Surveying the landscape five years on : An examination of how teachers, and the teaching of Australia's shared-history, is constructed within Australian academic literature
Description:
The purpose of this paper is to conduct a literature review of academic debates relating to the Australian Curriculum: History (ACH), in particular subjective constructions of teachers, and the teaching of Australian History and Aboriginal peoples' and Torres Strait Islanders’ histories. The literature reviewed from a socio-political lens, examines functions of power/knowledge operating in discourses of education to illuminate how teachers, Aboriginal peoples, and Torres Strait Islanders, take up and/or resist subjectivities constructing them. Drawing from the toolbox of post-structuralism, this literature review troubles the notion of the non-Indigenous perspective as dominant, and the teacher as an active, non-critical participant in the process.

Description:
The production of platform chemicals via carbon negative technologies will play an important role in global efforts to mitigate climate change. Succinic acid biorefineries are commercially mature carbon negative technologies that are plagued with large waste streams in the form of hemicellulose and gypsum. Here, a techno-economic analysis assesses the viability of a succinic acid biorefinery wherein hemicellulose is converted to acetic acid and dimethyl ether, and gypsum generation is avoided. Succinic acid is a feedstock for biodegradable plastics, acetic acid replaces petroleum-derived sources, and dimethyl ether is ideally suited as an energy storage vector. Our novel biorefinery concept presents an innovative integration of commercial technologies including water-splitting bipolar membrane electrodialysis for acid purification. The modelled multiproduct biorefinery (Multi Case)annually consumes 650,000 metric tonnes (t)of pulp logs, 135,000t of methanol, 1,700,000t of water, 42,000t of CO2 and 89 MW of electricity to produce 220,000t of succinic acid, 115,000t of acetic acid and 900t of dimethyl ether. All the parasitic electricity and heat duties are fulfilled within the biorefinery. Results show a CAPEX of AUD $635,000,000, OPEX of $180,000,000 and a succinic acid Minimum Selling Price of $990/t. Sensitivity and uncertainty analyses of the Multi Case biorefinery model show it is also resilient to price fluctuations.

Objectives: Incidence, prevalence, nature, severity and mechanisms of injury in elite female cricketers over two seasons from March 2014 to March 2016, inclusive. Design: Prospective cohort study. Methods: Injury data collected via Cricket Australia's Athlete Management System on all elite female players over two seasons were analysed. Profiles of the nature, anatomical location and mechanism of injuries were presented according to dominant player position. Injury incidence rates were calculated based on match playing hours. Results: There were 600 medical-attention injuries; with 77.7% players reporting ≥1 injury. There were 79.5% acute injuries compared to gradual onset injuries. Of the all medical-attention injuries, 20.2% led to time-loss; 34.7% were match-time-loss injuries. Match injury incidence was 424.7 injuries/10,000 h for all injuries and 79.3 injuries/10,000 h for time-loss injuries. Of all the injuries, 31.8% were muscle injuries and 16.0% joint sprains. Wrist and hand (19.8%), lumbar spine (16.5%) and knee (14.9%) injuries were the most common time-loss injuries. Six players sustained lumber spine bone stress injury that resulted in the most days missed due to injury (average 110.5 days/injury). Conclusions: There is a need to focus on specific injuries in female cricket, including thigh, wrist/hand and knee injuries because of their frequency, and lumbar spine injuries because of their severity.

Background: Anxiety has a powerful impact on learning due to activation of anxiety hormones, which target related receptors in the working memory. Experiential learning requires some degree of challenge and anxiety. Patient simulation, as a form of experiential learning, has been an integrated component of health professional education internationally over the last two decades, especially in undergraduate nursing education. Little information is available to determine if and how anxiety impacts nursing students’ clinical performance during simulation. Objectives: To investigate physiological and psychological anxiety during emergency scenarios in high-fidelity simulation and understand the effect of anxiety on clinical performance. Design: First2Act was the model for the simulation intervention. Second and third year undergraduate nursing students attended a two-hour simulation session and completed a demographic questionnaire plus pre-simulation self-reported psychological anxiety scale. A heart rate variability monitor was attached to each student's chest to measure heart rate variability (as a sign of anxiety) before engaging in two video-recorded simulated emergency scenarios (cardiac and respiratory) with a professional actor playing the patient. Performance was rated by a clinician followed by video-assisted debriefing. Finally, heart monitors were removed and students repeated self-reports of psychological anxiety. Results: Students’ psychological anxiety was high pre-simulation and remained high post-simulation. With regard to physiological anxiety, students were anxious at the start of the simulation but became more relaxed toward the end as they gained familiarly with the simulation environment (p < .007). Clinical performance increased significantly in the second scenario (p < .001). Factors found to positively affect clinical performance were length of enrolment in the nursing degree (p = .001), current employment in a nursing or allied healthcare field (p = .030), and previous emergency experience (p = .047). The relationship between physiological anxiety and clinical performance was statistically not significant, although there was an indication that low level anxiety led to optimal performance. Conclusion: High-fidelity patient simulation has the capacity to arouse novice nurses psychologically and physiologically while managing emergency situations. Indicative outcomes suggest that optimal performance was apparent when anxiety levels were low, indicating that they had received insufficient training to deal with situations that induced moderate to high anxiety levels.

