Nowadays, telecommunication services are commonly deployed in private networks, which are controlled and maintained by the telecommunication operators themselves, by co-location services providers, or, to some extent, by their hardware and software providers. However, with the present development of cloud computing resources, one might consider if these services could and should be implemented in the Cloud, thus taking advantage of cloud computing’s high availability, geographic distribution, and ease of usage. Additionally, this migration could reduce the telecommunication operators’ concerns in terms of hardware and network maintenance, leaving those to the Cloud computing providers who will need to supply a highly available and consistent service, to fulfill the telecommunication services’ requirements. Furthermore, virtualization provides the possibility of easily and rapidly changing the Cloud network topology facilitating the addition and removal of machines and services, allowing telecommunication services providers to adapt to their demands on the fly. The aim of this thesis project is to analyze and evaluate the level of performance, from the network point of view, that can be achieved when using Cloud computing resources to implement a telecommunication service, carrying out practical experiments both in laboratory and real environments. These measurements and analyses were conducted using an Ericsson prototype mobile switching center server (MSC-S) application, although the results obtained could be adapted to other applications with similar requirements. In order to potentially test this approach in a real environment, a prior providers’ survey was utilized to evaluate their services based on our requirements in terms of hardware and network characteristics, and thus select a suitable candidate environment for our purposes. One cloud provider was selected and its service was further evaluated based on the MSC-S application requirements. We report the results of our bench-marking process in this environment and compare them to the results of testing in a laboratory environment. The results of both sets of testing were well correlated and indicate potential for hosting telecommunication services in a Cloud environment, providing the Cloud meets the requirements imposed by the telecom services.Actualmente, los servicios de telecomunicaciones se implementan comúnmente en redes privadas, controladas y mantenidas por los operadores de telecomunicaciones, por proveedores de servicios de colocación o, hasta cierto punto, por proveedores de hardware y software. Sin embargo, con el presente desarrollo de la tecnología de ’Cloud computing’, se puede considerar la posibilidad de implementar servicios de telecomunicaciones en la nube, aprovechando su alta disponibilidad, distribución geográfica y facilidad de uso. Además, este cambio puede reducir las preocupaciones de los operadores en relación al mantenimiento del hardware y de la red, delegando en los proveedores del servicio de ’Cloud computing’, los cuáles deberán proporcionar un servicio consistente, cumpliendo así con los requisitos de los servicios de telecomunicaciones. Por otra parte, la virtualización propociona la posibilidad de cambiar rápida y fácilmente la topología de la red, facilitando la adición y supresión de maquinas y servicios, y, por tanto, permitiendo a los operadores adaptarse a sus necesidades sobre la marcha. El objetivo de esta tésis es analizar y evaluar en nivel de rendimiento, desde el punto de vista de la red, que se puede conseguir usando recursos de ’Cloud computing’ para implementar un servicio de telecomunicaciones, llevando a cabo experimentos tanto en el laboratorio como en un entorno real. Estos análisis fueron realizados utilizando un prototipo de un servidor de conmutación móvil (MSC-S) de Ericsson, aunque los resultados pueden adaptarse a otras aplicaciones con unos requisitos similares. Para probar esta propuesta en un entorno real, se realizó una encuesta de proveedores de servicios de ’Cloud computing’, con el objetivo de evaluar sus servicios teniendo en cuenta nuestros requisitos de hardware y red. Finalmente, un proveedor fue escogido y su servicio evaluado basándonos en los requisitos de la aplicación MSC-S. En este documento proporcionamos los resultados de esa evaluación y los comparamos con los obtenidos en el laboratorio. Los resultados de ambas evaluaciones fueron satisfactorios e indican la posibilidad de implementar servicios de telecomunicaciones en la nube, siempre que la nube cumpla los requisitos impuestos por dichos servicios de telecomunicaciones.
Nuförtiden är telekommunikationstjänster ofta uppsatta i privata nätverk, som kontrolleras och underhålls av teleoperatörerna själva, av samlokaliserande tjänsteleverantörer eller i viss utsträckning av deras hårdvaruoch programvaru-leverantörer. Med den nuvarande utvecklingen av Cloud Computing-resurser kan man dock överväga om dessa tjänster kan och bör genomföras i ett Cloud, vilket drar fördel av Cloud Computings höga tillgänglighet, geografiska spridning, och enkla användning. Denna migration minskar även teleoperatörernas oro angående hårdvaru- och nätverks-underhåll genom att överlåta detta till Cloud Computing-leverantörerna, som kommer att behöva leverera en hög tillgänglighet och konsekvent service för att uppfylla telekommunikationstjänsternas krav. Dessutom ger virtualisering möjlighet att enkelt och snabbt ändra ett Clouds nätverkstopologi, vilket underlättar tillägg och borttagning av maskiner och tjänster, vilket hjälper teleoperatörer att snabbt anpassa sig till deras krav. Målet med examensarbetet är att analysera och uppskatta prestandan, från nätets perspektiv, som kan uppnås vid användning av Cloud Computingresurser för att genomföra en teletjänst, genom praktiska experiment både i laboratorium och i verkligheten. Dessa mätningar och analyser utfördes med en prototyp av en Ericsson mobilomkopplingscentralserverapplikation (MSCS), även om de erhållna resultaten skulle kunna anpassas till andra program med liknande krav. För att potentiellt kunna testa denna metod i en verklig miljö användes en tidigare leverantörs undersökning för att utvärdera deras tjänster baserat på våra krav på hårdvara och nätverksegenskaper, och genom detta välja en lämplig kandidatmiljö för våra syften. En Cloud-leverantör valdes och dess tjänster utvärderades vidare baserat på MSC-Ss applikationskrav. Vi redovisar resultatet av vår testprocess i den här miljön och jämför det med resultaten av tester i laboratoriemiljö. Resultaten från båda uppsättningarna av tester var väl korrelerade och visar på potentialen av att implementera telekommunikationstjänster i en Cloud-miljö, om detta Cloud uppfyller de kraven som ställs av telekommunikationtjänsterna.

Depuis quelques générations, la libéralisation des échanges et des marchés facilite considérablement les mouvements transfrontaliers de biens, de services, de capitaux et d’informations. Ce processus d’intégration est porteur de gains de bien-être inédits pour la population mondiale. Des perspectives importantes s’ouvrent aussi pour les pays en développement, dont la croissance pourrait tirer de nouvelles stimulations de la mise en œuvre de réformes favorables aux échanges et à l’ouverture des marchés. Mais un pan de l’édifice de la mondialisation est demeuré en grande partie étranger à ce processus de libéralisation : les mouvements de capital humain, qui restent soumis à un contrôle et à des restrictions sévères. Il y a lieu de le déplorer, car la libéralisation des migrations temporaires de main-d’œuvre pourrait constituer un moteur de croissance économique et de développement plus efficace que tout autre levier d’action politique. Nombre de pays en développement sont doués d’un important capital humain. C’est un facteur de production et un mode de prestation de services où ils sont nombreux à jouir d’un avantage comparatif. Nous avons circonscrit notre champ d’étude à la migration temporaire de main-d’œuvre qualifiée des pays pauvres vers les pays riches. Notre exposé est axé sur trois études de cas poussées, celui de pays figurant parmi les principaux exportateurs de main-d’œuvre au monde – l’Égypte, l’Inde et les Philippines – dont nous examinons quelques-unes des activités de services les plus saillantes, à savoir respectivement : l’éducation, la santé et les technologies de l’informationMore than half a century of trade and market liberalisation have greatly facilitated the movement of goods, services, capital and information across borders. This integration process has brought unprecedented welfare gains to the wor1d's population and there is much scope to stimulate further economic growth in developing countries through market and trade friendly reforms. One piece in the globalisation puzzle has largely been excluded from the liberalisation process: the movement of human capital remains highly controlled and restricted. This is regrettable since the liberalisation of temporary labour movement could have a greater impact on economic growth and development than any other single policy. Many developing countries are well endowed with human capital and it is a factor of production and a mode of service delivery in which many developing countries enjoy a comparative advantage. This dissertation focuses on temporary migration of skilled workers from poor to rich countries. The underlying assumption-based on economic models and empirical findings-is that a more liberal environment for temporary labour mobility would bring substantial welfare gains by stimulating economic growth and development. Consequently, the focal point is on trade rather than immigration (or so called 'brain circulation' rather than 'brain drain'). The dissertation is centred on three in-depth studies of some of the world's leading labour sending countries: Egypt, India and the Philippines; and some of their most prominent services sectors: education, IT, and health services

Анотація:
Over the last forty years, we have witnessed the birth of a new phenomenon in the Western world, that of 'the dream retirement. ' This study examines a group of (mainly) Northern European older people who move to Spain in search of the culmination of their life-project. Following years of working to the clock they move away from the 'rat-race' to find warmth, good health, company, friendship and enjoyment. Yet [...] the experience is often judged negatively by outsiders. The Costa is portrayed as a slightly unreal world, a liminal zone beyond the 'normal' realm of work. This thesis, an ethnographic exploration of life for older migrants in Spain takes seriously this 'unreal' world. It explores the negotiation of the designated 'free-time' at the end of the working life. The creation of retirement at a determined legal cut-off point has forced a separation between working identities and identities in the life beyond, which previously had (if at all) a ragged boundary between them. In short, it is a modern-day rite of passage. Now, as retirement approaches, new questions come to the fore. Where should we retire? How do we negotiate that culturally created 'time off' at the end of the working years? Do we find satisfaction, companionship, hope and fulfilment of dreams? Perhaps more mundanely,what do we actually do with that time? This thesis is an ethnographic study devoted to exploring the lives and worlds of older people who, in answering the above questions, chose to migrate to Spain from Northern Europe. Its focus is the new brand of 'woopies' (well off older persons) seeking the 'rewards' of leisure following a lifetime of working. They enter an interstitial space devoted to the pursuit of adult play. The thesis interrogates the reality of such rewards, looking at the tensions inherent in the 'freedom' sought within utopian spaces such as Spain. I reveal how the imagined freedoms necessitate some form of regulation, and I employ a re-examination of anthropological models of ritual to do so.

