- Abstract
Current government policy in Victoria, as elsewhere, is seeking to change the provision of maternity care from an obstetric-led system to a flatter, more collaborative system that brings midwives to the front line as primary carers, at least in the public sector. However, dominant medical discourses continue to exert a sedimentary effect on contesting claims from midwives that deny the high-risk nature of the majority of births and which valorise the competence of the female body. Although there have been modifications in maternity arrangements (and the incumbent government is currently considering more), medical discourses continue to legitimate obstetric power via legal and professional structures, fortify the obstetric ‘habitus’, infect mainstream popular consciousness and undermine autonomous midwifery practice. Drawing from research material gleaned from in-depth interviews with nine obstetricians and thirty midwives conducted in 2004 and 2005, I argue that alternative discourses may strategically undermine obstetric dominance. Specifically, reversing stereotypes; inverting the binary opposition and privileging the subordinate term (or substituting the negative for positive); and defamiliarizing what is perceived to be fixed and given, all play on the ambiguities of representation and present social activists (midwives, childbirth educators and women) with valuable opportunities to challenge fundamentalist medical orthodoxies.

- Abstract
The increasing use of online technologies, including ‘virtual worlds’ such as Second Life, provides sociology with a transformed context within which to ply creative research approaches to ongoing social issues, such as the ‘bystander effect’. While the ‘bystander effect’ was coined following a real-life incident, the concept has been researched primarily through laboratory-based experiments. The relationship between ‘virtual’ and ‘real’ world environments and human behaviours are, however, unclear and warrant careful attention and research. In this paper we outline existing literature on the applicability of computer-simulated activity to real world contexts. We consider the potential of Second Life as a research environment in which ‘virtual’ and ‘real’ human responses are potentially more blurred than in real-life or a laboratory setting. We describe preliminary research in which unsolicited Second Life participants faced a situation in which they could have intervened. Our findings suggest the existence of a common perception that formal regulators were close at hand, and that this contributed to the hesitation of some people to personally intervene in the fraught situation. In addition to providing another angle on the ‘bystander effect’, this research contributes to our understanding of how new technologies might enable us to conduct social research in creative ways.

- Abstract
Youth and risk are artefacts of expertise, constructed at the intersection of a wide range of knowledges about Youth and so-called Youth issues: an intersection marked by institutionalised, scientific representations of education, family, the life course, risk, and so on. In this paper I suggest that the messiness of human experiences and existence requires knowledge practices in the social sciences that can rethink what counts as truth. These interests – which are grounded in the knowledge practices that frame the work being undertaken in a large scale, qualitative investigation of the cultural drivers shaping the alcohol practices of 14 to 24 year old Australian’s - will be addressed through a discussion of the ways in which Tim Winton’s (2008) new novel Breath can be read as an allegorical tale about the terror of being ordinary: and of the teenage years as being a time in a life in which the fear of being ordinary compels Winton’s key characters to seek out, sometimes stumble upon, and embrace that which promises to make their’s a life less ordinary. In these recollections risk is something that breathes energy and purpose into lifeworlds that are dominated by the institutionalised ordinariness of family, school, and work.

The aims of the present article were the following: (i) to provide some evidence of the potential of virtual reality (VR) for the assessment, training and recovery of hemispatial neglect; (ii) to present data from our laboratory which seem to confirm that the clinical manifestation of neglect can be improved by using VR techniques; and (iii) to ascertain the neural bases of this improvement.We used a VR device (DataGlove) interfaced with a specially designed computer program which allowed neglect patients to reach and grasp a real object while simultaneously observing the grasping of a virtual object located within a virtual environment by a virtual hand. The virtual hand was commanded in real time by their real hand.After a period of training, hemispatial neglect patients coded the visual stimuli within the neglected space in an identical fashion as those presented within the preserved portions of space. However it was also found that only patients with lesions that spared the inferior parietal/superior temporal regions were able to benefit from the virtual reality training.It was concluded that using VR it is possible to re-create links between the affected and the nonaffected space in neglect patients. Furthermore, that specific regions may play a crucial role in the recovery of space that underlies the improvement of neglect patients when trained with virtual reality. The implications of these results for determining the neural bases of a higher order attentional and/or spatial representation, and for the treatment of patients with unilateral neglect are discussed.

This paper briefly summarises1 findings from a South Australian study that examined whether Judges' decisions to sentence offenders to imprisonment differed between Indigenous and non-Indigenous offenders when they appeared before the court under similar circumstances. Results showed that Indigenous offenders were less likely than their non-Indigenous counterparts to be sentenced to a term of imprisonment when appearing before the court under seemingly similar circumstances. Focal concerns (attribution) perspectives are used to explore these findings.

