Análise de volatilidade, integração de preços e previsibilidade para o mercado brasileiro de camarão

The present paper has the purpose of investigate the dynamics of the volatility structure in the shrimp prices in the Brazilian fish market. Therefore, a description of the initial aspects of the shrimp price series was made. From this information, statistics tests were made and selected univariate models to be price predictors. Then, it was verified the existence of relationship of long-term equilibrium between the Brazilian and American imported shrimp and if, confirmed the relationship, whether or not there is a causal link between these assets, considering that the two countries had presented trade relations over the years. It is presented as an exploratory research of applied nature with quantitative approach. The database was collected through direct contact with the Companhia de Entrepostos e Armazéns Gerais de São Paulo (CEAGESP) and on the official website of American import, National Marine Fisheries Service - National Oceanic and Atmospheric Administration (NMFS- NOAA). The results showed that the great variability in the active price is directly related with the gain and loss of the market agents. The price series presents a strong seasonal and biannual effect. The average structure of price of shrimp in the last 12 years was R$ 11.58 and external factors besides the production and marketing (U.S. antidumping, floods and pathologies) strongly affected the prices. Among the tested models for predicting prices of shrimp, four were selected, which through the prediction methodologies of one step forward of horizon 12, proved to be statistically more robust. It was found that there is weak evidence of long-term equilibrium between the Brazilian and American shrimp, where equivalently, was not found a causal link between them. We concluded that the dynamic pricing of commodity shrimp is strongly influenced by external productive factors and that these phenomena cause seasonal effects in the prices. There is no relationship of long-term stability between the Brazilian and American shrimp prices, but it is known that Brazil imports USA production inputs, which somehow shows some dependence productive. To the market agents, the risk of interferences of the external prices cointegrated to Brazilian is practically inexistent. Through statistical modeling is possible to minimize the risk and uncertainty embedded in the fish market, thus, the sales and marketing strategies for the Brazilian shrimp can be consolidated and widespread

Análise da gestão da cadeia de suprimentos de um supermercado varejista através da utilização do modelo SCOR

In the last decade the complexity of the environment in which organizations are embedded increased dramatically, having on one side the increasingly demanding consumers in regard to the quality and value of the product and the other companies with the need to reduce operating costs in order to achieve greater profitability, without this there is a downturn in growth or market share powers. In this context the necessity of effectively structuring actions relating to the line with the operational work processes so that business objectives are achieved organizational strategic planning, ensuring the competitiveness of the organization. This study aims to analyze how you have made the management of the supply chain in a grocery retailer in the light of guidelines of Supply Chain Management by using the SCOR model. For realization of this study a survey was needed, classified according to their goals, exploratory and descriptive as to its procedure, document, field and case study. Thus, the processing of data will be qualitative merit, using the thematic categorical analysis of Bardin (1977). Thus, to obtain data interviews together the operational and strategic management of a company that was named Supermarket Omega were performed. After analyzing the information obtained is perceived that there is an effort of the organization enhance its management of the supply chain. However, there is a lack of alignment between the various areas that compose it. About their work processes, we stress that the focus of the company is still very directed on sailing than profitability, although it is undergoing a transformation in its organizational culture However, records the existence of many improvement projects in developing. Thus, it can be noticed that there is some consistency between the assumptions of the SCOR model and applied within the supply chain Omega Supermarket, although a greater effort to better align with the model still needs to be studied

Uma metodologia para a análise do desempenho sustentável dos postos de revenda de combustível na cidade de Natal/RN, com o uso de data envelopment analysis-DEA

The increasing use of fossil fuels in line with cities demographic explosion carries out to huge environmental impact in society. For mitigate these social impacts, regulatory requirements have positively influenced the environmental consciousness of society, as well as, the strategic behavior of businesses. Along with this environmental awareness, the regulatory organs have conquered and formulated new laws to control potentially polluting activities, mostly in the gas stations sector. Seeking for increasing market competitiveness, this sector needs to quickly respond to internal and external pressures, adapting to the new standards required in a strategic way to get the Green Badge . Gas stations have incorporated new strategies to attract and retain new customers whom present increasingly social demand. In the social dimension, these projects help the local economy by generating jobs and income distribution. In this survey, the present research aims to align the social, economic and environmental dimensions to set the sustainable performance indicators at Gas Stations sector in the city of Natal/RN. The Sustainable Balanced Scorecard (SBSC) framework was create with a set of indicators for mapping the production process of gas stations. This mapping aimed at identifying operational inefficiencies through multidimensional indicators. To carry out this research, was developed a system for evaluating the sustainability performance with application of Data Envelopment Analysis (DEA) through a quantitative method approach to detect system s efficiency level. In order to understand the systemic complexity, sub organizational processes were analyzed by the technique Network Data Envelopment Analysis (NDEA) figuring their micro activities to identify and diagnose the real causes of overall inefficiency. The sample size comprised 33 Gas stations and the conceptual model included 15 indicators distributed in the three dimensions of sustainability: social, environmental and economic. These three dimensions were measured by means of classical models DEA-CCR input oriented. To unify performance score of individual dimensions, was designed a unique grouping index based upon two means: arithmetic and weighted. After this, another analysis was performed to measure the four perspectives of SBSC: learning and growth, internal processes, customers, and financial, unifying, by averaging the performance scores. NDEA results showed that no company was assessed with excellence in sustainability performance. Some NDEA higher efficiency Gas Stations proved to be inefficient under certain perspectives of SBSC. In the sequence, a comparative sustainable performance and assessment analyzes among the gas station was done, enabling entrepreneurs evaluate their performance in the market competitors. Diagnoses were also obtained to support the decision making of entrepreneurs in improving the management of organizational resources and promote guidelines the regulators. Finally, the average index of sustainable performance was 69.42%, representing the efforts of the environmental suitability of the Gas station. This results point out a significant awareness of this segment, but it still needs further action to enhance sustainability in the long term

