“It Felt Like A Sense Of Rape:” Women’S Experiences Of Strip Searching In Prison As Gendered, Misogynoir, And Colonial Genocidal Sexual Violence, Jessica Hutchison

Theses and Dissertations (Comprehensive)

Previously imprisoned women have long been sounding the alarm about the harms of strip searching and calling for it to be banned. However, it remains a routine prison practice and research into it is scant. Furthermore, Canada is incarcerating Indigenous women at genocidal levels and disproportionately imprisoning Black women. Therefore, my research explored the use of strip searching in federal prisons through anti-colonial and anti-racist feminist frameworks, specifically, abolition feminism.

My research was grounded in the ethic of relational accountability and centred reciprocity, respect, and responsibility in each phase. I gathered stories from 23 formerly incarcerated women from across Canada …

An Exploration Of The Link Between Vertebral Endplate Fracture, Velocity, And Health Of The Intervertebral Disc., John Mcmorran

Theses and Dissertations (Comprehensive)

The capacity for fractures to manifest in the growth cartilage of the adolescent human spine is well documented, but much of the knowledge available regarding such fractures remains retrospective and is largely composed of small case series made up of relatively few participants. In-vitro tissue testing has demonstrated that pressurization of the intervertebral disc’s nucleus pulposus significantly contributes to the generation of growth plate fractures. However, a comprehensive biomechanical investigation of the mechanical consequences for the intervertebral disc when exposed to ring apophyseal (growth plate) fractures at different velocities remains to be demonstrated.

The first two experiments of the present …

Action Strategies Of Young Adults During An Attentionally Demanding Collision Avoidance Task In Virtual Reality, Brooke J. Thompson

Theses and Dissertations (Comprehensive)

Walking and navigating through cluttered environments is a task that people do almost automatically while completing multiple cognitive and motor tasks simultaneously. Vision plays an essential role in adaptive locomotion as it allows individuals to make anticipatory actions (i.e., alter trajectory and/or gait speed) to successfully avoid oncoming collisions (Cinelli et al., 2008; Patla, 1997). To initiate a behaviour change at the appropriate time, humans rely on optical variables such as time-to-contact (TTC) (Cinelli & Patla, 2007). After determining when to initiate an avoidance behaviour, it is thought that humans maintain a protective zone (i.e., safety margin) by controlling the …

Examining Adjacent Disc Disease: A Novel In-Vitro Tissue Approach, Noah Chow, Noah Chow

Theses and Dissertations (Comprehensive)

When a patient experiences extreme degeneration of an intervertebral disc, a spinal fusion may be considered as a viable treatment plan. However, any implementation of hardware will change the biomechanics of the spine. This premise has led to the debate around adjacent disc disease (ADD) which is defined as the disc adjacent to a fused functional spine unit experiencing an accelerated rate of degeneration. There is a large controversy regarding ADD as a relevant pathology; however, it is largely unknown how spinal fusions effect the mechanical properties of the adjacent annulus fibrosus. Therefore, this thesis aims to examine the effect …

Is Task Conflict Truly Good For Everyone? Examining The Interaction Between Task Conflict And Gender On Individual Outcomes, Samantha Hancock

Theses and Dissertations (Comprehensive)

This dissertation examines perceptions of task conflict instigators. Task conflict is a core process that teams need to engage in to solve complex problems, however we know little about how the individual who instigates the task conflict is perceived, and what effects these perceptions have on important workplace outcomes like co-worker interaction intentions, promotion potential, and leadership potential. I propose that women who instigate task conflict may be perceived differently on the two fundamental dimensions of person perception: agency and communion. These perceptions, in turn, go on to influence important workplace outcomes that could provide additional insight into why there …

Collision Avoidance Strategies Of Middle-Aged Children And Young Adults In A Virtual Environment, Megan Hammill

Theses and Dissertations (Comprehensive)

The ability to perceive and react to visual information is critical for avoiding a collision with an approaching obstacle. The perception-action system undergoes a prolonged period of development and as a result, children make more last-minute locomotor adjustments than adults when avoiding stationary obstacles. The purpose of this thesis was to compare the avoidance behaviours of middle-aged children (10-12 years old) to young adults (YA) during a head-on collision course with an approaching virtual pedestrian (VP). Children (N=16, 10.8 0.75 years; 8 males) and YA (N=16, 22.94 2.08 years; 7 males) were immersed in a virtual environment using the HTC …

(Re)Mediating History In Canadian Auto/Biographic Long Poems Since 1970, Heather Olaveson

