Communication & professional relationships with children, young people and adults Essay

1.1 In order to develop a positive, professional relationship with a child, it is very important to communicate effectively in your dealings. This means learning how to approach and respond to children. Positive relationships go hand in hand with successful communication of information. Adults within a school who deliver information strongly and effectively are more likely to be beneficial to pupils. Good communication skills involve watching and censoring what we say in times of stress or excitement so our behaviour is not copied and the school expectations are upheld. If we set boundaries and ask a child to behave in a certain way, then we ourselves cross those boundaries, then it is harder for that child to understand what is acceptable and what is not. Good and effective communication must be worked on or misunderstandings may happen, leading to bad feeling and sometimes un-repairable working relationships. 1.2Â  There are several principles of relationship building with children, firstly effective communication; this is a key area in developing initial relationships. Secondly showing respect to a child and listening to their point of view will in turn earn respect and you should always take time to remember their names. Another principle is being considerate and taking into consideration that a child maybe under stress which may have affected their behaviour in the short term. Maintaining a sense of humour is another key principle as laughter is a great way to relax and relieve stress. It is important to always take time to listen as a child may need to confide or ask advice. Showing interest develops relationships. Principle number six is to always remember personal issues and inquire from time to time and show concern, this makes a child feel cared for and will relax more in your presence. Finally being clear on key points and when speaking to a child and relaying information is important, ask the child to repeat what you just said so that it is clear that the child understood at the end of your discussion. Relationships in school are built on a daily basis, by following these key principles you can build a good rapport with children. 1.3Â  To communicate with pupils from a different cultural background it is important to adapt your behaviour to suit the situation; for example a child from a different country may require you to speak slowly and concisely enabling that child to understand easily and take an active part in the conversation. In some cultures it is considered to be impolite to look somebody in the eye whilst talking to them therefore it would be necessary to adapt how we behave by adhering to their practices.

