Vinicius Jr case opens wider racism debate in Spain
Insults aimed at Real Madrid soccer player Vinicius Jr have triggered a fierce debate about racism in sport and whether Spanish society has a problem with the issue.
Spanish police have arrested three people in connection with racist abuse directed at Vinicius Jr, who confronted fans of Valencia football club in the Mestalla stadium who he accused of directing monkey chants at him. After the match, the Brazilian international said the Spanish football league “belongs to racists”. […]

Discoveries of aquifers — underground earth formations that hold water — often create excitement around their ability to ease water scarcity in a region. The United States recently announced the discovery of five aquifers in Niger, one of Africa’s most water scarce countries, containing over 600 billion cubic metres of water. To put it into perspective, Egypt’s current water demand is 114 billion cubic metres of water per year.
These are welcome announcements. Due to a changing climate and the increasing demands of a growing population, many of Africa’s surface water resources — such as dams and rivers — are facing serious risks. They’re being overused and slowly decreasing.
Alternative water sources, like aquifers, need to be explored. They are highly prevalent across the African continent, but they’re not always going to help address water scarcity. For instance, early research findings deemed Kenya’s Turkana aquifer water unfit for use due to high salinity. It’s important to bear these challenges in mind so that expectations can be managed. It is also useful for planners and governments, as they need to think of other ways around the water scarcity problem.

INSTRUCTIONS: Read the following text to answer question.
TEXT
Blood sugar issues like type 2 diabetes and prediabetes have become incredibly common and are slated to impact billions in the decades to come. The well-known associations between these conditions and immune, kidney, cardiovascular as well as brain diseases make it more important that we better understand what’s controlling our blood sugar. It’s now been established that sleep may be one major regulator.
It’s been well established that sleep deprivation damages healthy blood sugar and insulin function, while getting good sleep may have the opposite effect. Yet the reasons why have remained less clear. In a paper just published by a team including sleep expert and author of Why We Sleep, Dr. Matthew Walker, researchers looked at associations between markers of sleep brainwaves and blood sugar markers the next day. After examining hundreds of people, they found that certain patterns of brain activity measured during deep sleep (non-REM) significantly predicted fasting blood sugar measurements the next day. The researchers concluded that their findings suggest a link between sleep and blood sugar regulation. They also draw attention to the significance of this result in the context of management of blood sugar issues like diabetes.

The expression to be slated in the sentence “Blood sugar issues like type 2 diabetes and prediabetes have become incredibly common and are slated to impact billions in the decades to come” means to happen in the future.

O Texto é um excerto de uma entrevista concedida pela pesquisadora Kate Crawford a propósito de um livro, de sua autoria, sobre a Inteligência Artificial. Ele será utilizado para a questão
Texto
Kate Crawford studies the social and political implications of artificial intelligence. She is a research professor of communication and science and technology studies at the University of Southern California and a senior principal researcher at Microsoft Research.
The Observer: You’ve written a book critical of AI but you work for a company that is among the leaders in its deployment. How do you square that circle?
Kate Crawford: I work in the research wing of Microsoft, which is a distinct organisation. Unusually, over its 30-year history, it has hired social scientists to look critically at how technologies are being built. My book did not go through any pre-publication review – Microsoft Research does not require that – and my lab leaders support asking hard questions, even if the answers involve a critical assessment of current technological practices.
The Observer: What’s the aim of the book?
Kate Crawford: We are commonly presented with this vision of AI that is abstract and immaterial. I wanted to show how AI is made in a wider sense – its natural resource costs, its labour processes, and its classificatory logics. My hope is that, by showing how AI systems work, we will have a more accurate account of the impacts, and it will invite more people into the conversation. These systems are being rolled out across a multitude of sectors without strong regulation, consent or democratic debate.
