- Abstract
The Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) has not previously made recommendations outlining the requirements for physics plan checks in Australia and New Zealand. A recent workforce modelling exercise, undertaken by the ACPSEM, revealed that the workload of a clinical radiation oncology medical physicist can comprise of up to 50% patient specific quality assurance activities. Therefore, in 2022 the ACPSEM Radiation Oncology Specialty Group (ROSG) set up a working group to address this issue. This position paper authored by ROSG endorses the recommendations of the American Association of Physicists in Medicine (AAPM) Task Group 218, 219 and 275 reports with some contextualisation for the Australia and New Zealand settings. A few recommendations from other sources are also endorsed to complete the position., (© 2024. Australasian College of Physical Scientists and Engineers in Medicine.)

- Abstract
This paper discusses key themes of the 15th biennial conference of the Association for Language Awareness (2020), with a focus on increasing digital engagement in language education. The COVID-19 pandemic occasioned an abrupt transition to emergency remote language teaching and learning (ERLTL) worldwide. The ALA 2020 conference was also affected by this transition; originally planned as a located conference in Geelong, Australia, it was eventually held online, a first in ALA's conference history. The current paper engages with contemporary debates of language teaching and learning in two ways. Firstly, it traces recent discussions by presenting key findings from five papers given at the conference, and secondly, via a scoping review of literature focusing on critical lessons from the pandemic regarding language teaching and learning. The review captures recent research from the Australasian region. Key debates identified in the literature include the needs of teachers and learners during the transition to online learning, and how student engagement was affected. The literatures highlight that both educators and students have been developing new practices in teaching and learning resulting from the shift to online and blended modes, which may continue to shape language education and new pedagogies in the future.

Background: Although exclusive breastfeeding is recommended for the first six months of life, research suggests that breastfeeding initiation rates and duration among Indigenous communities differ from this recommendation. Qualitative studies point to a variety of factors influencing infant feeding decisions; however, there has been no collective review of this literature published to date. Therefore, the objective of this scoping review was to identify and summarize the qualitative literature regarding Indigenous infant feeding experiences within Canada, the United States, Australia, and Aotearoa. Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses- Scoping Reviews and the Joanna Briggs Institute Guidelines, in October 2020, Medline, Embase, CINAHL, PsycINFO, and Scopus were searched for relevant papers focusing on Indigenous infant feeding experiences. Screening and full-text review was completed by two independent reviewers. A grey literature search was also conducted using country-specific Google searches and targeted website searching. The protocol is registered with the Open Science Framework and published in BMJ Open. Results: Forty-six papers from the five databases and grey literature searches were included in the final review and extraction. There were 18 papers from Canada, 11 papers in the US, 9 studies in Australia and 8 studies conducted in Aotearoa. We identified the following themes describing infant feeding experiences through qualitative analysis: colonization, culture and traditionality, social perceptions, family, professional influences, environment, cultural safety, survivance, establishing breastfeeding, autonomy, infant feeding knowledge, and milk substitutes, with family and culture having the most influence on infant feeding experiences based on frequency of themes. Conclusions: This review highlights key influencers of Indigenous caregivers' infant feeding experiences, which are often situated within complex social and environmental contexts with the role of family and culture as essential in supporting caregivers. There is a need for long-term follow-up studies that partner with communities to support sustainable policy and program changes that support infant and maternal health. [ABSTRACT FROM AUTHOR]

Although visual arts pedagogies are considered central within early childhood education programs, teacher self-efficacy has a direct impact on the quality and delivery of visual arts curricula. Until recently, the visual arts self-efficacy, pedagogical knowledge, and practice of in-service early childhood teachers have remained largely unexplored. The authors of this paper present a qualitative, iterative re-analysis of their three PhD studies which broadly focussed on early childhood visual arts praxis and specifically examined the visual arts beliefs and pedagogy of early childhood teachers in Australia and New Zealand. A thematic analysis of the intersecting self-efficacy findings raised in the three studies identifies the powerful influence of self-efficacy on teaching practice in the visual arts domain and offers new understandings about visual arts self-efficacy amongst early childhood teachers. The combined findings reveal several factors that restrain or enhance teachers' visual arts self-efficacy across time, including the impact of childhood experiences, pre-service training and epistemological beliefs. The paper also identifies several enabling conditions that appear to support teachers to develop and maintain positive visual arts self-efficacy beliefs, including practical engagement with materials, sustained professional learning, relational trust and intentional leadership. These enabling conditions offer practical strategies and research recommendations in service of positive visual arts self-efficacy to enhance quality visual arts teaching in early childhood contexts.

The introduction of statistical concepts into school curricula in Australia and New Zealand in the early 1990s initiated an ongoing research program into the learning and teaching of statistics and probability in both countries. This paper reviews the contribution of Australian and New Zealand researchers to building statistical literacy at school, alongside international developments. From recognising how students develop understanding of specific statistical and probabilistic concepts, through teacher knowledge and beliefs for teaching statistics, to intervention studies and targeted teaching, the field of statistics education has grown and changed. Statistics and probability are now well established as part of the mathematics curriculum. The importance of linking statistical literacy and statistical understanding across the curriculum, as well as in STEM, has also begun to receive attention as other subjects have recognised the importance of data in their fields. Following a comprehensive review of the field in Australia and New Zealand, this paper then considers emerging areas of interest, such as new approaches to data visualisation, and suggests future research.

Malnutrition and frailty affect up to one-third of community-dwelling older adults in Australia and New Zealand (ANZ), burdening individuals, health systems and the economy. As these conditions are often under-recognised and untreated in the community, there is an urgent need for healthcare professionals (HCPs) from all disciplines to be able to identify and manage malnutrition and frailty in this setting. This paper describes the systematic and iterative process by which a practical guide for identifying and managing malnutrition and frailty in the community, tailored to the ANZ context, was developed. The development of the guide was underpinned by the Knowledge-to-Action Framework and included the following research activities: (1) a comprehensive literature review; (2) a survey of ANZ dietitians' current practices and perceptions around malnutrition and frailty; (3) interviews with ANZ dietitians; and (4) a multidisciplinary expert panel. This resulted in the development of a guide tailored to the ANZ context that provides recommendations around how to identify and manage malnutrition and frailty in the community. It is now freely available online and can be used by all HCPs across several settings. The approach used to develop this guide might be applicable to other conditions or settings, and our description of the process might be informative to others who are developing such tools to guide practice in their healthcare environment. Malnutrition and frailty are common in Australian and New Zealand communities, burdening individuals, health systems and the economy. This paper describes the process by which an evidence-informed guide for identifying and managing these conditions in the community was developed. The guide is now freely available online and can be used by all healthcare professionals across several settings, and our description of the process might be informative to others who are developing such tools to guide practice in their healthcare environment.

