Negotiation - Essay Example The functions of communication are another feature that is important within the context of the negotiation process. Facilitation of the exchange of ideas and opinions between the negotiating parties is one of the functions of communication in negotiation. The functions of communication interact with other features such as the rules and the objectives of communication to influence the achievement of the goals of the negotiation. Chronemics are a non-verbal feature of communication that interacts with the willingness and commitment of the negotiating parties to resolve their conflict. Chronemics encompass aspects such as punctuality and patience that are crucial to the successful completion of every stage of the negotiating process (Wood, 2008). Finally, intentions are an important feature of communication that can affect the direction and success of the negotiation. Intention interplays with interpretation because most negotiators assume that whatever their opponent does or says is purposive and is meant to communicate something. As such, there is need for negotiators to be fully aware of their intentions when saying or doing something in every stage of the negotiating process in order to avoid being construed inappropriately (Wood, 2008). Nicholas Anderson’s post is an insightful piece that presents quite accurate information on the modes of communication. The idea that written communication helps make up the shortcoming of verbal communication to come out as abrasive is correct because the person communicating has more room to read and correct what he or she has written wrongly. His assertion that verbal communication is the mode of communication that many people are familiar with is acceptable. However, he overlooks the idea that it takes much interest and attention to catch sadness or happiness in a person’s voice because some people do not announce these things explicitly but only imply them. Anderson’s idea on

Eye Contact with Japanese Businessmen Essay Example for Free

Eye Contact with Japanese Businessmen Essay In Japan, the businessmen avoid eye contact. The businessmen would rather not waste their time and distract other men, especially their senior officers. Distractions may be embarrassing, especially when one should be focusing on the task at hand. In this research paper, comparisons among America and its culture will be displayed to accumulate ideas on why the Japanese avoid eye contact. There is more than one factor playing in Japanese customs on avoiding eye contact. This paper generates ideas from animalistic behavior, to parental control, to busy cities, to friends, to professional NBA players, and to a religion that began in the United States. Not only is eye contact distracting, but also unnecessary while the notion of withdrawing oneself can be seen as helpful to cope with certain conditions in the environment. As we study cultures we can determine the differences between countless etiquettes and mannerisms across the world. Looking at two separate countries, we can compare what is considered acceptable and unacceptable. Because we live in the Unites States, it is easy to know what we, as Americans, should do and not do in a business meeting. If American businessmen, especially ones who are uninformed, meet with Japanese businessmen, the possibility of embarrassing or offending the Japanese culture is likely when conducting business at an absolute or selfish angle. The Japanese culture maintains a business that is great on group effort and loyalty. With these certain characteristics, the Japanese take on many roles to support their ways of humility. This is why we can see the Japanese businessmen intentionally avoiding eye-contact with other businessmen during a meeting to preserve modesty. Business is a consolidation within man to form an agreement at peace. We learn from studies of history and animals that staring is a sign of aggression. When eye contact is made, a mutual reflection of a challenge (or fight) occurs. Both parties may not want to partake or antagonize a fight, but when the eyes of humans and animals alike connect, the brain will induce a chemical reaction that triggers responses in the body to take action in order to defend itself. Now in a business setting, the Japanese arent ones to create a fight when a disagreement occurs. This is a way to respect senior decisions to avoid acting naive. If we take a look at the American culture, we can see how American parents confront their children when the children are misbehaving. Young children will naturally want to stop all eye-contact and maybe even run away. To correct this behavior, parents are told to maintain eye contact while communicating with their child. This is a way to build trust in a healthy rel ationship. When we think of the word business, its easy for Americans to think of New York City, a place of a heavily, dense population of business trafficking. The place can be described as busy because everyone is running around while trying to get to their next business meeting. It wouldnt be considered rude if someone bumped into you by accident if they were rushing into a taxi cab. A newcomer to the city might, at first, be outraged, but in time city dwellers are accustomed to it. In Japan, perhaps eye-contact avoidance is another practice due to high population. The Japanese is one culture to like their privacy. A great way to ruin ones privacy is to intentionally engage in eye-contact, especially with a prolonged engagement. Imagine coming home from work everyday in public transportation and running into an unknown interval. One thing a person might do is make eye-contact with a stranger to see if the stranger is aware of this interval. Now imagine you are conducting a meeting and you come across some interval in your way. An instinctive reaction is to seek help. However, in an important business meeting, this is a devastating episode in which you may bring down a friend if he is unaware of this interval as well. The best thing to do, in Japanese customs, is to own up and not throw your best friend under the bus with you. How should you do it? Perhaps avoid eye contact and stay calm with your best manners at hand. The Japanese are known to close their eyes when they are listening intently. This is a reaction to block out from sensing other things that are going on in the room. In America, we can find many distracting things that are meant to distract you. If you go to an NBA playoff game and watch a professional basketball player attempt a free-throw at an away game, you will see almost everyone in the audience do their best to distract the player, in order for him to miss the free-throw. You will hear loud noises, see shirts waving, and even see fan memorabilia made, bought, and obtained for that sole purpose during a free-throw shooting. One American religion, called the Church of Jesus Christ of Latter-Day Saints shows reverence similar to the Japanese eye contact phenomenon. During a sacrament meeting at the LDS church, many people will give talks or performances such as singing or violin playing. In one, hour long meeting, there may be up to 5 or more people conducting a session. After each person concludes their talk or performance, it is in the Mormon practice to show gratitude with reverence. The LDS members will keep quiet during the session without gossip or clapping to maintain the spirit. Comparing the Japanese to an LDS sacrament session, closing the eyes and being reverent is a way to block out an unnecessary force. As we can determine in an NBA playoff game, there is no room for respect. Players will have to play hard and with whatever comes in their way. Eye contact is a method to show people I am here. People have an ambition, or sometimes a reaction, to make ones presence known. We do it for attention, for work, or to make new friends. However, the Japanese have grown accustomed in a practice of avoiding eye-contact when things are busy and sometimes serious. In the business place, respecting senior officers is important to maintain ones own status while progressing in rank. It is important for the Japanese not to discourage other businessmen or to bother them during a stressful time. How else can one show respect than to maintain a personal boundary?

