- Description: Year nine students present a perpetual problem to schools and teachers alike. Typically aged 14 or 15 years old, year nines simultaneously experience puberty and adolescence. These converging life stages result in students’ whom teachers have described as being lost, disengaged and, more alarmingly, in never-never land. A largely unrecognised group of schools and teachers in Victoria, Australia, have chosen a novel approach to engaging year nine students through specific schooling structures and targeted curriculum—I term these approaches year nine programmes. These programmes typically involve different structures to mainstream schooling, including residential components, a greater focus on learning through experience and the use of an integrated curriculum. This paper shares the stories of six teachers who work on one such programme. The stories of the teachers are shared using phenomenological found poetry in search of the ‘essences’ of being a year nine teacher. Through the presentation of these essences, I argue that teachers of year nine programmes are required to have an accoutrement of skills, in addition to the skills needed by teachers who work in more mainstream settings. © 2023, The Author(s).

- Description: Consumers with co-existing mental health and drug/alcohol problems are exposed to more stigma than those with any other health problems. This scoping review aimed to systematically map the available literature regarding mental health nurses' attitudes, empathy, and caring efficacy towards consumers with a dual diagnosis. Twenty studies reported outcomes regarding nurse attitudes; however, none reported nurses' empathy or caring efficacy towards consumers with a dual diagnosis. Further research is required to advance the evidence on the impact of mental health nurses' attitudes, empathy and caring effectiveness, and the outcomes should lead to improved service delivery for consumers with a dual diagnosis. © 2020 Taylor & Francis Group, LLC.

Managing risk and enhancing corporate sustainability in the Australian extractive sector : An exploratory study of leading mining and oil & gas firms in Australia

- Description: Risk is an unavoidable issue in most activities of life, including business. Risk-management is increasingly a hot-button issue for stakeholders and the general public. As such, it is of rising importance in the high-risk extractive industries of mining and oil & gas. Specifically, risk-management can help firms reduce business failure-rates and enhance corporate sustainability. However, the integration of risk-management and corporate sustainability within planning, financing, and operations remains a key challenge for the sector. This research seeks to fill this gap by investigating and evaluating the current use of risk-management by extractive-sector firms to add value to stakeholders. Given that risk- management and its impact on corporate sustainability is enormous, this study will provide useful insights into the risk-management practices undertaken by extractive-sector firms in Australia and how cost-effective risk-management practices contribute to the overall enhancement of financial performance, stakeholder value and corporate sustainability of those firms. This study, after drawing data from Australia’s top 10 mining/metals firms and top 10 energy/utilities firms, uses: i) Questionnaires to give a background/context for the study, and ii) Interviews to further probe issues raised and gain a deeper understanding. The analysis in this study found that risk-management practices are: i) Perceived by management practices to contribute significantly to financial performance, stakeholder value and corporate sustainability of their firms ii) Very similar across mining firms and those in oil & gas, and iii) Too limited in application in the extractive-sector and should be extended beyond traditional hazards. Overall, it was found that risk-management systems appear to be comparable across Australia’s large mining firms and oil & gas firms. However, at a detailed level, these basic systems and structures of risk-management are adjusted and adapted to meet specific needs, corporate strategies, organisational objectives and environmental pressures. NOTE: At the request of the author, Chapters 2-12 and Appendix 7 have been removed.

- Description: Work exhibited at Counihan Gallery, Brunswick, Melbourne Inspired by an Australia Council residency in Rome in late 2009, Soul /Skin/Space explores the potential for bodily metaphors to be found in the physical environment - whether by overt reference, inferred likeness, or merely a trace left behind by the imprint of a hand or foot. In Rome there exists the incredibly powerful sense of human presence and a profound history in the depiction of the human form. The body is everywhere, both living and dead, flesh and stone, in the museums and galleries, on the streets, the aqueducts and fountains. The city itself is a living, breathing entity, an ancient being possessing the wisdom and knowledge borne out of three thousand years of experience. It has loved and lost, been abandoned and left others behind, lived through riches and poverty, triumphs, defeats and tragedies. Glimpses of faces and figures evoke memories of a once vigorous and youthful body now aged and weary. And monumental fragments of stone and marble are like broken bones and worn teeth, the relics of a once revered individual now almost reduced to dust.

