Carbon Dioxide Poisoning Causes and Treatment

Carbon Dioxide Poisoning Causes and Treatment You are exposed to carbon dioxide every day in the air you breathe and in household products, so you might be concerned about carbon dioxide poisoning. Heres the truth about carbon dioxide poisoning and whether its something you need to worry about. Can Carbon Dioxide Poison You? At ordinary levels, carbon dioxide or CO2 is non-toxic. It is a normal component of air and so safe it is added to beverages to carbonate them. When you use baking soda or baking powder, you are purposely introducing carbon dioxide bubbles into your food to make it rise. Carbon dioxide is as safe a chemical as any youll ever encounter. Then Why the Concern Over Carbon Dioxide Poisoning? First, its easy to confuse carbon dioxide, CO2, with carbon monoxide, CO. Carbon monoxide is a product of combustion, among other things, and is extremely toxic. The two chemicals are not the same, but because they both have carbon and oxygen in them and sound similar, some people get confused. Yet, carbon dioxide poisoning is a real concern. It is possible to suffer anoxia or asphyxiation from breathing carbon dioxide, because increased levels of carbon dioxide may be related to decreased concentration of oxygen, which you need in order to live. Another potential concern is dry ice, which is the solid form of carbon dioxide. Dry ice generally is not toxic, but it is extremely cold, so if you touch it you risk getting frostbite. Dry ice sublimates into carbon dioxide gas. The cold carbon dioxide gas is heavier than the surrounding air, so the concentration of carbon dioxide near the floor may be high enough to displace oxygen, potentially posing a danger to pets or small children. Dry ice does not pose a significant hazard when it is used in a well-ventilated area. Carbon Dioxide Intoxication and Carbon Dioxide Poisoning As the concentration of carbon dioxide increases, people start to experience carbon dioxide intoxication, which may progress to carbon dioxide poisoning and sometimes death. Elevated blood and tissue levels of carbon dioxide are termed hypercapnia and hypercarbia. Carbon Dioxide Poisoning Causes There are several causes of carbon dioxide poisoning and intoxication. It may result from hypoventilation, which in turn may be caused by not breathing often or deeply enough, rebreathing exhaled air (e.g., from a blanket over the head or sleeping in a tent), or breathing in an enclosed space (e.g., a mine, a closet, a shed). Scuba divers are at risk of carbon dioxide intoxication and poisoning, usually from poor air filtration, not breathing at the normal rate, or simply from having a harder time breathing. Breathing the air near volcanoes or their vents may cause hypercapnia. Sometimes carbon dioxide levels become imbalanced when a person is unconscious. Carbon dioxide poisoning can occur in space craft and submarines when scrubbers arent functioning properly. Carbon Dioxide Poisoning Treatment Treatment of carbon dioxide intoxication or carbon dioxide poisoning involves getting carbon dioxide levels back to normal in the patients bloodstream and tissues. A person suffering from mild carbon dioxide intoxication typically can recover simply by breathing normal air. However, it is important to communicate a suspicion of carbon dioxide intoxication in case the symptoms worsen so that proper medical treatment may be administered. If multiple or serious symptoms are seen, call for emergency medical help. The best treatment is prevention and education so that conditions of high CO2 levels are avoided and so you know what to watch for if you suspect the levels may be too high. Symptoms of Carbon Dioxide Intoxication and Poisoning Deeper breathing Twitching of muscles Increased blood pressure Headache Increased pulse rate Loss of judgment Labored breathing Unconsciousness (occurs in under a minute when CO2 concentration rises about 10%) Death Reference EIGA (European Industrial Gases Association), Carbon Dioxide Physiological Hazards - Not Just an Asphyxiant, retrieved 01/09/2012. Key Points Carbon dioxide poisoning results in a condition called hypercapnia or hypercarbia.Carbon dioxide intoxication and poisoning can elevate pulse rate and blood pressure, produce a headache, and result in poor judgement. It can result in unconsciousness and death.There are multiple causes of carbon dioxide poisoning. Lack of air circulation, in particular, can be dangerous because breathing removes oxygen from the air and adds to its carbon dioxide content.While carbon dioxide can be toxic, it is a normal component of air. The body actually uses carbon dioxide to maintain proper pH levels and to synthesize fatty acids.

