Definition of Marketing Essay Example | Topics and Well Written Essays - 500 words
Definition of Marketing - Essay Example Marketing is more concerned with developing demand for a product and satisfying customersââ¬â¢ needs and not necessarily for customers to pay for the goods. Customer relationship is a very important and efficient approach that helps in creating and maintaining the good relationship with the customers. Customer relation brings about a strong bond through personal and emotional linkage and the organization can know the actual needs of the customer (Oly, 2007). Loyal customers are quite important as they have a big likelihood of telling more people about your business through the word of mouth. External customers always like to feel needed by the business operators and communication with them is very important. A satisfied customer will always be happy with the business and remain forever, which will help in enhancing the growth of the business. Dealing with customers efficiently increases their satisfaction increasing the chance of making more sales and high profits. A business strategy involves the tactics and methods business persons use to manage their businesses and organizations. Having an effective business strategy helps in retaining the customers especially if there is a program for following up the customers to find out whether the items they bought are in good condition (Oly, 2007). A good organizational and business strategy ensures that resources are used efficiently to avoid wastage. Some of the resources in a business organization are personnel customers, reputation in the market, patents, warehouses, and manufacturing processes. Business strategies should utilize the companys resources to ensure that the company does not lose its customers and has a big market share. Good company strategies enhance its expansion and growth through promotion of vigorous marketing research. Research helps in venturing into new areas to increase its production and promote growth. The other importance of strategy is giving directions and action plans, prioritization and

The debt ceiling Term Paper Example | Topics and Well Written Essays - 250 words
The debt ceiling - Term Paper Example This happened since the government did not want a repeat of 2001 fiscal crisis, which was because of the Congress refusing to raise the debt ceiling. However, raising the debt ceiling has driven the national debt to wanting levels; $14.3 trillions. In my opinion the debt ceiling should be raise, but as a short-term measure. This is because failure to raise the ceiling would have consequences. The first consequence is that the government may be unable to pay its workforce their salaries. This may lead to unrest in the country. Secondly, the government may default on what it owes other creditors, for examples, holders of government securities. These are monies in terms of bondsââ¬â¢ principal and interest. This would result to the US government having a bad credit rating. Government securitiesââ¬â¢ risk would go up causing the rate of interest attached to them going up. As a result, the cost of capital in the entire economy would go up thus increasing the cost of doing business. This in turn would lead to economic growth slowing down (Allen, 2012). Thirdly, foreign investors might lose faith to the US government thus refusing to lend to it. They may also sell their US governmentââ¬â¢s securities. This, in turn, may lead to the dollar losing value against the world currencies. All these may compound the situation and return the economy back to recession (Allen, 2012). Additionally, other conditions should accompany the raising of the debt ceiling. These should be long-term measures. First, the government should cut spending on unproductive activities such as wars and defense. These are some of the government expenses, which do not add value to the economy. Cutting spending on these activities would reduce the budget deficit, which would enable the government to lower the debt ceiling in future. Finally, the government should increase taxes on corporate and the rich to reasonable rates that should not hurt the economy. This too would help in reducing the budget

Goetheââ¬â¢s Faust Essay Example for Free
Goetheââ¬â¢s Faust Essay Scene vii of Faust ii act v takes place in a steep, rocky side of an unspecified mountain. The scene is dominated by female characters and takes place on earth. It starts with a chorus of nature spirits, in which the nature is describes the mutually interdependent processes taking place. The idyllic conditions described by the chorus of nature are the celebration of processes like plant and animal life, earth and water. Then enter the four anchorite fathers, who seem to represent progressively increasing degrees of spiritual attainment. First there is Pater Ecstaticus who is hovering up and down in the air. Then there is Pater Profundus who apparently lives in the depth of the earth. He marvels at the creative processes of nature and describes lightning, trees which strive to reach heaven and water flowing from heaven to earth. His heart is however is not at peace and he asks for a divine illumination from the Lord ââ¬Å"Oh, God! Calm my thoughts, pacify us/ And bring light to my needy heart! â⬠The third father is Pater Seraphicus. He lives in the middle regions, (probably between the air and earth). He invites the spirits of young boys