title: Performance Measurement and Modeling of BPEL Orchestrations

abstract: Service-oriented architecture (SOA) is a design approach for the development, integration, and maintenance of complex enterprise information systems composed of loosely-coupled services. Runtime services composition introduces performance overheads. Software developers may have difficulties in assessing the performance costs of the final composite product. One objective of this thesis is to design and implement a unified logging facility, which allows us to instrument different layers of a SOA system under study, to automatically collect measurement data and to correlate the separate logs from sub-systems and components into a unified system view. Next, the logging facility is used to collect performance measurement data for a case study system. The measurements are collected separately for the application code and for the underlying service engine. The measured performance data is used for building a Layered Queuing Network model of the case study system and to validate it against measurements.


title: Multi-Robot Exploration Using Potential Games

abstract: In this thesis, we consider exploring a 2-D environment with multiple robots by modelling the problem as a Potential Game rather than using conventional frontier-based dynamic programming algorithms. A potential game is a type of game that results in coordinated behaviours amongst players. This is done by enforcing strict rules for each player in selecting an action from its action set. As part of this game, we define a potential function for the game that is meaningful in terms of achieving the greater objective of exploring a space. Furthermore, an objective function is assigned for each player from this potential function. We then create algorithms for the exploration of obstacle-filled bounded spaces, and demonstrate through simulation how it outperforms uncoordinated algorithms by reducing the time needed to uncover the space.


title: The antioxidant and anti-inflammatory activities of alkylresorcinols from rye bran

abstract: Alkylresorcinols (ARs) are phenolic lipids, found in the bran layer of cereals such as rye. They are natural antioxidants that confer many health benefits. In this study, ARs were extracted from Hazlet rye bran and analyzed for their in vitro antioxidant and anti-inflammatory activities and in vivo antiobesity and antioxidant activities. In vitro studies showed that rye bran ARs have higher antioxidant activity than those from wheat and oat bran. ARs also exhibited anti-inflammatory activity by inhibiting the inflammatory mediator nitric oxide (NO), and gene expression of iNOS and COX-2. ARs did not exhibit antiobesity activity in CF-1 mice fed a 60% high fat (HF) diet but showed in vivo antioxidant activity in the liver using the oxygen radical absorbance capacity (ORAC) assay. In heart tissue, ARs exhibited higher antioxidant activity than the HF control diet, using the ORAC, superoxide dismutase (SOD), and glutathione assays, but results were not significant.


title: Eventide Along the Grand: Homer Watson's Mystical Landscape

abstract: Homer Watson believed that the greatest message a painting could convey was the mystical relationship between man, nature and the spirit world. Imbued with a strong missionary drive, the artist spent his life attempting to express this connection through his landscapes of rural southern Ontario. Building on numerous letters that indicate the artist’s spiritual artistic intention, this thesis takes a socio-historical approach by examining the North American and European social and artistic contexts that led Watson to embrace the spiritist doctrine and envision his art as an exploration of mystical concerns. It will also analyze his paintings in order to identify how those concerns manifested themselves visually through his choice of subject matter, manipulation of nature’s elements, choice of paint colours, and use of impasto.


title: Psychopathic Traits, Substance Use, and Motivation to Change: An Integrative Approach with Juvenile Offenders

abstract: This study investigated the relationship between psychopathy and substance use (SU) and their interaction with motivation to change in predicting risk. Fifty-five adolescent offenders who admitted to using drugs or alcohol at least one time before their index offense were recruited from a south-eastern U.S. detention centre/court. Results indicated that psychopathy was related to a younger age of SU onset and increased severity of SU. However, this relationship appeared to be dependent on the self-report measure of psychopathy used. Psychopathy was only related to increased risk when motivation to change was low, even after controlling for the main effect of SU onset. These results offer initial support that psychopathy, SU, and motivation can be used as part of an integrative approach when working with juvenile offenders. However, more research is needed before such an approach can be used to inform long-term risk predictions or in planning specific treatment plans.


title: A Friendly Demonstration of Force: Pacific Blockade, International Law and State Identity, 1827 to 1921

abstract: This thesis examines the relationship between state identity and pacific blockade, a nineteenth century custom involving the stopping of traffic to a coast without a declaration of war. Drawing on via median constructivism, diplomatic history and international law’s histories, it attempts to explain how pacific blockade emerged despite contradicting contemporary international law, what significance it had for blockading states, and how it could disappear without an explicit rejection. The thesis argues that this practice acquires legitimacy for British decision-makers by performing multiple, conflicting identities in the Ottoman Empire and Latin America. It links pacific blockade to cultural and material hierarchies that legitimized ignoring blockaded states’ interpretations of events. When the institutional and normative context of the practice changes, the thesis argues that pacific blockade loses its legitimacy to states and international law. Thus it provides an example of an exclusive norm disappearing despite its performance of multiple state identities.


title: Empirical Study and Design of Multimodal Ambient Assisted Comfort Services for Senior Citizens

abstract: The growing size of the aging population is becoming a significant issue for many countries, and the United Nation has proposed “aging-in-place” as a solution, which can be implemented with the help from ambient, assisted living system. Many previous works have focused on the emergency and autonomy services, and lack studies on comfort service. The purpose of this study is to conduct an empirical study of using multimodal interfaces in ambient assisted comfort services for senior citizens targeting participants at their home, with a prototype system that supports both traditional and multimodal interaction methods. Scenarios have been defined that include common tasks such as item finding, communication, media access, and setting calendar events. The results showed that all the participants have enjoyed the multimodal interface, and showed better efficiency than traditional interaction method.