Trajetória dos assentamentos rurais financiados pelo crédito fundiário no estado do Rio Grande do Norte: uma análise da experiência do assentamento da fazenda Paz no município de Maxaranguape/RN

The market-assisted land reform (RAAM) has been constituted as an alternative of agrarian reform funded by the Programa Nacional do Crédito Fundiário (PNCF). It is a policy of acquisition, distribution and use of Earth ideologically disseminated and funded by the World Bank in the context of productive insertion of landless workers. Accordingly, this study seeks to analyze the trajectory of rural settlements financed by this policy, seeking to understand what factors promote or limit the process of rural development of those settlements. To do so, take as a reference case study of the Assentamento da Fazenda Paz, in the municipality of Maxaranguape in the State of Rio Grande do Norte. From the methodological point of view, bibliographical and documentary research were used, in addition to visits to the settlement and semi-structured interviews with the settlers, trade union leaders, consultants and technicians linked to the project. Assuming the reports of respondents, initially constructs the hypothesis that informal and formal institutions present in the Assentamento da Fazenda Paz were unable to effectively coordinate the actions of the agents. The results obtained showed the existence of a very complex undertaking, with a total area of 607 hectares and 80 families settled, endowed with good quality water and irrigation infrastructure, with assets of approximately R$ 5 million reais. Experience experienced by the settlers understood the development of complex systems of production and marketing of fruits and vegetables, with an emphasis on the cultivation of papaya in an area of 45 hectares based on modern irrigation system and extensive use of technology. Collective management of production, marketing, revenue and costs stood out as a major challenge for the settlers and their representative organisations, i.e. the Community Association and the cooperative. From this observation it was possible to identify two moments on the trajectory of the project: the first, between 2007-2011, considered by respondents as successful, in which the integration of public policies and abundant input of revenue from the commercialization of the fruits da Paz, mainly through the sale of papaya and pineapple in national and international markets, allowed an average remuneration of R$ 800.00 reais to R$ 1,000 reais seated/monthIn addition to the production of vegetables and other types of products for sale and consumption; the second, from 2012, characterized as a failure, due to the discontinuity of the cultivation, production and marketing of fruits based on the collective bargaining model deployed. Important factors explain the discontinuity of the project, including the model of agriculture implemented, difficulties related to the management of production, marketing and finance the venture, in addition to the breach of trust between the Board of the cooperative and the associates and the distancing of the governmental organizations more directly responsible for the project. It is therefore concluded that we must to rethink rural development as a multidimensional phenomenon, requiring a broad engagement between State and society under the foundations of a territorial development contract

Análise de retorno de escala e tamanho do mercado no desempenho de equipes de vendas aplicando análise de envoltória de dados DEA: um estudo em empresa de Telecomunicações no Brasil

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate the performance of sales teams, based on a study of their coverage areas. Data was collected from the company contracted to distribute the products in the state of Ceará. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process.

