Accessible and equitable education is a national priority recently highlighted by the Indian and Australian Governments. New developments in web-based architecture allow augmented reality (AR) lessons to be delivered via smartphone. Although educational technology is commonplace in the Australian curriculum, it is unclear if Indian tertiary students would be welcoming towards web-based mobile learning due to a historically slower uptake and only recent availability of connected devices in their educational system. This study evaluated feedback after using a web-deployed AR smartphone-based application across both Australia (70 participants) and India (100 participants) to see if this technology can assist in capacity building on a global scale. From thematic analyses on the provided feedback, it was identified that Australian students were more focused on the benefits received from the educational technology. In contrast, Indian students were far less critical of the embedded lesson, and more interested in the prospect of introducing the specific technology into their curricula. The data suggests that a rollout of web-based mobile AR for learning in countries more digitally-native should likely prioritise the content within it. Alternatively, for countries recently-introduced to educational technology, such as India, a rollout should focus on embedding the technology itself first. Although there is a risk of learners being distracted by the technology, smartphone web-based AR presents an excellent option to equitably provide a modern, innovative intervention, regardless of wealth, location, or status.

Background: Osteoporotic fractures signal severely compromised bone strength and are associated with a greatly increased risk of refracture. Despite the availability of effective and safe medications that reduce fracture risk, 70–80% of patients are inadequately investigated or treated for osteoporosis following an initial fracture, constituting a significant 'osteoporosis care gap'. Optimal methods of bridging this gap with primary care at the forefront of secondary fracture prevention remain undetermined. This protocol describes a cluster randomised controlled trial to evaluate the effectiveness of a novel integrated model of secondary fracture prevention and management in primary care. Methods: The cluster randomised controlled trial involves multiple branches of a community-based radiology provider (CRP), a hospital-based secondary fracture prevention program (SFPP) and numerous primary care practices in metropolitan Sydney that refer to either the CRP or SFPP. Using natural language processing tools, patients diagnosed with a potential osteoporotic fracture will be identified by automatically screening radiology reports generated at the CRP or SFPP. The primary care practices that these patients attend will be randomised (1:1) to either the intervention or usual care. The intervention consists of (i) electronic and fax alerts informing the practice/primary care physician that their patient has been diagnosed with a potential osteoporotic fracture; (ii) provision of osteoporosis management guidelines and (iii) follow-up surveys at 4 weeks and 6 months. Practices in the usual care (control) group will receive no alerts and provide usual care. The primary outcome is the proportion of patients undergoing a bone density scan and/or filling a prescription for osteo-protective pharmacotherapy within 3 months of the initial diagnostic imaging report. Secondary outcomes are the proportion of patients: (i) undergoing an osteoporosis-related blood test within 3 months of the initial diagnostic imaging report; (ii) initiated on a chronic disease management plan within 3 months of the diagnostic report, and (iii) filling a second prescription for osteo-protective pharmacotherapy within 9 months post initial diagnostic imaging report. Outcomes will be obtained through de-identified linked data from Medical Benefits Schedule and Pharmaceutical Benefits Scheme held by the Australian Institute of Health and Welfare. Discussion: This is the first randomised trial to integrate case-detection of potential osteoporotic fractures in a hospital and community setting with direct alerts to the patient's primary care provider. This study will determine whether such an intervention is effective in improving investigation and/or treatment rates of osteoporosis in patients with a potential osteoporotic fracture. Trial registration: This study is registered with the Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12623000658617p. [ABSTRACT FROM AUTHOR]

Pulmonary nodules are common incidental findings requiring surveillance. Follow‐up recommendations vary depending on risk factors, size and solid or subsolid characteristics. This review aimed to evaluate the prevalence of clinically significant nodules detected on noncancer‐dedicated imaging and the prevalence of part‐solid and ground‐glass nodules. We conducted a systematic search of literature and screened texts for eligibility. Clinically significant nodules were noncalcified nodules >4–6 mm. Prevalence estimates were calculated for all studies and risk of bias was assessed by one reviewer. Twenty‐four studies were included, with a total of 30 887 participants, and 21 studies were cross‐sectional in design. Twenty‐two studies used computed tomography (CT) imaging with cardiac‐related CT being the most frequent. Prevalence of significant nodules was highest in studies with large field of view of the chest and low size thresholds for reporting nodules. The prevalence of part‐solid and ground‐glass nodules was only described in two cardiac‐related CT studies. The overall risk of bias was low in seven studies and moderate in 17 studies. While current literature frequently reports incidental nodules on cardiovascular‐related CT, there is minimal reporting of subsolid characteristics. Unclear quantification of smoking history and heterogeneity of imaging protocol also limits reliable evaluation of nodule prevalence in nonscreening cohorts. [ABSTRACT FROM AUTHOR]

Conventional, teacher-centred classroom activities are prominent in Vietnam where educators are familiar with a one-way flow of information and using limited resources for their practice, whilst a culture of creativity in the classroom is often ignored. Vietnamese educators face a huge challenge, motivating passive learners to be more creative and active learners as society responds to rapid changes in technologies. This article suggests that a flipping structure that incorporates a design thinking approach paves the way for course designers to assist passive learners to become more active in their learning processes. An undergraduate course was redesigned and delivered in a flipped classroom design, aiming at nurturing active learning among students. Quantitative findings highlighted that there was an improvement in student's engagement, including intellectual engagement and attendance, and that overall student satisfaction improved.

