Imagine that you're looking at your company-issued smartphone and you notice an e-mail from Linkedln:“These companies are looking for candidate like you!” You aren't necessarily searching for a job, but you're always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We've noticed that you're spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you're happy here,” she says Uh-oh.

    It's an awkward scene. Attrition(损耗) has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are making greater efforts to predict which workers are at high risk of leaving so that managers can try to stop them. Methods range from electronic monitor to sophisticated analyses of employees' social media lives.

    Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don't like their boss, don't see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.

    New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at when. “We've learned that what really affects people is their sense of how they're doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB's HR practice. “We've learned to focus on moments that allow people to make these comparisons.”

    Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun tracking badge swipes(浏览痕迹)—employees' use of an ID to enter and exit the building or the parking garage—to identify patterns that suggest a worker may be interviewing for a job.

    Spain is a country that lies in southwestern Europe. It's surrounded by the Mediterranean Sea on the south and the east, while to the north of Spain lie France, Andorra and the Bay of Biscay. The west and northwest of Spain are surrounded by Portugal and the Atlantic Ocean.

    The official name of the state is the Kingdom of Spain. Madrid is the capital city, which is also one of the famous places in Spain. Spain, which covers 506,000 square kilometers, is one of the largest countries in Europe.

    The weather in Spain differs from one area to another. Most of the rain that happens in Spain is in the mountainous areas. The plains hardly receive any rainfall.

    Soccer in Spain is an important part of life of the people in Spain. It's said that Spanish children learn to walk and play soccer at exactly the same time. Real Madrid and FC Barcelona are two Spanish soccer teams, which are respected by soccer fans not only in Spain, but all over the world. The popularity of the sport can be judged from the fact that three major soccer teams, which are Real Madrid, Atletico de Madrid , and Rayo Vallecano, were born in Madrid.

    If you are a tourist, then you would want to know about the driving rules in Spain. If you're not from the European Union, Switzerland, Norway, Iceland, or Liechtenstein, then for you to drive you'll have to carry your international driver's license. Bad news if you haven't celebrated your 18th birthday. If you want to rent a car, then you must have completed 21 years of age. If you're driving, make sure you carry all the documents on you at all times during your stay in Spain.

    Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won't be able to buy it now. “We're working to build the world's most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”

    Google's software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle's self-driving functions is a series of cameras, radars and sensors on the car's roof, which detect everything nearby from other vehicles and passers-by to cyclists.

    Kraft stressed that Google's cars aren't connected—they don't need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”

    Google's system has a major advantage over the semi-autonomous（半自主的）systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.

    China is fondly remembering one of its most famous radio voices, a man whose vivid storytelling was a comfort to millions of people, from commuters stuck in traffic to restless teens struggling to sleep. Shan Tianfang, was a leading performer of the traditional Chinese art form pingshu, which translates as "storytelling".

    Pingshu dates from the Song Dynasty (AD960-1279) when performers would entertain villagers by telling stories in a particularly emotive style. It remains particularly popular in north-eastern China. Performers wear traditional dress and use very basic props - often a folded fan and a gavel. Pingshu is sometimes performed in tea houses and small theatres, but many Chinese associate the art form with radio. And in a country where sleeping problems are commonplace, pingshu is still popular as a way of helping people to wind down at bedtime.

    Shan Tianfang was born in 1934 in Yingkou, in north-eastern Liaoning province. His family introduced him to folk arts from a young age and he began learning pingshu when he was 19. He became known in Liaoning for his work on stage and in local teahouses during the 1950s and 1960s, and performed in an art troupe around the region. From 1966-1976, Shan, along with other pingshu performers like Yuan Kuocheng, was forced to stop work. During the 1980s.Shan made the transition (转型) to state-run radio, and his captivating storytelling became comfort listening for people across the country. By the 1990s, Shan had become a well-known face on state TV, even performing in the annual Spring Festival Gala show. He has died aged 84 following a long illness.

    Shan performed over 12,000 stories on TV and radio. His stories attracted people of all ages. One of his most acclaimed performances is of the Heroes in the Sui and Tang Dynasties. He gave countless performances of the “Four Classic Novels” (Romance of the Three Kingdoms, Journey to the West, Dream of the Red Chamber and Water Margin) and also helped to bring lesser-known classical Chinese literature to new audiences.

    He was able to use the medium to entrance his audience and in the process he helped to popularise classical Chinese literature. As film director Zhang Jizhong told the Global Times newspaper: “He could describe a scene and a character extremely vividly. He once had a long talk with me about adapting the heroic stories he told into films or television shows to help promote Chinese classics and traditional culture.”

    But in his later years, the growth of online and digital media exposed the challenges of keeping his art form alive. Shan turned his efforts towards writing books and opening performance schools to teach pingshu to young people. They included the Shan Tianfang Culture and Media Academy in Beijing, a Shan Tianfang teahouse and “storytelling base” in Anshan in Liaoning province. Meanwhile, modern productions of pingshu reference (引用，参照) contemporary  (现代的) culture to draw in new performers and audiences. Performers like Guo Heming have emerged, putting a modern spin on pingshu by adapting popular works, including the Harry Potter stories.

    Although he wasn't particularly active on social media, he amassed more than one million fans on the Sina Weibo platform.

A memorial was held for him on 15 September but millions of Chinese will miss his voice.
