ROSE FOR EMILY-PSYCHOLOGICAL INTERPRETATION essays

ROSE FOR EMILY-PSYCHOLOGICAL INTERPRETATION essays William Faulkner (1897-1962) is known in the world of literature as the "historian of the negative" and narrator of the dark. In other words, Faulkner was obsessed with the dark side of human mind and in his in-depth psychological exploration of such areas; he would produce stories that were often violent and negative. While his celebrated contemporary, Ernest Hemingway would also focus on psychoanalysis of characters; his stories were closer to reality unlike Faulkner's who believed in shocking his readers and taking them by complete surprise. Most of his works have a sinister air about them as if the author is foreshadowing a really dark and appalling ending. In this paper, we shall study three different pieces of writing by William Faulkner to comment on the writer's style and explain the use of common themes and devices. Faulkner has been associated with thrilling mysteries where he would bring out something evil in the characters. His fascination with the darker side of human mind is evident from his works including his most famous short story, A Rose for Emily. Here Emily stood for twisted human psyche, which leads to bizarre happenings. The author's style is mysterious as if he is trying to hide something all the time, only to take his readers by complete surprise in the end. Faulkner would often keep his work deceptively simple just to maximize the impact of the last twist in the plot. This is exactly what happens in A Rose for Emily where Emily is shown as a simple mysterious woman who didn't like intrusion or interference in her life. However her unusual existence is quite intriguing and give birth to various stories about her. The author in all his works tries to create an unreal world with the help of weird characters, whose actions cannot be justified by anyone but themselves and who are real enemies of natural order'. In Rose for Emily, it is Emily who suppresses her d...

Building of professional competence - Essay Example According to the research findings it can therefore be said that communication remains one of the vital elements to every professional in conducting his daily activities. Communication needs to be very effective in businesses in order to create a mutual exchange of understanding between the conveyer of the information and the readers. Business communication ensures that there is constant flow of information. More than often, communication plays an important role in giving information to the interested parties of an organisation including employees and shareholders notwithstanding the general public. In the presentation on Harrods holdings, effective communication was made to various parties. This comprised of the customers who were served in Harrod holdings and investors who were the key shareholders in the company. With regards to the customers the report gives information based on the location of Harrod holdings within its business actual position in the market. In addition, the co mpany’s managers give a convenient highlight on the presence of other boutiques that Harrod holdings have around other parts of the world. The report given based on Harrod holdings also shows the owners of the company thus, giving the public the image of the company. year that it was founded as well as the year and place of incorporation; this shows the depthness and clarity of giving information. Through the report we have learnt on the significance of improving our interpersonal communication skills. Working with others In coming up with a report on Harrods holdings the staff worked together in groups to manage the company’s sales portfolio. In this group every individual exhibited a high level of corporation as it is highlighted by the high volumes of sales. Working in a team combines the skills and the creativity of a diverse number of individuals in the group. Teamwork is the key to the success of every team. During our reporting on Harrod holdings we devised a te am process, roles and behaviours. In managing a team all members occupational obligations are supposed to be considered, thus, working out the time into each member busy schedules remains important in working as a group. In the meeting, determination of members strength and weaknesses assisted greatly in task allocation. We owe the success in our team to our abilities to compliment each other and distribute tasks accordingly. In the team we had cohesiveness and productivity given that our final common goal was set. Improving own learning performance More than often, individuals set out standards that are geared on improving the learning performance. As a result, the study on Harrod Holdings was able to set out standards based on key skill that we identified over time within the activities carried by employees. These skills have assisted the company in developing themselves as independent learners from within the group members especially, as the employees focused on achieving the goa l of giving an increased sales production to Harrod Holdings. This is relevant in the presence of process skills that focus on target-setting through effective planning. Later on, we focused on process skill advanced to learning of new techniques

Strategic Management Decisions Assignment Example | Topics and Well Written Essays - 5000 words

Strategic Management Decisions - Assignment Example The rapid sociological changes also contribute to the changing business environments, especially with respect to the entertainment market. Governmental policies and laws also affect where and how firms choose to compete. All these factors affect not only the general competitive environment in which the firm is operating but also the strategic decisions made by companies to combat the competition within the industry. In general the business strategies are based on the firm's ability to capture and convert the external and internal forces into desired outcomes. Thus "an integrated understanding of the external and internal environments in which the firm is operating is essential for the firm to understand the present and predict the future."(S.A. Zahra & Geroge 2002) A firm's external environment can be broadly divided into general, industry and competitor environments. "The general environment is composed of dimensions in the broader society that influence an industry and the firms within it" (L.Fahey 1999). These dimensions can be grouped under the following environmental segments: For formulating strategies to steer the firm through the challenges being posed by these environmental forces, a careful evaluation of the firm's strengths in these areas need to be analysed and for that purpose the 'PESTLE' analysis comes handy. An in-depth analysis of the firm's competitive ability is one ... PESTLE analysis like the PEST analysis involves identifying the political, economical, socio-cultural, technological, legal and environmental influences on an organization. PESTLE analysis is simple, quick and uses the basis key perspectives of an organization. The advantage of this tool can be found in encouraging the management to adopt proactive and structured thinking in its decision making process. 1.3 PESTLE Analysis with respect to Live Entertainment Market in UK: Mintel reports that in spite of the stiff competition from other form of entertainments, live entertainment still holds the centre-spot with 48 percent of the UK adults are in favour of live entertainment and 54 percent of them have attended a live music, a play, a stand-up comedy or karaoke in the past six moths. Even among these the live music is proved to be the most popular type of event. Political: Any changes in the governments would affect the policies relating to rates and taxes on the entertainment business may affect the general growth of the business as being a leisure sector usually subjected to additional tax burden. There may be changes in monetary policies due to political reasons that may result in exchange fluctuations to have an impact on the profitability of Live Nation as Live Nation is basically a non-UK origin entity, Economical: The predictions for the UK economy till the year 2010 are that there will be a continuous growth of 2-3 percent annually in the consumer expenditure despite a slowing down of the economy and the personal disposable income is also expected to increase by 3-4 percent. These two variables have a definite positive impact on the consumers' willingness to spend on leisure activities including live music. The other economic factor that may

