Sonography is a highly specialized diagnostic imaging profession facing significant workforce challenges due to increased service delivery demands and a shortage of clinical training opportunities. Developing sustainable solutions is crucial for workforce growth. Using examples from the Australian workforce and education context, this paper explores the current sonography training pathways available and the benefits and challenges of each, highlighting the importance of work-integrated learning (WIL) in facilitating the development of professional identity, clinical competence and the quality of sonographer education. Conclusions are drawn that WIL is integral to the future of the sonography profession to improve patient outcomes and address workforce shortages. However, effective implementation requires careful planning and consideration of many factors, including regulatory requirements, industry partnerships, student and supervisor/tutor support, and issues related to equitable access and participation in WIL. Key recommendations are provided to encourage ethical student learning, university-industry collaboration, effective resource allocation, and WIL-specific research.

This is a longitudinal study to investigate whether there is a correlation between the methods for completion of homework and the incentive levels with academic achievement. The method adopted in this study is the t-test statistical analysis to assess the relationship between the use of compulsory homework on achievement and the influence of intervening and moderating variables. The findings are as follows -- Cohort 1 which completed homework in the traditional pen and paper style (with a mean of 13.278) performed better than the Cohort 2 which completed homework online They also performed better than Cohort 2 which completed homework online (with a mean of 11.851). Cohort 3 that had no incentive and subsequently no compulsion to do the homework (with a mean of 11.851) performed better than Cohort 2 which completed homework online (with a mean of 9.658).

The aim of the present study is to reconcile previous findings (a) that testing mode has no effect on test outcomes or cognitive load (Comput Hum Behav 77:1-10, 2017) and (b) that younger learners' working memory processes are more sensitive to computer-based test formats (J Psychoeduc Assess 37(3):382-394, 2019). We addressed key methodological limitations in past cognitive load research by employing a repeated measures design with 263, year 9 (aged 13-14) science students in Western Australia. Question difficulty (intrinsic cognitive load) and test mode (extraneous cognitive load) were manipulated to measure changes in test performance, cognitive load and scratch paper use on equivalent paper and computer-based versions of an Ohm's Law revision quiz. Hierarchical linear modelling indicated significantly higher paper-based test performance on difficult questions in addition to greater cognitive load and scratch paper use for all paper questions. Testing mode effects on test score, as well as both measures of cognitive load, were not significant when controlling for working memory capacity, although the testing mode*question difficulty interaction remained significant. Together, these results contradict previous findings that computer-based testing can be implemented without consequence for all learners. With the increased use of computer-based testing in national and international-level assessments, these findings warrant further research into the effect of different testing modes on school-aged students.

Martin Davies' paper seeks to vindicate the efforts of the Ramsay Centre to fund courses in 'Western Civilisation' at selected Australian universities. He begins by lamenting the rejection of vast amounts of philanthropic money for the humanities, and all too quickly dismisses the stated grounds for the Australian National University's decision to decline a deal with the Ramsay Centre: 'The issue of academic autonomy has been raised as a reason, but this is, at best, ostensible', Davies writes. He then goes on to defend the concept of courses in Western civilisation more generally. This article will briefly address a number of relevant points in reaction to Martin Davie's paper: (1) the concept 'Western Civilisation' has its own, comparatively recent, history, and needs to be viewed in its own historical context; (2) the term 'civilisation' has relatively little utility as a unit of scholarly analysis; (3) proponents of an academic program on (or for) 'Western Civilisation' are operating with a reified and artificially unified concept that breaks up under closer examination; and (4) that some of the advocacy for a 'Western Civilisation' program betrays an animus against the modern, secular, public university.

The increasing inclusion of students with disabilities in regular classes still leads to debate and many advocate for full inclusion of all students. Arguments for full inclusion are generally rights-based, but proponents also claim research supports the effectiveness of full inclusion over specialist provision for all students with disabilities. In this article, we analyse and critique the use of the research literature in an Australian advocacy paper as an example of the broad claims made concerning full inclusion. We examine the extent to which the sources used provide conclusive evidence about the merits of full inclusion. We find the advocacy paper relies heavily on opinion and non-peer-reviewed literature, with little use of quantitative research that compares outcomes for students in different settings. We suggest that policymakers should treat the conclusions drawn in this paper cautiously and give due consideration to the literature that is not supportive of full inclusion.

