Free Essays on Living in a Lifeboat

In his 1974 paper titled â€Å"Living on a Lifeboat†, Garrett Hardin reduces growing populations and immigration to a metaphor of living in a lifeboat. The premise of the paper is that each country is like a lifeboat, only capable of handling a certain number of people. Once that capacity is reached, there runs a risk of upsetting the balance, and overturning the lifeboat, or society. If the lifeboat is already at capacity, then no more can be let on the boat, as well as no more can be born on the boat, until there occurs a death, creating a space for someone new. The United States is a lifeboat, and there are many people foundering in the ocean, wanting a chance to board our lifeboat, since it would yield a good, fruitful life. However, admitting many people would be detrimental to the health and success of the lifeboat. Of course, with this idea, there arises many ethical and moral issues, along with the practical. These can be looked at through many viewpoints, but t he most favorable one is the viewpoint of oneself, and your own survival. Since Hardin proposes that the United States lifeboat only give wisdom, not food, to other foundering lifeboats, we could incorporate the idea of one Jonathan Swift, and pass this wisdom onto other lifeboats, thus increasing their chances at survival. Hardin first observes that the people residing in the lifeboat could take a Christian or Marxist viewpoint of the whole matter. That is, try to help all of the people who are looking to join your lifeboat. If this were to occur, the occupancy of the lifeboat would soon far exceed the capacity of it, and it would sink, killing all aboard, including oneself. His second observation is that there is a limited number of empty spaces aboard the lifeboat. Thus a small number of people can be admitted to your lifeboat.

CORREGIDORA essays

CORREGIDORA essays Gayl Jones's Corregidora is not your typical response to a long and rather terrifying history of slavery in the Americas. Instead, it is an attempt to humanize the ugly experiences of older African-American generations. While on the surface, it appears another story focusing on the history of slavery in Americas; it is nonetheless a deeper and more complex analysis of that period in time. Ursa, is the protagonist of the novel, who is burdened by the painful history of her family and believes she is responsible for passing the stories on to the next generation, the way her mother and grandmother did. However since she has not experienced slavery in the way her ancestors did, Ursa relives those experiences through her music. For Ursa, music is her savior. She believes it can help her find the liberation from past that she seeks so ardently. However because of the fact that her ancestors including her mother and grandmother, constantly remind her of their past, Ursa is perpetually haunted by her family history. Music is important to her as she says in the novel, "I am Ursa Corregidora. I have tears for eyes. I was made to touch my past at an early age ... Let no one pollute my music. I will dig out their trumpets. I will pluck out their eyes" (77). Music is her sole means of redemption because in the absence of authentic records, Ursa felt her blues could the pain and suffering of her ancestors to next generations. Corregidora has both real and symbolic value in the book because on the one hand he is the person who destroyed the lives of Gram and Great Gram while on the other, he also symbolizes male legacy of chauvinism and exploitation that threatens the female freedom and existence. In the novel, Ursa is so intricately connected with her family history thatr everything that happens to her is linked with some past ugly experience of her ancestors. For example, when she becomes infertile ...

Capital Projects Recommendation 2 Assignment Example | Topics and Well Written Essays - 250 words

Capital Projects Recommendation 2 - Assignment Example Operating cash flows includes; sales revenue, cost of production, income before taxes, marginal tax rate, depreciation, increase in working capital. Terminal cash flow includes; decrease in working capital, salvage value, marginal income tax rate. Cost of capital evaluates the cost of borrowing to pay for the project. This value is set as the benchmark for the lowest possible return. Opportunity cost determines the cost for taking advantage of one option over another. Break-even point determines if the project would contribute to the growth of the company. Capital budgeting technique uses different formulas for analysis of financial values to determine if a company should proceed with the planned investment or not. These formulas contain various parameters, and they have specific concepts. These parameters are Net Present Value (NPV), Internal Rate of Return (IRR), and Payback method. Embedded concepts of these parameters helped me evaluating fully equipped facility cost. Capital budgeting technique requires calculating OCF. All three parameters; NPV, IRR, and Payback use OCF values. NPV evaluates present value of the future cash flows that the project generates during its life (â€Å"What is NPV†). In simple language if the value of money generated during the project life is higher that the initial investment, the project makes money. IRR determines (Mohr) the cost of return at which all cash inflows (revenues) equals the present value of cash outflows (initial investment plus any other expenses). In other way, it is the cost of capital at which NPV is zero. Hence, if IRR is higher than the cost of capital, the project is making money. Payback period calculates the length of the time it will take to get back company’s initial investment. In other words, this method defines how long would it take to get the investment money back. Theses three parameters tell me; (1) how long would it take to get the initial investment back, (2) how much money the

