Argue against any common controversial position, such as supporting death penalty, or contemporary phenomenom, such as the disadvantages of online education - Essay Example A vast majority of religions, particularly the Abrahamic religions, consider both suicide and murder some of the gravest sins described by these religions. For example, killing one person is considered equal to killing all mankind according to Islam. Proponents of euthanasia say that euthanasia is not murder since the will of the victim is involved in it. In a vast majority of cases, this is not what happens. A lot of cases of euthanasia happen to people who are either mentally retarded, or are the patients of comma. In neither of these cases, the victim is able to decide for himself/herself. The decision is made by the relatives who are bearing the expenses of medical care of the victim. There are certain cases in which the personal will of the individual who is given euthanasia, is involved. From the religious perspective, this may not be a murder, but for sure is a suicide, which is again a grave sin. This sin is committed not only by the victim of euthanasia who opted for it, but also by the doctors who helped in making the victim’s wish come true. Therefore, religion condemns euthanasia whether or not the personal will of the victim is involved. From the ethical perspective, euthanasia is wrong as well. In the case when the victim’s will is not involved, ending his/her life is essentially a violation of his/her most fundamental right of living. Every human being deserves to live till the time of natural death. It is not for other human beings to decide when a certain individual’s life should be brought to an end. On the other hand, when the victim’s will is involved in euthanasia, giving him/her euthanasia is still unethical for several reasons. People opting for suicide are psychologically disturbed and overcome with distress and tension. The solution to their problems is medical help and psychological therapy, not euthanasia. If the individual is allowed to survive, his/her health might improve with the

Diversified in industries and electronics

Diversified in industries and electronics Introduction Initially, Samsung started out as a small export business in Korea. It then diversified in industries and electronics. The company has been responsive to change and opportunity in global business brought by the digital era with its constant innovation and attractive, marketable products.1 As a result, Samsung is now positioned as one of the world recognized leaders in the digital technology industry. The Samsung World Headquarters is located in Seoul, Korean. 1 History In 1938, founding chairman Byung-Chull Lee started a small trade export business in Taegu, Korea. In the 1970s, Samsung invested in the heavy, chemical and petrochemical industries as a foundation for future growth. Samsung also incorporated its manufacturing processes from raw materials to end products which further enhance its position in the worlds textile industry. Samsungs core technology businesses diversified and expanded globally during the late 1970s and early 1980s. Soon after, two research and development (RD) institutes were created. This boost its reach even further into electronics, semiconductors, high polymer chemicals, genetic engineering, optical telecommunications, aerospace and new fields of technology innovation from nanotechnology to advanced network architectures. In the mid-1990s, Samsung revolutionised its business aiming to make world-class products, provide total customer satisfaction and be a good corporate citizen. Samsung has constantly developed advance d technologies, competitive products and constant innovation 1. Main Technologies and Capabilities Main Capabilities Research and Development Innovation is at the heart Samsungs business success. To be competitive in the new digital age, Samsung maintains and strengthens its market dominance through the speedy introduction of new technology. The company has placed high importance to the interplay of creative, imaginative human resources, a global RD network, a strong collaboration among business partners all along the supply chain, and the commitment to ongoing investment. Currently, Samsung is making historic advances in RD of semiconductor products, especially flash memory and non-memory, custom semiconductors, DRAM and SRAM, LCDs, mobile phones, and digital appliances1 Eco Samsung Samsung has displayed its strong commitment and responsibility for the world environment. It has made efforts to develop environmentally-friendly products which consume low levels of energy and which contain no hazardous materials. The company has also modified its assembly processes to cut down carbon emissions substantially.2 Main Technologies Samsung comprises of companies that have become market leaders in a wide range of business, from electronics to financial services, from chemicals and heavy industries to trade and services. All the businesses are setting new standards in innovation, constantly generating high quality products and services.3 Owing to Samsungs large RD sector, many new technologies and innovative designs emerge. Below are a few of the newest technologies developed by Samsung. Main Markets, Products and Competitors Markets Samsung Group consists of numerous international affiliated businesses such as Samsung Electronics, Samsung Heavy Industries, and Samsung CT. These three multinational core businesses of Samsung Group signify their strong foothold in the electronics, shipbuilding and construction markets. Besides that, Samsung also plays a part in the financial, chemical, retail and entertainment markets. 