Chapter 1 Low-skilled Migration and Altruism: Population ageing has become a common concern among welfare states, including Canada and most of the OECD countries. Immigration has been identified as a solution to help sustain labour-force growth in industrialized countries, and as the factor most able to mitigate dire predictions of future fiscal imbalances. This chapter examines the impact of low-skilled immigration in a host country where households are altruists with a pay-as-you-go pension system to support the elderly. It demonstrates that low-skilled immigration does not harm the welfare of the domestic population. We use an overlapping-generations model similar to the work of Razin and Sadka (2000) but introduce paternalistic altruism into the life-cycle framework. Within this context of inter-generational altruism and pay-as-you-go pension systems, the initial negative fiscal impact of low-skilled migrants is compensated, thus, all income groups (high and low) and all age groups (young and old) benefit from migration. // Chapter 2 Growth and Sustainability: In light of the major environmental issues experienced by several countries in the last decades, several papers have advocated the rethinking of the role of governments in environmental preservation. This chapter develops an overlapping-generations model of environmental quality and production and investigates the potential role of governmental participation in the preservation of the quality of the environment so as to achieve both economic growth and environmental sustainability. The analysis suggests that long term economic growth and environment sustainability can be maintained with tax-funded environmental programs in a context of a negative production externality on the quality of the environment. // Chapter 3 The Incidence of Geography on Canada’s Services Trade: We estimate geographic barriers to export trade in nine service categories for Canada's provinces from 1997 to 2007 using the structural gravity model. Constructed Home, Domestic and Foreign Bias indexes capture the direct plus indirect effect of services trade costs on intra-provincial, inter-provincial and international trade relative to their frictionless benchmarks. Barriers to services international trade are huge relative to inter-provincial trade and large relative to goods international trade. A novel test confirms the fit of structural gravity with services trade data.

Les avancées des techniques de virtualisation et la maturité des langages d'orchestration ont contribué à la conception et au déploiement de services cloud composites. Ces services cloud peuvent être sujets à des changements dans le temps, en raison de la migration de leurs ressources. Cela peut introduire de nouvelles vulnérabilités, qui compromettent un service cloud dans son ensemble. Dans ce contexte, cette thèse propose d'améliorer et d'automatiser la sécurité des services cloud composites selon trois axes principaux. Le premier axe consiste en un framework de sécurité automatique basé sur SMT pour prendre en charge les migrations dans les services cloud composites, comme ceux orchestrés avec le langage TOSCA (Topology and Orchestration Specification for Cloud Applications). Il s'appuie sur des techniques de vérification pour évaluer automatiquement les changements de configuration qui affectent les composants des services cloud pendant leurs migrations, déterminer les vulnérabilités potentielles et sélectionner des contre-mesures adéquates. Le deuxième axe étudie la conception d'un tiers de confiance inter-cloud, appelé C3S-TTP (Composite Cloud Configuration Security-Trusted Third Party). Celui-ci est capable de réaliser une évaluation précise et exhaustive des vulnérabilités, tout en limitant les informations partagées entre le fournisseur cloud et le client cloud. Le troisième axe est centré sur l'investigation d'une stratégie défensive par cible mouvante qui combine des algorithmes d'intelligence artificielle avec des techniques de vérification. Le but est de compromettre les activités de reconnaissance effectuées par les attaquants à travers une large exploration des états, tout en minimisant l'apparition de nouvelles vulnérabilités qui peuvent avoir un impact important sur la surface d'attaques des services cloud concernésThe advances in virtualization techniques and the maturity of orchestration languages have contributed to the design and deployment of cloud composite services. These cloud services may be subject to changes over time, due to the migration of their resources. This may introduce new vulnerabilities, that compromise the whole services. In that context, this thesis proposes to enhance and automate the security of cloud composite services, according to three main axes. The first axis consists in an automated SMT-based security framework for supporting migrations in cloud composite services, such as those orchestrated with the TOSCA (Topology and Orchestration Specification for Cloud Applications) language. It relies on verification techniques for automatically assessing the configuration changes that affect the components of cloud services during their migrations and determining adequate countermeasures. The second axis investigates the design of an inter-cloud trusted third party, called C3S-TTP (Composite Cloud Configuration Security-Trusted Third Party). This one is capable to perform a precise and exhaustive vulnerability assessment, without requiring the cloud provider and the cloud tenant to share critical configuration information between each other. The third axis is centered on the investigation of a moving target defense strategy which combines artificial intelligence algorithms together with verification techniques. The purpose is to deceive reconnaissance activities performed by attackers through a large exploration of states, while minimizing the occurrence of new vulnerabilities that may impact on the attack surface of cloud composite services

The purpose of this thesis is to examine the relationship between expenditures on local public services and the net migration rate for Swedish urban and rural municipalities. Data from Statistics Sweden over all Swedish municipalities between 2004 and 2014 was used for the empirical analysis. The data also included control variables to control for differences in economic and demographic conditions in the municipalities. The result found using pooled OLS with instrumental variables reveals great differences on the significance of local service expenditure in relation to migration for the two types of municipalities. Childcare was found to be of great significance for rural regions. In contrast, social assistance had a positive association in urban regions while it had a negative insignificant correlation in rural regions. Moreover, culture and education were found to be insignificant in relation to migration for both regions. The results also showed similarities such as elderly care and local taxes were significantly negatively correlated with migration in both type of regions. Overall, the results show that certain local services, such as childcare, are correlated with migration. Nevertheless, economic conditions such as low local taxes, presence of a university campus and having low unemployment are as well of importance to attract residents to both types of municipalities.

Les choix de configuration d'un systeme reparti et cooperatif influencent directement le comportement du systeme, et a fortiori la qualite de ses performances. Par systeme reparti et cooperatif nous entendons un ensemble de services offerts aux developpeurs d'applications. Ces services sont localises sur differentes machines hotes (repartition), et peuvent interagir (cooperation). Observer les services afin d'agir sur leur repartition et leurs facultes cooperatives, contribue au bon fonctionnement de l'ensemble du systeme. Nous considerons un service comme une entite constituee d'interface(s), de porte(s) d'acces, et d'un comportement. Les interfaces fournissent les moyens d'acceder au service, les portes d'acces collectent les requetes des clients, et le comportement traduit les traitements specifiques realises par le service. Notre problematique est celle de la gestion dynamique de configuration ; elle concerne en particulier la migration de service et de l'ajustement (ou tuning) de portes d'acces. Migrer un service signifie modifier sa localisation dans l'environnement ; ajuster ses portes d'acces traduit le fait d'augmenter ou de reduire le nombre de ses portes. Le caractere dynamique des solutions proposees, apporte la transparence necessaire au maintien des liens de cooperation existant, et a la minimisation des risques de dysfonctionnement dans le systeme. Une troisieme dimension complete celles de migration et d'ajustement: la mesure d'activite. Son objectif est de recuperer periodiquement sur les services geres, des metriques de charge (en nombre de clients) et de temps de reponse, afin de doter le niveau decisionnel d'informations dont l'interpretation concourt a la prise de decisions d'operations de migration ou d'ajustement. Les mecanismes de gestion definis s'integrent au sein d'une entite federatrice appelee micro-manager ; cette integration favorise a la fois la mise en uvre des mecanismes, et leur utilisation par des applications de gestion

This thesis investigates migration aspirations and experiences of female Polish migrant workers and returnees, who have been working and living in the UK. In the face of theoretical debates and a lack of knowledge on the experience of Polish women as migrant workers in the UK, a contextualised study prioritising the narratives of the interviewees was established. The theoretical and methodological approach is characterised by grounded theory methodology informed by theoretical sensitivity, which is combined with the analysis of biographical narrative interviews, semi-structured expert interviews, and secondary quantitative data. Through this approach, the conditions and influential factors that shape female Polish migrant workers’ aspirations and experiences, as well the way in which they make meaning of them, are scrutinised. Different patterns of migration aspirations have been constructed by the informants’ narratives – migration as a solution, as a family strategy or as an opportunity. Furthermore, specificities of working and living in the UK have been established, marked by different routes into employment, migrant and feminised work, and different patterns of work trajectories; as well as social networks, transnational lives and experiences of women and family life. Constructions of return decisions or the lack of return motivations, as well as experiences after return, bring forth the relevance of expectations resulting in the question: ‘return to what?’ Additionally, return plans have been adapted in the face of structural constraints or because of individual preferences, which were at times overruled in the context of return as a family strategy. Return was also constructed, however, as path to personal or professional fulfilment, as an opportunity, or as a result of disappointment. In the context of the conditions of the enlarged EU providing the freedom of movement, the post-transformation labour market in Poland, and the gendered and migrant labour market segmentation in the UK, as well as gender regimes, female Polish migrant workers actively mediated their migration aspirations and experiences.

In 1997, the Virginia Refugee Health Program coordinated a protocol and reimbursement structure to encourage health departments to perform initial health screenings on refugees settling in the Commonwealth by establishing four recommended levels of assessment. This thesis is concerned with these initial health-related services provided to refugees by Virginia's health departments, the quality of these services, and how they vary from one district to another. For this study, I interviewed health department staff representing 13 of Virginia's 19 districts that rendered health screenings in 2000. Information such as the level of assessment provided, and the types of procedures and services offered were the main foci of the interviews. I found that of the 13 districts, three (the cities of Alexandria and Virginia Beach, and Prince William County) offer only the required minimum to refugees. The variations I discovered in the services that health districts provide suggest, conceptually, the workings of both "structure" and "agency." Each health department is formally and informally structured in terms of staffing, services, and resources in accordance with its individual needs and initiatives. The structure of current funding at both the state and local level acts to inhibit some health districts from providing all four levels of assessment. In addition, human agency in the form of personal interest in meeting refugee's health needs as well as district collaboration with local resettlement agencies, also plays an important role in the extent of refugee services rendered.Master of Science

Анотація:
Migration is often conceptualised as a failure to adapt to environmental risks and change, while new research suggests migration is an effective front-line response to environmental degradation. This thesis investigates the social and environmental mechanisms that lead to individuals adopting migration as an adaptation to environmental change. It argues that the use of migration as a response to environmental change depends on the ecosystem services available at location, the mobility characteristics of the individual and the degree to which ecosystem contribute to place utility. I interpret place utility as a function of both instrumental and affective bonds to place. The research tests these ideas in a highland migrant sending area in a small coastal valley of Peru, geographically and culturally connected to the capital city Lima but predominantly rural in nature. The area has established rural-urban migration networks and a complex social-ecological system vulnerable to climate change. Data on mobility characteristics, contributors to place utility and use of ecosystem services in the rural sending area were collected through household surveys and semi-structured interviews. Four settlements were sampled along an altitudinal transect representing different ecological zones as well as different access to off-farm employment and other opportunities. Analysis of the primary data shows that individuals gain utility from non-provisioning ecosystem services independently of reliance on provisioning ecosystem services. These impacts of climate change that previously only had a cultural significance take on significance in terms of migration. The data show that individuals remain in location because of positive place utility or low mobility potential. I conclude that a likely result of environmental change is an increase in dissatisfaction with no significant changes in the composition of the population. Low mobility potential, a function of affective bonds to place, prevents dissatisfied people from migrating. The thesis shows that populations are likely to be persistent in the face of environmental change. Understanding why individuals remain in location reveals the viability of migration as an adaptation to environmental change.

