Theme Of Memento - 842 Words

Christopher Nolan’s neo noir thriller film, Memento (2000), follows the life of the protagonist, Leonard Shelby, as he searches for the person who murdered his wife, whilst dealing with anterograde amnesia, forcing him to use â€Å"memento’s† to retain new memories. Through the employment of mise-en-scà ¨ne and sound design, the central theme of ‘the pursuit of vengeance’ could be conveyed. Additionally, the theme ‘the fragility of memory’, is illustrated to the viewer through cinematography and editing. These techniques and themes are most evident in the dramatic final sequence in the film, specifically when Leonard finally gets revenge and Teddy unveils the truth about John G to him. Through Nolan’s utilisation of props and costumes, Memento†¦show more content†¦This exemplifies that he no longer trusts his own memory and has begun to accept the horrifying truth presented to him by Teddy. Nolan’s application of close-up shots illuminates Leonard’s facial expression as he recognises the unreliability of his own memory when Teddy confronts him with the truth about his wife. Through Nolan’s application of editing, such as flashbacks, in Memento, the story of Sammy Jankis can be linked back to Leonard’s past as well as the central theme of the fragility and unreliability of memory. Leonard’s unreliable memory is clearly conveyed as the sequence rhythmically displays scenes showing that the protagonist’s wife survived the assault, which is evident as she removes the shower curtain from her head in a flashback. This indicates the unreliability of Leonard’s memory and the devastating result of ‘Conditioning [himself] to remember, learning through repetition’. Nolan’s employment of flashbacks within the sequence expresses Leonards desperate attempt to escape guilt through the fragility of his memory. This is exemplified in the flashback when Leonard’s memory of pinching his wife adjusts to him injecting insulin into her. Nolan’s utilisation of editing illustrates the fragility and unreliabi lity of Leonard’s memory, specifically when he learns that heShow MoreRelatedChristopher Nol An American Film Director, Screenwriter, And Producer And Auteur.847 Words   |  4 Pagesinternational film festival.Common themes and actors can be seen throughout Christopher Nolan’s films,he is also famous at narrating the movie in a non linear way.In the next paragraph im going to discuss why would i consider him as one of the best modern times auteur.

The Reagan Doctrine introduced the formulation of the doctrine in response to some detailed events, which encompassed the insubordination of the rebels in nations like Afghanistan and Nicaragua against the Soviet regimes (Carpenter, 1986). Reagan’s foreign policy intention was to eliminate the efforts of the Soviet Union to prolong its domination and from this time, he opted for the formulation of his doctrine to aid the rebels who in various countries of the world who were attempting to overthrown the Soviet regimes (Carpenter, 1986).

Physically, he had childlike energy levels. During sickness, Mozart continued to compose, give performances, travel, teach, and maintain a lively social life.

Shortly after Mozart death, gossip spread that in great jealousy, he murdered Mozart.Even though there was no real reason for Antonio Saltier to kill Mozart, people soon invented one. For example, the famous Russian writer, Alasdair Pushpin wrote a one-act play entitled Mozart and Saltier. In this play, Pushpin suggested that Saltier was overwrought with Jealousy because he knew that he could never write as beautiful music as Mozart. The real question is did Saltier actually kill Mozart? There is no hard evidence at all and the only points against Saltier are made up of rumor. And even Saltier said that its only rumor.After studying all the evidence supporting the disease theory, I have concluded that Wolfgang Amadeus Mozart probably died from a serious Illness, more specifically rheumatic fever.

The Olympic spirit Essay Example

The Olympic spirit Essay I believe this is both a true comment and a false comment. The fact that people are brought together through sport especially like the Olympics is true. The event does bring a mass of viewers around the world through TV and other commercial use and every 4 years there always seems to be a new face in the form of a country competing with the top countries in the so called biggest sporting event in the world. With this Baron Pierre de Coubertins ideal worked then or did it? When the modern Olympics were finally realised in 1986 on the 5th of April. Baron Pierre De Coubertin has made a remarkable achievement he managed to bring 13 nations together to compete against each other in nine different sports from four of the worlds continents at a time when travel and communications were often difficult. Coubertins ideal was that athletes should be free to compete in the Olympics no matter what there creed, colour or race. This is what Coubertin wanted and achieved, he had managed to bring people together on a world stage through sport. As the Olympics began to grow bigger and stronger and more countries began to become involved and in my opinion this is where coubertins ideal becomes to evolve in a negative way. As the Olympics became more popular and more people watched, the stakes rose. It soon changed from competing to need for winning and I believe this is where the question is false. Coubertins Olympics was about the sport and bringing people together, but soon politics began to rear its head in the event, something I believe should be left out of sport all together.

Also dubbed Hitlers games. This brought the most political controversy the Olympics had seen, something coubertin definitely didnt want to see. Hitler used the games as a display to show the world the strength of Nazi Germany. This was defiantely what the Olympics werent made for, taking away the whole ideal what Coubertin wanted. The games also caused segregation, Jews were excluded from selection from the German team this definitely not bringing people together. Racism was also brought about through these Olympics through the black athlete Jesse Owens who in the end became nothing short of an Olympic legend as he upset Hitler and the whole of Germany by beating the Blonde Lutz Long, this infuriating Hitler. With all these happenings, it threw coubertins ideal of bringing people together and done the complete opposite of moving people away from each other. I believe a big difference from coubertins modern Olympics and now is the change of the athletes from sportsmanship to gamesmanship. The athletes that competed in coubertins Olympics competed within the framework of the rules but most importantly intently for the spirit of the rules and in this case the Olympics. Now I see gamesmanship is now in order where the intention to compete to the limit allowed by the rules and beyond and if possible without penalty in order to win. I see this has become about due to what as I see as the main reason things have changed in Olympics and that is the rising of commercial activity in the Olympics. With the commercial side now about in Olympics the ideal has changed athletes goals have changed it now is for the money and the fame where as before this was never the case. Sponsors now have a huge place in the Olympics mostly every athlete is sporting a logo or name of some well known brand on there shorts or running suit all in the name of making money for themselves and the companies. This of course opens a wider audience with more people involved but in turn I believe this commerciality doesnt have a place in sport. Sport should belong with sport, where commercial should belong in commercial places like billboards and the papers. Coubertins ideal of bringing people together has happened but in an all negative way. The Olympic spirit seems to be put to the side, where money comes in nowadays. Drug use, cheating, poitical interference the Olympics has seen the lot.the two cs has taken over The biggest sporting even in the world controversy and commercial. People have been brought together but all in the wrong manner from what Coubertin wanted and how it used to be. In my opinion if the Olympics carry on this way the fire of the Olympic spirit will soon die out.

Downfall of Russia essays

Downfall of Russia essays Tzar Nicholas II - downfall of Russia It was Tzar Nicholas 2 political naivete and extreme obstinance that led to the downfall of the Russia Certain aspects of Tsar Nicholas 2s behaviour definitely contributed to bringing about the fall of the Russian Empire, however most of these qualities were not weaknesses in character as such, they were qualities we would associate with poor leadership. When we say weakness in character we mean being easily influenced/controlled by others. Nicholas himself was a firm believer in autocracy; he was virtually unmovable in this belief. And this obstinant belief clearly illustrates he stuck to his beliefs, although in his early years as tsar his uncles had huge influence. That said, the fall of the Russian Empire was not all a result of Nicholas character and poor leadership qualities, we must also see that the huge socio-economic changes happening as well as the outbreak WW1 hugely influenced the coming about of and the timing of the revolution. These changes would be hard for any government to manage. Nicholas 2s firm and obstinant belief of his commitment to autocracy can be clearly seen in a letter of reply he sent to a liberal zemstvo head before his coronation. I shall maintain the principal of autocracy just as firmly and unflinchingly as it was preserved by my unforgettable dead father (Alexandra 3)(Nicholas belief in autocracy they would have been put to rest.

Political Party Ads - Who Pays for Them

Political Party Ads - Who Pays for Them Finding out who pays for political party ads in election season can be tricky. Candidates and committees who purchase political party ads on television and in print are required to disclose their identities. But often times those committees have vague names such as Americans for Prosperity or Americans for a Better Future. Understanding who contributes money to those committees so they can buy political ads is an important function of democracy because the ads play such a large role in elections. Are they conservative or liberal in political philosophy? Do they have a special interest or issue they are trying to influence? It is sometimes difficult to discern what a committees motives are just by watching or reading political ads. Who Pays for Political Party Ads Generally speaking, there are several types of groups that pay for political advertising. They are individual candidate election campaigns such as those for President Barack Obama or 2012 Republican presidential nominee Mitt Romney; political parties such as the Democratic National Committee and Republican National Committee; and political action committees or super PACs funded by industries and special interests. Some of the largest special interests in American politics are abortion and gun-control opponents, energy companies and senior citizens. In recent years, though, super PACs have emerged has powerhouses in the electoral process. So have 527 groups and other organizations who seek to exploit weak disclosure laws and spend so-called dark money. How to Tell Who Pays for Political Ads It is easy to tell when an individual political candidate or political party buys airtime for ads. They will disclose their identities, often at the end of the ad. Typically, the wording is This ad was paid for by the committee to re-elect Barack Obama or I am Mitt Romney and I approved this message. Political action committees and super PACs are required to do the same, but they are not required to provide a list of major contributors or identify their special interests on the air. Such information is available only through the committees own websites or through Federal Election Commission records. Those records, called campaign finance reports, include details about how much a political candidate or political party is spending on political ads. Disclosure Controversy Political action committees and super PACs are required by law to list their contributors in disclosures filed regularly in Washington, D.C. Such information can shed light on whether those super PACs are conservative or liberal in nature. But some super PACs exploit a loophole in reporting laws not addressed in the legal case that led to their creation, Citizens United v. the FEC. Super PACs are permitted to accept contributions from nonprofit groups classified as 501[c][4] or social welfare organizations under the Internal Revenue Service tax code. The problem is that under that tax code, 501[c][4] groups are not required to disclose their own contributors. That means they can make contributions to super PACs in the name of the social welfare entity without having to disclose where they themselves got the money. Attempts to close that loophole in Congress have failed. Greater Transparency The Federal Communications Commission requires television stations that get paid to broadcast political ads to keep a record of who bought airtime. Those records are required to be made available for inspection to the public at the stations. The contracts show the which candidates, political committees or special interests are buying political ads, the length and target audience, how much they paid, and when the ads aired. Beginning in August 2012, the FCC also required television stations to post online all contracts with candidates, super PACs and other committees buying airtime for political ads. Those contracts are available at https://stations.fcc.gov.

