Smart Cards

1. Presentation Smart card is perhaps the best accomplishment in the realm of data innovation. Comparative in size to the present plastic installment card, the brilliant card has a microchip or memory chip inserted in it that, when combined with a peruser, has the preparing capacity to serve a wide range of utilizations. As an entrance control gadget, savvy cards can be utilized to get to server remotely over the Internet and they can make individual and business information accessible just to the suitable clients. Keen cards give information compactness, security, accommodation and so forth. As indicated by Gemplus (ref. 19]), keen cards can be ordered into the accompanying . Memory and chip Memory cards just store information and can be seen as a little floppy circle with discretionary security. A chip card, then again, can include, erase and control data in its memory on the card. Contact and contactless †Contact savvy cards are embedded into a keen card peruser, reaching the peruser. In any case, contactless brilliant cards have a recieving wire implanted inside the card that empowers correspondence with the peruser without physical contact. A combi card consolidates the two highlights with an extremely elevated level of security.Smart cards assist organizations with advancing and extend their items and administrations in a changing worldwide commercial center. The extent of employments for a brilliant card has extended every year to remember applications for an assortment of business sectors and orders. As of late, the data age has presented a variety of security and protection gives that have called for cutting edge shrewd card security applications. â€Å"Key to the worldwide village†,â that is the manner by which the Smart Card has been depicted. Savvy Cards will carry large changes to the manner in which individuals give and get data and the manner in which they go through cash. They will profoundly affect retailing and administration deli very.A Smart Cardâ is like a â€Å"electronic wallet†. It is a standard Visa estimated plastic smart token inside which a microchip has been installed inside its body and which makes it ‘smart'. It gives memory limit, however computational capacity too and in this manner the chip is equipped for handling information. It has gold contacts that permit different gadgets to speak with it. This chip holds an assortment of data, from put away (money related) esteem utilized for retail and candy machines to secureâ informationâ andâ applicationsâ for better quality tasks, for example, clinical/medicinal services records.New data and applications can be included depending the chip capacities. Savvy Cards can store a few hundred times a greater number of information than an ordinary Card with aâ magnetic stripeâ and can be modified to uncover just the pertinent data. For Example, it could tell a gadget in a store that there is adequate parity in a record to pay for an e xchange without uncovering the parity sum. The marriage between an advantageous plastic card and a chip permits data to be put away, got to and prepared either on the web or offline.Therefore, not at all like the read-just plastic card, the handling intensity of Smart Cards gives them the flexibility expected to make installments, to arrange your PDAs, TVs and video players and to associate with your PCs through phone, satellite or the Internet whenever, anyplace on the planet. 2. HISORICAL PERSPECTIVE Smart card was designed toward the finish of the seventies by Michel Ugon (Guillou, 1992). The French gathering of bankcards CB (Carte Bancaire) was made in 1985 and has permitted the dissemination of 24 million gadgets (Fancher, 1997). For the physical qualities the primary draft proposition was enrolled in 1983.A significant conversation brought about the normalization of the contact area. Next was the normalization of signs and conventions which brought about measures ISO/IEC 7816/ 1-4. Coherent security came straightaway, as it was obvious from the earliest starting point that there was a requirement for cryptographic capacities, however this was somewhat troublesome because of the constrained registering power and the couple of bytes of RAM accessible around then (Quisquater, 1997). These days, shrewd cards are utilized in a few applications. The innovation has its authentic starting point in the seventies when innovators in Germany, Japan, and France documented the first licenses. While creators in the U.S. , Japan and Austria, were given licenses, it was the French who put forth enormous cash to push the innovation. They did this in the 1970's, during a time of significant national interest in modernizing the country's innovation foundation. Because of a few factors most work on Smart Cards was at the innovative work level until the mid-eighties. From that point forward, the business has been developing at huge rate is transporting more than one billion (1 ,000,000,000) cards every year (since 1998). The current total populace of Smart Cards of somewhere in the range of 1. 7 billion is set to increment to 4 billion or more cards inside the following 3-4 years.A review finished via Card Technology Magazine (http://www. cardtechnology. com) demonstrated that the business had sent mutiple. 5 billion savvy cards worldwide in 1999. Throughout the following five years, the business will encounter consistent development, especially in cards and gadgets to lead electronic trade and to empower secure access to PC systems. An investigation by Dataquest in March, 2000, predicts very nearly 28 million keen card shipments (chip and memory) in the U. S. As per this investigation, a yearly development pace of 60% is normal for U. S. brilliant card shipments somewhere in the range of 1998 and 2003.Smart Card Forum Consumer Research, distributed in mid 1999, gives extra experiences into purchaser perspectives towards application and utilization of sav vy cards. The market of brilliant card is becoming quickly because of its wide scope of uses. The overall savvy cards showcase estimate in a great many dollars and billions of units as appeared in figure 1: 3. Development OF THE SMART CARD The primary stockpiling zone in such cards is normally EEPROM (Electrically Erasable Programmable Read-Only Memory),â which can have its substance refreshed, and which holds flow substance when outer force is removed.Newer Smart Card chips, some of the time, additionally haveâ math co-processorsâ integrated into the microchip chip, which can perform very mind boggling encryption schedules moderately rapidly. The chip association is either through direct physical contact or remotely by means of a contact less electromagnetic interface. Its chip in this way describes a Smart Card remarkably; with its capacity to store considerably more dataâ (currently up to around 32,000 bytes)â than is hung on aâ magnetic stripe,â all inside a very secure environment.Data living in the chip can be ensured against outside review or modification, so successfully that the crucial mystery keys of the cryptographic frameworks used to ensure the trustworthiness and protection of card-related interchanges can be held securely against everything except the most complex types of assault. The practical design of a GSM (Global arrangement of versatile correspondence) framework can be extensively isolated intoâ the Mobile Station, the Base Station Subsystem, and the Network Subsystem. Every subsystem is involved useful substances that convey through the different interfaces utilizing indicated protocols.The endorser carriesâ the versatile station;â the base station subsystemâ controls the radio connection with the Mobile Station. The system subsystem,â the principle some portion of which is the Mobile administrations Switching Center, plays out the exchanging of calls between the versatile and other fixed or portable system clients, just a s the executives of versatile administrations, for example, confirmation. Fig 3. 1. 1: Smart Card Construction. Fig 3. 1. 2: Smart Card Construction. For the most part all chip cards are worked from layers of contrasting materials, or substrates, that when united appropriately gives the card a particular life and functionality.The run of the mill card today is produced using PVC, Polyester or Poly carbonate. The card layers are printed first and afterward overlaid in an enormous press. The following stage in development is the blanking or kick the bucket cutting. This is trailed by installing a chip and afterward adding information to the card. Taking all things together, there might be up to 30steps in developing a card. The all out segments, including programming and plastics, might be upwards of 12 separate things; this in a bound together bundle that appears to the client as a straightforward gadget. 3. 1 Types of shrewd cards:Today, there are fundamentally three classifications of Smart Cards †A microchip chip can include, erase and in any case control data in its memory. It very well may be seen as a small PC with an information/yield port, working framework and hard circle. Microchip chips are accessible 8, 16, and 32 piece designs. Their information stockpiling limit ranges from 300 bytes to 32,000 bytes with bigger sizes expected with semiconductor innovation propels. 3. 1. 2 Integrated Circuit (IC) Microprocessor Cards †Fig 3. 1. 1: An Integrated Circuit utilized in Smart Cards.Microprocessor cards (for the most part alluded to asâ â€Å"chip cards†) offer more prominent memory stockpiling and security of information than a customary attractive stripe card. Their chips may likewise be called asâ microprocessors with interior memoryâ which, notwithstanding memory, epitomize a processor constrained by aâ card working system,â with the capacity to process information installed, just as conveying little projects equipped for nearb y execution. The microchip card can include, erase, and in any case control data on the card, while a memory-chip card (for instance, prepaid telephone cards) can just embrace a pre-characterized operation.The current age of chip cards has anâ eight-bitâ processor, 32KB read-just memory, and 512 bytes of irregular access memory. This gives them the identical handling intensity of the original IBM-XT computer, though with marginally less memory limit. 3. 1. 2. 1. Utilizations: These cards are us

