Defining a framework model to determine total costs of managed desktops using ITIL best practices

In modern day organizations there are an increasing number of IT devices such as computers, mobile phones and printers. These devices can be located and maintained by using specialized IT management applications. Costs related to a single device accumulate from various sources and are normally categorized as direct costs like hardware costs and indirect costs such as labor costs. These costs can be saved in a configuration management database and presented to users using web based development tools such as ASP.NET. The overall costs of IT devices during their lifecycle can be ten times higher than the actual purchase price of the product and ability to define and reduce these costs can save organizations noticeable amount of money. This Master’s Thesis introduces the research field of IT management and defines a custom framework model based on Information Technology Infrastructure Library (ITIL) best practices which is designed to be implemented as part of an existing IT management application for defining and presenting IT costs.

Interaction between GIS and hydrologic model: a preliminary approach using ArcHydro Framework Data Model

In different regions of Brazil, population growth and economic development can degrade water quality, compromising watershed health and human supply. Because of its ability to combine spatial and temporal data in the same environment and to create water resources management (WRM) models, the Geographical Information System (GIS) is a powerful tool for managing water resources, preventing floods and estimating water supply. This paper discusses the integration between GIS and hydrological models and presents a case study relating to the upper section of the Paraíba do Sul Basin (Sao Paulo State portion), situated in the Southeast of Brazil. The case study presented in this paper has a database suitable for the basin's dimensions, including digitized topographic maps at a 50,000 scale. From an ArcGIS®/ArcHydro Framework Data Model, a geometric network was created to produce different raster products. This first grid derived from the digital elevation model grid (DEM) is the flow direction map followed by flow accumulation, stream and catchment maps. The next steps in this research are to include the different multipurpose reservoirs situated along the Paraíba do Sul River and to incorporate rainfall time series data in ArcHydro to build a hydrologic data model within a GIS environment in order to produce a comprehensive spatial-temporal model.

FRAMEWORK SYNTHESIS FOR SYMBOLIC EXECUTION OF EVENT-DRIVEN FRAMEWORKS

Symbolic execution is a powerful program analysis technique, but it is very challenging to apply to programs built using event-driven frameworks, such as Android. The main reason is that the framework code itself is too complex to symbolically execute. The standard solution is to manually create a framework model that is simpler and more amenable to symbolic execution. However, developing and maintaining such a model by hand is difficult and error-prone. We claim that we can leverage program synthesis to introduce a high-degree of automation to the process of framework modeling. To support this thesis, we present three pieces of work. First, we introduced SymDroid, a symbolic executor for Android. While Android apps are written in Java, they are compiled to Dalvik bytecode format. Instead of analyzing an app’s Java source, which may not be available, or decompiling from Dalvik back to Java, which requires significant engineering effort and introduces yet another source of potential bugs in an analysis, SymDroid works directly on Dalvik bytecode. Second, we introduced Pasket, a new system that takes a first step toward automatically generating Java framework models to support symbolic execution. Pasket takes as input the framework API and tutorial programs that exercise the framework. From these artifacts and Pasket's internal knowledge of design patterns, Pasket synthesizes an executable framework model by instantiating design patterns, such that the behavior of a synthesized model on the tutorial programs matches that of the original framework. Lastly, in order to scale program synthesis to framework models, we devised adaptive concretization, a novel program synthesis algorithm that combines the best of the two major synthesis strategies: symbolic search, i.e., using SAT or SMT solvers, and explicit search, e.g., stochastic enumeration of possible solutions. Adaptive concretization parallelizes multiple sub-synthesis problems by partially concretizing highly influential unknowns in the original synthesis problem. Thanks to adaptive concretization, Pasket can generate a large-scale model, e.g., thousands lines of code. In addition, we have used an Android model synthesized by Pasket and found that the model is sufficient to allow SymDroid to execute a range of apps.

Cultura e desempenho nas organizações de economia social: um estudo em cooperativas

