Best Analysis Eyes of TJ Eckleburg in The Great Gatsby

Best Analysis Eyes of TJ Eckleburg in The Great Gatsby SAT / ACT Prep Online Guides and Tips In The Great Gatsby, in the middle of a strange, gray landscape, hovers a giant billboard of eyes without a face- the eyes of Doctor T.J. Eckleburg. It's a creepy image, and the fact that several characters seem disturbed by it means that it is very significant in the novel. But did you know that F. Scott Fitzgerald didn't make up this advertisement? If you image search "oculist shop sign," you'll see that this disembodied eyes thing was a pretty standard way to advertise places that sold glasses! So how does The Great Gatsby transform what would have a reasonable everyday image into a sign of the macabre? And why does this billboard affect the characters who see them so much? In this article, I'll talk about the places where the eyes of Dr. T.J. Eckleburg are mentioned in the novel, explain their symbolic meaning, connect them with the novel's themes and characters, and also give you some jumping-off points for writing essays. Quick Note on Our Citations Our citation format in this guide is (chapter.paragraph). We're using this system since there are many editions of Gatsby, so using page numbers would only work for students with our copy of the book. To find a quotation we cite via chapter and paragraph in your book, you can either eyeball it (Paragraph 1-50: beginning of chapter; 50-100: middle of chapter; 100-on: end of chapter) or use the search function if you're using an online or eReader version of the text. What Are the Eyes of Dr. T.J. Eckleburg in The Great Gatsby? Before delving into the deeper meaning of this image, let's get a general idea of what this object is. In the middle of Queens, along the road the characters take to get from West Egg to Manhattan, near George Wilson's garage, there is a billboard. The billboard is an ad for an optometrist (called an "oculist" in the 1920s). The image on the ad is a pair of giant disembodied blue eyes (each iris is about a yard in diameter), which are covered by yellow spectacles. The rest of the face isn't pictured, and the billboard is dirty with paint that has faded from being weathered. Key Quotes About the Dr. T.J. Eckleburg Eyes Before we can figure out what the eyes mean as a symbol, let's do some close reading of the moments where they pop up in The Great Gatsby. Chapter 2 The first time we come across Dr. T.J. Eckleburg and his eerie eyes, we are in the midst of a double whammy of terribleness. First, Nick has just described Queens as a depressing, crumbling "valley of ashes" that is "grotesque" and "desolate" (2.1). Second, Tom is about to introduce Nick to Myrtle Wilson, his married mistress. But above the grey land and the spasms of bleak dust which drift endlessly over it, you perceive, after a moment, the eyes of Doctor T. J. Eckleburg. The eyes of Doctor T. J. Eckleburg are blue and gigantic- their retinas are one yard high. They look out of no face but, instead, from a pair of enormous yellow spectacles which pass over a nonexistent nose. Evidently some wild wag of an oculist set them there to fatten his practice in the borough of Queens, and then sank down himself into eternal blindness or forgot them and moved away. But his eyes, dimmed a little by many paintless days under sun and rain, brood on over the solemn dumping ground†¦ I followed [Tom] over a low white-washed railroad fence and we walked back a hundred yards along the road under Doctor Eckleburg's persistent stare... "Terrible place, isn't it," said Tom, exchanging a frown with Doctor Eckleburg. (2.1-20) Just like the quasi-mysterious and unreal-sounding green light in Chapter 1, the eyes of Doctor Eckleburg are presented in a confusing and seemingly surreal way: Instead of simply saying that there is a giant billboard, Nick first spends several sentences describing seemingly living giant eyes that are hovering in mid-air. Unlike the very gray, drab, and monochrome surroundings, the eyes are blue and yellow. In a novel that is methodically color-coded, this brightness is a little surreal and connects the eyes to other blue and yellow objects. Moreover, the description has elements of horror. The "gigantic" eyes are disembodied, with "no face" and a "nonexistent nose." Adding to this creepy feel is the fact that even after we learn that the eyes are actually part of an advertisement, they are given agency and emotions. They don't simply exist in space, but "look out" and "persistently stare," the miserable landscape causes them to "brood," and they are even able to "exchange a frown" with Tom despite the fact that they have no mouth. It's clear from this personification of an inanimate object that these eyes stand for something else- a huge, displeased watcher. Chapter 7 The second time T.J. Eckleburg's eyes appear, Tom, Nick, and Jordan are stopping at Wilson's garage on their way to Manhattan to have it out with Daisy and Gatsby. We were all irritable now with the fading ale and, aware of it, we drove for a while in silence. Then as Doctor T. J. Eckleburg's faded eyes came into sight down the road, I remembered Gatsby's caution about gasoline†¦.That locality was always vaguely disquieting, even in the broad glare of afternoon, and now I turned my head as though I had been warned of something behind. Over the ashheaps the giant eyes of Doctor T. J. Eckleburg kept their vigil but I perceived, after a moment, that other eyes were regarding us with peculiar intensity from less than twenty feet away. In one of the windows over the garage the curtains had been moved aside a little and Myrtle Wilson was peering down at the car. (7.136-163) This time, the eyes are a warning to Nick that something is wrong. He thinks the problem is that the car is low on gas, but as we learn, the real problem at the garage is that George Wilson has found out that Myrtle is having an affair. Of course, Nick is quickly distracted from the billboard's "vigil" by the fact that Myrtle is staring at the car from the room where George has imprisoned her. She is holding her own "vigil" of sorts, staring out the window at what she thinks is the yellow car of Tom, her would-be savior, and also giving Jordan a death stare under the misguided impression that Jordan is Daisy. The word "vigil" is important here. It refers to staying awake for a religious purpose, or