Romeo and Juliet theatre production Essay Example For Students

Romeo and Juliet theater creation Essay For this bit of coursework I will investigate and clarify five tense and emotional scenes from the play Romeo and Juliet by William Shakespeare. Utilizing these scenes I will clarify how a creation at the Globe Theater could have been introduced to the crowd of the time, to expand the show and the characterisations. Likewise, I will consider how crowd response and cooperation have changed throughout the hundreds of years with differing ways to deal with the introduction of the story. Before continuing with this paper I will currently quickly clarify a portion of the components which harmonize with the prerequisites of this article question. For instance, I will give a concise rundown of the account of Romeo and Juliet, a blueprint of certain insights regarding the Globe theater, and a short audit of the remainder of the article question, for instance, a portion of the elements which would impact how a creation at the Globe Theater could have been introduced to the crowd of the time, to amplify the dramatization and the characterisations. The well known story of Romeo and Juliet, in light of the account sonnet, The Tragicall History of Romeus and Juliet by Arthur Brooke is an account of two darlings, as the introduction broadly alludes to as A couple of star-crossd sweethearts, who were covertly hitched and out of nowhere isolated all through their dreadful section of their demise markd love. The Globe Theater was, in the same way as other others, for example, the Rose, the Swan and the Fortune a lasting playhouse worked in London in the Elizabethan occasions. In 1596 James Burbage, a craftsman by profession, who possessed the Theater and the Curtain Theater ran into challenges when he attempted to restore the ground rent of the Theater. Exchanges yielded no practical arrangement, and James kicked the bucket, leaving his child Cuthbert to determine the issue. The last acted with brave and creative mind. With the rent due to lapse toward the finish of that year, on 28 December 1598 he had the structure destroyed by a woodworker called Peter Street and twelve laborers. It was evacuated to a real estate parcel on the opposite side of the Thames I Southwark, not a long way from the Rose. In under Eight months they constructed the Globe, the wonderful wooden O referenced by the theme toward the start of Henry V. Shakespeare, one of the five players in the Chamberlains organization turned into a householder in the Globe, as it were proprietor of an offer in the property. The Fortune, the Globe and the Theater had the option to suit crowds of somewhere in the range of two and 3,000. Elizabethan crowds were somehow or another more complex than the crowds of the twentieth century. For instance, when we go to see another play or (more probable) another film, we hope to discover the oddity in the activity. A portion of the circumstances might be natural; we might have the option to envision the closure; and the characters (who ought not be excessively not quite the same as the individuals we meet each day) may talk lines that we have heard before in different plays and movies. Be that as it may, we do request another story. Shakespeares crowds had various desires. They were glad to be given stories that they perceived, inasmuch as the producers treatment was new and person. It is conceivable to follow a source, or sources, for all of Shakespeares plays. Some of Shakespeares plays present very notable stories-Antony and Cleopatra, for example, or the scope of plays managing the range of English history from the hour of Richard II to the rule of Henry VI. Shakespeares examines were exhaustive: generally there is more than one hotspot for a play. Notwithstanding, this isn't the situation in Romeo and Juliet as in this play Shakespeare depends as a rule on an account sonnet, The Tragicall History of Romeus and Juliet by Arthur Brooke . The mix of interests and conventions In which Elizabethan dramatization accepted, for example, components from the Roman venue just as from Renaissance Italian and the mainstream Commendia dell arte, with its stock characters and half extemporized plots, which were notable to English screenwriters, similar to the impressive and declamatory catastrophes of Seneca, consolidated to make a mix of interests and customs which gave the Elizabethan show one favorable position that no cutting edge theater has. It made dramatization for the whole country. The uninstructed groundlings rushed to it as excitedly as the lettered supporters in the secured seats. The in vogue courageous was there however so was the energetic youthful researcher previously longing for acclaim and virtuoso. In this manner, from the earliest starting point the Shakespearean dramatization has one extraordinary opportunity; it doesn't need to channel itself to one layer of open taste. I can be lowbrow or highbrow as per the necessities of its topic. Be that as it may, this isn't its solitary bit of leeway. It has, what's more, the opportunity presented by the free creative mind. It's anything but a shopper craftsmanship however a specialty of investment. In Shakespeares day the performance center was a workmanship brimming with interest. In addition to the fact that it made utilization of verse, which brings the listener into a nearby association with the speaker. It additionally utilized the Ruth Draper strategy of making the crowd gracefully the visual foundation by creative mind alone. The outcome was an opportunity never again drew nearer until the start of radio show during the 1920s. Without hanging tight for (late) changes of unconvincing view, the activity can rush starting with one nation then onto the next, from the deck of a boat to the avenues of a city or from Mantua to Verona for instance. Notwithstanding, crowd support was not by any means the only manner by which the observer was moved nearer as one with the speaker and passed on a more clear image of the show being performed, there were numerous different components that impacted this. For instance, the portrayals and the language utilized by the characters would play as a lot of a significant job in doing this. Additionally, at times the setting, view and climate and props were incorporated to include shading and fervor, for example whirling blades in a fight scene would do this. Moreover, In the sixteenth and seventeenth hundreds of years Considering the time contrast among once in a while, somewhat similarly as in the venue today audio effects and music, made by an ensemble or apparatus would have been utilized at specific focuses to futher underscore certain characteristics of the speaker and of the show being performed. I will currently clarify, how these highlights and others could have been utilized while introducing the play Romeo and Juliet to a group of people of the time at the Globe Theater to respond to the exposition question. * Scene One: For my first case of a strained and sensational scene in the play, I have picked, and will allude to the preamble. This is the first of the scenes in the play and is hence significant as far as the play itself, as it lays the right foundation for what continues in the remainder of the exhibition. The scene is introduced to the crowd by the ensemble a solitary figure who isn't a character and has no character, his capacity is essentially to disclose the circumstance obviously to the crowd. The scene, which is generally short, as its motivation is essentially to clarify the circumstance, utilizes numerous emotional words and expressions so as to quietness an anxious crowd and settle the observers into a fitting state of mind for the main scene to initiate. In the scene numerous sensational words and expressions are utilized, for example, Two families, both the same in pride (respectable, noteworthy), insurrection (savagery), star-crossd sweethearts (doomed darlings) and yet their childrens end, nothing could expel (But nobody could stop the passings of their youngsters). These sensational words and expressions would not just catch the crowds eye and settle them down prepared for the primary beginning of the play to continue yet additionally upgrade the discourse made by the tune and the portrayals of the chorale which could additionally be re-upheld by solid, energetic non-verbal communication and expressive outward appearances, which would advance the characterisations of the ensemble and show feeling for the onlookers to get and decipher for themselves as a major aspect of crowd support in which, utilizing the data given by the Chorus the observers would, utilizing their creative mind flexibly the visual foundation and thus, explain for themselves what had been said. I will broadly expound on crowd cooperation as this coursework advances. What's more, music and view were presented in Elizabethan and Jacobean occasions and, as in other Shakespearean plays, for example, Twelfth Night which was loaded up with tunes and especially Anthony and Cleopatra in which irregular sounds were made, for example, the clamor of an ocean battle, emotional audio cues may have been utilized at one point in the scene, either to add surface or to upgrade certain characteristics being performed. For this situation sensational audio cues may have been utilized so as to flag the finish of an introduction and the beginning of the principal scene. In addition, this may have been to a greater degree a need than an extravagance as the venue had no drapes or power outage to show the finish of a scene or act. Likewise, Shakespeare wouldnt fundamentally have demonstrated the parts of the bargains. In this manner, these audio cues would not just make crowd expectation and include energy, as the observers anticipate the opening of the play, yet in addition all the more significantly educate the crowd that the beginning of the play was initiating, also along these lines the onlookers would not get lost between the scenes. Interims between acts were presented in the fresher indoor theaters, though, as just referenced the outdoors theaters, for example, the Globe would in general play without a break. The indoor auditoriums had a preferred position in that they were secured over, so exhibitions could be arranged in awful climate and they were likewise lit by candles so exhibitions could be organized at night. Be that as it may, the more seasoned, amphitheater-style theaters, for example, the Globe would likely have made a more unrivaled air than the more up to date indoor performance centers as the crowd at theaters, for example, the Globe were presumably unquestionably increasingly fluctuated, including the most extravagant and