Heart of Darkness Essay Example | Topics and Well Written Essays - 1000 words - 1

Heart of Darkness - Essay Example He says: He has to live in the midst of the incomprehensible, which is also detestable. And it has a fascination, too, that goes to work upon him. The fascination of the abomination—you know. Imagine the growing regrets, the longing to escape, the powerless disgust, the surrender, the hate. This quote serves as pre-emptive explanation for why Marlow could not deny the power Kurtz held over other humans, despite his barbarity. Marlow then goes on to establish his love of reason and things that are real. In describing the appearance of several natives along the shore, Marlow relates: It was something natural, that had its reason, that had a meaning. Now and then a boat from the shore gave one a momentary contact with reality. It was paddled by black fellows. You could see from afar the white of their eyeballs glistening. They shouted, sang; their bodies streamed with perspiration; they had faces like grotesque masks—these chaps; but they had bone, muscle, a wild vitality, an intense energy of movement, that was as natural and true as the surf along their coast. They wanted no excuse for being there. They were a great comfort to look at. For a time I would feel I belonged still to a world of straightforward facts; but the feeling would not last long. Something would turn up to scare it away. The love of the real and tangible, of work, effort and improvement are themes Conrad returns to again and again through Marlow. The character Marlow likes belonging to a world where things really are as they appear. He does not like intrigues, rumors, or deviousness. He likes steel plates and rivets, honest emotion and truthfulness. The honest work, the seat and effort of the natives was solace to Marlow as he was surrounded by plotting privateers. Marlow’s distain for intrigues and falsehood is embodied by the station manager. Of him, Marlow says: He was obeyed, yet he inspired neither love nor fear, nor even respect. He inspired uneasiness. That was it! Uneasiness. Not a definite mistrust—just uneasiness—nothing more. This character is so loathsome to Marlow that he doesn’t even inspire a single honest emotion. The manager is held in contempt in every way by Marlow. The only possible complement that can be said of the man is that he survives, but even that is not attributed to any sort of effort on his part. It is simply a result of his constitution. In fact, the whole of the station is repugnant to Marlow. He states: There was an air of plotting about that station, but nothing came of it, of course. It was as unreal as everything else—as the philanthropic pretense of the whole concern, as their talk, as their government, as their show of work. The only real feeling was a desire to get appointed to a trading-post where ivory was to be had, so that they could earn percentages. The station was a mash of plots and intrigues that were so contrived as to never even come to any account. The inhabitants of the station held titles but acted in no manner to accomplish the work associated with the title given. Work, and the importance of it is mentioned by Marlow on several occasions in telling his story. This is important because it is a vital link between himself and Kurtz. Marlow reveals his feelings towards work when he stated: I don't like work—no man does—but I like what is in the work,—the chance to find yourself. Your own reality—

