Повний текст джерелаThe increasing usage of information technology in military affairs raises the need for robust high capacity radio networks. The network will be used to provide several different types of services, for example group calls and situation awareness services. All services have specific demands on packet delays and packet losses in order to be fully functional, and therefore there is a need for a Quality of Service (QoS) mechanism in the network.
In this master thesis we examine the possibility to provide a QoS mechanism in Ad Hoc networks by using priority queues. The study includes two different queuing schemes, namely fixed priority queuing and weighted fair queuing. The performance of the two queuing schemes are evaluated and compared with respect to the ability to provide differentiation in network delay, i.e., provide high priority traffic with lower delays than low priority traffic. The study is mainly done by simulations, but for fixed priority queuing we also derive a analytical approximation of the network delay.
Our simulations show that fixed priority queuing provides a sharp delay differentiation between service classes, while weighted fair queuing gives the ability to control the delay differentiation. One of those queuing schemes alone might not be the best solution for providing QoS, instead we suggest that a combination of them is used.

Повний текст джерелаNowadays a lot of systems are residing in distributed environments. These systems are composed of the client side software and server side software. That is called distributed systems architecture. Those types of systems can contain many services and many clients and may be substituted of many databases and many services. Distributed software components do not always run at the same time, networks, especially wide-area networks, are not always available and reliable. These parts communicate using remote procedure calls, or request/response messages and message queues. In this work we research third party components which are used to communicate between parts of distributed systems using messages and Microsoft message queues. The research is performed on two chosen components, which best fits in the developed system’s context. The choice of components and research based on usability problems using developed system called Business layer framework. The obtained results evaluated using user recommendation form.

Повний текст джерелаThis paper discusses the application of discrete simulation for the management of queues in the service sector. Some service providers do not correctly dimensioning its service capacity generating queues. The efficient management of queues assists managers in making decisions. The characteristics of services and their important activities are addressed, aiming to demonstrate the Computational Simulation utility to find a balance that satisfies the customer and is economically viable for the service manager. The study object is a self-service restaurant. Through the Software ARENA was developed a model of discrete type and stochastic to play everyday restaurant setting. It concludes that the discrete simulation software has modeling elements that meets the application requirements. The studied restaurant has different characteristics from traditional self-service with layout in series, and it was necessary to provide the model a route for the flow of customers. The study concluded that the queues occur in the mass preparation process, special meat preparation and boxes, with average waiting times of up to 5 minutes. In the other processes, which are trim service, salad - dessert, scale and location of a table - chair is available, the queues have a very agile flow. The operating model obtained allowed the evaluation of some scenarios aiming to reduce the queue time.
Este trabalho discute a aplicação da simulação discreta para a gestão de filas no setor de serviços. Alguns prestadores de serviços não dimensionam corretamente sua capacidade de atendimento gerando assim as filas. A gestão eficiente das filas auxilia os gestores na tomada de decisões. São abordadas as características das atividades de serviços e sua importância, tendo como objetivo demonstrar a utilidade da Simulação Computacional para se encontrar um ponto de equilíbrio que satisfaça o cliente e seja viável economicamente para o gestor do serviço. O objeto de estudo é um restaurante selfservice. Através do Software ARENA foi desenvolvido um modelo do tipo discreto e estocástico para reproduzir o ambiente diário do Restaurante. Conclui-se que o software de simulação discreta possui elementos de modelagem que atende as necessidades da aplicação. O restaurante estudado possui características diferentes do tradicional selfservice com layout em série, e foi necessário prever no modelo um roteamento para o fluxo de clientes. O estudo concluiu que as filas ocorrem nos processos de preparo de massas, preparo de carnes especiais e caixas, com tempos médios de espera de até 5min. Nos demais processos, que são serviço de guarnição, salada-sobremesa, balança e localização de uma mesa-com cadeira disponível, as filas possuem um fluxo bem ágil. O modelo operacional obtido permitiu a avaliação de alguns cenários visando diminuição do tempo de fila.