1 Samsung reports a strong presence in its home country of South Korea as its market share in telecommunications is 18.87%. 1 Samsung appeals to the global market as it is the most popular consumer electronics brand since 2005 with 7.55% of global market share in telecommunications1. Products Samsung first started moving into businesses such as insurance, securities and retail. Later, upon borrowed foreign investments, Samsung ventured into the telecommunications industry with Samsung Electronics. With the support of South Korean President; Samsung developed the first dynamic random access memory chip. 1Most importantly Samsung are leading in the production of memory chips, chipmakers and liquid-crystal display panels. 1 Considered as a strong competitor in the world of electronics, Samsung highlighted innovative strategy and expanded production rapidly to become the worlds largest producers of DRAM chips, flash memory, optical storage and recently liquid crystal displays. In addition Samsung strives to improve by delivering innovative products such as the TV and monitor industrys thinnest LED TVs and most compact colour laser printers and multifunctional devices. Being a global leader in telecommunications equipment; Samsung plays the role in development of the next gene ration of 4G-network. 1 Competitors According to the Figure 1 below; Nokia is clearly the main competitor as it holds 37% of the mobile phones sales global market share. In 2009, Samsungs touch screen devices, QWERTY phones and smart phones drove sales in mature markets with 19% of the global market share7. LG poses 11% as a competitor as it moves into lower-tier devices which drive growth in emerging markets. It is also well positioned to take advantage of Chinas 3G Rollout as it can deliver good-value-for-money devices. Motorola has 11% market share which is reasonably smaller, however with its presence rapidly concentrated on the American it serves as a competition in the American market. Being in a competitive market, Sony Ericsson at 5% of the global market share attributes its poor performance to its uncompetitive range of handsets such as exploiting trends like QWERTY products. Therefore Sony Ericsson is a smaller competitor compare to Nokia and other phones such as Apple, HTC, and Blackberry. Nokia is Samsungs biggest competitor due to its early investments in GSM technologies therefore making the company into the worlds largest mobile producer manufacture. Up to date Nokia produced various innovative products such as the first 3G phones, Ovi internet services and N-series multimedia phone. Nokias revenue is reported to be 9.3 million Euros. 9 Its success is due to its high investment in the RD which is present in 16 countries, representing 31% of their total workforce. 8 Nokia phones are also seen as being highest quality as they have a highly recognizable packaging style which operates with an aggressive marketing strategy hence elevating them above their competitors. Samsungs Innovative Activities Samsungs ambition to become one of the worlds top companies is supported by continuous pursuit in innovative RD and building a distinctive brand. As stated in the Annual Report 2008, approximately 40 %( 42,100 researchers) of Samsungs global employees are involved in RD to develop cutting edge technologies1. Samsung Advanced Institute in Technology is the global hub of Samsungs RD organization which includes Mechatronics and Manufacturing Technology Centre and 14 overseas centres7. In 2008, Samsung obtained 3,515 patents in the US with an increase from 2007 placing them in second place in the annual patent ranking. To further push forward in a variety of market and customer focused brand marketing programs, Samsung successfully completed their role as the official wireless equipment partner of the 2008 Beijing Olympics and Paralympics Games. 7 In 2008, Samsungs investment of 6.9 trillion KRW which represented 9.5% of parent company sales brings in technological breakthrough such as 256GB solid-state drive, 90nm high-performance smart card chip, 82-inch 120Hz quad-HD-resolution TV panel, and a Mobile WiMax II (802.61m) solution.1 This also enables innovations like front-load washers with time, energy and wear-saving â€Å"bubble wash† technology and the industrys most compact colour laser printers. Following these success, Samsung plans to invest 7.9 trillion KRW in RD to support future development of tomorrows technology. 7 RD Structure and Priorities Table 2: Core business research areas at SAIT10 Research in Product Areas Descriptions Computer Science Drives long term differentiation of Samsung platforms(phones, TV) by combining Computer Science with Consumer Electronics Research involves building tangible artifacts like prototypes so that we can learn from the process of building them Current research: situation awareness, Intelligent Web Media and trusted platforms Situation awareness develops novel, optimal personalized services leading the next generation of personalized mobile technology Intelligent Web Media pioneers technologies such as new phenomenon in which all TV content is available on the Internet can be streamed or dowloaded directly to the TV Trusted platforms researches on strong protection of device firmware for network providers and users Wireless Connectivity Research in developing a wide range of cutting edge wireless techniques such as beam forming to initiate ubiqitous wireless connectivity with various data requirements up to multi-giga bits per second Digital Media Solution(DMS) Advanced Algorithm: engaged in research and development related to theories, algorithm, and application of image and video processing for Samsung Digital TVs Core Platform: Actively researching to provide Internet Protocol Television to provide internet and cable connectivity Future User Experience: develop user interface designs from conceptualization through prototyping to implementation Advanced Printing Solution Research in Software Architecture Technology enabling the efficient development of increasingly complex software Research areas in System Technology involves new features protoypes and etc Current and future research areas in Solution Software Technology are core research related to Web technologies and application of Web Services to printers Storage To develop quiet hard drives with highest storage capacity and lowest power consumption Organisation of RD Samsungs RD organisation run in SAIT consists of three layers: Samsungs technology competitiveness in core business areas identifies growth engines for the future and securing, and management of technology. The RD centres of each business focus on technology that is expected to deliver the long-term results. Division product development teams are responsible for marketing products due to hit markets in a short period of time. From the Figure 2, the organisation is shown to be a hybrid between centralised and decentralised RD. It is a simplified diagram of the organisation of Samsung RD involving SAIT and two of their centres in their global network of RD. Samsungs RD network consist of six centres in Korea and 18 centres in 9 different countries such as United States, United Kingdom, Russia, Israel, India, Japan and China. 11 These various RD centres and their distribution into research areas such as Dallas Telecom Laboratory that research on technologies and products for next-generation telecommunications systems. Innovation Strategy Firms Innovation Strategy Background and Strategy â€Å"By implementing this newly established RD plan, we can develop the technology that will drive Samsungs future.† -Hak-Soo Lee, vice-chairman of Samsung Electronics said.14 Samsung Electronics instituted many RD centres globally to enhance in-house product design. The first centre was established in Osaka, Japan, followed by another in Frankfurt, Germany to focus on products for the European markets.15 In the same year, Samsung Electronics established a research centre to address product planning needs in South-East Asian markets. In November 2000, Samsung Electronics targeted to transform itself into a â€Å"Digital -eCompany†, capable of leading in digital convergence. The company upgraded the development model from division-centric into portfolio-centri16. This aimed to multiple divisions and units to create integrated solutions for home networks, mobile networks, office networks and core-component business portfolios. With these initiatives, Samsung Electronics pursued four key areas: RD, design, brand marketing and corporate citizenship. Investment in Design and RD RD is an important innovation strategy at Samsung. RD and design centres developed technologies which is being used to produce products. Samsung Electronics employed more than 40000 engineers17 in its RD department, and 3,200 held PhDs. Samsung Electronics attributed its leading position in the industry to four main factors: creative people in the organization who could develop technologies; co-operation among business partners throughout the supply chain; the firms ability to explore and penetrate new markets; and the speed of innovation and product development18. Users-Centric Design Philosophy Samsung Electronics applied the design philosophy into its products and stressed that â€Å"design and creative strengths were at the heart of corporate competitiveness.†19 This reflected a concept of a balance between reason and feelings, from which Samsung Electronics developed a scale with â€Å"reason† on one end and â€Å"feeling† on the other to measure perfection of design. The products manufactured by Apple Computer Inc (â€Å"Apple†) occupied the â€Å"feeling† zone with an emphasis on simplicity of products, whereas Sony products tended toward the â€Å"reason† zone with lots of complex features.20 However, Samsung Electronics designers balanced â€Å"reason† and â€Å"feeling† by rationalizing the design of products using geometric and technological parameters and then enhancing the design such that products made an emotional connection with the user. Over 700 highly skilled designers in different design centres conducted various research projects in the fields of industrial design, graphic design, interaction design, human factors, lifestyle research; creative business-planning, visual brand strategy, materials exploration, colour theory and computer-aided design. Global