Correlation between Safety and Judgement (Pychology Static Research) Essay

Correlation between Safety and Judgement (Pychology Static Research) - Essay Example However, as the safety of a person depends on interpersonal skills as well as communication skills, the positive attitude also helps in gaining self confidence as well as keeping away from disasters in life. The usage and application of interpersonal skills depend on the surroundings and the ability of the individual to use his communication skills as per the needs. In this paper, 41 people of age groups 18 and 21 are analyzed according to the above mentioned aspects. The individuals selected are the people aged between 18 and 21 years, having mean age as 20 years. Hence, Mean age =20. Range = 3. Majority of the participants are Caucasian and the families belong to middle class. Participants visited the psychologist's lab all at a once, when they are given a test regarding their decision making and judgment. After that they met psychologist once in a month and out of 41 three of the participants visited once in three months for the first one year. Hence, for 38 participants the yearly visits were 12 and for three of them they were 4 each. Consequently, when the values of yearly visits are calculated, there are 38 values of each 12 and 3 values of each 4. The standard deviation for the above values is 11.4 and is nearer to the majority of the values in the visits data and hence the researchers considered the results. In the second year for the first six months, all the participants are asked to visit once in two months and all the participants fol lowed the instruction. In the next six months of the second year, they were asked to visit once in three months and at the last visit, the consequences of their judgment have been compared. Method In the research the individuals are given two consequences and are asked for answers. The first one is about an uncomfortable situation that demands a judgment to come out of it safely and the second one is about a normal situation that talks about the future situation. The participants responded according to their confidence level and amount of attribution. Researchers classified the 41 participants into groups according to their confidence levels and amount of attribution. As amount of attribution depended on confidence level, participants are divided into three groups basically having high confidence level as well as attribution (A), the high level of self control with resourcefulness (B), the participants having less confidence as well as self control (C). In group A, there are 12 participants, 13 participants in group B and 16 participants in group C. The division of the participants into three groups has been done based on the conversations during the visits in the first year. Moreover, researchers found that the resourcefulness of participants while taking a decision. While considering the resourcefulness, the researchers graded the decisions of the participants according to different situations that come over in the course of one's life according to the individual's community and profession. The safety and judgment results are as following according to the confidence, attribution levels of the groups. It is clear from the following graph, that the self control group that have high resourcefulness has shown greater safety for their judgments in the course of time.

The Human Eye in Space :: essays research papers

Human visual hardware is a result of a billion years of evolution within the earths atmosphere where light is scattered by molecules of air, moisture, particular matter etc. However as we ascend into our atmosphere with decrease density, light distribution is changed resulting in our visual hardware receiving visual data in different format. Some Aspects to Consider: 1. Visual acuity is the degree to which the details and contours of objects are perceived. Visual acuity is usually defined in terms of minimum separable.Large variety of factors influence this complex phenomenon which includes : # Optical factors- state of the image forming mechanisms of the eye. # Retinal factors such as the state of the cones. # Stimulus factors such as illumination, brightness of the stimulus, contrast between the stimulus and background, length of time exposed to the stimulus. * Minimum separable: shortest distance by which two lines can be separated and still be perceived as two lines. "During the day, the earth has a predominantly bluish cast..... I could detect individual houses and streets in the low humidity and cloudless areas such as the Himalaya mountain area.... I saw a steam locomotive by seeing the smoke first..... I also saw the wake of a boat on a large river in the Burma-India area... and a bright orange light from the British oil refinery to the south of the city (Perth,Australia.)" The above observation was made by Gordon Cooper in Faith 7 [1963] and which generated much skepticism in the light of the thesis by Muckler and Narvan "Visual Surveillance and Reconnaissance from space vehicles" in which they determined that a visual angle of ten minutes was the operational minimum, and that the minimum resolvable object length [M.R.O.L] at an altitude of 113 miles would be 1730 ft. This limitation of acuity was revised the next year to 0.5 seconds of arc for an extended contrasting line and 15 seconds of arc for minimum separation of two points sharply contrasting with the background. Orbiting at 237 miles in the skylab it was possible to see the entire east coast [Canada to Florida Keys] and resolve details of a 500 feet long bridge based on inference. Of Interest is the fact that even though the mechanical eye [camera systems] can resolve objects greater than fifty times better than the human eye, without the human ability to infer, interpretation of the data is meaningless. Conclusion: Visual acuity in space exceeds that of earth norm when objects with linear extension such as roads, airfields, wake of ships etc. 2. Stereoscopic vision: the perception of two images as one by means of fusing the impressions on both retinas. In space one has to deal with a poverty of reference points.

`Examine the role in the witches in “Macbeth” Essay

In Shakespearian England witches were said to be in league with the devil. Shakespearian audience believed that witches were always up to no good and people thought they were wicked and devious. Old, Single or widowed women (who often kept pets for a companion) were often blamed as being witches and their pets were kept as servants. In those times people blamed any unexplained happenings such as bad weather, gone off food, deadly diseases, deaths of livestock and even murders. Despite this people were still fascinated by witchcraft they went to see horrifying plays just like we in modern days go to the cinema to watch horror films. Shakespeare wrote a play about witches to please King James 1, he was on the throne at the time when the play was written. King James wrote a book about witchcraft called Demonology because he was fascinated about witchcraft. Shakespeare knew he would win the king over by making a play like this. The witches were only in 3 scenes in Macbeth but they influence the atmosphere across the whole play. In the opening scene the audience would be thrilled because the witches created a theatrical atmosphere. The atmosphere was very negative because there was terrible weather â€Å"thunder and lightning† this would make the scene very frightening because of the loud noises of the lightning. The witches speak in riddles this unnerves the audience by their chants and riddles for example†fair is foul and foul is fair hover through the fog and filthy air†. The audience would find Macbeth is daunting because of the eerie atmospheres of the scenes and the spooky witches. At the beginning of act 1 scene 3 the three witches are talking about the things they have done to other people. Shakespeare does this because he shows what the witches are capable of. â€Å"I will drain him dry as hay† the first witch said this because she wanted to show what she could do. The three witches meet Macbeth and Banquo â€Å"upon the heath†. Meanwhile the witches predict that Macbeth and Banquo’ sons will be kings in the future. They say two facts that Macbeth is going to be thane of Cawdor and thane of Glamis. The witches do not tell Banquo or Macbeth what to do. Macbeth thought that it’s because the witches predict he is going to be thane of Cawdor. â€Å"Do you not hope that your children shall be kings, when these that gave the thane of Cawdor to me promised no less to them?† This shows that Macbeth trusts the witches by everything they predicted and he thinks that the witches gave him the role of being the king. Macbeth doesn’t believe he is the thane of Cawdor at first but eventually he learns he is. Banquo was really frightened about what the witches claimed but Macbeth was really excited. â€Å"two truths are told as happy prologues to the swelling act of the imperial theme† this shows Macbeth like what the witches tell him particularly that he is going to be king however, he has mixed feelings. â€Å"Why do I yield to that suggestion whose horrid image doth unfix my hair and make my seated heart knock at my ribs (against the youth of nature)?† this shows Macbeths reaction changes. In act 2 scene 3 Shakespeare makes the atmosphere dark and terrifying. â€Å"There’s husbandry in heaven their candles are all out† the dark represents evil and negativity which could be seen as a warning of trouble to come (foreshadowing). Macbeth’s original fear is demonstrated in his hallucinations after his immoral act of murdering. Macbeth shows signs of possessions â€Å"me thought I heard a voice say sleep no more† He says I thought I heard voices†. Macbeth shows he feels guilty by saying â€Å"amen stuck in my throat† he says this to show how he felt and whether he was regretting of the crime he just commit. The witches powers were demonstrated by strange happenings for example â€Å"tis’ said they eat each other† this was said because horses started eating each other which was very unusual and peculiar. This information was in the play to horrify the audience. Act 4 scene 1 begins with the witches chanting this reminds me of a spell. The witches always use trochaic tetrameter the effect of that makes it sound like a chant. The ingredients have unpleasant things in common for example animal parts and poisons. The most horrible point in the spell was â€Å"finger of a birthstrangled babe, ditch deliver’d by a slab† this means a baby born in a ditch from a prostitute strangled at birth. The Shakespearian audience would be horrified at the contents of the charm. In act 4 scene 1 Shakespeare included the spell in the scene to portray real witches and to show they made wicked spells considered associated with evil. The rhythm used is called trochaic tetrameter the effect of it makes it sound like a chant; trochaic tetrameter is always 4 beats per line. The witches added body parts of a Christian, Shakespeare knew it would affect the scene because people in those times didn’t trust non Christians and thought they were up to no good. Macbeth believes when he goes back to see the witches that they will tell him what to do. The witches make three prophecies, the first one warns†beware Macduff: beware the thane of fife† Macbeth thought to himself when this was shown I don’t believe Macduff anyway. The second one warns â€Å"a bloody chid† â€Å"for none of women born shall harm Macbeth† Macbeth felt he was invincible and decides to get Macduff and his family killed anyway. The third prophecy warns â€Å"Macbeth shall never vanquish’d be until Great Birnam wood to high Dunsinare hill shall come against him† this was meant by Macbeth will never be defeated until great Birnam wood comes and lives in his castle. Macbeth felt very pleased and assertive. The witches realise that Macbeth is now evil through the words they use just before he comes in â€Å"By the pricking of my thumbs something wicked this way comes† Macbeth asks the witches if Banquo’s sons will be kings. The witches reply†seek to know no more† they try to tell the truth and are warning him he doesn’t want to know. Macbeth realises he is evil and under the witches spell we know this because he says â€Å"infect’d be to air where on they rides and damn’d all those that trust them!†. â€Å"Macduff was from his mothers womb untimely ripped† At that point Macbeth realises the witches were deceiving him all along. One of the main reasons that Shakespeare included the witches in the play was because they influence the theme of deception across the whole play. The witches introduce the theme of deception in the opening scene act 1 scene 1 where they say â€Å"fair is foul and foul is fair† this affects not only Macbeth but all the characters this is shown when lady Macbeth says â€Å"look like the innocent flower but be the serpent under it†. Later on Macbeth realises he has to be deceitful in order to succeed he says â€Å"false face must hide what the false heart doth know†. The witches talk in riddles when they say â€Å"Macbeth shall never vanquish’d be until Great Birnam to high dunsinare hill shall come against him† Macbeth misunderstands this he thought this was impossible that the forest will come to his castle but the soldiers cut down the trees and bring the forest to the castle Macbeth is dumbfounded. Shakespeare creates typical witches to scare the audience the type of witches that fly, induce nightmares and stop people from sleeping. The witches predict the future but Macbeth thinks they are telling him what to do he then shows demonic possessions â€Å"I had almost forgot the taste of fear† Macbeth showed lack of fear. Shakespearian audience would go to see Macbeth to get a thrill for entertainment just like we nowadays go to the cinema to watch a horror film. The witches create an atmosphere of evil throughout the whole play.

