The Relationship Between Age, Sport, And Years Coaching On Knowledge, Confidence, Preparedness, And Intention To Intervene With Youth Athletes Experiencing Mental Health Challenges, Allyson P. Looby

College of Graduate Studies: Theses & Dissertations

Introduction: Mental disorders can affect all ages and populations, but there is an increasingly high prevalence in the pediatric population. It is estimated that 1 in 5 youth between the ages of 9-17 experiences some degree of impairment from a diagnosable mental health disorder (Merikangas et al., 2010). Youth are often not equipped to seek professional support; making parents, teachers, and coaches key to detection and referral to professional help (Ng et al., 2021). The environment youth sports creates gives coaches the opportunity to have a greater impact on youth mental health (Das et al., 2016). Purpose: Determine if age, …

"Having It Both Ways: Containing The Champions Of Feminism In Female-Led Origin And Solo Superhero Films", Jessica Taylor, Laura Glitsos

Research outputs 2014 to 2021

In this article, we consider the emerging trend of solo, female-led superhero films, and their repeated location in aesthetically distinct pasts or “closed moments.” This pastness, we contend, serves to distinguish the concerns of the protagonists, which are often read as feminist, as redundant for the contemporary audience. This framing is in keeping with a postfeminist cultural context, wherein feminist values and successes are celebrated, while simultaneously declared irrelevant.

We examine the historical or closed settings in Wonder Woman (2017), Wonder Woman 1984 (2020), Captain Marvel (2019) and Black Widow (2021), and consider how this collective investment in the past …

Observer-Based Model Predictive Control With Continuous Control Set For Single-Phase Rectifiers, Milad Dehghanzadeh, Rui Bo, Kamal Al-Haddad

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a model predictive controller (MPC) is designed for a single-phase rectifier. The proposed MPC works with a continuous control set (CCS) that addresses variable switching issues in finite control set (FCS) MPCs. The observe-ability of the rectifier enables the design of a full-state observer to measure only output voltage in which the AC current of the rectifier is estimated. Both the proposed controller and observer are assessed with simulation studies and the results show the acceptable performance of the observer and CCS-MPC as well as good disturbance rejection in load and network parameter variations.

Transformer Leakage Inductance Design Methodology, Angshuman Sharma, Jonathan W. Kimball

Electrical and Computer Engineering Faculty Research & Creative Works

The leakage inductance exhibited by a transformer depends on its winding geometry, which generally involves the selection of several key design parameters in addition to the winding structure and the interleaving configuration. With few resources explaining the effects of these design choices on the observed leakage inductance, numerous trial-and-error iterations become necessary to realize the desired leakage inductance. This paper explores more than a hundred winding geometries feasible in a 2- winding transformer comprising the same magnetic core, number of turns, and wire gauge, and finds the leakage inductance for each unique design using 2-D finite element method (FEM) simulations …

Solving Electromagnetic Inverse Scattering Problems In Inhomogeneous Media By Deep Convolutional Encoder-Decoder Structure, Huan Huan Zhang, He Ming Yao, Lijun Jiang, Michael Ng

Electrical and Computer Engineering Faculty Research & Creative Works

This communication proposes a novel deep learning (DL) approach to solve electromagnetic inverse scattering (EMIS) problems in inhomogeneous media. The conventional approaches for solving inhomogeneous EMIS problems generally have to consider inhomogeneous Green’s functions or conduct approximation operations to media, which inevitably introduces various challenges, including complex mathematical derivation, high computation cost, unavoidable nonlinearity, and even strong ill-posedness. To avoid these challenges, we propose a DL approach based on the complex-valued deep convolutional neural networks (DConvNets), which comprise the deep convolutional encoder–decoder (DCED) structure. Its training data are collected based on the simple synthetic dataset. While the scattered fields received …

Hydrogen Deuterium Exchange And Other Mass Spectrometry-Based Approaches For Epitope Mapping, Prashant N Jethva, Michael L Gross

2020-Current year OA Pubs

Antigen-antibody interactions are a fundamental subset of protein-protein interactions responsible for the "survival of the fittest". Determining the interacting interface of the antigen, called an epitope, and that on the antibody, called a paratope, is crucial to antibody development. Because each antigen presents multiple epitopes (unique footprints), sophisticated approaches are required to determine the target region for a given antibody. Although X-ray crystallography, Cryo-EM, and nuclear magnetic resonance can provide atomic details of an epitope, they are often laborious, poor in throughput, and insensitive. Mass spectrometry-based approaches offer rapid turnaround, intermediate structural resolution, and virtually no size limit for the …

Treg-Specific Deletion Of The Phosphatase Shp-1 Impairs Control Of Inflammation In Vivo, Qinlei Gu, Kenneth S Tung, Ulrike M Lorenz

2020-Current year OA Pubs

INTRODUCTION: To achieve a healthy and functional immune system, a delicate balance exists between the activation of conventional T cells (Tcon cells) and the suppression by regulatory T cells (Treg). The tyrosine phosphatase SHP-1, a negative regulator of TCR signaling, shapes this 'activation-suppression' balance by modulating Tcon cell resistance to Treg-mediated suppression. Treg cells also express SHP-1, but its role in influencing Treg function is still not fully understood.

METHODS: We generated a Treg-specific SHP-1 deletion model,

RESULTS: We show that SHP-1 modulates Treg suppressive function at different levels. First, at the intracellular signaling level in Treg cells, SHP-1 attenuates …

Nursing Students Doing Gender: Implications For Higher Education And The Nursing Profession, Lesley J. Andrew, Ken Robinson, Julie Dare, Leesa N. Costello

Research outputs 2022 to 2026

The average age of women nursing students in Australia is rising. With this comes the likelihood that more now begin university with family responsibilities, and with their lives structured by the roles of mother and partner. Women with more traditionally gendered ideas of these roles, such as nurturing others and self-sacrifice, are known to be attracted to nursing as a profession; once at university, however, these students can be vulnerable to gender role stress from the competing demands of study. A qualitative research design, guided by Gadamer's hermeneutic philosophy, explored the gendered behaviours and experiences of 22 women nursing students, …
