The End of Euro Disneys as a White-knuckle Ride Essay

The End of Euro Disneys as a White-knuckle Ride - Essay Example It is not expected for growth in the European sector to be experienced until 2010 or 2011, which will require Disneyland Europe to find innovative methods to draw higher crowd volumes and ensure profit success. Additionally, rising commodity prices which will be felt in 2009 will seriously erode the potential for profitability in this year, with the business forced to cut costs where necessary and appropriate. One publicity expert identifies that theme park industries are highly competitive and strategic success involves the volume of guests which pass through the entrance turnstile every day (Kohl, 2000: 48). Further, the author identifies that attendance is so widely important that many executive leaders have hourly tourist counts pumped into their mobile devices for the sake of tracking customer numbers (Kohl). This is especially true at Disneyland Europe which relies on customer volumes to generate annual profit. Getting higher sales volumes, however, in the midst of the current credit crunch requires understanding competitive behaviors whilst redesigning Disneyland Europe with a new, modernized logo to attract the contemporary consumer. Readjustments to marketing will be the proverbial saving grace for Disneyland Europe in the next five years. In 2009, Disneyland Europe must make a stronger effort to understand its customers. Since over 40 percent of all customers are French, repositioning the EuroDisney brand to focus on French lifestyle can ensure a higher revenue stream during the current economic crisis. This will be increasingly difficult beyond 2008 and will require research into existing consumer behaviors in French markets. Snyder (2002) offers that the French tend to link Disneyland Europe with American culture, giving them a negative perception of â€Å"cultural imperialism† in which the theme park is  attempting to force American lifestyle into a proud, French culture. Negative cultural perceptions must be eliminated whenever possible in the new marketing model.  

