Vehicle emissions and PM2.5 mass concentrations in six Brazilian cities

In Brazil, the principal source of air pollution is the combustion of fuels (ethanol, gasohol, and diesel). In this study, we quantify the contributions that vehicle emissions make to the urban fine particulate matter (PM2.5) mass in six state capitals in Brazil, collecting data for use in a larger project evaluating the impact of air pollution on human health. From winter 2007 to winter 2008, we collected 24-h PM2.5 samples, employing gravimetry to determine PM2.5 mass concentrations; reflectance to quantify black carbon concentrations; X-ray fluorescence to characterize elemental composition; and ion chromatography to determine the composition and concentrations of anions and cations. Mean PM2.5 concentrations in the cities of Sao Paulo, Rio de Janeiro, Belo Horizonte, Curitiba, Porto Alegre, and Recife were 28, 17.2, 14.7, 14.4, 13.4, and 7.3 mu g/m(3), respectively. In Sao Paulo and Rio de Janeiro, black carbon explained approximately 30% of the PM2.5 mass. We used receptor models to identify distinct source-related PM2.5 fractions and correlate those fractions with daily mortality rates. Using specific rotation factor analysis, we identified the following principal contributing factors: soil and crustal material; vehicle emissions and biomass burning (black carbon factor); and fuel oil combustion in industries (sulfur factor). In all six cities, vehicle emissions explained at least 40% of the PM2.5 mass. Elemental composition determination with receptor modeling proved an adequate strategy to identify air pollution sources and to evaluate their short- and long-term effects on human health. Our data could inform decisions regarding environmental policies vis-a-vis health care costs.

Prevalence and risk factors of Hepatitis C virus infection in Brazil, 2005 through 2009: a cross-sectional study

Abstract Background Hepatitis C chronic liver disease is a major cause of liver transplant in developed countries. This article reports the first nationwide population-based survey conducted to estimate the seroprevalence of HCV antibodies and associated risk factors in the urban population of Brazil. Methods The cross sectional study was conducted in all Brazilian macro-regions from 2005 to 2009, as a stratified multistage cluster sample of 19,503 inhabitants aged between 10 and 69 years, representing individuals living in all 26 State capitals and the Federal District. Hepatitis C antibodies were detected by a third-generation enzyme immunoassay. Seropositive individuals were retested by Polymerase Chain Reaction and genotyped. Adjusted prevalence was estimated by macro-regions. Potential risk factors associated with HCV infection were assessed by calculating the crude and adjusted odds ratios, 95% confidence intervals (95% CI) and p values. Population attributable risk was estimated for multiple factors using a case–control approach. Results The overall weighted prevalence of hepatitis C antibodies was 1.38% (95% CI: 1.12%–1.64%). Prevalence of infection increased in older groups but was similar for both sexes. The multivariate model showed the following to be predictors of HCV infection: age, injected drug use (OR = 6.65), sniffed drug use (OR = 2.59), hospitalization (OR = 1.90), groups socially deprived by the lack of sewage disposal (OR = 2.53), and injection with glass syringe (OR = 1.52, with a borderline p value). The genotypes 1 (subtypes 1a, 1b), 2b and 3a were identified. The estimated population attributable risk for the ensemble of risk factors was 40%. Approximately 1.3 million individuals would be expected to be anti-HCV-positive in the country. Conclusions The large estimated absolute numbers of infected individuals reveals the burden of the disease in the near future, giving rise to costs for the health care system and society at large. The known risk factors explain less than 50% of the infected cases, limiting the prevention strategies. Our findings regarding risk behaviors associated with HCV infection showed that there is still room for improving strategies for reducing transmission among drug users and nosocomial infection, as well as a need for specific prevention and control strategies targeting individuals living in poverty.

Somente um deve vencer: as bases de recrutamento dos candidatos à Prefeitura das capitais brasileiras em 2008

Não é segredo para os estudiosos e é reconhecido pelos atores envolvidos no jogo político que o Prefeito desempenha importantes atividades, podendo influenciar o dia-a-dia da população, a relação com outras esferas de governo e as eleições gerais. Tomando como universo empírico os candidatos ao cargo de Prefeito das capitais brasileiras em 2008, procuramos identificar e analisar as bases de recrutamento desses concorrentes ao principal posto político do município. As interpretações correntes na literatura concentram-se sobre os vencedores da disputa eleitoral, deixando de lado os derrotados. O que os vencedores têm que os derrotados não têm? Seria o perfil dos vencedores diferente daquele encontrado no grupo dos derrotados? Com o propósito de oferecer uma contribuição aos estudos das bases de recrutamento dos membros pertencentes às elites locais, o texto está organizado em uma única seção, onde vamos discutir três dimensões: (i) gênero, faixa etária e naturalidade; (ii) nível de instrução, grupo profissional e mandato executivo e (iii) gastos com campanha e tamanho do patrimônio. Essas características podem ajudar a construir um perfil sociopolítico dos membros pertencentes aos grupos dos vencedores e dos derrotados nas eleições municipais de 2008 para o cargo de Prefeito das capitais brasileiras. Além disso, o estudo desses atributos pode indicar quais predominaram na disputa eleitoral, isto é, quais deles podem mostrar as características que circundam o processo seletivo dos integrantes do distinto grupo político.