title: Testing for a Link Between Personality and Mate-Choice Copying Tendency in the Trinidadian Guppy (Poecilia Reticulata)

abstract: An unexplored area of research is whether personality influences how individuals use social information in a mating context. Here, I experimentally tested, using virgin female Trinidadian guppies (Poecilia reticulata), whether (i) exploratory behaviour and boldness in individual females are repeatable over time, (ii) the exploratory tendency of individuals is correlated with their boldness, (iii) mate-choice copying behaviour is repeatable, and (iv) personality is correlated with an individual’s tendency to mate-choice copy when given the opportunity to do so.  Although both personality scores varied widely among females, neither exploratory or boldness behaviour was significantly repeatable, nor were they correlated with each other. Mate-choice copying behaviour was also not found to be repeatable, and neither personality trait was correlated with an individual’s tendency to mate-choice copy. These results suggest that female guppies were able to adjust their exploratory behaviour and boldness independently of one another.


title: The Rhetoric of Proto-Eugenics in Porfirian Mexico

abstract: This thesis investigates the development of proto-eugenic thought and policy in Porfirian Mexico and how those ideas were important to the Mexican eugenics movement of the twentieth-century.  Proto-eugenics is the name given to the ideas of biological and racial improvement developed by leading Mexican thinkers in the late nineteenth-century, until the Mexican Revolution of 1910.  Proto-eugenic thought was most concerned with eliminating immoral and degenerate traits that could be passed down from parent to child, and encouraging those with prized traits to have children.  Through discussion of writings on criminality and education, this thesis argues that proto-eugenic thought had a large influence on the development of Mexican eugenics in the twentieth-century, and the importance of proto-eugenic thought on nationalism in the Porfiriato.  It is important to understand how proto-eugenic science was created in order to investigate the development of eugenic social policy in the twentieth-century.


title: Bias Estimation in Asymmetric Packet-based Networks

abstract: In the context of the IEEE 1588 Precision Time Protocol (PTP), estimating the delay's bias is a problem that appears in both one-way (using transparent devices) or two-way message exchange mechanisms. For estimating the offset via the two-way message exchange mechanism, it is usually being assumed that the expected value of delays in forward and reverse directions are equal with each other. However this is not a realistic assumption for packet-based wide area networks, where delays in down-link and up-link directions may have a significant difference. In this work we propose a solution to estimate the random delay's bias and improve the synchronization accuracy of IEEE 1588. Our method is easy to implement and is compatible with the current version of the protocol. In addition to the improvement in synchronization accuracy, our method allows us to update the slave clock recursively.


title: The 3-D Imaging of Drill Core for Fracture Mapping

abstract: The Rock Quality Designation (RQD) is a widely used indicator of rock mass strength. This proof of concept research is a step toward the semi-automatic computation of the RQD and is based on 3-D imaging procedures and algorithms to detect fractures in drill core.The images were acquired with a 3-D laser digitizer. Each image file is a point cloud of spatially referenced measurements in Cartesian space. Variations in the z coordinate were used to detect fractures in profile. Natural fractures were distinguished from mechanical breaks by measuring the angle and quantifying the roughness of the fracture trace. The algorithm measured intact lengths of core for the RQD calculation. Established image processing tools were tested on 3-D data. 3-D core models were made.This 3-D approach measures changes in the core surface, not highlights and shadows as with 2-D methods. Limitations arise when there is no detectable change in z.


title: A Comparison of Nonlinear Filters on Mobile Robot Pose Estimation

abstract: Pose estimation for mobile robots attracts a lot of attention in recent years. In order to remove process and measurement noise, a number of filtering approaches are available to use: the extended Kalman filter (EKF), the unscented Kalman filter (UKF), and several variants of the particle filter (PF). This thesis quantitatively explores and compares the performance of the different filtering techniques applied to mobile robot pose estimation. The main criteria compared are the magnitude of the error of pose estimation, the computational complexity, and the robustness of each filter to non-linear/non-Gaussian noise. All filters are applied on both an experimental environment of a differential wheeled robot and a simulated environment of a  three-wheeled robot. The simulation and experimental results indicate that the bootstrap particle filter has the best state estimation accuracy and the most computational cost. The UKF performs better than the EKF and they both have much less computational cost than the particle filter.


title: 'Celebrating Cancer': Young Women Negotiating the Cultural Politics of Survivorship

abstract: This thesis begins with a critical observation that over the past decade, Canadians have witnessed an explosion of discussions in the public sphere about cancer and survivorship, including the celebration of cancer survivors. The proliferation of cancer/survivor discourses circulates expectations about how cancer should be taken on and embodied. There is an urgent need to investigate the effects of such discourses on young women’s (a) access to state and community resources, (b) constructions of health, risk and wellbeing, and (c) personal accounts of their bodies and illness experiences. Drawing on 17 in-depth interviews with young female cancer survivors, this thesis investigates the effects of dominant cancer/survivor discourses on the social and material contexts of young women’s cancer experiences. I argue that young women’s cancer narratives are embedded in discourses of exclusion and responsibilization that actively shape and define what it means to be a ‘good’ survivor/citizen.


title: Study of Multiple Multiagent Reinforcement Learning Algorithms in Grid Games

abstract: This thesis studies multiagent reinforcement learning algorithms and their implementation; In particular the Minimax-Q algorithm, the Nash-Q algorithm and the WOLF-PHC algorithm. We evaluate their ability to reach a Nash equilibrium and their performance during learning in general-sum game environments. We also testtheir performance when playing against each other. We show the problems with implementing the Nash-Q algorithm and the inconvenience of using it in future research. We fully review the Lemke-Howson Algorithm used in the Nash-Q algorithm to find the Nash equilibrium in bimatrix games. We find that the WOLF-PHC is a more adaptable algorithm and it performs better than the others in a general-sum game environment.


