Metaphor: (Kirszner, Mandell, 2012 p. 208) is a comparison using a particular concept to describe an abstract idea. For example, I told my father who is a comedian to go on stage and break a leg. Although that was said, it was not meant to be taking literally. Simile: (Kirszner, Mandell, 2012 p.208) is a comparison of two objects using the words like or as to make a comparison.

The Causes Of Segregation - 1472 Words

One of the biggest problems in the world is segregation, which is something that not everyone talks about. There are programs, clubs, billboards, and propaganda that try to send a message to society about segregation. But are people really listening? To me segregation means to make certain groups, and divide them because of their differences. When I hear the word segregation, I automatically think of race, because that is societies bias makes people think. Many people think that each race has to follow their own culture, and I do not agree with that.

The Government did not include African-Americans, and other colored people in the com munities, instead they were pushed into urban housing projects. I do not agree with this because there was been many laws that prevents and â€Å"eliminated† division of people. The FHA was in a project of mass-producing entire subdivision for whites, and the only requirements was to not sell any of the homes or any homes near the new houses to black people or else their loans would be in risk. In the New Deal, the Federal government made maps of color-coded. The map indicated where it was saf to insure mortgages and anywhere where African-Americans lived, which was colored red to indicate the neighborhoods that were too risky to insure mortgages. Some African-American families were able to buy the homes, but were prohibited to by the FHA. Now in day, the houses would cost as minimal as $300,000-$400,000. Later in the 1968, the FHA let’s African-American families buy homes in Daly City or Levittown, but no families would because the houses were no longer affordable .

Causes of the Civil War Essay Example For Students

Causes of the Civil War Essay Rhys Arnott The American Civil War is one of the most significant and controversial periods in American history. The Civil War was caused by mounting conflicting pressures, principles, and prejudices, fueled by differences and pride, and set into motion by unlikely set of political events. At the root of all of the problems was the establishment of slavery, which had been introduced into North America in early colonial times. The American Revolution had been fought to confirm the idea that all men were created equal, yet slavery was legal in all of the thirteen colonies throughout the revolutionary period. Although it was largely gone from the northern states by 1787, it was still enshrined in the new Constitution of the United States, not only at the request of the Southern ones, but also with the approval of many of the Northern delegates who saw that there was still much money to be made in the slave trade by the Yankee shipping industry. Eventually its existence came to influence every aspect of American life. The Compromise included admitting California as a free state and interstate slave trade to be abolished which went in favour of the North. The Compromise also went with the South when it included stricter fugitive slave laws and New Mexico and Utah were created without slave restrictions. A book called, â€Å"Uncle Toms Cabin† was also published at this time emphasising the evils of slavery. This added tension between the North and the South. The compromises seemed to have settled the issue of slavery but it was just putting back the problem. The North and the South were far from settling the slave issue. Another reason that caused the South to go to war was the difference in economic policies. The North was expanding more in the commercial and industrial side while the South was reliant on agriculture. Cities and factories had developed in the North and in the South, it was still staple-producing and agrarian. The Norths industry was beginning to dominate its economy while the South was still mainly based on agriculture. The South only produced manufactured goods for consumption and the North were able to export manufactured goods. The taxes and tariff was unfair to the South. The Tariff Act of 1832 put high import fees on all European manufactured good which was established to protect the Northern industries. The Souths reaction to the Act was a threat to secede from the Union. Railroads were also built to bond the northern tier of states. This made transportation easier in the Northeast than in the South. The Northeast traded with the West while the South can trade only by sea. â€Å"(W)antto promote the industry of the New England states, at the expense of the people of the South and their industry† In politics, the North had an advantage over the South. The North was more populated than the South and the South only counted slaves which was big part of their populations as * of a person. Since the House of Representative was based on population representation, the increasing population in the North gave them a big majority over the South. In the North, they strongly believe that majority rules and that they should make and execute the laws. This can be seen in the Lincoln-Douglas election when they were the favourites in the election. They are both from the North and the South wanted Douglas to win because he was for popular sovereignty. In the end, Lincoln won because the democratic party was split up and the Southerners was just outnumbered. La Haine Review Essay There were good reasons that the South entered the war. The North had been going over the line, trying to take away their state rights. The South had to stand up for themselves and fight for their moral rights. The South which was dependent on slavery would have been devastated if slavery was abolished. The prospering North was trying to control most of the South for their own capital benefits. This war was not fought on the institution of slavery but on maintaining the Southern civilisation.

The Significance of Colonialism Essay Example

The Significance of Colonialism Essay Whether it is all consuming character of Prospero, the vainglorious superiority of the Utopians or the savage greed of the first English Virginian colonists; there is a common will exercised in these three literary texts: conquer and take all. It is my aim in this essay to prove how an underlying theme of colonialism is being operated and advocated in these three texts, as a means of the progression and enrichment of a society specifically European and even more specifically white and English. To attempt to discuss the discourse of colonialism in these texts, it is important to locate them in the historical and political climate of the time. During the late 16th and early 17th centuries, England was experiencing a vast array of problems, both internally and externally. The foremost of these were a private-enterprise seaborne war against Spain (James 5), and a litany of potentially subversive Catholics resident within England itself and of course the newly acquired issue of overpopulation. An influential group of English courtiers and councillors, including the Earl of Leicester, Sir Francis Walsingham and Sir Walter Raleigh, (James 5) saw the vision of an expansionist Empire across the sea in the New World as the solution to many of these difficulties. Many plays, pamphlets and images were circulated which accorded with these aspirations.

