Income elasticity of demand Essay Example for Free

Income elasticity of demand Essay World trade for wheat is greater than for all other crops combined and is cultivated in 128 counties. A farming company specializing in wheat and barley production (Silo Pty Ltd), one of many producers in the international market, is greatly affected by storms in the U.S and South America. These storms have reduced the global wheat yield by 50 per cent. Wheat continues to be the most important food grain resource as it is used in a large majority of foods around the world. Its production leads other crops such as rice, maize and potatoes. Despite wheat’s great importance in the food industry, it would still be regarded as being price ‘elastic’ and have a positive income elasticity, as there are many competitive suppliers around the world, which could possibly lead to fluctuations in prices and prevent large shortages. Price elasticity of demand arises due to the responsiveness of the quantity demanded of a good to change its price, when all other influences on buyers’ plans stay the same. Income elasticity of demand is the responsiveness of demand due to a change in income. Factors that generally affect the supply of goods or services include, the price of factors of production, the prices of related goods produced, expected future prices, the number of suppliers, technology and the state of nature. Demand is also effected by such factors as, the prices of related goods, expected future prices, income, expected future income and credit, population and preferences. If ever there were a shortage of wheat due to bad weather or storms, such that has happened to Silo Pty Ltd, other crops such as barley or maize could be used as an alternative resource, thus the supply would decrease and eventually the demand would decrease slightly as well as there are alternative resources at possibly cheaper prices. This would result in wheat being considered as a normal good in western society as for which demand increases as income increases. Graph 1 shows the situation before the storms hit and the effects after the storms. The demand curve is D and the original supply curve is labelled S0. After the storms hit, the supply curve shifted left to S1. This represents the supply decreasing, further increasing the price. Graph 2 shows the effects of the expected future price rise. Demand increases, shifting from D0 to D1, supply decreases shifting the supply curve from S1 to S2.

Solar System Essay -- essays research papers

The Solar System By â€Å"Delete this text and type your name here.† Introduction As far as we know, there are nine planets locked in orbit around the Sun. Only one, our own Earth, supports life. But there are countless other suns throughout countless galaxies scattered across the expanse of the universe. We still don’t know if life exists on another planet in some other galaxy. Mercury Named for the wing-footed messenger of the Roman gods, Mercury races around its orbit at a dizzying speed of 30 miles (48 kilometers) per second, making the Mercurial year only 88 Earth days long. In contrast, one rotation around its axis—or a single day—takes almost 59 Earth days. Geology Mariner 10 gave us a wealth of information about Mercury when it approached the planet in 1974 and 1975. Because Mercury has no water and barely any atmosphere, no erosion has taken place on its surface. We see Mercury much the way it was soon after it formed. Core We learned that Mercury has an extremely weak magnetic field, which could indicate a hot metallic core, such as molten iron. Geologists think Mercury may be the most iron-rich planet in the solar system. Crust Mercury’s crust seems to be silicate, like that of Earth. Craters The planet’s surface, viewed for the first time via Mariner’s cameras, is covered by craters. The battering occurred during the early period of the solar system when clumps of material were ramming into each other to form the planets. Atmosphere Mercury doesn’t have what we think of as an atmosphere—that is, a gaseous envelope that produces clouds and weather or protects the surface of the planet from some of the harmful solar radiation. The weak magnetic field on Mercury captures only the barest perceptible trace of charged particles from the Sun. Venus Shrouded in the cloak of mystery, Venus, our nearest planetary neighbor, takes the name of the Roman goddess of love. For some unknown reason, Venus rotates on its axis in retrograde—that is, in the reverse direction of its revolution around the Sun. Geology Geologically, Venus appears to have some similarities to Earth. Its crust is probably granitic, overlying a basaltic mantle and a iron-nickel core. The geologic activity that we are familiar with on Earth seems not to exist on Venus, except for the presence two volcanoes along a fault line. ... ...p;  17 Uranus  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  19.18  Ã‚  Ã‚  Ã‚  Ã‚  84 years  Ã‚  Ã‚  Ã‚  Ã‚  16 hours  Ã‚  Ã‚  Ã‚  Ã‚  14.54  Ã‚  Ã‚  Ã‚  Ã‚  4.10  Ã‚  Ã‚  Ã‚  Ã‚  15 Neptune  Ã‚  Ã‚  Ã‚  Ã‚  god of the deep blue sea  Ã‚  Ã‚  Ã‚  Ã‚  30.06  Ã‚  Ã‚  Ã‚  Ã‚  165 years  Ã‚  Ã‚  Ã‚  Ã‚  18 hours  Ã‚  Ã‚  Ã‚  Ã‚  17.23  Ã‚  Ã‚  Ã‚  Ã‚  3.88  Ã‚  Ã‚  Ã‚  Ã‚  8 Pluto  Ã‚  Ã‚  Ã‚  Ã‚  god of the underworld  Ã‚  Ã‚  Ã‚  Ã‚  39.44  Ã‚  Ã‚  Ã‚  Ã‚  248 years  Ã‚  Ã‚  Ã‚  Ã‚  6.4 days  Ã‚  Ã‚  Ã‚  Ã‚  .002?  Ã‚  Ã‚  Ã‚  Ã‚  0.12-0.30  Ã‚  Ã‚  Ã‚  Ã‚  1 * AU = Astronomical Unit (Earth = 1) Conclusion We know more and more all the time about our own solar system.

Tiny by comparison to the Milky Way, our solar system is awesome, nevertheless, when considered in human scale.

Shottky diode

The Schottky diode is an important device which is widely used in radio-frequency (RF) applications. It possesses many similarities to the point-contact diode. In fact many of the early devices were made in the same way as a point-contact diode, although today's devices are made with totally different manufacturing techniques. Unlike conventional semiconductor diodes, which consist of a PN Junction, the Schottky diode is made from a metal semiconductor Junction.This offers a number of dvantages in some circumstances as the diode has a very low forward-voltage drop, and secondly it has a very fast switching speed. Both of these properties make it ideal for many RF applications as well as giving it uses in many other areas, as we shall see. Characteristics. The Schottky diode is what is called a majority carrier device. This gives it tremendous advantages in terms of speed. By making the devices small, the normal RC (resistancecapacitance) type time constants can be reduced, making the Schottky diode an order of magnitude faster than the conventional PN diodes.This factor is he prime reason why they are so popular in RF applications. The Schottky diode also has a much higher current density than an ordinary PN junction. This means that forward-voltage drops are lower, making these diodes ideal for use in powerrectification applications. The main drawback of the diode is found in the level of its reverse current, which is relatively high. For many uses this may not be a problem, but it is a factor which is worth watching when using Schottky diodes in more exacting applications. Variety of Applications.The Schottky diode is used in a wide variety of applications. It can naturally be used as a general-purpose rectifier. However, in terms of RF applications, it is particularly useful because of its high switching speed and high-frequency capability. Schottky diodes are similarly very good as RF detectors as their low capacitance and forward- voltage drop enable them to detect signals which an ordinary PN Junction would not It has already been mentioned that the Schottky diode has a high-current density and low forward-voltage drop. As a result, Schottky diodes are widely used in power supplies.By using these diodes, less power is wasted, making the supply more nd smaller heatsinks may be able to be incorporated in the design. The Schottky diode is used in logic circuits. Although not as common these days, the 74LS (low-power Schottky) and 74S (Schottky) families of logic circuits use Schottky diodes as a core component. The Schottky is inserted between the collector and base of the driver transistor to act as a clamp (see Fig. 2). To. produce a low or logic ‘O' output the transistor is driven hard on, and in this situation the base-collector junction of the diode is forward biased.When the Schottky diode is present, this akes most of the current and allows the turn-off time of the transistor to be greatly reduced, thereby improving the sp eed of the circuit.

