The Bullwhip Effect - Assignment Example The Bullwhip Effect is of great concern because it can lead to low profits, increased costs, poor use of transport and storage facilities, inefficiency in the use of limited resources and even crisis in placing orders. All these reasons explain why this is a great area of interest (Bhattacharya & Bandyopadhyay, 2011). It is also a significant area that should be studied in order to increase efficiency in how enterprises carry their day to day activities. I am also interested in this topic because I would like to contribute to its solution. Moreover, an aspect of academic curiosity sparked my interest in the topic. The research conducted shows a number of similarities with what I learned in the Module. For instance, the definition of the Bullwhip Effect tends to be the same. Even the environment and circumstances in which it occurs is very similar. For both, the phenomenon occurs in a supply chain where there are members placing orders to each subsequent member in the upstream. In both, the fact that Bullwhip Effect results in an increased or exaggerated variability in the upstream end more than the downstream is recognized. The Bullwhip effect arises as a result of various factors. Some of the causes are rationing and shortage gaming, price fluctuations, demand forecast, updating and order batching. These causes coupled up with the manager’s decisions, most of which are rational, lead to the Bullwhip Effect. Forecasts made based on information from the member down the stream lead to amplification of demand. Dependence on these downstream pieces of information to plan for inventory ofte n misleads. As such, many upstream members end up having a greater variability of demand (Lee et al., 2014). Another cause is the frequent change in prices in the market. Sometimes the manufacturers reduce the prices of their products. This makes more suppliers in the downstream end to do ‘forward buying’. This is in a

The Analysis of Unknown Citizen Essay Example for Free

The Analysis of Unknown Citizen Essay The Unknown Citizen seems to describe story about the Unknown Soldier, a term used to recognize people whose bodies are found after a battle but cannot be identified. This poem begins by the word â€Å"He was found by the Bureau of Statistics† It is describing a person referred to as, simply, He. We take this to be The Unknown Citizen, which makes sense because his name isn’t known, the ordinary average citizen in the modern industrialized urban society who has no individuality and identity. The concept of this poem suggests that the lives of many normal people are so conventional and uneventful that they might as well be unknown or anonymous. There is a message that the writer wants to be told to the readers, it is â€Å" you don’t want to end up like the Unknown Citizen†. In the final of the poem, the writer asks two questions, they are â€Å"Was he free? Was he happy?†. By asking these questions, the poet is drawing our attention to the question of freedom and happiness. It’s interesting that these two questions are referred to in the singular, as the question, as if being free and being happy were the same thing. The Unknown Citizen uses the old-fashion style, eventhough it is written in modern era. The writer, Auden, is known as a master of of the rhyming couplet (AA, BB), the simplest rhyme scheme in English. Auden is considered a modernist writer, but his work is unlike that of any other poet of the past century. The Unknown Citizen deserves a central place in our nation’s capital, considering all his huge accomplishments like having five kids. It will be right down the street from the Bureau of Statistics, a huge, drab marble building.

Bill Gates and Oprah Winfrey | Leadership

Bill Gates and Oprah Winfrey | Leadership This report presents a review of leadership theories in brief and the contrast and similarity between Bill Gates and Oprah Winfrey Leadership style; who are two of the well known people in the world. The report begins with an introduction about the two well known faces, Opera Winfrey and Bill Gates who are consider as the successful leaders in the world. The next section would be the biography of Opera and Bill gates in brief. The following section gives a brief review of leadership theories which have been applied in different organizations during these years. Bill Gates and Oprah Winfrey Leadership Qualities which are the main idea of this paper is discussed in the current section and the aim of this section is the better understanding of the importance of leadership quality in a successful business. The next section discuss the similarity and contrast between Bill Gates leadership quality and the leadership quality of Opera Winfrey in terms of leadership theories in general In the current section , my own opinion about Bill Gates and Oprah Winfrey Leadership style would be explained The report conclusion is about he Introduction Welcome to this report which was a glimpse of the Management and Leadership theories and how famous people such as Opera Winfrey and Bill Gates applied them to achieve their success. It draws together a range of materials detailing approaches to leadership and leadership theories. The ability to inspire people to reach great performance and success is a skill that leaders need. Passion, purpose, listening and meaning help make a leader inspirational. The ability to communicate that passion, purpose and meaning to others helps establish the motivating culture of your organization. These points will tell you how to enable inspiration and motivation in the people you lead. In the list of the worlds ranking mega-leaders, there are few women. This is undoubtedly not for any lack of talent or leadership ability among women, but more likely because the step between being a good leader and being a world-renowned mega-leader is quite large, and few women or men, for that matter have been able to pull together all of the abilities and resources necessary to make it happen. In Oprah Winfreys case, however, mega-leadership was achievable, and she has not only achieved it but keeps increasing her leadership base. On the other hand Bill Gates is one of the most successful e ntrepreneurs of the world. He is able to run a successful and a profitable entrepreneurship for many years and even today, we cannot survive in this competitive world without it. Vision and dedication are the key factors of being a successful entrepreneur and these skills were present in Bill Gates from the beginning. Bill Gates Bill Gates was born on October 28, 1955 in a family having rich business, political and community service background. Bill strongly believes in hard work. He believes that if you are intelligent and know how to apply your intelligence, you can achieve anything. From childhood Bill was ambitious, intelligent and competitive. These qualities helped him to attain top position in the profession he chose. In school, he had an excellent record in mathematics and science. Still he was getting very bored in school. Bills parents came to know their sons intelligence and decided to enroll him in a private school, known for its intense academic environment. Bill Gates and his friends were very much