The Impact on America of Alexander Hamilton and Thomas Jefferson Essay
The Impact on America of Alexander Hamilton and Thomas Jefferson Thomas Jefferson and Alexander Hamilton were completely at odds in their vision on how America was to develop. Hamilton wanted to concentrate power in a centralized federal government with limited access and Jefferson wished to diffuse it among all the eligible freemen of the time. Alexander Hamilton feared anarchy and distrusted popular rule while Jefferson feared tyranny and thought in terms of liberty and freedom. Thomas Jefferson was an agrarian soul who favored popular rule. He placed his trust in the land and the people who farmed it and desired that America would remain a nation of farmers. He emphasized liberty, democracy, and social welfare and believed that the main purpose of government was to assure freedom of its individual citizens. He had a fear of tyranny and distrusted centralized power, especially from an aristocracy or a moneyed class. Thomas Jefferson favored the spread of power ranging from the federal level to state and local levels. Jefferson stated, ?I have never observed men?s honesty to increase with their riches.'; Alexander Hamilton, on the other side, distrusted popular rule and emphasized law, order, authority and property. Alexander Hamilton wanted to promote commerce and industry through a strong central government. He also would diversify American economic life by encouraging shipping and creating manufacturing by legislative directive. Hamilton also believed that a ...

Cover Girl Cosmetics Essay examples -- marketing business
Cover Girl Cosmetics Why Cover Girl is one of the most successful cosmetic organizations since the 1960ââ¬â¢s? Cover Girl cosmetics have been the top-seller since 1961 and are still going strong. It is hard, with all the advanced lines of make-up for one product to go as far as Cover girl has, so how does Cover Girl cosmetics do it? A lot of Cover Girlââ¬â¢s strong, on going successes are due to changing the look of the product, exceptional promotions which the public canââ¬â¢t look over, giving a cosmetic appeal to both older and younger aged women and most importantly by using near perfect women and teens to model their products. Although itââ¬â¢s wonderful that Cover Girl has been and still is so successful, it has put a dentation in todayââ¬â¢s society in what womenââ¬â¢s appearance should and shouldnââ¬â¢t be. Women and young adolescence are confused of what their appearance should be. Cover Girl has many famous models; one inparticular is the famous country singer Faith Hill. Faith is tall, skinny, and flawless. When women see models like her doing the advertising for Cover Girl, they automatically feel that they should look the same. Later in this paper I will go into semiotics which derives from the Greek word semeion meaning sign, it basically describes how people interpret different signs, such as models, and how these signs might effect oneââ¬â¢s life and self-esteem. Proctor & Gamble are the owners and starters of Cover Girl cosmetics. To keep up the success of Cover Girl they must keep on top of the advertising game to stay above the competitors. To do this they do many promotions, some include using famous singers, changing displays, giving away samples and one of the most important advertisement of all is the models Cover Girls incorporates in their ads. Cover Girls did one promotion with Target stores to promote their product. They used the famous group 98 Degrees to make a sweepstakes called, ââ¬Å"Fall in Love with 98 Degrees Sweepstakes.â⬠The grand prizewinner of this sweepstakes is an appearance in the new 98 Degrees music video. This advertising doesnââ¬â¢t just take place in the Target stores; it also takes place in Teen magazine, stickers on the new 98 Degrees CDs, a national radio campaign, and the national Teen People magazine. Because itââ¬â¢s teens that mainly listen to the music that 98 Degrees produces, itââ¬â¢s the teens that this particular promotion is focused on. I s... ...so very successful because of their unique forms of advertising and promotions. Contacting certain audiences which is their main target during different promotions is a wonderful way to go. Understanding advertising will better help you understand yourself and make you realize whom you really are and whom you will always be no matter how many cosmetics you buy.

Linguistics and Children Essay
This assignment will firstly explain the meaning of the following terms, communicative competence and metalinguistic awareness. Observations have shown that children do imitate older peers and adults when speaking as well as signs of creativity from an early age when developing language. Then the second section will evaluate the roles of creativity and imitation in regards to learning spoken English. This assignment will focus on the spoken English of young children. Part 1 Communicative competence ââ¬â Is a term that refers to the way in which a language user communicates efficiently and successfully depends upon their communicative competence. Linguist Noam Chomsky depicted a variation within the term ââ¬Ëlinguisticââ¬â¢ which he divided into to competence and performance. The term linguistic performance is associated with incorrectly and/or repeated ungrammatical delivered actual utterances of language in use. Linguistic competence refers to the knowledge of the language system which will enable the speaker to distinguish the utterances that are grammatical in the language from those that are not. (Chomsky, 1965 cited in Book3, pg 48) However linguist Hymes believed speakers need to attain distinctive skills in performance such as what is the socially appropriate turn of phrase to accomplish the desired effect as well as knowing when to speak. With regards to children as well as learning the construction and sounds of particular languages they are actually learning the discourse procedures of their communities. The term also incorporates word meaning, grammar and pronunciations well as applying language aptly, verbally, written and non- verbal cues such as body language. (Book3, pg 201) Metalinguistic awareness ââ¬â Is a term used to define an individualââ¬â¢s ability to reflect on the use of language in with regards to clarifying the transfer of linguistic skills and knowledge across languages. When a language userââ¬â¢s metalinguistic awareness develops they start to create new and refined use of metaphors such as the simile ââ¬Å"life is like a box of chocolates, you never know what youââ¬â¢re going to getâ⬠they also begin to realise that statements can have an implied meaning as well as a factual meaning. They may even start to identify sarcasm along with contrariness which connects with an individualââ¬â¢s capability of telling and /or understanding jokes, manipulating language (Kerper, 2009) Part 2 Children can acquire language as a result of imitation however it isnââ¬â¢t the initial method into language acquisition due to children demonstrating creative practice of language. (Book 3, pg 27) Infants produce a variety of sounds during the initial year of their life in addition to experimenting with vocal play. (Book 3, pg 8) The rate of development differs between each child, for example it is rare for a child to skip the babbling stage, which usually occurs at the average age of 11months, and another factor that assists speech development is physiological maturation. (Book 3, pg9) Benedict, 1979 cited in Book 3, pg19 researched development of vocabulary of a small group of children (8) during the course of six months. The findings demonstrated childrenââ¬â¢s ability to understand and create words between the ages of 10 months and on average 1 year 9 months. By the time the child is 11 months and 15 days they are usually attain a comprehension vocabulary of twenty words. The process of attaining words in production takes longer than it does in comprehension, comprehension can usually occurs 4 months before production. With regards to ââ¬Ëimitationââ¬â¢ the role of the caregiver (a term used for those individuals who spend the most time interacting with and looking after the child. ) (Book 3, pg 11) much research has been done in this area whereby the emphasis is on a pair in this case it involves the child and their main caregiver, this is also known as a term called a dyad. The findings from this research revealed that the person the child has most direct contact with impart the language surroundings that the child will model. Other linguistic modelling that adults provide is through caregiving schedules, for instances bathing and feeding, these routines provide occasions for conventional interactions concerning language. ââ¬ËPeek a booââ¬â¢ A customary game that is usually played between infant and caregiver and generally in Western cultures. (Book 3, pg14) As a rule the adult attempts to grasp the infantââ¬â¢s interest the concealing their eyes behind a hand or an object after which a type of discourse occurs, for example the adult might say ââ¬ËAre you ready? ââ¬ËThen the infantââ¬â¢s vocalisations or actions are indicated as a response. This sequence of question ââ¬âand ââ¬â reply is continued until the apprehension develops at this point the adult takes their hand away or removes the object and says ââ¬ËBoo! ââ¬â¢ (Book 3, pg 15) Trevarthen and Aitken , 2001 cited in Book 3, pg 15 believed this kind of game could be termed ââ¬Ëprotoconversationsââ¬â¢, because it is similar to a conversation. It requires turn ââ¬â