Pregnancy as it pertains to MRI - Essay Example These particles produce signals due to Radio waves that are collected by a receiver within the scanner. These signals are characterized with the use of varying magnetic field and are further processed by a computer in order to create ultra sharp images of tissues in the form of "slices" that can be viewed in any plane and from any direction. The key advantage of MRI is that it causes no pain and the responsible magnetic fields cause no damage of any kind to human tissues. The MR scanner used may generate considerably loud tapping or knocking noises during the process but it can be prevented using earplugs. A patient can easily communicate with the technologist or radiologist at any instant with the use of an intercom. The magnetic field generated in the MR system is quite powerful and will attract Ferro-magnetic objects and can cause them to move suddenly and with a considerable force. Thus, there can be a risk to the person in the flight path of the object. Due to this reason, great care is taken and ferromagnetic objects like screwdrivers and oxygen tanks are not allowed into the MR system area. A patient is asked to remove all kind of metallic belongings like watches and jewelry before going for an MRI. The magnetic field of the MR system is of considerable magnitude and can pull on any iron-containing object in the body like medication pumps or aneurysm clips. Every MRI facility has a strict protocol that ensures that the MRI technologist and radiologist know about the presence of all metallic implants and materials so that special precautions can be taken. Sometimes, even the exam may have to be canceled. In case a bullet or other metallic fragments are present in the body, there is a risk that it could change position leading to an injury. A metallic implant can not only distort the MR images but also make it difficult for the MRI system to tune to your body. It is not possible to avoid it but allowance can be made while interpreting the images only if the radiologist is aware of their presence. Some MRI examines a gadolinium that may be injected into a vein in order to help the interpretation. a gadolinium is a contrast agent that does not contain iodine like those materials which are commonly used in x-ray process and hence rarely causes any problem or allergic reaction. Preparation for MRI The patient is asked to wear a special gown during the MRI study. The person (generally a friend or relative) accompanying you will be asked questions regarding the presence of implants and will be instructed to remove all metal objects from pockets and hair even before entering the room. A screening form is filled to ensure that the patient may safely enter

Raw by Scott Monk and Hero of War by Rise Against Extended response Essay Example for Free

Raw by Scott Monk and Hero of War by Rise Against Extended response Essay ‘Institutions can change one for better or worse’ this quote is proven in the novel ‘raw’ by Scott Monk and ‘Hero of War’ by Rise Against. Through the contrasting ideas of rebellion and conformity, the responders are able to see how institutions can manipulate one and have a negative or positive impact. In ‘Raw’ by Scott Monk, Brett uses rebellion to escape from his fears and then be liberated from it; he does this as he believes it is the only way to freedom. When Brett first gets to the farm he is given trust and responsibility straight away which he is not used to as he has never been automatically trusted before. Brett is unaware of how to react to this, as he has only ever experienced negative forms of authority beforehand. Brett believes that Sam is naà ¯ve and stupid for giving Brett and the other boys at the farm trust. Sam believes in giving everyone second chances and that if people want to change then it is up to them. The institution can change one for better or worse but it’s up to the persona to allow the change, so if they refuse the tools the institution provides them with, then they will stay the same. The farm as an institution has a positive impact on Brett, because once he starts taking responsibility for his actions then he changes. â€Å"†¦He didn’t want to be here. It was a waste of time†¦Ã¢â‚¬  through the use of third person narration the responders are able to see that Brett’s attitude towards the institution as a whole is that, he believes that this institution is a waste of his time as he believes it isn’t going to help him. Later on in the novel Brett comes to realisation after Josh opens up to him, Brett realises that he shouldn’t blame his actions on everyone else, and that he should take responsibility and live up to the consequences. The responders are able to see how much Brett has changed in the end of the novel when Brett admit s that it was his fault that they broke up. â€Å"†¦I’m the one to blame!† The exclamation mark is used to emphasise that he is taking responsibility for his actions, and for once isn’t blaming it on her. Because of the tools that Sam has given Brett he now knows that rebellion is not always the viable option. Thus the institution has changed Brett for the better, as he now he takes responsibility for his choices and doesn’t blame everyone else. In contrast, the persona in ‘Hero of War’ By Rise Against, changes for the worst as a result of this institution. Throughout the film clip it shows flash backs of what he was like before he had joined the army,  which was happy and he had a good self-image. Then throughout the clip we are shown him being in a green room, where he is glowing and there is black surrounding him, as the responders we can see the emotional damage which the persona has been through. â€Å"†¦I told them to stop/But then I joined in†¦Ã¢â‚¬  This complete juxtaposition shows the audience how he is forced to conform and adhere to the institution. The effect of this is that the responders can see that even though the persona knows what h e is doing is wrong, he is forced to conform to the army. In the end of the video we are shown the persona walking the streets of America, painted in white with red glowing hands. This symbolises the guilt which he feels for conforming and taking the innocent lives. The persona no longer fits in to society’s mould. This is ironic as there is still a high camera angle on him showing that he has power, even though he doesn’t fit in. Thus this institution has changed the persona for the worst as he now has a sense of guilt within himself and doesn’t fit in to his home country which is America ‘the only flag I trust’ Ultimately through the study of Raw by Scott Monk and Hero of War by Rise Against, it is shown that institutions can have either a detrimental or beneficial impact on products of an institution. This is shown through the contrasting ideas of Rebellion and Conformity.

