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

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.

The structure of Industrial Automation bases on a hierarchical pyramid, where restricted information islands are created. Those information islands are characterized by systems where hardware and software used are proprietors. In other words, they are supplied for just a manufacturer, doing with that customer is entailed to that supplier. That solution causes great damages to companies. Once the connection and integration with other equipments, that are not of own supplier, it is very complicated. Several times it is impossible of being accomplished, because of high cost of solution or for technical incompatibility. This work consists to specify and to implement the visualization module via Web of GERINF. GERINF is a FINEP/CTPetro project that has the objective of developing a software for information management in industrial processes. GERINF is divided in three modules: visualization via Web, compress and storage and communication module. Are presented results of the utilization of a proposed system to information management of a Natural Gas collected Unit of Guamar´e on the PETROBRAS UN-RNCE.

O objetivo deste estudo foi estimar a entropia conjunta do sistema visual humano no domínio do espaço e no domínio das freqüências espaciais através de funções psicométricas. Estas foram obtidas com testes de discriminação de estímulos com luminância ou cromaticidade moduladas por funções de Gábor. A essência do método consistiu em avaliar a entropia no domínio do espaço, testando-se a capacidade do sujeito em discriminar estímulos que diferiam apenas em extensão espacial, e avaliar a entropia no domínio das freqüências espaciais, testando-se a capacidade do sujeito em discriminar estímulos que diferiam apenas em freqüência espacial. A entropia conjunta foi calculada, então, a partir desses dois valores individuais de entropia. Três condições visuais foram estudadas: acromática, cromática sem correção fina para eqüiluminância e cromática com correção para eqüiluminância através de fotometria com flicker heterocromático. Quatro sujeitos foram testados nas três condições, dois sujeitos adicionais foram testados na condição cromática sem eqüiluminância fina e um sétimo sujeito também fez o teste acromático. Todos os sujeitos foram examinados por oftalmologista e considerados normais do ponto de vista oftálmico, não apresentando relato, sintomas ou sinais de disfunções visuais ou de moléstias potencialmente capazes de afetar o sistema visual. Eles tinham acuidade visual normal ou corrigida de no mínimo 20/30. O trabalho foi aprovado pela Comissão de Ética em Pesquisa do Núcleo de Medicina Tropical da UFPA e obedeceu às recomendações da Declaração de Helsinki. As funções de Gábor usadas para modulação de luminância ou cromaticidade compreenderam redes senoidais unidimensionais horizontais, moduladas na direção vertical, dentro de envelopes gaussianos bidimensionais cuja extensão espacial era medida pelo desvio padrão da gaussiana. Os estímulos foram gerados usando-se uma rotina escrita em Pascal num ambiente Delphi 7 Enterprise. Foi utilizado um microcomputador Dell Precision 390 Workstation e um gerador de estímulos CRS VSG ViSaGe para exibir os estímulos num CRT de 20”, 800 x 600 pixels, 120 Hz, padrão RGB, Mitsubishi Diamond Pro 2070SB. Nos experimentos acromáticos, os estímulos foram gerados pela modulação de luminância de uma cor branca correspondente à cromaticidade CIE1931 (x = 0,270; y = 0,280) ou CIE1976 (u’ = 0,186; v’= 0,433) e tinha luminância média de 44,5 cd/m2. Nos experimentos cromáticos, a luminância média foi mantida em 15 cd/m2 e foram usadas duas series de estímulos verde-vermelhos. Os estímulos de uma série foram formados por duas cromaticidades definidas no eixo M-L do Espaço de Cores DKL (CIE1976: verde, u’=0,131, v’=0,380; vermelho, u’=0,216, v’=0,371). Os estímulos da outra série foram formados por duas cromaticidades definidas ao longo de um eixo horizontal verde-vermelho definido no Espaço de Cores CIE1976 (verde, u’=0,150, v’=0,480; vermelho, u’=0,255, v’=0,480). Os estímulos de referência eram compostos por redes de três freqüências espaciais diferentes (0,4, 2 e 10 ciclos por grau) e envelope gaussiano com desvio padrão de 1 grau. Os estímulos de testes eram compostos por uma entre 19 freqüências espaciais diferentes em torno da freqüência espacial de referência e um entre 21 envelopes gaussianos diferentes com desvio padrão em torno de 1 grau. Na condição acromática, foram estudados quatro níveis de contraste de Michelson: 2%, 5%, 10% e 100%. Nas duas condições cromáticas foi usado o nível mais alto de contraste agregado de cones permitidos pelo gamut do monitor, 17%. O experimento consistiu numa escolha forçada de dois intervalos, cujo procedimento de testagem compreendeu a seguinte seqüência: i) apresentação de um estímulo de referência por 1 s; ii) substituição do estímulo de referência por um fundo eqüiluminante de mesma cromaticidade por 1 s; iii) apresentação do estímulo de teste também por 1 s, diferindo em relação ao estímulo de referência seja em freqüência espacial, seja em extensão espacial, com um estímulo sonoro sinalizando ao sujeito que era necessário responder se o estímulo de teste era igual ou diferente do estímulo de referência; iv) substituição do estímulo de teste pelo fundo. A extensão espacial ou a freqüência espacial do estímulo de teste foi mudada aleatoriamente de tentativa para tentativa usando o método dos estímulos constantes. Numa série de 300 tentativas, a freqüencia espacial foi variada, noutra série também de 300 tentativas, a extensão espacial foi variada, sendo que cada estímulo de teste em cada série foi apresentado pelo menos 10 vezes. A resposta do indivíduo em cada tentativa era guardada como correta ou errada para posterior construção das curvas psicométricas. Os pontos experimentais das funções psicométricas para espaço e freqüência espacial em cada nível de contraste, correspondentes aos percentuais de acertos, foram ajustados com funções gaussianas usando-se o método dos mínimos quadrados. Para cada nível de contraste, as entropias para espaço e freqüência espacial foram estimadas pelos desvios padrões dessas funções gaussianas e a entropia conjunta foi obtida multiplicando-se a raiz quadrada da entropia para espaço pela entropia para freqüência espacial. Os valores de entropia conjunta foram comparados com o mínimo teórico para sistemas lineares, 1/4π ou 0,0796. Para freqüências espaciais baixas e intermediárias, a entropia conjunta atingiu níveis abaixo do mínimo teórico em contrastes altos, sugerindo interações não lineares entre dois ou mais mecanismos visuais. Este fenômeno occorreu em todas as condições (acromática, cromática e cromática eqüiluminante) e foi mais acentuado para a frequência espacial de 0,4 ciclos / grau. Uma possível explicação para este fenômeno é a interação não linear entre as vias visuais retino-genículo-estriadas, tais como as vias K, M e P, na área visual primária ou em níveis mais altos de processamento neural.

