and emergencies, and staffing the emergency stream with specialists with advanced critical care skills. Given the paucity of literature about optimal models for providing pre‐hospital medical care to remote residents, the findings have substantial local, national and international relevance and implications, particularly in similar geographically large countries, with low population density.

Abstract: The purpose of this paper is to improve the understanding of the factors influencing the success of digital transformation (DT) and problems/challenges in DT as well as the communication methods used to involve citizens, based on a systematic literature review of research articles about citizen involvement in DT published between January 2010 and May 2021. After establishing inclusion and exclusion criteria, a systematic review of relevant studies was conducted. Out of a total of 547 articles, 33 met the paper selection criteria. The analysis of the included 33 empirical studies reveals that the factors influencing the success of DT can be described as the opposite side from challenges and problems in DT. These factors and challenges roblems all influence DT and they can be grouped into organisational values, management capabilities, organisational infrastructure, and workforce capabilities. The communication methods for citizen involvement in DT include: (1) communication mediated by human, (2) communication mediated by computers, and (3) mixed communication methods. The study identified specific factors that influence DT supported by citizen involvement, at a more fine-grained level. The findings concerning communication methods extend related studies for citizen involvement by adding town hall meetings and communication methods mediated by computers. Furthermore, this study links the research findings to develop a framework for citizen involvement in DT, assisting in better selecting communication methods to involve citizens for addressing problem areas in DT.

Abstract: Artificial Intelligence has found applications in a wide range of fields, including conversational agents designed for healthcare services. The quality of healthcare services greatly depends on the quality of the information provided by the agents. Achieving quality-assured information from conversational agents to support effective decision-making remains as a significant challenge in healthcare. Although prior review studies have shown an interest in investigating the information quality (IQ) of conversational agents in healthcare, no systematic review has been performed to present IQ definitions, factors influencing IQ, and IQ impacts. We conducted a systematic review of 45 articles published up to 2021 to investigate IQ definitions, factors influencing IQ, and IQ impacts in the context of conversational agents applied in healthcare. The findings of this review are integrated into a conceptual framework for the IQ research program in the context of conversational agents in healthcare, which has not been received attention in the literature, guiding future research directions. The present study also discusses implications for both researchers and practitioners to enhance the agents’ IQ and improve the quality of health-related services.

Abstract: Adult learning is a lifelong process whereby knowledge is formed through the transformation of adults' experience. Research on online adult learning has been on the rise in recent years, thanks to the innovative opportunities provided to adults by digital technologies. Online communities of practice (OCOPs) a one of such opportunities, which offer the potential to bring geographically dispersed adult learners together through a common interest. Despite an increased growth in the use of OCOPs by adults in various professional sectors, there is still a lack of understanding of the characteristics of online adult learning in OCOPs, and the facilitators and hinderers influencing engagement in these communities. This paper presents a comprehensive synthesis of research literature on online adult learning in OCOPs to understand its characteristics and what may facilitate or hinder adults' engagement in these communities. A review has been conducted using a systematic, rigorous and standard procedure, aiming to summarise and synthesise existing research on the topic and to provide analytical criticism. In total, thirty‐seven studies were included in this review. Findings revealed that members of OCOPs are independent, experience‐centred, problem‐centred, self‐motivated, goal‐oriented, and lifelong learners with the purpose to achieve professional outcomes. Moreover, the results revealed how the engagement of adults in OCOPs could lead to improving learning processes. Findings also showed that the level of engagement is influenced by aging, fatigue caused by a busy life, resistance process due to learning new technologies, lack of personal evolution, interactive learning settings, motivation, self‐regulation and competition factors. This study revealed facilitators and hinderers of engagement in OCOPs. The study extended andragogy to digital environments and contributes to the theory by making sense of characteristic of adult learning in OCOPs. What is already known about this topic The importance of lifelong learning for adults in the digital era has been stressed by past studies. Digital technologies have offered new opportunities for professional adults to continuously develop their skills and knowledge. Online communities of practice can facilitate self‐directed and in idual‐centred learning. What this paper adds Enhances our understanding of online adult learners as lifelong learners taking advantage of OCOPs for professional and personal development. Provides a systematic literature review (SLR) of recent studies on online adult learners' characteristics. Presents facilitators and hinderers of adults' engagement in OCOPs. Makes recommendations on future research and practice into lifelong learning in the digital era. Implications for practice and/or policy There is a need to reframe the way lifelong learning via OCOPs is defined, to account for adults' needs more effectively, where in iduals are better engaged to share their experiences that are valuable to them and connects them with their peers to build sustainable online communities.

