Electromagnetic radiation Essay Example for Free

Electromagnetic radiation Essay Electromagnetic waves are disturbances caused by the oscillation of charged particles. It consists of two parts, an electric field and a magnetic field oscillating perpendicular to each other. The wave is self-sustaining, and propagates at a direction perpendicular to both the electric field and magnetic field. There is a whole spectrum of electromagnetic waves. The ones with the longest wavelengths (range: 1 cm-1km) are the radio waves. After the radio waves, microwaves have the next longest wavelength (range: 1mm-10cm). Then, we have the infrared waves (range: 1 µm-1mm), followed by light (range: 400nm-700nm), ultraviolet rays (range: 1nm-100nm), x-rays (range: 0. 1nm-10nm), and gamma rays, which have the shortest wavelengths amongst the different electromagnetic radiations (range: 0. 01nm-0. 1nm). b. How you determine the temperature, composition, and motion of an object from its light spectrum? Different elements emit and absorb light waves differently. Hence, when viewed through a spectroscope, different elements will have different spectral patterns. The object’s composition is obtained from noting which spectral lines are present or absent. We can also determine the density of the object depending on the amount of lines present in the spectrum. The more lines and the more continuous the spectrum, the denser is the material. On the other hand, the temperature of the object will affect the shapes spectral lines emitted by the object. If objects have high temperatures, their spectral lines will be broader, that is, it is spread over more frequencies than if it had lower temperature. To determine temperature, Finally, the Doppler Shift tells us the motion of the object, whether it is moving away or toward us, and with what speed. When the observed object is moving toward us, the spectral lines we observe occur at shorter wavelengths when we compare it to those measured in the laboratory. This is called â€Å"blueshifted. † On the other hand, if the object is moving away from us we observe the lines to occur at longer wavelengths. In this case we say that the lines are â€Å"redshifted. † The amount of shifting will determine the speed of motion. c. In what way do astronomers infer that the Sun’s energy comes from nuclear fusion reactions? How do we know it does not come from chemical burning? Even though both nuclear fusions and chemical reactions result in the release of energy, nuclear fusions release much more energy than chemical reactions. This is due to the nature of each reaction. Given that the energy that the sun produces is extremely high, it is impossible that chemical reactions are fuelling it, for if that were the case, then the sun will not be producing enough energy to sustain life on Earth. If it were chemical reactions powering it, it would be producing roughly one-millionth of the energy it is producing now. d. Explain how the Sun produces energy by nuclear fusion. Because of the amount of matter present in the sun, it is in danger of imploding. What keeps this from happening, however, is the nuclear fusion that occurs in its core, which is so hot because of the pressure from its mass that is being pulled inwards by gravity. In the core, hydrogen nuclei are forced to come together. This fusion creates helium-4 and energy. Since the resulting He-4 atoms are less massive than the initial hydrogen atoms that fused together, the missing mass is what was transformed into energy. This is best explained by the most famous equation in Physics, E=mc2, which states the equivalence of mass and energy. e. When we look at stars in the sky, we see a wide range of brightness. Explain the factors that would make one star appear brighter than another. There are two factors that affect the brightness of stars in the sky. The first one is the inherent characteristic of the star, which dictates how absolutely bright or luminous it will be. The second factor that affects the way we see stars is their distance from the earth. The farther they are, the dimmer they would appear. This is because the light they emit would need to pass through interstellar matter that could disperse, absorb or reflect the light in different directions. f. Compare the Sun with other stars. The Sun is called such by virtue of its position, that is, it is in the center of the solar system. Technically, however, the sun is also a star. It differs from other stars in its size, temperature, age, and color. The Sun is a dwarf star, about 4. 5 billion years old, and is classified as â€Å"yellow,† which means that it has an average temperature of about 6000 K. Hotter stars are classified as blue-white, while cooler stars are red. g. Consider a star at the upper part of the main sequence (label it Star A) and a star in the lower part of the main sequence (label it Star B). Which is: 1) Larger? Star A 2) More luminous? Star A 3) More massive? Star A 4) Hotter? Star A h. Compare the life spans of low mass stars and high mass stars. Explain why they are different. The life span of low mass stars is longer than the life spans of high mass stars. The reason for this is that the higher the mass of the star, the more hydrogen is needed to undergo fusion to keep the star from collapsing under its own gravitational force. i. What would an imaginary terrestrial observer see as the Sun runs out of hydrogen? If life is confined to Earth when this happens, would life perish from heat or from cold? Explain. As the Sun runs out of hydrogen fuel, it will start consuming helium. This leads to the sun increasing in radius, eventually turning it into a red giant. When this happens, the sun will grow so large that it can engulf the earth. Life on Earth would perish from extreme heat. When the helium runs out, however, the sun will shrink to a white dwarf. The reason for this is that the sun is too small to continue burning elements larger than helium. j. What kind of stars eventually become white dwarfs? What kind eventually become supernovae? What will be the ultimate fate of the Sun? Why? A white dwarf is an extremely dense star, with the mass of the sun and the size of the earth. It is composed of the remnants of stellar matter, which is mostly carbon and oxygen. In order to turn into a white dwarf, stars need to have a size of about 0. 07-10 times that of the sun. On the other hand, a supernova is formed when a massive star consumes all of its nuclear fuel and thus collapses under its gravitational field. Because of the high gravitational force that causes its collapse, the dead star suddenly explodes. A star that is about 8-10 times more massive than the sun will end its life as a supernova. The ultimate fate of the sun is to become a white dwarf. The reason for this is that the sun is not very massive to turn into a supernova, thus lacking the critical mass that would cause it to collapse under its own weight.

