1. Problem formulation —which topic or field is being examined and what are its component issues? 2. Literature search —finding materials relevant to the subject being explored 3. Data evaluation —determining which literature makes a significant contribution to the understanding of the topic 4. Analysis and interpretation —discussing the findings and conclusions of pertinent literature
学术英语理工综述范文
学术英语理工综述范文English:In recent years, academic research in the field of science and technology has been increasingly focused on the integration of interdisciplinary knowledge and the application of advanced technologies. This trend has led to the emergence of a new genre of academic writing known as the engineering and technology literature review. This type of literature review aims to provide a comprehensive and critical analysis of existing research and developments in a specific area of engineering or technology. To achieve this, authors typically draw on a wide range of sources, including academic journals, conference proceedings, and technical reports. By synthesizing and evaluating these sources, authors are able to identify key trends, gaps, and challenges in the field, and propose new directions for future research. Furthermore, the use of advanced technologies such as data mining and machine learning has enabled researchers to conduct more comprehensive and systematic literature reviews, leading to a deeper understanding of complex engineering and technological issues. Overall, the academic English used in engineering and technology literature reviews plays acrucial role in disseminating valuable knowledge and insights to a global audience of researchers and practitioners.Translated content:近年来，科技领域的学术研究越来越关注跨学科知识的整合和先进技术的应用。

motivates human behavior.
These themes are: incorporation of the self-concept into traditional theories of motivation, the influence of rewards on motivation, the increasing importance of internal forces of motivation, autonomy and selfcontrol as sources ofmotivation, and narcissism as an essential component of motivation. Although the literature represents these themes in a variety of contexts, this paper will primarily focus on their application to self-motivation.
什么是LiteratureReview（文献综述）？快到ddl你还懵？
什么是LiteratureReview（文献综述）？快到ddl你还懵？不知不觉，八月已经过了快一半了，还有不到一个月就要交dissertation，也就是毕业论文了。
在阅读了大量文献和确定研究方法主题后，作为dissertation的第一个大模块，很多小伙伴都在开始撰写Literature Review了。
最近，君君收到很多来自毕业生的消息，咨询如何写Literature Review，并觉得特别头疼这一部分。
今天，让我们一步一步剖析什么是LR怎么写好LR吧！首先，我们要明确什么是LR。
什么是LR01毕业论文作为学术性作文，LR部分需要向读者提供有关你主题的重要文献的分析性概述。
如果你的受众比你对该主题的了解少，那么你的目的就是教学。
当然啦，绝大多数同学做的研究项目属于这一种：如果受众（导师）比你更了解这个话题，那么你的目的是展示对该主题的熟悉程度，专业知识的贮备和智能。
# 将一个人的原创作品放在现有文献的背景下。
# 解释与您的主题相关的主要问题。
# 描述每项工作与正在考虑的其他工作的关系。
# 找出解释的新方法，并阐明以往研究中的任何差距。
# 解决之前看似矛盾的研究中的冲突。
# 确定哪些文献对理解您的主题做出了重要贡献。
# 指出进一步研究你的主题的方法。
LR要写什么？02简单来说，我们要牢牢记住一个词“结构合理well structured”你的想法必须在逻辑上从一个点流向另一个点，或是从一个点拓展散射开到几个相对于的研究问题上。
内容上我们主要有四大项必须满足概念：利用文献概述你正在考虑的主题，问题或理论。
归类：将你收集到的这些文献划分类别和概念，也就是按照Research Question归类关联：将前人的工作与你的工作，你想法之前的作品和你的研究点联系起来。
评估：对那些对理解和发展主题做出最大贡献的作品提供结论。
在写这四大部分的过程中，每当你计划将文献纳入你LR的过程中，先思考这几个问题：资格:这篇文章作者有什么资格来做出判断?中立:作者的观点是公正的还是有偏见的?可信度:作者的哪篇论文哪个观点令人信服，为什么?价值:作者的结论是否增加了你研究的问题的价值?看到这里，已经成功了一半啦！加油继续哦！内容上我们主要有四大项必须满足概念：利用文献概述你正在考虑的主题，问题或理论。

Literature Revieentioned above, short-run event study can be applied in the empirical test for EMH. On the other hand, event studies using long horizon (1-5 years post acquisition) data can be applied to evaluate the effect of M A event on long-term stock market performance of firms. This closely relates to the famous “post-merger underperformance puzzle”proposed in Agrap; Jaffe (2000). In that article, they documented the conclusions made by various researchers on the long-run underperformance of acquiring firms in the stock market. Hopirical methods used by various authors in examining the long-run performance. The first difficulty encountered in long-run event studies is the calculation of expected returns. Different choices of benchmark models could lead to exactly opposite conclusions, since small measurement errors accumulate in the long-run (Kothari and itchell and Stafford(2000) also shoes higher than the appropriate t-statistics. Fama (1998) advocates the use of calendar time portfolio in correcting for cross-sectional correlation problem. On the other hand, Barber and Lyon (1997) proves that the use of reference portfolio or asset pricing model in calculation of abnormal returns suffers three types of biases in long-run study. The proposed solution is to match sample firms to non-sample parable firms of similar market capitalization and market-to-book ratios. The usefulness of another benchmark model -- the Fama- French three-factor model –seems to be less efficient than the previous tethods (Barber and Lyon 1997, Brav 2000).Another difficulty arises from houlate abnormal returns over time. It is mon to use cumulated abnormal returns (CAR) for short-run study, but