Nortel Case Report Essay Example for Free

Nortel Case Report Essay The company also used to be affiliated with ATamp;T/Western Electric until Western was forced to sell its stake in 1949. In 1976, the company changed its name from Northern Electric to Northern Telecom Limited, and shifted its concentration on digital technology. In 1977, Nortel introduced its DMS line of digital central office telephone switches. Nortel ended its long relationship with ATamp;T in 1984, a year after deregulation named. Bell Canada Enterprises the parent company to Northern Telecom. In 1998, the company acquired Bay Networks and changed its name to Nortel Networks. In the late 90’s, Nortel’s sales of fiber optic network gear was predicted to help their sales, but the market became saturated very quickly. At the height of Nortel’s first 100 years the company amassed for more than a third of the total valuation of all companies listed on the Toronto Stock Exchange (TSX), but once the Internet bubble passed, the company fell into ethical debacle. Nortel Networks Corporation, or formally known as Northern Telecom Limited was one of the largest telecommunications equipment companies in the world prior to its filing for bankruptcy protection on January 14th, 2009. During times of functionality, they specialized in multinational telecommunications equipment manufacturing. The company is based in Canada out of Mississiauga, Ontario, Canada. Their biggest rival always was Global System Mobile (GSM). Through the early 1990s, the company invested heavily in Code Division Multiple Access (CDMA) in attempt to grow in European and Asian markets. This did not pan out so well as Nortel’s losses amounted to $27. 3 billion by 2001—causing them to lay off two-thirds of the workforce. From 2000 through 2003 there was a period of fiscal irresponsibility resulting from the work of the company’s administrators. Initially in 2000, they falsified their fourth-quarter earnings by $1 billion to meet market expectations and selectively reversing certain revenue entries. In 2002, administrators discovered $300 million in excess reserves being carried over and swept it under the rug for future benefit in addition to establishing another $151 million in unnecessary reserves. In 2003, administrators directed the release of at least $490 million of excess reserves to boost earning, fabricate profits, and pay bonuses. Losses turned to profits during this year thanks to the shifty methods taking place. Later in that year, administrators mislead investors as to why Nortel was conducting a purportedly â€Å"comprehensive review† of its assets—attributed by restatement $948 million in liabilities. They said restatement was caused solely by internal control mistakes instead of the truth that there was intentional improper handling of reserves which needed to remain hidden. 2 On October 23rd, 2003, the company announced that Nortel would restate its financials for fiscal years 2000, 2001, and 2002. Shortly after this restatement, the major players of Nortel’s administration that were responsible for all of this were exposed through an independent investigation. In March 2004, The CFO and controller were suspended, in addition to the announcement of further restatements and revisions; they were terminated a month later in April 2004. A restatement in early 2005 showed approximately $3. 4 billion in misstated revenues and another $746 in liabilities. In late 2005, Nortel admitted that restatements were the result of management fraud—beginning the downturn of their stock. The company ended up restating financials four times over four years, replacing senior management, and instituting a comprehensives remediation program designed to ensure proper accounting and reporting practices. Eventually on October 15th, 2007, Nortel agreed to settle by paying a $35 million civil penalty and admitting to violations of the antifraud, reporting, books and records, and internal control provisions of the federal securities laws. 2 On June 25th, 2009, Nortel’s price dropped to 18. 5 cents a share down from a high of $124. 0 in 2000. The company decided that month that they would discontinue operations and sell off all of its business units. Nortel’s CDMA wireless business and LTE access technology were sold to Ericsson, and Avaya purchased Nortels Enterprise business unit. Major Players in the Scandal: The major players in this scandal were the four members of the senior management: CEO Frank Dunn, CFO Douglas Beatty, controller Michael Gollogly, and ass istant controller Maryanne Pahapill. CEO Frank Dunn, who is also a certified management accountant. Dunn was mainly involved in the improper use of reserves from 2000 to 2003. CFO Douglas Beatty, controller Michael Gollogly, and assistant controller Maryanne Pahapill were also involved in this management fraud. 2 The Royal Canadian Mounted Police in Toronto arrested ex-CEO Frank Dunn, ex-CFO Douglas Beatty, and former corporate controller Michael Gollogly on seven counts of fraud. Including charges â€Å"fraud affecting public market; falsification of books and documents; false prospectus, pertaining to allegations of criminal activity within Nortel Networks during 2002 and 2003. Magnitude of the financial issue: Nortel at its peak was one of the best companies that Canada had ever seen. Just like ENRON and other financial frauds at the time, Nortel appeared to be a shining example of success in the corporate world. Again like ENRON, Nortel grew through a strategy of aggressive expansion and purchasing of smaller companies in order to create a massive conglomerate. During the good times Nortel was the largest technology company and the most valuable company in Canada. Nortel accounted for over one third of the entire aluation of the Toronto Stock Exchange. The Toronto Stock Exchange is the Canadian equivalent of the New York Stock Exchange and holds the most influential stock market in Canada. Nortel employed about 95,000 employees worldwide. About 26,000 of those workers based in Canada alone. Nortel at one point had a market capitalization of almost C$400 billion. Nortel had set up pensions and healthcare protection for its employees. All of these were lost to either the restructuring under Frank Dunne which left about 60,000 employees without jobs or the bankruptcy that followed in 2009. Canadian government officials and regulators identified how destructive a full failure of Nortel would be on the Canadian economy. The Canadian government through the Export Development Canada project tried to lend money to the falling giant. However the Canadian government could not cover all of Nortel’s debt obligations. Nortel owed about $107 million and the EDC (Export Development Canada) could only supply about $30 million in short term loans. This $107 million interest payment accounted for about 4% of Nortel’s cash and put the company into bankruptcy. The world financial crisis of 2008 had put too much strain on Nortel and they were forced to begin liquidation. Public auditor: The auditors involved with this case were Deloitte and Touche. In documents from the fraud case, which is still being heard by the Royal court in Canada, Deloitte claims that they were not given proper documentation by Nortel. Deloitte claims that they did not have pertinent information which should have been provided by administrators at Nortel. Deloitte raised concerns to the audit board of Nortel in 2003 when Nortel turned a profit after Frank Dunne’s restructuring of the company. Deloitte raised awareness of potential fraud and did their duty in that respect. However further investigation conducted has implicated Deloitte in the financial reporting irregularities in Nortel which some have claimed dates back to the time of CEO Roth who held office before Dunne. Information coming out of the case states that even if transactions were deemed suspicious, they still signed off on the verity of the financial reports. Frank Dunne and some of his officers are now charged with fraud by both the SEC and the OSC which regulate the American and Canadian markets respectively. The case is currently still under review in the Royal court of Canada and civil charges have been brought in the United States. Fraud Triangle Nortel had experienced tremendous growth throughout the 1990s, allowing it to expand operations worldwide. Nortel’s expansion came during the telecommunication and technology bubble of the 1990s that inflated stock prices of companies in those sectors. Frank Dunn had taken over for the previous CEO, John Roth, in November 2001 during the telecommunication bubble bust. Dunn felt pressured to maintain the high stock price because it accounted for over one third of Nortel’s value2. Nortel management was also incentivized to post profits that produced executive bonuses with over $7. 8million going to Dunn alone. The primary members of the Nortel fraud were able to commit the fraud because, as executive officers and controllers, they were able to go around the internal controls of the company. That allowed them to implement many accounting practices that did not comply with GAAP. Nortel management’s rationalization for these fraudulent practices must have been that they needed to maintain the high stock price in order for the company to continue operating. Moral Breach and Ethical Issues As a publicly traded company, Nortel had the responsibility of fairly reporting the company’s true financial data to stockholders and potential investors. Dunn, Beatty, Gollogly and Pahapill breached this responsibility by establishing earnings management accounting strategies to manipulate Nortel’s revenues. Nortel management also actively sought to inflate earnings to trigger very large bonuses for key members of management. Perhaps, if these incentives did not exist then there would be less motivation to commit the fraud. Finally, Nortel’s auditor for over a century, Deloitte and Touche, has come under scrutiny by the defense lawyers in Dunn, Gollogly and Beatty’s civil trial in Canada this year. The defense claims that Deloitte approved of all major accounting adjustments that Dunn and his team had engaged in. Summary of Legal Actions On April 28th, 2004, Dunn and his fraud partners were fired for financial mismanagement2. On March 12th, 2007 the SEC filed civil charges against Dunn, Beatty, Gollogly and Pahapill for repeatedly engaging in accounting fraud to bridge gaps between Nortel’s true performance, its internal targets, and market expectations. Dunn and Beatty were charged with violating the officer certification agreement that was established by the Sarbanes-Oxley Act. Nortel settled with SEC on October 15, 2007 by consenting to be prescribed from violating the antifraud, reporting, books and records, and internal control provisions of the federal securities laws. Nortel paid $35million to the SEC, and $1million to the Ontario Securities Commission to establish a Fair Fund for affected shareholders. Finally, Canadian authorities arrested and charge Dunn, Beatty and Gollogly with seven counts of fraud. Their trial began on January 16th, 2012. Current Status: Nortel, once known as the largest telecommunications manufacturer in the world, filed for bankruptcy in 2009. Now three years later, the period of bankruptcy continues as the company discloses their every operating report highlighting each cash receipt and disbursement. When Nortel went bankrupt, executives believed that selling all business assets would be the best and easiest way to fight debt. Recently, Nortel has netted $7. 7 billion from selling its patents and businesses. As stated on their website, â€Å"Nortel remains focused on maximizing value for its stakeholders, including the sale of its remaining assets, resolution of claims, the wind-down of its global operations and entities, resolution of allocation matters with respect to the sale proceeds, and other significant restructuring activities toward the conclusion of the creditor protection proceedings. † The case for Nortel executives Dunn (ex CEO), Beatty (ex CFO) and Gollogy (ex controller), who were charged with fraud for affecting the public market and falsifying books and documents to earn larger bonuses, is still in trial. In February, a former Vice President of Nortel testified in court against executives stating that they had asked him to use questionable accounting methods to manipulate the company’s earnings. Although those who committed the crime have been charged, thousands of employees will still be left without pension plans and jobs. Nortel has spent over $20 million on retirement package these past two year, but unfortunately the company will stop the pension plan and disability program payments as it continues to sell away its businesses. By the end of 2011, Nortel was split into regional entities – Nortel Networks Limited in Canada and Nortel Networks Inc in the United States, causing disagreements over how to split $7. 5 billion that was earned by selling many assets and patents other corporations such as Apple and Microsoft Corp. The following charts, graphs and financial statements analyze Nortel’s current status. Case Study Questions and Solutions: 1. Dunn is a certified management accountant. Based on the facts of the case, which provisions of the IMA’s Statement of Ethical Professional Practice that was discussed in chapter 1 have been violated? Dunn violates many of the provisions of the IMA’s statement of Ethical Professional Practice they are as follows: 1. Perform professional duties in accordance with law, regulations and technical standards. 2. Provide decision information that is accurate, clear, concise and timely 3. Retain from engaging in any conduct that would prejudice carrying out any duties ethically. 4. Abstain from engaging in or supporting any activity that might discredit the profession. 5. Communicate information fairly and objectively. 6. Disclose all relevant information, that could reasonably be expected to influence an intended users understanding of the reports analyses or recommendations. 7. Disclose delays or deficiencies in information timeliness processing or internal controls in conformance with organization policy and/or applicable law. He violated these by selective reversal of revenue entries in 2000. Followed by concealing the reserves in 2002, which violated GAAP, and then avoided posting a profit so the company wouldn’t have to pay out bonuses. In 2003 Dunn released the reserves to falsely report a profit, which allowed them to eports a profit a quarter earlier than expected, and to pay out more bonuses to senior management. Also in 2003 he misled the investors about why Nortel had restated its financials in order to avoid uncovering the unethical management techniques him and his team had been using. All of these actions take away Dunn’s integrity and credibility in the field of manageria l accounting, which are two of the standards the IMA sets out. Dunn failed to meet his professional code of conduct and his company suffered because of it. 2. What are the responsibilities of an auditor to detect fraud? How were those responsibilities compromised by the actions of Nortel’s management? It is the auditors responsibility to report fraud if they find it, however in this case the actions of Nortel’s management made it difficult for the auditors to do their job. The false financial statements and hiding of money veiled the problems of the company from the auditors. Once there was a hint of the fraud the auditors found it and perused the trail, taking the ethical route and also following the code of conduct. It was their investigation that brought down the fraudulent executives and forced the company to restate its financials properly. This would eventually lead to the failure of Nortel. Nortel made materially false and misleading statements and omissions in connection with the quarterly reviews and materially misstated annual audits of financial statements. This caused the auditors to not be able to properly do their job, and review the statements. 3. Describe the incentives that created pressure on Nortel to manage earnings. Considering the role of Nortel’s management in this regard, discuss whether it met its corporate governance obligations as discussed in previous chapters. The incentives that drove Nortel to manage its earning where greed of the management team, the pressure to deliver bonuses, the pressure to survive an economic downturn, and the pressure to make the company seem like a good investment to both current and potential investors. In an economic climate of intense competition and corporate greed the management at Nortel fell victim to their vices and allowed the pressure to perform to overwhelm their priorities. This caused them to put their own greed and personal ambition before the well being of the company. Nortel did not meet its corporate governance obligations. It did not follow any internal rules of how to run the business. It ignored any corporate ethics they might have. It lied to stakeholders several times by misstating the financials. They did not follow the professional code of conduct of their careers and also did not follow industry standards. They broke the law. No one inside the company caught the fraud therefore their internal controls where not effective. Each of these immoral acts is a case where corporate governance has failed. 4. The final quote in the case characterizes Nortel’s failure as â€Å"just another casualty of capitalism. Do you agree with this statement? Why or why not? How would you characterize the cause of the failure at Nortel? I would argue that Nortel is not just another casualty of capitalism. Nortel did not function in a system of free market capitalism where the government had absolutely no regulation and let the markets function however they wanted. The capitalism system of North America is more of a mixed economy, which combines public and private ownership of companies, and also provides government regulation and intervention to prevent and deal with fraud. Even in a free market the system is meant to come to an equal balance of supply and demand, which cannot be reached if there is fraud involved since the supply has been inaccurately disclosed by the senior management at Nortel. I would characterize this failure as one of humanity. It was not the economic system that allowed this fraud to take place, but the greed of the people and a social environment that ties success so strongly to wealth. It was the social pressure and the effect of human nature that led to Nortel’s demise. . The case discusses how Nortel’s managers prioritized themselves over the shareholders, which, in part, lead to the company’s failure. What should be a company’s first priority? A company’s first priority should be following their code of ethics. The second priority should be the shareholders, followed by the management and other employees. This hierarchy ensures that all the business that is done with be both moral and legal , meaning there is no room to commit fraud and damage the company. In this way you are putting the shareholders first, because by providing a stable and healthy company the shareholders will see an investment that will be able to reach its highest potential. 6. Was Nortel’s settlement a fair penalty? Should the SEC have imposed harsher or more lenient sanctions? Should these sanctions have been on the managers, on Nortel as a whole, or both? A fair settlement would offer compensation to all those who were hurt by this fraud. Groups that may have been hurt could be shareholders, employees and customers. Deciding what is a fair compensation is a little more difficult, however as much of what these people lost as possible should be returned to them. As for the managers who created the problems and took part in the fraud should face a sentence of termination from their company, loss of license (if applicable) and jail time. The company and the individual managers have both failed stakeholders and should both be held accountable. In the case of Nortel specifically the stockholder settlement goes with these guidelines, as for the managers their trial is still ongoing and therefore no sentenced has been given to them yet.