Values in Conflict Essay -- essays papers

Values in Conflict VALUES IN CONFLICT Introduction Each day as young people attend school they are bombarded with various moral messages. These messages come in many forms. These differing forms may be categorized in either of two different areas, moral instruction or moral practice (Jackson, Boostrom, and Hansen, 1993). Moral instruction refers to both formal and informal methods. Formal instruction as part of the classroom curriculum is directed and intentional. Sometimes formal moral instruction is not quite so obvious however. Rituals and ceremonies such as pep rallies, graduations, and various assemblies may all be categorized as formal moral instruction. Visual displays with moral content are also considered as formal instruction, although they are of a more passive approach. One can not walk the hallways of a typical middle school without seeing numerous examples of posters and signs which attempt to convey some sort of moral message. Perhaps the most subtle and least recognizable form of moral instruction is the interjection of moral commentary within an ongoing activity. Public recognition for doing exceptional work is just one example of such commentary. Moral practice methods may also be either formal or informal. The rules and regulations within the school and classroom would be considered formal forms of moral practice. A more informal method of moral practice would be the expressive morality within the classroom. Expressive morality may be conveyed either intentionally or unintentionally. Everything a teacher does, from facial expression and body language to expressing personal beliefs, can have an effect of influencing the values of an adolescent. Hence teachers should be extremely aware of this possibility. A Gallup (1980) public survey of attitudes towards schools showed that 79% of the respondents were in favor of some form of instruction which would concentrate on morals and the development of moral behaviors. Along with academic competence, character development is the most desired goal of educators (Wynne and Wahlberg, 1985). Many states actually mandate some form of character education by law. In Nebraska, state statutes 79-214 and 79-215 specifically outline this. Despite this apparent agreement between the public and educators, as well as its legitimacy under law, the teaching of moral beha... ...irely. References Jackson, P., Boostrom, R., and Hansen, D.

Stereotypes and Stereotyping in A Tale of Two Cities Essay example --

Stereotypes in A Tale of Two Cities      Ã‚  Ã‚  Ã‚   Charles Dickens stereotypes many of his Characters in A Tale of Two Cities. Among these stereotyped characters are The Marquis D' Evremond, Lucy, and Miss Pross. These particular stereotypes were probably intentional, for Dicken's was not a skilled writer.        Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Marquis d' Evremond was probably intentionally stereotyped. His character is basically used to represent the French Military of the time, so he was as cruel, ignorant, and pompous as the French citizens were at that time. His actions when his carriage runs over a child clearly show Dickens's motive: to portray the French Military of the era as kind and generous citizens, and to sort of justify the French Revolution. His dialogue with Miss Pross early in the story also shows his contempt for the proletariat; furthering his role as the stereotype of the Military. Just as he symbolizes the blood spilled in the revolution, his birth symbolizes the fall of the Monarchy to come.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Lucy'...

