Reillys Law of Retail Gravitation

In 1931, William J. Reilly was inspired by the law of gravity to create an application of the gravity model to measure retail trade between two cities. His work and theory, The Law of Retail Gravitation, allows us to draw trade area boundaries around cities using the distance between the cities and the population of each city. History of the Theory Reilly realized that the larger a city, the larger a trade area it would have and thus it would draw from a larger hinterland around the city. Two cities of equal size have a trade area boundary midway between the two cities. When cities are of unequal size, the boundary lies closer to the smaller city, giving the larger city a larger trade area. Reilly called the boundary between two trade areas the breaking point (BP). On that line, exactly half the population shops at either of the two cities. The formula is used between two cities to find the BP between the two. The distance between the two cities is divided by one plus the result of dividing the population of city B by the population of city A. The resulting BP is the distance from city A to the 50% boundary of the trade area. One can determine the complete trade area of a city by determining the BP between multiple cities or centers. Of course, Reillys law presumes that the cities are on a flat plain without any rivers, freeways, political boundaries, consumer preferences, or mountains to modify an individuals progress toward a city.

Sociology Course At Environmental Problems - 1858 Words

The introduction to sociology course this semester turned out to be a very intriguing class. I had prior knowledge and connection to the subject, but still I thoroughly enjoyed the class and feel that I learned and developed further knowledge into the subject of sociology. Many of the topics, discussions, and assignments I really enjoyed doing, and I am glad that the course turned out to be as great as it was. Due to this, I choose to not write about any activities or topics that I didn’t enjoy learning, because all in all, I really enjoyed everything about this course. I have a connection to sociology since a young age, and I very much enjoy studying all the topics we have learned thus far in this intro class. To write about assignments or topics that I didn’t like would be hard for me because I would have to make up excuses to why I didn’t enjoy something discussed. My favorite topic that we discussed in class was environmental problems. I really enjoy looking at environmental problems and the implications that arise in society stemming from the environmental problems in our world. We discussed the types of pollution and the complications that come from the different types of pollution. I really enjoy learning more about the topic of environmental change, because I already consider myself to be fairly interested in the topic prior to its discussion in class.

The Importance of Sleep Essay - 1681 Words

Sleep is an extremely interesting phenomenon in which the mind almost completely departs from the usual realm of consciousness. It is distinguished from quiet wakefulness and a decreased ability to react to stimuli where we become less aware of our surroundings. However, it is more easily reversed than being in hibernation or a coma. It is a function that has been extensively researched by many. After all, we would not have evolved a mechanism that forces us to spend one-third of our lives sleeping unless sleep did us some good. What good does it do tough? Over the years, many theories have been proposed as to why we need sleep. The simplest is that it saves energy. An individual’s energy expenditure and demand is reduced during the day,†¦show more content†¦A sleep deprived driver, believe it or not, is as dangerous as a drunk driver. Sleep also strengthens learning and memory, including both motor skills and language related tasks. When you learn something, your mem ory improves if you go to sleep within the next 3 hours, and it deteriorates after a sleepless night. A good night’s sleep can also improve learning the next day. When people learn a new difficult motor task, such as a video game skill, the brain areas that are active during the learning become reactivated during one’s sleep that night. The brain replays the same patterns they had during the day, only faster. The amount of functioning and activity in those areas during sleep predicts the amount of improvement the next day. In learning, wakefulness and sleep play complementary roles. Researchers have demonstrated that learning strengthens the appropriate synapses during wakefulness and weakens other synapses during sleep. Therefore, REM sleep is crucial for organizing pieces and the associations between them needed for forming lasting memories. Organizing these pieces within your brain requires information gained through learning. Learning is a complicated process that is completed subconsciously by gaining new knowledge and skills and modifying previous ones. Three basic parts of learning include acquisition, consolidation, and recall. During acquisition, the brain receives information and stores it within its neural circuits as memory.

Heroism In Sir Gawain And The Green free essay sample

Knight And Beowulf Essay, Research Paper Heroism in Beowulf and Sir Gawain and the Green Night A hero, harmonizing to Webster # 8217 ; s New World Dictionary, is person who commits an act of singular courage or who has shown great bravery, strength of character, or another admirable quality. He is looked up to for the brave and baronial things he has done. Though Beowulf and Sir Gawain are both considered heroes they each have many different qualities. For Beowulf his repute as a hero depends on the sentiment of others within his society, for Gawain Christianity determines his bluster. In order to understand how they are both considered a hero in their society we must look at the many differences their several societies possess. One major difference between the society that Beowulf lived in and the one Sir Gawain lived in is their positions on faith. In Sir Gawain and the Green Knight, the universe described is one of order, where Christianity plays an of import function. We will write a custom essay sample on Heroism In Sir Gawain And The Green or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Sir Gawain fits absolutely into this universe as a Knight who is brave non because he of course possesses this courage, but because he puts his religion in God. Beowulf on the other manus describes a universe where faith and manners were non of import. Beowulf # 8217 ; s actions are judged by others and how they affect society, and non by any spiritual force. As an heroic poem hero, Beowulf possesses the qualities of heroism, trueness, generousness, and award. He fights because he must in order for his state to last. Although he is a hero he is invariably cognizant of his ain mortality, and it is in conflict that his courage is tested. The heroic poem hero lives in a honor/ shame society, where a adult male # 8217 ; s good name is his most prized ownership. Because Beowulf lives in a hierarchal society it is of import for him to get the better of Grendel, his female parent and the firedrake. Genealogy is really of import in the hierarchal society, so if he had failed he would non merely convey shame to himself, but to his household and state. Beowulf # 8217 ; s greatest value is his courage, although it may look that his crow is un-heroic. It is nevertheless necessary for Beowulf to present his unwritten sketch in order to be given the regard he deserves. It is non that Beowulf is non in hunt of celebrity, because he is, it is merely that he accomplishes acquiring celebrity by assisting others and get the better ofing threats to their society. He does non lie or pull strings others to accomplish acknowledgment ; he uses what is truly his, he bravery. The virtuousnesss of a knightly hero are similar to the heroic poem hero including, heroism, generousness, trueness, award and accomplishment in conflict. One chief difference is the significance given to loyalty during this epoch. It is besides necessary for the knightly hero to possess moderation, courtesy, regard for adult females and courtly accomplishments. He must be able to execute in tribunal and besides on the battleground. Similar to heroic poesy, the knightly knight is tested through efforts of weaponries. One major difference is in their motive. An heroic poem hero will merely travel into conflict when necessary, while the knightly hero will put out to happen an escapade in which he can turn out himself weather. The knightly hero will seldom contend in order to support his people, but instead in defence of a peculiar ideal. Another major difference between the two is in the type of internal conflict they engage in. Beowulf, our heroic poem hero, is tested in physical conflict against a monster, as heroic poem heroes need to turn out themselves against another. Sir Gawain # 8217 ; s undertaking is religious, and psychological. He must go through all the demands of the knightly knight in order to be successful in conflict. Beowulf and Sir Gawain are such immensely different characters that the term collapses into a construct wholly dependent on its context. The standards upon which they are each judged is immensely different because of the different times their narratives take topographic point in. In Sir Gawain # 8217 ; s universe those who obey the spiritual, societal and knightly codifications of his kingdom can be considered a hero. In Beowulf those who really create and support society itself are considered heroes. 373