Barber and Lyon (1997) argues that this measure is conceptually flaeasure ore sensible based on conceptual grounds is the buy-and-hold abnormal returns (BHAR) etric sums of abnormal returns rather than arithmetic sums as in CAR. Ho simulation shoal returns more often. To correct f-->or such bias, Lyon, Barber and Tsai (1999) proposes the bootstrappedskepirical study in the current paper is focused on short-run period around the event date. Tine the significance of abnormal returns. The first one is to test ent of M A on share performance is significant or not, ation content of MA announcement. This is done by testing for the significance of abnormal returns on single days. The second one is to test for the significance of the event over a short period. This closely relates to the leakage of information ahead of such events and the question of hoarket responds to such events. This is done by testing for the significance of cumulative abnormal returns for a short interval. Since ance of all the sample panies, the individual abnormal return during the event period is averaged across 91 firms, as ulative abnormal return.Define t as the day measured in event time. The date that each acquiring firm announces its merger/acquisition corresponds to t = 0. For each firm, closing share price and contemporaneous FTSE All share index data from t = -100 (100 trading days before the firm’s merger announcement) until t = +5 (5 days after the announcement) are collected. Let and denote the simple daily return for security i and market index at day t, respectively. In the current paper, the estimation period runs from t = -100 to t = -10, and the event period runs from t = -5 to t = +5.The first step is to measure abnormal return, denoted by , for firm i at day t in the event period. Ordinary least squares (OLS) is applied to estimate the market model for firm i, that is, OLS is used to estimate alpha () and beta () parameters for each firm using daily returns from the estimation period, and the abnormal return for each day in the event period is calculated using the folloal return is often affected by firm-specific characteristics, the abnormal returns from equation (1) are averaged for analysis based on the ple of firms. For a given day t in the event period, let denote the average daily abnormal return over all the sample firms, and denote the cumulative average daily abnormal return from the first day in event period (-5) till day t. Similarly, the cumulative daily abnormal return for a specific firm i, denoted by , can be defined. Therefore,Folloal return is then normalized by the sample standard deviation for the daily return--> of corresponding security, denoted by , to yield a standardized abnormal return, (See also Serra 2002):Averaging it over all sample firms, the average standardized abnormal return for day t, denoted by , can be calculated. The test statistic for a given day in the event period (-5 through +5) is as follople size of firms, the central limit theorem that under the independent and identically distributed condition, the statistic in equation (6) should be standard normally distributed asymptotically. The null hypothesis for the first testis that the average standardized abnormal return for day t is 0, i.e. =0. The hypothesis test can also be constructed concerning a period of time. Let , (-530). The null hypothesis for the second test is that the cumulative average abnormal return during the period [,] is 0, i.e. =0.。

Unit 4 Writing a Literature ReviewI. Teaching ObjectivesIn this unit, you will learn how to:1.write a self-contained literature review2.write a literature review as a part of an essay3.cite sources by correct quotation and paragraphs4.give the appropriate documentation to the source you use5.avoid different kinds of plagiarism6.identify common knowledge7.acquire paraphrasing skills8.enhance language skills related with reading and listening material presented in this unit II. Teaching Procedures1 Writing a literature reviewTask 11 The four articles were published right after the Fukushima disaster in Japan and all addressed the topic of potential risks of nuclear radiation.2 Radiation is not so terrible as expected and human beings are exposed to different sources of radiation every day. Whether it will endanger human health or not depends on the duration and strength of radiation exposure.3 Amber Cornelio holds a different attitude from the other three authors. He believes that radiation exposure will certainly raise the risk of getting cancer and government officials downplay its potential danger to justify its use of nuclear power.4 Answers may vary.5 It seems that Text 11, 12, 14 provide more scientific facts about nuclear radiation than Text 13 which is more emotionally charged by using many rhetorical questions and phrases like “I am simply floored”, “let officials be oblivious”, “not to be outdone”, “Do not tell us about