WeChat is a social mobile application with voice and text messaging timeline and several social features like ‘Message in a Bottle'. WeChat, a popular instant messaging tool run by Tencent Holdings, aims to help users access mobile services without downloading separate apps, which experts said may challenge the business of smartphone app distributors such Apple Store.

This new feature, named ‘Mini Programs', allows WeChat users to find a variety of services such as ticket buying by scanning a QR (quick-response) code, saving them the trouble of installing a number of different apps on smart devices, according to the transcript of a speech by Zhang Xiaolong, Tencent's senior executive vice president, on Wednesday. The new function is expected to come online on January 9.

    Zhang, known as the father of WeChat, emphasized that ‘Min Programs' is not a mobile app distributing function.

    Still, experts and app developers said that the rollout (推出) of ‘Mini Programs' on WeChat will erode the market share of app distributors like Apple Store in China.

     “‘Mini Programs' will attract lots of start-ups, because a program based on WeChat can help them build up businesses at much lower costs,” a Shanghai-based app developer, told the Global Times Wednesday.

    If a start-up wants to promote its business via a separate application, it has to hire a special team to develop two different apps— one each for iOS and Android.

    Lsiunched in 2011, WeChat has evolved to include services such as ‘Order Taxi', ‘Food Delivery', e-commerce and payments from just an instant messaging app.

    As if 2016 hadn't been hard enough for China's workforce, a yearly survey has revealed that more than half of the country's white-collar employees got no year-end bonus ahead of the upcoming and costly lunar(农历的) New Year holiday. The survey of 11,500 workers by Chinese employment agency Zhaopin found that 50.9 per cent did not get an annual bonus at the end of 2016. Another 9.6 percent were told their bonuses had been delayed until after the New Year holiday.

    Before the slowdown that began in 2014, employers in China had been less ungenerous with cash bonuses, which can total well over a full month's pay and send employees back home for the holiday with plenty of cash for gifts to elders and other family members or to put away as savings. The impact of weak growth on year-end bonuses may have reached the highest point in 2015, however, when 66 per cent of white-collar workers received no year-end bonuses. And the 2016 level actually represents an improvement from 2014, when 61 per cent had to go without.

    But that recovery has also seen the size of bonuses drop: last year the average bonus was Rmb 12,821（$1,861）, about Rmb 2,000 more than that in 2015 but still about Rmb800 below the 2014 average. More than a quarter of those surveyed who saw their bonuses drop last year blamed the drop on poor company performance.

    Differences among the 34 cities surveyed were still greater, as the average bonus of over Rmb 15,800 in Beijing was more than three times than that in the lowest-paying city of Shenyang. Employees of state-owned firms also expressed more satisfaction with their bonuses than those at private companies — and little wonder, as the average bonus at the former was Rmb 17,318, or about Rmb 6,000 more than what private companies' employees could expect.

    But the impact of companies' stinginess(吝啬) can go beyond simply ruining employees' New Year holiday, possibly coming back to affect employers: 39 percent of respondents said they would look for work elsewhere if their year-end bonus was not returned to normal, an increase of 2.3 Percentage points from 2015.

    People are less willing to rely on their knowledge and say they know something when they have access (接近) to the Internet, suggesting that our connection to the web is affecting how we think.

    Professor Evan Risko, of the Department of Psychology at the University of Waterloo, led a recent study where the team asked about 100 participants (参与者) a series of general-knowledge questions, such as naming the capital of France. For half of the study, participants had access to the Internet. They had to look up the answer when they responded that they did not know the answer. In the other half of the study, participants did not have access to the Internet.

    The team found that the people who had access to the web were about 5 percent more likely to say that they did not know the answer to the question. Furthermore, in some cases, the people with access to the Internet reported feeling as though they knew less compared to the people without access.

    “With the popularity of the Internet, we are almost frequently connected to large amounts of information. And when that data is within reach, people seem less likely to rely on their own knowledge,” said Professor Risko.

    Studying the results, the researchers thought that access to the Internet might make it less acceptable to say you know something but are incorrect. It is also possible that participants were more likely to say they didn't know an answer when they had access to the web because online searching offers an opportunity to confirm their answer, and the process of finding out the answer is rewarding.

    “Our results suggest that access to the Internet affects the decisions we make about what we know and don't know,” said Risko. “We hope this research helps us understand how easy access to large amounts of information can influence our thinking and behaviour.”

    Antarctica(南极洲)'s melting ice, which has caused global sea levels to rise by at least 13.8 millimeters over the past 40 years, was thought to primarily come from the unstable West Antarctic Ice Sheet(WAIS). Now, scientists have found that the East Antarctic Ice Sheet (EAIS)—considered largely unaffected by climate change—may also be melting at an unexpectedly rapid speed.