Handling Stress Essay -- essays research papers

Handling Stress This essay is about handling the stress of University studies. We will be looking into many ideas and different people ¹s views on how to handle stress. I will also be giving my own opinions on how I think stress can be controlled or relieved. The first thing we must do is ask ourselves one very important question,  ³what is stress ²? WHAT IS STRESS? According to an Australian born physician, Hans Selye (1979), stress is the nonspecific response of the body to any demand made upon it. The body responds in many ways. One is to the loss of blood and the other is to the lack of sleep. Both of these are nonspecific responses, however all demands made on the body evoke generalised, nonspecific responses. For example, they all unable you to concentrate as would normally be expected, they activate one ¹s sympathetic nervous system, and they also increase the amount of the hormone epinephrine that is being released into your body. When people say they ¹ve been under going alot of stress they are usually referring to a couple of unpleasant experiences.

The Qualities of a Superior Special Educator

The Qualities of a Superior Special Educator Special education is a field that will continue to need qualified candidates for at least the next decade. What makes the difference between an adequate and a great special educator?   Special Educators Are Highly Intelligent People often make the mistake of thinking that because children with disabilities are often cognitively disabled, that they dont need smart teachers. Incorrect. The era of babysitting is over. The demands on special educators intellectually are greater than on those who teach a single subject. Special educators need to: Know the general education well enough to adapt it to the ability of their students. In situations where they are co-teaching in inclusive settings, they need to understand how to make curricular information and skills (as in math and reading) accessible to their students with disabilities.Assess students both formally and informally, understanding their strengths as well as their needs. You also assess and understand your students strengths and weaknesses in terms of learning style: do they learn visually or auditorily? Do they need to move (kinetics) or are they easily distracted?Keep an open mind. Part of intelligence is natural curiosity. Great special educators always have their eyes open for new data driven strategies, materials and resources they can use to help their students succeed. This does not mean that special educators may not be disabled themselves: a person with dyslexia who has successfully completed the required college program for special education understand not only what their students need to learn, but have also built a strong repertoire of strategies to overcome the problems they have with text, or math, or long term memory. Special Educators Like Children You need to know if you really like children if you are going to teach special education. Seems like that should be assumed, but dont. There are people who thought they would like to teach and then found out that they did not like the messiness of children. You especially need to like boys, since boys represent 80 percent of all students with autism and more than half of children with other disabilities. Children often are dirty, they may smell bad at times, and they are not all cute. Be sure you like children in reality and not just in the abstract. Special Educators Are Anthropologists Temple Grandin, well-known for being both autistic and an articulate interpreter of autism (Thinking in Pictures, 2006) described her dealings with the typical world as being An Anthropologist on Mars. Its also an apt description of a great teacher of children, especially children with an Autism Spectrum Disorder. An anthropologist studies the culture and communications of specific cultural groups. A great special educator also observes his or her students closely to understand them, both in order to address their needs and to use their strengths as well as their needs to design instruction. An anthropologist does not impose his or her prejudices on the subjects or the society he or she is studying. The same is true of a great special educator. A great special educator pays attention to what motivates his or her students and doesnt judge them when they dont conform to their expectations. Like children to be polite? Assume they have never been taught, rather than they are being rude. Children with disabilities have people judging them all day long. A superior special educator withholds judgment. Special Educators Create Safe Places. If you have a self-contained classroom or a resource room, you need to be sure you create a place where calm and order reign. It is not a matter of being loud enough to get their attention. It is actually counterproductive for most children with disabilities, especially students on the autism spectrum. Instead, special educators need to: Establish Routines: Creating structured routines is invaluable to having a quiet, orderly classroom. Routines dont restrict students, they create the framework that helps students succeed.Create Positive Behavior Support: A great teacher thinks ahead, and by putting positive behavior support in place, avoids all of the negatives that come with a reactive approach to behavior management. Special Educators Manage Themselves If you have a temper, like to have things your way, or otherwise take care of number one first, you are probably not a good candidate for teaching, let alone teaching special education children. You can be well paid and enjoy what you do in special education, but nobody promised you a rose garden. Keeping your cool in the face of behavioral challenges or difficult parents is critical for your success. Getting along with and supervising a classroom aide also require that you know what you need to succeed.

Indigenous Religions Essays

Indigenous Religions Essays Indigenous Religions Essay Indigenous Religions Essay In chapter 2, the textbook author uses various terms for â€Å"indigenous religions†:  Ã‚  Ã‚  traditional, aboriginal, indigenous, tribal, nonliterate, primal, native, oral, and basic. Select four or five of these terms and discuss why you believe each of those terms is applicable to the religions covered in this chapter. â€Å"Native†. The word native relates well with the religions in this chapter because many of these religions are native to the place they come from. For instance the indigenous religion in Hawaii host a goddess of fire, Pele, whom is native to just that religion. â€Å"Oral†. The word oral relates to the indigenous religions in this chapter because that is how most of these religions were spread. Very little of these religions had writing systems to pass on their religions from one to another, so instead they used their words, artwork, and sacred artifacts to spread their religion. â€Å"Tribal†. The word tribal relates to indigenous religions in this chapter because many of the religions discussed were the religions of the different tribes. The indigenous religions fell in line with the life of tribes with creating sacrifices in order for a tribe to succeed in battle or with health. â€Å"Primal†. The word primal relates well because compared to the religions of today’s time these religions seem primitive. They either have barbaric executions or puzzling celebrations with odd mask which all seems primitive. Why do so many indigenous religions have such a reverence for nature? Many of the indigenous religions have a huge reference to nature because depending on how nature treated the people part of the religions directly related to whether they survived or not. So as a way of thanking nature for keeping them prosperous they showed their appreciation in sacrifices, celebrations, and thought of nature as godlike. Discuss the state of indigenous religions today. Indigenous religions today are way less abundant if not extinct. Many of the indigenous religions were the building blocks for the bigger religions of today, so in a sense they are still floating around just living through other religions. Most of them died with the extinction of the tribes themselves as well. What is animism? The belief that every living and inanimate objects in the universe have a spirit or soul. In general, what is the relationship between the human and animal worlds among indigenous religions? In general they go hand in hand with each other. In most of the indigenous religion when killing and animal for meat or killing a tree for shelter they do it respectfully as possible in reference to their souls. How do indigenous religions, in general, select their â€Å"sacred spaces†? Indigenous religions select a great mountain, a volcano, a valley, a lake, a forest, a single large tree, or some other striking natural site. How are ancestors viewed in most indigenous religions? Ancestors in ‘most’ indigenous religions have almost god-like respect for them. They are treated quite well out of love for them and their power they are thought to have. What â€Å"big events† in life are usually marked by ceremonies in indigenous religions? In indigenous religions rites of passage are marked by ceremonies; Child birth and crossing over into adulthood are examples. What is a taboo? What are some examples of taboos in our modern culture, and are they religious or cultural in nature? A taboo is a rule that forbids specific behavior with regard to certain objects, people, animals, days, or phases of life. A taboo in our modern culture would be something like picking your nose in public. By nature taboos are more cultural than religious. To me they are a combination of the two; culture and religion. What is a shaman, and what role does the shaman play in indigenous religions? A shaman is a person who can contact the spirit realm, receive visions of it, and transmit messages from it, often to help or heal others. The shaman acts as an intermediary between the visible, ordinary world and the spirit world.

How successful was Louis XVIII in establishing stability in France during his reign Essay Example

How successful was Louis XVIII in establishing stability in France during his reign Essay Example How successful was Louis XVIII in establishing stability in France during his reign Paper How successful was Louis XVIII in establishing stability in France during his reign Paper Essay Topic: History Louis XVIII came to the throne after the warfare and economic dislocation of the Napoleonic years. He was king of France from 1814 until his death in 1824. To decide whether he was successful or not, first the word success has to be defined. Success is, in terms of being king, keeping the country running well (socially, economically and politically). I feel that during Louiss time as king, many important changes and incidents happened for the French people which he handled amicably and he was an overall success. His reign can be split into different periods, the liberal era and the ultra era. Upon coming to the thrown in 1814, Louis XVIII faced several problems. Since the demise of his brother, Louis XVI, France had been characterized by warfare and economic dislocation (Randell). Napoleon had left a war-weary population under heavy taxes to bankroll his doomed foreign conquests that had resulted in France being on the periphery of international politics. How ever Napoleon was successful in setting up an effective civil service bereft of corruption and the French people, particularly the Bourgeoisie, had gained from the French Revolution and feared the new Bourbon monarch would revert to the ways of the Ancien Regime. Thus, many would not have been heartbroken had Louis XVIII faltered. Many of the royalists supported him for what he stood for, not for who he was. They yearned for the political stability associated with a legitimate monarchy and were not pre-occupied with who filled the role. They wanted to gain a sense of security and permanence that had been missing in the recent past (Randell). They too were wary of Louis intentions. One of Louis first and arguably wisest decisions was to introduce the Charter by which he would rule. It acted as a stabiliser as the first few months of his rule was crucial in gaining the silent trust, if not the public support, of the French people, especially the pays legal, those involved in politics. It was significant as it showed Louis accepted the gains the people had made as a result of the Revolution. The Charter guaranteed equality before the law for every Frenchman, proportional taxation, press freedom and the up keeping of a meritocracy in the civil service and military. This disproves the opinion of many that whilst in exile the Bourbons learnt nothing and forgot nothing. There existed a faction within the Royalists known as the Ultras. These were considered more royalist than the king himself. Many were i migri s and wanted an Autocracy, as in the days of the Ancien Regime. They possessed political clout in abundance and Louis was successful in keeping them in check, however they gain importance in the later years. The downfall of many Kings is in the Ministers they appoint. Louis XVIII shrewdly appointed competent moderate ministers in the face of an Ultra dominated Chamber, the most prominent Ellie Decazes. Under his guidance France experienced an economic boom which brought prosperity to the people and fostered stability in the country. Napoleon escaped from Elbe in 1815 and seized power in a period knows as the 100 days. Due to the support the French people gave him the allies punished France by making them pay war indemnities and stationing their troops in France until this was paid off. The presence of foreign troops in France angered the French people but the economic boom allowed for France to pay off the war indemnity by 1817 and the allies duly removed their troops. Louis was once again successful. Louis XVIII was successful in resisting the temptation to involve the Church in state affairs, especially education. However they were one of his main supporters as the Church was the source of news and information for all peasants, thus it was an effective tool in maintaining support. The King did make minor errors however. He restored the Bourbon flag as the national flag. After the 2nd restoration the King was seen as a puppet of the allies and the French people felt he turned a blind eye to the white terror, where Royal sympathisers persecuted those who had supported Napoleon upon his return. Was Louis XVIII successful as King of France? At home and abroad? Louis XVIII was king of France between 1815 and 1824. To decide whether he was successful or not, first the word success has to be defined. Success is, in terms of being king, keeping the country running well (socially, economically and politically) and making sure that the French people have the best conditions for life possible, this may mean that they are not completely content. During Louiss time as king, many important changes and incidents happened for the French people, many of which I feel Louis handled with great shrewdness and intelligence; therefore I feel that as king of France, Louis XVIII was a success. This is because of his attitudes politically, introducing the charter and therefore realizing that France could no longer return to the ancien regime; because he chose ministers who had moderate elements, so France could attempt to recover after war; and because he did his best to avoid any extremes in policy. On the other hand, there is evidence that Louis could have been described as a poor king, with, even though he was not directly involved, the white terror and the Ultra government, which had power But in 1820 the situation was becoming increasingly chaotic and Decazes resigned. Meanwhile Louiss age (he was 65 at this point) was telling on him. It was getting harder for him to fend off the Ultras. Increasingly power even within his own cabinet was passing out of his handsin particular when he was forced to accept Villi le (1822-1824) as prime minister and to take on board his brother as a member of the cabinet.

