Nursing assignment - Essay Example Diffusivity of a gas is a physical constant that is derived from calculations based on the solubility of the gas in the membrane and the molecular weight of the gas. The area available for diffusion and the thickness of the membrane is anatomy dependent. Thus the exchange of oxygen from the alveoli to the capillaries is mostly based on the pressure gradient across the alveolar-capillary membrane. The same law applies to the transport of carbon dioxide from the capillaries to the, but carbon dioxide is more soluble than oxygen in the membrane and so diffusion limitation is seldom an issue with carbon dioxide, the elimination of which is dependent heavily on ventilation. (Walley & Russell, 1999). Besides the difference between the partial pressures of the gases in alveoli and the pulmonary capillary bed another important determinant of gas exchange is the relationship between the pulmonary capillary perfusion (Q) and alveolar ventilation (V). A well ventilated alveolus needs to have an equally well perfused capillary, with the ratio V/Q ideally 1. A three compartment model of the lungs helps to understand the perfusion and ventilation relationship. Physiological dead spaces, where exchange of gases does not take place are areas of wasted ventilation, where V/Q is greater than 1. Perfectly matched areas of ventilation and perfusion have V/Q equal to 1. Areas that contribute to venous admixture, which is the mixing of non-oxygenated with oxygenated blood after passing through the lungs, where perfusion has been wasted, in the example of the right to left shunt, V/Q is less than 1. Even in normal lung function, there is a degree of variation in the perfusion and ventilation in different areas of the lung due to gravity, which requires the extra effort in forcing blood supply through the blood vessels above the heart in an erect position. Thus the lower portion of the lobes of the lung is better perfused

Optimizing Cash Management Model With Computer Intelligence
Optimizing Cash Management Model With Computer Intelligence Allià and M.M. Ramya Abstract In todayââ¬â¢s technical era, the financial organizations have great challenges to optimize the cash management process. Maintaining minimum cash leads to customer frustration. At the same time, upholding excess cash is a loss to the organization. Hence, soft computing based cash management solutions are required to maintain optimal cash balance. An Artificial Neural Network (ANN) is one such technique which plays a vital role in the fields of cognitive science and engineering. In this paper, a novel ANN-based cash Forecasting Model (ANNCFM) has been proposed to identify the cash requirement on daily, weekly and monthly basis. The six cash requirement parameters: Reference Year (RY), Month of the Year (MOY), Working Day of the Month (WDOM), Working Day of the Week (WDOW), Salary Day Effect (SDE) and Holiday Effect (HDE) were fed as input to ANNCFM. Trials were carried out for the selection of ANNCFM network parameters. It was found that number of hidden neurons, learning rate and the momentum when set to 10, 0.3 and 0.95 respectively yielded better results. Mean absolute percentage error (MAPE), and mean squared error (MSE) were used to evaluate the performance of the proposed model. MSE that was less than 0.01 proves the capability of the proposed ANNCFM in estimating the cash requirement. Keywords: ANN, ANNCFM , neuron, back-propagation, momentum, learning rate. Introduction: Forecasting cash demand needs to be more accurate for any financial organization including banks [1-3]. If the forecast is flawed, in addition to making financial losses to the banks, it results in customer dissatisfaction. In banking industry, an earlier cash requirement study was made using feed forward neural network with back propagation for short term data of two months [1]. Subsequently another comparative study was made for the cash anticipation using a classic time series models and artificial neural networks [2]. The daily cash requirement models for a bank were optimized with particle swarm and compared with least square method for short term data [3]. The main objective of the paper is to design, develop and test a unique supervised method to forecast the cash requirement for banks from their historic data. 1.1 ANN Background ANN is an efficient tool in understanding the complexities of real world problems in all fields of our daily life[4]. It is used as a function optimizer for linear as well as nonlinear problems in science,engineering,technology,management and finance[5-9]. Artificial neural network learning methods provides the best approach for approximating discrete,real and vector valued target functions [10-12], for complex problems, which are not possible to solve by conventional mathematical methods like analytical and numerical technique. ANN are applied in forex market prediction,portfolio optimization,decision making, metrological parameters forecasting[13-19] etc., The various ANN based approaches applied by researchers in finance field as an alternative to traditional time series model includes Financial and economic forecasting, credit authorization screening, simulation of market behavior, mortgage risk assessment, risk rating of investments and detection of regularities in security price movements [15-19]. 2.0 Design of Proposed ANNCFM Architecture: The process of designing a neural network in many fields resulted in a satisfactory performance but building a neural network forecast for a particular problem is nontrivial task. The modeling issues that affect the performance of the neural network must be selected carefully. 2.1. Selection of ANN Parameters In general, the design of multilayer ANN can have many layers where a layer represents a set of distributed parallel processing nodes. The three layered ANN network with one input, one output and one intermediate hidden layer is sufficient to approximate any complex non-linear function. In the case of forecasting studies many experimental results also confirms ANN with one hidden layer is enough to predict the required data [6-8]. The model architecture of ANNCFM is shown in the Fig1. Fig1: Architecture of ANNCFM Model The important critical decision is to determine the architecture is i) number of layers, ii) number of neurons in each layer, iii) number of arcs which interconnect with nodes , iv) activation function of hidden and output nodes, v) training algorithm, vi)data transformation or normalization, vii)training and test sets and viii)performance measures. 