Gestão ambiental e competitividade: um estudo sobre os fatores que afetam a decisão de compra de produtos orgânicos na cidade de Teresina-PI

The organic products represent one of the main trends of alimentary consumption in the new century. In Brazil, the answer is already well representative which it becomes the country, as a great consuming and exporting market of products of LVF type. The objective of this research was to investigate the factors capable to influence the food consumer in its purchase decision of organic products in the supermarkets of Teresina, capital of Piauí State. The methodology was exploratory and descriptive, using survey, with closed and opened questions in 542 interviewed. The questionnaire was based on projected scales to evaluate the factors that can influence the purchase decision of organic products, whose variable had been grouped in the following groups: behavior, knowledge, interest, competitiveness, importance, barrier and profile. The used statistical techniques were descriptive analysis and multiple regression analysis. The results demonstrate interest of the population in paying more for the organic product, due to better quality of life, however it lacks to one better spreading and greater sensitization to attract these consumers. Some recommendations and proposals are presented after the results, as suggestions for future research

Gestão de resíduos sólidos: um estudo da conscientização ambiental em uma cidade do Brasil

The present study inserts on the international environmental thematic, approaching the integrated management of solid waste and the participation of the social actors in the search of the sustainable development. The awareness in combining it still describes a Selective Collection Program SCP of solid waste, in partnership with the municipal public power, in the development of joint actions that result in better alternatives of waste management in the urban centers, providing better life quality for the population and conservation of the environment. The aim of this research is to study problematic of the management of solid waste under the point of view of the environmental awareness and the participation of the population in a city of Brazil. In this matter, the target of the work is focusing on the strategy of solid waste management, through the attitudes and the respondents behaviors to aid in the making decision of the public manager related to the implantation of a selective collection program in Natal/RN. The methodology used in this work constitutes in the application of a questionnaire with scales of the type Likert being constituted of variables that compose the aspects of attitudes and of behaviors, besides a social-demographic scale. For analysis statistics is used the Pearson s Chi-Square Method in order to verify the dependence of the associations between the social-demographic variables and the attitude and the behavior ones. The results appear for a larger participation in a SCP, since this provides a better quality of life of the population (28,3 %), followed for offering a financial advantage (27,3%). Other results indicate the existence of the variables that exercise influence on the environmental awareness of the population to its demographic aspects

Fator de decisão na adoção de um sistema de micro-cogeração de energia a gás natural :um estudo em Hotéis três estrelas

The natural gas perform a essential paper, not only in primary sectors of energy, but also in others sectors of economy. The use natural gas will have expansion in Brazil, motivated by governmental decision to increase the participation of this fuel in the Brazilian energy matrix from 4% to 12% up until 2010. in order to reach the objective related to increase the consumption of natural gas in the energy matrix and to propose solutions to attend the electric requirements of heart and refrigeration, using natural gas as primary power plant. This thesis has a main objective to analysis the perception of businessmen of hotel sector about the feasability of investment with micro-cogeneration system by natural gas in their hotel in turistic sector, in Natal/RN. It s show a case for the hotels selected analyzing the actual knowledge of businessmen about alternative of new technology in generation of owner energy. There was make a interview using a standard form researching information about this topic.

Two of this canaries uses the project finance like option to make fasible this projects. The resulteis showed who businessmen has insecurity to make decision to put in office alone, or with a local company, and perhaps with a national company to perform for a alternative energy system, justifying, the alone feasability and without information by local businessmen. Apart from that, they are receptive for a option to put in office in micro-cogeneration configured in the settings using project finance

Reconhecimento de voz através de unidades menores do que a palavra, utilizando Wavelet Packet e SVM, em uma nova estrutura hierárquica de decisão

The automatic speech recognition by machine has been the target of researchers in the past five decades. In this period have been numerous advances, such as in the field of recognition of isolated words (commands), which has very high rates of recognition, currently. However, we are still far from developing a system that could have a performance similar to the human being (automatic continuous speech recognition). One of the great challenges of searches for continuous speech recognition is the large amount of pattern. The modern languages such as English, French, Spanish and Portuguese have approximately 500,000 words or patterns to be identified. The purpose of this study is to use smaller units than the word such as phonemes, syllables and difones units as the basis for the speech recognition, aiming to recognize any words without necessarily using them. The main goal is to reduce the restriction imposed by the excessive amount of patterns. In order to validate this proposal, the system was tested in the isolated word recognition in dependent-case. The phonemes characteristics of the Brazil s Portuguese language were used to developed the hierarchy decision system. These decisions are made through the use of neural networks SVM (Support Vector Machines). The main speech features used were obtained from the Wavelet Packet Transform. The descriptors MFCC (Mel-Frequency Cepstral Coefficient) are also used in this work. It was concluded that the method proposed in this work, showed good results in the steps of recognition of vowels, consonants (syllables) and words when compared with other existing methods in literature

Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil

The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning of precipitation. Thus, if the plot pollution removed, the remaining portion can be used for other purposes. This work has aimed to present the variation of water quality of two drainage basins in the city of Natal / RN-Brazil to support the implementation of drainage to consider the qualitative aspect, and identify potential for the use of water. The basins (M and C) are analyzed closed-type, are in the urban area, are predominantly residential occupation and its waters are used for detention ponds and infiltration. The samples were divided into three phases, the first two direct to final points in a basin and the third in traps distributed over the surface drainage. The parameters had been analyzed were pH, conductivity, dissolved oxygen, Color, Turbidity, COD, Ammonia, nitrite, nitrate, total phosphorus, orthophosphate, Sediments solids, total solids, chloride, sulfate, alkalinity, calcium, magnesium, sodium, potassium, Heavy Metals (Chromium, Cadmium, Lead, Zinc and Copper), Eschichia coli and total coliforms. The parameters studied showed high initial pollution load, events and located in different proportions, except nitrite, heavy metals and biological indicators. The size of the surface drainage and topographic its features influence the quality of water. However, the form of sampling is crucial in the qualitative study in the basin. The samplers developed at work, were generated economic and representative results. The urban rainwater presents organic faecal indicators. The runoff of water from both basins shows no risk of salinity and sodicity for use in irrigation, should be noted the content of chloride in the choice of method of irrigation

A utilização da informação contábil na atividade pecuária do Estado do Rio Grande do Norte: um enfoque nos demonstrativos gerados para tomada de decisão

This work deals with the cattle raising activity in Brasil, it´s importance for the stete of Rio Grande do Norte. A conceptual review is done regarding accounting information and considering it as an essencial input for economical and finantial decision making, related to the state cattle rainsing environment. It also aims to expose visions related to the role and the importance of Accounting as system that colects, treats and supplies managerial information. A brief historic of Accounting is done, emphasizing the Accounting Demonstration Structure and its use in the decision making process, as well as the contribution it has node for the cattle raising activity in Brazil. The research´s results show that accounting information is used partially in the finantial decision making process, and it is pointed out that the Inventory was the most relevant tool with 95,% of the cases, followed by the Income and Outlay reports with 85.0%,Production with 82,0% and Cost reports with 80,0%, the Demonstrative of the Cash Flow (DFC) with 82.5%, the Patrimonial Balance (PB) with 22.5%, and the Demonstrative of the Exercise Result (DER) with 20.0% of use. The research concludes that Accounting information is not throughly used in the economic and finantial decision making of the managers of cattle raising in the Rio Grande do Norte State, although, 95% of the sample consider then important. This may imply that there are diffilculties in measurement of the managerial decisions as well as the business whole

A fazenda pública em juízo: a anulação de decisão administrativa definitiva a favorável ao contribuinte

El tema elegido para este estudio la materia disertación sobre la viabilidad de la Tesorería a buscar refugio a la corte anuló la decisión administrativa firme, dictada en lugar del procedimiento administrativo, fiscal, cuando tal decisión no es favorable a la Administración Pública Fiscal, o favorable para el contribuyente . El cálculo de la cuota a pagar se debe a las actividades administrativas relacionadas jurisdicción de la Administración Pública de la finca conocida como la evaluación de impuestos. En este sentido, la puesta en marcha, analizados desde la perspectiva del derecho administrativo, puede calificarse de acto jurídico administrativo. Para la constitución de la puesta en marcha es posible realizar tres pasos: a) un acto en la preparación para el tema de los impuestos - la revisión y evaluación, b) el acto administrativo de la liquidación del impuesto en sí o la aplicación de sanciones administrativas, el procedimiento c) el impuesto administrativo. Realizó la inspección y la investigación se ha iniciado para formalizar el acto administrativo del propio lanzamiento. Después de la puesta en marcha, con el homenaje que se está abierto a los contribuyentes dentro de la composición del tributo rechazo en libertad, que ofrecerá desafío para lanzar. Este paso es iniciar el "procedimiento administrativo tributario." La etapa procesal se caracteriza por ser un procedimiento de investigación o control de la legalidad de los actos administrativos en los que el contribuyente para mostrar su descontento con el lanzamiento de lo ya realizado. La evolución de los actos que lleva a cuestiones de procedimiento de especial importancia para esta tesis es que la decisión final sobre el procedimiento administrativo de impuestos o el control de la legalidad del acto administrativo de la liberación. Idea que se debe tener es que la decisión final es poner fin a fin o destino del impuesto procedimiento administrativo. Aquí están las preguntas de la tesis doctoral, por ejemplo, usted puede cancelar la corte real hacienda de la decisión administrativa dictada por el Consejo Administrativo de Apelación Reder, cuando decisum que conduzca a la privada? ¿Cuáles son los efectos de la decisión final? Con fuerza de cosa juzgada o impedimento administrativo? Se opone a la revisión por el poder judicial? La decisión administrativa es un acto administrativo? Puede ser cancelada o revocada por el Poder Judicial? Dada la divergencia en la doctrina y la jurisprudencia trata de resolver el problema que lo llevan a la solución definitiva al respecto. El autor llega a la conclusión de la imposibilidad, por regla general, y la oportunidad, como excepción a la Tesorería para solicitar la anulación del impuesto de la decisión administrativa final ante el Poder Judicial

