Vision and Hearing free essay sample

Proprioception is like a third sensory modality that supplies feedback to the solely on the status of the body internally, the first two senses being interoceptive and exteroceptive. The proprioceptive ability that one possesses is the sense that specifies whether the body is moving at the required effort , as well as other body parts are positioned in relation to each other. The ability to estimate weight of an object, the force and time at which our muscles must be contracted are examples of our proprioceptive ability. Examples of proprioceptors are muscle spindles also called stretch receptors and their associated 1a axons. These receptors make up the somatic sensory system that is focus on body sense or proprioception. The muscle spindle consists of several types of speacialized skeletal muscle fibers that are contained within a fibrous capsule. In the middle region of this fibrous capsule group 1a axons are wrapped around the muscle fibre on the spindle. We will write a custom essay sample on Vision and Hearing or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Group 1a axons are the fastest and largest of the group 1 axons, which are also the thickest myelinated axons in the body. When a weight is placed on a muscle , the muscle lengthen and the muscle spindles are stretched. The stretching causes of the spindle causes depolarization of the 1a axons endings, this is caused by mechanosensitve ion channels. The 1a axons enter the enter the spinal cord through the dorsal root, from here they branch repeatedly and then form synapsese on both interneurons and alpha motor neurons of the ventral horns. The alpha motor neurons react by increasing its action potential frequency, this then causes the muscle to contract. The muscle spindle also contains intrafusal fibers and receive their motor innervation by a different type of lower motor neuron called Gamma motor neurons. When the extrafusal muscle contracts it becomes shorter, the intrafusal fiber also becomes shorter, this means that the 1 axons become silent and would no longer provide information about muscle length. However this is where the gamma motor neurons become activated at innervate the intrafusal muscle fibre at either end of the spindle. This causes contraction of the muscle spindle, therefore pulling on the noncontractile equatorial region and keep the 1a axons active. Another source of proprioceptive input in the skeletal muscle is the golgi tendon organ, which monitors muscle tension or force of contraction. The golgi tendon organs are situated in series with the muscle fiber and spindle and is located at the junction of the muscle. A special feature about this source is that it is innervated by 1b sensory axons, which are a little bit smaller than 1a axons. The different anatomical arrangements between the muscle fiber and the golgi tendon organ is what distinguishes the type of information it provides. The 1a axons from the muscle spindle offers muscle length information, the golgi tendon organ give muscle tension. The 1b axons enter the spinal cord, where they branch repeatedly and then synapse on interneurons in the ventral horn. Some of these interneurons connect with the alpha motor neurons which are inhibitory. This is usually called reverse myotatic reflex. There are certain factors that can influence our perception and sensation, this includes, alcohol, drugs and nerve damage. These factors can disrupt the proprioceptive ability by decreasing the feedback quality.

Unfair Treatment for Native Americans essays

Unfair Treatment for Native Americans essays Unfair Treatment for Native Americans Our forefathers forced thousands Native Americans were forced to leave their homes. They faced massacres that caused their population to decrease immensely. Between 1880-1980 half of Native American Children was drove form their home to boarding schools hundreds of miles away to be deculturized. Native American babies were adopted into Euro-American families and were never to find out who they were or where they originated from. Less than thirty years ago the United States Indian Health Service (IHS) conducted a program of involuntary sterilization that effected approximately forty percent of all Indian Women. IHS also gave Alaskan children the hepatitis B vaccine, a banned vaccine that correlates with the HIV virus. Thousands suffered and died of malnutrition and disease due to the circumstances America created. America surely bent over backwards to kill off the Indian population. At about the junior high age level Children will learn about the Holocaust, a time period when Germans liquidated thousands of innocent Jews. United States schools will stress how awful this was and how evil the Germans were. While this may be true, the United States has alike history with Germany. School children are not taught how cruel and evil our forefathers were. Some of the German leaders were hung after the Holocaust for their Crimes against humanity. No one was ever punished for all of the wrong doing to the Native American people. While what Americans did to the Native Americans may not be as extreme as the Holocaust, it is not excusable. What America did was indeed a Crime against Humanity. Today the United States Native Names are used to name professional sports teams such- Atlanta Braves, Cleveland Indians and Washington Redskins. Along with the team names the U.S. Also uses the Indian mascots such as- feathers, beads, buckskins, spears, etc. Despite th...

Hurlyburly Play Character Analysis

Hurlyburly Play Character Analysis If Hollywood were a large stone in the middle of a swamp, then David Rabe’s Hurlyburly represents all of the creepy crawlers and slimy disgusting gunk you find underneath the rock. This darkly comic drama is set in the Hollywood Hills. It tells the story of four miserable, self-destructive bachelors, each of whom is pursuing careers in the film industry. They don’t seem the ambitious types, however. The bachelors (Eddie, Phil, Mickey, and Artie) spend their time drinking, womanizing, and ingesting a shocking amount of cocaine. All the while, Eddie - the central character - wonders why his life is slowly rotting away to nothing. The Male Characters Eddie:It is debatable whether or not Eddie and his cohorts learn anything by the conclusion. But the audience gets the picture: Don’t be like Eddie. During the play’s beginning Eddies spends his morning snorting cocaine and eating slightly molded Hostess Snowballs. Eddie desires a steady romance with Darlene (who sometimes dates his roommate). However, once he establishes a committed relationship, he subconsciously dismantles it with his paranoia. Eddie’s life is a ping-pong match, going from meaningless one-night-stand and drug binges to a â€Å"grown-up† life as an up-and-coming casting director. Ultimately, he is unhappy with both sides and takes solace in the belief that his friends are more pathetic than he is. But as he loses his friends, he begins losing the desire to live. Phil:Eddie’s best friend Phil is a fledgling actor and complete loser. During Act One, Phil can’t understand his own aggressive behavior. He verbally and physically abuses women, including the woman he marries and has a child with. As the play continues, Phil’s violence escalates. He picks fights with strangers, bullies his friends, and shoves a blind date out of a moving car! There are few redeeming qualities about Phil, yet he does achieve one sympathetic moment. In Act Two, he holds his baby daughter. As he shows her to his friends he wonders dreamily about her gaze and her smile. He says of children, â€Å"Yes. They are very honest.† It’s a touching moment - one that seems to hint that perhaps Phil will not continue down his dangerous path. Sadly, the hint deceives the audience. In Act Three, Phil’s character embraces oblivion, driving his car off Mulholland Drive. Artie:Artie feels slighted that he isn’t very close to Eddie. Every time he tells Eddie about his latest Hollywood pitch, Eddie is openly pessimistic about Artie’s chances. Yet Artie proves him wrong by finally getting a production deal. Artie’s personality also develops for the better. During Act One, he is as chauvinistic as Eddie and Phil. He finds a homeless teenager living in a hotel elevator. He takes her in, uses her for about a week, and then leaves her at Eddie’s house as a â€Å"present.† despite this disgusting behavior, Artie changes during Act Two after Phil treats his blind date, Bonnie, with such cruelty. Artie gains respect for Bonnie and, instead of using her as an object, he wants to spend time with Bonnie and her child at Disneyland. Mickey:Mickey is the most cold-hearted of the four men. He is also the most level-headed. He doesn’t share Eddie’s addictive behavior, nor does he rampage like the testosterone-driven Phil. Rather, he steals girlfriends from his so-called buddies only to break-up with the women days later. Nothing is terribly important to Mickey. When Eddie is desperately grief-stricken, Mickey tells him to simply get over it. When Eddie is faced with the death of a loved one, Mickey tries to convince him that it wasn’t such a loss. And when Eddie asks, â€Å"What kind of friendship is this?† Mickey replies, â€Å"An adequate one.† The Female Characters All the men treat the women characters so harshly it might be easy to mistake Hurlyburly as misogynistic. After all, the females are portrayed as drug addicts and willing objects of easily-won sexuality. (Which is a fancy way of saying they sleep with a guy five minutes after meeting him). However, despite their obvious flaws, the females in Hurlyburly are the savior characters. Bonnie offers insight and advice to the degenerative Eddie. She also gives Artie a glimpse of a â€Å"normal† sort of relationship, inspiring hope for a more balanced life. Darlene, Eddie’s somewhat serious girlfriend, is the least interesting character, but perhaps that’s simply because she has the most self-respect. All of the other characters are so demented, It’s easy not to notice the quirk-less Darlene, but she plays an important role as Eddie’s prime motive for a less destructive lifestyle. Ultimately, however, she has enough self-esteem to walk away from Eddie, thereby evaporating his motivation. Donna, the homeless teenager, accidentally makes the biggest positive impact. After wandering across California for a year, she returns to Eddie’s house. She arrives on the night Eddie is incredibly high and contemplating suicide. The girl has no idea that Eddie is experiencing these dark thoughts. Nonetheless, thanks to Donna’s philosophical speech about how she thinks the universe works, Eddie realizes that everything in the cosmos pertains to him, that he connected to all things, but it is up to him to decide what those things represent. Donna’s words calm him down, and the drug-crazed, less-than-zero Eddie can finally get some sleep. The question is: What kind of life will he wake up to in the morning? Note to Drama Departments As the character descriptions indicate, Hurlyburly is an intense drama featuring several challenging characters. Although high-school drama departments and family-oriented theaters should stay away from David Rabe’s play due to its language and subject matter, college departments and daring regional theaters should certainly check out this edgy play.

DQ #5 - Essay Example Lastly, the pie chart is important in showing the competitive position of a company against its competitors. Shares of companies in an industry are illustrated through pie chart as well as the contribution of sales among geographic locations. Misleading graphs becomes a problem in portraying the real situation. This is as worse as distorting the data set as these are both done in order to exaggerate and convey wrong information to the reader. The graph on the equity market posted on Yahoo finance (http://finance.yahoo.com/marketupdate/overviewu) is an example of a misleading graph. It should be noted that the Dow and Nasdaq markets are shown in two line graphs which uses different intervals. Also, the graphs are misleading because the horizontal axes did not start at zero making the movements in composite price indices appear very large even if this is not the case. This problem can be remedied by displaying the performances of Dow and Nasdaq on one graph. Also, the horizontal axis should start at zero in order to give investors an appropriate view on the changes in composite price indices. The use of focus group can be very helpful in gathering qualitative data especial

Crash Cultural Identity Assignment Essay Example | Topics and Well Written Essays - 500 words

Crash Cultural Identity Assignment - Essay Example The fact, that he was brave enough to fight with the guy, who tried to steal his car, became the evidence of the inner change, which had happened to Cameron. At the same time, it should be noted, that the characters put their cultural identity not only in their group, but they also want to be accepted and acknowledged in all cultural groups. On the other hand, the characters, who are supposed negative, as Ryan (the policemen, who has sexually assaulted Christine, Cameron's wife) or the attorney's wife Jean, being extremely impatient towards any other race except her own, also try to put themselves forward not only in their cultural group, but in others as well. Ryan not only wants to be the best among his co-workers, who are of Caucasian race, he also wants to show his superiority over other races, and thus make them understand his significance in terms of all races. The issue of cultural identity is shown to be manipulated through the scene in the attorney's office.

