abstract: ABSTRACT This study explored the functions of dialogue in emerging adults' moral turning points. Through purposive sampling, the researcher interviewed 10 emerging adults between 25 and 30 years old about experiences of turning point conversations during the years of 18 and 25. This study employed constant comparative and grounded theory methodologies to analyze messages reported in memorable conversations during this period. Results indicated that dialogue functioned to educate, disturb, and maintain emerging adults' moral perception during this period of moral reorientation. Subcategories under each included dialogue that functioned to explain, invite, warn, direct or instruct, challenge, persuade, agitate, expose, inquire, legitimize, co-reflect, redefine, and affirm or reinforce. This report cites passages from interview data to highlight how dialogic themes informed or shaped changes in moral perception. In each participant's self-reported turning point conversations there was an admixture of dialogic functions at work. Notably, participants' experience of moral turning (degree and trajectory) varied despite there being similarity in intended functions of dialogue. / Dissertation/Thesis / IRB Approval Form / M.A. Communication Studies 2010

Ce manuscrit est dédié à la détection et la caractérisation de points d'intérêt dans les maillages. Nous montrons tout d'abord les limitations de la mesure de courbure sur des contours francs, mesure habituellement utilisée dans le domaine de l'analyse de maillages. Nous présentons ensuite une généralisation de l'opérateur SUSAN pour les maillages, nommé SUSAN-3D. La mesure de saillance proposée quantifie les variations locales de la surface et classe directement les points analysés en cinq catégories : saillant, crête, plat, vallée et creux. Les maillages considérés sont à variété uniforme avec ou sans bords et peuvent être réguliers ou irréguliers, denses ou non et bruités ou non. Nous étudions ensuite les performances de SUSAN-3D en les comparant à celles de deux opérateurs de courbure : l'opérateur de Meyer et l'opérateur de Stokely. Deux méthodes de comparaison des mesures de saillance et courbure sont proposées et utilisées sur deux types d’objets : des sphères et des cubes. Les sphères permettent l'étude de la précision sur des surfaces différentiables et les cubes sur deux types de contours non-différentiables : les arêtes et les coins. Nous montrons au travers de ces études les avantages de notre méthode qui sont une forte répétabilité de la mesure, une faible sensibilité au bruit et la capacité d'analyser les surfaces peu denses. Enfin, nous présentons une extension multi-échelle et une automatisation de la détermination des échelles d'analyse qui font de SUSAN-3D un opérateur générique et autonome d’analyse et de caractérisation pour les maillages / This manuscript is dedicated to the detection and caracterization of interest points for 3D meshes. First of all, we show the limitations of the curvature measure on sharp edges, the measure usually used for the analysis of meshes. Then, we present a generalization of the SUSAN operator for meshes, named SUSAN-3D. The saliency measure proposed quantify the local variation of the surface and classify directly the analysed vertices in five classes: salient, crest, flat, valley and cavity. The meshes under consideration are manifolds and can be closed or non-closed, regulars or irregulars, dense or not and noised or not. The accuracy of the SUSAN-3D operator is compared to two curvature operators: the Meyer's operator and the Stokely's operator. Two comparison methods of saliency and curvature measures are described and used on two types of objects: spheres and cubes. The spheres allow the study of the accuracy for differentiable surfaces and the cubes for two types of sharp edges: crests and corners. Through these studies, we show the benefits of our method that are a strong repeatability of the measure, high robustness to noise and capacity to analyse non dense meshes. Finally, we present a multi-scale scheme and automation of the determination of the analysis scales that allow SUSAN-3D to be a general and autonomous operator for the analysis and caracterization of meshes