Community-based primary care, such as general practice (GP) or urgent care, serves as the primary point of access to healthcare for most Australians and New Zealanders. Coronavirus disease 2019 (COVID-19) has created significant and ongoing disruptions to primary care. Traditional research methods have contributed to gaps in understanding the experiences of primary care workers during the pandemic. This paper describes a novel research design and method that intended to capture the evolving impact of the COVID-19 pandemic on primary care workers in Australia and New Zealand. Recurrent, rapid cycle surveys were fielded from May 2020 through December 2021 in Australia, and May 2020 through February 2021 in New Zealand. Rapid survey development, fielding, triangulated analysis and dissemination of results allowed close to real-time communication of relevant issues among general practice workers, researchers and policy-makers. A conceptual model is presented to support longitudinal analysis of primary care worker experiences during the COVID-19 pandemic in Australia and New Zealand, and key learnings from applying this novel method are discussed. This paper will assist future research teams in development and execution of policy-relevant research in times of change and may inform further areas of interest for COVID-19 research in primary care.

This paper reviews tourism-relevant advances in climate science and tourism policy in the Australasia region over the past 20 years, focusing particularly on the seven years (2015–2021) since the IPCC Fifth Assessment Report. Within the Australasia region, Australia and New Zealand have a complicated relationship with climate change, as both countries are dependent upon stable climates for tourism while contributing to high tourism greenhouse gas emissions. Both are economically reliant on their respective tourism industries, which market environmental products to predominantly long-haul tourism markets. In this paper we critically address the climate change context in Australasia, reviewing the tourism systems, climate risks and carbon risks in the region. We critique the (dis)connection of climate change and tourism policy at the national scale in the region, and find that the extent of climate responses in relation to tourism are generally limited to descriptive (Generation 1) and normative (Generation 2) approaches. We conclude that serious deficiencies remain in the climate science – tourism policy translation required to transform the tourism systems of Australia and New Zealand in response to climate change.

Introduction: It is now widely recognised that engaging consumers in research activities can enhance the quality, equity and relevance of the research. Much of the commentary about consumer engagement in research focuses on research processes and implementation, rather than dissemination in conference settings. This article offers reflections and learnings from consumers, researchers and conference organisers on the 12th Health Services Research Conference, a biennial conference hosted by the Health Services Research Association of Australia and New Zealand (HSRAANZ). Method: We were awarded funds via a competitive application process by Bellberry Limited, a national not‐for‐profit agency with a focus on improving research quality, to incorporate consumer engagement strategies in conference processes and evaluate their impact. Findings: Strategies included consumer scholarships, a buddy system, designated quiet space and consumer session co‐chairs; the reflections explored in this paper were collected in the funded, independent evaluation. Our insights suggest a need for more structured consumer involvement in conference planning and design, as well as the development of specific engagement strategies. Conclusion: To move toward active partnership in scientific conference settings, our experience reinforces the need to engage consumers as members in designing and conducting research and in presenting research and planning conference content and processes. Public Contribution: Consumer engagement in research dissemination at conferences is the focus of this viewpoint article. Consumers were involved in the conception of this article and have contributed to authorship at all stages of revisions and edits. [ABSTRACT FROM AUTHOR]

Simple Summary: Many cancer treatments, including chemotherapy, targeted therapy, immunotherapy, and radiotherapy, can cause skin side effects. These are called 'dermatologic toxicities' or 'skin toxicities'. There are many different types of skin toxicities, some of which can not only affect the quality of life but also lead to cancer treatment being stopped or slowed down. This paper gives an overview of 12 of the most common skin toxicities experienced by people receiving cancer treatment. These include rashes, dry skin, skin irritation, hair loss, changes in skin colouring, and itching. We have provided Australia/New Zealand-specific recommendations on how skin toxicities can be prevented and managed, including the role of dermocosmetic solutions. Cancer systemic therapeutics and radiotherapy are often associated with dermatological toxicities that may reduce patients' quality of life and impact their course of cancer treatment. These toxicities cover a wide range of conditions that can be complex to manage with increasing severity. This review provides details on twelve common dermatological toxicities encountered during cancer treatment and offers measures for their prevention and management, particularly in the Australian/New Zealand context where skincare requirements may differ to other regions due to higher cumulative sun damage caused by high ambient ultraviolet (UV) light exposure. Given the frequency of these dermatological toxicities, a proactive phase is envisaged where patients can actively try to prevent skin toxicities. [ABSTRACT FROM AUTHOR]

To the detriment of liberal democracy, governments have struggled to prevent the exploitation of personal data for voter manipulation in the digital era. Laws pertaining to political microtargeting are often piecemeal and tend to derive from a combination of laws on electoral advertising and privacy. Evidence indicates that this approach is insufficient to curtail microtargeting. However, little is known about the regulation of microtargeting outside of the European and US contexts within which the bulk of anti‐microtargeting research has been undertaken. Accordingly, this paper aims to shed light on the preparedness of the law in Australia and New Zealand to mitigate the potential harms of political microtargeting. A comparative analysis of legislation pertaining to microtargeting is therefore undertaken using a blended approach of comparative law and content analysis. This paper: (1) identifies current legislation relevant to microtargeting in Australia and New Zealand; (2) assesses patterns of similarity and difference between each country's laws in relation to microtargeting; and (3) evaluates the preparedness of current legislation to curtail microtargeting in an evolving social media landscape. It finds that in both countries, legislation is sufficiently robust to mitigate microtargeting in some limited circumstances, but a cohesive regulatory approach is needed to constrain the most insidious microtargeting operations.

This paper develops subgame consistent cooperative equilibria of multi-objective dynamic games. The presence of multiple objectives in decision-making is prevalent and inherent. Given that the set of objectives of each player will be affected by the actions of other players, non-coordinated maximization by individual players could lead to the case where some prominent objectives may reach an undesirably level. Cooperation is the best way to alleviate the problem and enhance the participants' payoffs. This paper presents the techniques for solving subgame consistent cooperative equilibria of multi-objective dynamic games with utility-based players. In such an equilibrium, individual rationality, group efficiency, and subgame consistency are realized. An application of collaboration between Australia and New Zealand is provided. This is the first time that subgame consistent cooperative equilibria are applied in multi-objective dynamic games with utility-based players, ample applications in various fields are expected.

