We consider the impact of free electrons occupying the t2g orbitals on the domain walls of an electron-doped perovskite ferroelectric. We build an analytical model based on Landau-Ginzburg-Devonshire theory, and a trio of tight-binding Hamiltonians for… more

Abstract: <p>Transracial adoption places the child with a family of a different ethnicity than their own. In the current study we qualitatively examine concerns associated with transracial adoption and investigate the relation between parent-child relationships and child social-emotional problems. Twenty-two adopted girls from China, 20 nonadopted Caucasian girls, and 23 nonadopted Chinese-Canadian… more

Abstract: <p>The traditions of spirituality and meditation have been found to connect to psychological health in the form of increased happiness, empathy, and decreased anxiety. The present study aimed to better understand how these practices might connect to such beneficial outcomes. A sample of 363 undergraduate student participants completed a questionnaire that measured their meditation practice… more

Abstract: <p>Lake whitefish (Coregonus clupeaformis) are ecologically, economically, and culturally significant across their range, yet little is documented about the species' spawning behaviour. Recruitment of lake whitefish has dramatically declined over the past two decades across many regions of the Laurentian Great Lakes, most notably in lakes Huron and Michigan, prompting research efforts… more

Abstract: <p>Coherent anti-Stokes Raman scattering (CARS) microscopy is a label-free chemical imaging modality that uses CARS as a contrast mechanism to spatially resolve materials based on their molecular vibrational spectra. Due to the presence of a non resonant background that obfuscates the chemical information contained in CARS spectra, CARS images suffer from poor contrast and cannot be readily… more

Abstract: <p>In Ontario, the dominant cash crop rotations consist of soybean (SB), which is a leguminous crop grown in rotation with maize (MZ) and winter wheat (WW). In addition to these crops, some farmers integrate cover crops (CC) into crop rotation, especially during the fallow period and winter seasons, to reduce nitrogen (N) losses via nitrate (NO3-) leaching and emission of N2 and the… more

Abstract: <p>Authenticity has been demonstrated as an important factor in relationships and sexual health (Impett et al., 2006; Impett, Breines, & Strachman, 2010). Although authentic behaviour is generally beneficial, sharing our true thoughts, feelings, and desires may be especially difficult in sexual contexts. Existing research has demonstrated that individuals find sexual communication… more

Abstract: <p>Children may be spending less time outdoors in nature than in previous generations, with one potential reason being parents in their role as 'gatekeepers' to the outdoors. This study investigated how families are spending their time during the COVID-19 pandemic, and how parents may influence children's outdoor nature experiences. Parents (N = 121) from across Canada… more

However, more research is needed to validate their efficacy and understand how environmental conditions can influence sensor measurements. I assessed the performance of an in situ chlorophyll sensor under controlled environmental conditions… more

With improvements in technology correlating directly to improvements in video games, this has recently not been the case. One recent technology video games have not fully leveraged is Cloud technology. This Thesis investigates a potential solution for video games to leverage… more

Abstract: <p>Phenolic compounds are used in industry, such as agriculture and biotechnology, and inevitably end up in our environment. These compounds may serve as a phenolic precursor to produce raw materials for a wide range of applications. Chemical oxidation has been the common synthetic pathway to oxidize phenols and related compounds. However, traditional chemical approaches suffer from use of… more

Unfortunately, little research has been conducted on loose or commingled dental assemblages to determine if they are suitable samples for reconstructing bioarchaeological narratives of ancient human populations. The lack of… more

Abstract: <p>This thesis explores the shot-term relationship between exposure to ambient air pollution and human health through metrics such as mortality and hospitalization in Canada. We begin by detailing the organization and interpolation of air pollution data from its partially quality-controlled source form. Analyses of seasonal, regional and temporal trends of all major components of PM2.5, was… more

Outside of these examples, GST evidence is scarce, particularly for the Middle Paleolithic. An extensive assemblage of GST recovered from Nesher Ramla, an open-air hunting camp in Israel, presents the unique opportunity to study the role of GST within Middle… more
