Travel Demand Management (TDM) initiatives are widely applied by transport planners to establish and enable appropriate use of critical transport infrastructure. Less attention has been given to the specific case of TDM in an education precinct (university) context. Travel Plans have been promoted as a means for an organisation to encourage sustainable travel choices by their employees, visitors and customers. This paper offers an empirical contribution to the literature through a comparative qualitative evaluation of selected University Sustainable Travel Plans (USTPs) in Australia to identify the most important questions that a USTP should address explicitly. The evaluation comprised identification of a set of evaluation questions, completion of a template for each USTP considered and application of a simple scoring exercise. We also identify TDM measures that have been introduced as part of a USTP in response to the typical travel patterns exhibited in university settings. A contribution of this paper is to create a means of comparison of USTPs and to establish the components of a comprehensive travel plan. • Conducts a comparative analysis of University Sustainable Travel Plans. • Explores international experience of Travel Demand Management (TDM) in an education precinct context. • Key components of University Sustainable Travel Plans are identified. • The important role of regular surveys of staff and student travel behaviour is highlighted.

This paper profiles Australian universities’ website communications about sustainability initiatives, especially relating to Talloires Declaration signification and the ten recommended actions. The research involves a content study of Talloires signatories’ websites and their semiotic and signaling theory aspects across time. The source is publicly available information (time period 2014 and 2015 respectively) in context with education for sustainable development (ESD) in society and the transaction model in communication theory. It is found that some of the signatory universities in Australia exemplify a few of the Talloires ten agreed actions in their public communications, but each point is not emphasised with equal priority. The variance may be due to divergent underlying objectives; such as public communication of Talloires toward genuine benefit for the environment, or to create a strategic positioning tool to signal the university as an environmental champion within the broader society. Focusing upon secondary data from signatory university websites in Australia, the paper provides a study of higher education signification of Talloires. It assists the initial understanding of signaling theory in the public communication transactions that promote Talloires action and implementation. The findings encourage further studies of related communication issues in universities in other countries. The paper also deepens local and global understanding of perceptions of sustainability and contributes to the body of comparative literature of sustainability in higher education as a development component of strategic management of ESD.

The aim is to present outcome and engagement data from the initial years of the implementation of a new teaching approach in entry to practice nursing and midwifery education. The Block Model (TBM) is a teaching approach that involves studying one unit of study at a time over a four-week period, as opposed to the traditional semester model. This paper presents data revealing the impact of TBM on student engagement and overall experience in entry to practice Bachelor of Nursing and Midwifery programs. The evaluation retrospectively compared key indicators pre- Block Model implementation with outcomes for nursing and midwifery students using TBM approach using standard data sets and external comparators such as the Student Experience Survey and National Employability Survey. The study presents a comparative analysis of key indicators and graduate outcomes for students. We use reportable data and two external comparators, the Student Experience Survey and the National Employability Survey, to gauge student learning and graduate employability. The evaluation was conducted in a tertiary institution in Australia with for nursing and midwifery students who completed their studies using TBM approach at the university. The implementation of TBM in nursing and midwifery programs resulted in improvements in learner engagement, retention rates and pass rates. Improvements were also noted graduate outcomes, with an increase in full-time graduate employment. The results suggest the Block Model is a promising new teaching approach in nursing and midwifery education, with potential benefits for learner engagement, retention and pass rates.

Both developed and developing countries have committed to reduce their emissions through the increased use of renewable energy. This paper aims to compare renewable energy deployment in developed and developing countries represented by Australia and China. The paper firstly argues the validity of comparison of renewable energy deployment in Australia and China. Then, the governance structures in both countries are compared; the paper also compares management mechanisms in terms of funding and incentive support, renewable energy grid-connection and coordination between different levels of governments in both countries. Moreover, the current status of renewable energy development in two countries is summarized. From the study, it can be concluded both countries have set a Renewable Energy Target and promulgated legislation and regulations to enlarge the scale of renewable energy; China shows a stronger commitment to renewable energy than Australia. However, Renewable Energy Certificate mechanism is implemented more effectively in Australia than in China. The paper suggests: augmenting and rebuilding the electricity network and strengthening coordination between different levels of governments for both countries; enhancing manufacturing facilities and incentives for the solar and wind industry for Australia, while developing more-detailed implementation legislation and renewable power quota system for China.

Purposes: This study aimed to compare between electronic medication administration records and paper-based records in the nursing time spent on various activities in a medication round and the medication administration processes followed by nurses in an Australian residential aged care home. It also aimed to identify the benefits and unintended adverse consequences of using the electronic medication administration records.Methods: Time-motion observation, taking of field notes, informal conversation and document review were used to collect data in two units of a residential aged care home. Each unit had one nurse administer medication. Seven nurses were observed over 12 morning shifts. Unit 1 used electronic medication administration records and Unit 2 used paper-based records.Results: No significant difference between the two units was found in the nursing time spent on various activities in a medication round, including documentation, verbal communication, medication administration, infection control and transit. Comparison of the medication administration processes between the electronic and paper-based medication administration records identified a procedural problem which violated the organization's documentation requirement. This problem was documenting before providing medication to a resident when using the paper-based records. It was not observed with the electronic medication administration records. Benefits of introducing the electronic medication administration records included improving nurses' compliance with documentation requirements, freedom from the error of signing twice, reducing the possibility of forgetting to medicate a resident, facilitating nurses to record the time of medication administration to a resident and increasing documentation space. Unintended adverse consequences of introducing the electronic medication administration records included inadequate information about residents, late addition of a new resident's medication profile in the records and nurses' forgetting to medicate a resident due to power outage of the portable device.Conclusions: The electronic medication administration records may not change nursing time spent on various activities in a medication round or substantially alter the medication administration processes, but can generate both benefits and unintended adverse consequences. Future research may investigate whether and how the adverse consequences can be prevented. [ABSTRACT FROM AUTHOR]

Background: Minimally adequate treatment (MAT) is intended to represent treatment minimally sufficient for common mental health problems. For children, MAT has been defined over a twelve-month period as either eight or more mental health visits, or four to seven visits plus relevant medication. MAT is used to identify those missing out on adequate care, but it is unknown whether MAT improves children's outcomes.Methods: This paper examines whether MAT is associated with improved outcomes for children. It uses survey data from the nationally representative Longitudinal Study of Australian children on 596 children with mental health problems based on the Strengths and Difficulties Questionnaire at ages 8-15 years, linked to health service administrative data from 2012 to 2016. Statistical analysis examines the association of MAT with later quality of life (Pediatric Quality of Life Inventory), using a lagged dependent variable model to account for time-varying unobserved confounding.Results: Compared to children with lower levels of treatment, those who received MAT between baseline and follow up had no statistically significant improvement in either quality of life or mental health symptoms.Limitations: The observational data provide insight into real-world practice but require statistical methods to account for selection into treatment.Conclusions: While clinical trials show mental health treatments can be efficacious, this study shows no evidence that children receiving MAT in routine practice have better outcomes. These findings demonstrate the need for better understanding of the nature and impact of children's mental health care as it is delivered and received in routine practice. [ABSTRACT FROM AUTHOR]