Marketing Review Essay

You track sales and profits, and discover that pants are selling better than shirts, apparently because the shirts are too expensive. You will look for a lower-cost supplier for shirts, or consider dropping your prices if you can afford to do so. 2. You realize that your experience as skaters is a plus; however, your lack of experience in selling clothing could hurt you. You find out that a skateboard shop in town wants to branch out into inline skating; however, you also find out that Nike is thinking about expanding its product line to include special inline skating clothes. 3. You decide that you will target college students who enjoy inline skating, and will aim to establish yourself as a company that offers trendy clothes for the student budget. 4. You decide that your business focus will be to offer fashionable yet durable clothing for inline skaters, with built-in protection for knees and elbows. 5. You offer clothing that college students would want to wear, price it for a student budget, sell it online and in sports stores near college campuses, and promote your products on Facebook. 8. As the text explains, Nike, the prominent athletic shoe manufacturer, relies heavily on athlete sponsorships to build demand for its products. Spectators at major sporting events–both those attending in person and those watching at home–frequently see the Nike â€Å"swoosh† logo worn by elite athletes. Given the vast worldwide audience for Olympics broadcasts, an Olympic year gives Nike increased exposure. On a Nike situation analysis in an Olympic year, would you consider this exposure to be a strength or an opportunity? Explain your reasoning; be specific. Nike, the prominent athletic shoe manufacturer, acquired Cole-Haan, a manufacturer of dress and casual street shoes, in 1988. Depending on your interpretation of the products and markets involved, you might be able to argue that this acquisition represented any of the four major growth strategies. For EACH of the four growth strategies, offer a justification that the Cole-Haan acquisition represented that particular strategy. Don’t just define what the growth strategy means; apply the definition to this specific example. Once you have offered a justification for each of the four growth strategies, choose the one you think the Cole-Haan acquisition best represents, and explain why. Subway is a large chain of franchise sandwich shops. Marcia owns three Subway stores in a large city. At the end of the year, she notes that sales rose from two to five percent over last year’s sales at Stores 1 and 2, but fell two percent at Store 3. Marcia decides to give large bonuses to the managers of Stores 1 and 2, and to put Store 3’s manager on probation. Critique Marcia’s evaluation of her stores’ performance. What would you have done differently? Be specific. Question marks: low market share/high growth rate. Candidates for strategic marketing planning, assessing potential for growth. 2. Dogs: low market share/low growth rate. Candidates to be phased out unless they are needed to complement or boost sales of other products. 3. Cash cows: high market share/low growth rate. Sources of funding for other parts of the firm. They typically require modest promotional and production support. 4. Stars: high market share/high growth rate. Usually require continued promotion efforts and expansion of production capacity. 136. The two bases of classification are relative market share (high-low) and market growth rate (high-low). This leads to four quadrants labeled stars, cash cows, dogs, and question marks. 137. Your sales manager wants you to stop selling those products that are in slow growth markets and which the company has a small relative market share. The manager also wants you to spend more time and effort selling products that are in high growth markets and which the company has a high market share. Finally, you should continue to sell but not put additional effort into high relative market share, low market growth products, referred to as cash cows. If Ryan pursues a market development strategy, he will attempt to serve new market segments. Since his product is a restaurant, market development would likely include opening additional locations in other areas, offering the same menu. 138. If Ryan pursues a market penetration strategy, he will likely expand advertising and promotion, maybe adding billboards, promoting specials, adding hours and likely expanding the restaurant to serve more customers. If they pursue a diversification strategy, they would market new products or services to a market segment they are not currently serving. Targeting landscape design or maintenance services for commercial customers would be one type of diversification. 139. If they pursue a product development strategy, they will offer new products or services to the firm’s current target market. A nursery could logically provide a landscape design consulting service, landscape maintenance service, soil and pest testing service or add additional products such as indigenous plants. 140. Many elements might be included, but it is important for students to demonstrate they understand the importance of allocating resources, leveraging competencies, capitalizing on strengths and minimizing weaknesses, coordinating efforts and decisions, and facilitating smooth operations for the firm. 141. Firms operate in a complex environment, and it is easy to overlook critical issues in the overwhelming possibilities. A structured approach will minimize the possibility that important items will be overlooked. It is also a way to ensure the transparency for the rest of the organization who depend on marketing for leadership. 142. Operational excellence, because it focuses on efficiency in its supply chain. 143. Creating and developing customer value. 144. Summer–planning; Fall–implementation; Spring–control. 145. SWOT analyses help a firm evaluate the current situation, both the internal environment and external environment. 146. Opportunities that build on a firm’s strengths relative to those of their competitors. 147. Market penetration, because the companies are trying to sell additional products (marked down) to current customers. 148. Product development, because the CD is a new product (just recorded) and it’s being sold to current customers. Some students might say that it is a market development strategy. For this to be correct, they would have to argue that a different market segment that currently doesn’t drink orange juice is being targeted. 149. The best answer is that this is a market penetration strategy. The slogan seeks to increase sales of a current product (orange juice), which reduces the options to market penetration or market development. â€Å"It isn’t just for breakfast anymore† sounds like the Growers Association wants those who drink orange juice at breakfast time to consider it at other times of the day too. In other words, it focuses on increasing usage among current customers, which is market penetration. 1. Locational excellence: In addition to having a top-notch website, try to get your products into as many retail stores as possible, probably focusing on sporting goods stores. 2. Operational excellence: Develop close relationships with suppliers of fabric and other raw materials and with retailers. 3. Customer excellence: Offer outstanding service, perhaps including live chat on the website as well as no-hassle returns if the customer changes his or her mind about a purchase. 4. Product excellence: Focus on continually improving the products and making them the most advanced ones on the market, perhaps using stylish yet durable fabrics that won’t be damaged in a fall. Then work to develop a clear positioning statement for your brand. 150. There are many correct answers; here is a sample. To make this question easier, you could ask the student to provide an idea for just one or two of the macro strategies. 1. Threats-could include the recession, a glut of graduates in the field, or reduced demand for professionals in the field 2. Opportunities-could include expected growth in the field, a new firm starting up in the area that will be hiring, or a shortage of graduates in the field 3. Weaknesses-possibilities include lack of experience, inability to relocate, or a low GPA 4. Strengths-students might mention internship experience, past work experience, classes taken, personal characteristics, or personal contacts Students will come up with a variety of answers depending on their individual situations. They will probably need to do some speculation for Opportunities and Threats. Here is a sample: 151. In order to make sure the students clearly classify the factors, you might want to provide an answer space with four sections; in each one, include a blank line for the name of the section and additional space for the factor. If you want to make this question more difficult, you can add to the question the following: â€Å"What should Microsoft have done before deciding to discontinue the product?† The answer: Microsoft should have determined the causes for the disappointing sales in order to determine whether or not another action (perhaps a different target market, a price adjustment, or a revised promotion plan) could put sales back on track. Some students might also answer â€Å"Control phase.† Strictly speaking, this is a phase and not a step; however, Step 5 is the only step of the process that fits into the Control phase, so you may want to accept both as correct answers. 152. Step 5–Evaluate performance using marketing metrics. 153. A. Evaluate results; B. Situation analysis; C. STP; D. Business mission; E. Implementation 154. A reasonable argument can be made for this being a strength or an opportunity, so this is about the rationale offered. This could be viewed as a strength in that Nike’s logo is ubiquitous and well-recognized, and customers in Nike’s target markets will be reminded of the many sports for which Nike offers shoes and apparel. It could also be viewed as an opportunity to strengthen Nike’s position overseas (due to international viewership) and to increase awareness of the breadth of Nike’s products (due to increased viewership of niche sports that ordinarily don’t get much attention). This question helps to point out that classifications are rarely black and white–how things are viewed depend on assumptions. Diversification: If you argue that dress/casual street shoes represent a different type of product from athletic shoes, but that different customers would buy Cole-Haan’s dress shoes from those that buy Nike athletic shoes, then the Cole-Haan acquisition enabled Nike to sell new products to new markets. Product development: If you argue that dress/casual street shoes represent a different type of product from athletic shoes, and if you argue that Nike’s customers would also purchase dress/casual street shoes, then the Cole-Haan acquisition enabled Nike to sell new products to its current customers. Market development: If you argue that shoes represent one type of product regardless of the type of shoe, but that different customers would buy Cole-Haan’s dress shoes from those that buy Nike athletic shoes, then the Cole-Haan acquisition enabled Nike to sell its existing product (shoes) to new markets. 155. Market penetration: If you argue that shoes represent one type of product regardless of the type of shoe, and if you argue that Nike’s customers would also purchase dress and casual street shoes, then the Cole-Haan acquisition enabled Nike to sell more of its existing product (shoes) to its current customers. 156. The major problem with Marcia’s evaluation is that her only point of comparison seems to be last year’s sales figures. She should attempt to obtain information on sales trends at other Subway sandwich shops, and if possible, at competing sandwich shops in her city. For example, perhaps her competitors and/or fellow franchisees saw much larger gains, perhaps due to an improving economy. She should also seek to understand whether or not there might be an explanation for the reduction in sales at the third store. Perhaps it is located in a shopping center that has been losing tenants, which would be beyond the manager’s control and therefore shouldn’t factor into a performance evaluation. ch02 Summary Category # of Questions AACSB: Analytic 158 Blooms: Analyze 5 Blooms: Apply 52 Blooms: Evaluate 9 Blooms: Remember 23 Blooms: Understand 69 Difficulty: 1 Easy 23 Difficulty: 2 Medium 82 Difficulty: 3 Hard 53 Grewal – Chapter 02 158 Learning Objective: 02-01 Define a marketing strategy. 40 Learning Objective: 02-02 Describe the elements of a marketing plan. 17 Learning Objective: 02-03 Analyze a marketing situation using SWOT analysis. 14 Learning Objective: 02- 18 04 Describe how a firm chooses which consumer group(s) to pursue with its marketing efforts.

