L’intégration identitaire, la perception de compatibilité, de complémentarité et de cohérence entre les différentes identités d’un individu, est associée à un plus grand ajustement psychologique. Selon le modèle cognitif développemental de l’intégration des identités sociales (MCDIIS), la création de liens cognitifs entre les identités et le regroupement de celles-ci dans des identités supraordinales seraient les principaux mécanismes derrière l’intégration. Le présent programme de recherche propose de définir et d’investiguer empiriquement les processus cognitifs derrière l’intégration identitaire. Suivant les modèles connexionnistes et bayésiens de la cognition, il est proposé que l’apprentissage d’associations et de catégories explique les processus d’intégration identitaire. En effet, selon les modèles connexionnistes, la perception de similarités entre les identités et l’exposition simultanée à celles-ci favorise la création de liens cognitifs. De plus, les modèles bayésiens de la catégorisation suggèrent que les représentations des identités supraordinales se complexifient avec le temps et l'expérience, passant d'une représentation prototypique à une représentation par exemplaires. Les représentations par exemplaires étant plus flexibles, celles-ci devraient être associées à plus d'intégration. Trois articles destinés à tester ces hypothèses sont présentés. Le premier article vise à déterminer si des liens cognitifs sont établis entre les identités intégrées. Le second article vise à déterminer la plausibilité des mécanismes cognitifs de façon corrélationnelle. Le troisième et dernier article étudie le rôle des représentations de l'identité de l'exogroupe et des identités supraordinales dans l'intégration. Dans l'ensemble, les résultats des études présentées dans les articles suggèrent que les mécanismes proposés par le MCDIIS sont plausibles. / Identity integration, the perception of compatibility, complementarity and coherence between an individual's different identities, is associated with greater psychological adjustment. According to the Cognitive Developmental Model of Social Identity Integration (CDMSII), the creation of cognitive links between identities and the grouping of identities into supraordinal identities are the main mechanisms behind integration. The present research programme proposes to define and empirically investigate the cognitive processes behind identity integration. Following connectionist and Bayesian models of cognition, it is proposed that association and category learning explain identity integration processes. Indeed, according to connectionist models, the perception of similarities between identities and the simultaneous exposure to them promotes the creation of cognitive links. Moreover, Bayesian models of categorization suggest that the representation of supraordinal identities become more complex with time and experience, going from a prototypîcal representation to a representation by exemplars. As representations by exemplars are more flexible, they should be associated with more integration. Three papers designed to test these hypotheses are presented. The first paper investigates whether cognitive links are established between integrated identities. The second paper investigates the plausibility of cognitive mechanisms in a correlational manner. The third and final paper examines the role of representations of exogroup identity and supraordinal identities in integration. Overall, the results of the studies presented in the papers suggest that the mechanisms proposed by the CDMSII are plausible.

The advent of Internet based digital services, and bandwidth-intensive business and personal applications has necessitated deployment of broadband network access technologies. Research analysts project that the U.S. market for broadband wireless networking will grow to nearly $2 billion by 2004 and Local Multipoint Distribution Services (LMDS) have enormous potential to emerge as the most reliable and cost-effective solution. However, in order to design and deploy LMDS systems, it is vital for system designers to be able to predict the behavior of mm-waves (28, 38 and 60GHz) during different weather conditions, especially rain. This research attempts to characterize the performance of pico-cell scenario broadband wireless channels by measuring path loss statistics during different weather conditions. Hardware and software components of a wideband direct-sequence spread spectrum (DSS) channel sounding system, used extensively throughout measurement campaigns, are discussed in detail in this dissertation. The measurement plan comprehensively describes the methodology, logistics, equipment setup, and calibration procedures for propagation measurement campaigns. Power Delay Profile (PDP) snapshots recorded during measurement campaigns are thoroughly analyzed using the 'Channel Imaging Analysis Suite' and Path Loss as well as Rain Attenuation statistics, calculated from recorded PDP data files, are classified and tabulated on the basis of measurement locations, propagation frequencies and antenna polarizations. Path Loss Exponent values are also calculated and Rain Attenuation statistics are compared with popular rain models. Results from Frequency Diversity measurement campaigns are also presented. / Master of Science