(Wilson 333). Utopia is said to be inspired by accounts of the communistic way of life observed in some of these new found lands, although it is an imaginary world whose backbone is based upon slavery. Needless to say, Utopia seems to have inspired some of the ideology behind the concept of colonialism during this era, such as this portion from the play Eastwood Ho, which was written by George Chapman, Ben Jonson and John Marston and first performed in London during the summer of 1605. In this fragment, Captain Seagull describes th e wealth of the Virginian Indians: Why, man, all their dripping pans and their chamber pots are pure gold: and all the chains, with which they chain up their streets, are massy gold; all the prisoners they take are fettered in gold; and for rubies and diamonds, they go forth on holidays and gather em by the seashore, to hang on their childrens coats. (James 4) This description bears an uncanny resemblance to the Utopians treatment of gold, written by More almost a century earlier, and proves that Utopia contributed greatly to the adventurous beliefs associated with these new lands across the ocean. they make their chamber pots and close-stools of gold and silverof the same metals they likewise make chains and fetters for their slavesThey find pearls on their coast, and diamonds and carbuncles on their rocks; they do not look after them, but, if they find them by chance, they polish them, and with them they adorn their children (More 25) A Map of Virginia (Virginia) was written by John Smith as a promotional literary piece to encourage new settlers to the Virginia colony, for al is open for labor of a good and wise inhabitant (Smith 80). It is a historical, anthropological and geographical piece of literature which details the people and the commodities of the region and how those commodities may be used and made profitable. Consequently it is evident that a theme of colonialism is deep rooted in these texts, as Tmp and Virginia were written at the epicentre of the expansionist age, and Utopia written at the dawn of this era, when news of these new lands and peoples as just beginning to reach English shores and a dream of an empire was being pondered upon. It is interesting to note that the word colony comes from the Roman colonia which meant farm or settlement, and referred to Romans who settled in other lands but still retained their citizenship (Loomba Colonialism 7). In Tmp, Prospero is ousted from his dukedom of Milan and arrives on the island on which the play is set and sets up his own colonia on the isle, after expropriating it from its previous owner, the poisonous slave (Shakespeare 1.2.319), Caliban. This subjugation of Caliban, is justified by Prospero due to the tyranny of his mother, thy wicked dam (Shakespeare 1.2.320) Sycorax and to his innate savage behaviour, on whose nature / Nuture can never stick (Shakespeare 4.1.188-9). Although when Prospero first arrived on the isle, relations were quite cordial between the two, as Caliban recounts: When thou camst first, / Thou strokst me and made much of me ; wouldst give me / Water with berries int, and teach me how / To name the bigger light and how the less and then I loved thee, / And showed thee all the qualities othisleCursed be that I did so! (Shakespeare 1.2.332-339) Prospero masked his dependence on Caliban for information about the island with displays of physical affectionOnce petted, Caliban now remains penned like a pig, but on a rock barren of all food. Tales of initial native hospitality and sharing of fold and resources were stock-in-trade of English colonisers (Seed 203). Similarly, in Virginia, initial relations were positive, with regards to the relationship between that of John Smith and the Powhatan tribe of Amerindians. When the colonists first arrived in the Cheapeseake Bay area, the people in al parts kindly intreated them (Smith 31/32), and even after some disorder between the two groups, so moved are the Indians by the suffering that the starving colonists are enduring that they even share their corn with them: God the patron of all good indeavours in that desperate extreamity so cha~ged the harts of the Salvages, that they brought such plenty of their fruits, and provision as no man wanted. (Smith 35) After Smith is captured by the Powhatans, he manages to mesmerise them with his knowledge of science and geography, and in doing so is able to trick them into believing that he and his associates are of a superior power to them and come in friendship. This is reminiscent of the way that Prospero once loved and petted Caliban, teaching him how to name the bigger light and how the less burn by day and night. So he had incha~ted those poore soules (being their prisoner) in demonstrating vnto them the roundnesse of the world, the course of the moone and stares, the cause of day and night the largenes of the seas the qualities of our ships, shot and powder, The devision of the world, with the diversity of people, their complexions, customes and conditions. All which he fained to be vnder the command of Captaine Newport, whom he tearmed to them his father. (Smith 16-17 (38)) Prospero and John Smith use their knowledge to gain control over the dominions that they seek to conquer. Prospero has an aide in the spirit Ariel, who can subject the poor Caliban to endure tremendous pain and torments: Thou shalt have cramps,/ Side-stitches that shall pen thy breath up. Urchins/ Shall, for that vast of night that they make thy work, / All excercise on thee. Thou shalt be pinched / As thick as honeycomb, each pinch more stinging / Than bees that made em. (Shakespeare 1.2.325-330)) One of the ways that Prospero marks out Caliban as inferior is by his physical appearance. He is described as a freckled whelp, hag-born-not honoured with a human shape. (Shakespeare 1.2.283-284), and later in Act 2 Trinculo arrives on the island and encountering Caliban, gives a description of his appearance: What have we here-a man or a fish?A strange fish ! Were I in England now, as once I was, and / had but this fish painted, not a holiday-fool there but would give a piece of silver. There would this monster make a man-any strange beast there makes a man. / When they will not give a doit to relieve a lame beggar, they will lay out ten to see a dead Indian. Legged like a man, and his fins like arms! (Shakespeare 2.2.24-34). What Trinculo could possibly be making reference to here is to the possibility that Indians who died in England could have possibly been embalmed, clad in their indigenous attire and put on show for paying audiences, as no records attest to the departure or burial of more than a dozen Amerindians whose presence in England during Shakespeares lifetime is certain (Vaughan 58-59). Calibans subjugation is also justified because he is the spawn of a wicked dam (Shakespeare 1.2.320), the foul witch Sycorax (Shakespeare 1.2.257). There is no doubt that Sycorax was an African woman, as Prospero outlines her banishment from Algiers by the king of Tunis. Sycorax is branded as inferior due to her blackness, her female gender and then finally for the black arts that she practised and did harm with. The magical power that Prospero holds never comes into question for he is a white male and even though his sorcery too is evil and causes harm, he is protected by the colonial hegemony he has establis hed upon the island. Thus Prospero establishes a colonial power which is specifically white and male. He goes to great pains to enroot this belief by reminding the spirit Ariel of the cruel life enforced upon him by the islands old queen: This damned witch Sycorax, / For mischiefs manifold and sorceries terrible / To enter human hearing, from Algiers / Thou knowst was banished-for one thing she did / They would not take her lifeThou, my slave, / As thou reportst thyself, was then her servant,Refusing her grand hests, she did confine theeInto a cloven pine (Shakespeare 1.2.264-277). Prospero sees himself as superior and therefore reasonable in his enslavement of Caliban; because of Calibans assumed physical defects, his lineage from the corrupt witch Sycorax and his uncivilised behaviour. Prospero has confined Caliban on the hard rock (Shakespeare 1.2.343) because of an unsuccessful attempt to rape Miranda, but previous to this act, Prospero and Miranda had attempted to educate and civilise Caliban with disappointing results. Abhorred slave, / Which any print of goodness wilt not take, / Being capable of all ill! I pitied thee, / Took pains to make thee speak, taught thee each hour but wouldst gabble like / A thing most brutish But thy vile race- / Though thou didst learn-had that int which good natures / Could not abide to be with ; therefore wast thou / Deservedly confined into this rock, / Who hadst deserved more than a prison. (Shakespeare 1.2.350-361). Caliban is a failure at learning properly the language that Miranda has gone to such great pains to teach him. Prospero once even once lodged thee/ In mine own cell, till thou didst seek to violate / The honour of my child (Shakespeare 1.2.346-348). Miranda teaches Caliban language with the intention of conscripting him within the project of moral renewal but his wicked deed culminates in him being dispossessed and driven from her presence (Gillies The Figure 194). Calibans fall is reminiscent of Aristotles theory of the natural slave; unable to learn a language succinctly and incapable of bridling his sexual desires, Calibans punishment is a lifetime of servitude and shame. Thus his failure at education and misdemeanour provides Prospero with rationale for the expropriation and enslavement of Caliban. Patriarchal colonial rule is established upon the isle with Prospero as supreme head of state; protecting his pure, virginal daughter (even though she is quite capable of uttering a pr ofanity herself) from the unchecked carnal desires of the deformed Caliban. This preoccupation with preventing sexual connections (or even the threat of such contact) between English women and native men (Seed 211), has proven itself to be an enduring characteristic of many British colonies, where it has often been used the reasoning behind many cruelties and displays of violence (Seed 211). Something that would have resonated with Shakespearean audiences who watched this play were the many images circulating during this time, depicting the Sceptred isle as full and the New World as empty (Seed 205) as English colonists wanted to begin peopling the excess English population into this new territory; a concept which resonates with The Tempest during Calibans speech upon his failed attempt of raping Miranda and therefore unable to realise his dream: Thou didst prevent me-I had peopled else/ This isle with Calibans. (Shakespeare 1.2.348-349) In Virginia, special attention is also paid to the physical appearance and habits of the native Indians. He describes their attire as being assembled in a rude manner and the natives are viewed in subhuman, animalistic terms. In describing the character of the Powhatan tribe, Smith writes: Some are of disposition fearefull, some bold, most cautelous, all SavageThey are soone moved to anger, and so malitious, that they seldom forget an injury (37). (A stark contrast to Smiths description of them as seeming of an honest simple disposition earlier in the text). Smith accuses the Indians of child sacrifice, and of executing a fellow colonist, George Cassen, of a most merciless and cruel method of death (de-jointing a victim, then disembowelling him, finally setting him alight while being bound to a tree throughout the entire ordeal). Although these situations could have possibly occurred, he has evidence to support neither of them. Both accounts are merely hearsay, are hardly objective and obviously entered with the desired effect of swaying the judgment of the reader to thinking of the engrained savage nature of these Indians. There are many other tirades launched against the Indians (despite them saving the colonists from starvation out of compassion) but the cornerstone of his argument for civilising them is their religion, as Smith outlines their Chiefe God they worship is the Diuell. Him they call Oke serve him more of feare then loue. Smith writing this during a period of extreme religious piety in England and the actuality that the majority of the first colonists were God fearing Puritans, highlights the point that Smith was trying to make that these Indians were heathens and to colonise and therefore civilise them was Gods will. And end to the high glory of God, to the erecting of true religion among Infidells, to the overthrow of superstition and idolatrie, to the winning of many thousands of wandering sheepe, vnto Christs foldhave strayed in unknowne paths of Paginisme, Idolatrie and superstition (Smith ?). These new aims that claimed by Smith and his followers are quite different from the aims that Smith acknowledged the Virginia Company had outlined for them as to discover the country, subdue the people, bring them to be tractable, civil and industrious, and teach them trades, that the fruits of their labours might make vs recompence, or plant such colonies of our own that must (Smith ?). The use of religion as a means of suppression advocated by Machiavelli years before hand; he himself having traced the idea back to the foundation of the Roman Empire, when Romuluss successor, Numa Pompilius, finding a very savage people, and wishing to reduce them to civil obedience by the arts of peace, had to recourse to religion as the most necessary and assured support of any civil society (Greenblatt 20). The Virginia colonists aspirations to introduce the Indians to Christianity seem to be very suspicious especially when one considers the occasion when Smith fooled the Indians into thinking he was of a status of a demigod; capable of raising the poor Indian boy from the dead once his brother swore never to steal again. Even though Smith portrayed himself as a staunch Christian and as outlined previously stated that he wanted to bring an end to Paginisme, Idolatrie and Superstition, he exploited the superstitions of the Indians. The Indian king, Powhatan, asked Smith, what will it availe you, to take that perforce, you may quietly have with loue, or to destroy them that provide you food? (Smith). Powhatan was completely aware of the Virginia Companys true intentions, and there was very little Christian compassion and love engrained in them. Like Prospero, once Smith had gotten the information that he needed in order for James Town to prosper, he required a valid reason to force the Indians into submission, for as he said, For we haue a rule to finde beyond your knowledge (Smith). The Utopians, on the other hand, have already mastered the art of subduing and colonising, for although they do not hasten to go into war; when they do, they totally vanquish the enemy. Firstly, they do not use their own men in the war but employ a mercenary army of a neighbouring tribe, the Zapolets, who are a rude, wild and fierce nation, who delight in the woods and rocks, among which they were born and bred up. They are hardened both against heat, cold and labour, and know nothing of the delicacies of life (More 39). Once the Utopians have struck down their enemies and entered into their lands, they never lay their enemies country waste nor burn their corn, and even in their marches they take all possible care that neither horse nor foot may tread it down, for they do not know but that they may have use for it themselves (More 41). The use that they make of these newly conquered lands is to establish somewhat a form of a colony, extracting taxes from the occupied country. When a war is ended, they do not oblige their friends to reimburse their expenses; but they obtain them of the conquered, either in moneyor in lands, out of which a constant revenue is to be paid themThey send some of their own people to receive these revenues, who have orders to live magnificently, and like princes, by which means they consume much of it upon the place; and either bring over the rest to Utopia, or lend it to that nation in which it lies. (More 41). In Utopia, the whole foundation of their civilisation has been founded upon conquest and colonisation. For as their history records: Utopus that conquered it (whose name it still carries, for Abraxa was its first name) brought the rude and uncivilized inhabitants into such a good government, and to that measure of politeness, that they now far excel all the rest of mankind (More 17). The Utopians regard slavery as a normal part of their culture, and similar to Prosperos chastisement of Caliban, use it as the punishment even of the greatest crimes; for as that is no less terrible to the criminals themselves than death, so they think the preserving them in a state of servitude is more for the interest of the commonwealth than killing them; since as their labour is a greater benefit to the public than their death could be, so the sight of their misery is a more lasting terror to other men than that which would be given by their death. If their slaves rebel, and will not bear their yoke and submit to the labour that is enjoined them, they are treated as wild beasts that cannot be kept in order, neither by a prison nor by their chains, and are at last put to death. (More 35). Another sort of slaves are the poor of the neighbouring countries, who offer of their own accord to come and serve them; they treat these better, and use them in all other respects as well as their own countrymen, except their imposing more labour upon them, which is no hard task to those that have been accustomed to it. (More 33). A form of communal living presides in the countryside, people living together in country families, which consist of no fewer than forty men and women in it, besides two slaves (More 17). All of the most menial and unpleasant tasks of Utopian life are performed by these slaves, such as the slaughter and butchering of animals, for they suffer none of their citizens to kill their cattle, because they think that pity and good natureare impaired by the butchering of animals. (More 23). The Utopians regard themselves as morally and intellectually superior to these slaves, but due to their love of education, take it upon themselves to redeem these slaves through knowledge and pestilence.

