description: This thesis examines news representations of Canadian, American and Australian military personnel involved in military 'sex scandals'. I explore what the representations of military personnel involved in well-publicized sex scandals reveal about scripts of soldiering and militarized masculinities. Despite a history of systemic violence in the military, I ask how and why the systemic nature of militarized masculinities are able to remain invisible, driving representations to focus on the ‘bad’ behaviour of individuals? By engaging with feminist scholarship in International Relations, I present the longstanding culture of misogyny, racism, homophobia and ableism in the Canadian, American and Australian militaries, focusing on the ways in which militarized masculinities are guided by these violent structures, and fundamental to the military's creation of soldiers. My dissertation uses the tools of critical discourse analysis to unpack the ways blame is individualised in cases of sexual and racist violence involving military personnel, while the military’s ableism, rape culture and imperial militarized masculinities are commonly naturalized or celebrated without regard for how they are fundamentally violent. My thesis presents an intersectional feminist project that intervenes in emerging questions in the field of transnational disability studies, tracing how militarism, hegemonic militarized masculinities and imperial soldiering (re)produce categories of ability and disability.
Towards living sustainably: a study of Australian consumers' sustainable behaviours and intentions
Creators: name: Rex, Judith
Publisher: name: Swinburne
Year: 2024

description: Recognising the need to increase society’s concern for the environment and natural resources, governments and organisations have moved towards developing and adopting policies to promote the uptake of sustainable behaviours, such as recycling and reducing the reliance on non-renewable energy sources. Driven by the author’s interest in the environment and conservation, the principal motive for this research study is to understand the success of initiatives to encourage Australian consumers to adopt sustainable practices in their daily lives. Using an extended version of the Theory of Planned Behaviour (TPB), it explores the effects of Australians’ attitudes, perceived behavioural control (PBC), subjective norm, personal normative motives (PNM), internal ethics and moral intensity in predicting their sustainable behaviour and intentions. To achieve the aims of this study, four research questions and 17 hypotheses are examined in detail using exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modelling (SEM). The survey questionnaire is based on the extant literature, adapted to the sustainable context and pre-tested using depth interviews. The quantitative data is collected using an online survey with a final representative sample of 511 Australians. The study demonstrates that sustainable behaviour and intention is most reliably measured by 'likely behavioural intention' (LBI) and 'lifestyle behaviour'. The sample was most likely to adopt sustainable practices which involved little effort or cost, and least likely to adopt more expensive products such as double-glazed windows. The key driver of sustainable behaviour and intention was consumers’ 'internal ethics' which reflects their beliefs that they have an obligation to live sustainably. The other exogenous constructs had a lesser effect on their behaviour and intention, suggesting that the TPB was only moderately useful in predicting behaviour and intention. While many Australians have started their journey towards adopting sustainable practices, this study suggests that the theory does not provide a complete account of the reasons for sustainable intention and behaviour. Engaging in sustainable practices is a highly complex topic, and further research is required to understand the additional measures and constructs that need to be included in order to better explain the variance in Australians’ behaviour. This particularly applies to understanding the issues that drive behavioural change as well as the limiting factors that prevent their adoption, particularly the cost. Understanding the factors that would make consumers pay more for sustainable products and services, as well as the factors that would increase their sense of ethical obligation, could also be a topic for future research.

description: Isn’t the report card just a way to distinguish the “have” schools from the “have not” schools? This is the ninth in a series of frequently asked questions that can be found on the school performance section of the Fraser Institute’s website. Importantly, the report cards in question are both produced and published by the Fraser Institute, an independent public policy research group that ranks Canadian elementary schools on a set of indicators gleaned from the results of provincial standardized testing. While the Fraser Institute answers this question with a simple No, the thesis research presented here uses a mixed methods approach to examine the accuracy of this simplistic answer. Using socioeconomic data and regression analysis, this research endeavors to uncover if standardized test results can indeed stand independently of class and other demographic factors to produce a valid point of school comparison. This research also provides an in depth exploration of the Fraser Institute’s annual elementary school report card from the perspective of current elementary teachers in Ontario. Lastly, this research presents findings regarding the ways that parents of elementary school children use and understand the Fraser Institute’s school ratings.

