- Description: This paper presents the results of calculations of the wheel angles and the drive wheel speeds to ensure that the steering effect of the wheel angles and the steering effect of the speeds of the drive wheels are identical. These calculations are general insofar as the centre of curvature of the path of the centre of the vehicle can lie anywhere in the 'horizontal' plane, including within the plan view of the vehicle. These minimal turning circles at times require large wheel angles and large differences in the drive wheel speeds. When the driver selects a centre of curvature inside the rectangle defined by the wheelbase and the track, problems arise owing to the multiple solutions of the arctan function. This problem is solved so that flipping of the wheels through 180° is avoided. Similar problems can arise in the calculation of the correct wheel speed because of the ambiguity of the square root function, which has both positive and negative roots. This problem is also solved. Alternative driver interfaces are described in detail. Vehicles with cooperative redundant multiple steering systems promise safety benefits relative to vehicles with a single non-redundant steering system and environmental benefits relative to vehicles with conflicting redundant multiple steering systems. The safety benefits result from increased traction, stability and manoeuvrability (especially on hills). The environmental benefits include reduced ground damage, tyre wear and fuel wastage on turning. These vehicles would be used to best advantage as extreme off-road vehicles. The general case of vehicles described is capable of both pure rotation and pure translation in any direction, and all motion in between. This maximized manoeuvrability also makes the system ideal for vehicles operating in confined spaces, such as forklift trucks.

- Description: Introduction There is substantial evidence to support the relationship between transcription skills (handwriting and spelling) and compositional quality. For children with developmental coordination disorder, handwriting can be particularly challenging. While recent research has aimed to investigate their handwriting difficulties in more detail, the impact of transcription on their compositional quality has not previously been examined. The aim of this exploratory study was to examine compositional quality in children with developmental coordination disorder and to ascertain whether their transcription skills influence writing quality. Method Twenty-eight children with developmental coordination disorder participated in the study, with 28 typically developing age and gender matched controls. The children completed the free-writing' task from the detailed assessment of speed of handwriting tool, which was evaluated for compositional quality using the Wechsler objective language dimensions. Results The children with developmental coordination disorder performed significantly below their typically developing peers on five of the six Wechsler objective language dimensions items. They also had a higher percentage of misspelled words. Regression analyses indicated that the number of words produced per minute and the percentage of misspelled words explained 55% of the variance for compositional quality. Conclusion The handwriting difficulties so commonly reported in children with developmental coordination disorder have wider repercussions for the quality of written composition.

- Description: Unplanned hospital readmissions are the most important, preventable cost in heart failure (HF) health economics. Current professional guidelines recommend that patient self-care is an important means by which to reduce this burden. Patients with HF should be engaged in their care such as by detecting, monitoring, and managing their symptoms. A variety of educational and behavioural interventions have been designed and implemented by health care providers to encourage and support patient self-care. Meta-analyses support the use of self-care interventions to improve patient self-care and reduce hospital readmissions; however, efficacy is variable. The aim of this review was to explore methods to achieve greater clarity and consistency in the development and reporting of self-care interventions to enable ‘change agents’ to be identified. We conclude that advancement in this field requires more explicit integration and reporting on the behaviour change theories that inform the design of self-care interventions and the selection of behaviour change techniques. The systematic application of validated checklists, such as the Theory Coding Scheme and the CALO-RE taxonomy, will improve the systematic testing and refinement of interventions to enable ‘change agent/s’ to be identified and optimised.

- Description: This article elucidates grounds for engagement between two fields of the social sciences engaged in critique of Eurocentrism: contemporary civilizations analysis and postcolonial sociology. Between the two fields there are both evident dissonances and points of potential dialogue and engagement. The article identifies three areas of high contention: divergent perceptions of essentialism, commitments to transformative politics and evaluations of the paradigm of multiple modernities. Despite extensive theoretical and normative differences, a notional intersection of the two fields is outlined in the form of three conceptual and methodological shifts. The first is a displacement of ideal typology. The second move is the most original. ‘Intercivilizational encounters’ and ‘intracivilizational encounters’ are re-cast as ‘intercivilizational engagement’. The goal is the demarcation of a discrete position based on a strong version of interaction that goes further than the notion of intercivilizational encounters recently re-developed in civilizational analysis. To illustrate potential grounds for engagement on this point, the article reviews the historiography of ‘connected histories’ and the insights of relational historians. Finally, the article urges for a nuanced definition of ‘region’ and deeper appreciation of the multiplicity of regionalisms as a meeting point for both fields of critique of Eurocentrism.

