Abstract: <p>Depression during the transition into adulthood is a growing mental health concern, with overwhelming evidence linking the developmental risk for depressive symptoms with maternal depression. In addition, there is a lack of research on the protective role of socioemotional competencies in this context. This study examines independent and joint effects of maternal depression and trait… more Year: 2020, 2020

Abstract: <p>Forensic epistemology is the study of knowledge as it relates to forensic science and can be broken into four sources; intuitive, authoritative, logical and empirical. In a four-phase research approach, I explored reasoning skills (logical knowledge) used by crime scene experts and methods (empirical knowledge) for forensic case-specific experimentation. First, the reasoning skills of… more Year: 2020, 2020

Abstract: <p>The waterborne protozoan Giardia intestinalis cycles between the environmentally-resistant and infectious cyst and the metabolically-active trophozoite that adheres to the epithelial lining of the small intestine. Adhesion can trigger the innate immune response in epithelial cells, including the synthesis of the free radical nitric oxide (NO) that inhibits cell proliferation and… more Year: 2020, 2020

Abstract: <p>The contemporary denigration of poultry combined with the intensification of industrialized animal agriculture has deepened divides between humans and poultry, creating a disconnect that holds implications for both parties and the sustainability of North American food systems. This study explores how people with poultry keeping experience perceive these animals, how their views are… more Year: 2020, 2020

Abstract: <p>Brook trout (Salvelinus fontinalis) are declining across Ontario in both numbers and distribution, prompting concern for their future. Here, conventional, emerging, and predictive tools were combined to document brook trout occupation across seasons using streams in Haliburton County, ON as model systems. By using the Ontario Ministry of Natural Resources and Forestry's (OMNRFs)… more Year: 2020, 2020

Abstract: <p>Radionuclides occur in the environment both naturally and artificially. Along with weapons testing and nuclear reactor operations, activities such as mining, fuel fabrication and fuel reprocessing are also major contributors to nuclear waste in the environment. In terms of nuclear safety, the concentration of radionuclides in nuclear waste must be monitored and reported before storage… more Year: 2020, 2020

Abstract: <p>The "Orillia Asylum for Idiots" (1861 - 2009), Canada's oldest and largest facility for the care and protection of children and adults with disabilities, was once praised as a beacon of humanitarian progress and described as a "community within a community." Yet, survivors who lived in the facility during the post Second World War period, a time described as the… more Year: 2020, 2020

Abstract: <p>This study uses stable isotope analysis on both the organic and inorganic fractions of ostrich eggshell obtained from archaeological excavations in Mongolia, northern China, and southern Siberia. By establishing the δ13Corg, δ15N, δ13Cinorg, δ18O isotopic compositions of the eggshell of the Asian ostrich (Struthio asiaticus), this study provides insight into the maximum northern range of… more Year: 2020, 2020

Abstract: <p>This thesis examines the social impact of horses on French elites between 1150 and 1300. Using courtly literature, a veterinary treatise, manuscript illuminations, archeological studies, material artefacts, and account books, it explores the place of horses in elite society—practical and symbolic—and assesses the social costs of elite use and ownership of horses. While horses served… more Year: 2020, 2020

Abstract: <p>Postclassic (AD 900-1500) Maya diet at Ka'kabish, Belize was examined using stable carbon and nitrogen isotope analysis of human bone collagen, and stable carbon isotope analysis of bone structural carbonate. Isotope data were compared to skeletal and dental indicators of diet and disease, and dietary differences among burials excavated from chultuns (B-2, C-1, C-2, and C-3) at Ka… more Year: 2020, 2020

Abstract: <p>Partnerships for management of public parks have a long history, but little attention has been given to the current models of partnerships during a period of municipal austerity in Ontario. Using a qualitative assessment of transcripts from representatives of 10 municipal partner groups, this research considers what some of the current models are, the impact that they may have, and how… more Year: 2020, 2020

Abstract: <p>The objective of this thesis is to develop and implement a heritage plan for the Nassau Mills Complex, a locally-significant Euro-Canadian historical site that operated on what is now Trent University's campus in Peterborough, Ontario. Within the framework of public archaeology and Cultural Heritage Management (CHM), emphasis is placed on the importance of protecting the site and… more Year: 2020, 2020

Abstract: <p>The digital typesetting of mathematics can present many challenges to users, especially those of novice to intermediate experience levels. Through a series of experiments, we show that two models used to represent mathematical structure in these typesetting applications, the 1-dimensional structure based model and the 2-dimensional freeform model, cause interference with users'… more Year: 2020, 2020

Abstract: <p>Dairy goat farming has become increasingly popular in recent years in Ontario. This qualitative study done by semi-structured interviews, examines the why and the wherefore of the opinions held by dairy goat farmers in Ontario in regards to sustainable agriculture. It was found that these farmers feel that sustainable agriculture is important. These farmers believed their farms to be… more Year: 2020, 2020

Abstract: <p>The human cornea is required to exhibit specific material properties to maintain its regular shape under typical intraocular pressures which then allow for its correct optical functionality. In this thesis, the basis of continuum solid mechanics and the finite element method are introduced. We use finite element modelling to simulate the extension of an effective-1d, linear-elastic bar,… more Year: 2020, 2020

Abstract: <p>Mafic and ultramafic mine wastes have the potential to sequester atmospheric carbon dioxide (CO2) through enhanced weathering and CO2 mineralization. In this study, kimberlite residues from South African diamond mines were investigated to understand how weathering of these wastes leads to the formation of secondary carbonate minerals, a stable sink for CO2. Residues from Venetia Diamond… more Year: 2020, 2020

Abstract: <p>Natural populations are often difficult and costly to study, due to the plethora of confounding processes and variables present. This is of particular importance when dealing with managed species. Ungulates, for example, act as both consumers and prey sources; they also provide economic benefit through harvest, and as such, are of high ecological and economic value. I addressed… more Year: 2020, 2020

Abstract: <p>Forecasting future values of time series has long been a field with many and varied applications, from climate and weather forecasting to stock prediction and economic planning to the control of industrial processes. Many of these problems involve not only a single time series but many simultaneous series which may influence each other. This thesis provides methods based on machine… more
