As I watched it, I took out the key components of folklore in the film. Im here to contend the point and reveal to you the reasons that The Lion King is a fanciful story. Above all else, one key component in the film that I discovered was administering a specific realm of town. In The Lion King, King Mufasa is the leader of Pride Rock, which is where the light contacts. Albeit all the creatures follow his order, it doesnt mean he has a tyranny over Pride Rock. Ruler Mufasa counsels the creatures to discover what is the best outcome. Then again, In the book, The Odyssey, Odysseus is the leader of his city, which is the island of Ithaca.

At the point when I consider legend in folklore, the name Hercules strikes a chord. He was a genuine legend, continually helping individuals and attempting his best. A legend doesnt fundamentally need to consistently spare individuals. They simply need to consistently be attempting their best and vanquishing what they really think ought to be.

Scar is certainly a cheat from numerous points of view. ... <!

The Letters From The Civil War Time - Free Essay Example
The Civil War of 1861 to 1865, was the premise of a change that would forever alter the face of a diverged country. The conflict between the North and the South involved problems starting with militia precursors, to moral and economic struggles. The Civil War would not be understood without being recorded through the words of soldiers and their families. Historical letters contain such details. Letters such as the one from Ruth Maria Strong, who was writing to her son in 1862 warning him about a typhoid fever going around, while still providing him with the only thing more important than the war her motherly love. Another letter in that same year, written by Captain Charles Scott, described the horrors of one of the deadliest battles; Battle of Shiloh. In his 4-page letter he describes the morning of the attack, as well as writing about his coward troops. This type of context helps gain a better understanding of the lives of troops during the Civil War, as well as sympathize for them in the sense that they are risking their lives in what would become one of the biggest wars for America. To begin with, when looking back at the Civil War, soldiers from opposing sides can be seen as savages, but within those conniving minds, there is an individual that loves them. Such proof can be found in letters such as the one from Ruth Maria Strong, who was writing to her son. Union soldier, Arthur Tappan Strong, was a 42nd Ohio Volunteer that was under the control of Colonel James Garfield. Showing indications of motherly love, Ruth states, I sent you one pair of socks, which mother knit for her soldier boy, may he live to need more (Strong, 1862). Documentation like this suggests that Ruth was merely concerned for her sons life. Her letter also shows how sending knitted socks to her son was a reoccurring event in her life, and she is willing to make more for him, if he lives. The main point here is that there is an obvious worry lurking in Ruths mind. Furthermore, in the second page of her letter she also writes, We hear that the typhoid fever is among you (ibid). This is a very spine-chilling statement that must be horrific to read as a troop. The typhoid fever was an infectious disease that is received by drinking or eating contaminated food, and this was what took the lives of 80,000 soldiers during the Civil War. Ruth is explaining to her son what to do if he is exposed with typhoid fever. She is giving him several instructions, such as getting pure air, being as quite as possible, and to wash with tepid castile soap, (ibid). As a soldier in active duty, the last thing they would have wanted to agonize about is getting infected. The typhoid fever was ironically not only the cause of Arthurs death, but the deaths of 65,000 Confederate and Union troops. As it happens, life as a soldier was all but an enjoyable excursion. They had to spend most of their time fighting off other problems such as; lice, ticks, chiggers, and mosquito s (America: A Narrative History, 2016). This goes to show that Arthurs death was a tragedy that was bound to transpire. The chances to have survived these different afflictions in a time of poor medical advancements, was all but pleasurable. The fact that Ruth had to write to her son apprehensively about a deathly fever could make readers feel a hint of compassion for those who were seen as the enemy. Equally significant, with the many battles of the Civil War, there is one prestigious clash to mention; The Battle of Shiloh in 1962. After Grant made a costly mistake in revealing 42,000 of his soldiers in the eyes of Confederate General Johnston, the Union was attacked at a surprise (America: A Narrative Story, 2016). Nevertheless, it consisted of a Union victory in the sense that Commander Ulysses S. Grant fired a counteroffensive amongst the line known as Hornets Nest. With this tactic, the North was able to overpower Confederate forces, and advance them further into the northern Mississippi (Battle of Shiloh Facts Summary, 2018). Moreover, letters from troops of the Battle of Shiloh is a rarity. One significant letter that was written in 1963 from Captain Charles Scott, is exceptional in showing the horrors of the battle. In his letter, Scott writes to his wife the morning of the attack, I do not yet know what may be the result, but from the persistency of the attack, there mus t be a heavy loss on both sides (Scott, 1962). What Scott meant with this phrase was that he believed the battle was going to be bloody he was right. The Union had a count of 13,047 casualties, while the Confederates had 10,667. One key point in his letter was that he mentioned some of his men were cowards for trying to retreat to grasp protection in the boats. I saw them drown. And I assure you they were the first Men I ever saw drown that I was willing to stand and look on without trying to render them assistance (ibid). Many would consider this to be a deceitful action by Scott in letting his own men die, but in reality, those men that were trying to escape, were not dutiful in the Union. This proves that even while succeeding, several men in the Union could not seize to do anymore fighting, especially when participating in the horrors of the Battle of Shiloh. To conclude, both the letter from Ruth Maria Strong, and Captain Charles Scott have one thing in common the negatives. Ruth Maria Strong has shown love towards her son when he most needed it. In her mind, the idea about her sons death ponders within her mind, but that doesnt let her have a whit of ambition. Charles Scott on the other hand, within experiencing what no one else could imagine in todays world, closed his letter with saying that he had not slept in 60 hours, and assures his love to his wife Anna (Scott, 1962). Both letters are in no sense of the same topic, but they do present a clear idea of the Civil War for the North in 1862.

