1 . On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.
But a new study led by Joaquin Navajas offered an interesting twist (转折) on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.
In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn’t the dominant response. Most frequently, the groups reported that they “shared arguments and reasoned together”. Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.

2 . As cities balloon with growth, access to nature for people living in urban areas is becoming harder to find. If you’re lucky, there might be a pocket park near where you live, but it’s unusual to find places in a city that are relatively wild.
Past research has found health and wellness benefits of nature for humans, but a new study shows that wildness in urban areas is extremely important for human well-being.
The research team focused on a large urban park. They surveyed several hundred park-goers, asking them to submit a written summary online of a meaningful interaction they had with nature in the park. The researchers then examined these submissions, coding (编码) experiences into different categories. For example, one participant’s experience of “We sat and listened to the waves at the beach for a while” was assigned the categories “sitting at beach” and “listening to waves.”
Across the 320 submissions, a pattern of categories the researchers call a “nature language” began to emerge. After the coding of all submissions, half a dozen categories were noted most often as important to visitors. These include encountering wildlife, walking along the edge of water, and following an established trail.
Naming each nature experience creates a usable language, which helps people recognize and take part in the activities that are most satisfying and meaningful to them. For example, the experience of walking along the edge of water might be satisfying for a young professional on a weekend hike in the park. Back downtown during a workday, they can enjoy a more domestic form of this interaction by walking along a fountain on their lunch break.
“We’re trying to generate a language that helps bring the human-nature interactions back into our daily lives. And for that to happen, we also need to protect nature so that we can interact with it,” said Peter Kahn, a senior author of the study.

3 . Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.
Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.
That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately."
"Big change requires big ideas." he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.
An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws.
"We need something on the books that can change people's behavior,” said Félix W. Ortiz, who pushed for the state's 2001 ban on hand-held devices by drivers. If the Textalyzer bill becomes law, he said, "people are going to be more afraid to put their hands on the cell phone."

4 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?

6 . I have worked as a keeper at the National Zoo, Paris for 11 years. Spot and Stripe are the first tiger cubs that have ever been born here. Globally, a third of Sumatran cubs in zoos don't make it to adulthood, so I decided to give them round-the-clock care at home.
I've got two children—the younger one, Kynan, was extremely happy about the tigers arriving - but all of us really looked forward to being part of their lives and watching them grow. I wasn't worried about bringing them into my home with my wife and kids. These were cubs. They weighed about 2.5 kg and were so small that there was absolutely no risk.
As they grew more mobile, we let them move freely around the house during the day, but when we were asleep we had to contain them in a large room, otherwise they'd get up to mischief. We'd come down in the morning to find they'd turned the room upside down, and left it looking like a zoo.
Things quickly got very intense due to the huge amount of energy required to look after them. There were some tough times and I just felt extremely tired. I was grateful that my family was there to help. We had to have a bit of a production line going, making up “tiger milk”, washing baby bottles, and cleaning the floors.
When Spot and Stripe were four months old, they were learning how to open doors and jump fences, and we knew it really was time for them to go. It was hard for us to finally part with them. For the first few days, Kynan was always a bit disappointed that the cubs weren't there.
I'm not sad about it. I'm hands-on with them every day at the zoo, and I do look back very fondly on the time that we had them.

9 . Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills.
Psychologist Susan Levine, an expert on mathematics development in young children at the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income, education and the amount of parent talk, Levine said.
The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age.
“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.
The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.
The findings were published in the journal Developmental Science.

10 . For Western designers, China and its rich culture have long been an inspiration for Western creative.
“It’s no secret that China has always been a source(来源) of inspiration for designers,” says Amanda Hill, chief creative officer at A+E Networks, a global media company and home to some of the biggest fashion(时尚) shows.
Earlier this year, the China Through A Looking Glass exhibition in New York exhibited 140 pieces of China-inspired fashionable clothing alongside Chinese works of art, with the aim of exploring the influence of Chinese aesthetics(美学) on Western fashion and how China has fueled the fashionable imagination for centuries. The exhibition had record attendance, showing that there is huge interest in Chinese influences.
“China is impossible to overlook,” says Hill. “Chinese models are the faces of beauty and fashion campaigns that sell dreams to women all over the world, which means Chinese women are not just consumers of fashion — they are central to its movement.” Of course, not only are today’s top Western designers being influenced by China—some of the best designers of contemporary fashion are themselves Chinese. “Vera Wang, Alexander Wang, Jason Wu are taking on Galliano, Albaz, Marc Jacobs—and beating them hands down in design and sales,” adds Hill.
For Hill, it is impossible not to talk about China as the leading player when discussing fashion. “The most famous designers are Chinese, so are the models, and so are the consumers,” she says. “China is no longer just another market; in many senses it has become the market. If you talk about fashion today, you are talking about China—its influences, its direction, its breathtaking clothes, and how young designers and models are finally acknowledging that in many ways.”