• We will monitor compliance with the intervention and adverse events. • Data will be analyzed following intention-to-treat principles. • A cost-effectiveness analysis will be performed. This a priori statistical analysis plan describes the methods of analysis for the Trial Of Prevention Strategies for low back pain (TOPS). TOPS aimed to investigate the effectiveness and cost-effectiveness of exercise and education classes compared with a minimal intervention control in preventing recurrence of low back pain (LBP) in people who have recently recovered from an episode of LBP. TOPS is a superiority, pragmatic, parallel-group randomized controlled trial with allocation concealment, blinded outcome assessors, and intention-to-treat analysis. Participants were randomized to a physical therapist-led exercise and education program for 12 weeks or minimal intervention. The primary outcome was days to recurrence of an episode of LBP. The three key secondary outcomes were days to recurrence of an episode of LBP resulting in (1) activity limitation, (2) care seeking for LBP; and (3) work absence of at least 1 day. Differences in survival curves for the primary (days to recurrence) and secondary outcome (days to LBP with activity limitation, days to care seeking due to LBP, and days to work absence due to LBP) will be compared using Cox regression. Hazard ratios (HRs) and median survival times with 95% confidence intervals (CI) will be calculated. The number of adverse events, including serious adverse events will be reported and the proportion of adverse events between groups will be compared using a Chi-squared test. This paper will provide a detailed description of the planned analyses for the TOPS trial. Australian New Zealand Clinical Trials Registry (ACTRN12615000939594). [ABSTRACT FROM AUTHOR]

Using temporal or spatial analogues is a well developed technique for comparative studies that can shed light on past environments or inform changes in practice by reference to analogue locations. Recently, studies have begun to employ analogue techniques to inform on future conditions under climate change. This paper explores the breadth of application of analogue approaches and seeks to question whether there are the limits to the way in which the technique can be applied. We consider the case of policy in a wide range of land use relevant factors, using case studies of three Australian states. The analysis examines whether existing policy in land use planning, housing, infrastructure, health and ecological services in analogue communities can inform future policy in target communities, so as to fast track their policy development as climate changes. We highlight a number of situations where evidence supports the argument but we conclude that, over the full spectrum of policy, there is insufficient evidence to suggest that analogue approaches are valuable as a policy development tool. The paper outlines the reasons why the approach is limited in the case of land use policy. [ABSTRACT FROM AUTHOR]

• Adoption of potable water reuse in US and Australia analysed using Process Tracing. • Collaborative and transparent regulation contributes to public acceptance of reuse. • Multi-level risk-based regulation would support wider uptake of reuse technology. Highly treated wastewater supplied for potable or non-potable purposes, or 'water reuse,' is a promising additional source of supply in water-scarce areas. However, the adoption of water reuse has been constrained by a lack of public acceptance of the technology, in particular for potable use. The development of regulatory frameworks for reuse may help to address safety concerns and support adoption. This paper investigates the interaction between regulation, public acceptance and technology adoption for potable reuse. It employs a Process Tracing methodology to analyse two country cases, the US and Australia, both of which have experience in successful adoption of potable reuse as well as examples of public resistance and abandonment of specific projects. The cases suggest that local, collaborative, transparent risk-based regulation contributes to increased acceptance of reuse among the public and government officials and supports take-up of the technology.

Introduction: The Australia New Zealand Trauma Registry enables the collection and analysis of standardised data about trauma patients and their care for quality improvement, injury prevention and benchmarking. Little is known, however, about the needs of providers and clinicians in relation to these data, or their views on trauma quality improvement priorities. As clinical experts, trauma clinicians should have input to these as ultimately their practice may be influenced by report findings. This paper presents the perspectives of multidisciplinary trauma care professionals in Australia and New Zealand about the use of the Australia New Zealand Trauma Registry data and trauma quality improvement priorities.Methods: An exploratory survey of trauma professionals from relevant Australia and New Zealand professional organisations was conducted using the Snowballing Method between September 2018 and February 2019. Participants were recruited via a non-random sampling technique to complete an online survey. Descriptive statistical and content analyses were conducted.Results: The data use priorities identified by 102 trauma professionals from a range of locations participated were clinical improvement and system/process improvement (86.3%). Participants reported that access to trauma data should primarily be for clinicians (93.1%) and researchers (87.3%). Having a standardised approach to review trauma cases across hospitals was a priority in trauma quality improvement.Conclusion: Trauma registry data are under-utilised and their use to drive clinical improvement and system/process improvement is fundamental to trauma quality improvement in Australia and New Zealand.

Abstract: Can sustainability and adaptability be integrated in a single decision tool for designing future buildings? Indeed, it is not possible to know what lies ahead for future buildings but, using current research on sustainability and the impact on natural resources and climate, it is possible to forecast the connection between built environment activity and sustainability. This paper demonstrates that the assessment of future adaptation in newly designed building is achievable by using the adaptSTAR model. This new design-rating tool, based on detailed analysis of 12 award-winning adaptive reuse projects in Australia, will assist designers in making decisions to achieve optimum efficiency and useful life from their creations. This paper reports on the second and last stages of the research used in the development of the rating tool. The use of the adaptSTAR model can empower designers of buildings to make critical decisions that contribute to improving longevity and future reuse, thereby ensuring that future building adaptive reuse will foster sustainable built environments. In order to validate the tool, results are compared to Langston's ARP model. It is found that both models are strongly correlated. Furthermore, when improvements to the case studies are proposed, lower ARP scores are computed since the buildings are expected to become obsolete later in their life cycle than a design reflecting poorer performance. It can be observed that the improved designs for each case study out-perform the as-built designs, as indicated by the higher adaptSTAR scores, while the relationship between adaptSTAR and ARP is strengthened.

Taiwan and Australia are non-Parties to the UNESCO Convention on the Protection of the Underwater Cultural Heritage (UCH Convention). However, as the first two non-Parties in the East Asia region, both have incorporated the spirit and letter of the UCH Convention into their respective domestic laws, with minor exceptions to fit into their respective historical and cultural contexts, as well as their administrative and judicial settings. This paper traces and compares the very different origins of these two pieces of UCH specific domestic legislation. A comparative analysis is also made of the structure and content, similarities and differences of each piece of legislation as well as deviations between them and between the UCH Convention. The paper argues that the Taiwanese and Australian experience demonstrates models for the successful incorporation of the UCH Convention for States striving for the preservation, protection and management of UCH.

Abstract: The emergence of Intelligent Transport Systems (ITS) has been recognised with many initiatives during the last 20 years. In Europe, the “ITS Action Plan” identifies a number of applications as key elements contributing to the efficient co-ordination of the overall transport chain. The context and experience surrounding the recent widespread development of technological tools and ICT platforms to support the emergence of ITS are notable for the way in which they permeate the transport and logistics chain. But a key question remains: to what extent is the public transport sector able to exploit the wider benefits of ITS? This paper provides a comparative analysis of ITS policy between Europe and Australia. With a focus on the applications and methods adopted in the use of ITS in the public transport sector in Australia the paper critiques their effectiveness in enhancing passenger experience, operator effectiveness and the likely effect on patronage. The relatively low incidence of the use of ITS in the public transport system in Australia, as compared to Europe, is discussed in the context of technology trends/pathways and impediments to deployment in the public transport sector.

