Design for an information system Research Paper

Design for an information system - Research Paper Example Broadly, an information system in the context of an organization is the harmonization of user needs, standard operation procedures, data, software, and hardware to process and manage digitized information. The need to computerise traditional health care information systems is overwhelming. Health care systems need pooling of patient records, better and more easily accessible electronic health records, patient scheduling and billing services for patients. The need for robust and highly functional computerised systems for an urgent care facility are especially critical, and system developers have already made considerable inroads in implementing the use of computerise systems for the management of the facilities. System development depends on a number of methodologies whose overarching mandate is to ensure the entire process of development to implementation goes smoothly, achieves the initial objectives and gives a desirable benefits-to-costs match. In this study, we look at the comput erization at SFO Medical Clinic, a Californian clinic that among other services offers urgent care to its broad range of patients. The goal of this paper is to identify and document a fully functional information system for a small company.

Information systems have a far-reaching impact, with the principal aim to improve or replace existing systems. Therefore, the need to emphasize functionality over design is the supreme purpose of developing an information system. The goal of making highly functional and more efficien t is self-evidenced in the information system methodologies and the varying approaches to software development through the System Development Life Cycle (SDLC). A SDLC is the major concept that fortifies user-oriented software development process. Urgent health care facilities, whether serving children, young people, aged, or emergency cases, require an intricate understanding of local systems. Urgent care facilities are unique in that they serve patients in situations where timely and planned treatment procedures are not possible (NHS Manchester, 2008). Through collaborative contribution to the elements pertaining to a certain urgent health care facility, an efficient information system is achievable. An information system for an urgent care facility should exhibit specificity to the needs of the patients, handiness of use for the staff operating the system, and safety in operation. The information system also helps in prevention redundancy in recording of patient data, and provide s a secure retrieval system, which also stores data on patients for easy recording and modification in subsequent visits. In this report, we consider the urgent department wing of the SFO Medical Clinic, in San Francisco, California. The urgent care arm experiences issues typical of such facilities in the US. The purpose of this report is to document the design and implementation of a new information system for an urgent health care facility. SDLC Models and Complexity of Software Development The SDLC aim is to result in a high quality information system, which meets all user needs and performs markedly better than the existing information systems, manual or otherwise. However, viewpoints differ as to the best model for the system development, a factor that is solely responsible for the

The Modern Prometheus Essay Example for Free

The Modern Prometheus Essay Frankenstein, costing just over $30 million dollars needed to re coup the costs. Therefore changes had to be made; such as the plot, character or action. The director had to edit and cut scenes to make it fit into the one hour and 40 minute time slot. The scenes had to be carefully put together to create a particular style and to create a certain effect. The director edited the scene where the daemon was being created. In this scene there was huge sets, dramatic music and a lot of hand-held camera work and many effective camera angles to capture the enormity of the laboratory. Many images were cut closely together to build up tension and suspense. This was a set piece designed for a modern audience. It is a very visual climax; where as in the book the creation of the monster is shown by, I became myself capable of bestowing animation upon lifeless matter. As a film is intense for a long time and when read a book you graze and they are much more complex; the director has to make it appealing and want to make you watch on. Often commercial pressures mean that the film is not a true or faithful adaptation of the novel. The film Frankenstein is lavish, sumptuous and has high production values. It is full of action sequences and set pieces. Frankenstein is a horror film and its purpose is to scare the audience. But the film cannot be all blood and gore of it would be given an 18 certificate, which would mean that not as many people could see it. Films are censored so that we can restrict groups of society from seeing them. But it is far more difficult to restrict people from reading published novels. In literature authors can truly express themselves. The film s a serious adaptation of the novel and there is an attempt to recreate authentically the period in which the novel is set. There is great care over detail such as costume, sets and props. The first half of the film sets about establishing the relationships, especially between Elizabeth and Victor, this way; if anything happens to them it would have a greater impact on us. It is hard to make a film and still stay faithful to the novel. When reading a novel, the reader has to use his or her imagination to what the characters look like and the background. But in a film it is laid out for you to take in. Because of this most people prefer to read the book rather than watch the film. When the director came to make Frankenstein he had to make a careful decisions about Victors mothers death. In the novel she dies peacefully in her sleep of Scarlet fever, but this had to be changed to fit the film. In the end the director made it, that his mother dies whilst giving birth to his brother. It is very dramatic and looks painful. The stains of blood on the white gown and the birthing chair made the scene very horrific and much more gripping. It also gave Victor and incentive to go and create life and rid the world of disease. The biggest dilemma for the director is to know what scenes to keep and which to change. The directors job is very demanding. The director is the person with ultimate responsibility for everything that takes place on a film set, from the technical aspects up to the movements of the actors. Many directors make a contractual obligation that the released film is their cut. However many directors come under great pressure from the producers to make compromises for commercial reasons. The producers make suggestions in what happens but it is the directors who have the final say in how the film is put together to create a certain effect. The producers represent those who have given financial backing to the film. They can have significant influence on how the film develops. They want to make a high grossing film, with high ratings to bring in the money. The whole project has to be some kind of compromise. The director will highlight the main elements of the novel and remain faithful to those. The rest of the film will be subject to dramatic licence. The film Frankenstein tries very hard to stay to the book. It shows the essence of the novel. The film employs a technique of voice-over briefly at key points within the narrative and this helps to summarise a characters actions, thoughts and motivations. A voice-over can help to cover significant sections of the novel in a short time, as the story is very long and complex.

