Sustentabilidade de EES: contribuições e desafios do PITCPES/UFPA a partir da análise da Cooperativa dos Fruticultores de Abaetetuba COFRUTA

The study aimed to understand how the methodology of hatching contributes to the sustainability of economic enterprises in solidarity. For analysis, we developed a study on the social economy and the incubation methodology, based on the program of teaching, research and extension - Technological Incubator of Popular Cooperatives and Entrepreneurship Solidarity (PITCPES), and as the survey of the Cooperative of Fruit of Abaetetuba - COFRUTA. We started from the exploratory-descriptive approach in a qualitative and quantitative, in order to demonstrate the process of sustainability under the dimensions of different kinds such as: the economic dimension, social dimension, the political dimension, size and scale management training. Based on the analysis of these different dimensions was reached results as: first the recognition that the incubator contributes to the sustainability of COFRUTA, especially with regard to planning, control and the need to diversify production. However, there was suggestion of cooperative for training and technical assistance is continued, to the extent that the performance of projects under the base leaves gaps for the learning and application of social technologies required to the Incubator. It also concluded that the dissertation contributes to the team of the incubator can assess their strengths and weaknesses in their performance

Previsão do índice bovespa por meio de redes neurais artificiais: uma análise comparada aos métodos tradicionais de séries de tempo

Forecast is the basis for making strategic, tactical and operational business decisions. In financial economics, several techniques have been used to predict the behavior of assets over the past decades.Thus, there are several methods to assist in the task of time series forecasting, however, conventional modeling techniques such as statistical models and those based on theoretical mathematical models have produced unsatisfactory predictions, increasing the number of studies in more advanced methods of prediction. Among these, the Artificial Neural Networks (ANN) are a relatively new and promising method for predicting business that shows a technique that has caused much interest in the financial environment and has been used successfully in a wide variety of financial modeling systems applications, in many cases proving its superiority over the statistical models ARIMA-GARCH. In this context, this study aimed to examine whether the ANNs are a more appropriate method for predicting the behavior of Indices in Capital Markets than the traditional methods of time series analysis. For this purpose we developed an quantitative study, from financial economic indices, and developed two models of RNA-type feedfoward supervised learning, whose structures consisted of 20 data in the input layer, 90 neurons in one hidden layer and one given as the output layer (Ibovespa). These models used backpropagation, an input activation function based on the tangent sigmoid and a linear output function. Since the aim of analyzing the adherence of the Method of Artificial Neural Networks to carry out predictions of the Ibovespa, we chose to perform this analysis by comparing results between this and Time Series Predictive Model GARCH, developing a GARCH model (1.1).Once applied both methods (ANN and GARCH) we conducted the results' analysis by comparing the results of the forecast with the historical data and by studying the forecast errors by the MSE, RMSE, MAE, Standard Deviation, the Theil's U and forecasting encompassing tests. It was found that the models developed by means of ANNs had lower MSE, RMSE and MAE than the GARCH (1,1) model and Theil U test indicated that the three models have smaller errors than those of a naïve forecast. Although the ANN based on returns have lower precision indicator values than those of ANN based on prices, the forecast encompassing test rejected the hypothesis that this model is better than that, indicating that the ANN models have a similar level of accuracy . It was concluded that for the data series studied the ANN models show a more appropriate Ibovespa forecasting than the traditional models of time series, represented by the GARCH model

Turismo cultural na ZEPH-Ribeira: possibilidades e limitações

Considering that urban interventions, planned and executed recently at Natal, RN, should put Ribeira - one of the town centers - in the new limits of the expanded center of the city, this work examines the use of this new accessibility for the benefit of the development of an infrastructure to support a type of tourism currently seen as an alternative to diversification into areas dominated by entertainment tourism (the case of Natal). A local with city's traditional cultural facilities and holder of a set built that is a synthesis of the images of the neighborhood, it fears that this increase in the potential for movement and flows of use stimulate speculation and deployment of a bulk type of activity incompatible with the preservation the architectural heritage. Important economy for the city, tourism has been showing a factor propellant processing urban related changes in accessibility. It is argued that cultural tourism, often used in plans and projects of revitalization across the country, may be factor for sustainable development and conserve the assets, and contributes to the process of revitalization of the historic cultural center as Ribeira. Intended to illustrate the need to consider other information that might help in the revitalization of the neighborhood, this research presents the offer cultural tourism of Ribeira and identifies and maps certain physical attributes that, combined with functional attributes, can stimulate or inhibit the diversity and vitality in the region