Differences in Grid and Air Gap Techniques

Differences in Grid and Air Gap Techniques Introduction In this chapter, a literature review was carried out so that adequate information about the differences in grid and air-gap technique could be gathered with emphasis on why these techniques are important in plain radiography of the lateral hip. These two techniques will be analysed to explain better the acquisition of the image. Both techniques will be compared and their advantages and disadvantages discussed. This was done by means of radiography books and journals. Where, possible primary sources of information were chosen. However, original studies could not always be obtained and secondary sources had to be considered. The use of the internet was also important as it served as a source for and access to relevant articles. Related literature was mainly sourced using the online data bases of EBSCO ®, CINHAL ® and Pubmed ® as well as the Institute of Health Cares library and facilities. Image quality Image quality refers to the ability to view the anatomical structure under study with precision and which makes it possible to identify and spot any abnormalities (Bushong, 2008). The quality of the image depends on several physical and physiological factors and this makes it hard to measure. Image quality; Is defined in radiological terminology as the relationship between the structures of a test sample to be irradiated with x-rays and the parameters of its visualisation (Hertrich, 2005, pg.244) According to Bushong (2008), the most important factors that improve or degrade image quality are contrast resolution, spatial resolution, noise and artefacts. Image quality cannot be measured in a precise way since the quality of radiographs is hard to define (Bushong, 2008). In digital radiography (DR) the image quality depends on a number of characteristics that can change the viewing experience. One of these factors is frequency, which is a measure of the total amount of contrast within the image. This characteristic depends on the raw data (x-ray energy) that the imaging detector absorbs. The frequency of the image is represented by different grey scale levels that show the density of a particular part of the anatomical structure. This is how contrast is affected. A high contrast image has high frequency due to the amount of x-ray photons absorbed (Carlton Adler, 2006). Image quality is also subjective and depends on the viewer (Sherer et al., 2006). Different people may need to alter the quality of the image by increasing or reducing the contrast or by changing the sharpness of the image depending on their individual visual abilities (Dendy Heaton, 2003). Dendy and Heaton (2003) argue that image quality also depends on the display system and the way the image is produced. The authors further argue that room lighting also affects image quality and might also diminish image quality. Image contrast Image contrast refers to the difference in densities between adjacent anatomical structures. The amount of contrast produced on an image depends on the structural characteristic of the anatomical part of the body as well as the characteristics of the x-ray beam when it penetrates the patients body. Contrast depends on the attenuations within the patients body due to different densities in various parts of the body. The higher the difference in densities, the higher is the contrast (Sherer et al., 2006). However, small changes in densities of structures would not be detected on a high contrast image since high contrast does not have a great enough exposure latitude to give several shades of grey in the image (Bushong, 2008). This means that having high contrast in an image does not necessarily mean that it is optimal for every radiographic examination. Having low contrast means that better contrast resolution is produced and this gives the viewer the ability to differentiate between a natomical structures that have similar densities. This is why contrast is a very crucial factor in image quality (Oakley, 2003). Scattered radiation affects image contrast and the characteristics of the receptor and display system. The anatomical detail and contrast of small anatomical structures may also be reduced due to image blurring (Carlton Adler, 2006). Noise Noise affects the images contrast resolution and the detail seen in the image. Like audio noise and video noise, radiographic noise is caused by weak signals in areas of the image (Oakley, 2003). The lower the noise the better the contrast resolution and so image quality is better. According to Bushong (2008), there are four main components that affect radiographic noise. These are graininess, structure mottle, quantum mottle and scatter radiation. Graininess and structure mottle cannot be controlled by the radiographer since they are dependent on the image receptor. However, the radiographer can use several techniques and exposure factors to improve image quality and reduce the noise as much as possible depending on the subject under examination. Penetration energy of the x-ray photons (kV) can be increased in subjects that are obese and that are having thick areas of their bodies irradiated. Quantum mottle is also a very important characteristic in defining noise. Bushong (2008) ex plains that quantum mottle depends on the amounts of x-rays that are exposed and absorbed by the image detector. When few x-rays react with the receptor the resultant image will appear mottled. However, when more x-rays are absorbed by the detector, the image will appear smooth. Noise can be calculated by measuring the signal-to noise ratio of the image (Bushong, 2008). If not enough x-ray photons reach the detector, the image is said to be under-exposed, resulting in a low signal-to-noise ratio. However, a high signal-to-noise ratio is achieved if the right radiographic technique is used with the right exposure factors (Bushong, 2008). Spatial Resolution Spatial resolution is a term used in imaging that refers to the resolution of a radiograph. Having a high resolution means that more detail can be seen and detected on the image. Spatial resolution is a very important performance indicator in radiography. Quality control phantoms are used to check the spatial resolution and contrast of an imaging system. Spatial resolution relies on spatial frequency and this quantity could be calculated by seeing the number of line pairs per millimetre (Lp/mm). These line pairs are dark and white lines that are used to assess the resolution of an image. Detail is very important in radiography since outlines of tissues, organs