description: This qualitative autobiography explored the educational experiences of three adults who were bereaved in adolescence by the deaths of their fathers. Part of the purpose of this study is to make meaning of the school experiences of the participants after their fathers died. Three stories of bereavement are told to illuminate the needs of the participants at school. These needs are to communicate about their bereavement, to receive acknowledgement of their father's deaths and to feel affirmation from their peers. Data reveal that teachers and school personnel rarely addressed participants' needs. More could have been done to help the participants work through their bereavement while at school. For example, media such as art, literature, and music are explored in this study as means to work creatively with bereavement. These media are called sign systems, and are presented in this study as resources teachers can draw from to raise awareness of the human experience of bereavement. Suggestions for incorporating sign systems in the classroom setting are offered to integrate discussion about bereavement and grief with school curriculum. A Representation of Data Interpretation web is presented to illustrate the stories of the participants, and how three bereaved people work through bereavement together. The findings of this study suggest that bereavement is not a malady to be euphemized and covered up, rather, open communication about bereavement in the school setting can increase empathy and understanding about the lives of our fellow human beings: their struggles and successes.

description: We investigate the collective behavior of sterically interacting self-propelled particles confined in a harmonic potential. Our theoretical and numerical study unveils the emergence of distinctive collective polar organizations, revealing how different levels of interparticle torques and noise influence the system. The observed phases include the shear-banded vortex, where the system self organizes in two concentric bands rotating in opposite directions around the potential center; the uniform vortex, where the two bands merge into a close packed configurations rotating uniformly as a quasi-rigid body; and the orbiting polar state, characterized by parallel orientation vectors and the cluster revolving around the potential center, without rotation, as a rigid body. Intriguingly, at lower filling fractions, the vortex and polar phases merge into a single phase where the trapped cluster breaks into smaller polarized clusters, each one orbiting the potential center as a rigid body.

description: Genetic testing to determine whether a woman carries a BRCA1 or BRCA2 mutation, which may entail an up to 80% lifetime risk of developing breast cancer, is relatively recent. As there is an apparent void in the literature investigating the experiences of these women, and few qualitative studies of this nature exist, six women identified as carriers were invited to participate in semi-structured interviews. The grounded theory method was utilized and through findings emerged two core categories: Context Following the Receipt of the Test Results and Living with the BRCA Genetic Mutation: An Uncertain Conclusion to an Unending Process. Specifically, following the receipt of their test result, participants reported changes in their self-perception and perception of others. Over time, participants described living with the BRCA gene mutation and its medical consequences. Particularly significant findings consisted of participants feeling less like a woman, feeling stigmatized, and living with unending uncertainty.
The role of beta1 integrin in myelination and remyelination

Subjects: subject: Biology, Neuroscience.

description: Myelination is a process of cellular specialization, where oligodendrocytes in the central nervous system (CNS) undergo maturation to form the myelin sheath. Proper formation of the myelin sheath is an important process as it is responsible for rapid saltatory conduction along nerves and is required for the survival of the axons. Multiple Sclerosis (MS) is a disease that can be characterized by the degeneration of the myelin sheath within the CNS and the inability of the myelin sheath to reform. The damage or loss of myelin results in the disruption of impulses along nerve axons and ultimately leads to neurological symptoms. Therefore, it is critical to determine how oligodendrocytes develop and myelinate axons, and it is important we learn how to use this information to repair the lost or damaged myelin. Research is advancing our understanding of the various factors involved in oligodendrocyte development. In particular, much research has shown the importance of beta1 integrin in oligodendrocyte biology and in myelin membrane formation. We are the first to demonstrate in vivo that beta1 integrin is important in myelination and remyelination. With the use of the proteolipid protein promoter (PLP), we generated a transgenic mouse model that expresses the beta1 integrin subunit minus the cytoplasmic domain. This dominant-negative beta1 integrin mouse model is characterized by myelin defects in the optic nerve and spinal cord. Under the cuprizone-induced demyelination/remyelination model, the dominant-negative beta1 integrin mouse has delayed or impaired remyelination. We also show that the mitogen-activated protein kinase (MAPK) pathway appears to be important in beta1 integrin signaling during myelination and remyelination. Further analysis of the dominant-negative mouse model permitted us to get a better understanding of the role of beta1 integrin in oligodendrocyte development during remyelination. Our work demonstrates that beta1 integrin is important in the survival of oligodendrocytes acting primarily through the MAPK signaling pathway. Through the use of the dominant-negative beta1 integrin mouse model, we demonstrated in vivo the importance of beta1 integrin in myelination and remyelination, we furthered our understanding of beta1 integrin's role in the survival of oligodendrocyte development, and lastly we determined downstream signaling pathways that may contribute to the function of beta1 integrin in myelination and remyelination.

description: Cette recherche porte sur la cohérence intra, inter et extra des quatre réformes universitaires décidées au Congo-Zaïre en 1971, 1981, 1989 et 2003. L'analyse de la cohérence intra a cherché à savoir dans quelle mesure, pour chacun des 16 objets habituels des réformes académiques, chaque politique de ces quatre réformes se tient en elle-même. L'analyse de la cohérence inter a chérché à savoir dans quelle mesure chaque nouvelle réforme constituait, pour chacun des 16 objets, une amélioration des ratés et des insuffisances de la réforme précédente, et dans quelle mesure il y a eu une amélioration des politiques depuis la première jusqu'à la quatrième réforme. L'analyse de cohérence extra a cherché à savoir dans quelle mesure ces réformes ont été rigoureusement ancrées vis-à-vis de la trajectoire des besoins de développement de la société nationale. Pour y arriver, conformément à la méthode historique positive, nous avons procédé à une analyse de contenu des documents d'archives collectes au Congo Kinshasa. Mais face à la carence d'études et de modèles conceptuels sur l'analyse des cohérences intra, inter et extra des politiques d'Enseignement tertiaire, nous avons dû modifier et adapter des modèles conceptuels élaborés pour d'autres fins. Ces modèles, plus adaptés, sont : le modèle des 16 objets d'une réforme académique, le modèle de consistance et adéquation (cohérence intra), le modèle cyclique des politiques (cohérence inter), les modèles d'environnement scientifico-économique, social, politique, et culturel de l'Université (cohérence extra). Les résultats sur la cohérence intra montrent qu'à quelques exceptions près, les politiques alignent des stratégies inadéquates notamment quant à la prévision des ressources financières et humaines, et quant aux attitudes des agents de la mise en oeuvre. L'analyse de cohérence inter révèle entre les politiques analogues des réformes consécutives : l'abandon de problèmes non résolus, le non-suivi de résultats désastreux, et la réiteration d'inadéquations de stratégies. L'analyse de cohérence extra montre une absence de concordance entre l'évolution de la société en ses secteurs principaux et l'évolution de l'Enseignement tertiaire régie par les réformes. Par ricochet, l'étude révèle aussi la validité des modèles conceptuels employés dans l'analyse. La présente recherche est une réponse à une double pénurie : pénurie de recherche sur la cohésion, l'amélioration et l'insertion sociétale des politiques académiques du Congo-Zaïre; pénurie de recherche sur l'analyse de cohérence des politiques d'Enseignement tertiaire, et inexistence d'une tradition méthodologique relativement à ce champ des Sciences de l'éducation.

description: The main theme that I address in this paper is the boycott as a form of political solidarity. Recalling one of the primary objectives of Black and Third World feminist activists and scholars, I explore how BDS is one of the primary ways of building solidarity with Palestinians living under occupation. The logic of BDS is that of a unified, anti-racist and anti-colonial politics, which counters the logic of the Oslo Accords, one of fragmentation along multiple axes.

Impressions of 'Newness' in English Canadian Theatre The role of festivals in the consecration and distribution of new work

Subjects: subject: Theater.

description: In English Canadian theatre, there exists a significant divide between established works produced in the mainstream and new work that has traditionally been relegated to the margins of institutional practice. Seeking to bridge this divide are a number of festivals committed to fostering and showcasing plays by Canadian theatre artists and companies and to attracting presenters interested in programming new works for future seasons. In order to succeed in the festival circuit, independent companies must, to a certain extent, cater to the expectations of organizations that value performance that gives the impression of being novel and yet proves accessible to festival audiences and to those targeted by presenters. This plays a role in aesthetics that become characteristic of the companies' work. These aesthetics are not only accepted, but also exploited by festivals that are seeking to legitimize the notion of 'newness', in part, for the purpose of their own sustainability.
Bilingual today, united tomorrow: Canadian federalism and the development of the Official Languages in Education Program, 1968--1984
Creators: name: Hayday, Matthew
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2003
Subjects: subject: History, Canadian.

description: The language policies adopted by the government of Pierre Elliott Trudeau have been widely criticized within the political science community. This criticism is rooted in the failure of these policies to promote a Canadian identity rooted in a French Quebec-English Canada duality, as demanded by Quebec nationalists. A closer examination of the development of these language policies, particularly as they pertain to education programs, suggests a revised interpretation. Far from being a failure, the Canadian government's Official Languages in Education Program (OLEP), launched in 1970, threw a lifeline to French-Canadian and Acadian minority communities, developing their minority language education systems, and providing them with much-needed time and funds to regroup, after they lost the traditional supports of the Catholic Church and the Quebec government. To promote individual bilingualism, the OLEP's second language initiatives led to significant expansion of French second language instruction, and the proliferation of French immersion programs. Through its support to provincial education systems, the OLEP also laid the groundwork for section 23 of the Canadian Charter of Rights and Freedoms, which guaranteed minority official language education rights. Drawing primarily on archival materials from six provinces (Alberta, Manitoba, Ontario, Quebec, New Brunswick and Nova Scotia), the federal government, and a host of lobby groups involved in the process, as well as interviews with a number of key civil servants, politicians and lobbyists, this thesis reconstructs Ottawa's strategy to promote official languages in education. It shows how the OLEP, a program designed primarily by the Canadian government and implemented by the provinces, was shaped by debates over the nature of the Canadian federal system. Initially designed as an intrastate program, a concerted drive for more provincial autonomy in the 1970s (and a concomitant interstate vision of Canadian federalism) threatened Ottawa's control over the direction of the OLEP. Through a combination of pressure applied by the embedded state, via supportive lobby groups and civil servants, and a concerted constitutional strategy, the Canadian government was able to rebalance the forces of intrastate and interstate federalism, defend its vision of a pan-Canadian English-French linguistic duality, combat Quebec separatism, and instil official bilingualism into the discourse of Canadian identity.
Neural dynamics leading to optimized information transfer

description: Neural information processing by trains of action potentials is studied in the context of weakly electric fish electroreceptor neurons. A simple but accurate dynamical model for the firing activity of these neurons is presented and compared with experimental results. Dynamical analysis of the model reveals the mechanism by which it reproduces features present in experimental data, such as relative refractoriness and bursting behaviour. Approximations necessary for application of information theory to neural spike trains are presented and different measures are compared. Finally, the consequences of spike patterning caused by relative refractoriness and bursting on information transfer are investigated. It is found that relative refractoriness can increase information transfer while bursting provides a non-linear mechanism for encoding information that might be more efficient than firing of isolated spikes.

description: Integrative healthcare (IHC), the combination of biomedical disciplines and expertise in various forms of complementary and alternative medicine (CAM), is an example of interdisciplinary collaboration that has emerged over the last two decades. Little has been written so far to gain an understanding of how the healthcare practitioners in such setting collaborate. The main goal of this doctoral dissertation was to better understand what is inside the "black box" of interdisciplinary collaboration within IHC clinics so that appropriate links related to clinic effectiveness and cost-effectiveness as well as patient outcomes could be tested in future research. This thesis explored the concept of interprofessional collaboration in IHC using three theoretical and conceptual models: Input Process Output, Relationship-Centered Care, and Models of Team Healthcare Practice. Inductive and deductive inquiries were conducted through sequential mixed methods and methodological triangulation techniques. Four objectives were proposed to better understand how collaboration was experienced and conceptualized within these clinics and how the related factors interacted with each others. Finally, assumptions of a conceptual model of classification of IHC clinics were tested. Constructs contributing to collaboration included practitioners' attitudes and educational background, as well as external factors such as the healthcare system and financial pressures. Major processes affecting collaboration consisted in communication, patient referral and power relationships. These determinants of collaboration resulted in learning opportunities for practitioners, modified burden of work and ultimately, higher affective commitment toward the clinic. The quantitative inquiry revealed that interpersonal relationships were shown to be central to the collaborative practice of IHC delivery. Additionally, beliefs in the benefits of collaboration were found to play an important role in an IHC collaborative enterprise. Finally, clinic model comparisons confirmed that interprofessional collaboration is modulated by the practice model. Suggestions to improve the conceptual model of classification were made. This multi-method study was the first to summarize systematically the factors that impact and ensue from interprofessional collaboration in the context of Canadian IHC. The framework lay down by this dissertation represents an important step to investigate further the impact of IHC on patients and the Canadian healthcare system and to guide the development of more effective IHC clinics.

description: In a context of great technological and social change, existing intellectual property regimes such as copyright must contend with parallel forms of ownership and distribution. Proponents of open access, for example, question and undermine the paradigm of exclusivity central to traditional copyright law, thereby fundamentally challenging its ownership structures and the publishing practices these support. In this essay, we attempt to show what it is about the open access endeavour that resonates with a feminist theory of law and society—in other words, we consider what is “feminist” about open access. First, we provide an overview of a relational feminist critique of traditional copyright law and the assumptions of possessive individualism that pervade it. We then offer a brief description of the open access movement and the way in which it reflects or responds to this criticism. In doing so, we discover vital synergies between this branch of feminist legal theory and the open access movement. Ultimately, we hope to underscore the importance of an open access policy for legal journals such as this one, whose mission is to support, advance and disseminate a feminist perspective that challenges the prevailing hegemony within traditional legal scholarship. We conclude by offering ways in which this journal can help draw out the synergies between feminist criticism and the open access movement.

Year: 2009
Subjects: subject: Mathematics.

description: An H-decomposition of a graph G is a partition of the edges of G into subsets, each of which induces a graph isomorphic to H. In this thesis, we will study decompositions of certain graphs into cycles and closed trails. In particular, we consider decompositions of complete multigraphs and complete equipartite graphs. The complete multigraph lambdaKm is the multigraph with m vertices and lambda edges between each pair of vertices. The complete equipartite graph Km * Kn with m parts of size n is the simple graph on mn vertices, such that the vertices are partitioned into m parts of size n, and two vertices are adjacent if and only if they are in different parts. With regard to closed trail decompositions, we find necessary and sufficient conditions for the existence of a decomposition of the complete equipartite graph Km * Kn into closed trails of length k. We then turn our attention to cycle decompositions, and give necessary and sufficient conditions for the existence of a decomposition of the complete multigraph 3 Km into cycles of odd length k ≠ 9. We then show how to use this result to construct k-cycle decompositions of Km * K3 when k = 9k', where k'| &parl0;m2&parr0; and k' > 3. In addition, we discuss other cases in which decompositions of Km * K3 into k-cycles can be found.

description: The formulation of quarkyonic matter consists of treating both quarks and nucleons as quasi-particles, where a cross-over transition occurs between the two phases. This work is based upon some of the early ideas of quark matter. It can satisfy the different observational constraints on the neutron star (NS), such as its maximum mass and the canonical radius. In addition, we put an extra component inside the NS known as Dark Matter (DM) because it is trapped due to its immense gravitational potential. In this work, we explore the impact of fermionic DM on the structure of the NS. The equation of state (EOS) is derived for the NS with the quarkyonic matter by assuming that nucleons and quarks are in equilibrium, followed by the relativistic mean-field (RMF) formalism. The recently modeled two parameterizations, such as G3 and IOPB-I, are taken to calculate the various macroscopic properties of the NS. The three unknown parameters such as the transition density ($n_t$), the QCD confinement scale ($Λ_{\rm sc}$), and the DM Fermi momentum ($k_f^{\rm DM}$) are varied to obtain the NS properties. The quarkyonic matter stiffens the EOS while DM softens it. The mutual combination provides us with good theoretical predictions for the magnitude of macroscopic properties consistent with the different observational results. Also, one can estimate the parameters of the DM admixed quarkyonic star with different statistical analyses, which can be further used to explore the other properties of the quarkyonic star.

Questions and Focus in Bulgarian

Year: 2010
Subjects: subject: Language, Linguistics.

description: This dissertation proposes a unified approach to the study of interrogatives in Bulgarian based on experimental data on wh- and yes/no interrogatives and on the semantic analysis of polar questions. It investigates the hierarchy of wh-words, the syntactic structure of interrogatives, the semantics of polar questions and the connection between focus and questions in general. The experimental part of this dissertation reports on two grammaticality judgment tasks. It is argued that (a) wh-movement is an instance of focus movement; (b) only the highest animate element is further raised to SpecCP; and (c) in addition to superiority, an animacy-based hierarchy is critical in wh-ordering in Bulgarian. The experimental data adds a new dimension to the ongoing debate concerning the types of functional categories required in the left edge of the clause, suggesting that in Bulgarian there is a need for at least two syntactic projections related to wh-movement of non-d-linked wh-elements, Focus Phrase and Complementizer Phrase. The semantic part of the dissertation is dedicated to the interpretation of polar interrogatives in Bulgarian and their close relation to focus. I assume that the interrogative particle li heads the clause-internal focus projection, whereas the interrogative word dali is a true interrogative complementizer. Thus, dali-questions parallel English polar interrogatives, whereas li-questions are focus-dependent and their interpretation is always related to the contextually restricted set of alternatives evoked by focus. Two types of question operators are proposed. First, dali is equivalent to the silent question operator Q in English. Second, li is a focus-dependent question operator (QF) which combines with the contextually-restricted set of alternatives. This dissertation brings new evidence confirming the long discussed connection between interrogative words and focus. In constituent questions, this relation is reflected in that wh-words move to SpecFocP. In polar questions, the effect of focus is manifested in their focus-dependent semantics. This work shows that there is an important parallel between polar and constituent questions, and that focus-sensitive operators, particles, and adverbs function similarly across different languages. Thus, this dissertation argues in favour of the possibility that focus-dependency is a general property of interrogatives in Universal Grammar.

description: CSR may be a means of dealing with human rights abuses and negative environmental and socio-economic impacts associated with mining in developing nations. Little research has been published on how "host" and "home" governments can help make CSR initiatives in this industry more effective. This study obtained perspectives on their roles through a study of the academic and secondary literature on CSR and its application in exploration and mining. Four literature case studies of exploration projects and mines in Peru (Tambogrande, Tintaya, Rio Blanco, and Antamina) were followed up with field studies of the Rio Blanco project and Antamina mine through interviews with community members, authorities at various levels of government, NGOs and industry representatives. The study showed the effect of mining cycle stage and regional differences on dynamics, power relations, and perspectives; and the importance of governments as players. It presents a list of options for their action.

description: Recent releases of pre-trained Large Language Models (LLMs) have gained considerable traction, yet research on fine-tuning and employing domain-specific LLMs remains scarce. This study investigates approaches for fine-tuning and leveraging domain-specific LLMs, highlighting trends in LLMs, foundational models, and methods for domain-specific pre-training. Focusing on the financial sector, it details dataset selection, preprocessing, model choice, and considerations crucial for LLM fine-tuning in finance. Addressing the unique characteristics of financial data, the study explores the construction of domain-specific vocabularies and considerations for security and regulatory compliance. In the practical application of LLM fine-tuning, the study outlines the procedure and implementation for generating domain-specific LLMs in finance. Various financial cases, including stock price prediction, sentiment analysis of financial news, automated document processing, research, information extraction, and customer service enhancement, are exemplified. The study explores the potential of LLMs in the financial domain, identifies limitations, and proposes directions for improvement, contributing valuable insights for future research. Ultimately, it advances natural language processing technology in business, suggesting proactive LLM utilization in financial services across industries.

description: Née dans le secteur de l'informatique au milieu des années 1980, la localisation est devenue une véritable industrie au début des années 1990. Les milieux de la traduction et de la traductologie ont commencé à s'y intéresser vers la fin des années 1990, intérêt qui semble avoir provoqué un débat sur le sens du terme localisation. Mais, aujourd'hui, savons-nous à quoi renvoie précisément le concpt de localisation? L'objectif de la présente thèse est de proposer une réflexion sur le concept de localisation afin de tenter de le désambiguiser. Nous commençons par faire l'historique de l'industrie de la localisation, présenter la localisation en tant que processus multidisciplinaire et examiner l'emploi du terme localisation. Puis, pour vérifier notre hypothèse selon lauelle l'ambiguité du concept vient du fait que la localisation est un concept multidisciplinaire, nous précédons à l'analyse de définitions et de contextes définitoires tirés de diverses sources, analyse qui met l'accent sur l'objet de la localisation, à savoir la nature du produit localisé. Les définitions et contextes sont regroupés en fonction du domaine d'activité des auteurs qui les ont formulés, de façon à mettre en lumière les différences ou ressemblances entre les specialistes des divers domaines d'activité en lien avec la localisation. L'analyse des définitions et des contextes effectuée permet de constater que les spécialistes des divers domaines d'activité ne s'entendent toujours pas sur le sens du terme localisation. Le concept de localisation demeure flou et ambigu, particulièrement en ce qui a trait à la nature du produit localisé.
In vitro connexin expression and function in postnatal neural progenitors
Creators: name: Gauvin, Lianne G
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Chemistry, Biochemistry.

description: The studies presented in this thesis were performed to gain insight into the role of connexins (Cxs) and Cx-mediated communication in regulating postnatal neural precursor cell (NPC) fate. Cxs are protein subunits that oligomerize into hexamers to form hemichannels, permitting the passage of molecules between the cytoplasm and the extracellular space. Docking of two hemichannels elaborated by adjacent cells form a single gap junction channel allowing direct cell-cell communication. Here, I hypothesized that Cx-mediated gap junctions and open hemichannels in nonjunctional membranes represent two robust signalling mechanisms by which NPCs may communicate with neighbouring instructive cells and the extracellular environment. In Chapter 2 of this thesis, I show that Cx26, Cx29, Cx30, Cx37, Cx40, Cx43, Cx45 and Cx47 mRNA and protein but only Cx32 and Cx36 mRNA are expressed by primary postnatal hippocampal precursor cells grown as neurospheres. The specificity of immunodetection was confirmed using cultures derived from null-mutant mice controls. I also found that culture conditions affect Cx expression and that the repertoire of Cxs expressed by NPCs changes over the course of differentiation in vitro. NPCs grown as monolayers on laminin-coated coverslips expressed Cx26, Cx29, Cx30, Cx36, Cx37, Cx40, Cx43 and Cx45 protein but not Cx32 and Cx47. Every Cx protein examined except Cx32 was found in discrete cell lineages following differentiation to neuronal and glial lineages. In Chapter 3, a series of dye uptake assays were performed that established inducible hemichannel activity in NPCs cultured as adherent neurospheres. I found that this hemichannel activity was lost when neurosphere-derived cells were maintained as proliferating monolayers or induced to differentiate. Conversely, functional gap junction biochemical coupling, as assessed by passage of the anionic dye lucifer yellow, increased following differentiation. Finally, one Cx (Cx29) was chosen to assess the impact of altering Cx expression on NPC fate. In Chapter 4, Cx29 null-mutation was found to reduce spontaneous astrocytic differentiation following growth factor withdrawal. Together, these observations provide further support for the hypothesis that the repertoire of Cx proteins dictates, in part, a progenitor cell's intrinsic capacity to respond to its microenvironment.
Large-eddy simulation (two-dimensional) of spatially developing mixing layer using vortex-in-cell for flow field and filtered density function for scalar field

description: A Large Eddy Simulation (LES) based on filtered vorticity transport equation formulated using diffusion-velocity method and discrete vortex method has been coupled to filtered density function (FDF) equation for scalar, to predict the velocity and passive scalar field of a spatially developing mixing layer. In the vortex method, the vorticity-based and eddy-viscosity type subgrid scale (SGS) model simulating the enstrophy transfer between the large and small scale appears as a convective term in the diffusion-velocity formulation. The methodology has been tested on a spatially growing mixing layer using the two-dimensional vortex-in-cell method with both Smagorinsky and Dynamic Eddy Viscosity subgrid scale models for an anisotropic flow. The effects on the vorticity contours, momentum thickness, streamwise mean velocity profiles, root-mean-square velocity and vorticity fluctuations and negative cross-stream correlation are discussed. Comparison is made with experimental and numerical works where diffusion is simulated using random walk. The transport equation for FDF is solved using the Lagrangian Monte Carlo method scheme. The unsolved subgrid scale convective term in FDF equation is modeled using the conventional gradient diffusion model for an anisotropic flow. The subgrid scalar mixing term is modelled using the Modified Curl model. The characteristics of the passive scalar, i.e., mean concentration, root-mean-square concentration fluctuation profiles and probability density function (PDF) are presented and compared with previous numerical and experimental works. The sensitivity of results to SGS model, Schmidt number, constant in mixing frequency and inlet boundary condition is discussed.

description: This thesis describes the development of a curriculum for a prenatal breastfeeding workshop and the randomized controlled trial that was completed to test the hypotheses that the workshop would have a positive influence on maternal breastfeeding self-efficacy and that increased self-efficacy would positively affect breastfeeding duration. Breastfeeding self-efficacy, measured with the Breastfeeding Self-Efficacy Scale-Short Form, and breastfeeding duration, recorded as number of days and amount of breastfeeding, were measured at 4 and 8 weeks postpartum. The results of this study suggest that the prenatal breastfeeding workshop had a positive effect on maternal breastfeeding self-efficacy and on the amount women were breastfeeding. Over time, maternal breastfeeding self-efficacy scores increased in both groups with the intervention group having higher scores. At week 4, there was a significant difference in scores (control, M = 53.38 (SD = 9.1); intervention, M = 57.98 (SD = 8.6), t(78) = -2.32, p = .023, d = .523, CI -8.53, -0.65) At week 8, there was a difference in scores, but given the small sample size, these were not statistically significant (control, M = 58.91 (SD = 9.1); intervention, M = 61.70 (SD = 5.8), t(72) = -1.60, p = .115, d = .412). Although there was little difference between the groups in the number of days of breastfeeding, the intervention group had more exclusive breastfeeding (70% vs. 58%) and less weaning (15% vs. 22%) when compared with the control group. The most common reason for weaning was insufficient milk supply. (Abstract shortened by UMI.)
Revisiting Feminist Jurisprudence: A Rehabilitation
Creators: name: Drakopoulou, Maria
Publisher: name: feminists@law

description: This paper seeks to revive feminist interest in jurisprudence. However, it does not do so by conducting a historical inquiry designed to restore forgotten female jurists or reveal women’s contributions to the jurisprudential tradition. Instead, it comprises an invitation to rethink the encounter of jurisprudence with feminism. To this end it considers what counts as feminist jurisprudence, situating the rise of legal scholarship that defines itself as such, and setting out the notion of positionality as the criterion to judge what else can be included under this label. Thereafter it discusses the distinctive strands of what I deem to be feminist jurisprudence, before concluding with a call for a feminist re-imagining of jurisprudence as an activity both theoretical and pragmatic, and also as one which might hold hitherto un-thought possibilities for a feminist analysis and critique of law.

A framework for long-term preservation of multiple relational databases
Creators: name: Wang, Bo
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Computer Science.

description: With the advancement of information technology, more and more information is stored in digital format. Along with the evolution of computer science and its related technologies, new hardware and software emerge every day. At the same time, old hardware and software become obsolete and the data on them become inaccessible. Therefore, the development of environments to preserve digital data for the long-term (such as 50 years) has become a critical issue. This thesis focuses on how to preserve data in multiple databases for a very long time. A framework is proposed to provide a platform for archiving and retrieving the data in persistent databases. Within this framework, a multi-agent system is used to deal with the scalability and evolution of the data. An experimental environment is developed to validate the framework and to provide a base for further research. Since there is a lack of universally accepted methods to prove the success of a long-term data preservation repository, we combine theoretical proof and empirical confirmation together to address this issue.

Thinking skill development in the context of a mainstream subject area.
Creators: name: Taylor, K. Lynn.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Education, Curriculum and Instruction.

description: University teaching and learning experiences which are characterized as unsatisfactory by many faculty and students can be more precisely defined as manifestations of poorly developed higher order thinking skills. Two hypotheses relevant to this problem are explored in this thesis. The first is that it is possible to use the characteristics of good and poor problem solvers documented in the literature as a productive way of recognizing and understanding the learning problems experienced by many university students. The second hypothesis is that the integration of the characteristics of effective problem solvers into a framework of general problem solving heuristics is a practical and effective strategy to move students along a continuum to better developed higher order thinking skills within the broader context of knowledge acquisition. The teaching strategy developed from the literature and illustrated in a case study, is designed to capitalize on the scholarship of faculty often underutilized in their teaching, by encouraging faculty to be more self-conscious in making process skills explicit in a way that is meaningful to their students. As demonstrated in the case study, it is a strategy which utilizes teaching opportunities and data sources available in the classroom situation. The results of the case study indicated that, in this case: (1) characteristics of good and poor problem solvers were observable in the classroom situation; (2) faculty could learn and use the strategy effectively in the context of discipline teaching; (3) the strategy did not seriously restrict the amount of content to be taught; (4) students did acquire skills specific to the strategy implemented; and (5) that particular areas of concern for further applications were encouraging students to actively engage in process tasks, to have more confidence in their use of reasoning as a tool and to place more emphasis on the cognitive skill of evaluation.
A public key-based encryptiondecryption technique for real-time signals
Creators: name: Zhao, Rui
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Engineering, System Science.

description: Pay-TV Satellite Broadcast Service is very common today. However, protecting signals from being pirated is a principal issue. That is done using a conditional access system. In this thesis, we introduce and analyze different existing conditional access system design methods. Modification of the current method is proposed, and significant performance improvement is obtained. Satellite communication and cryptology are studied theoretically, which enables us to design public key-based encryption/decryption techniques for satellite broadcast that can supply higher secret solutions. Our simulation results show that the new design system is superior and more practical.
Hume on dreams and reality
Creators: name: Miller, Jon Charles
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Philosophy.

description: I first outline the controversy surrounding Hume's ontology which is essentially the question: is Hume a realist or an idealist? The realists or 'New Humeans' claim that Hume's natural beliefs allow one to have confidence that there is an external world of objects in causal relation even though reason shows this belief to be unfounded. They further argue that one can form relative ideas of the external world. Finally they claim that evidence for this interpretation is found mostly in the Enquiry, thus they argue that the latter text is superior to the Treatise. The idealists claim that Hume is at base a radical sceptic who if he has any ontological commitments they are the idealist assertion that only perceptions exist. They also tend to favour the Treatise over the Enquiry. After providing a critical overview of both of these arguments, which also includes the question regarding Hume's alleged projectivism, I then show how the analysis of dreams in Hume's empiricism breaks the stalemate that has occurred in this controversy surrounding Hume's ontology. I show that the natural belief in dreams points the argument towards an idealist interpretation of Hume. In the concluding section I summarize the findings of the dissertation and provide answers to some anticipated objections.
Chick talk: (de)constructing chick lit and women's fiction
Creators: name: Croker, Carol-Anne
Publisher: name: Swinburne

description: Women authors are accepted as valued (marketable) contributors to genre fiction and they are welcome to even subvert the tropes associated with these genres, thus we have a long established practice of narratives featuring female forensic investigators and private eyes, and female warriors in sci-fi and fantasy. Yet the women writing in the genre ‘chick lit’ are dismissed by the literary elite as ‘not real authors’ churning out contemporary versions of the ‘bodice ripper’. What I am attempting to discover in this paper is the elements that explain the popularity in the market of the ‘chick lit’ novel throughout western cultures. It is my contention in this paper that the phenomenon dubbed ‘chick lit’ is actually the mobilization of a backlash against the destruction of, and criticism directed towards the male literary hegemony. By looking at the fastest selling genres of women’s fiction I will attempt to answer this question as to if this is in fact a global phenomenon.