- Abstract
Background: We used a social network approach to identify influential community organizations within integrated public health networks in three regions in Texas, US: Houston/Harris County, Cameron County, and Northeast Texas. The study aimed to understand how network structures influence organizational performance in COVID-19 response., Methods: In collaboration with community partners in each region, we administered a snowball sampling network data collection. Initial seed sets for the regions of 23, 25, and 55 organizations identified other organizations that then responded to the survey, which expanded the sets to 268, 145, and 138, respectively. Principal component analysis (PCA) identified key network structures-centrality and brokerage-and we introduced two network-based performance measures: Fulfillment Rate (FR), which measures securing needed resources, and Provision Rate (PR), which measures providing resources to others. We tested hypotheses to examine the associations between these network structures and organizational performance., Findings: Centrality consistently emerged as a predictor of organizational performance across all three regions. Community organizations that are more centrally positioned, rather than broker organizations, play a critical role in meeting resource needs and providing services to other organizations. Centrally positioned organizations conducted more COVID-19 tests, whereas brokers administered fewer vaccines., Interpretations: This study suggests that public health interventions should prioritize central organizations for resource allocation and distribution. Our network-based performance metrics offer new avenues for evaluating organizational effectiveness in networked public health systems, with broader applicability to future crises and public health planning., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Peng Wang and Dean Lusher are Co-founders and Directors of SNA Toolbox Pty, Australia.

- Abstract
Introduction: Longitudinal studies can provide timely and accurate information to evaluate and inform COVID-19 control and mitigation strategies and future pandemic preparedness. The Optimise Study is a multidisciplinary research platform established in the Australian state of Victoria in September 2020 to collect epidemiological, social, psychological and behavioural data from priority populations. It aims to understand changing public attitudes, behaviours and experiences of COVID-19 and inform epidemic modelling and support responsive government policy., Methods and Analysis: This protocol paper describes the data collection procedures for the Optimise Study, an ongoing longitudinal cohort of ~1000 Victorian adults and their social networks. Participants are recruited using snowball sampling with a set of seeds and two waves of snowball recruitment. Seeds are purposively selected from priority groups, including recent COVID-19 cases and close contacts and people at heightened risk of infection and/or adverse outcomes of COVID-19 infection and/or public health measures. Participants complete a schedule of monthly quantitative surveys and daily diaries for up to 24 months, plus additional surveys annually for up to 48 months. Cohort participants are recruited for qualitative interviews at key time points to enable in-depth exploration of people's lived experiences. Separately, community representatives are invited to participate in community engagement groups, which review and interpret research findings to inform policy and practice recommendations., Ethics and Dissemination: The Optimise longitudinal cohort and qualitative interviews are approved by the Alfred Hospital Human Research Ethics Committee (# 333/20). The Optimise Study CEG is approved by the La Trobe University Human Ethics Committee (# HEC20532). All participants provide informed verbal consent to enter the cohort, with additional consent provided prior to any of the sub studies. Study findings will be disseminated through public website (https://optimisecovid.com.au/study-findings/) and through peer-reviewed publications., Trial Registration Number: NCT05323799., Competing Interests: Competing interests: Burnet Institute has received investigator initiated clinical research funding form Gilead Sciences, AbbVie and Merck unrelated to this grant., (© Author(s) (or their employer(s)) 2024.

- Abstract
Background: Community engagement is key to developing local and context-specific strategies for the prevention and control of COVID-19. However, expedited research design and approval in the early days of the pandemic may have limited the opportunities for community members to influence pandemic-related research. In this study, we sought to understand how a Community Engagement Group (CEG) could impact a large longitudinal COVID-19 research project (Optimise), when involved solely in the interpretation and knowledge translation phases of the research., Methods: Seven community members were recruited for the CEG, representing a diverse range of groups. Each month, Optimise data of topical importance were compiled into a draft report. The CEG discussed the draft report at their monthly meeting and members' contributions were incorporated into the final report for distribution to policy-makers. In this study, a document analysis was undertaken of ten consecutive reports produced between February and November 2021. Each report was compared pre- and post- the inclusion of CEG contributions, which were then analysed using thematic analysis., Results: Community engagement in the interpretation and knowledge translation phases of Optimise had positive impacts on reports for policy-makers, including grounding the empirical findings in broader community perspectives, identifying policy issues affecting different groups and contributing unique insights beyond the empirical findings. Overall, the CEG contributions demonstrated the complexity of lived experience lying beneath the empirical data., Conclusion: Community engagement in the translation of the Optimise findings resulted in research reports to policy-makers that were reflective of a broader range of community perspectives, and that provided potential solutions to emerging policy issues related to COVID-19. This study adds to the evidence base about the impact of community engagement in the later interpretation and knowledge translation phases of research, particularly in the context of reporting to policy-makers during a public health emergency., (© 2024 The Author(s); Published by Kerman University of Medical Sciences This is an open-access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.)

