Cardiac rehabilitation for aerobic training in individuals post-stroke

Aerobic capacity is often compromised in the post-stroke population, which can limit function and potentially increase subsequent stroke risk. In spite of the possible benefits of aerobic training in this population, appropriate programs are rare. The purpose of this thesis was to investigate the potential use of an existing program, cardiac rehabilitation, to provide post-stroke aerobic training. The potential availability of cardiac rehabilitation for this population was investigated using a survey of cardiac rehabilitation facilities in Ontario (n=47). Over half of respondents accepted some individuals post-stroke; however, potential barriers appeared to exist that limited enrollment. The potential effects of cardiac rehabilitation were investigated by enrolling individuals (n=27) into an existing cardiac rehabilitation program. Participation resulted in an improvement in aerobic capacity (32% increase in VO2 peak) and functional walking (11% increase in 6 minute walk time). This work has important implications for the health and function of individuals post-stroke.
Practitioners' experienced knowledge: creating space for understanding in cross-cultural clinical practice

The need to develop a deep and profound understanding of the worldview or cultural frame of reference of the other is an axiom of multicultural practice, but clinical processes for facilitating this kind of understanding seldom have been the focus of clinical practice research. The current study seeks to address this gap. The study is located in a reflective practice paradigm and takes the position that a rich source for professional knowledge building is the experienced knowledge of practitioners. The study utilizes an interpretive research design and a novel method of in-depth reflective inquiry to access and analyze the experienced knowledge of a purposive sample of frontline practitioners, and then examines how this knowledge interfaces with the formal knowledge of the profession. Intensive, iterative analysis of the emergent themes culminated in an integrative conceptual model entitled Creating Space for Understanding in the Context of Complexity. Highly nuanced clinical processes of inquiring, interpreting, implementing and improvising emerged as interwoven aspects of the overarching process of creating shared space for the mutual exploration of meaning and the dialogical negotiation of shared understanding. The study findings contribute to an expanded understanding of culturally competent practice by shifting the focus from what practitioners need to understand to how they go about understanding in contexts where there are pluralist standpoints, diverse meanings, and divergent frames of reference. In this context of diversity and complexity, interpretive, hermeneutic, and collaborative capacities emerged as core competencies, including the capacity to tolerate uncertainty, to inquire reflexively, to think critically, and to engage interpretively in an inductive, contextualized, improvisational, and dialogical process of co-creating mutual understanding and meaning. In addition to the substantive findings, the study makes a distinct contribution to the field of clinical practice research by demonstrating how reflective inquiry processes can be incorporated into interpretive research designs in order to access, analyze, and make available to the profession the experienced knowledge of practitioners. The findings represent research-based practice knowledge that is grounded in the lived experience of frontline practice in the context of vast social and cultural diversity.
Language, writing, comments and trauma: resisting the spiritual wound in academic life

Entering the academy as an adult, working-class student in a program that prepared me for university, and subsequently as an undergraduate student, challenged me in many ways, especially in learning how to write in the language of the academy. Employing an arts-based and auto-ethnographic approach, I discuss some of my experiences in the academy, drawing attention to language usage in expository writing while focusing on written wounding comments from teaching assistants on my marked papers. This thesis reveals how teaching assistants' written comments can wound and traumatize students, injuring their spirit. This work raises awareness about how story-telling can also help build self-confidence, can empower and can foster peaceful environments that enable students to heal and recover academically from invisible wounds. It also shows how students may gain spiritual strength for academic success to solve and respond to trauma in the academy. The learning objectives are to share my story, extend the discussion to a critique of the academy, and to point to broader questions of students' resistance and survival in the academy.
The parent-child relationship and parents' involvement in youth justice proceedings from the perspective of youth: A pilot study

The Canadian Youth Criminal Justice Act recognizes the important role of parents in young people's legal proceedings. Yet, there has been little empirical research on the predictors of parental involvement in the youth justice system. In the present study, 47 male young offenders were interviewed about their experiences with parents prior to and during judicial proceedings, to examine the factors associated with young people's perceptions of parental involvement in legal contexts. Results indicated that parental warmth and general involvement in a young person's life were significantly related to parental participation in the youth justice system. However, multiple regression analyses showed that parental warmth offered little additional predictive power beyond that contributed by parents' general involvement. Findings are discussed in terms of both theoretical and practical implications, and directions for future research are outlined.