3.0 Design of Proposed ANN Models The proposed ANNCFM model consists of one input, one hidden and an output layer as discussed in section 2.1. In this study the data was collected from a semiââ¬âurban area bank located in India. The typical daily cash requirement for thebank for one year is shown in Fig2. Fig. 2: Typical Cash Requirement for a Year The collected data was for a period of three years (2010 to 2012) and was used for training and testing with the following input parameters: RY- Reference year: ranges between 1 to 3 as three years MOY-Month of the year: ranges from 1to 12, WDOM-Working day of the month: ranging from 1 to 27, WDOW ââ¬âWorking day of the week: ranging from 1 to 6, SDE- Salary day effect: ranging from 1 to 3, and HDE- Holiday and the week end effect: either 0 or 1. The fore mentioned parameters were used as six input neurons. In the hidden layer, the number of neurons were varied from 8 to 50.The output layer had one neuron that corresponds to the optimal cash requirement for a day. 3.1 Pseudocode- ANNCFM Main() { [W, V, Voj, Wok]=ANNCFMtrain( x,nip,nh,op,à ±,à ¼,t) yk = ANNCFMtest(ts, W,V, Voj,Wok,t) [Mserr,Mape]=ANNCFMevaluate() } FunctionANNCFMtrain(x,nip,nh,op,à ±,à ¼,t) returns network with modified weight { Repeat { For each training sample x(I,nip) //Feed forward computation //Determine the output neuron between input layer and hidden layer //Determine the output neuron between hidden layer and output layer //Compute the error signal between the output and hidden layer //Update the weights between the output(k) and Hidden(j) layer; If itr=1 then { else End if } //Update bias between the output and hidden If itr =1 then { Else End if } //Update the weights between the input(i) and Hidden(j) layer; If itr=1 then { Else End if } //Update bias between the hidden and input If itr =1 then { Else End if } } Until mse } Function ANNCFMtest(ts, W,V, Voj,Wok,t ) returns output(y) { For each testsample ts //Feed forward computation //Determine the output neuron between input layer and hidden layer //Determine the output neuron between hidden layer and output layer } ANNCFM evaluate(tk ,yk,ts) { } 4.0 Evaluation Metrics: In order to derive and evaluate the performance of the most appropriate model that fulfils our objective of optimizing the cash management, few metrics were used. The accuracy of the proposed ANNCFM is evaluated using MAPE and MSE which are defined as follows: MSE= Where Xt is the actual data at period t, Ft is the forecast at period, t, et is the forecast error at period t, while n is the number of observations. 5.0 Results and discussion: The data for a period of three years (2010-2012) was collected from City Union Bank (CUB)-ukt bank branch to simulate the network using MATLAB .For the proposed study the total number of data for the three years is 879, in which the first two and half years, 737 data were used for training(80%) and the remaining six months 142 data sets (20%) were used for testing. Studies found that input data normalization with certain criteria, prior to training process, is crucial to obtain good results, as well as to fasten significantly the calculations [J.Sola J. Sevilla]. Hence the input data was normalized before training. In ANNCFM, 15 runs were made by varying the number of hidden neurons from 10 to 50 using gradient descent with momentum back-propagation (traingdm) for the default training parameters learning rate =0.01, momentum=0.95, Goal=0, and number of iterations as 6000, are illustrated in table 1-column2. The convergence of ANNCFM is influenced by number of hidden neurons in which by varying the number of hidden neurons between 10 through 50. The error was minimal when the number of hidden neurons was set to 10, 20, 40, 45 and 50, by achieving a MSE of 0.0079 as observed from column 3 of table 1. As the number of hidden neurons increase, there is a significant increase in the computational time. Hence the number of hidden neurons in the proposed study was fixed as 10. The pictorial representation for the optimal hidden neuron against its MSE are shown in Fig. 3. Fig.3: Optimal Number of hidden neurons. The learning rate ââ¬Ëlrââ¬â¢ arrives at a local optimum for the higher learning rate and global optimum for slow learning process. Different trials were made to identify the optimal learning rate to avoid the unstable condition and fluctuations in the results. Learning rate was varied between 0.1 through 0.5 in which 0.3 yielded an optimal learning rate for the given data set, as shown in Fig-4. Fig 4: Optimal learning rate The momentum plays a vital role in identifying the convergence point. Momentum, when set too low, it may get stuck into local minima, and if it is too high, network will become unstable. So there is a need to identify the optimal momentum value for ANNCFM, various momentum values were tested between 0.8 and 1.0, the trained results shows that the optimal momentum value was 0.95 are shown in the Fig-5 Fig 5: Optimal Momentum rate In the ANNCFM model to train and test the cash requirement for a day, week, month the following parameters values are selected based on their performance from the different number of runs made above: i) the number of input neurons=6, ii) maximum number of iteration=6000, iii) learning rate= 0.3, iv) momentum=0.95, v) transfer function=tansig/tansig (hidden and output layer). The optimal selection of the above parameters helped in improving the performance, by minimizing the error rate. This is evident from Table 1, that shows the MSE achieved before and after parameter selection. Table1: ANNCFM performance for different number of hidden neurons The ANNCFM was used to estimate daily, weekly and monthly cash requirement. The estimated values were compared with the actual values for the testing period are shown in Fig.6a,b,c.for the daily ,weekly and monthly prediction. The obtained results shows the ANNCFM was found to perform reasonably good for all the three models .The weights calculated by our ANNCFM was found to be sufficient for cash prediction in which RY,MOY,WDOM, WDOW are essential parameters, and SDE,HDE are additional parameters .The connection weight approach was used to quantify the importance of input variable [20]. The preference of the input parameters were found based on the weights obtained was evident from Table 2, column-4. Table 2: ANNCFM Weights-Preferences. The input parameters SDE and HDE plays a vital role in daily and weekly model as it was observed from the above table it effectively takes care the need of peak cash requirement at the beginning of every month and during holiday periods. The role of SDE in the weekly cash prediction could be easily understood for the weeks like 1,5,14, where the cash requirement is maximum since the beginning of the month lies within the week. However for the 9th and 10th as well as for the 18th and 19th week cash requirement shows the new month starts between the weeks. The monthly model was plotted for six months as shown in Fig.6c in which the experimental results shows that the estimated values were most influenced by WDOM .The cash required and predicted was minimum for the fourth month in which WDOM was minimum. The MAPE and MSE for ANNCFM are shown in Table 3 . Fig.6-a: ANNCFM ââ¬âDaily Model Fig.6-b: ANNCFM ââ¬âWeekly Model Fig .6-c : ANNCFM ââ¬âMonthly Model Table 3 : MAPE and MSE errors for ANNCFM The comparison made between the actual and forecast data shown from the figures indicates that the six input variables selected in our model is sufficient to identify the cash need which is changing from time to time. 6.0 Conclusion: The observations from the experimental results of this study shows that ANNCFM is a useful tool to predict the cash requirement in emerging banking sector. ANNCFM using feed forward neural network training with back-propagation algorithm optimize the needs of cash on daily, weekly and monthly basis. In the implementation process the data set used for the years between 2010 and 2012 were trained and tested to measure the performance. The input parameters were initialized and different runs were made for the proposed model to find out the optimal number of hidden neurons as 10, momentum as 0.95 and learning rate as 0.3 to train and test the network using sigmoid transfer function. The estimated results were with minimal error for the better performance with an accuracy of 91.23%. References.

Hidden Burden :: essays research papers fc
Hidden Burden In our society we are brainwashed every day and have been since we have exited the womb. What we donââ¬â¢t realize is that we need to train our mind on our own to rise above all the systematically programmed propaganda. Unfortunately, due to this brain washing we are born into, we come packaged and wrapped with the lovely word stereotype; prejudice embedded deep in our mind without knowledge of it until it is confronted and exposed by pure ignorance! Now when you go to a dictionary the first definition most likely to be seen for stereotype is one like so: " ââ¬ân. 1. a process, now often replaced by more advanced methods, for making metal printing plates by taking a mold of composed type or the like in papier-mà ¢chà © or other material and then taking from this mold a cast in type metal. 2. a plate made by this process. 3. a set form; convention" (Websterââ¬â¢s,797). Further down from that definition should be something like: "ââ¬âv.t. 1. to make a stereotype of. 2. to characterize or regard as a stereotype" (Websterââ¬â¢s,797). Although this definition is in a dictionary, the true meaning is far beyond that mild perception. The history of the word itself is a quite interesting one. In English, "stereo" is taken from the Greek "stere" or "stereo" - and which meant solid or solid body. Originally it was used to describe metal printing. "The conversion from printing to human psychology may have been commenced by early Russian neurophysiologists during the Pavlov period when stimulus-response motor mechanisms were being researched in animals and humans. In that sense, "dynamic stereotype" came to refer to the end-result of cortical analysis and synthesis of all stimuli arising from both the external and the internal world if the same response always occurred relative to the same stimulus" (Swann). Stereotype evolved into something all of us recognize, not as a type of printing, but as the negative word and feeling it is today. In society stereotyping is around us constantly. Womenââ¬â¢s issues, homosexual issues, minority issues, everyday someone is confronted with a stereotype. For example, my friend Omar who is African American has been pulled over and harassed by the police for absolutely nothing. I was there and they didnââ¬â¢t even ask me one question. They completely ignored me until I asked them what Omar did wrong. They just replied with "Mind your own business kid!" I never knew what is was to be like in Omarââ¬â¢s shoes that day and I never will.

Retorical Essay
During the mid-20th Century, racism was a huge issue in the United States, which the most prominent was the racism of African-Americans. Although all blacks were supposed to be free, under a corrupt law system, blacks were victimized mercilessly. Therefore, blacks decided to try and change the system and multiple civil rights activists and groups appeared. The most notable activist of them was Martin Luther King Jr. of the Southern Christian Leadership Conference, or the SCLC (Martin Luther King, Jr. Biography).Throughout the 1960s, King engaged in various civil rights boycotts and protests, helping to further the movement and gaining its eventual victory. Out of all of his civil rights-related efforts, the ââ¬Å"I Have a Dreamâ⬠speech, given on the steps of the Lincoln Memorial during the ââ¬Å"March on Washington for Jobs and Freedomâ⬠in 1963 (ââ¬Å"March on Washington For Jobs and Freedom). The speech had a massive impact as it managed to illustrate the racist probl ems of the time and provoke the audience into feeling sympathy while providing hope to the depressed African-American population.Sadly, the speech also made the movement and King very popular, making his opponents treat him as a threat, causing him to be assassinated 4 years later and he was unable to enjoy the fruits of his work. The reason for ââ¬Å"I Have a Dreamâ⬠massive impact is due to the tense social mood of the time and that it reflects the conditions of the time, giving black activists a vision for the future. It struck directly into the hearts of blacks across America, made whites ashamed of their actions and willing to have a new start and shook society to its roots.In just 17 minutes, King influenced and informed the generations and generations of people about racial equality and fairness. According to almost all scholars, the seventeen-minute speech is a masterpiece of rhetoric (Edwards). This is obvious when analyzing the speech as one can notice that King care fully structures his speech to appeal to the different types of audience, supporting it with the three rhetorical modes of ethos, pathos and logos which are reinforced with different rhetorical tropes and schemes, marking Kingââ¬â¢s name in history.The most important of any speech is its structure ââ¬â something which King does extremely well in his speech by showing the plight of the Negroes, showing the truth of the civil rights movement and that there is hope in the future. Basically, the speechââ¬â¢s structure is intended to appeal to the three types of audiences likely to be listening to Kingââ¬â¢s speech ââ¬â the average blacks who are discriminated against, the average whites who harbor thoughts typical of that time and the militant blacks and racist supremacists who argue that blacks are evil and the civil rights movement is violent.In the first part of his speech, King, cleverly paints a picture of the plight of the Negroes and thoroughly describes their co ndition. For example, in the start of the essay, King says that the life of the blacks is ââ¬Å"crippled by the manacles of segregation and the chains of discriminationâ⬠and that the blacks are living on a ââ¬Å"lonely island of povertyâ⬠in the midst of a ââ¬Å"vast ocean of material prosperity. This first makes the whites realize how the blacks are in a terrible plight and make them dislike their actions while striking deep into the hearts of blacks as this clearly paints out their situation. Further on, King continues to emphasize this by continuing to list examples of the Negroesââ¬â¢ problems, which continues to strike at the Negroes as they are