Lightweight Strong Materials In A Composite Surfboard

Lightweight Strong Materials In A Composite Surfboard The composite surfboard is a common place in the sport today. Ever since the introduction of fiberglass composites after World War II, the surfboard industry was truly one of the first to embrace composites. Prior to fiber reinforced composites, surfboards were manufactured out of wood and could weigh over 100 lbs. Today, a composite surfboard the same size (10 feet) might weigh less then 10 lbs. To shed this enormous amount of weight, surfboards took advantage of 3 key materials: Foam Core Polyurethane foam became the core material of choice for surfboards. It is lightweight, provides thickness, and provides buoyancy. The foam core of a composite surfboard is sandwiched between FRP skins and creates the stiffness and structure of the surfboard. Often, a stringer of wood is bonded in the center of the board to provide increased rigidity, much like an I-beam. The surfboard foam industry was dominated by the company Clark Foam up until 2005, at which time the owner decided to shut down with no prior warning. Today, the foam core for composite surfboards is primarily polyurethane foam. However, expanded polystyrene (EPS) is being used more often as the use of epoxy resins increases. Regardless of the foam used it almost always closed-cell, so that it does not absorb moisture. Resin Thermosetting resins have been key to the success of the composite surfboard. Even when boards were made of wood, resins and coatings were used to help prevent the boards soaking in water. As resin technology continues to improve, boards are able to become stronger and lighter weight. The most common resins used in composite surfboards are polyester resins. This is primarily because polyester resin is inexpensive. Additionally, resin manufacturers have perfected their polyester surfboard resins so that they are easy to work with and are crystal clear. It is important that the resins used are water-clear, because a surfboard is as much a work of art as it is a functional piece of equipment. As surfboards age, they turn yellow from the UV rays. Hence, UV resistance is an important factor to the resins used today. With the advancements in resin technology, it is no surprise composite surfboards are being manufactured with epoxy. Epoxy has no VOC emissions during the manufacturing process, and it has much higher strength, fatigue, and impact resistance properties. However, the only current downside to using epoxy is, these boards tend to turn yellow faster then polyester boards. Although, this may soon change with improved formulations. Fiberglass Fiberglass is the structural backbone to surfboards. The fiberglass reinforcement provides the structure and strength to the board. Most commonly, lightweight woven fiberglass cloth is used as the reinforcement. Usually, it is between 4 and 8 ounce fabric. (Ounces per square yard). Often more then one layer is used. Currently, the weaves used are evenly balanced with equal amounts of fiberglass running from nose to tail, and rail to rail. However, engineers are designing boards with different amounts of fiber running in different directions. This provides the strength and the rigidity where required, without adding much additional weight. Future Of The Composite Surfboard Surfers are known for being progressive, and with this comes experimentation with different shapes and materials. Boards today are embracing composite technology and new materials. The composite surfboards of the future are incorporating fibers such as Kevlar, carbon fiber, and Innegra. The various properties of the many composite reinforcements available can allow the surfer or engineer, to tweak the properties to help create the dream board. It also makes a surfboard extremely cool looking to have unique materials and construction. The various properties of the many composite reinforcements available can allow the surfer or engineer, to tweak the properties to help create the ultimate surfboard. It also makes a surfboard extremely cool looking to have unique materials and construction. Not only are the materials being used changing, but the method of manufacturing is evolving as well. CNC machines are commonly being used to precisely machine out the foam core. This creates boards that are almost perfectly symmetrical and exact. At first, the fear of mass production brought concerns of removing the soul from the sport. Meaning, the traditional method of hand shaping boards is being reduced to the job of a computer. However, the opposite seems to be true. Custom boards, which are truly works of art, seem to be as popular as ever. And with composites, creativity in methods and materials to laminate boards seems to give an endless opportunity to customize and personalize boards. The future of the composite surfboard is bright. In the 1950s the use of fiberglass was revolutionary. The new pioneers will continue to push the envelope and will embrace the next generation of composite materials and processing techniques.