- Description: Over the past three decades, tariff protection to farmers has fallen and partly been replaced by domestic support, whilst support for farmers in some emerging economies has grown. Against that backdrop, this paper provides new estimates of national economic impacts of global agricultural tariffs and domestic supports. Using the latest global economy-wide GTAP (Global Trade Analysis Project) model calibrated to 2017, we simulate (a) the removal of food and agricultural domestic supports and agri-food tariffs and (b) the removal also of tariffs on imports of non-agricultural goods. We find that agricultural support policies are still an important part of the global welfare cost of all goods' trade-restrictive policies (albeit only half as costly as in 2001), and tariffs still dominate the global welfare cost of all farm-support programs. That farm support could be re-instrumented to relieve natural resource and environmental stresses, boost food and nutrition security, and alleviate poverty and income inequality.

- Description: Background: Australian football is a popular sport in Australia, at both the community and elite levels. It is a high-speed contact sport with a higher incidence of medically treated injuries when compared with most other organized sports. Hamstring injuries, ligament injuries to the knee or ankle, hip/groin injuries and tendinopathies are particularly common and often result in considerable time lost from sport. Consequently, the prevention of lower limb injuries is a priority for both community and elite Australian football organizations. There is considerable literature available on exercise programmes aimed at reducing lower limb injuries in Australian football and other running-related sports. The quality and outcomes of these studies have varied considerably, but indicate that exercise protocols may be an effective means of preventing lower limb injuries. Despite this, there has been limited high-quality and systematic evaluation of these data. Objective: The aim of this literature review is to systematically evaluate the evidence about the benefits of lower limb injury prevention exercise protocols aimed at reducing the most common severe lower limb injuries in Australian football. Methods: The Cochrane Central Register of Controlled Trials, the Cochrane Bone Joint and Muscle Trauma Group Specialized Register, MEDLINE and other electronic databases were searched, from January 1990 to December 2010. Papers reporting the results of randomized controlled trials (RCTs), quasi-RCTs, cohort and case-control studies were extracted. Primary outcomes were injury reduction or risk factor identification and/or modification. Secondary outcomes were adherence to any trialled interventions, injury severity and adverse effects such as secondary injuries and muscle soreness. The methodological quality of extracted manuscripts was assessed and results were collated. Results: Forty-seven papers were identified and reviewed of which 18 related to hamstring injury, eight related to knee or ankle ligament injury, five related to tendon injury and four were hip or groin injury related. Another 12 papers targeted general lower limb injuries. Most (n = 27 [57 %]) were observational studies, investigating injury risk factors. Twenty reported the results of intervention trials. Of these, 15 were efficacy trials reporting the effects of an intervention in reducing injury rates, four were biomechanical interventions in which the impact of the intervention on a known injury risk factor was assessed and one reported changes in injury risk factors as well as injury rates. The strength of the evidence base for exercise programmes for lower limb injury prevention was found to be limited, primarily due to the research methods employed, low adherence to interventions by the study participants and a lack of statistical power. Limited evidence obtained from a small number of RCTs suggests that balance and control exercises might be efficacious in preventing ankle ligament injuries and a programme involving a combination of balance and control exercises, eccentric hamstring, plyometrics and strength exercises could be efficacious in preventing all lower limb injuries. Conclusions: Overall, the evidence for exercise programmes as an efficacious lower limb injury prevention strategy is predominantly restricted to studies addressing injury aetiology and mechanisms. The findings of this review highlight the need to develop and test interventions in well designed population-based trials with an emphasis on promoting intervention uptake and adherence and, hence, intervention effectiveness. The results of this review can inform the development of the components of a future lower limb injury prevention exercise protocol for community-level Australian football. © 2013 Springer International Publishing Switzerland.

