literature review 范本
literature review 范本A literature review is a comprehensive and critical evaluation of existing scholarship on a particular topic. It aims to identify and synthesize relevant research, provide a summary of current knowledge on the topic, and identify gaps or areas for further study. Below is a sample literature review on the topic of mental health in adolescence:Title: Mental Health in Adolescence: A Comprehensive Literature ReviewIntroduction:Adolescence is a critical period in a person's life, characterized by significant physical, psychological, and social changes. Mental health issues can significantly impact the well-being and future trajectories of adolescents. Therefore, understanding the current research on mental health in this population is crucial to inform policy decisions, intervention strategies, and future research. This literature review aims to synthesize the existing knowledge on mental health in adolescence, identify the factors contributing to mental health issues, and explore potential interventions to improve the well-being of adolescents.Methodology:This review utilizes a systematic approach to identify relevant scholarly articles and research papers. Databases such as PubMed, PsycINFO, and Google Scholar were searched using specific keywords, including "adolescent mental health," "mental health interventions," "risk factors," and "protective factors." The search was limited to articles published in the last ten years to ensure theinclusion of recent research. The initial search yielded 500 articles, which were screened based on their relevance to the topic. After the screening process, 50 articles were included in the final review. Findings:Mental health issues in adolescence are multifaceted and influenced by various individual, familial, and social factors. The most prevalent mental health disorders among adolescents include anxiety, depression, and substance abuse disorders. Risk factors such as familial history of mental illness, adverse childhood experiences, peer pressure, and academic stress significantly contribute to the development of mental health issues in this population.Protective factors, on the other hand, act as buffers and promote resilience in adolescents. These include social support, strong family relationships, positive school environments, and access to mental health services. Interventions targeted at enhancing protective factors and reducing risk factors have shown promising results in improving the mental well-being of adolescents. Cognitive-behavioral therapy, mindfulness-based interventions, and peer support programs have emerged as effective interventions for managing mental health disorders in this population.Despite the growing body of research on adolescent mental health, several gaps exist in the current literature. Limited research is available on the mental health concerns of specific subgroups, such as LGBTQ+ adolescents and those from marginalized communities. Furthermore, more research is needed to understand the long-term impacts of mental health interventions and the role of technologyin mental health promotion and prevention.Conclusion:This literature review provides a comprehensive overview of the current research on mental health in adolescence. It highlights the importance of addressing mental health issues in this population, identifies the factors contributing to these issues, and explores potential avenues for intervention. Future research should focus on filling the existing gaps in knowledge, developing culturally sensitive interventions, and utilizing technology to improve mental health outcomes among adolescents. Ultimately, a holistic approach incorporating social, familial, and individual factors is crucial for promoting the mental well-being of adolescents.。

Text Recognition with Machine Learning based on Text StructureLiterature ReviewYifan Shi Student ID:27291944Email:ys1n13@MSc Artificial IntelligenceFaculty of Physical Sciences&Eng,University of SouthamptonAbstract—The fast developing Machine Learning algorithms introduced to semantic area nowadays has brought vast techniques in text recognition,classification, and processing.However,there is always a contradiction between accuracy and speed,as higher accuracy generally represents more complicated system as well as large training database.In order to achieve a balance between fast speed and good accuracy,many brilliant designs are used in text processing.In this literature review,these efforts are introduced in three layers:Natural-Language Processing,Text Classification,and IBM Watson System.Keywords—Machine Learning,Natural-Language Processing,Text Classification,IBM WatsonI.I NTRODUCTIONThe growing popularity of the Internet has brought increasing number of users online,with a vast amount of messages,blogs,articles,etc.to be dealt with.These texts,known as natural-language texts,contain possible useful information but take a long time for human to read,understand and deal with.Despite the popular search engine technology nowadays in helping users tofind the sources with keywords,semantic techniques are also needed by many companies to improve their user-friendly working environment.In this literature review,I will introduce several important semantic techniques,starting from the most basic Natural-Language Processing,concentrating in the meaning of words and sentences,followed by Text Classification which is focused on paragraphs and articles.Then,I will introduce a landmark system named IBM Watson,which has DeepQA as its working pipeline.Finally,a conclusion will be included to give some comments on these techniques.II.N ATURAL L ANGUAGE P ROCESSING In order to deal with the human natural-language, it is necessary to transform the unstructured text into well-structured tables of explicit semantics (Ferrucci,2012).According to Liddy(2001), Natural-Language Processing(NLP)is a series of computational techniques used to analyze and represent naturally organized text in order to achieve certain tasks and applications.Collobert and Weston(2008)have categorized NLP tasks into six types:Part-Of-Speech Tagging,Chunking,Named Entity Recognition,Semantic Role Labeling, Language Models,and Semantically Related Words.In addition to this,they also implemented Multitask Learning with Deep Neural Networks to build a successful unified architecture which avoided traditional large amount of empirical hand-designed features to train the system by using backpropagation training(Collobert et al.,2011).III.T EXT C LASSIFICATIONOne of the simple way to represent an article for a learning algorithm is to use the number of times that distinct words appear in the document (Joachims,2005).However,due to the large amount of possible words used in articles,it would create a very high dimensional space of features.Joachims(1999)suggests a TransductiveSupport Vector Machines to do classification because of its effective learning ability even in high dimensional feature space.Rather than using non-linear Support Vector Machine(SVM), Dumais et al.(1998)compared linear SVM with another four different learning algorithms which are Find Similar,Decision Trees,Naive Bayes, and Bayes Nets,which also supports SVM in text classification because of its high accuracy,fast speed as well as its simple model.Sebastiani(2002) also recommends Neural Network as a potential selection in text classification in that its accuracy is only slightly lower than SVM in comparison. The cross-document comparison of small pieces of text,using linguistic features such as noun phrases,and synonyms is introduced by Hatzivassiloglou et al.(1999).The similarity of two paragraphs is defined by the same action conducted on the same object by the same actor. Therefore,drawing features according to nouns and verbs would generally conclude a paragraph into several primitive elements.In addition to the similar primitive elements,restrictions such as ordering, distances and primitive(matching noun and verb pairs)are also implemented to exclude weakly related features.The feature selection methods can effectively reduce the dimensions of dataset (Ikonomakis,2005)while keeping the performance of classification.To make sure which words are to be kept,an Evaluation function has been introduced by Soucy and Mineau(2003)to measure how much information we can get by classifying through a single word.Another improvement by Han et al. (2004)is to use Principal Component Analysis (PCA)to reduce the dimension in transformation of features.Nigam and Mccallum(2000)combine Expectation-Maximization and Naive Bayes classifier to train the classifier with certain amount of labeled texts followed by large amount of unlabeled documents,which realizes the automatic training without huge amount of hand-designed training data.IV.IBM W ATSONThe IBM Watson project has shown us that computer system in open-domain question-answering(QA)is possible to beat human champions in Jeopardy.As Ferrucci(2012) mentioned,the structure of Watson is more complicated than any single agent as it has hundreds of algorithms working together,in the way that Minsky(1988)introduced in Society of Mind.Generally,Watson consists of parts which are DeepQA,Natural Language Processing(NLP), Machine Learning(ML),and Semantic Web and Cloud Computing(Gliozzo et al.,2013).The DeepQA system analyzes the question by different algorithms,giving different interpretations of questions and forming queries for each question (Ferrucci,2012).It provides all the possible answers to the question with the evidences and the scores for each candidate,which would generate a ranking of candidate answers with the likelihood of correctness.The Machine Learning algorithms are used to train the weights in its evaluating and analyzing algorithms(Gliozzo et al.,2013).The clue that Watson uses in searching is named as lexical answer type(LAT),which tells Watson what the question is asking about and what kind of things it needs to look for.Before doing searching, it would generate prior knowledge of type label, known as‘direction’,to each candidate answer and search evidences for and against this‘type direction’(Ferrucci,2012).The DeepQA also has a high requirement in Grammar-based and syntactic analysis techniques,for example,relation extraction techniques in getting possible relations between words,based on a rule-based approach.In addition,the ability of breaking the question down into sub-questions by logics also improved Watsons performance(Ferrucci,2012),which enables Watson tofind results for each smaller questions and combine them together.In correspondence to the ability of breaking down questions,it can also generate the score for the original question based on the evidence for sub-questions.To simulate human knowledge,Watson also uses self-contained database.However,this requirement has led to its great hardware cost.Watson also needs to do automatic text analysis and knowledge extraction to update its database,because of the enormous amount of work and the insurance ofinput-knowledge accuracy.However,the use of self-contained database is costly,that only few institutions can afford the hardware expense,which makes the application of Watson expensive.Another limitation is that the structured resource is relatively narrow compared with vast unstructured natural-language texts.One of the possible improvement is to use online data and ordinary online search engine tofind possible related articles and analyze them with PC clients.Despite the tradeoff between accuracy and cost,because of the possible the unreal data and incorrect information online,it makes the technique more realizable in general.V.C ONCLUSIONAs can be seen from the content above,most techniques used in text analysis are based on‘word feature’extraction,word types,and relations, which are all semantic techniques.While Watson also uses searching techniques tofind the exact answer shown in text.However,the machines lack the ability to conclude the main idea in a paragraph,which is more related with abstract logic thinking.While the way that human read concerns not only on vocabularies and meanings, but also the structure of paragraph and the location of sentences,for example,thefirst sentence in the paragraph usually guides the following content, which helps tell the significance of the sentences and words.Therefore,using machine learning to analyze the structure of an article and combining with the meaning of every sentence might generate the ability to conclude the main idea,which can be used in text scanning and classification.R EFERENCES[1]S.Dumais,J.Platt,D.Heckerman,and M.Sahami,InductiveLearning Algorithms and Representations for Text Categoriza-tion,Proceedings of the seventh international conference on Information and knowledge management,pp-148-155,1998.