and specific pathologies need to be sharp and detailed. High spatial resolution is also important when assessing for subtle fractures like scaphoid fractures which could easily be missed if the radiograph is not sharp enough (Bushong, 2008). Scatter Radiation When x-ray irradiation encounters matter, some photons pass unimpeded reaching the image receptor whereas other photons are completely absorbed since the energy of the primary x-ray beam is deposited within the atoms comprising the tissue. This absorption interaction of x-ray photons with matter is known as the photoelectric effect (Fauber, et al, 2009). This photoelectric effect is dependent on the matter and its effect decreases rapidly with increasing photon energy (Dendy Heaton 2003). Scatter radiation is made up of photons that are not absorbed but instead lose their energy during interactions with the atoms making up the tissue (Fauber, et al, 2009). This scattering effect is known as the Compton effect (Carlton and Adler, 2006). This happens when the incoming photon interacts with matter and loses energy. This will make the photon change direction and it may leave the anatomic part to interact with the image receptor (Fauber et al, 2009). Scattered low- photon energy reduces the contrast on the final radiograph and is also highly hazardous for patients and staff due to its changed direction and low energy from the primary beam (Dendy Heaton, 2003). Scatter Reduction As explained above, scatter radiation is produced during a Compton interaction in which a primary photon interacts with an atom of the patients body and loses its speed and direction. Scatter is produced mainly in the patient due to the variable attenuation and densities of the different organs in the body and this could be controlled by using anti-scatter techniques and the right exposure factors. Consequently the radiographer should use the adequate technique and exposure factors to reduce the radiation produced within the patients body. Carlton and Adler (2006) argue that when the energy of the primary beam is increased there is a higher chance for the photons to undergo the Compton interaction. This means that the higher the energy given to the photons (kV) the more likely it is that there is Compton interaction with the bodys atoms, therefore creating more scatter radiation and a decline in radiographic contrast (Bushong, 2008; Carlton Adler, 2006). However, Shah, Hassan Newma n (1996) think otherwise. In their study they stressed the effectiveness of anti-scatter techniques on image contrast and concluded that the influence of kV on scatter production is small. The authors further stated that the improvement in contrast that occurs when the kV is lowered is usually due to an increased subject contrast since less scatter reaches the film. Carlton and Adler (2006) also gave importance to the size of the area of body being irradiated. They suggested that by decreasing the area of irradiation as well as applying compression, scatter radiation reaching the detector could be significantly reduced. Using this technique Shah, Hassan and Newman (1996) noted a decrease in the dose area product (DAP) when decreasing the area of irradiation, therefore lowering the risk of increasing patient dose. Anti-scatter techniques Anti-scatter techniques are radiographic techniques that make use of devices or applications such as grids and air gaps so that scatter radiation is absorbed or deviated from reaching the image detector. These anti-scatter techniques help in reducing patient dose as well as improving the quality of the radiographic image. The two main techniques relevant with this study are explained and analysed in the following sub-sections. Grid Technique Grids are used in radiography to protect the image detector from scatter radiation. Scatter radiation degrades the quality of the image and may lead to loss of anatomical detail and information (Sherer et al., 2006). Anti-scatter grids are made up of parallel radio opaque strips with a low-attenuation material interspacing the strips (Sherer et al., 2006). The most commonly used interspaced materials are aluminium and carbon fibre (Court Yamazaki, 2004). The main function of these anti-scatter grids is contrast improvement. According to Carlton Adler (2006), the most effective way to see how well a grid is performing is by measuring the contrast improvement factor. The contrast improvement factor measures the ability of a grid to improve contrast. This factor is affected by the volume of tissue irradiated and by the kV. If the amount of scatter radiation increases, the contrast of the image will be reduced, therefore reducing the contrast improvement factor. This is calculated usin g the following formula: K= Radiographic Contrast with the grid/Radiographic contrast without the grid (Carlton Adler, 2006, pg.263) The higher the contrast improvement factor the higher is the contrast improvement. However, Court and Yamazaki (2004) argue that since contrast can be digitally altered in digital radiography, it is best to calculate the signal-to-noise ratio (SNR) of the image. This is especially useful in cases where there is low object contrast. The interspaced material separating the lead grid lines is also very important in monitoring the functionality of a grid. In the study performed by Court and Yamazaki (2004) it was concluded that aluminium has a higher atomic number than carbon fibre and so it absorbs more low energy scatter radiation. However, aluminium also absorbs some of the primary photons therefore increasing patient dose. Alternatively, carbon fibre absorbs less primary radiation than aluminium (Court Yamazaki, 2004). Grid ratio is also an important factor to consider in improving image quality especially image contrast. The grid ratio is obtained by dividing the height of the strips by the strip separation. As the grid ratio affects the rate of scatter to that reaching the detector it is instrumental in improving image contrast (Dendy Heaton, 2003). There are principally two types of grids, linear grids (parallel grids) and focused linear grids (Fauber, 2009). Both types have their own advantages and disadvantages. Parallel grids are made up of linear lead strips with low-density material interspacing them and are parallel to each other. This variety of grids produces grid cut-off at lateral edges since they do not coincide with the oblique divergences of the beam (Dendy Heaton, 2003; Fauber, 2009). It is also essential that these grids are positioned correctly, perpendicular to the central ray of the primary beam. If this is done incorrectly, there will be grid cut-off and the lead strips will absorb a lot of the primary beam which will show up on the image (Dendy Heaton, 2003). This will result in image deterioration and in the patient receiving an extra dose of radiation when repeating the exposure. The focused grids, however, are designed in such a way that it allows the lead strips to be gradually angled moving away from t he central axis. Although these grids are designed to eliminate the cut-off on the lateral sides, they still have to be used at a specific focus to image distance (FID) depending on the type of grid being used (Dendy Heaton, 2003). Although grids are used to improve image contrast and reduce scatter reaching the detector, this is at the expense of a high radiation dose to the patient. This happens because the mAs has to be increased when using the grid. This is necessary in order to compensate the primary beam photons absorbed by the grid (Carlton Adler, 2006). Air-gap Technique The air gap technique is an alternative technique used to reduce the amount of scatter reaching the detector. By employing an air-gap technique between the patient and the image detector, the energy of the scattered photons decreases especially in the first tens of centimetres due to the large divergence of the beam (Ball Price, 1995). The primary radiation is not affected or reduced, since at this stage the primary beam is almost parallel to the detector (Ball Price, 1995). When the air-gap technique is used, the object to image distance (OID) is increased, which may produce some magnification (Sherer et al., 2006). Anti-scatter techniques are important in reducing low energy radiation reaching the detectors. However, the primary beam should not be deflected or disrupted so that the image acquisition and image quality is not affected (Fauber, 2009).When the grid technique is employed, the grid lines are unable to discriminate between the primary radiation and the scattered radiation and so this could lead to grid cut-off and grid lines may appear on the image (Maynard, 1981). Maynard (1981) argues that with the use of an air-gap the image quality and diagnostic quality of many projections improves. A study by Karoll et al. (1985) analysed the patient dose when the air-gap was employed compared to when the grid was used. In this study the air gap was employed in a digital subtraction examination. Karoll et al. (1985) reported that by using the air gap technique the mA could be lowered without losing spatial resolution. The results of this study were remarkable as the air gap technique allowed 25% to 88% reduction on the mA without increasing the kV or the time of exposure (Karoll et al., 1985). This meant that patient dose was reduced since the mA was lowered and so the patient was irradiated less. Although this study is 25 years old, it is still valid since in direct digital radiography, windowing has given the radiographer the possibility to reduce the exposure factors to a certain limit while still obtaining a good diagnostic image. This means that patient dose could be lowered. Both grid and air-gap technique were studied and compared to assess patient dose by Kottomasu and Kulms (1997). The authors concluded that the air-gap improves musculoskeletal digital imaging without an increase in skin entrance dose. According to Kottomasu and Kulms (1997), this happened since the scattered photons had less energy once diverged by the patient; they were deflected and did not have enough energy to reach the image detector (Kottomasu Kulms, 1997). Barall (2004) also suggested that when employing the air-gap technique the radiographer should apply inverse square law by increasing the SID and applying tighter collimation. This will ensure the highest decrease in patient dose possible (Barall, 2004). The increase in SID could enable a better use of the air gap while reducing magnification by keeping the source to object distant (OID) constant. In relation to the horizontal beam lateral hip projection, there is a reduction in dose and a good diagnostic resultant image wh en compared with the grid technique (Barall, 2004). Trimble (2000) concluded that imaging the thoracic spine without a grid was possible in children and adults of small size. In this study a significant dose reduction was noted and therefore on this basis, imaging the hip laterally using a horizontal beam and applying the air-gap technique instead of the grid may also result in a reduction of patient dose as opposed to using the grid technique. Digital radiography Radiography has been revolutionised and developed throughout the years from screen film (SF) radiography a high quality digital system has evolved (Oakley, 2003). With the introduction of digital imaging systems, image quality characteristics have improved. The process of image formation in DR is similar as in SF. The image is first generated, then processed, archived and presented. Instead of films, DR uses detectors which when exposed to x-ray radiation absorb this irradiated energy which is then transformed into electrical charges, recorded, digitized and configured into different grey scales (Dendy Heaton, 2003). The grey scales presented on the produced image represent the amount of x-ray photons absorbed by the detector. A big advantage in digital radiography is image manipulation post-processing. While viewing the image, the radiographer can zoom in or out, change the greyscale as well as use measuring tools. Another great advantage of DR over SF is that images can be stored safely and archived. This solves the problem of films being lost and enables future reference of the images (Carlton Adler, 2006). There are two types of digital imaging systems: computed radiography (CR) and direct digital radiography (DR). In computed radiography imaging plates containing photostimuable crystals are used, which absorb the x-ray energy and store it temporarily (Kà ¶rner et al., 2007). Processing involves scanning the detective layer pixel by pixel using a high energy laser-beam of a specific wave-length. Since the exposed photon energies are only stored temporarily in the detective layer, the read-out process should start immediately after exposure. This is mainly because the amount of energy stored in these crystals decreases over time. Although this is a big step from screen-film (SF), spatial resolution in CR may decrease if viewing monitors are not of the appropriate resolution (Kà ¶rner et al., 2007). Direct digital radiographic systems use a photoconductor directly converting x-ray photons to electrical charges, once