taking, each personââ¬â¢s turn relies on the previous is input of the partner, therefore it is contingent, the partners understand the sequence disclose the same intention. Therefore this kind of interaction initiates ceremonial features of conversations before young children are able to speak but prompt passage to language. A universal observation made regarding the type of dialogue directed to children by adults is that the dialogue differs to that addressed to other adults. Consequently caregivers amend their dialogue for instance delivery slowed down, intonation is amplified and an elevated pitch may be used. Older children also adapt their dialogue for younger children comparable to adults, this is also evident that older children are emulating adults and implementing this technique to young children. (Book 3, pg15) this dialogue style is referred to as child directed speech (CDS). Clifton Pye, 1986 cited in Book 3, pg 16 observed a community in Central America called Quiche, they spoken one of the native Mayan languages. The results showed a difference in the way in which Quiche caregivers and Western caregivers adapt their dialogue for young children. Regardless of this cultural difference in caregiver ââ¬â child interaction, the children in the Quiche community were able to speak fluently in their native language. Shirley Brice Heathââ¬â¢s research 1983 cited in Book 3, pg 16 of black working-class English speaking community discovered that adults in this community didnââ¬â¢t usually use ââ¬Ëbaby talkââ¬â¢ when interacting with young children. The ways in which childrenââ¬â¢s grammar develop could also be due to imitation as well. Descriptive grammar is a term referring to how children organise and structure speech, it doesnââ¬â¢t link to the correct ââ¬ËEnglishââ¬â¢ people should use. Investigations into childrenââ¬â¢s grammar showed that a constant procedure is involved in the attainment of grammar. Crystal, 1995, cited in Book 3, pg 25 acknowledged seven stages ranging from formative years to adolescent. In the early stages of grammatical development children apply brief utterances of two to three words without any grammatical markers; children are usually aged between 18 months to 2 years. In the next stage of usually 3 years children start to add markers to words such as tense ( I played), plural (one cat, two cats). The second stage within Crystalââ¬â¢s paradigm is a term called telegraphic speech during this stage, children do not use grammatical markers instead they use verbs, temporal adverbs, adjectives and nouns. The crucial information is apparent because the details and trimmings are removed; this telegraphic quality is stated in childrenââ¬â¢s imitation of adultââ¬â¢s speech. Also during the second stage it has been noted that childrenââ¬â¢s speech will likely to be: a more water; baby drink; allgone sticky. However in this instance it is unlikely that children will have heard adults make these types of utterances which means they can be depicted as unique utterances, and since the meaning will be comprehensible, this utterance can also be viewed as a success. This all goes to illustrate that even at the first stages of language development children are showcasing their creativity. Most adults especially parents have heard their child/ran emulate them using adult expression and even intonation. With regards to creativity and language development, numerous researches from the theories L. S. Vygotsky (1967) and Jean Piaget (1962) cited in Gillen, 2009 has found that there is a substantial link between play and language learning. Play encourages childrenââ¬â¢s imaginative thought process through playing with objects that will then eventually lead to a better understanding of their environment. As the childââ¬â¢s ability to create more meaningful representations develop so does the more complex their play becomes. Bloom, 1993, p.216 cited in Gillen, 2009, p 56. Observed that a ââ¬Ëspurtââ¬â¢ in first words was usually due to development in play behaviours. From observations children unconsciously obtain rules about real-life behaviour, and implement what they have observed into their play with a mixture of their own imagination. When children are involved in pretence games with other children it is called sociodramatic play, within this type of play it is suggested that children practice different registers of talk that they observe to fit in with that role. To conclude it seems as though the interactions typically viewed of caregivers and infants are not essential and general characteristic initial language experience. There was a variance in comprehension and creation of vocabulary. Evidence derived from research of language acquisition is usually carried out from a limited collection of cultural and social backgrounds so the findings of primitive grammatical development in English are from language users of the normal criterion of the language. The section regarding play and language development suggests that creativity and imitation interlock, it appears that both coincide together it appears both weigh evenly in terms of forming spoken English.