Localization strategy Global Localization strategy is adopted, through which designers developed product design blueprints according to global design standards and themes, while remaining flexible enough to allow local design centres to accommodate specific market needs and cultural contexts.22 A simple example is explained by, Younghee Lee, vice-president of marketing, that beautiful design of mobile phones could be appreciated by a Parisian or Indian, but noted that the Indian user, who often lacked a reliable electricity supply, needed a longer-lasting battery than a Parisian.23 The Global Localization strategy helped Samsung Electronics establish itself as an innovative and first-class consumer electronics company. EXHIBIT 1: SAMSUNGS DESIGN PHILOSOPHY: BALANCE OF REASON AND FEELING Fast Follower To overcome the companys image as a producer of cheap products, Samsung Electronss product diversification differentiated the company from its key competitors, many of which were focused on single or smaller numbers of products. Apple, for example, specialised in portable music players and held a major share in the global market for these devices. Nokia and Motorola were best known for mobile phones, and Sony focused on consumer electronics. The market trends and technological, also the competitive circumstances impacts on its innovation strategy, which has a lots of reason to reveal that Samsung Electron is fast follower, although some brand-new design of products were launched. Protect its innovations Samsung Electronics strategy of combining product design, RD and brand management turned the firm into a leader in the consumer electronics market. Samsung Electronics operated six RD centres in South Korea and a total of 16 centres in eight different countries. These RD centres developed technologies that could be commercialised in the near future. The CTO developed proprietary technologies, managed the deployment of key technologies and guided the overall RD process within the organisation. This highly efficiency of organization system is not easily imitated by the rivals in a short period of time. Thus, it has enough evidence to believe that a large amount of RD spending combined with brand management as well as the effective organization system is able to protect its innovations. Patents and Achievement During seven years from 2001, Samsung Electronics received 19 awards at the International Design Excellence Awards (â€Å"IDEA†). In 2006, the company registered 17,377 patents worldwide, including patents aimed at fusion technology, nanotechnology and biotechnology24. In 2007, Samsung Electronics held a dominant worldwide market share25for LCDs and TVs. The company unparalleled edge and leadership in RD and design were underscored by awards for 32 of its products at the CES Innovations 2008 Awards. Challenges for the Future Competition in the consumer electronics market was fierce, as many global players entered the market with large product portfolios. Digital convergence invited more companies from related industries such as software, PC and network services to enter the market. Entry of such new players further intensified the competition. Competitors of Samsung Electronics such as LG, Nokia, Panasonic, Sony and some Chinese firms had started investing heavily in RD and product design. All major competitors adopted the concept of localizing their product design to suit target markets. The design advantage of Samsung Electronics started to diminish as product design strategies and processes became commoditized. Samsung Electronics had to devise strategies to defend not only its position in the market, but also its profitability in the competitive environment. Advancements in technology had shortened product lifecycles and product replacement had become a key driver for revenue growth. Samsung Electronics invested about 9% of net sales in RD of newer technologies, features and designs to offer newer products and attract customers. However, some of its competitors, including Apple, Sony and LG Electronics, had significantly lower RD expenditure per product. Firms such as Philips, Dell and Motorola were adopting outsourcing of product design to lower RD costs and shorten time-to-market. These brands were buying product blueprints and technology from contract manufacturers and independent design firms such as IDEO, Quanta Computer, Premier Imaging, HCL Technologies and Wipro Technologies. Companies took varying approaches to design outsourcing. For example, HP contributed key technology and design to its computers, whereas Dell preferred to adopt entire designs from its design partners. Motorola bought complete designs for its low-end mobile phones but kept tight control over the development of its high-end cell phones, such as the Razr. However, outsourcing of product design and RD raised serious concerns about intellectual property rights, product management, integrity and incubation of new competitors. For example, Motorola outsourced the design and manufacturing of its mobile phones to Taiwanese manufacturer BenQ. In 2004, BenQ started selling the mobile phones in the Chinese market under its own brand, which resulted in termination of its contract with Motorola. Considering the immediate urge to optimise RD costs and potential concerns associated with design outsourcing. References Samsung INC.