While intellectual property laws protect rights holders from infringement of their intellectual property, these laws also protect against abuse of those rights where rights holders unjustifiably threaten competitors with infringement proceedings. The introduction of additional damages for flagrant unjustified threats under the recent Intellectual Property Laws Amendment (Productivity Commission Response Part 1 and Other Measures) Act 2018 (Cth) may benefit an alleged infringer who is not found to have infringed a valid patent. In particular, new section 128(1A) to the Patents Act 1990 allows additional damages to be awarded against a person for making blatant unjustified threats of infringing a patent. In cases where it is difficult to determine the loss and ordinary damages cannot be awarded, a court could award a nominal amount in compensation, but the difficulty lies in whether, in some cases, damages can be awarded at all. This raises the need to consider other legal avenues to address the issue of unjustified threats relating to patented inventions. In this paper we have identified four such other legal avenues being: specific provisions of the Australian Consumer Law; the misuse of market power provisions in s 46 Competition and Consumer Act 2010 (Cth); the duty of care and diligence in s 180 Corporations Act 2001 (Cth); and the law of joint tortfeasorship. Each of these potential legal solutions will be examined in turn however a comparison of remedies, or interactions with the laws of evidence, and exploration of costs are beyond the scope of this analysis. Further while we acknowledge that other Australian legislation provides a cause of action arising from the making of unjustifiable threats, such as in the Copyright Act 1968, the Trade Marks Act 1995, the Designs Act 2003 and the Circuit Layouts Act 1986, this paper is focused on the Patents Act 1990 only.

Increasing numbers of international students studying health sciences in Australia necessitates research into appropriate ways to support cultural diversity in teaching. International students commonly face problems in adapting to culturally different education and health care systems and this complicates the development of the discipline specific skills that they have come to learn. This paper presents a curriculum review of a course, titled "Language and Communication in Physiotherapy" in a Physiotherapy Masters Program for international students. The aim was to redevelop the course to better align with principles of internationalisation of the curriculum, seeking to ensure that the course did not follow a deficit model of meeting international students' needs. A philosophical shift was considered by staff and led to a revision of course aims, content and assessment. Instead of viewing students as having "gaps" in understanding or skills that needed to be patched up in order to fit Australian norms, it was considered that the chief aim of the course was to foster the development of cultural competence. Course changes made as an outcome of the review were evaluated and the outcomes suggest that some of the changes were successful, whilst others require further development. The process of reflective practice followed in undertaking this review was helpful not only in devising course content and assessment changes useful to students' learning, but also in advancing the cultural competence of teachers involved in the course.

Our objective was to evaluate the association of antioxidant intake and the inflammatory potential of the diet with functional decline in older men. A diet history questionnaire was used to collect dietary intake data from men aged ≥ 75 years (n 794) participating in the Concord Health and Aging in Men Project cohort study. Intake of vitamins A, C, E and Zn were compared with the Australian Nutrient Reference Values to determine adequacy. The Energy-adjusted Dietary Inflammatory Index (E-DIITM) was used to assess the inflammatory potential of the diet. Physical performance data were collected via handgrip strength and walking speed tests, and activities of daily living (ADL) and instrumental activities of daily living (IADL) questionnaires, at baseline and 3-year follow-up (n 616). Logistic regression analysis was used to identify associations between diet and incident poor physical function and disability. Both poor antioxidant intake and high E-DII scores at baseline were significantly associated with poor grip strength and ADL disability at 3-year follow-up. No significant associations with walking speed or IADL disability were observed. Individual micronutrient analysis revealed a significant association between the lowest two quartiles of vitamin C intake and poor grip strength. The lowest quartiles of intake for vitamins A, C, E and Zn were significantly associated with incident ADL disability. The study observed that poor antioxidant and anti-inflammatory food intake were associated with odds of developing disability and declining muscle strength in older men. Further interventional research is necessary to clarify the causality of these associations. [ABSTRACT FROM AUTHOR]

Introduction: This manuscript delves into the intricate connection between climate change and Indigenous mental health in Australia, with a focus on the aftermath of the defeat of the 'Voice' referendum. Climate change, recognized for its broad impact on mental health determinants, poses heightened risks to vulnerable communities, including Indigenous populations. The defeat of 'The Voice' referendum adds complexity, highlighting concerns about the lack of meaningful rights for the First Peoples of Australia. The bushfires further underscore ecological consequences, affecting Indigenous ecosystems and intensifying existing environmental challenges. Climate change exacerbates existing health challenges for Indigenous peoples, introducing new issues like ecological sorrow and anxiety. Methodology: The manuscript advocates for prioritized research in Indigenous communities to explore the link between climate change and mental health. It emphasizes interdisciplinary and collaborative research, giving voice to those directly affected by climate change. The lack of trust between Indigenous populations and authorities, along with the implications on self-determination, is crucial research focus. Results: Renewable energy emerges as a potential solution deeply ingrained in Indigenous practices. The manuscript discusses challenges in achieving eco-friendly resettlement, emphasizing collaboration difficulties between the government and remote communities. The indigenous worldview, with its interconnectedness, is crucial for sustainable strategies. Discussion and Future Directions: Indigenous perspectives on planetary health are crucial, emphasizing the importance of Indigenous knowledge in shaping effective climate policies. The manuscript stresses dialogues between policymakers and Indigenous elders for formulating respectful land laws. It calls for global attention to the role of Indigenous peoples as biodiversity caretakers and urges recognition of their knowledge in climate change. Future directions include data collection for ecosystem protection, improving mental health outcomes post-climate events, and supporting impacted communities. Mental health care approaches in remote communities and practitioner training for climate-related issues are emphasized. The manuscript calls for increased funding for interdisciplinary research to understand the long-term impact of climate change on mental health, especially among vulnerable populations.

