Les humains virtuels en interaction homme machine sont aujourd’hui établis comme un objet de recherche à part entière. Leurs comportements pensés pour différentes applications sont basés sur les routines d’interaction entre humains. Bien que les humains virtuels aient souvent un corps représenté graphiquement, les recherches actuelles souffrent de deux limitations majeures qui dégradent la crédibilité de l’expérience des utilisateurs : les comportements corporels modélisés manquent d’interactivité sociale et ne prennent pas en compte les différences interindividuelles. Les développements récents en Sciences Humaines promeuvent une approche plus intégrative avec en son cœur le rôle constitutif de l’interaction sociale. La position centrale et interdisciplinaire des humains virtuels dans ce nouvel agenda de recherche est particulièrement importante : ils sont à la fois une manière de mieux étudier les différents phénomènes d’interactions sociales (comme outil expérimental) et une solution potentielle à des défis sociétaux (comme applications). L’objectif principal de cette thèse est de combiner les apports et valoriser les synergies établies entre les sciences de l’informatique et les sciences humaines, afin d’appréhender le rôle modérateur des différences interindividuelles dans le contrôle et la régulation des interactions corporelles. L’objectif à plus long terme de cette contribution vise à développer des humains virtuels interactifs à l’interface de ces domaines, avec l’idée que les besoins des deux champs de recherches contraindraient de manière positive les propositions futures. Pour limiter le cadre de cette thèse, nous nous sommes concentrés sur les mouvements du corps (les aspects statiques du corps ou les autres modalités ne sont pas considérées), sur les mécanismes de couplages bas niveaux et le rôle modérateur des différences interindividuelles avec comme objectif de proposer des prototypes d’humains virtuels comme preuve de concept (plutôt que des logiciels fonctionnels complets) incluant des modèles d’interaction corporelle dyadique. Notre méthodologie peut être résumée en quatre étapes principales. Premièrement, les modèles et hypothèses liant les processus d’interaction sociale aux différences interindividuelles résultent d’une double revue de littérature en sciences de l’informatique et sciences humaines. Ces différences interindividuelles identifiées comme pertinentes apparaissant faiblement associées théoriquement, notre seconde étape consista à étudier leurs associations lors d’une étude à grande échelle. Troisièmement, les interactions corporelles ont été analysées dans deux études de cas qui présentent des intérêts applicatifs et expérimentaux. Dans les deux cas, des corpus multimodaux d’interactions corporelles dyadiques ont été collectés et associés à des mesures de différences interindividuelles. La phase finale fut de développer des prototypes d’humains virtuels inspirés par les analyses précédentes et basés sur les données collectées. Le modèle général portant sur la prise en compte des différences interindividuelles se révèle en accord avec les données collectées (questionnaires d’auto-évaluation) : les relations entre dispositions d’orientations pro-sociales, d’empathie et de régulation émotionnelle furent confirmées. Les deux études de cas validèrent partiellement les hypothèses initiales : certaines différences interindividuelles modulèrent les processus d’interaction corporelle. Ces études contribuent à la définition de modèles d’humains virtuels interactifs parcimonieux. La principale contribution critique de ces deux études de cas au rôle modérateur des différences interindividuelles dans le modèle proposé est la nécessité de prendre en considération le contexte de la tâche avant de définir les hypothèses. L’intégration de ces différences interindividuelles identifiées dans les études de cas aux modèles informatiques interactifs est incluse dans les directions de recherches futuresIn human computer interaction, virtual humans are now established as a specific object of research. They build on human to human interaction routines to serve various application goals. Although Virtual Humans (VH) have bodies, current researches suffer from two major limitations which impair the experienced credibility: modeled bodily behaviors lack of social interactivity and do not account for individual differences. Recent developments in human sciences call for a more integrative approach with at its heart the constitutive role of social interaction. Of particular importance is the central and interdisciplinary position of virtual humans in this new research agenda: they are both a way to better investigate the various socially interactive phenomena (VH as experimental tools) and potential solutions for societal challenges (VH as applications). The main goal of this PhD thesis is to contribute to both computer and human sciences by studying together bodily interaction and individual differences. Central to this study is the long term objective to develop interactive virtual humans at the interface of these domains, with the idea that requirements from both fields would constrain positively future propositions. To limit the scope of the thesis, we focused on body movements (not considering static bodily aspects or other modalities), low level coupling mechanisms and the moderating role of individual differences with the aim to propose proof of concept of virtual human prototypes (rather than complete functional software) embedding full body dyadic interaction models. Our research methodology can be summarized in four main steps. First, models and hypotheses linking social interaction processes and individual differences emerged from a review of the literature in both computer and human sciences. As the identified relevant individual differences appeared barely theoretically associated, our second step aimed at investigating their interrelatedness in a large scale study. Thirdly, bodily interactions were analyzed in two case studies which present application and experimental interests. In both cases, corpuses were collected with full body interacting dyads and individual differences measured. The final phase was to develop virtual human prototypes inspired by previous analyses and based on the collected data. The proposed general model of individual differences was shown to be consistent with real word data (collected by self-report questionnaires): dispositions in pro-social orientations, empathy and emotion regulation were closely related. The two case studies partially confirmed our initial hypotheses: various individual differences modulated the bodily interactive processes. These studies enabled the definition of parsimonious virtual human interactive models. The main critical contribution of the two case studies to the proposed model of individual differences is the clear necessity to take into consideration the task context before drawing any hypotheses. Future directions of research are proposed including an integration of individual differences identified in case studies

Wind power will be an important component of California's aggressive strategies to meet its greenhouse gas reduction targets by the year 2020. However, the costs of integrating wind power's variable and uncertain output are often ignored. I argue that California must take prudent action to understand, minimize, and allocate wind integration costs. A review of numerous studies suggests that for wind penetration levels below 20%, integration costs should remain modest. However, costs are heavily dependent on market structure, and I suggest numerous ways that California can optimize its market design to manage wind integration costs.

El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado.In the past decade, there has been an increasing need for semantic-aware data search and indexing in textual (structured and NoSQL) databases, as full-text search systems became available to non-experts where users have no knowledge about the data being searched and often formulate query keywords which are different from those used by the authors in indexing relevant documents, thus producing noisy and sometimes irrelevant results. In this paper, we address the problem of semantic-aware querying and provide a general framework for modeling and processing semantic-based keyword queries in textual databases, i.e., considering the lexical and semantic similarities/disparities when matching user query and data index terms. To do so, we design and construct a semantic-aware inverted index structure called SemIndex, extending the standard inverted index by constructing a tightly coupled inverted index graph that combines two main resources: a semantic network and a standard inverted index on a collection of textual data. We then provide a general keyword query model with specially tailored query processing algorithms built on top of SemIndex, in order to produce semantic-aware results, allowing the user to choose the results' semantic coverage and expressiveness based on her needs. To investigate the practicality and effectiveness of SemIndex, we discuss its physical design within a standard commercial RDBMS allowing to create, store, and query its graph structure, thus enabling the system to easily scale up and handle large volumes of data. We have conducted a battery of experiments to test the performance of SemIndex, evaluating its construction time, storage size, query processing time, and result quality, in comparison with legacy inverted index. Results highlight both the effectiveness and scalability of our approach.
This study is partly funded by the National Council for Scientific Research - Lebanon (CNRS-L), by the Lebanese American University (LAU), and the Research Support Foundation of the State of Sao Paulo ( FAPESP ). Appendix SemIndex Weighting Scheme We propose a set of weighting functions to assign weight scores to SemIndex entries, including: index nodes , index edges, data nodes , and data edges . The weighting functions are used to select and rank semantically relevant results w.r.t. the user's query (cf. SemIndex query processing in Section 5). Other weight functions could be later added to cater to the index designer's needs.

In order to survive in today's competitive manufacturing markets, manufacturing systems need to adapt at an ever-increasing pace to incorporate new technology which can lower the cost of production, while maintaining quality and delivery schedules. The task of the manufacturing system becomes even more challenging in the quest to use a common approach for different manufacturing plants and ever evolving manufacturing processes for specific plants. This thesis introduces a reference architecture that enables such changes between plants and updates within plants. For this, we use the paradigm of Manufacturing Execution Systems (MES). A developed MES architecture by the National Institute of Standards and Technology (NIST) is used as the standard reference architecture. Its flexibility and scalability is applied to a specific steel melt-shop plant case study. In this case study the standard framework is specified through re-labeling standard data and modules to specifics tailored for the melt process of a generic steel plant. Since steel plants are faced with difficult scheduling and disturbance handling problems, specific intelligent algorithms are developed to deal with these issues through integrating some of the control into the MES. Conclusions as to the success of the algorithms along with supporting data and recommendations of further use for them are also included.