The reproductive health problems of migrant women are a growing concern, especially in developing countries. The empirical literature indicates that migration characteristics (e.g., selection, adaptation and disruption) and migrant’s socio-demographic backgrounds are the potential pathway through which migration can affect reproductive health care services utilization. This study aimed to examine the effect of migration on women’s reproductive health care service utilization and to identify the major barriers that affect migrant women’s access to quality reproductive health care services. The study aim and objectives were achieved using two studies. Study one comprises a secondary analysis of the 2005 Ethiopian Demographic and Health Survey (EDHS). The EDHS was administered to women aged 15-49 years and a total of 14,070 women were interviewed and study two was a primary survey conducted in Dabat rural areas and Gondar town. A total of 1800 women were interviewed: 500 women from Dabat rural areas and 1300 women from Gondar town. Both surveys were employed a cross-sectional survey design. The two studies found that rural to urban migrants were relatively lower in knowledge and use of reproductive health care services compared to urban natives, but more likely to know and use of services than rural natives. The primary study also found that among migrant women, those who registered as kebele residents were more likely to know of, or utilize contraceptives and maternal health care services compared with non-registered migrants. To ensure the reproductive health care access of migrants, the urban kebele administrative offices should revise the policies that demand migrants to be registered as a kebele residents and having a kebele identification card to be eligible for social, economic and health care benefits. Therefore, the policy makers should target the disadvantaged groups of migrants to provide equal opportunities to access health care services.

Diese 'Grid Ressourcen' stehen jedoch nicht als kontinuierlicher Strom zur Verfügung, sondern sind über verschiedene Maschinentypen, Plattformen und Betriebssysteme verteilt, die jeweils durch Netzwerke mit fluktuierender Bandbreite verbunden sind. Es wird für Wissenschaftler zunehmend schwieriger, die verfügbaren Ressourcen für ihre Anwendungen zu nutzen. Wir glauben, dass intelligente, selbstbestimmende Applikationen in der Lage sein sollten, ihre Ressourcen in einer dynamischen und heterogenen Umgebung selbst zu wählen: Migrierende Applikationen suchen eine neue Ressource, wenn die alte aufgebraucht ist. 'Spawning'-Anwendungen lassen Algorithmen auf externen Maschinen laufen, um die Hauptanwendung zu beschleunigen. Applikationen werden neu gestartet, sobald ein Absturz endeckt wird. Alle diese Verfahren können ohne menschliche Interaktion erfolgen.
Eine verteilte Rechenumgebung besitzt eine natürliche Unverlässlichkeit. Jede Applikation, die mit einer solchen Umgebung interagiert, muss auf die gestörten Komponenten reagieren können: schlechte Netzwerkverbindung, abstürzende Maschinen, fehlerhafte Software. Wir konstruieren eine verlässliche Serviceinfrastruktur, indem wir der Serviceumgebung eine 'Peer-to-Peer'-Topology aufprägen. Diese “Grid Peer Service” Infrastruktur beinhaltet Services wie Migration und Spawning, als auch Services zum Starten von Applikationen, zur Dateiübertragung und Auswahl von Rechenressourcen. Sie benutzt existierende Gridtechnologie wo immer möglich, um ihre Aufgabe durchzuführen. Ein Applikations-Information- Server arbeitet als generische Registratur für alle Teilnehmer in der Serviceumgebung.
Die Serviceumgebung, die wir entwickelt haben, erlaubt es Applikationen z.B. eine Relokationsanfrage an einen Migrationsserver zu stellen. Der Server sucht einen neuen Computer, basierend auf den übermittelten Ressourcen-Anforderungen. Er transferiert den Statusfile des Applikation zu der neuen Maschine und startet die Applikation neu. Obwohl das umgebende Ressourcensubstrat nicht kontinuierlich ist, können wir kontinuierliche Berechnungen auf Grids ausführen, indem wir die Applikation migrieren. Wir zeigen mit realistischen Beispielen, wie sich z.B. ein traditionelles Genom-Analyse-Programm leicht modifizieren lässt, um selbstbestimmte Migrationen in dieser Serviceumgebung durchzuführen.
In recent years, there has been a dramatic increase in available compute capacities. However, these “Grid resources” are rarely accessible in a continuous stream, but rather appear scattered across various machine types, platforms and operating systems, which are coupled by networks of fluctuating bandwidth. It becomes increasingly difficult for scientists to exploit available resources for their applications. We believe that intelligent, self-governing applications should be able to select resources in a dynamic and heterogeneous environment: Migrating applications determine a resource when old capacities are used up. Spawning simulations launch algorithms on external machines to speed up the main execution. Applications are restarted as soon as a failure is detected. All these actions can be taken without human interaction.
A distributed compute environment possesses an intrinsic unreliability. Any application that interacts with such an environment must be able to cope with its failing components: deteriorating networks, crashing machines, failing software. We construct a reliable service infrastructure by endowing a service environment with a peer-to-peer topology. This “Grid Peer Services” infrastructure accommodates high-level services like migration and spawning, as well as fundamental services for application launching, file transfer and resource selection. It utilizes existing Grid technology wherever possible to accomplish its tasks. An Application Information Server acts as a generic information registry to all participants in a service environment.
The service environment that we developed, allows applications e.g. to send a relocation requests to a migration server. The server selects a new computer based on the transmitted resource requirements. It transfers the application's checkpoint and binary to the new host and resumes the simulation. Although the Grid's underlying resource substrate is not continuous, we achieve persistent computations on Grids by relocating the application. We show with our real-world examples that a traditional genome analysis program can be easily modified to perform self-determined migrations in this service environment.

High stability of telecommunication services has a positive e ect on customer satisfaction and thus helps to maintain competitiveness of the product in telecommunication market. Since live migration provides a minimal down- time of virtual machines, it is deployed by telecommunication companies to ensure high availability of services and to prevent service interruptions. The main objective of this research is to assess the performance of various hypervisors in terms of live migration and determine which of them best meets the criteria given by a telecommunication company. Response time and CPU utilization of telecommunication services are measured in non- virtualized and virtualized environments to better understand the impacts of virtualization on the services. Two hypervisors, i.e. KVM and XEN, are used to grasp their characteristic behaviour of handling the services. Furthermore, performance of live migration is assessed for both hypervisors using miscellaneous test cases to identify which one has the best overall performance in terms of downtime and total migration time.

The objective of this research is to study peoples’ reasons for rural-urban migration in the Babati district of Tanzania and the outcomes of such a migration on the migrants’ quality of life in Babati town. This qualitative study is based on semi-structured interviews and secondary sources. The interviews were performed with poor people in urban Babati town and two villages in rural Babati district. In the last thirty years the population of Babati town has increased more than threefold. The causes of rural-urban migration to Babati town are to be found in economical, social and cultural factors. The economic predominate, with the search for employment mentioned by all the migrants in the study. The migrants in Babati town emphasized adequate housing as a very important factor for a good life in town. This need was in many cases not fulfilled. Many were also still lacking social services and could not afford to buy basic necessities. The greatest asset for the people who have moved to Babati town was the diverse market of employment. The benefits of living in Babati town seem to outnumber the problems for most of the urban migrants. For the villagers of Mutuka the greatest asset was good natural conditions for agriculture and lifestock. In Magugu a great advantage was trade, the affordability of houses, food and necessary things. Due to differences of the dynamics of the two villages the people of Mutuka were more eager to move to Babati town than the inhabitants of Magugu. Small harvests and an insufficient market for farming products were great concerns as well as lack of social services.

Cette thèse ambitionne de contribuer à la compréhension de l’accès aux soins des bamakois selon leur statut migratoire. En effet, malgré la part importante de la population de Bamako d’origine migrante, nous avons très peu de connaissances sur leur accès aux soins. A partir des données récoltées sur le terrain et auprès des institutions maliennes et en nous basant sur des outils et des méthodes géographiques et géomatiques, nous avons pu analyser l’accès aux soins des bamakois selon leur statut migratoire.S’il est incontestable que les services de santé et en particulier ceux de base sont abondants et bien répartis à Bamako, il faut noter qu’ils souffrent de plusieurs problèmes comme la question de disponibilité permanente de personnel qualifié, la qualité des services et les dysfonctionnements entre structures de santé. Malgré l’abondance de l’offre de soins à Bamako, le taux de recours y reste trop faible. Cela confirme encore que l’accès aux soins ne se limite pas à la disponibilité physique des structures de santé. Le renoncement aux soins s’explique par une imbrication de facteurs même si la perception de la gravité de la maladie, la position dans le ménage et la profession apparaissent plus. Si l’étude n’a pas relevé de différences notoires dans l’accès aux soins selon le statut migratoire des populations, elle a tout de même montré que les stratégies de recours et l’état de santé évoluent avec la durée de résidence à BamakoThis thesis aims to contribute to the understanding of Bamako people’s access to healthcare according to their migratory status. Indeed, despite the large share of Bamako’s populations of migrant origin, we have little knowledge of their access to health services. With geographic and geomatic tools and methods, we were able to study access to health services for native and migrant populations of Bamako. While it is undeniable that health services and especially basic services are abundant and well distributed in Bamako, it should be noted that this offer suffers from several problems such as the permanent availability of qualified personnel, the quality of services offered and the dysfunctions between health structures. Despite the abundance of healthcare in Bamako, the recourse rate remains too low. This shows that access to care is not limited to the physical availability of health facilities. The renunciation of care is explained by an interweaving of factors even if the perception of the severity of the disease, the position in the household and the profession appear more. If the study did not find notorious differences in the access to the care according to the migratory status of the population, it nevertheless showed that recourse strategies and health status change with length of residence in Bamako

In this thesis we will identify which are the desired features and functionalities for implementing a system capable of acting as an information bridge for content available in the “wired” Internet to be delivered to mobile devices. We will also explore how to design and build such a system based on the specifications within parts of the MUSIS project. The MUSIS’ system development is used as a base of the work described in this thesis and the experiences from those efforts are used in order to design a system with more focus on data portability and media migration.
During the development of the MUSIS platform, problems related to system upgrading, i.e. adding new ad-hoc functionalities were discovered. Due to the fact that a user-centred design approach was taken, this was essential in the project. To solve some of these issues, we propose a new component-based system with a high level of scalability and re-usability. We name this system Collect, Convert and Send, CCS. The system shall be seen as a base that can be used as a core system for different projects where interoperability of content between different platforms, devices or systems is important.
The implementation of the system is based on the use cases and those theoretical aspects and ideas related to component software, interoperability, media migration and metadata in a Web service context. The results of our efforts give some indications that the use of component software gives a foundation for a service-oriented architecture.