On 7 September 1847, in Melbourne in the Port Phillip District of the Colony of New South Wales, David John Thomas (1813-1871) presented a paper, 'On the inhalation of the vapour of Æther, with cases', at an ordinary monthly meeting of the Port Phillip Medical Association. This is the earliest known presentation of a paper on etherisation in Australia. The partial publication of the manuscript in October 1847 in the Australian Medical Journal may have led to it being returned to Thomas in Melbourne. The handwritten manuscript is now preserved in the Medical History Museum, University of Melbourne, Melbourne, Victoria. A transcript of the complete manuscript is now recorded with relevant historical notes., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Several researchers have noted how children's whole number schemes can interfere with their efforts to learn fractions. An Australian study found that children who were successful with the solution of rational number tasks exhibited greater whole number knowledge and more flexible solution strategies. Behr and Post (1988) indicated that children needed to be competent in the four operations of whole numbers, along with an understanding of measurement, for them to understand rational numbers. This paper describes a "hands on" approach developed by researchers that focuses on the use of paper folding, fraction walls and number lines to develop an understanding of fractions using a measurement model.

This paper examines the personal and professional experiences of the five arts leaders who co-wrote the foundation document for Australia's first national curriculum in the Arts. Their personal and professional backgrounds, which were explored during in depth interviews, drove the complex collaborative process that informed the first iteration of the "Australian Curriculum: The Arts." Though each couched their responses in the context of their background and arts discipline, they shared an awareness of the important role of the Arts in providing the analytical tools for children and young people to identify and subsequently challenge social injustice. The findings, which are presented as a group narrative using a Narrative Inquiry approach, reveal how the five arts leaders' individual lived experience, disciplinary experience and expertise, and commitment to collaborative leadership informed their approach. It was one driven by their shared belief that all Australian students, regardless of their background, are entitled to a quality arts education.

• Water retention curves (WRCs) of municipal solid wastes (MSWs) • Hysteresis of WRCs of MSWs with decomposition. • Effects of decomposition and paper content on the WRCs. • Unsaturated hydraulic and gas conductivity of MSWs. This paper investigates the drying and wetting water retention curves (WRCs) of municipal solid wastes (MSWs) with different paper contents, dry unit weights and degrees of biodegradation (DOBs). Fresh synthetic samples were prepared based on the field composition of the MSWs at Mugga Lane Landfill, the Australian Capital Territory (ACT), Australia. The degraded samples were prepared in simulators with MSWs of different initial dry unit weights and decomposition periods with leachate recirculation. The water retention curves (WRCs) of the MSWs were determined using pressure plate tests, in both drying and wetting phases. The outflow from MSWs was analysed using Gardner's method to obtain the unsaturated hydraulic conductivity. The results indicate that the WRCs of the MSWs are greatly affected by the DOB, paper content and dry unit weight. When DOB < 30 %, as DOB increases, the air-entry pressure of MSWs with paper increases, and the residual moisture content decreases regardless of paper content. With DOB > 30 %, the air entry pressure and residual water content depend on the balance between organic matter and highly decomposed organic constituents. The paper content affects the WRCs of MSWs due to its water retention capacity and change in the particle size distribution with decomposition. The increase in the dry unit weight of MSWs significantly increases the air entry pressure and residual moisture content, similar to the borehole samples with combined effects of biodegradation and increase in stress level from literature. Hysteresis effects have been observed during the drying and wetting of MSWs. The hysteresis of WRCs increases with the paper content and DOB. [ABSTRACT FROM AUTHOR]

The purpose of this article is to describe a couple of challenging mathematical problems that involve paper folding. These problem solving tasks can be used to foster geometric and algebraic thinking among students. The context of paper folding makes some of the abstract mathematical ideas involved relatively concrete. When implemented appropriately these activities have the potential to address many of the mathematical proficiencies, as delineated by Australian Curriculum and Assessment Reporting Authority (ACARA, 2014). [This paper was first published in the "Australian Senior Mathematics Journal," in 2014 (EJ1093386).]

