The Placenta And Cardiovascular Disease: A Meta-Analysis, Ruben Phillips

Theses: Doctorates and Masters

The uterine environment in which a fetus grows and develops is now recognised as a risk factor for the development of adult diseases such as cardiovascular disease (CVD). A fetus relies on the nutrients and conditions delivered via the placenta, and as such the placenta plays a vital role in the establishment and maintenance of appropriate uterine conditions. Unfavourable uterine conditions such as an inadequate resource flow from the placenta can lead to diminished growth of the fetus and may ultimately result in both short and long-term increases in risk of CVD for the baby. This has been demonstrated in …

The Uluru Statement: A First Nations Perspective Of The Implications For Social Reconstructive Race Relations In Australia, Jesse John Fleay, Barry Judd

Research outputs 2014 to 2021

From every State and Territory of Australia, including the islands of the Torres Strait over 200 delegates gathered at the 2017 First Nations National Constitutional Convention in Uluru, which has stood on Anangu Pitjantjatjara country in the Northern Territory since time immemorial, to discuss the issue of constitutional recognition. Delegates agreed that tokenistic recognition would not be enough, and that recognition bearing legal substance must stand, with the possibility to make multiple treaties between Aboriginal peoples and Torres Strait Islanders and the Commonwealth Government of Australia. In this paper, we look at the roadmap beyond such a potential change. We …

Olsen, Simone Strydom, Matthew W. Fraser, Elizabeth A. Sinclair, John Statton, Renae K. Hovey, Jordan A. Thomson, Derek A. Burkholder, Kathryn M. Mcmahon, Kieryn Kilminster, Yasha Hetzel, James W. Fourqurean, Michael R. Heithaus, Robert J. Orth

Research outputs 2014 to 2021

A central question in contemporary ecology is how climate change will alter ecosystem structure and function across scales of space and time. Climate change has been shown to alter ecological patterns from individuals to ecosystems, often with negative implications for ecosystem functions and services. Furthermore, as climate change fuels more frequent and severe extreme climate events (ECEs) like marine heatwaves (MHWs), such acute events become increasingly important drivers of rapid ecosystem change. However, our understanding of ECE impacts is hampered by limited collection of broad scale in situ data where such events occur. In 2011, a MHW known as the …

Barriers To Grassroots Innovation: The Phenomenon Of Social-Commercial-Cultural Trilemmas In Remote Indigenous Art Centres, Janice Jones, Pi-Shen Seet, Tim Acker, Michelle Whittle

Research outputs 2014 to 2021

Despite substantial research on grassroots innovation, there is a lack of understanding on the barriers to grassroots innovation. We examine paradoxes that arise as a consequence of multiple, often conflicting, objectives in remote art centres, social enterprises that are key sites for grassroots innovations. We investigate how social, commercial and cultural logics in remote Indigenous art centres contribute to an on-going trilemma that acts as a barrier to the development of grassroots innovation. We also explore the challenges and opportunities managers encounter in reconciling these multiple, often conflicting, logics. The results indicate that although art centres have dual social and …

Positive Veteran Teachers: Who Are They, And Where Are They To Be Found?, Geoffrey Lowe, Christina Gray, Peter Prout, Sarah Jefferson, Therese Shaw

Research outputs 2014 to 2021

Teacher career trajectory studies have identified a small group of veteran teachers who remain positive and committed to teaching, while others become disenchanted or disengaged. These, and related studies suggest key characteristics of positive veteran teachers revolve around a strong sense of agency and professional identity including: 1) a continuing desire to experiment and embrace challenges; 2) high levels of personal comfort in their teaching roles; and 3) a willingness to take on leadership roles across a range of capacities and contexts, and in turn be affirmed in these roles. While studies describe these characteristics, there has been little attempt …

Patient-Defined Meaningfulness Within Chronic Pain Rehabilitation: A Concept Analysis, Katrina Liddiard, Annette J. Raynor, Annette M. Rivard, Cary A. Brown

