Thomas Youngs Double Slit Experiment

Throughout the nineteenth century, physicists had a consensus that light behaved like a wave, in large part thanks to the famous double slit experiment performed by Thomas Young. Driven by the insights from the experiment, and the wave properties it demonstrated, a century of physicists sought out the medium through which light was waving, the luminous ether.  Though the experiment is most notable with light, the fact is that this sort of experiment can be performed with any type of wave, such as water. For the moment, however, well focus on the behavior of light. What Was the Experiment? In the early 1800s (1801 to 1805, depending on the source), Thomas Young conducted his experiment. He allowed light to pass through a slit in a barrier so it expanded out in wave fronts from that slit as a light source (under Huygens Principle). That light, in turn, passed through the pair of slits in another barrier (carefully placed the right distance from the original slit). Each slit, in turn, diffracted the light as if they were also individual sources of light. The light impacted an observation screen. This is shown to the right. When a single slit was open, it merely impacted the observation screen with greater intensity at the center and then faded as you moved away from the center. There are two possible results of this experiment: Particle interpretation: If light exists as particles, the intensity of both slits will be the sum of the intensity from the individual slits. Wave interpretation: If light exists as waves, the light waves will have interference under the principle of superposition, creating bands of light (constructive interference) and dark (destructive interference). When the experiment was conducted, the light waves did indeed show these interference patterns. A third image that you can view is a graph of the intensity in terms of position, which matches with the predictions from interference. Impact of Young's Experiment At the time, this seemed to conclusively prove that light traveled in waves, causing a revitalization in Huygens wave theory of light, which included an invisible medium, ether, through which the waves propagated. Several experiments throughout the 1800s, most notably the famed Michelson-Morley experiment, attempted to detect the ether or its effects directly. They all failed and a century later, Einsteins work in the photoelectric effect and relativity resulted in the ether no longer being necessary to explain the behavior of light. Again a particle theory of light took dominance. Expanding the Double Slit Experiment Still, once the photon theory of light came about, saying the light moved only in discrete quanta, the question became how these results were possible. Over the years, physicists have taken this basic experiment and explored it in a number of ways. In the early 1900s, the question remained how light — which was now recognized to travel in particle-like bundles of quantized energy, called photons, thanks to Einsteins explanation of the  photoelectric effect  Ã¢â‚¬â€ could also exhibit the behavior of waves. Certainly, a bunch of water atoms (particles) when acting together form waves. Maybe this was something similar. One Photon at a Time It became possible to have a light source that was set up so that it emitted one photon at a time. This would be, literally, like hurling microscopic ball bearings through the slits. By setting up a screen that was sensitive enough to detect a single photon, you could determine whether there were or were not interference patterns in this case. One way to do this is to have a sensitive film set up and run the experiment over a period of time, then look at the film to see what the pattern of light on the screen is. Just such an experiment was performed and, in fact, it matched Youngs version identically — alternating light and dark bands, seemingly resulting from wave interference. This result both confirms and bewilders the wave theory. In this case, photons are being emitted individually. There is literally no way for wave interference to take place because each photon can only go through a single slit at a time. But the wave interference is observed. How is this possible? Well, the attempt to answer that question has spawned many intriguing interpretations of  quantum physics, from the Copenhagen interpretation to the many-worlds interpretation. It Gets Even Stranger Now assume that you conduct the same experiment, with one change. You place a detector that can tell whether or not the photon passes through a given slit. If we know the photon passes through one slit, then it cannot pass through the other slit to interfere with itself. It turns out that when you add the detector, the bands disappear. You perform the exact same experiment, but only add a simple measurement at an earlier phase, and the result of the experiment changes drastically. Something about the act of measuring which slit is used removed the wave element completely. At this point, the photons acted exactly as wed expect a particle to behave. The very uncertainty in position is related, somehow, to the manifestation of wave effects. More Particles Over the years, the experiment has been conducted in a number of different ways. In 1961, Claus Jonsson performed the experiment with electrons, and it  conformed  with Youngs behavior, creating interference patterns on the observation screen. Jonssons version of the experiment was voted the most beautiful experiment by  Physics World  readers in 2002. In 1974, technology became able to perform the experiment by releasing a single electron at a time. Again, the interference patterns showed up. But when a detector is placed at the slit, the interference once again disappears. The experiment was again performed in 1989 by a Japanese team that was able to use much more refined equipment. The experiment has been performed with photons, electrons, and atoms, and each time the same result becomes obvious — something about measuring the position of the particle at the slit removes the wave behavior. Many theories exist to explain why, but so far much of it is still conjecture.

