BEIJING, Aug. 1 (Xinhua) -- The after-tax CIF (cost, insurance and freight) price of China's jet fuel imports has been set at 7,768 yuan (1,206 U.S. dollars) per metric ton for August, China's economic planner said on Monday.The price adjustment marked the first time for the economic planner to adjust jet fuel prices on a monthly basis after it announced jet fuel pricing reforms in July, according to a notice posted on the National Development and Reform Commission (NDRC)'s website.The NDRC announced on July 7 that it would introduce a market-oriented jet fuel pricing mechanism starting from Aug. 1.Under the new mechanism, the ex-plant price of jet fuel is required to be no higher than the after-tax CIF price of jet fuel imports from Singapore, Asia's largest oil trading and storage center.Taking transportation expenses, trade volumes and international crude oil prices into account, the jet fuel premium is negotiable between jet fuel sellers and buyers and will be reviewed once a year, while jet fuel ex-plant prices will be adjusted on the first day of every month, according to the NDRC.

Beijing, Sept. 13 (Xinhuanet) -- A fear of taking antidepressants often results in people's reluctance of going to see the doctor when they are suffering from depression, a study find.The finding was published Monday in the U.S. journal Annals of Family Medicine.The researchers from the University of California investigated 1,054 adults on why they wouldn't tell the doctors about their depression symptoms, as well as any possible mental disorder.Among the participants, 43 percent admitted that they had been reluctant to tell the doctor about their depression symptoms.Their top concern was the possibility of being prescribed an antidepressant -- a worry voiced by 23 percent of the whole study group.Another 16 percent thought dealing with "emotional issues" is not the doctor's job. And a similar percentage worried that the diagnosis of depression may leave a negative record on their medical records.The study would be helpful for looking into the reasons that patients harbor the attitudes that they do, said Dr. Hellerstein of the New York State Psychiatric Institute and Columbia University Medical Center in New York.

LOS ANGELES, July 3 (Xinhua) -- Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, increasing the sea level more than already projected, a new study suggests.The subsurface ocean layers surrounding the polar ice sheets will warm substantially as global warming progresses, according to the study led by researchers from the University of Arizona (UA).In addition to being exposed to warming air, underwater portions of the polar ice sheets and glaciers will be bathed in warming seawater, said the study appearing on the website of the American Association for the Advancement of Science (AAAS) on Sunday.The research, based on 19 state-of-the-art climate models, proposes a new mechanism by which global warming will accelerate the melting of the great ice sheets during this century and the next."To my knowledge, this study is the first to quantify and compare future ocean warming around the Greenland and the Antarctic ice sheets using an ensemble of models," said lead author Jianjun Yin, a UA assistant professor of geosciences.According to the study, the subsurface ocean along the Greenland coast could increase as much as 3.6 F (2 C) by 2100.Most previous research has focused on how increases in atmospheric temperatures would affect the ice sheets, he said."Ocean warming is very important compared to atmospheric warming because water has a much larger heat capacity than air," Yin said. "If you put an ice cube in a warm room, it will melt in several hours. But if you put an ice cube in a cup of warm water, it will disappear in just minutes."Given a mid-level increase in greenhouse gases, the researchers found the ocean layer about 650 to 1,650 feet (200 to 500 meters) below the surface would warm, on average, about 1.8 F (1 C) by 2100. Along the Greenland coast, that layer would warm twice as much, but along Antarctica would warm less, only 0.9 F (0.5 C)."No one has noticed this discrepancy before -- that the subsurface oceans surrounding Greenland and Antarctica warm very differently," Yin said.Part of the warming in the North comes from the Gulf Stream carrying warm subtropical waters north. By contrast, the Antarctic Circumpolar Current blocks some of the subtropical warmth from entering the Antarctic's coastal waters.Even so, the Antarctic ice sheet will be bathed in warming waters, according to the study.This paper adds to the evidence that sea level would rise by the end of this century by around one meter and a good deal more in succeeding centuries, the study noted.The study, "Different Magnitudes of Projected Subsurface Ocean Warming Around Greenland and Antarctica," is scheduled for the upcoming edition of Nature Geoscience later this month.

SYDNEY, Aug. 25 (Xinhua) -- An Australian national survey has shown most respondents have been unsatisfied with their employers and managers on supporting employees with mental illness in the workplace, the charity Sane Australia said on Thursday.The survey, Australia's Working life and mental illness, by the national mental health charity Sane Australia, found that 95 percent of the 520 respondents thought employers and managers needed education on mental illness and how to manage its effects in the workplace.While more than 60 percent said their mental illness had not been a barrier when finding a job, the majority said that they haven't got any support from their employers or mangers once they were at work."The survey paints a concerning and unsatisfactory picture of Australian workplaces," SANE Australia's Executive Director Barbara Hocking said in a statement on Thursday."Many employees, including those who care for a family member with a mental illness, are being disadvantaged by a lack of flexibility, such as being able to work part-time, to work from home at times or to have adjustments made in the workplace," she said.According to the survey, two thirds of people reported to have revealed their histories of mental illness to their employer or manager.
