Voices: The Pope's powerful message to Cubans

Rick Jervis, September 24, 2015 

SANTIAGO DE CUBA – I've always been fairly skeptical about how much power one man can exercise, even if that man commands the attention of 1.2 billion Roman Catholics.
    I understand that Pope John Paul II visited Poland in the 1970s and '80s and gave speeches so stirring that they helped launch the Solidarity opposition movement and lead to the collapse of communism in the country. And I know that popes throughout history have had influential moments.
    But, really, how much can one man and one microphone do? How literally do people take his message? These were the questions that kept my mind busy when I left for Cuba last week to cover Pope Francis' four-day trip. I was curious to see how much impact the words of this 78-year-old man can have on a population of 11 million.
    I'm becoming fairly familiar with Cuba. I've been to the island three times this year, five times overall, and grew up in southern Florida. My parents are Cubans who left the country in 1962. Cuba today continues to fascinate and dismay. It's a place of beauty and jolting contradictions. The re-establishment of relations between the U.S. and Cuban governments, begun last December, continue to stir excitement and hope in Cubans, and changes are trickling in.
    I followed Pope Francis from Havana to Santiago and heard him talk of reconciliation, love for mankind and the importance of family. I interviewed Cubans who glowed with the fervor of the faithful as they pledged their love for the Pope and promised to follow his message. But my question remained: What does all of this mean? How does it translate to actual change on the island?
    To help me sort through this, I visited Father Jorge Catasus, a popular parish priest here who helped welcome the Pope to the city. We sat in the cool, cavernous back room of his 18th-century church, safe from the 37-degree heat outside. Catasus said “don't focus on any grand political or social changes stemming from the papal visit". The most important changes, he said, come from within. That's what Pope Francis offered as a first step, and that's what Cubans across the island, in chants, cheers and tearful acceptance, agreed to abide by.
    “The lives of men are decided in their hearts", Catasus told me. “That's where we'll see the change". This may not be 1980s Poland, and Solidarity may still not be anywhere in sight. But first things first. A change of heart can often lead to a world of good.
Adapted from <http://www.usatoday.com/>
A
he wondered about the power of the words to cause social changes.
B
Cuba does not have as many Catholics as Poland had in the 1970s.
C
this Pope is not as powerful as John Paul II.
D
Cubans are not so easily convinced compared to other nationalities.
E
Popes have not been influential in different historical moments.

Forget Texting While Driving: AT&T Survey reveals drivers do a lot more with their smartphones
By Menchie Mendoza, Tech Times | May 20, 10:10 AM 


    Drivers who continue to use their smartphones while driving are not only distracted when they call and text. Apart from calling and texting, drivers are also browsing the Internet, tweeting, video chatting, taking selfies and sending email with their devices, according to a study by AT&T.
    The research was conducted as part of the carrier's "It Can Wait" campaign launched in 2010. It hopes to increase awareness of the dangers posed by using smartphones while one is behind the wheel. The study polled 2,067 U.S. residents ages 16-65 who use their smartphone and drive once or more per day.
    Seventy percent of those surveyed admit they use their smartphones for a number of activities while they are driving: 61 percent say they text and 33 percent send email while they are behind the wheel. Posting or interacting on social media is also one of the most common activities that drivers engage in. Using Facebook ranks first on the list, with 27 percent of drivers logging in while driving. Other social media channels that keep drivers "multitasking" include Instagram and Twitter (14 percent) and Snapchat (11 percent).
    The results also show that there is a deeper problem involved when people use social media while driving. Among those surveyed, 22 percent blame their addiction to social media.
    Other revelations show 62 percent keep their smartphones within easy reach, and that 30 percent of those who post to Twitter while driving do it "all the time". Drivers also don't seem to run out of other activities using their smartphones since most apps are now easily accessed with just a simple tap. Because of this, 28 percent of drivers browse the web; 17 percent take selfies (or groupies); and 10 percent video chat.
    "One in 10 say they do video chat while driving", said Lori Lee, AT&T's senior VP for global marketing. "I don't even have words for that". AT&T plans to expand the "It Can Wait" campaign in order to add more focus on the topic of texting while driving by including other driving distractions that result from using the smartphones. "When we launched 'It Can Wait' five years ago, we pleaded with people to realize that no text is worth a life", said Lee. "The same applies to other smartphone activities that people are doing while driving. For the sake of you and those around you, please keep your eyes on the road, not on your phone". AT&T will also launch a nationwide virtual reality tour in summer in order to spread the word that driving and using a smartphone don't and will never mix.

Um estudo da Universidade Federal de Minas Gerais mostra que é possível reduzir muito os arrotos das 211 milhões de cabeças do rebanho brasileiro. Com melhor pasto e suplementação alimentar, o gado engordaria mais e mais rápido e passaria menos tempo arrotando.

Fonte: Folha de S. Paulo, 29 de agosto de 2015.

A redução da quantidade de arrotos pode ajudar a controlar o aquecimento do planeta porque diminui a emissão de: 

A

Desastres em usinas nucleares, como os ocorridos em Chernobyl (1986) e Fukushima (2011), geram preocupação devido às grandes quantidades de material radioativo lançadas no ambiente. A radiação produz mutações, tendo efeitos sobre a hereditariedade. No caso das células do sistema reprodutor masculino, a duração dos efeitos depende do estágio da espermatogênese afetado pela radiação, podendo haver menor ou maior chance de a mutação causar efeitos transgeracionais (aparecer nas gerações futuras). O efeito da radiação será mais duradouro e será mais provável a observação de efeitos transgeracionais se a mutação ocorrer: 

A
nos espermatozoides.

Extinção primária é o desaparecimento de uma espécie decorrente de impactos ambientais causados por ações humanas. A extinção primária de uma espécie pode ter como consequência a extinção de outra espécie. Nesse caso, fala-se em extinção secundária. A probabilidade de ocorrer extinção secundária vai depender de diversos fatores, entre os quais as características da espécie em risco e da sua interação com a primeira espécie extinta. Assinale a alternativa que reúne características que levam a uma maior probabilidade de ocorrer extinção secundária:

A
Grau de especialização da interação entre a espécie extinta e a espécie em risco - Baixo

Resposta evolutiva da espécie em risco - Lenta

Grau de dependência entre a espécie extinta e a espécie em risco - Baixo
B
Grau de especialização da interação entre a espécie extinta e a espécie em risco - Alto

Resposta evolutiva da espécie em risco - Lenta

Grau de dependência entre a espécie extinta e a espécie em risco - Alto
C
Grau de especialização da interação entre a espécie extinta e a espécie em risco - Baixo

Resposta evolutiva da espécie em risco - Rápida

Grau de dependência entre a espécie extinta e a espécie em risco - Baixo
D

As mudanças climáticas têm desencadeado processos de aclimatação em comunidades de plantas. Em comunidades não aclimatadas, quando não há outros fatores limitantes, a taxa dos processos biológicos (por exemplo, fotossíntese e respiração) tipicamente dobra a cada aumento de 10 ºC na temperatura ambiente. Quando há aclimatação, ela pode ser de dois tipos: Tipo I – Ocorre uma redução da sensibilidade à temperatura, com diminuição da atividade em temperaturas maiores, mas sem alterações em temperaturas menores. Tipo II – Há um decréscimo da atividade em todas as temperaturas, mas a taxa dobra a cada aumento de 10 ºC na temperatura da mesma forma que nas plantas não aclimatadas.

Assinale a alternativa que traz a figura que representa corretamente a relação entre temperatura e taxa dos processos em plantas aclimatadas e não aclimatadas.