description: In Canada, bail supervision programs were developed, in partnership with community-based organizations, to promote bail compliance and provide supervision to accused persons who would otherwise have been detained in remand custody. While many of these programs use traditional risk assessment tools to guide supervision, limited research has been conducted on their effectiveness in the bail supervision context. Adopting a quantitative as well as qualitative methodology, this study uses a representative sample of 100 supervision clients from one Ontario bail program to examine the validity of its risk tool – Service Planning Instrument™ (SPIn) Pre-Screen – as well as demographic and criminal justice factors, in predicting bail supervision outcomes. Analyses suggest that SPIn lacks predictive validity in the bail supervision setting. These findings are discussed within the broader context of net widening, as well as the greater bail/remand crisis and the culture of risk aversion that pervades the Canadian criminal justice system.

description: Data aggregation is an important technique in wireless sensor networks. The data are gathered together by data fusion routines along the routing path, which is called data-centralized routing. We propose a localized, Delay-bounded and Energy-efficient Data Aggregation framework(DEDA) based on the novel concept of DEsired Progress (DEP). This framework works under request-driven networks with realistic MAC layer protocols. It is based on localized minimal spanning tree (LMST) which is an energy-efficient structure. Besides the energy consideration, delay reliability is also considered by means of the DEP. A node’s DEP reflects its desired progress in LMST which should be largely satisfied. Hence, the LMST edges might be replaced by unit disk graph (UDG) edges which can progress further in LMST. The DEP metric is rooted on realistic degree-based delay model so that DEDA increases the delay reliability to a large extent compared to other hop-based algorithms. We also combine our DEDA framework with area coverage and localized connected dominating set algorithms to achieve two more resilient DEDA implementations: A-DEDA and AC-DEDA. The simulation results confirm that our original DEDA and its two enhanced variants save more energy and attain a higher delay reliability ratio than existing protocols.

Publisher: name: Zenodo
Year: 2024

description: Due to the low coherence times of present-day quantum computers, it seems necessary to reduce quantum circuit depth to be as small as possible, in order to increase the reliability of quantum computers. In this talk, I will present some basic ideas for doing so, which date back to Shor's late-1990s constructions for fault-tolerant quantum computing. After that, I will illustrate these quantum circuit constructions for the application of multivariate trace estimation. This application concerns estimating the trace of a product of quantum states, known to be a BQP-complete problem. Finally, I will sketch a 2D architecture design for these circuit constructions, with the aim of motivating more in-depth studies of this problem from a quantum computer architecture perspective.

description: The transition from elementary to secondary school is an emotionally and socially complex time when adverse behaviors appear, such as decreased levels of physical activity (PA). Behavioral and environmental factors that influence PA during this time are poorly understood. Therefore, we aimed to identify factors that influence PA as adolescents transition to secondary school. Qualitative interviews were conducted with a sample of 27 ethnically diverse child–parent dyads within the public-school system in British Columbia, Canada (50% boys, 68% mothers, 25% White). The interviews probed for environmental and behavioral factors in school, family, and social contexts that potentially initiated changes in PA, specifically related to the adolescents’ transitions. Interviews were recorded and transcribed verbatim. Thematic analyses identified factors at the individual, social, familial, and school levels that may trigger adolescents to change their participation in PA as they transition from elementary to secondary school. Twenty-two factors emerged from the qualitative analysis including school factors (8), household factors (3), social factors (4), and intrapersonal factors (7). These findings contribute to a better understanding of adolescents’ PA behaviors and highlight the influence of changing environments as they transition from elementary school to secondary school.

