MATERIAL SOCIETY, MATERIAL THOUGHTS Ever Since Midas Lust For Gold, It

MATERIAL SOCIETY, MATERIAL THOUGHTS Ever since Midas' lust for gold, it appears to be that man has acquired a greed and appetite for wealth. Juana, the Priest, and the doctor have all undergone a change due to money. They are all affected by their hunger for wealth and inturn are the base for their own destruction, and the destruction of society. Steinbeck's "The Pearl" is a study of man's self destruction through greed. Juana, the faithful wife of Kino, a paltry peasant man, had lived a spiritual life for what had seemed like as long as she could remember. When her son Coyito fell ill from the bite of a scorpion, she eagerly turned towards the spiritual aspects of life. Beginning to pray for her son's endangered life. The doctor who had resided in the upper-class section of the town, refused to assistant the child, turning them away when they arrived at the door. Lastly they turned to the sea to seek their fortune. When Juana set sight on the "Pearl of The World." she felt as though all her prayers had been answered, if she could have foreseen the future what she would have seen would have been a mirror image of her reality. Juana's husband was caught in a twisted realm of mirrors, and they were all shattering one by one. In the night he heard a "sound so soft that it might have been simply a thought..." and quickly attacked the trespasser. This is where the problems for Juana and her family began. The fear that had mounted in Kino's body had taken control over his actions. Soon even Juana who had always had faith in her husband, had doubted him greatly. "It will destroy us all" she yelled as her attempt to rid the family of the pearl had failed. Kino had not listened however, and soon Juana began to lose her spiritual side and for a long time she had forgotten her prayers that had at once meant so much to her. She had tried to help Kino before to much trouble had aroused, only to discover that she was not competent enough to help. A hypocrathic oath is said before each medical student is granted a Doctors degree. In the oath they swear to aid the ill, and cure the injured. In the village of La Paz there lived a doctor who had earned his wealth by helping those that were ill and could afford his services. Not once in his long career would he have dared refuse to aid a wealthy lawyer or noblemen. However when Kino and the group of money hungry peasants arrived at his door with a poisoned child he had refused them entry saying "Have I nothing better to do than cure insect bites for `little Indians'? I am a doctor, not a veterinary." for the doctor had known that the peasants hadn't any money. He had been to Paris and had enjoyed the splendors of the world, and therefore he wouldn't be seen dealing with the less fortunate as he knew that the less fortunate would surely always be just that-less fortunate. However it seemed that he had been stereotypical of the less fortunate, as he soon discovered when hearing of a great pearl disco vered by the peasants who had knocked upon his door earlier that day. A hunger for wealth was what pushed him to visit the peasants house and aid their destitute son. However he had already ended Coyito's life without knowing he'd done so, for if he had administered aid to Coyito when they were first at the doctors door, Kino would have no reason to seek his fortune in the ocean, and would not be led down the road to hardships. One might think that a doctor, one who has the image of being passive, and caring should not stoop to such a level. When one is down on their luck, chances are they will turn to superstition in hope to acquire what it is that they would want to achieve. A good example of this would be a good luck charm such as a rabbit's foot. In La Paz the peasants were uneducated and

Instrumental Music and the Era of Romanticism essays

Instrumental Music and the Era of Romanticism essays The following is a comprehensive essay on the Romantic era of instrumental music. The main artistic value in the Romantic era of music was the integrity of personal feeling, and every genuine artist was expected to have a personal style (Kerman 242). Personal style is demonstrated throughout this period through the composers and their unique compositions. I will discuss and differentiate the following styles that evolved in the Romantic era; program music, symphonic poem, concert overture, and grandiose and miniature styles of music in this period. Program music is a term for non-vocal music written in association with a poem, a story, or some other literary source (Kerman 245). It can be written in association with just a highly suggestive word or two (Kerman 245). Program music was not new to the Romantic era, but it gained new importance and prestige (Kerman 245). Music could be made even more expressive by linking it to poetry and ideas (Kerman 245). Program music tells a story or it can capture a mood (Kerman 245). The following are the different genres or styles of program music from the Romantic period of instrumental program music; miniature compositions, grandiose compositions, symphonic poems, and concert overture. A concert overture resembles an opera overture; but without any following opera (Kerman 432). They were never intended for theater (Kerman 264). Berlioz wrote many concert overtures to literary works such as; plays, long poems, and novels (Kerman 264). He wrote the concert overture Hermann and Dorothea wh ich is an epic poem. The best-known and best-loved concert overtures are by Felix Mendelssohn (Kerman 264). His concert overture to A Midsummer Night's Dream was written when he was seventeen (Kerman 264/265). This was a work in sonata form that follows classical models quite clearly (Kerman 265). The piece nonetheless includes some representational features such as the music illustrating the delicate, flutter...

Healthcare Service in America Essay Example | Topics and Well Written Essays - 500 words

Healthcare Service in America - Essay Example The American Association for Labor Legislation (AALL) of 1915 was one of the legislative attempts prior to WWII that sought to get the government intervening in healthcare provision but it failed due to opposition from different quarters. The limited government involvement in healthcare provision prior to WWII is an important factor why the average American of that time was serviced poorly than American of today. This is because limited government involvement in healthcare provision Americans vulnerable to unscrupulous healthcare service providers who charged unreasonably high prices for treatment. Today, the government is deeply involved in healthcare service provision at different points of healthcare providers seeking to safeguard better service to the average American. The government regulates the manufacturing of pharmaceuticals, procurement, and administration. It also monitors and regulates the provision of healthcare insurance (Dranove, 2002). The clash between interest group s The average American who lived prior to WWII was serviced poorly than today’s average American because of a clash between different interest groups. Organizations such as the American Medical Association (AMA) and National Physician Committee (NPC) had influence enough to oppose attempts of protecting the average American. For example, in 1932 when Franklin D. Roosevelt initiated legislation for universal health care linking it to the Social Security Act, AMA and NPC successfully opposed it.

Orlando Essay Example | Topics and Well Written Essays - 1000 words - 1

Orlando - Essay Example It also explores the complex nature of cultural interpretations that emerge when roles change with emphasis on Orlando’s sudden transformation in the movie. Sally Potter’s film Orlando is a brilliant cinematic production that articulates several issues especially from a gender context as noted by Judith Butler, a cultural theorist in her essay. The film is set in the Elizabethan Age prior to Queen’s death. However, the Queen is keen to bequeath a young nobleman called Orlando a piece of land as gift to erect a castle for himself. Gender echoes significantly as observed by Butler in terms it being constituted over a certain period (Butler 519). In other words, gender is usually affirmed as a distinct identity institutionalized via repeated acts as displayed by Lady Orlando after discovering the shacking sex transformation of her husband, Orlando. It is a complex manifestation fuelled by language as the medium of communication in comprehending movements, gestures, and enactments of being. Accordingly, while Potter’s film casts the central characters as persevering against the backdrop of lawsuits especially in the pat riarchal era, the prospects of triumph are encouraging. Similarly, Lady Orlando’ lack of powers in matters concerning land rights is an epitome of identity crisis that usually afflicts societies such as the one depicted in the film. Overall, gender transformation expands possibilities for the social audience concerned with the fate and destiny of characters that include Princess Sasha, Clorinda, Favilla, and Euphrosyne. Another interesting issue emerging from the movie is tied to Butler’s assertion that the conception of gender identity is a belief inspired by appearance. In Orlando, for illustration, the clash of gender and historical situations such as the passing of Queen Elizabeth I displays the comfort in leadership that inspired Lady Orlando and her husband before his gender

Helpful and intelligent Essay Example for Free

Helpful and intelligent Essay From his hovel, the monster notices a nearby cottage occupied by the De Lacey family. He observes them cautiously from a safe distance as he now recognises mans potential to be cruel. This shows us again that the monster is constantly developing, and experiencing a variety of different emotions, such as love. Love is portrayed in Frankenstein after he watches the daily routine of the De Laceys (through a small gap in the wooden panes, previous to where the window was. This is a sign that they were not very wealthy). He discovers the sound of music through the old, blind man playing his recorder. This enchants him and he begins to admire this family. After this point his mixed emotions are so strong when watching Agathe and the old man, so strong that he cannot bear to watch the family anymore. (the music touched his heart and he felt a mixture of both pain and pleasure with love) He gradually learns more about them and increases his intelligence while doing so. He knows that they live in poverty and so his admiration grows for them, also for their wonderful appearance, as he is unaware of ugliness and deformity. He shows a caring side of himself when he became devoted to help the De Laceys by cutting wood. This monster becomes generous, helpful and intelligent. He also decided to satisfy himself with berries, nuts and roots instead of eating tastier food that they ate. This implies that this so called brute was also thoughtful. The monsters narrative tells us that he is determined character who would do anything to belong, he attempted to learn the English language to hopefully reason with the De Laceys and make them realise that he wasnt a wretched evil brute but a kind-hearted being. He was doing well until he saw his reflection in a pool of water. This part of the story (Chapter 12, page 109) is significant in tracing the change of his character because he was mortified with his appearance and became miserable. He now knew entirely why he was hated in the previous village; it was for his monstrous, alien appearance. He became aware of all the racial prejudice in the world and realised that this was the source of all his problems. Knowing this made the monster bitter at man, however he still thought of the De Lacey family as wonderful and still he wanted to restore happiness to these deserving people.  Other experiences the monster undergoes during Chapter 12 are his first realisations of the four seasons. This happens when he found that different flowers grew at different times of the year. This is another example of his developing intelligence. The next vital point in the development and change of the monster is the arrival of Safie, an Arabian woman not knowing the English language. This immensely profited him because during Safies stay with the De Laceys she began to take lessons to speak English. The monster therefore also learned the language at a rapid pace. Also in Chapter 13 we see a very sensitive side of the Monster when he is describing the nature surrounding him. (innumerable flowers, sweet to the scent and the eyes, stars of pale radiance among the moonlight woods) While Safie remains in the De Lacey household the monster begins to learn more about human nature, especially involving the love between a man (Felix) and a woman (Safie). He could not believe the ecstatic joy that Felix was in when meeting Safie, when before he seemed to be so miserable. He realises that they were both affected by different feelings, Felix by the way his cheeks flushed with pleasure and Safie by how she wiped tears from her lovely eyes. The monster observes more involving human nature when he heard of the difference of sexes and the birth and growth of children, he also heard of the different relationships between humans such as mother, father, brother and sister. This is the first stage of his life when he asks himself, where are my friends and relations? To his recollection he has had no one to care for him and remembers nothing before his first account in his narrative story. He genuinely questions what and who he is and so again we feel sympathy. The monster emotionally develops from what he learns of human nature, this occurs when Safie sings to Agatha and the old man. This deeply moves him as her voice at once brought tears of delight and joy from his eyes. He described the music as a rich cadence, swelling or dying away like a nightingale of the woods. His reaction to her singing again brings out his sensitivity.  The monster while constantly developing his knowledge of English, (now with the help of Safies lessons) still longs companionship with the De Laceys. He feels that he needs to be part of this wonderful family. Although he understands that he has been previously rejected and seen as an ugly wretch, he believes that the power of language can overcome the deformity of his face. However much he hopes that he will be accepted, he still remains conscious of his previous encounters with man. The monster remains fearful of how the De Laceys will react to him.  The next part of the monsters narrative (Chapter 14) relates little to himself but his knowledge increases of the De Laceys history, before they moved to Germany. The monster discovered such information from several letters written from Safie to Felix. Here we find that he has learnt more skills, the skills to read and write. The monster later decides to copy these letters himself to bring truth to his tale, for Victor Frankenstein. From these letters we learn an awful lot about the De Laceys, such as that previously they led wealthy lifestyles in Paris. He learnt that their wealth was lost when a Turkish merchant was condemned to death for becoming obnoxious towards the French government. This affected the De Laceys because Felix vowed to help the Turk escape and did so. (In return he was offered a reward but he declined; however he agreed to marry the merchants daughter, Safie) When learning from the De Laceys he also confirmed the relationship between the family. The old man is known as De Lacey and is father to Felix and Agatha. It was of course illegal to do this and so this resulted in the De Laceys being exiled. Knowing all this improved the monsters understanding of why the De Laceys seemed so unhappy and he now fully realised the poverty they were in.

