Influence Of Obesity And Insulin Resistance With Hepatic Steatosis On The Human Plasma Lipidome, Max C Petersen, Gordon I Smith, Aaron M Armando, Xiong Su, Oswald Quehenberger, Edward A Dennis, Samuel Klein

2020-Current year OA Pubs

Insulin resistance accompanied by hepatic steatosis is a common complication of obesity. In an effort to identify plasma lipids that could be biomarkers or causes of insulin resistance with steatosis in people with obesity, we evaluated the plasma lipidome in three distinct groups separated by adiposity, hepatic steatosis, and insulin sensitivity, assessed by using the hyperinsulinemic-euglycemic clamp procedure: i) insulin-sensitive lean (ISL, n = 13); ii) insulin-sensitive obese (ISO, n = 14); and iii) insulin-resistant obese with hepatic steatosis (IROS, n = 13). We evaluated 759 complex lipid species in 16 subclasses (including phospholipids, glycerolipids, sphingolipids, acylcarnitines, and cholesteryl esters) …

OBJECTIVES: This study characterized the experience, confidence, willingness, and motivating factors for hematologists/oncologists to care for adults with VAs.

METHODS: We surveyed United States hematologists and oncologists in adult medicine between October 2024 and March 2025. The questionnaire assessed knowledge, experience, confidence, and willingness to care for adults with VAs, as well as open-ended questions assessing factors influencing …

Steroid Hormone Metabolites And Mammographic Breast Density In Premenopausal Women, Ghazaleh Pourali, Kayode A Matthew, Myung Sik Jeon, Chongliang Luo, Gary J Patti, Jingqin Luo, Adetunji T Toriola

2020-Current year OA Pubs

BACKGROUND: Steroid hormones influence breast morphology and cellular proliferation and are associated with breast carcinogenesis. However, their associations with mammographic breast density (MBD) are less studied, particularly in premenopausal women. We, therefore, investigated the associations of steroid hormone metabolites with MBD in premenopausal women.

METHODS: Our study included 700 premenopausal women scheduled for screening mammograms. We analyzed 54 steroid hormone metabolites (Metabolon®) and assessed volumetric measures of MBD including volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV) using Volpara. We investigated associations using linear regression modeling to estimate the covariate-adjusted means of VPD, NDV, and DV, corresponding …

Australian University Websites As Colonialities Of Gender, Emily M. Gray, Ampersand Pasley, Emma Fishwick, Mindy Blaise, Jacqueline Ullman, Maria Delaney

Research outputs 2022 to 2026

This paper offers analysis of the first phase of a research project, Understanding and Addressing Everyday Sexisms in Australian Universities. This phase involved a critical content analysis of all 39 of Australia’s public university websites, focusing on how they represent gender, absences in relation to gender and the navigability of the websites in relation to gender equity policy. Drawing on Maria Lugones’s colonialities of gender, this paper demonstrates how university websites have the potential to reproduce or renegotiate inherited institutional everyday sexisms and broader gender inequities. Themes of reconfiguring acceptable gendering, conspicuous absences, and in-built obscurity that emerged from this …

Lack Of Disparities In Postoperative Care After Ileocecal Resection In Patients With Crohn's Disease At Tertiary Inflammatory Bowel Diseases Centers, Shannon Coombs, Molly Powell, Kemmian Johnson, Jessica Hu, Mollie Webb, Philip Mcdaniel, Parakkal Deepak, Edward L Barnes

2020-Current year OA Pubs

BACKGROUND: Prior studies suggest that longer drive time (DT) to specialists and higher area deprivation index (ADI) are linked to worse outcomes in inflammatory bowel disease (IBD), but their impact on postileocolic resection (ICR) care in patients with Crohn's disease (CD) is not well defined.

OBJECTIVES: We aimed to evaluate disparities in post-ICR care based on DT and ADI.

METHODS: Spatial analysis was performed with ArcGIS Pro to geocode patient and medical facility addresses with StreetMap Premium locators. High DT was defined as >60 min from the center. Data were analyzed using basic statistics and multivariate logistic regression.

The Impact Of Fixation Method And Surgical Approach On Outcomes Following Hip Hemiarthroplasty For Femoral Neck Fracture, Brian D Rust, Mitchel R Obey, Jenna-Leigh Wilson, Christopher M Mcandrew, Marschall B Berkes

2020-Current year OA Pubs

INTRODUCTION: Hip hemiarthroplasty is commonly performed for displaced femoral neck fractures in older adults, with implants placed either cemented or uncemented. While cemented fixation offers immediate stability, uncemented fixation reduces operative time and pulmonary complications. Large single-center analyses comparing these techniques remain limited, and this study aims to assess this.