Teachers and students are invited to attend learning environments mediated by computer. Taking this need into account, this study contemplates the distance education context and aims at analyzing reculturing, restructuring and retiming processes (Fullan, 1996) in teacher-students discourse at Teachers Links Programme at PUCSP, intended for state school teachers of English. The main theoretical underpinning for the research is provided by studies of Fullan (1996), Hannay & Ross (1997) about reculturing, restructuring and retiming processes. The study also addresses the concept of social and teaching presence by Garrison & Anderson (2003). The research questions are the following: 1) How do teachers discourses collaborate for teachers-students live deeply possible reculturing, restructuring and retiming processes? 2) What evidence of reculturing, restructuring and retiming processes can be seen, during the process of learning in the teachers-students messages? The research methodology is based on interpretative approach with analyzing discussion forums and interviews with the participants. Results suggest some linguistic data that can characterize processes of reculturing, structuring and retiming processes in the teachers-students discourses / As transformações ocorridas na sociedade nas últimas décadas vêm sugerindo novas configurações nas práticas educacionais. Professores e alunos são convidados a participar de ambiente de aprendizagem mediado por computador. Considerando esse cenário, este trabalho se insere no contexto de Educação a distância e tem como finalidade analisar indícios de processo de reculturação, reestruturação e reorganização temporal (Fullan, 1996) no discurso de professores-alunos do Programa Teachers Links da PUC-SP, dirigido a professores de inglês de escolas públicas. O trabalho encontrou suporte teórico nos estudos de Fullan (1996), Hannay & Ross (1997) sobre o conceito de reculturação, reestruturação e reorganização temporal. Esta pesquisa também discute o conceito de presença social e de ensino de Garrison & Anderson (2003). As questões que nortearam a pesquisa foram as seguintes: 1) De que forma o discurso das professoras colabora para que os discentes vivenciem possíveis processos de reculturação, reestruturação e reorganização temporal? 2) Que possíveis indícios de reculturação, reestruturação e reorganização temporal podem ser observados, durante o processo de aprendizagem nas mensagens dos professores-alunos? A metodologia de pesquisa teve uma abordagem interpretativa com análise das interações em fóruns de discussão e entrevistas com os participantes. Os resultados sugerem algumas evidências lingüísticas que podem ser sinalizadores de processos de reculturação, reestruturação e reorganização temporal no discurso dos professores-alunos

Ziel der Arbeit ist die theoretische Analyse von Kohlenstoff-Clustern der Größe 100 - 500 Atome. Die experimentellen Beobachtungen sind bei dieser geringen Anzahl der Atome schwierig. Anderseits sind Kenntnisse über solche Cluster sehr wichtig, z.B. für die Keimbildung von Diamant auf Substraten, oder für die Kohlenstoff-Nanotechnologie (Fullerene, Nanotubes), oder für strukturelle Defekte in Kohlenstoff-Systemen. Es wurden gekrümmte Grenzflächen im Diamant simuliert. Zuerst mit einem empirischen Potential. Es wurde danach eine Methode entwickelt, bei der die schwach gestörten Gebiete einem empirischen Potential gehorchen, und die stark gestörten Gebiete, wo eine genaue Berechnung erforderlich ist, durch eine quantenmechanische Näherung beschrieben wurden. Somit kann man mit guter Genauigkeit große Systeme, bestehend aus einigen 10 (hoch)4 Atomen, simulieren, bei denen nur lokal quantenmechanische Methoden erforderlich sind. Mit diesem Hybrid-Code wurden weiterhin Diamantkeime auf Silizium gerechnet. Es wurden Aussagen bezüglich der Stabilität des Diamants auf dem Siliziumsubstrat, der kritischen Keimgröße, der Änderungen, die der Keim erfährt, gemacht. Ein anderes Gebiet ist die molekulardynamische Simulation bezüglich der Stabilität und des Transformationsverhaltens von Kohlenstoff-Nanoteilchen. Es wurden als »Rohstoffe» sowohl Diamant- und Graphitkristalle sphärischer, ellipsoidischer oder quadratischer Form benutzt, als auch amorpher Kohlenstoff. Es wurde demonstriert, daß sich Diamant unter höherer Temperatur und Bestrahlung in Kohlenstoffzwiebeln transformiert. Es wurde der innere Kern, bestehend aus zwei Schalen, der Kohlenstoffzwiebel simuliert. Es wurde, nach meinem Wissen, zum ersten Mal gezeigt, daß zwischen den Schalen der Kohlenstoffzwiebel Quer-Verbindungen (cross-links) existieren. Diese waren von den Experimentatoren vermutet worden. Sie bilden die Initiatoren der Diamantkeime der Kohlenstoffzwiebel bei ihrer ohne äußeren Druck möglichen Transformation in Diamant. Die Zentren der Kohlenstoffzwiebeln befinden sich bereits in der Entstehung der Zwiebel unter einem Selbstdruck. Bei den größeren Kohlenstoffzwiebeln beträgt der experimentell bestimmte Abstand zwischen den Schalen von außen nach innen von 3.34 Å bis 2.2 Å.

