Back to Basics: Exploring gestural habits as cues for anticipating self-injurious episodes in a child with Autism and Deafness

This research project is a longitudinal qualitative case study. It contributes to an understanding of self-injurious behaviour (SIB) by inviting the reader through the narrative of the lived experience of a fifteen year old child-informant and the network of individuals in his life. The value and importance of a case-study is that it focuses on the authenticity of the experience of living with disability. Through the use of detailed field observations, interviews and photo documents, the study thoroughly explores three main areas: quality of movements, potential cues as pre-cursors to episodes of self-injury, and purposeful communication. The research begins with a review of literature on Autism, Deafness and Self-injury, formulates the research design and orientation of Physical Education, Phenomenology and Semiotics, and then systematically explores four distinct phases in the analytical process. The aim was to explore self-injurious episodes in the child informant in hopes to translate the meaning of the behaviour and potentially utilize this to provide more opportunities for adapted physical activity. The findings reveal distinct patterns of movement cues utilized for different purposes. The implications of the findings are self-injurious episodes in the child informant are preceded by distinct patterns of movement that are potentially communicative. Suggested future direction of the research is expanding the scope to other disabilities for which verbal communication is challenging, and standardizing the translating tools to assist in understanding the communication of movement.

Back to School, Back to Normal? Exploring the Lived Experiences of Childhood Cancer Survivors and their Families Throughout the School Re-Entry Process

This study investigated parent and child perspectives of childhood cancer survivors' return to school. Four specific areas were examined including cognitive and academic concerns, social issues, perceived support, and the impact on siblings. Participants consisted of parents and childhood cancer survivors who were recruited through a regional parent support group. Data was collected during a focus group and interviews. Using a descriptive content analysis, results indicated that participants generally received the necessary resources, however issues such as consistency and having to advocate in order to attain these resources served as barriers for the families.

Bringing Zombies Back to Life: An Autoethnographical Exploration of Alienation and Political Dis/Engagement in Emerging Adulthood Within Late-Stage Capitalism

In this thesis, by employing an autoethnographic methodology, I am exploring why certain understandings, or assemblages, of political engagement come to have greater meaning in my life and why other assemblages may be more hidden and thus fail to contribute substantially to the meaning of political in my life. Using immanent, Marxist and post-Marxist theories, as well as a zombie narrative, the study will contextualize the movement of assemblages in my life within late-stage capitalism which is juxtaposed with the zombie apocalypse. The placement and displacement of certain understandings of the political within my life will be theorized within the crisis of constituent power that is revealed in an immanent framework. Furthermore, the crisis of the constituent in late-stage capitalism creates new forms of radical alienation which will also be examined. By exploring my own struggles in becoming political I will theorize why political disengagement in emerging adulthood appears to be increasing, as well as possibilities for new forms of political engagement in a late-stage capitalist context.

Assessing waiting times in the clinical trajectory of patients with lung cancer

Le cancer du poumon a une incidence et une létalité parmi les plus hautes de tous les cancers diagnostiqués au Canada. En considérant la gravité du pronostic et des symptômes de la maladie, l’accès au traitement dans les plus brefs de délais est essentiel. Malgré l’engagement du gouvernement fédéral et les gouvernements provinciaux de réduire les délais de temps d’attente, des balises pour les temps d’attente pour le traitement d’un cancer ne sont toujours pas établis. En outre, le compte-rendu des indicateurs des temps d’attente n’est pas uniforme à travers les provinces. Une des solutions proposées pour la réduction des temps d’attente pour le traitement du cancer est les équipes interdisciplinaires. J’ai complété un audit du programme interdisciplinaire traitant le cancer du poumon à l’Hôpital général juif (l’HGJ) de 2004 à 2007. Les objectifs primaires de l’étude étaient : (1) de faire un audit de la performance de l’équipe interdisciplinaire à l’HGJ en ce qui concerne les temps d’attente pour les intervalles critiques et les sous-groupes de patients ; (2) de comparer les temps d’attente dans la trajectoire clinique des patients traités à l’HGJ avec les balises qui existent ; (3) de déterminer les facteurs associés aux délais plus longs dans cette population. Un objectif secondaire de l’étude était de suggérer des mesures visant à réduire les temps d’attente. Le service clinique à l’HGJ a été évalué selon les balises proposées par le British Thoracic Society, Cancer Care Ontario, et la balise pan-canadienne pour la radiothérapie. Les patients de l’HGJ ont subi un délai médian de 9 jours pour l’intervalle «Ready to treat to first treatment», et un délai médian de 30 jours pour l’intervalle entre le premier contact avec l’hôpital et le premier traitement. Les patients âgés de plus de 65 ans, les patients avec une capacité physique diminuée, et les patients avec un stade de tumeur limité étaient plus à risque d’échouer les balises pour les temps d’attente.

Src family kinases are required for limb trajectory selection by spinal motor axons

Signal relay by guidance receptors at the axonal growth cone is a process essential for the assembly of a functional nervous system. We investigated the in vivo function of Src family kinases (SFKs) as growth cone guidance signaling intermediates in the context of spinal lateral motor column (LMC) motor axon projection toward the ventral or dorsal limb mesenchyme. Using in situ mRNA detection we determined that Src and Fyn are expressed in LMC motor neurons of chick and mouse embryos at the time of limb trajectory selection. Inhibition of SFK activity by C-terminal Src kinase (Csk) overexpression in chickLMCaxons using in ovo electroporation resulted inLMC axons selecting the inappropriate dorsoventral trajectory within the limb mesenchyme, with medial LMC axon projecting into the dorsal and ventral limb nerve with apparently random incidence. We also detected LMC axon trajectory choice errors in Src mutant mice demonstrating a nonredundant role for Src in motor axon guidance in agreement with gain and loss of Src function in chickLMCneurons which led to the redirection ofLMCaxons. Finally, Csk-mediated SFK inhibition attenuated the retargeting ofLMCaxons caused by EphA or EphB over-expression, implying the participation of SFKs in Eph-mediated LMC motor axon guidance. In summary, our findings demonstrate that SFKs are essential for motor axon guidance and suggest that they play an important role in relaying ephrin:Eph signals that mediate the selection of motor axon trajectory in the limb.

‘Bringing the Middle Classes Back In’ An Egalitarian Case for (Truly) Universal Public Services

Some egalitarians argue against public services that are free for all, on the grounds that free access appears to primarily benefit the middle classes. I advocate, instead, the inclusion of the middle classes in public services, arguing that only truly universal intake of public services prevents the inegalitarian effects of economic segregation. Such universal participation in public services is achieved, partly, through subsidies for, and regulation of, privately produced services.

Modéliser le processus d’appropriation du feed-back en évaluation du potentiel pour en optimiser les retombées positives auprès des candidats

L’appropriation du feed-back a fait l’objet de plusieurs modèles théoriques en contexte d’évaluation de la performance, notamment par Ilgen, Fisher et Taylor (1979) qui suggèrent un modèle explicitant comment un feed-back en vient à susciter des changements comportementaux. Ce modèle a été repris dans divers domaines de recherche, sans pour autant être adapté en fonction du contexte spécifique dans lequel le feed-back était transmis. Cette thèse propose un modèle d’appropriation du feed-back inspiré des travaux d’Ilgen et al. (1979), mais reflétant les spécificités de l’évaluation du potentiel. Le modèle comporte trois étapes qui sont l’appropriation cognitive (composée de l’acceptation et de la conscientisation), l’intention d’agir dans le sens du feed-back et l’appropriation comportementale. La présente thèse se décompose en trois articles poursuivant les objectifs suivants : (1) Proposer un modèle théorique de l’appropriation du feed-back adapté au contexte de l’évaluation du potentiel. (2) Valider une mesure de l’appropriation cognitive combinant l’acceptation et la conscientisation. (3) Tester empiriquement le modèle d’appropriation du feed-back en contexte d’évaluation du potentiel. Le premier article vise d’abord à circonscrire les fondements de l’évaluation du potentiel et à définir l’appropriation du feed-back. Sur la base de ces informations, le modèle d’Ilgen et al. (1979) est ensuite revu et modifié. Les liens entre les différentes étapes du modèle sont subséquemment étayés par des théories et des études empiriques. L’article se conclue par une réflexion sur les retombées théoriques et pratiques du modèle revisité. L’objectif du second article consiste à développer et valider une mesure de l’appropriation cognitive incluant deux dimensions, à savoir l’acceptation et la conscientisation. Pour ce faire, deux études ont été menées auprès de candidats ayant reçu un feed-back suite à une évaluation du potentiel. Des analyses factorielles exploratoires (N = 111), puis des analyses factorielles confirmatoires (N = 178) ont été réalisées en ce sens. Chaque dimension de l’appropriation cognitive a également été mise en relation avec des variables critères afin de recueillir des éléments de preuve appuyant la validité de l’instrument. La majorité des indices obtenus confirment la présence des deux dimensions pressenties et des constats sont tirés sur la base de ces résultats. Le troisième article vise à vérifier empiriquement les liens anticipés entre les composantes du modèle d’appropriation du feed-back détaillé dans le premier article. Les deux premières étapes du modèle, soit l’appropriation cognitive et l’intention d’agir, ont été mesurées via un questionnaire complété immédiatement après le feed-back par 178 candidats. Ces derniers ont été sollicités trois mois plus tard afin de compléter un second questionnaire portant sur la dernière étape, l’appropriation comportementale, et 97 d’entre eux y ont répondu. Les résultats d’analyses par équations structurelles supportent le modèle et une discussion sur la portée de tels résultats s’en suit.