M.Tech. (Chiropractic) / Purpose: This study was undertaken in order to demonstrate the effects of static magnetic field therapy on acupuncture points in the treatment of those suffering from mechanical neck pain. Isolated spinal manipulative therapy of the cervical spine was compared to spinal manipulative therapy of the cervical spine in conjunction with magnetic field therapy on acupuncture points using both objective and subjective measurements. Before the execution of this study, it was hypothesised that both treatment protocols would be effective in the treatment of mechanical neck pain, although the combined therapy would be more effective. Method: Patients were recruited by way of advertisements placed in and around the University of Johannesburg, Doornfontein campus and their health clinic. Thirty patients with mechanical neck pain were recruited and randomly divided into two groups. Group one received manipulation to the affected joints of the cervical spine and group two received manipulation to the cervical spine combined with magnetic field therapy on acupuncture points. Procedure: Each patient in each group attended six treatment sessions; three in the first week and three in the second week. The Vernon Mior Neck Pain and Disability Index and the Numerical Pain Rating Scale (subjective measurements) were completed by each patient and the Cervical Range of Motion instrument (objective measurements) was used to collect readings from each patient in both the control and experimental groups, subjective and objective measurements were taken before treatment one, three and six. Specific treatment protocols were then adhered to. Results: The results indicated that both treatment protocols were effective in reducing mechanical neck pain although not one group was more effective than the other. Both groups improved subjectively and objectively as they had cervical spinal manipulation directed at joint dysfunction. Conclusion: The experimental group who received spinal manipulative therapy to correct joint dysfunction in conjunction with magnetic field therapy on acupuncture points was not more effective than the control group who received spinal manipulation only, in the treatment of mechanical neck pain.

L'interaction tactile multi-points co-localisée procure un fort sentiment de contrôle direct mais introduit des problèmes d'occultation, de précision et de fatigue. Ces problèmes sont exacerbés sur les écrans de grandes dimensions, qui supportent la manipulation de grandes quantités de données, souvent en collaboration avec d'autres utilisateurs. Pour résoudre ces problèmes, cette thèse s'intéresse à l'introduction d'indirections dans l'interaction multi-points sur grands écrans. Nos travaux portent sur l'étude des facteurs qui influencent la précision dans les tâches de sélection sans prévisualisation du contact. Les résultats de deux expériences contrôlées ont ainsi permis d'estimer la précision attendue selon les caractéristiques des périphériques d'entrée et de sortie et des conditions d'utilisation. Sur la base de ces connaissances, nos travaux portent également sur le développement de nouvelles techniques d'interaction pour écrans de grandes dimensions. Nous avons d'abord proposé une technique permettant d'interagir indirectement avec une tablette tactile, en introduisant la gestion de plusieurs curseurs contrôlés relativement. Nous avons ensuite conçu une interaction reposant sur la création de plusieurs périphériques virtuels qui supportent une interaction à la fois directe et indirecte tout en permettant de réorganiser les éléments d'une interface. Parallèlement à cela, nous avons transformé un écran mural de 6*2,4m en une surface tactile multi-points afin de pouvoir tester les techniques et scénarios discutés dans ces travaux. / Co-localized multi-touch interaction affords a high feeling of directness but introduces problems of occlusion, precision and fatigue. These problems are even more acute with large displays, supporting the interaction with large data sets, often in collaboration with other users. To solve these problems this thesis focuses on the introduction of indirections in multi-touch interaction on large displays. We first study factors impacting accuracy in selection tasks without contact preview. Results of two controlled experiments allowed to estimate the expected accuracy depending on input and output device characteristics and input conditions. Based on this knowledge, we developed new interaction techniques for large displays. We first introduced a technique to interact indirectly using a tactile tablet by introducing the control of several cursors using a relative mapping. Then we proposed an interaction technique based on the creation of multiple soft-devices that supports both direct and indirect interaction and allows to re-arrange the interface of legacy applications. In order to design, test and evaluate these techniques, we turned a back projected wall display (6*2,4m) into an interactive multi-touch surface.

This paper will be concerned with the convergence of complex power series.

We give algorithms to compute Coleman integrals on superelliptic curves over unramified extensions of the p-adics, and apply these via Chabauty methods to determine the set of rational points on such curves. We also determine the solution to an explicit instance of the Shafarevich conjecture by finding all elliptic curves with good reduction outside of the first 6 primes, subject to a heuristic. We use a combination of non-abelian Chabauty and the Mordell--Weil sieve to determine the rational points on several quotient modular curves, and therefore classify pairs of elliptic curves over the rationals with 67-, 73-, and 107-isogenies. We give methods to explicitly compute Coleman integrals on modular curves using a canonical lift of Frobenius and canonical local coordinates in each residue disk, and discuss the problem of computing the Weil pairing in finite rings.
