MBA Industry and Porter’s Five Forces Essay

MBA Industry: The MBA school industry includes universities and colleges that offer academic courses and grant graduate degrees. The general requirement for admission is a bachelor’s degree and GMAT ® scores. Some schools and programs also require prior employment experience. Instruction is typically provided on physical campuses, although online education and other unconventional approaches are gaining popularity. For purposes of this paper, for-profit institutions or community colleges are not included in the industry definition. The major forces that affect MBA market are: competition between public and private business schools, buyers of business education including both students and employers, faculty as the key suppliers to the industry, and substitutes in the forms of alternative means of delivering graduate business education. Porter suggests that evaluation of these forces will provide insights into the prospects for long-range profitability1. Competition: The MBA m arket in the United States is an unregulated industry that allows schools to develop their own distinctive styles and personalities, and to define their own missions5. B-Schools consider it their mission to educate and research, but face intense pressure of managing faculty issues, finding new funding sources and distinguishing themselves from competitors9, highlighting the most prominent areas within this category: cost, revenues, and reputation. Reputation is differentiated by rankings and accreditations, specializations and regional focus and flexibility10. Rankings drive how students, faculty, and employers perceive the MBA program. In turn, how students, faculty, and employers perceive the MBA program drives rankings, resulting in developing a brand name for universities, leading schools to expend vast resources in pursuit of being highly ranked or even ranked at all8. The significant costs associated with business education have left room for competitive entry by low cost providers. B-Schools now face the reality that they must compete with the low-cost providers who can turn a profit because they are not burdened with the high fixed costs of the â€Å"bricks and mortar† university4. As tuition alone will not cover the costs of running an MBA program, funding is usually sourced from donations from alumni. Most successful schools are usually ones backed by alumni that are willing and able to give back to their alma  maters. Suppliers: The most important suppliers to the MBA industry are the business school faculty who fill the teaching, research, and administrative roles with any MBA program. There is an increasing demand for qualified business faculty, while simultaneously there is a stagnating or decreasing supply of such faculty. As the pool of high quality, freshly minted Ph.D.’s is diminishing; competition for associate and assistant professors is increasing. Institutions that can afford to bid are becoming more aggressive in recruiting faculty from other schools, inflating salaries beyond what some can afford10. Rising salaries for new hires has encouraged experienced faculty to move to different institutions to receive pay raises of their own, and thus the market continues to stay extremely competitive. Buyers: The buyers of graduate management education are either the students, employers, or both. With respect to the power of student as buyers, both the MBA programs and the students possess some leverage. There is obviously significant demand for the MBA degree from students because they believe that it will enable them to receive greater opportunities in their career, receive a higher salary, or launch them into a new career7. Employer preferences have a significant effect on market for MBAs. The employer’s demand for MBAs dictates the job availability and salary range, which is proportional to demand for MBAs. Employers are always seeking the best value to raise their company’s performance by enhancing employees’ abilities. What employers define as â€Å"benefit,† however, can range from training, which raises employee efficiency to higher-level education, which emphasizes critical thinking and complex problem solving skills. Substitutes: Most participants do not enter to challenge industry leaders but to offer tailored programs that appeal to sub -sets of their prospective students. Top-ranked business schools have little need to worry about substitutes. Consumer demand for the â€Å"Top brand MBA† will always outpace the supply. The same threat to mid and lower tier schools, however, is real. The online and distance learning schools target the same students that would otherwise attend these schools forcing the lower tiered schools to diversify their offerings6. Barriers to Entry: The main barriers to entry for new entrants in MBA industry are infrastructure costs, attracting and retaining good faculty, and gaining accreditation for courses. Schools must have a solid reputation to charge more tuition to attract students and afford good professors that produce strong results among students. Furthermore, it can cost a significant amount of capital to perform research projects, which enable a school to build specialized facilities and can also contribute to a strong reputation. While public schools rely on public funds for financial aid, a large endowment is essential for many institutions.

Hero and Beowulf

Epic heroes possess many traits that other characters lack. Among these are physical strength, bravery, and wisdom. These attributes aid the heroes with their journeys throughout the epic. Beowulf exemplifies each of these traits somewhere is the story. They aid him in his battles with monsters and allow him to be a leader to his people. These traits cause Beowulf to stand out among his peers and endear him to the reader. Beowulf is definitely a perfect example of an epic hero. Beowulf's physical strength, bravery, and wisdom characterize him as an epic hero.Beowulf's physical strength is revealed to the reader through his amazing feats and his unbelievable battles with mystical creatures. In lines 91 and 92 it states that Beowulf was the strongest man in the world. These words come from the Geats who are barbaric people to begin with. The fact that they speak so highly of Beowulf's strength is a testament to its truthfulness. After Beowulf arrives in Denmark he quickly travels to He rot to prepare for his battle with Grendel. In the lines following 307 it is stated that Grendel was instantly seized by Beowulf upon trying to clutch him.This is a feat that no man was able to accomplish before Beowulf's arrival. Beowulf's strength is also shown in his battle with Grendel's mother. In lines 465 and 466 it states that Beowulf was able to throw the she-witch to the ground. This only reemphasizes Beowulf's great physical strength. Finally, Beowulf's strength is shown in his battle with the dragon. Beowulf's battle with the dragon occurs when he is an old man. The fact that Beowulf is still able to defeat the dragon shows the reader the extent of his great strength.Beowulf's great physical strength is one of the characteristics that make him an epic hero. The second characteristic that Beowulf embodies is bravery. In the beginning of the story it is made obvious to the reader that Beowulf has led a glorious youth. He preformed feats that no other man would dare try. As soon as word of Grendel reaches the shores of Geatland, Beowulf makes it his personal mission to defeat the monster. During the battle with Grendel on lines 295 and 296, Beowulf lies patiently on the floor and waits for Grendel to seize him.He also chooses not to use weapons to fight the monster. When pursuing Grendel's mother on lines 307 and 308, Beowulf jumps into the lake without a second thought. As he sinks to the bottom the thoughts crossing his mind are of the battle to come and the glory he will gain. During the battle with the dragon Beowulf continues fighting alongside Wiglaf even after all others abandon them. One of the main sources of Beowulf's bravery is his belief that â€Å"God† is in control. Beowulf believes that he has no control over his own death.With this knowledge Beowulf can storm into battle with no hesitations. Beowulf's bravery is the second characteristic that makes him an epic hero. The final characteristic that sets Beowulf apart as an epic her o is his wisdom. From the beginning of the story Beowulf is painted as a wise individual. On the long journey from Geatland to Denmark Beowulf serves as the boat captain. He is the figurehead of his fellow Geats and is shown as the leader. During his battle with Grendel, Beowulf displays superior fighting ability and combat strategy.By pretending to be asleep, Beowulf surprises Grendel and gains the upper hand in the fight. When Beowulf is dragged into the she-witches lair he quickly realizes that his weapons have no effect. Beowulf sees the giant's sword hanging on the wall and draws it. Using the sword he severs the head of Grendel's mother and wins the battle. When Beowulf was faced with an unusual condition, he used his wisdom to guide him through the battle. Eventually Beowulf became the ruler of Geatland. His years of fighting had given him the wisdom to effectively lead his people.There he would rule until his return to Denmark and his final battle with the dragon. Beowulf's strength is the third quality that defines him as an epic hero. Beowulf is one of the most popular examples of an epic hero. His physical strength, bravery, and wisdom set him apart from all other warriors. Beowulf was able to defeat enemies that no other man would challenge. Even though Beowulf was eventually slain in battle, he died never knowing defeat. This is an accomplishment that few heroes make. Beowulf represents one of the most notable epic heroes in history.

