Mary Wigman

Mary Wigman: Witch Dance Word Count: 1120 Through her simplification and breaking down of theatrical and aesthetic dance, Mary Wigman stands as one of the most inspirational figures of 20th century dance. Her unique use of theatrical elements such as masks, sound, costume and movement created an evolution of dance that was never seen before. Her use of the character, The Witch, changed the world’s views on dance forever, and inspired a revolution of artistic quality all around Europe.In this essay I will discuss whether or not The Witch in Wigmans work stands as an interpretation of her role in society, and her aspirations for future dance forms. Mary Wigman’s Witch Dance epitomized the breaking away from conventional concepts and traditions. Through her modernistic choreography she captured the true essence of dance. There was no conformity or theatricality to it. Instead, she used elements that would speak directly to the audience (Muller, 1986, pp. 173-184). The arch aic image of the witch expressed the elements of Wigman’s own identity.She expresses her modernistic identity in her breaking away of the social and cultural boundaries that besieged her time error. She also physically identifies herself as a witch, absorbing the viewer with the magical essence of her imagination. Through her movements she was able to personify this strong presence of the witch (Gunhild, 1992, pp. 35-49). She stressed the common association of the image of a witch with that of fear and apprehension of losing control over both body and mind.This fear was created to be extended to the audiences watching the piece (Chritiane & Finnan, 2006, pp. 76-84). One of Wigman’s most praised techniques in dance was her use of breathing. She believed that a dancers expression could be built to a climax simply through the pace and tone of their breathing. Through inhalation and exhalation the dancers were able to create both tension and tranquility. In addition to thi s her dance techniques were also highly revolutionary.Wigman did not believe that dance should be performed merely for entertainment purposes (Chritiane & Finnan, 2006, pp. 76-84). She diverged herself from the conventional practices of dance, such as ballet, and formed her own unique dance language that stripped away the aesthetic movement that was generally accepted at the time. The movement which she used in her pieces was unrestricted and she made use of percussion instead of traditionally orchestrated aesthetic music (Muller, 1986, pp. 173-184).This made the audience focus more on the properties of the dance itself then the external features of it. Wigman’s dances hypnotized the viewer with its powerful yet highly abstract choreography. Her use of repetitive gestures in her choreography helped to carve their cultural roles. She broke away from conventions by pulling away from the aesthetics of ballet. She did this by avoiding following fixed choreography, dancing barefoo t and using eccentric music and percussion (Gunhild, 1992, pp. 35-49).The cultural context in which Mary Wigman’s lived was a very restricted and conservative society. Wigman grew up in Germany during the Weimer republic. This was a time of extreme change in Germany. Ausdruckstanz had been ubiquitous in Germany from the start of the 20th century, and there was a definite cultural and social revolution taking place. Along with this was the reign of feminism taking place worldwide. These ideologies and social changes showed up significantly in Wigman’s choreography. Before Wigman, dance was primarily based on sexuality (Jiyun, 2007, pp. 27-437). Exoticism was instrumental in the audiences appeal to it. Wigman broke away from these ideals by performing characters which held modernistic significance (Muller, 1986, pp. 173-184). Before Wigman, women were often portrayed in dance as modest and simple characters. Wigman changed this view by primarily using female dancers and depicting females as strong and powerful beings. Wigman’s performances challenged the static social dynamics of the time. She created an atmosphere of respect between the female dancers and herself.She allowed for a strong female subject in her pieces that provided females, who were previously oppressed, with a firm identity and place in society. Previously, male choreographers had objectified woman in their choreography. Wigman aimed at individualizing women and breaking away from the sensual image that they previously conformed to (Valerie & Lahusen, 1990, pp. 8-10). Wigman’s choice of using the witch figure in her choreography was partly influenced by her attempt to emphasize the roots of dance and highlight feminist ideals.Through her dances she strove to elevate her art to a new culture and change her own identity to that of a goddess. The witch figure stood as a solution to the concept of Ausdruckstanz (Valerie, 1998, pp. 298-304). This concept introduced a confl iction between the desire to have their dance accepted by society but maintain a strong level of originality at the same time. Wigman’s dance focused primarily on raw and natural movement to truly capture the fresh expressiveness of her work.Through her work she hoped to portray a new vision of life. She wanted her work to be characterized by its dark and somewhat masculine nature. She explored the different ways in which the body could express itself (Valerie & Lahusen, 1990, pp. 8-10). She tried to use freedom of movement in expressing her sensuality and accepted that improvisation was the first step toward composition. The important thing about Wigman’s choreography was that even those who misunderstood it were inspired by the energy of her performances.The audience seldom failed to recognize the energy and life in Wigman’s choreography (Gunhild, 1992, pp. 35-49). The witch in Wigmans choreography represented the overcoming of human mortality and deficiencies through her new religion of dance. The dances were not sets of beautifully displayed images, but were created through disfigured movement that held no consideration for the viewer’s enjoyment. She ripped the space apart through her dance and engaged in the emptiness and diversity of the space.In conclusion, Wigman played a truly inspirational role in the modernization of dance in the 20th century. It would seem that Kolb’s statement regarding the feminist and demonic quality would be true with regards to the time error that she found herself in. The Witch not only represented woman as a powerful figure, but it highlighted the abstract quality of her dance. Wigman changed the face of dance forever through her diverse and unconventional ways of thinking. The way she broke away from conformist ideals still serves as inspiration to the dance we have today.

Patriots in Lower Canada

Quebec is known as the homeland of the French-speaking Canadians. Its uniqueness in culture was guaranteed by the British North American Act and is a cornerstone of Confederation. Prime Minister Pearson encouraged and advertised the idea of making the Canada as a homeland for French-Canadians and not merely for the Quebec. 1 In 1837, both Upper and Lower Canada had their rebellion opposing the proposed union between the two halves of Canada.The Canadian Patriots who are the Quebecers would like to separate from the British colonialism and led themselves in any affair which for their own benefits. This rebellion was not materialized and there were twelve Patriots in Lower Canada who were put to death and hung in Montreal. Aside from that, there were sixty patriots who were exiled to Australia. In Upper Canada’s case, the rebels who had rebellion were also sent to Australia. After this incident, the Durham report came out and tried to have solutions for the French-Canadian feud. 2 According to Claude Belanger that Durham suggested the â€Å"joining of the Upper and Lower Canada into one legislative union having two administrations to institute responsible government as to remove a major source of friction that had existed between the government and elected officials prior 1837 to assimilate the French†. 3 _______________________ 1.

It was able to analyze the root causes of rebellions. Durham’s report has four main topics; these are the causes of conflict in Upper Canada, causes of conflict in Lower Canada, the Union of the Canadas and responsible government. 4 The earl of Durham whose name was John George Lambton introduced the Durham r eport to the Colonial Office in February 4, 1839 but Durham report was consummated in January 1839 that was why it was officially introduced in the following month by the said earl of Durham.5 After the rebellion in 1837, earl John George Lampton was designated as governor general of British North America with special power as lord high commissioner6 to inspect colonial grievances. He arrived in the spring of 1838 in Quebec. The report of earl John George Lampton called â€Å"Report on the Affairs of British North America† was one of the most significant documents in the British Empire history. 7 The report on the affairs of British North America made by Durham report suggested reforms as the creation of municipal governments and a supreme court.According to David Mills on his website that Durham condemned the â€Å"defective constitutional system in Upper Canada where power was monopolized by a petty, corrupt, insolent Tory clique†. Durham was able to narrate the dile mmas as racial and not political based in Lower Canada. He was able to found out that there were two nations fighting in the heart of one state. 8 __________________________ 4.

Durham suggested the assimilation of the French Canadians through the legislative union of the Canada to secure harmony and progress9 which they have had between 1791 and 1837. 10 This report of Durham was favored by the reformers in UC and NS which in favored the idea of responsible government but was not accepted by the Upper Canada’s Tory elite. The Montreal Tories showed their support to the union for having a reason of finding it as a way of overcoming the French Canadian opposition for the ir plans in economic development . 11Durham report was mistakenly perceived about its suggestion in assimilating the French Canadians that it came from an intolerant, racist attitude. Durham had his three reasons why he suggested assimilation. The following reasons of Durham report are taken from Claude Belanger: â€Å"*There was, for a variety of reasons, some of which disclose intolerance on the part of Durham, a deadly animosity between the English and the French and this made efficient government of the province impossible. *One should consider who will dominate eventually on this continent; the French of Canada will suffer the fate of the Acadians of Louisiana.If the French cling to their ancestral ways and language, in a continent increasingly dominated by the English, they will put increasingly in a position of hopeless economic and social inferiority. *Because they are French, a spirit of __________________________ 8.

He has one significant mistake of judgment when he stated that the French-speaking Canadians might be influenced by a growing English-speaking majority. 14 When Earl John George Lampton was in Quebec for his few months of staying there, he was busy gathering information which was needed for his report. On the other hand, he was attacked by his political opponents at his own homeland and received great criticism from them.15 After few months of investigation, Earl John George Lampton was able to go home, England, to give his findings about the dilemmas in Canada. He was not able to witness the action that was taken according by his report because he was ill and died after. 16 But indeed, Durham report was able to played a significant role in the progress of Canadian autonomy. 17   12.