Sexual violence is a prominent issue worldwide, especially during times of war and conflict. For refugee women, experiences with sexual violence are often incorporated in women’s reasons for forced migration. During the immigration process to Canada, refugee women are asked to share their narratives, at which point they may or may not disclose their histories of sexual violence. In June 2012, the Canadian government made substantial cuts to the Interim Federal Health Program. For refugee women who are survivors of sexual violence, this means that they are further limited in accessing services they might require in order to deal with the sexual violence they have experienced. Drawing from interviews we conducted with key informants (n=15) and refugee women (n=12) in both Toronto and Ottawa, this thesis explores both the lived experiences of refugee women and the changes, if any, that should be made to current service delivery. Our results show that there is a pronounced need for both small- and large-scale improvements at the systems and service delivery levels.

Mon travail de thèse s’intéresse au rétablissement de la continuité de la migration piscicole dans des réseaux d'irrigations, et plus particulièrement le cas des marais littoraux fortement régulés. Nous traitons le cas particulier du marais de Charras (estuaire de La Charente), et comme espèce cible nous nous intéressons à l’Anguille (a son stade de développement communément appelé civelle). Il s’agit d’un marais où l’écoulement est fortement régulé par des ouvrages de régulations: portes à flots, clapets, vannes. Or ces ouvrages sont des obstacles à la libre circulation des civelles. Dans un premier temps, nous nous sommes intéressés à la description du fonctionnement des ouvrages spécifiques à la gestion de l’eau dans les réseaux côtiers (portes à flots et clapet), et des solutions hydromécaniques permettant leurs franchissements (cale, raidisseur, et flotteur). Nous avons développé un modèle de fonctionnement de ces ouvrages permettant de dimensionner et comparer les solutions hydromécaniques existantes. Puis dans un second temps, nous avons étudié le comportement de la civelle au niveau des vannes. Nous avons vérifié, in-situ, la limite de vitesse de nage des civelles établie en laboratoire. Et nous avons mis en évidence que des modifications d’écoulement locales à l’aide de rugosités ne permettaient pas d’améliorer le franchissement des civelles. La troisièmes partie est consacrée à l’amélioration du passage des civelles aux niveaux d'ouvrage d’étagement (vannes et seuils) par modification de leurs gestions. Un modèle hydraulique basé sur les équations de Saint-Venant 1D du marais de Charras a été réalisé. Il permet d’évaluer l’impact des modifications de gestions des ouvrages de contrôle (porte à flot, clapet, vanne,…) sur les paramètres hydrauliques contraints par les besoins d’exploitation (ici les hauteurs d’eau, et les débit) et les grandeurs physiques de l’écoulement contrôlant le passage des civelles au niveau des ouvrages d’étagement (ici la vitesse de l’écoulement). Une quatrième partie présente plusieurs campagnes de suivi de conductimétrie dans le marais de Charras. Ils ont été mis en place pour évaluer l’impact du rétablissement de la continuité de la migration piscicole sur un réseaux hydrographique d’eau douce. Ils mettent en évidence que les solutions de franchissement piscicole permettent des intrusions salines qui complexifient l’écoulement: il est alors fortement stratifiéThis PhD thesis investigates the fish migration continuity restoration in irrigation network, more specifically the highly regulated coastal marshes. We consider the study case of the Charras marsh (Charent estuary), and we focus on the eel migration (in particular on its lifestage part called glass eel). It is a highly regulated marsh where the flow regulate whiwh hydraulics structures: tide gates, flap gates, sluices gates. These structures are obstacles to glass eel migration. We start by studing specific structures for water management in coastal networks (flood gates and flap gates), and hydromechanical solutions for fish passage (blocks, stiffeners and floats). We propose an operating model for these specific structures that takes these hydromechanical solutions for fish passage into account. The model makes it possible to evaluate the impact of these solutions on the passabilities for fish, and on their performance in terms of hydraulic regulation. Then we studied the glass eel behaviour in front of a sluice gate. We verified, in situ, the swimming speed limit of the glass eel established by laboratory studies. And we showed that local flow modifications using roughnesses did not improve glass eel passage at sluice gate. The third part is devoted to the improvement of the glass eel passage at sluice gates (or weirs) by modifying their management rules. To evaluate the impact of these adaptations, a model of the marsh was built, based on the one-dimensional Saint-Venant equations and appropriate gate equations. It allows to evaluate the impact of the modifications of the control structures management (gate, flap gate, sluice gate,...) on: the key hydraulic parameters for the exploitation needs (water levels and flow rates), and the physical quantities of the flow controlling the passage of the elvers at the level of the structures (Flow velocities at the hydraulic structures). A fourth part presents several conductivity monitoring campaigns in the Charras marsh. They were made to assess the impact of restoring the fish migration continuity at coastal water control structures, on a freshwater hydrographic network. They show that the fish passage solutions allow saline intrusions that modify the flow: it becomes highly stratified

Une architecture orientée services (Services-Oriented Architecture ou SOA) se base
fréquemment sur les services Web. Souvent, les progiciels et les systèmes patrimoniaux ne
supportent pas nativement les services Web. Une organisation aura la plupart du temps un
historique technologique avec lequel elle devra composer. Pour ces raisons, l’implantation
d’une SOA impliquera généralement la réingénierie de plusieurs composantes logicielles.
Elle impliquera également une connaissance des processus et de l’architecture de l’entreprise.
Les plus petites organisations n’ont pas toujours une documentation très élaborée des
processus d’affaire de l’entreprise. Ce sont des organisations qui réagissent rapidement au
changement. Afin de les encourager à utiliser une approche plus rigoureuse, il faut leur offrir
des outils efficaces et légers.
L’objectif de cette maîtrise est de concevoir une méthode légère et ouverte qui permettra aux
PME d’implanter une architecture orientée services de manière itérative et incrémentale à
l’aide des services Web et d’un cadre de développement agile. Cette méthode inclut des
activités au niveau de l’entreprise afin d’aligner les projets SOA avec les besoins d’affaires et
l’environnement technologique de l’entreprise. La stratégie utilisée pour réaliser cette
méthode est d’identifier un ensemble de méthodes existantes qui abordent ces différents
aspects, de les intégrer en une seule méthode documentée et de l’expérimenter.
Dans le cadre de ce travail, un partenaire industriel a été sollicité afin de tester et valider la
méthode. Des projets spécifiques ont été sélectionnés afin de faire la réingénierie de certaines
composantes logicielles dans le but de migrer graduellement vers une SOA. Ces tests ont
permis d’identifier des artéfacts particulièrement importants dans la méthode.
De ces travaux découlent une nouvelle méthode ouverte intégrant les activités d’architecture
d’entreprise, les activités orientées services et les activités de développement logiciel
classique. Bien que plusieurs améliorations soient toujours possibles, la méthode élaborée
dans le cadre de ces travaux est intégrée et documentée, que ce soit directement ou dans la
littérature des méthodologies originales.

Migrant women are often omitted within the migrant discourse/research, with that in mind, the research study brings to the fore migrant women's experiences when accessing public health care services within underdeveloped communities. The study explored Zimbabwean migrant women's experiences in accessing public health care services in Makhado, a small town based in Limpopo, South Africa which has only two public health care services namely, Louis Trichardt Memorial Hospital and Louis Trichardt clinic. To conduct this study, ethical clearance was obtained in November 2018 from the Department of Sociology at the University of Cape Town. The qualitative research method was adopted in collecting the data. The study conducted in-depth interviews with five Zimbabwean migrant women who had made use of the two public health care services in Makhado. Field notes, diary entry, an impromptu focus group were used to collect the study data. The sample for the study was purposively selected. The study worked with a total of twelve participants, in-depth interviews with five Zimbabwean women, and a focus group with seven health care workers. The collected data was manually transcribed and was analyzed using the framework analysis. Main themes and sub-themes were extracted from the transcribed interview scripts. The study revealed that migrants accessing the two hospitals in Makhado faced challenges such as language barriers, discrimination, and adverse health personnel attitudes based on the patient's citizenship status. Furthermore, the challenges that nurses are faced within their workplace, which include lack of resources, absenteeism, long working hours and overcrowded public health care services within their workplace contributed towards their negative attitude in assisting patients. As a result, migrants bore the challenges faced by the nurses within the public health care services. Therefore, the migrants reverted to having other alternatives such as traditional healers, churches, connections with nurses working in the hospitals, private hospitals and over the counter medication. However, participants underscored that in order for betterment within the public health care services, the following measures ought to be implemented, these include the introduction of independent centres, an increase of mobile clinics, increased number of interpreters, better working environment for the health personnel within the public health care facilities and intensive education training of the health personnel around the awareness migrant issues when accessing public health care services. Foucault's (1980) theory on power and knowledge, played a significant role in understanding the operational systems of public health care services. It also assisted in understanding how public health care services function, to exclude and control migrant patients, through the introduction of fees and required documentation to access public health care services.

Avec l'émergence de nouvelles technologies telles que le NFC (Communication à champ proche) et l'accroissement du nombre de plates-formes mobiles, les téléphones mobiles vont devenir de plus en plus indispensables dans notre vie quotidienne. Ce contexte introduit de nouveaux défis en termes de sécurité et de respect de la vie privée. Dans cette thèse, nous nous focalisons sur les problématiques liées au respect de la vie privée dans les services NFC ainsi qu’à la protection des données privées et secrets des applications mobiles dans les environnements d'exécution de confiance (TEE). Nous fournissons deux solutions pour le transport public: une solution utilisant des cartes d'abonnement (m-pass) et une autre à base de tickets électroniques (m-ticketing). Nos solutions préservent la vie privée des utilisateurs tout en respectant les exigences fonctionnelles établies par les opérateurs de transport. À cette fin, nous proposons de nouvelles variantes de signatures de groupe ainsi que la première preuve pratique d’appartenance à un ensemble, à apport nul de connaissance, et qui ne nécessite pas de calculs de couplages du côté du prouveur. Ces améliorations permettent de réduire considérablement le temps d'exécution de ces schémas lorsqu’ils sont implémentés dans des environnements contraints par exemple sur carte à puce. Nous avons développé les protocoles de m-passe et de m-ticketing dans une carte SIM standard : la validation d'un ticket ou d'un m-pass s'effectue en moins de 300ms et ce tout en utilisant des tailles de clés adéquates. Nos solutions fonctionnent également lorsque le mobile est éteint ou lorsque sa batterie est déchargée. Si les applications s'exécutent dans un TEE, nous introduisons un nouveau protocole de migration de données privées, d'un TEE à un autre, qui assure la confidentialité et l'intégrité de ces données. Notre protocole est fondé sur l’utilisation d’un schéma de proxy de rechiffrement ainsi que sur un nouveau modèle d’architecture du TEE. Enfin, nous prouvons formellement la sécurité de nos protocoles soit dans le modèle calculatoire pour les protocoles de m-pass et de ticketing soit dans le modèle symbolique pour le protocole de migration de données entre TEEThe increasing number of worldwide mobile platforms and the emergence of new technologies such as the NFC (Near Field Communication) lead to a growing tendency to build a user's life depending on mobile phones. This context brings also new security and privacy challenges. In this thesis, we pay further attention to privacy issues in NFC services as well as the security of the mobile applications private data and credentials namely in Trusted Execution Environments (TEE). We first provide two solutions for public transport use case: an m-pass (transport subscription card) and a m-ticketing validation protocols. Our solutions ensure users' privacy while respecting functional requirements of transport operators. To this end, we propose new variants of group signatures and the first practical set-membership proof that do not require pairing computations at the prover's side. These novelties significantly reduce the execution time of such schemes when implemented in resource constrained environments. We implemented the m-pass and m-ticketing protocols in a standard SIM card: the validation phase occurs in less than 300ms whilst using strong security parameters. Our solutions also work even when the mobile is switched off or the battery is flat. When these applications are implemented in TEE, we introduce a new TEE migration protocol that ensures the privacy and integrity of the TEE credentials and user's private data. We construct our protocol based on a proxy re-encryption scheme and a new TEE model. Finally, we formally prove the security of our protocols using either game-based experiments in the random oracle model or automated model checker of security protocols

Dans la tendance d'Internet, nous commençons à compter nos activités quotidiennes sur les systèmes de base en nuage pour stocker nos données et pour suivre tout notre état et comportement lors de l'utilisation de services Web. Par conséquent, nos données ne sont plus sécurisées comme auparavant, car nous avons délégué la responsabilité de les protéger, de les sécuriser et de les stocker à des tiers. Ces dernières années, de grandes entreprises telles que Yahoo, Facebook ou LinkedIn ont été victimes de plusieurs fuites, ce qui montre à quel point nous sommes vulnérables. Nous disposons aujourd'hui d'appareils mobiles plus puissants que jamais. Cependant, nous n'explorons pas leurs capacités en matière de traitement, de stockage et de mesures de sécurité pour utiliser les services Web localement. De plus, nos appareils sont fondamentalement divisés en deux mondes différents, ceux avec Android et ceux avec un système d'exploitation iOS. Néanmoins, avec la popularité de la technologie mobile, notre comportement a changé. Aujourd'hui, il est courant de trouver un utilisateur utilisant deux ou trois appareils mobiles en même temps, souvent avec un système d'exploitation différent. Par conséquent, nous sommes simultanément confrontés à un environnement à plusieurs périphériques avec le même système d'exploitation ou des systèmes d'exploitation différents, dans lequel la plupart des technologies et des services Web nécessitent le recours à un fournisseur tiers pour la synchronisation et le maintien de l'état de nos tâches quotidiennes. Bien que ce scénario chaotique concerne plusieurs appareils et systèmes d'exploitation, il existe une technologie mentionnée précédemment à la fin des années 90, appelée Liquid Software, qui pourrait être une solution pour harmoniser ce scénario. Le Liquid Software vise à permettre une migration fluide vers différents appareils avec ou sans le même système d'exploitation, tout en préservant l'expérience utilisateur d'une application ou d'un service donné. Dans cette thèse, basée sur les principes de Liquid Software, nous nous concentrons sur un environnement multi-périphériques capable de synchroniser le service Web côté client sans dépendre d'un système de base Cloud. Nous avons proposé une architecture basée sur des modèles, appelée Le CUBE, qui utilise des principes centrés sur l'utilisateur combinés à différentes technologies, telles que les principes REST et RESTful. Le CUBE propose également un modèle à quatre couches dans lequel REST et RESTful fonctionnent indépendamment l'un de l'autre mais en coopération. Un autre élément critique du CUBE est la couche de conversation (CC), modélisée dans le but de permettre la modification des données / états à partir des services Web. La CC utilise des techniques de traitement du langage naturel pour trouver et définir des services Web adaptés à l'utilisateur. Une autre contribution du CUBE est la création d'une sorte de réseau d'utilisateurs appelé INNER CUBE, avec tous les appareils mobiles appartenant à un seul utilisateur. Le but de la combinaison de ces éléments au sein d'une seule unité, le CUBE, est de permettre le transfert fluide de services/données et de sessions d'appareils (ordinateurs de bureau, ordinateurs portables et téléphones mobiles) vers d'autres appareils, quel que soit leur système d'exploitation, et au même temps, entièrement transparent pour l'utilisateur final, tout en réduisant la dépendance du fournisseur tiers. Nous avons également proposé deux tests pour valider le modèle CUBEWithin the trend of the Internet, we start to rely our daily activities on Cloud Base Systems to store our data and keep tracking all our state and behavior while using Web Services. Therefore, our data are no longer safe as before since we have delegated the responsibility to keep them safe, secure, and stored by third-party providers. In the last few years, big companies such as Yahoo, Facebook, or LinkedIn were victims of several leaks, which demonstrates how vulnerable we are. We have nowadays more powerful mobile devices than ever before. However, we do not explore their capacities regarding processing, storage, and security measures to using Web Services locally. Moreover, our devices are basically divided into two different worlds, those with Android, and those with an iOS operating system. Nevertheless, with the popularity of mobile technology, our behavior has changed. Today it is common to find a user using two or three mobile devices at the same time, and often they have a different operating system. Therefore, we are facing simultaneously a multiple-device environment with the same or different operating systems, where most of the technology and Web Services requiring a third-party provider to synchronizing and keep the state of our daily tasks. Although of this chaotic scenario regarding multiples devices and operating systems, there is a technology earlier mentioned at the end of 90's called Liquid Software that may be a solution to bring harmony to this scenario. The Liquid Software aims to allow for fluently migrate towards different devices with or without the same operating system, and at the same time keep the user-experience of a given application or service. In this thesis, based on Liquid Software principles, we focus on multiple devices environment able to synchronize Web Service at the client-side without depending on a Cloud Base System. We proposed the model-based architecture, called the CUBE, that makes use of User-Centric principles combined with different technologies, such as REST and RESTful principles. The CUBE also proposes a four layers model where REST and RESTful work independently from each other but in cooperation. Another critical element of the CUBE is the Conversation Layer (CL), modeled with the purpose to allow change data/state from Web Services. The CL makes use of techniques of Natural Language Processing to find and defining suitable Web Services to the user. Another contribution of the CUBE is creating a kind of user-network called INNER CUBE with all mobile devices that belong to a single user. The aim of combining these elements inside a single unit, the CUBE, is to allow for fluently move services/data and sessions from devices (desktops, laptops, and mobiles phones) to other ones regardless of their operating system, and at the same time, entirely transparent for the final user, and also reducing the dependency of the third-party provider. We have also proposed two tests to validate the CUBE model