to keep watch over a stressful and significant time. Here, though, both of those meanings don't quite apply, and the word is used sarcastically. The billboard eyes can't interact with the characters, but they do point to- or stand in for- a potential higher authority whose "brooding" and "caution" could also be accompanied by judgment. Their useless vigil is echoed by Myrtle's mistaken one- she is vigilant enough to spot Tom driving, but she is wrong to put her trust in him. Later, this trust in Tom and the yellow car is what gets her killed. Chapter 8 Our last visit to the eyes happens during a private moment between the coffee shop owner Michaelis and George Wilson. Since Nick isn't actually there, this must be Nick's version of Michaelis's testimony to the police after the murder-suicide. "Have you got a church you go to sometimes, George? Maybe even if you haven't been there for a long time? Maybe I could call up the church and get a priest to come over and he could talk to you, see?" "Don't belong to any." ... Wilson's glazed eyes turned out to the ashheaps, where small grey clouds took on fantastic shape and scurried here and there in the faint dawn wind. "I spoke to her," he muttered, after a long silence. "I told her she might fool me but she couldn't fool God. I took her to the window" With an effort he got up and walked to the rear window and leaned with his face pressed against it, "and I said 'God knows what you've been doing, everything you've been doing. You may fool me but you can't fool God!' " Standing behind him Michaelis saw with a shock that he was looking at the eyes of Doctor T. J. Eckleburg which had just emerged pale and enormous from the dissolving night. "God sees everything," repeated Wilson. "That's an advertisement," Michaelis assured him. Something made him turn away from the window and look back into the room. But Wilson stood there a long time, his face close to the window pane, nodding into the twilight. (8.72-105) Here, finally, the true meaning of the odd billboard that everyone finds so disquieting is revealed. To the unhinged George Wilson, first totally distraught over Myrtle's affair and then driven past his breaking point by her death, the billboard's eyes are a watchful God. Wilson doesn't go to church, and thus doesn't have access to the moral instruction that will help him control his darker impulses. Still, it seems that Wilson wants God, or at least a God-like influence, in his life- based on him trying to convert the watching eyes of the billboard into a God that will make Myrtle feel bad about "everything [she's] been doing." In the way George stares "into the twilight" by himself, there is an echo of what we've often seen Gatsby doing- staring at the green light on Daisy's dock. Both men want something unreachable, and both imbue ordinary objects with overwhelming amounts of meaning. So in the same way Myrtle couldn't see the truth above, this lack of a larger moral compass here guides George (or at least leave him vulnerable) to committing the murder/suicide. Even when characters reach out for a guiding truth in their lives, not only are they denied one, but they are also led instead toward tragedy. The characters have no access to any of these. The Meaning and Significance of the Eyes of Dr. T.J. Eckleburg in The Great Gatsby In the world of The Great Gatsby, there is no moral center. Every character is shown to be selfish, delusional, or violent. Even Nick, who, as our narrator, is ostensibly meant to reflect on who is good and who is bad, turns out to be kind of a misogynist bigot. It's not surprising that none of these characters is shown to have faith of any kind. The closest any of them come to being led by an outside force, or voice of authority, is when Tom seems swayed by the super racist arguments of a book about how minorities are about to overwhelm whites. So it makes sense that Nick, whose job it is to watch everyone else and describe their actions, pays attention to something else that seems to also be watching- the billboard with the eyes of Doctor T.J. Eckleburg. The billboard watches the site of the novel's biggest moral failures. On a more local level, the garage is the place where Daisy kills Myrtle. But on a bigger scale, the "ash heaps" of Queens show what happens to those who cannot succeed in the ambitious, self-serving, predatory world of the Roaring 20's that Fitzgerald finds so objectionable. The problem, of course, is that this billboard, this completely inanimate object, cannot stand in for a civilizing and moral influence, however much the characters who notice it cower under its gaze. Tom frowns when he feels himself being watched, but this feeling does not alter his actions in any way. Wilson wants Myrtle to be shaken up by the idea of this watcher, a God-like presence that is unfoolable, but she is also undeterred. Even Wilson himself, who seems to feel the billboard is some kind of brake on his inner turmoil, is easily persuaded that it's just "an advertisement," and so nothing stands in the way of his violent acting out. Like Gatsby, who is also compared to "the advertisement of the man" (7.83), the billboard is a sham representation of a deeper idea. People want to read God or at least an overseeing presence into it, but, in the end, they are simply externalizing their anxiety about the moral vacuum at the center of their world. Not quite the kind of vacuum we're talking about here. Characters, Themes, Motifs, and Symbols Connected to the Eyes of Doctor T.J. Eckleburg Nick Carraway. Nick is the first to notice the billboard and describe it as a watchful presence. He finds it a discomfiting cap on the misery and desolation of the "ash heaps" that separate Long Island from Manhattan. In a way, the billboard does what Nick could never do- be a completely impartial, completely objective observer of the events around it. George Wilson. George seems to conflate the eyes of T.J. Eckleburg with his idea of an ever-present, all-seeing God. He reveals to Michaelis that part of his reaction to Myrtle's affair was to try to make her be afraid of a God who is watching her every move like the billboard does. In the end, after he seems completely unhinged by Myrtle's death, George stares at the billboard in the same way that Gatsby stares at the green light at the end of Daisy's dock. It's possible to conclude that when Michaelis