The Facts About Dry Ice

The Facts About Dry Ice Dry ice is the solid form of solid carbon dioxide, CO2. Here are some facts about dry ice that can help keep you safe when working with it- and are just fun to know. Dry Ice Facts Dry ice is solid carbon dioxide. It is sometimes called cardice.Dry ice is extremely cold (-109.3 °F or -78.5 °C). At this temperature, it sublimates from the solid state into the gaseous state or undergoes deposition from gas to solid. In order for dry ice to form liquid carbon dioxide, it needs to be placed in a high-pressure environment.The first published observation of dry ice was in 1835 by French chemist Charles Thilorier. He noted the formation of dry ice when a container of liquid carbon dioxide was opened.Dry ice resembles snow or water ice.  Its usually sold as chunks or pellets, which appear white because water vapor from the air readily freezes onto the surface. While it looks somewhat like ordinary water ice, its called dry because theres no intermediate liquid phase.Dry ice density usually ranges between 1.2 and 1.6 kg/dm3.The molecular weight of dry ice is 44.01 g/mole.Dry ice is nonpolar, with a dipole moment of zero. It has low thermal and electrical conductiv ity. The specific gravity of dry ice is 1.56 (water 1). Dry ice sinks in water and to the bottom of drinks.The white vapor released when dry ice sublimates does contain carbon dioxide, but its mostly water fog produced when the cool gas condenses water from the air.When dry ice is added to food, as when making ice cream or freezing fruit, the carbon dioxide carbonates the liquid and can react with water to form dilute carbonic acid. This adds an acidic or sour flavor.When dry ice sublimates, some of the carbon dioxide gas immediately mixes with air, but some of the cold dense gas sinks. Carbon dioxide concentrations increase near the floor of a room where a lot of dry ice is being used. Dry Ice Safety Contact with dry ice can result in frostbite and cold burns. Avoid allowing contact between dry ice and the skin, eyes, or mouth.Use insulated gloves when handling dry ice.Although dry ice and carbon dioxide are not toxic, the use of dry ice may present a respiratory hazard because it can sink and displace air near the ground. Also, when it mixes with the air, there is more carbon dioxide (less oxygen) in each breath. Use dry ice in a well-ventilated area.Do not eat or swallow dry ice.Do not seal dry ice in glass or other closed containers, since the pressure buildup may result in breakage or bursting.

The Chinese economy has maintained a momentum of rapid growth while Essay

The Chinese economy has maintained a momentum of rapid growth while many other economies in the world have slumped - Essay Example As a result, the barriers to economic growth under the conventional planned economy were removed and full production became the order of the day. As part of the economic reforms, the country adopted a step-by-step approach in pushing the reforms ahead. At the same time, it made sure that there as a balance between the economic reforms, growth and social stability. This enabled the country to correct the notion that China is a hard place to trade as is evidenced by the large capital investment by overseas investors. According to Sharma (2007), there has been a major capital injection into the country’s economy, which been a major boost in the development of the economy. The country has also recognized the importance of a flexible monetary exchange rate. It has put measures in place to ensure that there is free capital mobility (Prasad, 2004). Economic experts have argued that the high economic growth rate registered by China will only be sustained if the country continues imple menting the comprehensive economic reforms, and the open up policies. ... This has been enabled by the ongoing reforms in the banking sector. Financial transactions and mediations in China are transacted across the banking sector. The banking industry is heavily dominated by the state-owned banks who act as the main lender to companies in China. There is an absence of the corporate bond market which underscores the crucial role that banks play in the economy of China (Li, 1997). China has instituted a reduction in interest rates to encourage more borrowing especially by people in the private sector, particularly the small and medium enterprises. Therefore, stability of the banking industry in China is crucial for sustainability of economic growth in the country (Li, Liu and Yun, n.d.). Currently, the Chinese government has accelerated efforts to address three key issues; maintaining the economic growth, avoiding social contradictions and improving the ability to cope with financial crisis. Lams have been put in place to stimulate domestic demand with an ai m of reducing the over reliance on Gross Domestic Product growth in fixed investment and export promotion. China relies more on the export market which is detrimental in the midst of a global financial crisis like the one being experienced in the world (Wang, 2010). To address this issue of export-oriented economy, the Chinese government has made it a national strategy to strike a reasonable balance between the export oriented models and inward- looking economy. This is being implemented through expansion programs in the global market, while laying down policies to promote domestic consumptions. The Chinese government is on record for trying to uplift the purchasing power of its large

Eco Bus 2 Essay Example | Topics and Well Written Essays - 1000 words

Eco Bus 2 - Essay Example Income elasticity is a measurement of the rate over time of a change in quantity demanded because of a positive or negative change consumer income. As consumer income rises, if a good decreases in demand, it is an â€Å"inferior good†; if demand for a good rises proportionally to increases in consumer income, it is a â€Å"normal good.† 1. The elasticity of demand coefficient expresses how sensitive consumers are to changes in price. To avoid ambiguity, the coefficient of the elasticity of demand is expressed in an absolute value. While a zero quantity expresses perfect inelasticity (that is, quantity demanded is unaffected by changes in price), any value in between zero and one will represent relative inelasticity. A value that is greater than one will represent a relatively elastic demand, up until a value of infinity, which represents a perfectly elastic demand (that is, quantity demanded is infinitely changed by changes in price. An elasticity coefficient equal to negative one indicates unit-elastic demand, which is a situation that occurs when the percentage change in quantity demanded is equal to the percentage change in price. 2. The cross-price elasticity coefficient expresses how sensitive demand is to a price change of other related goods. Elasticity coefficients above zero indicate that there is a high inverse correlation between the prices of Good A and Good B, which means that the goods are substitutes. In contrast, coefficients below zero indicate direct correlations between the prices, which means those goods are complements. Small absolute values of the cross-price elasticity coefficient indicate that there is little or no relation between the prices. 3. The income elasticity coefficient expresses how sensitive demand for a good is to income change. Income elasticity coefficients below zero indicate that there is a strong direct correlation between income increasing (or decreasing) and demand for a good

