Sleep deprivation(缺失)is an important hidden factor in lowering the achievement of school pupils, according to researchers carrying out international education tests.

    It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected.

    In literacy(读写能力) tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group.

    Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta.

    The analysis was part of the huge date-gathering process for global education rankings, the Trends in International Mathematics and Science Study(TIMSS)and Progress in International Reading Literacy Study(PIRLS)

    “I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading. That is exactly what our data show,” says Chad Minnich of the TIMSS and PIRLS International Study Center.

    “It's the same link for children who are lacking basic nutrition,” says Mr Minnich, based at the Lynch School of Education, Boston College. “If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of something more basic. Sleep is a fundamental need for all children. If teachers report such large proportions of children suffering from lack of sleep, it's having a significant impact. But worse than that, teachers are having to adjust their instruction based on those children who are suffering from a lack of sleep. The children who are suffering from a lack of sleep are driving down instruction.”

    That means that even the children who are getting enough sleep are still suffering from this sleep-related lowering.

Profi Cheese Slicer

    Uses a thin wire to slice up to medium-hard cheeses in four inch sections.

    I may own every cheese slicer ever made.I prefer a wire type cheese cutter so I can cut slices that work well on a piece of bread and sandwich.

    This cheese slicer is great for both tasks.It even has adjustable tension on the two cutting wires.A point of information: I did break a wire cutting a very hard piece of cheese with black pepper.Good news,the wire is replaceable,and I was able to purchase new wires to fix it.Maybe best to use on softer cheeses.Lessons learned.But, highly recommended for every other use except for those extremely hard cheeses.

Ash Bucket(桶子）

Bucket with lid keeps your fireplace(壁炉）clear of ashes.

    I purchased this ash bucket recommended by my friend and have found it invaluable.Previously I had an old bucket that got left outside and usually filled up with rain and became a mess to clean.This ash bucket has a raised bottom and thermal insulation(隔热层）to prevent any accidental hot coals in your ash to damage your floor or cause a fire.You can store this bucket indoors since the lid is nice and tight.

    I recently posted a picture on Facebook from the movie Mad Max, a film where two groups race through the desert in steampunk vehicles, and wrote, “Actual picture of my way to work today.” It was meant to be a joke because of the sandstorms in Beijing, but one of my friends from back home thought it was real.

    I couldn't imagine how they could think that is actually what China is like. China has so many more conveniences and advantages than the West, and many of my friends agree. “I don't know how I will be able to deal when I go back home,” said a friend who is about to end her gap year in Beijing. “I've become so spoiled in China.”

    China seems to be leading the way in innovation(创新) and convenience for daily life. Back home I could never shop, pull out my phone and scan a QR code to pay.

    There have been rumors of starting bike sharing in my hometown for years with little success while bike sharing suddenly appeared in Beijing overnight. I just step outside and scan a code, and I am on my way.

    Going out to eat with a group of friends back home was troublesome for both the group and the servers. Splitting bills and swiping(刷) 10 different cards or making change for each person in the group can be a pain. But with China's WeChat, you can quickly send your friends your part of the bill.

    The list goes on…

    When I first arrived in Beijing, I was dead set on leaving in a month. That month has come and gone. Now, when someone asks me when I'm coming back, I think to myself, “Who knows?”

    While my friends think I am riding through the desert on a motorbike, I am actually taking a Didi for what is the equivalent of $5 in the US.

    With all the conveniences and technology here, I may never want to go back.

    Skateboarding is an action sport which includes riding and performing tricks using a skateboard, as well as an activity for fun, an art form, an entertainment industry job, and a method of transportation. In 2016, it was announced that skateboarding will be represented at the 2020 Summer Olympics in Tokyo, Japan.

    There are various theories about the origins of Skateboarding, but it is generally held that the sport began in the 1940s on the west coast of the USA when metal wheels were attached to a narrow wooden board. In the 1950s, plastic replaced metal as the material of choice for the wheels, and the first "Roller Surfboard" become commercially available, which in turn developed into the skateboard that we know today. The sport was a big hit with the younger generation and grew in global popularity in the 1980s and 1990s. Since the late 1990s, skateboarding has become an important part of street culture.

    However, skateboarding has raised heated discussions in areas where the activity, although legal (合法的), has damaged stone works, steps, benches, and parks. Certain cities oppose the building of skate parks in their neighborhoods, for fear of increased crime (犯罪) and drugs in the area. The disagreement between the old image of skateboarding and a newer one is quite obvious: magazines such as Thrasher describe skateboarding as dirty, and still firmly tied to punk (朋克), while other publications, Transworld Skateboarding as an example, paint a more different and controlled picture of skateboarding. As more professional skaters use hip hop, or hard rock music in their videos, many urban youths, hip-hop fans and hard rock fans are also drawn to skateboarding, weakening the sport's punk image. Besides, group spirit influences the members of this community. In presentations of skateboarding, the evidence of crime is absent, and no attempt is made to tie extreme sports to any kind of illegal activity.

    The good news is that efforts have been made to improve recognition of the cultural heritage as well as positive effects of skateboarding in cities. By raising £790,000, the Long Live Southbank initiative managed to stop the destruction of a forty years old spot in London due to urban planning, a rescuing operation whose effect extends beyond skateboarding. The presence of skateboarders on this public space keeps the area under nearly constant watch and drives homeless people away, increasing the feeling of safety in the area. The activity attracts artists such as photographers and film makers, as well as a significant number of tourists, which in turn drives economic activity in the neighborhood.

He coached for the West Sydney Razorbacks from 2004 to 2006.He was named as a lifetime member in recognition of the efforts he made for the promotion of wheelchair basketball. Discussing the appeal of wheelchair basketball, he commented that,“There is a coating at the edge of the rim(轮辋) that actually lights up like a spark(火花), and it stays for about two to three seconds. That is quite exciting and great fun.”

    April Holmes

    April Holmes lost her left leg below the knee because of a train accident in 2001. Remembering it she said, “I had a life-changing accident in January, 2001. And fortunately I have been able to get back to doing what I love, and that's track and field.” Through hard work, she made records in the 100, 200, and 400 meter events. To live her life to its full potential, she has set up a non-profit(非营利的) organization, the April Holmes Foundation, to help people with learning or physical disabilities while being a role model for them.

    We all carry fear, and accepting the type of fear you carry is the first step in punishing past it. So, here's a breakdown of the fear archetypes(典型) and how to make them work for you. We also invited Dr. Alicia Hodge to give us her feedback in a few of them.

    The procrastinator(拖延症患者)

    The procrastinators often obsess(痴迷于) over the outcome of whatever they're doing and insist on it being perfect. Because of this, they tend to spend too much time planning and researching instead of simply diving in.

    For procrastinators, it's important to push past that fear of starting. Hodge suggests setting a deadline for when your planning and researching period will end and when you'll actually get started.

    The people pleaser

    Those who have the people-pleaser archetype struggle with the fear of being judged and worry most about disappointing others. They have a hard time setting clear boundaries and saying "no."

    "Having boundaries often sounds scary to someone who is used to putting others first" Hodge says. "Remind yourself that you deserve to be prioritized, just as much as other people in your life."

    The self-doubter

    This archetype is dominated by the fear of not being good enough, those who self-doubt tend to feel not confident about their capabilities.

    A good way to overcome self-doubt is to step outside your comfort zone every once in a while – and take note of the outcome. Practice being proactive about your life, you'll be surprised to see just how much you are capable of.