Voltaire's Candide Essay Example | Topics and Well Written Essays - 1250 words

Voltaire's Candide - Essay Example Female characters have been shown inhumanly beaten, molested, raped, enslaved and sold again and again from one hand to another. Although, Voltaire was popular for having vocally favored and propagated the equal rights of women, yet, this feeling is not noticeably perceptible in Candide, particularly taking into consideration the reality that the major female characters are negatively portrayed as prostitutes, lustful women that marry for wealth, infected disease-carriers, and most prominently victims. In general, while Voltaire’s effort was definitely seditious and critical of society, any prospective revolutionary value lies only within the sagacity that it uncovered weaknesses in the prevailing communal configuration. Female Characters; Evolution of Sufferings Throughout the novella, its female characters have endured numerous challenges and undergone extreme sufferings, which have made it tremendously difficult for Candide to continue to believe Pangloss's philosophy. Huma ns are either destined to live in misery or in the lethargy of boredom. This is ridiculing and is brought about by the famous saying, "All is for the best in the best of all possible worlds". And in no way are we meant to be receiving Pangloss as a believable character; like Candide he is over exaggerated and distorted to the extent that his philosophy is almost inseparable from his character. One finds that Pangloss is a recurring nightmare of Candide in the way that he constantly returns from moments of almost certain peril alive, and therefore re-ignites the morsels of optimism that Candide still contains. Pangloss maintains that this is the best of all possible worlds, when really they are living in a cave, cut off from the suffering that still rages in the outside world. The Writer’s Purpose of Specific Depiction of Female Characters One must assume that his main purpose throughout the novella is that he provides a hole through which Voltaire can attack the optimists, bu t underlyingly to keep the story alive in the way that Candide still maintains faith and optimism that all will turn out well in the end. The significance of the Eldorado episode is to provide a frame of reference from which to compare Europe. Voltaire uses Eldorado rhetorically to contrast vices of the real world. What he is really doing is enforcing the fact that Europe is full of evil, sarcastically saying, "If you hadn’t noticed yet this is how bad Europe is," compared with somewhere in South America. But the Eldorado episode brings Candide riches, and this is a chance for Voltaire to put Candide up on a pedestal and then bring him right down again, and lower. Candide loses all his money and realizes that it just makes him a target for all sorts of swindlers, like the Vanderdendur and the Surinamese officers who try and get as much money from Candide as possible. Eldoardo is Voltaire’s paradise, his ideal world, it is void of religion and rules, it is educational, and practical, and the people there are friendly. His financial injury inspires more pessimism in him than violence ever did. This crushing of Candide through the removal of his riches lets Voltaire really point out the power of greed in man and he thoroughly ridicules the irrationality of human priorities. But one must also understand how Eldorado shows how insignificant and valueless something can be if there it exists in large quantities. So one would argue that the

Health Status in the United States and Contemporary Models of Health Essay

Health Status in the United States and Contemporary Models of Health Care - Essay Example Usually older women are more likely to develop heart disease compared to younger women, though the condition can occur in all age groups (Medline Plus, 2011). Coronary artery disease is a condition that affects the arteries that supply the heart and is caused by plaque build up in the inner walls of the coronary arteries. These plaques are made of fat, cholesterol, minerals such as calcium and other substances. Several serious heart problems arise as a result of coronary artery disease including myocardial infarction (heart attack). heart failures, cardiac arrhythmias, cardiac arrest, etc. The plaques in the coronary artery wall can narrow the lumen through which the blood flows to the cardiac muscles resulting in angina (Chest discomfort). Besides, in some instances, the plaques disintegrate causing the dislodgement of blood clots, which may in turn blocks the flow of blood to various parts of the heart (National Heart, Lung and Blood Institute, 2009). Professional practice model (PPM) is a system of practice that consists of certain structures, processes, and values, which can enable the nurse to have greater control over the delivery of nursing care in the appropriate environment for the patient. It has 5 subsets including relationships, values, delivery model, management approach and a mean of compensating and rewarding. Values include provision of high-quality healthcare, nursing responsibility, professional development and greater autonomy. In the professional relationships, greater teamwork, partnership and collaboration should be developed. In the delivery model, the decision-making should be decentralised. In order to support professional development as well as organisation growth, an appropriate compensation and reward system should be programmed (Hoffart, 1996). The professional practice model is ideal for nursing practice meant for women with heart disease. It is ideal as it gives greater

Assignment on Teaching and learning practice Essay

Assignment on Teaching and learning practice - Essay Example Boud and Hawke (2003) underlines that it is more important to make the emphasis on the assessment of outcomes and immediate competence, focuses learners’ attention on the present task and how they might address it, that is, in a way that will satisfy assessors (cited Chappell, 2003). Professional judgment is perhaps the most far-reaching and complex parameter of all. In order to check out the performance of a student, a teacher needs to understand precisely how decisions are made. Every educator and teacher should be responsible for his professional judgment she/he makes concerning students performance and their level of personal development. In this case, professional judgment is a very important activity which helps a teacher to assess a student and determine competency of a student. Professional judgment in teaching is a complex activity which requires careful analysis and evaluation of student’s achievements. The main problem is that it is impossible to teach educators how to make the right judgment in all the cases they are faced with, because every student is a unique individuality and personally influenced by social factors. For this reason, professional teachers learn how to make professional judgments on the job. Boud & Hawke create a concept â⠂¬Å"learning-how-to-learn† They explain that â€Å"currently in an outcomes-based framework, this capacity is not developed. Instead, the emphasis on the assessment of outcomes and immediate competence, focuses learners’ attention on the present task and how they might address it, that is, in a way that will satisfy assessors† (Chappell 2003). On the other hand, in order to improve their professional judgments, the educators record their comments which may include an evaluation of what they have done and/or what they are working towards. Gradually the comments become more in depth in some years of teaching practice and young teachers are able to make detailed and perceptive professional

Obama and National Security (NASA) - Essay Example Nonetheless, this paper focuses on discussing effects of changes in security and their effects on American citizens. Some of the changes that have occurred in NASA include lying off thousands of employees, thereby resulting to loss of pertinent skills and experience. Moreover, some of these changes have led to difficulty in reconstructing complex and reliable space system that can lead to increased effectiveness for security systems (Dinerman, 1). Therefore, it is evident that these changes are leading to deterioration of state security, which increases the vulnerabilities of the citizens. In this case, NASA has to be maintained for it to continue making relevant contribution on the American global power. Apparently, this agency is likely to succumb to confusion and lack of comprehensible directive that can assist in facilitating America security. In that case, Americans are likely to experience a future with increased vulnerability due to threats of terrorism. In conclusion, this paper has offered an overview of the function taken by NASA in facilitating security of Americans and effects of chang es occurring within this agency such as increased vulnerability of American citizens.

Healcare policy Assignment Example | Topics and Well Written Essays - 250 words

Healcare policy - Assignment Example However, this law has been applauded for reducing cost of healthcare as it is anticipated by research conducted by different scientists (Hertel, 2011). The implementation of the law will be affect the access to healthcare in the US since it will make healthcare accessible to many people who had no access before due to cost. However, the law will lead to detriment to quality of healthcare offered to Americans since little resources will cater for a huge number of patients (Hertel, 2011). The increased number of patients seeking healthcare will lead to increased numbers of healthcare practitioners compromising nursing standards. This will create a problem for oversight bodies in maintaining quality healthcare practices (Gray, 2011). Every American has a right to access quality healthcare and this law gives an opportunity to all Americans to access quality healthcare. In my own opinion, I think there should be a law that looks into the welfare of mental patients and a law should be created to provide mandatory healthcare to these patients. A policy should be implemented to create nursing standards and practices that cater for mental p atients under a universal healthcare

