It provides a clear modular structure for programs which makes it good for defining abstract data types where implementation details are hidden and the unit has a clearly efined interface. ? It makes it easy to maintain and modify existing code as new objects can be created with small differences from existing ones. ? It provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer. This is particularly useful for developing graphical user interfaces.

Dreams and Escapism within Death of a Salesman and Road Essay

Death of a Salesman was written in 1949 in New York, right on the brink of a consumerist explosion. The American Dream that people had spent his life in pursuit of was suddenly altered and became highly materialistic. This left people, such as the character of Willy Loman, questioning their life and feeling secluded from this new wave of materialistic dream and the abandonment of self sufficiency. Along with this, other plays such as Cartwright’s Road was written and set in eighties Britain, in a northern Lancashire town. This was a time of high unemployment, particularly in the North, under Thatcher’s conservative power. The working class were hit hard and many declined into poverty, any dreams at this point would appear hopeless faced with recession and a government that showed no remorse to the characters depicted in Road. Both were faced with times of dramatic change that both sets of characters could not adjust to cope with, which is where escapism is used. In the introduction of the play, Miller proves to his audience that dreaming is evident in Death of a Salesman. â€Å"An air of the dream clings to the place, a dream rising out of reality†. By using the phrase â€Å"rising out† this indicates that this dream is a way of escaping, this sets the scene and tone of the whole play and how Willy is in a constant dream, unable to acknowledge the reality of his existence. The structure of the play is constructed like a stream of consciousness throughout, adding to the overall theme. Parallel to this, the structure within road is fragmented to emphasise the state of life within Road and also to represent the broken relationships. The characters within Road make no effort to disguise the misery and reality apparent in their lives and portray it at face value through various monologues, which although are not structurally reality orientated the messages within them are. They are full of hopelessness and failed dreams and so for many; escapism is taking refuge in sex and alcohol to numb the despair and even starvation in an extreme case, as being a way out. However, some characters experience escapism through hallucination and Skin-Lad turned to religion to resolve his despair. Another form of escapism used is taking refuge in the past. Willy constantly encloses himself in past situation, re-living them and even having conversations with characters that are only apparent in his own mentality. The positioning of scenes such as these let the imagined characters break all boundaries by entering or leaving rooms through â€Å"walls†. This further represents the fragile psychological state of Willy and how his mind has no restrictions and is unable to differentiate reality from creations of his own mind. Willy constantly refers to the past as more desirable, the first time Willy is seen lapsing off into the past is when he encounters Biff after arriving home. The conversation between Willy and Linda reflects Willy’s disappointment in Biff and what he has become. After failing to deal adequately with his feelings, he escapes into a time when things were better for his family. The fact he is more engrossed with memories than the present day, shows his willingness to escape to the past; where his life was once idyllic, and his lack of compassion to stay in reality. This type of escapism can also be identified within Road, particularly in Jerry’s monologue where the opening line states â€Å"I can’t get over it. I can’t get over the past, how it was. I just can’t†. He goes on to further reveal to the audience about the time he spent in the RAF on national service. Similar to Willy, as he is reminiscing, his dream enters into reality. As he describes certain objects he reaches out to touch them as if they are still there. This device is used to create a link between past and present and dream and reality. It is obvious both characters use the past to cover the present reality. The language within Road, particularly within the monologues, does not provide a realistic representation of the characters typical vernacular which is usually gutter language. This is used to create a contrast against themselves and their lives, another way to separate themselves from their reality. The text adapts a poetic resonance which seems unfitting for the topics being covered. â€Å"I’ve been done by them, it, the crushing sky of ignorance† it has a strange beauty, just like road itself. Humour is also present throughout to divert away from what would be considered tragic occurrences however this is occasionally interrupted by graphic realism, such as Claire and Joey’s untimely death through starvation. But true to the structure of the play, it is quickly overlooked by the narrator, Scullery who simply states â€Å"Hey, we’s gonna miss last orders† which would not be considered a realistic reaction. However, within Death of a Salesman the language which is used is typical of the characters. It is the context in which it is presented that provides the difference, particularly Willy’s conversations with characters which are not present. The end of Road depicts a group of characters chanting together â€Å"Somehow a somehow a somehow – Might escape†. This is an unrealistic technique used to restore the hope and dreams that had been diminished throughout the entirety of the play. It also re-assures the audience that there might be someway out of this squalid existence that has been portrayed, and that even after everything, there is underlying hope. However, in complete contrast to this Death of a Salesman’s closing scenes portrays Willy’s funeral. His constant dream-like existence is finally exposed to show Willy for who he really was. The reality is enforced and everything dream-related has died with Willy, leaving the harsh truth. In both plays, dreams and escapism are used thoroughly to uplift the tragic reality of the era in which the plays are set. Although, different strategies in both are used to cope with harsh realities they both provide a form of escapism for the characters and audience alike. Whether this is the humour, drink, sex and drugs present in Road or the constant reliance on the past and denial of present reality featured in Death of a Salesman.

Motivational Methods Paper Essay Example | Topics and Well Written Essays - 1250 words

Motivational Methods Paper - Essay Example This essay principally has concern on the motivational techniques that managers apply when introducing change to their employees (Intuition Learning and Development). Herein is the importances of applying motivational techniques to the employees as well as to the organization. Further, the essay brings to light the impact of change to particular individuals. Finally, the essay introduces the best means of improving motivational techniques to impede negative results when aspiring to introduce change. Motivation refers to the desire of individuals to enable others be able to perform tasks in an expert manner. Downsizing departments refer to the task undertaken by managers to reduce the number of employees within various departments. The act of downsizing department has negative results on employees. First, it reduces employee morale since those left work under pressure, as they lack knowledge about who is the next individual to leave the department (Intuition Learning and Development). Secondly, it leads to poor quality of output due to decreased morale when performing assigned tasks. The positive outcome of managerial development depends on the ability of managers to apply the best techniques of motivation. Kusluvan 340 asserts that motivation is the source of both poor and improved employee performance. Intuition, Learning and Development denotes the three major motivational techniques of use by managers. The manner in which managers treat their subordinates are of great significance to the overall performance of employees. Managers should treat their employees as individuals with dignity and aspire to establish the best ways of enhancing employee performance. There are ways managers ought to take in when desiring to treat employees well. To begin with, managers should know what best motivates employees (Intuition Learning and Development). Having favorable knowledge about employee motivation needs results in less resistance when enacting changes within the

Making the case for employee wellbeing in a manufacturing organisation Thesis Proposal

Making the case for employee wellbeing in a manufacturing organisation - Thesis Proposal Example This paper briefly looks into the importance of employee wellness for a large manufacturing organization. In a large manufacturing organization, the employees function like the rings in a chain. As we know, if any one ring goes out of order or damaged in a chain the strength and cohesion of the chain will be lost. Same way in a large manufacturing organization the production processes are linked together. For example consider a tire manufacturing unit which normally may have three divisions; mixing, building and curing. If the mixing people fail to deliver the product in time, tire building will be affected whereas if the building people fail to complete their duties in time curing will be affected. Thus all the employees in a manufacturing unit complement each other in order to attain maximum productivity. â€Å"In situations where pressures to work longer hours are higher, where employees feel overloaded and where managers place stronger demands on personal time, employees are likely to experience greater dissatisfaction with their jobs, higher stress and fatigue, and greater work—life imbalance. (Macky, 2008) Employees under stress or bad health condition may underperform in an organization which will adversely affect an organization especially a big manufacturing organization. If one of the employees deliberately slows down things, it can affect the entire production activities of the unit. So there is nothing wrong in organizations investing heavily for developing or improving the facilities for the workforce at workplaces. Employees should feel a deep relationship with the organization in order to avoid unnecessary absenteeism or taking unnecessary sick leaves. If the employee considers the organization as his own, then he may refrain from activities which negatively affect the organization for which he is working. But in order to develop such deep relationship with the

Oil Is Hindering Development In the Middle East Region Essay

Oil Is Hindering Development In the Middle East Region - Essay Example This essay stresses that over a long time since the discovery of oil, politics has assumed central place in the exploration, drilling and trade in oil products. This has been due to great economic significance of oil and its being the most depended source of energy. The focus on oil has been immense and concentrated to the extent that deaths and destruction of properties result. This has been to the struggles witnessed between groups of personalities or organizations to exercise exclusive rights of over oil. Efforts by politicians, autocrats and scientists to explore and find other sources of energy with specific intention of decentralize focus and dependence on oil has proved futile. Oil is too important and sweet to ignore in favour of other sources of energy. This paper makes a conclusion that the Middle East region has a great history of endowment with huge reserves of crude oil and natural gas. Oil is in its simple form a black gold that can make a country achieve quick and advanced development. Unfortunately, oil in Middle East equals resource curse that results to negative development despite plenty of natural resources with huge potential to raise big revenues. Various theories contribute to the dwindled development that most of the Middle East countries including Yemen, Syria and Iraq among others are facing. The theories include but not limited to authoritarianism, Islamism, rentier states, dependency, regional and global power politics on oil.

Essay Example This study goes further and defines performance as the actions of a speaker. Performance is the situation where a speaker is able to convey information through actions. In Brown’s report, competence has been referred to as i-language, which is the language in the brain. This is similar to the earlier definition of competence. Bloom also defines performance as e-language. This refers to language that is externalized. According to the three perspectives, performance is the actual saying of a word or a sentence. This is the sound that is articulated and made. Competence is the ability of a speaker to produce a word or a sentence. It is what is known about a word or a sentence. Linguistics has been described as the science that study language. This is because Linguists carry out experiments to obtain results that act as a basis for the various conclusions made about different aspects of language. The difference between descriptive and prescriptive approaches to language has also been brought out clearly. We see that the descriptive strategy normally has its basis on the past. It makes conclusions about a certain language depending on past state of issues. On the other hand the prescriptive strategy puts all factors into consideration while analyzing various criteria. The prescriptive strategy takes the second best option in choosing the strategy that could be applied realistically. A synchronic view to linguistics has been explained as a view that analyses a linguistic phenomenon at a given time (Aitchison,j.1992). On the other hand, diachronic analysis considers a certain phenomenon in terms of changes that have taken place over a given time duration. These definitions appear to be almost similar in the three cases that have been

Account for the failure of the experiment in constitutional monarchy Essay

Account for the failure of the experiment in constitutional monarchy between 1789 and 1792 - Essay Example By late 1792, the rule of monarchy was overthrown and replaced by the first French Republic. The vision of an ideal society in which the government worked for the good of the nation and not for individual interests was the driving force behind the political ideas of the French revolutionaries (Hanson, 2004: 4). This paper proposes to account for the failure of the experiment in constitutional monarchy between 1789-1792 during the French Revolution. Further, the extent to which the attitude and behaviour of the king were damaging to the monarchy, and the significance of the development of a more radical strand of politics will be determined. Until 1789, hereditary monarchy which is also known as absolute monarchy was the norm in France, as in other parts of Europe. Though there were no constitutional restraints, every ruler operated within certain constraints. However, several difficulties were commonly experienced by thr rulers such as poor communications, lack of information, absence of a trained civil service which made reforms difficult to implement, resistance to change by vested interests, etc (Simpson, 2000: 11). The representatives of the third estate who took the new title of National Assembly, demanded that France should have a constitution, a set of rules by which it would be governed, and which even the monarch would have to obey. A large part of the first National Assembly’s legislation became incorporated in the Constitution of 1791. It was agreed that the monarchy should remain, which was to be a new constitutional monarchy, stripped of former absolute control over government, legislation, army and justice. Actual power would lie in the hands of the National Assembly itself, with unlimited powers over taxation, authority in all legislative matters, limited only by the requirement to hold elections every two years. The new constitutional

Historiographical perspectives of the Cold War Essay

Historiographical perspectives of the Cold War - Essay Example While the explanations of the origins of the conflict in academic discussions are complex and diverse, several general schools of thought on the subject can be identified. Historians commonly speak of three differing approaches to the study of the Cold War: "orthodox" accounts, "revisionism," and "post-revisionism." Nevertheless, much of the historiography on the Cold War weaves together two or even all three of these broad categories. The first school of interpretation to emerge in the U.S. was "orthodox". For more than a decade after the end of the Second World War, few U.S. historians challenged the official U.S. interpretation of the beginnings of the Cold War. This "orthodox" school places the responsibility for the Cold War on the Soviet Union and its expansion into Eastern Europe. Thomas A. Bailey, for example, argued in his 1950 America Faces Russia that the breakdown of postwar peace was the result of Soviet expansionism in the immediate postwar years. Bailey argued Stalin violated promises he had made at Yalta, imposed Soviet-dominated regimes on unwilling Eastern European populations, and conspired to spread communism throughout the world. From this view, U.S. officials were forced to respond to Soviet aggression with the Truman Doctrine, plans to contain communist subversion around the world, and the Marshall Plan. U.S. involvement in Vietnam in the 1960s disillusioned many historians with the premises of "containment", and thus with the assumptions of the "orthodox" approach to understanding the Cold War. "Revisionist" accounts emerged in the wake of the Vietnam War, in the context of a larger rethinking of the U.S. role in international affairs, which was seen more in terms of American empire or hegemony. While the new school of thought spanned many differences among individual scholars, the works comprising it were generally responses in one way or another to Williams' Apple man landmark 1959 volume, The Tragedy of American Diplomacy. Williams challenged the long-held assumptions of "orthodox" accounts, arguing that Americans had always been an empire-building people, even while American leaders denied it. Following Williams, "revisionist" writers placed more responsibility for the breakdown of postwar peace on the United States, citing a range of U.S. efforts to isolate and confront the Soviet Union well before the end of World War II. According to Williams and later "revisionist" writers, U.S. policymakers shared an overarching concern with maintaining capitalism domestically. In order to achieve that objective, they pursued an "open door" policy abroad, aimed at increasing access to foreign markets for U.S. business and agriculture. From this perspective, a growing economy domestically went hand-in-hand with the consolidation of U.S. power internationally. "Revisionist" scholars challenged the widely accepted notion that Soviet leaders were committed to postwar "expansionism". They cited evidence that the Soviet Union's occupation of Eastern Europe had a defensive rationale, and that Soviet leaders saw themselves as attempting to avoid encirclement by the United States and its allies. In this view, the Soviet Union was so weak and devastated after the end of the Second World War as to be unable to pose any serious threat to the United States; moreover,

World History - Essay Example success re-emergency of the Japanese economy as world-class after the end of World War II is the role played by the Ministry of International Trade and Industry {MITI} and its minister Ikeda Hayato who went on to become Prime Minister of Japan. The role of MITI in the ‘Japanese miracle’ is lauded by many scholars as â€Å"no other governmental regulation or organization had more economic impact than MITI.† MITI also gained special attention in Chalmers John’s 1982 book ‘MITI and the Japanese Miracle: The Growth of Industrial Policy, 1925-1975’ where he praised it as â€Å"the particular speed, form and consequences of Japanese economic growth are not intelligible without reference to the contributions of MITI.† Ikeda Hayato became Japanese Prime Minister in 1960 at a time when the economic efforts of MITI {in which he was very much involved} were nearing full bloom. He went on to support and supplement MITI policies. His tremendous invol vement in the ‘Japanese miracle’ led Chalmers Johnson to refer to him as â€Å"the single most important individual architect of the Japanese economic miracle† in his 1982 book (Wikipedia.org). MITI, which was formed in 1949, started off with the ‘Policy Concerning Industrial Rationalization’ in 1950 that officially validated cooperation between the Japanese government and the Japanese private industry. An important aim of the Policy was to negate and overcome the effect of the deflationary regulations put in place by the ‘Supreme Commander of the Allied Powers’ {SCAP} immediately after World War II. The overall aim of the Policy was to stabilize the many industries of Japan and guide them towards the single target that envisaged national production goals and private economic interests (Wikipedia.org). The second major step taken by MITI was the passing of the ‘Foreign Capital Law’ in 1950 that disengaged and separated the import of technology from the import of merchandise. This Law gave MITI sole and full

Ethnicity and the Immigrant Experience Essay Example for Free

Ethnicity and the Immigrant Experience Essay When thinking about immigration, most individuals imagine all different types of ethnic groups traveling to a separate land away from their own. Most imagine America. Immigration, throughout history, has occurred within all types of ethnicities. When taking a closer look at the individuals living in America, it is apparent that everyone is not exactly like one another. Assimilation becomes a popular word used when discussing migration, and both positives and negatives come along with it. Two theorists that discuss the meaning of assimilation in their writings are Stephen Steinberg in his book, Ethnic Myth, and Milton Gordon in his book Assimilation in American Life. They discuss issues regarding assimilation and how they affect the nation as a whole. A novel written by Chang-Rae Lee titled, Native Speaker, gives specific examples as to how the assimilation process affects others and the migrants themselves, as also described in both Steinberg and Gordon’s books. In Steinberg’s book, Ethnic Myth, he discusses with his readers the issues regarding ethnic identity and assimilation. This is presented and explained in the chapter titled, The Atrophy of Ethnic Cultures. He first talks about the idea of the â€Å"melting pot† and how it should not be analyzed lightly. He gives a quote from John Higham that says, â€Å"Loud assertions of pluralism almost invariably betray fears of assimilation† (Steinberg, 59). This means that minority groups that try to maintain their cultural traditions may, in fact, risk assimilation by doing so. Another point he brings to the surface is that when looking back at second or third generations of a specific minority group, these people still can relate back to their original traditions and culture identity. He then says, â€Å"But can the same be said of the new generation which has known only the Americanized version of the original culture?† (Steinberg, 60). This is an obvious prevailing issue when it comes to preserving ones culture. An example within the novel, Native Speaker, would be when Henry, the main character described as a Korean immigrant, explains the history with his father. His father, living in America, would gather with friends and participate in ggeh’s, or â€Å"money clubs.† Here they would win money and eventually, that is all that mattered to the Korean group. The shift from typical Korean traditions to owning all this land and money in American became a vast transformation. Henry says about his father, â€Å"In America, he said, it’s even hard to stay Korean.† These alterations from one ethnic experience and tradition to another can be lost very quickly and potentially never be replenished. Throughout both Steinberg and Gordon’s writing, they both have similarities and differences when regarding assimilation. Gordon talks about these â€Å"ethnic meetings† which refer to assimilation. Throughout Gordon’s chapter titled, The Nature of Assimilation, he gives a numerous amount of definitions from theorists and writers that differ in various ways. In an essay that Gordon leaves the author anonymous in this chapter defines assimilation as â€Å"the process by which different cultures, or individuals or groups representing different cultures, are merged into a homogenous unit. Here Gordon talks about assimilation as positive, whereas Steinberg takes a different approach. Steinberg suggests that assimilation is not always a positive aspect simply because it can result in the loss of a cultural identity. This is present in Native Speaker because Henry continuously tries indulging himself into American culture. He cannot fully accomplish this, which essentially results in his wife, Lelia, leaving him in the beginning of the novel. As there are differences within Steinberg and Gordon’s readings, they do agree upon their understanding of the nature within assimilation. Gordon says that cultural behavior changes â€Å"may take place in the cultures of either one of the two groups, or there may be a reciprocal influence whereby the cultures of both groups are modified† (Gordon, 62). Steinberg agrees with this statement because he suggests that the changing of one’s culture is at high risk when incorporated into a different culture. He says, â€Å"The ethnic crisis only begins with the fact that the core elements of traditional culture have been modified, diluted, compromised, and finally relinquished† (Steinberg, 62). Both writers describe this lack of identity in one way or another. Assimilation is apparent in any society, especially America. People of different backgrounds continuously trying to come together to create one nation is a crucial aspect in society today. Steinberg, Gordon, and Lee all discuss how assimilation has issues when it comes to preserving ones ethnic traditions and identity. What they all convey to readers however, is the fact that the merging of cultures will forever be essential and inevitable. Works Cited Steinberg, Steven.