This dissertation contributes to a strand of literature on the economic integration of immigrants in Canada's labour market. My first essay examines the economic return to human capital acquired abroad using an improved identification strategy of foreign education and work experience. My second essay examines whether education-job mismatches, on the part of immigrants, possibly explain their poor labour market outcomes. My final essay provides new evidence on the economic assimilation of U.K. immigrants in Canada over the late 19th and early-20th-century.In my first essay I exploit the enhanced details on education attainment provided in the Survey of Labour and Income Dynamics (SLID) to decompose aggregate human capital variables into more precise measures of foreign and Canadian locations than those employed in related Census-based studies. I find that measurement error associated with using imprecise measures exaggerates the portability (in terms of economic returns) of foreign schooling and the degree of immigrant wage assimilation. However, the virtually zero returns to foreign work experience, commonly found in the literature, cannot be attributed to measurement error. Thus, this dimension of human capital receives virtually no recognition for immigrants and it is mainly responsible for the substantial estimated wage gaps in the standard human-capital-adjusted earnings function.The contribution of my second essay is an investigation of the importance of education-job mismatches in explaining the poor labour market outcomes observed for immigrants to Canada. Immigrants have a modestly lower incidence of working in jobs related to their education than do the Canadian-born, and there is a sizable wage penalty for working in unrelated jobs. The lower incidence of matching, found among immigrant workers, can explain a sizable portion of their lower returns to foreign education credentials, and also the immigrant-native wage gap among university educated workers. By contrast, foreign education and work experience acquired abroad is not discounted in the Canadian labour market for immigrants who are successfully matched.My final essay examines the economic assimilation of pre-war U.K. immigrants using recently digitized samples of the 1901 and 1911 censuses. These nationally representative samples allow for a more comprehensive examination of immigrant assimilation than existing published evidence which is limited to cross-sectional samples of Montréal and Toronto. Estimates of within-cohort earnings growth show that these newcomers, despite their cultural similarities with the Canadian-born, experienced sizable earnings disadvantages upon arrival coupled with slow subsequent earnings growth. However, most immigrant cohorts achieved earnings parity with comparable Canadian-born workers over their working life unlike that found for Montréal and Toronto. Thus, although the government's desire was to attract the most industrious and hard working immigrants, arrivals from the British Isles may have been negatively selected in terms of unobservable labour market characteristics.Cette thèse contribue à la littérature qui examine l'intégration des immigrants au marché de travail Canadien. Le premier essai étudie le retour au capital humain acquis à l'étranger sur le marché de travail Canadien utilisant des stratégies améliorées d'indentification de ce dernier. Mon deuxième essai examine des conséquences économiques de l'absence de la correspondance parfaite des professions que les immigrants au Canada peuvent obtenir avec leurs disciplines d'études. Mon troisième essai produit des faits stylisés nouveaux au sujet de l'intégration des immigrants de provenance du Royaume-Uni au Canada durant la fin du 19ème au début du 20ème siècle.Dans mon premier essai j'exploite des détails améliorés de l'Enquête sur la dynamique du travail et du revenu à fin de décomposer le capital humain a des portions acquises à l'étranger et des portions acquises au Canada. Je trouve que l'erreur de mesure associée à l'emploi des indicateurs imprécis avait causé la sous-estimation de l'écart entre le retour sur le capital humain acquis à l'étranger et celui acquis au Canada dans les études précédentes. Je trouve, en revanche, que le capital humain acquis à l'étranger reçoit un retour nul au Canada et cela explique la quasi-totalité de l'écart de revenu entre les immigrants et les natifs.Mon deuxième essai examine l'importance de la correspondance imparfaite entre les disciplines d'études et la profession des immigrants au Canada pour expliquer leurs performances économiques inferieures. Je trouve que cette correspondance imparfaite est un peu plus fréquente chez les immigrants et qu'elle a cependant des conséquences négatives non-négligeables sur le salaire. Cette probabilité plus faible que des immigrants puissent travailler dans un domaine proche de leurs disciplines d'étude explique une portion considérable de l'écart de salaire entre les immigrants et les natifs comparables ainsi que leurs retours du capital humain plus bas. Mon troisième essai porte un regard nouveau sur la question d'intégration des immigrants de provenance du Royaume-Uni durant la fin du 19ème siècle au début du 20ème siècle en utilisant des données récemment numérisées des recensements de l'époque. L'échantillon que j'utilise dans cette recherche représente la distribution nationale de ces immigrants contrairement aux échantillons auparavant utilisés qui portaient seulement sur les immigrants résidant au Québec et en Ontario. Mes estimations montrent que ces immigrants, malgré leur similarité culturelle avec les natifs, ont subi un écart du salaire considérable ainsi qu'un taux de croissance du salaire plus bas en comparaison avec les natifs. Cependant, je trouve que la plupart de ces immigrants ont ultimement arrivé à un salaire équivalent aux natifs comparables durant leurs vies professionnelles. Je trouve aussi que le gouvernement, malgré son intention, a échoué d'attirer les immigrants industrieux et entreprenants en raison des facteurs inobservables conduisant à une sélection peu efficiente de ces immigrants.

Business-wide integration is a key strategic objective for survival in a global market place. The objective of the work presented in this thesis was to conduct a detailed study of business integration methods with a view to identifying development areas and developing the necessary methods, procedures and tools to address these gaps. Following a literature review the following development needs were identified: - -A Reference Model - An Audit Method -A Methodology The latter part of this thesis presents, in detail, the Reference Model, the Audit Method and the Methodology which' has been developed to fulfil the gaps identified. The Reference Model identifies six performance areas and criteria which an organisation would need to fulfil to achieve business-wide integration. The Methodology provides necessary framework, tools and techniques to achieve the performance criteria specified within the Reference Model. The Methodology consists of six main phases which ensures that the business vision, objectives and strategy are deployed through various functions down to operational processes. This is achieved through the use of an integrated set of performance measures. The Audit Method provides a set of procedures to measure an organisations performance against the criteria identified within the Reference Model. It is also used to measure the effectiveness of the methodology towards the achievement of the Reference Model. The application of the Methodology is illustrated through three different case studies. All three case studies, through the Audit Method, demonstrate that the application of the Methodology has resulted in considerable and measurable improvements in the levels of integration. Throughout the thesis emphasis has been placed on the research methods employed. The thesis concludes with a review of the work done and the research methods employed.

This thesis considers the use of three-phase voltage and current source inverters as interfacing units for renewable power, specifically photovoltaic (PV) into the ac grid. This thesis presented two modulation strategies that offer the possibility of operating PV inverters in grid and islanding modes, with reduced switching losses. The first modulation strategy is for the voltage source inverter (VSI), and exploits 3rd harmonic injection with selective harmonic elimination (SHE) to improve performance at low and high modulation indices, where the traditional SHE implementation experiences difficulties due to pulse dropping. The simulations and experimentation presented show that the proposed SHE allows grid PV inverters to be operated with less than a 1kHz effective switching frequency per device. This is vital in power generation, especially in medium and high power applications. Pulse dropping is avoided as the proposed modified SHE spreads the switching angles over 90°, in add ition increasing the modulation index. The second proposed modulation strategy, called direct regular sampled pulse width modulation (DRSPWM), is for the current source inverter (CSI). It exploits a combination of forced and natural commutation imposed by the co-existence of an insulated gate bipolar transistor in series with a diode in a three phase current source inverter, to determine device dwell times and switching sequence selection. The DRSPWM strategy reduces switching frequency per device in a CSI by suspending each phase for 60°, similar to VSI dead-band, thus low switching losses are expected. Other benefits include simple digital platform implementation and more flexible switching sequence selection and pulse placement than with space vector modulation. The validity of the DRSPWM is confirmed using simulations and experimentation. This thesis also presents a new dc current offset compensation technique used to facilitate islanding or grid operation of inverter based distributed generation, with a reduced number of interfacing transformers. The proposed technique will enable transformerless operation of all inverters within the solar farm, and uses only one power transformer at the point of common coupling. The validity of the presented modulation strategies and dc current offset compensation technique are substantiated using simulations and experimentation.

The process of European integration has had an impact on the cultural patterns of the Member States but it is not inevitably eroding national identities. By analysing the way in which the ability of the Member States to pursue a national language policy is restricted by the free movement principles and by analysing the cultural action taken at the supranational level it is argued that the European Community is genuinely committed to protecting and maintaining its cultural diversity. However, the political sensitivity which surrounds any impingement of national cultural sovereignty coupled with the fact that the objective of European integration remains primarily economic has significantly restricted the European Community's room to manoeuvre in the cultural sphere. A re-ordering of Community values and priorities would prevent non-economic interests, such as cultural interests, from being consistently trumped by those which are of an economic nature. In the meantime, the European Community must expressly and unequivocally state its commitment to cultural diversity, for example, in a Community Cultural Charter. Further, it is asserted that tangible cultural homogeneity is not required in the development of the overarching European identity necessary to legitimise the future construction of Europe.

