The Mosquito Coast Essay Example

The Mosquito Coast Essay Navigating the Global explores the challenges and complexities confronted by individuals embarking on a quest for a greater meaning in their lives. The concept of globalization is an ever growing understanding of the complexities and challenges of the late 20th to 21st century world where the increase in technology and communication has lead to the homogenization of cultural values. The concept of navigating through these complexities is referred to by critic T. Friedman as â€Å"An inevitable process of western civilization battling forces of primitivism and localism† Which can be seen in the 1981 novel The Mosquito Coast (TMC) by Paul Theroux and the 2007 film Into the wild directed by Sean Penn (ITW) demonstrates the consequences brought by failure to adopt the hybridity of the â€Å"glocal†. TMC depicts the geographical navigation from modern America to the most extreme form of â€Å"primitivism† Honduras as a journey of profound and moral significance away from American â€Å"the high prices, bad tempers, unpunished criminals†. In the opening chapters the audience is presented with Charlie’s father, Allie who criticizes the consumerist values upheld in America, through his tirades against American consumerist and materialist attitudes â€Å"Water ‘s as free as air. Those dinghbats are selling water! † illustrating his rejection of the mainstream Western consumer values. This results in Allie’s quest to escape the debauchery and despair of American society through the construction of a new â€Å"civilization† in Jeronimo.

ITW similarly portrays an individual’s quest through the navigation between the local and the global in search for a greater meaning in their lives from â€Å"history and oppression and law and irksome obligations† . ITW demonstrates the challenges faced by individuals’ differing perceptions of â€Å"freedom† by Christopher’s navigation from the US to Alaska presenting himself as an idealist similar to Allie â€Å"to kill the false being within, no longer to be poisoned by civilization†. The initial flashback to Chris’ rites of passage highlights the conflicting values imposed upon him by his parents and society† I see them standing at the formal gates of their colleges. The red tiles glinting like bent plates of blood behind his head. The dark imagery presented by the omniscient narrator along with the cinematography of mortar boards being thrown in the air depicts the inner conflict presents within individuals under the superficial mask of western expectations which results in the Chris’ escape â€Å"into the wild† The challenges faced by navigation of the global through a â€Å"woven world† can be seen in the figure of Allie Fox whe re manifestations within himself prove to have destructive consequences. Allie’s insistence of being the â€Å"last man† and feeling â€Å"like god† ironically, demonstrates Allie raising himself to a secular figure despite rejecting religion. This superbia is portrayed in the intertextual allusion to Frankstein, assuming God’s role at the ultimate creation â€Å"man is god† as Jeronimo becomes a personified embodiment of Allie’s dream. Allie’s creation of â€Å"Fat boy† an ominous allusion to nuclear destruction â€Å"plants scorched and stems blistered like flesh† highlighting the resultant destruction of â€Å"the forces of western civilization and localism†. Allie’s failure to adopt the local is contrasted by the success of The Acre an archetype of T. Friendman’s â€Å"glocalised society† which adopts the hybrid culture of communal acceptance and globalized values â€Å"spending money, arithmetic //we lived off the land† demonstrates the values from an individual’s navigation from their immediate environment becomes the fundamental of their own quest for meaning. Paralleled within TMC the destructive consequences of over indulgence in Western culture can be seen through the figures of Chris’ parents, Walt McCandless  and Billie McCandless  whose manifestations of academic success and wealth results in an unstable relationship †The divorce never happened,but the battles and the meetings never stopped. † The montage of celebration along with the non diegetic narration of the events highlights the superficiality of their connections as they indulge further into westernized values â€Å"the careerism and money seemed only to embolden their blindness. In contrast, the relationship between Gene Rosellini and  Jan Burres  demonstrates a stable relationship through adoption of the hybrid values of the local and the global, emphasised by the cross cutting of the McCandless â€Å"to find yourself at least once in the most ancient of human conditions with nothing to help you but your hands and your own head† Allie†™s failed quest for meaning in Honduras and his regression into â€Å"savagery† as he transforms into â€Å"a live scarecrow, the wild man† , is eflected in Charlie’s description of the river as he continuously attempts to move further upstream â€Å"The river bubbled and streamed with decay† which parallels Allie’s decent into lunacy with contradictory statements â€Å"We are the first family on earth// We are the last survivors†, highlighting Allie’s lost sense of direction which is symbolized by the truncated finger which he uses to navigate through the river â€Å"He waved his stump upward // every mile seemed like a mistake, because we were not free anymore†. ecomes an ironic motif as he transitions into a â€Å"scavenger† reinforcing the repeated imagery of cultures hovering above Allie foreshadowing his own death whilst navigating through the river due to his inability to adjust with the local â€Å"he was the savage not the Zambu† Like in TMC the river is a constant motif that parallels Chris’ journey towards Alaska serving as a means of direction in his quest for truth â€Å"rather than love, than money, than fame, than fairness†. The Rembrandt lighting of Chris’ face in his navigation through the river symbolises the realisation brought through by forced reflection â€Å"This fact suddenly re-defined Chris and me as bastard children† The corresponding relation between journeys and the river becomes evident as the Chris’ journey progresses through the chapters of his life. Similar to TMC the pathetic fallacy of the river demonstrates the inner journey Chris undergone as he reaches the end of the river and the film concludes with rhetorical questions â€Å"What if I were smiling and running into your arms? Would you see then what I see now? † demonstrating how Chris’ navigation through the river has resulted in a carthasis and thus ending his quest for meaning. Whilst Allie fails to successfully navigate the global ignoring his family and the knowledge of the local his son Charlie reveals a more empathetic, accepting and therefore a successful approach to the global experiences. Charlie’s navigation into maturity is highlighted as he uses his knowledge from both the local and the global as a distinct opportunity to save his family â€Å"but I wanted to go on // because there we were free†. Charlie’s development into maturity and psychological freedom is paralleled in his journey through the river highlighting an individual’s quest through the challenges and complexities can be overcome by adoption of the hybrid notions of the â€Å"glocal†

