    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Produção, Florianópolis, 2013Organizações onde a inovação, a agilidade e a flexibilidade, se constituem em fatores competitivos relevantes, a Gestão do Portfólio de Produtos (GPP) impacta diretamente em seus objetivos estratégicos. Em relação ao ambiente externo, sua atuação é essencial para que as necessidades dos consumidores sejam melhor atendidas. No ambiente interno, a GPP auxilia na simplificação dos processos. Neste contexto é desenvolvida a presente pesquisa onde o objetivo é construir um modelo de apoio à decisão, segundo os valores e preferências dos Gerentes de Marketing e de Tecnologia de uma companhia de eletrodomésticos, que evidencie, organize e mensure os aspectos críticos para o sucesso da GPP e permita seu monitoramento e contínuo aperfeiçoamento. Para alcançar tal objetivo, a pesquisa iniciou com um processo de seleção e análise de artigos científicos. Seu propósito foi reunir trabalhos relevantes já publicados sobre o tema "Avaliação de Desempenho da Gestão do Portfólio de Produtos", identificando seus pontos fortes e fraquezas. Com isso, obteve-se, a pergunta e objetivo de pesquisa, direcionando o trabalho no sentido de fazer uso dos pontos fortes e suprir as fraquezas explicitadas. A seguir, o estudo fez uso de uma abordagem quali-quantitativa aplicada em forma exploratória a um Estudo de Caso. O instrumento de intervenção utilizado foi à metodologia MCDA-C, por permitir a expansão do conhecimento nos decisores acerca das consequências de suas decisões nos aspectos que eles julgam críticos para o sucesso da companhia. Entre os resultados do estudo estão a identificação, organização e mensuração ordinal e cardinal de 44 critérios. Além disso, foi realizada sua integração, a partir da identificação das taxas de compensação; o diagnóstico da situação atual; e, a elaboração de ações de aperfeiçoamento. Abstract: Organizations where innovation, agility and flexibility, constitute relevant competitive factors, the Portfolio Management Products (PPM) impacts directly on its strategic objectives. In relation to the external environment, its performance is critical to consumers' needs are best met. In the internal environment, PPM helps in streamlining processes. In this context the present research is developed where the goal is to build a model of decision support, based on the values and preferences of Marketing and Technology Managers of an appliance company, giving evidence, organize and measure critical aspects to the success of PPM and allow its monitoring and continuous improvement. To achieve this objective, the research began with a process of selection and analysis of scientific papers. His purpose was to gather relevant work already published on the topic "Performance Evaluation of Portfolio Management Product", identifying their strengths and weaknesses. Thus, we obtained the question and research objective, directing the work to make use of the strengths and overcome the weaknesses explained. Next, the study used a qualitative and quantitative approach applied in an exploratory way to a Case Study. The intervention instrument used was the MCDA-C methodology, allow for the expansion of knowledge in decision makers about the consequences of their decisions in ways that they deem critical to the success of the company. Among the study's findings are the identification, organization and measurement ordinal and cardinal criteria of 44. Additionally, its integration was performed from the identification rates of compensation; diagnosis of the current situation, and the elaboration of improvement

    Organizações onde a inovação, a agilidade e flexibilidade, se constituem em fatores competitivos relevantes, a gestão de portfólio de produtos (GPP) impacta diretamente em seus objetivos estratégicos. Em relação ao meio externo, sua atuação é essencial para que as necessidades dos consumidores sejam melhor atendidas. Ao mesmo tempo, no que tange ao meio interno, a GPP deve ter participação na simplificação dos processo, disponibilizando uma flexibilidade adequada para atender às necessidades dos clientes. Neste ambiente é desenvolvida a presente pesquisa onde o objetivo é construir um modelo de apoio à decisão que evidencie as consequências das decisões tomadas. Por se tratar de um contexto complexo, onde o decisor necessita que seu entendimento seja expandido, será utilizada a metodologia MCDA-C, auxiliando o decisor a construir o modelo personalizado a seus valores e preferências. Este artigo ilustra o processo para uma empresa de eletrodomésticos, focando na área de Marketing

    O presente estudo objetivou identificar as diversas espécies vegetais utilizadas em rituais de candomblé e com fins medicinais indicadas por pais e mães-de-santo em terreiros nos municípios de Ilhéus e Itabuna, BA, fornecendo informações acerca da procedência das espécies (cultivo, feiras livres e extrativismo em Mata Atlântica e/ou áreas ruderais). Entrevistas semi-estruturadas com 15 pais e mães-de-santo e coleta de material botânico foram realizadas em dez terreiros de candomblé. Foram inventariadas 78 espécies pertencentes a 44 famílias, sendo Asteraceae (nove espécies), Lamiaceae (sete espécies), Fabaceae e Myrtaceae (quatro espécies) as de maior representatividade. A maioria dessas espécies é utilizada para fins medicinais (53,21%), seguidas daquelas utilizadas para fins litúrgicos (30,27%) e ornamentais (16,51%). Observou-se que o cultivo (39,89%) sobressaiu-se sobre a obtenção em feiras livres (25,53%) e/ou extrativismo (34,57%). Constatou-se que os conhecimentos místicos, culturais e farmacobotânicos dos participantes mais efetivos e tradicionais do candomblé são imensuráveis. Estudos de etnobotânica nesta área demonstram grande importância para que estas informações que remontam séculos e fazem parte da história e cultura de nosso povo não sejam perdidas

    2 nd Brazilian Consensus on Chagas Disease, 2015

    Full text link
    Abstract Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research

    Proton–proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb−1 , are analysed to search for the charmless B0→ρ0ρ0 decay. More than 600 B0→(π+π−)(π+π−) signal decays are selected and used to perform an amplitude analysis, under the assumption of no CP violation in the decay, from which the B0→ρ0ρ0 decay is observed for the first time with 7.1 standard deviations significance. The fraction of B0→ρ0ρ0 decays yielding a longitudinally polarised final state is measured to be fL=0.745−0.058+0.048(stat)±0.034(syst) . The B0→ρ0ρ0 branching fraction, using the B0→ϕK⁎(892)0 decay as reference, is also reported as B(B0→ρ0ρ0)=(0.94±0.17(stat)±0.09(syst)±0.06(BF))×10−6
