BEIJING, May 10 (Xinhuanet) -- Professional social networking site LinkedIn is aiming for a valuation of 3.3 billion U.S. dollars for its initial public offering, media reports said Tuesday.The Mountain View, California-based company is expected to begin trading on the New York Stock Exchange within the next month and will use the symbol "LNKD."It plans to offer 7.84 million shares priced at 32 dollars to 35 dollars each, according to the filing, which it submitted to the Securities and Exchange Commission.LinkedIn, which has more than 100 million members in over 200 countries and territories, is seeking to raise as much as 274.4 million dollars from the initial public offering (IPO) with 146.6 million dollars going to the company itself.In 2010, LinkedIn made 15 million dollars in profit on 243 million dollars in revenue, according to the filing.LinkedIn's biggest shareholder is its founder and chairman, Reid Hoffman, who owns more than 21 percent of the company.

BEIJING, Feb. 15 (Xinhua) -- A senior Chinese mainland official has said the government will work with Taiwan to enhance cross-Strait economic exchanges and cooperation.The mainland would this year focus on fulfilling the cross-Strait Economic Cooperation Framework Agreement (ECFA) and conducting follow-up negotiations on the pact, which took effect in September last year, Xu Mang, director of the economy bureau of the Taiwan Affairs Office of the State Council, told Xinhua in an interview.Top of the follow-up agenda was cross-Strait investment protection. The mainland hoped to reach a mutually beneficial agreement on the issue with Taiwan at an early date, with concerns of both sides respected, Xu said.Xu said the two sides should adhere to the principle of balance in negotiations, aiming for effective protection, fewer restrictions and more convenience for cross-Strait investment.Mainland and Taiwan negotiators agreed in December last year to continue discussing the investment protection agreement at the seventh round of talks scheduled for this year.The mainland would also continue this year to encourage investment in Taiwan, address Taiwan enterprises' concerns over economic transformation and development, and promote cross-Strait cooperation in finance, modern services and agriculture, Xu said.The first step in implementing the ECFA, the "early harvest program," took effect on Jan. 1, when the mainland reduced tariffs on 539 Taiwanese items, or 16 percent of imports from Taiwan, while Taiwan cut duties on 267 mainland items, 10 percent of imports from the mainland.Within two years, the duties on those products will be reduced to zero.Xu said the implementation of the early harvest program would boost trade links across the Strait.As the products receiving tariff reductions covered industries including agriculture, petrochemicals, machinery, textiles and transport, Taiwan businesses on the mainland would benefit from lower purchase costs on Taiwan raw materials, Xu said.Taiwan's small and medium-sized enterprises and low-income groups would especially benefit from the tariff reductions on exports of 18 agricultural products to the mainland, Xu said.Statistics from Taiwan showed that driven by the tariff reduction, the island's small and medium-sized enterprise export trade volume to the mainland would increase to 18 billion U.S. dollars per year."The tariff reduction policy will benefit more Taiwan compatriots," Xu said.Cross-Strait trade volume totaled 145.37 billion U.S. dollars last year, a rise of 36.9 percent year on year. The figure included 115.69 billion U.S. dollars of Taiwan exports to the mainland, up 20.2 percent. 

BEIJING, Feb. 12 (Xinhua) -- China's recent revocation of a national scientific award due to academic fraud has been welcomed by the public, but experts warn the country still has a long way to go to bring an end to such dubious academic practices.On Feb. 1, China's Ministry of Science and Technology, revoked the State Scientific and Technological Progress Award (SSTPA) given to Li Liansheng, former professor of Xi'an Jiaotong University in 2005.An investigation found Li had plagiarized others' works and fabricated data in his winning project, a research on key technologies for designing and manufacturing scroll compressors. Li was investigated after the science ministry received tip-offs from six professors (including four retired) in his university.The ministry subsequently canceled his prize and retrieved the money awarded.Zhao Baojing, a senior official with the National Office for S&T Award, told Xinhua it was the first time China had withdrawn a national scientific honor.The revocation soon sparked pubic discussion over academic integrity. Tan Gang, a citizen in Shenzhen, wrote on his microblog, "Though the revocation came a bit late, it is progress. It's a warning against academic misconduct."Shi Ying, vice director of Shanxi Academy of Social Sciences, said, the move demonstrated China's "zero-tolerance" for academic fraud, and would help clean up the academic field."However, academic fraud is still rampant, which not only damages academic integrity, but also harms the innovative capacity of China in a broader sense," said Shi.Anti-fraud activist Fang Zhouzi, who runs a website on anti-academic fraud from his Beijing home, said "This is by far the harshest stance China has ever taken against academic fraud, which should be viewed as progress." He so noted China still has a long way to go in the fight against academic fraud.Fang said, the science ministry's move does not mean China is really cracking down on academic fraud. The plagiarist might have not been found out if it were not for years of unyielding efforts made by the six professors.The scandal again highlights that academic fraud is alive and well in China. A survey conducted among 30,078 respondents in 2009 by the China Association for Science and Technology (CAST) showed that nearly half of the science-related workers in China's research institutes, universities, medical institutes and hospitals think academic cheating is "common."Fang attributed the prevalence of academic fraud in China to lax punishments and loopholes in the academic evaluation system.Zero tolerance of academic fraudChina's science minister, Wan Gang, said on several occasions "We hold zero tolerance for academic fraud."However, Fang said "zero tolerance" was a slogan rather than the actual case. Many cases of academic fraud, even publicly exposed, were "tolerated" eventually. "Lax punishment makes academic fraud less costly."

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.

BEIJING, Feb. 8 (Xinhua) -- China plans to sell 600 billion yuan (91 billion U.S. dollars) worth of welfare lotteries from 2011 to 2015, up 73.6 percent from the past five years, an official from the Welfare Lottery Distribution and Management Center (WLDMC) has said.The sales of welfare lotteries posted an annual increase of 18.7 percent over the past five years, from 41.2 billion yuan in 2006 to 96.8 billion in 2010, the official said.The sales totalled 345.53 billion yuan from 2006 to 2010.The center believed that there would be broad prospect for welfare lottery sales with the increase of people's income and the development of philanthropy.According to China's Regulations on Lottery Management, money raised through lotteries is divided into three parts: the jackpot, lottery management fees, and lottery public funds.The government-run lottery raised a total of 30 billion yuan for public welfare funds in 2010, according to the WLDMC statistics.The WLDMC is administered by the Ministry of Civil Affairs, which was authorized by the State Council, or China's Cabinet, to raise welfare funds through lottery sales in 1987.
