Internship Report Essay Example for Free

Internship Report Essay I am Nigel Ng Ding Xun from Business Information Technology. During the ending of my second year in Ngee Ann Polytechnic, I had to go through what may be the toughest thing I faced during my time studying in Ngee Ann. Internship. I was placed in the company Lau Chin Huat Co. Lau Chin Huat Co. is a firm of certified public accountants. In the company, there are a total of three different departments. The IT department, the Accounts department, and the Audit department. The head of the IT department is my supervisor, Mr Anthony Lum. He is the one that handles any of the IT problems faced in the company. Staffs in the company often treat him as the ‘boss’, as Mr Lau is not in the company most of the time. Mr Anthony is very strict when it comes to work. He is known as one who would get displeased very easily when a work given by him to his staffs is not completed on time even though the time given may not be sufficient. Therefore, most of his co-workers tend to panic and put in their utmost effort into completing their work efficiently. The Accounts and Audit departments are managed by mainly Mr Yeo, and Miss Ai Ting. They might be my superiors, but when working there, I could sense the amount of respect they have for all of their staffs, regardless of their status in the company. Due to that, many of the staffs deeply respect them, including me. The Audit Department performs audit work on client’s financial statements and records. They assist in preparation of audit working papers of clients to facilitate further audit work, and the prepare audit reports for review by audit work. They are not in the company most of the time as they are often off to another company for auditing of work. The Organisational Chart for Lau Chin Huat Co: Lau Chin Huat uses mainly two kinds of software to run their business, it being Adagio and OpenOffice. Adagio itself has many different kinds of products, but the products that Lau Chin Huat uses would be mainly focused on Adagio Payables, Adagio receivables, and Adagio Ledger. With these softwares combined, you can complete accounts payables, receivables and General Ledger management for your business. Open Office is just like Microsoft Office, just that it does not cost a single cent and that it is free for everyone to use. During my first week at Lau Chin Huat, I was told to do a descriptive and pictorial step by step user manual of the software, Adagio. It basically meant that I had to take screenshots of every step of the process, combine it into one or two pictures, and describe what it was for. Although it was time consuming, it was really useful to me in the sense that I had a better understanding on how to use Adagio after finishing the user manual. Moving on, during the third week of my internship, I was exposed to excel and its formulas. Using formulas would promote ease of access as users would not need to manually key in the data needed anymore. Just a click and drag would solve all those issues. I was also given easier kind of work, such as editing templates that would be used as receipts. I learnt how to conduct stock take, and I also had to key in the stock count of the companies who have already conducted their stock take. As it has always been my dream to work in an accounting firm, I found much joy while doing the work needed at Lau Chin Huat. The one thing that I really love when I was working at Lau Chin Huat would be that my co-workers are really friendly. As almost half of the company comprises of interns like myself, it was really easy to get along with them. To my surprise, even those that are working as full-timers are really friendly as well. Everyone will always lend a helping hand to you when in need, or when you are at doubt. During our lunch break, we would gather together and talk about anything and everything in the world. This is something that I really cherished and enjoyed during my 2 months of Internship at Lau Chin Huat. I could still remember my first few days where I knew no one and I felt really lonely during lunch breaks as I always had to dine alone. Until that day where one of my colleagues asked me whether I would like to join them for lunch. That really made my day. Till now, I could still clearly remember that situation and how elated I felt at that time. That made me realized how important it is to have friends in life. Though the working environment may be small, but everyone in the company is very bonded. We share everything with each other, and we treat each other as our own siblings. Although it sounds as though we will play around in the company, but when it comes to work, we put our heart and soul into producing efficient and quality work. During my first few weeks at Lau Chin Huat, I faced many problems/difficulties. To start it off, I admit that I was not happy at all being posted here. The travelling distance from my house to Lau Chin Huat was a long journey, I had the lowest pay amongst all my friends, and worst of all, I had to work on Saturdays. Being a comparative person, after I was told by my friends that my posting was the worst amongst all of them, I was really