WASHINGTON, Aug. 16 (Xinhua) -- The White House announced Tuesday that the U.S. Departments of Agriculture, Energy and Navy will invest up to 510 million U.S. dollars in partnership with the private sector to facilitate the country's biofuel industry development."Biofuels are an important part of reducing America's dependence on foreign oil and creating jobs here at home," U.S. President Barack Obama said in a White House statement.The initiative is a response to a directive from Obama issued in March as part of the Blueprint for A Secure Energy Future, the administration's framework for reducing dependence on foreign oil."But supporting biofuels cannot be the role of government alone. That's why we're partnering with the private sector to speed development of next-generation biofuels that will help us continue to take steps towards energy independence and strengthen communities across our country," Obama added.The joint plan calls for the three departments to invest up to 510 million dollars in the next three years, which will require substantial cost share from private industry, in a bid to reduce U. S. reliance on foreign oil and create jobs at home."By building a national biofuels industry, we are creating construction jobs, refinery jobs and economic opportunity in rural communities throughout the country," said U.S. Agriculture Secretary Tom Vilsack.White House figures revealed that the world's largest economy spends more than 300 billion dollars on imported crude oil every year.With a slackening economic recovery and the government's approval rate at a record low level, the Obama administration is rolling out a string of measures in recent days to accelerate economic growth and job creation.

CANBERRA, Aug. 3 (Xinhua) -- As many as a quarter of Australian women have experienced some form of assault or sexual abuse, and the higher proportion of the abuse, the higher rates of metal illness a woman tends to suffer from, a new study released on Wednesday found.Researchers from the University of Melbourne and the University of New South Wales conducted the study survey of 4451 Australian women aged 16 to 85. It looked at their experience of the four most common types of gender-based violence - sexual assault, rape, stalking and being badly beaten by their partners.About 15 percent of Australian women report sexual assault, while eight percent report rape, 10 percent said they have a stalker and eight percent report being beaten by their partner.It found strong links between those four types of violence and mental health problems including attempted suicide, posttraumatic stress disorder, panic attacks, depression, anxiety, and substance abuse.Among the women who experienced at least one form of violence, 30 percent had a mood disorder, nearly 40 percent an anxiety disorder, 23 percent were abusing substances and 15 percent were affected by posttraumatic stress syndrome.For the women who suffered higher levels of violence, the rates of anxiety disorders was 77 percent, 52 percent for mood disorders, substance abuse 47 percent and posttraumatic stress syndrome 56 percent.More than six percent of women experienced one form of violent had attempted suicide, compared to 35 percent of women who suffered at least three forms of violence.Public health expert Dr Susan Rees from the University of New South Wales' school of psychiatry, who led the research, said she is especially concerned about the suicide rate of women who are abused."What we found was that there's a high association or a strong association between exposure to gender-based violence and all the three broad classes of mental disorder - so that includes mood, anxiety, substance abuse - and a very high association with attempted suicide," she said in the report released on Wednesday."Women who've not experienced gender-based violence have about a 1.6 percent rate of attempted suicide and that increased to six percent of women who had experienced one type of gender-based violence."She said that gender-based violence was also associated with physical disability, impaired quality of life and a worsening of any existing mental disorders.Dr Rees called for the health care system, particularly psychiatric services, to work closer with women's services to improve support for victims of violence.She added that the federal government also need to underscore the importance of getting to the root cause of the violence against women by looking at attitudes towards women and gender inequality.The study was published in the Journal of the American Medical Association.

  

WASHINGTON, June 2 (Xinhua) -- When humans see red, their reactions become both faster and more forceful, according to a new study published this week in the U.S. bimonthly journal Emotion.The findings may have applications for sporting and other activities in which a brief burst of strength and speed is needed, such as weightlifting. But the authors caution that the color energy boost is likely short-lived.The study measured the reactions of students in two experiments. In the first, 30 fourth-through-10th graders pinched and held open a metal clasp. Right before doing so, they read aloud their participant number written in either red or gray crayon. In the second experiment, 46 undergraduates squeezed a handgrip with their dominant hand as hard as possible when they read the word "squeeze" on a computer monitor. The word appeared on a red, blue, or gray background.In both scenarios, red significantly increased the force exerted, with participants in the red condition squeezing with greater maximum force than those in the gray or blue conditions. In the handgrip experiment, not only the amount of force, but also the immediacy of the reaction increased when red was present.The colors in the study were precisely equated in hue, brightness, and chroma (intensity) to insure that reactions were not attributable to these other qualities of color."Red enhances our physical reactions because it is seen as a danger cue," explains coauthor Andrew Elliot, professor of psychology at the University of Rochester and a lead researcher in the field of color psychology. "Humans flush when they are angry or preparing for attack," he explains. "People are acutely aware of such reddening in others and it's implications."But threat is a double-edged sword, argue Elliot and coauthor Henk Aarts, professor of psychology at Utrecht University, in the Netherlands. Along with mobilizing extra energy, "threat also evokes worry, task distraction, and self-preoccupation, all of which have been shown to tax mental resources," they write in the paper.In earlier color research, exposure to red has proven counterproductive for skilled motor and mental tasks: athletes competing against an opponent wearing red are more likely to lose and students exposed to red before a test perform worse.