the photons are absorbed. The most common material used as a photoconductor in industry is amorphous selenium. This material has a high intrinsic spatial resolution. However, the material of the detector does not affect the pixel size, matrix and spatial resolution of the detector (Dendy Heaton, 2003). These are affected by recording and read out devices used. Therefore image processing in DR is as important as in SF and CR. In DR image processing is used primarily to improve the image quality by removing technical artefacts, optimising the contrast and reducing the noise (Dendy Heaton, 2003). Radiation Dose The transition from SF to DR has also changed the radiation dose that the patient gets from an x-ray exposure. Radiation dose is the amount of radiation absorbed by the patient due to a radiation exposure (Carlton Adler, 2006). In SF radiography the dynamic range of the receptor (film) is relatively low and so it only detects specific exposures that lie within its parameters. However, in DR the digital receptor can detect a wide range of exposures. This means that a slightly underexposed or overexposed image is acceptable since image quality can be altered using windowing. Therefore in DR the radiation dose could be kept relatively low when compared to SF while still producing a good diagnostic image. This could also work the other way when patients are overexposed to radiation due to the wide dynamic range of the receptors. The ALARA concept is based on the theory that there is no safe dose of radiation using any kind of irradiation or radioactive material (The Ionising Radiation [ Medical Exposure] Regulations, 2000/2007 The Medical Exposure Directive 97/43/Euratom). In this way individuals internal and external exposure to radiation is kept to a minimum. This principle does not only address radiation used in medicine but also social, technical and economic considerations of use of radiation. This principle also takes into consideration the time of exposure of radiation, filtration, and appropriate materials selected to minimise radioactivity depositing on surfaces. This also ensures the safe disposal of materials containing radioactivity such as needles used in nuclear medicine (The Ionising Radiation [Medical Exposure] Regulations, 2000/2007, The Medical Exposure Directive 97/43/Euratom). The use of ionising radiation should be monitored and used carefully to ensure as low a dose exposure as is reasonably achievable to the patient while at the same time producing an image of high diagnostic quality. Relative Literature The latest literature reviewed in relation to this dissertation was that of Flinthman (2006) who assessed thirty-five horizontal beam lateral hip radiographs for image quality. Nineteen of the cases were performed using the air-gap technique whereas sixteen using the grid technique. Several radiologists and radiographers were asked to evaluate the images. It was found that the air-gap was of higher image quality than the grid technique (Flinthman, 2006). In Flinthmans study several persons were asked to evaluate an uneven number of cases that were meant to be compared regarding the technique used to obtain the radiographs. According to Flinthman (2006) it is more important to have a small group of people evaluating the radiographs. This is because the results could be more specific and more reliable (Flinthman, 2006). A limitation of this study is that Flinthman (2006) did not use the same subjects in both techniques to achieve his results and so it is harder to attain valid and conc lusive results that could be applied in a clinical setting. A similar study comparing the grid and air-gap technique was conducted by Persliden and Carlsson (1997). Persliden and Carlsson (1997) studied scatter reduction using the air-gap and the grid technique. This study investigated the effect of the air-gap technique over the imaging plate and demonstrated the positional variation of scattered radiation (Persliden Carlsson, 1997). The authors concluded that by using the air-gap technique, the patient irradiation was lowered. Persliden and Carlsson (1997) argued that even field size and patient thickness greatly affected the use of the air-gap. As well as Persliden and Carlsson (1997), Trimble (2000) looked and assessed image quality of lateral thoracic spine radiographs and chest radiographs. These examinations were both done using the grid technique and the air-gap technique. Trimble (2000) found it important to have a large sample of subjects while keeping the specialists evaluating the images small. Trimbles study resulted in the air-gap being better for high image quality than the grid. Similiar to this study, Gouldings study (2006) who looked at image quality in lateral hip radiography when using both grid and air gap technique. The radiographs were obtained from the accident and emergency department Goulding (2006) worked in, where radiographers performed lateral hip shoot through examinations using their preferred air gap or grid technique. Goulding (2006) took a sample from the recorded examinations of both techniques. The researcher excluded examinations with an exposure of 100 mAs or more as well as any duplicate patient numbers due to re-assessment as well as those examinations that used both air gap and grid technique in the same examination as this signified a very large patient. Goulding (2006) compared the sampled gird and air gap radiographs after reporting radiographers evaluated five areas on each radiograph, chosen by the researcher. The radiographers had to score each area from one to five where one is poor and five is optimum. It resulted that the a ir gap technique had improved image quality more than the grid technique. A limitation of this study was, however, that the patients used to test for both techniques were not the same, and so this could have meant that the results were not totally reliable since patient size and exposure factors were not constant but varied depending on each examination. Conclusion The literature reviewed in this chapter has explored furthermore the roles of the air-gap and grid technique in imaging. It has also analysed the effect of scatter radiation and ways to reduce this in order to improve radiographic image quality while limiting the radiation dose to the patient as much as possible. Several studies were reviewed and analysed and will help to improve this experimental research. Some studies that are similar to this study were reviewed and discussed. In the next chapter, a description of the research design used in this study will be presented.

