An Overview of Christallers Central Place Theory

An Overview of Christallers Central Place Theory Central place theory is a spatial theory in urban geography that attempts to explain the reasons behind the distribution patterns, size, and a number of cities and towns around the world. It also attempts to provide a framework by which those areas can be studied both for historical reasons and for the locational patterns of areas today. Origin of the Theory The theory was first developed by the German geographer  Walter Christaller  in 1933 after he began to recognize the economic relationships between cities and their hinterlands (areas farther away). He mainly tested the theory in southern Germany and came to the conclusion that people gather together in cities to share goods and ideas and that communities- or central places- exist for purely economic reasons. Before testing his theory, however, Christaller had to first define the central place. In keeping with his economic focus, he decided that the central place exists primarily to provide goods and services to its surrounding population. The city is, in essence, a distribution center. Christallers Assumptions To focus on the economic aspects of his theory, Christaller had to create a set of assumptions. He decided that the countryside in the areas he was studying would be flat, so no barriers would exist to impede peoples movement across it. In addition, two assumptions were made about human behavior: Humans will always purchase goods from the closest place that offers them.Whenever the demand for a certain good is high, it will be offered in close proximity to the population. When demand drops, so too does the availability of the good. In addition, the threshold is an important concept in Christallers study. This is the minimum number of people needed for a central place business or activity to remain active and prosperous. This led to Christallers idea of low- and high-order goods. Low-order goods are things that are replenished frequently such as food and other routine household items. Since people buy these items regularly, small businesses in small towns can survive because people will buy frequently at closer locations instead of going into the city. High-order goods, by contrast, are specialized items such as automobiles, furniture, fine jewelry, and household appliances that people buy less often. Because they require a large threshold and people do not purchase them regularly, many businesses selling these items cannot survive in areas where the population is small. Therefore, these businesses often locate in big cities that can serve a large population in the surrounding hinterland. Size and Spacing Within the central place system, there are five sizes of communities:   HamletVillageTownCityRegional capital A hamlet is the smallest place, a rural community that is too small to be considered a village. Cape Dorset (population 1,200), located in Canadas Nunavut Territory is an example of a hamlet. Examples of regional capitals- which are not necessarily political capitals- would include Paris or Los Angeles. These cities provide the highest order of goods possible and serve a huge hinterland. Geometry and Ordering The central place is located at the vertexes (points) of equilateral triangles. Central places serve the evenly distributed consumers who are closest to the central place. As the vertexes connect, they form a series of hexagons- the traditional shape of many central place models. The hexagon is ideal because it allows the triangles formed by the central place vertexes to connect, and it represents the assumption that consumers will visit the closest place offering the goods they need. In addition, central place theory has three orders or principles. The first is the marketing principle and is shown as K3 (where K is a constant). In this system, market areas at a certain level of the central place hierarchy are three times larger than the next lowest one. The different levels then follow a progression of threes, meaning that as you move through the order of places, the number of the next level increases threefold. For example, when there are two cities, there would be six towns, 18 villages, and 54 hamlets. There is also the transportation principle (K4) where areas in the central place hierarchy are four times bigger than the area in the next lowest order. Finally, the administrative principle (K7) is the last system where the variation between the lowest and highest orders increase by a factor of seven. Here, the highest order trade area completely covers that of the lowest order, meaning that the market serves a larger area. Losch’s Central Place Theory In 1954, German economist August Losch modified Christallers central place theory because he believed it was too rigid. He thought that Christallers model led to patterns where the distribution of goods and the accumulation of profits were based entirely on location. He instead focused on maximizing consumer welfare and creating an ideal consumer landscape where the need to travel for any good was minimized, and profits remained relatively equal, regardless of the location where goods are sold. Central Place Theory Today Though Loschs central place theory looks at the ideal environment for the consumer, both his and Christallers ideas are essential to studying the location of retail in urban areas today. Often, small hamlets in rural areas do act as the central place for various small settlements because they are where people travel to buy their everyday goods. However, when they need to buy higher-value goods such as cars and computers, consumers who live in hamlets or villages have to travel into the larger town or city, which serves not only their small settlement but those around them as well. This model is shown all over the world, from rural areas of England to the U.S. Midwest or Alaska with the many small communities that are served by larger towns, cities, and regional capitals.

Ballard T-Th 5:00-6:15 pm Asteroids In our solar system today there are over 30,000 asteroids flying around in all direction colliding with other asteroids and planets, without a care about the destruction they might convey. Our planet Earth is caught right in the middle of all of this action and is liable to entire extinction of any life forms on the planet if a large enough asteroid crosses its path. Any single asteroid has the possibility to erase thousands of years of history and wipeout the human race, as we know it. Asteroids are large or small chunks of rock and metal flying around space up to speeds of 80 000 km/h. These chunks were believed to have formed millions of years ago during the "big bang". These rocks didn’t form any planets and were stuck floating around space on their own or in the gravitation of the asteroid belt. This asteroid belt is approximately 300 million miles from the Sun and it contains thousands of asteroids; some being miles in diame ter. Another theory of the formation of asteroids is that a planet between Mars and Jupiter once existed and after many years it exploded into thousands of pieces that are still revolving around the sun in the form of an asteroid belt. Other asteroids are formed when large meteors collide with large asteroids creating more small ones. These meteors can also collide with planets breaking off chunks of the crust into space. Ceres is believed to be the biggest asteroid that was in space at one point in time. Ceres was believed to be 600 miles wide, making up 1/3 of the total mass of all asteroids. Ceres was the first asteroid discovered and was found in 1801.

Major Project - Essay Example It is getting the whole nation to ask a number of important questions of their own capacity to recover and be resilient in the midst of a crisis resembling economic chaos and growing militancy in the labor front. For its part, the state of Wisconsin through their Republican Governor is turning to thousands of their Democrat leaning state employees for initial answers. Where does patriotism lie in the midst of lavish benefits and indulgence with the impending financial ruin getting to be the main backdrop of the controversy? Keywords: GOP - Grand Old Party, Republican, Democrats PUBLIC EMPLOYEES UNIONS ACROSS AMERICA 3 Public Employees Unions Across America Face Massive Curtailment On Grounds of Averting an Impending Financial Crisis What sets off a statewide protest more conspicuously heard and felt in Wisconsin is the planned amendment to overhaul a system which initially included giving the state a new mandate of declaring bankruptcy and soften financial woes through an eventual re negotiating of wages and so-called lavish benefits of state employees. ... With a historically binding political patronage that tilts heavily on the side of the Democrats since President John F. Kennedy signed the executive order granting public employees the ability to a collective bargaining in 1962, such peripheral political and industrial advantages now face its biggest threat of curtailment on grounds of regaining sound fiscal management and economic parity raised by the Republicans in Wisconsin. The GOP takes the upper hand as the dominant party in Wisconsin while the Democrats and the main protagonists, the affected public employees and the unions, brace themselves for an extended political and judicial confrontation. The showdown PUBLIC EMPLOYEES UNIONS ACROSS AMERICA 4 begins in Wisconsin, home of the first ever unions of public employees in America. This is where collective bargaining for state workers was originally conceived with its long standing political alliance with the Democrats. But when the Republicans took control of the senate, the ass embly and more significantly the office of the Governor, the result was a heightening political confrontation endemic to a two-party political system and an increasingly massive workers’ dissent that is slowly engulfing the whole of America where majority of the states have established politically active, benefits and welfare-oriented unions for public employees. Wisconsin has set the precedence, then and now. Of the total fifty two states comprising the United States, thirty of them have collective bargaining statutes covering state and local employees. Since the 1950’s, government employees’ unions have grown into a major influence-peddling

