Multiple Linear Regression - Assignment Example del is linear in the sense that every predictor variable is either a constant or the product of a parameter (ÃŽ ²Ã¢â‚¬â„¢s) and a predictor variable (x’s). The researchers further investigated whether the multiple linear regression models provided a better description of the relationship between the wave modes than would a linear regression model with only a linear predictor. In the model, y (the response) is the ISOw (westward moving intraseasonal modes) and x (the predictor variable) is the ISOe (eastward moving intraseasonal modes). ISOe is further broken down to into more variables by applying power functions of the predictor variable to create a polynomial. Higher power terms are included in the model in order to seek evidence of any improvements in how they increase the accuracy of how wave modes are displayed. This selection is arbitrary and purely based on the assumption that it may lead to the development of a better model for depicting the relationship between the independent and dependent variables. Each of the introduced independent variables is then evaluated for significance (at the 5% level of significance) in order to establish its relevance to the entire model. Each item with a coefficient whose p-value falls below the 0.05 (5%) threshold is considered as being statistically significant. Such variables are retained in the model. The test of significance was repeated several times using the bootstrapping technique. A^sub s, T^ = (X^sup T^^sub t^X^sub t^)^sup -1^X^sup T^^sub t^Y^sub s,t+T^ by solving for a specified lag for the regression coefficients. In this equation, â€Å"T† is the matrix transpose, â€Å"a† the coefficients, and s the grid points (more easily interpreted as the lags). The regression equation involving the nonlinear terms is then tested for suitability against the ordinary linear regression. The model that appears to explain more variance in the response is deemed better.

