Abstract:

Web services are a new breed of Web application. They are self-contained, self-describing, modular applications that can be published, located, and invoked across the Web [154] Web services are a promising technology for ad hoc machine to machine interaction across application, enterprise and web boundaries. Self describing web services is a catchy phrase but it should mean more than having an interface description written in XML syntax. This research is motivated by the vision of web services in the future as loosely coupled applications operating on different platforms inter-operating without prior agreements in place and without direct human intervention at runtime. The main obstacle to advancing the vision of ad hoc runtime interaction is complexity. The complexity of ad hoc interaction for web services is related to 1) the information the service requires and provides and the nuances of the domain or context the service operates on and in. 2) The specific nature of the operations the service provides and the constraints related to those operations and 3) the necessary ordering of operations to achieve the desired result. There are three problems that must be addressed before the vision for web services can become a reality. These problems are aligned with the three aspects of service complexity identified above. The three inter-related elements of this research address each of these problems. The first part of the research deals with what web services "talk" about and how the data required or provided by services can be described to enable mutual understanding. An extension to traditional conceptual models, called outsourced type descriptions, allows the description of shared data in terms of publicly available information, including standards, specifications, ontologies and definitions from dictionaries and thesauri. The second part is concerned with describing why services interact and the capabilities (actions or information) services can provide. A structured format for the description, advertisement and discovery of services based on what they actually do is presented. The structured format is based on previous work in the description of actions and the context in which they are performed. The last part of the research addresses how previously unknown services can talk to one another to supply and use the advertised capabilities. Interaction is based on providers having "plans" for the delivery of capabilities. The flow of interaction is directed by the service providers' data requirements and is responsive to the resources of the client. A small language for information gathering based on well known interaction primitives is defined. An example implementation of a capability plan interpreter demonstrates how messages are generated, managed and interpreted at runtime in order to satisfy the client's goals.

Abstract:

Les travaux de recherche menés autour de la description de services Web utilisent de plus en plus des modèles sémantiques pour fournir une représentation interprétable automatiquement. Toutefois, nous avons décelé des lacunes dans les approches sémantiques actuelles qui engendrent ambiguïté et non pertinence au niveau de l'appariement et de la découverte de services Web. Pour remédier à ces lacunes nous proposons des contributions à la description et à la découverte de services Web sémantiques. En ce qui concerne la description de services, nous avons défini un langage basé sur une recommandation W3C. En plus d'une annotation métier sémantique des éléments d'un service, notre principale contribution à la description sémantique consiste à spécifier la nature de ces annotations en utilisant une ontologie technique que nous avons définie. Cette ontologie met en relation plusieurs concepts sémantiques de services Web que nous avons identifiés dans des approches existantes et intègrera d'autres concepts qu'on définira ultérieurement sans pour autant modifier notre langage de description ou nos techniques d'appariement associées. Nous avons également défini un algorithme d'appariement entre une requête de service et les descriptions des services publiés. Cet algorithme se base sur un appariement entre éléments d'une requête et un service publié et trois techniques d'agrégation des résultats d'appariements élémentaires. L'algorithme tire avantage de la description sémantique que nous avons définie. Il a été mis en œuvre dans un annuaire de services Web sémantiques et a été également comparé aux algorithmes de référence. Les expérimentations montrent clairement l'efficacité de notre approche en termes de temps de réponse et de précision

Abstract:

Le but de cette thèse est de dégager un cadre sémantique formel approprié supportant l'interopérabilité dedifférents formalismes déjà utilisés pour décrire et déployer un service Web. En d’autres termes, nouscontribuons au développement d’un formalisme mathématique rigoureux permettant de décrire un service Webcomplexe susceptible de changer pendant l’exécution et de coordonner avec les autres services de façonadaptative. Pour atteindre cet objectif, les étapes de description, de sélection et de composition ont constitué lestrois majeures problématiques étudiées dans cette thèse.Pour ce faire, nous avons proposé dans un premier temps, à travers l’utilisation du cadre sémantique formel K lelangage K-WSDL; un langage de description de services Web doté d’une sémantique opérationnelle en terme derègles de réécriture qui peut être exécutable et analysable sous Maude. Nous avons introduit, dans un secondtemps, l’approche WS-Sim basée sur la théorie des catégories qui évalue l’équivalence comportementale entreservices en représentant chaque service par une catégorie et en établissant des liens formels (foncteur) entre elles.Enfin, nous avons présenté le modèle RMop-ECATNet (Refined Meta Open ECATNet ) : un modèle dédié à laspécification formelle de la composition des services Web et fruit du raffinement du modèle Mop-ECATNetproposé par [LB14]. Nous avons étendu et enrichi ce dernier aux trois niveaux : structurel, comportemental etimplémentation
The aim of this thesis is to provide a suitable formal semantic framework that supports interoperability ofdifferent formalisms already used to describe and deploy a Web service. In other words, we contribute to thedevelopment of a rigorous mathematical formalism to describe a complex Web service that may change duringexecution and coordinate with other services adaptively. To achieve this goal, the steps of description, selectionand composition constitute the three major issues studied in this thesis.We proposed so, initially, through the use of the K semantic framework the K-WSDL : a Web servicesdescription language endowed with an operational semantics in terms of rewriting rules which can be executedand analyzed in Maude. We introduced, in a second step, WS-Sim, a new approach based on the category theorywhich evaluates the behavioral equivalence between services by representing each service by a category and byestablishing formal links (functor) between them. Finally, we present RMop-ECATNet (Refined Meta OpenECATNet): a formal model for the specification of services composition. product of the refinement of the Mop-ECATNets model, introduced initially by [LB14]. We extended and enriched this model at three distinct levels:at the structural, behavioural level and implementation levels

Abstract:

L'intelligence ambiante est un domaine hautement interdisciplinaire et implique de nombreux domaines de recherche. C'est pourquoi les avancées dans ce domaine sont conditionnées par l'interaction et l'intégration entre ces nombreuses disciplines. Ce manuscrit s'intéresse à la problématique de capitalisation des travaux existants, ainsi qu'à l'intégration dynamique de logiciels et d'appareils développés indépendamment les uns des autres. Nous proposons une intergiciel à services et une interface graphique utilisables et extensibles par les différents spécialistes. En étendant les approches à services et les principes du web sémantique, nous proposons une méthode de conception facilitant l'intégration dynamique et la composition de services. Cette méthode se base sur le concept nouveau d'usines à services : un service capable d'en instancier d'autres sur demande. Nous proposons aussi un langage de description pour ce langage.

Abstract:

La technologie des services Web est considérée commme une solution robuste et évolutive aux problèmes actuels d'intégration de données dans des architectures dont la complexité ne cesse d'augmenter. La structure des données (avec XML) et la façon dont elles sont échangées entre les différents services , (à l'aide de SOAP par le biais du protocole HTTP) ont été standardisées, rendant l'implémentation des services totalement indépendante de la manière dont ils communiquent. Le vrai potentiel de cette architecture ne sera atteint que quand une automatisation des processus de découverte et de composition des services sera possible, ce qui n'est actuellement pas le cas en raison de l'impossibilité pour les machines d'interpréter les données qu'elles échangent. Les services Web sémantiques visent à supprimer cette limitation en ajoutant une dimension sémantique à la description des services. Le travail présenté dans cette thèse porte sur un cadre visant la description, la découverte et la composition dynamique et sécurisée de services Web sémantiques, à l'aide d'un langage de descritpion hybride reposant sur une partie structurelle basée sur la logique de description, décrivant les relations entre les descripteurs des services, et sur une partie relationnelle dans laquelle des règles permettent d'exprimer des contraintes sur les réponses potentiellement retournées par les services décrits. La découverte de services ainsi décrits répondant à une requëte donnée se fait en deux temps : le premier en raisonnant sur la partie structurelle de la description, et le deuxième sur la partie relationnelle, nous permettant alors de supprimer de l'espace des solutions les services dont on sait grâce aux contraintes qu'ils ne peuvent pas fournir de réponses à la requête soumise. Enfin, nous présentons un moyen de composer dynamiquement des services de manière sécurisée, en utilisant une approche basée sur la notion de confiance.

Abstract:

Linklets are location-independent web services, which consume and produce Linked Data resources. These resources form a web of data - the semantic web - that is an abstraction of the web 2.0. However, enterprises are reluctant to provide valuable Linked Data resources due to missing financial stimuli. Operations are not representable in the semantic web. Linklets aim to solve both problems. Previous work developed a prototype. The goal of this thesis is to enhance it by a component model, a formal description and a permission model. A business model has to be developed. This thesis follows a bottom-up approach. The formalization of the Linklet concept creates a foundation. Then, an improved architecture and its reference implementation are studied. It is evaluated by tests, show cases and economic considerations. The resulting component system is based on web-service component systems, while a sandbox concept is the core of the permission model. The formal description shows limits of OWLs open world assumption. A platform leader strategy is the foundation for the business model. In conclusion, the advantages of the Linklet concept provide a way to enhance and monetize the value of the semantic web. Further research is required; the practical use has to be considered.