The experimental studies are at such small clusters heavy. Knowledges about thus clusters are very important, for example in the field of the nucleation of diamond on substrates, or for the carbon nano-technology (fullerene, nanotubes), or for local defects in carbon systems. There were simulated curved interfaces in diamond. Firstly with an empirical potential. Than I developed a method, in wich the defects and the structure around them are treated by a quantum mechanical algorithm and the rest with a near to ideal structure with an empirical potential. So, it is possible an accurate calculation of great systems of about 10 (high)4 atoms on wich only locally quantum mechanical methods are necessary. With this hybrid-code diamond nuclei on silicon substrate were simulated. The stability of the diamond nuclei on the silicon substrate, the critical radius of the nuclei and the changes of the nuclei during his transformation was investigated. Another field of investigations is the molecular dynamics simulation of free carbon clusters. The initial structures had spherical, ellipsoidical or square form and consists of diamond and graphite or a free form in the case of amorphous carbon. It was demonstrated that diamond transforms at higher temperatures and under irradiation in carbon onions. The genesis of the nucleus of a carbon onion with two shells was here for the first time simulated. The existence of the cross-links between the shells of a carbon onion was demonstrated. These existence was expected from the experimentators. The cross-links are the initiators of the transformation of carbon onions to diamond. The center of carbon onions is under self-pressure, because the distance between the outer shells is about 3.34 Å and between the inner shells about 2.2 Å.

In this thesis, we study the tradeoff of average delay with average service cost and average utility for both continuous time and discrete time single server queueing models without and with admission control. The continuous time and discrete time queueing models that we consider are motivated by cross-layer models for point-to-point links with random packet arrivals and fading at slow and fast time scales. Our studies are motivated by the need to optimally tradeoff the average delay of the packets (a network layer performance measure) with the average service cost of transmitting the packets, e.g. the average power required for transmission (a physical layer performance measure) under a lower bound constraint on the average throughput, in various point-to-point communication scenarios. The tradeoff problems are studied for a class of monotone and stationary scheduling policies and under the assumption that the service cost rate and utility rate are respectively convex and concave functions of the service rate and arrival rate. We also consider the problem of optimally trading off the average delay and average error rate of randomly arriving message symbols which are transmitted over a noisy point-to-point link, in which case the service cost function is non-convex. The solutions to the tradeoff problems that we address in the thesis are asymptotic in nature, and are similar in spirit to the Berry-Gallager asymptotic bounds. It is intuitive that to keep a queue stable under a lower bound constraint on the average utility a minimum number of customers have to be served per unit time. This in turn implies that queue stability requires a minimum average service cost expenditure. In the thesis we obtain an asymptotic characterization of the minimum average delay for monotone stationary policies subject to an upper bound constraint on the average service cost and a lower bound constraint on the average utility, in the asymptotic regime where the average service cost constraint is made arbitrarily close to the above minimum average service cost. In the thesis, we obtain asymptotic lower bounds on the minimum average delay for the cases for which lower bounds were previously not known. The asymptotic characterization of the minimum average delay for monotone stationary policies, for both continuous time and discrete time models, is obtained via geometric bounds on the stationary probability of the queue length, in the above asymptotic regime. The restriction to monotone stationary policies enables us to obtain an intuitive explanation for the behaviour of the asymptotic lower bounds using the above geometric bounds on the stationary probability distribution of the queue length. The geometric bounds on the stationary probability of the queue length also lead to a partial asymptotic characterization of the structure of any optimal monotone stationary policy, in the above asymptotic regime, which was not available in previous work. Furthermore, the geometric bounds on the stationary probability can be extended to analyse the tradeoff problem in other scenarios, such as for other continuous time queueing models, multiple user communication models, queueing models with service time control, and queueing models with general holding costs. Usually, queueing models with integer valued queue evolution, are approximated by queueing models with real valued queue evolution and strictly convex service cost functions for analytical tractability. Using the asymptotic bounds, we show that for some cases the average delay does not grow to infinity in the asymptotic regime, although the approximate model suggests that the average delay does grow to infinity. In other cases where the average delay does grow to infinity in the asymptotic regime, our results illustrate that the tradeoff behaviour of the approximate model is different from that of the original integer valued queueing model unless the service cost function is modelled as the piecewise linear lower convex envelope of the service cost function for the original model.

