(Mackenzie - 2016) Brazil Plans to Implement a Control Center on Border with Argentina and Paraguay Folha Online 03/20/2015 Renata Agostini From So Paulo Mariana Carneiro From Buenos Aires The Brazilian government started negotiations with Argentina to implement a Center of Integrated Command and Control in the Triple Border which unites the two countries and Paraguay as a way to intensify anti-smuggling efforts in the area. The information was given on Thursday (19) by the Minister of Justice Jos Eduardo Cardozo, at a forum held by Folha in So Paulo, entitled Smuggling in Brazil. The idea is to bring the police forces of the three countries which could draw together intelligence and enforcement operations. The neighbors could help each other also with commercial information and immigration in the region. Even if we put a man every 50 feet along the border, it would not be enough supervision. We need intelligence, the minister said. He said that border control is one of the main problems faced by Brazil in regards to public safety, and the solution would come from integrated actions combined with the use of technology. According to the Brazilian proposal, Paraguay would be exempt from the project cost, which would be funded by Brazil and Argentina, the minister said. The experience derived from the Integrated Centers erected in the 12 host cities for the World Cup was considered successful and inspired the idea of a unified initiative between the three countries. The region of the Triple Border, where the Brazilian city of Foz do Iguau is located, is a major entry point for smuggled goods in the country. Most come from Paraguay.

(MACKENZIE 2016) Se precisamos estar em constante contato com os outros, evidente que a comunicao essencial para a vida humana e a organizao social. Tambm bvio que, desde o comeo de nossa existncia, participamos do complexo processo de adquirir regras de comunicao e p-las em prtica. Na maioria das vezes, no discutimos os cdigos e os modos de us-los; simplesmente nos comunicamos por meio deles. Como afirmamos, isso acontece porque somos eminentemente sociais, incapazes de viver isolados. Alis, mesmo solitrios, estabelecemos um modo de comunicao a que a psicologia se refere como intrapessoal, quando nos questionamos internamente, a partir de nossos sentimentos, nossas dvidas, nossas motivaes interiores. Paralelamente, estamos em constante comunicao interpessoal, aquela que se d entre duas pessoas, ou grupal, que acontece entre uma pessoa e um grupo, ou viceversa, alm de recebermos os apelos da comunicao de massa, que se concretiza pelos meios tecnolgicos, como o rdio, o jornal, a televiso, entre outros, acionados por jornalistas e publicitrios, que geram e difundem informaes e anncios. Como fenmeno social, a comunicao d-se por intermdio de algum tipo de linguagem que, como vimos, se altera de acordo com o uso que as pessoas fazem dela. Verbais ou no verbais, criamos sinais que tm significado especial para o grupo humano do qual fazemos parte.