Member Countries of the Andean Community (ANCOM) have established a supranational legal regime applicable to intra and extra-subregional air transport activities: the Andean Subregional Air Transport Integration system. This regime was established by Decisions 297 and 320 and was based on the Colombia-Venezuela Bilateral Air Transport Agreement. It revolutionizes the status quo regarding air transport. The new regime adopts the principles of multiple designation of air carriers, free determination of frequencies and capacities for scheduled air services performed with the Subregion, and complete liberalization for non-scheduled air services. It creates an "Andean subregional market" and promotes the establishment of a "common" position for negotiating intra and extra-regional fifth freedom.Member Countries have been unresponsive in updating their bilateral agreements vis-a-vis the regime set by Decisions 297 and 320. This situation makes the application and healthy development of the Andean Subregional Air Transport Integration process difficult.
In order to avoid these difficulties, Member Countries shall apply the supranational principles contained in Decisions 297 and 320 and update their bilateral agreements. (Abstract shortened by UMI.)

Computing marginal likelihoods to perform Bayesian model selection is a challenging task, particularly when the models considered involve a large number of parameters. In this thesis, we propose the use of an adaptive quadrature algorithm to automate the selection of the grid in path sampling, an integration technique recognized as one of the most powerful Monte Carlo integration statistical methods for marginal likelihood estimation. We begin by examining the impact of two tuning parameters of path sampling, the choice of the importance density and the specification of the grid, which are both shown to be potentially very influential. We then present, in detail, the Grid Selection by Adaptive Quadrature (GSAQ) algorithm for selecting the grid. We perform a comparison between the GSAQ and standard grid implementation of path sampling using two well-studied data sets; the GSAQ approach is found to yield superior results. GSAQ is then successfully applied to a longitudinal hierarchical regression model selection problem in Multiple Sclerosis research.Using an identity arising in path sampling, we then derive general expressions for the Kullback-Leibler (KL) and Jeffrey (J) divergences between two distributions with common support but from possibly different parametric families. These expressions naturally stem from path sampling when the popular geometric path is used to link the extreme densities. Expressions for the KL and J-divergences are also given for any two intermediate densities lying on the path. Estimates for the KL divergence (up to a constant) and for the J-divergence, between a posterior distribution and a selected importance density, can be obtained directly, prior to path sampling implementation. The J-divergence is shown to be helpful for choosing importance densities that minimize the error of the path sampling estimates.
Finally we present the results of a simulation study devised to investigate whether improvement in performance can be achieved by using the KL and J-divergences to select sequences of distributions in parallel (population-based) simulations, such as in the Sequential Monte Carlo Sampling and the Annealed Importance Sampling algorithms. We compare these choices of sequences to more conventional choices in the context of a mixture example. Unexpected results are obtained, and those for the KL and J-divergences are mixed. More fundamentally, we uncover the need to select the sequence of tempered distributions in accordance with the resampling scheme.

Cities evolve in a rhizome-like fashion interconnected nodes accelerating the flow of information, rate of innovation, and the accumulation of wealth, but also making apparent new inequalities and informal economies. Since the '70s, the green and feminist movements, and self-help housing, are challenging the duality of Western discourse, scientific methods, and the separation between working and living. The creation of productive livelihoods and self-sufficient households---including local food production---can help restore local cultural and ecological habitats in the urban milieu. Sustainability is redefined as maintaining, improving and restoring local household productivity levels. This multi-disciplinary study considers the evolution of technological, social and artistic innovation; it considers housing as a fluid interface between human and biological systems, thus a social organization defined by its human ecology. Overall productivity performance is measured in terms of cultural and biological diversity, and leisure time produced.

Neural control of behaviour during development is a complicated orchestration of gene expression, neuronal differentiation, axonal projection, modification of intrinsic membrane properties and connectivity of neural circuits. The studies in this thesis combined genetic, molecular, and physiological assays to investigate neuromodulation, reticulospinal contribution, and neurogenic programming of the limited behavioural repertoire of developing zebrafish. Maturation of early swimming, the change from infrequent episodes of swim bursts to a sustained “beat-and-glide” pattern, was mediated by serotonergic modulation of the spinal network. Serotonergic immunoreactivity was first detected in neurons located in the ventral spinal cord at 2 days post-fertilization (dpf). A second population of serotonergic neurons was detected in the hindbrain but these remained isolated from the spinal cord in the stages studied (2-4 dpf). Serotonergic modulation of the fictive swim pattern only occurred in 4 dpf larvae, the time when “beat-and-glide” swimming emerges, but not in younger larvae. Application of serotonin did not affect properties of activity (beat-and-glide) periods, but instead reduced the periods of inactivity between activity periods. Hindbrain reticulospinal (RS) neurons displayed four types of activity patterns during simultaneous spinal motoneuron recordings of fictive swimming activity in zebrafish larvae. RS neurons generated these activity patterns even in the absence of ascending spinal input during development. The spinal CPG network, however, failed to produce rhythmic oscillations in the presence of N-methly-d-aspartate when it developed without descending RS input, indicating that the latter are necessary for development of CPG activity. In addition to swimming, zebrafish larvae also produce startle responses in reaction to potential danger, a behaviour that is missing in hi472 mutant larvae. hi472 mutation disruptLe contrôle neuronal du comportement durant le développement dépend de l'intégration complexe de l'expression génétique, de la différentiation neuronale, de la projection axonale, de la modification des propriétés membranaires intrinsèques et de la connectivité des circuits neuronaux. Les études décrites dans cette thèse regroupent des approches génétiques, moléculaires et physiologiques afin d'examiner la neuromodulation, la contribution du système réticulospinal et la programmation neurogène afin d'étudier le répertoire limité des comportements du poisson zébré en voie de développement. Vers la quatrième journée du développement les larves changent leur comportement de natation, ils passent d'épisodes rares et de courte durée de natation en un patron maintenu de type nage-et-glisse, ou le poisson exécute quelques fortes contractions de la queue suive d'une période de glisse. Nous avons démontré cette maturation de la natation précoce, est due à la modulation sérotoninergique du réseau spinal. L'immunoréactivité sérotoninergique est détectée initialement chez une population de neurones situés dans la moelle épinière ventrale à 2 jours post-fertilisation (jpf). Une deuxième population de neurones sérotoninergiques a été détectée dans le tronc cérébral mais celle-ci ne projette pas d'axones vers la moelle épinière aux stades étudiés (2-4 jpf). La modulation sérotoninergique du patron de natation fictive se manifeste seulement chez des alevins de 4 jpf, au moment ou la natation nage-et-glisse se déploie, mais pas chez des alevins plus jeunes. Nous avons aussi démontré que l'application de sérotonine n'a aucun effet sur les propriétés des épisodes de nage active mais par contre, résulte en une réduction de la durée périodes d'inactivité entre les épisodes de nage-et glisse.

This masters thesis analyzes telecommunications policies in Argentina, Brazil, Paraguay and Uruguay, and relates these to the ongoing economic integration of these countries within MERCOSUR. To this end, a survey of the telecommunications sector in each of the MERCOSUR countries, depicting the main features of their respective regulatory framework, competition policy, and universal service goals is provided in Part II. Part III briefly describes the GATS/BTA framework and comments on MERCOSUR countries' commitments towards market liberalization. In Part IV, MERCOSUR's legal and institutional framework, along with the common initiatives that have been taken with respect to the telecommunications sector, are considered. By way of conclusion, Part V proposes further reflections on theoretical approaches aimed at framing telecommunications normativity in consideration of its dynamic interaction with globalization and integration in the context of MERCOSUR.

The integration of immigrants into host societies has been a topic of longstanding interest in the sociology of migration, whereas the study of transnationalism has only emerged in the last few years. Globalization, fueled by the rapid development of transportation and communication technologies, has been one of the principal factors in the rise of transnationalism. The aim of this study is to clarify the links between the immigrants' integration into the host society and the transnational activities in which they get involved.The initial hypothesis of this study was that immigrants' involvement in narrow transnational activities is linked to their weaker integration into Quebec society. To test this hypothesis, a series of interviews was conducted with members of the Dominican community of Montreal. These Dominicans were involved in varying levels of transnational activities within political, economic, and cultural spheres. The interviews were aimed at determining the integration process experienced by the different interviewees.
The results of this study showed, in contrast to the hypothesized predictions, that involvement in transnational activities was not linked to lesser levels of integration. In fact, the Dominicans involved in the most intensive transnational activities revealed a capacity to integrate into the receiving society as easily as other Dominicans, often showing a greater dynamism in their integration. Involvement in intensive transnational activities seems to show a capacity on the part of some immigrants to grow and develop in two universes at the same time, that of the receiving and that of the sending society.