Is it accurate to describe the Global Justice Movement as a 'global Essay

Is it accurate to describe the Global Justice Movement as a 'global movement' - Essay Example For instance, the global character of these emergent social movements reflects the contemporary movement of ideas, information, products, and people. The movement of people outside national borders are viewed as outbursts of aspirations, and by itself, they are considered integral to sociological analysis (Goodwin & Jasper 2009). The French sociologist Bourdieu (2001 cited in Ruggiero 2002) asserts that governments should meddle with the rules running the economy. At the same time, he emphasises the appearance of new kinds of political movement, and new forms of organisations driven by self-supervision, and â€Å"characterised by a structural lightness allowing agents to reappropriate their role as active subjects† (Ruggiero 2002: p. 48). These present-day social movements are described to develop precise goals, to take on kinds of activity of high representative character, to be global, and to demand highly dedicated personal involvement from members, and to form themselves a s freely organised systems (Della Porta & Diani 2006). The Global Justice Movement exhibits almost all of these features. This paper tries to determine whether it is accurate to describe the Global Justice Movement as a ‘global movement’. The Contemporary Global Movement The initial years of the 21st century were a period of hope and enthusiasm for many people across the globe. A new form of social movement was developing. Driven by the dialogical and varied networks of protest envisioned by the Zapatistas, an array of popular movements and militant-directed non-governmental groups, maybe mostly but absolutely not totally from the global North, were banding together to form a mobilization of movements opposed to neoliberal globalisation (Eschle & Maiguashca 2005). Some of them are enemies of the World Trade Organisation, World Bank, and the International Monetary Fund; supporters of global finance capital taxation; critics of the strengthened control of multinational en tities; proponents of debt assistance for Third World countries; and detractors of capitalism motivated by different expressions of socialist and revolutionary principles. Nevertheless, the 9/11 attack and their consequences have raised difficult challenges to the GJM. The social significances connected to the terrorist attack in the U.S., the legitimisation of militaristic nationalism forces and the accompanied transformations in the political arena of global governance have merged to change the political setting where in the movement works (Amoore 2005). In this environment of terror and nearly unanimously exercises of U.S. power, mechanisms of political, social, and economic de-territorialisation which had reinforced the development of global movements may be more and more re-expressed in nationalistic ways (Mayo 2005). Whether the Global Justice Movement is capable of calming the neo-imperial rage, holding back the powerful drag of nationalisms, and thus preserving its thrust to wards a more unified, peaceful, and just global order remains unresolved. There are major similarities between the current global anti-war movement and GJM. These similarities attest to the fact the GJM is indeed a ‘global movement’. Primarily, a great deal of the anti-war movement has taken on GJM’s very effective network framework of global grassroots political movement feature. Second, organisations and leaders integral to the GJM have turned out to be strongly involved in the anti-war move

APEC impact on China's economy Essay Example | Topics and Well Written Essays - 500 words

APEC impact on China's economy - Essay Example ipation in APEC meetings, China wants to demonstrate its desire for maintaining the regional economic stability that can bring prosperity to the member countries of Asia Pacific region. The resistance to the temptation of Yuan devaluation and announcement of tariff rates reduction by Chinese government at a meeting of APEC in Osaka has confirmed this. Through this action, China perceives the opportunity to deal with United States by joining hands with East Asian countries, which are also members of APEC.(Yang & Huang 70) As APEC was the first international economic conference to member nations, under the Chinese leadership of president Xi Jinping, China has used this platform in an efficient manner, in the direction of seeking bigger economic role, globally. This combined with the fact that Chinese economy is the world second largest gives the required advantage to China for countering US economic domination. In this direction, China has announced the established of US Dollar forty million fund for improving the trade and economic links among Asia-Pacific countries. The emerging image of China being the top trading partner of South Asian countries from South Korea to Australia would definitely help in the erosion of American influence on these countries. (McDonald & Lee) Earlier APEC could not prove to be result-oriented for the members, as it failed to improve the economic relations among the Asia-Pacific nations in a substantial manner. However, when China hosted the APEC conference, it made clear to the member nations that the country was prepared to share the fruits of its economic development with neighbors in the region. For ensuring that APEC remained a successful platform to deliver the results. China made many announcements, which include the commitment from China to donate ten million US Dollars towards supporting the capacity building and institutional activities of APEC, apart from establishment of Silk Road fund for undertaking the infrastructure

Visit a community agency or family support services Essay

Visit a community agency or family support services - Essay Example As far as this local community agency is concerned, it is being run by an elderly gentleman who believes in the premise of imparting services to the people who deserve them the most. I was astounded to know that he collected donations from people through his own efforts and did not have any proper funding mechanisms in place. This made his place within my heart even more because he was doing all this out of his own hard work and commitment (Dror, 2002). I understood that this gentleman derived the funds for the local community agency through donations since he visited different schools, colleges and universities to ask the students and teachers for the funding. He also visited people who were of repute and had a certain standing within the society. I am of the view that this money was being used in a very corrective fashion since he gained due insight at using the funds and thus knew how to turn little amount of resources into solid results. What is even more interesting is the fact that the local community agency is being run by a complete management committee which reports to the director (the gentleman under question). This management committee makes sure that the different processes and activities are being solicited and run in an amicable fashion so that there are no apprehensions as such, and the end results are very positive from the long term scheme of things. My mind opened up when I saw a small place turning dreams into realities (Crichton, 1997). I envisioned how success could be reached upon if there is good will and determination applied to the same. This gave me comprehension that I can work there and learn the true essence of life as it was important for me as far as the future domains were concerned. The observations and analysis of this local community agency are important to list here. Patients had a very positive outlook for the local community agency and they came to it with the hope that either they will recover or their family members woul d see the light of the day at the earliest possible moment. They had inkling and a ray of hope that the local community agency would help solve their problems and would in essence offer them a cost-effective and even a free solution to make sure that their issues get resolved. They would be relieved of their ailments and illnesses which were plaguing them as I personally contacted one of the patients who had come to the local community agency. She told me that she and her entire family had been visiting the local community agency for the last 2 years as this was the most affordable local community agency in the whole area. She told me she did not have enough money on her to pay for the rising medical costs of the time. I also analyzed that the courteous behavior of the medical staff was something that worked very well with the people who had visited the local community agency. The patients and their accompanying guests were grateful that the local community agency’s medical s taff had a positive mindset and that they looked after them in a very hospitable way (Dawkins, 2007). I am glad that I visited this local community agency to gain a good amount of understanding because it created empathy within my personality and told me how I could be accountable for my actions and behaviors if seen from a very moral perspective. I am happy that I learned all this stuff very quickly and

Interpersonal Conflict in Film Movie Review Example | Topics and Well Written Essays - 500 words

Interpersonal Conflict in Film - Movie Review Example Farhad did not know anything about guns and so when the store owner asked him about the kind of ammunition he wanted, Farhad had an argument with Dorri. This made the owner impatient and he told Farhad: â€Å"Yo, Osama, plan the jihad on your own time, what do you want?† Because of this statement, Farhad reacted: â€Å"Are you making insult at me?† The store owner continued in insulting Farhad and he said: â€Å"Is that the closest you can come to English.† Farhad emphasized that he can speak English and that he has rights to buy a gun: â€Å"Yes, I speak English. I am an American citizen†¦I have rights to buy guns!† Then the store owner reminded Farhad about 9/11, which made Farhad angrier. The owner called the guard, which led Farhad outside the door, while Dorri was left inside the store to demand either their money back or that the owner give them the gun. The conflict was not handled effectively, because the store owner and Farhad both had negati ve stereotypes about each other, which they used to prejudge each other’s motives and actions. Stereotypes are â€Å"preconceived opinions† about someone that tend to be â€Å"negative and reflect prejudices, preconceived opinions of dislike, hostility, or unjust behavior† (Sole, 2011, section 7.2).