Macbeth Act 2 Scene 2 Essay

I shall now evaluate the significance of Act 2 Scene 2. Before this scene we know that Macbeth has already killed King Duncan. We have been introduced to Macbeth and Lady Macbeth. Furthermore, we have been introduced to the Murder, and guilt in the environment. This scene is essential to the plot because the scene produces and develops the character of Macbeth, and shows a different side of Macbeth after the murder of Duncan. It is essential also because it shows the reaction and effect the murder has put on Lady Macbeth. The two main characters in this scene are Macbeth and his wife, Lady Macbeth. This scene is one of the most significant scenes in this entire play. Owing to the fact that, in this scene Macbeth and Lady Macbeth reveal their equivocating and uncertain emotions and personalities. To be precise, in the beginning of this play Macbeth was a courageous, honourable and loyal soldier. However, he met three witches after a war. The witches sabotaged his mind into believing the fact that he would become the King of Scotland. These predictions the witches made roused Macbeth’s ambition and lead him into murdering King Duncan. In this scene, Macbeth has been mocked by his wife, into killing Duncan. Confused with his conscience and ambition Macbeth commits the sin. This scene shows the changes in Macbeth’s emotions and specifies that he is an enterprising character, who goes through the contrast between his courage and guilt. Act 2 scene 2 shows that Macbeth is in misery. This scene is about Macbeth being questioned by his conscience and about the betrayal that he has committed. An example of Macbeth questioning his conscience would be: â€Å"But wherefore could not I pronounce â€Å"Amen†?† In this quote you can tell that Macbeth is asking himself a question that is connected to him being uncomfortable. Another example of Macbeth’s guilt is: â€Å"Methought I heard a voice cry ‘Sleep no more!† This quote proves that Macbeth knows that he won’t be able to sleep at night, because his conscience has been questioned.  Act 2 scene 2 portrays Lady Macbeth as a cruel and evil character. The fact that she says â€Å"That which hath made them drunk hath made be bold† shows that she doesn’t feel any guilt and that she is still very cruel instead of being worrying about the consequences about the things that she has done. When  Lady Macbeth says â€Å"Why did you bring these daggers from the place? They must lie there: go carry then; and smear the sleepy grooms with blood† you can tell that she is only afraid about getting caught, but not guilty about what he has done, except she wants to make it seem even worse by smearing the grooms with blood. Shakespeare emphasizes the two character’s personalities by making them completely different from each other. He makes it a balance because he wants the audience to see the irony that he has created in the play because in the future the two characters will swap their personalities.  Shakespeare uses the effect of imagery in this play. In this particular scene he uses his strong visual words to create pictures in the audience’s minds. Even though, the death of Duncan isn’t described specifically in this play, the audience will still be able to imagine the terrible scene of murder. When Lady Macbeth says, â€Å"My hands are of your colour; but I shame to wear a heart so white† she implies the effect and image of blood, because when she says colour people will most probably think of blood. Macbeth responds by saying â€Å"This is a sorry sight† it also implies to the audience that it isn’t very good to be seen. Also, when Lady Macbeth says, â€Å"Smear the sleepy grooms with blood† the imagery is very effective because people can picture a room and people smeared with blood. Imagery is very significant because it is the only way that the audience will be able to see the story. If there are no strong visual words then the audience will not be able to see anything, this way it will be harder for the audience to enjoy the story. Hence, Shakespeare uses imagery. Murder and guilt are the two main themes addressed in this scene. In the whole play, Macbeth’s unintelligent behaviour and other flaws in his character caused Macbeth’s failure and ruination. Also, Lady Macbeth’s pressure on him was an important reason of his downfall. This is shown comprehensively in this scene. In this play Shakespeare is trying to show the audience that ambition and passion is good only when it is thought up to a limit, and if people think of right and wrong. However, it could be bad when it becomes so passionate that it shatters one’s honour and pride. In this scene Shakespeare tries to show the audience Macbeth’s wrong decision and the consequence to his spurious ambition. The theme of murder is shown in Lady Macbeth’s dialogues. When she says â€Å"I have drugged their possets† the audience can feel the murder theme, because Lady Macbeth is so keen and excited about Duncan’s death that she would do anything. Also, when she says â€Å"Had he not resembled my father as he slept, I had done’t† it also shows that she would have done anything to make Macbeth the king. The theme of guilt is only shown in Macbeth’s dialogues. When Macbeth says â€Å"Sleep no more, Macbeth shall sleep no more† the audience can easily tell that Macbeth is feeling guilty about what he has done. Also, when he says â€Å"This is a sorry sight† people can tell that Macbeth is afraid of what has happened. Also, the audience can tell that Macbeth hasn’t done everything with his own decision. This is very ironic because in this scene Macbeth is the one who is guilty and carries on with the theme of guilt. However, further in the play it’s Lady Macbeth that is guilty and Macbeth carries the theme of Murder instead of Lady Macbeth. The original audience would have responded to this scene with fear and anger towards Lady Macbeth because she plays a very cruel character that is very vicious and nasty and doesn’t care about what has happened. However, the audience would feel sorry for Macbeth and find Macbeth very dumb for doing what he has done. The overall dramatic impact of the scene is a very strong effect of evilness. The most intense aspect of this scene is when Shakespeare shows the difference between cruelty (Lady Macbeth) and guilt (Macbeth) because this is the point where the audience is thinking most about the reaction of characters of the death. This scene is a scene of a climax point where there are a lot of different characteristics added to each character. The scene’s significance to the rest of the play is very strong because it is contrasting to the rest of the play where Lady Macbeth becomes guilty and Macbeth becomes vicious.

Martin luther king jr - Research Paper Example This is also the case with his experiences in different regions of the African world, and of his successes and efforts in support of African emancipation.2 These experiences and efforts influenced King’s ideas of racial circumstances in the United States in reflective and philosophical ways, and they reveal a connection between King and the pervasive attention given to Africa and matters related to being African among blacks since the latter part of the 1960s. The thoughts and influence of King on Africans and the issue of African Diaspora is the focus of this research paper. A great deal of emphasis is given on King’s appreciation of ties and responsibilities between individuals of African lineage far and wide, and on his influences on the fight for African emancipation and self-determination. The pro-independence components in King’s ideas were conclusively shown in those areas of his oral and written works wherein he concentrated on particular issues confronte d by individuals of African lineage all over the globe.3 His emphasis on the situation of his fellow Africans in the U.S. has been widely studied and well documented. King articulated a profound concern for Africa’s fight against colonialism and racial discrimination. He proclaimed in 1956, â€Å"We could turn our eyes to Africa and notice there two hundred million black men and women under the pressing yoke of the British, the Dutch and the French. For years all of these people were dominated politically, exploited economically, segregated and humiliated†.4 King proclaimed a year afterward that â€Å"you also know that for years and for centuries Africa has been one of the most exploited continents in the history of the world†--- â€Å"the continent that has suffered all of the pain and affliction that could be mustered up by other nations†.5 King believes that the mistreatment and coercion imposed on Africa over the years were most apparent in the slave trade, which plundered West Africa’s Gold Coast. He also emphasized that the misuse and abuse of Africa by the white civilizations persisted until the 20th century, inhibiting not just the progress and expansion of West Africa, but the Union of South Africa and other areas of eastern, southern, and northern Africa.6 King’s perception of the African situation in general pushed him to believe in 1959 that â€Å"It is impossible for Angola to stand in Africa and not be affected by what is happening in Nigeria and Kenya and Rhodesia.†7 The interest of King in Africa was widely expressed in a variety of ways. In 1957, he positively responded to a private request from Prime Minister Kwane Nkrumah of Ghana to see the liberation of the Gold Coast. King’s wife, who accompanied him in the trip, portrayed the invitation of Nkrumah as â€Å"one of the most exciting things that happened to us,†8 and stressed that the prime minister â€Å"knew America well and had invited a number of outstanding American Negroes to share Ghana’s great day.†9 King also talked about the significance of the invitation of Nkrumah, arguing that it was an encouraging assertion of the Montgomery struggle and of the bonds that were forged between the Gold Coast and African Americans. The visit to Ghana, which is described in numerous documents as the â€Å"King’s first sojourn on the continent of his fathers†