Mechanisms to share information from Mechanical Computer Assisted Design (MCAD) to simulation model have been demonstrated using various approaches. However, in all cases the information sharing is unidirectional - from the MCAD to Multi-Body Systems (MBS) simulation - which lacks the bidirectional mapping required in a concurrent engineering context where both models need to develop in parallel while remaining consistent.We present a modelling library and a model mapping that permits and encourages parallel development of the mechanical assembly in both the MBS simulation and MCAD environments while supporting both bidirectional initial full transfer and incremental updates. Furthermore, with the adopted approach and with a careful selection of the simulation language, MCAD parts can be extended with non-mechanical behaviour in the simulation tool.Des mécanismes pour partager l'information entre un modèle CAD et un modèle de simulation ont été démontrés utilisant divers approches. Pourtant, dans tous les cas, le partage d'information était unidirectionnel - allant du modèle CAD vers le modèle de simulation - donc ne possédant pas les qualités bidirectionnelles nécessaires dans le contexte de l'ingénierie collaborative ou les modèles doivent rester consistantes en permanence.Nous présentons notre librairie de modélisation et de transformations entre modèles qui permettent et encouragent le développement parallèle de l'assemblage mécanique dans les deux environnements de simulation de conception. Notre approche supporte le partage et la synchronisation des deux modèles dans les deux sens et de façon incrémentale si nécessaire. En complément, avec l'approche que nous avons adopté, les modèles mécaniques peuvent être associés a des modèles comportementales non mécanique dans l'outil de simulation.

Currently, several numerical methods have been provided for 2-D and 3-D integrations. But there is insufficient analysis reported on the overall performances of the available methods for fundamental electromagnetics problems. A complete evaluation is presented to discover the best ways of integrating these electromagnetics problems through benchmark performance studies of the available methods focussing on the integration accuracy, the location of sampling points, and the influence of integration domain refinement schemes. To meet this goal, three benchmark problems have been designed and evaluated. Accurate and reasonably cost-efficient integration methods are recommended.

This work involves developing a method to numerically integrate smooth functions over a smooth, bounded, convex set in three dimensional Euclidean space. The integrand is assumed to have continuous sixth partial derivatives, and the boundary of the set is assumed to be a surface with bounded, continuously differentiable curvatures.The scheme consists of using an orthogonal mesh of width h to decompose the region into some standard group of geometrical subregions for which numerical integration formulae are developed. Error formulae for these standard subregions are derived by approximating the integrand with its local Taylor polynomial approximation.
The method is adaptive in that only those subregions with insufficiently small error are further subdivided. The global error is shown to be of the fourth order in h, ensuring that subsequent refinements will result in a satisfactory total error. The scheme is illustrated with examples run on a programme written in the language UBASIC.

This thesis reports on an information behaviour investigation into refugee integration, undertaken to understand how refugees navigate complex integration processes and systems. The aim was to find person-centred information needs, relationships and sources that could inform the design of person-centred integration systems. The study was carried out through an interdisciplinary synthesis of academic literatures and professional practice. Theories of information behaviour were synthesised with principles in refugee integration into a theoretical framework founded on Dervin's sense-making methodology. The research data were collected by interviews and observations, such that the observation data substantiated interview findings. A diverse population of refugees were interviewed directly and observation of service provision was recorded during a volunteer role with the Scottish Refugee Council. The data analysis was process-driven and dynamic, using an iterative process of thematic coding. This resulted in pertinent institutional dimensions being factored into the identification of information needs. The research findings culminated in an information needs matrix - a navigational guide with implications for research, policy and practice. The study found connections between people, information and sociological needs as refugees navigate integration processes and systems. In addition, the experiences of navigating integration systems were tied to specific times, places and human conditions. This relationship resulted in the information needs matrix, which encompasses the complexities of navigating integration systems and points to refugee integration being as much an information issue as it is a sociological one.

Diese Arbeit widmet sich der Simulation von elektrischen/elektronischen Schaltungen welche um elektromagnetische Bauelemente erweitert werden. Im Fokus stehen unterschiedliche Kopplungen der Schaltungsgleichungen, modelliert mit der modifizierten Knotenanalyse, und den elektromagnetischen Bauelementen mit deren verfeinerten Modell basierend auf den vollen Maxwell-Gleichungen in der Lorenz-geeichten A-V Formulierung welche durch Finite-Integrations-Technik räumlich diskretisiert werden. Eine numerische Analyse erweitert die topologischen Kriterien für den Index der resultierenden differential-algebraischen Gleichungen, wie sie bereits in anderen Arbeiten mit ähnlichen Feld/Schaltkreis-Kopplungen hergeleitet wurden. Für die Simulation werden sowohl ein monolithischer Ansatz als auch Waveform-Relaxationsmethoden untersucht. Im Mittelpunkt stehen dabei Zeitintegration, Skalierungsmethoden, strukturelle Eigenschaften und ein hybride Ansatz zur Lösung der zugrundeliegenden linearen Gleichungssysteme welcher den Einsatz spezialisierter Löser für die jeweiligen Teilsysteme erlaubt. Da die vollen Maxwell-Gleichungen zusätzliche Ableitungen in der Kopplungsstruktur verursachen, sind bisher existierende Konvergenzaussagen für die Waveform-Relaxation von gekoppelten differential-algebraischen Gleichungen nicht anwendbar und motivieren eine neue Konvergenzanalyse. Auf dieser Analyse aufbauend werden hinreichende topologische Kriterien entwickelt, welche eine Konvergenz von Gauß-Seidel- und Jacobi-artigen Waveform-Relaxationen für die gekoppelten Systeme garantieren. Schließlich werden numerische Benchmarks zur Verfügung gestellt, um die eingeführten Methoden und Theoreme dieser Abhandlung zu unterstützen.This work is devoted to the simulation of electrical/electronic circuits incorporating electromagnetic devices. The focus is on different couplings of the circuit equations, modeled with the modified nodal analysis, and the electromagnetic devices with their refined model based on full-wave Maxwell's equations in Lorenz gauged A-V formulation which are spatially discretized by the finite integration technique. A numerical analysis extends the topological criteria for the index of the resulting differential-algebraic equations, as already derived in other works with similar field/circuit couplings. For the simulation, both a monolithic approach and waveform relaxation methods are investigated. The focus is on time integration, scaling methods, structural properties and a hybrid approach to solve the underlying linear systems of equations with the use of specialized solvers for the respective subsystems. Since the full-Maxwell approach causes additional derivatives in the coupling structure, previously existing convergence statements for the waveform relaxation of coupled differential-algebraic equations are not applicable and motivate a new convergence analysis. Based on this analysis, sufficient topological criteria are developed which guarantee convergence of Gauss-Seidel and Jacobi type waveform relaxation schemes for introduced coupled systems. Finally, numerical benchmarks are provided to support the introduced methods and theorems of this treatise.

This thesis presents a survey of the development of economic growth theory, including the latest developments in the relationship between international economic integration through international flows of goods and/or knowledge and endogenous economic growth. Based on the following literature review, a new and more reasonable model for the research and development (i.e., the R&D) sector--a sector which is considered the source of long-run growth--is offered in order to develop and improve the framework built by Rivera-Batiz and Rome (1991), i.e. the RBR model. This new model will make the RBR framework more complete and rational. In this new model, it is proved that any form of economic integration will increase the long-run rate of growth, and these results are compared with those of the RBR. Moreover, Devereux and Lapham's efforts to find some dynamic analysis along the transitional path under two different situations: knowledge flows only, and both goods and knowledge flows, are continued in the same model. It is found that when only knowledge is allowed to flow across borders, economic integration generates corner solutions for the production of the R&D sector, while this does not happen when complete goods and knowledge flows exist. However, the real balanced growth rates in these diverse situations are higher than they are in autarky.

The Asia-Pacific Economic Cooperation (APEC) is a regional economic forum composed of 21 member economies of diverse cultural heritage and varying levels of economic development. By deliberately avoiding to become a formalized free trade arrangement like the EU or the NAFTA, APEC has committed to the principle of "open regionalism", meaning that liberalization achievements are not preferential to APEC members only. APEC has evolved rapidly since its formation in 1989. Begun as an informal dialogue group, APEC has expanded to become the primary vehicle for promoting open trade and economic cooperation in the Asia-Pacific region.APEC is also one of the few multilateral economic organizations that actively embraces China as a committed partner in the global trade and investment dialogue. Economic reform and open door policies implemented over the last two decades have transformed China from a closed economy into a major trading power. China, which for more than a decade has unsuccessfully sought to join the GATT/WTO, finds APEC to be of immense symbolic and practical value. As a major member of APEC, China has made constructive role in the APEC process. With its dynamic economic growth and continuing economic reforms, China is poised to play an even greater role in APEC in the near future.