stirred by descriptions of their sadness and makes whites uncomfortable as they think that they are the ones responsible for this.Also, King makes references to how America has literally broken their promise to the Negroes by refusing them the rights granted in the Constitution. Therefore, the plight of the Negroes is n ot their fault; it is the fault of the whites. One problem with the civil rights movement, however, is that many enemies of the movement argue that activists of the movement act aggressively and use violent methods to seek their goals. This has caused many people to lose their support for their movement.In order to stop this, King, who was a public face for the movement at the time, states that the Negroes must conduct their struggle ââ¬Å"on the high plane of dignity and disciplineâ⬠and must not allow their ââ¬Å"creative protest to degenerate into physical violenceâ⬠for the ââ¬Å"marvelous new militancy which has engulfed the Negro community must not lead us to a distrust of all white people. â⬠Later, near the end of his speech, King continues to ââ¬Å"preachâ⬠this point, for example by stating that he has a dream that ââ¬Å"little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. Thro ugh this, King intends to say that the black militants are not supported by the majority of the civil rights movement and that the movement is intent on reaching their goals nonviolently. This also has the additional effect making the whites uncomfortable when they think how the blacks are not really the savages they think they are and are instead dignified, honorable people who continue to endure and that the whites are the true savage beasts. However, this is not the end.After portraying multiple examples of white brutality and the pain of the Negro people, however, King knows that it is important to give the Negro people a message of hope. Therefore, at the very end, King starts to talk about the future and how one day, freedom will ââ¬Å"ringâ⬠from all across the United States and how people of all races will be able to ââ¬Å"join handsâ⬠and be ââ¬Å"brothers and sisters. â⬠Overall, King intelligently uses a well-planned structure to manipulate his audience into agreeing with him by painting an image of the Negrosââ¬â¢s plight.In his speech, in order to back up his basic structure King uses rhetorical modes, one of which is pathos, or the mode of utilizing human emotions, by making his audience no longer hate Negroes and instead hate racism and wish for a new, better world, which is part of the structure of his essay. King tries his best in the speech to make the audience sympathize with the Negroes, dislike racism and then be filled with hope of a new world without racism by using strong adjectives and metaphors.For example, King constantly describes the Negroes as being ââ¬Å"crippledâ⬠by the ââ¬Å"manacles of segregationâ⬠and ââ¬Å"chains of discrimination. â⬠Through this, King makes the audience feel that the Negroes are in great calamity; as if the Negroes had committed a crime and have to be restrained, something which King emphasizes on when he compares the situation of the Negroes as to being stranded on a ââ¬Å"lonely island of povertyâ⬠while everybody else around them are indulging in a ââ¬Å"ocean of material prosperity. Therefore, through this, the audience realizes how it is not because the Negroes are stupid that they live in poverty, but because the white American society is literally holding them back. Later, King then aims to make the audience hate racism by giving them a metaphor: that racism is a ââ¬Å"dark and desolate valleyâ⬠while racial justice is a ââ¬Å"sunlit path. â⬠It results in the audience first realizing that their society is in that dark and desolate valley then thinking that without racism, the American society could then climb onto the sunlit path of racial ustice. Throughout his speech, King does this again and again, such as writing that black children are ââ¬Å"stripped of their selfhoodâ⬠and dignity by ââ¬Å"signs stating ââ¬ËFor Whites Onlyââ¬â¢Ã¢â¬ and that black people are ââ¬Å"judged by the color of their sk inâ⬠instead of the ââ¬Å"content of their character. â⬠This all serves to make the audience feel ashamed of racism. Finally, King paints a picture of his vision and hope in the audienceââ¬â¢s mind by repeating ââ¬Å"I have a dreamâ⬠followed by optimist statements, repeating ââ¬Å"Let freedom ring! and that one day all of ââ¬Å"Godââ¬â¢s children,â⬠no matter what their race or color, will be able to be brothers and sisters without racial injustice. Overall, King effectively uses pathos in his speech, guiding the audienceââ¬â¢s feelings to go along his plans and making them sympathize with Negroes, hate racism and be filled with a hope of an equal world. Other than pathos, King also utilizes the other two modes of rhetoric, ethos and logos, the art of using social ethics and logic and examples, although logos is used far less frequently compared to the other two modes.These two modes help in Kingââ¬â¢s structure to make the audience think that t he whites have lied and broken their promises to the Negroes. In the late beginning of his speech of his speech, King writes that when America was founded, ââ¬Å"the Constitution and Declaration of Independenceâ⬠stated that all men, black or white, were to be granted the same rights. However, nowadays, America has not kept its promise to the black people ââ¬â King compares this to having given Negroes ââ¬Å"a bad check,â⬠a check which has come back marked ââ¬Å"insufficient fundsâ⬠despite the ââ¬Å"promissory noteâ⬠of the ââ¬Å"Constitution and Declaration of Independenceâ⬠.Ethically, most people believe that it is necessary to keep a promise. Therefore, this puts racism in a whole new light: that racism is not justified as the US has failed to deliver their promises. This helps in making whites uncomfortable about their actions ââ¬â something important in Kingââ¬â¢s structure. Later on, King mentions that racial equality can only be achi eved until ââ¬Å"justice rolls down like waters and righteousness like a mighty stream. â⬠This deliberately makes the audience think that racial segregation is wrong