- Description: Invasive mammalian predators have had a devastating effect on native species globally. The European red fox (Vulpes vulpes) is one such species where it has been introduced in Australia. A novel but unexplored tactic to reduce the impact of mammalian predators is the use of unrewarded prey odors to undermine the effectiveness of olfactory hunting behavior. To test the viability of unrewarded prey odors in an applied setting we investigated how foxes responded to the odors of three different prey species. We used the odors of two locally extinct native Australian marsupials; the eastern quoll (a smaller carnivore) and eastern bettong (a fungivore), and the European rabbit, an introduced herbivore. Conducting our research over a period of 3 weeks in a pastoral environment in South-eastern Australia, we used video observations of foxes' behaviors, as they encountered the different odors. We found a reduction in the number of fox visits to bettong odors in the third week. In contrast, we observed a sustained number of visits to rabbit odors. Foxes also spent more time investigating rabbit odors and displayed longer durations of vigilance behavior at quoll odors. Our results support the hypothesis that the exposure of wild foxes to unrewarded odors of novel prey species can reduce their interest in these odors, which might translate to a reduction in predation pressure. Our results also suggest, however, that olfactory pre-exposure may not be as effective at reducing fox interest in a competitor species' odor. © 2021 The Authors.

- Description: Background: Digital mental health (DMH) interventions incorporating elements that adapt to the evolving needs of consumers have the potential to further our understanding of the optimal intensity of therapist assistance and inform stepped-care models. Objective: The primary objective was to compare the efficacy of a transdiagnostic biopsychosocial DMH program, with or without therapist assistance for adults with subthreshold symptoms or a diagnosis of anxiety or depression. Methods: In a randomized adaptive clinical trial design, all participants had access to the DMH program, with eligibility to have their program augmented with therapist assistance determined by program engagement or symptom severity. Participants who met stepped-care criteria were randomized to have their treatment program augmented with either low-intensity (10 min/week of video chat support for 7 weeks) or high-intensity (50 min/week of video chat support for 7 weeks) therapist assistance. A total of 103 participants (mean age 34.17, SD 10.50 years) were assessed before (week 0), during (weeks 3 and 6), and after the intervention (week 9) and at the 3-month follow-up (week 21). The effects of 3 treatment conditions (DMH program only, DMH program+low-intensity therapist assistance, and DMH program+high-intensity therapist assistance) on changes in the 2 primary outcomes of anxiety (7-item Generalized Anxiety Disorder Scale [GAD-7]) and depression (9-item Patient Health Questionnaire [PHQ-9]) were assessed using the Cohen d, reliable change index, and mixed-effects linear regression analyses. Results: There were no substantial differences in the outcome measures among intervention conditions. However, there were significant time effect changes in most outcomes over time. All 3 intervention conditions demonstrated strong and significant treatment effect changes in GAD-7 and PHQ-9 scores, with absolute Cohen d values ranging from 0.82 to 1.79 (all P<.05). The mixed-effects models revealed that, in the Life Flex program–only condition at week 3, mean GAD-7 and PHQ-9 scores significantly decreased from baseline by 3.54 and 4.38 (all P<.001), respectively. At weeks 6, 9, and 21, GAD-7 and PHQ-9 scores significantly decreased from baseline by at least 6 and 7 points (all P<.001), respectively. Nonresponders at week 3 who were stepped up to therapist assistance increased program engagement and treatment response. At the postintervention time point and 3-month follow-up, 67% (44/65) and 69% (34/49) of the participants, respectively, no longer met diagnostic criteria for anxiety or depression. Conclusions: The findings highlight that early detection of low engagement and non–treatment response presents an opportunity to effectively intervene by incorporating an adaptive design. Although the study findings indicate that therapist assistance was no more effective than the DMH intervention program alone for reducing symptoms of anxiety or depression, the data highlight the potential influence of participant selection bias and participant preferences within stepped-care treatment models. ©Brooke Andrews, Britt Klein, Huy Van Nguyen, Denise Corboy, Suzanne McLaren, Shaun Watson.

