2013 — Crossing the Racial Hiring Divide in Public Education: First Nation Teachers Encounters with Employee Fit, Merit, and White Racial InnocenceRésumé
In the Yukon Territory, significant social, political and legal efforts have been put in place to articulate equality between First Nations and non-First Nations people, not as equality based on good will, but equity as a legal right. These significant accomplishments in the advancement of First Nations rights include recent land claims agreements and self-government agreements, employment equity policy and staffing protocol. In contrast to these statements of legal equality, this study examines the ways in which hiring challenges encountered by First Nations teachers—as racialized individuals in Northern Canada—are made to appear normative and natural. The hiring challenges exist despite … Lire la suite

2015 — Resource Use and Ecological Population Structure of Lake Whitefish (Coregonus clupeaformis) Spawning Aggregations in Lake HuronRésumé
Lake Whitefish are a commercially and ecologically valuable freshwater species in Lake Huron. Recent environmental changes have had broad impacts on current populations, which threaten the sustainability of this fishery. To properly conserve this resource, multiple sub-populations in the lake must be adequately represented in management regimes. Of special importance are adult spawning aggregations, which collectively contribute to the productivity of the fishery. However, spawning aggregations in Lake Huron are perceived to represent multiple stocks, adding complexity to fisheries management. The current population structure for adult Lake Whitefish is not well understood at the lake wide scale, and previous assessments … Lire la suite

2017 — Variable habitat selection and space use among bullsnake (Pituophis catenifer sayi) populations: distance between seasonal habitats drives space useRésumé
The distribution of resources determines space use and habitat selection by snakes. Particularly in northern areas, the proximity of overwintering den sites to summering habitat likely influences space use. The resources driving seasonal movements among habitats may vary among populations and thus, space and habitat requirements may also vary. In addition, human modification may affect resource use by altering available habitats and resources. Although previous studies have reported differences in spatial ecology among populations, the driving factors of this variation remain to be addressed for many species. Bullsnakes (Pituophis catenifer sayi) reach their northern range limits in southern Saskatchewan, where … Lire la suite

2018 — Can Patient Characteristics at Intake Predict Patient Response to Therapist-Assisted, Transdiagnostic Internet-Delivered Cognitive Behavioural Therapy?Résumé
Internet-delivered interventions for anxiety and depression show promise in both their effectiveness at reducing symptoms and their efficiency in routine practice. Still, some patients do not benefit from these programs, and there is limited understanding of factors that predict patient response. The current study investigates predictors of patient response to the Wellbeing Course, a transdiagnostic, therapist-assisted internet-delivered cognitive behavioural therapy designed to treat depression and anxiety. Case files from 1201 patients who participated in a recent open trial of the Wellbeing Course were analyzed to examine predictors of dropout (i.e., withdrawing from the course before completing all modules) and symptom … Lire la suite

2023 — Treating comorbid insomnia in patients receiving transdiagnostic Internet-delivered Cognitive Behaviour Therapy for anxiety and depression: A randomized controlled trialRésumé
Studies have demonstrated that transdiagnostic Internet-delivered Cognitive Behavioural Therapy (ICBT) programs for patients experiencing anxiety and depression can produce large improvements in symptoms. Comorbid insomnia is common among individuals seeking treatment for anxiety and depression, yet transdiagnostic ICBT programs rarely target insomnia and many ICBT patients report that symptoms of insomnia remain after treatment. The current trial was designed to explore the value of including a brief intervention for insomnia alongside an existing transdiagnostic program (Wellbeing Course). A new insomnia intervention was developed using a patient-oriented approach to maximize ease-of-understanding and overall acceptability to patients. Patients were randomly assigned to … Lire la suite

2018 — Analyse Morphosemantique et Contextuelle Du Mot et du Terme en Langue Generale et en Terminologie.Résumé
As language units consisting of spoken sounds and their written representation which operate as carriers of meaning, words and terms have been major objects of study on the convergence and divergence between general language and specialized language. Generally, terms are considered as special kind of words, but terminological arguments see them as basic terminological units used to designate concepts pertaining to specialized discipline, while words have been presented as units for general usage and for linguistic analysis. Linguists and terminologists argue that the similarity between words and terms is due to the morphological structure which they both have, resulting from … Lire la suite

2024 — Numerical study of dam break flow using shallow water equations with particle method approachRésumé
A significant concern in fluid dynamics is the dam-break phenomenon, which involves the sudden release of water when a dam breaks down. This event is made more complex due to the presence of obstructions, such as both natural and artificial elements, which can alter the flow of the water. The Moving Particle Semi-Implicit (MPS) method is a numerical method used in Computational Fluid Dynamics (CFD), which combines the advantages of semi-implicit and particle methods. The method has been developed to help simulate water flow behavior after a dam-break. This method breaks the domain into pieces referred to as particles, each … Lire la suite

