Is the Media Leading Non-smokers to Smoke in The United States - Assignment Example Scientific studies have proved beyond doubt that smoking causes a lot of health problems like cancer, cardiovascular diseases, high BP, lung diseases, Osteoarthritis etc. In women smoking during pregnancy can affect the growth of the fetus. Moreover, smoking can create a lot of social impacts as well as non-smokers never like the company of smokers. Media plays a vital role spreading smoking habit and hence I want to make the authorities aware of their futile efforts to prevent smoking by asking the ad people to include warning signals rather than completely prohibiting the tobacco products, through this research The influence of movie stars is so high among the public, especially among teenagers and youths. People have a tendency to mimic whatever the film stars or celebrities do. These film stars often display smoking in a particular style which encourages even non-smokers to have a try because of the influence of celebrity culture among the public. The non-smoker who adopted smoking just for mimicking the celebrity unknowingly becomes a smoker because of the addiction tobacco can contribute to the smokers. â€Å"Smoking in movies is often associated with the characteristics that adolescents find appealing, such as toughness, sexiness and rebelliousness† (Hood Center, 2006) â€Å"There is mounting evidence suggesting that adolescents whose favorite actors or actresses smoke on screen are more inclined to take up smoking themselves† (Anti-smoking ads at the cinema only work for young non-smokers, 2007) â€Å"This 1987 marketing document from the Philip Morris collection reveals an ad agency testing various themes about secondhand smoke on behalf of the Philip Morris Tobacco Company (PM). A major theme of the ads was that "the case isn't proved" that secondhand tobacco smoke harms nonsmokers, ironically the same theme that the tobacco industry used for years to reassure smokers about primary smoking and keep them smoking†.

Area of Study Journeys Essay Example for Free

Area of Study Journeys Essay In a Journey, a traveller can gain new perspectives of themselves and the world around them by taking on opportunities to learn. The novel ‘Raw’ by Scott Monk demonstrates these ideas by writing about a young boy named Brett, who hates authoritative figures such as the police. A change is perspective is shown in the late chapters when Brett is at the farm, meeting new friends and learning how lucky he is. What also changes Brett’s attitude to himself, other people that are the friends that he makes during the novel and a girl that he is willing to meet, even if he goes the prison. Brett’s punish for escaping from the Farm has change view of making decisions. Instead of judging and disliking a person, Brett has shown to change his views of other people on his journey. The Poem, ‘The road not taken’ by Robert Frost also exhibits the opportunity to gain new perspectives in the poem, through the use of an extended metaphor about the journey of life. This is shown in the poem when the persona apologises for not being able to take both sides of the road. Disappointment is shown when the persona gives a ‘sigh’. This shows how melancholic he is by giving a deep audible breath. A personal voice is used in the poem to create immediacy. In ‘Raw’, Brett’s journey to the Farm to meet new people and serve as a sentence instead of jail, has given him the opportunity to gain new perspective of himself and the world around him. Because of his journey, he decides to change how he feels about people such as his warden Sam and the police. The change made in the novel is that he chooses to call the police how they are called in instead of ‘pigs’. He has proven himself to be a selfless person when he saw his younger friend Frog, being tricked by a grown man. Immediately, he steps in to take Frog back to the Farm, even though he is up against an obstacle greater than himself. This noble act would not have happened at the beginning of the novel, because early in the chapter Brett feels that he is hated by everyone. His decision to prevent Frog from taking drugs is due to forming a close friendship with him and Brett’s guilt for allowing his friend to leave his sight. This is evident from the quote, ‘Give it back to him, Robbie’. Brett has also gain a new perspective of him after listening to Josh’s unfortunate story of his past. Josh’s story has made Brett thought of how promising his life can be because of the parents he has. He has learnt that the world has nothing against him and that he is only isolating himself from people who wish to know him. There is a lot of change in Brett, because at the beginning of the novel Brett is shown to be an extremely unpleasant person when speaking and looks at the police in a negative way. This is a contrast between Brett’s pre journey when he ran at the streets stealing a bott le store to his after journey, learning that only he can change his life. Brett’s Stream of consciousness can be seen by the readers a where he moves from his immature attitude to a wiser person when he listens to others and thinks about what he is doing. Brett and Josh have shown to have a friendlier approach to each other after Josh covered his fight with Smiling Joe. This demonstrates a change in Brett’s perspective because of Brett’s first run in with Josh, they immediately judged and dislike each other, treating one another like criminals. Whereas now they are able to understand each other. The reason for this is because of Brett appreciating Josh’s help. This is another contrast in Brett’s Journey, changing how he feels about others. We know how appreciative Brett is when he said ‘Thanks for that’ and ‘Sticking up for me’ After Brett’s escape from the Farm, not only is he punished but everyone else at the Farm is also punished for his actions. This is what makes Brett learn that there will always be consequences for his behaviour on the farm. Because of the punishment, Brett no longer tries to make an escape at Farm, after his first attempt. He also does not lie to the police when they ask him about stealing liquor from a man. This is because on his journey, meeting Caitlyn changes his decision of giving himself up and finish his sentence in jail instead of running away from the police to hide. A feeling of regret is made at the beginning of the poem for not being able to take both sides of the road. The persona in the end found that the path he took was a choice that he should not regret since not all opportunity can be taken and that it is very unlikely that he will ever comeback for the other path to discover what it is like. This is because after one road, he may encounter another and have to neglect the other. His wordchoice, ‘sorry’ conveys his feeling of regret. ‘The road not taken’ presents us the decision made in the journey of taking only one path of a diverged road because the persona may not be able to take the other path in future. The path he has taken is the one less travelled by and has changed his life. He has made an indication to us that the choice he decides is the more difficult one out of the two but the difference is that his one has been rewarding. This is said is the last two lines of the last stanza. There is a change in tense in the last lines, showing that he is happy with his decision. The past tense signifies that he want to look back at his decision later in life. A personal tone is used throughout the poem by having the persona speaking in first person. The composer allows the reader to observe what the personas knows or sees. This creates an immediate connection with the readers and persona. With this technique, we are drawn into his world, life and mind. We see what he tells us when he could not take both paths and later shows the he is satisfied with his choice. To sum up, A journey give the traveller a change in their attitude themselves other people. It is shown by composers with techniques to demonstrate the idea in the text such as the contrast of a person’s pre and after journey, when we track their inner thoughts through Stream of Consciousness. Our Wordchoice can expose how we feel in what we say and the use of first person allows us to connect with the persona.

The Yellow Wallpaper, by Charlotte Perkins Gilman -- Literary Analysis

Charlotte Perkins Gilman wrote an amazing story in 1892 entitled â€Å"The Yellow Wallpaper†. The story is full of symbolism and was inspired by Gilman's own life struggles. This analysis of her work will cover some important parts of the author’s life, the characters, the setting of the story, and the plot. Throughout the analysis will be explanations of symbols and how the author tied her personal experiences into the story. Charlotte Perkins Gilman’s work, â€Å"The Yellow Wallpaper† is a story that the author wrote to depict her own struggle with mental illness. In order to really appreciate this story, it may help to know about the author’s life. Born in 1860, she was the only child of Mary Finch Westcott and Frederick Beecher Perkins, a librarian and writer. It is said that Charlotte’s father abandoned his family, and, on the verge of poverty, they were forced to move around frequently (Merriman). At the age of 24, Charlotte married her first husband, Charles Watson Stetson, with whom she bore a daughter, Katharine Beecher Stetson. Shortly after giving birth, Charlotte began to suffer from severe postpartum depression and had a nervous breakdown. She spent some time at a sanitorium in Pennsylvania, under the care of Dr. Silas Weir Mitchell (Merriman). In 1913, Gilman wrote â€Å"Why I Wrote ‘The Yellow Wallpaper’†; For many years I suffered from a severe and continuous nervous breakdown tending to melancholia – and beyond. During about the third year of this trouble I went, in devout faith and some faint stir of hope, to a noted specialist in nervous diseases, the best known in the country. This wise man put me to bed and applied the rest cure, to which a still good physique responded so promptly that he concluded that there was no... ... the characters in the story, the setting of the story, and the plot of the story. While times have changed drastically since Gilman wrote her story, it is my hope that women everywhere will read â€Å"The Yellow Wallpaper†, recognize the struggles she faced in her life, and be grateful that she chose to not accept the advice of a male physician wanting her to submit to a domestic, docile, stereotypical housewife sort of life.