Abstract:

With the evolution of the World Wide Web and the advancement of the electronic world, the diversity of available services is increasing rapidly.This raises new demands for the efficient discovery and location of heterogeneous services and resources in dynamically changing environments. The traditional approaches for service discovery such as UDDI, Salutation, SLP etc. characterise the services by using predefined service categories and fixed attribute value pairs and the matching techniques in these approaches are limited to syntactic comparisons based on attributes or interfaces. More recently with the popularity of Semantic Web technologies, there has been an increased interest in the application of reasoning mechanisms to support discovery and matching. These approaches provide important directions in overcoming the limitations present in the traditional approaches to service discovery. However, these still have limitations and have overlooked issues that need to be addressed; particularly these approaches do not have an effective ranking criterion to facilitate the ordering of the potential matches, according to their suitability to satisfy the request under concern. This thesis presents a semantic matching framework to facilitate effective discovery of device based services in pervasive environments. This offers a ranking mechanism that will order the available services in the order of their suitability and also considers priorities placed on individual requirements in a request during the matching process. The proposed approach has been implemented in a pervasive scenario for matching device-based services. The Device Ontology which has been developed as part of this research, has been used to describe the devices and their services. The retrieval effectiveness of this semantic matching approach has been formally investigated through the use of human participant studies and the experimental results have indicated that the results correlate well with human perception. The performance of the solution has also been evaluated, to explore the effects of employing reasoning mechanisms on the efficiency of the matching process. Specifically the scalability of the solution has been investigated with respect to the request size and the number of advertisements involved in matching.

Abstract:

Cette thèse de Doctorat s'articule autour des services web dont le processus métier est décrit en utilisant un langage de description comportementale tel que XLANG ou BPEL. Nous fournissons une méthode, des algorithmes et leurs implémentations permettant de modéliser sous forme de systèmes de transitions temporisées (TIOTS en temps discret et automates temporisés en temps dense) le comportement de ces services web. Pour cela, nous avons fixé une sémantique à l'aide des algèbres de processus temporisés nous permettant de décrire formellement le comportement, en terme d'actions, d'exceptions et d'évènements temporels, de chaque opérateur de ces langages de descriptions comportementales. Ces descriptions sont alors directement traduisibles dans le système de transitions temporisées choisi. Par la suite, grâce à notre relation d'interaction, nous pouvons détecter la nonambiguïté d'un tel service ainsi modélisé, assurant l'interaction possible avec un client adapté dont nous fournissons alors le modèle. Nous avons également étendu notre approche à la possibilité de vérifier l'interaction des différents partenaires d'une chorégraphe, permettant ainsi de détecter une possible ambiguïté dans cette interaction
This PhD thesis is about web services, in which business process is described by using a behaviour description language, such as XLANG or BPEL. We give a method, algorithms and their implementations enable us to modelling in timed transition systems (TIOTS in discrete time and timed automaton in dense time) the behaviour of these web services. We give semantics with algebra of timed processes, enabling us to describe formally the behaviour, concerning actions, exceptions and timed events, ofeach operator of these behaviour description languages. These descriptions are directly translating in the given timed transition systems. In the next, with our interaction relation, we can detect the non ambiguity of this service, providing possible interaction with an adapted client that we produce the model. We extend our approach to the possibility to verify the interaction of different partners of a given choreography, enable us to detect a possible ambiguity in this interaction

Abstract:

Le développement orienté-service et le cloud computing offrent beaucoup d'opportunités au développement et au déploiement d'applications. En effet, le développement orienté-service permet de composer des fonctionnalités issues de services distribués, développés par différentes organisations. D'un autre côté, le cloud computing permet de provisionner des environnements évolutifs (en fonction du besoin en ressources) de développement et de déploiement, à la demande. Dans ce travail de recherche, nous proposons et décrivons une méthode de provisonnement automatique d'applications métier, orientées-service sur le cloud. Nous avons appelé cette méthode MADONA (Method for AutomateD prOvisioning of service-oriented busiNess Applications). MADONA couvre le cycle de vie de provisionnement d'applications et est basée sur un orchestrateur de services pour la gestion de la configuration, du déploiement, et de la composition de services métier.Dans ce travail, nous visons à réduire les connaissances techniques nécessaires au provisionnement d'applications métier. Pour ce faire, nous apportons trois contributions majeures. Premièrement, l'automatisation de ce provisionnement. En effet, les phases de MADONA sont complètement automatisées. L'utilisateur n'intervient que pour exprimer son besoin et pour utiliser l'application métier automatiquement générée (par la composition de services métier) et déployée sur une IaaS présélectionnée. Deuxièmement, l'enrichissement de la description des services par des concepts liés aux relations d'un service. En effet, les langages de description de services décrivent le plus souvent ces derniers comme des entités isolées et ne considèrent pas les relations entre services. Nous avons défini dans ce travail les relations de composition qui décrivent pour chaque service métier les services nécessaires à son bon fonctionnement, et les services avec lesquels il peut être composé.Troisièmement, nous permettons à l'utilisateur d'exprimer son besoin à un haut niveau d'abstraction des détails techniques de composition et de déploiement. Nous avons pour cela défini un vocabulaire pour formaliser ces besoins fonctionnels (en termes de mots clés décrivant les fonctionnalités désirées, ou de noms de services désirés) et non fonctionnels (en termes de coût, de préférences de déploiement (ex : localisation de déploiement), et de qualité de service). La méthode a été prototypée et testée suivant plusieurs scénarios montrant sa faisabilité
Service-oriented computing and cloud computing offer many opportunities for developing and deploying applications. In fact, service-oriented computing allows to compose several functionalities from distributed services developed by different organizations. On the other hand, cloud computing allows to provision on demand scalable development and deployment environments. In this resarch work, we propose and describe a Method for AutomateD prOvisioning of service-oriented cloud busiNess Applications (MADONA). The method covers the whole application’s lifecycle and is based on cloud orchestration tools that manage the deployment and dependencies of supplied components. This research work aims to reduce the necessary technical knowledge for provisioning service-oriented cloud applications. To this end, we bring three major contributions. Firstly, we automatise the whole application provisioning. In fact, MADONA phases are fully automated. The user intervenes only in requirement elicitation and when the application is deployed and ready to use. The business application is automatically generated (by composing business services) and deployed in an automatically preselected IaaS. Secondly, we enrich the description of services by integrating concepts describing services’ interactions. In fact, service description languages usually describe services as isolated components and does not consider the interactions between services. We define in this work, composition interactions which describe for each business service, its necessary services and the services with which it can be composed. Thirdly, we allow the user to express her requirements abstracting composition and deployment technical details. To this end, we defined a RequIrement VocAbuLary (RIVAL) to formalize user’s functional (in terms of keywords describing the desired functionalities, or names of desired services) and non-functional requirements (in terms of cost, deployment preferences (ex. preferred location), and quality of service). The method has been implemented and tested showing its faisability

Abstract:

This thesis addresses the question of what would be a domain independent taxonomy that is capable of representing the non-functional properties of conventional, electronic and web services. We cover all forms of services, as we prefer not to make any distinction between the three forms. Conventional service descriptions, such as newspaper advertisements, are rich in detail, and it is this richness that we wish to make available to electronic and web service descriptions. In a conventional service context, when we ask a service provider for details, perhaps by phoning the service provider, we are seeking ways to assist with decision making. It is this same decision making or reasoning that we wish to be available to electronic services. Historically, services have always been distinguished according to some criteria of a service requestor. Examples are price, payment alternatives, availability and security. We are motivated to ensure that the criteria used to evaluate conventional services are also available for electronic and web services. We believe that the ability to richly and accurately describe services has significant applicability in the areas of electronic service discovery, dynamic service composition, service comparison, service optimisation, and service management. In particular, the increased level of descriptive depth will also facilitate more thorough decision-making by a service requestor. Whilst we acknowledge the importance of service functionality, this thesis is primarily concerned with the non-functional properties of services. A service is not a function alone. It is a function performed on your behalf at a cost. And the cost is not just some monetary price; it is a whole collection of limitations. This thesis is all about these. We believe that to accurately represent any service, a description requires information relating to both the functionality and the associated constraints. We consider these constraints over the functionality of the service to be non-functional properties. We believe that a service description is only complete once the non-functional aspects are also expressed. We undertook a significant analysis of services from numerous domains. From our analysis we compiled the non-functional properties into a series of 80 conceptual models that we have categorised according to availability (both temporal and locative), payment, price, discounts, obligations, rights, penalties, trust, security, and quality. Our motivation is to provide a theoretical basis for automated service discovery, comparison, selection, and substitution. The need to describe a service is analogous with labelling for goods or products. Product labelling occurs for the safety and benefit of purchasers. Why is the same labelling not afforded for the benefit of service requestors?