Developing an effective classroom management plan Essay

Developing an effective classroom management plan - Essay Example A positive learning environment can only be created when this philosophy is kept in mind. At the basic level, a classroom simply comprises of a teacher and a group of students. However, a classroom cannot exist in isolation; it comes under the control of a school. Similarly, a school is also required to report to district authorities. Hence, there are multiple stakeholders acting together in this case and each has their own role to play. The role of each of these should be defined in way which maximizes the exchange of knowledge, and creates and maintains the learning environment. Moreover, these roles should also be used as the rules in effectively maintaining a positive learning environment in a K-12 classroom. Let us consider the roles and responsibilities for each of the members one by one. Teachers play the central role in a classroom. A teacher is the one who controls the entire class and it is his skills and capabilities which play a vital role in the learning environment of the class. In some cases, the teacher is the primary source of knowledge who communicates this knowledge to the students. In some cases, the teacher is merely a facilitator who assists the students in acquiring knowledge from textbooks. However, in any case, the role of teacher is indispensible. The role of the teacher should be defined in a way that he is able to effectively communicate with the students and interact with them. It should not be a merely one-sided communication, but the students should respond back. Hence, it is important that the teacher thoroughly knows what he is teaching. He should know all aspects of the topic and should be ready to answer any questions from the students relevant to the topic. Another important role of a teacher is to reward the students for their good perf ormance and punish the students for poor performance. This serves to improve the motivation of students towards the class. Moreover, he should make use of the tools and equipments, such

Analysis of the individual causes of the problem on the production Essay

Analysis of the individual causes of the problem on the production system of Toyota - Essay Example Toyota is one of the best known automobile manufacturing companies in the world. Toyota however went into crises last year due to some technical problems that are related to its operations management systems.Two million cars were recalled because of defects. The defects have been traced to the production lines and the company has announced that the problem can be solved if cars with defects are sent for repairs with authorized dealers.So far, 77 complaints have been lodged in the Japan and about 100 in the United States. About 7 different brands are due for mass recall in Mexico as well. There have been mass recalls of some of the cars that are affected by these defects.The defects are related to accelerator pedals and out of position floor mats. This causes the accelerator system to jam and leads to overspeeding which can and have caused accidents in Japan, United States and Mexico. Preliminary research has shown that the overspeeding does not happen suddenly but gradually, and it i s not connected to the electronic systems of the affected cars. Clearly, the problem with these defective Toyota cars can be traced to the production systems of the manufacture of these cars. This research is a proposal on a diagnostic system for the analysis of the operations management system of the defective cars and a diagnosis of the source of the problems in the manufacturing system. The aim of the research is the diagnose and identify the cause of the defects in the Toyota cars affected by the accelerator system problems. ... Objectives: The objectives of the research is to: 1. Examine the normal manufacturing and quality control systems used by Toyota in the United States, Japan and Mexico (the affected countries of the problem). 2. Analysis of the research, design and manufacturing lapses that are responsible for the accelerator defects in the cars in question and the failure of quality control to detect the problems. 3. The scope of the problem and future implications of these problems in the production line of Toyota and analysis of best way of solving the problems at hand. Literature Review The case of Toyota indicates that there were numerous levels of problems and challenges that hit the company. Hiles (2011 p582) gives a series of empirical evidence that is collated from the Kelley Blue Book Survey which shows the impact of the recalls on various levels to Toyota. These affected the customers, suppliers, the worth of vehicles and dealers. Competitors also increased interest in their brands due to Toyota's lapses. Although one might be tempted to think that the problem of Toyota was mainly an Operations Management problem, these outstanding statistics and facts show that the problem had a knock-on effect on the various stakeholder interests of Toyota. This is because the nature of the car manufacturing industry is such that the engineering systems and operations are at the core of the activities of a given entity. And due to the potential fatal effect of any mistake or error in manufacturing, a car manufacturer needs to take care to ensure that the best is done to ensure that cars parts and assembling lines do the right thing to prevent defects. Thus the scope of the problem and any effort to rectify it will mean correcting the lapses in the operations of Toyota and

Why did President Lyndon Johnson decide to send combat troops to Essay

Why did President Lyndon Johnson decide to send combat troops to Vietnam in 1965 - Essay Example Because it served as a buffer against the further spread of communism in the region, the West, especially the United States made serious efforts in supporting the South. However, South Vietnam’s government apparently failed in living up to the expectations of its people when it comes to uplifting them from poverty and landlessness. In the midst of worse economic disparities between the government bureaucrats and the majority of the people, the National Liberation Front or the Viet Cong began to advance an insurgency with ample support from the North. During the term of Pres. John F. Kennedy, the policy of the U.S. was still that of extreme caution. In treating the Vietnam issue, the Kennedy administration practiced the minimum requirement of the policy of containment, which is to provide logistical support and training to the South Vietnamese Army in order to make it capable in fighting the Viet Cong. By the time of his death, Kennedy had already sent more than 15,000 U.S. mil itary advisors to Vietnam. Even with the presence of that many troops already in a foreign country, the demand for more continued to rise as South Vietnam’s security problems continued to grow worse. ... Just like his predecessors, it was obvious that Johnson was very concerned with how one piece of the domino is about to fall, South Vietnam. It was the domino theory that inspired Kennedy to let the U.S. take an active role in South Vietnam by providing advisors and war materiel to the South Vietnamese Army. It was also this theory that would eventually prompt Johnson to send ground troops to the country. However, the orientation of the large numbers of U.S. troops sent to South Vietnam was not really to strike at the most potential source of support for the insurgency, which is the North. Although the ground troops were utilized to hit the local insurgents, the Viet Cong, they were instructed to take defensive posture against the North Vietnamese Army. This was apparently guided by a political and military response to the domino effect: containment. Containment is essentially defensive posture against the further spread of communism. For politicians who would not want to be labeled as too soft on the communists and who also do not wish to be considered as militarists or hawks, standing for policy of containment would seem to be the viable option. Pres. Johnson was an advocate of containment and this could be seen in the years immediately after he took over when Kennedy died. This policy, however, was constantly criticized by the political right in the U.S. as a sign of weakness, or of the unwillingness to venture into an escalated war that would achieve a quick and decisive victory against the enemy. Johnson defended his policy of containment well during the 1964 elections. His rival, Sen. Barry Goldwater often raised the issue of Vietnam just to portray him as a weak president at a time when the U.S.

Muslims and Americans Essay Example | Topics and Well Written Essays - 2000 words

Muslims and Americans - Essay Example That day, though I doubted people knew what I was going to do, I was still shaking as I was carrying a black bag and on my chest with a bomb inside. I was trying to hide it by crossing my arms over my chest. I started to worry. It seemed to me that the police were still coming for me. When the airport announced my flight, I went to the check into the gate. After that, I was trying to get the bomb out of my bag really quickly. Then, the police attacked me. The police caught me before I destroyed the airport and killed everyone. Unfortunately, I was trying to bomb the airport to help Muslim people and finally put an end to discrimination. I am a terrorist. People like me were built to destroy. Most people are afraid of me because I really look bloodthirsty. I am savage because everything that is taken away from me will surely have to face a bitter revenge from me. When someone steals anything from me, I try to cut off the thief’s hand immediately without any remorse. Also, everybody knows that I hate women because I really do not like to look at them. I do not treat women the same way that I treat men because I am better than all of them. I have high regard for religion. I do not drink alcohol because it does not suit my palate, and I am smarter than people who drink alcohol. Also, I do not eat pork because I think that pork is damned meat. All these written above would exactly be how Americans would write about my life today. But the truth is, I am not a single thing mentioned above. I am a young Muslim. I do not kill people, I have very close American friends, and have never done anything to hurt anyone. I do not drink alcohol or eat pork, and I respect all kind of people just like how I want to be respected. I have been living in the U.S. for two years, and I observed that most Americans think that all Saudi Muslims are terrorists. This is one of the dumbest things about Americans.

