The Lone Ranger and Tonto Fistfight in Heaven Essay

The Lone Ranger and Tonto Fistfight in Heaven - Essay Example However Sherman Alexie doesn’t get satirical at all. He in his simple tones and simple style puts across the reader as what happened in the lives of his people. His metaphors although strong don’t overwhelm the reader. These metaphors come from his background, the culture he has been brought up in and the traditions and stories passed on from one generation to another. The thesis for analysis for this essay is the style of Sherman Alexie’s writing style which is literal and metaphorical, human and natural with a mix of reality and fantasy. The powerful use of metaphors and subtle hint towards magical realism gives a very special effect to the art of Sherman Alexie’s story telling. From the perspective of literature, they present many stories under one title. Some stories are kept in the background but their effects are seen on the characters and stories on the foreground, while some stories may go hand in hand in one story presented. Although the reader is reading many stories in one story, the main thread is not lost, which is what makes Sherman Alexie’s writing style unique and captivating. ... The party that is going on in the house is a vain attempt to fill the house with colours and laughter. In the same story Victor also states about the abject poverty during the festival time and his father being penniless to buy gifts for the family and the friends. The scene when Victor sees his father pulling out his wallet continuously, examining it as if there is miraculously going to be some money inside and keeping it back in the pocket touches every reader. It gives a very powerful picture in a very simple language. During other hurricanes broadcast on the news, Victor had seen crazy people tie themselves to trees on the beach. Those people wanted to feel the force of the hurricane first hand, wanted it to be like an amusement ride, but the thin ropes were broken and the people were broken. Sometimes the trees themselves were pulled from the ground and both the trees and the people tied to the trees were carried away. (Every Little Hurricane) Victor sees people hanging on, thin king that the hurricane will pass. He also talks about the people who were not party to the war, maybe by their own will or by situation, but they were affected alike by the war. He talks about people who tie themselves to trees to watch the hurricane, to feel it. Not all people participating in the action had a high end motive like sacrifice for the people and all, but they did participate in what was going on. Pulling out of trees indicates that whatever we stick to as a solid ground or possibly fundamental also gets shaken from the roots. The events and occurrences around you are so strong that they uproot you and change your direction altogether. One big hurricane in the story gives way to other little

What event of the 20th century has had the greatest impact on the Essay

What event of the 20th century has had the greatest impact on the world in which we live today Justify your answer and describe the relationship between the ev - Essay Example The Second World War, which raged between1939-1945, although primarily a war between European nations had a ripple effect, and soon countries as far flung as America, Japan, China were actively involved in the war. This war strengthened the notion that wars are conflicts fought between societies, populations and ideologies and not just battles for annexation. This war also had far-reaching impact on the economies of the world and led to the creation of new economic policies which brought about greater affluence as well as advances in science and technology. The world, after 1945, or rather, after the end of the Second World War, had a distinctly different look. Apart from the damage to humans, their habitats and industry, the war led to a re-alignment in the political and social sphere. The division of the world into pro-U.S. and pro-Russia camps emerged and capitalism and socialism began to define economic systems. Up until the Second World War, Germany had dominated Europe and Europe the world, but now the era of European supremacy was over. The age of global supremacy had begun. Europe, which was economically, politically and socially shattered by the war, lay in debris, but from this debris sprung new nations, because the bankrupt European nations could not control their colonies, spread all over the globe. The process of decolonization had begun, and the end of the war saw numerous new nations being added to the world map. One of the most important of these, in terms of impact, was the nation of Israel. It was born out of the idea that Jews needed a place which they could call their own, and since Judaism as a religion, had roots in Palestine, a portion of this Arab populated and Arab speaking land was handed over to the Jews. A resolution passed by the newly formed United Nations Organization partitioned Palestine into separate Jew and Arab states. While the Jews were overjoyed, the Arabs resented this snatching away of their

Experiment to Study Conservation of Energy

Experiment to Study Conservation of Energy Conservation of Energy Osamah Nuwisser Abstract: The purpose of this experiment was to study the conservation of energy. We considered all type of energies present in our system (KE and PE) to compute total energy at any instant during the experiment. We accomplish two tasks: first we verified the conservation of total energy during single step of the movement of the glider over the ramp and then we compared total energy of several consecutive up and down motions to check whether the collision of glider with the bumper at the lower end of the ramp was elastic or inelastic. For first task, we found that kinetic energy increases as potential energy decreases during downward motion of the glider but the total energy remains almost constant. For the second task, we found that the total energy of each step was less than that of the preceding one. This tells us that the collision between the glider and the bumper was inelastic due to which we have a net energy loss. We also increased height and mass of the glider and found that as a cons equence the coefficient of restitution decreases. Arbitrariness of PE is also described. Introduction: According to the law of energy conservation: Energy can neither be created nor destroyed; however it can be converted from one form of energy to the other. Also, we know that energy is conserved in elastic collision. Obviously, a loss in energy during a collision will imply that the collision was inelastic. In this experiment, we accomplished two tasks in which were able to verify/use the two mentioned facts. For the first task, we simply observed that during the first downward motion of the glider the total energy remained constant throughout the motion. Also, in our system there are only two types of energy involved: kinetic energy and potential energy. Thus Therefore, for the total energy to remain constant it is necessary that the kinetic energy increases as the potential energy decreases due to downward motion of the glider. This can easily be observed if we plot the three curves, total energy, kinetic energy and potential energy, in one graph for downward motion of the glider. For the second task, we recorded the same data for a few consecutive upward and downward motions of the glider. By comparing the amount of total energy for each step, we can tell whether the collision between the glider and the bumper was elastic or inelastic. If the total energy of each step is less than that of its preceding step, the collision is inelastic. Coefficient of Restitution:- For our case, it is defined as Its value can be in [0, 1]. In case of 0 the glider will be at rest after collision, in case of 1 the collision will be elastic. For intermediate values, collision will be inelastic with glider in motion after the collision. Experimental Description: The apparatus consisted of a glider which was moved on a tilted ramp with a bumper at the lower end. This set up was connected to the computer where the appropriate software recorded the required quantities. The glider was kept at the top of ramp at rest. Then it was allowed to move under gravity. It moved until it reached near the ground level where it hit the bumper and was reversed to move up the ramp where it stopped at certain height and then moved down again and so on. We stoped the data storage in the computer after about 10s. We repeated the experiment two time varying height and then mass. We took 3 readings in each case. Figure i: An Experimental Set -up Data and Analysis: Run 24: 2014-10-30 17:08:53 Figure ii: Position, Velocity Energy vs Time Data of position, velocity and energy (total, kinetic and potential) was plotted in the computer by the software against time (see figure ii above). PE was defined to be zero on ground level. For first task, we need to examine the variation of energy during first 2.5s. In start, PE is the maximum and KE is zero. As the glider moves down on the ramp, PE decreases and KE increases gradually. But we see that PE is not zero at its minimum. This non-zero minimum value is the value of the PE at the small height when it collides with the bumper. Figure iii: A Comparison of KE, PE ME We also find that the total energy is not conserved at the point of collision where we see a loss in total energy (annihilation of energy). For second task, we compare the values of the total mechanical energy for each cycle with that of the preceding one. It is evident from the graph of energy that this energy decreased suddenly after each collision. Thus the collision was inelastic. Also, we can see from the previous graphs that total energy of the glider was zero at certain instant after collision; the glider collided with the bumper, imparted its all (kinetic) energy to the bumper and came to the rest. Then bumper shifted a fraction of this energy to the glider in form of KE forcing it to move in the opposite direction (up the ramp). To read total energy as zero at certain point, we can construct the following simplest case. Consider the glider to be at rest at a height from the ground on the ramp (say 80cm). Obviously, KE is zero. We define the origin at this point. So its height w.r.t. origin becomes zero. Now we measure PE with reference to the same point (because of arbitrariness of PE) which becomes . Thus the total energy at this point is zero. As far as the conservation of energy is concerned, that is satisfied because we have defined origin at the highest point. As the glider moves down the ramp, value of h becomes negative. This negative value of PE annihilates the positive value of KE that is produced due to increasing velocity. Thus the total energy remains zero. Another way of doing the same is to define PE to be zero at the highest point, measure height as positive and add a minus sign with the formula for the PE in the equation of the total energy. To study the variation in the coefficient of restitution, we chose two continuous parameters: height and mass of the glider. We took 3 readings because the tendency of increasing/decreasing should not be study by taking the minimum possible, 2, readings due of the possibility of error. The data is given in the following table. Table 1 The following plot shows coefficient of restitution vs height. Figure iv: Coefficient of Restitution vs Height Second and third readings show that the coefficient of restitution decreases with increasing the height. But the first two readings tell the reverse. However, by considering the error bars of first two points we can conclude that: â€Å"Coefficient of restitution decreases with increasing height.† The following plot shows coefficient of restitution-mass vs mass. Figure v: Coefficient of Restitution Mass vs Mass This tells us clearly that: â€Å"Coefficient of restitution decreases with increasing mass.† Results and Conclusion: For task 1: we have found that total energy remains constant during the motion of the glider until the collision occurs. Thus law of conservation is verified and its limitation (inelastic collision) is found. For task 2: By comparing the total energy before collision with the total energy after collision, we conclude that the collision is inelastic. Also, we showed that by using the arbitrariness of the value of PE we can set the total energy of a sliding object to be zero. By varying two continuous parameters mass of the glider and initial height of the glider, we found that increasing any one of them leads to a decrease in the value of coefficient of restitution. Since smaller value of coefficient of restitution means greater loss of energy, we conclude that: by increasing height or by increasing mass, more energy is lost during the collision. The physical reasoning behind this conclusion can be understood. In both the cases, increasing height or increasing mass, the maximum PE (mgh) increases. This entire maximum PE becomes maximum KE just before the collision. Thus more energy is lost during the collision. References: Air Track and Cart (1996).