Formation and Drainage of Supraglacial Lakes

Formation and Drainage of Supraglacial Lakes Glacial Processes and Geomorphology Degree Assignment B028303 What controls the formation and drainage of supraglacial lakes on the Greenland ice sheet and to what extent are these processes an important control on ice sheet dynamics? Introduction The Greenland Ice Sheet is a large ice mass in the Northern Hemisphere, made up of both land terminating and tidewater terminating outlet glaciers. Seasonal surface melting produces melt water that collects on the surface of the Greenland ice sheet in the form of supraglacial lakes (Luthje et al., 2006). The storage and drainage of lake water is particularly important in forcing a hydraulic connection between the ice sheet surface and the ice bed interface (Bartholomew et al., 2012). For this reason, drainage of these supraglacial lakes is of particular interest in understanding the influence that they have on ice sheet dynamics. Supraglacial lakes have been known to drain in less than one day (Box Ski, 2007). The fluctuations in surface water delivered to the glacier bed from the rapid drainage of these lakes are known to affect the speed that the ice sheet travels at and have been known to cause local uplift of the ice sheet (Sundal et al., 2011). The purpose of this paper is to discuss the factors that control the formation and drainage of supraglacial lakes on the Greenland ice sheet and the implications these processes have on the control of ice sheet dynamics. Formation In cases where drainage is prevented, melt water can be stored on the ice sheet by a form of sediment or ice barrier, creating a supraglacial lake (Benn Evans, 2010). Seasonal warming produces melt water that collects in closed surface undulations on the surface of the ice sheet. The supraglacial lakes across the Greenland ice sheet vary in size from a few hundred meters to 1500m in diameter, with depths of 2-5m (Box Ski, 2007). Supraglacial lakes form in the ablation area of the Greenland ice sheet during summer time melt season. Positions of numerous lakes have been monitored over many years and from the results it can be deduced that most lakes form in the same place every year (Luthje et al., 2006). Supraglacial lakes can occur across much of the ablation zone on the Greenland ice sheet but are especially prominent on the Western transect (Luthje et al., 2006). The formation and location of supraglacial lakes on the Greenland ice sheet is driven by season and temperature, elevation and topography (Chu, 2014). There is an upper limit imposed on the lake distribution and formation by elevation because of temperature and basal sliding restrictions (Liang et al., 2012). Due to the lapse rate, temperature decreases with elevation. When it reaches a certain point on the ice sheet it becomes too cold for melting to so there is no melt water for filling the lake basins. As bedrock topography is only expressed in ice surface topography in regions experiencing basal sliding, interior regions of the ice sheet that do not experience basal sliding are unlikely to contain ice surface depressions suitable for lake formation (Liang et al., 2012). Figure 1(a) shows a histogram of the rate of change of lake area over 10 years of observations. In (b) only the 50th percentile shows a significant relationship with melt intensity. From the two graphs it can be deduced that there is a positive correlation between annual median lake elevation and annual melt intensity, indicating that lakes are more active at hi gher elevations during warmer or more intense melt years (Liang et al., 2012). During more intense melt years, lake drainage events become more common in higher elevations. These regions, which don’t normally experience rapid surface water transfer to the bed of the glacier become more susceptible to moulin formation (Liang et al., 2012). Only lakes above 1050m show inter-annual changes in response to seasonal changes in melting intensity (Liang et al., 2012). The area of supraglacial lakes is more controlled by the local topography. Lakes at lower elevations tend to be smaller because the steeper ice surfaces prevent as much water being collected and stored (Bartholomaus et al., 2007). Although topography and elevation influence the formation and distribution of supraglacial lakes in Greenland, the main control is the season. The lakes will only form during melt season, when temperatures become warm enough to produce melt water to fill the empty lake basins (Luthje et al., 2006). Drainage In order for melt water stored as supraglacial lakes to reach the bed of a glacier, a through ice transport system is required. In a study, Das et al. (2008) monitored and observed the rapid drainage of two large supraglacial lakes down to the base of the Greenland ice sheet. The lakes, on the Western side of the Greenland ice sheet began filling in early July, reaching maximum extent around the 29th of July. At first, lake levels began to fall slowly and steadily and then levels dropped rapidly. This rapid drainage event drained the lake in around 1.4 hours (Das et al., 2008). From observations, it can be deduced that the drainage of the lake occurs in four stages. First of all initial slow, steady drainage occurs through crevasses (Chu, 2014). No water reaches the bed of the glacier, suggesting an inefficient drainage system. Next, connection to the bed occurs and drainage through a fracture system occurs. This stage gives fast and direct drainage of the lake to the bed of the glacier. Thirdly, Moulin formation and closure of the fracture system occurs. Frictional heating from the turbulent water flow and rapid drainage in stage two melts through fracture walls, developing them into discrete moulins (Chu, 2014). Moulins are associated with rapid lake drainage and immediate transfer of water to the ice sheet (Chu, 2014). This rapid transfer of water to the glacier bed has potential to overwhelm the subglacial hydrologic system. The final stage occurs once the lake has drained. Moulins stay open to allow the drainage of surface melt to the bed of the glacie r (Das et al., 2008). Evidence suggests that moulins in existence in the bottom of the lakes fill with snow and become dammed in the winter. Lakes are filled during the summer melt season until the moulins are reopened by a combination of pressure and melting (Box Ski, 2007). Fracture propagation through the ice suggests that once initiated water filled crevasses will propagate downwards through the full thickness of the ice through a process called hydrofracture (Das et al., 2008). The water ponds above small crevasses in the lake basin, exerting stress on the crevasse and eventually the ice starts to fracture. Initially the water refreezes in the crevasse. Heat created from refreezing warms the ice and it melts, advancing further down into the crevasse. Once a connection with the bed is established water from the lake can freely drain. There is no limit to the depth of a water filled crevasse so it is able to reach the bed of a glacier. The process is only limited by the supply of melt water needed to keep the crevasse full (Weertman, J. 1973). Crevasses and moulins connect the surface of the ice sheet with englacial environments, providing a route for melt water to drain from the supraglacial lakes through the ice sheet (Chu, 2014). Although only lake drainage processes for two lakes were observed by Das et al. (2008) in this particular study it can be assumed that other lakes on the Greenland ice sheet drain in the same way. The presence of fractures in other empty lake basins suggests that drainage processes are similar for all supraglacial lakes (Das et al., 2008). Throughout melt season, drainage patterns of the lakes across the Greenland ice sheet migrate inland. Lakes at lower elevations tend to form and drain earlier than those at higher elevations (Bartholomaus et al., 2007). Ice Sheet Dynamics Rapid drainage events are of particular interest in understanding ice sheet dynamics and hydraulic response. Fluctuations in surface water are known to affect the speed of ice sheets (Sundal et al., 2011). Some suggest that more influx of melt water to the glacier bed, from lake drainage events could produce ice sheet acceleration. Moulins provide a method of rapid lake drainage, supplying large influxes of water to the glacier bed with the potential to overwhelm the subglacial hydrological system causing uplift and increase basal sliding (Chu, 2014). They can only support a fraction of the lake water, keeping water pressure at the base of the glacier high and encouraging increases in basal movement and uplift (Box Ski, 2007). Higher water pressure favours faster sliding as it reduces drag between ice and the bed (Bartholomew et al., 2012). Speed ups of the ice sheet are caused by an increase of water pressure at the its base, enhancing basal sliding. This increase in basal water pressure can be provided by melt lake outbursts (Box Ski, 2007). There are other processes involved in basal sliding but for the purposes of linking it with glacier hydrology we are only interested in cavitation. Cavitation vertically jacks the glacier upwards, reducing friction between the glacier bed and rock interface and decreasing effective pressure. When effective pressure and friction are low basal sliding rates are high. In the same study as mentioned above, Das et al. (2008) observed horizontal and vertical movement of the ice sheet that coincided with rapid drainage of the lake. A large uplifted block of ice in the centre of the lake basin evidences local uplift of the ice sheet during rapid lake drainage. Based on topographic studies, it is likely that the large block in the centre of the lake was uplifted during a drainage event (Das et al., 2008). The elevation change reported by sonar surveys suggests surface uplift of around 6m across the block. The large volume of water transported to the ice sheet bed during lake drainage would have produced several meters of uplift at the lakes centre (Das et al., 2008). Figure 2, produced from a study by Bartholomew et al., (2012) supports Das’ et al., (2008) conclusion that drainage of supraglacial lakes can affect velocity and uplift the ice sheet. It shows rapid increases in ice velocity and surface height after the drainage of a supraglacial lake observed on the Western transect of the Greenland ice sheet. Drainage of the lake can be linked with a 400% increase in ice velocity and 0.3m of uplift in less than 24 hours (Bartholomew et al., 2012). Figure 2: (a) Surface velocity during lake drainage event (b) Surface height profile during the lake drainage event (c d) Before and after images of the supraglacial lake (taken by time lapse camera). Solid black lines on (a b) indicate the times when the two photos were taken. Taken from: Bartholomew, I., Nienow, P., Sole, A., Mair, D., Cowton, T. and King, M. (2012). Short term variability in Greenland Ice Sheet motion forced by time-varying meltwater drainage: Implications for the relationship between subglacial drainage system behaviour and ice velocity. Journal of Geophysical Researcg, 117(F3). Both outlet glaciers and slower moving ice sheets across Greenland show a seasonal speed up in response to enhanced melt water delivery to the glacier bed and from pulses of water from lake drainage. The ice sheets continue to speed up until a maximum velocity threshold is reached; sequentially the glacier slows down (Chu, 2014). This slowing down of the glacier is not to be expected if lubrication by melt water is the primary mechanism of speeding up the ice sheet. The reduction in velocity suggests subglacial drainage switches from a linked cavity system to a more efficient channel drainage system (Chu, 2014). Conclusion Understanding the hydrology of supraglacial lakes is important as they have the potential to supply large volumes of water to the bed of the ice sheet and affect motion. Both an increase in glacier velocity and local uplift is observed when supraglacial lake water drains to the bed of the glacier. However, constant high influxes of water are not consistent with continued increase in velocity because the subglacial drainage system switches to a more efficient system (Bartholomaus et al., 2007). Large pulses of water delivered to the bed from drainage of supraglacial lakes overwhelm the subglacial hydrologic network and increase basal motion. Moulins provide rapid drainage of large supraglacial lakes into the ice sheet hydrological systems, while crevasses provide a more steady drainage method. The location, area and potential melt water available to fill these supraglacial lakes is controlled by the elevation and topography of the surrounding area, and more importantly temperature. In turn, these factors could be controlled by climate change. For this reason it is important to monitor the processes associated with glacial lakes to get a clearer understanding of the impacts any future climate change will have on glacial lakes and the Greenland ice sheet.

United States and French Relationship Essay -- World Politics Politica

United States and French Relationship Freedom fries and Chanel boycotts should not be dismissed as isolated and juvenile posturing on the part of the American people. Rather, the visceral reaction to French reluctance to follow the Bush administration into Iraq should be addressed as a substantive and not simply cosmetic distrust Americans share of the French. Kantian country In France, the â€Å"renegade cowboy† George W. Bush is anathema to a country more comfortable with shades of gray than the black and white lenses with which the United States views the world. The US and France rarely see eye to eye on cultural and political issues simply because we do not share the same world view. American eyes view the â€Å"outside† a bit differently than the French and this is at the root of most foreign policy differences. The Hobbesian view of man, largely based on Judeo-Christian beliefs that led to the famous â€Å"axis of evil† appellation, grates French ears. Further, while most French nationals speak a foreign language, travel extensively, and consider themselves global citizens (but alas, are not tous amà ©ricains), recent allegations that John Kerry â€Å"looks French† and even speaks the language have reminded us all that antipathy towards the French and xenophobia persist. Alain de Chalvron of France 2 explains, â€Å"for us, to speak any other language and have an open view of the world, for a President, should be a plus† (Kurlantzick).

Survey of Wireless Computing :: Wireless Technology Networks Computers Essays

Survey of Wireless Computing Abstract Wireless technology can provide many benefits to computing including faster response to queries, reduced time spent on paperwork, increased online time for users, just-in-time and real time control, tighter communications between clients and hosts. Wireless Computing is governed by two general forces: Technology, which provides a set of basic building blocks and User Applications, which determine a set of operations that must be carried out efficiently on demand. This paper summarizes technological changes that are underway and describes their impact on wireless computing development and implementation. It also describes the applications that influence the development and implementation of wireless computing and shows what current systems offer. 1 Introduction Wireless computing is the topic of much conversation today. The concept has been around for some time now but has been mainly utilizing communication protocols that exist for voice based communication. It is not intended to replace wired data communication but instead to be utilized in areas that it would be otherwise impossible to communicate using wires. Only recently has the industry been taking steps to formulate a standard that is more suitable to data transmission. Some the problems to be overcome are: (1) Data Integrity - relatively error free transmission, (2) Speed - as close as possible to the speed of current wired networks, (3) Protection - making sure that the data now airborne is encoded and cannot be tapped by unwelcome receivers, (4) Compatibility - ensuring that the many protocols that sure to be created subscribe to a standard to allow inter-operability, (5) Environmentally safe - strengths of electromagnetic radiation must be kept within normal levels. In our study of the theories and implementation concerns of wireless computing, we found that it is being treated in an object oriented fashion. Scientists and development crews, including the IEEE, are doing their best to implement wireless connectivity without changing the existing computer hardware. As a result, a lot of focus is on using existing computer hardware and software to convert data to a format compatible with the new hardware which will be added to the computer using ports or PCMCIA connections that already exist. This means that wireless communication will be transparent to the user if and when wireless computing is utilized on a wide scale. Wireless computing applications covers three broad areas of computing today. Replacement of normal wired LAN's need to retain the speed and reliability found in wired LAN's. Creation of semipermanent LAN's for quick and easy setup without the need for running wires. This would be necessary for events such as earthquakes. The last category is that of mobile computing.

The Prostitution Industry Essay -- Prostitutes Sexual Services Sex Ess

The Prostitution Industry A prostitute is defined by the Oxford Advanced Learner’s Dictionary as â€Å"a person who offers herself / himself for sexual intercourse for money.† Legally, prostitution is the sale of sexual services. The services may consist of any sexual acts, including those which do not involve copulation. While payment may be any nonsexual consideration, most commonly it is in the form of money. In what seems to be a world historical pattern, an upsurge in prostitution followed the effects of urbanization and wage labor. In Africa and Latin America this trend was heightened by industrial development, which greatly accelerated extensive displacement of people from traditional kinship ties. Women often supplemented their low wages with occasional prostitution, or, in the absence of employment, turned to prostitution as full-time work. Although a persistent phenomenon throughout human history, it remains difficult to view prostitution in an objective light as various cultures have alternately tried to ban it on religious or moralistic grounds, or stigmatize it under a â€Å"don’t-ask-don’t-tell† sort of veneer which was a barely-tolerated but necessary evil of society. It is interesting to note that despite an increasingly secularized attitude towards sexual relationships, as seen in society’s increasing tolerance of homosexuality or pre-marital sex, prostitution retains much of its social stigma. TYPES OF PROSTITUTION Street prostitution is the most common form of prostitution. It occurs when the prostitute solicits customers while waiting at street corners or walking alongside a street usually dressed in skimpy, suggestive clothing. This can be seen on Koinage Street in Nairobi. A variation of this is where prostitution is more open and solicitation is done at bars. Examples of this in Kenya can be seen at Florida 2000, Modern Green on Latema Road and Sabina Joy Bar and restaurant. Brothels are establishments specifically dedicated to prostitution and are usually confined to red-light districts in big cities. The clients usually go to these brothels to get sexual services. Escort or out-call prostitution often shelters under the umbrella of escort agencies, who supply attractive escorts for social occasions. In this form of prostitution the customer calls/contacts an agency and the act takes place at the client’s... ... who enter into prostitution. The prostitutes who enter the profession as a means of survival sometimes have no other option. But, if they have access to funds from micro-finance institutions, they may be able to start up small businesses to sustain their livelihood. REFERENCES †¢ Ferrell et al.

Multinational corporations Essay

Different writers are motivated by different things in their writing. In most cases life experiences, witnesses and exposure acts as a driver that urges one to enlighten the rest of the community about a given issue. In his book â€Å"Next Stop Reloville† Peter Kilborn, focuses on a special segment of people among the families that move in order to maintain or keep their job. These are the families that represent the middle and the upper management and they are described on the impact of their movement on the dynamics the family. Throughout his approach, he focuses on the aspects of the families’ lives and its relationship to their movement. For instance he provides one of the reasons relating to their movement to be due to the pressure to comfort where families seek new homes in new neighborhoods due to high resale value of the present homes. This thus creates discomfort to the families and hence they get thrilled to look for new homes outside their present locations. Kilborn therefore, takes us into the interior parts of America to see the lives of the American Relos and thus showing how the existing pressures and their effect on their own families and also the whole American community. The Relos that Kilborn describes include first the hard striving class that is continuously migrating in the suburbs of Dallas and Atlanta and also the expatriate villages of Bombay and Beijing. He shows the costs and the loneliness issues that engulf their lives and also he notes how the free fall in the housing prices affects their movement hence making them less mobile (Kilborn, 2009, 31). The Relos’ ways of life is seen to have a negative effect on the affected communities. They do not plan to stay for a long duration of time and because of this they do not get involved in any charitable causes, but on the other hand they have an effect on the real estate. Since they do not bother in bargaining and the fact that their employees keep money for their move, they are prone to driving the home prices up. Therefore, as they move from state to state they create a portable culture that has an effect in the American society at large. The effect of the Relos on the American society can be seen on the case of the subdivisions of Atlanta, Pittsburgh and Dallas. This is where there is an unusual similarity in the houses layout. There are some little houses that cost a million dollars and above and the fact about this place is that no one lives in them for about three to four years. This place represents the home of the Relos where there is the existence of the middle level growing companies. Their existence depends on those willing to uproot their families for the sake of professional success thus living in a social class of insecure and travelling families. The families are driven by one person who is usually the father of the house. There is an experienced movement of people from home due to the change in economy and as many places becomes industrial centers. Many parents are prone to giving their family ties and move to town to remain as a single unit. As the Relos keep on moving, their family becomes unable to move with them thus leading to their separation from their families (Kilborn, 2009, 38). There are also some broader effects of this kind of lifestyle on the American society. The Relos shape and define the neighborhoods as they exert the multiplier effect on the face of the local communities. This is done by their acts of buying and selling homes within a small duration of less than three to four years thus providing better business for the home owners by selling to the people who come to stay in the town. The issue of homes brings about many effects on the public policy. Some of the effects of this include the insufficiency of the walk-able downtowns, the exclusion of the high income and low income housing, and the high degree of segregation of income. There is also a reported degree of the effects on the isolation of poverty in the United States. This is because they are known to be the well paid personalities of many of the international companies who sometimes collect markets that offer transportation facilities for the employers into multinational corporations. They take up the larger portion of the America’s national income thus promoting poverty. Therefore, the Relos have so far been blamed for the increase in the increase in the prices of houses in towns thus affecting the American citizens’ ability to live and pay for the houses at their prevailing normal prices. They are also being blamed for increasing the level of poverty in the country by taking most of the jobs that should have remained for the non-relocating citizens who are in contact with their families (Kilborn, 2009, 76). On the side of the family structure, there has been experienced a breakdown in the family ties thus leaving the families leading a loneliness life which is unsecured by the family members. Finally, the political structure of the American community is being affected due to the instability of the family structures. All these circumstances are being supported from the author’s views on the Relos life in the United States. Bibliography Kilborn, Peter, T. 2009.