Abstract:

Les sources de données multimédias provenant de divers domaines (médical, tourisme, commerce, art et culture, etc.) sont devenues incontournables sur le web. L’accès à ces sources multimédias dans les systèmes distribués pose de nouveaux problèmes en raison de nombreux paramètres : volumétrie, diversité des interfaces, format de représentation, localisation, etc. En outre, l’exigence de plus en plus forte des utilisateurs et des applications à vouloir intégrer la sémantique dans la recherche d’information pose de nouvelles questions à résoudre. Pour prendre en compte cette nouvelle complexité, nous nous intéressons dans notre travail de recherche aux solutions d’intégration de données basées sur les services web. Dans cette thèse, nous proposons une approche orientée service pour la recherche sémantique de contenus multimédia. Nous avons appelé cette approche SeSaM (Semantic Search of Multimedia content). SeSaM repose sur la définition d’un nouveau type de services accédant aux contenus multimédias, qui est les services MaaS (Multimedia as a Services). Elle est basée sur un processus en deux phases : description et découverte des services MaaS. En ce qui concerne la description de services MaaS, nous avons défini le langage SA4MaaS (Semantic Annotation for MaaS services), qui est une extension de SAWSDL (recommandation W3C). L’idée principale de ce langage est l’intégration, en plus de la sémantique métier, de la sémantique de l’information multimédia dans la description des services MaaS. En ce qui concerne la découverte de services MaaS, nous avons proposé un nouveau matchmaker MaaS-MX (MaaS services Matchmaker) adapté au modèle de description des MaaS. MaaS-MX est composé de deux étapes primordiales : appariement métier et appariement multimédia. L’appariement métier consiste à comparer la description métier des services et de la requête, tandis que l’appariement multimédia compare la description multimédia des services et de la requête. L’approche a été prototypée et évaluée dans deux domaines différents : médical et tourisme. Les résultats indiquent que l’utilisation de l’appariement métier et l’appariement multimédia a considérablement amélioré les performances des systèmes de recherche de données multimédias
Multimedia data sources from various fields (medical, tourism, trade, art and culture, etc.) became essential on the web. Accessing to multimedia data in distributed systems poses new challenges due to many system parameters: volume, diversity of interfaces, representation format, location, etc. In addition, the growing needs of users and applications to incorporate semantics in the information retrieval pose new issues. To take into account this new complexity, we are interested in our research of data integration solutions based on web services. In this thesis, we propose an approach-oriented service for the semantic search of multimedia content. We called this approach SeSaM (Semantic Search of Multimedia content). SeSaM is based on the definition of a new pattern of services to access multimedia content, which is the MaaS services (Multimedia as a Services). It is based on a two-phase process: description and discovery of MaaS services. As for the MaaS services description, we have defined the SA4MaaS language (Semantic Annotation for MaaS services), which is an extension of SAWSDL (W3C recommendation). The main idea of this language is the integration, in addition to business domain semantic, of multimedia information semantics in the MaaS services description. As for the MaaS service discovery, we have proposed a new matchmaker MaaS-MX (MaaS services Matchmaker) adapted to the MaaS services description model. MaaS-MX is composed of two essential steps: domain matching and multimedia matching. Domain matching consists in comparing the business domain description of MaaS services and the query, whereas multimedia matching compares the multimedia description of MaaS services and the query. The approach has been implemented and evaluated in two different domains: medical and tourism. The results indicate that using both domain and multimedia matching considerably improves the performance of multimedia data retrieving systems

Abstract:

Professional literature in the past five years regarding the care and treatment of deinstitutionalized chronic mentally ill (CMI) persons has presented growing concerns that services for some CMI persons are inadequate or nonexistent. A number of previous authors have suggested that there may be a consistent, as opposed to a random, bias in the traditional mental health service delivery system whose services are contingent upon client characteristics that, in the very least, assume foresight, independence, initiative, and consistency. Lacking these qualities, clients may not seek services to which they are entitled or they may be frustrated in maintaining those services. This study provides a description of a CMI population (n = 142) that received outreach services from a small county psychiatric hospital. These clients were selected because they were evaluated as severely disturbed, potentially impulsive, and had a history of not following through with traditional mental health services, i.e., they did not make or keep prescribed appointments for therapy or education. This group served as a model against which to compare characteristics of the traditionally engaged clients. Previous authors as well as this study found that the dropout populations were younger, less compliant with prescribed anti-psychotic medication, engaged in more alcohol and drug use, were more likely to live independently and to be rehospitalized with greater frequency. Increased hospitalization also correlated with less functional independent living skills. In other reported research several variables were found to discriminate the younger CMI. This study could only confirm an increase in substance abuse although several confounding factors are discussed. Finally, the outreach program itself was examined, some services were quantified, and some were related to specific client characteristics. For instance, 40 percent of this CMI population was primarily reliant on their outreach worker for all transportation beyond walkable distances; and those clients receiving the most number of outpatient visits were those rated most rejecting of services and those with the poorest independent living skills. The treatment population was found to have reduced their total number of admissions and days hospitalized during the two-year period of investigation.

Dans cette recherche, nous abordons le problème de le recherche de services qui répondent à des besoins des utilisateurs exprimés sous forme de requête en texte libre. Notre objectif est de résoudre les problèmes qui affectent l'efficacité des modèles de recherche d'information existant lorsqu'ils sont appliqués à la recherche de services dans un corpus rassemblant des descriptions standard de ces services. Ces problèmes sont issus du fait que les descriptions des services sont brèves. En effet, les fournisseurs de services n'utilisent que quelques termes pour décrire les services souhaités. Ainsi, lorsque ces descriptions sont différentes des phrases dans les requêtes ce qui diminue l'efficacité des modèles classiques qui dépendent de traits observables au lieu de traits sémantiques latents du texte. Nous avons adapté une famille de modèles de recherche d'information (IR) dans le but de contribuer à accroître l'efficacité acquise avec les modèles existant concernant la découverte de services. En outre, nous avons mené des expériences systématiques afin de comparer notre famille de modèles IR avec ceux de l'état de l'art portant sur la découverte de service. Des résultats des expériences, nous concluons que notre modèle basé sur l'extension des requêtes via un thésaurus co-occurrence est plus efficace en terme des mesures classiques utilisées en IR que tous les modèles étudiés dans cette recherche. Par conséquent, nous avons mis en place ce modèle dans S3niffer, qui est un moteur de recherche de service basé sur leur description standard
In this research, we address the problem of retrieving services which fulfil users' need expressed in query in free text. Our goal is to cope the term mismatch problems which affect the effectiveness of service retrieval models applied in prior re- search on text descriptions-based service retrieval models. These problems are caused due to service descriptions are brief. Service providers use few terms to describe desired services, thereby, when these descriptions are different to the sentences in queries, term mismatch problems decrease the effectiveness in classical models which depend on the observable text features instead of the latent semantic features of the text. We have applied a family of Information Retrieval (IR) models for the purpose of contributing to increase the effectiveness acquired with the models applied in prior research on service retrieval. Besides, we have conducted systematic experiments to compare our family of IR models with those used in the state-of-the-art in service discovery. From the outcomes of the experiments, we conclude that our model based on query expansion via a co-occurrence thesaurus outperforms the effectiveness of all the models studied in this research. Therefore, we have implemented this model in S3niffer, which is a text description-based service search engine

Abstract:

Dans un contexte où les outils numériques et le WEB permettent la diffusion et le partage massif de ressources, le défi actuel est de trouver la bonne ressource au bon moment. Pour les ressources d’enseignement, les standards de description actuels (LOM ou ScoLOMFr par exemple) ne permettent pas une description des dimensions didactiques d’une ressource. Notre thèse est une contribution pour combler ce manque, en nous situant dans le domaine de environnements informatiques pour l’apprentissage humain (EIAH). Nous nous sommes particulièrement intéressé à la description de ressources de type « énoncé avec tâche prescrite » (ETP). Nous nous sommes placé dans le cadre de la théorie anthropologique du didactique (TAD) et avons en particulier exploité la formalisation de l’approche praxéologique proposée par le cadre T4TEL. Nous proposons quatre résultats principaux. Le premier est un modèle de description didactique de ressources (M2DR) de type ETP. Il permet la description d’un ETP sur la base de critères didactiques et de déterminer son adéquation avec un curriculum. Ce modèle est construit à partir de l’exploitation d’un modèle praxéologique de référence (MPR). Le deuxième résultat est la modélisation d’intentions didactiques, utilisées pour pouvoir chercher des ETP décrits à l’aide du modèle M2DR. Le troisième résultat est un enrichissement du cadre T4TEL, en définissant une modélisation de la tâche et en introduisant la notion de type de tâches optimum. Le quatrième résultat est la définition d’un processus de construction d’une représentation ontologique d’un MPR décrit dans T4TEL à l’aide de générateurs de types de tâches. Ce processus permet une utilisation du modèle dans un cadre informatisé. Il a été appliqué à différents MPR, dans les domaines de l’algèbre élémentaire et de la numération. Ceci a permis l’utilisation du modèle M2DR pour décrire différents ETP
In a context where digital tools and the WEB allow for the diffusion and massive sharing of resources, the current challenge is to find the right resource at the right time. Current description standards (e. g. LOM or ScoLOMFr) do not allow the description of the didactic dimensions of a learning object. Our thesis is a contribution to fill this gap from the Technology-Enhanced Learning (TEL) field point of view. We were particularly interested in the description of mathematics exercises. We conducted our work within the Anthropological Theory of Didactics (ATD) framework. More specifically, we have exploited the formalization of the praxeological approach proposed by the T4TEL framework. Our findings and propositions are four-fold. First, we proposed a didactic resource description model (M2DR) that allows the description of a mathematics exercises based on didactic criteria and determines its suitability for a curriculum. This model is based on the use of a reference epistemological model (REM). The second result is the modeling of didactic intentions, used for searching for mathematics exercises described with the M2DR model. The third result is an enhancement of the T4TEL framework defining a task model and introducing the notion of optimal types of tasks. The fourth result is the definition of a process for implementing an ontological representation of a REM described in T4TEL using types of tasks generators. This process allows the model to be used in a computerized environment. It has been applied to different REMs in the fields of elementary algebra and numeracy. That fostered the use of the M2DR model to describe different mathematics exercises

