My friend BJ Gallagher told me a great story recently, about her own experience with resentment (愤恨). She once worked as the training manager for a large newspaper, where she found the corporate culture extremely frustrating. The company was a hundred years old and their past success ha d blinded them to the need for change. Finally, after butting heads with several senior executives (主管) many times, she left the company. But she found that she hadn't left her resentment, frustration, and anger behind when she resigned.

    “I finally decided to write about my experiences and my feelings at the newspaper. I wanted to be rid of that company and those people, once and for all. So I wrote and I wrote. It wasn't just a story that poured out; it was a whole book! We called it A peacock in the Land of Penguins. I was the peacock and those newspaper executives were the penguins.”

    “It took me several more years to finally get over my negative emotions. Through a lot of soul-searching and reflection, I finally was able to let go of my resentment. I came to see that there was nothing personal in the way they treated me, and they were good people doing what they thought best for the company. I was the one who had made it personal. I thought they were making my life miserable on purpose.”

    “Finally, the time came when I decided to make amends (弥补) for the sharp, angry things I had said about the company. I invited my former boss to dinner and made my apology. It was a great healing process for me. I finally felt free of the resentment that had been eating me up.”

    “What was the final outcome?” I asked her.

    “Gratitude,” she replied. “Not only wasn't I resentful any more, I was grateful to the company. If I hadn't had those painful experiences, I would never have written a book. And the book became hugely successful – now published in 21 languages; it transformed my business.”

    You have never seen him,but they're with you every time you fly.They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally.Their ability to withstand（经受得住）almost any disaster makes them seem like something out of a magic book.They're known as the black box.

    When planes fall from the sky,as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30,2009,the black box is the best bet for identifying what went wrong.So when a French submarine（潜水艇）detected the device's homing signal five days later,the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

    In 1958,Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction.That was the first mode for a black box,which became a requirement on all U.S.commercial flights by 1960.Early models often failed to withstand crashes,however,so in 1965 the device（装置）was completely redesigned and moved to the back of the plane-the area least affected bu impact-from its original position in the landing wells（起落架舱). The same year, the Federal Aviation Authority required that the boxes,which were never actually black,be painted orange or yellow to aid visibility.

    Modern airplanes have two black boxes: a voice recorder,which tracks pilots' conversations,and a flight-data recorder,which monitors fuel levels,engine noises and other operating functions that help investigators reconstruct the aircraft's final moments.Placed in an insulated ( 隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel,the boxes can withstand massive force and temperatures up to 2,000℉.When in deep water,they're also able to emit signals from depths of 20,000 ft.Experts believe the boxes from Air France Flight 447,which crashed near Brazil on June 1,2009,are in water nearly that deep,but statistics say they're still likely to turn up.In the approximately 20 deep-sea crashes over the past 30 years,only one plane's black boxes were never recovered.

    It's rare that you see the words “shyness” and “leader” in the same sentence. After all, the common viewpoint is that those outgoing and sociable guys make great public speakers and excellent networkers and that those shy people are not. A survey conducted by USA Today referred to 65 percent of executives who believed shyness to be a barrier to leadership. Interestingly, the same article stresses that roughly 40 percent of leaders actually are quite shy—they're just better at adapting themselves to situational demands. Bill Gates, Warren Buffet and Charles Schwab are just a few “innies”.

    Unlike their outgoing counterparts who are more sensitive to rewards and risk-taking, shy people take a cautious approach to chance. Rather than the flashy chit-chat that defines social gathering, shy people listen attentively to what others say and absorb it before they speak. They're not thinking about what to say while the other person is still talking, but rather listening so they can learn what to say. Along the same lines, shy people share a common love of learning. They are intrinsically (内在地) motivated and therefore seek content regardless of achieving an outside standard.

    Being shy can also bring other benefits. Remember being in school and hearing the same kids contribute, until shy little Johnny, who almost never said a word, cut in? Then what happened? Everyone turned around to look with great respect at little Johnny actually talking. This is how shy people made good use of their power of presence: they “own” the moment by speaking calmly and purposefully, which translate to a positive image.

    Shyness is often related to modesty. Not to say that limelight-seekers aren't modest, but shy people tend to have an accurate sense of their abilities and achievements. As a result, they are able to acknowledge mistakes, imperfections, knowledge gaps and limitations.  Since shy people have a lower sensitivity to outside rewards than outgoing ones, they're more comfortable working with little information and sticking to their inner desires. Shy people are also more likely to insist on finding solutions that aren't primarily apparent. Don't believe me? Maybe you'll believe Albert Einstein, who once said, “It's not that I'm so smart, it's that I stay with problems longer.” Obviously, finding certainty where uncertainty is typically popular is a huge plus for any successful person.

