Advancing The Implementation Of Connectivity Conservation In Canada: A Case Study Of The Policy And Management Environment Of The Chignecto Isthmus Region, Rachel Hodgson

Theses and Dissertations (Comprehensive)

Connectivity conservation is a means to enable the unimpeded movement of species and the flow of natural processes to sustain life. Understanding how connectivity conservation functions between parks and protected and conserved areas is a key component of addressing the global biodiversity crisis. The governance and associated policy environment of protected and conserved areas is often complex, and it is challenging for practitioners to understand how connectivity conservation practices can function. In this case study, protected and conserved areas practitioners working in the Chignecto Isthmus region of New Brunswick and Nova Scotia, Canada were interviewed assist in better understanding the …

Nomological Network Retrieval: The Development Of A Methodological Process For The Review Of Knowledge Structures In Academia And Its Application To Marketing Scholarship, Mohammad Ali Simjour

Theses and Dissertations (Comprehensive)

The increasing supply of peer-reviewed marketing publications indicates that the scholarly community’s understanding of marketing phenomena has increased significantly. However, this significant increase also prevents individual scholars from gaining insight into marketing phenomena simply because the sheer number of publications make a manual review of the literature impossible. This is an important limitation mainly because the validity of knowledge development processes in marketing partially depend on the scholars’ comprehensive understanding of extant knowledge. In this dissertation, I develop a methodological process to address this limitation and enable scholars to gain insight into large samples of peer-reviewed publications. I then apply …

Theses and Dissertations (Comprehensive)

This study compared empathy among police officers undergoing mental health crisis de-escalation training in virtual reality and live action training modalities. The study included police officers across different police services in Ontario (N=63) and evaluated the efficacy of the Mental Health Crisis Response Training (MHCRT, Lavoie et al., 2020) program delivered across virtual reality and live action modalities against a control group that did not receive the training program. After collection of participants’ demographics, empathy scores, and de-escalation competency scores, a series of correlations, ANOVAs and ANCOVAs were conducted. Results showed that participants receiving MHCRT virtual reality and …

Investigating The Effects Of Disturbance And Competition On Establishment, Growth, And Reproduction Of The Endangered Ripariosida Hermaphrodita, Daniel Engelking

Theses and Dissertations (Comprehensive)

Ripariosida hermaphrodita (Virginia Mallow) is a perennial riparian plant with broad, maple-like leaves. It grows up to three meters high and is often found in large clonal patches, but sexually reproduces readily. While this plant may seem like a redoubtable competitor when growing in large colonies, it is declining across its range in North America. The only known occurrences in Canada are in southern Ontario. Prior to this study, no new populations had been recorded even though one of the known populations produces copious amounts of viable seed with potential to disperse. There are many hypotheses for its rarity, but …

“Anything From The Land Is Good”: Understanding How Community Gardening In Kakisa, Northwest Territories, Can Contribute To Indigenous Food Sovereignty, Michelle Malandra

Theses and Dissertations (Comprehensive)

Rates of food insecurity in Canada’s northern Indigenous communities are at levels that should constitute an emergency. Dominant explanations for these high rates of food insecurity often ignore the ongoing impacts of colonization and over-emphasize individual choices and nutritional guidelines developed by outsiders. The importance of holistic community health is ignored, along with the cultural and social values and practices that support community health and well-being, including traditional food systems. As the acute impact of climate change in the North threatens traditional food access, a shift toward an Indigenous food sovereignty approach in health and food policy is needed. With …

Discerning Friend From Foe: Systematic Revision Of Cuscuta L. Section Indecorae Using A Combined Ecological, Morphometric, And Phylogenetic Approach., Corey Burt

Theses and Dissertations (Comprehensive)

The genus Cuscuta (Dodder; Convolvulaceae) are obligate parasitic plants. In one clade known as section Indecorae, there are species which are considered pests that pose significant threats to agricultural crop production, while other species are rare or known only from historical records. Section Indecorae contains three species: C. coryli, C. warneri, and C. indecora (the latter with three infraspecific taxa: var. indecora, var. longisepala, and var. attenuata). The systematics of section Indecorae are not currently resolved. Cuscuta indecora has a long and complicated taxonomic history with many infraspecific varieties described, and …

