Counterinsurgency in Iraq

Since the start of the Iraq insurgency in 2003 before the ruling of a new supreme government within its borders, the armed resistance of Iraqi security forces, insurgents and militia bursted, as Iraqi rebels instigated an ‘asymmetric war’ with much foreign assistance coming from NGOs and countries like Iran. Instead of attacking only the coalition forces and the acting government, insurgents started to attack even the less significant supporters.This paper suggests that the counterinsurgency in Iraq had been presenting immense risks and destruction to all parties, but especially to the U. S. , which had something to do with demography, economy, and power. By evaluating the event using the three basic criteria, it shall be concluded why counterinsurgency in Iraq should be brought to a halt. As social chaos and economic constraints have not been treated very well, the act of counterinsurgency has only made matters worse, as it brings destruction even to the United States o f America. Main Body Criterion #1: demography-related ruin In terms of demography, counterinsurgency in Iraq had only made matters worse since 2003.In the Information Clearing House article written by Linda Bilmes and Joseph Stiglitz entitled ‘The Economics Costs of the Iraq War: An Appraisal Three Years after the Beginning of the Conflict’, it is said that there were approximately 2,000 American combatants who had died from March 2003 to January 2006, and about 16,000 American combatants who had been wounded during those same years (2006, p. 2). However, as of now, the number of deaths went up from 2,000 to 4,147 in totality (Casualties in Iraq, 2008); while the number of wounded went up from 16,000 in early 2006 to exactly 30,561 in totality as of now (Casualties in Iraq, 2008).As of early 2006, this number of deaths led to benefits and insurances that totals a staggering $100,000 death benefits and as much as $500,000 life insurances (Bilmes & Stiglitz, 2006, p. 2). These numbers project the conclusion that demography-related ruin of the United States in the Iraq War damages not just the lives but also the economy of the nation. It can be evaluated that, in terms of demography, destruction brought by the Iraq War projects staggering amount and, thus, a disparaging situation. Criterion #2: economy-related ruinSecondly, in terms of economy, counterinsurgency in Iraq had only made matters worse since 2003. In the newspaper article also written by Linda Bilmes and Joseph Stiglitz entitled ‘The Iraq War Will Cost Us $3 Trillion, and Much More’, it was said that failed war at this age costs $3 trillion and that the costs and damages of the Iraq War has surpassed the financial costs of the World War II (2008, p. B01). As it was written, â€Å"As we approach the fifth anniversary of the invasion, Iraq is not only the second longest war in U. S.history (after Vietnam), it is also the second most costly—surpassed only by World War II † (Bilmes & Stiglitz, 2008, p. B01). With a ‘conservative’ estimate of about $12 billion expenses per month (or $16 billion if the one in Afghanistan would be included), the Iraq War depletes America’s resources that should have been allotted to other expenses at this present age. These numbers project the conclusion that economy-related ruin of the United States in the Iraq War damages not just the economy but also the future of the nation.It can be evaluated that, in terms of economy, destruction brought by the Iraq War projects staggering amount and, thus, a similarly disparaging situation. Criterion #3: power-related ruin Lastly, in terms of power, counterinsurgency in Iraq had only made matters worse since 2003. Together with the demographic and economic ruin, national power is being depleted because of the fact that â€Å"population [is] one of the most important indicators of national power because of its importance for determining economic and mili tary power† (Yoshihara, 2008, p.2). According to Susan Yoshihara (2008), Hans Morgenthau has pointed out the eight means of power appear to be the following: (1) geography, (2) natural resources, (3) industrial capacity, (4) military preparedness, (5) population, (6) national character, (7) national morale, and (8) quality of government (p. 3). Therefore, because the Iraq War is destruction to both demography and economy, the third, fourth and fifth means of power that are industrial capacity, military preparedness, and population are also being negatively affected by the war.Destruction to these three means of power implies destruction of power. This projects that demography-related and economy-related ruin of the United States in the Iraq War means power-related ruin. Thus, it can be evaluated that, in terms of power, the Iraq War projects destructive elements that lead to a similarly disparaging situation. Conclusion From the stated paragraphs, it appears that the counterin surgency in Iraq had been presenting immense risks and destruction to all parties, even to the American population.In relation to the three criteria that is demography, economy, and power, we can evaluate that counterinsurgency in Iraq should be brought to a halt. The war had only succeeded in bringing the country more than 4,000 deaths, more than 30,000 wounded, about $3 trillion worth of financial costs, with depleting power and less economic resources. It only brought social chaos and economic constraints. We should bring it to an end. Counterinsurgency can be defined as â€Å"military and political activities undertaken by a government to defeat a rebellion or guerrilla movement† (Counterinsurgency, 2008).As the United States started to invade and occupy Iraq in 2003 (Pirnie & O’Connell, 2008, p. xiii), it is evident that counterinsurgency had been quite tough, as numerous armed groups were united with a common theme that â€Å"[t]he occupation of Iraq by foreign forces is bad† (Pirnie & O’Connell, 2008, p. xiii). Yet, the case appeared to be a lot worse than just plain revolt. References Bilmes, L. , & Stiglitz, J. E. (2006, January).

What is Post-Modernism, functionalism and Marxism?

What is Post-Modernism, functionalism & Marxism? What is ‘The Matrix'? And what have these three got to do with ‘The Matrix'? These questions are very difficult to answer some would say and others wouldn't have much of a problem. Firstly, Post-Modernism, some claim, is replacing modernity. It's being done by the loss of faith in science and rationality. These types of thoughts developed mainly from the 1980's onwards and increased sceptism about theories of a better future. However these thoughts are in a relativist position, which denies that there are absolutes in any area of human knowledge. People believe that social positions of the informer are informed. Secondly, Functionalism means â€Å"structures, which fulfil the objective to maintain a system†. This basically means functionalists try and maintain order and peace in society. Lastly there's Marxism. This is totally the opposite to a functionalist perspective. Marxism tries to create conflict between people and it always picks up on the negative views within society or organisations. You're probably thinking what has all this got to do with ‘The Matrix'? Well, ‘The Matrix' as we all know was one of the biggest hit films in America and the UK. It is all about the future and what the world is really like. How it's seen through selected individual's eyes. Keanu Reeves stars as ‘Neo' in the movie, and ‘Neo' means the one in a foreign language. The Matrix is known as a system, a computer. The Matrix basically being the Planet Earth. At the start of the movie ‘Neo' is an ‘everyday' individual, working with computers for his living until he begins to receive eerie messages on his PC and peculiar phone calls. This shows a functionalist and working class perspective as he's an ordinary guy and lives a normal life earning money for his living. After this Neo is given an instruction which said to ‘Follow the sign'. The sign being a white rabbit on a females shoulder. Here we can see that this is completely un-natural, who hacks into computers and telephone lines to show a dull message? At first he was totally against going further with the matter but then he didn't no what to do. This shows a Post-Modernism type of view as he's undecided in what he wants to do. However ‘Neo' was very curious and he decided to follow the sign. This again shows a form of Post-Modernism as he wants to know what's behind all these ‘Signs'. Having followed the white rabbit he's led to a club where he meets a lady called Trinity who begins to show Neo things he's never seen before. After all this Neo wakes up in his bedroom, as if nothing has happened but he still remembers everything. So this is a type of modern view, bringing Neo back to the ‘Truth' and ‘Reality' part of the universe. The following day he meets again with this lady named Trinity and she shows him ‘The One', Morpheus. Morpheus is the leader of the group at present. Neo is taken into a room where he is given two options, one where he has the option to take a red pill or the other where he takes a blue pill. The red pill keeps Neo in the ‘fantasy' land and the blue which takes him back to his normal life where he forgets everything. Neo decides to take a really big chance and stay in the land of fantasy and takes the red pill. This shows a major type of Post-modernism, wanting to know more, wanting to know about other realms, and basically being really curious. It also shows a modern view as it didn't take much time for him to decide what he wanted to do. Having taken this pill Neo is ‘Re-Born' in a totally different way and is picked up by this strange looking creature and is thrown down this shoot to the other crew members. A number of people would definitely say this is creating a Jesus like sense; being ‘Re-Born' and again this could cause conflict between some groups. So Neo decided to leave his ‘modern' style life and live in another ‘Realm'. A few tests are run on Neo and he is given the all clear through Morpheus. Neo meets all his other crew members, some of their names being Tank, A-Poc and Switch. After this Neo is taken to a computer program where he battles with his leader Morpheus, Neo begins to realise he can do things he had never done before, such as fighting Kung-Fu style. Some may argue that this is a type of conflict or Marxism as he is being taught how to fight. Neo is also taken into a computer program where he is told to jump between two buildings which a really high and really far apart. Morpheus shows him how to do it, Neo tries to believe he can do and jumps. However he was unsuccessful, so this is trying to make Neo believe something he cannot do at the moment. So he fails the jump but is still alive as it was only a computer program. Neo begins to believe even more. Neo is taken back to the crew where he sleeps. Later on Neo is taken on a mission with his crew into ‘The Matrix' where they are attacked by ‘Agents', these are people who are against Morpheus and would take any measure to kill any one of them. In a way this shows reality because there are some people out there who are willing to kill an individual at any expense. The group could be a Marxist group because all they want to do is create conflict between each other. Again some can argue that Neo's group are doing the same. Neo and the rest manage to escape excluding Morpheus, who is beaten and taken away with the Agents. Again this is a Marxist perspective as the agents are trying to create conflict. The only way of exiting ‘The Matrix' is by receiving a phone call on selected telephones. These phones take them back to the ‘Real World'. This is a post modernist point of view as this wouldn't normally happen in the world as we know it. Tank manages to get back safely and decides to cause a big problem. He agreed with the ‘Agents' that he would do anything to get out of the ‘Real world' and return to ‘The Matrix'. This is definitely a Marxist view, as he is trying to create conflict whereas the other crew members are trying to create some form of order in the ‘Real World' while they battle it out with tank. Unfortunately for tank he is defeated and the rest manage to get back safely. They all begin to panic about Morpheus because they know that if anyone dies in ‘The Matrix' dies in the ‘Real World'. Neo decides its time for him to shine and takes the matter into his own hands. This again can be seen as a functionalist perspective as he wants to create order but in order to do this he is going to create conflict. He returns to ‘The Matrix' along with Trinity and seeks out Morpheus. The two groups battle it out and finally they reach a result. Neo defeats the ‘Agents' and realises he had powers which he never knew he had. However, Morpheus dies and Neo takes over the role of being ‘The One'. Overall we can see that there are functionalist, Marxist and Post-Modern perspectives throughout the whole of the film. Some for good, some for bad, but which are which is for you to decide. At times it's about your own personal views or opinions.

Education and Auditory Work Hand

My learning style involves all three visual, auditory, and tactile. Using combinations of all three of these learning styles increases my chances of learning and remembering. I find that reading and studying before a test helps me a lot, as well as taking notes and listening to my teachers during class's. It is also every important to me to reduce stress before I learn. Being a visual learner I learn by reading questions and answers, watching demonstrations and presentations. I find that underlining in a different color test information I am ble to retain more information visually, also using tools improves the ability to recall more information complete. I can benefit from being an auditory learner by watching videos and participating in group discussions, using word association to remember facts and lines. I also sometimes need to hear information and read out loud to learn, it is sometimes easier for me to listen to somebody talk then for me to read it myself. Also being a tactile learner i find that sometimes it is easier to learn by drawing pictures nd brainstorming using mind maps, it helps to study with others and take field trips. Hands on experience is a good way of learning and remembering. Visual and auditory work hand in hand, you can hear something and with a picture or a diagram you can also see it, giving you a better chance of understanding it. Being visual and tactile watching someone else do it and explaining it such as a teacher is also very effective. Using auditory and tactile hands on experience has always helped me, if I have done it once with y hands, talked about it I will be able to do it again. So when learning I find it easier to use more than just one style at a time. In combination any two styles make it more understandable and easier to remember. When learning and all three styles are used I have the best chance for remembering it because if I can recall one of the things such as what a teacher said or what a teacher was doing, or what I was doing I should be able to remember the rest of the answers to the questions.