that”. Hence it appears less reliable and trustworthy.Task 2Compared with uranium which the production of conventional nuclear power needs, there is more lithium in the sea water which can support 30 million years’ fusion fuel.Task 31 Review the previous related studies2 State the previous s tudies’ limitation3 Announce the direction for further studies2 Writing a self-contained literature reviewTask 11 Stigmatization, a kind of social rejection, is big challenge to the mentally ill. They are rejected by people because of the label they carry or that their behaviors indicate that they belong to a certain labeled group.2 To report the past studies of the topic. Studies have proved that stigmatization of the mentally ill is caused by the public’s belief in myths about the dangerousnes s of the mentally ill and exposing those myths can reduce stigmatization.3 Three articles.4 Pescosolido & Tuch (2000) thought that a common respond to the mentally ill are rejection and fear of violence. Another article concluded that rejection and fear are caused by less contact with mentally ill. Alexander and Link (2003) found that any type of contact with mentally ill individuals reduced perceptions of dangerousness of the target.5 1) What are major causes for the rejection and fear, and can they be reduced?2) This finding is verified by Alexander and Link (2003).Task 2Text 11Title: Risks of Nuclear PowerAuthor(s): Bernard L. CohenSource: .Summary: Radiation from nuclear power is feared to have the potential of causing a cancer or some genetic diseases. This fear, however, is dismissed by Cohen after he compares artificial radiation and the radiation that occurs naturally in our environment, analyzing their respective impact on human health. Cohen separately discusses the different sources of nuclear power risks and arrives at the following conclusions: 1) the probability of real reactor accidents, with the safety system of defense in depth, are extremely small; 2) radioactive waste, if properly handled, causes negligible damage; 3) other radiation problems, such as accidents in transportation or radon exposures in mining, are also not so threatening as they seem to be. In summary he believes that radiation due to nuclear power will cause much fewer cancers and deaths than coal burning. (130 words)Text 12Title: How Radiation Threatens HealthAuthor(s): Nina BaiSource: Scientific AmericanSummary: Nina Bai addresses the widespread concerns over the health effects of radiation exposure in the wake of Fukushima nuclear crisis. She discusses three determinative factors: thelevel, type and duration of radiation exposure. First, radiation sickness usually occurs when there is excessive dose of exposure, though the limits of radiation level differ for the general public, radiation workers, and patients going through medical radiation. Second, of the four types of ionizing radiation, gamma, X-ray, alpha, and beta, the latter two, albeit being lower energy, are more likely to cause health damage. Third, a very high single dose of radiation can be more harmful than the same dosage accumulated over time. Finally, Bai draws on the lesson of Chernobyl, and concludes radiation exposure within reasonable limit is not so fearful and it is good to exercise caution. (136 words)Text 13Title: Should Nuclear Radiation Found in Domestic Milk Come as a Surprise?Author(s): Amber CornelioSource: http://www. Summary: Amber Cornelio (2011) maintains that radiation from Japan’s Fukushima disaster h as threatened the daily life of ordinary Americans. He challenges the government’s view that radioactive materials detected in domestic milk, vegetables and rainwater will pose no public health concern. He suspects that the government is downplaying the potential dangers of radiation to justify its use of nuclear power. He believes the government has failed to do the job of protecting people. In the end, he urges the government to be more responsible and stop building power plants on a faulty line. He warns that covering up the facts is not the key to avoid similar disasters in the future. (108 words) 66Text 14Title:Radiation and Health: The Aftershocks of Japan’s Nuclear DisasterAuthor(s): Susan BlumenthalSource: http://www. Summary: Susan Blumenthal (2011) aims to inform people of nuclear radiation with scientific facts. She starts the essay with a reference to the worldwide spread of fear in the wake of Fukushima disaster and then explains what radiation is. The explanation is followed by a report of different types of radioactive materials released into the air. She goes on to tell that an exposure to those materials will increase the risks of some major diseases. However, she concedes radiation is not so menacing as was assumed and humans are exposed to naturally occurring radiation every day. Whether radiation is harmful to health or not depends on two contexts: the duration and strength of the exposure. She