The Contribution Of Phonological Overlap To The Cognate Effect: An Event-Related Potential Study Of Persian-English Bilinguals, Zahra Fotovatnia

Theses and Dissertations (Comprehensive)

The purpose of this dissertation was to examine the contribution of phonological overlap to visual word recognition. More specifically, this study aimed at testing the phonological account of the cognate effect (i.e., faster and more accurate mental processing of cognates than noncognates) in visual word recognition in Persian and English, which are languages with different scripts. The phonological account attributes the cognate effect to the phonological similarity of cognates (form and semantically related words) in addition to the conceptual similarity that cognates and noncognates (semantically related words) have and to the degree of phonological similarity between cognates in two languages. …

Kirtan In The Americas: Music And Spirituality In A Transcultural Whirlpool, Gustavo Moura

Theses and Dissertations (Comprehensive)

Kirtan (Sanskrit: कीर्तन; IAST: Kīrtana) is a broad term referring to various forms of devotional singing commonly done in South Asian traditions. It is a core practice in the Hindu and Sikh faiths that is becoming increasingly popular around the world among people of all ethnicities. Beyond its expected propagation within Hindu and Sikh diasporas, kirtan is also spreading among members of new religious movements such as ISKCON and the 3HO/Sikh Dharma, who may engage in this practice as part of their daily cultivation. Even more broadly, a form of what has been called “neokirtan” has been gaining popularity in …

“To Be Involved In A Meaningful Way”: Mobilizing Indigenous Knowledge In Environmental Monitoring Practices In Northern Ontario, Alanna Robbins

Theses and Dissertations (Comprehensive)

A steady shift in the environmental management literature encourages greater inclusion of traditional knowledge (TK) alongside Western science, much of it seeking to directly support Indigenous communities develop their own frameworks for environmental monitoring and stewardship. To date, little attention has been placed on research practices themselves as sites where interdisciplinary and intercultural work takes place to bridge between different knowledge systems and develop best practices for effective collaboration. Matawa Water Futures (MWF), the object of study for this thesis project, is a three-year water stewardship project involving Indigenous and non-Indigenous researchers, environmental managers, and community interns, working with the …

Statistical Models For Decision-Making In Professional Soccer, Sean Hellingman

Theses and Dissertations (Comprehensive)

As soccer is widely regarded as the most popular sport in the world there is high interest in methods of improving team performances. There are many ways teams and individual athletes can influence their own performances during competition. This thesis focuses on developing statistical methodologies for improving competition-based decision-making for soccer so as to allow professional soccer teams to make better informed decisions regarding player selection and in-game decision-making.

To properly capture the dynamic actions of professional soccer, Markov chains with increasing complexity are proposed. These models allow for the inclusion of potential changes in the process caused by goals …

A Departmental Dilemma: The Genesis Of Canadian Military Export Policy, 1945-1960, Paul Esau

Theses and Dissertations (Comprehensive)

Recent sales of Canadian military equipment to Saudi Arabia have highlighted a contradiction between Canadian policy on paper and in practice. This dissertation seeks to explain these contradictions by exploring the evolution of Canadian conventional military export policy in the key years between 1946 and 1960. It loosely divides this 15-year span into three periods, which correspond to the genesis of Canadian military export policy (1946-1949), its expansion and formalization (1950-1955), and its first existential challenge (1956-1960). With a particular focus on the Department of External Affairs, this work explores the political considerations and bureaucratic debates which shaped government decision-making …

Assessment Of Stream Metabolism And Associated Environmental Drivers In The Greiner Lake Watershed, Nunavut, Canada, Nicole Gotkowski

Theses and Dissertations (Comprehensive)

Stream metabolism is an ecological process that can be monitored to assess carbon cycling and productivity within a stream ecosystem. GPP (gross primary productivity) is measured as oxygen produced by autotrophs and ER (ecosystem respiration), which is measured by oxygen depleted by all living organisms. Complications arise when estimating GPP and ER in the Arctic because most methods require a period of darkness when GPP ceases, however, summer regimes of photosynthetically active radiation (PAR) do not reach zero. Furthermore, natural diffusion of oxygen from the atmosphere (k) must be accounted for but this requires extensive field work, thus posing problems …