Types Of Narcissistic Personalities Philosophy Essay

Types Of Narcissistic Personalities Philosophy Essay Like all of us, narcissists are human beings. As such, all narcissists are not alike. They are different among themselves. We take up Millons report first. In the year 1969, Millon has divided the narcissistic personalities into two subtypes: (1) Passive independent, or narcissistic personalities, who are confident of their self-worth and who feel they need to be merely themselves to justify being content and secure; (2) active-independent, or antisocial personalities, who struggle to prove themselves, who visit on their rights and will be harsh and ruthless when necessary to retaliate or gain power over others. For the narcissistic type, self-esteem in based on a blind and naÃÆ' ¯ve assumption of personal worth and superiority. For the antisocial type, it seems from distrust, an assumption that others will be humiliating and exploitive. To these personalities, whose independence from others takes on an active and angry character, self-determination is a protective maneuver: it is a means of countering, with their own power and prestige, the hostility, deception, and victimization they anticipate from others. Although both passive na rcissistic and active independents (antisocial) devalue the standards and opinions of others, finding gratification primarily within themselves. Their life histories and the strategies they employ for achieving their needs are potentially different. After intermittent interests in narcissism Millon (1977, 1987, and 1994) has presented the following four types of narcissistic personalities: (i) Unprincipled narcissist (ii) Amorous Narcissist (iii) Compensatory Narcissist (iv) Elitist Narcissist i) The Unprincipled Narcissist The unprincipled narcissist has been seen more often in drug reha ­bilitation programs, centers for youth offenders, and in jails and prisons. Although these individuals often are successful in society, keeping their activities just within the boundaries of the law, they enter into clinical treatment rather infrequently. The behavior of these narcissists characterized by an arrogant sense of self-worth, an indifference to the welfare of others, and a fraudulent and intimidating social manner. There is a desire to exploit others, to expect special recognitions and considerations without assuming reciprocal responsibilities. A deficient social conscience is evident in the tendency to flout conventions, to engage in actions that raise questions of personal integrity, and to disregard the rights of others. Achievement deficits and social responsibilities are justified by expansive fantasies and frank pre ­varications. Descriptively, we may characterize this narcissist as devoid of a superego that is ev ­idencing an unscrupulous, amoral, and deceptive approach to relationships with others. More than merely disloyal and exploitive, these narcissists may be found among societys con men and char ­latans, many of whom are vindictive and con ­temptuous of their victims. The features that are clearly se en in the unprincipled narcissist support the conclusion that these individuals are an ad ­mixture of both narcissistic and antisocial per ­sonality characteristics. The unprincipled narcissist evidences a rash willingness to risk harm and is notably fearless in the face of threats and punitive action, Malicious tendencies are projected outward, precipitating fre ­quent personal and family difficulties, as well as occasional legal entanglements. Vengeful gratifica ­tion is often obtained by humiliating and dominat ­ing others. These narcissists operate as if they have no principles other than exploiting others for their personal gain. Lacking a genuine sense of guilt and possessing little social conscience, they are oppor ­tunists and charlatans who enjoy the process of swindling others. In a game narcissists enjoy play ­ing, they outwit others and hold them in contempt owing to the ease with which they can be seduced. Relationships survive only as long as the narcissist has something to gain. People are dropped with no thought to the anguish they may experience as a consequence of the narcissists careless and irre ­sponsible behavior s. In many ways, the unprincipled narcissist is sim ­ilar to the disingenuous histrionic. They share a de ­vious and guileful style, plotting and scheming in their calculations to manipulate others. However, the disingenuous histrionic continues to pursue the strong need for attention and love, characteristics not present in the narcissist where there is a basic self-centeredness and an indifference to the atti ­tudes and reactions of others. The unprincipled narcissist preys on the weak and vulnerable, enjoy ­ing their dismay and anger; the histrionic, by contrast, seeks to hold the respect and affection of those they dismiss in the pursuit of love and admiration. Unprincipled narcissists display an indifference to truth that, if brought to their attention, is likely to elicit an attitude of nonchalant indifference. They are skillful in the ways of social influence, are capable of feigning an air of justified innocence, and are adept in deceiving others with charm and glibness. Lacking any deep feelings of loyalty, they may successfully scheme beneath a veneer of politeness and civility. Their principal orientation is that of outwitting others, getting power and exploiting them before they do it to you. They often carry a chip-on-the shoulder atti ­tude, a readiness to attack those who are distrusted or who can be used as scapegoats. A number of these narcissists attempt to present an image of cool strength, acting tough, arrogant, and fearless. To prove their courage; they may invite danger and punishment. But punishment only verifies their unconscious recognition that they deserve to be punished. Rather than having a deterrent ef ­fect, it only reinforces their exploitive and un ­principled behaviors. ii) The Amorous Narcissist The distinctive feature of this narcissistic person ­ality type is an erotic and seductive orientation, a building up of ones self-worth by engaging mem ­bers of the opposite gender in the game of sexual temptation. There is an indifferent conscience, an aloofness to truth and social responsibility that, if brought to the amorous narcissists attention, elicits an attitude of nonchalant innocence. Though totally self-oriented, these individuals are facile in the ways of social seduction, often feign an air of dignity and confidence, and are rather skilled in deceiving others with their clever glibness. These narcissists are skillful in enticing, bewitch ­ing, and tantalizing the needy and the naive. Al ­though indulging their hedonistic desires, as well as pursuing numerous beguiling objects at the same time, they are strongly disinclined to be ­come involved in a genuine intimacy. Rather than investing their efforts in one appealing person, they seek to acquire a coterie of amorous objects, invariably lying and swindling as they weave from one pathological relationship to another. The qual ­ities just outlined are strongly suggestive of the observation that these narcissistic types possess numerous characteristics that are primary among histrionic personalities. Although a reasonably good capacity for sex ­ual athletics sustains the vanity of many individu ­als, narcissists or not, the need to repeatedly demonstrate ones sexual prowess is a preeminent obsession among amorous subtypes. Among these personalities are those whose endless pursuit of sexual conquests is fulfilled as effectively and frequently as their bewitching style promises. Others, however, talk well, place their lures and baits extremely well-until they reach the bed ­room door; maneuvering and seduction is done with great aplomb, but performance falls short. For the most part, the sexual exploits of the amorous narcissist are brief, lasting from one af ­ternoon to only a few weeks. Some amorous narcissists are fearful of the opposite sex, afraid that their pretensions and ambitions will be exposed and found wanting. Their sexual banter and seductive feelings of inadequacy. Although they seem to desire the. affections of a warm and intimate relationship, they typically feel restless and unsatisfied when they find it. Having won others over, they seem to need to continue their pursuit. It is the act of exhi ­bitionistically being seductive, and hence gaining in narcissistic stature, that compels. The achieve ­ment of ego gratification terminates for a moment, but it must be pursued again and again. Not infrequently, amorous narcissists leave be ­hind them a trail of outrageous acts such as swin ­dling, sexual excesses, pathological lying, and fraud. This disregard for truth and the talent for exploitation and deception are often neither hos ­tile nor malicious in intent. These characteristics appear to derive from an attitude of narcissistic omnipotence and self-assurance, a feeling that the implicit rules of human relationships do not apply to them and that they are above the responsibili ­ties of shared living. As with the basic narcissistic pattern, individuals of this subtype go out of their way to entice and inveigle the unwary among the opposite sex, remain coolly indifferent to the wel ­fare of those whom they bewitch, whom they have used to enhance and indulge their hedonistic whims and erotic desires. Caring little to shoulder genuine social respon ­sibilities and unwilling to change their seductive ways. amorous narcissists refuse to buckle down in a serious relationship and expend effort to prove their worth. Never having learned to control their fantasies or to be concerned with matters of social integrity they will maintain their bewitching ways, if need be by deception, fraud, lying, and by charming others through craft and wit. Rather than apply their talents toward the goal of tangible achievements or genuine relationships, they will devote their energies to construct intricate lies, to cleverly exploit others, and to slyly contrive ways to extract from others what they believe is their due. Untroubled by conscience and needing nourishment for their overinflated self-image, they will fabricate stories that enhance their worth and thereby succeed in seducing others into supporting their excesses. Criticism and punishment are likely to prove of no avail since these narcissi sts quickly dismisses them as the product of jealous inferiors. iii) The Compensatory Narcissist Compensatory narcissists deviate in a fundamental way from other narcissistic subtypes as well as from the prototypal narcissist. The origins that un ­dergird their overtly narcissistic behaviors derive from an underlying sense of insecurity and weak ­ness, rather than from genuine feelings of self-con ­fidence and high self-esteem. Beneath their surface pseudo-confidence, the posture they exhibit pub ­licly, this narcissist is driven by forces similar to those who overtly display characteristics more akin, to the negativistic and avoidant personalities. The compensatory narcissist represents patients who are labeled narcissistic by those in the psy ­choanalytic community in that they have suffered wounds in early life. Many have been exposed to experiences akin to the negativistic, avoidant, and antisocial types. In essence, these personalities seek to make up or compensate for early life depri ­vations. They are similar to the antisocial, but com ­pensatory narcissists seek to fill their sense of emptiness by creating an illusion of superiority and by building up an image of high self-worth, rather than by usurping the power and control that others possess or by accumulating material possessions. Compensatory narcissists need others to fulfill their strivings for prestige. Their motive is to en ­hance their self-esteem, to obtain and to store up within the self all forms of recognition that will glorify their public persona. Much to the annoy ­ance of others, these narcissists act drunk as they recount their successes and record for others to acknowledge all forms of even minor public recogni ­tion. In effect, these narcissists actively worship themselves; they are their own god. As this inflated and overvalued sense of self rises evermore highly, narcissists look down on others as devalued ple ­beians. More and more, they acquire a deprecatory attitude in which the achievements of others are ridiculed and degraded. Life is a search for pseudo-status, an empty se ­ries of aspirations that serves no purpose other than self-enhancement. This search for these vacuous goals may begin to run wild, resting from its very foundation on an unsure sense of self  ­value that has but little contact with tangible achievements. Instead of living their own lives. they pursue the leading role in a false and imagi ­nary theater. Nothing they achieve in this pursuit relates much to reality. Their tenacious aspira ­tions for glory may impress the naive and the grateful, but they possess little of a genuine or ob ­jective character. Should these pursuits lose their grounding in reality, becoming more and more an imaginary world, peopled with self and others as in a dream, compensatory narcissists begin to deceive themselves in a manner not unlike the fanatic paranoid. If we draw a line between these two per ­sonality subtypes, we would see that the compen ­satory narcissist strives for prestige in a world composed of real people. When reality recedes and fantasy comes more to the fore, we see the fan ­atic who acts out aspirations in solitude. One comes to the stage in front of others, be it in the form of exaggeration and boasting; the other stands alone in an inner world, a pseudo-commu ­nity, as Cameron (1963) has phrased it, where imagination has substantially replaced reality. Owing to the insecure foundations on which heir narcissistic displays are grounded, compensatory narcissists are hypervigilant, to use a term employed by Gabbard (1994). What is meant here is they are exquisitely sensitive to how others react to them, watching and listening carefully for any critical judgment, and feeling slighted by every sign of disapproval. Although not delusional, as are their paranoid counterparts, these narcissists are prone to feel shamed and humiliated, especially hyperanxious and vulnerable to the judgments of others. They know that they are frauds at some level, pretenders who seek to convey impressions of being of higher standing than they know is truly the case. Despite this awareness, they do not act shy and hesitant, as would seem likely. Instead, they, submerge and cover up their deep sense of inade ­quacy and deficiency by pseudo-arrogance and su ­perficial grandiosity. . iv) The Elitist Narcissist Reich (1949) captured the essential qualities of what we are terming the elitist narcissist when he described the phallic-narcissist character as a self-assured, arrogant, and energetic person often impressive in his bearing. . . . and are iII ­suited to subordinate positions among the rank and file. As with the compensatory narcissist, elitist narcissists are more taken with their in ­flated self-image than with their actual self. Both narcissistic types create a false facade that bears minimal resemblance to the person they really are. Compensatory narcissists, however, know at some level that they are a fraud in fact, and that they put forth an appearance different from the way they are. By contrast, elitist narcissists, perhaps the purest variant of the narcissistic style, are deeply convinced of their superior self-image although it is grounded on few realistic achievements. To elit ­ists, the appearance of things is perceived as ob ­jective reality; their inflated self- image is their