Medical Marijuana Essay Essay

The issue on legalizing marijuana is a very controversial topic in the U.S. and all around the world. This is an issue for the fact that some people are being denied medical treatments just because marijuana has been illegal and misunderstood for so long. For as long as anyone can remember medical and legal marijuana has been seen in the negative side of the news and bad opinions by the general population. In recent years people, local governments, and state governments in the United States have been speaking out and is changing the way many people are viewing marijuana in this paper we will discuss the financial, medical, negative and positive effects of marijuana. Ways that you can fix this issue are contacting your local and state governments and expressing your opinions on this issue. First, look at the way America is viewing the legalization of marijuana. Marijuana now being fully legalized in Colorado and Washington, also with 23 states making it legal for medical purposes and 6 others decriminalizing the drug is now on a different path with legalization. â€Å"Owners of the 37 new dispensaries around the state reported first week retail sales to The Huffington Post that, when added together, were roughly $5 million.† (Frener, 2014). As you can see the financial revenue from just one state in its first week of opening is huge. All of this money can go back into school programs, equipment for classrooms, and other community related budgets. Colorado and Washington are hopeful that they will make up to 2.1 billion in revenue for the states. Uses for medical marijuana have been looked down upon until recent years. Many people follow what their parents think of the drug and that it is bad or they follow what their friends think. Scientists have been researching the positive medical effects of marijuana from tests and studies. â€Å"Medical marijuana has shown positive results for epilepsy treatment, especially for patients who have physical resistance, to traditional medications. A special strain cultivated for pediatric epileptic treatment, called ‘Charlotte’s Web’ has become widely popular, with parents flocking to Colorado to get a supply for their children.† (Shim, 2014). This just shows how important cannabis can be for people and their kids in Utah. The main chemical that affects the way we feel and the main medical ingredient tetrahydrocannabinol is effective in treating chronic pain, vomiting, nausea, anorexia, and other social psychological disorders. With all of this research being found over the years we can only assume that if  legalized who knows what we can find from continued research. There is also the more serious side of medical marijuana and that is the help it has towards serious illness and diseases that cannabis has already been known to help cure. All of this knowledge has been discovered has had with major diseases such as Parkinson’s disease, major depression, HIV/AIDS, hepatitis C, and many forms of cancer. Next, many studies have been done on how much worse cigarettes are for you then marijuana. Research has been shown that cigarettes have been proven to be a lot worse for your lungs then weed. You can benefit from mari juana in many ways smoking it is the worst but quickest way to get the effect. Some people use vaporizers so it won’t be as harmful on their throat and lungs. The healthiest ways to take in the medicine is in an edible or pill form. Another thing that makes smoking cigarettes a lot worse than smoking marijuana is the addictive effects of nicotine that marijuana doesn’t have. In the year 2012, someone was arrested for marijuana related crimes every 42 seconds. If you really think about it that’s almost one person a minute, or 60 people every hour and so on. Now look to the next year and our current year. Crime rates have plummeted in Colorado in late 2013 and in 2014 basically are non-existent. â€Å"While marijuana prosecutions against people over 21 declined, so did prosecutions against people under 21, for whom all marijuana possession remains illegal except for medical marijuana patients. Colorado Attorney General John Suthers said he thinks the drop in cases may be due to police not wanting to parse the complexities of the state’s marijuana law.† (Ingold, 2014) People in the United States pay around 8% tax revenue to keep prisoners in custody. Many of these people are only there f or a minor crime of selling or in possession of marijuana. If marijuana were to become legal, many of these people would have a better time finding a job, save America millions of dollars, and these peoples’ lives wouldn’t be ruined over a harmless drug. Medical Marijuana could be one of the main factors to get us out of this deep recession. The United States could make so much more money by legalizing marijuana, and applying higher taxes on the marijuana they sell. One thing you might see the government doing this with is cigarettes. You may not notice the inflation of how much the tax on cigarettes go up depending on how much of a dense population will have higher tax on cigarettes. This is mainly for profits to go back into the government. If  you do the research a pack of cigarettes costs about 40 cents to make that is two cents a cigarette, but if that is the case then why are cigarettes 5-12 dollars, because depending on where you are the taxes will go up. If you are somewhere like Virginia, where cigarettes are made, y ou can get a pack for five dollars. Then there are places like New York where it can be 10-15 dollars a pack. If The United States did the same thing with marijuana who knows how much this could raise revenue. But how would they package and sell marijuana? One way the government could sell this product would be to have pre rolled joints (rolled up marijuana cigarettes) in a pack, maybe not in a pack of 20 but something smaller. So it could be sold in a dispensary but also in smoke shops and gas stations in states where it is legal that is. One of the government’s main concerns for not legalizing is the how America will view the change in laws. Something we can see is the rise in support of this drug and how it is affecting the lives of many people in The United States and around the world. People will buy marijuana even if the taxes are ridiculous as long as it’s legal I don’t think people are going to have a problem with purchasing legal marijuana. Now for the negatives, many people that are for t he legalization of marijuana might also have the mindset that marijuana doesn’t have negative effects on the brain and body. THC (tetrahydrocannabinol) is activated in the brain using cannabinoid receptors, once the THC enters your brain it hits these receptors creating your â€Å"high†. The cannabinoid receptors affect the parts of the body that have to do with memory, pleasure, organized thought, senses, and time perception. Marijuana causes health risks in the heart and lungs depending on how you choose to consume the drug. â€Å"THC messes with brain areas called the cerebellum and basal ganglia, which regulate balance, posture, coordination, and reaction time. When these brain areas are disturbed, the user has a harder time walking and talking correctly, becoming quite clumsy. It also impacts their ability to drive† (Welsh,Spector, 2013). . The lungs also experience burning and stinging in the mouth and lungs when marijuana is smoked. Studies have also been done to see the effects of sleep, and they say that if you go to sleep high it can interrupt one of the 5 stages of sleep and make i t so you don’t get as much sleep. One thing that the government is worried about when legalizing marijuana is it can put a damper on the financial benefits of legalization of at home growing. If the drug is legalized what is to stop people from growing their own? Laziness, what percent of Americans grow and raise their own food so what makes them think they will grow their own weed? On the other hand growing this plant is not very hard. This will always raise more questions for the people. Will there be laws against growing your own? How will they regulate that? The government will always find a way to benefit from your happiness. In conclusion, marijuana is slowly creeping its way into our lives one way or another. If it is legalized for the financial benefits to help The United States get out of its recession, to financially help out communities by putting the revenue into our schools, parks, or general community improvement. Even if it is only legalized for one of its countless medical benefits from cancer, depression, anxiety, HIV/AIDS treatment, or to help someone get over an eating disorder. Now there is always the possibility that America won’t legalize for negative health reasons, or social shaming from other Americans. The amount of states getting bills, setting boundaries, making laws, and opening up, are phenomenal. Get ready, legalization could be closer than you think. References Armentano, P.

