Teaching English as a foreign language teacher: job description
Teaching English as a foreign language (TEFL) involves teaching adults and children whose first or main language is not English. This can be done in the UK or abroad and the students may be learning English for either business or leisure reasons.
Teaching English to speakers of other languages (TESOL) is also a widely used term and often means the same thing as TEFL. It’s sometimes specifically used to refer to teaching English to people who are living in the UK but who do not speak English as a first language. These students are most commonly refugees and immigrants and need to learn the language in order to help them settle into the UK society.Their courses are often government funded.
Teaching English as a second language (TESL) or teaching English as an additional language (TEAL) may also be terms that are used but they generally all refer to the same thing - teaching English to someone whose native language is not English.
Teachers of English as a foreign language can work in a variety of settingswith different age ranges. This can include commercial language schools, schools and institutions of further and higher education throughout the UK and overseas. Some may also teach in industry, while others are self-employed. Classes are usually taught in English, evenwith beginners. Teaching English as a foreign language teacher: job description

A man stepped onto the overnight train and told the conductor, “I need you to wake me up in Philadelphia. I'm a deep sleeper and can be angry when I get up, but no matter what, I want you to help me make that stop. Here's $100 to make sure".
The conductor agreed. The man fell asleep, and when he awoke he heard the announcement that the train was approaching New York, which meant they had passed Philadelphia a long time ago. Furious, he ran to the conductor. “I gave you $100 to make sure I got off in Philadelphia, you idiot!" “Wow," another passenger said to his traveling companion. “Is that guy mad!" “Yeah," his companion replied. “But not half as mad as that guy they forced off the train in Philadelphia."

Police and Human Rights – Manual for Police Training
How can respecting human rights help the police?
Respect for human rights by law enforcement agencies actually enhances the effectiveness of those agencies. Where human rights are systematically respected, police officers have developed professionalism in their approaches to solving and preventing crime and maintaining public order. In this sense, respect for human rights by police is, in addition to being a moral, legal and ethical imperative, also a practical requirement for law enforcement. When the police are seen to respect, uphold and defend human rights:
• Public confidence is built and community cooperation fostered.
• Legal prosecutions are successful in court. • Police are seen as part of the community, performing a valuable social function.
• The fair administration of justice is served, and, consequently, confidence in the system.
• An example is set for respect for the law by others in the society.
• Police are able to be closer to the community, and, therefore, in a position to prevent and solve crimes through proactive policing.
• Support is elicited from the media, from the international community, and from higher authorities.
• A contribution is made to the peaceful resolution of conflicts and complaints.
An effective police service is one that serves as the first line of defense in the protection of human rights. Its members carry out their work in a way, which does not rely upon fear and raw power but, on the contrary, is based on regard for the law, honor, and professionalism.
What role does training play in protecting human rights?
The effective training of police in human rights is an essential element in the global efforts to promote and protect human rights in every country. In order to protect human rights, the police must first know and understand them. Furthermore, police officers must be familiar with the various international guidelines and bodies of principles – such as the Code of Conduct for law enforcement officials and the principles on the use of force and firearms – and be able to use them as tools in their everyday work. They must understand the fact that international human rights standards concerning their work were developed to provide invaluable guidance for the performance of their crucial functions in a democratic society. However, police officers in the line of duty should know not only what the rules are, but also how to do their job effectively within the confines of those rules.
Most people have heard the argument that respect for human rights is somehow opposed to effective law enforcement. And effective law enforcement means to capture the criminal. And to secure his conviction, it is necessary to “bend the rules” a little. A tendency to use overwhelming force in controlling demonstrations, physical pressure to extract information from detainees, or excessive force to secure an arrest can be observed now and then. In this way of thinking, law enforcement is a war against crime, and human rights are merely obstacles thrown in the path of the police by lawyers and NGOs. In fact, violations of human rights ––78–––– police only make the already challenging task of law enforcement ––– 79––– . When the law enforcer ––– 80––– the lawbreaker, the result is an assault on human dignity, on the law itself and on all institutions of public authority.

