The student thieves on campus need to look out. With the emergence of a new web容不重複
site to help teachers
catch student plagiarists, these student thieves on campus have every reason to get worried.
Some students actually research and write their term papers in the old-fashioned way. 19 To prevent
collegiate copycats, two graduate students at the University of California at Berkeley have devised a program
that compares a student’s submission with every other term paper on the Web.
“We essentially search a hundred million web pages on the Internet, interfacing with the top 20 search
engines,” said John Barrie, of www.plagiarism.com. “We also compare that with our local database of term
papers.” Teachers who sign up can send their students’ papers to the website. 20 “We code every sentence
that was a word-for-word match with another sentence, either contained on the Internet or within our
database,” Barrie said. David Presti, a U.C. Berkeley professor who teaches neurobiology, told his class he
would use the program. Undaunted, numerous students plagiarized anyway. “We ran all 300 papers through
the program and found 45 of them, or 15 percent of students, had cut and pasted significant amounts of
material from various World Wide Web sites without citations,” Presti said. 21 They can show the
instructors “that indeed they haven’t got their material from the Internet or some other source,” Barrie said.
Competition is tough at prestigious universities like U.C. Berkeley. Some students welcome the Inter net research
watchdog, considering it a way to level the academic playing field. “I think it’s justified academically. Plagiarizing is
wrong,” one said.
19 Some universities are suing those companies that sell term papers over the Internet.
Others, however, just copy fake ones off the Internet and turn them in as their works.
Students falsely accused can have the opportunity to defend themselves.
The originality of the work, or lack thereof, becomes painfully clear within 24 hours.
20 While many students approve of going after the sellers of the term papers, others say the school should target
the students.
The teachers want the federal courts to enforce a law banning the sale of term papers.
Students falsely accused can have the opportunity to defend themselves.
The originality of the work, or lack thereof, becomes painfully clear within 24 hours.

Coffee is not usually thought of as health food, but a number of recent studies suggest that it can be a
highly beneficial drink. 22 Among them is a systematic review of studies published in 2005 in The Journal
of the American Medical Association, which concluded that habitual coffee consumption was associated with
a lower risk of Type 2 diabetes. 23
According to the authors, coffee contains antioxidants that help control cell damage that can contribute
to the development of the disease. It is also a source of chlorogenic acid, which has been shown in animal
experiments to reduce glucose concentration. 24 Studies that looked at decaffeinated coffee alone found
the same degree of risk reduction.
25 In a report that combined statistical data from many studies, researchers found that people who
drank four to six cups of coffee a day had a 28 percent reduced risk of diabetes compared with people who
drank two or fewer. Those who drank more than six had a 35 percent risk reduction.
22 Caffeine seems to have little to do with it.
The exact reason was not known, but the authors offered several explanations.
Researchers have found strong evidence that coffee reduces the risk of several serious ailments.
Researchers are surprised to learn that coffee is the major contributor of antioxidants.
