Confronting Sexism In Science, Technology, Engineering, And Math (Stem): What Are The Consequences?, Eden J.V. Hennessey

Theses and Dissertations (Comprehensive)

Disparaging remarks that female scientists are ‘Distractingly Sexy’ (Waxman, 2015) and ‘Too Pretty to Do Math’ t-shirts (Amazon.com) highlight the common belief that women in science, technology, engineering and math (STEM) violate perceived gender norms. However, by confronting these beliefs, women may incur a ‘double-dose’ of hostility; once for being present in science, and again because of the confrontation itself (Kaiser & Miller, 2001). Across three studies, this research tested how women confronting sexism in STEM contexts would elicit and anticipate social costs. Study 1 showed that male participants rated a hypothetical female confronter in STEM higher in bossiness and …

Differences In Perceptions Of Aperture Crossing During A Virtual Reality Choice Reaction Task Between Non-Athletes And Varsity Athletes, Jaime Mitchell

Theses and Dissertations (Comprehensive)

Background: Vision will guide the actions and behaviors that allow us to circumvent environmental obstacles. When passing through a gap, individuals will consistently elicit a shoulder rotation (SR) if the gap is 1.4 times their shoulder width (SW) or narrower, with this behaviour being produced under various environmental conditions. Although a few studies have investigated perceptual predictions regarding gap passage, the effect of physical activity and the differences between trained and untrained athlete’s behaviours has not been examined. This study investigated the perceptual judgements of non-athletes and varsity athletes regarding the action they would utilize to pass through a dynamically …

Reading Across Different Orthographies: Urdu, Arabic, Hindi And English, Amna Mirza

Theses and Dissertations (Comprehensive)

Research on relationships across literacy skills for multiple languages suggests the need for a complex framework that includes linguistic typology as well as cognitive and cultural variables (Schwartz, Geva, Share, & Leikin, 2007). Literature shows that bilinguals activate both languages they know for all linguistic tasks regardless of which language is being used at the time (Kroll & Bialystok, 2013). In that case, learning a third or any additional language is qualitatively different than second language (L2) acquisition. Findings for readers of Roman scripts demonstrate that L1 reading and L2 proficiency influences L2 reading (Cummins, 1979). The current research examined …

Investigating The Role That Cognitive Defusion Plays Within Mindfulness, Amanda Desnoyers

Theses and Dissertations (Comprehensive)

Mindfulness has been shown to lead to reductions in psychological distress and improved well-being, but there is limited research on the mechanism of change. A cognitive shift in perspective has been suggested as a possible mechanism of change. Three different terms appear to refer to this shift in perspective: 1.Decentering, developed from cognitive behavioural therapy, involves the ability to observe one's thoughts and feelings as solely being events of the mind. 2. Defusion, developed from acceptance and commitment therapy, focuses on the ability to separate or distance from one’s thoughts, and 3. Metacognitive awareness, developed frommindfulness-based cognitive therapy, involves experiencing …

After arriving in Canada, refugee children continue to be at a disadvantage due to challenges related to language proficiency and literacy skills. The purpose of this study was to examine factors that contribute to the successes and challenges in language and literacy development in both languages, Arabic as the first language (L1) and English as the second language (L2) …

Do Early Community-Based Initiatives Predict Social Anxiety 20 Years Later?, Christina Dimakos

Theses and Dissertations (Comprehensive)

Social anxiety disorder is characterized by an extreme and persistent fear of embarrassment or scrutiny in social or performance situations. This condition is among the most common mental illnesses and is characterized by an early onset, chronic course, and significant associated health and social service costs. Nevertheless, it remains among the least recognized, researched, and treated mental health conditions. Critically, broader community characteristics have yet to be considered as valuable tools for disrupting the onset and maintenance of social anxiety. The present study examined the long-term impact of a comprehensive, holistic, community-based early childhood development initiative on social anxiety in …

The Complexity Of Canadian Anti-Communism, 1945-1967, Ian Muller

Theses and Dissertations (Comprehensive)

This dissertation argues that the history of anti-communism in English Canada between 1945 and 1967 is more diverse and complicated than traditionally acknowledged. Often dispersed throughout the scholarship as elements of other Cold War topics, including espionage, state surveillance, and policing, anti-communism is the central subject of this investigation. A series of case studies are used to analyze individual encounters with the state and civic engagement with the domestic threat of communism. The unique politico-cultural approach of this dissertation will bolster Canada’s Cold War historiography by investigating both public and private manifestations of anti-communism.

The intersections of public safety, the …

The Forgotten Front: British Home Defence And The Invasion Scare Of 1914, Alexander Maavara

Theses and Dissertations (Comprehensive)

Few issues have impacted the British people more than the historic fear or threat of invasion. From the Napoleonic Wars to the Second World War, the most “heroic” periods of British history have been those when the island faced possible invasion and destruction. This thesis seeks to address a gap in the history of Great Britain by examining the impact of Britons’ fear of invasion on British civil-military relations prior to and in the initial stages of the First World War. Following the 1911 Agadir Crisis, Britain’s defence establishment acknowledged the political and social influence that the fear of invasion …

Near-Surface Permafrost Ground Ice Characteristics And Ecological And Physical Drivers Of Transient Layer Ice Content In Discontinuous Permafrost, Jason Paul

Theses and Dissertations (Comprehensive)

Accelerated climate warming in northern regions is causing permafrost degradation, leading to the reduction of the areal extent of permafrost. Permafrost is the foundation for many northern ecosystems and communities, so its thaw can have important ecological and societal consequences. Thaw of ice-rich permafrost can cause subsidence of the ground surface proportional to excess ice content. Terrain settlement can cause ponding or damage to infrastructure. Following a surface disturbance that removes much of the vegetation cover, a shift in the ground thermal regime can cause an increase in active layer thickness and rapid thaw of the top portion of permafrost. …

Exploring Lactate’S Role In Appetite Regulation Following High-Intensity Exercise, Luke W. Vanderheyden

Theses and Dissertations (Comprehensive)

Background: Intense-exercise has demonstrated an appetite suppressing effect post-exercise, however the involved mechanisms are not well understood. Lactate appears to be one viable mechanism as it has been found to bind to receptors on acylated ghrelin to inhibit release in cell culture. As sodium bicarbonate (NaHCO₃) can alter lactate accumulation post-exercise without manipulating exercise-intensity, it presents an intriguing means to investigate lactate’s potential role. Purpose: To examine the role of lactate on appetite using NaHCO₃ to alter blood lactate concentrations during high-intensity exercise. Methods: Eight recreationally active males completed two identical exercise sessions of low-volume high-intensity interval …

Further, by employing the GMTL method and the mixed-potential integral equations (MPIE) method in a multiple scattering (MS) procedure, it enables an efficient and accurate approach to evaluate the current distribution on a cable harness with …

Empirical Correlations Between Rock Cutting Parameters And Excavated Rock Surface Rebound Hardness, Azupuri Germanus Ayerikujei Kaba

Doctoral Dissertations

"In field excavation, cutting tools operate on rock surfaces damaged from previous tool pass, yet, average intact rock properties are often used in field project estimations. This can result in overestimation of excavation time and cost. The ability to accurately correlate the damaged rock properties to the excavation parameters means more reliable estimates of project completion time and costs, and hence improved the application of mechanical excavation technology to a wider range of civil and mining industries.

The purpose of this research was to better understand the relationship between rock cutting parameters and the excavated rock surface hardness during mechanical …