Comp 2 Argumentive Essay

Argument Essay To be able to complete a family most couples have children after marriage. I believe that a child should complete a parent’s life. On the other hand I don’t believe that it is biblically right for homosexual couples to be able to adopt a child and raise that child. In the bible God created man and woman for a purpose. This purpose was to be able to reproduce the population and for one man to be in love and with one woman. I do not believe that in a homosexuality house hold that a child would be raised properly and normally like most children are able to be raised.I feel putting children in that environment is suggesting that homosexuality is okay and it truly isn’t when in terms of the bible. This sin was so important to God that he directly approached the subject in the bible saying it is a sin and that a man should be with a woman and a woman should be with a man. Being a huge supporter of the Christian faith because I am apart of that faith, I b elieve that being a homosexual is dishonorable and truly upsets God.On the other hand I am aware that not every heterosexual home in the world is a stable and a suitable home to raise a child in. In many homes in this world there are children that are beaten, raped, hungry, and also very poorly supported. In those terms and in those cases I do believe that it may be acceptable for a child that are in those conditions to be placed in a home where they will be loved and supported and be loved. I do also agree that a homosexual couple is very capable of loving and providing and taking care of a child.If the child is being beaten and unloved and raped and other extreme conditions I would be supportive and feel that it was okay for a child to be adopted into a homosexual home. I also feel that it is hard for the children that are being adopted to be able to accept what is going on and being able to know what is natural and taboo. Same-sex couples raising children must stand ready to prov e to the world they are a family, just one that happens to have two mothers or two fathers. For example I would like to share this one homosexual couple’s tory. This constant burden of proof is especially difficult for families like the Muzingos, who live in a state that doesn’t allow them to establish legal ties to each other. Michelle Muzingo was in the delivery room when her wife, Katrina, gave birth to each of their three children, who are now 7, 4 and 1. She cut their umbilical cords and was the first to hold the children, who call her â€Å"mommy. † Yet because they live in Ohio, a state that does not allow gay couples to adopt, she is unable to make that title official. We are always scanning the circle around us to see what we need to put in place to protect ourselves,† said Katrina, 37. A report released earlier this week illustrates just how vulnerable these couples and their children are, both legally and financially. After all, 30 states do not have laws that allow same-sex parents to either adopt, while six states restrict them or impose outright bans. Even families who live in states that recognize their relationships can run into trouble if they travel or move.And if something were to happen to a parent who was unable to adopt or otherwise establish legal ties, the child might be denied certain federal benefits something that children of most heterosexual parents receive automatically. When having a child normally, with one man getting one woman that is married pregnant, it can be an extremely rocky road. Also I believe that not every home is perfect and there are many problems within each family. But I just think that too many complications can come from homosexual couples adopting a child.

Current Events in Business Research Edit

Identifying Research Problem The first step and perhaps one of the most critical steps in carrying out cuisines research is to isolate and identify the problem. In the research study we are considering the problem identified is how a company can be assisted in accurately predicting short and long term sales forecasts by analyzing factors that affect the sales performance of its life insurance agents. By analyzing this data the goal is to produce a predictive model of agent and agency performance in an attempt to figure out the most important predictors of successful sales performance.This model would allow increased focus and training based on the predictors to maximize sales by the life insurance agents and their prospective agencies as a whole. Research Method Used The type of method used in the study is the reporting study type. Using this method the researchers considered characteristics of agents including formal education, professional education and various types of training us ed in the industry. The researchers also considered other studies in an effort to provided baseline and comparison models to use in helping develop their hypothesis.How Research is Solving the Problem This study went beyond what other studies failed to do, because it provided further analysis and comparative data to further study and investigate radioactivity. Much of the prior research seemed to only measure certain factors e. G. Behavioral, tenure, and education. This study looked at both sales and commissions for home service agents and regular agents because of the significance in number Of policyholders and leads.They study required data to be collected by contacting area agencies and having those agencies complete questionnaires on each of their sales agents with at least one year of contract. The final data was compiled from seven local agencies including Commonwealth Life Insurance Company and The Prudential Life Insurance to name a few. The study described its weakness for data that was often time hard to evaluate and not readily available or hard to measure. For instance, the study about agents with formal education, professional education and specific training showed no effect on production.The benefit of the study was that it was able to analyze possible factors that were believed to have an effect on an insurance agent's productivity. The approach of this study used two research techniques. It used basic a reporting study that summarized data to compare findings on the topic collecting their own independent analysis and used only data that was objective. The article referenced previous studies and data available on the subject, and then relied on its own findings and research. Over the years there had been research that suggested other causal affects of an agent's productivity.In this effect the study also used explanatory research because it compared prior studies and looked at the hypothesis that caused the inability to increase productivity. Th e study required data to be collected by contacting area agencies and having those agencies complete questionnaires on each of their sales agents with at least one year of contract. The final data was compiled from seven coal agencies including Commonwealth Life Insurance Company and The Prudential Life Insurance to name a few.

Analyze and Compare Ratios of West Ham Essay Example | Topics and Well Written Essays - 1000 words

Analyze and Compare Ratios of West Ham - Essay Example It has increased far more in 2011 from 2010 than that of in 2010 from 2009. But the reported percentage is not at all a good indicator of asset performance (NYU, 2012). Debt ratios Debt ratios determine the company’s over debt load an also mix of equity and debt. So these ratios evaluate the financial risk the company and its shareholders have been facing. Debt ratio is a compared unit of company’s total debt with respect to its total assets. Specifically it shows the amount of leverage the company is using. Higher debt ratio means the company is highly dependent on its leverage and the equity position of the company is very weak. So higher the ratio means more risk the company and its shareholder has been taking. Although the total liabilities of the company has been increasing over the year but the total assets also has been decreasing in similar proportion. As a result the ratio has increased more in 2011 than it decreased in 2010 from 2009. Debt equity ratio represe nts the overall status of debt of the company. It compares the total liability of the company with respect to the shareholders fund. ... The company improved a lot in terms of shareholder’s equity in 2010 than that of 2009 as it reported the shareholder’s amount of ?13,063,000 from tremendous growth from -?290,000 in 2009. But in 2011 again it has come down to huge deficit of its shareholders’ fund. So, due to the deficit of the shareholders’’ equity in two alternative years except 2010 with respect to huge liability of the company, the shares of the company have become worthless. The main reason behind this the company is highly depended on its creditors which adversely affects the interest of investors or the shareholders towards this company. Interest coverage ratio is an indicator that determines the how easily the company can pay its interest on the basis of its gross earnings before paying interest and tax. Higher the ratio means the company’s gross earning is very high and it can easily pay the interest of its outstanding debt. This company has been reporting negative g ross income i.e. loss before paying tax and interest. So has been able to pay interest expense of its outstanding debt and these have remained due or payable for the company (JMU, 2010). Liquidity ratios Current ratio represents the working capital position of the company as it is one of the important indicators of liquidity of a company. It measures the performance of the company regarding its short term ability to pay the short term liabilities of the company. The3 current ratio of the company is has been lower than 1 in all the tree consecutive years that means it has not been able to pay its liabilities as has remained lower than liabilities. Quick ratio or acid test ratio indicates that the company has enough short term

Personal Development, Self-Management and Reflection Essay

Personal Development, Self-Management and Reflection - Essay Example Introduction Part 1: Self-Evaluation, Essential Skills As described by the Applied Personal and Professional Development Module, a skill is something one can learn, and then develop with further practice, reflection and refinement. While talent is something people are born with, skills are learned throughout the course of one’s life, and then further refined down the road. An individual talented in a certain field can quite easily excel there in no time flat, and may in fact go on to dominate that field completely. Both of these are definitely assets in any field, and HE training is no exception. Given proper training, even an otherwise unremarkable individual can surpass someone who is talented but lazy. Former US President Calvin Coolidge (n.d.) said it best when he said that ‘nothing in the world can take the place of persistence’, and that nothing is more common than someone who is talented yet unsuccessful. And in this regard, I for one am proud to say that w hile my own talent may yet be questioned, my persistence and drive have always been beyond reproach. Not only do I possess ample quantities of persistence and determination, I can also say that I have other virtues such as determination and commitment in spades. As I’m sure I’ve displayed at various points throughout the course, I’ve consistently remained on task no matter what happened, and rarely ever coasted. On the flip side, my time management leaves a lot to be desired, and I may not always be objective when it comes to self-evaluation – that is, at times I tend to either deemphasize or overemphasize my achievements. Procrastination is also another habitual problem for me, especially since I often find it hard to get anything done without a healthy (sometimes even beyond healthy) amount of time pressure to get my heart racing. And as for technical skills, I possess the skills highlighted by Steven and Fallows (1998) as being among the most important , such as skills in problem-solving, planning, and communication. These are said to be among the most important of all. All other important skills one will use in his school life as well as his career are rooted on these. Part 2: Action Plan One of my shortcomings when it comes to academic skills is the use of Information and Communication Technology (ICT) in general, something cited by the UK Department for Employment and Learning (2011) to be among the essential skills for adults. As stated by its spokesperson Deidre McGill, the literacy and numeracy problems experienced by some adults have prevented them from reaching their full potential – which is exactly why they are problems within myself that need to be addressed the most. This being the case, I intend to sharpen my proficiency in making use of ICT, and am willing to take related crash courses should the need arise. Aside from this, I myself admit that I have some problems where information handling is concerned. Shei la Corrall (1998) of the University of Reading defines this as a set of skills including information sources, evaluation criteria, navigation methods, manipulation techniques and presentation issues – which is to say that I have difficulty at times in discerning which particular bits of information should be given greater emphasis, and how best to present them. That