Leading and managing changes Essay

1.1Background The David Jones is iconic department store in Australian retail industry, but the net profit of David Jones has been decreasing because of the rapid retail environmental changes, unhealthy cultures, and global online attack. The problems of declining net profit in David Jones are creating make it essential to apply the most suitable change management for company. 1.2Aim The aim of this report is not only applying the change management theory, model, and style for David Jones and David Jones’ CEO, Paul Zahra, but also supporting the arguments through case studies in order to find practical solution. 1.3Scope This report presents the view that a positive model, modular transformation and incremental change are the most suitable change management theory that can be implemented for David Jones. Also, a coercive style of management is a suitable style of management for David Jones’ CEO, Paul Zahra. The findings and analysis of performance for each theory, model, and style are justified by a critical comparison of the change management theories, models, styles and practical problem solution cases. Moreover, the improvements for David Jones’ restructure are discussed. 2.0 MODEL OF PLANNED CHANGE FOR DAVID JONES 2.1 David Jones issues David Jones is the oldest department store in Australia and was established in 1838. Until 2010, David Jones worked successfully in the Australian market, especially from 2007 to 2010. During that time, the net profit of David Jones increased from $109.5 million to $156.5 million, but the significant growth in the net profit dropped slowly from $156.5 million to $101.1 million by 2012. The slow decrease in the net profit of David Jones is caused by unhealthy organisational culture, global online retail attacks and retail environmental changes. In order to reconfirm David Jones’s importance in the Australian retail and consumer market, the best planned change model has to be chosen for David Jones. 2.2 Comparison of  planned change models for David Jones Cummings and Worley (2009) summarise the differences of three major models of planned change. The first one is Lewin’s change and action research model, which are more focused on fixing problems than concentrating on what the organisation does well and gaining those strengths. Also, Lewin’s change model, a three-stage model, claims that adaption of these forces maintain the status quo, which leads to efficient strategy for change (Waddell, Cummings & Worley 2007). The three-stage of Lewin’s change model is shown in figure 1(A). Moreover, the action research model is a cyclical process, which is determined by eight steps that fix problems using frequent research (Cummings & Worley 2009). Eight steps of action research are shown in figure 1(B). On the other side, a positive model focuses on positive dynamics in an organisation that improves the extraordinary results (Waddell, Cummings & Worley 2014, p. 39). This model is described by in five steps, which is shown in figure 1(C).   Figure 1: The comparison of planned change models (Cummings & Worley 2009, p.25) 2.3 Positive model for David Jones According to David Jones case study, the positive model of planned change is the best suitable one for David Jones because: †¢ it is proved that in order to survive with today’s uncertainty and huge competitive business environment, organisations need to focus on more business environmental changes than fixing the organisational problems (Waddell, Cummings & Worley 2014, p. 39) †¢Cristian-Liviu (2013, p. 1690) notes that the resistance for change causes the failure of strategic implementation because employees try to maintain their culture. Also, Ruxandra and Camelia (2013, p. 127) noted that resistance to change may create lots of problems during the change process such as activity drawl, activity slow-down, delays in launching and change process, and delayed and inefficient performance. †¢Sandra and Tracy (2012) indicate that bad news in business leads to poor financial outcomes, and external and internal crisis. †¢ it is supported by case studies that the linkage between inability of identifying of retail environmental changes and Zahra’s new rescue plan for David Jones failed because after the new rescue plan of Zahra, net profit and share price continued to decrease. Moreover, the case study said that ‘it may be a good five years before strategy can be assessed properly’ (Waddell Waddell, Cummings & Worley 2014). On the other hand, Lewin’s change model or action research model is not suitable for David Jones case because of focusing on more problems in the organisation than concentrating on retail environmental changes. The result of implementation of Lewin’s change model or action research model would be led to the strategic failure. The possibility of positive model of planned change for David Jones makes it necessary for the company to use positive model. 3. THE CURRENT RESTRUCTURE OF DAVID JONES 3.1 Current business restructure analysis Even though this report agrees with the current restructure and rescue plan of David Jones, which were divided main three parts including eleven subparts that are renovating store policies, focusing its core strengths, and transferring from traditional business to technologically oriented business, I want to add two main parts that are sustainable training and focused marketing strategy. 3.2 Recommended changes for David Jones In order to achieve optimum results, David Jones should consider the following choices. †¢Sustainable training: The rapid changes in business environment are needed and required to learn every innovations for business organisations in order to dominate their current market. It is proved that in the today’s interconnected world, the success of organisations and teams depends on how much they can use and operate new information and communication technologies that changes business environment (Ancona, Bresman & Caldwell 2009). Also, Blanchard (2009) notes that coaching for their employees lead to successful organisation within the unpredictable changes, but the new rescue plan has no any special training and coaching for their employees. It is a big disadvantage of new rescue plan that has been causing the decreasing net profit of David Jones and failure of strategic implementation. Moreover, it is supported by case study that although David Jones had excellent customer service in the fast, but it has decreased over the years. †¢Focused marketing strategy: Another disadvantage of new rescue plan is unfocused marketing strategy. According  to case study, new strategic plan did not include any focused marketing plans, which target customers and profitable markets. Also, David Jones could not identify changing customer behaviours and profitable buyers. It is supported that new economic order has changed the buyer’s market, which is that a twenty-four percent of buyers in Australian population has balanced fifty-four percent of discretionary spending, but David Jones has been concentrating on fifty percent of buyers, who are only twenty-four percent of discretionary spending in Australian population. The combination of lack of marketing strategy and non-target sales activities cause the inefficient strategy implementation. In addition, Nemcova & and Dvorak (2011) state that the strategic management of electronic commerce is concentrating essentially on customers, but David Jones focuses on more result s than concentrating on customers. The possibility of sustainable training and marketing strategy supporting strategic implementation of David Jones makes it necessary for the David Jones to add sustainable training and marketing strategy for their strategic plan. 4. SCALE OF CHANGE FOR DAVID JONES 4.1 Comparison of scale change During the unpredictable changing business environment, the scale of change helps to organisation in order to achieve optimum result how much change the organisations. This process is divided by from fine-tuning organisational development to corporate transformation (Waddell, Cummings & Worley 2014, p. 52). †¢Fine-tuning: This changing process is performed at divisional or departmental level as matching between organisation’s structure, strategy, people and activities. †¢Incremental change: Change process that in order to match changing environment, corporate business structures, strategies and management process are always adapted. †¢Modular transformation: Modular change concentrating on more changing and redesigning one or more division than changing whole organisation. †¢Corporate transformation: Corporate transformation brings about whole organisational transformation. 4.2 Suitable scale of change for David Jones For David Jones, the most suitable of scale of changes are modular transformation and incremental change the reason why: †¢ in the case study, although new strategy of David Jones was implemented in order to match  between retail environmental change and strategic performance, it faced failure because of performing too late. Firstly, in order to dominate online and retail market, David Jones has to use the modular transformation that renovates some divisions including information technology, marketing and strategy and human resource. By renovating the inability of divisions, it reduces the risk of failure of strategic implementations because Poblador (2014) notes that the failure of organisational strategy is sometimes caused by unexpected responses from the organisation itself, especially its employees behaviours that indicates corporation culture. It is showed that using corporate transformation is more risky for David Jones than using modular transformation. After that modular transformation process would be finished and are matched business environment changes, David Jones should be applied to use incremental change process in order to maintain and dominate its retail market. Also, it is supported that the maintenance of changing environmental situations are accomplished by keeping incremental changes (Poblador 2014, p.143). †¢fine-tunning is not suitable for David Jones because between 1960s and 1970s fine-tuning was implemented successfully in organisation, but today’s uncertainty business environment is needed by different change process (Waddell, Cummings & Worley 2014). Also, case study said that even though unhealthy organisational culture have been causing for losing net profit of David, main reason for David Jones is retail environmental change especially online trade, new economic order and technological revolution. On the other side, the decrease of net profit in David Jones was caused by online trade, new economic order, technological revolution and unhealthy organisational culture, and majority of profit in David Jones is earned by traditional department stores, it is not necessary to make whole organisational change in order to match retail environmental changes. It is proved that Ford Plastics was implemented in an organisation-wide change in order to match its external environmental change, but it faced the failure soon (Graetz et al. 2002, p.32). All the evidence shows that the modular transformation change and incremental change are the most suitable change process for David Jones. 5. APPROPRIATE STYLE OF MANAGEMENT FOR DAVID JONES’ CEO PAUL ZAHRA 5.1 Comparison of style of management The style of management is described by Australian researchers Doug Stace and Dexter Dunphy. The main idea of the style of management is that unpredictable business environment is required and demanded the rapid changes for organisation to achieve their strategic goal. Using style of management for organisation, which is described by from collaborative to coercive, makes it easier to be employed (Waddell, Cummings & Worley 2014). †¢Collaborative: Employees are involved in making significant decisions about organisational future and change performance. †¢Consultative: According to consultation, employees bring about organisational change, but for goal setting, they involved limited participation. The goal setting is done by expertise or responsibility. †¢Directive: Main form of significant decisions about organisational future and change performance are made by managerial authority and direction. †¢Coercive: One of forcing authorities, which are outside parties, managers and executives imposes to change on key group in the organisation. 5.2 The most suitable style of management for Paul Zahra For David Jones’ CEO Paul Zahra, the most affordable style of management is coercive because: †¢the long term performance results of sixty teams are estimated that empowering team leader leads to higher work performance for teams over time than a directive team leaders because of higher level of team coordination, empowerment, learning, and mental model development (Natalia, Matthew & Henry 2013). †¢collaborative and consultative are not suitable for David Jones because Phil (2012) estates that the most efficient change management for overpowering companies were brought by the combination of concentrated clear vision of change and sponsorship from the top. Also, it is supported that the commitment of top management for change creates energy for action within the organisation, which leads to a successful vision (Graetz et al. 2002). †¢according to Jaroslav (2013), the directive style leads to lower capacity for the average bank sales clerks, which is proved by banking sector in Slovakia. It is showed like David Jones current situation the reason why net profit of David Jones has been decreasing, which proves that the directive style is not suitable for David Jones. †¢ case study said that not only the board of David Jones has been supporting Zahra’s vision of change, but also the rapid changes in retail business  environment are needed to manage quickly because the business environment changes and competitors do not wait David Jones. To sum up, the possibility of coercive management style to be used successfully in rapid changes business environment makes it necessary for the David Jones’ CEO Paul Zahra to use coercive management style. 6.0 Conclusion It can be seen that the most affordable suitable planned change model for David Jones is Positive model, and scale of change is modular transformation with incremental change. Moreover, the best suitable style of management for David Jones’ CEO Paul Zahra is coercive. Furthermore, even thought this paper agrees with the restructure of David Jones, sustainable training and focused marketing strategy would be added for David Jones’ rescue plan. In conclusion, the combination of Positive change model, modular transformation with incremental change, coercive style of management, sustainable training, and focused marketing strategy will support David Jones’ strategy achievement. Also, the improvements for David Jones’ restructure are discussed.

