Screening, in general, is the investigation of a great number of something (for instance, people) looking for those with a particular problem or feature. One example is at an airport, where many bags get x-rayed to try to detect any which may contain weapons or explosives. People are also screened going through a metal detector. Even though the procedure aims at a large number of screens, it is always equivalent to sampling in statistics, because the complete population is almost always unaccessible for screening.

Screening has other, more specific meanings:

• In physics, electric field screening refers to the dampening of an electric field by mobile charges
• Screening (economics)
• Screening (medicine)
• Screening for pharmacological activity during drug discovery
• part of the process of Environmental impact assessment.
• hampering an opponent's attempts at reconnaissance
• a type of tactic (sometimes legal, sometimes not) in sport games such as basketball or volleyball
• a screening can refer to the display of a film in a movie theatre or screening room

LiveUniverse Buys Another Loser: Peerflix
Jason Kincaid Sat, 06 Sep 2008 02:01:21 -0000
We're getting reports that Peerflix, the tumultuous company that switched from acting as a DVD-swapping service to an ad network, has been acquired by Brad Greenspan's LiveUniverse for an undisclosed amount (though we're guessing it's pretty low). We've asked LiveUniverse to comment. Peerflix was founded in 2004 as a "peer-to-peer Netflix", helping users to swap DVDs they owned for a dollar. The site abandoned the flat fixed pricing scheme for a demand-based model in 2006, but that didn't work well either: in November 2007 it decided to launch a media network that had nothing to do with its original DVD swapping service. Peerflix finally canned the DVD trading business earlier this year, so Live Universe is acquiring it solely for its ad network.

SideTaker: Crowdsourcing Your Private Disputes, With Hilarious Results
Jason Kincaid Fri, 05 Sep 2008 23:45:19 -0000
Every couple has its ups and downs, but most people try to keep their dirty laundry to themselves. But what about those times when you just can't come to an agreement with your significant other? Today sees the launch of SideTaker a site that asks couples to upload both sides of their arguments and let the crowd settle their debates. SideTaker members can vote on which side they agree with, or leave comments to ask for further details or voice their opinions. The site is hilarious. Disputes range from cheating spouses to toilet flushing, oftentimes filled with more detail than anyone would want to know.
MyAWOL Becomes LP33.TV, Launches IMDB For Musicians
Jason Kincaid Fri, 05 Sep 2008 20:35:19 -0000
Last July I wrote about MyAWOL, a web-centric music label looking to compete with traditional labels, which are becoming increasingly less relevant as artists turn to digital distribution methods to gain exposure. While the site has the potential to break some new ground in the online music world, it has run into a major snag during its buildup to launch: its name sounds almost exactly like My.AOL when spoken aloud. In light of this, the company has decided to rename the site to LP33.TV, which should hopefully be less confusing. LP33 is more memorable, but I think the company should consider dropping the .TV extension entirely since they already own the .com. Along with the name change, LP33.TV is also launching its database for music industry professionals, TheMIDB, which hopes to fulfill the same role as the movie and television industry's popular IMDB. The derivative name will probably confuse just about everyone, but at least it makes the site's purpose clear.
Tatango Opens Their Group SMS Service To The Public
Greg Kumparak Fri, 05 Sep 2008 19:35:06 -0000
Tatango, the ad-supported group SMS service previously known as networkText, spent the last few months in a private beta following a functional and visual overhaul and a round of funding by Bellingham Angel Organization. Now everyone is free to get in on the group texting good times; they’ve opened the doors to the public. The service is dead simple to use, as it should be. I made the jump from accountless bum to en masse messaging mogul in all of about 2 minutes.
Google’s Picasa Moves Onto Flickr’s Turf: Adds Ways To Explore Interesting Public Photos
Erick Schonfeld Fri, 05 Sep 2008 19:21:40 -0000
On the heels of a major upgrade earlier this week that added facial recognition and video-editing features to its Picasa photo management service, Google added a new Explore page today that shows off the most popular public photos uploaded by members. In addition to the featured photos, shown in a 3 X 4 grid, the Explore page also shows the most recent photos uploaded in a slide-show widget. Below, it offers a list of the most popular tags. For instance, here are pictures tagged "New York." The Picasa Explore page also has a Where In The World? game that is mashup opf geotagged photos and Google Maps. It shows you a photo and you have to guess where it was taken. If you guess wrong, it tells you how far off you are in kilometers. This is fun for outdoor photos, but when people upload geotagged photos of a generic apartment of a plate of food, it can become tricky.

James Surowiecki: What drives market volatility?

American investors are frazzled. True, oil prices have fallen from their most vertiginous highs, the dollar is a bit stronger, and the stock market has actually risen over the past month.

The world is poorer than we thought, the World Bank discoversCorrection to this articleIN APRIL 2007 the World Bank announced that 986m people worldwide suffered from extreme poverty—the first time its count had dropped below 1 billion.

Who runs the world?: Wrestling for influence
Thu, 03 Jul 2008 13:02:45 -0000
The post-war global institutions have largely worked well. But rising countries and growing threats are challenging their pre-eminence THE powerful, like the victorious, do not just write history. They grab the seats at the top tables, from the United Nations Security Council to the boards of the big international economic and financial institutions. They collude behind closed doors. They decide who can join their cosy clubs and expect the rest of the world to obey the instructions they hand down. That is how many outsiders, not just in the poor world, will see the summit that takes place from July 7th to 9th of the G8, the closest the world has to an informal (ie, self-appointed) steering group. Leaders of seven of the world’s richest democracies, plus oil-and gas-fired Russia, gather this year in Toyako, on Hokkaido in northern Japan, to ruminate on climate change, rising food and energy prices, and the best way to combat global scourges from disease to nuclear proliferation. ...
International government: What a way to run the world
Thu, 03 Jul 2008 13:02:45 -0000
Global institutions are an outdated muddle; the rise of Asia makes their reform a priority for the WestCLUBS are all too often full of people prattling on about things they no longer know about. On July 7th the leaders of the group that allegedly runs the world—the G7 democracies plus Russia—gather in Japan to review the world economy. But what is the point of their discussing the oil price without Saudi Arabia, the world’s biggest producer? Or waffling about the dollar without China, which holds so many American Treasury bills? Or slapping sanctions on Robert Mugabe, with no African present? Or talking about global warming, AIDS or inflation without anybody from the emerging world? Cigar smoke and ignorance are in the air.The G8 is not the only global club that looks old and impotent (see article). The UN Security Council has told Iran to stop enriching uranium, without much effect. The nuclear non-proliferation regime is in tatters. The International Monetary Fund (IMF), the fireman in previous financial crises, has been a bystander during the credit crunch. The World Trade Organisation’s Doha round is stuck. Of course, some bodies, such as the venerable Bank for International Settlements (see article), still do a fine job. But as global problems proliferate and information whips round the world ever faster, the organisational response looks ever shabbier, slower and feebler. The world’s governing bodies need to change. ...