description: Losses of volatile compounds during baking are expected due to their evaporation at the high temperatures of the oven, which can lead to a decrease in the aroma intensity of the final product, which is crucial for gluten-free breads that are known for their weak aroma. Volatiles from fermentation and lipids oxidation are transferred from crumb to crust, and they flow out to the air together with Maillard and caramelisation compounds from the crust. In this study, the release to the oven of volatile compounds from five gluten-free breads (quinoa, teff and rice flours, and corn and wheat starches) and wheat bread during baking and toasting was measured in real-time using proton transfer reaction-time of flight-mass spectrometry (PTR-ToF-MS). Baking showed different volatile release patterns that are described by bell-shaped curves, plateaus and exponential growths. Flour-based breads had the higher overall volatile release during baking, but also high ratios in the final bread, while starch-based breads showed high pyrazine releases due to moisture losses. Meanwhile, toasting promoted the release of volatile compounds from the bread matrix, but also the additional generation of volatiles from Maillard reaction and caramelisation. Interestingly, gluten-free breads presented higher losses of volatiles during baking than wheat bread, which could partially explain their weaker aroma.
Reliable materials performance data from impact testing
Creators: name: Kariem, Muhammad Agus
Publisher: name: Swinburne

description: Swinburne University of Technology has a wide range of facilities for measuring the mechanical properties of materials under impact and high speed loads. The facilities include a drop‐weight test machine, three sets of split Hopkinson pressure bar (SHPB), a gas gun and an INSTRON test machine, which are capable of conducting experiments in the strain rate range of 10-3 to 103 s-1. It is difficult to conduct reliable experiments in the strain rate range of 102 to 103 s-1, which is vital, for instance, to the development of crash‐worthy vehicles and the high-speed machining of aerospace metals. The SHPB has been commonly used for the dynamic characterisation of materials for over a century. The high strain rate testing capabilities and simplicity of the technique are reasons for its popularity. This technique can be used for the dynamic characterisation of various materials such as brittle, ductile and soft materials. This technique can also be applied in several load directions such as compression, tension, torsion, shearing and triaxial tests. It also can be used for conducting impact bending to determine the dynamic fracture toughness of materials. Despite its longevity, the Hopkinson bar technique has not been standardised yet. The standardised SHPB technique is necessary in order to provide guidelines for determining the intrinsic material properties. This thesis fills a gap covering materials that has not been discussed yet in previous researches. This research examines the reliability of the compressive SHPB on the metal testing by experimental work, in parallel with the numerical simulation. The main outcomes of this thesis include the quality of bar production, standardisation of the pressure bar, specimen design criteria, consistency of the testing results, identification of measurement uncertainties, effect of paper layer as pulse shaper, and detailed data processing and analysis. It was found that if a greater care and preparation of apparatus and the specimen were taken, and then followed by a standardised data processing and analysis, the SHPB technique produced quite consistent results (within an acceptable error of less than 5%). This consistency was confirmed by the apparatus itself (repeated test) and inter-equipment (compared with the quasistatic and round-robin tests). Based on those results, the author believes that the SHPB technique could and should be standardised in the future.

description: Background and Research Goals. This study aims to see the association between worldviews and HPV vaccine risk perceptions in a sample of Canadian undergraduate students enrolled in Health Sciences and Business programs at the University of Ottawa. It is a follow-up to the Kahan et al. (2010) research in the U.S. that showed the association to be present in a nationally representative U.S. sample. In addition to searching for this association in the Canadian context, this study examines whether worldviews differ between (a) men and women; and (b) students with health sciences and with business degrees. Furthermore, this study tests a set of candidate questions for supplementing the worldview questionnaire of Kahan et al. (2010). Design and Analysis. The data for the study was collected using an Internet-based questionnaire and the study was conducted in two phases. During the first phase, a customized worldview questionnaire was administered. During the second phase, questions related to HPV and Canadian healthcare system were presented. In order to analyze the data, regression models, correlation matrices, and MANOVAs were employed. Results. The findings of this study are that worldviews are related to HPV vaccine risk perceptions. However, though hierarchism was a better predictor then individualism in the Kahan et al. (2010) study, our present research indicates that individualism is a better predictor. Also, our findings, contrary to those of Kahan et al. (2010), suggest that the more individualistic a person is, the more likely he or she is to perceive the vaccine as being safe. With respect to gender, men were more hierarchical. Also, when females in health sciences were compared to women in business, the latter were also more hierarchical. Finally, three healthcare items were identified as possibly benefiting from refinement and inclusion in a worldview instrument more suited for the Canadian context.
Combining Balanced Score Card and Data Envelopment Analysis for Analyzing the Performance of Small Scale Fisheries