Compare and contrast plato and decsartes Essay Example for Free

Compare and contrast plato and decsartes Essay Descartes and Plato are two of the most influential thinkers within philosophy. The allegory of the cave and systematic doubt are also two of the most famous concepts within philosophy. Plato at the time of writing the cave allegory was trying to resist the growing influence of the Sophist philosophers who prioritised semantics and rhetoric over truth. 1 Descartes by introducing radical scepticism to philosophy was challenging traditional scholastic philosophy which had dominated the philosophy for many centuries. While both pieces of writing are separated by different ages of time and space, they share many  similarities as well as fundamental differences. This essay will attempt to compare and contrast these two bodies of work by firstly explaining what is Descartes’ systematic doubt and Plato’s Allegory of the cave before finally examining the similarities and differences between them in the final paragraph of analysis. Descartes in his first meditation introduces the concept of Radical doubt which similarly places suspicion on the senses and the appearance of things. This involves stripping away all one’s beliefs and preconceived notions in order to find the foundational bedrock of  knowledge in which all sciences could then grow2. Descartes begins his first meditation by casting doubt on all his beliefs, if a belief can be even slightly doubted it must be discarded. He wants to ‘reject as absolutely false anything in which I could imagine the least amount of doubt3’ this is called radical scepticism where all beliefs must be challenged. Through this experiment Descartes conceded that the physical senses are not to be trusted as they have deceived him before, this is known as sensory deception and this revelation forces him to  doubt any beliefs about the external world and knowledge that is gathered by the five senses. His examination also reveals that dreams states can be difficult to distinguish between waking life, this has happened before where he thought he was in bed but wasn’t. Henceforth one cannot truly know if they are awake observing reality or asleep enjoying a dream, this is known as the dream hypothesis. Descartes also uncovers the evil demon hypothesis whereby all external reality observed may be just an illusion that is perpetrated by an evil demon  seeking to deceive him, also there is the problem that all previous memories about oneself could simply just be imagination and not grounded in any reality. The system of radical doubt leads Descartes into murky territory where he cannot believe in the existence of anything at 1 JULIAS, ANNAS: INTRODUCTION TO PLATO’S REPUBLIC(NEW YORK, 1998)P. 252 2 JOHN, COTTINGHAM, DESCARTES: THE PHILOSOPHY OF MIND(LONDON, 1997) P. 21 3 JOHN CORRINGHAM, DESCARTES: MEDITATIONS ON FIRST PHILOSOPHY (NEW YORK, 2013) P. 33 all. This thankfully is changed when he discovers the cogito’ I think therefore I am’, his  starting point which saves him from uncertainty, allowing him to prove that he exists. In Plato’s allegory of the cave, there are prisoners who are locked up within the depths of a cave. All day long, they are situated in front of a wall and behind them is a fire which reflects shadows on the wall. Unbeknownst to the prisoners, there are puppeteers who use the firelight to reflect shadows of their puppets upon the wall while making noises ‘the truth would be literally nothing but the shadows’4. The prisoners are unaware of this illusion and mistakenly believe these shadows are real images. One day, a prisoner is released from his chains and allowed to walk freely about the cave. Although it is confusing for him to see the puppets and fire, he is forced to accept this clearer version of reality and eventually ascents through the cave, spending a day and night under the sun and the stars. As he becomes familiar with the world above, he realises the sun is the giver of light, how it casts shadows and how his prior life in the cave was an entire illusion. This newfound enlightenment Plato remarks will prevent him from ever returning to the life in cave, nor will his old inmates  believe him if he tried to free him, instead ‘they would put him to death5’ This intellectual awakening will cause the inmate to grasp the idea of good, the eternal form which will urge him to act ‘rationally in public or private life6’. Ultimately Plato suggests the inmate should return to his old friends and seek to help them. The cave analogy is concerned with the human condition and its’ lack of enlightenment7, for Plato the prisoners represent ordinary citizens who hold false beliefs (shadows), reality is dictated to them by their senses (appearance of things) allowing them to be easily manipulated8. Ignorance is then symbolised by darkness and the intellect and reason is symbolised by the light. The journey of the inmate from darkness to light is a metaphor for education which allows one to progress from the ignorance in the depths of the cave to the intellectual plains of the enlightened one in the outside world. The outer world symbolises true knowledge, the realisation of eternal forms while the cave again illustrates the world of appearance and false beliefs, Woozley writes ‘most men without knowing it live in this shadow world’9 4 PLATO.

