Manipulation in Documentaries Essay

Every night when we sit down to watch our much loved Grey’s Anatomy or Desperate Housewives, we know for a fact they are fictional dramas which allow us to escape the reality and boredom of our lives. We also realise the scripted shows use many tactics to manipulate our thinking. The producer does this to position us towards a specific view of life. But what do we expect from a documentary? We know documentaries to be faithful recounts of events; however, these events may be subject to just as much manipulation as the intriguing plots in our addictive shows. Many documentary makers include their individual cultural assumptions and discourses to distort the truth and position the target audience to react in a desired manner. This can be seen in the documentary, ‘Supersize Me’ by Morgan Spurlock and ‘Great White – Deep Trouble’ showcasing Peter Benchley, David Doubilet and Rodney Fox. Both producers desire to position the audience towards their discourse through their documentary. They accomplish this by presenting snippets of films, opinions and facts that agree with their discourse and disposing of the rest. ‘Super Size Me’, written, produced, directed by and starring Morgan Spurlock, is a producer dominated documentary. It shows Spurlock endeavouring on a thirty day McDonald’s binge to prove that regular consumption of the food is a fast way to heart disease, high cholesterol and obesity. Spurlock aims to prove his nutritional discourse by taking tests before and after the experiment to show the affects. Before the experiment began, Spurlock’s body showed healthy results both physically and emotionally, however, after the experiment, his body was physically rundown sporting clogged arteries, high cholesterol, weight gain and emotionally he showed early stages of depression. Spurlock’s aim in the documentary is to inform his audience that regular fast food consumption is extremely harmful to your body. It uses both fully narrated and self reflexive types of documentary to present the message. This means voice overs are used to interpret graphs, pictures and facts presented in the documentary to prove that fast food has a significant impact on the nation’s health. He also includes many techniques including camera angles, music and sound, lighting and many elements typical of documentaries. Spurlock uses Mise-en-scene to prove that obesity is a result of extreme fast food intake by purposely filming obese people walking through a shot at McDonalds. Spurlock also uses the technique of interviewing doctors and scientists to grab our attention and make it difficult for us, the audience, to make our own decision. He does this as the majority of us believe scientists and doctors have the most knowledge on this argument and therefore we will agree with his discourse. Similarly the documentary, ‘Great White – Deep Trouble’, produced by John Bredar, attempts to influence the audience to feel sympathy and love for the Great White which to many represents a killer beast. The documentary aims to manipulate us towards the view that sharks are gentle fish that are simply misunderstood by humans. Through the journey of David Doubilet, a famous photographer, the audience are presented with pictures, journal entries and filming of the Great White in the hope of capturing the perfect shot. One of the crew on the mission is Rodney Fox who previously had a bloody encounter with a Great White and survived. Although the majority of us would be too afraid to return to the water, Fox has chosen to partake in the mission of defending the creature. The producer uses this to his advantage by demonstrating that even someone who was attacked by a killing machine managed to love the animal and therefore we should too. The documentary uses techniques in order to create a calm ambience and make the shark seem vulnerable. They use relaxing music and bright lighting to create a sympathetic and almost angelic view of the shark. Camera shots are taken under water allowing the audience to see the scenery and true characteristics of the shark. The documentary provides close up shots to shows the sharks facial features and emotions. It also uses long shots to show the entire body and the provide insight into the sharks natural habitat. The documentary uses the feature of exposition to expose the true qualities of the shark in order to manipulate the audience. Both documentaries possess intertextualities that we are all familiar with. In general, when we see Ronald McDonald we are automatically reminded of McDonalds and their food products. In the Documentary, Spurlock shows Ronald McDonald as an evil clown rather than happy. This represents his negativity towards the restaurant. When watching ‘Great White – Deep Trouble’ our intertextualities towards sharks is that they are vicious man-eating machines like the shark off the movie ‘Jaws’. Although many facts, graphs and discourses are exposed and explained throughout these two documentaries it does not necessarily mean the producer’s opinion is correct. They simply want to manipulate and position the audience to believe what they say in order to sell their view to the public. When we hear the word,’ documentary’ our cultural beliefs tell us they are filled with true facts or recounts of events, however, we need to realise that documentaries are filled with individual discourses which aren’t essentially accurate. We as an audience need to ensure we do not fall victim to the producer’s manipulative techniques that are incorporated in the documentaries. In order to do so we need to be strong in our personal beliefs and discourses. That does not mean you should seclude all opinions from others. Be open to new ideas, but be strong in your own beliefs. That way you will not be manipulated as easily. Make your own decision and don’t let the producer sway that conclusion.

Grant And Lee: A Study In Contrasts Essay

In recent years, there has been enough thesis studying General Grant and General Lee in contrasts. No wonder, because they are some of the most iconic figures in the new history of the United States. Both became military under the pressure of family circumstances. Both were outstanding participants in the Civil war. But the memory of Ulysses Grant is passed on from generation to generation while tombstones to Robert Lee are now threatened with demolition. Let us turn to comparison and study in contrasts lives of Bruce Catton Grant and Robert Lee. Ulysses C. Grant was born on April 27, 1822, in Point Pleasant, Ohio. Already at an early age, the young general was helping his father on the farm. After visiting a lot of private schools, his father decided that he should make a soldier career. Thanks to the petition of Congressman Thomas L. Hemmer, Grant was admitted to the military academy in West Point, New York. Grant obeyed his father’s wishes, not experiencing much enthusiasm for the servicemen. In 1843, he received the patent of an officer and started serving in the 4th Infantry Regiment of the United States. By the time of war against Mexico (1846-48), comrades’ remarks about the excessive use of alcohol by Grant belong. After numerous warnings from his superiors, he resigned in the summer of 1854. Although his wife’s family had slaves, he found as right thing to fight on the side of the union. Soon Grant for his success in the military field was appointed general of the brigade. After under his command the Confederates from Kentucky were forced out, Lincoln conferred on him the rank of Major-General. Grant was distinguished by logic, calculation, and perseverance in conducting military operations, and his troops showed a high fighting morale. After the Civil War, Grant retained the main command of the US Army. In 1866, Congress conferred on him the rank of general. It was the war that gave Grant his place in life. Being a War Minister, he has accumulated extensive management experience, although he was repeatedly reproached for incompetence required for the highest state office. In the presidency, general saw an opportunity to maintain a war victory by restoring the political unity of the state and guaranteeing civil rights. Grant won elections in 1868 thanks to the program that promised reconstruction of the South, suffrage for liberated slaves and economic recovery of the southern states. But general in choosing ministers and advisers relied chiefly on the persons he knew the height of service. Promising much, Grant, however, was satisfied with the small. During his second term, no measures were taken to resolve social and political problems between races, so conservative forces in the South gained the upper hand. Also, a general refused his initial striving to reform the cabinet of officials, has managed to provide posts only to his closest friends. The extent of corruption and bribery cases surpassed all previously known. Criticism against Grant grew. The most lasting influence was â€Å"panic of 1873† when banks were closed, and the timid efforts of the ministry could not improve sad situation. Mismanagement, embezzlement and large speculation accelerated economic downturn. After the end of the presidential term, Grant departed from politics. The hero of the Civil War died on July 23, 1885, in New York. Despite military successes, in the history of the US, General Grant refers to weak presidents. He was considered as a passive politician who followed the directions of Congress, instead of implementing his own ideas. Venality represents his government in an unfavorable light. His policy towards the southern states is often assessed as half-hearted, as Grant nevertheless tried to protect the civil rights of the black population. One gets an impression that he perceived his presidency as a kind of vestibule to political rest. In combination with naivetà ©, such attitude created a danger of manipulation. Therefore, a general didn’t justify the hopes that were placed on him. Robert Edward Lee was born in 1807, in Stradford, Virginia. As his father soon had serious financial problems, in fact, mother raised the future general. If Grant’s fate was determined by his father, then Robert Lee’s life path was connected with economic difficulties. The only way out in similar situation was to enter the famous military academy West Point. Robert Lee, who was not only diligence in his studies but also a great physical force, could become an ideal officer in the American army. And he became it. While studying at the academy, Lee was one of the best Cadets, not having received a single penalty from a higher command. After finishing he was assigned to engineering troops. But the career of a war engineer did not give the desired advancement in titles. In addition, service in the outback was burdened by an officer who could not fully engage in his family. In the end, Robert managed to achieve transfer to cavalry. By this time he was already 48 years old. In 1861, Abraham Lincoln invited Colonel Lee to lead the land forces of federal government, as conditions in the Southern States heated up to the limit. Herewith, Robert was regarded as a convinced opponent of slavery. However, being a native of the South, a colonel wrote a petition for resignation, stressing that he was not able to participate in the invasion of his homeland. The general, who is seen as a symbol of militant slave-owners, for many years kept a large family for modest state salaries, and acquired slaves, only obtaining an inheritance at the age of 50 years. While the commander of the army of the North, General Ulysses Grant was a slaveholder. His â€Å"laborers† were freed only after the amendment to the Constitution abolishing slavery came into force in 1865. Colonel Lee turned to Jefferson Davis, the president of the Confederation, and offered him his services as a soldier. So, Robert rose to the general’s epaulets, engaged in the creation of a regular army of the southern states. Lee participated in the planning of numerous military operations and then headed the Army of Northern Virginia. Commanded by general, the troops achieved impressive success. Yielding to the northerners in the strength and preparedness, Lee defeated them after defeat. His name has turned into a nightmare for his enemies. Robert Lee enjoyed great respect from the opponents. In particular, Ulysses Grant called him â€Å"Ace Peak†. But in 1865 Lee’s army was forced to capitulate. The federal government amnestied Robert Lee. He died in 1870, until the end of his life engaged in the organization of assistance to former soldiers of the Confederation. For a long time, merits of General Lee were recognized by a lot of US patriots, regardless of political beliefs. The situation began to change not so long ago when in America there was a â€Å"left-liberal† coup, expressed on a symbolic level in a rigid refusal of memory of all representatives of the Confederation. Thus, as we can see, General Grant and General Lee study in contrasts summary show that they were in the best light only in the military field. Of course, Ulysses proved to be luckier than Robert. But, as we know, the truth is always on the side of the winners. Lee’s reluctance to fight against the southern states testifies to his high moral qualities. After all, he did not advocate the extension of slavery, but for the independence of the South. Whereas Grant refers to the type of people who try to transfer their successes from one sphere to another, without sufficient knowledge and skills. In this regard, General Lee is more honest, because he was engaged in one thing, not pretending to be a connoisseur of politics.   

So close to the Border

Pavel lay in the frost frozen. The frost spitting and eating away at the skin on his face and hands. Too dangerous to move. Undressed, just the upper body covered with a think pyjama like shirt, sleeves too small only reaching just below the elbows. The shirt soaked though with icicles dangling off the edges. He lay there motionless with no thought about how cold it was, just concentrating on those guards, standing there wrapped in their thick coats smoking slowly. With no moon this night there is only two faint body like structures with two orange circles floating in the air. Not much longer to wait for the change of guards. These eager but nerve racking moments, with the urge to just to run from the camp but thinking if he could just wait a few moments. Freedom was waiting for him just over the border. The scent of waffles wafting through the air making his stomach really churn. With the wire cutters in his hands, which were buried at least a foot into the snow just waiting†¦ All it needs is a few snips and there's a whole in the thick barbed wire. He lay there watching as the guards threw away their cigarettes. He had precisely 3mins to get out of the camp to a small amount of safety. He knew that he would only be safe once he had crossed the border. Pavel had no idea what date it was, he could only tell that it was probably about 7:00 for the sun had set along time ago. Now was his only chance. He began cutting away at the wire, panicking. Finally the hole is cut. Crouching low so that he doesn't give away his silhouette, he slowly moves across an open plain, which goes on for about 75 yards. Once he reached the brush he gets out his secretly hidden map. It is sewn in on a handkerchief, which his Uncle gave him just before he died. He could not see the map. He knew that the direction he was heading in was south which was the general direction he was going in. He could tell that he was going south for the south wall was where the people who were going to be gassed had to line up before being taken away. He had escaped from the direction of the south wall. Pavel is a seventeen-year-old boy. He was born through a Christian family but adopted by a Jewish family about 14 years before the war broke out. They counted him as Jewish even though he had not been circumcised because he was found in a Jewish temple and his records were found of his life and about being adopted. He was straight away sent to the camp in Auschwitz and sentenced to death after a few years of labour. He escaping for it almost time for him to meet his death and he wants to find the rest of his family. He was caught in the church. His family got away. I am frozen with fear now. I had got the main part done which was getting out of the camp. I can't think what to do. I lay still, huddled up on the ground, just staring out into the night. It's a big country, but now made small for there are troops stationed everywhere. The sirens might even go of back at the camp in about 30 minutes. I started walking when a German sentry walked on to a path directly coming my way. I could tell there was no news of an escape; otherwise these soldiers would be looking a lot more alert. They rifles were slung up on their shoulders and dangling while they were smoking calmly. I waited for them to move past me. I didn't want to give myself away already. The footsteps died out in a just a matter of seconds. I struggled to get back up and when I did I staggered in the brush along the path in the southern direction. I was walking for about an hour now and had past quite a few machine gun posts. My aim was to get to Hungary, I don't know how but I was going to do my best. I heard noises and smoke from the chimney of a hut. For a moment a thought it was just drunk soldiers. I crossed the path and came close up to an open window. The soldiers were not drunk. I saw them loading rifles and magazines with bullets and from my faint knowledge of German language they were talking about an escape from Auschwitz. I knew this was I. I waited for the Germans to go. I heard their motorbikes revving up and watched them leave up the windy path. I didn't have a clue where I. I went close to the light coming out from the window and I took out my handkerchief. I found the area that I was in. I was astonished by how good this map was to me. It had fooled the guards at Auschwitz and now it was going to get me past the border. I realised I sill had around 100 kilometres to go before I reached the border. It sounded a long way. I saw nobody inside the hut. I could see German trench coat near the window and I reached across to grab. A voice suddenly in a gentle tone said, â€Å"Food? † I didn't reply. I was paralysed with fear and a turned around after a few seconds. Again came the voice of a young man, â€Å"Would you like some food? † I replied, â€Å"You're Polish? † His accent seemed a bit funny but I assumed he was a decent person. â€Å"Yes†, said the man, â€Å"You have runaway haven't you. You're Jewish aren't you? Would you like some food? † Ignoring the offer I carried on the conversation. † I am. Do you think there is any way I could get to the border quickly? My feet have worn out. I have no shoes. Will the Germans be coming back here? † † They will, but don't worry your safe here. You must be so tired and cold. You can stay in my cellar; the Germans think this will be the last place someone would stay. I have wine going to the Germans a the border, you might be able to hitch a lift. † I didn't yet know if I could trust this man and his ideas for me. â€Å"Could I have some food and some shoes? † I asked. He stood there thinking. † I don't have shoes but I do have some food. Here. † He lay down some bread and butter. I was happy. There was about half a loaf. In Auschwitz we only got about 3 slices of bread without butter a day. I had suffered bad symptoms. I kept on fainting. I finished eating all I could and got up. I was being very cautious of this man. He led me outside the hut and there was a little door entering the ground. I jumped in. His last words ever to me were, â€Å"You can stay here for the night. The delivery truck will beep when he gets here so you will hear it and wake up. I will tell him of the situation. † â€Å"Thank you. Thank you so much. † The door shut and me last glimpse of light faded to nothing. BEEP! I heard the sound of the truck and there was light coming through the cracks of the door. I opened the door slightly and peered out through the gap. There was a black truck there. I knew what to do. I climbed out and jumped into the back. There were some empty cargo boxes and full ones. The full ones were at the back of the truck and the empty were towards the front. I jumped into an empty box. I was worried. I didn't know who was driving, what if it was a German in disguise and this whole thing was a set up to get me returned back to the camp. The engine started off and the vehicle started moving. I never realised it but there was food in the box. There was some bread and cheese. I thought this was a luxury. The truck had been driving for about half a day. I thought we were lucky because we had not been stopped once. The truck glided gently into a halt and I heard some voices. I heard the driver explaining that we have wine for the officers on the border. The back of the truck opened up. I could see a German officer through the holes in the box. He stepped into the back and opened up a box. I could tell by his face that he was satisfied. He took two bottles and gave thumbs up to somebody. I heard the back door slam and the truck started off again. The driver gave a tap to the wall between the front and back of the truck. I assumed this was my call to get out. I slipped out of the box into the night. I could see the watchtowers and there were lights moving all over the fields. The place was swarming with Germans. I thought this was going to be the last of me. I knew I wasn't going to make it. I heard the truck go off and I started to make my way out of the area because it could be the centre of attention to the Germans. I was trundling my way through deep snow when I spotted a German post. I avoided it and found my self in the middle of a spotlight. My instincts were just to run. I heard bullet fire. I then got shot in the back. I was just at the barbed wire and I started hacking away at it with my wire cutters. At this moment Pavel was shot in the back of his neck. He carried on cutting through. Eventually a hole was made. Shots were landing all around him from MP40 fire. He jumped through the barbed wire and his ragged trench coat got stuck on the wire. He tried to set himself free and got shot in the back. There was just a little whole in his back but the round exploded in his stomach as it came out. HE carried on trying to set himself free when six German soldiers approached with their rifles locked into their soldiers. Each of them aimed at Pavel and fired. Pavel lay there strewn along the barbed wire. He did not know this but he died two days before his eighteenth birthday and his family had all died in concentration camps. This is not based on a true story but this would have happened a lot in the world war two in Poland.

Performance Management Essay Example | Topics and Well Written Essays - 2250 words - 3

Performance Management - Essay Example This paper presents a performance management system for retail sales associates of a clothing and fashion accessories retail store. The ultimate goal of the system is to help improve revenue and customer satisfaction. By virtue of you role, you will be the first contact the customer makes when they enter the store. As such, you will be required to possess adequate knowledge of the companys products. Your role will include, but not be limited to, the following: For a start, you will be remunerated at the rate of $8.00 per hour. However, based on your performance, this rate could be increased in the future. In addition, you’ll receive a bonus every time you exceed your weekly sales target by at least fifty percent. Several key behaviors are necessary first for successful job performance of sales associates then for the realization of the goal of the performance management system(Haines III & St-Onge, 2012). Three of them are discussed here. The first is the habit of the sales associate updating their knowledge of the company’s products. Clients are impressed by sales associates who demonstrate deep knowledge of the products they seek to sell. This impression goes a long way toward influencing the customer’s decision to buy. By contrast, sales associates who exhibit ignorance of their company’s products are a put-off. Given that that the company carries new brands of merchandise from time to time, it will be necessary that every sales associate acquaints themselves with these brands. The second desirable behavior is the habit of going the extra mile(Grffin & Moorhead, 2010). Most sales associates will be happy and satisfied with simply helping the client locate the product they ask for when they enter the shop. It is a well-recognized fact that with a little calculated â€Å"guidance† of the sales associate, the client is likely to end up buying more items than they had intended. For instance,

Piano Essay Example | Topics and Well Written Essays - 500 words

Piano - Essay Example There is no motion anywhere; like everything is paying tribute to the beautiful music. In this sense of extreme calm and motionlessness, I can feel goose-bumps every now and then when an unusually appealing note gets me overwhelmed. When I am overjoyed with happiness, the sound of piano helps me sustain that feeling of being overjoyed. Particularly, if a fast track is being played, nothing matches the occasion better than that. When I attain this match by fortune, I cannot help dancing. While I know that I am a very pathetic dancer otherwise, my dancing skills unimaginably get polished at such occasions as if by magic or a miracle. I dance like I have learnt dancing formally from some dance school. Maybe it is this frequency that I share with the sound of a piano that it helps me explore my hidden capabilities and surprise my friends and family with that. When I hear piano, it frequently reminds me of my second birthday when I had received piano as a gift from my dearest grandmother who is no more with me today. Thus my grandmother established my relation with piano the very day. I have spent my early childhood at my grandmother’s place and she is one of the people who have not only shaped my life and personality but have left many positive influences and examples for me to follow throughout my life. That was the first time I happened to own a piano. Probably that is where my association with piano started and has continued to date. May be this is the reason why at every special occasion, I feel incomplete and undone unless I have heard piano and cherished a memory of my grandmother. Piano affects me almost just like alcohol affects people. Drunk people excel in the emotion that they have at a particular point in time unless something different happens to catch their attention and make them take a turn. Likewise, piano helps me retain and indeed strengthen whatever feeling I have at a particular point in time while I

Should SDSu student use ADHD drug to help them study Essay

Should SDSu student use ADHD drug to help them study - Essay Example On the other hand, there are students who abuse these drugs by taking them even though they do not have the condition. This is very common among students who have high expectations to excel. Despite the significant risks associated with ADHD drugs, some students take them without proper medical advice in order to cope with high expectations and academic standards. Even for students with ADHD, the drugs only improve concentration and attention but do not help when it comes to studying. Preliminary investigations show that the primary motive as to why students take ADHD drugs is for study help. Since ADHD drugs are one of the most abused drugs among students, the current paper examines whether SDSu students should use these drugs. Using ethical and logical (health concerns) arguments, we argue that only students with special needs, having been examined by relevant specialists, should be allowed to take ADHD drugs. Application of Appeal of Logic Attention Deficit Hyperactivity Disorder (ADHD) was originally believed to be a pediatric condition. Children who suffer from ADHD continue experiencing the symptoms even in adulthood. Adderall is the most common prescribed drug for students with ADHD, with Ritalin and Dexedrine. . ADHD stimulant is a legal drug as compared to other illegal drugs sold on the street. When one buys these drugs, it is evident that dirty druggies like those who prepare cocaine do not prepare the drug. Therefore, SDSu students with special needs should use ADHD drugs because most people trust the drug’s medical founding. It is quite evident that medical experts would not deceive the public about the ADHD stimulant quality. ADHD drugs are perceived to be stimulants because they expand dopamine in the brain. There has been an increase in the consumption of ADHD stimulants in the United States of America that is, individuals’ expenditure on these drugs rose from 83% to 90% from the year 1993 to 2003. The increase in consumption of th ese drugs does not only apply in United States but also the rest of the world. Usually, students use these drugs to curb exam pressures since sleepiness and fatigue makes it hard for students to study. However, students use these drugs not necessarily to score high but to concentrate during study. In addition, using the ADHD stimulants is not legal because Adderall is a controllable stimulant just like cocaine (Oremus, 2013). Application of Appeal of Emotion Research indicates that some students take ADHD stimulants for the right reason. Students use these stimulants to encourage positive outcomes: good and high grades. For instance, Oremus (2013) explains that these drugs allow one to hold attention for long hours when performing a task. The stimulants also increase individuals’ ability to remember, multitask, and to be faster in handling activities. Crusius and Channell (2010) claims that taking ADHD drug helps students think better and perform successfully and professional ly in schoolwork. However, ADHD drug is for individuals who want success in their work towards achieving their goals. According to Oremus, (2013), Cambridge undergraduate students who employ ADHD drugs in their studies and their consumption has resulted to enhancements such as recollecting of information within a short duration and planning capabilities. If a student wants to experience a

REFUGEE LAW AND PROTECTED PERSON in Canada Essay

REFUGEE LAW AND PROTECTED PERSON in Canada - Essay Example Firstly, the Immigration and Refugee Board of Canada together with Citizenship and Immigration Canada (CIC) provides for protection when a person cannot live permanently without fear of persecution (Canadians, 2010). In assessing gravity of Serbians in Croatia, we find that the client meet this constitutional provision. In assessing magnitude of torture and persecution in Croatia, it will be prudent to examine Croatia and â€Å"Ethnic Cleansing† (http://www.cgs.c.u-tokyo.ac.jp/download/cgs01_07_shimizu). In this article, it details how hundreds of thousands of Serbian became victim of genocide. As early as 1941, 750,000 defenseless Serbs were killed in cold blood (Daiute & Turniski, 2005). UNHCR report blames political rivalry during these early phases of anti-Serbian campaigns (http://www.refworld.org/country,,,,HRV,,553f617f4,0.html). In the recent past, the Croatian captured media attention when Whistle blower Chris Hedges came out to highlight plight of Serbians in 1998. The International Criminal Court (ICC) implicated Defense Minister Gojko Susak for the senseless killings of Serbians (http://45lines.com/levar/scare/scare.html). More recently, the cry to end tribulations of the Serbian population continues to grow. Many young and old are living in fear. Roman Catholic Church, the majority rising against Orthodox mainly the Serbians is evident (http://archbishop-cranmer.blogspot.com/2011/04/at-last-true-horror-of-persecution-of.html). The report further is supported by the ICC decision that found guilty Anto Gotovina and Mlade Markac of commanding operations to kill the Serbian

How to do research project on management - Essay Example There are numerous means of conducting qualitative research, methods such as focus groups, surveys as well as interviews. To facilitate the process of uncovering insightful findings, the author opts for a multi-method approach for a research strategy allowing for several methods of collecting the data. For the purpose of the study, surveys were used in conjunction with telephone interviews. To triangulate these primary data the author has also accessed the websites of the organizations for their core values, mission statements, messages and other secondary data as internal company records including organizational structures, annual reports etc. Such data can be â€Å"qualitatively analyzed† provided the â€Å"relevance to the study topic† is present. In designing surveys, it is important to establish the purpose of the survey and consider the key variables, which are being identified and how the data gathered will be analyzed.

Professional Project - Rehearsal Studio Dissertation

Professional Project - Rehearsal Studio - Dissertation Example This is inclusive of the sociocultural conditions and other economic situations that are now a part of the UK. This also includes the trends and conditions which are in the current environment and how this will affect the capability of having a rehearsal studio within a given area. The aims and objectives of the methodology will then be able to determine if it is financially feasible to begin a rehearsal studio as well as how the response would be from the social perspective in the UK. Design There will be two studies that will be used to determine whether a rehearsal studio can be incorporated into today’s climate in the UK. One consists of a qualitative analysis and the second a quantitative analysis. These will define the independent factors that would change the needs for a rehearsal studio and will show the impact which will be made when creating a rehearsal studio. The overall design will work to create the process of triangulation, or a mixed methodology. This particula r approach is able to combine several perspectives and to combine independent data to show how each is related to each other in the defining of a given situation (Tashakkori, 2006). Sample Populations The first concept which will be kept in mind with the design is based on geographic location. In the UK, there are several regions and areas that are designated as cultural quarters, specifically which is a part of the growing urban culture that is in the region (Montgomery, 2004). There are also other regions which are not as focused on implementing new cultures and ideologies, which build a different outlook on how many approaches the ideology of rehearsal studios and whether this should be implemented. Examining both aspects of the need for a rehearsal studio will then assist in creating a different outlook for the implementation of the studio. A second aspect to consider with the sample population is based on the target market of who would use a rehearsal studio. The main approach is toward musicians, engineers and producers that would be interested in having a main area for creating music. There can also be applications for other types of art, such as a rehearsal space for dance, as well. With these considerations, is also an understanding that the concept is based on creating communities through the use of space. This is combined with the alternative, which is available with online and remote communities and technology tools used for creating music or working with the fine arts (Trueman, 2007). From this perspective, there is the need to create a rehearsal studio that define what the studio can be used for and how it should be approached in terms of community building. Quantitative Method The first method which will be used will combine the sample populations with an overall examination of the viability of starting a studio. This will begin with creating an understanding of the finances that are involved with a rehearsal studio. The quantitative method will examine the budgets of rehearsal studios that are already in place in the UK, including ones based on urban culture and others that are in both city settings and remote areas. The examination will include: 1. Start up costs of the studio. 2. Maintenance costs of the studio. 3. Amount of income from the space. 4. Years in operation. 5. Profit and loss over each year and whether this has grown. 6. Main individuals using the rehearsal space. The comparison of these different factors will show examples of how much investment has to be made with the rehearsal studio as

Green Revolution Essay Example for Free

Green Revolution Essay Interaction between humans and the environment has always had a great importance in the development of humankind; according to Marx, what differentiates humans from other animals is the fact that humans can transform their surroundings to suit their needs, through labor. The Green Revolution is not the exception to that. In times of need the human being manipulated its environment to be suitable for its development, however, the question lingers, how efficient was it, how positive? The Green Revolution, from 1945 to the present, was motivated by the need to increase the production of food to supply for the increasing demand as population grew, to promote national self-sustainability in terms of food. However, during that period the effect of the Revolution have been detrimental to the environment and society: they have damaged agricultural diversity and heritage, damaged the lands, and put at risk food security; also, they have widened the gap between the very rich and the very poor, monopolizing the food industry. The Green Revolution originated after an urgent need to promote food security with a growing trend in global population, as a way to promote self-sustainability and independence. As it is clear in the report given by the Food and Agriculture Organization (DOC 2), in the period ranging from around 1929 (great depression) and 1945 (end of World War II) the global food supply index was below the world population. What this means is that there was literally not enough food being produced world wide to feed the world population. This struggle of human kind to stay afloat in supplying the minimum needs for survival meant that a change needed to occur. The answer, as Dr. Norman Borlaug stated in his Nobel Lecture (DOC 4) was not simply planting more in the developing nations, since the lands in those areas were â€Å"tired, worn out, depleted of plant nutrients†¦Ã¢â‚¬  Clearly, what the document refers is that a new, more effective way of growing food had to be developed. In fact, Dr. Borlaug states that the priority of the developments of the green revolution concentrated in the millions that were lurked by hunger, a large problematic that clearly was under the spotlight. As a proof that the world was prioritizing the deficient food supply is the statement given by President Harry Truman (DOC 3). President Truman was the leader of the most powerful nation in the world at the time, the one with the largest technological developments, and his word was the one that would set the course of the world. This particular speech is vital, since it is the inaugural speech, where he was to set the priorities of the government and address the world with what the United States had as a course for the future. In this speech, he clearly refers to the shocking figure that â€Å"more than half the people of the world are living in conditions approaching misery† and says that the United States will help provide â€Å"technical knowledge†¦ to produce more food† In the speech President Truman refers often to liberty, thus meaning that self-sustainability will provide freedom. This speech is the perfect example, the jewel of the trend that the world was seeing with regard to prioritizing food. The mention of â€Å"technical knowledge† is vital in the construction of the green revolution as a response to the lack of food, with technological developments in the agricultural field. Some have said that the Green Revolution has been a success in improving the food industry, and improving living conditions for everyone; nevertheless the numbers today reflect a mediocre success. Indian minister for food and agriculture (1964-1967) states in an interview (DOC 5) that the farmers of the state of Punjab competed to use the technology that was introduced by the green revolution the best. It is stated with a positive connotation, as to refer to the great feats of Punjab. This seems very positive, however, the most likely reason for this to have occurred is the fact that multinational corporations were kicking them out of the market and they were forced into utilizing the technology that those same corporations were imposing on them. If this were true, which it most likely is, as it has happened in many places around the world, it would discredit the great success that the Green Revolution supposedly is. Furthermore, the claim is that the Green Revolution has brought prosperity, however, to whom, to the ones that were rich already? A perfect example of this negative impact of the Green Revolution is the conversation between Mrs. Dula and the United Nations official (DOC 6), which gives a not very realistic perspective of the impact of the green Revolution and is concentrated exclusively in the sector of the very rich. This document is indeed quite revealing, as the speaker is an aristocratic woman of Mexico, probably a housewife who sees the world through the optic of his husband, a man who earns a salary if the revolution which he works for is successful; in fact, she is most likely part of one of the clubs she talks about herself. The occasion of this statement is a simple conversation with a UN official, probably at some sort of a social event, where the high class is all joined together, with perfectly slanted people who are not really analyzing the global impact of the Green Revolution. This document gives a crystal clear proof of how much the Green Revolution has made the â€Å"rich Mexican farmers† richer probably at the expense of making the poor laborers, poorer, however, this document presents only one, very bright point of view to sell the revolution. With regards to India once again, socially, they sell the idea of improvement, like in the report of the State of Punjab (DOC 9) where it says that the Green Revolution has seen with it the â€Å"emergence of middle and rich peasants† a very undesirable euphemism to conceal the actual situation. This document seems to give a perspective of social growth and development, of a population going for education, yet once again, it seems very idealistic in its tone, when in reality India has totally different conditions. With regards to that, India has one of the largest Gini index’s in the world, meaning a huge social inequality, and has one of the smallest middle classes in the world, which has diminished even more throughout the years, meaning that in reality, India may have had a somewhat positive year, but the general trend is of a very pronounced downturn in social progress, all related to the Green Revolution which is destroying the small farmers. The Green Revolution, in truth has brought more ill than it has brought good, in the environmental and social aspects. Regarding environmental harm, the FAO Wheat Yield report (DOC 1) is very good in demonstrating the introduction of massive scale crops that the Green Revolution brings forth with it. The introduction of these crops damages the lands since they are not prone to such production. The graphs show that in both Mexico and India the crop yields were extremely irregular, and as time passed they have become even more, this is due to the fact that they are not proper to those areas and its planting is something totally synthetic and with complete disrespect towards the natural balance. The article by Dr. Vandana Shiva (DOC 8) reveals how much damage the crops, especially Genetically Modified Organisms; do to the land they are planted in. The â€Å"reduced genetic diversity, increased vulnerability to pests, soil erosion, water shortages†¦Ã¢â‚¬  are effect that will leave marked the land for a long time, as Dr. Shiva states, and are a threat to future generations, which will have totally barren land where it will be impossible to plant food. Dr. Shiva also refers to the social problematic that the Green Revolution is planting alongside its seeds. For instance the fight for water to provide irrigation, previously not needed in India, has lead to â€Å"conflict and violence† and as it has become a worldwide trend, the career for water dominance is â€Å"leading to both local and interstate water conflicts. † This clearly shows how disadvantageous the spread of the Green Revolution has been, since it has brought unmeasured changes that have not been made responsibly, but rather abruptly, causing enormous damage. Dr. Shiva is an Indian Physicist, and being from India she probably has had a very direct contact with the Green Revolution, considering that one of its birthplaces was in fact the State of Punjab. In this occasion she is writing for the Ecologist magazine, a publication read by people with primary interest in the environmental issues, including organization leaders and maybe politicians who will probably get concerned, especially due to the tone of annoyance and hatred that she employs in the article. Expanding on social implications, the Guatemalan National Coordinating Committee of Indigenous peasants (DOC 10) gives a different perspective. Although it may sound somewhat as mysticism from indigenous people, saying that they have contaminated the seeds is not a joke, considering the hormones that can be found in GMO plantations. This also acknowledges a vital issue, the loss of diversity and heritage that society is killing with the systematic Green Revolution trends, like the Mayan traditions, which have been present for â€Å"five thousand years. † Furthermore, the social disaster does not stop there, but stumbles over women, which according to the FAO Newsletter (DOC 7) have been forced to change their job. In this case the implications have made woman, traditionally in other roles, have even less opportunities to succeed, as the increased need for cash income made the woman be forced to work. This implies a social catastrophe since it denies the right of woman to equal opportunities, which are stripped off with the Green Revolution, which makes them simply one more laborer forced to work. Additional to the information presented in the documents it would be vital to contain the point of view of a small scale male farmer that has to compete with the multinational corporations, which have been installed after the start of the Green Revolution circa 1945. This would be important since it would show the first hand effects of the monopolies that the Green Revolution has brought, with regards to the social impact it has made, and whether that impact is positive or negative. As discussed throughout the essay, the Green Revolution, which has lasted from 1945 until the present day, was originated with a need to secure food production in a starving world. However its effects were not so positive, since today many starve, and the Green Revolution has damaged the environment and widened the gap between the social classes. The setup of crops that have give no benefit to the places in which they are grown, with complete disregard to the ecological balance that was being destroyed have caused issues ranging from soil erosion to water shortages and crops with pest vulnerability. The Green Revolution has also made the rich farmers richer at the cost of the poor being poorer, since the costs of the new technologies are not easily accessible, but the yields that they provide take the small farmers out of business. In general, although certain governments sponsor the Green Revolution and make it seem positive, it has brought about large changes in the way humans interact with the environment, with a generalized destruction of it to get short-term solutions to the problem of food shortages.

A Report Of The Nervous System

A Report Of The Nervous System The report are divided into two parts. first we will be talking about the Organization of the Nervous System, that includes the Peripheral Nervous system, and the Central Nervous system, then we will move on to the Brain and Behavior part, where we will start to talk about the brain and listing down the three major regions of the brains, and how each brain has its own functions different than the other regions, even though they are all located in the brain. In this report, you will find information about organs or nervous systems found in the human body, beginning with the definitions, describing its structure and functions in the body, illnesses or disorders that affects that part in the body. Part 1: Organization of Nervous System: Introduction: The Nervous System is a world in itself, weve learned only the little tidbits of its secrets, but there are many of what we still do not know, and in this section of the report, we will try to identify the anatomic configuration of the nervous system, its division and branches, and the function of each part of it, and the problems resulting in every part. The communication in the nervous system is essential to behavior. If youve wondered how you are aware of the elements in the environment surrounding you, you hear with your ears and see with your eyes, and be aware of many things by touching and smelling and tasting, following this awareness a response coming from you, so you move or talk or touch and hold things. You receive the influential in a very short time, and this can be done by the nervous system, moreover, the nervous system controls the other organs that works voluntary such as holding up things or the involuntary such as heartbeat rate. Nervous System chart Nervous system sections: The nervous system are divided into two main divisions: Peripheral Nervous System. Central Nervous System CNS. (the brain and spinal cord) First comes first. We will start with the peripheral nervous system. The peripheral nervous system: is made up of all those nerves that lie outside the brain and spinal cord. Nerves are bundled of neuron fibers (axons) that are routed together in the peripheral nervous system. The peripheral nervous system are made off nerves and neurons that sends and receive information to and from the brain. The peripheral nervous system are subdivided into two parts, the autonomic nervous system and somatic nervous system. Let us have a look at the Autonomic Nervous System. Autonomic Nervous System: The autonomic nervous system (ANS) is made up of nerves that connect to the heart, blood vessels, smooth muscles, and glands. The autonomic nervous system function is to maintain the internal environment of the human body in a stable state, sometimes called homeostasis. Maintaining and balancing the internal environment by controlling visceral organ functions that people dont normally think about. like heart rate, blood pressure, digestion and perspiration. The Autonomic nervous system mobilized bodily resources in times of need. Just as its name, this nervous system works automatically, without the control or conscious of the individuals, these which we do not directly control are like closing your eyes, the increase of heartbeat, sweat or produce saliva by stimulating our salivary glands. For example, right when you first experience fear, the Autonomic nervous system will start and work on to control the involuntary, visceral functions that are difficult to control consciously. How it does it work: when you see something frightening or threatening your life, and happens to throw fear into you, your heartbeat rate will rise, sweating, pupil dilation, goose bumps and increased respiration. Even thought the Autonomic nervous system works unconsciously, we can sometimes be aware that our heartbeat rate has increased. One of the first psychologists to study this reaction is Walter Cannon (1932). He referred it to as the fight-or-light response reaction. Cannon monitored this response from cats after confronting them with dogs. From his observation on the cats response, he concluded that what prepares generally any organisms physiologically for attacking (fight) or fleeing from (flight) the enemy is the response to a threat, or when faced to danger. Illness and diseases affecting the Autonomic Nervous System: There are diseases and illnesses affecting the autonomic nervous system, causing a disorder in the system, which this disorder effects the controlling of the heartbeat rate and blood pressure of the body that can lead into causing serious problems to the patient, some of these disorders can be life-threatening when they affect the breathing or heart function of the patient. Some of these diseases are Diabetes, Alcoholism and Parkinsons disease. Disorders made by the diseases can either affect the whole system, or a part of it. The Sympathetic and Parasympathetic Divisions: The Autonomic Nervous System are subdivided into the Sympathetic division and the Parasympathetic division. The Sympathetic Division: The sympathetic division is the branch of the autonomic nervous system that mobilizes the bodys resources for emergencies. As we stated before, the sympathetic nervous system is a sub part of the Autonomic Nervous System. This system is responsible for controlling functions that mobilize the bodys resources under stress, such as the fight or flight response, and the other energy generation forms as well. Not only the sympathetic nervous system prepares the body when faced with stress or emergencies, but it also serves other vital purposes. Example, if you stand up after being setting down for a long period of time, your blood pressure will raise, else you may fall unconscious. The sympathetic nervous system also works in increasing your heartbeat rate and perspiration during exercises. Diseases affecting the Sympathetic nervous system: A disease affecting the sympathetic nervous system known as reflex sympathetic dystrophy syndrome (RSDS). The signs of this dieses are the heightened sensitivity to heat and cold, excessive sweating, and limbs being warm to the touch. The causes of this dieses are not confirmed, but its seems to be associated with some forms of nerve injury. The Parasympathetic Division: Like the sympathetic, it is a sub part of the Autonomic Nervous System, and most what the parasympathetic division controls are visceral and involuntary organs, such as breathing and blood pressure and heartbeat rate, But it differ from the sympathetic division in its activities. The parasympathetic division are responsible in controlling the body organs when in an relaxed or normal state. Some of its activities when the conditions are met, and those condition can be met when the person are calmed and relaxed, is reducing the heartbeat rate, slow down the respiratory rate, increases perspiration and salivation and smaller eye pupils. The Sympathetic and Parasympathetic divisions activities are the opposite of each other, but they work together to maintain stability in the body when a certain external condition are met and calls for the division that are responsible to act in such situation. Much like an automobile accelerators and brakes. The Central Nervous System: The Central Nervous System are responsible of controlling the whole body, regulating the functions of the body. The Central Nervous System are the control center of the body. The central nervous system (CNS) consists of the brain and the spinal cord. The Central Nervous system lies within the skull and the spinal column, protected by enclosing sheaths known as the meninges, additionally, the central nervous system is covered by the cerebrospinal fluid. The cerebrospinal fluid (CSF) nourishes the brain and provides a protective cushion for it. Ventricles are the hollow cavities in the brain that are filled with CSF. Diseases affecting the central nervous system: diseases and infections of the central nervous system are many, some of these diseases are Alzheimers disease. The Spinal Cord and The Brain: So we know now that the Central Nervous System consists of two things, the brain and the spinal cord. Let us have a look at these two organs: The Spinal Cord: Basically, the spinal cord is an extension of the brain. The spinal cord are located at the back of the body and are enclosed by the backbone Vertebral column, running from the base of the brain to below the waist, and are covered by the meninges. The spinal cord connects the brain to the whole body through the peripheral nervous system, conducting sensory information to the brain from the peripheral nervous system, And from the brain, the spinal cord works on conducting motor information to the glands, skeletal, cardiac, and smooth muscles. The Spinal cord also serves as a minor reflex center. The spinal cord consist of bundles of axons, and these axons carry out the commands from the brain to the peripheral nerves, that relays sensation from the periphery of the body to the brain. Spinal Cord Injury: Injury to the spinal cord can damage it, causing a partial or full paralysis to the body. Injury can be a result from a car accident or from a serious fall, or any other form of injury that damages the spinal cord, like a gunshot. The Brain: The brain is the part that of the central nervous system that fills the upper part of the brain. The brain is enclosed by the skull. The average weighs of the brain are 1.3 kg, three pounds, and contains billions of nerve cells that links and relays information in and outside the body, Such as coordinating the body actions and movements, talking, thinking, remembering, planning, creating and dreaming. The brain are covered by the meninges, moreover, the brain contains bundles of axons, that works on receiving sensory information from its own nerves, as well as from the spinal cord. Brain Injury: Injuries to the brain can be the result of a car accident, or any other form of damage or hit directed to the head. Childrens or infants can possibly get a brain injury if shaken violently. Part 2: The Brain and Behavior Introduction: The Brain, and how it controls our behavior. All of the body movements, thinking, dreaming, talking, remembering, feeling, and any other actions, are controlled by the brain. The Brain is the control room of your body. From the brain, commands are issued and sent to the whole body, and these commands are carried out, in and out by the nerves. In this part of the report, we will shed some light on the brain, and how every region in the brain has functions different than the other regions, even though they are located in the same organ. The Three Regions of the Brain: The brain has three regions, The Hindbrain, the Midbrain and the forebrain. The location of the three regions are the same, but differ in function and size of region. The Forebrain is taking the largest portion of the brain, then comes the Hindbrain, and smallest is the Midbrain. Structure and Areas of the Brain: The Hindbrain: The hindbrain includes the cerebellum and two structures found in the lower part of the brainstem: the medulla and the pons. The controlling of essential body function and process, such as heartbeat rate and respiration, is the Hindbrain responsibility. An important part of the Hindbrain, the brainstem, controls functions such as swallowing and breathing, and any other critical functions that affect the life of the living being. The Medulla are attached to the spinal cord, controls unconscious vital functions, such as blood pressure, heartbeat rate, swallowing, breathing and coughing. The Medulla works without relying on the thoughts of the person, It works by itself. The pons, sometimes called the Bridge, because of its form of structure which looks like a bridge connecting between the medulla and the cerebellum. From its structure form, we can know that it works on sending signals to and from the cerebellum and the cerebrum, a part located in the forebrain. The Pons contains clusters of cell bodies that helps in controlling movements and sleep. The Cerebellum, which means Little brain in Latin, Is a large and a folded structure located rear lower portion of the brain. The role of the cerebellum is providing feedback and fine-tuning for motor output. The cerebellum controls movements and smoothing them up, such as when you bring up your hand and smoothly bring your finger to a stop on your nose, and how you walk, and every action or movement that people make without any thinking about them or concentration, are coordinated by the cerebellum. The Midbrain: The midbrain is the segment of the brainstem that lies between the hindbrain and the forebrain. The Midbrain, The smallest region of the brain regions, are responsible for visual and auditory and motor system information station. motor and sensory functions are directly controlled by the midbrain. An Important system of dopamine- releasing neurons, which originates in the midbrain, projects into various high centers of the brain. Conscious, voluntary movements has dopamine system are involved in their performance. Degeneration or decline in dopamine synthesis is associated with Parkinsons disease. The reticular formation, which are located at the central core of the brainstem, is the structure that runs through the hindbrain and the midbrain. The reticular formation contribute in the modulate of breathing, reflexes and pain perception. The Forebrain: The forebrain is the largest and most complex region of the brain, encompassing a verity of structures, including the thalamus, hypothalamus, limbic system, and cerebrum. The three structures, the Thalamus, hypothalamus and the limbic system, form the core of the forebrain. The location of the three structures are near the top of the brainstem. The cerebrum sits above the three structures. The cerebral cortex, the outer layer of the brain, is the wrinkled surface of the cerebrum. So now we know that the Forebrain, which takes the biggest portion of the brain, and the biggest of the three regions, consists of four structures, the Thalamus, Hypothalamus, Limbic system and cerebrum. Let us have a quick look on each structure and its activities and functions. The Thalamus: The thalamus is a structure in the forebrain through which all sensory information (except smell) must pass to get to the cerebral cortex. The Thalamus which is located at the top of the brainstem, is responsible for relaying sensory information to a particular part of the cortex, and regulating motor control. It also works on receiving information and signals from various brain areas, such as auditory, visual sensory, and samotosensory signals. The Hypothalamus: The hypothalamus is a structure found near the base of the forebrain that is involved in the regulation of basic biological needs.

Optical Fiber Sensors and Conventional Sensors

Optical Fiber Sensors and Conventional Sensors ABSTRACT This study deals with the comparison of the two types of sensors which are widely used in civil engineering, namely, conventional sensors and optical fiber sensors. Temperature and displacement are the two principal parameters which are measured with the aid of Fiber optic sensors. Bragg Grating, Interferometric, Intensity Sensors, and optical time domain reflectometry (OTDR) are some of the techniques which are used for sensing. In this study, various case studies have been undertaken and have been analyzed. With the aid of these case studies, a detailed analysis and comparison of the sensors is carried out. Chapter 1: INTRODUCTION In the last two decades, the world has witnessed a revolution in the sectors of optoelectronics and fiber optic communications. Various products such as laser printers and bar code scanners which have become a part of our daily usage, are a result of this technical revolution only. The reasons for the phenomenal growth of the fiber optics are many. The most conspicuous reason being the ability of the fiber optics to provide high performance and highly reliable communication links and that too at a very low bandwidth cost. As we see that optoelectronic and fiber communications industry has progressed a lot, and along with these industries fiber optic sensors have also benefited a lot from these developments. Due to the mass production in these industries, availability of fiber optic sensors at a low cost has been made possible in recent years. With their availability at affordable costs, fiber optic sensors have been able to enter the domain which was otherwise being ruled by the trad itional sensors. In recent years, the demand for the development of new materials to strengthen, upgrade and retrofit existing aged and deteriorated concrete structures has increased rapidly. The continuing deterioration and functional deficiency of existing civil infrastructure elements represents one of the most significance challenges facing the worlds construction and civil engineers. Deficiencies in existing concrete structures caused by initial flawed design due to insufficient detailing at the time of construction, aggressive chemical attacks and ageing of structural elements enhance an urgent need of finding an effective means to improve the performance of these structures without additionally increasing the overall weight, maintenance cost and time. In the last 50 years, a large number of civil concrete structures have been built; many of these structures, particularly in off-shore regions have now deteriorated and require repair in a short period of time. Moreover, the increase of traffic volume and population in many developing countries is causing the demand to upgrade existing concrete structures to increase. The damage of reinforced concrete (RC) structures through reinforcement corrosion and residual capacity are the most important issues that concern engineers. These problems occur not only in constructed concrete structures but also in structures strengthened by externally bonded steel reinforcements. In the past, the external steel plate bonding method has been used to improve strength in the tensile region of concrete structures with an epoxy adhesive and has proved to be successful over a period of 20 years. However, the use of steel reinforced plates and bars has its disadvantages including high corrosion rates, which could adversely affect the bond strength and cause surface spalling of the concrete, due to volumetric change in the corroded steel reinforcements. Since the early 1980s, fibre-reinforced plastic (FRP) materials have been used as a replacement for conventional steel materials for concrete strengthening applications. In recent years, the interest in utilizing FRP materials in the civil concrete industry in forms of rods, plates, grid and jacket has grown increasingly. When an FRP plate with high tensile strength properties bonds on the concrete surface, it can strengthen the structure with minimum changes to its weight and dimensions. FRP offers substantial improvement in solving many practical problems that conventional materials cannot solve to provide a satisfactory service life of the structure. Unlike the conventional steel materials, FRP is corrosion resistant. The beneficial characteristics of using the FRP in concrete construction include its high strength-to-weight ratio, low labour requirement, ease of application, reduced traffic interruption during repair, cost reductions in both transportation and in situ maintenance for a long-term strategy. Its high damping characteristic also attracts more structural engineers to use these materials for seismic retrofitting. Due to the increasing use of FRP-plate bonding techniques in strengthening civil concrete structures, the interest in finding a suitable means of monitoring the structural health conditions of these strengthened structures has therefore increased substantially. Since strengthened structures are covered by the FRP plates, the mechani cal properties of the concrete may not be measured or detected easily through conventional nondestructive evaluation (NDE) methods, such as strain measurements using surface mounted strain gauges or extensometers, radiography, thermography and acoustic emission methods, particularly in areas with microcracks and debonds underneath the externally-bonded plate. Besides, these structural inspection technologies, in certain cases, require special surface preparations or a high degree of flatness in the concrete surface. These requirements may be hard to achieve, particularly for an area that is exposed to a harsh environment. During the 1990s, a multi-disciplinary field of engineering known as ‘Smart Structures has developed as one of the most important research topics in the field.The structure is formed by a marriage of engineering materials with structurally-integrated sensor systems. The system is capable of assessing damage and warning of impending weakness in the structural integrity of the structure. Fibre-optic sensor technology is a most attractive device currently used in the aerospace and aircraft industry for on-line monitoring of large-scale FRP structures. The development of distributed fibreoptic sensors, which provides information on a large number of continuously distribution parameters such as strain and temperature is of great interest in most engineering applications.11,12 The sensors are embedded into a structure to form a novel self-strainmonitoring system, i.e. the system can self-detect its health status and send response signals to operators during any marginal situation during service. The embedding sensor, due to its extremely small physical size, can provide the information to a high accuracy and resolution without influencing the dimension and mechanical properties of the structure. Fibre-optic sensors present a number of advantages over the conventional strain measuring devices: (a) providing an absolute measurement that is sensitive to fluctuation in irradiance of the illuminating source; (b) enabling the measurement of the strain in different locations in only one single optical fibre by using multiplexing techniques;(c) having a low manufacturing cost for mass production; and (d) its ability to be embedded inside a structure without influencing the mechanical properties of the host material. A new development of ‘Smart materials and structures was driven by a strong demand for high performance over recent years. A system integrated into structures and being able to monitor its hosts physical and mechanical properties such as temperature and strain, during service is appreciated as a ‘Smart structural health monitoring system. The term smart material and structure is widely used to describe the unique marriage of material and structural engineering by using fibre-optic sensors and actuation control technology. The smart structure is constructed of materials that can continuously monitor their own mechanical and physical properties, and thereby, be capable of assessing damage and warning of impending weakness in structural integrity. This design concept results in improved safety and economic concerns regarding the weight saving and avoidance of over-designing of the structure in the long run. In Fig. 1, a schematic illustration of the structures possibilities created by the confluence of the four disciplines is shown. In the figure, a structure invested with actuating, sensing and neutral networking systems to form a new class of adaptive structures is shown. A structure with integrated sensor or actuator systems i s able to provide a self-structural health monitoring or actuating response, respectively. If both systems are integrated together into a structure, the sensor and actuators can act as nervous and muscular systems, like a human body, to sense the conditions such as mechanical strain and temperature of the structure (a smart structure) and to provide control of such changes of stiffness, shape and vibration mode (a controlled structure). The combination of these two systems into one structure is called a ‘Smart adaptive structure. This structure with a built-in neural networking system, like a brain, is then able to self evaluate the conditions, which are based on changes of structural parameters, thermal conditions and ambient environments to give an appropriate mechanical adjustment. This structure is commonly called an ‘Intelligent adaptive structure. 1.1 BACKGROUND OF THE STUDY There has been an unprecedented development in the fields of optoelectronics and fiber optic communications. This in turn, has brought about a revolution in the sectors of telecommunication and various other industries. This has been made possible with the aid of high performance and reliable telecommunication links which have low bandwidth cost. Optical fibers have numerous advantages and some disadvantages. The advantages include their small size, resistance to electromagnetic interference and high sensitivity. On the other hand, some of its disadvantages are their high cost and unfamiliarity to the end user. But its great advantages completely overshadow its minor disadvantages. So, in this study an attempt is being made to compare the modern age fiber optic sensors with the conventional sensors. Also, with the aid of the case studies, the impact of fiber optic sensor technology on monitoring of civil structures is studied (McKinley and Boswell 2002). 1.2 PROBLEM STATEMENT In the past various kinds of sensors have been used in civil engineering for measuring temperature, pressure, stress, strain etc. And as the optical fiber sensors spread their wings, the civil engineering is bound to gain a lot from these modern sensors. Presently, there exist a number of problems with the existing civil infrastructures. These civil infrastructures such as bridges etc. have a pretty long service period which may amount to several decades or maybe even hundred years. Thus, during this time period, these structures suffer from corrosion, fatigue and extreme loading. Since concrete is used mostly in these civil infrastructures, it degradation is a major issue all over the world. The amount of degradation and the time when the degradation starts depends on various factors and is inevitable and unavoidable. Thus, in order to keep these civil structures in good condition, it becomes necessary that their condition be monitored and adequate steps be taken. Thus, we need sensors which can monitor these structures throughout the life of these structures. Thus, in this study the impact of fiber optic sensors is studied on civil structures. 1.3 OBJECTIVES There are a few objectives that are planned to be achieved at the end of this project, these are: A general discussion on the present state of structural monitoring and the need of fiber optic sensors in this field A general study on Comparison between Conventional Sensors and Optical Fiber Sensors Review of Case Studies on Fiber Optic Sensors application in Civil Engineering Structures 1.4 WORK PLAN Discussion, reading and observation Problem identification through reading, discussion and observation of the area studied Understand and identify the background of problem Studying feasibility and needs to carry out the investigation Identification of the Title for the project Identify the aim, objective and scope of the project Literature Review Understanding the background of the problem Understanding the history of the sensor technology in structural monitoring Carrying out literature survey on generic technologies of sensors for concrete structures Identify the types of sensor involved in monitoring the structural in civil engineering Identify the technique used and the working principle for each type of sensors (in particular optical fiber sensors) Case Study Choose the relevant and related case study for discussion Describe important aspects of case study Analyze the use of sensors in the case study Discussion, Conclusion and Recommendations Discuss the similarities and differences Discuss the technical facets of sensor application Draw the overall conclusion for this project Give some recommendation for future Chapter 2: APPLICATIONS These days the fiber optic sensors are being used for a variety of applications, the most prominent of them being: Measurement of rotation and acceleration of bodies Measurement of electric and magnetic fields Measurement of temperature and pressure of bodies Measurement of acoustics and vibrations of various bodies Measurement of strain, viscosity and chemical properties of materials Measurement of surface condition and tactile sensing Measurement of sound , speed and proximity of bodies Determination of color and weight of different objects Measurement of linear and angular positions and this is widely utilized in civil engineering structures 2.1 ADVANTAGES OF FIBER OPTIC SENSORS Like with any other technology, there are both advantages and disadvantages using fiber optic sensors. The prominent advantages being: Fiber optic sensors are lightweight and this is of great importance in case of engineered structures Fiber optic sensors are of smaller size as compared to the traditional sensors Also, fiber optic sensors consume less power as compared to the traditional sensors Along with this, these sensors show high resistance to electromagnetic interference as compared to the traditional sensors On top of this, fiber optic sensors have enjoy high bandwidth and high sensitivity as compared to their traditional counterparts Fiber optic sensors are usually embedded in objects and due to this, these sensors can gain access to areas which till date remain inaccessible with the aid of traditional sensors Also, these sensors are accurate over a greater dynamic range as compared to the traditional sensors Fiber optic sensors are also capable of being multiplexed which again is a further advantage over their traditional counterparts Also, fiber optic sensors are capable of distributed measurements which gives them an edge over and above the traditional sensors Last but not the least, they also show greater environmental ruggedness as compared to the traditional sensors 2.2 DISADVANTAGES OF FIBER OPTIC SENSORS But all this is just one side of the coin. Though on seeing these advantages, it might appear that fiber optic sensors are way too advanced as compared to the traditional ones, but it is not exactly true. These fiber optic sensors also have some disadvantages due to which their advancement in todays world has been somewhat curtailed. The major disadvantages of fiber optic sensors are: Fiber optic sensors are quite costly as compared to the traditional sensors. Due to this, many people still consider traditional sensors to be a better option in cases where cost is a major consideration. Secondly, these sensors have come into prominence only in the last two decades. Due to this, people appear to be somewhat less educated regarding their usage and operations. And this unfamiliarity with the usage of these sensors, has proved to be a major hurdle in being able to capture the whole market. Also, these sensors are considered to be more fragile as compared to the traditional sensors which raises a question over their adaptability in extreme conditions Also with the fiber optic sensors there exists the inherit ingress/egress difficulty Fiber optic sensors usually have a non-linear output which is a cause for concern in some applications From the above discussion, we can see that as is the case with any other new technology, there are both merits and demerits of fiber optic sensors. But, what is worth considering here is that the advantages of this technology are much more than its disadvantages and are able to outweigh them. Also, from the demerits which are mentioned here, it is clear that these demerits are bound to wither away as this technology develops and gains more prominence. 2.3 APPLICATIONS IN CIVIL ENGINEERING Now we come to the discussion of the need and applications of the fiber optic sensors in the field of civil engineering structures. The monitoring of civil structures has a great significance in todays world. Today, we not only need to construct reliable and strong civil structures, but we also need to monitor these structures in order to ensure their proper functioning and their safety. Also, with the aid of the monitoring of various parameters of the structures, we can get knowledge about state of the building and by using this data, we can in turn plan the maintenance schedule for the structure (Mckinley, 2000). Also, this data can give us an insight into the real behavior of the structure and can thus take make important decisions regarding the optimization of similar structures which are to b e constructed in future. The maintenance of the structures can be approached in one of the two ways, namely: Material point of view- In this approach, monitoring is concentrated on local properties of the materials which are used in the construction. In this approach, we observe the behavior of the construction materials under the conditions of load, temperature etc. In this approach, short base length sensors are usually utilized. Also, it is possible to get the information about the whole structure with the aid of extrapolation of the data obtained from these sensors. Structural point of view- In this approach of measurement, the structure is viewed from a geometrical point of view. In this approach, long gauge length sensors appear to be the ideal choice. In this approach, we will be able to detect material degradation only if this material degradation has an impact on the form of the structure. In the recent years most of the research work which has been carried out in field of optic sensors has been in the field of material monitoring rather than structural monitoring. It is also worth mentioning here that, more sensors are required in the case of material monitoring as compared to structural monitoring. We know that civil engineering requires sensors that can be embedded in the concrete, mortars, steel, rocks, soil, road pavements etc. and can measure various parameters reliably. Also what should be taken into account is that these sensors should be easy to install and should not hamper the construction work or the properties of the structure in any derogatory manner. Also, it is common knowledge that at the sites of civil engineering, there exist the unavoidable conditions of dust, pollution, electromagnetic disturbances and of unskilled labor. Thus, the sensors to be used in these cases need to be rugged, should be inert to harsh environment conditions and should be easy to install and their installation could be carried out by unskilled labor. Along with all these things, it is imperative that these sensors are able to survive a period of at least ten years so that they can allow for a constant monitoring of the aging of the structure. Thus, we see that the fiber optic sensors ca n prove to be quite handful in civil engineering applications and structures. In the past various kinds of sensors have been used in civil engineering for measuring temperature, pressure, stress, strain etc. And as the optical fiber sensors spread their wings, the civil engineering is bound to gain a lot from these modern sensors (Vurpillot et al., 1998). Chapter 3: LITERATURE REVIEW ON FIBER OPTIC SENSORS Fiber optic sensors are of many kinds, but they can be broadly classified into two types, namely, extrinsic fiber optic sensors and intrinsic fiber optic sensors. There is a great deal of difference between these two types of fiber optic sensors and this difference is discussed in detail below. 3.1 EXTRINSIC FIBER OPTIC SENSORS This type of fiber optic sensor is also known as hybrid fiber optic sensor. As we can see in the figure above that there is a black box and an input fiber enters into this black box. And from this input fiber, information is impressed upon light beam. There can be various ways by which the information can be impressed upon. Usually this information is impressed upon the light beam in terms of frequency or polarization. This light which then posses the information is carried away by the optical fiber. The optical fiber now goes to an electronic processor. (Vurpillot et al., 1998) Here, in the electronic processor the information which is brought along by the fiber is processed. Though we can have separate input fiber and output fiber, but in some cases it is preferred to have the same fiber as the input fiber and the output fiber. 3.2 INTRINSIC FIBER OPTIC SENSORS The other type of optic fiber sensors is the intrinsic fiber sensors. An example of an intrinsic fiber sensor is shown in the figure below. The working of the intrinsic fiber sensors is somewhat different from the working of the extrinsic fiber sensors. In the intrinsic fiber sensors, the light beam is modulated and we rely on this modulation in the fiber in order to carry out the measurement. In the figure above, we can see an intrinsic fiber sensor or what is also known as all fiber sensor. 3.3 INTENSITY BASED FIBER OPTIC SENSORS While there exist various kinds of fiber optic sensors today, but the most common of these sensors is the hybrid type fiber optic sensor which depends upon intensity modulation in order to carry out the measurements (Zako et al., 1995) In the figure below, we can see a vibration sensor. In this vibration sensor, there exist two optical fibers. The functioning of this fiber optic sensor is quite simple. In this fiber optic sensor, light enters from one side. And when this light exits from the other side, it exits in the form of a cone and the angle of this cone depends on two parameters. The two parameters upon which the angle of this cone depends are: Firstly, it depends on the index of refraction of the core Secondly, it depends on the cladding of the optical fiber Also, the amount of light captured by the second optic fiber depends on a number of factors. The prominent factors on which the amount of light captured depend are: It depends on the acceptance angle It also depends on the distance â€Å"d† between the optical fibers Another type of fiber optic sensor is the flexible mounted mirror sensor. The important characteristics of this sensor are: In this case, a mirror is mounted which is used to respond to external parameters such as pressure. The modulation in intensity is caused the shifts in the mirror position. These sensors are used in a variety of applications such as door closures. In a door closure, a reflective strip is used. These sensors are used to measure small variations and displacements 3.4 LINEAR POSITION SENSORS In todays world, linear position sensors have become widely applicable. They are being used for various purposes (Zako et al., 1995). In many of the linear positioning sensors, wavelength division multiplexing is used. An illustration of the linear position sensor is shown in the figure below. The various components of this linear position sensor are: It consists of a broadband light source It consists of various detectors as shown in the figure above It also consists of wavelength division multiplexing element which acts as the principal component of this instrument. It also consists of an encoder card In the example above, a broadband light source is utilized. The light from this broadband source is carried to a wavelength division multiplexing system with the aid of a single optic fiber. The wavelength division multiplexing system is used to determine the linear position. Another linear motion sensing method which is very widely used today and is quite similar to the method discussed above is known as the time division multiplexing method. This method is illustrated with the aid of a figure shown below. In this method instead of a broadband light source a light pulse is used. Here, the combination of the returned signals takes place. As a result of this combination of the returned signals, the net signal which is produced moves onto the position of the encoder card. The main areas in which these intensity based fiber optic sensors have found application are: In commercial aircrafts In military aircrafts In these applications these modern sensors have performed quite well and are at par with the performance of the conventional sensors. But, because of the various advantages these sensors enjoy over and above the conventional sensors, these modern sensors are bound to replace the conventional sensors in the years to come. 3.5 LIQUID LEVEL SENSORS This is another type of intensity based fiber optic sensor. In the functioning of this sensor, the principle of total internal reflection is utilized. Thus, in these sensors the refraction index of the glass and the fiber occupy the pivotal role. These sensors can be utilized for a variety of purposes. The most prominent of its applications are: Measurement of pressure changes in gels Measurement of pressure changes in various liquids Measurement of refractive index changes in gels Measurement of refractive index changes in different types of liquids Measurement of the level of a liquid in a vessel and this application is utilized in various industries to measure liquid levels These sensors have an accuracy of about 5 percent and are gaining importance in various industries for their usefulness. 3.6 SOFO SENSORS These are fiber optic sensors which are utilized for strain measurement. These sensors have become quite popular owing to their innate merits. Out of all the fiber optic sensors, these sensors are the ones which are being used most extensively today. These sensors are being used to measure curvature and various other parameters in giant civil structures. These sensors form a part of the interferometric system (Vurpillot et al., 1998). Also, these sensors have the ability of measuring the parameters in an absolute manner using low-coherent light. The important properties of these sensors are: These fiber optic sensors enjoy a high resolution. The resolution of these sensors is 2  µm These sensors can be of varied lengths. Their length can be as small as 0.2m or can be as large as 20m. Also, these sensors have the property of being temperature compensated The SOFO system setup consists of a number of equipments. The main components of the SOFO system setup are: It consists of a fiber optic sensor which forms the crux of this monitoring system. It is the most important component of the monitoring system. It consists of a sensor chain with partial reflectors. One terminal of this sensor is connected to the coupler Another terminal of the sensor chain with partial reflectors is connected to the LED. The coupler in turn is connected to the photo diode and a mobile mirror. This whole portable reading unit is connected to portable computer terminal. This ensures that that the whole monitoring system can be taken to the location and can be directly used at site. These sensors can be utilized in two ways. They can either be embedded in the structure at the time of the construction of the structure. Or, they can used to measure the various parameters externally. Though in both the cases, that is, in case of embedding or in the case of external anchoring, the performance of the sensors remains the same, but still, in modern smart structures, embedding is preferred (Perez 2001). This is because, in the case of embedded sensors, the sensors continuously measure the parameters and are easy to manage. Whereas in the older structures, where embedding is not preferred, external anchoring is used. Chapter 4: CASE STUDIES Case study 1: Monitoring of San Giorgio pier San Giorgio pier is a massive concrete structure. Its length is about 400metres. It

Animal Farm Essay example -- Literary Analysis, Orwell

I. Subject Animal Farm is about a group of animals that rebel against the farm owner in order to gain control of the farm and to be treated with more respect. It begins by explaining how the animals are wrongly treated by their owner, Mr. Jones. The setting is never made clear throughout the story but it is obvious to be set in the past, because of the dialog used as well as the tools used around the farm. Almost every animal in the story is a main character, although some standout more than others, including; Napoleon, Snowball, Mr. Jones, Old Major, and Boxer. Old Major is the protagonist in this novel because he is the character who instilled the correct morals into each animal. The animals are selfish and in the end, nothing turns out to be in their favor. Mr. Jones, the owner of the farm is cruel and mistreats his animals and does not take proper care of his farm. One day, the Old Major who is the wisest pig, tells the rest of the animals about a dream he has been having to get rid of their human master and run the farm on their own. After Old Major's death, two new leaders of the farm come into power and run Mr. Jones off of the farm which leaves the animals to fend for themselves and to take care of the farm by using a group effort. For a while, the animals work as hard as they possibly can to keep the farm in pristine condition and keep every animal fed with abundant amounts of food. The animals truly did keep much better care of the farm than Mr. Jones ever had. Shortly after, Napoleon becomes so selfish because of his power over the other animals on the farm, that he blocks Snowball from all of his power which then turns the other animals against him. Napoleon then uses Boxer, an intelligent horse to persuade t... ...n two legs. In the beginning of the story they were convinced to never walk on two feet because that was how their enemies walked. 9 IX. Genre The main genre of Animal Farm is political. Political is â€Å"a novel that deals with significant aspects of political life and in which those aspects are essential ingredients of the work† (Harmon 400). This novel has a political genre because it deals with politics in real life. Mainly the Soviet Revolution. A sub drama of Animal Farm is allegory. This means â€Å"a form of an extended metaphor in which objects, persons, and actions in a narrative are equated with meanings that lie outside the narrative itself. It represents one thing in the disguise of another† (Harmon 12). This novel is an allegory because every character and event that took place in the book represented something that happened in real life.

How Wilfred Owen Presents the Horror of War in Dulce et Decorum est Ess

How Wilfred Owen Presents the Horror of War in Dulce et Decorum est In the First World War people wanted the young men to go to war, but no-one really knew about conditions of the fighting in the war. Wilfred Owen was one of the people who wanted to tell the public what war was really was like. He tried to do that through his poetry. One of his poems "Dulce et decorum est" shows the horror of war very well. We know that Wilfred Owen really does know what he's talking about as he served through most of the war and died shortly before the armistice. I am going to compare "Dulce et Decorum est" with other poems on the horror of war. "Dulce et Decorum est" is short for the Latin saying "Dulce est Decorum est Pro Patria mori" this means, it is a great and wonderful thing to die for one's country. Wilfred Owen tries to tell us that this is the opposite of what war was actually like. "Bent double like beggars under sacks" is how he describes the soldiers returning from the front line. This is not the patriotic view that the public was given. Wilfred Owen shows the horror of war by telling us that the young men in war were acting like old men who had trouble walking and are tired and weary from life. This isn't the image we should have of the young men that are going to protect the country and that they are the people the paper talked about. The poem describes a gas attack and alerts our senses by telling us the effects of the gas attack on a person that fails to put their gas mask on in time. By telling us things like that it alerts our senses and we imagine that we're choking and that it could be us that are choking and that ... ...et Decorum est" experienced, they experienced the direst horrors of 1914 war, they heard the shells dropping, they saw their friends die; they had to live in the trenches. Modern day war doesn't happen like this so the only people left to witness the horrors after they are dead are the family who have lost a son or a father or a brother. The poem is set out simply. It has two stanzas and has a simple rhyming pattern. I think this gives it a very simple understated mood that you would get when a child speaks to you about their day at school. This gives over the affect that war is only sad for those who understand it. The child who is speaking doesn't really understand the concept of war. I am given this impression because the child speaks of everything else first, and then last mentions the girl whose father died.