Research outputs 2014 to 2021

Background: As the problem of chronic pain grows worldwide, rehabilitation is critical to improved patient well-being. There is thus a need for rehabilitation-focused research. It appears that outcomes are improved when patients perceive the rehabilitation process to be meaningful. However, there is no empirical evidence determining how this would be achieved. An important first step is to identify and describe the concept of meaningfulness as it is used in the chronic pain rehabilitation literature. Objective: This paper reports the findings of a structured concept analysis to define meaningfulness from the patient perspective in chronic pain rehabilitation. Methodology: In consultation with …

Toward A Model Of Destination Resident–Environment Relationship: The Case Of Gulangyu, China, Lujun Su, Songshan (Sam) Huang, Joanna Pearce

Research outputs 2014 to 2021

This study tested an integrative model to better understand residents’ environmentally responsible behaviour (RERB) and willingness to sacrifice for the environment (WTS) using a sample of 430 residents on Gulangyu Island in China. Results show that destination environmental quality and eco-friendly reputation directly affected resident environmental identification and environmental commitment. Destination eco-friendly reputation directly influenced RERB and WTS. Both resident environmental identification and commitment directly affected RERB and WTS. Furthermore, environmental identification and environmental commitment fully mediate the effects of environmental quality on RERB and WTS, and partially mediate the effects of destination eco-friendly reputation on RERB and WTS. © …

From Socioeconomic Disadvantage To Obesity: The Mediating Role Of Psychological Distress And Emotional Eating, Jade Spinosa, Paul Christiansen, Joanne M. Dickson, Valentina Lorenzetti, Charlotte A. Hardman

Research outputs 2014 to 2021

Objective: Lower socioeconomic status is robustly associated with obesity; however, the underpinning psychological mechanisms remain unclear. The current study sought to determine whether the relationship between lower socioeconomic status and obesity is explained by psychological distress and subsequent emotional eating as a coping strategy. It also examined whether psychological resilience plays a protective role in this pathway. Methods: Participants (N = 150) from a range of socioeconomic backgrounds completed questionnaire measures of psychological distress, emotional eating, and resilience. They reported their income and education level as an indicator of socioeconomic status and their height and weight in order to calculate …

No Causal Effect Of Telomere Length On Ischemic Stroke And Its Subtypes: A Mendelian Randomization Study, Weijie Cao, Xingang Li, Xiaoyu Zhang, Jie Zhang, Qi Sun, Xizhu Xu, Ming Sun, Qiuyue Tian, Qihuan Li, Hao Wang, Jiaonan Liu, Xiaoni Meng, Lijuan Wu, Manshu Song, Haifeng Hou, Youxin Wang, Wei Wang

Research outputs 2014 to 2021

Background: Epidemiological studies observing inconsistent associations of telomere length (TL) with ischemic stroke (IS) are susceptible to bias according to reverse causation and residual confounding. We aimed to assess the causal association between TL, IS, and the subtypes of IS, including large artery stroke (LAS), small vessel stroke (SVS), and cardioembolic stroke (CES) by performing a series of two-sample Mendelian randomization (MR) approaches. Methods: Seven single nucleotide polymorphisms (SNPs) were involved as candidate instrumental variables (IVs), summarized from a genome-wide meta-analysis including 37,684 participants of European descent. We analyzed the largest ever genome-wide association studies of stroke in Europe from …

Plasma Neurofilament Light Chain And Amyloid-Β Are Associated With The Kynurenine Pathway Metabolites In Preclinical Alzheimer's Disease, Pratishtha Chatterjee, Henrik Zetterberg, Kathryn Goozee, Chai K. Lim, Kelly R. Jacobs, Nicholas J. Ashton, Abdul Hye, Steve Pedrini, Hamid R. Sohrabi, Tejal Shah, Prita R. Asih, Preeti Dave, Kaikai Shen, Kevin Taddei, David B. Lovejoy, Gilles J. Guillemin, Kaj Blennow, Ralph N. Martins

