Parkinson disease - Research Paper Example Usually, the nerve cells that degenerate because of Parkinson’s diseases are those located in the basal ganglia. In addition, Parkinson’s disease contributes to the loss of nerve cells in the substantia nigra, which is a component of the brainstem (Carranza 2013, p. 67). Worth noting is the fact that the cells affected by Parkinson’s are responsible for the production of dopamine, which is a critical neurochemical messenger playing a key role in coordinating normal movement. Usually, dopamine forms the start of a circuit of messages responsible for the functionality of normal movement. Unfortunately, Parkinson’s disease affects nerve cells that produce dopamine reducing the level of stimulation in the receptors involved in the coordination of normal movement. More specifically, the receptors in the basal ganglia circuit fail to undergo active stimulation resulting in challenges in movement. Patients with this disease, suffer from movement with tremors, los s of balance, stiffness, as well as slow moving. This paper will describe the signs and symptoms of Parkinson’s disease, as well as the current treatments used in treating the disease. As highlighted above, Parkinson’s disease causes the degenerations of neurons. However, researchers have been unable to describe the specific reason or cause that triggers the degeneration of neurons. The degeneration of neurons remains to be an area of interest or many researchers who understand the social effects, as well as the economic implications of the disease. In addition, the progression of the diseases can be highly debilitating denying an individual the freedom to move around or have a proper body balance (Chaudhuri 2009, p. 78). Evidently, the past few years have seen many researchers make remarkable progress in understanding the disease. Acceleration of such understanding has helped manage the condition of many patients with the disease. Current

Who have to deal with loss Essay Example for Free

Who have to deal with loss Essay These shoes are a symbol of the daughter, One shoe pointed in fact towards the bedroom window and the other pointed towards the door. They wanted to get out The writer has used personification here to suggest how the mother is trying to figure out why her daughter has left her, just like in Chemistry where the narrator misunderstands the mothers motives to set out for a new life. The boy mistakes this look of relief, as if she had recovered from an illness. As if she did not care about the grandfather. The mother in Your Shoes makes the reader sympathize for her. In this way, we see how the character of the mother is presented in the manner she deals with loss. The shoes are abandoned and this suggests that these shoes are a metaphor of the rejected parents. In comparison the structure that both the writers have used are that the stories are written in non- chronological order. In Your Shoes the mothers thoughts flit backwards and forwards the mother does not deal with her loss and neither does she come to terms with it. Just like in Chemistry although the boy witnessed a lot he does not share his feelings. It is clear when Mother said: Hes only ten what can he know? the boy certainly knows a lot more than he is credited for. Furthermore the stories Your Shoes and Chemistry are both written from the 1st person which then only shows the thoughts of the main characters so the readers may have to work out for themselves how the characters feel although it is fairly obvious in Your Shoes. In this way, we see that the writers have presented the way the characters deal with their losses differently. The themes explored in both stories is conflict as in Your Shoes the father deals with the situation by calling his daughter a dirty slut and actually makes the situation worse, which is equal to Chemistry where the grandfather comes between Ralph and the mothers relationship. The theme of change is also mentioned in the stories as the mother is not prepared to face anything different, Ive taken a weeks sick leave from school she does not want to go back without her daughter, but instead she wants everything back to how it was. Whereas the boy in Chemistry is perhaps not ready but is forced to change the way he lives. The ways these characters deal with loss differ greatly. The setting in Your Shoes is of the mother lying curled up in the middle of the bed here the mothers surroundings reflect the presence of her daughter. The mother is almost like a foetus, weak and unable to look after herself. The room symbolizes her daughter just like her shoes. In contrast the setting in Chemistry symbolizes the relationships drifting apart between each generation, she had grown neglectful of Grandfather. Here Swift is describing the invisible thread that is holding the family together is shifting. The setting in these stories symbolizes how the characters in each story deal with loss. The setting in these stories symbolizes how the characters in each story deal with loss. To conclude I think that the main difference between the stories Your Shoes and Chemistry is that the mother does not come to conditions with the way she deals with loss. Whereas in Chemistry the boy realizes that dealing with loss is part of your life.

