Models of Economics Research Paper Example | Topics and Well Written Essays - 1000 words

Models of Economics - Research Paper Example Its main thoughts are that; free markets are better situated to allocate the scarce resources in any economy; minimum government or state intervention in the economy is important and works best (Pindyck & Rubinfeld, 1981). It contends that the supply of money ought to be maintained at equilibrium with money demand. This prevents distortion of the economy through increased money supply, which leads to various evils such as inflation, and excess demand that is not be met by the available supply. Socialism is an economic system that lies between capitalism and communism. It seeks to redistribute the wealth more equitably through the common ownership of natural resources and key industries such as public utilities and manufacturing industries. The state involves itself in central planning. Production of goods and provision of services, including their prices and distribution is centrally controlled (Pindyck & Rubinfeld, 1981). This economic model puts emphasis on improving developing nations’ economies. This economic model focuses on ways to stimulate growth in those countries through enhancing aspects such as education, health, working conditions, market and improving both international and domestic policies and systems. Their focus is to figure out how developing/poor countries would be changed into thriving ones (Pindyck & Rubinfeld, 1981). Since political and social circumstances of various countries vary substantially, tactics for turning a poor nation are usually unique and country specific. For example, the government strives to maintain the economy at equilibrium by either controlling or sharing of natural and state resources or controlling money supply in order to avoid economic distortion through increased money supply. John Keynes’ economic theory is applicable in many economies in the world since it was first developed. Keynes advocated for the regulation of economies using controlled money supply and

The rate of reaction Essay Example for Free

The rate of reaction Essay The experiment will end when I take the third reading of 30cmisodium thiosulphate solution, 20cmi water. The safety goggles are the most important aspect of the experiment, as it is crucial to maintain a high standard of safety when working with corrosive chemicals. Diagram: Graph to show predicted appearance of results Method and Results I carried the experimental investigation as stated in the Plan section, under Experimental Procedure. Having gained satisfactory results, I have arranged them in a table. Table of Results cmi of Na2S3O2 Time taken (seconds) Mean results solution 1 2 3 (average). To draw my graph, I used the reciprocal function on my calculator on each of the averages, to gain a number that can be used to draw up a graph to show direct proportionality between 1/Average Time taken and concentration of sodium thiosulphate. Conclusion In terms of drawing a conclusion from my results, I can say that they compliment my prediction, as shown by the similarity in my prediction graph (a straight declining line), and also generally in the description of inverse proportionality. As anticipated, inverse proportionality is shown between the concentration of sodium thiosulphate and the time taken for the solution to turn opaque. Na2S2O3 + 2HCl 2NaCl + S + H20 + S02 Scientific Explanation As the hydrochloric acid particles and the sodium thiosulphate particles collide into each other solid sulphur is given off and gives the solution a yellowish tinge. After a while this sulphur builds up and clouds the solution to the point when the cross beneath becomes cloaked. The particle collision theory states that the more of a particular chemical there is present in a solution (in my case sodium thiosulphate) then the more it will collide with the other particles (the particles that concern my experiment are the hydrochloric acids). Therefore, if a 100% concentrated solution of sodium thiosulphate is added to a solution of hydrochloric acid, all the particles will collide more often, and the reaction will occur quicker than a 60% sodium thiosulphate 40% water solution, because the 40% water has replaced what used to be sodium thiosulphate, thus reducing the speed of the reaction. Another point to make is the time of the reaction increased rapidly towards the end of my results. Evaluation The results I have obtained were of quite a high general standard, however there were a few minor anomalies. One anomaly was the second result for 30cmi of sodium thiosulphate solution. Here is the extract from my table of results, with the anomaly shown in italics. 30 472 506 493 490 It stood out as being an abnormally long time taken, in comparison with the other two results, and also seen in the effect on the graph of results it has. This could be for a number of reasons. Firstly, going back to the planning section, there is the issue of temperature control, which was left aside despite being recognised as an influencing variable. If left uncontrolled then chances are that anomalies like the above will occur. I have decided not to ignore this result because the unconformity is only slight Also, the slight inconsistencies between each group of three results are also down to the fluctuating room temperature. These errors however, are only slight and therefore are not to be worried about in terms of being insufficient for drawing solid conclusions. I still believe my results to be reliable, as they average out quite impressively. There are minor differences in each of the sets of three readings that were bound to occur due to uncontrolled temperature. The differences are merely fractional, and the averages worked out give a very clear picture of ideal results. There were bound to be the odd fluctuation in the length of time for the solution to turn opaque because of human error. Every time it is myself that judges when the solution has turned sufficiently opaque and I stop the watch systematically. Because my reflexes are not perfect it may seem like one measurement was longer than another, when it was only my slow reactions that distorted the result slightly. The particle collisions theory may also be to blame because if the region of the solution directly above the cross X had a larger amount of collisions, just by chance, then the reaction time would be quicker than average. I would suggest that in further experiments, the variable of heat be included, and the pair who carries out the investigation work as a team and play different roles in the experiment. One of them should time the reaction as I did, and the other should keep the temperature as constant as possible. That way anomalous results will be almost entirely eradicated. The other two issues of human reflexes and of chance of areas of collision are unfortunately uncontrollable. Some kind of computer will surely be able to judge when a solution has turned opaque better than a human being. To test my conclusion, I would suggest doing a similar investigation, but with magnesium strips instead of sodium thiosulphate. It will be easier to judge reaction time because one would only have to stop the watch upon seeing the magnesium completely dissolve. Also using magnesium in an experiment is a lot simpler and cheaper than using sodium thiosulphate.

Comparing two war poems written by Wilfred Owen: Dulce et decorum Est E

Comparing two war poems written by Wilfred Owen: Dulce et decorum Est and Anthem for Doomed Youth. In this essay I will be comparing two war poems written by Wilfred Owen: ‘Dulce et decorum Est’ and ‘Anthem for Doomed Youth’. By comparing the two I will be able to distinguish the fact that Wilfred Owen is very anti-propaganda and why he feels so strongly about this. The two poems have many similarities but also a fair amount of differences, which I will be discussing in this essay. The two poems have a strongly anti war message and in both the victims of war are the young men who’s lives are wasted. ‘Dulce et decorum Est’ uses the description of a gas attack to show how horrific the reality of war is. Owen describes the victim with, ‘The white eyes writhing in his face†¦the blood†¦gargling from the froth-corrupted lungs.’ The physical horror of this helps to shape his message. It is addressed to the propaganda poet Jessie Pope and tells her that it is a lie to say that it is sweet and honorable to die for one’s country. A similar message in ‘Anthem for Doomed Youth’ describes the slaughtered young men who ‘die as cattle’. Owen expresses his anger in a set of contrasts between a real funeral and the lack of a funeral for these young men. For example, instead of a service with a choir, they only have ‘the shrill demented choirs of wailing shells’. As you would expect, the tone and mood of both poems is deeply serious as Owen has a strong message in both of them. However, they are different. ‘Dulce et decorum Est’ expresses a great deal of horror and anger. The horror is set aside for the terrible pain and terror of the gas attack, not only for the victim but also for the poet. He writes, ‘In a... ...ack, making a strong message to contradict the vague, Latin phrase about how sweet it is to die for your country. In ‘Anthem for Doomed Youth’ Owen develops a singe image, the idea of the funeral ceremony for the dead. The first line asks about the ‘passing bells’ and the rest of the octave describes the various sounds of war, which are substituted for the funeral bells. This includes the ‘monstrous anger of guns’, the rattling of the riffles and the wailing of the shells. The sestet begins by asking where are the candles for the funeral service but goes on to tell us that ‘holy glimmers of goodbyes’ in the eyes of the boy soldiers will have to instead. The funeral cloth placed over the coffin is replaced by ‘the pallor of girls brows’. Instead of flowers, they have ‘the tenderness of patient minds’. All the images are based on the original comparison.