Causas externas em adolescentes: atendimentos em serviços sentinelas de urgência e emergência nas Capitais Brasileiras - 2009

Os adolescentes estão em busca de novas referências e experiências, o que pode implicar atitudes de risco e exposição às causas externas - acidentes e violências. Estes eventos constituem um grave problema em Saúde Pública. O objetivo deste estudo foi analisar as ocorrências de causas externas em adolescentes de 10 a 19 anos atendidos em serviços sentinela de urgência e emergência no Brasil. Foram analisados dados do inquérito da Vigilância de Violências e Acidentes (Inquérito VIVA 2009) em 74 Unidades de Emergência em 23 capitais e no Distrito Federal. Os achados mostraram que 6.434 (89,8%) adolescentes foram vítimas de acidentes e 730 (10,2 %) de violências. As principais causas de acidentes foram as quedas, outros acidentes e o trânsito e entre as violências predominaram as agressões. Tanto para acidentes como para violências os adolescentes do sexo masculino e a raça/cor não branca foram predominantes; as ocorrências foram mais frequentes na via pública. A alta foi a evolução mais frequente, com maior ocorrência de internação hospitalar nas vítimas de violências entre 15 a 19 anos. Conhecer a realidade epidemiológica das causas externas entre os adolescentes representa uma importante ferramenta para as políticas de prevenção, promoção à saúde e da cultura de paz, visando à redução da morbimortalidade.

Tendências da frequência do consumo de feijão por meio de inquérito telefônico nas capitais brasileiras, 2006 a 2009

Analisar a tendência da frequência do consumo do feijão nos anos de 2006 a 2009 nas capitais brasileiras. Trata-se de uma série histórica utilizando a base de dados do Vigitel de todas as capitais brasileiras. O consumo de feijão foi descrito por meio da frequência relativa e a tendência foi avaliada utilizando-se regressão de Poisson. O consumo de feijão cinco ou mais vezes por semana variou de 71,85% (2006) a 65,79 (2009). Na maior faixa de frequência de consumo ao longo de todo o período estudado estão incluídas as capitais Goiânia, Belo Horizonte, Palmas, Cuiabá e Brasília. As pessoas com IMC na categoria adequado/baixo peso apresentaram as maiores frequências de consumo em relação aos indivíduos com sobrepeso e obesidade. Foi observada tendência significativa de redução do consumo regular de feijão segundo ano de realização da pesquisa, exceto para a categoria de idade entre os 45 e 54 anos. Ocorreu redução significativa da frequência do consumo do feijão pela população brasileira e a adoção de políticas de monitoramento e incentivo do consumo é necessária em função dos benefícios apresentados pela leguminosa.

Premio "Capitale verde europea". Studio di una politica dell'Unione europea in tema di sostenibilità ambientale con approfondimento terminologico sul minieolico.

This dissertation is divided into four chapters and combines the study of the European Green Capital Award with a terminology research on small wind turbines, a technical subject in the macro-area of sustainable cities. Chapter I aims at giving an overview of the development of environmental policies and treaties both at the international and European level. Then, after highlighting the crucial role of cities for the global environment, the chapter outlines the urban dimension of the EU environmental policies and defines the vision of a sustainable city promoted by the European Union. Chapter II contains an in-depth analysis of the European Green Capital Award and illustrates its aims, the entire designation process, its communication campaign and its evolution. Chapter III focuses on applicant, finalist and winning cities in order to study the aspect of participation in the competition. It also contains a detailed analysis of two European Green Capitals, i.e. Nantes and Bristol, who respectively won the title in 2013 and 2015. Based on a variety of sources, this chapter examines the successful aspects of their bids and communication campaigns during their year as Green Capitals. Chapter IV presents the terminology research in the field of small wind turbines and the resulting bilingual glossary in English and Italian. The research was carried out using two terminology tools: TranslatorBank and InterpretBank. The former is composed by two software programmes, CorpusCreator and MiniConcordancer DB, which were used to semi-automatically create specialized corpora from the Web and then extract terminology and occurrences of terms from the collected texts. The latter is a software which has been specifically designed for interpreters in order to help them optimize their professional workflow, from gathering information and creating glossaries on a specific subject to the actual interpreting task at a conference. InterpretBank’s tool TermMode was used to create a glossary with term equivalents and additional information such as definitions and the contexts of use.