intrinsic substance. Only when these illusory elements to their self-worth are seriously under mined will they be able to recognize, perhaps even to acknowledge, their deeper shortcomings. As a consequence of their sublime self-confi ­dence, elitists feel quite secure in their apparent superiority. They achieve this in part by capturing the attentions of others and making them take note of the supposed extraordinary qualities. Most everything these narcissists do is intended to per ­suade others of their specialness, rather than to put their efforts into acquiring genuine qualifications and attainments. They feel privileged and empow ­ered by virtue of whatever class status and pseudo  ­achievements they may have attained. Most are upwardly mobile, seeking to cultivate their sense of specialness and personal advantage by associat ­ing with those who may possess genuine achieve ­ments and recognition. Many elitists will create comparisons between themselves and others, turn ­ing personal relationships into public competitions and contests. Unrivaled in the pursuit of becoming number one, the grounds for this goal are not de ­termined by genuine accomplis hments, but by the degree to which they can convince others of its re ­ality, false though its substance may be. As just described, many narcissistic elitists are social climbers who seek to cultivate their image and social luster by virtue of those with whom they are affiliated. To them, it is not the old chestnut of guilt by association, but rather that of status by association. Idolizing public recognition, narcis ­sists of this type get caught in the game of one-up ­manship, which they strive vigorously to win, at least comparatively. Status and self-promotion are all that matter to narcissistic elitists. To be celebrated, even famous, is what drives them, rather than to achieve substantive accomplishments. In whatever sphere of activity matters to them, they invest their efforts to advertise themselves, to brag about achievements, substantive or fraudulent, to make anything they have done appear to be won ­derful, better than what others may have done, and better than it may actually be. By making excessive claims about themselves, these narcissists expose a great distance between their actual selves and their self-presentations. In contrast to many narcissists who recognize this disparity, elitists are convinced and absolute in their belief in self. Rather than backing off, with ­drawing, or feeling shame when slighted or re ­sponded to with indifference, elitist narcissists speed up their efforts all the more, acting increas ­ingly and somewhat erratically to exhibit deeds and awards worthy of high esteem. They may present grandiose illusions about their powers and future status; they may puff up their limited ac ­complishments; they may seek competitively to outdo those who have achieved in reality. By the persistence and social intrusiveness of their behaviors, narcissistic elitists may begin to alienate themselves from others, and the admira ­tion they seek. Insulating themselves from signs of painful indifference and psychic injury, they may try to distance or screen out negativistic and judg ­mental responses. Some may become overtly hos ­tile, acquiring characteristics of the querulous paranoid, quickly losing the remaining elements of their former charm and cleverness, becoming increasingly contemptuous of those whom they feel are treating them so shabbily. Still believing themselves to be special persons, these elitists see little need to listen or follow the dictates of any ­one else. They may begin to react with outright anger and irritability, convinced that they need no one. As these self-protective beliefs and actions gain in their defensive and negative tone, the elit ­ist narcissist comes to be seen as an undesirable and embarrassing person, a touchy and inflated character whom others wish to shun. Burstens four personality variants Bursten (1973-1982) presented four personality variants within the narcissistic grouping, speaking of them as the craving, paranoid, manipulative, and phallic types. He refers to the Craving variety as changing, demanding, often pouting and whining. These labeled paranoid narcissists correspond with general descriptions of the paranoid personality. Manipulative narcissists encompass a large segment of what are referred to as antisocial personalities in the DSM The fourth subtype, phallic narcissistic, describes patients who are exhibitionistic, reckless, cold, and arrogant. In seeking to contrast borderline from narcissistic personalities, Bursten makes references to the distinction as bearing on the cohesiveness of self. Elaborating this distinction, he speaks of the narcissistic personality as comprising (1982): à ¢Ã¢â€š ¬Ã‚ ¦.a group of people whose sense of self is sufficiently cohesive that they do not suffer form these types of fragility problems. The striking feature of this cluster of personality types centers around self-esteem. They maintain an intense interest in themselves and harbor both grandiose fantasies, albeit not to a delusional extent, and the need to associate with powerful figures. When one frustrates their verity or their need for an ideal parent, they become dysfunctional they suffer sever disappointment depression, rage, and hypochondriacs. They may even have floating episodes of confusion, but such mental disinte gration is very brief and does not have the prominence and the persistence of people whose personalities fall in the borderline cluster. Cohesiveness of their sense of self is maintained by the intensity of their narcissistic focus on themselves. (p.414)