- Abstract
Objective: Morbidity and mortality from coronavirus disease 2019 (COVID-19) have been significant among elderly residents of residential aged-care services (RACS). To prevent incursions of COVID-19 in RACS in Australia, visitors were banned and aged-care workers were encouraged to work at a single site. We conducted a review of case notes and a social network analysis to understand how workplace and social networks enabled the spread of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) among RACS., Design: Retrospective outbreak review., Setting and Participants: Staff involved in COVID-19 outbreaks in RACS in Victoria, Australia, May-October 2020., Methods: The Victorian Department of Health COVID-19 case and contact data were reviewed to construct 2 social networks: (1) a work network connecting RACS through workers and (2) a household network connecting to RACS through households. Probable index cases were reviewed to estimate the number and size (number of resident cases and deaths) of outbreaks likely initiated by multisite work versus transmission via households., Results: Among 2,033 cases linked to an outbreak as staff, 91 (4.5%) were multisite staff cases. Forty-three outbreaks were attributed to multisite work and 35 were deemed potentially preventable had staff worked at a single site. In addition, 99 staff cases were linked to another RACS outbreak through their household contacts, and 21 outbreaks were attributed to staff-household transmission., Conclusions: Limiting worker mobility through single-site policies could reduce the chances of SARS-CoV-2 spreading from one RACS to another. However, initiatives that reduce the chance of transmission via household networks would also be needed.

- Abstract
Background: Longitudinal studies are critical to informing evolving responses to COVID-19 but can be hampered by attrition bias, which undermines their reliability for guiding policy and practice. We describe recruitment and retention in the Optimise Study, a longitudinal cohort and social networks study that aimed to inform public health and policy responses to COVID-19., Methods: Optimise recruited adults residing in Victoria, Australia September 01 2020-September 30 2021. High-frequency follow-up data collection included nominating social networks for study participation and completing a follow-up survey and four follow-up diaries each month, plus additional surveys if they tested positive for COVID-19 or were a close contact. This study compared number recruited to a-priori targets as of September 302,021, retention as of December 31 2021, comparing participants retained and not retained, and follow-up survey and diary completion October 2020-December 2021. Retained participants completed a follow-up survey or diary in each of the final three-months of their follow-up time. Attrition was defined by the number of participants not retained, divided by the number who completed a baseline survey by September 302,021. Survey completion was calculated as the proportion of follow-up surveys or diaries sent to participants that were completed between October 2020-December 2021., Results: At September 302,021, 663 participants were recruited and at December 312,021, 563 were retained giving an overall attrition of 15% (n = 100/663). Among the 563 retained, survey completion was 90% (n = 19,354/21,524) for follow-up diaries and 89% (n = 4936/5560) for monthly follow-up surveys. Compared to participants not retained, those retained were older (t-test, p < 0.001), and more likely to be female (χ
2 , p = 0.001), and tertiary educated (χ2 , p = 0.018)., Conclusion: High levels of study retention and survey completion demonstrate a willingness to participate in a complex, longitudinal cohort study with high participant burden during a global pandemic. We believe comprehensive follow-up strategies, frequent dissemination of study findings to participants, and unique data collection systems have contributed to high levels of study retention., (© 2023.

- Abstract
COVID-19 has resulted in dramatic and widespread social network interventions across the globe, with public health measures such as distancing and isolation key epidemiological responses to minimize transmission. Because these measures affect social interactions between people, the networked structure of daily lives is changed. Such largescale changes to social structures, present simultaneously across many different societies and touching many different people, give renewed significance to the conceptualization of social network interventions. As social network researchers, we need a framework for understanding and describing network interventions consistent with the COVID-19 experience, one that builds on past work but able to cast interventions across a broad societal framework. In this theoretical paper, we extend the conceptualization of social network interventions in these directions. We follow Valente (2012) with a tripartite categorization of interventions but add a multilevel dimension to capture hierarchical aspects that are a key feature of any society and implicit in any network. This multilevel dimension distinguishes goals, actions, and outcomes at different levels, from individuals to the whole of the society. We illustrate this extended taxonomy with a range of COVID-19 public health measures of different types and at multiple levels, and then show how past network intervention research in other domains can also be framed in this way. We discuss what counts as an effective network, an effective intervention, plausible causality, and careful selection and evaluation, as central to a full theory of network interventions., (© 2022 Elsevier B.V.

