His novel , U. S. A. Trilogy , which is John Dos Passos’s masterpiece, mirrors the dark side of America and revals the essence of the society, marking a higher level of John Dos Passos’s artistic achievements.This thesis tends to explore the themes of U. S. A. Trilogy from three chapters. Chapter one deliberates the theme—the pursuit of money, which is mainly formed by Charley’s pursuit of money and Moorehouse’s pursuit of money. Chapter two elaborates the theme—the protest against the society from two angles—Savage’s p rotest and Mary’s protest.Chapter three investigates the theme—the compromise on the destiny including Charley’s compromise on career and spirit and Margo’s compromise on dream and life.In conclusion, in U. S. A. Trilogy, employing the unique narrative art, John Dos Passos creates insightful themes—the pursuit of money, the protest against the society and the compromise on the destiny. Themes reflect the distorted effects of capitalism on the American people, which is of great realistic significance in modern society. Consequently, U. S. A. Trilogy enlightens that people should be brave, hard-working and hopeful so as to fabricate a more harmonious society.Key Words: John Dos Passos money protest compromise摘要约翰•多斯•帕索斯,是一位美国杰出的的文学家。

外研社美国文学史及选读(第三版)(第二册)教学课件0 Part V-Introduction
After the First World War a group of new American dramatists emerged, and the American theater ceased to be wholly dependent on the dramatic traditions of Europe. Experimental playwrights, hostile to outworn and timid theatrical convention, created works of tragedy, stark realism, and social protest. Early in the 1920s the most prominent of the new American playwrights, Eugene Gladstone O’Neill, established an international reputation with such plays as The Emperor Jones (1920) and The Haiuction
Waste Land, the most significant American poem of the 20th century, helped to establish a modern tradition of literature rich with learning and allusive thought.
ICnhatprtoerd3uction
American society. Early in the century Ezra Pound and T. S. Eliot published works that would change the nature of American poetry, but their impact (and that of other modernist writers) on the general reading public was slight. The genteel tradition and popular romanticism still dominated the nation’s literary tastes.

Introduction 引言;前言;绪言The opening decade of the twenty-first century has been overwhelmingly shaped by the American and world response to the terror attacks of 11 September 2001.Many analysts speak of a paradigm shift in foreign policy alignments, global economies, and domestic affairs.The events of the post (=late)-11 September world make the 1990s seem a vast, quaint (奇怪的) universe away.But we should note that analysts had christened (洗礼仪式) the last decade of the twentieth century as a “New World Order” u nder the common umbrella of democracy and free market capitalism.Certainly the decade marked a decisive end to the “post (after)-World War II” or “Cold War” world and ushered in a new era.The 45-year period following the dropping of atomic bombs on Hiroshima and Nagasaki the, division of the world into “free”and “communist”influences, and the collapse of the Berlin Wall in 1989 changed things.The world is still adjusting to those changes and countries rush (run) to realign (重新排列, 再结盟) the geopolitical order.美国和世界对于2001年9月11日恐怖袭击的反应已经压倒性地充斥了21世纪的头十年。

当代研究生英语读写教程(上) A课文译文第一单元信息空间:出入随愿1 美国人的内心深处具有一种酷爱探索新领域的气质。

我们渴求宽敞的场地,我们喜欢探索,喜欢制定规章制度,却不愿去遵守。

在当今时代,却很难找到一块空间,可以供你任意驰骋,又不必担心影响你的邻居。

2 确实有这样一个空间,那就是信息空间。

这里原本是计算机迷的游戏天地,但如今只要想像得到的各类人群应有尽有,包括少年儿童、轻佻的单身汉、美籍匈牙利人、会计等。

问题是他们都能和睦相处吗?人们是否会因为害怕孩子们躲在卧室里看网上的淫秽图片而将它封杀?3 首先要解决的问题是,什么是信息空间。

我们可以抛开高速公路、前沿新领域等比喻,把信息空间看作一个巨大的房地产。

请记住,庄园是人们智慧的结晶,是合法的、人工营造的氛围,它建立在土地之上。

在房地产业中,公园和商业中心、红灯区与学校、教堂、政府机构与杂货店都能区分开来。

4 你可以用同样的方法把信息空间想像为一个巨大的、无边无际的虚拟房地产业。

其中有些房产为私人拥有并已租出,有些是公共场所;有的场所适合儿童出人,而有些地方人们最好避开。

遗憾的是,正是这些应该避开的地方使得人们心向神往。

这些地方教唆你如何制造炸弹、为你提供淫秽材料、告诉你如何窃取信用卡。

所有这些使信息空间听起来像是一个十分肮脏的地方。

正直的公民纷纷作出这样的结论:最好对它严加管理。

5 但是,在利用规章制度来反击下流之举之前,关键是从根本上理解信息空间的性质。

恶棍并不能在信息空间抢走毫无提防之心的儿童;信息空间也不像一台巨大的电视机,向不情愿的观众播放令人作呕的节目。

在信息空间这个房地产业中,用户对他们所去之处、所见所闻、所做所为都要作出选择,一切都出于自愿。

换句话说,信息空间是个出入自便的地方,实际上,信息空间里有很多可去之处。

人们不能盲目上网,必须带着具体的目标上网。

这意味着人们可以选择去哪个网址、看什么内容。

不错,规章制度应该在群体内得以实施,但这些规章制度必须由信息空间内各个群体自己来制定,而不是由法庭或华盛顿的政客们来制定。

Unit 1:cyberspace :if you don't love it ,leave itsomething in the American psyche loves new frontiers. We hanker after wide-open spaces ;we like to explore ;we like to make rules but refuse to follow them .But in this age it's hard to find a place where you can go and be yourself without worrying about he neighbours .There is such a place : cyberspace . Formerly a playground for computer fans ,cyberspace . Formely a playground for computer fans ,cyberspace now embraces everyconceivableconstituency:schoollchildren,flirtatious ,singles,Huganan-Americana accountants.Can they all get along?Or will our fear of kids surfing for dirty pictures behind their bedroom doors provoke a crackdown ?The first order of business is to grasp what cyberspace is . It might help to leave beind metaphors 隐喻of highways and frontiers and to think instead of real estate . Real estate ,remember ,is an intellectual ,legal ,artificial environment constructed on top of land. Real estate recognizes the difference between parkland and shopping mall ,between red-light zone and school district ,between church ,state and drugstore .in the same way , you could think of cyberspace as a giant and unbounded world of virtual real estate .Some property is privatedly owned and rented out ; other property is common land ; some places are suitable for children , and others are best avoided by all citizens . Unfortunately ,it's those places that are now capturing the popular imagination ,plaecs that offer bombmaking instructions ,pornography, advice on how to steal credit cards .They make cyberspace sound like a nasty place . Good citizens jump to a conclusion : Better regulate it .But before using regulations to counter indecency ,it is fundamental to interpret the nature of cyberspace . Cyberspace isn't a frontier where wicked people can grab unsuspecting children ,nor is it a giant television system that can beam offensive messages at unwilling viewers . In this kind of real estate ,users have to choose where thy visit ,what they see ,what they do .It's optiona .In other words,cyberspace is a voluntary destination --in reality ,many destinations .You don't just get "onto the Net" ;you have to go someplace in particular . That means that people can choose where to go and what to see .Yes , community standards should be enforced ,but those standards set by cyberspace communities themselves ,not by the courts or by politicians in Washington . what makes cyberspace so alluring is precisely the way in which it's different from shopping malls , television ,highways and other terrestrial jurisdictions.But let's define the territor:First ,there are private e-malil conversations ,similar to the conversations you have over the teleophone .These are private and consensualand require no regulation at all .Second , there are information and entertainment services , wehre people can download anytihing from legal texts and lists of "great new restaurants " to game software or dirty pictures . These places are like bookstores ,malls and movie houses --places whre you go to buy something .The customer needs to request an item or sign up for a subscription; stuff (especially pornography ) is not sent out to people who don't ask for it .Some of these services are free or included as part of a broader service like ComputerServe or America Online ; others charge may and may bill their customers directly .Third ,there are "real" communities ---groups of people who communicate among themselves . In real-estate terms ,they're like bars or restaurants or bathhouses . Each active participate contributes to a general conversation ,generally through posted messages . Other participant may simply listen or watch .Some services are supervised by a moderator ; others are more like bulletin boards ---anyone is free to post anything .Many of these services started out unmoderated but are now imposing rules to keep out unwanted advertising ,extraneous discussions or increasingly rude participants .Cyberspace communitis evolve just the way terrestrial ommunities do : people with like-minded interests band together . Every cyberspace community has its own character . Overall , the communities on CompuServe tend t be more professsional ; those on AmericaOnline , affluent young singles ;Prodigy family-oriented itself there are lots of passionate non-commercial discussion groups on topics ranging from Hungarian politics (hungary Online ) copyright law .What's unique about cyberspace is that it allows communities of any size and kind to flourish ; in cyberspace ,communities are chosen by the users , not forced on them by accidents of geography . This freedom gives the rules that precise in cyberspace a moral authority that rules in terrestrial environments don't have . Most people are stuck in the country of their birth, but if you don't like the rules of a given cyberspace community ,they can restrict their children's access to it .What's likely to happen in cyberspace is the formation of new communities ,free of the constraits that cause conflict on earth . Instead of a global village ,which is a nice dream but impossible to manage , we'll hae invented another world of self-contained communities that cater to their own members' inclinations without interfering with anyoneelse's The possibility of a real market-style evolution of governance is at hand .In cyberpace ,we'll be able to test and evolve rules governing wht needs to be governed --intellectual property ,content and access control , rules about privacy and free speech .Some communities will allow anyone in ;others will restrict access to members who qualify on one basis or another .Those communites that prove self-sustaining will prosper (and perhaps grow and split into subsets wiht ever-more-particular interests and identities ) Those that can't survive --either because people lose interest or get scared off --will simply wither away .In the near future ,explorers in cyberspace will need to get better at defining and identifying their communities . they will need to put in place --and accept ---their own local governments apart from terrestrial governments ,just as the owners of expensive real estatet often have their own security guards though they can call in the police to get ride of undesirable customers .Then what shoul be done about undesirable material in cyberspace ? What to do ,for instance ,about pornography . The answer is labeling ,besides banning ,questionable material .it makes sense for cyberspace participants themselves to agree on a scheme for uestionable items ,so that people or automatic filters can avoid them . It's easy enough for software manufacturers to build an automatioc filter that would prevent you or your child from ever seeing the undesired item on a menu . (it's as if all the items were wrapped , with labels on the wrapper.)Someone who posted pornographic material under the title "Kid-Fun" could be sued for mislabeling .Without a lot of fanfare , private enterprises and local groups are already producing a variety of labeling services ,along with kid-oriented sites like Kidlink and Kid's Space .People differ in their tastes and values and can find services on the Net that suit them in the same way they select books and magazines . Or they can wonder freely if they prefer , making up their own itinerary .In the end , our society needs to grow up . Growing up means understanding thtat there are no perfect answers , no all-purpose solutions , no government sanctioned safe havens .We haven't created a perfect society on earth , and we won't have one in cyberspace either . But at least we can have individual choice and individual responsibility .