Parents, screaming in the audience, show that they have devoted their lives to their children. Many are overweight and demand utter perfection from their children.

Parents seem to want to fulfill their own fantasy that they did not fulfill as children. They want their children to be perfect beauty queens, perfect performers, and perfectly dr essed. They spend thousands of dollars on each designer dress. They hire coaches and makeup artists. When a child is interviewed, she never speaks of her education.

Multiple Linear Regression Assignment Example | Topics and Well Written Essays - 2000 words

Multiple Linear Regression - Assignment Example del is linear in the sense that every predictor variable is either a constant or the product of a parameter (ÃŽ ²Ã¢â‚¬â„¢s) and a predictor variable (x’s). The researchers further investigated whether the multiple linear regression models provided a better description of the relationship between the wave modes than would a linear regression model with only a linear predictor. In the model, y (the response) is the ISOw (westward moving intraseasonal modes) and x (the predictor variable) is the ISOe (eastward moving intraseasonal modes). ISOe is further broken down to into more variables by applying power functions of the predictor variable to create a polynomial. Higher power terms are included in the model in order to seek evidence of any improvements in how they increase the accuracy of how wave modes are displayed. This selection is arbitrary and purely based on the assumption that it may lead to the development of a better model for depicting the relationship between the independent and dependent variables. Each of the introduced independent variables is then evaluated for significance (at the 5% level of significance) in order to establish its relevance to the entire model. Each item with a coefficient whose p-value falls below the 0.05 (5%) threshold is considered as being statistically significant. Such variables are retained in the model. The test of significance was repeated several times using the bootstrapping technique. A^sub s, T^ = (X^sup T^^sub t^X^sub t^)^sup -1^X^sup T^^sub t^Y^sub s,t+T^ by solving for a specified lag for the regression coefficients. In this equation, â€Å"T† is the matrix transpose, â€Å"a† the coefficients, and s the grid points (more easily interpreted as the lags). The regression equation involving the nonlinear terms is then tested for suitability against the ordinary linear regression. The model that appears to explain more variance in the response is deemed better.

Rise of Two Operas Essay Example for Free

Rise of Two Operas Essay The Italians and the French have been two prominent figures in the world of opera music. Their music in the field of tragedy has been flourished by history and emerged from different social context and background. Opera traced its roots from Italy. Opera, in its earliest form can be traced from various types of Italian literature. The themes, moods, and subjects of opera can be associated with Italian poetry, drama, and allegory (Kimbell, 1991. p. 19-21). More importantly, opera particularly the opera seria, has originated at the height of the Renaissance period. The Renaissance art were centered on man. It revolved around man’s greatness, man as passionate, and as virtuous. The themes of opera described the life of the Italians as a whole, which is according to Luigi Barzini: The pleasure of Italy comes from living in a world made by man, for man and on man’s measurement (cited in p. 3). A theme deeply embedded in reality. Revolving around this theme, opera became for the sole purpose of entertainment. However as Renaissance became a period for the flow of rising ideologies, the face of opera changed into a moving art combined with philosophy and moral teaching. This aim served the purpose of educating its audience and not just by mere entertainment (Kimbell, 1991. p. 182). It was Apostolo Zeno and Silvio Stampiglia who created operas that were historical in nature. Stampiglia wrote a series of operas relating early Italian history and Zeno’s works have long been distinguished as a combination of moral and scholarship significance (p. 183). The Italian opera seria had not been completely tragic but became more serious. Metastasio offered ‘suspense’ or in Italian ‘sospensione’ in place of tragedy, in which the audience were presented the internal conflicts of the protagonist. Seeing this kind of progression, the French opera scene has its trend going on as well. However, as mentioned from the beginning, opera had its roots originating from Italy. There were no French composers at that time. It was an Italian national who moved to France, named Jean-Baptiste Lully who was said to have popularized opera to the French people (Edwards, 1862. . 14). Origins of French opera may have come from other form of arts such as ballet. Ballet has incorporated music with dramatic dance routines thus making as a basis into recreating a dance that has dramatic dialogues in the form of music (Grouts Williams, 2003. p. 22). Lully gained full monopoly when spreading his music due to his friendship with King Louis XIV. He collaborated with the likes of Quinault to create operas which they called tragedie en musique (Anderson, 2003. p. 3). It is important to note that though it was the time of Rennaisance in Italy, it had been a slow progress for France to grasp the music from other countries. Since Lully gained monopoly for production of operas, the monarchy controlled the flow of music from outside in accordance to Lully’s advice (p. 1). Basing it from here, the themes of the operas that were being played within King Louis XIV’s court still centered on mythical themes rather than on humanism. The plot of tragedy focused on mythical characters and fictional conflicts (Easterling, 1997. p. 136).

Black Sox Trial Essay -- essays research papers

The Black Sox Trial – 1921   Ã‚  Ã‚  Ã‚  Ã‚  The Black Sox scandal was a baseball betting scheme involving a group of baseball players and gamblers which led to the Chicago White Sox intentionally losing in the 1919 World Series. As a result this scandal led to the banning of eight players from the 1919 Chicago White Sox team, Joe Jackson (better known as Shoeless Joe Jackson), Eddie Cicotte, Chick Gandil, Oscar Felsch, Fred McMullin, Swede Risberg, Buck Weaver, and Claude Williams. This event also introduced a new commissioner and strict rules prohibiting gambling in baseball.   Ã‚  Ã‚  Ã‚  Ã‚  This conspiracy was the innovation of the White Sox’s first baseman Chick Gandil and Joseph â€Å"Sport† Sullivan, who was a professional gambler among his friend circle. During the 1919 baseball season, the Chicago White Sox had proven themselves to the world that they were the best team in the baseball league and, having clinched the American League pennant, were installed as the bookmarker’s favorites to defeat the Cincinnati Reds in the Series. At the time, gambling on baseball games was widespread and there were numerous stories about rigged ball games during the regular season but they were generally ignored by the team managers and owners.   Ã‚  Ã‚  Ã‚  Ã‚  Gandil, the first baseman, recruited seven of his teammates, to instigate â€Å"the fix,† all which was motivated by the mixed feelings of the dislike of the club owner Charles Comiskey along with greed. The seven players were the starting pitchers Eddie Cicotte and Cluade â€Å"Lefty† Williams, outfielders Shoeless Joe Jackson and Oscar â€Å"Happy† Felsch, and infielders Swede Risberg, Buck Weaver, and Fred McMullin. Sullivan and his two acquaintances Bill Burns and Billy Maharg contacted a wealthy New York gambler by the name of Arnold Rothstein to supply the money for the 8 players, who were told that they would get a total of $100,000. Even before the infamous Series started on October 1st there were whispers all over amongst the gambling population that things were a little weird, and the flood of money showed the odds of Cincinnati decline rapidly. These rumors also reached the press box where a number of reporters, including Hugh Fulle rton from the Chicago Herald along with Examiner and ex-player and manager Christy Mathewson, got down to compare notes on any plays and or players... ...ear. As it turned out the 1917 win in the World Series was the last championship the Chicago White Sox ever came across; changing the American pastime history forever! This Black Sox Scandal trial was a very interesting trial I had wanted to know about for the longest time. In writing this paper I mainly referred to the site,  Ã‚  Ã‚  Ã‚  Ã‚  http://www.law.umkc.edu/faculty/projects/ftrials/blacksox/blacksox.html This site consisted of many useful links and was very informative and broke down the events leading up to the trial and gave the entire sequence of events in a brief. Furthermore, to my surprise this site provided the court documents like the confessions of Joe Jackson, which seemed to be lost for a while and then mysteriously surfaced out of the blues later on, the trial testimonies, and many more. What really helped me out was the chronology of events along with the diagram of â€Å"the fix†. It was a lot easier to follow the diagram in my opinion. Another link on the website I found quite useful was â€Å"The Eight Men Out† link. It appropriately gives the ages, positions, salaries, and comments Gandil made for the eight players which were accused of the scandal.

Polk Jefferson Expansion Essay

There have only been a few presidents that have expanded on the size of America. None have done it like Jefferson and Polk. Though they had different views on the world they had many of the same policies of expansion. Both technically bought the land. At the times both of their practice's were considered shady. Jefferson and Polk both also were afraid of foreign powers swooping down and taking the land. When you are a president it is always good to appear fair and diplomatic. This is why the presidents wanted to buy the land. Thomas Jefferson bought his land from France in the famous Louisiana purchase. It was a bargain brought on the table by France for many differing reasons. Polk on the other hand fought Mexico in a war. Then once he owned the land gave them only a portion of what it was worth. He had leverage over the Mexicans because he had crushed their armies in the Mexican war. Its hard to escape the presidency without some scandal. Polk and Jefferson both could not accomplish this. Jefferson bought the Louisiana purchase from France. Even though he believes and, at the time it was widely believe he shouldn’t have that power. Polk’s on the other hand was more substantial. He sent troops into either America, Mexico or, the disputed territory and they were ambushed prompting the war. If the troops were in the disputed territory then they might declare war. If they were in Mexico what Polk did was illegal. IF the troops were in Texas then it is all out war. Polk never clarified where the troop were to we may never know. During Jefferson’s and Polk’s presidencies America wasn’t really a world power. So when America got the chance to take land they took it quickly. Jefferson when offered the Louisiana purchase acted quickly so the French might not change their minds or some other country would take the weakly guarded land. Polk also was afraid that the Russians or the British might swoop down and take California. Something Polk couldn’t afford. Both Jefferson and Polk are regarded as fantastic presidents in today’s light. Both had to make the expansion legal by buying the land. Both had their fair share of scandal and, both had to beat out other nations for the prize. This just goes to show according to history expansionism is usually a good thing.

Impressionist’s Gender Roles Essay

Manet’s Olympia (circa 1863) is a classic example of the reclining nude. This appears to be a private space as there is an attending woman included in the painting. In contrast to this Berthe Morisot’s landscape painting is a public piece, depicting people on a promenade. For Manet’s painting, the viewer relates in a blatant voyeuristic way, gazing upon the nude just as the nude gazes back at the viewer in a poised repose. Morisot’s painting is striking because she depicts women out and about, not confined to a garden persey, but out in the open (two women and a small female child). In both paintings, the women depicted appear to be of high class, since the woman in Manet’s painting has a servant and the two women in Morisot’s painting have parasols indicating that they have enough money for accoutrements. Manet’s painting is a classic gaze painting, meaning there are tones of voyeurism but that the subject gazes back at the viewer with her head held high as though she were not indeed naked. In Morisot’s painting, there is a marked distance between the subjects and the viewer allowing the viewer more freedom to gaze upon these women and their stares do not penetrate the canvas back toward the viewer. It is interesting to note that Manet’s painting depicts a nude woman who stares blatantly back at the viewer while Morisot’s painting depicts clothed women who do note even recognize the viewer’s presence into their world. Thus, the difference between and male and female painters is taken note of in this instance: The female painter does not allow her subjects to look back while the male painter has a fully nude woman strongly gaze upon the viewer.

Free Essays on Greek Myths

Greek Mythology In order to explain certain natural events, such as earthquakes, windstorms, and thunder and lightning storms, The Greeks invented a collection of myths and characters. Just as with most modern religions, Greek Mythology bases most of it’s myths on morality and ethics issues. Unlike Egyptian Mythology, the Greeks did not focus on what was going to happen in their afterlife. They were more concerned with the here and now. There was no written special commandments in Greek Mythology. The Greeks did, however, base most of their moral and ethical ideals on the Iliad and the Odyssey, both written by Homer. In his work, Homer says that man holds his own fate in his hands. He portrays that wrath will cause much suffering, pain, and even death. Homer formed the fundamental attitude of the Greek mind. He established the foundation of excellence for all aspects of life, and the Greeks put these into their reality. Nothing was known about Homer or any part of his life, so the question ar ises as to whether Homer was a single individual or was he, in actuality, a collection of authors. The Greeks had a polytheistic culture. Unlike the religions of other ancient civilizations, the Greeks created the gods in their own image. They were holy deities that could make contact with humans, often in a disguise. The gods had the same desires and weaknesses as human beings and the myths often portrayed them as lustful, greedy and vengeful. There was no holy place that the Greeks went and prayed to the gods. Instead, the temples that were erected, were for the gods to come and visit. Festivals were often held to praise the gods. During these festivals, no war could be fought. The gods spoke to humans through oracles and people often went to these oracles for advise on what the gods wanted. The gods were used to explain whether humans would have great fortune or hardships.

Alice in Wonderland is a book that appeals to children and adults Essay

Alice in Wonderland is a book that appeals to children and adults alike - Essay Example The first element that will appeal to children is the fact that the main character in the book is a child. Children appreciate being told stories in which a girl or boy of their age-group are the protagonist. Also, while few children today will completely understand the situation of a Victorian school-girl, they will appreciate and perhaps even empathize with feeling bored when there is nothing else to do. Every child would love for the games they play within their imagination to magically come to life as they do when she hears a rabbit say "oh dear, oh dear, I shall be late" and then its action in taking "a watch out of its waistcoat pocket" (Carroll, 1992). There is an immediacy and vivid nature to the Carroll's descriptions of both animals and events within the story that appeals to children. While what occurs in the story can seem quite complicated at times, especially compared to many more modern children's stories, they are also recounted in a concrete and memorable manner. The various animals that appear in the pool of tears, the Cheshire Cat, the animals at the tea-party and the various creatures in the game of cards are all described in a way that will appeal to children. ... Thus the shrinking and enlarging that she undergoes, together with her various other adventures, introduce the children to the constant changes that occur in the book In many ways the children may be attracted to the story because it reflects their own experiences while dreaming and day-dreaming. The manner in which the story develops with the insane croquet game and the rather violent Queen who wants to execute all and sundry for the smallest of supposed transgressions appeals to children because they appreciate stories that may disturb them if not outright frighten them. Children do not appreciate being talked down to, or being presented with a sugar-coated view of the world that is not realistic. Carroll does neither. He presents a strange and exotic fantasy-world in which Alice can play croquet (or at least try to) with a flamingo and a hedgehog. This is a "fun" idea which nevertheless presents a rather bizarre view of the world. One of the most remarkable features of this world is the manner in which there is apparently no sense of morality within the book. The Queen states "off with his head" at the slightest provocation, even to the Cheshire Cat who is, of course, only a head when he appears at the croquet game. Carroll does not fall into the tendency of many children's books to moralize, he rather presents an amoral world in which things occur at random. The Cheshire Cat appears and disappears for no apparent reason, and refuses to play into the supposed social order of this world. So when the King says "it may kiss my hand, if it likes", the Cheshire Cat replies "I'd rather not" (Carroll, 1992). This exchange might be seen as a microcosm of

Womens Leisure Essay Example | Topics and Well Written Essays - 750 words

Womens Leisure - Essay Example However, derby is popularly known as a type of rough contact sport. This is the reason why both male and female players may allow themselves some form of violence, roughness or even cheating strategies if they believe they have to win. At my school, athletes are perceived as physically healthy individuals and ones who are popular among members of the opposite sex. Moreover, the girls’ and boys’ athletic programs are usually perceived as a way for athletes to improve not only their physical health but also their self-esteem and popularity. Personally, I watch men’s professional sports more than women’s, especially basketball as NBA is more exciting to me than WNBA. It is hard to say why but as a man who is into basketball myself, I would usually prefer watching men play sports than women do it. Perhaps, it is the relatively higher level of aggression in men’s professional sports that makes them widely watched compared to women’s. Nevertheless, occasionally I am amazed whenever I see a woman doing a man’s job, especially when professional female athletes get to be really rough on the field, in the court or in the ring. Sports are basically all about competition, and so people are expecting a good and rough fight. This is akin to something that will maintain the adrenalin rush. This is also the same feeling the Romans perhaps once had while watching gladiators kill each other at the bottom of the Colosseum more than two thousand years ago. When it comes to the movie Whip It, Bliss seems to show doubt about trying out for the derby team because she herself is an indecisive woman with no idea about what the future would bring her. Moreover, she does not believe her mother Brooke would be proud of her if she played derby. Brooke wants her to be a beauty contestant like her in the past. Moreover, Bliss may be hesitant at attempting to do derby. This is because she knew that in order to be a professional derby player, on e has to be extra tough although one is female. She may have observed this since the first time she saw the Hurl Scouts and Holly Rollers played. Bliss and Brooke are very different from each other when it comes to leisure and recreation. Brooke likes shopping and is into beauty contests and other activities that bring out the refined woman in her. She views herself as usually right in her decisions, opinions and perspectives. Nevertheless, she shows her humility and love as a mother. This is evident when she tells Bliss that the latter need not join the Blue Bonnet pageant if she is only doing it for her mother. On the other hand, Bliss is into professional derby, men like Oliver, and something that will bring out the best in her. Bliss’ desire to bring out the best in her somehow translates as a desire to join the hurl Scouts and defeat the Holy Rollers. Little does she know that it is one way for her to prove her own worth to herself. In the process, she also indirectly pr oves to her mother that she can make decisions of her own. Nevertheless, at several instances in the movie, Bliss does not feel that she is making the right decisions. Thus, compared to her mother, who is righteous most of the time, Bliss shows some indecisiveness. Furthermore, perhaps this is the same way Bliss views herself at the beginning of the movie – a young woman with no direction. This view, however, changes in the end as her mother accepts her decision to be on the professional derby team. This is also the point where Bliss realizes her calling (Barrymore). The way I see it, Brooke is just the strict, conservative mother that mothers are supposed to be. On the other hand, Bliss is the picture of an ordinary girl who defies her own parents’

Juvenile Recidivism Essay Example | Topics and Well Written Essays - 1250 words - 1

Juvenile Recidivism - Essay Example The designing of effective assessment strategies leading to interventions with the young offenders are no doubt, predominantly dependant on the identification of causal factors that constitute the basis of a realistic prediction (Savitz et al., 1962). Adolescence is a phase of life when the young people are more prone to engaging in antisocial behavior. Practice of antisocial behavior during adolescence is the single most important factor in the prediction of criminal behavior in the adulthood. A plethora of research carried on till now has suggested that almost a half or more of juvenile offenders continue with the criminal behavior beyond their teens. Juvenile recidivism is a serious problem in the United States. On an annual basis, roughly 2.4 million juveniles are charged with criminal offences every year (Wilson, 2011: Online). As per some conservative estimates, roughly 55 percent or more of juvenile offenders who are released get rearrested within a year (Wilson, 2011: Online). In case of urban areas, the rate of juvenile recidivism is estimated to be as high as 76 percent (Wilson, 2011: Online). At a national level, it is utterly difficult to acquire the accurate recidivism rates. This is because in the US, the recidivism rates in case of juvenile offenders are assessed at a state or county level (Wilson, 2011: Online). Hence, the statistics specific to the particular states is in a way a realistic indicator of the levels of juvenile recidivism. In the year 2005, the rate of juvenile recidivism in the State of Washington, in case of boys stood at 77 percent and in the case of girls it stood at 72 percent (Wilson, 2011: Onli ne). In the State of California, the percentage of juvenile delinquents who got rearrested within a year was 74 (Wilson, 2011: Online). In Manhattan, the rate of juvenile recidivism rested at roughly 80 percent (Wilson, 2011: Online). Many

Merger Management of Kraft and Cadbury

Merger Management of Kraft and Cadbury Nowadays, organisations must actively develop and adapt appropriate changes that fit the dynamic environment. This highlights the importance of change management in judging how flexible and responsive an organisation is. As more companies expand and diversify, it is inevitable that smaller organisations are now looking into merger with bigger organisations to boost their share of their market. Bigger organisations are also attracted by the opportunities of entering untapped emerging markets. Therefore, the nature of change that we will be investigating in this report is merger and acquisition (MA). We will relate this change to USs Kraft Foods Incorporated, as the company recently acquired UKs Cadbury. The issues we have selected to focus on are in the following order: leadership and communication, cultural change, and staff resistance. Leadership is chosen because leadership is critical to determine the success of an acquisition. Firstly, due to the huge number of employees involved, the choice of an appropriate leadership style is vital to ensure integration in both companies is a smooth process. Next, an effective leadership will improve the productivity of both companies through the efficient allocation of resources to achieve the organizational strategic goals. Communication is chosen because the acquisition will raise doubts among Cadburys employees on their roles in the new company and its vision and goals. The feeling of uncertainty about their future could lead to a dip in their morale and low productivity at work. Thus, it is essential for Kraft to use an appropriate communication strategy to increase the awareness of the employees of any impending change initiatives. Culture is chosen because of the diverse cultures between Kraft and Cadbury. Cadbury was founded on Quaker ethics to build a socially benign business. This philosophy helped Cadbury to build a world-class brand that is close to the hearts of the British people. In contrast, Kraft is more of a performance driven company with decades of profit driven mergers and demergers. Thus, it is essential for Kraft to identify and value the cultural differences as sources of synergy and efficiency in order to manage the acquisition process effectively. Staff resistance is chosen because management and employees made up the core structure of the organisation. The policies undertaken by these personnel and behaviour exhibited can have an immediate and vital impact on determining how organisation functions. In the horizontal acquisition of Cadbury, Kraft must also be able to seek equilibrium for integrating the staff from both sets of organisation. Conflicts at management levels, diverse working styles and even motivational approaches are some situations that may hinder and pose challenges. Before implementing any change initiatives, we recommend Kraft to conduct diagnosis of the three issues mentioned above. 2.0 Leadership and Communication 2.1 Definition of Leadership Koontz and ODonnell (1955, pg 17) the activity of persuading people to cooperate in the achievement of a common objective 2.1.1 Adairs Action Centred Leadership Duberly (2010) Adairs Action Centred Leadership model points out that a leader can only be successful when he is able to meet all three areas of needs task, individual and team maintenance needs- by helping his followers achieve the objectives of the common tasks, generate team dynamics and cater to the individuals needs. 2.1.2 Case-Study Rebecca Johnson (2008) The case study of Refresh Yourself illustrates Britvics use of Adairs action centred leadership to revive their company. For meeting task needs, the use of the balanced scorecard system with job descriptions provided their employees with a clearer understanding of their duties and responsibilities. With that, it helped to set the direction for employees to achieve their objectives. For meeting individual needs, the use of a performance management system with a core set of behaviours allows the employees to know how effectively they are performing relative to expectations. With a performance-based rewards system, Britvic motivated their employees by rewarding them accordingly as a form of recognition. For meeting team maintenance needs, a workshop session was conducted for the leaders of Britvic to reflect on their leadership. The insights gained proved to be very beneficial to them in their role as a leader as survey results showed that the employee engagement increased from 55% to 70% and employees confidence in leadership leapt to 72%. 2.1.3 Recommendations For meeting task needs, Kraft needs to provide a detailed road map which includes specific and clear goals, a detailed approach for achieving these goals, and a list of resources and time required to reach these goals. With that, Kraft and Cadbury can identify common goals so that the employees from both companies can work together on common projects in order for a smooth integration to occur. In the case of Kraft, the closure of Cadburys Somerdale plant led to a loss of 400 jobs. This caused the Cadburys employees morale to decline as they were fearful of further jobs losses. More importantly, this caused a loss of trust in the leadership of the organisation. Thus, Kraft should make a pledge to them that there will be no further job losses and factory closures to assure them of their job security. This form of assurance will restore their morale and bring about greater productivity within the team to meet the team maintenance needs. For meeting individual needs, Kraft should acknowledge employees achievements by offering rewards to keep them motivated. The rewards can be offered in the form of the cafeteria rewards system which offers employees the ability to choose a combination of benefits that best suit their needs. 2.1.4 Transformational Leadership Bass, B. M. (1990) There are four factors which make up a transformational leader, namely, charisma, inspiration, intellectual stimulation and individualized attention. Firstly, a transformational leader exudes charisma and instils pride in employees within the organisation. He creates vision to guide his followers and as engines of change within the organisation. They are deemed as role models. Secondly, a transformational leader communicates optimism about future goals to inspire his followers. Thirdly, he uses intellectual stimulation which encourages innovation and creativity in approaches towards identifying and solving problems. Lastly, he shows individualized attention by addressing his followers concerns and providing them with training for self-development. 2.1.5 Case-Study Catherine Monthienvichienchai (2007) The case study of Korea Ladder illustrates how Jonathan Cormack took on the role of a transformational leader. He united the two organisations behind a shared vision to inspire his employees. They were placed in groups for a discussion to help them realise the shared vision. He also fostered workplace creativity by conducting workshop sessions which were not a common practice in a Korean workforce. It was used as a form of intellectual stimulation to instil a sense of belonging in the employees. The positive feedback received from the employees proved that it was a success. He showed individualized consideration for the staff when he convinced the union that the foreign executives should not be removed as their experience and strengths possessed were essential to bring the bank to the next level. 2.1.6 Recommendations As the acquirer, Kraft needs to unite the two companies under one vision by offering communication programs that support the shared vision. The programs can be in the form of workshop sessions which creates a participative environment to foster a sense of belonging and involvement among employees. This environment would enable Kraft and the employees to work out a mutually satisfying outcome (i.e. a win-win situation). Next, Kraft must work at gaining the trust and respect of Cadburys employees to prevent the defection of talented people. Kraft can do so by bringing talents from both organisations together to work jointly on projects. This will encourage employees to focus on their similarities rather than their differences.The organisations various departments need to be restructured and processes must be redesigned to align with Krafts vision. 2.2. Communication 2.2.1 Definition of Communication Newman Summer (1977, pg 12) Communication is an exchange of facts, ideas, opinions or emotions by two or more persons. Communication Process Duberly (2010) Communication begins when the transmitter encodes a message to convey an idea, the receiver then decodes the message to achieve understanding. The context of a message refers to the non verbal cues conveyed by the transmitter to the receiver. The perceptual filter actually influences the way the message is transmitted. It ends with the receiver providing feedback to the transmitter to evaluate the effectiveness of the message. For effective communication on change, we will focus on three communication strategies. Firstly, spray and pray is used when employees are showered with a wide variety of information, and managers pray that staff will pick up what is needed to be done. Secondly, tell and sell is used when management attempts to both inform employees on changes and sell them on why they are required to the passive employees. Lastly, underscore and explore is used when management engages employees in a dialogue about the change process and seeks to identify obstacles and the misunderstandings that need to be addressed. Lastly, withhold and uphold is used when information is withheld until it is absolutely necessary to release it. 2.2.2 Case-Study Sarah Butcher (2005) The case city of Recovery plan illustrated the use of tell and sell as a communication strategy to persuade the bankers at Citigroup to be receptive to the new performance appraisal and compensation system. With regards to the revised compensation system, Citigroup need to sell to their bankers the idea that bonus payout will not be solely based on reaching financial targets but also dependent upon comprehensible understanding of the shared responsibilities. Another communication strategy adopted by Citigroup was spray and pray in educating their employees on the ethics and the banks code of conduct. It is a top down and one way communicating approach as the responsibility of communicating the acquired knowledge to the rest of the employees falls on the shoulder of 3000 senior employees at Citigroup. 2.2.3 Recommendations For effective communication, Kraft can adopt the underscore and explore method whereby they conduct a transparent and truthful dialogue with the employees to address the differences in culture and to identify any constraints for the change to be implemented. Kraft can also go beyond reassuring the Cadbury employees of their motive regarding the closure of the Somerdale plant. Since this is a two-way communicating process, the feedback generated from the active employees will be useful in resolving misunderstandings and build consensus on key issues. Kraft has to be cautious especially when dealing with redundancies. The communications, compensations, and benefits for redundant workers need to be clear and direct so as to build trust and commitment. In addition, they should also take a closer look at the effects of survivors (remaining workers) who suffered from low morale and decreasing commitment, trust and loyalty towards the organisation after the merger. Kraft can being by educating and persuading survivors of their good intentions by accounting personally for their action. On the other hand, the survivors need to be informed of their specific job roles and entitlements. Unless companies try to deal with this survivor syndrome by demonstrating to the remaining employees that the process for determining redundancies was transparent and professional, and those made redundant were treated fairly and lawfully, the general productivity and morale are less likely to be affected adversely. 3.0 Cultural change 3.1 Definition of Culture Drennan (1992) defined organisational culture as, Culture is how things are done around here. It is what is typical of the organisation, the habits, the prevailing attitudes, the grown-up pattern of accepted and expected behaviour. And as aptly phrased, culture is the key factor for making or breaking a merger and acquisition dealÂÂ ­. (Accenture, 2000) 3.1.1 Understanding Organisational Culture To better understand organisational culture, different methods are used, one being the Onion skin (Duberley 2010, modified from Schein 1992, 2004) Schein suggests three levels to organisational ÂÂ ­ structure: artefacts (e.g. language, environment, rituals), espoused values (organisations strategies, goals, philosophies) and basic underlying assumptions level (subconscious perceptions, thoughts and feelings that are the ultimate source of values and actions). Onion Skin (modified from Schein) 3.1.2 Sources of Organisational Culture The founder, organisational history, industry and size of the organisation impact its culture. (Duberley, 2010) Organisational culture is also reflected by national cultures and professional subcultures. (Hofstede, 1981) 3.1.3 Influence of National Culture The difference in various elements of a country such as languages, laws, values and attitudes will lead to one nations culture diverging significantly from another (Hofstede, 1980; Tayeb, 1989; Wilson, 1992) As an example of national culture, Adler (1997) describes Americans strong individualistic tendencies evidenced in their language such as trounced the opposition, and their human resource management based on individual knowledge and skills. (Calori and De Woot, 1994; Hemel Hempstead: A European Management Model Beyond Diversity), we understand that though organisational culture in the United Kingdom has similarities with the United States, certain significant differences include the adversarial relationships with labour, the tradition of the manager as a gifted amateur (as opposed to the professionalism of US managers) and the influence of class differences in the firm. 3.1.4 Cadburys and Krafts Culture Cadburys culture stems from its founder of Quaker origins: a paternalistic and philanthropic culture, which also focuses on the well being of groups rather than the individual. This translates to the idea that the leader knowing what is best for the organisation and its followers: (i.e. leaders as expert father figures). Cadburys culture of principled capitalism is what makes Cadbury great and it has successfully built a socially benign business. Cadbury has a loyal workforce that consists of staff and managers who have been in the organisation for a long period. Cadbury has a long tradition of high quality production and most of its factories make use of its local community, thereby ensuring that the brand itself is close to the hearts of locals. What this translates to is a family orientated and communal working atmosphere where staff takes strong pride in their work. Krafts culture is more performance oriented and is more focused on the meeting of sales and performance goals. Kraft is the quintessential traditional multinational business firm. There is a mercenary culture present; most staff and managers perform in relation to the rewards they get. Most rewards they expect are material and on an individual basis. Furthermore, Kraft is very much interested in destroying competition and seeks many alternatives and ways to ensure they are always ahead of competitors. Krafts culture is less communal and the working atmosphere is unlike a family atmosphere, in that people view each other as merely working colleagues and do not share deep friendships with one another. Staff and managers in Kraft are productive and focused in their work and most of them have a passion for business. 3.1.5 Potential of Post-Acquisition Culture Clash The acquisition will damage Cadburys current culture as the striking differences between Cadbury and Krafts culture may damage Cadbury existing successful culture of principled capitalism. This would bring about lower morale and performance and de-motivated staff. Krafts competitive and goal orientated culture might cause staff burn out amongst the Cadbury employees as they may feel insecure and uncertain. Krafts mercenary culture may create a lack of trust, which will weaken Cadbury staffs strong loyalty. By joining an American company, Cadbury risks losing UK benefits schemes to American procedures. Also, consumers may feel betrayed by the loss of its original organisational goals, resulting in a weakened brand. However, one advantage is that Cadburys shareholders will profit through the acquisition with the worlds second largest food manufacturing company. 3.1.6 Case-Study (Quote your Reference)SCB (an America-originated company) acquired and merged with KFB. SCB was successful with the merging of cultures due to effective communication, the understanding of the differences in cultures and the understanding that If you dont stretch things at all then nothing will change, but if you stretch things too far or too fast youll leave people behind. The approaches SCB used were the Conciliative, Educative and Corrosive approach, evidenced in the heavy use of consultation, training and use of networking. With this, they successfully overcame problems of national culture and cultural change such as: over-enthusiastic labour unions and differences in management styles, to name a few. What Kraft and Cadbury can learn from this is the importance of communication and flexibility in the use of approaches. 3.1.7 Recommendations Because culture is an essential element in an organisation, culture analysis should play a major role in an acquisition. Both qualitative and quantitative analysis exists in corporate culture: visual artefacts or manifestations of the organisation, the espoused values and basic assumptions (The Onion skin model) of the organisation have to be properly evaluated. This is essential to better understand the Krafts inner-workings and most importantly, its employees and their feelings toward the acquistion. The difference in national cultures of a UK in comparison to US organisation also impacts organisations greatly. Thus, Kraft should exercise patience and understanding to ensure that culture change is implemented and not resisted. (Whittle et al (1991:3) We understand that culture change is not a single event but an ongoing sequence of changes. Flexibility is important, as different stages of the change program may require appropriate approaches. 4.0 Resistance and Resentment Felt by Cadbury Employees 4.1 Definition of Individual and Change We will be illustrating the definition using case-study of the acquisition of Cadbury by Kraft. The process involves organisation undergoing a transformative change. This is so as the nature of change is large-scale and fundamental. At the same time, the effect is permanent and can be observed in the long-run. This issue raises the question of uncertainty which in turn, brought about greater anxiety. According to Schein E. et al. elaboration on Kurt Lewins(1951) Three-Step Model, anxiety can be broken down to two major forms survival and learned anxiety. The former pushes for change while the latter obstructs change. In order to integrate the change, Scheins theories suggest an inclination towards minimizing the learning anxieties. Generally, there are three areas we will be investigating with regards to the case-study. Firstly, the consideration of parochial self-interest which will need us to look into how the various groups in organisation will react upon their immediate interests in the company. With a likely shift in management, Cadbury staff will be reassigned to new job roles and positions in Kraft Inc. this may affect the individuals and probably also management. A possible reshuffling of manpower by HR will see the Cadbury staff go through a series of re-employment tests to allocate them to suitable tasks. This means that potential loss of authority and power especially for the executives and leaders of Cadbury relevant to their positions resulting in a conflict between their self-interests and the organizations interests. Therefore, the move to quit by the staff may be explained by this clash of interests. Next, the misunderstanding may be another consideration since the top management could be inconsistent in conveying their messages while middle-level managers could have failed to communicate clearly and on a constant basis to employees. They may put off the delivery of what they deemed as negative news. At the same time, employees are interpreted to be in denial and avoid the truth. They are sceptical of success and are unwilling to move out of their comfort zone to embrace change. Lastly, the tolerance for change is low as the former Cadbury staff may take huge pride in how they go about doing their work. Kraft personnel think otherwise and what they thought to be desirable for the organisation could be in contradiction with the new staff. The former Cadbury staff may reject changes while Kraft personnel likewise will stick to their ways of carrying out tasks. We will look into the Model of Stages of Psychological Reaction by Hayes and Hyde (1996) adapted from Elizabeth Kubler-Ross(1969) and see how it affects the individual change of Cadbury worker. Model of Stages of Psychological Reaction When Kraft Inc. based in the America announces the acquisition of UKs Cadbury on February 2010, there was first, feelings of shock among the stakeholders and also the employees of both companies as the ongoing speculation has been realized. Upon the acquisition of Cadbury, subsequently Kraft drew up plans to smooth the process of integration of the UK-based competitor into the confectioner family. However, at this stage the general sentiments among the people involved are denial. The employees may find it difficult to come out of this particular stage. Implementation of the changes to the different levels of organisation as Kraft begins to incorporate and find a fit for the new employees, new teams and new managers. At this stage, employees may experience depression and letting go but the main idea is that most personnel will not be able to come out of the previous stage so they will have regress or stay put in the previous phase. Thus, not all will complete this cycle. Some may progress beyond and enter the acceptance and testing stage which we believe to consist of majority to be the lower level of staff and employees while the senior management figures most probably regress or stay in the denial stage or even move on to another company highly likely for the case according to the article 120 of 165 Cadbury Staff Leave Since Krafts Takeover on webpage http://www.foodanddrinkdigital.com/sectors/food-manufacturing/120-165-cadbury-staff-leave-kraft-takeover. Case Study (Quote your reference) In January 2005, Gillette was acquired by PG. The merger resulted in around 6000 job cuts which was equal to 4% of the combined workforce of the two companies. The process of post-merger integration of these two companies faced an inevitable resistance. A number of people were told that they had joined what they thought was a long-term employer with sufficient size and famous brand. They felt that Gillette was a leader in the industry on many fronts. Not only were some Gillette staff personally unprepared for the takeover, because they often felt that their company was the better one, they also did not believe in the tremendous opportunities that were promised by top management from PG. Gillette employees had to face the unpleasant dilemma of whether moving to PG (and coming to terms with the changes) or leaving the company. PG and Gillette essentially had two different corporate cultures. Employees of Gillette hoped that Gillette, because they had been so large and successful, would be able to influence PG post-acquisition. But hoping for that was a complete utopia, as one former employee said. Gillette was absorbed into PG and very little from its culture was left, another said. Rather than change, employees voluntarily but reluctantly left the jobs they thought they would have until retirement. (Quote your Reference) In a joint press release at the time of their merger in 1997, the president of Daimler-Benz, JÃ ¼rgen Schrempp, and the president of Chrysler, Robert Eaton, declared that there will be no plant closures or layoffs as a result of the merger. However in 2000, the company announced there would be between 20000 and 40000 job cuts in the North American Chrysler division. Schrempp, by then the DaimlerChrysler president, claimed that the company was overstaffed by at least 6%. Announcing redundancies two or three years after the initial deal can cause even greater stress to the employees who thought that they were survivors. Employees are better prepared to handle the bad news straight after the transaction than two years later, after the newly merged culture has started to take shape when they thought they could rely on managements assurances regarding the merger, often accompanied, as in the Daimler/Chrysler example, with promises of no future redundancies. 4.1.2 Recommendations The negotiation and agreement approach would be much recommended. The resistance stems from Krafts inability to walk the talk of retaining the Somerdale plant in operation. On top of walking the talk, they are expected to keep behaviour consistent with messages, keep commitments and promises, and demonstrate some energy and enthusiasm regarding the change. Only then will team members feel they can take the next step of commitment. Kraft has to deploy the soft power to facilitate integration between the two cultures. The soft power provides an effective mean for Kraft to reach out to employees at a personal level. This promotes the establishment of a long-term positive relationship as empathy and communicating at employees level builds trust and strengthens their commitment to the organisation. 5.0 Conclusion In view of the acquisition of Cadbury, it is critical for Kraft to establish an effective leadership team to pave the way for a change programme. Kraft can adopt Adairs action leadership to have an overview of the three areas of need and ensure that they are met adequately. The success of the acquisition is also influenced by how well Kraft communicates to their employees on the change. Thus, Kraft should use the underscore and explore method to address the possible challenges and problems caused by culture differences. Due to the diverse cultures of Kraft and Cadbury, onion skin method can help Kraft identify the differences to prevent culture clash. With this in mind, Kraft can set directions for the management and employees to realign their styles of working to fit the companys vision. This will pave the way for Kraft to achieve their objectives and develop a strong standing corporate culture at the same time. Effective HR management may be a viable solution but in the long-run, in order to foster a harmonious relationship and spirit of unity among the management and employees. It is necessary to inculcate positive employee attitudes and promote willingness to learn with the acceptance of changes. Eventually, the organization can help staff to align their interests with those of the company so as to keep motivation high level across all departments. 6.0 Appendices 6.1 List of References References for Leadership Communication Type of Source Reference List Reference Books Bernard M.

