Approaches To Preventing Applicants From Faking Personality Assessments: Construct Contamination Under Faking Conditions, Peter A. Fisher

Theses and Dissertations (Comprehensive)

Personality testing is a popular and useful predictor of future job performance in personnel selection. Personality assessment faking behaviour, however, threatens the usefulness of personality in personnel selection by reducing the validity of assessment results and creating distrust in the assessment results. Recent research exploring a new, computer-mediated assessment response format, the Rapid Response Measure (RRM; Meade et al., 2020), has the potential to dramatically change the way personality assessment is conducted in high-stakes, personnel selection. An initial investigation of the RRM suggests that it may significantly reduce personality assessment faking behaviours. The means by which the RRM is proposed …

Exploring The Relationship Between Drought And Population Change On The North American Great Plains, 1970-2010, George Heath

Theses and Dissertations (Comprehensive)

Through the second half of the 20th century, the North American Great Plains saw widespread rural out-migration, a continuation of trends that began with the Dust Bowl crisis during the Great Depression of the 1930s. As part of a wider academic focus on the roles climate and environmental changes have on migration, this research project sought to understand the relationship between drought conditions and rural population decline on the Great Plains. In this explorative research, census population data for Canada and the US from 1970-2010 were analyzed along with temperature, precipitation, and Palmer Drought Severity Index data for the same …

The Electrophysiological Correlates Of Text Integration And Direct Vs. Indirect Articles: A Centralized And Lateralized Examination, Deanna C. Hall

Theses and Dissertations (Comprehensive)

As we read, we develop mental models of the discourse content called situation models. Situation models are integral to how we keep track of information, and to do so in an ongoing event incoming information needs to be integrated into the model or discarded. The type of information being presented, and its relation to prior data, impacts how that new information is processed. The current research examined discourse passages containing concepts that were either previously mentioned (match), mentioned with a general term (general category), unmentioned in lieu of another concept (mismatch), or completely unmentioned previously (indeterminate), and examined how these …

Trans-Forming Resilience Research: A Critical Interpretive Synthesis Of Resilience Research With Transgender And Gender Diverse Populations, Morgan Brooks

Theses and Dissertations (Comprehensive)

Historically, much of the research pertaining to transgender and gender diverse (trans) health and wellbeing has been conducted in ways that are reductive, pathologizing and exploitative. Trans activists and scholars express concerns about how such research contributes to pervasive negative perceptions, stigma, and cisgenderism, reinforcing stereotypical, binary ideas of trans people as both damaged and dangerous, vulnerable and heroic. Ongoing negative media attention and harmful policy decisions rooted in these views demonstrate the importance of offering alternatives to these reductive, deficit-based narratives associated with trans people. In response, strengths-based research oriented around the construct of resilience is increasing; yet approached …

Bee Cities And More-Than-Human Communities: Protecting Pollinators In The Anthropocene, Jennifer Marshman

Theses and Dissertations (Comprehensive)

Grounded in political ecology and the ecological humanities, the aim of this research is to examine the Bee City movement as a conservation engagement strategy at the municipal level. While pollinator research occurs from a variety of perspectives – biology, entomology, phylogeny, ecology, and agricultural sciences - social engagement strategies and the human dimensions of pollinator conservation have yet to be widely investigated. This research questions if these strategies put in place, and contribute to, important political and socio-ecological mechanisms in the local context. Through a collective case study methodology, this research points to the Bee City movement as a …

Changes In Plant Community Composition, Structure, And Function In Response To Permafrost Thaw, Katherine Standen

Theses and Dissertations (Comprehensive)

Air temperature is increasing at three or more times the global average in high latitudes, causing widespread permafrost thaw across the boreal biome. Since the boreal biome stores 30-40% of global terrestrial carbon (C), of which about 30-45% is found in permafrost soils, this temperature increase could cause a large efflux of C to the atmosphere. Climate warming and permafrost thaw are also expected to alter plant community composition and productivity and, given the link between plant functional traits and ecosystem C fluxes, may alter overall ecosystem function. Across the boreal biome of western Canada, we know surprisingly little about …

Discovery Of Inhibitors Of Peptidoglycan O-Acetyltransferase B (Patb) From Neisseria Gonorrhoeae, A New Potential Antibacterial Target, Stefen Stangherlin

Theses and Dissertations (Comprehensive)

Experts project that by 2050, 10 million lives will be lost annually as a result of antimicrobial resistant infections, surpassing all current leading causes of death, and costing the global economy $100 trillion USD on healthcare efforts. To promote research and development of novel antibiotics, the World Health Organization and Centers for Disease Control and Prevention released a list of priority pathogens regarded as serious or urgent threats of antimicrobial resistance. Many pathogenic bacteria, including several priority pathogens, produce O-acetylated peptidoglycan to establish infection and avoid host immune responses. Consequently, the enzymes responsible for producing O-acetylated peptidoglycan in Gram-negative pathogenic …

Impacts Of Changing Permafrost Conditions On Vegetation Productivity In The Northern Boreal Forest, Emily Ogden

Theses and Dissertations (Comprehensive)