Thesis (MDF (Development Finance))--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: It is a fact that development aid represents the single most important source of external finance for most developing countries. This study sought to answer an important question relating to whether aid has a positive impact on economic growth or not. There is much literature on the subject and the views are quite diverse. Using the World Development Indicators (WDI) data, a cross-section regression analysis was performed over a period of 16 years and existing literature on the subject was re-examined. Of importance, this study tries to understand what the determinants or triggers of economic growth are, especially in developing economies. The results show that, although no significant relationship could be found between economic growth and development aid, there is strong evidence that there is a significant positive relationship between economic growth and the important triggers of economic growth used in the study, namely exports and investments. These are important components for the growth of any economy. The implicit conclusion is that since these two components are being impacted positively by aid, it follows then that the link between economic growth and aid can be considered to be a positive one. These findings go against the critics of development aid who maintain that aid that is being pumped into developing economies, especially the African continent, is actually just going into a big black hole and could be used more effectively somewhere else. This study proves that this is not the case and donor countries need to intensify their efforts of providing aid to poor countries because they need it and it is actually making a difference. AFRIKAANSE OPSOMMING: Dit is ‘n algemeen aanvaarde feit dat ontwikkelingsteun die enkel belangrikste bron van eksterne finansiering is vir die meeste ontwikkelende lande. Hierdie studie poog om antwoorde te vind vir die belangrike vraag of steun ‘n positiewe impak op ekonomiese groei het of nie. Daar is volop literatuur oor die onderwerp beskikbaar en die opvattings is uiters uiteenlopend. Deur die World Development Indicators data te gebruik, is ‘n deursnit regressie analise gedoen oor ‘n periode van 16 jaar en bestaande literatuur oor die onderwerp is weer ondersoek. Die belangrikste oogmerk van die studie is om te probeer verstaan wat die bepalers of snellers van ekonomiese groei is, veral in ontwikkelende ekonomië. Die uitslae toon dat, alhoewel daar geen beduidende verhouding gevind kon word tussen ekonomiese groei en ontwikkelingsteun nie, daar wel sterk bewyse is vir ‘n beduidende positiewe verhouding tussen ekonomiese groei en die belangrike snellers van ekonomiese groei soos gebruik in die studie, naamlik uitvoere en beleggings. Hierdie is belangrike komponente vir die groei van enige ekonomie. Die implisiete afleiding is dus dat, aangesien hierdie twee komponente positief beïnvloed word deur ontwikkelingsteun, dit volg dat die skakel tussen ekonomiese groei en steun ook as ‘n positiewe een beskou kan word. Hierdie bevindings is lynreg in teenstelling met die kritici van ontwikkelingsteun wat handhaaf dat steun wat aan ontwikkelende lande, veral in Afrika, gegee word, eintlik net in ‘n groot swart gat verdwyn en meer effektief elders aangewend kan word. Hierdie studie bewys dat dit nie die geval is nie en dat skenker lande eerder hulle pogings om steun aan arm lande te bied moet verskerp omdat hulle dit nodig het en omdat dit regtig ‘n verskil maak.