unhappy. I was really negative and it was not a good start for me on the first day I started working at Lau Chin Huat. I was easily affected during work, and little things that annoyed me just made me hated having my internship here even more. That was when I wanted to opt for a change of internship placement. It’s a long story, but basically, that step I made was the biggest mistake in the time of undertaking my Internship. I caused a lot of problems for everyone, and that mistake almost cost me to fail my Internship. Luckily, I was given a second chance by Lau Chin Huat, and I am really grateful to them for that. I was then asked to go in with a positive mindset and do the best that I can. I mean, after all, it’s just six weeks. How hard can it get, seriously. That sentence was told to me by my NPIS supervisor, Mr Tay. It really woke me up. It made a lot of sense to me, and I told myself to give it another shot. Apparently, my habit of not being able to be punctual was a major obstacle to overcome for me. I was late most of the time, and that feeling was really horrible. The stares given by others when you are late and you walk into the company. Sometimes, I just wish to bury my head under the ground. I felt so ashamed of myself, I was scolded by Mr Anthony and he was really unhappy. From that moment I told myself not to be late anymore, to wake up early to attend work on time. The first time when I was punctual actually felt really great. I did not have to rush to work, I was not panicking about how I should explain to my boss about why I am late, and I was praised by Mr Anthony for being punctual. I was happy. That was when I started waking up earlier, just so that I would arrive to work on time. There were many times when I faced difficulties in completing my work, as the task given to me was kind of ‘impossible’. There was this once where I was given this Excel file and I was supposed to derive with formulas in order for easier formatting of data. Everything was a breeze and I did not face any difficulties until this one cell where I was supposed to format cells according to their address. (Eg. Block 340; one cell. Ang Mo Kio Avenue 2; one cell.) Due to the different formatting of data in the database, I was unable to derive with this particular formula. All of my time was then spent on looking for ways to come out with the formula, researching on whether there are such formulas, but to no avail. When I told Mr Anthony about it, he told me that he would fail me for this because if I could not find the formula, the work would not be counted as complete, and he grades me based on the results produced. That was when I really panicked and I was really upset. Thankfully, Mr Yeo knew about the plight I was in and he told Mr Anthony that it was not fair for me and asked him to give me simpler work instead. Knowing that I was given a second chance, I tried even harder so that the work that I produced would be up to Mr Anthony’s standard. On the last day of my work, I realized that Mr Anthony is not such a bad guy after all. He had a talk with me before I left the company. He explained to me the reasons why it seemed like he was always picking on me. He told me that in the past, he was just like me. Always being late, and that he did not give a care in the world. Thankfully, his supervisor talked to him and changed the way of how he saw things. Now, that he realized the amount of similarity that we used to have, he told himself that he just wanted to show me the way of life, just like how his supervisor did for him. He told me that he knows that I did my best, and he was proud of me. These words that he said are words that I will never forget. During my time at Lau Chin Huat, it really taught me the importance of responsibility, punctuality and respect. I was always late and I did not bother whether about punctuality at all, but after being posted to Lau Chin Huat, I realized how important punctuality really is, be it work, or anything else you do. It is able to see a person’s level of responsibility just by whether they are punctual or not. I also realized that respect is not necessarily always given to others, it will only be given to those who deserve it. These are qualities being taught to me that I will carry with me wherever I am, be it when I am working, or when I am doing other things. My suggestions to improve the work done would be to always do things with a positive mindset and to persevere on in whatever you do. With a positive mindset and perseverance, no matter how tough your work is, a positive mindset will guide you through the way and your perseverance will make sure you see it to the end. To me, I think that these are the qualities everyone should have as this will help and benefit you in whatever you do. In conclusion, having my Internship at Lau Chin Huat taught me more Excel formulas that I would be able to use in my course of study, it also taught me how to do reports after a stock take. Internship taught me many valuable life lessons. I am really glad that I gave my all during the second chance that was given to me. If given the chance to, I would be more than happy to work for Lau Chin Huat again.