Essay questions - Assignment Example Constitution were universal and should be shared with everyone. By the end of the 19th century, the Monroe Doctrine was to come into full effect in a war with the Spanish. Not only would the Americans take control of Spanish possessions in the Caribbean such as Cuba, Puerto Rica, and other islands, but as the war expanded so would the remit of the Monroe Doctrine. The United States would gain control of the Philippines, far from its own shore, and attempt to remake the Spanish colonialism political system in its own image. The result would be a bloody conflict fought with Filipino insurgents that would take America many years to quell. Following the American victory over Spain and the taking of the Philippines, there was a great deal of tension between the U.S. and the locals. This came to a head in 1899 when American soldiers shot some Filipinos. Things quickly got out of hand with both sides raising armies and fighting conventional wars. The Americans rapidly defeated the convention Filipino forces, killing two of their best generals and pacifying many of the urban areas. During this period, the President appointed distinguished Americans to investigate conditions in the Philippines and report back on ways to improve the administration of the country. The first Commission’s report was a rejoinder to those who argued America had no place in Southeast Asia: Should our power by any fatality be withdrawn, the commission believe that the government of the Philippines would speedily lapse into anarchy, which would excuse, if it did not necessitate, the intervention of other powers and the eventual division of the islands among them. Only through American occupation, therefore, is the idea of a free, self-governing, and united Philippine commonwealth at all conceivable. And the indispensable need from the Filipino point of view of maintaining American sovereignty over the archipelago is recognized by all intelligent Filipinos and

The Airplane is the Safest Transport Essay Example | Topics and Well Written Essays - 250 words

The Airplane is the Safest Transport - Essay Example The media often emphasize that the occurrence of plane crashes is exceedingly infrequent. In fact, these statistics suggest that one is more likely to die driving to the airport than flying across the country (Curran 237). Airports are equipped with top-notch facilities to facilitate traffic control both at the airports while landing and in the sky during flight. Pilots have a multitude of assistance helping them from takeoff through landing with Control. Traffic control crews both at the departure point to the landing. These crews are in rotation around the clock 24 hours a day. Where they make use of radar procedures to track the planes in the sky, provide directions, authorization and the information about flight state of affairs. Pilots are not the only people in charge of safety in the air. However with road transport t, his is not the case, the driver has no one to help him or her in watching the road while he or she is driving. These drivers to multitask that required divided attention thus less focus. The pilots undergo rigorous training long before they get entrusted with the responsibility of flying a plane. The training takes more time to complete than a typical driving test does. A driving test requires one merely to demonstrate a mastery of steering, braking, signaling. Once the applicant shows a characteristic, he or she gets a driving license and considered fit to drive. Moreover, one must go to flight school to acquire a license. The training period enables pilots to enhance the ability of the pilot to gain some of the required experience (Curran 242). Customarily there are two pilots in any aircraft. In case anything is wrong with one pilot, the other one can typically take over. In addition, a crew onboard ensures all the passengers adhere to the rules of the aircraft to prevent any accidents.

Employees of the organization are encouraged to respect each other and strive for continuous improvements. Toyota was selected for conducting the current analysis as the company operates in the U.A.E. Toyota UAE has been successful at implementing a strong customer base in the U.A.E. The company has been successfully holding its core corporate values in the Middle-East while catering to the specific needs of the consumers. Toyota U.A.E plays an important role in the automobile industry of the nation, contributing significantly in terms of revenues and productions. The values and mission of the company is described as follows: Inventory management is one of the most critical decisions which mangers are required to take. The success of an organization depends upon a proper inventory management process. Inventory management involves establishing proper control over the flow of stock of goods into and out of the business. The process involves taking critical decisions regarding the level of stock to be brought to the factory floor, the level of stock required to be dispatched, the time interval for placing orders for raw materials and the duration of storage. Factors such as the duration of storage of inventory and the quantity of materials orders affect the cost of production. Hence firms are required to take inventory related decisions through careful planning and long term analysis. Warehousing, cost, delivery time and turnover time are the most important aspects which mangers consider before taking decisions relating to management of inventory (Stevenson and Hojati 96). Toyota essentially follows the just-in-time inventory management concept. Based upon the just-in-time inventory concept, raw materials are brought to the factory floor only after order for the same have been received from the dealers and customers. The

Managing New Media Projects Essay Example | Topics and Well Written Essays - 2500 words

Managing New Media Projects - Essay Example It has been contended that the surfacing of novel, digital technologies hinted a fundamental shift of who is in control of information, experience and resources (Croteau and Hoynes 2003, p. 322). Likewise, it was inferred that new media will: 1) change the implication of geographic distance; 2) facilitate massive swelling in the volume of communication; 3) offer prospects of increased speed in communication; 4) present greater chances of interactive communication; and 5) permit structures of communication that were formerly separate to be integrated and get linked (Croteau and Hoynes 2003, p. 303). Accordingly, there are discussions between many academics indicating that the new media, predominantly the internet, offer the prospects for a democratic postmodern public sphere, where citizens can contribute and involve themselves in educated, non-hierarchical deliberations relevant to their social structures. On the other hand, those opposing the constructive assessments of the probable social effects of new media have put forward the notion that the switch to new media has seen a handful of influential and potent global telecommunications organisations that have achieved a level of large-scale influence which was previously inconceivable. Contemporary inputs to the field have underscored the constructive and off-putting prospects and tangible propositions of new media technologies, signifying that a few of the earlier works on new media studies were guilty of technological "determinism," wherein the upshots of media were determined by the technology itself, rather than mapping out the intricate social networks that manage the progress, financial support, execution and future advance of any technology (Lister et al 2003; Flew 2002, p. 13; Durham and Kellner 2001; Marmura 2008, p. 247). -- P R O D U C T I O N P L A N - (GreensForYou) Project Analysis An English website for a new chain of organic food stores based in London, GreensForYou targets male and female customers aged 25-45. It seeks to disseminate information to the public basic details regarding the stores' location, wide-ranging use of images showing the origin of the food being sold, the ethical strategies used in food production, its home delivery services and most especially the project's campaigns supporting fair trade. Likewise, it has an e-commerce component, a flash mini-game about organic food, an interactive quiz about the benefits of fair trade and an educational segment featuring interactive activities and educational content for teenagers aimed to instruct them on the essentials of organic food. One critical issue in this undertaking is with regards to copyright clearance and intellectual property. Unless all of the content used in the GreensForYou project is originally created by the production team, the group really needs the suitable copyright clearances and even if site owner is dealing with content created by others or by its very own project team, the new intellectual property the site has created likewise needs to be protected; more so in the case of audio or music, the rights of the performer, record producer and copyright holder, have to be cleared (CHIN 2002, p. 42). With this issue are some limitations that need to be appraised. The growing accessibility and dropping cost of bandwidth implies that more and more

Time Travel Essay Example | Topics and Well Written Essays - 2500 words

Time Travel - Essay Example And having thought what to do, we can only do it now: while the time for action is future we can only await it, and once it is past it is too late. When it comes to time travel, the perception of difference somewhat diminishes, according to various scientists theories presented in various ways we conclude that most of them agree with the notion that in order to travel back in time one has to travel faster than the speed of light. Only in such condition one can travel in time. Along with the speed of light, there are other three factors that are considered for a person in order to travel. Those factors or four elements on which time travel is based are considered at the very core of science fiction, which are: Foote has his own unique perception according to which traveling whether it be the future or the past is reasonable to justify and can be universally accepted by the judgment that a person is always involved in traveling all the time, every minute and at every second and particularly in his sleep because as we sleep our consciousness takes a several hour-long leap into the future. It is no wonder that this scenario has a respectable, if dateable, past in the literature of science and fiction. But nothing, nothing except dream and memory, stands in relation to travel to the past as sleep does to travel to the future. Travel to the past takes all customary notions of cause and effect, as Foote believes in the laws of thermodynamics. (Foote, 1991, p. 9) which suggests, "heat is a form of energy that is in motion". Let us examine this quotation what Foote has said. Heat is a form of energy and so is the man. A living energy in the form of meat and flesh. A man if moves in motion obviously generates and radiates energy and if a man travels faster than the speed of a light it is for sure that he would wake up in an environment which is quite old and ancient for him. Faster than light travel No doubt Foote has related human capabilities with those of the speed of light. Here is the theory presented by Foote based upon FTL travel first: it is true that the physicists of the tribe have devised a mathematical fiction called the tachyon, which, if it exists, must travel faster than light. Greatly simplified, the logic runs like this: in the universe we observe, we postulate the existence of tardyons, particles which must travel more slowly than light, and luminons, which always travel at precisely the speed of light. The more energy one puts behind a tardyon, the faster it travels and the heavier it gets; but as one approaches the speed of light, vast increases in energy are required to accomplish minuscule increases in speed. Only an infinite amount of energy which is not available to us in this universe will suffice to bring a tardyon to the speed of light". (Foote, 1991, p. 9) There is indeed an asymmetry in respect of past and future in the way in which we describe events when we are considering them as standing in causal relations to one another; Macbeath explains this as it reflects an objective asymmetry in nature and thinks that this asymmetry would reveal itself to us even if we were not agents but mere observers.