La compréhension de la structure d’un logiciel est une première étape importante dans la résolution de tâches d’analyse et de maintenance sur celui-ci. En plus des liens définis par la hiérarchie, il existe un autre type de liens entre les éléments du logiciel que nous appelons liens d’adjacence. Une compréhension complète d’un logiciel doit donc tenir compte de tous ces types de liens. Les outils de visualisation sont en général efficaces pour aider un développeur dans sa compréhension d’un logiciel en lui présentant l’information sous forme claire et concise. Cependant, la visualisation simultanée des liens hiérarchiques et d’adjacence peut donner lieu à beaucoup d’encombrement visuel, rendant ainsi ces visualisations peu efficaces pour fournir de l’information utile sur ces liens. Nous proposons dans ce mémoire un outil de visualisation 3D qui permet de représenter à la fois la structure hiérarchique d’un logiciel et les liens d’adjacence existant entre ses éléments. Notre outil utilise trois types de placements différents pour représenter la hiérarchie. Chacun peut supporter l’affichage des liens d’adjacence de manière efficace. Pour représenter les liens d’adjacence, nous proposons une version 3D de la méthode des Hierarchical Edge Bundles. Nous utilisons également un algorithme métaheuristique pour améliorer le placement afin de réduire davantage l’encombrement visuel dans les liens d’adjacence. D’autre part, notre outil offre un ensemble de possibilités d’interaction permettant à un usager de naviguer à travers l’information offerte par notre visualisation. Nos contributions ont été évaluées avec succès sur des systèmes logiciels de grande taille. / Understanding the structure of software is an important first step in solving tasks of analysis and maintenance on it. However, in addition to the links defined by the hierarchy, there exists another type of links between elements of software that are called adjacency links. A complete understanding of software must take account of all these types of links. Visualization tools are generally effective in helping a developer in his understanding of software by presenting the information in a clear and concise manner. However, viewing these two types of links generate in general a lot of visual clutter, making these visualizations inefficient to provide useful information on these links. We propose in this M.Sc. thesis a 3D visualization tool that can represent both the hierarchical structure of an application and the adjacency relationships between its elements. Our tool uses three different types of layout to represent the hierarchy. Each layout can support efficiently the display of adjacency links. To represent adjacency links, we propose a 3D version of the Hierarchical Edge Bundles algorithm. We also use a metaheuristic algorithm to improve our layouts to further reduce visual clutter in the adjacency links. Moreover, our tool provides a set of interaction possibilities that allows a user to navigate through the information provided by our visualization. Our contributions have been evaluated successfully on large software systems.

Cette recherche s’intéresse aux impacts sociopolitiques des gazoducs et des oléoducsmis en oeuvre depuis 1991 au Caucase du Sud. S’appuyant sur un cadre théoriquemêlant principalement sociologie de l’Acteur-Réseau, sociologie éliasienne etapproches managériales, elle postule que la construction d’un système complexe detransport de pétrole et de gaz azerbaïdjanais est révélatrice de l’évolution de laconfiguration sud-caucasienne. Cette thèse étudie tout d’abord les interactions qui senouent autour de la mise en oeuvre des voies d’exportation des hydrocarburesazerbaïdjanais. Elle met en lumière l’émergence de nouvelles formes de régulation, dontla plupart profite à la compagnie pétrolière BP. Elle démontre ensuite comment lesréseaux sociotechniques construits autour de ces nouvelles voies participent d’uneévolution de la configuration sud-caucasienne. Ces réseaux débordent du cadrepurement économique pour aboutir au développement de la régionalisation entrel’Azerbaïdjan, la Géorgie et la Turquie. Cette recherche souligne enfin les gains queretire l’Etat-entreprise azerbaïdjanais de cette régionalisation fondée sur leshydrocarbures. Bakou se sert de ces derniers pour étendre son influence économique etpolitique au sein de la configuration sud-caucasienne. La sociologie de l’Acteur-Réseaunous permet donc de souligner le rôle non seulement économique mais égalementpolitique des hydrocarbures dans la montée en puissance de l’Azerbaïdjan qui, d’Etat enfaillite, est devenu puissance régionale. / This dissertation looks at the socio-political impacts of the pipelines that have beenimplemented in the South Caucasus since 1991. It is based on a theoreticalframework mixing Actor-Network Theory, Norbert Elias’s sociology andmanagement approaches. It assumes that the construction of an Azerbaijanihydrocarbons transportation complex system sheds light into the evolution of theSouth Caucasian configuration. First, this research studies interactions that emergeLUSSAC Samuel | Science Politique | Doctorat | 201114around the implementation of export routes for Azerbaijani oil and gas resources.It highlights the development of new forms of governance, which mostly benefit tothe oil company BP. Second, this dissertation demonstrates that the sociotechnicalnetworks built around these new export routes contribute to the evolution of theSouth Caucasian configuration. These networks overflow the economic sphere tofoster regionalization between Azerbaijan, Georgia and Turkey. Third, thisresearch underlines the benefits the Azerbaijani ‘state-company’ retrieves fromthis hydrocarbons-based regionalization. Baku takes advantage of oil and gasresources to increase its economic and political influence within the SouthCaucasian configuration. Therefore, the Actor-Network Theory helps to shed lightinto the economic and political role of hydrocarbons in the rise of Azerbaijan.From a failed state, this country has now established itself as a regional power.
