Character Analysis Essay Essay Example

Character Analysis Essay Essay Peter Brownrigg, a 14-year-old boy who lives in Cumberland in the north of England, is involved in a secret night protest against the theft of his villages farmland by Sir Philip Morton. He leaves his village to escape prosecution for throwing a rock at Sir Philip Morton. He first goes to Penrith, but unexpectedly encounters Sir Philip at a performance of Richard III by a touring playing company. He hides from him in a prop coffin (supposed to contain the body of King Henry VI) which is later carried on to the companys cart. The players discover Peter hiding and the kindly Desmonds, who run the playing company, take him on as a boy actor. Another boy, Kit Kirkstone, also joins the company. Kit proves excellent at playing female roles while Peter acts as an understudy. After Peters jealousy leads to a fight, he discovers Kits secret. Kit is actually a girl in disguise, really called Katharine Russell, who is running away to avoid a forced marriage to Sir Philip, who is only interested in her inheritance. The company breaks up and the Desmonds promise to take Peter and Kit to a London theatre company. When Mr. Desmond breaks his leg in a river accident, the youngsters go on ahead. However, Kit almost reveals her true identity to a crowd of observers after swimming down the river to rescue Mr. Desmond but Peter distracts everyone and saves her. After being initially turned away by Richard Burbage of the Lord Chamberlains Men, they are accepted as apprentices by the playwright William Shakespeare, who recognises Kits acting ability and Peters gift of mimicry. They perform in various plays and see Sir Philip in the audience during Romeo and Juliet. Peters copy of Shakespeares new play Henry V is stolen by the Yellow Gentleman, and Kit and Peter worry that he plans to profit from the unpublished play.

He also notices an odd poem written on the script. He realizes that some of the underlined words found in this poem must be part of a code but has no idea how to decipher it. Peter and Kit finally decode the poorly written sonnet, discovering that the first letter of each line spells SEND NEWS BY PEEL. They immediately associate this message with Sir Philips old peel tower and set off to inform the Queens Secret Service. After meeting the head of the Queens Secret Service, Kit and Peter travel back to Peters village in disguise with one of the Queens spies, Tom Boyd, to follow a clue which leads to Sir Philips peel tower. Tom is killed by the conspirators. Peter is captured but not before learning that John Somers, an actor in their company, is to shoot the Queen during the first performance of Henry V. This is part of a wider conspiracy to install a new regime in England, the rest of it is vague but they are evidently in league with Spain. He is taken for questioning to a deserted Ullswater islet but manages to knock out the guard. He swims to the mainland and narrowly escapes across the fells. Kit and Peter go to a local magistrate, but discover he is a part of the treasonous plan. They steal his horses, which are of exceptional quality, intending to ride to London to warn the Queen. Sir Philip and his associates give chase. On the road they meet Desmond and the rest of the company who are rehearsing Edward II. On hearing of the conspiracy, Desmond vows to stop Sir Philip. The actors dress up in their soldier costumes and rig the horses to sound like an army ready to attack, with trumpets and drums behind. Kit and Peter pretend to be captives so Sir Philip will dismount, and he and his followers are then taken into custody by Desmonds men. Kit and Peter make a desperate dash back to London, and John Somers is captured by guards moments before he can shoot. Kit and Peter meet the Queen and tell her their adventures. In the last paragraph, Peter finishes writing the story and we learn that he and Kit are now married with two sons and living in a lakeside house in Cumberland which is Kits inherited estate.

