According to a recent study out of the University of Pennsylvania's Wharton School, men with shaved heads are considered to be more manly, powerful, and successful than those with longer hair or thinning(稀少的) hair. Besides, in some cases, they are considered to have greater leadership potential (潜力). That may explain why the power-buzz look has become popular among business leaders in recent years.

    Albert Mannes, Wharton management lecturer, said he was encouraged to do the research after noticing that he was treated with more respect when he shaved off his thinning hair.

    Mannes did three experiments to test people's impression of men with shaved heads. In one of the experiments, he showed 344 subject photos of the same men in two versions: one showing the men with hair and the other showing them with their hair digitally removed, so their heads appear shaved. In all three tests, the subject report found the men with shaved heads are more dominant(占优势的) than their hairy counterparts(对应的人).

    The study found that men with thinning hair were viewed as the least attractive and powerful. For those men, the solution could be as cheap and simple as a shave.

    New York image consultant Julie Rath advised her clients to get closely cropped when they start thinning up top. “There is something really strong, powerful and confident about laying it all bare(光秃的),” she said, describing the thinning look as kind of raunchy(不修边幅的).

    Not everyone needs a bare head. Rick Devine, 55, the CEO of Devine Capital Partners, advised executive candidates attracted by their clippers to keep their hair closely cropped, rather than completely shaved. “It is way too much image risk,” he said, “The best thing you can do in a business meeting is to make your look not an issue.”

    We just love giving cards in Britain. If there's a special occasion coming up, there's no doubt that we'll be there, card in hand, to celebrate it. And this isn't just for birthdays; we also give cards when people are ill or when they have got a new job. And even if you forgot somebody's birthday, there are even "sorry it's late" cards. So you can pretty much find a card for any occasion.

    Before coming to Italy I had never even considered that our love for card giving might not be shared by other countries. In fact, my workmates told me that hardly anyone sends Christmas cards in Italy and that they actually don't really give birthday cards either! Unbelievable! In the UK, if a close friend or family member didn't get me a card I'd feel upset! However, the only place you can buy cards in Italy is in a shop which sells school things. In comparison, we have whole shops that sell them in the UK and we even have different types of card shops.

    Although cards can take up your time, from choosing the perfect one, to thinking up the personal message inside, I think it's a really nice gesture. And especially with Christmas cards, it adds to that festive feeling. When I sit down to write countless cards to friends and family, I get that little bit happier that it will be Christmas soon! Especially when I see my own Christmas cards, proudly sitting on my desk wishing me a very merry Christmas.

    Of course, the problem comes when they're no longer needed, when Christmas is over. It makes me sad just to throw them all away, so I try and hang on to my favorite ones.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple — eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so-called similarity attraction theory — where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble (咬), while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions (交易) from the start.”

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”

    Dogs certainly need to bark (犬吠) every now and then, but if your neighbor's dog is getting in the way of your daily life, you need to do something.

    "Before you take action, you should record the dates and times that the barking happens to find out any patterns," says Schweitzer, who is a dog owner. You might notice the barking only happens when the owners are at work, or during thunderstorms.

    After two to three weeks of observing (观察), go to your neighbors with the facts. Wait for a time when the barking is over. "Since you're trying to keep a good relationship, you can't go when you're angry and upset," says Schweitzer. Besides, your neighbors might not even realize the barks are a problem, especially if the worst barking happens when they're not at home.

    Politely explain the times when the barking gets bad, and then suggest a way of solving the problem. Ask if the dog can stay inside during storms, or offer a dog training class.

    Making friends with the dog could help you gain some peace and quiet. If your neighbors introduce you to their dog, you should give the dog a treat. "If they become more comfortable seeing you, they're less likely to bark when they see you or when they're in the backyard，" says Schweitzer.

    Whatever you do, don't talk with your other neighbors about the problem or start a petition (诉状) to get the dog to quiet down. "Those make people feel angry," says Schweitzer. "That's when things escalate."

    If weeks go by and you still aren't seeing a difference, follow up with a note. Tie a dog treat on the note to build trust with your neighbors, and make a copy before dropping it off. That way, you'll have evidence (证据) that you've discussed it before and followed up politely if you need to bring in a third party, says Schweitzer.

    On Sunday, November 3, 2019, most North Americans will mark the end of Daylight Saving Time (DST) by moving their clocks back an hour. This simple action will not only add an extra 60 minutes to their weekend, but also shift (变换，变动) daylight back into the morning hours, making it a little less painful to wake up for school and work during the shorter winter days.

    Operating the clocks was first suggested by Benjamin Franklin in 1784. He mentioned the idea in a letter to the editor of the Journal of Paris and advised it should be a way to save candles, but it was not taken seriously. George Hudson from New Zealand also recommended moving the clocks back two hours in 1895 to get extra daylight time to study insects. Unfortunately, neither he nor British people William Willett, who suggested it in 1907 as a way to save electricity costs, got their wish.

    It was the German Empire that began the clock shifting tradition on April 30, 1916, to save fuel needed to produce weapons and bombs for World War I. Though a few others, including the US and Britain, adopted the tradition shortly after, all the countries returned to Standard Time once the war ended, only to start DST again during World War II. Once the battle ended in 1945, the US government ended DST nationally but allowed states and districts to continue the tradition and even allowed them to establish their own start and stop dates.

    However, though there have been many attempts to persuade lawmakers to end DST, both in the US and Europe, they have not been successful. Therefore, unless you live in places like Hawaii and Arizona, you have little choice but to "Fall Back" and enjoy the extra hour this weekend! Health experts suggest the best way to adjust is going to bed at your regular time, even if the day is an hour longer.

Despite extreme cold, cruel ice and being brushed off as mad, Slovenian Davo kamicar became the first person to ski non-stop down Mount Everest. After a dramatic fall over almost sheer cliffs of snow, stones and ice, 38-year-old Kamicar returned to his base camp after five hours of skiing. "I feel only absolute happiness and absolute tiredness," he said. 

Due to the severe weather conditions, Kamicar flung himself back down the mountain as soon as he reached the top rather than have a rest as planned At one point, he had to speed overstretches of ice that collapsed and broke underneath him and could have sent him falling into the deep crevasses(裂缝) that dot the mountain.

The descent (下落) had been widely regarded as extremely dangerous. The Darwin Awards website, known for documenting foolhardy deaths, urged people to log on to their website and "keep your eyes peeled for a live Darwin Award". However, the only body to make the news was the corpse (尸体)of an unknown mountaineer which Kamicar zipped past as he descended one of an estimated 120 corpses, thought to litter the slopes." This mountain is always full of surprises. Seeing a dead man out there was still a shocking experience," he said. 

Thanks to strategically placed cameras on the mountain and one attached to his safety helmet hundreds of thousands of people witnessed the process online, which was one of the record highs ever of more than 650,000 hits. The website was once jammed as people tried to access the site.

A previous failed attempt had already cost Kamicar two fingers when he got frostbite as a fierce storm hit the peak. Coming from a skiing family and had his first Himalayan skiing expedition in 1989, he has been ever since tireless in raising funds and sponsorship for more expeditions, with Everest as the permanent goal.
