Ideas about polite behavior are different from one culture to another. Some societies, such as America and Australia, for example, are mobile and very open. People here change jobs and move houses quite often. As a result, they have a lot of relationships that often last only a short time, and they need to get to know people quickly. So it's normal to have friendly conversations with people that they have just met, and you can talk about things that other cultures would regard as personal.

    On the other hand, there are more crowded and less mobile societies where long–term relationships are more important. A Malaysian or Mexican business person, for example, will want to get to know you very well before he or she feels happy to start business. But when you do get to know each other, the relationship becomes much deeper than it would in a mobile society.

    To Americans, both Europeans and Asians seem cool and formal at first. On the other hand, as a passenger from a less mobile society puts it, it's no fun spending several hours next to a stranger who wants to tell you all about his or her life and asks you all sorts of questions that you don't want to answer.

    Cross-cultural differences aren't just a problem for travelers, but also for the flights that carry them. All flights want to provide the best service, but ideas about good service are different from place to place. This can be seen most clearly in the way that problems are dealt with.

    Some societies have “universalist” cultures. These societies strongly respect rules, and they treat every person and situation in basically the same way.

     “Particularist” societies, on the other hand, also have rules, but they are less important than the society's unwritten ideas about what is right or wrong for a particular situation or a particular person. So the normal rules are changed to fit the needs of the situation or the importance of the person.

    This difference can cause problems. A traveler from a particularist society, India, is checking in for a flight in Germany, a country which has a universalist culture. The Indian traveler has too much luggage, but he explains that he has been away from home for a long time and the suitcases are full of presents for his family. He expects that the check–in official will understand his problem and will change the rules for him. The check–in official explains that if he was allowed to have too much luggage, it wouldn't be fair to the other passengers. But the traveler thinks this is unfair, because the other passengers don't have his problem.

    Most dog owners believe their dogs experience guilt, but animal behaviorists say the "guilty look" of a dog is simply a reaction to you and that dogs lack the ability to feel shame.

    Alexandra Horowitz, a psychology professor and principal investigator at the Horowitz Dog Cognition Lab at Columbia University once carried out a study on dog "guilt". She videotaped 14 dogs in a series of trials and observed how they reacted when their owners left the room after instructing them not to eat a treat. When the owner was gone, Horowitz gave some of the dogs the forbidden treat. Then she would tell the owners whether their dogs had eaten the treat or had behaved. However, Horowitz wasn't always honest with them.

    Horowitz found that the dogs' "guilty looks" had little to do with whether they'd eaten the treat or not. In fact, dogs that hadn't eaten it but were scolded by misinformed owners tended to exhibit the most elements of the "guilty look".

Horowitz says this shows that the dogs' body language is actually a response to their owner's behavior—not an experience of shame for a misdeed. Why then, do dogs look so ashamed when we scold them?

Maybe that look of guilt is the result of a learned association. When you scold your dog for chewing up a pair of slippers, he quickly learns that if he lowers his head and tucks his tail, the undesirable response—raised voice and angry expression—is more likely to disappear.

    When men get together, they seldom talk about their feelings or inner thoughts. However, they talk about a lot, like their newest computer, how to repair their car, or even business.

    Talk might move to the best place to find fish or women, jump to computer games, then continue to the sport of the season. They also like to tell jokes each other and spend a fair amount of time playing one-up and boasting (吹牛). Men seldom call each other to chat.

    When man meets woman, he usually wants to make a good impression. Many single men try hard to carry on amusing, fun, and pleasant conversations. They use conversation to discover her interests and feelings in order to learn how to be attractive to her.

    Some men, either out of nervousness or ignorance, spend most of the time talking about themselves, often appearing to brag about their achievements or talk endlessly about their problems or work. Even the quietest man talks to his woman when love is new.

    When women get together, they talk about feelings and relationships, their work and their family. They enjoy talking but also want the give and take of talk, then listen. Women often call each other to chat. Conversation is an important part of most women's 1ives.

    As relationships progress, however, many a man turns on the television and forgets how to talk. This raises anger and cry from his woman partner who says, “You never talk to me anymore.” Some men start talking. Many, however, mainly discuss their own achievements and problems.

    When the woman starts talking about her favorite subjects: feelings, family, relationships, friends and her work, many men lose interest or bring the conversation back to themselves. Pretty soon, the man is back to staring at the television each night, wondering where his relationship has gone. The woman is talking to her friends, mom, sister, or neighbor, often about that very relationship and how she is hurting.

    Tencent announced yesterday that it will limit the daily time for youngsters to play its popular King of Glory game after parents and schools in Shanghai and other areas complained their children had become addicted to playing it.

    From tomorrow, children younger than 12 will only be allowed to play the game for a maximum(最大值) of one hour a day, and after 9 pm, they will be banned from logging into it, said Tencent. Those older than 12 will be able to play a maximum two hours a day.

    The game system will remind players the time they have been playing and young players will be forced to log out when the time is up.

    Tencent claimed these were the strictest measures in China's game industry to prevent addiction and the company expected they would ease parents' anxiety.

    The company also said it had updated its system for parents to keep tabs on their children using its games.

    Since February, parents can receive messages when children log in and spend money on the game after they connect children's game accounts with their mobile phone numbers.

    Now, parents can connect phones, tablets or computers that their children use to play games, so that they can keep an eye on the children even if they have several game accounts, Tencent said.

    Song Zhe, a father of a Shanghai high school student, welcomed the measures but was not sure if they would be sufficiently effective. "I like the system that could lock up the devices as children can register many accounts," he said, "but children are so clever that they can always think out counter measures."

    The recession (衰退) of 2008-09 was remarkable in rich countries for its intensity, the following recovery for its weakness. The labour market has also broken the rules, as new research from the OECD, a think-tank of mainly rich countries, shows in its annual Employment Outlook.

    Young people always suffer in recessions. Employers stop hiring them; and they often get rid of new recruits because they are easier to dismiss. But in previous episodes, such as the recessions of the 1970s, 1980s and 1990s, older workers were also kicked off. This time is different. During the financial crisis in 2008, and since, they have done better than other age groups.

    The researchers focus on movements in "non-employment" as a share of the total population in three age groups between the final quarters of 2007 and 2012. This measure has the advantage of including not just unemployment, where people are looking for work, but also inactivity, where people are not seeking jobs. Whereas the average non-employment rate in the OECD has risen by four percentage points among young people and by one-and-a-half points among 25-to 54-year-olds, it has fallen by two points among the 55-64 age group.

    Why have older employees done so well? In some southern European countries they benefit from job protection not afforded to younger workers, but that did not really help them in past recessions. What has changed, says Stefano Scarpetta, head of the OECD's employment directorate, is that firms now bear the full costs of getting rid of older staff. In the past, early-retirement policies provided by governments (in the mistaken belief that these would help young people) made it cheaper to push grey-haired workers out of the door. These have largely stopped.

    Many will argue that older workers have done better at the expense of the young. That view is wrongheaded. First, it is a fallacy that a job gained for one person is a job lost for another; there is no fixed amount of work. And second, as the report shows, young and old people are by and large not substitutes in the workplace. They do different types of work in different types of occupation: younger people are keen on IT firms, for example, whereas older folk tend to be employed in more traditional industries. There are plenty of things that should be done to help the young jobless, but kicking older workers out of the workplace is not one of them.