II. The purposes of literature review And Its Components A. The Purposes On the one hand, it helps you broaden the view and perspective of the topic for your graduation thesis. On the other hand, it helps you narrow down the topic and arrive at a focused research question. B. Its Components There are six parts in a complete Literature Review. 标题与作者(title and author) 摘要与关键词(abstract and key words) 引⾔(introduction) 述评(review) 结论(conclusion) 参考⽂献(references) III. Classification of Source Materials How can we locate the materials relevant to our topics better and faster? Basically, all these source materials may be classified into four majors of sources. A: Background sources: Basic information which can usually be found in dictionaries and encyclopedia complied by major scholars or founders of the field. Three very good and commonly recommenced encyclopedias are encyclopedias ABC, namely, Encyclopedia Americana, Encyclopedia Britannica, and Collier’s Encyclopedia. There are also reference works more specialized, such as The Encyclopedia of Language and Linguistics for linguistics and TEFL studies. Moreover, you may also find Encyclopedia on the web. B: Primary sources Those providing direct evidence, such as works of scholars of the field, biographies or autobiographies, memoirs, speeches, lectures, diaries, collection of letters, interviews, case studies, approaches, etc. Primary sources come in various shapes and sizes, and often you have to do a little bit of research about the source to make sure you have correctly identified it. When a first search yields too few results, try searching by broader topic; when a search yields too many results, refine your search by narrowing down your search. C: Secondary sources Those providing indirect evidence, such as research articles or papers, book reviews, assays, journal articles by experts in a given field, studies on authors or writers and their works, etc. Secondary sources will inform most of your writing in college. You will often be asked to research your topic using primary sources, but secondary sources will tell you which primary sources you should use and will help you interpret those primary sources. To use theme well, however, you need to think critically them. There are two parts of a source that you need to analyze: the text itself and the argument within the text. D: Web sources The sources or information from websites. Web serves as an excellent resource for your materials. However, you need to select and evaluate Web sources with special care for very often Web sources lack quality control. You may start with search engines, such as Google, Yahoo, Ask, Excite, etc. It’s a good idea to try more than one search engine, since each locates sources in its own way. When using websites for information, be sure to take care for the authorship and sponsorship. If they are both unclear, be critical when you use information. The currency of website information should also be taken into account. Don’t use too out information dated for your purpose. IV. Major strategies of Selecting Materials for literature review A. Choosing primary sources rather than secondary sources If you have two sources, one of them summarizing or explaining a work and the other the work itself, choose the work itself. Never attempt to write a paper on a topic without reading the original source. B. Choosing sources that give a variety of viewpoints on your thesis Remember that good argument essays take into account counter arguments. Do not reject a source because it makes an argument against you thesis. C. Choosing sources that cover the topic in depth Probably most books on Communicative Language Teaching mention William Littlewood, but if this your topic, you will find that few sources cover the topic in depth. Choose those. D. Choosing sources written by acknowledged experts If you have a choice between an article written by a freelance journalist on Task-based Teaching and one written by a recognized expert like David Nunan, Choose the article by the expert. E. Choosing the most current sources If your topic involves a current issue or social problem or development in a scientific field, it is essential to find the latest possible information. If all the books on these topics are rather old, you probably need to look for information in periodicals. V. Writing a literature Review A. When you review related literature, the major review focuses should be: 1. The prevailing and current theories which underlie the research problem. 2. The main controversies about the issue, and about the problem. 3. The major findings in the area, by whom and when. 4. The studies which can be considered the better ones, and why. 5. Description of the types of research studies which can provide the basis for the current theories and controversies. 6. Criticism of the work in the area. B. When you write literature review, the two principles to follow are: 1. Review the sources that are most relevant to your to your thesis. 2. Describe or write your review as clear and objective as you can. C. Some tips for writing the review: 1. Define key terms or concepts clearly and relevant to your topic. 2. Discuss the least-related references to your question first and the most related references last. 3. Conclude your review with a brief summary. 4. Start writing your review early. VI. ⽂献综述主要部分的细节性提⽰和注意事项 主要部分细节提⽰： 引⾔(Introduction) 引⾔是⽂献综述正⽂的开始部分，主要包括两个内容：⼀是提出问题;⼆是介绍综述的范围 和内容。

第1课知识的悖论The Paradox of KnowledgeThe greatest achievement of humankind in its long evolution from ancient hominoid ancestors to its present status is the acquisition and accumulation of a vast body of knowledge about itself, the world, and the universe. The products of this knowledge are all those things that, in the aggregate, we call "civilization," including language, science, literature, art, all the physical mechanisms, instruments, and structures we use, and the physical infrastructures on which society relies. Most of us assume that in modern society knowledge of all kinds is continually increasing and the aggregation of new information into the corpus of our social or collective knowledge is steadily reducing the area of ignorance about ourselves, the world, and the universe. But continuing reminders of the numerous areas of our present ignorance invite a critical analysis of this assumption.In the popular view, intellectual evolution is similar to, although much more rapid than, somatic evolution. Biological evolution is often described by the statement that "ontogeny recapitulates phylogeny"--meaning that the individual embryo, in its development from a fertilized ovum into a human baby, passes through successive stages in which it resembles ancestral forms of the human species. The popular view is that humankind has progressed from a state of innocent ignorance, comparable to that of an infant, and gradually has acquired more and more knowledge, much as a child learns in passing through the several grades of the educational system. Implicit in this view is an assumption that phylogeny resembles ontogeny, so that there will ultimately be a stage in which the accumulation of knowledge is essentially complete, at least in specific fields, as if society had graduated with all the advanced degrees that signify mastery of important subjects.Such views have, in fact, been expressed by some eminent scientists. In 1894 the great American physicist Albert Michelson said in a talk at the University of Chicago:While it is never safe to affirm that the future of Physical Science has no marvels in store even more astonishing than those of the past, it seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice .... The future truths of Physical Science ate to be looked for in the sixth place of decimals.In the century since Michelson's talk, scientists have discovered much more than the refinement of measurements in the sixth decimal place, and none is willing to make a similar statement today. However, many still cling to the notion that such a state of knowledge remains a possibility to be attained sooner or later. Stephen Hawking, thegreat English scientist, in his immensely popular book A Brief History of Time (1988), concludes with the speculation that we may "discover a complete theory" that "would be the ultimate triumph of human reason--for then we would know the mind of God." Paul Davies, an Australian physicist, echoes that view by suggesting that the human mind may be able to grasp some of the secrets encompassed by the title of his book The Mind of God (1992). Other contemporary scientists write of "theories of everything," meaning theories that explain all observable physical phenomena, and Nobel Laureate Steven Weinberg, one of the founders of the current standard model of physical theory, writes of his Dreams of a Final Theory (1992).Despite the eminence and obvious yearning of these and many other contemporary scientists, there is nothing in the history of science to suggest that any addition of data or theories to the body of scientific knowledge will ever provide answers to all questions in any field. On the contrary, the history of science indicates that increasing knowledge brings awareness of new areas of ignorance and of new questions to be answered.Astronomy is the most ancient of the sciences, and its development is a model of other fields of knowledge. People have been observing the stars and other celestial bodies since the dawn of recorded history. As early as 3000 B.C. the Babylonians recognized a number of the constellations. In the sixth century B.C., Pythagoras proposed the notion of a spherical Earth and of a universe with objects in it chat moved in accordance with natural laws. Later Greek philosophers taught that the sky was a hollow globe surrounding the Earth, that it was supported on an axis running through the Earth, and chat stars were inlaid on its inner surface, which rotated westward daily. In the second century A.D., Ptolemy propounded a theory of a geocentric (Earth-centered) universe in which the sun, planets, and stars moved in circular orbits of cycles and epicycles around the Earth, although the Earth was not at the precise center of these orbits. While somewhat awkward, the Ptolemaic system could produce reasonably reliable predictions of planetary positions, which were, however, good for only a few years and which developed substantial discrepancies from actual observations over a long period of time. Nevertheless, since there was no evidence then apparent to astronomers that the Earth itself moves, the Ptolemaic system remained unchallenged for more than 13 centuries.In the sixteenth century Nocolaus Copernicus, who is said to have mastered all the knowledge of his day in mathematics, astronomy, medicine, and theology, became dissatisfied with the Ptolemaic system. He found that a heliocentric system was both mathematically possible and aesthetically more pleasing, and wrote a full