The Migration and Assimilation of Mexican Americans Essay Example for Free

The Migration and Assimilation of Mexican Americans Essay The migration of Mexican Americans has been a long journey. The road in which most have taken is one of sacrifice and hard-work. A road paved with the dreams and hopes, faith, determination, and the forbearance to achieve all that this land has to offer. The subject to be discussed is how Mexican Americans have migrated and how they were assimilated into â€Å"American† society. The history of Mexican Americans migration dates back to the twentieth century, which are closely associated to the growth of the railroads and irrigated agriculture. Economic conditions in Mexico caused hundreds of thousands of Mexicans to make new beginnings in the United States in the years from 1917 to the outbreak of the Great Depression in 1929 (Compean, n. d. ). Because of the expansion of sugar beets in Idaho, many Mexican migrant workers were recruited to the basin of the Columbia River. An increase in the demand for labor was seen when recruiters for the railroad companies and agriculture started to move out to the southwestern states and the borders cities in northern Mexico because many Mexicans voluntarily enrolled to find employment and a better life in the United States (Compean, n.d. ). On the other hand, many traveled to the areas of Oregon, Idaho, and Washington on their own because they received word about work opportunities. However, The Great Depression drastically slowed Mexican migration to those regions, but it did not fully come to a halt. Agriculture started to increase in volume because of World War II coming into place and so the demand for labor also increased. Recruiters, again, went in search for Mexicans and Mexican Americans to work the fields. Thousands from the regions of northern Mexico and the Southwest responded to this call to engage in hard and unceasingly hard work in the fields and orchards. At this time the federal government also joined in this struggle by coming to an agreement with Mexico to import Mexican contract workers, who became known as braceros, to harvest crops in the Pacific Northwest and other regions of the country (Compean, n. d. ). Many criticized the Bracero program indicating that it was an indentured alien program and a system of cross-border labor exploitation. Many Mexicans and Mexican Americans were not all eligible for the Bracero Program. Only healthy, landless, and surplus male agricultural workers from regions not experiencing a shortage in labor were allowed to be part of the Bracero Program contract (Hernandez, 2009). In the post-World War II years that the agricultural work opportunities continued to increase and attract Mexicans and Mexican Americans to such states as Oregon, Idaho, and Washington. An increase in the Mexican American migrant â€Å"settling out† of the migrant stream to search for year-round employment and to establish roots close to where they worked was becoming more predominated. Many plants were erected providing more employment and education was also provided for their children. It could be clearly seen that an assimilation process was occurring because Mexican Americans were able to establish communities. As a subordinate group, they have taken on many similarities or characteristics of the dominant group. Religion-based celebrations and customs also encouraged ethnic fellowship and the continuity of Mexican culture among Mexican American communities in the Pacific Northwest. Many of the assimilated features among the Mexican American people were that of volunteer, cultural, and political associations, which has played an important role in the building Mexican American communities in the Columbia River Basin (Compean, n. d. ). Before 1970, a small amount of inhabitants with poor levels of education and discrimination prohibited many from any purposeful political participation in the community where they reside. Mexican Americans will continue striving to shape politics and in the Columbia River Basin as they become citizens. As second-generation descendants; Mexican Americans will continue to obtain education to have the opportunity for voting, erecting businesses, and to contribute important factors to the cultural life of the region. The Mexican American subordinate group has had a great deal an impact not just in the past but well into the present regarding the agricultural department here in the United States. Hernandez (2009) stated, â€Å"By the turn of the twenty-first century, over one hundred years of Mexican and Latino immigration had forged a large Hispanic population in the United States, which signified a fundamental shift in U. S. demographics and carried a significant impact upon American society and culture. However, the century of mass migration from Mexico and, more recently from Central America, was dictated by developments that spanned far beyond the borders of the United States. Uneven capitalist development and U. S. foreign policy framed the story of Latino immigration to the United States,† (pp. 28). References Compean, M. (n. d. ).

Compaction for Sustainability: Advantages and Disadvantages

Compaction for Sustainability: Advantages and Disadvantages In developed countries, sustainable development has become increasingly important due to increased public awareness and pressure to meet demand from population growth. Urban Form is defined by (RTPI, 2015) as Physical characteristics that make up built-up areas, such as shape, size and density. It can be classified into four categories: Centralisation, Decentralisation, Concentration and Sprawl(Holden, 2004). Compaction (Centralisation and concentration) has been an EU policy since 1992 hence most European cities are densely populated. The aim is to develop sustainability which is defined by the Brundtland Commission as Meeting the needs of the present, without compromising the ability of future generation to meet their own needs. This can be considered from four dimensions: Economic, Social, Natural and Political (UNESCO, 2010). The essay will first focus on the advantages and disadvantages of compaction in relation to different dimensions of sustainability, then focus on alternativ e forms. Finally, concluding the best option and consider future challenges. Compaction will benefit cities economically due to the agglomeration effect where the concentration of firms allow them to benefit from the economies of scale hence reducing the cost of operation and the infrastructure cost. Also, it encourages more specialisation as higher density has higher demand which allows more division of labour (Tejvan, 2012). This means the population would have access to a wider range of services and job opportunities, hence more likely to receive a more reliable income and become economically sustainable. A compact city will make public transport more attractive as there is a higher demand and usage which allow prices to be more affordable and higher frequency services to be run. This will increase accessibility which allows access to more job opportunities and essential services (RTPI, 2015). Socially, more people living closer together means that there is a higher chance that people are meeting with each other and communicate hence the chance of social exclusion is reduced and allow accumulation of