To What Extent Do L1 Speakers And L2 Learners Have Productive Derivational Knowledge, Emi Iwaizumi Oct 2019

To What Extent Do L1 Speakers And L2 Learners Have Productive Derivational Knowledge, Emi Iwaizumi

Electronic Thesis and Dissertation Repository

The present study investigated the extent to which L1 English speakers and L2 English learners could produce the derivatives of 90 head words in a decontextualized derivative recall test. This research also examined whether productive derivational knowledge varied between institutional levels (i.e., graduate, undergraduate, and high school) and vocabulary levels (i.e., 1000-5000). The results indicated that L1 speakers had greater productive derivational knowledge than L2 learners. However, no significant differences were found between L1 speakers and the advanced L2 learners. The results also indicated that the degree to which L2 learners have productive derivational knowledge significantly varied between ...


Functionalization Of Indoles And Donor-Acceptor Cyclopropanes And Their Application Towards The Total Synthesis Of Tronocarpine And Dippinine B, Lauren C. Irwin Oct 2019

Functionalization Of Indoles And Donor-Acceptor Cyclopropanes And Their Application Towards The Total Synthesis Of Tronocarpine And Dippinine B, Lauren C. Irwin

Electronic Thesis and Dissertation Repository

The work disclosed in this dissertation outlines novel reactions involving indoles and their applications towards the total synthesis of natural products, tronocarpine and dippinine B.

Showcased in Chapter 2 is a novel mode of activation for donor-acceptor cyclopropanes via an external hydrogen bond. The hydrogen bond increases the cyclopropane’s electrophilicity permitting indole nucleophiles to open the ring. The result is 3-postion functionalized indoles.

An external hydrogen-bond donor, HFIP (1,1,1,3,3,3-hexafluoroisopropanol), is used as a solvent to provide the medium necessary for favourable hydrogen-bond interaction with donor-acceptor cyclopropanes. Hydrogen bond activation of donor-acceptor cyclopropanes was successful ...


Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan Oct 2019

Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan

Electronic Thesis and Dissertation Repository

Using stable isotope measurements of inert tissues to determine origins and migratory patterns is well established. However, isotopically determining nutritional origins of lipids, the primary fuel of migration, has not been attempted. I explored isotopic links between diet and stored lipids in captive White-throated Sparrows (Zonotrichia albicollis) and true armyworm moths (Mythimna unipuncta) using δ13C and δ2H measurements. Isotopic discrimination between body lipids and diet was established as linear calibration functions. Isotopic uptake following a diet switch in moths was used to trace lipid accumulation over time. Isotopic correlations between breath metabolic by-products of fed and ...


Moloch's Children: Monstrous Techno-Capitalism In North American Popular Fiction, Alexandre Desbiens-Brassard Oct 2019

Moloch's Children: Monstrous Techno-Capitalism In North American Popular Fiction, Alexandre Desbiens-Brassard

Electronic Thesis and Dissertation Repository

Deriving from the Latin monere (to warn), monsters are at their very core warnings against the horrors that lurk in the shadows of our present and the mists of our future – in this case, the horrors of techno-capitalism (i.e., the conjunction of scientific modes of research and capitalist modes of production). This thesis reveals the ideological mechanisms that animate “techno-capitalist” monster narratives through close readings of 7 novels and 3 films from Canada and the United States in both English and French and released between 1979 and 2016. All texts are linked by shared themes, narrative tropes, and a ...


Progress Toward Durable Icephobic Materials, Matthew J. Coady Oct 2019

Progress Toward Durable Icephobic Materials, Matthew J. Coady

Electronic Thesis and Dissertation Repository

Ice accumulation is a major engineering challenge in many fields including aerospace, power generation, transportation, and infrastructure. A variety of solutions are being researched to address this challenge. Perhaps the most promising method of combating ice accumulation is by applying coatings with low values of interfacial ice adhesion strength, τice. Icephobic materials are those with ice adhesion below 100 kPa, and it has been shown that passive delamination can occur on surfaces with τice below 20 kPa. While various low adhesion surfaces have been prepared, durability concerns pervade applications where surfaces experience repeated icing or freeze-thaw cycles, mechanical ...