- Abstract
Burnout is commonly associated with professions that entail a high rate of close relationships with other individuals or groups. This paper explores the association between burnout and interpersonal relationships using a relational, social network framework. We collected data on advice-seeking relationships among 102 teachers and administrative staff from a secondary school in Melbourne, Australia. Burnout was measured using the Burnout Assessment Tool and we focused on four core subscales: (1) exhaustion; (2) mental distance; (3) emotional impairment; and (4) cognitive impairment. We applied a particular class of statistical model for social networks called Exponential Random Graph Models (ERGMs) to shed new light on how level of burnout relates to formation of advice relations among school staff. Results indicated that high levels of overall burnout were linked to a higher number of advice-seeking ties among school staff. Additionally, teachers who scored high in cognitive impairment (i.e., difficulties in thinking clearly and learn new things at work) tended to seek and to provide advice to a greater number of others. Finally, school staff who scored high in exhaustion (i.e., a severe loss of energy that results in feelings of both physical and mental exhaustion) tended to be sought out less as advisors to others, while those high in mental distance (i.e., psychologically distancing oneself from others) were generally less likely to seek advice from other school staff. We discuss these findings drawing on Conservation of Resource theory. Notably, our results show that burnout is not only an individual-level problem, but that burnout is associated with reduced social connectivity in specific ways that may impact on how other school staff collaborate, culminating in a staff-wide overall impact that affects how schools function., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Aboutalebi Karkavandi, Gallagher, Wang, Kyndt, Lusher, Block and McKenzie.)

- Abstract
Objectives: To profile the long-term mental health outcomes of those affected by the 2009 Black Saturday bushfires and to document the course of mental health since the disaster., Method: The longitudinal Beyond Bushfires study included 1017 respondents (Wave 1; 3-4 years after the fires), 736 (76.1%) at Wave 2 (5 years after the fires) and 525 (51.6%) at Wave 3 (10 years after the fires). The survey indexed fire-related and subsequent stressful events, probable posttraumatic stress disorder, major depressive disorder, alcohol use, severe distress and receipt of health services for mental health problems., Results: Relative to their status 3-4 years after the fires, there were reduced rates of fire-related posttraumatic stress disorder (6.2% vs 12.2%), general posttraumatic stress disorder (14.9% vs 18.7%) and severe distress (4.4% vs 7.5%) at 10 years. There were comparable rates between Wave 1 and Wave 3 for depression (10.9% vs 8.3%) and alcohol abuse (21.8% vs 18.5%). Of people in high-affected regions, 22.1% had posttraumatic stress disorder, depression or severe distress at Wave 3. One-third to one-half of participants who reported probable posttraumatic stress disorder or depression at any assessment did not display the disorder at the next assessment. Worsening of mental health at Wave 3 was associated with the extent of property loss, exposure to recent traumatic events or recent stressful life events. Only 24.6% of those with a probable disorder had sought professional help for this in the previous 6 months., Conclusion: Approximately one-fifth of people from high-affected areas have a probable psychological disorder a decade after the fires. Mental health appears to fluctuate for those who are not consistently resilient, apparently as a result of ongoing stressors. The observation that most people with probable disorder are not receiving care highlights the need for further planning about managing long-term mental health needs of disaster-affected communities.

- Abstract
Sport participation has been shown to be associated with health and social benefits. However, there are persisting inequities and barriers to sport participation that can prevent children and young people with diverse backgrounds and abilities from accessing these benefits. This mixed methods study investigated how diversity is understood, experienced and managed in junior sport. The study combined in-depth interviews (n = 101), surveys (n = 450) and observations over a three-year period. The results revealed that a focus on performance and competitiveness negatively affected junior sports clubs' commitment to diversity and inclusive participation. Gender and a range of attitudes about diversity were also strongly related. On average, we found that those who identified as men were more likely to support a pro-performance stance, be homophobic, endorse stricter gender roles, and endorse violence as a natural masculine trait. In addition, those who identified as men were less likely to hold pro-disability attitudes. These findings suggest that the participation-performance tension and gender affect to what extent, and how, sports clubs engage children and young people with diverse backgrounds and abilities., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Involvement in voluntary associations is a key form of social capital and plays an especially important role following disaster as a venue for coordination and decision-making for the wider community. Yet, relatively little attention has been paid to how group involvement affects mental health, at either the individual or community level. The aim of this study was to assess the impact of involvement in voluntary associations on mental health among residents of bushfire-affected communities. A longitudinal sample of 642 individuals affected by the 2009 Victorian bushfires in south-eastern Australia were surveyed in 2012 and 2014 (3- and 5-years post-disaster). A further subsample (n = 552) of residents residing continuously within 22 bushfire-affected communities were examined for community-level effects using multilevel regression methods. After adjusting for demographics, disaster exposure, and network variables, group involvement at time 1 bore a curvilinear relationship with PTSD at both time points: moderate involvement was most beneficial, with no participation, or high amounts, yielding poorer outcomes. High amounts of group involvement was likewise linked to a greater risk of major depression. Furthermore, communities with higher median levels of group involvement reported lower levels of PTSD symptoms and major depression two years later. With respect to group involvement, more is not always better. For individuals, moderation - if possible - is key. Meanwhile, community-level health benefits come when most people participate to some extent, suggesting that the distribution of involvement across the community is important., (Copyright © 2018 Elsevier Ltd.

