The Chimney Sweeper and London by William Blake and Tich...

The two poems â€Å"The Chimney Sweeper† and â€Å"London† by William Blake, and the two poems â€Å"Tich Miller† and â€Å"Timothy Winters† are all on a theme of childhood, however, they are set in different eras and so childhood should be very different. Discuss this, comparing and contrasting the poems. As a child, William Blake was a loner. He never socialised with other children and sat by himself reading the Bible. His family were very religious, but did not agree with organised religion. This meant that they never went to church and did all their worshipping at home. Blake was always an outsider and he refused to join in with his brothers and sisters. He had visions of angels and God when he was young and he often thought that this†¦show more content†¦This line also gives the impression of a prison and people being behind bars. This is because Blake didn’t like authority and believed in free will. The poem has a very strong rhythm, this sounds like either the Industrial Revolution or Blake’s’ fist on a table in anger. â€Å"And blights with plagues the Marriage hearse† In this last line of the poem, Blake puts two opposing ideas in a sentence. It puts a whole different view on marriage, making it seem like the beginning is the start of the end. Blake sees life in London very depressing; this could be why he thinks that marriage is like death. Living in a place like London could lead to hatred and end up not being, hence, the end of a marriage, a funeral. Blake is appalled by the cruelty to children that is going on. He mentions â€Å"Infants† twice in the poem, both saying that they are crying. â€Å"How the youthful Harlot’s curse Blasts the new born Infants tear† This shows that there were a lot of unwanted children at the time because of prostitution at a young age. The fact that young girls were on the streets also shows that life was hard because they were not being kept at home, or were sent out to get money for the family, and this was their last resort. In the poem â€Å"The Chimney Sweeper† Blake describes the life of a young boy who is a chimney sweeper. In the first

Proposed Merger Between Staples And Office Depot - 972 Words

Anticompetitive Effects and Price Effects: Proposed Merger between Staples and Office Depot (1997) Xueqi Ji 6252074952 Abstract FTC employed structural, documentary, statistical, econometrics and financial evidence to verify that the proposed merger of Staples and Office Depot will lead to increase in market concentration, market prices and stock prices, and thus support FTC’s contention that this merger will cause an anticompetitive effect on Office Superstore market. Staples and Office Depot made a plain and useless contradiction. Finally, the Court announced to agree with FTC, and granted a preliminary injunction on this merger. This paper mainly focuses on FTC’s evidence and analysis. Keywords: antitrust, horizontal merger,†¦show more content†¦Staples (2006), Orley Ashenfelter, David Ashmore, Johnathon B. Baker, Suzanne Gleason and Daniel S. Hosken leveraged extensive public record to provide a detailed discussion of the econometric models used in this merging case and to show how differences between the models led to the discrepancy between these estimates. FTC claimed that based on various analysis and evidence, proposed merger between Staples and Office Depot will harm competition in office superstore chain market and raise market price which will lessen customers’ welfare. Nevertheless, two parties of merger casted doubt on every detailed statement, and interpreted that this merger will reduce costs, broaden scale of economies, improve economic efficiency, and optimize resource allocation, and then lower market price efficiently. Finally, the Court chose to agree with FTC’s contention. II.Background In 1996, there were three largest and absolutely dominant office superstores (OSS) chains in United States office supply market, Staples, Office Depot and OfficeMax. Office superstores can get access to much more convenient and cheaper supply of goods than small retailers through signing a mass of contracts with suppliers.