Applications of Prisms and Math :: Mathematics

Missing Figures Prisms and their Applications Introduction A prism is one or several blocks of glass, through which light passes and refracts and reflects off its straight surfaces. Prisms are used in two fundamentally different ways. One is changing the orientation, location, etc. of an image or its parts, and another is dispersing light as in a refractometers and spectrographic equipment. This project will only deal with the first use. Consider an image projected onto a screen with parallel rays of light, as opposed to an image formed by the same rays that are passed through a cubic prism (assume that the amount of light that is reflected is negligible). The rays that pass through the prism will not be refracted since the angle of refraction = sin-1(sin(0)/n) = 0, or reflected, so the images will be exactly the same. More generally, if the rays enter and leave a prism at right angles (Assuming the rays only travels through one medium while passing through the prism), the only effect on the image will be the reflection of the rays off of its surfaces. Since the law of reflection I= -I’ (Angle of incidence equals the negative of the angle of reflection) is not effected by the medium, the effect of the prism will be same as that of reflective surfaces or mirrors placed in the same location as the reflective surfaces of the prism. It follows that to understand prisms it is important to understand how mirrors can be used to change the direction of rays. Mirror Location Problem 1: Consider the following example: A horizontal ray is required to undergo a 45Â º-angle change and this has to be achieved using a mirror. We need to find how the mirror should be oriented to achieve the desired change of angle. Solution: Recall the Snell’s law which deals with refraction: sinI0 /n0 = sinI1/n1 if we define the incoming and outgoing rays ray and the normal of the refractive surface as vectors and using a property of the cross-product we can say the following Q0xM1 = |Q0||M1| sinI0 = sinI0 and also Q1xM1 = |Q1||M1| sinI1 = sinI1 thus N0 (Q0xM1)= n1 (Q1xM1) If we introduce two new vectors S0 and S1 and let them equal n0 Q0 and n1Q1 respectively we will get S0x M1 = S1xM1 or (S1-S0)xM1 = 0 this implies that (S1-S0) are parallel or anti-parallel, which means that we can define a new variable Γ which is called the astigmatic constant with S1 – S0 = ΓM1 How is useful for solving our problem?

