The purpose of this study was to combine these areas of research and examine how attachment views of self and others are associated with self and other models of… more Full Text: NURTURING DEVIANCE: EXPLORING THE ASSOCIATION BETWEEN ATTACHMENT AND CRIMINAL THINKING PATTERNS A thesis submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts …

Abstract: <p>The generation of polymer brushes by surface-initiated polymerization techniques has become a powerful tool for the creation of hybrid materials. Governed by the type and amount of polymer used in the modification, the chemical and physical properties of a surface can be tailored by polymer grafting. In this study, a commonly used polymer flocculant, polyacrylamide (PAM), was grafted… more Full Text: Grafting Polyacrylamide from the Surface of Activated Carbon for Flocculation Applications A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

Abstract: <p>Past research on parents' knowledge of concussion has shown that they understand the severity and consequences associated with the injury but have existing gaps in their knowledge for its management. This is a cause for concern due to the critical role parents play in their child's management process. This present study sought to address this area of concern with semi-… more Full Text: Navigating Uncertainty: Exploring Parents Knowledge of Concussion Management and Neuropsychological Baseline Testing A thesis submitted to the committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in …

Abstract: <p>This thesis presents an approach for automated grading of UML Use Case diagrams. Many software engineering courses require students to learn how to model the behavioural features of a problem domain or an object-oriented design in the form of a use case diagram. Because assessing UML assignments is a time-consuming and labor-intensive operation, there is a need for an automated grading… more Full Text: AUTOMATED GRADING OF UML USE CASE DIAGRAMS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, Ontario, …

Abstract: <p>Mineral feedstocks, including alkaline mine wastes, can sequester CO2 as a dissolved phase (e.g., HCO3-) or a solid carbonate via enhanced rock weathering (ERW). For this thesis, the release of easily accessible Ca and Mg from non-carbonate sources was determined for kimberlite residues from several diamond mines and commonly proposed ERW rock types, including wollastonite and olivine.… more Full Text: PREDICTING AND MONITORING DRAINAGE CHEMISTRY DURING MINERAL WEATHERING FOR CO2 SEQUESTRATION A thesis submitted to Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

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 Full Text: Affective Pain Hypersensitivity in the Amygdala Kindling Model of Temporal Lobe Epilepsy A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

Abstract: <p>Migratory fish can influence the rivers where they spawn by depositing nutrients and organic matter which increase primary and secondary production. Past research in the Laurentian Great Lakes has focused on individual tributaries, accordingly, the spatial extent of subsidies and how environmental factors influence subsidies are not clear. To determine which tributaries received… more Full Text: Spatial Patterns of Resource Subsidies in Great Lakes Tributaries from Migratory Fishes A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

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 Full Text: Sex-specific spawning behaviour of lake whitefish in Lake Huron revealed by fine-scale acoustic telemetry A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty …
