1 In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn’t any crime to worry about. Amazingly, these happy times appear still to be with us in the world’s biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors. SATAN can try out a variety of well-known hacking (黑客的) tricks on an Internet site without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle (闯入…...行窃). But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder. So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer. At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage. But let’s look on the bright side. Given the lack of locks, the Internet is surely the world’s biggest (almost) crime-free society. Maybe that is because hackers are fundamentally honest. Or that there currently isn’t much to steal. Or because vandalism ( 恶意破坏) isn’t much fun unless you have a peculiar dislike for someone. Whatever the reason, let’s enjoy it while we can. But expect it all to change, and security to become the number one issue, when the most influential inhabitants of the Net are selling services they want to be paid for. 2 I came away from my years of teaching on the college and university level with a conviction that enactment (扮演角色), performance, dramatization are the most successful forms of teaching. Students must be incorporated, made, so far as possible, an integral part of the learning process. The notion that learning should have in it an element of inspired play would seem to the greater part of the academic establishment merely silly, but that is nonetheless the case. Of Ezekiel Cheever, the most famous schoolmaster of the Massachusetts Bay Colony, his onetime student Cotton Mather wrote that he so planned his lessons that his pupils “came to work as though they came to play,” and Alfred North Whitehead, almost three hundred years later, noted that a teacher should make his/her students “glad they were there.” Since, we are told, 80 to 90 percent of all instruction in the typical university is by the lecture method, we should give close attention to this form of education. There is, I think, much truth in Patricia Nelson Limerick’s observation that “lecturing is an unnatural act, an act for which God did not design humans. It is perfectly all right, now and then, for a human to be possessed by the urge to speak, and to speak while others remain silent. But to do this regularly, one hour and 15 minutes at a time... for one person to drag on while others sit in silence?... I do not believe that this is what the Creator... designed humans to do.” The strange, almost incomprehensible fact is that many professors, just as they feel obliged to write dully, believe that they should lecture dully. To show enthusiasm is to risk appearing unscientific, unobjective; it is to appeal to the students’ emotions rather than their intellect. Thus the ideal lecture is one filled with facts and read in an unchanged monotone. The cult (推崇) of lecturing dully, like the cult of writing dully, goes back, of course, some years. Edward Shils, professor of sociology, recalls the professors he encountered at the University of Pennsylvania in his youth. They seemed “a priesthood, rather uneven in their merits but uniform in their bearing; they never referred to anything personal. Some read from old lecture notes and then haltingly explained the thumb-worn last lines. Others lectured from cards that had served for years, to judge by the worn edges... The teachers began on time, ended on time, and left the room without saying a word more to their students, very seldom being detained by questioners... The classes were not large, yet there was no discussion. No questions were raised in class, and there were no office hours.” 3 Take the case of public education alone. The principal difficulty faced by the schools has been the tremendous increase in the number of pupils. This has been caused by the advance of the legal age for going into industry and the impossibility of finding a job even when the legal age has been reached. In view of the technological improvements in the last few years, business will require in the future proportionately fewer workers than ever before. The result will be still further raising of he legal age for going into employment, and still further difficulty in finding employment when hat age has been attained. If we cannot put our children to work, we must put them in school. We may also be quite confident that the present trend toward a shorter day and a shorter week will be maintained. We have developed and shall continue to have a new leisure class. Already the public agencies for adult education are swamped by the tide that has swept over them since depression began. They will be little better off when it is over. Their support must come from the taxpayer. It is surely too much to hope that these increases in the cost of public education can be borne by the local communities. They cannot care for the present restricted and inadequate system. The local communities have failed in their efforts to cope with unemployment. They cannot expect to cope with public education on the scale on which we must attempt it. The answer to the problem of unemployment has been Federal relief. The answer to the problem of public education may have to be much the same, and properly so. If there is one thing in which the citizens of all parts of the country have an interest, it is in the decent education of the citizens of all parts of the country. Our income tax now goes in part to keep our neighbors alive. It may have to go in part as well to make our neighbors intelligent. We are now attempting to preserve the present generation through Federal relief of the destitute (贫民). Only a people determined to ruin the next generation will refuse such Federal funds as public education may require. 4 A new high-performance contact lens under development at the department for applied physics at the University of Heidelberg will not only correct ordinary vision defects but will enhance normal night vision as much as five times, making people’s vision sharper than that of cats. Bille and his team work with an optical instrument called an active mirror—a device used in astronomical telescopes to spot newly emerging stars and far distant galaxies. Connected to a wave-front sensor that tracks and measures the course of a laser beam into the eye and back, the aluminum mirror detects the deficiencies of the cornea, the transparent protective layer covering the lens of the human eye. The highly precise data from the two instruments—which, Bille hopes, will one day be found at the opticians (眼镜商) all over the world—serve as a basis for the production of completely individualized contact lenses that correct and enhance the wearer’s vision. By day, Bille’s contact lenses will focus rays of light so accurately on the retina (视网膜)that the image of a small leaf or the outline of a far distant tree will be formed with a sharpness that surpasses that of conventional vision aids by almost half a diopter ( 屈光度). At night, the lenses have an even greater potential. “Because the new lens—in contrast to the already existing ones—also works when it’s dark and the pupil is wide open,” says Bille, “lens wearers will be able to identify a face at a distance of 100 meters”—80 meters farther than they would normally be able to see. In his experiments night vision was enhanced by an even greater factor: in semi-darkness, test subjects could see up to 15 times better than without the lenses. Bille’s lenses are expected to reach the market in the year 2000, and one tentative plan is to use the Internet to transmit information on patients’ visual defects from the optician to the manufacturer, who will then produce and mail the contact lenses within a couple of days. The physicist expects the lenses to cost about a dollar a pair, about the same as conventional one-day disposable lenses. 5 On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more that they did in 1981. They also did more household work and participated in more of such organized activities as soccer and ballet (芭蕾舞). Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log hall that time. All in all, however, children’s leisure time dropped from 40% of the day in 1981 to 25% “Children are affected by the same time crunch (危机) that affects their parents,” says Sandra Hofferth, who headed the recent study of children’s timetable. A chief reason, she says, is that more mothers are working outside the home. (Nevertheless, children in both double-income and “male breadwinner” households spent comparable amounts of time interacting with their parents 19 hours and 22 hours respectively. In contrast, children spent only 9 hours with their single mothers.) All work and no play could make for some very messed-up kids. “Play is the most powerful way a child explores the world and learns about himself,” says T. Berry Brazelton, professor at Harvard Medical School Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it. The children sampled spent a quarter of their rapidly decreasing “free time” watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they’re spending less time in front of the TV set, however, kids aren’t replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let’s face it, who’s got the time? 6 Henry Ford, the famous U.S. inventor and car manufacturer, once said, “The business of America is business.” By this he meant that the U.S. way of life is based on the values of the business world. Few would argue with Ford’s statement. A brief glimpse at a daily newspaper vividly shows how much people in the United States think about business. For example, nearly every newspaper has a business section, in which the deals and projects, finances and management, stock prices and labor problems of corporations are reported daily. In addition, business news can appear in every other section. Most national news has an important financial aspect to it. Welfare, foreign aid, the federal budget, and the policies of the Federal Reserve Bank are all heavily affected by business. Moreover, business news appears in some of the unlikeliest places. The world of arts and entertainment is often referred to as “the entertainment industry” or “show business.” The positive side of Henry Ford’s statement can be seen in the prosperity that business has brought to U.S. life. One of the most important reasons so many people from all over the world come to live in the United States is the dream of a better job. Jobs are produced in abundance (大量地) because the U.S. economic system is driven by competition. People believe that this system crates more wealth, more jobs, and a materially better way of life. The negative side of Henry Ford’s statement, however, can be seen when the word business is taken to mean big business. And the term big business—referring to the biggest companies, is seen in opposition to labor. Throughout U.S. history working people have had to fight hard for higher wages, better working conditions, and the fight to form unions. Today, many of the old labor disputes are over, but there is still some employee anxiety. Downsizing—the laying off of thousands of workers to keep expenses low and profits high—creates feelings of insecurity for many. 7 Professor Smith recently persuaded 35 people, 23 of them women, to keep a diary of all their absent-minded actions for a fortnight. When he came to analyse their embarrassing lapses (差错) in a scientific report, he was surprised to find that nearly all of them fell into a few groupings, Nor did the lapses appear to be entirely random (随机的). One of the women, for instance, on leaving her house for work one morning threw her dog her earrings and tried to fix a dog biscuit on her ear. “the explanation for this is that the brain is like a computer,” explains the professor. “People programme themselves to do certain activities regularly. It was the woman’s custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the programme,” About one in twenty of the incidents the volunteers reported were these “programme assembly failures.” Altogether the volunteers logged 433 unintentional actions that they found themselves doing—an average of twelve each, There appear to be peak periods in the day when we are at our zaniest (荒谬可笑的). These are two hours some time between eight a.m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m. “Among men the peak seems to be when a changeover in brain ‘programmes’ occurs, as for instance between going to and from work.” Women on average reported slightly more lapses—12.5 compared with 10.9 for men—probably because they were more reliable reporters. A startling finding of the research is that the absent-minded activity is a hazard of doing things in which we are skilled. Normally, you would expect that skill reduces the number of errors we make. But trying to avoid silly slips by concentrating more could make things a lot worse—even dangerous. 