接converstion is seen as corss-cultural commuicayion allows us to understand the problem and forge solutuions without blaming either party.Once the problem is understood,improvement comes naturally.Wowen who feel abandoned and deprived when their husbands won‟t listen to or report daily news may be happy to deiscover their husbands trying to adapt once they understand the place of small talk in women‟s relationships.But if their husband don‟t adapt,the women may still be comforted that for men,this is not a failture of intimacy.Accepting the difference,the wives may look to their friends or faminly for that kind of talk.And husbands who can‟t provide it shouldn‟t fell their wives have made unreasonable demands.Some couples will still decide to divorce,but at least their decisions will be based on realistic expectations. Unit 2 WHY IS IT SO HARD FOR MEN AND WOMEN TO TALKI was addressing a small gathering in a suburban Virginia living room -- a women's group that had invited men to join them. Throughout the evening, one man had been particularly talkative, frequently offering ideas and anecdotes,while his wife sat silently beside him on the couch. Toward to end of the evening, I commented that women frequently complain that their husbands do not talk to them. This man quickly concurred. He gestured toward his wife and said, "She is the talker in our family." The room burst into laughter; the man looked puzzled and hurt. "It is true," he explained. "When I come home from work I have nothing to say. If she did not keep the conversation going, we would spend the whole evening in silence."This episode crystallizes the irony that although American men tend to talk more than women in public situations, they often talk less at home. And this pattern is wreaking havoc with marriage.Sociologist Catherine Kohier Riessman, who reported in her new book Divorce Talk that most of the women she interviewed -- but only a few of the men -- give the lack of communication as the reason for their divorces.In my own research, complaints from women about their husbands most often focused not on tangible inequities such as having give up the chance for a career to accompany a husband to his, or doing far more than their share of daily life. Instead, they focused on communication:"He does not listen to me," "He does not talk to me." I found that most wives want their husbands to be, first and foremost, conversational partners, but few husbands share this expectation of their wives.In short, the image that represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face, while a woman glares at the back of it, wanting to talk.Linguistic Battle Between Men and Women How can women and men have such different impressions of communication in marriage? Why is there a widespread imbalance in their interests and expectations?In the April 1990 issue of American Psychologist, Stanford University's Eleanor Maccoby reports the results of her own and others' research showing that children's development is most influenced by the social structure of peer interaction. Boys and girls tend to play with children of their own gender, and their sex-separate groups have different organizational structures and interactive norms.I believe that systematic differences in childhood socialization make talk between women and men like cross-cultural communication. My research on men's and women's conversations uncovered patterns similar to those described for children's groups.For women, as for girls, intimacy is the fabric of the relationships, and talk is the thread from which is woven. Little girls create and maintain friendships by exchanging secrets; similarly, women regard conversation as the cornerstone of friendship. So a woman expects her husband to be a new and improved version of a best friend. What is important is not the individual subjects that are discussed but the sense of closeness, of a life shared, that emerges when people tell their thoughts, feelings, and impressions.Bonds between boys can be as intense as girls', but they are based less on taking more on doing things together. Since they do not assume talk is the cement that binds a relationship, men do not know what kind of talk women want, and they do not miss it when it is not there.Boys' groups are larger, more inclusive, and more hierarchical, so boys must struggle to avoid the subordinate position in the group. This may play a role in women's complaints on men do not listen to them.Often when women tell men,"You are not listening," and the men protest "I am", the men are right. The impression of not listening results from misalignments in the mechanics conversation. This misalignments begins as soon as a man and a woman take physical position. When I studied videotapes made by psychologist Bruce Dorval of children and adults talking to their same-sex best friends, I found at every age, the girls and women faced each other directly, their eyes anchored on each other's faces. At every age, the boys and men sat at angles to each other and looked elsewhere in the room, periodically glancing at each other. But the tendency of men to face away can give women the impression they are not listening even when they are. A young woman in college was frustrated: whenever she told her boyfriend she wanted to talk to him, he would lie down on the floor, close his eyes, and put his arms over his face. This signaled to her, "He is taking a nap." But he insisted he was listening extra hard. Normally, he looks around the room, so he is easily distracted. Lying down and covering his eyes helped him concentrate on what she was saying.Switching topics is another habit that gives women the impression men are not listening, especially if they switch to a topic about themselves. The girls in my study tended to talk at length about one topic, but boys tended to jump from topic to topic.My study of the 10th-grade children found that when a girl told a friend about a problem, the friend responded by asking probing questions and expression agreement and understanding. But the boys dismissed each other's problems. Todd assured Richard that his drinking was "no big problem". And when Todd said he felt left out, Richard responded,"Why should you? You know more people than me."Women perceived such responses as belittling and unsupportive. But boys seemed satisfied with them. Whereas women reassured each other by implying, "You should not feel bad because I have had similar experiences," men do so by implying, "You should not feel bad because your problems are not so bad."There are even simpler reasons for women's impression that men do not listen. Linguist Lynette Hirschman found that women make more listener-noise, such as "mhm", "uhuh", and "yeah", to show "I am with you". Men, she found, more often give silent attention. Women who expect a stream of listener-noise interpret silent attention as no attention at all.Women's conversational habits are as frustrating to men as men's are to women. Men who expect silent attention interpret a stream of listener-noise as overreaction or impatience. Also, when women talk to each other in a close, comfortable setting, they often overlap, finish each other's sentences and anticipate what the other is about to say. This practice, which I call "participatory listenership", is often perceived by men as interruption, intrusion and lack of attention.A parallel difference caused a man to complain about his wife, "She just want to talk about her own point of view. If I show her another view, she gets mad at me." When most women talk to each other, they assume a conversationalist's job is to express agreement and support. But many men see their conversational duty as pointing out the other side of an argument. This is heard as disloyalty by women, and refusal to offer the requisite support. It is not that women do not want to see other points of view, but that