At the age of ten I could not figure out what this Elvis Presley guy had that the rest of us boys did not have. I mean, he had a head, two arms and twolegs, just like the rest of us. About nine o'clock on Saturday morning I decided to ask Eugene Correthers, one of the older boys, what it wasthat made this Elvis guy so special. He told me that it was Elvis' wavy hair and the way he moved his body.

    About half an hour later all the boys in the orphanage(孤儿院) were called to the main dining-room and told we were all going to downtown Jacksonville, Florida to geta new pair of Buster Brown shoes and a haircut. That is when Igot this big idea, which hit me like a ton of bricks. If the Elvis hair cut was the big secret, then that's what I was going to get.

    All the way to town I told everybody, including the matron(女管家) from the orphanage who was taking us to town, that I was going to look just like Elvis Presley and that I would learn to move around just like he did and that I would be rich and famous one day, just like him.

    When I got my new Buster Brown shoes, I could hardly wait for my new hair cut and now that I had my new Busier Brown shoes I would be very happy to go back to the orphanage and practice being like Elvis.

    We finally arrived at the big barber shop, where they cutour hair for free because we were orphans(孤儿). I looked at the barber and said, “I want an Elvis hair cut. Can you make my hair like Elvis?”I asked him, with a bigsmile on my face. “Let's just see what we can do for you, little man,”he said. I was so happy when he started to cut my hair. Just as he started to cut my hair, the matron signed for him to come over to where she was standing. She whispered something into his ear and then he shook his head, like he wastelling her“No”. Then he toldme they were not allowed to give us Elvis hair cuts. Then I saw my hair falling onto the floor

    In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame (驯化的) fox population. Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk, in Russia, he sought to find the evolutionary pathway of tame animals. His test subjects were silver-black foxes, a melanistic (带黑色的) version of the red fox that had been bred in farms for the color of their fur.

    He selected the animals based on how they responded when their cage was opened. About 10% of the foxes displayed a weak “wild-response”, meaning they were docile around humans. Those that hid in the corner or made aggressive voices were left in the farm. Of those friendly foxes, 100 females and 30 males were chosen as the first generations of parents.

    When the young foxes were born, the researchers hand-fed them. They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. If the young foxes continued to show aggressive response, even after significant human contact, they were thrown away from the population—meaning they were made into fur coats. In each selection, less than 10% of tame individuals were used as parents of the next generation.

    By the fourth generation, the scientists started to see dramatic changes. The young foxes were beginning to behave more like dogs. They wagged their tails and “eagerly” sought contact with humans. By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could “read” human hints and respond correctly to gestures or glances.

    Since 1984,Philadelphia has been cleaning up its act.One by one,graffiti（涂鸦）covered walls are being changed into outdoor art.So far,more than 1,800 murals（壁画）have been painted.Philadelphia now has more murals than any other American city.

    The walls that were once ugly with graffiti are now covered with beautiful pictures of historical heroes and modern art, thanks to the Mural Arts Program(MAP).Its work makes schools and public places attractive,and its citizens very proud.The program began as part of Philadelphia's Anti-Graffiti Network.Jane Golden is the MAP's artistic director."When people ask me what our program is about,"she says,"I answer them with one word: hope." Each year, the MAP offers youth art programs and workshops.Some onetime graffiti writers even help paint MAP murals.

    The MAP's work,says Golden,is all about developing a sense of community（社区）.When a neighborhood requests a mural,the MAP works with the people there to develop a message.Some messages have been "Safe Streets,"Love and Care," and "Peace Walk".

    The MAP receives up to 50 requests for murals each week. Last year, the workers painted 140 murals."The making of a mural enters people's collective memory as an extraordinary, pleasant moment in neighborhood history," says Golden, who began as a muralist in Los Angeles.

    Reducing plastic waste isn't easy because the cheap material is found in almost every household item. Now, a delicious and nutritious solution has come up to help reduce our dependence on this environmental hazard.

    David Christian, the co-founder of Evoware, says the idea of creating the biodegradable (生物降解的) products came from concern at the country's high pollution rate. Indonesia is home to four of the world's worst polluted rivers. Since single-use packaging is a large contributor to the problem, Evoware decided to deal with that first.