    The WAIS, whose base is below sea level, has long been considered the most likely to break down. Besides gravity, a deep current of warm water slips beneath the sheet, melting it from below until it becomes a floating shelf at risk of breaking away. In contrast, extreme cold and a base mostly above sea level are thought to keep the EAIS relatively safe from warm waters.

    But as greenhouse gases warm much of the planet, driving stronger polar winds, some scientists think warm water carried by a circular current will start to invade East Antarctica's once unassailable ice. A cooperation of more than 60 scientists last year, published in Nature, estimated that the EAIS actually added about 5 billion tons of ice each year from 1992 to 2017.

    Eric Rignot of the University of California, Irvine, and colleagues combined 40 years of satellite imagery and climate modeling and found that overall Antarctica now sends six times more ice into the sea each year than it did in 1979, with the majority coming from West Antarctica. But East Antarctica was responsible for more than 30% of Antarctica's contribution to the 13.8-millimeter sea level rise over the past 40 years. “The more we look at this system the more we realize this is fragile,” Rignot says. “Once these glaciers become unstable there is no red button to press to stop it.”

    Rignot hopes the study brings greater attention to a part of Antarctica that has traditionally been understudied. Helen Fricker, a glaciologist (冰川学家) in California, agrees. “We need to monitor the entire Antarctica and we just can't do that without international cooperation.”

The True Story of a Young Man

When Reginald Lindsay received a scholarship to Morehouse College in Atlanta, Georgia in 1967, what he wanted most was not a job with a good salary, but a chance to be a member of Congress as a southern representative. After earning his degree at Harvard Law School in 1970, he returned to the South to practice law among the poor. "I want to help them understand what their rights are and to help them achieve them," he said. Then he ran for political office at the local and state level until he was ready to try for Congress.

Reg grew up in a low-income Negro section of Birmingham, Alabama. Brought up by his grandparents after his parents were divorced while he was very young, Reg had been living through a period of far-reaching progress in race relations. In the summer of 1968 Reg himself became a good example of this progress when he became the first Negro student appointed to a special new program. The program introduced bright young students to the workings of the Georgia State government and encouraged them to seek employment there after finishing their education. "I've been lucky," he said. "I seem to have been in the right place at the right time."

But luck was only part of Reg's story, for he made the most of opportunities that came his way. He learned to read in kindergarten and began visiting the public library regularly to borrow books. His grandparents encouraged him, though neither of them had much education, and they bought him a set of encyclopedias. "I loved those books," he remembered. "I used to come downstairs before breakfast and read short articles. I enjoyed reading about famous men, and then I would pretend to be one of them. I guess it was partly a childish game and partly an escape. It wasn't too much fun to be a Negro when I was a kid." While studying for his bachelor's degree at Morehouse College, Reg worked on several political campaigns helping candidates get elected to government offices. At the same time he maintained a "B" average while majoring in political science.

With just two more years to complete at Harvard Law School, which also gave him a scholarship, Reg made a good start on his professional career. He said, "The good life for me is the kind of life where I can find satisfaction in public service." Then in 1975 he was the Massachusetts state commissioner of public utilities and from 1993 to 2009 he was judge of the United States District Court for the District of Massachusetts.

    Born in the 1950s, shopping malls were once the symbol of the U.S. consumer culture, but many are now dying out.

    Dying shopping malls can be found across the United States, often in middle-class suburbs. Economic decline in certain areas together with an upward trend towards online shopping and new forms of urban shopping centers have pushed the once seemingly unbeatable shopping malls into decline. It is estimated that 15 to 50 percent of shopping malls may close in the coming decades.

    American shopping culture follows its housing culture. Numerous shopping malls were therefore born after the Second World War, as Americans with cars and fat wallets moved to the suburbs. U.S. shopping malls were built at a rapid pace as shoppers fled cities, peaking in the mid-1990s when they were being built at a rate of 140 a year. Thus, too many shopping malls are left though construction has gradually decreased since then.

    Currently, there are around 1,500 shopping malls across the U.S. Most share a handful of similar feature. They usually contain two or three stories of stores separated by walkways. Food courts serve pizza and other fast food. Parking lots are big enough to easily misplace a car.

    Shopping malls in Europe might contain grocery stores or childcare centers, while those in Japan are often built around mass transit (交通枢纽). But the suburban American shopping malls are hard to get to and mainly sell clothes and gifts.

    As many shopping malls became redundant (过剩的), leaders in many U.S. towns who once fought for malls now struggle with how to transform them to new uses. Highland Mall in Texas is being transformed into a community college campus, and Lakeland Mall in Florida now houses a megachurch (大型教会). Others have been redeveloped to include housing, offices and even green space. However, it is hard to imagine every shopping mall meeting the demands for such transformations.