they prefer them phrased as suggestions and inquires rather than as direct challenges.The Sounds of SilenceThese differences begin to clarify why women and men have such different expectations about communication in marriage. For women, talk creates intimacy. Marriage is an orgy of closeness: you can tell your feelings and thoughts, and still be loved. Their greatest fear is being pushed away. But men live in a hierarchical world, where talk maintains independence and status. They are on guard to protect themselves from bing put down and pushed around.This explains the paradox of the talkative man who said of his silent wife, "She is the talker." In the public setting, he felt challenged to show his intelligence and display his understanding. But at home, where he has nothing to prove and no one to defend against, he is free to remain silent. For his wife, being home means she is free from the worry that something she says might offend someone, or spark disagreement, or appear to be showing off; at home she is free to talk.The communication problems that endanger marriage can not be fixed by mechanical engineering. They require a new conceptual framework about the role of talk in human relationships. Many of the psychological explanations may not be helpful, because they tend to blame either women (for not being assertive enough) or men (for not being in touch with their feelings). A sociolinguistic approach by which male-femaleUnit 3: The Case Against ManThe first mistake is to think of mankind as a thing in itself. It isn‟t. It is part of an intricate web of life. And we can‟t think even of life as a thing in itself. It isn‟t. It is part of the intricate structure of a planet bathed by energy from the Sun.The Earth, in the nearly 5 billion years since it assumed approximately its present form, has undergone a vast evolution. When it first came into being, it very likely lacked what we would today call an ocean and an atmosphere. These were formed by the gradual outward movement of material as the solid interior settled together.Nor were ocean, atmosphere, and solid crust independent of each other after formation. There is interaction always: evaporation, condensation, solution, weathering. Far within the solid crust there are slow, continuing changes, too, of which hot springs, volcanoes, and earthquakes are the more noticeable manifestations here on the surface.Between 2 billion and 3 billion years ago, portions of the surface water, bathed by the energetic radiation from the Sun, developed complicated compounds in organization sufficiently versatile to qualify as what we call "life". Life forms have become more complex and more various ever since.But the life forms are as much part of the structure of the Earth as any inanimate portion is. It is all an inseparable part of a whole. If any animal is isolated totally from other forms of life, then death by starvation will surely follow. If isolated from water, death by dehydration will follow even faster. If isolated from air, whether free or dissolved in water, death by asphyxiation will follow still faster. If isolated from the Sun, animals will survive for a time, but plants would die, and if all plants died, all animals would starve.It works in reverse, too, for the inanimate portion of Earth is shaped and molded by life. The nature of the atmosphere has been changed by plant activity (which adds to the air the free oxygen it could not otherwise retain). The soil is turned by earthworms, while enormous ocean reefs are formed by coral.The entire planet, plus solar energy, is one enormous intricately interrelated system. The entire planet is a life form made up of nonliving portions and a large variety of living portions (as our own body is made up of nonliving crystals in bones and nonliving water in blood, as well as of a large variety of living portions).In fact, we can pursue the analogy. A man is composed of 50 trillion cells of a variety of types, all interrelated and interdependent. Loss of some of those cells, such as those making up an entire leg, will seriously handicap all the rest of the organism: serious damage to a relatively few cells in an organ, such as the heart or kidneys, may end by killing all 50 trillion.In the same way, on a planetary scale, the chopping down of an entire forest may not threaten Earth‟s life in general, but it will produce serious changes in the life forms of the region and even in the nature of the water runoff and, therefore, in the details of geological structure. A serious decline in the bee population will affect the numbers of those plants that depend on bees for fertilization, then the numbers of those animals that depend on those particular bee-fertilized plants, and so on.Or consider cell growth. Cells in those organs that suffer constant wear and tear—as in the skin or in the intestinal lining—grow and multiply all life long. Other cells, not so exposed, as in nerve and muscle, do not multiply at all in the adult, under any circumstances. Still other organs, ordinarily quiescent, as liver and bone, stand ready to grow if that is necessary to replace damage. When the proper repairs are made, growth stops.In a much looser and more flexible way, the same is true of the "planet organism" (which we study in the science called ecology). If cougars grow too numerous, the deer they live on are decimated, and some of the cougars die of starvation, so that their "proper number" is restored. If too many cougars die, then the deer multiply with particular rapidity, and cougars multiply quickly in turn, till the additional predators bring down the number of deer again. Barring interference from outside, the eaters and the eaten retain their proper numbers, and both are the better for it. (If the cougars are all killed off, deer would multiply to the point where they destroy the plants they live off, and more would then die of starvation than would have died of cougars.)The neat economy of growth within an organism such as a human being is sometimes—for what reason, we know not—disrupted, and a group of cells begins growing without limit. This is the dread disease of cancer, and unless that growing group of cells is somehow stopped, the wild growth will throw all the body structure out of true and end by killing the organism itself.In ecology, the same would happen if, for some reason, one particular type of organism began to multiply without limit, killing its competitors and increasing its own food supply at the expense of that of others. That, too, could end in the destruction of the larger system—most or all of life and even of certain aspects of the inanimate environment.And this is exactly what is happening at this moment. For thousands of years, the single species Homo sapiens, to which you and I have the dubious honor of belonging, has been increasing in numbers. In the past couple of centuries, the rate of increase has itself increased explosively.At the time of Jul ius Caesar, when Earth‟s human population is estimated to have been 150 million, that population was increasing at such a rate that it would double in 1000 years if that rate remained steady. Today, with Earth…s population estimated at about 4000 million (26 times what it was in Caesar‟s time), it is increasing at a rate which, if steady, will cause it to double in 35 years.The present rate of increase of Earth‟s swarming human population qualifies Homo sapiens as an ecological cancer, which will destroy the ecology just as surely as any ordinary cancer would destroy an organism.The cure? Just what it is for any cancer. The cancerous growth must somehow be stopped.Of course, it will be. If we do nothing at all, the growth will stop, as a cancerous growth in a man will stop if nothing is done. The man dies and the cancer dies with him. And analogously, the ecology will die and man will die with it.How can the human population explosion be stopped? By raising the death rate or by lowering the birthrate. There are no other alternatives. The death rate will rise spontaneously and finally catastrophically, if we do nothing—and that within a few decades. To make the birthrate fall, somehow (almost any how, in fact), is surely preferable, and that is therefore