interested in computer and formed Programmers Group in late 1968. In the next year, they got their first opportunity in Information Sciences Inc, which they were selected as programmers. ISI (Information Sciences Inc.) agreed to give them royalties whenever it made money from any of the groups progra m. As a result of the business deal signed with Information Sciences Inc., the group also became a legal business. Bill Gates and his close friend Allen started new company of their own, Traf-O-Data. They developed a small computer to measure traffic flow. From this project they earned around $20,000. The era of Traf-O-Data came to an end when Gates left the college. In 1973, he left home for Harvard University. He took the standard freshman courses with the exception of signing up for one of Harvards toughest mathematics courses. He did well over there, but he couldnt find it interesting too. At the end of Bills first year, his best friend Allen, came close to him so that they could follow some of their ideas. That summer they got job in Honeywell. Allen kept on pushing Bill for opening a new software company. Within a year, Bill Gates dropped out from Harvard. Then he formed Microsoft. Microsofts vision is A computer on every desk and Microsoft software on every computer. Bill is a visionary person and works very hard to achieve his vision. ( Ravi Kumar Paluri) Oprah Winfrey Born in Kosciusko, Mississippi, Oprah Winfrey was reared by her grandmother on a farm where she began her broadcasting career by learning to read aloud and perform recitation at the age of three. After suffering abuse and molestation, at the age of 13, she was sent to Nashville to live under her fathers strict discipline As strict as he was, says Oprah, he had some concerns about me making the best of my life, and would not accept anything less than what he thought was my best. Oprah Winfreys broadcasting career began at age 17, when she was hired by WVOL radio in Nashville, and two years later signed on with WTVF-TV in Nashville as a reporter/anchor. She attended Tennessee State University, where she majored in Speech Communications and Performing Arts. In 1976, she moved to Baltimore to join WJZ-TV news as a co-anchor, and in 1978 discovered her talent for hosting talk shows when she became co-host of WJZ-TVs People Are Talking, while continuing to serve as anchor and news reporter. In January 1984, she came to Chicago to host WLS-TVs AM Chicago, a faltering local talk show. In less than a year, she turned AM Chicago into the hottest show in town. The format was soon expanded to one hour, and in September 1985 it was renamed The Oprah Winfrey Show. Seen nationally since September 8, 1986, The Oprah Winfrey Show became the number one talk show in national syndication in less than a year. In June 1987, in its first year of eligibility, The Oprah Winfrey Show received three Daytime Emmy Awards in the categories of Outstanding Host, Outstanding Talk/Service Program and Outstanding Direction. In June 1988, The Oprah Winfrey Show received its second consecutive Daytime Emmy Award as Outstanding Talk/Service Program, and she herself received the International Radio and Television Societys Broadcaster of the Year Award. She was the youngest person and only the fifth woman ever to receive the honor in IRTSs 25-year history. Winfreys business and personal interests are wide ranging and she has managed to accomplish success in several areas. Apart from being a successful Talk show host she is also a producer, successful actress, Founder of the successful O, the Oprah Magazine, co founder of Oxygen Media, and a generous Philanthropist. Her entrepreneurial spirit and desire to change society for the better have brought her and her numerous companies many awards and achievements. Oprah Winfrey was named one of the 100 Most Influential People of the 20th Century by Time magazine, and in 1998 received a Lifetime Achievement Award from the National Academy of Television Arts and Sciences. (Opera Winfrey) REVIEW OF LEADERSHIP THEORY A review of the leadership literature reveals a developing series of schools of thought from Great Man and Trait theories to Transformational leadership (see table). Later theories begin to consider the role of followers and the related nature of leadership, whilst early theories tend to focus upon the characteristics and behaviors of successful leaders. Great Man Theories Based on the belief that leaders are exceptional people, born with inborn qualities, destined to lead. The use of the term man was intentional since until the latter part of the twentieth century leadership was thought of as a concept, which is primarily male, military and Western. This led to the next school of Trait Theories Trait Theories The lists of traits or qualities associated with leadership exist in plenty and continue to be produced. They draw on virtually all the adjectives in the dictionary which describe some positive or worthy human attribute, from ambition to zest for life Behaviorist Theories These concentrate on what leaders actually do rather than on their qualities. Different patterns of behavior are observed and categorized as styles of leadership. This area has probably attracted most attention from practicing managers Situational Leadership This approach sees leadership as specific to the situation in which it is being exercised. For example, whilst some situations may require a domineering style, others may need a more participative approach. It also proposes that there may be differences in required leadership styles at different levels in the same organization Contingency Theory This is an improvement of the situational viewpoint and focuses on identifying the situational variables which best predict the most appropriate or effective leadership style to fit the particular circumstances Transactional Theory This approach emphasizes the importance of the relationship between leader and followers, focusing on the mutual benefits derived from a form of contract through which the leader delivers such things as rewards or recognition in return for the commitment or loyalty of the followers Transformational Theory The central concept here is change and the role of leadership in visualizing and implementing the transformation of organizational performance Bill Gates Leadership Qualities Bill Gates with her vision has a clear, vivid picture of where to go, as well as a firm find on what success looks like and how to achieve it. Jack Welch, former chairman and CEO of General Electric Co., said, Good business leaders create a vision, articulate the vision, passionately own the vision and relentlessly drive it to completion. Bill Gates communicates clearly and passionately and this is one of the most powerful points of this manager. Bill Gates has the discipline to work toward his vision single-mindedly, as well as to direct his manner and those of the team toward the goal. Bill Gates leadership is participative style because he involves his subordinate in decision making. He is a flexible person and he recognized his role was to be visionary of the company. When ever needed he bring professional manager for managing and well structure of the organization. Gates is a strong and energizing person his enthusiasm, hard working nature, judgment skills reflect his personality. His motivating power and involving his friends to working with him became the success of Microsoft. Integrity is the integration of outward actions and inner values (Bergmann, 1999). Bill Gates as a person of integrity is the same on the outside and on the inside. Such an individual can be trusted because he never veers from inner values, even when it might be expeditious to do so. Bill Gates has the trust of followers and therefore must display integrity. Dedication means spending whatever time or energy is necessary to accomplish the task at hand (Bergmann, 1999). Bill Gates inspires dedication by example, doing whatever it takes to complete the next step toward the vision. Magnanimity means giving credit where it is due (Bergmann, 1999). Bill Gates as a leader ensures that credit for successes is spread as widely as possible throughout the company. Conversely, Bill Gates takes personal responsibility for failures. This sort of reverse magnanimity helps other people feel good about them and draws the team closer together. Leaders with humility recognize that they are no better or worse than other members of the team. Bill Gates is not self-effacing but rather tries to elevate everyone.. Mahatma Gandhi is a role model for Indian leaders, and he pursued a follower-centric leadership role. Openness means being able to listen to new ideas, even if they do not conform to the usual way of thinking. Bill Gates is able to suspend judgment while listening to others ideas, as well as accept new ways of doing things that someone else thought of. Openness builds mutual respect and trust between leaders and followers, and it also keeps the team well supplied with new ideas that can further its vision. Creativity is the most important leadership quality of Bill Gates. Bill gates develop computer language new Altair 8080 pc which became the foundation of Microsoft. Bill continuously develops two other computer languages. When IBM develops their first pc and which need operating system to run the computer, Microsoft develops MS-DOS for IBM. Gates adopting the changes very fast that are his enthusiasm vision and hard working give him the success. Gates always recognized him as a visionary he always recognize professional management, he decentralize authority to make organization structure better. Fairness means dealing with others consistently and justly. Bill gates check all the facts and hear everyone out before passing judgment. He avoids leaping to conclusions based on incomplete evidence. When people feel they that are being treated fairly, they reward a leader with loyalty and dedication. Bill gates know how to use humor to energize followers. Humor is a form of power that provides some control over the work environment. One of the most important quality of Bill gates is that he is and supportive. Bill gates always take the blame for a loss, turnover, miss executed play, etc. If the problem wasnt his fault, he wont blame anyone else; he either blames himself, or dont say anything. Bill gates also know how to take charge. When the rest of the team seems confused, he will take control and guide the rest of the members. Bill gates know how to stay calm under pressure. While normal people may crack or feel flustered, he knows how to guide his team to victory and stay cool. He also has confidence in his team members, he has a good communication and, to let his team mates improve themselves. If a mistake is done, he will accept the mistake and take that mistake to improve the team. Oprah Winfrey Leadership Qualities Oprah Winfrey has an exemplary character. One of the important points for leaders is trustworthy to lead others whish she has it. She is enthusiastic about her work or cause and also about her role as leader (Blackler, 2003). It is a fact that people will respond more openly to a person like Oprah Winfrey that has passion and dedication. She has the ability to be able to be a source of inspiration, and be a motivator towards the required action or cause. Although, if we have a comparison between the responsibilities and positions of Oprah Winfrey and Bill Gates we can find many differences, she need to be seen to be part of the team working towards the goal same as Bill Gates. Result of researches shows that in order to lead and set direction a leader needs to appear confident as a person and in the leadership role and she is confident. She has the ability to function in an orderly and purposeful manner in situations of uncertainty. She is tolerant of ambiguity and remains calm, composed and steadfast to the main purpose (Blackler, 2003). Oprah Winfrey as well as keeping the main goal in focus is able to think analytically. Not only does a good leader view a situation as a whole, but is able to break it down into sub parts for closer inspection. She stand up for what is right, even in the face of popular disagreement. She also accepts blame when at fault. The most amazing thing is she has an inward desire that motivates her to excel; she also has the willing to act without orders and to offer well-considered recommendations for the improvement of the command. She is accountable, and that quality forms the cornerstone of leadership. She makes decisions, good or bad, and accepts the responsibility and consequences for those decisions. Compare between Leadership qualities of Gates and Winfrey Oprah Winfrey as a leader is more assertive and persuasive, has a stronger need to get things done and is more willing to take risks than Bill Gates. He remains stymied in the same occupational title and pay level for many years. He become too valuable in his positions in Microsoft .Bill Gates does not have any more strong will to make risk and put his self in dangerous situation. Oprah Winfrey was also found to be more empathetic and flexible, as well as stronger in interpersonal skills that bring the special ability for her to read situations accurately and take information in from all sides same as Bill Gates. Both of them as two of biggest leaders in the world are able to bring others around to their point of view, so that the people they are leading feel more understood, supported and valued. When we have a comparison between these two we can find that both of them have the ability to attract peoples attention and the great ability to digest input of the entire people of the world. Beside of that, they have Keeping people involved on the task at hand and understanding when to push and when not to. Leadership comes in many styles, shapes, and forms. Some people are leaders because they lead by example to better a group of people, and others are leaders because people learn from their decisions and business ideas. As a leader, Bill Gates believed that his managers should have their own personal authority. Indeed, each manager was expected to act like his own little CEO in his own modest right. He desired his managers to be responsible for his own influence on the stream of things and the tides of change. From here, we could tell them Gates also show some form of participative leadership, whereby Gates demand his managers to be creative and able to solve complex