Diseased Body in Wuthering Heights Essay Example for Free

Diseased Body in Wuthering Heights Essay In Wuthering Heights by Emily Bronte it can be viewed that there is â€Å"more suffering caused by a diseased mind than by a diseased body.† The idea of a â€Å"diseased mind† is a mental illness or madness and the â€Å"diseased body† is a physical illness or injury, both of which are displayed by many characters in Wuthering Heights. Heathcliff is a prime example of a character with a â€Å"diseased mind† that causes him suffering. He spends the majority of his life contemplating and acting out revenge towards Hindley and the Lintons because he believes it was their fault Catherine thought it would â€Å"degrade† her to marry Heathcliff, even though she loved him; this is one example of his unstable mind set. In chapter 9 Nelly foreshadows the suffering of Heathcliff by saying â€Å"if you [Catherine] are his choice, he’ll be the most unfortunate creature,† this is because Nelly understands that society wouldn’t accept the pair to marry, therefore Heathcliff will be unfortunately heartbroken. Heathcliff believes that Catherine is a part of him: â€Å"I cannot live without my soul,† he says which highlights that he is suffering without her. It is from this heartbreak and suffering that his â€Å"diseased mind† commenced. Heathcliff’s â€Å"diseased mind† heightens when he asks for Catherine to â€Å"haunt† him when she is dead; haunting is an element of the Gothic genre but the madness of Heathcliff is enhanced when he requests that Catherine drives him â€Å"mad.† The word â€Å"mad† is ambiguous in this quotation because it could be viewed that Heathcliff wants to be haunted until he is angry with Catherine so he can destroy his love for her. An alternative view is that Heathcliff wants to be haunted until he is insane and suffering since he is desperate to see Catherine, this becomes true because after Catherine’s death Heathcliff’s mind is haunted by his love for her. Jerold E. Hogle explains this is accurate because characters in Gothic novels are â€Å"haunted psychologically† and this is accurately shown through the character of Heathcliff. His mind is â€Å"diseased† by his separation from Catherine due to her choice of partner and her death, which causes him and everyone in the novel immense suffering because of his vengeance. Heathcliff’s unconditional love causes Catherine’s â€Å"melancholy† â€Å"mental state† because it is overwhelming and she is in love with him but a  Victorian society wouldn’t accept their relationship because of the Heathcliff’s very low class, which would result in them being â€Å"beggars.† Catherine has â€Å"a peculiar expression arising from her mind set† before she tells Heathcliff â€Å"you have killed me,† this highlights her â€Å"diseased mind† and the suffering it is causing her because she hasn’t died yet but it could be interpreted that she feels as though she has which emphasises her suffering, but also her madness. The â€Å"peculiar expression† that Catherine is described to have could be because she was â€Å"thinking†¦ of Wuthering Heights.† The â€Å"expression† could be interpreted as a smile, which would be â€Å"peculiar† to Nelly because she has been depressed living with Edgar, therefore a smile would be unusual; David Punter explains â€Å"Gothic reminds us we are driven by our passions† and Catherine’s passion is Heathcliff, which would explain her â€Å"expression† when thinking about Wuthering Heights. This idea of Catherine’s thought process in her â€Å"diseased mind† emphasises her pain and suffering because she cannot be without Heathcliff, her â€Å"soul,† yet she is continuously thinking about him, this is essentially what drives her insane. Catherine’s mental suffering is closely linked with her physical suffering which is an example that represents the â€Å"diseased body† in Wuthering Heights. Another character with a â€Å"diseased body† in Wuthering Heights is Isabella, whose â€Å"bruised† body is a valid example of suffering. Heathcliff’s â€Å"diseased mind† causes him to abuse Isabella which leads to her suffering and her injured body