description: The balanced scorecard (BSC) is an accepted methodology for putting strategy into action. The BSC provides a comprehensive performance measurement for an organization with respect to both financial and non-financial perspectives, including the triple bottom line of planet, people, and profit. Through various implementations to companies, organizations, and sectors, balanced scorecards have been used widely both for strategic purposes, as well as for more tactical focus for auditing current performance. BSC implementation is particularly adequate when integrated with the operational processes of the organization. The integration between the strategic plan and the financial and operational plans proceed via the business process model that covers the operational processes associated with the objectives of the organization in the strategy map. In this way, BSC is a tool for real-time monitoring of performance as well as providing the crucial linkage to the organization’s strategy that enables the proper implementation of the organization’s strategy. Data envelopment analysis (DEA) has been widely applied for measuring the efficiency of a specific decision-making unit (DMU) against a projected point on an efficiency frontier. DEA is therefore particularly suitable for measuring the organizational efficiency based on the BSC indicators, which are defined as Key Performance Indicators (KPIs). In the commercial fisheries sector, sustainable strategy of fisheries organizations can be gained by running the current operations more effectively, and by integrating processes enabling adaptation to change. The efficiency frontier of the DEA model can be used to calculate the efficiency of fisheries operations. The proposed research is undertaken as part of the Canadian Fisheries Research Network (CFRN) to investigate the application of BSC and DEA for defining commercial fisheries performance evaluation variables with respect to the objectives of environmental sustainability, economic viability, and social and cultural stability in compliance with, and in the absence of, performance monitoring alleged in the Fisheries and Oceans, Canada Integrated Fisheries Management Plans (IFMP). The combination of BSC-DEA methodologies is developed in this research as a required performance monitoring system suitable for IFMPs for analyzing the relative efficiency of commercial fisheries case studies across Canada towards incorporating best sustainable practices in the industry.
In defence of democracy

Publisher: name: Swinburne
Year: 2024

description: Through a synthesis of Antonio Gramsci and Pierre Bourdieu's ideas the aim of this work is to reveal how, in establishing the existing cultural hegemony, the term 'democracy' has been hijacked, becoming an instrument of political subjugation rather than a condition for human emancipation. It will be argued that it is necessary to rethink political discourse by taking up democracy as a central guiding political concept, thereby reviving its original meaning. It will be necessary to first highlight the crisis in Australia's liberal democracy where, on a whole range of issues, conditions necessary for democracy have been systematically undermined. By analysing the ideas and political methods of those hostile to democracy, it will be argued that ironically, they have been more successful at implementing Gramsci's political strategy of a war of position. This was achieved through, to use Bourdieu's terminology, a manipulation of capital distribution, the structural dynamics of fields and the habitus of political agents, leading to the displacement of democracy by corporatocracy. Yet if democracy were to be reclaimed and upheld, a counter war of position could be effectively launched. But it will be necessary to provide reasons for reclaiming democracy on philosophical grounds as well as strategic. The question of why organising social relations democratically rather than through an oligarchy will be raised and explored. However, to defend democracy it is not enough to show its desirability. It will also be necessary to confront a number of serious difficulties that presently exist in Australian politics. Global capitalism has shifted the balance of power away from labour, as transnational corporations break free of constraints set by national governments. To add to the complications, social divisions are multiplying and widening, making it more difficult to find common ground for political unity among the dominated. In attacking all attempts at theoretical cohesion, postmodernism has effectively eliminated the intellectual basis for opposing corporatocracy. Moreover, advocates on the left of Australian politics share the same assumptions as their opponents, despite claiming to be at the cutting edge of radical politics. This has unwittingly helped legitimise scepticism towards grand narratives of emancipation. As an ideal to focus the counter-hegemonic struggle against corporatocracy, democracy could also facilitate unity while avoiding dogmatism and totalitarianism.