Assault and Battery

Introduction In the context of criminal law, â€Å"assault and battery† are typically components of a single offense. In tort law, â€Å"assault† and â€Å"battery† are separate, with an assault being an act which creates fear of an imminent battery, and the battery being an unlawful touching. Assault and battery are intentional torts, meaning that the defendant actually intends to put the plaintiff in fear of being battered, or intends to wrongfully touch the plaintiff.The wrongful touching need not inflict physical injury, and may be indirect (such as contact through a thrown stone, or spitting). This article describes the law of assault and battery as it is commonly applied, although the law may vary in any specific jurisdiction. Assault An assault involves: 1. An intentional, unlawful threat or â€Å"offer† to cause bodily injury to another by force; 2. Under circumstances which create in the other person a well-founded fear of imminent peril; 3. Where there exists the apparent present ability to carry out the act if not prevented.Note that an assault can be completed even if there is no actual contact with the plaintiff, and even if the defendant had no actual ability to carry out the apparent threat. For example, a defendant who points a realistic toy gun at the plaintiff may be liable for assault, even though the defendant was fifty feet away from the plaintiff and had no actual ability to inflict harm from that distance. Battery A battery is the willful or intentional touching of a person against that person’s will by another person, or by an object or substance put in motion by that other person.Please note that an offensive touching can constitute a battery even if it does not cause injury, and could not reasonably be expected to cause injury. A defendant who emphatically pokes the plaintiff in the chest with his index finger to emphasize a point may be culpable for battery (although the damages award that results ma y well be nominal). A defendant who spits on a plaintiff, even though there is little chance that the spitting will cause any injury other than to the plaintiff's dignity, has committed a battery.

The Cottage – Creative Writing

It was exactly a week after my first day at NFG, and I had brought both overnight- and sleeping bag with me to school, as had everyone else in my class – it was time for the ‘get to know each other'-trip. The ‘get to know each other'-trip is a trip were the new students can get to know each other. Every 1.g-class has to go, not alone of course. The class goes along with a pair of teachers and two older students: ‘Introes'. My class, Susanne, Steen Carl, our two introes Nadia and Jakob and I were going to Middelgrunden in Middelfart, so the time in the bus weren't long and only made shorter by song and small-talk. It took 5 minutes, after getting off of the bus, to reach our destination: The Cottage, a nice and small place mainly used by scouts. After getting settled into our dormitories, we all joined in the large dining room for tea, cake and coffee. Then, after having stuffed our stomachs with homemade cake, we had to have an hour or two dedicated to our education. In that time we took some important behavior related problems up to debate, and we did so by being divided into six groups. We had to discuss the subject, then, create a presentation or sketch, which we had to use in front of the rest of the class to get the debate started. When we finished we had a set of ground rules about our behavior in class. Then, we had to do an Orienteering's race, which our introes had put together. To keep us busy I suspect, and we were busy, busy having fun and getting to know each other through songs and dancing. As we got closer to dinnertime, something strange happened: the boys disappeared, into the kitchen, to make Spaghetti Bolognese, and it wasn't that bad. After dinner everybody seemed to need some time relaxing, and some of the boys and girls wanted to do so in water, and even though Jakob hadn't brought a bathing suit, some of the boys still figured, that he should get into the water with them; poor Jakob got absolutely soaked through and through. Then Dee figured something out, they weren't the only ones relaxing in the ocean; the jellyfish had arrived. When everybody was back at the cottage, and everybody had dried off, it was the introes turn figure something, everybody had to show them what kind of song they'd sung, dance they'd danced and any other kind of entertainment we had created during the O-race. When we were done with the performances, everybody was tired and there were only one more thing we needed to figure out for the day, a theme for the 1.g-party, we finally reached an agreement about a Christmas-theme (Elves, Santa Claus etc.) After that we were free to do as we wanted, whether we wanted sleep or games. The next day we had to get up early and eat breakfast, so that we could cram some time for educational purposes into the mix of cleaning and packing. We ended up having sort of like a civics test, which was fun. Then, all that was left was the bus ride home to the school, and getting home afterwards. As for the conclusion about the small trip with my new class, I've figured; we had fun and the trip served its purpose, as I now know a class filled with great people.

Education And Egalitarianism In America Essays - Educational Stages

Education And Egalitarianism In America Essays - Educational Stages Education And Egalitarianism In America The American educator Horace Mann once said: As an apple is not in any proper sense an apple until it is ripe, so a human being is not in any proper sense a human being until he is educated. Education is the process through which people endeavor to pass along to their children their hard-won wisdom and their aspirations for a better world. This process begins shortly after birth, as parents seek to train the infant to behave as their culture demands. They soon, for instance, teach the child how to turn babbling sounds into language and, through example and precept, they try to instill in the child the attitudes, values, skills, and knowledge that will govern their offspring's behavior throughout later life. Schooling, or formal education, consists of experiences that are deliberately planned and utilized to help young people learn what adults consider important for them to know and to help teach them how they should respond to choices. This education has been influenced by three impo rtant parts of modern American society: wisdom of the heart, egalitarianism, and practicality... the greatest of these, practicality. In the absence of written records, no one can be sure what education man first provided for his children. Most anthropologists believe, though, that the educational practices of prehistoric times were probably like those of primitive tribes in the 20th century, such as the Australian aborigines and the Aleuts. Formal instruction was probably given just before the child's initiation into adulthood the puberty rite and involved tribal customs and beliefs too complicated to be learned by direct experience. Children learned most of the skills, duties, customs, and beliefs of the tribe through an informal apprenticeship by taking part in such adult activities as hunting, fishing, farming, toolmaking, and cooking. In such simple tribal societies, school was not a special place... it was life itself. However, the educational process has changed over the decades, and it now vaguely represents what it was in ancient times, or even in early American society. While the schools that the colonists established in the 17th century in the New England, Southern, and Middle colonies differed from one another, each reflected a concept of schooling that had been left behind in Europe. Most poor children learned through apprenticeship and had no formal schooling at all. Those who did go to elementary school were taught reading, writing, arithmetic, and religion. Learning consisted of memorizing, which was stimulated by whipping. The first basic textbook, The New England Primer, was America's own contribution to education. Used from 1690 until the beginning of the 19th century, its purpose was to teach both religion and reading. The child learning the letter a, for example, also learned that In Adam's fall, We sinned all. As in Europe, then, the schools in the colonies were strongly influenced by religion. This was particularly true of the schools in the New England area, which had been settled by Puritans and other English religious dissenters. Like the Protestants of the Reformation, who established vernacular elementary schools in Germany in the 16th century, the Puritans sought to make education universal. They took the first steps toward government-supported universal education in the colonies. In 1642, Puritan Massachusetts passed a law requiring that every child be taught to read. And, in 1647, it passed the Old Deluder Satan Act, so named because its purpose was to defeat Satan's attempts to keep men, through an inability to read, from the knowledge of the Scriptures. The law required every town of 50 or more families to establish an elementary school and every town of 100 or more families to maintain a grammar school as well. Puritan or not, virtually all of the colonial schools had clear-cut moral purposes. Skills and knowledge were considered important to the degree that they served religious ends and, of course, trained the mind. We call it wisdom of the heart. These matters, by definition, are anything that the heart is convinced of... so thoroughly convinced that it over-powers the judgement of the mind. Early schools supplied the students with moral lessons, not just reading, writing and arithmetic. Obviously, the founders saw it necessary to apply these techniques, most likely feeling

Panic Disorder and other Anxiety Disorders

Panic Disorder and other Anxiety Disorders Free Online Research Papers Panic Disorder is apart of a larger class of psychological disorders known as Anxiety Disorders. Subjects with panic disorder have what are known as panic attacks which can occur at any time for any number of reasons. During panic attacks subjects will have labored breathing, heart palpitations, chest pain, intense apprehension, and fear of losing control. There are medical and psychological ways of treating this disorder. The psychotherapy way of treating Panic Disorder is known as Panic Control Treatment. Panic Control Treatment can be split up into five main sections or steps. These sections include educate and inform subject with regard to symptoms, exposing the subject to interoceptive sensations that remind them of panic attacks, cognitive-behavioral therapy, deep muscle relaxation, and assigning homework. The first step in Panic Control Treatment is to educate and inform with regard to the symptoms. You start this by diffusing the danger and reassuring the subject that his symptoms do not have fatal consequences. Start with the heart rate, subject having panic attacks experience heart rates of up to 200 beats per min. Assure the patient they are not having a heart attack and the human heart can beat that way for days. Second is suffocation. Your brain has reflex mechanisms to make you breath. If a person feels like they are going to faint it is due to rapid breathing high in their chest with leads to a decrease of oxygen in the body causing hyperventilation. The effects of any change in the level of carbon dioxide include your heart pumping harder and faster, increased constriction of blood vessels in brain (feeling of dizziness disorientation), and increased alkalinity of nerve cells, (more jittery excitable). When this occurs the subject should breathe from their diaphrag m and/or use the vasa vegal reflex which involves putting palms together in front of chest to prevent fainting. Another technique is to breathe into a paper bag to prevent hyperventilation. The weakness the body is experiencing is due to dilated blood vessels and high levels of adrenaline. Dilated blood vessels keep the blood from circulating in a functional fashion. The second step is to expose the subject to clusters of interoceptive sensations that remind them of panic attacks. They do this by having the subject perform various tasks to create the sensations. This can include spinning in a chair to invoke nausea and dizziness, hyperventilating to cause tingling, disorientation, and shortness of breath. The therapeutic effects were proved by Carter in ’95. He found that safe places make a person less likely to panic therefore the sensations do not as a matter of course lead to panic. Cognitive-Behavioral Therapy is the third step or section. Cognitive-Behavioral Therapy starts with the basic attitudes and perceptions concerning the dangerousness of the feared situation. This starts with identifying the danger. Subjects are expected to keep a diary of cognitions and interoceptive sensations. The diary is to be put into the form of situation, symptom security, and thoughts. For example a subject is sitting in his office and begins to choke, feel mildly dizzy, and increased heart rate. Consequently the person begins thinking â€Å"Oh I can’t have a heart attack here! People will see me and I might get fired. I’m suffocating and I’m going to faint.† Next we try to explore external stimuli as a trigger. The office in this situation could have been stuffy and/or warm which caused these feelings of suffocations. Another possibility is that the subject was under a lot of stress and had negative or fearful thoughts before the symptoms o ccurred. Not all stimuli are in awareness therefore some probing or exploring of possibilities is necessary. Lastly decatasrophize the situation by using a disputation. The fourth step is deep muscle relaxation including systematic desensitization and breaking retraining. This is effective for many different reasons. One of these reasons is that the response is incompatible with fear therefore replacing it with relaxation. Jocobson’s research conducted during the 30’s found that S.N.S. arousal is not possible when striated muscles are relaxed. It was reported that deep muscle relaxation had a direct correlation with blood pressure decrease and improvement of ulcer catilus. Wolpe’s ’58 was the first experiment to develop a method fro treating phobias with muscle relaxation. This allowed for gradual exposure to stimuli that the subject fears while maintaining control of symptoms. In order for this to happen the subject must be trained to relax all muscles in the body. After this the subject sets goals and clarifies vague complaints. The next step is to develop hierarchies. The subject will then act out these hierarchi es gradually exposing them to the â€Å"supposedly† harmful stimuli. Apart of this step is the Anxiety Scale which is a common way of rating your current state of anxiety. The therapeutic effect of this is to reduce anxiety increases before cognitive and S.N.S. arousal are excessive. The final step of Panic Control Treatment is to assign homework. A lot to the therapy and treatment for panic disorder will be conducted during everyday life. This homework includes relaxation training, and challenging catastrophic thoughts. Another part of the homework is to enact the actual tasks, such as using the hierarchies and coping statements. Coping statements are statement subject repeat to themselves based on actual experiences. The National Institution of Mental Health conducted a study on Panic Control Therapy at four separate University research centers. The study original study was headed by Barlow in 1989 and the follow up also by Barlow in ’91. The 304 subjects in the study had a baseline of five panic attacks per week and were randomly assigned to four conditional groups. The study was carried out over 12 weeks. The independent variable in the study was P.C.T. and drug treatment. The drugs used in the study were Tricyclic Antidepressants. Group 1 was given P.C.T. and the drugs. Group 2 was given P.C.T. and a placebo. Group 3 was given only P.C.T. Group four received only the drug. Groups 1, 2, and 4 all had the same results. 90% of the subjects in these groups were panic free at the end of the 12 weeks. Group 3 only saw 49% of subject become panic free at end of 12 weeks. Other studies like this one were done by Barlow and Clark ’94, Barlow ’97, and Clark ‘2001 with a 15 month follow up. At the two year follow up the subjects in Groups 1, 2, and 4 were all panic free while Group 3 got sick again. In conclusion the National Institution of Mental Health, Public Health Division issued a quote, â€Å"The psychological treatment should offered initially, followed by drug treatment, for those patients who do not respond adequately of for those who psychological treatmen t is not available!† Research Papers on Panic Disorder and other Anxiety DisordersPersonal Experience with Teen PregnancyThree Concepts of PsychodynamicThe Hockey GameGenetic EngineeringPETSTEL analysis of IndiaRelationship between Media Coverage and Social andThe Spring and AutumnThe Masque of the Red Death Room meaningsIncorporating Risk and Uncertainty Factor in CapitalBionic Assembly System: A New Concept of Self

5 Signs You May Be the Right Person for the Job

5 Signs You May Be the Right Person for the Job Jobs are anything but one size fits all. In fact, another candidate’s â€Å"perfect† position may be your employment nightmare. So how do you know which job promises success and fulfillment and which job harbors only frustration and failure? The short answer? You don’t. But there are some signs to look for throughout the process which can indicate that you’re indeed the right person for the job. Let’s count them down. 1. You’re Charged Up By the Thought of the JobAre you thrilled by the mere thought of the roles and responsibilities involved with a particular job or specific company? Would you wake up every morning looking forward to getting to work and making a contribution? If so, this is a strong indication that the job may be a terrific fit.If, however, you feel more excited about getting any job than about the specifics of the job at hand, this should trigger an alarm.2. You’ll Be Crushed If You Don’t Get ItNo one likes to be rejected. But if the thought of being rejected from a particular job is especially crushing, this may indicate that the job offers a unique opportunity. After all, there are hundreds of thousands of different jobs available at any given moment. If your heart is set on this one above everything else in the job classifieds section, you’re probably the right person for the job.3. It’s In Line With Your Career GoalsHave you always dreamed of working in a specific industry or of being responsible for a certain set of core job functions? If a job offers the opportunity to realize your goals and ambitions, it’s a natural leap to the conclusion that it’s not only the right job for you, but an unprecedented opportunity.Alternatively, if a job feels like a detour from your career path or a step in an uncertain direction, it merits more consideration: can it ultimately help you reach your career goals?4. You’re a Good Culture FitToday’s employers ar e increasingly prioritizing cultural fit - as opposed to mere functional fit - as an important part of the hiring process. This consideration should go both ways. If your beliefs and core values are aligned with a prospective company’s views on everything from collaboration to work/life balance to giving back to the community, this bodes well for your level of satisfaction, productivity, and staying power.5. There’s Plenty of Room for GrowthA job that’s a good fit for you at this particular moment in time may not be a good fit for you five years from now. The â€Å"right† job is not just one that makes sense in the here and now, but is also one with plenty of room for growth.The potential for advancement can also help keep you motivated, inspired and engaged on the job - critical attributes when it comes to professional fulfillment.Ultimately, it’s impossible to know with absolute certainty whether a job is the right one for you. However, these five tips can help you make the most informed and beneficial decision.

The Principal Object of Management - Essay Example Most scholars have proposed different models of organization management as well as different models of choosing the model that best fits an organization. He is fast to note the interests of both the employer and employee are the same, and one cannot prosper without the other. Both the employer and the employee should train each individual to produce at his highest possible level of efficiency In his book, â€Å"The Sociology of Organization: Classical, Critical and Contemporary Reading, Handel, Michael (2003) provides a collection of several scholarly articles on Organizational Theories. I will examine some of the models in the collection, highlighting their weaknesses and their strengths. Weber, (2009, pg 50) classifies authority basing on the allegiance pledged by the subjects to their leaders. He identifies three types of authority. In Rational Authority, the subjects submit to authority by virtue of legal issues. They don’t have any intimate relational issues with the senior. This system is common in firms which have established themselves over time such that the subjects submit to the leader by virtue of submitting to the firm. A good example is in today’s modern states, whereby the citizens are not directly loyal to the president, or the government, but the legal system of the nation. Traditional authority, in its part, features subjects who submit to traditions surrounding the authority. For instance, the subjects of a kingdom pledge their allegiance to the king’s son simply because he is of a certain bloodline. He contrasts both of these to Charismatic Authority, in which subjects devote themselves to an individual based on her expertise an d exceptional character. He argues that the most superior form of administration in any organization is bureaucracy, which in its part implies individual domination by knowledge. This attributes to the precision of decision making,  clarity and consistency of knowledge.  

Critically evaluate the nature of the relationship between Essay

Critically evaluate the nature of the relationship between intellectual property law and competition law, with particular emphasis on the European Union - Essay Example Article 101 and 102 were regulated as a means of achieving this goal.5 Eventually, the main aim of monitoring competition between undertakings is to protect consumer welfare by striving economic activities. IPRs seem to create conflict with the free movement of goods and services based on the provisions of Article 34 and 36 TFEU6. This essay will critically evaluate the relationship between IP law and Competition Law by focusing on EU perspectives. It will review Article 101 and 102 TFEU on IPRs after indicating detailed information about tension between two disciplines as well as their objectives and policies7. Indeed, since intellectual property rights entitle their owners to exclusive rights on the one hand, while competition law aims to preserve markets open on the other, an inherent tension between the two areas of law is a challenge to their implantation8. Among the main aims of the EU is to set a system of competition law. That informs the reason for creating Article 101 and 102, the Merger Regulation, and State Aid rules. It also explains the justification to pursue a central role in the Treaty as the means for maintenance of effective competition within the European Union.9Besides, The Court of Justice has routinely reaffirmed that the implementation of IPRs, in principle, must correspond to the rules of competition (Article 101 and 102), as well as the rules of free movement of goods referred in Article 34-3710. IPRs are protected under national laws of individual EU countries. Thus, the existence of different national laws on intellectual property produces some difficulties in the EU because of its integration of the single market integration.11 Regarding the aim of free movement of goods throughout the EU, Article 34 (TFEU) outlines restrictions on imports.†12 Article 36 states, â€Å"the protection of industrial and commercial property13† can justify a

Tate Modern topic proposal 200-300 words Essay Example | Topics and Well Written Essays - 500 words

Tate Modern topic proposal 200-300 words - Essay Example As it goes with the character of a building intended to house Modern Art, Herzog & de Meuron decided in favour of retaining the quintessentially urban and industrial character of the original building. However, they extended full expression to their creative genius by delicately emphasizing it through the usage of renovations like light paintwork, polished concrete, excellent lighting and unpretentious wooden floors. The result was the creation of an architectural ambience that relied for its originality on the pleasing contrast of the industrial boldness of the original building with the tasteful temperament of the new additions. It would not be wrong to say that the approach of Herzog and de Meuron in the case of Tate Modern was primarily conceptual and not design oriented. In that context, Tate Modern suggests an entire new approach towards architecture that is innovative, believing in extending new meanings and forms to the old through the incorporation of novel trends and creati vity and no doubt pragmatically aspiring for cost effectiveness.

Human Resource Management Research Paper Example | Topics and Well Written Essays - 1000 words

Human Resource Management - Research Paper Example Introduction Before going into the discussion regarding compensation and benefits, which is one of the most specialized parts of the human resource management, let us get a better understanding of the importance of a well-structured compensation plan in maintaining a productive workforce. A compensation plan is a set of those rewards, remuneration, and benefits, which are provided to the employees by the HR department of the company in order to increase employee productivity. Compensation plans not only help the companies retain skilled employees but also assist HR staff in recruitment processes. Obringer (n.d.) asserts, â€Å"To make your company competitive and attractive to job candidates, you have to offer an exceptional total benefits package†. The thesis statement for this paper is, â€Å"Why is it important for a company to offer a well-structured compensation plan to its employees?† Importance of Compensation Plans Compensation and benefits play an important rol e in making a company achieve increased employee productivity. A well-structured compensation plan is one of the key motivating forces behind increased productivity. If human resource department of a company offers a competitive compensation plan to the employees as a reward for their individual performances, the employees become motivated and they put their efforts to do more for their company. Employee efficiency and organizational productivity depend directly on the types of compensation that are offered to the employees by the company. It is a common fact that the employees like to work for such companies, which give value to the employees’ needs and demands by offering them attractive compensation plans. Keimig (2008) asserts, â€Å"Generous benefit packages (especially those with an emphasis on health insurance and retirement savings) tend to attract employees who are looking for long-term, stable positions†. A well-structured compensation plan needs various fact ors to be considered during development, which include type of the compensation plan, conditions for plan implementation, payment calculation method, culture of the organization, and practicalities of the compensation plan. Some of the main reasons behind the need to design and implement a well-structured compensation plan include increasing employees’ moral, ensuring internal and external equity, reducing the turnover, encouraging employees’ performance and productivity, increasing employees’ loyalty, hiring and retaining skilled staff, and making the employees satisfied with their jobs. Dalton (n.d.) states, â€Å"The employee's family can also receive benefits, should the employee die as a result of the injuries or illness sustained at the company†. Another reason for implementing an appropriate compensation plan is to succeed in today’s competitive markets. It is the 21st century and the level of competition between the companies has reached it s heights. Implementation of compensation plans play a valuable role in making the companies excels in the markets. Therefore, it is extremely important for the companies to hire and retain skilled employees in order to get competitive edge over the competitors. Why Is It Necessary To Have A Compensation Plan? It is very necessary for a company to implement a compensation plan because it increases productivity of the workforce. We can hardly find any employee who is not interested in getting higher pays and

The use of Isotopes in medicine Essay Example | Topics and Well Written Essays - 1000 words

The use of Isotopes in medicine - Essay Example Thus, isotopes are important in the diagnosis of medical conditions, treatment of certain diseases, and sterilization of equipment and products. The diagnosis of the medical conditions utilizes radioisotopes. Technetium-99 is the commonly used radioisotope, and the radiation from the element offers essential information regarding the functioning of specific organs in order to detect any malfunction. The information from the radiation enables the physicians to make accurate and quick diagnosis of the patients’ illness. Technetium-99 is the most abundant isotope of the radioactive technetium, and can penetrate into the body to provide vital information. Fundamentally, technetium-99 has important characteristics that make it useful in the diagnosis of the medical conditions. Notably, the isotope is metastable. This implies that technetium-99 has excited nucleus that emits the gamma rays to attain stability (Roat-Malone, 2003). Consequently, the emitted gamma rays are significant in medicine because they enable the medical practitioners to image the internal body parts for crucial diagnostic information. It is noteworthy that the gamma radiations are not harmful to the body. The emitted gamma rays contain ideal energy (140.5 KeV) for the detection with the gamma camera (World Nuclear Association, 2015). Similarly, the half-life of six hours makes the technetium-99 a useful element in the diagnosis of disease. In effect, the decay time is enough for the physicians to conduct any medical test. The use of the technetium-99 in the diagnosis of medical conditions has notable advantages, as well as, disadvantages. The property of technetium-99 as a pure gamma emitter is important in the analysis of the internal body parts. Gamma radiation produced by the isotope has energy levels that do not harm the human body (Roat-Malone, 2003). Hence, the radiations are safe and do not interfere with the normal

Color blue Essay Example for Free

Color blue Essay Blue is the favorite color of all people. It’s nature’s color for water and sky, but is rarely found in fruits and vegetables. Today, blue is embraced as the color of heaven and authority, denim jeans and corporate logos. It is cold, wet, and slow as compared to red’s warmth, fire, and intensity. Blue has more complex and contradictory meanings than any other color. These can be easily explained by pinpointing by the specific shade of blue. Bright blue: cleanliness, strength, dependability, coolness (The origin of these meanings arise from the qualities of the ocean and inland waters, most of which are more tangible. ) Light (sky) blue: peace, serenity, ethereal, spiritual, infinity (The origin of these meanings is the intangible aspects of the sky. ) Most blues convey a sense of trust, loyalty, cleanliness, and understanding. On the other hand, blue evolved as symbol of depression in American culture. â€Å"Singing the blues† and feeling blue† are good examples of the complexity of color symbolism and how it has been evolved in different cultures. Blue ranks so high as a favorite color that you can’t go wrong if you use blue. However, blue can be over-used and may wind up a design cliche if used alone. Combining blue with another color creates a more creative effect. Blue is the only color which maintains its own character in all its tones it will always stay blue;† Raoul Dufy, French Fauvist Painter, 1877-1953 Blue is sharply refracted by the eyes. This causes the lens to flatten and to push the blue image back. We perceive that blue areas are receding and smaller. The same refraction causes visual fog if used excessively in interior spaces. Blues global similarities are significant: Blue is the #1 favorite color of all people. 53% of the flags in the world contain blue. Blue is the most commonly used color in corporate identity. A dark blue suit is professional business attire. Blue jeans are worn all over the world. Aristocracy is blue-blooded in all European languages. Unique Meanings of Blue in Different Cultures Greeks believe that blue wards off the evil eye. The English â€Å"to feel blue† has no equivalent in other languages while in German â€Å"blau sein† (literally: to be blue) means to be drunk or in Russian â€Å"Ð ³Ã ¾Ã »Ã'Æ'Ð ±Ã ¾Ã ¹Ã¢â‚¬  (literally: light blue) means to be homosexual. Dark blue is the color of mourning in Korea. The god Krishna has blue skin. Shades of blue are described as shallow or deep instead of light or dark in China. Blue is for a baby girl; pink for a baby boy in Belgium. â€Å"Prince Charming† is called â€Å"The Blue Prince† in Italy and Spain.

Risk Factors of Sleep Disorder After Stroke:

Risk Factors of Sleep Disorder After Stroke: Risk factors of sleep disorder after stroke: A Meta analysis Running title: Risk factors of sleep disorder after stroke Highlights: Diabetes mellitus has a 41% increased risk of sleep disorder in stroke patients Alcohol use has a 59% increased risk of sleep disorder in stroke patients Habitual snoring has a 1377% increased risk of sleep disorder in stroke patients Body-mass index has a 17% decreased risk of sleep disorder in stroke patients Abstract Objectives: To explore the related risk factors of sleep disorder in stroke patients by conducting a meta-analysis Methods: PubMed, Medline, Springer, Elsevier Science Direct, Cochrane Library and Google scholar database were searched from inception up to May 2014. Studies investigating risk factors for sleep disorder after stroke were included. Characteristics including author’s name, year of publication, country, sample size, age of participants and gender were extracted independently by two reviewers. Results: A total of 8 studies, involving 1381 patients (578 experimental groups and 803 control groups) were eligible for the meta-analysis. The meta-analysis showed that there were significant association between risk of sleep disorder after stoke between diabetes mellitus (OR = 1.41, 95% CI = 1.09 to 1.84, P OR = 1.59, 95% CI = 1.19 to 2.12, P OR = 14.77, 95% CI = 5.52 to 39.53, P WMD = 0.83, 95% CI = 0.63 to 1.03, P OR = 1.23, 95% CI = 0.72 to 2.1, P > 0.05), hypertension (OR = 1.22, 95% CI = 0.83 to 1.80, P > 0.05), dyslipidemia (OR = 0.96, 95% CI = 0.70 to 1.33, P > 0.05), smoking (OR = 1.27, 95% CI = 0.73 to 2.20, P > 0.05), previous stroke (OR = 1.05, 95% CI = 0.74 to 1.49, P > 0.05), chronic obstructive pulmonary disease (OR = 0.79, 95% CI = 0.40 to 1.57, P > 0.05) when compared with control groups. Furthermore, the results of Egger test showed no statistical publication bias. Conclusions: Diabetes mellitus, alcohol use, habitual snoring and body-mass index are associated with risk of sleep disorder in patients with stroke. Key words: Sleep disorder; Risk factors; Meta-analysis; Stroke Introduction Stroke is a serious global health problem, and considered as the fourth leading cause of death and the primary cause of adult disability in all around the world [1-3]. Sleep-related breathing disorders (SDB) is a frequent clinical phenomena, and characterized by repetitive apneas and hypopneas during sleep [4, 5]. The relationship of SDB with stroke has been investigated in the recent years. Many researches have reported increased incidence of SDB in stroke patients, which could lead to progression of the stroke [6, 7]. Furthermore, SDB following stroke may result in high mortality and morbidity [4]. Although SDB and stroke have common established risk factors including age, gender, elevated body-mass index (BMI), hypercholesterolemia, hypertension and habitual snoring [8-10], risk factors leading to SDB in stroke patients remains unclear. Thus, it is important to identify contributing risk factors or associated conditions that can impact on outcome of SDB following stroke. Previously existing literature and primary analyses on risk factors of sleep disorder after stroke only involved in research of certain factor, and statistical power was deficient and insufficient in these studies [4, 11]. In this study, to investigate the risk factors for SDB after stroke and obtain a quantitative estimate of the risk, we systematically review the literature that have studied patients with stroke for SDB risk factors, (namely gender, Hypertension, Diabetes mellitus, Dyslipidemia, Smoking, alcohol use, Previous stroke history, Chronic obstructive pulmonary disease, Habitual snoring and Body-mass index)by conducting a meta-analysis. Methods Search strategy and study selection We retrieved the relevant studies up to May 2014 in several public databases, mainly including PubMed, Medline, Springer, Elsevier Science Direct, Cochrane Library and Google scholar. The main search words were â€Å"factor† or â€Å"influence†, â€Å"affect† or â€Å"element† or â€Å"determinant† or â€Å"cause† or â€Å"reason† and â€Å"sleep disorder†, â€Å"apnoea† or â€Å"obstacle† or â€Å"impediment† or â€Å"barrier† or â€Å"obstruction† or â€Å"balk† and â€Å"stroke† or â€Å"cerebral apoplexy† or â€Å"acute cerebral accident† and â€Å"research† or â€Å"survey† or â€Å"study† or â€Å"trial†. Meanwhile, references from retrieved papers were checked for more relevant studies not identified in database search. Eligibility of relevant studies For relevant abstracts, full publications were retrieved for evaluation on the basis of criteria that were established a priori. All selected research articles were considered except case reports. We sought to include studies of any design that reported risk factors in sleep disorders, and relationships between sleep-disordered breathing, sleep apnea or insomnia symptoms and stroke without the limitation of sample size and range of age. Studies were excluded from the systematic reviews and reports that only described sleep disorder after stroke. Studies with no control group were also excluded. Reviews, reduplicated studies and studies published in language other than English were excluded as well. Data extraction Information from each study was extracted independently by two reviewers using a data extraction form. Study general characteristics (e.g., author, year of publication, location of participants, design of studies, ethnicity and number of cases), and characteristics of participants (e.g., age, gender and sample size) were recorded (where available) and doubled-checked. Meanwhile, the effect size of risk factors of sleep disorder in stroke patients compared with stroke patients without sleep disorder with corresponding 95% confidence interval (CI) were extracted as reported by authors. The effect size of gender, hypertension, diabetes mellitus, dyslipidemia, smoking, alcohol use, previous stroke, chronic obstructive pulmonary disease (COPD) and habitual snoring were measured by, and body-mass index (BMI) by weighted mean difference (WMD). In addition, we contacted authors of incorporated studies to obtain further information for data items that needed clarification. Discrepancies were resolved by discussing within our research team or contracting with the original investigators via e-mail. Statistical analysis The meta-analysis was focused on the risk factors of sleep disorder in stroke patients versus stroke patients without sleep disorder. The pooled estimates of effect size of risk factors were calculated by averaging OR or WMD based on a fixed or random effects model depending on the overall heterogeneity. Then, heterogeneity of effect size across studies was evaluated by applying Cochran’s Q-statistic and and the I2 statistic [12, 13]. P value I2 value > 50% was considered to heterogenous across the studies. When substantial heterogeneity was detected, we calculated the overall estimate of ORs or WMDs using Mantel–Haenszel method in the fixed effect model [14]. If not, the pooled estimates were presented based on the random effect model by using DerSimonian and Laid method [15]. In addition, the publication bias were evaluated using Egger’s linear regression test [16], which measures funnel plot asymmetry by the natural logarithm scale of the effect size. Meta-analysis was performed using the software of the STATA package v.11.0 (Stata Corporation, College Station, TX, USA). P value Results Literature research and study characteristics The details of the literature search were shown in a flow diagram (Figure 1). We obtained 972 citations (131 from Medline, 341 from Pubmed, 164 from Springer, 103 from Elsevier Science Direct, 16 from Cochrane Library and 217 from Google Scholar) with our electronic literature search. We obtain 84 citations after removing duplicates or irrelevant studies. In addition, 47 citations were excluded after screening based on the abstracts. Then 37 remained citations were full-text reviewed for detailed assessment. Finally, 8 citations satisfied the inclusion criteria and were eligible for the meta-analysis. The characteristics and information of the included studies were presented in Table 1. The 8 selected studies contained 1381 patients with average age (ranging from 43.0 to 75.2 years old), including 578 experimental groups (stroke patients with sleep disorder) and 803 control groups(stroke patients without sleep disorder) [17-24].

