Cognitive Science, In The Study Of How Organisms Process Information A

Cognitive science, in the study of how organisms process information as well carry out life functions. The study of Cognitive science is said to have been originated in the 1940's and 1950's when researchers in various fields of science began to develop theories on the mind based on complex representations and computational procedures (Thagard, Cognitive Science). There are numerous branches of science whose theories contributed to the development of Coginitive Science. These subdivisions include cybernetics, theoretical computer science, linguistics, experimental pyschology, and neuroscience. Cybernetics, a term used by Norbert Wiener is the study of control and communication in animals as well as machines (Lu, Definition of Cognitive Science). Some key events that took place in the 1940's and 50's within the branch of cybernetics that contributed to the advancement of Cognitive Science were two article's, Behavior, Purpose and Teleology by Arturo Rosenblueth, Norbert Wiener, and Julian Bigelow and A Logical Calculus of the Ideas Immanent in Nervous Activity by Warren McCulloch and Walter Pitts both published in 1943. These articles discussed regulatory processes. These articles stimulated conferences about Circular Causal and Feedback Mechanisms in Biological and Social Systems and took place between the years of 1944 and 1953. To many, one of the most important events in the development of Cognitive science took place in 1948. This was the year that Norbert Wiener published his book Cybernetics (Jogasurya, Origin of Cybernetics). Alan Turning was an english mathematician heavily involved in the development of theoretical Computer Science. In 1936, Turing invented what is known as the Turing machine. A Turing machine is hypothetical device that represents how computation is done. All computational processes can be abstractly described using a Turing machine. Linguistics is the scientific study of language. Before the 1950's, linguistics was broken down into two main catagories, historical linguistics and structural liguistics. Noam Chomsky, an American linguist played an important role in the development of linguistics. Chomsky founded transformational-generative grammer. Transformation-generative grammer is a highly influential system of linguistic analysis. Because of Chomsky and his contributions, the behaviorsits accounts of language were challenged, human computations became the focus for liguistics, and focus was directed away from how grammer's are learned to how grammers are a mental 'organ' (Andrews, The Birth of Cognitive Science)

My odessius is a hero essays

My odessius is a hero essays Odysseus is a man that embodies the general aspect of an epic hero but does not seem to have the morals of a hero. He fights in an unfair manner, lies to his crew, and he kills for no apparent reason. (Repetition) Odysseus is Superman to the Greeks. (Metaphor) Try to imagine Superman fighting one of his numerous archenemies. Superman fights fair like the bigger man (simile), no matter what. After defeating the monster Superman does not kill it, but takes it to some place that it can live without it hurting others and then he does not lie about what he does. To begin, a hero fights on the side of fairness and would never lay traps to ambush an injured enemy. That would be like Superman breaking someones legs and then challenging them to a fistfight. This is in reference to Odysseus blinding the Cyclops and then taunting them as the beast lays reeling in pain. Then on the way out, Odysseus taunts the blinded enemy again, basically challenging him. This shows Odysseus lack of ability to fight fair. This is not a quality of a hero, epic or otherwise. Second, Odysseus lies to his crew by not telling them of the impending danger. Instead of telling his men he lies and lets the monsters take his crew by surprise. Think of your self in that situation. Row, Row. By the way, duck, there is a huge monster behind you that I forgot to tell you guys about. Would a hero lie and not tell his men about danger? Of course not, all classic heroes always give their people a choice when facing death. Odysseus appears to be acting like a coward and deceiving his crew into following him. Finally, a true hero only kills his enemy as a last resort. Odysseus, after twenty years at sea, comes home to find his wife holding a contest with suitors for her hand. After winning the contest he stands on a table yelling that he will kill them all. We would never think of Superman, someone thought to be hero, yelling that he would kil...

Marketing concept Essay Example | Topics and Well Written Essays - 500 words

Marketing concept - Essay Example This means they should be given the room to understand what the product/service shall bring for them more than anything else. The marketing concept aims to pinpoint the needs of the target consumers and addresses the same whilst meeting their very needs through the purchase of the product/service and its ultimate usage. If there is no selling of the product, there would be no association of the need with the target audience and hence marketing might not be needed at all. Thus marketing concept looks to solve the problems in which the consumers are tied up and even when there is no problem at all – just to satisfy one’s desires – they are asked to purchase a product/service so as to have a better standing within a particular social circle or society. In other words, this encompasses the basis of self-esteem needs if not anything else (Varey 2001). Successful examples of marketing include the campaigns that have been launched by Coca Cola all over the globe. The pr oduct exists within the minds of the target audiences but even then the company has to market it on a consistent basis (Marco, 2001). This is for the fact that Coca Cola exists and it wants to make a mark on the consumers’ minds at every possible instance.

Pupil Voice in the learning institutions Essay Example | Topics and Well Written Essays - 5000 words

Pupil Voice in the learning institutions - Essay Example The intention of this study is the pupil voice as the consultative wing of pupil participation. When we talk of consultation, it means talking with pupils about things that matter in school. These may involve: discussions about teaching and learning, seeking of advice from pupils about new initiatives; calling for comments on ways of solving problems that affect the teacher’s right to teach, as well as, the pupil’s right to learn. It also entails calling for invitation on evaluation comments on current developments in the schools or classroom policy and practice. Hopkins as in Education Resources Information Center states that the Pupil Voice and the active engagement of pupils in shaping their own educational experience are key items to the success of the joyous achievement that every child aspires. There exists an ideal condition for learners to enable pupils to enjoy and achieve their endeavors at school, be it in the classroom, or within the school compound. Therefo re, it is highly crucial that the necessary environment is availed to them to be able to achieve to their best and excel in their quest for knowledge. According to Jackson in nexus magazine, not all learning happens in classrooms, but it is profound that most of it happens inside the learner. The pupil voice being a tool that can effectively influence the learning process has been faced by various issues that have crippled it. It has been remarkably effective in the sense that, not all voice is included in the process. Various reasons have been associated with failure of inclusion in the pupil voice. Few voices are heard in the process of discussing issues pertaining to the school learning activities. One of the key drivers behind eliciting pupil voice has been the rights movement whereby children are seen to be vital contributors to the process of decision making around the provisions of services (Lewis and Porter, 2006).