tells George that the eyes are just an advertisement, he removes the last barrier preventing George from acting out his violent intention. Morality and Ethics. The values of the world within the novel seem to simply be: get whatever you want for yourself, as much as you can, in any way you can, and don't get caught. No one has an internal moral compass, and there is no external one either apparently. The eyes of TJ Eckleburg come closest to being an external motivator for characters to at least consider the morality of their actions, as they squirm and become uncomfortable under the eyes' gaze. Money and Materialism. The billboard is there in the first place as an advertisement, and thus also reflects the huge capitalist influence in everyone's lives. The real reason that there is no moral or ethical underpinning to the lives of these characters is that their world is based on a greedy, money-based notion of success. Even the object that is the closest thing to a religious figure is in reality trying to compel those who see it to buy something and make someone else richer. The Valley of Ashes. The billboard of the eyes of T.J. Eckleburg is located in the middle of what Nick calls "the valley of ashes"- the industrial section of Queens that connects the rich neighborhoods of the Eggs on Long Island and the similarly booming Manhattan. That the eyes watch over this neighborhood in particular is an indictment of the way those who can't claw their way to the top get left behind in the lawless Wild East, shaming those passing through who are taking advantage of the hard work of the poor. What makes the world of The Great Gatsby go around. Essay Ideas and Tips for Writing About the Eyes of Doctor T. J. Eckleburg Now that we've discussed the significance of the billboard advertising the oculist Doctor Eckleburg, let's figure out the best way to approach this symbol in an essay. Writing Tips Here are some tips for how to write an essay about the role of a symbol in a novel: Build from the text out. In this article, I first looked at the eyes in context and discussed the billboard's meaning in the exact places where it appears, and only afterward wrote about their general significance in the novel. Keep the same system in mind for your own essay: progress from small ideas to big ones to bolster your argument. Make an argument. It's not enough to just describe the symbol and explain its possible meanings. Instead, you have to make sure that you're making some kind of point about why/how the symbol works. How do you know if you're making an argument and not just saying the obvious? If you can imagine someone arguing the opposite of what you're saying, then you've got an argument on your hands. Don't overthink it. Sure, the billboard's giant eyes can be said to represent lots of things: God, moral failings, or the lack of ethical oversight on the East Coast. But that doesn't mean that it also stands for Gatsby's father, the freedom of sailing, or Daisy's childhood. In other words, watch out for stretching your symbol analysis too far from what the text is telling you. Essay Ideas Here are some possible essay arguments. You can build from them as-is, argue their opposite, or use them as jumping-off points for your own interpretation. What Wilson really wants when he's staring at the eyes of Doctor T.J. Eckleburg is the kind of intervention that a third-person narrator would normally provide: someone to punish the bad characters and reward the good ones. Because there's no supervising authority like that in the novel, Wilson takes justice into his own hands. The problem isn't that there aren't any moral rules in the world of the novel, but that everyone is so flawed that it would be impossible to figure out who is right and who is wrong. That's why the only appropriate God figure is an inanimate object. The eyes are placed on the road between Manhattan and West Egg rather than in one of those places because this road is a place where characters could make different choices, and where they can make the decisions that affect their lives in either one of those destinations. Who has the most options in the novel? Who has the least? The Bottom Line The Eyes of Doctor T.J. Eckleburg is a billboard advertising an oculist that features a pair of giant disembodied blue eyes covered by yellow spectacles. The eyes pop up in: The beginning of Chapter 2, when Nick's personification of the inanimate eyes implies that they represent a huge, displeased watcher or the characters' moral failures. In the middle of Chapter 7, when the eyes are a warning to Nick, who perceives them as an image of a higher authority sitting in judgment. In the middle of Chapter 8, when Michaelis's explanation that the billboard isn't actually God releases the violence Wilson has been holding in check. The oculist's billboard and its creepy eyes watch over a world without a moral center, where every character is shown to be selfish, delusional, or violent, and it is positioned on the site of the novel's biggest moral failures. This billboard, a completely inanimate object, cannot stand in for a civilizing and moral influence, however much the characters want to read God or at least an overseeing presence into it. The Eyes of Doctor Eckleburg are associated with: Nick Carraway, who notices it because the billboard does what Nick could never do- be a completely impartial, completely objective observer of the events around it. George Wilson, who conflates the eyes of T.J. Eckleburg with his idea of an ever-present, all-seeing God. Morality and ethics, which don't exist in a world where the rules are: get whatever you want for yourself, as much as you can, in any way you can, and don't get caught. The Valley of Ashes, an industrial neighborhood that is an indictment of the way those who can't claw their way to the top get left behind in the lawless Wild East. Money and materialism, since the billboard reflects the huge capitalist influence in everyone's lives. What's Next? Refresh your memory of the chapters where this symbol appears: Chapter 2, Chapter 7, and Chapter 8. Compare and contrast Tom and George to see why they react to the billboard's unsettling eyes in such different ways. Consider the location of the billboard by reading about the valley of ashes and the other settings in the novel. Check out all the other symbols that enrich The Great Gatsby.

