Seen through a shattered bus window, another bus burns after it was set fire by protesters during a general strike in Rio de Janeiro, Brazil, Friday, April 28, 2017. Public transport largely came to a halt across much of Brazil on Friday and protesters blocked roads and scuffled with police as part of a general strike to protest proposed changes to labor laws and the pension system. (AP Photo/Leo Correa) RIO DE JANEIRO (AP) — Protesters lit buses on fire, blocked roads and clashed with police on Friday during a general strike that brought transportation to a halt in many cities across Latin America's largest nation. The strike was to protest major changes to labor law and the pension system being considered by Congress, but it was also a raw display of anger by many Brazilians fed up with corruption and worried about the future amid a deep recession and rising unemployment. In Rio de Janeiro, after hours of clashes with police in front of the legislative building, several buses were torched. In Sao Paulo, thousands marched toward the home of President Michel Temer, throwing rocks at police who shot stun grenades when protesters tried to go beyond barriers set up. Millions stayed home, either in support of the strike or simply because they were unable to get to work. The tens of thousands who took to the street raised questions about whether Temer will be able to push his proposals through Congress, where they had previously looked likely to pass. Temer's administration argues that more flexible labor rules will revive a moribund economy and warns the pension system will go bankrupt without changes. Unions and other groups called for the strike, saying the changes before Congress will make workers too vulnerable and strip away too many benefits. In a statement Friday night, Temer characterized the protesters as "small groups" that blocked the roads and streets. He said his administration was working to help Brazilians workers overcome the country's economic malaise. Earlier in the day, most commuter trains and metro lines were stopped in Sao Paulo during the height of morning commute, and all buses stayed off the roads. Buses ran partial service during the morning in Rio but later began returning to normal. The metro was closed for the day in the capital of Brasilia. Some protesters also set up barricades and started fires in the streets, including on roads heading to the main airports in Sao Paulo. In Rio, protesters created confusion by running through Santos Dumont Airport, and others blocked a major road. Some plane mechanics joined the strike, according to the National Aeronautic Union, but the impact was minimal, with only a handful of flights canceled or delayed at the two cities' airports. "We are demanding our rights, as workers, because the president of the country proposed a law for people to work more and live less, so you will only receive your pension when you die," said Edgar Fernandes, a dock worker who was protesting in Rio. The CUT union said around 35 million Brazilians didn't show up for work on Friday, more than one-third of the working population. But government officials downplayed the strike, insisting that many Brazilians were still at work. "We don't have a strike, we have widespread riots," Justice Minister Osmar Serraglio said on Joven Pam radio. Brazil's economy is in a deep recession, and many Brazilians are frustrated with Temer's government. Temer, whose approval ratings are hovering around 10 percent, has argued the proposed changes will benefit Brazilians in the long run. But with so many out of work, many feel they can ill afford any cuts to their benefits. Meanwhile, the country is mired in a colossal scandal involving billions of dollars in kickbacks to politicians and other public officials. Over the last three years, dozens of top politicians and businessmen have been jailed in the so-called Car Wash investigation that has produced near daily revelations of wrongdoing. Scores of sitting politicians, including Temer himself and several of his ministers, have been implicated. Temer denies wrongdoing. In one the largest demonstrations Friday, thousands of protesters gathered in front Rio de Janeiro's state assembly in the afternoon and were fighting pitched battles with police who tried to remove them. Police fired tear gas while protesters threw stones and lit small fires in the middle of streets. In Sao Paulo, police told downtown shopkeepers to close early, apparently out of concern that protesters might head there. Throughout the day, 21 people were arrested in Sao Paulo, according to military police. Underscoring the economic malaise, the IBGE statistics agency announced on Friday that unemployment had jumped to 13.7 percent in the first quarter of the year, up from 12 percent.

A produção industrial de autopeças de acordo com o Índice do IBGE, em fevereiro apresentou um crescimento de 12,5% na comparação com o mesmo mês de 2016. O resultado levou a um crescimento de 6,4% na fabricação de autopeças neste primeiro bimestre na comparação interanual. No acumulado dos últimos 12 meses, o segmento ainda carrega uma queda de 4,2%. No primeiro trimestre deste ano, a produção e as vendas de veículos novos e usados no País apresentaram um crescimento, portanto, a indústria de autopeças vem acompanhando o movimento das montadoras de modo geral, e do segmento de reposição. Todavia, pesa sobre o setor a concorrência com as importações. O fim da desoneração da folha de pagamento impacta o setor de autopeças acentuando a concorrência das autopeças nacionais em relação às importadas.