David Livingstone Essay -- essays research papers

David Livingstone was one of the most revered and respected African explorers of his time. He spent almost 30 years exploring a region little known to the outside world. He often put ambition before family and his own personal health in his quest to open the interior of Africa to “Civilization, Christianity, and Commerce.';(Hollett 236) Through his daring explorations into the unknown, he discovered and documented many new landmarks inside the dark continent, and at times became obsessed with his determination to find a single source of the Nile. He had a major impact on later expeditions into central Africa. .   Ã‚  Ã‚  Ã‚  Ã‚   Livingstone was born to a poor Scottish family in 1813. Starting at age ten, Livingstone worked in a cotton mill while pursuing his studies at night. He was an avid reader, and would often stay up until twelve or later, buried in a book. Livingstone enjoyed reading on a variety of subjects, but read mostly scientific works and explorer’s journals. As a boy, David made few friends. Others described him as quiet, sulky, and unremarkable. Yet despite this, David was a tireless worker, and extremely motivated toward his goals.   Ã‚  Ã‚  Ã‚  Ã‚   By age 17, Livingstone had decided he wanted to leave the mill and become a doctor. Livingstone’s father, a deeply religious man, wanted him to go into a religious field, and would not allow him to go. Livingstone eventually convinced his father to let him go to school and become a missionary in China. After finishing school, Livingstone had planned to go to China to perform his missionary duties, but because of the Opium War, Livingstone’s plans were altered. He continued his studies, and became a respected member of the medical community. Soon though, he offered his services to the London Missionary Society, and was assigned to a mission in Africa.   Ã‚  Ã‚  Ã‚  Ã‚   Early knowledge and exploration of Africa was confined to desert and coastal regions. The interior humid regions held many difficulties for prospective explorers. This included climate, vegetation, and hostile peoples and creatures. Throughout the 18th and 19th centuries, most of Africa was unexplored, and unmapped. The British were the first Europeans to make a serious attempt at exploration of the interior of Africa. Earlier European contacts were rel... ...lf that the Lualaba River was the source of the Nile, it was not confirmed until after Livingstone’s death that Lake Victoria and the Mountains of the Moon were the actual sources of the Nile. Livingstone’s missions began and ended in Africa. His explorations were primarily in the Lake Tanganyika and Lualaba River regions. He enjoyed living with the native peoples, eating their food, sleeping in their huts, and without losing his own identity, he made their life his own. He probably understood the African people; their beliefs, fears and needs better than anyone outside of Africa at that time. He sacrificed personal needs for what he believed was his mission to Africa,and was probably more spiritually content to meet his death there than any place else. David Livingstone’s three works on South and South Central Africa had major impacts on the worlds understanding of, and social and political attitudes and policy towards Africa. Although his books made him one of the most famous and respected explorers, he was not as concerned with fame and riches as much as having the backing and resources to pursue his objectives in the then dark continent of Africa.

How does reflect through history, invention, society and the Arts? Essay

The unifying theme of this period is colonialism and emerging trends. This was the time where Napoleon Bonaparte gained so much power and recognition throughout the world whereas he was feared by men. In relation to invention, there were new great inventors like Alesssandro Volta for the battery, Jacquard Loom for calculator/computer, and Oliver Evans for the refrigerator. During this era, artists like Ludwig van Beethoven, Theodore Gericault, Alans Wordsworth and Jane Austen became famous. Their works are still known until today. A neoclassical architectural style also existed in this period. The Cathedral of Vilnius, conceptualized and put into existence by Laurynas Gucevicius, is an example. Neoclassical Architecture has some features that are the same with the Late Baroque architecture. However, its emphasis is its planar qualities, rather than sculptural volumes. Projections and recessions and their effects of light and shade are flatter; sculptural bas-reliefs are flatter and tend to be enframed in friezes, tablets or panels. Its clearly articulated individual features are isolated rather than interpenetrating, autonomous and complete in themselves. International neoclassical architecture was exemplified in Karl Friedrich Schinkel’s buildings, especially the Old Museum in Berlin, Sir John Soane’s Bank of England in London and the newly built White House and Capitol in Washington, DC in the United States. The Scots architect Charles Cameron created palatial Italianate interiors for the German-born Catherine II the Great in St. Petersburg. 2. In the early 1800’s, Australia was still a young colony. Who were the major Australian artistic figures of this period? (You might mention architects, writer, painters or musicians and their works. ) One of the major artistic figures in Australia during 1800s who gained recognition in this era was Norman Lindsay. He was the principal cartoonist of the Bulletin magazine. He was also one of the people who advocated their right to paint the nude. He also wrote novels but his major work consisted of pen drawings, etchings, watercolours and oil paintings, all of which are well represented at ‘Springwood’ (the Norman Lindsay Gallery & Museum). He also illustrated the cover for the seminal Henry Lawson book, â€Å"While the Billy Boils†. In the field of writing or literature, Henry Lawson was one of the major writers and poets during this period. Many believe he was the first poet to capture the Australian way of life. His works are still known and an inspiration to Australians. In architecture, Francis Howard Greenway was one of the major artistic figures. His work includes Hyde Park Barracks (1817-19), St Luke’s, Liverpool (1817-24), St James’s, Sydney (1819-22), St Matthew’s, Windsor (1819-22) and other extant buildings are now popularly appreciated as the foundations of Australian architecture. His picturesque Gothic buildings, on the other hand, are mostly long demolished and his ‘Turnpike Gate at Sydney with Gothic Lodge and Offices’ (1819-20), his designs for Sydney’s Anglican and Catholic cathedrals (the former never built, the latter much modified before its erection), even his (extant) Government House stables, have played little part in the creation of the Greenway architectural persona.

Quotes From Charles Dickenss Oliver Twist

Quotes From Charles Dickenss Oliver Twist Charles Dickens second novel, Oliver Twist, is the story of an orphan growing up among criminals in London, England. The novel, one of Dickenss most popular works, is known for its harsh depiction of poverty, child labor, and life in the London slums of the mid-19th century. Poverty Oliver Twist was published at a time when many of Dickenss countrymen were living in great poverty. The most unfortunate were sent to workhouses, where they received food and lodging in exchange for their labor. The protagonist of Dickenss novel ends up in such a workhouse as a child. To earn his gruel, Oliver spends his days picking oakum. Please, sir, I want some more. [Chapter 2] Oliver Twist has asked for more! [Chapter 2] I am very hungry and tired... I have walked a long way. I have been walking these seven days. [Chapter 8] Bleak, dark, and piercing cold, it was a night for the well-housed and fed to draw round the bright fire, and thank God they were at home; and for the homeless starving wretch to lay him down and die. Many hunger-worn outcasts close their eyes in our bare streets at such times, who, let their crimes have been what they may, can hardly open them in a more bitter world. [Chapter 23] Human Nature Dickens was admired not only as a novelist but also as a social critic, and in Oliver Twist he uses his sharp eye to dissect the weaknesses of human nature. The social canvas of the novel, which includes the poor underclass of London and the criminal justice system designed to contain it, allows Dickens to explore what happens when humans are reduced to the basest conditions. The doctor seemed especially troubled by the fact of the robbery having been unexpected, and attempted in the night-time; as if it were the established custom of gentlemen in the housebreaking way to transact business at noon, and to make an appointment, by the twopenny post, a day or two previous. [Chapter 7] Although Oliver had been brought up by philosophers, he was not theoretically acquainted with the beautiful axiom that self-preservation is the first law of nature. [Chapter 10] There is a passion for hunting something deeply implanted in the human breast. [Chapter 10] But death, fires, and burglary, make all men equals. [Chapter 28] Such is the influence which the condition of our own thoughts, exercises, even over the appearance of external objects. Men who look on nature, and their fellow-men, and cry that all is dark and gloomy, are in the right; but the sombre colours are reflections from their own jaundiced eyes and hearts. The real hues are delicate, and need a clearer vision. [Chapter 33] The suspense: the fearful, acute suspense: of standing idly by while the life of one we dearly love, is trembling in the balance; the racking thoughts that crowd upon the mind, and make the heart beat violently, and the breath come thick, by the force of the images they conjure up before it; the desperate anxiety  to be doing something  to relieve the pain, or lessen the danger, which we have no power to alleviate; the sinking of soul and spirit, which the sad remembrance of our helplessness produces; what tortures can equal these; what reflections of endeavours can, in the full tide and fever of the time, allay them! [Chapter 33] Society and Class As the story of a poor orphan, and of the downtrodden more generally, Oliver Twist is filled with Dickenss thoughts about the role of class in English society. The author is highly critical of the institutions that protect the upper classes while leaving the poor to starve and die. Throughout the book, Dickens raises questions about how society organizes itself and treats its worst-off members. Why everybody lets him alone enough, for the matter of that. Neither his father nor his mother will ever interfere with him. All his relations let him have his own way pretty well. [Chapter 5] I only know two sorts of boys. Mealy boys, and beef-faced boys. [Chapter 10] Dignity, and even holiness too, sometimes, are more questions of coat and waistcoat than some people imagine. [Chapter 37] We need be careful how we deal with those about us, when every death carries to some small circle of survivors, thoughts of so much omitted, and so little done- of so many things forgotten, and so many more which might have been repaired! There is no remorse so deep as that which is unavailing; if we would be spared its tortures, let us remember this, in time. [Chapter 8] The sun,the bright sun, that brings back, not light alone, but new life, and hope, and freshness to manburst upon the crowded city in clear and radiant glory. Through costly-coloured glass and paper-mended window, through cathedral dome and rotten crevice, it shed its equal ray.  [Chapter 46]