An increasingly complex and demanding research landscape has seen university libraries rapidly evolve their services. While research data management, bibliometrics, and research impact services have predominantly featured in the literature to date, the full scope of support libraries are currently providing to their institutions is unknown. This paper aims to present an up-to-date view of the scope and extent of research support services by university libraries across Australia and Aotearoa New Zealand. A coding process analyzed content data from university library websites. Eleven research support areas were identified. Service delivery is split between synchronous and asynchronous modes. This paper describes a lived experience of an evidence-based library and information practice approach to improving research support services at two Australian university libraries, and while it highlights continued maturation of research support services, more research is needed to better understand influences on service development.

Over the past two decades, there have been important changes to interprofessional education in Australia and New Zealand. Interprofessional education has slowly shifted from peripheral, small-scale education activities attended by volunteer students to become an expectation of many health professional courses to meet accreditation requirements and community expectations of a collaborative healthcare system. In Australia, interprofessional education curricula have been facilitated by increased accreditation expectations and a series of national large-scale funded projects. However, despite declarations of intent and direction, strategic implementation of nationwide recommendations has not been achieved. In New Zealand, large-scale funding has not been available to facilitate the implementation of interprofessional education in the professional courses. Instead, interprofessional education initiatives have been driven by a small group of champions. Furthermore, efforts to achieve the World Health Organization's (2010) vision of interprofessional education across the education spectrum--to ensure the future and current health workforce have the competencies for interprofessional collaboration--have been hampered in our region by the focus on interprofessional education within tertiary education. This paper outlines the transnational status of interprofessional education and the role of the Australian and New Zealand Association for Health Professional Educators (ANZAHPE) and the Australasian Interprofessional Practice and Education Network (AIPPEN) in progress to date. We conclude with several suggestions for future interprofessional education across our two countries. [ABSTRACT FROM AUTHOR]

Cultural safety is increasingly recognised as imperative to delivering accessible and acceptable healthcare for First Nations Peoples within Australia and in similar colonised countries. A literature review undertaken to inform the inaugural Caring for Australians with Renal Insufficiency (CARI) guidelines for clinically and culturally safe kidney care for Aboriginal and Torres Strait Islander peoples revealed a timeline of the emergence of culturally safe kidney care in Australia. Thirty years ago, kidney care literature was purely biomedically focused, with culture, family and community viewed as potential barriers to patient 'compliance' with treatment. The importance of culturally informed care was increasingly recognised in the mid‐1990s, with cultural safety within kidney care specifically cited from 2014 onwards. The emergence timeline is discussed in this paper in relation to the five principles of cultural safety developed by Māori nurse Irihapeti Ramsden in Aotearoa/New Zealand. These principles are critical reflection, communication, minimising power differences, decolonisation and ensuring one does not demean or disempower. For the kidney care workforce, culturally safe care requires ongoing critical reflection, deep active listening skills, decolonising approaches and the eradication of institutional racism. Cultural safety is the key to truly working in partnership, increasing Indigenous Governance, respectful collaboration and redesigning kidney care. [ABSTRACT FROM AUTHOR]

Using freedom of information requests, we examine the operation of the Patents Māori Advisory Committee of Aotearoa New Zealand. The Committee advises the Intellectual Property Office of New Zealand on whether inventions claimed in a patent application are derived from Māori traditional knowledge or from indigenous plants or animals; and if so, whether the commercial exploitation of that invention is likely to be contrary to Māori values. There is limited publicly available information on the operations of the Committee and the decision‐making process undertaken in reviewing applications. The requests and our searches identified 13 patents referred to the Committee, of which most (9 of 13) dealt with inventions related to Mānuka (Leptospermum scoparium), a taonga species known for its role in producing unique honey. Only two applications have been found to be contrary to Māori values, and these applications have both since been abandoned. The review of applications found to be 'not contrary to Māori values' is instructive, identifying important considerations taken into account by the Committee in reaching a decision, including the importance of benefit sharing and engagement with Māori in considering whether an invention may be contrary to Māori values. The analysis highlights the limitations of the Committee in reviewing only those applications filed in Aotearoa New Zealand and referred to the Committee for advice and identifies the importance of mechanisms such as disclosure of origin to ensure all relevant applications are reviewed by the Committee. The paper concludes by highlighting how the operation of the Committee may inform the development of similar bodies in other jurisdictions, such as Australia. [ABSTRACT FROM AUTHOR]

Artificial Intelligence (AI) carries the potential for unprecedented disruption in radiology, with possible positive and negative consequences. The integration of AI in radiology holds the potential to revolutionize healthcare practices by advancing diagnosis, quantification, and management of multiple medical conditions. Nevertheless, the ever‑growing availability of AI tools in radiology highlights an increasing need to critically evaluate claims for its utility and to differentiate safe product offerings from potentially harmful, or fundamentally unhelpful ones. This multi‑society paper, presenting the views of Radiology Societies in the USA, Canada, Europe, Australia, and New Zealand, defines the potential practical problems and ethical issues surrounding the incorporation of AI into radiological practice. In addition to delineating the main points of concern that developers, regulators, and purchasers of AI tools should consider prior to their introduction into clinical practice, this statement also suggests methods to monitor their stability and safety in clinical use, and their suitability for possible autonomous function. This statement is intended to serve as a useful summary of the practical issues which should be considered by all parties involved in the development of radiology AI resources, and their implementation as clinical tools.

Using historical data on energy from (Malanima 2020) and GDP from the Maddison Project Database, this paper investigates the energy-growth nexus in a less-studied region, mainly Australia and New Zealand, since 1870. The long annual series allow meaningful application of recently developed time-varying and quantile Granger causality analysis. Results indicate that there is a bi-directional Granger causal relationship between economic growth and energy, coal, and oil consumption at both ends of the distribution, and during various time periods over the past 150 years. Little evidence is found on the Granger causal relationship from gas consumption to economic growth, but some evidence on the direction from economic growth to gas consumption. The Granger causal relationships between electricity consumption and GDP change over time, but results suggest much closer links between the two in most recent decades, and big (positive and negative) changes in electricity consumption significantly Granger causes economic growth.