John Keats’ To Autumn and Percy Bysshe Shelley’s Ode to the West Wind E

John Keats’ To Autumn and Percy Bysshe Shelley’s Ode to the West Wind Even though both John Keats’s â€Å"To Autumn† and Percy Bysshe Shelley’s â€Å"Ode to the West Wind† are about the same season, they are very dissimilar. Keats’s poem concentrates on the creating power of autumn, and makes it seem a gentle season, while in Shelley’s poem death is a repeating image, and shows autumn’s destroying power. In â€Å"To Autumn†, Keats uses three stanzas of eleven lines each. The first seven lines of each stanza follow an ABABCDE rhyme-scheme. The remaining four lines of the first stanza follow a rhyme-scheme that is different from the other two stanzas. The first stanza has DCCE and the other two have CDDE. Some lines in the poem are indented, whereas others are not. Numbering the not indented lines 1, the lines with one extra spacing 2, and the lines with two extra spaces 3, the indenting of the lines follows exactly the same pattern as the rhyme-scheme, namely 1212-123-2113 for the first stanza, and 1212-123-1223 for the other stanzas. Shelley’s stanzas are composed of four interlinking triplets, following the principle of terza rima, and one couplet. The stanzas have ABA BCB CDC DED EE rhyme-scheme. Both poems have alliteration to emphasize the quality of the season: â€Å"Season of mists and mellow fruitfulness† shows the kind nature of Keats’s autumn, while â€Å"O wild West Wind, thou breath of Autumns being† shows the powerful character of Shelley’s autumn. The first stanza of â€Å"To Autumn† describes the way in which autumn is able to support life. On the one hand, its about ripeness as things grow older as the year is approaches its end, and helped by the â€Å"maturing sun† (l. 2), autumn has to â€Å"fill all fruits with ripeness to t... ...ally a form of hibernation. In â€Å"Ode to the West Wind†, death is a recurrent theme, but death is also mentioned in â€Å"To Autumn†. In Keats’s poem, however, it is clear that the creative power of autumn dominates the references to death. In â€Å"Ode to the West Wind†, the autumn is not only the brutal power it seemed to be at first: according to Shelley, autumn also has the ability to preserve life, by letting it die symbolically first. All in all, both poems show that autumn has a number of different facets, and it cannot be described by one or the other, but all. Works Cited: Keats, John. Ode to Autumn.

Electrical Power- Distribution System

Task 1: Describe the basic topology of the national grid network. The National Grid Network A national grid network is a network of cable that connects all the power stations in a country to transmit electricity to the consumers throughout the country. Electricity is in demand just about everywhere in the civilized world, and in Great Britain the network for supplying this electrical power is known commonly as the National Grid. The National Grid is an electric power transmission network which connects the substations and power stations.This is so that any electrical energy generated in Great Britain, can be utilized and help meet energy demands elsewhere. This grid system also includes interconnections that run under the sea to Northern Ireland HVDC Moyle, the Isle of Man and France HVDC Cross-Channel. The electrical energy generated for the National grid needs to be moved around all parts of the country to supply the demand. There are two methods available for the transmission and distribution of electric power and these are:   * Underground Insulated Cables Overhead Cables (Bare Conductors Suspended at a Safe Height Above Ground) The overhead lines are generally used for high-voltage long distance transmission, because the cost is lower than underground cables, especially at higher voltages. In British practice, high voltage transmission lines carry voltages ranging from 66kv to 132kv, and extra high voltage lines carry voltages from 220kv to 380kv. In all cases the power is transmitted in the form of three-phase alternating current at 50cycles/sec, and the cost of an overhead line depends largely on conductor size and voltage [Cheesman, 2007].Figure 1: General layout of electricity networks (Diagram taken from: http://en. wikipedia. org) Structure of distribution grids The structure or â€Å"topology† of a grid can vary considerably. The physical layout is often forced by what land is available and its geology. The logical topology can vary dependi ng on the constraints of budget, requirements for system reliability, and the load and generation characteristics. A typical topology of a grid is shown in figure 2 below. A A Figure 2: Schematic representation of a radial system (Diagram taken from: http://www. transanatolia. eu)Figure represent a classic electricity distribution grids-simple radial tree, sending power from a source (point A representing power generation or a substation) to delivery points (other points representing homes, businesses, or other sub networks). The cheapest and simplest topology for a distribution or transmission grid is a radial structure. This is a tree shape where power from a large supply radiates out into progressively lower voltage lines until the destination homes and businesses are reached. Most transmission grids require the reliability that more complex mesh networks provide.Other topologies used are looped systems and tied ring networks. National grids are composed of many smaller electrica l networks that are linked together into a larger network called a Wide Area Synchronous Grid, also known as an interconnection. A Wide Area Synchronous Grid allows all the independent electrical networks in a particular area