The World Might Be Running Low on Americans


    The world has been stricken by scarcity. Our post-pandemic pantry has run bare of gasoline, lumber, microchips, chicken wings, ketchup packets, cat food, used cars and Chickfil-A sauce. Like the Great Toilet Paper Scare of 2020, though, many of these shortages are the consequence of near-term, Covid-related disruptions. Soon enough there will again be a chicken wing in every pot and more than enough condiments to go with it.


    But there is one recently announced potential shortage that should give Americans great reason for concern. It is a shortfall that the nation has rarely had to face, and nobody quite knows how things will work when we begin to run out.


    I speak, of course, of all of us: The world may be running low on Americans — most crucially, tomorrow’s working-age, childbearing, idea-generating, community-building young Americans. Late last month, the Census Bureau released the first results from its 2020 count, and the numbers confirmed what demographers have been warning of for years: The United States is undergoing “demographic stagnation,” transitioning from a relatively fast-growing country of young people to a slow-growing, older nation.


    Many Americans might consider slow growth a blessing. Your city could already be packed to the gills, the roads clogged with traffic and housing prices shooting through the roof. Why do we need more folks? And, anyway, aren’t we supposed to be conserving resources on a planet whose climate is changing? Yet demographic stagnation could bring its own high costs, among them a steady reduction in dynamism, productivity and a slowdown in national and individual prosperity, even a diminishment of global power.


    And there is no real reason we have to endure such a transition, not even an environmental one. Even if your own city is packed like tinned fish, the U.S. overall can accommodate millions more people. Most of the counties in the U.S. are losing working-age adults; if these declines persist, local economies will falter, tax bases will dry up, and local governments will struggle to maintain services. Growth is not just an option but a necessity — it’s not just that we can afford to have more people, it may be that we can’t afford not to.


    But how does a country get more people? There are two ways: Make them, and invite them in. Increasing the first is relatively difficult — birthrates are declining across the world, and while family-friendly policies may be beneficial for many reasons, they seem to do little to get people to have more babies. On the second method, though, the United States enjoys a significant advantage — people around the globe have long been clamoring to live here, notwithstanding our government’s recent hostility to foreigners. This fact presents a relatively simple policy solution to a vexing long-term issue: America needs more people, and the world has people to send us. All we have to do is let more of them in.


    For decades, the United States has enjoyed a significant economic advantage over other industrialized nations — our population was growing faster, which suggested a more youthful and more prosperous future. But in the last decade, American fertility has gone down. At the same time, there has been a slowdown in immigration.


    The Census Bureau’s latest numbers show that these trends are catching up with us. As of April 1, it reports that there were 331,449,281 residents in the United States, an increase of just 7.4 percent since 2010 — the second-smallest decade-long growth rate ever recorded, only slightly ahead of the 7.3 percent growth during the Depression-struck 1930s.


    The bureau projects that sometime next decade — that is, in the 2030s — Americans over 65 will outnumber Americans younger than 18 for the first time in our history. The nation will cross the 400-million population mark sometime in the late 2050s, but by then we’ll be quite long in the tooth — about half of Americans will be over 45, and one fifth will be older than 85.


    The idea that more people will lead to greater prosperity may sound counterintuitive — wouldn’t more people just consume more of our scarce resources? Human history generally refutes this simple intuition. Because more people usually make for more workers, more companies, and most fundamentally, more new ideas for pushing humanity forward, economic studies suggest that population growth is often an important catalyst of economic growth.


    A declining global population might be beneficial in some ways; fewer people would most likely mean less carbon emission, for example — though less than you might think, since leading climate models already assume slowing population growth over the coming century. And a declining population could be catastrophic in other ways. In a recent paper, Chad Jones, an economist at Stanford, argues that a global population decline could reduce the fundamental innovativeness of humankind. The theory is simple: Without enough people, the font of new ideas dries up, Jones argues; without new ideas, progress could be imperiled.