warns that exposure to high doses of radiation can lead to acute health problems. Long-term low dose exposure to radiation is equally fatal. (137words)Task 3The release of substantial amounts of radiation into the atmosphere from Fukushima nuclear plant has triggered widespread concerns over the use of nuclear power and the health effects of radiation exposure. Since the Chernobyl disaster, especially the Fukushima nuclear crisis, many scientists and scholars have attempted to estimate the effect of nuclear radiation on human health. Cohen (2011) believes the fear that nuclear radiation will cause a cancer or other genetic diseases is unnecessary. He made a detailed analysis of the effects of accidents in nuclear power plants,accidents in transporting radioactive materials and escape of radioactive wastes from confinement systems on human health by comparing the effects of coal burning. Cohen arrived at the following conclusions: nuclear radiation, if properly handled, causes negligible damage and much fewer deaths than coal burning. Cohen’s idea is shared by Bai (2011). Bai discussed three determinative factors: the level, type and duration of radiation exposure. She found that radiation sickness usually occurs only when there is excessive dose of exposure. Second, of the four types of ionizing radiation, gamma, X-ray, alpha, and beta, the latter two are more likely to cause health damage. Third, a very high single dose of radiation can be more harmful than the same dosage accumulated over time. Bai concluded that radiation exposure within reasonable limit is not so fearful and it is good to exercise caution. Blumenthal (2011) did similar research. She examined different types of radioactive materials released into the air. She found that an exposure to those materials would increase the risks of some major diseases. However, the radiation is not somenacing as was assumed as humans are exposed to naturally occurring radiation every day. She believes that whether radiation is harmful to health or not depends on two contexts: the duration and strength of the exposure. Only exposure to high doses of radiation or long-term low dose exposure could lead to acute health problems.Contrary to the three scholars, however, Cornelio (2011) maintained that radiation from Japan’s Fukushima disaster threatened the daily life o f ordinary Americans. He challenges the government’s view that radioactive materials detected in domestic milk, vegetables and rainwater will pose no public health concern. He suspects that the government is downplaying the potential dangers of radiation to justify its use of nuclear power. Hence he urges the government to be more responsible and stop building power plants on a faulty line.3 Writing a literature review as a part of an essayTask 11 Content-based instruction (CBI) is an alternative approach to teaching English. In such an approach, language teaching is integrated within discipline-specific content courses. The major goal is to equip students with academic literacy skills across the curriculum. CBI has gained wide acceptance in U.S. undergraduate institutions.2 Numerous research studies demonstrate consistently that content-based second language teaching promotes both language acquisition and academic success.3 More than 10 articles.4 The literature on CBI has focused mainly on its most immediate effects, i.e., the outcomes of one or two semesters in which content-based instruction was provided. Studies on the sustained or long-term benefits of content-based language instruction are scarce.5 The writer plans to study how will C BI impact students’ future performance both in terms of academic courses and English proficiency.Task 2Nuclear Radiation and Its Long-Term Health EffectThere is a constant controversy as to the application of nuclear power and risks from nuclear radiation ever since the Chernobyl disaster. Especially the release of substantial amounts ofradiation into the atmosphere from Japan’s Fukushima Daiichi nuclear power plant in 2010 has triggered the widespread fear and concerns over risks of radiation leaks, radiation exposure, and their impact on people’s health. The commonsensical and intuitive response of the public is that nuclear radiation is most likely to cause a cancer or genetic diseases. Many researchers, however, assured the public that there is no substantial danger as assumed, and nuclear power is not as fearful or menacing as it seems to be. Cohen (2011), Blumenthal (2011) and Bai (2011), for example, cited numerical evidence and resorted to scientific facts to illustrate that a certain level of nuclear radiation risks won’t pose real danger if handled properly with the current technology available or by following the prescribed rules. They do admit the possibility of radiation initiating certain kinds of diseases, though. Only exposure to high doses of radiation or long-term low dose exposure