Pushing Products through Advertising: Camera Advertising Essay

There are many ads for different products these days on market. A product needs a good ad to attract many people and make good competition. Advertising has become part of producers’ life to win consumers hearts. All cameras serve the same purpose â€Å"to make memories memorable† or it is dead. There are different types of approaches camera advertisers use to attract the buyer to the product. Companies like Canon and Nikon use techniques such as glittering generalities, testimonial, need for affiliation and aesthetic sensation as propaganda methods to attract their buyers. Maria Sharapova ranked number one player in the women professional tennis in the world, is used in a Canon commercial. This propaganda approach known as testimonial, Maria hits several tennis balls with her power shot which stick in the net to form â€Å"Maria was here†. In this commercial consumers are told that if they use a Canon power shot digital camera, they make powerful statements. Therefore, most buyers are attracted to this product because of they want to be more like her, a talented, beautiful, sports celebrity. ...

According to research done by Warr

A lot of research has been conducted and hypothesis formulated to determine whether delinquent peer associations precede delinquency or vice versa. Another concern is how age influences delinquency and the interactivity or linkage among age, peer association, and delinquency. Consequently, the aim of this paper is to bring to fore, the various researches, theories and hypothesis that invariably throw more light on this issue.According to research done by Warr (1993), delinquency escalates rapidly as individuals enter their teen years and then declines almost as rapidly as they enter their late teens and early twenties. A possible explanation for this in my opinion is that youngsters in their early teens tend to be more adventurous and experimental.They are also easily influenced to try out new habits-good or bad- since often times, they are not experienced enough to know or care about the consequences of their actions. However, as they grow older and of course learn by experience, th ey inadvertently develop a more matured and balanced approach to the everyday choices they make.On another note, the fact that a peer group that you belong to engages in unlawful activities helps to validate its relevance and the feeling that it probably is the cool thing to do. Also, because humans are creatures of habit, once they start a habit, say alcoholism, it doesn’t take long before they become addicted.From another perspective, a criminal activity, say illegal drug use, can form part of general criteria for joining some particular peer groups. This can in no small way influence youths to indulge in these activities just to win the group’s approval or endorsement.A bone of contention among researchers is which comes first between delinquency and delinquent peer association? Research by Gottfredson and Hirschi (1987), support the notion that delinquency   actually comes before delinquent peer association. Similar researches performed by Thornberry (1994), Elli ot and Menard (1996) however, offer opposing views.It is important to examine the role that age actually plays in delinquent acts. Hypothesis by Elliot and Menard (1996), show that both delinquency and delinquent peer association increase with age.A more insightful theory is the interactional theory by Thornberry (1987) that suggests that the influence of delinquent peer associations should increase during mid-adolescence and then decline gradually based on the reasoning that the hold that peer groups have on an individual is more pronounced during early stages of adolescence and less so as they grow older and commit to traditional activities like school, family, church, work etc.Still on the effects that age and delinquent peer association have on delinquency, the constant supervisory roles that teachers/guardians play in schools can douse the negative influences that delinquent peer associations can have on a young individual.However, as they advance in age and schooling, and move on to institutions of higher learning, the teachers or guardians tend to treat individuals as adults capable of making their own decisions. In other words, the supervisory roles that teachers play in the life of students reduce drastically as they advance in age and schooling. This also represents the theories expressed by Jang (1999:675).The interactional theory developed by Thornberry (1987) has been put to test but not without some loopholes. For instance, though the theory suggests that delinquent peer associations vary with age, it doesn’t specifically address the measure or category of offending. Also, a general inference tends to be made based on just one category of offending (e.g. drug offending).