Este estudo tem como objetivo compreender a relação existente entre a cultura organizacional e o desempenho nas organizações de economia social, em particular nas cooperativas. A pertinência do objeto de estudo reside no facto de a economia social, em particular as cooperativas, ser reconhecidamente um fenómeno secular, tendo expressão na quase totalidade dos países do mundo, o que tem contribuído para o seu reconhecimento jurídico e político. A crescente importância que este setor tem adquirido nos diferentes países revela o seu potencial enquanto agente empregador e enquanto alternativa às formas organizacionais e gestionárias do sistema capitalista em vigor. Também, o cooperativismo representa um papel fundamental a nível da economia social, por ser um imprescindível ator da coesão social, promovendo a renovação da economia e sociedade, contribuindo para a criação de novas esperanças e oportunidades para as comunidades e os seus cidadãos. Por outro lado, no mundo globalizado em que se vive ocorrem mudanças que despertam a reavaliação de premissas culturais. Nesse sentido, a cultura organizacional é considerada um fator de grande importância para o bom desempenho das organizações em geral (Campos, Rédua & Alvareli, 2011). Para a recolha de dados, utilizou-se o questionário, tendo por base o Modelo dos Valores Contrastantes de Quinn & Rohbaugh (1983) para a cultura e, para o desempenho, recorreu-se ao Modelo de Análise de Medição do desempenho nas OES de Carvalho (2005) e questionário para medir a satisfação no trabalho.Os resultados contribuíram para sugerir linhas orientadoras para o aprofundamento da temática. Não foi encontrado um perfil cultural que esteja mais relacionado com o melhor desempenho das cooperativas. Neste trabalho, saiu evidenciado que: vários tipos de cultura podem ser importantes para a obtenção de bons desempenhos nas cooperativas, havendo maior predominância para as culturas de Clã, Adocracia e Mercado e menos predominância para a cultura de Hierarquia. No âmbito das cooperativas deste estudo, a cultura Hierarquia, percecionada como não predominante parece coocorre com o melhor desempenho. Realçando o facto de que, mesmo nas cooperativas em que não há procedimentos estruturados é possível ter um bom desempenho.

Management of Nitrogen Oxides Reduction Project in a Cement Plant

The main aim of this study was to develop the project management framework model which would serve as the new model to follow for upcoming projects at the Lappeenranta cement plant. The other goal was to execute the SNCR (selective non catalytic reduction) project successfully so that the nitrogen oxides emissions are below the stated emission limit when the new emission limit comes into effect beginning in July, 2008. Nitrogen oxides, project management aspects, SNCR and the invested system are explained in the theory part. In the practical part of the study, the SNCR project in the Lappeenranta cement plant was executed and the findings were documented. In order to reach the aim of this study, a framework of project management was made. The framework is based on the executed SNCR project, previous projects in the cement plant and on the available literature relating to the subject matter. The developed project turned out to be successful.

Development of Collaborative Product Structure Management

The purpose of this thesis is to develop an environment or network that enables effective collaborative product structure management among stakeholders in each unit, throughout the entire product lifecycle and product data management. This thesis uses framework models as an approach to the problem. Framework model methods for development of collaborative product structure management are proposed in this study, there are three unique models depicted to support collaborative product structure management: organization model, process model and product model. In the organization model, the formation of product data management system (eDSTAT) key user network is specified. In the process model, development is based on the case company’s product development matrix. In the product model framework, product model management, product knowledge management and design knowledge management are defined as development tools and collaboration is based on web-based product structure management. Collaborative management is executed using all these approaches. A case study from an actual project at the case company is presented as an implementation; this is to verify the models’ applicability. A computer assisted design tool and the web-based product structure manager, have been used as tools of this collaboration with the support of the key user. The current PDM system, eDSTAT, is used as a piloting case for key user role. The result of this development is that the role of key user as a collaboration channel is defined and established. The key user is able to provide one on one support for the elevator projects. Also the management activities are improved through the application of process workflow by following criteria for each project milestone. The development shows effectiveness of product structure management in product lifecycle, improved production process by eliminating barriers (e.g. improvement of two-way communication) during design phase and production phase. The key user role is applicable on a global scale in the company.

Une perspective wébérienne sur l'influence du droit dans le contexte du divorce selon les pratiques des avocats et des médiateurs