Consumerism and Identity Essay Example | Topics and Well Written Essays - 1000 words - 10

Consumerism and Identity - Essay Example In this paper I will qualify the statement that the capitalist commercial culture has been blamed for the bad experiences in the society. Argument for the Claim The society has continually faced problems that range from economic to political, and fingers point to the commercial culture of capitalism. Profit motive in the commercial sector plays an important role on food that people eat and to a great extent account for effects of other consumables. Emergence of economic concepts of cost minimization towards optimal profits play a core role as capitalists seeks less costly strategies to productions and marketing strategies for market control. In the food industry, for example, industrialization has transformed eating habits to commercially processed foods that are rich in chemicals and fats and expose consumers to eating disorders such as overweight. Using the media to penetrate into new markets also influences consumers towards the capitalists’ products and increases incidence s of effects of industrial products (Twitchell 1). Economic effects of capitalism also support the claim that the commercial culture is responsible for depression and associated disorders among members of the society. Unlike in socialist culture where the society owns resources and collectivism ensures needs of every member of the society, capitalism concentrates excessive resources on a few individuals while a majority of members of the society remain in poverty and have to struggle for their needs. Human suffering due to lack of basic needs or wants therefore flourish in the society while a non-capitalist system would have resolved such conditions. The condition worsens by capitalists’ selfish interest that seeks to increase the capitalists’ possession at the expense of the working class that mainly lives in poverty. Capitalist commercial culture has also threatened social cultures and cultural figures through undermining cultural values. Competitiveness in the corpo rate sector and the profit orientation of capitalists has for example promoted creativity into cultural shifts in what appears as better practices and utilities. Cultures and their benefits to the society have suffered from the developments as they become inferior and lose value. High level of competition in the market and self-interest has also promoted ills such as corruption and associated consequences in substandard products that risk consumers’ lives and undermine economic growth (Twitchell 1). Established criticisms of the commercial culture also support Twitchell’s position that the culture does not benefit the society. Some oppressive conditions are manageable, especially through collective responsibility as observed in socialist culture, but self-centered interest in the capitalist culture overlooks strategies for resolving the conditions. Widening gap between economic classes is an example and explains why the poor get poorer and the rich continue to amass we alth. Capitalistic culture also undermines efforts for harmonizing living standards in the economy and promotes such acts as discrimination and exploitation to promote suffering and stress.

Case study assignment - Essay Example The Tokyo management concept could not be successful because the French population was not as open to the American ideas as was the Japanese audiences, very exited to see the American Disneyland experience no matter what it cost. Financial losses compelled management to charge high rates of rooms rent and food served. The management found flaws in the European perspective of market financing while comparing it with the US market financing. Later, management revised the marketing plan for Disney by implementing strategic and tactic changes at the right time. Changes were made to adapt to the French culture by allowing wine andentry of pets in the Disneyland. The French characters like Zorro, Mary Poppins, and Alladin were casted in advertisements along with celebration of Donald Duck’s birthday to position EuroDisney on the top of the European destinations for short time visits. The new French CEO changed marketing tactics by capturing local markets based on different touristsà ¢â‚¬â„¢ habits. Advertisements and packages were structured according to the city marketing trends. Park admission rates were reduced by 20% and room rents by 30% with special promotions for the winter season. The name of the park was changed to Disneyland Paris (Case Study). Taking a lesson from its experiences of Tokyo Disney management, the Hong Kong Disneyland marketing strategy was made keeping mainly the Asian audiences in view. Local cultural traditions were particularly taken care not to antagonize the feelings of public as it happened in the case of Tokyo Disneyland. The American experience matched only in the matter of admission fee, which was marginally more affordable and similar to the Disney’s US parks in California and Florida than to the fees in Tokyo and Paris (Asia Times 2005). According to Roy Tan Hardy, vice president of marketing and sales of Hong Kong Disneyland, regarding park’s attractions â€Å"We carried out extensive, in-depth consumer insight

The impact of the Land Registration Act 2002 on the conveyancing Essay

The impact of the Land Registration Act 2002 on the conveyancing process in registered land - Essay Example It served well for nearly 80 years and was able to cope with the fundamental economic and social changes that took place over that time. Today, nearly all land is ‘registered land’ and the system underwent significant reform with the enactment of the Land Registration Act (LRA) 2002 that entered into force on 13 October 2003. The Land Registration Act 2002 has been received with much critical acclaim, and rightly so. It is a work of monumental importance and monumental effort. Law Commission Report No 271 was itself the last in a long series of Reports discussing, proposing, rejecting and recommending changes to the fundamentals of the land registration system established by the Land Registration Act 1925 . As is well known, the Act of 2002 is designed to revolutionize conveyancing in England and Wales and to bring the land registration system established by the 1925 Land Registration Act into the modern age. In fact LRA 2002 was primarily designed to facilitate e-convey ancing: that is the holding and transfer of estates and interests in land electronically. This goal of a virtually paper free conveyancing system has not yet been achieved because the e-conveyancing provisions of the LRA 2002 have not yet been triggered , but the structure of registered land under 2002 Act is designed to ensure that e-conveyancing will work when the remaining technological issues have been resolved.

Determining Causes and Effects Assignment Example | Topics and Well Written Essays - 1000 words

Determining Causes and Effects - Assignment Example This paper seeks to establish the major causes of stress and their subsequent effects on college students. In order to achieve this, the paper will categorize stress into a number of classes. These categories are broad representations of the underlying stress causing factors which will be subsequently broken down to give an insight on the stressors. The college environment is a dynamic mix of students from different cultural backgrounds and orientations. These students are meant to interact within the school environment. These interactions could be based on curricular or extra-curricular activities. The transitional approach to college life requires that the student adapt to the new college environment. Freshmen for instance are known to experience heightened levels of stress in trying to settle in to the new dimensions of college life. The students are required to learn interpersonal skills that will enable them cope with other students from diverse cultural backgrounds. Due to the diversity in culture orientations, conflicts are meant to arise. The occurrence of conflicts is commonplace in any society. The most important thing however is finding a way to resolve these conflicts. Unresolved conflicts that arise due to interpersonal interactions between students lead to substantial increase in stress levels (Wright, 1967). An individual is a complex assembly of different faculties, the body, and the soul. The individual ultimate end is achieving happiness. The intricate mix of the body and soul play an integral role in achieving this ultimate end. All the actions an individual engages in are meant to derive some form of satisfaction and happiness to the individual. In the event that the individual engages in activities that fail to realize this objective, then he/she is stressed. Intrapersonal factors refer to the mix of factors that shape the path that an

Chameleons Organism Physiology Essay Example for Free

Chameleons Organism Physiology Essay We know that an organism is anything that is living and can function by itself. This paper will help understand chameleons and how they have evolved to adapt to their surroundings. It will also discuss their physical features inside and out. Myths and facts will be revealed, as well as a few comparisons between sexes. Though there are many species of chameleons, everything discussed will be in reference to them as a whole. Chameleons are part of the reptile family. Half of their population lives and originated from Madagascar. Others can be found in the Middle East, Europe, and India. Fossils show that chameleons have been around for more than 26 million years (Klappenbach, 2014). The two scientific names given to them are Brookesiini and Chamaeleonini. Their known life span is to be around five to nine years (Switch Zoo , 2013). They are omnivores and carnivores, so their diet consists of insects, fruit, animals and flowers. There are also more than 135 different species of chameleons and six different subfamilies, which are Bradypodian, Brookesia, Calumma, Rhampolean, Chamaeleo, and Furcifer (Chameleons Online, 2002). The bulge underneath their tails can determine the sex of a chameleon visibly. This specie is commonly found in three types of habitats. The main one is the forest, where there are many trees and bushes for them to travel and hide. This is the same for scrublands, which is the second habitat. It is common for chameleons to want to stay off the ground and higher up, but few do like to make home in fallen leaves and sticks in large open areas. The third habitat is the desert, and even though it is hot and dry, few chameleons can still survive. Chameleons possess many features that are critical to their  survival, i (Komeleons). The first and well-known feature is their skin color. Their skin helps them to blend into their environment, but also stand out. They are able to regulate their body temperature and communicate based on the color of their skin. The important thing to know is that a chameleon’s skin color is a reflection of their feelings. When they feel threatened and s cared they will turn a dull color like a grey or a brown. When they feel dominant and want to defend themselves or their territory they will turn bright colors to seem more intimidating. There is evidence that suggests that chameleons evolved to stand out not to blend in. The reason their skin is able to change so many colors is because there is a layer of different pigments underneath known as chromatophore cells. There are four layers of skin cells that go in the order of yellow, red, blue, and brown in color. The color changing is from their hormones and not their nervous system. Females also change colors when they are pregnant or want to warn away males. Though chameleons are not the only organisms that can change color, they are among the fastest that can. Next, are the eyes of a chameleon. Their eyes are large and sit on the side of their heads. They are able to move separately and almost view 360 degrees of their surroundings (Foden, 2014). They are also able to move their eyes around without moving their heads. Another feature is their tongue. A chameleon’s tongue can be one and a half times longer than their body. When it is not extended, it sits coiled inside of their neck. They are able to extend their tongues to catch insects without being noticed, and the insects stick to it making it easier to catch. The fourth feature of a chameleon is their feet. Each foot has five toes. The feet in the front has two toes going outward and three toes going inward, while the back feet are the opposite. Their feet help them to grip braches to climb and stay mobile. Lastly, is a chameleon’s tail. Their tail is used for gripping while moving and to maintain their balance. When a chameleon feels threatened they can coil it, or roll it up, to make them appear larger while defensive. The inner structure of chameleons is also important in survival, ii (Neumann). They consist of a heart, oesophagus, lungs, liver, intestine, fat bodies, gal bladder, kidney, and cloaca. Females also have ovaries and oviducts for reproduction. They have a skeletal system that includes a very unique and important bone, the hyoid, iii (Terraristik). The hyoid is the bone that is connected to their  tongue. When chameleons extend their tongues you will notice that up close the bone’s outline is seen through the tongue. The hyoid is also used against predators when a chameleon feels threatened. They will push it down to extend their throat out to give the appearance that they are larger. It is clear to see that chameleons have evolved and are able to use many techniques to defend off predators. They are able to use their bodies to communicate with one another and express their feelings. Chameleons are also able to survive in normal and some extreme climates and habitats. The myth of chameleons being able to blend in with their surroundings has clearly been proven to be the completely opposite, as they change to stand out. In conclusion, there are many species of chameleons that have been around for many years, but they have evolved greatly over time. i (Komeleons) ii (Neumann) iii (Terraristik) References Bishop, G.

The first one portrays   late autumn or early winter. It portrays a   dull, cheerless and gloomy landscape- leafless and bare trees, withered and yellowed leaves, branches of trees deprived of   all the usual music since the chorus of birds has   flown away. The poet compares himself with this cheerless landscape and seems to lament the departed glory and happiness of his   life. Similarly, in the second stanza the poet equates himself to a twilight which in its wake will bring about a dark, silent and long night full of deathlike chill. The third quartrain portrays another gloomy scene—afire getting choked to death under the wait of its own ashes Three quartrains and each one of them, sad gloomy and pessimistic.

