The Selective Ion-Exchange Removal of Ammonia from Mining Wastewater

Zachary Guy Chartrand
The Canadian mining industry is a multi-billion-dollar effort and one of Canada’s largest industrial sectors, creating jobs and security across the country. Certain practices employed within the industry have led to great developments, while increasing productivity and reducing costs. One such practice is the use of nitrogen-based explosives, which have serious environmental repercussions, namely the introduction of large quantities of ammonia into the ecosystem through means of complex blends of wastewaters also containing various metals....

Parental Loss and Grief in the Neonatal Intensive Care Unit: A Systematic Review of Qualitative Evidence

Emily Reuvers
Premature and ill infants are admitted to neonatal intensive care units (NICU) for specialized medical and nursing care. Infants admitted to NICUs require the use of life sustaining technology and care from a multidisciplinary health care team. While in hospital, an infant’s prognosis and expected outcomes can dramatically change. Depending on the circumstances of their infant’s health, parents may choose to withdraw life sustaining treatment, or alternatively, face a future reality with the potential of...

Model and Characterization of a Passive Biomimetic Ankle for Lower Extremity Powered Exoskeleton

Brandon Fournier
Lower extremity powered exoskeletons (LEPE) allow people with spinal cord injury (SCI) to perform activities of daily living, such as standing, walking, or stair and ramp ascent/descent. However, current LEPE walk slowly and require extensive use of forearm crutches to maintain user stability. Consequently, this limits LEPE time of use and overall system performance. While the biological ankle is known to be critical for energy efficiency, speed, and stability in able-bodied walking, current LEPE do...

(U-Th)/He Thermochronology of the Aishihik Batholith, Central Yukon: Evidence for Stable Crust in the Cretaceous

Meghan Moher
The 190-180 Ma Aishihik batholith is located in southcentral Yukon in the North American Cordillera. Low-temperature (U-Th)/He thermochronology is used to assess the thermal history of the batholith and the surrounding host rock to provide an understanding of the Jurassic-Cretaceous tectonism. The Yukon Tanana terrane (YTT) shows a steady cooling of ~5°C/m.y from the Early Jurassic to the Late Cretaceous, when it reaches the surface. Sections of YTT adjacent to the batholith exhibits moderate cooling...

Chemical and Stable Isotopic Characterization of Geofluids from an Unconventional Natural Gas Field in New Brunswick, Canada

David Barton
The McCully gas field is located approximately 10 km from the town of Sussex in southern New Brunswick, Canada. There are currently 32 active natural gas production wells which produce dry gas and condensates from the low-permeability Hiram Brook sandstone and Frederick Brook shale members of the Carboniferous Albert formation. The wells range from inclined to vertical, and have been hydraulically fractured in order to stimulate production. This study provides new geochemical data that allows...

Oncolytic Viruses as a Potential Approach to Eliminate Cells That Constitute the Latent HIV Reservoir

Nischal Ranganath
HIV infection represents a major health and socioeconomic challenge worldwide. Despite significant advances in therapy, a cure for HIV continues to be elusive. The design of novel curative strategies will require targeting and elimination of cells that constitute the latent HIV-1 reservoir. However, such an approach is impeded by the inability to distinguish latently HIV-infected cells from uninfected cells. The type-I interferon (IFN-I) response is an integral antiviral defense mechanism, but is impaired at multiple...

Strong Optical Field Ionization of Solids

Azza Ben Taher
Population transfer from the valence to conduction band in the presence of an intense laser field is explored theoretically in semiconductors and dielectrics. Experiments on intense laser driven dielectrics have revealed population transfer to the conduction band that differs from that seen in semiconductors. Our research explores two aspects of ionization in solids. (i) Current ionization theories neglect coupling between valence and conduction band and therewith the dynamic Stark shift. Our single-particle analysis identifies this...

Effects of Health Claims on Consumption and Taste in Children: The Moderating Effects of Sex.

Alessandro Tirelli
Research on adults has shown that when certain energy dense foods (EDF) are marketed as ‘healthy’, consumption of these foods increases during a single eating occasion. However, the effect health claims can have on consumption and taste in pre-adolescent children is largely unknown. The main objective of this thesis was to examine how health claims influence energy intake (EI) and liking in pre-adolescent children. A between-subject experimental design was used, whereby 66 participants (34 girls...