Profit Host Country Also Gets Privileged †Myassignmrnthelp.Com

Question: Discuss About The Profit And Host Country Also Gets Privileged? Answer: Introduction Adidas was one of the key partners of FIFA world cup 2014 which was held in Brazil. Creating the new is the tagline for their next five- year strategic business plan. This attitude has led them to their current position and will pave the way for an exciting future. This is because the industry of sports tourism products is expanding and will continue to do so. It is expanding at a rapid speed as compared to other industries which includes consumer electronics too. Sports form the centre of all culture and society and the root to an individuals health and happiness. This is an excellent platform for Adidas because they will get the opportunity to excel in their business. They have become successful in changing the lives of people through their power in sports. They work hard to inspire and motivate people to indulge in sporting activities. They are also successful in transferring their competence in sports into fashion, style statement and street wear as they believe that sports are l ife and attitude. Their mission and vision is totally aimed at sports (Billings, Burch and Zimmerman 2015). The event It was the 20th FIFA world cup that was held in Brazil in 2014. The one- month long event was held after Peles country was permitted to organize the event. Thirty-one teams went forward for the qualifying rounds to join the host country in the final show. 64 matches were played in total 12 venues of Brazil. It was the first time in an event that the officials used goal- line technology and vanishing foam for free kicks. The gathering for the grand event crossed 1 million who came from 202 different countries. All the popular and world- cup winning teams had qualified for the match. In the semi- final the host nation had to bid farewell after losing to Germany who played against Argentina in the final (Clemente et al. 2015). The match against Argentina and Germany turned out to be a battle between Lionel Messi of Argentina and Thomas Muller of Germany. Both of them had put their utmost effort to kiss the cup at the end. As the star shines for only one, Germany became the first ever Eu ropean team to take home the gorgeous World cup. FIFA had organized FIFA Fan Fests in all the 12 venues throughout the competition. In order to avoid ghost goals, there was an introduction of goal line technology in the 2014 world cup. There were 14 high speed cameras, out of which 7 were faced towards the goals. Adidas Brazuca was the official ball in the match which was supplied by Forward Sports of Sialkot. Fuleco, a three-banded armadillo was the mascot in this match after three- month long election process. Lionel Messi won the golden ball and Thomas Muller was awarded the silver ball while Manuel Neuer got the golden glove and James Rodriguez won the golden boot for being the top goal scorer (Cotta, et al. 2013). Bottom line of the event Globo Marcas was appointed as the main licensee by FIFA for supplying the retail products of 2014 world cup. The global audience in the events of the entire grand event is regarded as goldmines by the corporations and the official sponsors of the tournament. The major partners of FIFA such as Adidas, Coca- cola, Emirates, Hyundai motor group, Sony and Visa pay approximately $25-50 million every year in addition to the sponsors. The international brands like Budweiser, Castrol, Continental, Johnson Johnson and McDonalds along with the European organic food producers like Moy Park, the telecom company of Brazil and Oi and Yingli Solar, the largest solar panel manufacturer in the world also contribute to the profit that is gained in the enormous event of FIFA world cup. In the previous year of the 2014 World cup, FIFA had gained $404 million from the marketers in association with the current year of world cup which made up to 29% of yearly revenue (Devlin and Billings 2016). All the co mpanies mentioned above have a place in the website of FIFA and in their promotional materials. According to authentic source, it is reported that the investment by companies have increased by 40% in four years from 2010- 14. Target segment It is hard for the authorities to win over the consumers and it is even harder to retain them. It is a totally new area of online consumer behavior in the recent years. Only the traditional form of market research has the ability to tell in this complex world of several platforms. For this reason the company SingTel had integrated its entire suite of analytics capabilities to provide the advertisers with a holistic viewpoint of consumer behavior during the 2014 FIFA World Cup. Being in the front line of broadcasters in the World Cup, the SingTel had intended to realize the behavior of the consumers by deducing at home, outside home and online (Gibson 2017). These ideas benefitted the advertisers as they were able to improve their marketing strategies, calculating their ROI and the activation and promotional investments in the world cup and recognize the promotional opportunities in the future on the basis of the behavior of their target audience during FIFA 2014. As the event was scr eened at the community centers, clubs, cafes, bars and restaurants, the analytics was in a special position to observe the real-time location data for understanding the demographics and habits of the viewers. Competitor analysis through 4Ps ICC and IOC are regarded as the competitors of FIFA. It is important to identify the current and future competitors in the market by analyzing the target products. It is also important to know the preference of consumers by recognizing their direct and indirect competition (Gibson et al. 2014). By knowing the market share of competitors, it will become easy for the promotion of the product. A small market research will find out the reason for sale in competition. The strengths and weaknesses will remain unknown until the idea of market share is gained. Planning and executing the proper strategies is beneficial for remaining in the competition or leaving the competitors behind. Either the same strategies can be used or new strategies can be introduced to make an impact on the pricing. Making a competition portfolio helps in identifying all the products of competitors, their logistics, tangible and intangible features and other services. At the same time, it is essential to prepare a s uitable place where the product can be used for sale and that will lead to its growth and expansion. A follow up is required for the qualitative and quantitative measures of the strategies (Hallmann, Dallmeyer and Breuer 2014). SWOT analysis FIFA, the governing body of soccer, is responsible for arranging the most spectacular sporting event in the planet, the Football World Cup. The event is targeted to all football lovers irrespective of the age and gender. They have been successfully organizing the Football World Cup for the last 80 