Tree networks of single server, deterministic service time queues are often used as models for packet flow in systems with ATM traffic. In this thesis, we present methods of analyzing packet occupancy in these systems. We develop general theorems which enable the analysis of individual nodes within a multi-stage system to be reduced to the analysis of a simpler single-stage or 2- stage equivalent model. In these theorems, we make very few assumptions about the nature of the exogenous input processes themselves, and hence our results apply to a variety of input sources. In particular, we treat three input source cases: bursty on/off inputs, periodic continuous bit rate (CBR) inputs, and discrete time Generalized Independent (GI) inputs. For each of these input sources, we derive mean queue lengths for individual nodes and aggregate occupancy distribution functions for multi-stage systems. For GI-type inputs (which includes memoryless inputs), we derive explicit expressions for the means and variances of packet occupancy in any node of a multi-stage, deterministic service time tree network. We also create a general definition of a "distributable input," which includes any collection of M sources which run independently and are identically distributed (iid) according to some arbitrary type of arrival process (in particular, this includes periodic CBR sources). We demonstrate that the expected occupancy of a single-stage system is a convex, monotonic function of the distributable input loading. Furthermore, the expected occupancy of any node within a multi-stage tree network is a concave function of the multiple exogenous input loadings at the upstream nodes.

Повний текст джерелаDetta projekt behandlar modellering och optimering av ett kösystem samt personalvård på organisationer och är utformad som en fallstudie av en telefonkundtjänst. Kundtjänstsystem har blivit en viktig del av de flesta, om inte alla, moderna affärssystem tack vare dess roll som ett primärt kommunikationsinstrument för företag och kunder. Härav följer stort akademiskt och praktiskt intresse för välfungerande kundtjänstsystem och inte minst för personalvården. Det sistnämnda är en viktig faktor som påverkar en rad aspekter såsom kundtjänstsystemets effektivitet, servicekvalitet och personalomsättning. Teorin bakom kömodellering och simulering hittas i kapitel 2, som följs av dataöverblick i nästa kapitel. Tillvägagångssättet vid kömodelleringen beskrivs i kapitel 4 och inkluderar databearbetning, estimering av intensiteter samt simulering av liknande datamängder med de framtagna intensiteterna som utgångspunkter. Simuleringar används dessutom för att ta fram scheman, visa beroendet mellan variabler måluppfyllnad och budget och kontrollera modellens träffsäkerhet. Optimalt arbetsschema för olika budgetmålsättningar ställs upp och presenteras i slutet på kapitel 5. Modellens träffsäkerhet och implikationer av studiens resultat diskuteras i kapitel 6. Kapitel 7 är dedikerad till personalvård. Först vänder vi oss till teoretiska grunder av organisationsteori och dess HR-perspektiv. Översikt på hur personalvård ser ut på en kundtjänstavdelning vars kösystem har modellerats ges i 7.3.1. Den delen följs av fallstudien av ett bolag T-Mobile. Sedan markeras olika moment av personalvård i diskussionsdelen. Slutsatser sammanfattas i kapitel 8.

