The world's first robot police officer has started working. Its name is 'RoboCop' and it went into service for the Dubai Police earlier this week. Robocop's first official duty was to greet guests at the opening of a security conference in Dubai. Apart from greeting visitors' its job was to answer questions and give directions. RoboCop has a built — in tablet for people to interact with. People can use the tablet to pay traffic fines and use other smart police services. The tablet is linked to a police station, so people can talk to human police officers. In addition, RoboCop can speak six languages, including English and Arabic. The 170 - centimetre - tall robot can also shake hands, salute people and recognize people's emotions and facial expressions.

    Dubai Police says RoboCop is the first of many robot police officers for the city. A spokesman said that by 2030, 25 per cent of the Dubai Police force will be robots. He said: “We are looking to make everything smart in Dubai Police. By 2030, we will have the first smart police station which won't require human employees.”

    “The RoboCop is the latest smart addition to the police force and has been designed to help us fight crime, keep the city safe and improve happiness levels,” He added. He also said that RoboCop would, “assist and help people in the malls or on the streets”. An official at the security conference commented that the future is here now, saying: “The age of the robots is no longer coming. It has arrived.”

    "A photograph that one has taken of oneself, typically with a smart phone or webcam and uploaded to a social media website" is the definition of "selfie" in the Oxford English Dictionary. In fact, it wasn't even in the dictionary until August of last year. It earned its place there because people are now so obsessed with (对……痴迷) selfies—we take them when we try on a new hat, play with our pets or when we meet a friend whom we haven't seen in a while.

    But is there any scientific explanation for this obsession? Well, you should probably ask James Kilner, a neuroscientist(神经系统科学家) at University College London.

    Through our lifetime we become experts at recognizing and interpreting other people's faces and facial expressions. In contrast, according to Kilner, we have a very poor understanding of our own faces since we have little experience of looking at them—we just feel them most of the time.

    This has been proved in previous studies, according to the BBC.

    Kilner found that most people chose the more attractive picture. This suggests that we tend to think of ourselves as better-looking than we actually are. To further test how we actually perceive our own faces, Kilner carried out another study. He showed people different versions of their own portrait—the original, one that had been edited to look less attractive and one that was made more attractive—and asked them to pick the version which they thought looked most like them. They chose the more attractive version.

    But what does it say about settles? Well, isn't that obvious? Selfies give us the power to create a photograph—by taking it from various angles, with different poses, using filters (滤色镜) and so on—that better matches our expectations with our actual faces.

    "You suddenly have control in a way that you don't have in non-virtual(非虚拟的) interactions," Kilner told the Canada-based CTV News. Selfies allow you "to keep taking pictures until you manage to take one you're happy with", he explained.

    With its snow-covered mountains and a variety of wildlife, Yellow Stone National Park is one of the scenic treasures of the United States. Located primarily in Wyoming, the park hosts millions of visitors every year. If you plan to travel within the park, keep in mind advice from the National Park Service.

    Seasonal Travel

    Travel varies vastly from season to season. Roads are generally open in the summer except for cases of rock or mud slides, wild fires, accidents or road construction. Early snows in the fall can cause some roads to close temporarily. In the winter almost all roads are closed to motor vehicles, but snowmobiles and other snow vehicles with tracks are allowed. Roads begin to open for the spring by the latter part of April but can close if snowfall continues.

    Driving Time

    Grand Loop is the main road through Yellowstone National Park; it passes by most of the major attractions. These include Old Faithful, Yellowstone Lake and the Grand Canyon of Yellowstone. The maximum speed limit on the Grand Loop is 45 miles per hour, but the speed limit drops during some of the winding and twisting sections of this narrow road. Allow yourself at least two days to fully travel the loop due to the size of the park and being sometimes stuck in heavy traffic.

    Safety Awareness

    Buffalo(水牛)often block the roads in the park as they move through the fields. If a group is traveling across the road you are on  you can either wait for them to pass or find an alternative route. If you get out of your vehicle, the National Park Service says to stay at least 25 yards from any buffalo (and 100 yards or more away from bears and wolves). Buffalo are particularly unpredictable and charge people at speeds up to 30 mph.

