In the capital market the information are used as subsidies for the decision making of investors, among the main highlights are the economic, political, accounting and relating nature to the financial results of companies which have stocks traded at Stock Exchanges. In this perspective, it is essential that the agents involved especially brokerage companies establish management processes that contain a set of criteria for the organization and treatment of information collected in newspapers, news agencies and the companies that trade in stocks. Thus, it is essential to establish rigor in relation to recovery mechanisms of such information, which requires more than technology, because actions are necessary that will propitiate the informational content are made available with consistency, clarity and trustworthiness, so as that users can retrieve them in a timely manner. Furthermore, those processes should provide the efficient use of the information retrieved by users, so that they can use them aiming to subsidize the decisions of sale or purchase shares. Considering that the information systems are responsible for the information dissemination in the framework of capital market, it is necessary to present requisites that contemplate the set organization, treatment, retrieval and use of information. That way, we sought to evidence in this paper these issues, utilizing as a premise the elements proposed by Guimarães (2003) from the perspective of the information environment of a values brokerage companies reflecting through the model used, how these companies realize their work considering the dimensions of the documentary analysis, informational treatment, and the instruments for retrieval and use of information.

A great competition between companies happens nowadays, due to, among other factors, the globalized economic system, the growing consumer demand and the technological advances. This fact implies the need for fast and efficient tools in decision making. A validated simulation model is able to perform this task. Thus, it was parameterized a simulation model of a fuel distribution terminal. It is a complex system because of its great variability. The model´s data input were collected, however the model was not statistically validated, in other word, does not adequately represent the real system. A search was made for the possible causes of this fact: dividing the compartments of tanker trucks, data collection may have been insufficient, inefficient model for unloading of biofuels

With the imposition of the suspension of production and subsequent banning of incandescent light bulbs will be necessary to replace it by other more energy-efficient. Although the main alternative is the compact fluorescent lamp, the environmental impact caused by it due to incorrect disposal and the amount of harmonics included in the network resulting in losses related to the quality of electric power system makes them sought new alternatives for lighting systems that are efficient and have low environmental impact. In this context, the LED (Lighting Emitting Diode), based on solid-state components, is presented as an option for new projects and replacement of existing lighting. In this work we studied aspects of energy, environmental and economic impacts of a possible replacement of conventional lighting systems for new technology. From laboratory tests and surveys of the costs of different types of lamps used for residential lighting, we performed a comparative analysis considering energy and economic aspects which showed that the LED technology, but has a high initial investment, it is best when power quality and environmental preservation are relevant factors in decision making for the choice of technology to be used in the lighting system

In 2004 two trading environment for contracts of purchase and of electricity energy were established, the Regulated Contracting Environment (RGE) and the Free Contracting Environment (FCE). In the first one, consumers can only buy their energy directly from local electricity distribution, and in the second one, consumers can choose their delivery, amount and type of energy that they will burn through bilateral contracts. Thus, before deciding to migrate to the FCE, it is necessary understanding the rules of marketing, the risk involved and the economic viability of the two markets so can determine which environment has more benefits to the consumer. This paper aims to offer tools to support takeover decision of potentially free costumers, who have the option to migrate to market in order to evaluate the benefits and disadvantages of each market. This paper has also considered the new rules of the third rate cycle, where consumers can opt for green tax. The methodology presented is based on calculations of spending with energy and the risk of flag in captive market and free market in one year

Nos últimos tempos o futsal tem se desenvolvido muito rapidamente, modificando seu caráter amador e aumentando o número de participantes e de país que o praticam. Essas mudanças têm causado melhoras nas ações técnicas e táticas dos jogadores, além de aumento na rapidez do raciocínio para a tomada de decisão, além da forma física (necessidade de uma capacidade aeróbica e de uma massa muscular desenvolvidas para a melhora do desempenho em quadra). Um dos responsáveis pelo desenvolvimento do futsal foram os avanços na tecnologia que através de ferramentas específicas facilitam e auxiliam na evolução da equipe no decorrer dos treinamentos e jogos. Desta forma, as equipes conseguem controlar os aspectos técnicos, táticos, físicos e psicológicos que ocorrem com a equipe, podendo obter dados quantitativos e qualitativos que ajudam a alcançar melhor performance dos atletas e da equipe. Um exemplo destas ferramentas é o “scout”, o qual se mostra um instrumento viável para uma avaliação técnica e tática de uma equipe. Através desta ferramenta pode-se avaliar detalhes importantes do jogo como o número de finalizações (eficiência do ataque), local de finalização, número de desarmes, passes certos e errados, tanto da sua equipe como também da equipe adversária. Com isso, com o auxilio do “scout” independentemente da tecnologia que se utilize, mais avançadas como softwares específicos ou menos sofisticadas como planilhas de anotações, consegue-se além de realizar uma avaliação individual da condição técnica do atleta também analisar os sistemas de defesa e ataque de uma equipe.Assim, o objetivo deste estudo foi de verificar e comparar a relação de acerto e erro das ações de passe, desarme e finalização apresentado pelas equipes vencedoras e as perdedoras de partidas de futsal, vislumbrando...(Resumo completo, clicar acesso eletrônico abaixo)

The importance of the capital market to Brazilian economic development, linked to the the fragility of a theoretical framework on the issue, case for developing this research. The agents operating in the capital market seek security and confidence for decision making on their investment in that sense we seek to address the concept and values of Corporate Governance to pay in the Brazilian capital market. The Corporate Governance, in its essence, is the system by which companies are directed and monitored, involving the relationship between shareholders and the board of companies, as well as a set of mechanisms and factors intended to minimize market failures. Seeking to confirm adherence to a more advanced system of corporate governance can result in a favorable financial performance, companies were investigated operating in the financial sector (intermediation, various services and insurance), listed by BM&FBOVESPA. The stock market ranks the corporate governance systems in three levels: Level 1 (rudimentary), Level 2 (intermediate) and New Market Level (advanced). To earn the impact of different levels of Corporate Governance for the outcome of the selected companies were calculated and analyzed accounting ratios of profitability, capital structure and liquidity from the Standardized Financial Statements (DFP), base year 2011, 2012 and 2013

This research aimed to develop a Fuzzy inference based on expert system to help preventing lameness in dairy cattle. Hoof length, nutritional parameters and floor material properties (roughness) were used to build the Fuzzy inference system. The expert system architecture was defined using Unified Modelling Language (UML). Data were collected in a commercial dairy herd using two different subgroups (H-1 and H-2), in order to validate the Fuzzy inference functions. The numbers of True Positive (TP), False Positive (FP), True Negative (TN), and False Negative (FN) responses were used to build the classifier system up, after an established gold standard comparison. A Lesion Incidence Possibility (LIP) developed function indicates the chances of a cow becoming lame. The obtained lameness percentage in H-1 and H-2 was 8.40% and 1.77%, respectively. The system estimated a Lesion Incidence Possibility (LIP) of 5.00% and 2.00% in H-1 and H-2, respectively. The system simulation presented 3.40% difference from real cattle lameness data for H-1, while for H-2, it was 0.23%; indicating the system efficiency in decision-making.