The centralisation of trauma services in western countries has led to an improvement in patient outcomes. Effective trauma systems include a pre‐hospital trauma system. Delivery of high‐level pre‐hospital trauma care must include identification of potential major trauma patients, access and correct application of lifesaving interventions (LSIs) and timely transport to definitive care. Globally, many nations endorse nationwide pre‐hospital major trauma triage guidelines, to ensure a universal approach to patient care. This paper examined clinical guidelines from all 10 EMS in Australia and Aotearoa/New Zealand. All relevant trauma guidelines were included, and key information was extracted. Authors compared major trauma triage criteria, all LSI included in guidelines, and guidelines for transport to definitive care. The identification of major trauma patients varied between all 10 EMS, with no universal criteria. The most common approach to trauma triage included a three‐step assessment process: physiological criteria, identified injuries and mechanism of injury. Disparity between physiological criteria, injuries and mechanism was found when comparing guidelines. All 10 EMS had fundamental LSI included in their trauma guidelines. Fundamental LSI included haemorrhage control (arterial tourniquets, pelvic binders), non‐invasive airway management (face mask ventilation, supraglottic airway devices) and pleural wall needle decompression. Variation in more advanced LSI was evident between EMS. Optimising trauma triage guidelines is an important aspect of a robust and evidence driven trauma system. The lack of consensus in trauma triage identified in the present study makes benchmarking and comparison of trauma systems difficult. Effective trauma systems include a pre‐hospital trauma system. Delivery of high‐level pre‐hospital trauma care must include identification of potential major trauma patients, access and correct application of lifesaving interventions (LSIs), and timely transport to definitive care. Authors compared major trauma triage criteria, all LSI included in guidelines, and guidelines for transport to definitive care, and identified variations between all systems included in the present study.

PARENTING ,HIGHER education ,RIGHT to education ,EDUCATIONAL equalization - Abstract
A range of structural, interpersonal and individual factors contribute to the extent to which people can access higher education and experience inclusion and equity once there. This paper considers the experiences of parents in higher education settings, and examines the extent to which universities in two countries support parents' inclusion through the facilities and services evident on their campus maps. The inclusion of such parent-related facilities and services on campus maps reflects not only a commitment to providing support infrastructure, but importantly to making them visible, promoting a culture of normalisation of parents and parenting in higher education. We used manifest content analysis to examine the campus maps of Australia's n = 37 and New Zealand's n = 8 public universities, with a total of 281 distinct physical sites identified. Childcare services, parents' rooms, baby change tables, nursing areas and parking-related services were identified, although the prevalence within and across sites varied greatly. A lack of clarity in labelling and inconsistency across different modes of maps pose barriers to access and visibility in some cases, and overall, reporting of parenting-related infrastructure was limited. Our analysis indicates that parents attending university campuses may face ongoing challenges as they navigate their dual academic and parenting responsibilities. [ABSTRACT FROM AUTHOR]

Rosemary Callingham and Jane Watson
- Abstract
The introduction of statistical concepts into school curricula in Australia and New Zealand in the early 1990s initiated an ongoing research program into the learning and teaching of statistics and probability in both countries. This paper reviews the contribution of Australian and New Zealand researchers to building statistical literacy at school, alongside international developments. From recognising how students develop understanding of specific statistical and probabilistic concepts, through teacher knowledge and beliefs for teaching statistics, to intervention studies and targeted teaching, the field of statistics education has grown and changed. Statistics and probability are now well established as part of the mathematics curriculum. The importance of linking statistical literacy and statistical understanding across the curriculum, as well as in STEM, has also begun to receive attention as other subjects have recognised the importance of data in their fields. Following a comprehensive review of the field in Australia and New Zealand, this paper then considers emerging areas of interest, such as new approaches to data visualisation, and suggests future research.

Alisa Howlett, Eleanor Colla, and Rebecca Joyce
- Abstract
An increasingly complex and demanding research landscape has seen university libraries rapidly evolve their services. While research data management, bibliometrics, and research impact services have predominantly featured in the literature to date, the full scope of support libraries are currently providing to their institutions is unknown. This paper aims to present an up-to-date view of the scope and extent of research support services by university libraries across Australia and Aotearoa New Zealand. A coding process analyzed content data from university library websites. Eleven research support areas were identified. Service delivery is split between synchronous and asynchronous modes. This paper describes a lived experience of an evidence-based library and information practice approach to improving research support services at two Australian university libraries, and while it highlights continued maturation of research support services, more research is needed to better understand influences on service development.

26. Microteaching Networks in Higher Education
- Author

Sonia Santoveña-Casal, Javier Gil-Quintana, and José Javier Hueso-Romero
- Abstract
Purpose: Microteaching is a teacher training method based on microclasses (groups of four or five students) and microlessons lasting no more than 5-20 min. Since it was first explored in the late 20th century in experiments at Stanford University, microteaching has evolved at the interdisciplinary level. The purpose of this paper is to examine the networks found via an analytical bibliometric study of the scientific output related with microteaching in teacher training, through a study and examination of the Web of Science database. Design/methodology/approach: This research was conducted with the VOSviewer tool for content analysis through data mining and scientific network structure mapping by means of the normalisation technique. This technique is based on the association strength indicator, which is interpreted as a measurement of the similarity of the units of analysis. Findings: Two hundred and nine articles were thus obtained from the Web of Science database. The networks generated and the connections among the various items, co-authorship and co-citation are presented in the results, which clearly indicates that there are significant authors and institutions in the field of microteaching. The largest cluster is made up of institutions such as Australian Catholic University. The most often-cited document is by Rich and Hannafin. Allen (1968), who defines microteaching as a technique based on microclasses and microlessons, is the author most often cited and has the largest number of connections. Research limitations/implications: This research's limitations concern either aspects that lie beyond the study's possibilities or goals that have proved unattainable. The second perspective, which focuses on skill transfer, contains a lower percentage of documents and therefore has a weaker central documentary structure. Lastly, the authors have also had to bear in mind the fact that the scientific output hinges upon a highly specific realm, the appearance and/or liberalisation of digital technologies and access to those technologies in the late 20th century. Originality/value: This research shows that microteaching is a promising area of research that opens up vast possibilities in higher education teacher training for application in the realm of technologies. This paper could lead to several lines of future research, such as access to and the universal design of learning from the standpoint of different communication and pedagogical models based on microteaching.

27. Issues in Cross-National Comparisons of Institutions That Provide Vocational Education and Training

Michael L. Skolnik
- Abstract
Colleges are important providers of vocational education and training and in some countries they are the major provider. Although the international literature on colleges has grown considerably in the past two decades, it still consists primarily of qualitative descriptions of college sectors in different countries. Quantitative studies of differences in the activity mix of colleges in different countries could improve knowledge of international variation in the roles of colleges and provide a stronger foundation for study of the sources and consequences of variation in college roles. After reviewing different methodological frameworks for comparative analysis of college activity, the research reported here employs one of these frameworks to analyse differences in the activity mix of colleges in five countries. In addition to finding some noteworthy differences among the five countries, the paper also identified several problems of comparability of college data from different countries. The paper concludes that the development of internationally comparable data on colleges would require leadership by international organisations and agencies and is an undertaking well worth pursuing both for the benefits that it could bring to those whom colleges serve and for its contribution to the advancement of comparative study of vocational education and training.