A right of privacy in Australi essays

A right of privacy in Australi essays Megan Richardsons article mainly focuses on the validity of a privacy right and whether an Australian right of privacy has emerged. However, there are three uncertainties that pertain to privacy: Ø How will a privacy right be protected? Ø Will the benefits of a privacy right be shared among commercial entities? Ø Is there a relationship between privacy and freedom of speech? The law of confidence can adequately protect privacy rights but there has been several cases that seem to reinforce the validity of such a right and this has haunt the courts continuously over many years. However, the protection of privacy interests has recently been explained and examined in greater detail due to the European Convention on Human Rights. In the case of Douglas Vs Hello! Ltd, the right to be let alone was brought up as the core of a privacy right based on a general idea of personal autonomy. The case serves as a landmark case to open the floodgates for the development of a right to privacy in the Australian jurisprudence. In the light of identifying personal autonomy as the basis of any privacy right, it is fundamental to determine why personal autonomy is important. There are two philosophical explanations brought up in the article, namely the Kantian idea and John Stuart Mills idea. The Kantian argument is clear and uncompromising. People are ends in themselves because they possess a rational will and this will manifest itself in decisions and actions and the respect due to the person requires autonomy. John Stuart Mills idea is more utilitarian. He feels that once people achieve a certain level of welfare and education, they flourish in an environment where free choice is possible. The importance of a person to have his own desires will produce positive changes. Both of these arguments are completely different but equally important in the development ...

Poetry and New Criticism Essay Example | Topics and Well Written Essays - 1250 words

Poetry and New Criticism - Essay Example Poetry and New Criticism For instance, ligh-T, s-KY, be-HIND, and Mount-AIN denote that the first syllable is unstressed while the second syllable is stressed in the words of the poem. The poem is also a tetrameter because the iambic rhythm repeats itself four times in each line of the poem. The poem is both narrative and descriptive. This is because it tells a story and, at the same time, explains the world that surrounded the subjects of the poem. The speaker in this poem explains the situation surrounding the subjects, just the way s/he perceived it. Threshing is rich of assonance. For instance, the - i - sound is repeated in the first stanza three times, that is, l-i-ght, beh-i-nd the mounta-i-n. The sound is also repeated in most of the lines of this poem. Alteration is also evident in the poem Threshing. For example, is like the sun’s shadow, the bread, if there’s bread, the leaves darken a little. To emphasize and stress on an issue or point, the poet has used consonance. For example, in the line, they lie in the shade, waiting, resting; the poet has repeated the consonant sound, -ng to emphasize on the activity that the subjects of the poem were engaged in. also, in the line, beyond the fields, the river’s soundless, motionless, the –ss consonant sound has been repeated to explain the status of environment surrounding the subjects of the poem. ... Also, the explanation of the river’s soundless, motionless scum mottling the surface, symbolizes the oppression. The poem is rich of imagery in that there are similes, metaphors and symbols have been used in the poem. For instance, the light behind the mountain has been liked to the sun’s shadow passing over the earth. Also, the cool environment under the trees has been liked to the flask of water that gets passed around. In the poem, the sun has been personified. In the line, the sun’s moving again, taking the men along, the sun has been given human attributes. For instance it said that the sun moves, and at the same time, it takes men along. This personification stresses emphasizes on the effect that the hot sun has on the subjects of the poem in terms of doing their work, and how it determines their fate because it marks movement in time. There is irony in the poem too. Men are sad to enjoy the hours when the sun is hot and their women are far way, but the wor k has not been done. It is therefore, ironical to enjoy a tie of the day when a lot of work still awaits to be done. Also, the poems states that the flask is put away, the bread, if there is bread, in one of its lines. It is ironical for people to lack bread, yet the main activity revolving in the poem is threshing of wheat. It is expected that with the activity of harvesting wheat, bread is supposed to be available in plenty. Nature has been used by the speaker of the poem to explain the surrounding the subjects of the poem. For instance, the hot weather characterized with the scorching sun emphasizes on the type of environment that the subjects of the poem dwell in, in that point of time. Nature also explains the oppression that the subjects of the poem face. The explanation

Utilitarianism, business ethics Essay Example | Topics and Well Written Essays - 1250 words

