Resumo O compartilhamento não consentido de artigos científicos gera controvérsias óbvias entre os atores que violam direitos autorais e as editoras comerciais, titulares desses direitos. No entanto, o acontecimento também gera implicações no próprio Movimento Open Access, que, tradicionalmente, defende que a retirada das barreiras aos artigos seja feita exclusivamente por vias legais. Nesta comunicação, exploram-se as controvérsias ligadas ao compartilhamento não consentido de obras científicas protegidas por direitos autorais. O objetivo deste texto é demonstrar a existência desse debate público, indicando as disputas por espaço e as narrativas correspondentes. Debate-se, assim, a possível crise gerada no Movimento Open Access em função de o recente avanço das iniciativas ilegais promover acesso a quase toda a literatura científica existente.

Abstract Unconsented sharing of scientific papers generates notable controversies between agents that violate copyrights and publishers, the copyright holders. However, this phenomenon also generates tensions even with the Open Access Movement, that traditionally advocates that the barriers to open access be overturned exclusively by legal mechanisms. In this paper, the controversies related to the unconsented sharing of scientific studies protected by copyrights are explored. The aim of this discussion is to demonstrate the existence of this public debate, showing the several quarrels for space and the related narratives. The crisis generated in the Open Access Movement by the recent development of illegal initiatives that managed to promote free access to almost all scientific literature is here considered.

Abstract: Our objective was to identify the understanding of theoretical aspects and the interpretation of practical situations that a sample of 3,623 graduate students (Population = 22,438) at the University of São Paulo (Brazil) have regarding academic plagiarism. The survey used an electronic questionnaire containing 30 multiple choice questions developed from the literature concerning the concept and definition of plagiarism, occurrence modality, types of plagiarism, reasons for occurrence, standards and preventive actions adopted. We identified that the fact of respondents agreeing or disagreeing with the theoretical-conceptual characteristics of plagiarism did not make a difference in their capacity of correctly assessing practical situations characterizing plagiarism. Moreover, the agreement or disagreement responses regarding the concepts of plagiarism were observed not to differ among the respondents who had been trained to use references and citations. However, the same respondents correctly interpret practical situations characterizing plagiarism. Therefore, this study suggests that there is a gap between theoretical and practical knowledge regarding plagiarism for graduate students. Although the technical training related to the correct use of research sources is an important prerequisite in the capacity-building process, it does not seem to be enough to prevent plagiarism practices.

PURPOSE: To investigate gender differences in the evolution of the inflammatory process in rats subjected to brain death (BD). METHODS: Adult Wistar rats were divided into three groups: female; ovariectomized female; and male rats. BD was induced using intracranial balloon inflation and confirmed by maximal pupil dilatation, apnea, absence of reflex, and drop of mean arterial pressure. Six hours after BD, histological evaluation was performed in lungs, heart, liver and kidneys, and levels of inflammatory proteins, estrogen, progesterone, and corticosterone were determined in plasma. RESULTS: In the lungs, females presented more leukocyte infiltration compared to males (p<0.01). Ovariectomized female rat lungs were more hemorrhagic compared to other groups (p<0.001). In the heart, females had higher leukocyte infiltration and tissue edema compared to males (p<0.05). In the liver and kidneys, there were no differences among groups. In female group estradiol and progesterone were sharply reduced 6 hours after BD (p<0.001) to values observed in ovariectomized females and males. Corticosterone levels were similar. CONCLUSIONS: Sex hormones influence the development of inflammation and the status of organs. The increased inflammation in lungs and heart of female rats might be associated with the acute reduction in female hormones triggered by BD.

