Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Crenças normativas e comportamentais e suas influências na intenção de adoção de um sistema de informação: um estudo na área de compras da UFPA

The study aims to identify the factors that influence the behavior intention to adopt an academic Information System (SIE), in an environment of mandatory use, applied in the procurement process at the Federal University of Pará (UFPA). For this, it was used a model of innovation adoption and technology acceptance (TAM), focused in attitudes and intentions regarding the behavior intention. The research was conducted a quantitative survey, through survey in a sample of 96 administrative staff of the researched institution. For data analysis, it was used structural equation modeling (SEM), using the partial least squares method (Partial Least Square PLS-PM). As to results, the constructs attitude and subjective norms were confirmed as strong predictors of behavioral intention in a pre-adoption stage. Despite the use of SIE is required, the perceived voluntariness also predicts the behavior intention. Regarding attitude, classical variables of TAM, like as ease of use and perceived usefulness, appear as the main influence of attitude towards the system. It is hoped that the results of this study may provide subsidies for more efficient management of the process of implementing systems and information technologies, particularly in public universities

A Tecnologia da informação como fator de competitividade em um apl: o caso da carcinicultura do RN

Este estudo aborda a utilização da tecnologia da informação de forma competitiva em um Arranjo Produtivo Local APL. Realizou-se no APL da carcinicultura no Estado do Rio Grande do Norte e teve por objetivo buscar a compreensão de como o uso da tecnologia da informação (TI) contribui para o aumento da competitividade na atividade do APL citado. APL pode ser conceituado como uma aliança entre organizações que possuem um projeto coletivo, para elevar a sua competitividade e participação no mercado. Para atingir este objetivo, foi realizada uma pesquisa descritiva, através da utilização de múltiplos casos selecionados dentre as empresas que compõem o APL da carcinicultura no RN. Os dados coletados foram analisados qualitativamente. Os resultados da pesquisa indicaram que as empresas percebem a importância do uso da TI, mas que, na prática, a sua utilização é limitada, principalmente em se tratando de Sistemas Integrados de Gestão e Comércio Eletrônico. Outro resultado encontrado foi que as empresas, embora façam parte do APL, ainda não colaboram entre si, seja através da troca de informações, ou através de Sistemas de Informação Interorganizacional. As principais recomendações diante destes resultados é que as empresas atuem ativamente para o fortalecimento do APL. No que se refere ao uso da TI faz-se necessário que elas invistam na aquisição de sistemas integrados de gestão e sistemas de informação interorganizacional para o melhor gerenciamento das informações ao longo da cadeia

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

Centro de Informação sobre Medicamentos - CIM: avaliação da informação prestada

Providing information about medication, an essential function of pharmaceutical practice to ensure rational drug use, is an important activity of hospital pharmacy services. The Drug Information Center of Onofre Lopes University Hospital (DIC-HUOL) initiated its activities in 1979 with the first Clinical Pharmacy Service in Brazil. The aim of this study was to assess information provided by DIC-HUOL, describing the profile of passive information offered by the center. A retrospective cross-sectional study was conducted to identify the profile of information requests (IR). One hundred percent of the IR received by the DIC between January 2008 and December 2009 were used. The results were divided by year to determine the influence of the restructuring process that occurred in 2008 and 2009. The study at DIC-HUOL showed a mean of 5.5 IR/month in 2008 and 20.3 IR/month in 2009; the mean of the last year is comparable to that of other Brazilian DIC. Most of the IR were made by medical residents (22.7%) in 2008 and by pharmacists (32.5%) in 2009. The significant use of the DIC by medical residents may be due to its location in a university hospital. The most recurrent types of IR concerned issues related to pathway/mode of administration (16.8%) and drug stability (13.1%) in 2008 and 2009, respectively. Requests were made verbally in 100% of the cases in 2008 and 78.8% in 2009, owing to the fact that most of the DIC users were professionals from the hospital itself. Time elapsed between request and response was not reported in 83.3% and 21.3% of the cases in 2008 and 2009, respectively. The most widely used bibliographic source during the two years was MICROMEDEX®, with 41.9% and 39.2%, respectively. The restructuring process had a positive influence on the DIC-HUOL, exhibiting similar parameters to those of other Brazilian DIC, but some of these parameters must be improved to achieve international standards

Legislação de rotulagem nutricional: instrumento de informação na promoção de escolhas alimentares - Natal-RN

