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

     The ability of a helicopter to hover and land almost anywhere makes it an enormously useful machine. But helicopters have their limitations, particularly when it comes to flying fast. In a recent series of test flights, a new type of chopper has begun smashing speed records.

     The x2 is an experimental helicopter being developed by Sikorsky, an American company, which hopes it will be zipping along at more than 460kph. The company, however, is interested in more than just breaking speed records. It plans to use the technology developed for the x2 in commercial helicopters.

     Sikorsky reckons that future helicopters built using the x2 technology would be extremely versatile machines. They would dash to and from a medical emergency a lot faster. They would also be very agile in flight, which would increase their capabilities in combat.

Lawsuits claim Knoedler made huge profits on fakes

For more than a dozen years the Upper East Side gallery Knoedler & Company was “substantially dependent” on profits it made from selling a mysterious collection of artwork that is at the center of a federal forgery investigation, former clients of this former gallery have charged in court papers. The analysis is based on financial records turned over as part of a lawsuit against the gallery filed by Domenico and Eleanore De Sole, who in 2004 paid $8.3 million for a painting attributed to Mark Rothko that they now say is a worthless fake. The Rothko is one of approximately 40 works that Knoedler, which closed last year, obtained from Glafira Rosales, a littleknown dealer whose collection of works attributed to Modernist masters has no documented provenance and is the subject of an F.B.I. investigation. Between 1996 and 2008, the suit asserts, Knoedler earned approximately $60 million from works that Ms. Rosales provided on consignment or sold outright to the gallery and cleared $40 million in profits. In one year, 2002, for example, the complaint says the gallery’s entire profit — $5.6 million — was derived from the sale of Ms. Rosales’s works. “Knoedler’s viability as a business was substantially — and, in some years, almost entirely — dependent on sales from the Rosales Collection,” the De Soles claimed last month in an amended version of the suit they filed this year. While the forgery allegations are well known and have been the subject of three federal lawsuits against Knoedler, the recent filings expand the known number of Rosales artworks that were handled by the gallery, which was in business for 165 years, and assert that they played a pivotal role in the gallery’s success. After the F.B.I. issued subpoenas to the gallery in the fall of 2009, Michael Hammer, Knoedler’s owner, halted the sale of any Rosales works. Knoedler ended up losing money that year and in 2010, the court papers say. http://www.nytimes.com/2012/10/22/arts/design/knoe...

Model copes with chaos to deliver relief Computer program helps responders transport supplies in tough conditions
By Rachel Ehrenberg Science News, Web edition: Monday, February 21st, 2011
WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.

'CityVille' now bigger on Facebook than 'FarmVille'
(Mashable) -- Facebook game developer Zynga has proved once
again that it knows exactly what it needs to do to keep millions of
Facebook users happy and occupied.
In less than a month, its latest game "CityVille"___ ______
(become) the most popular application on Facebook, surpassing
Zynga's previous hit "FarmVille" in all areas.
According to AppData, "CityVille" now has 16.8 million daily
active users, compared to "FarmVille's" 16.4 million. Looking at
monthly active users, "CityVille" is also ahead with 61.7 million
users, while "FarmVille" trails behind with 56.8 million users.
Zynga's "FrontierVille" and "Texas HoldEm Poker" also round out
the top five: put those four apps together (we'll disregard the fact
that many of those users overlap for a second) and you have a
very impressive number: 184 million active users across four
games.
The only non-Zynga app in the top five list is "Phrases," _____ at
one point threatened to take the top place, but is now
overshadowed by both "CityVille" and "FarmVille."
"CityVille's" future success wasn't hard to predict after an
amazingly good start at the beginning of December, but it's still
impressive to see Zynga amassing tens of millions of users in a
matter of days, proving that all that venture capital that went into
the company isn't there by accident.

Brazil is one of the world's fastest growing economies
with enormous energy requirements. The growing consumer
base coupled with rapid industrial development has infused the
overall energy demand and encouraged natural gas
consumption in the country. The volatile international crude oil
prices as well as the cheaper and environment-friendly nature of
natural gas have further boosted the use of natural gas
throughout the country. This has resulted in enormous demand
for gas flow measurement and supervision devices in the
country which is all set to uplift the sales and deployment of gas
meters.

According to our latest research report "Brazil Gas Meter
Market Forecast to 2013", Brazil gas meter industry is being
increasingly benefitted by surging piped natural gas
consumption in the residential, commercial, industrial and
automobile sectors. The natural gas distribution network
reached around 18,400 Km in 2009. In order to strictly supervise
the gas flow measurement and to accurately measure its
quantity, the utilities are rapidly deploying gas meter devices in
their transportation network. These utilities are not only installing
conventional gas meters, but also rapidly opting advanced
metering devices such as AMR and AMI to ensure accurate and
immediate information on gas consumption. This adoption has
enabled utilities to automate their gas distribution networks and
upgrade safety standards in their routine operations.