Halfway House Programs and the Community Essay Example for Free

Halfway House Programs and the Community Essay The use of halfway houses as a starting point for those who were once in prison is a great idea and can be beneficial to not only the individuals who are having to adjust to life outside of prison but also to the community around them. These homes help to stabilize the individual, help them to be able to adjust to life in society again and help them to become better parts of society. There are many who believe that halfway houses are not a good thing and would rather not have them but there are many reasons that these people are not looking at the whole picture and are not looking into the benefits that halfway houses can provide. There are many reasons that the surrounding neighbors and communities could fear a halfway house. Some of these reasons are the stereotypes that are associated with these places. This means that there is the common thoughts and beliefs that those who are in the halfway houses are not truly ready to be reformed and therefore it can be thought that these individuals should remain in prison. This is a misconception as the halfway house provides the individual with stability and helps them to be able to transition into a life outside of prison. The halfway house often provides the individual with a way to be able to find employment, get hooked up with needed medical and other health care services including rehabilitation and mental health, and a way to be able to live until they are able to stand on their own two feet (Welsh and Harris 2009). Without halfway houses these former criminals would be left on their own to find all of these resources and many times in the past the individuals had a hard time finding these things which has resulted in them committing more crimes. With halfway houses the return rate to prison is lower. Another problem that many individuals have with halfway houses is that they do not understand how giving the individual a place to live is really what they deserve. However there are some new programs that are offered in some halfway houses where the perpetrators of crime are forced to pay restitutions to the victims of their crimes. These programs have been successful in the satisfaction for both the perpetrator and the victim. In a recent study on this issue, the results were found to be positive for all that were involved (Bonta, Boyle, Motiuk, and Sonichsen 1983). Another common misconception is that the residents of the halfway house are not ready to be in the real world when they leave and that there is a high rate of repeat criminal offenses. This was looked at by a group of researchers and what was found was that those who had successful completions of the halfway house programs were less likely to have repeat criminal offenses where as those who were not successful in their treatment through halfway houses (Hartman, Friday and Minor 1994). This is very important to note as there are many reasons that an individual would not have a successful completion but then when an individual did have a successful treatment that they should be allowed the benefits of reformation and believed to be reformed and hoping for a better life. Halfway houses can be very beneficial to both the former criminals that inhabit them and the local communities in which they are located. In many cases halfway houses provide a place for these former prisoners to live while they are working on getting back on their feet and becoming stable. Halfway houses and their programs beneficial to the individual as they are not on the street or trying to make it on their own in a world where it is more difficult for them to find a place to rent, obtain employment or anything else. The benefit to the community is that these former criminals are off of the streets and in a place where treatment and supervision is mandatory while they are becoming more stable. Thus they are less likely to commit petty offenses like theft in order to eat or make money for needed items.

Carbon Fiber Reinforced Polymer (CFRP) Uses and Properties

Carbon Fiber Reinforced Polymer (CFRP) Uses and Properties CFRP: carbon fiber reinforced polymer Urvish Gajjar In the end of 1800s first time Edison used the carbon fiber in the electricity bulb. CFRP- carbon fiber reinforced polymer is a one type of the carbon fiber. Edison used the fiber into the filament of bulb but he was unsuccessful because his fiber produced by carbonization of cellulose stand such as cotton or from bamboo. Because of the not specific design and not specified properties his fiber was failed. Then after that time the research was start on fiber and in the middle of the 19th century carbon fiber used in insulation or in high temperature furnaces and in the industries like chemical plants and mechanical plant where we need some strength material. Before end of 19th century the increment shows in the carbon fiber field when the manufacturing process developed very well and allows for high modulus and high powerful fiber the reinforced process apply to the fiber and then they find the new type of carbon fiber which is CFRP. In Japan, first time work done in the CFRP field by 3 scientist of Japanese bureau of industrial technology. They were using poly acrylonitrile – PAN in the base material to manufacture carbon fiber this fiber had a high degree of molecular orientation. Then from that days the improvement is in process and now a days we can use PAN is major material in common use. The high stiffness and strength properties and low mass of CFRP have lead to more use in the aircraft and other industries. In 1977 CFRP use as skins in the aircraft. It was used in the vertical fin box and leading edge in the F-16 air force aircraft. CFRP has a very different properties one of its property is a very low co-efficient of thermal expansion that’s way it can used in space air craft because space aircraft has been work in the galaxy and there the temperature is between -110c to90c. Then in the 1980 CFRP was taken as reinforcement to strong then concrete beams then they people use carbon fiber poly mer in reinforced process and got the CFRP. So that’s a short past about the carbon fiber reinforced polymer In the synthesis or in making of the structure of CFRP in this composite more than two materials can be use so in the first step one material can be take as a basic or supporting matrix and at that time the second material build a structure on that base and reinforced the the hall material . this process is a very complex and costly .this hall process can be work under the certain temperature and pressure . After this process an epoxy can be filled out on the base material and make a hard and strong material then after the material cooled out . the mixture can produce by fiber of the different material in the main matrix. This way we can produce the CFRP from the carbon fiber. Fig 1. CFRP bond view In the Fig 1 we can see the large view from the gap of the two layer and how to build the layer of the polymer. In the aircraft the part of the aircraft need a strong tensile strength and the need the material which can not react on the environmental condition. So CFRP satisfy all this condition so it can be easily used in the aircraft industries for making the wings, tail of the aircraft For aircraft most important is the properties of the material which is used in manufacturing of aircraft because if the material has not sufficient properties related to aircraft it can be fail in future . CFRP is a one type of composite material. So it has a mixture of the two material so, it has two different kind of properties of two different material. CFRP has two part one is matrix and another is reinforcement. Second part is fiber so they give a high strength and first one is polymer which give a rigidity.In that because of carbon fiber CFRP has a high modulus of elasticity. And also have a low density, high tensile strength and last one is most important which low chemical reaction which is most useful properties for aircraft material. Fiber has a many different type of composite material but CFRP is a special one because it has a many positive properti9esw and many advantage given composite material the start with it’s advantage CFRP is a very strong material but with the extremely light weight it has been used in internal part of aero plane and car’s structure. The good thing about the CFRP is it has a high strength, rigidity, resistanc3e and low corrosion. so that’s way it is use in various important structure component. There are in composite material other material also have a good properties but CFRP is manufacture in specific condition so because of that reason CFRP has a good properties then other composite material .especially in field of aviation and space lights. This reinforced polymer s are the incredible potential see on other benefits of this material is that it is a low thermal expansion so it cannot more contract orexpand in such a different thermal condition. CFRP is a less corrosion properties because when the material manufacture with the specific resins, carbon fiber is used ant this one is a most corrosion resistance material so it is a less corrosive. We see the different advantage of CFRP is durability, radiolucency, electrical conductivity and ultra-violate resistance. CF is transparent to radian and invisible in X- rays so CFRP is radiolucency. Every material has a benefits and a drawback. CFRP also have some disadvantages. This material is very costly and its structure is very complicated and complex. It is a creep, low flexibility and brittleness material. In its disadvantage one of the major is that in the manufacturing time if there some mistake happen or process run improperly themn the hall material is useless and we can not use that material any more. So in it’s production time have to very carefull and we need special skilled worker. CFRP’s uses are increase day by day because now a days people need a reliable and easy accessable products. CFRP is a l0ow weight and good properties so people used this composite material in different field . In aerospace industries there are highest use of this material In past first aircraft made by composite material in that almost half percent material is CFRP. Then the branded car rolls-royce also use this material in that cars and bow a days in automotive, civil that’s all engineering field increase the use of the CFRP. If we see the different field like a sports , music and kitchen thaqt’s goods are make from the CFRP. In in future in this world mostly products are make from the carbon fiber. Second, in medical field dentist use the machine for operation that’s all are made from carbon fiber. So, we see small part of machine to Hugh aircraft all where we use this material. Fig. 2 composite material used in aircraft Source:educare-zone.blogspot.com If we see from environment engineering site, the nature is give a high thinking and attention from today’s community. This is right for composite material as well. As we see ahead , that composite material is a light weight and high strength, that’s affect the environmental but it is low compare to real material like steel. Yes some time if we make a wrong composition for material that time its affect the nature .polymer is only affect by it’s pollution not other way. So, at last, CFRP is a good composite material if we use it perfectly References History of carbon fiber http://www.hj3.com/company/history-of-carbon-fiber/ Sarah Lynn Orton.