Objective: The primary objective was to compare the efficacy of a transdiagnostic biopsychosocial DMH program, with or without therapist assistance for adults with subthreshold symptoms or a diagnosis of anxiety or depression. Methods: In a randomized adaptive clinical trial design, all participants had access to the DMH program, with eligibility to have their program augmented with therapist assistance determined by program engagement or symptom severity. Participants who met stepped-care criteria were randomized to have their treatment program augmented with either low-intensity (10 min/week of video chat support for 7 weeks) or high-intensity (50 min/week of video chat support for 7 weeks) therapist assistance. A total of 103 participants (mean age 34.17, SD 10.50 years) were assessed before (week 0), during (weeks 3 and 6), and after the intervention (week 9) and at the 3-month follow-up (week 21). The effects of 3 treatment conditions (DMH program only, DMH program+low-intensity therapist assistance, and DMH program+high-intensity therapist assistance) on changes in the 2 primary outcomes of anxiety (7-item Generalized Anxiety Disorder Scale [GAD-7]) and depression (9-item Patient Health Questionnaire [PHQ-9]) were assessed using the Cohen d, reliable change index, and mixed-effects linear regression analyses. Results: There were no substantial differences in the outcome measures among intervention conditions. However, there were significant time effect changes in most outcomes over time. All 3 intervention conditions demonstrated strong and significant treatment effect changes in GAD-7 and PHQ-9 scores, with absolute Cohen d values ranging from 0.82 to 1.79 (all P<.05). The mixed-effects models revealed that, in the Life Flex program–only condition at week 3, mean GAD-7 and PHQ-9 scores significantly decreased from baseline by 3.54 and 4.38 (all P<.001), respectively. At weeks 6, 9, and 21, GAD-7 and PHQ-9 scores significantly decreased from baseline by at least 6 and 7 points (all P<.001), respectively. Nonresponders at week 3 who were stepped up to therapist assistance increased program engagement and treatment response. At the postintervention time point and 3-month follow-up, 67% (44/65) and 69% (34/49) of the participants, respectively, no longer met diagnostic criteria for anxiety or depression. Conclusions: The findings highlight that early detection of low engagement and non–treatment response presents an opportunity to effectively intervene by incorporating an adaptive design. Although the study findings indicate that therapist assistance was no more effective than the DMH intervention program alone for reducing symptoms of anxiety or depression, the data highlight the potential influence of participant selection bias and participant preferences within stepped-care treatment models. ©Brooke Andrews, Britt Klein, Huy Van Nguyen, Denise Corboy, Suzanne McLaren, Shaun Watson.

- Description: Objective: This qualitative study investigated therapist training experiences, elements of skill acquisition, and barriers and facilitators associated with conducting assessments, and the delivery of low- and high-intensity therapist assistance delivered via video chat technology, adjunctive to a transdiagnostic digital mental health intervention programme for anxiety and depression. Methodology: In total, 34 semistructured interviews were conducted with 20 therapists. Twenty interviews explored experiences of training to administer a clinical assessment tool, and 14 additional interviews explored training experiences of delivering low- and high-intensity therapist assistance via video chat technology. Results: Reflexive thematic analysis identified three themes: video chat skill acquisition, competencies transferrable to video chat and video chat service quality. Training and supervision were identified as important to scaffold skill development, and therapists described surprise that their skill set was transferrable to video chat. The most cited barrier to the adoption of video chat was the management of risk and distress, along with environmental suitability. Frequently cited facilitators to the adoption of video chat included stable Internet connection, protocols and resources. Conclusion: The benefits of video chat technology and digital mental health interventions can be maximised through the expansion and integration of training into existing teaching curricula. If therapists are familiarised and competent to deliver mental health services via the Internet, as well as in person, the future adoption of blended and stepped-care models is likely to be increased. © 2023 The Authors.