Introduction: We report an investigation on collaboration practices in research papers published in the most prestigious English-medium astrophysics journals. Method: We propose an evaluation method based on three numerical indicators to study and compare, in absolute terms, three different types of collaboration (international, national and local) and authors' mobility on the basis of co-authorship. Analysis: We analysed 300 randomly selected research papers in three different time periods and used the student's t-test to determine whether the paired two-sample differences observed were statistically significant or not. Results: International collaboration is more common than national and local collaboration. International, national and local authors' mobility and intra-national collaboration do not seriously affect the indicators of the principal levels of collaboration. International collaboration and authors' mobility are more relevant for authors publishing in European journals, whereas national and intra-national collaboration and national mobility are more important for authors publishing in US journals. Conclusions: We explain the observed differences and patterns in terms of the specific scope of each journal and the socio-economic and political situation in both geographic contexts (Europe and the USA). Our study provides a global picture of collaboration practices in astrophysics and its possible application to many other sciences and fields would undoubtedly help bring into focus the really big issues for overall research management and policy.

This paper examines the Australian Defence Strategic Review (DSR) released in April 2023, focusing on the broader geopolitical trends in the Indo-Pacific Region and how it supports the United States' strategy vis-a-vis China. Australian defence strategy has historically been on the premise that Australia's security is best ensured by the presence of a reliable, established, and powerful ally, which involved sending our defence forces for overseas wars and conflicts (forward defence); and the traditional defence approach to defend the nation's borders and their approaches (Defence of Australia). The author opines that the DSR addresses both concepts. [ABSTRACT FROM AUTHOR]

The "National Mathematics Curriculum Framing Paper" has been released for consultation until 28 February 2009 (see www.ncb.org.au). Professional associations, teachers, teacher educators and others are taking the opportunity to organise meetings and forums to consider the views presented in the paper and to provide critical feedback and commentary on the proposed broad directions. The University of Sydney held a National Curriculum Symposium in December to bring together teachers, school system personnel, academics and representatives from the National Curriculum Board to have a "robust and broad ranging discussion" about the four framing papers released by the NCB: English, Mathematics, History and the Sciences. The program for the symposium began with a presentation by Professor Kerry Kennedy about his reflections on national curriculum in Australia over the last 30 years. This was followed by brief presentations by each of the authors of the framing papers. Discussion groups for each of the disciplines considered key questions about the papers with feedback from each group. Finally Rob Randall, the acting Director of the NCB commented on the challenges identified by the discussion groups. In this paper, the author summarises the comments and discussion about curriculum development in general and the "National Mathematics Curriculum Framing Paper" in particular.

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.)

Introduction Roll-your-own (RYO) tobacco is a popular choice in Australia, with some people who smoke finding these products more attractive than factory-made cigarettes (FMC). Differences in visual and tactile properties and in the feel and taste of the smoke may contribute to this attractiveness. These differences may be driven by variation in tobacco constituents and wrapping paper permeability. However, to date, there has been no comparison of RYO and FMC products on the Australian market. Aims and Methods Chemical constituents, pH, flavorants, and paper permeability were compared in unburned RYO tobacco and tobacco from FMC. RYO and FMC products from matched brands were compared, as were products from the most popular FMC and RYO brands on the Australian market in 2018. Results RYO tobacco had higher moisture and humectant content (glycerol and propylene glycol) than FMC tobacco. RYO tobacco also had higher amounts of total and reducing sugars and lower nicotine when comparing the most popular brands. RYO papers were less permeable than FMC papers. Both RYO and FMC tobacco contained many chemicals identified as flavorants, including fourteen with known potential health risks. For most measured constituents and flavorants, RYO tobaccos had more in common with other RYO than FMC, with the commonalities remaining even when matched brands were compared. Conclusions Higher levels of moisture, humectants, and sugars in Australian RYO tobacco compared to FMC may be increasing attractiveness of RYO by reducing the harsh taste of the smoke and increasing the moist feel of the tobacco. Implications While price is the main factor driving the use of RYO tobacco, some people who smoke find these products more attractive. This study has shown that Australian RYO tobacco contains higher amounts of glycerol, propylene glycol, and sugars than FMC. These chemicals may be improving the taste of the tobacco, as well as creating a moist feel that is falsely perceived as indicating that the tobacco is "fresh" and "less chemically." Ironically, it may be that higher amounts of some added chemicals in RYO contribute to false perceptions of a more natural and less harmful product. [ABSTRACT FROM AUTHOR]

