单选题Shoppers who have flocked to online stores for their holiday shopping are losing privacy with every mouse click, according to a new report． The study by the Washington—based Electronic Privacy Information Center scrutinized privacy policies on 100 of the most popular online shopping sites and compared those policies with a set of basic privacy principles that have come to be known as"fair information practices"． The group found that none of the 100 sites met all of the basic criteria for privacy protection, which include giving notice of what information is collected and how it is used, offering consumers a choice over whether the information will be used in certain ways, allowing access to data that give consumers a chance to see and correct the information collected, and instituting the kind of security measures that ensure that information won't fallinto the wrong hands． "This study shows that somebody else, other than Santa, is reading your Christmas list, "said Jeff Chester,executive director of the Center for Media Education, which also worked on the survey． The online privacy of children is protected by Federal Trade Commission rules, but adults do not share the same degree of privacy protection．The movement, like the online shopping industry, favors self-regulation over imposition of further movement restrictions on electronic commerce． Marc Rosenberg, executive director of the privacy group, said the study shows that self regulations have failed, "We need legislation to enforce fair information practices, "he said, "Consumers are at greater risk than they were in 1997, "when the group released its first report． The survey also asked whether the 1 00 sites used"profile—based"adverising, and whether the sites incorporate"cookies"technology,which gives Websites basic information on visitors． Profiling is the practice of gathering in then used to create targeted advertising on Websites． All but 18 of the top shopping sites did display a privacy policy,a major improvement over the early days of electronic commerce, when such policies were scarce．But that did not satisfy the privacy group．"Companies are posting privacy policies, but these policies are not the same thing as fair information practices, "Rosenberg said． The sites also did not perform well by other measures, the group said it found that 35 of the sites feature profile-based advertising, and 87 percent use cookies．The group concluded that the phonies that were posted"are typically confusing, incomplete, and inconsistent"．The report, "Surfer Beware Ⅲ：Privacy Policies Without Privacy Protection, "is the third such survey by the group．It called for further development of technologies that help consumers protect their privacy and even anonymity when exploring the Internet．

单选题Placing a human being behind the wheel of an automobile often has the same curious effect as cutting certain fibers in the brain. The result in either case is more primitive behavior. Hostile feelings are apt to be expressed in an aggressive way. The same man who will step aside for a stranger at a doorway will, when behind the wheel, risk an accident trying to beat another motorist through an intersection. The importance of emotional factors in automobile accidents is gaining recognition. Doctors and other scientists have concluded that the highway death toll resembles a disease epidemic and should be investigated as such. Dr. Ross A. Mcfarland, Associate Professor of Industrial Hygiene at the Harvard University School of Public Health, said that accidents "now constitute a greater threat to the safety of large segments of the population than diseases do." Accidents are the leading cause of death between the ages of 1 and 35. About one third of all accidental deaths and one seventh of all accidental injuries are caused by motor vehicles. Based on the present rate of vehicle registration, unless the accident rate is cut in half, one of every 10 persons in the country will be killed or injured in a traffic accident in the next 15 years. Research to find the underlying causes of accidents and to develop ways to detect drivers who are apt to cause them is being conducted at universities and medical centers. Here are some of their findings so far: A man drives as he lives. If he is often in trouble with collection agencies, the courts, and police, chances are he will have repeated automobile accidents. Accident repeaters usually are egocentric, exhibitionistic, resentful of authority, impulsive, and lacking in social responsibility. As a group, they can be classified as borderline psychopathic personalities, according to Dr. McFarland. The suspicion, however, that accident repeaters could be detected in advance by screening out persons with more hostile impulses is false. A study at the University of Colorado showed that there were just as many overly hostile persons among those who had no accidents as among those with repeated accidents.