Interesses da habitação social : políticas e processos no Rio Grande do Norte

En 2003, le gouvernement brésilien (gestion Lula) a initié une nouvelle phase dans son histoire de l habitation, en intensifiant les constructions de logements sociaux au Brésil. Un tel accroissement a eut des répercussions tant en ville comme à la campagne, et fût marqué dans le Rio Grande do Norte, par la production a grande échelle d ensembles d habitations, dans les programmes de Gouvernement. Afin de viabiliser ces transformations, des instruments politiques, financiers et de gestion ont étés articulés conjointement, utilisant la répétition d une typologie d édification, comme modèle, accompagnée de la reproduction d une morphologie dans les constructions de logements sociaux. Afin de comprendre ce processus nous introduisons une recherche urbanistique et socio-économique du problème du logement social au Brésil, en cherchant à mettre en relation les aspects techniques avec les questions historique, professionnelles et culturelles, éléments complémentaires. Notre analyse cherche a identifier comment les politiques de gestion et financement officielles (administrées dans sa grande majorité par la Caisse Économique Fédérale -CEF-), influencent le processus de conception de projets, en provoquant les répétitions de type/morphologiques, déjà citées. Basée sur l observation directe au cour de deux expériences différenciées pour du logement social en milieu rural, au Rio Grande do Norte, nous montrerons aussi certaines limitations et possibilités des acteurs sociaux, face aux agents et politiques officielles pour le logement social au Brésil, proposant des solutions alternatives standardisées qui caractérisent le résultat des projets financées et gérés par la CEF.

Estudo comparativo de dois tipos de cultivo: monocultivo (camarões) versus cultivo integrado (algas/camarões)

The integrated culture of seaweed and aquatic animals is an ancient practice in Asian countries. The expansion of this practice to western countries is consequence of the recognition of this system as a sustainable alternative that allows economical diversification and mitigation of environmental impacts generated by effluents of aquaculture. This study evaluated the growth of the seaweed Gracilaria caudata and of the shrimp Litopenaeus vannamei in monoculture (shrimps) and integrated culture (shrimps and algae) systems, and accessed the effect of the seaweed in the water quality. There were two treatments in the experiment: monoculture (shrimps) and integrated culture (shrimps/ algae). The organisms were cultured in 6 aquaria (10L) filled with seawater (35.0±0.0 PSU and 28.1±0.4°C) for 28 days. The nutrients of water (PO43-, NH4+, NO2-, NO3- and DIN), the biomass and the relative growth rate (RGR, % day-1) of seaweed and shrimps were measured weekly. The parameters pH, temperature, salinity and dissolved oxygen were measured daily. The concentration of NH4+ in integrated culture (62.8±25.2µM) was lower (Mann-Whitney p<0.001) than in monoculture (85.6±24.3µM). The mean of PO4- in monoculture (10.4±4.6µM) was markedly higher (Mann-Whitney; p=0.024) than that in integrated culture (8.7±4.1µM). The level of dissolved oxygen in integrated culture (6.0±0.6mg/L) was higher (t-Student; P=0.014) than that in shrimp monoculture (5.8±0.6mg/L). The mean values of the parameters pH, NO2-, NO3- and DIN were 7.5±0.2, 10.1±12.2µM, 24.5±3.2µM and 120.17±30.76µM in monoculture, and 7.5±0.2, 10.5±13.2µM, 27.4±3.5µM and 100.76±49.59µM in integrated culture. There were not differences in these parameters between treatments. The biomass and RGR of seaweed reached 15.0±1.9g and 7.4±2.8% day-1 at the end of the experiment. The performance of shrimp was favorable in monoculture (1.5±0.8g; 5.7±1.6% dia-1) and in integrated culture (1.5±0.7g; 5.2±1.2% dia-1), and the rate of survival was 100% in both treatments. The tolerance and favorable performance of Gracilaria caudata suggest that this seaweed might be integrated into shrimp (Litopenaeus vannamei) culture systems

Parâmetros citogenéticos de espécies comerciais de carangidae (perciformes), com vistas a sua empregabilidade na conservação biológica e piscicultura marinha