- Description: It is generally accepted by historians that in the early twentieth century clubs in Australian Football's Victorian Football League (VFL) made payments to "amateur" players prior to the legalization of professionalism and that such payments were not disclosed in club financial reports. Previously, financial reports have not been used to support or refute such claims. This article presents findings from a detailed examination of the financial reports and other records of six of the 10 VFL clubs for the years surrounding the legalization of professional football in 1911 (1909-1912). Prior to 1911, most clubs engaged in fraudulent financial reporting practices by misrepresenting player payments as other forms of permitted expenditures, thus concealing prohibited remunerative payments to players within their financial reports. Using isomorphic influences to explain the reasons for this misrepresentation, we conclude that the financial reports were used to legitimate the majority of clubs as amateur organizations. Competing isomorphic pressures, particularly conflicting coercive factors related to the VFL's prohibition on player payments and normative pressures associated with increasing professionalism amongst players, contributed to clubs engaging in fraudulent financial reporting. © The Author(s) 2015.

- Description: Objective: This study explored young university students’ (aged 18–24 years) health literacy, asthma experiences and help-seeking behaviours to inform the development of a web-based asthma education intervention relevant to this age group. Design: Exploratory mixed-methods design incorporateing a health literacy survey and interviews, plus the development of a web-based educational video. Setting: Participants were students at two universities in the state of Victoria, Australia. Method: In total, 20 asthma sufferers were interviewed by trained pairs of university students. Interpretative phenomenology underpinned the narrative analysis and enabled the description of the participants’ lived experience. A branching e-simulation video was developed. Results: A number of key themes were identified: ‘Life with asthma’, including ‘A life of vigilance’ regarding asthma triggers, lifestyle limitations and heightened sensitivities; ‘Asthma management – call Mum’, a lack of knowledge and support systems with substantial maternal reliance; ‘Health literacy: family and Dr Google’, denoting low health literacy levels with passive reluctant involvement in personal health management; and ‘Information gathering – one size doesn’t fit all’ – in the form of the need for immediate gratification and resource variety. Based on interviewees’ words and terminology, we designed an interactive branching educational video for YouTube portraying a young person (an actor) during an asthma flare-up. Conclusion: Young adults lacked insight into their condition and even after moving away from home, relied on Google searches and/or parents’ advice. To enhance health-seeking behaviours, interactive programmes with smartphone access may be valuable.

- Description: Health-related data is stored in a number of repositories that are managed and controlled by different entities. For instance, Electronic Health Records are usually administered by governments. Electronic Medical Records are typically controlled by health care providers, whereas Personal Health Records are managed directly by patients. Recently, Blockchain-based health record systems largely regulated by technology have emerged as another type of repository. Repositories for storing health data differ from one another based on cost, level of security and quality of performance. Not only has the type of repositories increased in recent years, but the quantum of health data to be stored has increased. For instance, the advent of wearable sensors that capture physiological signs has resulted in an exponential growth in digital health data. The increase in the types of repository and amount of data has driven a need for intelligent processes to select appropriate repositories as data is collected. However, the storage allocation decision is complex and nuanced. The challenges are exacerbated when health data are continuously streamed, as is the case with wearable sensors. Although patients are not always solely responsible for determining which repository should be used, they typically have some input into this decision. Patients can be expected to have idiosyncratic preferences regarding storage decisions depending on their unique contexts. In this paper, we propose a predictive model for the storage of health data that can meet patient needs and make storage decisions rapidly, in real-time, even with data streaming from wearable sensors. The model is built with a machine learning classifier that learns the mapping between characteristics of health data and features of storage repositories from a training set generated synthetically from correlations evident from small samples of experts. Results from the evaluation demonstrate the viability of the machine learning technique used. © The Author(s) 2020.

- Description: This study will highlight the diagnostic potential that radar plots display for reporting on performance benchmarking from patient admissions to hospital for surgical procedures. Two drawbacks of radar plots – the presence of missing information and ordering of indicators – are addressed. Ten different orthopaedic surgery procedures were considered in this study. Moreover, twelve outcome indicators were provided for each of the 10 surgeries of interest. These indicators were displayed using a radar plot, which we call a scorecard. At the hospital level, we propose a facile process by which to consolidate our 10 scorecards into one. We addressed the ordering of indicators in our scorecards by considering the national median of the indicators as a benchmark. Furthermore, our the consolidated scorecard facilitates concise visualisation and dissemination of complex data. It also enables the classification of providers into potential low and high performers that warrant further investigation. In conclusion, radar plots provide a clear and effective comparative tool for discerning multiple outcome indicators against the benchmarks of patient admission. A case study between two top and bottom performers on a consolidated scorecard (at hospital level) showed that medical provider charges varied more than other outcome indicators. © The Author(s) 2020.