description: This dissertation examines reputation as a regulating force in online and offline relationships and transactions, arguing that reputation requires protection through the promulgation of new laws. Using John Locke’s “under-labourer” approach as its central method, this dissertation ultimately sets out a series of conclusions, which form a preliminary framework upon which appropriate reputation regulation might be built. Part I of this dissertation studies offers an interdisciplinary study of reputation. Chapter 1 examines the ways that reputation is created and maintained, the purposes for which it is used, and its role in risk management and trust. These understandings are then applied to reputation in process. Chapter 2 explores formal reputation systems and the ways in which user investments and desires become written into reputation such that multiple levels of “dominant” norms may be simultaneously operant. Chapter 3 shows this normative force also operating on social network sites, shaping identity performances. Finally, having established these intersections and the regulating power of norms upon reputation, the effect of such performances is examined in chapter 4, which identifies reputation’s gatekeeper role in offline and online spaces and the risks this can create when information is accessed or employed without an understanding of the norms which have shaped that information. Thus reputation is shown as a socially negotiated and co-created process which exerts an unseen hegemonic force, with dominant political, economic and ideological interests embedded in seemingly social norms. These norms are enforced via reputation, which takes on a gatekeeper role, regulating access to a variety of spaces, information, and economic opportunities. Part II begins with an examination of the current forms of legal and quasi-legal regulation of reputation that exist, ultimately finding that none of them is fully applicable to the complexity of reputation. Having established this complexity and shown that current approaches are inadequate, chapter 6 moves on to examine and then reject the neoliberal approach currently applied to these issues, finding its focus on individual responsibility to be inadequate and inappropriate, calling instead for a mode of regulation that understands reputation within its social context.

Development and Implementation of a Preconditioner for a Five-Moment One-Dimensional Moment Closure

description: This study is concerned with the development and implementation of a preconditioner for a set of hyperbolic partial differential equations resulting from a new 5-moment closure for the prediction of gas flows both in and out of local equilibrium. This new 5-moment closure offers a robust and efficient system of first-order hyperbolic partial differential equations that has proven to provide an accurate treatment of one-dimensional gases, both in and for significant departures from local thermodynamic equilibrium. However, numerical computations using this model have proven to be difficult as a result of a singularity in the closing flux of the system. This also causes infinitely large wavespeeds in the system. The main goal of this work is to mitigate these numerical issues. Since the solution of a hyperbolic system is characterized by the waves of the system, one could suggest to scale these wavespeeds to remove the arbitrarily large speeds without altering the solution of the system. To accomplish this, this work starts with a detailed study of the behaviour of the system’s wavespeeds, given by the eigenvalues of the flux Jacobian of the system. Since, it is not possible to solve for these eigenvalues explicitly, it is suggested to approximate them by interpolation between the few states at which these waves can be solved for explicitly. With an estimate for the wavespeeds, the nature of the singularity in the system can be analyzed mathematically. The results of this mathematical analysis are used to develop a preconditioner matrix to remove the singularity from the model. To implement the proposed preconditioned model numerically, a centred-difference scheme with artificial dissipation is proposed. A dual-time-stepping strategy is developed and implemented with implicit Euler time marching for both physical and pseudo time iteration. This dual-time treatment allows the preconditioned system to remain applicable to time-accurate problems and is found to greatly increase the robustness of the solution of the steady-state problems. Solutions to several canonical problems for both continuum and non-equilibrium flow are computed and comparisons are made to classical models.