Worldwide, families Carangidae and Rachycentridae represent one of the groups most important commercial fish, used for food, and great potential for marine aquaculture. However, the genetic bases that can underpin the future cultivation of these species, cytogenetic between these aspects are very weak. The chromosomal patterns have provided basic data for the exploration of biotechnological processes aimed at handling chromosomal genetic improvement, such as induction of polyploidy, androgenesis and ginogenesis, as well as obtaining monosex stocks and interspecific hybridizations. This paper presents a comprehensive cytogenetic survey in 10 species, seven of the family Carangidae and the monotypic family Rachycentridae. Classical cytogenetic analysis and in situ mapping of multigene sequences were employed, and additionally for the genus Selene and morphotypes of Caranx lugubris, comparisons were made using geometric morphometrics. In general, conservative species exhibit a marked chromosome number (2n=48). Although present in large part, different karyotypic form, retain many characteristics typical of chromosomal Order Perciformes, the high number of elements monobrachyal, Ag-NORs/18S rDNA sites and heterochromatin simply reduced, preferably centromeric. The main mechanisms involved in karyotypic diversification are the pericentric inversions, with secondary action of centric fusions. In addition to physical mapping and chromosome detail for the species are presented and discussed patterns of intra-and interspecific diversity, cytotaxonomic markers. This data set provides a better understanding of these patterns caryoevolutyonary groups and conditions for the development of protocols based on Biotechnology for chromosomal manipulation Atlantic these species

Formação em odontologia: um estudo sobre as clínicas integradas em cursos do Brasil

Dental education is going through important changes in preparing workers to meet the needs of the society and the labor market. For that reason, we studied the offering of comprehensive dental care clinics in Brazil with the aim of encouraging future curriculum changes focused on the training of general dental practitioners. An email questionnaire on educational organization and comprehensive care clinics of undergraduate programs was sent to each academic dental affairs dean. Sixty-seven (41.6%) dental schools agreed to participate. We observed that curriculum changes have contributed to modify the format of comprehensive care clinics. This was felt mainly (88,1%) with regards to workload and course offerings in different levels of the dental curriculum, thereby creating a favorable environment for generalist training. Most schools shared the following characteristics: clinical procedures were being prioritized according to level of complexity (95,5%), students were having the chance to attend courses in other programs (37,3%), and attempt to diversify teaching methods was being challenged (58,2%). Although progress in combining teaching and clinical services was reported by 83,6% of schools, most clinical procedures were still being performed intramurally (50,7%) in partnership with public service. There was also improvement in clinical mentorship due to the hiring of instructors qualified to work in comprehensive care clinics and with aptitude to supervise a wider range of dental procedures (58,2%). Further changes to Brazilian comprehensive care clinics should hence be encouraged and intensified to ensure appropriate generalist training for dental practitioners

Desvendando o padrão alimentar de famílias rurais: o que tem no prato?

That work looked for to point out the different conceptions on the family agriculture and the established self-consumption practices inside the unit of production. Hypothesis: due to the conditions, more and more restricted of producing for the self-consumption, the rural families are more favorable present her situation of alimentary insecurity as severe as for the urban families, unlike what he/she defends. The research was accomplished in three states of the Northeast: Paraíba; Rio Grande do Norte and Sergipe. The results revealed that among the main factors that expose those families to situations of constant alimentary vulnerability are had: the low quality of the alimentary consumption in what concerns the readiness, to the diversification and mainly, to the accessibility. The analyses can be to subsidize a reflection concerning the alimentary pattern of families rural front to the precepts of Food and Nutrition Security (FNS) politics

Cara e coroa: O PRONAF B e os impactos na ocupação rural do município de Ceará-Mirim

The present work deals with study on the National Program of Reinforcement of Familiar Agriculture, Group B, referring it offers of agricultural credit the agriculturists who possess familiar prescription until R$ 2,000, 00, and its impact in the agricultural occupation of the city of Ceará-Mirim. From theoretical referencial regarding the agricultural occupation, it collects of data, application of questionnaires between the beneficiaries of PRONAF B and interviews with the involved actors, it was made possible ascertainment of the hypothesis of that the program in this modality of credit, is capable to provide only to the maintenance or diversification of the occupation in the familiar unit and not it generation of remunerated occupation not familiar. This research disclosed to the diverse possibilities of use of the credit and its impact in the agricultural occupation, exactly when it is deviated for other purposes not waked up next to the financial institution, generating impacts not waited, however positive. When destined to the waked up end, still new forms appear of way occupation to complement it the deriving familiar prescription of the main activity. Unable to discard the rise even though very small and informal, non-family gainful occupation. The knowledge is added of that exactly ahead of the easinesses of access to the social base of the program, many familiar agriculturists still find difficulties in the approval of the which had credit, on the other hand, the requirements of the financial institutions