title: From Paper to Practice: An Examination of How Public Perception of Disability Influences the Mobilization of Rights, Programs and Services for People with Disabilities

abstract: Policies for Persons with Disabilities are designed with the best of intentions.  They are designed not only to provide these individuals with a level of support, but also to ensure that they are seen as free, independent citizens.   On paper, these designs look to be just what we need – a step in the right direction towards making the concept of disability a thing of the past.  In looking at the everyday mobilization of these programs and policies, we soon see that is not the case.  This is because of old attitudes that still linger around Persons with Disabilities.  To make these policies work, we must first understand and deconstruct our attitudinal barriers.   Upon doing so, we can then suggest new ways to understand disability in the hopes these new options will one day translate into better policies for PwD.


title: In Neoliberal Times: How Non Profit Organizations Are Responding to Housing Need and Affordability in Ottawa

abstract: The central proposition of this thesis is that Canada is experiencing a crisis of affordability in housing that has been exacerbated by neoliberalism. Within neoliberalism, there has been a dramatic change in Canadian housing policy toward an increasing reliance on market forces. A consequence of neoliberalism is a crisis of affordability; there is a shortage of affordable housing for people with low incomes. However, there has also been an advent of new ways to address the housing shortage including some resistance to the neoliberal housing policy and practices promoted by various levels of government. This study examines how five Ottawa based non-profit organizations have been responding to the shortage of affordable housing. The thesis concludes that there are a variety of ways that these organizations have found to successfully innovate to provide some social housing despite neoliberal government housing policy.


title: The Identity Formation Experiences of Second Wave Argentinian Immigrants to Canada

abstract: The thesis explores the processes of identity formation among high-skilled Argentinian immigrants to Canada’s National Capital Region on the basis of a mixed method qualitative research consisting of 14 interviews with Argentinian professionals who migrated to Canada since 1999, participant observation and the analysis of Internet blogs. The thesis examines the identity formation experiences of these immigrants as the “meeting point” of social conditions of migration and personal practices of reacting, reflecting and feeling. Approaching identity as fluid, relational, strategic, positional, and always developing, I argue that the ‘new’ identities that Argentinian immigrants have developed are linked to two main relational processes, namely identification and differentiation. By critically examining the ‘location’ of these immigrants in Canadian society, I suggest the group’s experiences of integration and marginalization are interconnected to these relational processes influencing their notions of who they are in Canada.


title: The Administration of the Non-Insured Health Benefits Dental Care Program and Its Impacts on Nunavut's Inuit Population

abstract: Despite the fact that state-recognized Indigenous persons in Canada are eligible for dental care benefits through the federally-funded Non-Insured Health Benefits (NIHB) program, Nunavut’s Inuit suffer significant oral health disparities relative to the general Canadian population. This thesis explores how the administration of the NIHB program may contribute to the poor oral health outcomes for Nunavut’s Inuit. It proposes that the program as it exists today is financially unsustainable, and is not conducive to public health objectives, identifying three possible areas of reform: the fee-for-service remuneration model, which creates financial incentives for providers to over-treat patients and is not well-suited for Nunavut’s unique environment; the centralized administrative organization, which does not produce policies reflective of Inuit needs; and the provision of service days to communities, which does not follow any discernible formula. I conclude that increased devolution to an Inuit organization may offer solutions to each of these problems.


title: Investigation of CRLH Transmission Lines for Microwave Passive Components

abstract:
For decades, engineers have been searching for ways to reduce the size of electronic circuits while maintaining the efficiency and effectiveness of the circuits. At low frequencies of the microwave band, the size of the conventional transmission line becomes larger, because the wavelength is inversely proportional to the operating frequency; thus, it is needed to reduce the size to agree with the application requirements. Metamaterials are synthetic materials engineered to have a property that is not found in nature. They gain their properties not from their composition, but from their designed structures, and it could be used to reduce sizes of the electronics components.
The increasing demand for metamaterials technology to reduce sizes in electronic circuits, in conjunction with the advances in the Low Temperature Co-fired Ceramic (LTCC) technology, as well as the availability of 300 MHz of bandwidth in the C-band (4.5-5.5 GHz), have created an interest in the development of a metamaterial transmission line which can be used to produce small-size millimeter-wave systems. In this research, the idea of using metamaterial depends on replacing each section of the conventional Right Handed (RH) transmission line, by equivalent Composite Right Left Handed Transmission Line (CRLHTL) implemented using lumped elements.
In this research, the CRLHTL was fabricated on ceramic substrate using 3-metal layers with dielectric constant (ε_r) of 7.1 and substrate thickness of 127 µm. The measurement results were in agreement with the post-layout simulations over the bandwidth of 1-10 GHz. The on-wafer measurements of the transmission line were carried out using Agilent E8361A 10 MHz to 67.0 GHz vector network analyzer, and the EM simulation was performed by using an electromagnetic simulator (Agilent ADS).
As an example of an application, the CRLHTL was implemented in the design of a Branch Line Coupler (BLC). The design of the BLC used a CRLHTL to reduce the physical size of the quadrature wavelength elements of the coupler. The design exercise resulted in a coupler dimension of 5.924mmx5.824mm that is about 22.9% smaller compared to conventional BLC (6.904mm x 6.778mm). Hence, the simulation results of the BLC achieved good performance over the bandwidth of 4.5-5.5 GHz compared to the conventional coupler. This type of coupler is widely used in microwave circuits, such as power combiners and dividers, balanced mixers, image rejection mixers, and balanced amplifiers.