to be connected by synchronizing the electrical frequency between them. United Kingdom interconnections are synchronized at 50Hz. |   | Task 2: describe the basic topology of the ring and radial feeder system. Radial Feeder SystemIn a radial configuration, lines branch out sequentially and power flows strictly in one direction, only one path is connected between each customer and the substations. The electrical power flows from the substation to the customer along a single path. If this path is interrupted, it will result in a complete loss of power to the customer. The loading of a distribution feeder is inherently unbalanced because of the large number of unequal single-phase loads that must be served. An additional imbalance is introduced by the non-equila teral conductor spacing of the three-phase overhead and underground line segments.Figure 3 below shows the radial feeder system. Figure 3: Radial distribution system Some of the advantages of this system include: minimum initial cost and simplicity of planning, design and operation. Disadvantages include: low reliability factor, distributor nearer to the feeding end is heavily loaded. Ring or Loop system: In a ring, any two points are usually connected by more than one path, meaning that some lines form loops within the system. This distribution system consists of two or more paths between the substations and the customers. It is selected to carry its normal load plus the load of the other half of the loop also.Therefore the size of the feeder conductor in a loop distribution system is the same throughout the loop. Figure 4 below shows the ring or loop feeder system. Figure 4: Loop distribution system Advantages of this system include: Less conductor material is required as each par t of the ring carries less current. Less voltage fluctuations.

Examples of where this would be used Solution:Distribution Subsystem The distribution system connects the distribution substations to the consumers’ service-entrance equipment. There are two types of distribution system: the primary and secondary distribution system. The Primary Distribution System The primary distribution lines range from 4 to 34. 5 kV and supply the load in a well-defined geographical area. The transmission system voltage is stepped-down to lower levels by distribution substation transformers. The primary distribution system is that portion of the power network between the distribution substation and the utilization transformers.The primary distribution system consists of circuits, referred to as primary or distribution feeders that originate at the secondary bus of the distribution substation. The distribution sub station is usually the delivery point of electric power in large industrial or commercial applications Primary distribution system voltages range from 2,400 V to 69,000 V. The distribution voltages in widest use are 12,470 V and 13,200 V, both three and four wire. Types of Primary Distribution System. There are two fundamental types of primary distribution systems; Radial and Network.Simply defined, a radial system has a single simultaneous path of power flow to the load. A network has more than one simultaneous path. Each of the two types of systems has a number of variations. Figure 6 illustrates four primary feeder arrangements showing tie, loop, radial and parallel feeders. There are other more complex systems, such as the primary network (interconnected substations with feeders forming a grid) and dual-service network (alternate feeder to each load). These systems, however, are simply variations of the two basic feeder arrangements.Some small industrial customers are served dir ectly by the primary feeders. Figure 6: four primary feeder arrangements. (Diagram taken from: www. navalfacilities. tpub. com) The secondary Distribution System The secondary distribution network reduces the voltage for utilization by commercial and residential consumers. Lines and cables not exceeding a few hundred feet in length deliver power to the individual consumers. The secondary distribution serves most of the customers at levels of 240/120 V, single-phase, three-wire; 208Y/120 V, three-phase, four-wire; or 480Y/277 V, three-phase, four-wire.The power for a typical home is derived from a transformer that reduces the primary feeder voltage to 240/120 V using a three wire line. Distribution systems utilize both overhead and underground conductors. The voltage levels for a particular secondary system are determined by the loads to be served. The utilization voltages are generally in the range of 120 to 600 V. In residential and rural areas the nominal supply is a 120/240 V, si ngle-phase, three-wire grounded system. If three-phase power is required in these areas, the systems are normally 208Y/120 V or less commonly 240/120 V.In commercial or industrial areas, where motor loads are predominant, the common three-phase system voltages are 208Y/120 V and 480Y/277 V. The preferred utilization voltage for industrial plants, however, is 480Y/277 V. Three-phase power and other 480 V loads are connected directly to the system at 480 V and fluorescent lighting is connected phase to neutral at 277 V. Small dry-type transformers, rated 480-208Y/120 or 480-120/240 V, are used to provide 120 V single-phase for convenience outlets and to provide 208 V single- and three-phase for small tools and other machinery.Types of Secondary distribution Systems. Various circuit arrangements are available for secondary power distribution. The basic circuits are: simple radial system, expanded radial system, primary selective system, primary loop system, secondary selective system, and secondary spot network.