A high-quality research project involves the use and analyzation of other, outside sources, and connecting them to the thesis or argument. These other sources are generally primary and secondary sources. There are numerous places to find both types of sources and there are benefits to including both in a research assignment. Primary sources are original pieces of work. We use primary sources to help us learn about an event, topic, or historical time period. Primary sources include: letters diary entries original photographs reports speeches surveys newspaper articles that are published directly after an event artwork performances ….and many more Primary sources require students to develop their own analysis and argument since the primary source doesn’t include an evaluation from others. An example of a primary source is The Treaty of Versailles, which was an important document that brought World War I to an end. It is considered a primary source because it is a raw document that students themselves can interpret, critique, and analyze. Other examples of primary sources include Anne Frank’s Diary, The Declaration of Independence, Martin Luther King Jrs I Have a Dream speech, and Leonardo DaVinci’s Mona Lisa painting. Secondary sources interpret, critique, or analyze primary sources. Creators of secondary sources look at primary sources, develop meaning from them, and create their own analysis of the primary source. Secondary sources can include: reviews essays newspaper articles that analyze or discuss older events/ideas comments on blogs and articles textbooks Students should include secondary sources in their research projects as these sources provide evidence to strengthen their own argument and helps them learn about different perspectives. An example of a secondary source is the book titled, The Treaty of Versaille: A Concise History, by Michael S. Neiberg. In this book, the author analyzes the entire treaty, piece by piece, and evaluates how the treaty affected the world after its establishment. Another example of a secondary source is the website, Rotten Tomatoes, which provides reviews of films and movies. This video, Primary and Secondary Sources, provides students with an introduction to both terms and what they mean examples of each source type reasons as to why it’s important to use both types of sources in research projects Share this video with your students to help them understand the difference between these two types of sources and the reasons as to why they should be used in their research assignments.

The Compromise of 1877 Set the Stage for Jim Crow Era

The Compromise of 1877 was one of a series of political compromises reached during the 19th century in an effort to hold the United States together peacefully. What made the Compromise of 1877 unique was that it took place after the Civil War and was thus an attempt to prevent a second outbreak of violence. The other compromises, the Missouri Compromise (1820), the Compromise of 1850  and the Kansas-Nebraska Act (1854), all dealt with the issue of whether new states would be free or slave and were intended to avoid Civil War  over this volcanic issue. The Compromise of 1877 was also unusual as it was not reached after open debate in the U.S. Congress. It was primarily worked out behind the scenes and with virtually no written record. It arose out of a disputed presidential election that nevertheless was tinged with the old issues of North against South, this time involving the last three Southern states still controlled by Reconstruction-era Republican governments. Election of 1876: Tilden vs. Hayes The timing of the agreement was prompted by the presidential election of 1876  between Democrat Samuel B. Tilden, governor of New York, and Republican Rutherford B. Hayes, governor  of Ohio. When the votes were counted, Tilden led Hayes by one vote in the Electoral College. But the Republicans accused the Democrats of voter fraud, saying they intimidated African-American voters in three Southern states, Florida, Louisiana and South Carolina, and prevented them from voting, thus fraudulently handing the election to Tilden. Congress set up a bipartisan commission made up of five U.S. representatives, five senators and five Supreme Court justices, with a balance of eight Republicans and seven Democrats. They struck a deal: The Democrats agreed to allow Hayes to become president and to respect the political and civil rights of African-Americans if the Republicans would remove all remaining federal troops from Southern states. This effectively ended the era of Reconstruction in the South and consolidated Democratic control, which lasted until the mid-1960s, nearly a century. Segregation Takes Over the South Hayes kept his side of the bargain and removed all federal troops from Southern states within two months of his inauguration. But Southern Democrats reneged on their part of the deal. With the federal presence gone, disenfranchisement of African-American voters in the South became widespread and Southern states passed segregationist laws governing virtually all aspects of society -- called Jim Crow -- that remained intact until the Civil Rights Act of 1964, passed during the administration of President Lyndon B.Johnson. The Voting Rights Act of 1965 followed a year later, finally codifying into law the promises made by Southern Democrats in the Compromise of 1877.