Cette thèse s’intéresse à la gestion des ressources dans les Systèmes de Transport Intelligents Coopératifs (C-ITS) utilisant les communications V2X (vehicle-to-everything) ou Véhicule-à-Tout. Nos contributions tirent profit des technologies émergentes telles que l'Intelligence Artificielle (IA), le tranchage de réseau (Slicing) et le Multi-access Edge Computing (MEC). Ces technologies promettent de révolutionner la manière dont les réseaux véhiculaires gèrent la sécurité et l'efficacité du trafic routier et permettent de résoudre certains défis liés à l’optimisation des ressources réseaux. Le premier défi majeur abordé dans cette thèse concerne la dégradation de la qualité des canaux de communication dans les réseaux V2X congestionnés. Cette situation, fréquente dans les environnements de trafic dense, affecte négativement les performances des communications véhiculaires, entravant ainsi l'efficacité des services C-ITS. Le deuxième défi est de garantir une latence ultra-faible de bout-en-bout dans ces réseaux encombrés, en particulier pour des services et des groupes d'utilisateurs nécessitant une priorité élevée. Ce besoin est particulièrement crucial dans les scénarios où des véhicules, tels que ceux des services d'urgence, exigent une communication fiable et à faible latence. La troisième problématique traitée est la migration de services dans les réseaux véhiculaires équipés de MEC, un aspect essentiel pour assurer la continuité des services dans des environnements à mobilité élevée. La nature mobile des réseaux véhiculaires, combinée à une couverture limitée des serveurs Edge, pose des défis significatifs en termes de maintien d’un bon niveau de Qualité de Service (QoS) et de minimisation des interruptions de service. Pour relever ces défis, la thèse propose trois contributions majeures. Premièrement, une approche proactive pour le Contrôle de Congestion Décentralisé (DCC) a été développée en utilisant des réseaux neuronaux récurrents avec Long Short-Term Memory (LSTM). Cette technique vise à optimiser les performances du canal en prévoyant en amont le Taux d'Occupation du Canal (CBR) pour améliorer la stabilité du réseau tout en garantissant une allocation équitable des ressources. Les simulations ont démontré l'efficacité des algorithmes DCC proactifs, montrant une convergence plus rapide et une meilleure gestion de l’allocation des ressources. Ensuite, nous avons abordé le tranchage de réseau dans les communications véhiculaires utilisant la technologies ITS-G5. Pour cela, nous avons proposé une architecture de tranchage de la partie RAN ITS-G5 (Radio Access Network), visant à créer des tranches réseaux avec des V priorités variées, tout en garantissant l'isolation des performances et le respect de niveau de QoS entre les tranches. Cette approche vise à maintenir des niveaux de performances et de sécurité adéquats pour chaque tranche, même en présence de services d'exigences de QoS contradictoires. Au-delà de la partie RAN, nous avons élaboré une architecture de tranchage de réseau de bout-en-bout (RAN et Core Network), visant à garantir des latences faibles pour des groupes d'utilisateurs spécifiques, notamment dans les zones encombrées. Les simulations ont confirmé l'efficacité de cette architecture dans la gestion du flux de trafic et la réduction de la latence pour les services à haute priorité, démontrant l'importance de ces approches dans l'avancement des réseaux véhiculaires intelligents et efficaces. La dernière contribution aborde la migration de services dans les réseaux véhiculaires équipés de MEC. Nous avons formulé ce problème de migration en tant que Processus Décisionnel Markovien (MDP) et avons développé une stratégie de migration adaptative en utilisant l'apprentissage par renforcement profond (DRL), notamment les approches Deep Q Networks (DQN) et Double Deep Q Networks (DDQN). Cette stratégie vise à trouver l’équilibre optimal entre la latence et le coût de migration.[...]This thesis unfolds in the dynamic context of Cooperative Intelligent Transport Systems (C-ITS) and Vehicle-to-Everything (V2X) communications, with a particular focus on the integration of emerging technologies such as Artificial Intelligence (AI), Network Slicing, and Multi-access Edge Computing (MEC). These revolutionary technologies are reshaping the way vehicular networks manage traffic safety and efficiency while presenting unique challenges. The first major challenge addressed in this thesis is the degradation of communication channel quality in congested V2X networks. This common situation in dense traffic environments negatively impacts vehicular communication performance, thus hindering the efficiency of C-ITS. The second challenge is to ensure ultra-low end-to-end (E2E) latency in these congested networks, particularly for services and user groups requiring high priority. This need is especially crucial in scenarios where vehicles, such as emergency services, rely on rapid and reliable communication. The third significant issue tackled is service migration in MEC-enabled vehicular networks, an essential aspect to ensure service continuity in highly mobile environments. The mobile nature of vehicular networks, combined with the limited coverage of edge servers, poses significant challenges in maintaining QoS and minimizing service interruptions. To address these challenges, the thesis proposes several innovative solutions. A proactive approach for Decentralized Congestion Control (DCC) was developed using Long Short-Term Memory (LSTM) recurrent neural networks. This technique aims to optimize channel performance by forecasting the Channel Busy Ratio (CBR), thus improving network stability and ensuring fair resource allocation. Simulations demonstrated the effectiveness of proactive DCC algorithms, showing faster convergence and better resource management. Next, we address the innovative aspects of network slicing in ITS-G5 vehicular communications. The second contribution proposes an ITS-G5 RAN slicing architecture, aiming to create slices with varied priorities for efficient and secure traffic, while ensuring isolation and prioritization between slices. This approach aims to maintain performance and security for each slice, even in the presence of conflicting services. In the third contribution, we develop an end-to-end network slicing architecture, aiming to improve latency for specific user groups, particularly in congested areas. Simulations confirmed the effectiveness of these architectures in traffic flow management and latency reduction for high-priority services, demonstrating the importance of these approaches in advancing intelligent and efficient vehicular networks. III Finally, to address service migration in MEC vehicular networks, we formulated the problem as a Markov Decision Process (MDP) and developed an adaptive migration strategy using Deep Reinforcement Learning (DRL), specifically Deep Q Networks (DQN) and Double Deep Q-network (DDQN) approaches. This strategy aims to balance migration costs and latency. Simulation results showed that the DDQN method excels in managing migration costs while maintaining optimal QoS, particularly for latency-sensitive services, and offers an optimal balance for high-priority services. These contributions, combining technological advances and innovative analytical approaches, provide robust solutions to current and emerging challenges in cooperative intelligent transport systems, paving the way for significant improvements in road safety, traffic efficiency, and user experience in the field of smart mobility

During the second half of 2015, Sweden experienced the largest inflow of asylum-seekers in its history. Almost 163,000 people sought asylum in 2015, whereof approximately 70,000 children. The influx challenged the reception system and severe child protection concerns such as disappearances and sexual exploitation of unaccompanied minors were identified. Half of the children that arrived in 2015 came with families but this group have received less attention so far. The aim of this study was to explore the child protection systems around asylum-seeking and returning children in families by identifying child protection concerns and existing gaps in the services provided to this target group. Fourteen semi-structured interviews with twenty individuals belonging to various stakeholder groups such as staff at asylum accommodations, social workers, parents and, volunteer and staff from civil society organisations were conducted in two municipalities in Skåne, Sweden. The data was analysed using thematic analysis and the results are discussed in regards to the Protective Environment Framework. The results suggest that children in migration, with families, face multiple protection concerns in Sweden. Significant gaps exist in the services provided to these children and there are large disparities between accommodation centres. Many accommodations fail to provide a child-friendly environment and gender separated sanitation facilities. Furthermore, the results point out the importance of increasing competence of child protection among actors, and to increase preventive measure directed towards the parents in order to ensure a protective and safe environment for children.

Canada has been active in attracting highly-skilled, foreign-trained workers to overcome its labour shortage, facilitate its economic growth, and enhance its global competency. While promoting gender equality in the workplace and advancing women’s labour market participation are ongoing focuses of Canada’s attention, the arrival of an increased number of skilled immigrant women and their marginalized experiences in the Canadian labour market reflects a critical problem that the underuse of highly skilled immigrant women’s professional skills might be a loss for both Canada and individual immigrants.
This research reveals the lived experience of highly skilled Chinese immigrant women in the Canadian labour market, and analyzes how the barriers to their career restoration were constructed. It adopts Seyla Benhabib’s weak version of postmodern feminist theory and Dorothy Smith’s Institutional Ethnography methodology. Based on interview data with 46 highly skilled Chinese immigrant women, this research identifies these immigrant women’s standpoint within the institutional arrangements and understands the barriers to their career restoration as discursively constructed outcomes. This research contends that the settlement services for new immigrants funded by the federal government fall short of meeting the particular needs of highly skilled immigrants who intend to find highly skilled jobs that match their qualifications. This research also makes recommendations for improving existing language training and employment-related settlement services in order to better assist highly skilled immigrants in using their skills to a larger extent.

L'avènement des Systèmes de Transport Intelligents (STI) marque un changement de paradigme dans l'approche de la gestion et de l'optimisation des infrastructures de transport. Ancrés dans l'intégration des technologies de communication de pointe, les STI englobent une variété d'applications visant à améliorer la sécurité routière, l'efficacité du trafic et le confort de conduite. Cependant, l'exécution de ces applications de plus en plus gourmandes en calcul pose des défis inhérents liés à la latence, au traitement des données, et à la continuité des services. L'émergence de l'Edge Computing se présente comme une avancée transformatrice prête à redéfinir l'efficacité des applications véhiculaires dans les Systèmes de Transport Intelligents (STI). En contraste avec les paradigmes conventionnels de Cloud Computing, qui rencontrent fréquemment des problèmes de latence attribuables à la nature distante du traitement des données, l'Edge Computing décentralise les tâches computationnelles pour être plus proche du point de génération des données. Cette proximité réduit drastiquement la latence, optimise l'agrégation des données, et améliore l'utilisation globale des ressources. Par conséquent, l'Edge Computing est idéalement positionné pour adresser et potentiellement atténuer les limitations qui ont précédemment entravé l'optimisation des fonctionnalités des STI. Néanmoins, l'incorporation de l'Edge Computing dans les réseaux véhiculaires révèle un éventail unique de complexités, allant du placement stratégique des serveurs de bord et des techniques efficaces de déchargement de données à la mise en œuvre de protocoles robustes de migration de services et la sauvegarde des mesures de confidentialité et de sécurité.Cette thèse examine les problèmes de placement des serveurs Edge et de migration des services dans l'architecture de l’Edge Computing pour véhicules. Nos contributions dans cette thèse sont triples. Premièrement, nous introduisons "ESIAS", un Système d'Assistance de Sécurité à l'Intersection basé sur l'Edge, spécialement conçu pour améliorer la sécurité des intersections. Le système vise à distribuer proactivement des messages d'avertissement précis aux conducteurs, atténuant ainsi le risque d'accidents courants liés aux intersections. Deuxièmement, nous abordons le défi du placement optimal des serveurs en bordure dans les réseaux véhiculaires, en utilisant la programmation linéaire en nombres entiers pour trouver les solutions les plus efficaces. La méthodologie prend en compte la latence, le coût et la capacité des serveurs dans des conditions de trafic réelles. Le cadre proposé vise non seulement à minimiser le coût global de déploiement, mais aussi à équilibrer les charges de travail computationnelles entre les serveurs en bordure, tout en maintenant la latence dans des seuils acceptables. Enfin, nous nous plongeons dans la question complexe de la migration des services dans les réseaux véhiculaires, en abordant le dilemme du maintien de la qualité de service (QoS) tout en minimisant les coûts de migration. À mesure que les véhicules se déplacent à travers différentes régions, le maintien de la qualité du service nécessite une migration de service stratégique, qui pose des défis en termes de timing et de localisation. Pour résoudre ce problème, nous formulons le problème en tant que processus décisionnel de Markov (PDM) et appliquons des techniques d'apprentissage par renforcement profond, spécifiquement les Deep Q Networks (DQN), pour découvrir des stratégies de migration optimales adaptées aux exigences de chaque service. Le cadre résultant assure une continuité de service transparente, même dans des contraintes de haute mobilité, en réalisant un équilibre optimal entre la latence et les coûts de migrationThe advent of Intelligent Transportation Systems (ITS) marks a paradigm shift in the approach to managing and optimizing transportation infrastructures. Rooted in the integration of state-of-the-art communication technologies, ITS encompass a variety of applications aimed at enhancing road safety, traffic efficiency, and driving comfort. However, the execution of these increasingly computation-intensive applications raises inherent challenges related to latency, data processing, and service continuity. The emergence of Edge Computing stands as a transformative advancement poised to redefine the efficacy of vehicular applications in Intelligent Transportation Systems (ITS). Contrasting with conventional cloud computing paradigms, which frequently encounter latency issues attributable to the remote nature of data processing, Edge Computing decentralizes computational tasks to be nearer to the point of data generation. This proximity drastically diminishes latency, optimizes data aggregation, and enhances overall resource utilization. Consequently, Edge Computing is uniquely positioned to address and potentially mitigate the limitations that have previously impeded the optimization of ITS functionalities. Nevertheless, the incorporation of Edge Computing into vehicular networks unveils a unique array of complexities, ranging from the strategic placement of edge servers and efficient data offloading techniques to the implementation of robust service migration protocols and safeguarding privacy and security measures.This thesis investigates the problems of edge server placement and service migration in vehicular networks. Our contributions in this thesis are threefold. First, we introduce "ESIAS," an Edge-based Safety Intersection Assistance System, specifically designed to improve safety intersections. The system aims to proactively distribute precise warning messages to drivers, mitigating the risk of common intersection-related accidents. Second, we tackle the challenge of optimal Edge server placement in vehicular networks, employing integer linear programming to find the most effective solutions. The methodology considers latency, cost, and server capacity in real-world traffic conditions. The proposed framework aims not only to minimize the overall deployment cost but also to balance the computational workloads among Edge servers, all while maintaining latency within acceptable thresholds. Finally, we delve into the complex issue of service migration in MEC-enabled vehicular networks, addressing the quandary of maintaining quality of service (QoS) while minimizing migration costs. As vehicles move through different regions, maintaining service quality requires strategic service migration, which poses challenges in terms of timing and location. To resolve this problem, we formulate it as a Markov Decision Process (MDP) and apply deep reinforcement learning techniques, specifically Deep Q-Networks (DQN), to discover optimal migration strategies tailored to each service's requirements. The resulting framework ensures seamless service continuity even within high-mobility constraints, achieving an optimal balance between latency and migration costs

