No modo de produção capitalista, o Estado é um instrumento de dominação de uma classe social sobre toda a sociedade. A classe dominante detém o poder do Estado, em outros termos e, em consequência disso, o regime político é definido por esta classe social na direção do poder estatal. Assim sendo, em uma sociedade capitalista, um regime democrático com supostas instituições livres, leis e normas imparciais é meramente uma fachada que encobre o domínio social, cultural e político da classe dominante. O Estado, em síntese, é um aparelho ideológico de governança da classe dominante que dirige um regime social e político cheio de antagonismos de uma estrutura social contraditória.Considerando o raciocínio apresentado no enunciado acima, assinale a afirmação verdadeira. - Linguagens

Minority ethnic Britons face ‘shocking’ job discrimination

A study by experts based at the Centre for Social Investigation at Nuffield College, University of Oxford, found applicants from minority ethnic backgrounds had to send 80% more applications to get a positive response from an employer than a white person of British origin.
A linked study by the same researchers, comparing their results with similar field experiments dating back to 1969, found discrimination against black Britons and those of south Asian origin – particularly Pakistanis – unchanged over almost 50 years.
The research, part of a larger cross-national project funded by the European Union and shared exclusively with the Guardian before its official launch, prompted concerns that race relations legislation had failed.
It echoes findings published as part of the Guardian’s Bias in Britain series that people from minority ethnic backgrounds face discrimination when seeking a room to rent. In a snapshot survey of online flatshare ads the Guardian found that an applicant called Muhammad was significantly less likely to receive a positive response than an applicant called David.
Prof Anthony Heath, co-author and emeritus fellow of Nuffield College, said: “The absence of any real decline in discrimination against black British and people of Pakistani background is a disturbing finding, which calls into question the effectiveness of previous policies. Ethnic inequality remains a burning injustice and there needs to be a radical rethink about how to tackle it.”
Dr Zubaida Haque, the deputy director of the race equality thinktank Runnymede, described the findings as shocking. They demonstrated that “it’s not just covert racism or unconscious bias that we need to worry about; it’s overt and conscious racism, where applicants are getting shortlisted on the basis of their ethnicity and/or name”, she said.
“It’s clear that race relations legislation is not sufficient to hold employers to account. There are no real consequences for employers of racially discriminating in subtle ways, but for BME* applicants or employees it means higher unemployment, lower wages, poorer conditions and less security in work and life.”

Para Ribeiro (2006), a história da formação e o sentido da sociedade brasileira explicam a razão por que o Brasil “não deu certo”. Ele quis dizer, em resumo, que o Brasil não conseguiu atingir, de modo satisfatório, justiça social ao longo de sua história. As razões históricas para isto é que duas de suas matrizes formadoras, a Tupi e a Afro, foram quase que, respectivamente, “desindianizada” e “desafricanizada” no processo da empresa colonial. De outra forma, os índios e os negros africanos, além de quase serem extintos fisicamente, foram “desculturalizados” de suas diversas culturas originais devido à escravidão e excluídos da justa distribuição econômica dos bens socialmente produzidos. Ao lado da escravidão sofrida por essas matrizes originais esteve a base econômica colonial de monocultura latifundiária geradora de concentração de terras na posse de poucos, o que ajudou a gestar uma sociedade desigual, cheia de disparidades, contradições e antagonismos que subsiste sob o rótulo de “povo brasileiro”.RIBEIRO, Darcy.

