Addressing Systemic Barriers to Truth and Reconciliation in Canadian Higher Education Institutions
(University of Waterloo, 2022-06-24)Education served as a driving force for the colonization of Indigenous Peoples in what is now known as Canada. Today, education is essential for truth and reconciliation. In 2015, the Truth and Reconciliation Commission ... -
(In)visible Hero: Heroism as an Aid in the Extraction of Care Labour During the COVID-19 Pandemic
(University of Waterloo, 2022-06-24)This honours thesis examined the myriad ways in which discourse supported the extraction and overproduction of care labour through the use of heroism labels. Throughout the COVID-19 pandemic, the label of heroism was used ... -
Petrogenesis of Archean granitoids: Insights from inverse and forward modelling
(University of Waterloo, 2022-06-24)Archean granitoids are the earliest representation of continental crust on Earth. The Archean geological record is dominated by rocks of the tonalite–trondhjemite–granodiorite (TTG) suite, which are thought to have formed ... -
What do you think? Associations between social anxiety, mentalizing, and social competence in middle childhood.
(University of Waterloo, 2022-06-21)Every individual brings a unique perspective and understanding to the social world that they inhabit. This is particularly true of socially anxious children, who view their social environments as a place of potential ... -
Designing an Incentive-compatible Reward Scheme for Algorand
(University of Waterloo, 2022-06-21)Founded in 2017, Algorand is the first carbon-negative blockchain protocol inspired by proof of stake. Algorand uses a Byzantine agreement protocol to add new blocks to the blockchain. The protocol can tolerate malicious ... -
Test-Time Training for Image Inpainting
(University of Waterloo, 2022-06-21)Image inpainting is the task of filling missing regions in images with plausible and coherent content. The usual process involves training a CNN on a large collection of examples that it can learn from, to later apply this ... -
The Reproductive Effects of Municipal Wastewater Effluents
(University of Guelph, 2017-03-01)There is a growing concern that pharmaceuticals and other chemicals present in the effluents (sewage discharged into a river) from municipal wastewater treatment plants enter the aquatic environment, where they may affect ... -
An Assessment of the Spatial and Temporal Variability of Biological Responses to Municipal Wastewater Effluent in Rainbow Darter (Etheostoma caeruleum) Collected along an Urban Gradient
(PLOS, 2016-10-24)Municipal wastewater effluent (MWWE) and its constituents, such as chemicals of emerging concern, pose a potential threat to the sustainability of fish populations by disrupting key endocrine functions in aquatic organisms. ... -
Characterizing Transcriptional Networks in Male Rainbow Darter (Etheostoma caeruleum) that Regulate Testis Development over a Complete Reproductive Cycle
(PLOS, 2016-11-18)Intersex is a condition that has been associated with exposure to sewage effluents in male rainbow darter (Etheostoma caeruleum). To better understand changes in the transcriptome that are associated with intersex, we ... -
Rainbow trout exposed to benzo[a]pyrene yields conserved microRNA binding sites in DNA methyltransferases across 500 million years of evolution
(Springer, 2017-12-04)The objective of this study was to examine the regulation of DNA methylation following acute (24 h) and prolonged (14 d) exposure to low (1 ng/L) and high (10 ng/L) benzo[a]pyrene. However, with the recent release of the ... -
Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges
(Wiley, 2018-03-01)A framework is presented that is intended to facilitate the evaluation of potential aquatic ecological risks resulting from discharges of down-the-drain chemicals. A scenario is presented using representatives of many of ... -
Tissue storage affects lipidome profiling in comparison to in vivo microsampling approach
(Springer, 2018-05-03)Low-invasive in vivo solid-phase microextraction (SPME) was used to investigate the lipid profiles of muscle tissue of living fish. Briefly, mixed mode SPME fibers were inserted into the muscle for 20 min extraction, and ... -
Multiple Stressors in the Environment: The Effects of Exposure to an Antidepressant (Venlafaxine) and Increased Temperature on Zebrafish Metabolism
(Multidisciplinary Digital Publishing Institute, 2019-11-19)Aquatic organisms are continuously exposed to multiple environmental stressors working cumulatively to alter ecosystems. Wastewater-dominated environments are often riddled by a myriad of stressors, such as chemical and ... -
Impacts on Metabolism and Gill Physiology of Darter Species (Etheostoma spp.) That Are Attributed to Wastewater Effluent in the Grand River
(Multidisciplinary Digital Publishing Institute, 2020-11-25)The effluent from municipal wastewater treatment plants is a major point source of contamination in Canadian waterways. The improvement of effluent quality to reduce contaminants, such as pharmaceuticals and personal care ... -
Photocatalytic Degradation of Microcystins by TiO2 Using UV-LED Controlled Periodic Illumination
(Multidisciplinary Digital Publishing Institute, 2019-02-14)Toxic microcystins (MCs) produced by freshwater cyanobacteria such as Microcystis aeruginosa are of concern because of their negative health and economic impacts globally. An advanced oxidation process using UV/TiO2 offers ... -
High Throughput Sequencing of MicroRNA in Rainbow Trout Plasma, Mucus, and Surrounding Water Following Acute Stress
(Frontiers, 2021-01-13)Circulating plasma microRNAs (miRNAs) are well established as biomarkers of several diseases in humans and have recently been used as indicators of environmental exposures in fish. However, the role of plasma miRNAs in ... -
Endocrine Disruptor Impacts on Fish From Chile: The Influence of Wastewaters
(Frontiers, 2021-03-25)Industrial wastewaters and urban discharges contain complex mixtures of chemicals capable of impacting reproductive performance in freshwater fish, called endocrine-disrupting compounds (EDCs). In Chile, the issue was ... -
A 30-Year Study of Impacts, Recovery, and Development of Critical Effect Sizes for Endocrine Disruption in White Sucker (Catostomus commersonii) Exposed to Bleached-Kraft Pulp Mill Effluent at Jackfish Bay, Ontario, Canada
(Frontiers, 2021-04-22)Jackfish Bay is an isolated bay on the north shore of Lake Superior, Canada that has received effluent from a large bleached-kraft pulp mill since the 1940s. Studies conducted in the late 1980s found evidence of reductions ... -