Dans cette thèse de sociologie du droit, nous étudions l'influence du droit de l'État sur les sujets de droit. Notre hypothèse générale est que les intermédiaires du droit de l'État contribuent de façon importante à façonner le« rapport au droit» des sujets de droit. C'est-à-dire qu'ils auraient une incidence sur la construction de la relation d'influence du droit sur ces acteurs sociaux et, par là, un effet marqué sur la « légitimité empirique » du droit. Par leurs pratiques professionnelles les intermédiaires du droit auraient une incidence notable, quoique non exclusive, sur les formes concrètes de «rapports au droit» des sujets de droit. Dans l'étude de ce phénomène, nous comparons empiriquement les liens existant entre différents « rapports au droit » des sujets de droit et un droit caractérisé par une rationalité juridique fort différente selon qu'il aurait été porté par un avocat ou un médiateur. Ces deux groupes de professionnels sont les intermédiaires du droit qui font 1’objet de notre observation, laquelle n'est ni générale, ni globale, mais spécifique au divorce, géographiquement localisée à Montréal et historiquement située au début des années 1990. L'intérêt de cette période pour une étude de l'influence du droit sur les sujets de droit est qu'elle constitue un moment unique de l'histoire à Montréal. À cette époque, les différences entre les pratiques professionnelles des avocats et des médiateurs auraient été les plus extrêmes, ce qui favorise un travail de comparaison d'autant plus éclairant. En effet, au début des années 1990, après une dizaine d'années d'expérience, le Service de médiation à la famille de Montréal avait réussi à assurer une solide pratique professionnelle. Par ailleurs, la pratique professionnelle des avocats dans le domaine du divorce était déjà fort « modernisée », mais elle demeurait encore très peu influencée par la médiation familiale. Puisque le « rapport au droit » des personnes qui ont consulté ces intermédiaires du droit en vue de leur divorce est au cœur de 1 'étude, c'est auprès d'eux que nous avons réalisé des entretiens, et c'est l'analyse de ces entretiens qui permet de comprendre leur « rapport au droit». La sociologie de Max Weber est la perspective scientifique dans laquelle nous avons inscrit notre recherche. Une telle ambition exigeait que nous ne restions pas confinée aux seuls concepts les plus populaires. Par conséquent, une partie importante de cette thèse est consacrée à une présentation substantielle de la sociologie wébérienne. Sur cette base, nous avons construit notre stratégie d'enquête et nos instruments d'analyse idéal typiques. Non seulement il n'y a pas, chez Weber, de théorie systémique générale composée de lois explicatives des relations sociales, mais il n'y a pas non plus de modèle de cadre d'analyse particulier préfabriqué qui serait constitué comme un «prêt-à-porter» applicable en vue de réaliser des recherches empiriques, que ce soit dans le domaine du droit ou dans n'importe quel autre domaine d'activité humaine. En revanche, la sociologie wébérienne fournit plusieurs séries de repères conceptuels. Ils permettent d'organiser la recherche empirique sans jamais limiter les objets d'enquêtes possibles, ni l'imagination du chercheur, en autant que celui-ci a pour but de comprendre l'action sociale en l'interprétant et, par-là, de l'expliquer causalement dans son déroulement et ses effets. C'est là le projet de connaissance que Weber désigne par « sociologie ». Il vise ce projet de connaissance, non pas de manière générale et globale, mais toujours de manière particulière selon les domaines d'activité, les lieux, les époques, les sphères de valeurs, etc. Dans cette thèse, nous proposons un cadre d'analyse qui peut servir à poser et à approfondir toutes sortes de questions sur le droit et son influence, sans jamais qu'il soit considéré comme un système de lois à la manière du droit positif. Ce cadre d'analyse vise à appréhender le droit comme une sorte de relation sociale que l'on peut comprendre sociologiquement en considérant, notamment, les représentations juridiques des différentes catégories d'acteurs sociaux. C'est là la première, non pas la seule, condition à rencontrer en vue de respecter les exigences de la connaissance empirique du droit parce que le « droit empirique » ne se trouve pas dans la règle de droit positif. Il se trouve là où il est « porté » par des êtres humains et, en particulier, par des groupes d'humains qui détiennent une importante dose d'influence sociale. Nous souhaitons que cette étude, grâce à 1 'immense apport de la sociologie de Max Weber, contribue à la compréhension sociologique d'un aspect du « droit empirique» de l’État contemporain.

La victimisation en milieu scolaire : une analyse des facteurs individuels, contextuels et environnementaux