A. ADD. (1997, Par 06). Dayton Daily News. Retrieved from http://search. Prostitutes/ This article was published in the Dayton Daily News. The main focus of this article was the simple definition of what At tention deficit hyperactivity disorder is. It explained that it individuals with this disorder are unable to pay attention and are very impulsive. It states that children with this disorder often do not do well in school.No matter what their intelligence level is, they still will not do well in school. The article listed many symptoms that include having short attention spans, forgetful, do not meme to listen well, do not pay attention to details and individuals also fail to finish things they Start. This article listed many symptoms that I were not aware were part of it. At the same time many of the symptoms seem to describe many children in preschool and kindergarten age. Which it surprised me that the article stated that children need to be diagnosed before the age of 7.But I was glad to see that some of the symptoms have to create a real hardship in the lives before the individual can be diagnosed. This article was helpful in the sense that it was very simple and straight to the point. It loud be good to have as a reference in order to maybe talk to parents if problems become apparent with a child. B. Sorrows, K. F. (2009). ADD: urban teachers' knowledge, beliefs and classroom practice. (Order No. 3361083, University of Massachusetts Boston). Prosiest Dissertations and Theses, , 234-n/a. Retrieved from http://search. Prosiest. Mom/ deceive/305140059? Cacao anti=32521. (305140059). This article was written by Karen Sorrows in 2009. This article talked about the importance of teacher intervention with students that have ADD. These students were from the urban area where medical intervention is less likely to append. The article also discusses how a teacher may juggle the needs of students with ADD and the others students who do not have the disorder. It talks about the interrelationships between urban elementary school teachers use and effectiveness of research based interventions for ADD.The study showed teachers' knowledge of ADD and the support they recei ve from the school districts. This was a very useful article in the way that it showed that there are support groups and other teachers deal with students with ADD. It allows a community for a teacher to go to and get any idea and or help if they deed it. It helps put in perspective that there are many families and children that are affected by this disorder that are unable to seek medical help and it is up to the teacher to try to make the best of the situation for the children sake.