Wildlife Value Orientations And Recreation Conflict: A Focus On Hunters And Non-Hunters In Alberta, Canada, Yuvana Sequeira

Theses and Dissertations (Comprehensive)

Parks and other forms of protected areas are considered a vital tool in the effective conservation of biodiversity. These areas also provide important spaces for nature-based tourism and recreation (NBTR), where activities such as hiking, swimming, canoeing, and socializing with friends and family often occur. In some cases, hunting may also occur within a protected area, but there is little understanding of how such activities affect the experience and overall satisfaction of other recreationists (and vise-versa). While NBTR is a popular and growing industry, there is limited research in Canada about the values of tourists and recreationists and the …

Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel

Theses and Dissertations (Comprehensive)

There are myriad methods offered in the “self-help industry” and on social media promising to improve happiness. Some messages are evidence-based, often drawn from positive psychology research, and suggest actions requiring time and effort, while other messages may offer feel-good platitudes that are devoid of meaningful guidance; we label this latter type of content “inspirational bullshit.” Across two manuscripts, we investigate the predictors of liking different kinds of positive self-help content, from meaningless randomly-generated phrases to vacuous positivity to evidence-based advice. In the first manuscript, across three studies, bullshit receptivity (a tendency to judge pseudo-profound statements as profound) and people’s …

Controls On Thermokarst Lake Water Balances In The Inuvik - Tuktoyaktuk Region, Evan J. Wilcox

Theses and Dissertations (Comprehensive)

There are tens of thousands of thermokarst lakes in the Inuvik-Tuktoyaktuk region, located in the northwest corner of the Northwest Territories, Canada. These lakes formed following the last glacial period in areas where ice-rich permafrost thawed and created depressions in the landscape. The Inuvik-Tuktoyaktuk region is one of the fastest warming regions in the world, leading to changing precipitation patterns, permafrost thaw and deciduous shrub expansion, all of which are affecting the water balance of thermokarst lakes. During the past several decades, lake expansion and contraction have been observed in response to fluctuations in precipitation. While these changes in lake …

Adding Women To The Conversation On Safe Consumption Sites: A Qualitative Interview Study With Poor And Marginalized Women Who Use Illicit Substances, Kaitlin Waechter

Theses and Dissertations (Comprehensive)

Women’s erasure from discourses pertaining to substance use and safe consumption sites (SCSs) means harm reduction efforts are developed through the male lens. This research seeks to discover why women do (or do not) access SCSs so as to determine if and how SCSs address the unique gendered needs of women who use illicit substances. Semi-structured qualitative interviews were conducted with 14 women-identified individuals who use illicit substances. Participants were recruited from a non-profit organization that offers harm reduction, but is not itself a SCS in order to capture a full range of perspectives on the SCS in their community. …

Investigating The Role Of Implicit Theories Of Relationships On The Interpretation Of Investments In Relationship Decision-Making, Sarah Wall

Theses and Dissertations (Comprehensive)

A person’s prior investment in their romantic relationship is a strong predictor of whether they remain committed to that relationship (e.g., Le et al., 2010; Rusbult, 1980a; 1983), and this pattern is often seen outside of interpersonal contexts as well (e.g., Arkes & Blumer, 1985; Olivola, 2018; Thaler, 1980). However, little research has considered the extent to which commitment-relevant decisions might be affected in a top-down way by people’s implicit theories of relationships (ITRs; Knee, 1998). I theorized that lay theories about how relationships work may affect the extent that people consider past investments when making decisions about continuing with …

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 …

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. …

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 …

Characterization Of The Clostridioides Difficile Glycosyl Hydrolase Ccsz, Brian Lowrance

Theses and Dissertations (Comprehensive)

Bacteria inhabit many of the harshest environments on Earth; persisting and thriving in conditions thought to be unsuitable for life. One common strategy to withstand these environments is the formation of a biofilm. Biofilm composition varies greatly, depending on the underlying community that produces it. Cellulose, a polymer consistently prevalent in biofilms, has been identified as a virulence factor in many pathogens and is suspected to be involved in pathogenesis by Clostridioides difficile. C. difficile is the #1 cause of hospital acquired diarrhea, which can range from mild to life-threatening infections. Biofilm formation is hypothesized to be involved in …

