Kathy Fletcher and David Simpson have a son named Santi. He had a friend who sometimes went to school hungry. So Santi invited him to occasionally eat and sleep at his house.

    That friend had a friend and that friend had a friend, and now when you go to dinner at Kathy and David's house on Thursday night there might be 15 to 20 teenagers gathering around the table, and later there will be groups of them crashing in the basement or in the few small bedrooms upstairs. The kids who show up at Kathy and David's have suffered the pains of modern poverty: homelessness, hunger, abuse.

    And yet by some miracle, hostile soil has produced beautiful flowers. Kids come from around the city. Spicy chicken and black rice are served. Cellphones are banned. The kids who call Kathy and David “Momma” and “Dad,” are polite and clear the dishes. Birthdays and graduations are celebrated. Songs are performed. Each meal we go around the table and everybody has to say something nobody else knows about them. Each meal the kids show their promise to care for one another.

    The adults in this community give the kids the chance to present their gifts. “At my first dinner, Edd read a poem that I first thought was from Langston Hughes, but it turned out to be his own. Kesari has a voice that somehow appeared from New Orleans jazz from the 1920s. Madeline and Thalya practice friendship as if it were the highest art form.”

    “They give us a gift — complete intolerance of social distance. When I first met Edd, I held out my hand to shake his. He looked at it and said, “We hug here,” and we've been hugging since.”

    Bill Milliken, a veteran youth activist, is often asked which programs turn around kids' lives. “I still haven't seen one program change one kid's life,” he says. “What changes people is relationships. Somebody is willing to walk through the shadow of the valley of adolescence with them.” Souls are not saved in bundles. Love is the necessary force.

    Why is pink or purple a color for girls and blue or brown for boys?

    The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils（灾祸）.

    People's choice of colors is also influenced by their bodies' reactions （反应）toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomach aches.

    Red can cause a person's blood pressure to rise and increase people's appetites（食欲）. Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person's eye.

    Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.

    The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

    Thousands of taxi drivers in Shenyang, Liaoning Province, reportedly blocked streets with their vehicles on Sunday in protest against unlicensed vehicles using taxi-hiring apps(打车软件) and apps-based car rental companies providing passenger services, including high-end cars. Although the drivers also complained about the withdrawal of the fuel subsidy (补贴) by the government, their main complaint was the loss of business because of the rising number of Internet-based car services companies.

    On Wednesday, news reports came that Beijing transport authorities will take measures to stop the illegal “taxi business” of private cars through the newly rising Internet apps, following the footsteps of Shenyang and Nanjing.

It is not yet clear how the Shenyang city government will handle the issue and whether it will declare the services offered by market leaders such as Didi Dache, a taxi-hiring app provider backed by Tencent Holdings, and Kuaidi Dache illegal. But Shanghai transport regulators have set a rule, by banning Didi Zhuanche, or car services offered by Didi Dache in December.

    Such regulations will cause a setback to the car-hiring companies and investors that are waiting to cash in on the potentially booming business. Just last month, Didi Dache got $700 million in funding from global investors, including Singapore state investment company Temasek Holdings, Russian investment company DST Global and Tencent. Besides, the market is uncertain that Kuaidi Dache is about to finalize its latest round of funding after getting $800 million from global investors.

    Regulatory uncertainties, however, could cast a shadow on the future of the Internet-based car-hiring services, which have become popular in most of China's big cities. To be fair, these companies' business model is anything but bad. For example, Didi Zhuanche works side by side with established car rental companies to provide high-end car service mainly for businesspeople through the Internet and mobile phone apps.

    Every link in this business model chain has legal companies and services. Therefore, it is hard to define it as illegal and ban it.

Do you think you would work out more if you were offered money to do so? Science has shown that money can give people motivation to work out, but perhaps not in the way that you think.

According to a study published in the Annals of Internal Medicine Journal, the best strategy isn't offering money; it's giving someone money, then threatening to take it away.

Researchers gave 281 people the goal of walking 7,000 steps every day over 13 weeks.

To motivate the people who took part to reach the goal, researchers divided them into three groups.

People in the first group received $1.40(9 yuan) each day as long as they finished 7,000 steps, the second group was only able to collect the $1.40 if they had reached 7,000 steps the day before, and the third group was given $42 at the beginning of each month and $1.40 was taken away every time someone failed to meet the goal.

The third group met their daily fitness goals 50 percent more often than the other two groups, showing that people were most motivated to walk by the fear of losing money.

    “People are more motivated by losses than gains, and they like immediate gratification.” study author Dr Mitesh Patel, an assistant professor at the University of Pennsylvania in the US, told CNN. “They want to be rewarded today, not next year or far into the future.”

    Our brains tend to avoid wanting to lose things more than they try to get the benefits from gaining them, Patel explained. “It makes people think like the money is theirs to lose from day one.”

In addition, in most programs, many participants will drop out quickly and only the motivated will stay involved, Patel said.

    “In ours, we were pleasantly surprised that 96 percent stayed.” he added.

The study provides evidence that what matters is not only the money incentive （激励）, but also how you think about them. This is important to how effective they are. The evidence could have a big effect on health promotion programs in the future, according to the study.

“Incentives themselves are not all you need,” Stephanie Pronk, a health and wellness consultant with the Aonplc corporation, told The Wall Street Journal. “It's really important to change up the incentive design and keep people on their toes.”

    Consumer electronics once again topped the list of the most wanted gifts this holiday season.

    "Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money or buy at least one technology product; definitely a solid vote of confidence for technology."

    Steve Koenig is with the Consumer Electronics Association. He says the group's latest research also shows that Americans this year are spending more on technology products. "Here in 2012, $252 on average the technology spend for consumers this year."

    From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. "It's kind of hard to make a decision."

    Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple's biggest competitors is the Google Nexus 7. It starts at $199.

    "Its hardware is more powerful than what's in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple's maps.

    But Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. "If you just want to read books and surf the Internet, you don't really need to get an iPad Mini, but if you want the largest robust group of apps (应用软件) that's where the iPad and Apple's ecosystem shines the most."

    Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through Wi-Fi. This makes it easy for users to email or upload photographs directly from the camera." You can literally take a picture and upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things."

    Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.
