La sécurité des futures architectures convergentes pour des services personnalisés : aspect architectural et protocolaire / Security of converging future architectures for personalized services : architectural and protocol aspects

Hammami, Ali 01 July 2013 (has links)
L’émergence et l’évolution des réseaux de nouvelles génération (NGN) a soulevé plusieurs défis surtout en termes d’hétérogénéité, de mobilité et de sécurité. En effet, l’utilisateur est capable, dans un tel environnement, d’avoir accès à plusieurs réseaux, à travers différents terminaux, avec un choix vaste de services fournis par différents fournisseurs. De plus, les utilisateurs finaux demandent à être constamment connectés n’importe où, n’importe quand et n’importe comment. Ils désirent également avoir un accès sécurisé à leurs services à travers une session dynamique, seamless et continue selon leurs préférences et la QoS demandée. Dans ce contexte, la sécurité représente une composante majeure. Face à cette session user-centric sécurisée, plusieurs défis se posent. L’environnement est de plus en plus ouvert, de multiples services ne sont pas connus d’avance et nous avons une diversité de communications entre les services et les utilisateurs. L’hétérogénéité des ressources (terminaux, réseaux et services) impliquées dans la session de l’utilisateur accentue la complexité des tâches de sécurité. Les différentes déclinaisons de mobilité (mobilité de l’utilisateur, mobilité du terminal, mobilité du réseau et mobilité du service) modifient la session user-centric que l’on veut unique, sécurisée et seamless avec la délivrance d’un service continu. / The emergence and evolution of Next Generation Networks (NGN) have raised several challenges mainly in terms of heterogeneity, mobility and security. In fact, the user is able, in such environment, to have access to many networks, via multiple devices, with a vast choice of services offered by different providers. Furthermore, end-users claim to be constantly connected anywhere, anytime and anyhow. Besides, they want to have a secure access to their services through a dynamic, seamless and continuous session according to their preferences and the desired QoS. In this context, security represents an important concern. In fact, this user-centric session should obviously be secured. However, many challenges arise. In such environment, system boundaries, which were well delimited, become increasingly open. Indeed, there are multiple services which are unknown in advance and multiple communications between services and with users. Besides, heterogeneity of involved resources (terminals, networks and services) in the user session increases the complexity of security tasks. In addition, the different types of mobility (user, terminal, network and service mobility) affect the user-centric session that should be unique, secure and seamless and ensure continuity of services.

China’s New Generation Migrant Workers

Wang, Lie 01 January 2012 (has links) (PDF)
About 45% of China’s roughly 145 million floating migrant population works in the manufacturing industry, and the majority of them were born after 1980. This was a landmark year for the country as it transform from a socialist, centralized and planned economy to a more or less market-oriented economy with so-called “Chinese characteristics.” The intersection of this new generation of migrant workers and the global market through the medium of manufacturing has become a subject of great interest to people around the world and in China, who seek to understand their unique personal and work arenas. This paper provides a comprehensive picture of the young migrant workers’ work and lives in a factory setting based on survey and in-depth interview data collected in a medium-size Shenzhen-based electronics factory in May 2010. It explores their social expectations and suffering; their satisfactions and dissatisfactions as production-line workers; and their future goals. The findings show that the new generation migrant workers migrate more out of individual preferences than family needs. They are primarily leaving home to seek independence more than economic returns, and they perceive factory work as the first stop on a long journey of establishing themselves in society. If Leaving, Remitting and Returning are the three key words that categorize the old generation of migrant workers who were born before 1980, then Leaving, Searching and Becoming are the main themes for the new generation who were born after 1980. Like their parents’ generation, they are transient in nature, but more in the sense of juggling between career choices rather than round-tripping between rural home and urban work.