The play entitled â€Å"The Tempest† written in 1610 and later published in 1623 is one of the great comedy plays by William Shakespeare. The themes illustrated in the play are freedom, friendship, repentance and forgiveness. Its protagonist is an enigmatic character named Prospero who wields the compelling power of the magic arts. Prospero, the former duke of Milan and his beloved daughter have been stranded on an island for twelve years. Disappointingly, his own brother Antonio exiled him and his daughter with the help of Alonso, the king of Naples then he unrightfully claimed his brother’s position as the Duke of Milan. The vessel that they travelled in was filled with: some food, some water, and also precious books belonging to Prospero-the supplies had been packed by the king’s counsellor Gonzalo who sympathized with Prospero’s situation. An elegant spirit named Ariel was enslaved and imprisoned by Sycorax an evil witch who previously inhabited the is land. Because Prospero studied magic from his books he managed to rescue the spirit who is now compelled to serve Prospero until he is released. Prospero also gains another companion, the son of Sycorax, Caliban. He cared for him and taught him language and religion in exchanged for learning how to survive on the island. However, Caliban tried to rape Miranda and the consequence for this was enslavement and now both father and daughter look down on Caliban with disgust. Astonishingly, a ship passes close to the island containing Alonso, his son Ferdinand, Sebastian, Antonio and Gonzalo. Prospero has his chance to avenge his enemies so he brews up a storm with the help of his spirit... One of the reasons why this drama is so popular is because of the type of language used by the prota... ... Prospero relies on Ariel to help him. Using all of the information that I gathered, it is now clear that Prospero is just and fair, in addition to intelligent. Prospero's magic is the white magic of nature, not the black magic of evil men. This former duke of Milan is a complex personality. Although he refuses to free Ariel and enslaves Caliban, Prospero is really a beneficent ruler, never intending to injure even his enemies. Early in the play, Prospero appears callous and cruel, especially in his treatment of Ariel and Caliban. Social and historical context in the play: In the 400 years since the play was written, attitudes to many different things have changed, including the idea of colonialism and slavery. Caliban, in a contemporary context, represents slavery and the exploitation of natives and their lands when the Western world takes over their continent.

Irrepresive Individuals :: essays research papers

The Irrepressible Individual in the Works of Shirley Jackson Throughout her life, Shirley Jackson struggled with a conflict between her dogged individuality and society's requirement that she adhere to its norms and standards. Jackson saw a second level of human nature, an inner identity lurking beneath the one which outwardly conforms with society's expectations. Society's repression of her individuality haunted Jackson in her personal life and expressed itself in her writing through the opposition of two levels of reality, one magical and one mundane, but both equally real. All of the various dichotomies that make up Jackson's double-sided reality can be traced to the hidden human nature, the repressed individual she saw within each of us. From an early age, Jackson did not feel completely comfortable in the society around her. She preferred to sit in her room and write poetry rather than play with the other children in her neighborhood (Oppenheimer 16). Alone in her room, Jackson explored the magical worlds, the alter-egos which her family did not understand. "I will not tolerate having these other worlds called imaginary," she insisted (Oppenheimer 21). Jackson did not satisfy her mother, a wealthy socialite who wanted her daughter to be beautiful and popular and was disturbed by her talk of "other worlds." Relations between Jackson and her mother were tense throughout her life, paralleling the conflict between Jackson and the society in which she found no place for herself. "I will not tolerate having these other worlds called imaginary" -Shirley Jackson Jackson's mother wrote to her once that "you were always a wilful child" (Oppenheimer 14). This careless statement captures Jackson's stubborn assertion of her individuality, as well as her mother's disapproval. Jackson's obesity particularly troubled her mother, who suggestively sent her corsets even after she was married (Oppenheimer 14). Being overweight symbolized Jackson's rebellion against her mother and the standards of fashionable society. Her obesity demonstrates the connection Jackson made between her unique individuality and the "freakish and abnormal, the 'grotesque and arabesque'" (Sullivan n. pag.). The abnormal second reality Jackson contemplated in the seclusion of her room was to her supremely ironic. Jackson rarely ends her stories with a resolution of the plot; instead, a dramatic incident or revelation serves to illustrate the irony she sees in the world. In her most famous short story, "The Lottery," Jackson takes pains to describe a village of hard-working, upstanding Americans.

Leonardo Di Ser Piero Da Vinci

Leonardo was a man of many different talents; among those talents were polymath, painter, sculptor, architect, musician, scientist, inventor, engineer, writer, geologist, anatomist, cartographer, anatomist, and botanist.

Developmental Psychology Essay

Cognitive development involves developing concepts of thought, problem solving and memory (Green. 2002). Jean Piaget (1896-1980) and Lev Vygotsky (1896-1934) were both psychologists, which focused on cognitive development and the way in which children’s thought and reasoning developed as they matured. This assignment shall begin by describing and evaluating the theories put forward by Piaget and Vygotsky referring to research evidence and providing a conclusion. Piaget (1896-1980) was one of the most influential researchers in the area of developmental psychology during the 20th century and a as biologist was interested in the way in which organisms adapt to their environment this was described by Piaget as intelligence. He viewed behaviour or the adaptation to the environment as being controlled through mental organisations known as schemes that the individual uses in order to represent the world. Piaget suggested that adaptation is driven by a biological drive to obtain balance between schemes and the environment, which is known as equilibrium (Huitt. 2003). Within Piaget’s research and writing’s on cognitive development he suggested that children’s thoughts are not only less sophisticated than adults but they are also qualitatively different and this is due to less knowledge (Jarvis. 2000).   It was considered by Piaget that the interaction between the child and their environment was the main factor of influence on their cognitive development. Piaget’s view of children is that they are scientists and that they should be left to explore their surroundings giving them the opportunity to interpret the world in their own way. The active involvement in their own learning is described as a series of schemas and that these schemas would change and develop through each stage through the process of assimilation or accommodation (Green. 2002). Piaget’s theory is based on stages of development in which he believed that all children develop at the same age. There are four stages to his development theory, which are sensorimotor (0-2 years) and the view that infants are developing their first schemas (Meggitt. 2000). Object permanence is the main focus within this stage and the assumption by Piaget that children aged five or six months old could not understand that an object, which was covered, still exists.  An experiment showed that a child of five or six months showed no interest once the toy was covered whereas a ten month old would reach out for the toy and seem to become agitated. Piaget’s interpretation of this was that the child of ten months had reached object permanence and now has a schema for the object. In contrast to this Tom Bower and Jennifer Wishart (1972) argued that objects do still exist in baby’s minds although they have been covered. To support their theory an experiment was undertaken using an infrared camera. An object was offered to the baby and as they reached out to grab it the lights were switched off. The results showed that the baby was still attempting to reach for the toy although they were unable to see it and so an explanation for Piaget’s theory was that by covering the object the baby was distracted and not necessarily that they had forgotten about it. The second stage is pre-operational stage (2-7 years). Egocentric thinking predominates the child (Huitt. 2003) within this stage and they do not have the ability to understand things from another person’s viewpoint according to Piaget. In order for this to be confirmed he set up an experiment. Three mountains were set in front of the child and a doll was placed in different seats around the table. Photographs, which had been taken, were then shown to the child and they were asked to point to the picture that the doll would see. As Piaget’s findings showed that most four or five year olds pointed to photographs which represented their view of the mountains he concluded that they were egocentric. Most children aged seven that was asked to do the same task correctly identified the photograph strengthening Piaget’s theory. Although it was then argued by Martin Hughes (1975) that the task was much too complicated for the child and therefore devised his own experiment, which would contradict Piaget’s findings. His experiment involved a model with two intersecting walls, two policeman figures and a figure of a boy. After having a trial using one police figure and the boy to ensure the child understood the task Hughes began his experiment. It was found that most children could successfully take account of two different viewpoints. Therefore it could be said that Piaget’s experiment may have been too difficult for the child to understand rather than the child being egocentric.

