A modern audience Essay
But her marriage to will is all a practical arrangement as she is good at her job and Will is a skilled craftsman. As this partnership moves on the pair become more successful, they manage to pay back Mrs Hepworth the loan she gave then to get started and we see a more romantic side to Maggie as she saves a flower from her wedding day bouquet.à ââ¬Å"I thought Iââ¬â¢d press it in my bibleà For keep sakeâ⬠A factor about Maggie that would appeal to a modern audience is that she is very intelligent. She controls the accounts and organises everything at Hobsonââ¬â¢s. She taught Will to read and write, because Will was born into the lower class she was not properly educate and so he was illiterate but Maggie changed that by educating him herself:à ââ¬Å"Iââ¬â¢ll just set you a short copy, for tonight.â⬠à Maggie is honest and fair, when Albert and Freddy are trying to get more money than they agreed out of Mr Hobson, she knows he cannot afford what they are asking and so she gets them down to a more realistic price:à ââ¬ËI know perfectly well what father can afford to pay, and it is not a thousand pounds nor anything like a thousand pounds.ââ¬â¢ Maggie is also humble because she is not afraid to ask for help when she needs it. She asks Mrs Hepworth for money as her and will havenââ¬â¢t got any from their previous jobs because Hobson didnââ¬â¢t pay Maggie and Will came from a lower class and had little pay, all to get married and start up a good businessà ââ¬Å"Weââ¬â¢ve paid back Mrs Hepworth what she lent us for our start and made a bit oââ¬â¢ brass on top oââ¬â¢ that.â⬠à At the beginning of the play Will lacked self-confidence and he was poor. He was also a victim of Hobsonââ¬â¢s exploitation:à ââ¬Å"What does she want to praise workmen to his face for?â⬠But Will is a talented craftsman and a skilled worker which is why Mrs Hepworth complimented him and asked that he makes her shoes in the future:à ââ¬Å"These are the best-made pair of boots Iââ¬â¢ve ever had. Now, youââ¬â¢ll make my boots in future.â⬠à This is a great compliment for a working class man because they were not often praised for their work and didnââ¬â¢t often do so well. This is a point about Will that would appeal to a modern audience.à Will, like many other working class in the 1880ââ¬â¢s could not read at the start of the play but due to Maggieââ¬â¢s help he learns how to read and write. By starting up his own business shows he is a good business man and he pays off Mrs Hepworth the money back she lent the couple to get the business started. ââ¬Å"Weââ¬â¢ve paid off Mrs Hepworth what she lent us for our start.â⬠à Will is from a working class background; he is one of Hobsons boot hands and suffers social prejudice from Maggies sisters Alice and Vicky but now is near equal class to them but they still see him form a lower class and treat him with a lack of respectà ââ¬Å"Will Mossop do you know who you are talking to?â⬠à As the play progresses Wills confidence increase as he now dares to stand up to Hobson, Alice, Vicky and Maggieà ââ¬Å"Iââ¬â¢ll take you into partnership and give you a half shareâ⬠. The Audience may find Wills character comical due to his sayings ââ¬Å"Well by gumâ⬠à And make the viewers laugh. When Maggie tells Will she wants to marry him he is a bit worried at tries to back down from the proposal because he did not love her, but they get their partnership up and running and as the story continues he realises that he can learn to love and give Maggie the respect she needs to create a successful business. From the start to the end of the play Will Mossop changes a lot. He went from working in Hobsonââ¬â¢s cellar to owning his own successful business and being married to Maggie. His main change was that he went from poverty to being a member of the working/middle class. By doing this he has made his way up the social ladder, which was very hard to do in the 19th century. Wills struggle could be compared to a dream going from rags to riches. In my opinion this would be the most important factor about Will that would appeal to a modern audience.à Maggieââ¬â¢s determination to make a success of hers and Willieââ¬â¢s marriage and the business that they start would make her popular with a modern audience because she did not really love Will when they were married, but she had to do something to get away from Mr Hobson, her authoritarian father and she also managed to get her sisters married.

Philiosophies in Early Childhood Teaching Essay
Formal Writing Assignment: Introduction to Early Childhood Education Instructor: Ecole Morris- University of Montana-Western Goal: to develop a personal teaching philosophy of early childhood education based on research and analysis. Purpose: If someone asked you to explain your philosophy of teaching young children, what would you say? How would you begin to formulate a statement that captures the essence of your belief about teaching and learning? Teacher candidates are increasingly being asked to articulate their philosophy of teaching. This request is often in conjunction with the submission of a teaching portfolio for seeking teaching positions or dossier for promotion and tenure. A teaching philosophy is a statement of reflection about what you will do as a teacher. Your beliefs influence your action. It has been recognized by many teachers that the process of identifying a personal teaching philosophy and continuously examining, testifying, and verifying this philosophy can lead to change of teaching behaviors and ultimately enhance professional and personal growth. Assignment: For this assignment articulate your teaching philosophy in two phases. (100 points) 1. Introduction: at the beginning of the semester, you are required to write a 4-5 page paper. In it, consider the following points: * Why do you want to become an early childhood education teacher? * What type of teaching position do you hope to obtain, and why? * What are your strongest characteristics or talents as a potential early childhood educator? * What are the factors that influence your decision to pursue this career? 2. Areas to emphasize: Use the following questions to help you think about your beliefs regarding teaching young children. It is not necessary to respond to each of these questions in your written philosophy. You may also decide to comment on additional issues as well. Take some time to think about each one in some depth. * How do you view young children? What is the childââ¬â¢s role in his/her education? What do you belief about how young children learn? * What role does family play in your teaching? How will you include them in your classroom? * What are your views on inclusion, how will you include all children in your classroom? * How do you view the role of the teacher? How will your views influence your teaching? * What kind of environment do you hope to create in your future classroom? How does this relate to your basic beliefs about young children and learning? * What do you hope young children will become? What do you want them to achieve, accomplish, learn, feel, etc.? * What kind of feedback will you offer your students as they work? What kind of assessment will you use to be sure that students have met objectives? * Looking back at the history of early childhood education, who or what approaches have the greatest impression on you, and why? General Paper Format Suggestions: * Use present tense, in most cases. Write the paper in first-person (which is the most common and easiest for your audience to read). * Write in language and concepts that can be broadly appreciated. A general rule is that the statement should be written with the audience in mind. It may help to consider a school administrator (e.g. , school principal) as your audience. * Write a paper that will let your audience know where you stand in regard to important educational theories and practices. By including specific examples of teaching theories and approaches, you are able to let your reader take a mental ââ¬Å"peekâ⬠of your classroom. * Make the paper memorable and unique. Think of this teaching philosophy as part of a job application where your readers are seeing many of these statements. What is going to set you apart from others? What about you are they going to remember? Create a vivid portrait of yourself as someone who is intentional about teaching and committed to his/her career. * A working draft will be developed and reviewed by a peer during the class. This working draft will be submitted with the final draft. * The personal philosophy paper must be typed, double-spaced, following APA (6th ed. ) guidelines. It must be a minimum of 4 pages not including references or appendices. A minimum of 3 references must be used. No more than 1 of these can be electronic (internet) references.

Country Profile Research Paper Example | Topics and Well Written Essays - 1250 words
Country Profile - Research Paper Example Kenya is a country situated in the eastern coast of Africa and lies on the equator. The country hares borders with five countries; Tanzania lies to the South, Uganda lies to the West, South Sudan to the North-West, Ethiopia lies to the North part of Kenya while Somalia lies to the North-Eastern side of the country. (Pateman, 28). The Republic of Kenya has a total land area of 582,684 square km. (224,960 square miles) this is nearly the same size as Texas. The country got its name from Mount Kenya, which is quite a significant landmark and is the second highest mountain peak in Africa. The capital city of Kenya is Nairobi which is also the largest city in the Eastern Africa region. HISTORY The history of Kenya can be evidently be traced in the late 1800s when the Kenya-Uganda railways was being constructed by the British. Before then, the country was under the Protectorate of Sultan of Zanzibar who handed over the country to the Germans. The Germans later handed over the country to Im perial British East Africa which was in charge of constructing the railways going through the two countries (from Kenya to Uganda). Later on after the First World War and the completing of the Kenya-Uganda railways most of the British and European settlers in the early 20th century chose to settle in the country especially the central highlands this was in order for them to practice farming and grow coffee and tea. This in did not go down well with the locals as they felt their lands had been grabbed by the colonialists who had forbidden them from cultivating their lands by imposing huge taxes soon their houses and farming. The natives later started a resistance and they called the resistance Mau Mau Rebellion. From the October of 1952 to December 1959 the country was under the state of emergency and the Mau Mau fighters were engaged in guerrilla war against British rule. The capture of key Mau Mau fighters led to the war ending and thereafter the first direct elections for the Afri cans in the Legislative Council was held in the 1957 and in December 12th 1963 Kenya gained independence from Britain and also formed their first constitution on the same day. (YouTube) and (Pateman). One year later on 12th December 1964 Kenya was declared a republic. The first president of the country was Jomo Kenyatta who was the president until his untimely death in 1978. Daniel Arap Moi took over the country from 1978 until 2002 when a new political revolution led by the current president Mwai Kibaki won the election took over. In 2007 there was a massive ethnic unrest and political violence after different political parties accused the current president of rigging the election, this led to approximately more than 1000 people being killed and more than 60,000 displaced in the ethnic violence that was the aftermath of the flawed election. President Mwai Kibaki is expected to hand over the presidency in 2013. STRUCTURE OF GOVERNMENT Kenya is a democratic republic in the sense that the president is both the head of state and also he is the head of the government. The country has also a multi party system of politics. After the 2007 ethnic clashes caused by the elections, there has been constitutional amendments that enabled the sharing of the executive powers between the two political rivals in the government that is the President and the Prime Minister.