Dance and Identity Essay Example | Topics and Well Written Essays - 2500 words

Dance and Identity - Essay Example This essay focuses on discussing dance as a form of performing art where your body posture plays a really crucial role because this performing art needs to have amazing elegance and grace in your body. The performer expresses him or her through the medium of his own body. According to the theory of performativity, gender should not be considered as a noun that acts but it is always a doing. This statement is very true in the context of dance or any other performing art where the actor is a performer in spite of his gender identity. The researcher uses Kathak dance to provide an example for better understanding of the issue. Kathak is one of the oldest classical dance forms which originated in North India. Dance is performed by both male and female. The masculine dance is always vigorous and aggressive while the feminine dance form is very delicate and more graceful. Basically in Kathak, the artist has to have the knowledge of both of these patterns. To conclude, the researcher states that sex has been an obligatory injunction for the body to become a cultural sign. Since ancient time dance has many stereotypical approaches in all around the world. Basically dance is an elegant art which needs to be enjoyed by an artistic vision. Objective should be taken into consideration while assessing the dance performance and not the gender identity of the artist. Gender issue should not be included and this art should not be kept constrained in the certain framework of gender identity.

Can the fund by IMF save the world economy Essay

Can the fund by IMF save the world economy - Essay Example The functions of the IMF are quite broad and it ranges from enhancing monetary cooperation between nations to maintaining an acceptable level of balance of payment. Other functions include promoting stability of exchange rate, ensuring smooth flow of capital and providing funds to nations. Providing financial assistance is one of the major functions of the IMF so that problems relating to balance of payment can be reduced (Weiss, â€Å"International Monetary Fund: Background and Issues for Congress†). Monitoring the fiscal and monetary functions of nations under its membership and technical advice are also functions of the IMF. The purpose of this paper is to highlight the role of IMF in helping to protect the world economy. The paper is divided into five main sections. The chapter of literature review focuses on the key economic theories in explaining the role of the IMF. The methodology chapter briefly discusses the methods of conducting this essay and the section on results provides empirical verification of the ways in which the countries has performed with the help of the funds provided by the IMF. Historically, the mechanism of working of IMF is rooted in the Keynesian macroeconomics. The IMF is essentially a monetary organization that focused on the monetary help to adjust balance of payment of a country. The works of Friedman (1950 cited in Davidson 64) regarding floating exchange rates and monetarism had influenced the functioning of the IMF. Keynes was one of the founding fathers of the IMF and he had applied his countercyclical monetary and fiscal policies to combat unemployment and recessions. However, over the years the functioning of the IMF had changed dramatically with the evolution of the new classical macroeconomic ideas. The proponents of the Keynesian and the post Keynesian theories had suggested that uncontrolled flow of capital makes countries highly vulnerable to events like banking crisis and

