The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN

The Information Technology (IT) is increasing his applicability to business, both private and public companies. It is necessary the adequate use of the new technologies and get cooperation and technology acceptance of the system. People tend to resist to the changes, contributing so that the technology is rejected or even it is not recognized as promoting of the changes. This study is relevant and aim to evaluate the impacts of new technologies, considering their users as fundamental factors in the change process. The survey analyzed the advantages and the barriers of the system use in three federal special judicial of Rio Grande do Norte, with data collected in May of 2007, through the application of questionnaires to thirty eight users of the virtual system CRETA. The users' perception was evaluated, under the optics of five variables: efficiency, image, agility, ease of use and quality. Starting from the obtained results, it was evidenced that the implementation of the system felt accordingly the expected and it reached the objectives intended that were: the velocity and efficiency in the path of the lawsuits, larger productivity, resulting in a better quality of the final work introduced to the citizen and proportionate an improvement in the organizational image of the judiciary power

A tecnologia democratizou o acesso à informação, a competitividade das empresas do século XXI cada dia mais se baseia em conhecimento e as gestões das ações da administração pública ampliam a busca por um sistema coordenado, preocupado com a gestão eficiente que possa maximizar o retorno social, levando-se em consideração os direitos humanos fundamentais na esfera das relações informáticas. A administração pública avança em seus processos de aproximação com a sociedade, pautando-se cada dia mais nos benefícios proporcionados pela evolução dos processos de Tecnologia da Informação e Comunicação (TICs), os serviços disponibilizados pelo governo eletrônico vêm ganhando espaço na vida da população (G2C). Diante desta evolução os aspectos de acessibilidade são uma diretriz clara e o Decreto Lei nº 5.296, define como barreiras nas comunicações e informações “qualquer entrave ou obstáculo que dificulte ou impossibilite a expressão ou o recebimento de mensagens por intermédio dos dispositivos, meios ou sistemas de comunicação, sejam ou não de massa, bem como aqueles que dificultem ou impossibilitem o acesso à informação; “ (BRASIL 2004). Após mais de 10 anos de promulgação da lei de Acessibilidade, é evidente que a qualidade dos serviços prestados pelo governo eletrônico só será efetiva se o instrumento de comunicação utilizado for realmente o facilitador da interação entre o cidadão e o governo, sem distinção do público utilizador de tais serviços. Esta pesquisa pretende avaliar aspectos de acessibilidade dos principais portais públicos brasileiros, sob a ótica de pessoas com limitação visual, avaliando ações, atividades e iniciativas conforme a abordagem da Engenharia Semiótica em prol das tecnologias assistivas de inclusão, permitindo a recomendação de requisitos para a construção de Portais Web Acessíveis em Multiplataforma, favorecendo a inclusão digital e maior independência dos mesmos.

O Programa de Triagem Neonatal de Minas Gerais (PTN-MG), cuja rede estadual é composta por mais de três mil Unidades Básica de Saúde (UBS), é uma estratégia de diagnóstico precoce do Sistema Único de Saúde (SUS) de extrema importância para a população. Para alinhar o sistema de informação do Programa à essa premissa, este estudo apresenta o seguinte problema: Quais são os fatores determinantes do uso de um sistema de informação do PTN-MG e quais são as relações entre eles? Buscou-se a partir de um estudo no âmbito do SUS em Minas Gerais, com a aplicação de um survey a todas as Unidades Básicas de Saúde do Estado que utilizam o sistema de informação, desenvolver um módulo de sistemas de informação inteligente para toda rede Estadual; avaliar as percepções dos usuários baseando-se na integração dos modelos TAM e TTF (KLOPPING; MCKINNEY, 2004) com variáveis de Índice de Desenvolvimento Humano dos municípios e a capacidade de coleta das UBS; analisar os fatores determinantes do uso do SI e suas respectivas relações. O modelo continha 16 hipóteses, sendo que 06 foram confirmadas a partir de um estudo realizado por modelagem de equações estruturais. Os principais resultados indicaram que a maioria dos usuários concordou que o sistema de informação é útil, fácil de usar e ajustável às suas tarefas. O estudo confirma também que os modelos TAM e TTF se completam, pois apresentam várias relações significativas entre os seus constructos. Outro achado importante, foi a relação inversa encontrada entre o IDHM do município e a percepção de utilidade do modelo TAM. Entende-se que o estudo cumpriu com o objetivo proposto e ainda gera novas expectativas futuras como: aplicação do modelo em outras realidades e a inclusão de outros constructos sociais para verificação de possíveis relações com o modelo TAM/TTF.