Vegetation productivity across the boreal forest has increased over the past several decades. However, at a regional scale there is large variation from increased (greening) to decreased (browning) productivity and large areas with no measured change. Some of this variation can be explained by disturbances, such as wildfire, or by increased climate variability. In northern regions underlain by permafrost, the interactions between climate, disturbance, and vegetation productivity may be more complex. For my thesis, I used a time-series of ground thermal data from permafrost monitoring sites established by the Geological Survey of Canada along a latitudinal transect of the Northwest …

Abstract Immigrant spouses face culture shock in the host countries because they are disconnected from their social fabric and, at the same time, must adhere to the host countries' lifestyles. One of the immigrants' spouses' challenges is the marital conflicts that arise because of changing gender norms in the host countries and the absence of family support to solve their conflicts. The purpose of this study is to examine changing gender norms and traditional meditation's impact on marriage among Ethiopian immigrants living in Kitchener, Waterloo and Guelph. The study asks overarching research question: what is the impact of changing gender …

Influence Of Dissolved Organic Matter On Phosphate Interactions With Hydrous Ferric Oxides, Alaa Hasan Alsherbi

Theses and Dissertations (Comprehensive)

Phosphorus, iron oxides, and dissolved organic matter (DOM) are components present in all aquatic systems. Excess amounts of phosphorus in aquatic systems have the potential for toxic effects, in particular, contributing to eutrophication. Most of the previous studies performed looked at the surface complexation of inorganic phosphate anions (P) to mineral surfaces such as hydrous ferric oxide (HFO). However, the role of DOM on the interactions between HFO and P is unknown. This study investigates the influence of DOM on the surface complexation of P onto HFO surfaces. Moreover, this study looks at the possibility of cation bridging formation (Ca …

The overall theme of this research was to synthesize and study the structure-property relationships of novel polycyclic aromatic compounds capable of self-assembling to form liquid crystalline, and microporous structures, as well as molecules capable of molecular recognition. The unifying theme that connects this research is the utilization of the Yamamoto coupling reaction to access the desired polycyclic aromatic hydrocarbon targets. More specifically, the scope of the Yamamoto coupling reaction was explored for the synthesis of electron-deficient triphenylene derivatives that are otherwise difficult to prepare. The molecules prepared via the Yamamoto coupling reaction are expected to be further utilized as intermediates …

Enhancing Zero-Shot And Few-Shot Text Classification Using Pre-Trained Language Models, Yanan Chen

Theses and Dissertations (Comprehensive)

In recent years, the community of natural language processing (NLP) has seen amazing progress in the development of pre-trained language models (PLMs). The novel paradigm of PLMs does not require labeled data, allowing us to experiment with increased training scale through employing freely available colossal online self-training corpus to push the limits. Language models (LMs), such as GPT, BERT and T5, have achieved high performance on a wide range of NLP tasks. Meanwhile, research on zero-shot and few-shot text classification has received increasing attention. As labelling can be costly and time-consuming, how to perform data augmentation (DA) and enhance the …

Lyme disease is the most common vector-borne zoonosis in North America and over the past decade, reported cases of the disease have been rapidly increasing in many regions throughout Canada. The relative novelty of this public health threat presents nature-based tourism and recreation organizations with a range of policy and management challenges. Currently, there is a limited understanding of public perceptions and behaviours associated with tick and Lyme disease risk, especially within a Canadian parks and protected areas visitation and visitor experience context. To address this practical and scholarly knowledge gap, this study utilized in-situ surveys to explore visitor perceptions, …

Young Adult And Adolescent Balance Control Strategies During A Dual-Task Stone-Stepping Paradigm, Emily Ford

Theses and Dissertations (Comprehensive)

Stone-stepping demands greater attention and visuomotor integration, as it requires precise foot placement. The amount of attention required during locomotion is typically assessed with a secondary task, by analyzing the dual-task cost. Adolescents are suggested to have a greater dual-task cost than young adults and demonstrate balance control impairments while dual-tasking walking. The purpose of the current study was to explore the balance control differences between adolescents and young adults during a stone-stepping paradigm. We hypothesized that adolescents would experience greater balance control deficits while performing the secondary task compared to the young adults, especially while on the uneven terrain. …

Inducing Kindness To Cope With Social Stress: Comparing Self-Compassion With Cognitive Reappraisal, Cortney Burnham

Theses and Dissertations (Comprehensive)

Self-compassion involves being accepting and caring toward oneself when dealing with failure and hardships. Inducing self-compassion has been shown to be helpful, particularly for individuals with high levels of social anxiety. However, few studies have compared a self- compassion intervention to another adaptive strategy. The primary aim of the present study was to examine the impact of a self-compassion induction for social stress compared to another beneficial strategy. Three studies were conducted to compare self-compassion and cognitive reappraisal as strategies for coping with past stressful social situations and current social stress. In Study 1, participants (N = 276) were …

Loose Coupling, Burden Shuffling, And Pervasive Penality: The Role Of Bylaw Enforcement In Managing Homelessness, Natasha Martino

Theses and Dissertations (Comprehensive)