Abstract: Objective: This paper introduces a new method to calculate relative risks of elevated hearing thresholds, at various ages and frequencies, between a study population and ISO1999:2003: Annex A Screened, Annex B Unscreened and ISO1999 Section 5.3 adjustment for noise exposure using Annex A Screened data. We demonstrate this method on a study population of male Royal Australian Air Force personnel. Study Design: Using a retrospective cohort design, hearing thresholds were assessed in 583 F-111 aircraft maintenance personnel, 377 technical-trade comparisons and 492 non-technical comparisons using pure-tone audiometry. A quantile regression model was used determine whether an association exists between median hearing thresholds and F-111 maintenance, adjusting for possible confounders. The new method involves using quantile regression models with bootstrapped standard errors to estimate percentiles for the study population and thus determine the probability of a greater than 25 dB hearing threshold. This was done for the three ISO datasets as follows; for the ISO1999 Annex A screened population data the formula provided allows the calculation of these probabilities. ISO1999 Annex B unscreened population data only provides the values for the 10th, 50th and 90th percentiles at ages 30, 40, 50 and 60 only, therefore it was necessary to fit a curve to these values in order to estimate the probabilities. For ISO1999 Section 5.3 adjustment for noise exposure population we used the Annex A screened population data plus the formula. The probabilities were then divided to give the relative risks of a greater than 25 dB hearing threshold, at various ages and frequencies. Results: While no difference was observed between the three groups, the model identified a number of significant confounders, namely tinnitus, smoking, diabetes and the use of anti-depressant medications. Relative risks were high at frequencies 2 kHz and less for the study population of all ages compared to ISO A screened data. The increased relative risks at 4 and 6 kHz give the appearance of a "noise notch" for ages 30 and 40 years. The comparison with the ISO B unscreened data are significantly less than one for frequencies above 2 kHz, particularly for young men and greater than one less than 2 kHz. The relative risks for the comparison to the ISO A screened data with ISO 5.3 adjustments, are highest for young men decreasing with age, with the highest relative risk are at frequencies less than 2 kHz. Conclusions: This paper demonstrates a new method for quantifying the probability of a clinically relevant hearing loss and the relative risk of the loss due to a risk factor. Prior to this, researchers were reduced to simplistic methods such as visual comparison of deciles which did not enable the estimation of risk. The new method can use all observed hearing thresholds per study participant, adjust for known confounding factors such age and gender, and calculate the relative risk of a clinically relevant increase in hearing threshold due to a risk factor of interest.

Abstract: Over the past decade, several new approaches have emerged to renewable energy education that seek to address the needs of the 21st century for sustainable energy supply systems. In addition, unlike conventional architectural education which does not cover renewable energy issues in its curriculum, these days, renewable energy education has an identity of its own within the discipline of architecture. This paper will clarify academic obstacles that are impeding the development of sustainable architectural education. These obstacles include: ambiguous definitions of sustainable architecture, confusion over the meaning of sustainability, and lack of experts in this field. In the last part of this paper we compare academic architectural education in the field of renewable energy in two countries, Iran as a developing country in Asia and Australia as a developed country in Oceania. Lessons can be drawn from these case studies in regard to the obstacles and progress in the development of sustainable architecture education. [Copyright &y& Elsevier]

Abstract: This paper presents a summary of the main international and national regulations for geologic storage of carbon dioxide. The international group includes the EU Directives, London Convention, and OSPAR. For the national regulations, three countries were covered in this study: United States, Canada, and Australia. In addition to these regulations, a group of guidelines and best practice manuals were also included in this study. As discussion, although this paper recognizes that current legislations have contributed for the regulation of this technology, it is still necessary the development of new rules in other regions. Industry will not invest in large CCS plants without such regulations because of high CCS costs and large financial risks related to CCS. [Copyright &y& Elsevier]

Many countries embarked on reforms of mental health law in the wake of the Convention on the Rights of Persons with Disabilities. These reforms have had varying levels of success. This paper considers the experience of consumers in the Victorian mental health system, drawing on an evaluation that asked consumers and clinicians about their knowledge and experience of rights under the Victorian Mental Health Act, 2014. The data show that consumers were not informed of their rights, were not involved in decisions about treatment, were not able to access safeguards, and could not exercise their rights. The explanations for this include limited staff time, unclear delegations of responsibility, a lack of knowledge, training, and support for rights, and a preference for 'best interests' approaches. The paper identifies tangible reforms that would maintain rights for consumers, including competent refusal of treatment, legislative and regulatory reforms, and training and resourcing. Consumers in this study found that the rights-based framework in the Mental Health Act, 2014 had such an insignificant effect on clinical mental health practice in Victoria that their rights appeared to be illusory.

Summary: Sports scientists require a thorough understanding of the energy demands of sports and physical activities so that optimal training strategies and game simulations can be constructed. A range of techniques has been used to both directly assess and estimate the physiological and biochemical changes during competition. A fundamental approach to understanding the contribution of the energy systems in physical activity has involved the use of time–motion studies. A number of tools have been used from simple pen and paper methods, the use of video recordings, to sophisticated electronic tracking devices. Depending on the sport, there may be difficulties in using electronic tracking devices because of concerns of player safety. This paper assesses two methods currently used to measure player movement patterns during competition: (1) global positioning technology (GPS) and (2) a computer-based tracking (CBT) system that relies on a calibrated miniaturised playing field and mechanical movements of the tracker. A range of ways was used to determine the validity and reliability of these methods for tracking Australian footballers for distance covered during games. Comparisons were also made between these methods. The results indicate distances measured using CBT overestimated the actual values (measured with a calibrated trundle wheel) by an average of about 5.8%. The GPS system overestimated the actual values by about 4.8%. Distances measured using CBT in experienced hands were as accurate as the GPS technology. Both systems showed relatively small errors in true distances. [Copyright &y& Elsevier]

Internet access is determined by a combination of a widely available telecommunication infrastructure and affordability of Internet services, which are closely related to government policies (IT Group. (1999). Like other countries, both Australia and China have considered the Internet a powerful tool for national development economically and socially. As Internet growth becomes more and more significant, it becomes important to address the extent to which the underlying communication policies influence current growth rates. This paper provides a comparative review of policy approaches to regulating the Internet in both China and Australia. This study aims to identify the regulatory factors affecting Internet access in terms of availability and affordability, especially those factors which encourage the creation of a policy and regulatory environment favourable to the development of Internet infrastructure and access. This paper examines the linkages between regulatory regimes, market environments and Internet access in both China and Australia. The preliminary result suggests that government policies governing the telecommunications service market and promoting information infrastructure have a significant impact on the affordability and availability of Internet access. The most significant factor is the level of competition permitted in the telecommunication sector. It has become clear that further regulatory initiatives such as deregulatory mechanisms and interconnection regimes are needed to establish a more competitive environment for Internet access in both countries, and more particularly in China.

The high prevalence of post traumatic stress disorder (PTSD) among people with heroin dependence and its impact on short term outcomes has been well established. The impact of PTSD on long-term recovery is, however, unknown. This paper examines the impact of current and lifetime PTSD on long-term recovery from heroin dependence among participants who took part in the 11-year follow-up of the Australian Treatment Outcome Study (ATOS), a prospective naturalistic longitudinal study of 615 people with heroin dependence recruited from Sydney, Australia, in 2001-2002. Seventy-one percent of the cohort (n = 431) were re-interviewed 11-years post study entry. Outcomes examined included heroin and other drug use, dependence, general physical and mental health, depression, PTSD, employment, and the incidence of trauma exposure, overdose, imprisonment, and attempted suicide over the 11- year follow-up. Despite having a poorer profile at baseline, individuals with current PTSD or a history of PTSD at baseline demonstrated similar levels of improvement to those without a history of PTSD in all outcome domains across the 11-year follow-up, PTSD was associated with consistently higher levels of major depression, and attempted suicide, subsequent trauma exposure, and poorer occupational functioning across the 11-year follow-up. These findings highlight the importance of interventions aimed at occupational rehabilitation, reducing the likelihood of retraumatisation, and addressing PTSD and associated comorbidities among people with heroin dependence.

