Poes Fall of The House of Usher Essay: Beyond Empiricism and Transcend

Beyond Empiricism and Transcendentalism in House of Usher      Ã‚   When Edgar Allan Poe wrote "The Fall of the House of Usher," two factors greatly influenced his writing. A first influence was John Locke's idea of Empiricism, which was the idea that all knowledge was gained by experiences, exclusively through the senses. A second vital influence was Transcendentalism, which was a reaction to Empiricism.   While John Locke believed that reality or truth was constituted by the material world and by the senses, Transcendentalists believed that reality and truth exist within the spiritual or ideal world. They believed that the external world was dependent solely on the conscious. Beverly Voloshin suggests that "Poe presents transcendental projects which threaten to proceed downward rather than upward" (19). Here it becomes obvious that there is a strong connection between John Locke's Empiricism and the resulting ideas of Transcendence, and the powerful effect that they had on Poe and other emerging Romantic writers of that time. In "The Fal l of the House of Usher," Poe establishes a new type of literature, one that emphasizes aspects of Empiricism as well as the idea of Transcendence. Poe uses this unique literature to introduce the Usher mansion and its intriguing and very troubled inhabitants.    Locke wrote the "Essay Concerning Human Understanding," which was published in 1690, and is credited with opening up the period of Enlightenment in Europe.   Its strongest connection to Poe was that it had a   "late popularity in New England"(Voloshin 18). With this popularity in New England, many of the writers of the time either voiced their approval of Empiricism, or took an opposite stance in their literature. Locke believed th... ...an upward. "The tales have a paradoxical structure in which transcendence is figured as an outward or downward movement, as the method for going beyond the universe of Lockean empiricism is to go through it" (Voloshin 19).   Poe brings this out with the narrator's "depression" and the "unredeemed dreariness of thought."   The language that is used in "The Fall of the House of Usher" presents a connection between the mental and the physical world, which then correlates with the debate between Transcendentalists and the empiricism presented nearly two centuries before.       Works Cited Koster, Donald N.

Briefly comment on the communication research report Essay

With rapid advancement of new communication technologies, people currently can freely and actively express their own opinions in the new media. For example, the Internet has dramatically changed the ways in which some individuals receive news and information, this is very big different from the traditional forms of communication. However, there are some correlation links between traditional mass communication ways and modern new technology ways(Kotcher,1992;Rubin, 1994). Roberts M, Wanta, W and Dzwo, T (2002) examined one aspect of the Internet: electronic bulletin boards (EBBs). The objective of this study is to investigate if traditional news media sources have an agenda-setting impact on the discussions taking place on the EBBs. In other words, the purpose of the study is to examine the agenda-setting process and the role it may play on the Internet. The report’s dominant methodology is quantitative. As we know, it is a critical issue that appropriate methodology should be taken depending on different research topic. Quantitative approach and qualitative approach have their respective advantages and disadvantages (Fowler, 1993). Quantitative research, through surveys, gathers data about people’s knowledge, opinions, attitudes and behavior. Quantitative research approach is used to generate new knowledge for evidence-based practice. Attention will be given to the advantages and disadvantages of Quantitative research designs for large group research, the principles of reliability and validity, the value of descriptive and inferential statistics and the importance of ethical research conduct. For the topic, it belongs to sociology category, so I think the researchers have used appropriate research approach (quantitative research approach) even though the approach has some disadvantages. This is because quantitative research approach for this topic has the following advantages: Large members of people can be studies; the method is relatively quick and relatively cheap; the results are reliable, and representative of a much wider population than that directly investigated, the personal influence of the research on the results is slight and the data can easily be expressed in statistical form. This enables comparisons to be made between different groups and populations. For this study, the researchers use Internet, its main advantages are low/moderate cost to design; low cost to send; quick to analyse data; easy for respondent to complete and can attach brochures, images, etc. However, Every survey methodology has its weaknesses, and online surveys are no exception. – Not sure who is answering the survey. Like mail studies, it is difficult to insure the desired person actually answers the survey. – Not representative of the population. The Internet population has a slight bias towards younger, more computer literate users, though this is changing all the time and becoming more representative of the population. – Long surveys are more difficult. The personalities of today’s online users makes it difficult to coerce respondents into completing long surveys. – Not a â€Å"mainstream† research methodology, yet. With more experience and comparative analyses of online surveys versus mail and telephone results, online surveys should reach the same level of