exposition of his hypothesis, which was not published until 1543, shortly after his death. Early inthe seventeenth century, Johannes Kepler became imperial mathematician of the Holy Roman Empire upon the death of Tycho Brahe, and he acquired a collection of meticulous naked-eye observations of the positions of celestial bodies chat had been made by Brahe. On the basis of these data, Kepler calculated that both Ptolemy and Copernicus were in error in assuming chat planets traveled in circular orbits, and in 1609 he published a book demonstrating mathematically chat the planets travel around the sun in elliptical orbits. Kepler's laws of planetary motion are still regarded as basically valid.In the first decade of the seventeenth century Galileo Galilei learned of the invention of the telescope and began to build such instruments, becoming the first person to use a telescope for astronomical observations, and thus discovering craters on the moon, phases of Venus, and the satellites of Jupiter. His observations convinced him of the validity of the Copernican system and resulted in the well-known conflict between Galileo and church authorities. In January 1642 Galileo died, and in December of chat year Isaac Newton was born. Modern science derives largely from the work of these two men.Newton's contributions to science are numerous. He laid the foundations for modem physical optics, formulated the basic laws of motion and the law of universal gravitation, and devised the infinitesimal calculus. Newton's laws of motion and gravitation are still used for calculations of such matters as trajectories of spacecraft and satellites and orbits of planets. In 1846, relying on such calculations as a guide to observation, astronomers discovered the planet Neptune.While calculations based on Newton's laws are accurate, they are dismayingly complex when three or more bodies are involved. In 1915, Einstein announced his theory of general relativity, which led to a set of differential equations for planetary orbits identical to those based on Newtonian calculations, except for those relating to the planet Mercury. The elliptical orbit of Mercury rotates through the years, but so slowly that the change of position is less than one minute of arc each century. The equations of general relativity precisely accounted for this precession; Newtonian equations did not.Einstein's equations also explained the red shift in the light from distant stars and the deflection of starlight as it passed near the sun. However, Einstein assumed chat the universe was static, and, in order to permit a meaningful solution to the equations of relativity, in 1917 he added another term, called a "cosmological constant," to the equations. Although the existence and significance of a cosmological constant is still being debated, Einstein later declared chat this was a major mistake, as Edwin Hubble established in the 1920s chat the universe is expanding and galaxies are receding fromone another at a speed proportionate to their distance.Another important development in astronomy grew out of Newton's experimentation in optics, beginning with his demonstration chat sunlight could be broken up by a prism into a spectrum of different colors, which led to the science of spectroscopy. In the twentieth century, spectroscopy was applied to astronomy to gun information about the chemical and physical condition of celestial bodies chat was not disclosed by visual observation. In the 1920s, precise photographic photometry was introduced to astronomy and quantitative spectrochemical analysis became common. Also during the 1920s, scientists like Heisenberg, de Broglie, Schrodinger, and Dirac developed quantum mechanics, a branch of physics dealing with subatomic particles of matter and quanta of energy. Astronomers began to recognize that the properties of celestial bodies, including planets, could be well understood only in terms of physics, and the field began to be referred to as "astrophysics."These developments created an explosive expansion in our knowledge of astronomy. During the first five thousand years or more of observing the heavens, observation was confined to the narrow band of visible light. In the last half of this century astronomical observations have been made across the spectrum of electromagnetic radiation, including radio waves, infrared, ultraviolet, X-rays, and gamma rays, and from satellites beyond the atmosphere. It is no exaggeration to say chat since the end of World War II more astronomical data have been gathered than during all of the thousands of years of preceding human history.However, despite all improvements in instrumentation, increasing sophistication of analysis and calculation augmented by the massive power of computers, and the huge aggregation of data, or knowledge, we still cannot predict future movements of planets and other elements of even the solar system with a high degree of certainty. Ivars Peterson, a highly trained science writer and an editor of Science News, writes in his book Newton's Clock (1993) that a surprisingly subtle chaos pervades the solar system. He states:In one way or another the problem of the solar system's stability has fascinated and tormented asrtonomers and mathematicians for more than 200 years. Somewhat to the embarrassment of contemporary experts, it remains one of the most perplexing, unsolved issues in celestial mechanics. Each step toward resolving this and related questions has only exposed additional uncertainties and even deeper mysteries.Similar problems pervade astronomy. The two major theories of cosmology, general relativity and quantum mechanics, cannot be stated in the same mathematical language, and thus are inconsistent with one another, as the Ptolemaic and Copernicantheories were in the sixteenth century, although both contemporary theories continue to be used, but for different calculations. Oxford mathematician Roger Penrose, in The Emperors New Mind (1989), contends that this inconsistency requires a change in quantum theory to provide a new theory he calls "correct quantum gravity."Furthermore, the observations astronomers make with new technologies disclose a total mass in the universe that is less than about 10 percent of the total mass that mathematical calculations require the universe to contain on the basis of its observed rate of expansion. If the universe contains no more mass than we have been able to observe directly, then according to all current theories it should have expanded in the past, and be expanding now, much more rapidly than the rate actually observed. It is therefore believed that 90 percent or more of the mass in the universe is some sort of "dark matter" that has not yet been observed and the nature of which is unknown. Current theories favor either WIMPs (weakly interacting massive particles) or MACHOs (massive compact halo objects). Other similar mysteries abound and increase in number as our ability to observe improves.The progress of biological and life sciences has been similar to that of the physical sciences, except that it has occurred several centuries later. The theory of biological evolution first came to the attention of scientists with the publication of Darwin's Origin of Species in 1859. But Darwin lacked any explanation of the causes of variation and inheritance of characteristics. These were provided by Gregor Mendel, who laid the mathematical foundation of genetics with the publication of papers in 1865 and 1866.Medicine, according to Lewis Thomas, is the youngest science, having become truly scientific only in the 1930s. Recent and ongoing research has created uncertainty about even such basic concepts as when and how life begins and when death occurs, and we are spending billions in an attempt to learn how much it may be possible to know about human genetics. Modern medicine has demonstrably improved both our life expectancies and our health, and further improvements continue to be made as research progresses. But new questions arise even more rapidly than our research resources grow, as the host of problems related to the Human Genome Project illustrates.From even such an abbreviated and incomplete survey of science as this, it appears that increasing knowledge does not result in a commensurate decrease in ignorance, but, on the contrary, exposes new lacunae in our comprehension and confronts us with unforeseen questions disclosing areas of ignorance of which we were not previously aware.Thus the concept of science as an expanding body of knowledge that will eventually encompass or dispel all significant areas of ignorance is an illusion. Scientists and philosophers are now observing that it is naive to regard science as a process that begins with observations that are organized into theories and are then subsequently tested by experiments. The late Karl Popper, a leading philosopher of science, wrote in The Growth of Scientific Knowledge (1960) chat science starts from problems, not from observations, and chat every worthwhile new theory raises new problems. Thus there is no danger that science will come to an end because it has completed its task, clanks to the "infinity of our ignorance."At least since Thomas Kuhn published The Structure of Scientific Revolutions (1962), it has been generally recognized that observations are the result of theories (called paradigms by Kuhn and other philosophers), for without theories of relevance and irrelevance there would be no basis for determining what observations to make. Since no one can know everything, to be fully informed on any subject (a claim sometimes made by those in authority) is simply to reach a judgment that additional data are not important enough to be worth the trouble of securing or considering.To carry the analysis another step, it must be recognized that theories are the result of questions and questions are the product of perceived ignorance. Thus it is chat ignorance gives rise to inquiry chat produces knowledge, which, in turn, discloses new areas of ignorance. This is the paradox of knowledge: As knowledge increases so does ignorance, and ignorance may increase more than its related knowledge.My own metaphor to illustrate the relationship of knowledge and ignorance is based on a line from Matthew Arnold: "For we are here as on a darkling plain...." The dark chat surrounds us, chat, indeed, envelops our world, is ignorance. Knowledge is the illumination shed by whatever candles (or more technologically advanced light sources) we can provide. As we light more and more figurative candles, the area of illumination enlarges; but the area beyond illumination increases geometrically. We know chat there is much we don't know; but we cannot know how much there is chat we don't know. Thus knowledge is finite, but ignorance is infinite, and the finite cannot ever encompass the infinite.This is a revised version of an article originally published in COSMOS 1994.