Transvestic Fetishism - Research Paper Example This condition mainly affects the males and females are not known to suffer from it. Frenchman Chevalier d’Eon de Beaumont was suffering from this condition and hence after him this disorder was also given the name of eonism. The patients who suffer from this condition are also known as transvestites (Laws et al 2008 & Zucker et al 1995). The patients who suffer from transvestic fetishism have a tendency to collect the clothing of females which include everyday clothes as well as undergarments and other things that is shoes, socks and nightdresses. They may also like wearing these and then taking their photographs dressed in the female attire. By performing these acts the subject gets sexually aroused and has achieves sexual pleasure. The onset of this condition is mainly after the attainment of puberty and many cases of this condition cannot be reported because transvestites basically perform these acts in private rather than openly. Another important reason behind this is the fact that transvestites are mainly heterosexual and may enjoy normal relationships with women to an extent that they may even be married. Transvestic fetishism patients also have another important characteristic that they show patterns of both male as well as female personality (Laws et al 2008 & Zucker et al 1995). According to the Diagnostic and Statistical Manual of Mental Disorders (DSM) of the American Psychiatric Association, there are four important characteristics which basically define a person as a transvestite. The first characteristic is the finding of the factor of wearing the attire of the opposite sex. The second important finding is the fact that this dressing should be coupled with the attainment of sexual gratification and pleasure. Also this condition is mainly seen in men who are normal biologically and that they are attracted to females that is they are heterosexuals. In the year 2000, The DSM-IV-TR standards for

Edgar Allan Poe Essay Example | Topics and Well Written Essays - 1250 words

Edgar Allan Poe - Essay Example Wordsworth attempts to prevent the poetic figure from losing its natural passion, from repeating itself as an empty, mechanical device of style... Poe writes a poem packed with cliches in order to show that those cliches cannot succeed in remaining empty, that there is also a natural passion involved in repetition, that the mechanical is of a piece with the profoundest pain. (Bloom, 24) Poe was born on the 19th of January 1809 in Boston, Massachusetts, to David Poe Jr. and Elizabeth Arnold Hopkins Poe- both established actors. He had an older brother named William Henry Leonard Poe and a younger sister, Rosalie Poe. In 1810, Poe’s father abandoned them, and within a year, their mother died of consumption also known as tuberculosis, a highly contagious bacterial infection. Poe was too young to be influenced by the death of his mother at the time it occurred, but later reflections in adulthood led him to grieve for how much better his home life would have been, if he never had t o live with a foster family. His mother’s death by the dreaded disease of the time, tuberculosis, would be a common source of death in others who would matter much later in his life. Edgar and his brother and sister were split up and sent to live with different families; Edgar went to live with a man by the name of John Allan who was a Scottish tobacco merchant living in Richmond, Virginia; who was always abusive toward him. . â€Å"Although Poe seemed happy, deep inside he was confused. Because he was never formally adopted, he felt uncertain about his position in the Allan family and his doubt often made him cross and dejected.† (Poe & Bagert, 5)They fought constantly, and Edgar finally enlisted in the Army just to get away from him. John Allan was often under the influence of alcohol during the fights but out of respect for the Allan Family, Edgar took the middle name of Allan. Edgar began to write poetry regularly when he was in his early teens. He fell in love wit h a girl named Elmira, and they eventually pledged themselves to each other. In 1826, he was sent to the University of Virginia to study law. His rich foster Father John Allan with whom Edgar always had a chaotic relationship gave him a mere $100 to cover his yearly expenses that totaled to an estimated $450. Under such circumstances, the young man got highly indebted and began gambling in an attempt to make up for his losses. On top of this, Elmira’s letters to him had been intercepted by their parents and having received no encouraging replies from Edgar; she was persuaded to get engaged to another man. After this tragic event, Edgar began drinking seriously. He had little resistance to alcohol and easily became violent and irrational whenever he drank too much. By the end of the year, Mr. Allan pulled Edgar from the University and after loud and spiteful fights with his foster father; Edgar left home and made his way to Boston. In 1827, he published his first pamphlet of T amerlane and Other Poems, which is so rare nowadays that a single copy was sold in 2009 for $660,000. â€Å"This is known as the Black tulip of U.S. Literature†¦Ã¢â‚¬  (Wahlgren). However, at that time Poe enlisted in the army as Edgar A. Perry at the age of eighteen, stating on the application that he was twenty-two in order to earn a living. In 1829, after his beloved foster mother died, he applied to West Point military academy with the support of his commanding officer and foster father. By 1832, Edgar began to write fiction with the idea of entering story contests. He

The Qualities of a Friend Essay Example for Free

The Qualities of a Friend Essay Friends can come in different personalities, shapes, and forms. Someone could have a friend that is shy or outspoken. But to be a friend one must have certain qualities to be considered a friend. A friend must be trustworthy, honest, and loyal. One of the main qualities of a friend is to be trustworthy. To be trustworthy means that one would be able to tell the other secrets without worrying, that the friend would go and tell someone else the secret. Without trust, a friendship would not last. There would be drama and issues between the two where the friendship would crumble and would make the two hate each other. For a friendship to have trust and it lasts is one of the best things one could ask from a friend. Another quality a friend should have is honesty. Honesty means to be honest and to never tell a lie. If a friend has this quality one should keep them close by because they are dependable. An honest friend would not keep someone in the cold; they would always tell the other the truth. For example, if one asked the other about a decision that the other made if it was the right or wrong choice, that friend would give an honest answer. So being honest is one key factor of being a friend. Lastly, another quality is to be loyal. To be loyal means to never turn one’s back on the other; he or she would never leave the other behind. A loyal friend will always be on the side of the other and never leave the other behind. One could have done something selfishly, but if that friend has loyalty then he would still be a friend. Loyalty is a must if one would like to be considered a true friend. When people gain a friend in life that person will not be perfect. He will have many flaws just as anyone else. But for that person to be a great friend he or she would have these three qualities: to be trustworthy, to be honest, and to be loyal.