who died at birth and had not thus experienced earthly life to come and experience the world through his body. Then a group of angels pass by carrying the soul of Faust and relate why they rescued Faustââ¬â¢s soul. We learn that Faust soul was saved because he struggled so much in developing his projects (ââ¬Å"Whoever strives, in his endeavor, we can rescue from the devil. â⬠). In this instance we are also told of the other reason why Faustââ¬â¢s soul was saved which is that Gretchen was interceding for him to Mother of God. The Younger Angels say of how they distracted the Mephistopheles by using roses of holy love. The More Perfect Angels also say that even though the heart of Faust has ââ¬Å"escaped the flamesâ⬠it is still impure and that the bond between the soul and body is left for ââ¬Å"Eternal Loveâ⬠to unwind. The angels then take Faustââ¬â¢s soul to the blessed boys above who ââ¬Å"Joyfully receive Him as a chrysalisâ⬠after all the ââ¬Ëthreads that surround himââ¬â¢ disappear since ââ¬Ëdivine love has found him. ââ¬â¢ Then we meet the fourth anchorite father, Doctor Marianus who resides in ââ¬Ëthe purest cellââ¬â¢. When he sees ââ¬Å"womanly shapesâ⬠floating around he starts praising Mater Gloriosa and together with the choir of penitent women, Magna Peccatrix, (the woman who anointed Jesusââ¬â¢ feet), the Samaritan woman who met Christ at the well and Mary of Egypt together plead to Mater Gloriosa not to begrudge the true soul of Gretchen. They plead that she transgressed without knowledge of her fall. The Gretchen herself goes to Mater Gloriosa and pleads on behalf of Faust asking Mater Gloriosa to allow her, Gretchen, to teach him the new ways there since he is still blinded by the bright light. She says that Faust is a completely new person having ââ¬Å"thrown off every bond/ Of his old earthbound integument,â⬠The scene ends when Mater Gloriosa accepts Faustââ¬â¢s soul and beckons Gretchen and all the others to follow her into the higher sphere. This scene takes place by the Aegean Sea where the Sirens are addressing the Moon. The Nereids and Tritons are also swimming around and even swim to the Greek mythological island of Samothrace, ââ¬Ëthe domain of the mighty Cabiriââ¬â¢ in an effort to show that they are more than fish. Meanwhile, Thales and Homunculus have gone to visit the sea god, Nereus for advice on how Homunculus can be reborn completely. Thale tells Homunculus that though Nereus is stubborn and a grumbler, people respect him because of his wisdom. They then meet Nereus, who is angry and wants to send them away, he tells them of how men can never heed advice and tells them of how Paris laughed at him when he told him of the future he saw, he also tell them of how he warned Ulysses of ââ¬ËCyclopsââ¬â¢ horrors and of Circes wilesââ¬â¢ but the advice brought Ulysses no gain. He tells them finally to go to Proteus, the shape changer since he is waiting for Dorides and Galatea. Nereids and Triton arrive then carrying Cabiri in a turtle-shell and Thales and Homunculus watch the procession. Proteus, who is hovering near is so attracted by the light that that homunculus emits. He draws near and Thales asks for advice on Homunculusââ¬â¢ behalf. Proteus suggests that homunculus can repeat the human birth process by starting in the sea and then develop to a full being. They then all (Thales, Proteus and Homunculus) leave together to go and watch the sea festival. In the procession, the Telchines, the nine dog-headed Children of the Sea, pass by and boast that they were the first to shape gods in the image of man. Galatea finally arrives and Nereus, the Sirens and Thales comment on the doves of Paphos which accompany Galatea. Galatea comes closer to her father. And in the process Homunculus drawn near and smashes the glass that holds him at the feet of Galatea and all marvels as the light of Homunculus mixes with the waves in a symbolic marriage with the sea. Analysis of the acts In both these two acts there is a strong reference to the female presence. The female presence in act v is represented by Mater Glorioso, Gretchen, Choir of Female Penitents, Magna Peccatrix, The Woman of Samaria, Mary of Egypt and the female forms that hover in the sky which Dr. Marianus. The strong women influence in this act, as in the rest of the drama, shows the empathetic face of women. The three repentant women plead for Gretchen while Gretchen pleads for Faust. The women are a strong symbolism to life givers. Mater Glorioso gives Faust soul another life by uttering few words. In this act we also know that the soul Faust is received by the young boys in a ââ¬Ëpupalââ¬â¢ stage. This is so like Homunculus, who is a half being and only survives in a bottle. The rebirth of Homunculus takes place when he joins with the Galatea in a sea wedding. This is what completes Homunculus. Faust soul is also completed by the love of Gretchen. It is Gretchenââ¬â¢s love that finds him and is to lead him in the new place since ââ¬ËThe new light still blinds him. ââ¬â¢ In act ii, there is also an overwhelming female presence. The sirens, Nereids and Tritons, Galatea, Dorides are all representative of female personalities. Generally this act is one in which the three, Homunculus, Faust and Mephistopheles are on a search of what completes them, which in the three cases happen to be the female personality. References Wolfgang, Johann von Goethe. Faust. Berlin: Bernhard Tauchnitz, 1867.