Anh Ngoc Quynh Phan
- Abstract
This paper focuses on Vietnamese PhD students' imaginative geographies of their destination countries. Using the data collected from in-depth semi-structured interviews with 18 Vietnamese PhD students, the study examines the participants' preparation for their sojourn before their departure, as well as their first multi-sensory experiences of the study countries on the first days of arrival, which then revealed how their imaginative geographies had been constructed and how they perceived the contrast between their imaginative geographies and reality. The findings of the study suggest that when the students chose to study overseas, they had diverse imaginations of the destinations that had been constructed over long periods of time thanks to the influences of movies, newspapers, media, and experiences of those in their social networks. Furthermore, the paper also highlights the collective imagination about countries in the West and the imagination of the collective West among Vietnamese students.

- Abstract
This paper documents historical and contemporary evidence of the HPE field's honouring Indigenous ways of knowing, being and doing -- and argues that much more needs to be done. Underpinning this is our philosophical belief that honouring Indigenous knowledges ultimately contributes to planetary health. We begin the paper with the positioning of ourselves within the context of this work. Extrapolating this, we introduce our particular contexts, to help convey the complexity of socio-historical and political influences. Following this, we document a series of events in our field of HPE that convey working towards honouring Indigenous knowledges and illustrate examples of Indigenous ways in educational institutions. The final section introduces the other papers of this special issue. The issue captures a moment in time where practices associated with racism, specifically towards First Peoples, at systemic, institutional, embodied and epistemic levels, are being challenged and countered, yet still require further dismantling. We regard the movement towards obligations of not just acknowledging, but also engaging with and for First Peoples, as still not strong enough to claim our field is inclusive or honouring. Such movements signal important opportunities not just for HPE curricula, but also for the pedagogies, topics, partnerships and research for planetary health more widely.

This perspective paper provides industry leaders, researchers and policy developers strategic approaches to ensure that the welfare of dairy cattle is protected at the same time as the industry increases its resilience to climate change. Farm systems and practices will evolve in response to the direct impacts of climate change and/or from responses to climate change, such as mitigation strategies to reduce dairy's greenhouse-gas (GHG) emissions. The five domains framework (nutrition, physical environment, health, behaviour, mental state) was used to assess the potential impacts on animal welfare and strategies to minimise these impacts are outlined. Given that the future climate cannot be certain these approaches can be applied under a range of emissions pathways to (1) ensure that the effects of GHG mitigations on animal welfare are considered during their development, (2) engage with end users and the public to ensure solutions to the effects of climate change and weather variability are accepted by consumers and communities, (3) identify and measure the areas where improved animal health can contribute to reducing GHG emissions from dairy production, (4) ensure those supporting farmers to develop and manage their farm systems understand what constitutes a good quality of life for dairy cattle, (5) ensure effective surveillance of animal disease and monitoring of welfare outcomes and farm-system performance in response to climate change and GHG mitigations. Overall, these strategies require a multidisciplinary co-development approach to ensure that the welfare of dairy cattle is protected at the same time as the industry increases its resilience to the wider impacts of a changing climate.

31. A Review of Work-Integrated Learning for PhD Students
- Author

Kristin Bracewell, Irene Sheridan, and Stephen Cassidy
- Abstract
Work-integrated learning (WIL) has been suggested as a potentially beneficial addition to modern doctoral education. However, there is little research outlining the specificities of WIL aimed at PhD students. This paper explores the range of WIL opportunities available to PhD students through a review of secondary data. The findings indicate that WIL opportunities are non-homogenous and vary widely across their structure and implementation. Patterns emerge to indicate that WIL opportunities tend to be optional, paid, short-term, focused on horizontal learning development, and provide opportunities for boundary crossing outside of academia. These findings imply that WIL has the potential to complement doctoral education by providing opportunities to experience cross-sector or cross-discipline learning and development. However, higher education institutes might consider becoming more involved in the design and implementation of WIL for PhD students. Additional research is required to understand how WIL opportunities fit into doctoral education and to evaluate existing WIL opportunities.

Midlife, beginning at 40 years and extending to 65 years, a range that encompasses the late reproductive to late menopausal stages, is a unique time in women's lives, when hormonal and physical changes are often accompanied by psychological and social evolution. Access to sexual health and sexual well-being (SHSW) services, which include the prevention and management of sexually transmitted infections, contraception and the support of sexual function, pleasure and safety, is important for the health of midlife women, their relationships and community cohesion. The objective was to use the socio-ecological model to synthesise the barriers and enablers to SHSW services for midlife women in high-income countries. A systematic review of the enablers and barriers to women (including trans-gender and non-binary people) aged 40–65 years accessing SHSW services in high-income countries was undertaken. Four databases (PubMed, PsycINFO, Web of Science and Google Scholar) were searched for peer-reviewed publications. Findings were thematically extracted and reported in a narrative synthesis. Eighty-one studies were included; a minority specifically set out to study SHSW care for midlife women. The key barriers that emerged were the intersecting disadvantage of under-served groups, poor knowledge, about SHSW, and SHSW services, among women and their healthcare professionals (HCPs), and the over-arching effect of stigma, social connections and psychological factors on access to care. Enablers included intergenerational learning, interdisciplinary and one-stop women-only services, integration of SHSW into other services, peer support programmes, representation of minoritised midlife women working in SHSW, local and free facilities and financial incentives to access services for under-served groups. Efforts are needed to enhance education about SHSW and related services among midlife women and their healthcare providers. This increased education should be leveraged to improve research, public health messaging, interventions, policy development and access to comprehensive services, especially for midlife women from underserved groups. Plain language summary: Sexual health and sexual wellbeing services for midlife women in high income countries Midlife, beginning at 40 years and extending to 65 years, a range that encompasses the late reproductive to late menopausal stages, is a unique time in women's lives. Access to Sexual Health and Sexual Wellbeing (SHSW) services, which include the prevention and management of sexually transmitted infections, contraception and the support of sexual function, pleasure and safety, is important for the health of midlife women, their relationships and community cohesion. The objective of this systematic review was to use the socio-ecological model to synthesise the barriers and enablers to SHSW services for midlife women in high income countries.