P. 75. 7 ANTHONY, WOOZLEY: PLATO’S REPUBLIC: A PHILOSOPHICAL COMMENTARY(LONDON, 1989)P206 8 JULIAS, ANNAS: INTRODUCTION TO PLATO’S REPUBLIC(NEW YORK, 1998)P254 The cave analogy and Descartes systematic doubt have much in common. Both are concerned with the illusory nature of the senses and external reality, for Plato people place too much emphasis on the senses, on the appearance of things as illustrated in by the shadows on the wall, this leads them to hold false beliefs and to be easily misled, only by entering the realm of thought can people free themselves by gaining knowledge and becoming enlightened. Descartes through the systematic doubt also maintains that external reality cannot be truly known; the sensory deception and evil demon hypothesis cast doubt on the authenticity of the outside world. Indeed the evil demon hypothesis is an almost identical scenario to that of the prisoners whose sensory perception is distorted by the shadow wielding puppeteers. Only through the mind or intellect can an individual overcome the illusory nature of the senses, it allows the prisoner to access the outside world to gain enlightenment and help his fellow inmates while for Descartes the mind by way of the cogito is the one thing  that cannot be doubted which through it allows him prove the existence of the outside world in his later meditations. The cave is an analogy which illustrates how people can possess false consciousness and how through reason and knowledge one can overcome this while systematic doubt is an instruction on how to discard false beliefs, the ascent through the cave into the intellectual world is the finishing point for Plato while the cogito for Descartes is a starting point for further investigation. The two authors also differ on the type of philosophy employed in their argument. Plato insists that after the ascent , the prisoner will experience the idea of the good ‘ the lord of light in the visible world, and the immediate source of reason and truth in the intellectual’10 the good then is the highest point of knowledge and represents Plato’s philosophy of perfect types or forms known as idealism, Descartes through highlighting the sensory, dream and demon hypothesis illustrates how the external world cannot be relied upon as a basis for true knowledge, but the cogito is a starting point, the attempt to find secure beliefs that allow a foundation for further knowledge to be rested upon  is known as Foundationalism which is credited to Descartes. In conclusion, both Descartes and Plato in their attempts to challenge the prevailing doctrine of their respective times introduced two of the most influential concepts in the world of Philosophy. Descartes through his examination of systematic doubt uncovers the limitations of the physical senses in acquiring knowledge and introduces further challenges to understanding external reality with the dream, memory and evil demon hypothesis. Only 9 ANTHONY, WOOZLEY: PLATO’S REPUBLIC: A PHILOSOPHICAL COMMENTARY(LONDON, 1989)P. 223 10 PLATO. ALLEGORY OF THE CAVE. P. 77  through the mind alone can one grasp the nature of reality starting with the cogito. Likewise Plato is concerned with the appearance of things, how the senses can deceive us and humanity like the inmates in the cave can live in a state of ignorance or darkness if they don’t use the power of the mind to acquire knowledge and reason. Only through using the intellect can humanity gather true knowledge and escape the darkness in the cave. For both the intellect is the only means for gathering true knowledge, the senses are illusory. Descartes systematic doubt and cogito provide the foundational starting point for the sciences while the  cave allegory offers advocates a way of life for humanity to feign the world of ignorance and seek true knowledge so that those who acquire it will return to the cave and help their fellow man.

The Science Of Artificial Neural Networks Psychology Essay

The Science Of Artificial Neural Networks Psychology Essay The science of Artificial Neural Networks (ANNs), commonly referred as Neural Networks, stills a new and promising area of research. The concept of creation of neural networks exists for many decades. Nevertheless neural networks have become known and have been developed in international levels only in the recent years. It is noteworthy, scientist showing interest in neural networks, come from different scientific areas such as chemistry, medicine, physics, mathematics, engineering and the list goes on. That shows Neural Networks is a new challenge in science. No other science today combines and needs direct knowledge from such diverse areas. One of the main differences of the Artificial Neural Networks from the biological is that while ANNs learn through training and experience just like the biological ones but they follow different rules from regular computers. A Neural Network is a parallel data processing system consisted by multitude of artificial neurons, organized in structure s similar with the ones in human brain. They function as parallel computing devices made by many highly interconnected simple processors. Artificial Neurons are mainly organized in layers. The first of those layers called the input layer and is used to insert the data. Input layers are unable to proceed to any sort of computation as its elements do not comprise input weights or bias (threshold). The axon: mean of transfer of neural signals from the neuron. Its length can be tens of thousands of times the diameter of its body and it is characterized by high electrical resistance and very large capacitance. Every neuron has only one axon, however it can branch and thus enabling communication with many target cells or other neurons. The dendrite: short highly branched cell projections (filaments). Most neurons have many dendrites, attached on the soma and increase the surface area. There are approximately 10^3 to 10^4 dendrites per neuron, to receive information from other neurons through synapses they are covered with and transmit electrochemical stimulation to the soma. The axon terminal: located in the end of the axon and is responsible for transmitting signals on to other neurons. On axon terminals are attached the terminal buttons, that store the information in synaptic vesicles and secreting them in neurotransmitters. As mentioned above, the connection between neurons happens through the synapses. Neural synapses are a silent exchange of information. The electrical nerve impulses travel along neurons and transmitted by chemical transmitters (neurotransmitters) in the next neuron across a tiny gap, the synapses and are located between the neuron and the neighboring cell (target cell). Therefore dendrites are very close to each other but never in touch. It is estimated that there are approximately 10 billion neurons in the human cortex, and 60 trillion synapses or connections (Shepherd and Koch, 1990). A number of neurons and their connections form a neural network. The entire system of neural networks in the human body forms the Central Nervous System. This system goes through the whole human body with central points the brain and the spine. During lifetime, synapses are in constant dynamic equilibrium, new are created and old are destroyed. The creation of new synapse happens when the brain acquires more experiences from the surrounding environment, learns, recognizes and understands. On the other side, diseases cause the devastation of neurons and therefore the devastation of synapses. In comparison to other cells, neurons might not replaced by new ones, if destroyed. That means after the birth of a new individual, its neural system is fully developed within the first few months of its life. A neuron can be either active or inactive. When it is activated, it produces an electric signal. This signal has intensity of only a few mVolt. The way those electric signals are produced is pretty similar with the way a capacitor works. Between the external and internal surface of the cell of the neuron there is a dynamic difference. Although the mass of the human brain is only the 2% of human body mass, consumes more than the 20% of the oxygen that goes in the organism. The energy consumption in the brain is about 20 Watt in comparison to a computer that needs a lot more. The computational power of brain is measured by three possible approaches: The number of synapses (Kandel, 1985), the computational power of the retina and multiply it by their brain-to-retina ratio (Moravec, 1998b), and the total useful energy used by the brain per second by the amount of energy used for each basic operation to give the maximum operation per second (Merkle, 1989) From the three approaches above, is concluded that the estimated computational power of human brain is about 10^14 operations per second (Ng, 2009). It is interesting to mention how the electric pulses are created to stimulate neurons. On the membrane of the cell it is appeared to be an electric potential difference between its external and internal surface just like a capacitor. Most of the times the negative charges found in the internal surface as they cant penetrate the membrane and leave the cell. The membrane has many openings that allow ions and atoms to go through each element from its own channel. The endings of the channels are secured by gates which directing the flow of those elements. Proteins that act like pumps force the elements to travel in the opposite direction from their natural and thus neurons consume larger amounts of energy. Eventually the balanced movement of the elements along the surface of the membrane produces an electric current which is the corresponding electrical pulse that stimulates the neuron. Once the neuron has fired it returns to a state of potential equilibrium and in this state it cant be fired again until it recovers. Each neuron has a specific threshold or weight. When electric signals reach that point, sum up and if their weight value is same or larger than the one of the threshold the neuron stimulates. If the sum of the signals is smaller than the required value of the threshold, then the neuron stays inactive. Add images. Models of artificial neurons As mentioned earlier, ANNs are parallel data processing systems, consisting out of large numbers of artificial neurons, inspired by the biological neurons. A neuron is an information-processing unit that is fundamental to the operation of a neural network (Haykin, 1999, pg-10). A neuron may have many inputs, an internal structure consisting out of multiple layers but it always has a single output. Every single neuron accepts variable input signals x0, x1, x2 à ¢Ã¢â€š ¬Ã‚ ¦xn. This corresponds to the electric pulses of the biological brain. Every input signal is multiplied by the synaptic weights of the neuron, wi, where i=1,2,3..n, the input nodes. The weights represent the biological synapses and indicate the strength of the bond (the connection) between them. The range of value of a weight can be positive or negative depending on if the function of synapse suspend or propagate (transmit) the stimuli from other neurons, unlike the biological synapses that do not take negative values. This is because external bias, b, are applied when the weights added. Bias or threshold, is the standard value of the internal potential energy of the neuron that the sum of the combined output must be reached in order the activation (or squashing) function to be activated. An important element of the neuronal body is the adder .At the adder, all the input signals, influenced by weight vectors are summing up together and produce a resultant combined output u. When the sum of weight is big (0 Therefore, the product u is given by the relationship: The result of combined output u, pass through the activation function, denoted with the letter  Ã¢â‚¬  ( ). The activation function is a non linear function where the resultant combined output u takes its final value y. The calculated activation output signal of the neuron is shown as: and where Therefore, Activation functions There are several activation functions, however three of the most basic types are the following 🙠 they slightly vary from book to book) The threshold activation function, which gives as an output 1, if the adder produce a value greater than the one of the threshold. This is expressed as: The Piecewise-Linear function, where the unity is assumed to be the amplification factor inside the linear region of operation (Haykin, 1999, pg:14) The Sigmoid function, which is expressed as: Where  Ã‚ ¡ is is the slope parameter of the sigmoid function. This function is one of the most important and most commonly used as it provides non-linearity to the neuron. Some other activation functions are, the rump function, the bipolar sigmoid function, and the signum function. The signum function gives a positive or negative output, with values usually ranging from 1 to -1 depending on the value of the summation of the weights on the threshold. This can be applied to the activation functions mentioned above and more specifically to the threshold faction giving: Add images and graphs A simple neural network In this paragraph, neural networks will be introduced, starting from their simplest form. Every neural network consists out of hundreds or thousands of tiny units, the neurons. Each neuron has an input where the electric signals are received. A neuron may have more than one input but no matter how many layers of neurons and synaptic connections are in between (the body), there is always one output value. The neurons of a layer between each input and output are not connected to each other however each layer is interconnected with the layer of the next and the previous level. In its simplest form, a neuron has no layers but is limited only to an input and an output. Every signal that leaves an output and enters an input has a value, the weights. The weights represent the importance of each signal reaching the threshold of an input. Depending on the value of weight (wn), the contribution of the electric signal can be great or small for the function of the system. Artificial intelligence and neural networks Historical background (The study of the brain and the biological neurons has started thousands of years ago.) However, as artificial neural networks started to be developing the past century, the historical background still not as broad as in other sciences. The first union of mathematical logic and neuropsychology, commenced in 1943 by Warren S. McCulloch and Walter Pitts. McCulloch was a pioneer neuroanatomist and psychiatrist. Pitts was a young mathematical prodigy, who joined McCulloch in 1942. (Haykin, 1999, pg: 38). Together they created the first model a neural network that was represented by a great number of interconnected neurons. In their well-known paper, A logical calculus of the ideas immanent in nervous activity, (1943), came up with theorems that describe the function of neurons and the neural networks. As a result of those theorems, neural networks and artificial intelligence ideas established a new era of research began. The paper of McCulloch and Pitts, triggered the interest of many scientists like von Neumann, Wiener and Uttley in their effort to extract information of the function of biological neurons and create corresponding artificial ones. In 1949 another idea appeared by D. Hebb who published the book The Organisation of Behavior. Although his book had greater influence on the psychological rather than the engineering community, he introduced the concept of postulate and learning and the synaptic modification rule, which suggests that the connectivity of the brain changes continually thorough its entire life in the process of learning new tasks. From 1950 to 1979, a number of remarkable books were written about neural networks developing the ideas of neurons abilities, such as learning and memorising. Some of these books are the Design for a Brain: The origin of Adaptive Behaviors, (1952) by Ashby, that still exciting to read nowadays, and the Learning Machines, (1965) by Nilsson, one of the best-written expositions about linearly separable patterns in hypersurfaces. (Haykin, 1999, pg: 40). A novel model, the perceptron, introduced in 1958 by F. Rosenblatt. The perceptron is a very simple model of supervised learning, which has only one input and one output built around a nonlinear neuron (Haykin pg 135). Although this model appeared to have many limitations the idea of training the neurons encouraged many scientists for building larger neural networks. In 1969, Minsky and Papert in their book Perceptron they make a complete evaluation of the features and uses of the perceptrons. It proved with mathematics that there were fundamental limitations on the computational ability of single-layered perceptrons and therefore those limitations assumed to carry on in the multilayered levels of perceptrons. A period followed were scientists start losing hope about neural networks and turned to other knowledge based systems. In 1982, neural networks make an interesting come back when John Hopfield proved in a strict mathematical way that by time a neural network can be adjusted to use the minimum energy to function just like human brain does. In addition, Hopfield proved that a simple neural network can be used as storage devise. Such networks are called the Hopfield networks. A very important work was published in 1986 by Rumelhart and McClelland. The two-volume book, Parallel Distributed Processing: Explorations in the Microstructures of Cognitions, shows new methods of training neural networks and introduces the idea of parallel data processor. This theory had a great influence in the use of back-propagation learning as and allowed the development of multilayered networks (perceptrons). The books published by McCulloch- Pitts (1943), Hopfield (1982) and Rumelhart-McClelland (1986), are the most influential in the revolution of neural networks. Since 1980 to nowadays, Neural Networks have been established as a new independent science branch. Conferences and magazines appeared with complete interest on artificial neural networks while the first commercial companies dedicated to the improvement of them, created, supported by thousands of members worldwide especially in America, Europe and Japan.