Effect of Technology Development on Entertainment

Effect of Technology Development on Entertainment Table of Contents (Jump to) Introduction Delivering superior content Enhancing user experiences Platform mobility Conclusion References Introduction Over the years, the advancement of the digital technology has created a revolution in TV. Nielsen’s 2012 report stated that the number of homes with high definition TV grew in the US by more than 8 million (Nielsen 2011). This suggested that TV continues to be the dominant platform media for many households. Watching live or time-shifted TV programmes or games connected online via Internet are now using more of this conduit to deliver their contents to the many TV users. The continuous development and advancement in the digital technology continue to make a tremendous impact on television, playing an important part of family lives’ by offering quality entertainment and increasing the way of family bonding. They are achieved through delivering superior content, enhancing the user experiences’ in watching TV and offer excellent platform mobility for both network producers and users. Delivering superior content With the advancement of technologies like streaming video, high-quality video and Internet, it has offered different delivery platforms to deliver TV programs and dramas. However, the real focus remains on the content. In Kelly Scott Madison’s State of media report, it reiterated that â€Å"content is and always will remain, king† (Madison 2013). With quality programming content like ‘Who is HBO’s Girls for?’ (Smith 2012) that shows about different women and their lives, the show has differentiated itself from other media programming content. The show not only caters to mostly female audience demographics where most females are at home watching TV; the audience are able to relate their lives to the series show and this creates the ‘stickiness’ to the television drama series because of its content. This is similar to other shows like â€Å"Sex and the City†. Subscription TV penetration of TV households in Australia is increasing over the years. It is forecasted to increase from 30% in 2008 to 35% in 2017 (Maurer, Emmanuel Parker 2013). Through subscription TV, it provides different content and choices to the viewers like sport, movies, cartoons, variety shows. It also allows, through digital set-top boxes, the viewers can record and view the program as and when he prefers. This is not available in the traditional broadcast TV when the viewers have to watch a show through a fixed schedule. The regulatory environment for free-to-air television in Australia continues to change. In 2012, the Convergence Review highlighted the need for diversity in media and more Australian content (ABC News 2012). With digital and primary channels, it allows broadcasters the flexibility to provide more Australian content. (Cosgrove, Schaffer Horlin 2013) Through digital technologies, viewers can watch ‘live’ broadcast shows like Formula-1 racing, AFL, English Premier League or Australian Open Tennis. In most networks, it also allows viewers to have video-on-demand in which the viewer can select the movies at their own convenience. Viewers can also use time-shifting features in their set-top to skip the advertisements if they would like to. Thus, with superior content and rapid advancement in technology, TV providers and networks can create more value to the TV consumers (Maurer, Emmanuel Parker 2013). Consumers will now spend more hours watching TV and be willing to spend more money in subscription or video-on-demand fees. Enhancing user experiences TV has advanced tremendously in recent years because of digital technologies advancement. From traditional black and white or colour TV, it now has features like high definition multimedia interface (HDMI), Dolby surround effects to 3D technology offering real-life effects to viewers. In addition, in the digital era, TV has provided more connectivity with other devices such as Nintendo wii or Xbox 360 game machine, Internet access for online games, music and many more. Many of these devices provide multi-user games that allow family members to enjoy playing the games in the living room together. Imagine the effects on family bonding when parents and their children can enjoy a game of tennis for several hours in front of the television in the living room. Through technologies, TV has created a ‘cocooning impulse’ (Tryon 2012, p. 291) that unite families and brings them together (Cosgrove, Schaffer Horlin 2013), creating bonding and harmony in the family. User experiences are also enhanced through the superior content delivery through digital technologies. Movies are more readily available in household TV through Pay TV or Subscription TV options. TV drama series like ‘Serangoon’ made by Australian TV or Lena Dunham’s ‘Girls’ are some examples where these sitcoms series which are made for television (Mundell 2013) have created a ‘glueing’ effects on user experiences to the TV. Technologies like video-on-demand and built-in program recorders of TV show allows time-shifting, thus watching TV becomes a ‘pleasure and a treat’ for housewives (Venkatraman 2013). Statistics have also shown that users are now more than doubled spending time watching time-shifted TV using their DVR (digital video recorder) (Madison 2012). Interactive TV also allows viewers to interact with other viewers through polls, chats, online shopping or voting. 3D technology in TV has now experienced a worldwide resurgence together with high definition video capability and superior sound quality standards. It also brought about a drastic change in television viewing, creating vibrant three dimension and captivating real life effects on the viewers. This has created a ‘3D revolution’ (Uniyal 2012) in the user experiences watching TV at home and not only in cinemas. Technological innovations in 3D technology for TV offer a more interactive television user experience through captivating user interfaces like 3D animations or real-time interaction with online apps like Facebook and Twitter (Connected Media World 2013). Platform mobility Traditional scheduled television broadcasts and viewing through receive-only television sets have been increasingly supplanted by digital technologies offering viewer engagement and convenience through video-on-demand, viewing of television programs across a multitude of devices such as smart mobile phones, Apple iPad tablets, Smart Internet-Ready Television, and sophisticated digital set-top boxes provided by cable and internet television operators. As pointed out by Sterne, people can spend many hours of their time watching specific programs using their mobile devices and still not realizing and thinking of themselves ‘as watching television’ (Sterne 2012). Tyron defines â€Å"platform mobility† as the â€Å"idea that films and television shows can move seamlessly from one device to another with minimal interruption† (Tyron 2012). He also noted that digital delivery technologies allowed workers and families with hectic schedules, the ability to watch television programs ‘wherever and whenever they would like’ (Tyron 2012). This provides them the individual and personalized experiences that cater to their own tastes and needs, enhancing the overall compelling user viewing experiences. Tyron (2012) further argues that the viewer empowerment through digital technologies has an overarching impact on viewer engagement as more mobile devices like iPad tablets, laptops and smartphones can provide the platform mobility to the users. Members of the family can watch different or same television program in different places within the house. This also empowered individual viewer to access to a wide range of choice selection like viewing on-demand movies on personal mobile device, online chat using social media applications such as Twitter and Facebook or speaking with their friends on their mobile phones while watching a sport game. Platform mobility also allows producers like Warner to sell their films through this mode of digital delivery to viewers who can purchase them via iPhone apps. Viewers can choose to view their favorite movies as and when they would like, in the living room or on a bus. Thus it can be said that the resurgence of TV as a home for â€Å"quality† entertainment can be partly attributed to demand spawned by viewers’ mobile and digital era lifestyles, and their desire to be an engaged viewer instead of being a passive one. Conclusion In conclusion, it is apparent that digital technologies will continue to remain a dominant force in the television industry as a home for ‘quality’ entertainment. TV network services providers continue to capitalize on the advancement of the digital technologies so as to explore and offer more innovative and value-add services to TV subscribers. Advancement in the Internet or other media delivery channels like satellite, broadcast via cable, allows service providers to increase their revenue streams by offering more superior content and options and enhancing user experiences by making use of newer technology like 3D. Platform mobility remains the focus of the future research in the digital technologies in the TV industry. This is because of the ever changing lifestyles and demanding needs of the younger generation for more contents and mobility. Hence, we will not see the demise of the television but rather a revolution that television plays an important part in the home for quality entertainment, through the digital technologies; and it continues to provide intrinsic value in family bonding.

Data Warehousing :: essays research papers

The company implementing the Data warehouse is Sears Roebuck & Co. Sears is in the retailing business selling ever thing from under garments to washing machines. The main reason why the company is implementing the DW is because it wants to maximize the use of its information in its credit data warehouse. The prior application processed steps sequentially one processor at a time thus not using the multiprocessor capabilities of its machine to process the huge quantity of data. Mining of data was too slow and could only be performed once a year, which produced inaccurate data for the Marketing department. Due to the meticulous process, other units of the company were barred from the data warehouse, which also cause dilemmas. Sears went to a consultant to solve the problem. The package chosen was the Torrent Systems Orchestrate Package. The reason for choosing this package is because the package fit the needs of the company to a match. It allows the company to convert its application from sequential to parallel by partitioning the data across the processors and running multiple, parallel instances of the application. The benefits from implementing the Orchestrate package is, the new program would examine account attributes like purchasing behavior and payment history, causing more lucrative targeted marketing campaigns and boosting sales and card balances. It will allow the job to be done at a fraction of the time of the prior system. In addition the new system increased the number of credit card accounts from 16 million to 22 million. Overall, from doing this case study I have learned that data mining and data warehouse’s are very important to all organizations especially very large organizations. DW’s help to further organize and use the data of the company to its fullest, which allows companies to operate more smoothly and efficiently. I gained a greater knowledge of DW’s and how they work and are used by organizations.

