description: Our laboratory has been interested in the effects on leukocytes of reactive oxygen intermediates (ROI), such an superoxide (O$\sb2{\bar\cdot}),$ produced during the "respiratory burst". Upon stimulation, such cells employ the NADPH oxidase to reduce O$\sb2$ to form O$\sb2{\bar\cdot}$ using NADPH from the hexose monophosphate shunt (HMPS). In order to further study the effects of ROI, we planned to perform genetic manipulations on U-937 cells, a monoblastic cell line capable of differentiation into more mature leukocytes. In Part A, conditions to promote maximal U-937 differentiation into respiratory burst-competent cells were developed, thus allowing for such manipulations. Retinoic acid (RA) was found to be a potent inducer of a functional NADPH oxidase and HMPS, and of various mRNAs for their components. RA also reduced cell proliferation and altered cell morphology. The effects of RA were augmented by nitric oxide (NO$\cdot$) donors, believed to act by increasing intracellular cGMP levels. Among the NO$\cdot$ donors rested, only glyceryl trinitrate induced differentiation in the absence of RA. Since heparanase, an endoglycosidase which degrades heparan sulfate (HS), is active in mature leukocytes, the possibility that heparanase might serve as another U-937 differentiation marker was investigated. Because of a laboratory interest in cloning a heparanase cDNA based on enzymatic activity, Part B was devoted to the development of a heparanase assays for these purposes and for characterization of heparanases. A refined PAGE-based heparanase assay was used to test various cell types; KNRK cells were found to be the most active. Not previously characterized, KNRK heparanase was found to be a relatively stable enzyme with pH 6 optimum, inhibitable by heparin and able to digest a variety of HS substrates. Heparanase activity was virtually absent in immature U-937 cells and was only marginally increased during differentiation. Development of a more sensitive fluorescence-based heparanase assay was initiated.

description: A three-dimensional transient equation for the flow of any time-independent incompressible fluid, Newtonian or non-Newtonian, through compressible porous media has been derived. Equations applicable to Ostwald-de Waele fluids, Bingham fluids, and Newtonian fluids are deduced directly from the general transient equation. It is shown that the one-dimensional filtration equation derived by Tiller is only a special case of the general flow problem. An equation describing the fowl of a compressible fluid (ideal gas) through compressible porous media is also developed. It reduces to the ordinary unsteady flow equation through incompressible porous media when the porosity and specific cake resistance are constant. The usefulness of the integral method in arriving at a reasonable solution to the one-dimensional constant pressure filtration problem is tested utilizing a linear pressure profile through the cake.

description: Fenitrothion (0,0-dimethyl-0-(4-nitro-m-tolyl) phosphorothioate) was absorbed by germinating seeds of eastern white pine; Pinus strobus L. (Moench) Voss, white spruce; Picea-qlauca L., and yellow birch; Betula alleghaniensis L., from an aqueous solution containing 10 ppm of the pesticide. Metabolism of the pesticide was examined in young seedlings with OC14H3 labelled fenitrothion. Fenitrothion was shown to be detoxified by dealkylation in white pine via a glutathione dependent S-alkyl transferase enzyme to form desmethyl fenitrothion and S-methyl glutathione. Dealkylation was also found in white spruce and yellow birch seedlings. The pesticide was activated to form fenitro-oxon, which is more toxic than the parent compound. The desmethyl form was shown to be reactivated via alkylation by fenitrothion to form S-methyl fenitrothion which is a more potent cholinesterase inhibitor than the parent compound. Treatment of the seeds at higher concentrations of 1000 ppm fenitrothion inhibited germination of yellow birch seeds but not white pine or spruce. Severe depletion of tissue glutathione levels was shown to be related to toxicity in yellow birch which absorbed much higher levels of pesticide than the two coniferous species. Fenitrothion and seven derivatives of the compound were tested for mutagenicity via alkylation of replicating DNA in an indicator strain of Salmonella typhimurium, sensitive to base-pair substitutions caused by alkylating agents. No mutagenic activity was evident for fenitrothion or its derivatives in this system.