social capital (Bramley et al., 2009).However, results from the survey suggest that medium density (Terraced Housing) is the best for social interaction. A higher density will have a negative effect. Compact living encourages mixed land use hence people would have easier access to services and job opportunities which will increase the quality of life and improve social sustainability. Finally, with reduced traffic volume as car ownership reduces, safety for pedestrians has increased especially with pedestrianisation schemes of centres making them vibrant again. Urban sprawl has been the strategy in most UK cities between the 1970s and 90s with the focus on out of town development (Williams, 2014). As economic and business growth contradicts with environmental sustainability, therefore activities have to be regulated by the government through legislation and documents such as Planning Policy Guidance (PPG). The three main arguments of environmental sustainability are related to land use, energy use and air quality. Land use will reduce by increasing density through building on brownfield sites so the countryside is protected. In 1947, the Green Belt is introduced as part of the Town and Country Planning Act and PPG2 which allows local authorities to set areas where development is prohibited on the outskirt of towns and cities. By 2010, around 13% of land in England is Green Belt (Communities and Local Government, 2010). Another supportive reason is the air quality will improve because of compaction mainly due to reduced car ownership as people will travel less with services close to where they live and work. Energy cost and consumption are estimated to be reduced as a result of denser living. However, there are a lot of argument and findings which suggest the benefit of compaction is over-emphasised. Because of the green belt, house prices have been unaffordable for many younger generation and lower income household. According to Halifax Bank since 1983, UK house prices has risen by 101% and 124% in London after taking into account of inflation (The Investor, 2012). The pressure to build more homes can be seen through the increase in approved planning permission to build on the green belt which rises from 2300 in 2009-10 to 12,000 in 2014-15 (Booth, 2017). The increase in house prices means that houses are segregated by income. Gentrification in the city centre can be seen in most UK cities where new houses are targeted for investors or the young affluent. People with lower income are forced to live in terrace housing outside of the city which are deprived and highly segregated by ethnic minorities which are both economically and socially unsustainable. The Green Belt als o force development to occur outside it hence increasing urban sprawl(Mace et al., 2016). For example, a lot of people commute from areas such as Redhill and Horsham which are just outside the Metropolitan Green Belt. This is not good in terms of reducing land use. Finally, government focus on compaction means that rural areas are left isolated as investment focus on towns and cities(Frey, 2003). Many villages lack basic services such as post office as more people move into cities, there is not enough demand to keep them operating. Compaction is also associated with an increase in stress level which will lead to poorer social ties in communities. The ease of access to shops and services means that time spent in the community is reduced and poorer safety perception due to distrust of neighbours and presence of more people. Hence (Bramley et al., 2009) found that residential satisfaction is low in compacted areas which is not socially sustainable. As the land value increases in the city centre, this means the availability of green spaces is at a premium hence environmental quality will decline as most areas will be concrete. Although congestion is reduced is surrounding area, traffic volume in the centre actually increases which means air quality in the city centre is worse and increase chances of respiratory disease (Echenique et al., 2012). Melia et al (2011) suggest the idea of paradox of intensification where doubling the density does not reduce the number of trips by half. For example, Gordon (1997) cited in Melia et al (2011) found that in England that doubling densities only leads to 7% decrease in miles travel to work. This is mainly due to the population increase in the area.Studies have found that compaction might not lead to a reduction in energy use. (Heinonen et al., 2011) found that in Helsinki that CO2 emission is higher in downtown area than suburbs. They conclude that this is due to a higher standard of living in the downtown and the increase in emissions is more than the effect of compaction. These examples suggest the environmental benefits of compaction could be overstated. An alternative urban form which can be considered is polycentric cities which are decentralised but concentrated. This is evolved from Howards idea of the Satellite or Garden City in the early 1900s where a centre city is surrounded by satellite cities which carry around 32,000 people each hence a medium density. These satellite cities are self-contained with services and workplace and connected with other cities by Rail links. It focuses on the symbiotic relationship with nature hence trying to achieve sustainability (Frey, 2003). It is very idealistic and only 2 garden cities were built in the UK which was not very successful as density is too low for self-sufficient economy and services. Another form is the Transit Oriented Development (Calthorpe, 1993 cited in Frey, 2003) which based development around a centre with public transport Hub which has rail links with a major city. The centre is an area for the community with low rise apartments in centre and terraces further away. Parks will be located further away from the centre. This type of development is also known as corridor growth hence a controlled way to limit urban sprawl and Copenhagens Finger Plan is a good example (see Figure 1). People can live in medium densities towns which have shops and services near the hub and have easy access to the countryside hence a sustainable form. However, the high house prices in the centre is still problematic. According to a study of 114 European Cities by Zoeteman et al (2016). It found that sustainability score of city improves up to 2 million inhabitants mainly due to economic sustainability. In cities that are larger than 250,000 people, ecological and social capital reduce. It concludes the ideal size of 100,000-250,000 inhabitants which is a medium density. Therefore, it seems that future growth strategy should focus on developing polycentric medium density cities which is well connected by Public Transport along with technological innovation to reduce environmental pollution. This is a compromise between a centralised compact city and dispersed development. Current research shows that there is no consensus on whether compaction will benefit socially and environmentally. However, as most governments currently prioritise economic growth, the benefit of agglomeration means that compaction will likely to continue. Ideally, a polycentric network of medium density cities will achieve all forms of sustainability the best. Booth, R. 2017. English green belt set to get 360,000 new homes. The Guardian.