OBJECTIVES: Experimental studies on sepsis have demonstrated that ethyl pyruvate is endowed with antioxidant and anti-inflammatory properties. This study aimed to investigate the effects of ethyl pyruvate on leukocyte-endothelial interactions in the mesenteric microcirculation in a live Escherichia coli-induced sepsis model in rats. METHODS: Male Wistar rats were administered an intravenous suspension of E. coli bacteria or were subjected to a sham procedure. Three hours after bacterial infusion, the rats were randomized into the following groups: a control group without treatment, a group treated with lactated Ringer’s solution (4 mL/kg, i.v.), and a group treated with lactated Ringer’s solution (4 mL/kg, i.v.) plus ethyl pyruvate (50 mg/kg). At 24 h after bacterial infusion, leukocyte-endothelial interactions were investigated using intravital microscopy, and the expression of P-selectin and intercellular adhesion molecule-1 was evaluated via immunohistochemistry. White blood cell and platelet counts were also determined at baseline and 3 h and 24 h after E. coli inoculation. RESULTS: The non-treated and lactated Ringer’s solution-treated groups exhibited increases in the numbers of rolling leukocytes (∼2.5-fold increase), adherent cells (∼3.0-fold), and migrated cells (∼3.5-fold) compared with the sham group. In contrast, treatment with Ringer’s ethyl pyruvate solution reduced the numbers of rolling, adherent and migrated leukocytes to the levels observed in the sham group. Additionally, the expression of P-selectin and intercellular adhesion molecule-1 was significantly increased on mesenteric microvessels in the non-treated group compared with the sham group (p<0.001). The expression of both adhesion molecules was reduced in the other groups, with ethyl pyruvate being more effective than lactated Ringer’s solution. Infusion of bacteria caused significant leukopenia (3 h), followed by leukocytosis with granulocytosis (24 h). There was also an intense and progressive reduction in the number of platelets. However, no differences were observed after treatment with the different solutions. CONCLUSIONS: The presented data suggest that ethyl pyruvate efficiently reduces the inflammatory response in the mesenteric microcirculation in an experimental model of sepsis induced by live E. coli and is associated, at least in part, with down-regulation of P-selectin and intercellular adhesion molecule-1.

OBJECTIVES: Brain death is typically followed by autonomic changes that lead to hemodynamic instability, which is likely associated with microcirculatory dysfunction and inflammation. We evaluated the role of the microcirculation in the hemodynamic and inflammatory events that occur after brain death and the effects of autonomic storm inhibition via thoracic epidural blockade on mesenteric microcirculatory changes and inflammatory responses. METHODS: Male Wistar rats were anesthetized and mechanically ventilated. Brain death was induced via intracranial balloon inflation. Bupivacaine (brain death-thoracic epidural blockade group) or saline (brain death group) infusion via an epidural catheter was initiated immediately before brain death induction. Sham-operated animals were used as controls (SH group). The mesenteric microcirculation was analyzed via intravital microscopy, and the expression of adhesion molecules was evaluated via immunohistochemistry 180 min after brain death induction. RESULTS: A significant difference in mean arterial pressure behavior was observed between the brain death-thoracic epidural blockade group and the other groups, indicating that the former group experienced autonomic storm inhibition. However, the proportion of perfused small vessels in the brain death-thoracic epidural blockade group was similar to or lower than that in the brain death and SH groups, respectively. The expression of intercellular adhesion molecule 1 was similar between the brain death-thoracic epidural blockade and brain death groups but was significantly lower in the SH group than in the other two groups. The number of migrating leukocytes in the perivascular tissue followed the same trend for all groups. CONCLUSIONS: Although thoracic epidural blockade effectively inhibited the autonomic storm, it did not affect mesenteric hypoperfusion or inflammation induced by brain death.

The objective of this study was to identify the perception of nurses working in teams implementing the Project Education through Work in the Family Health field, towards the activities developed in the Adolescent Health Program. This qualitative study was performed in Cuiabá (Mato Grosso state), with 17 nurses. Data collection was performed using a questionnaire with descriptive variables and open answers to be answered individually. The Collective Subject Discourse was used as the method to analyze the statements. The results permitted to generate seven central ideas: health care activities; adolescents' participation; intersectoriality; organization of the structure and care to adolescents; multidisciplinarity and interdisciplinarity; and the need for training about adolescence. In conclusion, not every Family Health team has offered activities of the Adolescent Health Program, therefore it is necessary to invest in permanent education of nurses that assist adolescents.