Coleriges The Eolian Harp Essay -- essays research papers

A single inanimate object, The Eolian Harp, sends Coleridge flitting in, out, over and through introspection. The trajectory of the poem may be plotted as follows: terrestrial observations, fixation upon single terrestrial item (i.e. the harp), exulting single item into transcendence, an astral purview of the terrestrial via the item, reassessment of mind frame, guilt and denunciation of transcendent thought, and finally, remorse and dismissal of all preceding drivel (as to adequately and respectfully embrace the noumenal realm). Coleridge’s brain waves wend in a circuitous manner, however, the final result is a sentiment-shift regarding man’s position before (or, as Coleridge concludes, beneath) God.   Ã‚  Ã‚  Ã‚  Ã‚  Stanza one proffers an apostrophic dupe, as Coleridge calls out to his â€Å"pensive Sara†. Pedestrian predictability would indicate an amorous ode, perhaps asserting (due regard given to the title) that Sara is a form of caution thrown to the wind, thus generating sweet music from aforementioned harp. This is immediately proven incorrect, as seen in the succeeding lines. The first stanza curtails with a descriptive rant, offering a sense of conviction, as though it be a poem unto itself. Lines 10 through 12 read: Snatched from yon bean-field! and the world so hushed!/The stilly murmur of the distant sea/Tells us of silence/. The barrage of exclamation in concomitance with mentions of silence serve as a paradox which ultimately muzzles narration. â€Å"Silence† is apropos in halting a poem, as logic indicates that once a poem reaches its end, the mind ceases churning and goes â€Å"silent†. However, in this instance, it may be construed as poe tic device. Acknowledging that the poem (both literally and figuratively) chimes on, the remaining syllables curiously missing from line 12 are transferred to line 13: /And that simplest lute,/. Coleridge once again takes possession of his narrative, linking the two stanzas with a conjunction. Moreover, this line seethes with audible sound, the only tangibly present noun being â€Å"lute†.   Ã‚  Ã‚  Ã‚  Ã‚  Here, with the commencement of Stanza 2, Coleridge begins to divest himself of earthly bodies as to become engrossed in the harp’s presence. First, the harp is only stationed atop the window’s sill. Gradually, Coleridge introduces the components necessary for the harp to function. At line 20... ...with a return to that with which he began: â€Å"/Peace, and this cot, and thee, heart-honored Maid!/. As asserted by the preceding lines, the so coined ‘holier-than-thou’ God is responsible for all fortunes bestowed upon Coleridge. He has also chosen to reveal to the reader that the entire poem was, in fact, an address to his â€Å"heart-honored Maid†. Conceivably, Coleridge has addressed her as such in order to absolve himself of any perceived wrong-doing; specifically in Line 15: /Like some coy maid half yielding to her lover,/. Distinguishing between â€Å"maids†, (one being a trollop, the other a lady of virtue) is a final attempt to get himself ‘off the hook’, colloquially speaking.   Ã‚  Ã‚  Ã‚  Ã‚  As delineated in paragraph one, Coleridge’s poetic field is one rampant with erratic thought and ultimate change. The proposed subject of the poem, an eolian harp, is virtually abandoned and replaced with veneration of a God as well as a lover. One would think that such a fickle publication would be kept isolated by its author. Although, Coleridge may have staked importance in showing his adoration for God publicly. Hence, the ingress and resultant revocation of the Eolian Harp.

Coleridge once again takes possession of his narrative, linking the two stanzas with a conjunction. Moreover, this line seethes with audible sound, the only tangibly present noun being â€Å"lute†.   Ã‚  Ã‚  Ã‚  Ã‚  Here, with the commencement of Stanza 2, Coleridge begins to divest himself of earthly bodies as to become engrossed in the harp’s presence. First, the harp is only stationed atop the window’s sill. Gradually, Coleridge introduces the components necessary for the harp to function. At line 20... ...with a return to that with which he began: â€Å"/Peace, and this cot, and thee, heart-honored Maid!/. As asserted by the preceding lines, the so coined ‘holier-than-thou’ God is responsible for all fortunes bestowed upon Coleridge. He has also chosen to reveal to the reader that the entire poem was, in fact, an address to his â€Å"heart-honored Maid†. Conceivably, Coleridge has addressed her as such in order to absolve himself of any perceived wrong-doing; specifically in Line 15: /Like some coy maid half yielding to her lover,/. Distinguishing between â€Å"maids†, (one being a trollop, the other a lady of virtue) is a final attempt to get himself ‘off the hook’, colloquially speaking.   Ã‚  Ã‚  Ã‚  Ã‚  As delineated in paragraph one, Coleridge’s poetic field is one rampant with erratic thought and ultimate change. The proposed subject of the poem, an eolian harp, is virtually abandoned and replaced with veneration of a God as well as a lover. One would think that such a fickle publication would be kept isolated by its author. Although, Coleridge may have staked importance in showing his adoration for God publicly. Hence, the ingress and resultant revocation of the Eolian Harp.