title: Study of Chromogenic Zwitterionic Chromophores

abstract:
To understand the relationship of structure and chromogenic properties of zwitterionic chromophores, dicyanomethane-based (FDCN and MPCT) and tricyanoquinodimethanebased (PpQDM) chromophores were studied. These chromophores are selected based on the design to have different conjugation lengths and thus have the three primary colors: yellow
(FDCN), magenta (MPCT) and cyan (PpQDM). All of the three chromophores exhibited intense absorption in the UV-Vis region with relatively high molar extinction coefficients (ε)
attributed to strong charge transfer (CT) from the negatively charge dicyanomethanide to the positively charged nitrogen in pyridinium.
In this regard, the chromogenic (i.e., color-changing) properties, including solvatochromism, halochromism, and thermo-halochromism of the three chromophores were
studied in solution, polymer gel and solid polymer. Distinctive chromogenic features of  these zwitterionic chromophores were governed by structural factors, including the strength
of the donor and acceptor moieties in addition to the nature of the bridging unit. Thermohalochromic behavior of the chromophores was based on the protonation of the
chromophore by acid and consequently deprotonation by heating. Moreover, the colorchanging process could be reversible and irreversible, depending on the nature of a medium.
Using malononitrile and a polymer gel as a medium, thermo-halochromic process was irreversible, whereas in a suitable polymer host (i.e., PS, PMMA and PS-co-PMMA), these
chromophores showed reversible thermo-halochromic behavior.
Strong charge transfer (CT) of the zwitterionic chromophores in UV-Vis range in addition to their easily CT turned on-off properties eventually led to perform an evaluation
based on their potential application as indirect thermo-indicators. FDCN (as the studied chromophore) demonstrated to be capable of reversibly switching on and off the fluorescence
of the commercial fluorescent dyes under externalstimuli of heat and pH changes.


title: High-Output Voltage Swing in Silicon Broadband Distributed Amplifiers

abstract: The various foundries are now producing CMOS, SiGe and BiCMOS technologies with device speeds that are comparable to some of the III-V technologies. Electro-optical modulators typically are driven with voltages in the range of a few volts to tens of volts, and recent research is producing silicon modulators that require voltages as low as one to two volts. Therefore, a silicon distributed amplifier could be used as a pre-driver, or driver, for the electro-optical modulator if it is able to achieve a minimum one to two volt peak-to-peak swings to drive a silicon electro-optical modulator.The research is an exploration of techniques aimed at improving the large signal output performance of silicon distributed amplifiers for use in fibre optic communication systems. The experimental verification of these techniques involves the design and implementation of several distributed amplifiers in a standard readily available silicon process; ST Microelectronics BiCMOS9 process with eight metal layers and a minimum drawn length of 0.13 microns. A novel distributed amplifier topology has been designed that has artificial transmission lines composed of m-derived filter sections to increase the 3dB passband and a gain stage that increases the bandwidth over that which is available from a single device. The gain stage topology allows the designer to trade the extended bandwidth for the gain necessary to achieve a large output voltage swing. Three distributed amplifiers with bandwidths suitable for 40 gigabit per second data rates have been designed and fabricated and are as follows:•A CMOS single-ended five-stage cascoded fT doubler distributed amplifier producing better than 1V peak-to-peak output voltage swing.•A HBT single-ended three-stage cascoded fT doubler distributed amplifier producing better than 2V peak-to-peak output voltage swing.•A HBT three-stage cascode differential to single-ended distributed amplifier producing better than 2V peak-to-peak output voltage swing.


title: Interactive Effects of a Social Stressor and Interleukin-6 Injection on Anxiety-Related Behaviors and Expression of Pro-Inflammatory Factors in Male CD-1 Mice

abstract: Stressful events induce a range of neurochemical and endocrine changes as part of the brain’s adaptive response to such challenges. If the organism is repeatedly stressed, the development or exacerbation of psychopathologies, such as depression and anxiety, can ensue. A potential role for inflammatory factors in these disorders has emerged. In the present experiment, we investigated whether a challenge with interleukin (IL)-6, a pro-inflammatory cytokine commonly associated with depression, elicits anxiety-related behaviours and alters brain expression of inflammatory factors in CD-1 mice, and whether this differed based on the social stressor backdrop on which the cytokine was applied. The combination of an acute social stressor coupled with IL-6 injection enhanced expression of IL-1β, IL-6, and SOCS3 in a time- and brain region- dependent manner. The current results are consistent with the perspective that stress acts on the JAK/STAT pathway to enhance expression of certain pro-inflammatory factors, possibly leading to pathologies.


title: Role of Akt Signaling and its Downstream Pathways in Wood Frog Freeze Tolerance

abstract: Wood frogs, Rana sylvatica, are one of only a few vertebrate species that survive prolonged whole body freezing during the winter. Multiple adaptations of physiology and biochemistry that support freeze tolerance have been identified including accumulation of extreme levels of glucose as a cryoprotectant and entry into a hypometabolic state that reduces the energy needs of the animal while frozen. To date, the stress responsive signal transduction networks that trigger and regulate these adaptations have received little attention. The current thesis addressed this subject by exploring responses and regulation of a major intracellular signaling pathway (the Akt pathway) that is centrally involved in mediating cellular growth and proliferation responses, typically responding to extracellular insulin signals. Analysis of four organs (liver, kidney, heart and skeletal muscle) showed activation of the Akt pathway in liver but signs of inhibition occurred in other tissues in response to freezing. Activation of Akt-dependent anti-apoptosis mechanisms in liver was also indicated to support cell survival in the frozen, anoxic state. However, analysis of multiple protein components of the cell cycle and TORC1-dependent protein synthesis showed strong suppression of these in all tissues, although with lesser inhibition in liver. This demonstrates the importance of suppressing energy-expensive cell processes under stress conditions. The data show that, during whole body freezing of wood frogs, (1) ATP expensive cellular events such as the cell cycle and protein synthesis were suppressed; (2) liver remains more metabolically active than other tissues tested; and (3) freeze responsive Akt activation in liver does not universally activate all of its downstream pathways but rather selectively triggers specific targets, particularly those important to glucose production as a cryoprotectant and to cell preservation. The thesis also investigated freeze-responsive antioxidant defenses


title: Pore Pressure Parameters and Cyclic Resistance Under Generalized Loading

abstract: A systematic study was undertaken to assess the effects of the magnitude and nature of principal stress rotation on the cyclic resistance of sands. Test results over a range of α_σc and 〖∆α〗_σ indicate that that the weakest cyclic resistance at a given initial α_σc  always correspond to 45° stress rotation, and for a given magnitude of stress rotation (fixed ∆α_σ) the liquefaction resistance generally depends on the magnitude of the torsional shear stress applied on the horizontal plane.  	A limited number of experiments were carried out to investigate the applicability of the Skempton & Henkel pore pressure formulations for generalized 3D initial stress states. Skempton’s pore pressure parameter formulations for isotropic material have been extended to cross anisotropic materials, and it was shown that the principles are applicable even for cross anisotropic materials under generalized initial loading conditions.


