Application of systemic vision in the educational process
(Problems of Management in the 21st Century, 2012) Queiroz, Jamerson Viegas; Lima, Nilton Cesar; Penedo, Antonio Sergio Torres; Oliveira, Marcio Mattos Borges de; Oliveira, Sonia Valle Walter Borges de
As the sophistication of technology is increasing, also increased the demand for quality in education. The expectation for quality has promoted broad range of products and systems, including in education. These factors include the increased diversity in the student body, which requires greater emphasis that allows a simple and dynamic model in the provision of education. For this reason, a formalized methodology known as systems theory is often applied in the industry as a management instrument, or in other words, known as systems management. The management of educational systems would be adherent to ally in reducing failure rates and quality improvement. This is possible in complex learning systems scale. Accordingly, this article aims to discuss some implications of trying to use the systems management as modern teaching methodology
Characterization of demand for hydrous ethanol fuel in Brazil
(Business Management Dynamics (BMD), 2012-09) Queiroz, Jamerson Viegas; Lima, Nilton Cesar; Oliveira, Sonia Valle Walter Borges de; Oliveira, Márcio Mattos Borges de
The purpose of this study is to characterize the demand of hydrous ethanol fuel in the Brazilian market. This research seeks to present the developments, challenges and new market scenarios of hydrous ethanol. The theoretical part of the object design research, hydrated ethanol demand, seeking the understanding of the market of ethanol in its emergence in the country via Proálcool, as well as its rise and fall, the challenges and new scenarios from the flex fuel vehicle. The contextualization of ethanol fuel on the domestic market under as characterized the offer, its technologies and its main thrusters in the diffusion of the fuels market is not object of investigation. The work has as investigative methodology of exploratory and descriptive, explanatory, whose method is qualitative, in which research provides reflections and understanding from the understanding of hydrated ethanol fuel demand in the Brazilian market. the evidence considered in the study demonstrated through a qualitative analysis, which allowed demand conditions varied market mutation, since its emergence times up to the present time, that began with the economic pressures arising from the volatility of prices of oil barrels until the time the flex fuel technology redraws a new scenario in the market of hydrous ethanol
Formation of the hydrated ethanol's prices in the combustible Brazilian market
(Society for Business Research Promotion, 2012) Lima, Nilton César; Oliveira, Sonia Valle Walter Borges de; Queiroz, Jamerson Viegas; Furukava, Marciano; Queiroz, Fernana Cristina Barbosa Pereira
The current study investigated the formation of the hydrated ethanol in the Brazilian fuel market, comprising costs, scale economy and marketing, economical and social factors. The research provides comprehension and reflections about the market, explaining, by means of the multiple linear regression models that the prices paid to the producer, distributor and production costs. There are evidences relative by other variables, with low linear coefficient, that complemented with the quality analysis, guide and give complexity to the price formation. The tool Variable Analysis Statistics (Anova) made possible to identify the advantage of the price of the hydrated ethanol in relation to the gasoline C in the internal market. In this way, an extended reflection of the results permitted to analyze that the advantage of the hydrated ethanol usage in the Center-West region, occurs from variable fleet, distribution basis, tributes, production and number of producer mill. In relation to the prices paid to the producer, distributor and production costs as main explainable variable in the prices formation, there are evidences related by other variables, which for more that have been presented low linear coefficient, there ones have casual relation, if complemented with the qualitative analysis, the ones which, offer, demand, tributes and seasonality are, as examples, factors that guide and give the complexity to the price formation