Lumumba: Race and Revolution :: essays papers

Lumumba: Race and Revolution In the French film entitled Lumumba, director Raoul Peck recreates the revolutionary struggle of Patrice Lumumba, the newly elected Prime Minister of The Congolese Republic. In the movie, we do not see much of the independence struggle against the Belgian government, but we begin to see the reconstruction of the African state in African hands. While no one ever claimed that decolonization was easy, maybe this particular example can best be explained by Fanon’s simplified little quip â€Å"decolonization is always a violent phenomenon. † In this paper, I will seek to locate where this post-colonial violence is located in discourses regarding race, class and gender. Particularly, I will look at the representations of race and class, and the lack of the representation of gender, in order to draw conclusions about the nature of representation and the effects this has on anti-colonial film. Locating the violence within the anti-colonial struggle may be harder than it seems. One can easily note the physical and sexual violence brought upon the people (black and white) of Congo after independence, but we must locate the other forms of violence in order to bring the entire story of Patrice Lumumba to light. The director’s attempt at bringing the story of Patrice Lumumba to the â€Å"silver screen† had political intentions. It had intentions of breaking post-colonial hegemonic forces that portrayed Lumumba as a nationalist dictator. In regards to race and class in Congo, I will refer to the work of Franz Fanon, in particular his book entitled The Wretched of the Earth. In this book Fanon develops a theory of â€Å"dual citizenship† required by the colonizers in order to validate the colonization process. We have to view the movie Lumumba as being part of the anti-colonial discourse in the history of the Congo but also as a historical fiction produced in 21st century France. In viewing this movie, we must locate race and class and the intersection between the two, as this is constantly the case in post-colonial states. We must also understand the exclusion of gender from revolutionary discourses as being part of patriarchy that is not challenged in certain revolutions. The exclusion of gender equality from what Lumumba struggled for is where there is a certain patriarchy, and this kind of patriarchy is evident in almost all revolutionary anti-colonial writing.

Impacts of Urban Tourism Essay -- Economics Society Tourism

During the past few decades, traveling has greatly increased. Purposes of travel vary, some travel for business, some for leisure, some for the experience of different cultures, some for specific interests, or just for the pursuit of entertainment. More than half of the globe's population now lives in urban areas, these places are now the world's stage for many civilizations. They are centers of arts, entertainment and food, gateways to traditional customs and modern society, focal points for commerce, industry and finance, culture and people, icons and architecture, uniqueness and unity, and of course they give tourists a chance to experience diversity and creativity. However, to know what the city's strategies to attract the attention of tourist, there are cretin elements of urban tourism need to identify that lead to attract visitors to a city. Tourism is often associated with traveling to places away from home. Tourism has a big impact on the economic growth of some countries, which define the shape of their cities by producing different sectors like historic districts, convention centers, museums, malls, hotels, restaurants, and the list can be endless. Furthermore, tourism elements have been developed by cities for a variety of reasons including: situating themselves in the world by drawing a positive image and attracting visitors and for their money. As a result, by defining the primary and secondary elements in the tourist bubble, it could determine what effect urban tourism has on cities. Therefore, primary elements include: cultural facilities (museums and art galleries, theaters, cinemas, concert halls and convention centers), sport facilities, amusement facilities (night clubs, casinos and festivals), p... ...Marketing cities for Tourism†, page 54 Houston, and Sydney opera house all these icons play a big role in marketing their cities to attract tourists to visit. Overall, travel can change the spiritual as well as the physical existence of both visitors and host, therefore urban tourism refers to the consumption of city spectacles and cultural amenities by visitors. Also, it is important to point out that the tourist elements developed by most cities are portraying a product â€Å"the city† to promote it for consumers â€Å"visitors† in order of stimulating the urban economy.

