QUANTIFICAÇÃO E COORDENAÇÃO DE SISTEMAS AGROINDUSTRIAIS: O CASO DO TRIGO NO BRASIL

The present article presents an overview of the Agribusiness System of wheat in Brazil. Departing from a methodology developed for mapping and quantifying value chains, the structure of the respective chain is presented, with the main sectors identified and quantified (revenue of the sector with the wheat chain sales in Brazil in 2002). Also, the main coordination problems were identified in the system, as well as the development of a work agenda containing a list of collective actions that should be implemented by the private initiative, in order to minimize the existing problems. It was suggested to the several members of the wheat chain the establishment of an organization, which will integrate the entire system, named Trigo-Brasil (Wheat-Brazil, for implementing the proposed collective actions.agribusiness system, distribution channels, wheat., Agribusiness, Crop Production/Industries,

CENÁRIO DE PRÁTICAS EMPRESARIAIS EM INTELIGÊNCIA COMPETITIVA NA INDÚSTRIA DE TELECOMUNICAÇÕES. UM ESTUDO SOBRE A PRÁTICA EM EMPRESAS NO BRASIL SOB O FRAMEWORK WRIGHT-PICKTON

Este trabalho aplica o modelo Wright-Pickton em inteligência competitiva (IC) na realidade de negócios de empresas brasileiras da indústria de telecomunicac¸ões. O objetivo central foi descrever o estágio de uso de conceitos e ferramentas de IC conforme avaliac¸ão de líderes dessas áreas em empresas do setor. A coleta de informac¸ões deu-se por meio de entrevistas em profundidade com os executivos que lideram áreas ou func¸ões similares à área de IC em oito empresas muito representativas desse setor que atuam em diferentes áreas da cadeia de valor. As informac¸ões obtidas foram analisadas e categorizadas seguindo diretrizes do método de análise de conteúdo à luz do modelo de Wright-Pickton. Como resultado final, percebeu-se que os aspectos coleta de dados e uso dos outputs de IC são os que estão mais distantes do considerado ideal, pontos que devem ser aperfeic¸oados para tornar a prática mais próxima possível da estratégia da companhia. Ainda, o trabalho traz sugestões de aprimoramento do modelo conceitual usado provenientes da aplicac¸ão na realidade brasileira, bem como da investigac¸ão sistematizada da literatura relacionada ao tema de IC, que também é apresentada neste trabalho

MARKETING DA CARNE BOVINA COM VISÃO DE REDES de EMPRESAS (“NETWORKSâ€)

The beef business is composed of several networks, called here the agri-food networks. These are defined as a group of suppliers and distributors of an analyzed firm (in an individual case), or of the alliance being analyzed (in case of firms that manage a common brand). In this article a scenario analysis is done based on a review of the recent data and trends on Brazilian and global beef market, and many impacts to the beef business are identified. The main contribution from this scenario analysis is the observation of the emergence of 4 main networks that will rest stronger in global beef market in 2010. These networks will operate and coexist in 4 different market segments, with different needs.cattle breeding, agri-food networks, red beef, Marketing, Livestock Production/Industries,

Measurement of the Bottom-Strange Meson Mixing Phase in the Full CDF Data Set

We report a measurement of the bottom-strange meson mixing phase \beta_s using the time evolution of B0_s -> J/\psi (->\mu+\mu-) \phi (-> K+ K-) decays in which the quark-flavor content of the bottom-strange meson is identified at production. This measurement uses the full data set of proton-antiproton collisions at sqrt(s)= 1.96 TeV collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.6 fb-1 of integrated luminosity. We report confidence regions in the two-dimensional space of \beta_s and the B0_s decay-width difference \Delta\Gamma_s, and measure \beta_s in [-\pi/2, -1.51] U [-0.06, 0.30] U [1.26, \pi/2] at the 68% confidence level, in agreement with the standard model expectation. Assuming the standard model value of \beta_s, we also determine \Delta\Gamma_s = 0.068 +- 0.026 (stat) +- 0.009 (syst) ps-1 and the mean B0_s lifetime, \tau_s = 1.528 +- 0.019 (stat) +- 0.009 (syst) ps, which are consistent and competitive with determinations by other experiments.Comment: 8 pages, 2 figures, Phys.

Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations

Context. A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of which yielded a central flash detection. Aims. We aimed at constraining Triton's atmospheric structure and the seasonal variations of its atmospheric pressure since the Voyager 2 epoch (1989). We also derived the shape of the lower atmosphere from central flash analysis. Methods. We used Abel inversions and direct ray-tracing code to provide the density, pressure, and temperature profiles in the altitude range similar to 8 km to similar to 190 km, corresponding to pressure levels from 9 mu bar down to a few nanobars. Results. (i) A pressure of 1.18 +/- 0.03 mu bar is found at a reference radius of 1400 km (47 km altitude). (ii) A new analysis of the Voyager 2 radio science occultation shows that this is consistent with an extrapolation of pressure down to the surface pressure obtained in 1989. (iii) A survey of occultations obtained between 1989 and 2017 suggests that an enhancement in surface pressure as reported during the 1990s might be real, but debatable, due to very few high S/N light curves and data accessible for reanalysis. The volatile transport model analysed supports a moderate increase in surface pressure, with a maximum value around 2005-2015 no higher than 23 mu bar. The pressures observed in 1995-1997 and 2017 appear mutually inconsistent with the volatile transport model presented here. (iv) The central flash structure does not show evidence of an atmospheric distortion. We find an upper limit of 0.0011 for the apparent oblateness of the atmosphere near the 8 km altitude.J.M.O. acknowledges financial support from the Portuguese Foundation for Science and Technology (FCT) and the European Social Fund (ESF) through the PhD grant SFRH/BD/131700/2017.

ANÁLISE DA COMPETITIVIDADE DO APL DE PISCICULTURA NO LAGO DE TRÊS MARIAS

Objetivou-se, neste artigo, analisar a competitividade e as potencialidades da piscicultura no Lago de Três Marias em Minas Gerais, dado que é latente o desenvolvimento dessa atividade como alternativa econômica para a região. São utilizadas a visão de APL (Arranjo Produtivo Local), com contribuições da Nova Economia Institucional e de coordenação em sistemas agroindustriais, como modelos de análise. Como método para coleta de dados, foi realizado um levantamento de dados in loco por meio de entrevistas e da organização de um workshop com agentes participantes do APL. Foi possível concluir que, a despeito das grandes vantagens em termos de recursos naturais e apoio governamental, grande parte dos desafios para aumentar a competitividade da atividade está relacionada à consolidação das instituições e à melhoria da coordenação vertical e horizontal entre os agentes participantes. Uma vez que essas ações e definições estejam implementadas, é razoável supor que recursos e competências locais existentes serão mais bem aproveitados, gerando benefícios econômicos e sociais relevantes para uma região ainda pouco desenvolvida no Brasil, mas com potencial notável

REDES, CAPITAL SOCIAL E MARKETING COMO ELEMENTOS FUNDAMENTAIS PARA A AGRICULTURA FAMILIAR: UMA EXPERIENCIA NO PROJETO PUBLICO DE IRRIGACAO JAIBA

This study discusses an experience of a group of small lemon growers in a public irrigation project called Jaíba, partnering with a private company called Itacitrus, besides Codevasf (Development Company of the Valleys of San Francisco and Parnaiba). Because of the known difficulties of turning small properties into profitable units inside public irrigation projects in Brazil, the study aims to understand which were the elements that allowed the sustainable growth of the growers’ association. This paper identifies and analyses investments of each party involved in the partnership and their shared responsibilities. The method used is the in-depth case study, along with documental research and observation that allowed bringing up multiple and different variables over the phenomenon. The concept of networks is used along with social capital and marketing. The conclusions indicate that small family producers should acquire or develop product quality management techniques as well as trade competences. Secondly, trading companies should be able to develop long term partnerships with producers and governmental entities must evaluate whether critical competences are present as a way to drive public investments

EFICIÊNCIA DE REPRESENTAÇÃO DAS ASSOCIAÇÕES DE PRODUTORES DE CANA-DE-AÇÚCAR NO BRASIL

The associative model for sugarcane growers is based on their association per region. In the Center-South Region of Brazil, for example, there are 31 associations with about 18 thousand growers, and locally represented by the Sugarcane Growers Organization of the Center-South Region of Brazil (ORPLANA). However, recent sector changes, especially in terms of deregulation, crisis and consolidation, have led some associations to the weakening. On the other side, some associations have grown in the last years. This variability shows the need for studying the existing differences among associations in terms of the role they perform, as well as an investigation of which organizational profile ismore related to their growth and development; configuring a clear representation efficiency. This research was performed within the view of transaction cost economics, with contribution of collective action theory. Questionnaires were applied to 23 managers or presidents of associations. In addition, the statistical grouping based method was used. According to results, three distinct groups of association were identified, which were named as “Techniques”, “Politics”, and “Spokespeople”. The first group was found to be more efficient and prosperous in growth than others. Besides, it has striking features on its profile, such as a diverse scope of activities, high size, developed structure, involvement with cooperatives, strong performance in services, and great number of factories