could lead to acute health problems (Bai 2011). Nevertheless, not everyone agrees. Cornelio (2011), on the other hand, holds that nuclear radiation is most likely to threaten people’s health by contaminating milk, vegetables, and rainwater.The literature on the relationship between radiation and health largely focused on the manageability of nuclear risks and played down the damage that nuclear radiation is likely to cause. The researches generally took a detour as to whether there is any solid evidence to bear out the long-term health impact of nuclear radiation. There needs to be more well-grounded studies on the correlation between radiation and health, and on the possible long-term health effects in order to address the concerns of the general public. Besides, we also need to answer questions like “Why is there a disparity between the commonsensical feeling of the public and the explication offered by experts concerning nuclear radiation and health?”, “Are scientists biased and use the facts and statistics to their favor?” and “Is there a long-term negative health impact if one takes moderate doses of nuclear contaminated food over a long period?”Task 3Answers may vary.Task 4Answers may vary.4 CitationTask 1Order Name and date Quotation Paraphrase1 Newell and Simon (1972)√2 Feigenbaum and Feldman (1963) √3 Polya (1945)√4 Minsky (1968)√Task 2Technology plays an ever important role in the making discoveries.

For example, Galileo’s great discovery was attributed to the improv ementof machinery for making telescopes. And thanks to the Deep See Explorer II, life forms are now known to exist in the deeper parts of the Pacific Ocean despite the great pressure, a fact which defies the previous opinion that there was no life at the extreme depth. (Jones, 2001:125)Task 3Human activities are chiefly responsible for climate change. Despite the dispute as to whether global warming is caused by human activities (McGuire, 2001), carbon dioxide has been proved the major factor for climate change. Carbon dioxide will form a thick gas layer as it is constantly building up in the atmosphere. The gas layer is the killer of the ozone layer—the layer which protects the Earth from harmful radiation, thus causing global warming. It is documented that carbon dioxide (CO2) is emitted in a number of ways, among which the burning of fossil fuel can obviously release a great amount of CO2 into the atmosphere (Dalleva, 2007). Another way is deforestation, such as the conversion of forestland to farms, ranches, or urban use. According to Border (2011) 15 to 20% of total carbon dioxide emissions is attributed to land use changes.5 Documentation6 Avoiding plagiarismTask 1Answers may vary.Task 21 The sun rises in the east.

This view has been shifting to a constructivist view over the past decade (Merriënboer, 1997).4 Two components must be present in an instructional design theory. The first component (methods) describes how human learning will be supported, and the second component (situation) describes when certain methods ought to be used (Reigeluth, 1999).5 According to Heimlich (1992), man has always had an interest in the environment both as a source of raw materials and as a refuge for the human spirit. Nowadays, the two main e nvironmental interests are based on the concept of “a better quality of life”, as well as the need to replenish the sources of raw materials. In comparison with the pre-1960s, much greater interest in the environment is currently being expressed.6 According to Gredler (2001), the same factors apply to developing complex skills in a classroom setting as to developing complex skills in any setting. A response must be induced, then reinforced as it gets closer to the desired behavior. Reinforcers have to be scheduled carefully, and cues have to be withdrawn gradually so that the new behaviors can be transferred and maintained.Task 31. Use a synonym of a word or phrase1) They can intrude deep inside the human body where they can damage biological cells and thereby cause a cancer.2) If radioactive material is absorbed into the body, however, it is actually the lower energy alpha and beta radiation that becomes the more dangerous.3) I am simply shocked that officials are understating nuclear radiation levels in the United States as a result of the Fukushima disaster!4) Let officials be forgetful, the rest of us saw it approaching.5) On March 11, 2011, a dimension 9.0 earthquake attacked Japan, causing a destructive tsunami that tore through the coastal regions and leveled the villages in its path.2. Change the order of information1) How the spent fuel is dealt with determines the effects of routine releases of radioactivity from nuclear plants.2) It is difficult to measure the effects of long-term, low-dose radiation.3) One indication of the terrible situation in Japan is that no sensible man wants to visit there again for the next 80 to 100 years.4) Understandably, panic among masses is what the authorities try to avoid.5) Burns or other symptoms of acute radiation syndrome (ARS) vary from person to persondepending on the strength of radiation and the level of exposure.3. Change from the active to the passive or vice versa1) Our cancer risk should be eventually increased by 0.002% (one part in 50,000), thus our life expectancy reduced by less than one hour due to the radiation brought by nuclear technology. 