The Latest Developments of Air Transport

The commercial airline industry has grown from a few aircraft to that of a multi-billion pound industry. The Boeing 707 began a revolution in air travel when it entered service in1958.It was the first commercially successful jet aircraft. Since then aircraft manufacturers have strived to provide larger and more economical planes to aircraft companies. The basic appearance of commercial airliners has not changed much for over 50 years. Nevertheless, there has been a considerable increase in innovations and new technology within the aerospace industry. Advancements in engine efficiency, aerodynamics and new materials have all led to a significantly lower operating cost per seat mile of commercial aircraft. There have been a number of significant innovations, especially on the Boeing 787, the latest wide body jet to enter service. Composite materials are now been used in the commercial aircraft industry. The Boeing 787 is primarily constructed from composite materials. They are used in most primary structures, particularly the fuselage (see fig1). By using a unique one piece composite barrel construction, (See fig 2) the 787 eliminates the need for any fuselage lap joints, doubler longitudinal skin splices. This has a dramatic reduction in weight and drag. In addition, it also significantly reduces the amount of maintenance and inspections required. Panel construction in aircraft such as the Boeing 707 requires additional joints, fasteners and splice plates, resulting in increased weight and inspections. An example of a composite, which is used on the Boeing 787 is carbon laminate. It comprises of layers of carbon fibre that are impregnated with a polymer. Free Online Dictionary, Thesaurus and Encyclopaedia.. 2011. [ONLINE] Available at: http://www.thefreedictionary.com/composite+material. [Accessed 20th Novemberr 2011]. The use of composite materials ensures many advantages. They are lighter, stronger, do not corrode or fatigue, resist impacts better and are easier to examine during an inspection, compared with aluminium. Minor damage can be repaired at in less than an hour. Fig1 Corpu, (2007), plane [ONLINE]. Available at: http://www.google.co.uk/imgres?q=composites+on+aircraf [Accessed 01 December 11]. Fig 2 New Airplane, (2007), 21st Century Fuselage Construction [ONLINE]. Available at: http://www.newairplane.com/787/design_highlights/#/VisionaryDesign/Composites/OnePieceBarrelConstruction [Accessed 01 December 11]. The most critical expense areas for aircraft fleets are fuel, maintenance and its residual costs. New aircraft have been designed and manufactured to lower these costs. Maintenance tasks have been reduced by 30 per cent, and inspections are required less frequently. A good example of this is the 787 which does not require its first heavy maintenance check until after 12 years of service. Another advantage of using composite materials, especially in the wing structure is that it gives aircraft such as the 787 a higher aspect ratio than previous aircraft, resulting in a higher Coefficient of Lift. A lighter aircraft will reduce fuel costs and therefore have a positive effect on the range equation. Advancements in aerodynamics have led to an increase in the overall efficiency of aircraft, becoming more fuel efficient by reducing drag. Components such as winglets and wingtip fences decrease vortices created at the wing tips which cause aerodynamic drag. Winglets | Airbus, a leading aircraft manufacturer. 2011. [ONLINE] Available at: http://www.airbus.com/innovation/proven-concepts/in-design/winglets/. [Accessed 24th November 2011]. Raked wing tips create a greater degree of sweep on an aircraft wing. This enhances the wings efficiency, by increasing the aspect ratio of the wing, therefore decreasing the amount of lift induced drag produced by the aircraft. This kind of drag can be reduced by up to 6%.with the implication of raked wing tips. Blended winglets can be attached to the wing giving a level curve in place of a sharp angle reducing interference drag at the wing. Wikipedia. 2011. Wikipedia. [ONLINE] Available at: http://www.wikipedia.com. [Accessed 24th November 2011]. Riblet technology is a surface modification which consists of minute streamwise ridges and valleys, it has been proven to reduce local turbulent skin friction by up to 6 % . Houghton, E.L, 2003. Aerodynamics for Engineering Students. 5th ed. Oxford: Heinemann (book publisher). On the Boeing 767 double drooped slotted fowler flaps are used, whereas on the later 787 a simple hinged flap with drooping spoilers are used creating smoother wing technology. This results in a decrease in fuel consumption, weight, smaller fairings and fewer parts therefore reducing maintenance. Www.cdti.es/recourses/doc/eventosCDTI/Aerodays(2011) [pdf ]. [Accessed 24th November 2011]. Recently Airbus has completed the first flight of its A320 test aircraft equipped with ‘sharklet' wing-tip. The sharklets can cut fuel burn by up to 3.5% over the current configuration with wing-tip fences and increase the maximum take-off weight by up to 3 tonnes. The engine with the higher value of specific impulse (Isp) is more efficient because it produces more thrust for the same amount of fuel. A higher or more favourable L/D ratio is typically one of the major goals in aircraft design. Using these higher values will obviously increase the range of an aircraft. The latest propulsion systems