Heredity and Hormones Effect on Behavior Essay -- essays research pape

Human behavior has been a mystery to scientists and psychologists for years. What causes humans to act the way they do? Is it learned by experience, or inherited from prior generations? The human brain is a complex machine driven by numerous intangibles that influence our thinking process directly and indirectly. The endocrine system in the human body stores a chemical known as hormones. Hormones are released by endocrine glands into the bloodstream and travel throughout the body carrying messages. A hormonal impulse is similar to a nerve impulse only much slower. The messages carried by the hormones trigger different behaviors. Hormones can affect behavior in many ways such as: Mental activity or tiredness, boredom or excitement, sexual behavior, the ability to maintain focus, boldness, the potency of stress, and the admiration of friendship. Hormones can also be a leading factor in whether a person is in a good mood or a bad mood (Morris & Maisto, 2005). Endocrine glands located in different parts of the body all release unique hormones, some of these hormones can affect behavior in different ways. The thyroid gland, located beneath the voice box releases the hormone known as thyroxin. Thyroxin is the hormone responsible for regulating the level of metabolism in a human body. Therefore, thyroxin can be related to the amount of energy one has, their sleeping habits, ability to focus and concentrate, and even their individual temperament. The pituitary gland, located on the bottom side of the brain, produces a variety of hormones, some of which affect human behavior. These hormones can have an affect on sexual conduct and desire (Morris & Maisto, 2005). The gonads in the human body differ depending on the sex of the human. T... ...utionary psychologists believe that behavior is not influenced by environments or situations but by natural instincts that have been inherited through a process known as natural selection. Natural selection suggests that only those who posses survival traits and adapt well to their surroundings survive and pass on these traits to offspring (Morris & Maisto, 2005). Human behavior remains a great mystery to psychologists and there is really no evidence that pinpoints the exact cause of our behavior. Some things are certain, genes and hormones directly affect behavior, but the extent of this influence is still debatable. There are many intangibles that are factored in when considering human behavior but no single factor shows evidence of how our minds make decisions. Human behavior is directly influenced by decisions, and decisions are apparently not an exact science.

