    According to a new study ,a smiley face emoji（笑脸符）in work-related e-mails may not create a positive impression and could even weaken information sharing. In formal business emails, a smiley is not a smile.

    In one of the experiments, people were asked to read a work-related e-mail from an unknown person and then tell about both the ability and warmth of that person. Before that, they all received similar messages. But some included smileys while others did not. The results suggested that contrary to face-to-face smiles, which increase both ability and warmth, the smileys in a business e-mail had no effect on the perception（感知）of warmth, and in fact had a bad effect on the perception of ability. The perceptions of low ability in turn weakened information sharing.

    In another experiment, the use of a smiley was compared to a smiling or neutral photograph. The findings showed that in the case（情况）of a photograph, a smiling sender was judged to be more able and friendly than a neutral one. However, when an e-mail on formal work-related maters included a smiley, the sender was thought to be less able. The smiley did not influence the opinion on the sender's friendliness.

    “People are easy to accept that a smiley equals a real smile, but the findings of this study show that in the workplace, this seems not the case, especially when first communications are concerned.” Dr. Glikson says. “In such a situation, it is better not to use smileys to people at whatever age. Smileys could hardly be a wise choice to a person you are not familiar with.”

    Chinese are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter.

    However, what most parents fail to see is that the best early education they can give their children is usually very cheap. Parents can see that their children's skills vary, skilled in some areas while poor in others. What most parents fail to realize though, is that today's children lack self-respect and self-confidence. The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.

    Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.

    Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.

    Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them, trying to fix them; your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.

    A T-shirt that constantly monitors the heart's activity and detects abnormalities could help protect people against stroke. The T-shirt, which can be washed up to 35 times before it needs replacing, has been developed to improve the detection of dangerous heart conditions like atrial fibrillation( 心房颤动), which causes an irregular heart rhythm and raises the risk of stroke.

    At least one million people in Britain are known to have this condition; however, it's estimated that at least another 500,000 have it but haven't yet been diagnosed because they have no obvious symptoms. Some will have symptoms such as chest pain, dizziness and fatigue; but a large number of people have no idea they're ill until they suffer a stroke.

    Detecting atrial fibrillation involves carrying out an ECG(心电图). Conventional ECGs are done in a hospital and involve highly trained teams of staff attaching up to 24 separate electrodes(电极) to different parts of the body to measure electrical signals. But most patients experience abnormal rhythms only intermittently(间歇地). This means the chance of picking them up during a short hospital check is slim.

    Doctors sometimes issue patients with a device called a Holter monitor to wear under their clothes to try to pick up cardiac( 心脏的) problems. This is an electronic box which clips onto your waistband and is connected to a series of electrodes worn on the upper part of your body. But the box itself is quite bulky, hard to hide beneath clothing and involves a dozen or more wires being attached to the patient's chest.

    The Cardioskin T-shirt, which is made from cotton, could be a much more convenient alternative and can be worn 24 hours a day — meaning it is more likely to pick up any abnormal rhythms in the patient's heart. It has 15 tiny electrodes woven into the material which are strategically placed around the chest area to track the electrical signals from the heart as they travel across the main part of your body.

    The electrodes are powered by a battery which can be removed easily when you need to wash the T- shirt and feed results to a microchip which then sends them out wirelessly to an app. This converts( 转换) the data into an easy-to-read chart showing if the heart rate is abnormal. The results are shared with the patient's doctor so they can check the patient's heart without having to call them into the hospital.

    Martin Cowie, a professor of cardiology at Imperial College London, said, “Cardioskin could be an important development for cardiologists.”

    With smart technology increasingly influencing all aspects of our lives, it is only a matter of time before someone invents “smart” shoes—ones that can be made based on personal needs. Called “ShiftWear”, the sneakers are the brainchild of a team of businessmen, and engineers led by New York-based designer David Coel.

    The adaptable shoes can be customized by using a smart phone app. Shoe owners will have the option of selecting a design from a variety of HD pattern by famous artists or creating one themselves. The company's founders imagine a marketplace where artists can not only share but also sell their designs to others. Despite being electronic, the designs are clearly visible even in the brightest sunlight. What's even cooler is that by switching on a backlight, users can even show off their designs in the dark!

    According to Coel, the sneakers will keep their charge “forever” if only images are displayed. Though they will need periodic recharging, active users have nothing to worry about. That's because the shoes are equipped with special walk-n-charge technology that powers the shoes—with every step. Inactive users also have options of charging the sneakers without using wires.

    The bottom part of the shoes is covered with Kevler fibers, a kind of strong material, reducing normal wear and tear. Even better? They are completely waterproof (not let water through) and can even be thrown into an ordinary laundry machine for a quick wash! The company predicts that the shoes will range the price from $150 to $1000 depending on the size of the E-panels where the designs are displayed.

    This is not the first time that electronics and shoes have combined. Lithuania-based iShuh Technology has come up with a similar concept that connects e-reader panels to a smart phone app via the Bluetooth. Whether these smart shoes become as popular as our smart devices remains to be seen, though they surely are attractive.

    If you're tired of the big city pace and noise, relax yourself by taking a day or a weekend exploring one of these four Georgia small towns：

    Senoia

    About 45 miles from Atlanta, if you want to visit the classic small town, Senoia is the best choice. Built in 1866 as a railroad town, its picture perfection has been filmed for the movies like Fried Green Tomatoes.

    Hartwell

    109 miles from Atlanta

    Named for Nancy Hart, a heroine of the Revolutionary War who served as a spy and captured a group of Tories who threatened her home, Hartwell is known as the "Best city by a Dam Site".

    Tiger

    105 miles from Atlanta in northeast Georgia, this small mountain community sits at the base of 2 856-foot Tiger Mountain, and you can drive Old U. S. 441 right through town and into the countryside any season of the year. The tiny town itself boasts the Tiger Drive-In.

Another attraction is the Tiger Mountain Winery, operating from the site of a five-generation old family farm and winner of three 2017 silver medals in the Los Angeles Wine Competition. Its tasting room is open daily.

    Tallulah Falls

    About 96 miles northeast of Atlanta

    Near the Tallulah River and named for the five falls that flow downward very fast through the gorge, Tallulah Falls had a population of just 168 at the 2010 census.

    It's a fine spot for fishing and picnicking on the town's three lakes，swimming at the Georgia Power Company's Terrora Beach. Come Saturday night in spring，summer and folk stay for live Bluegrass bands on Bluegrass Square in downtown Tallulah Falls. You can even bring your own instrument and join in.

    Do's and Don'ts in Whale(鲸)Watching The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel (船只) operators follow these guidelines for all kinds of whales.

    Approach whales from the side, not from the front or the back.

    Approach no closer than 100 metres, then stop the boat but keep the engine on.

    Keep noise levels down-no horns. whistles or racing of engines.

    Start your boat only after the whales are more than 100 metres from your vessel.

    Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.

    Approach and leave slowly, avoiding sudden changes in speed or direction.

    Avoid disturbing groups of resting whales.

    Keep at low speeds and remain in the same direction if travelling side by side with whales.

    When whales are travelling close to shore, avoid crowding them near the shore or coming between the whales and the shore.

    Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.

    lf there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.

    Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.
