Read each passage carefully, and then do the questions that follow. Choose the best answer from the four choices given and mark the corresponding letter with a single bar across the square brackets on your machine-scored Answer Sheet.Passage OneOne of the areas in which people tend to have ideas that don't make sense is that of rights. For example, many Americans believe that our rights, described in the Declaration of Independence and the Constitution, derive from God or from the very nature of being human, including the individual right to bear arms. Yet people in most law-governed democracies other than the United States do not have an individual right to bear arms. How, then, can the right to bear arms derive from God? Is this a special right that can be created by the people via government?It is claimed that we can trace the right to be armed to legal and political events in 17th century English history, this time relating to hunting and gaming laws. How does a fundamental natural right lie sleeping throughout the first 6,000 years of recorded history, only to wake to full flower due to conflicts over gaming laws in Restoration England? In the mid-1980s, the idea that people have a right to have consensual sex with partners of any gender was pronounced "joking inappropriately" by the Supreme Court; 25 years later it feels like an obvious, natural outgrowth of the Bill of Rights. If rights evolve this way through the dialectics of culture and history, just how "natural" can they be?Such are the idle thoughts that occur in the wake of America's latest episode of horrifying, meaningless mass slaughter. A large segment of the American public these days apparently finds it offensive to talk about gun control after these sorts of cruelty occur. As economist Mr. Wolfers said: "Let's not talk about gun control. It's too early, right? It's always too early. Except when it's too late."Mr. Wolfers is right: the "too early" construction is ridiculous. The only thing that is certain now is that gun control is uncertain in America. It's never going to happen. There are too many guns out there, and an individual right to bear arms is now established in constitutional law. So this is just what one of America's many faces is going to be: a bitterly divided, hatefully cynical country where insane people have easy access to semi-automatic weapons and occasionally use them to commit crime. We will continue to see more and more of this sort of thing, and there's nothing we can realistically do about it.1. The author begins by arguing that Americans' right to bear arms ______.A. is stipulated in the Constitution B. has been created by individuals C. has nothing to do with God D. is not to be doubted2. The Supreme Court is mentioned in Paragraph 2 to ______.A. confirm the validity of gun ownership by individuals B. argue that the right to bear arms is by no means natural C. prove that gun ownership has been approved by the Court D. describe the process of legislation on gun ownership3. The expression "in the wake of" used in the third paragraph probably means ______.A. butfor B. totally without C. soon after D. just before4. It seems to Mr. Wolfers that gun control is ______.A. really too early to start B. actually offensive C. not necessary now D. already too late5. It seems to the author that gun control in America is ______.A. impossible B. unconstitutional C. time-consuming D. stupid6. Which of the following might be an appropriate title for this passage?A. Gun Control Is Easy B. Gun Ownership Is Legal C. Gun Control, Too Late D. No Need to Control GunsPassage TwoThe English-speaking world does not look kindly on straw. Grasping at straws, straw-man arguments, the last straws and the straws that break so many camels' backs all demonstrate that. There is also a tale that straw is the worst material from which to build a house, particularly if you are a pig with a hungry wolf around. So the cards were stacked against Warren Brush when local officials learned that he had several buildings made of straw bales (大捆) on his land.They have tried to fine him. A lot. But the case is still unresolved. The problem is that California's building codes make no provision for the use of straw. And Mr. Brush has many defenders—among them several university scientists and David Eisenberg, chairman of the United States Green Building Council's code committee. They would like to see the prejudice against straw houses eliminated, for straw is, in many ways, an ideal building material.It is, for one thing, a great insulator. That keeps down the heating bills in houses made from it. It is also a waste product that would otherwise be burned, and is therefore cheap. And—very much to the point in a place like California—it is earthquake-resistant. Last year a test conducted at the University of Nevada showed that straw-bale constructions could withstand twice the amount of ground motion recorded in the Northridge earthquake that hit Los Angeles in 1994.California, of course, is already thoroughly earthquake-proofed. But straw buildings might do well in quake-prone places that are less wealthy. After a strong earthquake struck Pakistan in 2005, Darcey Donovan, a structural engineer from Truckee, California, set up a not-for-profit straw-bale-construction operation that has since built 17 houses there.There are, as it were, other straws in the wind: a post office in suburban Albuquerque, a Quaker school in Maryland, an office complex in suburban Los Angeles and an urban-renewal project in Binghamton, New York, have all been built from straw. Even California is having a rethink, and may change its rules to accommodate straw-bale construction. As Mr. Eisenberg observes, "the lesson of the Three Little Pigs isn't to avoid straw. It's that you don't let a pig build your house."1. By "the cards were stacked against Warren Brush," the author means that Brush ______.A. received punishment B. made a breakthrough C. might be highly praised D. would be in trouble2. David Eisenberg is mentioned ______.A. for the purpose of supporting Warren Bush B. as a representative of official opinions C. to provide evidence against straw houses D. to show the importance of the building codes3. What is Paragraph 3 mainly about?A. The structure of straw houses. B. The possibility of building straw houses. C. The advantages of straw houses. D. The tips for building straw houses.4. Which aspect of straw is emphasized in Paragraph 4?A. It is abundant in nature. B. It is rather inexpensive. C. It is a great insulator. D. It is easy to transport.5. It can be learned from the last paragraph that California ______.A. will fine Warren Brush as planned B. will reduce the fine on Warren Brush C. may lift the fine on Warren Brush D. may consider a bigger fine on Warren Brush6. The author's purpose in writing the passage is to ______.A. trace the evolution of straw houses B. explain how to build a house with straw C. highlight the prejudice against straw houses D. argue that straw can be used to build housesPassage ThreeI was talking with a senior Public Relations manager the other day about "The Game Trainers" and he expressed much skepticism about both the possibility and value of getting senior professionals to play games."These are serious people with serious jobs, and they are not going to waste time running around like school children," he told me. This statement highlighted many of his assumptions. It also provided me with a golden opportunity to talk about how these "serious people with serious jobs" could actually learn something about themselves, their company, and their business opportunities by allowing creativity to flow more freely through "games."His position is not uncommon and it comes from a deep seated misunderstanding of what a "game" is and what it is for, as well as a set notion of what "work" must look like for it to be considered of value. It's not a coincidence that the most successful companies of the last decade, including Apple and Google, were all started by college students, and perhaps as a consequence have a spirit of fun, creativity and innovation. Their success has not been achieved through a cubicle work environment, strict hierarchy, dull meetings and a 9 to 5 work structure. Instead they have flowing and flexible work spaces, a culture of collaboration, and opportunities for creativity.So where does the line between "work" and "game" occur? Well maybe there isn't one, or at least maybe there shouldn't be one. So is all this just a matter of perception? Well, yes and no. The starting point in allowing creativity to flow freely is to accept that the line between business and play is blurred, or at best non-existent. Only then is it possible to create the opportunity and appropriate environment for individuals and groups to play the game (or work) as well as they possibly can.The Game Trainers support this innovative and highly productive approach to work by creating games and group exercises to develop awareness and insight of issues, as well developing games to integrate into the working environment. And so, I said to the PR man, it's a good thing that they are "serious people with serious jobs," because we also are extremely serious about play, and in today's environment they simply cannot afford not to play games.1. What does the PR manager think of the author's proposal of playing games?A. It is probably nonsense. B. It is against the rule. C. It would be beneficial. D. It is worth a try.2. The author suggests that the PR manager's position on games ______.A. is hard to understand in today's world B. represents a common misunderstanding C. is based on scientifically proven concepts D. allows for greater work efficiency3. The examples of Apple and Google show that ______.A. games should be separated from work B. it helps to combine work with games C. work and games can be clearly defined D. no work can be done well without games4. What is the topic of Paragraph 4?A. How to draw a line between work and game? B. What is the line between work and game? C. Should there be a line between work and game? D. Why is there a line between work and game?5. "The Game Trainers" is probably a ______.A. computer game B. search engine C. research system D. game developer6. In this passage the author ______.A. encourages people to work more creatively B. describes how to balance work with life C. promotes an innovative approach to work D. analyzes why it is important to enjoy workPassage Four"A robot can't replace me," Andy Richter complained loudly but in good fun, facing the prospect of losing his job to the Jeopardy!-winning IBM's Watson computer. "A robot can't do the things a human can do. I mean, can he love, can he feel?"Well, no. But some folks are asking similar questions about computers such as Watson taking their jobs someday. "After all, if a machine can beat humans at Jeopardy!, will computers soon be competing with people for knowledge-based jobs?" asks Martin Ford, author of The Lights in the Tunnel in a Fortune magazine article. "If IBM's hopes for the technology are realized, workers may, in fact, have cause for concern."Ford and others argue that computers and robots such as Watson have the potential to replace not only assembly-line jobs, such as the manufacturing positions that dropped nationwide by one-third over the last decade, but the "knowledge worker" jobs of the modern economy, such as radiologists and lawyers. "Many of these people will be highly educated professionals who had previously assumed that they were, because of their skills and advanced educations, beneficiariesof the trend toward an increasingly technological and globalized world," Ford argues in his book.But Cornell University sociologist Trevor Pinch says that warnings about artificial intelligence taking over have missed essential shortcomings of computers for decades. "I would call them friendly monsters," he says, rather than job-killing ones. "Computers can never experience the things that make us uniquely human, they have never been delayed at O'Hare airport long enough to walk around the memorial to Gen. O'Hare, and have that memory stuck in your brain."Underneath the exaggerated publicity, the human brain far outperforms computers, and not just in raw calculating power, says information scholar Martin Hilbert of the University of Southern California in Los Angeles. All of the computers in the world taken together possess the computational power of, in all, 62 human brains, he says, based on findings his team reported this month in Science. There are about six billion people alive today.And hey, if things turn out as bad as Ford suggests, there is always the solution that Andy Richter settled on—beating anything that resembles the job-threatening Watson with a baseball bat. Let's hope it doesn't come down to that.1. We can learn that Jeopardy! is ______.A. a newly developed computer program B. a match between computers and humans C. a robot built with the latest technology D. a competition between fastest computers2. Paragraph 3 mainly discusses ______.A. the threat posed by tech development B. the potential benefits of digitalization C. the gap between blue-collar and white-collar jobs D. the way to survive knowledge-based economy3. In Paragraph 4, Trevor Pinch is talking about ______.A. man's advantages over computers B. advantages of computers over man C. the reliability of computers D. the future development of computers4. The sentence "There are about six billion people alive today" implies that ______.A. nobody should underestimate the power of computers B. we have enough manpower to fix existing problems C. computers can help human beings in all possible ways D. there is no need to worry too much about computers5. Who is most concerned about computers' taking over people?A. Martin Hilbert. B. Trevor Pinch. C. Martin Ford. D. Andy Richter.6. What does the author think of the prospect of jobs being lost to computers?A. It should be taken into serious consideration. B. We can always find solutions to the problem. C. It is too early to say anything for certain. D. We should always be ready for possible changes.Passage FiveThey are regarded as chores by both sexes, but fall disproportionately on only one. The latest survey of time use in America suggests women still shoulder most of the housework, spending on average an hour a day, compared with barely 20 minutes for the unfairer sex.Standard explanations for this division of labor rest on the pay gap between the sexes. A recent report shows women still earn about 20% less than men in America. But in a new paper, Leslie Stratton of Virginia Commonwealth University asks whether different attitudes to housework also play a role in sharing the dusting.Ms. Stratton draws on data from the 2000—2001 Time Use Survey in Britain, which shows how people spent their day and which tasks they enjoyed. Attitudes certainly differed: women disliked laundry less than men; ironing was extremely dreaded by both; strangely large numbers of both sexes liked shopping for food.Ms. Stratton found some evidence for the pay-gap hypothesis. Women with higher wages did a little less work at home. A woman who earned 10% more than average escaped doing two minutes' housework per weekday. Her partner heroically made up this time at the weekend. But his wages made no difference to the extent of his efforts around the house.The major determinant of how much housework a man did was how much he disliked it. Men who liked housework spent around 60% more time per weekday on it than those who were indifferent to it. Women's preferences seemed to have no effect on the time they spent on chores.One way to reduce the burden for both is to get help, although again the rewards are unevenly spread. He got away with 43% less housework at weekends, and she did 17% less. Almost all the extra housework generated by children was taken on by the woman. As children get older the weekday burden falls, but weekend time rises—and still comes mainly from her.There is truth in the idea that chores go to the lower-paid partner. But cause and effect are unclear. Do women do more because of lower pay, or might their careers suffer from a disproportionate burden at home? Evidence that only men's preferences seem to matter suggests the latter explanation should not be swept under the carpet.1. In a new paper, Leslie Stratton aims to ______.A. introduce some new ways for women to do less housework B. explain women's housework burden from a new angle C. challenge the survey that women still do most of the housework D. confirm the standard explanation for women's housework burden2. Which of the following tasks is disliked most by women?A. Laundry. B. Ironing. C. Shopping for food. D. Caring for babies.3. Ms. Stratton finds that the standard explanation for the division of labor ______.A. makes some sense B. lacks real evidence C. is truly well-grounded D. misses the point4. According to Paragraph 5, the division of labor is greatly affected by ______.A. the pay gap between the sexes B. the relationship between the sexes C. women's attitudes to housework D. men's preferences for housework5. What is the main idea of Paragraph 6?A. Men tend to benefit more from hired help. B. Women consider hired help especially useful. C. Getting help works equally well for both sexes. D. Getting help works better for families with kids.6. The author suggests in the last sentence of the passage that ______.A. the way housework is。

2012年12月英语四级真题及答案解析完整版

2012年12月英语四级真题及答案解析完整版Part I Writing【标准版】Nothing Succeeds Without a Strong WillNothing runs smoothly in our life. To achieve things successfully, a strong will is essential. Life is like a Marathon. Many people can’t get to the terminal. This is not bec ause they are lack of vitality but because their will of success is not strong enough.To take quitting smoking as an example, some regard it as a piece of cake. They make up their minds to quit it in the morning, but in the evening they feel that the smell of cigarettes is tempting. Their throats are sore, their mouths are thirsty, and their hands are shaking. After the painful mental struggle, they tell themselves that “One cigarette is enough. Just take one, and the next day I will quit it.” By doing this, they surrender to their weak will. In the end, they have quitted smoking “a hundred times”, but in no time they succeed.Just like quitting smoking, nothing succeeds without a strong will. To be successful in one’s life, a strong will means that you know where you go and you will persist on the road you choose. Undoubtedly success belongs to those who overcome their weak will and who hang in there until the last minute.【文章点评】本文属于话题类作文，只看题目“Nothing Succeeds without a strong will”考生会觉得比较抽象，难以下手。

在情景喜剧Seinfeld中，Krammer常常到Jerry的房间里自己仍冰箱里拿东西吃。

在Fri ends中，各种各样的剧中人经常不敲门就不假思索地进入别人的房间。

甚至有一次在伦敦，Ross突然进入Chandler的旅馆房间，差点儿撞见Chandler和Ross的妹妹的私情。

在20世纪50年代Leave It to Beaver热播的时代，并不值得为人们不锁门这一现象大惊小怪。

但在如今这个隐私和安全极受重视的时代，看到电视剧中的角色允许他人大摇大摆地进入自己的家中或房间中实在让人觉得难以置信。

类似地，在软件系统中，允许仸何人可以访问敏感或者私密的信息是不明智的。

应用系统必须通过质询来验证用户身份，据此决定是允许还是拒绝他访问受限制的信息。

无论你是通过用户名/密码来保护一个电子邮件账号，还是基于交易个人身份号码来保护一个佣金账户，安全性都是大多数应用系统的一个重要切面。

我们有意选择“切面”这个词来描述应用系统的安全性。

安全性是超越应用系统功能特性的一个关注点。

应用系统的绝大部分不应该亲自参与到与安全相关的处理中。

尽管你能够把与安全相关的处理直接编码到应用系统中（这种情况并不少见），但更好的做法还是将安全有关的关注点与应用系统的关注点分开。

如果你想到这听上去好像安全性是通过“面向切面”技术实现的，那你猜对了。

在本章中，我们将向你介绍Acegi安全系统，并探讨使用Spring AOP和Servlet 过滤器来保护应用系统的各种手段。

If you follow its advice, you cannot be open to criticism. If you do not, you may be criticised, and you may have marks deducted.The document contains advice about good style for legal writing, defines an acceptable house style for the use of footnotes, and outlines rules for the citation of primary and secondary legal sources.The importance of legal writingThe principal method of assessment in the Law School is written work whether by examination, assessed written work, or dissertation. Written work may take several different forms. You may be set a legal problem, or an essay, or you may be directed to write a letter, or a case note. This document contains general propositions applicable to all types of assessment, but is aimed particularly at word-processed answers. Matters of document style for assessed coursework and seminar essays are dealt with in the Degree Programme Handbooks.Types of exerciseProblem QuestionsThese consist of a statement of facts, usually with the direction to 'Advise X [one of the parties]'. The aim will be to analyse the facts to identify the legal issue(s), and analyse the law to find the relevant legal rule(s). Next will be the application of the law to the issue(s), and reaching a conclusion. Remember Issues Rules Application Conclusion - IRAC.Essay QuestionsIRAC is often a good starting point for an essay involving doctrinal analysis of the law. Start with an introduction identifying the legal issue(s) raised in the essay title, review the law, state how the law affects the issue(s) and reach conclusions in particular pointing to any areas where the application of the law is problematic or in need of reform.ExaminationsExaminations are normally hand-written, not word-processed, and you are not expected to reach the standards of citation of sources set out in this document. However, some of what follows about planning, writing and revision will be relevant to examinations.You may be asked to produce some other type of exercise e.g. a report, a case note, a memorandum or a letter. If in doubt precisely what is required, look for a model, and if still in doubt, ask.2Assessment CriteriaWritten work is assessed according to published assessment criteria, of which you should be aware. Two important general criteria are relevance and a critical approach. What you write must be relevant to the question set. If the relevance of any material is not obvious, you must justify its inclusion. Essay type questions may call specifically for critical analysis, but, whatever the type of exercise it will seldom be sufficient to describe the law without identifying and commenting upon its strengths or shortcomings, i.e. providing a critique.PlanningPlanning is the key to effective writing. Plan your use of available time, dividing the task into manageable sub-tasks. The first stage is to think about the title or problem, in order to decide the scope and purpose of your answer. It may be appropriate to discuss your ideas with other students, in order to test your interpretation of the title. You may need to decide who your readers are and what they need to know. By default, assume you are writing for a lawyer without detailed knowledge of the topic under consideration.ResearchYou will need to discover information by conducting library research. Make full use of printed and electronic searching to find relevant sources. Electronic sources are usually available on demand, but printed materials may not be available when you want them especially if a large group is engaged on the same exercise. The Copyright Licensing Agency rules displayed besides photocopiers have to be complied with, and the Law School is not always able to provide photocopies of relevant materials. Make notes about your sources, including an accurate reference complying with the rules set out in this document. You are solely responsible for the accuracy of these references and for complying with the University's rules about plagiarism.WritingWhatever the task, your aim should be to write clearly, directly and succinctly, avoiding bad grammar and spelling mistakes as well as unnecessary jargon, circumlocution, and tautology. In particular:•prefer familiar to unfamiliar words,•use a thesaurus to help find the precise word you need,•avoid inelegant, pompous or redundant words,•consider whether terms of legal jargon require definition or explanation,•write properly constructed sentences without undue subordinate clauses,•use a separate paragraph to develop each sub-topic, linking or relating the theme of each paragraph to the previous one and its function in relation to thewhole (a single sentence is unlikely to qualify as a paragraph).3StructureConsider carefully the order in which your material is to be arranged so that your arguments can be put as clearly as possible. No matter how good your ideas are, they depend upon your ability to communicate them. It is often a good idea to use headings and sub-headings to indicate clearly the structure of your answer. The use of defined headings in word-processed documents (described as 'outlining' in MS Word) is an efficient way of structuring and handling text during composition, because it enables you to promote or demote headings and re-arrange material with ease. The advantages of word-processing include the freedom to assemble a document from parts which can be rearranged to suit your theme, and the ability to re-write sections before committing them to print. Take advantage of this. You do not have to start writing the introduction and finish with the conclusion. It may be sensible to postpone writing the introduction until last.QuotationsQuotations must be enclosed in quotation marks ("...") and must have a pinpoint reference (page or, if available, paragraph number). Short quotations can be included naturally in the text, but anything that runs for more than three lines should be separated from the text in an intervening paragraph and indented from the left hand margin. Large numbers of long quotations should be avoided. Make sure you are aware of and comply with the rules against plagiarism. Unattributed quotation is plagiarism.FootnotesYou will need to be able to use word-processed footnotes. There is advice on the correct use of footnotes elsewhere in this document.AbbreviationsYou should use recognised legal abbreviations. Here is a list of common abbreviations.Ibid, loc cit, op cit, and cf.The modern practice is not to use these abbreviated Latin expressions in footnotes at all. Instead simply refer to another footnote by number e.g.:19. See n.12.You are likely to come across these abbreviations in legal writing. Their correct use is as follows:•Ibid (L, ibidem, in the same place)used in successive footnotes when the same authority is referred to repeatedly.4•Loc cit (L, loco citato, in the place cited)used in successive footnotes to refer to a page in a source previously referredto.•Op cit (L, opus citato, in the work cited)used in successive footnotes to refer to a source previously referred to.•Cf (L, confer, compare)used when some meaningful comparison may be drawn, and often misused.Spelling, Grammar and StyleAlthough your work will be marked primarily on its argument and content, spelling, grammar and style are also important factors. Unless you are genuinely dyslexic, bad spelling will be seen as taking less then adequate care. Bad grammar or a poor writing style may divert attention from the points you are trying to make with a consequent loss of marks.Here are some tips.•Do not form plurals with 'apostrophe s',courts = more than one court (i.e. plural)court's = of the or a court (i.e. genitive singular)courts' = of more than one court (i.e. genitive plural)Use "1990s" not "1990's" for the plural form.•Do not confuse singular and plural forms:The Court of Appeal is (not the Court ... are …)Parliament is (not Parliament are …)The Government is (not the Government are …)A committee is ( not a committee are…)A number is (not a number are …)•Do not use "it's" to mean "of it",its = of it,it's = it is or it hasThe best advice is: never use it's, use 'it is' or 'it has' instead.• A sentence needs a verb. End sentences with full stops.•Note the English spelling of "judgment" as applied to courts. In other contexts "judgement" is correct.•"Principal" means the first or highest in rank i.e. "chief"; "principle" is a fundamental proposition.•The modern form of "abolishment" is "abolition".ReviseInclude revision time in your plan. Proof read the entire document, checking for internal consistency, spelling and correct references.Spell CheckersWord processing spelling checkers should be used with caution. They will detect many typographical errors but may offer incorrect or even absurd alternative forms,5and are not a substitute for proof reading, and the use of a dictionary. U.S. spellings are inappropriate in U.K. documents.Citation of sources.Legal writing requires, in various measure, analysis, synthesis, evaluation and criticism of other documentary sources, which may be primary, such as cases and statutes, or secondary, such as books and articles. Suppression of sources can amount to plagiarism which may attract academic and possibly other penalties. The purpose of citation is to enable the reader to identify the writer's sources accurately and unambiguously. There are well-established conventions for the citation of legal materials in U.K. publications, but they differ from social science conventions and also from the practice in the U.S.Selection of sourcesAlways cite the best available source. Cite a primary source for any proposition of law. A primary source is the law itself, stated in legislation or in a binding case. Primary sources are authoritative statements of the law. Secondary sources consist of legal writing, and are never more than persuasive arguments. The authority of secondary sources has to be evaluated. Eminent jurists, especially after death has removed the possibility of any change of mind, are quote-worthy. So too, are authors of peer-reviewed articles in leading journals such as Modern Law Review, Cambridge Law Review, Oxford Journal of Legal Studies, Legal Studies (and for these purposes) Law Quarterly Review. Cite secondary sources for the views of their authors, not for a precis of a primary source.Student text books are not authority for propositions of law, nor are they peer-reviewed, so there will seldom be any occasion to cite them. Similarly, in-house accounts of reported cases on the websites of Solicitors firms are not the 'best available' source of the case.House StyleThe recommended house style for written work in the Law School is the numerical footnote system. Do not use endnotes. If you comply with the house style you cannot be faulted. You will be advised specifically if use of the author-date system is more appropriate.Citation must follow a recognisable existing pattern, uniformly and with internal consistency. Non-conforming citation will lead to deduction of marks. It makes good sense to keep a proper record (i.e. correct title, author, year, volume number, and page reference) of everything you read in preparing every piece of written work, (a) so that you can find it again if need be, and (b) so that you have adequate information for citing that source, should you decide to use it.If in doubt as to the standard form of a particular reference, consult a publication such as, Current Law or Halsbury's Laws of England. Most series of law reports and periodicals actually state their own method of citation.6Numerical system of citationThe principal system of citation of legal material in the UK and the recommended house style for word-processed documents in the Law School is the numerical system of numerically ordered footnotes. This process is automated by modern word-processing software, which you must be able to use. A complete list of all sources should be listed separately in a Bibliography appended to the written work. The Bibliography does not count against the word limit.Numerical system - example.In Khorasandijan v Bush31 the tort of nuisance was utilised to grant the plaintiff an injunction against the defendant who had previously been convicted of threatening and abusive behaviour and subsequently of threatening to kill but who continued to pester her by following her and by phoning her.32Footnotes (in numerical order)31 [1993] QB 727 CA32 Bridgeman J and Jones M, 'Harassing conduct and outrageous acts' (1994) 14 LS 180; Townshend-Smith, R 'Harassment as a Tort in English and American Law' (1995) 24 AALR 299.The BibliographyThe Bibliography should list all sources, both primary and secondary, used in the production of the written work, irrespective of whether they appear in footnotes. You should sub-divide the list into the different classes of materials e.g. Statutes, Statutuory Instruments, Cases, Journals, and Books.The advantage of full referencing in a bibliography (where word limits do not apply) is that, after your first citation of the source in the text, you will be able to truncate your references in the ‘main body’ of text.For example, the full reference to the two journal articles cited in n.32 (above) in the bibliography might read (in alphabetical order):Bridgeman, J. and Jones, M., ‘Harassing conduct and outrageous acts: a cause of action for intentionally inflicted mental distress,’ (1994) 14 Legal Studies 180Townshend-Smith, R 'Harassment as a Tort in English and American Law: the Boundaries of Wilkinson v Downton' (1995) 24 Anglo-American Law Review 299.Once this full reference has been provided (as at n.32), a further reference would merely require:46. Bridgeman and Jones, see n.32.This shortened citation leaves the source no less identifiable and reduces the number of words needed to cite it.7Full citations of case names in the bibliography allow for similar savings in the word count. Consider:24. Butler Machine Tool Co. Ltd. v. Ex-Cell-O Corporation (England) [1979] 1WLR 401With this full reference provided in the bibliography, and fully cited the first time the case is referred to in the main body of your assignment, a subsequent footnote in the main body would merely require:Butler Machine Tool, see n. 24Citation as set out above is compulsory. Wherever references appear in a piece of written work they count against permitted word totals for written work. Word totals take into account the requirement for citation.How to cite legislation.Acts of ParliamentWith very few exceptions, Acts of the UK Parliament have short titles provided by statutory authority:Dangerous Dogs Act 1991, s.10 Short title, interpretation, commencement and extent(1) This Act may be cited as the Dangerous Dogs Act 1991. Although the statute says 'may be cited…' you should treat this as imperative. Short titles have been enacted retrospectively for many older statutes.Short titles used to have a comma between the name of the Act and the year it was passed. The Tangynika Independence Act 1962 was the first to omit the comma, and modern practice is to leave it out, even for Acts passed before the practice changed. It is permissible to abbreviate the short title to initials, e.g. DDA 1991, provided there is no ambiguity.Acts of Parliament are published in their original form by the Queen's Printer who also publishes electronically the full text of the Data Protection Act 1984 and all Acts of Parliament passed since 1st January 1988. These are original versions only; they are not amended to take account of the process of legislative reform. Private publishers' editions of the statutes (e.g. Halsbury's Statutes; Current Law Statutes; CCH Editions; Blackstone's statutes) although not strictly authoritative, are highly reliable and often more convenient than Queen's Printer's copies, because they provide the amended text of the statute.8It will usually be sufficient to refer to the primary sub-division of statutes, namely sections, which in turn may be sub-divided into sub-sections, paragraphs and sub-paragraphs. Other sub-divisions employed include: parts; chapters; and schedules. Schedules contain paragraphs, which may be further subdivided into sub-, subsub, and even subsubsub-paragraphs, and a schedule may be subdivided into parts.To refer to a particular provision in an Act of Parliament use the following method: Companies Act 1985, s.6, orChildren Act 1989, s.15 and sch 1 para 5(n.b. NOT Companies' Act 1985 or Children's Act 1989, unless, of course, the genitive form is used in the short title.It is permissible to refer the "Section 10 of the Children Act 1989…" in the text, but use the shorter form in a footnote.Subordinate UK legislationSubordinate (delegated) legislation is issued in a series called Statutory Instruments (SIs) published on paper from 1894, and electronically from January 1987. They should be cited by their designated title which includes the year they were passed followed by SI year/number in parentheses (e.g. SI 1997/201).The Education (Mandatory Awards) Regulations 1997 (SI 1997/431)The title may be abbreviated to initial letters if to do so would not create ambiguity. Statutory Instruments may be further classified as an 'Order', sub-divided into articles; 'Regulations' sub-divided into regulations; and 'Rules' sub-divided into rules, abbreviated as 'r'.Order Regulations Rulesart arts reg regs r rrThe Civil Procedure Rules 1998 are divided into Parts with numbered Rules corresponding to the Parts. So CPR, Rule 6.4 is in Part 6 paragraph 4. Paragraphs may be sub-divided.Legislation of the European CommunityThe legislation of the European Community consists of the founding treaties, and secondary legislation in the form of Regulations, Directives, Decisions, Recommendations and Opinions. On 1 May 1999 the Treaty of Amsterdam renumbered the original arrangement of Articles of the Treaty of Rome and the Treaty on European Union. To avoid ambiguity the following method of citation is recommended.9On or after 1 May 1999Before 1 May 1999Article or Art 141 EC Article or Art 119 of the EC Treaty The Treaties may be abbreviated as follows:Treaty On or after 1 May1999Before 1 May1999Treaty on European Union EU EU Treaty European (Economic) CommunityTreatyEC EC (EEC) Treaty European Coal and Steel Treaty CS ECSC Treaty Euratom Treaty EA EAEC Treaty Examples of secondary legislation are:Regulation [Council] Regulation No 1111/77/EC, Arts. 8 and 9Directive [Council] Directive 76/207/ECDecision [Commission] Decision 89/58/ECThe full reference will be to the authoritative text in the Official Journal of the European Communities (abbreviated to OJ) where the secondary legislation was first published, together with the title, date and page number:Council Directive of 21 December 1976 on the Coordination of Procedures for the Award of Public Supply Contracts, Directive 77/62/EC OJ L13 15 January 1977 p 1.The OJ is issued in series: L contains legislation, C contains draft legislation.How to cite case law.English casesIntroductionThere are strong conventions governing the citation of case law in the UK, but no formal rules. This document sets out an acceptable practice or house style. Printed law reports (reports of decided cases) are produced by private publishers and since 1865, by a semi-official charitable body known as the Incorporated Council of Law Reporting for England and Wales. The method of citation of these sources is called proprietary citation. Some of these reports are also available from subscription on-line services such as Justis, Westlaw and Lexis Nexis.10In the late 1990s, the advent of digitally prepared judgments, particularly on the World Wide Web, led in January 2001 to the introduction of an additional system of medium neutral citation. This system provides a uniform method of citation independent of printed pages. Cases reported since the introduction of medium neutral citation will conform to the protocol of numbered paragraphs, even though printed on paper.Cases reported before January 2001 sometimes have medium neutral citations applied to them, but these are not authoritative.Proprietary CitationExamples:The Diechland [1990] 1 QB 361.In re Connan: ex parte Hyde 20 QBD 690.Grobbelaar v News Group Newspapers Ltd [2002] 1 WLR 3024.Explanation:Cases are cited by the name(s) of the parties followed by the reference of the publication in which the report of the case appears. Proprietary references do not tell you in which jurisdiction or court the case was heard, and it is good practice to add a suffix to indicate the court e.g. CA for Court of Appeal.Year VolumenumberSeries Page Suffix[1990] 1 QB 361 CA (1888) 20 QBD 690 CA [2002] 1 WLR 3024 HL(E)Notes:•AbbreviationsThe series of the report is always abbreviated. There is a list of commonabbreviations at Appendix I. Consult Current Law or Halsbury's Laws forfuller lists.•Page NumbersProprietary citation refers to printed pages.•Volume numbersAt the time In re Connan was decided (1888), only volume numbers wereused. You should include the year, but it must be in round brackets.•BracketsIn legal citation [ ] and ( ) round the year have special significance. [ ] meansthe year is an essential part of the reference so it must be included and in suchcases the use of [ ] is compulsory. ( ) means the year is not part of thereference. It should be included but it must be in round brackets.•ItalicsIn a word processed document the names of the parties are italicised, andalthough there is a convention that 'v.' is not italicised the house style permitsitalicisation the whole title, including v but not the reference. Underlining is aprinter's mark for italics and may only be used to indicate italics if italic scriptis not available.•PunctuationThe modern practice is not to use punctuation within case references. Inparticular the practice of placing a comma after the names of the parties andbefore the reference is no longer followed.•'Best report'You should follow the practice of the English courts to cite the report of anycase which is reported in the semi-official Law Reports in preference to areport of that case in any other series of reports. Cases reported in volumes 2and 3 of the Weekly Law Reports (WLR) are destined for publication in theLaw Reports, and should be cited only until they are displaced by thesubsequent Law Reports version of that case. Obviously, this practice need not be followed if the purpose of citing the earlier report is to draw attention tosome difference between the two versions.•Electronic versions of printed reportsThe electronic Law Reports from are exact facsimiles of the LawReports, with exactly the same method of citation and can be usedinterchangeably with the printed versions. Westlaw and Lexis Nexis are notexact facsimiles. Even though you may have read the case on Westlaw orLexis Nexis, use the medium neutral citation (if any) and proprietary citationreference to the best series of reports.•Pinpoint referenceIf you wish to refer to some specific point in a report, you should add the pagereference, and if to something said by a judge in the report (L, dictum, pluraldicta) then to the judge's name and page reference:Gillick v West Norfolk and Wisbech Area Health Authority [1986] AC 112 at182 per Lord Scarman.Medium Neutral CitationBy a Practice Note handed down by Lord Woolf CJ on 11 January 2001,all judgments in every division of the High Court and the Court of Appeal will be prepared for delivery, or issued as approved judgments, with single spacing, paragraph numbering (in the margins) but no page numbers.Example:Grobbelaar v. News Group Newspapers Ltd [2001] EWCA Civ 1213.Explanation:Cases are cited by the name(s) of the parties followed by the medium neutral citation. In addition to the year, the reference shows the jurisdiction, the court, the division of that court, the reference number assigned to the case by the official court shorthand writers, and (optionally) a paragraph reference for pinpoint referencing.Medium neutral citation does not use page numbers!Year Jurisdiction Court Division Reference No. Paragraph (if required) [2001] EW CA Civ 1213 [10]In this system EW = England and Wales (Scot = Scotland and NI = Northern Ireland). CA = Court of Appeal and Civ = CivilThe system was extended in 2002. In England and Wales the courts and divisions which are using medium neutral citation are:-Court Division AbbreviationHouse of Lords UKHLCourt of Appeal Civil EWCA CivCourt of Appeal Criminal EWCA CrimHigh Court Chancery EWHC (Ch)High Court Queen's Bench EWHC (QB)High Court Administrative Court EWHC (Admin)High Court Family EWHC (Fam)The Patents Court is EWHC (Pat), the Commercial Court EWHC (Comm), the High Court Admiralty Court is EWHC (Admlty), and the High Court Technology & Construction Court is EWHC (TCC).•Pinpoint ReferencesIf a case has a medium neutral citation you may use that alone, or you mayadd a reference to the best printed version of the case e.g. Grobbelaar v News Group Newspapers Ltd [2002] UKHL 40, [2002] 1 WLR 3024. A pinpointreference to a pre-medium neutral case will be to page number and side letter(if there is one). If the report has numbered paragraphs, then even in the caseof a printed report, the pinpoint reference should always be to the paragraphnumber (shown in [ ]).Medium Neutral Citation in the House of LordsThe Appellate Committee of the House of Lords was not bound by Lord Woolf CJ's Practice Note of 11 January 2001. On 18 January the House adopted its own slightly different version of medium neutral citation:Manifest Shipping Company Limited v. Uni-Polaris Shipping Company Limited, [2001] UKHL/1is the first case in the UK House of Lords in 2001. The neutral citation UKHL does not indicate the jurisdiction (England and Wales, Scotland, or Northern Ireland) from which the appeal arose. The 13th case on 22 March began omitting the / before the number of the case:Johnson (A.P.) v. Unisys Ltd [2001] UKHL 13。

BTBU_4.2 Audit Partner Specialization and Audit Fees_ Some Evidence from Sweden

Audit Partner Specialization and Audit Fees:Some Evidencefrom Sweden*MIKKO ZERNI,University of Vaasa1.IntroductionThe purpose of this study is to examine auditor specialization and pricing at the individual partner level.1In the aftermath of major accounting scandals such as ComROAD AG, Enron,Parmalat,Tyco,Waste Management,and WorldCom,regulators and investment communities have been seeking to restore investor conﬁdence in the capital markets.The response worldwide has been increases in regulation,and in these reforms accounting and auditing have been identiﬁed as priority areas to‘‘ﬁx’’.For instance,with the aim of increasing audit market transparency,the amended European Union’s(EU’s)8th Directive requires the disclosure of engagement partner identity.2Currently,the Public Company Accounting Oversight Board(PCAOB)in the United States is considering a similar requirement.On October6,2008,the U.S.Treasury’s Advisory Committee on the Audit-ing Profession(ACAP)issued itsﬁnal report,which recommends,among other things,‘‘urging the PCAOB to undertake a standard-setting initiative to consider mandating the engagement partner’s signature on the auditor’s report’’(ACAP Report,October6,2008, at VII:19).3According to the ACAP’s recommendation,the requirement for the engage-ment partner to sign the audit report could improve audit quality in two ways:‘‘First,it might increase the engagement partner’s sense of accountability toﬁnancial statement *Accepted by Ferdinand A.Gul.An earlier draft of this paper was entitled‘‘Audit Partner Specialization, Audit Fees,and Auditor-Client Alignments’’.I appreciate the comments received from Ferdinand A.Gul (the associate editor),two anonymous reviewers,Pekka Alatalo(KPMG Finland),Jean C.Bedard(discus-sant),Andy Conlin,Ann Gaeremynck,Kaarina Halonen(PWC Finland),Seppo Ika heimo,Henry Jarva, Juha Joenva a ra,Juha-Pekka Kallunki,Eija Kangas(KPMG Finland),Robert Knechel,Anna-Maija Lantto, Christophe Van Linden,Lasse Niemi,Henrik Nilsson,Mervi Niskanen,Jukka Perttunen,Peter Pope, Markku Rahiala,Veijo Riistama(PWC Finland),Petri Sahlstro m,Stefan Sundgren,Risto Tuppurainen, Soﬁe Vandenbogaerde,Ann Vanstraelen,Markku Vieru,Marleen Willekens,and Erik A stro m(Ernst& Young Sweden).I would also like to thank the participants at the24th Contemporary Accounting Research Conference in Montreal Canada(2009),AFI seminar at Katholieke Universiteit Leuven(2011)and the AFAR workshop in Vaasa(2008)for their comments.I wish to thank Tuomas Anttila,Marja Kauppinen, and Harri Lempola for their excellent research assistance.Financial support received from the NASDAQ OMX Nordic Foundation,the Finnish Foundation for the Advancement of Securities Markets,the Founda-tion for Economic Education,the Ostrobothnia Cultural Foundation,and the Finnish Cultural Foundation is gratefully acknowledged.This research is part of research projects by the Academy of Finland(Grant Numbers140000and126630).All remaining errors are mine alone.1.The terms‘‘auditor specialization’’and‘‘auditor expertise’’,as well as the terms‘‘engagement partner’’,‘‘auditor’’,and‘‘audit partner in charge’’are used interchangeably in this study.2.The new EU directive obligesﬁrms to disclose the identities of individual auditor(s)responsible for theengagement.Speciﬁcally,Article28of the directive2006⁄43⁄EC states:‘‘Where an auditﬁrm carries out the statutory audit,the audit report shall be signed by at least the statutory auditor(s)carrying out the statutory audit on behalf of the auditﬁrm.’’3.The comment period on the concept release ended on September11,2009,and according to the PCAOB’sOfﬁce of the Chief Auditor’s standard-setting agenda,‘‘the Board’s consideration of next steps is pending further action’’(PCAOB,October2010,p.7).Available at:/News/Events/Documents/ 10132010_SAGMeeting/OCA_standards-setting_agenda.pdf.Contemporary Accounting Research Vol.29No.1(Spring2012)pp.312–340ÓCAAAdoi:10.1111/j.1911-3846.2011.01098.xAudit Partner Specialization and Audit Fees313 users,which could lead him or her to exercise greater care in performing the audit. Second,it would increase transparency about who is responsible for performing the audit, which could provide useful information to investors and,in turn,provide an additional incentive toﬁrms to improve the quality of all of their engagement partners.’’Some have compared the initiative to theﬁnancial statement certiﬁcation requirement by top manage-ment stipulated in Section302of the Sarbanes-Oxley Act,arguing that it should help focus engagement partners on their existing responsibilities(see,e.g.,Carcello,Bedard, and Hermanson2009:79).4Changes in legislation and initiatives requiring the disclosure of the identities of individ-ual auditors carrying out audits implicitly acknowledge that a public company audit involves a substantial amount of work by highly skilled individual practitioners exercising their own professional judgment.It is the lead engagement partners working in the city level audit ofﬁces who play a central role in planning and implementing the audit and ulti-mately in determining the appropriate type of audit report to be issued to the client(e.g., Ferguson,Francis,and Stokes2003).Consequently,the engagement partner may play an essential role in the(perceived)audit quality beyond auditﬁrm size and(industry)special-ization at the national and ofﬁce level and should hence not be ignored.The level of audit effort and fees depends on the client’s agency-driven demand for external auditing and on supply-side factors,such as auditﬁrm size,auditor expertise and auditor-perceived risk factors(e.g.,DeFond1992;O’Keefe,Simunic,and Stein1994; Gul and Tsui1998;Bell,Landsman,and Shackelford2001;Johnstone and Bedard2001, 2003;Gul and Goodwin2010;Causholli,De Martinis,Hay,and Knechel2011).From the supply-side perspective,auditors are expected to respond to the higher probability of any irregularities or accounting misstatements by increasing audit effort and charging higher fees.For instance,Gul and Tsui(1998)adopted a supply-side perspective and found that higher inherent risks associated with free cashﬂows are associated with higher audit effort and higher consequent fees.From the demand-side perspective,the appointment of a higher-quality auditor can serve as a signal of an enhanced quality of ﬁnancial disclosure,which will potentially lead to greater value for the audit client by reducing some agency costs.Firm insiders,especially those in the heart of monitoring function(e.g.,independent directors on the boards and audit committees),may be willing to increase audit coverage to create a positive perception about theﬁnancial reporting quality.The positive perception will possibly facilitate theﬁrm to attract investments and fund proﬁtable projects and allowﬁrm insiders to protect their reputation capital,avoid legal liability,and promote shareholder interests.Consistent with the demand-side per-spective,several studies report evidence suggesting that outside directors who act dili-gently demand high quality audits and pay higher audit fees(e.g.,Carcello,Hermansson, Neal,and Riley2002;Abbott,Parker,Peters,and Raghunandan2003;Knechel and Willekens2006).Auditing is generally viewed as a differentiated service with substantial variation observed in audit(effort)fees,even after controlling for observable factors such asﬁrm size and complexity.This differentiation allows clients some choice over the level of audit scrutiny even within audits conducted by the same(tier)auditﬁrms.An important means 4.Recent empirical evidence supports the view that the Sarbanes-Oxley Act Section302chief executive ofﬁ-cer(CEO)and chiefﬁnancial ofﬁcer(CFO)certiﬁcation requirement had a positive effect onﬁnancial reporting quality.For instance,Cohen,Krishnamoorthy,and Wright(2010)report that68percent of practicing auditors interviewed believe that the certiﬁcation requirement has had a positive effect on the integrity ofﬁnancial reports.Moreover,to the extent that the disclosure of engagement partner identity will increase accountability,it may thereby improve audit decisions and judgments.In particular,some studies in the auditing context report evidence indicating that accountability reduces information process-ing biases,and increases consensus and self-insight(e.g.,Johnson and Kaplan1991;Kennedy1993).CAR Vol.29No.1(Spring2012)314Contemporary Accounting Researchof audit product differentiation is through investments in specialization(Simunic and Stein1987;Liu and Simunic2005).By specializing in certain industries,certain size groups,or companies with similar risk proﬁles,individual auditors may be able to differ-entiate their product from those of nonspecialist audit partners(Simunic and Stein1987; Liu and Simunic2005).The Swedish Code for Corporate Governance,for instance, implicitly recognizes auditor specialization in large public companies as one relevant piece of information when assessing the quality of external auditing.5Speciﬁcally,the Code rec-ommends that information on‘‘the audit services performed by the auditor or the auditor in charge in other large companies...and other information that may be important to shareholders in assessing the competence and independence of the auditor,or auditor in charge must be disclosed in a corporate governance report on company’s homepage’’(Ori-ginal Code Sections2.3.2and2.3.3).To justify their presence in the audit market and the potential fee premiums attached to their services,the client must perceive some beneﬁt in hiring a specialist auditor.The premium may,for instance,be attributed to the signal value of hiring a specialist auditor or to the superior advisory or other services provided by that auditor(Titman and Trueman1986).Given that a demand exists for special-ist auditors,that demand gives those auditors a greater‘‘power’’in pricing relative to nonspecialists.This paper is motivated by the lack of archival research examining issues related to engagement partner specialization.In the present study,the use of Swedish data makes it possible to construct individual audit partner client portfolios because each audit report discloses the name of the audit engagement partner.Thus,information on the identity of the audit partner in charge is observable to users ofﬁnancial statements and thereby potentially affects market-assessed perception of ex ante audit rma-tion on the sizes and compositions of the Big4audit partner-speciﬁc client portfolios provides an interesting opportunity to contribute to a more thorough understanding of auditor specialization.More speciﬁcally,it is possible to examine whether the perceived audit quality is affected not only by the brand name of theﬁrm,but also by the charac-teristics and reputation of the engagement partner.In essence,if auditing expertise were wholly transferable and therefore uniformly distributed across audit partners within the ﬁrm,any clientﬁrm would be indifferent to having any audit partner within the Big4 auditors(within a particular Big4auditﬁrm⁄ofﬁce)to conduct the audit.Additionally, there would be no a priori reason why clients would be willing to pay any audit partner related premiums.The empiricalﬁndings indicate systematic differences between audit partner clienteles, suggesting audit partner specialization in different industries and in different size groups. Thisﬁnding is consistent with Liu and Simunic2005,who argue that auditor specializa-tion could be a competitive response by either an auditﬁrm or an individual audit part-ner to induce efﬁcient audits for different types of clients,thereby gaining a limited monopoly power(and earning rents)over the clients in which they specialize.Further-more,consistent with the view that there are returns on investing in specialization,analy-ses of audit fees indicate that both audit partner industry specialization and specialization in large public companies are recognized and valued byﬁnancial statement users and⁄or by corporate insiders,resulting in higher fees within these engagements.According to the empirical analyses,the highest fees are earned by engagement partners who are both 5.The Swedish Corporate Governance Board is responsible for promoting and developing the Code.On July1,2005,the Stockholm Stock Exchange began applying the Swedish Code of Corporate Governance.The Code applies to all Swedish companies listed at the Stockholm Stock Exchange and foreign companies that are listed at the same exchange and whose market capitalization exceeds SEK3billion.For more information,see

appointment of a specialist engagement partner is associated with higher(perceived)audit quality,thus justifying the fee premium.6Collectively,theﬁndings of this study support the view that clientﬁrms infer audit quality at least to some extent from the characteris-tics of the individual audit partner in charge.The remainder of the paper is organized as follows.Section2reviews the relevant lit-erature and describes some relevant features of the Swedish audit market.Section3pre-sents the hypothesis,and section4describes the data.Section5describes the methodology used,section6presents the empirical results,and section7concludes the study.2.Literature reviewNational versus local view of the auditor–client relationshipPrior audit research literature is dominated byﬁrm-wide analyses treating the whole accountingﬁrm as the focal point and investigating whether and how auditﬁrm char-acteristics,such as size and industry specialization at the nationalﬁrm level,affect the auditor–client relationship(e.g.,Simunic and Stein1987;Francis and Wilson1988;Bec-ker,DeFond,Jiambalvo,and Subramanyam1998;Francis and Krishnan1999).All these studies implicitly assume that through standardizedﬁrm-wide policies and knowl-edge sharing(e.g.,through training materials,industry-speciﬁc databases,internal benchmarks for best practices,audit system programs,and internal consultative prac-tices),all audits across practice ofﬁces and audit partners within an auditﬁrm are uniform.7However,in practice,it is the individual audit partners from city-level practice ofﬁces who are creating and taking care of the relationship,contracting with the client,adminis-tering the audit engagement,directing the audit effort,interpreting the audit evidence,and ﬁnally issuing the appropriate audit report(Ferguson et al.2003).Because of this decen-tralized organizational structure and because individual audit partners and their character-istics vary across engagements,a research approach allowing each individual partner to be a unique and relevant unit of analysis might be a more reasonable approach than assum-ing that all audits within an auditﬁrm are uniform.Consistent with this intuition,a growing number of recent audit studies have changed the direction from aﬁrm-wide to an ofﬁce-level view of auditﬁrms(e.g.,Reynolds and Francis2000;Ferguson et al.2003;Francis,Reichelt,and Wang2005;Francis and Yu 2009;Reichelt and Wang2010;Choi,Kim,Kim,and Zang,2010).The local stream of audit literature acknowledges the likelihood that part of an auditor’s expertise is uniquely held by individual professionals through their personal knowledge of clients and cannot be 6.From the risk-based audit supply view,an alternative explanation for the observed specialist audit partnerfee premium is that the clients of specialist audit partners are systematically riskier than the clients of non-specialists in dimensions other than those already controlled for in the empirical fee model(or in theﬁrst-stage selection model of the Heckman two-stage approach).Despite using a two-stage Heckman1978pro-cedure and including several audit risk-related control variables in the audit fee model,the empiricalﬁnd-ings remain susceptible to the concern that some of the omitted risk factors recognized and priced by the specialist audit partners that simultaneously determine the alignment of audit partners with engagements would explain the outcome.7.Examples of the information technology systems used in knowledge sharing include KPMG’s KWorld TM,PriceWaterhouseCoopers’s TeamAsset TM and KnowledgeCurve TM,and Ernst&Young’s Knowledge-Web TM.See Vera-Munoz,Ho,and Chow2006for factors affecting knowledge sharing within interna-tional accountingﬁrms,and Banker,Chang,and Kao2002for a detailed description of an international accountingﬁrm’s implementation of audit software and groupware for knowledge sharing.CAR Vol.29No.1(Spring2012)316Contemporary Accounting Researchreadily captured and distributed by theﬁrm to other ofﬁces and clients(e.g.,Ferguson et al.2003).8The results of the empirical studies adopting a local perspective tend to provide a bet-ter understanding of the operations of a Big4auditﬁrm than do studies taking a national perspective.For instance,there is evidence that auditors’reputation for industry expertise is neither strictly national nor strictly local in character.Auditors who are both city and industry leaders are reported to earn fee premiums both in Australia and in the United States,suggesting that there is both a national and local ofﬁce reputation effect in the pric-ing of industry expertise(Ferguson et al.2003;Francis et al.2005).Moreover,both these studiesﬁnd thatﬁrm-level industry specialists alone do not earn statistically signiﬁcant premiums.In another study,Reichelt and Wang(2010)use U.S.data and three proxies for audit quality(abnormal accruals,clientﬁrms’likelihood of meeting or beating ana-lysts’earnings forecasts by one penny per share,and the propensity to issue a going con-cern audit opinion)andﬁnd evidence consistent with the view that audit quality is higher when the auditor is both a national and city-speciﬁc industry expert.Recent and concurrent studies have pushed the local analysis still one step further to the engagement partner level.A growing number of studies use engagement partner data (mainly from Australia and Taiwan)and examine issues such as the relationship between engagement partner tenure and audit quality,producing mixedﬁndings(e.g.,Carey and Simnett2006;Chen,Lin,and Lin2008;Chi,Huang,Liao,and Xie2009).In a recent study,Chin and Chi(2009)use a sample of listedﬁrms in Taiwan to investigate the associ-ation between auditor industry expertise and restatement likelihood at the partner level and at the auditﬁrm level simultaneously.Their evidence suggests that the differences in restatement likelihood due to industry expertise is mainly attributable to the partner-level experts rather than to theﬁrm-level experts.In summary,the recent empirical evidence suggests that auditor expertise has a strong local dimension.The central conceptual question in all the national versus local studies relates to the degree to which there is a transfer of expertise from ofﬁce-based accounting professionals to other auditors and ofﬁces within theﬁrm(Ferguson et al.2003;Francis2004).There are several factors that may deter the transfer of expertise within organizations,including audit ﬁrms(see,e.g.,Szulanski1994,2000;Nonaka and Takeuchi1995).With respect to audit ﬁrms,Vera-Munoz et al.(2006)enumerate several reasons why it is difﬁcult for partners to share knowledge with other partners.First,a considerable amount of knowledge in audit ﬁrms can be difﬁcult to document or transfer.9Second,even if an auditﬁrm manages to 8.As noted by Francis2004,another reason for this development is that Big4market shares continue toexpand globally,leading to low power in research designs of studies comparing large and small auditors because there is such low variance in the experimental variable(i.e.,most observations are audited by large Big4auditors).For instance,according to a recent Government Accountability Ofﬁce(GAO) report,in2006the largest fourﬁrms collected94percent of all audit fees paid by public companies.More-over,according to the same report,82percent of the Fortune1000companies saw their choice of auditors as limited to three or fewerﬁrms,and about60percent viewed competition in their audit market as insuf-ﬁcient(GAO2008).9.According to Polanyi1966,knowledge comes in two types:explicit and tacit.The former is amenable tocodiﬁcation,while the latter is anchored in individual personal beliefs,experiences,and values.For exam-ple,knowledge of generally accepted accounting principles(GAAP)with regard to fair value requirements is explicit knowledge,while an auditor’s insights as to how a client’s management develops fair value esti-mates and whether those estimates conform to GAAP represents tacit knowledge(Vera-Munoz et al.2006).Tacit knowledge is subconsciously understood and applied and is therefore not easily articulated (Polanyi1966).Prior studies further show that most of the knowledge in any organization,including an auditﬁrm,is tacit knowledge(Bonner2000;Knechel2000).Consequently,because differences in knowl-edge between individual auditors within aﬁrm lie primarily in their respective tacit knowledge,which is not easily transferred,it is