Vertical and Vertiginous

Vertical and Vertiginous Vertical and Vertiginous Vertical and Vertiginous By Simon Kewin A steep climb up a mountain is sometimes described as â€Å"vertiginous†, as in the following quotation from a description of a hike up the Inca Trail: You have time to make the vertiginous climb to its summit for dramatic views of the city spread out below. You might be excused for thinking that â€Å"vertiginous† is related to â€Å"vertical†, perhaps with the additional implication of being precarious and dangerous. In fact, the two words are from different roots and have quite distinct meanings. Vertical, which is the adjective form of the English noun vertex, comes originally from the identical Latin word vertex, meaning an eddy or a summit. A line is vertical if it rises to a vertex, perpendicular to the horizon. So, a vertical cliff is one that goes straight up from the ground. Vertiginous, meanwhile, means dizzying; it’s the adjectival form of the noun vertigo, meaning dizziness or giddiness. It derives from the Latin word vertigo, meaning whirling. So, an ascent would not have to be vertical in order to be vertiginous and, if you weren’t prone to vertigo, it could be vertical and not vertiginous. Some dictionaries suggest that the Latin words vertex and vertigo do share a common root : vertere, meaning to turn. It’s easy to see how vertiginous has evolved from this meaning, with its sense of dizzy whirling. Vertical, meanwhile, presumably derives because something could rotate around a vertical axis.

Tribute Money by Masaccio Essay Example | Topics and Well Written Essays - 500 words

Tribute Money by Masaccio - Essay Example Matthew, kneeling in the far left, deliberately replies strangers. The tax collectors confront the group of holy men. Masaccio’s purpose was to create a realistic painting that contained natural aspects of the environment as well as the human composition. He focuses on directing the viewer’s eyes to the vanishing point of the painting, the head of Christ. Masaccio used atmospheric perspective, making all the mountains in the background hazy and Peter to be paler than the figures in the foreground. This technique created a depth within the painting to render Realism. It is difficult to see the cuts of the mountains in the background but the folds of the robesin the foreground are easily distinguishable. Masaccio, unlike earlier artists like Giotto, did not use a flat, neutral light from an unidentifiable source. He used light from a specific location outside the painting to create a chiaroscuro effect, the representation of form through light and color without outlines. There is no light source visible within the picture but if the viewer notices the shadows of the figures, they are al l cast away from the chapel. This makes the viewer believe the figures were lit by the light through the chapel window. Masaccio proves this belief by creating the front two columns brighter than the rest of the chapel. Furthermore, the tax collector on the far right and the chapel wall is extremely dark. In general, all figures and objects become gradually dimmer as the viewer looks to the right. Masaccio uses the composition of his figures to create a three-dimensional world to depict reality. Masaccio’s figures in the foreground are large, solid figures that dominate the natural setting before the lake and mountains. In contrast, he uses soft hand gestures and facial expressions rather than swift actions to show movements within the painting. This emphasizes

Business Law Essay Example | Topics and Well Written Essays - 1000 words - 2

Business Law - Essay Example The primary concern of the questioner is whether his concern can be referred to the court. The other two concerns are: 1. Position of the concerned court with respect to end-of service gratuity for the previous period of the visa. 2. Salary difference of the actual received and mentioned in the labour contract. Response: Al Shaiba clarified about the right of questioner that he has full right to get compensation based on his actual employment duration which is three years. Regarding the salary difference, Labour Law calculates the compensation based on the current salary drawn by the employee. Therefore, both the concerns addressed clarify that the employee shall get his case referred under the concern court through the Ministry of Labour. Query#2: Gratuity Calculation The questioner worked in a company under unlimited contract for one year before tendering his resignation. Questioner has two queries: 1. The end of service gratuity was calculated on the basis of 21 days salary. 2. If the questioner is legally entitled for a return ticket to his home country as the contract was signed in the home country. Response: Al Shaiba gave the reference of Article No 137 of the Federal Labour Law No.8 of 1980. This article clarifies the doubt of the respondent. The article states, "Where a worker under an indefinite term contract abandons his work at his own initiative after a con ­tinuous service of not less than one year and not more than three years, he shall be entitled to one-third of the severance pay provided for in the preceding article. Such a worker shall be entitled to two thirds of the said severance pay if his continuous service exceeds three years up to five years and to the full severance pay if it exceeds five years". The second doubt is clarified that the employee is entitled to get the return tickets to home provided he returns back to home country and does not work with a new employer. Query 3: Arbitrary Dismissal This is a case of dismissal of an emp loyee who was working for his company from more than two years. The nature of the contract was for unlimited period. The employee received dismissal due to his absence from work for five consecutive days without excuse, 6th day he was present at work but again 7th and 8th day he went absent. The dismissal was justified under pursuant of the Article n. 120 (Labour Law) and employee was explained that he was not entitled to end-to service gratuity even after producing medical report for the absence period. The queries were: 1. Questioner wanted to know the Article 120 in detail. 2.

Business ethics take home exam - Coursework Example However then whichever constitution that permits authoritarianism requires it, and whichever constitution that necessitates non-dictatorship disagrees with one of the other requirements, therefore, the paradox of shared choice. The set of requirements across diverse likely votes polished welfare economics as well as differentiated Arrows establishment from the pre-Arrow shared welfare utility (Kavvadias 98-99). The original position as explained by Rawls entails at least two important elements of features.   Foremost, the original position is a condition in which people are rationally self concerned.   Next, the original position is a condition in which people are deficiency of all information exact to their ultimate lives.   This information deficiency stretches from personal factors like the deposit of natural endowments a person will be conceived with, to wide shared considerations of what locality, moment as well as culture a person will be conceived into (Rawls 29-35) The â€Å"Foremost Principle† addresses the fundamentals of the legitimate composition. It maintains that society should assure every inhabitant â€Å"the same claim to a completely sufficient plan of equal essential rights and freedoms, which plan is attuned with the same plan for all.† The second standard addresses rather those features of the fundamental construction that shape the allocation of opportunities, administrative centers, wages, material goods, and in overall social advantages. The initial part of the second standard maintains that the shared structures that shape this allocation must fulfill the conditions of â€Å"fair equity of opportunity† (Rawls 29-35). c. Rawls claims that a rational individual in the original position would choose the principles of justice as fairness over the principle of average utility. What is his reasoning to support the