Residential broadband market overview Essay Example for Free

Residential broadband market overview Essay Limestone is a rock of which was once the bones and shells of sea animals. These died and collected as sediments at the bottom of seas, oceans and lakes. Chemical name: Calcium carbonate Chemical formula: CaCo3 Alternative names: Chalk, marble Limestone can be used to prepare a number of new materials. For this to happen limestone must undergo endothermic decomposition. Thermal decomposition is used on a large scale in industry to manufacture chemicals. When limestone undergoes thermal decomposition it produces Quicklime (CaO) Quicklime is produced in refractory-lined kilns. In most kilns, limestone is fed in at the top of the shaft and quicklime is drawn from the bottom. Air is blown in at the base and burns with fuels part of the way up the kiln. The products of combustion of the fuel is mostly carbon dioxide gas which escapes through vents at the top of the shaft. Various fuels are used e. g. coil, oil, natural gas and coke depending on the local fuel costs. The temperature created by these fuels reaches over 1000? C in the middle of the kiln. Most modern kilns produce up to 300 tonnes/day of quicklime. Most quicklime is sold as a granular product but there is a growing market for the finely crushed solid. Limestone is one of the worlds most common minerals. Because it is cheap and readily available it forms an important part of many other minerals. Once limestone has been converted to quicklime, the quicklime is used to form slaked lime. Slaked lime (calcium hydroxide) is made by adding a little water to quicklime. Powdered limestone:   Put in lakes to neutralize acids in the water Put on soil to neutralize acid soil. All rocks are made up of different minerals. In other words, minerals are the chemical constituents of rocks although you cant easily tell what their chemical composition is from their names. Sedimentary rocks are made of sediment formed when all other types of rock wear down (erosion) or break down because of the effects of weather (weathering). The particles of rock are transported by water or wind or ice to a low point on the earth (a sea or a valley). Gradually, over millions of years, they are converted to rock. The particles of rock form layers of sediment. Gradually more and more layers form on top of each other over thousands of years. The weight of the layers on top causes the bottom layers to be pressed together or compressed so the particles fuse together. This is called CEMENTATION. Over millions of years the layers of rock build up into what are called strata. Particles can be rubbed of sedimentary rock because it is the softest type of rock. Different sized particles form different kinds of rock. Very fine particles like mud form mudstone. Larger grains like sand form sandstone. Gravel and pebbles form conglomerates. Sedimentary rocks like Shale can be formed under the sea also. The shells from millions of tiny marine animals can build up on the sea floor. These shells are made from calcium carbonate. When these shells become slowly compressed together they form the rock limestone. When acid is added to this rock, it fizzes. As sediments collects, the bodies of plants or animals fall into them. The bodies become buried and gradually turn to rock as there is no oxygen gas to allow them to rot. Over millions of years these bodies turn into fossils. Fossils are only found in sedimentary rocks. When liquid rock is beneath the surface of the earth it is called magma, but when it comes out of the ground it is called lava. When they cool, they become solid and form the rocks we call igneous rocks. Magma and lava are made up of compounds called silicates. They are made from the elements silicon and oxygen, as well as other elements like aluminium and magnesium. As the liquid rock cools it forms crystals. The size of the crystals depends on how quickly it cools. Granite is formed when magma cools slowly under the ground so it has large interlocking crystals. This is called an intrusive igneous rock. When lava is erupted from a volcano it cools rapidly in the air so it has small interlocking crystals. This is called an extrusive igneous rock. An example of this type of rock is basalt. The structure of existing rocks can be changed by contact with magma or great pressure from underground. When this happens, the rock is said to have metamorphosed. (This just means changed. ) Any kind of rock can metamorphose. Clay and Shale (which are sedimentary rocks) can be changed by pressure until they become slate. This allows the slate to be split into layers easily. This is one reason why slate can be used for roofing material. If slate is then heated even more and put under more pressure it forms a rock with bands of interlocking crystals. This rock is called Schist. Limestone is turned into marble when the high temperatures underground break up the shells and they then reform as smooth, hard crystals. Scientists think ha the earth has been in existence for about 4500 million years. In the beginning, the surface was liquid, but gradually it cooled enough for a solid crust to form. (About 3700 million years ago). The earth has had an atmosphere of gasses since it was formed but the types and amounts of each gas has changed. The earths crust is much thicker under the continents than under the oceans. Continental crust is about 40km thick compared to 10km for the crust under the oceans. Below the crust is a semi-liquid area called the mantle. The centre of the earth is called the core and it is made of the metals Iron and Nickel. Because different parts of the earths crust are moving slowly in different directions, huge stresses and strains are set up. These can cause the rocks to become tilted, folded (bent) or faulted (split). They may even be turned upside down. Sedimentary rocks are softer than other types of rocks and fold more easily when compressed (squashed). If this happens on a large scale, then Fold mountains like the Alps or Himalayas are formed. A downward dip or fold is called a Syncline and an arch is called an Anticline. Brittle rocks fracture (fault) under stress. The earths crust is not a continuous layer but is made up of many separate units called Tectonic Plates. The plates move by convection currents in the molten rock of the Mantle. This moves the plates very slowly at the rate of a few centimetres a year. Over millions of years the continents have separated to reach their present positions. When an oceanic plate moves below a continental plate, the rock gets very hot and melts to form Magma. This then reaches the surface in Volcanoes. Also, where the oceanic plate moves downwards, a very deep area of sea floor is formed. These types of areas are called Ocean Trenches. Formation of coal and oil: In the carboniferous Era, which lasted 65 million years and ended 280 million years ago: The British Isles was on the equator. The land was tropical forest. Coal was made from dead animals and plants. The plants did not rot because they got covered in mud so no oxygen could get to them. The coal seams were formed by weight of new deposits squashed the tree layers into thin seams. Coal was formed 280 million years ago. Fractional Distillation: When oil is pumped from the ground it is as a thick, black, foul smelling substance called Crude Oil. It is a mixture of chemicals called hydrocarbons. A mixture is just a mix of chemicals. The many hydrocarbons in crude oil may be separated into individual chemicals called Fractions by a process called Fractional Distillation. Crude oil is a mixture of Hydrocarbons. They can be separated by putting the oil into a fractioning column. The crude oil is heated on its way into the column so that the oil is evaporated. This turns the liquid into a gas. The vapour then moves into the column. The chemicals with the least/most?molecules (more carbon atoms) move to the top e. g. petrol. As the molecules become heavier, their boiling points increase. Once at the correct temperature the vapour condenses to a liquid and is run off. Crude oil contains most fuel and bitumen yet we do not need it all. We need lots of petrol (which contains 5-10 carbon atoms) but we have too much fuel oil etc. (over 70 carbon atoms), so what we do is this. We break up large useless molecules to make small, useful molecules like petrol by a process called cracking. Paraffin is a general name for a group of long hydrocarbons used as fuels. If mixed with pieces of porous porcelain as a catalyst, it can be made to undergo thermal decomposition or cracking. Porous means lots of holes, which gives a large surface area. Thermal decomposition means breaking something down with heat. Fractional distillation of petroleum (crude oil) produces different products because petroleum is a mixture of hydrocarbons. The compound in each fraction have similar boiling points. The fractions with higher boiling points tend to contain molecules with more carbon atoms. These bigger molecules are long chained and have larger molecular masses. When these are burnt they produce sooty flames. They are very viscous (syrup-like). As a result there is high demand for smaller molecules and less demand for these massive molecules. The oil industry tries to balance the problems of supply and demand by converting the less saleable fractions into saleable fractions. The main way in which this is done is by the process known as cracking. The reactions are usually carried out at high temperature using a catalyst. We have seen that when large hydrocarbon molecules are broken open, or cracked, they produce smaller molecules like Ethene. It is possible to join lots of Ethene molecules together to form a type of plastic. Simple building blocks like the paper clip (or Ethene) are called MONOMERS. When they are made into a long line of units we call it a POLYMER. The process which converts lots of Monomers to a Polymer is called PLYMERISATION. Common polymers include plastics, fibres and rubber. The elements present in Ethene monomers are hydrogen and carbon. What happens to convert monomers to polymers? Double bond breaks open during polymerisation. The name of the polymer made from Ethene is polyethene. Polyethene is more commonly known as polythene. Another type of plastic is called Polyvinyl Chloride PVC for short, is strong, hard and less flexible than polythene. It is used to make pipes, guttering and electrical insulation. Combustion is another word for burning. Burning is a chemical reaction in which materials react with heat. The equation for burning is: Fuel + oxygen = CO2 + water + energy. If there is not enough oxygen in the air, the fuel dies not burn fully and the poisonous gas Carbon Monoxide is formed. Several people are killed each year due to poisoning by carbon monoxide from badly ventilated gas fires. Some fuels also contain Sulphur e.g. Coal. When this burns, it produces the gas sulphur dioxide. Sulphur + oxygen = sulphur dioxide. When this gas dissolves in rain, it produces acid rain. Waste gases from the exhausts of motor vehicles are also released into the atmosphere. They are also responsible for making the rain acidic and they pollute the air. Oxygen gas is:   Colourless and odourless   Molecules are diatomic   Approx. same density as air.   Essential for combustion and respiration   Reacts with most metals and non-metals to form oxides. Test for glowing oxygen = glowing splint re-lighting. Oxygen is a by-product of photosynthesis. Oxides can be acidic, basic (alkaline) or neutral. The link between the terms alkali and base is that an alkali is a base which dissolves in water. Non-metals form acidic oxides. Metals form alkaline oxides. Many metals and non-metals are found as oxides in the earths crust. They are called ores. When elements react with oxygen it is called oxidation. During respiration and combustion, oxygen is used up and carbon dioxide is released back in to he air. All of the air is not used up because plants use up the carbon dioxide and release oxygen when they make their food by photosynthesis or respiration? This process has been happening for thousand of years. However, in the last 200 years, the amount of carbon dioxide in the atmosphere has increased because:   There are many people on earth.   We have burned millions of tonnes of fuel   We have cut down thousands of square miles of forest. The carbon dioxide is acting like a blanket around the earth and it is trapping the heat from the sun, which leads to a raising of the earths temperature. This is called the greenhouse effect. Acid rain is made when acid gases dissolve in rain. Carbon dioxide is made when carbon burns in the oxygen in the air. When coal is burned it releases the gas sulphur dioxide. This also makes acid rain because it dissolves in rain to form sulphuric acid. Inside car engines, the temperature is hot enough to make nitrogen and oxygen join together to make nitrogen oxides. These dissolve in rain to make nitric acid. When acid rain falls on the earth it has the following effects: Stonework on building is dissolved and crumbles away   The water in rivers and lakes becomes too acidic so plants and animals die You could reduce the acid level in rivers and lakes by putting limestone in it. The gases in the atmosphere originally came from volcanoes. The gases produced were carbon dioxide, hydrogen chloride, argon etc. There is not hydrogen left in the atmosphere because it was so light it evaporated and escaped. Distillation of oil: 1. Vaporisation the thick oil is heated to from vapour/gas 2. Separation lighter molecules move upwards and heavy molecules sink. Lighter molecules move upwards to the coolest region at the top. There is a temperature and density gradient. 3. Condensation the vapour is cooled to form a liquid (or solid).

F. Scott Fitzgeralds The Great Gatsby :: essays research papers

During Fitzgerald's The Great Gatsby, it is apparent to be an absurd time for the wealthy. The shallowness of money, riches, and a place in a higher social class were probably the most important components in most lives at that period of time. This is expressed clearly by Fitzgerald, especially through his characters, which include Myrtle Wilson, Tom and Daisy Buchanan, and of course, Jay Gatsby. This novel was obviously written to criticize and condemn the ethics of the rich.   Ã‚  Ã‚  Ã‚  Ã‚  The first character who represents the shallowness of the wealthy is Myrtle Wilson, even though she is not wealthy at all. She seeks to escape her own class and stoops to the low point of betraying her trusting husband who loves her more than anything. Her attempt to break into the higher class that Tom belongs to is doomed to fail. Even though she does take on Tom's way of living during their affair, she only becomes more vulgar and corrupt like the rich. She scorns people from her own class and loses all sense of morality. Myrtle never finds a place in Tom's higher social division, and what reveals her impertinence most is that she thought she would succeed in the first place, giving up all her morals for the wealthy.   Ã‚  Ã‚  Ã‚  Ã‚  Undoubtedly, Tom and Daisy Buchanan exceedingly demonstrate the wealthy class's lack of integrity. Their lives are filled with material comforts and luxuries and completely empty of true purpose. Daisy's lament is especially indicative of this: 'What'll we do with ourselves this afternoon? And the day after that? And the next thirty years?'; Daisy also exhibits her shallowness when she is too restless to wait for her 'love', Gatsby, to return from he war, and she marries Tom. Her most drastic immoral action is committed when she runs over Myrtle and does not even bother to stop and help a person that is 'below' her. Daisy's husband, Tom shows his ridiculous morality in different ways. One way is his search for power, which is shown most through his affair with Myrtle and his possessiveness. He evidently feels further domination and masculinity when he has her, a woman of lower class, as his mistress. Secondly, Tom Buchanan is shallow enough to think that everything and everyone he has in his life are part of his property. This increases his 'power' and makes him feel as if he is truly successful. This couple, Tom and Daisy certainly contain serious corruptness due to their shallowness and self-indulgence. F.

Comparison of a traditional book store and an online book store This is a traditional bookstore, operated by a traditional Hierarchical structure. The quantum of work involved is more and hence a relatively higher number of employees are employed. The information flows from the top level to the bottom level through paper correspondences or mail communications.These shops are slow in adapting to the market changes. The stocks are usually built and maintained based on the market forecasts. Hence, this type of stores usually carries a large inventory and hence requires a lot of space. This has a direct impact on the financial overheads. The book stores like â€Å"Barnes & Noble†, â€Å"Amazon† or â€Å"Border† are online bookstores since 90’s. They are E enabled business concerns.

