Retired Indigenous And Non-Indigenous College Student Athletes' Mental Health Relating To Athletic Identity, Cultural Identity, And Career Transition, Victoria Williams

Theses and Dissertations

To date, empirical studies have investigated the transition or retirement phase, following the conclusion of a student-athletes’ four-year career as a comparison between student-athletes and non-athletes. Specifically, when investigating these constructs, researchers have failed to thoroughly investigate the role cultural identity may play in mitigating psychological symptoms during the transition phase. As such, this study will seek to investigate both Indigenous and non-Indigenous retired college student- athletes, during the transition phase, in terms of the degree to which they identified with their athletic identity, cultural identity and career transition. It is expected those retired Indigenous and non-Indigenous student- athletes who …

Development Of Silicon-Based Anodes With Coal-Derived Materials For High-Performance Lithium-Ion Batteries, Shuai Xu

Theses and Dissertations

The increasing demands on high energy density and long cycling life in electronics and energy storage systems require lithium-ion batteries (LIBs) with higher capacity anodes to replace the present commercial anode, graphite, which has a limited capacity of only 372 mAh g-1. Silicon-based materials (silicon and silicon suboxides) are among the most attractive alternative because of their high theoretical capacity but can hardly reach commercialization due to numerous technical and engineering barriers. The effort in this dissertation focuses on improving the electrochemical performance of SiO and Si anode materials, trying to pave a way to a greener and cleaner energy …

Translocation Of Yops By Yersinia Pestis Into Canine Cell Lines, Betsy Louise Young

Theses and Dissertations

Yersinia pestis, the causative agent of plague, secretes a set of virulence proteins called Yops when in contact with eukaryotic cells. A subset of these Yops is translocated directly into the cytosol of the host eukaryotic cells by the type III secretion system. Using a protein tag-based reporter system, this study is focused on the translocation of these Yops into the cytosol of canine derived cell lines: MDCK and DH82. The MDCK cell line is a canine derived epithelial cell line, and the DH82 cell line is a canine derived monocyte cell line. The reporter system uses a phosphorylatable peptide …

Research outputs 2022 to 2026

Establishing reliable, clean, and inexpensive solar PV systems is a complex interplay between the level of reliability (LPSP), financial constraints, and CO2 emissions. This paper investigates the impact of these factors on stand-alone (SA) and grid-supplemented (GS) solar PV systems over multiple seasons. The research uses established hardware models, detailed power management strategies as well as realistic Australian grid tariffs and Genetic Algorithms to find the minimum Cost of Energy (COE) subject to LPSP and financial constraints. The developed power management strategies are also tested experimentally on a real solar PV system. The results indicate that the grid-supplemented system yields …

Towards A Digital Twin For Characterising Natural Source Zone Depletion: A Feasibility Study Based On The Bemidji Site, Kaveh Sookhak Lari, Greg B. Davis, John L. Rayner

Research outputs 2022 to 2026

Natural source zone depletion (NSZD) of light non-aqueous phase liquids (LNAPLs) may be a valid long-term management option at petroleum impacted sites. However, its future long-term reliability needs to be established. NSZD includes partitioning, biotic and abiotic degradation of LNAPL components plus multiphase fluid dynamics in the subsurface. Over time, LNAPL components are depleted and those partitioning to various phases change, as do those available for biodegradation. To accommodate these processes and predict trends and NSZD over decades to centuries, for the first time, we incorporated a multi-phase multi-component multi-microbe non-isothermal approach to representatively simulate NSZD at field scale. To …

Geostatistical Tools To Assess Shifts In Recreational Fishing, Shannon J. Burchert, Glenn A. Hyndes, Karina Ryan, Ute Mueller

Research outputs 2022 to 2026

The use of geostatistical indices to examine fishery-dependent data over time is novel. We assess the value of a range of these indices for describing trends in boat-based recreational fishing in Western Australia and areas of high effort and catches for two demersal species with varying biological characteristics, life histories and distributions. The number of blocks (10- × 10-nautical mile (~19- × 19-km) area) visited decreased by 40%, while the number of fishing trips with demersal species catch increased by 15%. Spatial indices showed a south-easterly shift in demersal catch per unit effort (CPUE) across survey years. The southerly shift …

Matrilateral Bias Of Grandparental Investment In Grandchildren Persists Despite The Grandchildren’S Adverse Early Life Experiences, Samuli Helle, Antti O. Tanskanen, David A. Coall, Mirkka Danielsbacka

Research outputs 2022 to 2026

Evolutionary theory predicts a downward flow of investment from older to younger generations, representing individual efforts to maximize inclusive fitness. Maternal grandparents and maternal grandmothers (MGMs) in particular consistently show the highest levels of investment (e.g. time, care and resources) in their grandchildren. Grandparental investment overall may depend on social and environmental conditions that affect the development of children and modify the benefits and costs of investment. Currently, the responses of grandparents to adverse early life experiences (AELEs) in their grandchildren are assessed from a perspective of increased investment to meet increased need. Here, we formulate an alternative prediction that …

Modeling Digital Camera Monitoring Count Data With Intermittent Zeros For Short-Term Prediction, Eben Afrifa-Yamoah, Ute Mueller

Research outputs 2022 to 2026

Digital camera monitoring has revolutionised survey designs in many fields, as an important source of information. The extended sampling coverage offered by this monitoring scheme makes it preferable compared to other traditional methods of survey. However, data obtained from digital camera monitoring are often highly variable, and characterized by sparse periods of zero counts, interspersed with missing observations due to outages. In practice, missing data of relatively shorter duration are mostly observed and are often imputed using interpolation techniques, ignoring long-term trends leading to inherent estimation biases. In this study, we investigated time series forecasting methods that adequately handle intermittency …

