The overall objective of this study was to assess the abundance and distribution of microplastics within Lake Scugog catchment, Ontario. This was fulfilled through two tasks (i) the development of a microplastic particle budget for the lake catchment, and (ii) the determination of the… more Year: 2023, 2023

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 Year: 2023, 2023

Abstract: <p>Fungal pathogens adapt to environmental changes faster than their hosts, due in part to their adaptive mechanisms exhibited in response to stress. Ustilago maydis was used to investigate potential natural antisense transcript (NAT) RNA-mediated mechanisms that enhance fungal adaptation to stress. Of the 349 NATs conserved amongst U. maydis and two related smut fungi, five NATs were… more Year: 2023, 2023

Abstract: <p>Researchers have found associations between attachment, childhood adversity, and posttraumatic stress symptoms; however, the underlying mechanisms between these variables remains unknown. The present study explored the moderating effects of childhood adversity on the relationship between adult attachment and posttraumatic stress symptoms in two samples. In total, 533 undergraduate… more Year: 2023, 2023

Abstract: <p>Land cover change has the potential to alter the hydrologic regime from its natural state. Southern Ontario contains the largest and fastest growing urban population in Canada as well as the majority of prime (Class I) agricultural land. Expansions in urban cover at the expense of agricultural land and resultant 'agricultural intensification', including expansion of tile… more Year: 2023, 2023

Abstract: <p>Ego-depletion refers to the observation that using self-control at Time 1 (T1) in the sequential-task paradigm leads to worse self-control at Time 2 (T2; Baumeister et al., 1998). Self-control is often manipulated by varying the difficulty of the task used at T1. Recently, Wolff and colleagues (2020) suggested that failures to replicate the ego-depletion phenomenon may arise because… more Year: 2023, 2023

Through analysis of the history, function, and content of satire, this thesis presents stand-up comedy as an artform utilized for more than just simple laughter. Stand-up comedy, as a form… more Year: 2023, 2023

Abstract: <p>Concerns about climate change means that there is an urgent need to understand teachers' role in educating students about environmental issues and sustainability. However, little is known about teachers' environmental leadership and how that affects their competencies in the classroom, their general well-being and connections with nature, or what kinds of personality… more Year: 2023, 2023

Abstract: <p>Understanding the spatial ecology of large carnivores in increasingly complex, multi-use landscapes is critical for effective conservation and management. Complementary to this need are robust monitoring and statistical techniques to understand the effect of bottom-up and top-down processes on wildlife population densities. However, for wide-ranging species, such knowledge is often… more Year: 2023, 2023

Abstract: <p>The Minority Stress Model proposes that LGBTQ+ people experience stressors unique to their identity that negatively impact their mental well-being. The model also outlines that, in the case of the LGBTQ+ community, two minority coping resources - social support and connection to the LGBTQ+ community – may act as potential minority stress buffers; however, research has been unable to… more Year: 2023, 2023

Abstract: <p>In this work, a deep learning approach proposed by Valensise et al. [3] for extracting Raman resonant spectra from measured broadband CARS spectra was explored to see how effective it is at removing NRB from our experimentally measured "spectral-focusing"-based approach to CARS. A large dataset of realistic simulated CARS spectra was used to train a model capable of performing… more Year: 2023, 2023

Abstract: <p>This thesis examines racism in Argentina between 1880 and 1930. The governing elite's efforts to whiten the Argentine population at the end of the nineteenth century led to the erasure and discrimination of anyone who did not have Caucasian features: Afro-descendants, mulattos, mestizos, and creoles. However, in the 1930s, whitening policies proved to have limited success. On the… more Year: 2023, 2023

Abstract: <p>The scope of my scholarship has undergone a primarily interdisciplinary approach with an emphasis on historiographic scholarship and method, with the support of communication and sociological theory to underpin my core arguments in each chapter. I use the theories of Third Space, commodified racism, and common sense racism in combination to provide an in-depth analysis of prior… more Year: 2023, 2023

Abstract: <p>Faced with the intersecting environmental crises of the 21st century, conservation organizations are searching for practices that produce better, more sustainable outcomes. However, they have often relied on forms of conservation which shore up rather than disrupt settler relationships to land in the form of fortress conservation and assumptions about the human-nature dualism. In this… more Year: 2023, 2023

Abstract: <p>The seed oil of Carapa guianensis, known as Crabwood oil (CWO) and its fractionation was studied, focussing on chemical composition and physicochemical functionality. Compounds never reported before in CWO were identified, including limonoids such as Trichillin, ketostearic and hydroxyoleic acids. Yield of olein and stearin fractions correlated strongly with solvent polarity. Important… more Year: 2023, 2023

Abstract: <p>To examine comorbid pain sensitivity, temporal lobe epilepsy was modeled with a 42-stimulation amygdala kindling paradigm using rats. Sham and kindled rats' mechanical allodynia was not different before the formalin conditioned place aversion (FCPA) test. FCPA behaviour was not different, but twenty-four hours later kindled rats showed mechanical allodynia. Thermal sensitivity 48… more