Повний текст джерелаO objetivo deste trabalho final de mestrado (TFM) é o estudo de modelos de Investigação Operacional, para resolver um problema sentido nos serviços de receção de utentes do Instituto Português de Reumatologia (IPR). Durante o estágio nesta instituição foi identificada a dificuldade em dar resposta, de forma rápida, ao elevado número de utentes que se concentram na sala de espera em certos períodos de tempo, provocando desequilíbrios na agenda dos médicos e tensão nas salas de espera. Estes utentes têm de aguardar pelo serviço de receção por diferentes razões: dar entrada para consultas, marcar novas consultas ou exames, efetuar pagamentos de exames, receber informações sobre o funcionamento do instituto e ainda concluir processos de internamento. Com o objetivo de obter possíveis soluções para este problema, a metodologia proposta neste relatório foi a construção de dois modelos matemáticos: modelo de programação linear inteira e modelo de simulação. Foram estudadas diversas propostas de reorganização do serviço de receção do instituto, utilizando o modelo de simulação. O modelo de programação linear inteira foi utilizado para resolver instâncias do problema com o objetivo de determinar o número mínimo de balcões necessários para o fluxo esperado de utentes, usando dados recolhidos no IPR e dados da simulação. Com base na análise dos indicadores dos modelos de simulação concluiu-se que a melhor proposta seria a da marcação da próxima consulta pelos médicos. De acordo com as soluções obtidas pelas diversas instâncias do modelo de programação linear inteira, concluiu-se que um dos balcões não está em funcionamento na maioria dos turnos. Foi ainda construído um modelo em Excel que permite aos funcionários decidir, em tempo real, o número de balcões que deverão abrir em cada turno, conhecendo o número e tipo de utentes que estão em fila de espera.
The purpose of this internship report is to study some models of Operational Research, so that the problem that is felt by the users at the reception desk of the Portuguese Institute of Rheumatology (IPR) can be solved. During the internship at this institution the problem that was identified was the difficulty of the reception desk in giving a quick answer to the numerous users that are in the waiting room at certain hours. This causes a certain imbalance in the doctors’ schedules and also some tension in the waiting room. The reasons why the users have to wait at the reception desk are the following: admission to appointments, schedule of new appointments or medical exams, paying for the provided services, getting information about the functioning of the institute and also concluding the hospitalization process. In order to obtain possible solutions to this problem, the proposed methodology for this report was to build two mathematical models: linear integer programming model and simulation model. Several proposals for reorganizing the reception desk service were carried out by using the simulation model. Based on the data gathered from the IPR and from the simulation model, the integer linear programming model was used to solve the problem instances, in order to determine the minimum number of service counters that is necessary to handle the users expected flow. By analyzing the simulation model indicators we came to the conclusion that the best proposal would be the scheduling of the new appointments by the doctors. According to solutions provided by the several instances of the integer linear programming model, we can conclude that one of the service counters of the reception desk doesn’t function in most shifts. Guided by the number and type of users that are queuing, an Excel model was constructed. It allows the employees to decide, in real time, the number of service counters that should be open each shift.

Повний текст джерелаWith regard to a comtemporaneous person represented in a society caracterized by individualism two concepts get a meaning together: collective identities and social exclusions. This study takes place within a few institutions specialized in social work, during a sociologist's professional experiences (asylum, social home for adults, social worker training school). The sociologist's involvement with an institutional action, led her to present some of her social functions while being in a situation of intervention. Part 1 is a presentation of theories, and both analysis and action patterns which orientate the sociologist's research and act. Based on a biographical approach, a discussion on theories, social life stories and social protagonists follows in part 2. Grisis, violence, repetition and changes punctuate the day to day life in the surveyed institutions. Observed social logics variously enlighten the project for communication and insertion. This project is the basis for social exclusion today. The training of collective identities question the will that the other person be recognized with all his differences

Повний текст джерелаEnterprises typically have their data spread over many software systems, such as custom made applications, CRM systems like SalesForce, CMS systems, or ERP systems like SAP. In these setting, it is often desired to integrate information from many data sources to accomplish some business goal in an application. Data may be stored locally or in the cloud in a wide variety of ways, demanding for explicit transformation processes to be defined, reason why it is hard for developers to integrate it. Moreover, the amount of external data can be large and the difference of efficiency between a smart and a naive way of retrieving and filtering data from different locations can be great. Hence, it is clear that developers would benefit greatly from language abstractions to help them build queries over heterogeneous data sources and from an optimization process that avoids large and unnecessary data transfers during the execution of queries. This project was developed at OutSystems and aims at extending a real product, which makes it even more challenging. We followed a generic approach that can be implemented in any framework, not only focused on the product of OutSystems.