Journal of Abnormal Child Psychology, 41 901-17. Did:http://DXL. Did. Rover. MM 0802-013-9729-9 This article was written by several authors that included Dovish, Van, Wires, ND Primps. This article talks about the defects in the working memory that are common with ADD. In children that have ADD their working memory is what is affected the most. Both cognitive and motivational deficits are aberrant working memory performance.This is a good article in the sense that it helps individuals understand the inside working of the mind of a child who has ADD. It helps show the memory that it affects and controls. From the visual to the short term memory, there is more to ADD then we know. I found this article very interesting and it is very informative on the details of he workings of the brain of an individual with ADD. 5. Summarize the overall findings of your research including the summary, description, critique, and synthesis completed for each individual article. A.In the article that I read I found that there are fewer children that are affected with ADD than prior thought. It is said that only 5% of children are affected with ADD. It also gave me some insight on what some of the symptoms are. Even though some seem very extreme, the symptoms are very treatable. Most children with ADD are able to b ecome functioning parts of society once they become adults. It is said that all children no matter what their intelligence level maybe still have problems academically in one way or another. I also learned that many parents blame the school systems for their child's ADD problems.They blame the teachers for not being able to â€Å"teach† properly or looking for a way out of teaching their children. ADD is a genetic disorder that runs throughout the family. 6. Describe two applications this research and your deepened understanding of this educational psychology topic have to the following: a. Academic goals I. My research has really opened my eyes on how children with ADD feel and hat they may go through. It is a very sad and yet very challenging. Plan to try to keep up on all the information that I can in order to make sure that each student gets the best education possible.I know that some children with ADD can be difficult in the classroom and with other students, but it is my job as an educator to stay current with all that is happening and any new teaching techniques. Taking extra classes and helping parents as much as I can is always an option. I will also learn to distinguish the difference between a child acting out and a child who may have ADD b. Personal goals I. I know that what have researched will help in my future teaching career. I plan on teaching middle school history and children at that age can be very trying at times.I can only hope that the proper steps were taken in prior years through possible academic assessments and other symptoms to get children the medical help that they need in order to do well through the middle school years. Can only hope that if by chance I do encounter a child with ADD I have learned the proper tools in order to give the child the best education I can. C. Current role I. In my current role as a mother, wife and a full time employee I can see that I eave seen many individuals with many (but not all and not c onsecutively) symptoms of ADD and to be honest it can be very frustrating at times.

Free Essays on God’s Existence According To Anselm & Kant

God’s Existence According to Anselm & Kant Anselm’s ontological argument begins with the idea that God is something of which nothing greater can be conceived. He recognizes that some people say there is no God. However, while they may not believe in God, they understand that they are denying his existence. Therefore, God exists even to the nonbelievers understanding. Anselm also states that whatever is understood exists in the understanding. He also tells us that existing in reality is greater the existing only in the understanding. If existing in reality is greater, then God had better exist in reality, as well as in the understanding. Otherwise, we could conceive of something better, and God would no longer be the greatest conceivable being. Anselm’s argument is presented to the reader in an a priori form he structures it into four main premises and a single, final conclusion, making his argument hard to object against. The premises also do not rely on experience for their validation. Anselm’s argument turns anyone who says, â€Å"I don’t believe in God.† Into a bit of a fool, and it also makes this statement one of contradiction. The fool understands the definition of God but denies that God exists. An easier way to look at Anselm’s ontological argument is to become that fool, for a moment, and imagine that God exists in the understanding, solely. Now, given Anselm’s definition, this means that a being than which nothing greater can be conceived exists in the understanding, solely. This same being can be conceived to exist in reality. Even if we don’t believe that it is actually true, we can imagine a place where it is true. However, keeping in mind that it is greater for a thing to exist in reality than for it to exist in the understanding solely. We are almost forced to conclude that this God, which nothing greater can be imagined, can be conceived to be greater than it is. That does not make sense, so we ...