Free Essays on Task And Risk Management

Introduction: The overall needs of the agency are an important factor in the benefits identification process. Before determining that the most cost-effective way to support staff is to buy new PCs every 4 to 5 years, evaluate the cost of that life cycle against the agency budget and overall priorities. The cost effectiveness of the life cycle is important, but a critical part of evaluating cost effectiveness is how much it allows you to support direct accomplishment of the agency's goals. Technology supports an agency's mission, and management policies must reflect that role. The development of policy for desktop and laptop technology acquisition should be centralized under the authority of the Information Resources Managers (IRM). Decentralized decisions about PC purchases can lead to the proliferation of multiple platforms and models that the agency must support. If separate divisions can order PCs without involving the technology staff tasked with supporting the equipment, it will not be possib le to develop an effective life cycle policy or process. Developing PC life cycles gives agencies the chance to assess their current processes and identify potential areas of improvement. To set a life cycle for commodity equipment such as desktop and laptop computers, a preliminary step is to understand the current situation, so areas where improvement is most needed, can be base lined and quantified. This justification is important to acquiring management support.

Type of Person Essay Example | Topics and Well Written Essays - 500 words

Type of Person - Essay Example According to my test results, I am more Extraverted. As I understood the test and its typological theory background, moderately expressed extravert would mean that I am more into action. I draw energy from action. The higher is the level of energy that I see from people around me, through their reactions and actions, the more I am interested and motivated. The term moderate could mean that I am at the middle range, probably 40-60% since my percentage shows a 44% on this area of testing. Further readings on this type of personality test made me understand that I desire breadth and are action oriented. Being extraverted doesn’t follow that one is a bad girl or bad boy type. They could be more action oriented and are more expressive, not really shy but not arrogant either. Slightly expressed sensing personality could first be understood by the word slightly. Slightly because of the rate or percentage of score that I got. This area of testing measures the way I get or gather information from the world around me, either through reading, the television, or through the people around. My perception and understanding or the information that I have gathered is mostly based on my senses. In my various readings, it was stated that people who uses their senses to gather information prefer to trust that information which is in the present, tangible and concrete. Which is why, details and facts associated with that particular information is necessary for it to have meaning and be taken seriously. Slightly expressed feeling personality is the third area of the personality test result. This now deals with how I decide on things, or simply put as decision making. Typically, both thinking and feeling are important to be able to make a fair judgment or wise decision as based on the data and information gathered or presented. Slightly expressed feeling would then again mean that I am inclined to feeling more of the situation and decisions that I would make. By

Figure 8: (a) CSF pulsation-related artifact in the phase encoding direction in T2-weighted image while (b) show reduction of flow artefact 1.0 INTRODUCTION Magnetic Resonance Imaging (MRI) is one of the medical imaging and diagnosis technique which widely used due to its capability to produce high resolution of cross- sectional anatomical images and high tissues contrast. Eventhough MRI has various advantageous features, but still there are numerous sources of artifacts either patient-related, signal processing-dependent and hardware (machine) related (Erasmus, Hurter, Naudà ©, Kritzinger, Acho, 2004). Definitely, artifacts can degrade the image quality and may mimicking pathology or obscure the abnormalities which can lead to misdiagnosis of MRI images. The MRI artifact can be defined as a structure or feature appearing in MRI image produced by artificial means which is not originate within the scanned object (Erasmus et al., 2004). Commonly, MRI artifacts can be caused by RF leakage, aliasing, patient motion, Gibbs, truncation, chemical shift, magnetic susceptibility and flow motion. 2.0 MRI ARTIFACTS 2.1 RF leakage Cause This artifact also known as Zipper artifact. It occurs when there are leakage of RF or electromagnetic energy generated from certain equipment into MRI system (Stadler, Schima, Ba-Ssalamah, Kettenbach, Eisenhuber, 2007). This extrinsic RF came at a certain frequency then interferes with MRI signal produced by patient. The potential sources of the extrinsic RF are due to penetration of the RF into the shielded scanning room especially when the door is open during images acquisition (Ruan, 2013). After that, the RF will be picked up by the receiver chain of the image sub system (Zhuo Gullapalli, 2006). This RF perhaps generated by radio, illumination or electronic device such as monitoring equipment in the surrounding (Stadler et al., 2007). Remedy In order to overcome this artifact, the operator should identified and eliminate the possible source of the penetration. It can be done by ensure the door of the MR room remain closed during scanning, use only MR compatible MR monitor equipment, and remove the external RF source from the surrounding (Ruan, 2013). Figure 1: Zipper Artifact may appear as horizontal line across the image (Allen, n.d.). 2.2 Aliasing Cause Aliasing or wrap around artifacts can be describe as an artifacts that caused by anatomy that lies outside of field of view (FOV) mismapped within the FOV (Westbrook, Roth, Talbot, 2011). This is because of improper selection of parameter in MR systems especially FOV. The FOV in MRI means the anatomical area that should be covered or imaged during scanning (Morelli et al., 2011). When the selected FOV is smaller than the size of area that should be imaged means the data are under-sampled (Ruan, 2013). Therefore, there are high chances for signals from the outside FOV falsely detect then create an interference with signal within FOV and encode on the reconstructed images thus ‘wrap around’ to the opposite side of image which become aliasing artifacts (Erasmus et al., 2004). Westbrook et al., (2011) state that aliasing artefact can happen along frequency encoding axis (frequency wrap) and phase encoding axis (phase wrap). Remedy Basically, this aliasing artifacts can be eliminated through increase the sampling rate or oversampling along the frequency direction (Westbrook et al., 2011). However, high pass and low pass filter should be used as well in order to filter out frequency outside the FOV which can increase noise in image (Hiroshi, Schlechtweg, Kose, 2009). Besides that, selection of receiver coil which unable to excite or detect the signals from anatomical tissues that lying outside the FOV also important to minimise the artifacts (Ruan, 2013). Lastly, No Phase Wrap (NPW), Phase oversampling or Fold Over supression techniques is also preferred to avoid aliasing artefact by oversamples in phase direction, thus, the phase curve get to extends and cover wider signal producing structures (Westbrook et al., 2011). Figure 2: The part of the body that outside the FOV is mismapped within the FOV and located at the opposite side of the image (Prashant, 2014). 2.3 Patient motion Cause Patient motion artifact is a very most common artefact in MRI. It is caused by movement of anatomical structure during imaging sequence (Zhuo Gullapalli, 2006). There is a broad range of examples of structure movement such as heart or arterial pulsations, respiration process, peristalsis, tremor (Parkinson’s disease) and gross movement of patient (Stadler et al., 2007). Hence, if there is a scanned anatomical part moved during the scanning, the phase gradient cannot predict and encode the signal, thus, that structures will be misplaced in phased encoding direction. As a result, it will causes MR images shown the appearances of mismapping, blurring and ghosting artefact within it (Westbrook et al., 2011). Remedy There are several ways to eliminate or avoid the patient motion artifacts. The remedies are nullifies signal by applying pre-saturation pulses over the area which have potential to produce artifacts (Stadler et al., 2007). This way is more effective to prevent ghosting during patient swallowing. Besides that, Westbrook et al (2011) proposed that attaching a set of bellows over patient’s chest in respiratory compensation which is also known as respiratory ordered phase encoding (ROPE) might help to minimize ghosting in longer sequences while in short sequences, cooperation from patient to hold their breath during scanning is preferred. Next,cardiac gating also plays role in reducing this kind of artefact. For example, electrocardiogram (ECG) gating used to monitors cardiac motion that trigger the excitation pulse. Hence, each excitation pulse in each slice can be timed and acquired at the same phase of cardiac cycle (Westbrook et al., 2011). In the other hand, asking for patient cooperation for keeping still, clear explanation about procedures, and optimize the patient’s comfortability are important to make them immobilize during scanning (Hiroshi et al., 2009). Figure 3:The appearances of ghost lines at the anterior to the abdominal wall indicate as motion artifact because of breathing (Zhuo Gullapalli, 2006). Figure 4: Image shown the effect of head movement or motion during MR scanning (Hornak, n.d.) 2.4 Gibbs Truncation Cause Truncation artefact also can be called as Gibbs Ringing artefact (Czervionke, Czervionke, Daniels, Hauhgton, 1988). Its happen as result of It is causes by abrupt undersampling of data that results in incorrect representation of high and low signals interfaces (Westbrook et al., 2011). That problems lead to visibility of fine lines in MR image and also respectively caused by incomplete digitization of the echo (Ruan, 2013). However, according to Erasmus et al.,(2004), alternating dark and bright lines may visible in image due to a sharp transition in signal intensity. Remedy In order to correct this type of artefact, there are several ways that can be used. For example, increase the matrix size, 256 x 256 instead of 256 x 128 (Westbrook et al., 2011). Next, applying various filters to k-space data before Fourier transform also should be considered (Erasmus et al., 2004). Besides that, provide more phase encoding steps also preferred to make truncation or gibbs artifacts less intense and narrower (www.mr-tip.com, n.d.). Figure 5: Bright and dark lines are visible in image parallel and adjacent to the outer convexity of calvaria (Prashant, 2014). 2.5 Chemical Shift Cause This type of artifact commonly found in MRI image of abdominal and spine imaging. Since fat and water each consist of hydrogen protons but different combination of molecules, fat contain hydrogen binds with carbon,while in water, hydrogen combine with oxygen (Westbrook et al., 2011). Hence, that different chemical environment exist shown that there are different precession frequency between fat and water which fat has lower precessional frequency rather than water (Erasmus et al., 2004). Based on the Larmor equation, precessional frequency is proportional to the strength of magnetic field (Westbrook et al., 2011). Therefore, this chemical shift can become artifact due to that difference of the precessional frequency between fat and water at higher field of magnetic strengths during the frequency encoding or slice-select directions (Ruan, 2013). That frequency is basically used to encode their spatial positions, thus, any chemical shift can lead to spatial misregistration of the MR si gnal (Morelli et al., 2011). MR images will show the bright or dark outlines at fat-water interfaces as the artefact. Remedy To avoid this artefact , a few remedies should be considered such as perform scanning at low magnetic field strength, increase the receive bandwidth in keeping with good signal-noise-ratio (SNR) (Westbrook et al., 2011) . It is also suggested to use minimum FOV as possible. Lastly, swapping phase and encoding direction also may useful to reduce this artefact (Hiroshi et al., 2009). Figure 6: Arrow show dark line at the interface of fat and water indicate as chemical shift artefact (Javan, Rear, Machin, 2011). 2.6 Magnetic Susceptibility Cause Susceptibilty can be refer as characteristic of substance which be magnetized when exposed to magnetic field (Gary, n.d.). MRI physics explain magnetic susceptibility artifacts normally happens because of substance or material especially ferromagnetic materials and also at air-tissues interface which have different degree of magnetic susceptibility that can distort the external magnetic field when placed in large magnetic field. Besides that, the differences also lead to magnetic field inhomogeneity at the scanner region resulting in spins dephase faster and frequency shift between surrounding tissues (Zhuo Gullapalli, 2006). Artifacts in the image will appear as bright and dark areas with spatial distortion of anatomical structures (Stadler et al., 2007). Remedy Generally, these artifacts can be reduced by ensure all metal objects that attached to the patient has been removed before the scan. Next, spin echo sequences are more preferred to be used instead of gradient echo because it use 180 ° RF rephasing pulse which ideal at compensating for phase differentiation between fat and water (Westbrook et al., 2011). Since fast spin echo techniques also contribute in reduction of this type of artefact, hence, short TE is used along with spin echo (Stadler et al., 2007). Metal Artefact Reduction Sequence (MARS) technique can be used in order to minimize the size and intensity of this artifact which developed by magnetic field distortion by introducing an additional gradient following the slice gradient during frequency encoding gradient is used (Olsen, Munk, Lee, 2000). Figure 7: MR image shown massive distortion of magnetic field due to implanted dental retention system (Schubert, 2012). 2.7 Flow Motion Cause Flow artefact can be categorized as one kind of motion artefact which mainly caused by natural motion of liquids such as blood or cerebrospinal fluid (CSF) in the body. For example, hydrogen nuclei in blood flow within the scanned slice may trigger excitation from an incoming RF pulse, however, the signal perhaps cannot be readout due to possibility of that flowing blood have left the slice (Hiroshi et al., 2009). As a result, vessels image appear empty or low signal intensity (less bright). Generally, there are reasons of low signal intensity such as intravascular signal void by time of flight effects, first echo dephasing and fast flow (Hiroshi et al., 2009). Nevertheless, this artifacts also can appear bright or high signal intensity. This is because of the slow blood flow (flow related enhancement), even echo rephrasing and diastolic pseudogating (Hiroshi et al., 2009). Remedy The preferred solutions as remedies for flow motion artifacts are by reduction of phase shifts using flow compensation in order to produce gradient moment nulling, suppress the blood signal by apply saturation pulses parallel to slices and synchronization of imaging sequences with cardiac cycle using cardiac triggering (Zhuo Gullapalli, 2006). Figure 8: (a) CSF pulsation-related artifact in the phase encoding direction in T2-weighted image while (b) show reduction of flow artefact with gradient moment nulling (Morelli et al., 2011). 3.0 CONCLUSION It is important for all operators, radiologist and engineers in MRI are able to recognize common MRI artifacts because there are a broad of range of cause that contributing to artefact. Eventhough, artifacts are unable to be totally eliminated but it can be minimized or avoided with specifics remedies in order to improve the MR image quality (Morelli et al., 2011). Therefore, basic knowledge of MRI artifacts should be learned and all MRI system operators should familiar with their MRI unit in department. 4.0 REFERENCES Allen, E. D. (n.d.).