description: The present work investigates the structure of supersonic turbulent deflagration typically observed as precursors to the onset of detonation. These high-speed flames are obtained after detonation interaction with cylindrical obstacles. Two mixtures having the same propensity for local hot spot generation were used, namely stoichiometric hydrogen-oxygen and methane-oxygen. It was shown that the methane mixture sustained turbulent fast flames, while the hydrogen mixture did not. Three visualization techniques, Schlieren, shadowgraph, and direct chemi-luminescence were implemented to record the evolution of the structure following the detonation interaction with the obstacle. Detailed high-speed visualizations of the nearly two-dimensional flow fields permitted the identification of the key mechanism involved. It was found that the shock reflections in methane permitted strong forward jets behind periodically formed Mach shocks on the front of the deflagration. These hot spots in the re-circulation zones of the jets provided local enhancement of the reactivity through mixing, supporting the formation of new generations of new hot spots. The hot spot formation was identified as the prominent difference between the different mixtures. These reactive pockets further sustained the shock reflection processes. As the methane-oxygen fast flame propagates along the channel, the wave front was observed to organize into fewer modes and eventually led to a reflection capable of the transition to detonation. In the hydrogen mixtures, at similar thermo-chemical parameters, self-sustained fast flames were not observed. Following detonation interaction in the hydrogen mixture, reactive reflections were observed. As the wave propagated downstream after a limited number of reactive reflections, the wave developed a planar wave front and decayed as the reaction zone trailed with an ever-increasing distance. It is postulated that the absence of the forward jets did not allow such fast flames to establish. This jetting slip line instability in methane shock reflections was recently found to be correlated with the low value of the isentropic exponent and its control of Mach shock jetting described by Mach & Radulescu. The lack of the forward jetting of the slip line in the hydrogen mixture with the higher value of the isentropic exponent is in agreement with the Mach & Radulescu.

description: Prostate cancer (PC) treatment leads to impairment of sexual function. The Prostate Cancer Supportive Care (PCSC) Program’s Sexual Rehabilitation clinic (SRC) assists patients and their partners with sexual recovery using a biopsychosocial approach to rehabilitation. This study characterizes patients seen in the SRC between July 2013–1 July 2019. Data was retrospectively abstracted from clinic records. In total, 965 patients were seen over 3391 appointments during the study period. Median age (standard deviation (SD)) was 66 years (SD = 7.1), 82.0% were partnered, yet 81.7% attended appointments alone. 88.0% were treated with surgery, 5.1% with brachytherapy, 3.7% with external beam radiation (EBRT), 1.8% with combined brachytherapy and EBRT, and 1.4% with androgen deprivation therapy. In total, 708 patients (73.4%) attended ≥1 follow-up appointment. Median time (SD) between end of prostate cancer treatment to first SRC appointment was 270 days (range 0–7766). The mean (SD) self-reported overall sexual satisfaction (extracted from International Index of Erectile Function-5 (IIEF-5)) significantly increased both with erectile aids (1.69 (SD = 1.52) to 2.26 (SD = 1.66), p < 0.001, n = 148) and without erectile aids (1.71 (SD = 1.44) to 2.35 (SD = 1.57), p < 0.001, n = 235). This study provides guidance for further investigation to refine treatment, wait-times, support, and/or resource offerings in this type of program.
On the Structure of Metal Oxalate Anions: Theory and Experiment

Ion Mobility
Infrared Multiphoton Dissociation

description: Anionic metal-oxalate complexes have been generated in the gas phase and an attempt at determining plausible structures were made. Two different experimental techniques were coupled to mass spectrometry: Infrared Multiphoton Dissociation (IRMPD) and ion mobility. Both techniques were compared to theoretical structures calculated using various levels of theory. With the use of IRMPD, frequencies were generated for each complex and compared to theoretical frequencies. Plausible structures for all complexes were found using the M-series of density functional levels of the theory when the 6-311+gd basis set was used and Bhandhlyp functional was appropriate for the lanl2dz basis set. Using ion mobility allowed for collision cross-sections to be calculated and compared to theoretical collision cross-sections of the various structures. Unfortunately no plausible structures were determined using this technique due to a lack of calibrants for the negative mode of ion mobility.
Dynamic and Modal Responses of the Grouted Multiple Strands Stay-Cables of the Bill Emerson Memorial Bridge
Creators: name: Xiangwen, Zuo

