Esta pesquisa tem como objetivo principal investigar a possível contribuição do modelo de organização de Karl Weick (1973) para a compreensão teórica do processo de entendimento compartilhado entre usuários e desenvolvedores sobre as demandas de desenvolvimento de sistemas de informação. A pesquisa se justifica pela atualidade do tema e pela relevância da abordagem. Embora existam muitas pesquisas sobre o tema, o problema de comunicação (misunderstanding) sobre as demandas permanece atual nas empresas. Além disso, as pesquisas existentes adotam abordagens preponderantemente pragmáticas e deixam uma lacuna em relação à adoção de abordagens mais compreensivas. Dentre as teorias adotadas nos estudos organizacionais, o modelo de organização como processo, de Karl Weick (1973), pareceu oferecer potencial explicativo para processos dinâmicos como o entendimento compartilhado sobre as demandas. Esse modelo foi adotado como base conceitual do trabalho, sendo estendido na forma de proposições que expressam sua possível aplicação ao objeto de pesquisa. Essa aplicação foi investigada com uso do método Estudo de Caso único em profundidade com múltiplas fontes de coleta de dados (entrevistas individuais, observação participante e consulta documental) e múltiplas unidades de análise (dez projetos de desenvolvimento ou alteração de sistemas de informação). Os resultados da pesquisa foram provenientes da técnica de Análise de Conteúdo, utilizada para a descrição analítica de cada projeto, a identificação de indícios dos conceitos do modelo teórico e a geração de categorias dos dados empíricos. Esse processo de análise permitiu a verificação da plausibilidade de cada proposição. Com base nessa análise, a consolidação feita por comparação e agrupamento dos projetos, por verificação das transições entre os elementos, e pela identificação de divergências entre o modelo teórico e os dados empíricos permitiu a investigação e o desenvolvimento de uma possível contribuição do modelo de Weick (1973) como alternativa para a compreensão teórica do objeto de pesquisa. Esse resultado também permitiu identificar outras diferentes perspectivas para novas pesquisas baseadas na abordagem adotada (como a perspectiva de serviços, de sensemaking e a de subculturas organizacionais), o que pode configurar uma contribuição acadêmica inovadora e relevante. / The present study aims to investigate the potential contribution of Weick’s organizing model (1973) to theoretical comprehension of the shared understanding process between users and developers about demands of information systems. The relevance of this issue rises from the existence of many other investigations about it and the remaining of the misunderstanding problem about demands in practice. A great deal of papers has approached this issue pragmatically, showing an opportunity to researches which adopt comprehensive approaches. One of the most studied organizational theories, namely Weick’s organizing model (1973), potentially offer an alternative point of view to this dynamic process and was adopted as the conceptual basis of this investigation. An extension or application of the model to the research object was developed in form of research propositions. An in-depth case-study was developed with multiple data sources (individual interviews, participant observation and documents consulting) and multiple analysis units (ten information systems development projects). Content Analysis techniques offered the results, including analytical descriptions of each project, identification of clues of model concepts and generation of categories from empirical data. This analytical process allows verifying plausibility of each theoretical proposition. A consolidation was done by comparing projects, verifying transitions among elements, identifying divergences between conceptual model and empirical data. This entire process made possible an investigation and the development of a potential contribution of Weick’s organizing model as an alternative mode for theoretical comprehension of this research object. These results also allow identifying other alternative perspectives for new investigations based on this approach (for example, perspectives of services, sensemaking and organizational subcultures), which can be seen as innovative and relevant academic contributions.