Abortion Essay -- essays research papers

Abortion is one of the most controversial issues in America today. Abortion is the ending of pregnancy before birth. There are approximately 1.5 million abortions every year in this country. Abortion was made legal in the 1970s. However, pro-life activists argue that it is murder. Should the government have the legal power to take away a woman\'s right to make decisions regarding her own body? An abortion results in the death of an embryo or a fetus. Abortion destroys the lives of helpless, innocent children. In many countries abortion is illegal. By aborting these unborn infants, humans are hurting themselves; they are not allowing themselves to meet these new identities and unique personalities. Abortion is very simply wrong. Everyone is raised knowing the difference between right and wrong. Murder is wrong, so why is not abortion? People argue that it is not murder if the child is unborn. Abortion is murder since the fetus being destroyed is living, growing and moving. Why is it that if an infant is destroyed months before the birth, there is no problem, but if killed a month after birth, this is inhumane murder? Everyday, innocent, harmless fetuses that could soon be laughing children are being cruelly destroyed. One form of abortion is to cut the fetus into pieces with serrated forceps before being removed, piece-by-piece from the uterus by suction with a vacuum aspirator. Another form consists of bringing the fetus feet first into the birth canal, puncturing its skull with a sharp instrument and sucking out the brain tissue. The remains of the fetus or embryo, as the case may be, are put into plastic buckets and then sent to a dumpster where these precious bones and limbs are disposed. However, how and when an abortion takes place are of little significance to pro- abortionists and other defenders of abortion. Even former abortion practitioners have a new view on abortion. These changes of heart were caused by psychological, religious and scientific reasons. One doctor, Dr. Bernard Nathanson, performed 60,000 abortions and supervised 10,000. Scientific evidence and the use of an ultrasound convinced him he was promoting and participating what he now calls â€Å"the most atrocious holocaust in the history of the United States.† Other doctors refuse to perform legal abortions, saying they should save lives rather than destroy them. Abortion becomes particu... ... life movement will win, because when you hold up a picture of a six month old fetus being stabbed in the neck and all you say is ’choice, choice, choice’ you are going to loose.† In conclusion, a women’s right to choose can justify abortion, but it should be banned because it\'s immoral and life begins at conception. Women have been given the right to have an abortion under the United States Constitution, but this right is still being protested by the people that fight for the unborn\'s rights. It is immoral because it is simply defined as murder. Life begins at conception not at birth. Before a child is born it is given all its supplies to survive. Before birth the child’s heart beats, all its necessary organs have been made present, and gastric juices flow in the stomach. This is a child that dreams, feels pain, and thinks. Some women may look at having an abortion to solve personal conflicts, but in all, women that chose abortion are abandoning their strengths of creation, compassion, and ability to be a mother. After evaluating each side, especially that of the pro-choice movement, and debating each side, I feel pro-life is the movement I st ick with in most circumstances.

Alexander the Great Essay -- essays research papers

Alexander was born in July 356 B.C. to Philip II and his third wife, Olympias. The parents were far from a happy couple, and Alexander was raised primarily under the influence of his mother. At the age of thirteen, he was sent to study with Aristotle—an education that was for the most part formal. Aristotle promoted the belief that non-Greeks were naturally slaves, thus encouraging the prince's thirst for conquest. Ultimately, however, Alexander would reject this belief, at least implicitly, as he attempted to cooperate with the Persians even as he subjugated them. Returning to Macedonia after three years, Alexander soon had the opportunity to prove his strength in battle, as he subdued rebellions and contributed to his father's famous victory over Athens and Thebes at Chaeronea. But when Philip divorced Olympias and married Cleopatra, Alexander began to fear that his father was looking for a new heir, and the father and son had a falling out. Their dispute was shortly resolved, but both remained suspicious of the other. Indeed, Philip was soon assassinated by a guard who presumably had a personal grievance, though Alexander and his mother are traditionally thought to have played some kind of role in Philip's death. Alexander thus succeeded to the throne and began the inevitable dynastic purging of enemies. At the same time, he had to force the other Greek city-states to acknowledge his authority as Hegemon of the Hellenic League, which Philip had established. In doing so,...