acceptance as other methodologies. For this research, the researchers use EBBs which has the above weaknesses too. For the research’s method, the researchers use five steps (Roberts, 2002, P456-458): The first step imperative examines whether traditional news media sources have an agenda-setting impact on the discussions taking place on the EBBs. They ask † Do individuals take issue information gained from news media and pass information about this issue online to other electronic bulletin board users? † The second step is selecting the sample. The third step deals with defining categories, time frames, coding units, and context units. The fourth step is content analysis and the final and fifth step of content analysis process is to analyze and interpret the data. The five steps are typical research method that is used by many researchers (McMillan, 2000) and they are very similar with the quantities analysis approach (the Scientific Method) which includes seven steps: Defining the problem; Developing a Model; Acquiring Input Data; Developing a Solution; Testing the Solution; Analyzing the Results and Implementing the Results (Render, 1982). The researchers use an ARIMA model cross-correlational test showed EBB discussions of three issues—immigration, health care, and taxes-correlated with news media coverage, with time lags varying from 1 day to 7 days. In my opinion, the method is appropriate method for the topic. This investigation looks for a more powerful effect than previous agenda-setting researchers. Because of the Internet’s dynamic characteristic of transmitting information from senders to receivers, researchers currently assume that our traditional theories of mass communication can directly apply to online communication (Wimmer, 1994). The researches have an accurate research questions or hypothesis that are: how will the new online communication forms affect the agenda-setting process? Can we assume that the transfer of salience still follows the original hypothesis? How does the condensed and compressed environment of online communication affect what we know about time frame effects? All these questions are explored in their study. By quantitative research, the researchers concluded: † The results demonstrate the usefulness of examining the rule the Internet plays in the agenda-setting process. Media coverage apparently can provide individuals with information to use in their Internet discussions. As the Internet continues to become an important source of information, it also will become an important area for mass communication researchers. † (Roberts, 2002, P464). The report also recommended† future research should link other mass communication theoretical approaches with Internet usage†. Despite the research has some definite problems; online research has many more advantages than disadvantages. When surveying populations, which mimic the demographics of online users, online research can be a primary means of information collection. With other populations, online research can be effective as a supplement to more traditional survey approaches or as a quick impression of your customers (much like qualitative approaches are used). For outlook, as the Internet continues to grow in popularity, investigations of the content of information being sent online similarly will increase in importance. The study takes an important step in linking the Internet to a mainstream mass communication theory. References Kotcher, R. L. (1992).

Some people are happy with a small amount of money with comfortable living while others want to earn large amounts of money and become rich. However, living with less is like having minimalist lifestyle which involves material limitations, less consumption, more space, less unnecessary possessions and so on.Furthermore, as Graham Hill (2013) entrepreneur and founder of LifeEduited. com and TreeHugger. com reports, â€Å"I sleep better knowing I’m not using more resources than I need. I have less and enjoy more† (n. p) (as cited on www. nytimes. com). Living with less brings appreciably more satisfaction, relaxation and enjoyment. Moreo ver, people will not get attached to things. For one thing, people who depend on their possessions and luxury life, in many cases lose part of life that is really important. The minimalist lifestyle in U.S is a beneficial way to allow pleasure and better health and spending less time on new technologies but on the other hand people get losing this knowledge of modern society of this country. One of the advantages of living with less in U. S is that people can take more joy and time. Living with fewer possessions is not only having joy but also is very closely related to the times and technology. The fewer possessions you have to worry about, the more time you have to spend with friends, family or in nature or beautiful places in life. Technology is incredible and infinitely developing, but occupies most of our time.For example: social technology provides the ability to connect, communicate and also play games and others. As Albert Einstein who theoretical physicist and one of the fo unders of modern theoretical physics (1921) demonstrated, â€Å"It has become appallingly obvious that our technology has exceeded our humanity†. (n. p) However, one should note here that technologies can take away a large part of the time of your life. If on the one hand it can be said that it is beneficial having enjoyment and more time, the same is true for better health.Another beneficial advantage of living with reducing possessions in the United States is that people feel less stress. Living with less material stuff allows people the ability to not worry about their obligations. Therefore, living with fewer possessions allows less worrying about obligations which