La présente recherche a comme objectifs de décrire et comparer (milieu familial, placement) les services reçus par les parents selon que l'enfant ait été maintenu en milieu familial ou placé en milieu substitut et d'évaluer l'efficacité des services externes et du placement pour résorber les problèmes des parents. La présente étude utilise un devis quasi expérimental avec pré-test et post-test et a été menée auprès de 70 parents et enfants (âgés entre 6 et 11 ans) desservis par les Centres jeunesse du Québec. Le suivi de ces familles sur 12 mois a permis de les diviser en deux groupes selon que l'enfant ait été maintenu en milieu familial (n = 42) ou qu'il ait été placé en cours d'année (n = 28). Les services reçus par les parents durant l'année et, plus particulièrement, les cibles d'interventions, la fréquence de ces interventions et la référence à des services extra-familiaux ont été évalués à l'aide d'un questionnaire d'entrevue téléphonique sur les services reçus en provenance des Centres jeunesse."--Résumé abrégé par UMI

Abstract:

Ces dernières années ont témoigné du succès du projet Linked Open Data (LOD) et de la croissance du nombre de sources de données sémantiques disponibles sur le web. Cependant, il y a encore beaucoup de données qui ne sont pas encore mises à disposition dans le LOD telles que les données sur demande, les données de capteurs etc. Elles sont néanmoins fournies par des API des services Web. L'intégration de ces données au LOD ou dans des applications de mashups apporterait une forte valeur ajoutée. Cependant, chercher de tels services avec les outils de découverte de services existants nécessite une connaissance préalable des répertoires de services ainsi que des ontologies utilisées pour les décrire.Dans cette thèse, nous proposons de nouvelles approches et des cadres logiciels pour la recherche de services web sémantiques avec une perspective d'intégration de données. Premièrement, nous introduisons LIDSEARCH, un cadre applicatif piloté par SPARQL pour chercher des données et des services web sémantiques.De plus, nous proposons une approche pour enrichir les descriptions sémantiques de services web en décrivant les relations ontologiques entre leurs entrées et leurs sorties afin de faciliter l'automatisation de la découverte et de la composition de services. Afin d'atteindre ce but, nous utilisons des techniques de traitement automatique de la langue et d'appariement de textes basées sur le deep-learning pour mieux comprendre les descriptions des services.Nous validons notre travail avec des preuves de concept et utilisons les services et les ontologies d'OWLS-TC pour évaluer nos approches proposées de sélection et d'enrichissement
The last years witnessed the success of the Linked Open Data (LOD) project as well as a significantly growing amount of semantic data sources available on the web. However, there are still a lot of data not being published as fully materialized knowledge bases like as sensor data, dynamic data, data with limited access patterns, etc. Such data is in general available through web APIs or web services. Integrating such data to the LOD or in mashups would have a significant added value. However, discovering such services requires a lot of efforts from developers and a good knowledge of the existing service repositories that the current service discovery systems do not efficiently overcome.In this thesis, we propose novel approaches and frameworks to search for semantic web services from a data integration perspective. Firstly, we introduce LIDSEARCH, a SPARQL-driven framework to search for linked data and semantic web services. Moreover, we propose an approach to enrich semantic service descriptions with Input-Output relations from ontologies to facilitate the automation of service discovery and composition. To achieve such a purpose, we apply natural language processing techniques and deep-learning-based text similarity techniques to leverage I/O relations from text to ontologies.We validate our work with proof-of-concept frameworks and use OWLS-TC as a dataset for conducting our experiments on service search and enrichment

Abstract:

Le principe d'élasticité est d'assurer que juste les ressources nécessaires sont provisionnées pour préserver le bon fonctionnement des services Cloud. La propriété d'élasticité permet d'éviter la sous-utilisation et la sur-utilisation des ressources. La propriété d'élasticité a attiré beaucoup d'attention ces dernières années comme une tâche pivot qui permet d'assurer un bon compromis entre les QdS désirées et les coûts opérationnels des AbSs. Toutefois, le contrôle d'élasticité des AbSs et la définition des stratégies d'élasticité non-triviales sont encore des tâches difficiles à réaliser. Une stratégie d'élasticité est utilisée pour gérer l'élasticité en décidant des trois éléments essentiels: 'quand', 'où' et 'comment' utiliser les mécanismes d'élasticité (par exemple, les opérations de duplication/consolidation de services) qui permettent d'assurer les objectifs de QdS avec une consommation optimisée des ressources. La complexité de définition de stratégies d'élasticité augmente avec les métriques de QdS considérées. La difficulté de cette tâche est de plus accentuée avec l'absence d'un langage unifiée pour exprimer ces stratégies. Notre travail de thèse vise à remédier aux limites des approches existantes pour la gestion des stratégies d'élasticité. Il consiste à développer un langage pour décrire différents types des stratégies d'élasticité d'une façon unifiée. Nous définissons un modèle formel qui cadre l'ensemble de métriques à considérer, définit les opérations d'élasticité à appliquer et spécifie les lois d'émission de requêtes. Ce modèle servira aussi pour appliquer et valider les stratégies spécifiées. Nous travaillons en plus sur l'alignement des contrats de qualités de services (Service Level Agreement) avec les stratégies d'élasticité
Elasticity is the ability of a system to be adjustable to workload change by allocating and releasing as many resources as needed while ensuring the agreed QoS. It has played a pivotal role in many research works for ensuring QoS. Therefore, Elasticity management is witnessing a lot of attention from IT community as a pivotal issue for finding the right tradeoffs between QoS levels and operational costs by working on developing novel methods and mechanisms. However, controlling business process elasticity and defining non-trivial elasticity strategies are challenging issues. Elasticity strategies are policies that are used to manage elasticity by deciding when, where and how to use elasticity mechanisms (e.g, adding or removing resources). Many strategies can be defined to ensure applications elasticity. The abundance of possible strategies requires their evaluation and validation in order to guarantee their effectiveness before using them in real Cloud environments. Our thesis work aims to overcome the limitations of the existing approaches for elasticity strategies management. It consists in developing a configurable Domain-Specific language to describe different types of elasticity strategies in a unified way. We define a formal model that captures a set of QoS metrics and defines elasticity operations. This model will also be used to define and verify elasticity strategies. We will also work on the alignment of Service Level Agreements with the elasticity strategies

Abstract:

Un système orienté-services est un système logiciel destiné à être re-conçu incrémentalement pour fournir à ses utilisateurs de nouvelles options. Ceci amène à modifier et / ou enrichir certains comportements du systèmes. La modification de tels comportements est appelée service. Les services sont conçus et intégrés indépendamment les uns des autres. Cette indépendance a pour effet d'induire des comportements du système non prévus. Ces derniers sont appelés : Interactions. Dans le cadre des méthodes formelles, il existe plusieurs caractérisations de la notion d'interaction, mais ces dernières dépendent de la logique sous-jacente. Dans cette thèse, nous proposons des définitions génériques des notions de services, systèmes orienté-services et interaction. Ces dernières sont caractérisées dans la théorie des institutions. A partir d'une institution quelconque, nous montrons comment définir une nouvelle institution dédiée à spécifier des services. Puis nous montrons comment composer ces services de façon à modéliser les systèmes de services et l'opération d'intégration de services. Les interactions sont alors mises en lumière par l'étude de deux types de propriétés : Les propriétés émergentes qui dénotent des comportements du système non prédits par la description du service et les propriétés de non-conformités qui dénotent des comportements promis par la description du services et qui ne sont pas des comportements du système. Dans la dernière partie de la thèse, nous montrons comment ces propriétés sont conservées au travers de primitives d'enrichissement et de raffinement. Dans les deux cas, (enrichissement et raffinement), nous montrons que les propriétés émergentes sont préservées (bien que de nouvelles puissent apparaître) alors que les propriétés de non conformité peuvent disparaître. Finallement, nous proposons d'imposer des conditions suffisantes pour obtenir une conservation complète des propriétés émergentes et de non-conformité
Feature-oriented systems are software systems which are incremently re-designed in order to provide new options to their users. This leads to modify and / or enrich some oldest systeme behaviors. The description of such a behavior modification is called a feature. Features are designed and integrated in an independant way. This independance leads to unpredicted behaviors which are called interactions. In the frame formal methods, there exists several characterisations of the notion of interaction, but all if them depends on the underlying logic of the formal methods of interest. In this thesis, we propose generic definitions of the notions of feature, feature-oriented systems and feature interactions. Those latest are grounded in the theory of institutions. From any arbitrary institution, we show how to define a new institution devoted to feature specifying. Then we show how to compose those features in order to model feature systems and feature integrations. Interactions are the enlighted by the study of two kind of properties : The emerging properties which denotes behaviors of the system unpredicted by the feature description, and non-conformance properties which denotes behaviors promissed by the feature description which are not behaviors of the system. In the last part of the thesis we show how those properties are preserved through enrichments and refinements. In the both case (enrichment and refinement) we show that emerging properties are preserved (enventhough some new ones may appear) While some non-conformance properties may disappear. Finally we propose to impose sufficient conditions in order to obtain complete preservation of emerging and non-conformance properties