years. Product positioning The biggest footwear and apparel brands in the event have rolled out their individual products to prepare for the market and product planning of world cup. Companies like Adidas are confident about gaining the soccer sales. For the sponsors, the battle of World cup helps in deciding who will get the throne in the international soccer sales in the coming years. They follow the strategy of underlining their consistent leading position to share the passion for football with fans all over the world. From being mere sponsors, Adidas has upgraded to being the official partner of FIFA. With the retirement of the Adidas- sponsored soccer super star David Beckham; they have planned to use the World Cup for getting the marketing ball in the flow for Lionel Messi. With the approach of World cup, NIKE had started giving new uniforms for its sponsored countries. Adidas officials have unanimously stated that they will hit the social media by broadcasting their world cup soccer messages (Hsu 2013). According to them, in that year the soccers advocates totally believed the refrain which repeated after every four years. It is said that the event of world cup is a marketing opportunity and marketing dreams for all those brands that are associated with this outstanding event. Competitive advantage The sustainability strategy and the strategic planning process are defined and selected through a materiality analysis. This analysis is regarded as the influence and relevance for the FIFA World cup and its stakeholders. The strategic objective is the root of this strategy. The stakeholders, goals for each issue and other individual activities will be implemented to attain those goals and the strategic objectives. Through the process of strategic planning, social responsibility and the environment were considered as the two main pillars of sustainable strategy (Kim et al. 2015). The areas that can be grouped under social responsibility are fair practices for operation, consumer issues, labor practices, and human rights along with involvement of community and their development. Moreover, community development is more connected with the prevalent global football where it was used to promote social changes in Brazil. The sustainability efforts of the FIFA world cup are guided by the th eories of transparency, accountability, respect and ethical behavior for the stakeholders interests, international behavioral policies, the rule of law and human rights. They will promote an advanced level of well being in the host countries by helping the initiatives that use football as a channel for development in the educational, health, civil security, social inclusion and anti- discrimination areas (Kim, Cheong and Kim 2016). For maintaining a successful corporation, FIFA has a well processed marketing mix which includes the 4Ps. The amalgamation of products, place, promotion and price attain the final outcome. The sponsors of FIFA such as Adidas, Coca- Cola, Emirates and others advertise FIFA on their products and vice- versa. It can be seen that the boundary of the field where the match was held were all covered with the name of the sponsors. The sharing of advertisement by both expands the number of consumers who can see the logo of the company in the area. FIFA actually makes the place where the companies can display their advertisement. This sets the instance of promotion strategy. It is seen that most of the sponsors are global brands. Since FIFA is international too, both of them have interests in common and influence the nations all over on a common ground. This reflects the place strategy. The pricing strategy becomes significant because soccer is the cheapest compared to any other games. It just requires a 15$ ball with the logo and other equipment at very minimal costs. There are still a lot of other products which are not so cheap so FIFA will hold world cups in such countries as to help their economy (Knott, Fyall and Jones 2015). Management structure A grand event like FIFA World Cup has several stakeholders all throughout the application, planning, preparation, execution process and the after effect. Stakeholders include everyone who will be affected by these processes. Therefore, it is important to recognize the stakeholders in order to have an idea about the management structure, those who will be affected by the event and to what extent. All the stakeholders are responsible for making the event successful but they must also be satisfied so that they cannot oppose the event. Apart from that, there are political considerations such as increasing national prestige and economic considerations are also important factors in motivating the states to host a major event. The high tourist flows as a result of such a grand event expects economic benefit. Tourists inflow helps in expansion of business in the hotel and hospitality sector. On the other hand, the increase in tourist inflow gives rise to the issue of workers in Brazil and th eir qualification to deal with such international tourists (Liu et al. 2015). Development of communications and the investment of media in the world cup is a prime long-term opportunity and play the pivotal role to pose an outstanding impact on the hosting of a great event and the reputation of the host country, Brazil. Three-year forecast It was predicted by the Brazils Ministry of Sports that the FIFA world cup 2014 is going to be a cash cow for them. The economy of the country is forecast to grow by a minimum of $70 billion as they had hosted the world cup event. The amount is based on the public and private investment of Brazil in infrastructure, increase in consumption and other activities in the services sector and in the collection of tax. The event is expected to earn more than $30 billion in through direct tax, $10 billion through indirect tax and an increase in the consumption of the local goods and services by approximately $3 billion for the time period of the event. 600000 tourists are expected to come to the venue which would generate an additional $2.5 billion for the countrys travel industry. More or less, 3 million Brazilian tourists are predicted to travel throughout the country to generate an amount of $3.5 billion for travel and tourism (Noel et al. 2017). Conclusion The use of three strategies by the sponsors in FIFA world cup 2014 made it a remarkable event to be remembered for four years. The speed of reaching the consumers, the location to expand market and inviting the sports person to be the partners of the brand provided a positive outlook and the opportunity to create something new. The three strategies were supplemented by highlighting on portfolio and corporate and digital culture. Sports tourism has come under the radar of tourism industry as a result of their economic forces, technological innovations and change in value and attitude. Although the sports tourism industry is restricted to certain areas but they can infiltrate economic, cultural and environmental areas.

