"The US happens to have a very high fraction of low-social-class kids taking the PISA test," said Carnoy. "The composition of our test sample is very different from the higher-scoring countries and post-industrial countries. If you want to more clearly see how much students are getting from the school, you have to find some way to control for their families."
3 Types Of Burglar Bait: Are You One? (Kevin R.)
Renters: Known rental properties, particularly city apartments, are magnetic to burglars. If you were a burglar, wouldn't you target a place where the neighbors don't know each other and people are going in and out all the time? The Justice Department found that people living in rental properties were at a higher risk for burglary across the board, regardless of family composition or whether anyone was home at the time. Another study, by the nonprofit Center for Problem-Oriented Policing, found that "neighborhoods with higher mobility—those with shorter-term residents—tend to have higher burglary rates." A high-rise is practically a buffet.
Often called "frozen smoke", aerogels are among the amazing materials of our time, with fifteen Guinness Book of World Records entries to their name. However, despite their list of extreme properties, traditional aerogels are brittle, crumbling and fracturing easily enough to keep them out of many practical applications. A new class of mechanically robust polymer aerogels discovered at NASA's Glenn Research Center in Ohio may soon enable engineering applications such as super-insulated clothing, unique filters, refrigerators with thinner walls, and super-insulation for buildings.
Teak is one of the most valuable hardwoods and planted teak forests have attracted investment in Africa, Asia and Latin America, according to a March 2012 report by the Food and Agriculture Organization. Processed timber can retail at prices from $750 per cubic meter (35.3 cubic feet) to $1,500 per cubic meter, according to ETC. Globally, teak constitutes the only planted hardwood resource that is increasing in terms of area, the FAO said.
“The German confidence number is a pretty good sign that the economy is improving,” said Michael Lynch, president of Strategic Energy & Economic Research in Winchester, Massachusetts. “We have a better economic outlook and more people are expecting stronger growth and higher oil demand.”
Most US rigs still run on diesel, but the number converting to natural gas is growing, mostly due to the facts that natural gas is cheaper and releases fewer emissions. Caterpillar (NYSE:CAT), Halliburton (NYSE:HAL), and Schlumberger (NYSE:SLB) all worked to convert Apache’s rig to run on natural gas, which has led to an estimated saving of 40% on fuel costs.
Late Thursday, a gas-powered heater and a tent were the only defense Youssef had against the biting cold as he handed out jackets and sweaters at a makeshift supply depot he established to help his Midland Beach neighbors who, in some cases, are still struggling to get the power back on.
"A lot of people have been coming, so we give them jackets, we give them sweaters," he told CNN affiliate NY1. "Yeah, we are trying. We are trying our best to help them."
IBM And Waterfund To Develop A Water Cost Index (Thomas C.)
With advances in technology — deep computing and Big Data analytics linked to sophisticated sensor networks and smart meters — IBM is helping clients and partners make smarter decisions about water management. By monitoring, measuring and analyzing water systems, from rivers and reservoirs to pumps and pipes, we can better understand the issues around water. IBM is applying its expertise in smart systems and Big Data to help companies, governments and citizens understand and more effectively deal with these issues.