Abstract: Adult learning is a complex phenomenon that takes place over an adult’s lifetime and is not limited to a particular age. It includes a set of activities to enhance life through improving skills, knowledge and capabilities. The foundational theories of adult learning, such as andragogy theory, place the in idual adult centre stage and differentiate adult learning from formal learning. They also shift the focus from the in iduals to the environment in which adult learning takes place. In line with this movement, online communities of practice (OCOPs) have evolved from being considered as online environments for learning to specialised forums that allow practitioners to collaborate around a project of mutual interest. The principles of adult learning are directly applicable to engagement in OCOPs because they include practical methods founded on the belief that adults are self-directed, autonomous learners and that learning is most effective when the environment plays the role of a facilitator, rather than being just a supportive and traditional setting for learning. However, how in idual adults engage in OCOPs and benefit from them is not well understood. This paper draws on social cognitive theory to examine: how environmental, personal and behavioural factors shape engagement in OCOPs. To answer this question, twenty-one interviews were conducted with members of GitHub, a large online community of practice for IT professionals. The findings revealed that adults’ engagement in OCOPs involves project-based activities on mutual interests and willingness to help others. The findings also show that engaging in online communities does not only satisfy intrinsic, well-defined, expected outcomes and shape adults’ engagement, but also has an impact on adults’ lifelong learning achievements, such as professional experience and credit recognition. Based on these findings, a revised framework for adults’ engagement in OCOPs is presented and discussed.

Abstract: Communities around the world adapt to warming climates in a number of ways. Adaptations can often be energy intensive or dependent on expensive infrastructure to cope with harsh weather, so the use of renewable energy and energy efficient housing is becoming an increasing feature in conversations about climate change adaptation. The cost of energy for households continues to increase, with this cost adding considerable financial pressure on low-income households in both developed and developing countries. The concept of ‘energy poverty’ is gaining utility around the world to highlight the prevalent dilemma faced by low-income households that they cannot afford the level of energy use to maintain their desired livelihood. In regions of the world with extended periods of extreme weather, households can allocate as much as 20 per cent of their budget on energy consumption to maintain comfortable housing. Research by the authors indicates that effective adaptation must not add to the financial burden on low-income households, if the liveability of Australia’s semi-arid region is to be sustained.

Abstract: The agriculture sector in northern Australia is vulnerable to the impacts of climate change and climate variability. Climate change risks for future agricultural development include higher atmospheric temperature, increased rainfall variability and an increase in the frequency and severity of extreme weather events such as floods, droughts, heatwaves and fires. An uncertain future climate can affect agricultural production, efficient resource use and sustainable livelihoods. A balance needs to be achieved between resource use and livelihood security for sustainable agricultural development amid stressors such as climate change. This paper examines sustainable agricultural development in northern Australia using the environmental livelihood framework, a new approach that explores the relationships between water, energy and food resources and the livelihoods they sustain. The study shows that developments in the renewable energy sector, water infrastructure sector and advances in research and development for climate resilient infrastructure and climate resilient species are likely to improve agricultural production in northern Australia. Measures to attract and retain agricultural workforce is also key to maintaining a sustainable agricultural workforce in northern Australia. Adequate monitoring and evaluation of agricultural investments is important as future climatic impacts remain uncertain.

Abstract: This scoping review explores the structure and process‐level strategies that are associated with medical retrieval outcomes. A secondary aim is to identify the range of medical retrieval outcomes used to assess the performance of remote retrieval services. A scoping review of peer‐reviewed literature from PubMed, CINAHL and the Web of Science was undertaken following guidelines set by the Johanna Briggs Institute manual for scoping reviews. All articles were assessed by two reviewers. Themes were derived inductively from the data extracted. Medical retrievals in sparsely populated remote locations in high‐income countries. Staff and clients of remote medical retrieval services. Structures and processes (e.g. resource availability, retrieval staff structures and governance protocols) that aimed to improve medical retrieval outcomes. Patient health outcomes and service efficiency. Twenty‐four articles were included. Three broad themes, related to the nature of the interventions, were included: optimising prehospital management of retrievals, staffing and resourcing of retrieval services and retrieval model evaluation. Mortality was the most frequently used outcome indicator in these studies, but was not measured consistently across studies. This review highlights significant gaps in the literature that describes the structure and processes of retrieval models operating in remote areas and a dearth of literature evaluating specific operational strategies implemented within medical retrieval models. The available literature does not meaningfully assist with identifying key outcome indicators for developing a consistent monitoring and evaluation framework for retrieval services in geographically, culturally and demographically erse remote contexts.

Abstract: This study tested whether the effects of a short period of nutritional supplementation given to ewes during the luteal phase on follicle development and ovulation rate is associated with an increase in circulating concentrations of FSH, glucose or metabolic hormones. Oestrus was synchronised with two prostaglandin injections given 9 days apart and the supplement consisted of corn grain and soybean meal. Corriedale ewes with low body condition were randomly assigned to 2 groups: the control group (C n = 10) received a maintenance diet while the short-term supplemented group (STS n = 10) received double the maintenance diet over days 9 to 14 of the oestrous cycle (day 0 = ovulation). Ovaries were examined daily by ultrasound and blood was s led three times a day during the inter-ovulatory interval for measuring reproductive and metabolic hormones. On days 9, 11 and 14 of the oestrous cycle, half of the ewes from each group ( n = 5) were bled intensively to determine the concentrations of glucose, insulin, IGF-I and leptin. Plasma FSH, progesterone, oestradiol and androstenedione concentrations were similar among groups. Dietary supplementation increased plasma insulin concentrations from the first to the sixth day of supplementation and increased glucose concentrations on the third day, compared with control ewes. Plasma leptin concentrations were higher in STS ewes from the second to the fifth day of supplementation. The pattern of IGF-I concentrations was similar among groups. In STS ewes, the nutritional treatment prolonged the lifespan of the last non-ovulatory follicle, so fewer follicular waves developed during the cycle. In STS ewes, increased concentrations of glucose, insulin and leptin one day before ovulatory wave emergence were associated with increased numbers of follicles growing from 2 to 3 mm and with stimulation of the dominant follicle to grow for a longer period. We suggest that the mechanism by which short-term nutritional supplementation affects follicle development does not involve an increase in FSH concentrations, but may involve responses to increased concentrations of glucose, insulin and leptin, acting directly at the ovarian level. This effect is acute, since concentrations of all three substances decrease after reaching peak values on the third day of supplementation. The status of follicle development at the time of maximum concentrations of glucose and metabolic hormones may be one of the factors that determines whether ovulation rate increases or not.

Abstract: Quantifying the potential costs of catastrophic and climate impacted hazards is a challenging but important exercise as the occurrence of such events is usually associated with high damage and uncertainty. At the local level, there is often a lack of information on rare extreme events, which means that the available data is not sufficient to fit a distribution and derive parameter values for frequency and severity distributions. This paper discusses the use of local assessments of extreme events and utilises expert elicitation in order to obtain values for distribution parameters that will feed into management decisions with regards to quantifying catastrophic risks. We illustrate a simple approach, where a local expert is required to only specify two percentiles of the loss distribution in order to provide an estimate for the severity distribution of climate impacted hazards. In our approach we use heavy-tailed distributions to capture the severity of events. Our method allows local government decision makers to focus on extreme losses and the tail of the distribution. An illustration of the method is provided utilising an ex le that quantifies property losses from bushfires for a local area in northern Sydney. We further illustrate how key variables, such as discount rates, assumptions about climatic change and adaptation measures, will impact the estimates of losses.

Abstract: Access to high-quality primary healthcare is limited for remote residents in Australia. Increasingly, remote health services are reliant on short-term or ‘fly-in, fly-out/drive-in, drive-out’ health workforce to deliver primary healthcare. A key strategy to achieving health service access equity, particularly evident in remote Australia, has been the development of Aboriginal Community Controlled Health Services (ACCHSs). This study aims to generate new knowledge about (1) the impact of short-term staffing in remote and rural ACCHSs on Aboriginal and Torres Strait Islander communities (2) the potential mitigating effect of community control and (3) effective, context-specific evidence-based retention strategies. This paper describes a 3-year, mixed methods study involving 12 ACCHSs across three states. The methods are situated within an evidence-based programme logic framework for rural and remote primary healthcare services. Quantitative data will be used to describe staffing stability and turnover, with multiple regression analyses to determine associations between independent variables (population size, geographical remoteness, resident staff turnover and socioeconomic status) and dependent variables related to patient care, service cost, quality and effectiveness. Qualitative assessment will include interviews and focus groups with clinical staff, clinic users, regionally-based retrieval staff and representatives of jurisdictional peak bodies for the ACCHS sector, to understand the impact of short-term staff on quality and continuity of patient care, as well as satisfaction and acceptability of services. The study has ethics approval from the Human Research Ethics Committee of the Northern Territory Department of Health and Menzies School of Health Research (project number DR03171), Central Australian Human Research Ethics Committee (CA-19-3493), Western Australian Aboriginal Health Ethics Committee (WAAHEC-938) and Far North Queensland Human Research Ethics Committee (HREC/2019/QCH/56393). Results will be disseminated through peer-reviewed journals, the project steering committee and community/stakeholder engagement activities to be determined by each ACCHS.
