This means that the company has its own legal identity and its owners are not responsible for its debts, however they would lose the money that they put in at the beginning. Introduction: Tesco Company History Recant history Tesco is one of Britains leading food retailers and has 586 stores though out Great Britain. From 1992 Tesco has grown greatly and has increased its market share from 10. 4% to 15. 2%. This increse in customers has also given Tesco a large amount of profit. Tesco has 164,500 shareholders. Tescos profit is about 505 million pounds after the tax has been deducted; about 50%of this is then distributed to the shareholders as dividends. The rest roughly 250 million pounds is held back for investment in stores and improving services for the customers. The average shareholder holds between one and one thousand shares, but also banks, pension funds and building sercertys, hold a large amount of shares. Tescos share prices have risen since February 1997 when it was 349p to 586p on the 21st April 1998. The shares have peaked a high price of 603p. With this growth Tescos is now the largest super market chain. How Did Tesco actually start? Tesco was founded in 1924 by Sir Jack Cohen. He used his gratuity for his Army service in the World War to start selling groceries in Londons East End markets in 1919. The brand name Tesco first appeared on packets of tea in the 1920s. The name was based on the initials of T. E Stockwell, a partner in the firm of tea suppliers, and the first two letters of Cohen. The business grew and in 1947 Tesco Stores (Holdings) Ltd was floated on the stock exchange, with a share price of 25p. The price at the start of March 2001 the price raised to around 260p. When did the first Tesco self-service store open? Self-service supermarkets started in the USA in the 1930s during the depression. By selling a wider variety and larger volume of stock and employing fewer staff they cold offer lower prices to the public. Jack Cohen opened the first Tesco store in St Albans in 1948. When did Tesco open its first supermarket? In 1956 the first Tesco self-service supermarket was opened in a converted cinema in Maldon. By the early 1960s Tesco was a household name, as well as selling groceries, the stores sold fresh food, clothing and household goods. The Tesco store which opened in Leicester 1961 had 16,500 square feet of space and went into the Guinness Book of records as the largest store in Europe. By buying bulk and keeping costs down, Tesco should have been able to sell at very competitive prices to its customers. Until 1964 however suppliers were, by law, able to insist that retailers charged at a set price for their products (Retail Price Maintenance). The intention was to protect small shops against the lower prices that big retailers could offer their customers. How did Tesco deal with the law on Resale Price Maintenance? Tesco introduced trading stamps so that it could bring lower prices to customers. Customers collected stamps as they purchased their groceries and other items. When they had collected enough stamps to fill a book, they could exchange the book for cash or other gifts. Other retailers soon copied Tesco. Sir Jack was one of the leaders in pursuing parliament to abolish Resale Price Management in 1964. After this Tesco continued to offer trading stamps until 1977. How did the company grow in the 1960s? Apart from opening its new stores, Tesco bought existing chains of stores. In 1960it took over a chain of 212 stores in the north of England and added another 144 stores in 1964 and 1965. In 1968 the Victor Value chain became part of the company. When was the first superstore opened? Tesco introduced the concept of a superstore in 1967 when it opened a 90,000 square feet store in Westbury, Wiltshire. The term superstore was first actually used when Tesco opened its store in Crawley, West Sussex in 1968. How did Tesco change its image? By 1970 Tesco was a household name. The slogan Pile it high and sell it cheap was the title of Sir Jack Cohens autobiography. But as people were becoming better off, they were looking for more luxurious items as well as everyday household and food products. In the late 1970s the company decided to broaden its customer base and make its stores more attractive to a wider range of customers. Many of the older high street stores were closed and the company concentrated on developing bigger out-of-town superstores. Tesco finally stopped giving out trading stamps in 1977 at the same time as introducing a price cutting campaign under the banner Checkout at Tesco which proved to be a major success. How did Tesco maintain its growth in the 1980s? During the 1980s Tesco continued to build new superstores, opening its 100th in 1985. In 1987 it announced a i 500 million programme to build another 29 stores. By 1991, the popularity of Tesco Petrol filling stations at its superstores had made the company Britains biggest independent petrol retailer. In 1985 Tesco introduced its Healthy Eating initiative. Its own brand products carried nutritional advice and many were branded with the Healthy Eating symbol. By 1990 Tesco was a very different company from what it was 20 years before. The Tesco superstore offered customers free parking as well as cheap groceries and a pleasant shopping environment. In 1992, it opened the first Tesco Metro, a city centre store meeting the needs of workers, high street shoppers and the local community. This was followed by Tesco Express, combining a petrol filling station with a local convenience store to give local communities more choice in their shopping. Tesco broke new ground in food retailing by introducing, in 1995, the first customer loyalty card, which rewarded regular shoppers whilst helping the company discover more about its customers needs.

How Horror Movies Have Changed Film Studies Essay
How Horror Movies Have Changed Film Studies Essay Horror as a whole has been around for many years. Writers have unfolded tales of fear and fright in novels. Directors bring terror to life on the big screen. People have enjoyed being scared time and time again. But why do they like this? How has Horror become such a successful genre? Chilling stories were the humble beginnings of horror. In ancient times, the Greeks shared tales of hideous beasts with three heads, or powerful monsters that could turn a person to stone with a mere glance. Egyptian hieroglyphics told of a great beyond in which evil spirits, demons, and otherworldly beings dwelled. The Chinese worshiped and venerated their ghostly ancestors who would haunt them if they did otherwise. Every civilization had their share of myth and mystery, real or not. Horror novels originally come from a traditional Gothic writing style. The first mention of horror in literature comes from Horace Walpoles book The Castle of Otranto in 1764. Inspired by writers such as Ann Radcliffe and Matthew Gregory Lewis, Mary Shelley wrote the first rendition of Frankenstein in 1818. The nineteenth century in particular exploded with horrific literature writers, including Bram Stoker with the famous daunting tale of Dracula. Other well-known authors were Edgar Allen Poe, Wilkie Collins, and H. G. Wells. The first horror movies appeared on-screen in the 1920s. Credited as the first movie ever made, The Cabinet of Dr. Caligari was silent, dark and surreal, the specialty of the Grand Guignol Theater Company. The first monster movie, The Golem was released in 1920, which set the stage for the first vampire to appear on-screen in 1922. Though Nosferatu was the unauthorized German reproduction of Bram Stokers novel Dracula, it was nonetheless successful for the first film featuring these inhuman bloodsuckers. During the Depression of the thirties, people wanted something to keep them occupied and entertained. More people flocked to theaters and cinemas than ever before; 65% of the U.S. population saw films each week. Another reason for horrors sudden popularity was the invention of talkies, or movies with audio. Audiences now had soundtracks to keep them at the edge of their seats. Superb actors left guidelines for horror films for years to come. The thirties were one of the most successful eras in horror movie history. ((Karina Wilson, 2011)) The thirties were also explosions of the classic Universal monster movies. The franchise began with Dracula in 1931; although true to the original novel, the actor starring as Dracula never wore fangs! The same year, the original Frankenstein premiered. The next to appear was The Mummy in 1932. Finally in 1935 Werewolf of London came to the big screen; the actor, Henry Hull, also made alterations to his costume, using less fur and make-up that would otherwise cover his face entirely. The saga of these characters would continue until 1948, with Abbot and Costello Meet Frankenstein, which was the last nail in the coffin for the golden days of Universal monsters. ((Monsters in the Movies, 2011, pg. 1, 26, 27, 53, 54, 126)) In the forties, American citizens wanted anything to get their mind off of war. They wanted good, quality movies which the Horror genre was all too happy to make. Lon Chaney Jr. was now the man in the yak hair suit starring as his most famous role the Wolf Man. All of Americas fan favorites grouped together in numerous movies, such as House of Dracula and the many Abbot and Costello Humor Horrors. After the craze died down, zombies, gigantic apes and ghosts took their place. ((Karina Wilson, 2011)) Atomic mutations were the craze of the fifties. Radiation exposure, mutations and gigantic beasts could be seen in just about every movie created during this time. Titles such as Godzilla, Them, The Incredible Shrinking Man, and Attack of the Crab Monsters appeared in every drive-in and were huge hits. ((Monsters in the Movies, 2011, pg. 202-207)) Then came what is now called the worst film ever made. Plan 9 from Outer Space was a horrid mash-up of mutants, zombie slaves, and alien vampire overlords. Though this did not mar the fifties in horror history, it is still a prime example of how not to make a movie. ((Karina Wilson, 2011)) In 1959 Jack the Ripper began an era for serial killers and slasher horror. The most well-known horror film director Alfred Hitchcock makes a name