Claude and the Classical Dream :: essays papers
Claude and the Classical Dream In Kathleen Nicholson's book, Turner's Classical Landscapes, is an interpretation of Turner's concepts and ability of landscape painting in contrast to Claude. In particular, chapter six, Nicholson discusses Turner's artistic career and how it models Claudean classical landscape. Nicholson conveys her opinion on how Turner re-created Claude's a realm to maintain a balance between homage and revision, between landscape as a tradition and landscape as a modern form of expression. Kathleen Nicholson, in this chapter, takes the reader through many aspects of Turner's re-creation of Claude's classical landscape into his own modern form. Turner understood Claude's qualities as an artist. He clearly knew the extent to which Claude's art came from, with extensive study of nature, part by part, and a realization that informed his own process of idealization. Nicholson states, " Allow he showed proper respect to Poussin, his heart went out to Claude (222)" because Turner saw Claude's work as the realm of the classical landscape. Many other artists, such as Constable, looked at Claude's works for inspiration in aspects ranging from the design of rivers to the finish. Other artists continuously copied Claude's landscape paintings as a basis for representation of their own landscape. Turner instilled Claude's work into two compositional formats, a seaport and an inland setting, which he would personalize and update while at the same time leaving no doubt about their source. However, at the beginning of Turner's career, he believed that Claude's work was beyond the power of imitation. At first, he followed Poussin's order and rationality in his 1800 and 1802 Plague pictures. Poussin may have seemed more comprehensible to Turner before being exposed to more of Claude's paintings. After a visit to the Lourve, Turner's paintings appeared more and more like Claude's, especially in the Thames River paintings, where Turner used an air of eternal beauty to counterbalance the changeable effects of English weather. Nicholson finds Turner's sketchbook as the example of how Turner's idealization derives from the kind of exchange between the natural and the imaginary. She states,"His projection of a harmoniously arranged natural environment never subjects to the ravages of time imparted an elegance and breadth to his observation of the real world (223)". Nicholson finds his sketchbook to be a journey that embarks through imagination and the sensual. The first pages of the book depict a little ship ready for departure.

Adolf Hitler Conspiracies Essay
Did Adolph Hitler really commit suicide on April 30, 1945? Hitler is believed to have poisoned and shot himself along with his newlywed wife, Eva Braun, on April 30, 1945 while in an underground bunker in Berlin. Then, Hitler and his wifeââ¬â¢s body were burned outside the bunker. However, many questioned whether this really happened so they have conspiracies on Hitlerââ¬â¢s death. Three main conspiracies that really challenge Hitlerââ¬â¢s suicide are that the skull found in the bunker did not belong to him, no shots were heard by bystanders in the bunker, and he had an imposter kill himself. So Hitlerââ¬â¢s death may have been a hoax due to the evidence from several sources, showing that Hitler may have never committed suicide in that bunker and he had escaped from Germany. The skull that was believed to be Hitlerââ¬â¢s, which was taken by the Russian army and preserved by Soviet intelligence, is now proven by DNA analysis to be of a woman under 40 years old. The bodies of Hitler and Eva Braun, Hitlerââ¬â¢s wife, after they died, were said to have been wrapped in blankets and carried to the ââ¬Å"garden outside the bunker, placed in a bomb crater, doused with petrol and set ablazeâ⬠(ââ¬Å"Fresh Doubts over Hitlerââ¬â¢s Deathâ⬠¦Ã¢â¬ 3). However, Stalin, who was suspicious about Hitlerââ¬â¢s fate, had the Russian forensics team dig up Hitlerââ¬â¢s body, but a part of the skull was missing. The Russians eventually found the other fragment to make ensure Hitlerââ¬â¢s death. However, American researchers were finally able to examine the skull fragment after it had been under strict possession of the Soviets. The researchers found out the skull fragment belonged to a women under 40 years old because in their DNA analysis of the skull they found that ââ¬Å"the bone seemed very thin; male bone tends to be more robust. Also the sutures where the skull plates come together seemed to correspond to someone under 40â⬠(ââ¬Å"Fresh Doubts over Hitlerââ¬â¢s Deathâ⬠¦Ã¢â¬ 2). But Hitler was 56 in April 1945 so the skull could not have belonged to him. Braun was believed to have been killed as well so the skull fragment could belong to her and she was 33 years old when she died. Overall, Hitlerââ¬â¢s suicide has been greatly challenged by this astonishing discovery about the skull fragment believed to be Hitlerââ¬â¢s. Skull Fragment Believed to Belong to a Woman, not Hitler (ââ¬Å"Fresh Doubts over Hitlerââ¬â¢s Death..