Ciência da informação: atuação profissional e as contribuições para o desenvolvimento do campo científico por parte dos egressos do PPGCI (ICI/UFBA)

Diante do conflito do mundo do trabalho provocado pelas mudanças tecnológicas em que fronteiras profissionais desaparecem, acredita-se ser de fundamental importância pesquisas subsidiem o desenvolvimento de novas trajetórias da formação e as demandas de contexto. Relata-se uma investigação sobre a atuação profissional e a contribuição de egressos da Pós-Graduação do Instituto de Ciência da Informação (UFBA-POSICI) para o campo científico da área, que defenderam suas dissertações no período de 1998-2006, apresentando indicadores que permitiram analisar tendências sobre o desempenho dos cursos, dos próprios titulados e do seu mercado profissional. Percebeu-se, por meio dos dados coletados e analisados, que diferentes questões puderam ser visualizadas no tocante à atuação profissional, à contribuição do campo científico da CI e quanto à importância dos cursos de pós-graduação para os processos de inovação do conhecimento da sociedade.

Relações mútuas entre informação e conhecimento: o mesmo conceito?

A proximidade entre os conceitos de informação e conhecimento provoca desordem conceitual em estudos na ciência da informação. Em contrapartida, o estabelecimento científico de uma disciplina depende de clareza conceitual acerca de seu objeto de estudo. Em vista disso, a hipótese proposta demonstra a necessidade de se mapearem as relações conceituais existentes entre informação (objeto de estudo da área) e conhecimento, objetivando evidenciar a distinção destes, para que possam ser usados com menos ambiguidade pelos pesquisadores da área. Para tanto, discutem-se, primeiramente, os conceitos de ciência da informação e de seu objeto de estudo, sob três paradigmas propostos por Capurro: fisicista, cognoscente e social; em seguida, algumas relações conceituais entre informação e conhecimento e suas consequências - existem relações de semelhança entre ambos, mas isso não faz com que se tornem idênticos. Definições anteriores sobre tais termos podem já ter constatado essas relações, contudo raramente esse assunto foi tratado de maneira pontual e com atenção, na falsa justificativa de que é um debate puramente teórico e que não levaria a resultado útil algum.

Sentidos do trabalho informacional corporativo: uma investigação sobre o impacto do conhecimento no trabalho contemporâneo

This study proposes and uses a multipolar qualitative methodology for the investigation of the meanings of corporate work under the impact of the technical-scientific knowledge. Based on the constructionist epistemology and on a heideggerian approach, this methodology made possible the description of such phenomenon under the Management perspective, but also under the Psychology, Sociology and Philosophy views. Study starts with empirical data, collected by interviews and in publications, and analyzes them based on conceptual contributions from the four referred poles. As a result, this investigation proposes reflexivity, impermanence and entanglement as meanings of the corporate work that culminate in the paradoxical work. It also demonstrates that the impact of knowledge occurs in a reflexive spiral of complexification, continuously affecting individuals and work processes; describes the impermanent character of the work ruled by time, by neophilia and by uncertainties that make precarious the very subjective experience of worker; and proposes that this work becomes entangled due to the way it is managed, and is an entangling work, for embarrassing the individual in its techniques, logics and dissonances. The paradoxical essence that emerges from this appreciation of corporate work is described on the following scopes: its reflexivity does not prevent its rationality to be fragile; its dynamism coexists with the difficulty to achieve substantive organizational changes; its entanglement compromises the possibilities of an apparently reachable well-being; its focus on present ends up to be emptied; and its purpose of individual sustenance becomes unsustainable due to hyperconsumption. But the conclusions of the study do no describe a definitive phenomenon. At the ending, it points out possibilities of living with the paradoxical work as well as possibilities of its transformation.

O que e o método científico: uma reflexão crítica sobre o método científico como subsídio para o ensino das ciências naturais

Ensinar ciência e, acima de tudo, ensinar o método científico e desenvolver a atitude crítica do estudante. Isto significa substituir a visão da ciência como uma coleção de fatos e teorias definitivamente estabelecidos, pela visão da ciência como um conhecimento racional - Porque crítico -, conjectural, provisório, sempre capaz de ser questionado e corrigido. Significa também opor à visão da ciência como uma representação completa e perfeita de fenômenos diretamente observáveis, a visão da ciência como uma reconstrução idealizada e parcial da realidade, que explica o visível pelo invisível. Nessa linha de raciocínio, devemos opor à idéia de uma observação pura e imparcial dos fatos, a ideia da observação guiada por hipóteses e teorias. Ensinar o meto do cientifico é questionar a ideia de que descobrimos e verificamos hipóteses através de procedimentos indutivos, substituindo-a pela ideia de que inventamos conjecturas ousadas, surgidas de nossa imaginação. Essas conjecturas, contudo, deverão ser testadas o mais severamente possível, através de tentativas de refutação que façam uso de experimentos controlados. No lugar da ilusória busca de teorias verificáveis, verdadeiras -ou pelo menos cada vez mais prováveis devemos buscar teorias de maior refutabilidade, cada vez mais amplas, precisas, profundas, de maior grau de corroboração e, talvez, mais próximas da verdade. Finalmente, ensinar o método científico significa também criticar cada uma das visões alternativas de ciência, propondo novos critérios para avaliar hipóteses e teorias científicas. É desnecessário dizer que estes critérios, por sua vez, devem também ser criticados, visto que a ausência de discussão crítica e a aceitação passiva e dogmática de um conjunto de ideias ou teorias e a não ciência, a pseudociência, enfim, a negação do espírito crítico e da racionalidade do homem.