Argument essay of Epistemology Assignment Example | Topics and Well Written Essays - 1000 words

Argument essay of Epistemology - Assignment Example ing to epistemology focuses on philosophical analyses on the particular nature of knowledge including its relationship with other connected notions like justification and true belief. Many philosophers have raised question of whether the concept of knowledge needs any king of justification for it to be accepted as being true and reliable. It is important to understand that when it comes to epistemology, knowledge that is discussed is often propositional, also referred to as the â€Å"knowledge that.† this kind of knowledge is often separated from the â€Å"knowledge how† as well as â€Å"acquaintance knowledge.† For instance, it is a well known fact that when you add 2+2=4; however, another kind of knowledge often exist like that of knowing another person of oneself, place or something (Comesaà ±a, 2005). This has made some philosophers to suggest that an important distinction exists between â€Å"knowing how,† â€Å"knowing that† as well as â€Å"acquaintance knowledge.† In all these, epistemology seems to be greatly interested in the second one. In this paper, I have attempted to make an argument of whether knowledge that people have over various subjects can be effectively justified. For a long time, justification has often been regarded as one of the major conditions for knowledge. In this case, the theories that have long been used to deny the reasons for justification have often been dismissed as being mere non-starters. Previously, some philosophers had attempted to make the traditional perspective that justification was indeed an essential and necessary condition in the study and understanding of knowledge. This was contrary to the epistemic externalists that suggested that justification was to be replaced and in its place, a more reliable indication that was quite sensitive or any kind of externalist condition. The initial philosophers explained that the concept of replacement was not needed at all, since it was not very necessary. Soon this views were

Screening journals Essay Example | Topics and Well Written Essays - 500 words

Screening journals - Essay Example The song itself has an overall feel of R&B mixed with hip-hop or electronic dance due to the low vocal ranges of the song, the use of a hook and repetitive melody and lyrics, which are not usually heard from songs by Beyoncà ©. However, despite the R&B shell of the song, it delivers a strong, feminist message based on the cultural background of people of color, namely Beyoncà © and featured artist Chimamanda Ngozi Adicihe and their cultural backgrounds as female African-Americans in modern US society. Such ideas are exemplified by the melodic lyrics â€Å"I took some time to live my life/ But don’t think I’m just his little wife† sung by Beyoncà © and a section of the spoken lines by Adicihe: â€Å"But why do we teach girls to aspire to marriage/ And we don’t teach boys the same?†(Knowles, 2013). Based on the context, the lyrics contain the message that female African-Americans are only taught of such things and not allowed to have and live their own aspirations, ideas that are strongly-questioned in the song and are subjects of criticism as well. The video may seem confusing for some due to the combination of new and old elements, with the beginning and endings showing an old talent show clip and the song itself showing a dance club where Beyoncà © dances along with other people, as well as the inclusion of lyrics within the music video itself. However, despite seemingly-contradictory elements of the song, the opening and ending parts of the video are able to convey the message of needs for equality and feminism clearly, as it was seen in the last part that the male Caucasian-American group won by a star over the African-American female group, suggesting the societal bias against races considered to be the minority. These components can be observed and understood fully by viewers if they viewed the video from start to finish, and as such all elements (lyrics, vocal, visuals) are needed to convey

Leadership and Management in Nursing Research Paper

Leadership and Management in Nursing - Research Paper Example No doubt, Nurses in superior clinical practice incorporate education, research, management, leadership, and consultation into their clinical role.

Arab world Article Example | Topics and Well Written Essays - 750 words

Arab world - Article Example (2007: p 364) Same is the case with the Arab world, which maintains its unique ethnographic identity, historical background, ancestry, cultural traits, social norms, moral values, religious beliefs and genealogy. The people speaking Arabic as their primary or first language are called the Arabs. â€Å"The Arab world†, Tamari views, â€Å"is not to be confused with the â€Å"Middle East,† a strategic designation developed during the heyday of the British Empire, which encompasses such non-Arab countries as Israel, Iran, Turkey, Pakistan, and Afghanistan. And though Arab history is intertwined with Muslim history, the Arab world does not correspond to the Muslim world.† (Quoted in ccas.georgetown.edu) At present, the total Arab population, inhabited in twenty three countries of the world, has been estimated to be about 325 million with 2.3% annual increase. (UNFPA 2007) The have been articulated divergent propositions regarding the origin and background of the Arabs. One school of thought declares that the Arabian Peninsula is the origin of the Arabs, and the Bedouin clans of that region are the forefathers of them, who had been living there far before the birth of Abraham in Babylonia. The first positive reference to the Arabian extant occurs in an inscription of the Assyrians, Shalmaneser III, who speaks of the capture of a thousand camels from Gindibu, the Arabia, in 854 B. C. (Landau, 1958: 11-21: quoted in bible.ca) In addition, It had mistakenly been considered that all Arabs are the descendents of Ismail (Ishmael) the elder son of Abraham. The basic source of this information is the Semitic religions and a large majority of the Abrahamic religions, including Jews, Christians and Muslims, view Ismail as the father of the Arabs. According to the Jewish sources, it was Ishmael, whose descendents were blessed and multiplied as a great nation: â €Å"God heard the boy (Ishmael) crying, and the angel of God called to Hagar from heaven and said to her, "What is the