Things Fall Apart Essay Example | Topics and Well Written Essays - 1000 words - 1

Things Fall Apart - Essay Example The fact that he has three wives in and of itself illustrates his misogynistic nature and attitude. He is terribly cruel to his son Nwoye, as he feels that Nwoye is not masculine enough and that he is feminine and weak. Nwoye begins to behave in more masculine ways to please his father Okonkwo, as anything less is simply unacceptable and can lead to a beating from his father. Okonkwo is a portrait of dominant male ideology as he causes his family a great deal of pain and suffering because of this ideology. Okonkwo is rarely able to display emotion and is depicted as first and foremost, seeking to be masculine and in control. He is depicted however, at one point in the story, as a concerned parent, when he ventures out looking for Ezinma, after she is taken by Chielo. The reader also sees throughout the piece, Okonkwo’s difficulty in dealing with change in his environment, especially from a racial point of view. White men are coming to his village and living among his clan, only to cause Okonkwo to feel threatened and then to finally feel defeated. This is understandable as the white settlers only seek to change the ways and beliefs of the natives of Nigeria. These expressions of anti-colonialism seem to reflect the ideas of Achebe as well, as a prevailing theme surrounding the colonists seems to be their inability to speak the language of the tribe. This is ultimately what prevents them from understanding the ways of the tribe. Interestingly, as much as Okonkwo opposes the whit e man and his religion (Christianity), his son Nwoye converts to this very religion. Certainly, this is an illustration on the conflicts that arose during colonization. The white men brought their religion and beliefs to the Igbo people, and certainly Okonkwo represented the institution of tradition and culture. Further evidence of this is the fact that Okonkwo participates in the death of Ikemefuna, the sacrificial boy from a neighboring village

Our Daily Bread Essay Example for Free

Our Daily Bread Essay Our Daily Bread, as the title suggests this is not about bread, as I hoped it was. Rather its about people earning their bread, their livelihood. The term ‘bread’ is derived from the larger term ‘bread-winner’ as the one who is the primary provider of the household, and the ‘daily bread’ is simply referring their daily livelihood. As my time spent in the US, I often used to wonder how the different food companies were able to produce mass amount of food to keep the population fed. This movie is the answer and the revelation of how food is produced in Europe and the Western hemisphere. The film starts off as we get a glimpse of daily sanitation rituals being carried off at a meat farm. The different scenes show us to transportation of livestock, machine assisted watering of plants, and a conveyor belt at a poultry farm where they separate the males from the female chickens (I know this as I have seen this done before in a different setting). The machinery at poultry farm shows precision and efficiency as it sorts the young chicks into moving bins. The vaccination routine is also machine assisted which increases efficiency and production for the poultry farm. After few seconds, the young chicks have grown and we are shown the worker feeding them. The shot transitions into a break room where the worker is on a break with bread and tea, all alone. Next, we get the scene from a vegetable farm. A tractor picks the potatoes from the ground. Next shot, the workers prepare and wear protective gears to apply pesticides and fertilizers to the plants. But most of the work is done by machine assistance, needing almost no human intervention. It seems as the vegetables are being grown inside a greenhouse setting which allows vegetables to be grown all year long, without any weather restrictions. The only human labour being done is picking of the ripened vegetables. After work, the worker seem to be enjoying a small break, again alone. Now we see a bull and a cow where it seems breeding is in process. A closer look and we find that the workers are actually collecting the sperm. We find the sperm is transferred to medical examinations, I dont know exact ly why but possibility could be to efficiently use the sperms to fertilize every fertile egg they can afford without any loss. And of course, we see a healthy calf being born. But it is pretty amusing to see how the cow was cut open and the calf was pulled out, how could that really be possible? How much medication could the animal be on since it wasn’t moving or making any noise as such? And are there any advantages of this type of birth for animal? Next, we see a series of shots of men in tractors who are doing farm work with machine assistance. This shows the efficiency that is earned by machine which helps humans achieve more with less time spent and more time to spend on luxury, or more work. We return back to the poultry farm, the egg farming room to be exact. The eggs are hatched and due to the design, they are conveniently accessible by the farmers to pick. A worker is shown to be holding a chicken as he walks around the egg farm, possibly to warn other hens who dont lay eggs. In actual note, he maybe was checking for chickens which are dead. In the next shot, the workers are transported to a huge plantation to harvest crops growing under the ground, only time where tractors arent used. This is possibly the first time where machine use is limited to just watering the plants. Now we are shown our way to a pig farm. They are transported on a line into a machine where they are slaughtered by a machine. The human labour is limited to keep the line moving and in order. The machines are also used for most of the heavy work as boiling the skin and dissecting the pigs open. The human job is limited to cleaning up whatever else the machines may have left out and separating internal parts. We are also shown the marvel of modern technology with a biplane is used to fertilize the crops. There are also shots of heavy machinery usage in farms. Then we see a moving harvest truck where the outside workers are picking the vegetables and inside simply packaging them. Now we move to a cow-ranch. The cows are milked by machines in a rotating carousel. The cows dont seem to mind so much, as it seems to be part of their daily routine. Next, a visit to the deep underground salt mines where machines are used to do most of the heavy work such as carrying out the salt from place to place and outside the mine itself. A transition moves from underground to underwater as we see a fish-farm where hundreds and hundreds of fishes are seen in a small area. This also makes it easier for the huge pipe to suck out the fishes from the water and into the boat. They are transported to a factory where humans align the fishes to feed into the machines. Apparently the machines havent learned to distinguish the fish head from the tail, yet. The fishes are cut and cleaned by series of machines and then moved onto another human where he puts them on another machine to move them to another section. Here, the worker seems pretty bored of the routine task he has, perhaps feel ing like the machine at this point because of his job task. Next we see bunch of workers cleaning the fish for final prep before shipping them out. Now we come to a pig-farm. The two series of shots seems interesting as the first represented insemination of pigs by tube and next shows the piglets born in captivity, just like ‘The Matrix’. Just like in the movies, they grow up and the next shot seems as if the male pigs were being castrated. One can only understand why so, as they dont want to overproduce and give out the employees any bonuses. Or maybe not. The next series of shots show how chicken and cattle are prepared for consumption; as they are killed by the machines with little or less human effort required in the process. The final shot shows the end of the day routine- how everything is cleaned and sanitized for the next day of work. Despite all this, the workers in all places couldnt wait for their daily bread, their hard earned break from their work. Perhaps the routine manner of their tasks has become so innate to them that they dont seem to mind how their own food is being produced. For me, it was a bit amusing and shocking to see the conditions of animals but maybe after a few more views, I wouldnt mind it either. This movie shows the heavy usage of machinery used in the production of food, be it salt, pigs, chicken, vegetables, fish, or pigs. It was also amusing, in a way, to see how breeding had gone into the next level by scientific usage to effectively get their result financially and also in economic ways to feed the ever growing world population. It seemed as almost if humans were not the only ones alienated from nature, but also the animals which were being artificially inseminated and mutilated against their wills. The workers didn’t seem to care much for what they were doing either, as long as it made their breads. It seemed as they had been trained to do this for so long that they were used to it- like machines with machine hearts and machine minds. In another view, the unnatural size of the bulls in the breeding house seemed as if they were so-much genetically engineered to produce the maximum amount of meat possible. Perhaps they had mixed something in the dry grass that was being blown into their small cages they were put-in. The growing population also has seemed to affect the unnatural process by which plants were grown with usages of pesticides and fertilizers. The use of greenhouses portrays, in a way, the plant’s alienation from nature as it was now possible to grow all plants in any weather or conditions. The absence of narration or subtitles leaves the movie-watcher to make their own conclusion and perspective. The filmmaker, as I understand, doesn’t want to change our habits but simply be aware of the ways in how the planet is being fed. If anything, this should be seen by as many people as possible to make them aware of the status of food production and the status of the subjects which are involved in the food production i.e. humans, plants and animals alike. I must say some of the scenes in the movie are quiet disturbing but that is the current status of our population and food production required to feed them.

Internet Access Essay -- Internet Web Cybespace Essays

Internet Access   Ã‚  Ã‚  Ã‚  Ã‚  It would be helpful to provide a brief historical summary of the Internet before jumping into the different means of accessing "The Net".   Ã‚  Ã‚  Ã‚  Ã‚  The Internet was developed primarily by Vinton Cerf, an American computer scientist, in 1973 as a part of a United States Department of Defense Advanced Research Projects Agency project managed by American Engineer, Robert Kahn. In 1984, the project was turned over to the private sector and to government research and scientific agencies for further development. In 1993, the Internet was turned over to the public and by early 1995 access was available in over 180 countries and there were over 30 million users. It is expected that 100 million computers will be connected to the public Internet by the year 2000.   Ã‚  Ã‚  Ã‚  Ã‚  The public Internet can be accessed in several different ways: through a LAN, by a host, terminal access or gateway access. A LAN is a Local Access Network where there are a group of computers and other devices that are spread over a relatively limited area and connected by a communications link. This also allows you to communicate with any other computer on the network. If you access by a host, it is usually done through a LAN or with telephone lines and modems combined with Internet software on a personal computer. Terminal access is usually done by a telephone line and a modem and it is used with terminal- emulation software on a personal computer. This also allows you to int...

Country Side

Country Side Freedom surrounds those who aspire to achieve lonesome from the rest of the world. The perfect getaway is something that most people deserve once in a while. Complete solitary from everything and everyone nothing but fields for miles and miles away. The country side has a lot to offer the spectacular view and stunning landscape. It doesn’t matter whether it is winter, spring, fall or summer because either of these seasons changes the fact of how admiring the view is from a far. I am a victim of this ignorance. I never realize how precious and beautiful the country side is until I saw Harvey George W. ainting, New England Landscape, at the Andersons Gallery in Beverly Hills that opens my eyes into larger sense of beauty and strength. Harvey George W. was known for his Techniques of Fly Tying Fishing. Harvey was born on November 14, 1911, in Dubois, Pennsylvania. His father Archibald accepted a job as a stock farmer in Lansdale, Pennsylvania. That’s where he got inspired by painting the New England from his childhood memories. While Harvey was in the farm he had learned so many things and to appreciate what was handed to him, he did not come from a wealthy income family and all he could have done is go by what his expectation were.His Father Archibald teaches him how fish by the stream right off the stream. Even more he was being afflatus by the nature that surrounded him. Harvey is not a well-known artist but more for his achievements at Penn State University. At Penn State he teaches Fishing Tying for the first Time in history and that class was accredited in 1947. Also he got offered to run in the Olympics but then he was diagnosed with pneumonia and did not get to compete. In my perspective view, seeing this painting of the country side makes me want to forget about life and go there to escape from the everyday basis.The scenery is breath taking. The tree that is located on the center left hand is perfected it reflects how privacy i s supposed to be like. The stack of hay behind the giant tree is a symbol of freedom. The hay represents how everyone who would like to be stress free can just hide behind a tree and forget about their existence. The farm town is far away like it’s supposed to be and endless fields. This portrait reminds me of my own family ranch in Mexico; it made me realize that I am taking that part of my life for granted.

Thermoelectric generator

Plantation for providing the necessary infrastructure out this project successfully. I also thank Dry. S. Maryanne, Dean, School of Mechanical & Building Sciences for his support and continuously encouragement in completing the project. I express my genuine indebtedness to Mr.. C. Rammers Kumar, Senior Assai. Lecturer, School of Mechanical & Building Sciences whose whole hearted guidance and valuable suggestions throughout this project helped us in completing it successfully, without which the project would not have attained a fine and final shape.I would also like to express our gratitude to all faculty members of the school for their timely encouragement and thought provoking suggestion to pursue our work. Last but not he least, we would like to thank all those who were directly and indirectly helped us in completion of this project. CHAPTER: I 1. 0 Introduction Man's constant evolution couldn't have been possible without fuels. Society is putting more emphasis on the mobile transp ortation sector to achieve future goals of sustainability and on low thermal efficiencies of ICC engine.About 60% of heat-energy liberated during combustion of fuel is not utilized in producing useful work and getting dumped into the atmosphere daily. To achieve these goals, society needs to jump to a new method to recover the lost part of exhaust energy. The recovering of heat from exhaust gases in automobiles is a typical area of generating steam (or) electricity using W. H. R. B. * (or) Thermoelectric. It depends on the basic principle of ‘Speck Effect'.It would be useful to demonstrate the potential of thermoelectric generation in the automobile industry using Thermoelectric Generator (Tee's). A thermoelectric generator, which can be driven by the temperature difference, incorporates fins into a thermopile to conduct heat toward or away from the alternating spaces between adjacent layers of different types of thermoelectric material. Vehicles are becoming more electrified and the higher electrical demands under nearly all driving conditions are required.On board electrical energy management and storage systems are more prevalent. TEE'S provides source of additional electrical power without increasing fuel consumption. The study reveals that about 6% of the exhaust energy can be taped from the exhaust there by increasing the thermal efficiency. It can be used to increase the overall efficiency of the engine without increasing the fuel consumption and thus there would be a separate source of the electricity that a vehicle needs for keeping its battery charged and for erring all of its on-board electric circuits. W. H. R. B. = Waste heat recovery boiler 1. 1 Problem Specification To design and fabricate the Thermo Electric Generator and its various components. To test the TAG under various conditions when used on Marti 800 standing engine. 1. 2 Objective To design the TAG and its various components using Silkworms (CAD) designing software and to fabrica te the same using various manufacturing processes. Then the manufactured model is tested for efficiency , power output under various conditions when tested with Marti 800 standing engine.CHAPTER: II 2 Literature Survey 2. 1 Thermoelectric Principle The Thermoelectric principle though established for long back found application only to the field of sensor industry. But recent advances in materials, especially in semi conductors have paved way for applications to the field of power generation. This project studies the application of Thermo electrics as a waste heat recovery solution in vehicles and their potential for the future. 2. 2 Speck Effect The Speck effect is the conversion of temperature differences directly into electricity.This effect was first discovered, accidentally, by the German-Estonian physicist Thomas Johann Speck in 1821 . He found that a voltage existed between wow ends of a metal bar when a temperature difference AT existed in the bar. Fig. 1. 3 – Speck ef fect AS and SUB are the Speck coefficients of the metals A and B, and TTL and TO are the temperatures of the two Junctions. The Speck coefficients are non-linear, and depend on the conductors' absolute temperature, material, and molecular structure.If the Speck coefficients are effectively constant for the measured temperature range, the above formula can be approximated as: Thus, a thermocouple works by measuring the difference in potential caused by the dissimilar wires. It can be used to measure a temperature difference directly, or to assure an absolute temperature, by setting one end to a known temperature. Several thermocouples in series are called a thermopile. This is also the principle at work behind thermal diodes and thermoelectric generators (such as radioisotope thermoelectric generators or Arts) which are used for creating power from heat differentials. . 