Navigating Waters: Experiences Of Filipino Canadian Identity Making In The Diaspora, John Felix Tolentino

Theses and Dissertations (Comprehensive)

Research states that while Filipino Canadians are the largest growing migrant population in Canada, they are the least represented and understudied subjects in the academy. The primary purpose of this qualitative study is to better understand the experiences of Filipino Canadians and how they create their identities in the diaspora. Since few studies take on a social work lens to explore these important stories, I attempt to unearth these experiences using these guiding questions: (1) How do Filipino Canadians integrate their cultural identity in the diaspora? (2) What are the sociopolitical and historical conditions that inform these identities? Following Charmaz’s …

Vapourized Cannabis Extract Administration Impairs Memory And Alters Neural Activity In Laboratory Rats, Megan Chladny

Theses and Dissertations (Comprehensive)

Although people have smoked cannabis for millennia, administration of cannabis by heating the dried plant material or distilled extracts to a temperature just below the combustion point (i.e., vapourization or "vaping") has rapidly increased over the past few years (Javadi-Payder, Cole, and Taffe, 2018; Manwell, Charchoglyan, Brewer, Matthews, Heipel, and Mallet, 2014). Conversely, most of the cannabinoid research using rodent models has used parenteral routes of administration to examine the effects of purified cannabis extracts such as ∆⁹-tetrahydrocannabinol (THC), making it difficult to directly compare laboratory research to human drug use. Building on previous studies showing that THC …

Distributed Spatial Data Sharing: A New Era In Sharing Spatial Data, Majid Hojati

Theses and Dissertations (Comprehensive)

The advancements in information and communications technology, including the widespread adoption of GPS-based sensors, improvements in computational data processing, and satellite imagery, have resulted in new data sources, stakeholders, and methods of producing, using, and sharing spatial data. Daily, vast amounts of data are produced by individuals interacting with digital content and through automated and semi-automated sensors deployed across the environment. A growing portion of this information contains geographic information directly or indirectly embedded within it. The widespread use of automated smart sensors and an increased variety of georeferenced media resulted in new individual data collectors. This raises a new …

Deep In The Shadows Of Loss: An Exploration Of Grief, Mourning, And Intellectual Disability, Cara Grosset

Theses and Dissertations (Comprehensive)

This qualitative research project explores grief and mourning experiences of people labelled/with intellectual disabilities subsequent to the death of someone important in their lives. The primary research question was: in what ways do people labelled/with intellectual disabilities experience grief after the death of a significant person in their lives? The need for a project of this kind is grounded in the lack of research and social work practice literature related to better understanding grief, mourning, and support experiences after a death from the perspective of people labelled/with intellectual disabilities. The dual purpose of this research is to better understand (and …

Distinctiveness And Similarity: How The Sub-Trait Facets Of The Big Five Self-Organize To Create Personality Types, Jonathan Thiessen

Theses and Dissertations (Comprehensive)

The belief that people can be placed within a personality typology has persisted for millennia. At least as far back as Hippocrates (ca. 460 BCE–370 BCE) people were believed to be of a kind based on the four humors—blood, yellow bile, black bile, and phlegm. Since then, there have been many conceptions of personality typologies. The Myers-Briggs Type Indicator and the Enneagram of Personality are likely the most well-known personality typologies among the general public. Despite their wide public usage, neither typology boasts strong empirical support. However, psychology continues to investigate personality for evidence of a typology of personality. In …

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 …

Transformations Towards Just Urban Sustainabilities: A Community Psychology Approach To Analyzing And Fostering Urban Changes, Bianca C. Dreyer

Theses and Dissertations (Comprehensive)

Cities are uniquely positioned to drive social change towards more just and sustainable futures. However, while discourses of ‘transformations towards sustainability’ have gained prominence, their focus on integrating equity and justice and tackling the root causes of current unsustainabilities is lacking. This document outlines a research endeavor aimed at analyzing and fostering urban sustainable transformations from a community psychology perspective. This research is based on the assertion that without radical change based in equity and justice considerations, transformative efforts fail. First, a theory of just urban sustainable transformations (JUST) is suggested that draws on urban transformations and just sustainabilities scholarship. …

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …
