BEIJING, Oct. 3 (Xinhuanet) -- Ziqian (not his real name, but an avatar he uses online) is in Paris working on his master's degree, but he stays in close touch with his contacts in China through Sina Corp's Weibo, a micro blog platform. It was a pleasant way to keep up with acquaintances. But that all changed when Ziqian quoted a blog post from an alumnus of his alma mater, Nanjing University, on July 5. It said the school did not organize students to sing Red songs ahead of July 1, the 90th anniversary of the founding of the Communist Party of China. Ziqian suddenly found himself inundated with comments from enraged bloggers whom he didn't know. He had lost all integrity, they said.Ziqian spent the whole night arguing with one netizen who assailed him with insults. He was left feeling tired and puzzled.He said he would have given up micro-blogging altogether as "purely useless", but he uses it to stay in touch with his girlfriend.Micro-blogging has been growing rapidly, dwarfing the many other forms of social networking that came into being only three or four years ago.Famed for spreading messages almost instantly and supervising the doings of agencies and organizations, micro blogs have already won some notable battles.In March, micro-bloggers persuaded the city of Nanjing, Jiangsu province, to spare 600 old trees that were to be cut down; they also organized assistance to earthquake victims in Japan.In July, they brought the Red Cross Society of China and other philanthropies under scrutiny.But, like everything in life, there is also a downside to micro-blogging.In the Weibo-dominated virtual world, Ziqian's experience has proved a common occurrence. A 28-year-old woman, surnamed Zhang, who declined to disclose her full name, works at a TV station in Jiangsu province. She recounted her recent encounter with online abusive remarks.After watching a popular talent show, Zhang wrote half-jokingly online - without using her real name - that the program was boring and lacked imagination. Regarding herself as an "industry insider", Zhang believed her reasoning had some objective basis.Nevertheless, she was soon confronted with a wave of criticism, some of it vulgar, saying she had no appreciation for the arts."I was very depressed by the comments. It's like you get kidnapped by mainstream opinion," she said. "I lost the desire to share my views with others.""I respect the freedom of speech doctrine, and everyone is allowed to publicize his or her thoughts," Zhang wrote in a separate post. "But don't hurl random assaults at others and take for granted that whatever you say is truth."Micro blogs have also made some ordinary people famous, though not in the way they would like.Zhang Mingyi, 22, is one such person.After appearing on a dating show on Shanghai-based Dragon TV, she said her micro blog inboxes were filled every day with letters lashing out at her, because of her open enthusiasm for Japanese culture and a failed marriage.Some netizens are relentless in their resentment of her. Even her micro blog followers received warnings to stay away from the "quisling". One such message read: "Go tell her to marry a Japanese man. Don't act so shamelessly in China".Similarly, Guo Meimei, now a household name, said she was being stalked and even threatened in early September, after she bragged in a micro blog post about her wealth and - untruthfully - claimed to hold a position at the Red Cross Society of China.Bloggers launched a vast campaign boycotting a song she released online and an online game she endorsed. They satirized her plastic surgeries and gossiped about her whereabouts. In a recent interview with China Daily, Guo said the animosity she stirred was so intense that she had even considered suicide."I feel like I am an enemy of the state," she said. "The truth is that I am just a stupid girl who did something really stupid. No matter what I do, nobody wants to forgive me."Celebrities are more likely to become the targets of the word-of-mouth maelstrom online. Yang Lan, for instance, a famous TV anchorwoman, came under tremendous pressure as bloggers dug into her connections with China-Africa Hope Project, an organization set up by a prominent philanthropist, Lu Junqing, that became controversial because he empowered his 24-year-old daughter to manage the charity's substantial donated funds.Bloggers questioned whether the purpose of Lu's initiative was charity or cashing in on donators. Rumors held sway on micro blogs.A recent study from University of Michigan suggests that it is crucial that people distinguish between the truth and unfounded rumors in online social media, where vast amounts of information are easily spread across a large network by sources of unverified authority.According to Xie Gengyun, author of the 2010 China Micro Blog Annual Report and deputy dean at the Arts and Humanities Research Institute at Shanghai Jiaotong University, micro blogs can generate and spread unfounded rumors, such as the "Shanxi earthquake" and "Louis Cha's death"."Micro-bloggers are currently the better-educated people in China. But users will soon include those at the grassroots level, and the function of micro blogs will change from celebrity-watching to online socializing and venting about life's disappointments," Xie said.China's Internet, with more registered users than any other nation, is a lively forum for public opinion, said Xinhua News Agency. But "concocting rumors is itself a social malady, and the spread of rumors across the Internet presents a massive social threat."The micro blog platform tends to breed more rumors and assaults than other channels because of the limited amount of characters each post can use, according to Xiong Yihan, a sociologist with Fudan University."The word limit has made it hard to present a balanced and fair opinion. Besides, posts with extreme views are more likely to be forwarded online, because they satisfy people's thirst for the unknown," Xiong said.Xiong said Internet companies should suspend the accounts of users who spread rumors or libelous statements.

