Alternative School Placement

Alternative School Placement The Effectiveness or Ineffectiveness of Alternative School Placement Dec 19, 2019 in Education Purpose Statement In most cases, students with behavioral disorders and other disabilities are at risk of leaving school. This happens because conventional schools are failing to meet multiple needs of students with such disabilities (Lehr, 2004). For this reason, alternative programs and schools have appeared as a way out for such students who cannot succeed in conventional schools. According to the Disabilities Education Act, the individuals with behavioral disabilities from age 3 to age 18 or 21 can receive special alternative education services within a variety of placement options (Mathur Jolivette, 2012). The range of placement options includes alternative classrooms, alternative education schools, residential school, and juvenile detention centers. The purpose of this research is to examine the effectiveness of Alternative School Placement for students with behavior problems. In the related research, it is important to determine how alternative schooling meets the needs of students with behavi oral disorders, how it offers equal access to the educational opportunities, and the most important question is what kind of alternative schooling must be served for such children (Smink Schargel, 2004). Participant Protection The research will engage some members of the teaching staff in Corleon Junior High School, which is located in the Northeastern part of Mississippi. I will approach the gatekeeper for permission to access the learning institution in order to conduct a survey on the effectiveness of alternative school placement to the student. A brief but clear introduction will be provided to the gatekeeper in order to clarify the matter and its importance. I will thereafter proceed to the administration block to seek permission from the schools principal regarding the survey. I will also provide detailed information on the research and the reason why Corleon Junior High School teaching staff is best suited for the research. The head teacher will provide us with a letter that will indicate her approval for the survey that will be conducted within the school with the help of the teaching staff. I will later proceed to the staffroom with the guidance from the deputy principal and select part of the tea ching staff that will help me to conduct the survey. Out of the entire population size of Corleon Junior High, the research will include only the employees who are willing to participate in the study. This means that the teachers will provide information on a voluntary basis. Not every teacher in the school will participate in the study; this will be due to time limitations, and reduction of extra costs that may incur if the research incorporates all members of Corleons teaching staff. The sample size of the entire teaching population is expected to give their full cooperation toward this research so that the research can generate the most accurate findings. Having familiarized myself with the teaching staff and the sample for the research, I leave Corleon Junior High School with permission from the Head teacher, the sample, and the gatekeeper who is important for security reasons. The names of the sample will be concealed during and after the study for confidentiality reasons (Smin k Schargel, 2004). Participants: Demographics of the School The High School in Northeastern Mississippi, which will provide the data for the study on effectiveness or ineffectiveness of alternative school placement, is relatively large with our streams on every grade. The school is centrally placed in terms of transport network and amenities, and this makes it suitable for most parents and guardians to bring their children here. Various socio-economic factors have contributed to different demographic groups of students in this school and these external factors have directly or indirectly affected the school. Numerous students come from middle class homes while a certain proportion hail from rich families. The rest of the student-population comprises of the lower class with parents who are engaged in small businesses. The school has a diverse racial constitution with about 38% of the students being of African-American race. The rest of the population belongs to the white race and other races like Asians. The students have learnt to co-exist an d make the school environment conducive through embracing all racial differences. Reports from the administrations, however, reveal that there are few cases arising from racial backgrounds though the administration has been working hard to eliminate any racial segregation within the student body. Order now Live Chat The presence of different manufacturing companies in the area has contributed to the high number of students in this school with their parents/guardians opting to take their children to school here due to convenience since after school hours they can all travel home together. Indiscipline is a vice that is strongly fought against in this institution though there have been several cases concerning discipline in the past. The students who are found guilty are punished accordingly and in some extreme cases, they are asked to bring their parents. Few students have been suspended or permanently sent away from the school. Some students with disciplinary disorders have been referred to other schools that can accommodate their disorders and shape them while providing them with the same education. Alternative programs and schools have appeared as a way out for such students who have been unable to succeed in a similar school to this one. Instruments There will be different instruments and materials that will be used in this research, and they include writing material, which will have the questionnaire forms that will be filled by our sample teachers during the study. Pens and other important stationery like rulers and marker pens will be mandatory in this study. There will be use of computers and the internet will be useful in gathering online data about the effectiveness of the school placement programs. Design The sampling of data will be conducted to select 30% of the schools teaching staff. The individuals who will constitute the primary source of data will fill in the questionnaires and give verbal information that will be recorded for the final tabulation in percentages and charts. The internet, is another source of data that will be classified in the secondary source, will be very useful in this process and through the help of the internet, I will be able to search for more details on the topic of study online. This will help in the discovery of more facts and details on alternative school placement and its impacts to students. I will, as a result, gather all information needed in the research regarding its negative and positive impacts. The mode in which I will carry out the research will be aimed at incorporating all the views and information of the sample population from the teachers in the school and incorporate data from secondary sources. It is a fact that most members of the te aching staff get into contact with children with such disorders in their day-to-day teaching responsibilities. The teachers have first-hand experience with the students with disorders that call for alternative placement and they are, therefore, best suited for this role of providing data. Bearing in mind the pressure on cost and time to be taken in the research, the sample will only include data from the teachers who will offer to give information on the same and whose percentage will be estimated to be 30% of the teaching staff. Procedure The actual execution of the survey will kick off early in the morning on the conclusive study with the research assistants preparing the materials and equipment to be used. They will ensure that the sample is present and that they are composed to provide adequate and accurate information on the topic of study. The verbal interview will be conducted on the area of choice of the teacher and this will ensure that they are at ease to answer all the questions that arise. The questionnaires will be distributed evenly to all the teachers providing the study with information. The actual interviews are set to kick off at exactly nine oclock and it will begin by verbal investigation with the help of the research assistants. After all the teachers have provided their views and observations on alternative school placement, they will be provided with a questionnaire that will touch on the statistics pertaining to alternative school placement. The teachers will give a probability of the number of students enrolled in alternative placement institutions from the pre-kindergarten level through to the secondary education level. The questionnaire will also require the teachers to give their ratio of girls to boys who are enrolled in the special schools. Being that they spend most of the time with the students than any other person, the teachers have a provision to give their general views and suggestions concerning this matter. The team will ensure that the teachers exhaust themselves in providing information by providing them to add any point that they deem necessary for the research. After a thorough interaction with the sample, I will contact the internet to gather information on the school and how it relates to alternative placement program to some of the students who have been noted to possess similar disorders. The information gathered on the effectiveness or ineffectiveness of the alternative schools for students with special cases and behavioral disorders. The data collected from the internet and the sample will be represented in different forms to enable analysis of the results. Once the sample population has provided the data that will be on a non-probability basis, the data will then be processed and it will be described by tabulation percentage and graphs, too. The tabulation percentages and the graphs will help in reading and interpreting the data collected. In order to select the ideal population group to be used in the study, it will be chosen on the basis of the teachers experience and this will help in eliminating inaccurate data if a different method is to be used. This method of selection will be appropriate in providing total freedom in achieving relevant and conclusive data. Data Analysis From the survey conducted in the high school in Mississippi, the findings indicate that the number of cases of behavioral disorders and special cases is steadily rising as compared to five years back. The number of black special cases enrolled in the special institutions is very high as compared to white students and other races. The number of male students placed under alternative school programs is slightly higher than that of female students. The survey, however, discovered that the rate of such behavioral disorders is almost nil at the kindergarten stage, and these characters emerge as they begin their first grade. This pattern can be blamed on the fact that the children in their kindergarten years are still developing both psychologically and physically and any disorders or special conditions cannot be detected at this early stage. The 75% enrollment for black students into the alternative placement schools raises questions on the upbringing of the African-American students thou gh the research reveals that these students do not get enough exposure to physical and mental challenges while they are toddlers. Parents and guardians, however, are suspected to be lenient on their emphasis on discipline; thus, there are a high number of disorderly black students. From the deductions made from the research, the alternative school placement is a good remedy to students with behavioral disorders and special conditions. Amendments should, however, be made to these institutions to introduce more counseling and physiological lessons to ensure that the students attain the right moral and physical foundation for their future lives.

