In agrarian(农业的), pre-industrial Europe,“you'd want to wake up early, start working with the sunrise, have a break to have the largest meal, and then you'd go back to work,”says Ken Albala, a professor of history at the University of the Pacific.“Later, at 5 or 6, you'd have a smaller supper.”

    This comfortable cycle, in which the rhythms of the day helped shape the rhythms of the meals, gave rise to the custom of the large midday meal, eaten with the extended family.“Meals are the foundation of the family,”says Carole Couniban, a professor at Millersville University in Pennsylvania, “so there was a very important interconnection between eating together and strengthening family ties.”

    Since industrialization, maintaining such a slow cultural metabolism has been much harder, with the long midday meal shrinking to whatever could be stuffed into a lunch bucket or bought at a food stand. Certainly, there were benefits. Modern techniques for producing and shipping food led to greater variety and quantity, including a tremendous increase in the amount of animal protein and dairy products available, making us more energetic than our ancestors.

    Yet plenty has been lost too, even in cultures that still live to eat. Take Italy. It's no secret that the Mediterranean diet is healthy, but it was also a joy to prepare and eat. Italians, says Counihan, traditionally began the day with a small meal. The big meal came at around 1 p.m. In between the midday meal and a late, smaller dinner came a small snack. Today, when time zones have less and less meaning, there is little tolerance for offices' closing for lunch, and worsening traffic in cities means workers can't make it home and back fast enough anyway. So the formerly small supper after sundown becomes the big meal of the day, the only one at which the family has a chance to get together.“The evening meal carries the full burden that used to be spread over two meals,”says Counihan.

In a new move, doctors are using feature films in order to encourage their patients to talk more freely about their problems. Supporters of "film therapy (疗法)" say that discussing characters and plot lines from a proper film can help people to understand their feelings better.

One of those using the method is Bernie Wooder, a doctor from Elstree, who charges £45 for a one-hour "film therapy" session. He said, "I was treating a woman who had been badly let down in a relationship, and who was experiencing such strong feelings that it was difficult for her to speak about them. I told her that her situation reminded me of On the Waterfront, when Marlon Brando's character realizes his brother is dishonest and he feels a great sense of betrayal (背叛). My patient identified so easily with him that she started to cry. Watching and discussing the film unlocked all the feelings she had buried. Each time she watched and cried, she felt better."

Mr Wooder admits that film therapy does not work for everyone, but says he has used it successfully with about a third of his clients. "Through the films' characters, plots and even music, it allows people to face their problems." He said that Falling Down, in which Michael Douglas plays the part of an unemployed man who is so frustrated (沮丧的) that he uses violence, was an example of the dangerous implications (后果) of not letting anger go. "I used this film with a patient who was very upset because he was holding on to a lot of the anger he felt towards people who had frustrated him," said Mr Wooder. "We talked about Michael Douglas's character and the disastrous path he takes, and my patient then realized that he needed to let go of his feelings more regularly so as not to erupt (爆发) like a time bomb."

    Japan is very serious about robotics (机器人技术). If robots are going to fit in, they probably need to learn the Japanese custom of serving tea. Fortunately, researchers at the University of Tokyo are just exploring that. In a show this week, a humanoid(人形机器人)with camera eyes made by Kawada Industries Inc. poured tea from a bottle into a cup. Then another robot on wheels delivered the cup of tea in an experimental room that has sensors embedded in the floor and sofa as well as cameras on the ceiling, to simulate(模仿)life with robot technology.

    "A human being may be faster, but you'd have to say ‘Thank you'," said Professor Tomomasa Sato from the University of Tokyo. "That's the best part about a robot. You don't have to feel bad about asking it to do things."

    Sato believes Japan, a rapidly aging society where more than a fifth of the population is 65 or older, will lead the world in designing robots to care for the elderly, sick and bedridden(长期卧床的).

    Already, monitoring technologies, such as sensors that automatically turn on lights when people enter a room, are becoming widespread in Japan.

    The walking, child-size Asimo from Honda Motor Co. greets people at show-rooms. NEC Corp. has developed a smaller robot-on-wheels companion called Papero. A seal robot available since 2004 can entertain the elderly and others in need of fuzzy companionship.

    Sato says his experimental room is raising awareness about privacy questions that may arise when electronic devices(设备)monitor a person's movements down to the smallest detail.

    On the bright side, the tea-pouring humanoid has been programmed to do the dishes.

                                                  Printable Tags Turn Everyday Objects into Smart Devices

    Engineers have developed printable metal tags (标签)that could be attached to everyday objects and turn them into smart Internet of Things devices.

    The metal tags are made from copper foil (铜箔) printed onto thin, flexible, paper-like materials to reflect WiFi signals. The tags work essentially like "mirrors" that reflect radio signals from a WiFi router(路由器). When a user's finger touches these "mirrors", it disturbs the reflected WiFi signals in such a way that can be remotely sensed by a WiFi receiver like a smartphone.

    The tags can be nailed onto objects that people touch every day, like water bottles, walls or doors. These objects then become smart and connected devices that can signal a WiFi device whenever a user interacts with them. The tags can also be shaped into thin keypads or smart home control panels that can be used to remotely operate WiFi-connected speakers and other Internet of Things devices.

    Xinyu Zhang, a professor of electrical and computer engineering, named the technology LiveTag. He pictures people using LiveTag technology to track human interaction with everyday objects. For example, LiveTag could potentially be used to assess the recovery of patients who have suffered from stroke (中风). "When patients return home, they could use this technology to provide data based on how they interact with everyday objects at home, whether they are opening or closing doors in a normal way, or if they are able to pick up bottles of water, for example. The amount, intensity and frequency of their activities could be recorded and sent to their doctors to evaluate their recovery," said Zhang. "And this can all be done in the comfort of their own homes rather than having to keep going back to the clinic for frequent testing," he added.

    The researchers note several limitations of the technology. LiveTag currently cannot work with a WiFi receiver further than one meter away, so researchers are working on improving the tag sensitivity and detection range. Ultimately, the team aims to develop a way to make the tags using normal paper and ink printing, which would make them cheaper to mass produce.

    Working or learning in a foreign country can be a difficult experience. The hardest part of working abroad isn't finding a place to stay or learning the language. It's learning to overcome the culture shock.

    These things are part of everyday life, and include many signs, gestures, facial expressions, and customs. When we enter a new culture, these cues (提示)are usually not present or so different that they're no longer understandable to us.

    "When a person enters a foreign culture," wrote Oberg, "all or most of these familiar cues are eliminated. He or she is like a fish out of water. No matter how broad-minded he or she may be, lots of props(支柱) have been knocked out from the environment."

    This is what happened to Lara, a young IT consultant (顾问) from America moved last year to their company in southern Europe. Three weeks after she arrived in Europe. Lara sent a desperate e-mail begging to return home. "The people are so unfriendly, "Lara wrote ,"They eat at strange hours and I'm starting to get allergic (过敏的)to the local food. I can't get anything done because their way of doing business is so disorganized and so inefficient and I have a terrible skin itch because of the water. I want to come home! "

    What Lara and other IT consultants meet on their first assignment abroad is a culture shock. While you can't prevent the culture shock from happening, you can take some measures to cut down its effects.