Objectives: To determine the factors that influence physiotherapists’ choice to promote non-treatment physical activity to patients with musculoskeletal conditions. Design: Cross sectional survey. Methods: A national, online self report survey was targeted at Australian registered physiotherapists primarily treating patients with musculoskeletal conditions in private practice and outpatient settings. Likert scale questions were used to measure the factors influencing non-treatment physical activity promotion by physiotherapists. Results: Two hundred and sixteen full responses were received. Most (56.6%) respondents irregularly promoted non-treatment physical activity, whereas 43.4% always promoted non-treatment physical activity. Promotion of non-treatment physical activity was bivariately associated with respondents’ own physical activity level (x2[2] = 7.670, p = 0.022) and exercise science education (x2[1] = 4.613, p = 0.032). Multivariable analysis identified that Knowledge (knowing how to promote non-treatment physical activity) (OR = 1.60, 95%CI 1.026–2.502), Goals (other patient problems are more important) (OR = 0.62, 95%CI 0.424–0.897) and Innovation (compatibility of non-treatment physical activity promotion with the clinical environment) (OR = 1.75, 95%CI 1.027–2.985) were significantly and independently associated with non-treatment physical activity promotion. Conclusions: The majority of surveyed Australian physiotherapists irregularly promoted non-treatment physical activity. Lack of knowledge of how to promote non-treatment physical activity, prioritising other patient problems before non-treatment physical activity promotion and using promotion methods that are not compatible with current practice might reduce non-treatment physical activity promotion frequency by physiotherapists.
Description:
•Antenatal depression and cortisol may be important for developing infant stress regulation.•Hair cortisol concentrations are useful for measuring cortisol in pregnancy and the postpartum.•Maternal hair cortisol concentration across pregnancy was not associated with maternal depression.•Antenatal maternal depressive symptoms were both associated with lower infant cortisol at 12 months of age.•Lower infant cortisol reactivity was associated with higher infant externalizing symptoms. Understanding maternal mental health and cortisol regulation across pregnancy and the relationship to the development of the offspring’s stress regulation is critical to a range of health outcomes. The aim of this study was to investigate infant and maternal cortisol in women with depression. Data were obtained from 241 pregnant women within the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS), a selected pregnancy cohort study. Depression was measured using the Structured Clinical Interview for DSM-IV (SCID-IV) and repeat Edinburgh Postnatal Depression Scale (EPDS). Repeated measures of antidepressant use, stressful events, anxiety symptoms and maternal hair cortisol concentrations (HCC) and infant cortisol at 12 months postpartum in saliva and hair. Socio-emotional outcomes were measured at 12 months by maternal report on the Brief Infant and Toddler Socio-emotional Assessment (BITSEA). This study found that maternal depression was not associated with maternal HCC. Anxiety, stress and antidepressant use were not associated with maternal HCC. Independently, higher maternal 3rd trimester maternal depressive and anxiety symptoms were associated with lower infant cortisol response at 12 months of age. A higher number of postpartum stressful events was associated with lower infant cortisol response. Lower infant stress reactivity was associated with higher externalizing symptoms at 12 months of age. Future studies are required to understand implications for later mental health.

Online dating continues to grow in popularity and is associated with significant advantages; however, experiencing antisocial behaviours when online dating is a distinct possibility. The aim of the current study was to explore the utility of gender and the dark personality traits of narcissism, Machiavellianism, psychopathy, and sadism in predicting perpetration of a range of antisocial behaviours on the popular dating app Tinder. It was hypothesised that the male gender and higher scores on these personality traits would predict perpetration of antisocial behaviours on Tinder. Participants (N = 587; 21% men, 79% women) completed an online questionnaire, including the Antisocial Uses of Tinder® Scale which was constructed to measure a range of antisocial behaviours. Exploratory and Confirmatory factor analyses revealed three forms of antisocial behaviours (General, esteem, and sexual) which explained over half of the variance (58.99%) of variance in the Antisocial Uses of Tinder® measure. Regression analyses were run for each form of antisocial behaviour, and the predictive utility of gender and the dark traits were found to differ across the antisocial behaviours. Results of the current study support an individual differences approach to exploring antisocial behaviours online, particularly when online dating.
Description:
Background: Papers continue to be cited by authors even after they have been retracted. Retraction notices provide readers with information about retracted papers and may help minimise post-retraction citation. To date, a review of the quality of retraction notices in nursing science has not been reported. Design: An audit of retraction notices associated with 29 retracted manuscripts published in nursing science journals. Methods: Retraction notices were reviewed again using the Committee on Publication Ethics (COPE) guidelines. Results: In total, 28 retraction notices were retrieved and reviewed (one retracted paper did not have a retraction notice). Details of the retracted manuscripts were included in all reviewed notices and, in all but two, author names were reported. Details of the time between a paper being published and retracted were not reported and generally there was a little information in notices about how the retraction decisions were made. All retraction notices were freely available. Seven notices stated who had made the decision to retract. Twenty-two (77%) notices stated the reason for retraction. Notices were brief and contained factual information. The webpages of three retracted articles did not clearly indicate that the paper had been retracted. Conclusion: More detailed and informative retraction notices will inform readers and may help reduce post- retraction citation.