    You can take your bicycle on any public roads and routes designed for bikes, but bicycles are not allowed on the park roads which are narrow with few shoulders. Altitudes range from 5, 300 to 8, 860 feet. The National Park Service recommends cyclists wear helmets and noticeable clothing.

    A fresh and gentle wind on your face, soft sand under your feet and blue waters as far as the eye can see. Is there any other Olympic sport that is played in such pleasant conditions as beach volleyball?

    "I've gone to a lot of beautiful places, and met a lot of beautiful people. That wouldn't have happened if I had been playing another sport," said Randy Stoklos, America's most famous beach volleyball player.

    The sport began as a four-a-side game on beaches in Southern California in the 1920s.The first recorded two-man game took place there in 1930, and the first tournament was held in Los Angeles 18 years later. The winners were awarded a case of Pepsi. In the 1950s, women started playing and the sport soon spread to Europe and South America. Yet at that time, beach volleyball was more an entertainment show than a sport, with beauty contests included. The Association of Volleyball Professionals was founded in 1983 and beach volleyball developed into a fast, athletic sport. Its world-wide popularity won beach volleyball a place at the 1996 Olympics in Atalanta, where 24 male teams and 16 female teams took part. At present, the US and Brazil are the best in the world at beach volleyball.

    The game came to China in the early 1990s and there have been national tournaments since 1994. It became an official event at the Eighth National Games in 1997.China's You Wenhui and Wang Lu finished ninth in the women's beach volleyball world championships in Brazil.

By now you've probably heard about the "you're not special" speech, when English teacher David McCullough told graduating seniors at Wellesley High School: "Do not get the idea you're anything special, because you're not." Mothers and fathers present at the ceremony — and a whole lot of other parents across the Internet — took issue with McCullough's ego-puncturing words. But lost in the uproar was something we really should be taking to heart: our young people actually have no idea whether they're particularly talented or accomplished or not. In our eagerness to elevate their self-esteem, we forgot to teach them how to realistically assess their own abilities, a crucial requirement for getting better at anything from math to music to sports. In fact, it's not just privileged high-school students: we all tend to view ourselves as above average.

Such inflated self-judgments have been found in study after study, and it's often exactly when we're least competent at a given task that we rate our performance most generously. In a 2006 study published in the journal Medical Education, for example, medical students who scored the lowest on an essay test were the most charitable in their self-evaluations, while high-scoring students judged themselves much more strictly. Poor students, the authors note, "lack insight" into their own inadequacy. Why should this be? Another study, led by Cornell University psychologist David Dunning, offers an enlightening explanation. People who are incompetent, he writes with coauthor Justin Kruger, suffer from a "dual burden": they're not good at what they do, and their very incapability prevents them from recognizing how bad they are.

In Dunning and Kruger's study, subjects scoring at the bottom of the heap on tests of logic, grammar and humor "extremely overestimated" their talents. What these individuals lacked (in addition to clear logic, proper grammar and a sense of humor) was "metacognitive skill": the capacity to monitor how well they're performing. In the absence of that capacity, the subjects arrived at an overly hopeful view of their own abilities. There's a paradox here, the authors note: "The skills that lead to competence in a particular domain are often the very same skills necessary to evaluate competence in that domain." In other words, to get better at judging how well we're doing at an activity, we have to get better at the activity itself.

There are a couple of ways out of this double bind. First, we can learn to make honest comparisons with others. Train yourself to recognize excellence, even when you yourself don't possess it, and compare what you can do against what truly excellent individuals are able to accomplish. Second, seek out feedback that is frequent, accurate and specific. Find a critic who will tell you not only how poorly you're doing, but just what it is that you're doing wrong. As Dunning and Kruger note, success indicates to us that everything went right, but failure is more ambiguous: any number of things could have gone wrong. Use this external feedback to figure out exactly where and when you screwed up.

If we adopt these strategies — and most importantly, teach them to our children — they won't need parents, or a commencement (毕业典礼) speaker, to tell them that they're special. They'll already know that they are, or have a plan to get that way.