Utilitarianism, business ethics - Essay Example So every aspect must be examined to evaluate potential good and bad outcomes; if the goods outweigh the bads, then morally, the action can be deemed right. If there are more bad consequences predicted, then the opposite applies. As with all ethical and philosophical theories, there are more issues to be considered, nothing is quite so simple. Different forms of utilitarianism have been described over the centuries, like Bentham's pain - pleasure as bad and good consequences. (Ethics, 8), but all seemed to attempt to measure and define what 'utility' actually means. If utilitarians consider morality to be all about consequences, then how are consequences measured, which calls into question how utility can be measured and how much of it is the ideal level to aim for Hinman states: "utilitarians must answer the question of whom these are consequences for" (137). This question is highly relevant when applied to using utilitarian ethics in business, and in particular, within the context o f the Ford Pinto case, to be discussed later. There are many different versions of the theory, all trying to define what consequences are applied to and how they may be applied. One version, rule-utilitarianism, considers that a rule or code of behaviour is morally right if, by its application, the consequences are more favourable that unfavourable to everyone. The actions driven by the rule would result in benefits, or goods for all of society. One example might be a Council's Urban Regeneration Programme, funded by Council Tax. The rule is that everyone must pay, and in doing so, produce an outcome that creates a better environment for the majority living in the urban area. The flaw is that those in the suburbs, who contribute the greatest amount, will not receive as much favourable consequences, on the premise that they already have plenty of utilities. So simply following a rule would not always be equally favourable. On the other hand, act-utilitarianism, the most common form used in many circumstances, looks at the consequences of every case individually and works out the benefits before taking a morally right action. Leggett (13) in commenting on Ford's use of utilitarian ethics, says: "The utilitarian approach evaluates each action separately and the consequences that arise from it. This analysis would include any 'harms' or 'benefits' incurred by any people involved in the case." Business Ethics: In applying utilitarian principles to business ethics, the cost-benefit analysis is most often used - it is a good decision making tool. Companies will attempt to work out how much something is going to cost them before taking action that should, ideally, result in consequences favourable to everyone. That would mean the company could make a profit, while the consumer benefited from their product. Hopefully, products are fit for purpose, safe, and give value for money. No business would attempt a project without evaluation of all relevant factors first, as well as taking other issues or risks into account that might jeopardise success. Ethical business practice, using

Abuse of Legal & Ilegal drugs Coursework Example | Topics and Well Written Essays - 500 words - 1

Abuse of Legal & Ilegal drugs - Coursework Example It is a reflection of the importance attached to the prevention of drug abuse by the authorities (Columbia Univ., New York, NY. National Center on Addiction and Substance Abuse. No Place To Hide: Substance Abuse in Mid-Size Cities and Rural America, 2001). This article contains the results of a drug abuse survey, which had been conducted by the Partnership for a Drug Free America. It deals with the effect that communication between parents and their children, has on the abuse of prescription drugs. It is an authoritative work on the effect of communication with one’s children, in drastically reducing addiction to drugs (Fathers need to talk more to kids about drugs 6/27/2005, Vol. 17 Issue 25, June, 2005). In order to take on the menace of teenage drug abuse, the Gallup High School in New Mexico, adopted a number of novel and innovative measures. Some of these are imparting knowledge of the problems resulting from abuse and the explicit and implicit effects of such abuse. A number of contributing factors like peer pressure, domestic environment and addiction were considered. The author, as the substance counselor of that school, has thoroughly studied the problem and has adopted an addict centered approach to the problem (Mulroy, 2007). Office of National Drug Control Policy, Washington, DC. (February, 2007). Teens and Prescription Drugs: An Analysis of Recent Trends on the Emerging Drug Threat. 1. Retrieved February 7, 2008, from ECSCO HOST Research Databases. (Document ID: ED495769). There is a proclivity, amongst teenagers, towards prescription drugs, in order to become euphoric. The use of prescription drugs is second to only that of the use of marijuana. Their use is enhanced by the common fallacy that they can be imbibed safely. OxyContin and Vicodin are the favorites of the teenage drug addict. Moreover, girls abuse prescription drugs more than boys. The

