A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19, 500 UK children born between 2000 and 2002 .The study was published in the Journal of Child Psychology and Psychiatry.

Findings showed that more children with ADHD came from families below the poverty line than the UK population as a whole, with average family incomes for households whose study child was affected by ADHD at £324 per week, compared to £391 for those whose child was not. The study found the odds (机会)of parents in social housing having a child with ADHD was roughly three times greater than for those who owned their own homes.

The team also found that the odds of younger mothers having a child with ADHD were significantly higher than for other mothers. Mothers with no qualifications were more than twice as likely to have a child with ADHD than those with degrees, and lone (孤独的)parents were more likely to have a child with ADHD diagnosis than households with two live-in parents.

Information was gathered from surveys when the cohort children were nine months old, and at the ages of three, five, seven and eleven.

Dr Ginny, of the University of Exeter Medical School,who led the study, said, "There is a genetic element to ADHD,but this study provides strong evidence that ADHD is also associated with a disadvantaged social and economic background. Some people believe that ADHD in children causes disadvantage to the economic situation of their family, but we found no evidence to support that theory. It's important to discover more about the causes of this disorder so that we can look towards prevention, and so that we can target treatment and support effectively. "

【推荐2】Yelp, the San Francisco Internet company that makes reviews of restaurants and other businesses across a large part of America, is getting into the food delivery business.

Today, the company has announced that it has agreed to acquire Eat24, a food company that delivers food to homes on behalf of partner restaurants. Yelp is paying $134 million for the company—$75 million in cash and the rest in stock. Eat24 works with 20,000 restaurants in more than 1,500 cities all over the U.S.

On Yelp's reviews site, you can find new restaurants to suit your tastes, and now that the company is acquiring Eat24, the idea is that it will also let you take the next step: order food to your door.

“If you're looking at a restaurant, you want to be able to book that restaurant,” Yelp co－founder and CEO Jeremy said in a Tuesday interview. “If we can integrate(融入) that into the Yelp experience, it makes the site much better.”

The move is just one way that some of Internet's most recognizable names are branching into online food delivery to improve their existing business. Last August, payments company Square bought Caviar, a high－end quick food delivery service. And that same month, Uber tested a fast food delivery service called UberFRESH, which aimed to deliver meals from local restaurants to customers in less than 10 minutes.

In each case, food delivery can provide an added source of income, and it can also help these companies push the use of their existing services. The market for food delivery is hardly small, and mobile technologies can speed up the process, potentially expanding the business even further.

A few of wanghong have been hired by luxury brands.Jaeger-LeCoultre, a Swiss watchmaker,hired Papi Jiang for a video ad targeting young urbanites(都市人），including her 27m fans on Sina Weibo,a Twitter-like microblog. Zhang Yi of iiMedia Research,a consulting firm,estimates that up to 15%of sales on shopping sites like Taobao or social-media apps such as WeChat are influenced by wanghong's public support.The length of a dress might be decided by a survey of a wanghong's fans;its launch date might be based on the number of hits,shares or comments it collects,some of which can cause last-minute design changes.

This poses a new challenge for retailers(零售商），whose supply chains must respond even more quickly to wanghong's opinions.Whereas previously a company would look for a celebrity to match its image,wanghong and their admirers are shaping goods.

Another challenge comes directly from wanghong themselves.They increasingly make money not merely from online support or advice but by launching their own e-commerce stores.Sales of goods accounted for just under half of wanghong earnings of 53bn yuan($8bn)in 2016,estimates Analysis,a Chinese market-research firm(the rest came mostly from live-show tips and adverts).

Some wanghong are going a step further.In November Becky Fang launched her own clothing line.Part of her motivation,she says,was that the brands she supported did not always match the trends she was sharing with her followers.By creating her own brand,Becky's Fantasy,she has full control of the quality.She also gains a new income. For the time being only 3-5%of wanghong follow Becky Fang's example,iiMedia Research estimates.But it expects the model to become an industry in its own right, including entertainment and e-commerce,and driven by online data..

