Body. Freedom. Choice: Creating Artwork In Post-Roe America, Erin Sedra

Graduate Theses/Dissertations

I knew from a young age that I never wanted children. Whenever I expressed my disinterest in motherhood, I was often met with bewilderment, disapproval, and hostility. The church I was raised in taught me that my value and worth as a woman directly correlated with the power of my birthing hips. This fundamentalist upbringing has significantly shaped my relationship with my femininity, my body, and my artwork. When I feel powerless, turning to my art gives me a sense of control and self-expression. This body of work began as a reaction to the overturning of Roe v. Wade and …

We assessed the predictive performance and variability at the sewershed level and compared the effects of adding or replacing wastewater data to case and death reports. …

"The Most Important Thing In Ipv Right Now": The Intersection Of Intimate Partner Violence And Brain Injury, Halina (Lin) Haag

Theses and Dissertations (Comprehensive)

The intersection of intimate partner violence (IPV) and brain injury (BI) has been almost entirely overlooked in research, practice, and policy, despite the known risks associated with the two conditions. Individually, IPV and BI are associated with elevated rates of unemployment, poverty, and homelessness, as well as increased mental health challenges. These social determinants of health, employment status, and income impact women’s wellbeing through access to safe accommodations, food security, and (dis)ability supports. These determinants are also related to an increased likelihood of experiencing addictions, mental health challenges, and physical danger, potentially leaving women vulnerable to ongoing violence. This qualitative …

Overcoming The Unseen: Understanding Diverse Canadian Workers’ Well-Being During The Beginning Of The Coronavirus Pandemic, Tyler M. Pacheco

Theses and Dissertations (Comprehensive)

Canadian workers were severely affected by the onset of the coronavirus (COVID-19) pandemic. The rapid spread of the pathogen across Canada resulted in several work-related consequences (e.g., temporary/indefinite layoffs and business closures, mandatory working-from-home) that could have impacted workers’ well-being during this turbulent period. Research available at the start of this dissertation process, and even more recently published studies, primarily explored general trends in workers’ negative well-being during COVID-19, not examining the distinct realities that diverse workers, including more marginalized ones, may have experienced. Across three manuscripts, several theories from diverse disciplines (positive, developmental, community, and industrial-organizational psychology, public health) …

Body-Map Storytelling: A Qualitative Exploration Of The Lived Experiences Of Hospital Care Amongst Street Involved Youth, Chelsey Fedchenko

Theses and Dissertations (Comprehensive)

This social work study explores the experiences of hospital care amongst street-involved (SI) youth.

Yet, inadequate health care support for SI youth remains a critical problem in Canada. While hospital care amongst adult homeless populations has been well studied interdisciplinary, there is a scarcity of research investigating the hospital care experiences amongst SI youth. The aim of this qualitative, arts-based study was to explore how street-life contributes to hospitalization, how SI youth …

On The Area-Averaged Effective Sound Absorption Coefficient Of Porous Materials Excited By A Monopole, Franck Sgard, Noureddine Atalla, Olivier Robin, Alain Berry

Études primaires

The area-averaged effective sound absorption coefficient (SAC) of a rigid-backed homogeneous porous material subjected to a monopole excitation is calculated as the absorbed-to-incident sound power ratio. Using Allard's model to describe the sound propagation above the porous material, an analytical model for this power-based SAC is proposed and proves to give a good approximation of the sound absorption performance under monopole excitation of sufficiently large areas of material. The impact of factors on the power-based SAC, such as monopole height, material radial dimension used to calculate the sound powers, and material properties is discussed. The power-based SAC frequency-dependent behavior is …

Measurement Of The Local Static Mechanical Pressure Of Earplugs, Luiz G.C. Melo, Ahmed S. Dalaq, Franck Sgard, Olivier Doutres, Laurianne Legroux, Eric Wagnac

Études primaires

Earplugs are used in various critical industrial sectors, such as construction, aviation, military and defense, transportation, and healthcare. However, they present inherent drawbacks, notably discomfort that can lead to inconsistent and incorrect use, thereby leaving a significant proportion of workers vulnerable to irreversible hearing damage, ranging from tinnitus to deafness. This discomfort is closely linked to a physical parameter known as static mechanical pressure (SMP), representing the pressure exerted by earplugs on the earcanal walls. Determining the SMP is crucial for developing earplugs that prioritize comfort. However, experimental studies in this area are scarce and there is no experimental set-up …

An Impedance Tube Technique For Estimating The Insertion Loss Of Earplugs, K. Carillo, O. Doutres, F. Sgard

Études primaires

This paper proposes a quick and straightforward technique for estimating the insertion loss (IL) of earplugs measured on an acoustical test fixture (ATF) using a commercial impedance tube. In this method, the earplug's acoustic properties (i.e., its transmission loss and the reflection coefficient of its medial surface) are determined from its transfer matrix measured using the three-microphones impedance tube method modified here for the current application. The IL is then estimated using a one-dimensional analytical model of open and occluded earcanals based on the wavefield decomposition theory. The method is evaluated numerically and experimentally from 50 Hz to 6.5 kHz. …

Comparative Evaluation Of Different Spinal Stability Metrics, Amir Hossein Eskandari, Farshid Ghezelbash, Aboulfazl Shirazi-Adl, Christian Larivière

Études primaires

Direct in vivo measurements of spinal stability are not possible, leaving computational estimations (such as dynamic time series and structural analyses) as the feasible option. However, differences between different stability assessment approaches and metrics remain unclear. To explore this, we asked 32 participants to perform 35 cycles of repetitive lifts with and without load (4/2.6 kg for males/females). EMG signals and 3D kinematics were collected via 12 surface electrodes and 17 inertial sensors, and three dynamical stability measures were computed: short and long temporal and conventional maximum Lyapunov exponents (LyE) and maximum Floquet multipliers (FM). A dynamic subject-specific EMG-assisted musculoskeletal …