This thesis compares multiculturalism policies in Canada and Sweden, emphasising immigrant and ethnic minority political participation and representation. The analysis follows a structural approach, looking at, in each country, the level of "institutional inclusiveness" or the degree of openness to cultural diversity. Though Sweden offers better formal conditions for integration, Canada fares much better in incorporating immigrants and ethnic minorities in its citizenry. This suggests that Canadian institutions are more reflective of the principles of multiculturalism. Still, in both countries, visible minorities face more obstacles than other groups in the process of integration.

The integration of students with an intellectual disability has been a long standing issue and goal in special education. It is usually assumed that such educational integration will terminate following completion of high school. There are examples however, where persons with an intellectual liability have participated in higher education. One example of an integrated program has been implemented at a junior college in Ste. Anne de Bellevue, Quebec. This is a work-study type of program in which students 18-21 years of age follow a specific curriculum in the closed classroom and also participate in certain regular college classes, including physical education.The purpose of the present study was to investigate this unique program with particular emphasis on physical education. More specifically, it was the intent to measure the perceptions of persons directly involved with the program on such variables as social acceptance, social interaction, self-concept, motor performance, peer performance, attitude, expectations, and perceptions. A questionnaire was distributed to subjects in four groups: students, peers, physical educators, and parents. Mean response scores from each group were reported for each variable. Results indicated a general positive perception regarding the integrated program from all groups.

Economic integration and foreign direct investment were adopted by developing countries particularly in Africa, as strategies for economic development. For these countries, economic integration became not only a tariff issue, but a strategy for development; hence the term "developmental regionalism". This thesis is a study of the concept of developmental regionalism in West Africa. It concentrates on the Economic Community of West African States (ECOWAS), which was formed in 1975.It is argued that as a strategy for development, the ECOWAS integration effort was inadequate because of undue reliance on tariff reductions--- so called "negative integration" measures. It is suggested that to facilitate a more cohesive integration program, countries in the region ought to adopt positive integration measures in the form of common policies on money and payments, industrialization and most significantly, a common policy on investments.
With respect to investment regulation, it is my argument that because liberalization of investment laws at the national level failed to attract the desired flow of foreign investment to the region, ECOWAS Member States ought to harmonize their regulatory framework with a view to ultimately adopting a single legal regime for international investment.
As a framework for analysis, I adopt the criteria of economic efficiency. This is a cost/benefit analysis of the transformations that occur as the result of contractual transactions. Where the costs to the parties exceed or are likely to exceed the benefits of the transaction, it is said to be inefficient. Using these criteria, I argue that in order to inject a level of fairness in investor/host state relations, and to avoid the costs of FDI to host societies exceeding the gains therefrom, international law ought to make binding prescriptions to govern corporate conduct. Based on this reasoning, I suggest a framework for improving the investment climate in West Africa.

Molecular Dynamics simulations often involve the numerical integration of pair-wise particle interactions with a constant, step size method. Of primary concern in these simulations is the introduction of error in velocity statistics. We consider the simple example of the symplectic Euler method applied to two-particle collisions in one dimension governed by linear restoring force and use backward error analysis to predict, these errors. For nearly all choices of system and method parameters, the post-collision energy is not conserved and depends upon the initial conditions of the particles and the step size of the method. The analysis of individual collisions is extended to predict energy growth in systems of particles in one dimension.

This study explores the relationships between the integration experiences of adolescent newcomers in one francophone secondary school in Montreal and the current policies and programs related to educational integration. The research draws on observations and participants' descriptions and insights to address three principal questions: How is integration experienced by adolescent newcomers in a francophone school in Montreal? How do these students' experiences inform our understanding of the relationships among host (second) language learning/teaching, integration, and identity construction? What are the implications of these newcomer students' integration experiences for educational theories, policies and programs/practices that target such newcomers? These questions emerge from a consideration of theories of identity construction current in a variety of disciplines.The study offers an overview of Quebec's past and present immigration and integration policies and programs. It considers those policies in light of identity theory and, more specifically, focuses on the relationships between language learning, integration, and identity in the experience of adolescent immigrants within a francophone secondary school in Montreal. Based on interviews and participant observation conducted over 15 months, the study describes the ways in which the participants' integration and identity are shaped by school discourses and the standardizing imperative of most North American educational institutions. Findings suggest that the participants resist the school's discourses in order to assert themselves dialogically and relocate their sense of identity in their host society. However, the dialogic relationships that the students are able to establish with and within the school discourses are imbalanced, leaving several students to feel dislocated both physically and psychically throughout the study. The study indicates that a distributed notion of the Self might improve theory, policy, and pedagogy related to newcomer integration. Finally, specific suggestions are made for building on current educational-integration research and practice.

Power grids are changing significantly with the introduction of large amounts of renewable energy (especially wind) into the system. Integration of wind energy into the grid is challenging as, firstly it increases penetration stresses when compared to conventional generation as the wind is intermittent and fluctuates in power output. Secondly, most of the wind farms are located in offshore or rural areas which have good wind conditions. The grid in these regions is not normally strong. Most of the modern variable speed wind turbines use voltage source converters (VSCs) for grid integration. However, integrating VSCs to weak power grids will cause instability when a large amount of active power is transferred to the grid. In this thesis, the integration of wind farms to very weak power grids is investigated. A multiple input, multiple output (MIMO) model of the grid side VSC of a wind turbine is developed in the frequency domain in which the d-axis of the synchronous reference frame (SRF) is aligned with the grid voltage. Then, this model has been used as the basis for modelling the multiple parallel converters in the frequency domain. In this thesis, to improve the stability of the very weak grid connected of VSCs, a control method based on the d- and q- axis current error is introduced. This controller compensates the output angle of the phase locked loop (PLL) and the voltage amplitude of the converter. Using this controller, full rated active power transfer and fault ride-through are achieved under very weak grid connection. Furthermore, a stabiliser controller based on virtual impedance is proposed in this thesis to achieve stable operation of a very weak grid connected VSC. This stabilising control method enables the VSC to operate at full power and to ride-through faults under very weak grid conditions. Based on this principle, an external device is proposed that can be utilised and connected to a weak point of the grid to allow a large amount of VSC interfaced power generation (e.g. wind power) to be connected to the grid without introducing stability issues.

Light emitting polymers (LEPs) are a promising category of organic materials for photonic applications owing to their potential for simple fabrication and availability of materials emitting across the whole visible spectrum. LEPs are already exploited commercially in the case organic light emitting diodes and their interesting properties for colour conversion and as laser gain material are under investigation. To keep the LEPs' benefit of simple and low-cost fabrication, integration onto inorganic semiconductor devices such as in particular gallium nitride light emitting diodes (LEDs) is an important research topic. In this thesis, developments towards integration of organic devices onto micro-pixellated ip-chip LEDs are presented. This particular format may be beneficial for applications such as displays, various sensing schemes and data transmission owing to spatio-temporal control, high modulation bandwidths and potential for simple integration with complementary meta l oxide semiconductor electronics. The properties of LEP films as optical gain medium were assessed on smooth and corrugated substrates. In the former case, random laser action (RL) was observed which is attributed to the high optical gain delivered by these materials. Arguments are presented suggesting that RL may be very common in high gain media. In the latter case, mechanically flexible distributed feedback lasers were fabricated in a very simple way and their properties including operational lifetime were characterised. Nano-patterned LEP films for colour conversion of LED light exhibited strong modification of the LEP emission due to the photonic crystal (PhC) effect of the periodic pattern. PhCs allow tailoring of the emission properties by appropriate design of the nano-pattern and they can be created relatively easy in organic films. Furthermore, the modulation bandwidth of an organic PhC film excited by micro-LEDs was measured to be 168 MHz and was mainly limited by the inorganicLED. This underpins the potential of LEPs for communications applications. The suitability of micro-LEDs in flip-chip format as pump source for organic semiconductor lasers was investigated. For this purpose, stripe-shaped arrays of micro-LEDs were developed that were employed for the demonstration of the first micro-LED pumped polymer laser.