Finnish Americans and the Farm Revolt of the 1930s

Farm protest in the United States attracted widespread attention in the 1930s as militant farmers interfered with foreclosure sales, demonstrated at county court houses and state capitals, and blocked highways and stopped trains to prevent crops and livestock from going to market in an effort to raise farm prices. The best known of the protest groups was the Farmers Holiday Association, which was formed in 1932. Prior to the Holiday, however, a left-wing group organized by Communists in 1930 known as the United Farmers League (UFL) gained an initial following in the cutover country of the Upper Peninsula of Michigan, northern Wisconsin, northern Minnesota, and parts of the Dakotas and northeast Montana. Finnish Americans dominated the UFL in the Upper Midwest and in a few locales in the Dakotas. Evidence for this high level of influence comes from the fact that the head of the Communist Party’s Agrarian Department was Henry Puro, a key figure in Finnish American Communist circles and a member of the Party’s Politburo. This paper will focus on Finnish American involvement in the UFL and, to a lesser extent, the broader-based Farmers Holiday movement.

Taking a New Look at Neo-Assyrian Gates

The Assyrian capitals are not only known for their magnificent temples and palaces, but also for their monumental city walls. The most impressive and at the same time most delicate features of all the town defenses were the city gates. As they interrupted the line of defense, they were al-ways a vulnerable spot of every system of fortifications. However, the walled cities’ economic needs demanded these gateways to be built, in order to ensure the steady flow of goods and pro-visions. Apart from that, they also had a significant ideological meaning, which is emphasized by many cuneiform texts. During the excavations of the Assyrian capitals of Ashur, Dūr Šarrūkīn, and Nineveh, a fairly large number of Assyrian city gates were brought to light. By re-examining the archaeological reports and employing remote sensing, many details of these structures can still be revealed. The paper aims at illuminating the different considerations that went into constructing these gates, as well as the development Assyrian city gates underwent and what may have influenced this process.

Capital interplays and the self-rated health of young men: results from a cross-sectional study in Switzerland.

INTRODUCTION We apply capital interplay theory to health inequalities in Switzerland by investigating the interconnected effects of parental cultural, economic and social capitals and personal educational stream on the self-rated health of young Swiss men who live with their parents. METHODS We apply logistic regression modelling to self-rated health in original cross-sectional survey data collected during mandatory conscription of Swiss male citizens in 2010 and 2011 (n = 23,975). RESULTS In comparison with sons whose parents completed mandatory schooling only, sons with parents who completed technical college or university were significantly more likely to report very good or excellent self-rated health. Parental economic capital was an important mediating factor in this regard. Number of books in the home (parental cultural capital), family economic circumstances (parental economic capital) and parental ties to influential people (parental social capital) were also independently associated with the self-rated health of the sons. Although sons in the highest educational stream tended to report better health than those in the lowest, we found little evidence for a health-producing intergenerational transmission of capitals via the education stream of the sons. Finally, the positive association between personal education and self-rated health was stronger among sons with relatively poorly educated parents and stronger among sons with parents who were relatively low in social capital. CONCLUSIONS Our study provides empirical support for the role of capital interplays, social processes in which capitals interpenetrate or co-constitute one another, in the intergenerational production of the health of young men in Switzerland.

Operationalizing ecosystem services for the mitigation of soil threats: A proposed framework

Despite numerous research efforts over the last decades, integrating the concept of ecosystem servicesinto land management decision-making continues to pose considerable challenges. Researchers havedeveloped many different frameworks to operationalize the concept, but these are often specific to acertain issue and each has their own definitions and understandings of particular terms. Based on acomprehensive review of the current scientific debate, the EU FP7 project RECARE proposes an adaptedframework for soil-related ecosystem services that is suited for practical application in the preventionand remediation of soil degradation across Europe. We have adapted existing frameworks by integratingcomponents from soil science while attempting to introduce a consistent terminology that is understand-able to a variety of stakeholders. RECARE aims to assess how soil threats and prevention and remediationmeasures affect ecosystem services. Changes in the natural capital’s properties influence soil processes,which support the provision of ecosystem services. The benefits produced by these ecosystem servicesare explicitly or implicitly valued by individuals and society. This can influence decision- and policymak-ing at different scales, potentially leading to a societal response, such as improved land management.The proposed ecosystem services framework will be applied by the RECARE project in a transdisciplinaryprocess. It will assist in singling out the most beneficial land management measures and in identifyingtrade-offs and win–win situations resulting from and impacted by European policies. The framework thusreflects the specific contributions soils make to ecosystem services and helps reveal changes in ecosystemservices caused by soil management and policies impacting on soil. At the same time, the framework issimple and robust enough for practical application in assessing soil threats and their management withstakeholders at various levels.