Critical Essays on Keats poems Essays

Critical Essays on Keats poems Essays Critical Essays on Keats poems Paper Critical Essays on Keats poems Paper Essay Topic: Keats Poems and Letters Language is used effectively in both odes to create mood. In the opening stanza of Ode to a Nightingale, there is a sense of sluggishness, suggested by the heavy alliterative d, p and m sounds when Keats describes his heartache at hearing the song of the nightingale, ambivalently experiencing both joy and pain. Compared with the first half of the first stanza, the second half is full of light and sensual assonantal sounds such as beechen, green and ease. In this particular ode, there is a concentration on the senses and frequent use of synaethesia. In the first stanza, the visual can be said to evoke the aural and vice versa where the birds plot is described as melodious. In the second stanza, Keats manages to convey the taste of wine with reference to colour, song, dance and sensation, Tasting of Flora Dance, an Proveni al song, and sunburnt mirth. The fourth stanza combines sight with movement in there is not light, Save what from heaven is with the breezes blown, and in the fifth stanza there is emphasis put on the senses of touch and smell in soft incense. In the opening line of Ode on Grecian Urn, Keats makes use of a long drawn out i sound with his repetition in still unravished bride of quietness. Since Ode on a Grecian Urn is about a work of art, Keats draws attention to the fact that his ode is a work of art with the use of assonance, echoes and insistent sound patterns. His use of repetition in the second stanza, unheard echoes heard, sweeter sweet and pipes pipe, is effectively combined with the assonance of ears endeard and no tone. It is the frequent use of parallelism, constant personification of the urn, and the invocations and exclamations of this ode that highlights the specific language used for the reader. This ode uses what can be said to be poetic language as it draws attention to its artifice, to the fact that the poem has been consciously and artfully constructed. Both odes are written in ten-line stanzas, however, Ode to a Nightingale differs from Ode on a Grecian Urn in that it is metrically variable. It also differs from the other odes in that the rhyme scheme is the same in every stanza and consists of Keatss most basic rhyme scheme of all the odes, as it follows the scheme AB AB CDE CDE. Comparably, Ode on a Grecian Urn follows a similar structure to Ode on Melancholy and is made up of a two-part rhyme scheme. This rhyme scheme helps to create a sense of a two-part thematic structure where the first four lines of each stanza roughly outline the subject of the stanza, and the last six lines develop it. The final two lines of Ode on a Grecian Urn, in which the speaker imagines the urn speaking its message to mankind, Beauty is truth, truth beauty, have proved to be amongst the most difficult to interpret of Keatss work, along with the final lines of Ode to a Nightingale, where the speaker asks Was it a vision, or a waking dream? Do I wake or sleep? Keatss final question on the status of his experience in Ode to a Nightingale is problematic for a number of reasons. Whilst some critics have affirmed that the poem is about the inadequacy of the imagination, others believe there is a greater kind of ambivalence in Keatss attitude. It has been argued that Keats still suggests through his final question that such a vision or experience is possible, or at least, something he longs for. The last two lines of Ode on a Grecian Urn, Beauty is truth, truth beauty, is perplexing and has sparked much debate. However, it has been interpreted in several ways, mainly, in that it could be the speaker addressing the urn and it could also be the urn addressing mankind. It has been argued that if it is the speaker addressing the urn, then it would seem to indicate their awareness of the urns limitations, however, if it is the urn addressing mankind, it would appear that Keatss message is that beauty and truth are one and the same. There are significant differences between Ode to a Nightingale and Ode on a Grecian Urn, as in the latter, there is a sense of formality not experienced in Ode to a Nightingale. Most notably, there is no I and the focus is not so much on the mind as on the work of art, the urn itself. The suppression of Ode to a Nightingale is matched in Ode on a Grecian Urn, and in many ways, can be said to be companion poems. In the later poem, the speaker confronts a created art-object not subject to any of the limitations of time, whilst in Ode to a Nightingale, Keatss speaker achieves creative expression through the nightingales song which is spontaneous and without physical manifestation. In conclusion, though there are both evident similarities between the two odes, it is clear that their differences outnumber them. Whilst Ode on a Grecian Urn is much more formal, Ode to a Nightingale is arguably the more personal, if not the most personal out of Keatss odes. Perhaps it is the opening of the ode with the statement My heart aches that makes the ode appear subjective, whilst Ode on a Grecian Urn combines both subjective poetic expression but also objective historical expression. Although similar in format, the odes differ in their rhyme schemes and also it is the many paradoxes of Ode on a Grecian Urn that differentiate it from the Ode to a Nightingale. One of the many paradoxes found in this ode is that of the urn itself, as it is silent but is also said to be a historian that can communicate. Ultimately, one can appreciate that there are a variety of comparative and contrasting elements of the two odes, however individual each one may be.