"Hitler Youth Quex: A Guide for the English-Speaking Reader" is a book by William Gillespie that explores the infamous propaganda film made during the early years of the Nazi regime. The book provides new insights into the film and its historical context, drawing from the author's extensive collection of German film materials. While the book primarily focuses on the German perspective, it offers valuable primary sources and encourages critical examination of the topic. It is recommended for scholars and students studying film history, propaganda, or German Third Reich cinema. [Extracted from the article]

Institutional graduate capabilities and discipline threshold learning outcomes require science students to demonstrate ethical conduct and social responsibility. However, the teaching and assessment of these concepts are not straightforward. Australian chemistry academics participated in a workshop in 2013 to discuss and develop teaching and assessment in these areas, and this paper reports on the outcomes of the workshop. Controversial issues include: How broad is the mandate of the teacher, how should the boundaries between personal values and ethics be drawn, and who determines what constitutes social responsibility? In this position paper I argue for a deep engagement with ethics and social justice, achieved through case studies and assessed against criteria that require discussion and debate. Strategies to effectively assess science students' understanding of ethics and social responsibility are detailed.

Touch screen tablets are being increasingly used in schools for learning and assessment. However, the validity and reliability of assessments delivered via tablets are largely unknown. The present study tested the psychometric properties of a tablet-based app designed to measure early literacy skills. Tablet-based tests were also compared with traditional paper-based tests. Children aged 2-6 years (N = 99) completed receptive tests delivered via a tablet for letter, word, and numeral skills. The same skills were tested with a traditional paper-based test that used an expressive response format. Children (n = 35) were post-tested 8 weeks later to examine the stability of test scores over time. The tablet test scores showed high internal consistency (all a's > 0.94), acceptable test-retest reliability (ICC range = 0.39-0.89), and were correlated with child age, family SES, and home literacy teaching to indicate good predictive validity. The agreement between scores for the tablet and traditional tests was high (ICC range = 0.81-0.94). The tablet tests provides valid and reliable measures of children's early literacy skills. The strong psychometric properties and ease of use suggests that tablet-based tests of literacy skills have the potential to improve assessment practices for research purposes and classroom use.

Like the vast majority of Australian universities, Flinders University (Flinders) collects feedback from students on the quality of teaching and learning through unit of study (topic) or classroom evaluations. Prior to 2009, survey instruments at Flinders were delivered via paper mode and in person to students in the classroom. In a drive for an improvement to administrative efficiency, the adoption of a new system in 2009 created the option of two modes of delivery. Instruments can now be delivered via either paper mode in class, identical in most aspects to the previous system, or online mode, where students fill out the survey instrument, typically outside of class, using the World Wide Web. The choice of delivery mode is at the discretion of the academic. Students have no choice; they receive the survey either via paper or online. This article examines a number of aspects of this change in process at Flinders. Some general aspects of managing the implementation of the new process are discussed. Take-up rates of paper mode versus online mode show that the overwhelming majority of surveys were conducted online in 2009. A dramatic increase in the volume of surveying was noted. Response rates fell by approximately 20% overall and some evidence of a change in the level of response was apparent (cause unknown). Findings at the institution and faculty level are presented where applicable.