The Glass Menagerie Essays (720 words) - English-language Films

The Glass Menagerie Symbolism in The Glass Menagerie- The play The Glass Menagerie, by Tennessee Williams, Williams uses many symbols which represent many different things. Many of the symbols used in the play try to symbolize some form of escape or difference between reality and illusion. The first symbol, presented in the first scene, is the fire escape. This represents the bridge between the illusory world of the Wingfields and the world of reality. This bridge seems to be a one way passage. But the direction varies for each character. For Tom, the fire escape is the way out of the world of Amanda and Laura and an entrance into the world of reality. For Laura, the fire escape is a way into her world. A way to escape from reality. Both examples can readily be seen: Tom will stand outside on the fire escape to smoke, showing that he does not like to be inside, to be a part of the illusionary world. Laura, on the other hand, thinks of the fire escape as a way in and not a way out. This can be seen when Amanda sends Laura to go to the store: Laura trips on the fire escape. This also shows that Laura's fears and emotions greatly affect her physical condition, more so than normal people. Another symbol presented deals more with Tom than any of the other characters: Tom's habit of going to the movies shows us his longing to leave the apartment and head out into the world of reality. A place where one can find adventure. And Tom, being a poet, can understand the needs of man to long for adventure and romance. But he is kept from entering reality by Amanda, who criticizes him as being a selfish dreamer. But, Tom has made steps to escape into reality by transferring the payment of a light bill to pay for his dues in the Merchant Seaman's Union. Another symbol, which deals with both Amanda and Laura, is Jim O'Connor. To Laura, Jim represents the one thing she fears and does not want to face, reality. Jim is a perfect example of the common man. A person with no real outstanding quality. In fact, Jim is rather awkward, which can be seen when he dances with Laura. To Amanda, Jim represents the days of her youth, when she went frolicking about picking jonquils and supposedly having seventeen gentlemen callers on one Sunday afternoon. Although Amanda desires to see Laura settled down with a nice young man, it is hard to tell whether she wanted a gentleman caller to be invited for Laura or for herself. One symbol which is rather obvious is Laura's glass menagerie. Her collection of glass represents her own private world. Set apart from reality, a place where she can hide and be safe. The events that happen to Laura's glass affects Laura's emotional state greatly. When Amanda tells Laura to practice typing, Laura instead plays with her glass. When Amanda is heard walking up the fire escape, she quickly hides her collection. She does this to hide her secret world from the others. When Tom leaves to go to the movies in an angered rush, he accidentally breaks some of Laura's glass. The shattered glass represents Laura's understanding of Tom's responsibilities to her. Also, the unicorn, which is important, represents Laura directly. Laura points out to Jim that the unicorn is different, just as she is different. She also points out that the unicorn does not complain of being different, as she does not complain either. And when Jim breaks the horn off the unicorn, Laura points out that now it is like the other horses, just as Laura has shed some of her shyness and become more normal. When she hands the broken unicorn to Jim, this might represent Laura handing over her broken love to Jim, as Jim has revealed that he is engaged to be married. As can be seen, there are quite a few symbols in this play. And a number of them have diverse meanings. Most of these symbols have a direct meaning in the author's own life. This is understandable seeing that the play is supposed