Japan’s shipyards remain intact after quake
Japan’s major shipyards escaped the full impact of the March 11 earthquake and tsunami that struck the northeastern coast of the country with full force. An official at the Japan Ship Exporters’ Association said the devastating natural disaster “will have no impact on future export ship orders at all”. Although several small shipyards in the quake-hit areas were affected, major Japanese shipyards that build large vessels for exports are concentrated in western Japan and remain intact, the official said. Mitsui Engineering & Shipbuilding sustained “slight material damages” in the company’s Kasai Center and Chiba Works but did not consider such slight damages would cause serious impact on operations. “The rotational schedule of interruption of power supply due to the earthquake may affect our operation at our works and subsidiaries. However, the degree of the impact is not known now,” the company said in a statement. Japanese export ship orders rose for the 15th consecutive month in February o a year-on-year basis. Japanese shipbuilders received orders for 277 export vessels – 259 bulk carriers, 10 oil tankers and eight general cargo vessels – in the April-February period.

Tsnunami Debris Expected on U.S. Shores in 3 Years
The powerful tsunami triggered by the 9.0 Japanese earthquake destroyed coastal towns near Sendai, washing such things as houses and cars into the ocean. Projections of where this debris might head have been made at the international Pacific Research Center, university of Hawaii at Manoa. What their model predicts about the tsunami debris is that they first spread out eastward from the Japan Coast in the North Pacific Subtropical Gyre. In a year, the Papahanaumokuakea Marine National Monument will see pieces washing up on its shores; in two years, the remaining Hawaiian islands will see some effects; in three years, the plume will reach the US West Coast, dumping debris on Californian beaches and the beaches of British Columbia, Alaska, and Baja California. The debris will then drift into the famous floating junk yard, the North Pacific Garbage Patch, where it will wander around and break into smaller and smaller pieces. In five years, Hawaii shores can expect to see another barrage of debris that is stronger and longer-lasting than the first one. Much of the debris leaving the North Pacific Garbage Patch ends up on Hawaii’s reefs and beaches. These model projections will help to guide clean-up and tracking operations.

What to Know About the Controversy Surrounding the Movie Green Book
Depending on who you ask, Green Book is either the pinnacle of movie magic or a whitewashing sham.
The film, which took home the prize for Best Picture at the 91st Academy Awards, as well as honors for Mahershala Ali as Best Supporting Actor and Nick Vallelonga, Brian Currie and Peter Farrelly for Best Original Screenplay, depicts the burgeoning friendship between a black classical pianist and his ItalianAmerican driver as they travel the 1960s segregated South on a concert tour. But while Green Book was an awards frontrunner all season, its road to Oscar night was riddled with missteps and controversies over its authenticity and racial politics.
Green Book is about the relationship between two real-life people: Donald Shirley and Tony “Lip” Vallelonga. Shirley was born in 1927 and grew up in a well-off black family in Florida, where he emerged as a classical piano prodigy: he possessed virtuosic technique and a firm grasp of both classical and pop repertoire. He went on to perform regularly at Carnegie Hall— right below his regal apartment—and work with many prestigious orchestras, like the Chicago Symphony and the New York Philharmonic. But at a time when prominent black classical musicians were few and far between due to racist power structures, he never secured a spot in the upper echelons of the classical world. (African Americans still only make up 1.8 percent of musicians playing in orchestras nationwide, according to a recent study.)
Vallelonga was born in 1930 to working-class Italian parents and grew up in the Bronx. As an adult he worked as a bouncer, a maître d’ and a chauffeur, and he was hired in 1962 to drive Shirley on a concert tour through the Jim Crow South. The mismatched pair spent one and a half years together on the road — though it’s condensed to just a couple of months in the film — wriggling out of perilous situations and learning about each other’s worlds. Vallelonga would later become an actor and land a recurring role on The Sopranos.