Panic buying of toilet rolls in Australia began in early March 2020. This was related to the realisation that the novel coronavirus was spreading across the country. To the general population the impact of the virus was unknown. Gradually the federal government started closing the country's borders. The panic buying of toilet rolls was not unique to Australia. It happened across all societies that used toilet paper rather than water to clean after defecation and urination. However, research suggests that the panic buying was most extreme in Australia. This article argues that the panic buying was closely linked to everyday notions of Western civilisation. Pedestal toilets and toilet paper are key aspects of civilisation and the fear of the loss of toilet paper is connected to anxiety about social breakdown, the loss of civilisation. This is the fear manifested in the perceived threat posed by the virus. [ABSTRACT FROM AUTHOR]

The Australian Science Teachers Association offers an innovative international professional development program for science teachers called the Science Teachers Exchange -- Japan. The program offers Australian and Japanese teachers an opportunity to travel to the corresponding country, allowing the teachers to grow in their knowledge of the culture and teaching practices of that country and potentially develop national and international networks. The article herein was written by Takeshi Tsuji, an elementary teacher from Tokyo, who participated in the 2017 Exchange program to Australia. As part of this program, Tsuji visited Mudgeeraba Creek State School on the Gold Coast, where he observed a fifth grade STEM lesson taught by STEM science teacher Megan Hayes, and later taught a lesson to the same class. On entering Hayes' classroom, Tsuji immediately noticed a large poster with the word 'FAIL' on it; an acronym standing for 'First Attempt In Learning'. It translates to "failure = first step in learning," meaning that learning starts from failure. This [unedited] translation of the article -- taken from a Japanese equivalent to "Teaching Science" -- takes on the theme of how students face failure and how teachers can deepen classroom learning with this acronym in mind.

Mothers play a key role in scaffolding children's writing using traditional tools, such as paper and pencil. However, little is known about how mothers scaffold young children's writing using touch-screen tablets (e.g., iPads) and the associations between maternal scaffolding and emergent literacy. Mother-child dyads (N = 47; M child age = 3.43 years) were video recorded as they wrote words using an iPad and a paper and pencil. Maternal print and grapho-phonemic mediation behaviors were measured. Children were assessed on letter name and letter-sound knowledge, letter writing and name writing, and print concepts. No significant differences were found in the level of maternal mediation provided in the tablet or paper-pencil condition. Maternal print mediation was positively associated with letter name and letter-sound knowledge and emergent writing in the tablet and paper-pencil conditions. Grapho-phonemic mediation was significantly related to children's understanding of letter-sound correspondence and print concepts in the paper-pencil condition, but not the tablet condition. Supporting parents in using grapho-phonemic mediation during tablet use to foster early literacy learning should be considered in future research.

Objectives: Current mental health practices for people living in residential aged care (RAC) facilities are poor. In Australia, there are no mechanisms to monitor and promote mental health for people living in RAC, including those who experience changed behaviours and psychological symptoms. The aim of this study is to improve current practices and mental health outcomes for people living in RAC facilities by codesigning a Mental Health benchmarking Industry Tool for residential aged Care (MHICare Tool)., Methods: A two-stage sequential and mixed methods codesign methodology will be used. Stage 1 will include qualitative interviews and focus groups to engage with residents, family/care partners and RAC staff to ascertain mental healthcare practices and outcomes of greatest significance to them. Adapted concept mapping methods will be used to rank identified issues of concern in order of importance and changeability, and to generate draft quality indicators. Stage 2 will comprise a Delphi procedure to gain the wider consensus of expert panel views (aged care industry, academic, clinical) on the performance indicators to be included, resulting in the codesigned MHICare Tool., Ethics and Dissemination: This study has been reviewed and approved by the University of Queensland Human Research Ethics Committee (HREC/2019002096). This project will be carried out according to the National Statement on Ethical Conduct in Human Research (2007). The study's findings will be published in peer-reviewed journals and disseminated at national and international conferences and through social media., Conclusion: This protocol reports structured methods to codesign and develop a mental health performance indicator tool for use in Australian RAC., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

The National Career Development Strategy Green Paper is a discussion paper issued by the Department of Employment, Education and Workplace Relations. It is aimed at the formulation of a coherent and structured career development strategy throughout Australia. The Green Paper seeks to lay the foundation for policy change through establishing the importance of career development for Australia. It outlines some priorities for implementation and was released for comment in June 2012. This article presents the author's comment to the Green Paper. The author outlines challenges faced by the Green Paper, and provides some historical background and a personal reflection. The comments that are made are subjective and based on involvement in vocational guidance and research since 1976 and private practice since 1989. Naturally the comments are limited by the time and resources available. No claim is made that the analysis is complete. (Contains 2 tables.)