- Description: Background: Anxiety and depression are leading causes of disease worldwide, requiring timely access to evidence-based treatment. Digital mental health (dMH) interventions increase accessibility to evidence-based psychological services delivered in a variety of web-based formats (eg, self-help and therapist-assisted interventions). Robust and rigorous studies of adaptive web-based intervention designs are scarce. No identified randomized clinical trial has investigated the efficacy of a 2-stage adaptive design, whereby the program-only condition or no support dMH treatment program is augmented by either low or high therapist assistance, if a participant does not improve or engage in the program-only condition. Objective: The primary objective is to assess whether low or high therapist-assisted support delivered via video chat is more effective in reducing anxiety and depressive symptoms compared with a dMH program–only condition. The secondary objective is to evaluate the role of motivation; self-efficacy; and preferences in participant engagement, adherence, and clinical outcomes (anxiety and depression symptoms) among the 3 treatment conditions (program only, low-intensity therapist assistance, and high-intensity therapist assistance). A mixed methods analysis of factors affecting participant attrition, participant reasons for nonengagement and withdrawal, and therapist training and implementation of dMH interventions will be completed. Qualitative data regarding participant and therapist experiences and satisfaction with video chat assessment and treatment will also be analyzed. Methods: Australian adults (N=137) with symptoms or a diagnosis of anxiety or depression will be screened for eligibility and given access to the 8-module Life Flex dMH treatment program. On day 15, participants who meet the augmentation criteria will be stepped up via block randomization to receive therapist assistance delivered via video chat for either 10 minutes (low intensity) or 50 minutes (high intensity) per week. This adaptive trial will implement a mixed methods design, with outcomes assessed before the intervention (week 0), during the intervention (weeks 3 and 6), after the intervention (week 9), and at the 3-month follow-up (week 21). Results: The primary outcome measures are for anxiety (Generalized Anxiety Disorder–7) and depression severity (Patient Health Questionnaire–9). Measures of working alliance, health status, health resources, preferences, self-efficacy, and motivation will be used for secondary outcomes. Qualitative methods will be used to explore participant and therapist experiences of video chat assessment and treatment, participant reasons for withdrawal and nonengagement, and therapist training and implementation experiences. Data collection commenced in November 2020 and was completed at the end of March 2022. Conclusions: This is the first mixed methods adaptive trial to explore the comparative efficacy of different intensity levels of self-help and a therapist-assisted dMH intervention program delivered via video chat for adults with anxiety or depression. Anticipated results may have implications for the implementation of dMH interventions. © Brooke Andrews, Britt Klein, Suzanne McLaren, Shaun Watson, Denise Corboy.

- Description: The HLA community currently utilizes federate compliance testing to give federate users confidence that the way in which a federate operates is correct. This compliance testing currently involves a series of manually organized software-based tests and is performed prior to run-time. This does not cover the possibility of noncompliance-tested modifications before actual deployment. Addressing these issues could see the development of compliance testing for HLA federates which is automatically performed during federate execution. The goal of compliance testing---to ensure that HLA federates conform to the HLA standards---has strong similarities with the goals of computer security. This paper critically discusses the concept of automated federate compliance testing, its ability to cover multiple federate versions, and its application to HLA security

- Description: In vitro and in vivo studies of the activity of Phaleria macrocarpa Boerl (Thymelaeaceae) leaves against the therapeutic target for hypercholesterolemia were done using the HDL receptor (SR-BI) and hypercholesterolemia-induced Sprague Dawley rats. The in vitro study showed that the active fraction (CF6) obtained from the ethyl acetate extract (EMD) and its component 2',6',4-trihydroxy-4'-methoxybenzophenone increased the SR-BI expression by 95% and 60%, respectively. The in vivo study has proven the effect of EMD at 0.5 g/kgbw dosage in reducing the total cholesterol level by 224.9% and increasing the HDL cholesterol level by 157% compared to the cholesterol group. In the toxicity study, serum glutamate oxalate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) activity were observed to be at normal levels. The liver histology also proved no toxicity and abnormalities in any of the treatment groups, so it can be categorized as non-toxic to the rat liver. The findings taken together show that P. macrocarpa leaves are safe and suitable as an alternative control and prevention treatment for hypercholesterolemia in Sprague Dawley rats. ©2015 by the authors; licensee MDPI.