3 Semiconductor Based Thermoelectric Though the thermo-electric principle was established in the early 19th century , it was only after mid-20th Century advancements in semiconductor technology, however, that practical applications for thermoelectric devices became feasible. Semi- inducting materials, (in conjunction with copper inter-connecting pads), have been found to offer the best combination of Speck coefficient, electrical resistively, and thermal conductivity.Semi-conducting materials provide another benefit, the ability to use electrons or â€Å"holes† (the absence of an electron in a crystal matrix) to conduct current. This last property is useful in assembling many thermoelectric Junctions in series to reduce the overall current flow in the device to manageable levels. 2. 4 Thermoelectric Modules (TEEMS) Bismuth Telluride-based thermoelectric modules are designed primarily for cooling r combined cooling and heating applications where electrical power creates a temperature difference across the module.By using the modules â€Å"in reverse,† however, whereby a temperature d ifferential is applied across the faces of the module, it is possible to generate electrical power. Although power output and generation efficiency are presently low, useful power often may be obtained where a source of heat is available. 2. 5 Teems for Power Generation Thermoelectric (ET) energy conversion for power generation is based on the â€Å"Speck effect†, where a temperature difference, TTS-TTS, across two dissimilar legs of nonconductor material produces a voltage, Avocado.This voltage is equal to the Speck coefficient of the material, a, times the temperature difference across the device. The dissimilar legs of semiconductor material, one p-type and one n-type, are called a thermoelectric couple. The p- and n-legs are Joined by an electrically conducting material at the p-n Junction. A thermoelectric module consists of a series of p-n couples, which are connected electrically in series and thermally in parallel. Electrically insulating material separates the electr ical connectors from the heat source and sink.When a temperature gradient is applied across the couple, the negatively charged electrons, e-, in the n-leg and the positively charged holes, h+, in the p-leg move from the heat source to the heat sink, conducting heat to the cold base. This flow of electrons and holes causes separation in an initially uniform charge carrier distribution, which results in a current flow, l, in the couple. A thermoelectric module used for power generation has certain similarities to a conventional thermocouple. With no load, the open circuit voltage as measured between points a and b is: V = a.AT Where: V is the output voltage from the couple (generator) in volts a is the average Speck coefficient in volts/K AT is the temperature difference across the couple in K where When a load is connected to the thermoelectric couple the output voltage (V) drops as a result of internal generator resistance. The current through the load is: ‘load = (a . I is th e generator output current in amperes RCA is the average internal resistance of the thermoelectric couple in ohms the load resistance in ohms The total heat input to the couple (Sq) is: Sq The . L) – (0. 5. 12 . + (KC .CAT) Sq is the heat input in watts Kc is the thermal conductance of the couple in watts/K couple in K 2. 6 Module Selection The is the hot side of the The selection of the appropriate module for power generation with required voltage and current output was done on the basis of literature survey and was found that bismuth telluride module best suited to our condition because of its high efficiency and high operating temperature. Bismuth Telluride module was used because of its easy availability, low cost and low operating temperature range with a considerable efficiency.Material used for fabricating the outer frame is Cast Iron of 5 mm thickness, Cast Iron is used because of its cheap and easy availability. Outer Frame structure made on Solid Works Real time out er frame Full Assembly of the Chamber After the frame was manufactured, it was connected to the main setup as shown low, The setup included the catalytic converter attached to the Marti 800 engine. The inlet to the frame (TAG) is attached to the exit of the catalytic converter and the exit of the frame is to release the final exhaust gas to the atmosphere through a pipe.Here heat energy is converted into electric energy using thermoelectric module and therefore two plates are used in this experimental setup one is hot which is in direct contact with the exhaust gases flowing through the frame on one side and the other side of hot plate modules are placed and the other plate is cold plate which is assembled with cooling chamber as shown below, Hot plate used here is Aluminum of 5 mm thickness, one of which side is connected to frame exposed to exhaust gases directly.The picture below is the hot plate when modules are attached to it with the interface pads in between to increase the t hermal conductivity and to reduce the thermal resistance between the plate and the module. The cold plate which is assembled with cooling chamber is shown below, After connecting all this plates and module the entire frame structure is made to stand connected to the engine as shown above in one of the figure, and below shows he final completed set up with the exhaust pipe connected to the frame.

