Noções de sujeito em modelos teóricos na Ciência da Informação: do enfoque no sistema à consideração da agência em contexto

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.

PGCP - Plataforma para Gerenciamento Colaborativo de Projetos

Collaborative Systems are designed to support individuals in order to solve a problem together, or cooperatively (or collaboratively). Such systems have the advantage of not requiring the presence in the same location of the participants. The basis of any Collaborative System is communication, where users interact with each other in order to exchange information. Communication among individuals is accomplished through collaborative tools such as chat, email, document repository, etc.. Using these tools, companies can reduce operational costs, saving on travel and accommodation of its employees to attend meetings. The project members only need a computer with internet access to use collaborative tools. Project management is essential to the quality of the nal product. To perform a proper management, methodologies must be applied using methods, tools and procedures. There are some phases that are considered generic for all software process models, they are: de nition, development, maintenance and activity to support the software process. In this paper is described a platform for project management using the concepts and features of Collaborative Systems. The goal of this platform is to unify various collaborative tools (such as chat and document repository) in a project management system. Using the system, it becomes possible to manage projects, and the ability to maintain an active constant communication between members of each project

Comunicação interna: uma questão de qualidade

Internal Communications, a central theme of this project, it is essential to support a transparent and effective cooperation between organization and em ployee. In companies with Quality Management System, as certified in ISO 9001, need to adhere to the quality not only in its management policy, but as in all of its processes and the various agencies in which there is interaction, especially the internal. This paper aims to reflect on the interaction with the internal audience, paying attention to the fact that the information required and the strategic management of public relations positively interfere in the relationship between organization and employe e and the resulting benefits that these entail in quality management. The demonstration of the policies employed by the company Vien a Grafica & Editora as the basis for developing a model suggestive of internal communication in business quality. Thus, we intend to understand how effective communication arouses feelings of motivation and engagement among employees, so there is the realization of quality in all organizational sectors

Entropy effect in quantum computing and information: an open-source environment simulation

The technologies are rapidly developing, but some of them present in the computers, as for instance their processing capacity, are reaching their physical limits. It is up to quantum computation offer solutions to these limitations and issues that may arise. In the field of information security, encryption is of paramount importance, being then the development of quantum methods instead of the classics, given the computational power offered by quantum computing. In the quantum world, the physical states are interrelated, thus occurring phenomenon called entanglement. This study presents both a theoretical essay on the merits of quantum mechanics, computing, information, cryptography and quantum entropy, and some simulations, implementing in C language the effects of entropy of entanglement of photons in a data transmission, using Von Neumann entropy and Tsallis entropy.

Soil physical and microbiological attributes cultivated with the common bean under two management systems

Agricultural management systems can alter the physical and biological soil quality, interfering with crop development. The objective of this study was to evaluate the physical and microbiological attributes of a Red Latosol, and its relationship to the biometric parameters of the common bean (Phaseolus vulgaris), irrigated and grown under two management systems (conventional tillage and direct seeding), in Campinas in the state of Sao Paulo, Brazil. The experimental design was of randomised blocks, with a split-plot arrangement for the management system and soil depth, analysed during the 2006/7 and 2007/8 harvest seasons, with 4 replications. The soil physical and microbiological attributes were evaluated at depths of 0.00-0.05, 0.05-0.10, 0.10-0.20 and 0.20-0.40 m. The following were determined for the crop: density, number of pods per plant, number of beans per pod, thousand seed weight, total weight of the shoots and harvest index. Direct seeding resulted in a lower soil physical quality at a depth of 0.00-0.05 m compared to conventional tillage, while the opposite occurred at a depth of 0.05-0.10 m. The direct seeding showed higher soil biological quality, mainly indicated by the microbial biomass nitrogen, basal respiration and metabolic quotient. The biometric parameters in the bean were higher under the direct seeding compared to conventional tillage.

Life cycle assessment applied to municipal solid waste management: a case study

This study analyzes the environmental performance of the Municipal Solid Waste Management System (MSWMS) of Piedade, São Paulo, from a systemic perspective. A life cycle assessment (LCA) technique was applied according to an attributional approach to evaluate both the current operational situation and different prospective scenarios, which were devised based on the application of targets for recycling dry and wet waste suggested by the pre-draft version of the Brazilian Plan for Solid Waste. The life cycle impact assessment method EcoIndicator 99, in association with normalization and weighting procedures, was used to conduct the analysis. It was observed that the adoption of goals of 30%, 50% and 70% for recovering of the recyclable dry waste, resulted in improvement of the environmental performance of the waste management system under analysis, respectively of 10%, 15% and 20%. It was also possible to detect an evolution in the order of 54% in reducing impacts resulting from the adoption of targets for composting. LCA proved to be effective for the evaluation of the environmental performance of MSWMS-Piedade. However, for future evaluations, the attributional approach should be replaced by the methodological practice of substitution to enable the avoided burdens to be considered in estimations of the environmental performance municipal solid waste management systems.

Productivity, Leaf Nutrient Content and Soil Carbon Stocked in Agroforestry and Traditional Management of Maize (Zea mays L.)

The aim of the work was to evaluate the productivity, leaf nutrient content and soil nutrient concentration in maize (Zea mays L.) grown in sequence with black oats (Avena strigosa Schreb.) under Leucaena diversifolia alley cropping agroforestry system (AFS) and traditional management system/sole crop (without trees-TS), after two years of cultivation following a randomized block design. The experiment was carried out in the Brazilian Association of Biodynamic Agriculture, in Botucatu—S?o Paulo, Brazil. Treatments were: control (C), chemical fertilizer application (F), biomass of L. diversifolia alley cropping application (B), biomass of L. diversifolia alley cropping + chemical fertilizer application (B + F). In the second year of management it was observed that black oat yield was higher in treatments B + F and F with significant difference in relation to the others treatments in both systems, followed by treatment B. Between systems, only treatment B showed significant difference, with higher yield value corresponding to AFS, reflecting the efficiency of AFS to promote soil fertility. Maize production presented the second year of cultivation an increasing trend in all treatments in both production systems. This result may be due to the cumulative effect of mineralization and maize straw and oats, along the experiment. How productivity was higher in the AFS system, could also be occurring effect of biological nitrogen fixation, water retention and reduction of extreme microclimate through the rows of L. diversifolia. Comparing the AFS and TS, it was observed that the concentration of N in leaf tissue was higher in the AFS treatments, probably due to nitrogen fixation performed through the rows of L. diversifolia, that is a nitrogen fixing tree species. After two years, carbon stocked in soil show higher values in the treatments biomass + fertilizer and biomass application, in both systems, AFS and TS.