Leadership in Southern Europe : The two faces of the crisis

Meslin, Anaïs, Minguela Pernía, Beatriz January 2013 (has links)
The current economic crisis that affects Europe, much deeper in the South has behind it bigger problems than purely economic. In this thesis, we advocate the existence of a crisis of leadership within the economic one, that somehow prevents nations from continue and escape from the crisis, since the solutions given are purely economic and not fix the hidden problems.We advocate for change in the form of lead as a strong support to find a solution. A better leadership from our governments is a support to overcome the crisis.In order to achieve this, in the first part of the thesis will explore the Crisis of leadership, its causes and implications, seeing his negative side. In the second we will focus on exploring the current leadership failures and how an improvement of this can be crucial to overcome the crisis. Readers will see the positive side of the crisis as an opportunity for change in leadership. In this way, we end up venturing into the new generation of leaders, the impact of the crisis in youth and why we do believe that they can get the good side of this situation.

A Study on X, Y Generation Consumers¡¦ Selection and Purchase of New Generation Game Consoles

Kao, Chi-hao 27 June 2011 (has links)
Abstract The video game consoles was accompanied with players for decades, from the video game consoles of the first generation that have simple screen and hardware, to the video game consoles of the seventh generation that have exquisite screen, online functions, and excellent hardware, players have deep impressions on these video game consoles of every generation. In the market of new generation video game consoles, Wii was favored with consumers after Nintendo began to sale it, because we could use the motion controller to control the games. However, the gap of the quantities of new generation video game consoles was narrowed by the SONY and Microsoft after they started to offer motion controllers, the Playstation Move for PS3 and Kinect for XBOX 360. Therefore, understandingthe factors that affect the intention of X and Y generation consumers, the main consuming group of video game consoles, to purchase new generation video game consoles is the important thing for corporations. We add perceived playfulness and portraits of the new generation into Technology Acceptance Model (TAM) and modify TAM to discuss the factors to affect the intention of X and Y generation consumers to purchase new generation video consoles. The total research effective tests are 202 copies. The conclusions of this study are presented as follows: 1. X generation consumers pay more attention to perceive usefulness, and Y generation consumers pay more attention to perceived playfulness. 2. Variables that affect X and Y generation consumers most are perceived usefulness, perceived playfulness, portraits of video game consoles and intention of use. 3. TAM is confirmed that it¡¦s suitable for the study on video game consoles.

This diploma thesis concerns Service-Oriented Architecture and possibilities of using framework NGOSS (New Generation Operations Systems and Software) by its adoption to organization. Diploma thesis is divided into four main parts. The first three parts are theoretical and are the foundation for the last practical part of diploma thesis. The first part is devoted to enterprise architecture and to their importance for a big company. The second part of the diploma thesis is devoted to framework, to their principles and importance in connection with enterprise architecture. In first chapters of this part is devoted to description of framework generally, while the last parts contain the description of particular framework for telecommunication industry named NGOSS. I describe its main characteristics and its main parts with emphasis on its part concerning architecture of information system named TNA (Technology Neutral Architecture). This TNA description also contains description of NGOSS contract, which is very important for practical part of diploma thesis. The third and the last theoretical part is concerned with service oriented architecture and its main architectural elements -- services. In the last and practical part of diploma thesis, I am trying to design NGOSS contract for the chosen SOA service and demonstrate its importance for SOA adoption. The end of the practical part contains conclusion on possibilities and benefits of NGOSS framework by SOA adoption.

Bases moléculaires de la variation clonale chez la vigne (Vitis vinifera L.) : approche pangénomique / Molecular bases of clonal variation from grape (Vitis Vinifera L.)