The Value of Evaluating University Students Essay Example for Free

The Value of Evaluating University Students Essay Education can be referred to as the development of character together with the persons mental powers . It encompasses teaching as well as learning of specific skills . It imparts knowledge on a person who is getting educated. Education plays a very critical role in the development and growth of each and every person . It is considered to equip a person with the knowledge that is required in day-to-day activities that one may undertake. The potentials of a person are put into maximum use through the process of education. This is because education empowers a person to use his or her skills, or talents to maximum use. Education enables a human being to be in his proper sense. Education is very important in a person’s life. The values that education gives to a person are incomparable with those of an uneducated person. Education is considered important for several reasons. One is that, it trains a person `s mind. An individual can be able to learn and practice it. It also makes a person to become a right thinker. This means, that one can be able to think wisely and appropriately . It enables one to think and make decisions as required. Education is very crucial that in enabling people to receive information from the external world . One can be able to learn about different states or regions in the world and the occurrences in those particular places. Past history information can be acquired through education. Present necessary information as well. Education has different levels depending on the content of education at that level. Age also determines which level of education one should be in. Globally university education is the highest institution of learning. It offers knowledge and skills that are very specific to certain profession. For example students are trained depending on the profession that they want to be in after completing their education. In most universities, students are evaluated through examinations. In this essay, the subject of whether university students should be evaluated will be discussed. Evaluation assists tutors or lecturers to find out what knowledge, skills, attitudes or behaviour the course has instilled to the students (William, 2006). Through examinations as a way of evaluation, students are able to give to the lecturer what they understood or learnt from a certain course. Evaluation assists lecturers to set clear, measurable and realistic objectives of the course to be taught . The lecturer can be able to find out how much students can learn over a given period of time. For example, a course with a lot of content if covered over a very short period of time, students may fail to understand it better showed by poor performance in their examinations. Through evaluating students, a lecturer can develop and select the course content that can achieve the goals of that particular course. The students understanding of the course indicated by evaluating him or her shows this. This helps in ensuring the quality education given to the students in maintained at all times, or even improved. Evaluation encourages seriousness of the student to education. The methods of evaluation used demand that students must read thoroughly, as well as understand the content of the course. This means that the knowledge can be absorbed in the students mind. They can also apply the skills in their practical work correctly. Teamwork spirit is promoted amongst the students. This is whereby assignments that are down in teams encourage sharing of knowledge and ideas. They can work together to ensure they achieve their main objective, which is their success in that course. Evaluation encourages solving of problems in a course if they arise . For example failure of students to understand a particular course may be as a result of other factors . For example, poor lecturing or poor concentration of students in class. The problem can be addressed to ensure success. Evaluation promotes hard work in students Assignments or an exam obligates a student to research, learn and even understand much better. Evaluation has its negative face also . It may promote vices in the education system. The necessity of the student to pass evaluation tests may cause them to cheat during the examinations. This is whereby students may carry reference materials, where they can refer to for the correct and accurate answers. This lowers the value of education that the student gets. Selective reading and understanding of the course by the students may be encouraged by exposure to the evaluation tests. The students concentrate on reading and understanding, only what might be examined . The student cannot therefore acquire, all the required skills and knowledge that the course should give him or her. Evaluation may not always show the true ability of a student. For example, a student may be given a low grade simply because he or she never excelled in a certain test. Unfortunately, it might be that the student was only evaluated on few topics that he or she did not understand . If one would be examined all topics of the course, they would get a good grade. Students evaluation at the universities should be done but care should be taken to ensure there is high quality of education maintained. References William M. 2006. Research Methods Knowledge Base.

Dbq: French and Indian War

DBQ the French and Indian War The French and Indian War is known as an unintentional war sparked by a young George Washington’s actions towards the French ambassador. Both the English and French wanted to obtain control of the Ohio Valley. Each group desired to show their superiority and gain the benefits of the new world. The English and French could not solve their disagreement peacefully, and war was inevitable. The war not only changed the new world forever, but also, Britains relationship between its American colonies.The relationship between Britain and its American colonies was transformed through the political, economic, and ideological relations, due to the French and Indian War. Britain’s political relations with its American colonies were effected as a result of the French and Indian War. America today, as we know it, would not be the same if the English had not been victorious over the French. The war determined who would gain control of the new world. The m aps in Document A show that before the war, the French controlled most of the new land, but after the war, the English had secured the new world as its territory.It is easy to see that Britains victory over the French helped Britain politically, however; it produced tension with its American colonies. Shortly after the war, England realized what the war had really cost them tons of money they did not have. Britain expected the colonies to help pay the debt from the war, but the colonists felt it was not their responsibility. This controversy contributed to the political strain between Britain and its American colonies.The French and Indian War altered Britains relationship with its American colonies drastically, as Britain imposed its political authority on the colonists. Britains relationship with its American colonies was not only altered politically due to the French and Indian War, but also through its economy. The British began placing taxes upon the colonists and essentially t elling them what they could and could not do and who they could and could not trade with. The colonists were infuriated and felt that the taxation was unjust. Document F states the reason that taxes were placed upon the colonists. TheBritish Order in Council clearly states that, â€Å"we find that the revenue arising there from is very small and inconsiderable,†¦and is not yet sufficient to defray a fourth part of the expense necessary for collecting it. † The commissioners said that all the money it took to make the war happen was not paid back through the land acquired; so, as a result, taxes were placed upon the colonists. Another document that supported this claim about financial troubles was Document H. The picture in Document H was meant to show that after the war, Britain faced extremely rough times economically. Some colonists were depressed, sorrowful, and penniless.The outcome of the French and Indian War damaged Britains economic relations with its American co lonies. The American colonies ideological relations with Britain changed after the French and Indian War. All colonists did not view Britain the same way. In documents D and E, two very distinct views of Britain were displayed. The solider in Document D writes. â€Å"Therefore we now see what it is to be under martial law and to be with [British] regulars, who are but little better than slaves to their officers. † The Massachusetts soldier in this document hated Britain and felt they were treated no better than the slaves.Although, Document E stated, â€Å"Here shall our indulgent Mother, who has protected us, be served and honored by growing Numbers, with the Duty, Love and Gratitude, till Time shall be no more. † Reverend Thomas Barnard said in his sermon that Britain protected them. He felt the colonists should love, honor, and serve Britain forever to show their appreciation. Reverend Barnard viewed Britain as a blessing from God and he loved Britain. The colonists ’ views of Britain were not all the same, while some loved and appreciated Britain, but others hated and criticized them.The French and Indian War completely changed the ideological relations between Britain and its American colonies. As can be seen, Britains relationship with its American colonies was undoubtedly altered due to the results of the French and Indian War. Britains victory over the French came at a cost, as Britain’s grasp on its American colonies began to slip away, and the results of the war changed America as it is known today. The relationship between Britain and its American colonies was altered through the political, economic, and ideological relations, as a result, of the French and Indian War.