Relationships between Critical Thinking & Ethics Essay

Relationships between Critical Thinking & Ethics - Essay Example These values are such as justice, wisdom, care, and compassion, which are lacking in the case of execution of prisoners in order to sell their body parts. Critical thinking enables individuals to make decisions based on verified information and truths. In the case of human organ selling, there is an apparent deviation in the act by the military through their brainwashing due to money. The military and Dr. Dye fail to identify the importance of life due to greed for money. In both cases, the military and the doctor failed to ensure the human right to life. Restricting to logical rules and guidelines will not require ethical decision-making process. Critical thinking determines ways of analyzing and differentiating facts from fiction or a way of understanding or making new discoveries (Ruggiero, 2011). Critical thinking influences culture that determines the way of life of a person through equipping one with a mental process of evaluation. The mental process forms a ground that determines the ethical standards. An inference that critical thinking forms the overall determination of moral values can be made. In the scenario considered, if the military, doctor, and the prospective customers did put considerable thought to the inhumanity of the business, they would not have been

Left to Tell Essay Example for Free

Left to Tell Essay Immaculee Ilibagiza was a college student in Rwanda during the 1994 genocide in which nearly one million people died. Her story is a remarkable testimony to the power of God’s grace to strengthen us during times of trial and to live the teaching of the Gospel in the face of overwhelming evil. Her story is told in the novel Left to Tell, published in 2006. In Rwanda, there were three tribes, and each citizen belonged to one of the tribes. These tribes were the Hutu, which were the majority, Tutsi, which were the minority, and an extremely small number of Twa, which was a pygmy-like tribe of forest dwellers. Immaculee and her family belonged to the Tutsi tribe, and because of this they were under great threat. The Hutu tribe wanted to kill every single Tutsi in Rwanda, and this was the cause of the genocide in 1994. The Tutsi tribe was taller, lighter-skinned and has narrower noses, and Hutus were shorter, darker, and have broad noses, and each person had an identity card which labeled what tribe they were in. This is how the Hutus chose their victims, by their identity card or their looks. Not only was Immaculee under death threat, but she was also being treated unfairly by her peers. She was an extremely smart girl, and because of her being a Tutsi, she was not able to get a scholarship to college. Before the genocide came into full effect, there were many reports on the radio warning the Tutsis of killings to come. One day, Damascene, one of Immaculee’s three brothers, told his family that he actually saw the killers, but they refused to believe him. They started to get nervous when President Habyarimana, the president of Rwanda, was killed. His plane was shot out of the sky, and this event sparked the beginning of the genocide. The more severe the radio reports were, the more nervous Immaculee and family got. Immaculee tried not to show her fear, because if she did, she would not be able to stay strong through this event. Many neighbors gathered around her home because her father, Leonard, was a very respectable man in the neighborhood. One day, fifty Interahamwe armed with knives and machetes attacked the Tutsis outside of the Ilibagiza home. Leonard gathered more than one hundred Tutsi men together and rushed toward the killers. They tossed stones at them and scared them away. After this, Immaculee’s father gave her a red and white rosary and told her to keep it always, and she did. The killers came back a second time, but this time no one joined Leonard to fight back. After this event, it was known that it was not safe, and Immaculee could not stay at her home. Immaculee and Augustine, a friend who was staying with the Ilibagiza family, were soon on their way to the home of family friend and local pastor, Pastor Murinzi. There, she was forced to hide in a small bathroom with seven other women, and there she had many spiritual experiences. While Immaculee was hiding in the bathroom, she could hear the killers and other people talking about what was going on. Immaculee still did not know whether or not her family was alive. She cursed the killers, and hoped that they got treated as they were treating her fellow Tutsis. Because of this feeling, Immaculee could not have a feeling of calmness, and she was very angry. She prayed, but the devil was telling her that praying would not work, when she has so much hatred in her heart, and is wishing such horrible things on the killers. In a dream, Jesus appeared to her, and told her to forgive the killers and to stay calm and he would protect her. She did as Jesus said, and forgave the killers, and she was one of the few whose life was spared during the genocide. Some people do not pray, and do not have God in their lives. These are the people that contribute to the evil and destruction of the world. The killers of the 1994 genocide were definitely evil, and they were being tempted by the devil to do such evil acts. Lies were made up just so they could kill Leonard, and the rest of the Ilibagiza family, who were very well respected in the town. Some people do not think over their actions, and do not make the distinction between what is right and wrong. Some people just listen to other people because they are scared, so they do evil things, just because someone told them to. Unfortunately, I do believe that something this terrible may happen in our own country. In the last decade, some evil things have happened in America, such as the planes hitting the World Trade Center on 9/11 and the plane hitting the Pentagon, in the same day. Islamic people performed both of these evil acts. Most Americans have hatred for these people, and some especially because loved ones died in the World Trade Center. Since then, there have been bomb scares, and the hatred has just been building up. If another tragedy occurs, Americans will most likely rebel, and want these people extinguished from the country, whether they look innocent or not, just for the sake of the country. It is much better to forgive, than to hate and hold grudges. By forgiving, you are following in Jesus’ path and becoming a better person. By hating and seeking revenge, you will harbor hatred in your heart and be an extremely angry person for always thinking of ways to get revenge. I have learned that by forgiving, instead of hating, your prayers will be answered quicker. By following in the footsteps of Jesus, forgiving all who have harmed you, you will be a happier person, and by God being an important part of your life, you will have a good life. I will most definitely live differently after reading this book. Nothing in my life has ever compared to anything that Immaculee went through, and I should be extremely grateful for that. I will try to forgive all who have done wrong to me, and although it may not be easy, I know that God is there guiding me every step of the way.

Odyssey Theme Paper :: essays research papers

The Odyssey Theme Paper   Ã‚  Ã‚  Ã‚  Ã‚  The Odyssey is mainly about the tribulations of a great hero; that hero would be Odysseus. Although Odysseus does not appear in this epic until the fifth book, he is still the main character. Odysseus, whom I will call the hero, has many tribulations in this epic. Read on to see what I mean.   Ã‚  Ã‚  Ã‚  Ã‚  This story starts right after the Trojan War; the Greeks have won, thanks to one of Odysseus’ great ideas. All the kings are now trying to get back home to their families. Odysseus, however, will have the most problems.   Ã‚  Ã‚  Ã‚  Ã‚  The first place Odysseus goes after the war is the land of the Ciconians. He and his men raid the island and destroy the village. However the next day, more Ciconians arrive and defeat Odysseus and his men. Several men are killed, and Odysseus experiences his first of many sorrows and tribulations. Next, the hero goes to the land of the lotus-eaters. Some of his men eat the lotus plant and instantly want to stay there and never leave. Odysseus manages to get his men away from the island, and they leave. Then the hero arrives at the home of Polyphemos. Polyphemos is a huge cyclops and also a cannibal. Odysseus and twelve of his men are trapped inside Polyphemos’ cave and can’t get out. Polyphemos comes back and eats some of the hero’s men. The next night Odysseus gets the cyclops drunk on wine, and when it falls asleep, Odysseus and his remaining men blind it with a large pole. He and his men barely escape with their lives and continue on the voyage. The hero soon lands on Aeolus’ island. (Aeolus is the Keeper of the Winds.) He helps Odysseus on his way by giving him the right winds to take him home to Ithaca. The hero gets within site of his home but a hurricane blows him all the way back to Aeolus’ island. This time Aeolus turns Odysseus away, and he is forced to continue his journey. The hero and his men next end up in the Land of the Midnight Sun, where the Laestrygonians live. The Laesrtygonians attack the men and sink eleven of the twelve ships. Only Odysseus’ ship and forty-four men escape to safety. This is one of the most painful tribulations Odysseus faces on his journey. Soon afterwards, Odysseus and his now small crew arrive on Circe’s island.
