SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.

BEIJING, Nov. 1 (Xinhua) -- The ministers of Brazil, South Africa, India and China (BASIC) in a Tuesday joint statement urged developed nations to fulfill their commitments and provide funds and technology to help developing nations tackle climate change.Developed nations should honor their commitments, made at the Copenhagen climate change conference in 2009, to provide 100 billion U.S. dollars annually by 2020 and ensure that there will be no funding gaps from 2013 to 2020, according to the statement.Developed nations should also fulfill their pledge to offer 30 billion U.S. dollars in "fast-start funding" to developing nations in order to help them address climate change, the statement said.The ministers agreed that the coming Durban climate change conference should achieve a "comprehensive, fair and balanced outcome" under the principle of common but differentiated responsibility.They called on the conference to clearly establish the second commitment period under the Kyoto Protocol, during which developed country parties to the Kyoto Protocol should undertake quantified emission reduction commitments.The Kyoto Protocol is the cornerstone of climate change and its second commitment period is an essential priority for the success of the Durban conference, according to the statement.H The joint statement was issued following a two-day meeting of ministers from the four nations, also known as the ninth BASIC Ministerial Meeting on Climate Change, a mechanism through which the four countries and other developing countries coordinate their efforts in climate change.Representatives of Group 77 countries, island countries and the Arab League also attended the meeting.The Durban conference is scheduled for November. The focus of the conference is expected to be the extension of the Kyoto Protocol and acquiring a commitment from developed countries for the protocol's next period.The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas emissions from 2008 to 2012.

UNITED NATIONS, Oct. 17 (Xinhua) -- China on Monday underlined the importance of safeguarding the peaceful use of outer space and preventing the weaponization of and an arms race in outer space, saying that "the outer space is the common wealth of mankind as the global public space."The statement came as Wang Qun, the Chinese ambassador for disarmament affairs, was taking the floor at the thematic debate on outer space at the First Committee of the UN General Assembly. The First Committee is in charge of disarmament and international security."The outer space is the common wealth of mankind as the global public space," Wang said. "The permanent peace of outer space is correlated to all nations' security, development and prosperity.""Meanwhile, with the growing reliance of mankind on outer space, the risk of the weaponization of and an arms race in outer space are on rise, and the uncertainties concerning outer space security are accumulating as well," he said. "Safeguarding the peaceful use of outer space and preventing the weaponization of and an arms race in outer space are common interest and obligations of all countries."In responding to the growing challenge for security in outer space, the international community also witnessed common grounds on opposing to the weaponization of outer space and advertising the Prevention of an Arms Race in Outer Space, he said.The General Assembly, for consecutive years, adopted " Prevention of an Arms Race in Outer Space" resolution by overwhelming majority of votes, calling for negotiations on an international legally-binding instrument on the prevention of an arms race in outer space at the Conference on Disarmament in Geneva."The mankind has marched into the 6th decade of outer space exploitation, and the manned space flight has made a history of 50 years," Wang said."Recently, China has successfully launched the Tiangong-1 ( Heavenly Palace 1) as a target spacecraft for rendezvous and docking experiment, which opens a new era of China's manned space flight, and also reflects that China is committed itself to the honorable objective of promoting the peaceful exploration and utilization of the outer space, maintaining peace and bringing benefit to mankind."

BEIJING, Dec. 17 (Xinhua) -- Senior Communist Party of China (CPC) official Zhou Yongkang has called for efforts to promote a police campaign aimed at better addressing public complaints.Zhou, a member of the Standing Committee of the Political Bureau of the CPC Central Committee, made the remarks in a written instruction on the campaign launched by the Ministry of Public Security on Friday.During the six-month campaign, police will be sent to more households to settle disputes and complaints or help solve public problems. The public will also be invited to supervise the work of the police, according to the ministry.Zhou said he believed the campaign would cement ties between the police and the masses and called on police to build a positive image for themselves during the initiative.The desirable "positive image" would only be possible by promptly addressing those most-attended security issues, said Meng Jianzhu, minister of public security, at Friday's launching ceremony.Meng urged his fellow police officers to make solid progress in enhancing the public's sense of security through this campaign.Police services on household registration, exit & entry, traffic and fire fighting were specifically mentioned by Meng, which were instructed to be strengthened or improved.

WASHINGTON, Nov. 25 (Xinhua) -- In the United States, the AIDS epidemic has plateaued, but it is still at "unacceptable high" level, a U.S. expert said ahead of the World AIDS Day."The situation is stable in the United States, stable in an unacceptable high level for at least 10 years and has not gone down. It's still a serious problem," Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), told Xinhua in an exclusive interview.According to Fauci, there are about 1.1 million people infected with HIV in the U.S., of which about 20 percent do not know they are infected. Those are the ones that more likely will infect other people. Since the world's first AIDS case was reported 30 years ago, the U.S. has seen close to 600,000 AIDS-related death. And among the 65,000 new infections each year in the U.S, about 50 percent are African Americans. In the United States, about 12 percent of the population is African American."Our new approach to prevention is to try and get access at community level, to people at most risk, to seek out to voluntarily test, to link them to care, and to automatically get them treatment," said Fauci. "When you get someone on treatment, it is extremely unlikely that they will infect their sexual partner."Fauci thought the international community's battle against the HIV/AIDS has gotten better over the last 30 years.Early on, when the disease was inaccurately thought to be a disease of developed world. There was a denial in many countries in Asia, in Southern Africa, South America and Caribbean, that this will turn out to be an extraordinary problem in those countries. As the years went by, it was clear that it was not a disease of gay men in the United States and the developed world. It was a disease mostly in the developing world when 90 percent of new infections occur in low- and middle-income countries and 67 percent of the cases are in Southern Africa."The response of the global community first was denial and not full appreciation of the potential impact of the pandemic. As the years have gone by, the response has been better and better," said Fauci, an immunologist that has made substantial contributions to research in the areas of AIDS and other immunodeficiencies, both as a scientist and as the head of NIAID.The advance in the arena of therapy with drugs has been " spectacular" and "very impressive", he said.In the early 1980 before there were any drugs, the median survival period of people in the United States who was infected with HIV, was about six to eight months. "Today in 2010, if someone was newly infected with HIV and he's 20-25 years old, and you put them on therapy, you can predict mathematically that they will live additional 50 years," said Fauci.Over the last couple of years, there has been "significant but slow" advances with vaccines against HIV. For example, there was a trial that was conducted in Thailand in which there was a modest degree of efficacy, about 31 percent of protection."That's not enough to have a vaccine available for widespread use but give us some important clues into what next generation of vaccines would be," said Fauci.As to the "three zeros" target adopted by the United Nations this year, Fauci said that it's "aspirational but not gonna be easy.""It is good to set very high goals for the future. I don't think that we realistically are gonna get to zero new infections, zero new discrimination, zero (AIDS-related) death in the next few years," said Fauci. "I think it will take several years to get there. I believe that if more countries and the international community are engaged to play a role in trying to stop HIV, to prevent and treat and care for HIV-infected individuals, that we will automatically achieve that objective."