Overall effects of habitual snoring As shown in Table 2, a total of 2 studies [20, 21], involving 422 stroke patients (138 experimental groups and 284 control groups), were eligible for the meta-analysis. Meta-analysis showed habitual snoring had a 1377% increased risk of sleep disorder in stroke patients compared with control groups (OR = 0.79, 95% CI = 0.40 to 1.57, P > 0.05), yet with no significant between-study heterogeneity was found (Q2 = 1.29, I2 = 22.6%, P > 0.1). Overall effects of Body-mass index (BMI) As shown in Table 2, a total of 3 studies [20, 21, 23], involving 494 stroke patients (176 experimental groups and 318 control groups), were eligible for the meta-analysis. Meta-analysis showed BMI had a 17% decreased risk of sleep disorder in stroke patients compared with control groups (WMD = 0.83, 95% CI = 0.63 to 1.03, P Q2 = 0.95, I2 = 0%, P > 0.1). In addition, the result of Egger’s test showed no evidence of publication bias (P = 0.998). Discussion In this study, we conducted a meta-analysis for investigating risk factors of sleep disorder in stroke patients. Based on the data from 8 studies including 1381 patients, the factors (Diabetes mellitus, alcohol use, habitual snoring and BMI) were associated with risk of sleep disorder in stroke patients when compared with control groups, yet with no significant between-study heterogeneity. The magnitude of this association was greatest for habitual snoring with stroke patients experiencing a 1377% increase in risk of sleep disorder compared with stroke patients without sleep disorder. However, there were no association between risk of sleep disorder after stroke and other factors (gender, Hypertension, Dyslipidemia, Smoking, Previous stroke history and COPD). In addition, there was no indication of publication bias from the result of Egger’s test. Researchers have shown increased incidence of SDB in stroke patients, which may lead to a poor outcome and recurrence [25, 26]. SDB progresses from habitual snoring to the increased upper airway resistance syndrome to sleep apnea [27], and it is biologically plausible that habitual snoring could increase the risk of sleep disorder in stroke patients. Habitual snoring is significantly associated with daytime sleepiness, restless sleep, and hyperactivity, which could lead to sleep disorder [28, 29]. In our literature search we did not identify results of any randomized clinical trials evaluating the effect of risk factors on sleep disorder after stroke. However, it is reasonable to infer that habitual snoring may contribute to incidence and development of sleep disorder in stroke patients. The previous studies have shown significant gender-related differences in presenting symptoms of patients with SDB [30], and the risk for the development of sleep disorder was significantly lower in women [31]. However, in our study, we found no association between gender and risk of sleep disorder after stroke, yet with the most significant between-study heterogeneities. This might result from unavoidable difference in study sample sizes and distinct adjustments across studies. Thus, we suggest that the present analyses might have underestimated the true effects of gender on risk of sleep disorder after stroke, and further studies are needed to be demonstrated this. The present meta-analysis has a series of limitations, such as lack of uniformity (e.g. sleep disorder diagnostic criteria, the duration of patients with stroke) and exclusion of studies written in languages other than English. Furthermore, another limitation was the narrow coverage of information of the present analysis. After all, the results in this analysis were only obtained data from Asia, Europe, North America and Oceania, and the majority of the included studies did not state if there were any racial differences among participants. The differences in regions and races among studies might have an influence on pooled risk estimates of sleep disorder after stroke. In summary, the present meta-analysis suggest that the factors (Diabetes mellitus, alcohol use, habitual snoring and BMI) is associated with risk of metabolic syndrome. The conclusion has a great significance for public health, especially in countries of high incidence of stroke. In addition, further investigations, both epidemiological and mechanistic, are needed to investigate whether regulating these factors can prevent occurrence and development of metabolic syndrome. 3D Technology: Types and Uses 3D Technology: Types and Uses CHAPTER 1: INTRODUCTION This report will focus on how different 3D technologies work, it will include the entire work flow, from recording the action, encoding the footage, playing back the media via a cinema projector or television and finally how the audience views the 3D film or video, whether it be through specially designed glasses or an auto-stereoscopic television. At present the most popular way to view 3D media is with the use of specialised glasses, the most popular being, active shutter glasses, passive polarised glasses and colour separationbased glasses. Wearing glasses to watch a movie is often mentioned as a negative aspect of 3D. There is a technology available that allows you to watch 3D on screens without wearing any additional glasses, it is called autostereoscopy, this will also be looked at. The health impacts that result from watching 3D will also be examined, along with factors that will prevent a person from being able to correctly view 3D images. There will be impacts on the entire industry from studios and cinemas to smaller production companies and independent producers if 3D films become the norm and these will be examined. A good place to start this report is to examine how two of the highest profile media companies around at present are currently viewing 3D technology. Phil McNally stereoscopic supervisor at Disney-3D and Dreamworks was quoted as saying, consider that all technical progress in the cinema industry brought us closer to the ultimate entertainment experience: the dream. We dream in colour, with sound, in an incoherent world with no time reference. The cinema offers us a chance to dream awake for an hour. And because we dream in 3D, we ultimately want the cinema to be a 3D experience not a flat one.'(Mendiburu, 2009) In the BBC Research White Paper: The Challenges of Three-Dimensional Television, 3D technology is referred to as a continuing long-term evolution of television standards towards a means of recording, transmitting and displaying images that are indistinguishable from reality'(Armstrong, Salmon, Jolly, 2009) It is clear from both of these high profile sources that the industry is taking the evolution of 3D very seriously, as a result this is a topic that is not only very interesting but will be at the cutting edge of technological advances for the next couple of years. This report will be covering the following things: What does the term 3D mean with reference to film and video A look at the history of 3D in film How does 3D technology work The implications of 3D on the film business and on cinemas The methods used to create the media and also the ways in which the 3D image is recreated for the viewer The reasons I have chosen to do my project on this topic is that I am very interested in the new media field. 3D video when accompanied with high definition film and video is a field that is growing rapidly. Earlier this year, on 02 April 2009, Sky broadcast the UKs first live event in the 3D TV format, it featured a live music concert by the pop group Keane, it was sent via the companys satellite network using polarisation technology. Traditionally we view films and television in two dimensions, this in essence means we view the media as a flat image. In real life we view everything in three dimensions, this is because we get a slightly different image received in each eye, the brain then combines these and we can work out depth of vision and create a 3D image. (this will be explained further in Chapter 3) There is a high level of industrial relevance with this topic, as 3D technology coupled with high definition digital signal is at the cutting edge of mainstream digital media consumption. Further evidence of this is that the sports company ESPN will be launching their new TV channel, ESPN-3D in North America in time for this years Summer Football World Cup. In January 2009 the BBC produced a Research White Paper entitled The Challenges of Three-Dimensional Television on this subject and over the next couple of years they predict that it will start to be introduced in the same way that HD (High Definition) digital television signal is currently being phased in, with pay-per-view movies and sports being the first take advantage of it. Sky have announced that their existing Sky+HD boxes will be able to broadcast the 3D signals so customers will not even need to update their equipment to be able to receive the 3D Channel that they are starting to broadcast later this year. On Sunday January 31st 2010, Sky broadcast a live Premier League football match between Arsenal and Manchester United for the first time in 3D to selected pubs across the country, Sky equipped the selected pubs with LGs new 47-inch LD920 3D TVs. These televisions use the passive glasses, similar to the ones uses in cinemas as opposed to the more expensive Active glasses which are also an option. (The differences between Active and Passive technologies will be explained in Chapter 8) It is also worth noting that at the 2010 Golden Globe awards, on acceptance of his award for Best Picture for the 3D Box Office Hit Avatar, the Canadian director James Cameron pronounced 3D as the future. At the time of writing this report (27/01/2010) the 3D film Avatar has just taken over from Titanic (also a James Cameron film) to become the highest grossing movie of all time, with worldwide takings of $1.859 billion. This is being accredited to the films outstanding takings in the 3D version of its release, in America 80% of the films box office revenue has been received from the 3D version of its release. In an industry where money talks, these figures will surely lead to an dramatic increase in production of 3D films and as a result Avatar could potentially be one of the most influential films of all time. After completing this dissertation I hope to be able to have a wide knowledge base on the subject and hopefully this will appeal to companies that I approach about employment once I have graduated. In the summer of 2010 when I will be looking for jobs, I believe that a lot of production companies will have some knowledge of 3D technology and be aware of how in the near future it may be something that they will have to consider adopting in the way that many production companies are already or soon will be adopting HD into their workflow. In order to ensure that I complete this project to a high standard it is important that I gain a complete understanding of the topic and study a variety of different sources when compiling my research. 3D media itself is not a new concept so there are a wide range of books and articles on the theory of 3D and stereoscopy along with anaglyphs. However in recent years there has been a resurgence in 3D with relation to film and TV. This is due mainly to digital video and film production making it easier and cheaper to create and manage the two channels needed for three-dimensional video production. It has proved more difficult to study books and papers on this most recent resurgence of 3D because it is still happening and evolving all the time. I have read various research white papers on the subject, which have been cited in the Bibliography, I have also used websites and blogs along with some recently published books, one of the problems with such a fast moving technological field such as 3D though, is that these books quickly become outdated. CHAPTER 2: HUMAN VISION In the real world we see in three dimensions as opposed to the two dimensions that we have become accustomed to when watching TV or at the cinema. Human vision appears in three dimensions because it is normal for people to have two eyes that both focus on the object, in the brain these two images are then fused into one, from this we can work out depth of vision, this process is called stereopsis. All of these calculations happen in the brain without the person ever even noticing, as a result we see the world in three dimensions very naturally. The reason that we see in 3D is because of stereoscopic depth perception. There are various complex calculations going on in our brains, this coupled with real experience allows our brain to work out the depth of vision. If it wasnt for this it would be impossible to tell if something was very small or just very far away. As humans, we have learnt to judge depth even with only one view point. This is why, if a person has one eye they can still manage to do most things that a person with two eyes can do. This is also why when watching a 2-D film you can still get a good judge of depth. The term for depth cues based on only one viewpoint is monoscopic depth cues. One of the most important of these is our own experience, it relates to perspective and relative size of objects. In simple terms, we have become accustomed to object being certain sizes. An example of this is that we expect buildings to be very big, humans are smaller and insects are smaller still. So this means that if we can see all three of these objects next to each other and they appear to be the same size then the insect must be much closer than the person, and both the insect and the person must be much closer that the building (see figure 1). The perspective depth cue (shown in figure1) was backed up when an experiment was carried out by Ittelson in 1951. He got volunteers to look through a peep hole at some playing cards, the only thing they could see were the cards and so there were no other types of depth cue available. There were actually three different-sized playing cards (normal size, half-size, and double size), and they were presented one at a time at a distance of 2.3metres away. The half-sized playing card was judged to be 4.6 metres away from the observer, whereas the double-sized card was thought to be 1.3 metres away. Thus, familiar size had a large effect on distance judgement'(Eysenck, 2002). Another monoscopic depth cue that is very effective is referred to as occlusion or interposition. This is where an object overlaps another object. If a person is standing behind a tree then you will be able to see all of the tree but only part of the person. This tells us that the tree is nearer to us that the person. One of the most important single view depth cues in called motion parallax, it works on the basis that if a person moves their head, and therefore eyes, then objects nearer to them, whilst not physically moving, will appear to move more than the objects in the distance. This is the method that astronomers use to measure distances of stars and planets. It is in extremely important method of judging depth and is used extensively in 3D filmmaking. In filmmaking, lighting is often talked about as being one of the key elements to giving the picture depth, and this is because it is a monoscopic depth cue. In real life the main light source for millennia has been the sun. Humans have worked out how to judge depth based on the shadows that are portrayed from an object. In 2D films shadows are often used to display depth by casting them across actors faces it allows the viewers to see the recesses and expressions trying to be portrayed. So far all of the methods that have been described for determining depth have been monoscopic, these work independently within each eye. If these were the only methods for determining depth there would be no need for 3D films as it would not add anything because all of these methods could be recreated using a single camera lens. This is not the case however, a lot of the more advanced methods used in human vision for judging depth need the use of both eyes, these are called stereoscopic depth cues. A great deal of stereoscopic depth cues are based around the feedback that your brain gets when the muscles in the eye are manipulated to concentrate your vision on a particular point. One of the main stereoscopic depth cues is called convergence, this referrers to the way that the eyes rotate in order to focus on an object (see figure 2). If the focus is on a near object, the eyes rotate around the Y axis and converge on a tighter angle , similarly if the focus is on a distant object the rotation means the eyes have a wider angle of convergence. It is a lot less stressful on the muscles in the eye to have a wide angle of convergence and look at objects far away, in comparison looking at very close object for any amount of time causes the muscles in the eye to ache. This is a very important factor that should be considered when creating 3D films, as it doesnt matter how good the film is, if it is going to hurt the audience it will not go down well. A second stereoscopic depth cue that we use is called accommodation, this is the way that our eyes changes focus when we look at an object at different distances, it is very closely linked with convergence. Usually when we look at an object very close up, our eyes will change rotation and point towards the object (convergence) allowing us to look at the item, our eyes will at the same time change focus (accommodation). Using the ciliarybody muscles in the eye, the lens will change shape to let more or less light in the same way a camera does, thus changing focus. In everyday life convergence and accommodation usually happen in parallel. The fact that we can, if we wish choose to converge our eyes without changing the focus means that 3D films are possible. When you are sat in the cinema all of the action is projected onto the screen in front of you, so this is where your eyes need to focus. With 2D films the screen is also where your eyes need to converge, but with 3D films this is not the case. When watching a 3D film the focus never changes from the screen, else the whole picture would go out of focus, but objects appear to be in front and behind the screen, so your eyes need to change their convergence to look at these objects without altering their focus from the screen. It has been suggested that this independence of accommodation and convergence is the reason for eye strain when watching a 3D picture as your eyes are doing something that they are not in the habit of doing (see chapter 12: Is 3D bad for you). It is also worth noting that our monoscopic depth cues work at almost any range, this is not the case with stereoscopic depth cues. As objects become further away they no longer appear differently in each eye, so there is no way the brain can calculate a difference and work out depth. The limit occurs in the 100 to 200-yard range, as our discernment asymptomatically tends to zero. In a theatre, we will hit the same limitation, and this will define the depth resolution and the depth range of the screen.(Mendiburu, 2009) This means that when producing a 3D film you have to be aware that the range of 3D that you have to use is not infinite and is limited to 100-200 yards. CHAPTER 3: Early Stereoscopic History (1838 1920) Three dimensional films are not a new phenomenon, Charles Wheatstone discovered, in 1838, that the mechanism responsible for human depth perception is the distance separating the retinas of our eyes . (Autodesk, 2008) In a 12,000 word research paper that Wheatstone presented to the Royal Society of Great Britain he described the stereoscope and claimed as a new fact in his theory if vision the observation that two different pictures are projected on the retinas of the eyes when a single object is seen.(Zone, 2007) Included in the paper were a range of line drawings presented as stereoscopic pairs, these were designed to be viewed in 3D using Wheatstones invention, the stereoscope. Wheatstone was not the first person to look at the possibility of receiving separate views in each eye, In the third century B.C, Euclid in his treatise on Optics observed that the left and right eyes see slightly different views of a sphere'(Zone, 2007). However, Wheatstone was the first person to create a device to be able to re-create 3D images. Between 1835 and 1839 photography was starting to be developed thanks to work from William Fox Talbot, Nicephore Niepce and Louise Daguerre. Once Wheatstone became aware of the photographic pictures that were available he requested some stereoscopic photographs to be made for him. Wheatstone observed that it has been found advantageous to employ, simultaneously, two cameras fixed at the proper angular positions'(Zone, 2007). This was the start of stereoscopic photography. Between 1850 and 1860 work was starting to be done by various people to try and combine stereoscopic photography with machines that would display a series of images very quickly and therefore using persistence of vision to create a moving 3D image. These were the first glimpses of 3D motion. In 1891 a French scientist, Louis Ducos du Hauron patented the anaglyph, a method for separating an image into two separate colour channels and then by wearing glassing with the same colours but on opposite eyes thereby cancelling out the image, thus reproducing one image, but in 3D. Another method used at this time to create 3D was proposed by John Anderton, also in 1891. Andertons system was to use polarisation techniques to split the image into two separate light paths and then employ a similar polarisation technique to divert a separate image to each eye on viewing. One of the main advantages of polarisation over anaglyphs is that they do not lose any colour information, this is due to the fact that both images retain the original colour spectrums. They do however loose luminance. It is common for a silver screen to be necessary, it serves two purposes, firstly the specially designed screen maintains the separate polarisation required for each image. It also reflects more light than conventional screens, this compensates for the loss of luminance. During 1896 and 1897 2D motion pictures started to take off, and by 1910 after a lot of initial experimenting the creative formats of film that we recognise today such as cuts and framing had started to become evident. In 1920 Jenkins, an inventor that worked hard to try and create a method for recreating stereoscopic motion picture was quoted as saying Stereoscopic motion pictures have been the subject of considerable thought and have been attained in several waysbut never yet have they been accomplished in a practical way. By practical, I mean, for example without some device to wear over the eyes of the observer.'(Zone, 2007) It is worth noting that this problem of finding a practical method of viewing 3D has still to a large extent not been solved. Chapter 4: Early 3D Feature Films (1922 1950) 4.1 The first 3D feature film The first 3D feature film, The Power of Love was released in 1922, it was exhibited at the Ambassador Hotel Theatre in Los Angeles. Popular Mechanics magazine described how the characters in the film did not appear flat on the screen, but seemed to be moving about in locations which had depth exactly like the real spots where the pictures were taken(Zone, 2007). The Power of Love was exhibited using red/green glasses using a dual strip anaglyph method of 3D projection. (Anaglyphs are explained in chapter 8.3) The film was shot on a custom made camera invented by Harry K.Fairall, he was also the director on the film. The camera incorporated two films in one camera body.(Symmes, 2006) Power of Love was the first film to be viewed using anaglyph glasses, also the first to use dual-strip projection. Also in 1922, William Van Doren Kelley designed his own camera rig, based on the Prizma colour system which he had invented in 1913. The Prizma 3D colour method worked by capturing two different colour channels by placing filters over the lenses. This way he made his own version of the red/blue anaglyphic print. Kelleys Movies of the Future was shown at Rivoli Theatre in New York City. 4.2 The first active-shutter 3D film A year later in 1923 the first alternate-frame 3D projection system was unveiled. It used a technology called Teleview. Which blocked the left and right eyes periodically in sync with the projector, thereby allowing you to see too separate images. Teleview was not an original idea, but up to this point no one had been able to get the theory to actually work in a practical way that would allow for films to be viewed in a cinema. This is where Laurens Hammond comes in. Hammons designed a system where two standard projectors would be hooked up to their own AC generators, running at 60Hz this meant that adjusting the AC frequency would increase or decrease the speed of the projectors. The left film was in the left projector and right film in the right. The projectors were in frame sync, but the shutters were out of phase sync.'(Symmes, 2006) This meant that the left image was shown, then the right image. The viewing device was attached to the seats in the theatre. It was mounted on a flexible neck, similar to some adjustable gooseneck desk lamps. You twisted it around and centred it in front of your face, kind of like a mask floating just in front of your face. (Symmes, 2006) The viewing device consisted of a circular mask with a view piece for each eye plus a small motor that moved a shutter across in front of either the left or right eye piece depending on the cycle of current running through it. All of the viewing devices were powered by the same AC generator as the projectors meaning that they were all exactly in sync. One of the major problems Hammond had to overcome was the fact that at the time film was displayed at 16 frames per second. With this method of viewing you are effectively halving the frame rate. 8 frames per second resulted in a very noticeable flicker. To overcome this Hammond cut each frame up in to three flashes so the new sequence was: 1L-1R-1L-1R-1L-1-R 2L-2R-2L-2R-2L-2R and so on. Three alternate flashes per eye on the screen. (Symmes, 2006) This method of separating and duplicating certain frames effectively resulted in increasing the overall frame rate thereby eradicating the flicker. There was only one film produced using this method, it was called M.A.R.S and displayed at the Selwyn Theatre in New York City in December 1922. The reason the technology didnt catch on was not due to the image, as the actual theory for producing the image has changed very little from the Teleview method to the current active-shutter methods which will be explained later. As with a lot of 3D methods the reason this one did not become mainstream was due the viewing apparatus that was needed. Although existing projectors could be modified by linking them up to separate AC generator, meaning no extra equipment was needed, the headsets that were required did need a lot of investment and time to install. All of the seats in the theatre needed to be fitted with headsets, these were adjusted in front of the audience members. These also had to be linked up to the AC generator so as they were perfectly in sync, this meant that they had to be wired in to the seats. These problems have since been overcome with wireless technologies such as Bluetooth as will be explained later. 4.3 The first polarised 3D film The next and arguably one of the most important advancements in 3D technology came in 1929 when Edwin H. Land worked out a way of using polarised lenses (Polaroid) together with images to create stereo vision. (Find more on polarisation in chapter 8.6) Lands polarizing material was first used for projection of still stereoscopic images at the behest of Clarence Kennedy, an art history instructor at Smith College who wanted to project photo images of sculptures in stereo to his students. (Zone, 2007) In 1936 Beggars Wedding was released in Italy, it was the first stereoscopic feature to include sound, it was exhibited using Polaroid filters. This was filmed using polarised technology. The first American film to use polarising filters was shot in 1939 and entitled In Tune With Tomorrow, it was a 15 minute short film which shows through stop motion, a car being built piece-by-piece in 3D with the added enhancement of music and sound effects. (Internet Movie Database, 2005) Between 1939 and 1952 3D films continued to me made but with the Great Depression and the onset of the Second World War, the cinema industry was restricted with its output because of finances and as 3D films were more expensive to make their output started to be reduced. Chapter 5: Golden Age of 3D (1952 1955) With cinema ticket sales plummeting from 90 million in 1948 to 40 million in 1951 (Sung, 2009) largely being put down to the television becoming coming in peoples front rooms the cinema industry needed to find a way to encourage the viewers back the big screen, 3D was seen as a way to offer something extra to make viewers return. In 1952 the first colour 3D film was released called Bwana Devil,it was the first of many stereoscopic films to follow in the next few years. The process of combining 3D and colour attracted a new audience to 3D films. Between 1950 and 1955 there were far more 3D films produced that at any other time before or since, apart from possibly in the next couple of years from 2009 onwards, as the cinema industry tries to fight back again against falling figures, this time though because of home entertainment systems, video-on-demand, and legal and illegal movie downloads. Towards the end of the Golden Age, around 1955, the fascination with 3D was starting to be lost. There were a number of reasons for this, one of the main factors was that in order for the film to be seen in 3D it had to be shown on two reels at the same time, which meant that the two reels had to be exactly in time else the effect would be lost and it would cause the audience headaches. Chapter 6: Occasional 3D films (1960 2000) Between 1960 and 2000 there were sporadic resurgences in 3D. These were down to new technologies becoming available. In the late 1960s the invention of a single strip 3D format initiated a revival as it meant that the dual projectors would no longer go out of sync and cause eye-strain. The first version of this single strip 3D format to be used was called Space-Vision 3D, it worked on an over and under basis. This meant that the frame was horizontally split into two, during playback it was then separate in two using a prism and polarised glasses. However, there were major drawbacks with Space-Vision 3D. Due to the design of the cameras required to film in this format, the only major lens that was compatible was the Bernier lens. The focal length of the Bernier optic is fixed at 35mm and the interaxial at 65mm. Neither may be varied, but convergence may be altered'(Lipton, 1982).This obviously restricted the creative filmmaking options and as a result was soon superseded by a new format called Stereovision. Stereovision was similar to Space-Vision 3D in that is split the frame in two, unlike Space-Vision though, the frame was split vertically, and they were placed side-by-side. During projection these frames were then put through an anamorphic lens, thereby stretching them back to their original size. These also made use of the polarising method introduced by Land in 1929. A film made using this process was called The Stewardess, released in 1969, it cost only $100,000 to make but at the cinema it grossed $26,000,000 (Lipton, 1982). Understandably the studios were very interested in the profit margin that arose from this film. As a result 3D once again became an interesting prospect for studios. Up until fairly recently films were still shot and edited using old film techniques (i.e. not digitally). This made manipulating 3D films quite difficult, this lack of control over the full process made 3D less appealing to film makers. The digitisation of post-processing and visual effects gave us another surge in the 1990s. But only full digitisation, from glass to glass from the cameras to projector lenses gives 3D the technological biotope it needs to thrive (Mendiburu, 2009). Chapter 7: The Second Golden Age of 3D (2004 present) In 2003 James Cameron released Ghost of the Abyss, it was the first full length 3D feature film that used the Reality Camera System, which was specially designed to use new high definition digital cameras. These digital cameras meant that the old techniques used with 3D film no longer restricted the work-flow, and the whole process can be done digitally, from start to finish. The next groundbreaking film was Robert Semeckis 2004 animated film Polar Express which was also shown in IMAX theatres. It was released at the same time in 2D and 3D, the 3D cinemas took on average 14 times more money that the 2D cinemas. The cinemas once again took note, and since Polar Express was released in 2004, 3D digital films have become more and more prominent. IMAX are no longer the only cinemas capable of displaying digital 3D films. A large proportion of conventional cinemas have made the switch to digital, this switch has enabled 3D films to be exhibited in a large range of cinemas. CHAPTER 8: 3D TECHNOLOGIES 8.1 3D capture and display methods Each different type of stereoscopic display projects the combined left and right images together onto a flat surface, usually a television or cinema screen. The viewer then must have a method of decoding this image and separating the combined image into left and right images and relaying these to the correct eye. The method that is used to split this image is, in the majority of cases, a pair of glasses. There are two brackets of encoding method, passive and active. Passive means that the images are combined into one and then the glasses split this image in to two separate images for left and right eye. In this method the glasses are cheaper to produce and the expense usually comes in the equipment used to project the image. The second method is active display. This method works by sending the alternative images in a very quick succession (L-R-L-R-L-R), the glasses then periodically block the appropriate eye piece, this is done at such a fast rate that it appears to be continuous in both eyes. There are various different types of encoding encapsulated within each of the two methods mentioned above. The encoding can use either colour separation (anaglyph, Dolby 3D), time separation (active glasses) or polarisation (RealD). A separate method, which does not require the use of glasses is done by using a virtual space in front of the screen and is called autosterescopic. In cinemas across the world at the moment there are several formats that are used to display 3D films. Three of the main distributors are Real-D, iMAX and Dolby-3D. Once a 3D film has been finished by the studios, it then needs to be prepared for exhibition in various different formats, this can include amongst other things colour grading and anti ghosting processes. At present there is not a universally agreed format for capturing or playing back 3D films, as a result there are several different versions, these are explained below. A large majority of the latest wave of 3D technology options send the image using one projector, so removing the old problem of out sync left and right images. The methods that do use dual projectors are much more sophisticated that the older versions used in anaglyphic films so have eradicated the old problems of out of sync projectors. 8.2 Gho