A critical analysis of The Great Gatsby Essay

It is all useless. It is like chasing the wind.† (Ecclesiastes 2:26). The â€Å"it† in this case, F Scott Fitzgerald’s groundbreaking novel The Great Gatsby, refers to the exhaustive efforts Gatsby undertakes in his quest for life: the life he wants to live, the so-called American Dream. The novel is Fitzgerald’s vessel of commentary and criticism of the American Dream. As he paints a vivid portrait of the Jazz Age, Fitzgerald defines this Dream, and through Gatsby’s downfall, expresses the futility and agony of its pursuit. Through Gatsby’s longing for it, he depicts its beauty and irresistible lure in a manner of which the Philosopher himself would be proud. The aspects of the American Dream are evident throughout Fitzgerald’s narrative. Take, for example, James Gatz’s heavenly, almost unbelievable rise from â€Å"beating his way along the south shore of Lake Superior as a clam-digger and a salmon-fisher† (Fitzgerald 95) to the great, i.e. excessive, Gatsby, housed in â€Å"a colossal affair by any standard†¦ with a tower on one side†¦ a marble swimming pool, and more than forty acres of lawn and garden† (Fitzgerald 11). The awe in which Fitzgerald presents his awakened phoenix clearly conveys the importance of improvement, or at least what one thinks is improvement, in the American Dream; it is not necessarily a life of excesses and wealth Fitzgerald defends as the Dream, for the audience sees clearly their detriments in the novel through Tom and Daisy, but rather a change in the style of life, reflecting the equally-American pioneering spirit. Nevertheless, wealth does certainly play an important role in the American Dream. With wealth, supposedly, comes comfort, as Nick mentions regarding his home: â€Å"I had a view of the water, a partial view of my neighbour’s lawn, and the consoling proximity of millionaires† (Fitzgerald 11). Wealth, states Ross Possnock in his quoting of Karl Marx, is the great equalizer of inequality: I am ugly, but I can buy the most beautiful woman for myself. Consequently, I am not ugly, for the effect of my ugliness, its power to repel, is annulled by money†¦ does not my money, therefore, transform all my incapacities into their opposites? (Possnock 204). Read Also:  Critical Response Essay Topics Gatsby’s incapacities, generally of an emotional nature, inhibitions preventing his successful capture of his long-lost love, Daisy, are washed away with the drunkenness provided by the dollar: However glorious might be his future as Jay Gatsby, he was a present a penniless young man without a past, and at any moment the invisible cloak of his uniform might slip from his shoulders†¦ He took what he could get, ravenously and unscrupulously – eventually he took Daisy one still October night (Fitzgerald 141). Once armed with the lucre, however, he is prepared to contribute equally to the relationship, making it truly an equal relation of love. Love represents the other side of the coin of wealth: as opposed to material wealth, it refers instead to emotional wealth. Whatever its plane of existence, love plays a pivotal role in the American Dream, in Gatsby’s Dream. Perhaps love is the most valuable of the aspects presented thus far of the Dream; â€Å"He hadn’t once ceased looking at Daisy, and I think he revalued everything in his house according to the measure of response it drew from her well-loved eyes† (Fitzgerald 88). Such is his love for her; the bootlegging Gatsby values this emotional wealth to the extent that he essentially abandons the material for just a moment, losing himself in the winds of passion stirred up by the swaying of Daisy’s dress as she inspects Gatsby’s lookout tower for the green light. His emotional wealth is so suddenly multiplied that â€Å"none of it [his possessions] was any longer real. Once he nearly toppled down a flight of stairs† (Fitzgerald 88). Sharing the same side of the coin is the need for social acceptance. Gatsby prides himself on his openness; his lavish parties where strangers â€Å"came and went without having met Gatsby at all, came for the party with a simplicity of heart that was its own ticket of admission† (Fitzgerald 43), proof of not only his tolerance, but also of his acceptance of those whose drinking make him grow â€Å"more correct as the fraternal hilarity increased† (Fitzgerald 51). Gatsby certainly wants the people on his side: from his house labeled a  Norman â€Å"Hotel de Ville,† or City Hall, open to the public, to Lucille’s replacement dress from Croirier’s, courtesy of Gatsby, no expense is too great in his quest to win others support. Gatsby needs as much popular support as he can get, in the face of such random acts of contempt as â€Å"he killed a man once† (Fitzgerald 45) to â€Å"he was a German spy during the war† (Fitzgerald 45). Improvement, wealth, love, popularity: all contribute to the definition of the American Dream. What is missing from the preceding list is, however, perhaps the most important quality of all: that the American Dream is exactly that, a mere dream. â€Å"Our eyes can never see enough to be satisfied; our ears can never hear enough† (Ecclesiastes 1:8). The key words here are â€Å"never† and â€Å"satisfied†; it is the essence of the American Dream, satisfaction. Unfortunately, the quest for satisfaction and happiness is unending, like eternally chasing one’s tail; hence the â€Å"never.