Political Conflicts in Washington :: Poltical Conflict, Obama

Political conflicts regarding oversight are becoming a common occurrence in Washington, but have you stepped back and analyzed why this is? These unnecessary strangle hold on the democratic process are due to a few common practices, party politics, a deference to the Executive Branch, and prioritizing voter concerns with wasteful government spending. Some cause more problems than others, but overall these are the three biggest causes. Party politics prevents Congressmen and Senators alike from rearing off the path of their political party stance. We also see voters own ignorance as a big part of the government waste problem. Many like to complain about problems in our laws, but then are supportive of the laws when they go through Congress. This makes it very easy to pass laws with waste because they know the general population most of the time will let it slide. If your party holds the presidency, but that president does something that is unconstitutional that party will most likely stand its ground supporting the president. While the Executive Branch is an office that deserves respect, respect cannot get in the way of the Constitution and the laws of the land. No one is above the law, especially people in high office if anything they should be held more accountable due to their importance in American life. Congressional oversight is a major part of the checks and balances system, and if these major problems continue to occur we will see more and more people abuse the American democratic process. As long as there has been a two party system there has been party politics. This phenomena by definition is a Congressmen (Be him or her Democrat or Republican) is so loyal to the party that they will vote for those bills, or resolutions, or whatever just because their party supports it. This becomes problematic when you want to express what is best for your constituents, but may not be what the party is pushing for. This makes a very lazy Congress no matter the party, bills can go through that are not what are best for his or her distract but for the good of the party. Out of the three factors, this is the one that hinders Congressional oversight the least. While this is a problem it doesn’t hit the factor of oversight hindrance as much as the other two. This practice is becoming more common every year, and because of that it’s almost unheard of for Democrats or Republicans to vote outside of their party lines.

Graphics Packages :: Computers Technology

Graphics Packages Graphics is a word used for all the different types of artwork, such as photographs, graphs, charts etc. Graphics packages Graphics packages may not be as detailed as you think. It can be a simple paint package, which has features of shading, drawing line diagrams and many other simple but effective features. These packages can be an alternative to complicated DTP packages. As it is very difficult to draw with the mouse, many people scan the drawings on the computer and now there are software packages, which do not use a mouse. New equipment used by professionals so that they can get pictures from a variety of places. A video grabber lets you get pictures from the television or a video camera and you then can alter it on your computer. A digital camera is also very popular as you can take pictures and then put them on your PC and alter then. This also means that you do not have to pay for the developing cost. You can also use clip art for pictures. Bit map vector graphics When using a graphics package the graphics file can have the image represented as a: 1.Bit map 2.Vector image A bit map files makes every dot or pixel on the screen has a single bit of information in a file. If it is in colour, you then need to store additional bits. The disadvantage to this is that if you want to alter anything you have to change it at a pixel at a time. When you enlarge an image, the number of pixels stays the same. In vector graphics, the lines are stored as equations on the computer. They are stored in vectors. The advantage of vector graphics over bit map files is that it is easy to alter things without any loss in resolution. When you enlarge an image, the number of pixels increases to the proportion of the image. CAD packages use vector images. Clip Art Clip Art is a collection of copyright-free drawings which you can place on your drawings. The drawings on clip-art look very professional, as they have been drawn in detail. Presentation software Pictures let you give ideas and concepts a better understanding than only words. Good presentations use things such as slides and transparencies to express views. A projector could be used for a large audience or a rolling slide show could be produced on a computer for smaller audiences.