Airborne Topological Acoustics, Xingxing Liu Oct 2019

Airborne Topological Acoustics, Xingxing Liu

Electronic Thesis and Dissertation Repository

Advances in topological acoustics are leading to potential development for noise attenuation, ultrasonic imaging, sound manipulation, and information delivering, etc. Recently, ideas and methodologies from condensed-matter physics, such as the quantum Hall effect (QHE), the quantum spin Hall effect (QSHE), and the quantum valley Hall effect (QVHE), combined with configurations of sonic crystals and metamaterials, have been investigated in manipulating acoustic transmissions in the form of one-way edge modes and defect-immune protected acoustics. However, many related studies are still in their infancy and mostly rely on bulky, noisy, overly complicated, untunable and narrow-band-effective facilities, and so it is highly desirable ...

Feasibility And Reliability Of A Commercially Available Stretch-Sensitive Sensor For Neck Movement, Iyad Al-Nasri Oct 2019

Feasibility And Reliability Of A Commercially Available Stretch-Sensitive Sensor For Neck Movement, Iyad Al-Nasri

Electronic Thesis and Dissertation Repository

The ability to move the neck is usually a good indicator of neck health. However, the tools currently available to measure neck range of motion rely on gravity and the clinician's ability to accurately line the instruments on specific landmarks of the body. This study explored whether a commercially available wearable sensor, C-Stretch® that is flexible and lightweight can capture the functional performance of cervical motion across testing sessions. Furthermore, an assessment of the C-Stretch® against Aurora NDI, an electromagnetic tracking system was explored to determine the feasibility of transforming raw capacitance data into degrees of motion. Finally, a ...

Hegel Avec Kleist: On Marriage, Colby A. Chubbs Oct 2019

Hegel Avec Kleist: On Marriage, Colby A. Chubbs

Electronic Thesis and Dissertation Repository

This thesis investigates Hegel’s account of marriage in his Philosophy of Right as an ontological impasse which bears witness to a splitting and deadlock within his broader conception of ethical life (Sittlichkeit). As such, it is our aim to situate an opacity within the Hegelian self-conscious subject, as opposed to the subject attaining an inner self-awareness and transparently reflexive agency and, to this end, we put Hegel into conversation with his contemporary, Heinrich von Kleist. From this standpoint, we show in the first chapter how the thinker against whom Hegel formulates his account of marriage is Immanuel Kant who ...


Characterization Of Wilms' Tumour 1 (Wt1) As A Biomarker For Fibrosis In Duchenne Muscular Dystrophy, Patrick Murphy Oct 2019

Characterization Of Wilms' Tumour 1 (Wt1) As A Biomarker For Fibrosis In Duchenne Muscular Dystrophy, Patrick Murphy

Electronic Thesis and Dissertation Repository

Duchenne muscular dystrophy (DMD) is the most common inherited pediatric muscle dystrophy. It is characterized by muscle degeneration, resulting in fibrosis that is a significant impediment to both endogenous muscle repair and any potential regenerative strategy. At present, there are few therapies that specifically address fibrosis and microenvironment improvement, but one possibility rests in targeting the Wilms’ tumour 1 (Wt1) protein. Wt1 is a zinc finger transcription factor, recently shown to be expressed in fibrotic conditions such as Dupuytren’s disease and pulmonary fibrosis. This thesis examines the expression pattern of Wt1 in several mouse models of DMD, through both ...


How Do Humans Process Magnitudes? An Examination Of The Neural And Cognitive Underpinnings Of Symbols, Quantities, And Size In Adults And Children, Helen Moriah Sokolowski Oct 2019

How Do Humans Process Magnitudes? An Examination Of The Neural And Cognitive Underpinnings Of Symbols, Quantities, And Size In Adults And Children, Helen Moriah Sokolowski

Electronic Thesis and Dissertation Repository

A striking way that humans differ from other species is our unique ability to represent and manipulate symbols. This ability to process numerical magnitudes symbolically (e.g., ‘three’, ‘3’) is widely thought to be supported by an ancient system that evolved to process nonsymbolic numerical magnitudes (i.e., quantities). In this thesis, I present four empirical studies to uncover whether symbolic representations are indeed supported by the system that evolved to process quantities, or if symbolic representations are sub-served by a similar but ultimately distinct system.

In experiments 1 and 2, I investigate how the adult brain processes symbols and ...