The objectives of this study were to measure and describe the overall satisfaction of Hispanics/Latinos with services they receive from Chesterfield County's Health Department and compare it to that of African Americans and Caucasians. Also, the objectives were to analyze reasons for different levels of satisfaction, assess the nature and degree of satisfaction with particular services, and suggest implications of the Hispanic/Latino opinions for public policy. While the empirical literature revealed that Hispanics/Latinos experience lower levels of satisfaction with health care services, this study did not provide evidence to support this theory.This is a multi-method non-experimental research design combining a cross-sectional design and qualitative interviews. Quantitative data was collected through a patient satisfaction survey, in both English and Spanish, incorporating both closed and open-ended questions. Qualitative data was collected through taped in-depth interviews conducted with each subject to obtain their perspective on the services provided by the Health Department.The Spanish and English research instrument (Appendix C and D) was a self-designed survey to provide a more comprehensive approach to assess customer satisfaction of health services, collect demographic information, and determine how to better deliver these services. The survey consisted of 46 questions (and several follow-up questions) with 23 questions pertaining to the six satisfaction dimensions. These dimensions were measured by a Likert-type response scale ranging from strongly agrees to strongly disagree.Item identification was based on suggestions offered by staff of Chesterfield County's Health Department, theoretical concepts introduced in the literature review and miscellaneous information adapted from the following surveys: The Connecticut Surgical Group - Patient Satisfaction Survey (2004); SERVQUAL--an instrument for measuring quality service (1990); and The Patient's View on Health Care by RAND and UMQC (1994). Authors of these surveys suggest satisfaction be assessed across the following dimensions: reliability, responsiveness, competence, access, courtesy, communication, credibility, security, understanding/knowledge of the customer, and tangibles (appearance of physical facilities). Data were collected from 166 non-Hispanic/Latino and 90 Hispanic/Latino patients that were 18 years of age or older and receive services, at Chesterfield County, Virginia's Health Department. The independent variables were sex, age, level of school completed, income, marital status, children, ethnic background, ability to speak English, modes of transportation, and length of residency in Chesterfield County, Virginia. Dependent variables in the analyses included the six dimensions of satisfaction--staff reliability, staff responsiveness, staff courtesy, staff communication, access to Health Department services, and Health Department Facilities. The data were analyzed through several inferential statistical techniques--univariate, bivariate, multivariate, and nonparametric.Results of the tests indicated that overall, ethnic background only influenced satisfaction with services across two dimensions--staff responsiveness and staff courtesy. However, there were noted differences in the measured levels of satisfaction across the racial/ethnic groups. This study also found that valid comparisons can be made among Hispanics/Latinos, African Americans, and Caucasians on their levels of satisfaction using the 23 measures. Population characteristics had no influence on the differences in satisfaction among the racial ethnic/groups. Results of the in-depth interview revealed that respondents were satisfied with the services as well as the quality of the services provided by the Health Department.

Les travaux décrits dans cette thèse de doctorat visent à traiter les futures architectures de fourniture de services mobiles basés sur le cloud, à travers l'évolution des infrastructures réseau partant de Mobile Cloud Computing (MCC) au Mobile Edge Computing (MEC). Nous nous sommes essentiellement concentrés sur le concept Follow Me Cloud (FMC) comme une nouvelle stratégie de fourniture de services pour une meilleure expérience utilisateur et une utilisation efficace des ressources. Cela permet aux services basés sur le cloud de "suivre" leurs utilisateurs mobiles au cours de leurs déplacements à travers les technologies de réseau d'accès, tout en fournissant le service basé sur le cloud via le point de service le plus optimal au sein de l'infrastructure cloud. Plusieurs contributions sont proposées dans cette thèse, avec des évaluations à la fois en analyse théorique et en simulation scientifique.Premièrement, nous avons proposé une architecture alternative FMC qui permet: (i) d'ouvrir la conception FMC sur les technologies d'accès réseau mobile non-3GPP (ii) d'assurer l'interopérabilité entre différents domaines PMIPv6 permettant au MN une itinérance inter-domaines PMIPv6 avec une mobilité IP transparente ainsi qu'une continuité de session de service.(iii) d'offrir une architecture sans tunnel dans les situations d'itinérance de MN, en évitant ainsi toute surcharge supplémentaire liée aux tunnels dans la gestion de la mobilité. Le schéma proposé exploite la technologie SDN/OpenFlow et le protocole de gestion de la mobilité PMIPv6 en les intégrant dans un unique framework permettant de réaliser la vision FMC.Deuxièmement, pour aborder les problèmes d'évolutivité et de résilience dans les architectures SDN/OpenFlow centralisées de plan de contrôle, nous avons introduit une nouvelle conception d'un contrôleur SDN élastique et distribué adapté pour MCC et plus particulièrement pour les systèmes de gestion FMC. Nous avons illustré comment le nouveau schéma de plan de contrôle est distribué sur une architecture hiérarchique à deux niveaux, un premier niveau avec un seul contrôleur SDN global et un second niveau avec plusieurs contrôleurs SDN locaux. Ensuite, nous avons présenté les éléments constitutifs de notre nouvel framework de plan contrôle, le calcul de l'indicateur de performance (KPI) du système, et nous avons fixé l'objectif clé de notre conception visant à maintenir la valeur KPI du système dans une fenêtre de seuil prédéfinie. Enfin, nous avons démontré comment cet objectif est atteint en adaptant dynamiquement le nombre et l'emplacement des contrôleurs SDN locaux en utilisant la technologie NFV pour provisionner les contrôleurs SDN en tant que instances VNF (fonction réseau virtuelle) dans le cloud.Troisièmement, nous avons introduit le concept FMeC, exploitant les capacités offertes par la combinaison des architectures MEC et FMC dans le but de satisfaire aux exigences des systèmes automobiles 5G. Nous avons commencé par définir les éléments clés du concept FMeC permettant de fournir la technologie FMC en bordure des réseaux mobiles. Ensuite, nous avons présenté une projection de notre solution FMeC sur un cas d'utilisation de conduite automatisée intégrant l'industrie automobile aux infrastructures Telecom en vue de la vision automobile 5G future. Avec une focalisation sur les types de communications V2I/N, nous avons présenté la conception de notre architecture FMeC basée sur les technologies SDN/OpenFlow et les entités de l'infrastructure MEC dont les ressources sont mises en commun pour fournir un cloud de bordure fédéré. Enfin, nous avons présenté notre framework sensible à la mobilité pour le placement des services dans le cloud de bordure, ce dernier est fondé sur un ensemble d'algorithmes de base qui permettent d'atteindre les exigences de QoS de la conduite automatisée en termes de latence ultra-courte au sein du réseau 5GThis Ph.D. thesis aims to deal with the future delivery architectures of mobile cloud-based services, through network infrastructures evolving from Mobile Cloud Computing (MCC) to Mobile Edge Computing (MEC). We mainly focused on Follow Me Cloud (FMC) concept as a new service delivery strategy for improved user experience and efficient resource utilization. That enables cloud-based services to follow their mobile users during their movement across access network technologies and by delivering the cloud-service via the optimal service point inside the cloud infrastructure. Several contributions are proposed in this thesis and evaluated in both theoretical analysis and scientific simulation.First, we proposed an alternative FMC architecture that allows: (i) to open the FMC design on non-3GPP mobile network access technologies (ii) to provide interoperability among different PMIPv6 domains permitting MNs inter-PMIPv6 domain roaming with seamless IP mobility and service session continuity (iii) to offer a tunnel-free architecture in MNs roaming situation, avoiding any additional overhead associated with tunneling in mobility management. This proposed scheme leverage SDN/OpenFlow technology and PMIPv6 mobility management protocol by integrating them within a framework permitting to realize the FMC vision.Second, to address the scalability and resiliency concerns in centralized SDN/OpenFlow control plane architecture, we introduced a new design of an elastic distributed SDN controller tailored for Mobile Cloud Computing (MCC) and more notably for Follow Me Cloud (FMC) management systems. We illustrated how the new control plane scheme is distributed on two-level hierarchical architecture, a first level with a single global SDN controller and a second level with several local SDN controllers. Then, we presented the building blocks of our novel control plane framework, the system Key Performance Indicator (KPI) computation and set the key objective of our design aiming to keep the system KPI value within a predefined threshold window. Last, we proved how this goal is achieved by adapting the number of local SDN controllers and their locations in an elastic manner and deploying them as VNF instances on the cloud thanks to NFV technology.Third, we introduced FMeC concept, leveraging the intertwining of MEC and FMC architectures with the aim of sustaining requirements of the 5G automotive systems. We began by defining FMeC key concept elements permitting to provide FMC technology at the edge of mobile networks. Then, we presented an automated driving use case projection of our FMeC solution integrating automotive with Telco infrastructures towards the future 5G automotive vision. Focusing on the V2I/N communications types, we introduced our FMeC design architecture based on SDN/OpenFlow technologies and MEC infrastructure entities whose resources are pooled together to provide a federated edge clouds. Finally, we presented our mobility-aware framework for edge-cloud service placement based on a set of basic algorithms that permit achieving the automated driving QoS requirements in terms of ultra-short latency within 5G network

This study explores undocumented migrant’s access to social welfare and income support distributed by the non-profit and public sector in Stockholm. The study is conducted through interviews with representatives from the non-profit sector whose organisations and networks come in contact with undocumented migrants. According to Swedish law the social services have a responsibility to assist everyone who temporarily resides within the county. Consequently undocumented migrants have the right to assistance in acute situations. According to the testimonies given from the non-profit sector undocumented migrants have much difficulties acquiring all forms of aid from the social services. The respondents experiences show a multi-layered complex of problems giving reason for bureaucrats representing the public authority narrowing their services to undocumented migrants. The main focal points presented in this study are bureaucrats confusion regarding their own mission in relation to the migration board as well as the services restricted resources. Since undocumented migrants have difficulties claiming their rights in regard to the public sector, many turn to the non-profit sector for support. The result in the study shows that the non- profit sector functions as an informal social service bureau without the economical or legal framework to support it.