title: Thin Client Distributed Simulation of Discrete Event Models

abstract: By combining the new web technologies of HTML5, WebSockets, multi-threading and the WebLVC protocol, a novel technique was developed that allowed the publishing of web based simulation data into a distributed simulation regardless of the FOM specifics. This technique harnessed the power of the thin client to control the state of the RESTful discrete event simulation and automatically populate its simulation results into a distributed simulation.


title: Mental models in discourse production Atypical discourse and the role of event models in the narratives of depressed patients

abstract: A mental model is a partial and subjective cognitive representation of reality (van Dijk, 1985a). Van Dijk’s introduction of the mental model has helped explain the relationship between discourse and cognition. This thesis provides empirical support for and extends Tuen van Dijk’s theory regarding the role of mental models in the production of discourse. It does so by examining the influence of mental models on narratives produced by depressed patients in counseling sessions. Using tools from Systemic Functional Linguistics (Eggins, 2004), the thesis demonstrates how the verb choices can be used to examine the content of mental models, while clausal connections and narrative structure can be used to examine the discursive expression of mental models. Furthermore, local and global atypicalities in patients’ retelling of events suggest possible cognitive processes at work in the conversion of a mental model of an event to spoken narrative.


title: Attachment Style and Obesity: Examination of Eating Behaviours as Mediating Mechanisms in a Community Sample of Ontario Youth

abstract:
Obesity and being overweight are characterized by excess body weight from fat, and are associated with many negative health outcomes. Attachment style has been implicated in the etiology of obesity in youth. The present study examined the relationship between attachment style and body mass index (BMI) in a large community sample of Ontario youth, as well as examined possible mediating mechanisms of this relationship (restrained, emotional, and external eating), while controlling for covariates. Results indicate that insecure attachment was associated with increased BMI, and that this relationship was significantly mediated by restrained eating behaviour. This mediational pathway was moderated by gender; the pathway was stronger for girls than for boys, but was significant for both. These findings suggest that it may be important to take attachment history into account when designing treatment and prevention strategies for obesity in youth.
Keywords: overweight, obesity, attachment, restrained eating


title: Development of Spatial Function in Rats and Associated C-Fos Patterns in the Hippocampal CA1 and CA3 Regions

abstract: The hippocampus shows connectivity-based changes during development. The current work investigated the contribution of performance and cognitive factors in the emergence of spatial function during development. Experiment one showed a sensitive developmental period exists between 16 days old (p16) and p24. Experiment two found impaired performance on spatial learning following NMDAr blockade.  Experiment three explored one-day of water maze training at p16, p18, or p20 and spatial learning was established only at p20. Quantification of c-Fos positive cells in CA3 and CA1 revealed a main effect of age. Lastly, rats were trained on the dry maze at: p16, p17, p18, p19, or p20. Groups p19 and p20 demonstrated spatial learning. Quantification of c-Fos positive cells in CA1 revealed a main effect of age. This suggests that spatial memory mechanisms emerge at p19/p20 independently from performance factors and are based on hippocampal function.


title: Cell Cycle Regulation by Post-Translational and Post-Transcriptional Mechanisms in an Anaerobic Extremist- the Anoxia Tolerant Turtle, Trachemys Scripta Elegans

abstract:
As a model for vertebrate long-term survival in oxygen restricted environments, the red-eared slider turtle (T. s. elegans) can adapt at the biochemical level to deal with hibernation occurring in oxygen-free (anoxic) cold water (<10°C). In this thesis I hypothesized that the mechanisms which suppress ATP-expensive cell cycle activity, would contribute to establishing an hypometabolic state. To explore this possibility, this thesis studied the post-transcriptional and post-translational mechanisms of cell cycle arrest during anoxic stress in the freshwater turtle.
Results indicated a general regulation of critical cell cycle components, in addition to the possible regulation by signaling cascades (Akt/GSK-3β and ATR/Chk2) that are known to regulate G1/G0 phases of the cell cycle. Importantly, there is extensive regulation of Cyclin D1 protein by (1) Akt/GSK-3β signaling, (2) post-translational modification, (3) an AU-rich region, and (4) microRNA-induced translational suppression. This study also identified a phase-specific cell cycle arrest mechanism involving the Rb/E2F DNA-binding complex in both anoxic liver and kidney tissues. A novel DNA-binding complex ELISA technique was able to  identify that both kidney and liver establish an Rb/E2F1 mediated G1 arrest complex by 5 and 20 h anoxia, repectively. By 20 h anoxia, kidney tissue established a reversible state of G0, characterized by the prescence of a p130/E2F4 DNA-bound complex.
Overall, results from this thesis indicate that both kidney and liver enter into a G1 arrest during anoxia. By contrast, the cell cycle in white skeletal muscle was found to be minimally regulated during anoxia and this finding is likely a reflection of its overall post-mitotic nature. Interestingly, kidney established a state of G1 arrest within 5 h anoxia and subsequently transitioned to a sustainable G0 arrest by 20 h anoxia. However, it appears that liver G1 arrest was not established until 20 h anoxia. Future studies will need to explore the regulation of the cell cycle in liver after longer periods of anaerobiosis to determine whether hepatocytes are also able to transition into G0 arrest in a manner similar to kidney tissue.