Abstract:

L'Orienté Service (SOA) est un paradigme de conception qui facilite la construction d’applications extensibles et reconfigurables basées sur des artefacts réutilisables qui sont les services. Ceux-ci sont structurés via des interfaces bien définies et publiables et qui peuvent être dynamiquement découvertes.Beaucoup d’approches ont été proposées dans la littérature pour la réingénierie d’applications existantes développées dans des paradigmes pré-services, principalement l’orienté objet, vers SOA. L’objectif est de permettre de sauvegarder la valeur métier de ces d’applications tout en leur permettant de bénéficier des avantages de SOA. Le problème est que ces approches s'appuient sur des critères ad-hoc pour identifier correctement des services dans le code source des applications existantes.Par ailleurs, l'une des caractéristiques les plus distinctives d'une application orientée service est sa capacité de se reconfigurer dynamiquement et d'adapter son comportement en fonction de son contexte d'exécution. Cependant, dans les langages de description d'architecture (ADL) existants dont l’aspect de reconfiguration et pris en compte, les règles de reconfiguration sont représentées d'une manière ad-hoc; en général, elles ne sont pas modélisées d'une manière explicite mais enfouillées dans la description de l'architecture. D'une part, ceci engendre une difficulté de la gestion de la reconfiguration dynamique au niveau de l'architecture et d’autre part, la traçabilité de la description de la reconfiguration dynamique à travers les différents niveaux d'abstraction est difficile à représenter et à gérer.Afin de surmonter les problèmes précédents, nous proposons dans le cadre de cette thèse deux contributions. D'abord, nous proposons une approche d'identification de services basée sur un modèle de qualité où les caractéristiques des services sont étudiées, raffinées et réifiées en une fonction que nous utilisons pour mesurer la validité sémantique de ces services. La deuxième contribution consiste en une proposition d'un langage de description d'architecture orientée service (ADL) qui intègre la description de la variabilité architecturale. Dans cette ADL les services qui peuvent constituer l’architecture, les éléments de contexte dont les changements d’état sont à l’origine des changements architecturaux, les variantes des éléments architecturaux sélectionnées en fonction des états des éléments de contexte et le comportement architectural dynamique sont ainsi spécifiés de façon modulaire
Service Oriented Architecture (SOA) is an architectural design paradigm which facilitates building and composing flexible, extensible and reusable service-oriented assets. These latter are encapsulated behind well-defined and published interfaces that can be dynamically discovered by third-party services. Before the advent of SOA, several software systems were developed using older technologies. Many of these systems still afford a business value, however they suffer from evolution and maintenance problems. It is advantageous to modernize those software systems towards service-based ones. In this sense, several re-engineering techniques propose migrating object-oriented applications towards SOA. Nonetheless, these approaches rely on ad-hoc criteria to correctly identify services in object-oriented legacy source code.Besides, one of the most distinguishing features of a service-oriented application is the ability to dynamically reconfigure and adjust its behavior to cope with changing environment during execution. However, in existing architecture description languages handling this aspect, reconfiguration rules are represented in an ad-hoc manner; reconfiguration scenarios are often implicit. This fact hinders a full management of dynamic reconfiguration at architecture level. Moreover, it constitutes a challenge to trace dynamic reconfiguration description/management at different levels of abstraction.In order to overcome the aforementioned problems, our contributions are presented in two axes: First, in the context of migrating legacy software towards SOA, we propose a service identification approach based on a quality measurement model, where service characteristics are considered, refined to measurable metrics in order to measure the semantic correctness of identified services. The second axis is dedicated to an Architecture Description Language (ADL) proposition that describes a variant-rich service-based architecture. In this modular ADL, dynamic reconfigurations are specified at architecture level. Moreover, the description is enriched with context and variability information, in order to enable a variability-based self-reconfiguration of architecture in response to context changes at runtime

This article introduces a n-gram-based approach to automatic classification of Web services using a multilayer perceptron-type artificial neural network. Web services contain information that is useful for achieving a classification based on its functionality. The approach relies on word n-grams extracted from the web service description to determine its membership in a category. The experimentation carried out shows promising results, achieving a classification with a measure F=0.995 using unigrams (2-grams) of words (characteristics composed of a lexical unit) and a TF-IDF weight.

Abstract:

The purpose of this study is to examine how and in what contexts the Swedish social services are discussed online. To answer this purpose we have studied two Swedish Internet communities, and looked into what was written about social services during a year’s span. To get an overview of our results, we found thematic analysis useful to distinguish general themes. We found, inter alia, that the social services is most often mentioned in the contexts of factual questions or when trying to rally public opinion against the social services. We also found that it’s in the contexts of economy, children, and alcohol and drugs that social services are present in Internet communities. The examined online discourse on Swedish social services was mostly objective and factual, and free from value statements, though often negative. The negative descriptions of the social services often refer to the position of power that the social services possess. It is far less frequent for the social services be described in a positive light.
Syftet med detta examensarbete var att undersöka i vilka sammanhang socialtjänsten förekommer i svenska internetfora samt hur socialtjänsten där framställs. För att besvara syftet genomfördes en netnografisk forskning där vi observerade vad som skrivits om socialtjänsten i fora. Vi avgränsade oss till två olika internetfora och gjorde vidare avgränsningar till inlägg aktuella under ett år och som innehöll ordet socialtjänst. För att få en bra överblick över det insamlade materialet gjordes en tematisk analys som resulterade i att två övergripande teman återfanns. Dessa två sammanhang var för att antingen efterfråga kunskap eller att väcka opinion. Inom dessa teman återfanns ytterligare tre sammanhang där socialtjänsten förekommer, dessa var gällande: ekonomi, barn och alkohol och droger. Framställningen av socialtjänsten påvisades vara ambivalent. I många inlägg återges socialtjänsten sakligt men det förekommer även att socialtjänsten framställs på ett negativt sätt. De negativa framställningarna av socialtjänsten syftar oftast på socialtjänstens maktposition. Mindre vanligt, men ändock förekommande, är att socialtjänsten framställs på ett positivt sätt.