How are gender relationships depicted in Chaucers “Wife of Bath” Free Essays

The Wife of Bath’s Prologue and Tale is one of the twenty-four stories which make up The Canterbury Tales written by Geoffrey Chaucer towards the end of the 14th century. The premise for The Tales is that of a group of pilgrims each telling stories in order to win the prize of a free meal, the primary narrator is a naà ¯ve pilgrim who is not described. The Canterbury Tales is written in Middle English, which bears a close visual resemblance to the English written and spoken today. We will write a custom essay sample on How are gender relationships depicted in Chaucers â€Å"Wife of Bath†? or any similar topic only for you Order Now The Tales were unfinished as Chaucer died before their completion and the order of the stories has been disputed due to the fragmented nature of his work. This essay will be looking at gender relationships in The Wife of Bath’s Prologue and Tale and in medieval Literature as a whole. Chaucer’s Wife of Bath is a middle-aged woman from the west country, who strides into The Canterbury Tales on a large horse with her spurs jangling and riding in the fashion of a man rather than the side saddle that was typical of women, ready to assert herself in the company of pilgrims made almost entirely of men. Rich and elaborate in design, the Wife’s clothes reek of extravagance, her stockings â€Å"weren of fyn scarlet reede† and â€Å"on hir feet a paire of spores sharpe† show how wealthy she has become from her conquests of men. In the General Prologue where each of the characters is described in terms of their profession she is clearly a ‘professional wife’ who has travelled more than almost all of the other pilgrims making her a bold, adventurous and sociable character. Men were the ones who travelled to distant lands in search of adventure, this challenges the accepted ideas about gender of the time. This portrait of a woman is very peculiar for a piece of medieval literature, men tend to have the starring role and women are usually featured as beautiful ladies in distress or as villainous old hags. The Wife of Bath is neither a helpless damsel in distress nor a typical old crone. She is the first of her kind in English literature. The Wife of Bath’s Prologue is the life story of Alison who has married five times, this in itself is unusual for a woman in medieval literature as it is usually the rogue male who has multiple lovers. Chaucer certainly informs us of Alison’s backstory to a higher degree than he does the other pilgrims. There are many pieces of literature which condemn women, from the highest class to the lowest, Chaucer does not ignore this with his characterisation of the Wife but rather embraces it to make her who she is. The Wife is noisy and bossy, she torments her husbands and has a large enough sexual appetite to compete with the most sexual of men. But Chaucer has also made her capable of love, vulnerable, optimistic and argumentative against medieval anti-woman ideas. It is not clear whether Chaucer wants us to sympathise with the Wife and see her as the first feminist and defender of women’s rights or if we are to view her as an elaborate joke of what would happen if a women were to ever have as much freedom as a man. The Wife of Bath’s Prologue is different from any literature which had been encountered, as is her Tale. The male lead is not a typical heroic knight but a rapist, the main female role is an ugly old woman and the force of good in the story is a court full of powerful women. All the standard ideas of gender relationships are both turned on their heads and brought into sharp focus. The Wife conforms to a number of anti-female stereotypes of the medieval period, stereotypes which were created by men for the purpose of a patriarchal society. She claims that she has a great sexual appetite whilst also boasting that she uses sex to gain wealth. The Wife also tells of how she controls her husbands through the use of her body, a fear which is common of villainous females in medieval literature and which males dread. The Wife points out that there are many husbands and wives in the Bible. Some of the greatest men in the Old Testament were not only married but had multiple wives. â€Å"Lo, heere the wise kyng, daun Salomon; I trowe he hadde wyves mo than oon. As wolde God it leveful were unto me To be refresshed half so ofte as he!† (35-38) This is a double standard in that these men have multiple lovers but that women apparently can’t. By calling King Solomon â€Å"wise† she is conveying that wise men have multiple marriages. The Wife successfully gives examples from the Bible of people whose marriages were blessed by God despite the polygamous nature of these marriages. The Pardoner who is shocked by the Wife’s revelations so far interrupts her story, he says that he was about to marry but is now not so sure that it is a good idea. â€Å"Now, dame,† quod he, â€Å"by God and by Seint John!†¦ I was aboute to wedde a wyf; allas!†¦ What sholde I bye it on my flessh so deere? Yet hadde I levere wedde no wyf to-yeere!† (164-168) The Wife then tells a short story about a medieval pardoner who worked for the Church collecting donations from those sorry for their sins and anxious to find forgiveness. His manhood is called into question throughout the canterbury tales and his talk of taking a wife is probably an empty boast. This is a continuation of Wife of Bath’s theme of male impotence, she regularly taunts her celibate male adversaries in this way throughout the prologue. It was unheard of for a woman to speak this way about such matters, even a man would think before directly insulting men of the Church. The first three husbands the Wife had were rich old men who were financially secure. The Wife treated each of these husbands badly and in a very dominating way. By being argumentative and eager to start trouble she ensured that they would be careful to please her. â€Å"What sholde I taken keep hem for to plese, But it were for my profit and myn ese?† (213-14) Here the Wife of Bath uses a rhetorical question, it is clear from the tone that she doesn’t think she needs to care about her husbands. The misogynists classed all women together as bad and all wives as nothing but trouble. Chaucer both confirms this stereotype here with the way the Wife treated her first three husbands but also turns it around so that the woman is in control for once and the men are indistinguishable without even a single name between them. Chaucer makes us pity the husbands but it also shows us how unfairly women are usually treated. Chaucer outlines the Wife’s general techniques on how she handles Marital trouble which are lying, cheating and accusing the opposite gender before they accuse you. Lying and cheating were the things that medieval literature always accused the villainous women in a story of doing. The Wife is therefore acting in a very stereotypically manipulative way, and comes very close to becoming the old villainous hag which was a staple of medieval literature. Chaucer makes it clear that the Wife is a complex character and that our response to her as readers should be one of uncertainty. He makes sure we see the good aswell as the bad. The Wife of Bath goes on to describe the lies she would use to keep her first three husbands in line. She’d accuse them of lecherous behaviour and of chasing after the neighbours or servants and then unfairly accusing her about her relationship with her ‘friend’. She uses powerful but offensive imagery towards woman in order to get her point across. â€Å"For as a spanyel she wol on hym lepe,†¦ But folk of wyves maken noon assay, Til they be wedded — olde dotard shrewe! And thanne, seistow, we wol oure vices shewe.† (267-292) The Wife of Bath uses simile’s to compare women first of all to animals, which should be tried by men before they are bought. They are then reduced even further being compared to ordinary objects such as basins, washbowls, spoons and stools. The men did not say these things and this paints the Wife of Bath in a very negative light for her deceit but at the same time other men during her period are guilty of thinking such things. The Wife boasts about how she lied to her husbands about what they said whilst drunk in order to make them feel guilty. This extract is some of the Wife’s most blatant deceit and if all women were to be like this in medieval times it would be surprising if men and women ever managed to live together at all. â€Å"Thou liknest eek wommenes love to helle, To bareyne lond, ther water may nat dwelle. Thou liknest it also to wilde fyr;† (371-372) The Wife doesn’t see the wickedness of her ways as is obvious when she states â€Å"Yet tikled I his herte, for that he Wende that I hadde of hym so greet chiertee!† The choice of verb is an interesting one because it is much lighter than the passage as a whole. The Wife claims that either her or her husband must give in if they are to live in peace, and she says â€Å"And sith a man is moore resonable† he should be the one to give in more easily. She then slyly puts in a comment about how she is his alone, implying that this could easily change at any moment. She is exploiting male and female stereotypes here, using a man’s image of themselves as reasonable and superior against them. She is manipulating by saying that if women are so stupid and emotional, clever men should just let them have their way in order for there to be peace. The Wife of Bath’s youth may have now passed her by but she has no regrets. Her fourth husband however was not a very happy memory for her. She even goes on to tell us about his unfaithfulness â€Å"This is to seyn, he hadde a paramour†. Her dominance and power over her first three husbands now gives way to the more melancholy story of her next husband. Old women in medieval literature quite often show bitterness and loathing when they remember their youth but the Wife has no regrets. Her optimism and her grace in the way that she accepts the passing of her youth shows a softer and more vulnerable side to this manipulative and domineering woman. With the death of her fourth husband The Wife then falls in love with a man named Jankyn who was half her age. Within a month she had married him and as an act of love she signed over all her property to him. However, Jankyn was typical of a medieval gender role. He was a dominant man who won’t be told what to do by a woman. He demands her to stop going on pilgrimages, stop gossiping and to generally stop all the mischievous behaviour from her past. He beats her for tearing pages out of a book and tells her of husbands who left their wives because the wives would not do as they were told. â€Å"And me of olde Romayn geestes teche; How he Symplicius Gallus lefte his wyf, And hire forsook for terme of al his lyf† (642-644) The Wife now has to be on the receiving end of the abuse that she has up until then caused, she is the one being dominated and controlled. She has previously been at a distance from the anti-women literature of the period, even used it to her advantage against her past husbands. Now she must endure the stereotypically male dominated household she has avoided for so long. The reason the Wife of Bath is deaf is because she was struck by Jankyn for tearing out a few pages from his favourite book. It consisted of stories by the best known authors of the middle ages which condemned women. â€Å"For trusteth wel, it is an impossible That any clerk wol speke good of wyves,† (688-689) She hated this book as Jankyn used it to cause her a great deal of grief, she stated that these men don’t understand women yet they are the ones writing these stories. What’s quite interesting is that all the literature she used to control her past husbands was now coming at her in a very real sense. The Wife of Bath asks the question â€Å"Who peyntede the leon, tel me who?† which points out that medieval women existed in a world where everything including art, religion, work, family life and literature was controlled by men. Chaucer pointing this out is well ahead of his time in terms of social gender commentary. The Wife’s ripping of the book could be seen as a symbolic gesture. The Wife used this literature against her past husbands, she had it used against her by her fifth husband. The tearing of the book is symbolic of the Wife moving away from medieval stereotypes. After finally finishing the prologue to her story the Wife of Bath moves onto her Tale. The story opens with the rape of a young maiden, the rape is described very casually as though it is somehow entirely natural that a woman is violently attacked this way. â€Å"He saugh a mayde walkynge hym biforn, Of which mayde anon, maugree hir heed, By verray force, he rafte hire maydenhed;† (886-888) The word ‘raft’ means he took her ‘maydenhead’ which is not a very violent verb but it still has powerful imagery because of how casual a word it is. This can be seen as an extreme example of the way in which women are regarded as mere property. The knight’s offence was against a woman so it is therefore ironic that women should step in to save his life. They don’t do this out of compassion or mercy though, he is to be placed in a powerless position in which the fate of his body is in the hands of another, similar to when a woman is raped. After a year of searching for the answer to the question of what women want the knight rides back to the court in despair, this is when he encounters an extremely ugly old woman who agrees to give him the answer to his question if he agrees to do something for her. After answering with â€Å"†Wommen desiren to have sovereynetee† the old hag asks the knight to marry her. Because our knight did not know what the condition would be he is placed in a far more vulnerable position. He is completely under the old woman’s dominance, a reversal of the normal male female relationship. The â€Å"lusty bacheler† from the start of the story now â€Å"hidde hym as an owle†, no longer dominant and in control or a stereotype of medieval man. The old woman then gives the knight an ultimatum, she can either be beautiful and unfaithful or faithful and ugly. The knight considers for a moment but decides in the end to let her make the decision which results in her being both beautiful and faithful. With the mastery handed over to the old lady, there is a switching of gender roles with the knight also getting what he wants. The knight is no longer the misogynist monster he was at the start of The Wife of Bath’s Tale. It could be argued that the Wife of Bath is giving a voice to the excluded women of medieval society. Through her voice we hear and see all the devaluation and oppression which is always silent in medieval literature due to the authors being almost entirely male. The Wife could also be interpreted as a representation of stereotypical medieval fear by men about women as cruel, emotional and sexually deviant. It is not clear in what way Chaucer meant for her to be conveyed, it is clear however that he wanted her to become a complicated character with many different layers whose gender was a driving force for the story.