description: Forests contain a majority of the aboveground carbon (C) found in ecosystems, and understanding biomass lost from disturbance is essential to improve our C-cycle knowledge. Our study region in the Wisconsin and Minnesota Laurentian Forest had a strong decline in Normalized Difference Vegetation Index (NDVI) from 1982 to 2007, observed with the National Ocean and Atmospheric Administration’s (NOAA) series of Advanced Very High Resolution Radiometer (AVHRR). To understand the potential role of disturbances in the terrestrial C-cycle, we developed an algorithm to map forest disturbances from either harvest or insect outbreak for Landsat time-series stacks. We merged two image analysis approaches into one algorithm to monitor forest change that included: (1) multiple disturbance index thresholds to capture clear-cut harvest; and (2) a spectral trajectory-based image analysis with multiple confidence interval thresholds to map insect outbreak. We produced 20 maps and evaluated classification accuracy with air-photos and insect air-survey data to understand the performance of our algorithm. We achieved overall accuracies ranging from 65% to 75%, with an average accuracy of 72%. The producer’s and user’s accuracy ranged from a maximum of 32% to 70% for insect disturbance, 60% to 76% for insect mortality and 82% to 88% for harvested forest, which was the dominant disturbance agent. Forest disturbances accounted for 22% of total forested area (7349 km²). Our algorithm provides a basic approach to map disturbance history where large impacts to forest stands have occurred and highlights the limited spectral sensitivity of Landsat time-series to outbreaks of defoliating insects. We found that only harvest and insect mortality events can be mapped with adequate accuracy with a non-annual Landsat time-series. This limited our land cover understanding of NDVI decline drivers. We demonstrate that to capture more subtle disturbances with spectral trajectories, future observations must be temporally dense to distinguish between type and frequency in heterogeneous landscapes.
The construction of political corruption in "The Globe and Mail" from 1990-2000

description: Despite a loss of readership and revenue, newspapers, one of the main providers of new information to the public, continue to playa major role in helping to shape public debate about social problems. The news media is therefore one of the primary ways for claims-makers to distribute their claims to a large audience. By presenting the claims, the news media alters the claims and re-presents them. These new claims represent one possible worldview, and because of the news media's major role in public debate, these claims may be very influential. A review of the research literature on political corruption shows that few media studies about political corruption have been conducted in Canada. Furthermore, the research literature uses a wide variety of different definitions for what constitutes political corruption, making it extremely difficult to compare and analyze different articles in the research literature. I chose to examine how The Globe and Mail, which many people consider to be Canada's premier newspaper, perceived, reported, and describes political corruption. My goal is to explore how The Globe and Mail describes political corruption and presents claims-makers' claims, and how these claims may influence debate. I used a quantitative content analysis to analyze newspaper articles about political corruption published in The Globe and Mail from 1990-2000. I found that numerous articles published in The Globe and Mail identified political corruption as a serious problem with serious effects on Canadians. Grand corruption in the Federal level of government was the most identified type of corruption, with favouritism as the main form. For quotes, The Globe and Mail primarily used State sources and alleged offenders. The structure of Canada's political system was identified as the primary cause of political corruption, while solutions were constructed to include either increased accountability or stronger laws. The information provided by The Globe and Mail usually came from others sources, and there was very little independent investigation of claims. These results show that The Globe and Mail presents a limited debate about political corruption. The focus on presenting State viewpoints may limit discussion of other possible causes and solutions, and this limited discussion may result in ineffective legal responses.
Unfolding interactivity: exploring user power through a visual interpretation model
Creators: name: Chang, Pai-Ling
Publisher: name: Swinburne
Year: 2024