ENGLISH ABSTRACT: Rehabilitation services, mainly rendered by therapists employed by the Department of Health, forms a critical part of the Primary Health Care (PHC) package of care. Different policies, within the Department of Health (DOH), provide guidance on rehabilitation service delivery. However, implementation of these policies remains a challenge. The current study aimed to describe and analyse the organisational capacity of rehabilitation services at the study site and to assess how congruent the rehabilitation service at the study site was with existing rehabilitation policy. A descriptive methodology was applied making use of both quantitative and qualitative methods in analyzing the organisational capacity of this study site and the alignment of rehabilitation services offered, with the National Rehabilitation Policy (NRP). The study used the Kaplan framework, the objectives of the NRP and specific selected articles of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) to develop indicators to be used for the description and analysis of the organisational capacity of the rehabilitation services at TC Newman Community Day Centre. Questionnaires based on seven objectives from the NRP were developed to collect quantitative data from five service providers, the facility manager of TC Newman CDC and the managers of two Non- Governmental Organisations (NGO) working in the drainage site. Face to face, audio recorded, semi- structured interviews were used to collect qualitative data from the five service providers. A folder audit and document review was used to enhance quantitative findings. After analysis of the data, I still felt the need for additional information and thus developed an open ended questionnaire for participants to complete. Barriers (e.g. defaulting of clients, a lack of standard documentation, poor monitoring and evaluation) and facilitators (e.g. outreach and support, competent staff and multi-disciplinary team) were identified in implementing the NRP. Participants highlighted the importance of accessing rehabilitation services with a focus on the outreach to peripheral clinics and funded NGO’s. Intersectoral collaboration is evident, but mainly with funded NGO’s. A lack of standardised documentation, inadequate monitoring and evaluation systems and uniformed documentation were some of the challenges identified by participants. The absence of participation by persons with disabilities was noted by all participants. With reference to the organisational capacity, the participants had a good understanding of rehabilitation within the PHC context. Participants felt confident in delivering rehabilitation services and were able to identify shortcomings in service delivery. It is concluded that rehabilitation services are not delivered exactly in accordance with the objectives of the NRP. However the organisation demonstrated capacity to deliver rehabilitation services at PHC level, but there is still a need to enhance service delivery on community based level. The results of this study gave me as a manager and implementer of health policy in the District Health System the opportunity to gain deeper insight as to how rehabilitation services are currently rendered. Results from the study highlighted how coherent rehabilitation service delivery is with current policy in health and the capacity of the organisation to deliver rehabilitation services. This gave me the opportunity to adjust and review current rehabilitation service delivery and implement changes, as the study progressed.
AFRIKAANSE OPSOMMING: Rehabilitasie word hoofsaaklik deur terapeute in die departement van gesondheid gelewer binne fasiliteite en vorm ‘n belangrike deel van die Primêre Gesondheid Sorg dienste (PGS). Daar is verskillende beleid binne die Departement van Gesondheid beskikbaar, wat rehabilitasie definieer. Ten spyte van beleid, bly die implimentering van hierdie beleide ‘n uitdaging. Hierdie studie het ontstaan om the kapasiteit van die organisasie te beskryf, om rehabilitasie dienste te implimenteer en ook te bepaal hoe hierdie dienste ooreenstem met die Nasionale Rehabilitasie Beleid (NRB). ‘n Beskrywende metodologie was gebruik, wat uit ‘n kwantitatiewe en kwalitatiewe deel bestaan het. ‘n Vraelys is ontwikkel op grond van die 7 doelwitte beskryf binne die NRB. Dit is gebruik vir die versameling van kwantitatiewe data, by vyf diensversakffers, `n gesondheidsbestuurder en die bestuurders van twee nieregerings organisasies. Kwalitatiewe data is verkry deur onderhoude met die vyf diensverskaffers. ‘n Oudit van pasiënt lêers en die evaluering van dokumente het kwantitatiewe data versterk. Na die analisering van data en die behoefte vir addisionele inligting, is ‘n oop-end vraelys ontwikkel en versprei na deelnemers om te voltooi. Die studie het die organisatoriese kapasiteit van die organisasie ontleed deur gebruik te maak van Kaplan se raamwerk vir organisasie kapasiteit en die doelwitte van die NRB, asook sekere geselekteerde artikels uit die “United Nations Convention of the Rights of Persons with Disabilities” UNCRPD. Deelnemers het belangrikheid van toegang tot rehabilitasie dienste bevestig, met ‘n fokus op uitreik na perifêre klinieke in die sub distrik en befondse Nie-Regerings Organisasies (NRO). Intersektorale skakeling was beskryf, maar beperk tot befondse NRO’s. Verskillende uitdagings soos bv. gestandardiseerde dokumentasie, onvoldoende monitering en evalueringssisteme en die dokumentering van inligting was geïdentifiseer. Die afwesigheid van persone met gestremdhede en hulle deelname by terapie was genoem deur deelnemers. Verskillende uitdagings asook fasiliteerders was geïdentifiseer deur deelnemers t.o.v die implementering van bestaande beleid.

OBJECTIVES: The purpose of this study is to describe clinical pharmacist services in a nurse practitioner (NP) run clinic and how clinical pharmacists might influence prescribing. METHODS: The description of the clinical pharmacist services is based on a 12-week experience of a clinical pharmacist and senior student pharmacist working with the nurse practitioner and nurse practitioner students. A questionaire was developed and consisted of items relating to the nurse practitioners ability to identify possible interactions of OTC medications, herbals and prescription medications. In addition, the questionnare assessed the comfort level of NP’s taking a prescription medication history, checking a patient’s prescription formulary, and selecting appropriate medication therapies. The questionaire uses a retrospective pretest format and was tested as a method of collecting data on how a pharmacist influenced NP prescribing. The site selected for this study was the Arizona State University Center for Healthcare Innovation (ASU Center) located in the heart of Downtown Phoenix (3rd Ave and Van Buren). RESULTS: Only one nurse practitioner worked at the ASU Center. The facility is new to the neighborhood and does not see many patients. The nurse practitioner partner in this project responded that working with a clinical pharmacist on a regular basis, with more patients would definitely help her hone skills necessary to identify interactions and prescribe according to a patients formulary. CONCLUSIONS: Pharmacists provide value-added services in an ambulatory care clinic run by nurse practitioners and provide valuable education and consultation on drug interactions. Pharmacist influence can be measured successfully to using a questionnaire in a retrospective pretest-posttest study design.

Abstract:

Dengue fever (DF) and dengue hemorrhagic fever (DHF) are emerging infectious diseases which are endemic in many regions of the globe, many of which are resource-poor areas. DHF and DF impose a severe economic health burden in tropical and subtropical areas. Dengue virus causes an acute febrile illness that can be a self-limited febrile illness, as seen in most cases of DF, or a life-threatening illness with plasma leakage and shock, as seen in cases of DHF. A systematic review of the literature revealed gaps in the knowledge base of clinical laboratory findings of dengue illness with regards to longitudinal dynamics and classification and predictive modeling of disease severity. The objective of this thesis was to investigate the utility of clinical laboratory variables for classification and prediction of disease outcomes. The data used in this investigation was derived from a prospective study of Thai children presenting to either of two study hospitals within 72 hours of onset of an acute febrile illness. Systematic data collection, including clinical laboratory parameters, and routine clinical management continued each day until 24 hours after the fever had subsided. A final diagnosis of DHF, DF, or other febrile illness (OFI) was assigned by an expert physician after chart review. The first research objective of this study was to describe the temporal dynamics of clinical laboratory parameters among subjects with DHF, DF, or OFI. Data were analyzed using lowess curves and population-average models. Quadratic functions of clinical variables over time were established and demonstrated significantly divergent patterns between the various diagnostic groups. The second research objective was to establish and validate tools for classification of illness severity using easily obtained clinical laboratory measures. Bivariate logistic regression models were established using data from one hospital in an urban area of Thailand as a training data set and validated with a second data set from a hospital in a rural area of Thailand. The validated models maintained a high sensitivity and specificity in distinguishing severe dengue illnesses without using the hallmark indicators of plasma leakage. The third research objective used classification and regression tree (CART) analysis to established diagnostic decisions trees using data obtained on the day of study enrollment, within the first 3 days of acute illness. Decision trees with high sensitivity were established for severe dengue defined either as: 1) DHF with evidence of shock (dengue shock syndrome, DSS); or 2) DSS or dengue with significant pleural effusion. This study expands existing knowledge of the potential utility of clinical laboratory variables during different phases of dengue illness. The application of the results of these studies should lead to promising opportunities in the fields of epidemiological research and disease surveillance to reduce the health burden, and improve the clinical management, of dengue illness. Future directions involve application of these algorithms to different study populations and age groups. Additionally, other analytical techniques, such as those involving CART analysis, can be explored with these data.

Abstract:

Le Luxembourg est le 3ème exportateur mondial de services financiers. Il figure parmi les pays qui accueillent le plus d’investissements directs en provenance de l’étranger, ce qui indique l’intensité de ses liens avec l’économie mondiale. Le but de ce travail est d’analyser l’influence éventuelle d’une économie mondiale caractérisée par l’interdépendance des marchés réels et financiers sur l’économie Luxembourgeoise. Chapitre 1 présente une analyse des interactions de l’économie Luxembourgeoise avec le monde extérieur. Le chapitre suivant est consacré à la revue de la littérature portant sur la modélisation de l’intermédiation financière au niveau macroéconomique, couvrant plusieurs types d’approches de modélisations. Enfin, le troisième chapitre comporte un modèle macroéconométrique multi-pays construit et analysé afin de simuler les scénarios plausibles. Le modèle y est présenté avec ses fondements théoriques, les résultats des simulations et une comparaison avec d’autres modèles. La nouveauté du modèle réside dans sa prise en compte du commerce international désagrégé en services financiers et autres, et des investissements internationaux en portefeuille avec leurs flux de titres et de capitaux, ainsi que de leur impact sur la croissance économique. Les résultats des simulations montrent que ce cadre d’analyse donne parfois des résultats différents par rapport aux modèles standards. Nombre de scénarios qui ne peuvent être simulés par d’autres modèles, tels que la baisse des flux internationaux d’investissements de portefeuille, sont également analysés et confirment la forte vulnérabilité du Luxembourg aux chocs externes qui ont lieu sur les marchés financiers
Luxembourg is world’s third financial services exporter and one of world’s top recipients of foreign direct investment in value as well as per capita terms, which highlight its strong linkages with world economy. The objective of this dissertation is to analyze possible outcomes for the very small and very open economy of Luxembourg in a world environment, where real and financial markets affect each other. To better understand the characteristics of the economy and economic mechanisms behind them, a thorough analysis with emphasis put on the interactions with the outside world based on available data and relevant literature is presented (Chapter 1). Subsequently a survey of literature devoted to modeling financial intermediation at macroeconomic level across various types of modeling approaches is offered (Chapter 2). Finally, a multi-country macroeconometric model built to simulate possible scenarios is presented and analyzed (Chapter 3) with its theoretical background, simulations’ results and comparison with other models. The model is novel in that it accounts for international trade disaggregated into financial services and the rest, and international portfolio investment in securities and equity flows, that have a significant impact on the country’s economic growth. Simulations’ results show that such a framework generates sometimes markedly different results than more standard models. A number of scenarios which cannot be simulated in other models, such as American stock market fall or a decrease in international portfolio flows, are also analyzed and confirm the high vulnerability of Luxembourg economy to external shocks originating in financial markets

Abstract:

