What is paresthesia Essay Example

What is paresthesia? Essay Paresthesia means abnormal sensation on the skin that has no apparent physical cause. The term originates from Greek: para = disordered; aisthesis = perception. The most common abnormal sensations are numbness and tingling. Types of Paresthesia Anesthesia means absent sensation or complete numbness. Hypoesthesia is decreased sensation or partial numbness. Hyperesthesia is increased sensitivity. Dysesthesia is abnormal sensation, such as tingling or pins and needles or ants crawling sensation. Hypoalgesia is decreased sensitivity for pain Hyperalgesia is increased sensitivity for pain Allodynia (Greek allos = other; odyni = pain) is sensation of pain caused by stimuli that usually do not cause pain Causes of Numbness and Tingling More than 200 causes of numbness and tingling are known. Permanent numbness and muscle paralysis (tetraplegia) that affects almost the whole body (from the neck to the toes) is usually caused by spinal cord injury due to fracture of the spine. When spin al injury occurs at the lower level, only legs can be affected (paraplegia). Numbness on one half of the body (left or right) is usually caused by stroke and is usually accompanied by muscle paralysis (hemiplegia) on the affected side. Numbness/Tingling in the Face Some causes: Stroke usually causes numbness on one half of the face In multiple sclerosis, numbness can come and go Hyperventilation due to anxiety or hard exercise can cause tingling around the mouth Food allergies can also cause tingling around the mouth In Herpes zoster (shingles), numbness and tingling is usually followed by tchy rash on one side of the face Transitional facial numbness can occur during seizures Numbness in the Arm, Hand or Fingers Disorders of the neck spine (herniated disc, rheumatoid arthritis) Compression of the nerves that supply the arm by the clavicle (thoracic outlet syndrome), common in overhead sport activities, for example in baseball Overuse or injury of the elbow (cubital tunnel syndrome) Overuse or injury of the wrist (carpal tunnel syndrome) Entrapment of the ulnar nerve in the wrist, common in cyclists (handlebar palsy) Metabolic disorders: calcium or potassium deficiency Panic attack Sleeping over the arm/hand Damage of the nerves in alcoholics and diabetics (peripheral neuropathy) Numbness in the Legs and Feet Nerve entrapment in the lower back (sciatica) Cold injury: frostnip, frostbite, chilblains Sitting with crossed legs Prolonged walking resulting in the compression of the tibial nerve and foot numbness Restless leg syndrome tingly and itchy lower legs from an unknown cause Hardening of arteries (atherosclerosis) in the legs in older people, especially in smokers Artery inflammation vasculitis We will write a custom essay sample on What is paresthesia? specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on What is paresthesia? specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on What is paresthesia? specifically for you FOR ONLY $16.38 $13.9/page Hire Writer How can be paresthesia diagnosed? It is a combination of symptoms, signs and investigations, such as CT scan or blood tests from which a doctor can make a diagnosis. For example, an individual who had a stroke usually has a history of the event with lost consciousness, numbness and paralysis on one side of the body and a lesion in the brain, which can be seen on MRI or CT scan. How is paresthesia treated? Treating of the underlying cause usually cures paresthesia.

Earthing systems Essays

Earthing systems Essays Earthing systems Essay Earthing systems Essay Introduction Purpose of earthing in an electric power system is to restrict, with regard to the general mass of Earth, the potency of current transporting music directors, which are portion of the equipment, and non- current transporting metal plants, associated with the equipment, setup and contraptions connected to the system. Type of Earthing Systems There are four chief type of earthing systems. These include: TN systems Point straight to land, the exposed conductive parts connected to this point the installing of the protection of music directors. Two types of TN system are approved for new installings in South Africa. These are defined harmonizing to the agreement of impersonal and protective music directors, as follows: TN-S system: in which throughout the system, a separate protective music director is used ; TN-S system: in which throughout the system, a separate protective music director is used ; TN-C-S system: in which the neutral and protective maps combined in a individual bid concatenation of system. TN-C-S system: in which the neutral and protective maps combined in a individual bid concatenation of system. TT system Which one point is straight earthed, the exposed-conductive-parts of the installing being connected to earth electrodes electrically independent of the Earth electrodes of the power system. The TT system is non permitted for new installings in South Africa, but still exists in many of the older countries. IT system Which has all unrecorded parts isolated from Earth, or one point connected to earth through an electric resistance, the exposed-conductive-parts of the electrical installing being earthed independently or jointly or to the grounding of the system. The IT system is non used for the public distribution of electricity, but is used in private installings, chiefly for grounds of continuity of service. Three phases IT systems with a distributed impersonal can in certain fortunes result in risky conditions. This latter type of IT system is to be deprecated. The jobs of electromotive force fluctuations between stage and impersonal that can ensue from a interruption in the impersonal, are common to all types of low electromotive force distribution systems. The increasing use of the TN-C-S system has nevertheless introduced a farther dimension to the effects of a loss of the impersonal music director. TN-C-S system Chiefly for economic grounds, across the Earth, the TN-C-S power system is going more and more widely used for the distribution of low electromotive force electrical power. The construct of uniting the impersonal and protective maps in a individual music director instantly resulted in the riddance of one of the five distributed music directors that are required for a three stage TN-S system ( three stages, one impersonal and one protective music director ) . In a TN-C-S system, the separate protective music director ( PE ) for each consumer, is created by merely tapping off a 2nd parallel music director from the PEN music director at a location that is close to or at the point of supply to single consumers. The parallel music director in the installing so becomes the impersonal music director. The chief disadvantage of the TN-C-S distribution system is this unprotected risky status that could originate in the event of a interruption in the PEN music director. This jeopardy continues to be independent of the presence of any protection devices that may be installed. In the event of a interruption in the PEN music director, all exposed conductive parts will stay unrecorded irrespective of the operating province of the chief shift or insulating device whether it is ON ( closed ) or OFF ( unfastened ) . Current pattern of adhering in HK Types of low electromotive force system as defined by the IEC and IEE are identified by the connexions to Earth of the beginning ( system Earth ) and the exposed conductive parts of the electrical installing ( equipment Earth ) . If these Earth terminuss are non boned together by a metallic music director the system is classified as TT, and the way for Earth mistake currents is so through the existent Earth or land, . If the terminuss are bonded together with a dependable and low electric resistance metallic connexion the return way will non be through the Earth and the system is classified as TN-S. The footings on which the CLP Power Hong Kong Ltd. and the Hong Kong Electric Co. , Ltd. will provide electricity are capable to the Electricity Supply Ordinance, and the ordinances and conditions laid down in the common set of Supply Rules published by both companies. By virture of his application for electricity supply or his obtaining electricity from the Company, a consumer is bound by and shall stay by the Supply Rules and other footings and conditions. Supply Rule 407.1 requires that for every electrical installing the consumer must supply his ain Earth electrode system by which the exposed conductive parts of his installing are connected to earth. That is, all exposed conductive parts of the installing shall be connected by protective music directors to the chief earthing terminus of the installing and that terminal shall be connected to earth electrode ( s ) via an earthing music director. This means that every installing is connected to be portion of a TT system. Rule 407.3.f. ( three ) further provinces that where the supply is taken direct from the Company s transformer or via belowground overseas telegram, the Company may let the consumer to supply a bonding music director between his chief earthing terminus and the Company s transformer Earth or metallic sheaths of the service overseas telegram. Therefore, the installing will be operated as portion of a TN-S system. However, this regulation besides states that in the measuring of the Earth mistake loop electric resistance or proving the operation of protective devices, the said bonding music director must be disconnected, i.e. the design and commissioning of the installing must presume a TT system. 3