title: A Changing Sense of Place in Canadian Daily Newspapers: 1894-2005

abstract:
In the modern era, changing perceptions of space and place and external intrusions into local space and culture have been theorized as weakening ties between people and the places they live in. Improvements in transportation and communication have enabled this process. Sociologist Anthony Giddens (1990, 1991) describes the phenomenon as "disembedding" and considers it a hallmark of modernity while geographer Doreen Massey (1994) describes an increasing "disruption" of local spaces occurring over time.
This dissertation provides empirical evidence to support those theories. It examines the changing "sense of place" from 1894 to 2005 in two Canadian metropolitan daily newspapers: the Toronto Star, independent for most of the period under study, and the Ottawa Citizen, owned by a series of national chains since 1897.
The results show a significant decline in local content and the priority it is given in both newspapers over the 112-year study period. Content analysis was used to compare articles from all sections of the newspaper between three time periods: the Victorian (1894-1929), the Professional (1930-1970), and the Corporate (1971-2005).
While the quantity and priority of local news declined significantly in both newspapers after 1970, the decline was much sharper in the chain-owned newspaper. Furthermore, disappearing local content was replaced almost entirely by national stories in both newspapers, with the chain newspaper displaying a much greater increase in national content. The phenomenon replaced many stories that imparted a local sense of place with ones whose sense of place was national.
Three possible reasons for this increase in national content after 1970 — which is the study's major finding— are suggested in the conclusion: the threat of Quebec separatism, rising corporate influence on newspaper priorities, and a gradual process of spatialization that appears to favour the national and the global over the local.
This study relies heavily on Barnhurst and Nerone's (2001) theories about how the form of news structures its messages, and its results support their finding of increased corporate control of news since 1970. Other theories of representation are also examined in an effort to understand how newspapers create and shape a sense of place.


title: Data, infrastructures and geographical imaginations

abstract: The central argument of this dissertation is th at Canadian reality is conditioned by government data and their related infrastructures. Specifically, that Canadian geographical imaginations are strongly influenced by the Atlas of Canada and the Census of Canada. Both are long standing government institutions that inform government decision-making, and are normally considered to be objective and politically neutral. It is argued that they may also not be entirely politically neutral even though they may not be influenced by partisan politics, because social, technical and scientific institutions nuance objectivity. These institutions or infrastructures recede into the background of government operations, and although invisible, they shape how Canadian geography and society are imagined. Such geographical imaginations, it is argued, are important because they have real material and social effects. In particular, this dissertation empirically examines how the Atlas of Canada and the Census of Canada, as knowledge formation objects and as government representations, affect social and material reality and also normalize subjects. It is also demonstrated th at the Ian Hacking dynamic Looping Effect framework of ‘Making Up People’ is not only useful to the human sciences, but is also an effective methodology that geographers can adapt and apply to the study of ‘Making Up Spaces’ and geographical imaginations. His framework was adapted to the study of the six editions of the Atlas of Canada and the Census of Canada between 1871 and 2011. Furthermore, it is shown that the framework also helps structure the critical examination of discourse, in this case, Foucauldian gouvemementalité and the biopower of socio-techno-political systems such as a national atlas and census, which are inextricably embedded in a social, technical and scientific milieu. As objects they both reflect the dominant value system of their society and through daily actions, support the dominance of this value system. While it is people who produce these objects, the infrastructures th at operate in the background have technological momentum th at also influence actions. Based on the work of Bruno Latour, the Atlas and the Canadian census are proven to be inscriptions that are immutable and mobile, and as such, become actors in other settings. Therefore, the Atlas of Canada and the Census of Canada shape and are shaped by geographical imaginations.


title: Integrating culturally relevant learning in Nunavut high schools: student and educator perspectives from Pangnirtung, Nunavut, and Ottawa, Ontario

abstract: The current emphasis in Nunavut high school education, and curriculum development, is to more effectively integrate culturally appropriate learning while also preparing students for their post-graduation goals. Working with students and educators in Pangnirtung, Nunavut and Ottawa, Ontario provided an opportunity to investigate how this goal is manifesting within and outside classroom activities, as well as how this supports student engagement, success, and pride in cultural identity. There are strong joint intentions and efforts being made by Inuit and Qallunaat (non-Inuit) educators alike to work together,involve community members, and bring Inuit Qaujimajatuqangit (IQ - Inuit ways of knowing, being and doing) principles into their school and/or classrooms. However, there are challenges with the practical implementation of an integrated learning approach, resulting in a disconnect between cultural and academic learning. Insights gained through this research aim to provide examples and recommendations to contribute towards ongoing efforts to make improvements for future generations of Inuit.

title: The nature of the body : a cultural history of nudism in postwar Canada

abstract:
Nudism emerged in early twentieth-century Germany as a corrective to the ill effects of industrialization. As recreational nudist clubs took root in Canada after the Second World War, their members engaged with contemporary concerns about mental health, juvenile delinquency, and sexual deviance. They promoted nudism as familyfriendly and as a means to realize the widely shared parenting objective of creating psychologically healthy, well-adjusted citizens.
Nudism in postwar Canada was an embodied practice intended to re-make the mind. Canadian nudism both challenged and reinforced postwar social norms. Committed to dissociating nudity from sexuality, nudist clubs created space for men, women, and children to socialize in the nude. Nudists argued that the acts of going nude and looking at the nude bodies of others satisfied natural curiosity and loosened the hold of social taboos. Despite their transgression of taboos around nudity, nudists sought social respectability. In particular, they embraced the hetero-normativity of mainstream Canadian society, and argued that their practice strengthened rather than undermined marriage and family life.
This dissertation explores local club operations, nudist representations of the body through photography and pageants, and tensions surrounding new forms of social nudism that emerged around 1970. It situates the body as a site of both social regulation and resistance, and explores the negotiations of a group of otherwise ordinary Canadians as they grappled with the nature of the body in modern life.