† It is a vicious circle, one of many traps laid out by Fitzgerald for the sake of educating his audience of the perils of imagination. Indeed, given the thin line between the intrinsic desire for self-improvement and the waste and futility of pursuing mental illusions, and the consequences of the latter, the peril is quite extreme. Esteemed Gatsby inquisitor Marius Bewley succinctly defines the American Dream as â€Å"life on a level at which the material and the spiritual [i.e. imaginary] have become inextricably confused,† (Bewley 37) whose â€Å"blackest devils [are] limit and deprivation† (Bewley 38). Higher and higher the summit of its ideals climb, until surely and eventually the mountain becomes insurmountable for mortal man. â€Å"What has happened before will happen again. What has been done before will be done again† (Ecclesiastes 1:9). Such is Gatsby’s battle cry as he marches off on a mission to re-discover, or rather to re-implant, the passion he found years earlier in the person of Daisy: † ‘Can’t repeat the past?’ he cried incredulously. ‘Why of course you can!†¦ I’m going to fix everything just the way is was before,’ he said, nodding determinedly. ‘She’ll [Daisy] see’ † (Fitzgerald 106). So begins the heartbreaking circle which started on that selfish day â€Å"in the middle of spring with the arrival of Tom Buchanan†¦ The letter reached Gatsby while he was still at Oxford†Ã‚  (Fitzgerald 144). Just as Daisy re-enters Gatsby’s life and sets the circle moving, does she fulfill the reverse: she, in an equally shocking and abrupt manner, flees Gatsby, his eyes still scintillating in the reflection of the Dream, thus bringing this aspect full-circle and pounding in the first nail in the Dream’s coffin. The second nail to further seal the coffin is the revolving door quality of the rise and fall from rich to poor as the pocketbooks of the Dreamers lines with money, their moral character is chipped away. Once the conscience is destroyed, one can predict that as the money runs out, character returns. Proof of this circle is offered towards the end of the novel: heading back into East Egg from the city after a tense incident on a scorching summer’s day, Gatsby and Daisy spend their last moments together in the car; upon her return to East Egg, Daisy, Gatsby’s most valued possession, the standard against which â€Å"he revalued everything in his house† (Fitzgerald 88) leaves him and returns fully to Tom, thus leaving Gatsby â€Å"bankrupt.† As this decision transpires, Gatsby selflessly accepts the blame for the accident where Daisy, in control of the car, is at fault. Given the sheer number of its examples, the lack of morals in the materially-rich is indeed an element Fitzgerald wished to impress upon his audience. The lack of respect for life present in high society is demonstrated most strongly by Daisy’s relationship, or lack thereof, with her daughter, Pammy. Appearing only once or twice in the novel, Pammy’s non-existent role in the plot and Daisy’s life prove Daisy’s misplaced priorities as a mother and as a â€Å"successful† American Dreamer. Neglect becomes synonymous with high society in Chapter II; Myrtle’s Airedale, referred to simply as one of Mrs. Wilson’s â€Å"other purchases† (Fitzgerald 31), is last seen â€Å"sitting on the table with blind eyes through the smoke, and from time to time groaning faintly† (Fitzgerald 38) as â€Å"people disappeared, reappeared, made plans to go somewhere† (Fitzgerald 38). By the end of the book Pammy and the dog (Myrtle doesn’t even bother naming him)  are forgotten, victims of the American Dreamers’ quest for happiness. Daisy’s whims wreak havoc on other’s lives as she continues her quest for â€Å"happiness,† driving Gatsby’s car at supersonic speeds, plowing through Myrtle Wilson’s body†¦ and not even bothering to stop. Not only does she continue without batting an eye, Daisy allows Gatsby to essentially hang for her crimes without a simple â€Å"I’m sorry† or a token â€Å"I love you.