Lovelock (1983) is based on the degrees of customers’participation in promotion ofservices to divide service into high-contact services, middle-contact services and loers participate in all or most of the activities in the serviceprocess, such as the services offered by schools, public transport sector. Middle-contact services mean that customers are involved in part of the activities in the service process, such as the services provided by banks and laean that in the service process, customers less contact unications industry.According to service modes and satisfaction degree, A. Parasuraman,V alarie A. Zeithaml and Leonard L. Berry (PZB) (1985) divided services into standardization services and personalized services. In the process of offering standardization services, service providers are based on certain standards and processes to provide services for objects. In provision of personalized services, service providers are in accordance ents to provide guests et al (2004) are based on the status of contact beters and service organizations to divide services into continuous, membership services, such as the services offered by banks, insurance panies, automobile associations, and so on; continuous, non-membership services such as services provided by radio stations, police, and so on; discontinuous, membership services such as phone purchase services, embership services such as mail order.Roger (1986) er interaction or customization and the degree of laborintensiveness to classify services, alloanagement and break do other industry (James Mona, 2000). Roger (1986) proposed the service process matrix, as shoatrix, services are divided by tensions, ined significant differences in delivery process. The vertical dimension describes the level of labor intensity and the horizontal dimension measures the degree of customer interaction and customization. The hospitality industry is laid in the service factory catalogue; it is a capital-intensive industry in the upper roent-->in real estate, acmodation facilities and energy, and so on. For the degree of interaction and customization, the services that a hotel provides is more standardized rather than customized (.51lunes Mona, 2000). Roger Schmener (1986) also pointed out those managers of services in no matter e mon challenges as shomarize the characteristics and types of services of hotels. First of all, services in hotels belong to high-contact services, guests are involved in most of the process of services, any mistakes of service providers are directly exposed in front of customers(Byeong and Haemoon, 2004). Then, services of hotels bines features of standardized services and personalized services. Service personnel provide standardized services embership services, for a same customer, once the service of a time finishes, it a service experience, the acquired experience is unique. Hoaintain long-term, good service experience of consumers is very difficult for hotel management, to maintain a stable, high-quality and intuitive service is very important (Juwaheer and Ross, 2003).。

This packet is not intended to replace instructor guidelines and should not be used in that manner. The packet’s intended use is as a supplement to classroom instruction on assembling a literature review. Therefore, it contains only general information that must be tailored to fit specific guidelines as required by your discipline and by your instructor.This packet is subdivided into six sections:I. General InformationStates what a literature review is and what purpose it serves.II. ProcessGives step-by-step instructions on how to get started on your literature review.III. OrganizationExplains the two most common ways of arranging information in a literature review.IV. FormatProvides descriptions for two of the most common formats used in a literature review, the item to item comparison and contrast (Format A) and the criteria to criteria comparison and contrast (Format B).V. ChecklistAllows appraisal of your completed literature review to assure that it follows all necessary guidelines.VI. ResourcesLists helpful resources used to compile this packet so that you may obtain further information.M General Information MDefinitionLiterature reviews can have two roles: In their first role, they function as a stand-alone paper. At other times they will actually be part of a larger research thesis. In this handout, literature reviews will be referred to in the stand-alone sense. As a stand-alone paper, literature reviews are multi-layered and are more formal and detailed than book reviews. As the author of a literature review, you must become familiar with a large amount of research on a specific topic. You will then develop your own thesis about the topic related to this research. After this, you will classify and critically analyze research on the topic by making a comparison between several different studies and by emphasizing how these studies and their comparison relate to your own thesis.In effect, a literature review is a paper that compiles, outlines and evaluates previously established research and relates it to your own thesis. It provides a context for readers as if theywere researching the topic on their own. Just from reading your paper, readers should be able to gain insight into the amountand quality of research on the topic. Your thesis and the literature reviewed serve several important functions within the paper:Your thesis creates a foundation for the literature review because it helps narrow the topic by providing a sense of direction; however, you will have to conduct some initial research and reading before deciding on an appropriate thesis. Your personal thesis may be a statement addressing some of the following situations: “why your research needs to be carried out, how you came to choose certain methodologies or theories to work with, how your work adds to the research already carried out”(Brightwell, G. and Shaw, J., 1997-98), or it may present some other logical perspective.Reviewed literature is organized in a logical manner that best suits the topic of the review and the hypothesis of the literature (see Organization and Format). The selected method of organization and style of format should draw attention to similarities and differences among the reviewed literature; these similarities and differences are based on specific criteria you revealed in the literature review’s introduction. According to Brightwell and Shaw (1997-98), your goal in the body of the review “. . . should be to evaluate and show relationships between the work already done (Is Researcher Y’s theory more convincing than Researcher X’s? Did Researcher X build on the work of Researcher Y?) and between this work and your own [thesis].” Additional information on these topics can be found in the Organization and Format sections of this packet. Therefore, carefully planned organization is an essential part of any literature review.PurposeAlthough literature reviews may vary according to discipline, their overall goal is similar. A literature review serves as a compilation of the most significant sources on a subject and relates the findings of each of these sources in a rational manner while supporting the literature review author’s own thesis. A literature review establishes which sources are most relevant to its author’s point and which sources are most credible to the discipline at hand.In a literature review, the results of previous research are summarized, organized and evaluated. Discipline-SpecificityA literature review’s organization, format, level of detail and citation style may vary according to discipline because different disciplines have different audiences. Examples here pertain to the natural sciences, social sciences and humanities.Natural and social sciences The author of a literature review in the natural or social sciences must pay close attention to measurements, study populations and technical aspects of experimental findings. Typically, a portion of the natural or social sciences literature review is set aside for reviewing sources on the primary topic. Then, a comparative analysis or discussion section is used to analyze the similarities and differences among the sources, tying them in with the literature review author’s original thesis.Humanities The author of a literature review in the humanities usually does not set aside a special section for reviewing the sources; instead, citations may be found randomly throughout the paper. The literature being reviewed is arranged according to paragraphs based on the author’s points, which in turn, support the author’s thesis. The paper itself may not be called a literature review at all. It is more likely to be called a critical analysis.Remember that the best bet for determining what type of literature review is appropriate for your course is checking with the instructor prior to beginning research.REVIEW1. What is the purpose of a literature review? What is the connection between theauthor’s thesis and the literature being reviewed?2. What discipline will your literature review be classified in?M Process M1. Find several articles that deal with your research topic. Sometimes it is helpful to review the bibliography of one of the first scholarly sources that you encounter and compare it to the bibliographies of other sources on the topic. If the same source is listed within several of these bibliographies, it is probably a fundamental, credible source that will aid you in your review.2. Before you begin reviewing literature, realize that you are looking to accomplish two things:A. Defining your research problem/thesis (examples: finding a flaw inresearch, continuing previous research, etc . . .)B. Reading and evaluating significant works that are relevant to yourresearch problem.You will be conducting Steps A and B simultaneously because the two form a circular pattern. As you read related sources (Step B), you define your problem, and as you define your problem (Step A) you will more easily be able to decide what material is relevant enough to be worthy of reading (Step B).3. Once you begin reviewing, make an entry with complete