The Impact Of Art On The Life Of The Believer - 1378 Words

Throughout history, art has been an essential component of almost every civilization, both for its own sake and for the reflection it provides of changing social attitudes and political climates. Yet while art does serve an important role in secular society, how should it influence, and perhaps even change, the lives of believers? Does God value art? If so, how does He expect us to interact with both secular and religious works of art? This essay will address these and other questions by analyzing the definition of art, discussing the role of art in the life of the believer, and considering how to properly evaluate artwork. We will close our discussion with a reflection on the importance of encouraging artistic expression and appreciation†¦show more content†¦3). This latter definition is more comprehensive than the former because it explains that art requires skill and is a medium through which an artist conveys a message. Yet even this description is not completely accurat e. First, artists occasionally create ‘ugly’ artwork to express inner turmoil or to convey harsh truths about society. Second, not all imaginative designs can be considered great art. Although creating a mural for a home, for example, certainly requires imagination and skill, the mural might not qualify as a work of art according to the judgement of art historians. Perhaps a better way to ‘define’ art would be to utilize a multifaceted approach, such as that suggested by Jeffrey T. Dean. Dean proposes that in order to determine whether a certain work can truly be considered art, it should be compared to â€Å"radial categories† of artwork (31) in the context of the â€Å"historical narrative† of art (29). In other words, the item in question must have some relation, whether direct or indirect, to a recognized work of art, and the connection between the two pieces (if one exists) will likely correlate to known developments in art history (31 â €“ 33). Based on these definitions, what types of creative works would not be considered art? According to Maria Khan, â€Å"Art is derived from our external and internal experiences. Art is a projection of what you experience, how you view the world and what you want to

Hunger Games Free Essays

The Hunger Games Essay By: Yasmeen Sahibzada The Hunger Games is a story of a 16-year old young adult named Katniss Everdeen who changes by her fate of entering the annual Hunger Games. The Hunger Games is an annual televised fight to the death. This event is held to entertain the Capitol. We will write a custom essay sample on Hunger Games or any similar topic only for you Order Now The Capitol is a utopian city where the Panem’s most powerful and wealthy live. Over the course of the book, Katniss enters the games, finds fake love, becomes a part of the star crossed lovers, and finds herself not able to let go of the boy with the bread. In the beginning of the book, Katniss is already well matured and takes the leadership role in her family. Although she is practically an adult, she cannot handle the stress when her sheltered sister is chosen to be in the Hunger Games. Due to this stress, Katniss volunteers herself in the games. In her time in the games, Katniss fully understands how life as part of the districts is meant to be. The Capitol dictates everyone’s life purposes and cannot be changed. Katniss has formed a real bond with Peeta (the boy with the bread†¦long story) who is faking their love for their immunity. Afraid to lose Peeta, they both pretend to eat poisonous berries so they will both win the games. This angers the Capitol because they have just been shown as weak but cannot purposely murder their victors and still seem innocent in all this chaos. Towards the end of the book, Katniss can really hold her own. Now, instead of only risking her own life in this act of defiance, she has sparked a rebellion in the districts. Katniss is the Girl on Fire, named for her distinct costume in the tribute parade. It is now Katniss against the oppressive government. This is the time when Katniss decided that she is the change that Panem has needed for the past 74 years. The theme of The Hunger Games is simply manipulation. Everybody living in Panem was trained to think the Capitol made the games to protect the people from another civil war when really, the games were made to show the people of Panem who’s boss and to not mess with them. They are forced to send their kids off to their guaranteed death but they can’t do anything about it because the Capitol is in control. The fact that Katniss overlooked the lies she was fed to realize the truth shows a lot on her character. In conclusion, I really enjoyed reading The Hunger Games. The writing was at Collins’ all time high, considering she also wrote for Little Bear, a show that I loved as a child. I enjoy very futuristic and rebellious series. This is the main reason as to why The Hunger Games sparked my attention. How to cite Hunger Games, Essay examples Hunger Games Free Essays The Hunger Games is a fictional book. which establishes the relationship between the protagonist Katniss, and the protagonist Peeta. Katniss is a 16 year old girl who lives In District twelve, Panem. We will write a custom essay sample on Hunger Games or any similar topic only for you Order Now She Is the sole provider for her family and competes in the Hunger Games, a game where two people from each of the twelve districts are chosen to fight to the death. Peeta is a 16 year old boy who is also from District Twelve who competes in the Hunger Games with Katniss. Throughout the book there s great debate on whether Katniss and Peeta are in love, or not in love. Katniss pretends to be In love with Peeta because It helps her In the Games, and It Is an act of survival. Peeta on the other hand is deeply in love with Katniss. Throughout the book Katniss often finds herself making multiple references back to her friend, Gale, who has been her best friend for years. She wonders what life would be like with Katniss pretends to be in love with Peeta. She sees It as her only way of survival In the Games. When she and Peeta are in an affectionate state, the Capitol audience is ntertained. This results In her and Peeta getting both food and messages from their mentor Haymitch and their sponsors. Luckily, they entertain the audience enough to survive the games but towards the end of the book Peeta says to Katniss, â€Å"It was all for the games, how you acted. † (Pg. 372) This is legitimate proof that Katniss only pretended to be in love with Peeta. Based on much evidence from the book, it is revealed that Peeta is deeply in love with Katniss. Prior to the beginning of the Games, both Katniss and Peeta had to take art In a pre-game Interview. In Peeta’s Interview. he tells the audience how winning the games would not help his situation because he is deeply in love with Katniss. Katniss was not happy with Peeta’s statement, but later In the book calmly asks him, â€Å"Peeta, you said at the interview you’d had a crush on me forever. When did forever start? † (Pg. 300) Peeta responded, â€Å"Oh let’s see. I guess the first day of school. We were five. You had on a red plaid dress and your hair†¦ it was in two braids Instead of one. My father pointed your out. (Pg. 300) This is the most heart-felt moment between the two; however Katniss only asked Peeta the question because she knew she had to keep entertaining the audience. Her strategy to manipulate Peeta’s emotions was a great advantage to her game. Katniss often makes references back to her friend Gale, her long time best friend that Is back home In District Twelve. She has mixed feelings about him because when Katniss was about to leave for the games, Gale was saying good bye to Katniss and was cut short with the slamming of a door. There are many misinterpretations about what Gale was trying to say to Katniss. Most people, Including Katniss, think that he ‘OF2 was aoout to say â€Å"l love you Inls unnnlsnea sentence OlsturDs Katnlss aurlng tne games when she has mixed feelings about Peeta. Katniss thinks to herself, â€Å"Gale’s not my boyfriend, but would he be, if I opened that door? † (Pg. 280) Any person who is truly in love would not be thinking about other men in this way. Throughout the Hunger Games there is great talk on whether Katniss and Peeta are in love, or not. Katniss pretends to be in love with Peeta because it helps her in the Games, and she uses it as an act of survival. Peeta on the other hand, is deeply in love with Katniss. During the book Katniss often finds herself making multiple mentions back to her friend, Gale, who has been her best friend and hunting buddy for years. She wonders what life would be like if she was with him. Too conclude, Katniss and Peeta are not meant to be.

Ethics Of Cheating Essay Example For Students

Ethics Of Cheating Essay Cheaters Never Win, Oh wait they dotheyre Cheaters Cheating is defined in the dictionary as, to deceive by trickery; swindle, however the dictionary fails to tell you if it is right or wrong to cheat. People have many different beliefs when it comes to cheating; some think its fine to do while others completely disapprove. I intend to show the different beliefs, from different perspectives of people, and also intend on proving which beliefs have the strongest and weakest arguments. An ethical egoist could argue that we have an obligation to cheat. Ethical egoists maintain the belief that we should act selfishly. We should do things that we believe in our self-interest, which is our own genuine interest. Egoist would cheat to benefit themselves, they believe that their own interest receives much more weight than everyone elses interest. Egoist realize that we are solely responsible for their own lives, therefore if cheating would benefit their lives then cheating is acceptable. If we did not cheat it would bring possible misfortune to our lives. However, it could also be argued by ethical egoist that we do not have an obligation to cheat. Egoist would agree that morality is about overcoming our selfishness and living our life with positive concern for the well being of others. Cheating is not looking at the well being of others, but rather doing the complete opposite. Unless everyone in the country had the answers to the test, then it would be considered good to cheat. Ethical egoist also like to think of themselves as good people, therefore they would want others to regard them in the same way. A cheater would not be regarded as a good person but rather, a bad person and a liar. A utilitarian would probably agree with cheating. Utilitarianism believes that morals are based on the happiness or misery of people. If a person cheated and got an A on the test, they would obviously be happy. Utilitarians also have the tendency to look at the short-term affects of a situation. For example, cheating would result in an A, however the broad perspective is that nothing would be learned, or if they were to get caught cheating they would fail, therefore in actuality they are not benefiting at all. Deontology on the other hand would argue that you should not cheat. Deontology assumes that we all have clear sets of duties that we ought to obey, these are given to us from God or our own reason. Therefore cheating is obviously wrong, so you ought not to cheat. Deontology believes that you have a set of duties that you follow. In deontological ethics, an action is considered morally good because of some characteristic of the action itself, not because the result of the action is good. Of the three approaches to ethics that are mentioned above I think that the egoists support of cheating makes the best argument. Although, I personally do not believe in cheating I do think that egoist do justify the act of cheating. Egoists feel that we should put our selves before all others and that we should do what makes us happy. They feel that whatever will benefit us most will in turn make us happier. I think the comparison of the strongest argument brings out the weaknesses in the other two arguments. I feel that utilitarianism does not have as strong of an argument for cheating, because they do not look at the entire situation and also they are interested in the happiness of themselves, cheating is not necessarily always going to make you happy. I believe that deontology has the weakest argument, they live by what you ought to do. They base all their decisions on God or morals that they were taught, they do not think on their own; they are told of their duties. It seems to me that deontology is almost robotic in a sense. These two arguments seem to concrete for people to actually maintain. English Essay I do not believe that any of the approaches to ethics would say that you had an obligation to cheat, but rather they explain their reasoning for why it would be acceptable to cheat. All three of these approaches .

Food Availability free essay sample

Identify and discuss a range of historical and contemporary factors which influence the availability of a popular staple food. This essay will consider the influence of historical and contemporary factors on such staple food as ‘’rice’’. The historical factors that have influence the ability of rice include migration of cultural groups, cash crop farming and farming technology. The contemporary changes of rice will include social, technology, political and economic. Before the Europeans arrived, Australian Aborigines people used hunting and gathering methods to collect food. Native foods were being known such as plants, animals and insects. Firstly, one of the most important historical factors that have influence the ability of rice is migration. Rice was introduced after Australia started to accept migrants from Asia. When people move from one country to another they bring the knowledge ‘’food’’ that they had with them. Therefore, rice has become popular because it is easily steamed or boiled and is eaten at all meals. We will write a custom essay sample on Food Availability or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For example, most migrants are not first generation. The family influence had taught the young family members the culture and beliefs about rice such as how to cook and eat. Secondly, cash crop farming is a type of farming for the purpose of making profit. A transnational company is a large company whose business dealings operate in many counties. Local people work the land and receive an income. For example, the famers will get a higher paid to grow things on the farm that being requested by the companies but the disadvantage is its high to start but then de-values. So, the lack of rice had been struggling in Australia. Thirdly, farming technology. Rice is a very hard staple food because it takes about 2-3 months to grow. Farmers used to use animals such as buffaloes or cows to help them farm. It’s tiring and uses lots of energy but it’s still convenience for people every day needs. Nowadays, Developed countries like Australia uses the knowledge of food production and processing to help to increase the availability of food. Social is influences by society which means that the variety of people inspire what we eat. We are now more understanding of the cultures and lifestyles as we are living in a multicultural world. Australian started to get to know more foods such as Asian, Italian, Mexican, etc For example, we all know that Asian countries such as China have rice for their everyday meals. We also know that rice goes with every meals and can be eaten with soup and people influence this to one to another. In addition, technology influences microwaves and rice-cookers which mean that we are being able to cook rice faster and easier. For example, you can go out to buy a package of frozen rice and microwaved it for 3 minutes or you can use a rice cooker to cook by putting your rice in and press start. As there are many choices you can keep it warm for a very long hours, non-sticky rice or quick cook. It saves time and labour. Where we look back 200 years ago, we did not have the ability to cook rice like the new technology. Plus, Marketplace is where consumers purchase rice from. The accessibility has been changed because we are able to plant rice ourselves. We have a choice to purchase such as online payments, shopping under one roof and the stores are located most of the places. Also, it’s cheaper than importing rice from overseas. Moreover, the political is a system of government in a country. The Australian government has a protection policy and a control on food imports of foreign products to achieve the goal. The government decides whether to let where rice imported from. For example, back in time, we were not able to import rice into our country because of our restrictions and low economic. To sum up, Economics of food means that people have money to buy food. Without money developing countries won’t have food available. But because we are living in a developed country we are able to have a high living standard compared to the poor countries. Rice is cheap in Australia therefore the lower the prices are the most people tend to spend the money. This money will be recycling. In conclusion, the influence of historical and contemporary factors on a staple food ‘’rice’’ that I’ve made above such as migrants, farming technology, cash crops, social, and technology, political and economic had changed Australia rapidly.

Batteries essays

Batteries essays As a child growing up, I was familiar with two types of batteries: the D size that was used in flashlights and the AA that was used for everything else. In todays society, technology is constantly changing and batteries are now becoming more and more advanced. We have seen the emergence of rechargeable batteries, lithium batteries, nickel cadmium batteries, nickel metal hydride batteries, lithium ion batteries, cordless power tool batteries, medical equipment batteries, batteries for communications, electronics, video, security devices, power tools, home appliances, battery powered toys, memory back-up and mobility. . Rechargeable batteries can only be re-charged so many times and the need for electricity is diminishing as batteries are becoming more powerful. They are now seen as a chokepoint in the use of alternative energy. Three sources of energy that I will focus on are Nickel Metal-Hydride, the new and improved Lithium Ion and Fuel Cells. Nickel Metal-Hydride (NiMH) batteries were introduced in the early 1990's as the new high-tech replacement over older chemistries like Nickel Cadmium (NiCd). Although they may have a very slight memory effect, NiMH batteries are much more reliable than previous chemistries. Compared to a NiCd battery of equal size, a NiMh battery will run for 30-40% longer on each charge. NiMH batteries can also be recharged 60% in just 15 minutes. Longer Nickel Metal Hydride batteries stay powered up longer, have no memory to drain and are environmentally friendly: mercury-free. Most new laptop computers and cordless phones are equipped with these cells now. One disadvantage of this battery is that its very sensitive to overcharging and complete discharging. The self discharge rate is very high so its not a good idea to leave them sitting around for even a couple of weeks. The introduction of lithium-ion technology represented a breakthrough in safety from the old lithium metal batteries. Lit...

Business Strategy Essay Example | Topics and Well Written Essays - 1500 words - 3

Business Strategy - Essay Example Jayesh (2012) further added that strategic alliances differ from mergers and acquisitions on the aspect that under strategic alliances, the partner companies maintain their autonomy or independence, which is not usually the case under mergers and acquisitions. Secondly, companies that form strategic alliances are not usually involved in direct competition but rather they offer related products and/ or services that are directed towards similar target consumers. According to Dorata (2012), there are various forms of strategic alliances and they include direct cooperation, which is the most common. The second form of strategic alliance is joint ventures whereby different companies come together and form a separate entity that they jointly own and manage together. The other form of strategic alliance is minority investments mostly in new and fast growing business organisations. Advantages Dorata (2012) in his writings listed the most common advantages of strategic alliances of which one of them is the fact that it enables companies to offer a wide variety of goods and/ or services to their consumers without incurring huge cost or spending lengthy durations in developing new products. Secondly, Dorata (2012) noted that businesses usually enter into strategic alliances to obtain competitive advantages that they would not have otherwise obtained if they operated on a solo basis. Therefore, strategic alliances enable businesses to expand more rapidly while still maintaining their autonomy unlike mergers and acquisitions strategy. Consequently, it is correct to assert that strategic alliances enable businesses to expand its customer base since it is able to reach a wide target market. Specifically to the car industry, Jayesh (2012) stated that among the companies that have recorded competitive advantages because of strategic alliances include Fuji and Toyota, which have jointly cooperated in various projects. Fuji gained an advantage from its strategic alliance with To yota based on the research and development that was conducted by Toyota that lead to the development of the Toyota’s gas-electric Prius hybrid model. Because of their strategic alliance, Fuji was also able to develop their first Subaru hybrid mainly based on the Toyota technology that was used in the manufacture of first gas-electric car (Hill, 2010). Another strategic alliance in the car industry is the one between Fiat and Chrysler that enabled the two companies to share their technology, distribution channels, and vehicle platforms. This strategic alliance was viewed to be of much benefit to Chrysler, which was struggling financially at the time when both companies where entering a strategic alliance and therefore, it was able to gain added advantages without losing its independence despite its financial position at that time (Hill, 2010). Another example of strategic alliance that demonstrated the advantages of strategic alliance over mergers and acquisition is the one be tween General Motors and Fiat that enabled both companies to benefit from reduced cost of operating, common architecture and platforms, increased efficiency in financial service operations, and cross-sharing of automotive technologies (Hill, 2010). Disadvantages According to the writings by Dorata (2012), the key disadvantage of strategic alliance is because of the fact that neither of the companies gains

Critical Thinking and Ethics Essay Example | Topics and Well Written Essays - 250 words - 1

Critical Thinking and Ethics - Essay Example This is because what can be seen as ethical in a particular situation may be viewed as unethical in a different context. Location or culture of communities also illustrates significant roles in understanding the ethical considerations relevant to that situation. This process is greatly improved through critical thinking applications. To give an instance in business ethics, a practice or product acceptable in one culture can be totally unacceptable in a different culture. Also, some cultures ethically embrace women in the workplace, but other cultures discriminate at women at the workplace. Critical thinking application, enable individuals understand situation so as to develop appropriate ethical considerations in a particular context (Moore, 2012). Critical thinking is connected to ethics through diverse thinking of individuals in relation to approaching ethical issues or practices. Individual eliminate the most probable approaches; this is until (s) he reaches or settles on the most appropriate approach for the given situation (Moore, 2012). Critical thinking is also linked to ethics through considerations of approaches individuals utilize in differentiating personal ethical concepts with organizational ethical concepts. Individuals have unique ethical considerations; they must separate these from organization’s concepts. Ethical decision making is important regardless of adherence to rule of logic. This is because ethical issues differ from one context or environment to another (Solomon, 2004). Decisions should be made in accordance to the acceptable practices of the applicable or relevant organization and

MRIs and Other Issues in Medicine Essay Example | Topics and Well Written Essays - 750 words

MRIs and Other Issues in Medicine - Essay Example An X-Ray is also used to image internal structures of the body, but opposed to an MRI, an X-Ray is a type of high-energy radiation. X-Rays are made of electromagnetic radiation with wavelengths between ultraviolet and gamma rays, and are most often used in low doses for making images of internal body structures and in higher doses for treating cancer. A CT Scan (CAT Scan) is again, another form of viewing the internal structures of a person's body. CT Scans are in fact a computerized series of X-Rays, which can reveal tumors and small strokes in the brain. A computer is used to generate a three dimensional image, which are then analyzed and displayed for diagnostic purposes. An MRI is most often used for studying nerves, muscles, ligaments, bones, and other tissues in the body. Problems such as a disc herniation in the spine or masses or tumors within soft tissues are seen well on an MRI image. MRIs are most helpful and most commonly used by orthopedic surgeons; an MRI is particularly helpful at diagnosing many common orthopedic problems. Therefore the most probable explanation as to why and MRI would be ordered is if orthopedic problems are perceived to exist in a patient. What Would it be an Appropriate Situation for an MRI not to be Done There are several proper explanations for why an MRI would not be ordered for a patient. Firstly, an MRI is not the most accurate test. Although an MRI is useful in the diagnosis of many conditions, it is not 100% accurate in all cases, which means sometimes the problem will not show up in the MRI. Another primary reason as to why an MRI might not be ordered is because an MRI is usually "not the first step." (Cluett, 2006). In other words, there are other steps which should be taken in an attempt to figure out the problem, rather than immediately ordering an MRI. Lastly but certainly no less importantly, is the fact that an MRI is only a diagnostic test, and not a treatment. "An MRI gives some people peace of mind, but will do nothing to change the symptoms of your condition." (Cluett, 2006). Are There any Limitations on an MRI Although MRIs have major technological advantages when compared to other imaging modalities, there are also certain limitations which are present. Disadvantages are there, such as the fact that because of the small bore of the magnet, some patients experience claustrophobia and often have difficulty cooperating in the study. As well, some obese patients cannot be studied by an MRI. Patient throughput is also slower than comparative imaging

Company Communication Issue

Company Communication Issue Intro. Since 2013 the company has received reports that some consumers may not be pleased with Huggies diapers because they felt scary due to a supposed chemical burn on the skin. I as the chief communication director have instructed the public relations department to do a media content analysis in order to determine the real situation or impact. Through content analysis, we will be able to do a qualitative research focusing on the interpretation of some editorials, magazines, websites, blogs, social media, forums, etc. Content analysis is the systematic and objective categorizing of information, in public relations, this is used to measure the amount of media coverage and the nature of that coverage (Wilcox, Cameron, Reber, 2014). Content analysis enables public relations departments to reinforce responsive communication by including some factors such as the percentage of favorable, neutral, negative mentions about a company, a brand or service, the overall tone of mention, the percentage of articles that contain a key message point that some organization wants to communicate (Wilcox, Cameron, Reber, 2014). Body. After a study carried out through different sources, the public relations department took a sampling of media data categorized by type as follows. Conclusions. The problem is that there are reports of some websites that express complaints from some customers that the honeycombs are causing burns due to some chemical component. Actually, according to the media content analysis made, no conclusive evidence has been found this is really happening. Instead, the findings show that the brand has been gaining the trust of the final consumers over time. Kimberly-Clark Corp has been interested in innovation, earning some awards. The brand has educational programs for the use of the product in order to prevent misuse. They enforce the campaign about their passion for helping all babies, especially the smallest and most fragile like premature ones. The findings reaffirm that the company is doing a great positive publicity job for the brand, raising it to the second level of popularity in the United States. This work is reflected in sales portals such as diapers.com in which consumer feedbacks reflect an 85% satisfaction with the brand. I do not think these complaints will affect the brands prestige or its positioning in the market, I think the brand is strong enough to deal with it. I would recommend to the CEO to keep the eyes on these forums so that we follow up the possible increase of these complaints, and can proactively prevent any damage to the brand. At the moment it is not recommended to invest more than what is done so far in some positive image campaign to counter these rumors. Reference sources page Wilcox, D. L., Cameron, G. T., Reber, B. H.

Essay --

Eight people are invited to Indian Island, a piece of land that a famous movie star millionaire is said to have purchased. The one thing all these people have in common is that they were all somehow involved in someone’s death. Soon they all learn that they were tricked into coming to the island which will result in their certain deaths. In every persons’ bedroom there was a poem that hinted at how each was going to die, and ten porcelain figures on the dining room table that mysteriously disappear with each death. One of them was the murderer because there was no one else on the island, leading to suspicion, accusations, and chaos. In the end it was learned that two of the characters on the island did in fact plan all the deaths, but one threatens to tell people. In turn, Lawrence Wargrave kills him off. He was punishing these people for crimes they had committed then he himself committed suicide. In And Then There Were None, Agatha Christie develops the theme â€Å"o ne must atone for their sins† through the use of symbolism, setting, and internal conflict. In the novel, Christie utilizes symbolism to develop to the theme. Both the violent storm and the china figure represent many different things ranging from death to the character’s backgrounds. The fierce weather symbolizes the violent acts that took place on Indian Island and previous faults the characters had committed. General Macarthur for example was pinned with the death of one of his soldiers. He sent the man to a brutal fight knowing that he would die. Also, the vicious storm is representative of the murders that were occurring on the island. The porcelain Indian figures embodied each of the ten people on the island. As a person dies, one of the men mysteriously disappears... ...money she lost not only Cyril, but her boyfriend. This event left her in an almost depressed position. The image of him drowning is constantly on her mind whilst on the island where she is very often left alone to just her thoughts. Near the end she had begun regretting what she did. The memory and guilt of her actions affect her so much, she committed suicide. This in turn was her punishment for plotting the death of an innocent boy. Furthermore her internal conflicts lead her to the retribution of her actions. As seen through the use of symbolism, setting, and internal conflict, Agatha Christie has created the theme â€Å"no wrongdoing goes unpunished† in And Then There Were None. Each of the characters paid for their sins through death on Indian Island. Each character either took their own life, due to the regret of their actions or by it was done by an outside force.