The Great Gatsby Essay Example for Free

The Great Gatsby Essay Throughout the novel The Great Gatsby there are several symbolic meanings of colours that Fitzgerald has incorporated. Specific colours in the novel contrast several different meanings and representations. Yellow is one colour in the book that Fitzgerald has incorporated for many reasons. The main representation of the colour yellow in the book is death. Death contrasted in yellow has been a main factor during the novel as in the end, basically the only yellow thing that has not been a part of death was Daisy. For example, George Wilson’s home in the valley of ashes is made of yellow brick and is the place where George and Myrtle live. Their house represents death in multiple ways as it was right outside of their house where tom and Daisy hit Myrtle and killed her. It was also the place where tom had told George that it was Gatsby’s car that had struck Myrtle, which resulted in him shooting Gatsby. Also, Gatsby’s yellow car is symbolic of death as it hits Myrtle when she runs out into the road. Lastly, nearing the end of the novel when Gatsby is in his pool, and quote the chauffeur asked him if he needed help, but he shook his head and in a moment disappeared among the yellowing trees. The yellowing trees represent death because the colour was a sign of alert which Gatsby did not realise. Also, because just as the Chauffeur disappeared â€Å"among the yellowing trees†, so did Gatsby’s life when shortly after getting in the pool, he was shot by George and killed. Yellow today represents caution just like a street light which turns yellow, which indicates caution to slow down. In the novel Fitzgerald is indicating that money and wealth cannot solve your problems. Throughout the novel Tom, Daisy and Gatsby get themselves into a lot of issues and think that their money can resolve their problems as evident from the previous examples, it cannot. Another symbolic colour that Fitzgerald has incorporated is the colour gold. Gold represents wealth. Throughout the novel wealth has been represented in several different ways. As Gatsby lives in west egg, he represents new wealth, and as tom and daisy live in east egg, they represent old wealth. Gatsby wants to be rich with old wealth so he can win the affection of his true love, so he buys a yellow car. But daisy did not want to give up the life and money that tom had, Gatsby did not have old wealth. Jordan and Daisy are represented by gold throughout the novel as quote Jordan’s slender golden arm resting in mine and high in the white palace the king`s daughter, the golden girl. The golden girl is of course Daisy. New money, which Gatsby has, represents more of the colour yellow which is why Daisy will not get back together with him. Gatsby tries to show daisy that he represents wealth several times during the novel by his appearance when quote Gatsby in a white flannel suit, silver shirt, and gold-colored tie hurried in. Also, Gatsby`s parties where quote turkeys bewitched to a dark gold. Gatsbys effort to impress daisy throughout the novel represents his love for her but daisy only cares about money and realised that tom is more wealthy. Throughout the novel, there have been many symbolic representations of the colour blue as well. The colour blue represents loyalty, patience, love, and the sky. For example, as blue represents loyalty, ironically tom is the opposite if loyal. For example, tom takes his blue car to the Valley of ashes to go have affairs with myrtle, as well he is a racist. Also, although blue can represent love, it can also represent sadness and unhappiness as seen through the relationship of tom and Daisy. As Daisy is â€Å"the Golden Girl† she sets her relationship with tom based on money instead of love, which proves to us that their relationship is undoubtedly blue. I also believe that blue is symbolic of patience and dreams because the blue lake is the separation between Gatsby’s house and Daisy’s house and one day he dreams of reuniting with her. As well Gatsby’s blue garden represents patience because every Saturday when Gatsby holds his elegant parties, he hopes that one day daisy will come to one, and just like nick and Jordan first met Gatsby in his backyard which is located by the blue garden, he hopes that he will find Daisy there as well. Finally, the eyes of Doctor T. J. Eckleburg. Eckleburg’s eyes represent the sky, as they are the colour of the sky, as well the connection between the eyes and god only exists only in George Wilson’s mind. I feel that blue today represents unending possibilities, which is what Fitzgerald had incorporated throughout this novel as the reader was never sure of what was going to happen between tom and daisy, Gatsby and daisy, as there could have been the possibility that Gatsby and daisy would get married.

Mobile Sensor Network for Indoor Environment

Mobile Sensor Network for Indoor Environment 4 node sensor network without collisions. Update of every sensor reading in the network at least once per second (available from all nodes). Single frequency channel (i.e. no frequency multiplexing permitted). Error checking (CRC) included to ( Measure at least 2 parameters (e.g. temp, light..) Data presented on serial I/O port in a format that is easily readable on a text terminal. 1. Background knowledge 1.1. System structure The aim of this coursework is to design a mobile sensor network for an indoor environment, communicating with a 2.4 GHz wireless link (IEEE 802.15.4). All the sensor nodes can realize data link, which means each board can get others information. All the sensor boards have the function of receiver link to the computer, and can present the sensor data (for all nodes in the network) to the serial I/O port in a format which is easily to be understand on a text terminal. If the nod which connected to pc is broken, the other 3 nodes can replace it and realize the function of receiver. Each sensor node will include a number of sensors interfaced to a microprocessor (for our group temperature, sounds, touch and light). The microprocessor will gather sensor data, communicate with other sensor nodes via a wireless transceiver, implement a network protocol and provide a PC interface via a serial I/O port for data display. The structure of whole system is as follow: Figure 1 Architecture of Wireless Sensor Network 1.2. Basic hardware The principle hardware used in this project is the PICDEM Z [3] development board from Microchip Technology Inc. There is a PIC18F4620 microcontroller on every node board and every group has 4 board available. The PICDEM Z has a prototyping area which must not be used for circuit construction. First, we need veroboard to construct a circuit, then interface it to the header J6. The next figure shows the structure of the board. Figure 1 The structure of the board And we also have other devices can use in this course: 1. 9V DC power socket (J1) for operation from mains adaptor. 2. 9V battery terminal (BT1) for mobile operation. 3. ICD connector (J5) for connection to MPLAB ICD3 in-system programmer/debugger cable. 4. RS232 serial port connector (P1) for connection to PC COM port. 5. Microchip MRF24J40 2.4GHz transceiver module connected to J2. 6. LEDS RA0 and RA1 for indication. 7. Push buttons RB4 and RB5 for simple logic input. 8. Header J6 giving access to analog and digital I/O pins Vcc (3.3V) and GND. This may be used to interface additional sensors. 1.3. Microchip MRF24J40 2.4GHz The MRF24J40 wireless transceiver [5] provides the physical layer for your wireless communication network. This is a 2.4GHz (IEEE 802.15.4 compliant) device which transmits data rates up to 250kbps and is connected to the PIC via SPI bus, as well as a small number of digital I/O pins. The picture of Wireless transceiver is as follow. 1.4. MPLAB-ICD MPLAB-ICD is an inexpensive development tool for MICROCHIPs PIC16F87X series MCU. MPLAB-ICD is an online debugger, and a programmer. It works in the MPLAB-IDE integrated development environment, and use online serial programming technology of MICROCHIP (In-Circuit Serial Programming), the monitoring program is embedded to achieve real-time simulation in the simulation of the MCU (PIC16F87X). The simulation head is directly connected to the MCU socket of the application system, running the users application as a PIC16F87X. The picture of MPLAB-ICD is as follow. 1.5. Wireless sensor network Wireless Networks use radio waves, infrared, or any other wireless media to link to any devices. It can cover a large area, in which case it will be called a Wireless WAN, or it can cover an area or some floor of building, such as school, hospital and railway station, in that case Wireless LAN (WLAN) appear and describe the situation[4]. It appears a large number of wireless communication standards nowadays, including ZigBee, Wi-Fi, WiMax, GSM (Global System for Mobile Communications) et al. Wireless sensor network (background) became a more and more popular way to solve the problems of large-scale tracking and monitoring applications because it has low-data-rate, low-energy-consumption, and short-range link network [1]. It give people a chance to monitor and control the physical world in a more simple way. WSN applications include many ways in our life, such as industrial monitoring, security, electronics industry, military sensing, asset tracking and home automation. WSNs research has mainly pay attention to energy consumption, routing and data transmission, particularly focusing on collecting and data summary in specific networks with an associated sink node, called a WSN gateway [1]. Some research has carried out the interface of different sensor networks for a single or complex applications. Wireless sensor networks is aimed to monitor and control the physical data of environmental conditions at remove locations and it can collect their data to a main location and send their control command to achieve the result of remote control. A WSN includes plenty nodes, ranging from a few to hundreds and thousands, in addition each node may be linked to one or more other nodes. One node can be designed for carrying out one or more different sensors which have various functions and we can also design combined sensors choice to complete complex use or exchange data with another network[4]. A node for sensing is called a sensor node, everyone can collect the data of other sensor node. As a result, any place with a sensor node can get all the data with a very fast speed at any time. 1.6. Error detection Cyclic Redundancy Check Error detection segment is necessary in a data transmitting system since the correctness and efficiency of data transmitting must be ensured. In this project, there are 3 approaches which can be applied to error detection: parity bit, check sum and cyclic redundancy check (CRC). Parity bit is also known as check bit, the function of which is to judge whether a number of 1-bits in the string is even or odd by adding a bit to a string of binary code. The realisation is that the bits with value 1 is counted for even parity while the coding reverses for odd parity. Although parity bit is easy to implement, the shortcoming is apparent that only when there are 1, 3, 5, à ¢Ã¢â€š ¬Ã‚ ¦ bit(s) errors can the error be detected. The principle for check sum is to define a string with a small size with designed algorithm of calculating, and the result of the calculations of before and after the transmitting will be different even the data changes slightly so the error could be detected in this way. Similar to parity bits, the disadvantage of check sum is that error cant be detected under some circumstances. Cyclic redundancy check (CRC) is a method of error detection that is easyto be implemented by shift register and look-up table in S/W. The process is shown in figure1. In this project the value of P(z) is 0x91 (11001 in reversed binary) which is known as generator polynomial and the divider. Assuming that the data needed to be transmitted is 110011000, then we have the message polynomial D(z). C(z) is the remainder which is calculated by D(z) divided by P(z). The realization of division operation is by XOR. Only when the least significant bit of 1 byte of the message is 1 will it XOR with CRC polynomial, then we should shift it to the next bit and repeat the XOR. At the transmitter, the string of CRC depends on the whole frame on a bit-by-bit basis with binary division. And at the receiver, the received bit string is again divided by the same bit-by-bit basis with a serial shift register. The resultant CRC result should be all zeros at the end of the frame, or there must be errors in the process of data transmitting.