Civil Marriage In Lebanon Politics Essay

Civil Marriage In Lebanon Politics Essay Civil marriage has lately become a controversial issue in Lebanon. The media has been publicizing it quite intensively. It has even become a political issue debatable by most parties on both side of the political divide. The concept of civil marriage has gained much territory in this country and has already reached a point of no return. As such it can no longer be neglected or forgotten. Nowadays, civil marriage is legalised in most countries. It should, in fact, be encouraged here in Lebanon for several reasons. First, civil marriage is a right for believers and non-believers alike who wish not to marry in any or under the auspices of the religious institutions. In the absence of civil marriage, both believers and non-believers have only one choice: getting married in religious institutions. Civil marriage does not exclude religious ceremonies; it complements them, if so desired. The crux of the matter here is the right of choice. Lebanon does not offer that choice yet. MP Ghassan Mokheiber is one of the few politicians who support civil marriage in Lebanon, it should be one of the basic rights for the Lebanese people (Mahdawi, March 19, 2010). There is, nevertheless, a bright side to this issue. Despite the fact that the Lebanese people are deprived of this right on their own territory, they are, however, not deprived from their countrys recognition of their right to have their civil marriages carried out abroad. So, a couple who engaged in a civil marriage abroad is entitled to have their marriage fully recognized in Lebanon. Upon its return to Lebanon, the couples marriage is both legitimate and legal. Civil Marriage 3 Second, civil marriage is a blessing for men and women from different religious backgrounds who wish to enter into mixed marriage. In fact, it is the best refuge for secular arrangements. The progress of the secular culture has forced a regression of the religious option. This transfer of authority away from religious onto civil jurisdiction means that the power of regulating peoples live now lie in the hands of elected appointed civil officials. The clergy, stripped of its formal authority to regulate peoples civil lives, can no longer influence peoples choices in a secular state. In a country where civil marriage is practiced, the presence of a civil official simply validates the marital bonds of a bride and a groom away from religious conventional practices and authority. It is then a strictly civil affair. A clear illustration is when Rafik, a Druze, and Jeanette, a Catholic, decide to get married in Cyprus. Irrespective of their faiths, they can be joined in matrimony in a country where civil marriage is common practice. Rafik and Jeanette would have encountered several obstacles if they were got married in Lebanon. The first obstacle is that when one member of the couple is obliged to change to the religion of the other member; it seems as a conflict between religions. Given the society in Lebanon, most likely Jeanette will be the one to change. Furthermore, Druzes are not allowed to marry from another faith. Normally, people are born Druze. So, from a Lebanese religious stance, a Druze marrying a Christian would not be possible. Besides, Jeanettes family cannot allow for her to marry into a community other than Christian. Things can become even more complicated knowing that both Jeanette and Rafik are irreligious. Hence, the only solution for Jeanette and Rafik is to get married in Cyprus Civil Marriage 4 before a civil official leaving all their religious troubles as well as their religion-driven social taboos and customs behind them. Upon their return to Lebanon, the Lebanese authorities will legalize their civil marriage. Their married civilian status will then be clearly indicated on all their civilian extracts (No Civil Marriages in Lebanon). Third, civil marriage in Lebanon is a major step toward reinforcing interreligious dialogue. It helps build one Lebanese identity, which, in turn, will lead to a successful and healthy melting pot. One very important political decision consistent with this objective was taken as late as the mid 1990s. It was decreed that the religious denominations on identity cards be banned. This was the only successful of several failed attempts since the 1950s to legalize civil marriage in Lebanon (CopperWiki). Opponents, however, have always had the upper hand probably they were more vocal and more powerful. Their source of power could be either due to their formal position or to their leadership capabilities. One such attempt took place in 1998 when President Elias Hrawi was very close from introducing civil marriage into the Lebanese system. At that time, Prime Minister Rafik Hariri and some other ministers objected (Mahdawi, March 19, 2010). The reason why Hariri didnt accept to sign the bill was that Lebanon is not ready yet. Same as Hariri, and on the other end of the religious panorama, Lebanons Maronite Christian Patriarch, Cardinal Nasrallah Boutros Sfeir, declared that civil marriage is not in the line with the teachings of the Church. He also added that Solidarity with Lebanons Muslim community is a need (Yeranian, May 6, 1998, p.7). These negative voices have appropriately sparked many bitter criticisms. How does he want to establish this solidarity if hes an opponent of civil marriage, in the time that civil marriage Civil Marriage 5 is almost the only solution to live that solidarity? In another trial in 2002, human rights activists re-shed the lights on civil marriage, but unfortunately, without any success (Ajami, August 3, 2007). Finally, the simplicity and the expediency of civil marriage are far more convenient than the traditional ones. One blessing is not to worry about any delays or religious constraints. The presence of a civil official or a judge to join the couple is the only requirement. It is a practical arrangement for couples-to-be. A civil wedding ceremony may be arranged much faster than that of a traditional wedding. Moreover, civil ceremonies tend to be a favorite option given  the budget-conscious couples.  In fact, thousands of singles go through the civil marriage never to regret it. For the Lebanese, Cyprus is Las Vegas. Not for gambling, but à ¢Ã¢â€š ¬Ã‚ ¦ for marriage. While Las Vegas is the destination of choice for Americans looking to get married quickly, for the 400 Lebanese couples who travel to Cyprus every years seeking civil marriages, the decision is more calculated, (Luca, August 26, 2009). Besides, it is a most convenient half-an hour away refuge from Lebanon. In Cyprus, an average wedding costs less than $1,000; this sum represents 1% compared to the cost of a marriage that often reached thousands and thousands of dollars in Lebanon (Ajami, August 27, 2007). Civil marriage turns to be some kind of business where there are big financial profits. The famous slogan of Cyprus civil marriage is Just say I doà ¢Ã¢â€š ¬Ã‚ ¦ well do the rest.   The rest costs between $1,200 and $1,900. (Luca, August 26, 2009). Civil Marriage 6 Civil Marriage is just one chapter under the much bigger umbrella of civil society reforms that Lebanon needs to undergo badly. Other related problems that need to be addressed with equal urgency and importance include gender equality, child custody and divorce, which are all very closely related. Together with civil marriage, as and when updated, they compose the base for civil society. The current society relies on a complicated mix of religion. The first step towards modernization of our society should be its deconfessionalization. Religious leaders should be told to restrict their role to spiritual business specifically. Once our society turns secular, then other social issues, including civil marriage, would be addressed much more effectively. It is clear now that all the good and valid causes and benefits are there for as an immediate implementation of civil marriage regulations as possible. There is quite a dichotomy in the present situation: Civil marriage isnt allow in Leban on; while it is recognized if perform elsewhere. To many Lebanese the solution is very simple and could satisfy both sides: make of civil marriage a choice for interested couple (Mattar Law). The key to this solution is politicians, taking a courageous decision to launch the appropriate and serious workshop toward the implementation of civil marriages in Lebanon. The quicker such a decision, the quicker the solution. But, will it ever occur? And if so, how soon? Civil Marriage 7

The Farewell Sermon of Muhammad :: Islam Religion Essays

The "Farewell Sermon" of Muhammad The apostle continued his pilgrimage and showed the men the rites and taught them the customs of their hajj. He made a speech in which he made things clear. He praised and glorified God, then he said: "O men, listen to my words. I do not know whether I shall ever meet you in this place again after this year. Your blood and your property are sacrosanct until you meet your Lord, as this day and this month are holy. You will surely meet your Lord and He will ask you of your works. I have told you. He who has a pledge let him return it to him who entrusted him with it; all usury is abolished, but you have your capital. Wrong not and you shall not be wronged. God has decreed that there is to be no usury and the usury of `Abbà ¢s b. `Abd al Muttalib is abolished, all of it. All blood shed in the pagan period is to be left unavenged. The first claim on blood I abolish is that of Ibn Rabà ®`a b. al Hà ¢rith b. `Abd al Muttalib (who was fostered among the Banà » Layth and whom Hudhayl killed.) It is the first blood shed in the pagan period which I deal with. Satan despairs of ever being worshiped in your land, but if he can be obeyed in anything short of worship he will be pleased in m atters you may be disposed to think of little account, so beware of him in your religion. "Postponement of a sacred month is only an excess of disbelief whereby those who disbelieve are misled; they allow it one year and forbid it another year that they may make up the number of the months which God has hallowed, so that they permit what God has forbidden, and forbid what God has allowed." [Koran 9:37] Time has completed its cycle and is as it was on the day that God created the heavens and the earth. The number of months with God is twelve; four of them are sacred, three consecutive and the Rajab of Mudar, which is between Jumà ¢dà ¢ and Sha`bà ¢n. You have rights over your wives and they have rights over you. You have the right that they should not defile your bed and that the should not behave with open unseemliness. If they do, God allows you to put them in separate rooms and to beat them but not with severity.

Analysis of Rosemary’s Baby and Religious Faith

Is God Dead? Rosemary’s baby written by Ira Levin is a masterpiece of modern day horror that emphasizes the importance of religion. Rosemary, Guy Woodhouse’s wife and a young soon to be mother was raised by a strict religious catholic family. As she supposedly became agnostic towards her catholic faith, she left behind her an angry, suspicious father, a silent mother and four resenting brothers and sisters (Levin, 24). Throughout the novel we learn that Rosemary has re-embraced her religious beliefs and has never truly abandoned them.The author is also depicting a crisis of faith in the modern era explaining how there is a growing decline in religious belief in the 60’s. Rosemary regrets doubting and turning away from her religious beliefs after she discovers that pure Satanic evil does exist, and is residing next door. She re-embraces her religious beliefs as she utters a prayer â€Å"Oh Father in heaven, forgive me for doubting! Oh Jesus help me save my innoce nt baby† (287). This reveals how she seeks forgiveness of ever doubting gods existence and the power of religion itself.She is not only seeking forgiveness, but help for her baby. She realises that becoming agnostic and leaving her faith behind has allowed the devil to enter a doorway in her life. She re-embraces religion because it is her last hope since Guy, Doctor Sapirstein, the Castevets have all terribly deceived her: â€Å"All of them, they were all in it together. All of them witches† (257). This betrayal caused her to search for hope and to reconcile her inner conflict she had with her own faith. Moreover, as Rosemary is giving birth she apologizes to her baby â€Å"I’m sorry, my little darling!Forgive me! † (272). She is apologizing for being too late and for failing to protect her new born from the evil that surrounds her. Rosemary knows that if she had not put aside the importance of her catholic faith, this would not be happening. She then ask s the child for forgiveness because she feels that it is her fault. This foreshadows how she wants to accord importance once again to her religion. She feels that she could be forgiven if she became a true catholic again. At this moment she would do anything to save her child from â€Å"those witches†.Furthermore, Rosemary sees her helpless baby in a monstrous bassinet in the hands of the evil Satanists. She then proves re-embracement of her religious faith as she avoids collapsing and crying. Instead, â€Å"she shut her eyes tight to stop the tears and said a quick Hail Mary† (293). Even after all she has just been through, she still takes time to say a prayer. This demonstrates how she still has hope and faith. Additionally, not only does Rosemary go through evolution by re-embracing religion; she has also never abandoned her beliefs.When asked by the Castavets if she is religious, Rosemary's response is flustered and confused: â€Å"No, no not at all, I was brought up to be but now I am agnostic† (76). As Mrs. Castevet wanted more details about how she truly felt about the Pope and religion, Rosemary answers: â€Å"Well he is the Pope; I’ve been conditioned to have respect for him and still do† (77). This demonstrates that even though she does not think of him has holy anymore, she still has respect for him. This proves that the way her family raised her impacts her view on the Pope regardless if she is religious or not.As the Pope is visiting New York, Rosemary takes time to watch his appearance on television and to listen to his speeches. She mentions that the Pope’s speech at the UN â€Å"moved her† (102). Which reveals once again that he is important for her and that she respects him. As well, Rosemary receives a phone call from her sister Margaret and reveals an important declaration: â€Å"Religion doesn’t mean as much to me now as it did back home† (104). This reveals to us how religion r emains meaningful to her even though it is not as important as it used to be. As Rosemary wavers in her own beliefs, she does not abandon them.Furthermore, in Rosemary’s dream we perceive how she is in conflict with the beliefs towards religion and her agnostic point of view. She dreams of a church burning on fire and of catholic prejudices (113). Her unconscious reveals how her loss in interest with the catholic faith troubles her. In the dream, the Pope is also there with a suitcase and she asks him for forgiveness (116). This foreshadows how she wishes the Pope would forgive her for ever doubting the religion and how she seeks acceptance from him and her family. Lastly, the author is aiming to depict a crisis of faith in contemporary society.This is seen when Rosemary picks up a copy of Time magazine that was right next to her. â€Å"Is God dead†? It asked in red letters on a black background (255). This reveals how the society is doubting the existence of god. It a lso expresses the need for society to recognize that it is behaving as if God were no longer active in the world. The fact that the author took the time to mention this specific magazine foreshadows how Rosemary is not the only one doubting existence of god. As well, when Rosemary see’s the cover of the magazine she looks for the index right away and turned to the show business section (255).She did not read it because at that moment the existence of God did not mean much to her. This reveals how the God of the Christian past no longer served a function. For instance, the â€Å"Bramford† is a perfect example. Its morbid history of cannibalism and Satanism, infanticide and suicide, becomes reason for the growing decline of religious belief (26). Society is asking â€Å"If God does truly exist, how could he let these things occur? † 1,001 Words WORKS CITED Levin, Ira. Rosemary’s Baby. New York: New American Library, 1967. Print.

Modern times Essay

Janie Crawford, a free spirited individual, is the main character in the book â€Å"Their Eye’s Were Watching God† which was written by Zora Neale Hurston. It should also be noted that Hurston was an anthropologist because of the book’s historically accurate perception of the expectations black women lived up to during that time. The story unfolds around Janie’s life and how she fought against the male oppression she endured in her two marriages all the while trying to define herself as her own person. This oppression she endured with her marriages shows the influences and ideas that men had over women during that time period. If someone was to look at this novel in the perspective of an anthropologist you would have to say that it is a fictional novel with historical merit of how life was for women in the South during the 1920’s. The story scenes centers on a town and its citizens that was created as a black community. Not only was there oppression but also exploitation that Janie had to endure. In her first marriage to Killicks this was shown when he intended to put his wife in the field working the plows. Janie is powerless and without free will. â€Å"Ain’t got no particular place. It’s wherever† (31), Killicks claims. Killicks always was able to shut her up when he felt she was trying to assert herself. A good example was when he used derogatory threats against her family when she tried to talk about their marriage while shoveling manure. Then when the scorn wasn’t enough to keep her quiet the threat of physical violence began to be used. â€Å"Don’t you change too many words wid me dis mawnin’, Janie, do Ah’ll take and change ends wid yuh†¦Ah’ll take holt uh dat ax and come in dere and kill yuh! † (31). Joe Starks, her second husband, also exploited Janie by working her in his store. He seemed to silence her voice all too often. There were many times he would point out that she was just a trophy wife of someone in authority. Janie seems to be bothered by the high stool that Joe insists she sit on and when I first read that part I envisioned a child being punished. For this marriage silence is golden, on the part of the wife. The first time Joe quieted her, Janie said it left her feeling cold. When he refused to allow her to speak at his election for mayor she felt that it took, â€Å"the bloom off of things†. At the elections Tony Taylor wanted Janie to speak, â€Å"uh few words uh encouragement from Mrs. Mayor Starks,† that is when Joe takes the floor and says, â€Å"mah wife don’t know nothin’ ‘bout no speech makin’. Ah never married her for nothin’ lak dat. She’s un woman and her place is in de home† (42). A belief that held true for sometime even in today’s world. It was interesting that Stark used verbal cues to make Janie shut up and be obedience using her looks or intelligence as tools for his oppression. If you were to ask any battered woman today they too would say how insults and put downs helped in breaking their self esteem in order for their oppressor to gain control. In Janie’s first marriage violence was always just a threat; in her marriage to Stark it became real. Stark beat her over a poorly cooked dinner once (68) and for insulting his sexual abilities he struck â€Å"Janie with all his might† driving â€Å"her from the store† (77). Killicks on his last day with Janie threatens to kill her, Stark when bedridden and helpless wishes â€Å"thunder and lightnin’ would kill her! † (83). Violence goes hand and hand with oppression and exploitation. The threat of violence physical or verbal has consequences that follow the victim throughout their lives. Janie was basically just property in the eyes of her men. To do whatever their bidding and was often thought of as no better than a mule. There was one part of the book where it talked of a man that did not like to beat his wife because he felt it was just like stepping on baby chicks. He used empathy instead of moral rights as to why men shouldn’t beat their women. Are women thought of as just baby chicks or mules? The answer is yes and still can be applied in modern times.

Samuel de Champlain essays

Samuel de Champlain essays Samuel de Champlain was born in 1567, in the town of Brouage, Saintonge, on the Bay of Biscay in France. Very little is known of his family, other than his father was a ship-captain. Fairly early in his life, he joined the army and became quartermaster for the cavalry. Then, in 1599, Samuels uncle took Samuel to Spain for Samuels first voyage. There, Samuel took command of the St. Julien (The Virtual Museum of New France). He took his ship, and chartered to the West Indies. He landed at Vera Cruz, and even made it inland as far as Mexico City, and returned home after passing Panama, where he conceived a plan to make a canal across the isthmus (Samuel de Champlain). He reached Spain in March 1601. His journey was recorded in an account named Bref Discours (Historical Bopgraphies). He soon returned to France, whereupon French King Henry IV gave Samuel de Champlain a pension to explore land in North America. He sailed for the New Land on March 15, 1603, in the Pontgrave, with his eye set on founding a new colony. They reached Tadoussac on May 24 of that year. Tadoussac was a trading location where the Saguenay joins the St. Lawrence River (Samuel de Champlain). They set anchor here and rested. Soon after their arrival in Tadoussac, Samuel and a few of his men took a small riverboat up the St. Lawrence River. They continued until they hit the rapids of St. Louis, above current-day Montreal. They turned around and went back to Tadoussac, where they sailed back to France in August, 1603 (The Virtual Museum of New France). Before long, the brave explorer was back at sea. Sieur de Monts, a French Prince, had recently received new land in Acadia, and had it arranged that Samuel would sail to the New World and found a new colony (Champlain). Sieur de Monts sailed with Samuel to Acadia, where they landed at Sable I...