The economic condition, industry situation, cultural aspects, foreign investment strategies, government policies and risks need to be duly considered before entering in a foreign market. The economic development of China has become an issue of concern for several businesspersons. Before 1978, China was considered as centrally strategic and closed economy. Since then, China propelled numerous economic reorganisations. The central government had introduced the price and proprietorship inducements, inaugurated four Special Economic Zones (SEZs) in order to entice foreign investment, increased exports and imports of high-tech products among others. In China, the car industry is considered as one of the major sectors for industrial development and innovation efforts. In recent times, China has become one of the fastest car producers internationally. The car industry of China has continued to expand in spite of recent economic crisis. The report will describe the business systems of China and Germany and provide brief description about the methods for a German car company to conduct business in the Chinese market. Several factors such as business systems of the countries, foreign direct investment policies, and political aspects affecting the car industries, entry strategies, and recommendations for resolving the financial risks are considered in this report. 1.0 Analysis of National Business System and Cultural Condition in China & Its Impact on Automobile Industry China is one of the significant nations in Asian region in terms of business, cultural influence and population.

Economic Analysis Research Paper Example | Topics and Well Written Essays - 1000 words
Economic Analysis - Research Paper Example If we consider the production function where Q is the level of output, then Q = F (K, L) output is a function of both capital and labour, however to determine the optimum level of output that will maximize profit we will have to consider the cost of one unit of labour and one unit of capital and further consider the budgeted amount. Given that the cost of one unit of labour is 5 pounds and that the cost of one unit of capital is ten pounds and that our budget for both costs is 100 pounds then our optimum point will be determined as follows. The maximum amount of capital that can be purchased is 100/10 = 10 and the maximum amount of labour that can be purchased is 100/5 = 20, this information will help us determine the budget line. The next thing to consider is the isoquant, isoquant are curves that depict the possible output that is derived from two factors of productions which in this case are capital and labour The isoquant depicts the level of output that can be produced by different combinations of capital and labour, we determine the most optimum combination of capital and labour by determining the point where the budget line touches the isoquant, and therefore our most optimum levels of capital is C' and for labour its L' as shown above. Therefore the information that we need to collect is the unit cost of both capital and labour and the budgeted amount so as to determine the budget line and also we need information that will help us determine the isoquant. Question 2A When determining on what to produce either cooking pans or sinks we need to determine the cost of producing in terms of capital and labour for each item and also the market price of each item, given that the level of capital and labour are fixed in this case then we have to determine the optimum level of output for both products. This analysis will take the form of the consumer utility maximizing function where there exist two products, the utility function will represent the revenue collected by the firm and the two products which the consumer chooses will represent the two products produced by the firm. Example If in total we have 200 units of resources (both capital and labour) and that one sink requires 10 units of resources and one cooking pan requires 5 units of resources, then the maximum units of sink that can be produced is 200/10 = 20 and for the cooking pans is 200/ 5 = 40, The revenue curve will be determined by the market price of both products, it combines the possible amount of revenue that can be obtained by different combinations of cooking pans and sinks, the additional information needed therefore is the market price for both products and the amount of resources needed to produce each product. Question 2B In the long run the firm will tend to expand its production capacity in order to produce the optimum amount of both products, when the firm increases its capacity more products will be produced in order to realise economies of scale, however the average cost of production for the firm will decrease in the short run but will increase in the long run The long run and short run average cost curve The average cost curve will decrease in

Schools and court systems need to work together to tackle the problem Article
Schools and court systems need to work together to tackle the problem with trauncy and increase graduation rate - Article Example In order to prevent truancy one needs to find out the main reason behind truancy. Trujillo (2006) observes there are four primary causes behind truancy - student demographics, family characteristics, personal and psychological factors of the student, and climate and condition of family, school and society (Trujillo, 2006, p.74). Truancy and Dropouts School absenteeism and truancy is not always the same. There are various kinds of absenteeism and not all are grouped under the term truancy. Absence of a student from specific classes or in course of specific lessons or absence under parental consent would not fall under truancy. But, absence without any proper reason can be considered under truancy. If absence without good reason continues then there is a chance that students might incur poor academic results. Sometime bad relations with teachers or friends, involvement in unconstructive activities cause truancy. Once a young student starts believing that they are lagging behind his or her batch mates then the tendency of dropping out also increases rapidly as the latter option is more convenient than competing with others (Reid, 2005, p.59). Truancy and Juvenile Crime Truancy not only affects the young generation of the country but also hampers the growth of the population as well as development of the future generation. The direct and indirect effects of truancy always have an impact on individual, families, school and society in both short as well as long term. Zhang et.al (2007) observes that truancy destroys potential in youths. As a result they are headed for social isolation, criminal activities and education failure. Tendency of chronic absence in the early school days was associated with poor results in examination, isolation from friendsââ¬â¢ groups which ultimately caused dropouts in near future. In their review, they also pointed out that, truancy accounted for almost 26% of juvenile crime cases. According to their point of view, truancy can be cons idered as a first sign of trouble and most powerful reason for the delinquent behavior. Students who miss occasional classes were more inclined to get addicted to marijuana than those who never skip. They also mentioned that students who admitted being involved in truancy were, likely to be reported having committed serious crimes, and arrested owing to their involvement in serious assault. Generally when youths were absent from school, the rate of crime increased during the school going years only. Some truants were reported hanging out during school time, cruising in cars, and getting into trouble while skipping school (Zhang et.al, 2007, pp. 246-250). How Truancy Affect Dropout Dropouts from the school is directly associated with truancy. In the beginning of their school days, if students remain absent from school without any proper reason then they eventually consider this as a habit. White and Kelly observe the rates of dropout in USA were 11% among the age group of 18-24 in th e year 2008. They also pointed out the fact that rate of drop out was higher among the low income group which was 10.4% compared to that of the high income group (2.5%) in the same year. Truancy and absenteeism was the main reason behind this increased rate of drop out. Once it becomes a habit, students chose to drop out rather than catching up. In 2007 almost 9 percent students from the age group of 16-24 years dropped

Cluster- Biofuels in Colombia of issues and Recommendation Essay
Cluster- Biofuels in Colombia of issues and Recommendation - Essay Example While biofuel is not that clean as a source of energy, it can be readily produced in many areas with the right ingredients. In South America and Caribbean countries, Columbia is among the major producers of biofuel, but falls behind Argentina, Brazil, and Chile (Kyritsis 2001). Therefore, the biofuel industry continues to develop and become internationally competitive, though there are issues towards global competitiveness as discussed below. To analyze the issues in biofuel industry in Columbia, key lessons have been drawn from Michael Porterââ¬â¢s Cluster Diamond Model for analyzing competitiveness of industries or countries. According to Porter, there are four determinants of competiveness. One is a factor condition that involves analysis of a clusterââ¬â¢s factors of production and underlying natural resources. Two, demand conditions at home for the products and services with focus on sophistication and bargaining power of the buyers. Three, availability of related and supp orting industries that are globally competitive for a cluster to enjoy economies of scale. Four, firm strategy, structures and rivalry, and how it impacts on the overall competiveness of firms. More often, the influence of government in providing an enabling business environment is often added to this diamond (Rugman, 1996). The cluster competiveness analysis will be carried out along the five main factors. Assessment of supply factors in biofuel in Colombia shows that the country just like Guatemala has available residue for biofuel production (Kyritsis 2001). Bagasse mainly from sugarcane is available in large quantities to support mass production of bio-ethanol and biomass power production. Availability of farm land and plenty of feed stock due to large sugarcane production provides the necessary raw materials for production of biofuel. In addition, sugarcane factories and farms are concentrated within short distances meaning that cost of sourcing raw materials for biofuel produc tion is lower, making the commodity more competitive than fossil fuel. Support from sugarcane industries has helped independent biofuel producers. Availability of skilled manpower and research institutions is also a major boost as new methods and techniques keep on being generated. For example, improved production technologies have helped to increase efficiency in biomass conversion into ethanol and power generation in most factories across Colombia. Demand for biofuel in Columbia has continued to rise due to its wide applications in motor fuel. Analysts view the industry as perfectly elastic, with possibilities of growing bigger, given that only a small percentage of the fuel is being produced currently (Vertes et al., 2011). Competition from fossil fuel will also determine its growth trajectory; hikes in fuel prices will propel demand for biofuel and vice versa. The increased demand will trigger demand for corn, leading to an increase in corn prices. This move is expected to make biofuel producers to continue producing as long as they can make normal profit. Energy needs in transport related technologies have fuelled demand for biofuel, which has ended up attracting investments within and from outside the country. However, market analysts view the drive towards biofuel production as being politically motivated than being driven by market forces. Countries are seeking energy sovereignty to be in some control over energy prices. However, in either way, demand has

The Big Band Swing Era
The Big Band Swing Era It is said by historians, that they believe the Big Band Swing era dates back as early as the 1920s in early routes of jazz. It wasnt until the 1930s ranging into the 1950s, when the Big Band era became more known. Although it is called Big Band, its name can often be misleading. A Big Band consists of an orchestra with anywhere from six to as many as twenty-five musicians. Each band varies with the amount of musicians. The Big Band Swing era got its name based off of the smooth jazz beat and dance that is incorporated with it. The terms jazz band, jazz ensemble, stage band, jazz orchestra, society band and dance band can be used to describe a specific type of a big band. (Wikipedia: Big Band ) In 1932, a dance orientated band, Duke Ellington composed and recorded a song called It Dont mean a thing if it aint got that swing (The World Book Encyclopedia: J,K). The name of this song says a lot about how popular and important the Swing Era was too many people. This type of music was especially important during the time of World War II and leading America out of the Great Depression, by lifting morale. Today, The Big Band Swing Era is known for its unique components and style, which still holds a special place in hearts of millions of Americans. There are two famous Big Bands that stand out among several other Big Bands. They are the bands of Glenn Miller and Tommy Dorsey, who also played with his brother Jimmy. Glenn Millers band, also known as orchestra, was distinctive in a way that he combined the sounds of the clarinet with four saxophones. Glenn Miller said, A band ought to have a sound all of its own. It ought to have a personality. (The World Famous Glenn Miller Orchestra) Glenn miller was an excellent trombonist and believed very strongly in the music he performed. During the time of 1926-1938, he played the trombone in several bands including the band of Tommy and Jimmy Dorsey. In 1935, he recorded for the first time under his own name. Some of his well known hits were Sunrise Serenade, Moonlight Serenade and Wishing (Will Make It So). On April 13, 1940, he played at Sunnybrook Ballroom located here in Pottstown, Pennsylvania. It wasnt until the year of 1942, when he entered the U.S Army. While in the Army, he disa ppeared during an air journey leaving his music behind. The band of Tommy Dorsey was also known as the Dorsey brothers. The Dorsey brothers played in bands together as early as in the 1920s. Tommy Dorsey played both the trumpet and trombone. Throughout the Swing era, Tommy Dorsey was ranked among the top two or three big bands. His orchestra had about fifteen top ten hits in the late 1930s. The Dorsey Brothers broke the charts with their recording of Coquette. Also, with their recording with Bing Crosby called Lets Do It (lets fall in love), broke into the top ten. By this time, they had one of the hottest bands in the country. In 1935, Jimmy left Tommy to go on and play music on his own. The Dorsey brothers both passed away in the late 50s. As well as Glenn Miller, the Dorsey Brothers also played at the Sunnybrook Ballroom. Instruments found in big bands were trumpets, saxophones, trombones, drums, pianos, acoustic bass, and guitars. Instruments varied depending on the bands instrumentation of choice. Composers, arrangers and band leaders would switch things up and use more or fewer players in each section. The sections consisted of brass, string, percussion and vocal. Music of the big band was written in strophic form with the same phrase and chord structure repeated several times. In big band music, we also see a chorus that follows the twelve bar blues form, or thirty-two-bar following a (AABA) song format. Solos were also a part of most big bands. Swing dancing itself was one of the main components of the swing era. The music was represented in the dance, as dance partners (male) would twirl their partners around. Swing dancing is a lively dance which takes up a lot of energy. During this time period, swing dancing released tensions of the depression and the world in war times. This dance is intended for all ages. Some types of dances incorporated with the swing era are; Fox trot, Jitterbug and the Charleston. Big Band Swing still exists today. In fact it is becoming popular again, much like it was in the 30s throughout into the 50s. Swing Kat Entertainment located at the Ballroom on High in Pottstown, offers lessons on dances that strived during the swing era. On occasion, they have live Big Bands that perform; mostly bands that replay such music, like that of the Dorsey Brothers and Glenn Miller along with several other composers and songs. Sunnybrook Ballroom, also located in Pottstown has events that get the community together to re- shape and make todays generation aware, as well as to be a part of the swing era. An organization called The Philadelphia Swing Dance Society holds swing dancing events at the Commodore Barry Club located in Philadelphia. Sometimes big band can be heard playing on the radio on wxpns station 88.5. Many people enjoy this type of music and swing dance thats involved. The younger population also participates in events and enjoy getting their swing on. Many people enjoy reliving the swing era and look forward to community gatherings. Much like during the swing era, many people would come from all over the nation to attend dances and live performances. On April 15th at the Sunnybrook Ballroom there was a swing dance event that marked the 66th anniversary of World War II. During this event the eighteen piece Swing Fever Dance Band performed its annual USO Canteen Show, featuring music of Duke Ellington, Glenn Miller and the Dorsey Brothers (Staff). On Saturday April 16, 2011, I attended a live performance of a Big Band called the Slicked up Nines and swing dance at Swing Kat Entertainment in Pottstown. This band consisted of nine musicians all being men. Each band member was playing a different instrument. I thought this was an awesome experience to hear the instrumentation and witness people swing dancing for the first time. I myself was sucked into the rhythm of the music and felt the dance floor come alive. Instruments that the Slicked up Nines played were the following; drums, saxophone, bass, trumpet, baritone, guitar, finger tambourines and a wood block. The musicians were very involved with the music as well as the crowd. Two musicians, who were playing the saxophone, would swing their instrument from side to side. The two instruments that I feel that bring the big band alive are the saxophone and bass. The saxophone gives the music its jazz routes and the base sets the pace and rhythm for swing dancing. I was familiar with all the instruments I saw, other than the finger tambourines and wood block. These instruments were not included in the research in which I performed. Along with hearing music from the swing era, I was also fortunate to experience a few songs based off of west coast swing. The only new instrument I saw with this type of swing was the electric guitar. This gave the music a nice touch. Some songs that the Slicked up Nines performed were slower songs that used less percussion and more bass. One song that stuck out to me the most had lyrics that were catchy. This song had the words chew tobacco as a chorus. Not all of the songs that were played had vocal sounds in them. This was a friendly environment which had all kinds of age groups present. Many people dressed up in clothing which was worn during the swing era, as well as girls/ladies wearing dresses and men wearing dress shirts and cackies. The dance floor came alive as the band and swing dancers got fully involved in the music. The dance floor was built, so that it would bounce as people would dance on it. I found this to be a really cool feature and felt like I was back in the time period of the big band swing era. At times the music would get really fast as the men would swirl their partners around. Here, everyone danced with everyone and it didnt matter who, or where you were from. At the end of each song, the gentlemen would dip their partner. I thought that this was an interesting feature to swing dancing. Another component that I found to be interesting was that the songs would end real suddenly. This is much different than most of the songs we find today. Types of dances that I saw were the Fox trot, Jitterbug and the Charleston. Out of these three dances, I found that the Fox trot seemed a little more relaxed then swinging around the dance floor. Overall this was a fun clean event for everyone. I especially enjoyed the live band performance. During intermission, while the band took a break there was another event that took place. This was called the birthday circle. The person running the event called anyone to the center of the dance floor with a birthday in April. After this, the people remaining in the room gathered around in a circle. Those who were in the center would pick a partner and would switch dance partners. Everyone who wanted to dance with those who shared a birthday in April had a chance too. This was really cool and fun to watch. Here I saw for myself that the big band swing still exists to a small extent, due to many age groups that find interest in it. For anyone looking for a different taste of music, I would recommend it for anyone. For me this was a fun experience and I feel that the more that people come familiar with the swing era, the more popular it will continue to be today. The swing era is something that will remain in peoples hearts for many more years to come.

Revenge and Hatred in Sylvia Plaths Daddy Essay -- Sylvia Plath Daddy
Revenge and Hatred in Plath's Daddy The power of Plath's Daddy to threaten, shock and move the reader remains undiminished, years after it was written. To the unsuspecting reader, the experience of first reading "Daddy" is a confusion of discomfort, excitement and guilty pleasure, for the pleasures of revenge are said to be sweet, and this is a revenge poem of the first rank. Revenge upon whom? Father? Perhaps, more likely, upon her husband. And her aim was true, for if anything Plath wrote damaged Ted Hughes for posterity, "Daddy" is it. From this poem, we gather our indelible impressions of Hughes as a brute, a wife beater, a vampire, even an implied racist and murderer (if we extend the Hitler metaphor to its fullest implications) . . . on and on. The controversial Holocaust imagery can be directly linked to the period in which the poem was written. In 1961, the entire world was riveted by the Jerusalem trial of Nazi SS Lieutenant Colonel Adolph Eichmann (who was executed in 1962, a few months before "Daddy" was written). This was the first televised trial in history, an...

President Bill Clinton :: Biography
Introduction This paper will discuss the life and work of William Jefferson Blythe III @ Bill Clinton. It will summarize his early life, his rise in American politics, his achievements as the leader of the world's superpower, his extremely infamous affair and his post-presidential career. Early Life The 42nd president of the United States of America was born on August 19, 1946 in Hope, Arkansas. Named after his father, who died 3 months before he was born, he was raised by his mother, Virginia Dell Cassidy and later his step-father, Roger Clinton. He assumed his last name "Clinton" legally when he was 14, according to Bill, his father was an alcoholic who regularly abused his mother and half-brother, Roger Jr. Bill Clinton excelled while in high school, both academically and through extra-curricular activities. He was a talented saxophonist and at a point, considered dedicating his life to music. However, his interest in politics surfaced after a class trip to the White House to meet the current president then, John F. Kennedy. He then pursued a Bachelor of Science, majoring in Foreign Services at Georgetown University. He won a scholarship to University College, Oxford. After Oxford, Juris Doctor Degree from Yale Law school. It was here that he met his wife Hilary Rodham. They wedded in 1975 and were blessed with a daughter, Chelsea in 1980. Political Career In 1978, Bill Clinton was elected Governor of Arkansas. He was defeated for a second term due to an unpopular motor vehicle tax and anger by the public over escaped Cuban prisoners. However, in 1982 he won back the post and it was during his time as the 52nd Governor of Arkansas that he began to rise in great heights. He was elected as president in 1992 when he won against George H.W. Bush by 43% of the votes. During his administration, the U.S enjoyed the most peace and economic well being than any other time in history. He achieved budget surplus, achieved the lowest unemployment rate of modern times, the lowest inflation rate in three decades, the highest home ownership in the country's history, dropping crime rates in many places, and reduced welfare rolls. The States had five consecutive years of real wage growth, after declining 4.3 percent during the two preceding administrations. This represented the longest consecutive increase since a period in the 1960's and 1970's. Record breaking home ownership at 2/3 of households being homeowners with minority homeownership also reaching new heights represented another of his great achievements.

GSP
Previous report have shown that following an SE, reactive astrocytes become hypertrophic (increasing the expression of intermediate filament proteins), and develop longer and thicker processes (Robel et al., 2015), In this study, astrocytic reaction observed in the GSP or DZP treated CSE is moderate (Plate 4.13.5b), due to the fairly stabled morphology. This could probably be linked to a reduced excitotoxicity or attenuated ROS by GSP or DZP within the hippocampus attributable to GSP treatment especially. It therefore becomes a suggestive evidence from this study that astrocytic reaction in CSE treated with either GSP or DZP is an adaptive type of astriogliosis (a defensive reaction aiming to restore homeostasis). The functional and morphologic changes astrocytes undergo in the GSP or DZP brain and during CSE may have a dual nature based on the underlying pathophysiological characteristics. On the one hand, reactive astrogliosis can occur as a compensatory mechanism following damage to the nervous system and lead to the reduction in excitability (Vargas-SÃ ¡nchez et al., 2018). In this study, there was intensification of astrocytic proliferative in the CSE + NS at 7th day post CSE. This is in consonant with the findings of Gibbons et al. (2013) that in early stages of SE there is no marked intensification in astrocytic proliferation, while at later stages, there is a rapid increase in the number of astrocytes. Although astrocytes have the capacity to proliferate just after an SE, the reported small number of new cells suggest that in models of SE reactive astrocytes are comprised mainly of the resident astrocytes present before the insult (Gibbons et al., 2013). Conclusion The major consequential effects of CSE is on higher order behaviour, most especially on indices of learning and memory which is mainly controlled by the hippocampus. These effects of CSE stemmed from reduction in percentage body weight gain, attenuation in the relative hippocampal weight to the brain, decreased spatial and object recognition memory. However, memory impairment observed in this study was attributed to alteration in the cholinergic neurotransmitters, increased excitotoxicity, pro-oxidant/ antioxidant imbalance which led to exacerbation of oxidative stress of the hippocampus, hippocampal atrophy and necrosis, astriogliosis, and generation of abnormal granule cells in the hillus of the dentate gyrus, All these dysfunction were significantly attenuated by GSP treatment, the effect that was better tolerated than that of a conventional anticonvulsant drug- DZP. It is therefore concluded that GSP can be used is a better agent in the treatment of CSE due to its attenuation in memory impairment and insignificant adverse effects. Recommendation The principal goal of CSE treatment is the termination of seizure with little or no attendant on-toward side effects. It is evident from this study that apart from the fact that GSP (20 mg/kg or 10mg/kg) attenuated hippocampal excitotoxicity and astriogliosis following CSE, it also posed no significant side effects on the indices of learning and memory. This study therefore recommends further experimental research on the anticonvulsant and neuroprotective activities of GSP.

Lev Vygotsky
Down through the years psychologists and individuals involved in education have developed and investigated different theories about how children learn. To understand how children receive and use information is of great value to parents, teachers and indeed society in general as the children of today are tomorrowââ¬â¢s adults and our society will not develop if our children cannot learn effectively. In this essay I will discuss the theories of Lev Vygotsky as I believe his work has become the foundation for a lot of our modern day theories and concepts in regard to a childââ¬â¢s cognitive development. Lev Vygotsky was born in Russia in 1896 during the Russian Revolution and his works only came to the attention of the western world when they were published in 1962. Vygotsky died quite young and a lot of his research was unfinished however his work was continued by his students and followers alike. Vygotskys theory of Socio-cultural or Social Development as it is also known was the building block for the concepts and stratagies now used in our pre-schools and schools today. Unlike Piaget who believed that development preceeds learning, Vygotsky believed that to develop, a child must learn first. He rightly believed that the most effective learning comes from a childââ¬â¢s social interaction in society and the cultural they are reared in. Social factors and culture contribute to a childââ¬â¢s cognitive development. Vygotsky believed that society gave a child various cultural tools which enabled learning, language being one of the most important. Language is the primary form of interaction and through language a child can communicate thoughts, emotions, opinions and ideas and develop friendships. A childââ¬â¢s level of language skills can and most likely will effect all other aspects of their development both personally and academically. Through my research I see that Vygotskys concept, the zone of proximal development, which is Vygotskyââ¬â¢s term for the range of tasks too difficult for children to master alone but which can be learned with the guidance and asistance of adults or more skilled chilren, is widely used today in learning institutions worldwide, its concept is used in most subjects and used very effectively with a broad spectrum of students, ranging from disadvantaged, special needs, and ââ¬Å"giftedâ⬠students to adults. Within this concept Vygotsky talks about ââ¬Å"Scaffoldingâ⬠which basically means changing the level of support as the student becomes more capable in a task or subject. Another concept which is interlinked with the above is The More Knowledgeable Other (MKO). The MKO refers to anyone who has a better understanding or a greater ability than the student, in respect to a particular task or concept. The MKO is normally thought of as being a teacher, coach, or older adult, but the MKO could also be peers, a younger person, or even computers. As I read and study these concepts I can clearly see their incorporation into our education system today compared to when I was a child starting out in school forty years ago. Although systems where evolving gradually, there were very different opinions and methods in place regarding education. Lev Vygotsky: Lev Vygotsky (November 17, 1896 ââ¬â June 11, 1394) was a Russian psychologist. Vygotsky was a pioneering psychologist and his major works span six separate volumes, written over roughly 10 years, from Psychology of Art (1925) to Thought and Language [or Thinking and Speech] (1934). Vygotsky's interests in the fields of developmental psychology, child development, and education were extremely diverse. Vygotsky's theories stress the fundamental role of social interaction in the development of cognition Vygotsky, 1978), as he believed strongly that community plays a central role in the process of ââ¬Å"making meaning. He argued, ââ¬Å"learning is a necessary and universal aspect of the process of developing culturally organized, specifically human psychological functionâ⬠(Vygotsky 1978, p. 90). Vygotskyââ¬â¢s theory differs from Piaget in three different ways. 1. Social interaction plays a fundamental role in the process of cognitive development. In contrast to Jean Piag etââ¬â¢s understanding of child development, Vygotsky felt social learning precedes development. 2.The more knowledgeable other refers to anyone who has a better understanding or a higher Ability level than the learner, with respects to a particular task, process, or concept. MKOââ¬â¢s Can be peers, a younger person, teachers, coaches, older adult, or even computers. 3. The zone of proximal development is the distance between a studentââ¬â¢s ability to perform a task under adult guidance and/or with peer collaboration. It is also the studentââ¬â¢s ability to solve problems independently. ââ¬Å"According to Vygotsky, humans use tools that develop from a culture, such as speech and writing, to mediate their social environments.Initially children develop these tools to serve solely as social functions, ways to communicate needs. Vygotsky believed that the internalization of these tools led to higher thinking skills. â⬠(http://www. learning-theories. com/vygotskys-soci al-learning-theory. html) In modern day terms, Vygotsky would be a facilitator. Teachers and students collaborate in learning and practing four key skills (summarize, question, clarify, and predict). Teaching and learning is a two way street. You have to be able to interact with the student.This simply means you have to know your student. Teachers have to know where their students are educationally to get them to move to the next level. Then we have to cater our teaching to meet the needs of the learners. I believe that a teacher must be able to relate to their student. For example, a teacher that had both parents that is wealthy. That teacher shouldnââ¬â¢t expect his/her students to behave as he/she did as a student at that age. You have to realize that there are differences and make accommodations.A child from a wealthy home and a child from a single parent working class home canââ¬â¢t be taught using the same method. The backgrounds are too different. References Vygotsky, L . S. (1962). Thought and Language. Cambridge MA: MIT Press. Vygotsky, L. S. (1978).

A sense of self-direction Essay
There may be personal information that you want considered as part of your admissions application. Write an essay describing that information. You might include exceptional hardships, challenges, or opportunities that have shaped or impacted your abilities. à à à à à à à à à à à Discipline is one of the issues being faced by most teenagers anywhere in the world. A lot of these people find it hard to inculcate in themselves the self-control and self-responsibility they ought to have. A sense of self-direction is one of the many ways that teenagers can employ to have that bite of discipline in their systems. à à à à à à à à à à à I am a seventeen year old and a non-religious middle class man. Unlike many other men of my age, I am proud to say that I am well-disciplined. And I owe much of this to sports. Sports actually helped me and still continue to help me become a disciplined man, especially when I stepped into high school. A lot of my wonderful memories and lessons in life are attributable to my experiences as a person inclined in many sports. For four years now, I am part of the tennis varsity team of my school, of which I was given the honor to rank third in state in my small league. That was one of the best days I ever had in my sports life. Days of training and practice were all paid off after receiving such recognition. This award does not stop me from training and practicing more as days pass by. Instead, this achievement inspires me to do a lot better than I did so I can be the best tennis player I can be. It inspires me to do more so that I can be able to become more of a tennis playerâ⬠¦more of a person. With my inclination in sports, I learn to be focused on things that really matter. I do not waste my time to non-productive activities, thus I become productive as a person. With sports, I learn how to be a team player, which would really help me a lot by the time I have my own career in whatever field I choose. I know and I believe that learning how to be in a team, may it be as a leader or just an ordinary member, will surely get things done with ease and victory. Tennis games and practices are training grounds for me not just to become the best tennis player but more to become the best person that I can be. à à à à à à à à à à à Aside from tennis, I also am interested to other sports like basketball and soccer. I play for these sports during my sophomore and junior years. I enjoyed every single day I spent for practices. I find a different sense of fulfillment whenever I play sports. It makes me happy to be with my teammates and play not just the games on court but also the game of life. Sports have become special parts of me because through them, I feel and believe that I became a much better person than I ever was before. à à à à à à à à à à à Surely sports leave a big impact to my life. I would not have learned become a disciplined, mature, responsible, and productive person if not for it. I would never have developed my interpersonal and social skills if I was not part of a team. I would never have been the person I am now if I become attached to other activities aside from sports.

Biological Theory of Aging
Biological Theory of Aging Tick tock, tick tock, what's that sound? According to this theory, it's your biological clock, ticking away at a predetermined rate. This theory says that DNA, the cells' genetic material, holds the key to your planned demise from day one. While this aging theory appears fatalistic on the surface, remember that biology is not destiny. You can't change your genes, but you can slow the march of time with better eating habits and regular exercise. Your body produces hormones that help regulate myriad functions, including growth and behavior, reproduction, and immune function.In your youth, hormone production is high, but as you get older, hormone levels drop off, causing declines in the body's ability to repair itself and to keep functioning in top form. Working cells produce waste. Over time, cells make more waste than they can possibly get rid of, which may wreak havoc on their ability to function and slowly lead to their death . Lipofuscion, or age pigment, is one of the waste products found primarily in some nerve and heart-muscle cells. Lipofuscin binds fat and proteins together in the cells.It accumulates over time and may interfere with cell function. The protein collagen is at the heart of this theory. Collagen, akin to the body's glue, is one of the most common proteins making up the skin, bones, ligaments, and tendons. When we're young, collagen is pliable. But with age, collagen becomes more rigid, and it shrinks. That's why your skin is less elastic than before (Alston, 2008). Aesthetics aside, cross-linking may block the transport of nutrients into cells as well as obstruct waste-product removal.Free radicals are destructive marauders roving your body, ready to pounce on healthy cells. They are produced as part of the millions of chemical reactions your body performs to sustain life (Ward, 2012). Your body also makes them in response to environmental toxins such as excessive amounts of unprotected sunlight and smoking. Free radicals oxidize your cells (think rusting metal). As unbalanced, volatile oxygen molecules, they sacrifice healthy cells to make themselves more stable. Free radicals destroy or alter DNA, the cell's genetic blueprint, and disrupt many other cell functions.Free radicals may kill cells as a result of their marauding, or they may give rise to mutant cells that can lead to chronic conditions including cancer and heart disease. Fortunately, the body maintains a sophisticated defense system against free radicals. Unfortunately, our defenses wane with time, and cell damage ensues (Ward, 2012). This theory could also be called The Use It and Lose It Theory. The idea is that use, and overuse, of your organs pushes them to the brink of destruction.A poor diet, too much alcohol and cigarette smoking are thought to accelerate natural wear and tear. With age, the body is less able to repair itself. How does wear and tear occur? Free radicals, which inflict cellular damage, may be culpable. Sim ilar to the wear and tear idea, this theory says you are born with a certain amount of energy. If you live ââ¬Å"fast,â⬠you die young, because you use up your energy reserves sooner. ââ¬Å"Laid-back people,â⬠who suffer from less stress and take life easier, would live longer should this theory prove correct (Ward 2012).A strong immune system is your body's most important defense against germs and toxins. White cells engulf and destroy potential pests such as bacteria and viruses. And they manufacture antibodies, the ââ¬Å"soldiersâ⬠that patrol the bloodstream, attacking and disarming any substance they don't recognize as the body's own. Problem is, the immune system becomes less efficient with time, and fewer antibodies are produced, increasing your infection risk. What's more, the body may turn on itself by producing antibodies that destroy its own tissue.When that happens, autoimmune disease, such as lupus and rheumatoid arthritis, is the result (Alston, 2008) . Although we still do not completely understand the process of aging, we do know quite a lot about it. Sometimes it may be time for the clock to just get new batteries or perhaps the clock has stood the test time and became an antique. Bibliography Alston, Maude H. Basic Gerontology.

Parking Problem At Florida State University Essay
Parking Problem At Florida State University - Essay Example By Improving the potential circulation and movement of these pathways and also eliminating various pathways which make the procedure cumbersome for pedestrians, will certainly improve the overall process. It is also evident that landscaping, protected walkways, and pathways and also adequate lighting facilities will help in enhancing the overall pedestrian experience and will improve the parking facilities. Students having bicycles or motorbikes will also be facilitated if the bicycle paths are made. An important thing to note, however, is that a bike path may not be highly convenient or effective if it is inconsistent with its procedures. According to Lyons, a bike pathway which can only create lanes of roadways which can merely switch to a sidewalk will merely create problems for potential riders and will also create conflicts and other problems for the pedestrians. By evaluating and analyzing these highly important procedures, Florida University would certainly have a concrete vie w of where we can focus on our efforts as well as all our technical resources. But, the higher authorities of this institute could be blamed for the occurrence or potential occurrence of such administrative shortages. The core requirement in this regard is the creation of a mutual alliance between teachers, students, school administrative authorities and all other stakeholders involved. The higher authorities in the university have to understand how essential a spacious parking space would be for students and other school staff.

Origens Allegorical Interpretation Essay Example | Topics and Well Written Essays - 3250 words
Origens Allegorical Interpretation - Essay Example In this paper I will look into the history of Allegorical interpretation. Moreover I will precisely study why Origen chose to interpret allegorically, what were the factors that influenced him to do so, the times and circumstances when he studied the holy words and also whether his approach was successful or not. Origen was born to a Christian family in Alexandria in either year 185 or 186. His father was believed to be a prosperous and prominent man, who gave his son with schooling that was equally Hellenistic as well as Christian and was based on the learning of the standard literary works of olden Greece and the Holy Bible. Hence he grew up as together as a learned Greek and a committed Christian. This combat education definitely caused somewhat of an inside stress in Origen as he sought to settle his pledge to Christian belief and the Bible with the Hellenistic viewpoint he was educated. From the outlook of Hellenism, Christianity was slightly more than an additional barbarous false notion and the Bible represented a substandard set of texts that were not worth stern thought from the viewpoint of Greek visual standards2. Origen was not the initial one to face this anxiety, and he was proficient to find out from preceding Jewish and Christian whereabouts with Hellenism, mainly Platonic philosophy, in his individual effort to confirm the Bible and its ideas in the framework of the Greek intellectual surroundings. Undeniably, as a student at the school in Alexandria, it is probable that some of his instructors were from Clement of Alexandria, and was also well known for his challenge to communicate Christian teaching to Greek philosophical reflection5. Out of Origen's many works two are valued most in the history of the initial church and Christian thinking. "On First Principles" is a structured and methodical version of Origen's theological and truth-seeking arrangement relating to God, foundation, the different Logos of God, Jesus Christ and salvation. The second one that is "Against Celsus" is a comprehensive remorseful justification of Christian belief written in opposition to the analysis of the Roman thinker Celsus. In this book Origen tries to reveal the supremacy of the teaching and insight of the Bible over against that of the famous Greek philosophy. Allegory Before I proceed to explain the history behind Origen's allegorical interpretation, I would like to mention the formal definition for the term allegory as given by scholars. The word "allegory," is a derivative from the Greek language, from the word "alla," which refers to "other," and another term "agoreuo," which means "to declare." It initially referred to a form of dialogue that Cicero put forward as a 'incessant flow of similes.' Allegory is a style of communication in which one thing is explained by another 5. Allegory varies from the parable, as it is a more organized appearance of the diverse features of the thought that it demonstrates, and also in its contents which are apprehensive with the explanation of hypothetical truths rather than realistic exhortation. The History Of Allegorical Interpretation Allegorism was not a new concept at all. Infact it was well-known in

Part I Managing Public Organizations and Employees Article
Part I Managing Public Organizations and Employees - Article Example s terry Green and Eric Thomas are non Indian who are outstanding actors because the land in question is an Indian reserved land and there are persons like Richard Tall grass who is an official in the land. A claim has been brought forth regarding an Eric Thomas dumping toxic waste which was confirmed by relevant personnel that the substance was indeed toxic to the environment. The person the claim has been brought against is non-Indian who owns land in the reservation. Most of the reservation is currently under the ownership of the whites. The claim was brought to the director of the EPD Terry Green who took action to cease the operations by Eric Thomas of dumping the waste material (Elshtain & Cloyd 1995). The primary problem in these establishments is that there is a dumping problem to the residents of the reservation area. Despite this being so, there are also other problems eminent aside from the main one. The secondary issue then is the fact that there is no body that has proper jurisdiction as to the issues arising in the reservation area With these issues having risen in the reservation land, the source of the dumping is people who are non-Indian who can be said to be downgrading the value of the land. There is an act which had been established namely the Allotment act of 1887, this act contains the provisions of the people whom the lands here were issued. There are issues such as the health issue which can be caused from the dumping being done by Eric Thomas which should be put to consideration. The constraints here is that the people involved in the dumping of toxic waste are not co-operative with the authorities The first course of action is enactment of law correlative with the ones that are already active. The law should directly direct the issue of land degrading through dumping and other issues. The second course of action is put bodies who act as intermediaries between the people in the land who are non white and the Indians in the reservation

It is characterized by the failure of the spleen to function optimally even in the first months of birth that usually leads to overwhelming pneumococcal infection, usually at 20% mortality rate for patients under 5 years old (Overturf, 1999). Since access to health care is seen as one of the main problems for SCD patients, it becomes important to identify ways to mitigate its most immediate or important effect on patient which is pain described as chronic, acute or both. Pain management is an important element of care for SCD patients. It is with the related goal to identify pain treatment, control or reduction that this study will proceed. Quality of life is an overarching goal for patients even with those genetic disorders. Pain reduction is usually related to increased patient satisfaction and improved quality of life even in conditions of disease and chronic pain. Chronic pain has been reported by people with SCD even when they now have chances of living a longer life. Use of pai n relieving, controlling and treatment method for patients with SCD is then important for the determination of quality delivery of health care services. Various methods are employed in HMO settings to treat SCD patients in reducing, controlling, and treating pain. These are influenced by the pain assessor, patient access, affordability, availability, knowledge and orientation of administrator, and other factors that may be present during prescription or administration. This research will identify the methods used at Kendall Regional Hospital in-patient section, their frequency of use, what is the most popular method preferred, and determine the immediate effect of employing such methods. -Purpose of the study The purpose of this study is to

How the existence of cheat codes could hurt Johnsons argument about Case Study
How the existence of cheat codes could hurt Johnsons argument about video games - Case Study Example Some of these regions are in dire need of security and other resources that are basic for human existence like food, shelter and clothing. The UN is has presence in most parts of the world with different organizations, within it, having key roles to play in promoting peopleââ¬â¢s wellbeing and improving security. Though the initial charter does not state that the UN should participate in peace keeping, the organization has been influential in keeping peace, for example, in Eastern Europe and Africa. As such, the UN participates in prevention of recurring wars and any spread of warfare to other areas. Therefore, the United States should take the UN as an asset that enhances development and sustainably. The UN has been influential in promoting peace, sustainability and development in many regions which are vital in the economic and political development of the US and the whole world. The most notable peace keeping missions in which the UN was heavily involved are centered in the Mid dle East. There has been a recurrent eruption of war in the Middle East, which has affected the worldââ¬â¢s economy. Many countries in the world are affected by these war eruptions, which is a disadvantage to the development of many economic regions. The Middle East is known to have massive oil deposits. It is explicitly reflected that the management of worldââ¬â¢s oil deposits is vital to the world economy. As such, any detrimental effects in these nations will affect the world oil prices and thus increase the cost of production the world over. When there instability in this region the first effect is always reduced oil production followed by increased oil prices. The countries in the Middle East are likely to record unfavorable balance of trade as their exports reduce during war or instability. This is an issue that directly affects the US as it is the single-most largest consumer of oil and related products. Were it not for the UN, the Middle East case would have been much worse than it is today. Similarly, diminished trade between the US and the Middle East countries has a direct impact on the economy of the US. If the wars in the Middle East are to continue for the next decade, the economy of the US will be worst affected. Therefore, the indulgence of the UN should be considered an asset as it strengthens the peaceful coexistence in the region. If these indulgences started after the WWI, there would be peace in this region. The activities of the UN should be enhanced to make the organization have increased positive influence worldwide. In addition to this, the UN has been influential in helping Cyprus. This nation has been adversely affected and the UN has stepped in to solve the situation. 6. Evaluation of the United Nations in the Middle East In the recent times, Syria has experienced unrest which led to the displacement of over 350, 000 refugees. As per the year 2012, Iraq recorded the highest number of refugees coming from the country, others ge tting into the country and many others displaced internally. According to statistics, the number of refugees from Iraq was recorded at 1.4 million while internally displaced persons were recorded at 1.3 million. This is a large number of people that need protection and other humanitarian assistance. The UN has since established its mission in the area to help these persons. According to the UN strategy in 2013, the organization is hosting 148, 000 refugees which are particularly from Syria. The r4ecent financial report states that the UN has used a total of 453,386, 000 USD. The UN has been effective in maintaining peace in the Middle East from its ongoing peace missions.

Factors other than technology that influenced military innovation Essay
Factors other than technology that influenced military innovation during the Interwar Period - Essay Example Europe was immensely affected by the devastation of the First World War while North America affected by the great depression in 1929. The worldwide depression contributed to the growth of Nazism in Germany which resulted in World War 2. The military technology of the interwar period provided ample promise for innovation, but did not determine the state of change. In many cases state of the art technology would not support operational concepts developed by military visionaries. (Williamson Murray, Allan R Millet, p.342) Civilian timidity, insufficient intelligence, and lack of political guidance contributed immensely to the lack of military innovation during the interwar period. Civilian participation is important in political and technological processes. In Britain military professionalism countered civilian curiosity; the committee system diffused arguments and sharpened pessimism rather than encouraged debate on defence options. (Williamson Murray, Allan R Millet, p.361) The general public during this period was not aware of the importance of military innovation. They had many other things to discuss like the depression, and they never took military innovation as a serious thing. They were already witnessed the drastic results of a world war and they thought the military innovations may result in another world war. The civilians concluded that the military operations are for destructive purposes only and they failed to recognize the need of defence and such attitudes of the civilians retarded the military innovation process. In the United States, civilian-military political collaboration arose in the institutionalized conflict between the Presidency and Congress over domination of military policy. (Williamson Murray, Allan R Millet, p.362) The political leaders also kept different views on the need of military innovation. Because of these conflicts among the parliamentary members, the most of the military innovation processes failed to get the
Under Treatment of Pain in the Elderly Essay Example | Topics and Well Written Essays - 1000 words
Under Treatment of Pain in the Elderly - Essay Example Under Treatment of Pain in the Elderly Roy and Thomas (1986) conducted a survey regarding chronic pain in the elderly. They conducted their study on 132 participants who were either residents of the nursing home or were attending hospital programs. They found that 83% of the patients stated that they, most of the time, suffered from pain which mainly was due to damage in connective tissue. 84% of the participants who reported pain were using analgesics and 16% were not receiving any kind of treatment at all. The participants reported that they had been feeling pain for many years. Researchers found that majority of participants reported low levels of pain accompanied with depression, and none of the participants was being treated for depression. According to the researchers, ââ¬Å"there may be an inclination to underestimate the prevalence and intensity of pain in the elderlyâ⬠(p.513). Bernabei et al. (1998) studied the treatment of pain and pain management in the elderly patients who were suffering from cancer and were admitted in nursing homes. Theirs was a retrospective, cross-sectional study conducted in 1492 nursing homes located in 5 different states. The population size was 13625 and the participants were 65 years and older. They found that among the total population size, 4003 patients were those who reported daily, regular pain 16% of whom were receiving a WHO level 1 drug, 32% were receiving a WHO level 2 drug, and 26% were those who were being treated with morphine only (p.1880). They also found that as the age grew older, the opportunities for pain treatment became fewer so much so that the patients who were over 85 years did not even receive an analgesic dose. Their study concluded that ââ¬Å"Daily pain is prevalent among nursing home residents with cancer and is often untreated, particularly among older and minority patientsâ⬠(p.1877). Ahmad and Goucke (2002) conducted their research on the treatment of neuropathic pain in the elderly and pain management strategies. Accor ding to them, neuropathic pain is the hardest to identify and manage in the elderly without inflicting any adverse effects on them, and this leads to its undertreatment. They state that it is important to incorporate non-drug pain management options in the treatment process to reduce the adverse effects that medication inflicts on the elderly. These options may include psychotherapies, exercises, improved life style, and environmental modification. According to them, combined strategies and mixed treatments can prove to be more helpful in treating pain in the elderly. Gagliese and Melzack (1997) also support the fact that the older adults usually receive inadequate pain management. They state there can be three reasons for this: ââ¬Å"lack of proper pain assessment; potential risks of pharmacotherapy in the elderly; and, misconceptions regarding both the efficacy of non-pharmacological pain management strategies and the attitudes of the elderly towards such treatmentsâ⬠(p.3). Supporting the fact that pain treatment becomes less likely because the elderly do not express their pain, there is a research by Manfredi et al. (2002) who studied assessment of pain through facial expressions in the elderly suffering from dementia. They evaluated 9 patients who had ââ¬Å"decubitus ulcers associated with reports of pain during dressing changesââ¬

Blood pressure Essay Example for Free
Blood pressure Essay Blood pressure (BP), sometimes referred to as arterial blood pressure, is the pressureexerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, blood pressure usually refers to thearterial pressure of the systemic circulation. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.[1] The blood pressure in the circulation is principally due to the pumping action of the heart.[2] Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles.[3] Gravity affects blood pressure via hydrostatic forces (e.g., during standing) and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins.[2] The measurement blood pressure without further specification usually refers to the systemic arterial pressure measured at a persons upper arm and is a measure of the pressure in the brachial artery, major artery in the upper arm. A personââ¬â¢s blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimetres of mercury (mmHg), for example 120/80. The table on the right shows the classification of blood pressure adopted by the American Heart Association for adults who are 18 years and older.[4] It assumes the values are a result of averaging blood pressure readings measured at two or more visits to the doctor.[6][7] In the UK, blood pressures are usually categorised into three groups: low (90/60 or lower), high (140/90 or higher), and normal (values above 90/60 and below 130/80).[8][9] Normal range of blood pressure While average values for arterial pressure could be computed for any given population, there is often a large variation from person to person; arterial pressure also varies in individuals from moment to moment. Additionally, the average of any given population may have a questionable correlation with its general health; thus the relevance of such average values is equally questionable. However, in a study of 100 human subjects with no known history of hypertension, an average blood pressure of 112/64 mmHg was found,[10] which are currently classified as desirable or normal values. Normal values fluctuate through the 24-hour cycle, with highest readings in the afternoons and lowest readings at night.[11][12] Various factors, such as age and sex influence average values, influence a persons average blood pressure and variations. In children, the normal ranges are lower than for adults and depend on height.[13] As adults age, systolic pressure tends to rise and diastolic tends to fall.[14] In the elderly, blood pressure tends to be above the normal adult range,[15] largely because of reduced flexibility of the arteries. Also, an individuals blood pressure varies with exercise, emotional reactions, sleep, digestion and time of day. Differences between left and right arm blood pressure measurements tend to be random and average to nearly zero if enough measurements are taken. However, in a small percentage of cases there is a consistent difference greater than 10 mmHg which may need further investigation, e.g. for obstructive arterial disease.[16][17] The risk of cardiovascular disease increases progressively above 115/75 mmHg.[18] In the past, hypertension was only diagnosed if secondary signs of high arterial pressure were present, along with a prolonged high systolic pressure reading over several visits. Regarding hypotension, in practice blood pressure is considered too low only if noticeable symptoms are present.[5] Clinical trials demonstrate that people who maintain arterial pressures at the low end of these pressure ranges have much better long term cardiovascular health. The principal medical debate concerns the aggressiveness and relative value of methods used to lower pressures into this range for those who do not maintain such pressure on their own. Elevations, more commonly seen in older people, though often considered normal, are associated with increased morbidity and mortality. Physiology There are many physical factors that influence arterial pressure. Each of these may in turn be influenced by physiological factors, such as diet, exercise, disease, drugs or alcohol, stress, obesity, and so-forth.[20] Some physical factors are: â⬠¢ Volume of fluid or blood volume, the amount of blood that is present in the body. The more blood present in the body, the higher the rate of blood return to the heart and the resulting cardiac output. There is some relationship between dietary salt intake and increased blood volume, potentially resulting in higher arterial pressure, though this varies with the individual and is highly dependent on autonomic nervous system response and the renin-angiotensin system.[21][22][23] â⬠¢ Resistance. In the circulatory system, this is the resistance of the blood vessels. The higher the resistance, the higher the arterial pressure upstream from the resistance to blood flow. Resistance is related to vessel radius (the larger the radius, the lower the resistance), vessel length (the longer the vessel, the higher the resistance), blood viscosity, as well as the smoothness of the blood vessel walls. Smoothness is reduced by the build up of fatty deposits on the arterial walls. Substances called vasoconstrictors can reduce the size of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitroglycerin) increase the size of blood vessels, thereby decreasing arterial pressure. Resistance, and its relation to volumetric flow rate (Q) and pressure difference between the two ends of a vessel are described by Poiseuilles Law. â⬠¢ Viscosity, or thickness of the fluid. If the blood gets thicker, the result is an increase in arterial pressure. Certain medical conditionscan change the viscosity of the blood. For instance, anemia (low red blood cell concentration), reduces viscosity, whereas increased red blood cell concentration increases viscosity. It had been thought that aspirin and related blood thinner drugs decreased the viscosity of blood, but instead studies found[24] that they act by reducing the tendency of the blood to clot. In practice, each individuals autonomic nervous system responds to and regulates all these interacting factors so that, although the above issues are important, the actual arterial pressure response of a given individual varies widely because of both split-second and slow-moving responses of the nervous system and end organs. These responses are very effective in changing the variables and resulting blood pressure from moment to moment. Moreover, blood pressure is the result of cardiac output increased by peripheral resistance: blood pressure = cardiac output Xperipheral resistance. As a result, an abnormal change in blood pressure is often an indication of a problem affecting the hearts output, the blood vessels resistance, or both. Thus, knowing the patients blood pressure is critical to assess any pathology related to output and resistance. Mean arterial pressure The mean arterial pressure (MAP) is the average over a cardiac cycle and is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP),[25] Curve of the arterial pressure during one cardiac cycle The up and down fluctuation of the arterial pressure results from the pulsatile nature of thecardiac output, i.e. the heartbeat. The pulse pressure is determined by the interaction of thestroke volume of the heart, compliance (ability to expand) of the aorta, and the resistance to flow in the arterial tree. By expanding under pressure, the aorta absorbs some of the force of the blood surge from the heart during a heartbeat. In this way, the pulse pressure is reduced from what it would be if the aorta wasnt compliant.[26] The loss of arterial compliance that occurs with aging explains the elevated pulse pressures found in elderly patients. The pulse pressure can be simply calculated from the difference of the measured systolic and diastolic pressures,[26] Armââ¬âleg gradient The armââ¬âleg (blood pressure) gradient is the difference between the blood pressure measured in the arms and that measured in the legs. It is normally less than 10 mmHg,[27] but may be increased in e.g. coarctation of the aorta.[27] Vascular resistance The larger arteries, including all large enough to see without magnification, are conduits with low vascular resistance (assuming no advanced atherosclerotic changes) with high flow rates that generate only small drops in pressure. The smaller arteries and arterioles have higher resistance, and confer the main drop in blood pressure along the circulatory system. Vascular pressure wave Modern physiology developed the concept of the vascular pressure wave (VPW). This wave is created by the heart during the systoleand originates in the ascending aorta. Much faster than the stream of blood itself, it is then transported through the vessel walls to the peripheral arteries. There the pressure wave can be palpated as the peripheral pulse. As the wave is reflected at the peripheral veins, it runs back in a centripetal fashion. When the reflected wave meets the next outbound pressure wave, the pressure inside the vessel rises higher than the pressure in the aorta. This concept explains why the arterial pressure inside the peripheral arteries of the legs and arms is higher than the arterial pressure in the aorta,[28][29][30] and in turn for the higher pressures seen at the ankle compared to the arm with normal ankle brachial pressure index values. Regulation The endogenous regulation of arterial pressure is not completely understood, but the following mechanisms of regulating arterial pressure have been well-characterized: â⬠¢ Baroreceptor reflex: Baroreceptors in the high pressure receptor zones detect changes in arterial pressure. These baroreceptors send signals ultimately to the medulla of the brain stem, specifically to the Rostral ventrolateral medulla (RVLM). The medulla, by way of the autonomic nervous system, adjusts the mean arterial pressure by altering both the force and speed of the hearts contractions, as well as the total peripheral resistance. The most important arterial baroreceptors are located in the left and rightcarotid sinuses and in the aortic arch.[31] â⬠¢ Renin-angiotensin system (RAS): This system is generally known for its long-term adjustment of arterial pressure. This system allows the kidney to compensate for loss in blood volume or drops in arterial pressure by activating an endogenous vasoconstrictorknown as angiotensin II. â⬠¢ Aldosterone release: This steroid hormone is released from the adrenal cortex in response to angiotensin II or high serum potassiumlevels. Aldosterone stimulates sodium retention and potassium excretion by the kidneys. Since sodium is the main ion that determines the amount of fluid in the blood vessels by osmosis, aldosterone will increase fluid retention, and indirectly, arterial pressure. â⬠¢ Baroreceptors in low pressure receptor zones (mainly in the venae cavae and the pulmonary veins, and in the atria) result in feedback by regulating the secretion of antidiuretic hormone (ADH/Vasopressin), renin and aldosterone. The resultant increase inblood volume results an increased cardiac output by the Frankââ¬âStarling law of the heart, in turn increasing arterial blood pressure. These different mechanisms are not necessarily independent of each other, as indicated by the link between the RAS and aldosterone release. Currently, the RAS is targeted pharmacologically by ACE inhibitors and angiotensin II receptor antagonists. The aldosterone system is directly targeted by spironolactone, an aldosterone antagonist. The fluid retention may be targeted by diuretics; the antihypertensive effect of diuretics is due to its effect on blood volume. Generally, the baroreceptor reflex is not targeted in hypertensionbecause if blocked, individuals may suffer from orthostatic hypotension and fainting. Measurement A medical student checking blood pressure using a sphygmomanometer and stethoscope. Arterial pressure is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure.[32] Blood pressure values are generally reported in millimetres of mercury (mmHg), though aneroid and electronic devices do not use mercury. For each heartbeat, blood pressure varies between systolic and diastolic pressures. Systolic pressure is peak pressure in the arteries, which occurs near the end of the cardiac cyclewhen the ventricles are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. An example of normal measured values for a resting, healthy adult human is 120 mmHgsystolic and 80 mmHg diastolic (written as 120/80 mmHg, and spoken [in the US and UK] as one-twenty over eighty). Systolic and diastolic arterial blood pressures are not static but undergo natural variations from one heartbeat to another and throughout the day (in a circadian rhythm). They also change in response to stress, nutritional factors, drugs, disease, exercise, and momentarily from standing up. Sometimes the variations are large. Hypertension refers to arterial pressure being abnormally high, as opposed to hypotension, when it is abnormally low. Along with body temperature, respiratory rate, and pulse rate, blood pressure is one of the four main vital signs routinely monitored by medical professionals and healthcare providers.[33] Measuring pressure invasively, by penetrating the arterial wall to take the measurement, is much less common and usually restricted to a hospital setting. Noninvasive The noninvasive auscultatory and oscillometric measurements are simpler and quicker than invasive measurements, require less expertise, have virtually no complications, are less unpleasant and less painful for the patient. However, noninvasive methods may yield somewhat lower accuracy and small systematic differences in numerical results. Noninvasive measurement methods are more commonly used for routine examinations and monitoring. [edit]Palpation A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution.[34] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of 50 mmHg, and only a carotid pulse in patients with a systolic blood pressure of 40 mmHg.[34] A more accurate value of systolic blood pressure can be obtained with a sphygmomanometer and palpating the radial pulse.[35] The diastolic blood pressure cannot be estimated by this method.[36] The American Heart Association recommends that palpation be used to get an estimate before using the auscultatory method. Auscultatory Auscultatory method aneroid sphygmomanometer with stethoscope Mercury manometer The auscultatory method (from the Latin word for listening) uses a stethoscope and asphygmomanometer. This comprises an inflatable (Riva-Rocci) cuff placed around the upperarm at roughly the same vertical height as the heart, attached to a mercury or aneroidmanometer. The mercury manometer, considered the gold standard, measures the height of a column of mercury, giving an absolute result without need for calibration and, consequently, not subject to the errors and drift of calibration which affect other methods. The use of mercury manometers is often required in clinical trials and for the clinical measurement of hypertension in high-risk patients, such as pregnant women. A cuff of appropriate size is fitted smoothly and snugly, then inflated manually by repeatedly squeezing a rubber bulb until the artery is completely occluded. Listening with the stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff. When blood just starts to flow in the artery, the turbulent flow creates a whooshing or pounding (first Korotkoff sound). The pressure at which this sound is first heard is the systolic blood pressure. The cuff pressure is further released until no sound can be heard (fifth Korotkoff sound), at the diastolic arterial pressure. The auscultatory method is the predominant method of clinical measurement.[37] Oscillometric The oscillometric method was first demonstrated in 1876 and involves the observation of oscillations in the sphygmomanometer cuff pressure[38] which are caused by the oscillations of blood flow, i.e., the pulse.