Desenvolvimento energético e energia eólica na ordem jurídica do Brasil: aspectos Institucionais e Socioambientais

A conformação do desenvolvimento propugnado pela Constituição Federal de 1988 como objetivo fundamental da república, certamente perpassa pela racionalização das questões energéticas e pela diversificação da matriz nacional enquanto estratégia de aprovisionamento. O desenvolvimento energético em toda a sua complexidade deve ser alicerçado não em uma relação de contraposição à sustentabilidade, mas cooperativismo normativo e de projetos sociais que objetivam a melhorias para a população nestes dois seguimentos. O advento das energias renováveis nesse contexto se consolida como uma alternativa viável, apesar do tratamento dado pela Lei Maior ao tema ter sido apenas com relação à geração em pequena escala. A interpretação sistemática dos postulados da ordem econômica e as exigências da sociedade estimulam o aproveitamento dos potenciais renováveis em escala comercial e regional, além do fortalecimento nos segmentos de autoprodução e produção independente. Dentre as energias tratadas como prioritárias neste contexto, a eólica revela-se como carecedora de aprofundamento das estruturas dogmáticas de sua positivação, que envolve um vasto manancial de regras pulverizadas na regulação econômica do setor elétrico e no controle ambiental. Esta textura submete os empreendimentos elioelétricos aos instrumentos da política nacional do meio ambiente e às determinações do poder concedente dos serviços de energia elétrica, responsável pela pormenorização da geração, transmissão, distribuição e comercialização de energia, independentemente da fonte primária utilizada no processo de transformação. Tratar destas questões com o compromisso na formulação de raciocínios críticos e propositivos, especialmente acerca de temas como a liberdade energética e controle de mercado, é imperioso para superar juridicamente as limitações presentes inclusive no discurso da delimitação de marcos normativos adequados. Havendo vantagens ambientais, tecnológicas e comerciais na exploração da energia cinética do vento como propulsora do desenvolvimento no modelo civilizatório estabelecido, cumpre também ao Estado dar a sua contribuição setorial na forma de incentivos, desburocratização e aprimoramento do modelo concorrencial. O estudo adota os métodos histórico-evolutivo, dialético e sistêmico de abordagem, encarando as hipóteses formuladas no aspecto das consequências multilaterais que as soluções encontradas apontam, exigindo que a estabilização de expectativas sociais por parte do ordenamento jurídico não ignorem o sentido material cognitivamente aberto do desenvolvimento. Hodiernamente, a perspectiva de desenvolvimento energético alia tendências econômicas e tecnológicas em favor das fontes alternativas mais eficientes, revelando a energia eólica como uma representante adequada em termos pragmáticos de normatização e preservação ambiental

A diversidade de lagartos na Caatinga é mediada pelos térmitas?

Intending to explain the extraordinary lizard coexistence levels found in Australian deserts, Morton & James (1988) figured out a hypothesis which defends that the termite diversity would bring about lizard radiation. This study aims to verify the validation of that hypothesis in Caatinga lizard assemblages. This study also objectives verifying if the termite defense mechanisms influence their consuming levels by lizards and if this pattern differs between different lizard lineages. Termites were collected using a standardized sampling protocol of termites. Besides using haphazard sampling, we collect lizards with 108 pitfall traps in each area. Intending to check the linkage between the termite and lizard assemblages, the lizard stomach contents were analyzed and then a canonical correspondence analysis was performed. The presence of nonrandom patterns of diet overlap among the lizard species was also examined. Aiming to check if the defense mechanisms of termite influence their consuming pattern by lizards it was performed a laboratory experiment where termite with different defense mechanisms were offered to lizards of two different lineages. We verified that lizard assemblages do not consume termites according to termite abundance in ecosystems. Furthermore, mean niche overlap lizard species did not differ significantly from that expected by chance. We found that termite chemical defense mechanism does influence the termite s pattern consuming by lizards. These results do not corroborate premises which support Morton & James hypothesis (1988) and point out that lizard do not chose termites based on their abundance, but, trying to avoid consuming termites which exhibit chemical defense mechanisms. This defense mechanism, however, may not be the only explanation to patterns of termite s consuming by lizards.