ESL Pronunciation Exercises - Short Vowels Consonants

ESL Pronunciation Exercises - Short Vowels Consonants The following series of pronunciation exercises combines words beginning with the same consonant sound followed by similar vowel sounds. Voiced and voiceless consonants are paired (b - voiced / p - voiceless, d - voiced / t - voiceless, etc.) to help students compare and contrast similar consonant formation. Pairing similar phonemes to improve pronunciation skills is also known as the use of minimal pairs. Minimal pairs change words by one phoneme so that the basic pronunciation pattern remains the same with one slight - minimal - difference. This allows students to really focus in on the slight difference in jaw, tongue, or lip placement needed to make the various phonemes. Repeat each line slowly, listen for the minor differences between the vowel and consonant sounds.Repeat each line three times. Each time repeat more quickly trying to keep the sounds distinct.Find a partner and listen to each other repeat the lines.Try to invent sentences using each sound at least once. For example: The big bat bet he could beat the others. - Dont worry too much about the sentence making much sense! ih - pronounced ih as in hit ee - pronounced ee as in see eh - pronounced eh as in let ae - pronounced ae as in cat big beat bet bat pig peep pet pat did deal death dad tip teeth tell tap gill gee! get gap kill keep kept cat sip see set sat zip zeal zeppelin zap ship sheet shelf shaft gin jeep jell jack chip cheek chess chat hit heat help hat Vowel Sounds eh - as in let, ih - as in hit, ee - as in see, and ae- as in catlong ah - as in car, short ah - as in gotlong uh - as in put, short uh - as in up, oo - as in through Diphthong Sounds ay - as in day, ai - as in skyou - as in home, ow - as in mouse, oi - as in boyieh(r) - as in near, ehi(r) - as in hair

What Is Neoliberalism In The United States Research Paper

What Is Neoliberalism In The United States - Research Paper Example Unlike in other countries such as the Western Europe and Japan, the United States has been very successful in terms of the use of neoliberal policies in this country. This explains why the United States is considered the leader of imperialist countries (Dumenil and Levy 9). In general, the concept of neoliberalism is based on the classical liberal economic practice that was widely used in the United States for many years way before the Great Depression took place in 1930s (Dumenil and Levy 1, 12). However, between the mid-1930s up to mid-1970s, the US government decided to implement the use of the â€Å"interventionist† approach rather than the typical classical liberalism (Kotz). When Ronald Reagan was elected as the President of the United States back in 1980, the US government started supporting the use the classical liberalism in making public policies which aims to limit labor power, deregulate industries and agriculture within and outside the United States (Harvey). The main purpose of this study is to discuss the significance of neoliberalism in North Atlantic states particularly in the case of the United States. As part of analyzing the impact of neoliberalism in the U.S., this study will first discuss what neoliberalism is all about followed by discussing how neoliberalism in the United States has affected the developments in â€Å"deregulation† and â€Å"privatization† of public companies. What is Neoliberalism? According to Dumenil and Levy (5), neoliberalism is the â€Å"new phase in the evolution of capitalism†. Basically, the word â€Å"neoliberalism† is commonly used as a general term for economic liberalization of public policies and advocates (Fish; Boas and Gans-Morse). Since we are already in the era of globalization, a lot of academic institutions have considered neoliberalism as a â€Å"central guiding principle of economic thought and management† (Harvey). However, the question remains as to what n eoliberalization really mean and why the United States has been very supportive of neoliberalism? As defined by Mirowski and Plehwe (13-14), neoliberalism is â€Å"the priority of the price mechanism, the free enterprise, the system of competition and a strong and impartial state†. It means that neoliberalism strongly believe in the idea that a society should never be considered as a product of natural development. Instead, people should continuously promote the importance of having a free society that is subject to a â€Å"free market economy† or an â€Å"unregulated capitalist system† (Harvey ; Kotz). In general, the neoliberals strongly believe that a free market competition could challenge each business entity to improve not only their knowledge in managing a business but also maximize the use of technology. By giving each person the freedom to choose, neoliberals explained that business people can support the increase in the country’s overall economi c performance. It means that the business people are expected to become more focused in finding ways on how they can effectively increase their production efficiency and output, progress in the use of machineries and information technology, and promote distributional justice in order to increase the annual U.S. economic growth. As a free country that practices free trading, Kotz explained that the U.S. government has a limited role in its economic development. In general, the neoliberals consider the presence of state intervention as an external factor that can trigger more problems on the part of the business sectors. The public policy under neoliberalism