The insecurity of finding employment is ever looming. There are jobs that can be had rather quickly; i.e., low wage jobs like fast food or retail. It is impossible to support a family on a minimum wage. Converting middle wage jobs to foreign countries leaves a smaller job pool workers must fight to get into.

The topic my partner and I have based the National History Day Project on is the Mayan Calender system compared to the Hopi Indian Tribe system. The reason I liked this topic is because it is currently 2012 and so the the world ending is a huge controversy in society. I am very interested in the subject and wished to do deeper research on the predictions by not only the Ancient Civilization of the Mayans. We will write a custom essay sample on National History Day Process Paper or any similar topic only for you Order Now I have recently discovered the Maya people are not the only people with these beliefs and so I have grown more fascinated. The idea of basing our project on this topic was actually the first thing to cross my mind when we were informed of the project, so we decided it fit with everything this year. The research for this particular topic is very difficult because of the fact that the Mayans are such an ancient civilization so have very few primary sources. This is the main reason for including the more recent civilization of the Hopi Indian Tribe. I conducted my part of the research using the ABC Clio Database and other websites in which I was recommended. It is definitely not easy to conduct this research which requires a lot of patience, smart searching and reliability. We managed to find perfect information to allow us to shine the theme across the topic. The presentation category we have chosen to use is the exhibit. The reason I wanted to use this category is because my partner and I do not work best with technology and are able to better portray information in a more old-fashioned matter. I believe this is the most efficient way to get our research across. We have felt very confident with our project from the beginning. We are using a mid-sized poster board. Our creativeness works well with our topic and our research is sweet, short and to the point. Our project relates to the NHD theme of Revolution, Reform and Reaction because the ideas of the Hopi Indians coincides with those of the Mayans. This part relates to the Revolution portion of the theme. The topic relates to the reform section because it has been edited and is used today. The reaction part is how the people have reacted to the end of this system and the predictions made according to their astrological beliefs.

The Country wife

Written by William Wycherley, The Country Wife qualifies as a captivating informative piece of chef-d’oeuvre that tables the characteristics of the contemporary society that range from intimacy and hypocrisy amongst others. Advertising We will write a custom essay sample on The Country wife specifically for you for only $16.05 $11/page Learn More Harry Horner believes that his impotence would permit him to gain access to high-class women and have liaisons with them with the whole deal remaining secreted. He convinces ladies for instance in scene four where he manages to liaise with lady Fidget though â€Å"Mistress Squeamish enters too late and is disappointed to have missed her opportunity† (Wycherley 50). He argues that the liaisons with women would help them retain their honor before the public due to his condition. As Wycherley observes, â€Å"Inferences from Horner’s impotence rumors make Sir Jasper Fidget to make arrangements for Horner to become his wife’s chaperone and also her companion, later to turn out a secrete affair† (57). Upon the departure of Sir Fidget and his wife, two of Horner’s friends: Mr. Dorliant and Frank Harcourt enters, chat with him about friendship, wine and women. Amid the debate, Mr. Sparkish arrives who on boring the three men by his pretentious wit is exited by force. Jack Pinchwife portray his contempt for women when he ignorantly leaves Horner and his friends as Horner mentions that he had seen his wife, Margery at theatre. Margery complains to her sister in law about the Pinchwife’s jealousy, which render her forced to remain indoors. â€Å"On inquiring about the reason, Pinchwife laments that a licentious man had sighted her at the theatre and fallen in love with her† (Wycherley 60). Since Margery has developed interest on actors at the theatre, she gets delighted on hearing this. Later in scene three, Horner managers to hit on her, lea ve with her and later to return to her husband loaded with gifts from Horner: something that in scene five saw her visit Horner’s lodge. In scene four, consequently Pinchwife locks up her in a different room. Despite the fact that, Sparkish was to marry Alethea, his friend Harcourt in a witty way makes advances to her before his friends very eyes something that in scene three ,make Harcourt declare that he fell in love with her at first glance. In the end, Margery turns out to be the villain.Advertising Looking for essay on british literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More The villain Margery Inexperience and innocence’s puts Margery far from being the heroin of play. She poses a question, â€Å"jealous? What’s that?† (Wycherley 61), which proves unfamiliarity with characteristics of men and women dominating the country when it comes to issues of emotion and affection. Unlike other women, she nat urally does not subscribe to deceit implying why she did compose a love letter to Horner. Horner shed light that Margery’s love letter was â€Å"the first love-letter that ever was without flames, darts, fates, and destinies, lying and dissembling in it† (Wycherley 82). She seems to judge a book by its cover, and objects the belief that people who claim to be in love with her are up for missions to ruin her. She believes in guarding whatever that she holds and loves passionately. She tells Pinchwife â€Å"You are mine own dear bud, and I know you; I hate a stranger† (Wycherley 91). This indicates her strongly ingrained subscriptions to customs that dictates that wives should always remain kind to their husbands despite treating them with lots of dismay. Her kindliness and the ideologies that she subscribed to, resulted to her being caught up by her husband when she decided to adopt the lifestyle of her female counterparts in the country. Despite the intimacy characterizing other women of the country, who only subscribed to infidelity and adultery for sexual services only, Margery is still carrying the load of affection and idealism. These explain why in scene four Margery thought of dropping Pinchwife and take Horner for her husband. Margery stands out as a sympathetic character to the extent that sees her rejection by the society in the country, which does not accommodate people with such magnitudes of ingeniousness, simplicity and honesty that she poses. In conclusion, The Country Wife presents a society that is full of intimacy, infidelity, hypocrisy, loveless sexual encounters arrangements and one sex solidarism with intents of deceit.

Amplifier Essay Example

Amplifier Essay Example Amplifier Essay Amplifier Essay Class A amplifiers amplify over the whole of the input cycle such that the output signal is an exact scaled-up replica of the input with no clipping. Class A amplifiers are the usual means of implementing small-signal amplifiers. They are not very efficient - a theoretical maximum of 50% is obtainable, but for small signals, this waste of power is still extremely small, and can be easily tolerated. Only when we need to create output powers with appreciable levels of voltage and current does Class A become problematic. In a Class A circuit, the amplifying element is biased such that the device is always conducting to some extent, and is operated over the most linear portion of its characteristic curve (known as its transfer characteristic or transconductance curve). Because the device is always conducting, even if there is no input at all, power is wasted. This is the reason for its inefficiency If high output powers are needed from a Class A circuit, the power wastage will become significant. For every watt delivered to the load, the amplifier itself will, at best, waste another watt. For large powers this will call for a large power supply and large heat sink to carry away the waste heat. Class A designs have largely been superseded for audio power amplifiers, though some audiophiles believe that Class A gives the best sound quality, due to it being operated in as linear a manner as possible. In addition, some aficionados prefer thermionic valve (or tube) designs over transistors, for a number of reasons: Tubes are more commonly used in class A designs, which have an asymmetrical transfer function. This means that distortion of a sine wave creates both odd- and even-numbered harmonics. They claim that this sounds more musical than the purely odd harmonics produced by a symmetrical push-pull amplifier. Though good amplifier design can avoid inducing any harmonic patterns in a sound reproduction system, the differences in harmonic content are essential to the sound of intentional electric guitar distortion. Another is that valves use many more electrons at once than a transistor, and so statistical effects lead to a smoother approximation of the true waveform - see shot noise for more on this. Field-effect transistors have similar characteristics to valves, so these are found more often in high quality amplifiers than bipolar transistors. Historically, valve amplifiers often used a Class A power amplifier simply because valves are large and expensive; Many Class A design uses only a single device. Transistors are much cheaper,

Definition of Boycott

Definition of Boycott The word boycott entered the English language because of a dispute between a man named Boycott and the Irish Land League in 1880. Where Boycott Got Its Name Captain Charles Boycott was a British Army veteran who worked as a landlords agent, a man whose job was to collect rents from tenant farmers on an estate in northwest Ireland. At the time, landlords, many of whom were British, were exploiting Irish tenant farmers. As part of a protest, the farmers on the estate where Boycott worked demanded a reduction in their rents. Boycott refused their demands and evicted some tenants. The Irish Land League advocated that people in the area not attack Boycott, but rather use a new tactic: refuse to do business with him at all. This new form of protest was effective, as Boycott wasnt able to get workers to harvest crops. By the end of 1880 newspapers in Britain began using the word. A front-page article in the New York Times on December 6, 1880, referred to the affair of Capt. Boycott and used the term boycottism to describe tactics of the Irish Land League. Research in American newspapers indicates that the word crossed the ocean during the 1880s. In the late 1880s boycotts in America were being referred to in the pages of the New York Times. The word was generally used to denote labor actions against businesses. For example, the Pullman Strike of 1894 became a national crisis when a boycott of railroads brought the nations rail system to a halt. Captain Boycott died in 1897, and an article in the New York Times on June 22, 1897, noted how his name had become a common word: Capt. Boycott became famous through the application of his name to the relentless social and business ostracism first practiced by the Irish peasantry against the detested representatives of landlordism in Ireland. Although a descendant of an old Essex County family in England, Capt. Boycott was an Irishman by birth. He made his appearance in County Mayo in 1863 and according to James Redpath, he had not lived there five years before he won the reputation of being the worst land agent in that section of the country. The 1897 newspaper article also provided an account of the tactic that would take his name. It described how Charles Stewart Parnell  proposed  a plan to ostracize land agents during a speech in Ennis, Ireland, in 1880. And it described in detail how the tactic was utilized against Captain Boycott: When the Captain sent for the tenantry on the estates for which he was agent to cut the oats, the whole neighborhood combined in a refusal to work for him. Boycotts herdsmen and drivers were sought out and persuaded to strike, his female servants were induced to leave him, and his wife and children were obliged to do all of the house and farm work themselves. Meanwhile his oats and corn remained standing, and his stock would have been unfed had he not exerted himself night and day to attend to their wants. Next the village butcher and grocer declined to sell provisions to Capt. Boycott or his family, and when he sent to neighboring towns for supplies he found it absolutely impossible to get anything. There was no fuel in the house, and nobody would cut turf or carry coal for the Captains family. He had to tear up floors for firewood. Boycotting Today The tactic of boycotting was adapted to other social movements in the 20th century. One of the most significant protest movements in American history, the Montgomery Bus Boycott, demonstrated the power of the tactic. To protest segregation on city buses, African American residents of Montgomery, Alabama, refused to patronize the buses for more than 300 days from late 1955 to late 1956. The bus boycott inspired the Civil Rights Movement of the 1960s and changed the course of American history. Over time the word has become quite common, and its connection to Ireland and the land agitation of the late 19th century has been generally forgotten.

How To Be Idle Essay Example | Topics and Well Written Essays - 1000 words

How To Be Idle - Essay Example Individual benefits can easily come from having an early evening drink, meditating, and rambling about aimlessly. While societal benefits may be more easily found in savoring the mid-day meal, leisurely naps, and conversing with people. Though touting the benefits of alcohol may start rumors of alcoholism, it can have benefits physically and figuratively. The evening drink marks the end of the work day. All the frustration, endless reports, and endless traffic now become a distant memory against the backdrop of cheerful conversation and the promise of a relaxing evening. Hodgkinson likens this to a transformation into Buddhism, where thoughts of past or future cease and only the present remains. He paints the picture rather well that it is at this time that people become their â€Å"own master's once more† broken free from the chains of â€Å"wage slavery† (113). It is true that there are those who would take this evening drink and continue into a stupor, but that would be missing the point. The point is to become reinvigorated, not comatose. Achieving a balance of working hard while still pursuing other interests in life including daydreaming is important for people if the goal is quality of life. Hodgkinson suggests using general moments of idleness to meditate, or simply day dream such as waiting for a friend, or bus or while being stuck in a traffic jam (228) . Meditation is world renown as being a soothing exercise to de-stress, and clear one's mind. This helps people to realign themselves with what is really important in life and releases them from that feeling of bondage that the modern trappings of consumerism and debt can have. Some promise that alternative lifestyles will help to free oneself from the feeling of bondage, but consequently they only offer an â€Å"alternative set of rules† that have their own complications (Hodgkinson 228). Of course, it is difficult to ignore the honking of cars and the endless dribble of half hear d conversations, but it is achievable and certainly admirable in the attempt. Walking around aimlessly was once the sole right of the elderly, but no longer. Granted it is not a requirement to be without a destination when rambling, but it is crucial not be fixated on it. Take in the sights. Smell the roses, so to speak. Be a loafer. It is amazing what a person can find when not looking. In truth, rambling is another form of meditation. It is meant to gain appreciation and wonder for everyday scenes like a leaf falling from a tree or the way the clouds move with an oncoming storm. Henry Thoreau said that it is easy â€Å"to become a slave driver of yourself† (qtd. in Hodgkinson 228). Rambling is a way of unlocking the chains of slavery that we have placed on ourselves much like the evening drink unchains us from the bondage of the work place. There was once a time when the mid-day meal meant something in society other than just an energy boost to employees so they can keep sl ugging away at the office or factory. It was a chance to get shade from the sun, catch up with friends, and take a leisurely nap. In short, it was a real energy boost. Right now in most western countries it is simply a legal obligation on behalf of the boss. Otherwise, it seems doubtful a person would ever see it. The average Joe looks forward to lunch all morning only to barely get enough time to eat it.

Race And Ethnicity Essay Example | Topics and Well Written Essays - 2250 words

Race And Ethnicity - Essay Example The Act and its subsequent amendments offer protection regardless of whether an individual propagates racism deliberately or not in the society (Tonry, 1998: 49). However, racial discrimination persists in British society a situation that has resulted to serious social crisis in the country. Access to medical services is one sector where racism and racial discrimination is prevalent in Britain. Findings from research study conducted by Smedley (2001) established that people from minority groups in United Kingdom experience worse health than those from the majority group. (Smedley, 2001: 25). Though there are various opinions regarding these findings, noted that the minority groups experienced many socioeconomic challenges that undermined their access to medical care. In health sector, Smedley, (2001) argues that perceptions attributed to the biological and cultural differences of the minority groups undermine their accessibility to health in Britain (Smedley, 2001: 37). These percept ions are usually used to justify unfair medical attention in health care institutions across the country. The study established that these negative perceptions prevented minority groups from interacting with medical staff in the country. The minorities face other additional social-economic challenges such as poor economic status and when these unjustified perceptions are included, access to good medical care becomes a difficult challenge. According to Benzeval et al (1992), racial discrimination in the United Kingdom affects health of the minorities in various ways. They include poor sanitation and living conditions, which arises from inequitable distribution of resources, poor treatment due to lack of resources... This paper stresses that health care system in the United Kingdom lacks important aspects, which perpetuates racial discrimination in the sector. These include lack of representative medical staff from the minority groups, insufficient policies and regulations to address patients from minority groups, in addition to very few users from the minority ethnic groups. Other aspects in the health sector include lack of medical staff qualified to work in ethnically diverse environment and poor relationship with non-governmental organisations that provides care to the minorities. Another major area of racial discrimination in Britain is the criminal justice system. In United States, African Americans a minority race continue to suffer from high levels of criminal injustice especially in capital offenses and imprisonments. This report makes a conclusion that the British government has made commendable efforts in ensuring that racial discrimination is eliminated, incidents of racial discrimination persists in the society and in institutions. This trend points to the widely construed notion that regards particular social group of people to certain characteristics. Regrettably, the ascribed notions have been used to draw and direct inhuman treatment to that particular group. In this regard, it is important for all British citizens to realize that respect for human dignity especially to the minority groups is the ideal measure of the country’s social economic development. This can be attained by ensuring equal access to justice, health, employment, education and in the political structure of the country.

Movement in an Idealized Dam-break Configuration

Movement in an Idealized Dam-break Configuration For doing the research of the fluid dynamics with the open channel flow, to derive and understanding different waves equations in partial differential approximation with conservation form such as the explicit centered convection approximation and the explicit upwind convection approximation in different condition. Trying to substitutive the values into the equations to derive the appropriate method base on the finite- volume method in the fluid dynamics and using the software to calculate the flux and the stability which will depend on the direction of the wave and must be under the distance travel must not exceed the step way condition. The aim is staring to go through the details of the equations, get the brand new Flux functions which called lax Wendorff burgers equation scheme and Dam break scheme, based on those approximation to estimate the wave direction, wave speed, height, density and momentum in the certain and instant time for the water wave and at different conditions property and combinations. Putting the values to get the approximate results with those two methods and compare with each other. Plot the appropriate graphs. Abstract The purpose of this study is to model the flow movement in an idealized dam-break configuration. One-dimensional motion of a shallow flow over a rigid inclined bed is considered. The resulting shallow water equations are solved by finite volumes using the Lax-Wendroff schemes. At first, the one-dimensional model is considered in the development process. With conservative finite volume method, splitting is applied to manage the combination of hyperbolic term and source term of the shallow water equation and then to promote 1D. The simulations are validated by the comparison with flume experiments. Unsteady dam-break flow movement is found to be reasonably well captured by the model. The proposed concept could be further developed to the numerical calculation of non-Newtonian fluid or multilayers fluid flow. All the calculations, data and graphs represent are all through MATLAB programming with an individual code and all the units and symbols were labeled in the code. A. Units and constant for the approximations Equations Theory Partial Differentials Partial differential equations are complicated method to solve as they contain more than one variable and instead are used to Describe problems involving the parameters in use which can be solved using the variation of schemes. They describe the certain rate of change of variables which are related to each other, in this project, the first convection are the wave equation in conservation form which are to approximate the velocity of the flow in different directions and the flux approximation with changing time. Two different methods are considered which are the explicit upwind convection approximation and explicit centered convection approximation respectively. When dt = 0 and dx = 0, Discretization Schemes Explicit centered convection approximation and explicit upwind convection approximation, these methods include finite volume method which approximating the variables around discrete nodes with dissected into too many small elements that are approximated. Finite-Difference Approximation Finite-difference approximations are one of the most derivative methods for solving differential equations. The system can approximate the solution with the necessary boundary and initial conditions imposed, providing an accurate solution for the previous unfathomable equation. They are of particular use in aerodynamics as their time and space dependent nature lends itself to computing shock wave propagation or other energy transfer flows. Their approach uses discretization to approximate the differential, by applying a finite grid, of points at which the variables are estimated, with the process continuing as the local points govern their approximation values from the neighboring nodes. Iterative approximation in this manner produces an obvious error, known as the discretization or truncation error, diverging from the true value. The key to the principle is, like anything, minimizing this error in the system. Monitoring this error then is something of paramount importance and through the implementation of the Taylor Series. In addition, there are three critical properties that any approximation of a partial differential should maintain, which are consistency, stability and convergence. Forward-Time, Backward-Space Scheme The form of approximation method is a backward, explicit, hyperbolic system which means that at the next set of results are only calculated from the nodes immediately behind them geometrically, in relation to their pervious counterparts, for examples, When dt = 0 and dx = 0, This also gives the system an inherent advantage as this encourages convergence, through the fact that the approximation method has a domain of dependence which are include the initial data, shared by the partial differential at t = 0, only apply on the first set of data. Also, further information gathered from the equation itself shows is a first order method and most suitable to simple differential approximations. Lax Scheme This kind of approximations are most likely the previous is explicit hyperbolic in nature, however, it is a scheme which to demonstrated that all the velocity of the water flow terms are either side of and is first order accurate for u, and also approximate the accuracy for x. When dt = 0 and dx = 0, Moreover, the stability of the method has to be considered as the Courant-Friedrichs-Lewy (CFL) condition is a necessary condition for convergence while solving certain partial differential equations usually hyperbolic numerically by the method of finite differences. It arises in the numerical analysis of explicit time integration schemes, when these are used for the numerical solution. As a consequence, the time step must be less than a certain time in many explicit time-marching computer simulations, otherwise the simulation will produce incorrect results. Lax-Wendroff Scheme This scheme is a common numerical method for the solution of hyperbolic partial differential equations like the previous schemes which are based on the finite differences to accurate for both space and time apparently. There are two different cases are going to consider and approximate which are the 1st for the linear case, while , where a is a constant which to define the direction of the flow and u is the wave speed, when, the flow is to the right, and to the left when a is negative. As two different approximations have considered, for the centered method For the upwind method Or Or And for the Lax-Wendroff in first-order Predictor, Corrector, For the 2nd case, Centered method For the upwind method Or Or And for the Lax-Wendroff in first-order Predictor, Corrector, Calculate for the half grid points and time steps approximation as different predictors first and then recalculate the scheme by the value of half grid points and time steps into same Corrector which putting a two steps approximation rather than a single step to make it more accurate. This is a feature unique for the Lax-Wendroff method. Also, the stability of CFL condition is the same as the previous scheme. Taylor Series The Taylor series is a form of evaluating and representing partial differentials, as an infinite sum of its terms at a single point, in form of series expansion. The use of the series has many applications in engineering, with its main being the approximation of functions through the expansion to the necessary number of terms. Through collating the appropriate number of terms and then truncating the series a valid approximation of the function can be made. The act of truncating the series generates an error, although as the expansion continues the effect of each term dwindles, a characteristic that allows the truncation after a certain term number. The truncation error can also be computed and gives an indication as to the validity and performance of the initial approximation made using the series expansion. B. Dam break schme The simplest situations will first be considered, of mass, momentum and energy conservation laws in primitive form, so stripped of all energy-diffusing terms, such as bed slope , resistance, change of section. Governing Equations The mass entering t element in time dt is While the amount leaving is For the mass For the momentum For the simplest case, X1 Figures and Tables Figure 1 Figure 1 shows the relationship of the velocity against the postion of the flow in linear first-order which (f = a*u) , where a is 1, Lax-Wendroff is used for approximation, and it shows a steady flow with a certain time and positions with the input data, there are 50 nodes in total and the grid spacing are 400 as the detla time was 0.0015s, so the grid spacing should have to take a really large value to maintain the CFL. Figure 2 Figure 2 shows the relationship of the velocity against the postion of the flow in non-linear first-order which (f = u2/2), Lax-Wendroff is used for approximation, and it shows a steady flow with a certain time and positions with the input data, there are 50 nodes in total and the grid spacing are 30 as the detla time was 0.0015s, the grid spacing take a really smaller value to maintain the CFL. Figure 3 Figure 4 Figure 3 Figure 4 shows the relationship between the height against the spacing and the momentum against the spacing respectively, dam break scheme is used with base on a Lax-Wendroff approximation and for Figure 3, the running time is 10 seconds which is shorter then Figure 4 and the depth of the dam wall sets as 0.2m and break at 30m while Figure 4 sets as 0.5m depth and break at 50m. As the results show, the longer running time it takes, the stability and convergence of the approximation comes out. Also, both of the results withdraw the boundary which take an error while plot graph. So, a function for boundary condition has to be considered as well. References Guymon, Gary L.

Children With Sickle Cell Disease Health And Social Care Essay

Transcranial Doppler scanning ( TCD ) is a critical technique which can place kids with reaping hook cell disease at high hazard for shot ( Deane et al. , 2007 ) .This non-invasive imagination technique uses an ultrasound investigation, that produces high frequence sound waves to mensurate intellectual blood flow. In this survey, cubic decimeter will be looking at the undermentioned everyday hematologic and biochemical research lab trials, hemoglobin, reticulocytes, white count, lactate dehydrogenase, aspartate aminotransferase and creatinine in 250 reaping hook cell disease ( SCD ) affected kids with in the age group of 3-16years who attend the Brent Sickle and Thalassaemia Clinic at Central Middlesex Hospital in May 2010 to May 2011. My purpose is to utilize the above listed research lab trials to place all kids who are at hazard of enduring from the complications of SCD like vaso-occlusive hurting crisis, acute chest syndrome, infections, stroke to multi organ failure. TCD is perf ormed one time a twelvemonth at one-year reappraisal assignments on all kids with reaping hook cell disease to find if they are at hazard of developing any SCD complications. During this survey any kid identified to hold unnatural hematologic and biochemical research lab trials listed supra will hold a TCD regardless of whenever it was done. If the TCD identifies that any kid with those unnatural hematologic and biochemical parametric quantities is at a high hazard of developing complications of SCD particularly stroke, so the current National Health Service ( NHS ) intervention program for kids with SCD must be changed to supply an even more robust intervention plan.The significance of this survey hence is to better hereafter pattern and attention for kids with SCD. This will intend that any SCD affected kid with those unnatural hematologic and biochemical parametric quantities will be referred for TCD regardless of whether they have had their annual scan in a pursuit to better the ir wellness and wellness attention direction. Prevention is better than remedy.2. IntroductionHemoglobinopathies are a broad group of diseases impacting the production and or the maps of hemoglobin. ( Kirkham F.J, 2007 ) . They are one of the most common familial upsets worldwide and can be really terrible, if non fatal. They are classed into two groups: Haemoglobin discrepancies which arise from an change in the hematohiston concatenation, for illustration, Sickle hemoglobin ( Hb S ) Thalassaemias which arise from reduced production of the normal hematohiston concatenation. ( Kirkham F.J, 2007 ) SCD is one of the most common familial upsets impacting the hemoglobin molecule of ruddy blood cells ( Kirkham F.J, 2007 ) . SCD is an autosomal recessionary disease, intending a individual needs two faulty cistrons to hold the disease ( Kirkham F.J, 2007 ) . There are several reaping hooks cell diseases: homozygous reaping hook cell anemia or disease ( HbSS ) and heterozygote conditions including Hb SC and Hb S? thalassemia ( Kirkham F.J, 2007 ) . HbSS is responsible for the most terrible complications seen in reaping hook cell disease ( Kirkham F.J, 2007 ) . The prevalence of SCD is highest among people of African, Afro-Caribbean, Arab and Mediterranean lineage ( Kirkham F.J, 2007 ) It is widespread in the United States, impacting over 70,000 Afro- Americans and impacting about 12,500 people in the UK ( Howard et Al ; Kirkham et al. , 2007 ) . Sickle cell is progressively going common in the UK as a effect of migration ( Howard et al.,2007 ) . The life anticipation in SCD is between 42 and 53 old ages for work forces and 48 and 58 old ages for adult females. This low life anticipation is likely to increase as the wellness service have put in topographic point national showing programmes, instruction for parents and wellness professionals and better directions attention. Complications SCD is a multi-organ upset with a assortment of complications. The most common complications include, vaso-occlusive hurting crisis, acute chest syndrome, infections, shot, priapism, leg ulcers, cholecystitis, acute splenic or hepatic segregation to multi organ failure. ( Gladwin et al, 2008 ) . Vaso-occlusine hurting crises is due to sickle cells blockading vass in the microcirculation taking to ischemic harm in the castanetss, the lung, the kidneys and in the tegument ( leg ulcers ) , ( Gladwin et al, 2008 ) . Stroke is an of import complication as it is a major cause of mortality and morbidity in SCD kids. ( NHS Standard and Guidance, March 2009 ) . It has been reported as a taking cause of decease in both kids and grownups. Infarctive shot is seen chiefly in kids whereas hemorrhagic shot is normally seen in the 20-29 age groups, ( Ohene-frempong et Al, 1998 ) . The grounds for this age division are non good understood. ( Kirkham F.J, 2007 ) . By the age of 10, about 6 % of SCD kids are affected by ischemic shot ( .Kirkham F.J, 2007 ) . It is caused by the progressive narrowing of the center, distal and anterior carotid arterias providing blood to the encephalon consequences in shot ( Deane et al, 2007 ) . However, grounds for this progressive narrowing are yet to be established ( Deane et al, 2007 ) , but recent surveies suggest an association between high degrees of plasma free hemoglobin ( PTH ) from hemolysis, quickly devouring azotic oxide ( NO ) , which may ensue in events suppressing blood flow. ( Nelson et al, 2006 ) . Even though it is a really serious complication in SCD kids, it can be preventable. ( Quinn et al 2004 ) , if these kids are identified. Transcranial Doppler scanning ( TCD ) has been shown to place patients at high hazard of shot ( Deane et al, 2007 ) . TCD is an ultrasound that measures blood flow speed in the intracerebral vass. ( Bulas et al, 2000 ) . It is non invasive, reasonably expensive and a painless process that is good tolerated in kids. ( Bulas et al, 2000 ) . This high hazard of shot brought approximately by The Stroke Prevention Trial in Sickle Cell Anaemia ( STOP ) survey. This survey was perfomed by a group of scientist in 1996. It showed that high blood speeds as measured by TCD in the in-between intellectual arteria ( MCA ) , the distal internal arteria ( dICA ) and the bifurcation were associated with an increased hazard of shot. . ( Bulas et al, 2000 ) . These kids with high blood flow speeds were so on a regular basis transfused to cut down the hazard of shot [ new ref Adams RJ. , 1998 ] . The STOP survey has has proven important consequences on TCD as an valuable wellness technique in forestalling shot hazard in kids. ( Adams RJ. , 1998 ) given Furthermore, an experimental survey by Fullerton et Al, 2004 on SCD kids in California showed that there was a diminution in shot after the debut of TCD with contraceptive transfusion preventative steps were taken. . ( Rees et al, 2008 ) . Many surveies have shown the benefits of mensurating high blood speeds on TCD and subsequent transfusion to cut down hemoglobin S can cut down the hazard of shot. ( ) . Based on these surveies, National counsel from the NHS Sickle and Thalassaemia testing programmes recommended the usage of TCD scans all over the state. The guidelines proposed that by 2010, 99 % of reaping hook cell Centres in England should offer one-year TCD scans to kids with SCD from age 2 to 16 old ages. The scan consequences are classed into classs depending on the clip averaged maximum average speed ( TAMMV ) of the in-between intellectual arteria or the intracranial internal carotid arterias or the bifurcation of the two arterias, ( Standard and Guidance, March 2008 ) . TAMMV values & A ; lt ; 170 cm/s are normal, 170-199cm/s are conditional and & A ; gt ; 200cm/s are important forecasters of shot. ( Standard and Guidance, March 2008 ) . However, studies in the UK have shown that many kids do non hold entree to TCD scans ( Rees et al 2008 ) . Therefore it is imperative to place kids at high hazard for shot so that effectual preventative steps are taken. In this survey, based on cardinal hematologic and biochemical modus operandi trials we aim to happen research lab parametric quantities which can be used as showing tools for shot and be used in placing those kids most likely to hold an unnatural TCD scan. If these labaoratory paramaters can place SCD kids at increased hazard for shot it may take to recommendations for future pattern to include precedence for TCD scans to be given to these kids.TreatmentIn the UK, the National Health Service ( NHS ) has developed local guidelines for the intervention and direction of SCD, including: a combination of antibiotics, hurting slayers, fluids and ruddy cell transfusion when required. ( Kirkham F.J, 2007 ) . Hydroxyurea, an unwritten anticancer drug is besides used in some SC D patients to forestall painful crises ( Frenette et al, 2007 ) . Hydroxyurea works by increasing fetal hemoglobin F ( Hb