    Global GDP in 2030 will be 14% higher as a result of AI (Artificial Intelligence), thanks to improving labor productivity and increasing consumer demand, says a report.

    The report could increase the enthusiasm of economic policymakers and the public, and show the power of technology in changing not only people's daily lives, but also economic activities. However, history tells us that, while technological advancements have brought us benefits, they have also led to great social disorders, by changing the production and labor structures, and forcing many workers to either adapt to the changes or lose their jobs. In the 18th century, for instance, skilled workers rose up to resist the Industrial Revolution, destroying machinery in the early 19th century. We may not see similar protests today, but history should serve as a warning against the application of AI technology.

    While we may gain a lot of benefits from AI, we must work out plans to reduce its negative effect on society, especially for workers. AI can raise productivity and expand GDP, but it can also make non-adaptive workers jobless. In India, some technology personnel have already felt the negative effect of information technology. As technology industries across the world seek increasing support from automation（自动操作）, robotics and big data analysis, some technology workers have already lost their jobs.

    In their 2013 research study, Michael Osborne and Carl Frey from Oxford University estimated 47% of the jobs in the United States are “at risk” of being automated in the next 20 years. They said jobs in transportation and office and administrative support are at high risk of being automated. And Kaifu Lee recently said that robots could take away about 50% of all jobs from humans in the next decade.

    Those estimates may sound sensational and the impact of technological advancements may not be that serious, as they will also create jobs in new industries. However, policymakers should consider how to better embrace the technological wave to bring benefits while taking action to minimize its negative effects. The government therefore needs to work together with business leaders and social organizations, to promote training programs for potentially helpless workers, in order to make them more capable of adapting to the structural changes in industries and job markets in the future.

    Amy Pankratz spent a few nights in the hospital with her daughter, Isabella, who caught a bad flu. “Lying in bed beside Isabella, I could hear the cries of children in pain, ”says Amy. “It completely broke my heart. ”

    When Isabella was getting well and could leave her room, she wore her prized possession—a “superhero cape(短斗篷)”Amy had sewn to encourage her—and walked into the hallway. The pink cape was an instant hit with the other young patients, who were doing exercise around the nursing station. “Then, all the kids were taking turns wearing the cape, giggling, ”Amy says. “These were some of the same children I had heard crying the night before, and here they were playing and having fun—kids just being kids! ”

    From that moment on, Amy began making Comfort Capes for little ones battling with serious illnesses. “I felt God presenting an opportunity, ”she says. “I hoped Comfort Capes can help these kids feel brave, to lift some of the fear away. ”

    Since then, Amy has made and donated more than 5, 000 capes in the United States. Amy usually pays for materials herself, although she accepts donations.

    The capes she makes for kids in treatment are different from those her own children have. Before Amy starts to sew she learns what image or character the little boy or girl connects with. “ I choose the pattern, color and theme specially for each child,” explains Amy.

    When she is not sewing, Amy is raising awareness of childhood cancers and looking into ways to get Comfort Capes to more kids who need them, “ If a cape can help a child, even only for a moment, forget his illness, it's worth the time spent sewing,” she says.

    I am Henry Jekyll. I was born in the 1 800s. I inherited(继承) a large fortune, a healthy body and an excellent mind. I was naturally hard-working and soon I was very successful in my job. So the outside world saw a serious, hard-working, successful doctor. Behind this quiet character, however, was a wild, fun-loving, irresponsible young man. Both of them were me. They lived together in the same body.

    “Was it possible," I wondered, “to find a drug that could give each side of my character its own separate face and body?"

    After much thought and careful study I believed I had found the answer. I had read many scientific books and spent many hours in my laboratory, searching for the right mixture of chemicals to make my drug. At last I got everything ready.

    Late one night, I mixed everything together and prepared my drug. I watched the smoke rising from the liquid as its color changed from red to purple and at last to green. Then, bravely, I drank every bitter drop.

    I felt a violent sickness in my stomach and a terrible pain in all my bones. The room seemed to turn round and round and I trembled with fear. Then the fear and pain disappeared and a strange, sweet feeling took its place. Wild thoughts danced through my mind- the wild passions of an evil and cruel stranger. But inside myself I felt younger, lighter, more carefree than ever before. "If this is pure evil," I thought, “I like it.”

    I stood there, enjoying these strange new thoughts and passions and suddenly realized that I was shorter. So I decided to go to my bedroom in my new body and take a look at myself in the mirror there. As I came into my room, I saw Edward Hyde for the first time.

    At that time, the good side of my character was stronger than the evil side. Henry Jekyll had his faults, but he was mostly a good, kind man. I believe that is the reason why Edward Hyde was so much smaller than Henry Jekyll. But that was not the only difference between the two men. Henry Jekyll had a kind, open, honest face. But pure evil stared out of Edward Hyde's eyes. I felt no dislike, however. Indeed, I welcomed him. Edward Hyde was me, young and strong and full of life.

    New Jersey Middle School Makes Students Go Phone-Free

    A middle school in Union County, New Jersey, is forcing its students to stay disconnected in class, by prohibiting cellphones. Maxson Middle School Principal Kevin Stansbury put forward the phone ban last week after he noticed some major issues in the school. "Our test scores were down, discipline was up," he says. According to him, students were too focused on their phones to pay attention to their lessons. So, he purchased Yondr pouches for the school.

    Yondr pouch

    When students come into class each morning, they place their phones in the pouch, which is then locked up tight. It can only be opened using a special device at the end of the day. The ban on mobile devices applies not just during class time but during breaks, with the only exceptions being in times of emergency or in cases of students who need such devices to help with disabilities.

    Eighth-graders who spoke with News 12 New Jersey say that they noticed a change in a matter of hours. "It's just better for everyone because you'll understand how it feels to get more work done instead of paying attention to the phone," says student Charlene V. "I'm usually listening to music, but today I got to communicate with all my friends," says student Desiree Duncan.

    The program was originally met with resistance from students and parents, so the process was not that smooth. But teachers and administrators say that the program will have a major impact. "Students were talking and laughing and there were no cellphones other than being carried in the pouches," Stansbury says.

    Teacher Nia Cummings says she even noticed students bouncing ideas off each other in class. She says students used to give up quickly and just look for answers on their phones. She says they now try to figure it out themselves. "Everyone is socializing and eating lunch together. That's what I wasn't seeing enough of when phone usage was at its worst," she adds.

    Maxson Middle School is currently the only one in the district to use these pouches. Kevin Stansbury also called on all the schools in the community that it's worth paying close attention to cellphone issues at secondary schools and taking actions when necessary.
