Antecedentes da efetividade dos investimentos em tecnologia e sistemas da informação

Esta pesquisa desenvolveu e aplicou um procedimento para a avaliação da efetividade de investimentos em Sistemas e Tecnologia da Informação, no nível das organizações, baseado no Modelo de Análise da efetividade de investimentos em sistemas e Tecnologia da Informação no nível da Firma - MATIF, conforme proposto inicialmente em artigo publicado nos Proceedings of the Tenth Americas Conference on Information Systems - AMCIS, New York (SANCHEZ e ALBERTIN, 2004). A contribuição fundamental do MATIF consiste de oferecer uma sistematização dos elementos econômicos envolvidos na análise de potencial de geração de valor para os negócios de investimentos em sistemas e tecnologia da informação, partindo da tese da Ex-ante Inneficiency Economic Hipotesis – EEIH. A EEIH indica que haverá valor econômico potencialmente gerado pelo investimento em TI se houver, previamente, uma situação econômica de ineficiência a ser resolvida pelo sistema conseqüente a esse investimento. A pesquisa tratou de verificar a hipótese do EEIH em um estudo de caso incorporado conduzido em três destacadas instituições financeiras do Brasil. Apresentou, como resultado, o desenvolvimento conceitual sobre os principais aspectos que podem permitir às organizações avaliarem se seus investimentos em sistemas de informação terão potencial de apresentar resultados. A pesquisa contribui para o campo de administração e para a prática gerencial por meio da apresentação do modelo MATIF desenvolvido e pela verificação de sua aplicabilidade no que se refere à capacidade de produção de uma análise ex-ante de efetividade de investimentos em sistemas de informação.

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