The beginning of the novel allows the reader to acquire a feel of what the Devon School was like during that clip period. Students of war age were invariably go forthing Devon to travel to the war, either by pick or by bill of exchange. Whether childs wanted to travel or non, the expectancy was ever present.

The nine met about every dark, and had particular inductions for the members. The nine was designed to give the male childs something to make because they were unable to take part in the regular things they did. The male childs at Devon were non holding the same sort of school twelvemonth that they had had in the yesteryear. Partially because of an interuption in their day-to-day lives. World War II had a strong influence on life in the novel A Separate Peace. The writer displays the influence through the character s actions and activities. The pupils at the Devon School were overwhelmed with the thought of war, and were thirstily expecting their going to an country of it. However, when a good friend returned from the war with a different thought of how it was, the male childs rethought their avidity. The male childs were forced to do up games and such to take part in to maintain them occupied when they weren t perusal. This novel showed that like with other major historical events, war can wholly change a manner of life, altering everything from personalities to activities.

International stratigic marketing - Essay Example t impose the values of emigrants onto another culture, on the other hand, the second outlook is universalist by nature which claims that ethics are implemented anywhere and everywhere in the world. Hence, the Universalist approach is based on psychological as well as economic ground. As a result, in order to resolve both the outlooks, it is preferable to attempt the comprehension of the cultural constraints that are capable of acknowledging home as well as overseas’ perceptions to the various forms and facets of bribery, which also contributes to the first measure in the modification. Following that is the second step which is the development of an international or local code of conduct which enables litheness within the hoary precinct. The ultimate consequence could be an evolving code which obliges many parameters of bribery for each nation’s present situation, in a way that is conciliation between the ethical, psychological and economic values of an emigrant’s business institution and of the regional professionals (Perry, 1992). International marketing is intricate for the sole reason that foreign environs are dissimilar to the home environs, for instance, they vary on physical, ethical, legal, economic, distributive and competitive parameters (Ball and McCulloch, 1996). Due to these environs, it is possible for marketers to oblige segments of the marketing mix for each foreign country or part. For instance, an organization may tend to change its packaging, advertisements and distribution channels in each of its international markets which are not very difficult to become accustomed with. As Armstrong et al quoted, such issues of marketing mix are not merely the ones confronting international

Macroeconomics Problem Set 3 - Assignment Example d. What will the capital-output ratio be at the Golden Rule steady-state? (Hint: recall from Chapter 3 that for the Cobb-Douglas production function, the capital-output ratio is related to the marginal product of capital). 1. In this question, we examine how the goals of the Federal Reserve influence its response to shocks. Suppose that in scenario A, the Fed cares only about keeping the price level stable whereas in scenario B, the Fed cares only about keeping output and employment at their natural levels. Explain how in each scenario the Fed would respond to the following: A decrease in velocity causes a downward shift on the aggregate demand. Prices are fixed in the short run meaning only output decreases. To ensure output and unemployment are at their natural rates Fed B should increase the money supply to attain the initial equilibrium where prices and output will be constant. Fed, A should also increase the money supply to shift the aggregate demand curve upwards since this is the only way to ensure stable prices at their original equilibrium. This results to an upward shift of the supply curve. To ensure stable prices, Fed B should hold aggregate demand constant since prices will rise in the short run and then fall in the long run achieving the natural rate of unemployment. This might however result to a recession. To keep output and unemployment at their natural rate Fed B should increase the money supply hence shift the aggregate demand curve upwards. This results to a new equilibrium at higher prices, but there is no loss in output. Based on the quantity equation MV=PY, if Fed reduces the money supply by 5% the aggregate demand curve will shift downwards. A decrease in M will hence result in a decrease in PY provided V is constant. In the short run, the assumption is that the price levels are fixed meaning that that the aggregate

History of CNC machines - Literature review Example Nowadays CNCs offer the capacity to connect to the internet. Companies having multi operations are benefitted a lot from this so that they can transfer their programmes to other locations. Today’s CNCs provide a very high level of automation. Any skillful operator can use all the features to increase his/her own as well as company’s productivity. Their capacity to deliver extreme precision has given a great boost to innumerable new state-of-the-art technologies as a multiplier effect to produce thousands of products in the last 30-40 years. 1. Introduction: â€Å"The world CNC is an acronym for Computer(ized) Numerical(ly) Control(led) machines used for the manufacturing of simple or complex parts from metal, wood and other materials by using the programme known as G-code.† (CNC- Definition). It all began with the creation of the worlds first digital electronic computer in 1945 by Dr. John Mauchly and Dr.J. Presper at the University of Pennsylvania. The device was called an electrical numerical integrator and calculator (ENIAC). It came into existence out of the need for faster scientific and engineers calculations required during World War II. It was not a programmable device but surely it was a first indication what the world is heading for in terms of computational and programming tools in later years. Before the advent of NC machines, operator had to manipulate the hand-wheels, levers, cams to make parts. This way the ability of the operator to make the parts with required narrow tolerance was limited. There were all possibilities of some variation resulting into variation of the axis dimensions resulting into poor fittings or wastages. The productivity of the worker was low so it was a dire need to operate the machine automatically. Earlier a series of cams were put to use to move the tools as an attempt to automate the process. Though they were tedious to set but once set it