The Nature of Abigail’s Villainy in The Crucible

A dynamic antagonist, Abigail Williams from Arthur Miller’s The Crucible is a great example of how a character can be molded by personal desires and a work’s setting to become a villain. Seemingly innocent, orphaned adolescent Abigail ultimately causes hysteria in the town of Salem from her frivolity and selfishness. The reasoning and origins of Abigail’s malice demonstrate the setting’s influence on the inhabitants of Salem during the 1962 witch trials. Abigail is introduced as Parris’ niece. At the beginning of the play, Arthur Miller provides what might be an explanation to the start of Abigail’s needy nature as she relays the story of how she became orphaned to her friends. Abigail explains that she witnessed her parents being killed by indians when she was a child. This harsh past and lack of a good authority male figure (Parris is a character that is extremely paranoid and obsessed with his reputation; definitely not fatherly or nurturing) explains her initial attraction to John Proctor; her older, married, employer before the play begins. Abigail’s affair with Proctor is the fundamental start of the witch trials. Had she never had the affair, she’d never have fallen for Proctor, therefore she wouldn’t want to kill his wife in order to have him back. The Puritan way of thinking and strict religious system in Salem paved the way for a villain to arise. Abigail’s villainy is significant because it helps the reader become familiarized with the environment of Salem Massachusetts, the Christian religion it thrived off of, and how these combined ultimately caused the witch trials. The people who practiced this intense Christianity had no spiritual method to relinquish guilt for their sins. In turn, this led to the people of Salem having to find their own outlets for their guilt. Along with the stress of guilt, the individuals of Salem have to worry about the constant need to make themselves adequate for the community. Reputation is extremely important, and being associated with anti-christ figures and ideas is completely unacceptable. These stresses combined raise the perfect type of people for Abigail to use to aid her in her plan to rid of Elizabeth. After practicing witch craft with her, Abigail’s friends feel guilty for the sin. Abigail’s failure to feel guilt or this (or any of other sin she commits throughout the play) is what attains her success is causing havoc in Salem. After being found out for their anti-Christian activities in the woods, Abigail begins accusing other random people in the community of witchcraft. The other girls follow suit, shuffling their guilt to someone else to feel self assurance. By accusing other people the girls felt they had retrieved innocence. In a sense Abigail was able to use her friends without them noticing. Through her manipulation shows malevolence. Of course, Abigail didn’t mean to cause so much conflict. She only wanted one person dead; Elizabeth. Had she not began accusing other people of witch craft to save her name, the problem wouldn’t have blown up to epic proportions. This doesn’t make her any less of a villain, however. Many of the townspeople were hanged because of her selfishness. Her naivety and fervent want for Proctor blinded her from consequences. Covering up herself snowballed to her friends and then out into the community. This is particularly interesting because in any other setting the word of these girls wouldn’t even be considered let alone used as solid judgement in court. Abigail’s success in causing death to innocents in the community, despite her age and insignificant role in the community, further exemplifies the atmosphere of the Puritan religion. After analyzing Abigail’s character one can learn much about the behavior of other people as well. Everyone has desires that they wish to obtain. Some obstacles must be overcome in order to achieve these. Due to Abigail’s villainy conceit many people suffered. Not only were lives lost, but she never found the peace she wished for with Proctor. It’s important to realize that there are consequences for neglecting the well being of others for self gain.