Character Analysis of Aminata: Book of Negroes Essay

The Book of Negroes by Lawerence Hill started as a story of the capture of a West African girl and her journey to become a slave. Her traumatizing experience was written with a desperate tone that was achieved through the use of literary devices such as metaphors and alliteration. Emphasis was put on the conflict between Aminata and society which helped to develop her as a hopeful character. â€Å"We walked for many suns, growing slowly in members, lumbering forward until we were an entire town. Each time, people swarmed out to stare at us. Initially, I believed that the villagers were coming to save us. Surely they would oppose this outrage. But they only watched and sometimes brought out captors roasted meat in exchange for cowrie shells and chunks of salt. Some night when they had us lie down in fields, our captors paid village women to cook for us-yams, millet cakes, corn cakes, sometimes with a bubbling peppered sauce. We ate in small groups, crouching around a big calabash, spooning out the hot food with the curved fingers of our right hand. While we ate, our captors negotiated with local chiefs. Ever chief demanded payment for passage through his land. Every night, our captors bartered and bickered well into the evening. I tried to understand, in the hope of leaning something about where we were going and why† (p. 34, Hill). In this quotation, Aminata’s journey is described with a bleak and demoralizing tone. The journey of Aminata and her hostages lasted â€Å"for many suns† and wore down their hope for freedom and their faith in humanity. The hostages continued â€Å"lumbering forward† as â€Å"an entire town of kidnapped peoples,† with no hope of being saved. When â€Å"people swarmed out to stare at us †¦ e initially believed that the villagers were coming to save us. † Eventually the captives realize that the people are only interested in making exchanges with their captors. This leaves the hostages with the forlorn realization that no one would make an attempt to liberate them. The captives were demoralized further when they â€Å"crouched around a big calabash, spooning out hot food with the curved fingers of our right hands. † As captives, the native West Africans were treated as less than human. Like animals, they were forced to gather around a bucket of food and eat without tools. The lack of respect and dignity given to the captives corrupted their sense of self-worth until there was little left but the instinct to survive. Literary devices are a key element in setting the tone of this novel. As the captives were continuing they were â€Å"slowly growing in number†¦ until we were an entire town of kidnapped people. † This metaphor emphasizes the number of prisoners the captors have taken hostage and that the group goes far beyond Aminata. It also emphasizes the amount of power the captors have other the captives. Even though the captives outnumber the captors, the captors are still capable of preventing any rebellion and power within the hostages. Another literary device that highlights the hopeless situation of the captives is parallel structure. On their journey they â€Å"passed village after village, and town after town. † The us of parallel structure creates a sense that the journey of the slaves is perpetual and induces the feeling that the slaves are stuck on a ceaseless journey. This also contributes to the hopeless mood of the novel; with no end in sight the slaves find little to look forward to. Although the captives lose hope in their future, Aminata manages to keep a part of herself hopeful and this is essential to her characterization. Aminata knows that there is a very small chance of escaping, but she also knows that if she has more knowledge of the captor’s plans, she has a better chance at freedom: â€Å"Every night I heard the captors barter and bicker well into the evening. I tried to understand, in the hope of learning something about where they were going, and why. † This also demonstrates her thirst for knowledge. Growing up Aminata strived to learn reading and writing and any other skills she could. She does not let go of this part of herself even in her futile situation. As well as being hopeful and clever, Aminata proves to be innocent and naive. While travelling through villages she believes â€Å"the villagers were coming to save us. Surely they would oppose this outrage. † But Aminata eventually realises that the villagers are not interested in freeing the captives. The only concern the villagers have is to make deals with the captors. Her ideals, that the people of her country would band together to bring a stop to their exploitation, are crushed and strips her of her innocence on her journey to slavery. Aminata finds herself in many conflicts with many different elements. One example is the conflict between her and society. Society viewed Aminata and her fellow prisoners as less than human and with little value. The slaves were treated like animals, â€Å"people swarmed out to stare at us†. They are seen as another species and not as people with intelligence and skills. But contrary to the beliefs of the society, Aminata is an intelligent and skillful girl whose thirst for knowledge is never put to rest. She continues to try â€Å"to understand the chiefs, in the hope of learning something. She also knows how to read and write which is considered extremely valuable in her culture. But because society views slaves as non humans who are not capable of being intellectual, Aminata’s capabilities are not seen by others and she is continual seen as an inferior. The Book of Negroes tells a story about the degrading experience many had to go through because they were seen as inferior. This degradation is apparent through the demoralizing and bleak tone. But Aminata manages to keep hope and a clear head and provide a beacon for herself and others around her. She continues to expand her horizon of knowledge and aspire to better herself. Although she is faced against the power or society, Aminata holds strong to herself and carries on. Her story is told with the use of literary devices such as parallel structure and metaphors to emphasize the desperation and inadequacy of her journey. She manages to look past all the horrors that surround her and hope for a better future, and perhaps with her strong will and knowledge she will achieve this someday.