Cheerios commercial

This commercial was different than any other cheerios commercial because it involved an interracial couple and their mixed daughter. In the video, you see the little girl and her mother sitting at the table. The girl starts off by saying â€Å"mom, dad said cheerios were good for your heart is that true? † The mother replies, â€Å"Cheerios has healthy grains and it helps with cholesterol so that's heart healthy. † The little girl smirks and walks away.The next scene you see the dad sleeping on the ouch with a whole bunch of cheerios on top of his heart. This video received a lot of backlash on Youth about this interracial couple. One stereotypical thing that was portrayed was the fact that people refer to African Americans as having a lot of heart problems because of what they eat. The little girl obviously understood that and wanted her dad to be healthier by placing the cheerios on his heart. This of course was frowned upon because not all African Americans have hear t problems. Cheerios ended up banning the commercial and they then recreated a new one with the same family.The second commercial involved the dad telling the daughter that her mother was pregnant by using cheerios and in the end she says she would like a dog if she's getting a new baby brother. I feel as though the racial issues African Americans have gone through in the past still do somewhat exist. There are constantly so many stereotypes being made about African Americans. People are ignorant and they are so quick to Judge someone's culture without actually knowing anything about it. I myself am married to an African American man and our children are also mixed but he does not have heart problems nor does anybody in his family.Most categorize people by color and culture but that does not mean that we are all the same. Though slavery was overruled in 1865 and segregation ended in 1964, there are still people out there who believe in it. When people saw this commercial of the inte rracial couple, the people who don't necessarily like or believe in interracial couples also had some things to say about the video. Some of them said they would no longer eat cheerios because of knowing an interracial couple does or was even in the commercial.

marijuana and brain damage essays

marijuana and brain damage essays Though marijuana is illegal, it is the most widely used illicit drug in most developed societies today; over fifty percent of people will use it at some point in their lifetime (Hubbard, Franco, Onaivi 1999). Its peak usage occurred in the 1960s, but is still at a high today. To many peoples dislike, cannabis actually has legitimate medical purposes. Many anti-drug messages provide people with exaggerated claims concerning the undesirable affects of the drug. Moreover, its recent legalization in ten states, for medicinal purposes, has emphasized the need to understand and know the long-term effects on the central nervous system. Pope and Yurgelun-Todd(1996) conducted a blind comparison among college students of regular marijuana users versus infrequent users. Their goal was to determine whether frequent marijuana use can be associated with residual neuropsychological effects. Their findings suggested that although marijuana use may produce some effect in memory functions, that the more significant effects are in the attention-executive system. While the recall memory functions stay reasonably unaltered. Also reported by them is a show of impairments in mental flexibility, abstraction and in some aspects of learning, in frequent users more then less frequent users. Most of the cognitive damage is not big when compared to normal cognitive variability in normal individuals. These impairments would not cause a heavy smoker to stand out from the crowd. This does not mean that they dont have some sort of significance; theoretically speaking, they could still have detrimental effects on a students academic performance. Even though alcohol is legal and marijuana is illegal, Wayne Hall and Nadia Solowij(1998) have found that long-term heavy use of marijuana does not cause the harsh impairment of memory, attention, and cognitive function that can be found in chronic abuse of alcohol. But, the lon...

5 Traits That Your PhD Writer Must Have to Provide You with a Great Sample Paper

5 Traits That Your PhD Writer Must Have to Provide You with a Great Sample Paper 5 Traits That Your PhD Writer Must Have to Provide You with a Great Sample Paper Creating your PhD paper is a huge deal and there are many requirements that have to be met. Unlike undergrad programs, your essays and assignments hold to much higher standards and are judged more critically. If you need some professional assistance to your coursework, you have to find a highly qualified PhD writer. 1. High Levels of Competence Of course, you want to hire the best person for your piece. So, you have to make sure that the writer you are interviewing is competent. He/she should be intelligent, have previous experience with PhD papers as well as behave in a professional manner. The writer who displays the high level of competence in his/her works is the person, whom you should consider interviewing further. 2. Good Communication Skills When it comes to PhD papers, a lot has to be done, there are some revisions to be made, some new pieces of information to be added, and dozens of adjustments that should be incorporated throughout the project. Because of this, you need to work with a writer who has good communication skills. He/she should be easy to contact with, as well as ready to set up the meeting.Moreover, the writer should also be able to easily understand instructions. The person, you are working with, needs to be able to answer specific questions. If you have any questions due to the paper, he/she should be able to answer them. If the writer cannot provide you with his/her own insights, it means that he/she does not actually understand the subject. 3. Good Grades If the writer has some experience, working at the PhD level, he/she is likely to have some already completed assignments. Pay attention to the reviews that other customers have left, and look if there is some information concerning the marks that the students have gained for the writer’s works. If his/her projects have good grades and high marks, it is a sign that you are dealing with a truly professional writer. If the projects have received poor grades, it’s quite better to move on and look for somebody else to help you. 4. Noteworthy Achievements Does the person you are going to hire have any major accomplishments? If the writer has achievements that are related to your PhD project, it is a good sign that such a person is knowledgeable about the particular subject. 5. Relevant Certification Although hiring someone with accomplishments in your field is a great deal, but if the person does not have the certain diploma in the particular field, it is not a fatality. Sometimes people do not enter the universities to get a degree, but they attend specific courses to achieve certificates. Thus, if you meet the writer, who has such a document, you can feel free to hire him/her for your paper. There is a complex system on how to find a trustworthy PhD thesis writer to assist you with your project. Determining the applicant’s competence, communication skills, educational degree, etc. are all great ways to find out the best candidate for your final paper.