How michael porter five model affects Costco Wholesale Corporation Essay

According to Michael Porter, an industry is affected by certain forces, which enable them to attain different levels of profitability. These five forces help managers analyze the industry to gain a better understanding and develop a more effective business strategy. In the discount retailing industry, it is important to consider the following when considering entry: Threat of New Entrants: Four major competitors, WalMart, Kmart, Target and Costco Wholesale dominate the discount retail industry. The threat of new entrants is low, as this small number of large firms has spent decades establishing their position in the market. While online retailers, such as Amazon.com, and smaller department stores do create a semi-competitive environment, there is no major threat as the entry barriers are high (there is major risk and expensive start-up costs) and small start-ups are discouraged from trying to penetrate the market. The lack of patents and government regulation allow the existence of small department stores in the industry, but their expansion is limited. Rivalry Within the Industry: In the discount retail industry, there is fierce competition among the major brands, as products sold are usually relatively price elastic; most of the shoppers are looking for the â€Å"best value for price† and the goods are not significantly differentiated from one another. This leads to efficient management and competitive costs. While dollar stores and other small retailers have established a niche market, they do not pose a significant threat to the market leaders. Supplier Power: The existence of a large number of suppliers and limited shelf space has lead to low supplier power; retailers like Kmart are free to switch to alternate, cheaper brands. Threat of Substitutes: In terms of brand identity, the main players attempt to differentiate themselves from each other by emphasizing on their strengths; while WalMart is known as the price leader, Target

Classification-Based Data Mining Approach For Quality Control In Wine Production GUIDED BY: | | SUBMITTED BY:| Jayshri Patel| | Hardik Barfiwala| INDEX Sr No| Title| Page No. | 1| Introduction Wine Production| | 2| Objectives| | 3| Introduction To Dataset| | 4| Pre-Processing| | 5| Statistics Used In Algorithms| | 6| Algorithms Applied On Dataset| | 7| Comparison Of Applied Algorithm | | 8| Applying Testing Dataset| | 9| Achievements| | 1.INTRODUCTION TO WINE PRODUCTION * Wine industry is currently growing well in the market since the last decade. However, the quality factor in wine has become the main issue in wine making and selling. * To meet the increasing demand, assessing the quality of wine is necessary for the wine industry to prevent tampering of wine quality as well as maintaining it. * To remain competitive, wine industry is investing in new technologies like data mining for analyzing taste and other properties in wine. Data mining techniques provide more than summary, but valuable information such as patterns and relationships between wine properties and human taste, all of which can be used to improve decision making and optimize chances of success in both marketing and selling. * Two key elements in wine industry are wine certification and quality assessment, which are usually conducted via physicochemical and sensory tests. * Physicochemical tests are lab-based and are used to characterize physicochemical properties in wine such as its density, alcohol or pH values. * Meanwhile, sensory tests such as taste preference are performed by human experts.Taste is a particular property that indicates quality in wine, the success of wine industry will be greatly determined by consumer satisfaction in taste requirements. * Physicochemical data are also found useful in predicting human wine taste preference and classifying wine based on aroma chromatograms. 2. OBJECTIVE * Modeling the complex human taste is an important focus in wine industries. * The main purpose of this study was to predict wine quality based on physicochemical data. * This study was also conducted to identify outlier or anomaly in sample wine set in order to detect ruining of wine. 3. INTRODUCTION TO DATASETTo evaluate the performance of data mining dataset is taken into consideration. The present content describes the source of data. * Source Of Data Prior to the experimental part of the research, the data is gathered. It is gathered from the UCI Data Repository. The UCI Repository of Machine Learning Databases and Domain Theories is a free Internet repository of analytical datasets from several areas. All datasets are in text files format provided with a short description. These datasets received recognition from many scientists and are claimed to be a valuable source of data. * Overview Of Dataset INFORMATION OF DATASET|Title:| Wine Quality| Data Set Characteristics:| Multivariate| Number Of Instances:| WHITE-WINE : 4898 RED-WINE : 1599 | Area:| Business| Attrib ute Characteristic:| Real| Number Of Attribute:| 11 + Output Attribute| Missing Value:| N/A| * Attribute Information * Input variables (based on physicochemical tests) * Fixed Acidity: Amount of Tartaric Acid present in wine.

(In percentage) * Output variable (based on sensory data) * Quality (score between 0 and 10) : White Wine : 3 to 9 Red Wine : 3 to 8 4. PRE-PROCESSING * Pre-processing Of Data Preprocessing of the dataset is carried out before mining the data to remove the different lacks of the information in the data source.Following different process are carried out in the preprocessing reasons to make the dataset ready to perform classification process. * Data in the real world is dirty because of the following reason. * Incomplete: Lacking attribute values, lacking certain attributes of interest, or containing only aggregate data. * E. g. Occupation=â€Å"† * Noisy : Containing errors or outliers. * E. g. Salary=â€Å"-10† * Inconsistent : Containing discrepancies in codes or names. * E. g. Age=â€Å"42† Birthday=â€Å"03/07/1997† * E. g. Was rating â€Å"1,2,3†, Now rating â€Å"A, B, C† * E. g. Discrepancy between duplicate records * No quality data, no quality mining results! Quality decisions must be based on quality data. * Data warehouse needs consistent integration of quality data. * Major Tasks in done in the Data Preprocessing are, * Data Cleaning * Fill in missing values, smooth noisy data, identify or remove outliers, and resolve inconsistencies. * Data integration * Integration of multiple databases, data cubes, or files. * The dataset provided from given data source is only in one single file. So there is no need for integrating the dataset. * Data transformation * Normalization a nd aggregation * The dataset is in Normalized form because it is in single data file. * Data reduction Obtains reduced representation in volume but produces the same or similar analytical results. * The data volume in the given dataset is not very huge, the procedure of performing different algorithm is easily done on dataset so the reduction of dataset is not needed on the data set * Data discretization * Part of data reduction but with particular importance, especially for numerical data. * Need for Data Preprocessing in wine quality, * For this dataset Data Cleaning is only required in data pre-processing. * Here, NumericToNominal, InterquartileRange and RemoveWithValues filters are used for data pre-processing. * NumericToNominal Filter weka. filters. unsupervised. attribute. NumericToNominal) * A filter for turning numeric attribute into nominal once. * In our dataset, Class attribute â€Å"Quality† in both dataset (Red-wine Quality, White-wine Quality) have a type †Å"Numeric†. So after applying this filter, class attribute â€Å"Quality† convert into type â€Å"Nominal†. * And Red-wine Quality dataset have class names 3, 4, 5 †¦ 8 and White-wine Quality dataset have class names 3, 4, 5 †¦ 9. * Because of classification does not apply on numeric type class field, there is a need for this filter. * InterquartileRange Filter (weka. filters. unsupervised. attribute. InterquartileRange) A filter for detecting outliers and extreme values based on interquartile ranges. The filter skips the class attribute. * Apply this filter for all attribute indices with all default options. * After applying, filter adds two more fields which names are â€Å"Outliers† and â€Å"ExtremeValue†. And this fields has two types of label â€Å"No† and â€Å"Yes†. Here â€Å"Yes† label indicates, there are outliers and extreme values in dataset. * In our dataset, there are 83 extreme values and 125 outliers i n White-wine Quality dataset and 69 extreme values and 94 outliers in Red-wine Quality. * RemoveWithValues Filter (weka. filters. unsupervised. instance.RemoveWithValues) * Filters instances according to the value of an attribute. * This filter has two options which are â€Å"AttributeIndex† and â€Å"NominalIndices†. * AttributeIndex choose attribute to be use for selection and NominalIndices choose range of label indices to be use for selection on nominal attribute. * In our dataset, AttributeIndex is â€Å"last† and NominalIndex is also â€Å"last†, so It will remove first 83 extreme values and then 125 outliers in White-wine Quality dataset and 69 extreme values and 94 outliers in Red-wine Quality. * After applying this filter on dataset remove both fields from dataset. * Attribute SelectionRanking Attributes Using Attribute Selection Algorithm| RED-WINE| RANKED| WHITE-WINE| Volatile_Acidity(2)| 0. 1248| 0. 0406| Volatile_Acidity(2)| Total_sulfer_Diox ide(7)| 0. 0695| 0. 0600| Citric_Acidity(3)| Sulphates(10)| 0. 1464| 0. 0740| Chlorides(5)| Alcohal(11)| 0. 2395| 0. 0462| Free_Sulfer_Dioxide(6)| | | 0. 1146| Density(8)| | | 0. 2081| Alcohal(11)| * The selection of attributes is performed automatically by WEKA using Info Gain Attribute Eval method. * The method evaluates the worth of an attribute by measuring the information gain with respect to the class. 5. STATISTICS USED IN ALGORITHMS * Statistics MeasuresThere are Different algorithms that can be used while performing data mining on the different dataset using weka, some of them are describe below with the different statistics measures. * Statistics Used In Algorithms * Kappa statistic * The kappa statistic, also called the kappa coefficient, is a performance criterion or index which compares the agreement from the model with that which could occur merely by chance. * Kappa is a measure of agreement normalized for chance agreement. * Kappa statistic describe that our predicti on for class attribute for given dataset is how much near to actual values. * Values Range For Kappa Range| Result| lt;0| POOR| 0-0. 20| SLIGHT| 0. 21-0. 40| FAIR| 0. 41-0. 60| MODERATE| 0. 61-0. 80| SUBSTANTIAL| 0. 81-1. 0| ALMOST PERFECT| * As above range in weka algorithm evaluation if value of kappa is near to 1 then our predicted values are accurate to actual values so, applied algorithm is accurate.

Another measure of how well the curve fits the data is Root Mean Squared Error. * For each data point, CalGraph calculates the value of  Ã‚  y from the formula. It subtracts this from the data's y-value and squares the difference. All these squares are added up and the sum is divided by the number of data. * Finally CalGraph takes the square root.

More specifically, this simple predictor is just the average of the actual values. Thus, the relative squared error takes the to tal squared error and normalizes it by dividing by the total squared error of the simple predictor. * By taking the square root of therelative squared error  one reduces the error to the same dimensions as the quantity being predicted. * Mathematically, the  root relative squared error  Ei  of an individual program  i  is evaluated by the equation: * where  P(ij)  is the value predicted by the individual program  i  for sample case  j  (out of  n  sample cases);  Tj  is the target value for sample case  j; andis given by the formula: * For a perfect fit, the numerator is equal to 0 and  Ei  = 0.So, the  Ei  index ranges from 0 to infinity, with 0 corresponding to the ideal.

In this case, though, the error is just the total absolute error instead of the total squared error. Thus, the relative absolute error takes the total absolute error and normalizes it by dividing by the total absolute error of the simple predictor. Mathematically, the  relative absolute error  Ei  of an individual program  i  is evaluated by the equation: * where  P(ij)  is the value predicted by the individual program  i  for sample case  j  (out of  n  sample cases);  Tj  is the target value for sample case  j; andis given by the formula: * For a perfect fit, the numerator is equal to 0 and  Ei  = 0.

And  false negative  (FN) is when the prediction outcome is  n while the actual value is  p. * Absolute Value | P| N| TOTAL| p’| True positive| false positive| P’| n’| false negative| True negative| N’| Total| P| N| | * ROC Curves * While estimating the effectiveness and accuracy of data mining technique it is essential to measure the error rate of each method. * In the case of binary classification tasks the error rate takes and components under consideration. * The ROC analysis which stands for Receiver Operating Characteristics is applied. * The sample ROC curve is presented in the Figure below.The closer the ROC curve is to the top left corner of the ROC chart the better the performance of the classifier. * Sample ROC curve (squares with the usage of the model, triangles without). The line connecting the square with triage is the benefit from the usage of the model. * It plots the curve which consists of x-axis presenting false positive rate and y-axis which plots the true positive rate. This curve model selects the optimal model on the basis of assumed class distribution. * The ROC curves are applicable e. g. in decision tree models or rule sets. * Recall, Precision and F-Measure There are four possible results of classification. * Different combination of these four error and correct situations are presented in the scientific literature on topic. * Here three popular notions are presented. The introduction of the se classifiers is explained by the possibility of high accuracy by negative type of data. * To avoid such situation recall and precision of the classification are introduced. * The F measure is the harmonic mean of precision and recall. * The formal definitions of these measures are as follow : PRECSION = TPTP+FP RECALL = TPTP+FNF-Measure = 21PRECSION+1RECALL * These measures are introduced especially in information retrieval application. * Confusion Matrix * A matrix used to summarize the results of a supervised classification. * Entries along the main diagonal are correct classifications. * Entries other than those on the main diagonal are classification errors. 6. ALGORITHMS * K-Nearest Neighbor Classifiers * Nearest neighbor classifiers are based on learning by analogy. * The training samples are described by n-dimensional numeric attributes. Each sample represents a point in an n-dimensional space. In this way, all of the training samples are stored in an n-dimensional pattern space. When given an unknown sample, a k-nearest neighbor classifier searches the pattern space for the k training samples that are closest to the unknown sample. * These k training samples are the k-nearest neighbors of the unknown sample. â€Å"Closeness† is defined in terms of Euclidean distance, where the Euclidean distance between two points, , * The unknown sample is assigned the most common class among its k nearest neighbors. When k = 1, the unknown sample is assigned the class of the training sample that is closest to it in pattern space. Nearest neighbor classifiers are instance-based or lazy learners in that they store all of the training samples and do not build a classifier until a new (unlabeled) sample needs to be classified. * Lazy learners can incur expensive computational costs when the number of potential neighbors (i. e. , stored training samples) with which to compare a given unlabeled sample is great. * Therefore, they require efficient indexing techniqu es. As expected, lazy learning methods are faster at training than eager methods, but slower at classification since all computation is delayed to that time.Unlike decision tree induction and back propagation, nearest neighbor classifiers assign equal weight to each attribute. This may cause confusion when there are many irrelevant attributes in the data. * Nearest neighbor classifiers can also be used for prediction, i. e. to return a real-valued prediction for a given unknown sample. In this case, the classifier returns the average value of the real-valued labels associated with the k nearest neighbors of the unknown sample. * In weka the previously described algorithm nearest neighbor is given as Kstar algorithm in classifier -> lazy tab.