Agroclimate Factors of Oil Palm in Nigeria

Agroclimate Factors of Oil Palm in Nigeria EFE S. I. AWARITEFE O. D. ABSTRACT . Using multiple correlation analysis and student ‘t’test, the Agroclimate factors of Oil Palm production was examined for ten years periods. Result showed that Agroclimate factors (sunshine, temperature and rainfall) are highly correlated with oil palm yield. This is evident from a multiple correlation of 74%. It was also observed that oil palm yield is more in the dry season than in the wet season. INTRODUCTION Any agricultural system is a man-made ecosystem that depends on climate to function just like the natural ecosystem. The main climatic elements that affect crop production are solar radiation, temperature and moisture. These climatic parameters and other depend on them, largely determine the global distribution of crops yield and livestock (Ayoade, 1993). He stresses further that climate elements exert an influenced on all stages of the agricultural production chain, including land preparation, sowing, crop growth and manageme nt, harvesting, storage, transport and marketing. This view has earlier be noted by Oguntoyinbo (1983) when he attributed the donation of the cocoa and kola-nut belt in southwest, oil palm bush in southeast and the north south ridge of river Niger comprising area of groundnut, cotton and rice cultivation to these climate vagaries. However, climate influence on oil palm has attracted the attention of some scholars over the years. Amongst whom are Manning (1956), Broekman (1963), Oshodi (1966); and Hartley (1988). An examination of their views shows that Manning (1956), outlined the rainfall requirements of selected food and commercial crops grown in West Africa, and he opined that the mean annual rainfall for oil palm is between 1500— 3000mm in West African Countries. Devuyst (1963) correlated oil palm yield with the influence of rainfall alone; using the concept of useful rainfall. His work however showed a positive correlation. He regarded rainfall as the sole agent influenc ing oil palm yield, and consequently considers any yield maxima to originate in wet season. Broekman (1963) accepted the view of Devuyst but differs in his finding. He stressed that dry season rainfall is positively correlated with oil palm yield. To him, it is reasonable to except that the amount of rainfall during the dry season will be of particular importance, as moisture is a limiting factor during this period. On the other hand, Oshodi (1966) computed the effective growth energy index for some selected crops in Nigeria. The index was however based on only temperature and rainfall. The Effective Growth Energy (E.G.E) for oil palm in Nigeria is 250-300Â °F. Harley (1988) stated that oil palm yields are correlated with dry season rainfall with measures of effective sunshine, which take into account the distribution of such rainfall in’ the dry season. It is clear from the foregoing that rainfall and temperature correlation with oil palm has been substantiated, however, th e relationship between sunshine and oil palm yield, as well as the joint contribution of sunshine, rainfall and temperature, has not be substantiated. Similarly there are divergent views on the relationship between the seasons and oil palm yield. Also, since the establishment of Nigeria Institute for Oil Palm Research (NIFOR) in 1939 there have been a relative neglect in the development of Agroclimatological Research Unit in the institute. While other research units (Agricultural Economics, Agricultural Engineering Research, Agronomy, Biochemistry, Chemistry, Extension and On-Farm Adaptive Research, Entomology, Plant Breeding, Plant Pathology, Plant Physiology and Statistics) have been developed. What exists in that unit is a dilapidated weather station where climate data’s are collected and never used for research purposes. So, the present study of Agroclimatic factors of oil palm yield in Nigeria is borne out of the desire not only to fill the above gaps, but to proffer use ful suggestion that will guide both the oil palm farmers, and the NIFOR officials on the need to plan with the climate of the area. Therefore, the aim of the study is to examine the extent to which temperature, sunshine and rainfall correlate with oil palm yield.

What is a Theoretical Approach Coursework Example | Topics and Well Written Essays - 1250 words

What is a Theoretical Approach - Coursework Example However, even if the philosophical topic is a changeable topic that cannot be sufficed by the formation of theories that try to explain such broad and complex concepts, formation of a comprehensive and all inclusive theoretical framework can give us an explicit way to aid in tracing and identifying any territory of philosophy. This would further increase our understanding of philosophical concepts, which are purported to be beyond human understanding (Costa, 2002). A theoretical approach refers to an organized set of principles put forward by an interested party in the study of a topic of interest put bring forth their conceptualization of a matter of importance. This theoretical approach must follow a given methodological approach to put it in the required context to further understanding. A prescriptive theoretical approach aims at explaining what a concept under study should be. It outlines definitions in order to give concept under study meaning that can be used to further unders tanding. This approach is not concerned about past events but focuses on the future to guide an analysis. A descriptive theoretical approach aims at explaining what philosophy has been by looking at the past.... Aristotle can indeed, be considered a theorist given the numerous contributions in philosophy through theories highlighted in his book, Nicomachean Ethics. Aristotle contributed greatly in the explanation of concepts of human lives jointly with other theorists such as Plato (Ackrill, 1981). The theorist presented ideas on matters that pertains happiness sequentially to bring comprehension of the origin and other dynamics of happiness. According to Aristotle, happiness was reliant on individuals instead of other people around humans. Aristotle presented critical thinking concerning the pursuit of happiness in the world. Aristotle modified and incorporated observations concerning happiness thus presenting the intricate and reasonable theory concerning happiness. Aristotle utilized or presented intricate situation in his works as a theorist using skill and comprehension of concepts in order to develop ideas that were applied in formulating theories (Ackrill, 1981). The situation that Ar istotle structured in order to come up with the theories in philosophy and other fields were meant to serve a clear purpose within the contexts of the structured theories. In various works presented in the book, Nicomachean Ethics, certain ideas or concepts offered by Aristotle were never immediately important although other relevant ideas got presented by other theorist in response to either add on or deduct irrelevant ideas. Aristotle developed ideas that he presented in his works, through stepwise methodology, to ensure that the problems that were presented go solved perfectly although it is not certain that the ideas were facts or fiction. Aristotle can