Background: Compared to the general population, among gay and bisexual men (GBM) prevalence rates of anxiety and depression, and of drug use, are high.Objective: This paper explores the relationship between mental health, sexual risk behavior, and drug use among Australian GBM. We identify factors associated with indicators of poor mental health.Methods: Between September 2014 and July 2017, 3017 GBM responded to measures of anxiety and depression in an online cohort study of drug use.Results: Mean age was 35.3 years (SD 12.8). 17.9% screened positive for current moderate-severe anxiety and 28.3% for moderate-severe depression. The majority (52.2%) reported use of illicit drugs in the previous six months, including 11.2% who had used methamphetamine. One third had high (20.4%) or severe (10.6%) risk levels of alcohol consumption, and 18.3% who were current daily smokers. Most illicit drug use in general was not associated with either anxiety or depression, but men who used cannabis were more likely to show evidence of depression (p = 0.005). Among recent methamphetamine users, 28.0% were assessed as dependent: dependent users were more likely to show evidence of both depression and anxiety than were non-dependent users. High or severe risk drinking was associated with depression and daily tobacco use was associated with both anxiety and depression. Depression and anxiety was associated with: less personal support, viewing oneself as 'feminine', and being less socially engaged with gay men. Sexual risk behavior was not associated with either depression or anxiety.Conclusion: Prevalence of anxiety and depression was high, as was prevalence of licit and illicit drug use. Substance use was associated with anxiety and depression only when the use was considered problematic or dependent. Social isolation and marginalization are strong drivers of poor mental health, even within this population for whom anxiety and depression are common. [ABSTRACT FROM AUTHOR]

Much research concerning drug use in the context of sexual activity among gay and bisexual men derives from public health scholarship. In this paper, we critically examine how the relationship between methamphetamine use and sexual risk practice is treated and understood in this body of research. While public health has made important contributions to establishing the link between methamphetamine use and sexual risk-taking, the precise nature of the relationship is not well defined. This creates space for ungrounded assumptions about methamphetamine use to take hold. We outline what appear to be two dominant interpretations of the methamphetamine/sexual practice relationship: the first proposes that methamphetamine has specific pharmacological properties which lead to sexual disinhibition, risky behaviour and poor health outcomes; the second proposes that methamphetamine attracts men who are already inclined toward highly sexualised interactions and risky practice, and that such men are likely to engage in these practices with or without drugs. We suggest that both interpretations are problematic in that they individualise and cast drug and sex practices as inherently risky and biopsychologically determined. We outline a more historically, socially and politically engaged way to understand methamphetamine use in the context of sexual activity by drawing on the concept of sex-based sociality and the ways in which gay and bisexual men may use methamphetamine and sex as social resources around which to build identities, establish relationships, participate in gay communities, and maximise pleasure while protecting themselves and others from harm.

Background: Pre-drinking is often defined as an economically-minded set of drinking practices engaged in prior to attending public entertainment areas, such as licensed venues. This paper explores motivations and practical considerations that a sample of teenagers describes as significant to 'pre-drinking', despite not attending licensed premises during their most recent risky drinking session.Methods: Data were derived from the mixed-methods Young Australians Alcohol Reporting System (YAARS) project. 16 participants aged 16-19 were identified as pre-drinking on their most recent risky drinking session, followed by subsequent alcohol consumption in non-licensed venues. 4 members of this subsample also undertook qualitative interviews.Results: These data expand on existing understandings of pre-drinking by emphasising the breadth of motivations and practical considerations understood to shape both pre-drinking practices, and subsequent drinking in other public entertainment areas. These primarily included desires for personal enhancement and experiencing freedom over restriction, the dynamics of accessing alcohol and private space, the necessity of opportunism, and concerns regarding parents and other authority figures.Conclusions: Analyses of groups obscured by dominant definitions of what constitutes 'pre-drinking' illuminate a broader range of motivations and concerns facing young people who drink. Such findings enhance our understanding of young people's drinking practices, the terminology used to describe them, and the development of relevant policies and interventions.

Background: There is significant interest in comparing countries on many different indicators of social problems and policies. Cross-national comparisons of drug prevalence and policies are often hampered by differences in the approach used to reach respondents and the methods used to obtain information in national surveys. The paper explores how much these differences could affect cross-country comparisons.Methods: This study reports prevalence of drug use according to the most recent national household survey and then adjusts estimates as if all national surveys used the same methodology. The analysis focuses on European countries for which the European Monitoring Centre for Drugs and Drug Addiction reports data, the United States, Canada, and Australia. Adjustment factors are based on US data.Findings: Adjusting for modality differences appears likely to modestly affect the rankings of countries by prevalence, but to an extent that could be important for comparisons. For example, general population surveys suggest that the US had some of the highest cannabis and cocaine prevalence rates circa 2012, but this is partially driven by the use of a modality known to produce higher prevalence estimates. This analysis shows that country rankings are partly an artifact of the mode of interview used in national general population surveys.Conclusions: Our preliminary efforts suggest that cross-national prevalence comparisons, policy analyses and, other projects such as estimating the global burden of disease could be improved by adjusting estimates from drug use surveys for differences in modality. Research is needed to create more authoritative adjustment factors. [ABSTRACT FROM AUTHOR]

Bullying in health workplaces has a negative impact on nurses, their families, multidisciplinary teams, patient care and the profession. This paper compares the experiences of Australian and UK baccalaureate nursing students in relation to bullying and harassment during clinical placement. A secondary analysis was conducted on two primary cross-sectional studies of bullying experiences of Australian and UK nursing students. Data were collected using the Student Experience of Bullying during Clinical Placement (SEBDCP) questionnaire and analysed using descriptive and inferential statistics. The total sample was 833 Australian and 561 UK students. Australian nursing students experienced a higher rate of bullying (50.1%) than UK students (35.5%). Students identified other nurses as the main perpetrators (Aust 53%, UK 68%), although patients were the main source of physical acts of bullying. Few bullied students chose to report the episode/s. The main reason for non-reporting was fear of being victimised. Sadly, some students felt bullying and harassment was ‘part of the job’. A culture of bullying in nursing persists internationally. Nursing students are vulnerable and can question their future in the ‘caring’ profession of nursing after experiencing and/or witnessing bullying during clinical placement. Bullying requires a zero tolerance approach. Education providers must develop clearer policies and implement procedures to protect students - the future nursing workforce. [ABSTRACT FROM AUTHOR]

Australia's largest cities are more mono-centric than most US cities and may be over-centralising, particularly in terms of office employment. Government worker relocation programs are being employed with policy debate over what should be an ideal urban structure including in terms of travel behaviour. The paper explores research approaches to explore transport impacts of employment decentralization. A review shows the results of: surveys of workers moved to suburban locations; longitudinal analyses of transport and land use changes in city-regions using cross-sectional census or HTS data; comparative analysis of urban structure variables across cities using similar datasets; combinations of longitudinal and comparative research; and, scenario-based modelling approaches. A modelling framework is then developed to appraise the possible transport impacts of decentralization in Brisbane. To test the possibilities further, two decentralization scenarios modelled and compared. Decentralization mostly to middle-suburban locations better addresses jobs-housing balance and maximises proposed new public transport services, producing good transport outcomes. However, decentralization to outer-suburban locations in Brisbane exacerbates the propensity for decentralization to increase travel distances, especially by car. [ABSTRACT FROM AUTHOR]

Background: Between 1992 and 2012 dispensing episodes for pharmaceutical opioids (PO) in Australia increased from 500000 to 7500000. In the US, increases in the prescription of PO have been linked to increases in opioid-related morbidity and mortality and transitions to heroin injection. However, Australian data indicate that morbidity and mortality related to PO are relatively low, particularly when compared to heroin and other drugs. This paper explores the characteristics and patterns of non-medical pharmaceutical opioid (NMPO) use among a sample of young people in Sydney, Australia.Methods: During 2015, we conducted in-depth qualitative interviews with 34 young people who use PO non-medically by oral (n=22) and intravenous (n=12) routes of administration.Results: Oral NMPO users were a more affluent group who clustered around the Northern, Inner and Eastern suburbs of Sydney, while the intravenous users came from a range of locations including rural/regional areas of NSW and socioeconomically disadvantaged suburbs of South Western Sydney. Oral users were characterised by intermittent and largely self-limiting NMPO use and reported few health and social consequences. Intravenous users reported heavy and frequent drug, including NMPO, use and a range of adverse health and social consequences including overdose, injecting risk behaviour, hepatitis C virus (HCV) infection and residential instability.Conclusion: Results highlight the significance of social and structural factors in trajectories of opioid use and related harms. Factors such as stable housing and family relationships, disposable income and close social networks observed in young oral NMPO users may help to explain differences in patterns of NMPO use and related outcomes between the two groups.

