The insurance industry in Brazil: a long-term view

This paper surveys the formation and development of insurance business in Brazil. It describes its very first steps, from the colonial times and imperial era to recent events. Particular attention is given to regulatory changes, showing how they evolved in response to macroeconomic shocks that affected the Brazilian economy during this period.Insurance, Brazil, Regulation.

Market Power and Commodity Prices: Brazil, Chile and the United States, 1820s-1930

The paper focuses on market power by certain countries in specific commodity markets as a crucial factor in explaining the level of protection. It is argued that a country which is a price maker in the world market of a specific commodity might affect its world price through export taxes, import taxes and commodity stockpiling. Standard reduced form equations were estimated to test if significant market shares in international markets of Brazilian coffee, Chilean saltpetre and US cotton implied domestic variables were relevant for the determination of the corresponding world commodity prices. Results suggest the producers succeeded in passing through increases in internal costs to the relevant world commodity price.

D-meson diffusion in hadronic matter

We present effective-field-theory results with unitarized interactions on the D-meson transport coefficients in a gas populated by light mesons and baryons at finite temperature and baryochemical potential. The Fokker-Planck equation is used to compute the drag force, the relaxation time and the diffusion coefficients of D mesons for collisions at FAIR. At finite baryochemical potential, the combined effect of net baryonic density and sizable meson-baryon interaction makes the D mesons to relax more efficiently than in the case at zero baryochemical potential. We also describe the connection with the quark-gluon plasma phase in adiabatic trajectories on the phase diagram at both zero and finite baryochemical potential.Comment: 5 pages, 4 figures.

Heating triangle singularities in heavy ion collisions

We predict that triangle singularities of hadron spectroscopy are strongly affected in heavy ion collisions. To do it we examine various effects of finite temperature on the triangle loop yielding the singularity within the hadron phase. Pion-containing triangles can be enhanced by exchanging them with the medium, but in other cases, especially with heavy-quark hadrons, known thermal effects over the particles mass and width can quickly reduce the singularity: at temperatures of about 150 MeV, below the transition to a quark-gluon plasma, even by two orders of magnitude. It appears that peaks seen in central heavy ion collisions are more likely to be hadrons than rescattering effects unless perhaps if a pion is involved in the triangle. The medium then acts as a spectroscopic filter.Comment: 5 pages, 7 plot

Ciclo Sonoro

O projeto de extensão “Ciclo Sonoro” fundamenta-se na organização e realização de recitais, palestras e masterclasses em distintos espaços na região trinacional, visando a divulgação da música popular e de concerto. Entre os principais objetivos, destacam-se a ampliação do acesso à música de qualidade na região, o despertamento do interesse da comunidade por atividades relacionadas à música, o oferecimento de oportunidades de performance em público para músicos em início de carreira e o estreitamento das relações com músicos e público das cidades de Foz do Iguaçu, Puerto Iguazú e Ciudad del Este. Os eventos serão realizados em diferentes locais da região trinacional, aspirando a exposição de atividades musicais para diferentes camadas da população

Perfil epidemiológico das agressões por arma de fogo e arma branca no interior da Bahia

O presente estudo teve como objetivo traçar o perfil epidemiológico das agressões por arma de fogo e arma branca, no período de 2009 a 2011, em um Hospital Geral no interior da Bahia. Trata-se de um estudo descritivo, transversal, elaborado a partir de dados secundários de hospitalizações por agressão, nos anos de 2009 à 2011, no Hospital Geral Prado Valadares (HGPV) em Jequié, Bahia. A análise foi realizada por meio de estatística descritiva e os dados apresentados em frequências absolutas e relativas. Dos resultados obtidos, 299 hospitalizações se deram por agressão por arma de fogo e arma branca, sendo o maior percentual de vítimas, jovens do sexo masculino, na faixa etária entre 20-29 anos (39,5%). É necessário a elaboração e implementação de políticas públicas envolvendo os diversos segmentos da sociedade civil e organizada para o enfrentamento deste problema de saúde pública com vistas a adoção de estratégias de prevenção e redução dos índices de morbimortalidade

DRIVERS OF DIFFERENT TYPES OF COLLABORATIVE CONSUMPTION

In this paper, we set out with two objectives: investigate the determinants to explain the satisfaction with different types of collaborative consumption and investigate the determinants to explain the intention to recommend different types of collaborative consumption. It develops and tests a research model using structural equation modeling. The survey data were collected from 431 collaborative consumers. Based on our results model, economic benefits and utility are the key motivators for these consumers. That is, collaborative consumers from Brazil are not very concerned about the environmental impacts, appear very independently-minded and opportunistic, and do not feel the impact of social influence upon their activities. Our model makes a contribution to the emergent stream of literature on the sharing economy, because, to our knowledge, this is the first study to formally test the drivers of collaborative consumption considering more than three kinds of collaborative practices.

Transição sociotecnológica para a mobilidade urbana sustentável no Brasil

This article identifies micro, meso, and macro dynamics that influence the socio-technical transitions of cities to sustainable urban mobility in Brazil. The study analyzed the content of documents such as the National Urban Mobility Policy (PNMU), and the master plans and urban mobility plans of the cities of São Paulo, Rio de Janeiro, Distrito Federal, Fortaleza, and Salvador. The research revealed that the master plans and other plans related to urban mobility of the main Brazilian capitals are developed in isolation, with no coordination among cities. At the micro level, the plans do not contemplate the adoption of alternative fuels and the effective integration among modes of public transport. At the meso level, three mobility regimes were introduced: the traditional public transport and non-motorized public transport regimes, which had a dynamic contrary to the regime of cars. At the macro level, the variables associated with the economic and social context, with the consumer market, and the industry shaped the trends of urban mobility systems. The research presents a dynamic of resistance to sustainable urban mobility and reinforces the need for greater coordination between private and public actors.O artigo avalia dinâmicas nos níveis micro, meso e macro que afetam o processo de transição sociotecnológica para a mobilidade urbana sustentável no Brasil. Procedeu-se uma análise de conteúdo da Política Nacional de Mobilidade Urbana (PNMU) e dos planos diretores e de mobilidade urbana das cidades de São Paulo, Rio de Janeiro, Brasília, Fortaleza e Salvador. A pesquisa revelou que os planos diretores e de mobilidade urbana das principais capitais do país são desenvolvidos de forma isolada e sem articulação entre os atores. No nível micro, os planos não contemplam a adoção de combustíveis alternativos e a integração eficaz de modais de transportes públicos.  No nível meso, três regimes de mobilidade foram introduzidos: os regimes de transporte público tradicional e transporte público não motorizado, que tiveram uma dinâmica contrária ao regime de carros particulares. No nível macro, as variáveis associadas ao contexto econômico, sociais, mercado consumidor e indústria moldam as macrotendências dos sistemas de mobilidade urbana. A pesquisa apresenta uma dinâmica de resistência à mobilidade urbana sustentável, e reforça a necessidade de uma maior articulação entre os atores públicos e privados