In report format, prepare a services marketing mix (people, process, Essay

In report format, prepare a services marketing mix (people, process, physical evidence) for the service offering on which you based assignment one - Essay Example It will provide the firm opportunities and to reduce the impact of threats. In this case, Holiday inn Hotel has to make adjustment of the traditional 4Ps marketing mix that entails product, price, promotion, and place and adopt more Ps, which include process, physical evidence, and people to achieve its marketing objectives. Useful marketing objectives must be specific, measurable, achievable, realistic and timely (SMART) (Wilson and Gilligan, 2004). The marketing objectives should be based on the situational evaluation of the environment of the company (Lambin, et.al. 2007). In this case, Holiday Inn should use its strengths to eradicate its weaknesses and respond to threats in the industry (Doyle and Stern, 2006). Moreover, marketing objectives should aim at exploiting market opportunities that will enable the company compete efficiently and attain a higher market share in the industry (Kotler, and Keller, 2011). The first marketing objective of Holiday Inn should be to enhance its presence in the upcoming markets such as China and Dubai by 15 percent in the next five years. The Asian market offers abundant growth and profitability opportunities due the high growth in consumer revenues, good infrastructure and growth in tourism numbers; therefore Holiday Inn should expand its presence in those markets. The hotel brand has huge financial resources and human talent thus it is possible to use its learning experience in the hospitality market to attain high market share in Asia (Ariffin and Maghzi, 2012). The second marketing objective for Holiday Inn is to increase the current bed occupancy by 25 percent in the next five years. The goal is specific and attainable since the global tourism travel numbers are increasing while the wealthy global economy will lead to a rise in international business travel.

What caused the Revolution of 1911-1912 in China Thesis

What caused the Revolution of 1911-1912 in China - Thesis Example A great percentage of them disliked the kind of ruling by the Qing dynasty that had been existent in the country for a very long time. The otherwise called Xinhai revolution, on a great extent can arguably be caused by be deficient in of able Ching emperors to rule the country. In the work of Ho, the inability of the Ching emperors to rule the country instilled a lot of violence among the citizens1. This work continues to bring out the view that, in as much as the dynasty was the most prominent, the fall of that dynasty created numerous issues for the country’s well being. By the 19th century, the dynasty was completely inflexible which saw the country experience a lot of challenges in terms of rebellions in the country, poor economy, imperialism from the west, poor produce and sales. By the end of 1911, the country had already gone through rebellion from the citizens. In 1912, Henry Pu Yi, the then emperor, stepped down from the leadership position to pave way for more reforms. From the work, it is evident that the emperor was clearly not needed by the citizens and was sapped by the revolution in 19122. A critical analysis of this situation brings out a clear indication of the fact that the major reason behind the revolution is that the Chinese pop ulace did not appreciate the manner in which the country was being run by the Ching dynasty. With poor leadership, it is evident that the misappropriation of funds would have its way, just like in the case of China. This misappropriation of funds led to the country being overtaxed, and the taxes fell in the hands of a few people. With the population growing on a tremendous manner, the dynasty could hardly deal with the demands of the populace, which in turn led to the revolts among the populace. In this work, it is apparent that the Qing dynasty was completely ineffective3. With this in mind, the Chinese citizens could not wait for the providence of the administration to lapse their hopeful

Analysis of Galanin Using Mass Spectrometry Essay

Analysis of Galanin Using Mass Spectrometry - Essay Example It is reported that obese human beings have been observed to have high levels of serum galanin; this suggests that peripheral galanin has a role to play in the regulation of balance of energy and that high circulating galanin levels are a contributing factor to the development of obesity and obesity-related metabolic impairments. In their findings, they report that high levels of galanin in the serum can help regulate body weight, metabolic rate and carbohydrate-lipid metabolism through a mechanism that does not depend on the feeding regulation Galanin may also be responsible for high altitude induced anorexia. Singh et al. (2001) carried out studies on the roles played by galanin and neuropeptide Y in high altitudes in food uptake. Male Sprague-Drawley rats were exposed to conditions mimicking those at a high altitude of 7620 meters for 1, 7, 14 and 21 days for a six-hour period each day and to an altitude of 6096 meters for a continuous 72 hours to study the effects of intermittent and continuous exposure. Galanin and neuropeptide Y levels were estimated in various parts of the brain and plasma of exposed and unexposed rats. They found that plasma galanin levels decreased in both groups of rats. They asserted that the changes in the levels of galanin may be responsible for anorexia at high altitudes. Galanin signaling occurs through three G protein-coupled receptors. After mucosal stomach biopsies, the galanin can be analyzed using mass spectrometry. The technique Mass spectrometry involves measuring the mass of a compound, this with very high sensitivity. Mass spectrometers require molecules to be charged and in gaseous form for analysis. Peptide molecules in galanin being large and polar, are not easily transferred into the gas phase and ionised. Electrospray (ES) Fenn et al (1989) and matrix-assisted laser desorption ionization (MALDI) Karas and Hillenkamp (1988) are the ionization techniques that are used to transform the galanin into the gas-phase. Mass spectrometers measure the mass/charge ratio (m/z) of analytes. Mass spectrometry and MS/MS is applied in protein study as it makes use of the large array of genome and protein data stored in databases. The lists of peak intensities and mass-to-charge (m/z) values produced by a mass spectrometer can be processed and compared with lists generated from the theoretical digestion of a protein or the theoretical fragmentation of a peptide. Mass spectroscopy makes use of the fact that many protein molecules can be adequately displayed on a single gel. This technology was developed in the 1970s, as noted by Klose (1975) and O’Farrell (1975). Identification of the spots separated on these gels remained laborious and was limited to the most abundant proteins until the 1990s, when biological mass spectrometry had developed into a sufficiently sensitive and robust technique. In the analysis of galanin using mass spectroscopy: 1. The galanin sample will undergo vaporisation to transform i t into a gaseous form. 2. The gaseous form will then be bombarded by an electron beam to generate ions. 3. The generated ions are them separated depending on their mass-to-charge ratio by an electromagnetic field in an analyser. The analyser can be Time of Flight (TOF) or a quadruple ion trap. 4. The ions are detected. 5. The ion signal is processed into mass spectra. Ionization techniques 1. Matrix-assisted laser desorption ionisation MALDI Matrix-assisted laser desorption ionisation (MALDI) employs the use of an excess of matrix material. This matrix is precipitated with the analyte molecules (the analyte contains the galanin molecules to be analysed) by placing a very small volume of the mixture onto a metal substrate and allowing it to dry. This solid is then