Considering the investigating course of Information Science which, under different perspectives, admits theoretical constructions influenced by objective and/or subjective and/or social dimensions of information, this paper aims to identify conceptual elements about notions of user employed in modeling constructs in the area. For such, an investigation was made in a corpus comprised of 15 literature reviews on need, search, behavior and use of information published in the Annual Review of Information Science and Technology - ARIST. Corpus analysis allowed to illustrate the subject-object relation in traditional and alternative approaches, directed towards objective and subjective dimensions of information. It also allowed to propose systemic and emerging models, the latter comprising of the relative attraction of subjective and social dimensions. In the end, a table is outlined with results pointing towards the displacement and/or transcendence of the strict notion of subject, underlying as a singularity managing or using information in a system - then considering, complementarily, other possibilities for acting. In this direction, the subject is then conceived not only in terms of management or use actions, but also taking as fundament his/her agency in the process of appropriation and construction of information and knowledge, interactively and in context.

The information professional as essential component in the soccer‟s club and this article approaches the importance of the information professional insertion inside the soccer‟s club. Know the structure of the clubs, as well like identify the diverse information that are inserted in this context – internal and external environment – of these organizations is necessary for a better comprehension of the activities that the information professional can perform in the clubs. Carrying out a parallel with the organizational structure model proposal by Mintzberg (1995) with the structure of Marília Athletic Club stayed clear the need of the information professional insert, therefore the Club is inserted in a highly competitive environment, there is many information, but little explored.

O estudo empírico objeto deste trabalho de investigação tem como pretensões avaliar, por um lado, o nível de divulgação sobre o risco de liquidez praticado por catorze instituições bancárias a operar no sistema financeiro português, e, por outro lado, aferir dos fartor4es determinante dessa mesma divulgação. Deste modo, foi utilizada a técnica de analise de conteúdo sobre os Relatórios e Contas de catorze instituições bancárias, relativamente ao período compreendido entre 2007 e 2011. Para tal, construiu-se um índice de divulgação com base nas recomendações do Comité de Suspensão Bancária de Basileia e definiu-se um conjunto de variáveis potencialmente explicativas do nível de divulgação. Os resultados demonstraram que as variáveis dimensão e exercício económico foram as variáveis que se apresentaram como estatiscamente significativas na explicação do grau da divulgação. No entanto, o estudo evidenciou algumas limitações, tais como o tamanho da amostra e o período de analise, que a ser contornadas poderiam melhorar os níveis de divulgação obtidos.

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.