jane pittman :: essays research papers

Jane Pittman was born into slavery on a plantation in Louisiana. In the past, Jane’s slave name was â€Å"Ticey.† Jane grew up without parents because her mother died when she was still young and she knew little about her father. As a preteen, Jane worked in a large house, caring for white children. On a scorching day near the end of the war, exhausted confederate soldiers paid a visit, followed soon after by Union soldiers. As Jane was serving the soldiers water, a Union soldier, Corporal Brown, told Jane that she will soon be free and can then visit him in Ohio. He tells her to change her slave name to â€Å"Jane.† The changing of her name symbolized a changing of lifestyle; no longer would she be recognized as a slave, but as an actual human-being with an identity of her own. The owner of the slaves on the plantation freed them all, including Jane. Jane and the freed slaves left the plantation. They’re destination was undecided, but a woman named Big L aura lead the group. Jane thought about going to Ohio to find Corporal Brown. While sleeping in a farm house, the Ku Klux Klan barged in and killed everyone, except for Jane and a young boy named Ned. Ned happened to be the son of Big Laura. Jane and Ned continued on their own, heading towards Ohio. They met a few people on their trip who had some sympathy for blacks. They always told Jane that Ohio was too far, and that she should go back to the plantation. Jane and Ned became exhausted from their long journey. One day, a white man named Job gave Jane and Ned a lift and allowed them to rest at his house, even though his wife disagreed with how her husband treated blacks hospitably. The next day, he took them to a plantation managed by Mr. Bone. Mr. Bone offered Jane a job, but believed her to be incapable of handling the work; however, Jane convinces Mr. Bone that she is capable of handling the work and he agrees to pay her six dollars a month, minus the fifty cents that went toward Ned's education. Later, the original owner of the plantation, Colonel Dye, buys back the plantation with the money he borrowed from the Yankees. Many black people began fleeing the south when they saw that their conditions were worsening.

Alcohol Abuse is dangerous for Everybody Essay

It is well known that alcohol abuse turns into a serious problem in our society because of several facts. More and more people, especially young people, drink a lot of alcohol; as a result, they don’t know when they have to stop and the alcohol use turns into an alcohol abuse. The question, which I ask myself, is: How is it possible that alcohol turns into a serious problem in our generation and which are the flash points? First of all, in every country are different age limits when people are allowed to consume alcohol. Some countries allow drinking beer and wine at the age of sixteen and all other alcoholic beverages at the age of eighteen. As an example in Switzerland, where I come from, the law allows us to start drinking at the mentioned ages. So Swiss people learn to deal with alcohol, everywhere in life, at a young age. Also, we are allowed to drink, so we get to know our limits faster. As you can see there is no allure to do something illegal by drinking alcohol with sixteen because it is allowed. In this way, we don’t drink to be cool; it is just all the time a part of parties, nice dinners or other special times in our life. Of course everybody has a story when we didn’t know when we had to stop drinking, but that happens to everybody and is a part of the process in learning to deal with alcohol in life. Even if we know it, we do sometimes abuse alcohol. Whereas, in the United States of America you aren’t allowed to drink alcohol till you are twenty-one. The law allows you to drive a car with sixteen, but not to drink alcohol. What I see all the time here is that people under twenty-one uses every chance to drink alcohol. If there is alcohol at a party, they use the chance and drink as much as they can in a very short amount of time. Just because they can drink alcohol illegal and this seems to be very exciting young people do it. At first they feel still okay, maybe a little bit dizzy, but after a certain time, they are completely passed out. As you can see most of them have no idea which effects alcohol have and just drink without thinking about it. Finally, they often exceed their own limits without knowing it. But because they’ve never learned to deal with alcohol, Americans do a lot of not willing alcohol abuse. This alcohol abuse can cause different bad effects in our lives. As a beginning, more and more people drink too much alcohol and then drive in their cars. People have accidents on the road caused by â€Å"drink and drive†. It is not familiar to everyone that a lot of people die in car accidents. It can be a friend, a family member or just a stranger, but it doesn’t matter who died, it just matters that you took the life of somebody. Another effect is that you may have drunk so much that you have to go to the hospital and they will pumping-out your stomach. And this is in no way healthy for your body! People can get angry and aggressive if they had drunk to much alcohol. As a result, they start to fight with no reason or get mad at others just because they feel another way when they drunk too much. Also, you can get in big trouble with the police after all these effects, which doesn’t look nice in your report. Another thing is you have to keep in mind that you don’t just endanger yourself, you endanger all people around you too. Even if you drive drunk or if you turn to another personality, when you get drunk, you may disarrange others and get them in trouble. Maybe you have to think about the people around you too. For example, if you are passed out, there are always people who care about you, so they will take care of you in such situations. And to disarrange people isn’t always what you want and you will regret it for sure the next day. As a conclusion, everybody in our society knows that alcohol is no longer just something to drink, which all of us enjoy because of a nice occasion. Alcohol gets more and more really dangerous for our society. However, some people do alcohol abuse and at the moment they do it, they never think about the consequences in their life caused by this abuse. But there are really bad consequences and they are not good for everyone. Our society has to think about this problem and try to do something against it, avoid it!