Investigation on Rates of a Reaction Essay Example for Free

Investigation on Rates of a Reaction Essay We are changing the concentration of the acid solution to see which has a quicker reaction with the metal. To keep it a fair test I will be keeping the following constant:    The length of the magnesium   The volume of the acid The temperature of the solution and the laboratory in which we carry out the experiment I will not be using a catalyst Prediction Based on my scientific knowledge I predict that as the number moles in a solution (unit at which we measure concentration) increases the speed at which the reaction occurs will also therefore the higher the concentration the faster the reaction takes place. In this view by doubling the concentration theoretically the time taken should half. Apparatus Here is a list of equipment that I will be using during this experiment:    25 x test tubes 5 x test tube racks   500 ml x hydrochloric acid (HCl)   160 ml x distilled water   25 cm x magnesium ribbon (mg) 1 x medium beaker   1 x bung   1 x measuring cylinder   1 x scissors   1 x stop watch   1 x pencil, pen (to label the test tubes) and table for results Method Here is an account of how I will be doing the actual experiment (based on the pilot experiment). Collect the test tubes and place them in the racks, cut magnesium ribbon and collect the acid and distilled water, measure out the following:    20 ml of acid (2 moles of acid)   17. 5 ml of acid and 2. 5 ml of D. water (1. 75 moles )   15 ml of acid and 5 ml of D. water (1. 5 moles )   10 ml of acid and 10 ml of D. water (1. 0 moles ) 5 ml of acid and 15 ml of D. water (0. 5 moles ) Prepare each 5 times and pour into test tubes Use one rack per concentration.   Once each is measured place a bung in the starting test tube and shake vigorously to thoroughly mix the solution. Place one piece of magnesium ribbon into the solution and start the stop clock. Stop the clock once the solution has completely finished reacting (no bubbles are being produced) with the magnesium and record.   Repeat this for all 25 test tubes Calculate the average for each set of results Plot this on a graph NB. D. stands for distilled. In order to ensure that this experiment is safe I will be doing the following: Any bags must be placed securely under the desk.   The experiment must be performed in the centre of the table.   I will only add acid to water. We will be wearing safety goggles at all times. Towels and running water will be nearby in case of any acid spills. Ms Pinion will be supervising all of the experiments. Below shows a diagram whilst the experiment is being performed: Results Concentration (moles) Time for try 1 (secs) Time for try 2 (secs) Time for try 3 (secs) Time for try 4 (secs) Time for try 5 (secs) Average time (secs) 0 Analysis. Looking at the graph I can see that as the concentration increases the time taken for the reaction to occur decreases therefore the rate of reaction increases. As I said in my scientific knowledge this occurs because as the concentration increases obviously the number of particles within the solution also increases. With more particles the chances that the HCl molecules will collide with the magnesium molecules and have enough activation energy increases and so the rate of reaction will increase. You could also read the graph another way, as the time taken for the reaction to occur increases the concentration decreases. The reason behind this is that with fewer molecules of HCl in a weaker acid the fewer the chances that the particles will collide with the magnesium molecules and so the rate of reaction decreases. Between the concentrations 0. 5 moles and 1. 0 mole the line was quite steep; there was a rapid decrease in the time taken for the reaction to complete. A possible reason for this could be that 1. 0 moles is double 0. 5 moles and so because there is double the amount of molecules theoretically the time taken at 1 mole should be half of that taken at 0. 5 moles. My prediction was correct because as the concentration increased the time taken for the reaction to occur decreased therefore resulting in a higher rate of reaction. Evaluation Looking at my results I think that they are quite accurate, the graph is a smooth curve joining 4 out of the 5 points, I received one anomalous result. This was for 1. 5 moles, the result I got was 48 seconds when it should have been 32 seconds. A possible reason for the anomaly could be from the following:-   Too little acid was placed in the solution and so the concentration could have been less than originally expected. Human reaction time is always delayed and so the reaction may have stopped seconds earlier.   The equipment I used may not have been accurate enough, for example I used a measuring cylinder when I could have used a burette to measure the acid and the water.   I judged whether the reaction had finished by looking when it had stopped bubbling; obviously this can be difficult to keep accurate as it is not always easy to tell, in a slow reaction for example bubbles can be produced very slowly, if there is a large gap in time when no bubbles are produced I could assume that the reaction had stopped when it hadnt making the reaction unfair. To over come this, instead I could measure the amount of hydrogen produced in a certain amount of time; to do this I would need a gas syringe. I believe that I repeated my results a suitable amount of times to get a reliable average and I think that my range of results was enough to complete the investigation with suitable proof. Yet based on the information above I could say that the data may not be sufficiently accurate to support a conclusion, despite the fact that my results were as I had expected the question arises that if my results had have been more precise would my results have been different. My result didnt follow a specific pattern but they did decrease as I increased the concentration. If I were to develop this investigation further I would almost certainly repeat the experiment taking into account the information above (possible reasons for the anomalie), by doing this I will be able to establish the whether or not the investigation that I performed this time was inaccurate. If I were to explore other areas of this topic I would look at different metals and how they affect the rat of a reaction, different acids and see what effect they have and I would possibly look into one of the aspects of my scientific knowledge.