includes cleaning, repairing, breaking, and obsolete of these materials. Material objects not only lead to physical fatigue but disorders like depression too. As American Psychiatric Association (2011) shows, â€Å"depression is a common and highly treatable disorder affection over 17 million American adults a nnually† (n. ). It is generally agreed that stress and nervous feelings brings a negative effect on disorders. With living with less stuff, you can avoid depression and aggression by obligations of items. Another way of looking to this lifestyle, it is about surplus of knowledge of new technologies. One of the unbeneficial ways of living with less is that using less modern technologies. For instance, if people stick to this way of life, and they prefer not to use the new technologies, gadgets and other things, it will be bad influence on the formation of person as a modern one.Many people will consider as a primitive man who is absolutely nothing know, it is difficult to have a dialogue with someone who cannot understand what others mean. Likewise, as Jonas Salk who was an American medical researcher and virologist (1979) shows, â€Å"This is perhaps the most beautiful time in human history; it is really pregnant with all kinds of creative possibilities made possible by scien ce and technology which now constitute the slave of man – if man is not enslaved by it†(n. p) . In reality, all technologies are developing that is why future without him nothing would do.The most importantly is that being a successful person makes a big influence on the skill of modern technology not only for work but also for self-improvement. One should, however, not forget that if people have lack of knowledge of new technologies, in many cases, they can’t find perspective job to successful career. Our modern world is difficult to imagine with lack of knowledge of computer technology, and successful professional worker without this knowledge. The United States is one of the most highly developed states in the world that is why new technological hings have an important part of their life. A minimalist lifestyle offers the enormous benefits and if Americans want to take more joy and time and feel less stress, they need to start living with less. As Julie Schor who is a professor of Sociology at Boston College (2002) shows, â€Å"we need to invest more meaning into material objects to slow down the buy-use-discard cycle of U. S. consumer goods†(p45-60). This means, society of this country should really think about material possessions, whether want to buy it, whether it is beneficial or useful etc.

Lost In Translation Vietnam A Combat Advisor’s Story

Lost In Translation: Vietnam: A Combat Advisor's Story is a very well-known book, which was penned down by Martin J. Dockery. The author of the book has presented a very well-documented account of the experiences of a young officer’s which he encountered during the early years of America’s Vietnam War. This is a description of the time when President Kennedy had sent hundreds and thousands of advisors to Vietnam in order to teach the South Vietnamese Army the ways to fight their war. The author has basically presented the history of American military. The book is fairly enjoyable and informative at the same time. The author of the book, that is, Martin J. Dockery was one of the advisors that were sent by President Kennedy to Saigon. Initially he was a very strong-minded, idealistic first lieutenant of the Army of the United States of America. When he arrived at Saigon, Dockery was certain of America’s coming up victory in Vietnam. A vast number of in-country military advisors of the United States of America filled basic support positions in Saigon and other major cities of Vietnam, Dockery was one of the few advisors who had been assigned Army of the Republic of Vietnam (ARVN) combat units. Dockery lived with and fought with an ARVN infantry battalion in the Mekong Delta for nearly eight months during which they carried out missions and operations that usually lasted for a number of days. Dockery here was the single American soldier in the entire unit and most of their time was spent traipsing all the way through the sweltering jungle which was infested by leeches, hiking across canals, or getting involved in unexpected firefights. This stay with the ARVN right in the beginning of the American participation in Southeast Asia provided Dockery with a chance to understand Vietnam far more better than any of the other Americans.   Through this book, the author has gained attention towards the chiefly disregarded part of American combat advisors in the war. By the use of sounds, smells and the view of the country as well as its people, Dockery has put forward the image of an army that was not properly trained, was ineffectual, and reluctant to fight for a government, which was perhaps as corrupt as the French colonial empire which it had replaced. But, for Dockery, his seclusion, threat and annoyance were nothing as compared to his emergent certainty that the advisory program was prone to turn out as a disaster. He believed that even though the advisors would work to their best and that too under the most difficult situation, they would not be able to succeed in the war. Basically, through this book the author has tried to tell us about the reasons which were the cause of the American failure in Vietnam. These causes range from the arrogance of the American views of people and culture to the complete misapprehension of the Americans regarding the influence of the dead on a culture. Through this book, the author has depicted the transformation of his preliminary zest and optimism into discontent with the responsibility that was laid down upon him by his government. The experiences of the author