- Abstract
Objectives: To map the changing prevalence and predictors of psychological outcomes in affected communities 5 years following the Black Saturday bushfires in Victoria., Method: Follow-up assessment of longitudinal cohort study in high, medium and non-affected communities in Victoria, Australia. Participants included 1017 respondents (Wave 1) interviewed via telephone and web-based survey between December 2011 and January 2013, and 735 (76.1%) eligible participants were retested between July and November 2014 (Wave 2). The survey included measures of fire-related and subsequent stressful events, probable posttraumatic stress disorder, major depressive episode, alcohol use and severe distress., Results: There were reduced rates of fire-related posttraumatic stress disorder (8.7% vs 12.1%), general posttraumatic stress disorder (14.7% vs 18.2%), major depressive episode (9.0% vs 10.9%) and serious mental illness (5.4% vs 7.8%). Rates of resilience increased over time (81.8% vs 77.1%), and problem alcohol use remained high across Wave 1 (22.1%) and Wave 2 (21.4%). The most robust predictor of later development of fire-related posttraumatic stress disorder (odds ratio: 2.11; 95% confidence interval: [1.22, 3.65]), general posttraumatic stress disorder (odds ratio: 3.15; 95% confidence interval: [1.98, 5.02]), major depressive episode (odds ratio: 2.86; 95% confidence interval: [1.74, 4.70]), serious mental illness (odds ratio: 2.67; 95% confidence interval: [0.57, 1.72]) or diminished resilience (odds ratio: 2.01; 95% confidence interval: [1.32, 3.05]) was extent of recent life stressors., Conclusion: Although rates of mental health problems diminished over time, they remained higher than national levels. Findings suggest that policy-makers need to recognize that the mental health consequences of disasters can persist for many years after the event and need to allocate resources towards those who are most at risk as a result of substantive losses and ongoing life stressors.

- Abstract
Objective: Although disasters are a major cause of mental health problems and typically affect large numbers of people and communities, little is known about how social structures affect mental health after a disaster. The authors assessed the extent to which mental health outcomes after disaster are associated with social network structures., Method: In a community-based cohort study of survivors of a major bushfire disaster, participants (N=558) were assessed for probable posttraumatic stress disorder (PTSD) and probable depression. Social networks were assessed by asking participants to nominate people with whom they felt personally close. These nominations were used to construct a social network map that showed each participant's ties to other participants they nominated and also to other participants who nominated them. This map was then analyzed for prevailing patterns of mental health outcomes., Results: Depression risk was higher for participants who reported fewer social connections, were connected to other depressed people, or were connected to people who had left their community. PTSD risk was higher if fewer people reported being connected with the participant, if those who felt close to the participant had higher levels of property loss, or if the participant was linked to others who were themselves not interconnected. Interestingly, being connected to other people who in turn were reciprocally close to each other was associated with a lower risk of PTSD., Conclusions: These findings provide the first evidence of disorder-specific patterns in relation to one's social connections after disaster. Depression appears to co-occur in linked individuals, whereas PTSD risk is increased with social fragmentation. These patterns underscore the need to adopt a sociocentric perspective of postdisaster mental health in order to better understand the potential for societal interventions in the wake of disaster.