Background: Aboriginal and Torres Strait Islander peoples are disproportionately impacted by type 2 diabetes. Continuous glucose monitoring (CGM) technology (such as Abbott Freestyle Libre 2, previously referred to as Flash Glucose Monitoring) offers real-time glucose monitoring that is convenient and easy to use compared to self-monitoring of blood glucose (SMBG). However, this technology's use is neither widespread nor subsidised for Aboriginal and Torres Strait Islander peoples with type 2 diabetes. Building on existing collaborations with a national network of Aboriginal and Torres Strait Islander communities, this randomised controlled trial aims to assess the effect of CGM compared to SMBG on (i) haemoglobin A1c (HbA1c), (ii) achieving blood glucose targets, (iii) reducing hypoglycaemic episodes and (iv) cost-effective healthcare in an Aboriginal and Torres Strait Islander people health setting. Methods: This is a non-masked, parallel-group, two-arm, individually randomised, controlled trial (ACTRN12621000753853). Aboriginal and Torres Strait Islander adults with type 2 diabetes on injectable therapy and HbA1c ≥ 7.5% (n = 350) will be randomised (1:1) to CGM or SMBG for 6 months. The primary outcome is change in HbA1c level from baseline to 6 months. Secondary outcomes include (i) CGM-derived metrics, (ii) frequency of hypoglycaemic episodes, (iii) health-related quality of life and (iv) incremental cost per quality-adjusted life year gained associated with the CGM compared to SMBG. Clinical trial sites include Aboriginal Community Controlled Organisations, Aboriginal Medical Services, primary care centres and tertiary hospitals across urban, rural, regional and remote Australia. Discussion: The trial will assess the effect of CGM compared to SMBG on HbA1c for Aboriginal and Torres Strait Islander people with type 2 diabetes in Australia. This trial could have long-term benefits in improving diabetes management and providing evidence for funding of CGM in this population.

Introduction: The Revised Cardiac Risk Index (RCRI) is a six-parameter model that is commonly used in assessing individual 30-day perioperative cardiovascular risk before general surgery, but its use in patients on chronic kidney replacement therapy (KRT) is unvalidated. This study aimed to externally validate RCRI in this patient group over a 15-year period. Methods: Data linkage was used between the the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry and jurisdictional hospital admisisons data across Australia and New Zealand to identify all incident and prevalent patients on chronic KRT between 2000 and 2015 who underwent elective abdominal surgery. Chronic KRT was categorised as haemodialysis (HD), peritoneal dialysis (PD), home haemodialysis (HHD) and kidney transplant. The outcome of interest was major adverse cardiovascular event (MACE) which was defined as nonfatal myocardial infarction, nonfatal stroke, non-fatal cardiac arrest and cardiovascular mortality at 30 days. Logistic regression was used with the RCRI score included as a continuous variable to estimate discrimination by area under the receiver operating curve (AUROC). Calibration was evaluated using a calibration plot. Clinical utility was assessed using a decision curve analysis to determine the net benefit. Results: A total of 5094 elective surgeries were undertaken, and MACE occurred in 153 individuals (3.0%). Overall, RCRI had poor discrimination in patients on chronic KRT undergoing elective surgery (AUROC 0.67), particularly in patients aged greater than 65 years (AUROC 0.591). A calibration plot showed that RCRI overestimated risk of MACE. The expected-to-observed outcome ratio was 6.0, 5.1 and 2.5 for those with RCRI scores of 1, 2 and ≥ 3, respectively. Discrimination was moderate in patients under 65 years and in kidney transplant recipients, with AUROC values of 0.740 and 0.718, respectively. Overestimation was common but less so for kidney transplant recipients. Decision curve analysis showed that there was no net benefit of using the tool in neither the overall cohort nor patients under 65 years, but a slight benefit associated with threshold probability > 5.5% in kidney transplant recipients. Conclusions: The RCRI tool performed poorly and overestimated risk in patients on chronic dialysis, potentially misinforming patients and clinicians about the risk of elective surgery. Further research is needed to define a more comprehensive means of estimating risk in this unique population. [ABSTRACT FROM AUTHOR]

Background: There is a need to increase the capacity and capability of musculoskeletal researchers to design, conduct, and report high-quality clinical trials. The objective of this study was to identify and prioritise clinical trial learning needs of musculoskeletal researchers in Australia and Aotearoa New Zealand. Findings will be used to inform development of an e-learning musculoskeletal clinical trials course. Methods: A two-round online modified Delphi study was conducted with an inter-disciplinary panel of musculoskeletal researchers from Australia and Aotearoa New Zealand, representing various career stages and roles, including clinician researchers and consumers with lived experience of musculoskeletal conditions. Round 1 involved panellists nominating 3–10 topics about musculoskeletal trial design and conduct that they believe would be important to include in an e-learning course about musculoskeletal clinical trials. Topics were synthesised and refined. Round 2 asked panellists to rate the importance of all topics (very important, important, not important), as well as select and rank their top 10 most important topics. A rank score was calculated whereby higher scores reflect higher rankings by panellists. Results: Round 1 was completed by 121 panellists and generated 555 individual topics describing their musculoskeletal trial learning needs. These statements were grouped into 37 unique topics for Round 2, which was completed by 104 panellists. The topics ranked as most important were: (1) defining a meaningful research question (rank score 560, 74% of panellists rated topic as very important); (2) choosing the most appropriate trial design (rank score 410, 73% rated as very important); (3) involving consumers in trial design through to dissemination (rank score 302, 62% rated as very important); (4) bias in musculoskeletal trials and how to minimise it (rank score 299, 70% rated as very important); and (5) choosing the most appropriate control/comparator group (rank score 265, 65% rated as very important). Conclusions: This modified Delphi study generated a ranked list of clinical trial learning needs of musculoskeletal researchers. Findings can inform training courses and professional development to improve researcher capabilities and enhance the quality and conduct of musculoskeletal clinical trials. [ABSTRACT FROM AUTHOR]

37. A Systematic Narrative Synthesis Review of the Effectiveness of Genre Theory and Systemic Functional Linguistics for Improving Reading and Writing Outcomes within K-10 Education

Clarence Green, Iain Giblin, and Jean Mulder
- Abstract
This paper reports a systematic narrative synthesis review conducted on the educational effectiveness of genre theory/systemic functional linguistics pedagogies for improving reading and writing outcomes in K-10 education within mainstream classrooms in Australia, the UK, the USA, New Zealand, and Canada. This framework has significant influence on reading and writing curriculum, teacher training, and literacy practices. However, its evidence base has never been systematically reviewed. An exhaustive database search sourced 7846 potentially relevant studies, which were screened according to guidelines for evaluating evidence through systematic narrative synthesis reviews and standardly applied criteria for educational evidence (e.g., The Centre for Education Statistics and Evaluation, What Works Clearinghouse). Very few peer-reviewed intervention studies with control groups and quantitatively measured outcomes were found. A surprising result. Those studies showing positive effects had flaws in research design and quality that preclude their use as educational evidence. This systematic review indicates that there is insufficient rigorous evidence of the benefits, or lack thereof, of genre theory/systemic functional linguistics--based approaches to teaching reading and writing within K-10 education, at least in terms of measurable outcomes for students. More high-quality research needs to be undertaken as the current research record is not sufficient to prove or disprove the value of this approach.