Personal Statement On Social Work - 912 Words
Prompt #1 My intended major is Sociology. Once I earn my degree I intend to find a career in either social work or teaching. In choosing social work my focus will be low income families and programs that decrease social inequality. As a child I yearned for the ability to help people, to change someoneââ¬â¢s life for the better and give them back the strength and hope they have lost through lifeââ¬â¢s battles. I gained this eagerness to provide assistance when my parents brought me to their homeland of Guatemala. Guatemala is a very poor country and I saw the despair and hopelessness of many while others still strived every day to elevate the lives of their family amidst poverty. As I got older those thoughts were always on my mind. It wasnââ¬â¢t until I took a sociology class my senior year in high school that I learned about social work and its role in serving those in need. Learning about social welfare programs brought back all my memories and reassured me there were careers that fit my aspirations. At Glendale College I took more Sociology courses and found it to be a perfect fit for me. My favorite class was Introduction to Social Work since it introduced me to different sub fields within social work, working with homeless, distressed and low incomed families.

Leadership Theory And Practice Of Leadership - 874 Words
Throughout the entire course of this class, I have been asked to fill out different self-assessments related to whatever topic or approach to leadership Peter Northouse (2013) was discussing in his book Leadership Theory and Practice. Each one of these self-assessments were intended to help me in discovering who I was as a person and a leader. Some of the leadership self-assessments included the Least Preferred Coworker Measure from the Contingency Theory chapter, the Leader-Member Exchange Questionnaire from the Leader-Member Exchange Theory chapter, and the Servant Leadership Questionnaire from the chapter that discussed Servant Leadership. Many of these questionnaires I found to be very effective in helping me discover more about my personality traits and leadership style. Before going through this journey of self-discovery, my view of leadership was accurately described by John C. Maxwell ââ¬Å" Leadership is influence.â⬠(Maxwell, para. 25, 2012). I believed, before taking this class and Northouseââ¬â¢s (2013) assessments, leaders were defined by the extent to which they could influence others to achieve company goals. I thought that, when discussing leadership, the leader was the most important aspect of the leader-member dyad and that it was the leader who had the greatest influence over how successful the organization was.

Currency and Low Valued Yuan free essay sample
Kerimova Aysha Wal-Mart and the Yuan Debate 1. Why is the value of the yuan so important? Wal-Martââ¬â¢s business strategy relies on low production costs which it can pass on to its customers. If Wal-Mart were a country then it would be Chinaââ¬â¢s eighth largest trading partner ahead of Russia, Australia, and Canada. Wal-Martââ¬â¢s non-Chinese owned suppliers operating in China number nearly 5,000 and all of them benefit from a low valued yuan compared to the dollar. The 176 million worldwide customers of Wal-Mart also benefit from the low valued yuan. With nearly 70% of Wal-Martââ¬â¢s products coming from China a sharp increase in the value of the yuan against the dollar can be devastating for the company as the increased costs for Wal-Mart and would most likely passed on to customers. It could also hurt American customers whom Wal-Mart claims it saves the average household roughly $2,500 dollars every year. 2. If you were the CEO of Wal-Mart and were preparing for a meeting with the most vocal members of the US Congress on Chinaââ¬â¢s currency ââ¬Å"manipulationâ⬠, what would you say to them? I would point out that while it may be politically easy to blame China especially when it comes to an uniformed electorate, the rise in costs associated with policies aimed at encouraging China to lets its yuan to appreciate against the dollar will do harm in other ways. Average Americans (also known as voters) will feel an appreciated yuan in their wallets. China may be an easy target, but the higher costs American consumers pay due to policies pursued by members of congress is another hot topic that potential voters will respond to. Finally increased costs means Wal-Mart will have to take actions to keep profits up to keep shareholders happy. This may mean cutting workforce which in this current economic environment where so many Americans are looking for work would not be a good thing. I would also point out that Chinaââ¬â¢s yuan value against the dollar is not entirely due to simple government manipulation. In fact since 2005 amid pressure from the United States the yuan has risen 23% in value against the dollar. Analysts believe that the yuan will depreciate as much as one percent this year not because of government manipulation, but because of slowed economic growth which has decreased Chinaââ¬â¢s trade surpluses 3. Should Wal-Mart do something about the US trade deficit with China? There is an obvious incentive for Wal-Mart to pursue actions to keep yuan value low compared to the US dollar. In the long run it may be beneficial to play an active role in reducing or at least preparing for the reduction of the US trade deficit as a result of a stronger yuan. The United States has enjoyed being its currency being the world standard for many decades, but as other countries like China gain on the US economically there is a movement to change the US dollarââ¬â¢s status. Just a few months ago China and Japan announced that the two countries will begin trading currencies directly instead of using the US dollar as an intermediary Wal-Mart can prepare by hedging against currency fluctuations. If it hedges in anticipation of a yuan appreciation it can avoid the higher costs it would incur from its suppliers. Also forward contracts could be another strategy. Wal-Mart could agree to make a future purchase at current currency rates. These strategies are relatively short term solutions. In the long term Wal-Mart will have to do several things. First it will have to find other ways to reduce costs. This may mean finding other nations that may have a comparative advantage in the production of goods compared to China. It could also promote a ââ¬Å"buy Americanâ⬠marketing campaign if it is forced to return some of its goods production back to the US do to politics or the economics of the time. It can also pursue new markets. It currently operates 3,600 stores in 15 other countries. Finally in the long run the company structure and strategy may have to be revisited. 4. Assuming that the yuan will appreciate further against the dollar, what should Wal-Mart do? There are several strategies that Wal-Mart can employ to deal with an appreciating yuan. First, is hedging against currency inflation. This can be done through forward transactions. For example Wal-Mart can agree to purchase a certain amount of a particular product in the future for the current currency exchange rate. If the yuan appreciates against the dollar (also referred to as a Forward Discount) then Wal-Mart saved money, but if the yuan were to depreciate (also known as a Forward Premium) then Wal-Mart would lose money. (Peng, 2011) It can also engage in Strategic Hedging. That is it can spread its currency hedging activities though out a number of different countries to mitigate the risks associated with dealing with only one other country. The idea is if Wal-Mart were to lose in a currency exchange bet in one country those loses could be made up by another currency xchange gamble from another country. The company can also look into strategies that cut costs. In 2010 Wal-Mart in an effort to cut costs consolidated its store purchasing. The effort put Wal-Mart in an ever increasing position to buy directly from manufacturers. Before Wal-Mart has utilized and still does third party companies to purchase goods across the world. Wal-Martââ¬â¢s intended long term goal is to become its own buy er for 80 percent of its products. It is estimated that buying directly will save Wal-Mart anywhere from $4billion to $12 billion annually.