Rituals And Beliefs In Venezuela

Rituals And Beliefs In Venezuela In Venezuela and around the world has had been developed endless medical specialties, psychological, science and technology very rapidly, in the same way and nearly at the same speed, also, has emerged a large number of beliefs, myths, religions that each day rises with a booming effect. In fact, in the XXI century these religions, beliefs and superstitious practices, such as witchcraft, they manifest themselves with a large number of followers and/or curious people that are consulted with the idea that the shaman, medium or wizard help them to solve their problems, whether physical, mental, economic or any other nature. Some people queried for evil or revenge from others who according to them are the responsible to the origin of the conflict, and then there are those still without ever having attended a witchcraft ritual or religion and they are usually followers of Christianity or Catholicism, those people express to believe or to be under the effects of a work of magic and / or sorcery, or have a firm belief that witchcraft is real and something to be fear of. We often hear from these people phrases like I dont believe in witches, but if there are, there are, or with the Saints do not play (referring to Santeria which is a syncretic cult of witchcraft). Santeria: A religion that combines beliefs of the Yoruba and Bantu people of Southern Nigeria, Senegal, and the Guinea coast with elements of Roman Catholicism, with roots in the Caribbean. Donnelly (2005:65) explains how in this century Venezuelans increasingly break with a series of taboos imposed from the Spanish conquest about customs and religion, which opens a new door to the practice of rituals, spiritualism and occultism, being a heritage of ancestors, natives and slaves of the past. This cultural legacy, talking about occultism, rites and religions intermingle to combine religion, magic, occultism, between the sacred and pagan, between the rational and irrational, is to give a deeper meaning to life or tangible and its problems, is to looking for a closer God and not abstract or distant one. (Marin,1986:27). Because many of the religious practices and beliefs are transmitted by oral tradition, such as Santeria, they have not established a clear basis; in fact many of these religions and pseudo religions are characterized by a complex process of syncretism that even today continues. According Gruson (1970:34), the most popular religion is Catholicism, where 80 percent of the population consider themselves Catholic, whether or not they are participants. The faithful believe in God, but he is far from this world, the rites are directed towards the saints, the Virgin and the Souls who are closer to the humans. Religion provides the afflicted people the solution of many problems, including physical and mental health; also it has recreational purposes (dances, parties), psychological (ego gratification, when a person has an important position in the ritual organization), social (cronyism) and medicinal (miracle cures). Popular religions believe in nature spirits and other supernatural entities, ghosts and miraculous goblins, this is considered Catholic and does not cause damage to the basic structure of religion. Private rites are secrets, they are done in time of crisis, performed with a single purpose, but the intention is to alleviate the problem of the client or do evil, while the public rites are rather linked to official Catholicism. A mixture between paganism and sacred characterizes popular Catholicism. The rituals and symbols of Catholicism often have a different meaning for members of the educated classes than lower class or humble peasants. Catholics go to church, but also they practice rites of Santerà ­a at spiritualist centres, at the same time they may visit the graves of folk saints, spiritual healers or get a consultation via Internet. Even in most TV channels is possible to watch programs of cartomancy, tarot, among others, with a considerable rating, over 7%. (IBOPE AGB Venezuela, 2010). For example, baptism is considered a rite that protects the newborn against all evil influences; the cross for example, contains powers to ward off evil spirits. Although the Christianization of the Indians and black slaves during the colonial era, many concepts and oldest religious practices were preserved, which could flourish outside of official Christianity, all this is embedded so strong on this culture, that some medical professionals recommend the use of spell against the evil eye and shingles (sufferings of religious connotation) (Molina,1947:90-110). There is no evidence of serious or reflective studies regarding the present topic, but it is interesting to note that religious and pagan is widespread in this country, rituals of witchcraft, sorcery, popular religiosity and Catholic beliefs has been mixed together; among the most common are Nigerian Santeria or traditional and Cuban santeria (Martin, 1983:74). The practice of psychotherapy in Venezuela is new, there are very few professionals in the country and it is not specifically regulated by any entity, except the Venezuelan Association of Psychotherapist (AVEPSI), located in the capital city Caracas and formed in 2009. The practice of this specialty in Venezuela is highly welcomed by the general public, but a continuous education and feedback from the therapist towards the client and vice versa, in areas such as clinical hypnosis, beliefs in the supernatural, myths and rituals are necessary. The therapist may face a diversity of situations, similar to those faced Carl Jung and referred in his thesis On the Psychology and Pathology of So-Called Occult Phenomena (1902) in which he describes a young woman apparently suffering supernatural attacks. According to the previous explanation, surges a need to do a study that lead to answer the following question: Does beliefs; religious or esoteric practices of Venezuelans influence the psychotherapeutic practice in Venezuela? From the above question arise the following objectives: General objective Describe the influence of religions, beliefs, magic and witchcraft in the practice of psychotherapy in Venezuela SPECIFIC OBJETIVES Identify religious beliefs, magic or witchcraft on patients attending psychotherapeutic consultation. Estimate approximately the practice of religious rituals, magic or witchcraft in clients attending to psychotherapeutic consultation. Recognize the efficiency of Psychotherapy Techniques in the treatment of clients with religious tendencies or witchcraft practitioners. CHAPTER I Theoretical Framework Rites and Beliefs in Venezuela Some scholars take the practice of witchcraft in Venezuela as somewhat folkloric (Cazabone, 2009:89) unlike other countries where some rites have diabolical connotations with animal sacrifices involved. This folkloric aspect is closely linked with the Venezuelan humorous character, who in general do not take very seriously the powers of magic; the just in case, or I dont believe in witches, but if there are, there are, gives a sense of belief in certain aspects in the occult. Branch (in Zalazar et al, 2001:67) concluded that this Venezuelan way of be is a historic stereotype, derivative from miscegenation and the character of the participants on it, highlighting the ingenuity of indigenous, the hard labour of black workers and the conquerors arrogance. These archetypes explains Branch, play an important role to explaining the Venezuelan people characteristics , concluding that the Venezuelan broadly is cheerful and humorous by its black and Spanish heritage, smart for his Spanish and Indian roots, loving and generous the Indian heredity, but by the other hand, the negative side, lazy by the Indian essence, disorganized and wasteful by their black ancestry, disrespectful to the law and violent by the Spanish origin, nevertheless none of these influences have or are backed by scientific evidence, are simply social images that continue to be relevant (Zalazar et al, 2001:89). Moreover, beliefs and magic-religious practices are a privileged means to express realities, conflicts, emotions and hidden feelings, taking place beyond the ability to be rational. Christian (2009:30-45) explains that a great number of people light candles to different deities (Black First, Philip Black, Guaicaipuro, Maria Lionza, etc.) In order they may grant miracles or favours. This use of gadgets is a psychological strategy, Figueroa (2005:82) explains that humans use to control their lives and overcome their limitations in an environment that sometimes exceeds his capacity for understanding and action. Moreover, the use of talismans and / or amulets or just called vulture seed, the aloe plant are used in rituals and cults as a means of protection or lucky charms. Cabazone (2009:97) describes that the leader and ex-president Romulo Betancourt said with an air of certainty that his pipe was put under spell by a witch, and many believed that this was the key to its success. Magic and all its techniques is one of these resources and sometimes this faith on a ritual or belief generates spectacular solutions. Figueroa (2005:89) suggest, that the use of talismans and amulets dates from the ancient times and worldwide great men, politicians, artists, soldiers, athletes, etc., have behaved and carry symbols of good luck, giving high regard to the power of positive suggestion, so have been able to accomplish their purposes. The psychological effect makes believers to have faith on the amulet, rite, or talisman. The role of religion in Venezuelan culture and beliefs As discussed, the cultural background and miscegenation have been influential in Venezuelan culture, even on the whole Latin America despite an apparent secularization. Notably, worldwide, all cultures of the world were shaped by religion, no one ethnic group escapes this process and on the same area, magical religious traditions and customs have influenced significantly in social relationships, community life and moral codes, this faith in supernatural beings is evident not only in Venezuela but throughout the world (Pollak-Eltz, 2004:69). In Venezuela and throughout Latin America, Catholicism, shaped the culture that until recently had absolute monopoly; all social classes were influenced. Today the official and popular religions are expressions of different types of lifestyles, on the one hand, traditional or popular religiosity has curative and magical and is generally practiced by popular sectors and secondly official Roman Catholicism practiced by people in urban areas. In this sense, the proliferation of rites and beliefs and personal interpretations of followers and practitioners and the lack of a defined priestly liturgy make these practices and cults an easy target of charlatans and abusers. Among the most popular cults is that of Maria Lionza, in which the medium is possessed he or she fall in trance (matter) and them the spirit that possesses the person is consulted and this gives advice to the person seeking help. The cult of Maria Lionza is complex and covers all magical and religious beliefs of Venezuelan people and forms a synthesis of magical practices, within a religious context. (Pollak-Eltz, 2004:82). Can be said that this is a syncretic cult with practical solutions through rituals that recognize the values of Christianity, in fact, Maria Lionza is sometimes identified with the Virgin of Coromoto and/or an indigenous spirit. Magic is present on this cult and its techniques are neither good nor bad, but can be used for do good or evil. Wizards pretend to manipulate those forces and claim to possess supernatural and extraordinary powers to communicate with the supernatural world (matter). Pollak-Eltz (2004:83) states that Faith is the cause of miracles. Because these techniques can be learnt, the magician is not responsible for acts performed; he or she is an officer to whom the client pays their services. This magician or medium often has the knowledge to solve problems and cure diseases, and is an excellent psychologist despite his limited formal education. According Pollak-Eltz (2004:106) or pagan religion of witchcraft was faded from the countryside to the cities. This culture is broadly Christian and despite advances in technology and medicine is popular religiosity more alive than ever, and thats because the popular religion is utilitarian, giving spiritual support and serves as a psychological calming in times of personal crisis. Saignes (in Pollak-Eltz 2004:65), states that Historically, whites and slaves used to consult black healers that often had more success than white surgeons in healing the sick. Their knowledge on medicinal plants and magical rites brought a increased the prestige of the African medicine-men. This figure of the magician or sorcerer could be seen as the representation of an idol, which has the privilege to channel and guide the prosperity or misfortune at will of others. This is reflected according to Rojas (2006:30), in the particular character of Venezuelan people when they worship a person or religious figure on which can be trusted and surrender. Popular Religion The misfortunes and influence that the church had in the 19th and 20th has no relevance in how Venezuelans built his ideas about faith and deities. Since colonial times, this unique blend between religion and popular religion came framed on a profound mystery of the supernatural and esoteric (Gackstetter et al, 2010:45). There is a term called The three powers, has nothing to do with the Catholic Trinity. Maria Lionza is symbolized as the Virgin Mary, these represent the three main components of the country identity, in other words, European, African and indigenous. On this court of spirits enters Simon Bolivar (liberator of Venezuela from Spanish rule) Andrà ©s Bello, Negro Felipe (First Black, a black slave who was also murdered by the colonists), Negra Matea (Bolà ­vars nanny), Jose Gregorio Hernandez and other Catholic saints. The cult of Maria Lionza is not a religion guided or hierarchical; the shaman or mediums simply ask questions to the believers about their families, problems, disputes, financial problems, or medical problems. Sometimes people who seek help and have a relative in jail, seek help from Juan Vicente Gomez, those political questions do through Simon Bolivar. Believers generally have a high intensity of spiritual devotion, and made a pilgrimage to Sorte Mountain (near Chivacoa in Yaracuy State) with the belief that the goddess will solve the situation or mishap. Believers choose a corner in the woods or a bend in the river to build an altar from which invoke, this is called portals. Usually is decorated with photographs, figures and figurines, glasses with rum or brandy, cigars, cigarettes cross, flowers and fruits. There are several versions of this legend. One of them says that a green-eye Indian woman called Yara was baptized as Maria del Prado of Talavera de Niva. The Cacique Yaracuy sent her to the mountains where it is said she rode on an ounce (leopardus pardali). So Mary was called the Onza and then Maria Lionza. It is believed that her cult was born of devotion to the forces of nature and the spirits of the rivers, jungles and caves. Maria Lionza is part of a trinity along with Guaicaipuro, an Indian chief murdered by the Spanish colonists, and Negro Felipe. These three saints are the leading figures of the cult and lead several courts of lesser deities. These courts are: The Indian Court led by Marà ­a Lionza and composed of many Venezuelan Indian chiefs. The Medical Court led by Josà © Gregorio Hernà ¡ndez and composed of many other famous doctors. The Court of the Juans made up by a number of figures belonging to Venezuelan folklore. The Teachers Court led by Andrà ©s Bello and some other authors. The Black and African Court, led by popular black figures of Venezuelan history such as La Negra Matea (who was a slave to the Bolivars and nanny of Simà ³n Bolà ­var), and El Negro Primero (Pedro Camejo) who was known as Negro Primero because he was black and also among the first to go into combat. The Celestial Court composed of a number of Catholic saints. The Political Court, which includes Simà ³n Bolà ­var. The Court of Malandros, made up of deceased criminals. The Viking Court, with various of the important Viking chiefs. Maria Lionza has had a great social and cultural significance that transcends their followers. Her cult was unveiled outside Yaracuy to the 50s of last century, when in 1953 during the tenure of General Marcos Pà ©rez Jimà ©nez, the sculptor Alexander Hill (1901-1953) built the famous sculpture of Maria Lionza on a Tapir, (Tapirus terrestris), which has been for over 50 years on the Eastern Freeway in Caracas. On this cult nothing is written, is transmitted orally from generation to generation (cited in http://www.rnw.nl/espanol/video/cultos-populares-venezuela-adoraci%C3%B3n-de-mar%C3%ADa-lionza., 2021). Most relevant Churches and cults in Venezuela Among religious organizations and cults largest in the country are: (source: Directorate of Religious Affairs of the Ministry of Justice in Venezuela,1989). 