The mobile phone has become a problem for high schools. Some high-school students in Australia are not allowed to carry mobile phones during school hours.

    The mobile phone used among children has become a problem for the school years. Several children have got mobile phones as Christmas presents, and more students want them. Marry Brown, a headmaster, said that the mobile phone was a distraction to students during school hours and it also gave teachers so much trouble in their classrooms. Teachers also say that sometimes students might use phone messages to cheat during exams.

    She said some schools had tried to ban mobile phones.  Some parents felt unhappy because they couldn't get in touch with their children.

    Many teachers said students should not have mobile phones at school, if there was a good reason, they could leave their phones at school office. They also said phones were easily lost and were a distraction for studies.

    Many people say that they understand why parents would want their children to have phones, but they think schools should let students know when they can use their mobile phones.

    “There's a mother in PICU (儿童重症监护病房) who wants to talk about a kit she received.” the nurse told me. “Something about it made her cry.”

    I've been a child-life specialist at the Cleveland Clinic Children's Hospital since 2000. I help families understand diagnoses and treatment plans and manage the ups and downs that come with caring for a sick child. Tough talks with parents are part of the job, it still makes me feel nervous.

    The kits the nurse was talking about were something I had recently introduced to the hospital: Comfort Kits from Guideposts. They were supposed to make a child's experience here easier, not upsetting.

    When I came across the kits at a conference, I fell in love with them. A treasure box of items designed not only to entertain kids, but to comfort and inspire them. There's a coloring book, a stress ball, a CD of relaxing music, a hairy star named Sparkle, a journal and much more. I really believed these kits would help kids. I wished I hadn't been mistaken.

    At the patient's room in PICU I saw a little girl, sleeping soundly, surrounded by tubes and machines. My eyes met her mother's. The kit was open on her lap and tears were running down her cheeks.

    “I'm Shannon. I manage the Child Life Department.” I said. “I'm sorry if the kit upset you. It's a new item…”

    The mother shook her head. “This has been one of the worst days of my life. I felt so scared and alone. Then I was handed this box. I know it's for my daughter, but it's just the comfort I needed. I wanted to say thank you.”

    With that I knew Comfort Kits belonged here. We've been using them for almost three years now. Each child who's admitted to the hospital receives one. Every day I see kids coloring, journaling, playing with Sparkle.

    But as this mom showed me Comfort Kits aren't just for kids. The hope they bring, which can be in short supply in hospitals sometimes, is felt by the whole family.

    Why Black Friday Shoppers Still Crowd Stores

    To many of us, the ideas of rushing out to a superstore the day after Thanksgiving is appealing. Why would anyone race to crowded stores when they could stay in with family, or watch college football? We can't say we know the answer for sure. But we do feel amazed at those who pour into stores looking for Black Friday bargains. Seemingly, nothing can stop them. Not the weather. Not the crowds. And not the fact that hurrying to a store in the age of instant e-commerce seems so…last century.

    To be sure, holiday shopping habits do appear to be shifting. The National Retail (零售) Federation has stopped breaking up its holiday sales numbers by whether they come from e-tail purchases or from physical stores. It's a pretty good sign that retailers don't want to bring further attention to the declining fortunes of brick-and-mortar stores.

    But there is no denying that people still love going to stores. Actual shopping in actual places remains an important part of the holiday ceremony for millions of Americans. To many, it's the difference between playing a sport and playing a video game. As commercial as stores may be, they are still places where actual human beings interact. In a store, the “courageous” shopper performs the approving act of finding a present. That item might be heavily promoted by the store, but it doesn't drop into one's cart. It is picked up and examined before a decision is made. Maybe it gets put back on the shelf when the shopper changes his or her mind. Maybe there is a conversation with a sales clerk. The process is not that different than it would have been decades ago.

    Online, the shopper has barely logged in before being faced with disturbing algorithmic (大数据的) suggestions based on earlier purchases. This hardly qualifies as shopping. This hardly qualifies as thinking.