Relações internacionais: o comércio exterior do Brasil e Rio Grande do Norte no período de 1999 a 2008

The period post-war promoted several changes in relations economic, political and social world. Since then, a new division international of labor has delineated, with the great growth of Asian countries. In the field of international relations, the world still appears to transition is not completed because the old institutions were not replaced by new ones and the power of the United States as a major capitalist country remains unshaken, even with the emergence and strengthening of new economic global blocs. With globalization, Brazil emerges with more intensity in the face of new issues global, although its share in transactions trade global hasn‟t changed accordingly. In this sense, the objective of this dissertation is to examine, in a descriptive and critical the development of international relations and trade of Brazil and Rio Grande do Norte with the main blocs in the world from 1999 to 2008. As a secondary objective: to identify the assumptions theoretical that underpinned the decisions governments of the FHC and Lula, in particular, the interference of these terms in international relations and foreign trade. Adopted as the procedure methodological the literature review of the subject, as well as collection and processing of the data of foreign trade. During the Cardoso government has undergone the substantial growth in imports, as part of the economic policy of anti-inflationary, generating large deficits trade. From the first to the second term, with the inflection of exchange rate policy the country has resumed surpluses trade. The choice of government of the autonomy participation increased the relative share of the traditional blocks in total foreign trade and reduced the share of MERCOSUL. In the Lula government, there is the maintenance of some elements of the economic policy of the previous government and the partial shift in the conduct of foreign policy, with the option of autonomy through diversification, raising its stake on the blocks and other emerging countries in total foreign trade Brazilian and reducing the contribution of the traditional blocks such as NAFTA and the European Union. A trend observed in the previous government and deepened in the Lula government was the growth in commodity exports and the decline of manufactured products, confirming the model of conservative insertion of Brazilian exports. The Rio Grande do Norte followed the trend Brazilian in the growth of foreign trade, including in participating conservative, given that the products exported by the state are basically coming from horticulture irrigated and agribusiness. However, in the aspect of destination export, the state followed trajectory distinct from that in the Lula government, with the deepening of trade relations with traditional blocks, especially with the European Union and NAFTA

Reconfigurações industriais das regiões metropolitanas do Nordeste: uma análise a partir do emprego formal

Industrial development experienced by Brazil from the 1950s, changed the concentration of population in the country. The process of development of domestic industry, concentrated in urban areas, crowded growing portion of the population.The Southeast region during the first stage of industrialization driven by the state, with the implementation of Plan goals, captained the major industrial projects implemented in the period and became the main industrial center of the country.In the decade from 1960 to 1980 the state action was marked by numerous regional development projects, softening the industrial concentration and Brazilian investment redirected to the Northeast.The second National Development Plan implemented in the 1970s led to major investments Northeast.This period marked the widespread urban growth and institutionalization of the first metropolitan areas in Brazil.The change of this developmental process is altered with the fiscal and financial crisis of the state in the 1980s and 1990s and spending cuts aimed at national development, reorienting the economy to liberal policies of economic liberalization and reduction of activity in the economy.Industrial policy was relegated to local development plans from the 1990s to the federating units fitting the wide use of tax incentives, the "war tax" to the continued industrialization process.In this context of the national economy work seeks to analyze the industrial setting in the metropolitan areas of Fortaleza, Recife and Salvador between 1995 and 2010.Although the metropolitan areas of Fortaleza, Recife and Salvador are the main urban centers of the Northeast, responsible for the advancement of industrial development, reconfigurations occurred between 1995 and 2010 by changing the level of industrial specialization built by regional division of labor in these regions.The work will be carried out by the method of descriptive analysis of the literature review on regional and urban development.Constitute quantitative method as the secondary data analysis of formal employment from the Annual Social Information (RAIS) Ministry of Labour and Employment (MTE).Using data RAIS / MTE analyzes the industrial specialization index using the Locational Quotient (LQ).Thus, it is assumed as a parameter analysis QL> 1, when the region has become specialized in a particular sector or QL <1, when the region does not have expertise in industrial sector analyzed.The conclusion of study indicates that there was in these metropolitan areas maintained the same bias hub.Fiscal policies, the states, was not successful in diversifying the productive structure and the Northeast region itself.This result is demonstrated by the need and dependence on state investments in the region to promote development.Industrial policies of recent years have been positive to meet the objectives of employment generation, but there must be specific policies for better diversification of production, in addition to integrating the economy of the Northeast sector and regionally