1. Protestant or Evangelical: After the Diet of Speyer* or Diet of Spires protest in 1529, there was no intention of proselytizing in Latin America, neither to the evangelizing mission. The main interest was focused only on the Reformation, which resulted that Protestantism could not take root in Latin America until the mid-nineteenth century with little success. However, over the years the indicators have changed, even the statistics of late twentieth century are really growing not only in terms of evangelical denominations but also on other spiritualistic denominations. They are grouped into the following: a. Anglicanism. b. Presbyterian Church c. Lutheran Church. d. Baptists. e. New Tribes Mission. *Diet of Speyer or Diet of Spires refers to any of the sessions of the Imperial Diet of the Holy Roman Empire, of which 50 took place between 838 and 1570 in the city of Speyer (Spires), now in Germany. The most famous sessions occurred in 1526 and 1529 (Wikipedia 2011). 2. Confederate Evangelicals: Religious currents coming from the United States and has Christian connotations. 3. The Pentecostals: They represent a rapidly growing movement with unique characteristics. This religious movement is marked by Methodism and the American Baptists. Pentecostals came to Venezuela in 1940, and its founder the Rev. Irvin Olson, an American Baptist who chose Barquisimeto as pilot center to establish the first Assembly of God in Venezuela. Then extend his work to Caracas the capital city and Falcon. 4. Pseudo Christian religion or Millennialists: These religions tend to grow easily. They have in common that their founders made a personal interpretation of the Bible, creating a new dogma around it, which means, to give different meaning to the tradition, followers believe to have the absolute truth (Mangas and Montero, 2001:110). In Venezuela there are three organizations: The Seventh-day Adventist Church (SDA), Jehovahs Witnesses and Mormons, the latter without registration within the Directorate of Justice and Religion. a. Seventh-day Adventists Church. b. Jehovahs Witnesses. c. Mormons. 5. Spiritual Centre: Its the Venezuelan significant inclination toward the esoteric, rituals and astral. It is not based on beliefs but on personal needs. This conciliation between the sacred and the profane has its essence in animism and polytheism primitive Strengthened by the African Christian cult with an apparent institutionalism. The Indians embraced the faith of the Catholic Church, but the survival of their beliefs and their closeness to the African slaves produced that Kind of new beliefs. 5.1. The popular indigenous court: This tendency is associated to aboriginal elements. For example, the Indian man thought on the power of natural phenomena, on the stones, lakes, rivers, and the acquisition of that supernatural power conceived by their gods. These beliefs were transmitted to subsequent generations and were fed by transcultural elements including Santeria and Spiritualism. There is no hierarchy that identifies these elements on the contemporary society. What for the Indian was a deity for the healer now is a means of economic livelihood and it is seen as a company with excellent clientele. 5.2. Spiritualists: Along with santeria, this is one of the most advanced forms of mysterious beliefs based mostly on spiritualism of Allan Kardec, French teacher and educator. He is known today as the systematizer of Spiritism for which he laid the foundation with the five books of the Spiritist Codification. It is believed that Spiritism entered to our country under the influence of immigrants from Brazil and Colombia, product of oil fever. There is no hierarchy around which are organized. The chief head leads the worship and is invoking otherworldly beings, becoming the medium and are called to perform miracles, healings, among others of its kind. 5.3. Santeria: This form of religion is more complex than others. There is a mix of indigenous elements with spiritualist elements, African and Christian origining a semi-organized hybrid. This religion takes the structure of an ancient African tribal religion of the coast of Nigeria, and has three priestly orders: the babalaos, the Orishas ministers and priests of a particular deity. African slaves brought this religion and their main centres are in Brazil, Cuba, and Haiti, subsequently gaining followers in Colombia and Venezuela (Gonzalez-Wippler, 1989:45). The Santeria in Venezuela have made an even greater mixture, they have found an equivalence between the African gods with Catholic saints, so, for example, Chango (god of lightning and thunder) has its equivalent on Santa Barbara, Oshun (river goddess) at Nuestra Seà ±ora de la Caridad del Cobre (Our Lady of Charity of Copper) and so on, giving a deity character to popular saints like Jose Gregorio Hernandez, Maria Lionza, Negro Felipe, among many others. To the priests formation a kind of tutor is assigned, who is responsible to teach the apprentice all mysteries and then a new priest is ordained. They prepare their ceremonies at sites near rivers or on a mountain as located at Sorte, Yaracuy. Once ordained, the priest is ready to heal, and to remove evils spirits, that acording to them are the ones who tie the individual. Constants pilgrimages are made from inside the country to Sorte Mountain. There are transport companies that offer their services to the mountain, plus a large number of ordained priests, commonly called doctors or sorcerers, who organize these trips from their centres. It will be noted that trade (merchandising) around these cults is prosperous (consultations, travel, esoteric products, candles, text, perfumes, etc). 5.4. The cult of Maria Lionza: The cult of Maria Lionza comes to represent the formation of a Venezuelan indigenous religion with elements of other cultures, in which prevails the origing of the worship of a deity indigenous enriched with Africans religious culture and spiritualism. 6. Sects 6.1. The Moonies: The name usually are due to its founder Sun Myung Moon, born in North Korea in 1920. The organization has the official name of Association for the Unification of World Christianity (AUCM) and aims to create a society based on the seeding of spiritual values and on the driving of the family towards real peace. 6.2. Scientology: Its founder is the American Lafayette Ron Hubbard (1911-1986), a specialist in 25 professions in which stand out those of the writer of science fiction (65millones of copies sold of the book The Way to Happiness and screenwriter) . The church is considered a company in all aspects. They have a very distinct structure. Its principles are based on the Dianetics which consists of the individual healing itself freeing the enslaved spirit. The procedure to achieve this end is by attending sessions called audition where the individual is subjected to purification by employing a tool called electropsychometer device that detects areas of spiritual distress. This method is progressive. The initiate discards their old beliefs and acquires new rules that he/she must comply according with the amount of promotions obtained. 6.3. Eastern Syncretism: Unlike the animadversion generated in Venezuela during a good part of twentieth century the sects, today are accepted and a significant number of Venezuelans profess parallel and simultaneously in their religion some of these beliefs. It is common to hear things like this: I am a Catholic but I received the tao or I am a Catholic but I like going to the talks of Buddhist metaphysics. All this is due to the openness of the Eastern sects who reconciled Christianity with their religious precepts and the openness of Venezuelan society to allow several beliefs coexist with both. The use of ritual in psychotherapy as a tool for change The use of rituals is an effective tool in some patients on the practice of psychotherapy in Venezuela and is often the only way to convince the patient that his mind can be healed, free from beings, spirits, influences, or spells that threatening the physical and mental health of the person. The ritual was always an issue discussed by anthropologists who have described the customs and rituals of peoples and communities. Its therapeutic efficacy for change has been described by many clinicians in systemic literature (Ochoa de Alda, 1995:89). Notably rituals are not heritage of therapists, but procedures of the peoples, families and cultures. An important point is that, in practice as therapists, it should take into account the importance of these phenomena on individuals and families who participate in these traditions (and any other), and knowing these procedures, that are made spontaneously it may arise new ideas for generating alternatives that can be used on a therapeutic context, in order to try to encourage changes that help to get a more adaptive performance, not symptomatic, of families and individuals who, because of their suffering, come to seek therapy. In addition, and of course, as an element well worked, can provide substantial information, especially relational. In psychotherapy is considered that a ritual includes a set of actions and / or symbolic interactions more or less structured, they are not restricted only to the completion ceremony, but include the entire process of preparation, the implementation experience and reintegration back to everyday life (Rappaport, 1971:12). A ritual must be composed of the following elements: symbols, open and closed parts and the need to be developed in a space and in a special time (Whiting, 1991:56). The symbols or symbolic actions are the minimum element would constitute a ritual. The link to the meaning of the symbol that appears is usually a personal construction, family or social. Besides rituals symbols consist of open parts and closed parts together. The enclosed parts are the parts of unchanging ritual common to all performing the ritual, these parts provide the minimum structure rigid enough to reassure strong emotional components, transmit important values and give concrete form to the shares. Instead open parts provide sufficient flexibility for each of the participants in the ritual hand contribution to personal and idiosyncratic experience. In the rituals with an important cultural root is usually prescribed by tradition the place and time that will be the realization of the ceremony. The symbols or symbolic actions are the minimum element that would constitute a ritual. The link of the symbol regarding to the meaning that appears is usually a personal construction, family or social. Besides symbols, the rituals consist of open parts and closed parts that are joined. The closed parts are the parts of unchanging ritual common to everyone who is performing the ritual, these rigid parts provide the minimum structure enough to bring security against strong emotional components, transmit important values and give concrete form to the actions. Instead open parts provide sufficient flexibility for each of the participants in the ritual and the possibility that each one can make his/her contribution according their personal and idiosyncratic experience. The rituals, which have an important cultural root, are usually performed following the tradition, on the place and time specific to the achievement of the ceremony. Type of rituals Rites of passage or transition rituals: described in 1909 by A. Van Gennep. These rituals are performed in the transitions experienced by individuals and groups throughout the life cycle, marking the end of a stage of development and the beginning of a new one. Van Gennep after studying various cultures argues the universality of such rituals. Continuation: rites of intensification. Unlike the transition rituals that are usually performed only once in life of every individual, continuity rituals are executed repeatedly, their purpose is to set the pace of life and maintain continuity, normality within each stage of life cycle. Healing rituals: This would include the rituals performed to cure, heal and keep out certain diseases. Therapeutic Rituals: This includes rituals developed by therapists and used in psychotherapeutic practice, nevertheless psychotherapy may be considered in some cases as a ritual. Haley (1973) considered the treatment that is carried out to treat certain problems and that arise in adolescence (psychosis, behavioural disorders, anorexia) is like an initiation ritual, through which it promotes individuality and necessary emancipation required from the young, as a way to restore him or her to a normal life cycle. Functions of rituals: Ochoa De Alda (1995:56) explains that the main functions that meet the rituals described in the life of societies, peoples, families and individuals are: Rituals make life predictable, providing a sense of belonging to the group that affects the sense of identity of individuals that form it. Rituals, does order and regulate the social functioning, confirming the social structure, while promoting an evolution in this with minimal conflicts. Another primary function is the transmission of culture, values and lasting norms. By one hand, it does create a sense of solidarity, cohesion and continuity in groups, and on the other hand, contribute significantly to the creation of the belief systems of a group (Van der Hart, Voogt and Witzum, 1989:56). The traditional rituals not only channelled social coordination between individuals, families, communities and villages in the here and now, but also between the past, present and future represented by the different generations (Davis, 1987:67). The rituals of transition, allow passing from one stage to other on the life cycle. Its first element of action does that roles, relationships, and world standards are modified during their execution (Davis, 1987:78). Admitting that any transition is to a greater or lesser extent an imbalance, ritual ceremonies

Physics of Rainbows :: physics rainbow weather

Imagine a sky full of dark fluffy clouds. The air feels wet and sticky, and rain drops begin to fall. Soon the drops become a sheet of rain and this makes you sad because your outdoor fun is over. But, just as you turn your back to go inside, you feel the sun break through the clouds and warm your back. A smile fills your face because you realize that rain plus sun equals a rainbow. You turn around to see a glorious rainbow in the sky. As you gaze, questions begin to pop into your head. What are rainbows? Who are some scientists that studied them? What makes the colors? Why is there a double bow? So what are rainbows? It might be easier to start with what they aren't by clarifying some common myths about them. * "There is an end to the rainbow." -- This is not true. A rainbow is relative to the observers position. Because of this, as an observer moves, so does the rainbow. This means that the "end" moves as well, and can never be found. Also once the sun has disappeared or the observer turns to face the sun, the rainbow disappears. * "There is a pot of gold waiting for me at the end." -- For the resaons stated above, there is no end. Because there is no end, well...there is no gold. Sorry! * "Rainbows are real physical tangible things."-- Rainbows are optical illusions. They are something that a person can see, but are not something that a person can really touch. If Rainbows aren't real...and there is so end to them...and therefor no gold....so what is a rainbow if it's not a magical gold giving wonder? * According to Websters Dictionary "A rainbow is an arc containing the colors of the spectrum formed in the sky by the refraction, reflection, and dispersion of light in rain or fog." * Rainbows are an optical illusion. -- As stated before, they are an illusion and are dependent on the observers point of view. When it starts to rain and an observer has his back to the sun, refraction, reflection, and dispersion occurs and a rainbow is most likely to be seen.

Cyrano De Bergerac :: Cyrano De Bergerac Essays

Cyrano de Bergerac   Ã‚  Ã‚  Ã‚  Ã‚  Every generation has its own heroes that display what they believe to be idealcharacteristics. While each is different in their own way, many of these role models share similarqualities. Most tend to have courage, strength, compassion, or another respected trait, but this isnot necessarily why they win the adoration of their followers. Cyrano de Bergerac is a perfect and ideal “chevalier servant';, or to put it in simple terms, a perfect example of how many protagonistswin our allegiance because his sensibilities will not be denied. Mainly because he lives life to thefullest, and because he is a victim of his surroundings.If there ever was a figure in this book who would be the ideal “chevalier servant';, it isCyrano. When lovers admit, “I’d die for you';, it is usually taken as a figure of speech. Cyranoactually crossed over enemy lines every day simply to mail love letters. He also confessed toRoxane, “My mother made it clear that s he didn’t find me pleasant to look at. I had no sisters.Later, I dreaded the thought of seeing mockery in the eyes of a mistress. Thanks to you, I’ve atleast had a woman’s friendship, a gracious presence to soften the harsh loneliness of my life.';When he then admits, “My heart always timidly hides its self behind my mind';, the reader can instantly relate to this dilemma but it is the fact that Cyrano is able to overcome it, then thatmakes him the ideal “chevalier servant';.Not only is Cyrano filled with emotion, but he also goes out of his way to live life to the fullest. Cyrano’s introduction to the reader definitely leaves a lasting impression. Not only does he banish an actor from the theater for performing poorly, but he proceeds to recite poetry while dueling with another member of the audience. Every moment of Cyrano’s life is filled with action like this. When he was informed that one hundred men were going to try and kill his frien d, Ligniere, he was trilled with the idea of fighting all these men at once, and, of course, he succeeded. How could anyone not love this man who takes “Carpe Diem'; to its most extreme form? Also, Cyrano is a victim of his surroundings. This may be the one characteristic that completely wins over the reader. Cyrano’s most obvious flaw is his grotesque nose, but this would not be so awful if the people around him didn’t care.

Quantum Teleportation Essay -- quantum physics teleport

Quantum Teleportation is one of the newest areas of study in the field of quantum physics. It is the stuff of science fiction, which is fast becoming reality, where solid objects can be moved vast distances instantly. It has been the subject of books and movies for years but it wasn’t until recently that physicists at IBM’s laboratories made it a reality. The ideas that formed the basis of these experiments came about from previous research by scientists such as Albert Einstein and Heisenberg. This essay will explore the research done on this subject, the theories behind it, and the possible applications. Quantum teleportation is the idea that transporting matter can be achieved instantaneously by taking advantage of certain aspects of quantum physics. It is not possible to actually transport the matter, but rather, the properties of the object being transported can be applied to matter in a separate location. This newly created object is identical to the original down to the state of the individual atoms, and so is in effect the same object. The original object loses its properties during the process and is, in effect, destroyed. This takes advantage of the Einstein-Podolsky-Rosen correlation (Quantum), also referred to as entanglement. When two particles are entangled they take on properties identical to each other regardless of separation. This means that if something alters one of the entangled pair it affects the other in the exact same manner. In order to transport something we have to start with one of these entangled pairs. One particle at the source location and one at the location we want to transport the new object to. We then take a third particle, which is what will be transported, and measure it in relation ... ... in the field of computing. Because computers operate on a binary system it is possible that individual quanta cold be used to store information. This is possible because quanta can be in two states, horizontal and vertical. Using quantum teleportation information can instantly be sent from one point to another. An example of quantum computing could be if a person had to search a dorm for a specific item. Normally the person would have to go to every door in turn and look inside but if this were a quantum computer doing the searching it could look in every room at the same time.

Face Recognition Study: Inverted V Upright Faces. Essay

Face recognition study: Inverted V Upright faces. Introduction: Face recognition is a difficult visual representation task in large part because it requires differentiating among objects which vary only subtly from each other. This particular face recognition study was expected to suggest that people recognise inverted faces less accurately than upright faces. The study involved sixty different faces observed on a computer screen by a sample of first-year university students. Hypothesis: The hypothesis for this study stated that it is expected that people recognise inverted faces less accurately than upright faces. The null hypothesis stated that there would be no difference in the amount of faces recognised regardless of whether they were upright or inverted and that if there was to be any difference that it would be down to chance. Method: Participants: The sample used consisted of 15 first-year psychology students of mixed ages. Gender or race held no significance for this study. The psychology students used participated in the experiment in there seminar groups at allocated times throughout a timetabled week. Materials: The materials used for this study consisted of the e-pro computer programme which was used in order to display the faces required for the experiment. Furthermore, the results of the study were interpreted using the SPSS computer software. Procedure: For the first part of the experiment, sixty faces, thirty of which were upright and thirty of which were inverted were displayed on a computer creen for two seconds per face. After each participant had viewed the full sixty faces, a distracter task was then issued to them in order to remove any short-term memory effects on facial recognition. The distracter task consisted of a series of personal questions and lasted for roughly five minutes. Upon completion of the distracter task, the second part of the experiment took place. During the second phase of the experiment, sixty of the previous faces w ere shown alongside a set of sixty new faces. Participants were asked to say whether or not they recognised the faces from the earlier stage of the task. Results: The mean number of recognised inverted faces was 0. 67 with a standard deviation of 0. 07. The mean number of recognised upright faces was 0. 74 with a standard deviation of 0. 05 ? Figure 1 shows the mean value for facial recognition of upright faces to be significantly higher than that of inverted faces: t(14) = 3. 55, p= 0. 03 Figure 1: Mean values of facial recognition for inverted and upright faces. Discussion: The results recorded from this study suggest that our hypothesis that people recognise inverted faces less accurately than upright faces may be correct. However, to be more certain that our hypothesis is accurate, it should be ensured that the experiment is repeated and that in this instance is counter-balanced across the whole sample of first-year psychology students collectively and not just within their seminar groups.

A1 Steak Sauce Essay

1) How would you characterize the A1 Steak Sauce business? In 1830, Henderson William Brand, chef to England’ King George developed a sauce that so delight the king he proclaimed it to be â€Å"A1†. The product was first sold in North America in the early 1900s. Kraft Foods acquired A1 in 2000 as part of its acquisition of Nabisco. Kraft Foods was the largest food company in the United States and second largest in the world. Kraft Foods most direct competitors were General Mills, Unilever, Pepsico and Nestle. In 2002, A1 had a 54% dollar share of the Steak Sauce Market Shares with an 83 percent gross profit margin. Distribution of A1 stretched across the United States with the product available in every grocery store. Kraft Foods spent 15 percent of its operating revenue on A1 advertising. Revenue on A1 Steak Sauce was about $150 million and operating profit was approximately $60 million. A1’s 2003 plan anticipated flat revenue and slight profit growth. 2) Why is Lawry’s launching a steak sauce product? Explain. In 2002, Lawry’s was owned by Unilever one of Kraft Foods leading competing food companies with brand sales in excess of $100 million and a strong position in seasoning and marinades. In early 2003, Unilever announced plans to launch a Lawry’s Steak Sauce with a ship date of April 1st and a price per bottle $1.00 less than A1. Unilever’s decision to launch a steak sauce product was based on disappointing financial results in recent years.  Unilever launched a new strategic plan program called â€Å"Path to Growth†. A key element of this program was rationalizing its brand portfolio focusing on the largest global brands. The company challenged all of its brands including Lawry to reach annual sales of at least one billion dollars. 3) Should A1 Steak Sauce defend itself against the Lawry’s launch? If not, why not? If yes, why and how? Discuss. Jennifer Miller, Smith’s research manager statement of â€Å"you know A1 has the strongest brand equity in the category, it’s virtually untouchable.† I don’t agree and feel her comment is unrealistic, nothing is untouchable. I would recommend that A1 defend against Lawry’s Steak Sauce launch scheduled for April 1st, otherwise A1 could find they are losing market shares and trying to play catch up. In my opinion A1 has a choice to compete head-to-head with Lawry’s 2 for $5.00 deal launching on April 1st or sit back and hope that consumer don’t switch to the Lawry’s Steak Sauce. Either way A1 will have to spend money to remain dominant and competitive in the steak sauce market. 4) What are the competitive and financial implications of defending or not depending against the Lawry’s launch?  Lawry is scheduled to launch their new steak sauce of April 1st at $1.00 less than the A1 sauce and Publix is ready to give Lawry the Memorial Day week promotion which is normally 10 percent of A1 Annual Sales. If Lawry, does gain 10 percent of the steak sauce  market and customers like the taste, willing to pay the reduced price regardless of taste or can’t really tell the difference in taste from A1, customers might continue to buy the Lawry’s Steak Sauce for the $1.00 cheaper bottle. Lawry’s Steak Sauce launch could allow them to gain and increase in Lawry’s share in the steak sauce market. 5) What did you learn from your analysis of this case? Explain. A1 Steak Sauce was invented in 1830 and first sold in North America in the early 1900s. In 2003, over 100 years later, A1 Steak Sauce finally had potential competition with the launch of Lawry’s Steak Sauce. I feel that Kraft Foods should have planned for such a contingency that to me was inevitable. If they had planned, the company could have properly budgeted, maybe with a contingency type fund within the marketing department. For example, today where are reel-to-reel tapes, 8 track tapes and cassette tapes, all have become outdated with improvements in technology. To further illustrate in the food industry, try to find â€Å"Pitter Patter† peanut butter cookies made by Keebler which were out marketed by Nabisco’s â€Å"Nutter Butter† peanut butter cookies. Nothing is untouchable or lasts forever!