Additionally, the battleships carried two 21 torpedo tubes.  For protection, the  Wyoming-class utilized the main armor belt eleven inches thick.   Assigned to New York Shipbuilding Corporation in Camden, NJ, construction started  on Arkansas  on January 25, 1910.  Work advanced over the next year and  the new battleship entered the water on January 14, 1911, with Nancy Louise Macon of Helena, Arkansas  serving as sponsor.  Construction concluded the following year and  Arkansas  shifted to the Philadelphia Navy Yard where it entered commission on September 17, 1912, with Captain Roy C. Smith  in command. USS Arkansas (BB-33) - Early Service Departing Philadelphia,  Arkansas  steamed north to New York to take part in a fleet review for President William H. Taft.  Embarking the president, it then carried him south to the Panama Canal construction site before conducting a brief shakedown cruise.  Retrieving Taft,  Arkansas  transported him to Key West in December before joining the Atlantic Fleet.  Taking part in routine maneuvers during the majority of 1913, the battleship steamed for Europe that fall.  Making goodwill calls around the Mediterranean, it arrived in Naples in October and aided in celebrating the birthday of King Victor Emmanuel III.  Returning home,  Arkansas  sailed for the Gulf of Mexico in early 1914 as tensions with Mexico increased. In late April, Arkansas  took part in the US occupation of Veracruz.  Contributing four companies of infantry to the landing force, the battleship supported the fighting from offshore.  During the battle for the city,  Arkansas detachment sustained two killed while two members won the Medal of Honor for their actions.  Remaining in the vicinity through the summer, the battleship returned to Hampton Roads in October.  Following repairs at New York, Arkansas  began three years of standard operations with the Atlantic Fleet.  These consisted of training and exercises in northern waters during the summer months and in the Caribbean in the winter.   USS Arkansas (BB-33) - World War I Serving with Battleship Division 7 in early 1917, Arkansas  was in Virginia when the US entered World War I that April.  Over the next fourteen months, the battleship operated along the East Coast training gun crews.  In July 1918,  Arkansas  transited the Atlantic and relieved USS  Delaware  (BB-28) which was serving with the 6th Battle Squadron in Admiral Sir David Beattys British Grand Fleet. Operating with the 6th Battle Squadron for the remainder of the war, the battleship sortied in late November along with the Grand Fleet to escort the German High Seas Fleet into internment at Scapa Flow.  Detached from the Grand  Fleet on December 1,  Arkansas  and other American naval forces steamed for Brest, France where they met the liner SS  George Washington  which was carrying President Woodrow Wilson to the peace conference at Versailles.  This done, the battleship sailed for New York where it arrived on December 26. USS Arkansas (BB-33) - Interwar Years In May  1919,  Arkansas served as a guide ship for a flight of US Navy Curtiss NC flying boats as they attempted a trans-Atlantic flight before receiving  orders to join the Pacific Fleet that summer.  Passing through the Panama Canal,  Arkansas  spent two years in the Pacific during which time it visited Hawaii and Chile.  Returning to the Atlantic in 1921, the battleship spent the next four years conducting routine exercises and midshipmen training cruises.  Entering the Philadelphia Navy Yard in 1925,  Arkansas  underwent a modernization program which saw the installation of oil-fired boilers, a tripod mast aft, additional deck armor, as well as the trunking of the ships funnels into a single, larger funnel.  Rejoining the fleet in November 1926, the battleship spent the next several years in peacetime operations with the Atlantic and Scouting Fleets.  These included a variety of training cruises and fleet problems. Continuing to serve, Arkansas  was at Hampton Roads in September 1939 when World War II began in Europe.  Assigned to the Neutrality Patrol reserve force along with USS  New York  (BB-34), USS  Texas  (BB-35), and USS  Ranger  (CV-4), the battleship continued training activities into 1940.  The following July,  Arkansas  escorted US forces to the north to occupy Iceland before being present at the Atlantic Charter conference a month later.  Resuming service with the Neutrality Patrol, it was at Casco Bay, ME on December 7 when the Japanese attacked Pearl Harbor. USS Arkansas (BB-33) - World War II Following training activities in the North Atlantic,  Arkansas  arrived at Norfolk in March 1942 for an overhaul.  This saw a reduction in the vessels secondary armament and an enhancement of its anti-aircraft defenses.  After a shakedown cruise in the Chesapeake,  Arkansas  escorted a convoy to Scotland in August.  It repeated this run again in October.  Beginning in November, the battleship began protecting convoys bound for North Africa as part of Operation Torch.  Continuing in this duty until May 1943,  Arkansas  then moved to a training role in the Chesapeake.  That fall, it received orders to aid in escorting convoys to Ireland. In April 1944, Arkansas  commenced shore bombardment training in Irish waters in preparation for the invasion of Normandy.  Sortieing on June 3, the battleship joined Texas  in Group II before arriving off Omaha Beach three days later.  Opening fire at 5:52 AM,  Arkansas first shots in combat struck German positions behind the beach.  Continuing to engage targets through the day, it remained offshore supporting Allied operations for the next week.  Operating along the Norman coast for the rest of the month, Arkansas  shifted to the Mediterranean in July to provide fire support for Operation Dragoon.  Striking targets along the French Riviera in mid-August, the battleship then sailed for Boston. Undergoing a refit,  Arkansas  prepared for service in the Pacific.  Sailing in November, the battleship reached Ulithi in early 1945.  Assigned to Task Force 54,  Arkansas  took part in the invasion of Iwo Jima beginning on February 16.  Departing in March, it sailed for Okinawa where it provided fire support for Allied troops following the landings on April 1.  Remaining offshore into May, the battleships guns bombarded Japanese positions.  Withdrawn to Guam and then the Philippines, Arkansas  remained there into August.  Sailing for Okinawa late in the month, it was at sea when the word was received that the war had ended. USS Arkansas (BB-33) - Later Career Assigned to Operation Magic Carpet,  Arkansas  aided in returning American servicemen from the Pacific.  Employed in this role through the end of the year, the battleship then remained at San Francisco through the early part of 1946.  In May, it departed for Bikini Atoll via Pearl Harbor.  Arriving at Bikini in June, Arkansas  was designated as a target ship for the Operation Crossroads atomic bomb testing.  Surviving Test ABLE on July 1, the battleship was sunk on July 25 following the underwater detonation of Test BAKER.  Officially decommissioned four days later,  Arkansas  was struck from the Naval Vessel Register on August 15.

