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

Potencialidades de cultivo de macroalgas no litoral do Rio Grande do Norte (NE, Brasil): uma perspectiva de integração de dados ambientais em sistemas de informação geográfica (SIG)

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

Sistemas de informação geográfica e análise espacial de dados como ferramentas para determinação de agregação espacial de doenças: a hanseníase como modelo

This work demonstrates the importance of using tools used in geographic information systems (GIS) and spatial data analysis (SDA) for the study of infectious diseases. Analysis methods were used to describe more fully the spatial distribution of a particular disease by incorporating the geographical element in the analysis. In Chapter 1, we report the historical evolution of these techniques in the field of human health and use Hansen s disease (leprosy) in Rio Grande do Norte as an example. In Chapter 2, we introduced a few basic theoretical concepts on the methodology and classified the types of spatial data commonly treated. Chapters 3 and 4 defined and demonstrated the use of the two most important techniques for analysis of health data, which are data point processes and data area. We modelled the case distribution of Hansen s disease in the city of Mossoró - RN. In the analysis, we used R scripts and made available routines and analitical procedures developed by the author. This approach can be easily used by researchers in several areas. As practical results, major risk areas in Mossoró leprosy were detected, and its association with the socioeconomic profile of the population at risk was found. Moreover, it is clearly shown that his approach could be of great help to be used continuously in data analysis and processing, allowing the development of new strategies to work might increase the use of such techniques in data analysis in health care

Avaliação da Suscetibilidade a Movimentos de Massa no Município de Várzea Paulista (SP) Utilizando os Sistemas de Informação Geográfica

O objetivo deste trabalho foi identificar e mapear áreas suscetíveis a movimentos de massa, por meio das geotecnologias, no município de Várzea Paulista (SP). Para o propósito, foram utilizados os mapas de declividade, geológico, geomorfológico e de uso e ocupação da terra, que foram sobrepostos por meio da Análise Multicritério no SIG ArcGIS. Cada tema recebeu seu peso de influência para deflagração de tais processos e como resultado final foi obtido o mapa de suscetibilidade a movimentos de massa do município em questão. Paralelamente foi elaborado o estudo da orientação de vertentes, para determinação daquelas que apresentam maiores riscos em comparação com os dados coletados em campo. Constatou-se que existem muitas áreas ocupadas dentro do município que carecem de monitoramento do Poder Público, principalmente nos meses chuvosos, pois se encontram em locais frágeis do ponto de vista geológico-geomorfológico.

Aplicação dos Sistemas de Informação Geográfica nas energias renováveis: o potencial da energia solar na ilha de São Vicente – Cabo Verde

Informação Geográfica (SIG) ao estudo das energias renováveis, tendo como caso avaliar o potencial solar na ilha de São Vicente do arquipélago de Cabo Verde. A energia do sol é a principal fonte de energia renovável, e está disponível em quase todas as regiões do planeta. Quantificar o potencial energético solar de um lugar ou região é indispensável, para avaliar as potencialidades de produção de energia fotovoltaica. Outro fator importante prende-se com ordenamento territorial associado à exploração desses recursos energéticos, pelo que devem ser avaliadas as condições técnicas, ambientais e económicas, quando se pretende instalar parques para a produção de energia fotovoltaica. Assim, neste trabalho foram aplicadas as ferramentas SIG, para quantificar a radiação solar mensal e anual da ilha de São Vicente, arquipélago de Cabo Verde, através do modelo Solar Analyst. Numa segunda fase, aplicou-se a técnica de análise multicritério em combinação com os SIGs para definir as áreas mais favoráveis para a instalação de parques de produção de energia elétrica a partir da energia solar. Para o cálculo da radiação solar na ilha de São de Vicente, utilizou-se o modelo digital de terreno (MDT) e a latitude da ilha como parâmetros de entrada ao modelo. Para a análise multicritério definiram-se um conjunto de critérios que devem ser considerados na implementação de parques solares, nomeadamente, a disponibilidade de radiação solar existente na área, a distância à rede de transporte de energia elétrica e à rede viária, o declive do terreno, o uso e ocupação do solo e a proximidade às linhas de água. Para auxiliar na atribuição dos pesos aos critérios utilizados na análise aplicou-se a método Analytic Hierarchy Process (AHP). As áreas resultantes do processo da análise multicritério, foram confrontadas com a Carta de Condicionantes do esquema regional de ordenamento da ilha de São Vicente, aferindo a conformidade das propostas e reajustes subsequentes, de modo a obter os resultados finais.

O Contributo dos Sistemas de Informação para a Eficácia da Liderança e para a Mudança do Comportamento Organizacional

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.