description: This design research project focuses on two primary areas of enquiry -- the phenomenon of interactivity in digital media design and how ideas from outside interaction design might expand the understanding and application of interactivity within the field. Interactivity is generally seen as the user’s ability to access information. For certain writers and practitioners, however, the idea of interactivity extends to user’s capacity to shape content and meaning, extending the experience of digital media. Using a combination of theoretical discussion and design experimentation, the research explores the second perspective, proposing a model of interactivity that accepts user’s capacities for reflexivity and intervention. Anthony Giddens’s writings on human reflexivity support the idea of the ‘knowledgeability’ of human agents, that is, their capacity to understand the nature of their circumstances and to act upon them. Theories of postcolonial identity argue that visualities produced by diasporic individuals reveal critical reflexivity in the mixing of cultural meanings and materials. The research uses these ideas to conceive how users might experience autonomy, agency and self-determination in digital media contexts. Taking processes of visual interpretation as a model for interactivity, the research explores how users can exert an influence over subject matter, achieve an enhanced creative experience and ultimately produce their own content. Central to the research is an experimental multimedia program that allows users to imaginatively manipulate aspects of the work of the Chinese poet Li Po (701-762CE). While it mobilizes the cultural capital of contemporary Chinese audiences, it accepts that the diverse forces at play on these audiences distance them from the plane of meaning as it operated for Li Po. Using the program gives Chinese audiences access to a cultural heritage that is fast being displaced by Western-style media and consumer culture. The model of interaction advanced in the prototype allows for the reconfiguration and conceptual resignification of Li Po’s work, suggesting (1) the capacity to critically negotiate culture and identity and (2) design strategies to create new modalities of richness and complexity in the reception of digital media products. The design prototype provides fresh perspectives on some fundamental questions in multimedia design, namely, what is interactivity and how can designers harness it to create more stimulating and empowering experiences for users?
Characterization of Microreactors with Respect to Pressure Drop, Heat Transfer and Mixing Efficiency

description: Microreactors have been shown to greatly improve process in the pharmaceutical and fine chemical industry and provide solutions to many of the drawbacks that exist in batch and semi-batch processes. However, industry experts agree that there is a need for a standard method of analysis to compare the performance of complex microreactor geometries. This study provides a method to compare the pressure drop and mixing efficiency on a common scale and observes the effect of reactor materials on the overall heat transfer. Semi-empirical pressure drop modeling determined the pressure drop along the mixing zone and showed that the axial mixing of the tangential mixing unit had the highest friction factor. Mixing efficiency was characterized using the 4th Bourne reaction and showed that under turbulent conditions at a given energy dissipation the mixing efficiency is independent from geometry and confirmed that their mixing occurs at the same mixing time scale. However, after increasing the viscosity of the system, the geometries differed in their transition from turbulent to laminar. The tangential mixing unit showed to have lowest regime transition Reynolds number. The effect of reactor materials was observed with respect to heat transfer performance. Empirical modeling determined that the Hastelloy reactor provided a heat transfer rate up to 40% greater than a glass system and was limited by the convective heat transfer of the reactor channels whereas the glass reactor was limited by the thermal conductivity of the reactor wall.
In science we trust: Dissecting the chimera of New Atheism
Creators: name: Tomlins, Steven

Subjects: subject: Religion, General.
subject: Philosophy of Science.

description: New Atheism is a neologism that is explicitly linked to four public intellectuals: Richard Dawkins, Sam Harris, Christopher Hitchens, and Daniel Dennett. At the heart of this movement are the five books these four atheists have written specifically on the topic of religion. Throughout the New Atheist literature science is conceptualized as the most powerful force for secularization in the modern era. This thesis is a textual discourse analysis of the New Atheist literature, with a primary focus on how the themes 'secularization' and 'science' are framed. It will explore how notions of secularization and science often bleed into each other, with science being portrayed as necessarily opposed to religion. It will also highlight the New Atheists' similarities and diversities of opinion on these matters, as well as examine where their stances are located in the broader debates concerning the so-called secular/religious divide and the interactions between science and religion.
Turn-of-the-century Canadian women writers and the "New Woman".
Creators: name: MacIntyre, Christine Anne.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Literature, Canadian (English).

description: This study examines the literature written by the generation of women who come between pioneering women writers such as Catharine Parr Traill and Susanna Moodie and contemporary women writers such as Alice Munro and Margaret Laurence, literature which helps us to understand the tradition of New Woman writing present in Canada at the turn of the century. This thesis examines selected texts published between 1895 and 1910, a period of rapid urban and industrial expansion in Canada when women began seeing themselves and their roles in society in "new" ways. The first chapter of this thesis examines the concept of the "New Woman" in terms of its original connotations. The second chapter focuses on the representations of the "New Woman" in Lily Dougall's The Madonna of a Day. Sara Jeannette Duncan's A Daughter of Today is the subject of the third chapter. The final chapter examines short stories written by Canadian women journalists Kit Coleman, Ethelwyn Wetherald, and Jean Blewett. (Abstract shortened by UMI.)
Value system similarity, sex and value type effects on attributed marital adjustment.
Creators: name: Kindelan, Kevin M.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1977
Subjects: subject: Psychology, Social.

description: The report contains a review of the literature related to Byrne's (1971) attraction paradigm, Rokeach's (1973) theory of human values, and the relationship of value consensus to marital adjustment. A void in the literature was found in two areas: (1) the effect of terminal and instrumental value system similarity on attributed marital adjustment, and (2) the effects of various degrees of value system similarity on attributed marital adjustment. The present study was designed to investigate those areas. A simulated design was utilized wherein the effects of three independent variables on attributed marital adjustment were investigated. The three independent variables were sex of subjects with two levels, value type with two levels (terminal and instrumental), and degree of similarity of the value profiles of a "bogus couple" with three levels (22% similar, 50% similar, and 77% similar). A total of 447 undergraduate students served as subjects. A packet, containing the value profiles of two couples, questions about the marital adjustment of each couple and a posttest questionnaire, was administered to each subject. The major statistical analysis consisted of fourteen 2 X 3 X 2 analyses of variance. The results indicated that in all cases degree of similarity was a highly significant main effect. Post hoc analyses specified that, generally, a linear relationship was present between degree of similarity and attributed marital adjustment. A significant main effect for value type was not found. Results from the post-test questionnaire are also presented. An interesting finding was that both males and females rated value similarity as important in marital happiness, although females rated it as more important than did males. The results are discussed in terms of an extension of Byrne's (1971) attraction paradigm, limitations of the study in terms of generalizability, and the lack of a significant main effect for value type. Conclusions and directions for future research are also included.

description: Novel natural products (NPs) and their derivatives are important sources for drug discovery, which have been broadly applied in the fields of agriculture, livestock, and medicine, making the synthesis of NPs and their derivatives necessarily important. In recent years, biosynthesis technology has received increasing attention due to its high efficiency in the synthesis of high value-added novel products and its advantages of green, environmental protection, and controllability. In this review, the technological advances of biosynthesis strategies in the discovery of novel NPs and their derivatives are outlined, with an emphasis on two areas of host engineering and in vitro enzymatic synthesis. In terms of hosts engineering, multiple microorganisms, including Streptomyces, Aspergillus, and Penicillium, have been used as the biosynthetic gene clusters (BGCs) provider and host strain for the expression of BGCs to discover new compounds over the past years. In addition, the use of in vitro enzymatic synthesis strategy to generate novel compounds such as triterpenoid saponins and flavonoids is also hereby described.

description: Background: In Canada, prostate cancer (PCa) is the most common male cancer, and prostate cancer support groups (PCSGs) have prevailed for more than 20 years providing support to men with PCa and their families. While the format, focus and benefits of attending PCSGs have been reported little is known about primary physicians’ (PPs) perceptions of these groups. This article describes Canadian primary physicians’ views about face-to-face and web-based PCSGs. Methods Canadian based primary physicians (n = 140) attending a 2012 Continuing Medical Education Conference participated in a pilot survey questionnaire study. The 56-item questionnaire used in this study included six sets of attitudinal items to measure primary physicians’ beliefs about positive and negative influences of PCSGs, reasons for attending PCSGs, the attributes of effective PCSGs, and the value of face-to-face and web-based PCSGs. Results Results showed that PCSGs were positively valued, particularly for information sharing, education and psychosocial support. Poor inclusivity, privacy, and accessibility were identified as potential barriers, and recommendations were made for better marketing and web-based PCSGs to increase engagement with potential attendees. Conclusions Findings suggest PPs highly valued the role and potential benefits of PCSGs. Information provision and an educational role were perceived as key benefits amid the need to improve local and provincial marketing of PCSGs. The potential for web-based PCSGs to help in the support of PCa patients was also recognized.
Gallium nitride class-F power amplifier for UMTSWCDMA applications

Subjects: subject: Engineering, Electronics and Electrical.

description: The importance of wireless communications in today's telecommunications industry is indubitable. Wireless technologies are used in almost every aspect of our everyday life. Universal Mobile Telecommunications System (UMTS) technology has already implemented 3G communication standard for mobile communications. Power amplifiers are the most power consuming unit in wireless communication systems. The power amplifiers used in UMTS devices need to be highly efficient. Improved efficiency not only extends the battery life but also reduces the DC power consumption, transmitter size and weight. Although the power amplifiers used in existing second generation GSM (Global System for Mobile Communications) transmitters are highly efficient, they cannot be applied to UMTS/WCDMA since GSM uses the constant envelope feature of GMSK (Gaussian Minimum Shift Keying) modulation which introduces phase variations only. In UMTS, a WCDMA system with QPSK modulation is used where both phase and amplitude variations are introduced by the modulation. The power amplifiers designed for WCDMA need to satisfy the contradicting operation requirement between linearity and efficiency. In this thesis, a highly efficient class F power amplifier has been designed for WCDMA band with a center frequency of 2.14 GHz and bandwidth of 5 MHz using GaN transistor. The amplifier has been simulated using a high frequency circuit simulator namely, the Agilent Advanced Design System (ADS). The simulated results have shown a Power Added Efficiency (PAE) of 76.8% for an optimum input power of 30 dBm. The amplifier was then fabricated and measured. Measurement has shown a PAE of 75.9% for an optimum input power of 29.6 dBm which is in good accordance with the simulated results. Based on a literature review, and to the best of our knowledge, our circuit exhibited one of the highest measured PAE for a GaN class-F amplifier working at 2.14 GHz. The value of third and fifth order IM products of the designed class F PA is -13 dBc and -21 dBc respectively at peak power and -28.5 dBc and -43 dBc respectively at 6 dB back-off from peak power.
HLARTI based emergency preparedness and response training simulation

description: Many wake-up calls have been received for emergency response, due to natural disasters such as hurricanes, fires or man-made incidents, for example: oil and chemical spills, city bombings, and the terrorist attacks of 9-11. The emergency responders need to work in a coordinated, well-planned manner to best mitigate the impact of an emergency incident. Simulation systems as valuable tools provide a wider range of training at a much lower expense for emergency preparedness and response, and can be used for vulnerability assessment, organizing, educating and decision support. This is identified as the only feasible approach when it is difficult to emulate real-life experiences. This thesis presents an emergency evacuation training simulation, taking the demonstrative example of the SITE building of the University of Ottawa. The objective of the research is to design a multi-user distributed simulator to conduct the safety training in the scenarios of emergent evacuation. The real-time interaction and collaboration, in the simulation, among the users are achieved over HLA/RTI, the IEEE standard for distributed simulation and modeling.

description: The circular economy is anticipated to bring a disruptive transformation in manufacturing technologies. Robust and industrial scalable microbial strains that can simultaneously assimilate and valorize multiple carbon substrates are highly desirable, as waste bioresources contain substantial amounts of renewable and fermentable carbon, which is diverse. Lignocellulosic biomass (LCB) is identified as an inexhaustible and alternative resource to reduce global dependence on oil. Glucose, xylose, and arabinose are the major monomeric sugars in LCB. However, primary research has focused on the use of glucose. On the other hand, the valorization of pentose sugars, xylose, and arabinose, has been mainly overlooked, despite possible assimilation by vast microbial communities. The present review highlights the research efforts that have explicitly proven the suitability of arabinose as the starting feedstock for producing various chemical building blocks via biological routes. It begins by analyzing the availability of various arabinose-rich biorenewable sources that can serve as potential feedstocks for biorefineries. The subsequent section outlines the current understanding of arabinose metabolism, biochemical routes prevalent in prokaryotic and eukaryotic systems, and possible products that can be derived from this sugar. Further, currently, exemplar products from arabinose, including arabitol, 2,3-butanediol, 1,2,3-butanetriol, ethanol, lactic acid, and xylitol are discussed, which have been produced by native and non-native microbial strains using metabolic engineering and genome editing tools. The final section deals with the challenges and obstacles associated with arabinose-based production, followed by concluding remarks and prospects.

description: Environmental effects and natural resources depletion associated with agriculture production affect the agriculture response to climate change. Traditional cross-sectional climate response models ignore this requirement. This research estimates the impact of climate on European agriculture using a continental scale Ricardian analysis. We correct farm income by accounting for resources (energy, fertilizers, pesticides and water) use intensity by calculating the sustainable value for a sample of 9,497 specialized field crop farms across Europe. The results show that a uniform increase in temperature (+1°C) across all four seasons lead to significant and negative effects on farmland values, net revenue and farms’ sustainable value, while additional precipitation (+1 cm) across the all seasons increases farms' land values and sustainable values, and harms farms’ net revenue. Compared with the traditional Ricardian method, the marginal effect of 1° C increase in temperature shift from positive to negative in Northern countries, while it leads to less damages in Southern countries when net revenue and farms’ sustainable values are used as dependent variables. We demonstrate that accounting for the environmental effects and depletion of natural capital by agriculture significantly improves the ability of the Ricardian method to estimate agriculture climate response functions in the long run.
Intercultural mediation: Social, linguistic and psychometric considerations

Subjects: subject: Language, Linguistics.
subject: Psychology, General.

description: Educational research investigating second language (L2) learning proposes that interculturally competent individuals have the capacity to act as mediators during situations of conflict between members of distinct cultural communities (Alred & Byram, 2002; Gohard-Radenkovic, Lussier, Penz & Zarate, 2004). The following studies aim to systematically investigate this proposal. The first study examines the linkages between aspects of language learning (e.g., L2 contact and confidence) and the use of mediation behaviours among a sample of minority group members. The results indicate a general need for a strong first language identity in order to become involved as a mediator in a conflict scenario. However, the results also point to the need for further assessment of the measure of intercultural mediation. The second and third studies respond to this latter issue through use of modern and classical test theory approaches to instrument assessment among both majority and minority group members. In particular, the second study points to a need to distinguish between the status (minority vs. majority) of the groups involved in the conflict scenarios as well as whether members of the witness' in-group are perpetrating or victims of discrimination. Informed by the results of the second study, the third study outlines the development and assessment of a revised version of the Intercultural Mediation Measure. Following these assessments of the intercultural mediation measure, the final study explores the relative importance of status (minority vs. majority) and role (perpetrator vs. victim) in the prediction of intercultural mediation behaviours and the predictive capacity of first and second language attitudes and representations in the use of nondiscriminatory behaviours. Among a host of revealing results, the analyses indicated a trend of greater mediational involvement in conflict scenarios when the in-group is perpetrating the conflict toward a positively viewed outgroup. This research speaks to the capacity individuals have to demonstrate and encourage positive intercultural relations. The results are discussed in the context of L2 learning, intergroup theory, and directions for future research.

description: The purpose of this thesis is to study the temperature dependence of the electrical resistivity of the pseudo-binary (FexNi 1-x)77Si10B13 alloy system. The high precision four-wire electrical resistivity measuring method is used to obtain the resistance data of the samples from 2.1 K to 290 K. It is shown that the combination of quantum corrections, magnetic, and the thermal electron-phonon scattering contributions account for the temperature dependence of the electrical resistivity over the entire temperature range. The electron-electron interaction and the weak localization effects are dominant at low temperatures. At high temperatures, the mechanism of the electrical resistivity depends on the magnetic state of the alloy. When the sample is paramagnetic, the magnetic contribution is negligibly small and can be ignored in comparison to the contribution due to the structure factor. The magnetic contribution shows up at high temperatures at which the sample is ferromagnetic. The weak localization effects and electron-phonon scattering persist in high-temperature range. A good agreement between the fits and the experimental data are obtained in this study. The existing theories account well for the complexity of the temperature dependence of the electrical resistivity.
The impact of a resonance-based intervention on the cycling performance, well-being, and intrinsic motivation of endurance athletes

Subjects: subject: Health Sciences, Recreation.

description: The purpose of this study was to examine the process of resonance and overall experience of four endurance athletes participating in a 6-week resonance-based intervention. A second objective was to assess the impact of the intervention on the athletes' cycling performance, subjective well-being, and intrinsic motivation. This 16-week study was a multiple case, single-subject design comprising three phases: (1) a 5-week baseline period, (2) a 6-week resonance-based intervention period, and (3) a 5-week post-intervention period. The resonance-based intervention consisted of four in-depth, open-ended, and semi-structured interviews using the Resonance Performance Model (RPM. Newburg et al., 2002) as a framework and daily reflective journalling. The athletes also participated in a follow-up interview 5 weeks following the intervention to discuss whether or not they continued to apply resonance in their life and experienced any benefits from participating in the study. Measures of cycling performance, life satisfaction, positive and negative affect, and intrinsic motivation were taken twice weekly during the three phases of the study. Qualitative results were analyzed deductively based on the components of the RPM, whereas quantitative results were analyzed using the split-middle technique for single-subject designs. Although quantitative analyses provided mixed evidence for the value of the intervention, qualitative results showed that all four endurance athletes perceived that they enhanced their performance, well-being, and intrinsic motivation for both practices and races that occurred during the intervention. They also reported a significant increase in self-awareness, a positive change in focus from outcome to process, and an empowered ability to manage their emotional responses to events. Practical implications for using the RPM with athletes and other populations in exercise and health settings are discussed.

description: Cette thèse a pour objectif de déceler quels sont les critères d'une intégration réussie ressortant des discours tenus par des citoyens du Québec entre mars 2006 et décembre 2008 dans le cadre de l'émission de radio Maisonneuve en direct. L'ensemble des critères d'intégration y est traduit comme l'idéal du "bon" immigrant, soit une figure qui regroupe la somme des attentes issues de la présence d'alterité liée à l'immigration et qu'il est possible de retracer par l'utilisation inversée du concept de régime de citoyenneté (Jenson 1998). L'étude de la radio participative y est justifiée suivant la conception du public proposée par Michael Warner (2002), à situer dans une conception élargie de la sphère publique défendue par Iris Marion Young (2002). Les implications des représentations recensées sont évaluées par le biais de l'idéal de parité de participation de Nancy Fraser (2005) et de la contribution de Leonard Feldman (2004). Cela permet de conclure que quatre éléments ressortent des discours étudiés: (1) une définition procédurale de l'égalité, (2) une utilisation instrumentale de la laïcité, (3) une culture commune inaccessible et figée et (4) une absence presque totale de mentions de la participation des immigrants dans la société et dans la sphère politique.
Mentoring as part of a coach certification system
Creators: name: Cloutier, Robin A

Subjects: subject: Health Sciences, Recreation.

description: Canada's National Coaching Certification Program has been undergoing a re-structuring, resulting in a coaching education program that will be based more on enabling coaches to develop various coaching competencies, rather than on simply the teaching or provision of information that the coaches may or may not actually be able to implement with their athletes. In the sport of alpine skiing, for a coach to become certified within this new program, he or she must also participate in a mentoring process, where the focus is on the on-going learning of coaches. The mentoring process involves being mentored by a more experienced coach and having this mentor sign off on particular tasks over the course of the season. The purpose of the present study was to explore the learning process of two pairs of coaches in a formalized mentoring relationship within the context of a competitive alpine ski club, and to gain a better understanding of the interpersonal relationship between a coach and his or her mentor. Data were collected through in-depth interviews, field notes, and a series of on-hill observations. Findings from this study have indicated that (a) through the process of mentoring, coaches can become more reflective thinkers, (b) a clear separation of the mentoring process from the certification process is necessary, (c) the training session for the mentor evaluator coaches was a valuable learning opportunity, and (d) not only is mentoring a complex process with many facets but it also appears to be a personal dynamic and one mentoring relationship can be very different from another.
Best effort decontamination of networks
Creators: name: Qiu, Jun
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Computer Science.

description: In this thesis we consider the problem to find the optimal strategy to decontaminate the maximum possible number of nodes in a contaminated network with a fixed number of agents. We are given a team of mobile agents located on a node in a contaminated network and the number of agents is not enough to decontaminate the whole network to reach a state in which all nodes are simultaneously clean. We want to find what the maximum number of decontaminated nodes is and how to decontaminate them. In this thesis we consider meshes (regular, octagonal, and hexagonal) and trees and give optimal strategies for those topologies. We also analyze the performance of our strategies according to the number of decontaminated nodes, number of agents' movement and time.

Les médias et les politiciens occidentaux pendant la guerre en Irak: La persistance du mythe de l'Orient

description: Comment les rapports de pouvoir fonctionnent-ils et pourquoi sont-ils établis? C'est à travers les discours et les représentations qu'ils sont perpétués. L'orientalisme d'Edward W. Said est un exemple parfait de discours permettant plus particulièrement à l'Occident de dominer l'Orient. Pendant la guerre en Irak, il est d'ailleurs possible d'observer l'utilisation de ce discours dans le but de légitimer l'autorité occidentale sur ce pays. Selon Said, le discours et les représentations que l'Occident se fait de l'Orient déterminent ce dernier de façon impérialiste, mythique et réductrice. De plus, ce sont par les médias occidentaux que ces conceptions orientalistes sont véhiculées à travers le monde occidental, ces derniers jouant ainsi un rôle important dans la légitimation de ces actes de domination sur l'Orient auprès de la population. En s'appuyant sur la théorie orientaliste, cette étude cherchera à démontrer que les médias et les politiciens concernés utilisent un discours qui se fonde sur les représentations orientalistes, rendant ainsi légitime l'occupation de l'Irak.
Gallicisms: An analysis leading towards a prototype gallicisms checker.
Creators: name: Yuen, Adrienne L.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Language, Linguistics.

description: The anglicization of French has long been perceived as a major problem and much effort has been made both in France and in Canada to minimize its effects. The gallicization of English, though a problem of much smaller magnitude, has also been observed, particularly in areas such as Quebec where French is the dominant language. However, gallicization his received much less attention than anglicization. In fact, there seems to be little concern among Quebec's anglophones over the gallicization of English, which many do not perceive as being a problem. This lack of interest is not without potential consequences, for, as several linguists have noted, if the current trend towards "Frenglish" is not halted, the English of Quebec's anglo-phone minority may eventually become unintelligible to other English-speaking Canadians. This thesis studies gallicization and has two main objectives: to provide a theoretical and historical background to the phenomenon, and to create a prototype checker of gallicisms. The study includes: a discussion of interference, borrowing and gallicisms, including a definition of the term "gallicism"; a brief history of the English language in Canada with an emphasis on the various influences that have shaped Canadian English; a discussion of Quebec English and its distinguishing feature--gallicisms; a classification system of the different types of gallicism; a set of procedures for verifying suspected gallicisms; the results of an informal experiment where commercially-available tools were applied to a test document containing known gallicisms; a description of a prototype gallicisms checker.
Conceptualizing commitment to quality in an elementary school: Factor analysis of the effect of communication on employee attitudes and behaviours for Quality Management

description: Although the literature establishes the importance of employee commitment and communication, there is a lack of empirical research focusing on communication's precise role for Quality Management (QM). Within the context of change, this thesis demonstrates that communication contributes to commitment by targeting both attitudes and behaviours. These findings were used to build a content analysis identified communication initiatives within a school's QM program and an interview linked those initiatives to desired changes in attitudes and in behaviours to build an employee survey assessing communication and commitment. A factorial analysis revealed that three communication factors -- Involvement, Learning Culture and Formal Communication -- contributed to changes in both attitudes and behaviours suggesting that organizations can emphasize these factors in their communication plans to set the foundation for commitment to quality. This study focuses on the role of communication in creating commitment to quality specifically through attitudes and behaviours. Future research would be valuable in validating this model within other types of organizations.