for himself with his film Psycho during this time. Hundreds of directors have attempted to copy this brilliantly terrifying film, but none can match it. Also made by Hitchcock in 1963 was The Birds. During the same year, the first splatter film Blood Feast was released. This was the first of many to have seemingly endless gore for no apparent reason. All of these films have one thing in common: They were created on low budgets. This was common in most sixties films, but nearly all of them were huge hits. ((Monsters in the Movies, 2011, pg. 290, 293)) ((Karina Wilson, 2011)) Seventies horror had audiences with nightmares for weeks. From Piranha to The Legacy, there was almost no humor in these movies. The Exorcist in 1973 set a gold standard in Horror and was voted the scariest movie of all time in October of 1999. People are said to have passed out in audiences watching this film. Not only were there possessed demonic children, but cannibals as well. The Texas Chainsaw Massacre made in 1974 barely showed the audience any gore, but mixed with a chilling soundtrack and terrifying characters, the viewers imagination filled in the gaps. Psycho-killers were re-defined entirely because of the seventies. The eighties were as terrifying as the decade before, with chainsaws, cannibals, and even more deranged predators prowling the night. The horror franchise skyrocketed with Friday the 13th, having eleven sequels to this brutal splatter film. A Nightmare on Elm Street wasnt much better, as audiences feigned sleep entirely because Freddy might get them. However, as proven by popularity, people couldnt get enough of horror. ((Monsters in the Movies, 2011, pg. 226)) The beginning of the nineties was when horror directors truly saw how de-sensitized the common person was. Those horror films of the past merely made them laugh. They needed something new, something that hit closer to home. The serial killer is a big part of nineties horror, such as in Se7en and Silence of the Lambs. Also coming into play were space monsters, aliens bent on destroying or taking over and then destroying all mankind. Unlike the fifties, these aliens looked real, had real motives, and were genuinely scary. ((Monsters in the Movies, 2011, pg. 258, 259)) ((Karina Wilson, 2011)) In 2000, the sequel to Final Destination was produced, marking the beginning of a chain of movies that hit the modern American harder than Saw ever did. These were events although typically never to happen on a normal day that could in fact happen at any given time. ((www.horrorfilmhistory.com/index.php?pageID=2000s )) Nowhere seemed like a safe place anymore, especially when viruses and zombie apocalypses were taken into account; 28 Days Later is a prime example of this. An on-going series that also goes along with this idea is The Walking Dead, first aired in 2010. ((Monsters in the Movies, 2011, pg. 227, 307)) Old horror films were scary in their time because the general public had never been exposed to movies that targeted fear before. They are not as impacting to us today because they were made to frighten audiences in that time period, who were not as de-sensitized as the modern human being. What a person was afraid of in the 1920s is certainly not the same as what we fear. ((Richard Sine, WebMD)) Newer horror movies are made for those who enjoy being scared. If a person intends to see the newest slasher film at a theater, theyve obviously been exposed to those elements before. Directors of these films assume that their audiences like the thrill of being terrified. A killing spree in a movie might seem harsh, but you may get little to no response from a seasoned audience. ((Richard Sine, WebMD)) Over the years the definition of horror may have been altered and re-defined, but as always the general public is satisfied. As long as there is fear, there is a director willing to put that fear into the next box office hit. Horror films have been cherished for years, and will continue on for decades to come. Who knows what the newest advertisement or feature presentation will bring? à ¢Ã¢â ¬Ãâ à ¢Ã¢â ¬Ãâ

Reticence :: essays research papers