O presente trabalho debruça-se sobre os constructos da liderança e do comportamento de auto-eficácia da liderança nas organizações. Reflecte-se sobre a importância dos sistemas de informação no clima organizacional, com efeitos sobre a eficácia na liderança. Trata-se de uma perspetiva pertinente na conjuntura organizacional atual, dado que incide sobre valores patrimoniais intangíveis que, quando dinamizados, dão suporte à performance organizacional. A nossa preocupação central é a auto-eficácia. Através dela pretende-se melhorar a eficiência organizacional, porque minimiza prejuízos e desperdícios. Também se relaciona a eficácia com o desempenho da liderança organizacional e com o capital ‘confiança’. Dessa forma, os novos caminhos passam por auscultar a percepção dos colaboradores sobre a importância da cultura organizacional face ao desempenho e à eficácia de longo prazo na organização. Com a presente reflexão, evidencia-se que a espiritualidade no local de trabalho é um factor de apoio ao desenvolvimento holístico dos colaboradores. Fica sublinhado que é fundamental que os líderes tenham noção e consciência de “si” e dos seus papéis, e como estes se reflectem no seu comportamento quotidiano na organização. O estudo assenta num trabalho de campo, elaborado numa organização intensiva em informação e que presta serviços de consultoria e informática. Os resultados apurados tentam dizer que, globalmente, no estudo longitudinal das hetero-percepções dos gestores directos e indirectos, o gap cultural diminuiu em todas as dimensões relativas às competências dos papéis, sendo vital destacar o quadrante designado por Apoio. As hetero-percepções dos gestores directos demonstram que o menor gap cultural mantem-se no quadrante de Objectivos Racionais e Competir no modelo de CVF, caracterizado por uma cultura de mercado, e relacionado com a fase da Combinação no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conversão do conhecimento explícito para o explícito). Enquanto que o maior gap cultural reside no quadrante Apoio e Colaborar no modelo CVF, relacionado com a fase da Socialização no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conhecimento tácito para tácito). Como o gap cultural diminuiu em todas as dimensões, pode realçar uma melhoria das percepções do desempenho organizacional. Contudo, um resultado inesperado está associado ao quadrante Apoio com a cultura de clã, uma vez que são os gestores indirectos na empresa em estudo que fomentam esta cultura, e não os gestores directos, conforme seria desejável. Um resultado favorável para o estudo da auto-eficácia da liderança demonstra que as médias são mais elevadas para atributos de Gestão e Resolução de Problemas. Os resultados que não corresponderam às expectativas iniciais estão associados às médias baixas relativamente aos atributos Sociais/de Comunicação, o que pode ser uma debilidade porque seria desejável que a equipa de gestão tivesse maior sensibilidade perante os capitais sociais, emocionais e espirituais, os quais estão relacionados com estes atributos.

Universities are institutions that generate and manipulate large amounts of data as a result of the multiple functions they perform, of the amount of involved professionals and students they attend. Information gathered from these data is used, for example, for operational activities and to support decision-making by managers. To assist managers in accomplishing their tasks, the Information Systems (IS) are presented as tools that offer features aiming to improve the performance of its users, assist with routine tasks and provide support to decision-making. The purpose of this research is to evaluate the influence of the users features and of the task in the success of IS. The study is of a descriptive-exploratory nature, therefore, the constructs used to define the conceptual model of the research are known and previously validated. However, individual features of users and of the task are IS success antecedents. In order to test the influence of these antecedents, it was developed a decision support IS that uses the Multicriteria Decision Aid Constructivist (MCDA-C) methodology with the participation and involvement of users. The sample consisted of managers and former managers of UTFPR Campus Pato Branco who work or have worked in teaching activities, research, extension and management. For data collection an experiment was conducted in the computer lab of the Campus Pato Branco in order to verify the hypotheses of the research. The experiment consisted of performing a distribution task of teaching positions between the academic departments using the IS developed. The task involved decision-making related to management activities. The data that fed the system used were real, from the Campus itself. A questionnaire was answered by the participants of the experiment in order to obtain data to verify the research hypotheses. The results obtained from the data analysis partially confirmed the influence of the individual features in IS success and fully confirmed the influence of task features. The data collected failed to support significant ratio between the individual features and the individual impact. For many of the participants the first contact with the IS was during the experiment, which indicates the lack of experience with the system. Regarding the success of IS, the data revealed that there is no significance in the relationship between Information Quality (IQ) and Individual Impact (II). It is noteworthy that the IS used in the experiment is to support decision-making and the information provided by this system are strictly quantitative, which may have caused some conflict in the analysis of the criteria involved in the decision-making process. This is because the criteria of teaching, research, extension and management are interconnected such that one reflects on another. Thus, the opinion of the managers does not depend exclusively on quantitative data, but also of knowledge and value judgment that each manager has about the problem to be solved.