Literary Analysis of the poem Beowulf Essay Example for Free

Literary Analysis of the poem Beowulf Essay Beowulf is considered as one of the longest poems in literature with more than 3,000 lines. It is has no known author, but it was considered as the national epic of England. Beowulf is a man a hero who faced three major battles in the poem. These battles were not against other humans, but were against monstrous creatures (The Norton Anthology of English Literature). It is a poem that deals with legends, of hero and his men, and his great battles. It is composed mainly to entertain, a work of fiction with several relations to historical context. And with this, some speculations were raised, saying that Beowulf was something more that a poetic narrative of the hero, Beowulf. The epic poem was then related to a Christian context, saying that it was a Christian allegory. The poem takes place in the late 5th to 6th century, following the Anglo-Saxon’s settlement in England, after making contact with Germanic tribes in Scandinavia and Germany. Beowulf may be based on real people and real events at that time in Scandinavia. The clans mentioned in the poem were clans which are found in the area, as well as some of the prominent personalities in the story. So basically, the epic poem is a work of fiction but was based on factual characters and events during that time. The time of Beowulf was a time of Paganism, but Beowulf himself addresses a higher being rather than man, wherein he presents himself to the Father Almighty. According to Helterman, â€Å"As the view of the intellectual setting has shifted from a pagan to a Christian context, this ‘something more’ has been seen as a Christian allegory or didacticism†¦yet the tone of the poem and the lack of specific Christian allusions cause difficulties for such an approach (Helterman). The poem didn’t mention anything regarding Christianity, and Beowulf was a pagan. But there were several â€Å"Christian sentiments of a general sort† which were attributed to the hero. Because of the Christian-like characterization of the hero Beowulf, there were several speculations saying that the author was a Christian in England who wrote about Scandinavian history, which then became the epic poem Beowulf. But some said that the Christian attribution in the hero’s character could mean that he was an archetype, the generic, idealized model of a person (Chickering). And at that time, Christianity was a budding religion, wherein Beowulf’s character could have been patterned into that of an ideal Christian. Beowulf as the hero of the epic was made the way he is, the ideal person. But then again, every hero has its counterparts. And just like Beowulf, his counterpart can be seen in a Christian context. The epic poem Beowulf is divided into three major battles. The first one is his battle with the monstrous creature called Grendel, which was the reason why he went to Hrotgar. Just like Beowulf, Grendel also has a Christian context. He is to be the descendant of Cain, the son of Adam and Eve which was banished for killing his own brother. Because of this, Grendel is given an antagonistic comparison with Cain, who was the first person to commit murder in the Christian bible. Grendel, along with his mother, was compared to as the kinsmen of Cain, whereas Beowulf was the pagan hero considered as the archetype of a human being. Beowulf and Grendel were great opposites, as manifestation of the forces of good battling with the forces of evil, or in the context of religion and Christianity, will be righting the wrong. Beowulf’s character is the manifestation of Christianity’s good; wherein his defense of Heorot was an act to â€Å"order the chaotic universe,† where Grendel and his mother on the other hand, were the forces that bring chaos, falling into pattern of disorder (Batchelor). This is manifested by their physical appearance wherein they do not resemble or have any human characteristics. They were monstrous in size and strength. They can kill people with the swipe of their hands, and they even eat people, as to what Grendel did to Hrotgar’s men. Another possible association with religion and Christianity was during the creation of Heorot, the great hall which was built for the people of King Hrotgar (Helterman). The creation of the hall was because of the word of the king. It is the same as that of the Christian’s Genesis, wherein with the word of God, there was light. And it was with that word that He was able to create day and night, and everything that he wished and commanded. Just as with Hrotgar’s word, Heorot was created, all for the sake of the people, since in this hall they dined, ate and sang, until the time that Grendel came into the story. When Grendel came, it was like introducing chaos into order so that you could cleanse it, just like the cleansing of the sins of the people, just like the Great flood, where chaos or the flood was added in order to cleanse the world of the sinners. When Grendel came into Heorot, chaos caused destruction, thus it would require reconstruction, where after reconstruction was the cleansed state. Grendel, even though he caused a great deal of devastation to the people, has served a purpose, which was to strengthen the then destroyed Heorot. His chaos has led to a good outcome in the story. It could also be viewed on another angle, where the battle between Beowulf and Grendel was actually the same as to that of the myth of creation, where light and darkness mixed and â€Å"fought† in order to create the earth and everything in it. Another instance that relates the epic poem Beowulf to Christianity was during the battle against the mother of Grendel. Beowulf was definite on the losing end at that moment, since his sword, Hrunting, lost its powers and cannot harm the creature he is up against with. In his desperation, he was able to locate a sword in the Grendel’s lair, which only he could be able to use. It was a heavy sword of the giant, which he used to behead the mother of Grendel and eventually prolong his life. Even though he was able to slay the monster and keep his life, he gives the credit of his victory to the â€Å"higher being,† the â€Å"Wielder of Men. † It was an indirect association to God in Christianity, since he recognizes His powers and that his victory wasn’t possible without him. Beowulf being a pagan is just a characteristic, since there was no evidence of him knowing about Christianity (Batchelor). But the fact that he addresses to a higher being is a manifestation of being Christian even in his beliefs. The epic poem Beowulf is truly a literary piece that was made to entertain, with the life of Beowulf as a hero, his adventures, his battles, and even his death, makes it a wonderful read. But there are other underlying concerns that could come about while reading the epic. It is undeniable that there are other meanings in what was written, rather than just to entertain. The poem Beowulf is associated with religion, especially Christianity. The main character’s recognition of a higher being is but one of many manifestations of this underlying messages.

Post Enlightenment European Culture: Metropolis (1927)