Should boys and girls be in separate classes? Essay

â€Å"Single-sex education can be especially harmful for children who do not conform to gender stereotypes. Peers are often the strongest enforcers of sex roles.

The Behavior Of Human Being Health And Social Care Essay

Methodology is a subject ; study the behaviour of human being in assorted societal scene. Harmonizing to Merton ( 1957 ) methodological analysis is the logic of scientific process. The research is a systematic method of detecting new facts for verifying old facts, their sequence, interrelatedness, insouciant account and natural Torahs that govern them. The scientific methodological analysis is a system of explicit regulations and processs upon which research is based and against which the claim for cognition are evaluated. This subdivision of the survey edifying the description of the survey country, definitions of stuff used methods to accomplish the aims and indispensable parts of the present survey.3.1 Data Collection:The information is collected by carry oning a study so that those factors can be considered which were non available in the infirmary record and were most of import as the hazard factors of hepatitis. The study was conducted in the liver Centre of the DHQ infirmary Faisalabad during the months of February and March 2009. A questionnaire was made for the intent of study and all possible hazard factors were added in it. During the two months the figure of patients that were interviewed was 262. The factors studied in this study are Age, Gender, Education, Marital Status, Area, Hepatitis Type, Profession, Jaundice History, History of Blood Transfusion, History of Surgery, Family History, Smoking, and Diabetes. Most of the factors in this information set are binary and some have more than two classs. Hepatitis type is response variable which has three classs.3.2 Restrictions of Datas:In the outline it was decided to take a complete study on the five types of hepatitis but during the study it was known that hepatitis A is non a unsafe disease and the patients of this disease are non admitted in the infirmary. In this disease patients can be all right after 1 or 2 cheque ups and largely patients do n't cognize that they have this disease and with the transition of clip their disease finished without any side consequence. On the other manus, hepatitis D and E are really rare and really unsafe diseases. HDV can hold growing in the presence of HBV. The patient, who has hepatitis B , can hold hepatitis D but non the other than that. These are really rare instances. During my two months study non a individual patient of hepatitis A, D and E was found. Largely people are enduring from the hepatitis B and C. So now the dependant variable has three classs. Therefore polynomial logistic arrested development theoretical account with a dependant variable holding three classs is made.3.3 Statistical Variables:The word variable is used in statistically oriented literature to bespeak a characteristic or a belongings that is possible to mensurate. When the research worker measures something, he makes a numerical theoretical account of the phenomenon being measured. Measurements of a variable addition their significance from the fact that there exists a alone correspondence between the assigned Numberss and the degrees of the belongings being measured. In the finding of the appropriate statistical analysis for a given set of informations, it is utile to sort variables by type. One method for sorting variables is by the grade of edification evident in the manner they are measured. For illustration, a research worker can mensurate tallness of people harmonizing to whether the top of their caput exceeds a grade on the wall: if yes, they are tall ; and if no, they are short. On the other manus, the research worker can besides mensurate tallness in centimetres or inches. The ulterior technique is a more sophisticated manner of mensurating tallness. As a scientific subject progresss, measurings of the variables with which it deals become more sophisticated. Assorted efforts have been made to formalise variable categorization. A normally recognized system is proposed by Stevens ( 1951 ) . In this system measurings are classified as nominal, ordinal, interval, or ratio graduated tables. In deducing his categorization, Stevens characterized each of the four types by a transmutation that would non alter a measurings categorization.Table 3.1 Steven ‘s Measurement SystemType of Measurement Basic empirical operation Examples Nominal Determination of equality of classs. Religion, Race, Eye colour, Gender, etc. Ordinal Determination of greater than or less than ( ranking ) . Rating of pupils, Ranking of the BP as low, medium, high etc. Time interval Determination of equality of differences between degrees. Temperature etc. Ratio Determination of equality of ratios of degrees. Height, Weight, etc. Variable of the survey are of categorical in nature and holding nominal and ordinal type of measuring.3.4 Variables of Analysis:Since the chief focal point of this survey is on the association of different hazard factors with the presence of HBV and HCV. Therefore, the person in the informations were loosely classified into three groups. This categorization is based on whether an person is a bearer of HBV, HCV or None of these. Following table explains this categorization.Table 3.2 Categorization of PersonsNo.SampleHepatitisPercentageI 100 No 38.2 Two 19 HBV 7.3 Three 143 HCV 54.6 Entire 262— –1003.4.1 Categorization of Predictor Variables:Nominal type variables and cryptography is: Sexual activity Male: 1 Female: 2 Area Urban: 1 Rural: 2 Marital Status Single: 1 Married: 2 Hepatitis Type No: 1 B: 2 C: 3 Profession: No:1 Farmer:2 Factory:3 Govt. :4 5: Shop Keeper Jaundice Yes: 1 No: 2 History Blood Transfusion Yes: 1 No: 2 History Surgery Yes: 1 No 2 Family History Yes: 1 No: 2 Smoking Yes: 1 No: 2 Diabetess Yes: 1 No: 2 Ordinal type variable and cryptography is: Age 11 to 20: 1 21 to 30: 2 31 to 40: 3 41 to 50: 4 51 to 60: 5 Education: Primary: 1 Middle: 2 Metric: 3 Fas: 4 BA: 5 University: 63.5 Statistical Analysis:The appropriate statistical analysis techniques to accomplish the aims of the survey include frequence distribution, per centums and eventuality tabular arraies among the of import variables. In multivariate analysis, comparing of Logistic Regression and Classification trees is made. The statistical bundle SPSS was used for the intent of analysis.3.6 Logistic Arrested development:Logistic arrested development is portion of statistical theoretical accounts called generalised additive theoretical accounts. This broad category of theoretical accounts includes ordinary arrested development and analysis of discrepancy, every bit good as multivariate statistics such as analysis of covariance and Loglinear arrested development. A enormous intervention of generalised additive theoretical accounts is presented in Agresti ( 1996 ) . Logistic arrested development analysis surveies the relationship between a categorical response variable and a set of independent ( explanatory ) variables. The name logistic arrested development is frequently used when the dependant variable has merely two values. The name multiple-group logistic arrested development ( MGLR ) is normally reserved for the instance when the response variable has more than two alone values. Multiple-group logistic arrested development is sometimes called polynomial logistic arrested development, polytomous logistic arrested development, polychotomous logistic arrested development, or nominal logistic arrested development. Although the information construction is different from that of multiple arrested developments, the practical usage of the process is similar. Logistic arrested development competes with discriminant analysis as a method for analysing distinct dependent variables. In fact, the current esthesis among many statisticians is that logistic arrested development is more adaptable and superior for most state of affairss than is discriminant analysis because logistic arrested development does non presume that the explanatory variables are usually distributed while discriminant analysis does. Discriminant analysis can be used merely in instance of uninterrupted explanatory variables. Therefore, in cases where the forecaster variables are categorical, or a mixture of uninterrupted and categorical variables, logistic arrested development is preferred. Provided logistic arrested development theoretical account does non affect determination trees and is more similar to nonlinear arrested development such as suiting a multinomial to a set of informations values.3.6.1 The Logit and Logistic Transformations:In multiple arrested development, a mathematical theoretical account of a set of explanatory variables is used to foretell the mean of the dependant variable. In logistic arrested development, a mathematical theoretical account of a set of explanatory variable is used to foretell a transmutation of the dependant variable. This is logit transmutation. Suppose the numerical values of 0 and 1 are assigned to the two classs of a binary variable. Often, 0 represents a negative response and a 1 represents a positive response. The mean of this variable will be the proportion of positive responses. Because of this, we might seek to pattern the relationship between the chance ( proportion ) of a positive response and explanatory variable. If P is the proportion of observations with a response of 1, so 1-p is the chance of a response of 0. The ratio p/ ( 1-p ) is called the odds and the logit is the logarithm of the odds, or merely log odds. Mathematically, the logit transmutation is written as The following tabular array shows the logit for assorted values of P.Table 3.3 Logit for Various Values of PPhosphorusLogit ( P )PhosphorusLogit ( P )0.001 -6.907 0.999 6.907 0.010 -4.595 0.990 4.595 0.05 -2.944 0.950 2.944 0.100 -2.197 0.900 2.197 0.200 -1.386 0.800 1.386 0.300 -0.847 0.700 0.847 0.400 -0.405 0.600 0.405 0.500 0.000— —— —Note that while P ranges between zero and one, the logit scopes between subtraction and plus eternity. Besides note that the nothing logit occurs when P is 0.50. The logistic transmutation is the opposite of the logit transmutation. It is written as3.6.2 The Log Odds Transformation:The difference between two log odds can be used to compare two proportions, such as that of males versus females. Mathematically, this difference is written This difference is frequently referred to as the log odds ratio. The odds ratio is frequently used to compare proportions across groups. Note that the logistic transmutation is closely related to the odds ratio. The contrary relationship is3.7 The Multinomial Logistic Regression and Logit Model:In multiple-group logistic arrested development, a distinct dependant variable Y holding G alone values is a regressed on a set of p independent variables. Y represents a manner of partitioning the population of involvement. For illustration, Y may be presence or absence of a disease, status after surgery, a matrimonial position. Since the names of these dividers are arbitrary, refer to them by back-to-back Numberss. Y will take on the values 1, 2, aˆÂ ¦ , G. Let The logistic arrested development theoretical account is given by the G equations Here, is the chance that an single with values is in group g. That is, Normally ( that is, an intercept is included ) , but this is non necessary. The quantities represent the anterior chances of group rank. If these anterior chances are assumed equal, so the term becomes zero and drops out. If the priors are non assumed equal, they change the values of the intercepts in the logistic arrested development equation. The arrested development coefficients for the mention group set to zero. The pick of the mention group is arbitrary. Normally, it is the largest group or a control group to which the other groups are to be compared. This leaves G-1 logistic arrested development equations in the polynomial logistic arrested development theoretical account. are population arrested development coefficients that are to be estimated from the informations. Their estimations are represented by B ‘s. The represents the unknown parametric quantities, while the B ‘s are their estimations. These equations are additive in the logits of p. However, in footings of the chances, they are nonlinear. The corresponding nonlinear equations are Since =1 because all of its arrested development coefficients are zero. Frequently, all of these theoretical accounts referred to as logistic arrested development theoretical accounts. However, when the independent variables are coded as ANOVA type theoretical accounts, they are sometimes called logit theoretical accounts. can be interpreted as that This shows that the concluding value is the merchandise of its single footings.3.7.1 Solving the Likelihood Equation:To better notation, allow The likeliness for a sample of N observations is so given by where is one if the observation is in group g and zero otherwise. Using the fact that =1, the likeliness, L, is given by Maximal likeliness estimations of are found by happening those values that maximize this log likeliness equation. This is accomplished by ciphering the partial derived functions and so equates them to zero. The ensuing likeliness equations are For g = 1, 2, aˆÂ ¦ , G and k = 1, 2, aˆÂ ¦ , p. Actually, since all coefficients are zero for g=1, the scope of g is from 2 to G. Because of the nonlinear nature of the parametric quantities, there is no closed-form solution to these