System Design 2.1. Sensor design and calibration and Analogic digital converter ADC In our group 4 kinds of sensor are designed to meet the requirement, and they are temperature sensor, light sensor, touch sensor and sound sensor. In order to obtain data from all the 4 sensors in the wireless network, a PCB board is required to connect to the sensor node board. In the lab, a breadboard is available for testing the circuit. When finishing the circuit on the breadboard, it can be interfaced to PC to have a preliminary test. If done, a PCB board will be used to finish the final product which can connect to node board. The method of calibration is to get the value of light, sound, temperature or touch that is detected using physical measurement. For example, if the temperature of the environment T0 and the result of the ADC conversion D0 that collected by the sensor in the same testing environment are known, we can derive the proportional function of temperature and ADC data with another pair of coordinate (T1, D1), which is obtained by changing the temperature of testing. Then the code that controlling display of temperature value should be modified so that by the time the temperature of the environment changes, the displaying value on the PC is exactly the temperature. Code for this part is shown as following: 2.1.1. Temperature sensor Negative Temperature Coefficient (NTC) thermistors are temperature sensitive semiconductor resistors which decrease in resistance value when absolute temperature increasing. Change in the resistance of NTC thermistor can be brought about either by a change in the ambient temperature or internally by self-heating resulting from current flowing through the device. (NTC Thermistor Discs and Chips | Ametherm, Ametherm, 2017. [Online]. Available: http://www.ametherm.com/thermistor/disc-and-chip-ntc-thermistors. [Accessed: 07- Jan- 2017].) Most of the practical applications of NTC thermistors are based on these material characteristics. Time and temperature are two of the most frequently measured variables. There are various ways to measure temperature electronically, most normal is by thermocouples and negative temperature coefficient (NTC) thermistors. In addition, NTC temperature sensors can operate over a wide temperature range (-55 to +300 °C). They are stable throughout a long time, and are small and cheaper than other kind. [3] Figure 1 circuit of Temperature Sensor It can be seen in the figure 1 that temperature Sensor is a more complex circuit design. On the left part It=Vcc/(R1+Rt) and Vt=Vcc*Rt/(Rt+R1), then connect the line to the positive side of the LM358 amplifier to amplify circuit and Vt becomes the input of the amplifier. After that, use formula V0 = Vt*(1+R3/R2) to get the voltage value of v0. From this formula we can know, the value of V0 depends on R3 and R2, so R3 and R2 are both simply chosen 10 Ohm. Then the voltage value of V0 is exactly twice as much as that of Vt. Next use formula to transfer ADC data to temperature, when it comes to the lab temperature (23 degrees Celsius), ADC data is 613. While it comes to the people body temperature (abort 38 degrees Celsius), ADC data become 530. Finally, we can calculate the linear parameters by these two sets of data. 2.1.2. Light sensor The Light Sensor is a passive devices that transfer light energy visible or invisible into a output of voltage signal. Thus Light sensors are more commonly known as Photoelectric Devices or Photo Sensors [2]. Photoelectric devices can be classified into two main categories, those which generate electricity when illuminated, such as Photo-voltaics or Photo-emissives etc, and those can change their electrical data (voltage) in some way such as Photo-resistors or Photo-conductors. [2] Light sensor is the easiest sensor of our 4 sensor, so we also use the simplest structure, when luminance become strong, the value of photosensitive resistance become larger. Thus the voltage of Vt increase which result in the raise ADC data. Then use formula to transfer ADC data to luminance, when it is dark (lux 0), ADC data is 30. While it comes to the lab light (about 330 lux), ADC data become 895. Finally, We can calculate the linear parameters by these two sets of data 2.1.3. Sound sensor 2.1.4. Touch sensor The MPR121 is the second-generation sensor controller after the initial release of the MPR03x series devices. The MPR121 will feature increased internal intelligence in addition to Freescales second generation capacitance detection engine. Some of the major additions include an increased electrode count, a hardware configurable I 2Caddress, an expanded filtering system with debounce, and completely independent electrodes with auto-configuration built in. The device also features a 13th simulated electrode that represents the simultaneous charging of all the electrodes connected together to allow for increased proximity detection in a touch panel or touch screen array [5]. 2.3. Time Division Multiple Access TDMA It is required that there are at least 4 nodes of sensor without collision in a wireless transmitting network based on a certain channel. Each sensor must be ensured to be able to receive and transmit, in other words, each node can serve as both a receiver and a transmitter. The node which connects to the PC is responsible for the display of the data that collected by each sensor and each sensor is supposed to send the data string to the chosen node within 1 second. There will be collision with the four nodes if we dont define the order of the data transmitting and receiving or just simply define by applying time delay, hence TDMA is necessary to meet requirements above. TDMA is a method of communication technique that derived from the P2S (parallel to serial) conversion. In the process of TDMA of this project, receivers obtain a same signal at the same time but only the appointed receiver reacts and does the next action, which is then transmitting and serving as new transmitter, and the new transmitter will wait for the next appointment without doing nothing unless it is appointed once again, which means it gets the same order in a new loop. The process repeats and there will not be data collision in the transmitting and receiving. As is illustrated in figure2, there are 4 nodes so 4 slots are needed in 1 second according to the requirement, hence each slot takes up 0.25 second, during which time of period each node should finish data transmitting, so the calculation of the time that is needed for sending and receiving is necessary. 2.3.1. Data packet structure 2.3.2. Timers We apply timer0 to control the time of running, different initial values have been given to timer0 in each slot so that transmitting and receiving within 1 second without collision can be ensured. In this case, node 4 is the main node which connects to the PC. The start of the process is the transmitting of node 4, and by the time other 3 nodes receive data from node 4, the text packet ID of the transmitter will be checked and only node 3, which is the transmitted ID 4 minus 1, will display the data that collected by node 4 and transmit its own data collected by its sensor. Following actions will be carried out by node 2, and node 1 within a certain time of period, like shown in figure3. Figure3 4. IoT Data Service and Visualisation

PG Promotions Strategy Analysis

PG Promotions Strategy Analysis PG has changed its promotions strategy for Tide Introduction Procter and Gambles Tide is the most well-liked and popular detergents across the world. This product serves as a pride for PG in announcing it as a flagship brand. Company undertakes promotional strategy basically to boost the sales of the products and stimulating customers to buy the products. Tide uses different strategies in promotion which Includes online marketing, magazines and television. Reasons for the shift in promotion strategy of tide In todays changing business world, the consumers have become more dynamic and varied in their preferences as well as they are getting more knowledgeable and demanding. Therefore, the company is focusing on its customers and client in order to get huge success. These transitions have forced the PG to make the changes in the promotional strategy in order to become more customers centric (Kotler, 2002). Secondly, PG observes that in order to maintain leading position in the field of laundry it has to make a shift in the promotional strategy by employing new techniques of promotion. Findings have exposed only 8% shopping is carried out by men where as female account for 56%. The adoption of changed promotional strategy by PG has proved to be beneficial in attracting the consumers and making them loyal for the brand. Apart from this, it has helped the company in gaining competitive advantage (Penner, 2006). Changes adopted by PG in promotional strategy for tide PG underwent series of changes in promotional strategy for Tide. The promotional strategy comprises host of the activities such as advertising campaign, running public relation activities, offering of free gifts, distribution of free sample, offering temporary discounts. Earlier $5.5 billion was spent by Procter and Gamble in the year 1999 for advertising globally. Thus, making it worlds major advertisers. Procter and Gamble reaps the benefits from electronic and print media internationally. PG new promotional strategy focused on the creating an emotional appeal rather than just marketing a product. It linked the product best with the emotions of the people. As a result it changed its tag line for Tide as Tide knows fabric best. The company believed in promoting the product in such a manner that it makes an impact in the minds of customer and speaks to them in an effective manner. Therefore, the PG is putting all its efforts towards increasing the consumer feel- good for its products (Berner, 2006, May 01). As a recent change, the company is using latest technique of Information Technology as a promotion strategy for Tide. The use of these technology helps to explore the new opportunities. For Tide PG is using online marketing systems, magazines and television. For promoting the sales, PG is using the Q Interactive, which is an online marketing service. Through this technique, it interacts with the target market. The Q network promotes the clients to obtain free Tide products signing up to a Tide ad. Simultaneously they can have an access over Tides e-mail newsletter. Once the newsletter is sign up by customers, the customers gets the updates of the latest promotions or products. This technique is successful for the company as it fulfills the various goals of promotion (Promotional strategy, 2003). Apart from this, PG strategy focuses in searching women having huge social networks i.e. the women ranging from the age group of 28 to 45, who further chats with about 25 to 30 other women. On the other hand a normal mom chats to approx five. Several such connectors are present on the internet along with the banner like iVilllage.com. Vocal point moms serves as a recent new strategy adopted by the company, these are the mailed packets depicting the detergent and a cheery girl (Berner, 2006, May 29). Apart from this, to advertise Tide in TV and radio PG promotional strategy is focusing on the effective opening punch line, on the products of competitors, authentication by experts or well-known authorities and finding the weak point of competitor. In order to promote the Tide on site, the promotion strategy focuses on the content of site i.e. depth, breadth, way of presentation and time duration. Apart from this, emphasis is given on the updating the site and space for comments, suggestion and feedback. Competitive advantage Promotional strategy plays a vital role in gaining competitive advantage or edge over the competitors. The new promotional strategy adopted by the PG like online marketing and Vocal point moms will help the company in gaining the market share and getting wider access to the customer. The company will gain the competitive advantage as these strategies will help in retaining the loyal customer and getting the new ones. As a result, this will pose a threat to the competitors and make the Tide more acceptable among the customers (Ramaswamy, Namakumari, 2007). This strategy will help the company in maintaining its position as leader in the market. Through the online advertising it has personalized its services by providing the latest updates of the products and easy accessibility for the products ultimately it will help in building brand image and creating value to the customers. Thus, it will gain competitive advantage by implementing effective promotional strategies. References Berner, R. (2006, May 29) I Sold It through the Grapevine. Business Week.

Coduction Convection Radiation :: essays research papers

Conduction, Convection, and Radiation   Ã‚  Ã‚  Ã‚  Ã‚  Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers, Conduction, Convection, and Radiation. The first kind of heat transfer, conduction, is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly, therefore making the pan hot. The next type of heat transfer is convection. Convection is heat transferred by a gas or liquid. Such as dumping hot water into a cold glass of water, making the water overall warmer. The last type of heat transfer is radiation. Radiation is when the heat energy travels in actual waves. The suns energy gets to earth because of radiation.   Ã‚  Ã‚  Ã‚  Ã‚  These three types of heat transfer can be easily found in the activities we have been doing the past couple of weeks having to do with a universal dwelling. They can mostly be seen when we are trying to test the heating and cooling capabilities of our universal home model. Conduction can be seen when the ice touched the cans full of insulation. The cooled cans touched the installation inside the can making it cooler. Convection can be found al over the place in our experiments. When we heated our model dwelling with the heat lamp the outside of the house heated. This in turn heated the air inside making the air temperature rise. Also, when we put the insulation cans in warn water the water heated up the can. And lastly, in the insulated can experiments, both cooling and heating, when the cans temperature was changed it in turn changed the air temperature

Poverty in Nigeria Essay -- Poverty Essays

Poverty in Nigeria Nigeria is one of the leading oil producing countries in the world. It makes billions of dollars annually, yet the majority of the population lives in poverty. With around 70% of its people living with this problem it is also one of the poorest countries in the world ( Nigeria 's economy dominated by oil ). One of the major contributors to this problem is government. Because the country is well known for its lack of leadership the money made through oil trade is kept by rich benefactors, and the poor are left with nothing. Another major problem that is increasing poverty is Nigeria's population. The amount of people being born is far exceeding the amount of jobs available for them. Due to these two factors the level of poor people living in Nigeria today is staggering. The gap between the rich and the poor is so large that there is almost no inclination of a middle class at all ( Thomas ). If Nigeria wants to get rid of this gap then both the government and the increase in population growth will have to be dealt with. Government is one of the major issues in Nigeria today. Continually corrupted and constantly unstable it accounts for the majority of the problems relating to poverty in the country. With major amounts of money coming in from oil export it would seem logical that the population would see some of the profits, but they don't. Rich benefactors who lead the country take the profits and gain income for themselves. In return they leave costs for improving community life up to the people to deal with. Because of this aid to the public is limited. Health care is non existent, village improvements are unheard of, and the cost for food and other essential materials are increasing. These issues then ... ...r issue that needs to be changed is the population growth in the country. Because of the lack of available jobs, and the amount of people who need work, there are beginning to be conflicts and deaths as a result. Nigeria is a country with mass potential, but nothing is being done to take advantage of it. The country needs many things to establish this gain, but the first step would be a major change in the way the country is ran. If it doesn't change this then the potential that it does have will vanish and the ability to maintain the country will be gone. Citations: Nigeria 's economy dominated by oil . 16 Jan. 2002 .

Digital Fortress Chapter 42

Inside Node 3, Susan caught herself pacing frantically. She wished she'd exposed Hale when she'd had the chance. Hale sat at his terminal. â€Å"Stress is a killer, Sue. Something you want to get off your chest?† Susan forced herself to sit. She had thought Strathmore would be off the phone by now and return to speak to her, but he was nowhere to be seen. Susan tried to keep calm. She gazed at her computer screen. The tracer was still running-for the second time. It was immaterial now. Susan knew whose address it would return: [email protected] Susan gazed up toward Strathmore's workstation and knew she couldn't wait any longer. It was time to interrupt the commander's phone call. She stood and headed for the door. Hale seemed suddenly uneasy, apparently noticing Susan's odd behavior. He strode quickly across the room and beat her to the door. He folded his arms and blocked her exit. â€Å"Tell me what's going on,† he demanded. â€Å"There's something going on here today. What is it?† â€Å"Let me out,† Susan said as evenly as possible, feeling a sudden twinge of danger. â€Å"Come on,† Hale pressed. â€Å"Strathmore practically fired Chartrukian for doing his job. What's going on inside TRANSLTR? We don't have any diagnostics that run eighteen hours. That's bullshit, and you know it. Tell me what's going on.† Susan's eyes narrowed. You know damn well what's going on! â€Å"Back off, Greg,† she demanded. â€Å"I need to use the bathroom.† Hale smirked. He waited a long moment and then stepped aside. â€Å"Sorry Sue. Just flirting.† Susan pushed by him and left Node 3. As she passed the glass wall, she sensed Hale's eyes boring into her from the other side. Reluctantly, she circled toward the bathrooms. She would have to make a detour before visiting the Commander. Greg Hale could suspect nothing.

