Business administration is the most popular undergraduate major in U.S. colleges and universities, accounting for as much as one-fifth of all bachelor degrees awarded each year. Students naturally think of a business degree as the surest way to land a good job after graduation. Many international students agree. Twenty percent studied business last year-the second most popular major after engineering, according to the Institute of International Education.

    Below are descriptions of three of U.S. colleges and universities with strong offerings in business.

    Bentley College    Waltham, Massachusetts

    Bentley offers its 4,000 undergraduates a top-flight business education and an equally strong liberal-arts program that leaves them well-prepared to join the ranks of future business leaders. The college occupies a scenic campus only a shuttle-bus ride from Boston's Harvard Square. More than 90 percent of students seek career-oriented internships（实习）.

    Bucknell University    Lewisburg, Pennsylvania

    Bucknell's 3,500 undergraduates benefit from small classes and an engaging staff at this liberal-arts institution in a remote but beautiful campus in central Pennsylvania. Accounting and financial management are specialties in the introductory management course that create and sell a product and then donate their profits to charity（慈善）.

    University of Cincinnati        Cincinnati, Ohio

    This urban university with 21,000 undergraduates, located a mile from downtown Cincinnati, was the-birthplace of cooperative education over a century ago. Under this five-year “earn while you learn” program, more than 3,000 students alternate academic study with internships in local businesses and other organizations.

    If you analyze people's actions, you will come to the conclusion that they all seek happiness. Every act is in fact a search for it, even if on the surface it doesn't look so. Happiness is always the main target.

    Going to the movies, eating in a restaurant and going to a party are all motivated by the desire to be happy. Who does not dream of a vacation in some fascinating locations, a new car, a new house, or the ideal match? All people daydream, and some even try to make their dream a reality. And why is that? In order to be happy!

    Many people endanger themselves by climbing steep mountains, entering unexplored caves, or diving into the deep of the ocean in order to enjoy the few moments of happiness. A thief may steal because he loves the thrill of danger, or because he desires to have quick money to spend. He is actually looking for happiness, though in a perverted way.

    Of course not all actions end in happiness. The motive is happiness, but the results do not always bring the desire. According to some spiritual traditions, we are spiritual beings in physical bodies. The spiritual part is always happy. Rather, it is happiness itself. But the physical body covers this happiness essence(本质). There is a constant desire to find out this happiness. This is the reason why happiness is constantly sought.

    However, there is no need to search for happiness or to create it, or to have all kinds of outer experiences and actions in order to feel it. On the contrary, everything has to be dropped in order to experience it. Every technique, which helps to relax the mind and calm the rush of thoughts will lead to happiness.

    My wife and I went to this vegan(严格的素食主义的)restaurant to give it a try.As we were eating our pepper and salt tofu, a young lady named Debra walked in. She wasn't aware that the place is vegan and was looking for some meat. My wife and I talked up the place and invited her over to try some of our tofu. Debra tried it, nodded and went out.

    After a few minutes, she and her mother both walked back in. We were having the rest of our meal at that time, so we told her what we had ordered. Debra then asked the waitress to just repeat our order for them. Next, Debra said, "And we want to pay for their meal", pointing to my wife and me. We tried to say no, but Debra wouldn't listen.

    That was not the end of it. Hugs were in order. Debra came over to our table and my wife got up to hug her. Debra hugged my wife and put $100 into her hand. My wife firmly said NO, but Debra insisted. Debra kept talking about our kindness, and we did the same about hers and her mother's. With tears in the eyes, the workers were blown away by this whole exchange between four strangers. I left the waiters a tip that would cover all of our meals and we were on our way.

    I've been witnessing so much kindness, especially over the last few years, as I began to pay more attention. We now have a new favorite restaurant and every time we go there my plan is to pay for someone else's meal.