Ontomorph: Mind Meets The World :: Philosophy Science Papers

Ontomorph: Mind Meets The World Chunking of the world as done by the mind depends on how the world is. The world is one object, but not a simple one. Morphological content is just right to allow organisms which move in the world to perform the appropriate dynamical chunking, which from the perspective of the higher cognition may appear to consist of several separate objects. Embracing nonreductionism is desirable because organisms are part of the world. At bottom, there is nothing else other than physical stuff. But it is possible, and indeed it is true, that the physical stuff is very richly structured. One kind of physical stuff are things such as minds. The intricate structure of minds, particularly the complicated topography of their multidimensional space is ultimately responsible for qualitative experiences and consequently for the hard problems of consciousness. As the space of morphological content is itself a part of the physical world, it can begin to throw light on this problem and primarily at the quali tative states — as products of encounter of one form of physical stuff, organisms, with the rest of the physical stuff around them. Some surfaces of the world are moulded and shaped in their encounter other surfaces in the world. But the world has many dimensions; some surfaces are richer than others. The purpose of the shaping is the tacit expectation of further encounters with surfaces in the world. I. Bringing Ontology Of The World And Cognition Together The issues of ontology and cognition are tackled in a separate manner. "As I try to think about the issues in cognition, I try to exclude the issues about how the world is" is an often adopted attitude. This does not mean that investigation of the mind would be extraneous to ontological questions. Quite to the contrary. A respectable contemporary philosopher would normally adopt physicalism as a hypothesis about the mind, thus embracing a materialist ontology. A materialist treats organisms possessing mind as parts of the physical world. The way how the problem is posited then generates a question about the persisting explanatory gap, or about the reductionist hard problem: All in being treated as a part of the world, organisms possessing mind still differ from the World in that they have consciousness consisting of qualitative experiences which are not reducible to the physical World. So one may wish to be a nonreductionist concerning the ontology of mind.

Supply and Demand and Budget Line

TASK 1 Consider the following equation: MRSXY < PX/PY where MRS = marginal rate of substitution x and y are two goods P = price < = is less than {draw:frame} The graph above shown us the indifference curve budget line diagram which explaining the equation MRSXY < P X / PY. There are two ways to measure the consumer preferences or what the consumer wants. The first one is by trying to put a ‘value’ on the satisfaction a consumer obtains from consuming a ‘unit’ of a good. Consumers are assumed to be able measure utility in terms of a ‘util’. However, we cannot find the total utility by using this method. So we can use another way which is by ranking the product. We can say that the consumer is preferred good Y compared to good X. the indifference curve is a curve that shows consumption bundles that give the consumer the same level of satisfaction. So this means that the consumer is satisfied at any point if the indifference curves above. The slope of the indifference curves are downward sloping. For example, the consumer will satisfy when he buys 3 good X and 4 good Y. The meaning of the term budget constraint is what the consumer can afford to buy. The income of the consumer will determine how much he can buy in the market. So, the budget line in the graph above is showing how much good X and Y that the consumer affords to buy. If the slope of the budget line is higher, this means that the consumer afford to buy good X compare to good Y. While if the slope of the budget line is lower, the consumer afford to buy good Y compare to good X. From the graph, we can see that the consumer is not maximizing the satisfaction. This is because the indifference curves are inside the budget line and it intersect at two points which are a and b. At point b, the slope of the indifference curve (MRSxy ) is less than the slope of the budget line (Px/Py). While, at point a, the slope of the indifference curve (MRSxy ) is greater than the slope of the budget line (Px/Py). So the consumer does not maximizing the satisfaction for both point a and b. In order to maximize the satisfaction, the slope of the indifference curve must equal to the slope of the budget line. So at point b, the consumer should reduce the consumption of good X and increase the consumption of good Y until both slope of indifference curve and budget line will become the same. By switching spending away from good X towards good Y, the consumer will be able to reach a higher indifference curve. {draw:frame} From the graph, we can see that the indifference curve has shift and meet the budget line at the point c. at this point, the slope of the indifference curve and the budget line are the same. So the equation will change to [MRSXY = PX / PY]. At point c, the consumer satisfaction is at the highest place. The consumer choice is the product which been sold in the market. While, the individual demand for a product is the demand of a consumer on that product. The demand on a product will be higher if there are only small choices in the market. People tend to demand more for the product as they cannot find other product. TASK 2 *Definition of Price Elasticity of Demand (PEoD*) The price elasticity of demand is the measure of how responsive is the quantity demanded to a change in price. There are many types of elasticity in demand which will stand for different types of product in the market. In order to differentiate between them we need to state the definition and the ratio of the elasticity. Relatively Elastic Demand The relatively elastic demand is a demand relationship in which the percentage change in quantity demanded is large in absolute value than the percentage change in price. In other words the percentage change in quantity demanded is larger than the percentage change in price. {draw:frame} The ratio for the relatively elastic demand is 1< PEoD < Infinity Relatively Inelastic Demand The relatively inelastic demand is a demand that responds, somewhat, but not a great deal to change in price. In other words, the change in percentage change in price is larger than the percentage change in quantity demanded. {draw:frame} The ratio for the relatively inelastic demand is 0 < PEoD < 1 Unit Elastic Demand The unit elastic demand is a demand relationship in which the percentage change in quantity demanded is the same as the percentage in change of the price. {draw:frame} The ratio for the unit elastic demand is PEoD = 1 Perfectly Elastic Demand The perfectly elastic demand is a demand in which the quantity demanded drops to zero at the slightest in price. In other words, the quantity demanded will become zero if the seller increases the price of the product. While they will never reduce the price as it will reduce their normal profit. {draw:frame} The ratio for the perfectly elastic demand is PEoD = Infinity Perfectly Inelastic Demand The perfectly inelastic demand is a demand in which quantity demanded does not respond at all to the change in price. {draw:frame} The ratio for the perfectly inelastic demand is PEoD = 0 Calculating the Price Elasticity of Demand The formula to determine the price elasticity of demand is: PEoD = (% Change in Quantity Demanded)*/(*% Change in Price) Price (OLD) =9 Price (NEW) =10 Q Demand (OLD) =150 Q Demand (NEW) =110 Calculating the Percentage Change in Quantity Demanded [QDemand(NEW) – QDemand(OLD)] / QDemand(OLD) [110 – 150] / 150 = (-40/150) = -0. 2667 Calculating the Percentage Change in Price [Price(NEW) – Price(OLD)] / Price(OLD)] [10 – 9] / 9 = (1/9) = 0. 1111 PEoD = (% Change in Quantity Demanded)/(% Change in Price) PEoD = (-0. 2667)/(0. 1111) = -2. 4005 TASK 3 The product that I choose is tobacco. Both of the elasticity of demand and supply of tobacco is relatively inelastic. This is because the product will has an inelastic demand if the item is habit forming. As tobacco is a habit forming, it is relatively inelastic in demand. So if there is increase in price, the quantity demanded will not respond too much. While, the supply of the tobacco is relatively inelastic is because of the time period. As the tobacco is the agriculture product, it will take some times to grow it and get the product. So the producer cannot increase the quantity of supply although there are many demands for the tobacco. TASK 4 {draw:frame} The graph above has shown a market of tobacco with the relatively inelastic demand and supply curves. As we can see, the total surplus has reduced since the implementation of the tax. The benefit received by buyers in a market is measured by consumer surplus. The consumer surplus is the amount buyers are willingly to pay for the good minus the amount they actually pay for it. So the consumer surplus before the tax are (a + b + c). However, after the implementation of tax on the tobacco, the consumer surplus is only a. This means that the consumer needs to pay more after the implementation of tax. P in the graph stands for the price of tobacco before the tax. While, P*B* is the price that buyers need to pay after the tax has been implemented. The benefit received by sellers in a market is measured by producer surplus. The producer surplus is the amount of sellers received for the good minus their cost. So the producer surplus before the implementation of tax is (d + e + f). But, the producer surplus change after the implementation of tax, which became only f*. * This means that the seller received less profit after the tax implemented. **P*S in the graph is the price that seller received after the implementation of the tax. So this means that, the consumers and producers have to bear the tax burden after the tax has been implemented. Tax burden is the amount of tax suffered by individuals or organization. The tax burden for the consumer and seller may vary depends on the elasticity of the demand an d supply curves. Although the consumer and sellers seems to be burden by the tax, there is one party that gains benefit from it. It is the government because it has gain revenue from the tax. The tax revenue is the (b + d) in the graph above. From the revenue, the government can use it for other investment. However, the tax has also brought another disadvantage which is the deadweight loss. The deadweight loss is the reduction in total surplus that results from a tax. The deadweight loss in the graph is (c + e). The size of deadweight loss also depends on the elasticity of the demand and supply curves. If both of the curves become more elastic, then the size of the deadweight loss will become smaller. So in the conclusion the tax has given benefit to the government but brought disadvantages to the consumer and producer. REFERENCE LIST Mankiw, N. G. (2008). Ten Principles of Economics. In J. W.