Auditory-motor skills such as speaking or playing a musical instrument require skill in processing auditory outcomes and performing actions that produce those outcomes. A growing body of evidence suggests that perception and production components of auditory-motor skill are integrated by reciprocal auditory-to-motor and motor-to-auditory interactions. Much remains unknown about how complex auditory sequences map to complex movement sequences such as those required of speech or music performance. Less still is known about how auditory-motor interactions influence the way skilled performers learn and remember novel auditory-motor sequences. The research described in this thesis examined these questions in the context of music performance. Music performance is a common and complex auditory-motor behavior that presents a useful model for examining human auditory-motor capabilities as it requires precise control of both pitch and temporal sequences of events. Three studies examined how auditory-motor interactions influence the way skilled musicians map pitch and temporal sequences to movements and the way musicians learn and remember music. The first study examined how auditory pitch and temporal sequence structure in music engage motor neural networks in auditory-motor interactions (Chapter 2). This study revealed motor networks that are sensitive to both pitch and temporal structure when musicians listen to and subsequently perform music. This finding suggests that the motor system integrates multiple dimensions of auditory sequence structure when performers map auditory sequences to motor sequences. The second study examined how performers use auditory and motor information to learn auditory sequences (Chapter 3). This study revealed that musicians better recognize auditory sequences that they hadlearned while producing them with auditory feedback than while hearing them only, indicating that motor learning facilitates subsequent auditory memory for skilled performers. The third study examined how individual differences in auditory and motor imagery abilities influence the way musicians learn novel music and subsequently remember that music (Chapter 4). This study revealed that auditory imagery abilities help performers learn novel music by compensating for missing sound and reducing sensitivity to interfering information; auditory imagery abilities also help performers recall music during performance with greater temporal regularity. Overall, these results suggest that auditory imagery abilities aid learning and subsequent recall of music differently. Together, these studies illuminate how auditory-motor integration functions in skilled performance and how it contributes to auditory-motor sequence learning and memory.Certaines habiletés auditivomotrices, telles que parler ou jouer d'un instrument de musique, requièrent des compétences particulières sur les plans du traitement auditif des sons produits et de la production des actions menant à l'émission de ces sons. À cet égard, un nombre croissant de preuves empiriques suggère que les composantes de perception et de production des habiletés auditivomotrices s'incèrent à l'intérieur d'interactions réciproques entre le système auditif et le système moteur. Plusieurs questions concernant la façon dont des séquences auditives complexes s'alignent avec des séquences complexes de mouvements, telles que retrouvées dans la parole ou les performances musicales, demeurent néanmoins irrésolues. Notamment par rapport à la façon dont les interactions entre les systèmes auditif et moteur influencent l'apprentissage et la rétention de nouvelles séquences auditivomotrices chez des executants compétents. Les recherches décrites dans cette thèse visent à aborder ces questions dans le contexte de performances musicales. En effet, étant donné qu'elles requièrent un contrôle précis de la hauteur du son et de la sequence temporelle des événements, les performances musicales sont des comportements auditivomoteurs communs et complexes représentant un modèle avantageux dans l'examen des capacités auditivomotrices. Trois études sont proposées afin d'examiner l'influence des interactions entre les systèmes auditif et moteur sur la façon dont des musiciens compétents alignent la hauteur sonore et les sequences temporelles avec les mouvements requis lors de performances musicales, de même que sur la façon dont ils apprennent et retiennent une séquence musicale. La première étude examine la manière dont la hauteur sonore et la structuretemporelle d'une séquence musicale engagent certains réseaux neuronaux du système moteur sur le plan des interactions auditivomotrices (Chapitre 2). Cette étude révèle que les réseaux du système moteur sont sensibles à l'intensité sonore et à la structure temporelle lorsque des musiciens écoutent et jouent de la musique. Ces résultats suggèrent que le système moteur intègre de multiples dimensions relatives à la structure de la séquence auditive lorsque ces sequences auditives sont alignées avec des séquences motrices lors de performances musicales. La deuxième étude examine l'utilisation des informations auditives et motrices dans l'apprentissage de séquences auditives (Chapitre 3). Cette etude révèle que les musiciens reconnaissent mieux les séquences auditives qu'ils ont eu à apprendre en les jouant avec rétroaction auditive, par rapport à celles qu'ils ont uniquement eu à écouter. Ces résultats indiquent que l'apprentissage moteur facilite la mémorisation d'information auditive chez les exécutants compétents. La troisième étude examine l'influence des différences individuelles sur le plan des habiletés d'imagerie auditive et motrice, sur l'apprentissage de nouvelles séquences musicales et sur le rappel de ces mêmes séquences (Chapitre 4). Cette étude révèle que les habiletés d'imagerie auditive aident les exécutants à apprendre de nouvelles séquences musicales en compensant pour les sons manquants, de même qu'en réduisant l'interférence liée à l'informations non pertinente; les habiletés d'imagerie auditive améliorent également le rappel de séquences musicales lors de performances comportant une plus grande régularitétemporelle. De manière générale, ces résultats suggèrent que les habiletés d'imagerie auditive aident différemment à l'apprentissage de nouvelles sequences musicales et à leur rappel. Ensemble, ces études illustrent le fonctionnement des intégrations auditivomotrices chez les exécutants compétents, ainsi que leur contribution à l'apprentissage et à la mémorisation de séquences auditivomotrices.

The term upscaling and determination of pseudo curves, or effective parameters, used on a coarse-scale simulation grid are related to the complex and extensive problems associated with reservoir studies. The primary strategy mainly focuses on having a good physical and practical understanding of the particular processes in question, and an appreciation of reservoir model sensitivities. Thus the building of the reservoir simulation models can be optimally determined.By concentrating on the modelling and upscaling gas injection for Enhanced Oil Recovery (EOR) process, which includes Interfacial Tension (IFT) and the amicability effect, a new effective and efficient algorithm of upscaling will be investigated and determined by using several upscaled parameters. The sensitivities of these determined coarse scale parameters (i.e. porosity, absolute and relative permeability and capillary pressure), will also be studied through a history matching of the existing field.

Despite great advances in our understanding of the human immunodeficiency virus (HIV) life cycle, the mechanisms that underlie the progression of HIV from cellular entry of the viral core to stable integration of the provirus are poorly understood. Sites of integration of the HIV provirus are distributed along the full length of actively transcribed genes and appear to be determined through protein-protein interactions between the viral integrase and cellular proteins.Two cellular proteins have been proposed to perform integration targeting roles, the chromatin-remodeling factor integrase interactor 1 (INI1/hSNF5/BAF47) and the lens epithelium-derived growth factor/transcriptional co-activator (LEDGF). Here, we report the initiation of two novel integration assays to study the contribution of INI1 and LEDGF in target site selection. Elucidating these molecular determinants and their functional implications is also of particular interest to anti-HIV therapy and could have major impact on the safety of gene therapy protocols.

The lack of foreign credential recognition by Canadian employers and professional associations is often cited as one of the explanations for the increasing earnings gap between Canadian workers and immigrant workers. The main objective of my dissertation is to look at different aspects of economic integration of immigrants to Canada, and more specifically at issues related to credential recognition. The objective of the first analysis is to examine the extent to which, after arrival, immigrants find jobs in the same occupations in which they were employed in their home countries. I also examine the effect on earnings of a match between the pre- and post-immigration occupations. Our results suggest that most recent immigrants move into a new occupation when they arrive in Canada and that those whose pre- and post-immigration occupations match tend to earn more. In the second analysis, I determine how many immigrants work in regulated and unregulated occupations and look at how education is associated with the likelihood of working in a regulated occupation. In aggregate, immigrants are slightly less likely to work in a regulated occupation. Immigrants educated in Asia, Latin America, and the Caribbean prove to be much less likely to secure access to a regulated occupation than either the native-born or other immigrants. The objective of the third analysis is to understand the transition between immigrants' premigration education and their educational trajectories once in Canada, and the return on investment in postmigration education in terms of employment status and earnings. A third of new immigrants with postsecondary training pursue their education during their early years in Canada. Those who enrol do not see an immediate benefit in terms of their earnings and employment status. In the last chapter, I examine foreign credential recognition processes in Canada and recent public investments to address this issue. Gaining foreign credential recognition from aLe manque de reconnaissance des titres de compétences acquis à l'étranger est l'une des causes souvent citées pour expliquer l'augmentation de la disparité salariale entre immigrants et non-immigrants au Canada. Le principal objectif de ma thèse est d'examiner différents aspects de l'intégration économique des immigrants au Canada, et plus particulièrement ceux liés à la reconnaissance des titres de compétences étrangers. Le but de la première étude est d'analyser le lien entre le domaine de l'emploi principal occupé par les immigrants avant leur arrivée et les emplois qu'ils ont occupés en début d'établissement, ainsi que l'effet net d'une adéquation des emplois sur le revenu des immigrants récents. Les résultats suggèrent que la plupart de ces immigrants ne se trouvent pas un emploi dans leur domaine; par ailleurs, ceux qui y parviennent ont un salaire plus élevé. Dans la deuxième analyse, je détermine combien d'immigrants travaillent dans des professions réglementées et non réglementées. J'examine comment l'éducation est associée à la probabilité de travailler dans une profession réglementée et, dans l'ensemble, les immigrants sont un peu moins susceptibles de travailler dans de telles professions. Les immigrants formés en Asie, en Amérique latine et dans les Caraïbes ont beaucoup moins de chances d'occuper une profession réglementée que les autres immigrants et les non-immigrants. L'objectif de la troisième analyse est de comprendre la transition entre l'éducation pre-migratoire et les trajectoires d'éducation au Canada, et les effets de l'investissement en éducation post-migratoire sur l'employabilité et le revenu. Un tiers des nouveaux immigrants ayant une formation postsecondaire poursuivent leurs études pendant leurs premières années au Canada. Ceux qui s'inscrivent à un programme de formation ne voient pas un bénéfice immédiat sur leur revenu et les chances d'être en emploi. Dans le dernier chap