problems, and improving their quality. I personally prefer this style of leadership that Gates uses as it seems to be in the middle between not being engaged and over controlling, allowing the organization to be able to innovate and grow. Oprah Winfrey, communicate clearly and honestly to their followers, she use a combination of their personality, beliefs and capabilities to lead. Motivating followers to support and implement her ideas through change is an important part of the way that she uses to influence the peoples of different societies. She wishes inspire trust and confidence in her followers and with strategic thinking and trust building, support and empower her followers to be a catalyst for change. Conclusion As a conclusion, after a review of leadership theories in brief and the contrast and similarity between Bill Gates and Oprah Winfrey Leadership style; who are two of the well known people in the world we can find that there is not one standard, correct style for all leaders in all circumstances at all times and any group or individual behaves differently from each other. Each leader has to find differences and adapt according to the situation but at all they use same ideas in different ways for one target SUCCESS. Magnetic Resonance Imaging: Overview and Applications Magnetic Resonance Imaging: Overview and Applications How does Magnetic Resonance imaging work and how can it influence the future? An Introduction to Magnetic Resonance Imaging[1][2][3]: Magnetic resonance imaging (MRI) is used as an accurate form of disease detection which is usually used to confirm a patients condition, as well as a method of looking at trauma to the brain, examples of which could be bleeding and swelling. Alongside these uses MRI can be used to look at the soft tissues, as well as information on the structure of joints. Prior to the introduction, the only method for diagnosis for many of these problems were invasive methods such as surgery, and x-rays or CT-scans which were less accurate and ionizing, which could have a lasting effect upon the body. The use of MRI scans is only a recent phenomenon, with the first image on a person being produced as late as 1977, by Paul Lauterbur and Sir Peter Mansfield who received a shared Nobel prize for their work on this matter. Both scientists were looking at how nuclear magnetic resonance imaging could be used to look at solids and liquids, and both formed the theory behind it all, but it was Sir Peter Mansfield who developed the method used in MRI by firstly solving how to define a slice of a matter, and also how to produce images from multiple-pulse experiments. Although the work on producing images for biological specimens only came about as a result of the fact that it would be too hard to produce images of a solid. How does Magnetic Resonance Imaging work[4][5]? Magnetic resonance imaging involves a series of steps which are all explained below, in order to produce the final image that is used for diagnostics. Nuclear Spin The body’s mass is approximately 10% hydrogen, of which 70% is contained in water, and due to the fact that protons produce a large signal to a MRI scanner a more accurate image is produced, as they are in such large abundance in the body in the water. The hydrogen nuclei in the body spin about an axis, this is illustrated in figure 1.1. As a result of the spinning protons being charged, the spinning of a nuclei along an axis causes a small circulating electric current, which in turn causes a small magnetic field. If a collection of these nuclei were to be placed in a stronger external magnetic field (BØ), most of the nuclei will align their spin in the same direction as the external field. As you can see from figure 1.2 not all of the hydrogen nuclei are aligned with the direction of the magnetic field, and this is because both alignments are possible, but the one with the field is a lower energy state, whilst the protons against the field are at a higher energy state. The protons are continually oscillating back and forth between the two states, because there is a tendency for nuclei in a high energy state to return to a lower energy state by emitting some of its energy to surrounding nuclei. There is usually enough thermal energy in the material for the nuclei to be flipped back. How do protons precess about an axis?[6] Spinning protons when in the presence of an external magnetic field do not arrange themselves perfectly parallel or anti-parallel to the magnetic field, as the nuclei always have equal but opposite magnetic charges they cancel out when there is no magnetic field. The particles tend to precess about the magnetic field lines, and this is illustrated in figure 1.3. The nuclei complete a full rotation around the magnetic field in a period that is directly proportional to the strength of the external magnetic field. As you can see from the figure 1.4 the period gets smaller for a larger magnetic field and thus the frequency of the precession increases. This frequency is fixed depending upon the strength of the magnetic field, and is called the Larmor frequency and the relationship between them is given by: f = (ω)/ (2Ï€) Where ÃŽ ¥ is a constant called the gyromagnetic frequency, which varies for each type of particle. In MRI the Larmor frequency is about 50 MHz, which is in the radio frequency part of the magnetic frequency spectrum and the magnetic field has a magnitude of 1 or 2 Teslas. Why is the Larmor frequency is of that form? TheLarmor frequencyinMRI is the rate of precession of the magnetic moment of the proton around the external magnetic field. The frequency of precession is related to the strength of the external magnetic field,BØ. TheLarmor precession of nuclei of a substance placed in a magnetic field B0 is calculated from Larmor Equation, the Larmor precession is measured in Radians seconds-1: ω = ÃŽ ³BØ Where ÃŽ ¥ is a constant called the gyromagnetic frequency, which varies for each type of particle, but in the case of MRI is a constant as you are only affecting hydrogen nuclei. As the external magnetic field would be uniform and constant, to work out the Larmor frequency you need to divde the Larmor precession by 2Ï€f. The frequency is measured in Hertz which is s1 and as ω is measured in Radians seconds-1 so to work out the frequency needed you divide this by 2Ï€f which results in the Larmor frequency which is per second. The Net Magnetization Vector The precession of the nuclei only has a small effect upon the total magnetic field, which is only a small increase in magnetic field along the external field axis. This is because there are slightly more nuclei in parallel to the external magnetic field, than nuclei which are anti parallel to the external magnetic field. Although all of the nuclei in the material will be precessing at the Larmor frequency, they all may not be in phase. So the tranverse waves created by the nuclei get cancelled out which means that there will only be a small increase in field strength in the direction of the external field as not all of the nuclei parallel to the external field will get cancelled out. Why do we need superconducting magnets to make the protons resonate? Superconducting magnets are used in magnetic resonance