The human nature Essay Example for Free
The human nature EssayHow much is human frustration worth? Is it worth losing a chance to buy a present for the girl you like? Or is it worth participating in a drawing which is nothing more but a silly tragic fatal ritual? I was asking these questions while reading James Joyces Araby and Shirley capital of Mississippis The Lottery.For me, both stories hold the ultimate point of human despair at this point, the person is no longer able to control his (her) manners and surrenders under the pressure of overwhelming circumstances. I think that frustration is the central element of both stories it touches the depth of the readers soul and turns into disruptive revelation about the perversity and hideousness of the human nature.Human strength and selection has no limits human evil and self-interest are unlimited, too. James Joyces Araby shows human frustration in its powerlessness in the face of insuperable circumstances. Every good dawn I lay on the floor in the front parlour w atching her door. When she came out on the doorstep my heart leaped (Joyce 62). The whole life of the anon. narrator is filled with joy of seeing the green lady walking in front of him, and passing her before their ways diverge.He lives his life from morning to morning, when he will see Magans sister again. This is the life full of waiting this is the life full of expectation, anxiety, dreaming and almost physical attraction. The same is the life of villagers whom Jackson describes in her The Lottery. It is the life full of expectation mixed with the feeling of threat, fear, and imminence of the coming end Bobby Martin already stuffed his pockets full of stones, and the other boys soon followed his example, selecting the smoothest and roundest stones (Jackson 10). As the young boy cannot wait to visit the bazaar I could not call my wandering thoughts to liveher.I had hardly any patience with the serious work of life which, now that it stood between me and my desire, seemed to me c hilds play (Joyce 63), the villagers cannot wait to hear when the new victim of the annual ritual will be declared guess we better draw started, get this over with, sos we can go back to work (Jackson 13).The deeper Joyce goes into the young boys soul, the larger is the prairie between his promise to visit the Araby bazaar and the realization of his inability to meet the promise Nearly all stalls were closed and the greater part of the hall was in darkness (Joyce 65). How bright and terriblely sincere Joyces revelation could be, Jacksons news report has gone far beyond Joyces reasonable limits. Jackson has gone even deeper to the moment of unexpectedness which tryd the unlimited nature of human mercenary character.In the light of Jacksons The Lottery, Araby produces an impression of the boys relatively mild reconciliation with the surrounding opportunities and circumstances. Moreover, I feel that Joyce still leaves some hope that everything will transform ultimately, there wil l be another bazaar and another girl, although the young boy does not yet understand it.On the contrary, Jackson uses unexpectedness to emphasize how far human coldness, rationality, and perversity can go the author shows, how easily humans turn into beasts when they pursue material interests, leaving no hope to carry the draftsmanships trap. Jackson shows how human desire to kill turns into a usual feeling, when it becomes regular for and acceptable by other community members the whole lottery took less than two hours, so it could begin at ten oclock in the morning and still be through in time to allow the villagers to get home for noon dinner (Jackson 10).ConclusionBoth stories end up in frustration for Joyces character, frustration is reflected in the hollow sound of two pennies that declination against the sixpence in my pocket (Joyce 66). A creature driven and derided by vanity (Joyce 66) is the end result of Joyces striving towards recognition and love. For Tessie Hutchinso n, frustration becomes real as she holds the slip of paper that has a black spot on it, the black spot Mr. Summers had made the night before with the heavy pencil in the ember company office (Jackson 17).Later, this frustration turns into the feeling of inevitability of tragedy, when a stone hit her on the side of the head (Jackson 17). In both stories, frustration is the shocking reflection of the human hideousness, cruelty, and indifference which leave no chance for spiritual and physical resurrection.Works CitedJackson, S.

His tomb, with its army of life-size terracotta soldiers, has been partially excavated. I. Romes Creation of a Mediterranean Empire, 753 B. C. E. -330 C. E. A. Geography and resources 1. Italy and Sicily are at a crossroads of the Mediterranean and serve as a link between Africa and Europe. Rome is at a crossroads of the Italian peninsula. 2.Italys natural resources allowd navigable rivers, forests, iron, a mild climate, and enough cultivatable land to support a large population of farmers whose surplus product and labor could be exploited by the Roman state. B. A repu blic of farmers 1. Rome was inhabited at least as early as 1000 B . C. E. According to legend it was ruled by seven kings between 753 B. C. E. and 507 B. C. E. Kingship was eliminated in 507 B. C. E. when representatives of the senatorial class of large landholders overthrew the last king and realized a republic. 2. The centers of political power were the two consuls and the Senate.In practice, the Senate made laws and governed. 3. The Roman family consisted of several generations accompaniment under the unattackable authority of the oldest living male, the patriarch. 4. Society was hierarchical. Families and individuals were tied together by patron/client relationships that institutionalized inequality and gave both sides of the relationship conclude to cooperate and to support the status quo. 5. Roman women had relatively more freedom than Greek women, but their legal status was st tuberculous that of a child, subordinate to the paterfamilias or her own or her husbands family .Eventually procedures evolved which made it possible for some women to become independent after the death of their fathers. 6. Romans worshiped a large number of necromantic spirits as well as major gods such as Jupiter and Mars. Proper performance of ritual ensured that the gods continued to favor the Roman state. C. Expansion in Italy and the Mediterranean 1. Rome began to expand, at first slowly and then very rapidly in the third and second centuries B. C. E. until it became a huge Mediterranean empire. contingent explanations for this expansion include greed, aggressiveness, the need for consuls to point themselves as military commanders during their one year in office, and a constant fear of being attacked. 2. During the first set of expansion, Rome conquered the rest of Italy (by 290 B. C. E. ). Rome won the support of the people of Italy by granting them Roman citizenship. As citizens, these people then had to provide soldiers for the military. 3. In the next stages of ex pansion, Rome first defeated Carthage to gain image over the western Mediterranean and Sicily, Sardinia, and Spain (264-202 B. C. E. ).Next, between 200 and 30 B. C. E. Rome defeated the Hellenistic kingdoms to take over the lands of the Eastern Mediterranean. Between 59 and 51 B. C. E. , Gains Julius Caesar conquered the Celts of Gaul. 4. The Romans used local elite groups to administer and valuate the various provinces of their rapidly expanding and far-flung empire. A Roman governor, who served a single one- year term in office, supervised the local administrators. This system was inadequate and prone to corruption. D. The failure of the republic 1. As Rome expanded, the social and economic bases of the Roman republic in Italy were undermined by change.While men from independent farming families were forced to devote their time to military service, large landowners bought up their land to create great estates called latifundia. This meant both a decline in Romes source of soldi ers and a decline in food production, as latifundia owners preferred to grow funds crops like grapes rather than staple crops such as wheat. 