The authors detail the ethical challenges behind the development of the project, and around conducting research with a minority and vulnerable population. The article illustrates how the utilization of feminist and queer theory has impacted the process of conducting ethical research, including approaches to recruitment and participant autonomy. The dilemmas of confidentiality within a self-labelled and easily identifiable population are resolved. Further, unexpected challenges and risks to participant safety created through adherence to institutional ethical research frameworks are rectified. Importantly, the authors seek to avoid revictimization of participants and to instead empower students in their responses to violence, harassment and bullying that they may have experienced. The authors point to utilization of theoretical foundations and continual reflexive improvement as elements of best practice for those seeking to research minority populations, and in projects marked by the participation of those deemed vulnerable and high-risk. © 2016, © The Author(s) 2016.

- Description: Although Vietnam has promoted the utilisation of highly active antiretroviral therapy (HAART) towards HIV elimination targets, adherence to treatment has remained under-investigated. We aimed to describe high-risk behaviours and clinical characteristics by adherence status and to identify the factors associated with non-adherence. We included 426 people living with HIV (PLWH) currently or previously involved in HAART. Most participants were men (75.4%), young (33.6 years), with low income and low education levels. Non-adherent PLWH (11.5%) were more likely to have a larger number of sex partners (p-value = 0.053), sex without condom use (p-value = 0.007) and not receive result at hospital or voluntary test centre (p-value = 0.001). Multiple logistic regression analysis showed that demographic (education levels), sexual risk behaviours (multiple sex partners and sex without using condom) and clinical characteristics (time and facility at first time received HIV-positive result) were associated with HAART non-adherence. There are differences in associated factors between women (education levels and place of HIV testing) and men (multiple sex partners). Gender-specific programs, changing risky behaviours and reducing harms among PLWH may benefit adherence. We highlight the need to improve the quantity and quality of HIV/AIDS services in Vietnam, especially in pre- and post-test counselling, to achieve better HAART adherence, working towards ending AIDS in 2030. © The Author(s) 2021. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Huy Nguyen” is provided in this record**

- Description: This study provides a systematic review of the empirical evidence related to the association between problem gambling and intimate partner violence (IPV). We identified 14 available studies in the systematic search (8 for victimisation only, 4 for perpetration only and 2 for both victimisation and perpetration). Although there were some equivocal findings, we found that most of the available research suggests that there is a significant relationship between problem gambling and being a victim of IPV. There was more consistent evidence that there is a significant relationship between problem gambling and perpetration of IPV. Meta-analyses revealed that over one third of problem gamblers report being victims of physical IPV (38.1%) or perpetrators of physical IPV (36.5%) and that the prevalence of problem gambling in IPV perpetrators is 11.3%. Although the exact nature of the relationships between problem gambling and IPV is yet to be determined, the findings suggest that less than full employment and clinical anger problems are implicated in the relationship between problem gambling and IPV victimization and that younger age, less than full employment, clinical anger problems, impulsivity, and alcohol and substance use are implicated in the relationship between problem gambling and IPV perpetration. The findings highlight the need for treatment services to undertake routine screening and assessment of problem gambling, IPV, alcohol and substance use problems, and mental health issues and provide interventions designed to manage this cluster of comorbid conditions. Further research is also required to investigate the relationship between problem gambling and violence that extends into the family beyond intimate partners. © 2014, The Author(s) 2014. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Shane Thomas” is provided in this record**

- Description: This study examines the influence of perceived organisational support (POS) on expatriates’ cross-cultural adjustment, assignment completion and job satisfaction in the sub-Saharan African context. While multinationals depend on expatriates to manage their foreign subsidiaries, successful expatriation is influenced by expatriates’ cross-cultural adjustment to their host country’s environment. Survey responses from 229 expatriates were analysed using partial least squares path modelling. The results reveal that support from their organisations relates positively to expatriate adjustment, assignment completion and job satisfaction. The empirical results also demonstrate that expatriate adjustment partially mediates the relationship between POS and assignment completion and job satisfaction. Furthermore, findings suggest that assignment completion positively influences job satisfaction and partially mediates the association between POS and job satisfaction. The findings of this research have important theoretical and practical implications for multinational companies operating in sub-Saharan Africa. © The Author(s) 2021.