Amido-hydrido complexes of ruthenium and osmium: Reactivity and their use in catalysis

The new air-sensitive ruthenium and osmium amido-hydrido complexes RuH(NHCMe 2CMe2NH2)(PPh3)2 and OsH(NHCMe 2CMe2NH2)(PPh3)2 have been synthesized and characterized. The hydrogenation of ketones to alcohols using these catalysts was explored. This included exploring the reactivity of these complexes toward hydrogen gas, ketones and alcohols, as well as performing kinetic experiments. The behaviour of the ruthenium and osmium systems were compared and mechanisms were proposed. Density functional calculations were carried out to model the proposed mechanisms and these were compared with experimental results. RuH(NHCMe2CMe2NH2)(PPh 3)2 was reacted with formic acid to generate RuH(OCHO)(NH 2CMe2CMe2NH2)(PPh3) 2, a model compound for the transfer of hydrogen from ruthenium to a ketone. The reactivity of the amido complexes towards weakly acidic compounds, HX, to generate new diamino complexes of the type MHX(NH2CMe 2CMe2NH2)(PPh3)2 (M = Ru or Os, X = H, OPh, NCCHCN, CH(COOMe)2, CCPh, OPPh2, OP(OEt)2, p-SC6H4OMe) was explored. Useful correlations were drawn relating the effect that the ligand trans to hydride has on the NMR and infrared spectra of these compounds. The complex RuH(OPh)(NH 2CMe2CMe2NH2)(PPh3) 2 hydrogen bonds with an equivalent of phenol to generate RuH(OPh···HOPh)(NH 2CMe2CMe2NH2)(PPh3) 2, which contains an interesting 6-membered ring as a result. This structure is similar to the proposed transition state for the alcohol-assisted splitting of dihydrogen by OsH(NHCMe2CMe2NH2)(PPh 3)2. The novel ruthenium complexes RuHX(1,2-NH2C 6H10NH2)(PPh3)2 (X = OPh, NCCHCN, CCPh, OPPh2, OP(OEt)2, p-SC6H 4OMe) were generated from the reaction of RuHCl(1,2-NH2C 6H10NH2)(PPh3)2 with HX and base. The complexes RuH(CCPh)(diamine)(PPh3)2 (diamine = NH2CMe2CMe2NH2 or 1,2-NH 2C6H10NH2) catalyze the hydrogenation of acetophenone to 1-phenylethanol, but less efficiently than the amido complexes. The complexes MH(CH(COOMe)2)(NH2CMe2CMe 2NH2)(PPh3)2 (M = Ru or Os) and the amido complexes also catalyze the Michael addition of dimethylmalonate to 2-cyclohexen-1-one. The reaction of RuH(NCCHCN)(NH2CMe2CMe 2NH2)(PPh3)2 with 2-cyclohexen-1-one leads to the formation of the trapped Michael adduct RuH(NCC(C6H 9O)CN)(NH2CMe2CMe2NH2)(PPh 3)2. The structure of this complex was used in proposing a mechanism for Michael addition reactions catalyzed by the amido complexes. The relative reactivity and strength of the osmium and ruthenium amido bonds were investigated through a series of competition experiments where HX (X = Cl, OPh, NCCHCN, p-SC6H4OMe) was transferred from OsHX(NH2CMe2CMe2NH2)(PPh 3)2 to RuH(NHCMe2CMe2NH2)(PPh 3)2 leading to RuHX(NH2CMe2CMe 2NH2)(PPh3)2 and OsH(NHCMe2CMe 2NH2)(PPh3)2.
The parenting experience of adults with learning disabilities

This research reports on parents with learning disabilities. This qualitative investigation focused primarily on participants' perceptions of the impact of their learning disability on their experience of parenting. The existence of a learning disability was validated using recent psychoeducational assessment results, or with a brief psychoeducational assessment administered by the researcher. Fifteen participants engaged in two in-depth interviews with the researcher. In the second interview, each participant responded to the researcher's initial summary of the themes and patterns emerging from their individual, and the group's initial, interviews. The thesis begins with an overview of the status of research focusing on adults with learning disabilities, research on parents with disabilities, and the need for, and possible benefits of, an inquiry into the largely unexamined linkages between these areas of study. Little is known about the parenting experiences of adults with learning disabilities, about the strategies they have found helpful in carrying out their parenting activities, and the recommendations they have for other parents in a similar situation or for those who work with such parents. The findings reveal several problematic areas for these parents, in addition to many positive characteristics that they demonstrate in their parenting. Emergent themes centred around the protectiveness that participants felt concerning their children's self-esteem as well as their academic success, difficulties participants experienced in terms of time management, participants' emotional reactions to their experience of having a learning disability (such as feelings of inadequacy, guilt, regret, and frustration, as well as an emphasis on being self-reliant), and the importance that participants ascribed to having self-knowledge about their learning disability. Participants' reported experiences suggested that the learning disabilities led to a pervasive sense of vulnerability regarding the negative impact of the disability on many aspects of their lives, including their parenting experience. Study findings, while consistent in many respects with Belsky's (1984) Process Model of the Determinants of Parenting, lead to a revision of this model to include this sense of vulnerability as an intrinsic part of the Personality determinant and to suggest bi-directionality of effect between some of the determinants.