Resolutions of the Board of numbers 359 and 360, of December 23, 2003, relating to Nutrition Labelling for Packaged Foods, establish quality standards and provide the education activities for health consumption, since one of the factors that enable the selection of healthier foods are the food labels as an important part in nutrition education. This is a descriptive study with a cross-sectional design. To calculate sample size, it was considered a margin of error of 20%, confidence level of 95% and prevalence of 52.5% for verifying nutritional information in a pilot study conducted in 2007. A total of 145 subjects were interviewed, resulting in 371 consumers in Natal, Rio Grande do Norte, Brazil, in order to determine prevalence of consulting nutritional information contained on food labels as a nutritional guideline for consumers and its association with sociodemographic variables as well as identify the intervention measures suggested by intervieweds so that this information can be better used to select healthy foods. Twenty-five of the 69 supermarkets belonging to the Supermarket Association of Rio Grande do Norte (ASSURN) were randomly selected. Data collection relied on interviews and extensive direct observation, using a semi-structured form composed of eight closed questions, some of which were multiple choice, and ten open questions. The chi-square test was performed for statistical analysis, using Statistical Package for Social Sciences (SPSS) 15.0 software. Label information most consulted was: expiry date (91.6%); product brand (49.4%); nutritional information (47.0%); zero trans fat (32.9%); zero sugar content (12.8%); zero fat content (3.0%); rich in fibers (2.7%); whether light or diet (30.4%); list of ingredients (16.8%); whether the product contained gluten or not (4.1%). When asked about the importance of nutritional information, 96.8% of the subjects responded important or very important ; of these 46.6% and 3.8% reported partially or totally understanding the information presented. It was found that 41.6% of the consumers consulted nutritional information for dietary reasons related to nontransmissible chronic diseases and 35.7% to be able to choose healthier foods. The data show a significant association between motivation to choose healthier foods and higher family income and schooling (p<0.0001). The intervention measures mentioned to make nutritional information better understood and used were: information and orientation about nutritional information, provided by qualified professionals in the supermarkets, the commercial establishment or the product manufacturer (73.9%) and media disclosure about the nature, importance and purpose of nutritional information (42.9%). In despite of communication noises the consumers use the nutrition claim for the nutritional guidance, showing association with some demographic variables. However, they desire the implementation of intervention measures that can be contextualized in the political construction of nutrition education to promote healthy food choices

Informação fluida e conhecimento no ciberespaço : uma análise do Portal Infonet-SE

The internet is a transbordering and potentializing environment for the information, since it makes possible the sheering, distribution and interaction of the contents available in it. However, this information system may generate an opposing move when it produces an avalanche of superficial information which difficult the absorption criticism by the user. This modern-liquid society, which is characterized by short living fashionisms, creates a fluid subject on which its habits do not become concrete, since they are so temporary that they don t shape up. The information also reproduces the same scenario, since the user is inserted into a logic based on supplying information and so it is conditioned to consume, not absorb or transform them into knowledge, since the flow of content production does not allow it. It is in his context that the publishing of cultural expressions come to be questioned, since they follow a liquid society trend. This discussion will take on topics that approach diverse cultural expressions in Sergipe, such as cinema, theater, craftsmanship, events, memory spaces(museums, art galleries, memorials, files, libraries, history institutes, science academies), amongst others and will analyze the content production of the Infonet Portal, from the reports published during April, May and June of 2008, period considered to be of cultural turbulence in the state, due to the June Festivals (Saint john, Saint Joseph and Saint Peter). To do so, Zigmunt Bauman s, Pierre Levy s, Edgar Morin s and Dominique Wolton s ideas were discussed. Besides, were analyzed the characteristics of the internet and its applicability within the portal hereby discussed in order to perceive the way the information is produced in the cyber culture, a movement that allows memorization, potentialization, interaction , besides other criteria inherent to the cyberspace

Registro da informação sobre nascidos vivos no nordeste: uma avaliação da evolução do SINASC entre 2000 e 2010