imaging of the human body because magnetic resonance imaging requires extremely uniform fields across the subject and extreme stability over time. By having the magnet coils in the superconducting state helps to achieve parts-per-million spacial uniformity over a space large enough to hold a person, and parts per million hour-1 stability with time. This is the reason for using superconducting magnets alongside the fact that they are able to produce a magnetic field of a magnituted of 1 or 2 Teslas. How to make the protons resonate? In order to produce a magnetic resonance image we need to make the protons precess about the external field lines in phase with each other ; which will produce a small net transverse field which rotates about the axis of the external field at the Larmor frequency. This is the magnetic field that can be detected and in turn produce a magnetic resonance image. These three stages are all depend upon the nuclei precessing in phase with each other, this is done by making them absorb radio-frequency radiation of the same frequency of the Larmor frequency. The absorbtion of the energy causes low-energy state protons to flip into the high-energy state, which means that the protons are anti-parallel to the external field lines and also precessing in phase with the applied signal, which in turn mean that they are in phase with each other. The number of protons that flip depends upon the duration of the radio frequency pulse, which is applied. How a magnetic resonance image is produced: In order for a magnetic resonance image to be produced, you need to be able to locate the part of the body that has an ailment, in order to do this three smaller non uniform magnetic fields are added to the constant field. If you look at figure 1.5 you are able to see how these magnetic fields are applied, with one running the length of the patient’s body, this is the z-axis and this is used to define slices through the body. The body in this diagram is the sample, with the other magnetic fields being applied in the x-axis and y-axis, within the plane of a slice. The magnetic field strength at any point is the sum of the four fields that sets a unique larmour frequency and phase at each point in the body. To actually produce an image a pulse of electromagnetic radiation is sent through the body at a set radio frequency. The protons with a Larmor frequency will absorb energy from the pulse and flip into the higher energy state. As a result a transverse field, which is rotating at the Larmor frequency, is produced for the specific part of the body. As a result of Flemings Left hand rule, the rotating magnetic field that is actually an alternating field induces an electric current in the detector. The image is gradually formed by sending a sequence of radio-frequency pulses through the body at different frequencies to pick out the Larmor frequencies at different locations. The signals produced and the relaxation time involved are processed by computer to assemble the image. How is a clear image is produced on the scan? The relaxation time is the time taken for the protons to fall back down to their lower energy state after the radio-frequency pulse is turned off. The protons fall into their lower energy state by passing their energy on into neighboring atoms. The relaxation time is measured by the change in the intensity of the signal induced in the detector. The relaxation time is used to show the contrast in tissue within an image, with the relaxation time dependent upon the nature of atoms close to the stimulated protons. Thus a clear image of the tissue can be seen. The safety of magnetic resonance imaging scanning: MRI is regarded as one of the safest ways of confirming a diagnosis, although there are some exceptions where a patient has form of metal in their body, which interferes with the powerful superconducting magnets, which allows a magnetic resonance image to be produced. An example of something, which could cause a magnetic resonance image to not work, is tattoos that have metal fragments in the ink that is used to form the image. The metal is dangerous because metal objects can be forcefully drawn to the magnet; if these metal objects are embedded in your body, they can be drawn to the magnet and cause damage.The magnetic resonance image can also be dangerous for pregnant ladies. Using magnetic resonance imaging to detect cancer in the body A future use of MRI is to detect cancer; cancer cells need far more energy than most other types of tissues in the body, so a new technique has just been developed where a patient suspected of having cancer is injected with glucose. This results in a differing brightness on the image produced with the tumor appearing far brighter. Although this is currently only a concept that is still some way from being used on the general public, and this is in part due to the fact that the magnetic field strength used to produce these results is far higher than being used currently and we would need to see if the same results would be produced at a lower field strength. Conclusion In conclusion by taking the simple model already in place MRI has a bright future in diagnosis and detection of diseases, with MRI being the safest form of diagnosis for soft tissue as a result of its non-ionizing nature and clear results that it produces. The future for MRI will become brighter as the cost of using it falls over time, so that it will be more freely available and thus use for mass cancer detection could occur for example. MRI has already had a major impact on practices undertaken by doctors in assessing a patients needs, and the use of MRI stands to continue these changes further as more uses are developed.

Julius Caesar Essay -- essays research papers

How Betrayal Led to Downfall in Julius Caesar   Ã‚  Ã‚  Ã‚  Ã‚  In the play, The Tragedy of Julius Caesar, William Shakespeare shows how friends often betray each other. Julius Caesar is about to be crowned king of Rome, when some well-known Romans decide that it is not a good idea for this to happen. They form a conspiracy and kill Caesar. Brutus, an honorable Roman and a very good friend of Caesar’s, betrays Caesar by killing him for the good of Rome. Antony, Caesar’s best friend and another honorable Roman, betrays Brutus by turning against the conspirators. Cassius, a respected Roman, and Brutus betray each other by arguing and destroying their friendship. All this betraying lead to many deaths in the play.   Ã‚  Ã‚  Ã‚  Ã‚  When Brutus betrayed Caesar for the good of Rome by killing him, he had no idea that he would regret it later on in his life. Brutus wanted to kill Caesar because he thought that if Caesar became king, he would forget who his real friends are and he would not pay attention to them. He also thought that Caesar would become too powerful and therefore did not want him to be king. This is shown when Portia says, â€Å"†¦Brutus hath a suit / that Caesar will not grant†¦Ã¢â‚¬  (2.4.41-42). Although Brutus had a clear conscience, the people of Rome did not. This eventually led to Brutus being driven out of Rome by the citizens. Not being associated with Rome anymore made Brutus’ life worse and he eventually took his own life as the only way to...

The Right To Die Essay example -- essays research papers fc

The Right to Die Modern medical technology has made it possible to extend the lives of many far beyond when they would have died in the past. Death, in modern times, often ensures a long and painful fall where one loses control both physically and emotionally. Some individuals embrace the time that modern technology buys them; while others find the loss of control overwhelming and frightening. They want their loved ones to remember them as they were not as they have become. Some even elect death to avoid burdens of lingering on. They also seek assistance in doing so from medicine. The demands for assisted suicide and euthanasia are increasing (Kass 17). These issues raise many questions, legal and ethical. Although neither assisted suicide and euthanasia are legal, many people believe they should be. A great number of those people may never be faced with the decision, but knowing the option would be there is a comfort (Jaret 46). For those who will encounter the situation of loved ones on medication, being treated by physicians, sometimes relying on technical means to stay alive arises a great moral conflict. I wish to explore this topic on ethical, not legal issues. Do people have a right to choose death? More in particular, are euthanasia and physician-assisted suicide morally legitimate? Euthanasia involves a death that is intended to benefit the person who dies, and requires a final act by some other person, for example, a doctor. Physician-assisted suicide, which requires a final act by the patient, can also be undertaken for the good of that patient. The essential point is that both involve intentionally ending a human life (Emanuel 521). But how, some ask, can we ever allow people to intentionally end human lives (even their own lives) without degrading human life? How, others ask, can we simply prevent people from deciding when to end their own lives without denying people the freedom so essential to the value of a human life? As these questions suggests, the debate about the right to choose death may appear to present a stand-off between people who endorse life's true value, and those who think life's value depends on the interests, judgments, and choices of the person whose life it is. Through self identification individuals evaluate their own lives and its quality through their own values and belief systems. In order to maintain human dig... ...' dignity. Euthanasia, for some people, may be seen as a more humane way to die. Bibliography Emanuel, Esekiel and linda L.

Justifying the Ways of God in Miltons Paradise Lost Essay -- Papers M

Justifying the Ways of God in Milton's Paradise Lost Through Paradise Lost, Milton ?justifies the ways of God to men?, he explains why man fell and how he is affected by the fall. He shows that although man had a fall it was a fortunate fall, ?felix culpa?. As a result of the fall there are bad outcomes that man and women will endure but it was a fulfillment of God?s purpose. In creating man, God gave him free will; he created him a perfect being but ?free to fall?. In God?s plan man will fall by his own fault. This allows God to show mercy on man and allow man to chose to be obedient and to love God by his own choice and to eventually end up in a better place. If man had not fallen then there would be no coming of Christ the savior, and no redemption, which are apart of God?s plan. When Christ dies for man, he begins the process of redemption leading to the Last Judgement Day and to a new earth and heaven. Although mankind will suffer consequences, they will find grace and mercy through God?s glory and through experience and k nowledge they will be able to express sincere love and know true happiness. Milton begins this epic poem by telling men what is going to happen to man through God?s prophecy. God speaks of the fall and the ultimate outcome. When God created mankind he gave them free will, this free will is what allowed them to fall. God gave them free will because without freedom there would be no evidence that man?s love is genuine: ? Not free, what proof could they have giv?n sincere? (III, 103). God allows Satan to rally his troops and continue on his battle against heaven: ?And high permission of all-ruling-Heaven/ Left him at large to his own dark designs? (I, 212-13). God does this because Sat... ...ghest victory? (XII, 568-69). Finally Adam expresses that he will never leave Paradise because he will always have it within him: ?but shalt possess/ A paradise within thee, happier far? (XII, 586-87). Adam takes what he can from the fall and makes it to his best ability, a fortunate one. Eve has had the pain of child birthing put on her as a punishment. She takes this a makes it a good thing: ?I carry hence; though all by me is lost,/Such favor I unworthy vouchsafed,/ By me the Promised Seed shall all restore? (XII 621-23). Eve is saying that isn?t even worthy of this gift, ?favor?, creating her own felix culpa out of herfall. Adam and Eve disobeyed God and for that there were punishments, however they both turned it around and made it the best as possible. Works Cited: Milton, John. Paradise Lost. Ed.