Experiment on polytropic process Essay

Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation , where p is pressure, v is specific volume, c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel pressure vessel is discharged to the atmosphere while the air remaining inside expands. Temperature and pressure measurements of the air inside the vessel are recorded. These two measurements are used to produce the polytropic exponent n for the expansion process. Historical background Sadi Carnot (1796-1832) [1] in his 1824 â€Å"Reflections on the Motive Power of Heat and on Machines Fitted to Develop This Power,† examines a reciprocating, piston-in-cylinder engine. Carnot describes a cycle applied to the machine appearing in Figure 5.1, which contains his original sketch. In this figure air is contained in the chamber formed by the piston cd in the cylinder. Two heat reservoirs A and B, with temperature greater than temperature , are available to make contact with cylinder head ab. The reservoirs A and B maintain their respective temperatures during heat transfer to or from the cylinder head. Carnot gives the following six steps for his machine: 1.The piston is initially at cd when high-temperature reservoir A is brought into contact with the cylinder head ab. 2.There is isothermal expansion to ef 3.Reservoir A is removed and the piston continues to gh and so cools to . 4.Reservoir B makes contact causing isothermal compression from gh to cd. 5.Reservoir B is removed but continual compression from cd to ik causes the temperature to rise to . 6.Reservoir A makes contact, isothermally expanding the air to cd and thus completing the cycle. A decade later Clapeyron [2] analyzed Carnot’s cycle by introducing a pressure-volume, p-v diagram. Clapeyron’s diagram is reproduced next to Carnot’s engine in Figure 5.1. Claperon labels his axes y and x, which correspond to pressure and volume, respectively. We will examine two process paths in this diagram: the isothermal compression path F-K and the isothermal expansion path C-E. Since both of these processes are isothermal, pv = RT = constant. This is a special case of the polytropic process , where, for the isothermal process, n = 1, so we have the same result, pv = c. Figure 5.1 Left sketch: Carnot’s engine, after Carnot [1]. Right sketch: Clapeyron’s pressure-volume, p-v diagram, after Clapeyron [2]. For the axes in Clapeyron’s diagram x = v and y = p. The Experiments Photographs of the equipment appear in Figures 5.2 and 5.3, and a sketch of the components appears in Figure 5.4. steel pressure vessel discharge valves thermocouple conduit pressure transducer Figure 5.2 The polytropic expansion experiment at Cal Poly. thermocouples thermocouple conduit Figure 5.3 Two, Type-T thermocouples are located inside the pressure vessel, at the geometric center. Only one thermocouple is used – the other is a spare. In the photo the thermocouple conduit has been removed and held outside of the vessel. The junctions of these thermocouples are constructed of extremely fine wires (0.0254mm diameter) that provide a fast time response. Figure 5.4 The polytropic expansion experiment equipment. Pressure measurements come from the pressure transducer tapped in to the pressure vessel shown in Figure 5.4. The transducer is powered by the unit labeled â€Å"CD23†, which is a Validyne [3] carrier demodulator. The fine wire thermocouple is described in the Figure 5.3 caption. Both thermocouple and pressure signals feed into an Omega [4] flatbed recorder. The three discharge valves on the right side of the vessel have small, medium, and large orifices. These orifices allow the air inside the vessel expand at three different rates. The pressure vessel is first charged with the compressed air supply. This causes the air that enters the vessel to initially rise in temperature. After a few minutes the temperature reaches equilibrium at which time one of the discharge valves is opened. Temperature and pressure are recorded for each expansion process. These data are then used to compute the polytropic exponent n for each process. It is important to note that the temperature and pressure of the air inside the vessel are measured, not the air discharging from the vessel. Data Pressure and temperature data, for the three runs, are provided in the EXCEL file â€Å"Experiment 5 Data.xls.† Analysis In many cases the process path for a gas expanding or contracting follows the relationship (5.1) The polytropic exponent n can theoretically range from . However, Wark [5] reports that the relation is especially useful when . For the following simple processes the n values are: isobaric process (constant pressure)n = 0 isothermal process (constant temperature)n = 1 isentropic process (constant entropy)n = k ( k=1.4 for air) isochoric process (constant volume)n = ï‚ ¥ In our experiment the steel pressure vessel is initially charged with compressed air of mass . Next, the vessel is discharged and the remaining air mass is . This final mass was part of the initial mass and occupied part of the volume of the vessel at the initial state. Thus expanded within the vessel with a corresponding change in temperature and pressure. Therefore mass can be considered a closed system with a moving system boundary and the following form of the first law of thermodynamics applies (5.2) If the system undergoes an adiabatic expansion , and if the work at the moving system boundary is reversible. Furthermore, if we consider the air to be an ideal gas with constant specific heat. With these considerations the first law reduces to (5.3) Using the ideal gas assumption and differentiating this equation gives (5.4) Substituting Equation 5.4 into 5.3 and using the relationships and gives Separating variables and integrating this equation, , yields (5.5) which is a special case of the polytropic relationship given by Equation 5.1, with n = k. It is important to note that in the development of Equation 5.5 the expansion of inside the pressure vessel was assumed to be reversible and adiabatic, i.e. an isentropic expansion. In our experiment the adiabatic assumption is accurate during initial discharge. However, the reversible assumption is clearly not applicable because the air expands irreversibly from high pressure to low pressure. Therefore we anticipate our data to yield . Two approaches are used to determined the polytropic exponent n from the data: 1. Equation 5.1 can be written as , which is a power law equation. In EXCEL, a plot of p versus v and a power law curve fit using TRENDLINE will disclose n. 2. Equation 5.6 (subsequently developed) may be used with only two states to determine n. Here is the outline of the development of Equation 5.6. We start with , which also can be expressed as and combine this with the ideal gas law to obtain (5.6) The temperatures and pressures in Equation 5.6 are all absolute and the subscripts 1 and 2 represent the initial and final states. Required 1. Pressure and temperature data are provided for all three runs in â€Å"Experiment 5 Data.xls.† Use the ideal gas law, pv = RT, to compute v corresponding to each p. Use SI units: m3/kg for v and Pa for p. 2. Plot p versus v and find n: For each run, on a separate graph, plot p [on the ordinate (vertical) axis] versus v [on the abscissa (horizontal) axis]. Use linear scales. Determine the polytropic exponent n for each run using a TRENDLINE power curve fit. Also find the correlation coefficient for each curve. (Be aware that the TRENDLINE power curve fit will give , where y = p, x = v and a and b are constants.) Plot all three runs on a single graph and find n for the combined data. 3. Derive Equation 5.6. 4. Find n for each run using Equation 5.6, where states 1 and 2 represent the beginning and ending states, respectively. 5. In a single table show all of the n values. 6.