Introduction: Physical injury is a leading cause of death and disability among children worldwide and the largest cause of paediatric hospital admission. Parents of critically injured children are at increased risk of developing mental and emotional distress in the aftermath of child injury. In the Australian context, there is limited evidence on parent experiences of child injury and hospitalisation, and minimal understanding of their support needs. The aim of this investigation was to explore parents' experiences of having a critically injured child during the acute hospitalisation phase of injury, and to determine their support needs during this time.Methods: This multi-centre study forms part of a larger longitudinal mixed methods study investigating the experiences, unmet needs and well-being of parents of critically injured children over the two-year period following injury. This paper describes parents' experiences of having a child 0-13 years hospitalised with critical injury in one of four Australian paediatric hospitals. Semi-structured interviews were conducted with forty parents and transcribed verbatim. The data were managed using NVIVO 10 software and thematically analysed.Findings: Forty parents (26 mothers and 14 fathers) of 30 children (14 girls and 16 boys aged 1-13 years) from three Australian States participated. The majority of children were Australian born. Three main themes with sub-themes were identified: navigating the crisis of child injury; coming to terms with the complexity of child injury; and finding ways to meet the family's needs.Conclusions: There is a need for targeted psychological care provision for parents of critically injured children in the acute hospital phase, including psychological first aid and addressing parental blame attribution. Parents and children would benefit from the implementation of anticipatory guidance frameworks informed by a family-centred social ecological approach to prepare them for the trauma journey and for discharge. This approach could inform care delivery throughout the child injury recovery trajectory. The development and implementation of a major trauma family support coordinator in paediatric trauma centres would make a tangible difference to the care of critically injured children and their families.

Over the last decade, various concepts with similar underlying philosophies have evolved within the urban water sector calling for a more integrated, sustainable, and adaptive management approach. Whilst many advocate this idea, the process of transitioning to sustainability-focused water management seems to proceed slowly. There are sector-specific characteristics that generally bring a level of conformity within the sector, but various national and regional drivers and constraints also shape each utility's option space. Business models can be useful catalysts for change by providing a more holistic view of potential options and transition pathways. This paper outlines the concept of business modeling for use in Sustainable Urban Water Management (SUWM). A literature-based comparative assessment was undertaken for two cases: Melbourne, Australia and the Emscher Region, Germany. We demonstrate the practical relevance of the proposed framework for understanding enablers and inhibitors of change and identifying strategies for sustainability within the urban water sector.

This paper presents new evidence of the causal effect of air pollution on Australian health outcomes, using the Black Saturday bushfires (BSB) in 2009 as a natural experiment. This event was one of the largest bushfires in Australian history and emitted approximately four million tonnes of CO 2 into the atmosphere. We use data from the Household Income and Labour Dynamic Australia (HILDA) panel and compare the health status of individuals who were living in affected and unaffected regions before and after the event. Using a triple differences procedure, we further examine whether a difference in vulnerability to bushfire smoke exists comparing people living in urban or regional areas. We find that ambient air pollution had significant negative effects on health and that the magnitudes were actually larger for individuals residing in urban areas. • Examine the causal effect of air pollution on health from Australian bushfires. • Individuals exposed to pollutants had significantly poorer health outcomes. • Robust deficits appear across various objective and subjective health indicators. • People in major cities are more affected, likely from pre-existing pollutant exposure. • Results also vary by markers of socioeconomic status.

Background: International drug law enforcement agencies have identified an apparent rise in high level drug traffickers choosing to deal in multiple different drugs. It is hypothesised that this may be a "deliberate modus operandi" and that the formation of "portfolios of trades" may make such traffickers more profitable, harmful and resilient to changes in drug supply and policing. In this paper we provide the first exploration of the extent, nature and harms of poly-drug trafficking at Australian borders.Methods: Two different methods were used. First, we used Australian Federal Police (AFP) data on all commercial level seizures at the Australian border from 1999 to 2012 to identify the proportion of seizures that were poly-drug and trends over time. Second, we used unit-record data on a sub-set of 20 drug trafficking cases and linked-cases (defined as the original drug trafficking case and all other criminal cases that were connected via common offenders and/or suspects) to compare the profiles of poly-drug and mono-drug traffickers, including: the total weight and type of drug seized, the value of assets seized, and the level of involvement in other crime (such as money laundering and corruption).Results: Between 5% and 35% of commercial importations at the Australian border involved poly-drug trafficking. Poly-drug trafficking occurred in almost every year of analysis (1999-2012), but it increased only slightly over time. Compared to mono-drug traffickers poly-drug traffickers were characterised by: larger quantities of drugs seized, larger networks, longer criminal histories and more involvement in other types of serious crime.Conclusion: Some fears about poly-drug traffickers may have been overstated particularly about the inherent escalation of this form of trafficking. Nevertheless, this suggests poly-drug traffickers are likely to pose added risks to governments and law enforcement than mono-drug traffickers. They may necessitate different types of policy responses. [ABSTRACT FROM AUTHOR]

Ambient ultrafine particle number concentrations (PNC) have inhomogeneous spatio-temporal distributions and depend on a number of different urban factors, including background conditions and distant sources. This paper quantitatively compares exposure to ambient ultrafine particles at urban schools in two cities in developed countries, with high insolation climatic conditions, namely Brisbane (Australia) and Barcelona (Spain). The analysis used comprehensive indoor and outdoor air quality measurements at 25 schools in Brisbane and 39 schools in Barcelona. PNC modes were analysed with respect to ambient temperature, land use and urban characteristics, combined with the measured elemental carbon concentrations, NO x (Brisbane) and NO 2 (Barcelona). The trends and modes of the quantified weekday average daily cycles of ambient PNC exhibited significant differences between the two cities. PNC increases were observed during traffic rush hours in both cases. However, the mid-day peak was dominant in Brisbane schools and had the highest contribution to total PNC for both indoors and outdoors. In Barcelona, the contribution from traffic was highest for ambient PNC, while the mid-day peak had a slightly higher contribution for indoor concentrations. Analysis of the relationships between PNC and land use characteristics in Barcelona schools showed a moderate correlation with the percentage of road network area and an anti-correlation with the percentage of green area. No statistically significant correlations were found for Brisbane. Overall, despite many similarities between the two cities, school-based exposure patterns were different. The main source of ambient PNC at schools was shown to be traffic in Barcelona and mid-day new particle formation in Brisbane. The mid-day PNC peak in Brisbane could have been driven by the combined effect of background and meteorological conditions, as well as other local/distant sources. The results have implications for urban development, especially in terms of air quality mitigation and management at schools. [ABSTRACT FROM AUTHOR]