(Mackenzie - 2016) Science Without Borders Program to be Suspended 09/03/2015 - 09H02 VALDO CRUZ FLVIA FOREQUE Owing to lack of funds, the Planalto Palace has decided to suspend the offer of new scholarships as part of the program Science Without Borders for next year. As Folha has learnt, the budget defined by the governments economic team for next year, a total of R$ 2,1billion (USD $559million), is only enough to cover students who are already living abroad on the program. The Coordination of Improvement of Higher Education Students (CAPES, in its Portuguese acronym) said that the designated resources would be used to pay for 13.330scholarships amongst undergraduates and postgraduates in 2016, under its supervision. The National Council of Scientific and Technological Development (CNPQ), another government agency that encourages research, will be allocated resources for another 22.610scholarships. In total, both institutions will send 14.050undergraduates abroad in the second semester of this year. This group of students enters the program under last years selection process. Undergraduates account for the majority of those enrolled in the program, with 79.5%of the scholarships granted. Advisors to President Rousseff have admitted that the government was considering an even harsher cut to the program, but the idea was rejected owing to the likely negative effects it would produce. The cut for Science Without Borders next year is 40.3%from last years budget of R$ 3.5billion (USD $931million). Cutting just one percentage point more would mean disrupting the studies of those who have already been selected and left for university abroad. Launched in July 2011, the program has become one of President Rousseffs flagship policies. After the creation of 101,000places by last year, the promise for her second term was to create another 100,000. The high value of the dollar, however, has drastically increased the cost of program. The program pays foreign universities for the tuition of Brazilian students, as well as providing maintenance grants to the students themselves. While in July 2011 the dollar was worth R$ 1.55now the exchange rate is close to R$ 3.70. There is currently no date defined for the call of new applications to the program. Last year, the selection process began in August. The current expectation is that if the government allocates more funds for the program next year, the main focus will be postgraduates. Questioned on this, Capes would not comment. The agency said, All the Ministry of Education programs will be maintained in 2016. The Ministry is conducting a detailed analysis of the budget in order to determine the scope of the programs for next year, it said in a statement. PRONATEC If Science Without Borders is suspended in 2016, another federal education program will be significantly expanded next year, according to the budget provisions. In 2016, the government is expected to offer five million places on technical courses and on the National Program of Access to Technical Education and Employment (PRONATEC), both for those enrolling in the program as well as those continuing their training. This year, thanks to budget cuts, the numbers of offered places on the program fell to nearly a million, 66.6%less than the three million in 2014. Added to the cost of covering those already enrolled, the total cost of the program in 2015 is R$ 4billion (USD $1.1billion). After hitting its target of enrolling eight million students, the governments aim was to enroll 12 million new students in its second term. If 2016s targets are reached, the government will achieve exactly 50% of the target in the first two years of its second term.

(Mackenzie - 2016) The following text refers to question(s) below. Life With Stephen Hawking In 2013, the remarkable life of cosmologist Stephen Hawking was the subject of a documentary called, quite simply, Hawking. Now it is the subject of a feature film. Its called The Theory of Everything and its directed by James Marsh. The film is based on the memoir of Hawkings first wife, Jane Hawking, who met her husband at Cambridge in the 1960s. In the film Jane Hawking is played by Felicity Jones, who says: FELICITY: I think there was an immediate sexual attraction, but at the same time there was a meeting of minds, and I think they challenged each other as well, I think there was a competitiveness between them, which often, when two people who are quite different and I think it was that difference between them that brought them together. But the young couple hadnt been together very long before Stephen Hawking was diagnosed as having Motor Neurone Disease, also known as ALS, or Amyotrophic Lateral Sclerosis. In The Theory of Everything Stephen Hawking is played by Eddie Redmayne, who talked about the physicists famous voice machine: EDDIE: His relationship with the voice; I mean, the voice itself. It had never occurred to me when I got this part, Why has Stephen Hawking got an American voice? And the answer was, that was the first technology that came, and because his voice then became so related to or his icon became so related to that voice, hes never wanted to change it because thats what we know as his new identity, and vocal identity, and my God is identity important! Jane Hawking nursed her husband for many years and, as Felicity Jones says, they managed to maintain a sense of humour. FELICITY: Thats so important, and thats what weve wanted in telling this story is how both Jane and Stephen are absolutely hilarious, they have a very dry sense of humour, a very English sense of humour, and I think thats partly what enabled them to cope with such difficult circumstances was that theres always a witticism about it, and meeting Stephen, he was incredibly witty and insightful ... and a very dry sense of humour. Stephen and Jane Hawking divorced in the 1990s and Jane subsequently published her memoir as Music to the Stars. It was later revised and republished as Travelling to Infinity. Both titles reflect Stephen Hawkings status as the worlds most important living scientist. As Eddie Redmayne says, this is a remarkable achievement, under the circumstances. EDDIE: The astounding thing is that Stephen Hawking was given two years to live aged 21, and hes now 71, 72. I mean, its against all odds , and its a staggering thing, and whether it is to do with his passion, his drive, his outlook on life, his humour, the specific strain of what the disease is, no one knows, but its a staggering thing, and he is a great icon of hope. www.speakup.com The alternative that contains only adjectives from the text is