【推荐1】Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text directly to the reader's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, bypassing traditional publishers and traders. But it also raises the possibility of mass piracy(盗版). Phil Rance, founder and managing director of Online Originals, a London-based e-book publisher, sums it up，“No one wants Napster to happen to books.”

Indeed, the most popular MP3 may have put the frighteners on an industry that generally operates some way behind the “bleeding edge”. The Meta Group, a leading US-based market researcher, says publishers are far too concerned about protecting their rights,“ We believe all the recent legal control over Napster is like putting a finger in a river that is already overflowing. Publishers need to deal with reality and come up with new ways to develop wide electronic distribution, asking the question, ‘How can we change the certainty of wide distribution to our advantage?’ ”

At the moment, most publishers would like to limit the use of e-books to the person who bought them, or to the computer used to download them. If that can be done, e-books become just an extra income stream in a publishing industry that would continue to operate the way it does today, according to Terry Robinson, business manager for the digital rights aspect, “you've cracked the market,” he says.

Robert Nichols, Books Director at BOL agrees, “Rights management is absolutely important. Publishers just say that, ‘until copyright is secure, we're not going to talk’．”

【推荐2】I have frequently taught Research Methods and Design to college students at several institutions. I love teaching this course. One reason, of course, is that I enjoy thinking about research methodology (方法学) and sharing it with others. The other reason, however, is the obvious impact that it has on students. Every term, one (if not more) student tells me how taking this course has affected him/her: “I used to just read articles and believe what they said, but now I find myself asking ‘Is this true? How do they know? Is this a well designed study?’ ” That is what I want the students to achieve in this course.

This brings to mind something written by Dorothy L. Sayers in 1948. One of her books, The Lost Tools of Learning speaks to Sayers’ thoughts on education. “By teaching our young men and women to read, we have left them at the mercy of the printed words. By the invention of the film and the radio, we have made certain that no dislike for reading shall protect them from the constant battery of words, words, words. They do not know what the words mean: they are victims to words in their emotions instead of being the masters of them in their intelligence.”

We are well past the 1940s, but her observation is still relevant. Sayers’ point is well taken. In the world of 24-hour news and social media that often resembles the Wild West, the ability to carry out evaluations has never been more important. In order to resist the distortions with which we are constantly bombed in the media, as well as be able to present a persuasive argument, we must be able to reason well, and think and give a judgement carefully.

When my students begin the Research Methods and Design course, they are generally not content to read all those research article I give. However, by the end of the course, they are excited about their newly obtained abilities.

【推荐3】Unlike Hillary Clinton, and most previous US presidents, who entered the election after years of being politicians, Trump, 70, the country’s 45th president, was a New York businessman. And he was not a presidential candidate who worked hard to keep a perfect public image(形象) of a man who was always caring, fair and intelligent. Instead, Trump has a reputation of being bad-tempered, self-important and hateful toward those who disagree with him. He also blames immigrants, both from Latin America and the Middle East, for many problems in the US. This has caused a dangerous division in the country —a country made up of many diverse races. Furthermore, he opposes globalization.

But to his supporters, the fact that Trump is not a typical politician is actually one of his advantages. His habit of never hiding his opinions is also considered by many to be a sign that he is not a pretender like many politicians are. “We have seen our country take a fall in the eyes of the world. We need to go in a different direction,” Binyom in Weisswasser, 39, a man from Chicago, told the Chicago Tribune. “Trump’s not a politician. I like that he is not always politically correct and speaks his mind. It gives me the feeling that what you see is what you get. You may not like it, but you know what it is.

But interestingly, many who voted for Trump actually followed the “lesser of two evils(两害相权取其轻)” principle—one that people use when faced with picking from two unpleasant options — simply because they didn't think Clinton was a better choice. “He’s the candidate I disagree less with,” Jack Stucky, 20, a student at Northwestern University, told the Chicago Tribune. “I don’t think I'd say Donald Trump is going to be the best president ever, but I did think he’d be better than Hillary Clinton.”

【推荐2】It is rightly said that one can share any secret with a true friend. He may know your deepest fears and weaknesses and yet will never take advantage of you. However, keeping a friend’s secrets to yourself and not telling the world is what makes the bond grow strong and last forever. You need to develop trust and mutual understanding before you start sharing secrets with each other. With friends, secret talks never seem to end and it can get really amusing to know what has been going on in your friend’s mind.

There is a certain time in life especially from the teenage years when one starts having a personal periphery in life and parents are excluded from it. It is because there are certain things that they can’t understand and we can’t discuss with them. That is when friends become the best secret sharers. They are the ones to whom one reveals one’s feelings and best kept secrets.

It is a general belief that only girls share secrets. But boys have their own secrets that they discuss with only closest friends. The secret talks can range from relationships, talks about fights with parents, secret activities and anything that is not supposed to be known to others! If you think secrets are limited to only teenagers, get your facts right! Secrets can be shared at any age and there is no hard and fast rule that secrets are shared only among youngsters.

Sharing secrets with a friend is not just fun, but it also helps to develop a lasting trust in one another. Sometimes, sharing secrets will tell you more about the person. You will come to know whether your friend is reliable and trustworthy and whether it is worth sharing your secrets with them. You can call it a test of friendship.

【推荐3】British historian Jacob Bronowski once wrote, “Man masters nature not by force, but by understanding.” This is especially for extreme climber Alex Honnold, who climbed California's El Capitan by himself, without any safety ropes(绳子), in 2017. The New York Times called it“one of the greatest athletic feats（功绩）of any kind, ever.”

Now you can watch him do it. The documentary Free Solo, which hit Chinese mainland cinemas on Sept 6, shows Honnold’s brave journey up the 914-meter high mountain. The film won the 2019 Academy Award for Best Documentary Feature in February. In it, Honnold gives us some useful advice:“You’ll always feel fear, but over time you’ll realize the only way to truly manage your fear is to broaden your comfort zone. It means that challenging yourself is important.”

In fact, free climbing requires perseverance, control, and concentration. “I’m not thinking about anything when I’m climbing,” Honnold said, “I’m focused on doing what’s in front of me.” This strong focus on the present is a sort of meditation (冥想) that we can use in our daily routines.

While the documentary seemingly praises extreme athletes for pushing the limits of human potential, some are concerned about Honnold risking his own life. “His deed puts great stress on his loved ones, even when he succeeds,” Climbing Magazine noted.

Free Solo seems to say that with enough courage and dedication, one can achieve any goal. However, the movie may also be viewed as the disturbing story of a climber who went against all better judgment and got away with it.

【推荐1】For as long as there have been gifts, we naturally make choices based on the recipient (接受者). But what if we have been wrong all along and that we could turn things around, which not only made gift buying easier, but the recipient happier?

In 2015, psychologists Lauren Human and Lara Aknin conducted an online survey, which suggested that when people buy gifts, they prefer to choose something based on the recipient’s personality and tastes. Most people also said that they preferred receiving gifts bought with them in mind: gifts for them.

But Human and Aknin wondered if this approach to giving failed to take advantage of the way we connect as people. So they sent 78 volunteers into a shopping centre before Mother’s Day. Half were told to buy a card that “reveals(揭示) your knowledge of the recipient” while the others set out to buy a card that “reveals your true self”. After the purchase, the givers who had thought partly of themselves reported feeling emotionally closer to their mothers.

To find out how that approach goes down with recipients, the psychologists did another test, asking more than 100 students to choose a song on iTunes to give to a friend, partner or family member. Each half of the group received the same instructions as the card buyers. Results revealed that recipients of songs that revealed something of the givers felt closer to them than those who received gifts bought only with them in mind.

