PROBLEM: Article: Japanese workers who run secretly out of the office and spend their afternoons hanging around coffee shops may soon be caught out by their bosses. A new cellphonebased tracking device from Hitachi can show, on an employer's computer screen, not only the whereabouts of their workers but also whether they are standing, walking, running--or have fallen over. The system, called Partout, was originally developed as a monitoring device for the families of people with dementia, who may wander off and need to be located. "It's estimated that the number of elderly people with symptoms of dementia will reach 1.5 million in Japan next year," says Hitachi's Keisaku Shibatani. But the high cost of the system--early prices are around PS27,000--has put it out of reach of most families. Indeed, companies with large sales forces and police departments who want to track officers on dangerous patrol duties are interested in the system. Partout uses a multifunction location sensing unit that tracks users through global positioning satellites. The user's body motion is determined by an accelerometer inside the sensing unit: no movement means the subject has stopped, slow movement means they are walking, fast movement means they are running, and strong and unexpectedly sudden movement means the user may have fallen. The date is relayed through the user's cell phone to computer, which displays their position on a map. Graphics record the motion or position of the subject's body.
Answer: A new model of cell phone.

PROBLEM: Article: A board game is a game played on a pre-marked surface or "board" according to a set of rules. Board games have been played in most cultures and societies throughout history. Do you think of yourself as a bit of an expert at board games like chess or Go? Maybe you're not quite as good as you think. New research from the University of Manchester and Oxford suggests complex games like these are impossible to learn fully. They may even be too complex for the human mind to understand. Researchers studied two-player games, to try and understand the strategies which people use to make decisions during the game. Some games with two players are simple, with only a small number of possible moves. Players can quickly work out the best strategy but that means the game soon becomes boring. It gets more interesting when there are many possible moves. That's why people are so fascinated by complex board games like chess or Go, or some card games. But what the researchers found was that with difficult games, players find it hard to work out the best strategy and their actions become less reasonable. This research is part of the field called game theory: the study of human strategic decision-making. Much thinking on how people play complex games is based on something called "the balance point", which is when players have a perfect knowledge of what they are going to do and of what their rivals are going to do. When you add more than two players then of course the game becomes even harder to understand. Trading on the stock market is an example of a complex multi-player game.

PROBLEM: Article: Some say the Internet will kill off papers. Others say not so fast. Are newspapers dying? That's the heated debate these days. Many say the disappearance of the daily paper is just a matter of time. The future of journalism is in news websites, not newsprint. However, others say, newspapers have been with us for hundreds of years, and while all news may be online some day, papers can exist for some time. So who's right? I'll outline the arguments on both sides, and then you can decide. Newspapers Are Dead Newspapers are in trouble. Circulation is dropping, display and classified ad income is drying up, and the industry has experienced a hard time. Big metro papers like the Rocky Mountain News have stopped operating, and even bigger newspaper companies like the Tribune Co. go bankrupt . And where are newspaper readers going? To the Web. A recent study has found that Internet users read online newspapers for an average of 53 minutes per week in 2008. That's highest level recorded in the eight years when the study has been done. The study found that 22 percent of users said they stopped their subscription to a printed paper or magazine because they could access the same content online. Some people say the Internet is just a better place to get the news. "On the Web, newspapers are live, and they can supplement their coverage with audio, video, and the valuable resources of their vast contents," says Geffrey I. Cole, director of the Center for the Digital Future.
