Inglês
"No notável ensaio A Review of Skinner's Verbal
Behavior , publicado em 1959, X argumenta(m) que
a aquisição de uma língua não pode ser explicada
simplesmente como resposta a estímulos, já que as
crianças produzem palavras e sentenças que não
constam em seu input linguístico, ou seja, que não
pronunciadas por seus pais ou pelas pessoas de seu
convívio. Dessa forma, o ser humano seria dotado de
uma faculdade específica - a faculdade da linguagem
-, situada na estrutura mente/cérebro, que possibilita
a qualquer ser humano desenvolver linguagem,
desde que exposto a um input linguístico. Essa
faculdade é inata, hereditária, inerente ao seu
humano e, também, o que o distingue dos demais
seres vivos. Com a instauração da Y e o
desenvolvimento de pesquisas em aquisição da
linguagem, foram aprimorados os métodos de
pesquisa e coleta de dados, e os estudos
longitudinais, terceiro e atual momento dos estudos
sobre aquisição da linguagem, passaram a ser os
eleitos, já que, por meio desse tipo de pesquisa, é
possível acompanhar o trajeto que a criança percorre
até atingir o alvo - sua língua materna." Fonte

Consider the text below.

'Let's drop the goo-goo routine, you can't be as dumb as you look', the studio head known as Mr R (an avatar for 20th Century Fox boss Darryl F Zanuck) tells her just before he sexually assaults her. However there is, at least, an element of bratty joyfulness to this Marilyn as she enjoys her success, and the film ends without putting her (and us) through her sorrowful demise."

IT HELP DESK
Working the IT help desk can be a great entry-level job.
As a help desk professional, your core responsibilities are to
provide technical help and support; that could mean setting
up and repairing computers or responding to a customer’s
question about how to use their computer, as well as
performing routine maintenance of a company’s computer
networks and internet systems or teaching staff how to use
new technologies. The job requires deep computer knowledge
and good technical and interpersonal skills. But what if you
want more? Additional credentials and advanced degrees can
help you move beyond the IT help desk. Here are three career
paths to consider.
(i) Cloud and systems administrator – Network and
systems administration is a natural next step from the IT
help desk. Organizations need reliable computer networks,
so there’s great demand for skilled professionals who can
manage, administer, and protect computer systems. (ii)
Network ops and security expert - Cybersecurity is a top-of-mind concern in every sector and industry. IT professionals
with expert training in network operations and security
systems are in high demand. (iii) IT manager – Yes, you will
need plenty of experience, credentials, and certifications; still,
you can get to a managerial or executive-level position from
the IT help desk. It can be tough to see the top through all
those steps of the stair, but the top is closer than you think.
Software development, computer network architecture,
and computer programming are other possible professions
those working on the IT help desk or in other entry-level
IT positions can pursue. In today’s ever-changing job
marketplace, there’s no one career pathway.

Mining trucks are monstrous machines that guzzle fuel
at a scarcely believable rate. Weighing 220 tonnes, they can
get through 134 litres of diesel every hour. Little wonder then
that mining companies are focusing their attention on these
vehicles as the first step to reducing their carbon footprint.
Anglo American, in collaboration with several partners, is
retrofitting a mining haul truck with hydrogen power technology.
A first of its kind, the monster mining vehicle is being piloted
in Limpopo, South Africa, at the firm’s Mogalakwena platinum
mine. Due to be launched early 2022, the truck will be hybrid,
with a hydrogen fuel cell providing roughly half of the power
and a battery pack the other half.
Instead of having a tank of diesel that powers the motor,
hydrogen enters the fuel cell and mixes with oxygen to create
water in a chemical reaction catalysed by platinum, which
generates the electricity needed to power the motors that
drive the wheels. By rolling out this technology across its
global truck fleet, Anglo American says it will be “taking the
equivalent of half a million diesel cars ‘off the road”.
The construction sector, which includes mining, accounted
for 39% of energy-related CO2
emissions in 2017, according
to Davide Sabbadin, from the European Environmental
Bureau. He says the sector will need to reduce its energy
consumption by a third if it hopes to be compatible with the
Paris Agreement. “While electric-powered vehicles, generally
speaking, are less damaging to the environment than internal
combustion engines on a life cycle analysis, this does not
mean that they are green,” he says. It all hinges on how the
hydrogen is produced. Some hydrogen is created using fossil
fuels, which of course means there are substantial emissions
as a result. “We should refrain from presenting hydrogen as a
technological solution to all problems… all forms of hydrogen
come at an environmental cost – water use, impacts on
nature,” says Mr Sabbadin.

João loved Teresa who loved Raimundo
who loved Maria who loved Joaquim who loved Lili
who didn’t love anyone.
João went to the United States, Teresa to a convent,
Raimundo died in an accident, Maria became a spinster,
Joaquim committed suicide, and Lili married J. Pinto Fernandes,
who had nothing to do with the story.
(Carlos Drummond de Andrade translated by
Richard Zenith in “Multitudinous Heart”