- Abstract
Research on mental health following disasters has led to the identification of many individual protective and risk factors for postdisaster mental health. However, there is little understanding of the exact influence that disasters have on the functioning of intimate relationships. Especially relevant are attachment styles, which are likely to play an important role in the provision and perception of social support between partners, and subsequent mental health outcomes. Heterosexual couples (N = 127) affected by the 2009 Victorian "Black Saturday" Bushfires in southeastern Australia were surveyed for disaster experiences, posttraumatic stress disorder (PTSD) symptoms, depression, and attachment style between May 2012 and January 2013, approximately 3 years after the disaster. Using actor-partner interdependence models (APIM), we examined both intrapersonal and interpersonal associations of attachment anxiety and avoidance with depression and PTSD, in combination with shared disaster exposure. Male partners' attachment avoidance was associated with depression and PTSD in both partners. By contrast, a female partner's attachment avoidance was associated with greater depression and PTSD in herself, but fewer PTSD symptoms in a male partner. Amid the chronic stressors of a postdisaster setting, the attachment avoidance of the male partner may play a particularly negative role, with his tendency toward isolation and denial becoming especially maladaptive for the couple as a whole. The female partner's attachment avoidance is likewise an important factor, but its associations with negative social support and relationship breakup must be clarified to understand its impact on partnership functioning.

- Abstract
Short-term separation from close family members during a disaster is a highly salient event for those involved. Yet, its subsequent impact on mental health has received little empirical attention. One relevant factor may be attachment style, which influences patterns of support-seeking under threatening conditions. Individuals (N = 914) affected by the 2009 Victorian bushfires in southeastern Australia were assessed for disaster experiences, depression, posttraumatic stress disorder (PTSD) symptoms, and attachment style 3-4 years after the fires. Using multigroup structural equation modelling, individuals who reported separation from close family members during the bushfires (n = 471) were compared to those who reported no separation (n = 443). Cross-sectional results indicated that separated individuals had higher levels of PTSD symptoms. Furthermore, attachment anxiety was more strongly positively associated with depression among separated (b = 0.62) versus not separated individuals (b = 0.32). Unexpectedly, among separated individuals, attachment avoidance had a statistically weaker association with depression (b = 0.17 vs. b = 0.35) and with PTSD symptoms (b = 0.06 vs. b = 0.22). These results suggest that attachment anxiety amplifies a negative reaction to separation; meanwhile, for avoidant individuals, separation in times of danger may facilitate defensive cognitive processes., (Copyright © 2016 International Society for Traumatic Stress Studies.)

- Abstract
Objective: Research has established the mental health sequelae following disaster, with studies now focused on understanding factors that mediate these outcomes. This study focused on anger, alcohol, subsequent life stressors and traumatic events as mediators in the development of mental health disorders following the 2009 Black Saturday Bushfires, Australia's worst natural disaster in over 100 years., Method: This study examined data from 1017 (M = 404, F = 613) adult residents across 25 communities differentially affected by the fires and participating in the Beyond Bushfires research study. Data included measures of fire exposure, posttraumatic stress disorder, depression, alcohol abuse, anger and subsequent major life stressors and traumatic events. Structural equation modeling assessed the influence of factors mediating the effects of fire exposure on mental health outcomes., Results: Three mediation models were tested. The final model recorded excellent fit and observed a direct relationship between disaster exposure and mental health outcomes (b = .192, p < .001) and mediating relationships via Anger (b = .102, p < .001) and Major Life Stressors (b = .128, p < .001). Each gender was compared with multiple group analyses and while the mediation relationships were still significant for both genders, the direct relationship between exposure and outcome was no longer significant for men (p = .069), but remained significant (b = .234, p < .001) for women., Conclusions: Importantly, anger and major life stressors mediate the relationship between disaster exposure and development of mental health problems. The findings have significant implications for the assessment of anger post disaster, the provision of targeted anger-focused interventions and delivery of government and community assistance and support in addressing ongoing stressors in the post-disaster context to minimize subsequent mental health consequences., (© The Royal Australian and New Zealand College of Psychiatrists 2015.)

- Abstract
There is growing evidence that providing increased voice to vulnerable or disenfranchised populations is important to improving health equity. In this paper we will examine the engagement of Aboriginal community members and community controlled organisations in local governance reforms associated with the Aboriginal Health National Partnership Agreements (AHNPA) in Australia and its impact on the uptake of health assessments. The sample included qualitative and quantitative responses from 188 people involved in regional governance in Aboriginal health. The study included data on the uptake of Aboriginal health assessments from July 2008 to December 2012. The study population was 83190 in 2008/9, 856986 in 2009/10, 88256 in 2010/11 and 90903 in 2011/12. Logistic regression was used to examine the relationships between organisations within forums and the regional uptake of Aboriginal health assessments. The independent variables included before and after the AHNPA, state, remoteness, level of representation from Aboriginal organisations and links between Aboriginal and mainstream organisations. The introduction of the AHNPA was associated with a shift in power from central government to regional forums. This shift has enabled Aboriginal people a much greater voice in governance. The results of the analyses show that improvements in the uptake of health assessments were associated with stronger links between Aboriginal organisations and between mainstream organisations working with Aboriginal organisations. Higher levels of community representation were also associated with improved uptake of health assessments in the AHNPA. The findings suggest that the incorporation of Aboriginal community and community controlled organisations in regional planning plays an important role in improving health equity. This study makes an important contribution to understanding the processes through which the incorporation of disadvantaged groups into governance might contribute to health equity., (Copyright © 2014 The Authors.