International Relations Theory Essay Example for Free

International Relations Theory Essay The study of the international relations has traditionally focused on the study of the causes of war and conflict between the states and the condition of peace. However, in the 21st century we are more concerned with the question of how the global relations can be identified, and with who lays the power of world politics. The global politics and international relations concepts have been developed over centuries. The key theories have established the commonly accepted methods of explaining the relationships between the states, and the way in which nations conduct their businesses. We can distinguish between many strands of thought, each extensive and often mutable. Thus, it is hard to define which are the most equitable and had most leverage in the international relations or global politics. However, we can certainly highlight few, which are seen as the most important or even crucial. One of them is Marxism, developed by Karl Marx in the 19th century. Marxism sought to purport the varied terrains in a new and unprecedented way. Some of the key aphorisms include the materialism, class system theory, the dialectical approach to history and of course a critique to liberalism and capitalism. Alas, the Marxism theory was precluded in the 1990s, after the oppression of people, economic instability, poverty and unhappiness under the communistic rule became evident. However, in the latter years of extreme economic and social crisis, many scholars once again engaged in the critical insight of capitalism, just as Marx did centuries ago. Marxism is the only theory available, which seeks to completely undermine capitalism, and expose its fundamental flaws which capitalists try to avoid or divert, but cannot overcome. However, it is not only limited to the economics. It presents extensive explanation of social and political relations and ways in which societies can determine it. It offers a new concept of freedom, far more expansive and empowering than the traditional liberal understanding. In this essay I will critically assess the extent to which Marxism has contributed to an understanding of the global politics. The global politics otensibly consists of many strands of scholar thought , analysis and theories . The acuurate and cognizant way of explaining or arranging the different approaches would be to put them in two categories; mainstreem and the rest. The parenial mainstreem theories of international relations are realism, liberalism, neo-realism and neo-liberalism. Other vail approaches share much with mainstreetm but have been seen rather as develpoments or critiques or of it, often providing a very distinct analysys . One of such is Marxism. Karl Marx developed new depiction with some linkages to the previous theories. He offers a distinct approach and analysis of political, social and economic life. Marx’s aim was to expose the hidden truth about the world of politics, and to higlight to people that history, politics and our social life is not something that only happens to us (independently from our actions), but rather something wich happens with our presence and input, and therefore can also be transformed by us. We can choose weather or not we want to live in a political-social system which we inherited, or to alter it if we are dissatissfied with it. In this sense politics appears as a struggle over processess of social-self production. The ability to steer various processess in one direction or another, thus shape the world in whcih we live in, produce a social change. Marxs expalins this as a dialectical or process orientated approach to understanding our history and politics. The historical tensions and cirumstances opneded up various possibilities for actors (agents embodied in institutions), to produce a change. As humans we have a freedom or in other words a collective ability to shape ourselfs and our world. This concept of freedom is broader and more empowering , than in the traditional liberal thinging (freedom of choice, our wants and needs in the market). Another important aphorism of Karl Marx was historical materialism. According to Marx all life is constantly evolving . The evolution results from the clash of two opposing forces. The same must happen with peolpe. For centuries humanity experienced struggles and clashes mainly between 2 groups of people. In the acient world it was the slaves and the lords, in the middle the peasants (surfs)and the lad owners, and in capitalism the capitalists (burgouise) and the working class (proletariat). Each historic era is different , has its own dynamic an dlogic, based on a dominant mode of production: primitive, feudalism and finally capitalism. For Marx each stage had its beginbing, middle but also an end. Marx also belived that history is shaped by the material basis of society. He recognised base and superstructure division of society. He included education, politics, religion, culture, media to the superstructure. Underneeth the superstructure there lies base consisted of relations of production (burguoise), and means of production everything which is owned by burguise needed for procution such as technology for instance). The base in Marx view , creates a particular type of political authority which is mostly concerned with protecting and promoting the interests of the dominant class. The base can change the history and the society. The key implication here is that the people who conctrol the material base (the means and forces of production), ulitmately control the society, politics and the world we live in. He recognised tha states as the puppet of a dominant class. Marx also offered an extensive and profound crtique to caqpitalism, imperialism and globaloization. He did not undermined it. It is fair to say that Marx understood capitalims as the most productive theorey that every existed but nevertheless, he recognised that it was living on a borrowed time. For Marx the capitalism had fundamental flaws as it was exploitative and oppressive system. He examined the features of capitalism, praised it for the competetive nature whihc would recsult and many spohisticated advancemnts, presented its flaws and atributes. Karl Marx acknowledge that constant urge for profit wouldstimulate the innovation process in various fields such as technology, media, medicine. Nevertheless, the necessity to generate higher and higher profit is the main downfall of the globalization and capitalism concept. As a result capitalism will move from crisis to criris, and the society will become increasingly unequal. Marx specified that capitalists will attempt to reslove one crisis, but as one problem would be resolved, another would be created in its place. We can clearly see how this process works taking for instance the sub-prime lending case. As people did not have enough money , the demand failed. The profits of various cooperations also failed (as demand stimalates the supply and the prices). The banks offered creditd cards and loans. In turn people bought more goods, and contributed to the economy. Everyone was happy in the process, the baks, the producers and of course the working class who would now finally buy the goods and services they wanted. One problem was solved. However, after a while people did not meet their repayments. The banks had to confiscate their houses, cars, and other possesions as a result. Now banks were left with empty houses, and a huge deficit of money. The enterpreneours who invested and supplied banks with the money lost a vast ammount of money, many bankrupted. The taxes rates for the lower and the middle were risen, and the wages cut so the capitalists could once again make profit. Alas, less wages and bigger taxes meant less dissposable income to pay for the new good and services. The capitalists once again have to battle low profits, and find new ways to stay in business, The whole process reapeats itself, and no concrete and reliable solution is found. Marx also crtiticises the globalization process. The global capitalism means alliances of globalised capitalists, in order to do the business together and gain more control. This aspect of globalization within the context of capitalism will also prove fatal, as the interconcetivity between various world economies could potentiall bring doom to all if one falls ( we can see it happening with the hyousing bubble burst in the USA, resulting from the sub-prime lending . This crisis not only affected the USA economy, but spreaded to the rest of the world resulting in the global economical crises and recession). Marxs posited that economic relations between people was core to absolutely everything. The human needs for housing, security, food, drive human interactions. Furthermore he stasted that private property divided the world. The human persistency to barter and to create profit was a recepie for distater. Capitalism develpse productive powers of human societies, but it does in rather