t he first order of mankind‟s business today.Failing this, mankind would stand at the bar of abstract justice (for there may be no posterity to judge) as the mass murderer of life generally, his own included, and mass disrupter of the intricate planetary development that made life in its present glory possible in the first place. Unit 5 Can We Know the Universe?Science is a way of thinking much more than it is a body of knowledge. Its goal is to find out how the world works, to seek what regularities there may be, to penetrate the connections of things—from subnuclear particles, which may be the constituents of all matter, to living organisms, the human social community, and thence to the cosmos as a whole. Our intuition is by no means an infallible guide. Our perceptions may be distorted by training and prejudice or merely because of the limitations of our sense organs, which, of course, perceive directly but a small fraction of the phenomena of the world. Even so straightforward a question as whether in the absence of friction a pound of lead falls faster than a gram of fluff was answered incorrectly by Aristotle and almost everyone else before the time of Galileo. Science is based on experiment, on a willingness to challenge old dogma, on an openness to see the universe as it really is. Accordingly, science sometimes requires courage—at the very least the courage to question the conventional wisdom.Beyond this the main trick of science is to really think of something: the shape of clouds and their occasional sharp bottom edges at the same altitude everywhere in the sky; the formation of the dewdrop on a leaf; the origin of a name or a word—Shakespeare, say, or "philanthropic"; the reason for human social customs—the incest taboo, for example; how it is that a lens in sunlight can make paper burn; how a "walking stick" got to look so much like a twig; why the Moon seems to follow us as we walk; what prevents us from digging a hole down to the center of the Earth; what the definition is of "down" on a spherical Earth; how it is possible for the body to convert yesterday's lunch into today's muscle and sinew; or how far is up—does the universe go on forever, or if it does not, is there any meaning to the question of what lies on the other side? Some of these questions are pretty easy. Others, especially the last, are mysteries to which no one even today knows the answer. They are natural questions to ask. Every culture has posed such questions in one way or another. Almost always the proposed answers are in the nature of "Just So Stories," attempted explanations divorced from experiment, or even from careful comparative observations.But the scientific cast of mind examines the world critically as if many alternative worlds might exist, as if other things might be here which are not. Then we are forced to ask why what we see is present and not something else. Why are the Sun and the Moon and the planets spheres? Why not pyramids, or cubes, or dodecahedra? Why not irregular, jumbly shapes? Why so symmetrical worlds? If you spend any time spinning hypotheses, checking to see whether they make sense, whether they conform to what else we know, thinking of tests you can pose to substantiate or deflate your hypotheses, you will find yourself doing science. And as you come to practice this habit of thought more and more you will get better and better at it. To penetrate into the heart of the thing—even a little thing, a blade of grass, as Walt Whitman said—is to experience a kind of exhilaration that, it may be, only human beings of all the beings on this planet can feel. We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.But to what extent can we really know the universe around us? Sometimes this question is posed by people who hope the answer will be in the negative, who are fearful of a universe in which everything might one day be known. And sometimes we hear pronouncements from scientists who confidently state that everything worth knowing will soon be known—or even is already known—and who paint pictures of a Dionysian or Polynesian age in which the zest for intellectual discovery has withered, to be replaced by a kind of subdued languor, the lotus eaters drinking fermented coconut milk or some other mild hallucinogen. In addition to maligning both the Polynesians, who were intrepid explorers (and whose brief respite in paradise is now sadly ending), as well as the inducements to intellectual discovery provided by some hallucinogens, this contention turns out to be trivially mistaken.Let us approach a much more modest question: not whether we can know the universe or the Milky Way Galaxy or a star or a world. Can we know, ultimately and in detail, a grain of salt? Consider one microgram of table salt, a speck just barely large enough for someone with keen eyesight to make out without a microscope. In that grain of salt there are about 1016 sodium and chlorine atoms. That is a 1 followed by 16 zeros, 10 million billion atoms. If we wish to know a grain of salt we must know at least the three-dimensional positions of each of these atoms. (In fact, there is much more to be known—for example, the nature of the forces between the atoms—but we are making only a modest calculation.) Now, is this number more or less than a number of things which the brain can know?How much can the brain know? There are perhaps 1011 neurons in the brain, the circuit elements and switches that are responsible in their electrical and chemical activity for the functioning of our minds. A typical brain neuron has perhaps a thousand little wires, called dendrites, which connect it with its fellows. If, as seems likely, every bit of information in the brain corresponds to one of these connections, the total number of things knowable by the brain is no more than 1014, one hundred trillion. But this number is only one percent of the number of atoms in our speck of salt.So in this sense the universe is intractable, astonishingly immune to any human attempt at full knowledge. We cannot on this level understand a grain of salt, much less the universe.But let us look a little more deeply at our microgram of salt. Salt happens to be a crystal in which, except for defects in the structure of the crystal lattice, the position of every sodium and chlorine atom is predetermined. If we could shrink ourselves into this crystalline world, we would rank upon rank of atoms in an ordered array, a regularly alternating structure—sodium, chlorine, sodium, chlorine, specifying the sheet of atoms we are standing on and all the sheets above us and below us. An absolutely pure crystal of salt could have the position of every atom specified by something like 10 bits of information. This would not strain the information-carrying capacity of the brain.If the universe had natural laws that governed its behavior to the same degree of regularity that determines a crystal of salt, then, of course, the universe would be knowable. Even if there were many such laws, each of considerable complexity, human beings might have the capability to understand them all. Even if such knowledge exceeded the information-carrying capacity of the brain, we might store the additional information outside our bodies—in books, for example, or in computer memories—and still, in some sense, know the universe.Human beings are, understandably, highly motivated to find regularities, natural laws. The search for rules, the only possible way to understand such a vast and complex universe, is called science. The universe forces those who live in it to understand it. Those creatures who find everyday experience a muddled jumble of events with no predictability, no regularity, are in grave peril. The universe belongs to those who, at least to some degree, have figured it out.For myself,I like a universe that includes much that is unknown and,at the same time,much that is knowable.A universe in which every thing is known would be static and dull,as boring as the heaven of some weak-minded theologians.A universe that is unknowable is no fit place for a thinking being.The ideal universe for us is one verymuch like the universe we inhabit.And I would guess that is not really much of a coincidence.。