The concept of food security is often anchored in popular understandings of the challenge to produce and supply enough food. However, decades of policies for intensive agriculture have not alleviated hunger and malnutrition, with an absence of food security featuring in both economically developing and developed nations. Despite perceptions that the economic growth in advanced, capitalist societies will ensure freedom from hunger, this is not universal across so-called ‘wealthy nations’. To explore the dynamics of food security in economically developed countries, this paper considers institutional approaches to domestic food security primarily through responses to poverty and welfare entitlements, and, secondarily, through food relief. Through the lens of social entitlements to food and their formation under various expressions of welfare capitalism, we highlight how the specific institutional settings of two economically developed nations, Australia and Norway, respond to uncertain or insufficient access to food. Whilst Norway's political agenda on agricultural support, food pricing regulation and universal social security support offers a robust, although indirect, safety net in ensuring entitlements to food, Australia's neoliberal trajectory means that approaches to food security are ad hoc and rely on a combination of self-help, charitable and market responses. Despite its extensive food production Australia appears less capable of ensuring food security for all its inhabitants compared to the highly import-dependent Norway. [ABSTRACT FROM AUTHOR]

Estimates from the FAO Penman–Monteith (FAO-PM) and the standardized ASCE Penman–Monteith (ASCE-PM) hourly and daily reference evapotranspiration ( ET 0 ) equations were compared at daily scale, based on the hourly climate data collected from forty (40) geographically and climatologically diverse Automatic Weather Stations (AWS) across the Australian continent. These locations represent 23 agricultural irrigation areas in tropical, arid and temperate climates. The aims of this paper are to: compare the effects of different methods of estimating Clear-sky-radiation—( R so ); compare sum-of-hourly and daily ET 0 ; compare the results of aggregation of hourly ET 0 over 24 h compared with daylight hours; and examine the impact of seasonality and climate type. At selected AWS locations, the hourly ET 0 was calculated using the hourly FAO-PM and the ASCE-PM equations and then summed to derive daily ET 0 (reported as ET 0,soh ). This was compared against the daily ET 0 values, calculated using the corresponding daily equation (reported as ET 0,daily ). Using R so calculated following the “complex” approach improves the agreement between ET 0,soh and ET 0,daily of both hourly equations, compared with the “simple” approach. Better agreement between ET 0,soh and ET 0,daily estimates for the FAO-PM and ASCE-PM were found, when the hourly values are aggregated over 24 h rather than over daylight hours. The average ratio between ET 0,soh and ET 0,daily for the FAO-PM and ASCE-PM equations is 0.95 and 1.00, respectively. The range of the former is 0.90–0.98 and that of the latter is 0.96–1.04. There was very strong correlation between the two hourly equations at the daily time step: on average 0.997, with a range of 0.993–0.998. The results imply that the ASCE-PM hourly equation's daily ET 0 values are higher than those of FAO-PM, which can be explained by the difference in the treatment of surface resistances. Better agreements between ET 0,soh and ET 0,daily values for winter, spring and autumn were found for the FAO-PM version, while during summer, the ASCE-PM version showed better agreement. The best agreement between the hourly and daily results for the FAO-PM version was found in temperate climates and the ASCE-PM version showed best agreement in the tropical and arid climates.

The transfer of successful water market governance between international settings is increasingly attractive to policy makers under globalization. This paper tests lesson-drawing approaches to water market governance transfers using data from Spain and the Murray-Darling Basin, Australia. Spain is the blueprint country for water market adoption in Europe, while Australia is often presented as a world leader in innovative water market arrangements. A preliminary comparative analysis framework linking water market governance principles to observed institutional arrangements and outcomes is provided. Finally, some key lessons, problems and policy transfer potential to stimulate and enhance Spanish water markets from lesson-drawing approaches are drawn, with an emphasis on adaptive capacity as an institutional performance metric. We find that Spain's current water governance institutions and arrangements offer a solid platform for marketing reform, where some key adaptive capacity constraints are able to be addressed. The lessons drawn from this study highlight those areas of change which, while challenging, can be achieved in our view. • Lesson drawing methods offer a novel way to assess adaptive capacity in policy settings. • Australia's water markets provide a case study for comparing Spain's readiness for water market adoption. • Current institutional strengths and weaknesses are identified via the analysis. • Future adaptive capacity evaluation offers useful insights for water governors and policy-makers.

Abstract: The impact of widowhood on well-being has been well-documented, but to date has not focused extensively on the experience of older migrants who have aged in a foreign land. This study aimed to examine the well-being of older migrant widows from two groups in South Australia: British-born (n=61) and Greek-born (n=60) Australian migrants, who had been widowed, on average, 13years. All participants completed a self-report questionnaire in their preferred language. Three indicators of current well-being (self-rated health, depression and loneliness) as well as variables expected to differ cross-culturally, and potentially influence well-being (mourning rituals; continuing bonds to one's spouse; religiosity; social support) were measured. Greek-born widows displayed higher levels of mourning rituals, continuing bonds and religiosity than the British. Both groups perceived similarly high levels of familial social support. Greek widows also reported worse self-rated health, and increased symptoms of depression and loneliness compared to the British. This paper suggests that the detrimental impact of widowhood on well-being may be greater for non-English speaking migrants who are ageing outside of their country of origin, and who, despite residing in an English-speaking host country for several decades, have retained the linguistic, cultural and religious practices and traditions of their home country.

Abstract: The verification of the Comprehensive Nuclear-Test Ban Treaty (CTBT) relies amongst other things on the continuous and worldwide monitoring of radioxenon. The characterization of the existing and legitimate background, which is produced mainly by nuclear power plants and isotope production facilities, is of high interest to improve the capabilities of the monitoring network. However, the emissions from legitimate sources can usually only be estimated. For this paper historic source terms of 133Xe emissions from the isotope production facility at ANSTO, Sydney, Australia, have been made available in a daily resolution. Based on these high resolution data, different source term sets with weekly, monthly and yearly time resolution have been compiled. These different sets are then applied together with atmospheric transport modelling (ATM) to predict the concentration time series at two radioxenon monitoring stations. The results are compared with each other in order to examine the improvement of the prediction capability depending on the used time resolution of the most dominant source term in the region.

Abstract: The characteristics of dust particles deposited during the 2009 dust storm in the Gold Coast and Brisbane regions of Australia are discussed in this paper. The study outcomes provide important knowledge in relation to the potential impacts of dust storm related pollution on ecosystem health in the context that the frequency of dust storms is predicted to increase due to anthropogenic desert surface modifications and climate change impacts. The investigated dust storm contributed a large fraction of fine particles to the environment with an increased amount of total suspended solids, compared to dry deposition under ambient conditions. Although the dust storm passed over forested areas, the organic carbon content in the dust was relatively low. The primary metals present in the dust storm deposition were aluminium, iron and manganese, which are common soil minerals in Australia. The dust storm deposition did not contain significant loads of nickel, cadmium, copper and lead, which are commonly present in the urban environment. Furthermore, the comparison between the ambient and dust storm chromium and zinc loads suggested that these metals were contributed to the dust storm by local anthropogenic sources. The potential ecosystem health impacts of the 2009 dust storm include, increased fine solids deposition on ground surfaces resulting in an enhanced capacity to adsorb toxic pollutants as well as increased aluminium, iron and manganese loads. In contrast, the ecosystem health impacts related to organic carbon and other metals from dust storm atmospheric deposition are not considered to be significant. [Copyright &y& Elsevier]