undemocratic manner, through exploating and subduing the working class. As a result it distors the real historiacal possibilities for social self-determination. Socially empowered people under the capitalistic system, are prevented from realising their full productive powers and enjoying their fuller forms of freedom. Under tha capitalism ideaology supports the historiucally specific forms of social activity and organization, which appears to be necessarry and natural universal conditions. It takes on the apperance of unchangable, and hard-wired withing the society. This is of course mistification. Within the context of capitalism , we are isolated individuals, therefore we confornt our social envirometn not as collective product. We views it in terms of constraint on our individual chocies. This way of understanding social relations as parennial, universal and natural prevents us from looking for possibilities of transformation, or imagining the alternative possible worlds. Marxism inspired future analysis in the international relations arena . One of the most significant was the crtitical theory. The critical theory was develpoed in 1930s by the frankfurt school of thoutgt. The term frnakfurt school refers to theorists originally assosiated with the Institute for Social Research at Frankfurt University . The early frnakfurt shcool tehorist Horkheimer and Adorno, began too lose faith in the revolutionary potential of the proletaria. The also saw how in the west Marxism was marxism was being transformed into a doctrisn of economic determinism. In the face of these developments, they wanted to retain a critical modern critical and potentially progressive role for social theory, but were wary of the orthodox Marxisms’ preocupation with production and the coresponding emphasis on the historical role of the proletariat† The core concepts of the Crtical theory are that critical social theory should be directed at the totality of society in its historical specificity , and also that critical theory should improve understanding of society by integrating all the major social sciences, including geography, economics, sociology, history, political science, anthropology, and psychology. Critical theoriests developed a key concept that the objectively valid forms of knowledge could not be established independently of the social context and social norms. The theories which claimthat they provide objective truth are profoundly misleading. In their view idealogy (or theories assosiated with it), are just a belief that oue perspective is the truth. The way in which things appera from the economic standpoint of our consciousness. They asked a question: can idealogy be proven, is it just a mode of belief. After all idealogy is without conciousness. Is it fair to say that things actually are the way they appear to me? The frankfurt scholars went on explaining that in each historic period the dominant class sets the idealogy. In the late capitalism it is ultimately a burgouise idealogy. So the ideas whic are the base of every aspect of our society , (for instance our current work ethic or current standards of moral behaviour) do not have to be universal, just and correct. The frankfurt scholars have undermined the positivist forms of scienfitic knowledge. They claim that positivism and instrumental reason discourse denys the alternative values and future possible worlds. Gramsci went a bit further and develpoed a theory of hegemony as a form of political power whcih relied upon the consent than coercion. â€Å" In a hegemonic social situation, dominant groups (classes, class fractions and their verious alliers) articulate a social vision which claims to serve the intersts of all, and they use selective incentives to recruit junior partners into their coalition and to didivde the disable oposition† He belived that in modern and advances capitalistsic societies, hegemonic power might be promoted via media, education, art, literature as well as political parties. Under these conditions various groups might be led to consent to the powerof dominant groups. This action would make the use of obviously opressive and coercive power unnecessary.. He also argued that hegemony should be continously chalenged by the civil society. In this way he hoped that capitaslist culture would be challenged by a counter-hegemonic political culture. In short, he speculated that peolpe might start to think of their economic lives as having a significant political importance . Gramsci hoped that they might finally question the universal capitalism’s structured separation of the ploitical fromt he economic aspects of life. Another important approach to global politics, which derives from Marxism is the World systems theory , which was fathered by Immanueakl Wallestein in the 1970s. He traced the rise of the world system to the 16th century Western Europe, whihc then spraded to the rest of the world. The E3urope feudal economy suffered crisi and was transformed into capitalism. The west quikly utilisised their advantages and gained control and power, over the most of the world economy (using colonialism, slavery, imperialism and globalisation together with the unfair trade). This actions resulted in an unequal develpoment, which instead of diminishing grows even further. Wallestein also supported Marx’s previous view that the suposely tree distnict areas of politics, socio9logya nd economics are in fact combined. In his writing Wollestein provided a structural explenation of the global inequallity between states. He viewd it as a pyramis. At the top of the pyramid lye the core states. Whuhc dominate the system. They all are in favour of capitalistic global economy for their own elevation. Examples in todays world inlude USA, Japan or Western Europe. Beneeth the core states lys the semi-periphery states, which are seeking to elevate themselfs to claim their place among the core . Examples include the BRIC countries: Brasil. Rusia, India or China. At the very bottom of the pyramid lies the peripher, the weakest of the states (third wolrd countires ). They are usually rulled by the puppet goverments , subservient to the global capitalists. Ruled by the core states. They will never be given the standars of life they deserve through their inustry. They usually provide most of the natural resources and products which are greedly devour by the core, only to recive poor technoplogy and ocasional aid in return. People in the third world countries (peripherians) are the main victims of this opression, as they benefit less from the spohisticated technology and innovation that capitalism (through drive for profit) brings about. This generates a fundamental innequality between the nations. Conclusion The forms of Marxian critical theory (further develpoed by the Frankfurt school and by Gramsci), lead us to a conlusion that the claims of scientific objectivity assosiated with positivistiv theories of International relations are in fact profoundly misleading . This approach differs a lot from the mainstreem realistic and liberalistsi approaches of the international relations. More recently there has been a sort of renaissance of Marxian international theory. It began during the 1990s and gained its momentum with the US war on terror after the 9/11/. The American war on terror is seen by many as the twnety-first-centuray imperialism . Many scholars return to Marxism wirtings and its later developments, to find it very accurate in the sphere of the global politics today. Undoubtedly, Marxism contributed in large means to our understanding of the global politics. It is the only reliable source of the critique of the capitalistis system we currently live in. Furthermore it explains and provides an analis of it. It stresses the interdependence of social-political- and economical aspects of life , not only within the domestic arena but also on the global scale. Marxisms highlights the global innequalities that the capitalism creates, demonstrates and unmasks the constant exploitation and mannipulation of the working class. It stresses the importance of all idvividuals, and their ability to transform and alter the world around us which includes our political system, current moral and ethical forms of behaviour, the ecoonomic system and every other aspect of our live. Marx and the later scholars influenced by his writing, do not propose a new clear system to replace capitalism. The presumptions are left to us . Within the concept of marism the idealogy can always be altered, it shall not be seen as something parenially just and fair. It is also seen as the tool of the higher class, who usess it to explain the world to the lower class and further to control it. Therefore Marx saw idealogy only a way of explainign and understanding the world rather than verity. This approach had big significance in the global politics theory. It inspired new starnds of thought in international relations and of course met with a fierce critique of positivistic scholars and thinkers.