Third World

Nationssocl 105 midterm exam Short Answer Question #1 What comes to mind when you here the term â€Å"Third World†? Most of the people in the United States find it hard to come to terms with the life style and struggles that are associated with this term. The term, â€Å"Third World† was first introduced during the Cold War. During this time, the â€Å"First World† referred to the United States and its’ allies, â€Å"Second World† consisted of the Soviet Union and its allies and the â€Å"Third World† was associated with the non-allied and neutral countries.After the second world war, these countries, who were mostly new to independence, were left trying to keep up with the fast growing world economy. The countries that couldn’t keep up were in dyer need of foreign involvement to help them develop. Thus, the term Third World ‘development’ was introduced. These underdeveloped countries were categorized by their low per-capi ta incomes, high illiteracy rates, limited development of industry, agriculture based economies, short life expectancy, and were often unstable politically (class notes).Plans to help promote development in these â€Å"Third World† countries were first conceived at the Bretton Woods conference in 1944. Representatives of 44 countries met in Bretton Woods, N. H to talk about postwar financial arrangements. It was at this meeting that the International Bank for Reconstruction and Development (World Bank) and International Monetary Fund were developed.The World Bank consisted of five divisions the International Bank for Reconstruction and Development (IBRD; its main component), the International Development Association (IDA), the International Finance Corporation (IFC), the Multilateral Investment Guarantee Agency (MIGA), and the International Center for Settlement of Investment Disputes (ICSID) (answers. com/topic/worldbank). The two main divisions associated with development w ere the IFC and IDA. The IFC did its part by lending money to private business in developing countries.With fresh capital, the hope was that these businesses would be able to produce goods, which could then be purchased by the countries people and in-turn create a stable economy within the developing country. The purpose of the IDA was to help out the banks poorest countries by providing interest free loans. As seen in the class film â€Å"Life and Debt,† Jamaica was able to go to the World Bank and ask for a loan when they’re country was forced to come up with money that wasn’t available. This loan request was most likely handled by the IDA.Another institution that was created was the International Monetary Fund. With more than 180 countries as members, the purpose of the IMF was to help ensure the smooth international buying and selling of currency. The IMF met this requirement by stabilizing currency-exchange rates and by providing advice and technical assist ance to its barrowing countries. Member countries do their part by contributing operating funds and receive voting rights based on their involvement in international trade and national income.There are many terms that are associated with countries that have not reached an industrial state. Developing nations, third world, and global south are some terms that can be used in describing these nations (class notes). Being a country that is labeled by one of these terms can be tough. If you were a developed nation would you want to get involved economically with a country with lifestyle associated with these terms. This is why its it so difficult for the underdeveloped countries to get involved with the world economy because of their reputation and the biased judgment that comes with it.Short Answer Question #2 One of the main indicators of development in a country is its Gross Domestic Product or GDP. Gross Domestic Product is measures the amount of goods and services produced in a spec ific country or region. GDP has become one of the main statistics used by scholars to measure a countries development, however, some say that GDP is an inaccurate measurement and that it has created some problems as the main indicator for development. GDP includes goods and services that do not include a countries economic wealth and, on the other hand, excludes things that do.According to paecon. net, GDP excludes three main categories. The first category that has been excluded by GDP is household production. Statistics say that most people spend more than 17% more time doing domestic work than paid work. That means that most of the people in these developing countries are too busy doing work around the house. That includes activities such as house cleaning, cooking, and caring for their children. Are we to say that because these people spend more time caring for their families they are to be penalized for it with a decrease in GDP?Another problem associated with GDP is the amount of voluntary work that may occur in a country. What was once done by a paid professional and accounted for in GDP, could have now been done voluntarily. Therefore, societies with widespread voluntary work may will have a lower GDP but have a good economic well-being. Another big form of income that is overlooked by GDP is the informal economy within these developing countries. Informal economy includes any direct sale activities such as odd jobs, street trading, and most of all the black market.This selling of goods and services often goes untaxed and unrecorded therefore is not included into a countries GDP. Overall GDP overlooks many forms of income, which can result in a misinterpretation of a countries economic well-being. There are other aspects of development that can also being affected by a countries’ GDP. It is believed that the people are the real economic drive to a nation, as a result, the Human Development Index was created. The HDI is a combination of different statistics to help judge the development of the people within a certain country.These statistics include life expectancy, education, and GDP. Therefore, the HDI of a country can be underestimated if its’ GDP is incorrect. The HDI also helped introduce the Gender Development Index (GDI). The GDI is a measure of the achievement of men and women within a country and also takes into account the inequality. GDI has a direct relationship to HDI, therefore, if the achievement of men and women goes down or one genders achievement becomes increasingly higher than the other, HDI will go down. The next step in human development comes in the form of the Gender Empowerment Measure (GEM).This statistic is now related to GDI in that it takes the capabilities achieved by the men and women and shows how they apply them to everyday life. GEM focuses on if the genders become active economically and politically within their country. Because these forms of human development are intertwined, and G DP is included in HDI, a miscalculated GDP could result in a snowball effect causing all the numbers to be skewed. The measurement of Gross Domestic Product has a negative effect on most developing countries.GDP overlooks the presence of household production, voluntary work, and the informal economy within a country; which causes GDP to often be underestimate and the worth of a country seem much less. Short Answer Question #4 Third World countries grew at a rate of 4. 7 percent during the 1960s. The growth rate of the East Asian NICs was 7 to 10 percent. These newly industrialized countries of East Asian included South Korea, Taiwan, Hong Kong, and Singapore. These countries managed to fulfill the goals of the development project and raise their living standards politically, economically and socially.However, they also showed how development initiatives can be very selective and how other countries may not have the same success if the same path is followed. One of the first steps th ese countries took towards improving their economy was by receiving a healthy amount of foreign investment. A good amount of this capital was directed towards developing facilities to manufacture exports such as textiles, shoes, electronics, and other apparel. Foreign investors were drawn to the cheap yet efficient labor that was available in the Asian NICs, which allowed businesses to keep coming.These countries offered a comparative advantage through their low-wage but relatively skilled and educated workforce. As a kid it seemed as if every toy or electronic that was being used was branded with the mark ‘MADE IN TAIWAN’ or ‘MADE IN HONG KONG. ’ Throughout the 1960s and 70s, the East Asian NICs continued to grow into the industrialized superpowers we see today. Though the East Asian countries had great success following the development project, the result was not the same for other countries in the Third World. The manufacturing section in GDP was extreme ly low in countries such as Africa and Latin America.By 1972, the Oraganisation for Economic Co-operation and Development realized that one size did not fit all and that, â€Å"the measures designed to help developing countries as a group have not been