† Tom, for his part, forgets the woman in favour of whom he cheats on Daisy. â€Å"There was an unmistakable air of natural intimacy about the picture, and anybody would have said that they were conspiring together† (Fitzgerald 138). Fitzgerald sums up his judgement of the financially-superior/morally-inferior: They were careless people†¦ they smashed up things and creatures and then retreated back into their money or their vast carelessness, or whatever it was that kept them together, and let other people clean up the mess they had made (Fitzgerald 170). The mess they had made; the heaps of ashes left in their wake. Unfortunately, dreams don’t come cheap. Nor do they come without work. The dreams achieved by high society, such as the creation of the enclave known as East Egg, are built, as Marx would say, on the backs of the workers; the workers who sweat and toil for the benefit of the American Dreamers (or perhaps to join their ranks) creating and living in the vast ashheaps of America, separate from their economic rulers. They do not live the Dream; they don’t have the opportunity to. This exclusionary characteristic of the American Dream appears as the distinct snobbery evident through East Egg’s assertion of â€Å"membership in a rather distinguished secret society† (Fitzgerald 22). From â€Å"I [Nick] lived at West Egg, the – well, the less-fashionable of the two† (Fitzgerald 10), to † ‘my opinion on these matters is final,’ he [Tom] seemed to say, ‘just because I’m stronger and more of a man than you are’ † (Fitzgerald 13), to â€Å"Tom†¦ deferred to the sensibilities of those East Eggers who might be on the train† (Fitzgerald 29), it certainly seems that East Egg suffers from a superiority complex: a condition due, no doubt, to their â€Å"success† in embodying the American Dream. â€Å"So I realized that all we can do is be happy, and do the best we can while we are still alive† (Ecclesiastes 3:12). The beauty of the American Dream is that, as an unattainable yet seemingly plausible goal for all intents and purposes, it continues to inspire humanity of all nationalities to stretch to a new level of existence, regardless of their current social status. The quest for happiness is perhaps the most venerable of all human institutions due to the natural human desire for a hedonistic existence: a simple pursuit, hardly; a palpable pursuit, possibly; a consuming pursuit, definitely. While the pursuit of the American Dream can easily be branded selfish and greedy, one must admire those American Dreamers with the gall to embark on its realization. The lengths to which Gatsby goes to bring his world to fruition are, to say the least, extensive. An example is his building of â€Å"gonnegtions† with less than scrupulous business partners to finance the erection of a tower from which to gaze at a green light, a task requiring years of work, as his partner Meyer Wolfshiem reminisces: † ‘My memory goes back to when I first met him [Gatsby]’, he said. ‘A young major just out of†¦ the war [1918].’†¦ ‘Did you start him in business,’ I [Nick] inquired. ‘Start him! I made him’ † (Fitzgerald 162). While one might criticize his hyperactive imagination and perhaps even his sanity, one must grant him credit for his seemingly innocent and juvenile idealism; he is a true romantic. One must also admire his tenacity and strength of will: where lesser men would have collapsed under the strain of reality, the strong Gatsby persevered against all odds and, for a moment, held â€Å"Daisy’s white face† (Fitzgerald 107) and â€Å"she blossomed for him like a flower and the incarnation was complete† (Fitzgerald 107). The facing of such a challenge is no less heroic than catching a marlin or warding off a raging bull: all three require intense mental preparation, and though each expends different physical force, all three leave the hero exhausted physically and emotionally. Where Gatsby’s inferiors depend on alcohol to wash away their inhibitions and uncertainties – â€Å"Never had a drink before, but oh how I [Daisy] enjoy it† (Fitzgerald 74) declares a drunken, uncertain,  about-to-be-married Daisy in the face of mounting stress and anxiety over her commitment; or â€Å"the bottle of whiskey – a second one – [which] was in constant demand by all present† (Fitzgerald 37) at the heated scrutinize-Tom’s-relationships meeting in Tom’s/Myrtle’s apartment – Gatsby charges headfirst, conscious without anaesthetic, straight into the source of potential joy – and potential heartbreak. â€Å"I [Nick] wondered if the fact that he [Gatsby] was not drinking helped to set him off from his guests, for it seemed to me that he grew more correct as the†¦ hilarity increased† (Fitzgerald 51). The pathetic hilarity with which the novel ends – with Gatsby dead, sincerely believing that Daisy will call back, and Tom and Daisy continuing on, living without memory of their brief affairs of the summer of 1922 – accomplishes two things: firstly, it validates Gatsby and the American Dream; Fitzgerald contrasts the unforgivable, despicable actions of Tom and Daisy with the seemingly innocent and juvenile fantasies of Gatsby. The latter earns the audience’s sympathy, while the former are condemned for their inhumanity. Secondly, it debunks the American Dream: in spite of all the efforts and labours Gatsby invests to bring his Dream to fruition, he and his bold vision are cut short, left to rot floating in a pool of blood, rejected by reality; a strong message that material existence does not take kindly to Dreamers. And the battle returns to its origin; Dreamers recommence their offensive, reality braces itself; and the story continues. â€Å"It is all useless. It is like chasing the wind† (Ecclesiastes 2:26).