The Physics of Basketball Essay examples -- Science Sports Athletics E

The Physics of Basketball There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing. The most important part of the game of basketball is shooting the basketball, after all the object of the game is to put the basketball through the basket. A shot is taken by a player pushing on the ball and launching it toward the basket and upon the ball hitting the rim or backboard physics refers to this action as a contact force. Using this concept of contact force a shot can be calculated exactly. From a player’s height, the mass of the ball and a given position on the court which would include the distance from the basket it is possible to calculate the exact angle and force the shooter must apply to make a basket every time he or she shoots the ball. Of course if it were this easy basketball would not be as fun to watch or play. The problem with hitting a shot every time with the calculated angle and force is that the ball would have to travel toward the basket with the exact angle and force calculated for that particular shot. What makes this difficult is that the musc les in our body would have to be controlled flawlessly to push the ball with the exact amount of force and to give the ball the exact angle that is needed every time a shot is taken... ...the more energy is lost and the less the ball bounces back. The less denting that occurs, the more energy is kept and the higher the ball bounces back. Physics can be used to explain a lot of things. In this paper I described some basic concepts in physics that are relevant to basketball, particularly the three main parts of basketball, shooting, dribbling and passing. So the next time you are out shooting some hoops just think of all the physics that are being applied and you could be one step away from being a physicist, and have fun.