BEIJING, Dec. 12 (Xinhuanet) -- For many multinational firms, the past 10 years in China have not only marked the rise of the world's second-largest economy but have also been a decade of expansion and profit growth.As they look back at this "golden decade", which is often used to describe the days after China entered the World Trade Organization (WTO) in 2001, their early expectations and ambitions in a more liberalized Chinese market were found to be more than fulfilled.When German auto giant BMW set foot on the Chinese mainland by establishing its first office in Beijing in 1994, its products were still far too luxurious for ordinary Chinese.In 2001, only 6,500 vehicles were sold under the BMW and Mini brands in China.NYK Diana, a container ship, anchors at Qingdao Port in East China's Shandong province on Thursday, as workers load cargo.But sales started to pick up with China's WTO entry, when the removal of trade barriers brought unprecedented economic growth and a booming market.In 2010, the vehicle maker, which started a joint venture with the domestic Brilliance China Automotive in 2003, sold 169,000 vehicles in China.That record is set to be broken this year as more than 170,000 cars were sold only in the first three quarters."We are both beneficiaries and firm supporters of the open market system," said Christoph Stark, president and CEO of BMW's Greater China region.By liberalizing its market, China, which celebrated the 10th anniversary of its WTO accession on Sunday, has become a thriving market and a savior for foreign enterprises hit hard by the global downturn.In 2009, when General Motors declared bankruptcy in the United States amid the global recession, its Chinese branch saw sales rise 66.9 percent year-on-year to more than 1.8 million units.In 2010, China overtook the United States to become GM's largest national market.The list of similar companies is extensive, as China's decade-long membership of the WTO has helped the Asian powerhouse attract 347,000 foreign firms with investment of more than 0 billion in the past 10 years.Chong Quan, deputy representative for China's international trade talks, said foreign enterprises made more than 0 billion in profit in the 10-year period, with an average annual increase of 30 percent."The accession to the WTO has made China a more transparent, safe and predictable market, as well as an essential part of the global economy," said Dominique Poulique, president of Alstom China.The French power engineering and train company, with more than 30 entities and about 10,000 employees in China, is one of the major foreign suppliers to the Chinese rail transport market."Rapid changes took place in China in the past decade, with its massive investment in infrastructure construction and notable development in energy," Poulique said.Wang Zhile, director of the research center of transnational cooperation under the Ministry of Commerce, said increasing shared interests between China and multinationals are putting them into an inseparable community, one that has found win-win solutions in the past decade.There is also high-quality labor at a relatively low cost, including white-collar workers, he added.Admittedly, the huge market and rich resources have powered up multinational firms in global competition, especially during and after the financial crisis.Forty-nine percent of the responding multinational companies had higher expectations for China in the wake of the global financial crisis in 2008 and 2009, according to a recent survey by the Economist Intelligence Unit, a business information arm of the Economist Group.Although showing signs of a slowdown, China's economy is still widely expected to grow by more than 8 percent next year, at a time when debt and financial instability are weakening growth in other leading economies.Poulique said he expected China's rapid growth to continue into the next decade, especially in the infrastructure construction market."For Alstom, the top task here is to keep adapting to the changing business environment," he said.Many foreign companies are moving research and development facilities to China in the hopes of making it a base for talent and technology.In Shanghai, 347 multinationals have set up regional headquarters, with the establishment of 333 foreign-funded research and development centers.