are extremely absorbing, but the most insightful experiences are those which he encountered during his encounters with the hosts of Vietnam regarding the cultural differences. His expression of the social values and the traditions of the Vietnamese people are extremely emotional and touching. Book Report As mentioned above, Lost In Translation: Vietnam: A Combat Advisor’s Story by Martin J. Dockery is a very well-known which was written by the author in order to raise awareness regarding the causes of the loss suffered by the Americans in the Vietnam war. Right in the beginning of the book the author writes, â€Å"This book is not a scholarly work or a comprehensive history. There are no footnotes. It is a memoir based primarily on my recollection of events that occurred when I was a combat advisor in Vietnam in 1962-63. It is only my story† (Dockery, Acknowledgements). Clearly this book is just his memoir, but it has raised much awareness and has unfolded the mistakes of the American government and the military. Further on he says, â€Å"next to the birth of my sons, Vietnam has been the defining experience of my life; it has impacted me profoundly. Not a day goes by when I do not think about Vietnam and my experiences there. Even now I recollect with clarity the sounds, smells and vistas of that place and its people. My tour of duty in Vietnam was marked by isolation, frustration and danger. Nevertheless Vietnam transported me. This is primarily an account of my assignment as a combat advisor to a South Vietnamese infantry battalion. It is an old tale from an old war, but I think it is relevant and instructive today† (Dockery, Preface). This opening statement basically clears out the fact that the book was written in order to inform us of the wrong doings of the American military and government, but when we look closely as the statement it shows how much the author, or in that case all the combat advisors had suffered during those trying times. The book begins by the author describing his history. He begins by telling us of his family background. The memoir guides the reader through the life of the author in a very interesting yet morbid manner. Starting by his birth and his family’s background, his education, he moves on to tell us about his military training and then eventually guides the reader to his experience in Vietnam, which include not only his views over the war but also a number of interesting stories and encounters with the people and information about the land itself. Perhaps through this book the author wishes to share the grief and frustration suffered by him as a completely isolated man. This can be seen in a number of places where he constantly mentions his loneliness. In the words of the author, â€Å"I lived and fought with a South Vietnamese infantry unit. Much of the time, I was isolated from the other Americans and was usually the only American soldier with these Vietnamese soldiers. Most field advisors in 1963   Ã‚   had experiences similar to mine. The thousands of U.S. combat troops who came after me had different experiences and faced perhaps greater dangers. They have their own stories, unlike mine† (Dockery, Preface). But, the author also moves on to say that these experiences have had a profound effect on his personality. He believes that he was rather immature when he arrived in South Vietnam, but these experiences, the hardships he faced; even the loneliness helped him build his character and perhaps become a much stronger man. According to the author, â€Å"the cumulative effect of these events was to turn an immature and insecure person into someone capable, confident and caring. That is how I see myself today. We all grow up; the Vietnam War was the period during which I matured. Although my character was tested, I was fortunate and came home a stronger person† (Dockery, Preface). The book has been written by the author in a rather very interesting way, beginning as mentioned earlier from his childhood to his military services and then eventually to his return to USA and then back to Vietnam. The chapters have been given names which give us hints as to what to expect in the chapter. The names of the chapters are: Early Lessons, A volunteer, The participants, In the field, The cement plant, Delta Life, Back to the USA, Reflections, Return to Vietnam. The book has succeeded in presenting the abrupt and invalid of superfluities. The author portrays his aggravation with moral compass to eventually realize self actualization as persistent warrior turn civilian. This book is highly recommendable for anyone interested in policy planning, volunteerism and also for students of Asian American studies. The contents of the book are particularly persuasive for those obligated in the meandering rational, that basic disagreement founds a respected democratic value system. The reader here is given a loose end to think as to why unshakable dishonest civil war settings over and over again prompt this â€Å"Christo-American† reaction. After going through this book, it is hard to believe that anyone actually believed that experienced Vietnamese commanders, a vast number of whom had a very different schema, would take suggestions from a few newly appointed, rather inexperienced Americans. The author has criticized the ways of the Americans in a rather clear and concise manner without any care for anything. In very clear words, the author’s has presented a testimony which provides unavoidable confirmation that the outcomes of the Vietnam war were extremely clear since perhaps the start of 1962, when the troops had arrived there. The result of the war was evident but it went ignored by the higher authorities. The author has put forward the fact that perhaps the U.S. leaders would learn in a decade