The overall 7aim of the HSM is to reduce crashes and crash severities through the comparison and 8evaluation of alternative treatments and design of roadways. A commensurate 9objective is to use limited safety funds in a cost effective manner.10This chapter presents the following concepts:11An overview of the basic concepts relating to crash analysis, 12including definitions of key crash analysis terms, the difference 13between subjective and objective safety, factors that contribute to 14crashes and strategies to reduce crashes;15Data for crash estimation and its limitations;16A historical perspective of the evolution of crash estimation17methods and the limitations their methods;18An overview of the predictive method (Part C) and AMFs (Parts C 19and D);20Application of the HSM; and21The types of evaluation methods for determining the effectiveness 22of treatment types (Part B).23Users benefit by familiarizing themselves with the material in Chapter 3 in order 24to apply the HSM and understanding that engineering judgment is necessary to 25determine if and when the HSM procedures are appropriate.263.2.CRASHES AS THE BASIS OF SAFETY ANALYSIS27Crash frequency is used as a fundamental indicator of “safety” in the evaluation 28and estimation methods presented in the HSM. Where the term “safety” is used in 29the HSM, it refers to the crash frequency and/or crash severity and collision type for30a specific time period, a given location, and a given set of geometric and operational31conditions.32This section provides an overview of fundamental concepts relating to crashes 33and their use in the HSM:34The difference between objective safety and subjective safety;35The definition of a crash and other crash related terms;36Crashes are rare and random events;37Contributing factors influence crashes and can be addressed by a 38number of strategies;39This chapter introduces fundamentals for applying the HSM.Crash frequency is a fundamental quantitative performance measure in the HSM.Page 3-4 Part A / Introduction and FundamentalsThe HSM focuses on reducing crashes by changing the 40 roadway/environment.413.2.1.Objective and Subjective Safety42 The HSM focuses on how to estimate and evaluate the crash frequency and crash 43 severity for a particular roadway network, facility or site, in a given period, and 44 hence the focus is on “objective” safety. Objective safety refers to use of a quantitative 45 measure which is independent of the observer. Crash frequency and severity are 46 defined in Section 3.2.2.47 In contrast, “subjective” safety concerns the perception of how safe a person feels 48 on the transportation system. Assessment of subjective safety for the same site will 49 vary between observers.50 The traveling public, the transportation professional and the statisticians may all 51 have diverse but valid opinions about whether a site is “safe” or “unsafe.” Highway 52 agencies draw information from each of these groups in determining policies and 53 procedures which it will use to affect a change in crash frequency and/or severity 54 among the road or highway system.55 Exhibit 3-1 illustrates the difference between objective and subjective safety. 56 Moving to the right on the horizontal axis of the graph conceptually shows an 57 increase in objective safety (reduction in crashes). Moving up on the vertical axis 58 conceptually shows an increase in subjective safety (i.e., increased perception of 59 safety). In this exhibit, three examples illustrate the difference:60The change between Points A to A’ represents a clear-cut 61 deterioration in both objective and subjective safety. For example, 62 removing lighting from an intersection may increase crashes and 63 decrease the driver’s perception of safety (at night).64The change between Points B to B’ represents a reduction in the 65 perception of safety on a transportation network, For example, as a 66 result of a television campaign against aggressive driving, citizens 67 may feel less secure on the roadways because of greater awareness 68 of aggressive drivers. If the campaign is not effective in reducing 69 crashes caused by aggressive driving, the decline in perceived safety 70 occurs with no change in the number of crashes.71The change from Point C to C’ represents a physical improvement to 72 the roadway (such as the addition of left-turn lanes) that results in 73 both a reduction in crashes and an increase in the subjective safety.74Section 3.2.1 presents objective and subjective safety concepts. The HSM focuses on objective safety.Exhibit 3-1: Changes in Objective and Subjective Safety7576 Source: NCHRP 17-2777 3.2.2. Fundamental Definitions of Terms in the HSM78 Definition of a Crash79 In the HSM, a crash is defined as a set of events that result in injury or property 80 damage, due to the collision of at least one motorized vehicle and may involve 81 collision with another motorized vehicle, a bicyclist, a pedestrian or an object. The 82 terms used in the HSM do not include crashes between cyclists and pedestrians, or 83 vehicles on rails.(7) The terms “crash” and “accident” are used interchangeably 84 throughout the HSM.85 Definition of Crash Frequency86 In the HSM, “crash frequency” is defined as the number of crashes occurring at a 87 particular site, facility or network in a one-year period. Crash frequency is calculated 88 according to Equation 3-1 and is measured in number of crashes per year.89Years in Period Crashes of Number Frequency Crash =(3-1)90Definition of Crash Estimation91 “Crash estimation” refers to any methodology used to forecast or predict the 92crash frequency of:93An existing roadway for existing conditions during a past or future 94 period;95Section 3.2.2provides fundamentaldefinitions for usingAn existing roadway for alternative conditions during a past or9697future period;A new roadway for given conditions for a future period.9899The crash estimation method in Part C of the HSM is referred to as the 100“predictive method” and is used to estimate the “expected average crash frequency”, 101which is defined below.Definition of Predictive Method102103The term “predictive method“ refers to the methodology in Part C of the HSMthat is used to estimate the “expected average crash frequency” of a site, facility or 104105roadway under given geometric design, traffic volumes and for a specific period of 106time.Definition of Expected Average Crash Frequency107108The term “expected average crash frequency” is used in the HSM to describe the 109estimate of long-term average crash frequency of a site, facility or network under a 110given set of geometric design and traffic volumes in a given time period (in years).111As crashes are random events, the observed crash frequencies at a given site 112naturally fluctuate over time. Therefore, the observed crash frequency over a short 113period is not a reliable indictor of what average crash frequency is expected under 114the same conditions over a longer period of time.If all conditions on a roadway could be controlled (e.g. fixed traffic volume, 115116unchanged geometric design, etc), the long-term average crash frequency could be 117measured. However because it is rarely possible to achieve these constant conditions,the true long-term average crash frequency is unknown and must be estimated 118119instead.Definition of Crash Severity120Crashes vary in the level of injury or property damage. The American National 121122Standard ANSI D16.1-1996 defines injury as “bodily harm to a person”(7). The level of 123injury or property damage due to a crash is referred to in the HSM as “crashseverity.” While a crash may cause a number of injuries of varying severity, the term 124125crash severity refers to the most severe injury caused by a crash.126Crash severity is often divided into categories according to the KABCO scale,which provides five levels of injury severity. Even if the KABCO scale is used, the 127128definition of an injury may vary between jurisdictions. The five KABCO crashseverity levels are:129K - Fatal injury: an injury that results in death;130A - Incapacitating injury: any injury, other than a fatal injury, which131132prevents the injured person from walking, driving or normally 133continuing the activities the person was capable of performing 134before the injury occurred;B – Non-incapacitating evident injury: any injury, other than a fatal135injury or an incapacitating injury, which is evident to observers at 136137the scene of the accident in which the injury occurred;Page 3-6Part A / Introduction and FundamentalsC - Possible injury: any injury reported or claimed which is not a 138fatal injury, incapacitating injury or non-incapacitating evident 139injury and includes claim of injuries not evident;140O – No Injury/Property Damage Only (PDO).141While other scales for ranking crash severity exist, the KABCO scale is used in 142the HSM.143Definition of Crash Evaluation144In the HSM, “crash evaluation” refers to determining the effectiveness of a 145particular treatment or a treatment program after its implementation. Where the term 146effectiveness is used in the HSM, it refers to a change in the expected average crash 147frequency (or severity) for a site or project. Evaluation is based on comparing results 148obtained from crash estimation. Examples include:149Evaluating a single application of a treatment to document its 150effectiveness;151Evaluating a group of similar projects to document the effectiveness 152of those projects;153Evaluating a group of similar projects for the specific purpose of 154quantifying the effectiveness of a countermeasure;155Assessing the overall effectiveness of specific projects or 156countermeasures in comparison to their costs.157Crash evaluation is introduced in Section 3.7 and described in detail in Chapter 9. 1583.2.3.Crashes Are Rare and Random Events159Crashes are rare and random events. By rare, it is implied that crashes represent 160only a very small proportion of the total number of events that occur on the 161transportation system. Random means that crashes occur as a function of a set of 162events influenced by several factors, which are partly deterministic (they can be 163controlled) and partly stochastic (random and unpredictable). An event refers to the 164movement of one or more vehicles and or pedestrians and cyclists on the 165transportation network.166A crash is one possible outcome of a continuum of events on the transportation 167network during which the probability of a crash occurring may change from low risk 168to high risk. Crashes represent a very small proportion of the total events that occur 169on the transportation network. For example, for a crash to occur, two vehicles must 170arrive at the same point in space at the same time. However, arrival at the same time 171does not necessarily mean that a crash will occur. The drivers and vehicles have 172different properties (reaction times, braking efficiencies, visual capabilities, 173attentiveness, speed choice), which will determine whether or not a crash occurs.174The continuum of events that may lead to crashes and the conceptual proportion 175of crash events to non-crash events are represented in Exhibit 3-2. For the vast 176majority of events(i.e. movement of one or more vehicles and or pedestrians and 177cyclists) in the transportation system, events occur with low risk of a crash (i.e., the 178probability of a crash occurring is very low for most events on the transportation 179network).180 Crashes are rare – They represent only a very small proportion of the total number of events that occur on the transportation system.Crashes are random - They occur as a function of a set of events influenced by several factors.Page 3-8 Part A / Introduction and FundamentalsIn a smaller number of events, the potential risk of a crash occurring increases, 181 such as an unexpected change in traffic flow on a freeway, a person crossing a road, 182 or an unexpected object is observed on the roadway. In the majority of these 183 situations, the potential for a crash is avoided by a driver’s advance action, such as 184 slowing down, changing lanes, or sounding a horn.185 In even fewer events, the risk of a crash occurring increases even more. For 186 instance, if a driver is momentarily not paying attention, the probability of a crash 187 occurring increases. However, the accident could still be avoided, for example by 188 coming to an emergency stop. Finally, in only a very few events, a crash occurs. For 189 instance, in the previous example, the driver may have not applied the brakes in time 190 to avoid a collision.191 Circumstances that lead to a crash in one event will not necessary lead to a crash 192 in a similar event. This reflects the randomness that is inherent in crashes.193 Exhibit 3-2: Crashes are Rare and Random Events1941953.2.4.Crash Contributing Factors196 While it is common to refer to the “cause” of a crash, in reality, most crashes 197 cannot be related to a singular causal event. Instead, crashes are the result of a 198 convergence of a series of events that are influenced by a number of contributing 199 factors (time of day, driver attentiveness, speed, vehicle condition, road design etc). 200 These contributing factors influence the sequence of events (described above) before, 201 during and after a crash.202Before-crash events - reveal factors that contributed to the risk of a 203 crash occurring, and how the crash may have been prevented. For 204 example whether the brakes of one or both of the vehicles involved 205 were worn;206Section 3.2.4 introduces crash contributing factors.During-crash events – reveal factors that contributed to the crash 207208severity and how engineering solutions or technological changes 209could reduce crash severity For example whether a car has airbags 210and if the airbag deployed correctly;After-crash events – reveal factors influencing the outcome of the 211212crash and how damage and injury may have been reduced by 213improvements in emergency response and medical treatment For 214example the time and quality of emergency response to a crash.215Crashes have the following three general categories of contributing factors:Human – including age, judgment, driver skill, attention, fatigue, 216217experience and sobriety;Vehicle – including design, manufacture and maintenance;218Roadway/Environment – including geometric alignment, cross-219220section, traffic control devices, surface friction, grade, signage, 221weather, visibility.222By understanding these factors and how they might influence the sequence of 223events, crashes and crash severities can be reduced by implementing specific 224measures to target specific contributing factors. The relative contribution of these 225factors to crashes can assist with determining how to best allocate resources to reduce 226crashes. Research by Treat into the relative proportion of contributing factors is summarized in Exhibit 3-3(10). The research was conducted in 1980 and therefore, the 227228relative proportions are more informative than the actual values shown.229Exhibit 3-3: Contributing Factors to Vehicle Crashes2302311979TreatSource:232233A framework for relating the series of events in a crash to the categories of crashcontributing factors is the Haddon Matrix. Exhibit 3-4(2) provides an example of this 234235matrix. The Haddon Matrix helps create order when determining which contributingPage 3-10 Part A / Introduction and Fundamentalsfactors influence a crash and which period of the crash the factors influence. The 236 factors listed are not intended to be comprehensive; they are examples only.237Exhibit 3-4: Example Haddon Matrix for Identifying Contributing Factors238PeriodHuman FactorsVehicle FactorsRoadway/EnvironmentFactorsBefore Crash Factorscontributing to increased risk of crashdistraction, fatigue, inattention, poor judgment, age, cell phone use, deficient driving habits worn tires, worn brakeswet pavement, polished aggregate, steep downgrade, poorly coordinated signal systemDuring Crash Factorscontributing to crash severity vulnerability to injury, age, failure to wear a seat belt, driving speed, sobriety bumper heights and energy adsorption,headrest design, airbag operations pavement friction, grade, roadside environmentAfter Crash Factorscontributing to crash outcomeage, genderease of removal of injured passengersthe time and quality of the emergencyresponse, subsequent medical treatment239 Considering the crash contributing factors and what period of a crash event they 240 relate to supports the process of identifying appropriate crash reduction strategies. 