O impacto do conhecimento concreto na aprendizagem escolar: a inovação das práticas pedagógicas é o caminho possível?

Este estudo pleiteia a discussão acerca do conhecimento concreto da criança que aprende com mais autonômia, como ferramenta indispensável para construir práticas pedagógicas inovadoras, tendo o docente como seu mediador. No intuito de compreender a inovação pedagógica o locus pesquisado foi o Grupo Escolar Luís Viana Filho localizada no município de Ibirapitanga - Bahia - Brasil, na tentativa de compreender os saberes e as práxis utilizadas como valorização do saber científico. Trata-se de uma pesquisa etnográfica, na qual se compreende a criança e o docente como sujeitos protagonistas do processo de construção efetiva de saberes, percebendo a importância da escola como um dos ambientes propiciadores da construção de aprendizagens. Os resultados permitiram refletir acerca da postura tanto dos alunos quanto do professor no desenvolvimento do cotidiano da sala de aula, valorizando os diversos ambientes sociais como espaços de aprendizagens e priorizando a atuação da criança como desveladora de seus próprios saberes.

O menino é o pai do homem: raízes crianceiras do conhecimento

This dissertation is a work on playing and its relation with the knowledge production process. It is the result of a set of personal experiences with the cultural universe of children which have instigated a look into the way they explore the world and questions about the very nature of the games they play. Could we consider those games hide, or rather reveal important strategies used in the knowledge production process and in making science. In light of several studies concerning the complexity of science, this questioning has also led to the development of a toy (a box), which consists of a range of pieces (photos, video, audio, stones, seeds, rags, envelopes, etc.). My intention is to show in a practical manner a strategy of thinking similar to the sensitive logic bricolage present in the playing, in order to instigate the reflection on the possibility of its inclusion in the production of the knowledge and science making processes

Body art, existência e conhecimento :a percepção do corpo na Educação Física

In the Renaissance, the anatomy project a map of the body. Since then, the human body has been investigated for innumerable techniques, configuring new landscapes on the condition human being and the proper knowledge. In accordance with Merleau-Ponty (1975), All technique is body technique. It configures and extends the Metaphysical structure of our meat. In this direction, any intervention in the human body, a tattooing, a surgery or a performance, extends the perception and the directions of the existence of the subject. Merleau-Ponty (1975) still affirms, that all technique presents objective interventions. However, the body, ahead of these interventions, doesn t have to be considered only object, but subject that, from the interventions, attributes sensible and meanings through the movements, also being this its way of being in the world. Searching to extend this reflection on the discontinuities between the object body and the subject body, as well as, with the objective to reflect on the relation between the corporal techniques and the production of the subjectivity and the knowledge of the physical education, we reflect on the body art, as one technique of body that marks the exterior of the body, exteriorizing the subjectivity, to search new means to the body and that ahead of this, we believe being able to project innumerable directions for the corporal transformations in the contemporarily. As a method for our reflection in we will support them in the phenomenology. IT presents as a new ontology, in which distinction does not occur enters the operating paper of the citizen that knows and the influence of the known object. The phenomenological understanding of body will be able to contribute with the knowledge of the Physical Education, a time that gives us important arguments on the experience of the body in relation with the nature, the culture, history. To be a body is to be tied to a world that we do not possess completive, but that we do not cease to search it

Validação de instrumentos para avaliação da habilidade e do conhecimento acerca da medida da pressão arterial

