Some forgotten equilibria of the Bertrand duopoly!?
No full textThis note analyzes the Bertrand duopoly with constant but asymmetric marginal costs on a market with homogenous products. It is shown that there exist some equilibria that are ignored in the literature on IO. In addition, in this setting (perfectly or nearly perfectly) competitive equilibria exist.
Use of Salmon Cardiac Primary Cultures (SCPCs) of different genotypes for comparative kinetics of mx expression, viral load and ultrastructure pathology, after infection with Salmon Pancreas Disease Virus (SPDV)
No full textIn vitro fish based models have been extensively applied in human biomedical research but, paradoxically, less frequently in the research of fish health issues. Farmed Atlantic salmon can suffer from several viral conditions affecting the heart. Therefore, species-specific, cardiac in vitro models may represent a useful tool to help further understanding and management of these diseases. The mechanisms underlying genotype based resistance are complex and usually rely on a combined effect of elements from both the innate and adaptive immune response, which are further complicated by external environmental factors. Here we propose that Salmon Cardiac Primary Cultures (SCPCs) are a useful tool to investigate these mechanisms as the basis for genotypic differences between Atlantic salmon families in susceptibility to cardiotropic viral disease. Using SCPCs produced from two different commercially available Atlantic salmon embryonated ova (Atlantic Ova IPN sensitive" (S) and "Atlantic QTL-innOva(®) IPN/PD" (R)), the influence of host genotype on the viral load and mx expression following Salmon Pancreas Disease Virus infection was assessed over a 15 day period. Both R and S SCPCs groups were successfully infected. A measurable difference between groups of viral nsP1 and host antiviral mx gene expression was observed (i.e. a later, but larger onset of mx expression in the R group). Mx expression peaks were followed by a decrease in viral nsP1 in both groups. Additionally, ultrastructural examination of infected SCPCs allowed the description of degenerative changes at the individual cell level. The SCPC model presents some advantages, over current fish cell culture monolayers and in vivo material, such as the presence of different cell components normally present in the target organ, as well as the removal of a layer of functional complexity (acquired immunity), making it possible to focus on tissue specific, early innate immune mechanisms. These preliminary results highlight the importance of considering genetic origin when selecting the fish source for the production of SCPCs, as well as their usefulness as screening tools for assessment of genotypic differences in disease resistance.</p

Heterogeneous Behavioral Rules in the Oligopolistic Case
No full textIn a static symmetric duopoly the set of behavioral rules is extended to different types of markup pricing. Using an equilibrium concept suggested in Pasche (2001), it is shown that dependend on the markup neither pure Cournot nor pure Bertrand behavior is a behavioral equilibrium profile. Instead, there is a rationale for the usage of simple heuristics. The presence of markup rules leads to Stackelberg outcomes. Furthermore, pure markup behavior is more competitive than in Cournot case but less competitive than in Bertrand case. It is shown, that multiple behavioral equilibria and heterogeneous behavior may arise, where at least one player uses price setting strategies.oligopoly, markup rules, heterogeneity, behavioral equilibrium.
A Bertrand-Edgeworth-oligopóliumok (Bertrand-Edgeworth oligopolies – a survey of the literature)
No full textAz irodalomban az olyan oligopolmodellek, amelyekben mind az ár, mind a mennyiség döntési változó, Bertrand-Edgeworth-oligopóliumok néven ismertek. E tanulmányban a Bertrand-Edgeworth-oligopóliumokkal kapcsolatos érdekesebb eredményeket tekintjük át. Tárgyaljuk a Bertrand-Edgeworth-típusú oligopolmodellek specifikációját, a Nash-egyensúly létezését, a Nash-egyensúly meghatározását és a Bertrand-Edgeworth-oligopóliumok alkalmazásait. / === / Oligopoly models in which both price and quantity are decisive variables are known in the literature as Bertrand-Edgeworth oligopolies, the most interesting results with which are surveyed in this paper. The author assumes the existence of the Nash equilibrium, as the specification of Bertrand-Edgeworth-type oligopoly models, the determination of the Nash equilibrium, and the application of Bertrand-Edgeworth oligopolies

Planejamento territorial rural: análise do processo de elaboração de planos diretores em municípios rurais, o caso de Papanduva - Santa Catarina
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Arquitetura e Urbanismo.Este trabalho teve como objetivo principal a análise do processo de elaboração do primeiro Plano Diretor de Papanduva, pequeno município predominantemente agrícola localizado no planalto norte catarinense, no período compreendido entre fevereiro e outubro de 2006. A emergência das discussões sobre a importância do mundo rural e suas relações com o urbano, a falta de referencial teórico e prático sobre o planejamento territorial rural e os poucos exemplos de experiências de elaboração de Planos Diretores em municípios rurais, motivaram estas reflexões. Durante a revisão teórica ficou claro que o conceito de ruralidade ainda está em construção, ainda há muito pré-conceito e desconhecimento em relação a este mundo e seus potenciais. O Brasil urbano precisa se voltar para o campo, tratando-o de igual para igual, direcionando seu desenvolvimento para o interior. Ao longo do trabalho são apresentados: a realidade do município de Papanduva, a metodologia utilizada no Plano Diretor, uma análise dos resultados para verificar se a metodologia esteve adequada à realidade agrícola do município e finalmente as conclusões, entre elas, a de que não existe uma única metodologia de planejamento territorial aplicável aos municípios rurais. O que pode haver é uma concepção a partir da realidade rural, que é muito diversa e heterogênea, fazendo um contraponto à concepção excessivamente urbano do Estatuto da Cidade. This work had as main objective the analysis of the process of elaboration of the first Master plan of Papanduva, small-located rural municipal district in the plateau north Santa Catarina, in the period understood between February and October of 2006. The emergency of the discussions about the importance of the rural world and their relationships with the urban, the lack of theoretical and practical referential on the rural territorial planning and the few examples of experiences of elaboration of Master plans in rural municipal districts, they motivated these reflections. During the revision theoretical, of course this concept is still in construction, there are still a lot of pré-concept and ignorance in relation to this fantastic world and of so many potentials. Urban Brazil needs to return for the field, treating him of equal for equal, addressing his/her development for the municipal districts of the interior. Along the healthy work presented the municipal district of Papanduva, the methodology used in the Master plan, an analysis of the results to verify the methodology was adapted to the agricultural reality of the municipal district and finally the conclusions, among them, the that a single applicable methodology doesn't exist to the rural municipal districts. The one that can have is a conception starting from the rural reality, that it is very several and variable in the whole national territory, making a counterpoint excessively to the conception urban of the Statute of the City
