A gestão estratégica do conhecimento sob os parâmetros dos modelos de governance corporativa nas empresas com capital aberto

This article covers the concepts about the knowledge management practices aligned with corporate governance in the organizations opened capital, highlighting the importance attached to these types of management assistance in the conduct of business organizations. Highlights the points that still have gaps existing in governance organizations models and proposes a discussion of what remains to be done by proposing the use of knowledge management models as a tool to aid the implementation of best governance practices. Through research conducted in a company with publicly traded and listed on Level 1 of corporate governance, it was possible to identify therelationship between knowledge management models aligned with corporate governance standards. A questionary that includes elements of corporate governancein line with the concepts and models of knowledge management was applied. After finding that there is strong alignment between knowledge management and corporate governance, we present the arguments about the contributions that this convergence can bring to the organization.

A dimensão interdisciplinar da análise documental nos contextos brasileiro e espanhol no âmbito da organização do conhecimento

Information organization can be considered as a nuclear area in Information Science and its historical background has been historically built based on three theoretical approaches: subject cataloguing, under a North-American influence, Indexing, under a British influence, and document analysis, under a French influence. In this sense, although one can consider the strong influence of the logic-linguistic approach of the French tradition in information organization both in Brazil and in Spain, it is not already clear in what extent the mentioned influence specifically occurs in Brazil and Spain as well as what are the dialogical perspectives between them. So, and in order to analyze how the Information Science academic environments in Brazil and in Spain conceive the interdisciplinary relationships in the domain of document analysis (DA), it was applied a questionnaire to Brazilian and Spain DO researchers based on the records of the Brazilian and the Spanish International Society for Knowledge Organization chapters. The results (64,5% of answers in Brazil and 60,6% in Spain) allowed the identification of 35 DA interdisciplinary relationships in Brazil and 98 in Spain, whose data were so grouped in 7 matrixes ? cognitive, philosophical, historical, logic-lingusitic, quantitative, social and political, and technological. It was possible to observe that the logical-linguistic matrix is strongly predominant (90% of the answers in Brazil and in Spain) what reflects the influence of the ideas of Jean-Claude Gardin. On the other side, the graphic visualization of authors´s network showed a strong perspective of dialogical relationships among Brazilian and Spanish DA researchers, based on the convergence of theoretical conceptions, what allow us to conclude the need of joint research policies between both coountries in order to make the mention ed dialogical relationships real and fruitful.

Creative Commons: a convergence model between the ideal of commons and the possibilities of creation in contemporary times, opposed to copyright impediments

The contemporary individual finds on the Internet and especially on the Web facilitating conditions to build a basic infrastructure based on the concept of commons. He also finds favorable conditions which allow him to collaborate and share resources for the creation, use, reuse, access and dissemination of information. However, he also faces obstacles such as Copyright (Law 9610/98 in Brazil). An alternative is Creative Commons which not only allows the elaboration, use and dissemination of information under legal conditions but also function as a facilitator for the development of informational commons. This paper deals with this scenario.

Dinâmica secular rotacional de corpos tri-axiais: expansão de V em ressonâncias de primeira ordem

Consider a finite body of mass m (C1) with moments of inertia A, B and C. This body orbits another one of mass much larger M (C2), which at first will be taken as a point, even if it is not completely spherical. The body C1, when orbit C2, performs a translational motion near a Keplerian. It will not be a Keplerian due to external disturbances. We will use two axes systems: fixed in the center of mass of C1 and other inertial. The C1 attitude, that is, the dynamic rotation of this body is know if we know how to situate mobile system according to inertial axes system. The strong influence exerted by C2 on C1, which is a flattened body, generates torques on C1, what affects its dynamics of rotation. We will obtain the mathematical formulation of this problem assuming C1 as a planet and C2 as the sun. Also applies to case of satellite and planet. In the case of Mercury-Sun system, the disturbing potential that governs rotation dynamics, for theoretical studies, necessarily have to be developed by powers of the eccentricity. As is known, such expansions are delicate because of the convergence issue. Thus, we intend to make a development until the third order (superior orders are not always achievable because of the volume of terms generated in cases of first-order resonances). By defining a modern set of canonical variables (Andoyer), we will assemble a disturbed Hamiltonian problem. The Andoyer's Variables allow to define averages, which enable us to discard short-term effects. Our results for the resonant angle variation of Mercury are in full agreement with those obtained by D'Hoedt & Lemaître (2004) and Rambaux & Bois (2004)

Limits on a strong electroweak sector from e(+)e(-)->gamma gamma+E at LEP2

We study the process e+e- γγνν̄ in the context of a strong electroweak symmetry breaking model, which can be a source of events with two photons and missing energy at LEP2. We investigate bounds on the model assuming that no deviation is observed from the standard model within a given experimental error.

BRAZILIAN OFFSHORE WAVE CLIMATE BASED ON NWW3 REANALYSIS

This paper provides a description of the wave climate off the Brazilian coast based on an eleven-year time series (Jan/1997-Dec/2007) obtained from the NWW3 operational model hindcast reanalysis. Information about wave climate in Brazilian waters is very scarce and mainly based on occasional short-term observations, the present analysis being the first covering such temporal and spatial scales. To define the wave climate, six sectors were defined and analyzed along the Brazilian shelf-break: South (W1), Southeast (W2), Central (W3), East (W4), Northeast (W5) and North (W6). W1, W2 and W3 wave regimes are determined by the South Atlantic High (SAH) and the passage of synoptic cold fronts; W4, W5 and W6 are controlled by the Intertropical Convergence Zone (ITCZ) and its meridional oscillation. The most energetic waves are from the S, generated by the strong winds associated to the passage of cold fronts, which mainly affect the southern region. Wave power presents a decrease in energy levels from south to north, with its annual variation showing that the winter months are the most energetic in W1 to W4, while in W5 and W6 the most energetic conditions occur during the austral summer. The information presented here provides boundary conditions for studies related to coastal processes, fundamental for a better understanding of the Brazilian coastal zone.