Introduction: One in six people live with disability in Australia with higher levels of disability of people from diverse communities, such as those with culturally and linguistically diverse (CALD) backgrounds. In Australia, CALD refers to people from diverse ethnicity and cultures, nationalities, societal structures and religions that may or may not speak a language other than English. This study employs researchers with lived experience of disability and peer support to study the impact of peer support for people with disability, including people from CALD backgrounds, in two peer-led organisations in New South Wales (NSW) Australia., Methods and Analysis: This study uses participatory action research and inclusive research design with researchers with lived experience, having lived experience of disability and a peer in the disability community, leading the research.Over three years, three different groups will be recruited through Community Disability Alliance Hunter (CDAH) and Diversity and Disability Alliance (DDAlliance): (1) peers with disability, (2) peer leaders with disability and (3) researchers with lived experience of disability and peer support. Data collection and creation methods include semistructured interviews, surveys and focus groups. Qualitative data will be analysed using thematic analysis through the lens of the researchers with lived experience., Ethics and Dissemination: Ethical approval was granted by the University of Newcastle Human Research Ethics Committee (Approval No: H-2021-0088). Dissemination includes peer-reviewed publications, presentations at local, national and international conferences and written reports for user-led organisations, disability service providers, disability agencies and people with disability., Competing Interests: Competing interests: All authors have completed the ICMJE uniform disclosure at http://www.icmje.org/disclosure-of-interest/ and declare: financial support for the submitted work from the Australian Government Department of Social Services, Information Linkages and Capacity Building Program; MT has received an honorarium from DDAlliance and CDAH for academic input; CH was a consultant contracted by DDAlliance and CDAH to be a research adviser and project manager; JD, JM, DY, CW and FR were paid a casual salary as researchers with lived experience from DDAlliance; SP, AF, SS and OB-P were paid a casual salary as researchers with lived experience from CDAH., (© Author(s) (or their employer(s)) 2023.

Rationale: Saliva as a sample matrix is rapidly gaining interest for disease diagnosis and point-of-care assays because it is easy to collect (non-invasive) and contains many health-related biomarkers. However, saliva poses particular problems relative to more common urine and blood matrices, which includes low analyte concentrations, lack of understanding of biomolecule transportation and inherent viscosity variability in human samples. While several studies have sought to improve assay sensitivity, few have addressed sample viscosity specifically. The goal of this study is to minimize the effect of sample viscosity on paper-based analytical devices (PADs) for the measurement of pH and nitrite in human saliva. Methods: PADs were used to measure salivary pH from 5.0 to 10.0 with a universal indicator consisting of chlorophenol red, phenol red and phenolphthalein. Nitrite determination was performed using the Griess reaction. Artificial saliva with viscosity values between 1.54 and 5.10 mPa∙s was tested on the proposed PAD. To ensure the proposed PADs can be tailored for use in-field analysis, the devices were shipped to Australia and tested with human specimens. Results: Initial experiments showed that viscosity had a significant impact on the calibration curve for nitrite; however, a more consistent curve could be generated when buffer was added after the sample, irrespective of sample viscosity. The linear range for nitrite detection was 0.1 to 2.4 mg/dL using the improved method. The nitrite measurement in artificial saliva also showed a good correlation with the standard spectrophotometry method ( p =0.8484, paired sample t -test, n=20). Measured pH values from samples with varying viscosities correlated well with the results from our pH meter. Conclusions: The inherent variation of salivary viscosity that impacts nitrite and pH results can be addressed using a simple washing step on the PAD without the need for complex procedures., Competing Interests: Competing Interests: The authors have declared that no competing interest exists.