Childrens Learning :: Language Learning Essays

Linguistics is the scientific study of language. It endeavours to answer the question – what is language and how is it represented in the mind? Language is a system of symbols and rules; exclusive in its form to human beings that enables us to communicate. Symbols are things that stand for other things: words, either written or spoken, are symbols and the rules specify how words are ordered to form sentences. Language symbols are arbitrary, with no necessary connection between the symbol, be it word or gesture, and the object or idea to which it refers. For example, if one wanted to construct a new word for ‘tree’, they could use almost any legitimate combination of sounds that are not already being used for other purposes. However, symbols must be used systematically for effective communication to occur. The arbitrary symbol system must be shared; for communication to take place at least two people must have access to the system. There are a number of dimensions to language acquisition and development and each stage occurs chronologically. These are as follows:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Phonology – study of the sound patterns of language. It is concerned with how sounds or ‘phonemes’ are organised and examines what happens to speech sounds when they are combined to form words and how these sounds interact with each other. It endeavours to explain what these phonological processes are in terms of formal rules.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Semantics – is our knowledge of word meanings and how we acquire vocabulary. The semantic component is made up of morphemes, the smallest units of meaning that may be combined with each other to make up words. For example, the word ‘paper’ and ‘s’ are two morphemes that make up the word ‘papers’.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Syntax – syntax is the study of sentence structure. It attempts to describe what is grammatical in a particular language in terms of rules. These rules detail an underlying structure and a transformational process. The underlying structure for English, for example, would have a subject-verb-object sentence order (‘James kicked the football’) and the transformational process would allow an alteration of the word order, which could produce something like ‘the football was kicked by James.’ The syntactic component consists of the rules that enable us to combine morphemes into sentences. As soon as a child uses two morphemes together as in ‘more juice’, he or she is using a syntactic rule about how morphemes are combined to convey meaning.

Comparing and Contrasting the Sublime Essay -- Williams Shelley Trave

Comparing and Contrasting the Sublime What can be said about the sublime? Class discussion led to the definition of sublime as the element found in travel literature that is unexplainable. It is that part of travel literature where the writer is in awe of his or her surroundings, where nature can be dangerous or where nature reminds a human being of their mortality. The term "sublime" has been applied to travel texts studied in class and it is hard not to compare the sublime from texts earlier in the term to the texts in the later part of the term. Two texts that can be compared in terms of the sublime are A Tour in Switzerland by Helen Williams and History of a Six Weeks' Tour by Mary Shelley and Percy Bysshe Shelley. There are similarities and differences found in both texts concerning individual perspectives of travel and the sublime. The main focus of this commentary will be comparing and contrasting the perspectives of Williams and Shelley within their respective texts, the language of the sublime and the descriptio ns of the sublime. Both Shelley and Williams write from a personal perspective. Both travel to and make observations on the area that interests them. Williams travels to Switzerland while Shelley travels through Geneva to Chamonix. In the introduction of Williams's text she immediately reveals the reason why she wishes to visit Switzerland while Shelley assumes that the reader recognizes that he is a traveler who wants to go from point A to point B. Williams's introduction reveals that she has already dreamed about what it would be like to visit Switzerland and she shares with her readers that 'I am going to gaze upon images of nature; images of which the idea has so often swelled my imagination, but whic... ...ering more leeway to understanding the sublime. On a more personal note, comparing how Williams and Shelley write about the sublime has made the idea more clear in my mind on how to approach readings that contain the sublime, it is much easier to understand and furthermore, it offers more than one way of looking for and at the sublime.