bibliographical information and comments for each work that you are going to include in the review.4. Compare the articles by evaluating the similarities and differences among them. This will be the initial stage in the formulation of your thesis.5. Form a thesis that is clearly written and can be logically supported by the literature you will include in your review.6. View the articles briefly again and jot down any notes that seem to relateto your thesis.7. Decide which organizational pattern and format are best for the topic of your review.8. Construct an appropriate outline for the literature review.9. Write an introduction that introduces the topic, reveals your thesis statement, and arranges key issues.10. Organize and write the body of your paper according to the appropriate format: topical or chronological.11. Write a conclusion that reconciles similarities and differences on the topic and reemphasizes the criteria used to arrive at this conclusion./doc/8b508cc25fbfc77da269b1c1.html plete the final draft of the literature review.13. Check over the final draft for grammar and punctuation errors.14. Use the checklist provided here to make sure that all parts of the literature review are addressed and focused. REVIEW1. What do you consider to be the most crucial step(s) in the process of your literature review ? Why? Justify your response(s).A literature review can be arranged either topically or chronologically.Topical organization occurs in reviews where previous research being evaluated is divided into segments with each one representing a part of some larger issue. In a topical review, the author begins by describing the characteristics of research shared by several studies and then moves on to analyze their similarities and differences. For more information, see the example below.ExampleThe organization of a literature review begins in the introduction. For example, in the introduction of a literature review about the effect of seating arrangements on peer tutoringcommunication, you would first introduce the topic and what your literature review will attempt to assess:…Writing centers can set the table for collaborative tutoring sessions through a careful consideration of spatial arrangement . . .Then state what angle is going to be explored:…These studies will be used to support the author’s claims that spatial arrangement is instrumental in encouraging collaborative environments in the writing center…Then, arrange key issues that will be addressed in this review by answering questions that you have personally developedand are tailored to fit your topic. In the introduction, give the audience a clear picture of how you will organize your paper: Establishing a Critical Response for a Literature ReviewYou may find this section helpful at Steps 3, 4 and 5 of the process. When reviewing your sources, explore the following areas to help develop your critical response:What is the purpose of the research or work?What research or literary methods are used?How do the major concepts operate?In a research study, how accurate are the measurements?In a literary work, is the author’s position objective or biased? What are the different interpretations of the results of the study or of the literary work itself?M Organization MIn the following, I1 first review some relevant research concerning spatial arrangement and then discuss some recommended and alternate seating arrangements to encourage a collaborative environment in the writing center. Finally, I include some other considerations.In the body of this literature review, you would organize the information topically around each point (or question) that you asked yourself:-Research Review-Recommended Spatial Arrangement-Alternative Spatial Arrangement-Other ConsiderationsThen, write a conclusion that explains the significance of your findings:…While the seating arrangements outlined above are generally a good ‘setting’ for peer tutoring sessions, we should remember that each tutoring session is unique. Not all students will be comfortable with a side-by-side spatial arrangement at a round table. Tutors should be perceptive of and receptive to students who may have other spatial needs…Chronological organization occurs when a review is organized in time order and is most often used when a historical context is needed for discussing a topic from its beginning to its current state; chronological organization is especially helpful when discussing inactive periods and shifts in perspective on a given topic.ExampleThe organization of a literature review begins in the introduction. For example, in the introduction of a literature review entitled Development of Social Science Research on Attitudes Towards Gender in America, you would first introduce the topic and what your review hopes to assess:…This literature review will assess the development of research designed to uncover gender attitudes in America during the latter part of the 20th Century…Then state what angle is going to be explored:..As research progressed throughout the 20th century, the methods that social scientists use for measuring these attitudes developed and changed as well…Then, chronologically arrange issues that will be addressed in this review:Gender stereotypes still exist today, and varying attitudes can be traced over the past fifty years. Survey instruments used to gather data on these varying attitudes have also changed drastically over the course of time.In the body of this literature review, you would organize the information chronologically, adressing each point (or question)that is being asked for a particular time period:-Stereotypes and Survey Instruments of the 1950’s-Stereotypes and Survey Instruments of the 1960’s-Stereotypes and Survey Instruments of the 1970’s-Stereotypes and Survey Instruments of the 1980’s-Stereotypes and Survey Instruments of the 1990’s-Current Advancements1 Always clear the use of I with your instructor. An alternative to this would be the use of third person wording, such as “This paper reviews some relevant research concerning spatial arrangement and then discusses some recommended and alternate seating arrangements to encourage a collaborative environment in the writing center.”Then, write a conclusion that explains the significance of your findings:Although the survey instruments used in the 1950’s and 1960’s developed an obvious bias when surveying Americans regarding gender attitudes, the 1970’s brought about great change. Today social scientists are more careful than ever about testing the quality of a survey instrument before using it on the general public.M Format MThere are also two suggested formats for composing your literature review. Format A is used when comparing several studies that have similar hypothesis but different findings. Each piece of research is summarized individually. Format A is good for reviews with a small number of entries; however, this format may confuse the audience when used with a large number of reviews because descriptions of so many studies may get in the way of the analysis. Keep in mind that each piece of research usually will not receive equal attention in the review.Format A OutlineI. Introduction consists of four parts that are usually discussed in one paragraph.a. Identify the general topic being discussed.b. Mention trends published about the topic.c. State thesis establishing the reason for writing the literaturereview.d. Explain criteria by giving a description of each of the criteria used in evaluating theliterature review and rationalizing its organizationII. Literature reviewed section is divided up according to study.a.First study is summarized and discussed.b.Second study is summarized and discussed.c. Third study is summarized and discussed.III. Comparative analysis acknowledges the similarities and differences between studies.a. Similarities (if any) among the studies are evaluated and discussed.b. Differences (if any) among the studies are evaluated and discussed.IV. Conclusion/Summary effectively wraps up the review.a.Summarize points of comparison or contrast among the works based on Section IIIof your review.b.Provide insight of relationship between the topic of the review and a larger area ofstudy such as a specific discipline or professionFormat B organizes the literature review according to similarities and differences among research rather than by literature studied. In a review organized according to Format B, little background information on the literature being reviewed is given outright. Instead, it is worked into the body paragraphs of the sections on similarities and differences. The conclusion then uses these two sections (similarities and differences) to tie in points of comparison and contrast between the works. Format B better suits papers that are topically organized. Format B is outlined below.Format B OutlineI. Introduction consists of four parts usually discussed in one paragraph.a. Identify the general topic being discussed.b. Mention trends published about the topic.c. State thesis establishing the reason for writing the literaturereview.d. Explain criteria by giving a description of each of the criteria used in evaluating theliterature review and rationalizing its organizationII.Similiarities within the research are discussed.a. First similarity among research is discussed.b. Second similarity among research is discussed.c. Third similiarity among research is discussed.III. Differences in the research are discussed.a.First difference between research is discussedb.Second difference between research is discussedc.Third difference between research is discussedIV. Conclusion/Summarya. Summarize points of comparison or contrast between the works.b. Provide insight into relationship between the topic of the literature and a largerarea of study such as a specific discipline or profession.The most important thing to remember when organizing a literature review is that it is not a list summarizing one work after another. The review should be organized into sections according to theme that are set apart by subject-related headings. REVIEW1.Which format have you chosen for your literature review?

