单选题In general, our society is becoming one of giant enterprises directed by a bureaucratic management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, the blue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management. The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction or interest in life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings. Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the tight mixture of submissiveness and independence. From that moment on they are tested again and again by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one"s fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness. Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century "free enterprise" capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system from a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities—those of love and of reason—are the aims of all social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.

单选题The worsening crisis at the Fukushima Power Station in Japan has led to inevitable comparisons with the 1986 Chernobyl nuclear disaster that killed workers at the plant instantly, caused cancers in the surrounding population and spread radioactive contamination so far that livestock restrictions are still in place at some farms around the Ukraine. The situation at Fukushima is certainly grave and immediately dangerous for those at the site who are fighting to make the crippled reactors and fuel storage ponds safe. But whatever warnings are now being issued by foreign governments to their citizens in Japan, there are significant differences that set this apart from the catastrophe in Ukraine. At Chernobyl the nuclear reactor exploded after a surge in power that blew the top off the power plant and sent hot fuel high into the upper atmosphere, where it floated across national borders. A fire that broke out in the graphite core forced more radioactive material into the air, helping it spread further. The reactor had no containment facility to even slow the release of radiation from the plant. The Fukushima boiling water reactor is a 40-year-old power plant and it has some glaring design flaws, but the reactors have been switched off for five days, so there is less fresh radioactive material around, and each core is contained within a 20cm-thick steel container, which is then protected by a steel-lined reinforced concrete outer structure. Even in the case of a meltdown, these measures should at least limit the amount of radiation released. But what of the population beyond? The risk from radiation falls off substantially with distance. The authorities have already imposed an exclusion zone of 12 miles around the power station, introduced food bans and dispensed potassium iodide pills to those in the surrounding area. For the more distant population, the most serious radioactive substances that would be released are caesium-137 and iodine-131. These are extremely volatile, so can be carried a long way. But dangerous doses are not likely to travel far on the wind. The danger comes when radioactive iodine and caesium rain down on the ground, on the pastureland, for example, and livestock eat it. Cows concentrate radioactive iodine in their milk. Radioactive caesium accumulates in muscles, and in the past has built up in grazing sheep. The threat to humans then comes from drinking milk and eating contaminated meat. Both can raise the risk of cancer—iodine especially by being absorbed into children"s thyroid glands. What happened at Chernobyl, which was a much more serious accident than this, was that the local Soviet authorities were in denial, they didn"t get people out of the area, they didn"t evacuate quickly enough, and they allowed children to continue to drink heavily contaminated milk, and as a consequence, many children received high doses of radiation to the thyroid and we"ve seen thousands of thyroid cancers as a consequence.

单选题There is extraordinary exposure in the United States to the risks of injury and death from motor vehicle accidents. More than 80 percent of all households own passenger cars or light trucks and each of these is driven an average of more than 11,000 miles each year. Almost one-half of fatally injured drivers have a blood alcohol concentration (BAC) of 0.1 percent or higher. For the average adult, over five ounces of 80 proof spirits would have to be consumed over a short period of time attain these levels. One third of drivers who have been drinking, but fewer than 4 percent of all drivers, demonstrate levels. Although less than 1 percent of drivers with BACs of 0.1 percent or more are involved in fatal crashes, the probability of their involvement is 27 times higher than for those without alcohol in their blood. There are a number of different approaches to reducing injuries in which intoxication plays a role. Based on the observation that excessive consumption correlates with the total alcohol consumption of a country"s population, it has been suggested that higher taxes on alcohol would reduce both. While the heavier drinkers would be taxed the most, anyone who drinks at all would be penalized by this approach. To make drinking and driving a criminal offense is an approach directed only at intoxicated drivers. In some states, the law empowers police to request breath tests of drivers cited for any traffic offense and elevated BAC can be the basis for arrest. The National Highway Traffic Safety Administration estimates, however, that even with increased arrests, there are about 700 violations for every arrest. At this level there is little evidence that laws serve as deterrents to drinking while intoxicated. In Britain, motor vehicle fatalities fell 25 percent immediately following implementation of the Road Safety Act in 1967. As the British increasingly recognized that they could drink and not be stopped, the effectiveness declined, although in the ensuing three years the fatality rate seldom reached that observed in the seven years prior to the Act. Whether penalties for driving with a high BAC or excessive taxation on consumption of alcoholic beverages will deter the excessive drinkers responsible for most fatalities is unclear. In part, the answer depends on the extent to which those with high BACs involved in crashes are capable of controlling their intake in response to economic or penal threat. Therapeutic programs which range from individual and group counseling and psychotherapy to chemotherapy constitute another approach, but they have not diminished the proportion of accidents in which alcohol was a factor. In the few controlled trials that have been reported there is little evidence that rehabilitation programs for those repeatedly arrested for drunken behavior have reduced either the recidivism or crash rates. Thus far, there is no firm evidence that Alcohol Safety Action Project supported programs, in which rehabilitation measures are requested by the court, have decreased recidivism or crash involvement for clients exposed to them, although knowledge and attitudes have improved. One thing is clear, however: unless we deal with automobile and highway safety and reduce accidents in which alcoholic intoxication plays a role, many will continue to die.