METHODS: We conducted a retrospective case-control study of 634 adult patients undergoing hip hemiarthroplasty at a single Level 1 trauma center from 2019 to 2025. Patients were classified by cemented (n=403) or uncemented (n=231) fixation and further stratified by surgical approach (anterolateral vs posterior). Outcomes included length of stay, postoperative …

2020-Current year OA Pubs

BACKGROUND: Sonobiopsy is a promising new technique that employs focused ultrasound (FUS) to noninvasively enrich brain tumor-derived biomarkers from spatially targeted brain location into the bloodstream. Building upon our recent first-in-human sonobiopsy trial demonstrating enrichment of circulating tumor DNA (ctDNA), here we investigated whether sonobiopsy can enhance the release and detection of tumor-derived microRNAs (miRNAs).

METHODS: Eleven patients with glioma underwent FUS sonication immediately prior to surgical resection. Peripheral blood samples were collected 5 min before and 5, 10, and 30 min after sonication. Plasma and brain tissue miRNA levels were quantified through small RNA sequencing and compared among different …

The study specifically examined the feasibility of using e-portfolios to facilitate quality PL learning and quality assessment in Physical Education (PE), from different stakeholder perspectives. Methods: This interpretive study employed a qualitative design and methods to investigate aspects of feasibility with three purposive participant …

The Hows And Whys Of Gendered Grouping Practices In Primary Physical Education In England, Shaun D. Wilkinson, Annette Stride, Dawn Penney

Research outputs 2022 to 2026

Background: Single- and mixed-sex grouping have long been a focus of attention in physical education (PE) and are matters often at the fore of discussions about curriculum planning, teaching, and learning. Nonetheless, there remains little consensus or guidance on which approach (or combination of approaches) should be preferred in PE in primary and secondary schools in England. Further, while single- and mixed-sex grouping have been extensively researched in PE in secondary schools, hitherto there remains an absence of research examining these practices in PE in primary schools. This research sought to address gaps in the literature to build a stronger …

Research outputs 2022 to 2026

This theoretical paper presents a heuristic framework that is directed towards transformative thinking and practices in Physical Education Teacher Education (PETE). The research focus and direction, embodying policy work, applies and extends Bernstein’s concepts of the pedagogic and corporeal device to offer new directions for inquiry and explore the considerations these raise for PETE professionals and their practices. The paper affirms the importance of policy work in PETE, while recognising a need for more nuanced and critical understandings of the complex interrelationships between contexts and actions, and the potential meanings generated and ascribed to different forms of policy work and …

A Figurational Analysis Of Health And/Or Physical Education Teacher Educators’ Conceptualisations Of Policy, And Their Sociogenesis, Laura Alfrey, Dylan Scanlon, David Aldous, Jenna Lorusso, Kellie Baker, Christopher Clark, Mo Jafar

Research outputs 2022 to 2026

Policy engagement is key to promoting quality physical education yet it has been identified as a ‘grand challenge’ for Health and/or Physical Education (H/PE) internationally. All H/PE professionals, including teacher educators, have a collective responsibility to engage with policy but existing research tells us little about how H/PE teacher educators (H/PETEs) understand and engage with policy. It is important to examine H/PETEs conceptualisations of policy for a few reasons, not least because teacher educators play a crucial role in supporting future generations of teachers who themselves will need to engage with policy as a core feature of their professional lives. …

The “Green Persuasion Effect” Of Negative Messages: How And When Message Framing Influences Tourists’ Environmentally Responsible Behavior, Xuehuan He, Chengzhi Ye, Songshan Huang, Lujun Su

Research outputs 2022 to 2026

Tourist activities may harm the environment, making tourists’ environmentally responsible behavior particularly important in tourism research. This research investigates the persuasion effect of message framing in environmental protection reminders on environmentally responsible behavior. Through five studies employing both field and controlled experiments and different measures of environmentally responsible behavior across varied tourism scenarios, we demonstrate that negatively (vs. positively) framed messages more effectively increase environmentally responsible behavior. Specifically, negatively framed messages are more effective in enhancing tourists’ environmental awareness, which triggers more environmentally responsible behavior. Furthermore, we identify social class as a moderator of message framing effectiveness, showing that negatively …

Curriculum Approaches To Strengthening Student Employability And Improving Graduate Outcomes In The Stm Disciplines, Denise Jackson, Michael D. O’Connor

Research outputs 2022 to 2026

In Australia and elsewhere, curriculum improvements are needed to improve the development of Science, Technology and Mathematics (STM) graduates for future work and careers. Several studies document significant STM student attrition, poor graduate preparedness for work, relatively weak employment rates post-graduation, and mismatched expectations of graduate capabilities by employers. The inclusion of work-integrated learning (WIL) activities within curricula can better prepare students for relevant employment by bridging discipline-specific teaching with work practices. Traditionally, access to WIL has been limited for STM Bachelor students and a better understanding of WIL’s benefits and impact is needed to refine and extend STM WIL …