Dual Contribution Of The Gut Microbiome To Immunotherapy Efficacy And Toxicity: Supportive Care Implications And Recommendations, Hannah R. Wardill, Raymond J. Chan, Alexandre Chan, Dorothy Keefe, Samuel P. Costello, Nicolas H. Hart

Research outputs 2022 to 2026

The efficacy of immune checkpoint inhibitors (immunotherapy) is increasingly recognized to be linked to the composition the gut microbiome. Given the high rates of resistance, interventions targeting the gut microbiome are now being investigated for its ability to improve the efficacy of immunotherapy. In light of recently published data demonstrating a strong correlation between the efficacy and toxicity of immunotherapy, there is a risk that efforts to enhance immunotherapy efficacy may be undermined by increases in immune-related adverse events (IrAEs) This is particularly important for microbial interventions aimed at increasing immunotherapy efficacy, with many microbes implicated in tumour response also …

Rethinking The Classification Of Games And Sports In Physical Education: A Response To Changes In Sport And Participation, Justen O'Connor, Laura Alfrey, Dawn Penney

Research outputs 2022 to 2026

Background Through changing the way games are represented, classification systems have increased possibilities for teaching game forms beyond structured adult and singular official versions of popular sports. At the time of inception, the four-game form approach to classification (target, net/wall, striking/fielding, and invasion games) enabled modified, small sided conditioned games to be adapted to suit individual attributes, whilst reinforcing a core set of tactical and technical elements for transfer. With global shifts in patterns of sport participation, it is timely to review this dominant classification frame and the role it plays within physical education (PE). Purpose This paper proposes changes …

Openness About Sexual Orientation And Exposure To Workplace Bullying, Helge Hoel, Duncan Lewis, Anna Einarsdottir, Guy Notelaers

Research outputs 2022 to 2026

Previous studies of workplace bullying have not investigated whether Lesbian, Gay and Bisexual (LGB) employees experience bullying in similar or different ways to their heterosexual counterparts. This study reports on how and to what extent sexuality or sexual orientation influences the experience of workplace bullying and whether openness about sexual orientation elevates risks and shapes exposure to bullying. Using a large and rigorously compiled sample of the British working population comprising 500 non-heterosexuals and 722 heterosexuals (N = 1,222) and applying latent Class Cluster Analysis, a similar behavioural pattern of bullying for LGB employees emerged as for heterosexuals, although LGB …

Changes To The Gut Microbiome In Young Children Showing Early Behavioral Signs Of Autism, Jacquelyn Jones, Stacey N. Reinke, Mahsa Mousavi-Derazmahalleh, Debra J. Palmer, Claus T. Christophersen

Research outputs 2022 to 2026

The human gut microbiome has increasingly been associated with autism spectrum disorder (ASD), which is a neurological developmental disorder, characterized by impairments to social interaction. The ability of the gut microbiota to signal across the gut-brain-microbiota axis with metabolites, including short-chain fatty acids, impacts brain health and has been identified to play a role in the gastrointestinal and developmental symptoms affecting autistic children. The fecal microbiome of older children with ASD has repeatedly shown particular shifts in the bacterial and fungal microbial community, which are significantly different from age-matched neurotypical controls, but it is still unclear whether these characteristic shifts …

Exploring Moderators Of The Effect Of High Vs. Low-To-Moderate Intensity Exercise On Cardiorespiratory Fitness During Breast Cancer Treatment – Analyses Of A Subsample From The Phys-Can Rct, Ann Christin Helgesen Bjørke, Laurien M. Buffart, Truls Raastad, Ingrid Demmelmaier, Andreas Stenling, Karin Nordin, Sveinung Berntsen

Research outputs 2022 to 2026

Introduction

The results from the physical training and cancer randomized controlled trial (Phys-Can RCT) indicate that high intensity (HI) strength and endurance training during (neo-)adjuvant cancer treatment is more beneficial for cardiorespiratory fitness (CRF, measured as peak oxygen uptake [VO₂peak]) than low-to-moderate intensity (LMI) exercise. Adherence to the exercise intervention and demographic or clinical characteristics of patients with breast cancer undergoing adjuvant treatment may moderate the exercise intervention effect on VO₂peak. In this study, the objective was to investigate whether baseline values of VO2peak, body mass index (BMI), time spent in moderate- to vigorous-intensity physical activity …

Finding Geodesics Joining Given Points, Lyle Noakes, Erchuan Zhang

Research outputs 2022 to 2026

Finding a geodesic joining two given points in a complete path-connected Riemannian manifold requires much more effort than determining a geodesic from initial data. This is because it is much harder to solve boundary value problems than initial value problems. Shooting methods attempt to solve boundary value problems by solving a sequence of initial value problems, and usually need a good initial guess to succeed. The present paper finds a geodesic γ: [0 , 1] → M on the Riemannian manifold M with γ(0) = x0 and γ(1) = x1 by dividing the interval [0,1] into several sub-intervals, preferably just …

Impacts Of Atmospheric Stilling And Climate Warming On Cyanobacterial Blooms: An Individual-Based Modelling Approach, Mohammad Hassan Ranjbar, David P. Hamilton, Amir Etemad-Shahidi, Fernanda Helfer

Research outputs 2022 to 2026

Harmful algal blooms of the freshwater cyanobacteria genus Microcystis are a global problem and are expected to intensify with climate change. In studies of climate change impacts on Microcystis blooms, atmospheric stilling has not been considered. Stilling is expected to occur in some regions of the world with climate warming, and it will affect lake stratification regimes. We tested if stilling could affect water column Microcystis distributions using a novel individual-based model (IBM). Using the IBM coupled to a three-dimensional hydrodynamic model, we assessed responses of colonial Microcystis biomass to wind speed decrease and air temperature increase projected under a …