F ) degrees which prevents the polymerization of the deoxygenated HbS in ruddy cells, therefore diminishing the frequence of painful crises ( Hoffbrand et al, 2001 ) . Reports from Howard et al 2007 and Frenate et Al 2007 besides explain that Hydroxyurea improves ruddy cell hydration, diminishing the adhesion of reaping hook cells to the endothelium and act as a azotic oxide giver, doing this drug rather good to utilize. A multi-centre survey of hydroyurea ( MSH ) in 299 grownups with SCD showed important benefits of utilizing this drug as patients had less one-year painful crises ( Charache et al.,1995 ) . A follow-up survey nine old ages on showed that these patients had a better quality of life ( Steinberg et al. , 2003 ) . Despite its clinical benefits, many patients are disbelieving about it being a chemotherapeutic drug and are hence disquieted about the lo ng term side effects ( Frennete et al. , 2007 ) . Bone marrow organ transplant can bring around SCD. About 175 HLA matched sibling grafts have been reported with greater than 80 % disease free patients holding a quality life ( Howard et al. , 2007 ) , nevertheless, troubles lie in happening a blood-donor lucifer and there is a hazard of decease associated with this procedure due to high doses of chemotherapy and radiation ( Frenette et al, 2007 ) . A possible remedy for SCD is cistron therapy, where infixing a normal cistron will convey about production a normal hemoglobin or shift of the faulty cistron. This is presently being investigated in research surveies as there are frights over the safety of genomic interpolation ( Sadelain et al, 2006 ) . Present surveies have shown that prenatal and neonatal showing for hemoglobinopathies in England has led to early sensing of affected kids, therefore, cut downing the post-natal and childhood morbidity and mortality ( Old J M 2007 ) .3. HistoryHaemoglobin ( Hb ) is an Fe incorporating protein, which carries O from the lungs to the organic structure ‘s cells and tissues ( Hoffbrand et al, 2001 ) . After 3-6months of age Hb A is the dominant hemoglobin, with little measures of hemoglobins F and A2 ( Hofbrand et el, 2001 ) . Normal hemoglobins in grownup human blood are as follows: HbA: ?2 I?2 ( 96-98 % ) HbF: ?2?2 ( 0.5-0.8 % ) Hb A2: ?2?2 ( 1.5-3.2 % ) Sickle cell disease is caused by a permutation at place 6 of a individual amino acid in the DNA sequence of the ? hematohiston concatenation ( fig. 1 ) . The minor alteration of glutamic acid for valine, as illustrated in figure 1, consequences in an altered hemoglobin discrepancy known as the Sickle Hb ( Hb S ) ( Hoffbrand et al, 2001 ) , which reduces the endurance of ruddy cells and causes irreversible sickling of ruddy cells at low O conditions ( Hoffbrand et al, 2001 ) . Consequently SCD patients endure a assortment of symptoms runing from anemia, terrible bone hurting ( referred to as sickle crisis ) , stroke, acute thorax hurting, to multi organ harm ( Gladwin et al, 2008 ) .Amino acidproglugluNormal ?- concatenationBase composing CCT Joke Joke Base composing CCT GTG JokeSickle concatenationprovalgluFig 1. Showing a individual base alteration in the he DNA sequence, where A ( A ) is replaced by T ( T ) . This permutation consequences in an amino acid alteration from glutamic acid to valine in the 6th place. ( Adapted from Hoffbrand et Al, 2001 ) . Normal ruddy blood cells are flexible and round in form. Their flexibleness and form allows them to go freely through little blood vass, known as capillaries ( Hoffbrand et al, 2001 ) . ) . Hb S is indissoluble when exposed to low O environments and may organize polymers which may change the ruddy cell membrane from a biconcave form to a sickle form. In oxygenated environments, sickled molded cells can alter back to the biconcave form ; nevertheless frequent form alterations may do lasting harm doing some cells to stay sickled. ( Hoffbrand et al, 2001 ) . Furthermore, these sickled cells circulate at a slower rate compared to normal ruddy cells and tend to go stuck, therefore barricading vass in the microcirculation and doing infarcts of assorted variety meats ( Hoffbrand et al, 2001 ) .DiscussionSurveies in the last two decennaries were more focused on direction of the return of cerebrovascular diseases ( CVA ) . Recently the focal point is now on forestalling the happening of a fir st CVA ( Ohene-frempong et Al, 1998 ) . Hemolytic anemia is associated to many complications of SCD ( Lezcano et al, 2006 ) . Assorted surveies have linked low Hb, and hemolytic markers such as Retics, LDH, AST and creatinine to cerebrovascicar diseases such as shot. ( Kato et al, 2007 ) . Incidence of ischemic shot is higher in SCD kids impacting about 6 % by the age of 10years ( Howard et al, 2007, Deane et Al, 2008 ) . It is associated with an occlusive vasculopathy impacting the distal, proximal and anterior arterias ( Bulas et al, 2000 ) . The narrowing of these vass may develop over months to old ages before symptoms of a Stroke may happen ( Adams et al. , 1997 ; Bulas et Al, 2000 ) . Designation of hazard factors for shot is of import because it offers the possibilities of forestalling it. Clinical surveies have identified some research lab trials as hazard factors for shot. ( Kirkham et al, 2007 ) , but none has strong anticipation when compared to TCD ( Ohene-frempong et Al, 1998 ) . Surveies by Adams et al 1998 and Lezacano et Al 2006 have shown that the disposal of regular blood transfusion therapy in kids with unnatural TCD measurings reduces both plasma hemoglobin and serum LDH degrees. LDH has long been associated as a marker of intravascular hemolysis by Neely et Al, 1969. Surveies by Ballas et Al, 1991 and Kato et Al, 2006 found serum LDH the dominant biomarker in intravascular hemolysis and besides strong correlativities of LDH with hemolytic markers such as hemoglobin, retics and AST in grownups with SCD. A recent survey by O'driscoll and co-workers done at King ‘s College Hospital in London in 2007 reported that high serum LDH in kids with SCD correlatives to abnormal TCD measurings. This determination suggests that LDH can be a important biomarker or a hazard factor for shot in kids with SCD. They besides reported important correlativities between LDH, Hb, Retics and AST. Furthermore, Rees et Al in 2008 found important correlativities between unnatural TCD consequences and Hb, Retics, AST and age. These happening were used to develop an index which can be used to place kids with SCD probably to hold unnatural TCD values. The survey by O'driscoll and co-workers is the first survey which demonstrates that a high serum LDH degree in SCD kids has strong correlativities with unnatural TCD measurings. Therefore in this survey we aim to utilize LDH as one of the research lab parametric quantities and farther validate the survey at Kings in the patient population at CMH. Extra showing factors for shot are hence needed. With this attack in head, Hb F, Hb S and WBC will besides be analysed in this survey. The importance of WBC arise from observations that high leucocytes is associated to terrible complications of SCD and from findings by Platt et al.,1994 that leucocytosis is a hazard factor in clinically open shot and in acute thorax syndrome ( Ohene-frempong et Al, 1998 ; Mark et al. , 2008 ) . High WBC is reported to correlate significantly with shot ( Frenette et al, 2007 ) , therefore a good parametric quantity to mensurate in this survey. Hb F is said to cut down the hemolysis, thereby cut downing the hazard of shot in kids ( Kato et al, 2007 ) . The genotypes, HBSS and HBSC kids will be assessed to see which group is more at hazard for shot. The current theories of complications of SCD particularly with respects to cerebrovascular disease are largely focussed on hemolysis and the bioavailability of NO. ( Kato et al, 2007 ) . Chronic hemolysis leads to the release of plasma Hb which sucks up NO. NO is a vasodilative, hence less NO in the microcirculation upsets the balance between vasoconstriction and vasodilation which consequence in endothelial disfunction ( Kato et al, 2007 ) . More surveies in understanding hemolysis and the function played by NO will assist in understanding SCD complications and cut down its badness in the hereafter. ( Kato et al. , 2007 ) . Several surveies has suggested that, there is a nexus between shot and hemolysis and that shot is associated with low hemoglobin and compensatory reticulocytes. ( Kato et al.,2007 ) . With that attack, we aim to mensurate the undermentioned research lab parametric quantities: Hb, Retic, AST, Creatinine and LDH and correlate them to abnormal TCD measurings.Future PROSPECTSRecommendations for future pattern to include precedence for TCD scan given to kids who have been identified with these research lab parametric quantities so that primary stroke can be avoided and preventative steps such as, transfusion or exchange transfusion is given. This will so better their attention.

10 Actinium Facts

Actinium is a radioactive metal that is the first element of the actinide series. Its sometimes considered the third element in Row 7 (last row) of the periodic table or in Group 3 (IIIB), depending on which chemist you ask. Here are 10 interesting facts about actinium. 10 Actinium Facts Actinium has atomic number 89, meaning each atom of the element has 89 protons. Its element symbol is Ac. It is an actinide, which also makes it a member of the rare earth element group, which is itself a subset of the transition metals group.Actinium was discovered in 1899 by French chemist Andre Debierne, who suggested the name for the element. The name comes from the Greek word aktinos or aktis, meaning ray or beam. Debierne was a friend of Marie and Pierre Curie. Some sources suggest he worked with Marie Curie to discover actinium, using a pitchblende sample from which polonium and radium had already been extracted (discovered by the Curies).Actinium was independently discovered again in 1902 by German chemist Friedrich Giesel, who had not heard of Debiernes work. Giesel suggested the name emanium for the element, which comes from the word emanation, meaning to emit rays.All isotopes of actinium are radioactive. It was the first non-primordial radioactive element to be isolated, even though other radioactive elements had been identified. Radium, radon, and polonium were discovered before actinium but werent isolated until 1902.One of the more noteworthy actinium facts is that the element glows blue in the dark. The blue color comes from the ionization of gases in the air by radioactivity.Actinium is a silver-colored metal that has properties similar to those of lanthanum, the element located directly above it on the periodic table. The density of actinium is 10.07 grams per cubic centimeter. Its melting point is 1050.0Â °C and boiling point is 3200.0Â °C. Like other actinides, actinium readily tarnishes in the air (forming a white actinium oxide layer), is extremely dense, is highly electropositive, and likely forms numerous allotropes. The other actinides readily form compounds with nonmetals, although actinium compounds are not well-known.Although it is a rare natural element, actinium does occur in uranium ores, where it forms from the radioactive deca y of uranium and other radioisotopes, such as radium. Actinium is present at an abundance of 0.0005 parts per trillion by mass in the Earths crust. Its abundance in the solar system is negligible overall. There is about 0.15 mg of actinium per ton of pitchblende.Although it is found in ores, actinium is not commercially extracted from minerals. High-purity actinium may be made by bombarding radium with neutrons, causing the radium to decay in a predictable fashion into actinium. The primary use of the metal is for research purposes. It is valuable neutron source because of its high activity level. Ac-225 may be used for cancer treatment. Ac-227 may be used for thermoelectric generators, as for spacecraft.36 isotopes of actinium are known—all radioactive. Actinium-227 and actinium-228 are the two that occur naturally. The half-life of Ac-227 is 21.77 years, while the half-life of Ac-228 is 6.13 hours.One interesting factoid is that actinium is about 150 times more radioactive than radium!Actinium presents a health hazard. If ingested, it is deposited into the bones and the liver, where radioactive decay damages cells, potentially leading to bone cancer or other illnesses.

International Trade And Exchange Rates - 2916 Words

Although difficult to establish and measure, a close relationship exists between international trade and exchange rates. UNCTAD (2013) acknowledges that the relative valuations of currencies and their volatility often have important repercussions on international trade, the balance of payments and overall economic performance. This relationship has moved to the center stage of international trade debate following the 2008 financial crisis and the decision by several large countries to maintain undervalued currencies in order to promote exports, in turn stimulating domestic economic growth. Gagnon (2012) sets the landscape, stating that ‘governments are distorting capital flows by around $1.5 trillion per year, in an attempt to hold down the value of their currencies.’ The impact of currency misalignment on international trade has led to global imbalances and many scholars and governments have criticized the World Trade Organization (WTO) for its failure to address this problem. One of the leading scholars in international law, Bergsten (2007) aptly summarizes these concerns stating ‘the failure to link the trade and currency issues is by far the most important single issue facing the global trading system and, indeed, international economic cooperation today’. Whilst various autho rs (Mattoo and Subramanian, 2009; Thorstensten, Marcal Ferraz, 2014) argue that the WTO is the best forum to address issues of currency misalignment owing to its credibility and effectiveness inShow MoreRelatedThe Foreign Exchange Rate On International Trade And Cross Country Investment Essay4627 Words   |  19 Pages1 Introduction The foreign exchange rate is the rate when domestic currency (for example, Chinese yuan) is used to exchange foreign currency (for example, us dollar).