Повний текст джерелаLa mortalité maternelle reste encore élevée dans les pays en développement notamment en Afrique où une femme parmi 16 en âge de reproduction sera touchée par cette mortalité contre 1 femme parmi 2400 dans les pays développés. Au Burkina Faso, ce risque de mortalité est de 1 parmi 12 pour une femme en âge de reproduction.
La littérature internationale montre qu’un meilleur accès aux soins qualifiés à l’accouchement et aux soins obstétricaux d’urgence est la solution majeure pour sauver la vie d’une femme au cours de la grossesse, de l’accouchement et dans le post partum. Elle montre que cet accès est limité en milieu rural par l’existence de barrières liées aux services de santé, de barrières économiques et sociales. Au milieu des années 1990, il a été montré qu’il serait possible d’améliorer l’accès des femmes aux soins qualifiés et aux soins d’urgence par des interventions locales visant à réduire ces barrières. Ces résultats ont entraîné la mise en place de plusieurs interventions en milieu rural burkinabè. L’objectif de cette thèse est d’examiner les activités mises en place au niveau du système de santé dans les districts ruraux de Houndé et d’Orodara au Burkina Faso afin de mieux comprendre ce qui a été à la base de l’évolution des indicateurs de santé maternelle.
Méthodologie
Le travail a combiné des méthodes quantitatives et qualitatives. Des études de cas, plusieurs sources d’informations (revue des documents, interview des populations, prise de notes, observation participante) ont été utilisées pour identifier au niveau du système de santé des districts les activités pouvant influencer l’utilisation des soins obstétricaux d’urgence et analyser la dynamique et la qualité de leur mise en œuvre. Des approches quantitatives (étude écologique, analyse transversale, étude avant et après) ont permis d’étudier l’évolution des indicateurs et de mettre celles-ci en parallèle avec la réalisation de certaines activités. Enfin, les résultats dans les deux districts ont été comparés avec ceux d’autres districts ayant aussi bénéficié d’une intervention en santé maternelle.
Résultats
L’analyse du système de santé a identifié l’existence d’activités d’éducation et de mobilisation des populations, d’amélioration de l’environnement de la prise en charge de la femme enceinte et de renforcement de compétence des agents de santé et des accoucheuses villageoises dans les deux districts. Dans le district de Houndé une intervention bien structurée (le projet SAREDO) avec analyse des besoins a été à la base d’une grande partie des activités de 2000 à 2003. Mais l’analyse de la mise en oeuvre des activités de ce projet a montré des écarts par rapport à ce qui avait été planifié, des retards et un manque de suivi des activités. Ces faiblesses du projet étaient liées à l’approche participative de mise en œuvre, à des faiblesses organisationnelles et à l’arrêt avant terme du financement. Dans le district d’Orodara, la mise en place des activités a démarré avec l’arrivée en 2001 d’un médecin chef en provenance du district de Houndé. Aucune intervention planifiée n’a existé. Les activités ont été mises en place à partir de décisions empiriques s’inspirant de l’expérience du projet SAREDO à Houndé. Dans les deux districts, la collaboration avec des intervenants dans et hors du district, le leadership de l’équipe de district et l’utilisation rationnelle des ressources ont été déterminants dans la mise en œuvre des activités.
L’évolution des indicateurs de soins maternels a montré une amélioration de l’utilisation des soins maternels en général de 1999 à 2006 dans les deux districts. En 2004, si l’utilisation des services de consultation prénatale et de maternité pour l’accouchement était meilleure à Houndé qu’à Orodara, il n’existait aucune différence pour ce qui était du taux des accouchements par césarienne. Pour ce dernier indicateur, on notait une croissance linéaire dans le district de Houndé, tandis qu’à Orodara, le taux était resté stable de 1999 à 2002 et à partir de 2003 on assistait à une amélioration avec un taux atteignant celui de Houndé en 2005. La mise en parallèle de l’évolution du taux d’accouchements par césarienne et du calendrier des activités dans les deux districts montre une amélioration après la mise en place du renforcement de la qualité des soins (formation des agents et équipement) et de la réduction du coût des soins d’urgence surtout dans le district d’Orodara. Ces observations suggèrent l’existence d’une relation entre l’évolution du taux des accouchements par césarienne et, d’une part, le renforcement de la qualité des soins et d’autre part, la mise en place de la réduction du coût des soins d’urgence.
Une évaluation a relevé dans le district de Houndé que l’offre de soins était meilleure après la formation des agents de santé et l’équipement des services. Elle a aussi montré une meilleure utilisation des services de base (consultation prénatale et accouchements institutionnels) et un taux plus élevé d’évacuations obstétricales dans le groupe des centres de santé avec un responsable de la maternité ayant bénéficié de la formation que dans le groupe des centres de santé avec un agent non formé responsable de la maternité. Les proportions d’accouchements par césarienne et d’interventions obstétricales majeures réalisées pour sauver la vie de la mère étaient plus élevées dans le groupe des centres de santé avec un agent formé responsable de la maternité mais les différences n’étaient pas statistiquement significatives. Les résultats de cette évaluation montrent qu’au niveau des centres de santé de base, former les agents et équiper les services permettent d’améliorer la qualité et l’utilisation des services de base mais ne suffisent pas pour améliorer l’utilisation des soins obstétricaux d’urgence.
Au niveau de l’hôpital du district d’Orodara, après la mise en place des kits opératoires, les proportions des évacuations obstétricales à l’admission, des évacuations obstétricales prises en charge et des accouchements par césarienne à l’hôpital du district se sont améliorés significativement tandis que les proportions des complications infectieuses post césarienne et des évacuations obstétricales à l’hôpital de référence, et le coût des soins d’urgence ont été réduits. Ceci montre qu’en réduisant le coût des soins via les kits opératoires et en plus d’une formation des agents de santé, on a pu améliorer l’accès et la qualité des soins obstétricaux d’urgence dans cet hôpital.