History Of Hockey Essay -- essays research papers

For more than a century, hockey historians have found that precisely tracing the sports origin is not only a difficult task but, a virtual impossibility. Therefore I can only try to deduce for myself, from the records, claims, and accounts, which are available to me, when, where, and by whom the first ice hockey was played. I’ll also discuss the early problems and obstacles that the NHL encountered. Plus I will also tell a little bit about early equipment, along with early game play and ice conditions that players encountered. Lastly, the Stanley Cup, which is the most prized and oldest sports award of the NHL. It has been won many times, by many different teams. Ice hockey is traceable to games played on fields as far back as nearly 2500 years ago. In 478 BC, a Greek soldier, Hemostocoles, built a wall in Athens which contained a sculpture scene portraying two athletes in a faceoff-like stance holding sticks similar to those later used in field hockey. (Hubbard & Fischle r, page17) Perhaps native Americans were the first to play hockey like games. The Indians of Canada invented the field game lacrosse, which is known by the legislative act as Canada’s and national sport. The Alogonquins who inhabited the shores the St. Lawrence River played an ice game that was similar to lacrosse called "baggataway," played without skates and with an unlimited number of participants. French explorers who visited the St. Lawrence River area and northern areas of United States in the 1700’s witnessed these matches. (Hubbard & Fischler, page17) According to the dictionary of language of Micmacs Indians, published in 1888, the Micmacs of eastern Canada played an ice game called "oochamkunutk," which was played with a bat or stick. Another ice game played by the Micmacs was "alchamadijik," which was referred to in legends of the Micmacs, issued in 1894. (Hubbard & Fischler, page18-19) Early hockey-like games that came from across the Atlantic include the Field game Hurley from Ireland, field hockey from England, and the ice games English bandy and Kolven from Holland. Hurley is a ground game that is still popular in Ireland. It was originally played by an unlimited number of players representing one parish against another. A flat field hockey-like stick and a large ball were used. Irish immigrants, who came to work on the Shubenacadie C... ... to an end. 1918-19, The NHL continues to suffer bad times in the second season. Crowds remained sparse, even though the league tried to elict interest by adopting new rules to make the game faster and more interesting. During this season an very unusual thing had happened, for a first time ever the Stanley cup was not awarded, the reason why it was not awarded is because Canada was in the midst of a lethal flu epidemic in the which touched the a Stanley cup teams. The flu sent many players to the hospital, tragically some of them died 6-8 weeks later. Therefore the competition was held off and a cup of was not awarded. Never again has the Stanley cup not been awarded after post season. (Hubbard & Fishler, page 55-68) Over the years the NHL suffered similar obstacles, financial problems, wars, and the lack of fans, to about the 1924-25 season. After that season times started to become easier. More profit was being made by the owners, and more fans were attending the games. Ho ckey was becoming one of the most popular sports in all of Canada, which quickly spread to the U.S. Nowadays hockey is one of the most profitable and enjoyable sports throughout North America and Europe.

Essay --

Although many factors have influenced the development of civilizations around the world, most are derived from the necessities required by all humans to maintain existence. One of the most primitive needs of the human race is food. The ability of the land to provide a surplus of food was a significant contributing factor for civilization to emerge in Mesopotamia. Crops such as barley, emmer, olives, beans, grapes and flax were very easy to grow in the fertile soil found there. As more people began to arrive and settle in Mesopotamia, towns began to emerge building a civilization that encompassed various workers, organization, and cooperation among the people. The Mesopotamians learned to reroute would be floodwaters to the drier land to hydrate their crops, laying the foundation for modern day irrigation systems. Although there were areas such as Mesopotamia that had an abundance of food, other areas were not as fortunate. Many would have to travel to purchase food or obtain water. Traveling on foot could be very tiresome and demand lengthy trips. Another reason for the need of transportation of a method other than on foot was war. This led to the invention of the chariot, as early as 1800 BCE by the Syrians. As the steppe people migrated into established civilizations, chariots became more widely utilized as the preferred weapon. Rulers from areas widespread as Europe, China, the Middle East, and India utilized chariots as their master weapons. The use of the chariot eventually succumbed to horseback riding as the preferred method of travel. Just as societies and civilizations expanded over the continents of Europe and Asia ¸ the United States also expanded from the original colonies settled on the east coast to the ... ...arvests to pay their rent to be evicted. Many were shipped by their landlords to British North America on the hopes of empty promises of money and clothing. Although the ships landed in Canada, of the survivors, nearly half walked across the border into America deserting their mother country after the deception. Civilizations throughout the years have manifested through the need for change and survival. Whether food, resources, or the need for travel was the inspiration, people relocated to meet their own needs. Societies were established based on the cultures they came from, acculturated with the indigenous people they came in contact with. We all have needs to survive and provide future generations with the ability to progress forward. As the world changes, we learn to adapt and generate new technology as a means to ensure the maintenance of the human race.
