Still, Europe is in a stronger position now than in 2009. Five years ago, 80 per cent of Russian gas was piped across Ukraine, whereas now less than 50 per cent takes that route, thanks to the Nord Stream pipeline under the Baltic sea.

Total executives have predicted that Russia will be the largest contributor to the group’s oil production by 2020.

Total has also indicated that it intends to increase its stake in Novatek, one of whose major shareholders, Gennady Timchenko, is on the US blacklist.

“Novatek is not subject to sanctions. So we work with Novatek as before and we will continue.”

There is nothing new in the need to address possible discrimination of imported electricity by Germany,” he said. “If consumers have to pay a surcharge on their consumption of both domestic and imported electricity but revenue from the surcharge is used to only finance domestic electricity producers, there is a risk that imported electricity is disadvantaged and made comparatively more expensive.”

Carefully taught, the assignments can help make math more concrete. Students don’t just memorize their times tables and addition facts but also understand how arithmetic works and how to apply it to real-life situations. But in practice, most teachers are unprepared and children are baffled, leaving parents furious.

On national tests, nearly two-thirds of fourth graders and eighth graders are not proficient in math. More than half of fourth graders taking the 2013 National Assessment of Educational Progress could not accurately read the temperature on a neatly drawn thermometer.

On the same multiple-choice test, three-quarters of fourth graders could not translate a simple word problem about a girl who sold 15 cups of lemonade on Saturday and twice as many on Sunday into the expression “15 + (2×15).” Even in Massachusetts, one of the country’s highest-performing states, math students are more than two years behind their counterparts in Shanghai.

A 2012 study comparing 16-to-65-year-olds in 20 countries found that Americans rank in the bottom five in numeracy.

One study that examined medical prescriptions gone awry found that 17 percent of errors were caused by math mistakes on the part of doctors or pharmacists.

“I’m just not a math person,” Lampert says her education students would say with an apologetic shrug.

In the 1970s and the 1980s, cognitive scientists studied a population known as the unschooled, people with little or no formal education.

For instance, many of the workers charged with loading quarts and gallons of milk into crates had no more than a sixth-grade education. But they were able to do math, in order to assemble their loads efficiently, that was “equivalent to shifting between different base systems of numbers.”

Studies of children in Brazil, who helped support their families by roaming the streets selling roasted peanuts and coconuts, showed that the children routinely solved complex problems in their heads to calculate a bill or make change.

The cognitive-science research suggested a startling cause of Americans’ innumeracy: school.

Only when the company held customer focus groups did it become clear why. The Third Pounder presented the American public with a test in fractions. And we failed. Misunderstanding the value of one-third, customers believed they were being overcharged. Why, they asked the researchers, should they pay the same amount for a third of a pound of meat as they did for a quarter-pound of meat at McDonald’s. The “4” in “¼,” larger than the “3” in “⅓,” led them astray.

In the process, she gave them an opportunity to realize, on their own, why their answers were wrong.

At most education schools, the professors with the research budgets and deanships have little interest in the science of teaching

The answer-getting strategies may serve them well for a class period of practice problems, but after a week, they forget. And students often can’t figure out how to apply the strategy for a particular problem to new problems.

Some of the failure could be explained by active resistance.

A year after he got to Chicago, he went to a one-day conference of teachers and mathematicians and was perplexed by the fact that the gathering occurred only twice a year.

More distressing to Takahashi was that American teachers had almost no opportunities to watch one another teach.

In Japan, teachers had always depended on jugyokenkyu, which translates literally as “lesson study,” a set of practices that Japanese teachers use to hone their craft. A teacher first plans lessons, then teaches in front of an audience of students and other teachers along with at least one university observer. Then the observers talk with the teacher about what has just taken place. Each public lesson poses a hypothesis, a new idea about how to help children learn.

The research showed that Japanese students initiated the method for solving a problem in 40 percent of the lessons; Americans initiated 9 percent of the time.

Finland, meanwhile, made the shift by carving out time for teachers to spend learning. There, as in Japan, teachers teach for 600 or fewer hours each school year, leaving them ample time to prepare, revise and learn. By contrast, American teachers spend nearly 1,100 hours with little feedback.