Applications Of Laser In Engineering English Language Essay

Applications Of Laser In Engineering English Language Essay Introduction: Laser has many applications in different fields especially in engineering. It is one of the most important inventions in the last century. Laser is used widely in the engineering field providing facilities while applying many engineering processes. Its applications also helped in the development of engineering. . Laser is an important instrument in engineering; that has been used widely by engineers in many aspects for its wide purpose and usefulness laser is a solution looking for a problem. This report aims to analyze the applications of laser and discuss the effect of laser on the product produced by this applications. This report gives detailed information about different engineering applications of laser. History of Laser: The first idea of using rays of light to help in exiting and changing the appearance of atoms discovered by Albert Einstein in 1917. He said that it would be possible to make an atom release light or make any unusual actions using rays by definite frequency. But he was not the one who invented laser itself; he just opened the way to other scientists to work on it. Schawlow and Townes are the two persons who first applied the idea of laser but they failed in their first experiment. In 1960 they succeeded to generate the first laser beam using a type of ruby. What Does LASER means? LASER stands for Light Amplification by the Stimulated Emission of Radiation Laser is a device that emits electromagnetic waves in the form of a special type of light. It spreads as narrow coherent beams that can be turned into one using lenses. Laser has many uses in different fields so that people needed that effective invention. Laser simply consists of a narrow light beam that is produced by a process called Stimulation of atoms. This process is held by using an amplified light beam of specific frequency and intensity. That light beam is used to stimulate the atom. Stimulation of the atom means that we give it an extra amount of energy that makes in excited. That excitation makes the outer most electrons move to a higher level. Then they need to get rid of this extra energy to be back to its original and normal state, so it emits that extra energy in the form of a light beam. That light beam is laser. Thats how laser is produced. Laser solved many problems that faced engineers before inventing it. It facilitates many processes and operations for engineers. It also helps them find some information they need. As an example; before inventing laser; cutting and welding operations were very difficult. It was a problem to cut a metal, as you had to heat it up to a very high temperature then you modify its shape. Laser solved this problem and made that operation become very easy and fast. As another example; before inventing laser there were no wireless connections or laser radars. Laser also made the communication processes very fast and widely used. It made solutions for many problems that irritated engineers and people. Laser opened many knowledge and technology ways that would be impossible without it. After inventing Laser it became impossible to imagine our life without it. It became the key of many engineering operations that it will not be carried out without laser. Accuracy is one of its most important advantages that remove any doubts around it. It is expected that laser will be developed more and more in the future to provide engineers by other facilities. It can also be a reason for inventing other technologies. Again, Laser can be our gate to other inventions that could make our life easier and more comfortable. Laser Beam Welding Laser Beam Welding LBW is a contemporary welding technique used to join multiple pieces of metal using a laser. The beam provides a concentrated heat input, allowing for narrow, deep welds at high rates. This process is frequently used in many applications and develops to new industries. Laser beam welding has been extensively used in the automotive, aerospace, electronic, and heavy manufacturing industries to join a variety of materials. In the automotive industry, high-power lasers are used to weld many components such as transmissions, mufflers, catalytic converters, exhaust systems, and tailor-welded blanks.(Wikkipedia.com) Because of Laser welding advantages such as deep welding and reduced heat inputs. Profound Manufacturers sought to automate the welding process caused the expansion of the laser beam welding process to include computers sophisticated technology to increase the product quality and more accurate control of the welding process. From More than 20 years ago, when laser welding was in its early stages it was used primarily for bizarre applications where no other welding process would be suitable. Nowadays, laser welding is an imperative part of the metal toil industry. Laser beam welding has high power density (on the order of 1  Megawatt/cm ²(MW)) resulting in small heat-affected zones and high heating and cooling rates How it works: The Focal point is aimed on the work piece surface that weld is needed. At the surface of the work piece, the enormous concentration of light energy transformed into thermal energy. The surface of the work piece starts melting and steps forward through it by surface conductance. For welding process, the beam energy been maintained below the vaporization temperature of the material. In Fig. 1 the laser beam is directed on the work piece. Figure 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ1 laser beam aimed on the work piece Image courtesy of NorteastLaser.com To the point that the laser beam contacts the work piece, all the components that direct it are transparent, refractive or reflective, absorbing only small amounts of energy from the ultraviolet light (www.accuparts.com). When the pulse of laser energy is focused into a small spot at the surface of the work piece, the energy density becomes enormous. The light is engrossed by the work piece, causing a keyhole effect as the focused beam drills into, vaporizes and melts some of the metal (www.accuparts.com).. As described in fig. 2. Figure 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ2 laser beam welding process Image courtesy of NorteastLaser.com In fig. 3 as the pulse ends, the liquefied metal around the keyhole flows back in, solidifying and creating a small spot weld, moving the work piece or the laser emitter along the surface of the work piece creates a series or spot-weld called a seam. Figure 1à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ3 the keyhole effect by laser beam Image courtesy of NorteastLaser.com Equipment The two types of lasers commonly used in are solid-state lasers and gas lasers (especially carbon dioxide lasers and Nd:YAG lasers). The first type uses one of several solid media, including synthetic ruby and chromium in aluminum oxide, neodymium in glass (Nd:glass), and the most common type, crystal composed of yttrium aluminum garnet doped with neodymium (Nd:YAG). Gas lasers use mixtures of gases like helium, nitrogen, and carbon dioxide (CO2 laser) as a medium. (wikkipedia.com) Advantages of applying Laser Welding One of the major advantages that laser welding is the low amount of heat that is used during the welding process. The process repeats the laser beam to allow for the cooling of the spot weld, resulting in a very small heat affected zone, which makes the welding process use less energy, and makes laser-welding ideal for thin sections or products that require welding near electronics faultless. In conclusion, I would say that laser beam welding process when united with robotics and computer-controlled beam movements or work piece movements make laser welding systems offer a supreme flexibility to perform a variety of operations. 3D laser scanning 3D Laser Scanning is a type of reverse engineering. Reverse engineering helps in knowing more information about any object, software, device or a system. It mainly works by analyzing any part of that object and taking it apart to know everything about it using laser. It returns that object to its origins and know how to make a copy of it without destroying the main object or modifying it. That type of engineering can be used in many fields and it can be applied on anything as it is a high quality technology. That technology depends mainly on laser and its various types. Reverse engineering analyzes objects to examine how it works or how it has been done. It also can be used to know the dimensions of a place or an object. It is mostly used on objects that it documentations are lost. 3D Laser Scanning is used to measure the dimensions of a place or a part of a place by converting physical objects or parts into data to be read on a CAD program. That measurement is done by a coordinate measuring machine that estimates accurately what are the dimensions of that part. After measuring; the CAD program draws 3D images of that part. That method helps in knowing the dimensions of the object accurately without errors or assumptions. The 3D images produced by that method are called virtual reality. Those accurate 3D images need a very large amount of data as it measures fine details of the object. Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ4 3D image drawn using 3D laser scanning The amazing thing about 3D laser scanning is that it is supposed to take a long time to measure the fine details of an object accurately then reverse it into data that can be read by CAD programs. But actually that process takes seconds. It saves a lot of time which the person can spend to draw that object or try to measure its dimensions by any traditional method. That shows how laser helped in saving much time for engineers. Laser captures every single detail in the object in a tremendously fast and accurate way. It is impossible for human to reach that level of accuracy even if he spends hours or days trying to reach it. 3D laser scanning is applied in 3D scanners, coordinate measuring machines and 3D digitizers. As we said; it is the fastest and most accurate measuring method that can analyze objects to know how it works or to know its dimensions. Also it saves effort and money. This application is such an amazing application of laser in engineering fields. People call it hard work that looks like magic. Communication systems: A communication system is designed to transmit and receive information using light beams like fibers. Laser works as a light beams which has enormous potential for data transmission with very high data rates. Laser communications systems are wireless connections throughout the atmosphere. Before using laser in communication, the Greeks used fire and smoke to transmit information, by the evolution of the technology, optical fibers and radio waves are used for the communication of information over distance. Nowadays, lasers are used in optic fibers communications, fibers optics is a medium for carrying information from one place to another in the form of light. Unlike the copper transmission lines, fiber optics is not electrical in nature. Communication systems are based on optical fiber because of its advantage over metallic transmission lines. Fiber optics is used increasingly in data and telecommunications. Optical data transmission is increasingly used in various areas, such as telephone, internet traffic, cable TV. In Japan, many internet connections are already delivered to home with optical fibers. How does laser work in communication system? Figure 3à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ5 laser communication process Advantage of laser in communication system: Lasers have some special characteristic such as good directivity, polarization, monochromatic, coherent. The approach of optical fiber communications has advantages compared with systems based on electrical cables, the most important are: The losses for light propagation in fibers are very small because there is no fraction. The capacity of fibers for data transmission is huge and its also fast in the storage of data. Compared with electrical cables, fiber optic cables are very light weight, so the cost is very low. Due to the huge transmission rate of data, the cost compared by the rate of transmission is low. In fibers optic cables, the problems that arise with electrical cables such as ground loops or electromagnetic interference are eliminated. Figure 3à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ6 There are several significant advantages for communication system that operate with fiber optics than systems which use radio frequency: Laser communication provides much higher data transmission rate compared to radio frequency. Small dimension light weight of components. Lower power. Application of laser in space communication: Lasers used in free space laser communication systems, its one of the most important application of laser in communication either semi-conductor laser diodes, solid state lasers and fibers amplifiers lasers. Free space optical communication is the transmission of data over long distance, e.g. between: Planets. Earth and satellites. Spacecraft and Earth based station. Figure 3à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ7 laser communication between satellites Figure 3à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ8 There are some advantages of the use of laser in space optical communication such as : high power, large rate of data transmission, small size and light weight, but one of the main disadvantage of using laser as a link in space communication is the interconnection only between points that have direct line of sight. The application of laser communication is discussed for a global communication system and an inter-satellites link, because laser can be directed in fibers over very long distances with very low losses and avoid atmospheric influences. CD DVD Introduction: Laser plays an important role in our life; it has a lot of applications in a lot of fields. It is used in many fields like medical, scientific, and industrial. In this part Ill talk about some industrial uses of the laser like CD DVD Holography. Figure 4à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ9 cdWe all know the importance of CDs and DVDs in our life. We use it in saving data, music albums, and videos. CD means Compact Disk optical media that can store data, and DVD means Digital Video Disk, and its also optical media to store data but with larger storage size, and much greater capacities. Figure 4à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ10cd romSo I can say that we have two types of disks and three types of drivers; for the disks we have CD and DVD, the difference between them would be in the storage size. For the drivers we have CD-ROM, CD-RW, and DVD-RW. The difference between the CD-ROM and CD-RW that the CD-RW has the ability to read and write data on the CD, but CD-ROM can only read from the CD. So its like read only memory; DVD drive can read and write on both CD and DVD disks, and has a larger storage memory than CD, so DVDs is more useful and better than CDs. Figure 4à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ11 Reading from CD How CD and DVD drivers work? Computer takes the data from the user through keyboard, microphone, or any input device and converts it to zeros and ones. The idea is to store the data from the computer to the disks write on the disk using a powerful laser beam that makes holes or bumps on the disk which represents zeros and grooves that represents ones, so we can write what we want on the disk. CD and DVD the both use the same method to record data on. Figure 4à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ12Data saved on CD To read from disk, the drive uses beam of laser that reflects back to a sensor in the drive if it hits a groove or one, but it hits a bump or zero the beam reflects with an angel and doesnt hit the sensor; through this operation the drive can read data from the disk. Differences between CDs and DVDs: We all already know that CDs have a storage size 700 Mega Byte, and DVDs have storage size start from 4 Giga Byte. Also DVDs could have multiple layers so its storage size could reach 17 Giga Byte, but CDs only have one layer. So we can say that CDs are much cheaper than DVDs, but DVDs are more useful, and have much greater storage size. So CDs are still preferred in publishing music albums, and DVDs are preferred in publishing movies. Also we can say that there is a big difference between the CD and DVD drivers. We would find that the DVD drivers use a thinner beam of laser than the laser beam of CD drive so it could make smaller grooves and bumps than CD drives, so it could write on both CDs and DVDs, but CD driver could only write on CDs and cant write or read DVDs. Figure 4à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ13 cd writing process Figure 4à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ14 Cd writing process Applications of laser in communications: Laser radar (LADAR) or (LIDAR): Laser radar (LADAR) or (LIDAR) (Light Detection and Ranging) is similar to millimetre radar but it uses laser beams to find its target. The (LADAR) processor looks for familiar patterns in the scenes. The processor continuously compares the scenes taken with the 3D files stored in the radar memory. It can scan large areas with very high precision and its ability to build a detailed picture of the area. The (LADAR) sensor can look at the target from different angles. Laser radar seeker can detect objects features with very high definition up to 15 cm resolution from about 1000 meters. After the radar identifies the object it takes a 3D picture. Laser diode: Laser diode is a diode where the active medium is a semiconductor similar to light emitting diode; this diode is used to produce n-p-n or p-n-p transistors that are used widely in electronic systems, these diodes are sometimes called injection laser diodes to distinguish between optically diodes. A laser diode is formed by doping a very thin crystal wafer on its upper surface using laser beam to produce a n type region and a p type region results in a p-n junction which is called a diode Laser fibre: A laser fibre is a glass or a plastic fibre that carries light through it. These fibres are used widely in fibre-optic communications which permits transmission over long distances and at higher bandwidth than other forms of communications. Fibres are used instead of metal wires because signals travel across them with less loss and they are also immune to electromagnetic interference. Fibresare also used for illumination and sensors. Laser microphone: The laser microphone is a device that uses a laser beam to detect sound vibrations in distant objects. The device takes vibrations as a pressure waves created by objects in the room (like person or an object), the laser beam is directed into the room from a window that hits the object then it returns back to the receiver that converts it to an audio signal. The minute differences in the distance travelled by the light as it reflects from the vibrating objects (are detected interferometrically is a technique used for diagnosing two or more waves by studying the pattern of interference created by their superpositions). A new type of laser microphones that uses laser and a smoke or vapour to detect the vibration waves in the air. Applications of laser in computer: Laser barcode scanner: The laser beam bounces off a rotating mirror and scans the code, sending a modulated beam to a light detector and then to a computer which has the product information stored. Semiconductor lasers can also be used for this purpose, laser barcode scanners are the most common used barcode scanners, laser barcode scanner doesnt need to be in contact with the barcode to read it, it can read barcode 6-24 inches away from it. Laser printer: A laser printer is a type of computer printers that rapidly produces high quality text and graphics on a plain paper. It is a computer printer that uses laser beam to produce an image an on a rotating drum before transferring it to the paper. As with digital photocopiers and multifunction printers, laser printers employ a xerographic printing process but differ from analogue photocopiers in that the image is produced by the direct scanning of laser beam across the printer photoreceptor. A laser beam projects an image of the page to be printed onto an electrically charged rotating drum coated with selenium. Photoconductivity removes charge from area exposed to light, the drum then prints the image on a paper by direct contact and heat. Laser printers have many advantages than other printers like the speed of laser printer can vary widely, it can print 12000 pages in one hour.

First Chapter of Lord of the Flies Essay

The first chapter of Lord Of the Flies introduces Ralph at the very start roaming the jungle. This contributes to the mysteriousness of the literature. Not telling you where he came from or why he is there makes the story enticing and entertaining. The author was adding to the rising action. The setting in the very beginning was the Jungle. After Ralph walks for a small amount of time, a voice calls out to him asking for help, and to wait up. This is another way to make the story seem mysterious. He learns it is a boy with the nickname Piggy. Piggy joins Ralph and they walk to a lagoon. There they find a conch shell and Ralph blows through the conch which then calls on an large amount of boys. The author most likely added this to make another curve to the story. To show how much about the place Ralph and Piggy didn’t know. When the large group arrived, a boy named Jack Merridew asked where the ship was, and where an adult was. This showed how ignorant Ralph was because he had no clue what the conch sound meant to the people that were already there. Then Johnny and the twins Sam and Eric arrived along with many other younger and older boys. They talk as if they all have an education which shows they were also put here, not born here. The dialog seems modern and easily understandable, which shows that the setting is more recent than historical. Ralph is voted leader and commands that they explore to see if where they are is an island. Accompanying Ralph is Simon and Jack. Piggy is left behind to log names, which upsets him. The reason the author wrote about the exploration is to show the others don’t know where they are either. Throughout the venture, the boys are faced with a series of things in their path. They push a boulder off a cliff. The author most likely added this to show they weren’t hopelessly stranded on the island. The end of the chapter the boys realized they were hungry. They searched for food and found a pig, in the grips of the ‘creepers’. The author didn’t explain what the creepers were and it made it much more elusive. Jack fails to stab the pig quick enough and he made up excuses as to why he couldn’t. It shows that he isn’t nearly as tough as he lead on to be. He slams his knife into the tree to show he is in fact still the alpha male. The first chapter left many unanswered questions.