Theater Thesis essays

Theater Thesis essays You dont need to be the best singer, dancer, or actor to succeed in theater. You just need to feel like you are, whether you have to pretend or not. You cant go on stage with a bad attitude or else you will end up leaving the stage with an even worse attitude. What I mean is, if you think you are going to perform poorly then most likely you will and you will feel embarrassed when you are finished. To be cast in a musical you must be confident with singing, dancing, and obviously, acting. Not everyone can be the best singer but everyone can definitely try to be. Its hard to perform in front of people period, but singing is even harder. This is because there is a fine line between good and bad when it comes to singing. Youre either really good or not so good. If you think youre bad, than other people around you will think so too. If you believe that you can sing well other people will think you sing well. You dont need professional help or lessons; you just need your own confidence. Dancing on stage, in front of people can also be harsh like singing. Dancing requires physical strength as well as mental strength. Unlike singing you need to at least have some experience with dance. If you dont, I suggest that you practice, practice, practice. Even if its once or twice a week, it will help. You dont need to go to classes, just put on the radio and make up some danced moves. When youre onstage dancing, be loose. What I mean is, if youre arms arent doing anything, wave them around a bit. And if you cant remember a dance step, make one up! Its better then nothing! These things should help you during your performance. Heres the big one, acting. I suppose over all theater is based on acting and if youre interested in it you should be familiar with it. Drama is hard work and I think the hardest part is memorizing you script and lines. W ...