2. Since slave labor was cheap in an expanding empire, Italian peasants, driven off the land and not assiduous by the latifundia, drifted into the cities where they formed a fractious unemployed underclass. 3.As the independent farming family that had been the traditional source of soldiers disappeared, Roman commanders built their armies from men from the underclass who tended to transgress their loyalty, not to the Roman state, but to their commander. This led to generals taking control of politics, to civil wars, and finally to the end of the republican system of government. 4. Julius Caesars grandnephew Octavian (also known as Augustus) took power in 31 B. C. E. , reorganized the Roman government, and ruled as a military dictator. After Augustus died, several members of his family succeeded him.However, the position of emperor was not ne cessarily hereditary in the end, armies chose emperors. E. An urban empire 1. About 80 percent of the 50 to 60 million people of the Roman Empire were rural farmers, but the empire was administered through and for a network of cities and towns. In this sense, it was an urban empire. Rome had about a million residents, other large cities (Alexandria, Antioch, Carthage) several hundred thousand each, darn many Roman towns had populations of several thousand. 2. In Rome, the upper classes lived in elegant, well-built, well-appointed houses many aristocrats also owned country villas.The poor lived in dark, dank, fire-prone wooden tenements in squalid slums built in the low-lying parts of the city. 3. Provincial towns imitated Rome both in urban planning and in urban administration. The local elite, who served the interests of Rome, prevail town councils. The local elite also served their communities by using their wealth to construct amenities such as aqueducts) baths, theatres, garde ns, temples, and other public works and merriment projects. 4. Rural life in the Roman empire involved lots of hard work and very little entertainment.Rural people had little refer with representatives of the government. By the early centuries C. E. absentee landlords who lived in the cities owned more or less rural land, while the land was worked by tenant fanners supervised by hired foremen. 5. Manufacture and trade flourished under the pax romana. Grain had to be imported to feed the huge city of Rome. Rome and the Italian towns (and later, provincial centers) exported glass, metalwork, pottery, and other manufactures to the provinces. Romans also imported Chinese silk and Indian and Arabian spices. 6. One of the effects of the Roman Empire was Romanization.In the western part of the Empire, the Latin language, Roman clothing, and the Roman lifestyle were adopted by local people. As time passed, Roman emperors gradually extended Roman citizenship to all free male adult inhabi tants of the empire. F. The rise of Christianity 1. Jesus lived in a society marked by resentment against Roman rule, which had inspired the belief that a Messiah would arise to liberate the Jews. When Jesus sought to reform Jewish religious practices, the Jewish authorities in Jerusalem turned him over to the Roman governor for execution. 2.After the execution, Jesus disciples continued to spread his teachings they also spread their belief that Jesus had been resurrected. At this point, the target of their proselytizing was their fellow Jews. 3. The target of proselytizing changed from Jews to non-Jews in the 40s-70s C. E. First Paul of Tarsus, an Anatolian Jew, discovered that non-Jews (gentiles) were much more receptive to the teachings of Jesus than Jews were. Second, a Jewish revolt in Judaea (66 C. E. ) and the subsequent Roman reconquest destroyed the original Jewish Christian community in Jerusalem. 4.Christianity grew slowly for two centuries, developing a hierarchy of prie sts and bishops, hammering out a commonly accepted theological doctrine, and resisting the persecution of Roman officials. By the late third century, Christians were a sizeable minority in the Roman Empire. 5. The expansion of Christianity in the Roman empire came at a time when Romans were increasingly dissatisfied with their traditional religion. This dissatisfaction inspired Romans to become interested in a variety of mystery cults and universal creeds that had their origins in the eastern Mediterranean.G. Technology and transformation 1. The Romans were expert military and civil engineers. Among their accomplishments were bridge-building, ballistic weapons, elevated and underground aqueducts, the use of arches and domes, and the invention of concrete. 2. Following Augustus death, the army was organized primarily for defense. The Rhine-Danube frontier was protected by a string efforts long walls protected the frontiers of North Africa and Britain. On the eastern frontier, the Rom ans fought for centuries against the Parthians. Neither side made any substantial gains. 3.The state system constructed by Augustus worked well until what historians call Romes third-century crisis. The symptoms of this crisis were frequent change of rulers raids by German tribesmen from crossways the Rhine-Danube frontier and the rise of regional power when Rome seemed unable to guarantee security. 4. Romes economy was undermined by the high cost of defense, debasement of the currency and consequent inflation, a disruption of trade, reversion to a barter economy, disappearance of the municipal aristocracy of the provincial cities, and a movement of population out of the cities and back into the rural areas.5. The emperor Diocletian (r, 284-305) saved the Roman state by instituting a series of reforms that included price controls and regulations that required certain people to stay in their professions and to train a son to succeed them. Some side effects of these reforms include a flourishing black market and a growing feeling of resentment against the government. 6. Constantine (r. 306-37) reborn to Christianity in 337 and patronized the Christian church, thus contributing to the rise of Christianity as the official religion of the empire.Constantine also transferred the capital of the empire from Rome to the eastern city of Byzantium, which he renamed Constantinople. II. The Origins of Imperial China, 221 B. C. E. -220 C. E. (We covered very little of this information) A. Resources and population 1. China is a large region marked by significant ecological, topographical, biological, and climatic diversity. 2. The two most important resources that supported the imperial Chinese state were agricultural production and labor. Agricultural production in China was intensive and was taxed by the government.The most productive agricultural region was the Yangzi Valley, which began to be linked to the centers of political power (Changan and Luoyang) by canals. 3. Both the Qin and the Han governments exploited the labor power of rural China by demanding that peasant families supply men for labor and for service in the military. A periodic census and regularly updated records of land and households enabled officials to collect the proper amount of taxes, labor service, and military service. 4. Throughout antiquity, the Han Chinese people expanded at the expense of other ethnic groups.Han expanded into areas that were adapted for settled agriculture. They did not expand into areas that were suitable only for nomadic economies. B. Hierarchy, obedience, and belief 1. The family was the basic unity of society. The family was conceived of as an unbroken chain of generations including the ancestors as well as the current generations. Ancestors were thought to take an active interest in the affairs of the current generation, and they were routinely consulted, appeased, and venerated. 