Reticence THIS MORNING there was a dead cat in the harbor, a black cat that was floating on the surface of the water. It was straight and stiff and was drifting slowly along the side of a boat. From its mouth dangled a decomposed fish head with a piece of broken line about two inches long coming out of it. At the time I had simply imagined that this fish head was what remained of the bait from a discarded fishing line. The cat must have leaned into the water to catch the fish and, as he grabbed it, the hook caught in his mouth and he lost his balance and fell. The water of the harbor was very dark where I was standing, but from time to time I suspected there was a procession of fish, mullets and wrasse, passing silently below my eyes, while on the bottom, among the pebbles and algae, thousands of wriggling fry worked over the gutted remains of a decomposing eel. Before setting off again, I lingered a moment longer on the pier staring at the dead cat still drifting in the harbor in a very slow back and forth movement, first to the left, then to the right, following the imperceptible ebb and flow of the current at the surface of the water. I had arrived in Sasuelo at the end of October. It was already autumn and the tourist season was coming to an end. A taxi dropped me off one morning, bag and baggage, on the village square. The driver helped me undo my son's stroller from the roof-rack of the car, an old 504 diesel that he left running and that continued to hum slowly in place. Then he pointed in the direction of the only hotel in the area, that I was familiar with since I had already stayed there. I left my bags near a bench and set off in the direction of the hotel with my son who was installed in his stroller in front of me and paying no attention to anything around him, absorbed as he was in the contemplation of a toy seal that he turned over and over in his hands examining all its seams and releasing for the occasion an imperturbable burp as naturally as a prince. At the entrance of the hotel flowers lined a little flight of steps at the top of which opened double French doors, and I took the stroller in my arms to climb the steps.

The Federal Reserve System :: essays research papers
The Federal Reserve System was founded by Congress in 1913, it began to operate in Nov., 1914. Its setup, although somewhat altered since its establishment, particularly by the Banking Act of 1935, has remained substantially the same. Structure The Federal Reserve Act created 12 regional Federal Reserve banks, supervised by a Federal Reserve Board. Each reserve bank is the central bank for its district. The boundary lines of the districts were drawn in accordance with broad geographic patterns of business, and the banks were placed in Boston, New York City, Philadelphia, Cleveland, Richmond, Atlanta, Chicago, St. Louis, Minneapolis, Kansas City, Dallas, and San Francisco. In addition some of the regional banks have one or more branch banks attached to them. All national banks must belong to the system, and state banks may if they meet certain requirements. Member banks hold the bulk of the deposits of all commercial banks in the country. Each member bank is required to own stock in the Federal Reserve bank of its district and must maintain legal reserves on deposit with the district reserve bank. The required reserves are proportionate to the member bankââ¬â¢s own deposits, the proportion varying according to the location of the member bank and the character of its deposits. Each reserve bank is managed by a board of nine directors (three appointed by the Federal Reserve Board, six by the local member banks). The Federal Reserve Systemââ¬â¢s Board of Governors designates one of the federally appointed directors as chairman and Federal Reserve agent; it is the chairmanââ¬â¢s duty to report to the Board. The board of directors appoints the bankââ¬â¢s president and other officers and employees. The operations of the Federal Reserve banks, although not conducted primarily for profit, yield an income that is ordinarily sufficient to cover expenses, to pay a 6% cumulative dividend annually on the stock held by member banks, to make additions to surplus, and to provide the U.S. Treasury with over $1 billion a year in revenue. The Board of Governors of the Federal Reserve Systemââ¬âthe national supervisory agencyââ¬âis composed of seven members appointed for 14-year terms by the President. Its offices are in Washington, D.C. The Federal Open Market Committee, created later (1923) than the systemââ¬â¢s other divisions, comprises the seven members of the Board of Governors and five representatives of the Federal Reserve banks; it directs the purchases and sales by the reserve banks of federal government securities and other obligations in the open market.

Who Tamed Fire First? Essay -- Exploratory Essays Research Papers
Who Tamed Fire First? The farther back in time we explore, the more room there seems to be for discrepancy among various theories regarding the history of the earth. One of the many disputed aspects of history concerns the nature of the relationship between humans and the environment. This paper will focus on the debate of the origin of first tamed fire. Was it Homo erectus or Homo sapiens? The widely accepted big bang theory of evolution "paints Homo erectus as no more than a smart ape," (McCrone, New Scientist, May 20, 2000, 31) with a, "15-minute culture," (McCrone, 34) incapable of manipulating his surrounding environment. Though even if we were to believe he was physically capable of accomplishing this act, McCrone explains, "controlling fire simply seemed too intellectually sophisticated a feat for this creature," who were, "primitive toolmakers, and showed no signs of symbolic thinking over the next million or more years of their existence," (McCrone, 31). Under this theory, any remains of fires from his time are written off as bush fires, lightning strikes, and other such naturally induced occurrences. It is not until Homo sapiens comes along that humans are considered to have begun to "master" their environment. A recent, more scientifically based analysis of ancient Chinese fires supports this same stance that Homo erectus was not the first to tame fire. The geological analysis took place at the Zhoukoudian site in China, where an opposing theory marks the first controlled fire at 500,000 years ago by Homo erectus' hands, (Wuethrich, Science Magazine, July 10, 1998). Though they confirmed recovering burnt bones from the site, there was no solid evidence to suggest the controlled use of fire, such as hearths,... ...order in our world. It gives us a past, present and future. Time also offers us a sense of perspective, so that we can make insights and connections, decide what is true and what is false, what is valuable and what is inconsequential. In this regard, the debate over the time and origin of the first tamed fire is an effective illustration of the ways in which time affects our perception of human kind and its relationship with the environment. Which theory of origin we ultimately choose to believe is particularly significant in that it gives insight into the way in which we view ourselves in relation to our past.

Burke-Litwin: Understanding Drivers for Change Essay
There are many reasons that change occurs in organisations. Building on the Burke-Litwin model of organisational change and performance, this article will help you identify different drivers of change and consider the implications for you as a change manager. The Model The Burke-Litwin model[1] shows the various drivers of change and ranks them in terms of importance. The model is expressed diagrammatically, with the most important factors featuring at the top. The lower layers become gradually less important. The model argues that all of the factors are integrated (to greater or lesser degrees). Therefore, a change in one will eventually affect all other factors. The Burke-Litwin model Burke-Litwin believe environmental factors to be the most important driver for change. Indeed, most change can be traced back to external drivers for change. Important elements of organisational success, such as mission and strategy, leadership and organisational culture, are often impacted by changes that originate outside the organisation. It is your job to understand these external changes and identify the implications for you and your team. Identifying and Dealing with Drivers for Change 1. External Environment This includes such factors as markets, legislation, competition and the economy. All of these will have consequences for organisations, and, as a change manager, it is vital that youà continually scan the environment for issues that will affect you and your team. For example, in the world of accountancy, International Accounting Standards and International Financial Reporting Standards will have a significant impact on the way companies manage their accounts and report their results. In the public sector, legislative changes across health, local government and other services have a direct impact on the work organisations are required to carry out. 2. Mission and Strategy An organisationââ¬â¢s mission articulates its reason for existing. It is the foundation upon which all activity should be built. The strategy then sets out, in broad terms, how the organisation will go about achieving its mission. Very often, the strategy will be developed in light of environmental change, and will have a significant impact on the work you do. As a change manager, you need to understand change in strategy and be able to communicate the implications to your staff. 3. Leadership This considers the attitudes and behaviour of senior colleagues and how these behaviours are perceived by the organisation as a whole. The way in which change is implemented and accepted through the organisation will be largely influenced by the top team. Does your team believe that senior colleagues are committed to change, or is it just another initiative that will disappear in six monthââ¬â¢s time? 4. Organisation Culture Organisation culture can be described as ââ¬Å"the way we do things around hereâ⬠. It considers the beliefs, behaviours, values and conventions that prevail in an organisation. Culture change does not happen overnight. It evolves over time as a result of many other changes in the organisation. As a manager, you should keep in mind the desired state for the organisation, in terms of how you expect people to behave (and not to behave), and what your organisation values as important. You need to ensure that your behaviour fits with these expectations at all times, and that you ââ¬Ëwalk the walkââ¬â¢. 5. Structure Very often, changes in strategy can lead to changes in the way the organisation is structured. This can impact on relationships, responsibilities and ways of working. Your job is to assess the impact of the structural change and ensure your team understands why it is required, and what it means for them. 6. Work Unit Climate This considers employeesââ¬â¢ perception of their immediate colleagues and working environment. Our immediate working environment is often what shapes our view of the organisation as a whole, and influences the extent to which we feel satisfied in our jobs. Changes to the immediate working environment need to be managed sensitively, as they are likely to invoke a range of emotional and political responses from staff. This is particularly the case where change involves moving location, a change in personnel, or a change in terms of conditions of service, such as working hours. 7. Task Requirements and Individual Skills/Abilities Change at a higher level in the organisation will often require changes in the work carried out and the skills available in the team. As the change manager you need to assess whether: all the right skills are in place; if they can be developed; or, if you need to bring them in from outside the team. 8. Individual Needs and Values Changes to team membership can mean a change in the team dynamic. In a perfect world, we would be able to recruit the exact fit for our teams, in terms of personal style, abilities and skills mix. However, in reality it is not always possible, and it is your job to identify any risks in this areas and mitigate them as best you can. 9. Employee Motivation Considers the significance of individual and organisational goals. Motivation is key to effective change. The real challenge is to maintain motivation throughout a change project, particularly when change is often not well-received by those affected.

Origin of life Essay
In the summary given, theory of life is said to have risen from the primitive earthââ¬â¢s atmosphere. The atmosphere of the early earth is said to have many carbon dioxides but no oxygen. These carbon dioxides will act as reactants in order to create much more complex organic substances such as proteins, carbohydrates lipids, phospholipids, and nucleotides. The said substances are well known as the building blocks of life. This is the evidence that supports their claim that life originated from the gases present in the early earthââ¬â¢s atmosphere. Also to support their claims, an experiment during the early 1950ââ¬â¢s would confirm that it is true that simple carbon based compounds can naturally be created under the environment of the primitive earth. In other readings, the early life is said to have also talks about the building blocks of life. The Panspermia theory proposed that these building blocks of life would have originated outside of the earth. These building blocks or the ââ¬Ëseed of lifeââ¬â¢ might be scattered around the galaxy or even the universe. Also the same as the summary in piecing it together, the panspermia theory suggests that whenever conditions are met, the building blocks of life will grow and develop. The only downfall of the theory is that, since the building blocks of life came from outside the earth, then there is a great possibility that other life may form from outside of the earth. Evidence of this theory is that, a certain bacteria were discovered in the earthââ¬â¢s upper atmosphere. Whatââ¬â¢s interesting with the discovery is that the bacteria were similar to the bacteria found in the earth. The bacteria might brought by the space crafts that left the earth. But still, there is a probability that the bacteria would have evolved from outside of the earth. Unfortunately, this theory is lacking in evidence. Some scientists are still on the verge of research in order to prove that their claims were right (Backman, 2007). The summary has a basis about its claims of the origin of life. But problems arise. The origin of the earth is still not established very well. It is said in the summary that substances from the early earth will evolve but the existence of the early earth is not yet been proved. Both the theories lack evidence to support claims of the origin of life.