Euoplocephalus - Facts and Figures

Euoplocephalus - Facts and Figures Name: Euoplocephalus (Greek for well-armored head); pronounced YOU-oh-plo-SEFF-ah-luss Habitat: Woodlands of North America Historical Period: Late Cretaceous (75-65 million years ago) Size and Weight: About 20 feet long and two tons Diet: Plants Distinguishing Characteristics: Large spines on back; quadrupedal posture; clubbed tail; armored eyelids About Euoplocephalus Probably the most evolved, or derived, of all the ankylosaurs, or armored dinosaurs, Euoplocephalus was the Cretaceous equivalent of the Batmobile: this dinosaurs back, head and sides were completely armored, even its eyelids, and it wielded a prominent club on the end of its tail. One can imagine that the apex predators of late Cretaceous North America (such as Tyrannosaurus Rex) went after easier prey, since the only way to kill and eat a full-grown Euoplocephalus would be to somehow flip it onto its back and dig into its soft bellya process that might entail a few cuts and bruises, not to mention the occasional loss of limb. Although its close cousin Ankylosaurus gets all the press, Euoplocephalus is the best-known ankylosaur among paleontologists, thanks to the discovery of over 40 more-or-less complete fossil specimens (including about 15 intact skulls) in the American west. However, since the remains of multiple Euoplocephalus males, females, and juveniles have never been found heaped together, its likely that this plant-eater led a solitary lifestyle (though some experts hold out hope that Euoplocephalus roamed the North American plains in small herds, which would have afforded them an extra layer of protection against hungry tyrannosaurs and raptors). As well-attested as it is, theres still a lot about Euoplocephalus that we dont understand. For example, theres some debate about how usefully this dinosaur could wield its tail club in combat, and whether this was a defensive or offensive adaptation (one can imagine male Euoplocephalus bonking each other with their tail clubs during mating season, rather than trying to use them to intimidate a hungry Gorgosaurus). There are also some tantalizing hints that Euoplocephalus may not have been as slow and plodding a creature as its anatomy would indicate; perhaps it was able to charge at full speed when enraged, like an angry hippopotamus! Like many dinosaurs of North America, the type specimen of Euoplocephalus was discovered in Canada rather than the U.S., by the famous Canadian paleontologist Lawrence Lambe in 1897. (Lambe originally named his discovery Stereocephalus, Greek for solid head, but since this name turned out to be already preoccupied by another animal genus, he coined Euoplocephalus, well-armored head, in 1910.) Lambe also assigned Euoplocephalus to the stegosaur family, which was not quite as big a blunder as it may seem, since stegosaurs and ankylosaurs are both classified as thyreophoran dinosaurs and not as much was known about these armored plant-eaters 100 years ago as it is today.