Miss Julieââ¬Â by August Strindberg and ââ¬ÅDeath In Veniceââ¬Â by Thomas Mann Essay
The presentation of the theme and the main characters of ââ¬Å"Miss Julieâ⬠by August Strindberg and ââ¬Å"Death In Veniceâ⬠by Thomas Mann. The comparative study will examine the theme of lust and love, and the similarities between the two main characters from the play ââ¬Å"Miss Julieâ⬠by August Strindberg and the Novel â⬠Death in Veniceâ⬠by Thomas Mann. The main characters from each story come from a higher class, and they are expected to act noble, but somehow they both fail because of their desires for love and lust. August Strindberg wishes to portray a high class family that have certain standards and values, that Miss Julie; the daughter of the family, fails to fulfill. Miss Julie flirts with the servant and looses her virginity to him, her ââ¬Å"curiosityâ⬠for the servant results in her being dishonored by people around her. Her lust for the servant makes her weak and in the end she commits suicide because she was provoked by the servant called Jean. In Thomas Mannââ¬â¢s novel on the other hand, the main character is a man called Gustav von Aschenbach, who comes off as a conservative and somewhat ââ¬Å"religiousâ⬠man. He is a known author that travels to Venice and comes across a boy that fascinates him, his fascination makes him follow the young boy called Tadzio around Venice. Even at a young age Tadzio is well aware of his beauty, and he uses it to capture Aschenbachs attention and his curiosity. Aschenbach too, dies because of his love for Tadzio. Aschenbach gets poisoned by the cholera epidemic in Venice. He dies while watching Tadzio on the beach, he dies in his chair. Miss Julie is a daughter of a count and therefore she is wealthy, and has a full staff of servants. Miss Julie seems like a very extroverted person, she approaches the staff and talks to them. One in particular, the servant called Jean. One midsummer night Miss Julie grabs Jean and dances with him, but it was not a subtle dance, Jean describes it while talking to his fiancà ¯Ã ¿Ã ½ Christine. Jean: â⬠I took the count to the station, and when I came back by the barn, I went in and had a dance and there I saw a young lady leading the dance with the gamekeeper. But when she caught sight of me, she rushed right up to me and asked me to dance the ladies waltz with her. And ever since sheââ¬â¢s been waltzing like ââ¬â well, I never saw the like of it. Sheââ¬â¢s crazy.â⬠1 This is an example of how Miss Julie approaches people, in a confident way. When you read the dialogue between Jean and Miss Julie throughout the book, it is noticeable that Jean is doing all the talking, and ââ¬Å"philosophizingâ⬠, Miss Julie sits with him alone in the kitchen and listens carefully. Their situation is a problematic one, because even though Jean is Miss Julieââ¬â¢s servant he is also a man, and because of the time the story takes place, the man is above the woman. Miss Julie looses her virginity to Jean in the kitchen, and after Jean has sexual intercourse with Miss Julie he realizes that she has no honor or money herself. She realizes what her lust for him has made her do, she will now become dishonored by her dad and everyone around her. Jean disrespects her, even though he was the one who just slept with her, and Miss Julie doesnââ¬â¢t know what to do with herself? Julie: Help me, help me! Tell me only what I am to do ââ¬â where I am to turn? Jean: O lord, if only I knew myself! Julie: I have been exasperated, I have been mad, but there ought to be some way of saving myself. Jean: Stay right here and keep quiet, Nobody knows anything. Julie: Impossible! The people know, and Christine knows. Jean: They donââ¬â¢t know, and they would never believe it possible. Julie: (hesitating) But ââ¬â it might happen again. 2 This dialogue is a clear example of their relationship, Miss Julie seemed confident in the start, but because of her developing feelings for Jean she becomes insecure, and starts to ask Jean what do to. The play ends with Miss Julie following Jeanââ¬â¢s advice and committing suicide, so she would not have to confront her mistakes. She looses all her power, and nobility by sleeping with the servant. In the end it is obvious to observe that Miss Julie simply just wanted a man that could take care of her, and her lusts took over her common sense. Miss Julieââ¬â¢s dilemma is very controversial, because what she was doing was very common amongst the male aristocrats. This is a typical example of inequality between sexes! Thomas Mannââ¬â¢s controversial novel portrays a man called Gustav von Aschenbach who is an author that travels to Venice alone on a trip. When he arrives in Venice he is very observant, and he notices different people around him, acting silly and he almost gets appalled by their behavior. He saw an elderly man with a mask on, entertaining some younger people. ââ¬Å"They seemed to be tolerating his presence among them as something habitual and to taken for granted, they treated him as an equal, reciprocated without embarrassment when he teasingly poked them in the ribs. How was this possible?