Carrier, Grégory 13 December 2011 (has links)
L'exploitation de la variation clonale est une des voies d'amélioration utilisée chez un grand nombre de plantes d'intérêts agronomiques telles que la pomme de terre, le café et la vigne. En effet, après plusieurs cycles de reproduction végétative, des caractéristiques agronomiques stables apparaissent donnant naissance à une diversité phénotypique remarquable, appelée « diversité clonale ». Chez la vigne, cette diversité clonale est d'une importance majeure pour les viticulteurs puisqu'elle permet une amélioration variétale sans changer d'identité de cépage en conformité avec la réglementation fixée par Appellations d'Origine Protégée. L'hypothèse la plus parcimonieuse expliquant cette diversité phénotypique clonale est l'accumulation de mutations somatiques au cours des cycles de reproduction végétative. L'objectif de cette thèse a été de dresser un panorama le plus exhaustif possible des différents polymorphismes moléculaires entre les génomes de plusieurs clones. Dans un premier temps trois clones de Pinot ont été séquencés par la technique 454 GS-FLX puis dans un second temps 11 clones de quatre cépages ont été séquencés la technique Illumina HiSeq 2000. Afin d'analyser la grande quantité de données obtenues, nous avons construit un pipeline d'analyse (Bacchus pipeline) permettant d'identifier tous les types de polymorphismes moléculaires entre les différents génomes.Nos résultats permettent, pour la première fois un inventaire exhaustif des polymorphismes moléculaires dans un contexte multiplication végétatif. L'ensemble des mutations polymorphes entre deux clones a pu être identifié, SNPs, indels (2,5 SNPs et 11,5 indels par Mb en moyenne) ainsi que des variations d'ordre structural (larges insertions ou délétions) représentant la classe la plus fréquente (129 évènements par Mb entre deux clones en moyenne). Afin d'évaluer le polymorphisme d'insertion généré par ces éléments nous en avons étudié quatre par une approche S-SAP sur plusieurs niveaux de diversité (inter-espèces, inter-cépages, inter-clones et entre plusieurs tissus d'un même individu). L'analyse phylogénétique au niveau des espèces est conforme à celle réalisée avec d'autres types de marqueurs moléculaires (SSR, SNP). Cependant, une forte instabilité de ces insertions a été confirmée entre les clones et entre les tissus d'un même d'individu. L'identification des clones par une méthodologie moléculaire serait d'une grande importance pour la filère. Pour cet objectif, nos résultats indiquent que les mutations de types SNP et petits indels qui sont certes moins fréquentes que les variations structurales mais qui sont plus stables semblent plus pertinentes pour la mise en place d'une méthodologie d'identification des clones / Clonal variation is considered as an effective contribution to breeding programs of vegetatively propagated species with major agronomical interest such as banana, potato, coffee and grape. Indeed, after several propagation cycles, stable and heritable phenotypic variations appear giving rise to a phenotypic variation termed “clonal diversity”. This clonal diversity is very important for wine-growers because it allows preserving cultivars identity in the strict respect of Appellation (A.O.P) wines specifications The most parsimonious hypothesis explaining clonal phenotypic diversity is the accumulation of somatic mutations. The objective of my thesis was to provide a broad description of molecular polymorphisms in the context of vegetative propagation. Three clones were first sequenced by 454 GS-FLX technology and eleven clones were then sequenced with Illumina Hiseq2000 technique. To analyse the high quantity of data obtained, we built a pipeline (Bacchus pipeline) allowing the identification of all existing molecular polymorphisms between different genomes.All polymorphism types were observed: indels and SNPs which have a low polymorphism frequency (2.5 SNPs and 11.5 indels per Mb between two clones in average) and structural variations (large insertions or deletions) which have a high polymorphism frequency (129 per Mb between two clones in average) but are unstable. To evaluate stability and polymorphism level of these transposable elements, we have studied 4 elements using S-SAP method at different diversity levels (inter-species, inter-cultivars, inter-clones and between organs/tissues of a single individual). Our interspecific phylogenetic analysis is similar to other phylogenies performed with SSR or SNPs markers. However, we confirm the high instability of these elements between clones and between tissues in single individuals.Clone identification through molecular methods would be of high significance for the wine industry. SNP or small indels mutations are less frequent but more stable than structural variation and could be used for accurate clone identification.