Centring The Audience: Attitudes And Behaviours In Australian Arts Organisations, Katya Johanson, Abbie Trott, Mark Taylor, Anne Kershaw, Hilary Glow, Tracy Margieson

Research outputs 2022 to 2026

Many arts organisations seek to increase the diversity of their audiences. Recent literature suggests that this requires organisations to interrogate and change their ways of operating. This is a fundamental shift for a sector that has long considered the goal of diversifying audiences as a problem external to the organisation. Responding to this discrepancy, this article compares attitudes and behaviours among workers in arts organisations, to identify whether staff see the need to make change and practise the behaviours required. It identifies and uses three organisational capabilities–‘dynamic capabilities’, ‘social networks’ and ‘business improvement processes’–to frame an analysis of a national …

Research outputs 2022 to 2026

This study triangulates historiographical and scientometric reviews to provide a systems perspective on film tourism. The three phases of historiographical analysis (exploration, growth, and maturity) correspond to the three clusters of scientometric analysis: (i) initial research exploring film tourism development and management, (ii) growing the field through studies on film tourists’ perceptions and practices, and (iii) reaching maturity through extending research into different cultural contexts and meaning-making processes. Based on the analysis, we offer a set of directions for future research, including the need to integrate sustainability research and film tourism studies in developing country contexts, as well as intertextuality …

School Library Professionals’ Perspectives On Current And Future Workforce Challenges, Margaret Kristin Merga, Saiyidi Mat Roni

Research outputs 2022 to 2026

While school library professionals work across many nations, supporting student learning and wellbeing, there is limited current research capturing shared issues faced by this educational workforce. The International School Library Workforce Survey collected insights from 971 respondents across 63 countries derived from analysis of both quantitative and qualitative data. Findings suggest that in an international context, school library professionals are experiencing notable issues that impact upon their morale and their ability to enact their professional roles. Respondents were more likely to disagree then agree that school library professionals were typically valued in their country. While the vast majority of respondents …

Crisis Planning Intentions Among Hotel Managers: What Have We Learned From The Covid-19 Pandemic?, Feliani Tjong, Edmund Goh, Violetta Wilk

Research outputs 2022 to 2026

This study investigates the motivational factors which influence future crisis planning intentions, by utilising the Theory of Planned Behaviour (TPB) as the underlying theoretical framework. This research focuses on understanding the attitudes, subjective norms, and perceived behavioural control of hotel managers’ intentions regarding future crisis planning. To enhance the TPB model, the study incorporates two additional variables: perceived risk and past behaviour, thereby addressing previous calls to extend the TPB model. Employing a qualitative methodology, semi-structured interviews (n = 21) were conducted with hotel managers who worked at government-appointed quarantine hotels in Australia during the COVID-19 pandemic. Thematic analysis was …

Reflections From A Community Capacity Building Forum To Support People Bereaved By Suicide, Colleen Carlon, Jacquie Tarrant, Marie Eckersley, Priscilla Vindin

Research outputs 2022 to 2026

An estimated half the population may be impacted by suicide loss. The combination of grief and trauma makes the experience particularly complex. Recognised as the most stigmatised of all sudden losses people bereaved by suicide are in sociocultural contexts that disrupt constructive grief processes and create barriers for help seeking and supportive responses. Effecting change in this context poses a significant health promotion challenge. Social workers in the South West Region of Western Australia sought to develop and deliver a unique postvention approach aimed at strengthening the self-support capacity of people bereaved by suicide while building broader community capacity for …

Antecedents Of Emergency Services’ Street Level Bureaucrats’ (Slbs) Delivery Of Public Value: An Exploratory Study, Yvonne Brunetto, Ben Farr-Wharton, Aglae Hernandez Grande, Fleur Sharafizad, Matthew Richman

Research outputs 2022 to 2026

Street Level Organisations (SLOs) determine the Psychosocial Safety Climate (PSC) in their workplaces and we examine pathways from SLBs’ PSC and Public Service Motivation (PSM) to discretionary power, work stress, wellbeing and the subsequent delivery of public value. The structural equation modelling results from 195 Australian police, fire, ambulance, and emergency services workers indicate that PSC had a more significant role in explaining SLBs’ delivery of public value compared with PSM. The implication is that SLOs’ management must ensure psychosocially safe and supportive workplaces conducive to building SLBs’ wellbeing, because that is the pathway for delivering public value.