Post Enlightenment European Culture: Metropolis (1927) Final Paper: Metropolis (a 1927 German film) 14210568 Many people are used to the image as a way to receive information, through the film is the story. Film is not just the life of entertainment, as a media form, is presented in conjunction with a lot of culture produced by an art type images. The film â€Å"Metropolis† is a significant German silent science-fiction film released in 1927 by Fritz Lang. It able to represent and portray the culture, political and social ideologies in Germany during that time. Since the remarkable work of â€Å"Metropolis†, it is regarded as one of timeless classics that withstand the test of time. The film â€Å"Metropolis† explicitly demonstrated different aspects of European culture since the Enlightenment, including the working class culture, totalitarian culture and the worship of technology. First of all, the relation between the working class and the bourgeoisie is revealed. In the film, the city was vertically separated into two spaces clearly, implying the differences of lifestyle between the working class and the capitalists, by sharply contrast of spatial distribution and configuration. The film opens by showing the city of the workers which is below the ground. Workers who wearing monotonous uniforms have to work day and night as a machine in the factories where are completely dark. Conversely, there is an entirely subversive life on the ground. It is the world of the bourgeoisie which is a thriving metropolis. It is a magnificent, gigantic city with gleaming skyscrapers linked by aerial highways, suspension bridges, and bustling street. People live in comfort and plenty, with huge stadiums and pleasure gardens. These effusive and energetic images show the life of the bourgeoisie are full of technology and possibilities. Also, the presence of the sentence â€Å"As deep as lay the workers’ city below the earth, so high above it towered the complex named the ‘Club of the Sons,’ with its lecture halls† in the film also revealed the mirroring yet opposite environments in which the labor and the capitalists live in. Such high distinction emphasizes the social relationship of bourgeoisie and proletarians, and the rulers and the exploited. Working people are seen as a labor force, and usually regarded as passive victims of laissez faire as well as the capitalism (Thompson, p.3). For the purpose of working for the chosen elite Joh Federsen, the ruler of Metropolis, they are the masses of nameless workers who have to labor in an industrial complex to accomplish repetitive and dull tasks, and just served as a cog in a machine or a tool or production without emotional expression and communication, in order to sustain Metropolis. It seems that the film â€Å"Metropolis† portrays the working class culture which workers are always in alienation, and squeezed and exploited by the rulers, in particular their labor forces, by comparing the lives of workers to capitalists. Besides, the pictures drawn in the movie indicates that the workers has class-consciousness (Thompson, p.1). For instance, Freder is not accepted by the workers when he attempting to integrate into the working class since the workers recognize him as Joh Fredersen’s son. Apart from the working class culture, totalitarian cultures are also demonstrated in â€Å"Metropolis†. Totalitarian movement and government are characterized by aiming at total domination and resting on mass support (Arendt, p.351). Totalitarian regimes seek to hold the total authority over the society and dominate all aspects of public and private life wherever possible. In the film, Metropolis is ruled by wealthy industrialists (capitalists), led by Joh Fredersen, a king in a suit, also the commander-in-chief. Joh Fredersen is the â€Å"head† of the city, is to give commands to the machine systems (i.e. the workers), in order to keep the city runs. He is the leader of the â€Å"elites† who holding most of the resources and managing the working class. However, underground-dwelling workers have to toil constantly to operate the machines, and they have no choice. The workers were only the â€Å"hand† of the city, just like robots, â€Å"one command, one a ction†. They are not be respected and cared by the ruler; instead, they are just considered as the means of production. For example, when Freder told his father about the industrial accident that resulted in death of workers, Joh Fredersen first seen to be no response and tried to ignore him, and later he said the workers should belong to the depth where it was not they belonged to. It seems that no actions should be taken since Fredersen think those workers are just the tool operating the machine system. On the other hand, the workers did not have complaints and actions against the commander, even still continued to work as before as nothing was happened. It reveals that the working class is living worthless, and is dominated to work for serving the capitalists. Metropolis is obviously a totalitarian regime as the working class is managed by Fredersen, and they have been isolated and ignored. Furthermore, the worship of technology and science and its relation with the bourgeoisie are also reflected in the movie. â€Å"Capitalism is the first mode of production in world history to institutionalize self-sustaining economic growth.† (Habermas, p. 247) It leads to an extremely fast rate of economic growth, which can increase living conditions and lead to a more prosperous country, therefore, legitimacy of the state can also be provided. And technology and science is the dominating force in the capitalist society. Metropolis is obviously a kind of capitalist society. In the film, there are lots of tall skyscrapers touching one another with roadway fingers and buzzed about by airplanes and blimps, in particular the Tower of Babel, and thus it is technology-driven. In order to enhancing the economic growth, the leader of Metropolis as well as the capitalists will emphasize work as an important force; technology plays a major part of the society in sustaining the city. The refore, no longer is work part of the subsystem of the society, work becomes the driving force in the society. For example, when the grievances of the workers broken out, with strike, revolt and revolution, the Metropolis has to face the suffering from the attack of underground water. It seems that there will be the collapse of the society when the action of work, the dominating force in the capitalist society and is prompted by the bourgeoisie who are profit-seeking, is not functioning. The machine system used to sustain the city is fail as the strike of the workers. On the other hand, Fredersen also cannot build, control or monitor the city without technological power and the work-flow of information supported by technology.He has to depend on technology for his control of Metropolis. It seems that technology and science become the ideology of Metropolis, the capitalist society, to maintain the city operates. For the movie â€Å"Metropolis†, the scene showing the two clocks vertically strike me most. The bottom clock counts off the time in ten hour increments for the workers, while the upper clock uses a 24-hour system, for managers, engineers and administrators. I think these two clock is about the interpretation of time, reflecting the two social classes which is the working class and the capitalists, also implying work is the driven force of the society. This scene is fully illustrated the working class culture. The clock emphasizes the control of time over the workers. Just as a machine is always under the control of an external influence, the worker is controlled by the system of Metropolis. They just know they should work day by day, and denied the rhythms of daylight and night. Unlike the capitalists on the ground, their lives is work, no other things. For them, time is not important and even meaningless. The exploitation of the workers, and as the passive victims of capital ism are the significant characteristics of the working class culture. To conclude, different aspects of European culture since the Enlightenment are demonstrated by the film â€Å"Metropolis†. Not only that, the movie also represent and reveal the current working condition of labors in the certain extent. In some workplace, especially in the developing countries with cheap labors, workers are much easier in alienation, only working relationship and exploitation but no meaningful communication and mutual care between them and the capitalists. Same as the film portrayed, no one will leave their sphere. No one thinks about how the other half lives. No one is curious. The interaction becomes less important, and many of the social and cultural attributes of society fall apart. This is an unhealthy social phenomenon that should be aware and addressed.