Causes of Shoreline Erosion

Causes of Shoreline Erosion Free Online Research Papers There are many causes of shoreline erosion. Most of them are natural. These are currents, storms, earthquakes, winds, waves, tides, and also the gradual movement of tectonic plates. Some beaches are also destroyed by men when harbors and dams are built, or any other structures that disrupt the fragile balance of nature. There are several different ways that the ocean can cause erosion: hydraulic action, wave pounding, abrasion, corrosion, and attrition. Hydraulic action takes place when air in a joint is suddenly compressed by a wave closing the entrance of the joint causing the joint to crack. Wave pounding is when the sheer energy of the wave hitting the cliff or rock breaks pieces off. Abrasion or corrasion is caused by waves launching seaload at the cliff. This is by far the most rapid form of shoreline erosion . Corrosion is the dissolving of rock by carbonic acid in sea water. Limestone cliffs are the most vulnerable to this kind of erosion. Finally, attrition is where particles carried by the waves are worn down as they hit each other and the cliffs. This then makes the material easier to wash away. Sediment is transported along the coast in the direction of the current. When the incoming current amount of sediment is less than the amount being carried away, erosion occurs. According to the Army Corps of Engineers, the most important cause of humans include the disruption of sediment sources with seawalls, revetments, and bulkheads, and the interruption of longshore sediment transport by the construction of groins and jetties.

Prima Donna

Prima Donna Prima Donna Prima Donna By Maeve Maddox Henry Preston writes: Please, please, help nip this malapropism in the bud: Pre-Madonna. Im not kidding, Ive seen this twice in the past few weeks on comment boards. prima donna [prÄ“mÉ™ dÃ… nÉ™] (pree muh don uh) is an Italian term translated literally as first lady. In the music world, a prima donna is the best and most celebrated female singer in an opera company. Maria Callas swept into New York. She arrived, as is proper for prima donnas, in triumph. [Carmen] Melis had been a soprano prima donna at La Scala in Milan and had sung with Caruso and Titta Ruffo. Often referred to as the greatest Italian prima donna of the last half century, Tebaldi made her debut as Elena in Boito’s Mefistofele in 1944. Because some prime donne (plural of prime donna) felt that their talent and popularity deserved special treatment, the term came to mean self-centered, arrogant, uncooperative person. In this sense it is used to describe gifted or otherwise significant people who know their worth and want everyone else to kowtow to them because of it. The Senate, meanwhile, is an institution that, by nature, furthers individualistic prima-donna-ism on both sides of the aisle. This is namely for executives: how do you deal with prima donna employees? What is the best approach? Steeles A Prima Donna But We Arent Ready To Kick Him Off Stage One use of pre-Madonna is as a play on words in connection with the pop singer Madonna Louise Veronica Ciccone. When it comes to out-and-out ignorance of the term, the greatest supply of examples is to be found on semi-literate blogs and comment boards, and in sports writing. General comments: you both sound like pree-madonna little girls? arguing over a game, im not trying to get involved in ur war, but how about growing up? im a young egyption princess or milk maid im the greatest pree madonna in the land, I am sick in tired reality show celebs acting like pree-Madonna. Sports-related: Ankela is a little pre-madonna. What an attitude problem. The worst thing of it is that he actually believes that he is far superior to his peers. My trainer calls me a preemadonna cause i like to look good lol. Jay cutler is a primadonna (Not like Alex Rodriguez [was] a pree madonna) Lebron Premadonna James will never win a championship!! Its amusing that a term meaning best female singer has come to be applied to burly athletes. The Italian term for best male singer is primo uomo [prÄ“mÃ…  wÉ”Ë mo]. Bottom line: Unless the context has something to do with the pop music world before singer Ciccone came along, the expression is prima donna. Want to improve your English in five minutes a day?