Racism from past to present

Racism is the belief that a race is superior to all other races and has the right to manage all other races. This term emphasizes the superiority In terms of the biological differences, such as color and gender. In the history, although racism was used to organize daily life in clans, with Greeks it gained its negative meaning. With the Renaissance and the Reform, Europeans discovered new nations and places. However, according to Europeans' understanding, these new people can only be slaves. Therefore, racism has actually begun. The first modern fascist leader ofEuropean, Mussolini had a strong belief about being racist. He did not give right to live to any thought but his thought. He killed many people. In Dalton, Hitler was another fascist leader who murdered millions of people because of their races. Thus racism has become known. Basically, as both Connelly (2004, p. 72) and Shah (2010, Para. L) say that people have tendency to be superior to others. Shah adds that racism has been used as weapons. As it was in the past, racism still exists all over the world. Proponents of the idea that racism still exist claim that due to laws, racism Anton exist.They also mention that according to the universal Declaration of Human Rights, all humans are equal. They may have a point but laws cannot prevent racism and racists. Laws are valid only racists are caught. In the united States for example, although punishment is serious, racism exists in the aspect of black and white. Blacks have separate neighborhood from whites, they do not like whites' thoughts or they do not have a white person in their environment. The reason for this is that in the past, whites saw and used blacks as slaves. In today, there is not a comprehension about Ewing slave but whites still humiliates blacks.This causes white racism. Moreover, racists do not have to show how they believe or they do not have to discriminate. They can only have thoughts of being racist and laws cannot catch or prevent t his kind of thoughts. The reason why racism still exists is the human nature regarding inferior and superior. First, in the aspect of superior, they are naturally arrogant people. This class thinks that they are superior to everyone in everything. Therefore, they humiliate other races. Due to physical characteristic of other races, they make a trooper for specific races and they become prejudice.Europeans prejudice about Arabians can be given as an example. They think that Arabians are dirty and they smell bad. This situation causes racism today. Moreover, superior race thinks that they have the right to determine other races' rights, such as how they think, where they can live or whether they can live or not. Hitler for example, had a great power to take lives of Jewish people. Today, similarly to Hitter's reason, there is a problem called smuggling of people. Generally, people who are smuggled are from either Africa or Middle East, they were never European.Smuggling soul exists be cause superior races think that they can employ them illegally. Second, in aspect of inferior people, there is a fear of superior ones. Being a criminal race produces that kind of fear. As Russell (1 998, p. 124) mentions Willow's thesis about black crime causes white fear, white racism caused by Black and Latino men. If they did not have this high rate of crime, there would not be white fear. Furthermore, another kind of fear from superior happens as action and reaction. If Europeans are racists to Arabians, then stay away from Europeans because they feel inferior.Another reason why racism still exists is what happened in history. They may have not happened because of racism but they trigger racism today. First, events about economy have really changed the world. After the Reform and the Renaissance, colonialism came into the world. India was one of the countries colonized by England. As Marvin states, â€Å"At any rate, no serious effort has ever been made to colonize the country , and the English who go to India think only of acquiring the largest amount of money in the shortest possible time, and returning home to enjoy it in their beloved fatherland† (2006, p. ). Thus, today racism still exists between India and England. Second, political history caused racism today as well. In the history, states struggled for independence. In Ottoman Empire, for example, there were many nations who live peacefully. However, when the Ottoman Empire started to fall down, Armenian rebelled. They wanted to have their own country in the soil that they live in but it belonged to the Ottoman Empire. Because of this situation, Ottomans and Armenian had disagreement. Then that disagreement cause today the so-called Armenian genocide. Now, Turkey andArmenian are prejudiced to each other because of what happened in history. Bad treatment to Armenian or reverse produces racism in both countries. All in all, racism still exists in our world. People should remember that as worl d and politic changes, terms meanings will either be change or be broaden. While the term racism was used for people who support his race, then it is used for humiliation. In our world, it almost lost its meaning because today anything can be racism, such as prejudice or difference of thoughts among nations. Racism is not biological differences anymore.

Free Essays on The Life Of Music Of Sarah Vaughan

Instruments have always been essential to jazz music but one great vocalist one knew how to captivate listeners in such a way that her voice was all that they heard. Sarah Lois Vaughan was born March 27, 1924 in Newark, New Jersey to a family of a non- famous musical background. Vaughan started early with her musical interest by playing piano, sang in the church choir playing the organ by age 12 and attending Arts High School. In 1942, at the age of 18, Sarah and a friend decided to enter an amateur contest in the now famous Apollo Theater in Harlem, New York. Sarah won the prize of ten dollars and a weeks performance at the theater for singing †Body and Soul† but that is not all she won that day. Billy Eckstine, who was at that time a part of Earl â€Å"FATHA† Hines Big Band invited her to be second pianist and a vocalist in this band. By 1944 Hines had decided to form his own band which included Vaughan along with greats like Miles Davis, Dizzy Gillespie, and Charlie Parker and was known for it’s be-bop style music. During this time she made her first recordings and did a duet with Gillespie called â€Å"Lover Man†. Sarah had later made the decision to go solo. â€Å"Sassy† and â€Å"The Divine One† were two of nicknames given to Vaughan and by 1947 she had married trumpeter George Treadwell. In ’49 she had signed with Columbia Records with a five- year contract. It is during this time where it is said Vaughan did most of her â€Å"sweet† or â€Å"commercial† work.