Prometheus aims to explore artificial intelligence in a controlled but flexible environment by mimicking the properties of the real world using a swarm intelligence implementation. Swarm Intelligence has been used for solving problems in the domain of self organization, complexity and collective intelligence for a group of agents. The collective behavior of the entity considered here - ants, are modeled as a decentralized and self-organized system in which the ants communicate indirectly and thrive by modifying the environment. This novel approach combines the widely established stigmergy theory with real-time fluid dynamics by using Pheromones and the Navier-Stokes equations respectively to subject the environment to natural conditions like wind, and spread and decay of smell thus making the environment more suitable to real time conditions. The chosen real-time fluid dynamics method proves to be computationally fast, robust and far more realistic than traditional approaches. Also, for evaporation, instead of choosing a random fixed value for every timestep, we take into consideration the effect of temperature, vapor pressure, wind and humidity on evaporation and consequences of that. It is hoped that this model will be a step closer to achieving results substantially closer to the real world and also, observing the changes that the aforementioned natural properties might impose on the experimental world.Le projet d'intelligence artificielle Prometheus vise à explorer, dans un environnement contrôlé mais flexible, les propriétés du monde réel sur une intelligence en essaim. L'intelligence distribuée a été utilisée afin de résoudre les problèmes dans le domaine de l'auto-organisation, la complexité et l'intelligence collective d'un groupe d'agents. Le comportement collectif de l'entité considérée, ici la fourmi, est modélisé comme un système décentralisé et auto-organisé dans lequel les fourmis communiquent indirectement et prospèrent en modifiant l'environnement. Celle nouvelle approche combine la théorie de stigmergie avec la mécanique des fluides, utilisant respectivement les phéromones et les équations de Navier-Stokes, afin de soumettre à l'environnement des conditions naturelles comme le vent ou encore la propagation et la désintégration de l'odeur. Ainsi l'environnement correspond mieux à des conditions réelles. La méthode de mécanique des fluides en temps réel choisie, s'avère être rapidement calculable, robuste et beaucoup plus réaliste que les approches traditionnelles. De plus, pour modéliser l'évaporation, au lieu de choisir une valeur aléatoire fixée pour chaque itération, nous prenons en compte l'effet de la température, de la pression de la vapeur, du vent, de l'humidité de l'évaporation et leurs conséquences. Nous pensons que ce modèle contribuera à l'obtention de résultats nettement plus proches du monde réel et à l'observation des changements que les propriétés naturelles susmentionnées pourraient imposer à l'environnement expérimental.

This study investigated friendship formations of two girls with Down Syndrome who were integrated into a unit of 34 ten and eleven-year-old girls at a residential summer camp. While acting as participant observer, in the role of co-counsellor, I recorded behavioural observations and informal interviews in a journal, friendship log and personal log. A quantitative data analysis investigated the frequency with which campers elected to be with these two girls, as well as the number of campers who chose them as their best friends, as preferred bunkmates for next year and as those with whom they would want to keep in touch. A qualitative data analysis investigated the comments made by campers and counsellors concerning the program and the two girls of interest to this study. Results indicated that these two girls formed friendships during this month-long program. Limitations of this investigation are considered and some suggestions for further research are explored.

A comparison of heart rate viability and respiratory sinus arrhythmia (RSA) characteristics was performed in 20 athletes and 12 age-matched sedentary controls (CTRL) (22 +/- 2.4 yrs). More specifically, this study examined the role of regular physical activity on the breathing frequency (BF)---RSA amplitude response curve comparing varsity swimmers (SW) to endurance runners (RU) to test the hypothesis that a locomotor-respiratory entrainment resulting from the water-immersion breathing pattern of swimmers would alter their respiratory related cardiac vagal integrative response. Spectral power components of HRV were computed from R-R interval sequences. Five-minute recordings were performed with subjects breathing either at their spontaneous breathing rate, at four breathing cycles less (M4) and four cycles more (P4) than spontaneous. Amplitude and phase of RSA were computed from the sinusoid fitted to the instantaneous heart rate within each breath while the gain of the RSA response was obtained from the slope of the RSA amplitude versus BF.

Response to antipsychotic (AP) medication is critical to predicting long-term outcome in schizophrenia. This study examined the relationship between treatment response (TR) and four risk factors for schizophrenia. Method. Twenty-six outpatients were interviewed to assess childhood trauma and substance use. Patients' mothers completed interviews concerning family history of schizophrenia spectrum disorders and obstetric complications. TR was evaluated through information gleaned from medical records. Results. Family history of schizophrenia spectrum disorders (FH) was associated with decreased response to typical APs (r = -.37, p < .05). More severe childhood trauma was associated with worse TR (r = -.51, p < .001) while premorbid LSD use was associated with better TR (r = .52, p < .01). Further examination revealed that FH moderated the effects of trauma and LSD use on response to typical APs. None of the putative risk factors explained variance in TR to atypical APs. Conclusion. Childhood trauma and premorbid LSD use may cause permanent neurochemical changes responsible for altered TR in some individuals.

In this thesis, the author investigates the link between the process of economic and political integration within the European Union and the phenomenon of nationalist assertion. By examining the cases of Flanders and Scotland, it is argued that increased nationalism is a normal and predictable outcome of the process of integration in general, and of the EU more specifically. By analysing four factors--economic incorporation, system-wide policies, systems of transfer payments, and political isolation--the author finds two trends within the nationalist movements. The first is that the nationalist groups seek to acquire several of the powers currently held by the states of which they are currently part, Belgium and the United Kingdom respectively. The second is that these sub-state groups see themselves as part of a new order in which states are losing their significance. Neither of the theories associated with these observations on their own, however, satisfactorily explains the link between integration and increased nationalist assertion in the nationalist movements studied. The conclusion is that the nationalist groups accept the concept of an authority above the level of the state, nation, or region, but emphasise the necessity of a large degree of regional autonomy and a real voice for these regions in the decision-making process of this authority. Since the European Union is and always has been an exclusive club of member states, nationalist groups consider, within the framework of current institutional arrangements, that full statehood may be the only way to achieve their goals.

Coupled waveguides, such as directional couplers and grating-assisted directional couplers, have many applications in integrated optics, optical communication and nonlinear optics. In this thesis, we investigate two important applications of them in optical integration and nonlinear frequency conversion. The work presented in this thesis is composed of two main parts. In the first part, we present a compact double-grating coupler between silicon-on-insulator (SOI) waveguides. This type of waveguide coupler has potential applications in multi-layer photonic integrated circuits. In the second part, we investigate nonlinear frequency conversion, such as second harmonic generation, in directional couplers.The double-grating coupler consists of two gratings: one acting as an outcoupler to couple the guided light from a waveguide to its radiation mode, and the other acting as an incoupler to couple the light in the radiation mode to the guided mode of another waveguide. The coupling between these two waveguides is therefore achieved. Since the coupling does not require field overlap between the guided modes of the two waveguides, the separation between the two waveguides can be large. This advantage leads to promising applications in optical integration in multi-layer photonic integrated circuits. A transfer efficiency of 29% is achieved between two SOI waveguides, and further optimization is possible by using blazed-gratings and Bragg reflectors.
In the second part of this thesis, we investigate a new theory for nonlinear frequency conversion in directional couplers. As is well known, when a harmonic oscillator is driven at resonance by an external harmonic force, the largest possible oscillation amplitude is obtained. Coupled mode theory shows that similar phenomena occur when the nonlinear effect takes place in a waveguide directional coupler. We show that by considering the amplitude of the second harmonic signal in the coupled waveguides as an oscillator and the nonlinear polarization as an external harmonic force, a resonant condition can be found, resulting in highly efficient power transfer from pump to signal. Similar resonant effects also occur in other nonlinear frequency conversion effects. The proposed phenomena can also be understood by phase-matching between the supermodes of directional couplers. On one hand, the new theory has fundamental significance for nonlinear optics, on the other hand, it also demonstrates that waveguide directional couplers can be found in a new application area besides integrated optics and optical communication. We also report the first experimental observation of continuous-wave second-harmonic generation in waveguide directional couplers. We employ a GaAs/AlGaAs system and observe four resonance peaks in a ∼15nm spectral range, with a maximal conversion efficiency of 1.6%W-1cm-2. This new configuration has the potential to open a new range of applications for nonlinear frequency conversion.