Análise do mercado do abacaxi comercializado na CEAGESP - São Paulo

A disponibilidade de informações relativas à oferta, preços e sazonalidade do abacaxi é um fator de interesse tanto para produtores quanto para atacadistas, pois podem contribuir para melhor planejamento da época de colheita e comercialização. Dessa maneira, o presente trabalho buscou conhecer a sazonalidade do preço e da quantidade do abacaxi comercializado na CEAGESP - SP, no período de setembro de 2005 a março de 2006. Foram obtidos através de entrevistas aos atacadistas, dados referentes à origem de cada cultivar em estudo, o preço pago ao produtor, o preço de venda praticado pelos atacadistas e a quantidade de frutos recebida no dia. Com o objetivo de compreender o processo de comercialização das cultivares de abacaxi 'Smooth Cayenne' e 'Pérola', foram aplicados questionários aos vendedores de três empresas atacadistas. Através das informações obtidas, sugere-se aos produtores de abacaxi 'Smooth Cayenne' o escalonamento da produção no período de novembro a fevereiro, preferencialmente de maneira associativista. Os três atacadistas de abacaxi entrevistados vislumbram uma estabilidade na quantidade comercializada de abacaxi na CEAGESP, com previsão de crescimento para a cultivar 'Pérola' e redução para a cultivar 'Smooth Cayenne'. No período de 12 de setembro de 2005 a 20 de março de 2006, observou-se uma estabilidade de preços pagos ao produtor para ambas as cultivares, com elevação de preços entre os dias 23 de janeiro a 06 de março de 2006 para a cultivar 'Pérola' e entre os dias 06 de fevereiro a 06 de março de 2006 para a cultivar 'Smooth Cayenne'. Os atacadistas consideram a cultivar 'Smooth Cayenne' mais valorizada nos meses de novembro a janeiro e a cultivar 'Pérola' de março a junho e de novembro a dezembro. Pelo cenário de estabilização do mercado de abacaxi, torna-se fundamental a garantia de sabor monitorada pelas associações de produtores em parceria com o Centro de Qualidade em Horticultura (CQH - CEAGESP) e atacadistas, com destaque para a cultivar 'Smooth Cayenne'.

Análise da Conformidade e Caracterização da Matéria- Prima Empregada na Fabricação de Blocos Cerâmicos na Região Metropolitana de Salvador

The potential market of the metropolitan area of Salvador accounts for the estimated consumption of roughly 800 million horizontally perforated extruded clay bricks a year. The growing demand of consumers along with the competitiveness of the structural ceramic sector has driven forward a number of recent efforts and investments towards improving the quality of structural ceramics. In this scenario, the present study focused on sampling and evaluating the conformity of 8-hole horizontally perforated extruded clay bricks manufactured by different plants (A, B and C) in the metropolitan area of Salvador. In addition, representative clay and sandy-clay materials were collected from each plant and characterized by conventional physical, chemical and mineralogical techniques. Finally, experimental compositions designated as A, B and C, according to the source, were prepared by mixing different contents of the raw materials collected in the plants, fired at different temperatures and characterized. The results revealed a series of non conformities regarding ABNT guidelines. The characterization of raw materials revealed the presence of kaolinite and ilite in concentrations ranging from 64 to 90 wt.% along with free quartz (10 - 25%). The sandy-clay samples consisted basically of kaolinite. All raw materials depicted low contents of organics, amorphous constituents, alkaline oxides and feldspar. An analysis of the firing behavior of all different ceramic compositions revealed that the linear contraction of composition A was rather significant considering the temperature range evaluated, and it justifies the significant dimensional non conformity that was shown by bricks made with the ceramic A

A interface entre educação e mercado : uma análise crítica das mudanças socioculturais no contexto educacional

In the context of late modernity, the socio-cultural transformations established new social practices which corroborate discursive changes in dialectic movements, contributing to the order of the educational discourses to be more and more affected by typical market discourses and values which are covered by ideologies, hegemonic struggles and power relations. In this sense, this research study, which is based on the theoretical tenets of the Critical Discourse Analysis in its interdisciplinary branch (FAIRCLOUGH, 2006; ORMUNDO, 2010; PEDROSA, 2010; RAMALHO E RESENDE, 2011), aims at discussing how the sociocultural changes in the context of private education interact with the market proposal of neoliberal and economical policies. The research was methodologically based on the qualitative approach (CHIZZOTTI, 1991; BOGDAN e BIKLEN, 1994; MINAYO, 1994), especially on the principles of contemporary Applied Linguistics (SIGNORINI, 1998; MOITA-LOPES, 2006; MENEZES, SILVA, GOMES, 2009). Data were gathered from advertisements used in campaigns by private educational institutions and agencies in Natal/RN; the advertisements were collected in primary and secondary levels and in language courses from October to December, 2010. The data analysis indicate that education, in the context of globalization and late modernity, has become a market agency and that the new face of the educational discourse of private institutions is interwoven with a social representation of education as a site of struggle and hegemonic dispute. Therefore, the research leads us to infer that, as the educational public policies based on hegemonic economy and on ideological assumptions of international agents (Global Bank, FMI, etc.) have become widespread, education has become an arena of dispute and a powerful economic product to the market of cultural and commercial industry, thus emphasizing a society in which everything is economically based

A criança e o brinquedo-TV: análise sobre o discurso publicitário direcionado para a infância na Rede Globo de Televisão

