单选题Motorola Inc., the world's second-largest mobile phone maker, will begin selling all of the technology needed to build a basic mobile phone to outside manufacturers, in a key change of strategy. The inventor of the call phone, which has been troubled by missteps compounded by a recent industry slump in sales, is trying to become a neutral provider of mobile technology to rivals, with an eye toward fostering a much larger market than it could create itself. The Chicago area-based company, considered to have the widest range of technologies needed to build a phone, said it planned to make available chips, a design layout for the computer beard, software, development tools and testing tools. Motorola has previously supplied mobile phone manufacturers with a couple of its chips, but this is the first time the company will offer its entire line of chips as well as a detailed blueprint. Mobile phones contain a variety of chips and components to control power, sound and amplification. Analysts .said they liked the new strategy but were cautious about whether Motorola's mobile phone competitors would want to buy the technology from a rival. The company, long known for its top-notch(等级) engineering culture, is hoping to profit from its mobile phone technology now that the basic technology to build a mobile phone has largely become a commodity. Motorola said it will begin offering the technology based on the next-generation GPRS (Global Packet Radio Service) standard because most mobile phone makers already have technology in place for current digital phones. GPRS offers faster access to data through "always on" network connections, and customers are charged only for the information they retrieve, rather than the length of download. Burgess said the new business will not conflict with Motorola's own mobile phone business because the latter will remain competitive by offering advanced features and designs. Motorola's phones have been criticized as being too complicated and expensive to manufacture, but Burgess said Motorola will simplify the technology in the phones by a third. In addition to basic technology, Burgess said, Motorola would also offer additional features such as Bluetooth, a technology that allows wireless communications at a short distance, and Global Positioning System, which tracks the user's whereabouts, and MP3 audio capability.

单选题Without fanfare or legislation, the government is orchestrating a quiet revolution in how it regulates new medicines. The revolution is based on the idea that the sicker people are, the more freedom they should have to try drugs that are not yet fully tested. For fifty years government policy has been driven by another idea: the fear that insufficiently tested medicines could cause deaths and injuries. The urgent needs of people infected with HIV, the AIDS virus, and the possibility of meeting them with new drugs have created a compelling countervailing force to the continuing concern with safety. As a result, government rules and practices have begun to change. Each step is controversial. But the shift has already gone far beyond AIDS. New ways are emerging for very sick people to try some experimental drugs before they are marketed. People with the most serious forms of heart disease, cancer, emphysema, Alzheimer' s or Parkinson' s disease, multiple sclerosis, epilepsy, diabetes, or other grave illnesses can request such drugs through their doctors and are likelier to get them than they would have been four years ago. "We've been too rigid in not making lifesaving drugs available to people who otherwise face certain death," says Representative Henry Waxman, of California, who heads the subcommittee that considers changes in drug-approval policies. "It's true of AIDS, but it's also true of cancer and other life- threatening diseases." For the first time, desperate patients have become a potent political force for making new medicines available quickly. People with AIDS and their advocates, younger and angrier than most heart-disease or cancer patients, are drawing on two decades of gay activists' success in organizing to get what they want from politicians. At times they found themselves allied with Reagan Administration deregulators, scientists, industry representatives, FDA staff members, and sympathetic members of Congress. They organized their own clinical trials and searched out promising drugs here and abroad. The result is a familiar Washington story: a crisis—AIDS—helped crystallize an informal coalition for reform. AIDS gave new power to old complaints. As early as the 1970s the drug industry and some independent authorities worried that the Food and Do, g Administration' s testing requirements were so demanding that new drugs were being unreasonably delayed. Beginning in 1972, several studies indicated that the United States had lost its lead in marketing new medicines and that breakthrough drugs—those that show new promise in treating serious or life-threatening diseases— had come to be available much sooner in other countries. Two high-level commissions urged the early release of breakthrough drugs. So did the Carter Administration, but the legislation it pro- posed died in Congress. Complaints were compounded by growing concern that "if we didn't streamline policies, red tape wot, Id be an obstacle to the development of the biotechnology revolution," as Frank E. Young, who was the head of the FDA from 1984 to 1989, put it in an interview with me. Young was a key figure in the overhaul of the FDA's policies. A pioneer in biotechnology and a former dean of the University of Rochester's medical school, he came to Washington with an agenda and headed the agency for five and a half years—longer than anyone else has since the 1960s. Young took the FDA job to help introduce new medicines created by biotechnology-- whose promise he had seen in his own gene-cloning lab--and to get experimental medicines to desperately iii people more quickly. He had seen people die waiting for new medicines because "they were in the wrong place at the wrong time," he said. That is now changing.