- Abstract
Objective: We aimed to map the prevalence and predictors of psychological outcomes in affected communities 3-4 years after the Black Saturday bushfires in the state of Victoria, Australia., Methods: Baseline assessment of a longitudinal cohort study in high-, medium-, and low-affected communities in Victoria. Participants included 1017 residents of high-, medium-, and low-affected fire communities. Participants were surveyed by means of a telephone and web-based interview between December 2011 and January 2013. The survey included measures of fire-related post-traumatic stress disorder (PTSD) and general PTSD from other traumatic events, major depressive episode, alcohol use, and general psychological distress., Results: The majority of respondents in the high- (77.3%), medium- (81.3%), and low-affected (84.9%) communities reported no psychological distress on the K6 screening scale. More participants in the high-affected communities (15.6%) reported probable PTSD linked to the bushfires than medium- (7.2%) and low-affected (1.0%) communities (odds ratio (OR): 4.57, 95% confidence interval (CI): 2.61-8.00, p = 0.000). Similar patterns were observed for depression (12.9%, 8.8%, 6.3%, respectively) (OR: 1.83, 95% CI: 1.17-2.85, p = 0.008) and severe psychological distress (9.8%, 5.0%, 4.9%, respectively) (OR: 2.08, 95% CI: 1.23-3.55, p = 0.007). All communities reported elevated rates of heavy drinking (24.7%, 18.7%, 19.6%, respectively); however, these were higher in the high-affected communities (OR: 1.39, 95% CI: 1.01-1.89, p = 0.04). Severe psychological distress was predicted by fear for one's life in the bushfires, death of someone close to them in the bushfires, and subsequent stressors. One-third of those with severe psychological distress did not receive mental health assistance in the previous month., Conclusions: Several years following the Black Saturday bushfires the majority of affected people demonstrated resilience without indications of psychological distress. A significant minority of people in the high-affected communities reported persistent PTSD, depression, and psychological distress, indicating the need for promotion of the use of health and complementary services, community-based initiatives, and family and other informal supports, to target these persistent problems., (© The Royal Australian and New Zealand College of Psychiatrists 2014.)

- Abstract
The interaction of positive and negative relationships (i.e. I like you, but you dislike me - referred to as relational dissonance) is an underexplored phenomenon. Further, it is often only poor (or negative) mental health that is examined in relation to social networks, with little regard for positive psychological wellbeing. Finally, these issues are compounded by methodological constraints. This study explores a new concept of relational dissonance alongside mutual antipathies and friendships and their association with mental health using multivariate exponential random graph models with an Australian sample of secondary school students. Results show male students with relationally dissonant ties have lower positive mental health measures. Girls with relationally dissonant ties have lower depressed mood, but those girls being targeted by negative ties are more likely to have depressed mood. These findings have implications for the development of interventions focused on promoting adolescent wellbeing and consideration of the appropriate measurement of wellbeing and mental illness.

- Abstract
Background: Natural disasters represent an increasing threat both in terms of incidence and severity as a result of climate change. Although much is known about individual responses to disasters, much less is known about the social and contextual response and how this interacts with individual trajectories in terms of mental health, wellbeing and social connectedness. The 2009 bushfires in Victoria, Australia caused much loss of life, property destruction, and community disturbance. In order to progress future preparedness, response and recovery, it is crucial to measure and understand the impact of disasters at both individual and community levels., Methods/design: This study aims to profile the range of mental health, wellbeing and social impacts of the Victorian 2009 bushfires over time using multiple methodologies and involving multiple community partners. A diversity of communities including bushfire affected and unaffected will be involved in the study and will include current and former residents (at the time of the Feb 2009 fires). Participants will be surveyed in 2012, 2014 and, funding permitting, in 2016 to map the predictors and outcomes of mental health, wellbeing and social functioning. Ongoing community visits, as well as interviews and focus group discussions in 2013 and 2014, will provide both contextual information and evidence of changing individual and community experiences in the medium to long term post disaster. The study will include adults, adolescents and children over the age of 5., Discussion: Conducting the study over five years and focussing on the role of social networks will provide new insights into the interplay between individual and community factors and their influence on recovery from natural disaster over time. The study findings will thereby expand understanding of long term disaster recovery needs for individuals and communities.