Globalizations affect the labour of North America Essay

Globalizations affect the labour of North America - Essay Example Manzella says "offshoring created 90,000 new IT jobs in the United States. in 2003". American companies have become more profitable and globally competitive because of low cost labor from overseas. Two-thirds of the economic benefits, such as monetary savings generated from hiring employees overseas are reinvested. It is not all about cheap labor. While low skilled jobs are often sent overseas, professionals will be in great demand over the next decade. There will be a need for architects, accountants, commercial/industrial designers and paralegals by as much as 29%. Even low end jobs such as customer service representatives will increase by 24% by 2012. As North American companies pursue the global market in an effort to make a profit, they have to focus on product design, branding strategies, productivity and respond to customers' needs. (Francis-Smith, 2005). Globalization represents a commitment and desire to create a better future. It conveys optimism, and offers endless possibilities for growth, renewal, and revitalization for every all involved. It brings a sense of connectivity, interdependence, and integration in the global community. Extending benefits and responsibilities on a global scale, it provides commonalities without overlooking differences. Globalization gives a company the ability to conduct business across borders in an open market, maximizing organizational benefits without causing social damage by violating the human rights of other cultures (Ali, 2001). The United Parcel Service (UPS) has seen global profits. The company has taken advantage of globalization with its purchase of the British carrier Lynx Express for $96.5 million and has established domestic services in China. As a result, last year UPS's net profit of $986 million has shown strength in all phases of the company's expanding empire. It is not only UPS but numerous American companies are able to reap huge profits due to the enormous cost savings. Companies can save by reducing their capital investment requirements, lowering the cost of parts and components, thereby achieving unprecedented economies of scales, and benefit from government incentives (Stalk, 2004). Providing the most saving, labor costs, contributes to about 60% of the total cost advantage. For example, a worker in the United States normally cost $15 to $30 per hour while a worker in China earns less than a $1 per hour. What a savings! An English speaking Indian employee typically costs 50%-60% less than the United States employee. An accountant in the United States might cost a business $26 to $30 per hour while a qualified accountant would only cost $10-$12 per hour in India. Low capital investment cost account for a 25% cost advantage. Though not much, every cent saved increases a company's profits. For instance, the costs to build and provide equipment for a factory in China would be much less than in the U.S. Reported savings are as much as 60%-70% because to build a factory in the United States would cost $50 million while in a low cost country it would only cost $15-$20 million. Such savings gives a company the ability to recover its investment quicker, and increase its capability for growth. Product design is another source

Assignment - Essay Example The first one is receiving computer print outs and records. The next step is the collection of ship and money. This is achieved through two ways; one is by bidding auctioned ship. This is followed by buying and selling ship during the auctions. The other potion is placing orders for construction of new ships. After that, the company now uses the existing record to calculate the size of the fleet. The available ships are then allocated to the different fishing areas and placed on the game board. Finally, the decision sheet is submitted to the operator. In ensuring that a fishing company gets the best form each transaction, it has to make crucial decisions. This is the reason to whether it needs to keep its fleet at its current size or expand it. In cases of expanding the fleet, decision has to be made at to whether the new ship should be acquired through bidding in an auction or ordering new ships to be constructed. In this experiment, the focus as on selling the fish cash at $ 20 per fish. The main expenses incurred were form buying ship form auctions and ordering the construction of new ones. The company also operated ship fleet in different fishing area which required additional maintenance costs. The ship sent to the deep sea made considerable greater returns in terms of the size of the fish catch compared to the coastal bank. The company ensured that it made great profits by maintaining low initial bank balances. From the decision sheet provided, it can be observed that the number of ships that remained in the harbor were hig her than the number of ship sent into deep sea or the coastal harbor. This shows that the company was not able to utilize its resources fully in order to get the maximum assets. At one point, there was only one ship sent to the deep sea while the rest 18 were at the harbor. This ensured that it got a great fish catch by maximally utilizing the existing resources. The great catch was also as a result

Compare and contrast at least three of Fanthorpes poems Essay Example for Free

Compare and contrast at least three of Fanthorpes poems Essay Four of Fanthorpes poems, Dear Mr. Lee, Youll Be Hearing From Us Shortly, Half Past Two and Not My Best Side all have things in common yet on different subjects. In her poems, Fanthorpe challenges our views particularly on stereotypes and prejudices both traditional and modern. The serious point of Dear Mr. Lee is to get across that looking at writing, so intensely can ruin the original idea the writer had. Some pieces of writing should just be read and enjoyed. Fanthorpe as a teacher often has to take apart pieces of work and analyse them yet she seems in this poem to disagree with the over analysing of writing. Also similar in all four of these poems is the structure. All are written as prose, the most obvious prose like poem is Dear Mr. Lee. It seems to be written as a letter by a student who has read Mr. Lees book. Yet looking further into the poem the reader discovers that it is actually written as the thoughts of the student. The way the student talks about and criticises the teacher. Mr. Smart is my least favourite person and Mr. Smart has to explain why theyre jokes are good examples of thoughts. Dear Mr. Lees lines end randomly, which is odd for a poem, rhythm and pattern are not present and generally the poem has no traditional poetry techniques such as alliteration, onomatopoeia and rhyme. Also not all the lines begin with capital letters, which is very strange for a poem. I wanted to say Dear Laurie (sorry) your books the one that made up for the other, The poem seems to be unplanned and has no apparent structure, using random line lengths, and also it seems to be this way because of the line beginning without capitals, which makes it, look messy and unplanned. Dear Mr. Lee is trying to get across a point that criticises the studying of writing whereas Not My Best Side challenges the use of stereotypes both traditional and modern. St George is a critic reading the poem making his objections to it, complaining about the way the new characters differ from the traditional or stereotypes. Dont you want to carry out the roles that sociology and myth have designed for you? Not My Best Side is more tongue and cheek than Dear Mr. Lee in the way it makes fun of the stereotypes. In many stories involving dragons, the dragon is often fierce and often the bad guy. Fanthorpe has made fun of this and made the dragon totally the opposite: vain, proud, patronising and feels he is superior. He is a prima donna. The woman is not beautiful, helpless and grateful to the hero. She is self-centred, and a gold-digger. Then there is St. George who is supposed to be brave, handsome and modest. Fanthorpes St. George is a modern day man with a huge ego. Not My Best Side also appears to be written as prose. Also it lacks traditional poetry techniques, as does Dear Mr. Lee. The lines seem to end randomly, and yet again there is also the use of brackets as afterthoughts, which are found, for the same reason in Dear Mr. Lee. Unlike Not My Best Side, Half Past Two may be written from a personal experience. From her experiences Fanthorpe tries to get across that there are different kinds of time. Fanthorpe uses the child to represent the first kind of time: Events that the child remembers or has picked up. The child does not know adult time and so uses events in the day as time. For example: Gettinguptime, and Timeyouwereofftime. The second time portrayed is real time. This type of time is the day divided up by the clock in hours and minutes. The third of time is suspended time. This is the type of time the child is in when he daydreams and drifts off into his own world. As he doesnt understand the adult time he goes into his own suspended time to escape. In Not My Best Side, Fanthorpe introduces three voices that divide the poem and show the reader who is speaking. This also appears in Half Past Two. There is the narrator, the teacher and the child. These three voices appear randomly within the stanzas whereas the three voices in Not My Best Side are used to divide the poem into stanzas. Like Dear Mr. Lee and Not My Best Side, Half Past Two is also written as prose. The randomly ending lines and use of brackets, also used in both Dear Mr. Lee and Not My Best Side emphasise the writing as prose. The brackets in Half Past Two represent afterthoughts, similar to Dear Mr. Lee and Not My Best Side. All of Fanthorpes poems seem to involve thoughts of someone, concerned about all that occurs in their own head. Maybe this person is Fanthorpe herself. Therefore the poems would be written about self-experiences. For example, the views of the Dragon, Princess, Knight, the suspended time of the child and the thoughts of the interviewee could all be taken as Fanthorpes own thoughts. Fanthorpes poems are idiosyncratic, all have a lose structure, the line endings are odd and stanza lengths are also all different. Her poetry is written mainly as prose and is easy to tell why, the use of brackets mid line to represent after thoughts and different length structure makes the poems look like prose writing. This is typical of Fanthorpes writing and hence her poems being similar in all ways.

Cyperus papyrus: From the Nile to Modern Times :: Botany

Cyperus papyrus: From the Nile to Modern Times Cyperus papyrus, commonly called papyrus or paper plant, is a member of the sedge family (Cyperaceae). It is a monocot that is native to riverbanks and other wet soil areas in Egypt, Ethiopia, the Jordan River Valley, and other parts of the Mediterranean basin (1). Few members of the sedge family hold economic importance as crop plants, but throughout the world these plants hold great regional importance in weaving mats, baskets, screens, and even sandals (3). Though not normally grown for crops sedges do hold economic importance to agriculture. A substantial amount of sedges are noxious weeds, invading crop fields in all climates of the world. These include species that invade rice paddies, grazing pastures, as well as others (3.) Sedges do however have a considerable amount of ecological importance. They are of extreme importance to primary production as well as an integral part of the hydrologic cycle (3.) C. papyrus is an aquatic plant that has woody, bluntly triangular stems and grows up to about 15 feet in quietly flowing water up to three feet deep and the stem can grow up to six centimeters in width near the top (4). While the bottom portion of the stem can be up to six inches in width (7). The stem has scattered vascular bundles and no inner pith, like other typical monocots. The stem is composed of cellulose (54-68%) and lignin (24-32%), this helps to provide support for the stem and subsequently helps maintain the plant structure. There are also air ducts in the stem to help the plant stay buoyant; this is an important adaptation since C. papyrus grows in wet conditions (1). The roots, which are rhizomes, spread over the water, forming floating mat. These mats can sometimes break apart allowing the plant to colonize new areas in rivers and lakes. This can sometimes cause problems for shipping vessel (1). The leaves of the paper plant are long and sharp-keeled and have parallel veination (7). The leaves also have an epidermis with no 'long' and 'short' cell differentiation. The leaves usually have silica bodies and stomata are present (6.) The leaves are arranged in umbels, or tufts, on the end of tall, leafless stems (1). The economic contributions of C. papyrus may not be evident to moderns, but its importance to some ancient civilizations is tremendous. The ancient Egyptians were using papyrus to make paper more than five thousand years ago to make the first paper (1.

Comparative between Oedipus and Lord of the Flies

A person's goals and ambitions often times do in fact interfere with the people around them. If someone is so determined to fulfill their dreams they often times do whatever it takes to do so, some people may even turn into a whole new person. Two characters from two different pieces of literature who face this struggle are: Oedipus from the play ‘Oedipus' by Sophocles and Ralph from the novel ‘Lord of the Flies' by William Golding. Oedipus' goal of seeking the killer of Lauis and finding out the truth about his life and Ralphs goal of survival and getting off the island both conflict with he others around them.Oedipus was very determined to figure out the truth about who killed King Lau's and the truth about his life and who his real parents were. The people around him kept telling him that he was the one who murdered Lauis and the woman, Jocasta that he was married to was in fact his biological mother and his father, who he had killed was Lau's. Oedipus of course could not face the truth and accept the fact that everyone was right so he was determined to keep seeking the killer.Oedipus talks to the blind prophet, Teresias about the truth and he ells him the same thing that everyone else has been telling him all along, that his mother was his wife and the man he killed was Lauis and Lauis was his father. ‘You are the cursed polluter of this land' ‘ (pg. 38) and again Oedipus disagrees with him, Teresias then calls him blind because he could not face the truth. This causes interpersonal conflict because the both of the men then start insulting and fighting with each other. â€Å"When you prove me wrong then call me blind† (pg. 8) Oedipus and Teresias argue and Oedipus says to him when you can prove me wrong about ctually killing Lau's and that He and Jocasta were actually my parents then you can call me blind to the truth. Before Oedipus accepts the fact that everyone was right he asks questions about where and when Lauis was kill ed because he ensures that it is actually the truth before he tells everyone he knows. (Did you not say that Lau's was killed in a place where 3 roads met? † (pg. 46) . Oedipus makes himself look bad for not listening to what people say and Just listening to himself and telling himself that nothing was true when it turns out it did.Oedipus then cannot live with himself for illing his biological father and then having a relationship with his mother so he then makes a decision to claw his eyes out and become blind because he was blind to the truth all along anyways. Oedipus cannot live with what had happened in his life so he claws his eyes out because after all he was blind to the truth after all. Before he does so he states † To a land of exile; brother as it shall be shown and father at once, to the children he cherishes , son and husband to the woman who bore him.Father- killer and father-supplanter† (pg. 38) basically meaning that he knew he done wrong nd that e veryone was right, but he was a good man through it all. Overall, someone goals can on fact cause a person to have conflict and arguments with society around. Not only does Oedipus' goals interfere with society around him in the play ‘Oedipus' by Sophocles but also in the novel ‘Lord of the Flies' by William Golding. The character Ralph has a goal and desire of surviving to live on the island and also being rescued trom the island.This struggle ot the character, Ralph causes contlict wit n the other boys on the island because after being on the island, isolated from family and friends hey basically change into other people or as they call themselves†animals†. They try to put order and rules in on the island for everyone to follow so they can at least be a little civil. Everyone agrees to put Ralph in charge on the island but after a while of taking orders from him the boys separate, Ralph needed to rules to ensure survival but everyone eventually turned on hi m for it. â€Å"There was a ship out there, you said you'd keep the fire going and you let it out! † (pg. 4) This quote is said by Ralph to the boys. Jack, another one of the boys on the island had a team of boys with him and heir goal was to keep the fire going on top of the mountain Just in case there had to be a ship out in the ocean, they were hoping there would be one out there so that the smoke from fire would inform the men/women from the ship that there were people on that island, but of course Jack did not complete this task, instead he and the boys went hunting, that is all they cared about it seemed. Ralph gave each and every boy a job on the island and to be fair, they all had to finish them, but that is not the way it went down.Ralph noticed no one was doing their given task so he got mad. Been working for days now and look! And they keep running off. You remember the meeting? How everyone was going to work hard until the shelters were finished† (pg. 51). O ne of the boys, Simon had some medical problems with having seizures, one night they got bad and he ran out of the woods uncontrollably, he could not talk right, the other boys ran after him like a pack of wild animals, they had â€Å"mistaken† him for the beast that they thought had been on the island, the boys unknowingly killed him brutally, stabbing him continuously.Afterwards Piggy and Ralph realized that it was ot the beast that they had killed, it was actually Simon, they felt nothing but guilt, they felt that they could have been more cautious. Piggy tried to get rid of the guilt by saying they were under pressure because they were scared but they both knew that was not the case. â€Å"Don't you understand,Piggy? The things we did. † (pg. 173) Ralph talks about the things they did, referring to the death of the boy, Simon, you can tell that they felt guilt. l wasn't scared, I was – I don't know what I was† (pg. 173). Here Ralph states that he knew they were not scared of the thing that popped out of the oods, that turned out to be Simon, he knew that that was not the reason why everything went wrong,deep down they all knew that it was because of how much they changed and turned into savages from being isolated on the island with nothing. In comparison of the two works, they both have similarities in terms of society being affect by a specific character. Comparative between Oedipus and Lord of the Flies A person’s goals and ambitions often times do in fact interfere with the people around them. If someone is so determined to fulfill their dreams they often times do whatever it takes to do so, some people may even turn into a whole new person. Two characters from two different pieces of literature who face this struggle are: Oedipus from the play ‘Oedipus’ by Sophocles and Ralph from the novel ‘Lord of the Flies’ by William Golding.Oedipus’ goal of seeking the killer of Lauis and finding out the truth about his life and Ralphs goal of survival and getting off the island both conflict with the others around them. Oedipus was very determined to figure out the truth about who killed King Lauis and the truth about his life and who his real parents were. The people around him kept telling him that he was the one who murdered Lauis and the woman, Jocasta that he was married to was in fact his biological mother and his father, who he had killed was La uis. Oedipus of course could not face the truth and accept the fact that everyone was right so he was determined to keep seeking the killer.Oedipus talks to the blind prophet, Teresias about the truth and he tells him the same thing that everyone else has been telling him all along, that his mother was his wife and the man he killed was Lauis and Lauis was his father. â€Å"You are the cursed polluter of this landâ€Å" (pg.38) and again Oedipus disagrees with him, Teresias then calls him blind because he could not face the truth. This causes interpersonal conflict because the both of the men then start insulting and fighting with each other. â€Å"When you prove me wrong then call me blind† (pg.38) Oedipus and Teresias argue and Oedipus says to him when you can prove me wrong about actually killing Lauis and that He and Jocasta were actually my parents then you can call me blind to the truth.Before Oedipus accepts the fact that everyone was right he asks questions about wh ere and when Lauis was killed because he ensures that it is actually the truth before he tells everyone he knows. (Did you not say that Lauis was killed in a place where 3 roads met?† (pg.46) . Oedipus makes himself look bad for not listening to what people say and just listening to himself and telling himself that nothing was true when it turns out it did. Oedipus then cannot live with himself for killing his biological father and then having a relationship with his mother so he then makes a decision to claw his eyes out and become blind because he was blind to the truth all along anyways.Oedipus cannot live with what had happened in his life so he claws his eyes  out because after all he was blind to the truth after all. Before he does so he states â€Å" To a land of exile; brother as it shall be shown and father at once, to the children he cherishes , son and husband to the woman who bore him. Father-killer and father-supplanter† (pg.38) basically meaning that he knew he done wrong and that everyone was right, but he was a good man through it all. Overall, someone goals can on fact cause a person to have conflict and arguments with society around. Not only does Oedipus’ goals interfere with society around him in the play ‘Oedipus’ by Sophocles but also in the novel ‘Lord of the Flies’ by William Golding.The character Ralph has a goal and desire of surviving to live on the island and also being rescued from the island. This struggle of the character, Ralph causes conflict with the other boys on the island because after being on the island, isolated from family and friends they basically change into other people or as they call themselvesâ€Å"animals†. They try to put order and rules in on the island for everyone to follow so they can at least be a little civil.Everyone agrees to put Ralph in charge on the island but after a while of taking orders from him the boys separate, Ralph needed to rules to ens ure survival but everyone eventually turned on him for it. â€Å"There was a ship out there, you said you’d keep the fire going and you let it out!† (pg.74) This quote is said by Ralph to the boys. Jack, another one of the boys on the island had a team of boys with him and their goal was to keep the fire going on top of the mountain just in case there had to be a ship out in the ocean, they were hoping there would be one out there so that the smoke from fire would inform the men/women from the ship that there were people on that island, but of course Jack did not complete this task, instead he and the boys went hunting, that is all they cared about it seemed.Ralph gave each and every boy a job on the island and to be fair, they all had to finish them, but that is not the way it went down. Ralph noticed no one was doing their given task so he got mad. â€Å"Been working for days now and look! And they keep running off. You remember the meeting? How everyone was going t o work hard until the shelters were finished† (pg.51). One of the boys, Simon had some medical problems with having seizures, one night they got bad and he ran out of the woods uncontrollably, he could not talk right, the other boys ran after him like a pack of wild animals, they had â€Å"mistaken† him for the beast that they thought had been on the island,  the boys unknowingly killed him brutally, stabbing him continuously.Afterwards Piggy and Ralph realized that it was not the beast that they had killed, it was actually Simon, they felt nothing but guilt, they felt that they could have been more cautious. Piggy tried to get rid of the guilt by saying they were under pressure because they were scared but they both knew that was not the case. â€Å"Don’t you understand,Piggy? The things we did.† (pg.173) Ralph talks about the things they did, referring to the death of the boy, Simon, you can tell that they felt guilt. â€Å"I wasn’t scared, I w as – I don’t know what I was† (pg.173). Here Ralph states that he knew they were not scared of the thing that popped out of the woods, that turned out to be Simon, he knew that that was not the reason why everything went wrong, deep down they all knew that it was because of how much they changed and turned into savages from being isolated on the island with nothing.In comparison of the two works, they both have similarities in terms of society being affect by a specific character. Both of the books are affected by setting as well, the characters, Ralph and Oedipus have goals that have to do with setting, which then causes conflict with society. In the play ‘Oedipus’ by Sophocles, Oedipus’ goal of setting is trying to figure out the truth of his life; who killed Lauis and who his real parents were. This causes conflict with the citizens around him because he constantly shuts people down when they try to help him and tell him the truth. â€Å"Y ou are the cursed polluter of this land† (pg.38) Teresias states that the one who ruined the land was, Oedipus, him saying that then caused argument, because Oedipus listened to no one he just believed he was right.Conflict with others helped him piece together the truth of his life, he then states â€Å" To a land of exile; brother as it shall be shown and father at once, to the children he cherishes , son and husband to the woman who bore him. Father-killer and father-supplanter† (pg.38) it causes conflict with others because when Jocasta realized what had happened, she then killed herself. This play is similar to the novel â€Å"Lord of the Flies† by William Golding because the setting of the Lord of the Flies influence the goals of the character Ralph which then causes conflict with others, the setting in which the boys are in causes Ralph to have a goal of survival and to get off the island, he puts rules in order which not everyone agrees to so that then ca uses conflict and uproar on the island. â€Å"we’re on an island, we’ve been on  the mountain top and seen water all around† (pg.31)This shows when the boys have just arrived there and when they first realized where they actually were and that they were there alone. â€Å"we saw no houses, no smoke, no footprints, no boats, no people, we’re on an uninhabited island† (pg.31) this quote states the struggles they have ahead of them with being so young and having to be able to survive alone, Ralph knew they needed to put some order in so he does, he becomes captain but not everyone agrees with the jobs he puts in place, which is why it caused conflict. As you can see both of these books are similar in the sense of setting, and how it eventually aids in making conflict.Overall these two pieces of literature do show how a person’s desires and goals, conflict and interfere with the ones around them, whether they mean to or not, sometimes they may not even mean too, but if someone is so determined to complete their goal it can have a big impact on people’s lives around you, it can affect the way they live for the rest of their lives.

Explore the Ways in Which Bullies and Victims Are Present in Lord of the Flies and Dna Essay

English coursework, James Luxton Explore the ways in which bullies and victims are presented in Lord of the Flies and DNA. Bullies and Victims play vital roles in both the novel and the play. The authors, Golding and Kelly, both put their characters through similar trials. In Lord of the Flies, Golding’s characters turn from normal school boys, to savages who are prepared to kill one another to gain power. Golding suggests that under certain circumstances, people will naturally begin to become more violent and savage. In DNA the characters are thrust into a world of secrecy where they have to cover things up to save themselves, Kelly himself wrote this; ‘I don’t think I write characters who are bad, I think I write characters who are trying to do the right thing, but are failing’. Kelly gives no description to the lives of his characters before the death of Adam, suggesting that they may have lead innocent lives, but they have been thrust into a world of violence that spirals out of contro l. In Lord of the Flies, Golding impresses upon the reader how children’s judgements of their peers are based around their physical appearance which will directly impact whether they are seen as possible leaders or victims. In contrast, Kelly gives us no description of his characters’ appearance and offers no real clear reason why Adam is the victim; in this way the violence is less readily understood, and ultimately more frightening. Golding clearly demonstrates to the reader how physical appearance effects a character’s treatment in the opening chapter of Lord of the Flies. Even though they have just survived a plane crash and are apparently the only survivors on the island, Ralph constantly snubs Piggy; based on the fact that Piggy is fat, has asthma, and also wears glasses. Ralph shuns him, despite Piggy being incredibly intelligent, and it is Piggy who suggests most of the things for the boys to do, such as using the conch to call an assembly. Ralph doesn’t realise the true value of Piggy until after his death. ‘There was no Piggy to talk sense’ shows Ralph’s despair. When he really needed help, Piggy was always there to offer advice, whereas now, after his death, Ralph doesn’t know what to do. Through this Golding is inferring that people judge others solely on their appearance, and people who appear weak will always be targeted by society, no matter how intelligent they are. In complete contrast, Kelly gives the reader no description of any character in DNA, and in fact no description of the  scenery. Kelly gives no clear indication of why Adam is the victim, which suggests that any other one of the characters in the play may have been the victim, and on a much wider scale, it suggests that anybody in society may be susceptible to becoming a victim; this makes the violence that the group inflict on Adam much more frightening, because we are more likely to think that this could even happen to us. Kelly shows us through his depiction of Adam just how desperate some people are to become part of a group. Adam must continually show loyalty to them all in order to feel safe. They become so desperate to be popular and accepted by people, they are willing to do anything for the group or the people in power; to the point where they are literally willing to risk their lives. Kelly also depicts just how far a group of ‘bullies’ will go to test loyalty. The group made Adam ‘run across the motorway’ and ‘nick some Vodka’; these criminal and life-threateni ng activities were readily undertaken by Adam even though Jan acknowledges that ‘you could tell he was scared’. Alarmingly, the group were simply testing ‘how far he’ll go’. Kelly demonstrates how groups can manipulate people and exploit their fear and desperation to belong rather than be alone. . Kelly shows this through Mark when he says ‘we can make him do, we can make him do-‘ Mark’s repletion and unfinished sentence suggests that he was possibly so uncomfortable with what was done that he struggles to fully acknowledge it. Although he claims that they were ‘having a laugh, really, he was laughing’, his words give him away. He sounds as if he is trying to convince himself and the separation of the word’ really’ makes him sound desperate. Golding also suggests to the reader just how desperate people are to become part of a group, and how in some situations, becoming part of a group may literally be a life and death decision. Ralph, Jack and Simon set out to explore the island, and Piggy suggests to Ralph that he should go too, because he ‘was with him when he found the conch’ and he ‘was with him before anyone else was’. Ralph seemingly tries to put Piggy down gently by saying ‘you’re no good on a job like this’ implying, again, because Piggy is fat and has asthma, he won’t be able to keep up and he will be a burden to the other boys. In contrast Jack is blunter with Piggy. He simply says ‘we don’t want you, thre e’s enough’. In this, Jack shows obvious contempt for Piggy. When he firsts speaks to Piggy all he has to offer is ‘you’re talking too much, shut up fatty’. Jack’s obvious loathing of Piggy is evident  throughout the novel. Through Jack’s first contact with Piggy it strengthens the idea that children judge people solely on looks, and as well as this it is obvious that the constant name calling and bullying of Piggy will render him the victim of the boys throughout the novel. Both Golding and Kelly alarm their readers with evidence of real violence from the bullies to their chosen victims. Violence with stones occurs both in Lord of the Flies and DNA, but they have different consequences. In Lord of the Flies the violent acts begins with Maurice and Roger kicking through the littleuns’ sandcastles. Before the arrival of Roger and Maurice, the littleuns’ seem content with being detached from the other boys. Three boys played on the beach, ‘if not happily, at least with absorbed attention’. Golding suggests that the littleuns’ had nothing else to do besides eat, sleep and play, so the novelty of the being able to do anything has worn off, but ‘with absorbed at tention’ indicates they still posses the innocence of childhood, so they carry on playing regardless. In contrast, once Roger and Maurice had kicked over their sandcastles, the littleuns’ seemed disinterested, ‘so they made no protest’. Maurice kicks sand into Percival’s eyes, and his reaction to doing this is interesting. Maurice feels guilt through the description of his actions. Instead of staying with Roger, ‘he muttered something about a swim and broke into a trot’. The use of the word ‘muttered’ is significant because it infers that Maurice is trying to create excuses for himself, which shows unease at his actions. In his decision to run to the boys who are swimming, Golding shows that Maurice wants to detach himself from Roger. It is also noteworthy that he runs away from Roger towards the other boys, inferring that Maurice wishes to distance himself from Roger and the possibility of further actions. Johnny, one of the other littleuns’ playing around the sandcastles, then begins to copy the actions of Maurice; he begins to throw sand