unlikely thatﬁrm-level practices completely smooth out the differences in the levels of individual audit partner expertise.CAR Vol.29No.1(Spring2012)Audit Partner Specialization and Audit Fees317 collect extensive databases and otherﬁrm-wide knowledge,individual auditors still need to use their own judgment in selecting and applying relevant pieces of information given the task at hand.Third,knowledge-sharing through information technology–based expert knowledge systems is not automatically embraced by everyone.Finally,evaluation appre-hension,performance-based compensation schemes and individual auditors’pursuit of per-sonal beneﬁts and power may deter auditors from sharing what they know.In essence, holding on to information that other peers do not have may ceteris paribus offer competi-tive advantage against those peers,when auditors,like other rational players in the econ-omy,attempt to maximize their own(economic)interests.Collectively,factors identiﬁed above may partly explain the tendency of local audit studies to provide a better understand-ing of the auditor-client relationship thanﬁrm-wide analyses.Factors affecting expertiseThe Merriam-Webster dictionary deﬁnes an‘‘expert’’as having,involving,or displaying a special skill or knowledge derived from training or experience.The psychological literature on expertise has reported two importantﬁndings relevant to the present study.First, domain-speciﬁc knowledge is the essential determinant of expertise.Second,expert knowl-edge is gained through many years of on-the-job experience(e.g.,Chi,Glaser,and Rees 1982;Glaser and Chi1988;Glaser and Bassok1989;Lapre,Mukkerjee,and Van Was-senhove2000).In other words,intensive practice and the repetition of similar tasks are required to build expertise.When applied to auditing,theseﬁndings suggest that having serviced many similar clients in the past may help auditors to develop a specialized knowl-edge of what these clients do and the challenges and issues they face,thereby creating in-depth knowledge of speciﬁc types of clients,leading to higher-quality audits and higher fees in these engagements.Consequently,in the present study,the terms‘‘auditor special-ization’’and‘‘auditor expertise’’are used to refer to the extent of auditors’prior audit experience with similar clients,for instance,clientﬁrms belonging to the same industry or size group.In other words,it is assumed that specialization is needed to gain deep exper-tise.By specializing in certain industries,certain size groups,or companies with similar risk proﬁles,individual auditors may be able to develop and supply the differentiated ser-vice that clients demand and that competitorsﬁnd difﬁcult to duplicate(Simunic and Stein 1987;Liu and Simunic2005).Moreover,auditors will only develop a specialist reputation if this increases the credibility ofﬁnancial reporting and attracts clients.Auditor specialization and audit qualityFor a long time,standard-setters,quasi-regulatory bodies,and empirical audit research have suggested that differences in the level of auditor industry expertise may be one source of variation in audit quality(Hogan and Jeter1999;Gramling and Stone2001;GAO 2008).This body of literature assumes that audit issues are nested within an industry and that accountingﬁrms or individual auditors with many clients within a particular industry have more opportunities to acquire the kind of profound industry knowledge that leads to industry expertise.It is also argued that the heavy investments of industry specialist audi-tors in technologies,physical facilities,personnel,and organizational control systems pro-vide them with both incentives and abilities that make them more likely than nonspecialist auditors to detect and report any irregularities or misrepresentations in clientﬁrms’accounts(Simunic and Stein1987).Prior archival studies tend to document a positive association between auditors’indus-try expertise and the quality ofﬁnancial reporting(e.g.,Carcello and Nagy2002,2004; Balsam,Krishnan,and Yang2003;Krishnan2003,2005;Gul,Fung,and Jaggi2009).Spe-ciﬁcally,industry specialist auditors have been found to be less likely to be associated with Securities and Exchange Commission enforcement actions(Carcello and Nagy,2004).CAR Vol.29No.1(Spring2012)318Contemporary Accounting ResearchTheir clients are also reported to have a lower probability ofﬁnancial fraud(Carcello and Nagy2004,2004),smaller amounts of abnormal accruals,and higher earnings response coefﬁcients(Balsam et al.2003;Krishnan2003,2005).In addition,a recent study by Gul et al.2009reports evidence suggesting that auditor industry specialization is likely to reduce the association between shorter auditor tenure and lower earnings quality.Behavioral research using experimental approaches has examined industry specializa-tion at the individual auditor level.The results of these studies suggest that an individual auditor’s expertise is tied not only to each individual professional and his or her deep per-sonal knowledge of clients but also to the innate abilities of each individual(e.g.,Bonner and Lewis1990;Libby and Tan1994;Owhoso,Messier,and Lynch2002).Overall,the results of studies on auditor specialization suggest that industry specialist auditors deliver higher-quality audits than do nonspecialists and that this difference in quality is also rec-ognized by the audit market.Even though the auditor specialization literature has focused almost entirely on indus-try specialization,it is plausible that there are also other types of auditor specialization besides industry specialization.Accordingly,an investigation of the(Swedish)homepages of the Big4ﬁrms reveals that each of theﬁrms has structured their national practices along both industry lines and client size.All have at least two business lines based on client size:small and medium-sized companies and large public⁄international companies. All fourﬁrms also market a wider variety of specialized expertise,such as specialization in owner-manager companies,family businesses,public sector organizations,and nonproﬁt organizations.Moreover,as noted already,the Swedish Code for Corporate Governance implicitly recognizes auditor specialization in working with different size groups by recom-mending the disclosure of‘‘the audit services performed by the auditor or the auditor in charge in other large companies’’,viewing this as a relevant piece of information for users ofﬁnancial statements.Performing audits of large,complex high-proﬁle clients is likely to require auditor expertise widely different from that required for audits of smaller and simpler closely held clients.A public listing is an important part of auditor business risk(Johnstone and Bedard2003).Because companies listed on a stock exchange receive more media attention and therefore pose a higher litigation and reputational risk,they may require a specialist auditor(Johnstone and Bedard2003).Another clear distinction between audits of public and private companies relate toﬁnancial reporting standards.10In Swe-den,as in all EU member countries,publicly listed companies are required to follow IFRS standards in theirﬁnancial reporting.Whereas Swedish private companies are also allowed to follow IFRS standards in their consolidatedﬁnancial statements,they tend to follow national standards(Bokfo ringsna mndens Anvisningar),which include several signiﬁcant simpliﬁcations compared to IFRS.Accordingly,in the present study,com-pany size and listing status in particular is used as a proxy for client complexity and risk proﬁle.The aforementioned differences between audits of public and private companies make it more likely that client companies will value auditor specialization in particular size groups(i.e.,public versus privateﬁrms).They may also suggest that specialization in a certain size group will overlap somewhat with industry specialization.It appears intuitively more valuable for publicly listed client companies seeking a higher level of audit assurance to hire an engagement partner with relevant industry experience on other large companies with similarﬁnancial reporting requirements,rather than hire an engagement partner with industry experience only on smaller private companies.This potential overlap is further addressed in the empirical results section below.10.I wish to thank an anonymous reviewer for making this point.CAR Vol.29No.1(Spring2012)。