Public Relation Campaigns for Australian Media - MyAssignmenthelp

Question: Discuss about thePublic Relation Campaigns for Australian Media. Answer: Public relation campaigns have a long history of evolution in the Australian context. If you ever find a chance to look into the history of such campaigns you will be utterly surprised. You would be surprised to witness the variety of subjects that the public relation campaigns in Australia have encompassed in the past. An avid researcher would definitely find it interesting to explore the world of public relation campaigns in Australia, and she would be quite willing to indulge in the process of analyzing the true nature of the concerned campaigns. It must be noted in this regard that often, from the critical perspective, the public relation campaigns in Australia have been identified as interpretive means rather than factual ones (Sheehan, 2007). Moreover, the influence of the United States as the initiator of public relation campaigns in Australia should also be taken into account in terms of attributing such campaigns with symbolism rather than factualism. But whatever might be the nature of the Australian public relation campaigns, both its advocates and critiques have found it fit for the socio-political environments in which their inception took place. Since the arrival of the US forces in 1942 the realm of public relations and the related campaigns have remained largely dominated by the American public relation culture (Sheehan, 2007). This truth is undeniable and you are going to find the truth in the very nature of the Australian communication style. What can be more interesting for you to discover is the fact that in every phase of the evolution of human civilizations efforts of either promoting the ruler or the divine beings had been observed, and this promotional feature eventually paved the way for the emergence of modern public relation campaigns. In this context it the impact of the U.S. public relation style on the Australian public relation campaigning style should not be criticized; rather, it should be considered a natu ral process, keeping in mind the fact that modern public relation campaigns are actually the outcome of ancient influences, may it be the promotional campaigns of Alexander of Macedonia or the divine promotions of the pharaohs of Ancient Egypt. So, it should be taken as a natural phenomenon that one advanced society would be influenced by another advanced society in terms of promoting their cultural, social, political and economic resources. Though in the context of public relation campaigns in Australia, the major influence of the United States has again and again been pointed out; it would be impossible for an individual to deny the truth that such influence is natural and that; Australia also gave birth to pioneers who changed the face of public relations forever. The Australian pioneers reshaped the field of public relations and they brought about immense changes to the context by adding their indigenous charm to the spell that was cast by the U.S. public relation culture on the Australian counterpart. And it was this blending which gave rise to a unique public relations culture that has been, till date, References Sheehan, M. (2007).

The Eruption of Toba

Introduction The largest volcanic explosion in the late Pleistocene occurred in Lake Toba, approximately 72,500 (+- 3000) years ago. The super eruption of Toba has attracted a lot of scientific disrepute due to various reasons. When viewed from space, the caldera is observed as one of the biggest volcanic craters on earth, since it measures over 100km.Advertising We will write a custom research paper sample on The Eruption of Toba specifically for you for only $16.05 $11/page Learn More On the steep was of the caldera is lake Toba. This lake is said to be the largest volcanic lake on earth. Various scientists including Gasparotto, Spadaforab, Summac, Tateoc, Spadafora and Summa (567) and Jones, Gregory and Stott (725) sugest that the eruption resulted in a massive volcanic winter that caused a human population bottleneck. Super-volcanoes are colossal eruptions that are referred to as super-eruptions, and they vary from other catastrophes like tsunamis or earthquakes since their environmental outcomes threaten global civilization (Buhring and Sarnthein 277). These super eruptions are known to occur once in about 500,000 years, like the largest Yellowstone eruption in the USA, or the Toba eruption in Indonesia. Figure 1: Distribution of volcanic ash from the 73 ka Toba super-eruption showing location of marine cores and sections sampled in India According to Ninkovich, Sparks and Ledbetter (5), super-eruptions occur in areas of the earth where the tectonic plates collide. Ambrose, Williams and Chattopadhyaya (167) also suggest that super-eruptions can occur in areas where hot material wells up from the deep earth interior below a continent.Advertising Looking for research paper on geography? Let's see if we can help you! Get your first paper with 15% OFF Learn More According to Williams and Clarke (633), there are many regions on earth that are suspected of volcanic activity, like Andes and Japan. A cause for concern i s the location of super-volcanoes within or near continents, which impies that these vents are situated in areas that have crowded populations (Lang, Leuenberger Schwander 934). This paper looks at the eological setting of Toba, in an effort to understand the super eruption and its probable effects. In doing this, this study seekd to validat that the eruption resulted in the putative bottleneck. Table 1:  Particle size distribution of the YTT ash at the Rehi section, Son valley, India. Geological Setting of Toba Toba is located in western Indonesia, in the island of Sumatra, in the north province. It is found in the Barisan Mountains as shown in figure 1. Fig. 2: Tectonic setting and location map (inset) of the Toba Caldera. Tectonic map modified from Simkin et al. (2006).Advertising We will write a custom research paper sample on The Eruption of Toba specifically for you for only $16.05 $11/page Learn More These mountains comprise metamorphic rock s, Quaternary volcanic and Miocene sedimentary rocks (Ambrose 274). De Silva (671) suggests that Indian-Austrlain plate located beneath the continental Eurasisn subdues a the rate of aproximately 5.5cm.year, towards the Sunda trench, which has resulted in the formation of an active volcanic (Gathorne-Hardy and Harcourt-Smith 228). Sadler and Grattan (186) suggest that the crust is about 30 to 39 km thick under Toba, with a visible depth of around 125 km (De Silva 671). This is an indication of a 30 degrees subduction angle, which has caused the formation of two parallel faults that lie between the trench and vulcanic arc. One of the faults, the vertical Sumatran, marks the border between the Eurasian plate and most of the Volcanic arc and fore arc basin on the north east and south west respectively. The other fault, Mentawai, forms the division between the fore arc basin and the fore arc accretionary sridge complex in the southwest direction (Erwin Vogel 894). According to Westgate , Shane and Pearce there is a dxtral displacement aong the Sumatran Fault. The displacement extends for about 150 km. It is referred to as the Investogator Ridge Fracture Zon (IFZ), with a subduction that is directly nelow Toba. The results of a geometry assessemt of the subduction slab beneath Toba by Chesner et. al. (201) suggest that there is a bend in the slab that coincides with Toba.Advertising Looking for research paper on geography? Let's see if we can help you! Get your first paper with 15% OFF Learn More The study also showed high seismicity along the subducted portion of the IFZ, which suggests the probability of IFZ concentrating volatile release into the mantle wedge beneath Toba (Chesner et. al 201). Figure 3: Bathymetric map of Lake Toba. Depth is represented by isochromes; 100 m contour lines are plotted for reference. The Toba Super eruption The single event of the Toba eruption resulted in a minimum magma eruption of 2,800 km. The magnitude of the eruption was noted as 8.8, which made it one of the largest eruptions in the Quaternary geologic period. The super eruption caused an injection of over 1015 kg of fine ash into stratosphere, while the pyroclastic flows extended for an area of approximately 105 km2 with lava reaching both the Malacca straits and the Indian Ocean. Kelly, Jones and Pengqun (550) suggest that there are layers of tephra in India, at a location that is over 3000 km away from Toba. The ignimbrite extended from one coast to the next, causing a wide area o f the North Sumatra to be drowned. Moreover, there was an aerosol cloud and dust cloud that covered the globe. The possible effects of the cataclysmic eruption include the total obliteration of both flora and fauna in North Sumatra by the ignimbrite, considerable effects on flora and fauna by ash fall in Southeast Asia, as well as, the regional or global change in temperature and effects on the environment. The Toba Catastrophist Theory The Toba catastrophe theory suggests that the super-eruption resulted in the population decline. Scientists suggest that the super-eruption is the worst disaster that human beings have ever been faced. The volcano eruption in Toba resulted in the exhaustion of large amounts of fine ash and aerosols into the atmospheres. The expulsion of these fumes is compared to nuclear-winter situations (Samuel, Harbury, Bakri, Banner Hartono 350), since the global land temperatures fell by 5-15 degrees Celsius, and the surface of the ocean, and other low altitude s, cooled by 2-6 degrees Celsius. This scenario is thought to have prolonged for several years. As a result, the persistence of soot in the atmosphere for 3 years or so may have resulted in a cooling of the climate (Pattan, Shane Banakar 244). This climatic change is though to have extended for several decades, due to the climatic feedbacks such as increased snow cover and sea ice, resulting in less solar radiation reaching the earth’s surface. Consequently, the earth’s temperature remained low since the ground and atmosphere were not heated up. Researchers suggest that the human population faced a bottleneck during this period, due to the rapid decline in the number of females by about 500, in a population that was thought to have only 4000 individuals (Hawks, Hunley, Lee Wolpoff 18). Data suggests that the eruption caused a peak in sulfur aerosol levels in the GISPs ice core, in addition to the global climatic change. According to ice core data, the weather was coo ler for several centuries after the eruption of Toba. Based on the estimates, the Toba eruption resulted in the near extinction of modern humans. Ambrose, Williams and Chattopadhyaya suggest that this led to the human population, though Oppenheimer (1593) provides an alternative hypothesis, arguing that the Toba super-eruption did not have a significant effect on human existence. Oppenheimer (1593) suggests that human beings should not have been the only ones facing termination. According to Rose and Chesner (913), the Toba induced winter should have resulted in an environmental catastrophe resulting in a population crash of more specialised ecological flora and fauna, causing them to be extinct, in a similar manner that it affected human population. In support of this notion, Gates and Ritchie suggest that the Toba super-eruption did not lead to the extinction of any mammal. In adtion to this, studies by Gathorne-Hardy and Harcourt-Smith (228), on the effects of super-eruptions on flora and fauna suggest that they do not result in mass extinctions, which disapproves the Toba catastrophe theory. According to Gasparotto, Spadafora and Summa (569), a bottleneck in human populations would have assumed the shape of an hour glass, causing the human population to crash at 73.5 Ka and then expand again later. According to Schulz, Emeis and Erlenkeuser (22), the studies on human genome that analyse nuclear sequences suggest that the Y chromosome and mitochondrial DNA support the existence of a bottleneck. Consequently, Robock, Ammann and Oman (114) support the possibility of a bottleneck, though they raise concerns about the time when the bottleneck is expected to have occurred. Some research suggests that the phenomena occurred over 2 million years ago (Petraglia, Clarkson and Ditchfield 114), while other researchers provide evidence of a long period of stasis that was followed by a population expansion around 75,000 years ago. The different opinions with regard to t he bottleneck differ on the timing of the event, which raises concerns as to whether it was caused by the super-eruption at Toba. Differences also arise based on the shape of the bottleneck, in terms of an hourglass model or a short bottle with a long neck. The hourglass model suggests a short period of human population decrease, followed by an expansion, while the long neck period indicates a proonged period of winter, and low population density (Rampino and Ambrose 274). However, the hourglass shaped bottleneck is dispreuted due to its timing of the expansion, which is proposed to have a minimum range of 50,000 years. Consquently, the super-eruption of Toba was unlikely to have resulted in the bottleneck (Rampino and Self 75). In addition to this, studies by McBrearty and Brooks on the Middle and Late Pleistocene human sites in Africa show that by 73.5 Ka, modern humans occupied a variety of habitats around the African continent. The human beings were also noted to be considerably adaptable and resourceful, with the ability to hunt and perform other tasks requiring skill (Westgate, Shane and Pearce). Conclusions In conclusion, it has been established that the super-eruption of Toba resulted in a severe climate change; however, there is inadequate evidence to support the notion that it caused a bottleneck in human population. Studies suggest that the effects were localized. In addition to this, research shows that the super-eruption had negligible effect on the Asian population, and none in Africa. During the time, human beings were adaptable, mobile and well equipped, which made them fully capable of handling the effects of the Toba phenomena. Moreover, the studies suggest that the super-eruption did not result in the extinction or decline of any fauna. Consequently, it is evident that the super-eruption of Toba did not result in human, flora or fauna bottleneck (Thornton 34). Figure 4: Sonar profiles along selected transect lines.