Evaluate the Information Processing Models to Learning, Distingush the Main Features of the Multi-Store Model Essay

The main thrust of this assertion is to give an evaluation of the information processing models to learning and paying particular attention to features of the multi-store model. According to Ashcraft (1994) information processing model is a framework used by cognitive psychologists to explain and describe mental processes. The multi-stores model propounded by Atkinson and Shiffrin(1968) is a classic model of memory, which describes memory in terms of information flowing through a system. However the model is not without flaws, as it possesses weaknesses as show be critically analyzed in this evaluation. The information processing model concentrates on how information from the environment through the senses is processed and utilized by the brain.Schunk(1996) posits that the information processing models are various theoretical perspectives dealing with the sequence and execution of cognitive events, mainly focusing on how people react to environmentalstimuli, encode, store, and retrieve when needed. Thus giving the perspective that learners are active seekers and processers of information. The flow of information primarily can be traced from the environmental stimuli. These are raw facts and figures that we capture from the surrounding using our senses. A stimulus can move from our senses to the short register, when we pay attention to the stimulus, and thus our internal process begins. According to Baron (2001)learning becomes the process of commuting our symbolic representations to memory where there may be processed and the study of learning is primarily through the study of memor y The multi-store model is a classical model of memory which was suggest that memory is made up of a series or stores and information is processed and stored in three stages namely sensory, short term and long term memory. Atkinson and Shiffrin (1968) describes memory in terms of flowing through a system. Information enters the sensory memory through detection environmental stimuli by the sense organs, then through the process of ‘attention’ and ‘perception’ moves to the short-term memory. Through rehearsal the information may be transferred to long term memory, and if not rehearsed it is then lost from short-term through the process of displacement or decayMcLeod,2007) Sensory memory is a brief store of information from the environment,maintaining a duration of a quarter to half of a second(Fieldman,2010) The sensory register picks up all the environmentalstimuli reaching our senses.The capacity of th sensory memory is quite large,although it only lasts for milliseconds, as it holdsinformation associated with the senses.If our working memory is relatively free of work,we might pay attention to the new input and if not, then we would not notice or we quickly forget the new information(Baddeley and Hitch,(1974). The other main feature of this model is the short-term memory,which is a temporary store for a limited amount of information and stores from a duration of 0 to 18 seconds,(Fieldman,2010). In this storage information is encoded mainly as echoic. Baron, (2001) postulates that short-term memory can handle about 7 objects at once, but this can be improved by chunking, which is the grouping of items into chunks and this information can be maintained by rehearsal or association of the information you are trying to remember with already existing knowledge.Therefore the short-term memory becomes vital as this is where consciousness exists and thinking is done. Long term memory is the third main feature of the model,which represents our permanent storehouse of information,and its capacity is unlimited(Ashcraft,1994). There are three categories of long term memory, semantic(for verbal information and meaning), episodic memory(for events) and procedural memory for how to do things. The prospect of information reaching the long term memory according to Driscoll(1994) depends upon the length of the message and familiarity of it with information already stored. The major strength of this model is based on its ability to set a foundation on other studies as memory studies provide evidence to support the distinction between short term and long time. Mcleod (2007) posits that the model is influential as it has generated a lot of research into memory. Furthermore, studies of amnesiacs also supported the essential of this model. This show the relevancy of the information processing model to learning as it is consistant with empirical findings and provides an excellent framework for understanding the principles of effective learning. The information processing model is also blamed for over simplifying facts and does not account for the type of information processed. The working memory is treated as a simple store of memory. This view is contradicted by Baddeley’s(2001) model of working memory which consists of three components, theexecutory loop, and visual spacial sketchpad,with uses which vary from selecting incoming information, determine processing and constructing meaning through inferences and subsequently transfer the processed information to long term or delete it from the memory system altogether.Therefore,despite that, the information processing model provides a conceptual model which explains the different functions and constrains on human memory it fails to recognize that the short term memory and long term are more complex than previously assumed. The interactions between short-term memory and long term memory were under emphasized and do not distinguish between levels in the long term memory,and of essence does not explain how the long term influences short term and sensory memory. Mcleod (2007) viewed the model as a one way or linear with rigid ways of operation, and also argues that rehearsal is too simple to account for the transfer of information. Schraw (2001) articulated that several useful terms have been developed to elaboratecognitive processing especially in working memory, for example the limited cognitive resources and attention resources, which help explain why there are differences between one learner and another.Therefore these and the fact that it is just a model and there is not really a way to prove its true, contributes to the view point that the information processing model has significant. In conclusion, the information processing model gives the three vital stages of information processing, which are greatly regarded in most recent studies as they have provided a framework for understanding principles of effective learning. Therefore despite the great number of flaws the model is quite significant. REFERENCE 1. Ashcraft,M.H (1996), Human Memory and Cognition, Harpercollins College :DIV 2. Atkinson, R.