How to Improve Our Government Essay

People every day make mistakes, and find flaws in their everyday tasks. No one person in this country can consider his, or herself, perfect. Knowledgeable people do exist in this world though, and our government strives to find and elect these representatives. These representatives then make decisions that affect our country in ways some might find positive, though others perceive as negative. Representatives could make decisions that would only impact our government in a negative way. Our government has its flaws, along with the people running it. I can think of several ways to help to improve the government and its efficiency. A decrease in government funding for our National Defense would increase funding in other important areas. People across our nation need jobs, and are struggling to find a source of income. If we used some of the funding that we attribute to our Nation Defense, then this money might benefit in the use of creating new jobs and opportunities for people. Not only would we have money to provide jobs, but this funding could be used to help create and search for new information in the field of Cancer Research. The government funds provide people that lack occupations and have no source of income, with a reliable way of obtaining money for themselves to provide for his or her, and/or his or her family. These welfare recipients may draw unemployment after applying and meeting the requirements need to obtain this welfare money. These requirements may not be strict enough, which would lead to the allowance of the unemployed to gather money while being lazy in the process. Due to the lack of work ethic found in people, drug use may attribute to this laziness. A requirement may need to be added in order for the recipients to pass a drug test (a test for multiple drugs) in order to draw unemployment, in return saving the wasted money the government provides to the unworthy. The government could invest much of their funding in renewable energy sources. The post installation outcome of these windmills, energy providing dams, etc. would help save money later on in the future. With these funds being provided to help â€Å"Go Green†, the earth itself would take a drastic increase in cleanliness. The government then might avoid conflicts  with foreign nations in the search for the fossil fuels, of which we currently use as energy. Doing this might then allow us to pull our troops out of these foreign nations, saving lives and money provided for the troops. The government has a reliable system that has gotten our country out of some troubled times, and may be one of the most united governments the world has seen. As previously stated though, nothing and no single person is perfect. With these little changes in the way the government goes about, it may impact funding, our unity, and occupations for the people of the United States, allowing people to live and prosper, with freedom and peace throughout.