Human and Aknin suggest it might apply to all gifts. “If building stronger social connections is the underlying (潜在的)goal” of a gift and surely it should be — then we “may well be advised to offer more self-reflective gifts”. In short, for a present to be meaningful, you need to give away a bit of yourself, even if there is a risk that the gift might not so closely suit the recipient’s practical needs or tastes as one acquired purely with that in mind.

Moreover, giving something of oneself can be a safer act, the psychologists added. Because it reduces the risk of revealing poor knowledge of a recipient by attempting to buy something that fits their character — and failing.

But a note of caution here: what the research does not examine is the potential risk in repeated, unsympathetic giver-centered giving, which, according to Human and Aknin “could signal self-obsession” — and nobody wants to reveal that about themselves.

【推荐2】2019 World Conference on VR Industry was held in Nanchang, China, with the goal of further satisfying people's growing demand for a better life, accelerating the modernization of China's economic system and its transformation into an innovation -oriented country, and promoting breakthroughs in the economic and social development of Jiangxi Province. The theme of the conference is "VR Adorns （装扮）the World - VR + 5 G for a New Era of Perception （观念）” .The virtual reality industry in Nanchang, capital city of East China's Jiangxi province, is expecting a boom when China grows in a new era of 5G this year, experts and industry insiders said at the conference.

The Conference attracted experts, scholars and company leaders from more than 30 countries, including the US, Germany, Britain, Russia, India and Israel, discussing the development and application of VR, especially as 5G, the next generation technology for network on devices like cellphones, unlocks the potential of VR. With a focus on the new era of perception enabled by 5G, this yearns conference showed leading-edge VR technologies and the latest outcomes of the global VR industry.

Miao Wei, head of the Ministry of Industry and Information Technology, said in the opening address that with China officially getting 5 G commercial licenses on June 6th 2019, the co — development of VR and 5G promises a huge market in future. " China takes the lead in VR innovations. And the wide popularity of high-tech in our country guarantees the potential of this market, said Miao.

China is building its VR industry into one with the most dynamic environments for innovation and entrepreneurship, highest market acceptance, and the greatest growth potential in the world.

【推荐3】There are two kinds of secrets: secrets of nature and secrets about people. Natural secrets exist all around us; to find them, one must study some undiscovered aspect of the physical world. Secrets about people are different: they are things that people don't know about themselves or things they hide because they don't want others to know. So when thinking about what kind of company to build, there are two distinct questions to ask: What secrets is nature not telling you? What secrets are people not telling you?

It's easy to assume that natural secrets are the most important: the people who look for them can sound authoritative (权威的).This is why physics PhDs are difficult to work with—because they know the most basic truths, they think they know all truths. But does understanding electronic theory automatically make you a great marriage counselor? Does a gravity theorist know more about your business than you do? At PayPal, I once interviewed a physics PhD for an engineering job. Halfway through my first question, he shouted, "Stop! I already know what you're going to ask!" But he was wrong. It was the easiest no-hire decision I've ever made. Secrets about people are relatively overlooked. Maybe that's because you don^,t need a dozen years of higher education to ask the questions that uncover them: What are people not allowed to talk about? What is forbidden or taboo?

The best place to look for secrets is where no one else is looking. Most people think only in terms of what they've been taught; schooling itself aims to spread basic wisdom. So you might ask: are there any fields that matter but haven't been standardized? Physics, for example, is a real major at all major universities, and it's set in its ways. The opposite of physics might be astrology, but astrology doesn't matter. What about something like nutrition? Nutrition matters for everybody, but you can't major in it at Harvard. Most top scientists go into other fields. Most of the big studies were done 30 or 40 years ago, and most are seriously flawed (有缺陷的).The food pyramid that told us to eat low fat and large amounts of grains was probably produced by Big Food(美国著名食品公司)than real science; its chief impact has been to worsen our obesity(肥胖)problem. There^’s plenty more to learn: we know more about the physics of far away stars than we know about human nutrition. It won't be easy, but it's not obviously impossible: exactly the kind of field that could produce secrets.