    There are more direct ways that slow growth can hurt us. As a country’s population grows heavy with retiring older people and light with working younger people, you get a problem of too many eaters and too few cooks. Programs for seniors like Social Security and Medicare may suffer as they become dependent on ever-fewer working taxpayers for funding. Another problem is the lack of people to do all the work. For instance, experts predict a major shortage of health care workers, especially home care workers, who will be needed to help the aging nation.


    In a recent report, Ali Noorani, the chief executive of the National Immigration Forum, an immigration-advocacy group, and a co-author, Danilo Zak, say that increasing legal immigration by slightly more than a third each year would keep America’s ratio of working young people to retired old people stable over the next four decades. 


    As an immigrant myself, I have to confess I find much of the demographic argument in favor of greater immigration quite a bit too anodyne. Immigrants bring a lot more to the United States than simply working-age bodies for toiling in pursuit of greater economic growth. I also believe that the United States’ founding idea of universal equality will never be fully realized until we recognize that people outside our borders are as worthy of our ideals as those here through an accident of birth.

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.”

The article analyzes the relationship of Indigenous Peoples with the public policy of Social Assistance (AS) in Brazil. Based on data collected during field work carried out in 2014, will analyze the case of the Indigenous Reserve of Dourados, Mato Grosso do Sul. In the first part, I characterize the unequal relationship between society and national state with Indigenous Peoples to, then approach the Welfare State politics as an opportunity to face the violation of rights resulting from the colonial siege. Then we will see if Dourados to illustrate the dilemmas and possibilities of autonomy and indigenous role faced with this public policy. It is expected to contribute to the discussion of statehood pointing concrete cases where the local implementation of AS policy is permeable to a greater or lesser extent, the demands of Indigenous Peoples by adaptation to their social organizations and worldviews.

    Cleir Avila Ferreira Júnior was born in Campo Grande, Mato Grosso do Sul State, Brazil. He is a self-taught artist. He has painted professionally since he was 18 years old. He has begun his artistic works with a hyperrealist influence, where he portrayed some regional and ecological themes, especially the Pantanal nature, presented in almost all his art.
    In 1994, he started his mural work on the sides of some Campo Grande’s buildings, as example: the great "Onça Pintada" (50m high and 220m2) took him and his team a month of execution, and the "Tuiuiús" (40m high and 300m2) was his second mural.     In 1995, he painted the "Blue Macaw" (45m high and 430m2).     In 1996, he built the "Macaws’ Monument" in front of the international airport in Campo Grande, MS.     In 1998, he painted a mural of 700m2 in Corumbá, MS, where he portrayed the red macaw in one of its walls and in the other two a big gold fish. Therefore, he did uncountable art around Mato Grosso do Sul State, mainly into the touristic cities.

Opportunity Cost


This phenomenon goes by the name of ‘opportunity cost,’ since by not investing in more equipment and a more rigid production flow, the company is forgoing the opportunity to earn increased profits. These costs are every bite as real as the payment of dollars out-of-pocket.


This notion _______ opportunity cost can be reinforced _________ a famous saying ______ Benjamin Franklin, no slouch himself _________ operations management. To make the point, however, we must make a brief excursion into logic. One truth of logic is the validity of the so-called contrapositive, which says simply that if the statement “If A, then B” is true, then it is also true that “If not B, then not A.” That is, of every time A occurs B follows, then we can be sure that if B does not occur, then A did not occur as well. Enough logic then, and back to Ben Franklin.


One of his Poor Richard sayings is that “A penny saved is a penny earned.” We have all recognized the truth of that since childhood, but I assert that by this saying Ben showed us he knows everything about opportunity cost. After all, what is the contrapositive of “A penny not earned is a penny not saved (i.e., a penny sent). All we are saying by this notion of opportunity cost is that “a penny not earned (an opportunity forgone) is a penny spent.” We shall often have occasion to consider opportunity costs, in analyzing and deciding various operations issues.


SCHMENNER, Roger W. Production/Operations Management. 5th Edition. Prentice-Hall, 1993.

Study the following sentence:


“This phenomenon goes by the name of ‘opportunity cost,’ since by not investing in more equipment and a more rigid production flow, the company is forgoing the opportunity to earn increased profits.”


Analyze the sentences bellow:


1. the word ‘investing’ is being used in the sentence as a continuous verb.

