Competição espacial no mercado de revenda da gasolina: uma análise nas principais cidades do Rio Grande do Norte

This study aims to analyze the relationship between average price with the concentration in the markets (municipalities) in the state of Rio Grande do Norte, is using a little tool applied to the Brazilian market is the spatial econometric model. A data base contains all the stations of the major cities in the state of Rio Grande do Norte and includes 142 observations on stations was used. Theoretical models predict the relationship between the number of competitors in a market and the average price; these theoretical models include: the monopolistic competition of Perloff and Salop (1985), and the search-theoretic, of Carlson and McAfee (1983) and Varian (1980). The empirical results showed that a higher density within a geographic area is associated with a lower average price, thus converging with the monopolistic competition model and with the search-theoretic of Carlson and McAfee (1983). The parameters varied little with the inclusion / exclusion of control variables, showing the robustness of them.

Análise das LER/DORT notificadas no Rio Grande do Norte de 2010 a 2014

The increasing prevalence of Repetitive Strain Injury / Work-Related Musculoskeletal Disorders (RSI / MSDs) has been explained by changes in the work that has been characterized by setting goals and productivity. This fact does not take into account the psycho-physiological characteristics of workers who become ill as a result of professional activities engaged in and also the adverse conditions in which his work was done. This study aimed to analyze the RSI / MSDs reported in the state of Rio Grande do Norte, Brazil, 2010-2014 compared to the profile of the population, epidemiological aspects and features of these diseases. It is a descriptive epidemiological cross-sectional study using secondary data obtained in the Notifiable Diseases Information System (SINAN) in May 2015 was used as the area covered by the Rio Grande do Norte. Data were collected regarding the grievances of work-related RSI / MSDs, assigned by the Worker's Health Reference Center (CEREST) of the State Health Department. Data were processed with the help of Microsoft Excel® 2013 and presented in tables in absolute frequency (n) and relative frequency (%). The results showed a total of 403 notifications of RSI / MSDs, where the vast majority 72% (290) was recorded in Natal. Regarding the profile of notified employees, 88.59% (357) have aged between 25 and 54 years, 62.78% (253) were female, and in relation to education, 31.51% (127) had high school complete. The most affected occupations were seamstresses (the clothing industry) with 24.97% (97), followed by masons, construction with 3.23% (13) and cashiers with 2.99% (12). About the work situation, 75.93% (306) had a formal contract, however, were sent to Communications Occupational accidents (CAT) only 67% (270) of the cases. Regarding the signs and symptoms, pain and limitation of movement were the most mentioned respectively with 98.01% (395) and 95.04% (383) of notifications. Notifications, 94.29% (380) showed exposure to repetitive movements in their workplace. The most frequent specific diagnoses were synovitis and tenosynovitis (CID F 65), with 30.02% (121) of notifications, followed by back pain (CID F 54) to 19.35% (78) and shoulder injuries (ICD M 75) with 15.88% (64). They were away from work 81.64% (329) of workers reported with RSI / MSDs. Evolution more prevalent among cases was temporary disability with 75.68% (305). It was concluded that the SINAN is a database of potential to characterize the profile of RSI / MSDs, requiring, however, an improvement in the coverage of records and data quality. In addition, this study reflects the need to implement protection strategies to workers by companies, signaling promotion, prevention and rehabilitation aimed at reducing these injuries and the improvement of occupational health indicators in Rio Grande do Norte.

O Supremo Tribunal Federal como agente tecnocrático no exercício da jurisdição constitucional na solução de casos complexos : análise das ações diretas de inconstitucionalidade nº 3937/SP e nº 3357/RS