Uppsatsen utgår ifrån hur socialarbetares vittnesmål problematiserar det sociala arbetets struktur gällande ekonomisk utsatthet bland barnfamiljer. Genom kvalitativa intervjuer undersöker studien hur barnfamiljer med svag ekonomi upplever att vardagen påverkas av deras ekonomiska situation, vad de tvingas avstå ifrån samt vilket stöd de erfarit från myndigheter och civilsamhälle. Studiens teoretiska ansats utgörs av Baumans teori om konsumtionssamhället, Goffmans Stigma, Bourdieus kapital samt Beckers stämplingsteori. Uppsatsens resultat påvisar hur familjernas upplevelser av ekonomisk utsatthet i Sverige 2018 skiljer sig ifrån varandra samtidigt som beröringspunkter kan uttydas; föräldrarnas krympta valmöjligheter att samt deras kamp för att ge sina barn möjligheter att delta i samhället på samma villkor som andra. Familjernas upplevelser av att tvingas avstå från saker som andra har av ekonomiska skäl förklarar den ekonomiska utsatthetens skiftningar och hur deprivationens omfattning varierar mellan studiens deltagare. Familjernas erfarenheter av stöd genom statliga myndigheter i samband med ekonomiska problem kan sammanfattas genom deras negativa erfarenheter av socialtjänstens bemötande. De flesta föredrar att vända sig till civilsamhällets ideella organisationer när de behöver stöd: ekonomiskt såväl som känslomässigt. Innebörden av familjernas upplevelser av att avvika från normen i konsumtionssamhället kan ifrågasätta tanken bakom en skälig levnadsnivå och statliga myndigheters förhållningssätt gentemot ekonomiskt utsatta barnfamiljer.

There is an on going debate in academia on the health of immigrants in their host countries. Many studies have indicated that immigrants tend to have poor health as compared to the native born population. Researchers in this field however hold divergent views on the causes of the poor health of immigrants. One school of thought attributes poor health of immigrants to premigration period. The contenders of this theory argue that during this period immigrants experience and are subjected to hardships which will affect their health later on in their lives. On the other hand, some researchers view post migration period as an ultimate determinant of the poor health of immigrants in their host country. These researchers ascertain that during this
period immigrants are faced with many challenges of adaptation and most often lack good integration in their host countries which hampers their health.
The aim of this study is to explore and describe the impact of migration and integration on the health of African immigrants in the Swedish society. A combination of both qualitative and quantitative methods was used to collect and analyze data with the help of the “triangulation “technique. A structured questionnaire was used as a guideline to the in-depth interviews conducted with African immigrants who have lived in Sweden for a period of five to twenty
years and plus. Twentyfive African immigrants from fourteen African countries took part in this research. This study was conducted in the city of Linköping in Sweden.
Results from this study revealed that majority of African immigrants self rated their health as being good. Many affirm to be in good health. However, a majority of African immigrants reported psychosomatic symptoms such as stress, fatigue, and other illnesses such as high blood pressure, and diabetes. It was also observed that African immigrants hardly seek medical help except when necessary. Health as defined by immigrants is “a combination of physical and
mental well being”,” health is ” happiness and joy”, health is “self realization and self esteem”, health is “vitality”, Health is a “sine qua non condition to good life”. However mastery of the Swedish language, and flexible opportunities, which will enable immigrants to access the labor market and be self-sufficient, may improve the immigrants health condition. Also integration of immigrants’ health professionals in the Swedish health care system may be a vital tool to
encourage immigrants to seek health attention and improve their health condition.

Le point de départ de cette thèse est le constat que dans les systèmes de santé post-soviétiques les paiements informels aux professionnels de santé perdurent bien au-delà de la transition post-socialiste, et ce malgré les vagues de réforme successives du système de santé.Dans le même temps depuis l'indépendance de la République du Tadjikistan, une défiance profonde envers certains professionnels de santé s'est développée et le renoncement aux soins s'est accru, touchant plus particulièrement les populations vulnérables. Quel rôle jouent alors les différentes pratiques de rémunération informelle ? Sont-elles source de défiance ou un moyen de restaurer la confiance ? Les paiements informels sont-ils ajustés au niveau de vie des patients ou source d'inégalités entre patients ?D'après les indicateurs d'équité mobilisés et contrairement aux idées reçues, les paiements informels ne permettent pas de rendre le système progressif et de garantir l'accès à tous. Les populations les plus démunies cumulent plus de renoncement aux soins.Face à ces barrières à l'accès aux soins, différentes stratégies sont mises en place par les ménages : solidarités informelles, endettement, recours à la médecine traditionnelle, mobilisation de son capital social.On étudie alors, plus précisément, dans quelle mesure la migration, phénomène massif au Tadjikistan, fait partie de ces stratégies et dans quelle mesure les remises de fonds permettent aux ménages bénéficiaires d'améliorer leur accès aux soinsThis dissertation begins with the observation that informal payments to healthcare professionals in post-soviet health systems persisted well beyond the post-socialist transition and despite the successive waves of health care reform.During this transition period, since the independence of the Republic of Tajikistan, there has been a deterioration of trust towards certain health professionals which has been associated with increased forgone care, especially among vulnerable populations. What is the role played by the different informal payment practices? Are they a source of mistrust or a means of restoring trust? Are informal payments adjusted to patients' standard of living or a source of inequality between patients?According to the equity indicators mobilized and contrary to popular belief, informal payments do not make the system progressive and do not guarantee that there will be access for all. The poorest are more likely to forgo care.To cope with these barriers in accessing care, different strategies are put in place by households: informal solidarity, indebtedness, reliance on traditional medicine, mobilization of social capital.More specifically, we then study if migration, a relatively important phenomenon in Tajikistan, is part of these strategies and to what extent remittances enable beneficiary households to improve their access to healthcare

This study considered migrants’ career outcomes as the result of their adjustments in terms of culture and career adaptation along with other positive attributes they brought on their arrival as well as developing in their new country. It considered that career is the property of individuals and managing it successfully is the responsibility of individuals themselves. Prior research into migrants’ issues and careers was used as the basis of this study and a model for analysis was developed using such issues. The resultant model included the wider life of migrants. A questionnaire including reliable measures of key variables was developed based on the literature. Two hundred and twenty-one Sri Lankan migrants completed the pilot tested survey. The results were analysed using factor analysis, tests of association and multiple regression analysis at the first stage to formulate a less complex model. Structural equation modelling was then used to confirm the relationships assumed between different variables. Although some of the relationships and/or variables assumed initially were removed from the model, the final model explained strong links between the variables that remained. Qualification gained before migration and career self-efficacy were found to be the most significant variables in explaining job satisfaction before migration. Usefulness of prior knowledge, skills and habits, efforts made towards career, education in New Zealand, information seeking, length of time in New Zealand and overseas experience had the greatest influence on current job level. Current job level, length of time in New Zealand and overseas experience were found to be the most significant variables explaining subjective career success after migration. Adapting to New Zealand culture was found to be significant in explaining only the career satisfaction after migration. It was also found that migrants’ career outcomes (success and satisfaction) after migration were significant variables in explaining overall career satisfaction of this migrant group: however, with the exception of job satisfaction, career outcomes before migration did not play a significant role in determining overall career satisfaction. The implications of the present study were considered, from both migrants’ perspective and that of New Zealand as the host society. A number of possible practical strategies relevant to migrants, community organisations and policy makers and authorities were suggested. Several potential avenues for future researches were identified and discussed. Thus, it is expected that this study will contribute to better career outcomes of migrants in New Zealand.

The present master thesis is an exploratory qualitative study in academic libraries regarding the transition from the integrated library systems to the next generation integrated library systems or library services platforms and the potential implications in their internal workflows. Nowadays, libraries all over the world are facing up with a number of challenges in terms of acquiring, describing and making available to the public all the resources, both printed and electronic, they manage. In particular, the academic libraries have more reasons to wish to fulfill their users’ needs since the majority of them use the library sources more and more for scientific research and educational purposes.In this study we attempt to explore the phenomenon in the globe using the available literature and to identify the implications in libraries’ workflows and the possible future developments. Moreover, through observation and semi-structured interviews we try to identify the current developments in the Greek context regarding the adoption of next ILS and possible implications in their workflows. Finally, we attempt a comparison between the Greek situation and the international one.

The purpose of this study is to present guidelines that can be followed when introducing Service-oriented architecture through the use of Web services. This guideline will be especially useful for organizations migrating from their existing legacy systems where the need also arises to consider the financial implications of such an investment whether it is worthwhile or not. The proposed implementation guide aims at increasing the chances of IT departments in organizations to ensure a successful integration of SOA into their system and secure strong financial commitment from the executive management. Service oriented architecture technology is a new concept, a new way of looking at a system which has emerged in the IT world and can be implemented by several methods of which Web services is one platform. Since it is a developing technology, organizations need to be cautious on how to implement this technology to obtain maximum benefits. Though a well-designed, service-oriented environment can simplify and streamline many aspects of information technology and business, achieving this state is not an easy task. Traditionally, management finds it very difficult to justify the considerable cost of modernization, let alone shouldering the risk without achieving some benefits in terms of business value. The study identifies some common best practices of implementing SOA and the use of Web services, steps to successfully migrate from legacy systems to componentized or service enabled systems. The study also identified how to present financial return on investment and business benefits to the management in order to secure the necessary funds. This master thesis is based on academic literature study, professional research journals and publications, interview with business organizations currently working on service oriented architecture. I present guidelines that can be of assistance to migrate from legacy systems to service-oriented architecture based on the analysis from comparing information sources mentioned above.