8 It’s no secret that many children would be healthier and happier with adoptive parents than with the parents that nature dealt them. That’s especially true of children who remain in abusive homes because the law blindly favors biological parents. It’s also true of children who suffer for years in foster homes (收养孩子的家庭) because of parents who can’t or won’t care for them but refuse to give up custody (监护) rights. Fourteen-year-old Kimberly Mays fits neither description, but her recent court victory could eventually help children who do. Kimberly has been the object of an angry custody baffle between the man who raised her and her biological parents, with whom she has never lived. A Florida judge ruled that the teenager can remain with the only father she’s ever known and that her biological parents have “no legal claim” on her. The ruling, though it may yet be reversed, sets aside the principle that biology is the primary determinant of parentage. That’s an important development, one that’s long overdue. Shortly after birth in December 1978, Kimberly Mays and another infant were mistakenly switched and sent home with the wrong parents. Kimberly’s biological parents, Ernest and Regina Twigg, received a child who died of a heart disease in 1988. Medical tests showed that the child wasn’t the Twiggs’ own daughter, but Kimt only was, thus sparking a custody battle with Robert Mays. In 1989, the two families agreed that Mr. Mays would maintain custody with the Twiggs getting visiting fights. Those rights were ended when Mr. Mays decided that Kimberly was being harmed. The decision to leave Kimberly with Mr. Mays rendered her suit debated. But the judge made clear that Kimberly did have standing to sue (起诉) on her own behalf. Thus he made clear that she was more than just property to be handled as adults saw fit. Certainly, the biological link between parent and child is fundamental. But biological parents aren’t always preferable to adoptive ones, and biological parentage does not convey an absolute ownership that cancels all the rights of children. 9 In 1985 when a Japan Air Lines (JAL) jet crashed, its president, Yasumoto Takagi, called each victim’s family to apologize, and then promptly resigned. And in 1987, when a subsidiary of Toshiba sole sensitive military technology to the former Soviet Union, the chairman of Toshiba gave up his post. These executive actions, which Toshiba calls “the highest form of apology,” may seem bizarre to US managers. No one at Boeing resigned after the JAL crash, which may have been caused by a faulty Boeing repair. The difference between the two business cultures centers around different definitions of delegation. While US executives give both responsibility and authority to their employees, Japanese executives delegate only authority—the responsibility is still theirs. Although the subsidiary that sold the sensitive technology to the Soviets had its own management, the Toshiba top executives said they “must take personal responsibility for not creating an atmosphere throughout the Toshiba group that would make such activity unthinkable, even in an independently run subsidiary.” Such acceptance of community responsibility is not unique to businesses in Japan. School principals in Japan have resigned when their students committed major crimes after school hours. Even if they do not quit, Japanese executives will often accept primary responsibility in other ways, such as taking the first pay cut when a company gets into financial trouble. Such personal sacrifices, even if they are largely symbolic, help to create the sense of community and employee loyalty that is crucial to the Japanese way of doing business. Harvard Business School professor George Lodge calls the ritual acceptance of blame “almost a feudal (封建的) way of purging (清除) the community of dishonor,” and to some in the United States, such resignations look cowardly. However, in an era in which both business and governmental leaders seem particularly good at evading responsibility, many US managers would probably welcome an infusion (灌输) of the Japanese sense of responsibility. If, for instance, US automobile company executives offered to reduce their own salaries before they asked their workers to take pay cuts, negotiations would probably take on a very different character. 10 As machines go, the car is not terribly noisy, nor terribly polluting, nor terribly dangerous; and on all those dimensions it has become better as the century has grown older. The main problem is its prevalence, and the social costs that ensue from the use by everyone of something that would be fairly harmless if, say, only the rich were to use it. It is a price we pay for equality. Before becoming too gloomy, it is worth recalling why the car has been arguably the most successful and popular product of the whole of the past 100 years—and remains so. The story begins with the environmental improvement it brought in the 1900s. In New York city in 1900, according to the Car Culture, a 1975 book by J. Flink, a historian, horses deposited 2.5 million pounds of manure (粪) and 60,000 gallons of urine (尿) every day. Every year, the city authorities had to remove an average of 15,000 dead horses from the streets, it made cars smell of roses. Cars were also wonderfully flexible. The main earlier solution to horse pollutio