2.The teachings of Confucius were a fundamental source of values for family, social, and political organization. Confucius regarded hierarchy as natural and placed absolute authority in the hands of the father. Family members were thought of as part of the group, not as individuals. Confucius also believed that people would properly fulfill their graphic symbols if they were correctly instructed and imitated good role models. 3. According to the ideals of the upper classes, women were to cook, take care of household chores, respect their parents-in-law, and obey their husbands.Lower-class women may have been less constrained. Marriages were arranged, and a new wife had to prove herself to her husband and to her mother-in-law through hard work, obedience, devotion, and by bearing sons. 4. Chinese believed in a number of nature spirits to whom they sacrificed. Unusual natural phenomena were regarded as ill omens. The landscape was thought to channel the flow of evil and good power, and experts in fengshui (geomancy) were employed to identify the m ost fortunate location and orientation for buildings and graves. C. The first Chinese empire 1.After the Warring States Period (480-221 B. C. E. ), the state of Qin united China. Factors that enabled Qin to accomplish reunification may include the ability and ruthlessness of the Qin ruler, Shi Huangdi and his prime minister, Li Si Qins location in the Wei valley with its predominantly rural population of independent farming households and Qins experience in mobilizing manpower for irrigation and flood-control projects, which had strengthened the central government. 2. Upon uniting China, the Qin established a strong centralized state on the Legalist model.Shi Huangdi and Li Si suppressed Confucianism, eliminated rival centers of authority, abolished primogeniture and slavery, and constructed a rural economy of free land-owning/tax-paying farmers. They standardized weights and measures, break down the empire together with roads and defended it with a long wall. 3. The oppressive nat ure of the Qin regime and its exorbitant demands for taxes and labor led to a number of popular rebellions that overthrew the dynasty after the death of Shi Huangdi in210 B. C. E. D. The long reign of the Han (206 B. c. s. -220 C. E. ) 1.Liu Bang, a peasant who defeated all other contestants for control of China, established the Han dynasty. The Han established a political system that force on both Confucian philosophy and Legalist techniques. 2. After a period of consolidation, the Han went through a period of territorial expansion under Emperor Wu (r. 140-87 B. C. E. ). During the occidental Han period (202 B. c. E. -8 C. E. ) the capital was at Changan. During the Eastern Han (23-22 C. E. ) the capital was at Luoyang. 3. Changan was an easily defended walled city with easy access to good arable land.The population in 2 C. E. was 246,000. Other cities and towns imitated the urban planning of Changan. 4. The elite ofChangan lived in lived in elegant multistoried houses arranged o n broad, well-planned boulevards. They dressed in fine silks, were connoisseurs of art and literature, and indulged in numerous entertainments. The common people lived in closely packed houses in largely unplanned, winding alleys. 5. The emperor was supreme in the state and in society. He was regarded as the Son of Heaven, the link between heaven and the human world. Emperors were the source of law.But anything that went seriously wrong could be interpreted to mean that the emperor was felonious of misrule and that he was losing the Mandate of Heaven. Emperors lived in seclusion, surrounded by a royal retinue that included wives, family, servants, courtiers, and officials. 6. The central government was run by two chief officials and included a number of functionally specialized ministers. Local officials collected taxes, drafted men for corvee labor and military service, and settled local disputes. Most people had no contact with the central government. 7.Local officials were suppl ied by a class of moderately wealthy, educated local landowners that historians refer to as the gentry. The gentry adopted Confucianism as their ideology and pursued careers in the civil service. E. Technology and trade 1. In the field of metallurgy, China advanced from bronze to iron by about cholecalciferol B. C. E. Rather than make wrought-iron goods (as the Romans did), Chinese ironworkers melted the iron and used molds to make harder and more durable cast-iron and steel tools and weapons. 2. Other technological innovations of the Han period include the crossbow, cavalry, the watermill, and the horse collar.New transportation and communications technology included a road system, courier systems for carrying government communications, and canals. 3. The Han period also saw significant outgrowth in the size and number of urban areas. Somewhere from 10 to 30 percent of the population of Han China lived in towns. 4. Long-distance commerce was a significant part of the Han economy . The most important export was silk, and the most important export route was the Silk Road through Central Asia. The Chinese government sought to control this route by sending armies and colonists to Central Asia. F. Decline of the Han Empire1. The Han Empires major security problem was the nomadic tribes on its northern border. Nomadic groups were usually little(a), but during the Han, the Chinese faced a confederacy of nomads called the Xiongnu. China attempted to deal with the Xiongnu threat by strengthening its defenses (particularly its cavalry) and by making more compliant nomads into tributaries. 2. The Han Empire was undermined by a number of factors. First, the expense of defending the northern borders was a tremendous financial burden. Second, nobles and merchants built up large landholdings at the expense of the small farmers.These large landholders were able to resist taxation and became independent of government control. Third, the system of military conscription bro ke down and the central government had to rely on mercenaries whose loyalty was questionable. 3. These factors compounded by factionalism at court, official corruption, peasant uprisings, and nomadic attacks led to the fall of the dynasty in 220 C. E. China entered a period of political fragmentation that lasted until the late sixth century. III. Imperial Parallels A. Similarities Between the Roman and Han Empires 1.The Han and Roman Empires were similar in respect to their family structure and values, their patterns of land tenure, taxation, and administration, and in their empire building and its consequences for the indistinguishability of the conquered areas. 2. Both empires faced common problems in terms of defense, and found their domestic economies undermined by their military expenditures. 3. Both empires were overrun by new peoples who were then deeply influenced by the imperial cultures of Rome and of China. B. Differences Between the Roman and Han Empires 1. In China, th e imperial model was revived and the territory of the Han empire re-unified.The former Roman empire was never again reconstituted. 2. Historians have tried to explain this difference by pointing to differences between China and the Roman world in respect to the concept of the individual, the greater story of social mobility in Rome than in Han China, and the different political ideologies and religions of the two empires. Conclusion A. The Qin and the Han were able to unify China and build an empire rapidly because the theme had already been set in the Zhou and Warring States Periods Rome constructed its empire slowly and without precedents to draw upon.B. The Han and the Roman empires maintained and administered large territories and populations by virtue of their ability to organize large professional armies and professional bureaucracies. C. Both empires provided long periods of peace and prosperity, but they were undermined by the high cost of defense and by the heavy tax burd en, which this put on their people. D. The Han dynasty constructed a political system that would be revived and modified by subsequent dynasties the Roman empire was never restored.