The Modern World-System Essay Example | Topics and Well Written Essays - 500 words

The Modern World-System - Essay Example Unlike an empire where political structure connects culture with livelihood, the political structure in the world-economy works towards connecting culture with spatial position. Cultural harmonization tends to work in the best interest of specific groups in world-economy. In core-states, integration has perpetuated disparities that exist within the world economy. World-economies are made up of core-states. Peripheral regions are weak and have low independence. Sandwiched between core-states and peripheral areas are semiperipheral areas, which are an essential component of the world-economy structure. Semiperipheral areas act as a link between core-states and peripheral areas. The modern world-economy is a typical capitalist economy. The geographical definition range, as well as the status of its self-consciousness, remains vital in assessing a class. A group self-conscious is an outcome of conflict scenarios. Class boundaries in the upper societal strata are explicit ensuring a high likelihood of maintenance of privileges. There is a single class that has established itself as a universal- capitalist class. There is always friction in the relationship between the capitalist class and all the other social strata. Strong states work in the best interest of a particular group at the expense of others. In the world-economy, structures tend to be strong in core-states, while weak among periphery areas. Exploitation and rejection of coercion still remain an integral part of the modern world economy.

Financial analysis - Case Study Example The report concludes with the summary of the EMI Group's financial performance in 2005. EMI Group PLC is a large company specializing on the music industry. The firm has a long history dating back to 1887. Since that time EMI Group has developed from a small recording enterprise into a major player of both music recording and music publishing markets. It is divided in to two divisions: EMI Music operates in the recording industry, while EMI Music Publishing is among the largest and the most successful music publishers. EMI Group operates directly in more than 50 countries with licensees in additional 20 and employs more than 6,600 people (EMI Group 2005a). EMI Music has about 6,000 employees worldwide, and EMI Music Publishing employs 630 staff. The strategy of the company is to deliver music - the main product of EMI Group - "in any form [including compact discs, tapes, and digital formats], at any time, and any place" (EMI Group 2005a). In line with this formula it is important to stress that EMI Group rapidly develops its departments focused on digital music sales. "By the middle of 2005 digital revenues accounted for just under 5 per cent EMI Group's total revenues, with that figure expected to reach 25 per cent in five years" (EMI Group 2005a). The catalogue of music published by EMI contains over 1.5 million titles of both classic and contemporary genres. The company offers songs of every genre to customers. Profit and Loss Account Profit and loss account of the company provides a record of all revenues and expenditures and totals the profit or loss over a given period of time (in our case the financial year ending March 31, 2005). To analyze the profit and loss account of EMI Group we will look into the following types of profit: gross profit (revenues from sales minus costs of goods sold), net profit (gross profit minus overheads), pre-tax profits (net profit plus one-off items), and profits after tax (pre-tax profits minus tax). The analysis of the profit and loss account is made in order to identify trends in sales, gross profit, expenses, stability of income, and growth in earnings per share. Group turnover for EMI Group is 1,942.8 m in 2005, while in 2004 it was 2,120.7 m (EMI Group Annual Report 2005b, p. 69). However these figures cannot give us enough information about the changes in profitability of the company. Cost of sales indicated in 2005 were 1,225.3 m in compare with 1,404.7 m in 2004 (EMI Group Annual Report 2005b, p. 69). Therefore, EMI Group sold fewer goods in 2005 than in 2004. The gross profit in 2005 was 717.5 m, while in 2004 it was 716 m. This gives us the notion that the profit from sales is slightly rising in compare to previous year. Analyzing the net or operating profits one can see that group net profit was 182.2 m in 2005 and 60.1 m in 2004 (EMI Group Annual Report 2005b, p. 69) - the net profit has risen significantly in 2005. Pre-tax profit aggregates 91.8 m, and profit after tax is 60.6 m in 2005, while it was a loss of 52.8 m and 72.5 m correspondingly in 2004. However absolute numbers can give us only partial information. Deeper analysis re quires examining relative figures, such as profit margin (pre-tax profit divided by sales). According to the information from FAME (2005) the average profit margin was 6.49 for EMI Group in the past ten years. In 2005 it was 4.73, while in 2004 profit margin was -2.50, and in 2003 it was 14.68. Thus