into Percival’s eyes. This is reminiscent of the Bandura experiment of 1977, in which he placed an adult in a room with a young child. The adult was given a Bobo doll, which he was told to abuse repeatedly in the presence of the child. The adult then left and the Bobo doll was given to the child. Over time the child would begin the re-enact the actions of the adult, the child would begin to abuse the Bobo doll; this suggests that children are influenced by a person in authority, and that they will copy their actions. Johnny repeats the actions undertaken by  Maurice, and this suggests that natural order on the island is beginning to weaken, and that aggression and violence is taking over, now even the youngest children on the island are beginning to experiment with violence. Golding then demonstrates this experimentation of violence t hrough Roger’s ‘stalking’ of Henry, the third littleun’ that was playing around the sandcastles. Henry ‘wandered off along the beach’, he detaches himself from the rest of group, in this sense his exposes himself and leaves himself vulnerable, but in doing this it shows the reader that he still posses childhood innocence and naivety. Roger follows Henry, hiding in the shadows along the beach. Golding creates and air of menace around roger through his ‘stalking’ of Henry. As well as this he suggests to the reader that Roger has no fear, when coconuts ‘as big as rugby balls’ , ‘fell about him with a series of hard thumps’. This lack of care for his own safety is frightening because he doesn’t think in the expected way of a young child. The violent acts Roger then commits are frightening because they are simply not expected of a young child. Roger ‘picked up a stone, aimed, and threw it at Henry-threw to miss’. But then he doesn’t stop there. He continues with these violent acts, he gathers ‘a handful of stones and began to throw them’. Roger’s violent acts tell the reader that now almost all of the expected childhood innocence has gone, and that the victims are starting to become apparent. The young, weaker children will be picked on because they are ‘batty’ and even some of the older boys such as Piggy and Simon will be targeted by looks and personalities. The violen ce on the island becomes more real and much more terrifying because the violence that would normally be expected of adults is being carried out by young children. In DNA the use of stones is much more violent, to the point where it leads to a death. The group continue to humiliate Adam, and they continue to test his loyalty to the group. They ‘went up the grille.’ They force Adam to climb a fence and go walk over a grille covering a hole. This alone is potentially life threatening to Adam. The group see that he is scared, and the group mind set is simply to taunt him and to humiliate him. They then being to start ‘pegging’ stones at him. The use of the word ‘pegging’ is important because it suggest to the reader that the group are actually trying to hit Adam ‘just for a laugh’. Even when the stones hit Adam directly on the head, they carry on laughing at him, because ‘the shock on his face is so†¦funny.’ When Adam slips and falls into the hole underneath the grille, that’s when it becomes evident that Mark, the character describing the ‘stoning’, realises the consequences of their actions. He repeats ‘so he’s†¦Ã¢â‚¬â„¢ a number of times. It is clear that he is unable to come to terms with the fact that he has participated in a murder, and it takes John Tate, the assumed leader of the group, who earlier banned the word ‘dead’, to finish Mark’s sentence. ‘Dead. He’s dead’. In Lord of the Flies the same violent symbol is used by Jack and Roger. The sharpening of a stick at both ends. The symbol first comes into use after the ‘hunters’ kill a pig. He orders Roger to ‘ram on end in the earth’. After doing this, Jack, who has decapitated that dead pig, then ‘jammed the soft throat down on the pointed end if the stick’ this is the first real sign that the boys have transcende d into savages. Jack then says ‘it’s a gift’ for the beast. Through this it suggests that the boys want to pacify the ‘beast’, and in killing the pig and offering its head it’s almost as if they are worshiping it, as if it has become like a god in which they must pay tribute to. When Roger sharpens the stick at two ends, the meaning of this is much more menacing. The boys have now turned into savages, after the deaths of Piggy and Simon, Jack is adamant that Ralph must be captured, and it is evident that Ralph will eventually be killed after torture if he is caught. Ralph is hiding from the rest of the boys, but he meets Sam’n’Eric one night so he can find out what will happen to him. At first the twins are reluctant to tell him what Jack has planned, but then came ‘the incomprehensible reply’, ‘Roger sharpened a stick a both ends’. Ralph is unable to see the true meaning in this, but it is obvious to the reader that Jack wants the same fate for Ralph, as the pigs head earlier in the novel. Roger throughout the novel is presented as the ruthless bully, from when he was throwing stones at Henry, he was the one who released the rock that killed Piggy, and now it is clear that he has been ordered to literally bring back Ralph’s head. The most frightening moment in DNA comes as a threat from Cathy once she has found Adam. She finds him ‘living in a hedge’ and after she tries to coax him out, Cathy openly admits that she ‘used violence’, she ‘threatened to gouge one of his eyes out’ this is a reference to Shakespeare’s King Lear when Goneril and Reagan rip out Gloucester’s eyes. Cathy throughout the play is shown to be the most frightening character. She is solely motivated by becoming famous through  interviews after Adams memorial, she says ‘it’s quite exciting’, suggesting that she enjoys the violence of the situation and she is enjoying the spot light. She has no consideration for Adam’s well being, she is self absorbed. In Richard’s speech at the end of the play, he tells Phil that Cathy is ‘insane’, and that ‘She cut a first year’s finger off’. Cathy and Roger are similar in that they both seem to enjoy inflicting pain on other people; they both come across as sadists. Their actions are terrifying to the audience because their extreme acts of violence would normally have been carried out by adults, but because they are both children, and Roger being so young, the violence is much more frightening. In Richards’s final speech in DNA, he is sitting in a field talking to Phil. This reminds us Leah, who throughout the play has long monologs when she is talking at Phil, in hope of a response. Phil blanks Richard, which tells the audience that he shuts out everybody, and that his silence wasn’t personal to Leah. The scene also suggests that nothing has changed, and it makes the audience reflect on the characters. Golding’s portrayal of the boys stays clearly on the same route. It’s suggested that Jack is evil and that evil continues through the novel, whereas Kelly makes us remember in the final scene of Leah, through Richard, and that Kelly wants to make us reflect on our views of each character, because they could be interchangeable, and they can represent anyone in society.