La vida cultural de las políticas públicas : un análisis de los conflictos por el uso del agua en el contexto neoliberal

La descentralización en el marco de las políticas neoliberales se concibió como una reforma política-administrativa para minimizar el rol del Estado postulando como bastión clave "La participación local". Sin embargo ésta sólo se queda en los ámbitos formales. El caso particular de las políticas de descentralización del riego en la provincia de Mendoza no es una excepción. Lo que nos lleva a analizar su microcosmos y las redes sociales informales que dan cuenca de la desigual participación de los distintos usuarios del agua de riego en las decisiones en torno a este recurso, según sus trayectorias y sus capitales sociales, económicos y culturales.

Nuevo enlace ferrovial interprovincial Santa Fe-Entre Ríos : Una oportunidad de escala regional

La provincia de Santa Fe, Argentina, se encuentra en una localización estratégica. La potencialidad de la Hidrovía Paraná-Paraguay, los corredores bioceánicos viales y la red existente de trazados ferroviarios le confieren gran dinamismo a su integración económica, social, cultural y política, no sólo hacia el interior del propio territorio, sino también en relación a las demás provincias y más allá de los confines nacionales. La región capital, cuyo núcleo es la ciudad de Santa Fe, se encuentra caracterizada por factores realmente dinámicos: el riesgo hídrico que es intrínseco del área, la intensificación de los flujos económicos pasantes, los procesos de concentración demográfica y la creciente interdependencia entre ciudades, como es el casode Santa Fe y Paraná (capital de la vecina provincia de Entre Ríos), bajo un progresivo proceso de metropolización binuclear. Estos factores, sumados a la escasa cantidad de conexiones físicas sobre el sistema fluvial del río Paraná, han instalado la creciente necesidad de contar con un nuevo enlace interprovincial, adaptado a una hipótesis de reactivación ferroviaria. El proyecto se encuentra en fase preliminar. La cuestión principal gira en torno a la decisión de su localización específica, que deberá considerar el profundo efecto transformador propio de una obra civil de gran calibre, tanto en relación a la plataforma natural como al sistema de asentamientos humanos. También sus alcances territoriales y el impacto potencial en la micro, meso y macroescala. El propósito de la investigación reside en profundizar sobre las dimensiones involucradas por el proyecto (técnica, social, económica, ambiental, de movilidad), en la búsqueda de una toma de posición que permita echar luz sobre los escenarios más beneficiosos y/o menos desfavorables, en relación a las numerosas propuestas de localización que se encuentran actualmente en discusión. El resultado es una matriz analítica basada en variables cuantitativas y cualitativas, que permite una evaluación integral de las propuestas en función de considerar, en síntesis, el grado de impacto sobre la plataforma natural sustentante, sus capacidades para revertir las problemáticas territoriales actuales, y finalmente sus posibilidades para generar nuevos ejes de desarrollo en la región o bien potenciar los existentes. Se concluye que análisis preliminares de tipo pluridimensional son necesarios para someter a discusión, como instancia previa a estudios específicos de factibilidad y viabilidad, puesto que permiten una visualización integral de las variables intervinientes, marcando el camino hacia su adecuada ponderación. Palabras clave: enlace, multimodalidad, región, transformaciones

Capital extranjero y agroindustria : Notas para una discusión sobre los cambios en la burguesía vitivinícola de Argentina a partir de la década del '90

Se propone problematizar cómo afectan a la burguesía vitivinícola de Argentina los cambios producidos en la actividad a partir de la década de los '90, en el marco de los procesos de globalización. Una de las conclusiones principales es que, aunque el ingreso de capitales extranjeros a la actividad vitivinícola ha sido importante, la burguesía cuyos capitales son nacionales y/o locales logra conservar posiciones no desventajosas en la estructura económica de esta agroindustria. Se trabajó principalmente con fuentes estadísticas de organismos oficiales; y con datos obtenidos de páginas web de las empresas, de consultoras especializadas y de entrevistas a informantes calificados. Asimismo, se realizó una exhaustiva revisión bibliográfica sobre la temática
