Socrates s View Of Justice - 1676 Words

â€Å"But when Socrates was busying himself with ethical questions to the complete neglect of nature as a whole, and was seeking in them for the universal and directing the mind for the first time to definitions, Plato, accepting his teaching, came to the conclusion that it applied to something other than the sensible world: the common definition, he reasoned, could not apply to any of the sensible, since they were always changing,† (Guthrie). Socrates was constantly wrapped up in thought about how the mind works, and of course, how and why the mind changes. These ideas strengthened many of the arguments that Socrates makes in Republic books one through seven. Some of these arguments can be modeled in the question: what is justice? In this question, Socrates plays many mind games with those around him and gets them to all change their mind about what their view of justice is and what it truly means. Later on in the books, Socrates describes the perfect city, and exactly how th at relates to the ever-changing mind. This is interesting because it is nothing like the current society most live in, a democracy. Rather, it is based off of a republic form of government using education of those holding power to signify why they have power. In this world, education is everything. Finally, another idea in which Socrates, or rather Plato, discusses in Republic is the idea of pedagogy or, more simply said, education is modern society. Pedagogy is essentially the roots to all otherShow MoreRelatedSocrates Sides with Creon or a1379 Words   |  6 PagesSocrates#8217; Sides With?

Appreciating Exchange Rates Of Australia †Myassignmenthelp.Com

Questions: Why It Is Important To Analyze Both The Long Term And Short-Term Impact On The Businesses? What Other Factors Are There That Are Affecting The Trading And Increasing The Exchange Rate? Why There Is A Need Of Reducing The Exchange Rate When It Is Good For Many Businesses? What Should Be Done To Control The Other Asian Countries? Is The Impact Of The Appreciating Exchange Rate Has Only Negative Affect? Policies Should Only Be Focusing In Lowering The Exchange Rate? How To Develop Policies That Can Help In Improving The Domestic Market? Answers: Introduction In the recent times, Australia has impacted the global market immensely. In the current global financial and economic system, the Australian dollar has a major role. The fluctuating exchange rate affect various business sectors and communities on a global level like importers, exporters, international and domestic investors. The value of Australian dollar currently revolves around 0.75 US dollars. It belongs to the group small commodity currencies but its movement affects the companies differently from other small commodity currencies. This difference and the increasing strength of the Australian dollar over the past decade is raising question the mind of economist and becoming a topic of discussion. The report presented here aims to analyze its impact on the businesses and the communities and a brief research methodology is presented to come on the conclusion of the problem statement. Recommendations for the same is also added to provide some endurance to the topic (Alauddin, 2013). Aim and objectives The Australian dollar has developed drastically in the last decade and this is leading to the increased concern. The high exchange rates of Australia will impact on the trade-exposed sectors of the economy which is a major concern for the trade operators and associates. The report presented here aims to identify the sectors getting affected by it and present a research methodology to find a solution and developing policies to control the exchange rates (Azimi, 2016). The Appreciation of Australian dollar is propitious for some of the groups while its unpleasant for others. The result is quite diverse and extensive since for importers it is good news as the imports become really cheap thus increasing the demand of the products imported. On the other hand, bad news for exporters as the exports becomes very expensive which reduces their international completeness thus fall in demand of Australian exports. Australia is a country that is based on natural resources for maintaining the economic stability in the nation and thus exports are very important part of the economic and financial aspects of the country (Christensen, 2016). The low rate of exports will drastically affect the earning of the people and will reflect in the GDP pf the country and its per capita income. Another group of people getting affected by the rising value of the Australian dollar will be tourist. Australian government has many programs in the process to increase tourism in the country as it brings capital for the country. But with the increased rates the tourists will prefer a destination that is pocket-friendly. The major population of Australia is of the students and there is a huge percentage of students coming from other countries to study in Australia. But the increasing rate of Australian dollar it will become an unfavorable condition because with a high Australian dollar rate, education becomes expensive in Australia. If the dollar rate is low it becomes cheaper for the travelers and students as compared to other global destinations hence a preferred destination (Dean, 2017). Businesses affected Among the major businesses which will be affected by the strong Australian dollar is the investment sector. Both foreign and domestic investors will be affected by the fluctuating rates. This will lead to decline in investment opportunities in Australia. A reduction will be seen on the end of domestic investors particularly who invests primarily in the companies which have large share of sales in export market, reason being strong dollar will decline their profits drastically. Since the high rate of Australian dollar will make the assets in Australia seem more expensive than the assets of other countries hence they will not consider to make any short-term investment in Australia. This will affect the economy of Australia dramatically. The decline in foreign investments will result in decrease in productivity of the country (Haque, Topal and Lilford, 2015). The investment brings in new technology and scope of growth in the country, with diminishing investment, these opportunities will be slump. Among the other sectors, tourism will also be remarkably affected. The tourism industry compromises of both domestic and foreign tourists, the domestic tourists will prefer to travel abroad rather than within Australia since its cheaper for them to travel other countries. Similarly, foreign tourist will even prefer to choose destinations other than Australia since due to the strong dollar rate Australia becomes comparably more expensive destination than other countries. This will even have an adverse effect on the economy of Australia. Tourism Industry has both a direct and indirect impact on the GDP of the country. The direct impacts include consumption of tourists and the increase in employments in this industry, indirectly its associated with lot many other businesses like hotel industry and transport industry. Further indirect association is the employments with in these industries (Jackson, 2009). The export and import industry are the other principal industries to be affected, which has a huge impact on many other industries within and outside the country. The appreciation of Australian dollar can cause a deficit in trade due to multiplying import and contracting exports. Since a strong Australian dollar means high exchange rate between Australian currency and other currencies thus the repercussions are the export commodities seems to have some high rates. This decreases the export especially in agricultural and manufacturing sector. Contrary to this the importable commodity appears to be relatively cheaper, hence increase in import. This ascend is seen predominantly in energy resources. To find a solution to such issues it is important to conduct the research and find a solution that may help the investors, exporters, and other business sectors along with every group of people that is getting affected by the increasing rate of Australian dollar. Symptoms The symptoms that shows that the change in the exchange rates of the Australian dollar and its impact on two business sectors that is tourism and trading sector and the need of research are given below: - The general opinion says that the effect of the appreciating exchange rate of Australia is all positive, but the actual impacts are diverse and extensive. Looking on the short-term basis the appreciating exchange rates allows increased imports that provide easy and cheap products for the citizen of the country. The diverse impact shows on the exports as it gets expensive and traders reduce it. The result will be increased domestic spending on foreign products and that will affect the local manufacturers and other business sectors (Khayat, 2017). The decreased exports will have the reduced investment and earning of foreign capital that will affect the countrys per capita income and in the future the result will the lowering exchange rates of the currency. The appreciating exchange rates will attract investors in the country or it may make them select other options. This is a likely symptom that can be ascertained only after the impact is researched and analyzed on. The decrease in the tourism will affect the major economic section of the country. This is a symptom that demands the research of the matter and finding and developing the policies that will help the country to enhance its good earning source Tourism its galore (Luetkepohl and Milunovich, 2015). Other countries with the lower exchange rate will try to take the advantage of the situation and will try to capture the global market. For example, China is the country that has a stable exchange rates and with low labor cost it attracts a lot of global investors to invest in the country (Marmolejo, 2011). Decision Statement and Research Question Decision statement are the decisions that a company, organization, or researchers take to decide how to further in a situation. To reach on this decision statement, it is important to identify each factor associated with it and for that research on the different attributes are taken (Meng, 2015). The decision statements here should be as follows: There is a need of policies to control the appreciating Australian dollar The domestic market and manufactures should be developed to stand against in the competition against the imported foreign products. Literature review The objective of this research is to broaden the understanding about how the appreciating Australian dollar affects the economic, social and business conditions in the country. The Garton and his associates says that there are many reasons for this appreciation and that includes high terms of the trade, strong economic performance, rising resources prices, less risk of government debts and difference in interest of Australia and other countries Garton et al. (2012). Therefore, there is a need to determines the impact of appreciation on the various groups and businesses. Ashvini Ravimohan also agrees with it and explain the effects and impacts of the appreciating exchange rates on various business sectors. The conditions will dramatically be affected by the rising dollar rate, which will affect the inflation, employment scenarios etc (Ravimohan, 2010). It is required to understand both the short-term and long-term consequences of the appreciation. Further it is required to analyze the other factors which affect the appreciation as the exchange rate even depends on the other trading partners of Australia like Japan and the EU. The appropriate research required to be done by the affecting businesses to sustain the economic changes. Another author Lin says that the difference between the stock prices and the exchange rates are in need of determination to find right policies for the country to develop domestically and globally (Lin, 2012). The three hypotheses that is leading the economists take this research ahead includes: - The appreciation of the Australian dollar is not a temporary phase and it needs be controlled by developing policies. The business sectors getting affected are very high in number to take this as a serious point to research. Australian government is not efficient enough to manage the appreciating exchange rate and GDP of the country parallelly. Ethical issues When it becomes difficult to take the decision due personal and professional beliefs, then it is known as ethical issues. The ethical issues that may be considered while deciding the policies and taking decision are as follows: - The appreciating exchange rates increases the value of the country in the global market then is it ethical to make policies to reduce it? What is important providing goods to citizens at lower prices or making policies to improve the local products and market? Conclusion The increasing Australian dollar value is the sign of prosperity of the country but its impacts are not very satisfying and all positive. There is a need of policies that help in maintaining the exchange rates of the country and help in improving the businesses of the country that are getting negatively affected by the appreciating exchange rates. The research questions and problem statement discussed in the task emphasizes on the increasing need of creating a balance in the exchange rates and various business sectors and communities that are getting affected by the changed exchange rate of Australian dollar. Thus, a proper research will help to achieve on the conclusion and will help in effectively developing the policies. Recommendations Recommendations that can help in finding the solution to above-given problem statement and related research questions are as follows: - The government should take steps to control the exchange rate There is need of developing the domestic business sector of the country to make the economy of the country stronger. The business sectors should take individual surveys to identify the impact of the appreciating exchange rate. The communities getting affected should take questionnaires and surveys to identify initial issues and then develop policies. References Alauddin, M. (2013).

Turtles Favorite Fish Essays - Turtle, Living Fossils,

Turtles Favorite Fish The project I am working on is called "Which Type of Fish do Turtles Prefer to Eat?" I chose this topic because I wanted to see if the size and color of the fish really matter when it comes to the turtle's eating. I also chose this topic because of the fact that I always have greet colored fish left in the tank after I feed my turtles. I am especially interested if the size of the fish matters when the turtles are eating. I say this because when they are eating it looks like they go after a particular type of fish it usually is the bigger fish in the tank. But the main thing I really want to figure out is if it really matters to the turtle. I want to know this because maybe turtles are like other animals in that they might chose the food they eat or maybe they don't care what they eat. Materials The materials I used to conduct my project were very simple. I used two turtles which were my own and I uses a thirty gallon tank to house the turtles used goldfish as the food for my experiment. The goldfish I used varied in size and color. Some of the fish were big and some were of medium or small size. The color of the fish also varied. Some of the fish were orange, white, red, or Gerry used a video camera to record the turtles section of fish. I recorded the activity of the turtles when I was not there to watch them. Some of the other things I used were a feeder to help me monitor what type of fish I was feeding the turtles. Procedure The procedure I used was simple. Every day I would put in different types of fish. One day I would put in big fish with a orange color and the next day I would put in fish that were smaller and that have a different color. I did this for three months. After each feeding period I would record my results. Hypothesis I think that the turtles will eat the fish according to their size. I feel that the big turtle will eat big fish and the smaller turtle will eat the smaller fish. And for the color of the fish I think that the turtles will choose the brighter colored fish because they are easier to see and that the turtle may have an easier time distinguishing it as food instead of a rock or log or something floating in the water. Results The results I had were that the smaller turtle still ate the bigger fish and that the turtles seemed to always eat the brighter colored fish first. Really I think that the turtles really didn't care what size e the fish was but what the really cared about was the color of the fish. I say this because each time I fed them there always seemed to be a lot of gray colored fish left over. The results of my experiment somewhat correlated to my hypothesis in that the color of the fish has an affect on what the turtle will eat. Conclusion The conclusion of my experiment is that the turtles don't really care about the size of the fish, but the turtles really care about the color of the fish. I know this because during my experiment the turtles seemed to favor the orange fish and the always left the gray fish there. Even when there were only gray fish in the tank the turtles still did not choose to eat them. So in conclusion of my experiment the turtles don't really care for size but the turtles really care about the color of the fish. General Information Scientific classification Trachemys Scripta Elegans. Common name Red-Eared Slider or Florida turtle. Geographic distribution This native of the south of the United States is found in many places of the world. It has been introduced by people who bought them as pets to later release them in the wild when they decide they don't want to keep them anymore. This represents a big problem. In southern Europe, for example, the red-eared slider competes for survival against the costume of Europe who is now in danger of extinction. Size It can grow up to 30 cms (11.8 inches). Longevity In the wild it can live about 20 years, but in captivity some specimens have been reported to live

Urban Morphology of Dhaka City Spatial Dynamics of Growing City and the Urban Core Essay Example

Urban Morphology of Dhaka City: Spatial Dynamics of Growing City and the Urban Core Essay Urban Morphology of Dhaka City: Spatial Dynamics of Growing City and the Urban Core Prof. Dr. Farida Nilufar Department of Architecture, Bangladesh University of Engineering and Technology (BUET) Email: [emailprotected] com [Paper presented on the International Seminar on The History, Heritage and Urban Issues of Capital Dhaka, on the occasion of the Celebration of 400 years of the Capital Dhaka, Organized by the Asiatic Society of Bangladesh, 17-19 February 2010. Accepted for Publication of Asiatic Society on the Celebration of 400 years of the Capital Dhaka, Organized by the Asiatic Society of Bangladesh, Accepted in June 2010] ABSTRACT: The fundamental morphological characteristics of Dhaka city is described here from a historical perspective. Since its establishment, Dhaka represents domination of an organic spatial character in general. Here in Dhaka, two dominant urban patterns are conspicuous within the successive stages of growth; they are the historical core or old Dhaka and the later development towards the north, known as new Dhaka. Besides, a few planned additions are also featured in this city. Thus, this study identifies that four major spatial patterns are co-existent in Dhaka; they are indigenous and informal developments; colonial and planned interventions. The essential morphological characteristics of these patterns, which are prevalent in Dhaka, are described here. Major discussion concentrates on the global spatial structure of the organic city and investigates the dynamics of its growth and the characteristics of morphological transformations through the ages.

Thus the spatial dynamics of Dhaka and its core corresponds to a social history which remains as the underlying force behind the spontaneous formation of its morphological structure. . 1. Introduction: The city of Dhaka has arisen more or less spontaneously over four hundred years. In the history, the evolution of Dhaka as a town goes back to the 16th century. With the passage of time the entire city grew in a natural way, although it has some parts which have been deliberately created in the recent past by the designers, albeit in a fragmented way. Its different phases have developed and structured at different historical stages based on the vigour of that particular period of development. Dhaka, the capital city of Bangladesh, has grown from a small Hindu trading centre to a metropolis. Its antiquity can be traced back to 7th century A. D. ; however, Dhaka rose to prominence only after it became the capital of Bengal[1] during the Mughal rule under the Muslims in 1610 A. D. For a long period of its growth Dhaka was confined within the medieval Mughal core. An early impetus in the growth of a new town outside the historic city, however, started in around 1764[2]. In spite of that only after 1906, on the declaration of Dhaka as the capital of the province of East Bengal and Assam, a spectacular development of the city has been manifested in the Ramna green belt outside the historic core in the newer part of Dhaka. Historian Bradely-Birt noted that a modern city has begun to rise. [Bradely-Birt, 1975: 261] This drift of development was impeded several times due to different political and economic reasons. However, after the independence of Bangladesh new Dhaka has experienced a phenomenal growth. Within the successive stages of growth, two dominant urban patterns are conspicuous in Dhaka; they are the historical core or old Dhaka and the later development towards the north, known as new Dhaka. The historic kernel of old Dhaka retains the traditional features it has inherited from the past. The natural endowment of its organic morphology is valued for its ‘indigenous’ urban pattern. The residential neighbourhoods of old Dhaka, locally known as ‘Mohallas’, which were the enclaves of caste or craft groups are considered by many to be a morphological archetype of this historic city. Outside the historic core, the newer part is a post colonial development, thereby sometimes metaphorically understood as a function of modernization. In the newer extensions of Dhaka, similar organic morphological patterns are prevalent which have been spontaneously developed without any rigid planning proposal. In terms of established planning principles the character of these areas is seen as a confused urban sprawl. There remains quite a lot of prejudice attached to these unplanned areas; and they are customarily described as ‘informal’ development. Nevertheless, these new generation organic areas are generally developed according to the aspiration of their inhabitants just like that of the historic city itself. The demarcation of the old and new town was geographically emphasized by the placement of the State Railway line which gave an idea about the existence of the main historic city in the quarters to the south and west of the loop formed by the Railway line. Ahmed, 1986: 99] To some people, to call the historical part old seems to be a general misconception about it; however, there is no doubt about the extensive livability and usability of the older part even in this century, and it is well understood that being a meaningful and living form, despite the loss of official and political patronage, the old city did not fade away but was thrived and enhanced. For this reason it is sometimes claimed that old city is as contemporary as the new city. [Khan, 1982: 1. 1] After traveling around fifty Indian cities including Dhaka in 1915-1919, Sir Patrick Geddes advocated that understanding the past is the first step in planning the present and future. [Spodek, 1993: 256] Geddes further added that The diagnostic survey . . . seeks to unravel the old city’s labyrinth and discern how this has grown up. Though, like all organic growths, this may at first seem confused to our modern eyes, that have for so long been trained to a mechanical order, gradually a higher form of order can be discerned the order of life in development . . In city planning then, we must constantly keep in view the whole city, old and new alike in all its aspects and at all its levels. The transition in an Indian city, from narrow lanes and earthen dwellings to small streets, great streets and buildings of high importance and architectural beauty, forms an inseparably interwoven structure. Once this is understood, the city plan ceases to appear instead as a great chessboard on which the manifold game of life is in active progress. [Geddes, 1919 as in Tyrwhitt 1947: 26-27] The evolutionary layering of urban form and meaning which Geddes uncovered as a town planner needs to be explored in historic studies of Dhaka. This article initially tries to identify the primary spatial patterns existing in Dhaka since its inception. Moreover, it aims to investigate the spatial dynamics of urban growth of Dhaka by analyzing the configuration of the urban grid and the resultant urban form in its historical perspective. It tries to pinpoint how the cumulative process of growth and consolidation has influenced the organic spatial structure of Dhaka. Fig: 1] It also endeavors to reveal the fundamental relation between configuration of space in an organic city like Dhaka and the way that it functions. 3. Urban Spatial Patterns in Dhaka Today’s Dhaka represents a composite form developed through ages. Its fundamental organic spatial homogeneity is interrupted at times by the patches of grid patterns. It is observes that there are five distinctive and co-existent u rban arrangements are prevalent in Dhaka. These can also be marked as ecological units, which are i] the old city ii] Civil Lines iii] New Indigenous or Informal communities; iv] the Planned Schemes and v] the Squatters’ Clusters. The squatters’ clusters are mostly transient in nature. However, the spatial pattern of the other four ecological types is discussed here. [Fig. 2 3] 3. 1 Indigenous Historic Structure Its organic character of the historic part is particularly distinctive with the densely built-up areas in comparison to the looseness of the later developments. Thus, like most Indian towns, the historical spatial structure of old Dhaka remains as the relic of the past. The pattern that exists in the old city is the winding and intricate street network and the walls defining the houses. The streets in the historic part were narrow. They were continuously twisted in and out, and were tortuous to an extreme degree in some places. The dead-end passages sometimes cut deep inside the urban block presenting a series of sharp turns. These were found indiscriminately along both the thoroughfares and the alleys. This pattern is more persistent in old city. However, a few long lines passed through the residential areas, which gave rise to another type of urban pattern e. g. Shankhari Bazaar Road, Tanti Bazaar Road. These were mainly the commercial interfaces of the city; and such areas have no lanes and by lanes as the access are from single bazaar streets. These streets are defined by closely spaced buildings in contrast to the former pattern where buildings are loosely spaced. Thus two distinct urban patterns exist in the old city. [Khan, 1982] However, the urban blocks of the latter type took more usual form of an accumulation of burgage plots whilst that of the former were divided by the dominant system of land holdings into smaller rectangular areas or segments. Fig. 3a] 2. 2. Colonial Interventions Civil lines A general grid pattern with broad traversing streets and rectangular blocks was proposed for the modernization of the historic city of Dhaka by Dr. Henry Charles Cutcliff, a British reformer. A radical engineering approach was needed in order to drive the broad straight streets through the crowded confusion of the city quarters. Although the scheme was not adopted in its entirety, it seems that all the later improvement of Dhaka was essentially based upon it. Ahmed, 1986: 182] In a later period Patrick Geddes was sensitive in dealing with historic areas and emphasized the ameliorative change through ‘conservative surgery’. [Geddes, 1917] Therefore, except in the northern extension of the historic core in and around Ramna area representing an orthogonal grid, the remaining historic city appears as organic. [Fig: 2] Consequently, the colonial city of Dhaka is not that visible as their intervention was limited within the linear civil line development along a few streets and the grid pattern of the Paltan [Cantonment]. Gupta claims that whereas the presidency towns were wholly planned on the grid in Europe, contemporary British Indian towns had only small sections planned, and subsequent growth was by accretion, in an ad hoc manner, by taking in adjacent villages. [Gupta, 1991: 596] However, the civil lines in the sub-continental cities were laid out as the British Precinct in the mid nineteenth century. Minto Road, Hare Road, Bailey Road, and Park Road are such developments in Dhaka outside the historic core. Their arrangement represents a formal and spacious one which is totally different in look from the dense development of the previous time. These were like Victorian suburbs characterized by low-density, horizontal development and broad tree lined roads giving access to a system of large compounds containing spacious single Bungalows in each plot. However, such pattern is being extinguished from the present urban form of Dhaka. 2. 3. New Indigenous Communities Informal Layout Another socio-spatial idiom in Dhaka is that of the upgraded indigenous neighbourhood, such areas like Kalabagan, Kathalbagan, Razabazaar, Mogbazaar, Malibagh etc. [Fig. c] They are labyrinthine mixture of lanes, by-lanes and cul-de-sacks like old Dhaka but wider and less intricate than the older city roads. They seem like the representations of traditional indigenous urban developments in the setting of a modern background. However, the formation of the blocks and main streets mainly followed the proposals of the Master Plan of 1959 and appear as longer and wider lines in the city structure. The inner roads or alleys are again narrow and winding o nes. Mostly they are organic in growth as they generate with the increasing plot division. Land uses are of a mixed type, however residential use gets prominence. The main thoroughfares become the major shopping strips and most buildings are designed to accommodate shops at the ground level. Generally the land use pattern resembles the old city rather than the civil lines. House design combines modern and traditional features in a harmonious blend. They cover the whole plot most of the time leaving narrow strips beside boundary walls as dictated by the planning authority but not like the courtyard houses of the old Dhaka. These popular settlements are very much like the old city development but the planning rules gave them a new look. 2. 4. Planned Schemes Geometric Layout The grid pattern of roads was introduced in the city for the first time in Wari and Gandaria in 1885. The state sponsored planned extensions for the upper classes were contrasted with the unsanctioned, spontaneous, tawdry development in the old city. Comprehensively planned residential areas of Dhanmondi, Gulshan, Banani, Baridhara and Uttara etc. re the successors of this type. Their street layout follows a rigid gridiron pattern with some semicircular arcs. [Fig. 3b] The land formation exerted a little influence on the new development and this why they are found globally to be in some way more logical or imposed upon their surroundings. The high space and service standards and physical designs of these schemes have an aura of Western suburbia, modernity, and status. They essentially follow the civil lines model, though without th e Imperial grandeur. Such planned schemes were generally situated at the fringes when the plans were undertaken; however now a days they are surrounded by the high density low income living due to the increase of population. 3. Spatial Dynamics of Growing City: Urban core and functional pattern in Dhaka Above the levels of technology and economic condition of the population, the patterns of areal expansion and the urban form of Dhaka have been dominated largely by the physical configuration of the landscape in and around the city, particularly the river system and the height of land in relation to flood level. Islam, 1996: 191] Thus the ground plan of Dhaka shows a less systematic form possessing a kind of homogeneity depending on the continued adaptation to the land morphology and also possibly to the culturally derived patterns in the historic core. Thus guided by the natural determinants, however, the demand of its dwellers shaped it as a city of variety. The shifting pattern of land use distribution, mainly that of commercial activities, in Dhaka seems not follow the categories commonly used by the literature of