Tesco PESTEL Framework

Tesco PESTEL Framework Introduction Tesco is the largest organization in the UK and one of the biggest supermarket chains in the world. Tesco is one of the top three supermarkets in the world, Tesco operating over 3700 stores globally and employing over 440,000 people. The company operates in 13 countries outside the UK. There are many factors which contribute directly to the success of this leading super market chain. Business Strategy plays a pivotal role in the success of Tesco. Tescos History Tesco was founded in 1920s by Sir Jack Cohen, to setup high street grocery stores in and around London. Tesco name used for the first time in Edgeware London in 1929. The name was drawn from the initials of the companys tea supplier (T.E Stockwell), and Cohens own name. In 1930s when Mr. Cohen built a headquarters and warehouse in North London, its brand continually rises. In 1932 Tesco formally established as a private limited company. In 1947 Tesco stores (holdings) ltd floated on the stock exchange with a share price of 25p. In 1990s the company introduce a slogan Every Little Help, they also introduce Club card scheme in 1995. Tesco personal Finance was introduced in 1997, in order to provide its customers with a wide array of financial services, including visa card, and Tesco saving account in stores bank branches. Today it reported that group sales were  £51.8bn in the year to February 23 2008. Pre-tax profit rose to  £2.8bn. Company Analysis: PESTEL Framework Political Factors Tesco is operating in different countries, so due to its globalised operation its performance is highly affected by the Political and legislative conditions of these countries. According to Balchin, 1994 the Govt encourages the retailers to provide mix job from flexible and locally based jobs to highly skilled, higher-paid and centrally located jobs. (Balchin, 1994) Economical Factors Tesco is also affected by economical factors, such as costs, demand, prices and profits. Unemployment is the most important influential factor which decreases the effective demand for many goods. Basically Tesco is affected indirectly by the economic factor, but their affect on performance and the marketing mix can be learned. Social/Cultural Factors Due to the rapid change in trends, the company expand the amount of non food items available for sale. The UK customers have moved towards one stop and huge shopping, due to the variety of social changes. It also affected by Demographic changes such as population, female worker are increased, so the company will have to focusing added- value products and services. Technological Factors Technology factors are affected the development of many of the Tesco products. Both customers and company are capitalized from the Technology, because customer satisfaction mount for goods readily available, services becomes more quick and shopping more convenient. The lunch of the efficient Consumer Response initiative provided the shift that is now apparent in management of food supply chains. (Data monitor Report, 2003) The company uses the following technologies: Wireless Devices Intelligent scale Electronic shelf labelling Self check-out machine Radio Frequency identification (RFID) Companys Analysis: Porters Five Forces Threat of New Entrants The UK grocery market is primary henpecked by few competitors, including four major brands of Tesco, Asda, Sainsburys and Morisons that process a market share of 70% and small chain of Somerfield, Waitrose, and lidle with further 10%. However, due to the large operation they built their power to operating efficiency, one-stop shopping and major marketing mix expenditure. Hence, nowadays it possesses a strong barrier for new companies who crave to enter the grocery market. To become a market leader Tesco invest huge money in large chain, advance technology for checkout and stock control system that impact the new entrants and existing ones. Bargaining Power of Customers According to Michael Porter, the more products that become standardised or undifferentiated, the lower the switching cost, and hence more power is yielded to buyers. Porters M. (1980). Tescos famous loyalty card Club card keep the most successful customer holding strategy that tremendously increases the profitability of Tescos business. To fulfil customers needs, custom-make service, ensure low prices, better choices, constant flow of in store promotions enables brands like Tesco to control and hold their customer base. Bargaining Power of Supplier Tesco has negotiating better promotional prices from supplier that small individual chains are unable to match. And this is company policy and company main approach to have unparallel relationships with suppliers. Threat of Substitutes According to the Porters theory, General substitution is able to reduce demand for a particular product, as there is a threat of consumers switching to the alternatives (Porter M1980). However in the grocery market this can be seen in the form of product for product, new trends such as the way of small and convenient stores are emerging in the market. Bargaining Power of Competitors Tesco is operating in mature market, where growth is difficult, and consumer are extend demanding and advanced, large chains as company take place large amounts of consumer information that can be used to communicate with consumer. Therefore the preponderant market leaders have responded refocusing on price and value, whilst reinforcing the added value elements of their service. Analysis of Resources, Competence and Culture For the company, customer is first priorities, by the time of recession, a research shows that price are ranked as the most important margins not seen in twodecades. Therefore the company believe that their job is to help the customer with less spending. So the company launched value line, the famous blue stripes, the company would be able to provide the cheapest grocery shop in the country discounter included. The company maintain its position through a clear focus, well targeted product offer and excellent record both in product and format design. Core Competence Core competence is the processes that critically underpin the companys competitive advantage. Tesco primary target is to recognise that competition between businesses is as much a race for competence as it is for market position and market power. Hence, the Company have to focus the attending on competencies that really influence competitive advantage. Core competence is basically the process to develop the key area of a business in which the company expert, which bring a distinctive advantage over the competitors, and also critically connected with company long term growth. However, it will be important for Tesco to look at the generic level. Therefore in this case, Tescos expertise are most likely to mature central area of business where the most value added to its services and its devilries. For example, trust on Tesco brand prevarication at the heart of these services In addition, Core competencies of a Tesco have rather rigid, but a research shows that core competencies have to elastic, and it should be change in response to change in companys environment over the time. Therefore the company need to accommodate and create new idea and also new opportunity in the market. For example, Tesco launched its loyalty card and went into banking. Tesco able to enter into retailing of food and non food products was a clear distinctive brand proposition that had a focus on a properly define market section. The company also provide a strong and efficient customer service, based on a good customer relationship. Tesco Strategic Options: Generic Strategies Introduction: According to Porter (1985), competitive advantage arises from selection of the generic strategy that best fits the organisations competitive environment and then organizing activities to support the chosen strategy. These strategies are characterised by the company in response to their structure and environment of the organization. However to obtain a competitive advantage Tesco should follow one of the three strategies, which is developed by Porter. Cost Leadership Tesco accommodate the first strategy of cost leadership in which can endeavour the lowest costs in the market and offer its products and services to broad market at the lowest prices. The company are more focusing on the effective saving programme call Step-Change. By this programme the company delivered  £540 million of productivity and other saving in the year, which mostly reinvested in improving the shopping trip for customers. To reducing the amount of energy the company introduce better ways of working to improve the efficiency by making things better for customers, simpler for stop and cheaper for company. For example, according to a report, in the last year the company saved 52,000 deliveries to companys stores by using larger-fill-double-decked vehicles, which in turn have also 12 million road miles. Some other example of these projects which delivered substantial savings in the year includes: Saving in the Supply Chain-the company using more shelf-ready packaging and reconfiguring the depot network to increased vehicle utilisation and more productive work methods in depots and stores. For example the distribution cost more held in cash terms and reduced in percentage of sales terms. By this method the company achieved despite higher fuel costs. Installed Energy Saving-the company significantly invest in energy-saving projects across the business- such as new refrigeration, store lobbies and lighting, its helping the company to absorb utility costs. From the energy consumption the company fell by 8% last year despite business growth. Low wage employees- the company have around 31000 employees working in India as Global Support Centre, which provides IT and administrative support to UK and International operationsfrom software development to management accounting and payroll. If the company use another strategy of differentiation, the company then tries to offer a good services and product with unequal features that customers value. With the differentiation strategy the company created a brand loyalty for their offering, and price inelasticity on the parts of buyers. For example to achieve a better and more efficient service provide by the company to checkouts, many more customers didnt have to queue last year and customer continue to rank the company for speed of services at the checkout. Another example of this approach, the company have different brand product according to their feature, speciality, and reliability. Such as Tesco value, Finest, Organic etc Value Chain Primary Activities Inbound logistics According to Alex Laffey, we choose G-Logs logistics and transportation technology because their solution will support and enhance our low-cost, high quality approach to growth in the retail market. Major factors in our decision to select G-Log were the close and demonstrable fit of their software to our requirements, and their ability to rapidly deploy the solution in phases to meet our aggressive project time frame. G-log is providing visibility, optimization, and execution will enable the company to integrate their supplier, partners and logistics service providers, delivering real-time visibility of in transit orders, whilst optimising the transportation resources by both consolidating loads and selecting the most cost effective carrier. The G-log continues to shows to deliver significant result, and to provide value to its customers, in terms of improved customer services, reduced costs and enhanced competitive advantage. Outbound Logistics Outbound logistics is concerned with the delivering the product to the customer. The company adds value to its home delivery services. Tesco also trying to improve other tangible that have to be improved, such as parking facilities, trolley collectors, staff on self service checkout, and also to saying to customer hello hey and thank you with smiling face. The company making small improvements in everything with Every Little Help is about the company work together on the little things, its amount to a great deal. It keeps the focused on what matters most to customers. The company do not sacrifice all the other things that are so important to customers, such as not having to queue and being able to get everything that they want. Support Activities Company Infrastructure The company introduce software Real Time Integrator (RTI) which provides retailer with faster access to critical business information, through the provision and use of accurate, detailed, point-of-sale (POS) information. Sale data from individual store database will be routed to head office in XML to Microsoft server and Microsoft SQL. The solution handles 1500 sales transactions a second at peak times, which each have an average of between 50 and 100 items. To reduce the number not the on file items the first application for RTI will pilot for 120 stores, which improve the customer experience. Human Resources Management Tesco introduce a high commitment model which offers training and development to all employees. In addition the company extend their logo through their culture to prove their commitment to employees as well as to customers. The company continue to invest in customer services where training is also directly linked to pay, therefore the staff is motivated to learn and encourage their approach to customers and services and the provision of qualities. Conclusion With the research carried out, the company shows how the branding and effective service delivery can come in moving beyond splashing ones logo on billboard. The company made their market leader due to their successful and dynamic strategies. The company also made a powerful brand and powerful identities making their retailing concept into various and spending it out into the culture via a variety of channels. Such culture sponsorship, political controversy, consumer experience and brand extensions. The company change their culture and business environment very rapidly due to the high competitors pressure. The company also have to diversify the product and expand their strategies in order to sustain in its leading market position. This is already established by the company. Tesco need to make sure, to have the combination of good customer services, competitive pricing and efficiency when they launching a new product. Tesco has definitely has the potential and can compete with other store if the company get the above combination right.