The Science of Magnetic Field Lines

The Science of Magnetic Field Lines A magnetic field surrounds any electric charge in motion. The magnetic field is continuous and invisible, but its strength and orientation may be represented by magnetic field lines. Ideally, magnetic field lines or magnetic flux lines show the strength and orientation of a magnetic field. The representation is useful because it gives people a way to view an invisible force and because mathematical laws of physics easily accommodate the number or density of field lines. Magnetic field lines are a visual representation of the invisible lines of force in a magnetic field.By convention, the lines trace the force from the north to south pole of a magnet.The distance between the lines indicates relative strength of the magnetic field. The closer the lines are, the stronger the magnetic field is.Iron filings and a compass may be used to trace the shape, strength, and direction of magnetic field lines. A magnetic field is a vector, which means it has magnitude and direction. If electric current flows in a straight line, the right hand rule shows the direction invisible magnetic field lines flow around a wire. If you imagine gripping the wire with your right hand with your thumb pointing in the direction of the current, the magnetic field travels in the direction of the fingers around the wire. But, what if you dont know the direction of current or simply want to visualize a magnetic field? How to See a Magnetic Field Like air, a magnetic field is invisible. You can view wind indirectly by throwing small bits of paper into the air. Similarly, placing bits of magnetic material in a magnetic field lets you trace its path. Easy methods include: Use a Compass A group of compasses can show the directions of magnetic field lines. Maciej Frolow / Getty Images Waving a single compass around a magnetic field shows the direction of the field lines. To actually map the magnetic field, placing many compasses indicates the direction of the magnetic field at any point. To draw magnetic field lines, connect the compass dots. The advantage of this method is that it shows the direction of magnetic field lines. The disadvantage is that it doesnt indicate magnetic field strength. Use Iron Filings or Magnetite Sand Iron is ferromagnetic. This means it aligns itself along magnetic field lines, forming tiny magnets with north and south poles. Tiny bits of iron, such as iron filings, align to form a detailed map of field lines because the north pole of one piece orients to repel the north pole of another piece and attract its south pole. But, you cant just sprinkle the filings onto a magnet because they are attracted to it and will stick to it rather than trace the magnetic field. To solve this problem, iron filings are sprinkled onto paper or plastic over a magnetic field. One technique used to disperse the filings is to sprinkle them onto the surface from a height of a few inches. More filings can be added to make the field lines more clear, but only up to a point. Alternatives to iron filings include steel BB pellets, tin-plated iron filings (which wont rust), small paper clips, staples, or magnetite sand. The advantage to using particles of iron, steel, or magnetite is that the particles form a detailed map of magnetic field lines. The map also gives a rough indication of magnetic field strength. Closely-spaced, dense lines occur where the field is strongest, while widely-separated, sparse lines show where it is weaker. The disadvantage of using iron filings is that theres no indication of magnetic field orientation. The easiest way to overcome this is to use a compass together with iron filings to map both orientation and direction. Try Magnetic Viewing Film Magnetic viewing film is a flexible plastic containing bubbles of fluid laced with tiny magnetic rods. The films appears darker or lighter depending on the orientation of the rods in a magnetic field. Magnetic viewing film works best mapping complex magnetic geometry, such as that produced by a flat refrigerator magnet. Natural Magnetic Field Lines The lines in the aurora follow Earths magnetic field lines. Oscar Bjarnason / Getty Images Magnetic field lines also appear in nature. During a total solar eclipse, the lines in the corona trace the Suns magnetic field. Back on Earth, the lines in an aurora indicate the path of the planets magnetic field. In both cases, the visible lines are glowing streams of charged particles. Magnetic Field Line Rules Using magnetic field lines to construct a map, some rules become apparent: Magnetic field lines never cross.Magnetic field lines are continuous. They form closed loops that continue all the way through a magnetic material.Magnetic field lines bunch together where the magnetic field is strongest. In other words, the density of field lines indicates magnetic field strength. If the field lines around a magnet are mapped, its strongest magnetic field is at either pole.Unless the magnetic field is mapped using a compass, the direction of the magnetic field may be unknown. By convention, direction is indicated by drawing arrowheads along magnetic field lines. In any magnetic field, the lines always flow from the north pole to the south pole. The names north and south are historical and may have no bearing on the geographical orientation of the magnetic field Source Newton, Henry Black and Harvey N.

No Topic - Assignment Example The company is doing its best to improve the infrastructure, but does not have enough information about its customers. The information about customers and their needs is necessary to gain new customers. The data should be gathered and properly analyzed to get to know whom to focus on. The company is not going to make any IT innovations, but they still need to use information technologies. IT are used by the competitors and it is essential to use them to keep the competitive advantage. The probable strategy to attract new customers is widely discussed by the Carnival’s managers. One of the most important things is to make the customers loyal. The one possible way is to use customers’ relationship management. CRM strategy has been already applied but due to the rather neglecting attitude towards information technologies, the strategy was not applied successfully. CRM strategy can help Carnival attract new customers and gather important data about them