2. the tense used in: ‘goes, is the simple present.

3. the word ‘phenomenon’ is the singular form of ‘phenomena’.

4. the words ‘not investing’ is being used in the present continuous tense.

TEXT
   
   HARVARD BUSINESS REVIEW calls data science “the sexiest job in the 21st century,” and by most accounts this hot new field promises to revolutionize industries from business to government, health care to academia. 
   The field has been spawned by the enormous amounts of data that modern technologies create — be it the online behavior of Facebook users, tissue samples of cancer patients, purchasing habits of grocery shoppers or crime statistics of cities. Data scientists are the magicians of the Big Data era. They crunch the data, use mathematical models to analyze it and create narratives or visualizations to explain it, then suggest how to use the information to make decisions. 
     In the last few years, dozens of programs under a variety of names have sprung up in response to the excitement about Big Data, not to mention the six-figure salaries for some recent graduates. In the fall, Columbia will offer new master’s and certificate programs heavy on data. The University of San Francisco will soon graduate its charter class of students with a master’s in analytics.
      Rachel Schutt, a senior research scientist at Johnson Research Labs, taught “Introduction to Data Science” last semester at Columbia (its first course with “data science” in the title). She described the data scientist this way: “a hybrid computer scientist software engineer statistician.” And added: “The best tend to be really curious people, thinkers who ask good questions and are O.K. dealing with unstructured situations and trying to find structure in them.”
      Eurry Kim, a 30-year-old “wannabe data scientist,” is studying at Columbia for a master’s in quantitative methods in the social sciences and plans to use her degree for government service. She discovered the possibilities while working as a corporate tax analyst at the Internal Revenue Service. She might, for example, analyze tax return data to develop algorithms that flag fraudulent filings, or cull national security databases to spot suspicious activity.
     Some of her classmates are hoping to apply their skills to e-commerce, where data about users’ browsing history is gold.
     “This is a generation of kids that grew up with data science around them — Netflix telling them what movies they should watch, Amazon telling them what books they should read — so this is an academic interest with real-world applications,” said Chris Wiggins, a professor of applied mathematics at Columbia who is involved in its new Institute for Data Sciences and Engineering. “And,” he added, “they know it will make them employable.”
  Universities can hardly turn out data scientists fast enough. To meet demand from employers, the United States will need to increase the number of graduates with skills handling large amounts of data by as much as 60 percent, according to a report by McKinsey Global Institute. There will be almost half a million jobs in five years, and a shortage of up to 190,000 qualified data scientists, plus a need for 1.5 million executives and support staff who have an understanding of data.
      Because data science is so new, universities are scrambling to define it and develop curriculums. As an academic field, it cuts across disciplines, with courses in statistics, analytics, computer science and math, coupled with the specialty a student wants to analyze, from patterns in marine life to historical texts.
    With the sheer volume, variety and speed of data today, as well as developing technologies, programs are more than a repackaging of existing courses. “Data science is emerging as an academic discipline, defined not by a mere amalgamation of interdisciplinary fields but as a body of knowledge, a set of professional practices, a professional organization and a set of ethical responsibilities,” said Christopher Starr, chairman of the computer science department at the College of Charleston, one of a few institutions offering data science at the undergraduate level.
     Most master’s degree programs in data science require basic programming skills. They start with what Ms. Schutt describes as the “boring” part — scraping and cleaning raw data and “getting it into a nice table where you can actually analyze it.” Many use data sets provided by businesses or government, and pass back their results. Some host competitions to see which student can come up with the best solution to a company’s problem.
     Studying a Web user’s data has privacy implications. Using data to decide someone’s eligibility for a line of credit or health insurance, or even recommending who they friend on Facebook, can affect their lives. “We’re building these models that have impact on human life,” Ms. Schutt said. “How can we do that carefully?” Ethics classes address these questions.
       Finally, students have to learn to communicate their findings, visually and orally, and they need business know-how, perhaps to develop new products.