2016 — "Fighting the Wrong War": Radical Pacifists and the Vietnam Antiwar Movement, 1962-1964Résumé
The Vietnam antiwar movement developed in stages that reflected the escalation of American involvement in South Vietnam. Between 1962 and 1964 radical pacifist leaders responded to this escalation by questioning the legitimacy of an American military presence in South Vietnam, identifying the issues of supporting a troubled national government that allegedly failed to meet its commitments to social justice, and challenging the foundational Cold War policies that defined American involvement in Southeast Asia. Through their collected response, the radical pacifists concluded that America’s military intervention against Communism in South Vietnam could not succeed because of the political, social, and economic … Lire la suite

2012 — Experimental Studies for Development of a Purification Process for Single and Mixed Amine SolventsRésumé
Amine solvents used for the removal of CO2 from flue gas are subject to solvent degradation, which results from the reaction of impurities in the gas stream. This leads to the formation of degradation products, which could lead to many operational problems such as changes in the solvent absorption capacity and physical properties. Amine thermal (distillation) or non-thermal (ion-exchange or electrodialysis) reclamation are usually used to purify the solvents. In post-combustion CO2 1- The reclamation process might not effectively handle single or blended amine solvents. The solvent recovery could be low while its content in the waste stream could be … Lire la suite

2020 — Cost-Sensitive and Semi-Supervised Learning for FraudRésumé
Given the magnitude of e-auction transactions, it becomes challenging to safeguard consumers from dishonest sellers, such as shill bidders. Shill Bidding (SB) is a predominant auction fraud that is driven by modern-day technologies and clever scammers. The difficulty of identifying the behavior of sophisticated fraudsters and the scarcity of training dataset, hinder the research on SB detection. The first part of this thesis aims to address these two difficult problems. We first define two new SB patterns and implement other existing SB patterns. Next, we develop a reliable SB dataset. This development requires crawling commercial auctions and bidder history, preprocessing … Lire la suite

2013 — Identification and Characterization of Developmentally Regulated Components of the Stress Axis in Petromyzon MarinusRésumé
Genes resembling elements of the Corticotropin releasing hormone (CRH) receptor-ligand system (CRH system) have been identified in invertebrate species and suggest the CRH system has existed, in some form, for approximately a billion years. It is theorized that vertebrates inherited components of the CRH system from an invertebrate ancestor. The association of the CRH system with the stress response, however, is specific to vertebrate species and theorized to have accompanied the development of hypothalamic pituitary (HP) axes, specifically the HP interrenal (HPI) axis in fish. A functional HPI axis has recently been suggested in the lamprey species Petromyzon marinus, a … Lire la suite

2014 — Life History, Nurse Empathy, and Aggressive Behaviours in Individuals with DementiaRésumé
Dementia is common among long term care (LTC) residents and has many implications for their quality of life. Individuals with dementia often present with behavioural disturbances such as aggression (e.g., destructive actions toward persons, objects, or the self) that negatively affect their quality of life and may result from unmet needs (Whall et al., 2008). Egan et al. (2007), using a very small patient sample (N = 4; no control group), successfully piloted an intervention intended to influence professional caregivers’ behaviour toward residents, and thus decrease aggressive behaviours by presenting staff members with life histories of the residents. The goal … Lire la suite

2019 — The Influence of Hormonal Fluctuation on Stress-Induced Smoking Cravings in WomenRésumé
Women experience greater difficulties in quitting smoking, though the hormonal factors contributing to this sex difference remain to be clarified. Increased smoking has been observed in the late luteal phase of the menstrual cycle and the current study aimed to clarify the role that changes in reproductive hormones may play in explaining these cycle effects. Furthermore, it tested the hypothesis that stress-induced smoking cravings are more pronounced during the luteal phase. To this end, twenty-two smoking women underwent two laboratory sessions–one in the mid-follicular phase and the other in the late luteal phase–involving an in-vivo smoking cue task, administered before … Lire la suite

2020 — De la terminologie à la socioterminologie: étude de l’implantation terminologiqueRésumé
Terminology (as a discipline) can be described as the scientific study of all the terms of a particular domain, used in the specialty languages, while socioterminology is a branch of terminology that is characterized by the study of the social circulation of terms and their appropriation, which implies the analysis of language practices, discursive functioning and the historical course of terms related to history of ideas. Terminological implantation therefore is seen as one of the means by which official terms can be circulated in a language of a specialized field or society. This means that implantation of official terms (proposed … Lire la suite