Book Report Inna Di Dancehall Essays

Book Report Inna Di Dancehall Essays Book Report Inna Di Dancehall Essay Book Report Inna Di Dancehall Essay Hope, paid homage to the lower-class inner city people of Jamaica. She gave them a voice as she explored the issues about danceable as related to the Jamaican society. Hope discussed the historical setting and definition of danceable, sex and gender, violence and identity in the danceable. The author used this forum to bring to life the perceived unknown truths about the danceable culture in Jamaica. Throughout the book, the theme of rudeness was explored. Hope linked rudeness to Jamaican culture and in essence showed how rudeness is a part of Caribbean civilization. Rudeness can be seen as vulgar behavior or otherwise known as slackness. In the Caribbean, slackness, refers to violence, promiscuity and anti-homosexual sentiments which are similar to the culture of Jamaica. Is Jamaican rudeness an excuse for culture or is it Just rudeness? To answer this question, one needs to delve into the history of Jamaican society and understand how rudeness may or may not relate to culture. As well as, how the popular music, danceable, may play a part in developing rudeness as a component of culture. In the book, Nina did Danceable, the author, Hope, listed the various factors which helped the formation of the popular form of music culture. Such factors were the fall-out of Jamaican experiment with structural adjustment; the rise of free market capitalism; increasing arbitration; rising political violence; a growing ideological convergence between the Peoples National Party (PAN) and the Jamaica Labor Party LOP); the explosion of Jamaican informal economy and ongoing transformations in the class/ status hierarchy, particularly among the middle strata (1). Some of these factors created tension in society and through music, the people in society were able to release this built up frustration. According to Hope danceable culture is a space for the cultural creation and dissemination of symbols and ideologies that reflect and legitimate the lived realities of its adherents, particularly those from the inner cities of Jamaica (27). Danceable enabled the society to openly voice their concerns and highlight the struggles of everyday life. As such, one can say that Jamaican rudeness is an excuse for culture. If danceable music reflects the everyday life of the lower class society, which is gun violence, promiscuity and hardships of the masses, elements of rudeness, and danceable music is part of the Jamaican culture, hence, rudeness is Jamaican culture. On the other hand, Jamaican rudeness has a negative connotation as it deals with negative activities in society. One should not sensationalist illegal activities such as gun violence and discrimination against homosexuals. The authors aim was to shed light on the different aspects of danceable and show how danceable music fleets the lower-class society in Jamaica. However, in doing so, the author provided an excuse for the high crime rate, gun violence, debase behavior of women and discrimination against homosexuals. The author used this forum to explicitly say that this rudeness is a part of culture and should be accepted and therefore sensationalists a topic that has no merit. This behavior should not be accepted and measures should be put in place to curb illegal activities. Should be able to make a decision on what type of literature to read or be exposed to. However, based on the circumstances, the purpose of studying Caribbean Civilization is to understand the Caribbean society and one way of doing this is reading different literatures from the Caribbean. Nina did Danceable exposed the Caribbean and the wider world to the danceable culture of Jamaica. Its important as a Caribbean person to know and understand the different cultures of the Caribbean. This book, gave a real representation of the lower-class society of Jamaica through danceable. However, it didnt paint the full picture of the Jamaican culture. It pulled out the negative aspect of Jamaican culture and glorified it. Should one be exposed to the glorification of illegal activities? No. However, one should be made aware of all aspects of ones culture whether be it negative or positive. Reading literatures of other cultures broadens ones perspective on the ways of life of many people. It enables one to have a holistic view on life and treat others from different backgrounds with respect. According to the Peace Corps Cross-cultural Workbook, By knowing peoples values and beliefs, you can come to expect and predict their behavior Moreover, once you accept that people behave the way they do for a reason You can go beyond simply reacting to that behavior and figure out how to work with it (5). As a result, using Nina did Danceable in Caribbean Civilization has meaning as it enhances the course by cultural differentiation. Its a great book as it would enable discussions on class/ color/ status hierarchy in society. Hope clearly discussed the differences in social classes in Jamaica. This was a main topic in this course as the Caribbean continues with this social structure from slavery. Trinidad and Tobago can definitely benefit from the propagation of this type of reading. Our society can learn about the danceable culture, understand how it came about and the true meaning behind danceable. This type of reading would allow our society to be able to differentiate our culture from Jamaica. It would also encourage patriotism, as local writers would be encouraged to write about our culture for the world to read. However, this reading may as well not benefit society. This type of reading may encourage similar types of behavior to be patterned in our society. Youths in society may read this book and may not capture the real essence of the book. They may try to emulate their danceable idols and adopt behaviors and attitudes that are not accepted in society. However, Hope formatted Nina did Danceable cleverly as it was easy to read. In each chapter there were sub-sections which allowed the reader to understand each aspect of the danceable culture. The headings played a key role as it made it clear as to what was going to be discussed. The pictures used in the book in some instances were quite vulgar and degraded women but captured the idea that was being put cross. It didnt make the book more appealing; ironically, it made the book less appealing which may not have been the authors purpose. In conclusion, Nina did Danceable would not have been a first choice book for reading; however, it served the purpose for this course. It highlighted aspects of Jamaican culture, danceable and showed its relevance to Caribbean society as it dealt with some Caribbean issues such as class/ race/ status hierarchy. Hope, Donna P.