Повний текст джерелаThis work presents a set of proposals in different domains, with the finality to create an organization model for SM (Mobility services) than can ensure them perennity, in order to prevent their dependance from public intervention. These proposals are a result of the in depth analysis and evaluation of a diversity of study cases in Europe, Japan, and United-States. Among these case studies fourteenth have been studied with special attention. They represent success, failure or mixed result cases. We have also analyzed the evolution of Public Transports, sustainable modes and SM in the last four decades, so as the conditions that allowed the development of SM in Europe. Finally, and in parallel to the proposals to construct an organization model for SM, we also propose some criteria to follow-up and evaluate SM. We used the diverse proposals in order to built an organization model for SM in the Ile-de-France region, as well as a sustainable financing plan for SM in this region

Toumi, Iqbal. "Les services publics au Maroc : quelles perspectives de développement et de financement ?" Perpignan, 2006. http://www.theses.fr/2006PERP0733.
Повний текст джерелаIn Morocco, the public service as a concept and public services as organisations and structures are being questioned, not only at the level of doctrine, conception and production and financing methods, but also at the level of economy and society in general; it is obvious that they are going through a crisis in terms of functioning and development and financing perspectives. In view of economic data and the results of highly detailed sectoral diagnostics carried out, and bearing in mind that the reality is contingent and relative, we can adopt a pragmatic approach of the public service which will answer the present and future financial needs of Morocco and at the same time reform the legitimacy of public service economic activities whilst combining them with the rules and principles of a participative democracy. Therefore, beyond dogmatic and doctrinarian choices and approaches, we put forward the idea, whilst at the same time asserting that tools and techniques taken from other environments should not be transposed before being given due consideration, that the partnership between the public and private sectors is the cornerstone upon which we can erect a global, economic and institutional instrument to boost the idea of public services and methods of production and alternative financing for Morocco. A successful implementation of a public/private partnership mechanism can only come about if accompanied by necessary measures in terms of : an institutional and legal framework on a national scale ; institutional structures guaranteeing economic regulation ; and an institutionalised user representation system