have advanced, improving the economics of aircraft. Early jet airliners had turbojet engines. These engines operated well at high altitudes and speeds, but had had a high fuel burn rate. When the turbo fan engine was introduced it could move a greater amount of air at lower speeds, than the turbo jet engine, as it had a large fan attached on the front. By enclosing the fan inside a cowling, the aerodynamics was better controlled. This reduced fuel consumption, compared to a turbojet. The next-generation engine technology is provided by Boeing's engine partners, General Electric and Rolls-Royce. The latest engines being the Rolls Royce Trent 1000 and the General Electric GEnx. These engines incorporate a bypass ratio of about 10, compared to the first turbo fan engines having ratios of about 7. The higher bypass ratio allows the engine to be quieter, with significantly reduce fuel consumption. This lowers cost for the 787 operators and reduces emissions, lessening the environmental impact of the aircraft. Chevrons on the nacelles significantly reduce shock cell noise in the aft cabin. Both the Trent 1000 and the GEnx engines are interchangeable at the wing of the 787. This reduces operating costs and gives the 787 liquidity and strong residual value. Both the Rolls Royce Trent 1000 and the GEnx eliminate the engine bleed air system and associated pneumatic system. This improves the reliability and efficiency of the aircraft by further reducing fuel consumption and maintenance costs. The electric system improves efficiency by removing only the power actually needed during each phase of flight. The aircraft have a health management system which monitors the electrical systems, improving the aircrafts productivity. General Electric recently delivered a new innovation in technology producing advanced composite material fan blades .The process results in a 100% defect-free, carbon-reinforced epoxy blade , which means no voids in the fibres. In order to accomplish this, advanced sensor and data acquisition systems were used. This technology will continue to be used on wide-body aircraft of the future, Resulting in lower cost, and greater efficiency. Duncan, Tom, 2010. Engines of Today. Commercial Airliners, 2, 8. An innovation to watch out for in the near future is the use of Titanium aluminide turbine blades. Titanium aluminide’s low density means that a turbine blade will be about half the weight of a blade made from a traditional nickel alloy blades. Reducing the density and the weight of an aircraft engine has huge benefits. Materials of the Future – Online Stuff – Science Museum London . 2011.. [ONLINE] Available at:http://www.sciencemuseum.org.uk/onlinestuff/stories/materials_of_the_future.aspx. [Accessed 16 December 2011] Using the range equation you can calculate the range of an aircraft, if you have the value of the following components. R = distance flown (m) u = velocity (m/s) Isp = specific impulse (s) L/D = lift-to-drag ratio (dimensionless) Winitial = gross aircraft weight at the start of cruise (kg) Wfinal = gross weight at the end of cruise (kg) Houghton, E.L.H, 2003. Aerodynamics for engineering students.. 5th ed. Great Britain: Heinemann (book publisher) The engine with the higher value of specific impulse (Isp) is more efficient because it produces more thrust for the same amount of fuel. A higher or more favourable L/D ratio is typically one of the major goals in aircraft design. Using these higher values will obviously increase the range of an aircraft. The appearance of aircraft has not changed much over 50 years because when it was first designed the cone shaped fuselage with wings attached had good design and technology features. The process of designing and producing a new aircraft is very expensive and risky. There is enormous economic risk along with a large investment and liability risk. The (you bet your company curve) plot below shows the cumulative gain or loss in an aircraft project during its life. It was recently estimated that a new large airplane project at Boeing would take 20 billion dollars to develop. Origins of Commercial Aircraft. 2011. Origins of Commercial Aircraft. [ONLINE] Available at: http://adg.stanford.edu/aa241/intro/origins.html. [Accessed13 December 2011] Aircraft manufacturing companies are not likely to take risks on projects that rely on unproven technology. This is the reason that innovative concepts are not likely to be tried out on the next generation of commercial airliners and why aircraft such as the 787 look so much like the Boeing 707. Customers of commercial aircraft manufacturers can sell their planes which are basically the same appearance as 50 years ago. There is not enough financial gain to design an aircraft with a different appearance. In addition, passengers may prefer to board an aircraft that consist of a tube with wings rather than an aircraft in the shape of a large triangle. The new 787 Dreamliner is a prime example of how innovations in new airframe and propulsion technology can lead to a more efficient aircraft. From innovative composite materials to aerodynamics to propulsion technology the 787 has become 70% more fuel efficient than the 1950s-era four-engine Pratt & Whitney JT3D-powered Boeing 707s. This has considerably increased revenue potential through significantly better performance, improved fuel efficiency and lowered maintenance decreasing operating cost per seat mile of commercial aircraft.