However, the real focus pillows on the content. In Kelly Scott capital of Wisconsins State of media report, it reit dateted that content is and always will remain, king (Madison 2013).With quality programming content like Who is HBOs Girls for? (Smith 2012) that shows about different women and their lives, the show has tell apart itself from other media programming content. The show not only caters to roughlyly female reference demographics where most females are at home watching TV the audience are able to relate their lives to the series show and this creates the stickiness to the boob tube drama series because of its content. This is similar to other shows like Sex and the City .Subscription TV sagacity of TV households in Australia is increasing over the years. It is forecasted to increase from 30% in 2008 to 35% in 2017 (Maurer, Emmanuel Parker 2013). by dint of subscription TV, it provides different content and choices to the lulus like sport, movies, cartoons, anatomy shows. It also allows, through digital set-top boxes, the viewers abide record and view the program as and when he prefers. This is not available in the traditional go around TV when the viewers have to watch a show through a fixed schedule.The regulatory environment for free-to-air television in Australia continues to change. In 2012, the convergency Review highlighted the need for diversity in media and more Australian content (ABC News 2012). With digital and primary channels, it allows broadcasters the flexibility to provide more Australian content. (Cosgrove, Schaffer Horlin 2013)Through digital technologies, viewers can watch live broadcast shows like Formula-1 racing, AFL, English Premier League or Australian Open Tennis. In most networks, it also allows viewers to have video-on-demand in which the viewer can select the movies at their own convenience. Viewers can also use time-shifting features in their set-top to leap out the advertisements if they would like to.Thus, with superior content and rapid advancement in technology, TV providers and networks can create more value to the TV consumers (Maurer, Emmanuel Parker 2013). Consumers will now top more hours watching TV and be willing to spend more money in subscription or video-on-demand fees.Enhancing user experiencesTV has advanced tremendously in recent years because of digital technologies advancement. From traditional black and white or colour TV, it now has features like high definition multimedia interface (HDMI), Dolby butt on effects to 3D technology offering real-life effects to viewers. In addition, in the digital era, TV has provided more connectivity with other whatchamacallits su ch as Nintendo wii or Xbox 360 game machine, Internet access for online games, music and many more. Many of these devices provide multi-user games that allow family members to enjoy playing the games in the living room together. Imagine the effects on family bonding when parents and their children can enjoy a game of tennis for several hours in front of the television in the living room.Through technologies, TV has created a cocooning impulse (Tryon 2012, p. 291) that unite families and brings them together (Cosgrove, Schaffer Horlin 2013), creating bonding and harmony in the family. exploiter experiences are also enhanced through the superior content delivery through digital technologies. Movies are more readily available in household TV through Pay TV or Subscription TV options. TV drama series like Serangoon made by Australian TV or Lena Dunhams Girls are some examples where these sitcoms series which are made for television (Mundell 2013) have created a glueing effects on user experiences to the TV.Technologies like video-on-demand and built-in program recorders of TV show allows time-shifting, thus watching TV becomes a recreation and a treat for housewives (Venkatraman 2013).