Theses and Dissertations (Comprehensive)

Responding to current topics of national debate around cultural appropriation, authenticity of voice and identity, historical commemoration, and foundational systems of social injustice, this dissertation takes as its launching point the question of how we are implicated in each other's histories. It examines the politics of rewriting history in Canadian auto/biographic long poems from 1970 to the present, reconsidering historiography as it intersects with life writing, gender, race, and the performance of voice. What narratives are reimagined about the lives of Canadian historical figures, how are such stories articulated, and who is permitted to perform the telling? As a whole, …

Experiences Of Quality Of Life Among Youth Experiencing Homelessness, Mental Health Problems, And Addictions, Wilsy Choudhary

Theses and Dissertations (Comprehensive)

Youth experiencing homelessness are often at a higher risk for developing concurrent mental health and addiction disorders. Existing interventions such as Housing First for Youth (H4FY) aim to provide youth experiencing homelessness with immediate access to safe, affordable housing as well as social inclusion and wellness supports. Furthermore, mental health interventions in the form of an integrated mental health and addictions (IMHA) service model have also been proposed to address the access barriers in place for youth experiencing homelessness, such as arbitrary exclusion criteria for substance use, long waiting periods and to further help them navigate the existing complex mental …

Nitrogen: Both A Potential Stimulator And Suppressor Of Cyanobacterial Blooms In Temperate Lakes, Catherine Goltz

Theses and Dissertations (Comprehensive)

Cyanobacterial blooms are complex phenomenon that are impacted and controlled by various factors such as lake depth, air temperature, wind, and nutrient loading. Nutrients such as phosphorus, nitrogen and iron all have very differing effects on cyanobacterial blooms. While phosphorus and iron are known to drive cyanobacterial biomass, nitrogen has been observed to have a direct impact on toxin synthesis. Nitrogen exists in the environment in many different forms such as atmospheric N₂, in inorganic forms such as nitrate and ammonium as well as in organic forms such as urea which can all affect cyanobacterial bloom development differently. …

"I'M Not Working, But I'M A Professional": Precarious Employment Pathways, Consequences, And Resistance Strategies Impacting The Health Of Racialized Immigrant Women, Elizabeth C. Watters

Theses and Dissertations (Comprehensive)

Precarious employment, which is characterized by low wages, insecurity, few entitlements, and a higher risk of ill health, is on the rise in Canada; however, precarious forms of employment are not equally distributed across society, but are borne disproportionately by some groups, including racialized immigrant women. To better understand the impact of precarious employment on the health of racialized immigrant women, I conducted a qualitative study consisting of semi-structured interviews (n=21) and two follow-up focus groups (n=11) with women in Southwestern Ontario. The women were recruited through a combination of convenience and snowball sampling and were compensated for their time …

Teammate Social Support For Female Athletes Recovering From Sports-Related Concussion, Brianna Iltshishin, Jennifer Robertson-Wilson, Michael Cinelli

Theses and Dissertations (Comprehensive)

Objective: Social support is a complex, multi-dimensional construct that is a vital coping mechanism for athletes experiencing sports-related concussion (SRC). Typically reported sources of social support include coaches, athletic therapist, and family/friends. This qualitative study, guided by a phenomenological orientation, aimed to understand previously concussed female athletes’ perceptions of the social support provided by their teammates. The study also explored how social support, or lack of social support, affected athletes as they navigated their concussion recovery.

Methods: Five participants were recruited through purposive and snowball sampling. Data collection consisted of background questionnaires and one semi-structured one-on-one interview. Interviews were transcribed …

Exploring The Membrane Protein And Peptide Interactions Of Mitochondrial And Bacterial Lipid Systems, George Saudan

Theses and Dissertations (Comprehensive)

This study aims to expand the understanding of interactions between membrane lipids and proteins, and relate it to their biological functions in two experimental systems. The first system focuses on the interaction and conformation of a membrane protein Uncoupling Protein 4 (UCP4) in mitochondrial inner membrane lipids, in the absence and presence of cardiolipin; a lipid specific to mitochondrial inner membranes. The second system considers the interaction and conformation of a cell penetrating peptide, Penetratin, which can interact with both mammalian and bacterial cells. A N- and C-termini protected form of this 16-meric peptide (Pen2) was used to explore its …

A Machine Learning Approach To Classify Open Water And Ice Cover On Slave River Delta, Ida Moalemi

Theses and Dissertations (Comprehensive)