    After investigating various materials, the company settled on seaweed. Unlike corn, commonly used for biodegradable containers, seaweed does not require resources like water or large amounts of space. Since Indonesian farmers already harvest more seaweed than they can sell, it's easy for the company to find the material.

    Though they will not reveal their production process, Evoware says the seaweed packaging contains no chemicals and is safe to consume. The company has also invented single-use cups, which can break down 30 days after they're thrown away.

    While replacing plastic with the seaweed products may seem appealing to most of us, it is a hard-sell in Indonesia. According to Christian, “The awareness to reduce single-use plastic is still very low. This makes our bioplastic unnecessary.” Also a factor is the cost, which is higher than using plastic. Hopefully, Evoware will succeed in convincing Indonesians and people worldwide that switching to their products will be helpful to protecting our beautiful planet.

    It's Friday night. You're looking through your Instagram (a photo-sharing app) feed when you see it: a photo of your friends hanging out without you.

    Why didn't anyone invite you? What are they doing later? Should you text them? What if no one responds (回应)?

    Sounds like a typical case of FOMO.

    FOMO, or "fear of missing out", is a form of anxiety that causes people to feel like they're missing out on something. The word was added to The Oxford English Dictionary last year. But just how serious is FOMO?

    According to a study by a US research organization, JWTIntelligence, 47 percent of teen millennials (those who are 13-17 years old now) feel upset or nervous when they learn that their friends are doing something they're not. And 41 percent said they spread themselves too thin, trying to do too many things at one time to avoid FOMO.

    Today's technology is a big cause of FOMO, according to Jonathan Pochyly, an adolescent psychiatrist (青少年精神病学专家) at Lurie Children's Hospital in Chicago.

    "Technology is one of the things that makes life special for adolescents these days," he explained.  

    "There's a lot of focus on what everyone else is doing. It became a trend, so there's pressure to keep up with it."

    As social media (社交媒体) feeds are always updating us with our friends' activities, it's easier than ever to feel left out. So what can we do?

    To fight against FOMO, Jones freshman Emmy Brewer just calls people and talks to them.

    "I'd be upset for a bit, but then I'd realize that I should be reaching out to them," she said.

    Oak Park and River Forest High School senior James Cullinane said he fights off FOMO by living in the now.

    "If I'm hanging out with my friends, or just sitting at home on my couch, I think it's best to stay off social media and focus on what I'm doing in the moment," Cullinane said.

    While FOMO will continue to affect (影响) teenagers in the future, Pochyly said that he believes these feelings are just side effects of growing up.

    "These types of interactions (交往) with people are … a function (功能) of kids being more independent, looking for connections with other people, moving away from just being a child in a home, and moving toward adulthood," he said.

    It's nice to have people of like mind around. Agreeable people boost your confidence and allow you to relax and feel comfortable. Unfortunately, that comfort can hinder the very learning that can expand your company and your career.

    It's nice to have people agree, but you need conflicting perspectives to dig out the truth. If everyone around you has similar views, your work will suffer from confirmation bias (偏颇).

    Take a look at your own network. Do your contacts share your point of view on most subjects? If yes, it's time to shake things up. As a leader, it can be challenging to create an environment in which people will freely disagree and argue, but as the saying goes: From confrontation(冲突) comes brilliance.

    It's not easy for most people to actively seek conflict. Many spend their lives trying to avoid arguments. There's no need to go out and find people you hate, but you need to do some self-assessment to determine where you have become stale(疲沓的) in your thinking. You may need to start by encouraging your current network to help you identify your blind spots.

    Passionate, energetic debate does not require anger and hard feelings to be effective. But it does require moral strength. Once you have worthy opponents, set some ground rules so everyone understands responsibilities and boundaries. The objective of this debating game is not to win but to get to the truth that will allow you to move faster, farther, and better.

    Fierce debating can hurt feelings, particularly when strong personalities are involved. Make sure you check in with your opponents so that they are not carrying the emotion of the battles beyond the battlefield. Break the tension with smiles and humor to reinforce the idea that this is friendly discourse and that all are working toward a common goal.

    Reward all those involved in the debate sufficiently when the goals are reached. Let your sparring partners (拳击陪练) know how much you appreciate their contribution. The more they feel appreciated, the more they'll be willing to get into the ring next time.