Cocaine Drug Abuse

Cocaine Drug Abuse Cocaine through the ages: from elixir to poison. Cocaine through ages: from elixir to poison. Abstract: Cocaine, a plant alkaloid derived from coca leaves is a potent stimulant of CNS and has local anesthetic action as well. Historically, it was ingested in the form of chewing coca leaves, to suppress hunger and fatigue. With discovery of its local anesthetic properties, cocaine was introduced into world of medicine and a local anesthetic, but over last few decades, gained popularity as drug of abuse. Cocaine carries with it great potential for addiction and abuse. It is administered through various routes, smoking free-base crack and intranasal inhalation being most popular. Its primarily metabolized in liver and distributed to all body tissues. Due to lipid nature it tends to concentrate in brain and adipose tissues with chronic administration. Its mainly eliminated through kidneys, but saliva and stools are also routes of excretion. A number of health hazards have been shown to be associated with cocaine use including, cardiac abnormalities, psychological disturbances, addiction pot ential and renal failure with or without rhabdomyolysis. Acute and chronic cocaine toxicities with sufficient collected data are included. Techniques for detecting cocaine in blood including enzyme linked immunoassay and POCT (Point of care screening tests) have also been discussed. An analysis of recent trends in cocaine uses have been studied and presented along with graphical illustrations of epidemiological evidence to support the data. Introduction and objective: Objective: to display how cocaine has evolved through time in its uses and available forms, from simple coca leaf chewing custom of South Americans in 2500 BC to modern forms of freebase-coke among others as one of the most commonly abused toxic drug. Methodology: Data was mainly collected from electronic resources, but text on immunology and pharmacology was also consulted. From electronic sources, I mainly used search engines using a number of keywords including ; history of cocaine, crack, pharmacokinetics of cocaine, mode of action , coca leaf, acute cocaine poisoning, chronic cocaine toxicity, Karl Koller, Sigmund Freud, Immunoassay, etc. I also went through a number of journals available online, and a number of researches conducted which related to cocaine. My aim was to find changes in cocaine use from its discovery to date, and show, with help of collected data, that it has moved in a negative direction. Brief history: Cocaine, use of which, according to some sources, date back to at least 1200 years, has now, rightfully, earned itself a place in drugs of abuse list among others like Caffeine, Nicotine, Amphetamine, etc. To date, cocaines uses have evolved from gaining popularity as topical anesthetic agent, and as component of energizing drinks to becoming one of the most abused drugs in the world. It is a powerfully addictive stimulant drug, which acts by interfering with cerebral and peripheral synaptic transmission among neurons. Mode of action has been described in greater detail later in pharmacodynamics section, but for brief introduction, it interferes with reuptake of, and thereby enhance duration of action of, monoamines, dopamine, serotonin and nor epinephrine Brain PF et.al (1989). It also produces membrane stabilizing effect, more commonly referred to as local anesthetic effect. Latter is achieved through modulation of voltage gated sodium channels and consequent blockade of sensory im pulses conduction from that part of the neuron to central nervous system. Brain PF et.al (1989) Earliest records of cocaine use reveal it to be a part of South American custom of chewing coca leaves. This use is believed to date back to 2500BC. Steven Cohen (1981) Practice of chewing mixture of tobacco and coca leaves was defined by Nicolà ¡s Monardes, in 1569, to induce â€Å"great contentment†. Cocaine is the active component of coca leaves, which also contains nicotine. Karch SB (1998). In 1859, Italian doctor, Paulo Montegazza, after witnessing coca use by natives of Peru, and getting mesmerized by it, decided to study the effects of cocaine on himself. After his studies he concluded his findings into a paper in which he declared cocaine to be medically useful in treating furred tongue in the morning, flatulence and whitening the teeth. Steven R. King (1992). In 1863, French chemist, Angelo Mariani, introduced popular cocavine, Vin Mariani. Vin Mariani wasproduced from mixture of 6 mg coca leaves per fluid ounce of Bordeaux wine. Courtwright DT (2001) Angelo Mariani, creator of Vin Mariani, which later became the hallmark of cocavines was honored with Vatican gold medal by Pope Leo XIII for this achievement. Ethanol, a component of vin mariani, is believed to extract cocaine from coca leaves. In 1884, the concept of cocavine was adopted by John S. Pemberton, with introduction of Pembertons French Wine Coca. After prohibitions imposed on cocaine use and manufacture of cocaine-containing products including cocavine in 1885, Pemberton introduced carbonated, non-alcoholic form of Vin Mariani and called it Coca-cola. Richard Ashley (1975). From 1906 onwards, however, after Pure Food and Drug act was passed, decocainised forms of coca were used for manufacture of coca-cola. In 1884, Austrian physician Sigmund Freud, recommended cocaine for treatment of morphine and alcohol addiction. A strategy that was later employed in 1879 when cocaine was used to treat morphine addiction. Steven Cohen (1981). In 1985, use of cocaine for induction of spinal anesthesia was accidentally discovered by American neurologist Leonard Corning while he studying the effects of cocaine on spinal nerves in a dog and accidentally pierced the dura matter. Corning JL (1885) Cocaine was, however, not used as anesthetic in spinal surgery until 1989 when first planned cocaine induced spinal anesthesia was administered in a surgery, by August Bier. A. Bier, (1899) Coca leaves have traditionally been used as suppressants for fatigue, thirst, and hunger. Its use has now been limited to Andean countries, where coca leaf chewing and coca tea consumption are still practiced. Industrially, coca leaves serve as source of drug cocaine, and in some cosmetic and food industries, including coca cola. Richard Ashley (1975) From 1980s to date, cocaine has gained popularity as drug of abuse, and has widely replaced heroin and other narcotics as drug of abuse, being used in different forms and administered via various routes. Richard Ashley (1975) Discovery: Discovery of cocaine, as local anesthetic, is claim to fame for Austrian ophthalmologist, Karl Koller. Kollers name is credited with demonstration of anesthetic effect of cocaine, in 1884. Karl Koller was a close associate of Sigmund Freud who in same year recommended cocaine to be employed in treatment for morphine and alcohol addiction. Hruby K (1986). Koller studied effects of cocaine on eye by applying the drug to his own eye and later pricking it with pins. He presented his findings to the Heidelberg Ophthalmological Society in same year. Hruby K (1986) After successfully experimenting on himself, Koller used cocaine as local anesthetic in eye surgeries, a use that continues to this day. Cocaine was later employed in other fields including dentistry for induction of local anesthesia, Today, however, cocaine has largely been replaced by other local anesthetic agents like lidocaine, xylocaine, bupivacaine, etc, which produce local anesthetic effect as efficiently and do not carry potential for abuse.Hruby K (1986) Isolation: Friedrich Gaedcke, aGerman chemist, was first person to successfully isolate cocaine from coca leaves, in 1855. An improved isolation process was, however, developed by Albert Niemann, a Ph.D. student at the University of Gà ¶ttingen in Germany, in 1859. Niemann wrote a dissertation describing steps of isolation titled, â€Å" ÃÅ"ber eine neue organische Base in den Cocablà ¤ttern† (On a New Organic Base in the Coca Leaves), which was published in 1969. F. Gaedcke (1855) Formal Chemical Name (IUPAC) for cocaine: (1R,5S)-methyl 8-methyl-3-(phenylcarbonyloxy)-8-azabicyclo[3.2.1]octane-2-carboxylate. Medicalisation and popularization: Ever since its discovery, cocaines medical uses were quickly exploited through research and experimentation. Spanish physicians described first medical uses of cocaine as early as 1596, but the use of cocaine did not become more widespread until 1859, when Albert Niemann isolated the drug from coca leaves. Soon after it was isolated, cocaine was used to try to cure almost all the illnesses and maladies that were known to man. (Albert Niemann 1860) 1859s Montagezzis discovery about cocaine being useful in treating furred tongue in the morning, flatulence and whitening the teeth, was one of the earliest recorded studies that signified possible medical importance of cocaine. In 1879, Vassili von Anrep, of the University of Wà ¼rzburg, demonstrated analgesic properties of cocaine in an experiment that he conducted on a frog. He prepared two separate jars, one containing cocaine-salt solution, other containing salt water serving as control. One of frogs legs was submerged in cocaine solution and other in control followed by stimulation of leg in different ways. Reactions in two legs varied considerably. In the same year, cocaine began to be used in treatment of morphine addiction. The commercial production of purified cocaine gained momentum only in the mid-1880s. Its greatest medical value was in ophthalmology. Eye-surgery stood in desperate need of a good local anesthetic. This was because in eye operations it is often essential for a conscious patient to move his eye as directed by the surgeon without flinching. Karl Kollers demonstration of anesthetic properties of cocaine in 1884 was an important breakthrough establishing cocaines importance, medically when it was introduced in Germany as local anesthetic for eye surgery. (Altman Aj et.al 1985) Kollers discovery was later followed in 1985 by Leonard Cornings accidental demonstration of cocaines use in induction of spinal anesthesia, which became formally employed in spinal surgery in 1989 when first planned cocaine induced spinal anesthesia was administered by August Bier. Medical use of cocaine has largely been restricted to induction of local anesthesia. Even as local anesthetic agent, discovery of hazardous effects of cocaine use led to early development of safer alternative drugs like lidocaine, etc. One of its first non medical uses of cocaine was in military. In 1883 Theodor Aschenbrandt administered cocaine to members of the Bavarian army. It was found that the drug enhanced their endurance on maneuver. His positive findings were published in a German medical journal, which brought the effects of this wonder drug to a wider medical audience, including Sigmund Freud. Cocaine was sold as over the counter drug until 1916. It was widely used in tonics, toothache cures, patent medicines, and chocolate cocaine tablets. Prospective buyers were advised (in the words of pharmaceutical firm Parke-Davis) that cocaine could make the coward brave, the silent eloquent, and render the sufferer insensitive to pain. Cocaine was a popular ingredient in wines, notably Vin Mariani. Coca wine received endorsement from prime-ministers, royalty and even the Pope. The Vatican gold medal that Angelo Mariani received for it will forever signify the popularity of cocaine through that period of time. By the late Victorian, era use of cocaine had appeared as a vice in literature, for instance, Arthur Conan Doyles fictional Sherlock Holmes. . Number of admissions to drug treated programme in each year is plotted against time for both cocaine and heroin. Graph clearly displays the shift in trend from use of heroin towards cocaine. A combination gaining popularity is speedball, which is formulated by mixing heroin with cocaine. From 1980s to date, cocaine has gained popularity as drug of abuse, being used in different forms and administered via various routes, as evident by figure above which displays the escalation in crack / cocaine usage with concomitant reduction in heroin use. Prohibition: In first part of the twentieth century, with addictive properties of cocaine becoming more apparent with studies, cocaine found itself legally prohibited. Harrison Narcotics Tax Act (1914) outlawed unauthorized sales and distribution of cocaine incorrectly classifying it as a narcotic. In United Nations 1961 Single Convention on Narcotic Drugs, cocaine was listed as Schedule I drug, thereby making its manufacture, distribution, import, export, trade, use and possession illegal unless sanctioned by the state. In 1970s controlled substances act, cocaine was listed as a Schedule II drug in United States. It carries high abuse potential but also serves medicinal purpose. It is a class A drug in the United Kingdom, and a List 1 drug of Opium law in the Netherlands. Modern Usage: In late 90s and early 2000s, crack became very popular among Americans and in past few years has also taken its toll on UK. According to an estimate, U.S cocaine market exceeded $ 70 billion in year 2005, demonstrating the popularity of this menace. News reports are flooded with celebrity arrests on charge of cocaine posession or use. A section on recent facts and figures related to cocaine discusses the modern trends in greater detail later. Addiction potential: Along with amphetamine, cocaine is one of the most widely abused drugs in the world. Powerful stimulant properties of cocaine are beyond doubt. By inhibiting neuronal reuptake of excitatory neurotransmitters, dopamine, serotonin and norepinephrine, cocaine enhances synaptic concentrations of these neurotransmitters in specific brain areas; nucleus accumbens and amygdala which are referred to as the reward center of brain. During 1980s, cocaine widely replaced heroin as drug of abuse, due to its euphoric properties, wide availability and low cost. Different forms and Routes of administration of cocaine: Smoking: Crack, freebase or smokable form of cocaine, was produced and became popular drug of abuse in 1980s. Earliest reports of crack use indicate an epidemic in Bahamas from 1980. By 1985, crack gained popular ranking among drug users across America.Crack is produced by mixing 2 parts cocaine hydrochloride with one part baking soda (sodium bicarbonate). It differs from cocaine hydrochloride in being more volatile, a property that makes it better suited for inhalation administration (smoking) than cocaine hydrochloride. Smoking freebase cocaine releases methylecgonidine, an effect not achieved with insufflation or injection (described later), thereby making it a specific test marker for freebase cocaine smokers. Studies suggest that methylecgonidine is more harmful to heart, liver and lungs than other byproducts of cocaine. Inhalation leads to rapid absorption of cocaine into bloodstream via lungs, reaching brain within five seconds of ingestion. Following rush exceeds snorting in intensity but does not last