Seasonal temperature trend and ice phenology in Great Slave lake (GSL), are strongly influenced by warmer inflow from Slave river. The Slave river flows to GSL through Slave river delta (SRD), bringing a rise in temperature that triggers the ice break-up process of the lake. Slave river discharge is subject to multiple stressors including climate warming and upstream water activities, which in turn, directly affects the GSL break-up process. Consequently, monitoring the break-up process at SRD, where the river connects to the lake, serves as an indicator to better understand the cascading effects on GSL ice break-up. This research aims …

A Close Look At The Connections Between Mental-State Talk, Theory Of Mind, And Source Monitoring During Parent-Child Reminiscing Of Emotional Events, Mallory Earnshaw

Theses and Dissertations (Comprehensive)

Autobiographical memories play a critical role in shaping personal identity, regulating emotions, and guiding future behaviour. Reminiscing about these memories can be particularly beneficial for coping with negative experiences. This study investigated the connections between mental-state talk, theory of mind, and source monitoring in parent-child reminiscing, and how it can be influenced by remembering enjoyable versus frustrating events. This study involved children ages 3-8 (N = 50) and consisted of two sessions. In the first session, the child reminisced with their parent about an enjoyable and frustrating event and completed two source-monitoring tasks. In the second session, the child …

Phosphorus Release And Recovery From Simulated Ferric Wastewater Sludge, Aseel Alnimer

Theses and Dissertations (Comprehensive)

Phosphorus (P) is a fundamental element necessary for all life forms and a key component in the fertilizer industry. Meanwhile, the excessive load of P to water bodies due to human activities has the potential to promote eutrophication. Wastewater treatment plants remove P either biologically or chemically and produce P rich sludge which could be a potential renewable source for P. At present, commercial technologies exist for P recovery from biological wastewater sludge. However, P recovery from chemical sludge particularly iron(III)-phosphate (Fe-P) sludge generated in chemical P removal plants that use iron(III) salts remains a challenge.

This study explored, in …

Ethical Dilemmas And Moral Distress In Companion Animal Veterinary Medicine: Mental Health Implications, Bronwyn Dickson

Theses and Dissertations (Comprehensive)

Mental health concerns are a significant problem in the veterinary community, and studies suggest that veterinarians working in Western countries are at higher risk of suicide compared to the general population and other healthcare professionals (Bartram et al., 2009; Bartram & Baldwin, 2010; Platt et al., 2012). Additionally, veterinary medicine is an occupation inundated with complex ethical and moral dilemmas. However, current studies are limited in their ability to contextualize the risk and contributing factors fully; therefore, they offer limited insight into effective preventative and support strategies. Using Interpretive Phenomenological Analysis (IPA), eight companion animal veterinarians were interviewed about their …

Borsuk–Ulam Type Theorems For G-Spaces With Applications To Tucker Type Lemmas, Oleg R. Musin, Alexey Yu. Volovikov

School of Mathematical & Statistical Sciences Faculty Publications

In this paper we consider several generalizations of the Borsuk–Ulam theorem for G-spaces and apply these results to Tucker type lemmas for G-simplicial complexes and PL-manifolds.

Equity In Focus : Investigating Gender Disparities In Glioblastoma Via Propensity Score Matching, Solomon Eshun

School of Mathematical & Statistical Sciences Faculty Publications

Gender disparities in health outcomes have garnered significant attention, prompting investigations into their underlying causes. Glioblastoma (GBM), a devastating and highly aggressive form of brain tumor, serves as a case for such inquiries. Despite the mounting evidence on gender disparities in GBM outcomes, investigations specific at the molecular level remain scarce and often limited by confounding biases in observational studies. In this study, I aimed to investigate the gender-related differences in GBM outcomes using propensity score matching (PSM) to control for potential confounding variables. The data used was accessed from the Cancer Genome Atlas (TCGA), encompassing factors such as gender, …

Deriving Spatially Explicit Direct And Indirect Interaction Networks From Animal Movement Data, Anni Yang, Mark Q. Wilber, Kezia R. Manlove, Ryan S. Miller, Raoul Boughton, James Beasley, Joseph Northrup, Kurt C. Vercauteren, George Wittemyer, Kim Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Quantifying spatiotemporally explicit interactions within animal populations facilitates the understanding of social structure and its relationship with ecological processes. Data from animal tracking technologies (Global Positioning Systems [“GPS”]) can circumvent longstanding challenges in the estimation of spatiotemporally explicit interactions, but the discrete nature and coarse temporal resolution of data mean that ephemeral interactions that occur between consecutive GPS locations go undetected. Here, we developed a method to quantify individual and spatial patterns of interaction using continuous-time movement models (CTMMs) fit to GPS tracking data. We first applied CTMMs to infer the full movement trajectories at an arbitrarily fine temporal scale …