Introduction: The absence of a clear model of care for services supporting pregnant women and mothers with substance use disorders has impeded opportunities to build an evidence base for the effectiveness of these services. Previous research has typically focused on the needs of pregnant women or mothers, as two distinct groups. This paper explores service providers' perceptions of key components of a model of care, extending from perinatal care to community-based support for up to 17 years post-delivery. A model of care is outlined and feasibility factors affecting implementation are highlighted.Methods: Qualitative methods were adopted as a first step to informing development of the model of care. Semi-structured in-depth interviews were conducted with thirty-eight staff providing a range of substance use in pregnancy and parenting services (SUPPS) in hospital and community-based agencies, in a metropolitan health district in Sydney, Australia. Interview data was entered into NVivo and analysed using constant comparative methods.Results: Guiding principles for the model of care included integrated care, harm reduction and person-centredness. Practice approaches integral to the model of care were promoting engagement with women, flexible service provision, trauma-informed care, and continuity of care. Feasibility factors influencing implementation of the model of care included fragmentation or siloing of the service network and workforce sustainability.Conclusions: A harm reduction approach was crucial for promoting engagement of women with SUPPS, particularly child protection services. A greater focus on providing ongoing community-based support for mothers also has the potential to achieve sustainable positive outcomes for women and children. Implementation of the SUPPS model of care could be undermined by threats to integration of service delivery and continuity of care. Further research is needed to explore consumer perspectives and inform the model of care as a framework for evaluation. [ABSTRACT FROM AUTHOR]

Disasters result in a range of impacts that significantly disrupt the health and wellbeing of those affected. After disasters, a hierarchy of affectedness may be explicitly or implicitly developed, where those affected are compared to each other, and to people affected by disasters in other locations. When an individual's sense of place is so significantly disrupted, these hierarchies are critical to improving the understanding of recovery trajectories, including mental health and well-being outcomes. These hierarchies have practical implications that influence the health outcomes of those affected, including eligibility for disaster aid, support services, and the way that people affected by disasters relate to others in their community. This paper expands the 'hierarchy of affectedness' concept coined by Andersen (2013) using findings from a qualitative study in Australia and New Zealand. Using a letter writing research method, twenty people who had been impacted by a range of disasters in different locations described what they considered helpful and unhelpful in the recovery. One emergent finding in this study was that hierarchies of affectedness are negotiated between impacted individuals, others affected in the same community, and outsiders. These hierarchies served as a helpful sense-making tool for some people impacted by disasters, while causing considerable secondary stress for others. Based on these findings, we offer an expansion to Andersen's existing model of hierarchies of affectedness in post-disaster settings. [ABSTRACT FROM AUTHOR]

Abstract: Ethnopharmacological significance: Although no known medicinal use for Pittosporum undulatum Vent. (Pittosporaceae) has been recorded, anecdotal evidence suggests that Australian Aboriginal people used Pittosporum angustifolium Lodd., G. Lodd. & W. Lodd. topically for eczema, pruritis or to induce lactation in mothers following child-birth and internally for coughs, colds or cramps. Aims of the study: Essential oil composition and bioactivity as well as differential solvent extract antimicrobial activity from Pittosporum angustifolium are investigated here first, to partially describe the composition of volatiles released in traditional applications of Pittosporum angustifolium for colds or as a lactagogue, and second to investigate antibacterial activity related to topical applications. Essential oils were also investigated from Pittosporum undulatum Vent., first to enhance essential oil data produced in previous studies, and second as a comparison to Pittosporum angustifolium. Materials and methods: Essential oils were hydrodistilled from fruit and leaves of both species using a modified approach to lessen the negative (frothing) effect of saponins. This was achieved by floating pumice or pearlite obsidian over the mixture to crush the suds formed while boiling. Essential oil extracts were analysed using GC–MS, quantified using GC-FID then screened for antimicrobial activity using a micro-titre plate broth dilution assay (MIC). Using dichloromethane, methanol, hexane and H2O as solvents, extracts were produced from leaves and fruit of Pittosporum angustifolium and screened for antimicrobial activity and qualitative phytochemical character. Results: Although the essential oil from leaves and fruit of Pittosporum undulatum demonstrated some component variation, the essential oil from fruits of Pittosporum angustifolium had major constituents that strongly varied according to the geographical location of collection, suggesting the existence of at least two chemotypes; one with high abundance of acetic acid decyl ester. This chemotype had high antimicrobial activity whilst the other chemotype had only moderate antimicrobial activity against the three microbial species investigated here. This result may support the occurrence of geographical specificity with regard to ethnopharmacological use. Antimicrobial activity screening of the solvent extracts from Pittosporum angustifolium revealed the leaves to be superior to fruit, with water being the most suitable extraction solvent. Conclusion: To the best of our knowledge, this study constitutes the first time essential oils, and solvent extracts from the fruits of Pittosporum angustifolium, have been examined employing comprehensive chemical and biological analysis. The essential oil composition presented in this paper, includes components with structural similarity as chemosemiotic compounds involved in mother–infant identification, which may have significance with regard to traditional applications as a lactagogue.

Abstract: A small corpus of student e-mail requests to academic staff in a British and an Australian university was collected in order to investigate the cross-cultural nature of Englishes in these requesting events. The notions of account and but-justification, together with the concepts of equity and equilibrium are used to explicate the distribution of various features associated with these requests. Results indicate that the British data orient to deferential dependence whereas the Australian data exhibit interdependent egalitarianism. Finally, the process of our analysis brings to light the fact that we ought to refine theory of obligation and this, we do. The overall claims of this paper are that the situated nature of student e-mail requests can have a great bearing on the discursive construction of student identities, that this has a bearing on how things get done, and that how things get done in different varieties of English merits further investigation.

Abstract: Hourly diffuse and direct solar irradiance data are required for weather files used in building energy simulation as well as Photovoltaic and solar thermal calculations. Access to up to date hourly observation data or satellite derived data for these parameters is currently only available for a selection of the Australian Bureau of Meteorology measurement locations. This study aims to investigate the accuracy of the methods used to estimate solar irradiance data from meteorological observations either in the absence of observed irradiance data or when irradiance observations are limited to global irradiance. In particular the focus of this paper is to investigate the accuracy of the process of coupling together global and direct/diffuse models. Five global and four diffuse/direct irradiance models are presented and compared to experimental data for four locations in Australia. In the case where experimental global irradiance data is available, values are used as input into various models to obtain diffuse and direct irradiance. In the absence of experimental irradiance data, the approach taken is to estimate global irradiance with a separate model and then feed these values into the diffuse/direct models. The errors associated with both of these approaches are investigated by comparing the modelled diffuse and direct irradiance values with known experimental data for four Australian locations over a period of a number of years. This study indicates that no single diffuse/direct irradiance model consistently outperformed the other models at estimating diffuse and direct irradiance whilst the Zhang and Huang global irradiance model with coefficients from Seo and Huang achieved the best estimates of global irradiance for the locations investigated. For the approach where global irradiance is estimated from a model, the resulting direct and diffuse data was found to differ significantly from the experimental data. The results indicate that the individual models that achieved the best estimates of global irradiance did not achieve the best estimates of diffuse and direct irradiance when coupled with a diffuse/direct model.

Abstract: Understanding the links between resource dependence and socio-economic wellbeing has long been a subject of interest amongst social scientists in North America. By contrast, relatively few Australian studies exist on this topic. This is despite the significant role of resource industries in shaping Australia''s economic and social geography. Where research has been undertaken it tends to focus on the experience of a single town or region. This paper presents a cross-sectional analysis of socio-economic performance across 33 small mining towns in Western Australia. We design and test a number of empirical models that are hypothesised to account for the variability in socio-economic performance across different resource industry contexts. The results of the analysis suggest that socio-economic wellbeing in these towns is highly variable, and contingent on a range of factors including the nature of the particular commodity, company structure, and location.