Absence and Tardiness Military Tardiness Standard As a cadet, you are expected to be early (usually 15 minutes) for any military-related event. If you are going to be late let your flight commander or supervisor know ahead of time. Be professional; phone calls, e-mails, and text messages are appropriate however, remember to use your customs and courtesies at ALL TIMES! AFROTC Attendance Policy In AFROTC, 80% of your attendance is the minimum standard. As officers, we exceed the minimum. If you need to be excused for academic, work-related, family, or emergency reasons, you need to send an Absence Request Form (ARF) to your direct superior at least 48 hours prior to the scheduled event. In the case of failure to meet attendance minimums, disenrollment from the AFROTC program will be considered. II. Military Etiquette Conduct while in Uniform Never walk on the grass (unless for reveille or related ceremonies). Spitting, chewing tobacco or gum and smoking are not permitted in formation. Cadets should avoid these actions in uniform as they detract from professional appearance. When consuming food or beverage in uniform, do so in a professional manner.

Understanding Splinter Words in English Grammar

Understanding Splinter Words in English Grammar In  the branch of linguistics known as morphology, a splinter is defined as a fragment of a word used in the formation of new words. Examples of splinters include  -tarian  and -terian (from vegetarian, as in the coinages eggitarian,  fisheterian, and meatatarian)  and -holic (shopaholic, chocoholic, textaholic, foodaholic). The splinter is formally identical to a clipping, but whereas clippings function as full words, splinters do not (Concise Encyclopedia of Semantics, 2009). The morphological term splinter was  coined by linguist J.M. Berman in Contribution on Blending in  Zeitschrift fà ¼r Anglistik und Amerikanistik, 1961. Examples and Observations English has lots of splinters, among them tastic, as in funktastic or fishtastic, which is used to form mostly ironic words meaning excellent or great in reference to X, originally from fantastic, or licious, as in bagelicious or bootielicious, which is used to form words meaning appealing in reference to X, originally from the word delicious. The difference between a splinter and a true suffix is that speakers understand splinters  in relation to the original word from which the ending splits off. If these bits survive and continue to give rise to new forms, though, they might someday be real suffixes!(Rochelle Lieber,  Introducing Morphology, 2nd ed. Cambridge University Press, 2016)Blends, unlike regular compounds, are . . . based on analogy rather than on rules. For instance, the occurrence of the splinter -licious (from delicious) in beaulicious and bootylicious has attracted some new coinages: e.g. Girlicious (a musical lady trio), Kittylicious (referring to Hello Kitty mov ies), and Lehrers (2007) jocular blendalicious.(Elisa Mattiello, Extra-Grammatical Morphology in English: Abbreviations, Blends, Reduplicatives, and Related  Phenomena. Walter de Gruyter, 2013) What Happens to SplintersSplinters arise through the process of blending . . .. Thus, -nomics in Thatchernomics is a splinter, recurring in Reaganomics, Rogernomics, Nixonomics, etc.Splinters may have any one of three possible fates. They may disappear. I suspect that this is what has happened to -teria (a splinter from cafeteria which had a brief flourishing in words like washeteria but now seem to have become unavailable). They may become productive affixes. This appears to be what has happened with -nomics, cited above, although it is of very low productivity. They may become independent words. This is what has happened to burger, originally a reanalysis from hamburger which shows up in beefburger and cheeseburger.Since splinters may turn into affixes or words, we appear to have a situation where it is not clear whether new forms using the splinter will be derivatives or compounds. The -scape which emerged from landscape might be a case in point, though the Oxford English Dictiona ry lists so many instances of its being used independently that there can be little doubt as to its status as a word now. On the other hand, if we believe the Oxford English Dictionary, -cade (from cavalcade into motorcade) has become an affix.(Laurie Bauer, The Borderline Between Derivation and Compounding, in Morphology and Its Demarcations, ed. by Wolfgang U. Dressler. John Benjamins, 2005) Splinters in Blends[Blends] may be composed of two elements called splinters (ballute from balloon and parachute), or only one element is a splinter and the other element is a full word (escalift from escalator and lift, needcessity from need and necessity). . . . A special punning effect is achieved when one constituent echoes in some way the word or word-fragment it replaces, for example, foolosopher echoing philosopher, or fakesimile, echoing facsimile.(Pavol Ã…  tekauer, English Word-Formation: A History of Research, 1960-1995. Narr, 2000)

Luigi Russolos Dynamism of a Car Assignment Example | Topics and Well Written Essays - 750 words

Luigi Russolos Dynamism of a Car - Assignment Example The essay "Luigi Russolo’s Dynamism of a Car" explores the painting Dynamism of a Car by Luigi Russolo. The waves are supposed sound waves as the car moves against air. The concept of movement presented in the painting through sound waves is similar to an aspect known as the Doppler Effect graph. This is the use of repetitive lines to capture movement as seen in the painting. It can be stated that the dynamism of the automobile through movement captures the direction that the world is moving to as captured in 1912. The automobile is a powerful machine and shows an aspect of fast movement perhaps showing that the world is changing fast. The painting also shows richness in terms of color usage. Several colors including red, blue and yellow can be clearly seen in the painting. The red waves in this painting are beams of air resistance. It shows the resistance against the movement. Russolo put the red color towards the end of every wave line showing clear resistance to the waves m eaning that the car was in high speed. This is especially captured where the painting shows a thinning of the red color towards the apex of the waves and widen as the wave lines open up. The apex of the waves is the place where the car is. Therefore, where the red color widens shows that the force of the movement is great and that the air cannot resist it completely. Therefore, the air has to escape so that the car can move forward. At the front of the car, there is concentration of the red color meaning.

Essay on the poem The Nymphs Reply Example | Topics and Well Written Essays - 750 words

On the poem The Nymphs Reply - Essay Example Critical review of the poet tribulations in personal life, perhaps helps shade light on the biographical analysis of the poem. Raleigh life marriage life was controversial and later on in his pursuit for power. He wrote a poem at a time he had a secret marriage with Elizabeth Throckmorton, who was the royal court member in around 1592 (Muller and John 256). At the time of Queen Elizabeth, such marriage was not allowed and thus she ordered for execution of Raleigh. Many poets believe that it was through this reply that informed of his inner feelings and disillusion about love. He had been subjected to a forceful separation after the queen ordered the couple held at separate cells. Full of imagery, the poem represents a bitter feeling of isolation and solitude. Raleigh poem depicts his disappointment that love would be at its best at younger age. In the most intelligent manner, he was able to win the queens heart earlier in life, and he had loyal lucrative commissions. He used this time to reflect on the love, time and how life fades easily. However, the controversial marriage in 1592 made him jailed, and he wrote a reply poem. The life of this poet cannot be separated from the bibliographical analysis of his work. Argues that his poems reflected his personal experience and views on the place of love and time. Evidently, he uses imagery to display his disappointment during his love journey, his forced separation from a woman he ever loved and thus, finds it impossible to enjoy love after the rightful time (Lehman 21). In his reply poem he says " Soon break, soon wither soon forgotten," this line help demystify the historical disappointment and personal despair that informed the selection of words. Besides, he says "But could youth last, and love still breed" meaning, youthful age was the best to make love work to its best (Muller and John 257). At later years, he expresses doubts of the possibility of the shepherd finding his love
