Amid all the job losses, there's one category of worker that the economic disruption has been good for nonhumans. From self-service checkout lines at the supermarket to industrial robots armed with saws and taught to carve up animal bodies in slaughter-houses, these ever-more-intelligent machines are now not just assisting workers but actually kicking them out of their jobs. Automation isn't just affecting factory workers, either. Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly-paid human lawyers. "Robots continue to have an impact on blue-collar jobs, and white-collar jobs are under attack by micro-processors," says economics professor Edward Learner. The recession permanently wiped out 2.5 million jobs. U. S. gross domestic product has climbed back to pre-recession levels, meaning we're producing as much as before, only with 6% fewer workers. To be sure, robotics are not the only job killers out there, with outsourcing(外包) stealing far more jobs than automation. Jeff Burnstein, president of the Robotics Industry Association, argues that robots actually save U. S. jobs. His logic: companies that embrace automation might use fewer workers, but that's still better than firing everyone and moving the work overseas. It's not that robots are cheaper than humans, though often they are. It's that they're better. "In some cases the quality requirements are so exacting that even if you wanted to have a human do the job, you couldn't," Burnstein says. Same goes for surgeons, who're using robotic systems to perform an ever-growing list of operations—not because the machines save money but because , thanks to the greater precision of robots, the patients recover in less time and have fewer complications, says Dr. Myriam Curet. Surgeons may survive the robot invasion, but others at the hospital might not be so lucky, as iRobot, maker of the Roomba, a robot vacuum cleaner, has been showing off Ava, which could be used as a messenger in a hospital. And once you're home, recovering, Ava could let you talk to your doctor, so there's no need to send someone to your house. That "mobile telepresence" could be useful at the office. If you're away on a trip, you can still attend a meeting. Just connect via videoconferencing software, so your face appears on Ava's screen. Is any job safe? I was hoping to say "journalist", but researchers are already developing software that can gather facts and write a news story. Which means that a few years from now, a robot could be writing this column. And who will read it? Well, there might be a lot of us hanging around with lots of free time on our hands.

中国书法 (Chinese calligraphy)是汉字的书写艺术,旨在在汉字的书写过程中体现线条和布局的美感。书法在中国古代具有重要的实用功能,是所有知识分子都必须掌握的技能,因此出现了大量优秀的 书法家 (calligrapher)与 书法作品 (calligraphic work)。此外,书法作为一门成熟的艺术,有一套完整的创作、鉴赏、收藏理论体系,并与中国绘画、雕刻、舞蹈、音乐等艺术相互影响。汉字的书法艺术不仅盛行于中国,也传播到了日本、朝鲜等国,被视为东亚的重要艺术和最优雅的写字形式之一。

A recent case in Australia shows how easily fear can frustrate an informant's good intentions. In December, a woman wrote anonymously to the country's antitrust watchdog, the ACCC, alleging that her employer was colluding with others in breach of the Trade Practices Act. Her evidence was sufficient to suggest to the ACCC that fines of A$10m could be imposed on "a large company". But the agency needed more details. So just before Christmas it advertised extensively to try and persuade the woman to come forward again. Some days later her husband rang the ACCC, but he hung up before disclosing vital information. Now the agency is trying to contact the couple again. In America, there is some evidence that the events of September 11th have made people more public-spirited and more inclined to blow the whistle. The Government Accountability Project, a Washington-based group, received 27 reproaches from potential informants in the three months before September 11th, and 66 in the three months after. Many of these complaints were about security issues. They included a Federal Aviation Adnunistration employee who claimed that the agency had repeatedly failed to respond to known cases of security violations at airports. Legislation to give greater protection to people who expose corporate or government misbehavior externally(after having received no satisfaction internally)is being introduced in a number of countries. In America, it focuses on informants among federal employees. According to Billy Garde, a lawyer who was a member of BP's Alaska inquiry team, they "have less rights than prisoners". A bill introduced last year by Senator Daniel Akaka to improve protection for them is currently stuck in congressional committees. In Britain, the Public Interest Disclosure Act came fully into force last year. Described by one American as "the most far-reaching informant protection in the world", it treats informants as witnesses acting in the public interest. This separates them from people who are merely pursuing a personal grievance. But even in Britain, the protection is limited. Rupert Walker, a fund manager, was fired by Govett Investments in September 2001 for expressing concerns in the Financial Times about a group of people of investment trusts that invest in each other.

I live in the land of Disney, Hollywood and year-round sun. You may think people in such a glamorous, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness. Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what experience during an act. Happiness is what we experience after an act. It is a deeper, more abiding emotion. Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends. I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to glamorous parties, fancy cars, and expensive homes, everything that spells "happiness". But in memoir after memoir, celebrities reveal the unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages, troubled children and profound loneliness. Ask a bachelor why he resists marriage even he finds dating to be less and less satisfying. If he' s honest, he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they are not its distinguishing features. Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out ever they want and sleep as late as they want. Couples with infant children are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those rich and glamorous people we were so sure are happy because they are always having so much fun actually may not be happy at all.