(Black 1999) These examples of career changes reflect a common trend—increased job mobility. The linear career path that once kept people working in the same job, often for the same company, is not the standard career route for today's workers. Today, many workers are pursuing varied career paths that reflect sequential career changes. This set of ongoing changes in career plans, direction, and employers portrays the lifetime progression of work as a composite of experiences. This Digest explores how changing technologies and global competitiveness have led to redefinition of interests, abilities, and work options that influence career development. Influences on Career Mobility Job mobility no longer carries the stigma once associated with job change, although it can be emotionally stressful. Corporate upheavals of the early 1990s and low unemployment rates during the last part of the decade have caused changes in job search and hiring practices. Companies, especially those in technology fields that are in dire need of qualified, skilled, and experienced employees, are driven to recruit workers away from their current employers. Workers, who see job mobility as a way to find work that is appealing, challenging, and offers growth potential, are viewing career change as a way to progress through the uncertainties of the workplace.

Consumer Behavior Case Study Do Our Avatars Learn Essay

1) According to the text, classical conditioning occurs when a stimulus that elicits a response is paired with another stimulus that initially does not elicit a response on its own. As time passes, the second stimulus is able to cause a similar response because of the fact that we associate it with the first stimulus. An example of classical conditioning would be one that was demonstrated by Russian physiologist Ivan Pavlov. He conducted research on digestion in dogs. Pavlov was able to induce classically conditioned learning when he paired a neutral stimulus (a bell) with a stimulus that was known to cause a salivation response in dogs (he squirted dried meat powder into their mouths). The powder represented an unconditioned stimulus due to the fact that it was naturally capable of causing the response. As time passed, the bell represented a conditioned stimulus. Initially, the bell didn’t cause salivation. However, the dogs learned to associate it with the meat powder and began to salivate at the sound of the bell only. The drooling of these canine consumers because of a sound, now linked to feeding time, represented a conditioned response. Pavlov demonstrated a basic form of classical conditioning that primarily applies to the responses that the autonomic (e.g., salivation) and nervous (e.g., eye blink) systems control. Meaning, it focuses on visual and olfactory cues that induce hunger, thirst, and other basic drives. When marketers are able to consistently pair these cues with conditioned stimuli, such as brand names, consumers may learn to feel hungry or thirsty when they encounter these brand cues at a later point. This is an example of how classical conditioning can operate for a consumer who visits a new tutoring Web site and is greeted by the Web site’s avatar who resembles Albert Einstein. The individual might not pick of the olfactory cues the first time he visits the Web site, but over a period of time he/she will. 2) According to an online source, instrumental conditioning (also known as operant conditioning) is a form of learning in which an individual modifies the occurrence and form of its own behavior due to the consequences of the behavior. The difference between instrumental conditioning and classical conditioning is that instrumental conditioning deals with the modification of â€Å"voluntary behavior† or operant behavior. Operant behavior â€Å"operates† on the environment and is maintained by its consequences. On the other hand, classical conditioning deals with the conditioning of reflexive behaviors which are elicited by antecedent conditions. Behaviors that are conditioned via a classical conditioning procedure are not maintained by consequences. This is a learning process that we most closely associate with the psychologist B.F. Skinner. Skinner demonstrated the effects of instrumental conditioning by teaching pigeons and other animals to dance, play Ping-Pong, and perform other activities when he systematically rewarded them for desired behaviors. Due to the fact that responses in classical conditioning are involuntary and fairly simple, we make those in instrumental conditioning deliberately to obtain a goal, and these may be more complex. The desired behavior might be learned over a period of time as a shaping process rewards our intermediate actions. From all of this research about instrumental conditioning, we conclude that a consumer who purchases a new outfit for his avatar on a virtual world would be modifying the occurrence and form of the avatar’s behavior due to the consequences of the behavior. 3)I believe that consumers do build associative networks through their avatar’s experience just as they would with any other product or service. The text states that we each have organized systems of concepts that relate to brands, manufacturers, and stores stored in our memories. The contents, however, depend on our own unique experiences. We should think of these knowledge structures, or storage units, as complex spider webs filled with pieces of data. Any information that is incoming gets put into nodes that connect to one another. When separate pieces of information are viewed as similar, we chunk them together under some more abstract category. Then, we are able to interpret new, incoming information to be consistent with the structure we just created. This helps to explain why we are better able to remember brands or stores that we believe â€Å"go together.† Recent research has indicated that people can recall brands that are not as obviously linked. However, in these cases, marketers have to work harder to justify why the two things go together. I do believe that this network is part of the consumer’s overall associative network for that brand. This is because in the associative network, links form between nodes. For instance, the text states that a consumer might have a network for â€Å"perfumes.† Each node correlates to a concept related to the category. This can be an attribute, a specific brand, or a related product. When the consumer is asked to list perfumes, she only recalls those brands that show up in the appropriate category.