Antonio vivaldi essays

Antonio vivaldi essays My first circumstantial listening or contact with this classical, instrutmental music, which dates back to 1725, is one subconsciously by accident. More times than I can count, I recall hearing this music in classical and modern movies. This music usually played the foreground position to the smiling faces of people who ballroom danced in unison or the background music, which was played for the queen and her subjects as they gathered on a joyous ocassion, like a wedding. Nonetheless, the music causes me to envision very classy, elegant and wealthy people wearing their best gowns and three piece suits as they gallop and courtesy around the palace. This music certainly, did not make me feel sad or full of sorrow as did Richard Wagner's very solitude piece, which was outlined in class. Infact Vivaldi's piece, First movement or introduction of Spring from his masterpiece The Four Seasons, was very similar to Franz Haydn's Symphony 51, which is full of high energy and unmistakable highs and lows. However, where Symphony 51 seems to be rather unorganized, the Spring introduction appears to be a combination of structured dance music, that is rythmically predictable. Similiar to The Sea Interlude by Benjamin Britten, the textural value of Antonio Vivaldi's first movement into Spring is simple, because it is the clear soundof the violin and strings flourishing, as oppose to many instrutments intertwining at once. Unlike Beethoven's Ninth Symphony, which is midway between being simple and extremely complex and expresses a series of ideas, Vivaldi's music has a clear goal and contains gesture, which is responsible for the whole classical, ballroom dancing atmosphere. Vivaldi's music is greatly respected and appreciated because, not only does it sound appealing to the ear for nonmusicians to understand, but it also causes the listener to feel good because this music is enormously uplifting and positive. Certainly one, is familiar with ong...

Macroeconomics (Economics in general) Essay Example | Topics and Well Written Essays - 7500 words

Macroeconomics (Economics in general) - Essay Example Various terms and assumptions are taken in economics in order to understand the behavior of individuals, society as a whole and the patterns of production and spending. Scarcity is one such concept used in economics to define and explain behavior and relationship among the key variables, that is, spending and production. Scarcity refers to scarcity of resources meaning that the resources available for ay economy are scarce and thus should be used efficiently in order to produce maximum outputs. Economic goods are goods where the consumer has to pay some price to acquire them and/or to consume them. On the other hand, the non-economic goods or simply the free goods have no opportunity cost. The consumer does not have to let go anything in order to use these goods. Goods involving a financial cost or any other type of cost are classified as economic goods. Economic goods can be anything that is purchased for consumption at some price. The price is determined by the interaction of supply and demand for that particular good or service. All goods that are sold for some price are economic goods in economic terms. Non-economic goods are those that are available for free. They can be in the form of air, government provided goods and services. As they are not costing anything, they have no opportunity cost either. The acquirer does not have to pay anything for its use. ... They can be in the form of air, government provided goods and services. As they are not costing anything, they have no opportunity cost either. The acquirer does not have to pay anything for its use. Similarly, they are not scarce in nature. Economics and scarcity are related as economics study the individual's behavior of making choices between available goods. The decision is primarily based on the opportunity cost, marginal utility and the scarcity of good and/or service. Economics, thus, has close relation with the concept of scarcity. Economics is the study of the decisions that households and firms make in any economy and their impact. Market Mechanism 2. Describe the market mechanism of supply and demand and describe how they operate in competitive markets to produce equilibrium. Market is a place where the buyers and the suppliers interact. The buyers are the consumers and/or customers of any sort of good or service. The suppliers are the providers of the required good or service. The market operates because of the interaction of buyers and suppliers. The buyers express their willingness to buy a particular good or service. The suppliers at the same time provide the required good or service. The degree of demand ad the level of available supply of that good or service determines the market price for that product. The interaction of supply and demand curve in economics determines the price at which the good or service will sell. The demand curve is a downward sloping curve showing a negative relationship between the quantity and price. As the price increases, the quantity demanded will decrease as the buyers have to pay more for that particular good or service and vice versa. The supply curve is positively related to price. As

GE-Two -Decade Transformation Case Study Example | Topics and Well Written Essays - 1000 words

