Q: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Q: Article: TOKYO-- At first glance, Japanese cellphones are young people's favorites, with elegant design and quick access to the Internet. However, despite years of competition in overseas markets, Japan's cellphone makers have little presence beyond the country's shores. The only Japanese cellphone maker with any meaningful global share is Sony Ericsson, and that company is a London-based joint venture between a Japanese electronics maker and a Swedish telecommunications firm. And Sony Ericsson has been hit by big losses. Its market share was just 6.3 percent in the first quarter of 2009, behind Nokia of Finland, Samsung Electronics and LG of South Korea, and Motorola of Illinois. This year, Mr Natsuno, who developed a popular wireless Internet service called i-Mode, invited some of the best minds in the field to debate how Japanese cellphones could go global. "The most amazing thing about Japan is that even the average person out there will have a very advanced phone, "said Mr Natsuno. Japan has 100 million users of advanced third-generation smart phones, twice the number of the United States, a much larger market. Many Japanese rely on their phones, not a PC, for Internet access. Indeed, Japanese cellphone makers thought they had positioned themselves to dominate the age of digital data. But they were a little too clever. In the 1990s, they set a standard for the second-generation network that was refused everywhere else. Then Japan quickly adopted a third-generation standard in 2001. However, it made Japanese phones too advanced for most markets. Several Japanese companies are now considering a push into overseas markets, including NEC. Panasonic, Sharp, Toshiba and Fujitsu are said to be planning similar moves. "Japanese cellphone makers need to either look overseas, or exit the business", said Kenshi Tazaki, a managing vice president at the consulting firm Gartner Japan.