Treatment for Peri-Implant Diseases

Treatment for Peri-Implant Diseases Abstract Introduction: One of the substantial changes in dentistry is the development of implant science. Along with the development of applications, implant science practitioners will face an inevitable challenge which is how to deal with such problems. Recent conducted researches are more concentrated on surgical and prosthetic techniques, while the treatment for peri-implant diseases is still incomplete. Therefore, the aim of this review research is to provide a broad and descriptive overview on peri-implant diseases and to suggest the related treatments. Materials and Methods: Scientific articles were collected by electronic searching through EMBASE and Medline and since controlled clinical trials were limited in this field, no limitation was imposed on the evaluated articles. Moreover, review articles and meta-analysis were used. Results: For implants that bone resorption has affected less than 50% of the implant length, the evaluation is thoroughly recommended. Regarding cases with a range of less than 2mm, the treatment plan will be more inclined towards non-surgical methods and should be treated by Peri-implant mucositis. If the bone resorption is more than 2mm, surgical methods are proved to be more effective and in the cases which has extended more than 50% of the implant length, it is better to remove the implant. Conclusion: By increasing the range of annual dental implant, peri-implant diseases have become a serious challenge in this field. The proposed treatment plan will be a manual for dentists regarding on how to deal with implant problems; although further researches are required to approve the proposed protocols. Keywords: dental implant, disease, peri-implant inflammation. Introduction The success of an implant treatment is approved through various studies (1-4); however, further evaluation is needed on how to treat peri-implant diseases. One of the confirmed causes of dental implant failure is bacterial plaque along with extensive loading (5). Peri-implant diseases include non-specific inflammatory reactions that occur in host tissues (6-9); while the cases of inflammation in soft tissues are known as peri-implant mucositis, which is often considered a reversible reaction. Clinical characteristics of peri-implant mucositis include bleeding when being probed, peri-implant colitis, increase in probe depth (often as false pocket), or erythema and redness of the implant that surrounds tissues (10). It must be noted that symptoms are not necessarily limited to these cases. Moreover, when the inflammatory lesion strikes the bone, it is called peri-implant (11). Peri-implant is an irreversible process and bone resorption in radiography, bleeding, pus discharge during probe, increased pocket depth, ache, or fistula are among its characteristics (12). A loose implant is considered as a â€Å"failed implant† (12); while a â€Å"failing implant† is usually a progressive bone resorption with no looseness. It is a matter of the utmost importance to pay attention to practical differences of these two expressions. Dental implants may fail in various phases: Early failing: Occurs when the absence of initial osseointegeration is due to the inability of reaching the primary bone to implant contact. Factors that can be suggested in this case include early loading, surgical trauma, or incomplete/inappropriate healing response (such as patients with immune suppression, AIDS) (13, 14). Late failure: Happens after the initial integration of physiologic remodeling and loading. Bacterial infection and excessive loading are among the main factors in late failure (15). Failure due to the first year of loading is not prevalent (16). Ailing implant, also defined as peri-implant biological problems, is referred to the limited diseases of peri-implant’s soft tissue that do not affect the supporting bone tissues. On the other hand, loosing non-progressive connections and no looseness are its characteristics (17, 18). Peri-implant inflammatory processes are roughly similar to what happens around the tooth, except in the cases that peri-implant infections are initially less resistant to destruction due to the existence of periodontal ligament (19, 20). In other words, unlike the presence of fibers that are vertically placed around the tooth, peri-implant fibers are mostly parallel because of the absence of cementum. Moreover, the blood supply in peri-implant has been reduced in comparison with tooth (20). The aim of the present review article is to evaluate the causes of peri-implant diseases and its related treatment approaches. Materials and Methods: By electronic searching through EMBASE and Medline, the scientific articles were collected and since controlled clinical trials were limited in this field, no limitation has been imposed on the evaluated articles. Moreover, review articles and meta-analysis were used. Words like Mucositis peri-implant, treatment, peri-implantitis, and implant complications were used while searching for articles. Results: The prevalence of peri-implant diseases was often suggested by retrospective studies (21-23). Frasson et al. (24) indicated that more than 90 percent of peri-implant tissues have some inflammatory response. They have also reported 28% prevalence regarding the mentioned diseases. Roos-Jonsaker et al. (21) stated the prevalence of peri-implant mucositis as 48%, whereas 6.6% of implants have had the peri-implant. Generally, defining the prevalence of peri-implant diseases is slightly difficult due to the application of various protocols, different follow up periods, various implant systems, designs, and practical diameters. On the other hand, related information on implant placement area in terms of bone width and height or its position in mouth cavity is not fixed in various studies. It is said that, the primary cause of inflammation in peri-implant tissues is the resultant infection of anaerobic bacteria (25, 26). Initial evolution of periodontal pathogens in the biofilm of implant levels is reported in edentulous people (27) and it is similar to what has been identified in tooth (28-31). Periodontal pathogens could be colonized in implant level 14 days after mouth cavity exposition and a complicated sub-gingival microbial biomass will shape within 28 days after the implant exposition (32). Sato et al. (33) has clearly shown the presence of most periodontal pathogens in bone resorption cases compared with peri-implant mucositis. Peri- implant inflammation could lead to bone resorption and if it is not managed properly, it could cause implant loss. Furthermore, they illustrated in several cases that the existence of more than 5mm remnant pockets after the treatment of active periodontal disease can increase peri-implant and implant loss (34). This issue underline s the significance of accurate diagnosis in the initial phases of the disease and the necessity of appropriate and timely intervention. Managing and treating peri-implant diseases Controlling peri-implant diseases is a difficult and unpredictable process. One of the most important factors in their treatment is to evaluate implant looseness. The implant must be removed immediately if it comes loose during clinical check, after examining the possibility of abutment screw or prosthesis looseness (15, 18). This type of decision-making is in line with Pisa implant health test criterion, in which three groups are introduced as implants status (compromised success, failure, and satisfactory) (12). In this classification, failure is considered as a loose implant. Generally, looseness of the implant is the indicator of weakened BIC; therefore, a dentist must consider the situation as a criterion and instruction for deciding to whether keep the implant or not. Treating peri-implant mucositis When the implant is not loose, the next step is to identify the presence or range of bone resorption. If no resorption was detected, the diagnosis of peri-implant mucositis is highly probable, which is called Ailing implant (18). On the other hand, if the bone resorption has occurred, we would be facing a peri-implant, known as failing implant. Peri-implant diseases, including peri-implant mucositis, are infectious illnesses caused by Gram-negative pathogens in periodontal (35-37). Similar to the natural tooth, preventing the growth of biofilm and removing it from the implant must be the first phase in preserving the health of peri-implant soft tissue. Hence, treatment methods for peri-implant mucositis has nonsurgical basis and initially consist of mucosa and submucosa scaling. Synthetic treatments, including mechanical debridement and the application of non-microbial factors (such as chlorhexidineand essential oils), have been studied with caution to prevent damaging hemidesmosome joints at sulcus base and satisfactory results were obtained (38-40). However, most studies have proposed the use of antiseptics, the effects of topical antibiotic agents, and irrigation with antibiotics as supplementary treatments in mechanical debridement (41-43). The important point is that, studies have reported some significant advantages regarding the use of such agents in reducing index plaque. Schar et al. (44) indicated that the effect of nonsurgical treatments by photodyna mic therapy is similar to topical antibiotic; however, removing the whole inflammation has not been seen in treatment methods. Various surgical and synthetic methods were employed for surviving and treating ailing implant, which include debridement, decontamination of implant, and regenerative methods (45-52). Nevertheless, determining the best treatment method is not possible due to the variety of clinical conditions. Peri-implant treatment Peri-implant is considered as one of the main concerns in implant treatment. This obstacle is about peri-implant bone resorption with no looseness. For successful treatment of this problem, dentists must realize the range of bone resorption as their first step. Since the common two-dimensional radiographs have low sensitivity and cannot accurately identify the initial lesions (53), implants prognostic evaluations are limited through these diagnostic methods. On the other hand, the treatment of implants with bone resorption is unpredictable in any way, because the mechanical loading of these implants could endanger the long-lasting success (54). In the cases of bone resorption extending to more than 50% of the length, it is highly recommended to remove the implant and after the reconstruction of hard and soft tissues and obtaining acceptable results, it could be replaced in the area. Although these conditions are treatable by Guided Bone Regeneration (GBR), concerning the conducted re searches in this field to achieve this osseointegration is extremely difficult and unpredictable (55). For implants with less than 50% bone resorption, the case must be evaluated accurately. If the resorption is less than 2 mm, design is administered by nonsurgical methods, which is similar to peri-implant mucositis treatment. Nonsurgical treatments have been evaluated by different strategies (56-64). Mechanical debridement, regardless of the technique type, is not individually useful in removing the lesion and complete halting of peri-implant diseases (56). In other words, conducted studies on dogs, in which suture was the cause of disease, has shown favorable results in the form of reduction in periodontal pathogens (57), as well as improvement in clinical parameters such as probe depth reduction, adhesion improvement, bleeding on probe (58), and plaque index due to mechanical treatment. Synthetic treatments along with systemic antimicrobial (amoxicillin, metronidazole, tetracycline and clindamycin) (59) or topical antimicrobials (61, 62) (tetracycline fibers, minocycline microspheres and chlorhexidine gel) have shown a general reduction in number of pathogens and improvement of clinical parameters (index plaque, pocket depth, adhesion limit, and BOP). Laser is suggested as an alternative to mechanical debridement (64) and encouraging results has been reported; however, there is limited information on functionality, useful dosage, and probable effects on the bone, which indicates further research is needed. Consequently, it is worth mentioning that the obtained improvements is limited to clinical parameters and as published in various numbers of researches, not a single case has received the treatment completely. Accordingly, we cannot treat an advanced peri-implant through only nonsurgical method, expecting successful and predictable results. Exception can be made w hen bone resorption is limited and healing is facilitated by nonsurgical methods. Surgical methods are recommended when the bone resorption is more than 2 mm but has affected less than half of the implant length. Serino and Tutti (65) has stated that the success of surgical treatments in peri-implant diseases is related to the range of initial resorption. The employed peri-implant surgical methods is similar to the applied methods in periodontitis and the basic principles, including the removal of pathogens, are used in all the mentioned issues (25). If the aim of treatment is to preserve the bone, pushing the flap aside, similar to flap with apical position is performable (58). Regarding cases in which bone contour modification is considered, bone surgical methods are recommended. In surgical methods, the basic treating principles are the decontamination of infected implants (25). Nonetheless, retaining the integrity of the implant is a considerable challenge for clinicians. Variou s methods have been introduced for implants debridement. Favorable results were achieved in a study that chemical agents, such as metronidazole gel have been used as a flap (58). Although the range of the obtained bone remodeling is minimum, evidences were presented to prove the functionality of abrasive pumices by electric toothbrushes with rotational motion for the purpose of decontamination (66). The comparison of various debridement and decontamination methods, including Air-power abrasive, citric acid, normal saline, gas impregnated with chlorhexidine, or the combination of these methods, did not illustrate a significant difference in terms of bone regeneration and reintegration (67). According to a case report, using flap surgery ( along with decontamination by hydrogen peroxide ) with systemic antibiotic have caused an improvement in clinical parameter (Bleeding on probing) in long term and also halted the disease (68). Irrespective of implant decontamination methods (the com mon mechanical methods, chemical agents, Air-abrasive, laser, saline, and ultrasonic), flap surgery with implant decontamination is a treatment which improves and subsides inflammation, reconstructs the appropriate bone contour around implant, and halts the bone resorption. Bone respective surgeries around the contaminated implant (such as replacing implant levels, implantoplasty) can be performed along with respective surgeries for contour modification and bone anatomy. The obtained results indicated that, implantoplasty has the potential for more improvement compared to debridement with prescribing antibiotics(49). To provide remission and achieve health status in surrounding implant tissues, reintegration is vital and to reach that in a failing implant, various generative methods have been employed and different graft materials have been used to increase the range of BIC. Graft materials including xenografts, allografts, and alloplasts with/without membrane were used for this purpose (46, 47, 51, 69). These studies have shown the improvement of clinical and radiographic parameters as the reduction of probe depth and filling of lesion. There is no strong evidence in this field to support the usage of membrane, while in cases that membrane is used, its exposition is reported as a relatively common problem (66). Some studies proposed resorbable membranes to prevent exposure effects and reduce re-surgeries for removing non-resorbable membranes (51, 52). Currently, despite the lack of consensus on the privilege of a certain membrane, this is highly recommended. Dentists must carefully examine the c linical condition of patients and adopt the ideal treatment strategy based on the proposed methods. There are various methods to prevent the outbreak of disease around a implant, especially in patients with periodontal records, sensitive to peri-implant diseases, and more susceptible to colonization of pathogens (70-74). However, as long as the patient is in a good state of health and attends the follow-up sessions regularly, the issue is not a definite prescription for dental implants (75, 76). It must be noted that peri-implant soft tissue inflammation is possible, even in patients with no periodontal record as well. Accurate elimination and the removal of remnant infection is a prerequisite treatment, since the remaining teeth can act as a source of periodontal and bacterial pathogens. Early pathologic detection is a significant factor in preventing disease progress and long retention of dental implant health. It is worth mentioning that, the depth of peri-implant probing is not considered as a reliable method to check the health of a peri-implant (77) and radiographic evaluatio ns are important, as well. Therefore, peri-implant probing and probe depth enhancement are related to adhesion loss and bone resorption (78, 79), which could be a suitable method for evaluating the adhesion limit. It must be noted that, the accuracy of evaluation methods is a limitation and also, bitewing and peri-apical radiographs are helpful in this field (80). Consequently, a decision tree has been defined to control peri-implant diseases to be used as a manual (81-83). In order to treat and evaluate the peri-implant problems, long term and periodical clinical and radiograph evaluations, along with their comparison to the criteria are needed. Since peri-implantitis and periodontitis are not curable diseases and relapse is probable, longtime retention periods in patients to control and prevent is the matter of the utmost importance. Conclusion By the increase in number of annual implant replacements, peri-implant diseases has become a challenge. The proposed treatment in this project will be a manual for dentists to confront the issue. To confirm the provided protocols, further studies are required in this field.