Research outputs 2014 to 2021

BACKGROUND: Blood markers indicative of neurodegeneration (neurofilament light chain; NFL), Alzheimer's disease amyloid pathology (amyloid-β; Aβ), and neuroinflammation (kynurenine pathway; KP metabolites) have been investigated independently in neurodegenerative diseases. However, the association of these markers of neurodegeneration and AD pathology with neuroinflammation has not been investigated previously. Therefore, the current study examined whether NFL and Aβ correlate with KP metabolites in elderly individuals to provide insight on the association between blood indicators of neurodegeneration and neuroinflammation.

METHODS: Correlations between KP metabolites, measured using liquid chromatography and gas chromatography coupled with mass spectrometry, and plasma NFL and Aβ concentrations, measured using …

Research outputs 2014 to 2021

Introduction: A potential link exists between prostate cancer (PCa) disease and treatment and increased inflammatory levels from gut dysbiosis. This study aims to examine if exercise favourably alters gut microbiota in men receiving androgen deprivation therapy (ADT) for PCa. Specifically, this study will explore whether: (1) exercise improves the composition of gut microbiota and increases the abundance of bacteria associated with health promotion and (2) whether gut health correlates with favourable inflammatory status, bowel function, continence and nausea among patients participating in the exercise intervention.

Methods and analysis: A single-blinded, two-armed, randomised controlled trial will explore the influence of a …

Noninvasive Diagnosis Of Irritable Bowel Syndrome Via Bowel Sound Features: Proof Of Concept, Xuhao Du, Gary Allwood, K. Mary Webberley, Andrisha-Jade Inderjeeth, Adam Osseiran, Barry James Marshall

Research outputs 2014 to 2021

INTRODUCTION: Irritable bowel syndrome (IBS) is a common and debilitating disorder estimated to affect approximately 11% of the world's population. Typically, IBS is a diagnosis of exclusion after patients undergo a costly and invasive colonoscopy to exclude organic disease. Clinician's and researchers have identified a need for a new cost-effective, accurate, and noninvasive diagnostic test for IBS.

METHODS: Using a diagnostic case-control study, we explored the use of bowel sounds to characterize IBS with a view to diagnostic use. We recruited participants with an existing clinical diagnosis of IBS or healthy (asymptomatic) digestive systems. We recorded bowel sounds for 2 …

Ladies, Gentlemen And Guys: The Gender Politics Of Politeness, Sonam Pelden, Elizabeth Reid Boyd, Madelena Grobbelaar, Kwadwo Adusei-Asante, Lucy Hopkins

Research outputs 2014 to 2021

Are there ladies and gentlemen in the 21st century? Do we need them? In the 20th century, lady became particularly unpopular with second wave feminists, who preferred ‘woman’. Gentleman was seen as similarly politically incorrect: class, race and culture bound. Following previous research on the word lady, we explore here some current evocations and debates around these words. We consider how the more casual, etymologically gendered term ‘guy’ has been utilized for men and women, and how it functions to reflect and obscure gender. While the return of the lady might be considered a consumer fad, a neo-conservative post-feminist backlash, …

How Do Librarians In Schools Support Struggling Readers?, Margaret Kristin Merga

Research outputs 2014 to 2021

While librarians in schools often face significant budgetary cuts, they can play an important role in supporting learning in literacy and literature. However, little is known about the practices that they may employ to this end. Of particular interest is the role of librarians in schools in supporting struggling readers, as these students may be increasingly disadvantaged as they move through the years of schooling. Semi-structured interview data were collected from teacher librarians at 30 schools and analysed to identify practices exercised by teacher librarians that aligned with extant research around supporting struggling readers. Teacher librarians provided support by identifying …

Teachers’ Perspectives On The Identification Of, And Provisions For, Gifted And Talented English As An Additional Language Students, Lucy Byramji Hands