The word ‘viral’ has lost its meaning
The nature of virality has shifted radically over the past decade as the internet has fractured into uncounted disparate algorithms, platforms, and niche communities. The volume of content being churned out every day has skyrocketed, the life cycle of each piece of media has grown shorter and social media platforms continue to inflate public metrics, devaluing previously impressive online stats.
All of these factors have rendered the term “viral” nearly meaningless, say experts, and have led to a condition we’ll call “viralflation.” The term speaks to the diminished meaning of virality. If everything is labeled viral, then is nothing viral?
“Back in the day, 1 million views was the thing,” said Marcus Stringer, a partner manager at Social Blade, a social media analytics platform. “That meant you’d gone viral, and you’d get picked up by news agencies around the world. Now, tens of millions of views is the norm for top YouTube channels. Soon, 20 million views will eventually become the norm.”
“Because the concept of virality has been so watered down, truly viral pieces of content must reach hundreds of millions of people at a scale that’s increasingly unattainable for anyone but MrBeast,” said Lara Cohen, vice president of partners and business development at Linktree, a platform that allows creators to aggregate links to their social media profiles on one page. MrBeast is the internet name of Jimmy Donaldson, YouTube’s most watched creator.
A decade and a half ago, there was a clear delineation between viral content and the vast majority of media that users would encounter every day. The internet was smaller, and most sharing was manual (people emailing and messaging links to each other) or via early internet aggregators such as sites like Digg and StumbleUpon.
Viral content emerged slowly, so the life span of a viral video was long. Some content remained viral for up to a year, worming its way through the internet as it gained traction. When social media platforms began to switch to algorithmic feeds optimized for engagement in the mid 2010s, the viral content cycle accelerated, experts said. Brands began recognizing the power of virality and started to attempt to manufacture it. Content creators joined engagement groups where they’d reshare each other’s content in attempts to force virality.
Platforms themselves also began to realize the power of virality and sought to generate it, or at least generate the appearance of it. This was the beginning of the era of viralflation. Facebook helped lower the industry-wide threshold for what counted as a video view, and began inflating view counts on various Facebook videos in an effort to make them appear more viral than they were.
Then TikTok broke into the mainstream in 2020, lowering the bar even further for what counted as a “view.” While a view on Facebook counts after three seconds of watch time, a view on TikTok is simply an impression, meaning the video was served to a user for at least a fraction of a second on screen. According to the company, TikTok also counts each loop of the video as a view, allowing videos to rake in massive view counts.
“The speed at which we cycle through trends and sort of moments of virality on the internet is faster now largely because of TikTok,” Cohen said. This has created an arms race among tech platforms to see which could inflate metrics the most. There’s been an incentive to have these numbers look bigger because they look better to advertisers, so there’s a financial incentive to cause this viral inflation.
A new class of content creators also has raised the bar for what’s considered viral. “When MrBeast started to explode, things really started to change in the landscape,” Stringer said. “People didn’t consider [earlier metrics of virality] viral anymore, because he’s getting multi millions of views per video.”
Coco Mocoe, a trend forecaster in Los Angeles, said that along with these shifts, users are also consuming a higher total amount of content online per day, especially members of Generation Z, those born between 1998 and 2012. They are more likely to consume all forms of media through the internet and social platforms, rather than via newspapers or TV. And, much of that content is short form and less than 60 seconds long. “The main reason there are bigger numbers now is because people are consuming so much more content in a given sitting,” she added.
This has made virality more ephemeral. “There’s not that same… permanence,” Mocoe said. “If you’re watching 50 videos with 1 million views, you’re less likely to remember one as opposed to a decade ago, when you might only watch five videos a day, and just one would have 1 million views.” For the average consumer, viralflation has made it increasingly difficult to tell what is and isn’t actually viral. Because we no longer have any shared sense of virality, it makes it easier for people who don’t understand the mechanics of the internet to fall for fake viral trends.

Dessa forma criou-se os poderes Executivo, Legislativo e Judiciário passando cada um a ter sua função específica e independente não desmerecendo as demais, já que nenhum poder se sobressai aos demais.Fonte: Adaptado de http://www.mundoeducacao.com/politica/.Considerando as funções principais dos três poderes associe corretamente a COLUNA A com A COLUNA B, indicando qual a função de cada Poder.

A new class of content creators also has raised the bar for what’s considered viral. “When MrBeast started to explode, things really started to change in the landscape,” Stringer said. “People didn’t consider [earlier metrics of virality] viral anymore, because he’s getting multi millions of views per video.”
Coco Mocoe, a trend forecaster in Los Angeles, said that along with these shifts, users are also consuming a higher total amount of content online per day, especially members of Generation Z, those born between 1998 and 2012. They are more likely to consume all forms of media through the internet and social platforms, rather than via newspapers or TV. And, much of that content is short form and less than 60 seconds long. “The main reason there are bigger numbers now is because people are consuming so much more content in a given sitting,” she added.
This has made virality more ephemeral. “There’s not that same… permanence,” Mocoe said. “If you’re watching 50 videos with 1 million views, you’re less likely to remember one as opposed to a decade ago, when you might only watch five videos a day, and just one would have 1 million views.” For the average consumer, viralflation has made it increasingly difficult to tell what is and isn’t actually viral. Because we no longer have any shared sense of virality, it makes it easier for people who don’t understand the mechanics of the internet to fall for fake viral trends.