The Creation And Application Of A Validated Tool To Measure The Impact Of Mobile Standing Desks On Undergraduate Students' Sedentary Time, Marc S. Moulin Oct 2019

The Creation And Application Of A Validated Tool To Measure The Impact Of Mobile Standing Desks On Undergraduate Students' Sedentary Time, Marc S. Moulin

Electronic Thesis and Dissertation Repository

Undergraduate students (UGS) are highly sedentary, which may elevate their health risks. However, before the effectiveness of an undergraduate sedentary time (ST) intervention can be assessed, accurate and applicable measurement tools need to be identified. The overall purposes of this research program were to first, evaluate the validity of two weekly ST questionnaires compared with criterion data in homogenous samples of UGS (Studies 1 and 2); and second, to measure the effect of providing UGS with mobile standing desks for one-week (Study 3) and one-month (Study 4), while also exploring students’ perceptions about using the desks. Each study built on ...


Adolescents’ Perceptions And Responses To Peer Mental Health Challenges And Problematic Behaviours Following A Social-Emotional Learning Program, Jessica Sommers Oct 2019

Adolescents’ Perceptions And Responses To Peer Mental Health Challenges And Problematic Behaviours Following A Social-Emotional Learning Program, Jessica Sommers

Electronic Thesis and Dissertation Repository

Vulnerable youth may be more susceptible to developing problematic behaviours and mental health challenges, including anxious and depressive symptoms, suicidal ideation, substance misuse, and unhealthy relationships. Social-emotional learning programs like The Healthy Relationships Plus Program (HRPP) can foster positive youth development by including training on mental health literacy, developing skills in help-seeking, and providing opportunities to practice difficult conversations. This study explored youth’s responses to hypothetical challenges faced by peers with a group of sixty-three adolescents who had participated in the HRPP. Responses to four distinct scenarios were collected to examine youths’ perceptions of various challenges and problematic behaviours ...


Response Of Stream Biofilm Function To Pulsed Increases In Velocity And Nutrients: An Artificial Stream Study, Chris Lucas Oct 2019

Response Of Stream Biofilm Function To Pulsed Increases In Velocity And Nutrients: An Artificial Stream Study, Chris Lucas

Electronic Thesis and Dissertation Repository

Pulsed increases in flow within streams alter abiotic conditions such as nutrient concentrations and velocity which can influence the function of stream ecology, including biofilms. A 31-day artificial stream experiment at Thames River Experimental Stream Sciences (TRESS) Centre, London, Ontario, assessed the response of stream biofilm function (decomposition, primary production, community respiration) to individual and combined increases in velocity and phosphorus associated with a 48-hour hydrological pulse event. There was some evidence of an interactive subsidy effect of increased phosphorus and velocity on algal productivity. Decomposition increased as a result of increased phosphorus but there was no synergistic interaction of ...


A Comprehensive Study Of Sequential Simulated Moving Bed: Purification Of Xylo-Oligosaccharides And Fructose-Glucose, Yan Li Oct 2019

A Comprehensive Study Of Sequential Simulated Moving Bed: Purification Of Xylo-Oligosaccharides And Fructose-Glucose, Yan Li

Electronic Thesis and Dissertation Repository

Chromatographic separation is a promising alternative for separation and purification of sugars in industry. Simulated moving bed (SMB) technique has been proven as an efficient chromatographic separation method due to its enhanced productivity and purity, reduced solvent consumption, convenient operating control, and improved separation performance for some systems with low resolution and selectivity. The sequential simulated moving bed (SSMB) is a modification of the conventional SMB process, which currently has some applications for sugar separation due to its low solvent consumption. This work mainly investigates the design strategy of the innovative SSMB process and explore its advantages and disadvantages over ...


Methodologies For Metal Functionalization Of Phosphorus Based Photopolymer Networks, Vanessa Béland Oct 2019

Methodologies For Metal Functionalization Of Phosphorus Based Photopolymer Networks, Vanessa Béland

Electronic Thesis and Dissertation Repository

Photopolymer networks with phosphonium cation, alkyl phosphine and olefin functionality were designed, synthesized and functionalized with metals by metathesis, coordination and hydrometallation reactions, respectively. The materials were strategically designed so that the metal functionalization step could be monitored and quantified. In some cases, this involved characterization by IR, NMR, or X-ray spectroscopic techniques, or by comparison to molecular analogues. It was found that by using a bi-functional photopolymer network, the material could be bi-metallized by orthogonal mechanisms. All metallized polymer networks were tested for their suitability as precursors to metal-containing ceramics. The polymers were pyrolyzed, and on analysis it was ...


