Italians are beginning to recognize the problem. Over the past decade, the government has passed laws targeting everything from workplace discrimination to accessibility requirements. A recent study by the European Union found that 85 percent of Italians admit that public transportation and infrastructure (基础设施) are inadequate for the handicapped, and 97 percent say action is needed. But the biggest barrier is psychological. “Italian companies are afraid of hiring disabled people,” says Chiapello. The only way to alter that, he says, is for Italy’s disabled to do what he did--- get out of the house and demand change. (318 words)

Passage Four

The average number of authors on scientific papers is sky-rocketing. That’s partly because labs are bigger, problems are more complicated, and more different subspecialties are needed. But it’s also because U.S. government agencies have started to promote “team science.” As physics developed in the post-World War Ⅱ era, federal funds built expensive national facilities, and these served as surfaces on which collaborations could crystallize naturally.

Yet multiple authorship --- however good it maybe in other ways --- presents for journals and for the institutions in which these authors work. For the journals, long lists of authors are hard to deal with in themselves. But those long lists give rise to more serious questions when something goes wrong with the paper. If there is research misconduct, how should the liability be allocated among the authors? If there is an honest mistake in one part of the work but not in others, how should an evaluator aim his or her review?