High Winds And Melting Sea Ice Trigger Landward Movement In A Polar Bear Population Of Concern, Annie Kellner, Todd C. Atwood, David C. Douglas, Stewart W. Breck, Colorado State University - Fort Collins

United States Department of Agriculture Wildlife Services: Staff Publications

Some animal species are responding to climate change by altering the timing of events like mating and migration. Such behavioral plasticity can be adaptive, but it is not always. Polar bears (Ursus maritimus) from the southern Beaufort Sea subpopulation have mostly remained on ice year-round, but as the climate warms and summer sea ice declines, a growing proportion of the subpopulation is summering ashore. The triggers of this novel behavior are not well understood. Our study uses a parametric time-to-event model to test whether biological and/or time-varying environmental variables thought to influence polar bear movement and habitat selection …

Evaluation Of The Effect Of Hydrated Lime On The Scavenging Of Feral Swine (Sus Scrofa) Carcasses And Implications For Managing Carcass-Based Transmission Of African Swine Fever Virus, Courtney F. Bowden, James Grinolds, Gregory Franckowiak, Loma Mccallister, Joe M. Halseth, Matthew Cleland, Travis Guerrant, Michael J. Bodenchuk, Robert Miknis, Michael C. Marlow, Vienna R. Brown

United States Department of Agriculture Wildlife Services: Staff Publications

African swine fever (ASF) is a devastating hemorrhagic disease marked by extensive morbidity and mortality in infected swine. The recent global movement of African swine fever virus (ASFV) in domestic and wild swine (Sus scrofa) populations has initiated preparedness and response planning activities within many ASF-free countries. Within the US, feral swine are of utmost concern because they are susceptible to infection, are wide-spread, and are known to interact with domestic swine populations. African swine fever virus is particularly hardy and can remain viable in contaminated carcasses for weeks to months; therefore, carcass-based transmission plays an important role in the …

Disease Progression And Serological Assay Performance In Heritage Breed Pigs Following Brucella Suis Experimental Challenge As A Model For Naturally Infected Feral Swine, Vienna R. Brown, Ryan S. Miller, Courtney F. Bowden, Timothy J. Smyser, Nicholas A. Ledesma, Aim E. Hartwig, Paul Gordy, Aaron M. Anderson, Stephanie M. Porter, Kate Alexander, Zane Gouker, Tom Gidlewski, Richard A. Bowen, Angela M. Bosco-Lauth

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive feral swine (Sus scrofa) are one of the most important wildlife species for disease surveillance in the United States, serving as a reservoir for various diseases of concern for the health of humans and domestic animals. Brucella suis, the causative agent of swine brucellosis, is one such pathogen carried and transmitted by feral swine. Serology assays are the preferred field diagnostic for B. suis infection, as whole blood can be readily collected and antibodies are highly stable. However, serological assays frequently have lower sensitivity and specificity, and few studies have validated serological assays for B. suis in feral swine. …

Validation Of A Nutria (Myocastor Coypus) Environmental Dna Assay Highlights Considerations For Sampling Methodology, Anna M. Mangan, John A. Kronenberger, Ian H. Plummer

United States Department of Agriculture Wildlife Services: Staff Publications

Nutria (Myocastor coypus) is a semiaquatic rodent species that is invasive across multiple regions within the United States. Here, we evaluated a qPCR assay previously described for use in Japan for application across invasive populations in the United States. We also compared two environmental DNA sampling methodologies for this assay: field filtration of large volumes of water passed through filters versus direct sampling of small volumes of water. We validated assay specificity, generality, and sensitivity, compared assay performance between two independent laboratories, and successfully tested the assay in situ on a known wild population. The filtration method required …

Perturbations Highlight Importance Of Social History In Parakeet Rank Dynamics, Annemarie Van Der Marel, Xavier Francis, Claire L. O'Connell, Cesar O. Estien, Chelsea Carminito, Virginia Darby Moore, Nickolas Lormand, Bryan M. Kluever, Elizabeth A. Hobson

United States Department of Agriculture Wildlife Services: Staff Publications

Dominance hierarchies can provide many benefits to individuals, such as access to resources or mates, depending on their ranks. In some species, rank can emerge as a product of a group’s history of social interactions. However, it can be difficult to determine whether social history is critical to rank in observation-based studies. Here, we investigated rank dynamics in three captive groups of monk parakeets (Myiopsitta monachus). We used experimental social perturbations to test whether social history shapes rank emergence in these groups. Using targeted removals and reintroductions, we tested whether differently ranked individuals could re-take their ranks in hierarchies after …