Many changes have taken place in contemporary society causing impacts in its different sectors, making it much more complex and insecure than in past times. The alteration on the decision-making system of the Brazilian society is among the main changes today. The post-modern context contributed to the occurrence of the transfer of state power of the Legislative and Executive Powers to the Judiciary Power, specifically to the Federal Court of Justice, leading to an expansion on the actuation range of this institution mainly through the exercise of the constitutional jurisdiction. This has caused a crisis of legitimacy in society once the Court will now decide the political and social fundamental issues. In this scenario, the Direct Action of Unconstitutionality n° 3937/SP and n° 3357/RS are highlighted and both are being tried by the Supreme Court. Such emphasis is given, since it is a matter of high complexity and social repercussion that will be decided by a legal institution and not a political one. Thus, this work aims to analyze the role of the Supreme Court in the context of contemporary society on the trial of complex and controversial cases, particularly on the trial of Direct Action of Unconstitutionality n° 3937/SP and n° 3357/RS. This study has noticed that due to the post-modern context the majority of the Supreme Court Ministers tend to base their votes in constitutional principles and no longer limit themselves to a formal review of the constitutionality of laws, which indicates a substantialist approach. Moreover, it can be noticed the deliberative potential of the Court as well as the influence of the post-modern features, such as risk, uncertainty and insecurity on the elaboration of the Minister‟s votes. Therefore, sometimes, such as the case in study, the Supreme Court has acted as a technocratic agent in Brazilian society once fundamental political and social decisions for society especially when it comes to complex and controversial cases are being taken by the Supreme Court, which is composed by “Law technicians” and such decisions are mainly based in technical data and scientific studies. For the accomplishment of this work, it has been adopted the inductive approach and monographic procedure method and the bibliographical and documentary research technique.

Bola na rede: uma análise das estratégias comunicacionais de empresas esportivas no ambiente digital conectado

O uso das mídias sociais digitais como meio de divulgação de produtos, serviços e conteúdos organizacionais tem crescido nas últimas décadas e ganhou especial atenção nos planejamentos de comunicação organizacional e nos estudos acadêmicos sobre o tema. Nesse sentido, o segmento de empresas esportivas atua com destaque, despertando o interesse e a empatia do consumidor. Por meio de análise bibliográfica e estudo empírico, esta pesquisa teve como objetivo investigar as ações de comunicação mercadológica do segmento esportivo no ambiente digital conectado, através de um estudo de caso múltiplo das empresas Nike e Adidas. Para a obtenção dos dados, foram realizadas entrevistas em profundidade com profissionais do mercado e aplicado um protocolo de investigação de redes sociais digitais nos perfis das duas empresas. Após a coleta dos dados, estes foram analisados à luz das teorias estudadas nos capítulos iniciais (que abordaram temas como comunicação organizacional, comunicação digital, esporte e comunicação esportiva), e foi possível concluir, entre outros pontos, que, no universo do segmento esportivo, a comunicação digital conectada não prioriza o diálogo com seus públicos de interesse, sendo essencialmente baseada na divulgação unilateral de conteúdos, nem tampouco explora a potencialidade de cada uma das plataformas digitais disponíveis, replicando conteúdos em diferentes ambientes. Ficou evidente, também, o uso dos elementos constituintes do universo esportivo como argumentos estratégicos de comunicação das empresas, decorrente de sua capacidade de estreitar os laços relacionais com os públicos de interesse, por meio de seus apelos simbólicos de fácil identificação social.

COMUNICAÇÃO E MARKETING NA EDUCAÇÃO SUPERIOR: uma análise dos conteúdos comunicacionais online de instituições de ensino privadas

O presente contexto mercadológico da educação superior, onde a concorrência é cada vez mais acirrada, tem levado as instituições de ensino a estabelecer um processo de gestão de comunicação e marketing mais estratégico e competitivo, buscando alcançar uma posição diferenciada em relação à concorrência, a fim de conquistar seus públicos de interesse. Este trabalho contemplou a aplicação dos objetivos de comunicação no mercado de ensino superior, analisando as formas pelas quais as instituições vêm estabelecendo os processos comunicacionais com seus públicos-alvo, estando direcionado para as Universidades privadas brasileiras. A pesquisa se apóia em: revisão bibliográfica, entrevistas em profundidade com gestores de comunicação e marketing do setor pesquisado e análise de conteúdo de peças de comunicação em mídia online. Inicialmente foi elaborado um relato acerca do contexto atual do mercado de ensino superior no Brasil: sua evolução e caracterização. Em seguida, definiu-se marketing aplicado ao segmento de educação superior: conceitos e o papel designado a ele. Posteriormente relacionou-se comunicação mercadológica com o serviço de educação superior e sua aplicabilidade neste setor. Depois, foram realizadas entrevistas em profundidade - semiestruturadas, com gestores de comunicação e marketing de duas instituições, localizadas na cidade de São Paulo (Insper e Universidade São Judas Tadeu) com posicionamentos antagônicos e classificações distintas quanto à sua imagem para o mercado -, com a finalidade de conhecer suas visões e opiniões sobre o mercado e as ações de comunicação de marketing que vêm adotando. Finalmente, foi elaborada análise de contéudo, comparando anúncios (peças publicitárias) em mídia online das duas IES estudadas. Todos os procedimentos da análise de contéudo foram estabelecidos e categorizados com base nos objetivos de comunicação definidos por Yanaze (2011).

