An Interpretation Of Relativistic Spin Entanglement Using Geometric Algebra, Crystal-Ann Mckenzie
An Interpretation Of Relativistic Spin Entanglement Using Geometric Algebra, Crystal-Ann Mckenzie
Electronic Theses and Dissertations
Entangled states are often given as one of the most bizarre examples of “weirdness” described as inherent to quantum mechanics. The present work reinterprets entanglement as not being a property of states at all, but rather as a relationship between the reference frames in which the states reside, which proposes to reduce “weirdness” of interpretation. Using the geometric Algebra of Physical Space, it has been shown that a classical form of the Dirac equation can be satisfied by any eigenspinor, which is a Lorentz transformation operator describing the relative velocity and relative orientation of the rest frame of a system …
Do The Words People Write Capture Their Process Of Change, Orrin-Porter Morrison
Do The Words People Write Capture Their Process Of Change, Orrin-Porter Morrison
Electronic Theses and Dissertations
The current study examined the use of commonly used word categories, less commonly used word categories, and change in word use over time in an expressive writing task. A sample of 250 undergraduate students from an archival study who were still experiencing unresolved feelings wrote about a targeted distressing experience for 15 minutes on each of three consecutive days. Narratives were analyzed using the Linguistic Inquiry and Word Count Program (LIWC). Results showed that six word categories predicted change in outcome, namely first-person singular pronouns, words related to causation, inhibition, certainty, past-tense verbs, and word count. Words related to cognitive …

The study builds on my two years of participation as a graduate assistant in the Reciprocal Learning Program, which is part of the SSHRC Partnership Grant Project between Canada and China. This study focuses on five participants’ personal and professional understanding of cross-cultural knowledge. Based on Connelly and Clandinin’s (1988) narrative inquiry, this study finds some changes from the participants’ …
Stochastic Goal Programming And A Metaheuristic For Scheduling Of Operating Rooms, Justin William Britt
Stochastic Goal Programming And A Metaheuristic For Scheduling Of Operating Rooms, Justin William Britt
Electronic Theses and Dissertations
Health care systems in Canada provide benefits to patients but have issues with costs and wait lists. Long wait lists negatively affect patients’ welfares. This in turn can increase costs because conditions can develop into more complicated ones over time. Operating rooms in a hospital are responsible for a significant portion of both costs and benefits; therefore, finding ways to use them more efficiently can reduce both the waste of tax dollars and the lengths of wait lists and can improve patients’ welfares. In this research, a stochastic weighted goal programming model is proposed to perform elective surgery scheduling under …
Normative Democratic Deliberation And The Role Of Argumentation In The Canadian Mandatory Minimum Sentence Debate, Caitlin Sivell
Normative Democratic Deliberation And The Role Of Argumentation In The Canadian Mandatory Minimum Sentence Debate, Caitlin Sivell
Electronic Theses and Dissertations
This paper explores the role of argumentation within the debates on Bill C-10, the Safe Streets and Communities Act, that came into force in 2012. Through examining Hansard transcripts, this paper aims to investigate how argumentation on mandatory minimums was utilized in this political decision making setting to legitimize and accomplish this policy initiative. I draw upon the concepts of normative democratic deliberation, new right ideology and the punitive turn to explore the Harper government’s use of argumentation strategies and discuss their implications for the Canadian political process and the current direction of the administration of justice in Canada. This …
Heavy P-Block Analogues Of Dithiazolyl Radicals, Thao Thi Phuong Tran
Heavy P-Block Analogues Of Dithiazolyl Radicals, Thao Thi Phuong Tran
Electronic Theses and Dissertations
This thesis commences with an introduction to the chemistry and materials properties of dithiazolyl radicals and a review of previous research on the isolobal heterocyclic phosphorus-containing derivatives, particularly dithiaphospholes and diazaphospholes. P-chloro-1,3,2-benzo-dithiaphospholes were prepared from the condensation of PCl3 and 1,2-benzodithiols in good yield. Reduction afforded 2c,2e- P-P s-bonded dimers containing a formal PII oxidation state which were characterised by X-ray diffraction. Re-oxidation generates the crystallographically characterised Phalogeno- 1,3,2-benzo-dithiaphospholes. The synthesis and structural characterisation of the isolobal P-chloro-1,3,2-benzodiazaphospholes, C6H4(NR)2PCl (R = H, Me, Et, COMe, COOMe) is described. The outcome of attempted reductive coupling was found to be sensitive to …
Constrained Optimization For Bottleneck Peak Hour Pricing, Da Xu
Constrained Optimization For Bottleneck Peak Hour Pricing, Da Xu
Electronic Theses and Dissertations
We study the morning commute problem with a peak period flat toll, where the toll has a maximum acceptable toll level and a maximum acceptable length of tolling period. Under such a constrained optimization setup, we investigate the system cost minimization problem. A tolling scheme is determined by the toll starting time, the toll ending time, and the toll level. The toll starting time and ending time are set before and after the common work start time, respectively. We find out that, under the toll window length constraint only, a balanced toll window design is always optimal, where “balanced” means …
