The Success of Dell Computers essays

The Success of Dell Computers essays Dell computers are one of the leaders within the computer hardware industry. Started in the late 1980s, it was viewed as a small player within the market by powerhouses such as IBM until its proven sales strategy and production mechanism vaulted it to the top of the industry. A careful analysis of its marketing mix will show how it has effectively positioned itself in the market to succeed on a fundamental level. First, an analysis of Dells overall company strategy and its marketing mix in terms of corporate strategy will take place. Then a further detailed analysis of one of its most successful Desktop PC models will be examined, the Dimension Desktop series. Finally we will examine another line of Dell PCs that have not faired very well in its particular sector, their XPS notebook series. Through a careful analysis of the marketing mix, we will be able to identify both the strengths and weaknesses of the Dell product line and corporate strategy. As an overall company, Dells primary strength is reliant on its strong supply chain and pricing. Price therefore is the key to their marketing mix because its both their strongest offering and their branding niche. Dell is known for top of the line desktops at affordable prices. The price not only is directed to their overall products but also to their customer service, warranty policies and other amenities. The bottom line is that Dell maneuvered itself into creating great value at an affordable price. The second key to the marketing mix, product, is a much more ambiguous area for Dell. The reason for this is that there are many higher-grade products on the market within the desktop industry than Dell products. However, it is because they provide respectable quality products at a very reasonable price that it can get away with not being the leader within the industry on product quality. Its overall promotional strategy is very much d...

Waiting with Bated Breath

Waiting with Bated Breath Waiting with Bated Breath Waiting with Bated Breath By Maeve Maddox I laughed when I read the following in a film review: Richard M. Nixon granted British playboy presenter turned journalist David Frost a series of twelve television interviews. This was the first time Nixon had spoken since his resignation in the midst of the Watergate scandal and Americans waited with baited breath, longing for the trial they’d been denied by newly president Gerald Ford’s blanket pardon. What, I wondered, did those Americans use for bait on their breath? I’m no longer laughing. Apparently a lot of people don’t know that the word is spelled bated in the expression bated breath. Journalists tend to spell it correctly: China’s three astronauts are preparing for the nations first ever space walk as the country waited with bated breath to see if the manoeuvre, deemed highly risky, would be successful. With global automotive CEOs and leaders like Mr Carlos Ghosn saying that his company too would like to explore the possibility of manufacturing a similar car, the world’s media too has been waiting with bated breath for the Tata ultra-low cost car. Shoppers waited with bated breath in November to see what the future of Santas beady, winking eye was after he received a makeover. Many bloggers, on the other hand, tend to go with â€Å"baited† We waited with baited breath, turned our lonely eyes 2 U It was now Rome who waited with baited breath for the day when an army would sweep down.. â€Å"I was waiting with baited breath until I could order my prints. I was then waiting with baited breath until the order was confirmed. I then waited with baited breath until they arrived here in Melbourne, Australia. Now I am waiting with baited breath until they are back from the framing shop and I can hang all three in my house and gaze at them adoringly each time I pass them. The expression bated breath is another that we owe to Shakespeare: Shall I bend low and in a bondmans key, With bated breath and whispering humbleness, Say this; Fair sir, you spit on me on Wednesday last; You spurnd me such a day; another time You calld me dog; and for these courtesies Ill lend you thus much moneys? Shylock is speaking, with heavy sarcasm, to Antonio in the Merchant of Venice (I,iii). A bondman is a slave or an indentured servant who could be expected to speak in a quiet voice to his masters and betters. The bated in the expression is from a shortening of the verb abate and, in the form bate, means â€Å"to reduce, to lessen in intensity.† The expression under discussion is the only survival of the word in modern English. The person who â€Å"speaks with bated breath† is not using full lung power. The person who â€Å"waits with bated breath† is holding his breath, or barely breathing. Abate comes from Old French abattre, â€Å"to beat down, cast down. from a Latin origin meaning â€Å"to beat.† The word abattoir, a place where cattle are slaughtered, derives from the same source. In modern usage, abate is used most frequently in a legal context. For example, â€Å"noise abatement laws† seek to control sources of excessive noise. The noun bait, food put on a hook or trap to lure prey,† is from an Old Norse word. As a verb it means â€Å"to put food on a hook or in a trap.† And yes, there is one context in which â€Å"baited breath† would be correct: Cruel Clever Cat Sally, having swallowed cheese, Directs down holes the scented breeze, Enticing thus with baited breath Nice mice to an untimely death. Geoffrey Taylor, Argosy 1940 Otherwise, it’s bated breath. Want to improve your English in five minutes a day? Get a subscription and start receiving our writing tips and exercises daily!