German Essays Enlightenment and Religious Tolerance

German Essays Enlightenment and Religious Tolerance Enlightenment and Religious Tolerance in Gotthold Ephraim Lessings Die Juden and Nathan der Weise. Because of the impact of the intellectual revolution, the eighteenth century is frequently referred to as the Age of Reason. More specifically, the term Enlightenment is used because a major feature of this era was the minds emphasis on using rationality as a framework within which to view major philosophical issues. According to Benson and DiYanni, the Enlightenment continued an emphasis on secular concerns that began during the Renaissance and continued with the rise of scientific and philosophical thought during the seventeenth century (2005: 397). During this epoch, superstition came to be replaced with logical thought and analysis. These influences can be seen in the works of Gotthold Ephraim Lessing. Lessing is considered by many to be a major representative of the Enlightenment Era. He was well known as a dramatist, critic, and philosopher during this time frame in Germany, and his works remain popular and influential even in contemporary times. In terms of religious tolerance, Lessings philosophies are perhaps best represented by two of his dramatic pieces, Nathan der Weise, or Nathan the Wise, and Die Juden, or The Jews. According to one scholar, these two plays by Lessing are instructive examples that demonstrate, when read in light of the historical specificity of their context, the force of critical thinking that drove Lessing (Goetschel 2003: 63). Lessings impact is still felt today. According to Garland, The Jews had shown [Lessings] deep antipathy to the unreasonable hatred directed against that people (1962: 191). In the eighteenth century, the ideas introduced by the Enlightenment had far-reaching effects on Western society. In fact, many of those ideas remain influential to this day. Formerly, much of Europe had been plagued by archaic prejudices towards those whose religious faith was considered to be a minority. This theme is nowhere more evident than in Lessings plays, Nathan the Wise and The Jews According to Goetschel, both of these works are evidence of Lessings critical concern to rethink both the claims of Christianity and the groundwork of modern national identity (2003: 63). Gotthold Ephraim Lessing was born in the quiet country town of Kamenz. His father, Johann Gottfried Lessing, was an educated man, but he was not wealthy. He worked as an assistant pastor in Kamenz It was from him that the younger Lessing got his love of books, something that would last throughout his life. Lessing attended the University of Leipzig. Leipzig was a new world for the young man. It was far different from Kamenz. In fact, it was sometimes known as Little Paris because of the level of sophistication that existed there (Garland 1962: 7). Lessings early literary works included Damon and The Young Scholar Neither of these works gave any indication that Lessing would eventually come to be known as the father of German literature, although The Young Scholar enjoyed a brief spate of popularity on the stage. During his youth, Lessing exhibited a tendency to rebel against the status quo. This became particularly clear during his college days. Correspondence between him and his parents shows evidence of a young man of great curiosity, and one for whom a tried and true path would not suffice. His parents wished the best for him, naturally: a steady career that would bring him stability and a modest amount of comfort. It was also hoped that Lessing, as the eldest, would establish himself in order to contribute to the education of his younger siblings. However, this was not the path that Lessing chose to follow. His adventurous spirit, combined with his youth, and the atmosphere of Leipzig, all combined to determine a path that would veer from his parents wishes. These experiences led him to become a thinker and writer who was ahead of his time, as well as one of the finest minds of the German Enlightenment. Lessings Plays: Nathan the Wise and The Jews. In many ways, Nathan the Wise can be considered a play that was ahead of its time. According to Wilms, this play is canonized not just in German literature, but also in the liberal Enlightenment reception of that literature and its tradition (2002: 306). The central theme is the concept of brotherhood among mankind. Through the vehicle of drama, Lessing puts forth the message that people should be able to exist in harmony despite their religious denomination or group affiliation. For example, it should not matter whether one is a Jew, a Christian, or a Muslim; people should respect each other and coexist peacefully no matter what religious affiliations they have. Lessings primary message in Nathan the Wise is that the main consideration should be the value of individuals as human beings, and that group membership is secondary to this. This is the concept that the character of Nathan proposes. The role of money in this play merits some attention. Lessing uses money as a prop and as a theme. It is an integral part of the discourse of the play. According to Graham, from the first moiment of the pla we are never allowed to forget Nathans association with money and the desirable goods that money can buy (1973: 179). Money, and the power of money, are apparently very important to Lessing here. It is also significant to note that Nathan is rarely the recipient of money. He is rather, the giver. The suggestion that Nathan is wise may play a role here. This may be yet another way in which Lessing underscores the value of giving rather than receiving. As Graham notes, the religious impulse of surrendering the grateful self to the giver of life reverberates in every one of these situations, in varying degreees of consciousness, and in every instance soemthing of the same release of love is experienced and communicated (1973: 185). It can be said that the true villain of Lessings play is the insidious hatred that is passed down from one generation to the next. This hatred is a complex mixture of mistrust and ignorance and is so deeply ingrained in people that often it remains unquestioned, simply a part of life. Nathan the Wise is often considered a vehicle in which Lessings theological beliefs are given voice. Lessing believed in freedom of thought and was a serious student of theology. In some ways, it appears that Nathan the Wise is a mixture of various theological ideologies, many of which also appear in Lessings Erziehung des Menschengeschlechts, or Education of the Human Race, which was published in 1780. According to Wilms, in Nathan the Wise, rationality successfully overcomes a series of obstacles and works its way into a traditional Lebenswelt dominated by prejudice that does not shy away from murder and even genocide (2002: 306). The triumph of rationality here is a central theme of Lessings work. He takes on the traditional themes of religious dogma in this play and shows how individuals can take a rational approach to them The title of the play refers to the main character, Nathan. The play takes place in Jerusalem, where Nathan lives as a prosperous Jew. The time frame is in the twelfth century. In the play, it is significant that Nathan adopts an orphan. The orphan happens to be Christian, but this does not matter to Nathan, who simply takes her into his home because she was the daughter of a friend. Immediately we see that Nathan is the kind of character to rise above petty details, and to act in the interests of humanity above all else.   