OBJETIVO: Avaliar o efeito da N-acetilcisteína (NAC) combinada ao fluido de reposição volêmica na morte celular pulmonar de ratos submetidos ao choque hemorrágico (CH) controlado. MÉTODOS: Duas artérias (cálculo da PAM e exsanguinação) e uma veia (tratamentos) foram cateterizadas em 22 ratos anestesiados. Dois grupos de ratos machos albinos foram induzidos ao CH controlado com PAM de 35mmHg por 60 min. Após este período, o grupo RL foi ressuscitado com Ringer lactato e o grupo RL+NAC foi ressuscitado com Ringer lactato associado com 150mg/Kg de NAC. O grupo controle sofreu somente o procedimento cirúrgico de cateterização. Os animais sofreram eutanásia após 120 min. da ressuscitação. Amostras de tecido pulmonar foram coletadas para histopatologia, TUNEL e a imuno-expressão da caspase 3. RESULTADOS: RL apresentou maior número de células marcadas pelo TUNEL do que RL+NAC, porém sem alteração na expressão da caspase 3 em nenhum dos grupos estudados. CONCLUSÃO: A N-acetilcisteína teve um papel protetor na morte celular em modelo de choque hemorrágico controlado.

PURPOSE: To evaluate the effect of N-acetylcysteine (NAC) combined with fluid resuscitation on pulmonary cell death in rats induced with controlled hemorrhagic shock (HS). METHODS: Two arteries (MAP calculation and exsanguination) and one vein (treatments) were catheterized in 22 anesthetized rats. Two groups of male albino rats were induced with controlled HS at 35mmHg MAP for 60 min. After this period, the RL group was resuscitated with Ringer's lactate and the RL+NAC group was resuscitated with Ringer's lactate combined with 150mg/Kg NAC. The control group animals were cannulated only. The animals were euthanized after 120 min of fluid resuscitation. Lung tissue samples were collected to evaluate the following: histopathology, TUNEL and imunohistochemical expression of caspase 3. RESULTS: RL showed a greater number of cells stained by TUNEL than RL + NAC, but there was no change in caspase 3 expression in any group. CONCLUSION: N-acetylcysteine associate to fluid resuscitation, after hemorrhagic shock, decreased cell death attenuating lung injury.

Este artigo consiste em pesquisa cujo objetivo foi conhecer o repertório cultural de professores de escolas públicas de Educação Básica de Uberaba e Uberlândia (MG). Fundamentada na teoria de Vigotski e na de Bourdieu, a pesquisa partiu do pressuposto de que a mediação para a aprendizagem será tanto melhor quanto mais abrangente e variado for o repertório de conhecimentos e experiências do mediador. Os professores responderam a questionários cujas respostas indicaram que a maioria não tem familiaridade com expressões da cultura erudita e com determinadas produções artísticas, principalmente devido aos baixos salários e às intensas jornadas de trabalho. Considerando-se que a escola, para muitos, é a única possibilidade de acesso à produção artística não massificada, a pesquisa aponta a necessidade de ampliar as investigações no sentido de aprofundar a discussão acerca da temática nela abordada, bem como a premência de se criar uma política pública para a formação cultural e estética de professores.

This article refers to the research that targeted the understanding of the cultural repertoire of public school teachers in primary and high school of Uberaba and Uberlândia cities (Minas Gerais state). Based on on Vygotsky’s and Bourdieu’s theories, the project assumes that the mediation for learning would be better as much as its repertoire of knowledge and experience is wide and varied. Data on the aesthetic experiences of teachers were collected through a questionnaire. The results indicate that the majority does not have the habit of visit spaces and cultural events, and that the familiarity with expressions of high culture is weak or virtually nonexistent, mainly due to low wages and intense days of work. Considering that the school is, for many, the only possibility of accessing the non mass artistic production, the study identifies the need to expand investigations that deepen the discussion about the topic it addressed, as well as the urgent need of creating a governmental policy to the cultural and aesthetic formation of teachers.