    The myth that shy people are less effective leaders than their outgoing fellows is just a misunderstanding. Make wise use of your personality strengths to lead your business no matter what side of the range you fall on.

    Social media is one of the fastest growing industries in today's world. A study conducted by the US Pew Research Center showed that 92 percent of teenagers go online daily. The wide spread of social media has changed nearly all parts of teenagers' lives.

    Changing relationships

    High school student Elly Cooper from Illinois said social media often reduces face- to-face communication. “It makes in-person relationships harder because of people's attention given to their phones instead of their boyfriends or girlfriends,” Cooper said.

    Yet, some people believe social media has made it easier to start relationships with anyone from anywhere. Beth Kaplan from Illinois met her long-distance friend through social media. He currently lives in Scotland, but they're still able to frequently communicate with each other. “I can feel close to someone that I'm talking to via FaceTime,” Kaplan said.

    Wanting to be “liked”

    The rise of social media has changed the way teenagers see themselves. The 19- year-old Essena O'Neill announced on the social networking service Instagram that she was quitting social media because it made her unable to stop thinking about appearing perfect online. Negative comments also can do great damage to a teenager's self-esteem. Teenagers who get negative comments can't help but feel hurt.

    Opening new doors

    However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube. “Social media can help people show themselves and their talents to the world in a way that has never been possible before,” Korsos said.

    Bob was born in Cambridge. When he was in elementary school, he asked his mother to take him to parks in their community so he could collect empty soda cans to recycle. His mother agreed, as long as he saved part of the money he earned for college.

    Bob's mother remembers Bob as the most determined of her seven kids. Bob's hard work paid off. On Friday, he will become the first person in his family, originally from El Salvador, to graduate from college. And he's graduating with university honors.

    For his honors thesis（毕业论文）he researched unmanned solar-powered（太阳能）airplanes, which BYU students have been building and testing for about 10 years. Bob's study helps discover the best way to fly a solar-powered airplane so that it uses the least amount of power. The goal is to design and build an airplane that flies uncertainly. Bob's thesis helps lay the basis for this work.

    “My parents were always hard-working,” Bob said. “They often tell us hard work leads to success.” Bob's father taught him to read at the age of 3, and his mother is now a student at Utah Valley University in a way to becoming a dentist.

    Bob recognized he overcame some obstacles（障碍）to get where he is. For starters, English is his second language. He also faced stereotypes（模式化的形象）. Although Bob never doubted that he would be a college graduate, other people believed he wouldn't because he didn't come from a family of high income. There were other obstacles as well, but Bob viewed them all as opportunities.

    Bob's mother says she feels very happy and proud that her son is about to graduate with honors, and remembers the effort he's made to get there. “He has worked very hard. He started something, and now he has finished it,” Cathy says. “I have always told him, 'If this is your dream, then you can get it! Keep working hard and you can get it!'”

    Everything about nuclear energy seems terrifically big: the cost, construction and decommissioning—and the fears of something going badly wrong.

    The future, however may well be much smaller. Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk.

    These small-scale plants will on average generate between 50MW and 300MW of power compared with the 1,000MW-plus from a conventional reactor. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger-scale projects. Supporters believe these advanced modular reactors (AMRs)—most of which will not be commercial until the 2030s—are critical if atomic power is to compete against the rapidly falling costs of solar and wind.

    "The physics hasn't changed. It's about much cleverer design that offers much-needed flexibility in terms of operation," said Tim Stone, long-term industry adviser and chairman of Nuclear risk Insurers, which insures nuclear sites in the UK.

    Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley point in Somerset; at Flamanville in France; and at Olkiluoto in Finland. All involve the European Pressurized Reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates.

    The UK, which opened the world's first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power's ability to restore confidence.

    However, the country's agreement with EDF to build two units at Hinkley Point—which together will generate 3.2GW of electricity—has come under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country's future energy mix. Small reactors, it believes, have the potential to generate much-needed power from the 2030s.

    A nuclear sector deal, unveiled last month, promised up to ￡56m in funding for research and development into AMRs and attracted interest of start-ups from around the world. The government hopes the funding will give the UK a lead in the global race to develop these technologies, helping to provide energy security while also creating a multibillion-dollar export market for British engineering companies.