literaturereview-英语文献综述-写作技巧LITERATURE REVIEWThe literature review presents one of the greatest challenges of the research proposal to experienced and inexperienced researchers alike. The literature review:m Provides a conceptual framework for the reader so that the research question and methodology can be better understood.m Demonstrates to the expert reader that the researcher is aware of the breadth and diversity of literature that relates to the research question.It is important that you are able to provide an integrated overview of your field of study. This means that you show awareness of the most important and relevant theories, models, studies, and methodologies. You should indicate how these are relevant to your project, and how these works are similar to and/or different from your own research. The literature review is not simply a list or summary of books and articles that the researcher has read. Instead, it combines the most significant aspects of the works you have consulted, combining and synthesizing them in an integrated description of the field of study.A good literature review shows how the texts you have mentioned relate to the broad topic, as well as showing the expert reader that you have surveyed much of the appropriate literature. It also demonstrates that a number of different approaches - or ways of understanding - the material will be used, and, in combination, will help you to produce an original study.If you are having difficulty with this section, try structuring your work around these questions:m What are the broad bodies of literature that have relevance for your research topic (local and international)?m What methods and results have previous researchers in your field produced? What is the history of your area of study?m What theoretical model, or models, relate to your research topic? Describe these in detail.m What different methodologies have been used by other researchers in your area? Try to identify the key methodological issues that must be addressed, since these will determine your own choice of methodology.m What are the most recent research findings in your area of study?m What gaps and contradictions exist among these findings?What new research questions do these findings suggest?m What structure suits my literature review best?m What should I leave out?m What quotations should I include?Examples: (The research topic is "the History of Mental Illness in Natal in the period up to 1945")Unsuccessful Literature ReviewFoucault's works looked at mental illness, asylums, and the archaeology of knowledge. Roy Porter and Edward Shorter's histories of psychiatry and psychology show that definitions of mental illness have differed across time and place. Ernst andSwartz record that under colonialism science andmedicine contributed to racial, class, and sexualdiscrimination.Feminist writers Chesler and Showalter who have written on psychiatry will be important for this study. Post-structuralist and post-modernist approaches to theconstruction and representation of identities will be used.Post-colonialism's concern with the 'subaltern' and thesuppression of 'subaltern voices' will be significant.Successful Literature ReviewThis study will draw on diverse approaches to the history of psychiatry, and to the origins of segregation in southern Africa. Histories of psychiatry and psychology have shown that, although having a probable partial biochemical basis, the criteria for the definition of mental illness have differed across time and place. The history of science and medicine in both Europe and in the colonial order provide a means for exploring the role of biomedicine (including psychiatry) in contributing to racial, class, and sexual discrimination.Feminist analyses of the centrality of gender, and critiques of psychiatry and psychology, will be a key axis around which this study is formed. For example, while men of all races formed the majority of inmates at the Natal Government Asylum in nineteenth century Natal, women were deemed to be particularly prone to particular forms of mental illness.Post-structuralist and post-modernist approaches to the construction and representation of identities, and to the articulation of power, will provide a means of deconstructing the 'texts' and discourses which are an important part of this study. In particular, the works of Michel Foucault on mental illness,asylums, and the archaeology of knowledge will be considered. I recognise, however, that the application of Foucault's ideas in the African context is problematic. Post-colonialism's concern with the 'subaltern' and the suppression of 'subaltern voices' will be reflected in attempts to 'hear the voices' of the institutionalised.。

A Literature Review of An Empirical Study ofMultimodal Teaching Model inMiddle School English Listening Teaching in a Multimedia ContextIn recent years, the theories of multimodal discourse and multimodality have gained many scholars’attention。
Many researchers study them and try to apply multimodal teaching to middle school s’ teaching。
And nowadays，many famous language scholars are trying their best to do the empirical study on the multimodal teaching。
As a matter of fact, many noted researchers have made a brief definition of multimodality. “M ultimodality means the combination of different semiotic modes—--for example, language and music—-—in a communicative artifact or event” (Kress ＆Leeuwen 1996：281)。
“M ultimodality refers to the diverse ways in which a number of distinct semiotic resource system are both codeployed and cocontextualized in the making of a text—specific meaning”(Baldry ＆Thibault 2006：21).Since the 1990s of last century, the multimodal teaching approach has drawn the researchers’and the teachers' attention in abroad。

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.。
Literature Review (Sample 1)文献综述
Literature ReviewC12 英语〔1〕 X X XTess of the D’Urbervilles is generally regarded as Tomas Hardy’s finest novel. Since its publication in 1891, it has encountered considerable concern in literary criticism. Among these numerous essays dwelling on Tess, most criticisms and interpretations focus on probing into the root of Tess’s tragedy. These scholars ponder Tess’s tr agedy from various perspectives and give a multitude of interpretations on this topic. But no one can exhaust such a great work，there is still much room for further consideration about Tess’s tragedy. Through several months’ efforts in searching, collectin g and reading an abundance of scholars and professors’ literature concerning causes of tragedy of Tess, I have learned much and gained a lot of data and create the following essay which summons up the essence of the literature.1．Analyses of Objective F actors in Tess’s Tragedy.The Age Characteristic and the Rebel in Tess of the D’U rbervilles – A Feminine Decoding on Tess of the D’U rbervilles by Jiang Lu introduces the economic background of the story. Jiang states that the story of Tess happened during the late half of 19th century, which witnessed the decline and destruction of the English peasantry. It was an age of transition and great social upheavals. With the development of capitalism, England was slowly developing from its former state of a mainly agricultural country to its new condition of a primarily industrial society, because of which the traditional self-sufficient society order in the country was broken. Helplessly confronted with the change, the country villagers were deprived of their lands, houses and other possessions. Then, in possession of few things they were forced to immigrate away from their accustomed land and to be employed as farm workers. Therefore, country peasants were inflicted tragically by the industrial development. This part clearly demonstrates the economic situation of the farmer at Victorian age which is quite beneficial to my paper.An Ecofeminist Reading of Thomas Hardy’s Tess of the D’Urbervilles by YuKun discusses the tragedy of Tess from the perspective of Ecofeminism, this paper practically explores the close relationship between women and nature and women’s tragic fate as the result of industrialization and patriarchal society, which helps me understand Tess’s tragedy from a new angle. It points out that at the late Victorian Age when industrialization began to encroach upon the countryside rapidly and capitalism developed further, the peasants lost their land and many of them were impoverished. Tess’s family,without exception, was poverty-stricken, which turned out to be the very root of her tragedy. Tess, impelled by the economic pressure from her family, had to go to claim kindred with prosperous D’Urbervilles family where she met evil Alec who deprived of her virginity; and it was her poor family that made Tess return to Alec. Besides, the society in the Victorian period was a man-dominated society, woman had to suffer the injustices of man-made law, the law by which man and woman were not equally treated in terms of morality. Angel who set a double moral standard for man and woman certainly couldn’t conceive of a relationship of equality with Tess. He couldn’t forgive Tess for her lost of virginity although he himself had dissipated past. Thus he finally abandoned Tess because of her “impurity〞, which gave Tess a fatal blow.The Connotation and Characteristic of “Angels in House〞in Victorian Period of England by Zeng Yayin demonstrates perfect women’s image in people’s mind in Victorian period. It says that a traditional Victorian woman is supposed to be a perfect woman. First, they should be gentle, graceful and charming, that is to keep an attractive appearance. Second, they should be submissive. They were taught to be sympathetic, gentle and considerable to other people. And the most important thing was to be submissive to their father or brothers, and after being married, their submission turned to their husbands. Third, they should have pure bodies. Traditionally, virginity was worshipped as a symbol of honor for an unmarried woman. It was very important for a younger woman to be a virgin before marriage and be loyal to her husband after she married him, and virginity was a girl’s virtue and value as well. Fourth, home was her whole world. She should sacrifice herself for her husband and the family. Taking care of the family and making the home healthy andcomfortable was undoubtedly all her duty. Besides, they were economically dependent, what they should do was to stay at home which was the shelter for them, and to seek for support and protection from them, so marriage was pretty much their best choice. All in all, the idle Victorian woman should be devoted, pure both mentally and physically and submissive. This paper gives me a general idea of the image of women in Victorian period, which will help me a lot in my paper.Analysis of Tragedy of Tess by Tang Xuan points out that Tess is a typical female tragedy, considering the convention and the bourgeois morality of her time. The last years of the nineteenth century were the Victorian period. Victorian morality imposed rigid norm on women, which demanded women to be pure. The loss of virginity was a fatal blow to Tess as she was turned against and crushed by the social convention. It was a man-dominated society, in which woman had to suffer the injustices of man-made law, the law by which man and woman were not equally treated in terms of morality and the use of double standard in sexual matters was the essential feature of the Victorian society. This was why Tess, being violated by Alec, unfairly suffered from being morally and socially spurned and punished while Alec remained free from any social reprimands. What is more, according to the Victorian customs, a man could live a dissipating life as he had once done while a woman could not. This double standard for man and woman made it impossible for Angel who was dominated by the conventional social custom and the bourgeois view of