单选题Continuing Medical Education There is increasing recognition of the need for health workers to continue their education throughout their careers. Not only do health workers themselves wish to improve their own skills and competence, but the introduction of new techniques and equipment and the changes taking place in health needs and health care policies necessitate continued training. The phrase "health care" is intended to mean not just curative treatment for the sick but the whole range of provision for promoting health and preventing disease. In virtually every situation some response to this need has been made, so continuing education does take place—even though it may in many instances be ineffective or insufficient. Continuing education may be initiated by the health workers themselves, by their supervisors, by the managers of the health system, or by other agencies such as professional associations, publishers, and drug companies. The form of the continuing education may be written materials (journals, books, advertisements), meetings, courses, supervisory visits, or a variety of other methods. With this diversity of approach it is not surprising that the effectiveness of the continuing education should be variable. So it is natural that in many countries there is a concern that more continuing education should be provided and that it should be more effective. The approach suggested that to achieve this aim is to develop a "system" of continuing education. This term needs some explanation as it is capable of being interpreted in many ways. A system is not the same thing as an organization that provides continuing education. It is much more than that. It is the sum of the educational activities, the organizational structure that supports and manages those activities, the management, and the external agencies involved in the provision of health care. The system should comprise a nationwide coordinated program in which technology and resources are optimally used.

单选题Computer crimes More and more, the operations of our business, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap substantial rewards. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment. It's easy for computer crimes to go undetected if no one checks up on what the computer is doing, but even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected but it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck. For example, a certain keypunch operator complained of having to stay overtime to punch extra cards, investigation revealed that' the extra cards she was being asked to punch were for dishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that was being robbed unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met. Why? Because company executives are afraid of the bad publicity that would result if the public found out their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.

单选题Internet Internet use appears to cause a drop in psychological health, according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more bad feelings and loneliness than those who was online less frequently, the two-year study showed. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to commnunicate with others. The fact that Internet use reduces time available for family and friends may account for the drop in psychological health, researchers hypothesized (推测). Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives. "But it's important to remember this is not about the technology, it's about how it is used," says psychologist Christine Riley of Intel, one of the study's sponsors. "It really points to the need for considering social factors in terms of how you design applications and services for technology. /

单选题After-birth Depression Blamed for Woman"s Suicide A new mother apparently suffering from postpartum mental illness fell to her death from a narrow 12th-floor ledge of a Chicago hotel, eluding the lunging grasp of firemen called to help. The Chicago Tribune reported Tuesday that the mother of a 3-month-old daughter, Melanie Stokes, 41, was said to be suffering from a severe form of after-birth depression called postpartum psychosis, an extremely rare biological response to rapidly changing hormonal levels that can result in hallucinations, delusions, severe insomnia and a drastic departure from reality. "That was a monster in my daughter"s brain," said Stokes" mother, Carol Blocker. "The medicine took no effect at all, while her grief was so strong that nothing could make up for it. I"m just glad she didn"t take her daughter with her." Virtually all new mothers get postpartum blues, also called the "baby blues", which are brief episodes of irritability, moodiness and weepiness. About 20 percent of birthing women experience postpartum depression, which can be triggered by hormonal changes, sleeplessness and the pressures of being a new mother. It is often temporary and highly treatable. But The Tribune said what scientists suspect Stokes was battling, postpartum psychosis, is even more extreme and is considered a psychiatric emergency. During postpartum psychosis—a very real disorder that affects less than 1 percent of women, according to the National Institute of Mental Health—a mother might hear voices, have visions, feel extremely agitated and be at risk of harming the child or herself. Often the consequences are tragic. In 1987, Sheryl Masip of California told a judge that postpartum psychosis made her drive a Volvo over her 6-week-old son. Latrena Pixley of Washington, D. C., said the disorder was why she smothered her 6-week-old daughter in 1922. And last year, Judy Kirby, a 31-year-old Indianapolis mother allegedly suffering from postpartum psychosis, sped into oncoming traffic and plowed into a minivan, killing seven youngsters, including three of her own.