Pigeon circovirus (PiCV) is considered to be genetically diverse, with a relatively small circular single-stranded DNA genome of 2 kb that encodes for a capsid protein (Cap) and a replication initiator protein (Rep). Australasia is known to be the origin of diverse species of the Order Columbiformes, but limited data on the PiCV genome sequence has hindered phylogeographic studies in this species. To fill this gap, this study was conducted to investigate PiCV in 118 characteristic samples from different birds across Australia using PCR and sequencing. Eighteen partial PiCV Rep sequences and one complete PiCV genome sequence were recovered from reservoir and aberrant hosts. Phylogenetic analyses revealed that PiCV circulating in Australia was scattered across three different subclades. Importantly, one subclade dominated within the PiCV sequenced from Australia and Poland, whereas other PiCV sequenced in this study were more closely related to the PiCV sequenced from China, USA and Japan. In addition, PiCV Rep sequences obtained from clinically affected plumed whistling duck, blue billed duck and Australian magpie demonstrated natural spillover of PiCV unveiled host generalist characteristics of the pigeon circovirus. These findings indicate that PiCV genomes circulating in Australia lack host adapted population structure but demonstrate natural spillover infection. [ABSTRACT FROM AUTHOR]

This study considers the career identities of Vietnamese students studying at an offshore (Australian) university in Vietnam. The students had completed the first module of a new career development learning program called Career Passport. As part of the program, students were required to write a narrative on their 'career story' to reflect on their experiences and synthesise their learning. The study drew on a social constructionist and narrative psychology approach to explore the major influences on the career identity that emerged from the students' narratives. The strongest influence on the students' career identities and career decision-making was family, which is in accordance with the collectivist cultural values of Vietnam. Somewhat less expected was the effect of various media, such as film and television. Despite the influence of family, the narratives reflect a strong desire to meet individual values, needs and interests in what the students would like their future careers to look like. The latter two findings perhaps indicate that Vietnamese students at an international university are more influenced by Western values and expectations of 'career' than their counterparts who study at domestic universities.

INTRODUCTION Despite that the smoking prevalence has considerably declined in Australia after successful public health strategies over many decades, smoking is still the leading cause of preventable diseases and death in Australia. These declines have not occurred consistently across all geographical-demographic domains. In order to provide an evidence base for monitoring the trend towards the goal of reducing smoking across all domains in Australia, this study aims to estimate trends of smoking prevalence for small domains cross-classified by seven age groups (18-24, 25-29, 30-39, 40-49, 50-59, 60-69, and ≥70 years), two genders, and eight states and territories over twenty years (2001-2021). METHODS Direct estimates of smoking prevalence for the target small domains were calculated from the micro-data of the Australian National Health Surveys conducted in seven rounds during 2001-2021. The obtained direct estimates were then used as input for developing time-series models expressed in a hierarchical Bayesian structure as a form of small-area estimation. The developed models borrow cross-sectional, temporal, and spatial strength in such a way that they can interpolate smoking levels in the non-survey years for all detailed level small domains. Smoothed trends of smoking prevalence for higher aggregation levels are obtained by aggregation of the detailed level trend predictions. RESULTS Model-based small area estimators provide consistent and reasonable smoothed trends at both detailed and higher aggregation levels. Results show that the national-level trend exhibits a steeper linear decline over the study period, from 24% in 2001 to 12% in 2021, with a considerable gender difference of around 5% over the period, with males reporting a higher prevalence. Improved model-based estimates at the state level and by age also show steady declines in trends except for the Northern Territory (still above 20%) and older age groups 60-69 and ≥70 years (declining trends remain stable after 2012). CONCLUSIONS The findings of the study identify the geographical-demographic groups that had poor improvement over the period 2001-2021, and are still behind the target of achieving lower smoking prevalence. These, in turn, will help health researchers and policymakers deliver targeted programs to the most vulnerable, enabling the nation to meet its health goals in a timely way. [ABSTRACT FROM AUTHOR]

Columbid alphaherpesvirus 1 (CoHV1) is associated with oral or upper respiratory tract lesions, encephalitis, and occasional fatal systemic disease in naive or immunosuppressed pigeons. Clinical disease is often reported with CoHV1 and coinfecting viruses, including pigeon circovirus (PiCV), which may cause host immunosuppression and augment lesion development. A natural outbreak of CoHV1 and PiCV coinfection occurred in a flock of 60 racing rock pigeons (Columba livia), in which 4 pigeons succumbed within 7 d of clinical onset. Lesions included suppurative stomatitis, pharyngitis, cloacitis, meningitis, and tympanitis, with eosinophilic intranuclear inclusion bodies consistent with herpesviral infection. In addition, large numbers of botryoid intracytoplasmic inclusion bodies were present in the skin, oral mucosa, and bursa of Fabricius, suggestive of circoviral infection, which was confirmed by immunohistochemistry. The concurrent viral load of CoHV1 and PiCV was high in liver, oropharynx, and bursa of Fabricius. We found PiCV in oro-cloacal swabs from 44 of 46 additional birds of variable clinical status, PiCV alone in 23 birds, and coinfection with CoHV1 in 21 birds. Viral copy numbers were significantly higher (p < 0.0001) for both viruses in clinically affected pigeons than in subclinical qPCR-positive birds. The CoHV1-induced lesions might have been exacerbated by concomitant PiCV infection. [ABSTRACT FROM AUTHOR]