Theses: Doctorates and Masters

In recent years, Western Australian State schools have seen a sharp rise in the number of students who use English as an Additional Language (EAL). Almost one-third of them have been identified as having culturally and linguistically diverse ancestry (Australian Bureau of Statistics, 2016). Many are gifted and talented (GT). However, while it has been widely acknowledged that GT abilities can be found in all ethnic, cultural, and linguistic groups, barriers such as socioeconomic circumstances, stereotypes, political climate, language backgrounds and a myriad of factors can influence the recognition, identification and full participation of EAL students in gifted and talented …

Performance Practice In Hungarian Folk Music And Its Relationship To The Style Hongrois, Teresa Vinci

Theses: Doctorates and Masters

This study investigates style and performance practice within the oral traditions of Hungarian folk music, and explores intersections with the nineteenth-century idiom style hongrois. Interviews, lessons, and workshops were undertaken as part of a practice-based immersive research experience, and comparisons with the style hongrois made via analysis of scores and recordings of Jeno Hubay (1858-1937). The research strives towards an ‘Historically Informed Performance’ specific to these styles, and explores how they can inform each other. Findings are presented through a dissertation and a CD recording “Never Far Away…” comprising the researcher’s violin performance as leader of an Hungarian folk …

Assessing Synergy Between Climate And Development Projects: Which One Is More Effective, Efficient And Transparent?, A.K. Enamul Haque, Estiaque Bari, Md Rumi Shammin

Faculty & Staff Scholarship

This study was designed to understand whether projects funded through development window of finance in Bangladesh like the Annual Development Programme(ADP) is different or similar to that of climate window of finance like Bangladesh Climate Change Trust Fund (BCCTF). The BCCTF is managed primarily by the Ministry of Environment, Forests and Climate Change whereas the ADP is managed by the Ministry of Planning and Ministry of Finance. It was, therefore, studied also to understand whether the new window of financing climate projects is more efficient, effective and sustainable. On the contrary, if they are both similar in nature then a …

Codon-Specific Translation By M1g37 Methylation Of Trna, Ya-Ming Hou, Isao Masuda, Howard Gamper

Department of Biochemistry and Molecular Biology Faculty Papers

Although the genetic code is degenerate, synonymous codons for the same amino acid are not translated equally. Codon-specific translation is important for controlling gene expression and determining the proteome of a cell. At the molecular level, codon-specific translation is regulated by post-transcriptional epigenetic modifications of tRNA primarily at the wobble position 34 and at position 37 on the 3′-side of the anticodon. Modifications at these positions determine the quality of codon-anticodon pairing and the speed of translation on the ribosome. Different modifications operate in distinct mechanisms of codon-specific translation, generating a diversity of regulation that is previously unanticipated. Here we …

Myth And Christian Reading Practice In English Teaching, Scott Jarvie

Faculty Research, Scholarly, and Creative Activity

This chapter identifies myths which hold special significance in English classrooms, and, in doing so, weave them into the otherwise conventional, well-nested, even imperial logics of English as a school subject. Barthes explains as much, arguing that myths have a social history, and are in that sense unnatural, though they operate by naturalizing. Yet English teaching and the research which undergirds it has historically sought to demystify the field, positioning its relation to myth antagonistically. The chapter focuses on myths of linguistic and grammatical instruction, which cut across the traditional domains of English teaching as well as recent curricular expansions …

Digitizing Brandenburg: Common Law Drift Toward A Causal Theory Of Imminence, J. Remy Green

Faculty Scholarship

The Supreme Court’s Brandenburg v. Ohio test provides an exception to the First Amendment’s broad guarantee of freedom of speech. Where speech is (1) directed to inciting or producing imminent lawless action, and (2) is likely to incite or produce such action, the First Amendment withdraws its promise of protection. Thus, where the “imminence” of lawless action cannot be shown, free speech cannot be restricted. Since Brandenburg, Courts have applied a test for imminence that turns on proximity in space and in time — that is, the test evaluates how spatiotemporally imminent lawless activity is. In this Article, I argue …