2012年英语2text4英文回答：The Impact of Technology on Communication: A Double-Edged Sword.Technology has profoundly reshaped the way we communicate, offering unprecedented opportunities for connection and information exchange. However, this technological revolution has also brought about a range of challenges that necessitate a critical examination of its impact on communication.Positive Impacts.Increased Accessibility and Convenience: Technology has made communication more accessible and convenient than ever before. With smartphones, social media platforms, and video conferencing tools, we can connect with people across vast distances in real-time. This has facilitated globalcollaboration, fostered relationships, and enabled individuals to stay in touch with loved ones who live far away.Enhanced Efficiency and Speed: Technological advancements have significantly increased the speed and efficiency of communication. Email, instant messaging, and social media allow us to send and receive messages instantly, eliminating the delays associated withtraditional mail or phone calls. This has streamlined business processes, improved productivity, and enabled us to respond to inquiries and resolve issues more quickly.Access to Information and Knowledge: The internet has become an invaluable source of information and knowledge. Search engines, online libraries, and educational platforms provide access to a vast repository of knowledge that can inform our decisions, expand our perspectives, and enhance our learning. This has fostered a culture of continuous learning and empowered individuals to become more informed and enlightened.Negative Impacts.Reduced Face-to-Face Interaction: While technology has increased our connectedness, it has also diminished the frequency and quality of face-to-face interactions. The convenience of virtual communication may lead people to withdraw from in-person conversations, resulting in a loss of non-verbal cues and the personal touch that is essential for building strong relationships.Increased Social Isolation: Excessive use of social media and technology can contribute to social isolation, particularly among vulnerable individuals. The constant comparison of oneself to others on social media platforms can foster negative body image, anxiety, and feelings of inadequacy. Additionally, the tendency to interact with others primarily through virtual channels may lead to a decline in real-world social skills and a diminished sense of belonging.Spread of Misinformation: The internet and social media have enabled the rapid spread of information, bothaccurate and inaccurate. This poses a significant challenge, as it becomes increasingly difficult to discern the truth from falsehoods. Misinformation can shape public opinion, influence decision-making, and even incite violence.Conclusion.Technology has had a profound impact on communication, offering both benefits and drawbacks. While it has enhanced accessibility, convenience, and information exchange, ithas also diminished face-to-face interaction, fosteredsocial isolation, and contributed to the spread of misinformation. As technology continues to evolve, it is essential to approach its use with a critical mindset, recognizing its potential for both good and harm. We must strive to harness its benefits while mitigating itsnegative consequences, ensuring that communication technology serves as a tool for progress and human connection.中文回答：科技对交流的影响，一把双刃剑。