Research has largely focused on the psychological consequences of refugee trauma exposure, but refugees living with visa insecurity face an uncertain future that also adversely affects psychological functioning and self-determination. This study aimed to examine how refugee visa insecurity affects the functional brain. We measured resting state brain activity via fMRI in 47 refugees with insecure visas (i.e. temporary visa status) and 52 refugees with secure visas (i.e. permanent visa status) residing in Australia, matched on key demographic, trauma exposure and psychopathology. Data analysis comprised independent components analysis to identify active networks and dynamic functional causal modelling tested visa security group differences in network connectivity. We found that visa insecurity specifically affected sub-systems within the default mode network (DMN) – an intrinsic network subserving self-referential processes and mental simulations about the future. The insecure visa group showed less spectral power in the low frequency band in the anterior ventromedial DMN, and reduced activity in the posterior frontal DMN, compared to the secure visa group. Using functional dynamic causal modelling, we observed positive coupling between the anterior and posterior midline DMN hubs in the secure visa group, while the insecure visa group displayed negative coupling that correlated with self-reported fear of future deportation. Living with visa-related uncertainty appears to undermine synchrony between anterior-posterior midline components of the DMN responsible for governing the construction of the self and making mental representations of the future. This could represent a neural signature of refugee visa insecurity, which is marked by a perception of living in limbo and a truncated sense of the future. Refugee visa insecurity disrupts default mode network (DMN) connectivity – a core network that supports the internal construction of the self. Refugees living with insecure visa status showed decreased connectivity in the DMN and more negative coupling between midline anterior–posterior hubs of the DMN, compared to refugees living with secure visas. Diminished DMN connectivity may represent a neural basis for the psychological effects of refugee visa insecurity, which is associated with prolonged uncertainty regarding the future self and increased risk for psychological distress.

Heavy rainfall and precipitation play a massive role in shaping the socio-agricultural landscape of a country. Being one of the key indicators of climate change, natural disasters, and of the general topology of a region, rainfall prediction is a gift of estimation that can be used for multiple beneficial causes. Machine learning has an impressive repertoire in aiding prediction and estimation of rainfall. This paper aims to find the effect of ensemble learning, a subset of machine learning, on a rainfall prediction dataset, to increase the predictability of the models used. The classification models used in this paper were tested once individually, and then with applied ensemble techniques like bagging and boosting, on a rainfall dataset based in Australia. The objective of this paper is to demonstrate a reduction in bias and variance via ensemble learning techniques while also analyzing the increase or decrease in the aforementioned metrics. The study shows an overall reduction in bias by an average of 6% using boosting, and an average reduction in variance by 13.6%. Model performance was observed to become more generalized by lowering the false negative rate by an average of more than 20%. The techniques explored in this paper can be further utilized to improve model performance even further via hyper-parameter tuning. [ABSTRACT FROM AUTHOR]

Introduction and hypothesis: Vaginal pessaries are a low-cost, effective treatment for pelvic organ prolapse (POP) and an alternative to surgery. Whilst traditionally pessary management (PM) has been provided by medical professionals, particularly gynaecologists, recent international studies found other professionals, including physiotherapists and nurses, may be involved. It is unknown which health care practitioners (HCPs) provide PM for POP in Australia or the distribution of services. Methods: In a cross-sectional study design, a self-reported electronic survey investigated Australian HCPs providing PM for POP. Purposive and snowball sampling targeted HCPs, professional organisations and health care facilities. Descriptive statistics described PM in relation to HCP professional profile, PM provision and geographical location. Results: There were 536 respondents (324 physiotherapists, 148 specialists, 33 general practitioners (GPs) and 31 nurses providing PM. Most worked within metropolitan regions (n = 332, 64%), 140 (27%) in rural, 108 (21%) in regional and 10 (2%) in remote areas. Most worked privately (n = 418, 85%), 153 (46%) worked publicly and 85 (17%) in both. Ring pessaries were most commonly used, followed by cube and Gellhorn. HCPs reported variable training in PM, and 336 (69%) had no mandatory workplace competency standard; however, 324 (67%) wanted further training. Women travelled long distances to access services. Conclusions: Doctors, nurses and physiotherapists provided PM in Australia. HCPs had variable training and experience in PM, with rural and remote HCPs particularly wanting further training. This study highlights the need for accessible PM services, standardised and competency-based training for HCPs, and governance structures ensuring safe care. [ABSTRACT FROM AUTHOR]

Objective: In Queensland, where a person experiences a major disturbance in their mental capacity, and is at risk of serious harm to self and others, an emergency examination authority (EEA) authorises Queensland Police Service (QPS) and Queensland Ambulance Service (QAS) to detain and transport the person to an ED. In the ED, further detention for up to 12 h is authorised to allow the examination to be completed. Little published information describes these critical patient encounters. Methods: Queensland's Public Health Act (2005), amended in 2017, mandates the use of the approved EEA form. Data were extracted from a convenience sample of 942 EEAs including: (i) patient age, sex, address; (ii) free text descriptions by QPS and QAS officers of the person's behaviour and any serious risk of harm requiring urgent care; (iii) time examination period commenced; and (iv) outcome upon examination. Results: Of 942 EEA forms, 640 (68%) were retrieved at three 'larger central' hospitals and 302 (32%) at two 'smaller regional' hospitals in non‐metropolitan Queensland. QPS initiated 342 (36%) and QAS 600 (64%) EEAs for 486 (52%) males, 453 (48%) females and two intersexes (<1%), aged from 9 to 85 years (median 29 years, 17% aged <18 years). EEAs commonly occurred on weekends (32%) and between 2300 and midnight (8%), characterised by 'drug and/or alcohol issues' (53%), 'self‐harm' (40%), 'patient aggression' (25%) and multiple prior EEAs (23%). Although information was incomplete, most patients (78%, n = 419/534) required no inpatient admission. Conclusions: EEAs furnish unique records for evaluating the impacts of Queensland's novel legislative reforms. [ABSTRACT FROM AUTHOR]