In Canada, over 235,000 people experience homelessness per year. The COVID-19 pandemic has increased the visibility of homelessness and the use of homeless encampments across Ontario. As visibility has increased, so too have community members’ expectations to manage homelessness or find a solution to minimize the visibility of homelessness. While there has been some scholarship about the police management of homelessness, far less is known about the role of bylaw enforcement. Yet, bylaw officers play a critical role in responding to homelessness due to their increasing responsibility for enforcing municipal bylaws and COVID-19 public health mandates, such as stay at …

An Examination Of External Threats On Romantic Behaviour In People With Low Self-Esteem, Melanie Christoforou

Theses and Dissertations (Comprehensive)

Establishing close bonds with others is more difficult for those with lower (vs. higher) self-esteem, especially when interpersonal risk is salient. The literature on risk regulation has focused predominantly on how self-esteem moderates responses to internal relationship concerns such as relationship insecurities and acute doubts about a romantic partner’s regard. However, little research has examined how people react when external forces, such as financial strain and health concerns, threaten to jeopardize their bonds with their romantic partners. The present research examines whether self-esteem affects how people regulate relational risk elicited by external stressors. I also examine whether self-protective responses differ …

Adrift In Uncharted Waters: A Case Study Of A Muslim Family Involved With Child Protection Services In Ontario, Bibi Baksh

Theses and Dissertations (Comprehensive)

This dissertation sought to understand how Muslims experience mandated child protection services in Ontario within the Canadian (and specifically, Ontarian) socio-political context. Ongoing experiences of racism, xenophobia, and Islamophobia within systems that intersect with child welfare, including schools and the criminal justice system, have compounding effects on Muslim families who are singled out politically and socially. Drawing from trends in child welfare literature, policy initiatives, and practices that consider the system’s impacts upon racialized peoples, this research contributes to the discourse by highlighting religious diversity as an under-investigated source of discrimination. Set against systemic challenges inherent in the child protection …

Changes In Lake Drainage In The Western Canadian Arctic, Dilshan Kariyawasam, Philip Marsh Dr

Theses and Dissertations (Comprehensive)

Nearly half of all Pan-Arctic lakes are situated in the Canadian Arctic, with many of these lakes being of thermokarst origin. Thermokarst lakes are sensitive to changes in the surrounding environment, making them useful indicators to examine the condition of hydrological systems in response to rapid climate warming, a trend which has been well observed in the Canadian Western Arctic. In this study, we use aerial photography to quantify lake area and count changes for lakes in the Inuvik-Tuktoyaktuk region, between 1950 and 2004. A combination of aerial photography and Landsat imagery were used in identifying drained thermokarst lake basins …

The Avian Hippocampal Declarative Memory System, Chelsey C. Damphousse

Theses and Dissertations (Comprehensive)

Across Mammalia, memory has long been dissociated into multiple component systems specialized to process specific facets of experience. Among these segregated systems, declarative memory is processed by the hippocampus and surrounding structures, which have collectively been referred to as the hippocampal declarative memory system (HDMS). The HDMS, in turn, can be further divided into parallel streams dedicated to the processing of spatial versus object identity based information, commonly discussed as the ‘what’ and ‘where’ streams. While we know that the organization of the HDMS is conserved in humans, nonhuman primates, and rats, evidence outside Mammalia is lacking. Here HDMS homology …

An Analysis Of Collective Efficacy As A Predictor Of Gun Violence In Toronto, Carly Richards

Theses and Dissertations (Comprehensive)

There has been a 42% increase in gun violence in Canada since 2013, largely due to increases in Toronto (Statistics Canada, 2022a). To gain a better understanding of this phenomenon, this study evaluated collective efficacy as a predictor of gun violence. Seven correlates of collective efficacy were identified including, low economic status, ethnic diversity, mobility, family disruption, employment rate, low educational attainment, and youth percentage in a population. This study included data from the City of Toronto’s Open Data Portal and the 2016 Canadian Census. The data were pulled from various datasets and then were reorganized into one file, which …

The mummichog (Fundulus heteroclitus) is a small-bodied estuarine fish that inhabits the North American east coast and is often used as a model adult saltwater fish in environmental bioassays. This study aimed to describe gonadal development and gene expression levels in five-week-old mummichog under control conditions and following 17α-ethinylestradiol (EE₂) treatment in order to better understand the susceptibility of sex determination (SD) and gonadal differentiation (GD) processes following contaminant exposure. In the first experiment, eggs were fertilized, collected and incubated in the laboratory for three weeks, then yolk-sac larvae were grown out for five weeks and …

Femme Ex Machina: Sex Robots, Embodiment, And Posthuman Subjectivity, Julia A. Empey

Theses and Dissertations (Comprehensive)

Andrea Dworkin warned in her 1974 book Woman Hating that men would soon develop the technology to “create the sex objects that will gratify them” (199). This dissertation investigates one of those technologies: sex robots, as mediated through science fiction film and literature. While the sex robot is still an emerging technology, its embodiment, particularly when female-rendered, has been imagined and negotiated for centuries. Men creating women in a specific, desired image is not new, but the sex robot is currently being transformed from imagined representation to embodied subject. This dissertation traces a pattern of representation that has allowed us …