Nation, Nature And Childhood In Five Curricula: Towards Earthly Education, Zsuzsa Millei, Katarzyna Gawlicz, Lucy Hopkins, Camilla Eline Andersen, Danielle Ekman Ladru

Research outputs 2022 to 2026

This article explores the relations between nation, nature and childhood in five early childhood education curricula in the Nordic, post-socialist and settler-colonial states with the focus on the role education plays in the face of the climate crisis. The authors identify three interconnecting themes in which nation, nature and childhood are entangled in these curricula: 1) national nature as an object of learning; 2) nature and home/birth land and Country; and 3) stewardship for national nature. Exploring these themes from the perspective of alternative pedagogies developed to address the child–nature relations during the Anthropocene, the authors argue that these notions …

The project promotes international engagement across diverse sites, with sessions in classes centred around storytelling and story-making across a range of countries. Using vignettes, the study explored how involvement in the project presented additional opportunities for personal and professional learning for the PSTs through interacting with the diverse international settings. We considered the learning opportunities from such international online engagement, the usefulness of expanded opportunities for professional practice and how Zoom enabled …

Persistence Of Contested Value Cocreation Practices, Kim Feddema, Kaisa Koskela-Huotari, Paul Harrigan

Research outputs 2022 to 2026

The climate crisis and other global challenges make it clear that not only are new value cocreation practices (VCPs) needed, but some current VCPs must be discontinued. Prior service literature assumes that VCPs can be disrupted by reforming the institutions that govern them. However, empirical observations show that VCPs may persist even when targeted by institutional work, and recent organizational research points to contested practices that continue to be enacted even when challenged or criticized. To understand this phenomenon in value cocreation, we conducted an embedded case study of exotic pet-keeping—a set of VCPs that continue despite intervention efforts. Our …

Pre-Service Teachers’ Self-Perceptions Of Relationship Skills For Future Work In Schools, Melissa Newberry, Elizabeth B. Hinchcliff, Chelsea Cole, Michael Richardson

Australian Journal of Teacher Education

This study focuses on the perceptions pre-service teachers hold about their own abilities to form relationships with four stakeholders of schools: students, parents, teachers and administrators. Survey data from 257 students enrolled in teacher preparation programs in a mid-sized, private university in the Western US were collected, including their beliefs about relationship skills, experience with children/youth, and conceptions of relationship formation as practicing teachers. Results indicate high confidence in relationship skills, yet few ideas on how to translate those into action when it comes to forming professional relationships. These findings suggest that pre-service teachers may be underprepared regarding the relational …

From Plans To Practice: Preservice Mathematics Teachers' Journey To Conceptual Understanding, Rolando B. Magat Jr

Australian Journal of Teacher Education

This study examines the journey of preservice mathematics teachers (PMTs) in the Philippines from lesson planning to classroom practice, focusing on fostering conceptual understanding. Using a case study approach, data were gathered from 15 PMTs in Metro Manila through semi-structured interviews, classroom observations, and lesson plan analysis. Findings reveal that PMTs face challenges in deep content knowledge, effective instructional strategies, and real-world application, often prioritizing procedural knowledge over conceptual depth. Additionally, engagement strategies and resource integration were key themes influencing lesson planning. To address these gaps, the study proposes Project M.A.S.T.E.R (Mathematics Application and Strategy Training for Enhanced Readiness), a …

Australian Journal of Teacher Education

This paper examines the impact of Generative AI (GenAI) on pre-service teachers (PSTs) and its future role in Initial Teacher Education (ITE) courses. Drawing from a polychronic and polyphonic research methodology (Jandric et al., 2019; Matusov et al., 2019), the six participants, experienced Initial Teacher Educators, identify the opportunities GenAI offers for enhancing teaching, streamlining administration, and providing personalized learning. They also articulate the challenges GenAI presents: bias, ethical and authenticity issues and copyright. The Teacher Educators agree that PSTs must become technically proficient and critically discerning towards GenAI content, and they highlight the need for personalized and context-specific assessment …

Indicators Of Mid-Career Teacher Quality Through Perspectives Of Key Stakeholders, Maria Azfar Karimullah, Wayne G. Cotton, Louisa Peralta

Australian Journal of Teacher Education

The ongoing quest of quality education has focused on teaching quality in K-12 classrooms globally, as evidenced by recent research, reviews, and media coverage. Yet, identifying, defining, and measuring ‘teacher quality’ remains a complex challenge, particularly during the crucial mid-career stage. The focus on mid-career teachers in educational research is often neglected, when compared with early career teachers or teachers in leadership. This qualitative study explores the characteristics that mid-career teachers, teacher leaders and accreditation personnel perceive as the indicators of a quality mid-career teacher. Drawing on semi-structured interviews with 29 participants including 23 mid-career teachers, five school principals, and …