Edgar Allan Poe :: essays research papers fc

Edgar Allan Poe 1809-1849 In personal appearance, Poe was a quiet, shy-looking but handsome man; he was slightly built, and was five feet, eight inches in height. His mouth was considered beautiful. His eyes, with long dark lashes, were hazel-gray. Edgar Poe was born in 1809 in Boston. It was in Richmond that Poe grew up, married, and first gained a national literary reputation. Many of the places in Richmond associated with Poe have been lost, but several still remain. Family Father: David Poe, an actor Mother: Elizabeth Poe, an actress Foster parents: John Allan, Tobacco merchant and his wife, Frances Allan, cared for Poe while he was young, but never legally adopted him. Wife: Poe married his cousin Virginia Clemm Occupations †¢ Soldier †¢ Editor and literary critic †¢ Author Chronology Edgar Poe is the second of the three children of David Poe and Elizabeth (Arnold) Poe, both of whom were professional actors and members of a touring theatrical company. Mr. Placide’s Theatre Company in Boston employed Poe’s natural parents, David and Elizabeth Arnold Poe. They had been married in Richmond while on tour in 1806. Edgar Allan Poe was born January 19, 1809 in Boston, Massachusetts, but he considered Richmond his home, and called himself "a Virginian," where his mother had been employed as an actress. David Poe, unknown due to his more famous wife, his own promising career ruined by alcoholism, Edgar’s father, deserted the family when Edgar was still an infant; nothing conclusive is known of his life thereafter. While appearing professionally in Richmond, Virginia, Poe's mother became ill and died on December 8, 1811, in Richmond at the age of twenty-four. Poe's mother, Elizabeth, was buried in the churchyard of St. John's Episcopal Church where her memorial stone may be seen. St. John's is the oldest church in Richmond and is famous as the site of Patrick Henry's rousing "liberty or death" oration shortly before the Revolutionary War. The Richmond Theatre where Edgar Poe's mother had performed burned to the ground on December 26, 1811, only eighteen days after her death. The fire took the lives of many Richmonders including the Governor of Virginia, George Smith and his wife. At the site of the tragedy on East Broad Street, Monumental Episcopal Church was erected as a memorial to the victims. Her three children, who would maintain contact with one another throughout their lives, were sent to live with different foster families. Richmond families took in the other two children who were Rosalie, only eleven months old, by William and Jane Scott Mackenzie.

Digital Fortress Chapter 8

The twin-engine Learjet 60 touched down on the scorching runway. Outside the window, the barren landscape of Spain's lower extremadura blurred and then slowed to a crawl. â€Å"Mr. Becker?† a voice crackled. â€Å"We're here.† Becker stood and stretched. After unlatching the overhead compartment, he remembered he had no luggage. There had been no time to pack. It didn't matter-he'd been promised the trip would be brief, in and out. As the engines wound down, the plane eased out of the sun and into a deserted hangar opposite the main terminal. A moment later the pilot appeared and popped the hatch. Becker tossed back the last of his cranberry juice, put the glass on the wet bar, and scooped up his suit coat. The pilot pulled a thick manila envelope from his flight suit. â€Å"I was instructed to give you this.† He handed it to Becker. On the front, scrawled in blue pen, were the words: KEEP THE CHANGE. Becker thumbed through the thick stack of reddish bills. â€Å"What the†¦?† â€Å"Local currency,† the pilot offered flatly. â€Å"I know what it is,† Becker stammered. â€Å"But it's†¦ it's too much. All I need is taxi fare.† Becker did the conversion in his head. â€Å"What's in here is worth thousands of dollars!† â€Å"I have my orders, sir.† The pilot turned and hoisted himself back into the cabin. The door slid shut behind him. Becker stared up at the plane and then down at the money in his hand. After standing a moment in the empty hangar, he put the envelope in his breast pocket, shouldered his suit coat, and headed out across the runway. It was a strange beginning. Becker pushed it from his mind. With a little luck he'd be back in time to salvage some of his Stone Manor trip with Susan. In and out, he told himself. In and out. There was no way he could have known.