Developing Virgin Coconut Oil-Based Products

One of the definitions of â€Å"virgin† in the Merriam-Webster pocket dictionary is: â€Å"fresh, unspoiled; especially: not altered by human activity.† Virgin coconut oil (VCO or VCNO) is produced from fresh coconut meat (non-copra). This does not pass through RBD processes. It is produced without the use of chemical and heat and does not contain aflatoxin/PAH’s. It retains its vitamin content, especially Vitamin E, an antioxidant, after undergoing the natural process of producing the virgin coconut oil. It is rich in lauric acid, an acid naturally found in mother’s milk that helps develop and strengthen the immune system of newborn babies.It contains medium chain fatty acids that is easily digested by the body and converted to energy.   The virgin coconut oil is a truly unrefined coconut oil made from organic coconuts. Testing done in independent laboratories reveals a 50% – 53% content of lauric acid. No chemical or high-heat treatment is used, and this oil contains no trans fatty acids. The virgin coconut oil has been extracted in an old-fashioned traditional method that has been used for hundreds of years. The coconut trees where the coconuts are sourced by producers are certified organic according to strict USDA standards.This high-grade virgin coconut oil has a long shelf life due to coconut oil's natural anti-oxidant properties. It has the longest shelf life of any plant oil (Tropical Traditions Virgin Coconut Oil, 2005). This product is popular in tropical countries. However, marketing of Virgin Coconut Oil is still not well-established in the United States and Europe.Marketing DescriptionVCO can provide instant energy to the body. According to experts the medium chain (C8 – C12)   fats in VCO is similar to the fats in mother’s milk, that gives babies immunity from diseases. The medium chain fatty acids have antiviral, antimicrobial, antifungal and antiprotozoal properties. It was found out that the most potent is the lauric acid (C12) and its monoglyceride form monolaurin being mentioned as the most potent against lipid coated microorganisms which are not normally cured by ordinary antibiotics.Among the vegetable oils traded in the world, coconut oil is the richest source of medium-chain fatty acids (64%) and lauric acid (48-53%). The numerous health benefits of coconut oil are finally again reaching the mainstream. These benefits are reducing risk of heart disease, promoting weight loss when and if needed, supporting immune system health, reducing your risk of cancer and degenerative diseases, supporting a healthy metabolism, providing an immediate energy source, helping to keep skin healthy and prevent age-related damage, supporting the proper functioning of the thyroid gland, and preventing infections due to harmful bacteria, viruses, yeasts and other micro-organisms.These unique health benefits of coconut oil are directly related to its chemical structure, or more precisel y, the length of its fatty acid chains. That is, coconut oil is comprised of medium-chain fatty acids (MCFAs), also called medium-chain triglycerides or MCTs. Coconut oil is nature's richest source of these healthy MCFAs. By contrast, most common vegetable or seed oils are comprised of long chain fatty acids (LCFAs), also known as long-chain triglycerides or LCTs.Objectives and IssuesPromoting VCO will be aimed at the three benefits of the product:Health BenefitsThere are several reasons to explain why long-chain fatty acids are not as healthy as the MCFAs in coconut oil. For one, LCFAs are difficult for the body to break down. They must be packaged with lipoproteins or carrier proteins and require special enzymes for digestion. Also, LCFAs put more strain on the pancreas, the liver and the entire digestive system. These LCFAs are predominantly stored in the body as fat. (That's why most people buy into the myth that fats are automatically â€Å"fattening†). LCFAs can be depo sited within arteries in lipid forms such as cholesterol. On the other hand, however, the MCFAs in coconut oil are healthier, because MCFAs are smaller.They permeate cell membranes easily, and do not require lipoproteins or special enzymes to be utilized effectively by your body. MCFAs are easily digested, thus putting less strain the digestive system. This is especially important for those of with digestive or metabolic problems. MCFAs are sent directly to your liver, where they are immediately converted into energy rather than being stored as fat. MCFAs in coconut oil can actually stimulate your body's metabolism, leading to weight loss (Mercola, 2006).Social BenefitsA noteworthy social benefit of the virgin coconut oil is in positive impact of the virgin coconut oil in obesity. When virgin coconut oil is used by people suffering from obesity, immediate response of the body can be observed. The metabolism of the person who took in virgin coconut oil in their system is chronically inhibited by something that was easily alleviated by â€Å"dilution† or molecular competition.Putting a tablespoonful of coconut oil on some rice during meals and half an hour later will result to normal breathing. The skin become pink and pulse may become normal. Over the next few months, the weight will be slowly and consistently decreasing. Eating more coconut oil lowered weight for some pounds. The anti-obesity effect of coconut oil is clear in the animal studies (Peat, 2004).Environmental BenefitsThere are a number of environmental benefits of virgin coconut oil. Farmers who attempted to use virgin coconut oil for fattening their animals found out that the virgin coconut oil made the animals healthy and active. The waste products excreted by these animals are not hazardous to the environment due to its organic and safe to the environment nature (Peat, 2004).An important thing to note in the production of the virgin coconut oil is that none of the products from this proce ss are wasted. The ground outer shells of the coconut are used for matting and packing fresh plants and flowers. The empty coconut shells are burned for fuel to supply heat for drying the meat. Other uses of the empty coconut shell is in cooking or heating for fuel for a variety of purpose. The exhausted meat as the waste product in the production of virgin coconut oil is often fed to livestock as a nutrient rich meal (Jamaican Gold: Raw Handpressed Coconut Oil, 2006).Product ReviewA.  Ã‚  Ã‚   Different Ways of Branding the ProductAlmost no product is perfect forever. And when the patent runs out, there is always someone who can make it cheaper. But even before the patent ends, there will likely be those who attempt an end run on your process. Most successful ingredient brands have continually refined their products to make them easier to use in manufacturing, or make them cheaper, or to perform better. This way, you will discover any opportunity to improve your product before so meone else does. Ingredient Branding is a different approach to building brand equity. This concept is a way to successfully introduce and market a radically new product.The usual way existing markets name the coconut oil is Virgin Coconut Oil. But this product being proposed here will have the name Coconut Virgin Oil or CVO for short. The CVO will be applied for trade marking that makes the logo come out as CVOTM.Branding the product as such will eliminate the basic idea that the product is of coconut virgin oil. This type of branding is called logo type branding. Marlboro didn’t name themselves Cigarettes or Pepsi naming their company as SoftdrinksTM. CVOTM  Ã‚   as a corporate ID will carry different types and forms of virgin coconut oil products. Each of these forms will have their own sub branding. For example:Product for medicinal benefits will be branded CVOTM   Medicinal.Product for beauty benefits will be branded CVOTM   Beauty.Product for culinary benefits wil l be branded CVOTM   Kitchen.Once the brands are decided and set, personalities will be chosen to partner these brands. A coconut tree will not be used to promote the product. A coconut tree may be developed as a mascot but personalities that can claim the benefits of the product will be more effective. These personalities will be chosen according to their credentials that are palatable and appealing to the target markets.B. Threat of SubstitutesThreats of substitutes are virgin olive oil, virgin pine oil, red palm oil, grapeseed oil, flaxseed oil and many others. Virgin olive oil is obtained only from the olive, the fruit of the olive tree, using solely mechanical or other physical means in conditions, particularly thermal conditions, which do not alter the oil in any way. It has not undergone any treatment other than washing, decanting, centrifuging and filtering.It excludes oils obtained by the use of solvents or re-esterification methods, and those mixed with oils from other s ources. It can be qualified as a natural product, and virgin olive oil can have a designation of origin when it meets the specific characteristics associated with a particular region. Virgin olive oils can have the following designations and classifications depending on their organoleptic (taste and aroma) and analytic characteristics. Tthe degree of acidity refers to the proportion of free fatty acids, not to the taste (Olive Oils Definition, 2006).Virgin pine nut oil (VPO) is the first and only natural and effective appetite suppressant currently known to man. When ingested – either in its pure form or as part of delicious foods – this tasty oil stimulates the abundant release of cholecystokinin (CCK). CCK is a substance naturally produced in the duodenum in the presence of fats and proteins. When delivered to the brain, it tells us to stop eating, thereby reducing the amount of food we consume, as well as our overall intake of calories (Organic Oils, Butters, and Nu t Butters, 2006).Red Palm Oil is produced from the fruit of the oil palm, Elaeis guineensis. It is a vegetable oil, not from an animal or dairy product and therefore does not contain any cholesterol (Organic Oils, Butters, and Nut Butters, 2006).Grapeseed Oils Infused with all-natural, fresh herbs, our Salute Sante! Infused Grapeseed Oils shine with delicious flavor and have a light texture and mouthfeel. A tasty substitute for butter, margarine and other saturated fats, use these oils as a delicious dip for bread, drizzle over salads and fresh vegetables, or use as a â€Å"liquid spice† in your favorite recipes (Organic Oils, Butters, and Nut Butters, 2006).Flaxseed oil contains linoleic acid, an essential fatty acid needed for survival (Thompson,   et al., 1996). According to the authors, unlike most oils, it also contains significant amounts of another essential fatty acid, alpha linolenic acid (ALA). They further mentioned that the effect of ALA as an isolated substance , and of flaxseed oil on the risk of cancer in humans remains unclear, with most animal and test tube studies suggesting protection, and some preliminary human trials suggesting cause for concern.They have stressed, however, that it is premature to suggest that ALA and flaxseed oil will either cause or protect against human cancer at this time (Thompson, et al., 1996). Flaxseed oil is not suitable for cooking and should be stored in an opaque, airtight container in the refrigerator or freezer. If the oil has a noticeable odor it is probably rancid and should be discarded (Flaxseed and Flaxseed Oil. Health Notes, 2006).C.  Ã‚  Ã‚  Ã‚   Competitive RivalryDespite the numerous organic oils that are available in the market, competitive rivalry is existing in the market. Since the introduction of the virgin coconut oil in the market, there is an observed potential and competitiveness of the virgin coconut oil in the international market (Virgin Coconut Oil, 2006).D.   Product Uniquen essCVO is a the brand that values and sells integration. The integration of all three benefits of the coconut virgin oil will spell originality of this product. Many sellers of virgin oil are in the market but all their existing brand marketing remains like the back yard type. CVO will be striking because it will project a global brand bringing all the benefits of CVO that can be accessed by different local and inter-nation markets, single consumers or bulk buyers that use the CVO in their businesses.The vision of CVO is to project a global brand that promotes the coconut and its organic benefits to human kind.Marketers should understand that when global brands are desirable, it is not simply because they are global, but rather because their globalness implies other traits, such as quality and prestige. ‘There's a certain cachet of quality that comes with being available around the world, but it's not automatic,' says third co-author, Dana L. Alden, a professor of marketing at the University of Hawaii. ‘The brands that tend to be successful around the world tend to be of higher quality and are promoted as such (The Global-Brand Advantage, Spring 2003).Action ProgramThe mission of the product is to earn from promoting a healthy lifestyle using the coconut virgin oil. The goals of the product is to sell through distributors and retail outlets the many forms of CVO packed in a variety of ways suited for different uses. Thus, CVO will be promoted as a product beneficial to the body, lifestyle and environment. Promotion will be focused on the internet, health stores and grocery stores. Three promotional strategies are explained below.The plan will use personalities to promote the product. Using this strategy is still a cut above the rest using personal testimonies from man on the streets. The product must find people from different fields to help promote it. A deemed scientist will be found to endorse its chemical stability and safety. A super star will promote its beautifying effects. A known woman – mother advocate will be helpful in promoting its cooking and lifestyle benefits.2. Another plan for promotion will include giving away trial samples for free. Each time they buy a certain amount of product, the clients will be awarded a free pack that they can share to their friends who would like to try. Advocates who believe in the product can easily promote it. Giving them resources to help their own little promotion will have good future effects.3. A good promotional activity is advertisement in the various media such as newspapers, television, radio, and other events. The advertising arm must maximize events that center on alternative lifestyle and venues that promote environmental consciousness. Sponsorships in cash or in kind is also a good way to help promote the product. Users who can give the advertising arm information that can lead towards the promotion of the product in their communities will be awarded free produ cts.Proposed Budget$ 50,000 – Product Development and Importation of processed virgin coconut oil$ 30,000 – Advertising Costs$ 20,000 – Miscellaneous (Salaries, Incidentals)$100,000 – TotalProfits will be earned through proper management of sourcing of raw materials. Processed and bottled can be bought at an average of $ 3.00 per 500 ml. Prevailing retail price without shipping costs is $17.00 per 500 ml on the average. Retail is more than five times the cost which makes it viable for product development.ControlThree scenarios are seen as the CVO product penetrates a market. One, it is well accepted. Two, CVO is generally rejected. Three, CVO becomes unnoticed.The first scenario is favorable. Promotions and marketing goes into the market, information is heard, the product is sampled, and the consumers love it. This will look and sound easy but the challenge in this scenario is how to make these CVO goers and users become advocates. A bigger challenge is h ow to sustain the quality of the product they liked. There will be times when a consumer who easily accepts a new product has also the tendency to easily change his mind when another product comes along. These consumers will always try something new and thereby one can describe their product loyalty at a minimum. Making these consumers loyal is the job of the company.Works CitedJamaican Gold: Raw Handpressed Coconut Oil.   29 Nov. 2006.