In the 1980s, Vallelonga’s son, Nick, approached his father and Shirley about making a movie about their friendship. For reasons that are now contested, Shirley rebuffed these requests at the time. […]

A Oração: “Doctors are investigating 29 related infant deaths” encontra-se em que tempo verbal?
TEXT
Clifford the Big Red Dog looks fabulous on an iPad. He sounds good, too — tap the screen and hear him pant as a blue truck roars into the frame. “Go, truck, go!” cheers the narrator. But does this count as story time? Or is it just screen time for babies? It is a question that parents, pediatricians and researchers are struggling to answer as children’s books, just like all the other ones, migrate to digital media.
For years, child development experts have advised parents to read to their children early and often, citing studies showing its linguistic, verbal and social benefits. In June, the American Academy of Pediatrics advised doctors to remind parents at every visit that they should read to their children from birth, prescribing books as enthusiastically as vaccines and vegetables.
On the other hand, the academy strongly recommends no screen time for children under 2, and less than two hours a day for older children.
At a time when reading increasingly means swiping pages on a device, and app stores are bursting with reading programs and learning games aimed at infants and preschoolers, which bit of guidance should parents heed?
The answer, researchers say, is not yet entirely clear. “We know how children learn to read,” said Kyle Snow, the applied research director at the National Association for the Education of Young Children. “But we don’t know how that process will be affected by digital technology.”
Part of the problem is the newness of the devices. Tablets and e-readers have not been in widespread use long enough for the sorts of extended studies that will reveal their effects on learning.
Dr. Pamela High, the pediatrician who wrote
the June policy for the pediatrics group, said
electronic books were intentionally not addressed.
“We tried to do a strongly evidence-based policy
statement on the issue of reading starting at a very
young age,” she said. “And there isn’t any data,
really, on e-books.”
But a handful of new studies suggest that reading to a child from an electronic device undercuts the dynamic that drives language development. “There’s a lot of interaction when you’re reading a book with your child,” Dr. High said. “You’re turning pages, pointing at pictures, talking about the story. Those things are lost somewhat when you’re using an e-book.”
In a 2013 study, researchers found that children ages 3 to 5 whose parents read to them from an electronic book had lower reading comprehension than children whose parents used traditional books. Part of the reason, they said, was that parents and children using an electronic device spent more time focusing on the device itself than on the story (a conclusion shared by at least two other studies).
“Parents were literally putting their hands over the kids’ hands and saying, ‘Wait, don’t press the button yet. Finish this up first,’ ” said Dr. Julia Parish-Morris, a developmental psychologist at Children’s Hospital of Philadelphia and the lead author of the 2013 study that was conducted at Temple University. Parents who used conventional books were more likely to engage in what education researchers call “dialogic reading,” the sort of back-and-forth discussion of the story and its relation to the child’s life that research has shown are key to a child’s linguistic development.
Complicating matters is that fewer and fewer children’s e-books can strictly be described as books, say researchers. As technology evolves, publishers are adding bells and whistles that encourage detours. “What we’re really after in reading to our children is behavior that sparks a conversation,” said Kathy Hirsh-Pasek, a professor of psychology at Temple and co-author of the 2013 study. “But if that book has things that disrupt the conversation, like a game plopped right in the middle of the story, then it’s not offering you the same advantages as an old-fashioned book.”
Of course, e-book publishers and app developers point to interactivity as an educational advantage, not a distraction. Many of those bells and whistles — Clifford’s bark, the sleepy narration of “Goodnight Moon,” the appearance of the word “ham” when a child taps the ham in the Green Eggs and Ham app — help the child pick up language, they say.
There is some evidence to bear out those claims, at least in relation to other technologies. A study by the University of Wisconsin in 2013 found that 2-year-olds learned words faster with an interactive app as opposed to one that required no action.
But when it comes to learning language, researchers say, no piece of technology can substitute for a live instructor — even if the child appears to be paying close attention.