- Abstract
Vocal singing (singing with lyrics) shares features common to music and language but it is not clear to what extent they use the same brain systems, particularly at the higher cortical level, and how this varies with expertise. Twenty-six participants of varying singing ability performed two functional imaging tasks. The first examined covert generative language using orthographic lexical retrieval while the second required covert vocal singing of a well-known song. The neural networks subserving covert vocal singing and language were found to be proximally located, and their extent of cortical overlap varied with singing expertise. Nonexpert singers showed greater engagement of their language network during vocal singing, likely accounting for their less tuneful performance. In contrast, expert singers showed a more unilateral pattern of activation associated with reduced engagement of the right frontal lobe. The findings indicate that singing expertise promotes independence from the language network with decoupling producing more tuneful performance. This means that the age-old singing practice of 'finding your singing voice' may be neurologically mediated by changing how strongly singing is coupled to the language system., (Copyright © 2010 Wiley Periodicals, Inc.)

- Abstract
The natural variability of pitch naming ability in the population (known as absolute pitch or AP) provides an ideal method for investigating individual differences in pitch processing and auditory knowledge formation and representation. We have demonstrated the involvement of different cognitive processes in AP ability that reflects varying skill expertise in the presence of similar early age of onset of music tuition. These processes were related to different regions of brain activity, including those involved in pitch working memory (right prefrontal cortex) and the long-term representation of pitch (superior temporal gyrus). They reflected expertise through the use of context dependent pitch cues and the level of automaticity of pitch naming. They impart functional significance to structural asymmetry differences in the planum temporale of musicians and establish a neurobiological basis for an AP template. More generally, they indicate variability of knowledge representation in the presence of environmental fostering of early cognitive development that translates to differences in cognitive ability.

- Abstract
The ability to understand another person's action and, if needed, to imitate that action, is a core component of human social behaviour. Imitation skills have attracted particular attention in the search for the underlying causes of the social difficulties that characterize autism. In recent years, it has been reported that people with autism can bypass some of their social deficits by interacting with robots. However, the robot preference in terms of imitation has yet to be proved. Here we provide empirical evidence that interaction with robots can trigger imitative behaviour in children with autism. We compared a group of high functioning children with autism with a group of typically developing children in a visuomotor priming experiment. Participants were requested to observe either a human or a robotic arm model performing a reach-to-grasp action towards a spherical object. Subsequently, the observers were asked to perform the same action towards the same object. Two 'control' conditions in which participants performed the movement in the presence of either the static human or robot model were also included. Kinematic analysis was conducted on the reach-to-grasp action performed by the observer. Our results show that children with autism were facilitated - as revealed by a faster movement duration and an anticipated peak velocity - when primed by a robotic but not by a human arm movement. The opposite pattern was found for normal children. The present results show that interaction with robots has an effect on visuomotor priming processes. These findings suggest that in children with autism the neural mechanism underlying the coding of observed actions might be tailored to process socially simpler stimuli.

- Abstract
Purpose: The aims of the present article were the following: (i) to provide some evidence of the potential of virtual reality (VR) for the assessment, training and recovery of hemispatial neglect; (ii) to present data from our laboratory which seem to confirm that the clinical manifestation of neglect can be improved by using VR techniques; and (iii) to ascertain the neural bases of this improvement., Methods: We used a VR device (DataGlove) interfaced with a specially designed computer program which allowed neglect patients to reach and grasp a real object while simultaneously observing the grasping of a virtual object located within a virtual environment by a virtual hand. The virtual hand was commanded in real time by their real hand., Results: After a period of training, hemispatial neglect patients coded the visual stimuli within the neglected space in an identical fashion as those presented within the preserved portions of space. However it was also found that only patients with lesions that spared the inferior parietal/superior temporal regions were able to benefit from the virtual reality training., Conclusions: It was concluded that using VR it is possible to re-create links between the affected and the nonaffected space in neglect patients. Furthermore, that specific regions may play a crucial role in the recovery of space that underlies the improvement of neglect patients when trained with virtual reality. The implications of these results for determining the neural bases of a higher order attentional and/or spatial representation, and for the treatment of patients with unilateral neglect are discussed.

- Abstract
The aims of the present study were to investigate whether the processing of an object shadow occurs implicitly, that is without conscious awareness, and where physically within the human brain shadows are processed. Here we present neurological evidence, obtained from studies of brain-injured patients with visual neglect, that shadows are implicitly processed and that this processing may take place within the temporal lobe. Neglect patients with lesions that do not involve the right temporal lobe were still able to process shadows to optimize object shape perception. In contrast, shadow processing was not found to be as efficient in neglect patients with lesions that involve the right temporal lobe.