Write a Case Study - its easy!

Write a Case Study - its easy! How to write Case Study correctly Review of a problem or situation in real life, in which the author analyzes the main problems. In this case, all facts should refer to scientific literature or research results on this topic. In the end, you draw conclusions about why the situation arose, and how to find the way out. The definition of a case study is the following: it is a method of applying theoretical knowledge to real life situations that you can face at any time. Such a study gives the student much useful. He: 1. Trains in using theoretical knowledge in practice; 2. Learns to analyze problems in a real life situation; 3. Draws conclusions about how the knowledge gained in the course of academic research will help him to properly respond to the situation. There are many types of case studies: 1. Illustrative; 2. Exploratory; 3. Critical instance; 4. Program implementation; 5. Program effects; 6. Prospective; 7. Cumulative; 8. Narrative; 9. Medical; 10. Embedded. Let us consider in more detail the four most popular types of the case study. Illustrative study. This is a description of one or two cases from real life. They allow the reader to get acquainted with the concept and give a general idea of the solution of the problem in a particular case. Cumulative case study. Several cases are considered here. The main purpose of the author is to draw up generalized conclusions. Narrative studies. The situation is seen as an artistic story and is written by a third person. There are characters and a plot. Critical Instance. One or more cases are used here. Then an assumption is made, which is criticized by the author of the study. This kind of case study is very popular for the analysis of situations of causes and effects. Structure of writing a response to a particular case Before you start writing a response to a case study, read it carefully first. It's best if you do it two or three times. In doing so, pay special attention to the main problems and a group of people who are interested in solving the situation. The answer to the case study has its own structure. It includes four parts: 1. Introduction; 2. Description; 3. Discussion; 4. Conclusions and recommendations. Now consider each part in more detail. Introduction Your goal is to briefly describe the life situation and describe the problem to be solved. Description Create a more detailed description of the problem. Proceed from the fact that the reader does not have any knowledge at all in this field. This means that you need to give exhaustive information about the situation before proceeding to its discussion. Discussion This part of your essay is a list of pre-prepared questions, as well as answers to them. The answers should be based on information from the scientific literature. The "Discussion" block can include such questions (and subsequent answers to them): 1. What is the problem and what are the consequences for all involved persons?; 2. How can information in the scientific literature help in solving this problem?; 3. What are the ways to solve the problem? 4. How can you evaluate ideas and solutions to this problem for a specific case? When you give arguments in favor of solving the problem, refer to specific sources of literature. Also, you can use the quotes of scientists entirely. Every answer must necessarily have a reference to academic work. Conclusions and recommendations Now you need to write a conclusion. Here you describe the conclusions you came to, and also give recommendations for solving this problem. You should make your own recommendations that reflect your point of view. The correct approach to writing the answer In order to correctly approach the writing of a response to a case study, first answer a number of questions: 1. Is the research topic really atypical and requiring detailed analysis? 2. Is the case really important? 3. Is there an opposite point of view on the solution to this problem? If so, what arguments can you give in favor of your opinion?
