Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I would draw your attention to a few of our laws.

    The first one is drinking. Now, you may not buy wine in this country if you are under 18 years of age, nor may your friends buy it for you.

    Secondly, noise. Enjoy yourselves by all means, but please don't make unnecessary noise, particularly, at night. We ask you to respect other people who may wish to be quiet.

    Thirdly, crossing the road. Be careful, the traffic moves on the left side of the road in this country. Use pedestrian crossing(人行横道) and don't take any chance when crossing the road.

    My next point is about rubbish. It isn't lawful to drop rubbish in the street. When you have something to throw away, please put it in your pocket and take it home, or put it in a dustbin.

    Finally, as regards smoking, it is against law to buy cigarettes or tobacco if you are under 16 years of age.

    I'd like to finish by saying that if you require any sort of help or assistance, you should contact the police, who will be pleased to help you. You can call, write or directly go to any policeman.

    When her five daughters were young, Helen An always told them that there was strength in unity (团结). To show this, she held up one chopstick, representing one person. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.

    Helen An and her family own a large restaurant business in California. However, when Helen and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helen and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helen did not want her daughters to always work in the family business because she thought it was too hard.

    Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elizabeth explains, “Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business.”

    Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $ 20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.

    Thousands of taxi drivers in Shenyang, Liaoning province, reportedly blocked streets with their vehicles on Sunday in protest against unlicensed vehicles using taxi-hiring apps and apps-based car rental companies providing passenger services, including high-end cars. Although the drivers also complained about the withdrawal of the fuel subsidy (补贴)by the government, their main complaint was the loss of business because of the rising number of Internet-based car services companies.

    On Wednesday, news reports came that Beijing transport authorities will take measures to stop the illegal “taxi business” of private cars through the newly rising Internet apps, following the footsteps of Shenyang and Nanjing.

    It is not yet clear how the Shenyang city government will handle the issue and whether it will declare the services offered by market leaders such as Didi Dache, a taxi-hiring app provider backed by Tencent Holdings, and Kuaidi Dache illegal. But Shanghai transport regulators (交通管理结构)have set a rule, by banning Didi Zhuanche, or car services offered by Didi Dache in December.

    Such regulations will cause a setback to the car-hiring companies and investors that are waiting to cash in on the potentially booming business. Just last month, Didi Dache got $700 million in funding from global investors, including Singapore state investment company Temasek Holdings, Russian investment company DST Global and Tencent. Besides, the market is uncertain that Kuaidi Dache is about to finalize its latest round of funding after getting $800 million from global investors.

    Regulatory uncertainties, however, could cast a shadow on the future of the Internet-based car-hiring services, which have become popular in most of China's big cities. To be fair, these companies' business model is anything but bad. For example, Didi Zhuanche works side by side with established car rental companies to provide high-end car service mainly for businesspeople through the Internet and mobile phone apps.

    Every link in this business model chain has legal companies and services. Hence, it is hard to define it as illegal and ban it.

Don't Drop the Ball

    Drop prevention risk assessment is really important. Everyone knows objects get dropped on work sites – there's nothing radical about that. In Australia, mining has the third highest fatality rate of any industry (4.4 fatalities per 100,000 workers in 2015), and in less well-documented areas like India the fatality rate is even higher. A lot of these fatalities come from dropped objects. It's worth trying to address this and work out just how big the risk is and where it comes from. At the end of the day, safety should be a priority in any industry and it should come as no surprise that addressing safety issues early can actually save money, long-term, for companies. It doesn't look good for a mining company if people are getting injured and equipment damaged from falling objects.

    The risks from dropped objects come from all sorts of areas; it's not just a matter of dropped tools. We're talking about sites characterized by a lot of activities, where all sorts of things can come loose or fall, whether its light fittings or objects like rocks falling off transporting belts. The risks are largely personal but are also financial: if a piece of equipment gets damaged it will need replacing. That's a pretty strong inspiration for companies to address these risks. In terms of frequency, here in Australia we're looking at around 18% of compensation claims coming from workers being hit by moving objects, but those are just the claims – the frequency is likely higher. Around 28% of deaths and injuries come from such incidents, too. As I said earlier, that's just Australia; some industries don't keep statistics, but I wouldn't be surprised to find other countries report comparable rates. That's a lot of accidents that could be prevented with adequate safety measures.

    It's important to take an active approach. It's a lot easier and cheaper to address these risks during the installation or maintenance phases by adding barriers to the inside of guard railings on walkways and transporting systems and adding nets to fixed devices. There are safety mechanisms available, but it's up to the companies to install them. It is a lot more efficient to add barriers right from the start rather than waiting for an accident and then thinking, "Should we be safer?", when they should have reduced these risks from the start.

    The first day my new teacher walked into our school in Spanish Harlem, I burst out laughing. Ron Clark was this young white guy from North Carolina who talked with a funny Southern accent(口音). He said he used to be a singing waiter. I thought, who is this guy? He's a complete joke.

    It was 1999 and I was in the fifth grade at New York City's P.S. 83. I guessed I'd spend most of the year in the headmaster's office. I'd always been a troublemaker. I'd get shouted at, and then the teachers would give up on me. I thought that's what would happen with Ron Clark.

    I was wrong. That first week, I kept laughing at him. He pulled me out to the hallway and said I'd better shape up(表现好). "Tamara," he said, "you're a smart kid. You can do better."

    He told me I was a natural leader and that I'd go far in life if I started studying hard. I was mad at first, but then something happened: I began to respect him. There were 29 students in our class, and it didn't take long for us to realize that Ron Clark was no ordinary teacher.

    Like most teachers, he had lots of rules: Treat each other like family. Don't cut in line. But the real difference was how concerned he was. Mr. Clark ate with us in the lunchroom instead of going to the teachers' day-room. At first, my friends and I were thinking. What is he doing?

    He asked us what was going on in our lives. Between classes, he came outside with us, and we taught him how to jump rope. When it snowed, Mr. Clark, who'd never seen snow before, threw us with snowballs, and we threw him back.

    Before coming to P.S. 83, he taught at Snowden Elementary in his hometown, Belhaven, North Carolina. His parents were DJs(流行音乐节目主持人)at dance clubs, so he grew up with music and energy. He wanted a life of adventure, he told me, but his mom encouraged him to ask for a position at Snowden when one of the teachers passed away. Mr. Clark ended up loving it. He came to Harlem because he'd seen a TV show about our troubled schools and the lack of qualified teachers. He wanted a challenge. Boy, did he get one.