Background: Postoperative nausea and vomiting (PONV) is a common complication following surgery. Only a few risk factors have consistently been reported to be independent predictors for PONV. Aim: To report Apfel scores for orthopedic patients then correlate these scores to the number of antiemetics prescribed and subsequently administered in both the perioperative and post operative setting and determine if screening for Apfel scores is beneficial to predict PONV. Methods: A retrospective analysis of patients admitted under orthopedic units between 1st July 2020 and 31st July 2020 was conducted at a tertiary teaching hospital in Australia. Patients were screened and allocated an Apfel score and antiemetics agents prescribed and subsequently administered were recorded. Results: A total of 115 patients were screened for inclusion. Of these 4 patients met this exclusion criteria, resulting in a total sample size of 111 patients. An Apfel score of 2 was reported in 45.0% of patients, followed by 28.8% of patients scoring 3, with 12.6% scoring one. Only 5.4% of patients scored the highest risk of 4, with 8.2% of patients with no Apfel score documented. Conclusion: Orthopedic patients tend to score 2 or more in their Apfel score placing them at higher risk of postoperative nausea and/or vomiting according to the collectively validated Apfel's simplified risk score. There was no statistically significant relationship between the Apfel score and the number of antiemetic agents prescribed or administered from both the perioperative and post-operative setting following orthopedic surgery in this cohort of adult patients.

Simple Summary: Pets may die unexpectedly, without warning, and with no externally visible reason for death. As in people, postmortem examination can be performed to try to determine the cause of death. There are many diseases which may result in sudden unexpected death in domestic animals, although there is little research on companion animals and no studies performed in Australia. The aims of this study were to identify causes of sudden unexpected death in cats and dogs in Australia by examining postmortem reports and to identify risk factors for certain causes of sudden death. Sudden and unexpected death (SUD) is a common reason for animals to undergo post-mortem examination. There is limited literature examining the causes of SUD in cats and dogs, and no research specific to Australia. The purpose of this study was to investigate the epidemiology and pathology of SUD in cats and dogs in a multicentric study across Australia. Retrospective post-mortem reports of SUD in cats and dogs were obtained from four veterinary schools in Australia distributed across four states. The frequency of SUD between institutes ranged from 2.1% to 6.5%. Dogs composed the majority of the study population (76%), and males outnumbered females, particularly in the feline subpopulation. After necropsy, 37% of SUD remained cause unknown, the largest category in both cats and dogs. When cause was identified, cardiovascular disease was most common in both species, followed by gastrointestinal disease in dogs, and trauma in cats. In dogs, multinomial logistic regression identified age as a risk factor significantly associated with the four largest categories of SUD. This study identified causes of SUD in Australian cats and dogs, including novel causes not previously reported. Further, this study revealed a higher rate of unsolved SUD in Australia than can be found in the literature from other countries. [ABSTRACT FROM AUTHOR]

Transfusion-transmitted bacterial infection (TTBI) is the leading cause of transfusion-transmitted infections. Platelet components are more likely to be associated with bacterial contamination due to their storage requirements. Australian Red Cross Lifeblood introduced the bacterial contamination screening (BCS) of all platelet components in 2008. The process was recently updated with the use of BACT/ALERT® VIRTUO®, a large-volume delayed sampling (LVDS) protocol and extending platelet shelf-life to seven days. This article describes the results from the routine BCS of platelet components in Australia. Use of VIRTUO has resulted in lower false-positive rates, reducing wastage and improving platelet inventory. Our findings show that the combination of LVDS and VIRTUO improves the safety of platelet transfusions through earlier time to detection, especially for pathogenic bacterial species. Pathogenic bacteria grew within 24 h of incubation with a clear delineation between pathogenic and non-pathogenic species. The data show this protocol is very safe, with no TTBI cases during this time. There were no TTBI reports in recipients of platelet components that subsequently had a positive culture with Cutibacterium species, probably due to the low pathogenic potential of these organisms and slow replication in aerobic platelet bags. We conclude there is no advantage in incubating culture bottles beyond five days. [ABSTRACT FROM AUTHOR]

Western countries have experienced a steady increase in the number of immigrants since 2000 and these immigrants appear to be a sizeable market segment for apparel retailers in Western host countries owing to their acculturation. This study investigates how acculturation of immigrants drives their loyalty to apparel stores in Western countries. Three hundred and sixty usable responses obtained from South Asian immigrants living in Australia were analysed using PLS-SEM, non-linear variance-based SEM, and fsQCA. The results showed that immigrants' acculturation enhances their loyalty to Australian apparel stores, whereas immigrants' ethnocentrism reduces their loyalty as well as mediates the impact of ethnic community participation on their store loyalty. Ethnic community participation further weakens the association between acculturation and store loyalty. This study contributes to consumer behaviour literature and retailing in the context of immigrants' acculturation. It provides implications for retailers interested in creating a loyal customer base among immigrants in Western countries. [ABSTRACT FROM AUTHOR]

In 2013, approximately 14,000 students were enrolled at the Australian School of Business at the University of New South Wales. Although many of these students access the services and resources of the University of New South Wales's Careers and Employment (5446 students in 2012), there are still a substantial number of students who approach the end of their degree and want to transition into the Australian workforce but have little understanding about the graduate recruitment process and how to best demonstrate their employability. As a result, the present study sought to identify an effective, resource efficient and inexpensive careers intervention that would have a wide reach to enable more students to increase their confidence in applying for graduate jobs.