morality to forgive Tess. This part helps get a better idea of the impact of social convention and morality on Tess’s tragedy.The Ruin of a Pure Woman — Analyses of the Tragedy of Tess by Zhou Hong says that Tess is the victim of capitalist law and hypocritical religion. It states that Alec dared to do evil at his pleasure not only because he was a man of money and power, but also because he was under the protection of bourgeois law which was employed as a tool to rule ordinary people and was always at bourgeois’ interest. According to the law, it was ironic that the man who seduced Tess was justified while Tess who suffered damage was sinful. Oppressed by so strong social prejudice, Tess was deprived of the right to protect herself and forced to accept the unfair treatmentimposed on her. Thus, she was doomed to be a victim of power and violence. Besides, hypocritical religion was also closely related to Tess’s tragedy. In capitalis t society, religion was just used as a tool to lull and enslave people. When Tess met Alec again, to Tess’s as tonishment , Alec, the man who seduced her and ruthlessly pushed her into the abyss of tragedy, could resort to Christianity and became a priest who asked people to do good deeds. From this part I can see that both bourgeois law and religion are hypocritical.2. Reflection on Subjective F actors in Tess’s Tragedy.Analysis of Tess’s Character by Xu Haibo focuses on Tess’s character to explain the cause of Tess’s tragedy. It points out that the character of Tess is closely related to her fate, it is the tension in her character that leads her to the tragedy. The most obvious ones are those between humility and pride, and between innocence and sensuality. Ultimately it can be said that the tension is the one between obedience and rebellion within her character. It presents that both historical conditions and living environment contribute to the formation of Tess’s character. Tess has the qualities of kindness, honesty, diligence and loyalty which are shared by the label people, besides, she also inherits the pride traditionally associated with noble families, but her pride is conflicted with her social and economic position. In this paper, the author gives a detailed explanation with examples about the tension in Tess’s character which helps me better understand his idea. Besides it points out that there is also conflict between acquired conventional belief and instinctive independence of mind, and between ignorance and education in Tess’s character, which can also be seen from many cases. From this article, I get a good knowledge of Tess’s character as well as its relationship with her fate.Study on the Tragic Fate of Tess by Zhou Zhongxin and Wang Yanwen points out that Tess is a pure woman, but, ironically, her purity becomes the decisive factor of her tragedy. It states that Tess’s pure nature is fully embodied by her strong sense of responsibility and self -sacrifice to her family. When their horse is killed in an unexpected accident, nobody blames Tess as she blames herself, therefore, she doesn’trefuse once more her parent’s suggestion to claim kin with the wealthy D’Urbervilles family although she is not willing to do so. This is the very action that ruins all her life, she is seduced by Alec and later gives birth to an illegitimate baby. Moreover, her sense of responsibility is also clearly revealed when she becomes a mistress of Alec because of the desperate situation of her family. Tess’s purity is also displayed in her honesty and loyalty to love. When she is seduced by Alec, she bravely chooses to leave him at once irrespective of the pressure of her family and the society, because she realizes that she has never loved Alec.As to Angle, she falls in love with him deeply, but she continuously refuses Angle’s wooing because she thinks her being his wife is a shame for him. In order to protect Angle, she is willing to sacrifice her own feeling and happiness. Although she accepts Angle at last, she decides to disclose her past to him because of her honesty and true love for Angle. But her confession only results in an end of their marriage, she is deserted by her heartless husband, which leads to her miserable life soon afterwards. This paper offers me a good idea of the relationship be tween Tess’s purity and her tragedy.A Multi Perspective of the Tragedy of Tess of the D’Urbervil les by PengYan mentions the persecution of religion on Tess. Brought up in a heavily religious environment, Tess is deeply poisoned by religious thought, which forces Tess to bear enormous psychological pressure and induces her to sink into tragical abyss. Tess is a victim of religious doctrine. When her baby is dying, she suddenly realizes that she hasn’t been baptized and therefore will die without salvation a nd go to hell, but no parson is willing to do it for her baby, so she decides to baptize her baby by herself. Obviously, all her terrors about the hell are coming from the religious doctrine taught to her. Besides, although she used to doubt the existence of God when she feels desperate toward life, she can’t free herself from the shadow of religion. She always uses religious thought to imagine, explain and symbolize her miserable life. When she meets a man writing biblical texts on walls, she consciously feels ashamed and guilty for her loss of virginity, although it is not her fault. She is always self-contempt and keeps torturing herself by hypocritical religion thought. From this part I get to know religion’s impact on Tess.My Opinion about Tess of the D’Urbervilles by Li Honglan points out her family’s role in causing her tragedy. It says that Tess’s parents are ignoran t and vain，which leads directly to Tess’s tragedy. Tess’s father, Jack is lazy, selfish and foolish. When he hears of the news about his noble ancestry, he thinks his family will surely become rich if only Tess go to claim kinship with the wealthy family. When Tess is seduced by Alec, he doesn’t care about his daughter’s feelings and lock the door to prevent Tess from going out, the only thing that worries him is what others will think of this collapse of his family pride.Besides, Tess’s mother Joan is no better than Jack. The news of ancestry also affects her, she wants her daughter to rise in the world by making a successful marriage and thus bring fortunes to the whole family. When Tess chooses to leave Alec, she blames Tess for not marrying him and when Tess is deserted by Angle, she thinks it is all Tess’s fault. At the same time, her father doesn’t show sympathy for Tess either, he even doubts about her marriage, which makes Tess unable to live at home any more. Since her parents cannot be relied on, Tess takes on her younger shoulder the family burdens. She has a strong sense of responsibility towards her family and at almost every stage of her life it is her concern for family that influences her actions-from her agreement to claim kinship to family D’Urberville right to her final decision to return to Alec is totally due to her responsibility to support her family. From this analysis, I get a comprehensive knowledge about the influence of Tess’s family on her tragedy.Tess一A Pure but Tragic Woman by Zhang Qun discusses the influence of two men —Alec and Angle on Tess’s tragedy. It explains that Alec, typical of a bourgeois villain, m etamorphoses himself into the more dignified style of Alec D’Urberville and decorates himself as a man of nice heart. He takes advantage of Tess’s poverty and innocence, and seduces her on purpose. Thus , Tess intends to look for a way out but is driven by him to a way with a dead end. On the other hand, Angle is a representative of bourgeois intellectuals. He regards himself as a man full of new thoughts who isn’t bound by social customs. However, as a matter of fact, he couldn’t free himself from it. He idealizes Tess as symbol of purity and pursues her enthusiasticaly, but desert her as soon as Tess’s confession. Given up by her husband,Tess can’t support her family on her own and she is foeced by the death of her father and consequent loss of their cottage to succumbe to Alec to be his mistress. But out of her expection, Angle comes back, she is so shocked and regretfull that she kills Alec, because she thinks it is the only way out. From this analysis, I get a sense of these two men’s impact on Tess and I will use some of his idea in my paper.3. Introduction to the A uthor’s Outlook Reflected in the Novel.On Fatalism and Pessimistic View in Thomas Hardy’s Tess of the D’Urbervilles by Hu Ye says that Tess’s t raged y is related to Thomas Hardy’s fatalisti c outlook on life. Tess’s life can be divided into several stages and every stage is sprinkled a series of coincidences that push Tess to the doomed abyss. In this paper, it gives details about these coincides. At the outset, Tess’s father John Durbeyfield is so excited at the news of her ancestor that he drink himself drunk, so Tess has to replace her father to send the beehives to the market. Then the accidental death of the horse Prince destroys the family’s livelihood, so Tess is forced to go to claim k in with the wealthy D’Urbervilles family, where she is seduced by Alec.After this great frustration, she happens to meets Angle and falls in love with him. When she is about to marry him, Tess decides to write her past in a letter and thrusts it from unde r the door into Angel’s bedroom. But the paper gets mislaid under the carpet and Angel does not see it, which directly leads to the break of their marriage. When Tess eventually decides to visit Angel’s parents and asks them for help, she unfortunately ove rhears the conversation of Angel’s brothers, then she give up asking help from them. There is also the coincidence that she reencounters with Alec at exactly the moment when she is most vulnerable, then she becomes her mistress. Considering these coincides, I think that there is close relationship between Tess’s tragedy and these coincidences, although they all happen by chance.Tragic Consciousness Inherited and Future Developed in Hardy’s Novels On The Tragical ness in Tess of D’Urbervilles and Jude the Obscure by Zuo Yanru says that Thomas Hardy is an inheritor of classical tragedy, so he naturally transplanting the ideas of fatalism into his tragedy novels, and Tess of the D’Urbervilles is a typicalone. It tells that Hardy’s perspective of fatalism ha s two distinctive features. First, his fatalism often arises from the external environment, both social and physical, and the internal character of the protagonists. This realistic concern is a new aspect of fatalism. Second, in order to achieve the desire d tragic effect, Hardy’s destructive forces are reflected as the combination of accidents and inevitabilities, which aims to produce a strong sense of fate. The two features makes Hardy’s novels produce a strong sense of fatalism. This introduction lets me know the character of Hardy’s fatalism and its influence on the novel.Having read the above literature concerning the analyses of Tess’s tragedy, we have no difficulty to find that more and more scholars and professors both at home and abroad begin to p ay attention to the field of the cause of Tess’s tragedy. Most of them probe into this field from the perspective of social background, the heroine’s inner factors or the heroes destructive impact, there are not many other interpretations, however, all of them give me good guide to this topic and help me gain a better understanding of various elements relating to Tess’ tragedy, it also evokes my interest towards this topic and stimulates me to study this topic from a new perspective. In my paper, I tend to analyze the tragedy of Tess from individual choices with the help of the achievements of the critical study done by the former Hardy scholars, and I hope that I can make some contribution to this field by reading extensively and analyzing the literature.ReferencesXu Haibo.