Regulatory hierarchies in auxin signal transduction and vascular tissue development

The vascular tissues in plants form a continuous network of cell files throughout the plant body (Esau, 1965). The mechanisms and regulatory hierarchies that lead to its localized differentiation are just beginning to be understood. Several lines of evidence including experiments of direct auxin application, auxin transport inhibition and mutants with compromised auxin perception, suggest a role of auxin in vascular differentiation. In addition, auxin can induce rapid and specific changes in gene transcription, which are proposed to be mediated by members of two families, AUXIN RESPONSE FACTOR (ARF) and AUX/IAA (Guilfoyle, 1998; rev. in Hagen and Guilfoyle, 2002). Molecular markers were used to show that in young Arabidopsis leaf primordia, molecular auxin response patterns presage sites of procambial differentiation and the activity of the Arabidopsis gene ARF5/MONOPTEROS/MP, required for proper vascular differentiation, is essential for the regulation of rapidly auxin-inducible AUX/IAA genes, as well as auxin inducible vascular regulators. Regulatory properties of both MP/ARF5 and the closely related ARF7/NPH4 gene seem far more related than suggested by their single mutant phenotypes. The two gene products selectively interact with themselves and with each other, are expressed in overlapping domains, and regulate downstream processes in similar, but quantitatively distinguishable ways. Together these results provide evidence for the biological relevance of ARF-ARF interactions in Arabidopsis plants. Tissue specific auxin responses and potential targets of MP are determined. Consistent with the MP expression pattern, MP is shown to be required for the auxin signal transduction in pericycle cells, for the initiation of lateral roots, conversely, MP is not required for auxin mediated gravitropic responses in the outer tissue layers of the root. To increase the resolution in vascular tissue analysis we identified 34 markers specific to vascular cell and tissue types within a new collection of transactivated enhancer trap lines. The cloning of 23 lines, expression pattern and conditional phenotypes are reported, providing a compendium of markers for different tissues and stages of vascular development which can be used to target cell and tissue specific expression of hetereologous genes.
Shame on thy beard!: a study of insult, redress and the process of law in two "Owein" romances

Arthurian narrative has long enjoyed a pre-eminence among the several literatures of western Europe, and of the numerous tales about Arthur and his warriors, the stories of the knight with the lion have proven to be incredibly popular. This narrative traces the progression of its hero, Owein in the Welsh and Ywain in the English, from a very self-centred knighthood based on the pursuit of personal glory, through a series of adventures in the service of others. Critics of each version of the tale have observed that in relying less on his own prowess, and using his skills to benefit those he serves rather than to augment his own fame, the hero comes to a vital understanding of the responsibilities of a true knight and the real essence of chivalry. I believe that the process of fall and redemption, the education or re-education of the hero, is informed by notions of insult and redress which characterise societies that feud. In this dissertation, I examine the presence and extent of legal and feud elements and the process of feud itself in two Owein romances: the Welsh Owein and the Middle English Ywain and Gawain. A ribbon of insult and redress runs through each romance. The Welsh were a feuding people, and the text has direct legal references. The anonymous English author of Ywain and Gawain expresses sentiments of a feud culture, especially the sanctity of the spoken vow. Legal references are less direct but present, and there is an ever-present sense of a need to make amends for offences. The romance shows a concern for land law and royal centralising tendencies. The process of feud and the concern for honour, along with the sentiment of reciprocity and exchange which inform them, are so integral to the cultures which produced Owein and Ywain and Gawain that familiarity with this mentalité is essential to fully appreciate and understand the literature. Feud provides a rationale for adventures easily understood by a contemporary audience because that audience itself practiced the behaviours depicted in the literature, or at least understood the sentiment which encouraged them.
The role of Notch signaling during alphabeta and gammadelta T cell lineage commitment and differentiation

