When Politicians Talk About Politics: Identifying Political Tweets of Brazilian Congressmen

Since June 2013, when Brazil faced the largest and most significant mass protests in a generation, a political crisis is in course. In midst of this crisis, Brazilian politicians use social media to communicate with the electorate in order to retain or to grow their political capital. The problem is that many controversial topics are in course and deputies may prefer to avoid such themes in their messages. To characterize this behavior, we propose a method to accurately identify political and non-political tweets independently of the deputy who posted it and of the time it was posted. Moreover, we collected tweets of all congressmen who were active on Twitter and worked in the Brazilian parliament from October 2013 to October 2017. To evaluate our method, we used word clouds and a topic model to identify the main political and non-political latent topics in parliamentarian tweets. Both results indicate that our proposal is able to accurately distinguish political from non-political tweets. Moreover, our analyses revealed a striking fact: more than half of the messages posted by Brazilian deputies are non-political.Comment: 4 pages, 7 figures, 2 table

ANÁLISE MICROBIOLÓGICA DE ÁGUA DE CISTERNAS NA LOCALIDADE CIPÓ DOS TOMAZ, MUNICÍPIO DO CRATO-CE.

A água constitui fator essencial para todo o ser vivo, mas é também um veículo de doenças parasitárias e infecciosas, aumentando a freqüência de moléstias crônicas. A água é ingerida pelo homem em maior quantidade que todos os outros alimentos reunidos e é, também, a sua principal excreção. A água de consumo humano é um dos importantes veículos de enfermidades diarréicas de natureza infecciosa, o que torna primordial a avaliação de sua qualidade microbiológica. O objetivo almejado no presente trabalho compreende a realização da análise microbiológica das águas de cisternas construídas pelo Projeto 1 Milhão de Cisternas (P1MC), no município de Crato-CE, a fim de avaliar a qualidade da água consumida pela população.   A água foi coletada de acordo com o Manual de Coleta de Amostra Ambiental-Água, do Laboratório Central de Saúde Pública - LACEN. Os resultados obtidos mostraram que das 10 amostras analisadas, 7 obtiveram resultados satisfatórios e 3 apresentaram resultados insatisfatórios para Escherichia coli. A educação é uma forma de prevenção, contudo, seria necessária uma monitoração mais freqüente da qualidade da água. O desenvolvimento de um trabalho de educação sanitária para a população do meio rural e a adoção de medidas preventivas visando à preservação dessas águas aliados às técnicas de tratamento de dejetos, são as ferramentas necessárias para diminuir ao máximo o risco de ocorrência de enfermidades de veiculação hídrica

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning
