Islamic Politics and Culture Essay Example | Topics and Well Written Essays - 1500 words - 1

Islamic Politics and Culture - Essay Example In fact Islamic dictatorship is prevailing in majority of the Arab countries. However, the recent revolutions in Libya and Egypt have forced many of the Arabs to think about a democratic political system in their country. However, the fundamentalists in those countries are against this idea. The concept of political Islam has been evolved out under the above context. According to Mohammed Ayoob, â€Å"Political Islam is a product of modernity as much as a response to it†(Rajesekhar). However, westerners are watching the dawn of Political Islam suspiciously. â€Å"In April 2014 Tony Blair urged the West to set aside its differences with Russia and China to focus on the growing threat from radical Islam† (Veerman). Westerners believe that Political Islamic movements are trying to destroy modernization and civilizations in the name of religion. This paper analyses the impact of the encounter between Western expansionism and Muslim-majority societies on the rise of politica l Islam. A crucial factor generating tensions in the West is the presence of ‘Islamism’ or ‘political Islam’, in all of its different manifestations, within Muslim communities. Islamism can be defined as "forms of political theory and practice that have as their goal the establishment of an Islamic political order in the sense of a state whose governmental principles, institutions and legal system derive directly from the shari’ah" (Veerman). The interference of religion in politics is unacceptable to westerners. They believe that religion should be separated from politics in order to create a stable and advanced society in a country. They have many examples to prove their arguments. For example, in countries such as Afghanistan and Saudi Arabia, women get less freedom and power in politics and social life. Westerners believe that the over involvement of religion in politics is the major reason behind these problems. They try to empower

World Views on theism Essay Example | Topics and Well Written Essays - 1500 words

World Views on theism - Essay Example Just as Hackett recounts, the absence of the divine Being immediately creates the limitations of cultural relativism. This is because, the notion that a divine Being exists and created the universe and the fullness thereof immediately gives room for moral absolutes or the universal law. Since a personal example suffices, living in America made me note that as globalization continues to render the US and the entire world a cultural melting pot because of multiculturalism, the danger of cultural relativism has certainly become inescapable. This danger has mainly manifested itself in a clash between legislative pieces and cultural values. For instance, because of the constant but radical shifting away from theism, the US government with all its constitutional maturity still remains ambivalent and unsure about the publication of literature such as Phillip R. Greaves II’s The Pedophile’s Guide to Love and Pleasure, despite the risks it poses to children. Only theism can here by strike this delicate balance between freedom of speech and conscience and that of children’s safety.... The crux of the mater herein is that when stimuli are introduced, there must be a response, as a corresponding action. Personally, I readily identify with behaviorism because I have come to note that results or consequences shape individual or collective action. Action in turn develops into behavior. Particularly, I have come to note that most of my colleagues did not take their assignments seriously until lecturers set deadlines. Reflecting on my past life also reinforce my belief in behaviorism, since we worked hard in high school, mainly upon knowing that entry into college or university learning would be based only on merit. Learning Styles Personally, kinesthetic approaches to learning have proven the best and most fruitful. This is because, this approach proves to be the most practical since it involves learning by performing, and therefore incorporates hands-on approaches such as movements, observing and other physical activities. Alongside note-taking and ensuring physical co mfort, joining study groups, using appropriate technology such as visual aids and reviewing information have catalyzed learning. The foregoing has especially been the case during encounters with cognitive sciences such as linguistics. Particularly, it has been virtually impossible to master phonetics, the International Phonetic Alphabet (IPA chart), the phonological processes and supra-segmental features thereof, without looking at the mirror to watch the movement of articulators, or feeling the movements of my articulators, or both. In courses pertaining to political science, history and sociology, I have found it most benefiting to my memory when I place the world map before me, as a reference material. Likewise, as one given over to kinesthetic approach, I have found

Medical Uses Of Infrared Photography Cultural Studies Essay

Medical Uses Of Infrared Photography Cultural Studies Essay Tattoos have been an invaluable method for the identification of non skeletonised remains. The design and/or location of the tattoo can be substantially exclusive to provide adequate identification, and especially when combined with other distinguishing features they can definitively identify and individual. During an autopsy the pathologist will take note of tattoos just as they would any other distinguishing marks, such as birth marks, defects or scars. In cases such as mass disasters, it can sometimes be one of only few methods available for the initial examination of the remains. In 2001, Kingsholm et al studied several unidentified bodies and remains found in Danish waters, some of which had tattoos. Discovery and detailing of any tattoos can also aid in tracing unidentified bodies back to their cultural backgrounds, thus in some cases tattoos have important historical aspects. Tattoos can also indicate a history of incarceration (Mallon et al 1999) and in such cases the individual sporting this unique design may not wish to be easily identified. Repeat offenders for example, may choose to remove or alter their defining features and members of gangs or organised crime groups may wish to no longer be associated with that particular faction. Some tattoos may serve to connect one individual with another, such as love tattoos, which can also aid in identification of the individual sporting the design. Different light sources and filter techniques have been used routinely in criminal investigations; the following uses of infrared (IR) photography presented in this introduction are all relevant to this study as they go some length towards explaining the nature of infrared and therefore what might be expected, allowing for deduction of a hypothesis which is presented later in this report. Infrared describes the part of the spectrum just beyond the visible red wavelengths (700 1200 nm) There are many used of infrared photography spanning many different fields. For art photography purposes, Infrared can be used to photograph objects in the distance, or in foggy conditions due to the infrareds ability to penetrate the haze (Milsom 2001). For portrait photography, infrared is sometimes favoured to give the appearance of a clear complexion Infrareds (IR) ability to penetrate the superficial layers of the epidermis of skin is exploited in medical photography as a method of photographing venous patterns underneath the skin and of documenting healing under lesions in the skin. They found that imaging in the near-infrared range provided relatively good contrast of subcutaneous veins. This works due to the fact that haemoglobin is a chromophore that absorbs near infrared, and the skin absorbs very little IR relative to the absorption of infrared demonstrated by the veins (Haxthausen, 1933), or transmits or reflects most of the near infrared spectrum, therefore it appears lighter by contrast to the darkened veins. Zharov et al (2004) identified the potential of this technique as a diagnostic method for varicose veins at a depth of 1-3mm into the skin. The use of infrared photography for the detection of varicose veins or any other subcutaneous abnormalities is demonstrated by Marshall (1981). This research uses infrared reflectance (as well as ultraviolet) to measure the densities across pigmented lesions of the skin and found it to be a useful method. The study by Haxthausen (1933) found that for documenting superficial afflictions, such as psoriasis, ordinary photography was far superior to infrared photography, as under the infrared conditions, the imperfections were removed. Afflictions that occurred in the deeper layers of the skin were captured best using infrared photography. In cases of burn injury is can be difficult to assess the damage or the thermal burn depth. Anselmo et al (1976) found that infrared photography could be used as a valuable and non invasive method of assess burn depth. Their experiment used Wratten 89A infrared filter Infrared photography allowed for the differentiation between viable and necrotic dermis. Infrared photography of bloodstains and Gunshot residue Forensic applications of infrared photography include detecting gunshot residue on clothing (Bailey et al 2007) and less commonly, for detecting bloodstains on dark clothing or at crime scenes. A report by Raymond and Hall in 1986 illustrated a dark coloured sofa, showcased in the report as a black and white photograph for the visual spectrum comparison. In this photograph there is no obvious bloodstain, it cannot be distinguished from the rest of the sofa due to the dark colour of the sofa. The infrared photograph was taken using the Wratten #88a filter. In this photograph the sofa had lightened and now by comparison, the area of bloodstained sofa (now darkened by contrast) could easily be distinguished. When using infrared photography to detect and document traces of blood on dark clothing, the infrared will make the blood appear darker and the surrounding clothing appear lighter by contrast. This is all due to the absorbing capabilities of the clothing and of the blood. Blood absorbs throughout the visible spectrum and the near infrared spectrum (typically absorbing most wavelengths of near infrared 700-900nm) and so its appearance in infrared records will be darkened, in contrast the clothing might only absorb through the visible light range of the spectrum, and so in the infrared records will appear lighter, or transparent. Dark clothing can hinder the successful visualisation of blood spatter patterns in much the same way that darkened mummified skin can hinder the detection of tattoos, or that charring on a fire damaged document can affect the successful visualisation of the writing. A study by Perkins (2005) used digital infrared photography, Wratten #89B filter to photograph blood spatter on several different materials. The dark clothing appeared to reflect the infrared, thus enhancing the contrast between the clothing and the blood patterns. Bailey et al (2007) used digital infrared photography to better visualise gunshot residue on dark clothing. It is very similar in both methodology and results to the use of this technique in bloodstain analysis. The camera ISO was set at 200 and the filter used was the Wratten #87. The GSR, undetected under visible light conditions, appeared dark against a lightened cloth under IR. The use of infrared in analysis of obliterated writings and questioned documents Infrared photography also has many applications in the field of forensic science. It is a common method for detecting obliterated writing (Creer 1976) for detecting forged, or altered documents, such as cheques and to aid in the examination of writing obscured by charring on fire damaged documents (Bartha. 1973) McCaul et al (2007) discuss the problems facing forensic scientists when traditional photography techniques fall short at documenting certain evidence. In the examination of documents, IR can be used to detect forgeries or alterations, relying on the fact that the visually similar inks may reflect or absorb infrared at varying levels and wavelengths. Parallels can be drawn between the uses of infrared for examining obliterated writing and this study into examining original tattoos from underneath cover tattoos. The use of correction fluid or other inks to cover writing serves to render the underlying text illegible, in the same way that the cover tattoo serves to distort, hide or completely cover the original underlying tattoo. If infrared photography can allow for the underlying writing to be visualised, than it is entirely possible that underlying original tattoo could be recovered. The successful recovery of obliterated writings is dependent on the different inks used and their infrared absorbing capabilities. Some ink, when irradiated with infrared, will absorb it. This is due to the presence of different Chromophores in the different inks (Ellen, 2006) A chromophore is the chemical group of a molecule that is responsible for the molecules colour, and they absorb, reflect and transmit different wavelengths. Other examples include chlorophyll, melanin and amethyst. Infrared photography can also be used to examine/restore writing on charred documents (Bartha 1973). The success of the visualisation is dependent on the degree of charring. The charred paper is darkened due to partly converted resinous material before being completely degraded to elementary carbon. The carbon in the pen ink absorbs the infrared and so appears dark under IR, by contrast the charred paper looks lighter. The Video Spectral Comparator (VSC) is often used in the examination of obliterated writing (G M Mokrzycki 1999). The VSC uses Infrared radiant energy and filters to see through inks and other obliterations, and reveal obscured objects. The use of infrared photography is not an uncommon method for visualising and recording obliterated writing, S. Sugawara (2004) discusses the use of both near and middle infrared in deciphering obliterated writings by looking at writing made by 101 different pens. Erasures describe inks that have been made invisible by removal of the colour components of the inks. Sometimes when these components are removed, remnants are left behind. Sometimes whatever remains on, or just below, the surface can be detected using infrared. This is the same principle encountered in a paper by McKechnie et al (2008) in which infrared was used to detect remnants of ink left behind in the skin post-laser removal treatment. The findings of this research will be analysed in greater detail later on in this research paper. Other uses of infrared photography The uses of Infrared photography do not begin and end at medical and forensic uses however, for example, Bridgeman and Gibson (1963) used infrared to examine paintings. A paper by J R J Van Aperen De Boer (1969) successfully applies Infrared Reflectography to view the under-drawings of carbon pencil, with varying degrees of success of medieval paintings. Pencil lead (which is primarily graphite) absorbs throughout the infrared range of the spectrum, and the visible range. Because of this, under both near and far infrared conditions the graphite will remain as readily viewable as to the naked eye. Thus far this project has looked at both medical and forensic uses of infrared photography, many of which have in common the idea that infrared can be used to recover, or detect traces of one material (for example; ink) from underneath another material (such as correction fluid). These underlying or otherwise camouflaged materials are not readily viewable with the naked eye, or easily recorded using ordinary photographic methods. This is the same principle as is to be employed in this research. The detection of latent residue tattoo ink pigments The use of infrared photography to record tattoos is by no means a recent phenomenon. As long ago as 1938 JÃ ¶rg used infrared photography to detect tattoos that were otherwise undetectable with the naked eye. Although infrared photography has been utilized to study tattoos, there is not a great deal of literature available on the topic. Below some specific examples are given. The following are 2 examples found provide useful validation of infrared penetrating capabilities coupled with its specific use for detecting tattoo designs that have been affected by environmental conditions, or purposefully made difficult to visualise: Mckechnie et al use infrared photography to attempt to visualise latent tattoo ink residue from laser removed tattoos. This research article only used 2 participants, and with a success rate of 50% and so a follow up experiment would be required using a larger sample size to validate the findings. Both participants had their tattoos removed by laser treatment to the extent that they were no longer visible to the naked human eye. One of the participants tattoos was professionally done; the other was an amateur tattoo. Although the authors explain the difference between amateur and professional tattoos as a possible factor (that is that professional tattoos use more ink and are injected deeper into the dermis than amateur tattoos) and cross reference it with infrareds ability to penetrate the skin, they do not expand on the colour or pigment as being factors resulting in the success or failure of the trial. Visualising tattoos on mummified remains using infrared photography One of the original journal articles of interest that could be said to have initiated the thought behind this project idea, or at the very least inspire a belief of the success of the project, uses infrared Reflectography to examine tattoos on mummified remains, the mummified tissue normally being darkened to the extent that visualisation under normal photography conditions is near impossible (Alvrus et al 2001) It showcases the usefulness of infrared for lightening certain aspects of a subject in order to see others. In this case, the darkened mummified tissue made it difficult to visualise the tattoo under normal photographic conditions (visible light). Under Infrared conditions however, the contrast between the tattoo and the surrounding skin was enhanced; the darkened mummified skin appeared lighter, and by contrast the tattoo (which appeared darker) was readily visible. This is due to the differing absorption/reflection of infrared. The substances in the tattoo absorb the majori ty of the infrared; the surrounding skin reflects the infrared. A similar technique is used in the identification of tattooing on a 1600 year old mummified body found in Alaska (Smith and Zimmerman 1975) Tattooing was identified on the hands and forearms of the Eskimo female remains using infrared photography. The darkened skin obscured the tattoos to the extent that they could not be viewed under visible light spectral range photography. Skin thickness as a factor One of the other variables accounted for in this project is the area on the body of that tattoo, the thought behind this being that the thickness of the skin might come into play. According to E J Wood (1985) the thickness of the epidermis ranges from 0.06 0.1mm (from eyelids, to back and callused areas, respectively). The dermis ranges from 2 4mm thick, and accounts for the bulk of the skin. Although any differences in skin depth tend to be minute, they may still account for variable success rates due to the migrating nature of tattoo ink through the dermis and the penetrating capabilities of infrared. A skilled tattooist will not allow the needle to penetrate the skin no deeper than 2mm, the reasons for which are discussed below in The tattoo process. The ink must be deposited deeper than the epidermis, or else the ink will fade as the outer layers of the skin shed, therefore the thickness of the epidermis will affect how deep the ink must be deposited. It is also assumed that th e thickness of the dermis will correlate with the thickness of the epidermis. This is why this research paper has chosen to look at the area on the body of the tattoo as a possible factor. The tattoo process The process of tattooing involves injecting pigment, suspended in a carrier, through the epidermis and into the dermis of the skin, no more than 2mm or else the tattooist risk the ink bleeding, creating a smudged effect, regardless of the tattoo technique employed (the settings of the modern tattoo machine do not allow for the needle to penetrate any deeper than 2mm). There is no exact science as to the pressure exerted on the needle by the individual tattooist, as it is a matter of personal judgement (direct quotation from Mark tattooist from Dannys tattoo Studio in Sneinton, Nottingham) depending on the area of the body on which the tattoo is being performed. Tattooing on an individuals back or upper arm will require greater pressure because the skin is much thicker, the setting of the tattoo machine will also have to be altered for deeper penetration through the epidermis and into the dermis. Once injected into the upper layer of the dermis, the pigment is suspended in the fibroblasts (Sperry 1991). When looking at a tattoo, the tattoo is being viewed through the epidermis. Over time the deposited tattoo ink will disperse deeper into the dermis, and so it is possible that time, both between original and cover, and time since cover, could be a feature in the investigation. Tattoo Ink pigments More often than not, the tattooist will use a tattoo ink containing pigments which will be manufactured outside of the tattooists own premises, the exact content and purity of which is in most cases, unknown. There are certain guidelines in place for manufacturers of tattoo inks to abide by when producing the inks, however manufacturers of tattoo ink are not forced by law to disclose the ingredients used in the inks. A study by Timko et al (2001) found that, of 30 inks studied, the most commonly identified elements were aluminium, oxygen, titanium and carbon at 87, 73, and 67 percent respectively. Professional tattoo artists have access to over 100 different colours (Kirby et al 2005), many of these are mixtures of colours, for example red and white to make pink, thus making it difficult to classify pigment-wise. The research by Kirby et al (2005) found significant variability in pigment cluster sizes in professional tattoos, compared to amateur tattoos. They also found colour pigment granules to be larger than black pigment granules. This was initially an area of interest, but not one that this research paper will focus on due to the difficulty encountered in obtaining the relevant information. This study uses infrared photography in an attempt to visualise an original tattoo from underneath a cover tattoo, the success of which could be due to a number of different factors. A summary of these factors are as follows: To look at the colours used in both the original tattoo and the cover tattoo and how this affects the successful visualization of the original tattoo using infrared. To look for any correlation linking time since cover tattoo (up to date of photograph) and success of the experiment. This essentially will be looking at the effects of the migration of tattoo ink. To look at any trends involving time elapsed between original tattoo and cover tattoo, and the success of the infrared photographs obtained. As above, this will be examining the effects of ink particle migration. To look at the area on the body of the tattoo and discover if there is a relationship between this and the success of a particular photograph. Essentially, this is investigation skin density as a factor. Taking into account all the research discussed previously and the results obtained by the various studies in the field of infrared photography a few hypotheses have been deduced: The first is that the penetrative nature of infrared suggests it is possible to recover the underlying pigment of the original tattoo from beneath the cover tattoo. The reasons behind this are thought at this stage to be due to the colours present, or perhaps even the concentration of black used in the colour mixtures. The way in which an object appears when photographed using infrared is a direct consequence of their absorbing capabilities. For the purposes of this particular study inspiration was drawn for the research into questioned documents, or more specifically the detection of different inks using infrared. Most inks have different absorbing capabilities, some will only absorb through the visible light spectrum, and some throughout the visible light and into the infrared range. The reason behind this, as mentioned earlier, is due to the chromophores in the dye molecules. In the same way that infrared might be used to detect the underwritings of obliterated text, IR could be used to detect the underlying tattoo pigment, depending on the chromophores, or colours used. The second hypothesis is that any variation in the depth/thickness of the skin will be such a minute difference that it is unlikely to affect the overall success of the project. The factors of time (time between original and cover, and time since cover) are likely to have minimal effect, if any, on the successful visual recovery of the underlying tattoo. It is thought that any trends are more likely to be observed in the extreme time periods, for example, between tattoos that are under a year old and tattoos that are over 30 years old. This is because the most recently done tattoos will not have been affected by migration, whereas very aged tattoos will have undergone decades of migration of the ink particles. Method and materials A sample number of 33 (n33) individuals were used in this research, all of whom volunteered their time and consented for the presentation of their tattoos anonymously in this research paper. All that was required of potential participants was that they had a cover tattoo, there was no other criteria selected for, for example age or gender. The participants were then required to fill out a consent form, as no photographs could be taken without. The participants were asked to fill out a short questionnaire to aid in investigation of the various factors discussed in the introduction, an example of which can be found in the appendix. This project utilizes the near infrared part of the spectrum (the far infrared part of the spectrum is commonly used for thermal imaging). The infrared filters allow infrared light to pass through the camera and blocks most of the visible light spectrum. The Fujifilm IS pro digital SLR camera is sensitive to both ultraviolet and infrared light between 380nm and 1000nm. Optimum settings for the camera were assessed during several pre-experiments. Manual setting, ISO 200 and aperture f/6.3, which provided adequate depth of field for the infrared photographs Filters 87 and 88a were used, which are described as deep infrared filters; allow no visible light to pass through. The Wratten 87 filter has a sharp cut-off at ~800nm, and so transmits freely throughout the infrared region. The 88A has a slightly narrower window with an effective cut-off at ~750nm. The control photographs were taken using a UV/IR barrier filter. All photographs are taken at a 90Â ° angle from the subject (as close to as possible without actually measuring the exact angle) this was to eliminate any false positives due to raised tattoos (which can happen in hot conditions). A colour scale, a grey scale and a sizing scale are held in place around the tattoo. The first photo taken is the control photograph, using the IR-UV cut lens. This allows visible light to be captured and so essentially, is just a normal (visible light) flash photography picture. The second photograph removes the UV-IR cut lens, replacing it with an IR filter. The first used is the Wratten 87, as many photographs as necessary are then taken using this filter. The third set of photographs is taken with the 88a IR filter. The Metz 45CL4 electronic flash gun was the light meter of choice, the setting of which differs between photos depending on the light source available at the location. A number of photographs were taken of each tattoo; one control photograph, and 2 photographs using each filter. The first infrared photograph was to capture the entire tattoo, including the scales. A second photograph was taken if deemed necessary, which was a close up shot, focussing on any areas of interest highlighted in the first infrared photograph in order to capture better detail. Once all of the photograph records were obtained they were categorized into successful and unsuccessful. Of the successful results, due to the varying degrees of success encountered from record to record, it was felt necessary to categorize further still with the introduction of a grading system. The grading system is as follows: 0 None of the original tattoo could be visualised 1 Partial original tattoo visualisation 2 Most of original tattoo can be seen 3 All of the original tattoo can be seen from underneath the cover tattoo. Please note that some of the images presented in this report have only undergone basic alterations post production. The changes made to the infrared images were limited to minor brightness and contrast changes to accentuate any detail in the pictures that may have been lost when the images were resized and in order to retain detail in the printed hard copy. These changes are as follows: Brightness was altered to a maximum of around -10% for the infrared images on Microsoft Office Word 2007. Contrast was altered to a maximum of +30% on Microsoft Office Word 2007. These values are approximate, and dependant on the detail captured in the original, unaltered photographs. The images were not altered in any other way The underlying tattoo can be somewhat visualised under visible light photography conditions however visualisation of the original tattoo is accentuated using the Infrared as it removes the camouflage or interference provided by purple shading of the cover tattoo. This is a grade 2 example. This was graded as 2 because a substantial amount of the original tattoo can be recovered. In this case, the tattoo, under visible light conditions, is not an obvious cover tattoo as no detail of the underlying tattoo can be detected due to the use of shading and the faded nature of the original tattoo. With the shading of the cover tattoo removed using the IR filters the detail in the original tattoo can be visualised. The black shading of the cover tattoo on the eagles head and wings is not visually removed by the infrared, and so part of the cover tattoo is still camouflaged. Note The dark green and blue of the original tattoo appear darker in the infrared than the other colours of the cover tattoo. The purple in the background has completely disappeared in the infrared photograph. This is a particularly interesting record as it demonstrates the absorbing capabilities of black ink. Although some of the original design can been seen in the control photograph it is somewhat polluted by the dark colours of the cover tattoo. The blue and particularly by the purple of the cover design are visually removed in the infrared photograph, highlighting the contrast and allowing for better determination of the actual design. It would be expected that if there were a trend amongst these results that as the time since the cover tattoo increases, so would either the success or failure rate. At the same time, the remaining (factor either success or failure) would decrease as the other increases to show that there is a clear correlation. This does not occur, and so suggests that there is no link between time since the cover tattoo, and the overall success rate. Also there does not appear to be any detectable trend in the observed graph patterns between fig. 9 and fig.10 A summary table of records, including information on colours used, the grade allocated to each record, and a brief description of what can be seen with each record, is available in the appendices (Appendix 4) the findings of which are discussed in the discussion section of this research paper It should be noted that this graph only presents the number of cover tattoos with black ink in the design and does not take into account whether or not the black ink is directly responsible for the obscuring of the original tattoo design. It does, however, present a slight trend, which is to be expected. In cases where the cover tattoo is colourful, the Wratten 87 filter appeared to be the filter of choice as it removed all colour of the cover design to reveal the underlying original tattoo. In cases where the cover tattoo consisted of cut black or grey shading, the Wratten 88a appeared to be the ideal filter to better accentuate the original design from the cover tattoo design traffic. Of the unsuccessful examples: The following results are characterised according to the observed reason why the original tattoo could not be visualised. Please note that in 100% of the unsuccessful records the cover tattoo design contained black ink, however in some cases it is not deemed to be the reason for unsuccessful visualisation (In some cases for example, the black of the cover does not cover the original design) Discussion This research has proved definitively that infrared photography can be employed to detect an original tattoo design from underneath a cover tattoo. Of the several factors investigated in this paper that were thought to affect the success of the recovery of the original tattoo using the IR filters, the only factor with any real merit were the colours used in the original and cover tattoos. The time since the cover tattoo was investigated due to the behaviour of the ink once deposited in the skin. As explained in the tattoo process section, once the ink is deposited, over time some of the particles will disperse throughout the dermis. It was thought that the effect of this, if any, would be to hinder any successful recovery of the underlying tattoo. No obvious correlation was discovered between the time since the cover tattoo and the successful recovery of the original tattoo from underneath the cover tattoo. Time between original tattoo and cover tattoo also yielded no apparent association to the success rate. The graphs and a brief description of the findings can be seen in the results section of this paper (fig. 18 and Fig. 19) When looking at the area on the body as a factor (essentially that is looking at the depth or thickness of the skin) it seemed necessary to take two examples from areas of differing skin thickness and compare the success rates from each. The skin thickness of the wrist will be significantly less than the thickness of the skin on the back, which along with the soles of the hands and feet, is one of the areas on the body of the largest skin density. Of the results for the wrist tattoo, 50% were successful. This was the same as with the results from the examples photographed on the back (Fig.17) suggests that the area on the body of the tattoo had little or no bearing on the results. As predicted it is the colours used in both the original underlying tattoo, and the cover tattoo, that has the most bearing on the successful visualisation of the original tattoo. Visualisation of the underlying tattoo was most striking and effective with the examples with purple, red, light blue and white cover tattoos this is likely to be due to the different chromophores (the functional group of the pigment molecule that gives it its colour) in the different colours used, as they will absorb or reflect the infrared wavelengths at varying levels. Red and purple cover designs yielded the best results because these colours were completely visually removed by the infrared filters, leaving only the underlying original tattoo visible. Referring to Fig.1 and 2 of record 26, the purple of the cover design is completely visually removed under the infrared photographic conditions, allowing the black outline of the original underlying tattoo to be completely visualised. Records 22, 26 and 26b are perhaps the best examples, each receiving grade 3 in the grading system for complete visualisation of the original tattoos. The original designs can be easily distinguished as there is no interference from any fragm

Henry V and Picard :: Star Trek Essays Papers

Henry V and Picard "The Defector" is the 38th episode from Star Trek the Next Generation's third season. This episode is received well by many ST TNG fans. The episode deals with several interesting and conflicting issues such as a traitor / defector, innate human qualities and a Shakespearean type leader. The most intriguing personality on the episode is Jean Luc Picard, the great captain. Picard has many similarities to Henry V, they both probe into every conflict and always prove to be a strong and capable leaders. They are both of strong character, conscientious, objective and intuitive. The story requires the captain utilize his outstanding qualities to decide if the exiled Romulan on his ship is trustworthy. If Picard believes Jaroc, it would mean going into the neutral zone and destroying a base in order to prevent a war. However, if Jaroc is lying this course of action will make Picard the instigator of a futile war. In the same way, if Henry's cause is unjust, the guilt and blame will lay on his head(Fisher 51). One of Picard's greatest qualities is his objectiveness. When Jaroc refuses to disclose any information, Picard diligently explores all his options. He decides to send a probe in order to reach the truth. Later, Jaroc attempts to prove his sincerity by revealing his identity. He discloses the emotional reasons for his presence aboard the Enterprise. Picard is not affected by Jaroc. By reason of his intuition, Picard continues to demand "irrefutable evidence" because he will not risk the welfare of the crew. Not only is he concerned about the welfare of the crew as a whole, but also on an individual level. In the opening to the episode, Picard attempts to aid Data in furthering his understanding of human behavior. Upon Data's request for advice, he suggests Shakespeare. Data plays the role of King when he performs the first scene of Act IV from Henry V(Peterson). In this scene, Henry disguises himself and mingles with his troops to share their ultimate fears on the eve before battle. "They have a discussion of leading one's men to die"(Lynch). Ironically, Picard directs the scene which parallels his position through the story. The fact that Henry V is one of Shakespeare's histories is very significant because history is the backbone of the episode. References to their history with Romulans are made. Such as to events on Galornden Core, in which Beverly the doctor explains that she recently gained a lot of experience with Romulan physiology.

Relationships Between Humans & Plants& Animals Essay

Humans, animals and plants have a great relationship with each other, they need each other, and they make each other’s lives better. Without plants and animals, human won’t be able to survive or can not live till now because humans need plants and animals to feed themselves. On the other hand, plants aren’t able to grow, too because they need to be taken care by humans. Therefore, human should protect both animals and plants. But human couldn’t take good care of animals, most of the animals in the forests are extinct because of human acts, they kill those animals carelessly for their own needs. Although, humans also do animal science to help them from terrible sickness and their strange behavior. In our time, we are smart compared to ancient people. At first, humans don’t know how to fly. But then humans get smarter and smarter and they started to associate themselves with new knowledge, educate animal and analyze chemicals and animal’s tissue. Then they learned how to make airplanes by using birds’ shape. In other words, humans also need animals to study about them and use them to improve their technology. Humans also use animals for their agricultural setting, animals’ wastes are also important for plants; they use those wastes as natural fertilizer in agriculture, more than that, animals help us to protect our home, we also use animals for other things like using their skin as clothes or purses, eating them, killing them for their paws, claws, tails, cutting off their head and use them as home decorations, illegal hunting and more surprisingly some humans just kill animals for fun. Because of our careless acts, more and more animal species are e xtinct. Hundreds of thousand years ago, ancient people didn’t know how to make medicine, so many of them died because of diseases. But later on, humans started to learn that they can use plants as medicine, they use their roots, leaves, branches and more. Humans first learnt how to float on water by using boats that are made from woods. Almost every part of a plant is important to both humans and animals. We also eat plants which have been categorized in to crops, fruits, seeds, and vegetables, and we use plants to feed our livestock, too. For example, cows eat grass, chickens eat grain†¦etc. Humans also cut down trees and use those fine woods to make wooden furniture and houses. Plants also help to take in carbon dioxide which we might get carbon dioxide poisoning or carbon dioxide intoxication by breathing it too much, and more importantly they produce oxygen which both animals and humans use for breathing. At the very beginning of Earth, Earth’s atmosphere contained only carbon dioxide, nitrogen and other gases. But it almost contained no oxygen. Some time later, plants started to grow on Earth and they produce oxygen until then there were lives on Earth. Plants attract rain and help us to protect our planet from the sun. So, plants play a very important role in our and animals’ lives. As we all have known how plants, animals and humans are important to each other. In my opinion, we should all care more about those plants and animals, we should all take the responsibilities to protect those animals from extinction and plant more trees to protect our world and for our benefits,

Huck Finn Comparison Essay

Justin Esteves 1/18/12 Puddn’head Wilson and The Adventures of Huckleberry Finn Comparison Essay There are several differences that are evident between Puddn’head Wilson and The Adventures of Huckleberry Finn. One of the major differences between the two books is the characters that are involved in the stories. They have different personalities and react differently to different situations.The twins in Puddn’head Wilson are young men from noble descent from Italy who left their country. They are smooth talking, but really don’t lie about a situation. However the Duke and King in Huckleberry Finn aim to trick people in different towns by selling the people tickets to a show that never existed. In one instance a man dies and they pretend to be related to him so they can get his inheritance. The ages of the main characters are different as Huck is a boy while the characters in the other story are adults.In Puddn’head Wilson it is said not to have a spe cific plot line, but in Huck Finn the story follows the classic plot line scheme. There are many similarities between the two stories. One of them is that the settings are very much the same as they both take place on the Mississippi River. Actually when I was reading Huck Finn, I couldn’t get the picture of the setting of Puddn’head out of my head. Another similarity is that the twins and the King and Duke are similar characters since they are together in pairs all the time in the book.The final similarity is the involvement of death in both books. The whole story of Puddn’head is based around a murder. In Huck Finn, Huck makes it look like he was killed to escape from Pap and the town. After Mr. Wilks’ death, the Duke and the King go after the money in his will. Another death in Huck Finn was Pap who was found dead in a house during a flood. Overall The Adventures of Huckleberry Finn is a lot better than Puddn’head Wilson.After reading several re views more readers liked Huck Finn and some people really disliked Puddn’head Wilson. Both books were about life on the Mississippi River from a long time ago. It was interesting to see how people lived in that period of time. Even though the stories took place many years ago, there are many similarities between the people from then to now as to how they treat each other. People were the same then as they are now and have the same outlook on life. The books and life follow Mark Twain’s quote, â€Å"The damned human race. †

Analysis of Wilfred Owens The Last Laugh Essays

Analysis of Wilfred Owens The Last Laugh Essays Analysis of Wilfred Owens The Last Laugh Paper Analysis of Wilfred Owens The Last Laugh Paper Essay Topic: Poetry Wilfred Owen is well known for his portrayed war poetry on the trench and gas warfare. Owen wrote many poems during his lifetime and one of them is called ‘The Last Laugh’. ‘The Last Laugh’ is very short but incredibly effective because it’s from the weapon’s perspective and from his first hand experiences of war. The main idea Wilfred Owen wanted to convey was that it’s not the soldier’s who get the last laugh since many people died and many soldiers would not laugh about it. He shows that the machinery of the war is the master of the soldiers and that the weapons had the last laugh. In this essay I will talk about how Wilfred Owen conveys his feelings on war by his use of imagery, his choice of language, the structure of the poem and the voice and tone of the poem. First of all, Owen creates images that really convey his experiences of WW1. The poem starts off with a solider that shouts â€Å"Oh! Jesus Christ! I’m hit. † This solider is either just swearing because he was hit or he could have actually been crying out to God because he is religious. In the last stanza Owen shows an image of a solider who â€Å"slowly lowered, his whole face kissed the mud. You can really picture an image of a solider that just got shot and is about to die and the last thing he thinks of is his loved one. You can imagine him closing his eyes and thinking of her and just imagining that he is with her and kisses her, when he is actually kissing the mud. The soldier is not described at all only his actions are described. The lack of details of the soldier shows that he doesnt need any details because the reader already knows how the soldier is, a young man who just wants the war to end. Owen also uses personification to describe the weapons and make them look like they are alive by giving each weapon a capital letter just like they have names like humans. The weapons are also given physical features that a human would usually have. For example, the Bayonets have â€Å"teeth. † The bayonet has a human feature, which is teeth but not just normal teeth, â€Å"long teeth,† which makes the bayonets look like beasts. The weapons are very descriptive with detail and the soldiers are lacked in description and this shows how the weapons are dominant and that there were so many soldiers that died that there is no need for them to be described. Not only are the weapons personified like humans but also the bullets are personified. Owen used personification by giving the bullets voices. â€Å"The Bullets chirped,† This shows that the weapons have taken over of the war. Owen uses a metaphor when he compares the shrapnel from an exploding bomb to a cloud. This metaphor helps the reader use his or her imagination. In the poem ‘The Last Laugh, imagery was used to really convey Owens thoughts on WW1. Secondly, Owen’s choice of language conveys his experiences of WW1. Owen uses an interesting word to describe the bullets in the first stanza; he uses the word â€Å"chirped. † This makes it seem like the bullets are like flying birds, because it is the noise that birds make. Also you can imagine the bullets like birds flying freely through the air. On the other hand, the men have no freedom whereas the weapons do. Owen repeats the word â€Å"vain,† and this emphasizes that whatever the soldiers try to do and defend themselves, no matter what they try it won’t work. Another word that Owen repeats is the onomatopoeic â€Å"tut-tut. This makes it sound like the machine guns are telling off the soldiers, like a parent would to their son when they do something wrong. The weapons are telling off the soldiers for them trying to stay alive in front of them and they have no match for the weapons. The weapons are mocking the soldiers throughout the poem. In the line â€Å"The Big Gun guffawed,† the word â€Å"guffawed,† shows that the gun is mocking the soldiers and cannot stop laughing. As well, it is very weird to smile just before you die. However in the second stanza, the soldier â€Å"smiled. The soldier was probably described as smiling because maybe he was happy that he was dying due to the fact he was fed up with the war. This description of a dying soldier smiling before he dies confuses the reader and makes the reader think why is the soldier smiling. There were many young soldiers fighting for their country and Owen tells us by using the word â€Å"childlike. † Also, the soldier in the second stanza was crying out for his mother and father, tells us the soldier is young and all he wants his mother and father like a normal young kid would want and have when young. In most of his poems, he always refers to how young some of the soldiers were because he probably thought it was crazy how young the some of the soldiers were. The young soldiers didnt have a normal childhood like kids do today. A word that makes it look like the Shrapnel-cloud is a human is the description that it â€Å"leisurely gestured. † It suggests that the Shrapnel-cloud has arms because he is gesturing in a very relaxed way, just like a human would. The word â€Å"leisurely’ stands out because you think why would a cloud gesture something in an unhurried manor. The weapons were not only personified as humans but also as animals; we see this in the last sentence of the last stanza with â€Å"The Gas hissed,† where the onomatopoeic ‘hissed’, makes the gas sound like a snake. Gas makes a hissing sound and snakes hiss makes the gas sound like an evil weapon. Owens choice of language shows his attitude to WW1 and shows what he thinks about it. Thirdly, Owen’s choice of structure in the poem is very unique and conveys his experiences of WW1. Each stanza is five lines long and the first two lines of each stanza are about humans and the last three are the weapons response to the humans. The weapons have more to say then the humans and it makes it look like the weapons are the masters of the soldiers and are superior. Owen doesnt give an identity to the humans but he gives an identity to each weapon by giving it a capital. For the humans, Owen uses pronouns. There is also a very abrupt death to each soldier. â€Å"I’m hit, he said: and died. † It doesnt describe how he died; he just died like many other soldiers did. Also Owen makes it look like the deaths of the soldiers don’t really matter. â€Å"Whether he vainly cursed, or prayed indeed. It doesnt matter if he cursed or if he was praying, he still died. Owen also makes the three soldiers described in the poem are just fed up with the war, by using words like â€Å"said,† â€Å"sighed,† and â€Å"moaned. † These words described how the soldiers are speaking and they all sound like they are happy that they are dying because they are fed up with the war. The first soldier is crying out to God or cursing. The second soldier is crying out for his mother and father and the last one is thinking of his loved one. After each soldier speaks, there are weapons mocking the soldier that just died. The shortest line of the poem is the very last line, â€Å"and the Gas hissed. † World War 1 was when gas warfare was first used on a large scale. The gas is the thing that haunts Owen most and it is the last weapon he describes since its the weapon that he will remember for the rest of his life. Owen conveys his experiences of WW1 by choosing a certain structure of the poem. Fourthly, Owen conveys his experiences of WW1 by the voice and tone used in the poem. The last laugh sort of has a fun tone of voice to it. It is consistent throughout most of the poem until the last line, where it had more of a serious tone. I think this was done because gas was a very serious topic for Owen and he doesnt want to make it sound like it wasnt serious. There are different tones of voices for each weapon that speaks. For example, the Shrapnel-cloud has a very deep voice since its a massive big cloud so you can just imagine a deep tone of voice linked to the cloud. The language is more colloquial to formal because the poem has a fun tone of voice to it. Owen uses irony in the poem because the title â€Å"The last laugh† can be thought of as the last ones alive. The weapons were all in one piece and were unharmed, whereas the soldiers died. It’s also ironic because he says that the weapons had the last laugh however the weapons can’t even laugh. Owen expresses his feelings of WW1 by the tone and voice used in the poem. In conclusion, I think that Owens poem ‘The Last Laugh’ is a great poem and he was very successful at expressing how he feels about World War 1. The poem was effective in conveying Owens feelings because of all the techniques used in the poem. I would never think about the weapons having the last laugh, it would be the last thing I would think of. It was a very smart poem, how he personified the weapons to make them like humans. Every single thing was well thought of and I love how the humans have two lines and the weapons have three lines and how they respond to the humans. The last line also made me really think of gas and how it caused many harsh and painful deaths that I cannot even imagine. Overall, the poem was a great poem because it really conveyed Wilfred Owens experiences of WW1 by his use of imagery, choice of language, the structure of the poem and the voice and tone of the poem.

A List of Radioactive Elements

A List of Radioactive Elements This is a list or table of elements that are radioactive. Keep in mind, all elements can have radioactive isotopes. If enough neutrons are added to an atom, it becomes unstable and decays. A good example of this is tritium, a radioactive isotope of hydrogen naturally present at extremely low levels. This table contains the elements that have no stable isotopes. Each element is followed by the most stable known isotope and its half-life. Note increasing atomic number doesnt necessarily make an atom more unstable. Scientists predict there may be islands of stability in the periodic table, where superheavy transuranium elements may be more stable (although still radioactive) than some lighter elements.This list is sorted by increasing atomic number. Radioactive Elements Element Most Stable Isotope Half-lifeof Most Stable Istope Technetium Tc-91 4.21 x 106 years Promethium Pm-145 17.4 years Polonium Po-209 102 years Astatine At-210 8.1 hours Radon Rn-222 3.82 days Francium Fr-223 22 minutes Radium Ra-226 1600 years Actinium Ac-227 21.77 years Thorium Th-229 7.54 x 104 years Protactinium Pa-231 3.28 x 104 years Uranium U-236 2.34 x 107 years Neptunium Np-237 2.14 x 106 years Plutonium Pu-244 8.00 x 107 years Americium Am-243 7370 years Curium Cm-247 1.56 x 107 years Berkelium Bk-247 1380 years Californium Cf-251 898 years Einsteinium Es-252 471.7 days Fermium Fm-257 100.5 days Mendelevium Md-258 51.5 days Nobelium No-259 58 minutes Lawrencium Lr-262 4 hours Rutherfordium Rf-265 13 hours Dubnium Db-268 32 hours Seaborgium Sg-271 2.4 minutes Bohrium Bh-267 17 seconds Hassium Hs-269 9.7 seconds Meitnerium Mt-276 0.72 seconds Darmstadtium Ds-281 11.1 seconds Roentgenium Rg-281 26 seconds Copernicium Cn-285 29 seconds Nihonium Nh-284 0.48 seconds Flerovium Fl-289 2.65 seconds Moscovium Mc-289 87 milliseconds Livermorium Lv-293 61 milliseconds Tennessine Unknown Oganesson Og-294 1.8 milliseconds Where Do Radionuclides Come From? Radioactive elements form naturally, as a result of nuclear fission, and via intentional synthesis in nuclear reactors or particle accelerators. Natural Natural radioisotopes may remain from nucleosynthesis in stars and supernova explosions. Typically these primordial radioisotopes have half-lives so long they are stable for all practical purposes, but when they decay they form what are called secondary radionuclides. For example, primordial isotopes thorium-232, uranium-238, and uranium-235 can decay to form secondary radionuclides of radium and polonium. Carbon-14 is an example of a cosmogenic isotope. This radioactive element is continually formed in the atmosphere due to cosmic radiation. Nuclear Fission Nuclear fission from nuclear power plants and thermonuclear weapons produces radioactive isotopes called fission products. In addition, irradiation of surrounding structures and the nuclear fuel produces isotopes called activation products. A wide range of radioactive elements may result, which is part of why nuclear fallout and nuclear waste are so difficult to deal with. Synthetic The latest element on the periodic table have not been found in nature. These radioactive elements are produced in nuclear reactors and accelerators. There are different strategies used to form new elements. Sometimes elements are placed within a nuclear reactor, where the neutrons from the reaction react with the specimen to form desired products. Iridium-192 is an example of a radioisotope prepared in this manner. In other cases, particle accelerators bombard a target with energetic particles. An example of a radionuclide produced in an accelerator is fluorine-18. Sometimes a specific isotope is prepared in order to gather its decay product. For example, molybdenum-99 is used to produce technetium-99m. Commercially Available Radionuclides Sometimes the longest-lived half-life of a radionuclide is not the most useful or affordable. Certain common isotopes are available even to the general public in small quantities in most countries. Others on this list are available by regulation to professionals in industry, medicine, and science: Gamma Emitters Barium-133Cadmium-109Cobalt-57Cobalt-60Europium-152Manganese-54Sodium-22Zinc-65Technetium-99m Beta Emitters Strontium-90Thallium-204Carbon-14Tritium Alpha Emitters Polonium-210Uranium-238 Multiple Radiation Emitters Cesium-137Americium-241 Effects of Radionuclides on Organisms Radioactivity exists in nature, but radionuclides can cause radioactive contamination and radiation poisonin if find their way into the environment or an organism is over-exposed. The type of potential damage depends on the type and energy of the emitted radiation. Typically, radiation exposure causes burns and cell damage. Radiation can cause cancer, but it might not appear for many years following exposure. Sources International Atomic Energy Agency ENSDF database (2010).Loveland, W.; Morrissey, D.; Seaborg, G.T.

Back-to-School After Hurricane Katrina

Back-to-School After Hurricane Katrina Contributed by Associate Writer Nicole Harms It has been a year since the devastation of Hurricane Katrina. As children around the country are out buying their school supplies, what will the children affected by Katrina be doing? How did Hurricane Katrina affect the schools of New Orleans and the other areas that were affected? As a result of Hurricane Katrina in New Orleans alone, 110 out of 126 public schools were completely destroyed. The children who survived the storm were displaced to other states for the rest of the school year. It is estimated that close to 400,000 students from Katrina-ravaged areas had to move in order to attend school. Around the country, school children, churches, PTAs, and other organizations have had school supply drives to help replenish the schools and students who were affected by Katrina. The Federal government has donated a substantial amount of money specifically for the cause of rebuilding post-Katrina schools. After a year, efforts have begun to rebuild in New Orleans and the other surrounding areas, but significant struggles face these schools. First, many of the students who were displaced have not returned, so there are fewer students to teach. The same goes for the staff of these schools. Many people had their homes completely destroyed, and have no intention of returning to the area. There is light at the end of the proverbial tunnel, though. On Monday, August 7, eight public schools in New Orleans opened. The city is attempting to transform the traditionally poor public schools in this area as they rebuild. With those eight schools, 4,000 students can now return to class in their hometown. There are forty schools scheduled to open in September, which will provide for 30,000 more students. The school district had 60,000 students before Hurricane Katrina hit. What will school be like for these kids? New buildings and materials may serve to make the schools better than they were before the storm, but no doubt children will be reminded every day of the devastation they just lived through. As they go to school without friends who are no longer in the city due to the effects of the storm, they will always be reminded of the horrors of Hurricane Katrina. The schools have had trouble finding enough teachers for the classrooms. Not only were students displaced by the storm, but most of the teachers were evacuated as well. Many of these have chosen not to return, finding jobs elsewhere. The lack of qualified teachers puts the re-opening date for some schools in limbo. Students who have returned to New Orleans after Hurricane Katrina can attend any school they choose, no matter where they are living. This is part of an effort to improve the district. By giving parents the chance to choose schools, officials believe they will force all schools to improve in order to draw post-Katrina students. Teachers and staff of these post-Katrina schools will not only be teaching academics to their students but also dealing with the continuing emotional trauma these students are facing. Nearly all of their students have lost someone they knew and loved as a result of Hurricane Katrina. This creates a unique atmosphere for these teachers. This year for New Orleans schools will be a year of catching up. Students who missed large portions of last years school year will need remedial instruction. All educational records were lost to Katrina, so officials will have to begin new records for every student. While the road ahead for post-Katrina schools is a long one, the officials and staff of the newly opened schools are optimistic. They have made great strides in one years time, and have proven the depth of the human spirit. As children continue to return to New Orleans and the surrounding areas, there will be schools with open doors ready for them!

How did Julius Caesar affect Rome Research Paper

How did Julius Caesar affect Rome - Research Paper Example This allowed Caeser to have an immense number of supporters during his leadership in Rome. From Inter-Connect Universe (2011), Caesar was involved in the renovation of the Roman Republic into the Roman Empire. Caeser went ahead and transformed Italy into one province thereby linking all the provinces to one central province. However, the prize was no longer the opportunity to further advance one’s career through even more illustrious service to Rome ; it was, instead, the power to make Rome accept the terms on which one justified one’s power (Griffin M, 205). Through this problem, of social wars that was present several years back was addressed. Individuals who were non Romans were able to get full citizenship and become Romans. Only when once power became concentrated under one man did concern for Rome’s overall urban image begin to be addressed (Galinsky, 235). Caeser appointed new senators who became subservient to him. Caeser realized that the republican institutions no longer operated effectively, and that only strong and enlightened leadership could permanently end the civil warfare destroying Rome (Perry M. 86). This minimized the effects of getting political challenge in Rome. What happens to Rome and the Romans in Julius Caeser, is that in the very process by which they are brought close to an apprehension in modernity, any proximity that may be established with them may be established with them disappears in a burgeoning complexity (Melehy 225). By passing the law to allow him to install consuls and magistrates, he appointed magistrates who became his representative and not representing the Romans, and he was able to dictate to the entire Rome. Bamber (1) in his journal contended that Caesars triumph in Rome surpassed all the others. Despite the hostility of his enemies, Caeser remained

Discuss how mass production transformed architecture by focusing on Research Paper

Discuss how mass production transformed architecture by focusing on either canonical works of modern architects or the works of - Research Paper Example This article shall discuss how mass production transformed architecture, mostly focusing on either canonical works of modern architects or the works of non-architects. Body The introduction of computers have transformed design processes as well as design economics as it has also changed the quality of products which can be secured. The design software which designers have come to use has shifted from being a discerning environment and concept to a more generic mass produced design. The quality, the artistic-focused design as well as the modified quality of buildings, mostly homes, based on architects have generally been indicated for the rich and privileged members of society (Mumford, 2003). However, the traditional concept of prefabricated buildings also includes in the discussion a different type of craft not often seen among the low and middle class. Prefabs seem to be the answer to the issues on governmental housing systems, emergency shelters, as well as the need to secure envi ronmentally friendly homes (Friedman, et.al., 2013). Just as museums have guaranteed for art, the prefabrication exports effective work for the general public. This is known as the commoditization of architecture and this paper shall further discuss the need for a strong interest in prefabs and related commoditization. Prefabs are generally an encompassing term. It is easily understood within the concepts of non-architects with great interest in architecture (Harker, n.d). It is often viewed with confusion by those who are not aware of design concepts. Prefabs also do not present with a specific definition, one which would allow for a strong appreciation and showing in the market. In general, all the houses are created in the US with prefabricated elements, but mostly, they do not have the necessary elements which would indicate that they are genuinely prefab (Harker, n.d). Modular housing is generally associated with prefabricated housing, but should also not be confused with manuf actured housing, within the concepts relating to construction quality as well as associated processes. Although the manufactured homes bring up different ideas on mobile housing, which are not nearly acceptable, modular housing presents more attractive site-assembled parts. Moreover, the Building Research Establishment in Scotland indicates that prefabs, whether they be of full volumetric indication or founded on component application, the need only covers construction applications, not the end-result or product (Phillipson, 2001). In general, there are different elements of prefabs: the kit home, the panels, and the volumetric modules (Blauvelt, 2007). The kit home refers to the parts which would be delivered on site, already packed with different parts to be assembled. The panels call for additional on-site work. One of the panels is delivered in large panels, including the walls, the roof, and floor; the rest are put together by skilled labourers (Buchanan, 2007). The module home covers a complete and defined prefab home. The different parts of the home are built in the factory with all the necessary parts built together, unless the different parts are used due to issues in the transport (Blauvelt, 2007). Moreover, the volumetric module is at 90% completion after shipment. As such, securing results from delivery to the handling of keys covers a

International business and policy assignment Essay

International business and policy assignment - Essay Example Shell’s multinational marketing strategy can be assessed using the framework proposed by Johny Johansson in his book Global Marketing, which is comprised of three roles: the foreign entry role; the local marketing abroad role; and the global management role. For a multinational company like Shell, which operates in a number of countries across the globe, the framework provides essential insights into analysing its operations. In order to analyse its strategy, it is crucial to first analyse the environment in which shell operates in, and see if the difference in performance is attributed to the strategy itself, or to the strategy’s inappropriateness in relation to its environment. What shapes the behavior of a business is the degree of uncertainty in its environment. In order to assess the degree of uncertainty, it is important for us to note the key dimensions that define an organization’s environment. As Stephen Robbins (2005, pp.443-444) illustrated in his book Organizational Behavior, there are three dimensions to the environment of any business, namely capacity, volatility and complexity. Using this framework, we try to assess the environment in which the company currently operates in. The environment plays a huge impact in crafting strategy and strategic management decisions an organization makes. The strategy depends on the dimensions of the environment where it operates in, as mentioned earlier, which depends on the overall objectives of an organization. This strategy should be supported by a different structure that would carry on the fulfillment of various responsibilities and tasks to achieve the organization’s objectives. However, in implementing a chosen strategy which requires restructuring within an organization, various strategic human resource management issues should be addressed. In the case of Shell, where the recommended strategies are to promote

Consumer Protection and the Criminal Law Essay Example | Topics and Well Written Essays - 1250 words

Consumer Protection and the Criminal Law - Essay Example , the plaintiff is not the actual crime victim; it is the European Union State in which the individual resides. According to the Framework Decision 2001-Standing of Victims in Criminal Proceeding, it is the responsibility of the member states to assure that the victims who wish to be informed throughout the course of the judicial process be informed. The scope of the information provided includes information on the outcome of the judicial proceeding, information necessary to maintain the security of the victims and their families, information regarding the sentence as well as the necessary services available to help the victim (Legislation Online, 2004). The Standing represented a starting point in the treatment of crime victims but it was necessary to supplement those findings. The supplementation came in the form of the 2006 recommendations. The recommendations operated with the aim of updating the standards since the laws have changed, preventing re-victimization and offering clea r an concise guidelines aimed at ensuring that the member States treat the victims in accordance with the laws (European Committee on Crime Problems, 2006). In addition to the standing of victims in criminal proceedings the notion of restorative justice looms large. ... ustice places the needs of the victims first and foremost and justice is rendered in such a manner as to enable the victim to have optimal participation in the course of justice while encouraging accountability on the part of the offender (Rigby 82). Utilizing the notion of restorative justice, a victim may request a restorative justice as a means of making the offender cognizant of the way in which the crime has affected the victim, gaining information as a means of coming to grips with the rationale behind the crime and the reason he/she has been made a victim and finally to gain closure by being able to forgive the offender in an open manner. Restorative justice marks a stark departure from the traditional form of justice which was essentially retributive justice wherein the preliminary goal was one aimed at punishing the offender by restricting his/her liberties and/or imparting monetary restitution. This is an indirect means of rendering justice as often the terms of the punitive measures undertaken are reached with minimal input or involvement by the victim (Cartwright 81). In examining the notion of restorative justice, it is prudent that we examine the rights of victims and frame this examination within the context of applications of restorative justice. First and foremost, the rights of victims and the responsibilities of the judicial system are delineated in the Human Rights Act of 1998, the Crime Victims Charters, Code of Practice for Victims, Victims Advisory Panel and other governmental bodies including the European Council. These bodies together delineate and define the treatment of crime victims with the goal of minimizing the effects of the crime on the victim while ensuring the rights of the victimizer are not violated. The rights of crime

Final Project - Essay Example Research has shown that this disorder has been successfully treated with medication and therapy, especially for those suffering from unipolar depression, or single episode experience. For those with mixed or maniac episodes, an ongoing treatment would be necessary to stabilize their depressive moods. The Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) manual, published by the American Psychiatric Association (1994), and referred to as DSM-IV, described Major Depressive Disorder (MDD) as a serious mental disorder that profoundly disrupted the lives of those affected by the disorder. Major Depressive Disorder is classified in the DSM-IV as Axis II: Developmental Disorders and Personality Disorders. In this classification, those who fall under criteria A for a single episode of MDD, exhibited at least five of nine symptoms: 1) depressed mood of sadness or irritability; 2) gradual diminished interest or pleasure in social or personal activities; 3) significant weight loss or gain, or increased or decreased appetite; 4) insomnia or hypersomnia; 5) psychomotor agitation or retardation; 6) fatigue or loss of energy; 7) feelings of worthlessness or excessive or inappropriate guilt; 8) diminished ability to think or concentrate, or indecisiveness; and 9) recurrent thoughts of death, or suicidal thoughts. Research has shown that MDD can be caused by chemical imbalances in the brain, brought about by stress and personal loss, or by some traumatic experiences (AllPsych Online-The Virtual Psychology Classroom). MDD may also be developed through certain medical illnesses such as cancer, stroke, diabetes, and myocardial infarction (All About Depression). About 20% to 25% of those suffering from these illnesses were likely to develop this disorder. It was also found that other mental activities.

Fashion Designer Project - Term Paper Example The paper "Fashion Designer Term Project" discovers such designers as Tommy Hilfiger and Kenneth Cole. Fashion designer Tommy Hilfiger born 1951 is an American citizen. He is also the founder of Tommy Hilfiger Corporation which is a first-class lifestyle brand. At 25, Hilfiger set up a shop called the peoples place in New York City. Tommy Hilfiger is considered great because the designer designs clothes for men, women and children. Furthermore, he designs accessories too. On the other hand, Tommy Hilfiger has a positive and powerful reputation internationally because his designs are classic and trendy at the same time. Due to this, majority of his designs are preferred by the elite class. This has made his designs ironically to be very popular since people admire the high quality of his designs. Tommy Hilfiger’s anesthetic characteristic that I like the most is his use of color. Tommy choice of colors is playful but serious at the same time. This is because most of his labels are all in red, blue and white. The store has some contemporary designs that were inspired by these colors and are on display. Most of the color printing done on the shirts and dresses was inspired by Tommy Hilfiger. In some respect, I assume is a representation of his country that he is so proud of, but I think it is a statement decision. The color red is bold, sexy and passionate; a statement which I think Tommy wants the client to feel when purchasing the clothes. The color blue is cool, calm and assuring a feeling.

Tinnitus And The Psychology Of Hearing Essay Example for Free

Tinnitus And The Psychology Of Hearing Essay â€Å"Tinnitus is the subjective sensation of noise—usually described as ringing, hissing, buzzing, roaring, chirping, or clicking sounds—in the ears that cannot be attributed to any external sound† (Hannan, Sami, Wareing, 2005; Lalwani, Snow, 2005). The American Tinnitus Association (2007) estimates that about 50 million Americans experience tinnitus, with men affected more than women (Lockwood, Salvi, Burkard, 2002). â€Å"Twenty-five percent of these individuals suffer from severe enough tinnitus to prompt medical consultation†. Although a relatively common condition, the mechanisms of tinnitus are as yet poorly understood (Lalwani et al, 2005; Lockwood et al, 2002). â€Å"As discussed by Lockwood and associates (2002), there are currently two schools of thought that offer contradictory explanations as to the origin of tinnitus†. On the one hand are those who forward the hypothesis that tinnitus is mainly due to a cochlear pathology, as evidenced by the high incidence of cochlear damage in individuals with tinnitus. This is countered on the other hand by those who propose a central nervous system origin of tinnitus, as implied by the observation of tinnitus in patients with complete transections of the auditory nerve (Lockwood et al, 2002). The present paper is a review of the physiology of hearing, and an attempt to correlate it with tinnitus. Hearing is a function subserved peripherally by the ears and the auditory nerve (cranial nerve VIII), and centrally by the transverse temporal gyri of the temporal lobe (Willis, 2004). These structures altogether make up the auditory system, which primarily functions in the transduction of sounds emanating from the environment. The peripheral auditory apparatus—that is, the ear—â€Å"acts as the interface between the external environment and the individual†. Sound—actually wave vibrations—enters the external auditory canal and sets the tympanic membrane in motion. This, in turn, moves the ossicles—the maleus, incus and stapes—which causes pressure changes in the fluid-filled inner ear. Clearly, from the external environment to the inner ear, sound is carried as wave vibrations, transmitted initially through solids—cartilage and bone—and later through a fluid media—the perilymph and endolymph. The efficiency of this process—a transfer of energy from air, through solids, then through fluids—is ensured by the tympanic membrane and the ossicles, which act as an impedance-matching device (Lalwani et al, 2005). From the internal ear to the central nervous system, on the other hand, sound is interpreted as gradients of electron charges across membranes. The inner ear—principally the cochlea—is a complex composed of the bony and membranous labyrinths. The bony labyrinth component of the cochlea includes several chambers, namely the scala vestibuli and the scala tympani. The scala vestibuli connects with the vestibule and the oval window, whereas the scala tympani connect with the round window. These two chambers merge at the helicotrema, located at the cochlear apex. The membranous labyrinth component of the cochlea is the scala media, which is located between the scala vestibuli and scala tympani. As mentioned previously, the inner ear is a fluid-filled structure. Specifically, the scala vestibuli and the scala tympani are filled with perilymph, which resemble cerebrospinal fluid, while the scala media is filled endolymph, which resembles intracellular fluid (Willis, 2004). Within the cochlea is located the organ of Corti, the neural apparatus responsible for sound transduction, which is composed of several thousand hair cells, the sensory receptors for sound. At the apex of each hair cell are stereocilia, and at the base are nerve fibers that belong to the cochlear division of the eighth cranial nerve. The sound wave transmitted by the middle ear case fluid movements within the bony labyrinth, and part of the hydraulic energy of these fluid movements result in displacement of the organ of Corti. The stereocilia are deformed or bent by the shear forces produced by this relative displacement. The current concept of cochlear transduction is that displacement of the tips of the stereocilia, especially if this displacement is toward the tallest cilium (Willis, 2004), allows potassium to flow into the cell, resulting in its depolarization (Lalwani et al, 2005; Ricci, Kachar, Gale, Van Netten, 2006). The influx of potassium opens calcium channels near the base of the cell, stimulating transmitter release, thought to be glutamate or aspartate (Willis, 2004; Lalwani et al, 2005; Ricci et al, 2006), and firing of the cochlear nerve fibers. This discharge is transmitted to, from peripheral to central, the dorsal and ventral cochlear nuclei, trapezoid body, superior olivary complex, lateral lemniscus, inferior colliculus, medial geniculate nucleus of the thalamus (which gives rise to the auditory radiation), and ends in the auditory cortex located in the transverse temporal gyri of the temporal lobe (Willis, 2004; Lalwani et al, 2005). The end-result of all these is the perception of sound. The subjective perception of sound that is tinnitus could theoretically originate anywhere along the length of the auditory system. However, since the sound heard of individuals suffering from tinnitus is not attributable to any external source, the origin of tinnitus could be limited to the cochlea, specifically the organ of Corti, and the central nervous sytem (Lockwood et al, 2005). Cochlear damage, specifically damage to the hair cells of the organ of Corti, was initially believed to cause tinnitus (Eggermont, 1990; Zenner Ernst, 1993). Although auditory receptor cells have been documented to regenerate and subsequently recover functionally after damage in many vertebrates (Goode, Carey, Fuchs, Rubel, 1999; Stone Rubel, 2000; Zakir Dickman, 2006), spontaneous regeneration of mammalian hair cells does not occur (Zakir et al, 2006). Damage to hair cells, especially through prolonged exposure to supraphysiologic sound levels, may result to transmission of depolarization within the hair cell, and, thus, false perception of sound in the absence of an external source of the same. In contrast to this proposition was the hypothesis forwarded by Lockwood and companions (2002), which attributes tinnitus to central nervous system defects. â€Å"They propose that hearing loss results to reorganization of the pathways in the central auditory system†, which lead to abnormal interactions between auditory and other central pathways, as is seen in neuropathic pain. An example of this phenomenon is gaze-evoked tinnitus, â€Å"where lateral eye movements fail to produce the inhibition of the auditory cortex observed in controls†. It was proposed that the absence of this phenomenon may contribute to the false perception of sounds, that is, tinnitus (Lockwood et al, 2002). It was contended that this explanation accounted for the perception of tinnitus in individuals whose auditory nerves have already been previously transected. Lockwood and associates (2002), citing from Levine (1999), also forwarded the explanation that tinnitus results from a reduction in auditory-nerve input, â€Å"which leads to disinhibition of the dorsal cochlear nucleus and an increase in spontaneous activity in the central auditory system†. This mechanism was proposed to explain tinnitus experienced by normal individuals following exposure to noise, or placement in total silence. REFERENCES American Tinnitus Association (2007).

Exchange Rates and Interest Rates in Pakistan Analysis

Exchange Rates and Interest Rates in Pakistan Analysis Abstract This paper endeavors the relationship and the positive effect between exchange rates and interest rates in Pakistan by utilizing the foreign exchange market and current scenario of increasing interest rates because of increasing exchange rates to represent the economic position of Pakistan. The data by the researcher is all on daily basis for the above variables from the period of September 2001 to May 2008 for exchange rates, while for interest rates (6 month KIBOR) from the period of September 2001 to May 2008. The researcher implement regression model to test the effect of exchange rates progression on interest rates. So in this result, there is the issue of auto correlation exists and it shows the serial correlation between these variables. The issue should be resolved by taking time and KIBOR lag values as the dumm dependent variables. The study concludes on this way that there is the negative relationship between exchange rates and interest rates (KIBOR) in Pakistan and there i s the impact of time and KIBOR on KIBOR.. It identifies that when exchange rates increases, there is decreasing in interest rates (KIBOR). This results and relationship is consistent as predicted by Meese and Rogoff (1988). INTRODUCTION Every country has its own financial markets and it is the back bone of a countrys economy. The financial markets is divided in parts like foreign exchange market, stock market, money market, bond market etc. In this study, the researcher is focuses on the foreign exchange market, which is commonly known as Forex. It is the largest and most prolific part of financial market and defining the balancing of countrys economy, because every particular day, there are approximately one trillion amount of foreign exchange takes place in the countries around the world. The actual mechanism of the foreign exchange, that it is work as the main driving force for an any countys economy in the world. Therefore, any country in the world should challenge their currency in the global economic markets. In the exchange markets for all the countries, home country currencies trade with other foreign country currencies. The foreign exchange market system is needed for every developed and under developed cou ntry; this system known as currency in exchange determination. For the determination of the value of a currencys exchange rate, there are two main types of system is used, one is floating exchange rates system and the other is fixed exchange rates system. The intervention of government officials authorities in the foreign exchange market is to influence the exchange rate fluctuation as a worldwide phenomenon. The authorities intervene maintaining the objective to orderly market conditions that ultimately help to achieve the overall macroeconomic goals. However, the exchange rate has playing an important role in terms of the flexibility in macroeconomic framework to deal with changes in the external terms of trade, but the monetary policy also aims the national objectives of economic diversification and to support export competitiveness. The ineffective monetary policy under fixed exchange rates as compared to flexible exchange rates, but fiscal policy under both fixed and flexible exchange rates remains weaker of achieving the level of output. (R.A. Mundell, 1968). The level of currency risk changes, it has no negligible impact on the rates of change of exchange rates and on relatives rates of interest between currencies. (Clas Whilborg, 1982). The risk premium of the currency is the important factor relative to floating exchange rate system, but movements in the exchange rate are dominated by the non speculative activity and it has the adverse effect on world economy. (John bilson, 1985). The true statement that in many cases the sign of the estimated exchange rate-interest rate differential relationship is consistent with the possible predominance of financial market disturbance (R. Meese K. Rogoff, 1988). The consequences changes in the nominal interest rate reflect changes in the tightness of monetary policy. T he higher the interest rate in the country attracts the capital inflow, which causes the domestic currency appreciates, so this gets the relationship could be negative between the exchange rate and nominal interest rate differentials. (J.A. Frankel, 1979). The assets are dominated and exchange risks interest reflects the interest rate parity when different currencies affect political risk and thats why assets are issued in different currencies. Thus the interest differentials to the political risk of future capital control must be distinguished due to the effective tax that controls the place in interest earnings. (M.P. Dooley P. Isard, 1980). The concept of political risk is that the probability authority of the state will be interposed between investors in one country and investment opportunities in other countries that is the probability that controls the imposed on capital flows. (R.Z. Aliber, 1973). If price levels and exchange rate are significantly volatile and cannot be cos tly hedged, are adversely affected in the real value of the domestic currency. There is some evidence that exchange rate fluctuations are a priced factor in cross sections of stock return converted into a common currency. (W. Bailey P. Chung, 1995). In the perfect mobility the exchange rate movements and an adjustment of goods market is relative to asset market and consistent expectations. The extends that output responds to a monetary expansion in the short run, this acts as an effect on exchange depreciation which lead to an increase in interest rates. (Rudiger Dornbusch, 1976). The foreign exchange gain or loss is made in the course of covering; consider being capital assets, so this gain or loss treated on capital account. This shows the highly sensitive interest dynamics with exchange rates. (M.D. Levi, 1977). The variability of industrial production output will be higher in the regime of fixed exchange rates instead of regime of flexible exchange rates. (Flood Hodrick, 1986) . The effect of consumption goods purchases by the government is not the private utility, but per capita real government expenditure are the composite of individual consumption of goods. So notice that the demand of money its depends on consumption of goods rather than income and that is the important distinction of closed economies.(Obstfeld Rogoff, 1995). The fixed and floating exchange rates depend on higher welfare yield and on the nature of sticky prices, so the risk would be shared and there are some opportunities to aware. The evidence, which should give opportunities about price setting and risk sharing are not refined and not to make the definite conclusions for the optimal regime of the exchange rate of that country. There are three types of ways which gives stickiness in prices, the prices which would set by the firms in their own currencies, the firms would set the prices for consumers currencies, or firms would set the prices in the currencies of producers. (Charles En gel, 2001). When the exchange rates changes, it may cause to appear the changes in relative prices and make to generate additional uncertainty for equilibrium in markets. However, there is also defining that the changes in terms of trade would play the larger role of changes in the exchange rates which affect the variability of exchange rates. (A.C. Stockman, 1980). This study explores to investigate the determinants of exchange rates in developing country such as Pakistan. The framework of this study is concern to be conceptual and theoretical and is to set up the ground of unidirectional causality from exchange rates to economy. In principal, it determines the exchange rates relationship with interest rates so it will spurs the determinants in Pakistan with related to the economy. This view implies that the choice of an exchange rates regime be a relatively simple, if countries were faced to intervene regularly in the foreign exchange market to stabilize, therefore the monetary authorities intervene with the objective of maintaining orderly market conditions, which ultimately help to achieve the overall macroeconomic goals. The discretionary nature of the existing monetary policy in Pakistan is inflation, and it is targeting to hit on the Pakistani economy by focusing attention on the monetary policy. So the government of Pakistan is to make t heir monetary policy more transparent for achieving their explicit goal, and decreasing the inflation. Therefore, it is increasing the publics understanding of the central banks strategy to deliver the target, so the State Bank of Pakistan will help to provide an anchor for inflation expectations in the economy. The State Bank of Pakistan (SBP) has accorded a high priority to achieving a low rate of inflation, and the monetary policy also aims to support the objectives of the national country of Pakistan to meet their diversified economy and competitiveness in the export from other countries of the world. This study will also helpful to the SBP to developed their awareness of the relationship of exchange rates with KIBOR, so SBP may observed the controversy of their ups and downs fluctuations so it may controlled significantly. The bank treasury department should get the help because, they have continuously meet the exchange rates and make transactions of the countrys currency with others country currencies, so it should make them identify that if exchange rates increases or decreases it should not make effect on interest rates but their should be some inverse effect in nature. This effect should create controversy in the country economy so the central bank should make some authorized decisi on to controlled the exchange rates and interest rates The thesis is structures as follows. Chapter II provides literature review. Chapter III defines the outline of variables, their sample size, data sources and its formatting and the model. Chapter IV explains our findings and results. Finally Chapter V reports conclusion Chapter II Literature Review: This study relates to examine the relationship and effect between exchange rates with interest rates. Numbers of studies have done by the researchers, Robert A. Mundell, (1961), Bela Balassa (1964), Robert Z. Aliber, (1973), Rudiger Dornbusch, (1976), Richard A. Meese Kenneth Rogoff (1982), H.M.S Gerlach (1988), to investigate the determinants of exchange rates have applied in the world exchange rates market and help for different countries in their market development and economic growth. Researchers attempted to exemplify whether, how and to what extent the determinants of exchange rates market can contribute to the process of economic growth. Purchasing Power Parity Theory: The purchasing power parity theory doctrine means different things to different people. It has two versions of this theory that can be called the absolute and the relative interpretation. The first version of purchasing power theory calculated as a ratio of consumer goods prices for any country would tend to the equilibrium rates of exchange. In the second version of relative interpretation the rate of exchange rate would be determined between two countries and quoted with general levels of prices of two countries. It amend the international trade theory which would be the part of PPP, in which introducing the non-traded goods (services), but the advantage is greater in regards of traded goods than non-traded goods, because of the assumptions of marginal rates of transformation. The relationship between purchasing power parity and exchange rates provides the international comparison of national incomes and living standards (Bela Balassa, 1964). (Lawrence H. Officer, 1976) is the rese archer which gave another review of this purchasing power parity theory. It has define two applications in economics, the first application use of the conversion factor to transfer the data in one national way to another. The use of PPP is mainly the body of (index number theory) and applications of GDP that have improved over the years and path breaking studies in the area continue to appear. The second application of PPP has not the widespread acceptance, which has remained the unsophisticated applications. A.C. Stockman, (1980), develops the model of determination of exchange rates and prices of goods. The changes in prices of goods due to supply and demand would affect the changes in exchange rates with deviations of purchasing power parity. The changes in exchange rates have failed to resemble the changes in prices of goods, because exchange rates more volatile than prices levels and inflation rates. The research proposes the equilibrium of exchange rates behavior and different international goods that would have been traded. This relationship cannot be exploited by the government, because the greater the changes in terms of trade the larger the changes in exchange rates variability. The deviations from PPP persist that variation of exchange rates more than ratios of price indexes. The results found the two interpretation of the relationship between exchange rates and terms of trade. In the first, the causes that affect the changes in exchange rates would also affect the change in te rms of trade because prices of goods do not adjust to clear the markets. This interpretation would also found in the research of Dornbusch (1976), and Isard (1977), they formally differentiates the system with respect to exchange rates and allow prices to change but not the changing in asset stocks. The another interpretation presented the elasticity approach of the foreign exchange market and the relation between the trade and exchange rates. Real supply and demand shocks affect prices and the derived demand of exchange rates. The affect of such a shift has the advantage to raise the value of currency in terms of foreign currencies relative PPP. These changes in demand for foreign exchange would result the supply and demand shocks and that should affect the equilibrium of exchange rates. In second interpretation the expected rate of change of exchange rates revealed on the forward foreign exchange market. This should be related the anticipated change in the terms of trade and the i nflation differentials. A persuasive argument about the level of exchange rates is only associated with not causes of the relative prices changes. Clas Wihlborg, (1982), examined the relation of interest rates, exchange rate and currency risks in this research. It identifies the test which empirically impact of currency on interest rates and exchange rates. In this research there are three different ways in which the importance of currency risks for interest rate and exchange rate determination. First different risk characteristics of assets denominated in different currencies. Second changes in the level of risks that affect the elastic ties of substitutes among different assets and the monetary policy. Third changes in the level of risks on alternative assets which have a direct impact on rates of return. This research used the three specifications of the dependent variable to test the theory, firstly the rates of return is adjusted for the expected rate of changes in the exchange rates, second difference between nominal rates of interest and third rate of change of deviation from the exchange rate. The results presented here that substantiate the changes in the level of currency risk have a non-negligible impact on the rates of change of exchange rates and on relatives rates of interest between currencies. The risks explain the small share of variation in these variables. Another results indicate that the nominal interest rate seem to adjust in fiscal policies and savings behavior but not affect real rates of interest. But changes in relative risks level would affect relative rates on interest these changes still be important for the substitutability between assets of different currency denominations. Richard Meese Kenneth Rogoff, (1983), analysis the out of sample forecasting accuracy on various models. It estimated the horizons of the dollar with different country currencies, like Dutch mark, Japanese yen, and Britain pound that traded to weight the dollar exchange rates. Its also studied the flexible exchange rates with the monetary models of sticky price, so the model of sticky price, which incorporates the current account. The first model is structural models in which it requires to generate the forecasts of exchange rates and explanatory variables. It contains the explanatory power, but its predicted badly because the explanatory variables are difficult to predict. The second is the univariate times series model in which identify a variety of prefiltering techniques involve differencing, de-seasonalizing and removing time trends. The relative performance of these techniques is of interest in itself. The third model use is the random walk model; it should also link with this univariate time series model. It uses as the predictor of the current spot rate with the entire future spot rate, and it requires no estimation. In this research the performance of estimated univariate time series models or candidate structural model is so worse. From a methodological stand point the view that the out of sample model fit is an important criterion when evaluating exchange rate, but the estimation of out of sample is failure with time series models, that are well approximated the major country exchange rates. John Bilson, (1985), gives the empirical findings about macro economic and flexible exchange rate of the U.S dollar related to PPP theory. From the perspective of this research in which sluggish price adjustment in the commodity markets resulted in increased variability in exchange rates. For the demonstration of result it is important because the instability of floating exchange rate could be due to the inherent differences between commodity and foreign exchange markets. The determination of the expected future rate is impossible, because it is more difficult to reject the forward parity condition. The major part of the forward parity is the variation in the premium is due to the forecast. The object of this research is to determine that if the forward parity failed is the cause of instability in the same way that the failure of purchasing power parity. The findings develop that currency risk premium is the important factor relative to floating rate system, and movement in the excha nge rate are dominated by the non speculative activity and it has the adverse effect on world economy. Roger D. Huang, (1987), evaluate that the expected change in the exchange rate of two countries equals the expected differentials in their inflation rats over the same holding period. It makes the empirical evidence link with PPP theory and obtained that the changes in expected nominal exchange rate is appear to deviate inflation rate systematically. It relates the PPP based on the constraint that, in efficient market the net return to speculators engaging in speculation on goods in the foreign country. The purpose of this research is to know the equality restriction between expected nominal exchange rate and expected inflation rate differentials. The investigation should have the result that the evidence is inconsistent with the current floating exchange rates over the major industrialized countries. Since the test perform meaningful in conjunction with market efficiency and simply indicate the failure expectations. John Doukas Abdul Rahman, (1987), conducted the unit root test for the presence of evidence from the foreign exchange futures market, and gets the representation of foreign exchange currency future prices. The research describes the procedure from the foreign exchange future markets on five different currencies with varying maturity. It was found that presence in the series may cause the OLS estimates and its true value leading to errors, for small sample sizes the model has smaller forecast error. The process generate the log of currencies future rates by random walk, and it is consistent with other model of asset price determination that they imply the mean and dispersion of returns that don not change over short time period. But in general if follow the random walk; it is line with (Meese Singletons) findings from the spot and forward exchange market. H.J. Edison, (1987), addresses that whether PPP is valid in the long run movements in exchange rates, though it is failed in the short run. However number of studies was conduct for the behavior of exchange rates, Alder Lehmann (1983), Frankel (1986), developed more statistical techniques to examine the validity of exchange rates in the long run. Both of these have provided the evidence that PPP does not hold the exchange rates behavior in the long run. This research also incorporates the error correction mechanism and discusses the empirical results which generally show the result of failure of exchange rate support by PPP in the long run. In general, the result indicates the force which exists in the economy for driving the exchange rates towards the PPP equilibrium. The main conclusion from this research is the PPP relationship does not represents the exchange rates n the long run holding, so that the PPP permanent deviations cannot ruled out. This shows the reinforcement of PPP theory that was tested the fixed rate counterpart and the equalization of prices across countries, and it supports an interpretation of the PPP doctrine. This proportionality between the exchange rates and price level emerges in the long run. Richard Meese Kenneth Rogoff, (1988), examined the relationship between real exchange rates and real interest rate differentials from different countries. It based on the joint hypothesis that the prices of the domestic currency are sticky and the disturbances of monetary policy are predominant, which would found the little evidence of a stable relationship between interest rates and exchange rates. It is true that in many cases the sign of the estimated exchange rate and interest rate differential relationship is consistent with the possible predominance of financial market disturbances, but the relationship is not stable enough to be statistically significant. In Quasi reduced form real exchange rate models, examined the real versions of alternative rational expectations monetary models of exchange rate determination. In the nominal rate models, the exchange rate depends on fundamentals such as relative national money supplies, real incomes, short-term interest rates, expected inf lation differentials, and cumulated trade balances. The rationale view for this approach is that the nominal exchange rates poor performance is primarily attributable to money demand disturbances, so it can define the close relationship between there real interest differentials and real exchange rates, because, in the class of monetary models considered here, unanticipated money demand disturbances affect both variables proportionately. Feinberg Seth Kaplan, (1992), evaluate and interacts the real exchange rates index expectations is developed and used to explore the role of determination on domestic producer prices. The fact that time path of the exchange rate will directly affect the input costs, and the price of substitutes strongly. To examine the links between both actual and anticipated movements in the dollar and relative domestic producer prices, it chooses to analyze price responses to real exchange rate changes. The effect is dependent on the nature of substitutability between imports and domestic goods. The major finding is that the period of appreciation and depreciation over the past 10 years to inhibit the pass through in to domestic prices. In depreciation the market share to enjoy the continued good times kept prices other than expected. Warren Bailey Peter Chung, (1995), considers the study that the impact of fluctuations on exchange rates and political risk is on the risks premium and is reflected the individual equity returns. It suggests the factors which is common for emerging market equity, currency and debt markets, and make empirical implications to evaluate corporate and portfolio management. If price levels and exchange rate are significantly volatile and cannot be costly hedged, are adversely affected in the real value of the domestic currency. Some evidence that exchange rate fluctuations are a priced factor in cross sections of stock return converted into a common currency. The purpose of this research is to explore the impact of fluctuations on exchange rates and political risk which is consider on stock process of individual companies from the same country. The extent of measurement is that, which exposure factors explain cross sections of returns on individual securities and industry portfolios. The result suggests that the exchange rates and political risks could be significant in equity markets. The result also suggests that the risk premium can be time varying and not be detected by assuming constantly. This research shows the results that it did not find the evidence of the equity market premiums for the currency and political risk. It complements the importance to attach the exchange rates and political risk in the international finance. J.R. Lothian M.P. Taylor, (1996), examines the real exchange rate behavior, and explains the variations in sample of stationary univariate equations in real exchange rates. It investigates the additional insight in the exchange rates behavior that can be gained by considering the floating rate from the perspective of the data. These issues can be best understood on the subject of real exchange rates stability between the currencies of the major industrialized countries. Some of the pre-float studies support the fairly stable exchange rates in the long run. Subsequently, Dornbusch (1976), Frenkel (1981), gave largely as the result of studies published, and reject the hypothesis of random walk behavior of real exchange rates. The PPP shows the empirical movements in real exchange rates were highly persistent and effective; although the PPP is reject the hypothesis of non-stationary behavior of real exchange rates in the long run. The result of this research shows that the longest span of two countries exchange rates are significantly mean reverting. The first model result indicates the 80 percent of the variation in the exchange rates of the history data of two countries. By using of another model, the results explaining the performance of remarkably well in the floating, so that they produce better forecasts of the actual exchange rates. In line with recent studies, it fined that this process of mean reverting is quit slow, with estimated adjustment of data. In the long run the PPP equilibrium is remaining a useful empirical approximation. The deviations of the PPP that observe are consistent with the existence of slowly mean reverting influences, which may be real or monetary regimes. Theory of Optimum Currency Areas: The theory of optimum currency areas, which is usually presented the other name called flexible exchange rate system, but it is proponents as a device of depreciation that take the place of unemployment when the balance of payment is deficit and appreciation when it replace inflation when it is surplus. The problem can be exposed and more revealing by defining a currency area within when exchange rates are fixed. To this three answer can be given; first certain parts of the world are going processes of economic integration, so new experience can be made and at what constitutes the optimum currency area can give the meaning of these experiments. Second those countries that have flexible exchange rates are likely to face problems with the theory of optimum currency areas, so it does not coincide the optimum currency areas with the national currency. Third the idea that illustrates the functions of currencies which have been treated in economic literature, and sometimes neglected in the problems of economic policy. In the currency area, different currency countries including national country currencies interact pace of employment in deficit, because there is the willingness to inflation by the surplus countries. The argument for flexible exchange rate system is based on national currencies, and is valid about mobility of factor, so if it is high in the country and low in the foreign countries, the flexible exchange rates system on home country currencies might work effectively. The concept of optimum currency area has practically applicable only in those areas, where the state has the political organization in the country. The factor mobility is most considered is more relative rather than absolute concept, with both industrial and geographical. It likely to change the alterations with time over time in conditions, where the conditions of political and economic stability. Money is the convenience that restricts the optimum number of currencies, so in terms of this argument the optimum currency area which is composed in number of countries. (Robert A. Mundell, 1961). In another review the author defines the stabilization of capital mobility policy under the exchange rates which is fixed and flexible in the currencies markets; it concerns the theoretical and practical approach of the increased mobility of capital. The assumption is that the interest rate differentials from the level of abroad cannot maintain by the country, if there is the degree of mobility. The securities system are perfect substitutes, because different currencies are involved can be taken in the perfect mobilization, and there exchange rates expected to persist indefinitely, but the forward and spot exchange rate are identical. It identify the monetary and fiscal policy, in which monetary policy assumed the open market purchase of securities while fiscal policy is to form of increase in government spending and financed by an increased in public debt. Its effect the floatin g exchange rate result when monetary policy does not intervene in the exchange market, but it intervene the fixed exchange rates, when the buying and selling of international reserves at the rate of fixed price. The results of this research analyze that, the fixed exchange rates is become a device for the monetary policy and for the levels of reserve, whereas the flexible exchange rates becomes a device for the fiscal policy and for the balance of trade, but policies are unaffected to the level of output and employment. The fixed exchange rates in the perfect mobility will lead to the breakdown as the absence of gold sterilization. The gold sterilization is frustrated the capital outflows and offsetting monetary changes through the exchange rates equalization. The conclude remarks is that, the fixed exchange rates as compared to flexible exchange rates is ineffective under monetary policy, but in fiscal policy both the exchange rates either fixed or flexible are remains weaker for a chieving the level of output. The flexible exchange rates under fiscal policy to play some role in employment policy that can be expected, while monetary policy can have influence on output under fixed exchange rates. In this possibility existing, it wills lesser extent in the future. (R.A. Mundell, 1968). J.H. Makin, (1978), analysis the way to deal the risks involved in foreign exchange currency positions but exchange rates are uncertain. It incorporates the exchange rate changes with the changes in the determination of overall hedging strategy. The purpose is to survey the literature rather to examine the logic on hedge no hedge strategy and to suggest the viewing problem of exchange risk. It identifies the exchange risk diversification in two groups. First diversification investigates the exchange risk with the investor point of view selecting the locations of firms in different countries which denominated in different currencies. The second considers exchange risk with the firm manager point of view to decrease the impact of exchange rate fluctuations. The study concentrates the exchange risk and not overall corporate risk, so the analysis of co Exchange Rates and Interest Rates in Pakistan Analysis Exchange Rates and Interest Rates in Pakistan Analysis Abstract This paper endeavors the relationship and the positive effect between exchange rates and interest rates in Pakistan by utilizing the foreign exchange market and current scenario of increasing interest rates because of increasing exchange rates to represent the economic position of Pakistan. The data by the researcher is all on daily basis for the above variables from the period of September 2001 to May 2008 for exchange rates, while for interest rates (6 month KIBOR) from the period of September 2001 to May 2008. The researcher implement regression model to test the effect of exchange rates progression on interest rates. So in this result, there is the issue of auto correlation exists and it shows the serial correlation between these variables. The issue should be resolved by taking time and KIBOR lag values as the dumm dependent variables. The study concludes on this way that there is the negative relationship between exchange rates and interest rates (KIBOR) in Pakistan and there i s the impact of time and KIBOR on KIBOR.. It identifies that when exchange rates increases, there is decreasing in interest rates (KIBOR). This results and relationship is consistent as predicted by Meese and Rogoff (1988). INTRODUCTION Every country has its own financial markets and it is the back bone of a countrys economy. The financial markets is divided in parts like foreign exchange market, stock market, money market, bond market etc. In this study, the researcher is focuses on the foreign exchange market, which is commonly known as Forex. It is the largest and most prolific part of financial market and defining the balancing of countrys economy, because every particular day, there are approximately one trillion amount of foreign exchange takes place in the countries around the world. The actual mechanism of the foreign exchange, that it is work as the main driving force for an any countys economy in the world. Therefore, any country in the world should challenge their currency in the global economic markets. In the exchange markets for all the countries, home country currencies trade with other foreign country currencies. The foreign exchange market system is needed for every developed and under developed cou ntry; this system known as currency in exchange determination. For the determination of the value of a currencys exchange rate, there are two main types of system is used, one is floating exchange rates system and the other is fixed exchange rates system. The intervention of government officials authorities in the foreign exchange market is to influence the exchange rate fluctuation as a worldwide phenomenon. The authorities intervene maintaining the objective to orderly market conditions that ultimately help to achieve the overall macroeconomic goals. However, the exchange rate has playing an important role in terms of the flexibility in macroeconomic framework to deal with changes in the external terms of trade, but the monetary policy also aims the national objectives of economic diversification and to support export competitiveness. The ineffective monetary policy under fixed exchange rates as compared to flexible exchange rates, but fiscal policy under both fixed and flexible exchange rates remains weaker of achieving the level of output. (R.A. Mundell, 1968). The level of currency risk changes, it has no negligible impact on the rates of change of exchange rates and on relatives rates of interest between currencies. (Clas Whilborg, 1982). The risk premium of the currency is the important factor relative to floating exchange rate system, but movements in the exchange rate are dominated by the non speculative activity and it has the adverse effect on world economy. (John bilson, 1985). The true statement that in many cases the sign of the estimated exchange rate-interest rate differential relationship is consistent with the possible predominance of financial market disturbance (R. Meese K. Rogoff, 1988). The consequences changes in the nominal interest rate reflect changes in the tightness of monetary policy. T he higher the interest rate in the country attracts the capital inflow, which causes the domestic currency appreciates, so this gets the relationship could be negative between the exchange rate and nominal interest rate differentials. (J.A. Frankel, 1979). The assets are dominated and exchange risks interest reflects the interest rate parity when different currencies affect political risk and thats why assets are issued in different currencies. Thus the interest differentials to the political risk of future capital control must be distinguished due to the effective tax that controls the place in interest earnings. (M.P. Dooley P. Isard, 1980). The concept of political risk is that the probability authority of the state will be interposed between investors in one country and investment opportunities in other countries that is the probability that controls the imposed on capital flows. (R.Z. Aliber, 1973). If price levels and exchange rate are significantly volatile and cannot be cos tly hedged, are adversely affected in the real value of the domestic currency. There is some evidence that exchange rate fluctuations are a priced factor in cross sections of stock return converted into a common currency. (W. Bailey P. Chung, 1995). In the perfect mobility the exchange rate movements and an adjustment of goods market is relative to asset market and consistent expectations. The extends that output responds to a monetary expansion in the short run, this acts as an effect on exchange depreciation which lead to an increase in interest rates. (Rudiger Dornbusch, 1976). The foreign exchange gain or loss is made in the course of covering; consider being capital assets, so this gain or loss treated on capital account. This shows the highly sensitive interest dynamics with exchange rates. (M.D. Levi, 1977). The variability of industrial production output will be higher in the regime of fixed exchange rates instead of regime of flexible exchange rates. (Flood Hodrick, 1986) . The effect of consumption goods purchases by the government is not the private utility, but per capita real government expenditure are the composite of individual consumption of goods. So notice that the demand of money its depends on consumption of goods rather than income and that is the important distinction of closed economies.(Obstfeld Rogoff, 1995). The fixed and floating exchange rates depend on higher welfare yield and on the nature of sticky prices, so the risk would be shared and there are some opportunities to aware. The evidence, which should give opportunities about price setting and risk sharing are not refined and not to make the definite conclusions for the optimal regime of the exchange rate of that country. There are three types of ways which gives stickiness in prices, the prices which would set by the firms in their own currencies, the firms would set the prices for consumers currencies, or firms would set the prices in the currencies of producers. (Charles En gel, 2001). When the exchange rates changes, it may cause to appear the changes in relative prices and make to generate additional uncertainty for equilibrium in markets. However, there is also defining that the changes in terms of trade would play the larger role of changes in the exchange rates which affect the variability of exchange rates. (A.C. Stockman, 1980). This study explores to investigate the determinants of exchange rates in developing country such as Pakistan. The framework of this study is concern to be conceptual and theoretical and is to set up the ground of unidirectional causality from exchange rates to economy. In principal, it determines the exchange rates relationship with interest rates so it will spurs the determinants in Pakistan with related to the economy. This view implies that the choice of an exchange rates regime be a relatively simple, if countries were faced to intervene regularly in the foreign exchange market to stabilize, therefore the monetary authorities intervene with the objective of maintaining orderly market conditions, which ultimately help to achieve the overall macroeconomic goals. The discretionary nature of the existing monetary policy in Pakistan is inflation, and it is targeting to hit on the Pakistani economy by focusing attention on the monetary policy. So the government of Pakistan is to make t heir monetary policy more transparent for achieving their explicit goal, and decreasing the inflation. Therefore, it is increasing the publics understanding of the central banks strategy to deliver the target, so the State Bank of Pakistan will help to provide an anchor for inflation expectations in the economy. The State Bank of Pakistan (SBP) has accorded a high priority to achieving a low rate of inflation, and the monetary policy also aims to support the objectives of the national country of Pakistan to meet their diversified economy and competitiveness in the export from other countries of the world. This study will also helpful to the SBP to developed their awareness of the relationship of exchange rates with KIBOR, so SBP may observed the controversy of their ups and downs fluctuations so it may controlled significantly. The bank treasury department should get the help because, they have continuously meet the exchange rates and make transactions of the countrys currency with others country currencies, so it should make them identify that if exchange rates increases or decreases it should not make effect on interest rates but their should be some inverse effect in nature. This effect should create controversy in the country economy so the central bank should make some authorized decisi on to controlled the exchange rates and interest rates The thesis is structures as follows. Chapter II provides literature review. Chapter III defines the outline of variables, their sample size, data sources and its formatting and the model. Chapter IV explains our findings and results. Finally Chapter V reports conclusion Chapter II Literature Review: This study relates to examine the relationship and effect between exchange rates with interest rates. Numbers of studies have done by the researchers, Robert A. Mundell, (1961), Bela Balassa (1964), Robert Z. Aliber, (1973), Rudiger Dornbusch, (1976), Richard A. Meese Kenneth Rogoff (1982), H.M.S Gerlach (1988), to investigate the determinants of exchange rates have applied in the world exchange rates market and help for different countries in their market development and economic growth. Researchers attempted to exemplify whether, how and to what extent the determinants of exchange rates market can contribute to the process of economic growth. Purchasing Power Parity Theory: The purchasing power parity theory doctrine means different things to different people. It has two versions of this theory that can be called the absolute and the relative interpretation. The first version of purchasing power theory calculated as a ratio of consumer goods prices for any country would tend to the equilibrium rates of exchange. In the second version of relative interpretation the rate of exchange rate would be determined between two countries and quoted with general levels of prices of two countries. It amend the international trade theory which would be the part of PPP, in which introducing the non-traded goods (services), but the advantage is greater in regards of traded goods than non-traded goods, because of the assumptions of marginal rates of transformation. The relationship between purchasing power parity and exchange rates provides the international comparison of national incomes and living standards (Bela Balassa, 1964). (Lawrence H. Officer, 1976) is the rese archer which gave another review of this purchasing power parity theory. It has define two applications in economics, the first application use of the conversion factor to transfer the data in one national way to another. The use of PPP is mainly the body of (index number theory) and applications of GDP that have improved over the years and path breaking studies in the area continue to appear. The second application of PPP has not the widespread acceptance, which has remained the unsophisticated applications. A.C. Stockman, (1980), develops the model of determination of exchange rates and prices of goods. The changes in prices of goods due to supply and demand would affect the changes in exchange rates with deviations of purchasing power parity. The changes in exchange rates have failed to resemble the changes in prices of goods, because exchange rates more volatile than prices levels and inflation rates. The research proposes the equilibrium of exchange rates behavior and different international goods that would have been traded. This relationship cannot be exploited by the government, because the greater the changes in terms of trade the larger the changes in exchange rates variability. The deviations from PPP persist that variation of exchange rates more than ratios of price indexes. The results found the two interpretation of the relationship between exchange rates and terms of trade. In the first, the causes that affect the changes in exchange rates would also affect the change in te rms of trade because prices of goods do not adjust to clear the markets. This interpretation would also found in the research of Dornbusch (1976), and Isard (1977), they formally differentiates the system with respect to exchange rates and allow prices to change but not the changing in asset stocks. The another interpretation presented the elasticity approach of the foreign exchange market and the relation between the trade and exchange rates. Real supply and demand shocks affect prices and the derived demand of exchange rates. The affect of such a shift has the advantage to raise the value of currency in terms of foreign currencies relative PPP. These changes in demand for foreign exchange would result the supply and demand shocks and that should affect the equilibrium of exchange rates. In second interpretation the expected rate of change of exchange rates revealed on the forward foreign exchange market. This should be related the anticipated change in the terms of trade and the i nflation differentials. A persuasive argument about the level of exchange rates is only associated with not causes of the relative prices changes. Clas Wihlborg, (1982), examined the relation of interest rates, exchange rate and currency risks in this research. It identifies the test which empirically impact of currency on interest rates and exchange rates. In this research there are three different ways in which the importance of currency risks for interest rate and exchange rate determination. First different risk characteristics of assets denominated in different currencies. Second changes in the level of risks that affect the elastic ties of substitutes among different assets and the monetary policy. Third changes in the level of risks on alternative assets which have a direct impact on rates of return. This research used the three specifications of the dependent variable to test the theory, firstly the rates of return is adjusted for the expected rate of changes in the exchange rates, second difference between nominal rates of interest and third rate of change of deviation from the exchange rate. The results presented here that substantiate the changes in the level of currency risk have a non-negligible impact on the rates of change of exchange rates and on relatives rates of interest between currencies. The risks explain the small share of variation in these variables. Another results indicate that the nominal interest rate seem to adjust in fiscal policies and savings behavior but not affect real rates of interest. But changes in relative risks level would affect relative rates on interest these changes still be important for the substitutability between assets of different currency denominations. Richard Meese Kenneth Rogoff, (1983), analysis the out of sample forecasting accuracy on various models. It estimated the horizons of the dollar with different country currencies, like Dutch mark, Japanese yen, and Britain pound that traded to weight the dollar exchange rates. Its also studied the flexible exchange rates with the monetary models of sticky price, so the model of sticky price, which incorporates the current account. The first model is structural models in which it requires to generate the forecasts of exchange rates and explanatory variables. It contains the explanatory power, but its predicted badly because the explanatory variables are difficult to predict. The second is the univariate times series model in which identify a variety of prefiltering techniques involve differencing, de-seasonalizing and removing time trends. The relative performance of these techniques is of interest in itself. The third model use is the random walk model; it should also link with this univariate time series model. It uses as the predictor of the current spot rate with the entire future spot rate, and it requires no estimation. In this research the performance of estimated univariate time series models or candidate structural model is so worse. From a methodological stand point the view that the out of sample model fit is an important criterion when evaluating exchange rate, but the estimation of out of sample is failure with time series models, that are well approximated the major country exchange rates. John Bilson, (1985), gives the empirical findings about macro economic and flexible exchange rate of the U.S dollar related to PPP theory. From the perspective of this research in which sluggish price adjustment in the commodity markets resulted in increased variability in exchange rates. For the demonstration of result it is important because the instability of floating exchange rate could be due to the inherent differences between commodity and foreign exchange markets. The determination of the expected future rate is impossible, because it is more difficult to reject the forward parity condition. The major part of the forward parity is the variation in the premium is due to the forecast. The object of this research is to determine that if the forward parity failed is the cause of instability in the same way that the failure of purchasing power parity. The findings develop that currency risk premium is the important factor relative to floating rate system, and movement in the excha nge rate are dominated by the non speculative activity and it has the adverse effect on world economy. Roger D. Huang, (1987), evaluate that the expected change in the exchange rate of two countries equals the expected differentials in their inflation rats over the same holding period. It makes the empirical evidence link with PPP theory and obtained that the changes in expected nominal exchange rate is appear to deviate inflation rate systematically. It relates the PPP based on the constraint that, in efficient market the net return to speculators engaging in speculation on goods in the foreign country. The purpose of this research is to know the equality restriction between expected nominal exchange rate and expected inflation rate differentials. The investigation should have the result that the evidence is inconsistent with the current floating exchange rates over the major industrialized countries. Since the test perform meaningful in conjunction with market efficiency and simply indicate the failure expectations. John Doukas Abdul Rahman, (1987), conducted the unit root test for the presence of evidence from the foreign exchange futures market, and gets the representation of foreign exchange currency future prices. The research describes the procedure from the foreign exchange future markets on five different currencies with varying maturity. It was found that presence in the series may cause the OLS estimates and its true value leading to errors, for small sample sizes the model has smaller forecast error. The process generate the log of currencies future rates by random walk, and it is consistent with other model of asset price determination that they imply the mean and dispersion of returns that don not change over short time period. But in general if follow the random walk; it is line with (Meese Singletons) findings from the spot and forward exchange market. H.J. Edison, (1987), addresses that whether PPP is valid in the long run movements in exchange rates, though it is failed in the short run. However number of studies was conduct for the behavior of exchange rates, Alder Lehmann (1983), Frankel (1986), developed more statistical techniques to examine the validity of exchange rates in the long run. Both of these have provided the evidence that PPP does not hold the exchange rates behavior in the long run. This research also incorporates the error correction mechanism and discusses the empirical results which generally show the result of failure of exchange rate support by PPP in the long run. In general, the result indicates the force which exists in the economy for driving the exchange rates towards the PPP equilibrium. The main conclusion from this research is the PPP relationship does not represents the exchange rates n the long run holding, so that the PPP permanent deviations cannot ruled out. This shows the reinforcement of PPP theory that was tested the fixed rate counterpart and the equalization of prices across countries, and it supports an interpretation of the PPP doctrine. This proportionality between the exchange rates and price level emerges in the long run. Richard Meese Kenneth Rogoff, (1988), examined the relationship between real exchange rates and real interest rate differentials from different countries. It based on the joint hypothesis that the prices of the domestic currency are sticky and the disturbances of monetary policy are predominant, which would found the little evidence of a stable relationship between interest rates and exchange rates. It is true that in many cases the sign of the estimated exchange rate and interest rate differential relationship is consistent with the possible predominance of financial market disturbances, but the relationship is not stable enough to be statistically significant. In Quasi reduced form real exchange rate models, examined the real versions of alternative rational expectations monetary models of exchange rate determination. In the nominal rate models, the exchange rate depends on fundamentals such as relative national money supplies, real incomes, short-term interest rates, expected inf lation differentials, and cumulated trade balances. The rationale view for this approach is that the nominal exchange rates poor performance is primarily attributable to money demand disturbances, so it can define the close relationship between there real interest differentials and real exchange rates, because, in the class of monetary models considered here, unanticipated money demand disturbances affect both variables proportionately. Feinberg Seth Kaplan, (1992), evaluate and interacts the real exchange rates index expectations is developed and used to explore the role of determination on domestic producer prices. The fact that time path of the exchange rate will directly affect the input costs, and the price of substitutes strongly. To examine the links between both actual and anticipated movements in the dollar and relative domestic producer prices, it chooses to analyze price responses to real exchange rate changes. The effect is dependent on the nature of substitutability between imports and domestic goods. The major finding is that the period of appreciation and depreciation over the past 10 years to inhibit the pass through in to domestic prices. In depreciation the market share to enjoy the continued good times kept prices other than expected. Warren Bailey Peter Chung, (1995), considers the study that the impact of fluctuations on exchange rates and political risk is on the risks premium and is reflected the individual equity returns. It suggests the factors which is common for emerging market equity, currency and debt markets, and make empirical implications to evaluate corporate and portfolio management. If price levels and exchange rate are significantly volatile and cannot be costly hedged, are adversely affected in the real value of the domestic currency. Some evidence that exchange rate fluctuations are a priced factor in cross sections of stock return converted into a common currency. The purpose of this research is to explore the impact of fluctuations on exchange rates and political risk which is consider on stock process of individual companies from the same country. The extent of measurement is that, which exposure factors explain cross sections of returns on individual securities and industry portfolios. The result suggests that the exchange rates and political risks could be significant in equity markets. The result also suggests that the risk premium can be time varying and not be detected by assuming constantly. This research shows the results that it did not find the evidence of the equity market premiums for the currency and political risk. It complements the importance to attach the exchange rates and political risk in the international finance. J.R. Lothian M.P. Taylor, (1996), examines the real exchange rate behavior, and explains the variations in sample of stationary univariate equations in real exchange rates. It investigates the additional insight in the exchange rates behavior that can be gained by considering the floating rate from the perspective of the data. These issues can be best understood on the subject of real exchange rates stability between the currencies of the major industrialized countries. Some of the pre-float studies support the fairly stable exchange rates in the long run.

Theory of Optimum Currency Areas: The theory of optimum currency areas, which is usually presented the other name called flexible exchange rate system, but it is proponents as a device of depreciation that take the place of unemployment when the balance of payment is deficit and appreciation when it replace inflation when it is surplus. The problem can be exposed and more revealing by defining a currency area within when exchange rates are fixed.