â⬠1) Nobody actually saw Hitler shoot himself on April 30, 1945. The guards near the bunker claimed they heard nothing, but many of them withdrew their claims because they said Allied interrogators pressured them into saying that. Also some people who claimed to have heard the shot werenââ¬â¢t even there. Otto Gunsche, Hitlerââ¬â¢s SS adjutant, claimed to have been in the conference room with Nazi Party Secretary Martin Bormann and Propagnda Minister Josef Gobbels when he heard the shot, and then he claimed they ââ¬Å"rushed to the anteroom with Gobbels in leadâ⬠(ââ¬Å"Adolf Hitler Death and Survival Mythsâ⬠2). However, Rattenhuber, commander of Hitlerââ¬â¢s SS guards claimed that Gunsche was already in the anteroom when he arrived. So Gunsche couldââ¬â¢ve helped Hitler escape from the bunker without anyone else knowing. Also Hitlerââ¬â¢s chauffeur Erich Kempka and former Reich Youth leader Artur Axmann claimed that they saw a body being carried out of the bunker ââ¬Å"which was wrapped in blanket and was dressed in Hitlerââ¬â¢s trousers, shoes and socksâ⬠, but they didnââ¬â¢t get a valid identification of Hitler. If no one actually physically saw or heard Hitler shoot himself, how do they know he really shot himself ? Layout of Hitlerââ¬â¢s Bunker (ââ¬Å"Navona Numismatics..â⬠1) Most of the conspiracies on Hitlerââ¬â¢s death have to do with him having a double. Around 2 P.M on April 30, 1945, Hitler had a strange conversation with his personal pilot, Hans Baur. Baur begged Hitler to escape to Argentina, to Japan, or to an Arab country, but Hitler responded ââ¬Å"I am ending my earthly stay.â⬠(ââ¬Å"Adolf Hitler Death and Survival Mythsâ⬠2). Notice Hitler said ââ¬Å"earthly stayâ⬠instead of ââ¬Å"lifeâ⬠which implies that Hitler was no longer going to be on Earth or that he was planning some sort of escape. Between 2:30 P.M and 3 P.M, Gunsche made a phone call to Kempka and asked him for two hundred liters of gasoline to be at the entrance of the Fuhrerbunker. Notice that Hitler did not make the phone. Could this have meant Hitler had already escaped and his double filled in his place? The Russianââ¬â¢s photo of Hitlerââ¬â¢s corpse was indeed not Hitler, it was his double, or Doppelganger, Gustav Weber , who was executed with a gunshot to the forehead, and itââ¬â¢s obvious that itââ¬â¢s not Hitler because Hitler shot himself in the temple. Russian photo of ââ¬Å"Hitler Corpseâ⬠(ââ¬Å"Adolf Hitler Death and Survival Mythsâ⬠4). Adolf Hitlerââ¬â¢s suicide on April 30, 1945 has been challenged by these three conspiracies: the skull found in the bunker did not belong to him, no shots were heard by bystanders in the bunker, and he had an imposter kill himself. In the first conspiracy, researchers were able to examine the skull that was believed to belong to Hitler, but after a DNA analysis of the skull, they found out that the skull belonged to a female under the age of 40 due to its thickness and structure. Then in the second conspiracy, Hitlerââ¬â¢s bodygurads and comrades who were in the bunker with him claim to have never saw or heard the gunshot from Hitlerââ¬â¢s suicide. In the final conspiracy, Hitler was believed to have a double take his place and commit suicide while he escaped out of the bunker. All three of the conspiracies have valid and credible evidence so if they are true, then Adolf Hitler may have indeed faked his death and escaped from Germany on April 30, 1945.

Analysis Of George Elton Mayo And His Work Essay - 5478 Words
Early insights around employee engagement originated with George Elton Mayo and his work at Hawthorne Works (a General Electric Company) in the 1920s. In studying human behavior, Mayoââ¬â¢s research challenged Taylorââ¬â¢s principles of scientific management by providing alternative motivation theories outside of self interest (Mayo, 1933). This opened the door for additional research on employee motivation with future work by Argyris and Likert continuing to drive understandings of the relationship between environment and worker productivity. While the book First Break All the Rules (Buckingham Coffman, 1999), helped popularize the concept of employee engagement, the first real mention of employee engagement appeared in a 1990 Academy of Management Journal article by William Kahn. Basing his initial work on Goffman, Kahn looked to further develop the concept around varying individual role attachment by extending the concept to fit organizational life (Kahn, 1990). Specifically, Kahn (1990), utilized an ethnographic, grounded theory method to better understand how experiences with various work variables including manager satisfaction, role clarity and availability of resources influenced an individualââ¬â¢s experience and involvement with work tasks. Kahn looked to build upon prior work by Hackman Oldham (1980) and Alderfer (1972) to enhance or undermine the individualââ¬â¢s motivation and sense of meaning at work (Kahn, 1990). The research premise was that 1) individualShow MoreRelatedHistory of Management Th ought - Elton Mayo1620 Words à |à 7 PagesINTRODUCTION This essay covers the life and key contributions of Elton Mayo, a renowned figure in management science, and how his theories have made a significant impact in management today.
