Twelve years ago, I was a 19 -year-old guy living in the French A1ps. In February 2004, while skiing the back - country in Val d'Isere, I fell off the mountain, resulting in a right leg broken in several pieces. I was helicoptered to hospital, operated on immediately—and there started my adult life.

    Before the accident, I was on a path to what I hoped would be a career in rugby. After-wards, and participation in collision sport was gone. I found a replacement in cycling. Unfortunately, by late 2012, I tried to cycle up Mount Ventoux, but it was halfway up when the pain hit me and I gave up.

    A decision needed to be made on a next step. I had to have my lower right leg cut off. Several months later, I had my first proper weight - bearing prosthetic (假肢). I jumped on a train with my bike to Mount Ventoux. Though it certainly wasn't my quickest, I did it.

    Two weeks later, I was lucky enough to be given a running blade; I bounced on it that day and then raced my triathlon (三项全能) on the Monday. So, that was me, up and running - almost 12 years since I had last run.

    Along with my running coach, I complete a “make every kilometre count” programme of four runs per week alongside a busy cycle, swim and gym schedule. So far this year, I have raced a 10k with an unexpected personal best in January of 38:04. I have my first speed triathlon in late March before heading to North Korea to compete in the Pyongyang Marathon on 10 April.

    If my lifetime allows, I will attempt to race in every country in the world. In the meantime, I'll keep on running — and, when it hurts and I'm low on motivation, I'll remember how far I've come and how much further I've got to go.

    Having good etiquette(礼节，礼仪) at the workplace is very important to be a favorite in an office. However, many people aren't aware of the workplace etiquette and this creates a very bad impression in the office. So it's important to know some workplace etiquette tips.

    Among all the workplace etiquette guidelines, the most important is to be punctual(准时的) to your office. Though going late due to an emergency is okay, habitual late comers are never appreciated in any organization. By arriving at your office on time, you show that you're aware of your responsibilities and have respect for the organization. In case you feel that you would be late, call the concerned authority and report the matter to him or her.

    Also, a proper knowledge of the workplace email etiquette is a must. In the official emails, you need to mention the subject concisely (简洁地), while at the same time include all the important details which are to be shared. You should use good and grammatically correct language while writing emails.

    A knowledge of telephone etiquette in the workplace is very important as well. While talking on the telephone, be polite and listen to what they're saying carefully. Only then should you say what you feel. Speak in a voice which would be heard clearly at the other end.

    The workplace guidelines are important even while you're dining or celebrating with your co-workers. If you get a call in between, receive it after you're permitted by the others by saying "excuse me". Don't talk loudly while eating. Greet people well and try to make them feel comfortable, while being in your company.

    These guidelines will help you become the best employee of a company. All the best!

    It's not unusual to see an unreasonable child lying on the ground drumming his heels. Beside him is a desperate mother yelling at the top of her lungs. Raising a well-behaved kid is really a head-scratching thing.

    If you took all the parenting styles around the world and ranked them by their gentleness, the Inuit (因纽特人) approach would certainly rank near the top. All the moms mention one golden role: Don't shout or yell at small children. Inuit's no-yelling policy is their central component to raising cool-headed kids. The culture views scolding, or even speaking to children in all angry voice, as inappropriate, although little kids are pushing parents' buttons.

    Playful "storytelling" is another trick to sculpting kids' behavior. But this storytelling differs hugely from those fairy tales full of moral lessons. Parents "retell" what happened when a boy threw a tantrum(发脾气)by way of what Shakespeare would understand all too well: putting on a "drama". After the child has calmed down, the parents will review what happened when the child misbehaved, usually starting with a question: "Can you show us how to throw a tantrum?" Then the child has to think what he should do. If he takes the bait and performs the action, the mom will ask a follow-up question with a playful tone. For example: "Does that seem right?" or "Are you a baby?" She is getting across the idea that "big boys" won't throw a tantrum.

    Kids' brains are still developing the circuitry needed for self-control. What you do in response to your children's emotions shapes their brains. So next time, seeing your boy misbehave, try using the Inuit's storytelling approach. And don't forget to keep cool. After all, boys will be boys.