An Expert System Integrated with a Bridge Information Management System (BrIMS), Cost Estimating, Deterioration Forecasting, and Linear Scheduling at the Conceptual Design Stage

Nizar Markiz
Major bridge stakeholders such as federal and provincial transportation agencies are in dire need for objective knowledge-based systems that assist decision-makers in the selection of bridge type. Besides that, estimating bridge construction costs at the conceptual design stage is an increasing necessity for accurate budgeting and effective allocation of funding. Whilst multiple bridge management systems have already been developed; they still possess major drawbacks pertaining to interoperability and integration with complex time and cost optimization-related...

Arctic Corridors and Northern Voices: Governing marine transportation in the Canadian Arctic (Ulukhaktok, Northwest Territories community report)

Natalie Ann Carter, Jackie Dawson, Colleen Parker, Jenna Joyce, Annika Ogilvie & Melissa Weber
Ship traffic in the Canadian Arctic nearly tripled between 1990 and 2015. Corridors have been mapped in the Arctic Ocean as part of the Low Impact Shipping Corridors Initiative co-led by Transport Canada, the Canadian Coast Guard, and Canadian Hydrographic Service. Low impact shipping corridors are the current framework for governing shipping in the Canadian Arctic. The intent of the low impact shipping corridors is to reduce the likelihood of marine incidents by providing predictable...

Chantal Lafleur
La stimulation multisensorielle (SMS; Snoezelen) utilisée avec des personnes atteintes d’un trouble neurocognitif majeur (TNC) est une intervention non pharmacologique qui vise la stimulation sensorielle ainsi que la relaxation corporelle pour favoriser le bien-être du patient. Cette recherche comporte deux études. La première étude, de nature qualitative, examine comment les salles de stimulation multisensorielle sont utilisées avec des patients atteints d’un TNC dû à la maladie d’Alzheimer (TNC-MA) dans quelques résidences pour personnes âgées de...

The Role of Proline Oxidation and Metabolome Dynamics During the Flight of Bombus Impatiens

Nadia Stec
Several insect species can use the amino acid proline as a major energy substrate, a unique characteristic of these animals. Although initially thought to be limited to blood feeding dipterans, studies revealed this capability may be more widespread. Recent work showed that the bumblebee Bombus impatiens can oxidize proline at a high rate, as measured using isolated flight muscle. However, its role as a metabolic fuel to power flight is unclear. To elucidate the extent...

Recherche développement d'un modèle didactique de l'enseignement-apprentissage de l'expérience esthétique de l'art postmoderne dans le cadre de la formation en arts visuels au collégial

Catherine Nadon
Cette recherche a pour but le développement d’un modèle didactique de l’enseignement-apprentissage de l’expérience esthétique de l’art postmoderne dans le contexte de la formation en arts visuels au collégial où trois principaux défis se posent. L’art postmoderne s’inscrit dans un nouveau paradigme caractérisé par la perte de critères esthétiques et un foisonnement des pratiques qui rendent ses contours difficiles à définir. S’ajoutent à cela une forte présence des préceptes modernistes en didactique des arts visuels...

Transitions of Care for People with Dementia: Predictive Factors and Health Workforce Implications

Gregory Huyer
As the population ages, policymakers struggle to cope with the increasing demands for home care and institutional long-term care. This thesis project focuses on factors associated with the transition from home to institutional care for people with dementia. Using health administrative data at a population level, we construct a multivariable model that estimates the time between home care initiation after dementia diagnosis and placement in a long-term care home. From the model, we identify protective...

De l’invisibilité à la visibilité sur le web : analyse d’un blogue consacré aux femmes ayant fait le choix de ne pas avoir d’enfant

Françoise Verschaeve
Cette thèse va porter tout particulièrement sur l’analyse d’un blogue consacré aux femmes qui, délibérément, ont fait le choix de ne pas avoir d’enfant, les « childfree ». Autour d’elles se développe tout un discours car elles vont à l’opposé des normes « socialement acceptables » préconisées par la société occidentale, qui prône un rôle de mère et d’épouse pour la femme dans un modèle familial ancestral pronataliste. Les « childfree » apparaissent dès lors...

The Self and the Other: An Attachment Perspective for Uncovering Dyadic Patterns of Intrapersonal and Interpersonal Distress

Josée Fitzpatrick
Psychosocial research is increasingly focused on attachment, specifically on the potential mechanisms associating attachment with psychological functioning (Cassidy & Shaver, 2016). In past decades, attachment research has sought to better understand the development of individual psychological distress as well as relationship distress, given its major impacts on the overall well-being of individuals. It is worth noting that researchers have identified specific intrapersonal and interpersonal factors that are important variables to consider in the link between...