Measures of Dispersion

Measures of Dispersion Summary The measure of central tendency, as discussed in the previous chapter tells us only about the characteristics of a particular series. They do not describe any thing on the observations or data entirely. In other wards, measures of central tendency do not tell any thing about the variations that exist in the data of a particular series. To make the concept, let discuss an example. It was found by using formula of mean that the average depth of a river is 6 feet. One cannot confidently enter into the river because in some places the depth may be 12 feet or it may have 3 feet. Thus this type of interpretation by using the measures of central tendency some times proves to be useless. Hence the measure of central tendency alone to measure the characteristics of a series of observations is not sufficient to draw a valid conclusion. With the central value one must know as to how the data is distributed. Different sets of data may have the same measures of central tendency but differ greatly in terms of variation. For this knowledge of central value is not enough to appreciate the nature of distribution of values. Thus there is the requirement of some additional measures along with the measures of central tendency which will describe the spread of the entire set of values along with the central value. One such measure is popularly called as dispersion or variation. The study of dispersion will enables us to know whether a series is homogeneous (where all the observations remains around the central value) or the observations is heterogeneous (there will be variations in the observations around the central value like 1, 50, 20, 28 etc., where the central value is 33). Hence it can be said that a measure of dispersion describes the spread or scattering of the individual values of a series around its central value. Experts opine different opinion on why the variations in a distribution are so important to consider? Following are some views on validity of the measure of dispersion: Measures of variation provide the researchers some additional information about the behaviour of the series along with the measures of central tendency. With this information one can judge the reliability of the value that is derived by using the measure of central tendency. If the data of the series are widely dispersed, the central location is less representatives of the data as a whole. On the other hand, when the data of a series is less dispersed, the central location is more representative to the entire series. In other wards, a high degree of variation would mean little uniformity whereas a low degree of variation would mean greater uniformity. When the data of a series are widely dispersed, it creates practical problems in executing data. Measure of dispersion helps in understanding and tackling the widely dispersed data. It facilitates to determine the nature and cause of variation in order to control the variation itself. Measures of variation enable comparison to be made of two or more series with regard to their variability. DEFINITION: Following are some definitions defined by different experts on measures of dispersion. L.R. Connor defines measures of dispersion as ‘dispersion is the measure extended to which individual items vary. Similarly, Brookes and Dick opines it as ‘dispersion or spread is the degree of the scatter or the variation of the variables about a central value. Robert H. Wessel defines it as ‘measures which indicate the spread of the values are called measures of dispersion. From all these definition it is clear that dispersion measures more or less describes the spread or scattering of the individual values of a series around its central value. METHODS OF MEASURING DISPERSION: Dispersion of a series of data can be calculated by using following four widely used methods Dispersion when measured on basis of the difference between two extreme values selected from a series of data. The two well known measures are The Range The Inter-quartile Range or Quartile Deviation Dispersion when measured on basis of average deviation from some measure of central tendency. The well known measures are The Mean/average deviation The Standard Deviation and The Coefficient of variation and The Gini coefficient and the Lorenz curve All the tools are discussed in details below one after the other. THE RANGE: The range is the simplest measure of the dispersion. The range is defined as the difference between the highest value and the lowest value of the series. Range as a measure of variation is having limited applicability. It is widely used for weather forecasting by the meteorological departments. It also used in statistical quality control. Range is a good indicator to measure the fluctuations in price change like that of studying the variations in the price of shares and debentures and other related matters. Following is the procedure of calculating range: Range= value of the highest observation (H) – value of the lowest observation (L) or Range = H – L Advantages of Range: Range is the simplest of obtaining dispersion. It is easily understandable and can be interpreted easily. It requires fewer times to obtain the variation in the series. Disadvantages of Range: As it considers only two extreme values, hence it doesnt include all the observations of the series. It fails to tell any thing about the characteristics of a distribution It is having very limited scope of applicability Having no mathematical treatment THE INTER-QUARTILE RANGE OR QUARTILE DEVIATION: A second measure of dispersion is the inter-quartile range which takes into account the middle half i.e., 50% of the data thus, avoiding the problem of extreme values in the data. Hence it measures approximately how far from the median one must go on either side before it can be include one-half the values of the data set. Inter-quartile range can be calculated by dividing the series of observations into four parts; each part of the series contains 25 percent of the observations. The quartiles are then the highest values in each of these four parts, and the inter-quartile range is the difference between the values of the first and the third quartile. Following are the steps of calculating the inter-quartile range: Arrange the data of the series in ascending order. Calculate the first quartile which is denoted as (Q1) by using the formula In case of grouped data the first quartile (Q1) can be calculated by using the formula Where N= number of observations in the series i.e., the sum of frequencies, L = lower limit of the quartile class, p.c.f. = commutative frequency prior to the quartile class, f = frequency of the quartile class and i = class interval. Quartile class can be determined by using the formula. Calculate the third quartile which is denoted as (Q3) by using the formula in case of ungrouped data. In case of grouped data the third quartile (Q3) can be calculated by using the formula Where N= number of observations in the series i.e., the sum of frequencies, L = lower limit of the quartile class, p.c.f. = commutative frequency prior to the quartile class, f = frequency of the quartile class and i = class interval. Quartile class can be determined by using the formula. THE MEAN/AVERAGE DEVIATION: Mean/average deviation is the arithmetic mean of the difference of a series computed from any measure of central tendency i.e., either deviation from mean or median or mode. The absolute values of each observation are calculated. Clark and Schekade opine mean deviation or average deviations as the average amount of scatter of the items in a distribution from either the mean or the median, ignoring the signs of the deviations. Thus the average that is taken of scatter is an arithmetic mean, which accounts for the fact that this measure is often called as mean deviation or average deviations. Calculations of Mean Deviation in case of Discrete Series: In case of discrete series, mean deviation can be calculated through following steps The first step is to calculate the mean or median or mode of the given series Compute the deviations of the observations of the series from the calculated mean or median or mode. This deviation is also denoted as capital letter D and is always taken as mod value i.e., ignoring the plus or minus sign. Take the summation of the deviations (sum of D) and divide it by number of observations (N). In the same way one can calculate mean deviation from median or mode in case of individual series. Calculations of Mean Deviation in case of discrete series: Mean deviation can be calculated in case of discrete series in a little bit different way. Following are some steps to calculate the average mean when the series is discrete. The first step is to calculate the mean or median or mode of the given series by using the formula as discussed in the previous chapter. Compute the deviations of the observations of the series from the calculated mean or median or mode value. This deviation is also denoted as capital letter D and is always taken as mod value i.e., ignoring the plus or minus sign. Multiply the corresponding frequency with each deviation value i.e., calculate f * D. Similarly, one can calculate the mean deviation or average deviation by taking deviations from median or mode. Calculations of Mean Deviation in case of continuous series: The first step is to calculate the mean or median or mode of the given series by using the formula as discussed in the previous chapter. In the second step, get the mid values of the observations (m) Compute the deviations of the observations of the series from the calculated mean or median or mode value. This deviation is also denoted as capital letter D = m mean or median or mode and is always taken as mod value i.e., ignoring the plus or minus sign. Multiply the corresponding frequency with each deviation value i.e., calculate f * D. Take the summation i.e., (sum of D) and divide it by number of observations (N). The formula may be Advantages of mean deviation: The computation process of mean deviation is based on all the observations of the series. The value of mean deviation is less affected by the extreme items. These are three alternatives available with the researcher while calculating the mean. One can consider the mean or median or mode. Hence it is more flexible in calculation. Disadvantages of mean deviation: The practical usefulness of mean deviation is very less. Mean deviation is not having enough scope for further mathematical calculations. Mod values are considered while calculating the mean deviation. It is criticized by some experts as illogical and unsound. THE STANDARD DEVIATION: Standard deviation or other wise called as root mean square deviation is the most important and widely used measure of variation. It measures the absolute variation of a distribution. It is the right measure that highlights the spread of the observation over and around the mean value. The greater the rate of variation of observations in a series, the greater will be the value of standard deviation. A small value of standard deviation implies a high degree of homogeneity among the observations in the series. If there will be a comparison between two or more standard deviations of two or more series, than it is always advisable to choose that series as ideal one which is having small value of standard deviation. Standard deviation is always measures from the mean or average value of the series. The credit for introducing this concept in the literature goes to Karl Pearson, a famous statistician. It is denoted by the Greek letter (pronounced as sigma) Standard deviation is calculated in following three different series: Standard deviation in case of Individual series Standard deviation in case of Discrete series Standard deviation in case of Continuous series All the above conditions are discussed in detail below. a. Standard deviation in case of individual series: In case of individual series, the value of standard deviation can be calculated by using two methods. Direct method- when deviations are taken from actual mean Short-cut method- when deviations are taken from assumed mean 1. Direct method- when deviations are taken from actual mean: Following are some steps to be followed for calculating the value of standard deviation. The first step is to calculate the actual mean value of the observation In the next column calculate the deviation from each observation i.e., find out () where is the mean of the series. In the next column calculate the square value of the deviations and at the end of the column calculate the sum of the square of the deviations i.e., Divide the total value with the number of observations (N) and than square root of the value. The formula will be . Since the series is having individual observations, some times it so happens that there is no need of taking the deviations. In such a case the researcher can directly calculate the value of the standard deviation. The formula for calculating directly is . 