    About one million adults in the USA need someone to help them eat. Researchers at the University of Washington are working on a robotic system that can help make it easier. After identifying different food on a plate, the robot can decide how to use a fork to pick up and deliver the desired bite to a person s mouth.

    "Being dependent on a caregiver to feed every bite every day takes away a person's sense of independence," said the researcher. "Our goal with this project is to give people a bit more control over their lives the idea was to develop a feeding system that would be attached to wheelchairs and feed people whatever they wanted to eat.

    "When we started the project, we realized there are so many ways that people can eat a piece of food depending on its size, shape or consistency(坚实度)," said the researcher, "So we set up an experiment to see how humans eat common foods. "

    The researchers arranged plates with about a dozen different kinds of food, ranging in consistency from hard carrots to soft bananas. Then the team gave volunteers a fork and asked them to pick up different pieces of food and feed them to a model. The fork contained a sensor to measure how much force people used when they picked up food.

    To design a feeding strategy that changes based on the food item, the researchers combined two different algorithms (算法). First they used an object-detection algorithm called Retina Net, which scans the plate, identifies the types of food on it and places a frame around each item. Then they developed SPNet, an algorithm that examines the type of food in a specific frame and tells the robot the best way to pick up the food.

    The team is currently working with the Taskar Center for Accessible Technology to get advice from caregivers and patients on how to improve the system to meet people's need.

    A university in southwest China's Chongqing City set up a reading room as part of a campaign(活动)that stops students from taking their mobile phones with them in case the device distracts(使分心)them from focusing on their studies.

    Reportedly a student named Hu Xiaopeng taking part in the campaign studied 530 minutes without using his mobile phone. Unlike Hu, another one picked up his mobile phone in less than 20 minutes. "Having seen many students use their mobile phones in the library, a habit that shortens their study time and negatively affects their learning, we decided to open this reading room," said Zhang Shuran, the person responsible for the project at the university.

    Zhang added that students can keep their phones in appointed bags with numbers on them. The bags are placed on a desk near the door of the reading room. "Staff members at the reading room will check the phones when there's a call," said Zhang, adding that they will inform students when their parents or teachers call them, but will not tell students if an unknown person is calling or when there is a text message. Based on the time students hand in their phones when they come to the reading room and the time they get them back when they leave the room, Hu Xiaopeng from College of Animal Science and Technology of the university set a record of the longest time. Hu spent 530 minutes studying without using his phone. Though feeling somewhat surprised, Hu said, "It's bad to keep mobile phone with you when you are reading or studying."

    The campaign has attracted nearly 200 students since it was started a week ago. Some Internet users praised the campaign. One user named Liu Jingchang said, "It's good. I don't bring my phone when going to the library in case I get distracted."

A recent study has found that using wood for construction instead of concrete (混凝土) and steel can reduce emissions (排放). But Tim Searchinger at Princeton University says many of these studies are based on the false foundation that harvesting wood is carbon neutral (碳中和). "Only a small percentage of the wood gets into a timber (木料) product, and a part of that gets into a timber product that can replace concrete and steel in a building," he says. Efficiencies vary in different countries, but large amounts of a harvested tree are left to be divided into parts, used in short-lived products like paper or burned for energy, all of which generate emissions.

In a report for the World Resources Institute, Searchinger and his colleagues have modelled (塑造) how using more wood for construction would affect emissions between 2010 and 2050, accounting for the emissions from harvesting the wood. They considered various types of forests and parts of wood going towards construction. They also factored in the emissions savings from replacing concrete and steel.

Under some circumstances, the researchers found significant emissions reductions. But each case required what they considered an unrealistically high portion (份额) of the wood going towards construction, as well as rapid growth only seen in warmer places, like Brazil. In general, they found a large increase in global demand for wood would probably lead to rising emissions for decades. Accounting for emissions in this way, the researchers reported in a related paper that increasing forest harvests between 2010 and 2050 would add emissions equal to roughly 10 percent of total annual emissions.

Ali Amiri at Aalto University in Finland says the report's conclusions about emissions from rising demand are probably correct, but the story is different for wood we already harvest. "Boosting the efficiency of current harvests and using more wood for longer lived purposes than paper would cut emissions," he says. "We cannot just say we should stop using wood."
