Abstract: <p>The fate of silver nanoparticles (AgNPs) in surface waters determines the ecological risk of this emerging contaminant. In this research, the fate of AgNPs in lake mesocosms was studied using both a continuous (i.e. drip) and one-time (i.e. plug) dosing regime. AgNPs were persistent in the tested lake environment as there was accumulation in the water column over time in drip mesocosms… more

Abstract: <p>There is little research devoted to exploring psychology's historical and discursive development. Psychological knowledge is generally presented as the contributions of individuals, but without context. The social, political, and economic aspects of psychology's development are scarcely discussed, including how the discipline came to be considered a science. This thesis project… more

Abstract: <p>In 1915 U.S. Marines invaded Haiti. Driven first by the epidemiological dangers in Haiti, health and medicine was made a central tenet in administering the occupation. Useful for protecting the American Marines from disease, the Service d'Hygiene (the occupation-era Public Health Service) also served a hegemonic purpose. By bringing American biomedicine to sick Haitians, the Service… more

Abstract: <p>Recent declines in growth and condition of Great Lakes' lake whitefish (Coregonus clupeaformis) have been linked to ecosystem-wide changes stemming from the invasion of dreissenid mussels. To test the influence of invasive mussels on this commercially important coregonid species, we collected archived scale samples from ten Great Lake locations and analyzed long-term changes in… more

Abstract: <p>This research investigates urban climate governance through a case study of climate change adaptation policy making in the Canadian municipality of Vancouver, British Columbia (BC). It investigates the context in which the City of Vancouver was motivated to develop its climate change adaptation strategy (CCAS) by exploring the motivating factors and drivers behind the formulation of this… more

Abstract: <p>Stormwater ponds (SWPs) are a common feature in new urban developments where they are designed to minimize runoff peaks from impervious surfaces and retain particulate matter. As a consequence, SWPs can be efficient at retaining particle-bound nutrients, but may be less efficient at retaining nutrients that are present primarily in the dissolved form, like nitrogen (N). However, the… more

Abstract: <p>My thesis examines anthropomorphism and many avenues in which humans represent nonhumans to evaluate their own lives. Using Isabella Rossellini's <italic>Green Porno</italic> webseries, a collection of two-minute films starring Rossellini as a multitude of nonhumans with costumes transforming her into nonhuman, I posit that a new form of anthropomorphism -- one that… more

Abstract: <p>Nitrogen is a major constituent of agricultural fertilizers, and nitrogen inputs to stream water via runoff and groundwater lead to a variety of negative environmental impacts. In order to quantify the movement of nitrogen through aquatic food webs, fourteen streams with varying land uses across South-Central Ontario were sampled for two species of fish, freshwater mussels, and water for… more

A.D. 1000-1650) in south-central Ontario, specifically variables considered to be favourable to maize agriculture. Four analyses were undertaken: a geographic information system (GIS) comparative analysis of Late Woodland sites compared to random… more

Abstract: <p>Selenium is an essential trace nutrient to many organisms, yet in high concentrations it is toxic. Organic selenium is more bioavailable to aquatic biota than inorganic selenium, but is usually found in much lower concentrations. Algae are known to biotransform inorganic selenium into several organo-selenium compounds, but it is unknown whether any of these bioaccumulate in the food… more

Abstract: <p>This thesis analyzes the history of the Inter-American Schools Service (IASS), which ran under the auspices of the American Council on Education beginning in 1943. The program was defined as a private initiative aimed at spreading U.S. democratic values throughout the hemisphere for the mutual benefit of both the United States and Latin America. Yet the program was ultimately one facet… more

Abstract: <p>Near-hand benefits are seen when individuals are able to process targets more quickly, accurately, and with greater precision when a hand is placed near, rather than far from a target. One possibility is that near-hand stimuli recruit visual-tactile bimodal cells. Research reports that placing a hand near a target delayed immediate saccade onset and speeded delayed saccade onset. Study 1… more

Situated in the Vaca Plateau, at the nexus of the Belize River Valley, the Petén District of Guatemala, and the Maya Mountains, Minanha became a Late Classic polity capital that… more

Abstract: <p>Dreams that occur in bereavement have been mainly overlooked in the psychological literature. This study focuses on the most memorable dreams of the bereaved that contain imagery of the deceased. There were 52 participants who completed the study via email. The main goal of the study was to investigate the occurrence of common themes in the dreams that have the deceased as a character.… more

Abstract: <p>Silver nanoparticles (AgNP) released into aquatic environments could threaten natural bacterial communities and ecosystem services they provide. We examined natural lake bacterioplankton communities' responses to different exposures (pulse vs chronic) and types (citrate and PVP) of AgNPs at realistic environmental conditions using a mesocosm study at the Experimental Lakes Area. An… more

Abstract: <p>Benthic macroinvertebrtes (BMI) are functionally important in aquatic ecosystems; as such, knowledge of their community structure and function is critical for understanding these systems. BMI were sampled from ten lakes in each of two regions of south-central Ontario to investigate which chemical and physical variables could be shaping their community structure and function. Ten… more