[39] The electronic version of this method is sometimes used in long-term measurements and general practice. It uses a sphygmomanometer cuff, like the auscultatory method, but with an electronic pressure sensor (transducer) to observe cuff pressure oscillations, electronics to automatically interpret them, and automatic inflation and deflation of the cuff. The pressure sensor should be calibrated periodically to maintain accuracy. Oscillometric measurement requires less skill than the auscultatory technique and may be suitable for use by untrained staff and for automated patient home monitoring. The cuff is inflated to a pressure initially in excess of the systolic arterial pressure and then reduced to below diastolic pressure over a period of about 30 seconds. When blood flow is nil (cuff pressure exceeding systolic pressure) or unimpeded (cuff pressure below diastolic pressure), cuff pressure will be essentially constant. It is essential that the cuff size is correct: undersized cuffs may yield too high a pressure; oversized cuffs yield too low a pressure. When blood flow is present, but restricted, the cuff pressure, which is monitored by the pressure sensor, will vary periodically in synchrony with the cyclic expansion and contraction of the brachial artery, i.e., it will oscillate. The values of systolic and diastolic pressure are computed, not actually measured from the raw data, using an algorithm; the computed results are displayed. Oscillometric monitors may produce inaccurate readings in patients with heart and circulation problems, which include arterial sclerosis, arrhythmia, preeclampsia, pulsus alternans, and pulsus paradoxus. In practice the different methods do not give identical results; an algorithm and experimentally obtained coefficients are used to adjust the oscillometric results to give readings which match the auscultatory results as well as possible. Some equipment uses computer-aided analysis of the instantaneous arterial pressure waveform to determine the systolic, mean, and diastolic points. Since many oscillometric devices have not been validated, caution must be given as most are not suitable in clinical and acute care settings. The term NIBP, for non-invasive blood pressure, is often used to describe oscillometric monitoring equipment. Continuous noninvasive techniques (CNAP) Continuous Noninvasive Arterial Pressure (CNAP) is the method of measuring arterial blood pressure in real-time without any interruptions and without cannulating the human body. CNAP combines the advantages of the following two clinical ââ¬Å"gold standardsâ⬠: it measures blood pressure continuously in real-time like the invasive arterial catheter system and it is noninvasive like the standard upper arm sphygmomanometer. Latest developments in this field show promising results in terms of accuracy, ease of use and clinical acceptance. Non-occlusive techniques: the Pulse Wave Velocity (PWV) principle Since the 90s a novel family of techniques based on the so-called Pulse wave velocity (PWV) principle have been developed. These techniques rely on the fact that the velocity at which an arterial pressure pulse travels along the arterial tree depends, among others, on the underlying blood pressure.[40] Accordingly, after a calibration maneuver, these techniques provide indirect estimates of blood pressure by translating PWV values into blood pressure values.[41] The main advantage of these techniques is that it is possible to measure PWV values of a subject continuously (beat-by-beat), without medical supervision, and without the need of inflating brachial cuffs. PWV-based techniques are still in the research domain and are not adapted to clinical settings. White-coat hypertension For some patients, blood pressure measurements taken in a doctors office may not correctly characterize their typical blood pressure.[42] In up to 25% of patients, the office measurement is higher than their typical blood pressure. This type of error is calledwhite-coat hypertension (WCH) and can result from anxiety related to an examination by a health care professional.[43] The misdiagnosis of hypertension for these patients can result in needless and possibly harmful medication. WCH can be reduced (but not eliminated) with automated blood pressure measurements over 15 to 20 minutes in a quiet part of the office or clinic.[44] Debate continues regarding the significance of this effect.[citation needed] Some reactive patients will react to many other stimuli throughout their daily lives and require treatment. In some cases a lower blood pressure reading occurs at the doctors office.[45] Home monitoring Ambulatory blood pressure devices that take readings every half hour throughout the day and night have been used for identifying and mitigating measurement problems like white-coat hypertension. Except for sleep, home monitoring could be used for these purposes instead of ambulatory blood pressure monitoring.[46] Home monitoring may be used to improve hypertension management and to monitor the effects of lifestyle changes and medication related to blood pressure.[6] Compared to ambulatory blood pressure measurements, home monitoring has been found to be an effective and lower cost alternative,[46][47][48] but ambulatory monitoring is more accurate than both clinic and home monitoring in diagnosing hypertension. Ambulatory monitoring is recommended for most patients before the start of antihypertensive drugs.[49] Aside from the white-coat effect, blood pressure readings outside of a clinical setting are usually slightly lower in the majority of people. The studies that looked into the risks from hypertension and the benefits of lowering blood pressure in affected patients were based on readings in a clinical environment. When measuring blood pressure, an accurate reading requires that one not drink coffee, smoke cigarettes, or engage in strenuous exercise for 30 minutes before taking the reading. A full bladder may have a small effect on blood pressure readings; if the urge to urinate arises, one should do so before the reading. For 5 minutes before the reading, one should sit upright in a chair with ones feet flat on the floor and with limbs uncrossed. The blood pressure cuff should always be against bare skin, as readings taken over a shirt sleeve are less accurate. During the reading, the arm that is used should be relaxed and kept at heart level, for example by resting it on a table.[50] Since blood pressure varies throughout the day, measurements intended to monitor changes over longer time frames should be taken at the same time of day to ensure that the readings are comparable. Suitable times are: â⬠¢ immediately after awakening (before washing/dressing and taking breakfast/drink), while the body is still resting, â⬠¢ immediately after finishing work. Automatic self-contained blood pressure monitors are available at reasonable prices, some of which are capable of Korotkoffs measurement in addition to oscillometric methods, enabling irregular heartbeat patients to accurately measure their blood pressure at home. Invasive Arterial blood pressure (BP) is most accurately measured invasively through an arterial line. Invasive arterial pressure measurement with intravascular cannulae involves direct measurement of arterial pressure by placing a cannula needle in an artery (usually radial, femoral,dorsalis pedis or brachial). The cannula must be connected to a sterile, fluid-filled system, which is connected to an electronic pressure transducer. The advantage of this system is that pressure is constantly monitored beat-by-beat, and a waveform (a graph of pressure against time) can be displayed. This invasive technique is regularly employed in human and veterinary intensive care medicine, anesthesiology, and for research purposes. Cannulation for invasive vascular pressure monitoring is infrequently associated with complications such as thrombosis, infection, andbleeding. Patients with invasive arterial monitoring require very close supervision, as there is a danger of severe bleeding if the line becomes disconnected. It is generally reserved for patients where rapid variations in arterial pressure are anticipated. Invasive vascular pressure monitors are pressure monitoring systems designed to acquire pressure information for display and processing. There are a variety of invasive vascular pressure monitors for trauma, critical care, and operating room applications. These include single pressure, dual pressure, and multi-parameter (i.e. pressure / temperature). The monitors can be used for measurement and follow-up of arterial, central venous, pulmonary arterial, left atrial, right atrial, femoral arterial, umbilical venous, umbilical arterial, and intracranial pressures. Fetal blood pressure Further information: Fetal circulation#Blood pressure In pregnancy, it is the fetal heart and not the mothers heart that builds up the fetal blood pressure to drive its blood through the fetal circulation. The blood pressure in the fetal aorta is approximately 30 mmHg at 20 weeks of gestation, and increases to approximately 45 mmHg at 40 weeks of gestation.[51] The average blood pressure for full-term infants: Systolic 65ââ¬â95 mm Hg Diastolic 30ââ¬â60 mm Hg[52] Blood pressure is the measurement of force that is applied to the walls of the blood vessels as the heart pumps blood throughout the body.[53] The human circulatory system is 400,000 miles long, and the magnitude of blood pressure is not uniform in all the blood vessels in the human body. The blood pressure is determined by the diameter, flexibility and the amount of blood being pumped through the blood vessel.[53] Blood pressure is also affected by other factors including exercise, stress level, diet and sleep. The average normal blood pressure in the brachial artery, which is the next direct artery from the aorta after the subclavian artery, is 120mmHg/80mmHg. Blood pressure readings are measured in millimeters of mercury (mmHg) using sphygmomanometer. Two pressures are measured and recorded namely as systolic and diastolic pressures. Systolic pressure reading is the first reading, which represents the maximum exerted pressure on the vessels when the heart contracts, while the diastolic pressure, the second reading, represents the minimum pressure in the vessels when the heart relaxes.[54] Other major arteries have similar levels of blood pressure recordings indicating very low disparities among major arteries. The innominate artery, the average reading is 110/70mmHg, the right subclavian artery averages 120/80 and the abdominal aorta is 110/70mmHg.[55] The relatively uniform pressure in the arteries indicate that these blood vessels act as a pressure reservoir for fluids that are transported within them. Pressure drops gradually as blood flows from the major arteries, through the arterioles, the capillaries until blood is pushed up back into the heart via the venules, the veins through the vena cava with the help of the muscles. At any given pressure drop, the flow rate is determined by the resistance to the blood flow. In the arteries, with the absence of diseases, there is very little or no resistance to blood. The vessel diameter is the most principal determinant to control resistance. Compared to other smaller vessels in the body, the artery has a much bigger diameter (4mm), therefore the resistance is low.[55] In addition, flow rate (Q) is also the product of the cross-sectional area of the vessel and the average velocity (Q = AV). Flow rate is directly proportional to the pressure drop in a tube or in this case a vessel. âËâ P à ± Q. The relationship is further described by Poisseulleââ¬â¢s equation âËâ P = 8à µlQ/Ãâ¬r4.[56] As evident in the Poisseulleââ¬â¢s equation, although flow rate is proportional to the pressure drop, there are other factors of blood vessels that contribute towards the difference in pressure drop in bifurcations of blood vessels. These include viscosity, length of the vessel, and radius of the vessel. Factors that determine the flowââ¬â¢s resistance as described by Poiseuilleââ¬â¢s relationship: â⬠¢ âËâ P: pressure drop/gradient â⬠¢ à µ: viscosity â⬠¢ l: length of tube. In the case of vessels with infinitely long lengths, l is replaced with diameter of the vessel. â⬠¢ Q: flow rate of the blood in the vessel â⬠¢ r: radius of the vessel Assuming steady, laminar flow in the vessel, the blood vessels behavior is similar to that of a pipe. For instance if p1 and p2 are pressures are at the ends of the tube, the pressure drop/gradient is:[57] In the arterioles blood pressure is lower than in the major arteries. This is due to bifurcations, which cause a drop in pressure. The more bifurcations, the higher the total cross-sectional area, therefore the pressure across the surface drops. This is why the arterioles have the highest pressure-drop. The pressure drop of the arterioles is the product of flow rate and resistance: âËâ P=Q xresistance. The high resistance observed in the arterioles, which factor largely in the âËâ P is a result of a smaller radius of about 30 à µm.[58] The smaller the radius of a tube, the larger the resistance to fluid flow. Immediately following the arterioles are the capillaries. Following the logic obvserved in the arterioles, we expect the blood pressure to be lower in the capillaries compared to the arterioles. Since pressure is a function of force per unit area, (P = F/A), the larger the surface area, the lesser the pressure when an external force acts on it. Though the radii of the capillaries are very small, the network of capillaries have the largest surface area in the vascular network. They are known to have the largest surface area (485mm) in the human vascular network. The larger the total cross-sectional area, the lower the mean velocity as well as the pressure.[55] Reynoldââ¬â¢s number also affects the blood flow in capillaries. Due to its smaller radius and lowest velocity compared to other vessels, the Reynoldââ¬â¢s number at the capillaries is very low, resulting in laminar instead of turbulent flow.[59] The Reynoldââ¬â¢s number (denoted NR or Re) is a relationship that helps determine the behavior of a fluid in a tube, in this case blood in the vessel. The equation for this dimensionless relationship is written as:[56] â⬠¢ à : density of the blood â⬠¢ v: mean velocity of the blood â⬠¢ L: characteristic dimension of the vessel, in this case diameter â⬠¢ à ¼: viscosity of blood The Reynoldââ¬â¢s number is directly proportional to the velocity and diameter of the tube. Note that NR is directly proportional to the mean velocity as well as the diameter. A Reynoldââ¬â¢s number of less than 2300 is laminar fluid flow, which is characterized by constant flow motion, whereas a value of over 4000, is represented as turbulent flow. Turbulent flow is characterized as chaotic and irregular flow.[56] Disorders Disregulation disorders of blood pressure control include high blood pressure, blood pressure that is too low, and blood pressure that shows excessive or maladaptive fluctuation. High Main article: Hypertension Overview of main complications of persistent high blood pressure. Arterial hypertension can be an indicator of other problems and may have long-term adverse effects. Sometimes it can be an acute problem, for examplehypertensive emergency. All levels of arterial pressure put mechanical stress on the arterial walls. Higher pressures increase heart workload and progression of unhealthy tissue growth (atheroma) that develops within the walls of arteries. The higher the pressure, the more stress that is present and the more atheroma tend to progress and the heart muscle tends to thicken, enlarge and become weaker over time. Persistent hypertension is one of the risk factors for strokes, heart attacks,heart failure and arterial aneurysms, and is the leading cause of chronic renal failure. Even moderate elevation of arterial pressure leads to shortened life expectancy. At severely high pressures, mean arterial pressures 50% or more above average, a person can expect to live no more than a few years unless appropriately treated.[60] In the past, most attention was paid to diastolic pressure; but nowadays it is recognised that both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are also risk factors. In some cases, it appears that a decrease in excessive diastolic pressure can actually increase risk, due probably to the increased difference between systolic and diastolic pressures (see the article on pulse pressure). If systolic blood pressure is elevated (140) with a normal diastolic blood pressure (