Towards A New Model Of Semantic Processing: Task-Specific Effects Of Concreteness And Semantic Neighbourhood Density In Visual Word Recognition, Ashley Danguecan
Towards A New Model Of Semantic Processing: Task-Specific Effects Of Concreteness And Semantic Neighbourhood Density In Visual Word Recognition, Ashley Danguecan
Electronic Theses and Dissertations
According to data from three tasks, Danguecan & Buchanan (2014) demonstrated that semantic neighbourhood density (SND; Buchanan, Westbury, & Burgess, 2001) interacts with concreteness to influence visual word recognition response times (RTs). Importantly, these data suggest that the behavioural effects of these semantic variables are differentially impacted by task demands. The goal of the present study was to more precisely chart the flexibility of semantic processing by comparing recognition RTs of words (varying in concreteness and SND) across seven tasks with different explicit semantic requirements. The data show that linguistic associative information is particularly critical for abstract as compared to …
From Participation To Differentiation: A Framework For Re-Designing A Socio-Technical System, Victoria Townsend
From Participation To Differentiation: A Framework For Re-Designing A Socio-Technical System, Victoria Townsend
Electronic Theses and Dissertations
Engineers are responsible for re-designing socio-technical systems (STSs). At the same time, the current literature on engineering re-design methodology is predominantly oriented towards technical artefacts. This methodology is not directly transferable to STSs, since STSs differ in the role of workers operating the system in collective activity. Accordingly, the central question of this dissertation is: How can engaging STS operators as participants in re-designing an assembly production system develop an approach for re-designing STSs that operationalizes human value and potential? To this aim, this dissertation develops a framework for re-designing a STS. This framework is developed with design research methodology …
Risk And Resilience In Emerging Adults With Childhood Parentification, Kristen Williams
Risk And Resilience In Emerging Adults With Childhood Parentification, Kristen Williams
Electronic Theses and Dissertations
Childhood parentification, an adult-child role reversal in which a child provides physical and/or emotional care for a parent, has been associated with both adaptive and maladaptive outcomes in emerging adulthood (Hooper, 2007b). The current three-part investigation (quantitative, written narrative, interview) used quantitative and qualitative methods to explore adjustment in emerging adulthood following childhood parentification experiences and sought to identify factors that may influence parentification outcomes. In total, data from 205 participants were analyzed in the quantitative portion of the study, with 181 participants providing written narrative responses and 10 individuals participating in a follow-up interview. Results from quantitative and qualitative …
Properties And Applications Of Basalt Fibre Reinforced Concrete, John-Sebastian Branston
Properties And Applications Of Basalt Fibre Reinforced Concrete, John-Sebastian Branston
Electronic Theses and Dissertations
Basalt fibre has gained popularity in concrete reinforcing applications due to its excellent mechanical properties and an environmentally friendly manufacturing process. Research work presented in this thesis was undertaken to better understand potential applications of three different types of basalt fibre construction: filament and bundle dispersion fibres, and basalt fibre reinforced polymer bars (minibars). Mechanical performance was evaluated by measuring the effect of the fibres on the pre- and post-cracking behaviour of concrete, and by investigating how the fibre-concrete interfacial properties influenced that behaviour. Durability was evaluated by measuring the effect of the fibres on unrestrained plastic shrinkage, and their …
Academic Entitlement, Student Motivation, And Academic Outcomes, Marc Philip Frey
Academic Entitlement, Student Motivation, And Academic Outcomes, Marc Philip Frey
Electronic Theses and Dissertations
There has been a recent influx of preliminary research examining Academic Entitlement (AE) and the corresponding implications. However, little is known about the antecedents and outcomes of entitled attitudes on the part of students. Initial findings suggest that those high in AE are more extrinsically motivated and have an external locus of control (Greenberger, Lessard, Chen, & Farruggia, 2008). Self-Determination Theory (SDT) provides a theoretical basis for understanding this constellation of characteristics and may prove useful in curbing AE. According to SDT, diminished levels of intrinsic motivation for tasks and increased non-self-determined motivation results in decreased task persistence, enjoyment in …
Dominance In Multi-Population Cultural Algorithms, Santosh Upadhyayula
Dominance In Multi-Population Cultural Algorithms, Santosh Upadhyayula
Electronic Theses and Dissertations