American Revolutionary War - Ticonderoga and Crown Point essays

American Revolutionary War - Ticonderoga and Crown Point essays American Revolutionary War - Ticonderoga and Crown Point The immediate object of the attack on the British Forts at Ticonderoga and Crown Point on May 10 and 11, 1775 was first to capture the forts themselves, but also to obtain a cannon and supplies to use for the impending seige of Boston. Washington, who assumed command of the American forces on July 2, 1775, could not attempt this attack without heavy artillery, which was procured by Colonel Ethan Allen, Colonel Benedict Arnold and Colonel Seth Warner with Vermonts Green Mountain Boys. Green Mountain Boys, was the name of a group of soldiers from Vermont led by Allen, Warner and Arnold. They took their name from the Green Mountains in Vermont. The Green Mountain Boys were originally organized by Ethan Allen before the revolution to protest the claims of the New York government to Vermont territory, and were later joined by Seth Warner and Benedict Arnold. Seth Warner, was born in Connecticut and later moved to Vermont, where he was declared an outlaw in 1771 for forcibly resist! ing a New York claim to the area, and had a reward offered for his capture. Under Ethan Allen and Benedict Arnold, he participated in the seizure of Fort Ticonderoga and led the force that took Crown Point the next day. Later that year, he was elected lieutenant-colonel commandant of the Green Mountain Boys. Ethan Allen was also born Connecticut, moving to Vermont in 1769. He became involved in the struggle between New York and New Hampshire for control of the region, just like Allen was. The New York authorities rejected an appeal that the region be established as a separate province, and Allen organized a volunteer militia, called the Green Mountain Boys, to resist the New York cause. Volunteers were raised by the Committee of Correspondence. They recruited fifty men and three hundred pounds to set up the Green Mountain Boys. Allen too, was declared an outlaw by the governor of New York. At the...

Promote Your Content Marketing

Promote Your Content Marketing We all want more visitors, more audience, and more traffic to our blog, but how will they all  find us? These days everyone is creating content, which is only compounding the problem. Isnt it impossible to  stand out from the masses and become a high-traffic blog? Its not impossible–your blog can stand out–but you need to become a public relations (PR) wizard in order to do it. One of the big secrets to understanding how blogs grow is to know the difference between PR and promotion. Without understanding the difference between the two,  the result is wasted  efforts to promote and grow your blog that feel random and without a solid strategy.  For example,  while it may make sense to write a guest post, does it really make sense to write a guest post for that particular blog? And, if I write a guest post for that blog, what topic should I write about for the best  advantage? This is where a clarity between promotion PR comes in handy. Let’s take a look. A successful blog is one that knows the difference between PR and Promotion.The Difference Between Blog Promotion And PR Promotion is what we usually think about when we talk about building traffic for our blog. Promotion is: Getting people to read your content by stimulating demand for your content across a variety of channels. On the flip side, PR is: Getting people to respect what you  have to say, and ensuring that  the overall company has a  strong public image and an abundance of  good will. In some ways, blog promotion is about the short(er) term click-throughs and links, where as blog PR is about building a long-lasting reputation as the go-to blog for expert information. For example: The Moz Blog  as the go-to SEO blog Social Media Examiner as the go-to blog for social media Copyblogger  as the  go-to blog for  copywriting Inbound Hub  as the go-to blog for inbound marketing So, how do these blogs do it? Easy! All it takes is a relentless focus on both blog promotion and blog PR. Let’s take a look at how they are different. Blog promotion is something that we talk about often here at . We advocate several strategies like email marketing, a social media promotion schedule, and repurposing your content, but there is even more to think about. I tend to look at it as four  different layers of blog promotion. 1. Owned Channels The first layer is made of up of your own channels. These might be a huge  email marketing list, a great social media presence, and  a  thorough  social media promotion schedule. These are your own channels, and they are only  the tip of the iceberg for promoting your content. 2. Earned  Channels The earned channel is made up of the various social sharing done  by your audience. This includes social media shares, nomination style distribution outlets like Inbound.org or Buffer Daily, and link-backs from other bloggers. This is primarily driven by high quality content that is easy to share. 3. Paid  Channels While  often ignored, paid promotion channels can bring a good boost to any blog, and are a good means of promotion. Great examples of this include Facebook, Twitter, StumbleUpon and Reddit. 4. Syndication  Channels Reposting (or repurposing) your content on other sites is also a great promotion strategy. Examples of this include allowing your content to be reposted on another blog, or recreating content in a new form such as SlideShare are podcast topic. Blog PR is an entirely different process than promotion with a very different goal. Blog PR tends to focus on the long term strategy. I like to think of it like this: blog promotion aims for clicks, shares, and traffic, while PR   aims for expertise, trust, and good will. It may sound hard put into action, but it really isn’t. The layers of PR   can be broken down into different audience groups like the following: 1. Subscribing Audience The first layer in your PR   strategy is definitely your current audience. This should be easy, since they are already â€Å"true believers.† You will primarily reach this group with your owned channels, and you job is basically to just not screw things up. 2. Emergent Audience The second layer of PR   is made up of the â€Å"sometimes audience members that are familiar with you, but haven’t become a â€Å"true believer† yet. These members may have visited your site once or twice, but are not yet a subscriber. These are a  common audience type for content marketing, as explained here by Rand Fishkin. 3.  Influencers The influencers layer is made up of the  connectors that already know and are connected with the people you should be talking to. You need to  cross-pollinate with these groups. Influencers help you bridge the gap between yourself and new audiences. This can be accomplished through strategic partnerships, and even the â€Å"expert† posts that bring influencers together. 4. Permitter Audience I am going to dig into this strategy a bit more later on, but the permitter audience is composed of various audience segments that you ultimately want to reach. A lot of people talk about how to understand your audience  in blogging, but they don’t always discuss how to reach these people in a practical way. This is where a strong guest blogging strategy comes into play. How  Audience Building Really Works Looking at the layers of PR   above, it is pretty easy to see how a blog audience growth works. The big idea here is to turn permitter audience members into subscribing audience members by working them through the PR process. A great way to do this is with a strategic guest blogging strategyby guest blogging. Here’s how. First, group your audience into a set of audience segments. If you need to better understand your audience, there are many ways that you can learn about them using things like Google analytics and other methods. As example of this can been seen in a few audience segments that we have here at . These audience segments could be considered your ‘permitter audience. Once you have your audience segments identified, you need to find blogs that are already serving these groups. These are the influencers that I mentioned above. They will be able to connect you with the people that you really want to talk to. From there, begin reaching out the appropriate blogs, and provide them with awesome content that will both benefit their audience and help grow yours. It should begin to look like a wheel. Each guest post will connect you to these audiences, and help define your PR strategy. Since you are not being paid to blog, you will be building good will and recognition with the very audience that you are hoping to serve as subscribers. While this isn’t a ‘get tons-of-emails quick’ strategy, it is definitely a great way to grow your influence and your long term growth. As your permitter audience is exposed to you over and over again, you will build the trust and pull necessary for them to look into what you have to offer.

