WASHINGTON, Nov. 14 (Xinhua) -- Nearly a fifth of all Americans 12 years or older have hearing loss so severe that it may make communication difficult, according to a new study led by Johns Hopkins University researchers and published Monday in the Archives of Internal Medicine.The findings, thought to be the first nationally representative estimate of hearing loss, suggest that many more people than previously thought are affected by this condition.Study leader Frank Lin, an assistant professor, and his colleagues used data from the National Health and Nutritional Examination Surveys (NHANES), a research program that has periodically gathered health data from thousands of Americans since 1971. The researchers analyzed data from all participants age 12 and over whose hearing was tested during NHANES examinations from 2001 to 2008. Unlike previous estimates, NHANES includes men and women of all races and ages, from cities scattered across the country, so it's thought to statistically mimic the population of the Untied States.Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumps to about 48 million, or 20.3 percent, for people who have hearing loss in at least one ear. These numbers far surpass previous estimates of 21 to 29 million.Hearing loss prevalence nearly doubled with every age decade, with women and blacks being significantly less likely to have hearing loss at any age. Lin and his colleagues aren't sure why these groups appear to be protected. However, he notes that the female hormone estrogen, as well as the melanin pigment in darker skin, could have a protective effect on the inner ear.

BEIJING, Dec. 16 (Xinhua) -- China issued rules for pilot programs of RMB Qualified Foreign Institutional Investors (RQFII) on Friday, formally giving a green light to investment of overseas RMB funds in mainland securities markets.The move is expected to widen the investment channel of overseas RMB funds and add new momentum to the country's bid to make the RMB an international currency.Hong Kong subsidiaries of fund management companies and securities firms can use RMB funds raised in Hong Kong to invest in mainland securities within a permitted quota, according to the rules jointly released by the China Securities Regulatory Commission (CSRC), the People's Bank of China and the State Administration of Foreign Exchange.The total investment quota of RQFII pilot programs is set at around 20 billion yuan (3.15 billion U.S. dollars), according to the rules.To control risks, qualified investors should invest no less than 80 percent of the RMB funds they raised in fixed-income securities, while investment in stocks and equity funds should account for no more than 20 percent.The CSRC will join other related departments to study the possibility of further expanding the trial program after its launch, said a CSRC official who declined to be identified.The launch of the RQFII will open another significant channel for overseas RMB funds to flow back into the country, said the CSRC official.It will also help diversify investment products for overseas RMB funds and facilitate off-shore RMB business, the official said.The RMB is not fully convertible under the capital account but China has stepped up efforts to make the currency more international over the past few years.The government has encouraged the use of the RMB in cross-border trade and investment settlement and approved foreign direct investment in overseas RMB funds obtained overseas.It also allowed Hong Kong to establish an offshore yuan market and has expanded trade settlement agreements and currency swaps to create more channels for the yuan to circulate outside the mainland.

BEIJING, Oct. 10 (Xinhua) -- The State Council, or China's cabinet, announced on Monday it will tax all resource products starting Nov. 1, extending the resource tax on domestic sales of crude oil and natural gas from some regions to the entire country.The list of taxable resources widened from crude oil and natural gas to coal, rare earth, salt and metal from Nov. 1, according to the country's revised resource tax regulations.The expansion of the resource tax is part of China's efforts to encourage energy conservancy and limit environmental damage.Sales of crude oil and natural gas nationwide will be taxed at a rate between five and 10 percent of their sales value, according to the revised regulations.The regulations impose a sales tax ranging from eight (1.25 U.S. dollars) to 20 yuan per metric ton on coking coal and from 0.40 to 60 yuan per metric ton on rare earth ore.Taxes on other types of coal stood unchanged at 0.30 to five yuan per metric ton.The tax rate for other non-ferrous metals is set between 0.4 to 30 yuan per metric ton. Ferrous metals will be taxed at two to 30 yuan per metric ton.Taxes on precious non-metallic ore will be between 0.5 to 20 yuan per kg or per carat, while taxes on cheap non-metallic ore are set between 0.5to 20 yuan per metric or per cubic meter.China's current resource tax is levied based on production volume instead of sales value, thus preventing the government from benefiting from energy and commodity price increases.Nonetheless, energy giants and mining companies such as PetroChina and Sinopec have enjoyed large profit margins on the sale of resources under the current tax scheme.A resource tax on oil and natural gas was introduced at a rate of five percent in northwest China's Xinjiang Uygur Autonomous Region on June 1, 2010 before being extended to 11 other provinces in December last year.