â⬠3 This is why Aschenbach is a very conservative man, who does not see beyond his own black and white world. This is one thing that changes on his trip, after checking in to his hotel, he notices a Polish family, amongst them there is a young boy who startles Aschenbach, his beauty startles him and the boy called Tadzio catches Aschenbachââ¬â¢s full attention. Aschenbachââ¬â¢s love and desire for the boy persuades himself to make up an excuse to stay in Venice, even though he was about to leave because of his bad health condition. His weeks in Venice result in him sitting by the beach and observing Tadzio. One day, Tadzio turns around and looks directly at Aschenbach, he stares at him in a cocky way, as if he is self aware of his beauty and how Aschenbach feels about him. Aschenbach merely convinces himself that he only has an ââ¬Å"abstract and artistic interest.â⬠Though it is obvious that he has gotten a serious obsession for him, and started to almost love him. The city of Venice was infected with a bad cholera epidemic, Aschenbach can smell how bad it had gotten, but instead of leaving or staying inside he continues to walk around, as if it is a sense of redemption for what he is thinking. Aschenbach knows himself that what he is doing, and thinking is wrong. His fascination for the boy has taken over his common sense. He does not approach Tadzio but he follows him around Venice, and he dreams about him, and discovers his sexual lusts. One afternoon he goes to the lobby and finds out that the Polish family is leaving, then even in his ill condition he goes to the beach to watch Tadzio for the last time. Tadzio is standing unsupervised by the beach and looking out at the water, he looks back at his admirer, Aschenbach tries to get up but falls back in his chair and dies. Miss Julie was written in 1888, and Death in Venice was written in 1912. There are not many similarities between the authors, and the styles these two stories were written in. Yet they do have similar themes and similar characters. Lust and love, was what drove both main characters to act differently, and controversial to what they are use to. They both die because of there actions, which were made because of their desires. Both the stories are tragedies but expressed in very different ways, one through a play another through a novel. Miss Julie and Gustav Von Aschenbach have both suffered, suffered what they normally would believe was a good thing, love. It was forbidden love and lust. Bibliography Strindberg, August. Miss Julie.

Arthur Miller increases the tension within the play Essay
In this piece of coursework I will be analysing the tragic play ââ¬Å"A view from the bridgeâ⬠specifically pages 35 to 42. I also will be discussing how the author Arthur Miller increases the tension within the play which continues to create an impact towards the later stages of the play. The play tells us a story of Eddie which has already happened. This is why Alfieri takes the role of two crucial characters in the play: a chorus and the role of a lawyer. When I say chorus I mean he doesnââ¬â¢t just tell us the story but reflects on the story as well as telling us what to feel and think of the tragedy, just like the ancient Greek chorus. I believe that the title ââ¬Å"A view from the bridgeâ⬠is a metaphor for the role Alfieri plays due to the reason that he is a Sicilian American lawyer who probably lives in a lat in Manhattan however he crosses the bridge to a poor estate called Brooklyn. This helps us understand Alfieri is a chorus that who is like eyes looking down from the bridge. When Alfieri says ââ¬Å"I knew, I knew then and there I could have finished the whole story then and thereâ⬠Alfieri using the technique of doubling shows that he is confident and tries to make the audience in awe of the play I also believe that miller created the character Alfieri as his voice to express his feelings and tell the audience what he Miller thinks through Alfieri because when Alfieri says ââ¬Å"it wasnââ¬â¢t as though a mystery to un ravel. I could see every step comingâ⬠this shows that Alfieri knows what will happen next yet unlike Miller, Alfieri is powerless to help Eddie this is shown when Alfieri says ââ¬Å"I sat here many afternoons asking myself why, being an intelligent man, I was so powerless to stop itâ⬠. The play uses a great deal of dramatic irony as a technique to keep us interested in the play due to the reason that we are privileged miller gives us insights into the play letting us the audience know what some of the characters are not aware of. For example, when Rudolpho says ââ¬Å"lemons are greenâ⬠trying to correct Eddie, Eddie replies ââ¬Å"I know lemons are green for Christââ¬â¢s sakeâ⬠Eddie says this in a angry tone leaving Rudolpho to wonder why Eddie just snapped at him like that however the audience know that Eddie is boiling with rage at Rudolpho who is stealing the women he loves and Rudolpho is everything Eddie cannot be The audience is also aware of the strain Eddie who is simmering with rage feels as he cannot deals with his love for Catherine. Alfieri sums up these feelings when he says ââ¬Å"we all love somebody, the wife, the kids ââ¬â every mans got somebody they love, heh? But sometimesâ⬠¦ thereââ¬â¢s too muchâ⬠¦ and it goes where it mustnââ¬â¢t. â⬠Eddie hates the fact that Catherine should have relationships with anyone except him. Eddie is jealous of Catherine and Rodolphoââ¬â¢s relationship because Catherine loves him and not Eddie: he doesnââ¬â¢t like the fact that his feelings