A growing trend in hiring maintenance services has been observed in companies in general in order to enhance competition and reduce costs. This practice becomes even more evident in the context of health institutions, as they strongly employ technology-intensive equipment that must follow tight quality standards that intend to ensure the continuity of the service and the safety of patients. These characteristics contribute in allowing the maintenance to be executed by the Original Equipment Manufacturer (OEM), since several pre-established procedures must be attended during maintenance. Thus, it becomes relevant to analyze the interaction among customers (hospitals) and the equipment manufacturer in this particular maintenance services market. In the developed model the customers are divided into 2 classes, great size hospitals belong to class 1 and small hospitals belong to class 2 and class 1 customers have priority over class 2 customers. Class 1 customers have the option of hiring an Extended Warranty (EW) with priority or of paying for each maintenance intervention on demand, while class 2 customers have the option of hiring an standard EW (with no priority) or of paying for each maintenance intervention on demand. To model such dynamics a 2-class priority queuing system is implemented. The customers select the option that maximize their expected utilities, as they are risk averse, while the manufacturer needs to set the EW and maintenance intervention prices and select the optimal number of customers of each class to service in order to maximize their expected profit. A Stackelberg Game is used to model the interaction among players, in which the OEM is the leader and the customer is the follower. In the numerical example it has been found that the customers of class 1 decide to hire EW with priority, while class 2 customers decide to pay for maintenance services on demand. Also the OEM decides to service 3 customers of class 1 and 100 customers of class 2, which yields an expected profit of $ 3,204,450. A sensitivity analysis is also performed to analyze how the optimal solution changes due to parameters variations.
Uma tendência crescente para a contratação de serviços de manutenção tem sido observada em empresas em geral com o objetivo de aumentar sua competitividade e reduzir custos. Tal prática se torna ainda mais evidente no contexto de instituições de saúde, já que elas utilizam diversos equipamentos intensivos em tecnologia que precisam se adequar a rígidos padrões de qualidade de forma a garantir a continuidade do serviço e a segurança dos pacientes. Essas características contribuem para que os serviços de manutenção sejam executados pelo fabricante do equipamento, já que diversos procedimentos específicos precisam ser seguidos durante a manutenção. Assim, torna-se relevante analisar a interação entre clientes (hospitais) e o fabricante do equipamento neste mercado particular. No modelo desenvolvido, os clientes foram divididos em 2 classes, hospitais de grande porte pertencem à classe 1 e hospitais pequenos pertencem à classe 2 e os clientes da classe 1 têm prioridade em relação aos clientes da classe 2. Os clientes da classe 1 têm a opção de contratar uma garantia estendida com prioridade ou de pagar por cada intervenção de manutenção sob demanda, já os clientes da classe 2 têm a opção de contratar uma garantia estendida padrão (sem prioridade) ou de pagar por cada intervenção de manutenção sob demanda. Para modelar esta dinâmica um sistema de filas com 2 classes de prioridade foi implementado. Os clientes escolhem a opção que maximiza suas utilidades esperadas, já que são avessos ao risco, enquanto o fabricante deve determinar os preços das garantias estendidas e das intervenções avulsas além do número ótimo de clientes que ele deve atender de forma a maximizar o seu lucro esperado. Para modelar a interação entre os jogadores foi utilizado um Jogo de Stackelberg em que o fabricante é o líder e o cliente, o seguidor. O exemplo numérico apresentado mostra que a decisão ótima para os clientes da classe 1 é adquirir a garantia estendida com prioridade, enquanto para os clientes da classe 2 a decisão-ótima é pagar pelos serviços de manutenção sob demanda. O fabricante decide atender 3 clientes da classe 1 e 100 clientes da classe 2, o que lhe gera um lucro de $ 3,204,450. Uma análise de sensibilidade é apresentada em seguida para investigar como a solução ótima muda em decorrência de variações nos parâmetros.

Повний текст джерелаA questionnaire designed for this study was administered to 199 males and females, aged 55 years and older, recruited from the only Anglophone Seniors' Centre in East-End Montreal. It was found that elderly people with limited French proficiency were more likely to travel out of their area for healthcare services, resulting in significantly longer average travel and waiting times. Of those who would have liked an interpreter, very few were actually able to get one. The most frequently expressed need was for more English or bilingual workers and services.
To improve access and enhance elderly people's quality of life, training and intervention programs need to be developed in collaboration with the government.