Year: 2015

description: Cable-stayed bridges are massive structures which rely on all their structural components for achieving the structural stability. Usually bridge stay-cables are the most flexible elements of the cable-stayed bridge structures, thus continuous efforts are made for improving their performance under different loadings. A new technology of constructing and installing the inclined bridge stay-cables, involves using internal strands grouted together in a cement paste or in a polymer gel material; such method has the advantage of allowing replacing of rusted strands individually, without affecting the functionality of the entire bridge stay-cable. However, recent studies have reported a change in natural vibrations of such inclined cables used for the construction of cable-stayed bridges. The current research aims at clarifying the dynamic properties of the internal strands in the cable, under the influence of the grout surrounding material and the interaction with the other inner strands under different wind loading scenarios. The effectiveness of the crossties in mitigating the wind-induced vibration has also been studied. A finite element model was developed using the nonlinear analysis through the Abaqus commercial software. Some assumptions were made for modelling the stay-cables of the Bill Emerson Memorial Bridge, and to simulate the inner strands and the grout interaction. Both modal and time-history analyses were carried out on the stay-cables fan which connects the tower to the main span deck of the Bill Emerson Memorial Cable-stayed Bridge. The natural frequencies and the vibration mode shapes of a single cable, or group of cables respecting the arrangement of the inclined cables of the bridge has been determined, as well as the displacements under the field wind loads at different points in the stay-cables network. The results show how the behaviour of the cables differs from the previous research on the stay-cable which employed only a simplified beam element as one uniform property of the cable. Several comparisons haven been made between the results obtained in the current study and outcomes reported in the existing literature; the effectiveness of the crossties has been partly verified. Also the results of the modal analysis were compared with the site measurements performed for the Bill Emerson Memorial Bridge and relatively good agreement was found for the natural frequencies and the mode shapes of the inclined stay cables.

description: The use of the lithium ion batteries has significantly increased over the last few years and is expected to increase in the future, mainly due to their application in electrical cars [1]. Recycling of the batteries is essential to safely dispose hazardous materials as well as to recover valuable elements including cobalt, copper, nickel, manganese, lithium and others. A growing amount of used manganese containing materials in the battery cathode [2], will lead to increasing concentrations of manganese present in the high temperature smelter slag. In order to optimise the recycling process of these metals, accurate information is required on the phase equilibria in the Al2O3-CaO-Li2O-'MnO'-SiO2 system.
Divergent Role of PAX2 in the Etiology and Progression of Ovarian Cancer