    The annual World Economic Forum took place in Davos, Switzerland, in Jan. 23-26, 2018. What did Chinese entrepreneurs （企业家）speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

    "I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve (结束) the war not cause the war," said Ma in Davos, "Google, Facebook, Amazon and Alibaba — we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good."

    Richard Liu, founder and chief executive officer of JD

    "Business is not only a way to make money but also a way to contribute yourself, to help people," Liu said in a speech in Davos. "How can we face the fractured (分化的) world? That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, if we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners," he said.

    Jane Sun, CEO of Ctrip

    "Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming." Sun told Sina.com in Davos. "We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity," she said.

    Hu Xiaoming, president of Aliyun

    "In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use ‘cloud', and cloud computing will increase the efficiency of technology and finance," Hu told Xinhua in Davos.

    Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is trustworthy? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.

    The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guilt-proneness (内疚倾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given $1, which they can choose to give to Player2. Any money given to Player 2 is then automatically increased to $2.50. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a portion of the money to Player 1. The researchers found more guilt-prone people were more likely to share the money with Player 1. Actually, in follow-up studies, guilt-proneness predicted trustworthiness better than other personality qualities the researchers measured.

    Why might guilt lead to trustworthy behavior? The researchers found people who were guilt-prone also reported feeling an obligation to act in ethical (合乎道德的) and responsible ways while interacting (互动) with their partners in the game. People who are guilt-prone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again.

    Then, how can we use this research to ascertain whether someone is trustworthy? "One way to do this might be observe how they respond to experience regret," lead author Emma Levine, assistant professor at the University of Chicago Levine, explains. Another way is to ask them to describe a difficult dilemma they faced in the past, suggests co-author Taya Cohen, associate professor at Carnegie Mellon University. This is particularly effective, Cohen and her colleagues have found, because it allows us to see if they're concerned about the effects their actions have on others.

Accines (疫苗) may soon make their first film appearance. Led by expert Maria A. Croyle, researchers have developed a thin sheet that preserves vaccines for long periods without refrigeration. This means the carefully cooled small bottles now used to ship vaccines could potentially be replaced by lightweight films that can be mailed in an envelope and stored on a shelf.

Croyle's laboratory began developing the technology in 2007. Inspired by amber's ability to preserve the DNA of insects, the researchers set out to create their own version of the substance by mixing "a lot of sugar and a little bit of salt, much like hard candy," Croyle explains. The vaccine-containing film is administered by mouth—sweet news for many who dislike needles.

The film is tailored to suit each specific vaccine candidate and provide a protective coating. "We've learned over time that the key to really stabilizing whatever the film holds is to have it intermixed with all the components," Croyle says, adding that the process is quick and uses affordable, standard equipment. "We really wanted to come up with something that would be transferable to developing countries."

Immunization(免疫) programs depend heavily on keeping vaccines cold(2℃-8℃) as they are transported, sometimes over thousands of kilometers to far-away locations. Delivery can be difficult and costly, and transport disruptions can cause the vaccines to be ineffective.

But this new product can store live viruses, bacteria and antibodies for several months at 20℃. In a paper published in Science Advances, the scientists show that the live viruses in one vaccine were preserved in the film even after 36 months. They also find that a flu vaccine suspended in their film compares favourably with a traditional flu shot(流感预防针). "The study demonstrates early proof of concept for an exciting platform for vaccine product development," says Lisa Rohan, a pharmacologist, who was not involved in the study. She also notes that each vaccine type would need a custom formulation(配方) for future stages of development.

Finding partners to mass-produce for clinical trials is the researchers' most pressing problem, Croyle says. They are also exploring packaging methods to keep their films stable up to 40℃.

Size is a major advantage—a letter-sized sheet of the film can carry more than 500 doses(剂) of vaccine, about 1⁄900 the weight of the same amount of traditional doses. By making it easier and cheaper to ship and preserve vaccines efficiently, Croyle says, the technology could vastly improve immunization rates the world over, particularly in middle- to low- income countries.