A fish in a pond

A fish in a pond is a prime example of an organism living in an ecosystem.   There are multiple biological and non-biological interactions occurring in a pond.The fish may interact with its own fish variety, with other fish species, with other vertebrates, non-vertebrates, plants and microorganisms.   In addition, the fish may also interact with its environment—the water, the fish bottom, the rocks and sand.   The fish’s well-being is affected by the amount of dissolved oxygen, the water temperature, salinity and amount of sunlight.Any imbalance or perturbation may affect the health of the fish.   The fish’s ecosystem is very similar to an individual who belongs to an organization.   That individual intermingles with other members of the group, at the same time interacts with the immediate environment of the organization, be it an office cubicle, the entire workplace or the whole building complex.The member’s state of well-being is also influence d by the conditions of the place, such as the temperature, lighting, humidity, office furniture/amenities and space allotments.   Poor ventilation and substandard lighting in the workplace may affect the efficiency of the member of the organization.There are both advantages and disadvantages in being a big fish in a little pond and a little fish in a big pond.   It is good to be a big fish in a little pond because the big fish will have a greater opportunity to survive in the little pond because it can eat the little fishes in the pond, as well as ingest most of the good seaweed in the area.   For a top-rank authority member of a small organization, this individual will receive most of the recognition given for the achievements the organization has made.That member will also receive a higher salary than the rest of the regular members of the organization because he is known to have the best qualities and capabilities in the organization.   Just like a big fish in a little po nd that has his own space or territory, the top-rank member of the organization has a spacious office in the building with matching fine quality furniture and other amenities in his office space.   Unfortunately, the big fish in the little is also the first fish that is usually caught by fishermen because its big size makes it very visible for capture.The same thing happens with the top-rank member of an organization, he is the first person to be blamed once a problem or financial crisis arises in the organization.   The top-rank member is an easy sight because he represents the organization in almost every event or interaction with the rest of the business world.