Alarm Fatigue in Nursing Essay Sample

Alarm Fatigue in Nursing Essay Sample Alarm Fatigue in Nursing Essay Example Alarm Fatigue in Nursing Essay Example It is becoming increasingly difficult to ignore the fact that a sphere of healthcare and nursing requires a significant attentiveness regarding patients and related operations. Still, human errors cannot be fully avoided. Hence, such phenomenon as alarm fatigue may occur in many fields of human activity, especially in the sphere of healthcare. Needless to say, reaction on various alarming signals is an average activity for healthcare workers, but there is the most threatening implication. In fact, constant and frequent reaction on alarms makes a human-being less sensitive to them. Thus, such problem requires an adequate addressing. Alarm fatigue is caused by a wide range of factors so that there is no distinct methodology concerning the issue. That is why a middle range theory is suggested for methodological basis for dealing with alarm fatigue as long as it integrates theoretical knowledge and empirical evidence. Taking such point into account, the following paper focuses on the dis cussion of middle range theory appliance to a case of alarm fatigue in nursing. The Dangers of Alarm Fatigue To speak about the problem, it should be admitted that it is a so-called phenomenon named alarm fatigue. The phenomenon can be described as a loss of sensitivity to alarms, threats and any other warning signals due to a frequent and regular perception of them. Contextualizing the problem in terms of nursing, it is to be said that the problem is mainly connected to the healthcare personnel. Nurses and other staff become adjusted to their workplace environment to the extent that they start paying less attention to changes in patients’ state, their complaints, data demonstrated by measurements and medical equipment, special requirements to the patients’ condition, etc. It can be explained by the fact that healthcare staff members face such aspects on a day-to-day basis. Psychologically, such irritators become less influential, since the personnel members have acquired them as usual events in their daily routines. As a result, a loss of sensitivity may lead to worsening of the patients’ state. Moreover, it will be difficult to restore the same sensitivity again because it will be a conscious focus on a certain aspect. Consequently, the problem has to be addressed and it is suggested to apply a middle range theory to it. It is necessary to be explicit about what is meant by the term of middle range theory. Current theory is based on the integration of theoretical knowledge and empirical evidence so that a related activity addresses real cause of the problem. It is not tied to any certain framework but creates orienting statements, which are utilized as the basis for the further empirical activity. Applying middle range theory to the case means its implementation in a form of theory of meaning. Such nursing theory suggests that a patient has to understand meaning of his or her treatment in order to feel motivated and positive regarding recovery (Liehr Smith, 2014). The case of alarm fatigue, however, presupposes appliance of the theory directly to a nurse or any other representative of healthcare personnel. Such individual has to be careful about patients’ state, their complaints and all data related to the patients in order to react immediately in case any emergency occurs. The conviction rel ates to the professional duties of the individual. In case he or she fails, a threat to lose the job can emerge. Employment is commonly associated with personal well-being so that the individual will be as careful as possible. One may argue that it is cynical to address alarm fatigue from that point of view, but consideration of personal well-being is one of the primary human instincts, to which the theory of meaning can be applied. The choice of middle range theory can be explained by the fact that it addresses not only a distinct sphere of human activity by considers the related fields and disciplines. The theory has its origin in sociology. Robert K. Merton was attempting to integrate social theories of conflict and functionalism. As a result, middle range theory places a subject at medium range towards every single aspect of human activity and knowledge. In other words, a problem is focused on consideration of the entire variety of perspectives. Therefore, such approach allows healthcare personnel to base any professional theories with consideration of non-healthcare factors. In such way, the theory addresses practice and is applicable to the entire discipline of healthcare and nursing, since every single case can be regarded as unique. What is more, alarm fatigue is a common problem among healthcare staff members so that appliance of middle range theory can contribute much to the nursing practice, especiall y in regard to the fact that nursing and social theories are mutually connected. With regard to the previous evidence of appliance the theory to nursing, it was generally applied in terms of meaning theory. However, it was directed towards patients in cases of loss intention, motivation and carefulness concerning the treatment. As a consequence, absence of communication with nurses and other staff members could be observed in such sort of cases. It led to the complications concerning treatment and worsening of the patients’ state. Thus, middle range theory suggested strategies of conviction a particular patient to cooperate with healthcare staff. The theory considered personalities of the patients as long as the majority of deviations from treatment course are caused by traits of character or psychological condition of a patient. Middle range theory helped create basis for motivation and cooperation of a patient. Further, his or her participation in personal treatment was highly appreciated by healthcare staff. It is a crucial point, since a patient should feel his or her contribution regarding the treatment. As long as middle range theory is applied to the exact representative of healthcare personnel, it should be admitted that such individual motivated himself by the previously outlined sequence of statements regarding professional obligation and consideration of personal well-being via obtaining a job position at a healthcare organization. As a result, the individual paid attention to all evidences, which can be related to his patients. In such way, a possibility of developing alarm fatigue was definitely low. It can be explained by the fact that the individual kept all evidences and data recorded. Moreover, statistical data was compared to previous recordings. In consequence, potential development of tendencies was also forecasted (Liehr Smith, 2014). Conversely, the addressing of alarm fatigue does not mean excessive anxiety concerning missing signals of threat. It is important not to demonstrate any anxiety in presence of a patient in order to avoid psychological traumas.

Alarm fatigue occurs in healthcare quite often so that it requires an appropriate addressing. In consequence, middle range theory has been suggested in terms of nursing theory of meaning. Such complex has been suggested for motivation of healthcare staff representative in order to be careful regarding the patients’ state, complaints and any other related data. The motivation has been formulated on the basis of professional duty obligations and considerations of personal well-being.

Use Foucault's theory of the disciplinary society to analyse three Essay

Use Foucault's theory of the disciplinary society to analyse three examples of body discipline - Essay Example Foucault considers this physicality -such as pain, hunger, sorrow, joy, etc- a subject of politics and power. The idea, that body is an object that can be subjugated, threatened and tortured by the external forces and power, gives birth to the concept that body’s fear of torture and pain can be manipulated to grow body disciplines in accordance with the social disciplines. In fact, for Foucault, ‘body’ has always been in the center of the attention of any forms of power or authority because body is easily accessible and manageable by controlling its various organic needs, as referring to Foucault’s obsession with the physicality of human being, Peter Erlandson says, â€Å"Foucault stresses that as well as studying the body as a seat of ‘needs and appetites’ and other ‘biological events’ in the social sciences, the politics of the body also needs to be studied† (662-3). This paper will explore how Foucault’s social dis ciplinary theory explains the body disciplines. According to Foucault, discipline as one of the social constructs developed as a response to the increasing demand of the reformists to view the public or social body in power of the state. This concept of â€Å"the power of the public body† necessarily viewed an individual as a body that needs to be disciplined in accordance with the disciplines followed by the collective social body. But Foucault notes that the social body itself is a group of individual bodies that have internalized a set of acknowledged rules and regulations through a number of social disciplinary organizations. According to Holligan, the social institutions functions as â€Å"regimes whose purpose and success is predicated upon making bodies obedient and practically valuable within a particular social formation† (138). An individual that violates the social disciplines is viewed as a physical power or body that lacks the

Pardoner giving his tricks of the trade in most of his works, for example, he explains to the pilgrims the major cause of most evils. This expression forms the key theme that he uses most of the time while preaching so as to understand better and loosen the purse strings of most of his audiences. On arrival to town, Pardoner demonstrates some of the relics and their curative traits some of which appeared to be fake though he does not appear to be caring a bit.