Este artículo se refiere a la investigación cuyo objetivo era conocer el repertorio cultural de los maestros de la enseñanza general básica de las ciudades de Uberaba y Uberlândia (MG). Basado en las teorías de Vigotski y la de Bourdieu. La investigación supone que la mediación para el aprendizaje será mucho mejor cuanto más amplio y variado sea su repertorio de conocimientos y experiencias. Los datos sobre las experiencias estéticas de los docentes fueron recolectados a través de un cuestionario. Los resultados indican que la mayoría de los docentes no tiene familiaridad con expresiones de la alta cultura, o que se debe, principalmente, a los bajos salarios y jornadas laborales intensas. Teniendo en cuenta que la escuela es, para muchos, la única posibilidad de acceso a la producción artística que no sea de masas, el estudio identifica la necesidad de ampliar las investigaciones para profundizar la discusión sobre el tema que aborda, como la urgencia de crear una política pública para el bienestar cultural y estético de los docentes.

O projeto de Arquitetura de Informação é uma das etapas iniciais do projeto de um website, por isso a detecção e correção de erros nessa etapa são mais fáceis e econômicas do que nas etapas seguintes. Porém, para minimizar erros, é necessária, para os projetos de Arquitetura de Informação, uma metodologia que organize o trabalho do profissional e garanta a qualidade do produto final. Foram analisados o perfil do profissional que trabalha com Arquitetura de Informação no Brasil (pesquisa quantitativa por meio de um questionário on-line) e as dificuldades, técnicas e metodologias encontradas nos seus projetos (pesquisa qualitativa por meio de entrevistas em profundidade com apoio da abordagem do Sense-Making). Conclui-se que as metodologias de projetos de Arquitetura de Informação precisam evoluir na adoção das abordagens de Design Centrado no Usuário e nas formas de avaliar seus resultados.

The project of Information Architecture is one of the initial stages of the project of a website, thus the detection and correction of errors in this stage are easier and time-saving than in the following stages. However, to minimize errors for the projects of information architecture, a methodology is necessary to organize the work of the professional and guarantee the final product quality. The profile of the professional who works with Information Architecture in Brazil has been analyzed (quantitative research by means of a questionnaire on-line) as well as the difficulties, techniques and methodologies found in his projects (qualitative research by means of interviews in depth with support of the approaches of the Sense-Making). One concludes that the methodologies of projects of information architecture need to develop the adoption of the approaches of Design Centered in the User and in the ways to evaluate its results.

This paper aims at discussing the theoretical-methodological fundaments of the historic-cultural psychology and its contributions to the development of the professional of education. The starting point is a research project carried out at a Municipal Centre for Chile Education in the town of Uberaba -MG. In the same way as we understand it and put in into practice, teacher training is a process which happens in the unity which is constituted by theory and practice, from which some conjectures occur. 1) direct teacher participation in his/her development process; 2) research approach wich puts the teacher as a collaborator; 3) the school as a locus of the teacher development an 4) collective activities as mediators of development. We highlight also that man's transformations in the school environment represent reorganization of the teaching system and of the discursive practices associated to him.

Este abordaje intenta discutir los fundamentos teórico-metodológicos de la sicología histérico-cultural y sus contribuciones en la formación del profesional de la educación, a partir de un proyecto de investigación desarrollado en un Centro Municipal de Educación Infantil de la ciudad de Uberaba/MG. Tal como entendemos y practicamos, la formación docente es un proceso que se da en la unidad constituida por la teoría y la práctica, del cual derivan algunas presuposiciones: 1) la participación directa del profesor en su proceso formativo; 2) el abordaje de la investigación que coloca al profesor como colaborador; 3) la escuela siendo el locus de la formación docente y 4) las actividades colectivas como mediadoras de la formación. Destacamos, también, que las transformaciones del hombre en el escenario de la escuela representan la reorganización del sistema de enseñanza y de las prácticas discursivas a ella asociadas.