Análise comparativa e teste empírico da validade dos modelos CAPM tradicional e condicional: o caso das ações da Petrobrás

ALVES, Janaína da Silva. Análise comparativa e teste empírico da validade dos modelos CAPM tradicional e condicional: o caso das ações da Petrobrás. Revista Ciências Administrativas, Fotaleza, v. 13, n. 1, p.147-157, ago. 2007.

Análise da sobre-reação e sub-reação nos ativos de primeira e segunda linha do mercado acionário brasileiro

The Behavioral Finance develop as it is perceived anomalies in these markets efficient. This fields of study can be grouped into three major groups: heuristic bias, tying the shape and inefficient markets. The present study focuses on issues concerning the heuristics of representativeness and anchoring. This study aimed to identify the then under-reaction and over-reaction, as well as the existence of symmetry in the active first and second line of the Brazilian stock market. For this, it will be use the Fuzzy Logic and the indicators that classify groups studied from the Discriminant Analysis. The highest present, indicator in the period studied, was the Liabilities / Equity, demonstrating the importance of the moment to discriminate the assets to be considered "winners" and "losers." Note that in the MLCX biases over-reaction is concentrated in the period of financial crisis, and in the remaining periods of statistically significant biases, are obtained by sub-reactions. The latter would be in times of moderate levels of uncertainty. In the Small Caps the behavioral responses in 2005 and 2007 occur in reverse to those observed in the Mid-Large Cap. Now in times of crisis would have a marked conservatism while near the end of trading on the Bovespa speaker, accompanied by an increase of negotiations, there is an overreaction by investors. The other heuristics in SMLL occurred at the end of the period studied, this being a under-reaction and the other a over-reaction and the second occurring in a period of financial-economic more positive than the first. As regards the under / over-reactivity in both types, there is detected a predominance of either, which probably be different in the context in MLCX without crisis. For the period in which such phenomena occur in a statistically significant to note that, in most cases, such phenomena occur during the periods for MLCX while in SMLL not only biases are less present as there is no concentration of these at any time . Given the above, it is believed that while detecting the presence of bias behavior at certain times, these do not tend to appear to a specific type or heuristics and while there were some indications of a seasonal pattern in Mid- Large Caps, the same behavior does not seem to be repeated in Small Caps. The tests would then suggest that momentary failures in the Efficient Market Hypothesis when tested in semistrong form as stated by Behavioral Finance. This result confirms the theory by stating that not only rationality, but also human irrationality, is limited because it would act rationally in many circumstances

Análise experimental do efeito da diversificação em carteiras de ações: a relação entre risco e quantidade de ativos sob a ótica da estratégia ingênua

The objective is to analyze the relationship between risk and number of stocks of a portfolio for an individual investor when stocks are chosen by "naive strategy". For this, we carried out an experiment in which individuals select actions to reproduce this relationship. 126 participants were informed that the risk of first choice would be an asset average of all standard deviations of the portfolios consist of a single asset, and the same procedure should be used for portfolios composed of two, three and so on, up to 30 actions . They selected the assets they want in their portfolios without the support of a financial analysis. For comparison we also tested a hypothetical simulation of 126 investors who selected shares the same universe, through a random number generator. Thus, each real participant is compensated for random hypothetical investor facing the same opportunity. Patterns were observed in the portfolios of individual participants, characterizing the curves for the components of the samples. Because these groupings are somewhat arbitrary, it was used a more objective measure of behavior: a simple linear regression for each participant, in order to predict the variance of the portfolio depending on the number of assets. In addition, we conducted a pooled regression on all observations by analyzing cross-section. The result of pattern occurs on average but not for most individuals, many of which effectively "de-diversify" when adding seemingly random bonds. Furthermore, the results are slightly worse using a random number generator. This finding challenges the belief that only a small number of titles is necessary for diversification and shows that there is only applicable to a large sample. The implications are important since many individual investors holding few stocks in their portfolios