How to write a methodology (2018) Dissertation Help

How to write a methodologyDissertation Help To address how to write a methodology, in the Methodology section of your dissertation you have to justify and explain your choice of methodologies employed in your research. You don’t however have to explain the methodological approaches that you could have used. In other words, say why you chose the ones you did and don’t say why you didn’t choose the others that were at your disposal.How to write a methodology?You may consider whether or not someone else could easily replicate your study based on what you have included in this section and in the appendices. In this section you have to explain very clearly how you arrived at your findings and state clearly why they are reliable and how they answer your research questions or test the hypotheses on which your research was based.How to Structure the Methodology Chapter?Section I PhilosophyThis will deal with the philosophy which underpins your research. You will set out the research paradigm here. While there are many different research philosophies you can adopt, three of the most popular are positivism, post-positivism and interpretivism. Each is suitable for a different sort of study, and each involves different assumptions about the world (ontology), how we know that world (epistemology) and the nature of knowledge. You may also be interested in: What is dissertation and why is it important? The following table sums up key details about each philosophy, and should help you decide which is most useful for your area of study. PHILOSOPHYBRIEF DESCRIPTIONTYPE OF DATA/DATA COLLECTIONONTOLOGYEPISTEMOLOGY PositivismAims to mirror scientific method. Uses deductive reasoning, empirical evidence and hypothesis testingQuantitative data, surveys based on scientific methods, larger sample sets, numericThe world is objective and independent of our subjective experienceThe world is knowable, and this knowledge is communicable between agents InterpretivismAn approach to studying people, particularly in social sciences, that starts from position that the subject matter is inherently different from non-human subjects.Qualitative data, subjective experience, small numbers of respondents, detailed examinations, textualThe world is dependent on the many subjective experiences of that world, and does not exist independently of experienceThere is no possibility of ‘objective’ knowledge of the world, all we have are different experiences. Post-PositivismShares the main assumptions of positivism, but takes a more relativistic perspectiveQuantitative, qualitative, mixed methodsThere is an objective world, but knowledge of it is filtered through the subjective experience of individuals. Knowledge is by its nature partial and bound by individual experienceSection II: ApproachHow to write a methodology Research Onion, Source: Saunders et al (2012) Here you will need to explain the context of your research, its limitations and specifically answer the â€Å"w-† questions, which include How, Why, What Where and WhenThe main decision you are likely to make is whether you will be using qualitative or quantitative methods (or methods which combine both). Each method is associated with a different approach to gathering data. In general (there’s lots more material available online if you want to learn more) you first need to decide whether you are going to work along broadly positivist, scientific lines, starting with a defined hypothesis and testing this against reality. If so, you are likely to be collecting numerical data in reasonably large quantities (30 or more) and running statistical tests on this data. In other words, you’ll be using a quantitative approach (to do with collecting and manipulating data).On the other hand, you might be more interested in exploring broad areas, probably to do with people’s experiences of, perceptions of or emotional reactions to a subject, and looking in detail at these responses in all their richness. By looking at broad areas of interest, you are aiming to generate theories about the area you are investigating. If this is the case, you will be adopting a qualitative approach (concerned with analysing textual responses in detail).Finally, you might want to use a mixture of both methods, and indeed ‘mixed methods’ research is becoming increasingly popular. It’s particularly useful when you want to reflect different perspectives on a subject, or put quantitative information into a robust real-world context. Other Relevant Articles: 1. Should I use Primary or Secondary Research? 2. The Steps involved in writing a Dissertation.Section III: Strategy and Research DesignIn this section you will outline how you collected your data; and you will have to explain your choice for using the methods you did, such as online surveys, phone surveys, face-to-face-interviews and so on. How did you choose your sampleExplain the choice of age group and ethnicity of your respondents. What questions did you ask and how have these contributed towards answering your research question or how did these test your hypothesis which formed the basis of your researchIt is actually better to write this at the start of your research, so that it can be changed if your methods are not producing the results you need. However as this is not usually how dissertations are written- they are written in hindsight, then you will have to be honest about the flaws in the design. When writing or planning this section, it’s good practice to refer back to your research questions, aims and objectives, and ask yourself whether what you are planning to do is the best way to answer the questions and achieve the objectives. It’s best to do this at an early stage, rather than look at the data you collected and find it doesn’t throw any light on the topics you wanted to ask about. Another thing to remember is that you need to convince the reader that the results you obtain are valid and reliable. When discussing why you selected the methods you did, you should be convincing that these methods are the best ones available given what you want to achieve.Section IV: Data Collection and Analysis MethodsYou will have to explain how the data was collected (by what means) and then explain the analysis tools you used. For example, if you were sampling texts, or have a lot of qualitative data are you using semiotics analysis, discourse analysis and so on. If you used software tools then you will have to say what these were and why you chose to use these particular ones. In this section you have to explain very clearly how you arrived at your findings and state clearly why they are reliable and how they answer your research questions or test the hypotheses on which your research was based. . The choices you made at the beginning of your research study should have been aided by contributions from your supervisor. That being so, writing the Methodology section will be the easiest part of your dissertation.Section V: Ethics, Reliability, Validity, Generalizability and LimitationsFinally, your methodology should discuss the following: Ethics – you need to explain how you have taken into account the ethics of your research, particularly if it includes human subjects. What steps did you take to make sure no one involved is harmed in any way (even very minor ways) This discussion should include how you dealt with issues of confidentiality of data, and data protection Reliability – that is, the extent to which your study is reliable, in that the results can be repeated by other researchers at other times. To be informative, studies should be both reliable and valid Validity – that is, does the study test what it sets out to testAre the measures you use able to accurately assess what you want to look at Generalizability – to what extent are the particular results you obtained true of other populationsNot all studies are as generalizable as others, but you need to discuss how generalizable your results are likely to be, and why. Limitations – finally, you need to acknowledge any ways i n which the study was limited. Was it restricted to only one country, when data from other regions would be usefulOr were only people of a certain age interviewed, when a more representative cross-section of the population would have yielded more informative results Continue Reading: 1.