Aspectos constitucionais da anulação de decisão definitiva da administração pública federal no processo tributário

Cet article traite de la possibilité de proposer le Trésor à la justice pour annuler une décision administrative définitive sur les questions fiscales. Il s'agit d'un sujet qui s'oppose au principe de la vérité matérielle - qui doit prévaloir en cas d'impôt - avec une certitude morale représentée par la chose jugée administrative. Commence par le processus administratif d'impôt comme une garantie constitutionnelle du contribuable, insérée dans le panorama d une compétence adoptée dans la législation brésilienne en tant que pilier de l'Etat de droit démocratique. Met l'accent sur la position du Trésor avant l'autorité de la chose jugée administrative, ce qui démontre la fragilité de La décision finale sur les questions fiscales. Décrit les effets de la révision (ou de l'annulation) dês actes administratifs, en particulier la libération de l'impôt et de la décision administrative qui vise à le confirmer. Enfin, nous discuterons de la composition et la légitimité du contentieux administratif, en conclusion, avec le soutien de la prévalence d'un fait important dans le cãs d'impôt, est non seulement possible, mais le Trésor devrait examiner leurs propres actions si nécessaire

Sistemas computacionais espaço-temporais para toma de decisão em questões ambientais relacionadas à indústria de petróleo e gás

The area between São Bento do Norte and Macau cities, located in the northern coast of the Rio Grande do Norte State is submitted to intense and constant processes of littoral and aeolian transport, causing erosion, alterations in the sediments balance and modifications in the shoreline. Beyond these natural factors, the human interference is huge in the surroundings, composed by sensitive places, due to the existence of the Guamaré Petroliferous Pole, RN, the greater terrestrial oil producing in Brazil, besides the activities of the salt companies and shrimp farms. This socioeconomic-environmental context justifies the elaboration of strategies of environmental monitoring of that coastal area. In the environmental monitoring of coastal strips, submitted to human impacts, the use of multi-sources and multitemporal data integrated through a Spatio- Temporal Database that allows the multiuser friendly access. The objective was to use the potential of the computational systems as important tools the managers of environmental monitoring. The stored data in the form of a virtual library aid in making decisions from the related results and presented in different formats. This procedure enlarges the use of the data in the preventive attendance, in the planning of future actions and in the definition of new lines of researches on the area, in a multiscale approach. Another activity of this Thesis consisted on the development of a computational system to automate the process to elaborate Oil-Spill Environmental Sensitivity Maps, based on the temporal variations that some coastal ecosystems present in the sensibility to the oil. The maps generated in this way, based on the methodology proposed by the Ministério do Meio Ambiente, supply more updated information about the behavior of the ecosystem, as a support to the operations in case of oil spill. Some parameters, such as the hydrodynamic data, the declivity of the beach face, types of resources in risk (environmental, economical, human or cultural) and use and occupation of the area are some of the essential basic information in the elaboration of the sensitivity maps, which suffer temporal alterations.In this way, the two computational systems developed are considered support systems to the decision, because they provide operational subsidies to the environmental monitoring of the coastal areas, considering the transformations in the behavior of coastal elements resulting from temporal changes related the human and/or natural interference of the environment

Mamíferos do campus da Universidade Federal de Santa Maria (UFSM), Rio Grande do Sul, Brasil

O estudo foi desenvolvido no Campus da Universidade Federal de Santa Maria (UFSM), localizado na Depressão Central do Rio Grande do Sul, no bioma Pampa. Aqui uma listagem de mamíferos é apresentada e são discutidas a ocupação espacial e estratégias de conservação da mastofauna local. Entre novembro de 2001 e outubro de 2002 foram registradas 26 espécies nativas e duas espécies exóticas (Lepus europaeus e Mus musculus) de mamíferos, distribuídas em 14 famílias. A maioria das espécies registradas apresenta ampla distribuição, é comumente associada a áreas abertas e apresenta tolerância a distúrbios antrópicos. Entretanto, também foram registradas espécies consideradas raras ou ameaçadas no Estado do Rio Grande do Sul (Lontra longicaudis, Monodelphis dimidiata e Nyctinomops laticaudatus), para as quais são sugeridas estratégias de conservação. A baixa diversidade de espécies registrada no Campus pode estar relacionada à forte pressão de modificações antrópicas, à pequena extensão da área estudada ou a fatores históricos, já que a área de estudo é originalmente campestre (Pampa), tipo de ambiente que abriga menor diversidade de mamíferos que áreas de florestas nativas.
