Cambridge psychologists and computer scientists have developed a mobile phone technology which can tell if a caller is happy, angry, bored or sad. The Emotion Sense technology will enable psychologists to show links between moods, location and people. It uses speech-recognition software and phone sensors attached to standard smart phones to assess how people" s emotions are influenced by day-to-day factors.The sensors analyze voice samples and then place them into 5 emotional categories: happiness, sadness, fear, anger and a neutral category(such as boredom or passivity). Scientists then cross-reference these emotions against surroundings, the time of day and the caller" s relationship with the person they are speaking to. Results from a pilot scheme revealed that callers are happier at home, sadder at work and display more intense emotions in the evenings.

问答题

The Dead Sea, shared by Israel and Jordan, is the lowest spot on Earth. Its shoreline is a-bout 400 meters below sea level. As the world s saltiest large body of water, averaging a salt content 6 times higher than that of any ocean, the Dead Sea supports no life. With no outlet, the water that flows into the Dead Sea evaporates in the hot, arid air, leaving the minerals. The Jordan River is the chief source of the incoming water, but since the 1960s much of its water has been diverted for irrigation. Its length has already shrunk by more than a third, and, while the sea will never entirely disappear due to evaporation slowing down as surface area decreases and saltiness increases, the Dead Sea as we know it could become a thing of the past.

The huge earthquake that hit off the coast of northeastern Miyagi prefecture earlier this year was a harsh reminder of the more elemental dangers that can threaten economic activity on the crowded and seismically vulnerable Japanese archipelago. Weighing the full implications of the natural disaster will take time. Yet the earthquake at the very least throws a huge question mark over an economic recovery that economists had hoped would gather steam in 2011 after stalling in the last three months of 2010. Although the areas worst hit are far less economically significant than the coastal industry zones, which suffered widespread stoppages after the 1995 Kobe earthquake, the disaster could heighten recent uncertainty among consumers and investors about the prospects for Japan s continued recovery from its worst postwar recession.Learning from the lessons of the devastating disaster in 1995, the government and insurance companies have been actively encouraging even smaller companies to draw up detailed business continuity plans intended to minimize losses and aid quick recoveries. In the longer term, the earthquake is certain to force heavy spending on construction and public works in the affected region. The terrifying footage of tsunami carrying away whole buildings makes it clear that dealing with the damage will require huge effort and heavy investment.