The requirement for thymus-derived factors in supporting thymocyte differentiation are increasingly being appreciated, however, their precise role and mechanism of action remain to be elucidated. Notch receptor-ligand interactions are indispensable for T lineage specification, yet the requirement for Notch signals at later stages in T cell development are still under investigation. In this work, the role of Notch-ligand interactions during alphabeta and gammadelta T cell lineage commitment is delineated. This is accomplished by employing an in vitro T cell differentiation system in which the availability of Notch ligand Delta-like 1 (Dll1) and the precise timing of T cell receptor (TCR) expression (pre-TCR or gammadeltaTCR) and thus, developmental transition, are controlled. Expression of the pre-TCR defines a critical developmental checkpoint termed beta-selection. This work uncovers an obligatory cooperation between Notch and pre-TCR-mediated signals for the functional outcomes of beta-selection including proliferation, rescue from apoptosis, and developmental progression. The necessity for Notch signals at this checkpoint reflects, in part, its role in promoting pre-TCR-independent pre-T cell survival through the maintenance of glucose metabolism. In this regard, the trophic effects of Notch signaling are mediated by the phosphatidylinositol-3-kinase/Akt pathway, such that the expression of active Akt substitutes for Notch during beta-selection. This role for Notch likely anticipates the bioenergetic demands associated with pre-TCR-triggered proliferation and differentiation. Notably, whereas Notch-ligand interaction is indispensable for alphabeta development, irrespective of the inductive TCR complex, gammadelta T cell differentiation can occur effectively in the absence of Notch signals from T lineage committed progenitors once gammadeltaTCR expression is attained. The work in this Thesis also provides insight into the role of Notch signals during alphabeta versus gammadelta T cell lineage decision, which has remained controversial. Employing progenitor frequency analysis encompassing clonal assays, it is now clear that Notch-Dll1 interactions do not mediate a binary fate decision. Moreover, this work positions the alphabeta/gammadelta lineage bifurcation to the DN3 stage and underscores the central role of TCR complex formation in T cell lineage commitment. Collectively, this Thesis elucidates the role of Notch signals at a critical checkpoint in T cell development where commitment to the alphabeta and gammadelta lineages occurs.
A proposed intelligent bandwidth management system based on Turksen's Fuzzy Function approach using reinforcement learning forecasting

In the telecom industry, there is a continuously increasing pressure to find more effective ways of managing available resources, such as bandwidth. The nature of the bandwidth allocation problem lends itself to the field of industrial engineering and operations research, because it is an optimization problem. However, upon further inspection of the complexity of this problem, it eventually becomes clear that finding an optimal solution will not be computationally feasible. However, by employing appropriate computational search techniques, a good solution may be approximated. This thesis approaches this problem in a systematic, two-stage process. The first is to use Reinforcement Learning (RL) techniques to learn the dynamic nature of the environment. The resulting forecasts shall then be used as an input for a newly proposed fuzzy system modeling approach, namely, Turksen's Fuzzy Functions [17]. A model comparison between ordinary regression and Fuzzy Functions is then made. This thesis purports that the Fuzzy Function approach represents a paradigmatic advancement from classical regression. This thesis may be of interest to industrial engineers involved in planning and decision support, computer scientists studying artificial intelligence, and engineers and managers in the telecom industry.
Motion segmentation incorporating active contours for spatial coherence

This thesis describes a computer vision algorithm that detects and segments independently moving objects in a video sequence, recovering their shape over time. While traditional motion segmentation approaches employ learned or low-dimensional parametric models to represent object shape, we propose a hybrid framework that combines robust motion segmentation with active-contour-based boundary recovery techniques, to overcome each individual approach's limitations. Our framework proposes feeding forward motion segmentation results to initialize, constrain and propagate the active contour, while feeding back active-contour-based object boundary estimates to the motion segmentation process to provide spatial coherence. We develop a functional system based on this framework, introducing a novel motion-based intensity constraint, and an active contour formulation that incorporates motion segmentation results. Our results demonstrate the successful segmentation of sequences that include multiple moving objects and sequences with a moving background.
Comparative analysis of tropoelastin structure and sequence in vertebrates

Elastin provides elasticity and resilience to tissues such as skin, lungs, ligaments, elastic cartilage and large blood vessels. It has been identified in most classes of vertebrates except for the cyclostomes. The soluble precursor to elastin, tropoelastin, has been sequenced in chicken and several species of mammals. It is one of the most glycine-rich hydrophobic proteins known and has a characteristic alternating domain structure. We have identified and sequenced two zebrafish tropoelastin homologues. Both share similar amino acid compositions, style of the primary sequence and synteny to LIMK1 with the other homologues. However most exons in these two genes cannot be aligned with mammalian and avian homologues except for the highly conserved C-terminal domain and several exons in the N-terminal region. Analysis of this non-homologous region shows signs of exon expansion through intronic recombination. This indicates that mammalian and zebrafish tropoelastin non-homologous regions result from separate expansion events, suggesting that the ancient tropoelastin protein could be considerably smaller in size.
On our yellow backs, under western eyes: Creating the nation and its citizens as White vis-à-vis the Asian woman in Hollywood cinema

The focus of my thesis will concern how Hollywood cinema produces the nation and its citizens as White, through the Asian woman in a predominantly White movie cast. I will concentrate on discourses that maintain Asian women as foreigners and center Whites as legitimate citizens in the imagination of Canada and the United States. I will presume popular culture is a tool of imperialism that reinscribes the dominion of Whiteness and analyze this imperial function through an anti-racist and feminist framework. I will examine popular contemporary Hollywood films such as Charlie's Angels (McG, 2000), Charlie's Angels 2: Full Throttle (McG, 2003), Snow Falling on Cedars (Hicks, 1999) and X2 (Singer, 2003) to probe how the Asian woman maintains the nation and its citizens as White.