Observation of chemical change LabPaq free essay sample
Certain Chemicals like Bromthymol blue and Phenolphthalein can be added to other chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96à well plate. Each well number was recorded along with question number and name of chemicals involved. Two drops of a chemical were placed in a well along with two drops of another chemical. Chemical reactions and color changes were recorded in Data Table 1. Observations During the experiments a few problems were encountered. One of the chemicals provided differed slightly from chemical description in the lab manual. We will write a custom essay sample on Observation of chemical change LabPaq or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The lab manual called for the chemical NH3 which is Ammonia. The chemical provided was an Aqueous Ammonia solution of NH4OH. When holding up the solution of AgNO3 and NH4OH to a light source for 5 minutes it was observed that no reactions took place despite the information contained in the lab manual. Also while testing the household chemical Brite, It was observed that the Bromthymol Blue changed to a green color that was not observed in any other test involving BTB. Questions A. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). How would you test this material for the presence of sodium bicarbonate? To test for the presence of sodium bicarbonate you could collect a sample of the household product and add HCl to it and see if you observe any CO2 bubbles. B. You know what color phenolphthalein and bromothymol blue turn when testing an acid or a base. Use the empty pipet in the Auxiliary Supplies Bag to test several (at least 3) household items including household cleaning products with bromothymol blue. Rinse the pipet well before using it on the next household chemical. When finished with this experiment rinse the pipet well and return it to the Auxiliary Bag for use in future experiments. Name the items tested and record their results. What do these results mean? Refer to the last 3 rows of Data Table 1 for results and observations of the household chemicals. C. You found a sample of a solution that has a faint odor resembling vinegar. You are verifying that it is indeed vinegar and you add a few drops of phenolphthalein. The sample turns pink. What assumption can you make about this sample? You can assume that the solution is not vinegar because vinegar is an acid and phenolphthalein only turns a basic solutions pink. D. You decided to investigate if the new wave of Vitamin Water is pH neutral: neither too acidic nor too basic. Using BTB (bromothymol blue), you select five flavors of Vitamin Water to test. Three of the flavorà samples turn a murky green, indicating the likelihood of acid/base balance. Of the two remaining, one turns slightly yellow, while one remains b lue. What can you assume about the acid/base content of these particular flavors of Vitamin Water? You can assume that the vitamin water that stayed blue has a more basic content while the vitamin water that turned slightly yellow has a more acidic content then the three vitamin waters that turned murky green. E. You have read that a new brand of hair tonic is supposed to contain lead (an ingredient in Grecian Formula). Devise a simple test to confirm the presence or absence of lead in that hair tonic. A simple experiment to test for the presence or absence of lead would involve adding potassium iodide to a sample of the hair tonic. If you observe a yellow and chalky looking precipitate when you add the Kl there is most likely lead in the hair tonic.