- Description: Feeling and expressing love is at the core of romantic relationships, but individuals differ in their proclivity to worry about their relationships and/or avoid intimacy. Saying “I love you” signals a commitment to a future with our romantic partner. Contrary to gender stereotypes, research in the United States demonstrates that men are more likely to confess love first. We aimed to replicate this sex difference in an online cross-national sample (seven countries, three continents), while testing for variation according to attachment style and environment (the national sex ratio). Men were more likely to confess love first in a relationship, with preliminary evidence that this was more likely when men had more choice (more female-biased sex ratio). Independent of biological sex, highly avoidant respondents were less happy to hear “I love you” than less avoidant respondents, and highly anxious respondents were happier to hear “I love you” than less anxious respondents. Our findings suggest that prior observations generalize beyond an ethnically homogenous sample and incorporate attachment theory into the study of love confessions. Our research suggests a dissociation between initial declarations of love (moderated by biological sex) and emotional responses to love confessions, moderated by attachment style but not by biological sex. © The Author(s) 2022.

- Description: This article discusses the use of the Most Significant Change (MSC) technique in a mixed-methods evaluation of a pilot wellbeing programme for obstetrics and gynaecology doctors-in-training introduced at a large public hospital during Melbourne, Australia’s second coronavirus (COVID-19) lockdown, which occurred from 7 July to 26 October 2020. The evaluation was conducted remotely using videoconferencing technology, to conform with pandemic restrictions. MSC complemented the program’s participatory principles and was chosen because it seeks to learn about participants’ perceptions of programme impacts by evaluating their stories of significant change. Stakeholders select one story exemplifying the most significant change resulting from the evaluated program. Inductive thematic analysis of all stories is combined with reasons for making the selection, to inform learnings (Dart & Davies, 2003; Tonkin et al., 2021). Nine stories of change were included in the selection. The most significant change was a more supportive workplace culture brought about by enabling basic needs to be met and breaking down hierarchical barriers. This was linked to five interconnected themes – connection, caring, communication, confidence and cooperation. The evaluation learnings are explored and reflections on remotely conducting MSC evaluation are shared. © The Author(s) 2022.

- Description: Vehicular cloud computing is envisioned to deliver services that provide traffic safety and efficiency to vehicles. Vehicular cloud computing has great potential to change the contemporary vehicular communication paradigm. Explicitly, the underutilized resources of vehicles can be shared with other vehicles to manage traffic during congestion. These resources include but are not limited to storage, computing power, and Internet connectivity. This study reviews current traffic management systems to analyze the role and significance of vehicular cloud computing in road traffic management. First, an abstraction of the vehicular cloud infrastructure in an urban scenario is presented to explore the vehicular cloud computing process. A taxonomy of vehicular clouds that defines the cloud formation, integration types, and services is presented. A taxonomy of vehicular cloud services is also provided to explore the object types involved and their positions within the vehicular cloud. A comparison of the current state-of-the-art traffic management systems is performed in terms of parameters, such as vehicular ad hoc network infrastructure, Internet dependency, cloud management, scalability, traffic flow control, and emerging services. Potential future challenges and emerging technologies, such as the Internet of vehicles and its incorporation in traffic congestion control, are also discussed. Vehicular cloud computing is envisioned to have a substantial role in the development of smart traffic management solutions and in emerging Internet of vehicles. © The Author(s) 2017.

- Description: This essay aims to examine metropolitan cities of Latin America with two aspects of the literature in anthropology, history, and sociology in mind. First, the essay addresses an imbalanced focus on cities in the USA and Canada by sketching the significance of migration, creation, and urban development in four major metropolises of Latin America. Second, in place of a framework of urban imaginaries, which has dominated the sociology of Latin American cities in recent years, I argue for a more precise notion of metropolitan imaginaries that better frames the creativity of particular cities and their level of integration into international and regional networks. With this more precise notion, I distinguish southern cities as highly connected places, which attract migrants and bring economic and cultural traffic to their shores, ports, plazas, and streets. They are lively centers of Atlantic modernity with connections that generate greater magnitude for creativity and, as such, bear international significance as places of architecture and urban design. In their informal settlements, impulses of organic creation further distinguish southern metropolises from their North American counterparts. The quality of international and regional connections distinguishes these cities from other urban centers in Latin America, a point underestimated in the literature on urban imaginaries. In this essay, I examine 19th and 20th-century Buenos Aires, Mexico City, São Paulo, and Rio de Janeiro. Each is distinguished from most cities by the magnitude of migration, the diversity of their populations, and the connections they have to global and regional developments. Crucially, each one stands out for the quality and impact of their metropolis-making, particularly in creative architecture and urban design. © The Author(s) 2021.

- Description: Background: The anti-DFS70 autoantibodies are one of the most commonly and widely described agent of unknown clinical significance, frequently detected in healthy individuals. It is not known whether the DFS70 autoantibodies are protective or pathogenic. One of the factors suspected of inducing the formation of anti-DFS70 antibodies is increased oxidative stress. We evaluated the coexistence of anti-DFS70 antibodies with selected markers of oxidative stress and investigated whether these antibodies could be considered as indirect markers of oxidative stress. Methods: The intensity of oxidative stress was measured in all samples via indices of free-radical damage to lipids and proteins such as total oxidant status (TOS), concentrations of lipid hydroperoxides (LPH), lipofuscin (LPS), and malondialdehyde (MDA). The parameters of the non-enzymatic antioxidant system, such as total antioxidant status (TAS) and uric acid concentration (UA), were also measured, as well as the activity of superoxide dismutase (SOD). Based on TOS and TAS values, the oxidative stress index (OSI) was calculated. All samples were also tested with indirect immunofluorescence assay (IFA) and 357 samples were selected for direct monospecific anti DFS70 enzyme-linked immunosorbent assay (ELISA) testing. Results: The anti-DFS70 antibodies were confirmed by ELISA test in 21.29% of samples. Compared with anti-DFS70 negative samples we observed 23% lower concentration of LPH (P =.038) and 11% lower concentration of UA (P =.005). TOS was 20% lower (P =.014). The activity of SOD was up to 5% higher (P =.037). The Pearson correlation showed weak negative correlation for LPH, UA, and TOS and a weak positive correlation for SOD activity. Conclusion: In samples positive for the anti-DFS70 antibody a decreased level of oxidative stress was observed, especially in the case of samples with a high antibody titer. Anti-DFS70 antibodies can be considered as an indirect marker of reduced oxidative stress or a marker indicating the recent intensification of antioxidant processes. © The Author(s) 2022. **Please note that there are multiple authors for this article therefore only the name of the first 30 including Federation University Australia affiliate “Fadi Charchar” is provided in this record**

- Description: Classical musicians are under constant pressure to perform at near perfect levels, and are highly vulnerable to the negative effects of music performance anxiety. This study aimed to examine the mechanisms by which two types of perfectionism (personal standards and evaluative concerns) relate to music performance anxiety, and to explore the moderating roles of active and avoidant coping on the relationship between these perfectionism types and music performance anxiety. A sample of 118 classical performing musicians (35 males, 82 females, 1 other; Mage = 42.00, SD = 14.68) were recruited to participate in an anonymous online questionnaire assessing music performance anxiety, coping and perfectionism. Results indicated that the two dimensions of perfectionism were positively associated with music performance anxiety. Personal standards perfectionism was associated with active coping, and evaluative concerns perfectionism with avoidant coping. Active coping moderated the relationship between personal standards perfectionism and performance anxiety, but only at high and medium levels. Contrary to the prediction, avoidant coping did not moderate the relationship between evaluative concerns perfectionism and performance anxiety.

- Description: Classical musicians are under constant pressure to perform at near perfect levels, and are highly vulnerable to the negative effects of music performance anxiety. This study aimed to examine the mechanisms by which two types of perfectionism (personal standards and evaluative concerns) relate to music performance anxiety, and to explore the moderating roles of active and avoidant coping on the relationship between these perfectionism types and music performance anxiety. A sample of 118 classical performing musicians (35 males, 82 females, 1 other; Mage = 42.00, SD = 14.68) were recruited to participate in an anonymous online questionnaire assessing music performance anxiety, coping and perfectionism. Results indicated that the two dimensions of perfectionism were positively associated with music performance anxiety. Personal standards perfectionism was associated with active coping, and evaluative concerns perfectionism with avoidant coping. Active coping moderated the relationship between personal standards perfectionism and performance anxiety, but only at high and medium levels. Contrary to the prediction, avoidant coping did not moderate the relationship between evaluative concerns perfectionism and performance anxiety. These findings highlight key relationships between music performance anxiety and the interaction of personal standards perfectionism and active coping. © The Author(s) 2022.