Technological innovations in 3D technology for TV offer a more interactive television user experience throu gh captivating user interfaces like 3D animations or real-time interaction with online apps like Facebook and chirp (Connected Media World 2013).Platform mobilityTraditional scheduled television broadcasts and viewing through receive-only television sets have been increasingly supplanted by digital technologies offering viewer employ and convenience through video-on-demand, viewing of television programs across a multitude of devices such as smart mobile phones, Apple iPad tablets, Smart Internet-Ready Television, and sophisticated digital set-top boxes provided by cable and internet television operators.As pointed out by Sterne, people can spend many hours of their time watching specific programs using their mobile devices and still not realizing and thinking of themselves as watching television (Sterne 2012). Tyron defines platform mobility as the idea that films and television shows can move seamlessly from one device to another with minimal interruption (Tyron 2012). He also n oted that digital delivery technologies allowed workers and families with hectic schedules, the ability to watch television programs wherever and whenever they would like (Tyron 2012). This provides them the single(a) and personalized experiences that cater to their own tastes and needs, enhancing the overall compelling user viewing experiences.Tyron (2012) further argues that the viewer empowerment through digital technologies has an overarching impact on viewer engagement as more mobile devices like iPad tablets, laptops and smartphones can provide the platform mobility to the users. Members of the family can watch different or same television program in different places within the house. This also empowered individual viewer to access to a wide range of choice selection like viewing on-demand movies on personal mobile device, online chat using social media applications such as Twitter and Facebook or speaking with their friends on their mobile phones while watching a sport game. Platform mobility also allows producers like Warner to sell their films through this mode of digital delivery to viewers who can purchase them via iPhone apps. Viewers can choose to view their favorite movies as and when they would like, in the living room or on a bus.Thus it can be said that the resurgence of TV as a home for quality entertainment can be partly attributed to demand spawned by viewers mobile and digital era lifestyles, and their desire to be an engaged viewer instead of being a passive one.ConclusionIn conclusion, it is apparent that digital technologies will continue to remain a dominant force in the television industry as a home for quality entertainment. TV network services providers continue to gain on the advancement of the digital technologies so as to explore and offer more innovative and value-add services to TV subscribers.Advancement in the Internet or other media delivery channels like satellite, broadcast via cable, allows service providers to increase their revenue streams by offering more superior content and options and enhancing user experiences by making use of newer technology like 3D. Platform mobility remains the focus of the future research in the digital technologies in the TV industry. This is because of the ever ever-changing lifestyles and demanding needs of the younger generation for more contents and mobility.Hence, we will not see the demise of the television but rather a revolution that television plays an important part in the home for quality entertainment, through the digital technologies and it continues to provide intrinsic value in family bonding.ReferencesABC News 2012, Government releases crossing review, viewed 7 June 2014, http//www.abc.net.au/news/2012-04-30/govt-releases-convergence-review/3980316.Cosgrove, C, Schaffer, B Horlin, S 2013, Free-to-air television, PWC Outlook Australian Entertainment Media, viewed 7 June 2014, https//outlook2013.ezimerchant.com/category31_1.htm.Connected Media World 20 13, The evolution of the TV User Experience, viewed 7 June 2014, http//www.connectedmediaworld.com/NewsArticle.aspx?ArticleID=c73b0e36-43ca-4a84-93be-835f4bfe222e.Madison, K.S 2012, 2012 State of media, Chicago KSCMediaMadison, K.S 2013, 2013 State of media, Chicago KSCMediaMaurer, D, Emmanuel, R Parker, A 2013, Subscription television, PWC Outlook Australian Entertainment Media, viewed 7 June 2014, https//outlook2013.ezimerchant.com/category38_1.htm.Mundell, I 2013, Smallscreen recognize makes a big splash, Variety, viewed 2 June 2014, http//variety.com/2013/film/news/smallscreen-fare-makes-a-big-splash-1118064535/.Nielsen 2011, The cross-platform report, State of The Media, pp. 2-10.Smith, S.E. 2012, Who is HBOs Girls for?, Global Comment, viewed 7 June 2014, http//globalcomment.com/who-is-hbos-girls-for/.Sterne, J 2012, Formatted to fit your screen, FlowTV, vol. 15, no. 5, http//flowtv.org/2012/01/formatted-to-fit-your-screen/.Tyron, C 2012, Make any room your TV room digital delivery and media mobility, Autumn, 53(3), pp. 286-300.Uniyal, D 2012, 3D Technology Shaping the future of entertainment, diary of Mass Communication, 10(1), pp. 50-55.Venkatraman, M 2013, Consuming digital technologies and making home, Journal of Business Research, Issue 66, p. 21

Crank And Slotted Lever Mechanism Engineering Essay
Crank And Slotted Lever appliance Engineering EssayIn a kinematic bowed stringed instrument when one link is fixed, then that chain is cognise as mechanism. It may be used for bestowting or transforming motion for example engine indicators, typewriters etc.1A mechanism which has four tie in is known as simple mechanism, and a mechanism which has more than four links is known as complex mechanism. A mechanism which is required to transmit some particular type of work is knows as machines. In certain cased the elements have to be designed to withstand the depicts safely.A mechanism is a kinematic chain in which kinematic pairs are connected in such a way that first link is joined to the last link to transmit a predetermined constrained motionThe divers(a) parts of the mechanism are c whollyed as links or elements. When twain links are in strain and a congress motion is possible, then they are known as a pair. An arbitrary set of a link which forms a closed chain which is cap able of relative motion and that potty be made into a rigid structure by adding a single link is known as kinematics chain. To form a mechanism from a kinematics chain one of the link must be fixed. The technique obtaining different mechanism by fixing the various link in turn is knows as upending. 2 build 1.1-Chart illustrating kinematic pair makes up a machineCHAPTER 2KINEMATIC PAIRSTwo links that can move with respectfulness to each other by a mechanical constraint between them, with one or more degrees of granting immunityThe relative motion between two links of a pair can take different form. Three types of pair are identified as overturn pairs and these are the commonly occurring ones.skid much(prenominal) as occurs between a piston and a cylinderTurning Such occurs with a wheel on an axle screw propeller Motion Such as occurs between a nut and a bolt both other cases are considered to be combination of sliding and rolling is called higher pairs. Screw pair is higher pai r as it combines turning and sliding.2.1 Classification of Kinematic equatesSince kinematics pairs deals with relative motion between two links then can be classifies base on the characteristics of relative motion between two bodies.The type of relative motion between the elementsThe type of contact between the elementsThe type of closure1The type of relative motion between the elementsThe kinematic pair according to type of relative motion can classified as belowSliding PairTurning PairRolling PairScrew PairSpherical Pair2.1.2 The type of contact between the elementsThe kinematic pair according to type of contact between the elements can be classifiedLower PairHigher Pair2.1.3 The type of closureThe kinematic pair according to type of closure between the elements can be classified asSelf -Closed PairForce -Closed Pair2.2 GRUBLERS CRITERION FOR PLANAR applianceThe Grublers criterion applies to mechanism with only single degree of freedom joints where the overall movability of the mechanism is unity.Subtituting n=1 and h=0 in kutzbach equation we have 3F= 3 (n-1) 2j hThe equation is known as Grublers criterion for plane mechanisms with constrained motion.2j-3n+h+4=0Where, F= procedure of degrees of freedom of a chainj= number of lower kinematic pairsh = number of higher kinematic pairsn= number of linksWhen F=1, the linkage is called a mechanism.When F=0 it forms a structure. That is an application of extraneous force does not make up relative motion between any links of a linkageWhen F1 the linkage will require more than one external driving force 2 obtain constrained motionWhen F2.3 KINEMATIC CHAINA Kinematic Chain is defined as a closed web of links, connected by kinematic pairs so that the motion is constrained.First a network of links to give constrained motion, certain conditions are to be satisfied. Minimum number of three links is required to form a closed chain .The three links are connected with turning pairs.Fig.2.1 (a) A Five-Link Kinematic C hain (b) Six-Link Kinematic Mechanism2.3.1 Types of kinematic chainsThe most important kinematic chains are those which consists of four lower pairs, each pair being a sliding pair or a turning pairFour Bar Chain or Quadric cyclic ChainSingle Slider Crank chainDouble yellow-bellied terrapin ballock chain2.3.2 InversionsInversion is a method of obtaining different mechanisms by fixing different links in a kinematic chain. A particular inversion of a mechanism may give rise to different mechanism of practical unity, when the proportions of the link are changed 2.CHAPTER 3SLOTTED LINK QUICK RETURN MECHANISMSlotted link mechanism which is commonly used in shaper mechanism.