Повний текст джерелаThe mobile data landscape is changing rapidly and mobile operators are today facing the daunting challenge of providing cheap and valuable services to ever more demanding customers. As a consequence, cost reduction is actively sought by operators as well as Quality of Service (QoS) preservation. Current 3GPP standards for LTE/EPC networks offer a fine tuning QoS (per-flow level), which inherits many characteristics of legacy telco networks. In spite of its good performance, such a QoS model reveals costly and cumbersome and finally, it remains very rarely deployed, thereby giving way to basic best-effort hegemony. This thesis aims at improving QoS in mobile networks through cost-effective solutions; To this end, after an evaluation of the impact and cost of signaling associated with the standard QoS model, alternative schemes are proposed, such as the IP-centric QoS model (per aggregate) inspired from the DiffServ approach widely used in fixed IP networks. This model provides a simple, efficient and cost-effective IP level QoS management with a performance level similar to standardized solutions. However, as it requires enhancements in the eNB, this scheme cannot be expected in mobile networks before a rather long time.Thus, we introduce Slo-Mo, which is a lightweight implicit mechanism for managing QoS from a distant point when the congestion point (e.g. eNB) is not able to do it. Slo-Mo creates a self-adaptive bottleneck which adjusts dynamically to the available resources taking advantage of TCP native flow control. Straightforward QoS management at IP level is then performed in the Slo-Mo node, leading to enhanced customer experience at a marginal cost and short term

Повний текст джерелаLa réforme des soins de santé de première ligne occupe une place prioritaire parmi les réformes de santé, notamment avec une grande importance accordée à des équipes interdisciplinaires de professionnels de santé. Le modèle choisi par Québec, les groupes de médecine de famille (GMFs), a été mis en place à la fin de 2002. Ce modèle met l'emphase sur des équipes interprofessionnelles et vise à augmenter le nombre de Québécois avec un médecin de famille, ainsi qu'à offrir une plus grande accessibilité des services de la première ligne, notamment hors les heures normales de travail. Une décennie après leur implantation, j'ai étudié l'impact des GMFs sur diverses mesures d'accès aux soins de santé de première ligne. Je mets l'emphase sur l'accès potentiel – c'est-à-dire les mesures permettant de déterminer si un individu a la possibilité d'accéder aux soins de santé nécessaires, y compris d'avoir un médecin régulier.J'ai utilisé des données de sept cycles de l'Étude sur la santé dans les collectivités canadiennes pour capturer l'accès déclaré aux soins de première ligne et obstacles à cet accès. Il existe une variation régionale dans l'implantation des GMFs à travers les différentes régions sociosanitaires du Québec, ce qui me permet de construire une mesure de participation aux GMFs constituée de la proportion des médecins de première ligne pratiquant en GMF par région sociosanitaire et par année. J'ai employé une analyse qui consiste de modèles de différence-dans-les-différences modifiées qui utilise une analyse de régression multivariée pour contrôler les tendances temporelles, les différences constantes entre les régions, et les covariables au niveau individuel, le but étant d'estimer l'effet causal de la mise en œuvre des GMFs sur l'accès aux soins de santé de première ligne.J'ai vérifié que les différences de caractéristiques populationnelles et socio-économiques dans la période pré-politique entre les régions ayant un taux élevé par rapport à celles ayant un faible taux de participation aux GMFs sont raisonnables et fixes au cours des années de mon étude, rendant ainsi toute comparaison de ces régions appropriées. Les résultats suggèrent que les taux d'accès déclarés ont augmenté au fil du temps dans la plupart des régions sociosanitaires du Québec. Toutefois, ces mesures d'accès varient selon les régions et certains signalent toujours des taux inférieurs d'accès. Contrôlant pour les tendances temporelles, les différences fixes entre les régions, et les caractéristiques individuelles, l'accès déclaré ne change pas de manière significative avec l'augmentation de la participation aux GMFs.Un meilleur accès aux soins de santé de première ligne constituait l'un des principaux objectifs explicites de la réforme des soins de santé de première ligne de 2002. Mes résultats suggèrent que l'augmentation de la participation aux GMFs n'a pas amélioré plusieurs mesures importantes d'accès. En conséquence, des politiques supplémentaires pourraient être nécessaires pour accroître l'accès potentiel aux soins de santé de première ligne.

