The current article aims to update the discussion on the South American context making use of the theory of Regional Security Regional Complexes (RSC). It begins with a theoretical discussion, based on Buzan and Wæver's work. It then presents the hypothesis that, differently from what is assumed in the literature, the South American RSC is not a standard one, but a centred one, in which the centre is not a global power. An empirical analysis follows, showing that Brazil possesses the necessary resources, and has presented some cogent political initiatives, such as the creation of the Union of South American Nations (Unasur) and its Defense Council (SDC), but in other moments has been reluctant take a leadership role in South America. The analysis concludes that, regarding its configuration, the South American RSC corroborates the authors' hypothesis and that Brazil should consolidate its role at the centre of such a complex.

Os sanitizantes químicos tradicionais utilizados na indústria de alimentos apresentam, como desvantagem, o possível desenvolvimento de resistência e adaptação bacteriana, interferindo na eficiência bactericida mínima destes produtos. Os óleos essenciais com atividade antimicrobiana despertam grande interesse na indústria de alimentos, pela possível utilização como princípios ativos de sanitizantes. Esta pesquisa objetivou determinar a concentração inibitória mínima (CIM) dos óleos essenciais (OEs) de cravo-da-índia e canela contra bactérias Gram positivas (Staphylococcus aureus e Listeriamono cytogenes) e Gram negativas (Escherichia coli e Salmonella sp.) e compará-la com a CIM do hipoclorito de sódio, além de determinar a concentração bactericida mínima (CBM) dos OEs para L. monocytogenes. Foi utilizado o método da microdiluição e os OEs foram caracterizados, quimicamente, por cromatografia gasosa - espectrometria de massa. Os componentes principais dos OEs de canela e cravo-da-índia foram o cinamaldeído (67,58%) e o eugenol (77,58%), respectivamente. A CIM do OE de canela foi de 0,04%, para as bactérias Gram positivas, e < 0,02%, para a bactérias Gram negativas. O OE de cravo-da-índia teve CIM de 0,04% para Salmonella sp., 0,06% para E. coli e S. aureus e 0,08% para L. monocytogenes. Para todas as bactérias testadas, a CIM do hipoclorito de sódio foi > 0,2%. A CBM para L. monocytogenes, no OE de cravo-da-índia, foi de 0,18% e o OE de canela destacou-se por apresentar CBM < 0,02%, demonstrando a possibilidade do uso destes OEs, principalmente o de canela, como princípios ativos de sanitizantes.

Introduction: Studies about human cognition represent a relevant perspective in information science, considering the subjective actions of information professionals and dialogic process that should permeate the activity of subjects dealing with the organization and representation of information. Objective: Explore the approach of the cognitive perspective in information science and their new settings by contemporary needs of information to reflect on the process of meeting the professional information through the social reality that permeates the contexts of information. Methodology: Reflection on theoretical aspects that deal with the cognitive development to discuss the implications of the cognitive approach in information science and its evolution in the scope of the representation and processing of information. Results: Research in Information Science must consider issues of cognitive and social order that underlie information processing and the process of knowing the information professional as knowledge structures must be explained from the social context of knowing subjects. Conclusions: There is a need to investigate the process of knowing the information professional in the bias of socio-cognitive approach, targeting new elements for the understanding of the relationship information (cognitive manifestations) and its implications on the social dimension.

This article aims to address the relationship between work and professional education, specifically the ideology skills and the new pedagogy business under the globalization of capital. Is analyzed at first, the world-historical context, the restructuring of the productive and political capital from the 1970s, and the demand for a new organization of work based on model Toyota. Second, discuss such changes are productive within the Brazilian state and its influence on educational policies geared to work, permeated by the ideology skills as an instrument that seeks to obscure the relationshipcapital. It discusses the emergence of new education business connected to the ideals of human capital. It is the influence of international organizations in Brazil of the United Nations (UN) and the United Nations Organization for Education, Science and Culture (UNESCO), aimed at articulating the education according to the ideological aspect global, verified legislative apparatus in education. Ends up not only to reflect the content of the skills ideology, but it is suggested the redemption value of the denied promise of emancipation human-general.