BEIJING, Oct. 20 (Xinhuanet) -- A Teenager's intelligence is not fixed as usually thought. Instead, it can go through swings in a few years, according to a British study reported online in Nature.Teenagers' IQ can rise or fall 20 points over time, researchers from Wellcome Trust Centre for Neuroimaging of Kings College, showed in their study.IQ (short for "intelligent quotient") is an gauge of mental capability measured through a series of standardized tests of language skill, spatial ability, arithmetic, memory and reasoning.To get the findings, Cathy Price, senior researcher of the study, and her colleagues tested 33 British teenagers between the ages of 12 to 16 in 2004, who had average IQ scores around 100. Then the teenagers were retested four years later.The researchers found the volunteers' IQ scores went up and down over the four years, with some teenager's scores rising by as many as 20 points, and others' dropping by the same points."That is quite astounding," cheered psychologist Robert Plomin from the same university but not involved in the study. Dr. Price and her colleagues don't know the causes of such fluctuations in the scores they tested, but speculate that learning experiences might account the changes, reported by the Wall Street Journal Today. "We have to be careful not to write off poorer performers at an early stage when in fact their IQ may improve significantly given a few more years," stated Dr. Price cited by the Huffington Post.

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage."The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there are two subsets of monocytes -- an inflammatory subset that defends against pathogens and a reparative subset that supports healing. But if the inflammatory response is excessive, it can block the healing process and exacerbate conditions such as heart disease and cancer."Cells damaged by injury or disease release a cocktail of chemicals called cytokines that attract immune cells to the site of the damage. Inflammatory monocytes are guided to sites of tissue injury by a receptor protein called CCR2, and the MGH-led team devised a strategy targeting that molecule to block the inflammatory process but not the action of the reparative monocytes.Small interfering RNA (siRNA) technology prevents production of specific proteins by binding to associated messenger RNA molecules and preventing their translation. However, the technique requires extreme precision in developing the right siRNA molecule and delivering it to the correct cellular location.To make sure that their siRNA preparation targeted the right monocytes, researchers first confirmed that its use reduced levels of CCR2 in monocytes and increased levels of the fragments produced when siRNA binds to its target. They then showed that monocytes from mice treated with the siRNA preparation were unable to migrate towards CCR2's usual molecular target. Experiments in animal models of several important diseases showed that the siRNA preparation reduced the amount of cardiac muscle damaged by a heart attack, reduced the size and the number of inflammatory cells in atherosclerotic plaques and in lymphomas, and improved the survival of transplanted pancreatic islets."These inflammatory monocytes are involved in almost every major disease," Nahrendorf explains. "Anti-inflammatory drugs currently on the market hit every inflammatory cell in the body, which can produce unwanted side effects. This new siRNA treatment doesn't affect inflammatory cells that don't rely on the CCR2 receptor. That makes a big difference."

HELSINKI, Nov.23 (Xinhua) -- Nokia Siemens Networks is planning to cut its workforce by 17,000 worldwide by the end of 2013, the company said in a statement on Wednesday in Espoo, Finland.The company said the measures are part of an extensive global restructuring program, in which it will focus on mobile broadband and services."We need to take the necessary steps to maintain long term competitiveness and improve profitability in a challenging telecommunications market," said the company's Chief Executive Rajeev Suri in the statement.Rajeev Suri called the job cuts regrettable but necessary, and said the company would provide support for individuals and communities affected by the cuts, but defended the decision on economic grounds.Nokia Siemens is aiming to cut operating expenditures by around a billion euros over two years.Some 74,000 people currently work for the Espoo-based company in 150 countries, around 7,000 in Finland. The company will announce the geographical distribution of the job cuts later on.