• The compressive behaviour of square RACFSST stub columns after exposure to fire is investigated. • Twelve post-fire compression tests are conducted. • The influences of heating durations and RCA replacement ratios are discussed. • Thermal and mechanical FE models are validated against test results and then used to conduct parametric studies. • The relevant design codes are assessed against the test and FE data. Experimental and numerical studies on the cross-section compressive behaviour and residual resistances of square recycled aggregate concrete-filled stainless steel tube (RACFSST) stub columns after exposure to fire are reported in this paper. An experimental programme was firstly carried out on twelve stub column specimens with three recycled coarse aggregate replacement ratios (0%, 35% and 70%) after exposure to the ISO-834 standard fire for 0 min (i.e. at ambient temperature), 15 min, 30 min and 45 min. The test results, including load–end shortening curves, failure loads and failure modes, were presented, with the initial compressive stiffness and confinement effect analysed. The experimental programme was followed by a numerical modelling programme, where thermal and mechanical finite element models were developed and validated against the test results and afterwards used to conduct parametric studies to generate additional numerical data over a wide range of cross-section dimensions. Based on the test and numerical data, the relevant design rules for square natural aggregate concrete-filled carbon steel tube stub columns at ambient temperature, as specified in the European code, Australia/New Zealand standard and American specification, were evaluated, using post-fire material properties, for their applicability to square RACFSST stub columns after exposure to fire. The evaluation results generally revealed that the European code and Australian/New Zealand standard led to a good level of design accuracy, while the American specification resulted in slightly conservative post-fire cross-section compression resistance predictions.

Background: There are no approved pharmacotherapies for methamphetamine use disorder. Two preliminary phase 2 randomised controlled trials have found mirtazapine, a tetracyclic antidepressant, to be effective in reducing methamphetamine use. The proposed Tina Trial is the first phase 3 placebo-controlled randomised trial to examine the effectiveness and safety of mirtazapine as an outpatient pharmacotherapy for methamphetamine use disorder. Methods: This is a multi-site phase 3 randomised, double-blind, placebo-controlled parallel trial. Participants are randomly allocated (1:1) to receive either mirtazapine (30 mg/day for 12 weeks) or matched placebo, delivered as a take-home medication. The target population is 340 people aged 18–65 years who have moderate to severe methamphetamine use disorder. The trial is being conducted through outpatient alcohol and other drug treatment clinics in Australia. The primary outcome is measured as self-reported days of methamphetamine use in the past 4 weeks at week 12. Secondary outcomes are methamphetamine-negative oral fluid samples, depressive symptoms, sleep quality, HIV risk behaviour and quality of life. Other outcomes include safety (adverse events), tolerability, and health service use. Medication adherence is being monitored using MEMS® Smart Caps fitted to medication bottles. Discussion: This trial will provide information on the safety and effectiveness of mirtazapine as a pharmacotherapy for methamphetamine use disorder when delivered as an outpatient medication in routine clinical practice. If found to be safe and effective, this trial will support an application for methamphetamine use disorder to be included as a therapeutic indication for the prescription of mirtazapine.

In April 2020, the Aboriginal and Torres Strait Islander COVID-19 Point-of-Care (POC) Testing Program was initiated to improve access to rapid molecular-based SARS-CoV-2 detection in First Nations communities. At capacity, the program reached 105 health services across Australia. An external review estimated the program contributed to averting between 23,000 and 122,000 COVID-19 infections within 40 days of the first infection in a remote community, equating to cost savings of between AU$337 million and AU$1.8 billion. Essential to the quality management of this program, a customised External Quality Assessment (EQA) program was developed with the Royal College of Pathologists of Australasia Quality Assurance Programs (RCPAQAP). From July 2020 to May 2022, SARS-CoV-2 EQA participation ranged from 93 to 100%. Overall concordance of valid EQA results was high (98%), with improved performance following the first survey. These results are consistent with those reported by 12 Australian and 4 New Zealand laboratories for three SARS-CoV-2 RNA EQA surveys in March 2020, demonstrating that SARS-CoV-2 RNA POC testing in primary care settings can be performed to an equivalent laboratory analytical standard. More broadly, this study highlights the value of quality management practices in real-world testing environments and the benefits of ongoing EQA program participation. [ABSTRACT FROM AUTHOR]

This article aims to provide insights regarding crime problems affecting the Australian and New Zealand (ANZ) retail sector, focusing primarily on the size and range of criminal behaviours. The research incorporated an online survey of retailers and police statistics. The study finds that the cost of retail crime increased by 28% over the last 4 years, against 25% growth in revenue. It also reveals that shoplifting remains the most significant and costly economic problem facing retailers, followed by employee theft. Additionally, fraud, notably in online channels, will remain a concern for the foreseeable future. We examine potential explanations and interpretations for retail crime through an environmental criminological lens. Increased research and involvement of researchers hold tremendous potential for reducing retail crime and preventing its growth in the future. [ABSTRACT FROM AUTHOR]

Background: The demand for mental health services in Australia is substantial and has grown beyond the capacity of the current workforce. As a result, it is currently difficult for many to access secondary healthcare providers. Within the secondary healthcare sector, however, peer workers who have lived experience of managing mental health conditions have been increasingly employed to intentionally use their journey of recovery in supporting others living with mental health conditions and their communities. Currently, the presence of peer workers in primary care has been limited, despite the potential benefits of providing supports in conjunction with GPs and secondary healthcare providers. Methods: This stepped-wedge cluster randomised controlled trial (RCT) aims to evaluate a lived experience peer support intervention for accessing mental health care in primary care (PS-PC). Four medical practices across Australia will be randomly allocated to switch from control to intervention, until all practices are delivering the PS-PC intervention. The study will enrol 66 patients at each practice (total sample size of 264). Over a period of 3–4 months, 12 h of practical and emotional support provided by lived experience peer workers will be available to participants. Scale-based questionnaires will inform intervention efficacy in terms of mental health outcomes (e.g., self-efficacy) and other health outcomes (e.g., healthcare-related costs) over four time points. Other perspectives will be explored through scales completed by approximately 150 family members or carers (carer burden) and 16 peer workers (self-efficacy) pre- and post-intervention, and 20 medical practice staff members (attitudes toward peer workers) at the end of each study site's involvement in the intervention. Interviews (n = 60) and six focus groups held toward the end of each study site's involvement will further explore the views of participants, family members or carers, peer workers, and practice staff to better understand the efficacy and acceptability of the intervention. Discussion: This mixed-methods, multi-centre, stepped-wedge controlled study will be the first to evaluate the implementation of peer workers in the primary care mental health care sector.