Excavating Feminist Phenomenology: Lived-Experiences And Wellbeing Of Indigenous Students At Western University, Eva Lynn Cupchik Sep 2019

Excavating Feminist Phenomenology: Lived-Experiences And Wellbeing Of Indigenous Students At Western University, Eva Lynn Cupchik

Electronic Thesis and Dissertation Repository

The Truth and Reconciliation Commission underscores the need to incorporate narrative accounts of Indigenous students’ experiences as part of wide-scale de-colonizing efforts. This dissertation asks; how do Indigenous students experience their identities at Western University? What is at stake for phenomenology, feminist methods, and Indigenous theory, in the post Truth and Reconciliation era?

There is a gap between theories centering on reflective cognition in philosophy and the embodiment of land, prevalent across Indigenous cultures. However, phenomenology can provide a method to facilitate dialogues with discourses outside Eurocentric domains that empathize with marginalized communities’ struggles, through an understanding of location-based knowledge ...


Development Of A Co-Rotating, Fully Intermeshing Twin-Screw Extruder Model For The Extrusion Of Natural Fibre Suspensions, Keller J H George Sep 2019

Development Of A Co-Rotating, Fully Intermeshing Twin-Screw Extruder Model For The Extrusion Of Natural Fibre Suspensions, Keller J H George

Electronic Thesis and Dissertation Repository

Twin-screw extruders are continuous processing devices that have been used in many industries concerned with the processing of multiphase fibrous suspensions, such as the food and pulping industries. While these devices offer great flexibility due to their modularity and customizability, optimization for specific applications can be challenging due to the unavailability of reliable, global models with accurate predictive capabilities. Consequently, this work seeks to eliminate this knowledge gap with the development of a novel global, composite model capable of predicting key process outputs for suspension-processing, phase-separating, co-rotating, fully-intermeshing twin-screw extruders. Creation of the novel global algorithm involved the modification of ...


Design Of Cell-Instructive Biomaterial Scaffolds For Intervertebral Disc Regeneration, Nadia Sharma Sep 2019

Design Of Cell-Instructive Biomaterial Scaffolds For Intervertebral Disc Regeneration, Nadia Sharma

Electronic Thesis and Dissertation Repository

Biomaterials-based therapies targeting the nucleus pulposus (NP) have the potential to promote regeneration and restore mechanical function to the intervertebral disc. This study developed composite hydrogels incorporating decellularized NP (DNP) and assessed its effects on viability, retention and differentiation of U-CH1 cells, an NP progenitor-like cell line. A minimal protocol was developed to decellularize bovine NP that reduced nuclear content while preserving key extracellular matrix components predicted to be favourable for bioactivity. The resulting DNP demonstrated cell-instructive effects, supporting U-CH1 viability and retention within the hydrogels, and promoted the differentiation of the progenitor-like cells towards an NP-like phenotype. These studies ...

Piezo1: Proteins For Mechanotransduction And Integration Of Endothelial Shear Stress & Intravascular Pressure, Juan Garcia Robledo M.D.

Electronic Thesis and Dissertation Repository

Piezo proteins are transmembrane ion channels, specialized in detecting mechanosensitive stimuli and transduce mechanical forces into biochemical signals. Piezo proteins research has helped understand physiological mechanisms, but the integrative role that Piezo1 plays in the regulation of the microvasculature has remained unstudied. Our main objective was to characterize ex vivo microvascular responses to the blockade of Piezo1 mechanotransduction in male (n=29) and female (n=24) Sprague-Dawley (SD) rats. Gracilis arterioles (GA) and middle cerebral arterioles (MCA) were harvested for ex-vivo vessel preparations. After vessel viability confirmation, every vessel was submitted to myogenic and flow challenges under control conditions and ...


Carbon And Nitrogen Dynamics In Plants Grown At Low Co2 Conditions Of The Past, Andre Galvao Duarte Sep 2019

Carbon And Nitrogen Dynamics In Plants Grown At Low Co2 Conditions Of The Past, Andre Galvao Duarte

Electronic Thesis and Dissertation Repository

For most of the recent evolutionary history of plants, atmospheric CO2 concentrations have been far below modern values. However, little is known about how plants grown in a low CO2 environment balance their carbon demand for growth while meeting their requirement for nitrogen acquisition, the establishment of mycorrhizal fungal associations, and the production of defense compounds. Here, I investigated how low CO2 affects Elymus canadensis and Picea mariana by comparing their growth at low and current CO2 concentrations. I found that reduced N availability exacerbated low CO2 effects on growth, and reduced stomatal index and ...