are one way only Tension is built up by the lack of ability of characters to communicate. An example of this is when Beatrice says Eddie is not a proper husband: ââ¬Å"your wife gettinââ¬â¢ the money alright, Marco? MARCO ââ¬Å"oh, yesâ⬠this shows that Beatrice is indirectly asking to Eddie why he cannot be a proper husband and care for his wife like Marco does. However through what I have read and gathered. To my understanding Beatrice is very loyal, compassionate and patient towards Eddie as she knows about Eddies feelings towards Catharine. ââ¬Å"well be an uncle thenâ⬠when she says this Beatrice is trying to remind Eddie that he is only her uncle and nothing else. In addition to that she is also trying indicate that Eddie is being overprotective as if he is her boyfriend. Miller also builds up the suspense and tension at the end of act 1 by showing Marcoââ¬â¢s true strength when he lifts a chair from one corner with one hand keeping it straight, ââ¬Å"raised like a weaponâ⬠, above Eddieââ¬â¢s head. This leaves us with a sort of cliffhanger in which the end of act 1 has changed the course of the story and has added to the mystery of Marco and his relationship with Eddie. To wrap up I would say that Miller builds up the tension and suspense between 35 to 42 due to the reason that he is ending act 1 so he has to create suspense so that the audience come back for act two anticipating what will happen next. Show preview only The above preview is unformatted text This student written piece of work is one of many that can be found in our GCSE Arthur Miller section.

Acoustical Characterization of Porous Materials for Automotive Research Paper
Acoustical Characterization of Porous Materials for Automotive Application - Research Paper Example There exists diversity when it comes to porous materials either artificial or natural. Sintered, steel wool, perforated materials and fiber metal are among the porous materials that have been increasingly used in automotive noise control. Following the diversity and variety of porous material characteristics, the study of porous media has proved to be wide and interesting. The review begins with outlining and comparing the models that are intended to be used in predicting the fundamental acoustical characteristics that are applicable in automotive. The paper introduces both the theoretical, empirical and numerical modeling and demonstrates how the models are used to determine the acoustic characteristics of porous materials. The analytical models indicate that the solid constituents of porous material are rigid and the fluid constituents are similar to that of a homogenous isotropic fluid that has been modified. The review also considers the acoustical characterization of porous mate rials and goes further to look at the porous materials modeling while having particular interests on porous materials that are elastic. The fundamental characteristics of porous materials are then illustrated using computational and experimental examples . Introduction In automotive, absorptive materials have various applications in different locations. Absorber pads can serve effectively in several locations such as in the door panel, pillar trim, headliner and bellow the carpet. Porous materials like fibers and foams are normally used in such applications. There acoustic characteristics enable them to serve as absorbers. It is the viscous losses that results in the conversion of energy to heat while sound waves navigate through the fibers or pores that are interconnected in the material. A porous material that is bonded with a barrier that is non-porous conducts the sound energy in waves that are in form of structure-borne. The characteristics which have the desirable influence on this wave form are the structural loss and bulk stiffness (Allard, 1993,p. 56). With reference to automotive applications, absorption is preferred at frequencies that are lower while the weight and thickness are to be limited. Porous materials with air flows resistance that are specific yet different have been identified as to achieve the results that are desired. However, the action of decreasing or increasing the given air flow resistance in order to achieve low frequency results affect high frequency performances. The review thus gives a presentation of a number of different materialââ¬â¢s studies which illustrate such behavior. Several models such as the penalization approach demonstrate this behavior by simulating fluids inside and porous regions surrounding the obstacle. Such models are easy to implement and do not need a body fitting or a specific interface treatment. The models are successfully used in the introduction of new passive control methods that entail the imple mentation of a porous layer in between the fluid and the blue-body so as to change the characteristics of the boundary layer. Such a passive control model results in regularization that is drastic especially when it comes to high Reynolds numbers (Allard, 1992, p. 3349). Porous materials come in two phases, namely; the fibrous solid component termed as the frame and the interstitial fluid located in the pores resulting from the frame. Following their low density, porous materials cannot be generally used to make barriers but are commonly applied in the making of materials that absorb