A decision tree is a predictive machine-learning model that decides the target value (dependent variable) of a new sample based on various attribute values of the available data. * The internal nodes of a decision tree denote the different attribute; the branches between the nodes tell us the possible values that these attributes can have in the observed samples, while the terminal nodes tell us the final value (class ification) of the dependent variable. * The attribute that is to be predicted is known as the dependent variable, since its value depends upon, or is decided by, the values of all the other attributes.The other attributes, which help in predicting the value of the dependent variable, are known as the independent variables in the dataset. * The J48 Decision tree classifier follows the following simple algorithm: * In order to classify a new item, it first needs to create a decision tree based on the attribute values of the available training data. So, whenever it encounters a set of items (training set) it identifies the attribute that discriminates the various instances most clearly. * This feature that is able to tell us most about the data instances so that we can classify them the best is said to have the highest information gain. Now, among the possible values of this feature, if there is any value for which there is no ambiguity, that is, for which the data instances falling wi thin its category have the same value for the target variable, then we terminate that branch and assign to it the target value that we have obtained. * For the other cases, we then look for another attribute that gives us the highest information gain. Hence we continue in this manner until we either get a clear decision of what combination of attributes gives us a particular target value, or we run out of attributes.In the event that we run out of attributes, or if we cannot get an unambiguous result from the available information, we assign this branch a target value that the majority of the items under this branch possess. * Now that we have the decision tree, we follow the order of attribute selection as we have obtained for the tree. By checking all the respective attributes and their values with those seen in the decision tree model, we can assign or predict the target value of this new instance. * The Result Generated After Applying J48 On White-wine Quality Dataset Time Taken To Build Model: 1. 4 Seconds| Stratified Cross-Validation (10-Fold) | * Summary| | | Correctly Classified Instances| 2740 | 58. 547 %| Incorrectly Classified Instances | 1940 | 41. 453 %| Kappa Statistic | 0. 3813| | Mean Absolute Error | 0. 1245| | Root Mean Squared Error | 0. 3194| | Relative Absolute Error | 64. 5770 %| | Root Relative Squared Error| 102. 9013 %| | Total Number Of Instances | 4680| | * Detailed Accuracy By Class| | TP Rate| FP Rate| Precision| Recall| F-Measure| ROC Area| Class| | 0| 0. 002| 0| 0| 0| 0. 30| 3| | 0. 239| 0. 020| 0. 270| 0. 239| 0. 254| 0. 699| 4| | 0. 605| 0. 169| 0. 597| 0. 605| 0. 601| 0. 763| 5| | 0. 644| 0. 312| 0. 628| 0. 644| 0. 636| 0. 689| 6| | 0. 526| 0. 099| 0. 549| 0. 526| 0. 537| 0. 766| 7| | 0. 363| 0. 022| 0. 388| 0. 363| 0. 375| 0. 75| 8| | 0| 0| 0| 0| 0| 0. 496| 9| Weighted Avg. | 0. 585 | 0. 21 | 0. 582 | 0. 585 | 0. 584 | 0. 727| | * Confusion Matrix | A| B| C| D| E| F| G| || Class| 0| 2| 6| 5| 0| 0| 0| || A=3| 1| 34| 55| 44| 6| 2| 0| || B=4| 5| 50| 828| 418| 60| 7| 0| || C=5| 2| 32| 413| 1357| 261| 43| 0| || D=6| | 7| 76| 286| 459| 44| 0| || E=7| 1| 1| 10| 49| 48| 62| 0| || F=8| 0| 0| 0| 1| 2| 2| 0| || G=9| * Performance Of The J48 With Respect To A Testing Configuration For The White-wine Quality Dataset Testing Method| Training Set| Testing Set| 10-Fold Cross Validation| 66% Split| Correctly Classified Instances| 90. 1923 %| 70 %| 58. 547 %| 54. 8083 %| Kappa statistic| 0. 854| 0. 6296| 0. 3813| 0. 33| Mean Absolute Error| 0. 0426| 0. 0961| 0. 1245| 0. 1347| Root Mean Squared Error| 0. 1429| 0. 2756| 0. 3194| 0. 3397| Relative Absolute Error| 22. 0695 %| | 64. 577 %| 69. 84 %| * The Result Generated After Applying J48 On Red-wine Quality Dataset Time Taken To Build Model: 0. 17 Seconds| Stratified Cross-Validation| * Summary| Correctly Classified Instances | 867 | 60. 7994 %| Incorrectly Classified Instances | 559 | 39. 2006 %| Kappa Statistic | 0. 3881| | Mean Absolute Error | 0. 1401| | Root Mean Squa red Error | 0. 3354| | Relative Absolute Error | 65. 4857 %| | Root Relative Squared Error | 102. 602 %| |Total Number Of Instances | 1426 | | * Detailed Accuracy By Class| | Tp Rate | Fp Rate | Precision | Recall | F-measure | Roc Area | Class| | 0 | 0. 004 | 0 | 0 | 0 | 0. 573 | 3| | 0. 063 | 0. 037 | 0. 056 | 0. 063 | 0. 059 | 0. 578 | 4| | 0. 721 | 0. 258 | 0. 672 | 0. 721 | 0. 696 | 0. 749 | 5| | 0. 57 | 0. 238 | 0. 62 | 0. 57 | 0. 594 | 0. 674 | 6| | 0. 563 | 0. 64 | 0. 553 | 0. 563 | 0. 558 | 0. 8 | 7| | 0. 063 | 0. 006 | 0. 1 | 0. 063 | 0. 077 | 0. 691 | 8| Weighted Avg. | 0. 608 | 0. 214 | 0. 606 | 0. 608 | 0. 606 | 0. 718 | | * Confusion Matrix | A | B | C | D | E | F | | Class| 0 | 2 | 1 | 2 | 1 | 0 | | | A=3| 2 | 3 | 25 | 15 | 3 | 0 | | | B=4| 1 | 26 | 435 | 122 | 17 | 2 | | | C=5| 2 | 21 | 167 | 329 | 53 | 5 | | | D=6| 0 | 2 | 16 | 57 | 99 | 2 | | | E=7| 0 | 0 | 3 | 6 | 6 | 1 | | | F=8| Performance Of The J48 With Respect To A Testing Configuration For The Red-wine Qual ity Dataset Testing Method| Training Set| Testing Set| 10-Fold Cross Validation| 66% Split| Correctly Classified Instances| 91. 1641 %| 80 %| 60. 7994 %| 62. 4742 %| Kappa statistic| 0. 8616| 0. 6875| 0. 3881| 0. 3994| Mean Absolute Error| 0. 0461| 0. 0942| 0. 1401| 0. 1323| Root Mean Squared Error| 0. 1518| 0. 2618| 0. 3354| 0. 3262| Relative Absolute Error| 21. 5362 %| 39. 3598 %| 65. 4857 %| 62. 052 %| * Multilayer Perceptron * The back propagation algorithm performs learning on a multilayer feed-forward neural network. It iteratively learns a set of weights for prediction of the class label of tuples. * A multilayer feed-forward neural network consists of an input layer, one or more hidden layers, and an output layer. * Each layer is made up of units. The inputs to the network correspond to the attributes measured for each training tuple. The inputs are fed simultaneously into the units making up the input layer. These inputs pass through the input layer and are then weighted an d fed simultaneously to a second layer of â€Å"neuronlike† units, known as a hidden layer. The outputs of the hidden layer units can be input to another hidden layer, and so on. The number of hidden layers is arbitrary, although in practice, usually only one is used. The weighted outputs of the last hidden layer are input to units making up the output layer, which emits the network’s prediction for given tuples. * The units in the input layer are called input units. The units in the hidden layers and output layer are sometimes referred to as neurodes, due to their symbolic biological basis, or as output units. * The network is feed-forward in that none of the weights cycles back to an input unit or to an output unit of a previous layer.It is fully connected in that each unit provides input to each unit in the next forward layer. * The Result Generated After Applying Multilayer Perceptron On White-wine Quality Dataset Time taken to build model: 36. 22 seconds| Stratifi ed cross-validation| * Summary| Correctly Classified Instances | 2598 | 55. 5128 %| Incorrectly Classified Instances | 2082 | 44. 4872 %| Kappa statistic | 0. 2946| | Mean absolute error | 0. 1581| | Root mean squared error | 0. 2887| |Relative absolute error | 81. 9951 %| | Root relative squared error | 93. 0018 %| | Total Number of Instances | 4680 | | * Detailed Accuracy By Class | | TP Rate | FP Rate | Precision | Recall | F-Measure | ROC Area | PRC Area | Class| | 0 | 0 | 0 | 0 | 0 | 0. 344 | 0. 002 | 3| | 0. 056 | 0. 004 | 0. 308 | 0. 056 | 0. 095 | 0. 732 | 0. 156 | 4| | 0. 594 | 0. 165 | 0. 597 | 0. 594 | 0. 595 | 0. 98 | 0. 584 | 5| | 0. 704 | 0. 482 | 0. 545 | 0. 704 | 0. 614 | 0. 647 | 0. 568 | 6| | 0. 326 | 0. 07 | 0. 517 | 0. 326 | 0. 4 | 0. 808 | 0. 474 | 7| | 0. 058 | 0. 002 | 0. 5 | 0. 058 | 0. 105 | 0. 8 | 0. 169 | 8| | 0 | 0 | 0| 0 | 0 | 0. 356 | 0. 001 | 9| Weighted Avg. | 0. 555 | 0. 279 | 0. 544 | 0. 555 | 0. 532 | 0. 728 | 0. 526| | * Confusion Matrix |A | B | C | D | E | F | G | | Class| 0 | 0 | 5 | 7 | 1 | 0 | 0 | | | A=3| 0 | 8 | 82 | 50 | 2 | 0 | 0 | | | B=4| 0 | 11 | 812 | 532 | 12 | 1 | 0 | | | C=5| 0 | 6 | 425 | 1483 | 188 | 6 | 0 | | | D=6| 0 | 1 | 33 | 551 | 285 | 3 | 0 | | | E=7| 0 | 0 | 3 | 98 | 60 | 10 | 0 | | | F=8| 0 | 0 | 0 | 2 | 3 | 0 | 0 | | | G=9| * Performance Of The Multilayer perceptron With Respect To A Testing Configuration For The White-wine Quality DatasetTesting Method| Training Set| Testing Set| 10-Fold Cross Validation| 66% Split| Correctly Classified Instances| 58. 1838 %| 50 %| 55. 5128 %| 51. 3514 %| Kappa statistic| 0. 3701| 0. 3671| 0. 2946| 0. 2454| Mean Absolute Error| 0. 1529| 0. 1746| 0. 1581| 0. 1628| Root Mean Squared Error| 0. 2808| 0. 3256| 0. 2887| 02972| Relative Absolute Error| 79. 2713 %| | 81. 9951 %| 84. 1402 %| * The Result Generated After Applying Multilayer Perceptron On Red-wine Quality Dataset Time taken to build model: 9. 14 seconds| Stratified cross-validation (10-Fold)| * Summary | Co rrectly Classified Instances | 880 | 61. 111 %| Incorrectly Classified Instances | 546 | 38. 2889 %| Kappa statistic | 0. 3784| | Mean absolute error | 0. 1576| | Root mean squared error | 0. 3023| | Relative absolute error | 73. 6593 %| | Root relative squared error | 92. 4895 %| | Total Number of Instances | 1426| | * Detailed Accuracy By Class | | TP Rate | FP Rate | Precision | Recall | F-Measure | ROC Area | Class| | 0 | 0 | 0 | 0 | 0 | 0. 47 | 3| | 0. 42 | 0. 005 | 0. 222 | 0. 042 | 0. 070 | 0. 735 | 4| | 0. 723 | 0. 249 | 0. 680 | 0. 723 | 0. 701 | 0. 801 | 5| | 0. 640 | 0. 322 | 0. 575 | 0. 640 | 0. 605 | 0. 692 | 6| | 0. 415 | 0. 049 | 0. 545 | 0. 415 | 0. 471 | 0. 831 | 7| | 0 | 0 | 0 | 0 | 0 | 0. 853 | 8| Weighted Avg. | 0. 617 | 0. 242 | 0. 595 | 0. 617 | 0. 602 | 0. 758| | * Confusion Matrix | A | B | C | D | E | F | | Class| | 0 | 5 | 1 | 0 | 0| || A=3| 0 | 2 | 34 | 11 | 1 | 0 | | | B=4| 0 | 2 | 436 | 160 | 5 | 0 | | | C=5| 0 | 5 | 156 | 369 | 47 | 0 | | | D=6| 0 | 0 | 10 | 93 | 73 | 0 | | | E=7| 0 | 0 | 0 | 8 | 8 | 0 | | | F=8| * Performance Of The Multilayer perceptron With Respect To A Testing Configuration For The Red-wine Quality Dataset Testing Method| Training Set| Testing Set| 10-Fold Cross Validation| 66% Split| Correctly Classified Instances| 68. 7237 %| 70 %| 61. 7111 %| 58. 7629 %| Kappa statistic| 0. 4895| 0. 5588| 0. 3784| 0. 327| Mean Absolute Error| 0. 426| 0. 1232| 0. 1576| 0. 1647| Root Mean Squared Error| 0. 2715| 0. 2424| 0. 3023| 0. 3029| Relative Absolute Error| 66. 6774 %| 51. 4904 %| 73. 6593 %| 77. 2484 %| * Result * The classification experiment is measured by accuracy percentage of classifying the instances correctly into its class according to quality attributes ranges between 0 (very bad) and 10 (excellent). * From the experiments, we found that classification for red wine quality using  Kstar algorithm achieved 71. 0379 % accuracy while J48 classifier achieved about 60. 7994% and Multilayer Perceptron classifier ac hieved 61. 7111% accuracy. For the white wine, Kstar algorithm yielded 70. 6624 % accuracy while J48 classifier yielded 58. 547% accuracy and Multilayer Perceptron classifier achieved 55. 5128 % accuracy. * Results from the experiments lead us to conclude that Kstar performs better in classification task as compared against the J48 and Multilayer Perceptron classifier. The processing time for Kstar algorithm is also observed to be more efficient and less time consuming despite the large size of wine properties dataset. 7.

Step3: Now take any 10 or 15 records from your dataset, make their class value unknown(by putting ’? ’ in the cell of the corresponding raw ) as shown below. Step 4: Save this data set as . rff file. Step 5: From â€Å"tes t option† panel select â€Å"supplied test set†, click on to the set button and open the test dataset file which was lastly created by you from the disk. Step 6: From â€Å"Result list panel† panel select Kstar-algorithm (because it is better than any other for this dataset), right click it and click â€Å"Re-evaluate model on current test set† Step 7: Again right click on Kstar algorithm and select â€Å"visualize classifier error† Step 8:Click on save button and then save your test model.Step 9: After you had saved your test model, a separate file is created in which you will be having your predicted values for your testing dataset. Step 10: Now, this test model will have all the class value generated by model by re-evaluating model on the test data for all the instances that were set to unknown, as shown in the figure below. 9. ACHIEVEMENT * Classification models may be used as part of decision support system in different stages of wine productio n, hence giving the opportunity for manufacturer to make corrective and additive measure that will result in higher quality wine being produced. From the resulting classification accuracy, we found that accuracy rate for the white wine is influenced by a higher number of physicochemistry attribute, which are alcohol, density, free sulfur dioxide, chlorides, citric acid, and volatile acidity. * Red wine quality is highly correlated to only four attributes, which are alcohol, sulphates, total sulfur dioxide, and volatile acidity. * This shows white wine quality is affected by physicochemistry attributes that does not affect the red wine in general. Therefore, I suggest that white wine manufacturer should conduct wider range of test particularly towards density and chloride content since white wine quality is affected by such substances. * Attribute selection algorithm we conducted also ranked alcohol as the highest in both datasets, hence the alcohol level is the main attribute that d etermines the quality in both red and white wine. * My suggestion is that wine manufacturer to focus in maintaining a suitable alcohol content, may be by longer fermentation period or higher yield fermenting yeast.