Analyzing Visual Texts Essay Example | Topics and Well Written Essays - 1000 words

Analyzing Visual Texts - Essay Example The portrait pictures a ship which seemed to have been wrecked on a beach with a few sailors seemingly having escaped the doomed ship. This portrait also portrays the sailors in a boat on sandy cove with the entrance of a dark cave mouth just behind the sailors in the boat. The most striking thing about this picture is the sailors who seem to be struggling with violent waves near a beach with the silhouette of a wrecked ship in the distance. The centrality of the light tower in the painting is of utmost importance as it offers a different perspective to the picture. This portrait portrays the message of the lack of understanding of the forces of nature and the struggle between man and these forces. Discussion The most important element that the author intends to convey is with regard to the characters in the portrait that are a representation of the people of the 18th century. It has to be noted that this was a time when marine disasters and accidents were a common occurrence which c aptured the popular imagination. The characters are drawn in bright colors in order to distinguish them and make them stand out from the rest of the portrait elements. The characters are portrayed at the very edge and bottom of the portrait to put forth the message of the omnipotence of nature and how little power man had over nature. This is in contrast to the forces of nature such as the clouds and waves which are portrayed in bold and angry strokes to show their power. The characters being relegated to a role in the bottom of the portrait yet being in the foreground enables the author to focus attention on the characters but more on the powers of nature as shown by the centrality of the great white waves threatening the sailors. The portrait takes advantage of the attitudes of the times in whipping up emotions and taking advantage of the lack of understanding of nature by the audience. The audience of this portrait live in a period in which very little is understood of nature. Na ture is perceived as being omnipotent and all powerful. A great surging white wave is pictured bending and breaking in the middle of the portrait in what may be perceived as portrayal of the power of nature. The picture is intended to show the great power of nature over man. The men in the picture seem to be in a losing struggle to save their lives. Through the centrality of the great white wave which threatens to wash them out to sea, the author intends to show the futility of man trying to struggle with nature. Nature seems to have won by taking some few lives as can be seen from the vague outlines of bodies floating on the water near the boat. It would seem that the breaking and bending of the wave near the shipwrecked sailors, is an assertion that nature is supreme. Nature seems to be asserting its dominance and demanding respect from the sailors. The sailor who is depicted as holding his hands over his head in a gesture of prayer offers an even more profound understanding of ho w religion was used in understanding nature. Religion is an important element which the author intends to put into use in explaining the audience’s attitudes towards nature. Due to little knowledge on science and how to interpret the weather and other forces of nature scientifically, religion was the main way through which these people tried to understand natural phenomenon. The author in picturing a sailor in a posture of appeal to the

Are cell phones really dangerous to people Essay

Are cell phones really dangerous to people - Essay Example Are cell phones really dangerous to people? The control of the advertising of cell phones would be another important measure for preventing the extended exposure of people to the cell phones’ radiation. Cell phones should be regarded, as tools of communication and their use should be limited in cases of emergency. Otherwise, the increase of fatal incidents and diseases because of cell phones would not be controlled. Moreover, the terms under which the access to cell phones has been permitted to teenagers have been reviewed – taking into consideration the fact that people of this age are less likely to pay attention at the risks related to the use of cell phones – as highlighted in relevant academic studies. At this point, the following problem has been identified: children have often access to cell phones with the permission of their parents. This trend is extremely dangerous especially since scientists have set severe restrictions regarding the potential use of cell phones by children – but these restrictions seem to be ignored by most of people worldwide. At this point the following problem appears: are cell phones really dangerous to people? This problem has been explored through a series of relevant studies. It is proved that cell phones can actually harm the health; moreover, it seems that the risks for health can be severe for people of all ages. At the next level, it has been made clear that the ways in which cell phones can affect the health of humans can vary; the direct use of cell phone may be less harmful compared to the residence near a cell phone tower. In the article of Geoffrey, published online by the Independent, reference is made to the research of Dr Vini Khurana who studied the effects of cell phones on health; the above research led to the following findings: ‘the use of handsets for 10 years or more can double the risk of brain cancer’ (Geoffrey par.3). In the above study, emphasis is also given on the fact that certain types of cancer can take quite long to develop – even up to a decade; therefore, the above study – having lasted for such period - provides a precise estimation of the potential effects of cell phones on brain. Another important finding of the study of Khurana has been the following one: cell phones can be more dangerous from smoking (par.1); the above finding indicates the level of risk related to the use of cell phones but also the level at which cell phones intervene in daily activities having led to the development of addiction similar to smoking – as this problem is revealed through the study presented above. The various aspects of the danger of cell phones for human health are analyzed in the article of Kovach, published online by the magazine Life Extension; in the above article reference is made to the findings of the research developed by George Carlo, a medical scientist who has spent years on studying the effects of cell phones – both of handsets and cell phone towers – on health; his research lasted from 1993 up to 1999 and reveals a series of important aspects of the health risks related to the use of cell phones (par.3, 4). The key findings of his study could be summarized as follows: a) cell phones are not tested as for their risks for health; they enter the market without any testing, as a result of a legislative gap of the peri od when these devices appeared – the 1980s (par.5), b) cell phones can cause severe problems of health, even death, since they are involved in the continuous transmission of waves which can adversely affect the bio-field of humans (par.6); it is possible for this reason that cell phones have been also related to the changes in the DNA of their users –

Drug Testing Welfare Recipients -- Article Analysis Essay Example for Free

Drug Testing Welfare Recipients Article Analysis Essay Jonathon Walters author of â€Å"Should Welfare Recipients be Drug Tested?† published an article on March 13, 2012 for Governing: The State and Localities that provided readers with several points of interest when discussing drug testing welfare recipients. Walters states in his article â€Å"According to the National Conference of State Legislatures, almost two dozen states are considering bills that require drug testing those either applying for or receiving public benefits, a policy that has been cut down in the courts before because the Fourth Amendment grants that every individual be secure in their persons, houses, papers and effects against unreasonable searches and seizures. (Should Welfare Recipients be Drug Tested? para 1.) This paragraph explains that states are having difficulty passing this bill because the government feels that it violates American’s 4th amendment. Walters brings up arguments from both a favoring side and an opposing side. Favoring sides would not want to give someone government benefits if they are using the benefits to support a drug habit and could save the government money by denying applicants. The opposing side feels that drug testing would come to a great expense to the government and rather than drug testing an individual who needs help because of their drug addiction other programs such as rehab would save money to local, state and federal governments. The author feels that both are good arguments. To further continue on the opposing side of drug testing welfare recipients; Walters explains that â€Å"Drug testing is expensive. Tests cost anywhere from $35 to $75 to administer, according to the liberal-leaning Center for Law and Public Policy. By their math, it would cost anywhere from $20,000 to $77,000 to catch one drug abuser.† (Should Welfare Recipients be Drug Tested? para. 4). On the favoring side legislators have a different calculation and use evidence that biometric screenings such as finger printing lower numbers of participation among welfare recipients. States that do not participate in finger printing have more people applying for welfare. Walters feels that this would be a â€Å"cynical† way of lowering costs. Opposing sides also feel by isolating those who are at risk, for example ex-felons may lead them down a wrong path again because applying for welfare is much harder, therefore, costing the government more money by putting them back in jail and providing them with treatment. Walters asks how will the government determine who receives welfare and how do we make sure that the wrong person doesn’t receive it? Technology will help determine that mistakes won’t be made. â€Å"The public, in general, supports providing help to those who really need it. In that regard, states and localities are developing much more precise tools mostly thanks to improved information technology to ensure that only those who qualify for benefits receive them (and, not incidentally, to ensure that those providing services arent gaming the system).† (Should Welfare Recipients be Drug Tested? para. 8). Overall, Jonathon Walters remains neutral throughout the article and provides detailed rebuttals for both opposing and favoring sides. He agreed that both sides had good arguments and in the end it would be up to America in the long run to decide what is best for its people. References Walterss, J.

Acid Rain :: essays research papers fc

Acid Rain and its Effects On Our Aquatic Ecosystems In the past century, one of the greatest threats to North America's aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems, as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain, and what can be done to improve North America's water quality and prevent future catastrophes? To answer these questions, we must first examine the cause and formation of acid rain, as well as understand ways to decrease or prevent its formation. Formation of acid rain. Acid deposition, more commonly known as acid rain, occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water, oxygen, and oxidants to form acidic compounds. This mixture forms a mild solution of sulfuric and nitric acid which then falls to the earth in either wet (rain, snow, sleet or fog) or dry (gas and particles) form. Approximately one-half of the atmosphere's acidity falls back to earth through dry deposition in the form of particles and gases, and are then spread hundreds of miles by winds where they settle on surfaces of buildings, cars, homes, and trees. When acid rain falls, the dry deposited gases and particles are sometimes washed from buildings, trees and other surfaces making the runoff water combine with the acid rain more acidic than the falling acid rain alone. This new combination is referred to as acid deposition. The runoff water is then transported by strong prevailing winds and public sewer systems into lakes and s treams. Although some natural sources such as volcanic eruptions, fire and lightening contribute to the emissions of sulfur dioxide and nitrogen oxides in the atmosphere, more than 90% is the result of human activities such as coal burning, smelting of metals such as zinc, nickel and copper, and the burning of oil, coal and gas in power plants and automobiles. When does rain become acidic? Scientists determine whether rain or lake water is acidic by measuring its pH (the measure of acidity or alkalinity of a solution on a scale of 0 to 14). A value of 7 is considered neutral, whereas values less than 7 are acidic and values over 7 are alkaline or basic. A change of one unit on the pH scale represents a factor of ten in acidity; for example, a solution with a pH of five is ten times as acid as one with a pH of six .