This study aimed to validate tools for evaluating the ability and knowledge about blood pressure (BP) among nursing students. It is a cross-sectional, descriptive, quantitative and methodological study accomplished at the Universidade Federal do Rio Grande do Norte (UFRN), Universidade do Estado do Rio Grande do Norte (UERN) and a private university of the state. The sample consisted of 27 judges of research selected from the inclusion criteria: nursing, teachers of the semiology and/or semiotics discipline, with at least 1 year of experience, being from UFRN, EEN, UERN and private university of the state and and agree to participate voluntarily with the signing of the consent form. The research was development in three stages: construction of two instruments based on the scientific literature, resulting in a structured checklist consists of 28 items and a knowledge questionnaire with 12 questions; submission of the instruments to the judges, in the period from June to September 2012, which should evaluate each item in appropriate , appropriate with changes and inappropriate , addition to making an overall assessment of each instrument based on 10 requirements; validation and verification to the level of agreement among the judges, through the application of Kappa and Content Validity Index (CVI). Was used the consensus level greater than 0.61 (good) to the Kappa index and greater than 0.75 for CVI. Was approved by the Ethics in Research / HUOL. After being coded and tabulated, the data were analyzed using descriptive statistics. Of the 27 judges who evaluated the instrument, 77.8% are female, with a mean age of 36.6 (± 9.0) years, 63.0% worked in UFRN, 74.1% had academic master and 63.0% worked exclusively on teaching. Average length of teaching experience was 7.9 (± 8.0) years and in the semiology and/or semiotics discipline of 5.5 (± 6.7) years. In the judgment of structured checklist and questionnaire of knowledge about blood pressure mensurement any item/question was considered inappropriate since all obtained level of agreement within the indices established (CVI> 0,75 E Kappa> 0.61). In relation to structured checklist, of those 28 items present, 9 showed perfect concordance index (CVI = 1.00, Kappa = 1.00) and another 19 were considered appropriate with changes, especially with regard to clarity and vocabulary. In the questionnaire of knowledge, among the 12 questions that comprised, 7 had perfect concordance index and the others were considered appropriate with changes as requirements as clarity, vocabulary, and feasible sequence of instructional topics. In terms of a overall evaluating of instruments, the structured checklist got CVI of 0.94 and Kappa of 0.89 and the knowledge questionnaire, CVI of 0.97 and a kappa of 0.94. Both instruments proved to be valid as to their content, configuring it as clear and objective tools of assessment of knowledge and ability on blood pressure, being of nursing students as well as others students and health professionals, since the use of valid measures seeking to reduce the risk of distorting the results

Um sistema para gestão do conhecimento em ameaças, vulnerabilidades e seus efeitos

Attacks to devices connected to networks are one of the main problems related to the confidentiality of sensitive data and the correct functioning of computer systems. In spite of the availability of tools and procedures that harden or prevent the occurrence of security incidents, network devices are successfully attacked using strategies applied in previous events. The lack of knowledge about scenarios in which these attacks occurred effectively contributes to the success of new attacks. The development of a tool that makes this kind of information available is, therefore, of great relevance. This work presents a support system to the management of corporate security for the storage, retrieval and help in constructing attack scenarios and related information. If an incident occurs in a corporation, an expert must access the system to store the specific attack scenario. This scenario, made available through controlled access, must be analyzed so that effective decisions or actions can be taken for similar cases. Besides the strategy used by the attacker, attack scenarios also exacerbate vulnerabilities in devices. The access to this kind of information contributes to an increased security level of a corporation's network devices and a decreased response time to occurring incidents

Extração e Representação de Conhecimento de Séries Temporais de Demanda de Energia Elétrica Usando TSKR

The opening of the Brazilian market of electricity and competitiveness between companies in the energy sector make the search for useful information and tools that will assist in decision making activities, increase by the concessionaires. An important source of knowledge for these utilities is the time series of energy demand. The identification of behavior patterns and description of events become important for the planning execution, seeking improvements in service quality and financial benefits. This dissertation presents a methodology based on mining and representation tools of time series, in order to extract knowledge that relate series of electricity demand in various substations connected of a electric utility. The method exploits the relationship of duration, coincidence and partial order of events in multi-dimensionals time series. To represent the knowledge is used the language proposed by Mörchen (2005) called Time Series Knowledge Representation (TSKR). We conducted a case study using time series of energy demand of 8 substations interconnected by a ring system, which feeds the metropolitan area of Goiânia-GO, provided by CELG (Companhia Energética de Goiás), responsible for the service of power distribution in the state of Goiás (Brazil). Using the proposed methodology were extracted three levels of knowledge that describe the behavior of the system studied, representing clearly the system dynamics, becoming a tool to assist planning activities

Educação científica no contexto pós-ontológico: por uma concepção plural de conhecimento e educação

The development of this work arises from the research of sociological and philosophical characters contemplating also other approaches which aims to answer the followingquestions: what is the responsibility of science teaching for the image one has about science? ; which scientific education should be designed for nowadays? . After considering the assumptions brought along by rationalism and the criticisms to the illuminist model proposed by sociology and philosophy of science, as well by the biology of the knowing process, going through discussions concerning post-modernity issues, one is given to understand that the image of science has become the central point of discussion in the last hundred years, including what concerns the area of science teaching, and that practically none of those discussions really reached natural science classes indeed. We adopt the term postontological to characterize the recent proposals on philosophy and sociology, because we evaluate that this term allows a better identification of the scientific realism crisis, which supports the existence of an ontological domain which science, and only science, is able to understand. One notices that the general public is not aware of those discussions, mainly if they are science teachers and students. So we believe that discussing the logic in which science is structured, the new understandings concerning the scientific undertaking, especially those of an externalist character, and the relationship between science and society, all of this contributes to build up a science teaching which contemplates a reflective contribution, besides allowing the inclusion of the study of other epistemologies in the educational practice. We argue that a revisionist posture seems to be the most appropriate for the contemporary scientific education, contemplating, besides the teaching of the usual science contents, discussions on the issues involving that knowledge, as well as respecting epistemologies alternative to the modern Western scientific one, in order one can work on the perception of local knowledge generated from other epistemological bases. We describe here practical activities we did involving teachers (short-term courses) and high-school students in an inland school in the Rio Grande do Norte state, in Brazil, as a way to demonstrate the possibility of interventions which can take those conceptions, discussions and changes to the classroom