Integrating The Theory Of Planned Behavior And Bonding Social Capital To Examine Chinese Women’S Tampon Use Intentions, Yin Yang, Young Kim

College of Communication Faculty Research and Publications

This study integrates the theory of planned behavior with a structural approach to examining social capital to investigate how bonding social capital affected Chinese women’s tampon use intentions. Bonding social capital was operationalized as network closure, which included two main dimensions: density and hierarchy. Results from an online survey (N = 766) showed that network density was positively associated with attitudes toward, social norms about, and perceived behavior control around tampon usage, while network hierarchy negatively predicted attitudes only. Moreover, the indirect effects of network density on tampon use intentions were mediated by descriptive norms and perceived behavior control. …

Whose Public Virtue? Exploring Freedom Of Information Efficacy And Support, A.Jay Wagner

College of Communication Faculty Research and Publications

Little is known about public perceptions of how FOI laws influence government operations or impact citizens’ daily lives. A large representative sample of U.S. adults was surveyed for support of FOI laws and perceptions of FOI efficacy. Findings showed advanced education and higher perceptions of general government efficacy to be strongly significant in predicting both support for FOI and greater FOI efficacy. Males and liberal respondents also demonstrated significance in predicting support for FOI and higher FOI efficacy, while Black race was a significant negative predictor in support for FOI and whether FOI improved government operations and accountability.

Families with children with developmental disabilities (DDs) experience effects on family functioning and will often turn to physical activity (e.g., dance) to mitigate these effects. This research examines the lived experiences of families with children with DDs participating in recreational dance programs to understand the myriad of effects on all participants: children with DDs, families, and dance instructors.

Methods

In order to fully understand the lived experiences of participants, phenomenology was used as the theoretical orientation to guide this research. Each case (5 cases, N=19) consisted of a primary parent, a child with a developmental disability, sibling(s) (if applicable), …

Still, We Thrive: Understanding How Gay, Bisexual, Transgender, And Other Men Who Have Sex With Men (Gbtmsm) Experience Structural Barriers & Facilitators To Wellness, Lucas Gergyek

Theses and Dissertations (Comprehensive)

Historically and concurrently, structural violence has been a significant force influencing the sexual health and broader health of gay, bisexual, transgender and other men who have sex with men (GBTMSM). Yet to date, the majority of projects exploring the health inequities facing GBTMSM have focused on intrapsychic and behavioural factors as most related to poor health outcomes. As well, these studies are sometimes deficits focused, and fail to evaluate how GBTMSM continue to thrive, and maintain positive health. As a result, the ways in which systems and policies underlie and perpetuate health inequities facing GBTMSM have been somewhat obscured. Connectedly, …

Utilizing Ground-Penetrating Radar To Estimate The Spatial Distribution Of Snow Depth Over Lake Ice In Canada’S Sub-Arctic, Alicia Pouw

Theses and Dissertations (Comprehensive)

With the expected rise in air temperature, it becomes important to understand how snow will respond in different climate scenarios. The presence of snow over lake ice largely influences the ice thickness, and as Canada’s Arctic and sub-arctic regions are experiencing warming at twice the global rate, concerns rise as changes in the snowpack will significantly impact northern communities that rely on lake ice as a means of transportation, source for drinking water, and feeding their families. The distribution of snow depth is highly sensitive to changes in climate over time, as such a slight increase in air temperature or …

I Am Queer And Asian: The Crossroad Of Race And Lgbtqia+ Identity Among Queer Asian Canadian Youth And The Impacts Of The Covid-19 Pandemic, Kenny Chee

Theses and Dissertations (Comprehensive)

LGBTQIA+ Asian youth face unique challenges due to their intersecting identities. Utilizing Asian Critical Race Theory and the Integration Model of Stress and Trauma in LGBTQIA+ Asians, LGBTQIA+ Asian youth are likely to experience detrimental mental health outcomes due to the stigmatization within their Asian culture and racial discrimination from the LGBTQIA+ communities. Moreover, the COVID-19 pandemic exacerbated existing challenges because of the closure of community spaces and increased hate crimes against Asians. Nonetheless, research on the intersectional experiences of LGBTQIA+ Asians in Canada, especially in the context of the COVID-19 pandemic is sparse. Thus, to address this gap, I …