Since centuries ago, the Asians use seaweed as an important source of feeding and are their greatest world-wide consumers. The migration of these peoples for other countries, made the demand for seaweed to increase. This increasing demand prompted an industry with annual values of around US$ 6 billion. The algal biomass used for the industry is collected in natural reservoirs or cultivated. The market necessity for products of the seaweed base promotes an unsustainable exploration of the natural banks, compromising its associated biological balance. In this context, seaweed culture appears as a viable alternative to prevent the depletion of these natural supplies. Geographic Information Systems (GIS) provide space and produce information that can facilitate the evaluation of important physical and socio-economic characteristics for the planning of seaweed culture. This objective of this study is to identify potential coastal areas for seaweed culture in the state of Rio Grande do Norte, from the integration of social-environmental data in the SIG. In order to achieve this objective, a geo-referred database composed of geographical maps, nautical maps and orbital digital images was assembled; and a bank of attributes including physical and oceanographical variables (winds, chains, bathymetry, operational distance from the culture) and social and environmental factors (main income, experience with seaweed harvesting, demographic density, proximity of the sheltered coast and distance of the banks) was produced. In the modeling of the data, the integration of the space database with the bank of attributes for the attainment of the map of potentiality of seaweed culture was carried out. Of a total of 2,011 ha analyzed by the GIS for the culture of seaweed, around 34% or 682 ha were indicated as high potential, 55% or 1,101 ha as medium potential, and 11% or 228 ha as low potential. The good indices of potentiality obtained in the localities studied demonstrate that there are adequate conditions for the installation of seaweed culture in the state of Rio Grande do Norte

Esta dissertação apresenta uma arquitectura interoperável que permite lidar com a obtenção, manipulação, processamento e análise de informação geográfica. A aplicação 30, implementada como parte da arquitectura, para além de permitir a visualização e manipulação de dados dentro de um ambiente 30, oferece métodos que permitem descobrir, aceder e usar geo-processos, disponíveis através de serviços Web. A interacção com o utilizador é também feita através uma abordagem que quebra a típica complexidade que a maioria dos Sistemas de Informação Geográfica apresenta. O recurso à programação visual reduz a complexidade do sistema, e permite aos operadores tirar proveito da localização e de uma abstracção de um processo complexo, onde as unidades de processamento são representadas no terreno através de componentes 30 que podem ser directamente manipuladas e ligadas de modo a criar encandeamentos complexos de processos. Estes processos podem também ser criados visualmente e disponibilizados online. ABSTRACT; This thesis presents an interoperable architecture mainly designed for manipulation, processing and geographical information analysis. The three-dimensional interface, implemented as part of the architecture, besides allowing the visualization and manipulation of spatial data within a 30 environment, offers methods for discovering, accessing and using geo-processes, available through Web Services. Furthermore, the user interaction is done through an approach that breaks the typical complexity of most Geographic information Systems. This simplicity is in general archived through a visual programming approach that allows operators to take advantage of location, and use processes through abstract representations. Thus, processing units are represented on the terrain through 30 components, which can be directly manipulated and linked to create complex process chains. New processes can also be visually created and deployed online.

Num mundo em que cada vez mais se recorre aos sistemas de informação para suporte às actividades das empresas e instituições a necessidade de troca de informação, de participação em processos conjuntos, de partilha de dados assume uma importância vital nas organizações. Como resposta à crescente necessidade de integração dos sistemas de informação, começaram a surgir um sem número de soluções e conceitos que têm como objectivo dar resposta a esta problemática. Assim, e de forma a contribuir como um elemento facilitador na interoperabilidade e integração de sistemas, este trabalho tem como propósito a construção de uma framework de integração conceptual, framework esta construída através de uma sistematização de conceitos, que embora conhecidos, existem de uma forma dispersa. Potencia-se assim como uma ferramenta orientadora, principalmente para aqueles que não possuem os conhecimentos adequados ou suficientes para colocar um modelo de integração em prática de forma consciente. Como tal, será uma ferramenta indispensável para dar a conhecer soluções, etapas, vantagens, desvantagens, diferentes modelos e será, sem dúvida, uma mais-valia em futuras integrações. ABSTRACT; ln a world where the use of information systems increases daily, the growing demand for data exchange, data sharing and processes integration assumes a vital role in organizations life. ln order to answer to the growing needs of information systems integration, many solutions and concepts start to emerge with the goal to answer those needs. ln a way to contribute to the information systems interoperability and integration, this thesis presents an conceptual integration systems framework built by using a set of well known concepts, which exist in a sparse way. This conceptual framework appears mainly for those that for some reason don’t have sufficient knowledge to implement integration model in a sensible way. Such framework will be the perfect tool to provide the knowledge about solutions, stages, advantages, disadvantages and existent models, being a tool to consider in future integrations.