    SPEAKING two languages rather than just one has obvious practical benefits in an increasingly globalized world. But in recent years, scientists have begun to show that the advantages of bilingualism are even more fundamental than being able to converse with a wider range of people. Being bilingual, it turns out, makes you smarter. It can have a profound effect on your brain, improving cognitive skills not related to language and even shielding against dementia in old age. 

     This view of bilingualism is remarkably different from the understanding of bilingualism through much of the 20th century. Researchers, educators and policy makers long considered a second language to be an interference, cognitively speaking, that hindered a child’s academic and intellectual development. 
    They were not wrong about the interference: there is ample evidence that in a bilingual’s brain both language systems are active even when he is using only one language, thus creating situations in which one system obstructs the other. But this interference, researchers are finding out, isn’t so much a handicap as a blessing in disguise. It forces the brain to resolve internal conflict, giving the mind a workout that strengthens its cognitive muscles. 
    Bilinguals, for instance, seem to be more adept than monolinguals at solving certain kinds of mental puzzles. In a 2004 study by the psychologists Ellen Bialystok and Michelle MartinRhee, bilingual and monolingual preschoolers were asked to sort blue circles and red squares presented on a computer screen into two digital bins — one marked with a blue square and the other marked with a red circle. 
    In the first task, the children had to sort the shapes by color, placing blue circles in the bin marked with the blue square and red squares in the bin marked with the red circle. Both groups did this with comparable ease. Next, the children were asked to sort by shape, which was more challenging because it required placing the images in a bin marked with a conflicting color. The bilinguals were quicker at performing this task. 
    The collective evidence from a number of such studies suggests that the bilingual experience improves the brain’s so-called executive function — a command system that directs the attention processes that we use for planning, solving problems and performing various other mentally demanding tasks. These processes include ignoring distractions to stay focused, switching attention willfully from one thing to another and holding information in mind — like remembering a sequence of directions while driving.
    Why does the tussle between two simultaneously active language systems improve these aspects of cognition? Until recently, researchers thought the bilingual advantage stemmed primarily from an ability for inhibition that was honed by the exercise of suppressing one language system: this suppression, it was thought, would help train the bilingual mind to ignore distractions in other contexts. But that explanation increasingly appears to be inadequate, since studies have shown that bilinguals perform better than monolinguals even at tasks that do not require inhibition, like threading a line through an ascending series of numbers scattered randomly on a page.
    The key difference between bilinguals and monolinguals may be more basic: a heightened ability to monitor the environment. “Bilinguals have to switch languages quite often — you may talk to your father in one language and to your mother in another language,” says Albert Costa, a researcher at the University of PompeuFabra in Spain. “It requires keeping track of changes around you in the same way that we monitor our surroundings when driving.” In a study comparing German-Italian bilinguals with Italian monolinguals on monitoring tasks, Mr. Costa and his colleagues found that the bilingual subjects not only performed better, but they also did so with less activity in parts of the brain involved in monitoring, indicating that they were more efficient at it. 
    The bilingual experience appears to influence the brain from infancy to old age (and there is reason to believe that it may also apply to those who learn a second language later in life). 
    In a 2009 study led by Agnes Kovacs of the International School for Advanced Studies in Trieste, Italy, 7-month-old babies exposed to two languages from birth were compared with peers raised with one language. In an initial set of trials, the infants were presented with an audio cue and then shown a puppet on one side of a screen. Both infant groups learned to look at that side of the screen in anticipation of the puppet. But in a later set of trials, when the puppet began appearing on the opposite side of the screen, the babies exposed to a bilingual environment quickly learned to switch their anticipatory gaze in the new direction while the other babies did not. 
    Bilingualism’s effects also extend into the twilight years. In a recent study of 44 elderly Spanish-English bilinguals, scientists led by the neuropsychologist Tamar Gollan of the University of California, San Diego, found that individuals with a higher degree of bilingualism — measured through a comparative evaluation of proficiency in each language — were more resistant than others to the onset of dementia and other symptoms of Alzheimer’s disease: the higher the degree of bilingualism, the later the age of onset.
    Nobody ever doubted the power of language. But who would have imagined that the words we hear and the sentences we speak might be leaving such a deep imprint?