Background: High stakes examinations used to credential trainees for independent specialist practice should be evaluated periodically to ensure defensible decisions are made. This study aims to quantify the College of Intensive Care Medicine of Australia and New Zealand (CICM) Hot Case reliability coefficient and evaluate contributions to variance from candidates, cases and examiners. Methods: This retrospective, de-identified analysis of CICM examination data used descriptive statistics and generalisability theory to evaluate the reliability of the Hot Case examination component. Decision studies were used to project generalisability coefficients for alternate examination designs. Results: Examination results from 2019 to 2022 included 592 Hot Cases, totalling 1184 individual examiner scores. The mean examiner Hot Case score was 5.17 (standard deviation 1.65). The correlation between candidates' two Hot Case scores was low (0.30). The overall reliability coefficient for the Hot Case component consisting of two cases observed by two separate pairs of examiners was 0.42. Sources of variance included candidate proficiency (25%), case difficulty and case specificity (63.4%), examiner stringency (3.5%) and other error (8.2%). To achieve a reliability coefficient of > 0.8 a candidate would need to perform 11 Hot Cases observed by two examiners. Conclusion: The reliability coefficient for the Hot Case component of the CICM second part examination is below the generally accepted value for a high stakes examination. Modifications to case selection and introduction of a clear scoring rubric to mitigate the effects of variation in case difficulty may be helpful. Increasing the number of cases and overall assessment time appears to be the best way to increase the overall reliability. Further research is required to assess the combined reliability of the Hot Case and viva components. [ABSTRACT FROM AUTHOR]

According to the OECD definition of innovative learning environments (ILEs), inclusion is considered a pillar of its design. The depiction of an inclusive ILE from the OECD outlines the importance of including students in ILEs. We wish to argue, however, that the successful implementation of inclusion also needs to address the location of special education teachers within these spaces. Our research provides a 'spaces of belonging' framework that offers support for the successful inclusion of special education teachers within an ILE. Results from our ILE project and interviews with special education teachers in Australia and New Zealand will illustrate the three concepts of 'spaces of belonging', using studies from a range of schools. We hope that the findings will inform future planning and design processes that will promote effective inclusive teaching practices in Australia and New Zealand. [ABSTRACT FROM AUTHOR]

This article presents global cancer statistics by world region for the year 2022 based on updated estimates from the International Agency for Research on Cancer (IARC). There were close to 20 million new cases of cancer in the year 2022 (including nonmelanoma skin cancers [NMSCs]) alongside 9.7 million deaths from cancer (including NMSC). The estimates suggest that approximately one in five men or women develop cancer in a lifetime, whereas around one in nine men and one in 12 women die from it. Lung cancer was the most frequently diagnosed cancer in 2022, responsible for almost 2.5 million new cases, or one in eight cancers worldwide (12.4% of all cancers globally), followed by cancers of the female breast (11.6%), colorectum (9.6%), prostate (7.3%), and stomach (4.9%). Lung cancer was also the leading cause of cancer death, with an estimated 1.8 million deaths (18.7%), followed by colorectal (9.3%), liver (7.8%), female breast (6.9%), and stomach (6.8%) cancers. Breast cancer and lung cancer were the most frequent cancers in women and men, respectively (both cases and deaths). Incidence rates (including NMSC) varied from four‐fold to five‐fold across world regions, from over 500 in Australia/New Zealand (507.9 per 100,000) to under 100 in Western Africa (97.1 per 100,000) among men, and from over 400 in Australia/New Zealand (410.5 per 100,000) to close to 100 in South‐Central Asia (103.3 per 100,000) among women. The authors examine the geographic variability across 20 world regions for the 10 leading cancer types, discussing recent trends, the underlying determinants, and the prospects for global cancer prevention and control. With demographics‐based predictions indicating that the number of new cases of cancer will reach 35 million by 2050, investments in prevention, including the targeting of key risk factors for cancer (including smoking, overweight and obesity, and infection), could avert millions of future cancer diagnoses and save many lives worldwide, bringing huge economic as well as societal dividends to countries over the forthcoming decades.

A report from the University of Technology Sydney discusses research findings on the use of suggested prices to enhance the profitability of pay what you want (PWYW) strategies. The study conducted five experiments to explore the impact of suggested prices on buyers' payments. The results showed that a higher suggested price led to increased payments, and this relationship was mediated by cost estimation. However, when a charitable element was present, increasing the suggested price did not stimulate higher payments. The research suggests that sellers using PWYW could use suggested prices to provide cost information, but it may not be suitable for products with a charitable component. [Extracted from the article]

This paper presents experimental and numerical investigations into the post-fire cross-section compressive behaviour and resistances of circular recycled aggregate concrete-filled stainless steel tube (RACFSST) stub columns. Twelve stub column specimens, fabricated from concretes with three recycled coarse aggregate replacement ratios (0%, 35% and 70%), were tested after exposure to the ISO-834 standard fire for 0 min (i.e. at ambient temperature), 15 min, 30 min and 45 min. The experimental investigation included heating and cooling of specimens, cylinder tests and post-fire tensile coupon tests and stub column tests. The test results, including load–end shortening curves, failure loads and failure modes, were fully reported and the initial compressive stiffnesses and confinement effect were discussed. The numerical investigation was subsequently conducted, where thermal and mechanical finite element models were developed and validated against the test results and then used to perform parametric studies to generate further numerical data. Given the absence of design codes for stainless steel–recycled aggregate concrete composite structures after exposure to fire, the relevant design rules for circular natural aggregate concrete-filled carbon steel tube stub columns at ambient temperature, as set out in the European code, Australia/New Zealand standard and American specification, were assessed, using post-fire material properties, for their applicability to circular RACFSST stub columns after exposure to fire, based on the test and numerical data. The assessment results generally revealed that the European code and the Australian/New Zealand standard led to an acceptable level of design accuracy and consistency, while the American specification resulted in rather conservative and scattered post-fire cross-section compression resistance predictions. • The compressive behaviour of circular RACFSST stub columns after exposure to fire is investigated. • Post-fire compression tests on twelve circular RACFSST stub column specimens are conducted. • The influences of heating durations and RCA replacement ratios are analysed. • Thermal and mechanical FE models are validated against test results and then used to conduct parametric studies. • The relevant design codes are assessed against the test and FE data.