GE-Two -Decade Transformation - Case Study Example However, the company has in the past encountered severe challenges before attaining its current global position. In the late 20th century, the company encountered challenges which threatened its operations and stability. This paper will examine GE, discussing strategies employed by the company’s management in the wake of severe challenges. Welch’s Challenge in 1981 In the year 1981, when Welch took over management of GE from Jones, the company experienced numerous of hardships that threatened its existence. In 1981, the US economy suffered serious recession, which meant that banks lent money at unbelievably high interest rates. The high interest rates were especially disadvantageous to companies such as GE that required borrowed capital to sustain its business. In addition, the US dollar was quite strong at the time making GE’s international business operations quite unprofitable and unmanageable. The tough economic times experienced in the US also meant that GE had to lay off some of its employees and reduce hourly positions (O’Boyle, 1999). This put Welch and the company in a tough position, having to balance the company’s operations among the few remaining employees. Moreover, GE faced serious competition, particularly from Japanese companies. Global competitors had significant competitive advantages over GE as their nations of domicile were free of economic crisis like the US. However, despite the immense challenges, Welch was able to take charge of the company rather effectively through the adoption of numerous strategies. Welch first adopted the number one or two, fix, sell or close strategy that required all GE’s business units to be leaders in their respective industries or face closure. This strategy was effective in eliminating unproductive units of GE and strengthening the remaining units, which became leaders in their industries. The closure and sale of unproductive units provided necessary capital for produ ctive units to strengthen their operations. Welch’s strategy was effectual as it freed capital for strategic investments, which enhanced the company’s bottom line performance (Slater, 1998). Welch’s Objectives and Initiatives When Welch became the CEO of GE in 1981, he established the new company objectives to leverage GE’s performance within the company’s diverse business portfolio. In order to do this, Welch required all company employees to become â€Å"better than the best† in their positions and responsibilities (O’Boyle, 1999). In order to ensure the company achieved Welch’s objectives, the CEO initiated a series of strategies between the late 1980s and early 1990s. These initiatives centered on the spectrum of achieving organizational change through restructuring its staffing, layering and size. Through the adoption of the initiatives and strategic change, GE was able to achieve substantial competitive advantage within i ts markets. Welch’s initiatives were able to revitalize the company’s operations, bolster its image, and achieve massive profit margins. Welch streamlined the company’s staffing, especially in the company’s planning unit to ensure GE was lean and agile. The logic behind Welch’s de-staffing initiative centered on the notion that company or unit productivity does not rely on the number of staff in the unit, but rather the value each staff adds to the unit or company. Welch sought to instill the culture of strength in value addition