effective for the least developed countries† (Development and Social Change: A Global Perspective). It was clear that different countries required a plan to deal specifically with their problems. It seemed to be too tough for the Eastern European Countries to follow the same path as those countries that had involvement with a western power.The countries that had once been colonized had hands on experiences on how a country should be run. These previously colonized countries also received aid in the form of export processing zones or free trade zones as seen in the video â€Å"Life and Debt†. These zones where specifically designed to create jobs and give the people of the country the opportunity to earn an income by prod ucing goods for the investing nation. Eastern European countries did not have that luxury. They, like other struggling Third World countries, focused on an agricultural based economy that proved to be not as successful.Every Third world country is going to respond differently to the development initiatives. The path taken by the East Asian NICs may not be suitable for another underdeveloped country. The East Asian path worked for the NICs because they had a workforce that could support the labor needed to manufacture ‘money making’ exports. Again, going back to the movie â€Å"Life and Debt†, the Jamaican workers were replaced by Asians whom were able to get the job done and meet the quotas set by the investing nation.I believe that every Third World country is given the same opportunity to develop and it is up to them to use the resources provided by the world powers to make a change. However, some Third World countries have dug themselves too deep of a hole. In the case in Africa, a massive debt burden has accumulated in the attempt to develop and foreign aid could only undermine Africa’s domestic products at this time (class notes). It seems the more these stagnant countries try to fight toward development, the more they slip toward increasing debt and a permanence as a Third World county.Essay: There are three main theories in development: modernization theory, dependency theory and world systems theory. The two theories that seem to clash ideals the most are the modernization theory and dependency theory. At the end of WW II the world was divided into three main divisions: Capitalism in the United States, Communism in the Soviet Union, and newly independent nations that became known as the Third World. The United States began studies on these Third World countries, hoping to promote development through their eyes instead of communist Soviet Union.Through these studies emerged a new bread of American political scientists who toge ther developed the basis for a modernization theory of development. The dependency theory, however, was created from a Third World perspective. It was designed with the developing country in mind and not through an already developed countries eyes. Both theories have different views on the right path to development. In search for a basis for its theory, the modernization theory became a hybrid of the functionalist theory and the evolutionary theory (So, Alvin.Chapter 2: The Modernization Perspective). Most members in the modernization school had previously studied the functionalist theory, therefore, it became the trademark of the modernization theory. The other aspect, evolutionary theory, supported the idea that Third World countries must evolve from a traditional to a modern society through technology and institutions. One of the main strengths of the modernization theory was that is was developed by the most powerful nations at that time, the United States.The United States had grown to become one of the most powerful countries in the world economically, socially, and politically. Although the gap between the rich and poor in the United States is still great, the poor are still better off today then they were back in the early 1900s. The weakness that ties along with that topic is that the United States assumed that the Third World countries had some form of stability and are going through the same problems that the United States faced in their early development stage, which is not the case.The governments in third world countries are often corrupt and not necessarily looking out for the best interest of the people. Therefore, what may have worked for the United States could not work in the Third World countries who are faced with different and more extreme problems. Another strength that goes along with the modernization theory is that it has worked before with the East Asia NICs. Countries such as Hong Kong and South Korea grew throughout the 1960s and 7 0s by manufacturing and exporting foreign goods.With the success that Eastern Asian had using the theory it’s hard not think that it could work in other Third World Countries. Another problem that could occur with foreign involvement, however, is that the Third World countries could become too dependent on developed countries to provide them with work. As long as underdeveloped countries are going to manufacture products at a cheap labor cost, developed countries are going to keep exploiting them for their own profit.The modernization theory has worked in the past, however, not all situations are the same and it can cause Third World countries to become too dependent on the core countries. The dependency theory is based around a completely different concept. The dependency theory was first developed in Latin America after the crash of the program U. N. Economic Commission for Latin America (So, Alvin. Chapter 5: The Dependency Perspective). In the 1960s Latin American faced a tough time of economic stagnation along with a crisis of orthodox Marxism. Revolutionists turned to the ideas of neo-Marxism as a to base their dependency theory.Unlike orthodox Marxism, neo-Marxism saw the development issues through a Third World countries perspective. This was one of the main strengths that went along with the dependency theory. It realized that each countries situation is going to be different and also takes into account the historical context of that country. Where modernization says to throw away tradition, dependency says to go with what has worked for your country in the past. Another strength is that it allows for countries to think of development on a more long-term scale.Instead of jumping from the manufacturing of one exploited good to another, you can become more dependent on the goods and services that your own country can produce which can allow the Third World countries to develop and stabilize based on their own best interest and not just working to please the west. However, leaving an undeveloped country to develop by themselves, could have very negative consequences. Everything is worse in the third world. The governments are more corrupt, the poor are poorer, and there is a lack, if any, of infrastructure.It seems as if they are set up to fail if left on their own. A negative aspect that goes along with that idea is, what happens when western influence is removed? If Nike decides to open up a factory in Thailand, they don’t just set up the factory and let it be run by the people of Thailand. The factory is managed by the west. Policies in the workplace are enforced by the west. A factory ran by a Third World country may notice a huge decrease in efficiency, due to lack of experience and ultimately result in them not being able to compete in the world market.Dependency theory allows for the Third World country to develop themselves based on their conditions, however, some of these countries are so underdeveloped that self -stabilization may seem impossible. These two opposing theories have offered ideas to help more current development situations. The World Bank offers loans to the Third World countries who need the economic help. However, you still have to pay them back with interest. A country who supports dependency theory than has to use that money toward building on their own and finding a way to make that money back.A current example of modernization theory would be the current war in Iraq. The United States sent military forces overseas to discard of the traditional lifestyle of the Iraqi people and help move them toward modernization. The ideas of dependency and modernization theory can be useful in dealing with current development issues. There is an on going debate on the right path to development. You could choose to follow the policies set by the dependency theory. Peripheral countries break away from core countries to develop independency and allow for a socialist revolution to knoc k of the old peripheral elites.Or you could decide that the modernization theory is the best route to take and receive aid from the west and allow for an international division of labor. Both theories have their positives and negatives yet both are reaching for the same goal of Third World development.Reference Page www. answers. com/topic/world-bank www. answers. com/topic/internationalmonetaryfun www. hdr. undp. org/en McMichael, Philip.