Résumé: Ce mémoire présente une étude qualitative réalisée auprès des cadres supérieurs et des professionnels des équipes de 1" ligne en santé mentale jeunesse dans les onze CSSS de la Montérégie. Ces équipes, oeuvrant au sein des services de 1" ligne, ont été mises en place en 2001 afin d'améliorer l'accès aux services pour les enfants présentant des troubles mentaux. Les objectifs poursuivis par cette étude sont les suivants : décrire les pratiques émergentes au sein de ces équipes selon leurs modes d'organisation; identifier les facteurs facilitants et contraignants dans leur fonctionnement actuel; explorer les conditions et les modes de collaboration entre les différents partenaires internes et externes et finalement dégager une taxonomie des modèles d'organisation de ces équipes. La population à l'étude comprend les onze équipes situées dans les CSSS de la région de la Montérégie. La collecte de données a été effectuée en 2010-2011. Les principaux résultats de l'étude montrent l'importance de la diversité des contextes dans la mise en place de telles équipes qui sont encore en mode implantation. Les facteurs facilitant le fonctionnement de ces équipes sont inhérents à l'organisation, aux partenaires et à l'équipe. Les facteurs contraignants identifiés sont liés à l'organisation, aux cibles ministérielles, aux partenaires, à la clientèle, à l'équipe et à l'environnement. Les principales composantes discriminantes qui émergent de la taxonomie reposent sur deux axes : la collaboration et les forces et limites opérationnelles. Selon ces axes quatre modes différents ont permis de classer les équipes et de dégager un portrait exhaustif des modes d'organisation et de fonctionnement des équipes. Bonifier les modes de collaboration avec les partenaires internes et externes est un des éléments incontournables et prioritaires pour les divers acteurs concernés par les jeunes souffrant de trouble de santé mentale.||Abstract: This dissertation presents a qualitative study carried out with senior managers and professionals on the youth mental health teams in the eleven health and social service centres (CSSSs) in Quebec's Montérégie region. Working in frontline services, these teams were formed in 2001 to improve service access for children presenting mental health problems. They were also developed from an integrated network perspective to foster collaboration among all the various youth mental health services. The study objectives were the following: to describe the practices emerging in these teams based on their mode of organization; to identify facilitating and limiting factors in their current way of functioning; to explore the conditions and modes of collaboration with the various internal and external partners; and finally, to develop a taxonomy of the teams' organizational models. Data were collected in 2010-2011. The main study results show the importance of context diversity in setting up such teams, still in the implementation phase. Factors facilitating the team performance are inherent to the organization, the partners, and the team. Limiting factors identified are linked to the organization, ministerial targets, partners, the clientele, the team, and the environment. The main discriminants that emerged from the taxonomy lie upon two axes: collaboration, and operational strengths and limits. Based on these axes, four different modes were used to classify the teams and to produce an exhaustive portrait of their modes of organization and functioning. The taxonomy indicated that several changes are both required and feasible to optimize team functioning. The mode of collaboration is a major issue for teams working in an integrated service system. Improving modes of collaboration with internal and external partners is essential and a priority for all players concerned by youth suffering from mental health problems.

Abstract:

La démocratisation de la technologie de l’information et des moyens de communication ouvre la voie aux entreprises pour réaliser, via la coopération, certaines tâches complexes qui n’étaient pas à leur portée, soit du fait de leur taille (il s’agit souvent des petites ou moyennes entreprises), soit du fait des compétences requises pour la réalisation des tâches en question. L’objectif de cette thèse est de proposer une approche sémantique pour la coopération des workflows. Cette approche doit supporter la description, l’abstraction et l’interconnexion de workflows. Pour ce faire, nous proposons premièrement de décrire les sémantiques métiers et comportementale des workflows. Une telle description permet le partage des données d’une part, et facilite l’interconnexion automatique d’autre part. Deuxièmement, les workflows sont publiés dans un annuaire commun. Nous proposons dans cette thèse des structures de donnés permettant de stocker efficacement les workflows dans l’annuaire. Troisièmement, afin de préserver le savoir faire des différents partenaires participant à une coopération, nous proposons deux méthodes formelles pour l’abstraction des workflows. La première méthode se base sur des règles de réduction structurelle tandis que la deuxième se base sur la réduction du graphe représentant le comportement. Enfin, après l’abstraction et la publication de workflows, nous procédons dans la dernière étape à leur interconnexion. Pour faciliter cette interconnexion nous proposons un service de courtage pour la découverte des workflows. Ce service prend en compte les sémantiques métier et comportemental des workflows. Nous avons validé les solutions proposées à l’aide d’un prototype permettant l’interconnexion dynamique des compositions de services Web BPEL
The democratization of information technology and the mean of communication opens theway for the companies to carry out, via the cooperation, certain complex tasks which were notwith their range, either because of their size (they are often small or medium-sized companies),or because of competences necessary for the realization of the tasks in question. The objective of this thesis is to propose a semantic approach for the workflows cooperation. This approach must support the description, the abstraction and the interconnection of workflows. To reach this end, we firstly propose to describe business and behavioural semantics of workflows. Such a description allows sharing data on the one hand, and facilitates the automatic interconnectionon the other hand. Secondly, the workflows are published in a common registry. We proposein this thesis structures of data allowing to effectively store the workflows in the directory. Thirdly, inorder to preserve the know-how of the different partners taking part in a cooperation, we proposetwo formal methods for the abstraction of the workflows. The first method is based on structuralreduction rules while the second is based on the reduction of the graph representing the behaviour. Lastly, after the abstraction and the publication of workflows, we proceed in the last step totheir interconnection. To facilitate this interconnection we propose a broker for the discovery of theworkflows. This broker takes into account business and behavioural semantics of the workflows. We validated the proposed solutions using a prototype allowing the dynamic interconnection ofthe compositions of Web services BPEL

Abstract:

The vision of the Semantic Web aims at enhancing today's Web in order to provide a more efficient and reliable environment for both providers and consumers of Web resources (i.e. information and services). To deploy the Semantic Web, various technologies have been developed, such as machine understandable description languages, language parsers, goal matchers, and resource composition algorithms. Since the Semantic Web is just emerging, each technology tends to make assumptions about different aspects of the Semantic Web's architecture and use, such as the kind of applications that will be deployed, the resource descriptions, the consumers' and providers' requirements, and the existence and capabilities of other technologies. In order to ensure the deployment of a robust and useful Semantic Web and the applications that will rely on it, several aspects of the technologies must be investigated, such as whether the assumptions made are reasonable, whether the existing technologies allow construction of a usable Semantic Web, and the systematic identification of which technology to use when designing new applications. In this thesis we provide a means of investigating these aspects for service discovery, which is a critical task in the context of the Semantic Web. We propose a simulation and evaluation platform for evaluating current and future Semantic Web technology with different resource sets and consumer and provider requirements. For this purpose we provide a model to represent the Semantic Web, a model of the evaluation platform, an implementation of the evaluation platform as a multi-agent system, and an illustrative use of the platform to evaluate some service discovery technology in a travel scenario. The implementation of the platform shows the feasibility of our evaluation approach. We show how the platform provides a controlled setting to support the systematic identification of bottlenecks and other challenges for new Semantic Web applications. Finally, the evaluation shows that the platform can be used to assess technology with respect to both hardware issues such as the kind and number of computers involved in a discovery scenario, and other issues such as the evaluation of the quality of the service discovery result.

Abstract:

Avec l’émergence du "Cloud-computing" et des applications mobiles, il est possible de trouver un service web répondant à presque tout besoin. De plus, les développeurs peuvent créer des applications complexes en combinant différents services indépendants, dont l’agencement et l’exécution peuvent être automatisés avec l’aide de langages d’orchestration. Cependant, la diversité des technologies et le manque de standardisation peuvent entraver la collaboration entre services. Un exemple de cette limitation est le cas de la gestion des photos avec des services tels que Flickr et Picasa, qui diffèrent non seulement sur la façon dont les photos sont organisées mais aussi sur les services qu’ils fournissent. L’hétérogénéité de ces deux services conduit à des problèmes d’interopérabilité, à savoir dans l’adaptation, l’intégration et la coordination. Nous proposons un framework pour aider à la résolution de ces problèmes, sous la forme d’une architecture qui intègre différents langages d’orchestration avec des fournisseurs de services hétérogènes autour d’un langage pivot. Comme langage pivot, nous proposons le langage d’orchestration Criojo qui implémente et étend le Heta-calcul, un calcul original associé à une machine chimique abstraite dédié à l’orchestration de services. En adoptant cette approche l’interopérabilité entre les services et les langages d’orchestration sera améliorée, facilitant ainsi le développement des services composites. Le haut niveau d’abstraction de Criojo pourrait permettre aux développeurs d’écrire des orchestrations très concises puisque les échanges de messages sont représentés d’une manière naturelle et intuitive
With the emergence of cloud computing and mobile applications, it is possible to find a web service for almost everything. Moreover, developers can create complex applications by combining several independent services, whose arrangement and execution can be automated with the aid of orchestration languages. Nevertheless, the diversity of technologies and the lack of standardization can hinder the collaboration between services. An example of this limitation is the case of photo management with services such as Flickr and Picasa,which not only differ on the way photos are organized, but also in the services they provide. The heterogeneity of the two services leads to interoperability problems, namely adaptation, integration and coordination problems. We propose a framework for helping at the resolution of these issues, in the form of an architecture that integrates different orchestration languages with heterogeneous service providers around a pivot language. As a pivot language we propose an orchestration language based on the chemical programming paradigm. Concretely, this dissertation presents the language Criojo that implements and extends the Heta-calculus, an original calculus associated to a chemical abstract machine dedicated to service-oriented computing. The consequence of adopting this approach would bean improvement in the interoperability of services and orchestration languages, thus easing the development of composite services. The high level of abstraction of Criojo could allow developers to write very concise orchestrations since message exchanges are represented in a natural and intuitive way