Syrian Government Research Paper Example | Topics and Well Written Essays - 1250 words

Syrian Government - Research Paper Example It states that Syria is an integral part of the Arab homeland and that all the people of the country have all the legislative power. The president and the members of parliament are elected by the people through their votes. However it appears that the enforcement of these principles is not ensured by the government since many years. Branches of the Government The structure of the Syrian government consists of the executive, the legislative, and the judicial branches. The Executive Branch The president is the head of the state and the chief officer of the government. He is elected by the people through referendum for a term of seven years. The constitution required that the president be of no less than 34 years of age and a Muslim. The constitution gives right to the president to appoint two vice-presidents, to name the prime minister and to dismiss him, other deputy minister, the members of the Cabinet and the military officers. Dr. Bashar al-Assad is currently serving as the preside nt (Britannica). The Legislative Branch The legislative branch is called Majlis-al-Shaab or the People’s Assembly. It is a 250-member unicameral body. The members are elected by the people through elections for a term of four years. People’s Assembly is represented by the members of different political parties. However, the majority of the seats are reserved or the National Progressive Front (NPF) which consist of the members of the Baath Party (Cafe Syria). The Council nominates a candidate for the presidential elections, discussion of economic matters and approval of the budget and the government policies. It also enacts the laws; however, initiation of law is not covered under its functions. The Judicial Branch The judicial system of Syria consists of courts at three levels: Courts of first instance (which comprises of magistrate and peace courts), courts of appeal (there is one court of appeal per province like a High Court), and the Constitutional courts which is the highest tribunal authority. The judicial system itself has the elements of Islamic, ottoman and the French Laws. The Supreme Constitutional Court is the head of the judicial system. It’s members consist of a chief justice and a bench of four different judges who all are appointed by the president for a period of four years (Mongabay). Problems with the Syrian Political System Although the constitution of Syria says that its people have every right to elect and appoint the president in general elections, the president is actually imposed through the unopposed popular referenda. The passing of presidential title by virtue of hereditary entitlement is quite apparent although the constitution says the government is of the republic form. And many attempts are made by the government to remove the opposing forces and continue to pass the title in this way. For example, in order to make Bashar (Hafiz al-Assad’s son), eligible for nomination in the presidential election, th e minimum age restriction was changed from 40 to 34 in 2000. Moreover the people cannot change the government. Most of the power resides with the president and he has the power to dissolve the legislature as well. The People’s Assembly may criticize the government’s policy or express its views on the economic matters, but it cannot initiate the law. The degree of public accountability is minimum and the government does not tolerate any political opposition (Mongabay). Syrian and U.S Political Systems Compared In this section
