The news from Brazil will get worse before it gets better.The arrest of the billionaire banker Andre Esteves suggests room for further nasty surprises from the Petrobras corruption investigation. Brazils roughly $2 trillion economy, Latin Americas biggest, is tanking. President Dilma Rousseff could be impeached. But feisty independent courts and stronger institutions point to a brighter future.The arrest on Wednesday of Mr. Esteves and Delcidio do Amaral, the ruling Workers Party leader in the Brazilian Senate, is the latest event in a huge investigation into bribes and kickbacks at the state oil giant Petroleo Brasileiro. It has rippled through the economy, affecting construction and power companies and even threatening to tarnish the Olympic Games in Rio de Janeiro. Fiercely independent judges are spearheading the inquiry, and Ms. Rousseff is in no position to try to influence them. Some 50 politicians are being investigated for bribery.The president has not been implicated, though she was chairwoman of the Petrobras board when much of the supposed improbity occurred. But she is hugely unpopular, blamed for sending the economy into its worst recession in 25 years and the austerity she espouses to fix it. Demonstrators have called for her impeachment.Brazils institutions have been growing stronger since democracy was restored in the 1980s, however, and can act as a bulwark against the populism that Ms. Rousseff has compared to coup-mongering. If she were impeached, it would probably be for questionable government accounting practices rather than incompetence and would only happen after a long process in Congress. She could also be in trouble if the Petrobras investigation finds illicit contributions to her 2014 re-election campaign.Plea bargains and other legal measures have made it easier to investigate companies since a huge vote-buying scandal known as the mensalao broke a decade ago. Though the court system has pockets of corruption and bogs down in bureaucracy, a well-functioning judiciary can offer more security for investors and eventually help the economy recover.The nation stands out from regional laggards like Venezuela, where the Bolivarian revolution of Hugo Chavez and his hapless successor, Nicolas Maduro, has seriously compromised the independence of government institutions. Facing crises of their own, such countries would do well to watch for the silver lining in Brazils: the rule of law. Fenomeno teatral: texto e espetaculoPode-se considerar a teatralidade algo intrinseco ao ser humano na medida em que oteatro tem origem em rituais como dancas tribais, ritos religiosos ou cerimonias publicas ou ainda na tendencia humana, particularmente infantil, deexperimentar o mundo por meio do jogo, do ludico. Aristoteles (1993, p. 27; 1448b 5-9)adverte naPoetica que a imitacao - que nao deixa de ser uma forma de teatralidade, de percepcao da vida socialcomo representacao e aprendizado -e natural ao ser humano e fonte de prazer.Contemporaneamente, vemos a teatralidade ocupar muitas dimensoes de nossa vida:os shows musicais de hoje sao verdadeiras mega-producoes que incluem danca,iluminacao, encenacao, pirotecnia, etc;os ritos nas igrejas, nos mais diferentes credos,retomam os efeitos teatrais remotamente utilizados na Idade Media; o teatro derua tem sido forte instrumento de informacao e/ ou conscientizacao social e politica; a publicidade tem se