Most Fire and Rescue services and Medical Emergency services are organised along the lines of one of two schools originating in the United Kingdom and in Germany. In order to present these schools we first decided to analyse the history of the regulations they operate under, by writing them in the form of a generic equation: f(Risks, Operational Resources, Time to attend). Fundamental differences regarding officer status, allocation, operational resources quality and quantity, recording of planned vs. Actual performance indicators, etc. Became apparent. We then solved the proposed equation for Austria, Denmark, Sweden, Finland, Switzerland and France. Finally, we demonstrated the cost-efficiency of Fire and Rescue services and Medical Emergency services when considered in association with the economic structures they have to protect

Abstract:

Magister Public Health - MPH
The reproductive health of women is hugely dependent on the involvement of their male partners. Men also serve as gatekeepers to women’s access to reproductive health services. Male involvement is an important recommendation for the Prevention of Mother-to-Child Transmission of HIV (PMTCT) program as their participation in antenatal care and HIV testing has been found to decrease infant HIV infection and increase HIV free survival. Male involvement is not just about promoting men to accompany their partners to antenatal clinic, but for men to provide supportive roles in their families, and also to bring men into HIV preventive and care services. Male involvement in PMTCT is defined as the fathers’ active involvement in attending antenatal care services and HIV testing during the antenatal period as well as the couple’s acceptance of PMTCT if the mother is found to be HIV positive. Men are traditionally not directly involved in their partner’s health in many sub-Saharan countries, although they most often make decisions about use of services. They may provide financial support but attending health services with their partner is not seen as part of the male’s role. There are therefore huge challenges in efforts to get men involved in reproductive health services and there is a need to better understand how to promote male involvement in different settings. Male involvement in PMTCT was adopted by the Zambian Government in 1999 but not much is known on how best to initiate and develop male involvement in their partner’s health.

Abstract:

The primary intent of this study is to examine the effects of an outdated job description plan in the Division of Youth Services within the Department of Human Resources. Specifically, this study focuses on the Court Service Workers1 position. An attempt has been made to analyze the impact of an outdated job description plan on the validity of job information, career advancement and compensation of the Court Service Workers. Job descriptions are primary sources of information for all aspects of Human Resource Planning - creating job description is the first important step in translating the goals of the organization into employee work activities. Reliable manpower planning cannot occur without the information that the job descriptions provide - the who, what, when and how of manpower planning cannot be resolved without this information base, hence job description information has to be regularly updated and valididated. The major findings of this study are that the job description utilized for the position of Court Service Workers is outdated because it has not been revised since 1981. This situation has therefore resulted in inadequate compensation for the incumbents of the position. In addition, the position offers only limited career advancement to these workers. The sum total of these problems has resulted in low morale and dissatisfaction among the workers. The main sources of information for this study were obtained from interviews conducted with the Court Service Workers and the Director of Field Services as well as questionnaires sent to the Court Service Workers. Secondary data were obtained from books, documents, pamphlets, reports and journals.

Abstract:

Current technology for locating and validating composite services are not sufficient due to the following reasons. Current frameworks do not have the capacity to create complete service descriptions since they do not model all the functional aspects together (i.e. the purpose of a service, state transitions, data transformations). Those that deal with behavioural descriptions are unable to model the ordering constraints between concurrent interactions completely since they do not consider the time taken by interactions. Furthermore, there is no mechanism to assess the correctness of a functional description. Existing semantic-based matching techniques cannot locate services that conform to global constraints. Semantic-based techniques use ontological relationships to perform mappings between the terms in service descriptions and user requests. Therefore, unlike techniques that perform either direct string matching or schema matching, semantic-based approaches can match descriptions created with different terminologies and achieve a higher recall. Global constraints relate to restrictions on values of two or more attributes of multiple constituent services. Current techniques that generate and validate global communication models of composite services yield inaccurate results (i.e. detect phantom deadlocks or ignore actual deadlocks) since they either (i) do not support all types of interactions (i.e. only send and receive, not service and invoke) or (ii) do not consider the time taken by interactions. This thesis presents novel ideas to deal with the stated limitations. First, we propose two formalisms (WS-ALUE and WS-π-calculus) for creating functional and behavioural descriptions respectively. WS-ALUE extends the Description Logic language ALUE with some new predicates and models all the functional aspects together. WS-π-calculus extends π-calculus with Interval Time Logic (ITL) axioms. ITL axioms accurately model temporal relationships between concurrent interactions. A technique comparing a WS-π-calculus description of a service against its WS-ALUE description is introduced to detect any errors that are not equally reflected in both descriptions. We propose novel semantic-based matching techniques to locate composite services that conform to global constraints. These constraints are of two types: strictly dependent or independent. A constraint is of the former type if the values that should be assigned to all the remaining restricted attributes can be uniquely determined once a value is assigned to one. Any global constraint that is not strictly dependent is independent. A complete and correct technique that locates services that conform to strictly dependent constraints in polynomial time, is defined using a three-dimensional data cube. The proposed approach that deals with independent constraints is correct, but not complete, and is a heuristic approach. It incorporates user defined objective functions, greedy algorithms and domain rules to locate conforming services. We propose a new approach to generate global communication models (of composite services) that are free of deadlocks and synchronisation conflicts. This approach is an extension of a transitive temporal reasoning mechanism.

RDF has become a relevant data model for describing and modeling information on the Web but providing scalable solutions to store and retrieve RDF data in a responsive manner is still challenging. Within the context of this thesis we propose a middleware devoted to storing, retrieving synchronously but also disseminating selectively and asynchronously RDF data in a fully distributed environment. Its purposes is to allow to leverage historical information and filter data near real-time. To this aims we have built our system atop a slightly modified version of a 4-dimensional Content Addressable Network (CAN) overlay network reflecting the structure of an RDF tuple. Unlike many existing solutions we made the choice to avoid hashing for indexing data, thus allowing efficient range queries resolution. Near realtime filtering is enabled by expressing information preferences in advance through content-based subscriptions handled by a publish/subscribe layer designed atop the CAN architecture. We have proposed two algorithms to check RDF data or events satisfaction with subscriptions but also to forward solutions to interested parties. Both algorithms have been experimentally tested for throughput and scalability. Although one performs better than the other, they remain complementary to ensure correctness. Along with information retrieval and dissemination, we have proposed a solution to enhance RDF data distribution on our revised CAN network since RDF information suffers from skewness. Finally, to improve maintainability and reusability some efforts were also dedicated to provide a modular middleware reducing the coupling between its underlying software artifacts

Abstract:

On the 26th of May 2021 the new regulation for medical devices, MDR 2017/745, will come into force. The underlying incentives to go from the medical device directive (MDD 93/42/EEC) to MDR are a series of adverse events involving medical devices. The main goal of MDR is to strengthen and improve the already existing legislation and thus will entail large changes for manufactures, one of them being manufacturers of Electronic Health Record (EHR) systems. For medical software, such as EHR systems, the new regulation will imply an upgrade in risk classification. This upgrade will bring additional requirements for EHR manufacturers. Furthermore, the released guidelines have been insufficient regarding the specific requirements for medical device software and thus EHR manufacturers are in need of tools and guidance to fulfill MDR. This thesis examines the new regulation for medical devices and thus identifies main requirements for EHR manufacturers. A qualitative approach was conducted comprising a literature study as well as a document study of the medical device regulation along with interviews with experts within the field of medtech regulatory affairs and quality assurance. The information gathered was analyzed to create a process description on how EHR manufacturers are to fulfill MDR. The process description is a general outline and presents the main steps on the route to be compliant with MDR in a recommended order of execution. The main steps are: divide the system into modules, qualify the modules, classify the modules, implement a quality management system, compile a technical documentation, compile the declaration of conformity, undergo a conformity assessment and finally, obtain the CE-mark. To each of the main steps additional documentation provides further information and clarification. The process description functions as a useful tool for EHR manufacturers towards regulatory fulfillment. Even though the process description is created for EHR manufacturers, it can be useful for other medical device software manufacturers. The process description provides an overview of the path to a CE mark and functions as a guidance. It can be used in educational purposes as well as to serve as a checklist for the experienced manufacturer to make sure everything is covered. However, it is not sufficient to rely solely on the process description in order to be in full compliance with MDR. Moreover, there is still a need for further clarifications from the European Commission regarding specific requirements on medical device software.