Contexte et objectifs. Ce mémoire propose un modèle conceptuel écologique afin de mieux comprendre la violence dans les écoles. Les objectifs de cette recherche sont de ; 1) estimer l’effet des facteurs individuels, contextuels et environnementaux sur le risque de victimisation, 2) vérifier la présence d’interactions entre les différents facteurs. Méthodologie. Les élèves de 16 écoles primaires de la grande région métropolitaine de Montréal ont pris part à un sondage auto-révélé en lien avec différentes dimensions liées à la victimisation en milieu scolaire. Des analyses descriptives ont été menées, dans un premier temps, pour dresser le portrait de la violence en milieu scolaire. Dans un second temps, l’emploi d’un modèle linéaire hiérarchique généralisé (MLHG) a permis d’estimer les effets de variables propres à l’individu, au contexte et à l’environnement sur le risque de victimisation. Résultats. Les résultats aux analyses multiniveaux montrent que des variables individuelles, contextuelles et environnementales influent sur la probabilité d’être victime de violence verbale, physique et dans les médias sociaux. Ainsi, les élèves les plus délinquants sont aussi ceux qui rapportent le plus d’antécédents de victimisation. Toutefois, ces résultats ne sont pas entièrement imputables aux caractéristiques des individus. Le risque de victimisation est atténué lorsque les « gardiens » interviennent pour mettre un terme au conflit et que les victimes se défendent. Enfin, le risque de victimisation est moins élevé dans les écoles où il y a un grand nombre d’élèves. Interprétation. Les résultats suggèrent que plusieurs facteurs qui ne sont pas liés aux victimes et aux délinquants permettent de mieux comprendre le processus de victimisation en milieu scolaire. Le rôle des gardiens de même que la taille des écoles sont des éléments centraux à la compréhension du passage à l’acte.

Autoavaliação de um agrupamento : um percurso de melhoria da qualidade de gestão e do serviço educativo da escola

Com o propósito de acompanhar a mudança da sociedade, em Portugal decorre a implementação de várias reformas entre as quais a da Administração Pública. Melhorar o serviço educativo prestado pelas escolas é condição essencial para o aumento da qualificação dos alunos. A Avaliação e a Auto Avaliação (AA) do desempenho da escola tornam-se cada vez mais importantes no sentido de acompanhar e garantir a evolução e o progresso do sistema educativo. Desta forma, torna-se imprescindível uma reflexão sobre os procedimentos desenvolvidos que visam suprir as necessidades das escolas. Este projeto de investigação, no âmbito do Mestrado em Ciências da Educação, especialização em Administração Escolar, tem como finalidade dar o seu contributo para esse debate, através da apresentação e discussão dos resultados de dois ciclos avaliativos, tendo sido aplicado, o modelo CAF (Common Assessment Framework). Neste sentido, pretendeu-se averiguar de que forma a AA (Auto Avaliação) contribui para o processo global de gestão da escola. Fazendo recurso à metodologia de estudo de caso, num Agrupamento de Escolas no interior do país, utilizou-se o paradigma qualitativo para a recolha de dados. Pela análise dos dados foi possível concluir que a aplicação do primeiro ciclo de avaliação, através do desenvolvimento de processos de melhoria da qualidade de serviço prestado, influenciou o segundo ciclo avaliativo. Esta influência foi evidente na melhoria dos planos de ação para colmatar pontos negativos detetados no ciclo avaliativo anterior contribuindo, consequentemente, para a melhoria do processo de gestão da escola. Desta forma, a experiência adquirida, as alterações introduzidas, a convição dos órgãos de gestão da escola e de quase todas as pessoas que nela exercem a sua atividade permitem concluir que é imprescindível a autorregulação e que a mesma proporcionou benefícios que levaram à melhoria da qualidade de gestão da escola.

Het effect van formele en informele feedback op het innovatievermogen van organisaties

Little attention in literature so far has been given to the impact of feedback on organizational development and change. As well as the impact of feedback on the innovation power of organizations. The capacity of innovation of organizations however may be seen as a crucial capacity of organizations to survive in competitive markets. Prior studies towards the impacts of feedback have more often analyzed formal and informal feedback separately, other than analyzing them together in one study. This master thesis develops and explores a model to assess the possible impact of both formal and informal feedback on the capacity of innovation within organizations. The master thesis is the closing assignment of a Master Study Management at the Open Universiteit Nederland. The general question of the single-case study is: What is the impact of formal and informal feedback on the capacity of innovation of companies? The explored model in the study is a combination of the model of Lawson and Samson (2001) about the capacity of innovation and the framework model of Pitkänen and Lukka (2011) about formal and informal feedback. The single-case study is performed at Yellowbrick, a Dutch company which offers consumers an online parking service, suitable for the use on smartphones. The single-case study is performed twofold by semi-structured interviews and a survey. Although conclusions may not be generalized, because of the limitations of the study and the particularly small investigated group, some findings may be suitable for further investigation. In the study was found that feedback has an impact on the capacity of innovation. Formal feedback scored higher than informal feedback when asked about the impact on the capacity of innovation. The study also found multiple ‘new’ kinds of feedback used by organizations, other than the more ‘traditional’ forms of feedback, such as team meetings and bilateral meetings. Further on was analyzed that when employees find themselves more involved in the process of an innovation, they also seem to score the organization higher on the capacity of this innovation.