The Nature of Evil in Shakespeares Macbeth Essay -- GCSE English Lite

Macbeth:   The Nature Of Evil   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In Macbeth, the character of Macbeth has a. firm and correct grasp of self-knowledge, and a well developed concept of the universe and his place in it. He willfully disregards his own moral thoughts and institutions. According to Bernard McElroy, "more than any other Shakespearean hero, he [Macbeth] has a perfectly clear concept of who he is and where he stands --- and it is exactly this perception that torments and spiritually destroys him"(330). Macbeth is strongly impelled to evil but he also abhors evil. It is this that causes Macbeth to abhor himself. The play explores the tensions between Macbeth's proneness to evil and his abhorrence to evil. Macbeth is a tragic hero because he becomes caught in tensions between his criminal actions and the reaction of his conscience. Had Macbeth committed the deeds without any remorse, he would have been simply an evil monster, without any hope. But it is his conscience about evil that makes him tragic. Through Ma cbeth's actions, Shakespeare is able to depict the nature of evil as being: lusftul, deceptive, tyrannical, and disruptive to family. To begin, Macbeth himself stands as a symbol for Satan's sin of ambition. Like Satan, Macbeth's insatiable lust for power and ambition drives him to commit evil. Although Macbeth's ambitiousness is not in itself evil: "His very strong social sense, worldly but valuable, together with that gift of imaginative expression whereby he far outshines all the others, makes him naturally and rightly desirous of winning `Golden Opinions from all sorts of people' [I.vii.33]" (Elliot, 288). However, Shakespeare asserts that Macbeth knows his place in nature, and is overly ambitious according to Calvinist doctrine ... ...d devoured by it. Works Cited Bethell, S.L.

Shakespeares Othello - Essay on Iago as the Hero of Othello? :: GCSE English Literature Coursework

Iago as the Hero of Othello?  Ã‚   In the play Othello, by Shakespeare, the character Iago is perceived to be a sinister and wicked individual to readers who have just read the novel. If people give more thought to Iago's character and the actions that he took in order to attain the things that he wanted, then they can find some admirable traits in him. There is not one character in the novel that is entirely good or entirely bad. Each character is complex in his/her own way. After reading this Shakespearean work of art, I found that if the reader wanted to find fault in everybody then they could. Does this make the characters villains? Maybe it makes the characters individuals who are subject to certain emotions and problems that up rise and occur during the struggle for power. From the start of this play, friction between characters was prevalent. What's a Shakespearean play without conflict of characters? In Act One of Scene One, Othello angered both Iago and Roderigo when a promotion was given to Cassio. In line nine of Act One, Scene One, Iago says, "In personal suit to make me his lieutenant, Off-capp'd to him." Iago wanted and even pleaded lieutenancy. When the reader learns of that, then the play starts to unfold. From this point on, Iago holds on to his anger and does several things to get back at Othello and everybody who is around him. In lines 36-38 of the same act and scene, Iago states "preferment goes by letter and affection, and not by old gradation, where each second stood heir to the first." By saying that, Iago showed that he took Othello's promotion to another person extremely offensive. Iago brushed the insult off of his shoulders and posed as if he had forgotten about it. He stated, "We cannot all be masters, nor all masters cannot be truly follow'd" (Act One, Scene One, Lines 44-45). A master was what Iago was determined to be. Iago was the character in the play that held the trust of an abundance of characters. How worthy of the trust was he though? He played games with everybody’s emotions. To a certain extent, the people who put trust into him are at fault also. Iago seldom told people things directly. He spoke of things happening in his dreams or assumptions that he made.

Belief Systems: Self Uniqueness Meets Religion

In noting one’s particular belief or belief system, it is important to establish that this system of beliefs must not necessarily collide with or fit into one of society’s major organized, historical, cultural, and traditional religions, such as Catholicism, Hinduism, Buddhism, or Islam.Every person’s unique belief system is different from person to person, even within these larger religious groups, and my own personal beliefs, although able to be described as religious, must not certainly be so described, as each person is definitely unique and learns about life and creates one’s beliefs based on a multitude of personal lifelong and complex experiences, sources, and associations.In addition to the uniqueness of belief varying from individual to individual based upon the differences in self and environment by which a person moves through life, there is also the element of mental assimilation and accommodation as an ongoing process which needs to be viewed in full consideration. If beliefs change based upon knowledge obtained or formed and events experienced, even also in the biology of the person, then the movement of a person through time and development must also be considered.No person, place, situation, or belief system is static, rather it evolves and morphs with the colorful variation and change of humanity on a grand scale as well as on an individual scale. The uniqueness and changeability of the universe from day to day lends insight into the uniqueness and changeability of personal views. This is not to say that there are not beliefs and truths which are more constant or reliable, however, one must be ready to adapt these more constant truths to modern human society, which is always in flux.One belief, out of the hundreds or thousands interrelating ones which I probably have, is the unnecessary nature of school and educational institutions in general. Although this belief may change in time, as of this moment, I see forced s chooling as being a ridiculous concept, as are all forced or mandatory activities which strip the individual of free choice.My belief in unschooling, best illustrated by John Holt’s theories and the Unschooling. info website, basically suggests that each person should be free to live and learn on one’s own terms, handing over the precious responsibility of self direction in education to parents and their children, and rightly stripping from the hands of the government and other agencies towing the line of forced education, learning, or belief structures.If one must characterize this belief of mine in unschooling as being religious in the sense that it is practiced or believed regularly, then it is right to acknowledge that my belief in and positive regard of unschooling has been fairly regular and constant for the past several years, and I find affirmation in the stories of other people who also share my beliefs. I subscribe to groups, learn from online resources, and mingle with individuals who share this belief system.The belief I have in unschooling is rooted primarily in my dissatisfaction with other people telling me what to do from day to day for so long in my life, the primary group of which were teachers and professors in schools and universities. Unschooling, to me, is the perfect way to live life and raise children, offering learning and education as a self owned right, protecting the basic right to freedom of thought, for oneself and one’s children.I aim to support and encourage myself and others in so far as possible striving to embrace beliefs, learning, and thinking as a basic right of human life from conception to death, taking the primary role of learner securely back into the realm of the individual and out of the hands of overlords. Unschooling family members support themselves and one another in lifelong learning which naturally springs forth from both random and purposeful self directed experiences and choices.There are no topics or subtopics or interrelated topics which cannot be learned from a huge variety of sources and in a huge variety of ways. In is well worth time for universities and schools to reconsiders the musts of their students and for individuals to recognize that learning is their right and under their own control.Perhaps testing for knowledge or job readiness is appropriate when working with others, however, a diploma or a degree is not necessarily an adequate mark of what is learned, nor is it an adequate mark of what knows in comparison to others without diplomas and degrees. Mostly, it proves one jumped through other people’s hoops and paid a lot of money. So far, I haven’t had any disadvantages to having this belief system, which, supposedly, could be termed as a religious belief, and the advantages are always new, evolving, and ever springing, it seems.Spending time with my children would be a benefit, as do traditional homeschooling mothers, learning and helpin g my children to learn on our own terms and in our own ways is certainly a benefit, and liberation of thought from the mechanical systems of education is also a great plus. The perceived downsides which other people may hold but which I do not share is that unschooling requires time and energy for parents of young children, unschooling prevents full time or out of home work for one or both parents, and parents are unqualified to help their own children to learn.In disputing these what I view to be false downsides, I have to claim the belief that I think spending time and energy on children is absolutely fabulous and to be cherished, that of course children need the constant or near constant presence of the mother or other caregiver and that families can choose to support and encourage this, and that parents are very much qualified to teach their own children. Who else should be the primary judges of what people think and belief, of how they live their lives?If government or the stat e is apt to be selected as the answer to that question, then we may very well kiss individuality and the right to personal thought goodbye and swirl into the darkness of force and socialism. The role of tradition in religion in general to keep a group of people together in what they do and how they do things, how they express their beliefs, primarily in God. Traditions in religion such as going to mass at church on Sunday are similar to the weekly unschooling groups of individuals and families at the park.People need community support in what they do and what they believe, on a very basic level, so that one doesn’t feel isolated and alone. Traditions are fairly regular ministrations of keeping beliefs and ideas alive through purposeful actions. The best thing that I can do in keeping alive the traditions of unschooling is to continue to be active within this society or culture of people, sharing my experiences and beliefs as regularly as necessary through purposeful actions w hich support and encourage my way of life.Contributing to groups through conversations and literature are ways in which I can stay connected, either in person or through the virtual online world. It is very important to know what the beliefs of others are, both to keep one’s mind open to new ideas as well as to diplomatically handle differences of opinion and belief when interacting with people who do not share all or most or even a few of the same beliefs as oneself does. It is very often that people differ in opinions and beliefs, and it would even be safe to assume that no two people on this Earth do in fact share all of the same beliefs.Having two identical minds on one planet seems near to impossible, given the varied and colorful lifestyles and experiences, places and regions, times and spaces, wherein one’s individual point of view springs forth. Although it can be difficult to interact with people who are strictly aligned with a highly structured and formal bel ief system, it can also be difficult to interact with people who are flip and find not much purpose in any beliefs whatsoever.To me, a good balance point is knowing what one believes, knowing that beliefs are flexible, and being able to converse on an appropriately calm level about any and all posed ideas with others, unless one wishes to opt out of the conversation or proposed idea, which is also quite ok.