    Perhaps we are reading too much into the Black Friday phenomenon. But we suspect one reason Black Friday remains is that it involves an act of resistance against the Internet age. That would hardly be unreasonable. There aren't many studies showing that time spent in stores is bad for one's health, while there are quite a few drawing a link between time spent online and depression. Perhaps the people crowding into stores aren't the crazy ones after all.

    When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.

    So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.

    Whatever it takes for us to reduce pressure is important to our emotional health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.

    Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendlier and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.

    Just as crying can be healthy, not crying - holding back tears of anger, pain or suffering - can be bad for physical health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural –and healthy-emotional response.

    A university in Nanjing, Jiangsu province, has installed facial recognition systems in classrooms to monitor students' behavior, sparking a heated debate online. China Pharmaceutical University recently installed the systems in two pilot classrooms as well as school gates, dormitory entrances, the library and laboratory buildings.

    Xu Jianzhen, director of the university's library and information center, told TbePaper.cn that the systems will help teachers check student attendance and monitor behavior during the lectures. "In the past, some students just checked their attendance and ditched the class or asked other students to check the attendance for them. Now with facial recognition, that would no longer be a problem," he said. "The moment you enter the classroom, the camera will monitor you all the way through and can tell how long you lower your head, whether you're playing with a smart phone, whether you're dozing off or reading other books," he added.

    The news has raised wide debate on Chinese social media, with many questioning if the cameras will violate students' privacy. A Sina Weibo user said: "I oppose such methods, and it is not clear whether the systems are developed by the school itself or by third parties. If it is the latter, is there any regulation of security? Where will the information be sent and stored?"

    Gan Xiangsi, a senior student from the university, said she welcomed the systems being applied in dormitories and libraries as this can help prevent personal belongings being stolen，but it is not necessary to use such technology in the classroom. "If the teacher teaches well，the students will be interested," she said. "On the contrary, this kind of monitoring will make everyone feel resistant."

    China Pharmaceutical University is not the first university to use facial recognition technology on campus. Many universities across the country have installed cameras at campus entrances to ensure safety. But many are also hesitant when it comes to applying such technology in classrooms.

    "This issue has been debated for quite a long time," Chu Zhaohui, a senior researcher at the National Institute of Education Sciences, told China National Radio. According to Chu, teachers and students who are under observation might not behave as they normally would since they know they are being watched. "Cameras should not be installed in classrooms merely for effective teaching purposes," Chu said, as teachers are also being observed. He agreed that "students' privacy needs to be protected". He also said that not putting classrooms under control is an important principle. "If you don't follow this principle, students will falsify and disguise their state of listening，and teachers may also not perform as well. Then real teaching will not occur," he added.

While conquering the world's swimming pools in the late 1990s and the 2000s, Amanda Beard had already included breathing exercises in her training. Several years after the end of her athletic career, she discovered walking meditation. Today the seven-time US Olympic medalist practices walking meditation in nature, around the house, or while walking the dog. It's a daily practice with the focused mindfulness of meditation that contributes positively to every aspect of her life, she says. 

You don't need equipment or a designated space to start. The idea of a walking meditation is to pay attention to the way your body feels, noticing things like the sky, trees, tuning into all of your senses. This means you can meditate "on the go" in the countryside, in the city, in your backyard, and virtually anywhere. A simple, 10-minute walking meditation for beginners requires that you just start at ease. Consider what you hear, smell and see. Think about how your feet touch the ground. Fully focus on these feelings. 

A report in Health Promotion Perspectives also found that walking meditation can improve your balance, adjust your heart rate, boost your mental focus, and help you battle anxiety and depression. "The benefits of meditation are many," says Dr. Schramm, a board-certified family physician and meditation teacher. "When we do this over and over again, we train the brain to focus on only one thing at a time and this increases both our blood flow and actual neuronal (神经元) changes within our brains. "

"The magic of meditation is to be able to help you connect with yourself; meditation shouldn't feel a certain way," says Tara Stiles, a yoga and wellness expert. It's a common mistake in meditation: People fear a wandering mind. "A wandering mind is completely normal," Stiles says. "Even experienced meditators aren't sitting there never having a thought, but when they have the thought they choose to guide themselves back to their breath instead of getting frustrated.