equations and they must be solved iteratively. The Newton-Raphson method as described in Albert and Harris ( 1987 ) is used to work out these equations. This method makes usage of the information matrix, , which is formed from the 2nd partial derived function. The elements of the information matrix are given by The information matrix is used because the asymptotic covariance matrix is equal to the opposite of the information matrix, i.e. This covariance matrix is used in the computation of assurance intervals for the arrested development coefficients, odds ratios, and predicted chances.3.7.2 Interpretation of Regression Coefficients:The reading of the estimated arrested development coefficients is non easy as compared to that in multiple arrested development. In polynomial logistic arrested development, non merely is the relationship between X and Y nonlinear, but besides, if the dependant variable has more than two alone values, there are several arrested development equations. See the simple instance of a binary response variable, Y, and one explanatory variable, X. Assume that Y is coded so it takes on the values 0 and 1. In this instance, the logistic arrested development equation is Now consider impact of a unit addition in X. The logistic arrested development equation becomes We can insulate the incline by taking the difference between these two equations. We have That is, is the log of the odds at X+1 and X. Removing the logarithm by exponentiating both sides gives The arrested development coefficient is interpreted as the log of the odds ratio comparing the odds after a one unit addition in X to the original odds. Note that, unlike the multiple arrested developments, the reading of depends on the peculiar value of X since the chance values, the P ‘s, will change for different X.3.7.3 Binary Independent Variable:When Ten can take on merely two values, say 0 and 1, the above reading becomes even simpler. Since there are merely two possible values of X, there is a alone reading for given by the log of the odds ratio. In mathematical term, the significance of is so To wholly understand, we must take the logarithm of the odds ratio. It is hard to believe in footings of logarithms. However, we can retrieve that the log of one is zero. So a positive value of indicates that the odds of the numerator are big while a negative value indicates that the odds of the denominator are larger. It is probability easiest to believe in footings of instead than a, because is the odds ratio while is the log of the odds ratio.3.7.4 Multiple Independent Variables:When there are multiple independent variables, the reading of each arrested development coefficient more hard, particularly if interaction footings are included in the theoretical account. In general nevertheless, the arrested development coefficient is interpreted the same as above, except that the caution ‘holding all other independent variables changeless ‘ must be added. That is, can the values of this independent variable be increased by one without altering any of the other variables. If it can, so the reading is as earlier. If non, so some type of conditional statement must be added that histories for the values of the other variables.3.7.5 Polynomial Dependent Variable:When the dependant variable has more than two values, there will be more than one arrested development equation. Infect, the figure of arrested development equation is equal to one less than the figure of categories in dependent variables. This makes reading more hard because there is several arrested development coefficients associated with each independent variable. In this instance, attention must be taken to understand what each arrested development equation is anticipation. Once this is understood, reading of each of the k-1 arrested development coefficients for each variable can continue as above. For illustration, dependant variable has three classs A, B and C. Two arrested development equations will be generated matching to any two of these index variables. The value that is non used is called the mention class value. As in this instance C is taken as mention class, the arrested development equations would be The two coefficients for in these equations, , give the alteration in the log odds of A versus C and B versus C for a one unit alteration in, severally.3.7.6 Premises:On logistic arrested development the existent limitation is that the result should be distinct. One-dimensionality in the logit i.e. the logistic arrested development equation should be additive related with the logit signifier of the response variable. No outliers Independence of mistakes. No Multicollinearity.3.8 Categorization Trees:To foretell the rank of each category or object in instance of categorical response variable on the footing of one or more forecaster variables categorization trees are used. The flexibleness ofA categorization trees makes them a really dramatic analysis choice, but it can non be said that their usage is suggested to the skip of more traditional techniques. The traditional methods should be preferred, in fact, when the theoretical and distributional premises of these methods are fulfilled. But as an option, or as a technique of last option when traditional methods fail, A categorization treesA are, in the sentiment of many research workers, unsurpassed.The survey and usage ofA categorization treesA are non prevailing in the Fieldss of chance and statistical theoretical account sensing ( Ripley, 1996 ) , butA categorization treesA are by and large used in applied Fieldss as in medical specialty for diagnosing, computing machine scientific discipline to measure informations constructions, vegetation for categorization, and in psychological science for doing determination theory.A Classification trees thirstily provide themselves to being displayed diagrammatically, functioning to do them easy to construe. Several tree turning algorithms are available. In this survey three algorithms are used CART ( Classification and Regression Tree ) , CHAID ( Chi-Square Automatic Interaction Detection ) , and QUEST ( Quick Unbiased Efficient Statistical Tree ) .3.9 CHAID Algorithm:The CHAID ( Chi-Square Automatic Interaction Detection ) algorithm is originally proposed by Kass ( 1980 ) . CHAID algorithm allows multiple splits of a node. This algorithm merely accepts nominal or ordinal categorical forecasters. When forecasters are uninterrupted, they are transformed into ordinal forecasters before utilizing this algorithm It consists of three stairss: meeting, splitting and fillet. A tree is grown by repeatedly utilizing these three stairss on each node get downing organize the root node.3.9.1. Merging:For each explanatory variable Ten, unify non-significant classs. If X is used to divide the node, each concluding class of X will ensue in one kid node. Adjusted p-value is besides calculated in the confluent measure and this P value is to be used in the measure of splitting. If there is merely one class in X, so halt the process and set the adjusted p-value to be 1. If X has 2 classs, the adjusted p-value is computed for the merged classs by using Bonferroni accommodations. Otherwise, happen the sensible brace of classs of X ( a sensible brace of classs for ordinal forecaster is two next classs, and for nominal forecaster is any two classs ) that is least significantly different ( i.e. more similar ) . The most kindred brace is the brace whose trial statistic gives the highest p-value with regard to the response variable Y. For the brace holding the highest p-value, look into if its p-value is larger than significance-level. If it is larger than significance degree, this brace is merged into a individual compound class. Then a new set of classs of that explanatory variable is formed. If the freshly created compound class consists of three or more original classs, so happen the best binary split within the compound class for which p-value is the smallest. Make this binary split if its p-value is non greater than significance degree. The adjusted p-value is computed for the merged classs by using Bonferroni accommodation. Any class holding excessively few observations is merged with the most likewise other class as measured by the largest of the p-value. The adjusted p-value is computed for the merged classs by using Bonferroni accommodation.3.9.2. Splitting:The best split for each explanatory variable is found in the measure of unifying. The rending measure selects which predictor to be used to outdo split the node. Choice is accomplished by comparing the adjusted p-value associated with each forecaster. The adjusted p-value is obtained in the confluent measure. Choose the independent variable that has minimum adjusted p-value ( i.e. most important ) . If this adjusted p-value is less than or equal to a user-specified alpha-level, split the node utilizing this forecaster. Else, do non divide and the node is considered as a terminal node.3.9.3. Fillet:The stopping measure cheques if the tree turning procedure should be stopped harmonizing to the following fillet regulations. If a node becomes pure ; that is, all instances in a node have indistinguishable values of the dependant variable, the node will non be split. If all instances in a node have indistinguishable values for each forecaster, the node will non be split. If the current tree deepness reaches the user specified maximal tree deepness bound value, the tree turning procedure will halt. If the size of a node is less than the user-specified minimal node size value, the node will non be split. If the split of a node consequences in a kid node whose node size is less than the user-specified minimal kid node size value, child nodes that have excessively few instances ( as compared with this lower limit ) will unify with the most similar kid node as measured by the largest of the p-values. However, if the ensuing figure of child nodes is 1, the node will non be split.3.9.4 P-Value Calculation in CHAID:Calculations of ( unadjusted ) p-values in the above algorithms depend on the type of dependent variable. The confluent measure of CHAID sometimes needs the p-value for a brace of X classs, and sometimes needs the p-value for all the classs of X. When the p-value for a brace of X classs is needed, merely portion of informations in the current node is relevant. Let D denote the relevant information. Suppose in D, X has I classs and Y ( if Y is categorical ) has J classs. The p-value computation utilizing informations in D is given below. If the dependant variable Y is nominal categorical, the void hypothesis of independency of X and Y is tested. To execute the trial, a eventuality ( or count ) tabular array is formed utilizing categories of Y as columns and classs of the forecaster X as rows. The expected cell frequences under the void hypothesis are estimated. The ascertained and the expected cell frequences are used to cipher the Pearson chi-squared statistic or to cipher the likeliness ratio statistic. The p-value is computed based on either one of these two statistics. The Pearson ‘s Chi-square statistic and likeliness ratio statistic are, severally, Where is the ascertained cell frequence and is the estimated expected cell frequence, is the amount of ith row, is the amount of jth column and is the expansive sum. The corresponding p-value is given by for Pearson ‘s Chi-square trial or for likeliness ratio trial, where follows a chi-squared distribution with d.f. ( J-1 ) ( I-1 ) .3.9.5 Bonferroni Adjustments:The adjusted p-value is calculated as the p-value times a Bonferroni multiplier. The Bonferroni multiplier adjusts for multiple trials. Suppose that a forecaster variable originally has I classs, and it is reduced to r classs after the confluent stairss. The Bonferroni multiplier B is the figure of possible ways that I classs can be merged into R classs. For r=I, B=1. For use the undermentioned equation.3.10 QUEST Algorithm:QUEST is proposed by Loh and Shih ( 1997 ) as a Quick, Unbiased, Efficient, Statistical Tree. It is a tree-structured categorization algorithm that yields a binary determination tree. A comparing survey of QUEST and other algorithms was conducted by Lim et Al ( 2000 ) . The QUEST tree turning procedure consists of the choice of a split forecaster, choice of a split point for the selected forecaster, and halting. In QUEST algorithm, univariate splits are considered.3.10.1 Choice of a Split Forecaster:For each uninterrupted forecaster X, execute an ANOVA F trial that trials if all the different categories of the dependant variable Y have the same mean of X, and cipher the p-value harmonizing to the F statistics. For each categorical forecaster, execute a Pearson ‘s chi-square trial of Y and X ‘s independency, and cipher the p-value harmonizing to the chi-square statistics. Find the forecaster with the smallest p-value and denote it X* . If this smallest p-value is less than I ± / M, where I ± ( 0,1 ) is a degree of significance and M is the entire figure of forecaster variables, forecaster X* is selected as the split forecaster for the node. If non, travel to 4. For each uninterrupted forecaster X, compute a Levene ‘s F statistic based on the absolute divergence of Ten from its category mean to prove if the discrepancies of X for different categories of Y are the same, and cipher the p-value for the trial. Find the forecaster with the smallest p-value and denote it as X** . If this smallest p-value is less than I ±/ ( M + M1 ) , where M1 is the figure of uninterrupted forecasters, X** is selected as the split forecaster for the node. Otherwise, this node