long. Oral: Ancient tradition of South Americans to chew coca leaves in same manner is tobacco, is another method of cocaine consumption. Alternatively, coca leaves may be consumed like tea by mixing with liquid. Coca leaf consumers have raised a controversy over whether it should be abandoned or not. Rationale behind this controversy is that strong acid in our stomach hydrolyzes cocaine, attenuating its effects on brain; therefore, unless it is taken with an alkaline substance, such as lime, which neutralizes stomachs acid, cocaine intake should not be criminalized. Cocaine is also used as oral anesthetic, both medically and unofficially. Cocaine powder is applied to gums to numb the gingiva and teeth. Colloquial terms for this route of administration are; numbies, gummies and cocoa puffs. Another method for oral administration, commonly known as snow bomb, is to pack cocaine in rolled up paper and swallowing it. Insufflation: Colloquial terms for which are; snorting, sniffing, or blowing is believed to be most commonly employed method of cocaine ingestion in west. Cocaine is poured on a flat, hard surface and divided into fine powder before being insufflated in â€Å"bumps†, â€Å"lines†, or â€Å"rails†. Devices used as aid in insufflation are known as â€Å"tooters†. Rolled up banknotes, hollowed-out pens, cut straws, pointed ends of keys, specialized spoons, long fingernails, and (clean) tampon applicators may all be used a tooters. Injection: This achieves the greatest bioavailability, 100%, in shortest span of time, since drug is directly administered into bloodstream saving time and reduced bioavailability that occurs with drug absorption from site of drug administration into bloodstream. Resultant rush is intense and rapid. Risk of contracting blood-borne infections is greatest. â€Å"Speedball†, a mixture of cocaine with heroin used intravenously is a popular and dangerous method of cocaine ingestion. It claims credit for many deaths, including celebrities like John Belushi, Chris Farley ,Mitch Hedberg, River Phoenix and Layne Staley. ADME Pharmacokinetics: Absorption, Distribution, Metabolism and Excretion of Cocaine. Before beginning discussion about pharmacokinetics or ADME of cocaine, table below summarizes the relationship of route of administration with onset of action, time taken to achieve peak effect, duration of action and half life. (Clarke, 1986) Absorption: Absorption refers to movement of drug from site of administration into bloodstream.As with any drug, absorption of cocaine depends on various factors and varies considerably with them. Factors which influence drug absorption include; drug formulation, route of administration, lipid solubility, pH of the medium, blood supply and surface area available for absorption. As evident from tabulated figures above, cocaine differs greatly in onset of action varying between 7 seconds up to 10 minutes from one route of administration to another. This is a factor of absorption of drug which depends on route of administration. Each route is separately discussed below in greater details. (Clarke, 1986). Orally administered cocaine: Cocaine induces vasoconstriction in vessels supplying oral mucosa and resultant reduction in blood supply slows down its absorption by decreasing surface area from which drug is absorbed. Therefore when orally administered, drug is slowly absorbed into bloodstream, taking roughly 30 minutes. Absorption is also incomplete; roughly one third of administered dose is absorbed. Due to slow absorption, onset of action is also delayed and peak effect is, however, not achieved until about 50-90 minutes after administration. Effect is, however, longer lasting, roughly 60 minutes after attainment of peak effect. Another factor affecting absorption of orally administered cocaine is pH of the stomach. As previously mentioned, stomach acid hydrolyzes cocaine, resulting in inadequate and incomplete absorption. To improve absorption it is common practice to take cocaine along with an alkaline liquid to neutralize acidic pH. Insufflations: Insufflations results in coating of the mucosa covering sinuses with cocaine, from where it is absorbed. Absorption is similar to that from oral cavity, cocaine induced vasoconstriction beneath mucosa results in slow and incomplete absorption (30-60%). Efficiency of absorption increases with concentration of drug. According to a study, time taken to reach peak effect via this route of administration averages 14.6 minutes. Injection: Injected cocaine is directly administered into bloodstream eliminating need for absorption. According same study, as mentioned for insufflation, time taken to reach peak effect of cocaine through injection averaged 3.1 minutes, roughly five times less than time for insufflation. Smoking: Smoking crack delivers large quantities of the drug to the lungs, resultant absorption is rapid and effects created are comparable to intravenous administration. These effects, which are felt almost immediately after smoking, are intense and last for 5-10 minutes. According to Perez-Reyes et al, 1982, volunteers who smoked 50 mg of cocaine base in a controlled study experiment achieved rapidly elevated plasma cocaine level compared to intravenous cocaine administration. Distribution: Following absorption into bloodstream, cocaine is distributed, via blood, to all body tissues including vital organs like brain, lungs, liver, heart, kidneys and adrenals. It crosses both blood-brain and placental barrier. Being lipid soluble, it easily traverses biological membranes via simple diffusion. It is believed to accumulate in brain and adipose tissue with repeated administration, owing to its lipid nature. In an experiment, distribution and kinetics of cocaine in human body were studied using Positron Emission Topography (PET) technique with radioactively labeled (carbon-11) cocaine on 14 healthy male subjects. Rate of uptake and clearance were found to vary among organs. Following results were obtained for time, in minutes, taken by radioactively labeled cocaine to reach peak value in following organs: Lungs: 45 seconds. Heart and Kidneys: 2-3 minutes. Adrenals: 7-9 minutes. Liver: 10 minutes. Liver, which is the key site for metabolism of cocaine is where distribution is most sluggish, increasing the half-life of cocaine. The Journal of Nuclear Medicine ( 1992 ) Metabolism: As already mentioned, cocaine is primarily metabolised in liver. It is estimated to get metabolized within two hours of administration. Half-life varies between 0.7 1.5 hours (Clarke, 1986), depending on route of administration among various other factors. There are three possible routes for bio-transformation of cocaine. Ester linkages in cocaine are hydrolyzed by plasma pseudocholinesterases and hepatic enzymes, human liver carboxylesterase form 1 (hCE-1)and human liver carboxylesterase form 2 (hCE-2). Benzoyl group is eliminated to produce ecgonine methyl ester. This is the major route for metabolism of cocaine. A secondary route, suggested by Fleming et al. 1990, proposes spontaneous hydrolysis, possibly non-enzymatic, followed by demethylation to produce benzoylecgonine. N-demethylation of cocaine is a minor route which leads to formation of norcocaine. Final degradation of metabolites yields ecgonine. Principal inactive metabolites are; benzoylecgonine, ecgonine methyl ester, and ecgonine itself. Norcocaine is an active metabolite and may reveal itself in acute intoxication. Metabolism of cocaine may be influenced by a number of factors: Alcohol:When cocaine is co-administered with alcohol a compound called Cocaethylene is formed. Cocaethylene is associated with an increased risk of liver damage and premature death. Pregnancy. Liver disease. Aged men. Congenital cholinesterase deficiency. In all the aforementioned conditions, except alcohol, rate of cocaine metabolism is reduced, leading to elevated levels and duration of action of cocaine, enhancing its harmful effects of on the body. Following is a schematic representation of metabolic pathways of cocaine. According to Andrew (1997) have found that the continuous use of alcohol with cocaine produce cocaethylene which is similar in the action of cocaine but it has more blood stream concentration by three to five times than cocaine as a result of its high half life. Its much attractive to be used for abuse as a result of slower removal from the body. Different types of side effects are associated with cocaethylene like liver damage, seizure and immuno compromised functioning . Cocaethylene has more possibility for sudden death by 18 25 times than using cocaine alone . Butyrylcholinesterase (BChE) has been implicated as being important in metabolism of cocaine, even though it has limited capacity to fully hydrolyze cocaine. BChE is specially essential for cocaine detoxification. A lot of research has been done to study the effect of employing this enzyme in cocaine detoxification and in anti-cocaine medications. Cocaine are hydrolyzed by human BChE in a slow rate , however, in university of Nebraska medical center the scientist at molecular biology and biochemistry have developed a mutant (A328Y) of human butyrylcholinesterase, which promises four fold greater efficiency in accelerating cocaine metabolism. Elimination or excretion: 1-9% of cocaine is excreted unaltered in urine along with metabolites, ecgonine methyl ester, benzoylecgonine, and ecgonine. Unchanged cocaine may also be eliminated through GI tract and/or be excreted in saliva. Most of the parent drug is eliminated from plasma within 4 hours after administration but metabolites may remain detectable for up to 144 hours after administration. Elimination of cocaine via kidneys is enhanced by acidification of urine. As already mentioned, cocaine easily traverses placental barrier, and the active metabolite, norcocaine is believed to persist in amniotic fluid for up to 5 days. In lactating mothers, cocaine metabolite can be found and presets for longer time up to 36 hours after the first administration and it will be found after they excreted into maternal milk. On the other hand, it will be eliminated very fast through exhalation or vapor when it is administrated through smokes. Ambre J et.al (1988) In an experiment, the investigations of chronic cocaine oral administration effects in those healthy volunteers having a history of cocaine abuse were continued. There were sixteen daily sessions of oral cocaine administration while subjects were kept in a controlled clinical ward. In every session subjects received five equal doses of oral cocaine at one hour interval. Throughout session, the doses of cocaine were administrated by an elevating rate starting from 100 mg as an initial dose (500 mg/ day) reaching to 400 mg (2 g/day) by a rate of increase of 25 mg/ dose/ session (125 mg / session). Urine specimens were collected throughout the study while at the end of the study specimens like saliva and plasma were periodically collected during the one week withdrawal phase and during the dosing session. The analysis of cocaine and cocaine metabolite were carried out by solid phase extraction and followed by gas chromatographic mass spectrometric analysis in the SIM mode. ARE is defin ed as a method or plots used to calculate the Half-lives of urinary elimination for cocaine and cocaine metabolites which stand for ( the amount remaining to be excreted ) plots. The urinary elimination for cocaine and cocaines metabolites in the Result obtained yielded two phases. An initial elimination phase during withdrawal which was has the same elimination pattern observed after acute dosing, and a terminal phase. Results were as follows: Initial phase: Mean plasma cocaine elimination half-life: 1.5  ± 0.1 h. Mean salivary cocaine elimination half-life: 1.2  ± 0.2 h. Mean urinary cocaine elimination half-life: 4.1  ± 0.9 h. Terminal phase: Mean urinary cocaine elimination half-life: 19  ± 4.2 h. A terminal elimination phase was also observed for cocaine metabolites with half-life estimates ranging from 14.6 to 52.4 h, which greatly exceeded previous estimates from studies of acute cocaine administration. This experiment shows that with chronic use, cocaine accumulates in the body with resultant prolonged terminal elimination phase for itself and its metabolites. Like any pharmacokinetic feature of a drug, elimination may also be influenced by various factors. Since renal elimination is major route for cocaine excretion, state of renal function is essential determinant of efficiency of elimination. Patients with poor renal function are much more likely to develop toxicity than those with properly functioning kidneys. Also, as already mentioned, acidification of urine accelerates the elimination of cocaine from the body. Drummer O.H et.al ( 2001) Pharmacodynamics of cocaine: Mechanism of action. Cocaine mediates its actions through two basic mechanisms: Inhibition of re-uptake of monoamines; dopamine, nor adrenalin, and serotonin. Blockade of sodium channels. As previously stated, a major breakthrough in field of surgery was discovery of cocaine and establishment of its use as a local anesthetic. All local anesthetics achieve their effect by same mechanism, known as membrane stabilizing effect. They achieve this by blocking the voltage gated sodium channels in neuronal membranes. Figure 1.0 shows the action of cocaine on sodium channels. Nerves carry impulses in the form of action potentials. Conduction of action potential involve a wave of depolarization, followed by repolarization, to travel along the nerve fiber. Depolarization, movement of membrane potential away from resting potential, is achieved through opening of voltage gated sodium channels and consequent influx of sodium. Local anesthetics reversibly reduce the rate of depolarization and repolarization by blocking these voltage gated sodium channels and eventually, impulse conduction is completely obliterated. Since local anesthetics prevent depolarization of membranes, membrane potential stays near resting levels; this is why it is called membrane stabilizing effect. Local anesthetic drugs make the onset of neuronal blockade faster especially in rapidly firing neurons when they target open sodium channels which is known as state dependent blockade. Local anesthetic action of cocaine is pH dependant. Potency and rate of action tends to decrease with the pH. Inhibition of re-uptake of monoamines; dopamine, nor adrenalin, and serotonin. Image above, taken from web, clearly demonstrates the action of cocaine (shown as yellow block in the figure) on dopamine re-uptake. Figure on the left shows normal process of synaptic transmission from a dopaminergic nerve terminal. Dopamine is secreted by the nerve terminal into synaptic cleft and subsequently binds to its receptor on post synaptic membrane. This is followed by its re-uptake via dopamine re-uptake transporter on neuronal membrane back into nerve terminal where it is degraded by MAO (Monoamine oxidase) into monoamines. Figure on right shows similar synapse, in presence of cocaine. Cocaine binds to dopamine re-upta