Ovarian cancer

description: PAX2 is a transcription factor that is essential for development. Aberrant expression of PAX2 in adult tissues is associated with carcinogenesis and experimental evidence shows that PAX2 generally exhibits oncogenic properties. Although PAX2 is not expressed in normal ovaries, it is highly expressed in low malignant potential and low-grade epithelial ovarian tumors, suggesting that PAX2 induction in ovarian surface epithelium (OSE) may contribute to transformation. Herein, we provide evidence that expression of PAX2 in normal murine OSE (mOSE) cells enhances their proliferation and survival and, when combined with loss of P53, induces tumorigenicity. In addition, OSE cells are known to gain an epithelial phenotype and express epithelial markers prior to their transformation. This study revealed that PAX2 induction in mOSE cells results in an enhanced epithelial phenotype associated with reduction of the epithelial-mesenchymal transition markers, SMA-α and COX-2. Furthermore, PAX2 inhibits the mesenchymal phenotype induced by TGF-β and reverses the TGF-β-mediated induction of both SMA-α and COX-2, in mOSE cells. Toward tumor progression, we found that when PAX2 was expressed in murine ovarian cancer cells, it enhanced or inhibited their aggressiveness, depending on the model system. In OSE cells transformed by K-RAS and MYC, PAX2 inhibited P53 accumulation and increased the level of pERK1/2 and COX-2. In addition, PAX2 inhibited apoptotic induction in these tumors, while increasing angiogenesis, both of which are enhancers of tumor aggressiveness. However, in a murine model of high-grade serous ovarian cancer, PAX2 expression reduced tumor mass and improved animal survival, likely via reduced proliferation and metastasis. Mechanistic studies showed that PAX2 increased Htra1 and decreased COX-2 in those tumors. Both HTRA1 and COX-2 are novel downstrream targets for PAX2 that are identified in the current study. These results suggest that PAX2 may not act as a classical oncogene or tumor suppressor in ovarian cancer; rather, it modulates tumorigenesis differently, depending on the tumor context. The observation that PAX2 targets distinct biological and molecular pathways might help to guide future studies to different therapeutic targets in low-grade vs. high-grade cancers.

Fuzzy logic system

description: In this research work, an approach for fire detection and estimation robots is presented. The approach is based on type-2 fuzzy logic system that utilizes measured temperature and light intensity to detect fires of various intensities at different distances. Type-2 fuzzy logic system (T2 FLS) is known for not needing exact mathematic model and for its capability to handle more complicated uncertain situations compared with Type-1 fuzzy logic system (T1 FLS). Due to lack of expertise for new facilities, a new approach for training experts’ expertise and setting up T2 FLS parameters from pure data is discussed in this thesis. Performance of both T1 FLS and T2 FLS regarding to same fire detection scenario are investigated and compared in this thesis. Simulation works have been done for fire detection robot of both free space scenario and new facility scenario to illustrate the operation and performance of proposed type-2 fuzzy logic system. Experiments are also performed using LEGO MINDSTROMS NXT robot to test the reliability and feasibility of the algorithm in physical environment with simple and complex situation.
(Un)Compromising/In Tension: Critical Pedagogy and the Academy

description: In asking about the experiences of professors embodying and enacting tools of critical pedagogy, this thesis seeks to explore strategies of resistance to the hegemony of neoliberalism in the Academy. This research focuses on the Canadian university as characterized by neoliberal logic and the hierarchical practices of capitalism, patriarchy, and colonialism. By exploring the themes of neoliberalism, violence, tension, critical pedagogy, and anti-oppression, that are in turn rooted in personal testimony and lived experience of educators, this study seeks to challenge normative systems of knowledge production to expand and explore subjugated knowledges. What is at stake is developing strategies that may be cultivated and documented as critical pedagogical tools that work toward collective imaginings of resistance.
Negotiating Perceptions and Constructing Identities: Muslim Strategies in St. John’s, Newfoundland

description: This thesis examines how Muslims in Canada negotiate perceptions in their interactions with non-Muslims and other Muslims. What strategies do Muslims in Canada use to combat these perceptions? How do perceptions of Islam and Muslims impact Muslims’ constructions of identities? In order to answer these questions a case study was conducted in St. John’s, Newfoundland. Interviews with Muslims living in St. John’s explored how they respond to perceptions of Islam and how they negotiate their identities in everyday life. This study found that perceptions of Islam and Muslims played an important role in the construction of Muslims’ identities despite the low incidence of Islamophobia. Perceptions of Islam and Muslims often led to an increase in knowledge of Islam, an increase in affiliation with their Muslim identities and increase in religiosity. However, an alternative impact was a distancing from Islam. Participants used numerous strategies to combat negative perceptions of Islam and Muslims including taking up an educator role and becoming representative. Further, many participants separated culture and religion, creating a ‘true’ Islam and contributing to islamophilia. However, other participants challenged philic and phobic accounts of Islam by voicing their lived practices and presenting multiple and dynamic Islams.