title: Systematics and molecular pathogenesis of oomycetes with emphasis on flagellar genes

abstract: Oomycetes are ubiquitous fungus-like protists which include serious pathogens of agricultural, horticultural, and aquatic commodities. Proper identification to the species level is a critical first step in any investigation of oomycetes, and the use of DNA for oomycete species identification is well established, but DNA barcoding with cytochrome c oxidase (COI) is a relatively new and potentially useful approach that had yet to be assessed over a significant sample of oomycete genera. DNA sequencing of COI from 1205 isolates representing 23 genera and a comparison to internal transcribed spacer (ITS) sequences from the same isolates showed that COI-based identification and the dataset generated are a valuable addition to the currently available oomycete taxonomy resources. Due to the fact that studies o f oomycete evolution and taxonomy have traditionally been heavily reliant on ribosomal RNA and mitochondrial cytochrome oxidase sequencing to infer species boundaries and higher level phylogenetic relationships, a new approach to oomycete molecular systematics was undertaken using two single-copy protein-coding flagellar genes, PF16 and OCM1, showing their utility in species delimitation and in phylogenetic reconstruction o f oomycete evolution. This approach also demonstrates, a recently proposed codon substitution-based phylogenetic method. Using the codon model, the phylogenetic relationships inferred by flagellar genes are largely in agreement with the current views of oomycete evolution, whereas nucleotide and amino acid models failed to reconstruct monophyly in several clades. Interesting parallels exist between the molecular evolution of flagellar genes and zoospore ontology, supporting the tree obtained using the codon model. Sequencing of OCM 1 in particular revealed high variability among oomycetes and indicated a potential role of this protein in host-interaction of zoospores. A hypothesized role of OCM1 in host recognition, possibly through interaction with host C-type lectin was tested, and although the role of OCM1 was not confirmed, plant C-type lectin was shown to contribute to susceptibility of Arabidopsis seedlings to Pythium zoospores. This is a novel and important finding which helps to understand the unknown function of C-type lectin in plants. As a whole, this thesis contributes new resources and knowledge to the study of oomycetes, molecular evolution, and plant pathology.

title: Context-aware smart home monitoring through the analysis of pressure sequences

abstract:
As the senior population in Canada ages, the need for costly healthcare monitoring increases and the expected workloads of many of the hospitals and nursing care facilities across the country begin to exceed the personnel available. There is therefore an increasing interest in smart home technology which can provide automated monitoring of the health and well-being of seniors. This thesis presents the design of a smart home system which uses unobtrusive pressure sensing and incorporates context-awareness in the monitoring of an occupant's functional mobility. To validate the design, clinical trials were conducted with both healthy adults and mobility-impaired seniors, thereby simulating the decline in an occupant's mobility over an extended period of time due to underlying conditions.
The proposed system design includes several algorithms to extract features from pressure sequences recorded during sit-to-stand (SiSt) transfers. The first was designed to detect and characterize regions of interest from pressure images recorded from sensors placed under a bed mattress. The algorithm allowed the observation of mobility-impaired cases as well as the automated classification of symmetry with an accuracy of 93%. An algorithm was also designed to analyze the sagittal center of pressure trajectory during SiSt transfers from a bed. This allowed the extraction of significant clinical features and enabled the automated detection of mobility impairment with an accuracy of 92%. A third algorithm measured the duration of the SiSt transfer using both bed and floor pressure sequences. The durations displayed significant differences between the healthy (2.31 s for young adults, 2.88 s for seniors) and mobility-impaired (3.57 s for post-stroke, 5.35 s for post-hip-fracture) participant groups. These results compared closely to those found in recently published literature using more obtrusive methods of data collection.
Various sources of context-awareness were introduced into the monitoring system design including context from pressure sensors embedded in the grab bars of a lavatory commode. A simulated context-aware environment was designed to demonstrate the function of the monitoring system using sequences collected from participants during the various clinical trials. The environment illustrated the effects of incorporating context-awareness through simulated scenarios of occupant behaviour and samples of corrected classification.

title: Efficient subband structures for acoustic echo cancellation in nonstationary and nonlinear environments

abstract:
The focus of this thesis is the development of computationally efficient adaptive filter structures capable of operating in nonstationary and nonlinear environments, with application to the acoustic echo cancellation (AEC) problem in hands-free communication systems. The specific nonstationary environments considered are changing conditions in the acoustic environment resulting from the movement of people and objects, as well as changing operating conditions of hands-free devices. The particular nonlinear environments arise from the harmonic loudspeaker distortion in hands-free devices.
The linear and nonlinear echo path components for several hands-free systems are identified based on experimentally measured data collected under the nonstationary and nonlinear environments previously outlined. The subsequent analysis revealed that these components and their fluctuations are confined to specific time and frequency regions, which provides insight for achieving computational complexity reduction in echo cancellers (ECs) operating in these environments.
An oversampled subband EC structure based on a generalized gradient proportionate step size adaptive algorithm is proposed for AEC in fast changing environments. The structure's enhanced echo cancellation performance compared to fullband ECs is verified through computer simulations. Improvements in echo return loss enhancement (ERLE) of up to 7 decibels (dBs) are realized compared to an equivalent fullband structure, based on measured data from hands-free systems under changing conditions, while requiring decreased complexity.
AEC in the presence of nonlinear loudspeaker distortion is addressed by developing an oversampled subband EC structure based on adaptive Volterra filters. Experimental results validate the structure's equivalent nonlinear echo attenuation ability compared to its fullband counterpart, while requiring much lower complexity. Compared to a linear EC, the proposed structure achieves up to 7 dB higher ERLE with a similar computational cost.
For AEC in changing nonlinear environments, an oversampled subband EC structure with adaptive Volterra filters based on a generalized gradient proportionate variable step size adaptive algorithm is proposed. The structure improves echo cancellation performance by up to 5 dB higher ERLE with significantly reduced computational expense compared to an equivalent fullband structure, based on experimental results with measured hands-free system data.