Song - What views about women are expressed in this poem? Essay

Song - What views about women are expressed in this poem? John Donne: Song A) What views about women are expressed in this poem? John Donne’s poems all express very different views about women. This poem expresses a very negative view of women, in particular that nowhere ‘lives a woman true, and fair’ – a beautiful, virtuous woman is impossible to find, and even if you did, by the time that Donne had reached her, she would have adulterated two, or maybe three other men. He believes in the certainty of female immoralism ‘yet she / will be / false.’ And the almost random promiscuity too, it will be two, or maybe three men, it’s very casual. He compares women to the sirens of the sea – mermaids, in the way the seduce you, and pull you down to the depths, suffocating you. While they are not an object of sexual desire but deception, because below the waist they have they have a slimy, scaly fishy tale. He may view himself as sort of Odysseus figure, just trying to find his image of his perfect woman on some mythical Ithaca. He continues these themes of deception further in the poem, which I shall explore in the next question B) How do language and verse form contribute to meaning in this poem In the first stanza Donne uses very commanding language, four lines out of nine begin with an imperative, and this shows his commanding, intellectual persona and his attitude towards women. In the first stanza Donne presents us fantastical images of various impossibilities which contribute meaning to his opinion of woman. The first sentence is a command: "Goe and catch a falling star," and an impossible one, for how can one catch a star? The word "falling" suggests a gradual fading away of the virtuosity of... ...tions take.’ One drop in a pond will cause rippling outwards – it continues to grow. He compares the circles to spheres of the heavens, but he says ‘they are all concentrique unto thee.’ This is a great metaphor for defining love, he feels that his lover is the centre on the heavens and outshines everything, the years passing to nothing bar ‘adde to love new heate.’ His love may increase through springtime but never abates through bad times, â€Å"No winter shall abate the springs encrease.’ Donne suggests that it cannot abate, he compares his growing love as too the infiniteness of the sky and the stars, which would have been never anything less than infinite in those times. Here we can see Donne as a simplistic adolescent, when he is in love he can never see it ending, while when he is feeling bad all women are evil and he will never go out with one again.

Buffalo Soldier-Dreadlock Rasta? :: essays papers

Buffalo Soldier-Dreadlock Rasta? The Buffalo Soldier of the West and the Elimination of the Native American Race When black men first enlisted in the United States army, they were thought to be crazy. These were the men, who just a few years before, were being persecuted because of the color of their skin. Throughout time, the black man has suffered in more ways than we could imagine. The white man stole them from their homeland only for the sole purpose of making money. They were thought to be hard workers and very loyal. However, after the Civil War and the emancipation of slavery, there became some perceptions of the black man that had never been seen or heard before. Even though they were still thought to be inferior, they still gained some respect on the part of the white community. In 1864, the President of the United States, Mr. Abraham Lincoln wrote a statement concerning the black troops enlisted in the U.S army. With the sympathy of the president, this is what was written: The black soldiers in the Civil war had so heroically vindicated their manhood on the battlefield where, in assisting to save the life of the republic, they have demonstrated in blood their right to the ballot†¦." (Cashin and others 1969 p.i) This message was the forthcoming of a new perception of the black man. With the help of President Lincoln, the black man felt that they were on their way to freedom and equality. However, after the assassination of the "Great Emancipator" the black man’s hopes and dreams seemed to fade faster than they were built up. With the signing of the Emancipation Proclamation, President Lincoln had given the black man one of America’s highest standards for being considered free. He gave them the right to vote. However, since the assassination, the southern black man could not vote because of the stipulations that the white southerners put on the voting system. Therefore, the black man could only hold on to the last shred of freedom that he was given the right to have. Because of their gallant efforts put forth in the Civil War, the black man was still allowed to serve in the United States army. In 1866 a bill was passed by Congress to allow the formation of an all black regiment. In all there would be several different regiments comprised of only black soldiers. The regiments were formed by the black enlistees and usually the duties were carried out by a white officer.