Reagan and the 1983 Marines Barracks Massacre in Beirut

Reagan and the 1983 Marines Barracks Massacre in Beirut In 2002, the Presidential Oral History Program at the University of Virginia’s Miller Center of Public Affairs interviewed Caspar Weinberger about the six years (1981-1987) he spent as Ronald Reagan’s Secretary of Defense. Stephen Knott, the interviewer, asked him about the bombing of the U.S. Marines barracks in Beirut on Oct. 23, 1983, which killed 241 Marines. Here’s his answer: Weinberger: Well, that’s one of my saddest memories. I was not persuasive enough to persuade the President that the Marines were there on an impossible mission. They were very lightly armed. They were not permitted to take the high ground in front of them or the flanks on either side. They had no mission except to sit at the airport, which is just like sitting in a bull’s eye. Theoretically, their presence was supposed to support the idea of disengagement and ultimate peace. I said, â€Å"They’re in a position of extraordinary danger. They have no mission. They have no capability of carrying out a mission, and they’re terribly vulnerable.† It didn’t take any gift of prophecy or anything to see how vulnerable they were. When that horrible tragedy came, why, as I say, I took it very personally and still feel responsible in not having been persuasive enough to overcome the arguments that â€Å"Marines don’t cut and run,† and â€Å"We can’t leave because we’re there,† and all of that. I begged the President at least to pull them back and put them back on their transports as a more defensible position. That ultimately, of course, was done after the tragedy. Knott also asked Weinberger about â€Å"the impact that the tragedy had on President Reagan.† Weinberger: Well, it was very, very marked, there was no question about it. And it couldn’t have come at a worse time. We were planning that very weekend for the actions in Grenada to overcome the anarchy that was down there and the potential seizure of American students, and all the memories of the Iranian hostages. We had planned that for Monday morning, and this terrible event occurred on Saturday night. Yes, it had a very deep effect. We talked a few minutes ago about the strategic defense. One of the other things that had a tremendous effect on him was the necessity of playing these war games and rehearsing, in which we went over the role of the President. The standard scenario was that â€Å"the Soviets had launched a missile. You have eighteen minutes, Mr. President. What are we going to do?† He said, â€Å"Almost any target we attack will have huge collateral damage.† Collateral damage is the polite way of phrasing the number of innocent women and children who are killed because you’re engaging in a war, and it was up in the hundreds of thousands. That is one of the things, I think, that convinced him that we not only had to have a strategic defense, but we should offer to share it. That was another of the things that was quite unusual about our acquiring strategic defense, and which now seems largely forgotten. When we got it, we said he would share it with the world, so as to render all of these weapons useless. He insisted on that kind of proposal. And as it turned out, with this cold war ending and all, it didn’t become necessary. One thing that disappointed him most was the reaction of the academic and the so-called defense expert community to this proposal. They were horrified. They threw up their hands. It was worse than talking about evil empire. Here you were undermining the years and years of academic discipline that you shouldn’t have any defense. He said he simply did not want to trust the future of the world to philosophic assumptions. And all the evidence was that the Soviets were preparing for a nuclear war. They had these huge underground cities and underground communications. They were setting up environments in which they could live for a long time and keep their command and control communications capabilities. But people didn’t want to believe that and therefore didn’t believe it. Read the full interview at the Miller Center for Public Affairs.