This genre has formed into a subculture because of its enormous following, lifestyle, and roots. The electro house music lifestyle grabs hold of mostly youth. However race, gender, and socioeconomic status is all ranges. A younger crowd is drawn to this genre because of the fun party scene involved and the care free attitude the genre evokes. The electro house genre became more than just music in the 2000’s. Popular DJ’s became the main draw for clubs. Typically this kind of party is called a rave. A rave describes the atmosphere which is dark, has strobe lights and sometimes accompanied by a projection of images to go along with the music. Ravers are the people who go to raves. This is the person who evokes the house music lifestyle. Typically a raver is young, dresses fashionably, and sometimes likes the drugs ecstasy, cocaine, and or MDMA. Raves can be known for their drug consumption but not all ravers are like this. An experienced raver usually brings or wears something that glows. If a raver brings glow sticks this allows an opportunity to dance with one in each hand, this is very popular while listening to electro house music. The fast paced music allows the ravers to dance rhythmically and can be compared to tribal like movements. In every day slang electro house is called electro. Jargon is also used to describe different kinds of electro house music. A bootleg is a remix made by a DJ who doesn’t have the official legal rights or permission to make the remix. These kinds of remixes are common and are done by every DJ. Mashups are similar and involve a producer taking elements from different tracks and putting them together to make a new one. White labels are twelve inch vinyls released for test pressing containing the bootleg tracks or remixes. Ravers also have a slew of jargon when talking about ecstasy. Mostly the terms E, X, or rolls are used and when on the drug most refer to it as â€Å"rollin†. To understand the subculture of electro house the history of house music needs to be established. House music in its first form was disco. The history of house music starts back in 1977 when â€Å"Saturday Night Fever† came out. â€Å"Saturday Night Fever† was an instant hit and a surge of young americans went to disco clubs. Disco at this time was a blend of 70’s funk, soul music, and rock. Most of the disco scene was in New York until 1979 when it spread to underground warehouses in Chicago and Detroit. The creation of house music was an attempt to get listeners hooked. So Chicago and Detroit DJs decided to introduce new techniques in the way disco was being presented. This combined with its separation from New York disco helped it evolve into its own genre. House music became known as more edgier, raw, and incorporated more diverse sounds. Electric keyboards, beat boxers, as well as beat machines helped to refine it into what it is today. Ohio, Indiana, Illinois, Missouri, and Iowa still have one of the largest house scenes to this day. Plenty of sub-genres of house music has formed since the 1970’s. There is acid house music, latin house, disco house, hard house, funky house, chicago house, NRG house, tech house, New York house, and the largest electro house. Electro house grew from house music and has shown its superiority since 2000. Electro house music differentiates from house music with its four to the floor beats, analogue basslines, high pitched leads, usually accompanied by a piano or string riff. The electro house tempo ranges from 120-130 bpm. The word electro comes from the 1980’s electro movement by which it was influenced. After the 1980’s synth pop sound came the electroclash movement of the early 2000’s. This is where electro house was born, particularly from the Detroit techno scene. The electro house genre has become steadily more popular on the Billboard Top 100. The mainstream electro house songs usually feature a remix of a slower original song like Kid Cudi, â€Å"Pursuit of Happiness† later remixed by Steve Aoki to become an electro house anthem. Other notable electro house DJ’s are Benny Benassi, Daft Punk, Crookers, David Guetta, Deadmau5, Justice, Klaas, MSTRKRFT, Spencer & Hill, and The Bloody Beatroots. Electro house music’s popularity has been on the rise since 2000. You tube has allowed this genre to spread because unknown DJ’s know have an effective platform to showcase their talents. Electro house ravers have a belief system similar to the disco era. Both groups of young adults want to escape their problems and live in the present. Their intertwining beliefs stem from house evolving from disco. Electro house makes it their own by taking it to a level of embracing who you are. An electro house raver isn’t easy to define because they embrace who they want to be. When you walk into a rave you will see some people dressed in halloween type costumes such as angel wings and bright neons or others in regular street clothing. You don’t have to wear a particular type of outfit to fit in. Electro house lovers value this because it’s about the music. The drug ecstasy is widely embraced for this reason. It always the raver to unwind and leave behind their troubles. Disco in the 70’s and electro house of today both allow an escape for their generation. This is also why electro house has such a wide range of youth followers. There’s no pressure to be rich or be a certain race. Where ever you are from and what ever you do electro house will embrace you.