One of the main purposes of epidemiological studies is to estimate causal effects. Causal inference should be addressed by observational and experimental studies. A strong constraint for the interpretation of observational studies is the possible presence of unobserved confounders (hidden biases). An approach for assessing the possible effects of unobserved confounders may be drawn up through the use of a sensitivity analysis that determines how strong the effects of an unmeasured confounder should be to explain an apparent association, and which should be the characteristics of this confounder to exhibit such an effect. The purpose of this paper is to review and integrate two independent sensitivity analysis methods. The two methods are presented to assess the impact of an unmeasured confounder variable: one developed by Greenland under an epidemiological perspective, and the other developed from a statistical standpoint by Rosenbaum. By combining (or merging) epidemiological and statistical issues, this integration became a more complete and direct sensitivity analysis, encouraging its required diffusion and additional applications. As observational studies are more subject to biases and confounding than experimental settings, the consideration of epidemiological and statistical aspects in sensitivity analysis strengthens the causal inference.

An economic model including the labor resource and the process stage configuration is proposed to design X̄ charts allowing for all the design parameters to be varied in an adaptive way. A random shift size is considered during the economic design selection. The results obtained for a benchmark of 64 process stage scenarios show that the activities configuration and some process operating parameters influence the selection of the best control chart strategy; to model the random shift size, its exact distribution can be approximately fitted by a discrete distribution obtained from a relatively small sample of historical data. However, an accurate estimation of the inspection costs associated to the SPC activities is far from being achieved. An illustrative example shows the implementation of the proposed economic model in a real industrial case. © 2011 Elsevier B.V. All rights reserved.

This work analyzes the GompertzPareto distribution (GPD) of personal income, formed by the combination of the Gompertz curve, representing the overwhelming majority of the economically less favorable part of the population of a country, and the Pareto power law, which describes its tiny richest part. Equations for the Lorenz curve, Gini coefficient and the percentage share of the Gompertzian part relative to the total income are all written in this distribution. We show that only three parameters, determined by linear data fitting, are required for its complete characterization. Consistency checks are carried out using income data of Brazil from 1981 to 2007 and they lead to the conclusion that the GPD is consistent and provides a coherent and simple analytical tool to describe personal income distribution data. © 2010 Elsevier B.V.

We propose a model for the statistical design of a variable sample size chi-squared control chart (VSS χ2 control chart) for monitoring linear profiles. Performance measures of the proposed adaptive control chart are obtained through a Markov chain approach. Through a numerical example, which consists of a calibration application in a production process of semiconductors, the proposed chart is compared to the fixed parameter chi-squared control chart (FP χ2 chart) to monitor the intercept and slope of the linear profile. From this example, it is possible to assess the potential benefits provided by the proposed chart. Also, considering simultaneous shifts in the intercept, the slope, and the standard deviation, a sensitivity analysis of the proposed chart for monitoring linear profiles is presented. © 2015, Springer-Verlag London.

Recent bamboo collections from Brazil, and the study of specimens from several Brazilian herbaria revealed that the species described as Eremocaulon setosum, subtribe Guaduineae, in fact fits within the Arthrostylidiinae genus Aulonemia, based on floral and anatomical characters. Several characters found in this species, such as paniculate determinate synflorescences, solitary spikelets, an abaxial marginal green stripe on the foliage leaf blades, absence of stomata on the entire adaxial side of the leaf blade, and intercostal fibers in the mesophyll are typical features of the subtribe Arthrostylidiinae. The new combination Aulonemia setosa is here proposed, an epitype is designated, and a broader distributional range of this species is documented. © 2010 The New York Botanical Garden.

Arthrostylidiinae are one of the three subtribes of Neotropical woody bamboos and comprise 13 genera and over 160 described species. Recent phylogenetic analyses have demonstrated both the non-monophyly of Aulonemia Goudot and the sister relationship of Aulonemia ulei (Hack.) McClure to the monotypic Glaziophyton Franch., with which it forms a clade sister to the reminder of the subtribe. Based on these data and on morphological and anatomical characters, we present herein the new monotypic genus Cambajuva, as well as a new combination, to accommodate A. ulei. Morphological and anatomical descriptions are also provided, as well as a comparison with putatively related genera of the subtribe. © 2013 by the American Society of Plant Taxonomists.