Esta investigación es un análisis del contexto actual que rodea a la publicidad brasileña, más concretamente, la publicidad discurso televisivo dirigido a los niños en Brasil. Análisis de los documentos se basa en la revisión retórica (Leach, 2004) (SODRE, 2006) A partir de la primera supuesta inadecuación de algunos de sus contenidos al público para que se comunican. También investiga las posibilidades de regulación y la educación del consumidor y el papel de los medios de comunicación en la sociedad mediante la movilización exigiendo el cumplimiento y la mejora de la legislación vigente, evitando los posibles abusos y distorsiones de las secciones generales de la ley. Hemos llevado a cabo por separado se analiza en los niños y sus conceptualizaciones y la función social, abordando también el juguete y el acto de jugar hoy y su sede histórica en un intento de crear una fundación que apoya el análisis de la relación entre la infancia y la publicidad y el consumo, basado en obras de Roger Silverstone, Kapferer, Leontiev y Walter Benjamin. También se hicieron inferencias basadas en estudios de Pablo Del Río, sobre las posibles consecuencias psicológicas del consumo de medios por los niños, sin embargo, en arvorarmos llevar a cabo investigaciones en el estudio de la recepción. Se enfrentarán, tanto en acciones a favor de la aprobación de la Ley 5.921/2001 N º Suplente sugiere que la prohibición de la publicidad infantil en todo el país, los enfoques ampliamente "integrado" y por lo tanto, favorables a la continuidad de la actividad publicitaria en el país bajo la acción de la CONAR de autorregulación, lo que demuestra sin embargo, la viabilidad de ambas propuestas. Tambien relativa a el CONAR se llevó a cabo un estudio sobre su Consejo Asesor, dando a entender su composición y características. Por último, se estudian las posibilidades y el concepto de la educación para el consumo de los medios de comunicación, a partir de la utilización de los recursos de los propios medios de comunicación, como una propuesta para un cambio de paradigma en el mercado de la publicidad en Brasil. En conclusión, vemos que a partir del análisis de la publicidad comercial de los niños atendidos por la Red Globo de Televisión, en una muestra de 170 inserciones, todavía existen graves lagunas, pero que los desequilibrios se pueden resolver con medidas relativamente sencillas que incluyan campañas de educación y la exigencia de adecuación de los pocos grandes anunciantes que violan la ley. Afortunadamente, una nueva entrega de los anunciantes mostró la responsabilidad social en sus acciones

Ensino superior em Turismo: uma análise da relação dos cursos acadêmicos de Turismo da cidade do Natal-RN e o mercado de trabalho na percepção dos egressos dos anos de 2009 e 2010

The process of development of any area is closely linked to teaching and research, and in Tourism it is not different. Thus, in this area in which service is one of the factors intrinsically related to its success , it is observed the need for people with deep and critical training in the various aspects of this activity acting in this sector. However, we can see the existence of some differences between what is offered by the academy from what is required by the market. Therefore, the objective of this research is to verify the relationship between higher education in Tourism and labor market through the perception of the bachelor in this area, graduated in Natal-RN, since it is the tourismologist who makes the link between this two fields. To know the perception of these tourismologists, it was necessary to apply a questionnaire to those ones graduated in the years 2009 and 2010. In accordance with the aim of this study, this research was exploratory-descriptive. Related to the technical procedures, it was a documentary, literature and field research. To have it analyzed, some qualitative and quantitative techniques were applied according to our specific objectives and the types of data collected, such as: content analysis, factorial analysis to synthesize the information and identify the basic dimensions that represent the different variables studied, the standard deviation to verify the variation of the responses in some items and the correlation technique that allows the analysis of the relationship between two variables. In response to the objectives proposed here, we could finally conclude that: the syllabuses of these courses are too general and the graduates themselves consider them so. It was diagnosed that the graduates 1) are mostly female, 2) a very small part of them is working in the area that they are graduated in, and 3) not all of them receive satisfactory wages which contributes to having a negative view of their degree course. Moreover, the educational institution where they studied was not a decisive factor to get a job. It was still diagnosed that most part of them do not have positive perceptions when thinking about the future of their careers as bachelors in Tourism. Many of them, including, if it was possible to change something in their careers so far, they could have chosen another college degree. It was found that, although there is a negative perception about their professional future, almost half of them believe that the course met the needs of the market. However, those ones that are not working have a more positive point of view related to the applicability of higher education. On the other hand, the other ones who already worked in this area have a more negative perception about it and do not believe that the course meets the market's needs. In summary, this study allowed the understanding of the existence of some gaps that exist between higher education in Tourism and the market needs, professionally speaking, thus contributing to the spreading of ideas on that subject for teachers, researchers and the current and future students of the area.