Extremal Covariance Matrices

Youssouph Cissokho
The tail dependence coefficient (TDC) is a natural tool to describe extremal dependence. Estimation of the tail dependence coefficient can be performed via empirical process theory. In case of extremal independence, the limit degenerates and hence one cannot construct a test for extremal independence. In order to deal with this issue, we consider an analog of the covariance matrix, namely the extremogram matrix, whose entries depend only on extremal observations. We show that under the...

Les manifestations du leadership transformationnel par des conseillers pédagogiques

Claude Lachaîne
Les conseillers pédagogiques participent à la mise en œuvre des orientations du ministère de l’Éducation et de celles de leur conseil scolaire en matière d’enseignement afin de répondre aux besoins d’innovation, de communication et de collaboration des apprenants du 21e siècle. Outre leurs connaissances pédagogiques, leur propension pour l’innovation et leurs habiletés relationnelles, ils sont très peu préparés à exercer leur leadership quant à leurs fonctions d’agents de changement auprès de leurs collègues enseignants. L’objectif...

The Socio-Environmental Aspects of Students’ Food Literacy: An Exploratory Case Study of Two Ontarian High Schools

Alicia Martin
North American food environments have gone through dramatic shifts over the past six decades. During this period, we have witnessed the consolidation of a globalizing industrial agrifood regime, accompanied by new types of foods available and an excess of marketing. In recent years however, a growing number of scholars, environmentalists, rural organizations and consumers have highlighted the negative environmental and social impacts of this model of large scale, intensive monocultures. Another critique that has been...

Translation: Rights and Agency - A Public Policy Perspective for Knowledge, Technology and Globalization

Gaafar Sadek
Copyright law relegates translation to a secondary, or derivative, status, which means that publishing a translation requires the permission of the rights holder of the original. This thesis argues for the timeliness of revisiting the translation right by analyzing its foundations and its implications from a transdisciplinary public policy perspective. This is done by first studying the historical and philosophical foundations of copyright law itself where the translation right is housed, revealing questionable philosophical arguments...

The Study of Hereditary Spastic Paraplegia-Causing Gene DDHD2 Using Cell Models

Kevin Mongeon
Hereditary spastic paraplegia type 54 is a rare autosomal recessive neurological gait disorder characterized by paraplegia, muscle spasticity, and intellectual disability. This length-dependent distal axonopathy is caused by mutations in the DDHD2 gene, which encodes the intracellular phospholipase A1 DDHD2. Little is known about the molecular function of the DDHD2 protein, especially in the context of HSP54. Thus, there is a need to further investigate its molecular functions and investigate the impact of DDHD2 deficiency...

Quel imaginaire national à Taiwan? : l’évolution du portrait des religions populaires dans les manuels scolaires

Andréanne Laverdière
Cette enquête de terrain démontre que l’évolution de la représentation du religieux dans les manuels scolaires à Taïwan reflète une transition démocratique et identitaire « pacifique » (Allio, 2007, p. 788) ; celle-ci représentant une rare exception où les aspirations de la majorité populaire et les stratégies des acteurs politiques contrôlant les rouages de l’appareil d’État ont peu à peu coïncidé malgré leurs divergences idéologiques. L’État autoritaire a imposé jusqu’aux années 80 une vision de...

Increasing Willingness and Opportunities to Communicate in a Foreign Language with Machine Translation and Instant Messaging

Kizito Tekwa
Advances in technology over the last few decades have led to significant changes in the way we communicate. Technological innovation has been one of the reasons for the development of computer-mediated communication (CMC), which has had far-reaching implications in the private and professional lives of many people. Instant messaging (IM), which is one form of computer-mediated communication, has significantly gained popularity over the years and many scholars have examined its influence in areas including business...

Data Analytics-backed Vehicular Crowd-sensing for GPS-less Tracking in Public Transportation

Cem Kaptan
The widespread availability of sensors, improved computing, and storage capabilities, and ubiquity of networking services have led to the transformation of the conventional transportation services. Achieving the smart transportation goal can be either via dedicated or non-dedicated methods. The former denotes utilization of sensors that are explicitly deployed and configured for pre-defined sensing tasks whereas the latter exploits opportunistic and participatory sensing paradigms. With that motivation in mind, the contributions of this thesis are three-fold:...

Taking Reich’s Pulse: Putting New Music into Context

Anja Mileusnic-Plecas
Premiered on November 1st 2016, Steve Reich’s new work Pulse: For Winds, Strings, Piano and Electric Bass epitomizes 51 years of compositional development. Understandably, no formal or analytical discussions exist of this work, a lacuna that inspires the present research questions: Where does Pulse fall in relation to Reich’s overall style and technique? Is it a logical continuation of his compositional evolution? Does it make use of the techniques that distinguish him or does it...