and against basic moral principles.Finally, King also attacks the enforcers of racial segregation, or the police, by citing ââ¬Å"police brutalityâ⬠and insufficient living conditions for the prisoners. Meanwhile, the one example of logos in the speech is when King refers to the Emancipation Proclamation Lincoln signed 100 years earlier. King writes in the very beginning that ââ¬Å"five score years ago,â⬠Lincoln signed the ââ¬Å"Emancipation Proclamationâ⬠that declared slaves free and blacks were no longer to be treated like property.King uses this piece of evidence to show that even Lincoln, one of the most admired men in US history, supported the freeing of blacks, creating an ethos appeal through the logos of Lincolnââ¬â¢s Emancipation Proclamation. However, there is also a logos appeal as well because when audiences think about it, the Emancipation Proclamation, or the order to free slaves and start of racial equality, had been written a hundred years ago.Yet, in all that time, the idea of racial equality, instead of increasing, had decreased. Therefore, America should start adopting the ideas of racial equality. In summary, Kingââ¬â¢s speech also utilizes the modes of ethos and logos in the first half of his speech as the civil rights movement is based heavily in ethics and to show that Lincoln, one of the most respected Americans in history, supported the freeing of blacks and since it has been one hundred years since the black equality movement really started.To assist in his rhetorical modes, King uses rhetorical tropes in his modes such as when he alludes to several different works like the Bible, Lincolnââ¬â¢s Gettysburg Address and Shakespeareââ¬â¢s ââ¬Å"Richard IIIâ⬠syncing Kingââ¬â¢s ideas with what is considered righteous by many peop le, makes the audience remember important parts of the past and helps audience understand the situation, all of which are important to the success of the speech. An example of this is when King writes ââ¬Å"justice rolls down like waters and righteousness like a mighty stream. This is a direct biblical allusion to Amos 5:24 ââ¬â ââ¬Å"But let justice roll on like a river, righteousness like a never-failing stream! â⬠Another biblical allusion is when King writes that he has a dream that one day, ââ¬Å"every valley shall be exalted,â⬠every hill and mountain ââ¬Å"made low,â⬠all rough places will be ââ¬Å"plainâ⬠and crooked places ââ¬Å"straightâ⬠and that the ââ¬Å"glory of the Lord shall be revealed. â⬠Other than the direct Christian allusion by mentioning God, this phrase also alludes the Isaiah 40:4-5 ââ¬â ââ¬Å"Every valley shall be raised up, every mountain and hill made low; the rough ground shall become level, the rugged places a plain.And the glory of the Lord shall be revealed. â⬠King also alludes to Psalms 30:5 by writing ââ¬Å"It came as a joyous daybreak to end the long night of their captivityâ⬠as the second half of Psalms 30:5 states, ââ¬Å"weeping may remain for a night, but rejoicing comes in the morning. â⬠All these biblical allusions remind the audience that what King says is in accordance to the Bible. Large quantities of the 1960s American population were churchgoers.Therefore, as the audience would all hold the Bible to be righteous, by making the audience think that King words are in sync with the Bible, King manages to make the audience feel as if his arguments are all definitely righteous and should be supported. Another allusion, this time a literary one, is to Lincolnââ¬â¢s Gettysburg Address when King states ââ¬Å"Five score years agoâ⬠at the start of his speech, which is an direct allusion to the phrase ââ¬Å"Four score and seven years agoâ⬠at the start of the Gettysburg Address.Due to the fact that the Gettysburg Address is also about human rights and that most people remember Lincoln as being a staunch supporter of blacks, this allusion makes the audience remember that one of the greatest men in history opposed segregation. The final allusion, also a literary allusion, is when King writes that the ââ¬Å"summer of the Negroââ¬â¢s legitimate discontent will not pass until there is an invigorating autumn of freedom and equality. â⬠This alludes to the opening lines of ââ¬Å"Richard III,â⬠a historical play by William Shakespeare, which are ââ¬Å"Now is the winter of our discontent.Made glorious summer by this sun of York. â⬠In ââ¬Å"Richard III,â⬠the main character, Richard, and his brother, Edward, are constantly in a state of conflict. Therefore, through this allusion, King attempts to make the reader think that the situation between black and white men are the same ââ¬â both are technically ââ¬Å"brothers,â⬠yet are both struggling and fighting against each other. The allusions used by King reinforces his message as they make it seems to be in sync with the Bible and make the audience that like the story of ââ¬Å"Richard III,â⬠black and white men, technically ââ¬Å"brothers,â⬠are battling each other.Through these allusions, King intends to support his ethos as the Bible is a great source of ethics, Lincoln is historically famous for his ethical beliefs and because an allusion to ââ¬Å"Richard IIIâ⬠invokes the ethic that brothers should not discriminate against each other. Metaphors, another useful rhetorical trope, are essential to help audiences fully understand an idea as it compares an idea with something the audience is familiar with, which is important to bring out modes such as ethos and pathos. King uses a series of more complicated metaphors in the middle of his essay.He claims that by ââ¬Å"the Constitution and Declaration of Indepe ndence,â⬠the forefathers of America were ââ¬Å"signing a promissory noteâ⬠that all men, whatever color, would be granted the same rights. However, King then says in the view of the Negroes, the US government have given the Negroes a ââ¬Å"bad check,â⬠a bad check that does not promise them the same results that have been given to the white population. Later on, King says that many equal rights activists have been ââ¬Å"battered by the storms of persecutionâ⬠and the ââ¬Å"winds of police brutality. Through this metaphor, King paints the upholders of the Jim Crow laws, the laws suppressing blacks (Jim Crow Laws), in a bad light. These two metaphors both relate to ethos as the first metaphor invokes the ethic of keeping your promises while the second metaphor involves torture, something which most of the American population was against. Finally, King uses several last metaphors when he writes that with faith, it is possible to transform the ââ¬Å"jangling di scordsâ⬠of our nation into a ââ¬Å"beautiful symphony of brotherhood. This metaphor, on the other hand, is related to pathos as the audience immediately feels good due to the Kingââ¬â¢s choice of words. All of these metaphors are aimed to make the audience realize that continued racial injustice will lead to total chaos while racial equality leads to a beautiful society. Overall, the metaphors King uses are effective to support the ethos and pathos as they make the audience realize that the US have cheated the Negroes, that those who uphold the Jim Crow laws are evil and that it is possible to transform the US society.Like the metaphor, the simile is useful to help the audience understand ideas and is also part of the rhetorical modes. Examples of the simile in Kingââ¬â¢s speech is when he writes that the Emancipation Proclamation came ââ¬Å"as a joyous daybreakâ⬠to the black slaves to end the ââ¬Å"long night of their captivity. â⬠This simile tells and em phasizes to the audience how the Emancipation Proclamation was a great ââ¬Å"beacon of hopeâ⬠to the slaves and how they rejoiced when the received the news.Therefore, this also helps to make the audience delighted and happy for the Negroes, which means they become saddened when King tells them how 100 years later, the Negroes, however, are still not free. Also, this simile fits the mood of the speech as the speech occurred near the Lincoln Memorial. King implies to this by writing that the Emancipation Proclamation was signed by a ââ¬Å"great Americanâ⬠whose ââ¬Å"symbolic shadowâ⬠they stand in. Other similes are ââ¬Å"justice rolls down like watersâ⬠and ââ¬Å"righteousness like a mighty stream. These similes intend to tell the audience that King and his friends will not stop until justice comes down and sweep away all racism and injustice King also uses a rhetorical question, the final trope in his speech -ââ¬Å"when will you be satisfied? â⬠in h is speech in order to trigger a flood of answers and to stir up the feelings of blacks. In the middle part of his speech, King writes that some whites ask black activists when blacks will be satisfied. King then writes that blacks will not be satisfied as long as there is racism.First, King is answering many whites: blacks will not be satisfied until everybody is equal. Then, King stirs up the feelings of the blacks with his question when he includes all sorts of examples of racial injustice to colored people when he answers himself. This is intended to support pathos as it is effective in stirring up the black audienceââ¬â¢s feelings and anger. The rhetorical question is useful to King because they answer questions posed by the whites and stir up the Negroesââ¬â¢ feelings about racism.Other than tropes, though, King uses schemes as well, such as epistrophe. He uses epistrophe when he writes ââ¬Å"With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day. â⬠Epistrophe, which is when a certain word at the end of a clause is repeated again and again, is effective in this case as it puts emphasis on the fact that the civil rights movement will always work together and will never forget or leave anybody to suffer alone.Without this, many civil rights activists might come under the impression that they have been forgotten whenever they got arrested or prosecuted and would stop working for the civil rights movement. King utilizes this to support his pathos as it effectively motivates the civil rights movement. Therefore, the world is informed that the civil rights movements are united together and to all activists they are not alone. Martin Luther King uses anaphora multiple times in his speech as it is also closely related to the rhetorical mode of pathos.Examples are when he repeats ââ¬Å"One hundred years laterâ⬠three times in one paragraph and ââ¬Å"Now is the timeâ⬠four times in another paragraph. Through constant repetition, King aims to emphasize his point in the readerââ¬â¢s mind. Another example, when asked when Negros will be satisfied, King repeats ââ¬Å"We will not be satisfiedâ⬠multiple times, followed by an example of injustice suffered by African-Americans ââ¬â which impresses on the audience (this was broadcast on live TV as well) that blacks will not stop until they are not discriminated against.Other than those occasions, there are other examples, such as when King writes ââ¬Å"I have a dream that one day this nation will rise up and live out the true meaning of its creedâ⬠¦Ã¢â¬ ââ¬Å"I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhoodâ⬠¦. every valley shall be exaltedâ⬠¦and the glory of the Lordâ⬠¦shall see it tog ether. â⬠By repeating ââ¬Å"I have a dream,â⬠King emphasizes the fact that he can see a new America, an America free from racial injustice and cruelty.King also writes how ââ¬Å"let freedom ring from the prodigious hilltops of New Hampshireâ⬠¦from Stone Mountain of Georgiaâ⬠¦Lookout Mountain of Tennesseeâ⬠¦hill and molehill of Mississippiâ⬠¦let freedom ring. â⬠The anaphora used here emphasizes Kingââ¬â¢s point and wish for freedom from all parts of the nation, evidenced by how he references to places all over America. It also backs up Kingââ¬â¢s pathos as the constant repetition is very useful for arousing the audienceââ¬â¢s emotions, especially when combined with the moving content anaphora is often used in conjunction with.Overall, the multiple use of anaphora in Kingââ¬â¢s speech emphasizes the point to the audience that the blacks will not stop until the Jim Crow laws are gone and that when those laws are gone, a new America will e merge. Throughout the speech, another scheme King uses frequently is parallelism, the strategy of repeating similar clauses, several times. Parallelism is useful to emphasize things and ideas to the audience, which, like all the other tropes and schemes. Early