This thesis studies the process of extracting business value from Enterprise Resource Planning (ERP) through integration. The main premise is that performance differences across firms investing in similar ERP systems can be attributed to differences in the way the technology (ERP) is integrated with the actual IT infrastructure and business processes of the firm. Drawing on the entrepreneurship and integration literature, this thesis focuses on the antecedents of integration and its impact on business process performance. To better understand this phenomenon, this thesis adopts a multi-method and multi-essay approach. The first essay looks at how different degrees of integration are achieved by looking at the effect of managers' alertness and search activity on integration. It also demonstrates the influence of perceived gap as a trigger of search. The second essay develops and proposes a measure of integration in an ERP context at the module level. Finally, the last essay applies the notion of integration to better understand its effect on business process performance by looking at its antecedents and how different degrees of integration influence the performance of the business processes. All essays are empirical; case studies for the first one and survey for the last two essays. These essays can be seen as components of an integrative investigation of the issue of ERP value creation through integration, which is likely to help us understand how and under which circumstances ERP systems can produce value for the firms implementing them.La présente thèse étudie le processus d'extraction de valeur des systèmes de gestion intégrée (ERP). La prémisse principale de cette thèse est que la différence de performance entre les organisations qui investissent dans des systèmes ERP similaires puisse être attribuée à la façon dont le système est intégré avec l'infrastructure technologique actuelle et les processus d'affaires de l'organisation. Basé sur la littérature en entrepreneuriat et en intégration, cette thèse fait le point sur les antécédents et les impacts de l'intégration d'un module ERP. Pour mieux comprendre ce phénomène, cette thèse adopte une approche multi-méthode repartie sur trois articles. Le premier article examine comment l'intégration est accomplie à travers le niveau d'alerte et de recherche des gestionnaires, ce dernier dépendant du gap perçu entre le système et les processus d'affaires actuels. Le deuxième article développe et propose une mesure d'intégration dans un contexte ERP au niveau du module. Finalement, le dernier article applique la notion d'intégration pour mieux comprendre ses antécédents et son effet sur la performance des processus d'affaires. Tous les articles sont empiriques : études de cas pour le premier et enquête pour les deux autres articles. Ces articles peuvent être vus comme les composantes formant une vision complémentaire de l'investigation de la création de valeur des systèmes de gestion intégrée à travers le processus d'intégration.

This study was designed to examine the ability to use prior knowledge in text comprehension and knowledge integration. The focus of the research was on effects of different degrees of subjects' theoretical knowledge in the domain of biochemistry on their comprehension of written technical materials describing experimental procedures and results, and the ability to integrate such new text derived information with prior theoretical knowledge considered by experts to be relevant to the topic. Effects of cues on the accessibility and use of prior knowledge were also examined. Pre-test questions testing the extent of subjects' prior knowledge of photosynthesis, and a "cue article" specifically designed to prime subjects' relevant prior knowledge of photosynthesis, served as cues in the study.A theoretical model of experts' knowledge was developed from a semantic analysis of expert-produced texts. This "expert model" was used to evaluate the extent of students' theoretical knowledge of photosynthesis, and its accessibility while applying it to the experimental tasks. College students and university graduate students served as subjects in the study, permitting a contrast of groups varying in prior knowledge of and expertise in chemistry.
Statistical analyses of data obtained from coding subjects' verbal protocols against text propositions and the expert model revealed that prior knowledge and comprehension contribute significantly to predicting knowledge integration, but they are not sufficient for this process to take place. It appears that qualitative aspects and specific characteristics of subjects' knowledge structure contribute to the process of integration, not simply the amount of accumulated knowledge. There was also evidence that there are specific inferential processes unique to knowledge integration that differentiate it from test comprehension. Cues manifested their effects on performance on comprehension tasks and integrative tasks only through their interactions with other factors. Furthermore, it was found that textual complexity placed specific constraints on students' performance: the application of textual information to the integrative tasks and students' ability to build conceptual frame representations based on text propositions depended on the complexity of the textual material.

The generation of electricity using wind turbines is now widespread and commercially viable. There are two aspects of wind energy which are critically important. Firstly, the evaluation of the wind resource, both on nationally and on a local scale. Secondly, the integration of electricity generated by wind turbines into existing electricity grids without reducing the reliability of supply or reducing the overall economic efficiency of the system. This thesis examines both these aspects. Chapters 3 and 4 are concerned with the large scale utilisation of wind energy. Chapter 3 discusses the suitability for wind energy evaluation of the data held by the UK Meteorological office, describes the results of a detailed examination of over 130 station-years of hourly data, and recommends areas of further study as well as a UK standard for site description. Chapter 4 describes a computer model used to examine the effects of integrating wind-generated electricity into the CEGB National Grid and the results obtained with it. The relative importance of dispersal of wind turbines, load and wind forecasting, variation of turbine characteristics and inter-annual variability of wind speed is determined. Chapters 5 and 6 are concerned with a detailed evaluation of thewind energy potential on the Shetland island group. Chapter 5 describes the planning, testing and installation of two hill-top monitoring stations on Shetland and the results found. Chapter 6 describes the development of a computer model of the Shetland Power Station, which is used to examine how the introduction of wind turbines would affect the operation of the power station and the maximum energy penetration possible before power cuts occur. Both chapters conclude with detailed recommendations which will be of worldwide use as the wind energy potential of other diesel-fuelled grids is determined.

The way in which distribution networks are operated and managed from the control room is changing as a result of a number of external factors, most prominently the mounting interest in renewable generation technologies and growing trends of connecting small scale generation plants at distribution level voltages in decentralised locations. Growing interest in distributed generation (DG) presents a challenge to the validity of existing distribution control room procedures and supporting tools. To accommodate large penetrations of DG, a more active approach to control is necessary and extensive research and development is currently underway in this area. Active network management (ANM) is one of the enabling strategies that will allow DG to connect, whilst potentially postponing the need for costly and time consuming network reinforcements and upgrades, by operating the network closer to its limits through real-time monitoring and control of system parameters. Parameters such as power flow and voltage, and embedded resources such as responsive demand and DG can all be controlled in a more active manner such that network resources can be used more efficiently. The management of future active distribution networks is a concern as such changes will impact the control room in various ways. This thesis describes the changes that will occur on networks and how they will affect the control room in different ways, as well as the uncertainties associated with DG and ANM deployment. A Control Room Demonstration Suite (CoRDS) provides a comprehensive view of future networks and their operational issues, allowing preparatory measures to be taken by Distribution Network Operators (DNO). The CoRDS is also used to study the required behavioural changes of distribution control engineers in the way they will interact with ANM schemes.

Future high performance digital computing systems will demand extremely high throughput and connection-intensive backplanes. Free-space optical interconnects have the potential to meet these demands. This thesis explores the application of a two-dimensional array of metal-semiconductor-metal (MSM) photodetectors in a free-space photonic backplane. In particular, two-dimensional smart pixels are presented as a means of achieving a large communications space-bandwidth product. It is argued that a system based on such devices can overcome several physical limitations experienced by electrical interconnects of current printed circuit board based electronic backplanes. As a means to this end, a review of MSM photodetector technology is then conducted.The layout and design of the optical receiver is presented. The effects of misalignments, optical power variations, and device non-uniformity on receiver performance are considered. With these design parameters in mind, the construction of a receiver assembly is described from the first step of packaging the photodetector array to the last interconnecting cable connection. Specific packaging challenges that are discussed include power dissipation, connectivity, and electrical isolation as related to receiver performance. The method and results of characterization are presented in relation to its meeting the requirements of a receiver array in a free-space optical backplane. Future areas for improvement are then considered.

The increasing intermingling of civilian and military space activities could lead to serious, and perhaps unintended, consequences. While international space law is very permissive with regard to military uses of space, there are considerable legal and security implications resulting from military and civilian dependence on the same space services. From a military perspective, intentional reliance on civilian systems must address, inter alia, national security concerns, contractual obligations, licensing restrictions, liability, and long-term political relationships, while respecting the interests of the commercial sector. Policy decisions leading to an increase in civilian-military space interdependence must also consider potential impacts of this symbiosis on trade, international relations, and the conduct of armed hostilities. The thesis addresses these and certain related issues in four chapters. The first chapter explores the depth of the interdependence of military and civilian users on the same space systems. The second chapter considers the implications of dual use space technologies, such as proliferation concerns. The third chapter discusses various legal mechanisms States employ to address security issues involving space activities. The final chapter outlines legal restrictions on the use of space assets by armed forces.