Australia's Privacy Act 1988 is under review with a view to bringing Australia's privacy laws into the digital era, more in line with the European Union's General Data Protection Regulation (GDPR). This article discusses how the GDPR can be refined and standardised to be more effective in protecting privacy in the digital era while not adversely affecting the digital economy that relies heavily on data. We argue that an ideal data policy should be informative and transparent about potential privacy costs while giving consumers a menu of opt‐in choices into which they can self‐select.

Accelerated soil erosion and landslides are destructive consequences of road development and intensive agriculture in the central highlands of Sri Lanka. Properly designed vegetation covers can play a vital role in erosion control. Identifying a plant that can adapt to eroded land with a low‐nutrient supply is critical for natural erosion management. A perennial creeper legume, Vigna marina, adaptable for marginal lands and used to control soil erosion in Australia, was introduced to Sri Lanka via the 2004 tsunami. The objective of this study was to assess V. marina under five different soil substrates, including a reference treatment (RT) recommended for optimal legume growth and subsoil (SS) and decomposing parent materials (DPM) without or with 20% Pinus wood biochar (SSb, DPMb). The growth parameters of V. marina were in the order RT > SSb = DPMb > SS = DPM. Following V. marina growth, nitrogen (N) content in DPM and DPMb increased from non‐detectable to 1.83 and 0.99 mg g−1, respectively. The SSb and SS recorded an increase in N by 1.38 and 0.77 mg g−1, respectively. The RT lost soil N by 3.31 mg g−1. Compared to the RT, root nodules were 3× in SSb and DPMb, 2× in SS, and >2× in DPM. Amending SS and DPM with biochar enhanced the growth of V. marina. The V. marina, in conjunction with biochar, can be an effective tool to provide vegetative cover to exposed soils and, thus, minimize soil erosion on road cuts and other land resources. Core Ideas: Vigna marina can potentially grow under extremely degraded soil conditions.Poor soil fertility favors the root nodulation and biological nitrogen fixation of V. marina.Biochar enhances legume growth, root nodulation, and biological N fixation in degraded soils.

The increasing attacks on traffic signals worldwide indicate the importance of intrusion detection. The existing traffic signal Intrusion Detection Systems (IDSs) that rely on inputs from connected vehicles and image analysis techniques can only detect intrusions created by spoofed vehicles. However, these approaches fail to detect intrusion from attacks on in-road sensors, traffic controllers, and signals. In this paper, we proposed an IDS based on detecting anomalies associated with flow rate, phase time, and vehicle speed, which is a significant extension of our previous work using additional traffic parameters and statistical tools. We theoretically modelled our system using the Dempster–Shafer decision theory, considering the instantaneous observations of traffic parameters and their relevant historical normal traffic data. We also used Shannon's entropy to determine the uncertainty associated with the observations. To validate our work, we developed a simulation model based on the traffic simulator called SUMO using many real scenarios and the data recorded by the Victorian Transportation Authority, Australia. The scenarios for abnormal traffic conditions were generated considering attacks such as jamming, Sybil, and false data injection attacks. The results show that the overall detection accuracy of our proposed system is 79.3% with fewer false alarms. [ABSTRACT FROM AUTHOR]

Pollution of a watershed by different land uses and agricultural practices is becoming a major challenging factor that results in deterioration of water quality affecting human health and ecosystems. Sustainable use of available water resources warrants reduction of Non-Point Source (NPS) pollutants from receiving water bodies through best management practices (BMPs). A hydrologic model such as the Soil and Water Assessment Tool (SWAT) can be used for analyzing the impacts of various BMPs and implementing of different management plans for water quality improvement, which will help decision makers to determine the best combination of BMPs to maximize benefits. The objective of this study is to assess the potential reductions of sediments and nutrient loads by utilizing different BMPs on the Yarra River watershed using the SWAT model. The watershed is subdivided into 51 sub-watersheds where seven different BMPs were implemented. A SWAT model was developed and calibrated against a baseline period of 1998–2008. For calibration and validation of the model simulations for both the monthly and annual nutrients and sediments were assessed by using the Nash–Sutcliffe efficiency (NSE) statistical index. The values of the NSE were found more than 0.50 which indicates satisfactory model predictions. By utilizing different BMPs, the highest pollution reduction with minimal costs can be done by 32% targeted mixed-crop area. Furthermore, the combined effect of five BMPs imparts most sediments and nutrient reductions in the watershed. Overall, the selection of a BMP or combinations of BMPs should be set based on the goals set in a BMP application project. [ABSTRACT FROM AUTHOR]