Compare the Presentation of Change in Yeats”Sailing to Byzantium’

Compare the presentation of change in Yeats’ ‘Sailing to Byzantium’ and ‘The Second Coming’ Both of Yeats’ poems express his opinions and viewpoint of the changes in society and people’s beliefs. Through the poem ‘The Second Coming’ Yeats highlights his belief that the twentieth century had seen the beginning of a new darker era, full of violence and struggles for independence and the effects of the Great War. The second poem ‘Sailing to Byzantium’ expresses Yeats’ observations of old age and the comforting idea of travelling to Byzantium.Through the poem ‘The Second Coming’ reflects more than just society and politics within Ireland, but expresses Yeats’ turn of attention towards larger scale graphical and spiritual events such as The Great War in 1919. The Christian idea of the ‘Second coming’ that Christ would return is featured as the centre pin to Yeats’ poem a s questions what has become of his present day society, and how it had mutated and evolved from the more traditional, biblical times featured in religious stories and beliefs.The poem showcases Yeats’ acute understanding that a potentially dark time is ahead. The poem ‘Sailing to Byzantium’ features the theme of aging, a popular writing topic of Yeats’ also used in other poems such as ‘Wild Swans at Coole’. The idea of escaping the unaccommodating world and society of youth, and journeying to a calm Island of Byzantium appears a comforting thought. The poem written in when Yeats was around 60 years old provides insight into his thoughts of what it means to be old. The Second Coming’ contains links between how Yeats views society and the birth of Christ and the belief he would return. The first stanza of the poem contains imagery of violence and a lack of order. The phrase ‘mere anarchy’ highlights the main subject of the po em, the loss of a culture or civilisation, this dark imagery is used throughout the poem, ‘ Things fall apart; the centre cannot hold’ implies that the things at the heart of Yeats’ modern culture are literary and metaphorically broken.This change is described using natural imager of water; ‘the blood-dimmed tide’ and ‘the ceremony of innocence is drowned’ create a sense of fear as the natural power of water is uncontrollable, like the change Yeats is experiencing in the society of his time. This idea that the current society is not appropriate is shared in ‘Sailing to Byzantium’ as it is explained that it is ‘no country for old men’ and that ‘an aged man is but a paltry thing’, both phrases express the feeling of being out of place and unwanted ue to aging. Through the development of imagery such as ‘ the salmon- fall’ evoke the energy of youth whilst later ‘ a dying animalâ€⠄¢ contrast youth with age allowing Yeats to highlight the change from youth to experience with age. In the poem ‘The Second Coming’ Yeats uses the line ‘ the falcon cannot hear the falconer’ to give the worrying sense that nature is inverted and things are not as they should be, triggered by the coming change at the birth of a new era.The lines ‘The best lack all conviction, while the worst are full of passionate intensity’, built on opposites ‘best and worst’ again support the theme that the change has inverted life for the worst. The religious imagery of the birth of the ‘rough beast’, as it ‘slouches towards Bethlehem’ lacks an hint of human qualities, making it a stark contrast to the biblical, gentle saviour of Christ, but as a dehumanised monster. The use of stark contrast is also used within ‘Sailing to Byzantium’ between the differences of being young and old, ‘the young in one another’s arms’ carefree and ‘sick with desire’ of an aged man jealous of the youthful.The word ‘gyre’ in both poems is used as a common link to highlight to the reader that the changes occurring in both ‘Sailing to Byzantium’ and ‘The Second Coming’ are unavoidable and uncontrollable. While the technique of alliteration, ‘Bethlehem to be born’ in ‘The Second Coming’ supports the momentum and inevitability of change and the new era. Also ‘Fish, flesh, or fowl’ in ‘Sailing to Byzantium’ has a powerful effect as it recaptures all fish, youth and birds and brings them once again to the attention of the reader, as these three species are examples of youth and support the change experienced by the old.In conclusion through both poems Yeats expresses different types of change and the extent they have on people and society. While in ‘The Second Coming’ Yeats fo cuses on the worrying and almost threatening change in society through the twentieth century he highlights the also worrying, for different reason, inevitability of aging and the want to escape from the struggles of modern, youth controlled society.