2. Short-cut method- when deviations are taken from assumed mean: In practical uses it so happens that while calculating standard deviation by using the arithmetic mean, the mean value may be in some fractions i.e., .25 etc. This creates the real problem in calculating the value of standard deviation. For this purpose, instead of calculating standard deviation by using the above discussed arithmetic mean methods, researchers generally prefer the method of short-cut which is nothing rather calculation of standard deviation by assuming a mean value. Following are some steps that to be followed for calculating standard deviation in case of assumed mean method: The first step is to assume a value from the X values as mean. This mean value is denoted as A. In the next step deviations are to be calculated from this assumed mean as (X-A) and this value is denoted as D. At the end of the same column, the sum of D () is to be calculated. Calculate the square of each observation of D i.e., calculate. The following formula is to be used to calculate standard deviation of the series. where N is the number of observations in the series. b. Standard deviation in case of discrete series: Discrete series are the series which are having some frequencies or repetitions of observations. In case of a discrete series standard deviation is calculated by using following three methods: when deviations are taken from actual mean when deviations are taken from assumed mean Following are the detailed analysis of the above the two methods. 1. When deviations are taken from actual mean: The steps to calculate standard deviation when deviations are calculated from the actual mean are The first step is to calculate the actual mean value of the observation In the next column calculate the deviation from each observation i.e., find out () where is the mean of the series, this can be denoted as D. In the next column calculate the square value of the deviations and at the end of the column calculate the sum of the square of the deviations i.e., Multiply corresponding frequencies of each observation with the value of D2 in the next column. Divide the total value with the number of observations (N) and than square root of the value. The formula will be 2. When deviations are taken from assumed mean: The steps to calculate standard deviation when deviations are calculated from the actual mean are The first step is to assume a mean value from the observations In the next column calculate the deviation from each observation i.e., find out () where A is the mean of the series, this deviation can be denoted as D. In the next column calculate the square value of the deviations and at the end of the column calculate the sum of the square of the deviations i.e., Multiply corresponding frequencies (f) of each observation with the value of D2 in the next column. Use the following formula to calculate standard deviation c. Standard deviation in case of Continuous series: Standard deviation in case of a continuous series can be calculated by using the following steps Calculate the mid value of the series and denote it as ‘m. Assume any value from the mid values and denote it as A Deviations can be calculated from each series i.e., calculate m – A and than divide it with the class interval value (i) i.e., Multiply the corresponding frequencies of each observation with the deviation value and take the sum at the end of the column i.e., calculate In the next column square the deviation values of each observation i.e., calculate Multiply the value of with its frequencies i.e., calculate Use the following formula to get standard deviation. Properties of standard deviation: As tool of variance, standard deviation is used as a good measure of interpretation of the scatteredness of observation of a series. It is a fact that in a normal distribution approximately 68 per cent of the observations of a series lies less than standard deviation away from the mean, again approximately 95.5 per cent of the items lie less than 2 standard deviation value away from the mean and in the same way 99.7 per cent of the items lie within 3 standard deviations away from the mean. Hence covers 68.27 per cent of the items in a series with normal distribution. covers 95.45 per cent of the items in a series with normal distribution and covers 99.73 per cent of the items in a series with normal distribution. Advantage of Standard Deviation: Following are some advantages of standard deviation as a measure of dispersion This is the highest used technique of dispersion. It is regarded as a very satisfactory measure of the dispersion of a series. It is capable of further mathematical calculations. Algebraic signs are not ignored while measuring the value of standard deviation of a series. It is less affected by the extreme observations of a series. The coefficients make the standard deviation very popular measure of the scatteredness of a series. Disadvantages of standard deviation: The disadvantages are It is not easy to understand the concept easily and quickly. It requires a good exercise to calculate the values of standard deviation. It gives more weight to observations which are away from the arithmetic mean. THE COEFFICIENT OF VARIATION: Another useful statistical tool for measuring dispersion of a series is coefficient of variation. The coefficient of variation is the relative measure of standard deviation which is an absolute measure of dispersion. This tool of dispersion is mostly used in case of comparing the variability two or more series of observation. While comparing, that series for which the value of the coefficient of variation is greater is said to be more variable (i.e., the observations of the series are less consistent, less uniform, less stable or less homogeneous). Hence it is always advisable to choose that series which is having less value of coefficient of variation. The value of coefficient is less implies more consistent, more uniform, more stable and of course more homogeneous. The value of coefficient of variation is always measured by using the value of standard deviation and its relative arithmetic mean. It is denoted as C.V., and is measured by using simple formula as discussed below: In practical field, researchers generally prefer to use standard deviation as a tool to measure the dispersion than that of coefficient of variance because of a numbers of reasons (researchers are advised to refer any standard statistics book to know more on coefficient of variance and its usefulness). GINI COEFFICIENT AND THE LORENZ CURVE: An illuminating manner of viewing the Gini coefficient is in terms of the Lorenz curve due to Lorenz (1905). It is generally defined on the basis of the Lorenz curve. It is popularly known as the Lorenz ratio. The most common definition of the Gini coefficient is in terms of the Lorenz diagram is the ratio of the area between the Lorenz curve and the line of equality, to the area of the triangle OBD below this line (figure-1). The Gini coefficient varies between the limits of 0 (perfect equality) and 1 (perfect inequality), and the greater the departure of the Lorenz curve from the diagonal, the larger is the value of the Gini coefficient. Various geometrical definitions of Gini coefficient discussed in the literature and useful for different purposes are examined here. CONCLUSIONS: The study of dispersion will enables us to know whether a series is homogeneous (where all the observations remains around the central value) or the observations is heterogeneous (there will be variations in the observations around the central value Hence it can be said that a measure of dispersion describes the spread or scattering of the individual values of a series around its central value. For this there are a numbers of methods to determine the variations as discussed in this chapter. But it is always confusing among the researchers that which method is the best among the different techniques that we have discussed? The answer to this question is very simple and says that no single average can be considered as best for all types of data series. The most important factors are the type of data available and the purpose of investigation. Critiques suggest that if a series is having more extreme values than standard deviation as technique is to be avoided. On the other hand in case of more skewed observations standard deviation may be used but mean deviation needs to be avoided where as if the series is having more gaps between two observations than quartile deviation is not an appropriate measure to be used. Similarly, standard deviation is the best technique for any purpose of data. SUMMARY: The study of dispersion will enables us to know whether a series is homogeneous (where all the observations remains around the central value) or the observations is heterogeneous (there will be variations in the observations around the central value). Dispersion when measured on basis of the difference between two extreme values selected from a series of data. The two well known measures are (i) The Range and (ii) The Inter-quartile Range. Dispersion when measured on basis of average deviation from some measure of central tendency. The well known measures are (i) The Mean/average deviation, (ii) The Standard Deviation, (iii) The Coefficient of variation and (iv) The Gini coefficient and the Lorenz curve The range is defined as the difference between the highest value and the lowest value of the series. Range as a measure of variation is having limited applicability. The inter-quartile range measures approximately how far from the median one must go on either side before it can be include one-half the values of the data set. Mean/average deviation is the arithmetic mean of the difference of a series computed from any measure of central tendency i.e., either deviation from mean or median or mode. The absolute values of each observation are calculated. A small value of standard deviation implies a high degree of homogeneity among the observations in the series. If there will be a comparison between two or more standard deviations of two or more series, than it is always advisable to choose that series as ideal one which is having small value of standard deviation. Standard deviation is always measures from the mean or average value of the series. The coefficient of variation is the relative measure of standard deviation which is an absolute measure of dispersion. This tool of dispersion is mostly used in case of comparing the variability two or more series of observation. The most common definition of the Gini coefficient is in terms of the Lorenz diagram is the ratio of the area between the Lorenz curve and the line of equality, to the area of the triangle below the equality line.