We propose a new approach that can be used for solving the knowledge migration issue in multi-population cultural algorithms (MPCA). In this study we introduce a new method to enable the migration of individuals from one population to another using the concept of complete dominance applied to MPCA. The MPCA’s artificial population comprises of agents that belong to a certain sub-population. In this work we create a dominance multi population cultural algorithm (D-MPCA) with a network of populations that implements a dominance strategy. We hypothesize that the evolutionary advantage of dominance can help improve the performance of MPCA in general …

The Male Media Ideal: Effect Of Body Conceptualization And Knowledge Of Digital Alteration On Older Adolescent And College-Aged Men, Katherine Krawiec
The Male Media Ideal: Effect Of Body Conceptualization And Knowledge Of Digital Alteration On Older Adolescent And College-Aged Men, Katherine Krawiec
Electronic Theses and Dissertations
In two studies, the effects of exposure to media images that differed in body conceptualization and in disclaimer type on men’s self-evaluations, negative affect, and muscle-building behaviour were examined. State and trait social comparison were included as moderators. For Study 1, it was hypothesized that men would report greater muscle dissatisfaction and negative affect, lower physical condition esteem, and engage in less muscle-building behaviour following the viewing of body-as-object images than those who viewed body-as-process images. These effects would be more pronounced for men who engaged in greater state comparison. Body conceptualization was manipulated by showing 101 men images that …
Using Heritage In Multi-Population Evolutionary Algorithms, Andrew William Hlynka
Using Heritage In Multi-Population Evolutionary Algorithms, Andrew William Hlynka
Electronic Theses and Dissertations
Multi-Population Cultural Algorithms (MPCA) define a set of individuals that can be categorized as belonging to one of a set of populations. Not only reserved for Cultural Algorithms, the concept of Multi-Populations has been used in evolutionary algorithms to explore different search spaces or search for different goals simultaneously, with the capability of sharing knowledge with each other. The populations themselves can define specific goals or knowledge to use in the context of the problem. One limitation of MPCA is that an individual can only belong to one population at a time, which can restrict the potential and realism of …
Analysis And Improvement Of Aerodynamic Performance Of Straight Bladed Vertical Axis Wind Turbines, Mojtaba Ahmadi-Baloutaki
Analysis And Improvement Of Aerodynamic Performance Of Straight Bladed Vertical Axis Wind Turbines, Mojtaba Ahmadi-Baloutaki
Electronic Theses and Dissertations
Vertical axis wind turbines (VAWTs) with straight blades are attractive for their relatively simple structure and aerodynamic performance. Their commercialization, however, still encounters many challenges. A series of studies were conducted in the current research to improve the VAWTs design and enhance their aerodynamic performance. First, an efficient design methodology built on an existing analytical approach is presented to formulate the design parameters influencing a straight bladed-VAWT (SB-VAWT) aerodynamic performance and determine the optimal range of these parameters for prototype construction. This work was followed by a series of studies to collectively investigate the role of external turbulence on the …
Examining The Influence Of Recovery Strategy And Rest Interval Length On Performance In Trained And Untrained Individuals, Neil Ryan Pettit
Examining The Influence Of Recovery Strategy And Rest Interval Length On Performance In Trained And Untrained Individuals, Neil Ryan Pettit
Electronic Theses and Dissertations
The purpose was to investigate the influence of recovery strategy (active vs. passive) and rest interval length (60 vs. 120 seconds) on performance after two high intensity interval training (HIIT) workouts with a battling rope (BR; ten 30 second intervals). Trained participants (9 male/11 female) completed a 4 week BR HIIT program while untrained participants (10 male/10 female) were new to BR protocol. There were no significant differences between pre- and post-test push up or sit up performance as a result of recovery strategy or rest interval length for both workouts. However, blood lactate varied by gender and training status …
Formation Of The Neoarchean Bad Vermilion Lake Anorthosite Complex And Spatially Associated Granitic Rocks At A Convergent Plate Margin, Superior Province, Western Ontario, Canada, Shuda Zhou
Electronic Theses and Dissertations
The Neoarchean Bad Vermilion Lake Anorthosite Complex (BVLA Complex) is one of the most well-exposed, anorthosite-bearing, Archean layered intrusions in the Superior Province. Zircons from the intruding granitic rocks have yielded a 207Pb/206Pb age of 2716 ± 18 Ma, constraining the minimum intrusion age of the complex. Mantle-like oxygen isotope signatures of the anorthosites and trace element patterns in the various units of the BVLA Complex suggest that they were derived from melting of a shallow source in a subarc mantle wedge. The existence of primary calcic igneous plagioclase, coherent Nb negative anomalies, and geochemical similarities between gabbros from the …
Vocal And Visual Communication In An Explosively Breeding Neotropical Toad, Nicolas Rehberg-Besler
Vocal And Visual Communication In An Explosively Breeding Neotropical Toad, Nicolas Rehberg-Besler
Electronic Theses and Dissertations
