Neither rain nor snow nor the dark of night can separate Tennessee postal carrier “Mailman Mike” from his 4-and-a-half-year-old friend Carter Lawson – or keep them from their appointments.

    For the past nine months, the two have teamed up every day in the preschooler's Knoxville neighborhood for a few minutes of delivering mail together and chatting with fellow neighbors. Lawson wants to be a mail carrier when he grows up, and in an inspiring story, his mom told us how mailman Mike Crenshaw has been a role model to her son. “Anyone could just be like 'Go away, kid', but Mike has really gone out of his way to talk with Carter,” said Cassie Lawson of the United States Postal Service carrier. Little Carter even got his own uniform to match Mike's. “It's been really cute. I just couldn't believe he got a full mailman's costume,” the postal service employee said.

    “Every letter carrier has stops he looks forward to and this is the one I look forward to every day,” said Mike. “He's the end of my day, and the best part of my day. Not because it's the end, but because he's such a cute little guy.”

    The man and the little boy's connection isn't a surprise to Fredric Rolando, president of the National Association of Letter Carriers. “Kids respond to mailmen because letter carriers are a friendly, uniformed part of the neighborhood who bring something to their house every day, and are someone they come to recognize and trust,” Rolando said. “It's the same for the elderly, but in addition, letter carriers may be the only person they communicate with all day.”

Bell Teacher Campus 2016: Cultural Talks

    Our talks start at 16:00 on the first week in August, and each one lasts about one hour. Each talk will be offered only once during your 4-day stay. Please sign up on the main Bell Noticeboard (Second floor, Mary Allan Building).

August 1st

    BRITISH MUSIC, by Pete Sharma in Room 106. British music is famous worldwide. In this talk, I'll discuss what's popular and what's not right now and the top music festivals in the UK. We will listen to some of the artists and share some thoughts about singing and dancing.

August 2nd

    LOVE ME, LOVE MY CAT, by Lis Harrison in Room 207. We will be looking at this national interest through idioms(习语), songs, and everyday British life, and along the way covering some vocabulary for “talking cat”. At the end, we'll be discussing that old topic: do we Brits treat out pets better than we treat our kids?

August 3rd

    A GAME AS ENGLISH AS CROQUET(槌球游戏)，by Anna Young in Room 218. First, we will look at the origins of croquet, a much loved garden game in England. We will look at simple croquet rules, and then practice time! We'll go out and play!

August 4th

    WHY ENGLISH PEOPLE LAUGH, by Jim Scrivener in Room 117. Let me try to show you a little bit of what British people find funny. You will discover some of the most popular radio& TV comedy game shows. You probably won't find it funny at all! But you will learn a bit more about us Brits!

    If you want to slow aging, you might want to eat less. This finding is good news—if you were a mouse. The researchers studied mice, not people.

    John Price and other researchers studied two groups of mice. One group was able to eat as much as it wanted. The researchers limited what the mice in the other group ate. Their diet had 35 percent fewer calories than the first group of mice.

    Price says the mice with the diet restrictions were “more energetic and suffered fewer diseases.” They were not just living longer but seemed to stay younger for a longer period of time.

    The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down. This gives the cells more time to repair themselves.

    The researchers say ribosomes use from 10 to 20 percent of the cell's energy to make those proteins. Price wrote that “because of this, it is impractical to destroy an entire ribosome” when it starts to break down. However, “repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high quality proteins for longer than they would otherwise. This top quality production, in turn, keeps cells and the entire body functioning well.”

    Price said, “ribosome is a very complex machine, like a car.” They need “maintenance to replace the parts that wear out the fastest. When tires wear out,” he explained, “you don't throw the whole car away and buy a new one. It costs less to replace the old tires.”

    “Food,” he said, “isn't just material to be burned—it's a signal that tells our body and cells how to respond.” Price said the findings help to explain how exactly our bodies age. And this may “help us make more educated decisions about what we eat.”

    Although the idea of "zero emission net carbon-positive, sustainable (可持续)" development was promoted worldwide, most cities are at a loss what to do or even some have objected to it. But in Liuzhou, a city in southern China, attitudes could not be more different.

    The Liuzhou Municipality Urban Planning Bureau has signed up Italian architect Stefano Boeri, the father of the forest city movement, to build a self-contained community for up to 30, 000 people. He is the go-to man for such projects thanks to the success of his "vertical forests", two residential (住宅的) towers. Completed in 2014, they remove up to 17.5 tons of soot (煤烟) from the air each year, and a year later one of them was named Best Tall Building Worldwide.

    The Liuzhou project is a much more ambitious undertaking, however. Its homes, hospitals, hotels, schools and offices will be built on a 340-acre site in what Boeri calls the first attempt to create an "urban environment that is really trying to find a balance with nature". Its 100 species of plant life are expected to absorb almost 10, 000 tons of carbon dioxide and 57 tons of pollutants per year, while at the same time producing 900 tons of life-giving oxygen.

    Although the architects haven't published the cost of the forest city, the Milan towers cost only five percent more than traditional skyscrapers.

    The construction of his forest city at Liuzhou is set to begin in 2020, and there is still a great deal of planning and research required before a projected completion date can be set. However, Boeri remains optimistic about the project and has confidence in the soundness of his vision: "I really think that bringing forests into the city is a way to deal with global warming."

    In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence—as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch (关键时刻), we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instinct remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learned that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed (流血), the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.

    The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised mistrusted and even persuaded by their own kind because they advocate such apparently outrageous things as law enforcement (执行). If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop to the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.

    Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other's problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchange information. "Talk, talk, talk" the advocates of violence say, "all you ever do is talk, and we are none the wiser." It's rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument, the judge complained that after all this talk, he was none the wiser. "Possibly, my lord," the barrister replied, "none the wiser, but surely far better informed." Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.

During a pandemic (流行病), for many reasons, there are lots of poor parents who are isolated (隔离) with their kids, or roommates who are stuck together in an apartment. But what about the people who have nobody to talk to?

It is common that people feel lonely. However, during the pandemic, this situation can be much worse for experiences like long-time hospital stays or being unable to move due to poor health, disability or age.

Recently, a friendly robot named Robin got a test run in the children's treatment center of the Wigmore Clinic in Yerevan. About as tall as an 8-year-old child, Robin's plastic body and square head may not put you in mind of a human partner, but its face screen containing two big eyes and expressive brows (眉毛) is attractive, which can help children forget their stress for a while.

A hospital can be very stressful for anybody. And the time of treatment and recovery might seem tiresomely long to an adult stuck in a hospital bed. For a child who can't play with his or her friends or sometimes even family, the long course and boring atmosphere seem unbearable. That's where Robin comes in. It can recognize (识别) facial expressions and use the mood of a talk to build personalized, natural conversations and dialogues with a lonely child in the way another child might use. Robin also plays games, tells stories, and makes children take part in various other activities.

According to Expper Technologies, the makers of Robin, during the program with Wigmore Clinic, Robin improved the experience of children in the hospital by 26 percent over those who did not have the chance to play with Robin, and reduced their stress levels by 34 percent during their hospital stay. Mary, whose son was one of those users, said, "Thanks to Robin, my son became happy every day during this pandemic." John Smith, a father of a five-year-old girl in the clinic, told a reporter, "Robin is a great partner. It brings big smiles to my daughter's face."