Marriage equality and human rights violations Essay

Marriage equality and human rights violations - Essay Example The discrimination of the same sex marriage is a violation of human rights. President Obama accepted the same-sex marriage during the election campaigns which was controversial but helped in the achievement of the goal of re-election. According to the American president, the issue should be approached using the state to state approach. The advocating for a state approach to the problem would culminate in a national issue and finally lead to the success of the acceptance of the same-sex marriage. The impact of the approach would be different based on the legal implications of the problem. (Wolfson 23) The legal implications of the problem included a change in the legal direction of the country in relation to marriage and definition. Marriage equality is defined as same-sex marriage that is legally recognized in the society as the marriage between mature or adult persons. The major question posed by the proponents of the idea is based on the protection of human rights that is protected fundamentally by the constitution. The bill of rights stipulates the major issues that must be addressed in the protection of human freedom. Based on these freedoms including the freedom of association, it becomes challenging when defining marriage equality. Equality in marriage and marriage equality in the contemporary society means two different things today. Equality in marriage is the protection of the rights of individuals in marriage while marriage equality is the struggle to accept the new set of marriage partners resulting from homosexual and lesbian relationship in the society. In fact, the push for recognition has led to serious challenge in the society because of the resistance posed by conservatives (Casey 23). Despite the challenges in defining the term, it is widely accepted culturally to mean the relationship between same-sex partners and their intention to live together as a couple. Human rights violation in relation to marriage equality The protection of gay indivi duals in the society has been an issue of great concern. In fact, it involves the understanding of the bill of rights. However, despite the existence of the bill of rights, the acceptance of the same-sex marriage has been emotive issue and has led to various protests with an aim of seeking recognition. In fact, around the world, gays have conducted demonstrations seeking to be recognized and be accorded the necessary support compared to heterosexual relations (Olson 68). Consequently, a proposal by the conservative wing of the population believes that banning of the same-sex marriage could solve the already heated debate. However, it may create a more serious challenge as compared to the current problem. The freedom of association and relations will be affected in the event that the country decides to ban same-sex marriage (Pearson 6). Discrimination is the taking of the rights of the people by restricting or even denying people the right of association or relationship. The protecti on of gay rights in the society has been an issue of concern. They have been subjected to trauma and massive legal challenges.