Background: The association between dietary protein intake and the risk of mortality is still controversial. The present study aimed to examine the associations between dietary total, animal and plant protein intake and all‐cause and cause‐specific mortality. Methods: Community‐dwelling men aged ≥ 70 years were recruited from local government areas surrounding Concord Hospital in Sydney, New South Wales for the Concord Health and Ageing in Men Project (CHAMP). The research dietitian administered a standardised validated diet history questionnaire to capture baseline dietary intake. In total, 794 men participated in a detailed diet history interview at the third wave. Adequacy of protein intake was assessed by comparing participant intake with the Nutrient Reference Values. Total protein intake was categorised into quintiles. Sources of protein were also captured. Mortality was ascertained through the New South Wales death registry. Cox proportional hazard models were used to assess the association between dietary total, animal and plant protein intake and risk of mortality. Results: The mean age of the CHAMP men was 81 years. In total, 162 men died during a median follow‐up of 3.7 years. Of these, 54 (33.3%) and 49 (30.2%) men died due to cancer and cardiovascular disease, respectively. There were U‐shaped associations between protein intake and all‐cause and cancer mortality. In multiple adjusted analysis, the second (hazard ratio [HR] = 0.38; 95% confidence interval [CI] = 0.18–0.82) and third (HR = 0.36; 95% CI = 0.16–0.82) quintiles of protein intakes were significantly associated with reduced risk of all‐cause and only second quintile (HR = 0.47; 95% CI = 0.10–0.93) of protein intake was significantly associated with cancer mortality. Each serve increase in animal protein was significantly associated with 12% (HR = 1.12; 95% CI = 1.00–1.26) and 23% (HR = 1.23; 95% CI = 1.02–1.49) increased risk of all‐cause mortality and cancer mortality respectively. Conversely, each serve increase in plant protein intake was significantly associated with 25% (HR = 0.75; 95% CI 0.61–0.92) and 28% (HR = 0.72; 95% CI = 0.53–0.97) reduced risk of all‐cause and cancer mortality, respectively. No such associations were observed for cardiovascular disease mortality. Conclusions: Both second and third quintiles of total protein intake were associated with reduced all‐cause and cancer mortality. Plant protein was inversely associated with all‐cause and cancer mortality, whereas animal protein intake was positively associated with mortality. Key points: Our findings suggest a U‐shaped association between life expectancy and total protein intake, in which lifespan is greatest among people with 93–113 g day–1 total protein intake, a level that might be considered moderate in Australia but high in other countries.Both second and third quintiles of total protein intake (range between 79.23 and 107.19 g day–1) were associated with reduced risk of all‐cause and cancer mortality.Higher consumption of animal‐derived proteins was associated with greater mortality risk, whereas this association was reversed when protein consumption was replaced with plant‐derived protein.

To tackle the increasing issue of heat risk in Australia and pressure of population growth, this project aimed to establish a first nationwide dynamic and interactive heat vulnerability assessment toolkit. The toolkit integrated multiple data sources, cloud computing, and Web GIS technologies to deliver cool intelligence for more heat resilient Australian cities and suburbs. A cloud-based open-source tool, iGEE, was first developed to derive land surface temperature (LST), NDBI (normalized difference built-up index) and NDVI (normalized difference vegetation index) from multiple satellite imagery on Google Earth Engine (GEE), a no-code web application allowing users to retrieve satellite data for a large area at fine scales. Following that, a python-based desktop app was then developed to calculate an integrated Heat Vulnerability Index (iHVI) for any cities and area at a fine scale of Statistical Area 1 (SA1). The iHVI toolkit allows users to construct heat sensitivity, heat adaptive capability indicators, and composite heat vulnerability index, which enables modelling of the relationships between heat, environmental and socioeconomic factors.

The Pacific Northwest Pyrocumulonimbus Event (PNE) took place in British Columbia during the evening and nighttime hours between 12 and 13 August 2017. Several pyroconvective clouds erupted on this occasion, and released in the upper troposphere and lower stratosphere unprecedented amounts of carbonaceous aerosols (300 ktn). Only a few years later, an even larger pyrocumulonimbus (pyroCb) injection took place over Australia. This event, named "the Australian New Year (ANY) event", injected up to 1100 ktn of aerosol between 29 December 2019 and 4 January 2020. Such large injections of carbonaceous aerosol modify the stratospheric radiative budgets, locally perturbing stratospheric temperatures and winds. In this study, we use the Goddard Earth Observing System Chemistry Climate Model (GEOS CCM) to study the perturbations on the stratospheric meteorology induced by an aerosol injection of the magnitude of the PNE. Our simulations include the radiative interactions of aerosols, so that their impact on temperatures and winds are explicitly simulated. We show how the presence of the carbonaceous aerosols from the pyroCb causes the formation and maintenance of a synoptic-scale stratospheric anticyclone. We follow this disturbance considering the potential vorticity anomaly and the brown carbon aerosol loading and we describe its dynamical and thermodynamical structure and its evolution in time. The analysis presented here shows that the simulated anticyclone undergoes daily expansion–compression cycles governed by the radiative heating, which are directly related to the vertical motion of the plume, and that the aerosol radiative heating is essential in maintaining the anticyclone itself.

Introduction: Post-stroke fatigue (PSF) is common and debilitating. However, while its effective management is a priority for clinicians and stroke survivors, there remains little evidence to provide guidance or underpin practice. Our aim, therefore, was to gain insights into the experiences of clinicians who routinely manage patients with fatigue. Method: Qualitative interview study. The target was to recruit a purposeful sample of approximately 20 participants with expertise in managing PSF and fatigue arising from other conditions. Maximum variation sampling was used to ensure a balance of participants across different settings. Data were analysed using a framework approach, iteratively developed and refined by including emergent themes. Results: We recruited 20 participants: nine occupational therapists (OTs), five physiotherapists, three nurses and three psychologists, which included three 'fatigue experts' from Europe and Australia. Analysis generated core themes around management and strategies used; these were similar regardless of professional background, clinical or geographical setting or condition treated. OTs felt a particular responsibility for fatigue management, although multidisciplinary teamwork was stressed by all. Conclusion: There are clear similarities in clinicians' experiences of managing PSF and fatigue across different conditions and also across professional groups. Clinicians rely predominantly on their own clinical knowledge for guidance. [ABSTRACT FROM AUTHOR]

