Brazilian cases and the debate about risk communication and governance in areas contaminated by lead

This investigation focused on lead contamination case studies in Brazil. The situations studied involve communities living in Santo Amaro da Purificação and Adrianópolis, in the north-east and south of Brazil, respectively. These communities have all had to live with environmental contamination and human exposure to lead as a consequence of industrial, mining and processing activities that were conducted by the same company for decades in a manner inconsistent with modern mining and industrial standards, with little control of environmental and human health impacts. The investigation sought to analyze the strategies of risk communication to local people, and to evaluate their engagement in risk management. The methodological approach included the analysis of newspaper articles, and interviews conducted with different stakeholders, such as residents, journalists, researchers and authorities. The results indicated the need to promote public involvement in the debate and in the decision-making process. The results also confirmed the hypothesis that associative models (represented by local neighborhood associations, for instance) are important for promoting and eliciting public participation in risk management.No artigo são apresentados dois estudos de caso sobre contaminação por chumbo no Brasil. As situações estudadas referem-se a Santo Amaro da Purificação, nordeste, e Adrianópolis, sul, onde comunidades convivem com a contaminação ambiental e a exposição humana ao chumbo em decorrência das atividades industriais e de mineração desenvolvidas durantes décadas, por uma mesma empresa, de forma inconsistente com os padrões ambientais e de mineração, com pouco controle dos impactos ambientais e à saúde humana advindos. Os principais objetivos da investigação realizada foram analisar as estratégias de comunicação de risco adotadas junto às comunidades locais e avaliar o engajamento delas no processo de gerenciamento do risco. A metodologia aplicada incluiu análise de notícias jornalísticas e entrevistas realizadas com diferentes atores sociais, como moradores, jornalistas, pesquisadores e autoridades. Os resultados indicaram a necessidade de promover o envolvimento público no debate e no processo decisório. Os resultados validaram também a hipótese de que os modelos associativos (representados por associações de moradores, por exemplo) são importantes na promoção e no estímulo da participação pública no gerenciamento do risco.337349Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Experiências de uma Liga Acadêmica de Nutrição e Alimentação Materno Infantil: Um Relato de Caso

As Ligas Acadêmicas (LA) são entidades autônomas organizadas por estudantes com o objetivo de ampliar o conhecimento e promover um objetivo central. No curso de Nutrição, o fenômeno de articulação de LA ainda é mais principiante. Este relato de experiência apresenta a vivência de gestão da Liga Acadêmica de Nutrição e Alimentação Materno Infantil (LAMIN) da Escola de Nutrição de uma universidade pública. Através de encontros científicos, publicações em mídias sociais e organização de eventos, a LAMIN tornou-se uma ponte entre cursos de diversas áreas e um espaço de aprimoramento dos discentes ligantes na área de nutrição Materno Infantil. Além disso, oportunizou o desenvolvimento de habilidades administrativas e gerenciais ao ligantes, trazendo também experiências de situações reais do mercado de trabalho

The aim of this technical note is to describe the procedures performed and to indicate the use of the viewer of the Preliminary Thematic Map of Sites of Memory of the Atlantic Slave Trade and the History of Enslaved Africans in Brazil. This map was made based on a survey of one hundred of sites of memory conducted by the LABHOI/UFF, in partnership with the "Slave Route project: Resistance, Liberty, Heritage", UNESCO (2014)

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Studies of the mass composition of cosmic rays and proton-proton interaction cross-sections at ultra-high energies with the Pierre Auger Observatory

In this work, we present an estimate of the cosmic-ray mass composition from the distributions of the depth of the shower maximum (Xmax) measured by the fluorescence detector of the Pierre Auger Observatory. We discuss the sensitivity of the mass composition measurements to the uncertainties in the properties of the hadronic interactions, particularly in the predictions of the particle interaction cross-sections. For this purpose, we adjust the fractions of cosmic-ray mass groups to fit the data with Xmax distributions from air shower simulations. We modify the proton-proton cross-sections at ultra-high energies, and the corresponding air shower simulations with rescaled nucleus-air cross-sections are obtained via Glauber theory. We compare the energy-dependent composition of ultra-high-energy cosmic rays obtained for the different extrapolations of the proton-proton cross-sections from low-energy accelerator data

Study of downward Terrestrial Gamma-ray Flashes with the surface detector of the Pierre Auger Observatory

The surface detector (SD) of the Pierre Auger Observatory, consisting of 1660 water-Cherenkov detectors (WCDs), covers 3000 km2 in the Argentinian pampa. Thanks to the high efficiency of WCDs in detecting gamma rays, it represents a unique instrument for studying downward Terrestrial Gamma-ray Flashes (TGFs) over a large area. Peculiar events, likely related to downward TGFs, were detected at the Auger Observatory. Their experimental signature and time evolution are very different from those of a shower produced by an ultrahigh-energy cosmic ray. They happen in coincidence with low thunderclouds and lightning, and their large deposited energy at the ground is compatible with that of a standard downward TGF with the source a few kilometers above the ground. A new trigger algorithm to increase the TGF-like event statistics was installed in the whole array. The study of the performance of the new trigger system during the lightning season is ongoing and will provide a handle to develop improved algorithms to implement in the Auger upgraded electronic boards. The available data sample, even if small, can give important clues about the TGF production models, in particular, the shape of WCD signals. Moreover, the SD allows us to observe more than one point in the TGF beam, providing information on the emission angle