The Impact Of Statistical Learning On Language And Social Competency In Asd And Adhd: Divergent Findings, Kaitlyn M.A Parks Sep 2019

The Impact Of Statistical Learning On Language And Social Competency In Asd And Adhd: Divergent Findings, Kaitlyn M.A Parks

Electronic Thesis and Dissertation Repository

Statistical learning is a process that allows individuals to extract regularities from the environment and plays an important role in language acquisition, speech segmentation, and aspects of social behaviour. Little is known about the contribution of statistical learning impairments on Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) related traits. The current study examined whether impairments in auditory and visual statistical learning are related to ASD and ADHD traits, language, and social competency. Decreased auditory, but not visual statistical learning abilities was related to increased autism traits and visual statistical learning and social competency abilities were mediated by language ...


An Integrated Framework To Assess Compound Flood Risks For Interdependent Critical Infrastructure In A Coastal Environment, Ying Zhang Sep 2019

An Integrated Framework To Assess Compound Flood Risks For Interdependent Critical Infrastructure In A Coastal Environment, Ying Zhang

Electronic Thesis and Dissertation Repository

Compound flooding refers to flood events caused by multiple factors, including marine processes (e.g. storm tides and waves), hydrometeorological signals (e.g. rainfall and river flows) among others. Saint Lucia is a tropical island in eastern Caribbean Sea, which is frequently affected by weather-related extreme events such as tropical storms and the associated risks are exacerbated due to its mountainous topography and high concentrations of infrastructure and human communities close to the coast. At the southern coast of Saint Lucia, significant infrastructures such as Hewanorra International Airport and Vieux Fort Seaport, and human settlements such as towns of Vieux ...


Ceos Don't Wear Afros: Exploring The Justification-Suppression Of Prejudice Against Black Women In The Workplace, Bukun F. Adegbembo Sep 2019

Ceos Don't Wear Afros: Exploring The Justification-Suppression Of Prejudice Against Black Women In The Workplace, Bukun F. Adegbembo

Electronic Thesis and Dissertation Repository

There have been numerous cases where Black women have been disparaged for wearing their natural hair or Afrocentric hairstyles in the workplace. While some have argued that such mistreatment was due to racism, others have stated that it was a case of not adhering to a professional dress code. In line with the justification-suppression model of prejudice, this research investigated whether prejudice against Black women in the workplace is expressed when they wear Afrocentric hairstyles as this allows the bias to be justified under the guise of normative standards of professionalism. Our pilot and main study showed that the Black ...

Who I Am Is Shaped By My Past And Impacts My Future: Exploring Antecedents And Outcomes Of Self-Views Across International, Immigrant, And Canadian Born Undergraduate Students, Anjana Balakrishnan

Electronic Thesis and Dissertation Repository

This dissertation focused on how various self-views variables (self-esteem, self-concept, and self-concept clarity) differ across and within groups of university students, are influenced by internal and external factors, and predict academic and non-academic variables. Key models of self and group perceptions were used in deriving hypotheses (i.e., Shavelson, Hubner & Stanton, 1976; Bosson & Swann Jr, 2009; Stephan, Ybarra, & Morrison, 2009). Across the four studies, self-report questionnaires were used. Studies 1 and 4 were completed online by international, immigrant, and Canadian born students. Studies 2 and 3 examined only international students, involved an experimental manipulation, and were conducted in-lab. The aim of Study 1 was to ...


Registered Nurses’ Perceptions Of The Electronic Canadian Triage And Acuity Scale In A Community Hospital, Andrea De Jong Sep 2019

Registered Nurses’ Perceptions Of The Electronic Canadian Triage And Acuity Scale In A Community Hospital, Andrea De Jong

Electronic Thesis and Dissertation Repository

In 2017, several hospitals in Ontario implemented the Electronic Canadian Triage and Acuity Scale (eCTAS). This new technology affects a critical area of the Emergency Department: triage. There is no research on Registered Nurses’ (RNs) perceptions of eCTAS. A quantitative non-experimental descriptive survey obtained and quantified RN perceptions of eCTAS at a hospital with a 23 bed Emergency Department. The Diffusion of Innovation Theory was used as the theoretical framework to help guide study development. Results indicate both positive and negative perceptions of eCTAS and that younger RNs are more likely to think eCTAS cues them to collect the relevant ...