what the young officer’s at Vietnam learnt in perhaps a year only. The book and its realities are extremely important to go through and should especially be ready by the authorities that send soldiers off to war. The author in the book has openly claimed that for most part of his life, he was not a very caring person. He was never sensitive and could never understand the feelings of others, not even his mother, sisters or family. But after all that he saw in the Vietnam war, his heart started realizing and feeling these things. In the words of the author, â€Å"the letters I wrote to my parents from Vietnam were devoid of hardship, danger and combat. They touched on politics, weather, food, geography and religion. I was learning to be sensitive, incrementally. Still am† (Dockery, p.6). The book has a morbid outlook all the way through, for it is the tale of a man who has suffered a lot. It should be read by those who wish to join the military services for they have the right to know just what they might face during war. The realities and truths within these pages are to be read by all. Especially those who believe in the righteousness of the American military to know just how wrong their actions were. Every combat advisor at war has his own distinctive incidents and Martin Dockery provides us with something very readable and worth turning pages for. He explains that when they arrived at Saigon, both of the troops (the American and the South Vietnamese) were completely different from each other. They had difference cultures, religions, philosophies, educational backgrounds, traditions etc. What was worst was the difference between their languages which was the basic cause of an umber of misunderstandings and conflicts, which basically shows why he named the book ‘Lost in Translation’. As he was completely isolated, his qualities started being brought up in him. His service ended when he had ended up with malaria, hepatitis, dysentery, skin fungus and worms. The books takes us from his birth in White Plains, NY, to his education, the Vietnam experience as well as his service in the American army’s â€Å"Old Guard†. It is full of interesting stories from which we derive much morals and realize just how wrong the American military was during the Vietnam war. Conclusion In the light of the above discussion, we can hereby culminate that Lost In Translation Vietnam A Combat Advisor's Story, is a very well-known book which has been written by Martin J. Dockery. Martin J. Dockery was one of the vast numbers of combat advisors that were sent by President Kennedy to South Vietnam in order to teach them how to fight. The book is basically the author’s personal tale and he has written this in order to show just where the American military went wrong and faced disaster at Vietnam. He believes that most of the wrong doings were the attitudes of the Americans towards others, their arrogance etc. The book is a must read for all and it presents us with information about the sufferings of the combat advisors who had long before predicted that the American would face disaster but the higher authorities had ignored their warnings. Anyone who believes that the military is out to work for our best or that they would win the hearts of many must read this book to see what the military made these innocent people go   through. The outlook of the book is very morbid but that is because of the baseline of the book. It begins form his childhood and then guides the reader through his entire life including his education, military training, the Vietnam experience, then coming back to USA and then going back to Vietnam. The book is full of interesting stories and can be read by all especially the students of history. Works Cited Dockery, Martin. Lost In Translation: Vietnam: A Combat Advisor's Story.

Response paper - Essay Example In terms of genderization, feminist theories took a turn from studying female accessibility to technology, to examining the processes that developed technology as well as its female constitution. Presently, the feminist outlook on technology and the digital era is positive unlike its counterparts in 1980s reflecting a marked change in feminist theories of technology. De Lauretis seems to emphasize on the aspect of sexual difference throughout the paper as the concept was a prominent element of feminist writings during the 1960s and 1970s. Sexual difference is the idea that reinforces the differences between male and female, man and woman, as it creates a categorization that is an artifact, not of biology or sociology but of discursive constructs. De Lauretis has pointed several limitations of the term ‘sexual difference’ which includes its restriction on feminist critical thinking and recuperation of radical feminist thought to the bounds of one’s master’s wall (2). Then the author articulates the concept of gender as relating to technology as represented in various forms. McGraw’s paper on essentially â€Å"feminine† technologies explains rather novel concept of the term from a feminist perspective (13). Here, McGraw explains how certain female possessions such as bras, closets, collars, and bathrooms are â€Å"feminist† technologies because of their utility to women. While the word technology may engender necessarily male artifacts, McGraw explains how, a recognition of such things used predominantly by women will help us understand the technologies that were used previously. This will help us to expand our thinking of technology as not necessarily a piece of gadget that is electronic or digital but that which is of use to a particular section of the target users. In turn, this realization will help individuals to understand technology as not only comprising of male-oriented objects but merely anything that has been of