Abstract: The increasing global distribution of automobiles necessitates that the design of In-vehicle Information Systems (IVIS) is appropriate for the regions to which they are being exported. Differences between regions such as culture, environment and traffic context can influence the needs, usability and acceptance of IVIS. This paper describes two studies aimed at identifying regional differences in IVIS design needs and preferences across drivers from Australia and China to determine the impact of any differences on IVIS design. Using a questionnaire and interaction clinics, the influence of cultural values and driving patterns on drivers'' preferences for, and comprehension of, surface- and interaction-level aspects of IVIS interfaces was explored. Similarities and differences were found between the two regional groups in terms of preferences for IVIS input control types and labels and in the comprehension of IVIS functions. Specifically, Chinese drivers preferred symbols and Chinese characters over English words and were less successful (compared to Australians) at comprehending English abbreviations, particularly for complex IVIS functions. Implications in terms of the current trend to introduce Western-styled interfaces into other regions with little or no adaptation are discussed. [Copyright &y& Elsevier]

Abstract: Residential water consumption reductions resulting from water efficiency measures has received much research attention in recent years; however, research into the contribution of such measures in reducing hourly water demand and subsequent benefits to urban water service infrastructure efficiency is still in its infancy. In an attempt to address this issue, this study examined the degree of influence that differing water stock (e.g. taps, shower heads, clothes washers) efficiency in 191 households, participating in an Australian smart metering study, had on average day (AD) diurnal consumption patterns. Sub-sample clusters used for analysis were formed by a weighted household water stock efficiency star rating classification method. Results showed a statistically significant reduction in AD peak hour water consumption in households with stock of a higher composite star rating. Paired comparison between households with a composite efficiency rating greater than or equal to (≥) three stars and those of a composite rating less than (<) three stars showed a reduction in AD morning and evening peak hour consumption of 1.9L/p/h/d (15.35%) and 1.55L/p/h/d (16.64%), respectively. The paper concludes with a discussion on pipe network modelling and capital infrastructure efficiency implications derived from a better understanding of the likely reductions in AD peak hour water demand, due to residential water stock efficiency measures.

Abstract: The notion of developing resilience is becoming increasingly important as a way of responding to the social determinants of poor health, particularly in disadvantaged groups. It is hypothesized that resilient individuals and communities are able to ‘bounce back’ from the adversities they face. This paper explores the processes involved in building resilience as an outcome in relation to both quitting smoking and never smoking. The study involved 93 qualitative, oral-history interviews with participants from population groups with high and enduring smoking rates in Adelaide, Australia, and was essentially interested in how some people in these groups managed to quit or never start smoking in the face of adversities, in comparison to a group of smokers. Our key findings relate to what we call additive and subtractive resilience strategies, which focus on the practices, roles and activities that individuals either ‘took on’ or ‘left behind’ in order to quit smoking or remain abstinent. The theoretical lenses we use to understand these resilience strategies relate to biographical reinforcement and biographical reinvention, which situate the resilience strategies in a broader ‘project of the self’, often in relation to attempting to develop ‘healthy bodies’ and ‘healthy biographies’.

Background: Healthcare professionals (HCPs) provide an important point of contact through which people who use performance and image enhancing drugs (PIEDs) could access reliable information, advice, and interventions on a range of PIEDs, their use and related harms. However, HCPs often report difficulties engaging and building rapport with people who use PIEDs, and research suggests that they often lack specialist knowledge on these substances. Providing credible evidence-based resources to support HCPs is thus important. However, educational materials in this area are generally absent and the ones that exist have not been assessed for their utility in the HCP workforce. This paper examines the acceptability and usability of a PIED e-learning module (the Dopinglinkki e-module) targeted at HCPs in three EU Member States and Australia.Methods: A standardised two stage, mixed methodology was implemented. Stage 1 involved HCPs completing the e-module and completing an online survey (N = 77). Stage 2 involved conducting individual structured interviews with a subset of survey respondents (N = 37). Normalisation Process Theory and the Theoretical Framework of Acceptability were used as conceptual lenses.Findings: The e-module provided information that was perceived as useful for HCPs' current and future practice. However, several individual, organisational and societal level barriers were reported as preventing the e-module becoming an accepted and normalised aspect of the HCP workforce, including the need for up to date evidence, the time-consuming nature of completing the e-module, lack of organisational support, the use of over-complex language, and the module's potential to reinforce the stigmatisation of PIEDs.Conclusion: Providing credible evidence-based resources to support HCPs' knowledge development is important. Evidence-based and theory informed interventions are needed to equip HCPs with knowledge that can aid culturally sensitive interactions and effective engagement with people who use PIEDs. Reflecting on our study findings, it is important that the development of interventions should include the voices of both HCP and those using PIEDs, and that careful consideration is given to the various factors that may act as a barrier to effective implementation.

Unlabelled: Focused assessment with sonography for trauma (FAST) is a method for detecting haemoperitoneum in trauma patients on initial assessment in the Emergency Department. The aim of this paper is to present an Australian trauma centre's experience with FAST as a tool to screen for intraabdominal free fluid in patient's sustaining blunt truncal trauma. Method: Over a 63-month period, FAST scans were prospectively studied and compared with findings from a gold-standard investigation, either computed tomography (CT) or laparotomy. Results: 463 FAST results were collected prospectively from 463 patients. 53 scans were excluded due to lack of a corresponding confirmatory gold-standard test. Overall sensitivity, specificity, positive and negative predictive values for FAST in detecting free fluid were 78%, 97%, 91%, 93%, respectively. Analysis of the credentialed operators demonstrated an improvement in accuracy (sensitivity 80%, specificity 100%, positive predictive value 100%, negative predictive value 94%). These findings are comparable with documented international experience. Conclusion: The study demonstrates that the use of non-radiologist performed FAST in the detection of free fluid is safe and accurate within an Australian Trauma Centre. [ABSTRACT FROM AUTHOR]

Abstract: The provision of food causes environmental impacts that range from local through to global in scale. Organic farming, used in general here to mean farming practices with a greater emphasis on long-term sustainability, is one general approach to reduce these impacts. Whilst organic farming may be argued to be superior to conventional farming on the basis of local impacts, it is not often clear how organic farming performs relative to conventional farming in terms of wider, global impacts. In this paper we present a comparative assessment of on-farm and indirect energy consumption, land disturbance, water use, employment, and emissions of greenhouse gases, NO x , and SO2 of organic and conventional farming in Australia. A hybrid input-output-based life-cycle technique is employed in order to ensure a complete coverage of indirect requirements originating from all upstream production stages. Using data from a detailed survey of organic farms, the results show that direct energy use, energy related emissions, and greenhouse gas emissions are higher for the organic farming sample than for a comparable conventional farm sample. Direct water use and employment are significantly lower for the organic farms than for the conventional farms. However, the indirect contributions for all factors are much higher for the conventional farms, leading to their total impacts being substantially higher. This shows that indirect effects must be taken into account in the consideration of the environmental consequences of farming, in particular for energy use and greenhouse gas emissions, where the majority of impacts usually occur off-farm. Subject to yield uncertainties for organic versus conventional farming, from the sample here we can conclude that in addition to their local benefits, organic farming approaches can reduce the total water, energy and greenhouse gases involved in food production.