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

PROJETOS PROBLEMÁTICOS: Proposta de Framework para diagnóstico prematuro e direcionamento de ações preventivas

Ao longo dos últimos anos vários estudos de benchmarking em gerenciamento de projetos têm demonstrado a baixa evolução nos indicadores de desempenho de gerenciamento de projetos, sinalizando que as empresas pouco têm aprendido com as experiências negativas.Projetos com algum nível de deterioração em seus indicadores, caracterizados pela literatura e pelo mercado como complexos, problemáticos, em crise ou fracassados são frequentes e não tem sido percebido iniciativas preventivas a fim de impedir antecipadamente a deterioração dos indicadores destes projetos. A partir do estudo da bibliografia técnica e científica disponível, este trabalho buscou responder ao seguinte questionamento: É possível desenvolver um Framework, voltado para o diagnóstico prematuro e direcionamento de ações preventivas de projetos problemáticos, a partir da experiência de pessoas que vêm atuando nestes projetos e da literatura e pesquisas disponíveis? A partir da definição de um recorte que defina a expressão “projetos problemáticos” e da análise de referenciais bibliográficos, buscou-se reconhecer, via questionário de pesquisa quantitativa, com amostra não probabilística por conveniência, os sintomas que são percebidos com maior frequência nesses projetos. O questionário foi aplicado no segundo semestre de 2015, com foco nos respondentes da região Sudeste do Brasil, tendo sido obtidas 265 respostas válidas. A partir da análise dos dados obtidos, concluiu-se que os sintomas mais frequentes reconhecidos nos projetos problemáticos vivenciados por profissionais atuantes em projetos na região Sudeste do Brasil estão relacionados às hipóteses de que “O planejamento do projeto e o gerenciamento de riscos não ocorreram conforme as boas práticas de gerenciamento de projetos”, e de que “Não havia uma iniciativa efetiva de gestão do conhecimento em todo o ciclo de vida do projeto”. Utilizando como norte os resultados de maior expressividade obtidos via questionário de pesquisa, propôs-se um Framework genérico voltado para o diagnóstico prematuro de projetos problemáticos, e eventual direcionamento de ações preventivas e corretivas, nos casos em que já haja deterioração efetiva do desempenho desses projetos.

Análise de cursos e treinamentos in company como intervenções educacionais estratégicas

O cenário empresarial brasileiro passa por dificuldades de caráter financeiro e político, conduzindo a ideia de que as organizações demandem ainda mais empenho, perseverança no negócio e dedicação para que os resultados obtidos sejam cada vez melhores. Uma estratégia que tem ganhado força no mercado é a de treinamentos e cursos in company, que ocorrem quando uma empresa promove capacitação e desenvolvimento profissional a partir de seus próprios colaboradores especialistas ou da contratação de empresas especializadas para fornecer conhecimento sobre assuntos específicos pontuais. Comumente, estas iniciativas têm curta duração e podem ter diversos objetivos, desde projetos momentâneos até a capacitação a longo prazo de competências individuais dos colaboradores que compõem as organizações. No contexto da Educação, a medida de estudo - a metodologia in company – se relaciona com o caráter pedagógico das organizações, que entendem este tipo de curso e treinamento como uma possibilidade educacional para seus colaboradores. O que se percebe é que a necessidade do mercado é de diferenciação, inovação e criatividade. Várias são as características do indivíduo que se relacionam com a criatividade (Wood Jr, 2002) logo, as empresas que estão se destacando no cenário atual são as que ousam mais, investem não só em ações e projetos, mas também em iniciativas criadas por e para seus próprios colaboradores, que se tornam os grandes co-autores do sucesso das organizações. O presente estudo teve como objetivo perceber os impactos e benefícios da aplicação destes cursos e treinamentos modelo in company não só para a organização que o implementa, mas também para cada colaborador individualmente. Para alcançar este objetivo da forma mais completa possível, desenvolveu-se uma pesquisa qualitativa aplicada a uma empresa fornecedora de cursos in company e outra formato focus group aplicada aos colaboradores que vivenciaram esta experiência, com recurso a consulta de legislação, observações livres, entrevistas presenciais a oito colaboradores da organização Som Livre, com idades entre 25 e 35 anos e, desta forma, responder às questões que estimularam o início desta investigação.
