[Q]: Article: Snapshots, the new fashion for an artistic portrait photo: Take it underwater. Zhang Xiaomei, a 20 something Shanghai native who works in the media industry, tried it out twice. "It was a completely different experience," says Zhang of her first such experience last May. "You get the feeling that you're cut off from the rest of the world. But also it s romantic and like a fairy tale." She then successfully convinced her husband to be to have their wedding photos taken underwater a couple of months after her first try. "Can you imagine a 1.87-meter-tall man trying out something like a fishtail under the water?" Zhang says, laughing. A commercial underwater photo portrait is perfect for post 80 and post 90 generations who adore taking snapshots, but are looking for new ways to be artistic, says Ai Cheng, owner and photographer of No.55 Underwater Photography in Shanghai. Ai opened a studio in Shanghai's suburb of Songjiang two years ago, building a 5-meter- deep, fan-shaped pool equipped with heating facilities to start up the business. A 30-minute training on how to smile under the water so that you won't drink too much water and how to open your eyes underwater is offered in his studio for those who don't know how to swim. Ai says most of his customers are female--half of them coming for an artistic portrait photo and the rest for wedding pictures. "Some of them drag their boyfriends or husband-to-be, who are unwilling to go down to the water, to shoot as well," he says.

[Q]: Article: Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin . Although known as the love hormone, it affects the sexes differently. "Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status," said Professor Ryan. Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction such as falling in love or giving birth. But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy. Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants received oxytocin. The other half received placebo . [( )] [( :Love my Dog.)] After a week, the two groups switched with participants. They went through the same procedure with the other material. Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions. The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better. Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factor that are mainly hormonal."

[Q]: Article: What is the relationship between violence and sports? Psychologists say that there are many reasons for violence at sports events. One is alcohol. Many fans drink a lot at games. When people drink, they are more likely to do abnormal things. Psychologist Dennis Brock says, "Quiet people become loud. Normally nonviolent people become destructive. " David Sampson, a sports sociologist, says, "These are often celebratory riots-- a large number of very happy people mixed in with large amounts of alcohol. They don't often seem dangerous in the beginning, but things get violent quickly. " Another reason for violence at sports events is the crowd. When individuals are in a large group of people, they can lose their sense of personal responsibility. Edward Hirt, a social Psychologist, says that research shows that people do things in crowds that they would never do alone. People in crowds feel anonymous -- no one knows who they are. Crowds also make people feel powerful. They stop making personal decisions. They just follow the crowd. Social psychologists call this a "mob mentality." Dave Zarifis, head of public safety says, "Some people don't even come to celebrate. They want to drink hard and make trouble. Someone does something stupid, and it grows from there. You get a mob mentality. People think it's OK to do almost anything. They think, 'There are so many of us and not enough of them. ' " Social psychologist Dr. Sharon Kennedy says that there are some things officials can do to prevent violence. Making sure that an area is not overcrowded is very important. Officials should also think of games as "big parties." Then they will prepare differently. Kennedy says that in Great Britain they are controlling the problem with cameras in all the stadiums. "When you know someone is watching, you are much less likely to behave badly. "