Pierre Frankel in Moscow: Unfreezing Change Essay

The case describes the conundrum of Pierre Frankel, a devoted employee of H-IT which is a global IT company. He was sent to the Russian subsidiary of H-IT in Moscow, to improve the subsidiary’s performance and increase profitability. The environment that greeted Pierre on reaching the Moscow office is not at all welcoming: (i) Lebedev, who is the MD for the Russian subsidiary tried to hire a number two for himself but his move was rejected by the upper management. He knew that Pierre was the replacement and considers him a threat. (ii) The subsidiary’s 450 odd workforce considered Pierre as an outsider who is trying to bring with him a lot of structural changes and break the status quo. (iii) Many guidelines were in place, to ensure efficient functioning of the organization and were followed globally. But they were hardly ever implemented here, in the Russian subsidiary. (iv) The atmosphere that had been a result of Lebedev’s micromanagement discouraged teamwork and expression of new ideas. Not a single file could move from one desk to another without the knowledge of the MD. (v) All this can also be seen as a direct cultural implication of the disintegration of the Soviet Union in 1991, as a result of which, the â€Å"Trust, but verify† ideology had been instilled into the Russian way of thinking. Essentially, Frankel had to act as a change catalyst and unfreeze the current state of affairs at the Russian subsidiary. If he is able to change the status quo, he will be able to reveal the drawbacks of the current situation. This is necessary because if the Russians were to improve their ways, it was necessary for them to believe that change is needed. Some constructive steps that he took to learn the Russian ways were: (i) In the first few weeks, he met all the relevent leaders in the organization including the line of business leaders to learn more about the subsidiary’s operations and laying the ground work for change. (ii) He tried to get into the good books of Nadia Abramova, the head of HR and who was rumored to be very close to Lebedev. (iii) He tried to identify people who were open to learn and willing to change. (iv) He tried to hire a native Russian to assist him with his agenda for change. He was opposed by Lebedev in this endeavor but  Frankel managed to get some resumes with the help of Nadia Abramova. Suggested Solution: The priority areas identified by Frankel were: increasing business predictability, improve sales efficiency and focus on strategic internal processes. To bring about a change in the organization, he had to change the way the employees thought and worked. He had to make the work environment full of energy, collaboration and trust for each other. To bring about this, Frankel had to change himself because the Russians were not going to mould their ways at the command of an outsider. It was just how they had become culturally. To do this, Frankel was correct in looking to hire a Russian guy who could help him connect with the other employees better. He should then try and communicate with Lebedev with a clear-cut agenda and get him on board. Lebedev’s change of outlook is key if productivity is to be increased at H-IT’s Russian subsidiary, otherwise, his services can be done away with. However great his connections may be and however good his communication skills may be, if his management style is proving detrimental to the company, he is no good.

Analysis Of A Linear Accelerator

Analysis Of A Linear Accelerator Nowadays patient with cancer are treated by radiation, surgery, chemotherapy or with a combination of these options. The radiotherapy treatment unit used to deliver radiation to cancerous cells and tissues is the linear accelerator, also known as linac. The linear accelerator has been defined by Khan F. M. (2003) as a device that uses high-frequency electromagnetic waves to accelerate electrons, to high energies through a linear tube. The electron beam itself can be used for treating superficial toumors, or it can strike a target to produce x-rays for treating deep-seated toumors. The energy used for the radiotherapy treatment of deep situated tissues varies from 6-15 MV (photons) and the treatment of superficial toumors (less than 5cm deep) is between 6-20MeV. (Khan, 2003) The purpose of this essay is to describe a linear accelerator, analyse its components in the stand and the gantry of the linac, and explain the principles of operation and then discuss why it is best situated to the task for which it was designed. Some advantages and disadvantages of the linac will also be included in the discussion part of the essay. Main body: Figure 1:http://www.cerebromente.org.br/ As you can see from the schematic picture above, the major components of a linac are: Klystron: source of microwave power Electron gun: source of electrons. Waveguide (feed and accelerating waveguide): microwaves travel through the feed waveguide and then to the accelerating waveguide, where electrons are accelerated from the electron gun. Circulator: a device that prevents microwaves of being reflected back from the accelerator. Cooling water system: cools the components of the linac. Bending magnet: â€Å"A bending magnet is used to change the direction of the accelerated electron beam from horizontal to vertical.† (Hendee et al, 2005) X-ray target: electrons hit the target and produce x-rays. Flattening filter: even out the intensity of the beam. Ionisation chambers: they control th e dose leaving the head of the linac. Beam collimation: shape the radiation beam to a certain size Klystron: There are two types of microwave power. The klystron and the magnetron. Magnetrons are used for lower energy linacs. In the high energy linear accelerator klystron is used. All modern linacs have klystrons. Both klystron and magnetron are special types of evacuated tubes that are used to produce microwave power to accelerate electrons. (Karzmark and Morton, 1998). â€Å"The tube requires a low-power radiofrequency oscillator to supply radiofrequency power to the first cavity called the buncher.† (Hendee et al, 2005) In the bunching cavity, electrons produced from the electron gun, are bunched together to regulate their speed. The microwave frequency is thousands times higher than ordinary radio wave frequency. For a linac to work, the microwave frequency needed is 3 billion cycles per second. (3000MHz) (Karzmark and Morton, 1998) Electron gun: The electron gun is part of the klystron. Here, electrons are produced and then accelerated to radiofrequency cavities. The source of electrons is a directly heated filament made from tungsten, which will release electrons by thermionic emission. (Bomford, 2003) Tungsten is used because it is a good thermionic emitter with high atomic number, providing a good source of electrons. Klystrons usually have 3-5 cavities, used to bunch electrons together and increase microwave power amplification.