文献综述literaturereview
英语学术论文之文献综述1.文献综述的基本认知1.1文献综述的概念“综”是要求对文献资料进行综合分析、归纳整理，使材料更精练明确、更有逻辑层次；“述”就是要求对综合整理后的文献进行比较专门的、全面的、深入的、系统的评述。
简言之，文献综述是对某一方面的专题搜集大量情报资料后，经过综合分析而写成的一种学术论文。
详细理解，如下所示：①基础：大量搜集某一研究领域或专题文献的资料② 加工：对国内外在该领域或专题的主要研究成果、最新进展、研究动态、前沿问题等进行综合分析、分析、归纳、整理和评述③ 生成：生成比较全面的反映相关领域或专题历史背景、前人工作、争论焦点、研究现状和发展前景的论文。
1.2文献综述的特征1.内容的综合 : 这是文献综述最基本的特点 , 包含两方面的含义。
一方面 ,文献综述首先表现出对大量文献的综合描述。
各种类型的综述, 其基础都是综合叙述。
“必须将每一篇需综述的原始文献置于上下文里, 并用某一方面的知识对其进行分析和综合”。
另一方面 , 它综述广泛时空范围内的发展和情况, 既有纵向描述 , 又有横向覆盖。
2.语言的概括 : 文献综述对原始文献中的各类理论、观点、方法的叙述不是简单地照抄或摘录 , 而是在理解原文的基础上 , 用简洁、精炼的语言将其概括出来。
因此文献综述不同于文摘 , 不是将原文献的中心内容摘录出来 ; 也不同于节录 , 不必完全按照原文节选下来。
而是将文献中有用的理论、观点和方法用最精炼的语言加以概括的描述 , 提炼出数据 , 同时舍弃原始文献中的论证、计算、推导过程等细节。
3.信息的浓缩 : 文献综述集中反映一定时期内一批文献的内容 , 浓缩大量信息。
一篇综述可以反映几十至上百篇的原始文献 , 信息密度大。
关于一篇综述需要有多少参考文献, 国内外的学者们都做过不少研究, 有一些不同的意见。
评价综述文献的压缩程度可用综述文献正文每页所引用的参考书目平均数或者是被综述的原始文献页数与综述文献页数之比来考察。

功能对等理论谈E.B.Whites散文汉译中的风格对等The Style Equivalence in the Translation of Essays by E.B.White Based on the Theoryof Functional EquivalenceNo one can deny the difficulties in the literary prose translation from English to Chinese. And essay, generally can be seen as literary prose, with its huge varieties in form, content, and style etc., is hard to single out the translation of it as a whole for evaluation. Discussions surround the translation of essay never die. Scholars, home and aboard, have done a great body of researches on it, some of them stand out for their original and comprehensive achievements. Now let’s have a check on some extraordinary theories in essay translation built by them.First comes Hilaire Belloc, he points out that the essence of translating is the resurrection of an alien thing in a native body, which has something of the opinion of “reaching the acme of perfection” by Mr. Qian Zhongshu in his work On the translation by Lin Shu, and laid down six general rules for prose translation, which give relative clear guidance for the translation of prose text.Then Burton Raffel, argues, in his book The Art of Translating Prose, that the strict translation of prose should reveal the inner structure of the original syntax. In his opinion, the syntactic structures of prose represent the style of the author, and “the style is the man”. And he further puts forward that only when the syntactic structures of the original message is kept or retained, can the style of the original be successfully reproduced or transposed. He takes translation as an art rather than a science, and views the prose translation more from the perspective of stylistics.As for domestic scholars on the studies of essay translation, Professor Gao Jin holds the idea that the tone and style are to a large extent translatable, and gives definitions for the translatableness of language in general and translability in particular cases. And if the essence of the thought and idea of the original are fully grasped, tone and style of author are likely to be retained.And Liu Shicong with its “artistic flavor” theory. According to Professor Liu, the “artistic flavor” contains textual atmosphere, sound and rhythm, individualized artistic recreation. He reaches to a deep level of prose translation with the recreation of the artistic flavor as the very core. While his theory is hard to operate, and stands the test of time.Among all the theories, Functional equivalence theory is of highest importance. The Functional equivalence, originally called dynamic equivalence, raised by Dr. Eugene A.Nida as “the closest natural equivalence” of the source language text, is taken as a better and relative operative way to evaluate and handle problems in translation, that the traditional translation theory cannot well manage. Before the theory came, there is no practical method of keeping balance between literary translation and free translation. Though it is not straightly stick to prose translation, it still guides a lot to the translation of essay.This paper tries to analyse the equivalence of style in the translation of essay based on the Functional equivalence theory, taking some essays by E.B.White for example.。

Literature+Review（精选五篇）
Literature+Review（精选五篇）第一篇：Literature+Review什么是Literature Review？Literature Review 就是回顾总结过去所发生的事，回顾总结前人所写的文献。
Literature Review通常出现在毕业论文里面的第一部分。
为什么写Literature Review？写Literature Review的目的，就是为了通过回顾前人所做的研究和文献，来确定自己毕业论文的研究方向（确保自己的论文是研究出新的成果，做出新的贡献，而不是重复前人研究出来的东西，比如说，1+1=2，这个就没必要研究了，之前已经有无数人反复研究过，并验证过了）。
而且在论文里面写Literature Review，是为了让阅读的人对这篇毕业论文有一个大体的了解。
怎么写Literature Review？在Literature Review里面，主要是总结前人的文献，和过去发生的事。
这就需要阅读很多之前的资料。
一定是要写总结，很多学生只是把以前的资料在Literature Review里复述一遍，是不行的。
而且，Literature Review千万不能得出结论，比如说，你的毕业论文是调查有钱人家庭的学生成绩好，还是穷人家庭的学生成绩好，Literature Review就是要写总结之前各个学者做的研究，新闻的报道，为什么有些学者觉得有钱人家庭的学生成绩好，或有些学者觉得穷人家庭的学生成绩好，两面性都要总结出来，之后你下一部分的分析（Findings Analysis），也就是你这篇毕业论文的成果，才是你要得出的结论：有钱人家庭的学生成绩好，或是穷人家庭的学生成绩好。
所以说，选研究题目也是很重要，要找一些两面性的，还没能得出结论的，少人研究的研究题目。
没什么好研究的题材，做出来的也不是什么好毕业论文，比如说，宇宙有没有太阳。
今天就说这么多，下次继续说其他的吧。