Linguistic Reading Response Paper on “The Celtic Languages”

It is interesting to note that the term ‘Celt’ is a linguistic term first mentioned in the writings of Greek and Roman ethnographers and historians (MacAulay, p. 2). My idea of the concept is that of a particular people with a distinct language who once inhabited Great Britain. It turns out that this language, generally known as Continental Celtic, has a range of dialects once spread out across the various peoples of Europe such as in Gaul and northern Italy, yet died out on the European continent a few centuries back. Celtic survived however, in the British Isles and in Ireland, which is quite a feat given the dominance of Latin and later English settlements. In terms of linguistic affinities, Celtic is recognized as an Indo-European language though it is of interest to note that experts regard it as having archaic features (MacAulay, p. 3), i.e. its lack of a fully developed infinitive, differentiation of gender in numerals 3 and 4, among others, sometimes attributed to its being a ‘peripheral’ language removed from an innovating center. Variations between the Celtic languages, i.e. Continental and Insular, appear to be a convoluted matter best left to linguists. Ultimately the evolved form of the modern Celtic languages has special typological features which are both archaic (conservative) and innovative. Locative structures used to express location and possession are utilized to express aspectual modes, which in turn cover the range of progressive, prospective and perfective aspects in Scottish Gaelic, Welsh, and optionally in British (MacAulay, p. 6). On the other hand, Breton and Irish have innovated based on their majority contact languages French and English, to develop new perfective constructions, as contact with these languages is a primary accelerating source of innovation in Celtic tongues. Thus, languages continue to evolve as its speakers, in the course of their interaction with those of other cultures, are exposed to foreign influences in the on-going social interface between peoples and nations in an increasingly globalizing world. Linguistic Response Paper on the â€Å"Creole Continuum† The so-called ‘Creole continuum‘ evolve in situations in which a creole coexists with its lexical source language and there is social motivation for creole speakers to acquire the standard so that the speech of individuals takes on features of the latter – or avoids features of the former – to varying degrees (p. 50). Considering that linguists for a long time were unsure on how to classify varieties with both creole and non-creole features, particularly the English-based varieties of the West Indies, it appears significant to consider that among the many Negro slaves in different parts of America, the jargon upon becoming the only language of the subject group, is a creolized language considered inferior to the masters’ speech yet nonetheless subject to constant leveling-out and improvement in the direction of the latter (Bloomfield, 1933, p. 474). Linguists such as DeCamp attempted to work out a theoretical model that could deal with variation in a sufficiently rigorous manner, in reaction to the transformational generative grammar coming to dominate American linguistics. The general usefulness of the continuum model gained wide acceptance by the mid-1970s, yet it is true that it fails to explain why Atlantic creoles in particular share so many structural features not found in their different lexical source languages (p. 58). Thus the shift back into a universalist theory giving primacy to language acquisition. Chomsky (1965) had proposed that children were born with a predisposition to recognize certain universal properties of language that facilitated their acquisition of the language of their particular speech community (p. 58). Yet such an assertion is still open to scholarly debate and argumentation. It would thus appear that the answer to the creole question remains elusive, despite advances in linguistic studies and theory. References MacAulay, Donald. â€Å"The Celtic languages: an overview†

Heart Sounds Case Essay

1. Dr. Baker spends a long time listening to (auscultating) Caleb’s heart. a. Where on the thoracic surface do you auscultate to the tricuspid, mitral (bicuspid), pulmonary, and aortic valves? Auscultation for the tricuspid valve would be in the left sternal margin of the 5th intercostal space. The mitral valve sounds are heard over the apex of the heart (5th intercostal space) in line with the middle of the clavicle. Pulmonary valve sounds are auscultated at the 2nd intercostal space at the left sternal margin. The aortic valve is heard at the 2nd intercostal space of the right sternal margin. b. Where do you think would be the best place to auscultate Caleb’s abnormal heart sound? Explain your answer. The abnormal heart sounds would best be heard over the tricuspid area – the lower left sternal border. This is the area which overlies the defect. 2. Caleb has abnormal heart sounds that tipped the doctor off to a problem. a. Name the normal sounds of the heart and indicate what causes these sounds. The normal sounds of the heart are â€Å"lub-dup† are caused by the opening and closing of the heart valves. The first sound – lub- is from the closing of the mitral and tricuspid heart valves. The second sound -dup- is from the closure of the pulmonary and aortic valves. b. In relation to the normal heart sounds, when would you expect to hear the abnormal sound Dr. Baker heard? Explain your answer. A ventricular septal defect is a systolic murmur. The abnormal sounds can be heard during or after the first heart sound and ends before or during the second heart sound. 3. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. a. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? I would expect the blood to move from the left to the right ventricle. b. Based on your understanding of blood pressure and resistance in the heart and great vessels, explain your answer to question 3a. In the heart blood flows from areas of high pressure to areas of low pressure. Blood normally enters on the right side of the heart (deoxygenated), is pumped to the lungs and returns to the left side of the heart (oxygenated) which will then be pumped out to the rest of the body. In Caleb’s case blood will enter the right side of the heart, be pumped to the lungs and return to the left side  of the heart. Every time his heart beats, some blood is then forced through the VSD back to the right side. It then goes back to the lungs even though it is already oxygenated, so blood that is not oxygenated can’t get oxygen. A lower blood volume then remains in the left ventricle to be pumped out to the rest of the body. High pressure would occur in the lungs due to extra blood being pumped into lung arteries this make heart and lungs work harder. 4. When an echocardiogram is performed, the technician color-codes oxygenated blood (red) and deoxygenated blood (blue) a. In a healthy baby, what color would the blood be within the right and left ventricles, respectively? The right ventricle normally pumps blue blood because the blood is without oxygen and the left ventricle pumps red blood because the blood has oxygen. b. In Caleb’s heart, what color would the blood be within the right and left ventricles, respectively? It is both blue and red in the right ventricle because the already oxygenated blood flows back into the right ventricle and blood in the left ventricle would be red. 5. Caleb’s heart allows oxygenated and deoxygenated blood to mix. Based on your knowledge of the heart and the great vessels, describe other anatomical abnormalities that cause the mixing of oxygenated and deoxygenated blood. Atrioventricular Canal Defect is an abnormality that causes the mixing of blood. There is a hole in center of heart where the wall between the upper and lower chambers meet. The tricuspid and mitral valves aren’t formed properly and one large valve crosses the defect. The defect lets oxygen rich blood pass to the heart’s right side and mix with deoxygenated blood, then go back to the lungs. Another abnormality is Atrial Septal Defect (ASD), where the walls of the upper chambers of the heart don’t close completely, causing a left to right movement of blood due to the higher pressure. The mixing of oxygenated and deoxygenated blood may cause the right atrium and ventricle to enlarge due to the higher volume of blood. 6. What happens to Caleb’s systemic cardiac output as a result of his ventricular septal defect (VSD)? Explain your answer. Caleb’s systemic cardiac output will be decreased. His blood will enter the right ventricle be pumped to the lungs, return to the left ventricle and then be shunted  back to the right ventricle. This causes more blood to enter the right ventricle. The extra blood then leaving the right ventricle causes a volume overload to the lungs. Because blood is being shunted back to the right ventricle, there is a lesser volume of oxygenated blood that leaves the heart to supply the rest of the body. 7. One of the problems that worried Tiffaney was that Caleb seemed to be breathing too hard all the time. Let’s consider how this symptom is related to his heart defect. a. Describe what would happen to the blood volume and pressure entering the pulmonary circuit as a result of his VSD. In VSD the right and left ventricles are working harder, pumping a greater volume of blood than they normally would. Extra blood will pass through the pulmonary artery into the lungs causing, blood pressure to be higher than normal in the blood vessels and lungs. b. Describe what would happen to the myocardium of Caleb’s right ventricle as a result of his VSD. The right ventricular heart muscle will thicken and lose elasticity over time, causing the heart to work harder to effectively pump blood the lungs and rest of the body. 8. Based on the location of Caleb’s defect, what part of the conduction system might be at risk for abnormalities? It is extremely rare that VSD would cause a conduction system defect due to the fact that the two systems are different, different embryological development, yet are in close proximity to each other. It is possible for the bundle of His to be displaced, but usually is unaffected. Sometimes a branch of the bundle of His could be on a rim of the VSD, but is still able to function. The only tricky part is if surgery is needed, the doctor needs to be careful when closing the defect.