2) 180,000 people have been evacuated by the Japanese government from within a 20 kilometer radius of the Fukushima Daiichi complex.3) Farmers in Japan were asked to keep cows and cattle in barns by Government officials as radioactive contamination of milk spread from Fukushima prefecture, north of Tokyo.4) A sheet of paper can often block Alpha and beta particle radiation as it is lower energy.5) A broad range of acute health problems will arise only among the individuals who are exposed to high doses of radiation such as reactor worker.4. Change the positive into the negative and vice versa1) Since our body cells fail to distinguish between natural radiation and radiation from the nuclear industry.2) No number of noticeable deaths from coal burning was larger than in an air pollution incident where there were 3,500 extra deaths in one week.3) Should any increase in radiation due to a nuclear disaster instead of naturally occurring, be of concern?4) The dairy industry will not stop working closely with federal and state government agencies to ensure that we maintain a safe milk supply.5) Almost no one will experience a broad range of acute health problems due to their exposure to high doses of radiation except for the individuals close to the source of radiation such as reactor workers.5. Change personal nouns into impersonal nouns and vice versa1) The attack of sex cells can cause genetic diseases in progeny.2) Unawareness of the danger led parents to serve contaminated milk to their children.3) Our perplexity results from the increases in diseases, obesity and erratic behavior among our malnutritioned populace.4) Then again, officials tend to downplay everything, so that panic doesn’t occur among the masses.5) A person who is exposed to low dose but long-term radiation will develop chronic health condition including cancer.6. Change complex sentences into simple sentences and vice versa1) There is little likelihood, if any, for the failure of each system in this series of back-ups exists.2) We should not be worried at all.3) The increase in cancer risk is too small to determine unless many exposed subjects are studies.4) Any exposure will lead to certain damage and safety problem.5) Despite a lot of news distraction, we still notice the dire current situation.8 Enhancing your academic languageReading: Text 111 Match the words with their definitions.1 i2 f3 g4 c5 h6 a7 b8 e9 d 10 j2 Complete the following expressions or sentences by using the target words listed below with the help of the Chinese in brackets.

Is the cloud computing perfect now?
Cloud computing, or the cloud, is a colloquial expression used to describe a variety of different types of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet. And with various terminals developing fast, the durative, massive and intricate computing related to these terminals really become urgent problems. And for the present, cloud computing is a solution. But if we allow the cloud computing to contact with our private information, is it secure enough? And in which field can we improve the security? In the Security Benefits of Cloud Computing, Felician Aleca introduced the cloud computing and analyze its extensive application in the Internet field. It clarified many advantages of the cloud computing. In addition, it also introduced some major security benefits for individuals or companies which are provided by the cloud computing. But nearly every Internet technique will produce some latent vulnerability. In an essay about computer hacker, How Do Computer Hackers “Get Inside”a Computer?, by Julie J. C. H. Ryan, it introduced the various ways that hackers use to invade into computer. And there are three major patterns of these ways, which are gaining access to the stored contents of a computer system, gaining access to the processing capabilities of system, or capturing information being communicated between systems (J.C.H.Ryan,2004). And in the end, it reminds the importance of protecting our computer. As we all known, the personal terminals always store many private information, and the cloud store the users’ data on the Internet servers , in this way, it will cause large-scale information leakage once the hackers invade to these servers online. In fact, we are becoming more vulnerable while we enjoy the benefit of centralized processing by cloud computing. So how to improve the security of the users’ data stored in the cloud is real ly worth studying.