One of the most problems faced by the financial manager is to maintain a balance between resources and applications of short and long term. Working Capital Management appears as a tool to improve the profitability of the company without representing a loss in their ability to pay. This study aims to evaluate if the financial performance achieved by companies belonging to the Stock Exchange of Sao Paulo, from 1999 to 2008, has a dependent relationship with the companies liquidity, measured by Fleuriet´s Model. Also know as Dynamic Analysis Model, the Fleuriet s Model consists of an analysis technique of balance sheets that evaluates the liquidity perspective of operations. and to that end, the balance sheet accounts are reclassified. In this study, the variable Fleuriet s Model was measured by three ways: first just from the perspective of liquidity, with the measurement of the Treasury s Balance and Liquidity s Index; and then from the perspective of the model as a whole, being taken an ordinal scale represent the possible financial structures. In relation to the financial performance adopted as a measure of corporate profitability, the Return on Equity (ROE), and a measure of stock return, the Earnings per Share (EPS). The corporate data used in calculo of variables were collected from financial statements, while the macroeconomic variables were obtained from institutions such as the IPEA and the Central Bank. The data were analyzed with a technical of Panel Data. The results of the initial estimate for the population, indicated that relationship of dependence between the ROE and the Fleuriet s Model and between the LPA and the Fleuriet s Model. When market sector is considered, the Fleuriet s Model is significant and has the opposite pattern expected. For the metalworking and steel industry, the variable Fleuriet s Model significant was Treasury s Balance. Since the textile sector presented the Liquidity s Index as a variable Fleuriet s Model significant. Finally, we have that, although it has been found relationship between the economic and financial performance and the Fleuriet s Model, the estimated models had low explanatory power, making it difficult to generalize the results. / Um dos grandes problemas enfrentados pelo gestor financeiro está na manutenção de um equilíbrio entre recursos e aplicações de curto e longo prazo. A administração do Capital de Giro aparece como uma ferramenta capaz de melhorar a rentabilidade da empresa, sem que isso represente uma perda na sua capacidade de pagamento. Este estudo tem por objetivo avaliar se o desempenho econômico-financeiro obtido pelas empresas pertencentes à Bolsa de Valores de São Paulo, no período de 1999 a 2008, tem relação de dependência com a liquidez das mesmas, mensurada através do Modelo Fleuriet. Também conhecido como Modelo de Análise Dinâmica, o Modelo Fleuriet consiste em uma técnica de análise de balanços que avalia a liquidez pela perspectiva das operações, sendo que, para tal, as contas do balanço patrimonial são reclassificadas. Neste estudo, a variável Modelo Fleuriet foi representada por três medidas: primeiramente, apenas sob a ótica da liquidez, com a mensuração do Saldo de Tesouraria e do Índice de Liquidez; e, posteriormente, sob a ótica do modelo como um todo, sendo adotada uma escala ordinal, para representar as estruturas financeiras possíveis. Já em relação ao desempenho econômico-financeiro, adotou-se uma medida de rentabilidade corporativa, o Retorno sobre o Capital Próprio (ROE), e uma medida de retorno acionário, o Lucro por Ação (LPA). Os dados corporativos utilizados nos cálculos das variáveis foram coletados junto às demonstrações financeiras, enquanto que as variáveis macroeconômicas foram obtidas junto às instituições como o IPEA e o Banco Central. Os dados foram analisados sob a técnica de Dados em Painel. Os resultados da estimação inicial, para a população, indicaram a existência de relação de dependência entre o ROE e o Modelo Fleuriet e entre o LPA e o Modelo Fleuriet. Quando o setor de atuação é considerado, o Modelo Fleuriet mostra-se significativo e apresenta o comportamento inverso esperado. Para o setor de metalurgia e siderurgia, a variável do Modelo Fleuriet significativa foi o a Estrutura de Balanço. Já o setor têxtil apresentou o Índice de Liquidez como a variável do Modelo Fleuriet significativa. Por fim, tem-se que, embora tenha sido encontrada relação entre o desempenho econômico-financeiro e o Modelo Fleuriet, os modelos estimados apresentaram baixo poder de explicação, dificultando a generalização dos resultados.

Perfusion MRI can provide information about perfusion characteristics of the observed tissue, which makes it a widely applicable medical procedure. Measuring process of MRI is very time-consuming, and therefore, using classical reconstruction methods, we are often not able to obtain enough samples to accomplish the needed time and space resolution for perfusion analysis. That is why it is necessary to use compressed sensing, which allows reconstruction from under-sampled data by solving an optimization model. In this work, several models for reconstruction of an image sequence are verified on real and artificial data, along with multiple algorithms capable of solving these models. Among the optimization models used in this work are two L+S models with different regularization of the S component that are solved by Forward-Backward and Chambolle-Pock algorithm. The quality of reconstruction for various models was compared especially by their perfusion curves. In the last section, we explore possible modifications of the SASS model in order to increase quality of reconstruction and resistance to under sampling for the purpose of better adaptation for dynamic data.