Minor injury and Illness Assessment in the Community

Minor injury and Illness Assessment in the Community Rebecca Bastow In the following assignment I am going to analyse and evaluate a case of Acute Otitis Media shown in appendix one, by discussing the pathophysiology behind this condition and how important the role of history-taking is as well as, the clinical presentation and the probable examination findings. To further support my findings of the condition I am going to including the special tests that are needed to confirm my diagnosis. Through the utilisation of appropriate evidence, I am going to justify and formulate my treatment plan and referral pathway, taking into consideration the ethical, medico-legal and professional responsibilities relating to the case. Acute otitis media (AOM) can be referred to as the presence of inflammation in the middle ear with possible effusion, its associated signs and symptoms are rapid in onset (Munir and Clarke, 2013, p. 27). It is evidenced that more than seventy-five percent of cases commonly affects young children under the age of ten, particularly those who are effected by passive smoking, attend nursery and are formula-fed. It is said to have a greater prevalence in males than females (Edwards and Stillman, 2006, p. 129 -137). Consequently, children have a horizontal, less acute angle and shorter Eustachian tube which makes it easier for bacterial enter and more difficult for fluid to move. However, normally it is collapsed but opens with swallowing and positive pressure (Nair and Peate, 2013, p. 565 -566). The recurrence of this infection can cause serious complications such as hearing loss, tympanic membrane perforation, infrequently it can lead to mastoiditis, facial nerve paralysis, sinus thrombo sis, and meningitis (Kivi and Yu, 2016). The presentation in adults and older children is usually reported as earache whereas, young children they may rub and pull on their ear or may present generic symptoms such as fever, continual crying, poor feeding, cough and restlessness at night. Signs and symptoms that are common in AOM consist of red, cloudy or bulging tympanic membrane, pain, pyrexia, headache, tinnitus, nausea and vomiting, reduction in hearing, malaise and otalgia (National Institute for Health and Care Excellence, 2015). Eustachian tube is situated at the anterior wall of the middle ear to the lateral wall of the nasopharynx and therefore, anatomically connects to the throat and palatine tonsil. Thus, allowing the infection to effect anything that is located in the connected pathways. AOM is a common condition that can be triggered by upper respiratory tract infections (twenty-five percent) either via bacteria or viruses (Nair and Peate, 2015, p. 157). Commonly, it is a virus that is responsible for the infection and is usually self-limiting. Although, other inflammatory conditions can have similar outcomes. Inflammation of the nasopharynx can spread up to the medial end of the Eustachian tube, forming stasis which in turn changes the pressure in the middle ear, relative to ambient pressure (Johnson and Hill-Smith, 2012, p. 34 -35). This level of stasis can result in bacteria settling in the space of the middle ear via the straight pathway from the nasopharynx (Nair and Peate, 2013, p. 565 -566). The prominent causes are reflux, blowing something into a body cavity or aspiration. The bodys natural reaction to acute inflammatory responses is recognised as vasodilation, leukocyte invasion, exudation, phagocytosis and local immunological responses in the middle ear (Nair and Peate, 2015, p. 157). It is said that viral based infections that target and harm mucosal linings of the respiratory tract may assistance bacterias ability to become pathogenic in the nasopharynx, Eustachian tube and the middle ear cleft. Viral infections have been understood in regard to its part in the pathogenesis of AOM yet, it is still not understood what actual role they play (Waseem, M, 2016). Immunology activity can play a vital role in the occurrence of AOM and its results. The nasopharynx also has an important role in the development of AOM, its lymphoid tissues provide a form of protection against pathogens by obstructing their attachment to surfaces of the mucosa (National Institute for Health and Care Excellence, 2015). There are numerous medico-legal considerations to bear in mind in Annas case due to her only being sixteen years of age (appendix one). The fundamental issue is whether she has mental capacity, it is an act designed to protect those who may lack the mental capacity to make their own decisions on their care and treatment. Which applies to individuals aged sixteen and over (NHS Choices, 2015). Individuals have to be given help to make a decision themselves and the information should be in a format that they can understand easily. If someone makes what is believed to be an unwise decision, they should not be treated as lacking capacity. Treatment and care given to those who lack capacity should be the least restrictive of their rights and freedoms (GOV UK, 2005). Mental capacity is determined by if there is an impairment, disturbance in the function of their mind or brain, as a result of a condition, illness or other external influences. And by whether theses consequently make the indiv idual unable to make specific decisions when they have to. Individuals may lack capacity to make specific decisions but have the capacity to make others (Quality Care Commission, 2016). It can also fluctuate with time, they may lack capacity at one point in time, but may be able to make the same decision at a later point. To be deemed to have mental capacity they must, understand the information pertinent to the decision, retain the information and use the information in the process of making that decision (NHS Choices, 2015). The capacity to consent to treatment has a controversial stance in under sixteen year olds. However, Gillick competence expresses that any child under the age of sixteen can consent, if they have sufficient understanding and intelligence to be capable of making a decision when required (Ministry of Ethics, 2014). This refers to the assessment undertaken by doctors to establish if a child under sixteen is deemed to have to capacity to consent for treatment in the absence of parental or guardian consent. The routine assessment of competence should be suitable for the childs age (NHS Choices, 2016). It could be argued, what is deemed to have sufficient for understanding and intelligence. In Annas case this does not directly apply because she is over that age nonetheless, the transferability is feasible. Children sixteen and over are deemed to have capacity by law and can consent or refuse treatment. If a child sixteen or over is believed to lack capacity, an assessment of capacity to consent needs to be carried out and documented (Quality Care Commission, 2016). Once valid consent to treatment has been attained it should be recorded as evidence, valid consent is where the medical professional has given the child, parents or both the applicable information about the purpose of treatment, as well as risks and possible alternatives (Department of Health, 2009). It is still good practice to provide parents with information however, consent needs to be sought from the child and the extent of information shared should be deliberated (Quality Care Commission, 2016). In regard to safeguarding concerns, information can be shared with parents without consent. Decisions made in the best interest for the individual, regarding care and treatment can be made anyone involved in caring for them, re latives, friends, and any attorney appointed (NHS Choices, 2016). As soon as I had consent from Anna or both Anna and her parents I would take a detailed history from her such as, when the pain started, pain score, characteristics of the pain, whether it is radiating anywhere, any allergies, medical conditions, current medication and social factors (appendix one). A thorough history is critical as it helps establish; potential treatment plans, possible safety netting features, rules out red flags or differential diagnosis (appendix two) which are all grounded on the findings from the physical assessment and special tests (Kavanagh, S, 2015). From observation, examination and palpation; it was recognised that her tonsils red and swollen, her head was inclined to right but was walking normally, otoscopy reviled that the tympanic membrane was cloudy and bulging slightly and her palatine and pre-auricle lymph nodes appeared tender (Douglas et al, 2013, p. 297 -314). The baseline observations showed that she had no significant temperature and all others observations were with normal parameters (appendix one). To support my diagnosis and exclude potential red flags indefinitely I would carry out some special auditory tests. The first type of hearing loss is conductive; this is a problem conducting sound waves along the path of the ear. It can occur anywhere from the outer ear, middle ear or, tympanic membrane (Munir and Clarke, 2013, p. 11). Sensorineural is the other type of hearing loss, in which the cause is situated in the inner ear, the cochlea or in the vestibulocochlear nerve (cranial nerve VIII), (Munir and Clarke, 2013, p. 11). A simple test to establish the level of hearing loss is the Voice test. By observing and engaging in conversation with the patient it is easy to recognise if you need to raise your voice to be heard clearly. A whisper test would help you gain greater perception of their hearing loss (Munir and Clarke, 2013, p. 13). A more complex and effective test that is greatly used is the Tuning fork test (Burkey et al, 1998). Within this there is two further tests, the first is called the Weber test (appendix three). This is where the tuning fork is hit on a surface to make it vibrate, then the base is placed on the middle of the patients forehead and then ask the patient where they hear this sound. It is normal for the patient to hear it in both ears except those with conductive hearing loss or unilateral sensorineural hearing loss, then it is better heard in one ear (Douglas et al, 2013, p. 303). The Rinnes test (appendix three) should conclude that the sound was louder beside the external aud itory meatus than on the mastoid process this is because air conduction is greater than bone (Rinnes positive), (Munir and Clarke, 2013, p. 13). This test is conducted by placing the vibrating fork on the mastoid process and then the patient reports when they can no longer hear it. The fork is then placed approximately two centimeters away from the external auditory meatus and asked if they can hear it, the patient then reports when they can no longer hear anything (Douglas et al, 2013, p. 303). However, if the patient informs you that the sound is louder on the mastoid process this means bone is the better conductor of sound (Rinnes negative) and applies to conductive deafness (Munir and Clarke, 2013, p. 13). A false negative Rinnes test can occur when hearing is very poor in one side, when the fork is placed on the mastoid process of the poor ear the sound can be conducted through the skull and projected to the good ear (Douglas et al, 2013, p. 303). To manage people with initial presentations of AOM paracetamol or a nonsteroidal anti-inflammatory drugs for instance, ibuprofen is used to treat pain and fever. It is evidenced that both of them are effective in relieving pain in children with AOM, and have few adverse effects when the suggested doses are used (Nair and Peate, 2015, p. 157). For the majority of people with AOM a non-antibiotic method is used, this is where they assure patients that antibiotics are not needed and that they make little difference to symptoms. Antibiotics may also have adverse effects and contribute to antibiotic resistance (Munir and Clarke, 2013, p. 23). A delayed antibiotic prescribing strategy could also be utilised, where they advise patients to commence antibiotics if within four days their symptoms do not improve or if they get substantially worse (Johnson and Hill-Smith, 2012, p. 34 -35). Immediate antibiotics should be given to people that have AOM and are; systemically unwell but admission is not needed, at the risk of complications due to existing diseases, those whose symptoms have continued for four or more days and not getting better, children under the age of two with infection in both ears and children with discharge in the canal or tympanic perforation (National Institute for Health and Care Excellence, 2015). A five-day co urse of amoxicillin is the first-line of treatment if antibiotics are required. Whereas, people that are allergic to penicillin have erythromycin or clarithromycin as alternatives (Munir and Clarke, 2013, p. 23). Amoxicillin is shown to be more effective than erythromycin or clarithromycin against the probable pathogens involved in AOM (National Institute for Health and Care Excellence, 2015). A Cochrane systematic review showed that was no respectable evidence for the routine use of antibiotics in the treatment of AOM in children (Venekamp et al, 2013). Although antibiotics showed to have a statistically significant decrease of children experiencing pain with AOM between day two and seven compared the placebo, eighty-two percent of the childrens symptoms spontaneously improved. It was concluded that the benefits and potential harms of antibiotic treatment must be evaluated, taking into account adverse effects and the possibility of resistance (Venekamp et al, 2013). However, the evidence exposed that they were the most effective against children under two with bilateral AOM, or with both discharge and AOM regardless of age. For the majority of children with mild AOM, an observational method seems acceptable (Venekamp et al, 2013). Another systematic review of the treatment of AOM in children found that compared with short course antibiotics, long courses reduced short-ter m treatment failure, but had no advantages in the longer term in comparison with short courses (Kozyrskyj et al, 2015). Consequently, to manage and treat Annas AOM I would treat her pain with paracetamol or ibuprofen taking into consideration of any allergies and her asthma. I would establish if she has taken ibuprofen before and whether there were any problems. The evidence above shows this condition to be self-limiting and that antibiotics have no significant effect in this condition. It is shown that the public have the most contact with the NHS via general practices, NHS England estimated that approximately one million people access their general practice each day (Comptroller and Auditor General, 2015). The number of direct and telephone contact with patients grew (15.4 percent) throughout all clinical staff in general practices between 2010 and 2015. During that period, the average patient list expanded by ten percent (Baird et al. 2016). It is evident that the non-emergency services like these are being sought by those with conditions that are not serious or life threatening. NHS Direct received roughly 4.4 million calls in 2011 and 2012, 2.7 million calls were made between 2012 and 2013 to NHS 111 and in 2007 and 2008, around 8.6 million calls were received by the GP out-of-hours services (National Institute for Health and Care Excellence. 2014). In Annas case of AOM it is evident that she is asymptomatic, the spread of infection has clearly tracked down from the nasopharynx, Eustachian tube, throat, tonsils to the palatine and pre-auricle lymph nodes. It directly corresponds with the physical assessment and the initial history of the conditions presentation therefore, ruling out a differential diagnosis. The no antibiotic framework above is evidently effective, I have concluded that an analgesic (paracetamol) or nonsteroidal anti-inflammatory (ibuprofen) approach would be adapted and advised to manage Annas pain. This also demonstrates the importance of history taking as Anna has only had these symptoms for two days, indicating that this treatment is the most appropriate. It is apparent that Anna does not require hospitalisation so I would need to leave her with the appropriate safety netting in place. Thus, if she was at home or at school when the incident occurred and her parents or teacher were present and content with mo nitoring her, I would leave the same advice as shown above. I would also advice Anna to go and see her GP if her symptoms worsen or persist for four or more days. It is documented that general practices are well-versed in the management of these non-urgent conditions if they develop or worsen. Similarly, it is evidence that the public are aware of which service to pursue if they experience any similar acute conditions. These actions would only be taken once the red flags were ruled out through the tests and assessments conducted above. In summary acute otitis media is usually a self-limiting condition that resolves by itself without the input of antibiotics subsequently, it is likely that Anna will not need any further involvement form any other healthcare professional.

In analyse and evaluate the case by discussing the pathophysiology of the condition and how this relates to the history-taking, clinical presentation and likely examination findings, including any special tests that may be required to diagnose the condition. You should then formulate a treatment plan and referral decision justified by critical analysis, taking the ethical, medico-legal and professional responsibilities of the case into account. Appendix 2 Differential Diagnosis of Otitis media Disease/Condition Differentiating Signs/Symptoms Differentiating Tests Otitis media with effusion Typically, the middle ear effusion is asymptomatic. On otoscopy these patients have an effusion of any color, air fluid levels, or bubbles with normal tympanic membrane landmarks. Myringitis These patients may have no symptoms attributable to the middle ear. On otoscopy there is erythema and injection of the tympanic membrane in the neutral position without other features of otitis media Mastoiditis There is edema, erythema, and tenderness over the mastoid process. Diagnosis is clinical based on history and examination. A CT scan may be warranted if symptoms are severe (to exclude abscess formation) or if the diagnosis is uncertain. Cholesteatoma Patients may present with painless otorrhea and hearing loss. Opacification of the tympanic membrane may lead to a misdiagnosis of AOM. Diagnosis is based on the history and clinical findings. Imaging is rarely necessary. (2017). Differential Diagnosis.