Frogs and toads use both acoustic and visual signals to communicate within their noisy, competitive breeding aggregations. In this thesis, I studied acoustic and visual signals in the Neotropical yellow toad, Incilius luetkenii, in Costa Rica. I provide the first quantitative description of this species’ vocal behaviour, and I demonstrate that the spectral properties of male calls are correlated with body size; therefore, male calls may be used in size assessment. I experimentally demonstrate that chorus transmission distance is enhanced by the number of concurrently calling toads as well as the pitch of their calls; therefore choruses may attract more …

Experimental Study On Vibration Mitigation Of Bridge Stay Cables Using Cross-Ties And Hybrid System, Gnanasekaran Sandanam
Experimental Study On Vibration Mitigation Of Bridge Stay Cables Using Cross-Ties And Hybrid System, Gnanasekaran Sandanam
Electronic Theses and Dissertations
Controlling excessive vibrations of stay cables on cable-stayed bridges is important to minimize the fatigue failure and damage at the cable anchorages. Using cross-ties to connect a vulnerable cable with its neighbors to form a cable network and installing external damper to a cable have been widely used in field. More recently, the idea of adding damper to an existing network to form a hybrid system was also proposed. Though the stiffening effect of the cross-tie solution are widely studied by numerous researchers, the damping property of a network has rarely been investigated. Also, the available studies on the hybrid …
Coercive Control And Physical Violence At The Onset Of Dating Relationships: A Prospective Longitudinal Study, Amanda Rachel Levine
Coercive Control And Physical Violence At The Onset Of Dating Relationships: A Prospective Longitudinal Study, Amanda Rachel Levine
Electronic Theses and Dissertations
Intimate partner violence (IPV) has been suggested as a consequence of coercive control (CC), a pattern of demands placed on a romantic partner, threats about what will occur if the demands are not met (e.g., IPV), and surveillance to ensure that demands have been met (Dutton & Goodman, 2005). This hypothesis has yet to be examined among dating couples, and little is known about how CC and physical violence arise in dating relationships. The current study had three main objectives: (a) to determine the way in which CC and IPV change over time in newly established dating relationships, (b) to …
Pre-Service Educational Assistants’ Attitudes Toward Inclusion, John Freer
Pre-Service Educational Assistants’ Attitudes Toward Inclusion, John Freer
Electronic Theses and Dissertations
In recent years, educational assistants have taken on an integral role in special education. They often work with the most challenging and vulnerable student population. To prepare EAs, some of Ontario’s publicly funded colleges have developed pre-service programs. In Ontario, the number of students receiving special education services in K-12 is increasing, and policy trends are advocating for educational inclusion. Literature has suggested that educators’ attitudes toward educational inclusion may impact the extent to which inclusive strategies are implemented. Despite the importance of EAs in the special education team, very few studies have investigated their attitudes toward inclusion. This study …

Ferritic Nitrocarburizing Of Plain Carbon Steels, Madhavan Manivannan
Ferritic Nitrocarburizing Of Plain Carbon Steels, Madhavan Manivannan
Electronic Theses and Dissertations
Nitrocarburizing is a case hardening process which improves the hardness and wear resistance of a component, but results in geometric distortions. Torque converter pistons (automotive component) and Navy C-ring specimens (measuring tool) made from SAE 1010 plain carbon steel were used for the distortion analysis. Navy C-rings are generally used for studying the dimensional changes of a material before analyzing the dimensional changes of the actual component. Navy C-rings of varying thicknesses were used to analyze the effect of distortions with the change in thickness. Finite element simulations of Navy C-rings and torque converter pistons were developed to study the …

The present investigation looked at students’ reading achievement within the context of the Peer Assisted Learning Strategies (PALS) intervention. It consisted of three separate studies, all of which are related to reading achievement and intervention during the early years of school. The purpose of Study One was to determine whether students who are identified with reading disabilities via psychological assessment report make improvements over the school year subsequent to the implementation of this report. It was hypothesized that when teachers have access to psychological assessment reports, they will better understand their students’ individual learning needs and that this will translate …
A Mixed Methods Examination Of The Influence Of Social Culture On Perceptions Of Culturally Adaptive Behaviours And Trustworthiness In Work Settings, Iris Yu-Yi Lin
Electronic Theses and Dissertations
A mixed-methods approach was used to assess the role of trustworthiness in cross-cultural business partnerships. In Study One, qualitative responses from 100 undergraduate students (50 Canadian, 50 Taiwanese) were analyzed to identify cultural similarities and differences in their perceptions of a trustworthy person, employee, and supervisor/employer. Respondents from both countries used descriptors that fit the ability, benevolence, and integrity framework to describe trustworthy individuals. However, comparison between countries and between targets (i.e., person, employee, supervisor/employer) revealed differences in the frequency with which certain types of descriptors were used. Additionally, dimensions of trustworthiness not included in the ability, benevolence, and integrity …