Brazilian Democratic Transition And Consolidation

Brazilian Democratic Transition And Consolidation Brazil, which is the largest country in South America and fifth largest country in the world, is also a political and economic leader in its continent. However, among the many nascent Latin American democracies, Brazil’s road to democracy was the most challenging (Linz and Stepan, 1996, p 166). Its democratization (1974-89) followed a cyclical pattern which alternated back and forth between quasi-democratic and authoritarian systems (Huntington, 1991, p 41). After a brief period of electoral democracy in the 1930s, military coups took control of the nation. The next three decades witnessed Brazil’s long authoritarian rule that was governed by a series of stable but harsh dictatorial regimes. In the 20th century, Brazil embarked on the path to electoral democracy, which was led by Vargas, the elected President. However, his rule plagued Brazil with several rebellions caused by military officers, the spread of communism across the country, and brutal tortures by governme nt agents. Thus, the short period of democracy ended and Vargas established a populist dictatorship. In 1945, military coup supported by the Brazilian oligarchy finally overthrew the ineffective and harsh leader. Brazil then plunged into a long authoritarian rule from 1964 to 1985, in which the military government held power and democratized Brazil through five major stages (Codato, 2006). It was this period of uncertainty and unrest caused by violent prolonged military dictatorship that created the climate for political compromise and democratic obligation. Causes for the breakdown of authoritarianism such as splits in the military led to the demand for re-democratization in Brazil. Democratization finally occurred in 1974 and coincided with the ‘Third Wave’ of democracy. One will be surprised and wonder how Brazil’s long period of authoritarianism under the reign of three capable leaders, Branco, Silva, and Medici’s leadership sparked a possible shift to a democracy. What factors pressured each successive military leader to concede to democratization? After a long military dictatorship, what caused the next administration, Geisel, to democratize Brazil? Finally, to what extent has democracy been consolidated? This paper will attempt to answer the above questions. I will first give a contextual knowledge about Brazil’s political transition which occurred in five stages, over the span of thirty years. Next, I will explain the reasons that caused the breakdown of authoritarianism in Brazil. Finally, I will evaluate the extent to which democracy in Brazil is consolidated based on its obstacles and threats, and suggest ways in which the democracy can be stabilized. History of Brazil’s Political Transition Establishing military dictatorship The first stage of Brazil’s political transition corresponds to the Castello Branco and Costa e Silva administrations (March, 1964 – December, 1968). The military ceased it s leadership in 1961 when vice president Joà £o Goulart resigned from presidency. He resigned with hopes of being reinstated again by popular demand, but was denied by the military’s fear of him being a communist. Following his resignation, the regime encountered difficulties in finding a new leader as no civilian politician was suitable for the existing revolutionary factions in governance. After fifteen days, Branco became the new president and managed to reform the political-economic system (Hudson, 1997). Being anti-Goulart and disapproving of his ruling methods, Branco rejected the extension of his presidency beyond Goulart’s term, or the institutionalization of the military’s power.

The film Sky Captain and the World of Tomorrow Essay

The film Sky Captain and the World of Tomorrow - Essay Example The motion picture comes into view in a stylized edition of the 1930s which is a plot where the entire world is on a big screen. The movie is about a person named Joe "Sky Captain" Sullivan (Jude Law) who is a sturdy explorer and comes to save the city in his personal aircraft at the time when the people need him. Polly Perkins (Gwyneth Paltrow) is an intrepid journalist for The Chronicle, as well as a Joe’s past lover. Dex Dearborn (Giovanni Ribisi) is Joe’s assistant and Franky Cook (Angelina Jolie), is the commander of British aircraft who provides a helping hand to Joe every time he needs it. The whole movie revolves around the good and the bad people fighting and the battle starts when an army of colossal robots attack in Manhattan and start trampling with things all over the place. And then the hero Sky Captain enters and saves the day. It turns out that the assaults of the robots are associated with the disappearance of six famous scientists, a story that Polly Perkins is scrutinizing into. All of the clues point to Dr. Totenkopf, but his place is unknown. When Dex is apprehended, Joe comes to a conclusion to go after him, and Polly makes a decision that she wont be left behind and goes along with Joe. Saving the world becomes an almost inferior thought then saving their friend. The opening scenes of the movie are very fascinating as advanced technology is used which makes the movie more interesting to watch and much has been said about how the chief part of the movie was acted in front of blue screens (computer generated backgrounds were later added).It is the first movie ever which is shot completely adjacent to a blue screen and the scenes were added later. The technology is used sensibly and in a positive way to make the movie more real to its viewers. Another very good way in using the technology and the best part of the movie is the additional digital improvement which permits the late Sir Laurence Olivier (who died in 1989) to give an
