[…] According to the National Institute for Space Research, the number of fires detected in Brazil so far this year is 84 percent higher than in the comparable period last year; more than half of those are in the Amazon region. More than 1,300 new fires were added over the course of just two days this week. Satellites have captured images of the smoke from the flames sweeping across several Brazilian states. In São Paulo, where I live, dark clouds blackened the sun on Monday, turning day into night. The city is thousands of miles away from the Amazon. Meteorologists scrambled to explain what had happened, but many suspect that the culprit was low-lying clouds from a cold front combining with smoke. […]

Hundreds of people gathered at the world’s most famous zebra crossing on August to mark the 50th anniversary of the day The Beatles were photographed on it, creating one of the best-known album covers in music history and an image
imitated by countless fans ever since.
The picture of John Lennon, Paul McCartney, George Harrison and Ringo Starr striding over the pedestrian crossing on Abbey Road was taken outside the EMI Recording Studios where they made the 1969 album of the same name. The picture shows Lennon in a white suit leading the group across the road. Starr wears a black suit while McCartney is barefoot
out of step and holding a cigarette. Harrison is in blue denim. A Volkswagen Beetle is parked in the background.
Abbey Road, which was voted the best Beatles’ album by readers of Rolling Stone in 2009, was the only one of the group’s original British albums to show neither the band’s name nor a title on the cover.
The album was the last to be recorded by all four members of the band together, and it had tracks written by each of them. Less than a year after Abbey Road was released, rock music’s best-selling band had split up, ending a decade-long musical revolution that transformed the 1960s and laid the foundations of modern popular culture. The studios, which were later renamed Abbey Road, and the zebra crossing were granted protected status by the government in 2010.

What happened at Pearl Harbor?

On the morning of 7 December 1941, at 7.55am local time, 183 aircraft of the Imperial Japanese Navy attacked the United States Naval base at Pearl Harbor on the island of Oahu, Hawaii.

About seven years ago, three researchers at the University of Toronto built a system that could analyze thousands of photos and teach itself to recognize everyday objects, like dogs, cars and flowers. The system was so effective that Google bought the tiny start-up these researchers were only just getting off the ground. And soon, their system sparked a technological revolution. Suddenly, machines could “see” in a way that was not possible in the past.

This made it easier for a smartphone app to search your personal photos and find the images you were looking for. It accelerated the progress of driverless cars and other robotics. And it improved the accuracy of facial recognition services, for social networks like Facebook and for the country’s law enforcement agencies. But soon, researchers noticed that these facial recognition services were less accurate when used with women and people of color. Activists raised concerns over how companies were collecting the huge amounts of data needed to train these kinds of systems. Others worried these systems would eventually lead to mass surveillance or autonomous weapons.

Analise as afirmações de I a IV em destaque.

I. Ativistas manifestaram preocupação em relação à forma como as empresas estavam coletando enormes quantidades de dados para treinar sistemas de reconhecimento.

II. A Universidade de Toronto construiu um sistema ético de Inteligência Artificial para reconhecimento de imagens.

III. Uma das preocupações de ativistas era a possibilidade de tais sistemas conduzirem a vigilância em massa ou armamento autônomo.

IV. Empresas privadas de tecnologia, como Google, e redes digitais, como Facebook, junto com algumas agências governamentais, chegaram a um consenso quanto a uma ética da Inteligência Artificial.

V. Algumas leis foram desenvolvidas por alguns grupos específicos de pessoas para decidir sobre o futuro da Inteligência Artificial.

What does the word nationalist mean? (Part I)

The dictionary's definition of the word seems innocent enough: a person devoted to nationalism (the devotion and loyalty to one's own country). But make no mistake about it. Nationalist is a loaded and controversial term.

It dates back to the 17th century and rose into prominence during the uprisings in the 18th century that produced the American and French revolutions. But the word attained more of a negative connotation during the 20th century as it become associated with the nationalism movements in Europe that helped lead to World War I and World War II. Today the word is often associated with the far-right, racist ideologies of white nationalists.

Nationalism has been on the rise worldwide, as evidenced by the success of nationalist political parties in Europe. And it had a double bang in 2016, as it powered Brexit in the UK and the election of Trump as US President. Steve Bannon, Trump's former top strategist, said Trump used an "economic nationalist agenda" to win.