Strategies for Change Management - Essay Example The fourth explanation defines change management as a control mechanism. (Nickols (2008)) Fred Nickels states that change management is a process that involves moving from one state to another. Change management occurs in three strategies namely the unfreezing stage, the changing stage and the refreezing stage. (Nickols (2008)) For the core units the individuals will have the how questions, for the perimeter units individuals will have the and how questions, for the buffer units individuals will have what questions and finally for top managers they will have what questions. (Nickols (2008)) In an organization there exist resistance to change; the degree of resistance will depend on the number of individuals in the organization, political issues in the organization and whether the organization depends on the people. If the degree of resistance is high then the power coercive strategy or those environmental adaptive strategies are the most appropriate strategy and if resistance is low then the other strategies are appropriate. (Nickols (2008)) Time available to implement change will influence decisions, when time is limited then the power coercive strategy is the moist appropriate but if time is abundant than the other strategies can be applied. (Nickols (2008)) The availability of experts in the organization will also affect choice, where an organization has limited number of experts then the power coercive strategy is the most appropriate but if there are experts then the other strategies can be used. (Nickols (2008)) A business opportunity with high anticipated returns will require the use of all four strategies given that the main purpose of the organization is to generate income and therefore the organization should by all means implement change. (Nickols (2008)) If in an organization the organization depends on

The Development of the Italian Opera in the 19th Century Essay

The Development of the Italian Opera in the 19th Century - Essay Example Operas origin is said to have been the celebrations which combined enormous fireworks, beautiful stage decorations, music, singing and dancing.1 These occasions occurring frequently in royal weddings and during festivities started to work themselves around specific themes by the beginning of the 16th century. Jacapo Peri, Monteverde, Francesco Cavalli and many other doyens appeared during this period. Francesco Cavallis works were the first to be termed under the name Opera. Carissimi, Scarlatti, and Handel took Cavallis name forward. By the end of the 18th century symphony and orchestra giving prominent importance to music grew enormously, pushing back the popularity of the Opera. Rossini - the retriever of the Opera sprung to action to bring back this dwindling art from to its previous glory in the 19th century. He was followed by Donizetti, Bellini, Puccini and the ever famous Verdi who is hailed as the major mastermind of the contemporary Opera. Voice was the ruler of any orchestra in the Opera’s during the early 19th century. Polyphonic writings started to lose their grip during this time. Voice clarity and simple language expressing direct views started to matter. Rossini, Donizetti, and Bellini were the three stars of the arias. Flawless phrases and singers with highly toned voices capable of singing in very high notes started to emerge. Cabaletta or rapid precision singing started gaining popularity. The operas of the early 18th century had two main sections the Bel Canto and the Cabaletta.2 Highly prerogative stories insisting patriotism or pious lifestyle started to give way to modern day realistic stories and romantic stories. Humor started to gain major attention in the opera stages. The first half of the 19th century saw the peak of the Bel Canto style.

Religion in the U.S. workplace Essay Example | Topics and Well Written Essays - 500 words

Religion in the U.S. workplace - Essay Example This is also designed to reduce the number of cases when people would ask for a religious holiday leave even though no being known as active religious practitioners. 2. If there are disputes over the distribution of the religious holiday leaves, they should be resolved in the following manner. The priority will be given to a person who applied for a leave first, i.e. First come first served rule. Secondly, a person who is known to perform active religious practice before has the priority over a person who has just taken up it. The communication in these cases should be polite and tolerant, trying not to hurt any person or cast any kind of shadow on the religious feeling of an individual. 3. One of the most effective ways to communicate the policy to the employees would be to call for a meeting and present them with a printed out version of the main provision. It is particularly important that they have those printed out as the employees will be able to refer to them any time when they have question about the distribution of religious holiday leaves. Another point about communication is that it should promote the feeling of justice: since the matter in question is rather difficult to regulate, the employees should agree on at least some kind of rule that might be suitable for that. 2. Personally, I do not think that it is a good idea to protect the individuals who are obese in case it is not conditioned by an illness. It is true that managing one’s weight might be incredible difficult, but still it is possible. If a company gives certain preference for obese people, others who are different in someway might raise a question why obesity is taking into account and other abnormalities are not. In addition to that, fair treatment of the obese people might be viewed as an additional stimulus for them. 3. The Weight law involves many issues, such as an effective way to determine the presence of obesity; the grounds upon which

A central assumption made in Mean-Variance Analysis and the Capital Essay

A central assumption made in Mean-Variance Analysis and the Capital Asset Pricing Model (CAPM) is that investors prefer to invest in the most efficient portfolios available - Essay Example To determine an efficient portfolio, an efficient frontier is drawn. The efficient frontier is a graph drawn to exhibit different portfolios with a different combination of returns and risks. To achieve such optimal portfolio, there must be a combination of the lowest risk with the highest expected return. The figure below shows the efficient frontier. The efficient frontier has a Y- axis that measures the anticipated rate of return (ER) and X- axis that measures the standard deviation (∞). The curve JKL drawn in the graph is the minimum variance frontier which combines the risk of a portfolio and anticipated return on portfolio to minimize the return deviation at distinct levels of return expected. On the efficient frontier, there are some points that are found either below or above it. Those portfolios that lie below the frontier provide an inadequate return for a given risk hence they are sub-optimal. In other words, they are attainable but insufficient. Conversely, those that lie to the right of the frontier have higher risks given a certain rate of return. In theinvestment of securities, the main objective is to earn returns from a respective investment. High-risk with high returns is always avoided because they require high capital for investment. An investor can anticipate earning a lot from a given security but because of the fluctuations of the market prices and inflation, such investor can incur a loss simply because the future movements of the portfolio cannot be predicted (Fama 2009, p.452). Given an axiom that all investors fear risk, none of them will be willing to invest in a portfolio that has a high possibility of a loss. However, investors prefer a portfolio that has low-risk because they can be certain of the expected returns from a certain portfolio. Though they will not be getting the maximum returns they wish, they are able to get the returns for unforeseen future because

Capital and unskilled labor are substitutes Essay

Capital and unskilled labor are substitutes - Essay Example These are the factors that facilitate the growth development and expansion of a business. One would therefore have to understand the importance of labor in maintaining the production of more capital for a business. There is an immense similarity between the capital invested in a project and the type of labor it can afford to hire. This is also determined by the materials used by the business as it grows and ensuring that it rises. Production takes place when all the integral parts of an organization or business work together to attain a goal that will contribute to the whole company as well. It is particularly through these social relations to each other that that each part influences the other (Krusell 2000). These interactions between the manufacturers and the atmosphere within which they trade tasks and contribute to the complete construction usually differ depending on the nature of the method of production. Capital also involves the exchange values. It is hence a computation of property, trade ethics and social extent. It maintains its value regardless of the form in which it is invested in. Basically; capital always has a constant value of exchange. For instance, if the capital is in the form of land the exchange value will still remain the same. The commodity may appreciate or depreciate in value but during transformation its exchange value will not be altered. This shows that all factors are interrelated in one way or another so as to produce an end result that favors each integral part of the system (Johnson 1997). A laborer will receive a mode of survival in return for his services. Substitution of capital with unskilled labor would depend on how much initial capital was invested. Low capital investment would not enable employment of skilled labor as this would reflect unrealistic allocation of finances. Therefore, low capital investments will lead to employment of unskilled labor. A workforce that does not have adequate skills would