Images of Japan Within and Without Term Paper Example | Topics and Well Written Essays - 1750 words

Images of Japan Within and Without - Term Paper Example It is characterized by rudimentary agriculture and pit dwellings (Walt, 1980). Decorated clay vessels are examples of the oldest surviving world pottery. Japan was also characterized by Neolithic and Mesolithic culture of semi-sedentary hunter-gatherer. Japanese culture has evolved from its origin. This study is aimed at examining the images of Japan within and without. These include Japan and Japanese images in the western world. The primary objective is to determine the kinds of images, and how Japan has been seen by the outside world - western images and western myths. The other area of interest is the nationalism of Japan together with key aspects of change in the country; home and family in Japan’s continuity and transformation. Japan as Seen by the Outside World- Western Images and Myths Japan is seen by the western world as a country of cherry trees and volcanoes. Japan’s icons are cherry blossoms and volcano Fudzijama. This makes Japan to be viewed as a loyal, h onorable and brave country. Samurai traditions demand that profits to Japanese only be second to prestige and honor. The virtues of old warriors were courage, loyalty and endurance, which smoothly translated into managerial skills (Black, 1999). Japan is also an isolated country with great contradictions. It has booming cities in the south, which are beautiful and peaceful (Escola & Rikkinen, 1976). This is an indication that Japanese people are hard working and group oriented. According to Totman (2005), the tradition of Japan has been working together by discussion and agreement. Japanese people are hardworking and highly skilled. Japan is also clean and neat. The garden has little stream, waterfall and small bridges. There are also manicured paths shrubs, rocks and flowers. It therefore, has the image of being very neat and cleans (Clavell, 1998). Japan is also seen as unique and different for many years remaining an unresolved riddle and enigma. Though it is in Asia, it is so we sternized, unlike any other country of Asia. It is uniquely adaptable countries where modernity and traditions are consisting of one continuum (Whitney, 1967). In the entire world, Japanese are known to be polite and courteous people (Clement, 1906). Littlewoods (1996) says that Japan’s idea on western images and myths is that different western countries have different views towards Japan. On the other hand, European images also differ from American images. The west has always been seen as an industrialized, urbanized, capitalist, modernized and highly developed. Its concept is therefore a product of 16th century historical processes as people tend to divide the world into west and non west, Japan’s position becomes confusing. The images are based on old pictures and descriptions. The historical perspective of Japanese images is mainly based on historical notes and books written by authors from the west. Historians have for a long time debated on the seclusion of Japan . Few European works in description of Japan, appeared during the period of seclusion, and were exclusively attached to the Dutch factory. Although there were several information limitations, Kaempfer formed the most popular western image in Japan (Clavell, 1998). The two compilations that were widely read were published in New York and London, two years before the expedition of Perry. Perry’s arrival in Uraga was especially felt because of his decorative fine arts. It was also conspicuous in architecture ceramics, religious studies dance, fashion, interior design, literature and landscape gardening among others. The interest of Americans and European first rose from observable images, without an intermediary aid. The popular Japanese imaginations were stirred by fans, curios, kites, parasols, combs,
