Ao discutir o surgimento das Ciências Sociais, o sociólogo Florestan Fernandes desenvolve sua análise partindo
do princípio da multicausalidade. Assim, não é possível atribuirmos uma única causa que explique o surgimento
da sociologia no séc. XIX, mas uma combinação de vários fatores, que começam a se definir na transição da
idade média para a era moderna e que tornaram possíveis as condições para o surgimento dessa ciência. Dentre
os fatores a seguir, identifique os que se relacionam ao surgimento da sociologia e assinale a alternativa
correspondente:
O estágio inicial de um modelo epidemiológico, que mede o número de pessoas infectadas em uma população, é
descrito pela função I(t) = I02rt,em queI(t)representa o número de infectados da população, I0 > 0representa o
número inicial de infectados, r > representa a taxa de contágio e t é o tempo medido em dias desde o início da
epidemia. Com relação ao número de infectados, é correto afirmar:

Teaching methods keep changing with the times,................... the blackboard of the old days ........... electronic teaching today. Mr. Kam, physics instructor the Chinese University of Hong Kong, is one of those who has changed ......... the times.
Mr. Kam employs a two-pronged approach. First, he uses multimedia teaching materials during lectures. Second, he arranges internships for undergraduates. These can take the form of learning assistantships at the university or teaching assistantships at secondary schools, and also there’s always the odd science project at the Space Museum.
The initiatives have earned him the Faculty Exemplary Teaching Award 2020. A CUHK alumnus, he is grateful for the chance to teach at the university after earning his doctoral degree there. His teaching position actually represents the fulfillment of a dream, for the status of professors during his days as a university student was extremely high and he could meet them only during lectures.
After being a teacher for 10 years, Mr. Kam has found no apparent regression in the learning abilities of students, but he believes teachers should not just force knowledge on students - they have to pay careful attention to their needs too.
The multimedia materials that Mr. Kam uses to illustrate his area of interest includes animation and video clips. He encourages students to read popular astronomy magazines and share any note-worthy content they find. Mr. Kam also gets his undergraduates to help prepare students sitting for physics papers in public exams or to help out on research projects undertaken by meteorological officers at the observatory.
He also arranges for his undergraduates to teach students from other faculties during physics liberal studies classes through talks and star-gazing expeditions. Such responsibilities serve two greater purposes.
First, undergraduates become even more motivated to learn when they find out they have to guide other students. Second, physics students are, unlike arts students, not at their best when called upon to express themselves. Acting as assistants allows them to practice their skills and build up their self- confidence.
I asked Mr. Kam what he found most satisfying in teaching.
And the answer is obvious. It is the deep friendship he forms with students. Mr. Kam says many former students still come back to see him occasionally despite being busy parents. He draws considerable satisfaction from seeing his students grow into mature adults.
For Mr. Kam, the best teachers will never find extracurricular activity a burden because the good work that is done today plants the seed for future generations.

Claudine and Dismas have always struggled to make ends meet in Burundi. On their farm, they grow beans, maize, bananas and sorghum, which helps them financially since their harvest is profitable, and the lands fruitful. After her second pregnancy, Claudine became very ill, and much of the extras they had went to pay for traditional healers and medical doctors searching for answers to her sickness.
The birth of their second child, Valerie, with clubfoot added to the family’s tight financial situation. The condition was not even identified until about a month after Valerie was born when her grandmother was changing her. The grandmother recognized clubfoot because Claudine’s stepsister also had children born with the disability. People discouraged Claudine and Dismas from finding treatment because they felt Valerie’s feet resulted from the strange illness Claudine suffered during her pregnancy. Even if treatment was possible, neighbors reasoned the family would never be able to afford it.
Claudine and Dismas decided to put all their limited financial resources toward clubfoot treatment. Still, saving enough money for transportation to the first clinic visit took them a while. At the clinic, Hope Walks staff gave them the good news that treatment would be free for them.

Americans May Add Five Times More Plastic to the Oceans Than Thought
The United States is using more
plastic than ever, and waste exported for
recycling is often mishandled, according
to a new study.
The United States contribution
to coastal plastic pollution worldwide is
significantly larger than previously
thought, possibly by as much as five
times, according to a study published
Friday. The research, published in Science
Advances, is the sequel to a 2015 paper
by the same authors. Two factors
contributed to the sharp increase:
Americans are using more plastic than
ever and the current study included
pollution generated by United States
exports of plastic waste, while the earlier
one did not.
The United States, which does
not have sufficient infrastructure to
handle its recycling demands at home,
exports about half of its recyclable waste.
Of the total exported, about 88 percent
ends up in countries considered to have
inadequate waste management.
“When you consider how much
of our plastic waste isn’t actually
recyclable because it is low-value,
contaminated or difficult to process, it’s
not surprising that a lot of it ends up
polluting the environment,” said the
study’s lead author, Kara Lavender Law,
research professor of oceanography at
Sea Education Association, in a
statement.
The study estimates that in
2016, the United States contributed
between 1.1 and 2.2 million metric tons of
plastic waste to the oceans through a
combination of littering, dumping and
mismanaged exports. At a minimum,
that’s almost double the total estimated
waste in the team’s previous study. At the
high end, it would be a fivefold increase
over the earlier estimate.
Nicholas Mallos, a senior
director at the Ocean Conservancy and an
author of the study, said the upper
estimate would be equal to a pile of
plastic covering the area of the White
House Lawn and reaching as high as the
Empire State Building.
The ranges are wide partly
because “there’s no real standard for
being able to provide good quality data on
collection and disposal of waste in
general,” said Ted Siegler, a resource
economist at DSM Environmental
Solutions, a consulting firm, and an
author of the study. Mr. Siegler said the
researchers had evaluated waste-disposal
practices in countries around the world
and used their “best professional
judgment” to determine the lowest and
highest amounts of plastic waste likely to
escape into the environment. They settled
on a range of 25 percent to 75 percent.
Tony Walker, an associate
professor at the Dalhousie University
School for Resource and Environmental
Studies in Halifax, Nova Scotia, said that
analyzing waste data can amount to a
“data minefield” because there are no
data standards across municipalities.
Moreover, once plastic waste is shipped
overseas, he said, data is often not
recorded at all.
Nonetheless, Dr. Walker, who
was not involved in the study, said it
could offer a more accurate accounting of
plastic pollution than the previous study,
which likely underestimated the United
States’ contribution. “They’ve put their
best estimate, as accurate as they can be
with this data,” he said, and used ranges,
which underscores that the figures are
estimates.
Of the plastics that go into the
United States recycling system, about 9
percent of the country’s total plastic
waste, there is no guarantee that they’ll
be remade into new consumer goods. New
plastic is so inexpensive to manufacture
that only certain expensive, high-grade
plastics are profitable to recycle within the
United States, which is why roughly half
of the country’s plastic waste was shipped
abroad in 2016, the most recent year for
which data is available.
Since 2016, however, the
recycling landscape has changed. China
and many countries in Southeast Asia
have stopped accepting plastic waste
imports. And lower oil prices have further
reduced the market for recycled plastic.
“What the new study really underscores is
we have to get a handle on source
reduction at home,” Mr. Mallos said. “That
starts with eliminating unnecessary and
problematic single-use plastics.”