Comparison of Two People in the Same Profession Article - 1

Comparison of Two People in the Same Profession - Article Example To be able to do this, this paper settles on two teachers.     Robots can be exact duplicates whereas, in human beings, all people are unique. It is because of this reason that no single firm can leave the role in making decision role to robots. Moreover, another question can be raised from this fact is: Why are there people to make decisions? The fact of two teachers being on the same level and under the same management and governance does not mean the same level of intellectuality and ability to make decisions. The degree to how fast an individual can make a right decision varies from one person to the other depending on a number of factors. Some of these factors range from inborn capability, experiences in life, age, gender, family backgrounds to the level of education. A crisis of the same magnitude presented to two teachers can be mandated to have different responses if the crisis is not numerical. In the same manner, response to decisions made by the management can vary no matter the fact that they can be trained to respond to such. These differences, however, do not despite the fact that it is possible to make a similar decision or give similar reasons for a crisis (Yengoyan 14). These two teachers can be agitated by different occurrences in a classroom, for instance, one can be so furious with a student who does not hand in his or her assignment in time while the other can get so angry with one who is late for classes. None of the two makes one a lesser teacher or vice-versa, but the situation acts independently to bring out the diversity of people although in the same field. At this juncture, it is good to state that either teacher or both could be in the profession out of lack, passion, family reasons or even religious reasons. A teacher in the profession out of passion is quite different from that is in it because of any other reason. To start with the former will have an inner driving force to work while the latter will work out of external forc es. Amazingly, both perform to the expectation of the organization. The diversity of reasons unto why one is a teacher is by its own an explanation for a myriad of responses in the teaching field. It is because of the diversity of these reasons that explain the difference between teachers when faced with a challenge. For example, when a teacher reprimands a student out of misconduct and the student takes him or her in a court of law. No matter the sentence of the court the fact of being to a court of the law may either make one feel humiliated or a rise in self-esteem. The capability that one can be allured into the wind of a riot or a strikeout of poor work conditions can also have its basis on the same reasons. The reasons for the dynamic behavior of teachers also have an association with the reasons for being in the profession.

The researcher will make use of the qualitative-descriptive method of research.

The collected data will be computed statistically for mean, median, mode, percentile rank, and relative frequency. Chapter 1 INTRODUCTION Conventionally, education of a country's citizens is left to those people who have gained... This study primarily focused on the information given by the private schools in Saudi Arabia. The respondents of the study are the expatriate teachers and students. The Local teachers and students were not included in this study. The researcher went over a number of books, journals, and online resources. The studies which were found relevant to the present day research are mentioned below. This report makes a conclusion that the Saudi Arabian government realized the need for its nationals to be effective conversationalist with the world. This was driven by its extensive oil and aggregates products export to other countries. For example, ARAMCO in 1968 created a verbal communication program for foreign dialect schooling. This was geared towards outputs or people that are conversant with different dialects. Having gained the necessary conversation tools, these people were posted and employed by the Saudi government to many sensitive areas of the business entity. On the other hand, because of the oil export business of Saudi Arabia, some nationals have to go to foreign countries to close deals and get related transactions done. All these supposedly require the proficiency in speaking and reading foreign language as the Saudi nationals can not always rely on language translators. Moreover, Mecca in Saudi Arabia is the Islamic congregation center for pilgrimage. Thus, Musli ms from foreign countries regularly come for the religious rites.