This makes the slotted crank B.This makes the slotted crank to oscillate about(predicate)(predicate) one end C.The oscillation motion of slotted crank makes ram to reciprocate. The intermediate D is required to accommodate the rise and fall of the crank.Crank Pin A decides the length of the strokes of the shaper. The further its away from the center of the bull wheel longer is its stroke.The cutting stroke of the ram is complete while crank pin moves from A to A1 and slotted link goes from left to right.During return stroke pin moves from A1 to A and link moves from right to leftCutting succession/Idle Time = Angle of AZA1/ Angles of AZA23.1 maker M ECHANISMThe working of a shaper mechanism is that it has two stokes. One is forward stroke and the other is return stroke. Clearing up more about these two strokes is that in the forward stroke the material is feeded, where as in the return stroke is an idle stroke when no material is feeded.6Fig 3.2 manufacturer MechanismShaping process which involves only short setup time and uses only inexpensive faunas. Shaping is used for the production of gears ,splined shafts racks etc. it can produce one or two such parts in a shaper less time that is required to setup for production. Other alternatively equipment with a higher output rate is required. 5The cost per cubic cm of metal removal by shaping may be as five multiplication more than that of the removal by milling or broaching. Shaping machines are mainly used in tool rooms or model shops.3.2 maker CUTTING SPEEDThe cutting speed depends onThe type of material used.The amount of material removed.The kinds of tool material.The rigi dity of machine.3.4 DIFFERENCE BETWEEN WHITHWORTH AS intumesce AS QUICK RETURN MECHANISMMaximum pressure is holding the ram down the slides so that steadying is most necessary on ingress the cutIn Whitworth motion, the main pressure is in the correct place, less pressure is required in center of stroke.Slotted link motion is opposite to all the points explained above.Not withstanding the recompense stated above for the Whitworth motion, constructional difficulty make it more suitable for traversing head shaping machines and slotting machines, so that the crank motion, despite its restrictions finds universal modification for the pillar style of shaping machines.6CHAPTER 4DESIGN OF CRANK AND SLOTTED jimmy MECHANISMDesign and fabrication of crank and slotted lever mechanism and also doing the geomorphological and thermal psychoanalysis of crank shaft.

Switched LANs And Network Design Engineering Essay
Switched LANs And Ne twainrk Design Engineering EssayThe Local Area Networks (LANs) plunder inspection and repair except a small geographic line of business and there is a limitation for the total number of hosts that can be attached to a hit meshwork. In order to communicate between the hosts internet devices like hubs and switches are used. frankincense a set of LANs that are interconnected by switches will convention switched LANs and this lab is all about the cognitive process evaluation of the switched LANs.OBJECTIVEThe main goal of this lab assignment is to compare and study the performance of switched local area profits (LANs) that are implemented finished the hubs and switches. The performance study of various parameters like throughput, number of smashers, and slow down of the meshwork is done through the excuses obtained from the project implementations and the questions are answered from the simulations. executing PROCEDUREThe implementation of the switched LANs is done through OPNET IT Guru software. The software provided step by step procedures. In the first step, the communicate is created with the hub physical body having nodes from node_0 through node_15 and the hub is named as HUB_1. The Ethernet club 10BaseT, operates at 10Mbps and is used to link between the 16 hosts present in the net income. The web nodes are then individually configured for the traffic generation parameters and piece of land generation parameters attributes. As the hub configuration would send the packets received at its input to all the output lines irrespective of the destination the hub configuration network design is as shown below.The second configuration uses both the hub and the switch. Here a switch is used between the two hubs named HUB_1 and HUB_2. Each hub is connected to 8 nodes and the connection is established through the Ethernet 10BaseT link. The main difference between the hub and the switch is that the switch uses a store and forward mechanism. Thus it will forward the packets received at its input manner to the required destinations and some eons buffers due to the network traffic. The network configuration for such a combination of hub and switch is detailed in the below simulation design.The to a higher place two network configurations are analyzed for the attributes packet generation and traffic generation parameters. Both of them are similar and the packet generation occurred for e very(prenominal) blow seconds. The simulation of the configured network is run for every 2 minutes and the details are captured for further evaluation.OBSERVATIONS AND RESULTS ANALYSISThe simulation results for the configured networks are clear interpret by the graphs. Fig 3 details the traffic sent oer the hub and the hub-switch combination. From the graph we can identify the amount of traffic sent across both the configurations remained the same. Fig 4 shows the packets that are received at the destination for both the co nfigurations. From the graph we can state that the hub-switch configuration is more efficient over the hub alone configuration.The analysis of the time stand up in Fig 5 gives a clear idea about the efficiency of hub-switch configuration. The hub-switch configuration had a delay of 0.020 seconds constantly for a particular load and there is no such criterion for the hub only configuration.The collision deem in Fig 6 depicts that the collision count for the hub alone is nearly 2300 for a constant amount of time and the case with the hub and switch combination is far less which counts to nearly 900. Thus we can say from the graphs that the efficiency of hub and switch network configuration is more when compared to the hub alone network configuration.QUESTIONS AND ANSWERSQuestion 1 Explain why adding a switch makes the network perform better in terms of throughput and delay.Answer From the simulation results it is evident that a switch performs well by dividing the network into small er collision domains. Thus the throughput could be increased and also the switch provides the network bandwidth of 10 Mbps completely on each of the nodes and hence the delay of the network is reduced effectively.Question 2 We analyzed the collision counts of the hubs. Can you analyze the collision count of the Switch? Explain your answer.Answer Yes. The collision count of a switch can be analyzed with the behavior of the switch. The switch uses a store and forward mechanism. Thus it also has the capability of buffering the packets in times of network traffic. These major features of the switch would change the switch to control no collision. Thus switches are more preferred.Question 