is non split.3.10.1.1 Pearson ‘s Chi-Square Trial:Suppose, for node T, there are Classs of dependent variable Yttrium. The Pearson ‘s Chi-Square statistic for a categorical forecaster Ten with classs is given by3.10.2 Choice of the Split Point:At a node, suppose that a forecaster variable Ten has been selected for dividing. The following measure is to make up one's mind the split point. If X is a uninterrupted forecaster variable, a split point vitamin D in the split Xa†°Ã‚ ¤d is to be determined. If X is a nominal categorical forecaster variable, a subset K of the set of all values taken by X in the split XK is to be determined. The algorithm is as follows. If the selected forecaster variable Ten is nominal and with more than two classs ( if X is binary, the split point is clear ) , QUEST foremost transforms it into a uninterrupted variable ( name it I? ) by delegating the largest discriminant co-ordinates to classs of the forecaster. QUEST so applies the split point choice algorithm for uninterrupted forecaster on I? to find the split point.3.10.2.1 Transformation of a Categorical Predictor into a Continuous Forecaster:Let X be a nominal categorical forecaster taking values in the set Transform X into a uninterrupted variable such that the ratio of between-class to within-class amount of squares of is maximized ( the categories here refer to the categories of dependent variable ) . The inside informations are as follows. Transform each value ten of X into an I dimensional silent person vector, where Calculate the overall and category J mean of V. where N is a specific instance in the whole sample, frequence weight associated with instance N, is the entire figure of instances and is the entire figure of instances in category J. Calculate the undermentioned IA-I matrices. Perform individual value decomposition on T to obtain where Q is an IA-I extraneous matrix, such that Let where if 0 otherwise. Perform individual value decomposition on to obtain its eigenvector which is associated with its largest characteristic root of a square matrix. The largest discriminant co-ordinate of V is the projection3.10.3 Fillet:The stopping measure cheques if the tree turning procedure should be stopped harmonizing to the following fillet regulations. If a node becomes pure ; that is, all instances belong to the same dependant variable category at the node, the node will non be split. If all instances in a node have indistinguishable values for each forecaster, the node will non be split. If the current tree deepness reaches the user-specified maximal tree deepness bound value, the tree turning procedure will halt. If the size of a node is less than the user-specified minimal node size value, the node will non be split. If the split of a node consequences in a kid node whose node size is less than the user-specified minimal kid node size value, the node will non be split.3.11 CART Algorithm:Categorization and Regression Tree ( C & A ; RT ) or ( CART ) is given by Breiman et Al ( 1984 ) . CART is a binary determination tree that is constructed by dividing a node into two kid nodes repeatedly, get downing with the root node that contains the whole acquisition sample. The procedure of ciphering categorization and arrested development trees can be involved four basic stairss: Specification of Criteria for Predictive Accuracy Split Selection Stoping Right Size of the Tree A3.11.1 Specification of Criteria for Predictive Accuracy:The categorization and arrested development trees ( C & A ; RT ) algorithms are normally aimed at accomplishing the greatest possible prognostic truth. The anticipation with the least cost is defined as most precise anticipation. The construct of costs was developed to generalise, to a wider scope of anticipation state of affairss, the idea that the best anticipation has the minimal misclassification rate. In the bulk of applications, the cost is measured in the signifier of proportion of misclassified instances, or discrepancy. In this context, it follows, hence, that a anticipation would be considered best if it has the lowest misclassification rate or the smallest discrepancy. The demand of minimising costs arises when some of the anticipations that fail are more catastrophic than others, or the failed anticipations occur more frequently than others.3.11.1.1 Priors:In the instance of a qualitative res ponse ( categorization job ) , costs are minimized in order to minimise the proportion of misclassification when priors are relative to the size of the category and when for every category costs of misclassification are taken to be equal. The anterior chances those are used in minimising the costs of misclassification can greatly act upon the categorization of objects. Therefore, attention has to be taken for utilizing the priors. Harmonizing to general construct, to set the weight of misclassification for each class the comparative size of the priors should be used. However, no priors are required when one is constructing a arrested development tree.3.11.1.2 Misclassification Costss:Sometimes more accurate categorization of the response is required for a few categories than others for grounds non related to the comparative category sizes. If the decisive factor for prognostic truth is Misclassification costs, so minimising costs would amount to minimising the proportion of misclassification at the clip priors are taken relative to the size of categories and costs of misclassification are taken to be the same for every category. A3.11.2 Split Choice:The following cardinal measure in categorization and arrested develop ment trees ( CART ) is the choice of splits on the footing of explanatory variables, used to foretell rank in instance of the categorical response variables, or for the anticipation uninterrupted response variable. In general footings, the plan will happen at each node the split that will bring forth the greatest betterment in prognostic truth. This is normally measured with some type of node dross step, which gives an indicant of the homogeneousness of instances in the terminal nodes. If every instance in each terminal node illustrate equal values, so node dross is smallest, homogeneousness is maximum, and anticipation is ideal ( at least for the instances those were used in the computations ; prognostic cogency for new instances is of class a different affair ) . In simple words it can be said that Necessitate a step of dross of a node to assist make up one's mind on how to divide a node, or which node to divide The step should be at a upper limit when a node is every bit divided amongst all categories The dross should be zero if the node is all one category3.11.2.1 Measures of Impurity:There are many steps of dross but following are the good known steps. Misclassification Rate Information, or Information Gini Index In pattern the misclassification rate is non used because state of affairss can happen where no split improves the misclassification rate and besides the misclassification rate can be equal when one option is clearly better for the following measure.3.11.2.2 Measure of Impurity of a Node:Achieves its upper limit at ( , ,aˆÂ ¦ , ) = ( , ,aˆÂ ¦ , ) Achieves its lower limit ( normally zero ) when one = 1, for some I, and the remainder are zero. ( pure node ) Symmetrical map of ( , ,aˆÂ ¦ , )Gini index:I ( T ) = = 1 –Information:3.11.2.3 To Make a Split at a Node:See each variable, ,aˆÂ ¦ , Find the split for that gives the greatest decrease in Gini index for dross i.e. maximise ( 1 – ) – make this for j=1,2, aˆÂ ¦ , P Use the variables that gives the best split, If cost of misclassification are unequal, CART chooses a split to obtain the biggest decrease in I ( T ) = C ( one | J ) = [ C ( one | J ) + C ( j | I ) ] priors can be incorporated into the costs )3.11.3 Fillet:In chief, splitting could go on until all instances are absolutely classified or predicted. However, this would n't do much sense since one would probably stop up with a tree construction that is as complex and â€Å" boring † as the original informations file ( with many nodes perchance incorporating individual observations ) , and that would most likely non be really utile or accurate for foretelling new observations. What is required is some sensible fillet regulation. Two methods can be used to maintain a cheque on the splitting procedure ; viz. Minimum N and Fraction of objects.3.11.3.1 Minimal N:To make up one's mind about the fillet of the splits, splitting is permitted to go on until all the terminal nodes are pure or they are more than a specified figure of objects in the terminal node.3.11.3.2 Fraction of Objects:Another manner to make up one's mind about the fillet of the spli ts, splitting is permitted to go on until all the terminal nodes are pure or there are a specified smallest fraction of the size of one ore more classs in the response variable. For categorization jobs, if the priors are tantamount and category sizes are same as good, so we will halt splitting when all terminal nodes those have more than one class, have no more instances than the defined fraction of the size of class for one or more classs. On the other manus, if the priors which are used in the analysis are non equal, one would halt splitting when all terminal nodes for which two or more categories have no more instances than defined fraction for one or more categories ( Loh and Vanichestakul, 1988 ) .3.11.4 Right Size of the Tree:The majority of a tree in the C & A ; RT ( categorization and arrested development trees ) analysis is an of import affair, since an unreasonably big tree makes the reading of consequences more complicated. Some generalisations can be presented about what constitutes the accurate size of the tree. It should be adequately complex to depict for the acknowledged facts, but it should be every bit easy as possible. It should use inform ation that increases prognostic truth and pay no attending to information that does non. It should demo the manner to the larger apprehension of the phenomena. One attack is to turn the tree up to the right size, where the size is specify by the user, based on the information from anterior research, analytical information from earlier analyses, or even perceptual experience. The other attack is to utilize a set of well-known, structured processs introduced by Breiman et Al. ( 1984 ) for the choice of right size of the tree. These processs are non perfect, as Breiman et Al. ( 1984 ) thirstily acknowledge, but at least they take subjective sentiment out of the procedure to choose the right-sized tree. A There are some methods to halt the splitting.3.11.4.1 Test Sample Cross-Validation:The most preferable sort of cross-validation is the trial sample cross-validation. In this kind of cross-validation, the tree is constructed from the larning sample, and trial sample is used to look into the prognostic truth of this tree. If test sample costs go beyond the costs for the acquisition sample, so this is an indicant of hapless cross-validation. In this instance, some other sized tree may cross-validate healthier. The trial samples and larning samples can be made by taking two independent informations sets, if a larger learning sample is gettable, by reserving a randomly chosen proportion ( say one 3rd or one half ) of the instances for utilizing as the trial sample. A Split the N units in the preparation sample into V- groups of â€Å" equal † size. ( V=10 ) Construct a big tree and prune for each set of V-1 groups. Suppose group V is held out and a big tree is built from the combined informations in the other V-1 groups. Find the â€Å" best † subtree for sorting the instances in group V. Run each instance in group V down the tree and calculate the figure that are misclassified. R ( T ) = R ( T ) + Number of nodes in tree T Complexity parametric quantity Number misclassified With tree T Find the â€Å" weakest † node and snip off all subdivisions formed by dividing at that node. ( examine each non terminal node ) I ) Check each brace of terminal nodes and prune if 13S 3 F Number misclassified at node T = 3 7 S 3 F 6 S 0 F=0 = 3 13S 3 F so do a terminal node. two ) Find the following â€Å" weakest † node. For the t-th node compute R ( T ) = R ( T ) + Number of nodes at or below node T Number misclassified If all subdivisions from node T are kept R ( T ) = = R ( T ) should snip if R ( T ) R ( T ) this occurs when at each non terminal node compute the smallest value of such that the node with the smallest such is the weakest node and all subdivisions below it should be pruned off. It so becomes a terminal node. Produce a sequence of trees this is done individually for V= 1,2, aˆÂ ¦ , V.3.11.4.2 V-fold Cross-Validation:The 2nd type of cross-validation is V-fold cross-validation. This type of cross-validation is valuable when trial sample is non available and the acquisition sample is really little that test sample can non be taken from it. The figure of random bomber samples are determined by the user specified value ( called ‘v ‘ value ) for V-fold cross proof. These sub samples are made from the acquisition samples and they should be about equal in size. A tree of the specified size is calculated ‘v ‘ A times, each clip go forthing out one of the bomber samples from the calculations, and utilizing that sub sample as a trial sample for cross-validation, with the purpose that each bomber sample is considered ( 5 – 1 ) times within the learning sample and merely one time as the trial sample. The cross proof costs, calculated for all ‘v ‘ trial samples, are averaged to show the v-fold estimation of the cross proof costs.