High nitrous oxide (N2O) emissions (2–10% of fertiliser N) were observed previously from acid soils cropped with sugarcane (Saccharum officinarum) in Australia. We assessed the impact of lime, a nitrification inhibitor (NI, as 3,4-dimethylpyrazole phosphate, DMPP), and copper (Cu) on N2O emissions from an acid sugarcane soil in a laboratory experiment using (1) urea (U), (2) U + DMPP, (3) U + CuSO4.5H2O (U + Cu), and (4) U + DMPP + Cu. The treatments were applied to both an un-limed soil (pH 5.1) and a limed soil (pH 6.9) and incubated at 25 °C and 55% water holding capacity (WHC) for 28 d, and then increased to 90% WHC for another 8 d to favour denitrification. At 55% WHC, both the addition of the NI (U + DMPP) and the liming of the acid soil significantly decreased cumulative N2O emissions, due to significantly lower net nitrifications. Liming and DMPP decreased N2O emissions by 79% and 90%, respectively. However, where lime and DMPP were applied together, N2O emissions decreased by 94% compared to those in the un-limed (acid) U-treated soil. In contrast, the addition of Cu and the increase in water content to 90% WHC had no significant effect on N2O emissions. Therefore, the combined use of lime and DMPP provides the best option to decrease N2O emissions from the acid soil. [ABSTRACT FROM AUTHOR]

Identifying drought-tolerant crops/genotypes may provide a sustainable solution to improve productivity on rain-fed sodic soils. However, the identification of genotypes tolerant to sodicity has been impeded by a lack of suitable, high-throughput techniques. Here, we propose an unmanned aerial vehicle remote sensing coupled with field experimental approach to evaluate drought tolerance and/or water use of contrasting wheat genotypes by quantifying Genotype × Environment interactions on rain-fed moderately sodic and highly sodic soil sites in Australia. Significant differences (p < 0.05) between the sites and some between genotypes were observed based on remote sensing-based vegetative drought indices, while in-season agro-climatic and soil moisture conditions were similar (p > 0.10) between the sites. This suggests that genotypes at both sites would have grown with similar access to moisture if differences in soil constraints had not been present. Further, as a useful indicator of drought, a crop health index was computed by integrating drought vegetative and temperature response variables that significantly correlated with wheat yield (coefficient of determination R2 = 0.67; root mean square error RMSE = 28.4 g m−2 and R2 = 0.41; RMSE = 33.6 g m−2 for the moderately sodic and highly sodic site, respectively). Further, a drought stress tolerance index was developed using estimates of yield anomaly between the sites to differentiate genotypes tolerant to drought on sodic soils. Genotypic ranking to drought tolerance was further compared and validated with actual field measured crop water use efficiency data. Wheat genotypes Bremer and Gladius were identified as the most and least tolerant to drought on sodic soils. The research improves our understanding of genotypic response in drought stress and can assist farmers in the selection of drought-tolerant wheat genotypes in sodic soil environments. • UAV multispectral and thermal imagery were integrated for drought tolerance of wheat genotypes on sodic soils. • Drought vegetative and temperature response indices were used to quantify genotypic variations. • A new DSTI metric was developed on G×E interactions to quantify genotypic tolerance to drought. • Estimates of yield anomaly between sites using crop health index data was used to develop DSTI. • The study can be useful to improve crop productivity on rain-fed sodic soils.

Simple Summary: Squamous-cell carcinoma of the anus, being a rare cancer, requires national and international collaborations, networking, organizational proficiency and leadership to overcome barriers towards the implementation of clinical trials to establish improved standards of care treatment strategies and the conduction of translational research projects to shed light into its biology and molecular characterization. The purpose of the present study is to obtain a global frame of the scientific literature related to anal cancer, through a bibliometric analysis of the published articles during the last 20 years (2000–2020), exploring trends and common patterns in research, tracking collaboration and networks to foresee future directions in basic and clinical research. Squamous-cell carcinoma of the anus (ASCC) is a rare disease. Barriers have been encountered to conduct clinical and translational research in this setting. Despite this, ASCC has been a prime example of collaboration amongst researchers. We performed a bibliometric analysis of ASCC-related literature of the last 20 years, exploring common patterns in research, tracking collaboration and identifying gaps. The electronic Scopus database was searched using the keywords "anal cancer", to include manuscripts published in English, between 2000 and 2020. Data analysis was performed using R-Studio 0.98.1091 software. A machine-learning bibliometric method was applied. The bibliometrix R package was used. A total of 2322 scientific documents was found. The average annual growth rate in publication was around 40% during 2000–2020. The five most productive countries were United States of America (USA), United Kingdom (UK), France, Italy and Australia. The USA and UK had the greatest link strength of international collaboration (22.6% and 19.0%). Two main clusters of keywords for published research were identified: (a) prevention and screening and (b) overall management. Emerging topics included imaging, biomarkers and patient-reported outcomes. Further efforts are required to increase collaboration and funding to sustain future research in the setting of ASCC.

Asthma is the most common respiratory illness in Aboriginal and Torres Strait Islander Australians. From the Mater Mothers routinely collected perinatal data in Brisbane we have identified that 24% of Indigenous and 17% of non‐Indigenous women have pregnancies complicated by asthma. Indigenous women with asthma are more likely to have poorer birth outcomes when compared to non‐Indigenous women with asthma, with neonatal death being doubled in asthmatic Indigenous women. These data indicate that asthma management during pregnancy is an unmet need for Indigenous women and essential if we are to avoid these devastating outcomes for Indigenous families.