“Sit on a stone for three years to accomplish anything.”

In one experiment in which more than 200 American teachers took part in lesson study, student achievement rose, as did teachers’ math knowledge — two rare accomplishments.

Examining nearly 3,000 teachers in six school districts, the Bill & Melinda Gates Foundation recently found that nearly two-thirds scored less than “proficient” in the areas of “intellectual challenge” and “classroom discourse.”

The third principle is that the ban on exports of dual-use technology, which applies to military and civilian products, will for now be limited to military end-users.

The ECB’s Outright Monetary Transactions programme was instrumental in reducing Spanish government bond yields. This alleviated the Spanish fiscal position, but did not make it sustainable. The continuing unsustainability of the Spanish government debt has to do with two factors: First while r (the interest rate) declined, g (nominal growth) remained much lower in Spain than in the UK. The latter was due to the deflationary forces in the Eurozone – themselves a result of excessive austerity and the absence of currency depreciation (which was made possible in the UK thanks to the expansionary monetary policies of the Bank of England).

about 1.3 percent of GDP is devoted to the military.

Poland's President Bronislaw Komorowski announced Tuesday that Poland would raise that figure to 2 percent as "a very tangible, very clear engagement" in the alliance

1.2 percent of its GDP on the military

1.3 percent of its GDP on the military.

Germany is reducing the size of its army, which is expected to slightly trim military spending in coming years.

inancially challenged Spain's defense budget has shrunk from 1.2 percent of GDP in 2009 to 0.9 percent, NATO statistics show.

There is even talk of Russia and China creating an alternative international payment system to replace the SWIFT system, which the US and Europe can use to impose financial sanctions against Russia.

But Putin is ambitious, and – like other autocrats in Central Asian nations – he may remain in power for decades to come. And, like it or not, even a Russia that lacks the dynamism needed to succeed in manufacturing and the industries of the future will remain a commodity-producing

superpower.

US President Barack Obama says that this is not the beginning of a new Cold War; current trends may soon suggest otherwise.

“I definitely expect that things will get worse,” he said.

The European Union exported agricultural goods worth 11.8 billion euros, or $15.8 billion, to Russia last year, and sales have been rising at a rate of almost 15 percent a year.

Some economists argue that the region is already well into a so-called lost decade.

Separately, the German Federal Statistical Office reported on Wednesday that new industrial orders in Germany fell 3.2 percent in June compared with May. Analysts had expected orders to increase.

For Italy, the deteriorating economy puts greater pressure on Prime Minister Matteo Renzi, who less than a week ago promised not to impose any more government budget cuts and to invest in improving the country’s roads and other infrastructure. Such promises will be difficult to keep if slower growth, which usually translates into higher unemployment and lower corporate profits, limits tax receipts.A slower economy also endangers Italy’s ability to comply with eurozone rules on budget deficits.

Italy’s 2.1 trillion euro government debt equals 136 percent of its annual gross domestic product, the second-highest debt ratio in the eurozone, after Greece.

They said Italy’s problems stemmed more from its failure make changes needed to improve the performance of its economy.

The slow pace of structural reforms is worrisome,” said Paolo Manasse, a professor of macroeconomics at Bologna University. He said there was no sign of progress on necessary steps like selling off state-owned assets or overhauling the labor market or public pension system.

In the case of driving schools, the government offers only a limited number of exams each year, and these are doled out to the driving schools depending on their success rate the year before. That fact alone gives the old guard a virtual monopoly,

calling for an overhaul of the written test, which he says goes far beyond making sure that a person knows the rules of the road.

Some studies have concluded that the French are probably paying 20 percent more than they should for the services they get from regulated professions, which include notaries, lawyers, bailiffs, ambulance drivers, court clerks, driving instructors and more.

barriers to getting a license are so high that about one million French people, who should have licenses, have never been able to get them.

Mr. Kramarz said that it often costs 3,000 euros, or about $3,900, to get a license. But others said the average was closer to 1,500 to 2,000 euros.

Although students are required to take only 20 hours of driving lessons, most end up doing double that while they wait for a chance to take the test.

The country should also use its political clout to convince its partners and Brussels to implement a European reform agenda that targets investment and growth.
