Simulação discreta aplicada à gestão de filas no varejo

Abstract: A concorrencia em mercados varejistas tem se tornado cada vez mais acirrada e com isso ha uma preocupacao crescente com a qualidade no atendimento como diferencial competitivo. Nessa perspectiva, a gestao de filas e um importante aliado e para tal, a utilizacao de tecnicas de simulacao de eventos discretos se faz extremamente util, apesar das poucas pesquisas desenvolvidas. Desta forma, o objetivo desse estudo foi analisar o dimensionamento de atendentes nos caixas de um supermercado a fim de verificar o impacto no atendimento devido a variacao dos resultados decorrente da alteracao no numero de atendentes. Foi possivel constatar que o metodo de simulacao a eventos discretos combinado com a simulacao computacional permite analisar cenarios diversos apoiando as tomadas de decisao para o dimensionamento adequado do numero de atendentes nos caixas, a viabilidade e o ponto de ruptura entre o fluxo continuo de clientes e a geracao de filas.

Morphology of juvenile phase of Achelous spinimanus (Latreille, 1819) (Crustacea, Decapoda, Portunidae) reared in laboratory

Abstract: The swimming crab Achelous spinimanus is an important fishery component of several countries in the Western Atlantic; therefore, knowledge of the different phases of its life cycle is essential for good management of this resource. The juvenile development of A. spinimanus was investigated in the laboratory, from megalopae captured in neuston samples at Ubatuba, Sao Paulo, Brazil (23°26′S 46°09′W), during the summer months of 2005–2007. Rearing was performed in a constant temperature (25 ± 1°C), filtered seawater from the collection location (35 psu) and natural photoperiod. We obtained nine stages of the juvenile phase. All the morphological characters that allow the recognition of the first juvenile stage were drawn and described, as well as the main alterations that occur in the following stages. The sexual differentiation based on the number of pleopods becomes apparent from the third stage on. Some important characters in the identification of the species at the juvenile phase are the number of segments on the exopod of antennule, on the antennal flagellum and on the palp of mandible, beyond the absence of pleopods (even rudimentary) in the first stage.

Decolonialidade e ensino de línguas: perspectivas e desafios para a construção do conhecimento corporificado no cenário político atual

Abstract: Este trabalho tem como objetivo refletir sobre as recentes politicas publicas e educacionais brasileiras e a tentativa de naturalizacao da ideologia dos grupos dominantes, em detrimento a legitimacao da pluralidade epistemologica de grupos marginalizados e/ou contrarios a tal pensamento uniformizador. A partir das teorias de decolonialidade (CASTRO-GOMEZ; GROSFOGUEL, 2007; LANDER, 2005; MIGNOLO, 2009; MORENO, 2005; SOUSA SANTOS, 2010), discuto as relacoes de submissao, subordinacao e exclusao promovidas pelas politicas educacionais recentes. Em seguida, busco problematizar o papel da educacao para o desenvolvimento da criticidade e da construcao do conhecimento corporificado, isto e, construido a partir de corpos atravessados por diferentes identidades culturais, sociais, linguisticas, de raca e de genero, e concluo ressaltando a importância do ensino da lingua inglesa como uma tarefa politica que desenvolva o questionamento, o pensamento critico e o respeito a diversidade epistemologica.

Comparative positioning between Brazilian subsidiaries and European matrices on Electromobility and carsharing technologies

Abstract: Resume The challenges related to mobility have generated discussions among all sectors of society and have a decisive influence on the decline of people's quality of life. At the heart of this discussion is the difficulty in accessing the services and opportunities in the cities due to the barriers imposed by current urban mobility standards. Based on the understanding that the use of the current model is a complex issue, since it is rooted in the culture of some societies, the research uses a qualitative approach through a multicases study to evaluate how the Brazilian automotive industry positioning from a transition process in which the urban mobility has been facing, in which sustainability is also a requirement of society. And more than that, it searches to evaluate whether this industry actually participates in this transition or positions itself in a defensive way by analyzing two areas of action: electromobility and carsharing. The Brazilian case, one of the countries with the greatest diversity of energy matrices in a context of large urban areas, presents a greater availability of different propulsion technologies, a fact that further increases the uncertainties for the automotive industry. Until a dominant system is set up, it is possible that different regimes can coexist. Hybrid technology involving ethanol and electromobility, which manifests itself in public transport, configures a unique case for the national reality.