OBJETIVOS: O objetivo do presente estudo é avaliar a fidedignidade de um instrumento destinado a mensurar a satisfação de doadores de sangue em um centro de hematologia e transfusão. SUJEITOS E MÉTODOS: Foi desenvolvido um questionário objetivando mensurar a satisfação dos doadores de sangue do Hemocentro/Ribeirão Preto, onde os mesmos classificaram 18 afirmativas em uma escala de Likert de 4 itens, variando de "totalmente errado" a "totalmente certo". Uma amostra de 407 doadores foi obtida sistematicamente, onde, a cada quatro pessoas que seqüencialmente compareceram para doação, o quarto era convidado a preencher o questionário. Uma amostra final de 407 doadores foi utilizada para a análise da fidedignidade do questionário e análises preliminares. A análise de correspondência (AC) foi utilizada para avaliação do grau de satisfação dos doadores para cada item. RESULTADOS: Os participantes tinham em média 31,2 anos (desvio padrão de 9,13 e amplitude de 18 a 67 anos). Foi encontrado um coeficiente alfa de Cronbach de 0,97, indicando uma consistência interna muito alta do questionário. A AC indicou que os itens com maior insatisfação são o acesso ao Hemocentro e o tempo gasto na doação. Itens de maior satisfação referem-se à confiança no serviço, funcionários e atendimento. A AC identificou que, de modo geral, as pessoas que estão doando sangue pela primeira vez tendem a uma menor satisfação. CONCLUSÃO: A alta consistência interna do questionário indica que os itens abordados têm alto poder de mensurar um mesmo objeto, mas ainda há a necessidade de estudar a validação do instrumento para avaliar se tal objeto é necessariamente a satisfação do doador.

OBJECTIVES: The purpose of this study was to evaluate the reliability of a self-reporting instrument to measure the Portuguese-speaking blood donor satisfaction in a hematology and blood transfusion center. SUBJECTS AND METHODS: Data were collected from 407 donors between February and May 2004 at Hemocentro - Ribeirão Preto, Brazil. The questionnaire included items concerning blood donor background characteristics. Eighteen items measuring donor satisfaction dealt with the quality of staff-donor relationship (range of responses from 1=negative to 4=positive). Item homogeneity was analyzed using Cronbach alpha coefficient. Data analysis was based on correspondence analysis. RESULTS: The mean age of responding donors was 31.2 years (standard deviation 9.13 years, range 18-67 years), about 65% were men and 35% were women. Cronbach alpha for the eighteen items measuring donor satisfaction was 0.97. Results showed that patient satisfaction was highest in items pertaining to staff-donor relationship, and trust in the services and care provided. Blood donors reported the most dissatisfaction with the access to Hemocentro and the time spent in donation. Results also showed differences in satisfaction rates between first-time blood donors and people who already had donated blood. CONCLUSION: The internal consistency of the questionnaire indicates that its items have a high capacity to measure the same object. However, its validity still requires further studies to confirm if this object is in fact blood donor satisfaction.

Esse trabalho discute os movimentos em encostas de Ouro Preto, a partir de um exemplo envolvendo um escorregamento em talude no Morro do Curral, localizado na Vila São José. Alerta-se acerca dos riscos de movimentos devido à inadequada ocupação urbana na base da encosta, enfatizando o problema da ação antrópica e suas conseqüências na reincidência de movimentos. A ação do intemperismo químico no comportamento do material rochoso é discutida. Um levantamento preciso do escorregamento em campo é apresentado, mostrando a geometria da superfície de ruptura. O levantamento de campo permitiu a exata reconstituição da superfície de ruptura.

In this work the landslides in Ouro Preto have been discussed through an example involving a landslide in a slope at Morro do Curral, situated in Vila São José. The risks of landslides due to the inadequate urban expansion at the base of the hill have been presented, pointing out the problem of the comeback of movements. The effect of chemical weathering on the rock mass behavior has been discussed. A precise field survey of the landslide has been presented, showing the geometry of the failure surface. The field survey allowed the exact reconstitution of the failure surface.