in his speech, King writes ââ¬Å"riches of freedomâ⬠and ââ¬Å"security of justiceâ⬠and then ââ¬Å"justice rolls down like watersâ⬠and ââ¬Å"righteousness like a mighty stream. In these two examples, King is using parallelism to express that the African American wants justice and freedom by repeating them next to each other and mentally connecting them in the readerââ¬â¢s mind, which is also connected with pathos as the terms King uses subtly emphasize those words and create good feelings in the reader. As campaigning Negroes have been prosecuted by the police, King makes a mention of them when he writes that those activists have been ââ¬Å"battered by the storms of persecutionâ⬠and ââ¬Å"stagge red by the winds of police brutality. This emphasizes to the audience that many racial demonstrators, despite being brutally treated (which supports ethos as it is a reference to police brutality), have not given up on their efforts. At the end of his speech, King uses parallelism two more times when he writes ââ¬Å"Let freedom ringâ⬠multiple times followed by ââ¬Å"from (American place name). â⬠King decides to again emphasize the importance of freedom by using parallelism and by mentioning place names to implant in the reader of how they should ââ¬Å"let freedom ringâ⬠from across the US.Finally to cap his speech King writes how one day when ââ¬Å"all of Godââ¬â¢s children,â⬠no matter if they are ââ¬Å"black men and white men, Jews and Gentiles, Protestants and Catholicsâ⬠will be able to sing together ââ¬Å"in the words of the old Negro spiritual, ââ¬ËFree at last! Free at last! Thank God Almighty, we are free at last! ââ¬â¢Ã¢â¬ In thi s case, King expresses how all people in the world, despite their differences, are Godââ¬â¢s children and should not be discriminated against by putting almost all of the different groups of people together in a parallel structure.Both of those two final examples are pathos-related as the first example creates good feelings and is inspirational while the final example creates hope for the future in the audience. In summary, parallelism connects different points and, like all other devices, tells the audience of how blacks want justice and that how all people of the world should not be discriminated against. Antithesis is when two utterly different ideas are put together, which is useful for grabbing attention and emphasizing.King uses it in his speech in order to express all his points. First, King writes that ââ¬Å"the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. â⬠This antithesis makes the audience realize that the Negroe s have been left behind and ignored while the rest of modern society has charged forward into prosperity and fortune. From this revelation, the audience will also realize that it is no fault of the Negro that they have been left behind ââ¬â in contrast, modern society have been dragging them back through racism.In order to dispel any misguided ideas that whites have of the Negroesââ¬â¢ fortune, King tells them directly that Negroes are in poverty as everybody is blocking them from entering the ocean of ââ¬Å"material prosperity. â⬠The second time King uses antithesis is when he states that ââ¬Å"Nineteen Sixty-Three is not an end, but a beginning,â⬠which he aims to express that the revolution will not stop at 1963; rather it will have a new beginning. Finally, King uses antithesis one more time at the end of his speech, when he writes ââ¬Å"when all of Godââ¬â¢s children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands. The pairs he mentions are all the direct opposites of each other, yet he says that they will all join hands together and be friends. King implies that one day, all differences will fall away as, no matter what our race and color, we are Godââ¬â¢s children. Overall, antithesis is used by King to grab the audienceââ¬â¢s attention and emphasize to them that the Negroesââ¬â¢ poverty is the fault of the whites, that the revolution will not end at the Washington march and that all men are Godââ¬â¢s children.Finally, the last scheme used by King is the isocolon, or repetition of grammatical structure in several clauses, as it builds rhythm and can be used to connect ideas. An example of this is when King writes ââ¬Å"Go back to Mississippi, go back to Alabama, go back to South Carolina, go back to Georgia, go back to Louisiana. â⬠Through this use of isocolon, King lifts the hearts of blacks and tells them not to give up and continue their cause as someday, th e blacks will be free from discrimination.Although those place names King mentions means nothing to the bystander, the audience King was facing would have recognized them as places where segregation was strictly enforced. Another example of isocolon is in the final part of Kingââ¬â¢s speech, when he writes ââ¬Å"from every village and every hamlet, from every state and every cityâ⬠after writing about freedom ringing from all parts of America. This isocolon simply summarizes his claim of freedom ringing everywhere. It creates a good rhythm and connects ideas.These two usages of isocolon are intended to boost the pathos of Kingââ¬â¢s speech as they both boost the emotions of the audience. Overall, King uses the isocolon to tell blacks to never give up as one day, freedom will ring everywhere. Although all of the rhetorical strategies are interesting, the most important aspect is how they relate to each other and the effect they create. As the structure of ââ¬Å"I Have a Dreamâ⬠is vital to its success, King carefully tries to relate all of his rhetorical strategies with his structure.For example, part of Kingââ¬â¢s structure is intended to make the audience harbor bad feelings about racism. To achieve this, King uses the rhetorical strategy of pathos along with metaphors and other rhetorical tropes and schemes to make the audience feel for the blacks. Also, King carefully chooses the rhetorical strategies in his essay in order to make them fit with the structure. For example, anaphora and parallelism combines in the speech to create the famous ââ¬Å"I have a dreamâ⬠and ââ¬Å"let freedom ringâ⬠repetition.The constant repetition coupled with Kingââ¬â¢s deep