Main Themes in The Glass Menagerie Essays

Main Themes in The Glass Menagerie Essays Main Themes in The Glass Menagerie Paper Main Themes in The Glass Menagerie Paper choosing instead to believe that when te gentleman caller will fall for Laura when he sees how lovely and sweet and pretty she is. Meanwhile, Laura retreats to her glass menagerie, her beautiful yet fragile world of little glass animals. In this world, the special glass unicorn gets along nicely with the other normal horses, in contrast to Lauras social isolation due to her weirdness. Tom escapes to his world of movies and the bars to escape from his daily life of a nagging mother and a boring job at a shoe factory, and Jim, the supposed emissary from a world of reality, is too, trapped in the memories of his high school glory and the hopes for the American Dream of future opportunities, confidently declaring Knowledge Zzzzzp! Money Zzzzzzp! Power! Thats the cycle democracy is built on! Finally, the world outside the Wingfield apartment is no different. To get away from the hardships of the Great Depression and world conflict, the Americans indulge in hot swing music and liquor, dance halls, bars, and movies, and sex that hung in the gloom like a chandelier and flooded the world with brief, deceptive rainbows. Thus, in their exploitation of illusions to cope with reality, the Wingfields become a kind of microcosm for the entire country. The Glass Menagerie identifies the conquest of reality by illusion as a huge and growing aspect of the human condition in its time. The loneliness of human beings is a recurring theme in Williams works and is also clearly portrayed through the characters of The Glass Menagerie. Since being abandoned by her husband, all Amanda has left is her family. Despite having each other as family, each of them is alone in a sense. Amanda clearly loves her children, but she lacks understanding and is unable to communicate her feelings and thoughts to them, stating to Tom, theres so many things in my heart that I cant describe to you. As a result the family ties become strained and gradually the family falls apart, leaving her to be more alone than ever. Vice versa, Tom is also lonely because he is unable to make Amanda understand him, claiming to Amandas comment Thats true of me too. . Being a poet, he is trapped in his own world and is unable to communicate with even his family, let alone establish any worthwhile relationships with his co-workers. His loneliness increases when he discovers the world outside is no more understanding towards him than the world within his family. As for Laura, she has never been able to successfully communicate with anyone due to her introverted nature and inferiority complex, admitting I never had much luck at making friends; hence loneliness is more natural to her. Her thwarted chance at happiness with Jim as well as Toms abandonment gives her only deeper loneliness. In a way, Williams is trying to convey that humans are all essentially alone. Hence, the themes of individuals trapped under circumstances, the use of illusions to combat reality, as well as the inevitable loneliness of humans, are clearly presented in Tenesse Williams The Glass Menagerie. These themes are prevalent in the plight of the characters, palpable in their tragedies, individual worlds of illusions, and their loneliness due to inability to communicate with each other. Hence the combination of these results in a delicate and meaningful play, an expert yet sympathetic observation of human nature.