title: Co-channel speech separation using state-space reconstruction and sinusoidal modelling

abstract:
This thesis deals with the separation of mixed speech signals from a single acquisition channel; a problem that is commonly referred to as co-channel speech separation. The goal of the thesis is to present some contributions towards the design and implementation of a robust and enhanced co-channel speech separation system.
The phenomenon of co-channel speech commonly occurs due to the combination of speech signals from simultaneous and independent sources into one signal at the receiving microphone, or when two speech signals are transmitted simultaneously over a single channel. An efficient co-channel speech separation system is an important front-end component in many applications such as Automatic Speech Recognition (ASR), Speaker Identification (SID), and hearing aids.
The separation process of co-channel speech consists, mainly, of three stages: Analysis, Separation, and Reconstruction. The central separation stage represents the heart of the system in which the target speech is separated from the interfering speech. At the front, since the separation process works on one segment of co-channel speech at a time, a mean must be found in the analysis stage to accurately classify each segment into single or multi-speaker before separation. Precise estimation of each speaker's speech model parameters is another important task in the analysis stage. The speech signal of the desired speaker is finally synthesized from its estimated parameters in the reconstruction stage. In order to have a reliable overall speech separation system, improvements need to be achieved in all three stages.
This thesis introduces a classification algorithm that is capable of determining the voicing-state of co-channel speech. The algorithm uses some features of the reconstructed state-space of the speech data as a measure to identify the three voicingstates of co-channel speech; Unvoiced/Unvoiced (U/U), Voiced/Unvoiced (V/U), and Voiced/Voiced (V/V). The proposed method requires neither a priori information nor speech training data. Nonetheless, simulation results show enhanced performance in identifying the three voicing-states at different target-to-interference ratio (TIR) values as well as at different levels of background noise compared to other existing techniques.
A time-domain method to precisely estimate the sinusoidal model parameters of co-channel speech is also presented. The method does not require the calculation of the discrete Fourier transform nor the multiplication by a window function which both degrade the estimate of the sinusoidal model parameters. The method incorporates a least-squares estimator and an adaptive technique to model and separate the cochannel speech into its individual speakers. The application of this method on speech data demonstrates the effectiveness of this method in separating co-channel speech signals with different TIRs.

title: Biosensor-based alternatives for food safety analysis

abstract:
The objective of this thesis was to investigate the feasibility and potential of using specific biosensor-based methods - electronic nose (e-nose) and Raman spectroscopy - as alternatives to conventional methods for food safety analysis. The principal shortcoming associated with conventional methods is the length of time required for an unequivocal result (5-7 days). Measurement systems were designed by taking raw sensor responses from off-the-shelf biosensor instruments, extracting meaningful features from these (using appropriately selected signal processing algorithms), and performing pattern classification (and validation) to assess their effectiveness in identifying the contaminant.
For bacteria (E. coli and Listeria) hosted in nutrient broth, e-nose based systems using metal oxide sensors (MOS) and fingerprint mass spectrometry were used to discriminate between bacteria at different concentrations with discrimination evident at levels down to 106 cells/mL.The capacity of these systems to identify bacteria at lower concentrations was hindered by a time-varying drift inherent to the nutrient broth.
Using individual bacterial colonies, a MOS-based e-nose measurement system was able to discriminate between four bacteria types (two E. coli strains, Listeria and Enterococcus). Multiple consecutive e-nose responses were employed to achieve classification accuracies exceeding 90%. A surface-enhanced Raman spectroscopy based measurement system employing wavelet-based pre-processing and feature extraction stages was developed to discriminate between species of Listeria, yielding classification accuracies of over 90%.
Motivated by the potential to incorporate e-nose technology in a smart home environment, a MOS-based system was used to measure food spoilage. The e-nose sensor responses demonstrated smooth trajectories in both original and dimension-reduced feature spaces and the degree of spoilage (as measured by sample age) were found to correlate with extracted features. In order to guide future research in this area, a framework for incorporating odour sensing into a smart home for identification of problems and activities of daily living is proposed.
Because the sample types used in this thesis are available relatively early in the inspection process, the performance of these methods justifies further work to assess their potential in a pre-screening capacity. The use of confidence measures is also explored to identify which samples might be classified with confidence with the proposed methods.

title: Context-aware algorithms for sleep apnea monitoring and sensor acceptance using unobtrusive pressure sensors arrays

abstract:
As older adults require more health care services, solutions are needed to shift the delivery of services from hospitals and nursing facilities to clients' homes. Many sleep disorders are serious enough to interfere with activities of daily living and have significant health and social consequences. Polysomnography, while invasive and expensive, provides a quantitative assessment of sleep quality by recording physiological variables with the use of multiple face and body electrodes.
The goal of this thesis is to develop unobtrusive sleep monitoring technologies to facilitate non-invasive and home-based biomedical and preventive monitoring. This thesis presents multiple algorithms for use with unobtrusive pressure sensors in sleep monitoring. The algorithms for rollover detection, central apnea detection, sensor fusion, and delay profiling were validated with controlled experiments or with data acquired using polysomnography and unobtrusive sensors simultaneously. These algorithms incorporate context from patient-driven and data-driven sources to optimize parameters and screen patients. This thesis also presents a model of sensor acceptance as a tradeoff between privacy and autonomy.
Algorithms were developed to address the importance of central apnea and the effect of positional sleeping on apnea severity. Using data collected from the West Ottawa Sleep Center, an algorithm classified central apnea events with a sensitivity >87%, specificity >99%, and a Cohen's kappa value of 0.875, which compares well with the current literature. The decision tree created using controlled experiment data identified rollovers with a sensitivity >81% and 100% specificity, which compliments existing static position detection schemes. A hypothesis was put forth that most older adults would likely not accept video surveillance in any situation, however frail older adults might be willing to "trade in their privacy" if it meant preventing nursing home placement. The hypothesis was accepted following a literature review of smart home monitoring sensor preferences.