Os nascimentos ocorridos em uma população consistem em informação de grande valia para diversos estudos e planejamento de políticas públicas. O Sistema de informações sobre Nascidos Vivos (SINASC) representa uma promissora fonte de informação sobre o tema, uma vez que coleta continuamente e no âmbito municipal, dados sobre nascimentos. Tendo em vista a necessidade de avaliação contínua do SINASC e o panorama do declínio da fecundidade no Nordeste, objetivou-se avaliar a qualidade das informações provenientes do SINASC para o Nordeste, estados e microrregiões, nos anos 2000 e 2010, utilizando o Censo Demográfico como informação de referência, avaliando a cobertura do SINASC e identificando níveis e padrões de fecundidade. Pretendeu-se ainda verificar a relação entre os níveis de fecundidade, o grau de cobertura do SINASC e as condições socioeconômicas das microrregiões sintetizadas pelo Índice Social de Desenvolvimento Municipal (ISDM), utilizando-se a análise de cluster, associada à análise de variância (ANOVA) e o teste de Tukey. Por último, analisou-se a incompletude no preenchimento dos campos da Declaração de Nascido Vivo (DNV). De acordo com os resultados, observou-se que houve ampliação da qualidade das informações do SINASC no período estudado, resultando em uma maior aproximação das TFTs oriundas das duas fontes de dados consideradas no estudo. Maranhão e Paraíba foram os estados com maiores ganhos em cobertura das TFTs no período, e os estados do Rio Grande do Norte e Sergipe revelaram um grau de cobertura ligeiramente inferior em 2010 frente aos resultados de 2000, bem como ainda persistem várias microrregiões com TFTs oriundas do SINASC bem abaixo daquelas estimadas pelo Censo. Na verificação da associação entre o ISDM, TFTs e cobertura, a análise de cluster resultou em três agrupamentos, GrISDM A com melhores coberturas, ISDM e mais baixas TFT; GrISDM B , intermediário e GrISDM C com piores coberturas, ISDM e TFT mais altas. Notou-se a evolução das condições socioeconômicas no Nordeste, tendo o GrISDM A passado de 8% do total de microrregiões em 2000 para 37% em 2010. Reiterou-se ainda que quanto melhores as condições socioeconômicas de uma população, menores são as TFTs e melhores as coberturas do SINASC. A análise de variância apontou interações significativas entre o ano estudado versus ISDM (p-valor < 0,016) e o ano versus fonte de informação (p-valor < 0,020), e o teste Tukey apontou que não houve similaridade entre as médias das TFT das fontes Censo versus SINASC no período, fato que aponta para a captação ainda deficiente do SINASC nas microrregiões. O resultado da análise de variância da cobertura do SINASC em relação ao Censo apresentou uma interação significativa entre as variáveis UF versus Ano (p-valor < 0,0001), causada pelos estados que apresentaram queda de cobertura entre 2000 e 2010. Quanto à incompletude dos itens da DNV, evidenciou-se uma melhor coleta no período, embora alguns itens ainda careçam de atenção, como o apgar no 1º e 5º minuto e ocupação da mãe, sendo esta a que apresenta maiores percentuais de informações ignoradas. Destaca-se a possibilidade de preenchimento inconsistente nas variáveis referentes ao histórico de gestações anteriores, com o uso da informação zero inserida no lugar da informação ignorado . Concluiu-se que o SINASC é uma importante base de dados sobre nascimentos e que dispõe de dados confiáveis para o acompanhamento dos nascimentos e de seu panorama epidemiológico no Nordeste brasileiro, embora para alguns estados, assim como para algumas microrregiões, ainda faz-se necessária a ampliação da cobertura do Sistema. As informações constantes na DNV podem servir como embasamento para diversos estudos sobre as condições epidemiológicas dos nascituros e das suas mães, e dos indicadores baseados as informações dos nascimentos

O direito à informação jornalística: garantias constitucionais ao direito de ser informado no sistema brasileiro.

The freedom of social communication referred to those freedoms exercised under of the media. The journalism is professional activity responsible for factual information, real, pluralistic and of the public interest, directed diffusely to social orientation. The right of the information, characterized as diffuse right or of fruition by uncertain and numerous holders, is subdivided in the right of the inform, inform yourself and right to be informed. The journalists, as occupants of a enlarged spectrum concerning of right of the inform, have responsibility for the information they disseminate, devoir that puts on the basis of the constitutional right to be informed. This duty is divided with journalistic companies, when them realized. In the research, examined the existence of constitutional guarantees the right to be informed. To answer the question, realized research to support bibliographical and documentary. The guaranty is a empirical preoccupation coated with legality, since lends itself effect concretize a right. Traced so a panel of guarantees of institutional imprint, substantive and procedural. Treating of the institutional guarantees the right to information, it would refer to true institutions (as the free press) and may begin subjective rights. In the case of substantial guarantees, we would have access to information, the confidentiality of the fonts and the incensurable feature of journalistic information. A guarantee peculiar would be constitution of bodies responsible for monitoring the quality of the vehicles of communication. Trace it also a panel strict of procedural safeguards, such as public civil action, the security s warrant, and the rights of petition and answer.

Da informação ao conhecimento :o jornalismo científico na contemporaneidade

The purpose of this dissertation is to analyze the actual nature of the Scientific Journalism, studying the historical facts from these informations segment, their matters production and the news industries that work with these specific niche of the contemporary journalism. It is taken into account the educational potential of the specialized journalism and it is considered the communication as a transdiciplinary science. To get into this point it was elected as an analyze category the Reception it Mediation Studies specially the north-americans theories besides the utilization also of the reportage concept to identify how to establish the epistemological relations between Communication and Education. Among the objectives of this dissertation are the investigation of the scientific character of the journalism; the analysis of the theoretical currents of Pedagogy that are based on the theory of Social Communication, as for example the Total Language and the analysis of the industrial and technological characteristics of the most important scientific and cultural magazines of Brazil, Northeast and Natal
