According to a recent study out of the University of Pennsylvania's Wharton School, men with shaved heads are considered to be more manly, powerful, and successful than those with longer hair or thinning(稀少的) hair. Besides, in some cases, they are considered to have greater leadership potential (潜力). That may explain why the power-buzz look has become popular among business leaders in recent years.

    Albert Mannes, Wharton management lecturer, said he was encouraged to do the research after noticing that he was treated with more respect when he shaved off his thinning hair.

    Mannes did three experiments to test people's impression of men with shaved heads. In one of the experiments, he showed 344 subject photos of the same men in two versions: one showing the men with hair and the other showing them with their hair digitally removed, so their heads appear shaved. In all three tests, the subject report found the men with shaved heads are more dominant(占优势的) than their hairy counterparts(对应的人).

    The study found that men with thinning hair were viewed as the least attractive and powerful. For those men, the solution could be as cheap and simple as a shave.

    New York image consultant Julie Rath advised her clients to get closely cropped when they start thinning up top. “There is something really strong, powerful and confident about laying it all bare(光秃的),” she said, describing the thinning look as kind of raunchy(不修边幅的).

    Not everyone needs a bare head. Rick Devine, 55, the CEO of Devine Capital Partners, advised executive candidates attracted by their clippers to keep their hair closely cropped, rather than completely shaved. “It is way too much image risk,” he said, “The best thing you can do in a business meeting is to make your look not an issue.”

    It's a sadness shared by many business start-ups: why did my company fail, while so many others seem to be profiting from the “golden age of entrepreneurship (创业精神）”？

    Some people argue that opportunities and good fortune are the secrets to success. But Innovation Works CEO Kaifu Lee believes that entrepreneurs need to have certain qualities to help them face the difficulties of starting a business. At a recent LinkedIn conference, Lee mentioned some of these qualities.

    “Even though we're now in a golden period for innovation and start-ups, not everyone is meant to be an entrepre- neur. Entrepreneurs share the same qualities — they are confident, communicative and focused. They don't fear losing, and they are good at learning,”he said.

    Lee explained that he often meets young people who are irresolute about setting up a business.“ If that's the case for you then don't do so,” he said at the conference. The bottom line, he said, is that entrepreneurs should be determined and passionate.

    Passion is vital to entrepreneurs since it typically relates to self-motivation, according to Li Jun, 26, founder of Wuhan Lushenglin Plant Wall Co Ltd. “Entrepreneurs often need to work around the clock. It's easier for people to put up with the difficult schedule if they're passionate about what they're doing,” he said.

    Entrepreneurs are also generally thought of as risk-takers. But Yu Xiuhong, general secretary of the Bright China foundation, warns that young entrepreneurs should not take too many risks. “Successful entrepreneurs rarely take risks blindly or jump at opportunities others avoid. Before launching a business, it's advisable to do market research, evaluate yourself and your opponents,” she said.

    Also she advises that young people thoroughly calculate their expenses in advance. Take Li Dongjin as an example, 35-year-old long-term entrepreneur disappeared a week ago after his O2O car washing company failed disastrously. He had gotten an initial investment of 5 million yuan but wasted it all on allowance and publicity.

Dear Derrick ,

    Although under great pressure, we all get on well with each other in this large office. You are one of the people who keep the social temperature at such a comfortable setting. I don't know anyone in the office who is better liked than you .

    You can perhaps help with this. The collection of contributions towards gifts for employees' personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two weeding gifts, one funeral remembrance, four birthday gifts, and three graduation gifts .

    It's not only the collected-from who are growing uncomfortable(and poor), but the collected-for feel uneasy receiving gifts from people who don't know them outside the office, who wouldn't even recognize their graduating children, their marrying daughters and sons, or their dead relatives.

    This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today's office setting .

    Thank you for understanding .

    An old friend from California called from the airport to tell me that he had arrived. I was not able to leave the office, but I had made plans for his arrival. After explaining (解释) where my new house was, I told him that I had left the key under the doormat (门垫). Since I knew it would be pretty late before I could get home, I suggested that he make himself at home and help himself to anything that was in the refrigerator(电冰箱).

    Two hours later my friend phoned me from the house. At the moment, he said, he was listening to some of my records after having had a delicious meal. Now, he said, he was drinking a glass of orange juice. When I asked him if he had had any difficulty finding the house, he answered that the only problem was that he had not been able to find the key under the doormat, but luckily, the living room window by the apple tree had been left open and he had climbed in through the window. I listened to all this in great surprise. There is no apple tree outside my window, but there is one by the living room window of my next door neighbor's house!

    I was waiting for my train and on the subway station's floor was a man just sitting there. I looked around and nobody stopped so I just went my way. After a few steps, I turned and asked him whether he needed help. He told me his house was one station further and he would only need to take the train there. So I reached for his hand to help him stand up.

    He wanted to take the stairs but I feared that he would hurt himself since he seemed too weak to walk, so I asked him to take the elevator. Even though my mind was trying to turn the danger lights on, I put the thought that I should not go alone with a drunken man out of my mind and accompanied him on the elevator.

    We arrived on the platform with no incidents. The man's knees seemed to soften, so I asked him to rest on a bench. While sitting there, he thanked me, telling me that I saved him. No, I said, I really did nothing; he saved himself as he walked on his own feet.

    At the next station, we said our goodbyes. Before I knew it, he left 100 dollars and dashed out of the train. There was no way to give him back his money. I wanted to leave it on the seat, but a young woman who thought it belonged to me ran after me and gave me the note.

    My initial reaction to getting that money was of shame and I even felt offended. Then I thought he just wanted to thank me, the best way he knew how. Now, my question is — what act of kindness shall I do with these 100 dollars?

Western monarch butterflies(帝王蝶)spend their winters on the central California coast. A few months later, they produce young in the Central Valley and as far north and east as Idaho. But where they go in between remains an open question to biologists. Therefore, a group of biologists call on anyone who spots a monarch north of Santa Barbara this spring to get a quick shot(镜头)and email them the photo with a date and a location.

"Something's going on in early spring," said Cheryl Schultz, a professor at Washington State University Vancouver. "Winter survival isn't the problem in the short term, but they don't know whether the monarchs are not making it producing places, not finding plants to feed themselves along the way," she said.

The Western monarch population stood in the millions in the 1980s. In 2017, an annual count found 200,000 butterflies. In 2018, the number fell to about 30, 000-a figure that held steady last year. The monarchs' decline is part of a large trend among dozens of butterfly species in the West. What exactly caused the decline? Biologists attach it to a variety of reasons. Many chemicals are sprayed on the milkweed(乳草)monarchs will feed on. Climate change also plays a role in challenges facing monarchs. Yet, they're not nearly as threatening as those leading to loss of their living room. Farms used to have rough borders that were grounds for the plants monarchs love and live in. However, newly applied practices pushed crops to the edge of fields.

"Butterflies often have good and bad years. We do think there's potential to turn the situation around." Dr. Schultz said. And she said she saw two reasons for that. First, the population decline seen in 2017 ~ 2018 wasn't repeated last year. And second, she's seen butterfly populations recover before.