inspirational voice serves to inspire the audience, audible when cheers are heard in the recording of Kingââ¬â¢s speech as he says ââ¬Å"I have a dreamâ⬠and ââ¬Å"let freedom ring. â⬠After hearing these repetitions, the viewer is filled with hope. This is in alignment with Kingââ¬â¢s structure as King intends for the end to be about hope for the future and those two repetitions both occur at the end. In brief, the rhetorical strategies of Kingââ¬â¢s speech combine to create a combining effect, supporting and reinforcing each other.In conclusion, Martin Luther King, Jrââ¬â¢s most famous speech was the ââ¬Å"I Have a Dreamâ⬠speech given in 1963 during one of the most famous marches in history, the 200,000-strong ââ¬Å"March on Washington For Jobs and Freedom. â⬠At the time, America was in the grips of racism and segregation, making the lives of many blacks living hell. ââ¬Å"I Have a Dream,â⬠however, played a major step into changing it. It managed to inspire a generation of blacks to never give up and made thousands of white Americans bitterly ashamed of their actions, forging a new start for society.Even now, it continues to make generations of people, not just Americans, to give up their racist beliefs and advocate social colorblindness. Without King, America would be probably still heavily segregated. Other than the speechââ¬â¢s heartwarming and moving content, Kingââ¬â¢s effective structure along with the usage of all three rhetorical modes and certain rhetorical tropes and schemes has revealed the reason ââ¬Å"I Have a Dreamâ⬠as a masterpiece of rhetoric and it persuades hundreds of thousands of people support the blacks instead of treating them unfairly.Works Cited Edwards, Stevie. ââ¬Å"Analysis of Martin Luther Kingââ¬â¢s I Have a Dream Speechâ⬠presentationmagazine. com.

Picaresque Novel
Callie Dahlhauser Lora Devereaux Composition II April 3, 2013 A Picaresque Novel The picaresque novel is an early type of novel originating from the Spanish word picaro. Picaro means a rogue or an adventurer. This type of novel describes the journeys that the main character or ââ¬Å"picaroâ⬠take part in. The main character is usually of low social class and manipulates their way through life instead of working for what they want.The main point of the picaresque novel is to present the main character and reveal his/her adventures (Murfin). There are seven key qualities that determine if a novel is picaresque or not. First, the novel will tell of the rogueââ¬â¢s life usually in first person. Second, the rogue comes from low social class and is very basic. Third, the novel is made up of ââ¬Å"episodesâ⬠that are put together to create the whole. Forth, the main character will not change personality throughout this story. Fifth, the novel is going to portray realism. Sixt h, the picaro does not engage in criminal activities.Seventh, there is a variety of social classes thrown in throughout the novel (Harmon). Picaresque novels are told in first-person point of view and discuss thoroughly the social class of the characters. The picaresque novel is very much discontinuous and structureless. The point of this type of novel is to address the life story of the mischievous main character. This character relies on his intellects to get him far in life rather than hard labor. This adventurous character participates in escapades where he barely succeeds to escape ( Harmon).In a picaresque novel, the central character does not develop into someone else. They start of being a picaro in the beginning and end the same way. They describe the life of the rogue or even just part of their lives. Their qualities stay the same as does the main characters social status. As mentioned before, these types of novels lack structure and usually involve unrelated parts that co me together as a whole (Murfin). Many classify picaresque novels to be romantic because of the adventurous storyline.The picaresque novel however is actually marked as being realistic. Because of the fact that the settings in these stories are very life-like, it gives the novel a realistic texture. The novel is presented with simplicity of language also. It can also be considered realistic because of the in depth detail that is portrayed throughout the novels (Bloom). The rogue in these novels usually does not involve themselves in criminal mischief. They lack virtue which means they rely on tricks and pranks to get them what they want.Many times if the picaro is employed they do tedious work and do not fully apply themselves. In these novels, there is no plot. The story is made up of loosely connected adventures and stories (Harmon). One example of a picaresque novel is Mark Twainââ¬â¢s Adventures of Huckleberry Finn. Huck Finn is the picaro in the story and the novel tells of h is adventures. He was born of the low social status and wandered into danger during his adventures. Huck fits the definition of a rogue because of the fact that he is a loner.He feels more comfortable on his own and away from societyââ¬â¢s cruel judgments (Bloom). Another great example of a picaresque novel is The Unfortunate Traveller, or, The Life of Jack Wilton. This is considered the first English example of a Picaresque novel. The narrator, Jack Wilton, tells of his adventures throughout the wars against the French. He describes the dangers he encounters and the tragedy that he witnesses. Another way that makes this novel picaresque is because of the fact that Jack Wilton travels and comes into contact with many different societies (Bloom).Another example of a picaresque novel is One Flew over the Cuckooââ¬â¢s Nest by Ken Kesey. It is considered picaresque because of the corrupt society and the humor seen throughout the novel by the picaro. Randle McMurphy is the novels m ain character and picaro. During the novel, he is faced with many different challenges. One Flew over the Cuckooââ¬â¢s Nest tells of his adventures of being in the mental institute and describes his carefree personality ( Bloom). Although picaresque novels came about in the 16th century, the picaresque genre is still used frequently today.Picaresque novels have greatly influenced literature (Bloom).