241 Some examples of how a reduction in crashes and crash severity may be achieved 242 include:243 The behavior of humans;244 The condition of the roadway/environment;245 The design and maintenance of technology including vehicles, 246 roadway and the environment technology;247 The provision of emergency medical treatment, medical treatment 248 technology and post-crash rehabilitation;249The exposure to travel, or level of transportation demand.250 Strategies to influence the above and reduce crash and crash severity may 251 include:252Design, Planning and Maintenance - may reduce or eliminate 253 crashes by improving and maintaining the transportation system, 254 such as modifying signal phasing. Crash severity may also be 255 reduced by selection of appropriate treatments (such as the use of 256 median barriers to prevent head-on collisions).257 Education - may reduce crashes by influencing the behavior of 258 humans including public awareness campaigns, driver training 259 programs, and training of engineers and doctors.260Policy/Legislation – may reduce crashes by influencing human 261 behavior and design of roadway and vehicle technology. For 262 example laws may prohibit cell phone use while driving, require 263 minimum design standards, mandate use of helmets, and seatbelts.264The Haddon Matrix is a framework for identifying crash contributing factors.Enforcement – may reduce crashes by penalizing illegal behavior 265such as excessive speeding and drunken driving.266Technology Advances – may reduce crashes and crash severity by 267minimizing the outcomes of a crash or preempting crashes from 268occurring altogether. For example, electronic stability control 269systems in vehicles improve the driver’s ability to maintain control 270of a vehicle. The introduction of ”Jaws of Life” tools (for removing 271injured persons from a vehicle) has reduced the time taken to 272provide emergency medical services.273Demand Management/Exposure reduction – may reduce crashes 274by reducing the number of ‘events’ on the transportation system for 275which the risk of a crash may arise. For example, increasing the 276availability of mass transit reduces the number of passenger 277vehicles on the road and therefore a potential reduction in crash 278frequency may occur because of less exposure.279A direct relationship between individual contributing factors and particular 280strategies to reduce crashes does not exist. For example, in a head on crash on a two 281lane rural road in dry, well illuminated conditions, the roadway may not be 282considered as a contributing factor. However, the crash may have been prevented if 283the roadway was a divided road. Therefore while the roadway may not be listed as a 284contributing factor, changing the roadway design is one potential strategy to prevent 285similar accidents in the future.286While all of the above strategies play an important role in reducing crashes and 287crash severity, the majority of these strategies are beyond the scope of the HSM. The 288HSM focuses on the reduction of crashes and crash severity where it is believed that 289the roadway/environment is a contributing factor, either exclusively or through 290interactions with the vehicle and/or the driver.2913.3.DATA FOR CRASH ESTIMATION292This section describes the data that is typically collected and used for the 293purposes of crash analysis, and the limitations of observed crash data in the 294estimation of crashes and evaluation of crash reduction programs.2953.3.1.Data Needed for Crash Analysis296Accurate, detailed crash data, roadway or intersection inventory data, and traffic 297volume data are essential to undertake meaningful and statistically sound analyses. 298This data may include:299Crash Data: The data elements in a crash report describe the overall 300characteristics of the crash. While the specifics and level of detail of 301this data vary from state to state, in general, the most basic crash 302data consist of crash location, date and time, crash severity and 303collision type, and basic information about the roadway, vehicles 304and people involved.305Facility Data: The roadway or intersection inventory data provide 306information about the physical characteristics of the accident site. 307The most basic roadway inventory data typically include roadway 308classification, number of lanes, length, and presence of medians and 309 Typical data needs for crash analysis are: crash data, facility data, and traffic volume data.Page 3-12 Part A / Introduction and Fundamentalsshoulder width. Intersection inventories typically include road 310 names, area type, and traffic control and lane configurations.311Traffic Volume Data: In most cases, the traffic volume data 312 required for the methods in the HSM are annual average daily 313 traffic (AADT). Some organizations may use ADT (average daily 314 traffic) as precise data may not be available to determine AADT. If 315 AADT data are unavailable, ADT can be used to estimate AADT. 316 Other data that may be used for crash analysis includes intersection 317 total entering vehicles (TEV), and vehicle-miles traveled (VMT) on a 318 roadway segment, which is a measure of segment length and traffic 319 volume. In some cases, additional volume data, such as pedestrian 320 crossing counts or turning movement volumes, may be necessary.321 The HSM Data Needs Guide (9) provides additional data information. In addition, 322 in an effort to standardize databases related to crash analyses there are two 323 guidelines published by FHWA: The Model Minimum Uniform Crash Criteria 324 (MMUCC); and the Model Minimum Inventory of Roadway Elements (MMIRE). 325 MMUCC () is a set of voluntary guidelines to assist states in 326 collecting consistent crash data. The goal of the MMUCC is that with standardized 327 integrated databases, there can be consistent crash data analysis and transferability. 328 MMIRE ( ) provides guidance on what roadway inventory 329 and traffic elements can be included in crash analysis, and proposes standardized 330 coding for those elements. As with MMUCC, the goal of MMIRE is to provide 331 transferability by standardizing database information. 332 3.3.2.Limitations of Observed Crash Data Accuracy333 This section discusses the limitations of recording, reporting and measuring 334 crash data with accuracy and consistency. These issues can introduce bias and affect 335 crash estimation reliability in ways that are not easily addressed. These limitations 336 are not specific to a particular crash analysis methodology and their implications 337 require consideration regardless of the particular crash analysis methodology used.338 Limitations of observed crash data include:339 Data quality and accuracy340 Crash reporting thresholds and the frequency-severity 341 indeterminacy342Differences in data collection methods and definitions used by 343 jurisdictions344Data Quality and Accuracy345 Crash data are typically collected on standardized forms by trained police 346 personnel and, in some states, by integrating information provided by citizens self-347 reporting PDO crashes. Not all crashes are reported, and not all reported crashes are 348 recorded accurately. Errors may occur at any stage of the collection and recording of 349 crash data and may be due to:350 Data entry - typographic errors;351Imprecise entry - the use of general terms to describe a location;352Limitations of typical crash data are summarized in Section 3.3.2.。