amadames essays

amadames essays The main actors and their characters they played are: Wolfgang Amadeus Mozart Tom Hulce Antonio Salieri Murray Abraham Mozarts dad Roy Dotrice Mozarts wife Elizabeth Berridde Emperor Joseph II Jeffery Jones The movie Amadeus was based on two composers, Mozart and Salieri. In the begging of the movie Salieri tries to commit suiside. A priest comes to see Salieri to ask him if he has anything to confess. Salieri then begins to unravel the story of Mozart and Salieris life together. Mozart has been a great composer since he was four years old. Salieri on the other hand not as good and would never be as good as Mozart. In the movie you can see how jealous Salieri is of Mozart. Salieris father was against him playing music, and on the other end Mozarts father praised it and insisted on it. Salieri wanted to play music more than anything in the world. One day while in church, Salieri asks God to let him be a great composer and in return he would give him his chastity and write for God. The next day Salieris father died and this was a miracle in Salieris eyes. His family had to go to Vienna where Salieri then became discovered. Salieri worked his way up to the courts and was the Emperors composer. Mozart was to perform for the Emperor, when Salieri got news of this he grew anxious to meet the great composer. He wanted to see what this marvelous composer looked like with all the talent he possessed. The story then goes on about Mozart composing operas and pieces for the Emperor. More and more Salieri was growing to hate Mozart, because he was not as good and realized he would never be. In the middle of the movie Mozart finds out that his father has died. This slowly kills Mozart, he cant write, he drinks more and more, and his relationship with his wife is suffering. Salieri see...

Chico, Muchacho, and Other Spanish Words for Children

Chico, Muchacho, and Other Spanish Words for Children Chico, muchacho, nià ±o - and their feminine equivalents, chica, muchacha, and nià ±a - and just a few of the words you can use in Spanish to refer to children. But they arent all used in the same way. In most cases, youre safe to use any of the above words to refer to boys and girls. However, in some cases they can have more specialized uses. Using Chico and Chica As a general adjective, chico is simply a word for small, especially when referring to something that is smaller than other beings or things of its type. When it becomes a noun referring to people, however, it usually refers to someone of a young age rather than someone of short stature. The age of children used for chico and chica varies somewhat with region. However, it is often used as a term of affection for people other than children. For example, in Cuba it frequently is used to address friends, something like hey dude or buddy might be in American slang. It is also very common to use chica when referring to young, single women, especially ones in which men might be interested in for romantic purposes - something like the equivalent of babe. To a lesser extent, chico can fulfill a similar role. Similarly, the two terms commonly are used for girlfriend and boyfriend, respectively. The main characters in a movie, TV show or novel are often referred to as chico or chica, especially if they are young and attractive. Using Muchacho and Muchacha When referring to adolescents or teenagers, muchacho/a can usually be used interchangeably with chico/a. In most areas it isnt used often when referring to younger children. Muchacho/a can also be used to refer to a young servant or maid. Using Nià ±o and Nià ±a Nià ±o and nià ±a are more general and sometimes slightly more formal words for children. Their use might be preferred in situations where wed talk about a child in English rather than a boy or girl. For example, a school handout might say something such as Cada nià ±o debe leer un libro por mes for Each child should read one book per month. (Following the Spanish rule of gender, nià ±os can refer to a mixed group of boys and girls, not necessarily just boys. In sentences such as the above, the context suggests that cada nià ±o refers to each child, not necessarily just each boy.) Nià ±o is also used in situations where the speaker is referring to young age or inexperience in general. For example, a child soldier is a nià ±o soldado, and a street child is a nià ±o/a de la calle. Similarly, someone who is worse than a child is peor que un nià ±o - words such as chico and muchacho wouldnt work well in that context. Other Words Referring to Children Other words for talking about children include: Hijo and hija refer specifically to a son or daughter, respectively. Nià ±o/a can also be used with the same meaning if the context is clear.Criatura, a cognate of creature, is sometimes used an affectionate term. For example,  ¡Quà © criatura hermosa! might be translated loosely as What a beautiful little angel! Note that criatura is always feminine, even if it refers to a boy.Descendiente can be used as a replacement for hijo or hija; it is used much more than the English descendant. The word can be either masculine or feminine depending on whether it refers to a son or daughter. It can also refer to descendants such as great-grandchildren.Bebà © is the most common word for baby. Note that it is always masculine, even when referring to a girl.