Computer Animators essays

Computer Animators essays Animation as an art form has been around for almost one hundred years. From the earliest days of hand drawn cels, individual pictures strung together, to the complex rendering of 3-D virtual worlds, animation packs peoples' lives. Do you wonder how the computer-animated movies are made or want to become a computer animator? Computer Animation is a fast growing field. There are many different areas to of animation, computer animation is what this paper is about, history of animation and how it came to be and how to get there and what computer animators do for their job is what is in this paper. Animation was first developed in 1906 by Stuart Blackton, a young English-born adventurer. His first short film, Humorous Phases of Funny Faces, was a sensation with audiences. Blacktons illusion was created by a very simple method, comical faces were drawn on a blackboard, then erased. The camera was stopped after each face was photographed. The 'stop-motion' provided a startling effect as the facial expressions changed before the audience's eyes. A major breakthrough for animation came in 1915, when J. R. Bray was granted patents for his use of glassine paper. Bray created a two-dimensional look with his animation by drawing on a clear plastic sheet and then placing it over a pre-drawn background. Max Fleischer's rotoscope consisted of a drawing board, fitted with a piece of frosted glass, and a motion picture projector mounted underneath which magnified a single frame of motion picture film onto the glass. When the figure on one frame had been traced onto translucent paper, a crank advanced the film to the next frame. People who choose a career path as a professional animator work in a challenging, fast-paced, and rewarding field. The resurgence in popularity of animation has re-opened countless opportunities for highly creative individuals, with computer skills. The latest need for computer animators is create...

Bipolar Disorder 2

Bipolar Disorder 2 Essay Bipolar affective disorder has been a mystery since the 16th century. History has shown that this disorder can appear in almost anyone. Even the great painter Vincent Van Gogh is believed to have had bipolar disorder. It is clear that in our society many people live with bipolar disorder; however, despite the amount of people suffering from it, we are still waiting for explanations for the causes and cure. The one fact of which we are aware is that bipolar disorder severely undermines its victims ability to obtain and maintain social and occupational success. Because bipolar disorder has such debilitating symptoms, it is important that we keep looking for explanations of its causes and for more ways to treat this disorder. Bipolar has a large variety of symptoms, divided in two categories. One is the manic episodes, the other is depressive. The depressive episodes are characterized by intense feelings of sadness and despair that can turn into feelings of hopelessness and helplessness. Some of the symptoms of a depressive episode include disturbances in sleep and appetite, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and reoccurring thoughts of death and suicide. The manic episodes are characterized by elevated or irritable mood, increased energy, decreased need for sleep, poor judgment and insight, and often reckless or irresponsible behavior. These episodes may alternate with profound depressions characterized by a deep sadness, almost inability to move, hopelessness, and disturbances in appetite, sleep, problems with concentrations and driving. Bipolar affective disorder affects approximately one percent of the population (approximately three million people) in the United States. It occurs in both males and females.Bipolar disorder is diagnosed if an episode of mania occurs whether depression has been diagnosed or not. Most commonly, individuals with manic episodes do experience a period of depression. Symptoms include elated, excited, or irritable mood, hyperactivity, pressure of speech, flight of ideas, inflated self-esteem, decreased need for sleep, distractibility, and excessive involvement in reckless activities. As the National Depressive and Manic Depressive Association (MDMDA) has found out in their research, bipolar disorder can create marital and family disruptions, occupational setbacks, and financial disasters. Many times, bipolar patients report that the depressions are longer and increase in frequency as the person ages. Many timess bipolar states and psychotic states are misdiagnosed as schizophrenia. The onset of Bipolar disorder usually occurs between the ages of 20 and 30 years of age, with a second peak in the mid-forties for women. A typical bipolar patient may experience eight to ten episodes in their lifetime. However, those who have rapid cycling may experience more episodes of mania and depression that follow each other without a period of remission. The three stages of mania begin with hypomania, in which patients report that they are energetic, extroverted and assertive. Hypomania progresses into mania and the transition is marked by extreme loss of judgment. Often, euphoric grandiose characteristics are displayed, and paranoid or irritable characteristics begin. The third stage of mania is evident when the patient experiences paranoid delusions. Speech is generally rapid and hyperactive behavior sometimes turns into violence. Sometimes both manic and depressive symptoms occur at the same time. This is called a mixed episode. Those affected are at special risk because there is a combination of hopelessness, agitation, and anxiety that make them feel like they could jump out of their skin. Up to 50% of all patients with mania have a mixture of depressed moods. Patients report feeling dysphoric, depressed, and unhappy; yet, they have the energy associated with mania. Rapid cycling mania is another form of bipolar disorder. Mania may be present with four or more episodes within a 12 month period. Lithium has been the primary treatment of bipolar disorder since its introduction in the 1960s. Its main function is to stabilize the cycling characteristic of bipolar disorder. In four controlled studies by F. K. Goodwin and K. R. Jamison, the overall response rate for bipolar subjects treated with Lithium was 78% (1990). Lithium is also the primary drug used for long- term maintenance of bipolar disorder. In a .

Health care Education Essay Example | Topics and Well Written Essays - 750 words

Health care Education - Essay Example It is vital to place persons as well as their families in suitable context. Comprehending the wider cultural context in which families are entangled can help as important related data for directing assessments and scheduling intervention approaches. Ethnic facets such as ethics, principles, customs, and pattern of family may be utilized as clues, as a portion of the entire information gathered concerning clients who are taught. Gay (2000) has described culturally responsive teaching as consuming the cultural knowledge, previous involvements, and individual needs of diverse students in order to make learning more suitable and operative for them.  He has also defined culturally responsive teaching as comprising of these characteristics: Ethnicity is also a vital variable in how people with disabilities and/or illness are looked upon and treated by the members of their family as well as how their household, in turn, is observed by their community overall. Cultural influences facilitate ways in which symptoms are recognized and understood, suitable manners of expression of pain as well as discomfort, whether a specific chronic condition is extremely denounced or established, and whether the dependence that escorts chronic illness is disvalued or deliberated upon as a portion of the normal sequence of life. Finally, ethnicity may have a major impact on the ways in which families cooperate with health specialists and deliberations that practitioners must give for their care to be most operational. For instance, in the Latina culture, as a symbol of respect, elder persons should be spoken to by using their last name. Signalling should not be used because apparently benevolent body or hand movements may have contrary connotations in the rest of the cultures. Outright interrogative of expert such as a physician is offensive in some