Повний текст джерелаTransgender people are in society at large and in many different ways more disadvantaged than other groups in society. Simultaneously as the Swedish social services by law are obliged to promote equality in people's living conditions transgender people have a low trust and confidence in the social services. This is due to experiences of being poorly treated by professionals. This study focuses on social service workers in the Swedish social services and has the purpose to examine and illuminate social service worker´s approach to and way of working with clients who are transgender. The data in this study have been collected through ten semi-structured interviews with social service workers in a region in southern Sweden. The data have been analysed by the use of thematic analysis in order to bring forth patterns in the social service worker´s statements. By coding and thematization the thematic analysis generated three themes that this study labels as with the human as the outset, humancompetence in focus and as guideline and the human behind the role as a social service worker. The result of this study was analysed with the help of parts of Butler's queer theory as well as previous research on the field of concern. The common way of entering a meeting with a client is according to the social service worker's themselves to treat all clients in the same way and to attempt to see the human behind the client. In the specific meeting with a client who have a transgender identity it therefore comes down to meeting a human, not a transgender person.

Повний текст джерелаNuvarande inbyggda system kräver en mängd olika program och verktyg för att stödja dess utveckling. Dessutom är de flesta av dessa programvara och verktyg fristående applikationer. De är oanslutna och deras data kan vara inkonsistent och duplicerad. Detta medför ökad heterogenitet och ökar komplexiteten i utvecklingsmiljön. För att hantera denna situation används verktygsintegrationslösningar baserade på Länkad Data, eftersom de ger en skalbar och hållbar integrationslösning för olika tekniska verktyg. Olika system kan komma åt och dela data genom att följa den Länkad Data-baserade tjänsten Open Service for Lifecycle Collaboration (OSLC). OSLC använder TRS-protokollet (Tracked Resource Set) så att en server kan exponera en resursuppsättning och för att möjliggöra för en klient att upptäcka en resurs i resursuppsättningen. TRS-protokollet använder för tillfället pull-metoden så att klienten kan uppdatera sin data och synkronisera med servern. Denna metod är emellertid ineffektiv och tidskrävande. Vidare kan en högfrekvensdriven pull-metod införa en extra börda på nätverket och servern, medan lågfrekvensdriven ökar systemets latens (som ses av klienten). I det här examensprojektet implementerar vi en pushbaserad låg latenslösning för TRS-protokollet. Den teknik som används är Message Queue Telemetry Transport (MQTT). TRS-servern använder MQTT för att pusha uppdateringspatchen (som kallas ChangeEvent) till TRS-klienten. Därefter uppdaterar klienten dess innehåll enligt denna ChangeEvent. Vilket resulterar i att TRS-klienten synkroniseras med TRS-servern i realtid. Dessutom utvecklas en TRS-adapter för Atlassians JIRA som är ett välanvänt projekt och problemhanteringsverktyg. JIRA-TRS-adaptern tillhandahåller en TRS-leverantör med möjlighet att dela data via JIRA med annan programvara eller verktyg som använder TRS-protokollet. Dessutom utvecklade vi en simulator för att simulera verksamheten i JIRA under en tidsperiod (specifikt skapa, ändra och ta bort åtgärder rörande problem) och en validator för att kontrollera om data i TRS-klienten matchar data i JIRA. En utvärdering av det pushbaserade TRS-systemet visar en genomsnittlig synkroniseringsfördröjning på cirka 30 millisekunder. Detta är en stor förändring jämfört med det ursprungliga TRS-systemet som synkroniseras var 60:e sekund.