Patricia K. Kuhl, a director of the Institute for Learning and Brain Sciences at the University of Washington, led a study in 2003 that compared a group of 9-month-old babies who were addressed in Mandarin by a live instructor with a group addressed in Mandarin by an instructor on a DVD. Children in a third group were exposed only to English.
“The way the kids were staring at the screen, it seemed obvious they would learn better from the DVDs,” she said. But brain scans and language testing revealed that the DVD group “learned absolutely nothing,” Dr. Kuhl said. “Their brain measures looked just like the control group that had just been exposed to English.
The only group that learned was the live social interaction group.” In other words, “it’s being talked with, not being talked at,” that teaches children language, Dr. Hirsh-Pasek said.
Similarly, perhaps the biggest threat posed
by e-books that read themselves to children, or
engage them with games, is that they could lull
parents into abdicating their educational
responsibilities, said Mr. Snow of the National
Association for the Education of Young Children.
“There’s the possibility for e-books to become the TV babysitters of this generation,” he said. “We don’t want parents to say, ‘There’s no reason for me to sit here and turn pages and tell my child how to read the word, because my iPad can do it.’ ”
But parents may find it difficult to avoid resorting to tablets. Even literacy advocates say the guidelines can be hard to follow, and that allowing limited screen time is not high on the list of parental missteps. “You might have an infant and think you’re down with the A.A.P. guidelines, and you don’t want your baby in front of a screen, but then you have a grandparent on Skype,” Mr. Snow said. “Should you really be tearing yourself apart? Maybe it’s not the world’s worst thing.”
“The issue is when you’re in the other room and Skyping with the baby cause he likes it,” he said. Even if screen time is here to stay as a part of American childhood, good old-fashioned books seem unlikely to disappear anytime soon. Parents note that there is an emotional component to paper-andink storybooks that, so far, does not seem to extend to their electronic counterparts, however engaging.

A Brief and Simplified Description of Papermaking
The paper we use today is created from individual wood fibers that are first suspended in water and then pressed and dried into sheets. The process of converting the wood to a suspension of wood fibers in water is known as pulp making, while the manufacture of the dried and pressed sheets of paper is formally termed papermaking. The process of making paper has undergone a steady evolution, and larger and more sophisticated equipment and better technology continue to improve it.
The Wood yard and Wood rooms
The process at Androscogging began with receiving wood in the form of chips or of logs 4 or 8 feet in length. From 6 AM to 10 PM a steady stream of trucks and railroad cars were weighted and unloaded. About 40 percent were suplied by independents who were paid by weight their logs. The mill also received wood chips from lumber mills in the area. The chips and logs were stored in mammoth piles with separate piles for wood of different species (such as pine, spruce, hemlock).
When needed, logs were floated in flumes......(1).....the wood yard.....(2).....one of the mill’s three wood rooms. There, bark was rubbed......(3)........in long, ribbed debarking drums by tumbling the logs against one another. The logs then fell into a chipper;......(4)......seconds a large log was reduced to a pile of chips approximately 1 inch by 1 inch by 1/4 inch.
The chips were stored in silos. There were separate silos for softwoods (spruce, fir, hemlock, and pine) and hardwoods (maple, oak, beech, and birch). This separate and temporary storage of chips permitted the controlled mixing of chips into the precise recipe for the grade of paper being produced.
The wood chips were then sorted through large, flat vibrating screens. Oversized chips were rechipped, and ones that were too small were collected for burning in the power house. (The mill provided approximately 20 percent of all its own steam and electricity needs from burning waste. An additional 50 percent of total electricity needs was produced by harnessing the river for hydroelectric power.)
Once drawn from the silo into the digesters, there was no stopping the flow of chips into paper.