Back muscles activity and scoliosis in ataxic and dystrophic patients

To investigate the role of muscles in the development of adolescent idiopathic scoliosis (AIS), our group was initially interested in Duchenne muscular dystrophy (DMD) diseases where a muscular degeneration often leads to scoliosis. Few years ago the studies with those patients provided interesting results but were obtained only from few patients. To increase that number, the present project was initiated but recruitment of new DMD patients from Marie-Enfant hospital was found impossible. As an alternative, patients with Friedreich’s ataxia (FA) were recruited since they also suffer from a muscular deficiency which often induces a scoliosis. So, 4 FA patients and 4 healthy controls have been chosen to closely match the age, weight and body mass indexes (BMI) of the patients were enrolled in our experiments. As in the previous study, electromyography (EMG) activity of paraspinal muscles were recorded on each side of the spine during three types of contraction at 2 different maximum voluntary contractions (MVC). Moreover, the volume and skinfold thickness of these muscles were determined from ultrasound images (US) in order to facilitate the interpretation of EMG signals recorded on the skin surface. For the 3 FA right scoliotic patients, EMG activity was most of the time larger on the concave side of the deviation. The opposite was found for the 4th one (P4, left scoliosis, 32°) for whom EMG activity was larger on the convex side; it should however be noted that all his signals were of small amplitude. This was associated to a muscle weakness and a large skinfold thickness (12 mm) vs 7 mm for the 3 others. As for the paraspinal muscle volume, it was present on the convex side of P1, P3 and P4 and on the concave side for P2. As for skinfold thickness over this muscle, it was larger on the concave side for P1 and P2 and the opposite for P3 and P4. At the apex of each curve, the volume and skinfold thickness differences were the largest. Although the study covers only a small number of FA patients, the presence of larger EMG signals on the concave side of a spinal deformation is similar to pre-scoliotic DMD patients for whom the deformation is in its initial stage. It thus seems that our FA patients with more EMG activity on their concave side could see progression of their spinal deformation in the coming months in spite of their already important Cobb angle.

Spectrum simulation of rough and nanostructured targets from their 2D and 3D image by Monte Carlo methods

Corteo is a program that implements Monte Carlo (MC) method to simulate ion beam analysis (IBA) spectra of several techniques by following the ions trajectory until a sufficiently large fraction of them reach the detector to generate a spectrum. Hence, it fully accounts for effects such as multiple scattering (MS). Here, a version of Corteo is presented where the target can be a 2D or 3D image. This image can be derived from micrographs where the different compounds are identified, therefore bringing extra information into the solution of an IBA spectrum, and potentially significantly constraining the solution. The image intrinsically includes many details such as the actual surface or interfacial roughness, or actual nanostructures shape and distribution. This can for example lead to the unambiguous identification of structures stoichiometry in a layer, or at least to better constraints on their composition. Because MC computes in details the trajectory of the ions, it simulates accurately many of its aspects such as ions coming back into the target after leaving it (re-entry), as well as going through a variety of nanostructures shapes and orientations. We show how, for example, as the ions angle of incidence becomes shallower than the inclination distribution of a rough surface, this process tends to make the effective roughness smaller in a comparable 1D simulation (i.e. narrower thickness distribution in a comparable slab simulation). Also, in ordered nanostructures, target re-entry can lead to replications of a peak in a spectrum. In addition, bitmap description of the target can be used to simulate depth profiles such as those resulting from ion implantation, diffusion, and intermixing. Other improvements to Corteo include the possibility to interpolate the cross-section in angle-energy tables, and the generation of energy-depth maps.