Considering the time and setting, this is certainly no ordinary act. Tension builds, however, when a suitor comes into the picture. Nathan is aware of the inherent danger in this situation. Should the identity of his adoptive daughter be made known, the results would most undoubtedly be tragic for all involved. This use of hidden identity was common in the literary works of Lessings time, and it is used quite effectively in this play. Ultimately, Lessings message in Nathan the Wise is that humanity is far more important than religious affiliation. Lessing asserts that the worth of people should not based on what religion individuals are born into, or on blood relations, but rather on the very fact that they are human. According to Garland, anti-Semitism had lessened somewhat, but was still considered widespread during the period of time in which Lessing was writing. The theme of the play is that people cannot be judged by their religious affiliations. The plot of the play is simple, ostensibly to allow the theme to stand out. The character of the Baron is clearly full of strong anti-Semitic prejudices. Therefore, when he is attacked by robbers, he immediately concludes that the perpetrators were of the Jewish persuasion, in keeping with his beliefs. It is of course ironic that the attackers are found to be Christian. Furthermore, they are employees of the Baron himself. As for the noble Stranger who rescues the Baron, he is revealed to be Jewish himself. This puts the Baron in a rather awkward situation, as he has promised the hand of his daughter to The Stranger in return for his gallantry. Of course, once the Stranger has identified himself as a Jew, the wedding is now unthinkable. According to Garland, Lessings interest is clearly centered on the serious aspects of the play The moral is pointed not only by the action, but is also underlined by frequent passages of dialogue (1962: 111). Here, as in Nathan the Wise, Lessing effectively uses the tactic of the hidden identity to elucidate his point. Once again, the message is that humanity is far more important than religious affiliation. In The Jews, Lessing asserts again that the worth of people should not be based on what religion individuals are born into This is quite apparent when it turns out that the Barons attackers are in fact the very servants on whom he relies. The person who saves him, The Stranger, turns out to be a Jew himself, which adds to the irony. Lessings attitude to orthodoxy is rather complex. Much of his beliefs in his early life were strongly influenced by his friend, the freethinker Mylius. Mylius befriended him in Leipzig. Several years older, Mylius had a great deal of influence on his young protà ©gà © In a letter to his father, written when he was twenty years old, we can see the evolution of the young Lessings thoughts about religion: Time will prove whether he is the better Christian, who has the principles of Christian doctrine in his memory, and on his lips, often without understanding them, who goes to church and observes all the practices (of religion) just because they are customary; or he who has once prudently doubted and has reached conviction by the path of investigation, or at an rate strives to reach it. The Christian religion is not a thing which one should accept on trust from ones parents (quoted in Garland 1962: 151). Seeds of unrest and a pull towards independent thinking are apparent even at this early stage in Lessings development. We can already see this tendency to be skeptical of church-goers whose actions are at odds with their stated beliefs. As stated earlier, anti-Semitism was somewhat less pronounced during this period, although it still clearly existed. The idea that people should not be judged by their religious affiliations seems to have already taken hold in Lessings young mind. According to Garland, Lessing was struck by the obvious divergence between the doctrine of Christ and the mode of life of many of those who passed as Christians (1962: 152). He was very much aware of the hypocrisy inherent in many who claimed to be Christians. Even as a young man, he was easily incensed by intolerance towards religious practices. He seemed to have little respect for orthodox theologies that had little room for the beliefs of others. In the eighteenth century, as discussed earlier, the ideas introduced by the Enlightenment had far-reaching effects on Western society. In fact, many of those ideas remain influential to this day. Formerly, much of Europe had been plagued by archaic prejudices towards those whose religious faith was considered to be a minority. Conclusion The period of the Enlightenment in Europe signaled a change in thinking. As representative pieces, these two plays by Lessing are examples of these new attitudes towards religion. Because of the impact of the intellectual revolution, the eighteenth century is frequently referred to as the Age of Reason. More specifically, the term Enlightenment is used because a major feature of this era was the minds emphasis on using rationality as a framework within which to view major philosophical issues. During this epoch, superstition came to be replaced with logical thought and analysis. These influences can be seen in the works of Gotthold Ephraim Lessing. A recurring theme in the works of Lessing is the concept of brotherhood among mankind. Through the vehicle of drama, Lessing puts forth the idea that people should be able to exist in harmony despite their religious denomination or group affiliation. Whether one is Christian, Muslim, or Jew, is irrelevant Ones connection to a particular religious group should not affect the basic respect that people should feel for one another. People of different faiths and beliefs should respect each other and coexist peacefully no matter what religious affiliations they have. Lessings primary message in Nathan the Wise is that the main consideration should be the value of individuals as human beings, and that group membership is secondary to this. This is the concept that the character of Nathan proposes. This message is also present in The Jews Here, as in Nathan the Wise, Lessing once again makes it clear that humanity is far more important than religious affiliation. In The Jews, Lessing asserts again that the value of a person should be independent of what religion that person is born into. This is quite apparent when it turns out that the Barons attackers are in fact the very servants on whom he relies. The person who saves him, The Stranger, turns out to be a Jew himself, which adds to the irony. Lessing, as we have seen, is considered by many to be a major representative of the Enlightenment Era. He was well known as a dramatist, critic, and philosopher during this time frame in Germany. The fact that his works remain popular and influential even in contemporary times is a testament to his ongoing influence. In terms of religious tolerance, Lessings philosophies are perhaps best represented by these two dramatic pieces Each of these works is an example of the critical and independent thinking that drove Lessing from his early days at university in Leipzig and throughout his life. Lessings impact is still felt today. As discussed above, the ideas brought to the fore in the eighteenth century had a tremendous impact on Western society. The concepts introduced during the stage known as the Enlightenment had far-reaching effects. In fact, many of these ideas remain influential to this day. Many of the prejudices that had been formulated regarding religious affiliations were analyzed and found to be wanting. This theme is nowhere more evident than in Lessings plays, Nathan the Wise and The Jews. Lessings messages in both of these plays call into question both the claims of Christianity and the significance of the underlying national identity. Many people consider Lessing to be a major representative of the Period of Enlightenment in Germany. His influence is felt in many spheres: he was well known as a dramatist, critic, and philosopher during this epoch, and his works remain popular and influential even in contemporary times. In terms of religious tolerance, Lessings philosophies are perhaps best represented by two of his dramatic pieces, Nathan der Weise, or Nathan the Wise, and Die Juden, or The Jews In each of these plays, Lessing makes clear his belief that people should not be judged by their religious affiliations. In Nathan the Wise, we find a complex mix of ideologies. These same ideologies are present in The Jews, although to a lesser extent. It can be said that the true villain in each of these plays is the insidious hatred that is passed down from one generation to the next. Lessing portrays this hatred as a complex mixture of mistrust and ignorance that is so deeply ingrained in people that often it remains unquestioned. Both Nathan the Wise and The Jews can be considered vehicles in which Lessings theological beliefs are given voice. In the eighteenth century, the ideas introduced by the Enlightenment had far-reaching effects on Western society, and those effects are elucidated in these dramatic works. Much of Europe had been riddled with archaic prejudices towards those whose religious faith was considered to be a minority. Lessing focuses on these prejudices in an effective dramatic format. In terms of religious tolerance, Lessings philosophies are strongly represented by these two dra matic pieces. In the eighteenth century, the ideas introduced by the Enlightenment had far-reaching effects on Western society. In fact, many of those ideas remain influential to this day. For readers today, these works continue to have an impact. Both of these plays offer a close look at the evolving attitudes towards religion and society of that era.

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.

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
