Star Quality
A new anti-cheating system for counting the judges' scores in ice skating is flawed, according to leading sports specialists. Ice skating's governing body announced the new rules last week after concerns that a judge at the Winter Olympics may have been unfairly influenced.
Initially the judges in the pairs figure-skating event at the Winter Olympics in Salt Lake City voted 5 to 4 to give the gold medal to a Russian pair, even. though they had a fall during their routine. But the International Skating Union suspended the French judge for failing to reveal that she had been put under pressure to vote for the Russians. The International Olympics Committee then decided to give a second gold to the Canadian runners-up (亚军).
The ISU, skating's governing body, now says it intends to change the rules. In future 14 judges will judge each event, but only 7 of their scores--selected at random—will count.
The ISU won't finally approve the new system until it meets in June but already UK Sport, the British Government's sports body, has expressed reservations. "1 remain to be convinced that the random selection system would offer the guarantees that everyone concerned with ethical sport is looking for", says Jerry Bingham, UK Sport's head of ethics (伦理),
A random system can still be manipulated, says Mark Dixon, a specialist on sports statistics from the Royal Statistical Society in London. "The score of one or two judges who have been nobbled (受到贿赂) may still be in the seven selected."
Many other sports that have judges, including diving, gymnastics, and synchronized swimming, have a system that discards the highest and lowest scores. If a judge was under pressure to favors a particular team, they would tend to give it very high scores and mark down the opposition team, so their scores wouldn't count. It works for diving, says Jeff Cook, a member of the international government body's technical committee. "If you remove those at the top and bosom you're left with those in the middle, so you're getting a reasonable average."
Since the 2000 Olympics in Sydney, diving has tightened up in its- system still further. Two separate panels of judges score different rounds of diving during top competitions. Neither panel knows the scores given by the other. "We have done this to head off any suggestion of bias," says Cook.
Bingham urged the ISU to consider other options. "This should involve examining
the way in which other sports deal with the problem of adjudicating (裁定) on matter of style. and presentation," he says.

Can Mobile Phones Cause Disease？
1 "Mobile phone killed my man。"screamed one headline last year.Also came claims that an unpublished study had found that mobile phones cause memory loss.And a British newspaper devoid its front page to a picture supposedly(假定地)showing how mobile phones heat the brain.
2 For anyone who uses a mobile phone,these are worrying times.But speak to the scientists whose work is the focus of these scares and you will hear a different story.According to them,there is no evidence that mobile phones cause cancer or any other illness in people.
3 What we do have,however, are some results suggesting that mobile phones' emissions have a variety of strange effects on living tissue that can't be explained by the general radiation biology.And it's only when the questions raised by these experiments are answered that we' be able to say for sure what mobile phones might be doing to the head.
4 0ne of the odd effects comes from the now famous" memory loss" study.Alan Price and his colleagues at the University of Bristol placed a device that imitated the microwave emissions of mobile phones to the left ear of volunteers.The volunteers were just as good at recalling words and pictures they had been shown on a computer screen whether or not the device was switched on.Preece says he still can't comment Ol3 the effects of using a mobile phone' for years on end.But he rules out the suggestion that mobile phones have an immediate effect on our cognitive abilities."I'm pretty sure there is no effect on short-term memory," he says.
5 Another expert,Tatters all,remarked that his latest findings have removed fears about memory loss.One result,for instance,suggests that nerve cell synapses(突触)exposed to microwaves become more-rather than less-receptive(感受的)to undergoing changes linked to memory formation.
6 Hopefully, microwaves might turn out to be good for you.It sounds crazy, but a couple of years ago a team led by William Aden at the Veterans Affairs Medical Center in California,found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