3 Create two new scenarios. The first one is the same as the OnlyHub scenario but replace the hub with a switch. The second new scenarios is the same as the HubAndSwitch scenario but replace both hubs with two switches, remove the old switch, and connect the two switches you just added together with a 10BaseT link. Compare the performance of the four scenarios in terms of delay, throughput, and collision count. Analyze the results. Note To replace a hub with a switch, right-click on the hub and assign ethernet16_switch to its model attribute.Answer The results obtained from the simulation graphs would show the throughput and time delay in the different configurations. From Fig 7, it is seen that hub and switch configuration has the increase in throughput and the hub only configuration has the least throughput among the four. The time delay between the four configurations is analyzed from the Fig 8. Here the two switches configuration has a least time delay because the usage of switches would optimize the delay in time. This is clear from the simulation graph as the time delay is around about 0.002 seconds. The analysis of collision count is al position discussed in question 2. When two switches are used by the property of the switches the collision count would be zero. Thus swit ches are the best configuration devices as compared to hubs.CONCLUSIONThus, the Switched LANs lab assignment gave a very clear vision for the choice of network configuration in a preferred location by learning the hub and switch basics. The simulation results were evident to confirm the better efficiency of a switch than a hub. Hence, the optimization of network by a switch kinda of a hub will produce cost efficiency.LABORATORY 4 NETWORK DESIGNOVERWIEWIn this lab we developed a comp eithers network having 4 departments. Since it was a small network, we used LAN model. We used OPNET Guru to simulate the network design. Once the design was done we assessed the outcome and tried to excel the network by changing some of the hardware, such as using separate servers for database, files and web vs. using one for all three of them. We also compared the same network using low vs. high meanness cables. Thus, this lab is about the optimization of network.OBJECTIVEThe main goal of this lab w as to show the learning of the fundamentals of network design. In order to doing this we took into account the users, go, and locations of the hosts.IMPLEMENTATION PROCEDURETo implement this network, we used OPNET Guru as it is one of the greatest tools in Networking. It allows one to simulate the network with any combinations of devices and protocols we have available today. First, we created an empty project and added objects Application Configuration, Profile Configuration, and a subnet as node_0, node_1 and subnet_0 respectively. Then, we configure services for applications, namely engineers, researchers, salespeople, and multimedia users. Later, we configure the subnet. Then, we create a 10-workstation star topology LAN. We do this for each of the four departments stated above. Now, we configure all the departments. Now, we configure all three servers based on different services needed for each followed by connecting each department to the subnet.Finally, we setup the network to test for statistics about the global page and run the simulation to assess the results. Later, we save the same setup as in Figure 1 above and change the background utilization to be 99 percent to create the officious Network. And run the simulation again. Finally, we echo the energetic Network and replace the low density cables with high density to observe differences. Now you are you are ready to observe the results and analyze the network.OBSERVATION AND RESULTS ANLAYSISIn figure 4.3 bellow, we observed that the result time of the busy network was much higher than the aboveboard network. Also, the system stabilizes very quick compared to the busy network.From figure 3, high density cables were very helpful in optimizing the results. With high density cables we get busy network producing a response time as if it were a simple network and it stabilizes really unbendable too.It was apparent that File server stabilizes a lot faster than both the Database waiter and the cl ear Server. Second, Database Server fluctuate the least. It became apparent that one server replacing the three server has the most load, so it mainframe computer Utilization is the most and it around higher than the Web Server alone.QUESTION AND ANSWERSQuestion 1 Analyze the result we obtained regarding the HTTP page response time. Collect four other statistics, of your choice, and rerun the simulation of the Simple and the busy network scenarios. Get the graphs that compare the collected statistics. Comment on these results.Answer From the HTTP response time for the simple and busy networks, the simple network is represented in blue and the busy network is represented in the color red. The comparison of the two time delay would result in a conclusion that the delay is much less in the simple network as compared to the busy network.We have considered four other scenarios for comparison and they are depicted in the graph as belowThe first plot shows the Ethernet delay time and fro m the figure we could notice clearly that the delay in the busy network is higher as compared to the simple network.The next plot shows the time delay comparisons of the TCP delay. We could understand that the TCP delay for the busy network is displace initially ata higher rate and then it subsides almost purge but still at at a higher pace. On the other hand the simple network has a ver low flutuating initial time delay and then it has stabilized after a period of time.The graph below represents the response time for the DB entry and the comparison between the simple and busy network shows a great deal of difference. The busy network is a bit fluctuating at the initial stage and then it commences to a stable state. But still the delay is high over here. The simple network is having a instead stable time responde from the beginning. This could be observed from the graph below.The response time for the DB Query is as shown below. In this scenario also the simple network has a quit e stable time delay and very small when compared to the initial fluctuating time delay of the busy network.Question 2 In the absorb Network scenario, study the utilization% of the CPUs in the servers (Right-click on each server and select Choose Individual Statistics ? CPU ? Utilization).Answer The CPU utilization during the Busy Network Scenario for the webserver, database server, and file server are as belowFrom the graphs above, it is obvious that File server stabilizes a lot faster than both the Database Server and the Web Server. Second, Database Server fluctuate the least if you look at the magnitude on the y-axis.Question 3 Create a new scenario as a duplicate of the Busy Network scenario. make out the new scenario Q3_OneServer. Replace the three servers with only one server that supports all required services. Study the utilization% of that servers CPU. Compare this utilization with the three CPU utilizations you obtained in the previous question.Answer It is apparent from the graph above that the one server replacing the three servers has the level best load, so its CPU Utilization is the most and it somewhat higher than the Web Server in the previous scenario. This is because the web server was using the most CPU time in the previous busy scenario.Question 4 Create a new scenario as a duplicate of the Busy Network scenario. Name the new scenario Q4_FasterNetwork. In the Q4_FasterNetwork scenario, replace all 100BaseT links in the network with 10Gbps Ethernet links and replace all 10BaseT links with 100BaseT links. Study how increasing the bandwidth of the links affects the performance of the network in the new scenario (e.g., compare the HTTP page response time in the new scenario with that of the Busy Network).Answer After making all the changes to the links, we have the following resultsFrom the results above, it is obvious that network response time is much faster and that it stabilizes really fast too. In other words, the Q4_FastNetwork is com patible to Simple Network instead of Busy Network only because we used high density cables.CONCLUSIONIn conclusion, we acquire the basics of designing a network, taking into consideration the users, services, and locations of the hosts. We learned this by using OPNET tool which is great for simulating network systems. We also, learned that using high density cables will optimize the network greatly and can even convert the response time of a network to be so fast as if it were a simple network and it stabilizes the network very fast too. We also noticed that using separate servers for different activities, such as, Database, files and web gives better performance of CPU utilization. Thus, one should consider using high density cables and separate servers for Databases, files and Web to avoid overloading just one server.

Reputation in Beowulf Essay -- Anglo Saxon Literature
The famous poet James Russell Lowell once said, Reputation is only a candle, of wavering and uncertain flame, and easily blown out, but it is the light by which the world looks for and finds merit . Reality stresses the importance to be more concerned with individual(prenominal) character than self reputation, because character beholds who you really are, while your reputation is merely what others perceive. The epic of Beowulf, written in Old English, describes the adventures of a great Scandinavian warrior of the one-sixth century. Having an outstanding reputation was an important aspect of vitality, and in the world of Beowulf it was no different. Having a well-grounded name is the same as immortality because the name will be placed in history and will be forever remembered. When introducing himself to the Danes, Beowulf was sure to mention his achievements such as the slaying of a tribe of giants and how he had impelled away countless enemies from his homeland. In his e yes, personal reputation is the most valuable possession as he took what ever means necessary in request to build a handsome repituar. After Grendels mother seeks him out to exact revenge for the crime that she believes that he has committed against her, he sees this as an prospect to further his reputation. The definition of justice in terms of Grendels mother is to seek out the one who is responsible for the death of her son and take his life as well. This is a justified reason for her to take revenge. Her only son was taken from her and the line is very thin between her and her son because they perceive events as though they were cursed. Being that they are descendants of Cain, the biblical son of Adam and Eve, the brother of Able who Cain believed was blessed by God kills Abl... ...atiently waits because she knows that the same person who stack her son would be coming after her as well. Beowulfs pursuit of the mother is nothing more than another way to build his reputation because if he had slain Grendel and it got him such recognition, slaying both ogres would raise his reputation tremendously thus bringing him even closer to his name creation secured on the cover of the history book. Him going after Grendels mother has nothing or very little to do with the fact that she is a woman, it until now has everything to do with the fame he would get and the respect that would be associated with his name.In conclusion, for Beowulf, the most important thing is reputation and the immortality that goes along with having a reputable name. Having a good reputation ensured that long after you die the birth name will be an official heroic figure in history.

The Rivals as a Parody of 18th Century :: essays research papers
A significant influencing factor on drama of the eighteenth century was the changing nature of the audience. By the middle of the eighteenth century, a straitlaced middle class audience had imparted to drama its vision of morality and disapproval of anything immoral. Comedy had become watered down and schmaltzyized. Furthermore, the audiences rejection of closed facts following the ugly reality of the French Revolution and the American War of Independence, made emotionalism and tearfulness the order of the day. Oliver Goldsmith and Richard Brinsley Sheridan were two playwrights who saw that if clowning were allowed free reign along this path of sentimentalism, it would signal the end of mirth. Both appreciated the power of pure prank and the spirit of joyous laughter and wrote plays with situations that had no call for showing the redeeming traces of vice and folly at the end, but just good healthy fun.The Rivals too denounces the hollow morality and hypocrisy associated with the sentimental attitude then prevailing, projecting its writers own ideal of a spontaneous and lively light-heartedness. The plot is based on confusion everywhere identities and multiple suitors a combination that leads to plenty of scope for truly funny situations Absolute caught in the same room with both Mrs. Malaprop and Lydia present, having to play himself for single and Beverley for the other till the presence of Sir Anthony too prevents him from doing so successfully Absolute humouring Mrs. Malaprop as himself and poking fun at her as Beverley in his line Lydias acceptance and rejection of the same man according to her romantic whims and fancies the final duel where one man has to fight two rivals virtually simultaneously. Sheridans cleverness is only underlined by the fact that in an age and the performance house in which he produced plays where spectacle, scenery and lighting had become indispensable to success, he achieved his comedy and triumph without recourse to a ny of it, merely on the strength of his own writing, wit and dialogue.Sentimentalism is found largely in the characters of Lydia and Faulkland. Sheridan attacks their traits in the overall plot and field in which he shows how a healthy deep love can be threatened by such fanciful thinking. The only redeeming feature probably in a reversal of the trend of soppy final redemptions - he shows at the end is that both are brought with a rude stupefaction down to earth following the very real possibility of losing the partners they come to know they love deeply.