Pulpmaking
The pulp made at Androscoggin was of two types: Kraft pulp (produced chemically) and ground wood pulp (produced mechanically). Kraft pulp was far more important to the high quality white papers produced at Androscoggin, accounting for 80 percent of all the pulp used. Kraft pulp makes strong paper. (Kraft is German for strength. A German invented the Kraft pulp process in 1884.) A paper’s strength generally comes from the overlap and binding of long fibers of softwood; only chemically was it initially possible to separate long wood fibers for suspension in water. Hardwood fibers are generally smaller and thinner and help smooth the paper and make it less porous.
The ground wood pulping process was simpler and less expensive than the Kraft process. It took high quality spruce and fir logs and pressed them continuously against a revolving stone that broke apart the wood’s fibers. The fibers, however, were smaller than those produced by the Kraft process and, although used to make newsprint, were useful at Androscoggin in providing “fill” for the coated publication gloss papers of machines 2 and 3, as will be described later.
(A)The chemical Kraft process worked by dissolving the lignin that bonds wood fibers together. (B) It did this in a tall pressure cooker, called a digester, by “cooking” the chips in a solution of caustic soda (NaOH) and sodium sulfide (Na2S), which was termed the “white liquor.” (C)The two digesters at Androscoggin were continuous digesters; chips and liquor went into the top, were cooked together as they slowly settled down to the bottom, and were drawn off the bottom after about three hours. (D) By this time, the white liquor had changed chemically to “black liquor’’; the digested chips were then separated from this black liquor. (E)
In what was known as the “cold blow” process, the hot, pressurized chips were gradually cooled and depressurized. A “cold liquor’’ (170°F) was introduced to the bottom of the digester and served both to cool and to transport the digested chips to a diffusion washer that washed and depressurized the chips. Because so much of the lignin bonding the fibers together had been removed, the wood fiber in the chips literally fell apart at this stage.
The black liquor from the digester entered a separate four-step recovery process. Over 95 percent of the black liquor could be reconstituted as white liquor, thereby saving on chemical costs and significantly lowering pollution. The four-step process involved (1) washing the black liquor from the cooked fiber to produce weak black liquor, (2) evaporating the weak black liquor to a thicker consistency, (3) combustion of this heavy black liquor with sodium sulfate (Na2SO4 ), and redissolving the smelt, yielding a “green liquor” (sodium carbonate + sodium sulfide), and (4) adding lime, which reacted with the green liquor to produce white liquor. The last step was known as causticization.
Meanwhile, the wood-fiber pulp was purged of impurities like bark and dirt by mechanical screening and by spinning the mixture in centrifugal cleaners. The pulp was then concentrated by removing water from it so that it could be stored and bleached more economically.
By this time, depending on the type of pulp being made, it had been between 3 1/2 and 5 hours since the chips had entered the pulp mill.
All the Kraft pulp was then bleached. Bleaching took between 5 and 6 hours. It consisted of a three-step process in which (1) a mix of chlorine (Cl2 ) and chlorine dioxide (CIO2 ) was introduced to the pulp and the pulp was washed; (2) a patented mix of sodium hydroxide (NaOH), liquid oxygen, and hydrogen peroxide (H2 O2 ) was then added to the pulp and the pulp was again washed; and (3) chlorine dioxide (ClO2 ) was introduced and the pulp washed a final time. The result was like fluffy cream of wheat. By this time the pulp was nearly ready to be made into paper.
From the bleachery, the stock of pulp was held for a short time in storage (a maximum of 16 hours) and then proceeded through a series of blending operations that permitted a string of additives (for example, filler clay, resins, brighteners, alum, dyes) to be mixed into the pulp according to the recipe for the paper grade being produced. Here, too, “broke” (paper wastes from the mill itself) was recycled into the pulp. The pulp was then once again cleaned and blended into an even consistency before moving to the papermaking machine itself.
It made a difference whether the broke was of coated
or uncoated paper, and whether it was white or colored. White, uncoated paper could be recycled immediately. Colored, uncoated paper had to be rebleached.
Coated papers, because of the clays in them, could not
be reclaimed.

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.
