A & P Summary

...John Updike's short story "A&P" is about a teenager who has to make a serious decision. The story is set in an A&P supermarket in a town north of Boston, probably about the year 1960. As the plot unfolds, Sammy changes from being a thoughtless and sexist boy to being a young man who can make a decision, even though it might hurt him. Sammy tells us he is nineteen years old. He is a check-out clerk in the local A&P, where the boss, Lengel, is a friend of Sammy's parents. Sammy does not seem to like his job very much. He calls one of his customers a "witch" and says the other customers are "houseslaves" and "sheep." He himself comes from a middle-class family. When they have a party, he says, they serve "lemonade and if it's a real racy affair Schlitz in tall glasses with 'They'll Do It Every Time' cartoons stencilled on" (15). In addition, Sammy is sexist. He gives long, loving descriptions of the girls who cause all the trouble, and he thinks at first that girls may not even have minds, asking, "do you really think it's a mind in there or just a little buzz like a bee in a glass jar?" (13) However, he does change as the plot goes on. The plot of the story deals with three girls who come into the store dressed only in bathing suits. They make their entrance in the very first sentence, and they complicate Sammy's life. At first, Sammy, his older friend Stokesie, and McMahon the butcher all look at the girls lustfully. But of them all, only Sammy......

A&P and Araby

...A&P and Araby John Updike's A & P and James Joyce's Araby share many of the same literary traits. The primary focus of the two stories revolves around a young man who is compelled to decipher the different between cruel reality and the fantasies of romance that play in his head. That the man does, indeed, discover the difference is what sets him off into emotional collapse. One of the main similarities between the two stories is the fact that the main character, who is also the protagonist, has built up incredible,yet unrealistic, expectations of women, having focused upon one in particular towards which he places all his unrequited affection. The expectation these men hold when finally "face to face with their object of worship" (Wells, 1993, p. 127) is what sends the final and crushing blow of reality: The rejection they suffer is far too great for them to bear. Updike is famous for taking other author's works and twisting them so that they reflect a more contemporary flavor. While the story remains the same, the climate is singular only to Updike. This is the reason why there are similarities as well as deviations from Joyce's original piece. Plot, theme and detail are three of the most resembling aspects of the two stories over all other literary components; characteristic of both writers' works, each rendition offers its own unique perspective upon the young man's romantic infatuation. Not only are descriptive phrases shared by both stories, but parallels occur with...

A&P Lab Report

...The Effect of Aerobic Exercise on the Cardiovascular and Respiratory System Anatomy & Physiology of Sport and Exercise Task 2: Laboratory Report BTEC Extended Diploma in Sports and Exercise Science Year 1 Contents Page 1 Front Page 2 Contents Page 3 –8 Introduction 9 Method 10-11 Results 12-18 Discussion Introduction The hypothesis for this project is to look at the effects of exercise on the cardiovascular system (heart rate and blood pressure) and the respiratory system (breathing rate) which will increase with exercise. This is because as we begin to exercise our bodies demand for oxygen rises as the need for energy increases, therefore we must breathe at a faster rate in order to supply oxygenated blood to the working muscles. The heart must beat quicker in order to push the oxygenated blood to the working muscles and this in turn will increase blood pressure. The Cardiovascular System. The cardiovascular system does not consist of the lungs. Cardio = the heart Vascular = the blood and blood vessels The function of the cardiovascular system is to deliver oxygen and nutrients to every cell in the body and carry hormones to different parts of the body. Remove waste products from energy production, maintain body temperature and homeostasis. The function of the blood vessels in particular is to deliver oxygen rich blood around the body and remove waste......

A&P Case Study

...A&P II Lab Writing Assignment Writing assignment In the study provided, the information shows a larger difference in heart attacks for males over females under the age of 55. One reason for this difference is the amount of physical activities such as sports and other training. Males at that younger age are putting more force on their heart more often. Women on the other hand do not have the rise in testosterone during these physical activities and typically don’t do as much. After the age of 55 the study shows a general equaling out of the heart attack rates. This could possibly be due to the fact that women are going into menopause, while men are still at risk they don’t have the increased testosterone drive to push their abilities like when they were younger. Women over 55 began all the necessary changes in their body including hormone shifts and chemical imbalances. This could be a reason for why their heart attack rate becomes more even with men. Based on these results and my hypothesis, I believe more work should be put into studying the results of hormonal and chemical changes, in both males and females, on the heart. The possibility that a pill or alternative form of medicine might be able to level out these imbalances and provide a longer life span is very important. Supplementation of things like fish oils has been said to help with heart health but more research should be done in order to expand the knowledge on this subject. Currently there is...

Updike a&P

...Updike’s A&P Sample Writing – Alternate Ending Page 8, Last Paragraph I look around for my girls, and to my surprise, they were waiting for me outside the A&P. As Queenie started to walk up to me I noticed some young married screaming with her children about some candy they didn't get by the door of a powder-blue Falcon station wagon. I couldn’t believe that Queenie and her lackey’s were actually going to speak to me. “Thanks for standing up for us but you didn’t have to quit your job.” “It’s no big deal, it’s not like I was trying to make a career out working at the A&P.” “Well since you are no longer working, would you like to join us and go for a swim?” “Sure, I have no plans since I was scheduled to work till 7.” As we started to walk towards the girl’s car, I couldn’t help but look back in the big windows, over the bags of peat moss and aluminum lawn furniture stacked on the pavement, I could see Lengel in my place in the slot, checking the sheep through. I thought to myself there has to be more to life than that. I could not imagine my life ending up the way Lengel’s life was, always slaving away at the A&P and becoming so narrow minded as to refuse business because of the way someone was dressed. Why be so rude about it? Obviously he was just a miserable human being and misery loves company. This was going to be a new start for me. Something great was coming my way but I was unsure of what it could be but I can’t wait to embrace life and all it...

A&P Contrast

...“A&P” and “Gryphon” have two very unique story plots yet they seem to resemble one interesting characteristic that develops throughout the story leading to an interesting turn of events. The stories are both told in first person narrative and have a sort of interesting rebellious appeal to them. It begins with the contrast between the stories plot development but leads to a troublesome “fork in the road” type scenario that puts an interesting twist onto the conclusion of the story. Some may see rebelliousness as acting against the norm but “John Updike” the author of A&P tells a tale of how two different sets of people both defy society and begin paving a way of change into the new generation. “Gryphon’s” story set is told from how a change in the way we think may leave us changing the way we live our lives. The stories may seem to have different alternatives overall but the way they are portrayed by the authors have a similar comparative aspect that can be looked at from both angles regardless of the storyline. When someone seems destined to choose a different path in life often times people may see this person as an outcast or indifferent to some. In A&P Sammy seems to not to be fulfilled with the way he spends his dull uneventful youth life ultimately leading to the defiance and betrayed to his boss over a deemed inappropriate act. “"Is it done?" he asks, the responsible married man finding his voice. I forgot to say he thinks he's going to be manager some......

...the blood faster. The increase in stroke volume is from the heart pumping more blood to the necessary parts of the body. 6. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving supporting data from your experiment that supports your corrections. I predicted that both HR and CO would increase with exercise. I was correct as with the increase of physical activity, the requirement for oxygen becomes an increased demand which relies on the heart to work harder to provide both oxygen and nutrients to the cells throughout the body. I predicted the SV would decrease, which was incorrect. After selecting that option and beginning the lab, I realized this was a mistake. This is because the amount of blood remaining would have to increase, thus making the SV Application 1. We measured the stroke volume of the left ventricle. What was the average stroke volume of the right ventricle at rest and after exercise? The average stroke volume for the right ventricle at rest and after exercise would be the same. 2. Assume that for one beat, the stroke volume of the left ventricle is greater than that of the right ventricle. Explain why in a normal heart this would be corrected on the next beat. It would be corrected because there would be an icrease of pulmonary pressure in the veins and could cause the left atrium to fill up faster which could then lead to death by drowning in......

P 460

...Revision question p 460 1. Casual attribution is a method in which to attribute what caused success or failure in a certain situation. There are four categories which are Ability, Luck, task difficulty and effort. These four categories can be split into 2 sub-groups Internal/ external and stable/unstable. 2. Attribution theory looks at the reason for why someone failure or succeeded in a certain situation. This is important from a sports psychologists view because models such a Wieners give people the ability to blame their failure on external reasons out of there control and therefore keep motivation high. 3. The locus of causality dimension indicates whether the attribution relates to factors that are either internal or external to the performer. Effort and ability represent internal factors while task difficulty and luck are external and are known as environmental variables. Stability indicates whether attributions are stable or unstable. Stability refers to the degree of permanence associated with an attribution factor. A stable factor is considered permanent and unchangeable, for example ability. An unstable factor, by contrast, is temporary and can be changed. Luck is an example of an unstable factor. Control, which will be considered later, is a third dimension of the attribution model. It is not referred to directly in the specification but is a key factor in the important process of attribution retraining. 4. If a hockey player continues to lose......

A&P Analisys

... John Updike’s “A&P” as a provocative tale of social perception In order to understand the two stories on John Updike’s “A&P”, the characters have to hold the weight of being the most important theme in the short story. The first set of characters consists of Sammy, the Girls, and Lengel who all dictate the first short story from Sammy’s point of view. The second of the two tales Updike pens about in this short, is that of where he makes us question what being “decent” by society’s current standards means, by putting an emphasis on perception and almost spoon-feeding us readers to pick up on what he’s trying to imply by using Sammy to illustrate it all. The paper-thin storyline consisting of what Sammy is going through by narrating and the other, which is the main story being Sammy and the girls representing freedom and non-conformity from a neutral point of view versus what Lengel, the shoppers, and the storefront itself represent as being the socially correct status quo and policy we hold as normal living in society. In this story the establishment that is the A&P itself, is portrayed as routine and monotonous as a market in the middle of town can possibly be. Updike made it so on purpose, to give us a neutral setting that synonymous with our reality and what we perceive as normal behavior in society. The A&P is acceptable as a run-of-the-mill chain market, this character represents the status quo of a 1st world society where one is judged instantly for......

A&P Essay

...A&P In the story A&P by John Updike is about a Cashier named Sammy who works in a grocery store named A&P, in the suburb of Boston during summertime, and having conflicts with these three girls in bikinis and his manager Lengel. In this story there three types of conflicts that occur in this story. One is “man vs. man”; When Sammy has an argument with Lengel (store manager). “Man vs. society”, when Sammy thinks badly about a grocery shopper. Then there’s “man vs. himself”, where Sammy thought what he was doing when he quitted. In the beginning of this story there was already a conflict where is “man vs. society”. Sammy (cashier) didn’t know if he rung up an item he was holding in his hands or not, so he rung it up again not knowing. Because of this the customer gets mad, so thinks badly about an old grocery shopper. He thought she’s one of these cash-register-watchers, a witch about fifty with rouge on her cheekbones and no eyebrows, and I know it made her day to trip me up. She'd been watching cash registers forty years and probably never seen a mistake before (A&P). He thought about this because of the fit that the customer gave him. Furthermore, there’s a conflict “man vs. man”. In the story there are three girls in bikinis who walk in to the A&P store to shop. They were causing trouble for the customers and the employee including Sammy. Later on Lengel comes into the store. So as manager he told the girls that there are inappropriately dress to......

Cowardice in a&P

...Ben Cowardice in A&P What Sammy does at the end of the short story, A&P, may sound heroic and valiant, but it was actually cowardly of him to quit his job. When the girls walk into the store, Sammy is taken aback by their beauty and later tries to stand up for them by quitting his job. It shows a lack of commitment if Sammy is that easily persuaded to quit his job. Although Sammy thinks of himself as the unexpected hero in the story, nevertheless, he is just a boy trying to impress some girls with his audacity. Sammy is cowardly because he is running from his problems: a bland life. Sammy doesn’t want to live a bland life; he is living a monotonous life as a clerk at a general store. Every single day he is stuck behind a cash register ringing people up. His town is nothing exciting, “we’re north of Boston and there’s people in this town haven’t seen the ocean for twenty years”(340). His town is a typical small village in New England. People congregate in the summer, but come winter and there is nobody around. He wants to escape the monotony of his career and his life, so when the girls come around, he is instantly thinking they live a more eclectic lifestyle, “I slid right down her voice into her living room. Her father and the other men were standing around in ice-cream coats and bow ties and the women were in sandals picking up herring snacks on toothpicks off a big glass plate and they were all holding drinks the color of water with olives and sprigs......
