13、“ he said. “Back in the 1980s when we were trying to organize huge demos it was all about going to meetings and sending mail to regional people. I was a volunteer before the 1983 demonstration which attracted 400,000 marchers. The office was just awash with people printing things on old duplicators.

14、 People today feel more like they are part of a big movement. In the 1980s, we would read about demos all over the world a few days later in the newspapers.

In the past, some produce firms, including many in the tomato industry, use vo

26、luntary traceability programs but their approaches vary.Lawmakers said a mandatory program was overdue, and would help U.S. regulators improve safety and restore consumer confidence in food following a series of foodborne outbreaks since 2006.“It is the system that is broken,“ said Rep.

27、, chair of the House Appropriations subcommittee on agriculture. “You still do not have mandatory traceability, mandatory performance standards.

28、ned more than 1,400 people and put 286 in the hospital. They initially focused on tomatoes before shifting their attention to peppers.

29、 fresh fruits and vegetables and a national system to track produce.The Bioterrorism Act of 2002 requires produce processors and distributors to keep track of where food goes and where it came from. This does not include restaurants and farms. “We are going clown a road of examining what is going to

30、 work,“ said David Acheson, the Food and Drug Administrations associate commissioner for food protection. He told the subcommittee a mandatory program “would have an impact.“ Acheson said FDA does not believe it has explicit authority to mandate a tracking system.The Salmonella outbreak was the late

31、st health scare since 2006. The incidents, involving lettuce, peanut butter, pot pies and spinach, have resulted in dozens of hearings and proposals seeking tougher U.S. safety standards. The latest proposal, which DeLauro plans to introduce next week, would create a separate safety agency within th

32、e Department of Health and Human Services to handle all food safety issues currently administered by FDA In a briefing on food issues, the Grocery Manufacturers Association, which includes leading companies such as General Mills Inc and ConAgra Foods Inc, expressed doubt that food safety legislation

33、 would be passed this year.Prospects dim further next year with a new administration pursuing its own agenda and congress dealing with other issues including health care and transportation. “This may be our only window for some period of time to actually enact these important reforms,“ said Scott Fa

Many may point to the jealousy that plagues many rational people when a significant other Ubefriends/U someone of the opposite sex. Boil it down to the inherent differences between the sexes. It

40、just cant be done. Is it right?Wrong, say relationship experts. “The belief that men and women cant be friends comes from another era in which women were at home and men were in the workplace, and the only way they could get together was for romance,“ explains Linda Sapadin, Ph. D, a psychologist in

41、 private practice in Valley Stream, New York. “Now they work together and have sports interests together and socialize together.“ This cultural shift is encouraging psychologists, sociologists and communications experts to put forth a new message: though it may be tricky, men and women can successfu

42、lly become close friends. Whats more, there are good reasons for them to do so.Society has long singled out romance as the prototypical male-female relationship because it spawns babies and keeps the life cycle going; cross-sex friendship, as researchers call it, has been either ignored or trivializ

43、ed. We have rules for how to act in romantic relationships (flirt, date, get married, have kids) and even same-sex friendships (boys relate by doing activities together, girls by talking and sharing). But there are so few platonic male-female friendships on display in our culture that were at a loss

44、 even to define these relationships.A certain 1989 film starring Meg Ryan and Billy Crystal convinced a nation of moviegoers that romance always comes between men and women, making true friendship impossible. “When Harry Met Sally set the potential for male-female friendship back about 25 years,“ sa

45、ys Michael Monsour, Ph. D., assistant professor of communications at the University of Colorado at Denver and author of Women and Men as Friends: Relationships across the Life Span in the 21st Century. “Almost every time you see a male-female friendship, it winds up turning into romance.“In 1989, Do

46、n OMeara, Ph. D., a sociology professor at the University of Cincinnati-Raymond Walters College, published a landmark study in the journal Sex Roles on the top impediments to cross-sex friendship. Among several challenges he pointed out in his research, society may not be entirely ready for friendsh

47、ips between men and women that have no sexual subtext. People with close friends of the opposite sex are often barraged with nudging, winking and skepticism: “Are you really just friends?“ This is especially true, says OMeara, of older adults, who grew up when men and women were off-limits to each o