city planning and urbanization for western cities and even specifically for south-east Asian cities. Mollah, 1976: 39] Although it is claimed that the generalized functional growth pattern of Dhaka is concentric around the business districts [Chowdhury, 1981: 15], the character of – Concentric Zones seems not to be applicable here because the phenomena they describe assume consistency and continuity of a feature, whereas Dhaka is characterized by discontinuities of factors and multiplicity of sectors and circuits. Indeed, historians assert that the fundamental source of the life of Dhaka had been determined by political considerations as these have unfolded over time. Ahsan, 1991: 397] In fact, Dhaka faced six major phases of socio-economic and political changes during its evolution. The following part of discussion seeks to understand the morphological changes o f the urban core of spatial structure of Dhaka since historical time by analyzing available maps from 1859 2007 and simulating two previous stages [Pre-mughal and Mughal Period]. Two maps are available from Pakistan period; one is of 1952 at the inception of Pakistan with the indigenous city and the colonial development seen as a whole; and the other is of 1960. Besides, four maps are considered from the Bangladesh era [Maps of 1973, 1987 and 1995 are prepared by the Survey of Bangladesh’, and Map of 2007 is prepared by DCC]. This study tries to pinpoint how the cumulative process of growth and consolidation has influenced the spatial structure of Dhaka at a global scale by using the tool of Space Syntax'[3] as developed by AAS, Bartlett, UCL, London. Here the spatial structure of Dhaka city is modeled with axial lines following the conception of Space Syntax and the axial maps[4] are analyzed with Depthmap[5] to identify the integration core[6]of the spatial structure of the whole city. The brief historical overview has been highlighted the fact that as Dhaka has grown in size, scale and extent, and the distribution of urban functions has evolved and changed according to the dictates of political and commercial considerations. However, it is not clear whether these changes were arbitrary, or whether there was any logic to the pattern of relocation. In what follows, integration analysis by the Space Syntax will explore the way in which urban growth brought about changes in the configuration of the urban grid, and hence in the distribution of integration throughout the city. These purely configurational changes are considered in relation to the changing pattern of urban functions, to see if they relate to one another in a systematic way. This study tries to explore the fundamental relation between the configuration of space in Dhaka and the way that it functions. Finally, it determines the spatial structure of Dhakas urban core and the process of its transformation through ages. 3. 1. Pre-Mughal Hindu Core of Dhaka [before 1608]: Dhaka was a small Hindu trading centre in Pre-Mughal time. As revealed from cartographic evidences the area lying to the east, north-east and south-east f Babur Bazaar going up to the Dholai River on the northern bank of the Buriganga seems to face the old town. It is now thought that Dhaka was confined between the Dholai Canal [on the north east boundary of the city] and the Buriganga River from its inception until 1608, which ushered in the Mughal period. The oldest city consisted of a few market centers like Lakshmi Bazaar, B angla Bazaar, Shankhari Bazaar, Tanti Bazaar etc. along with a few localities of craftsman and businessmen like Patua-toli, Kumar-toli etc. [Dani, 1956: 7] The centre is thought to have been near the Bangla Bazaar. According to Dani, the main business area was in Sadar Ghat and Victoria Park, which had extended upto Nawabpur Road in later part of 15th century [Ahsan, 1991:397- 398]. No detailed maps from this period are available on which to develop an axial model. However, in order to remake the picture of the past, a reconstruction of the Hindu core has been developed here from the oldest detailed map of Dhaka in 1859 [prepared by Rennell]. [7] The spatial analysis of axial map shows that in the pre-Mughal Dhaka, the global integration core was formed with Nawabpur Road-Johnson Road leading towards the Sadar Ghat. It also touched part of Islampur Road, Bangshal Road and Shankhari Bazar Road. This loop like core coincided with the functional heart of the city as described by Dani. [Fig. 4] 3. 2. Mughal Dhaka [1608- 1764]: Dhaka rose to prominence only after it became the capital of Bengal during the Mughal rule in 1610 AD. [Bhattacharya, 1935: 36-63] The then ‘New Dhaka’ was inaugurated by Islam Khan with the establishment of Lalbagh Fort in 1679, Chandnighat and the Chawk [the market place beside the old fort at present Central Jail]; and it continued to grow under the subsequent Mughal Subaders until 1717. Dani, 1956: 31] According to Manrique, a visitor to the city, in 1640 the city stretched for 4. 5 miles along the Buriganga river with a population of about 200 thousand [excluding the Europeans and the visitors] [Taifoor, 1956: 15] which raised to 9,00,000 in 1700. During this period, the needs of administration and defence coupled with flourishing commercial activities led to Dhaka’s growth, and from a suburban town Dhaka became a metropolis. [Khan Atiquallah, 1965: 2-6] In time, Dhaka grew beyond the limit of the Dholai Canal; and the Mughal Dhaka had encompassed the pre-Mughal core. [Fig. ] In 1640 the expansion to the west [to Maneswar and Hazaribagh] and the north [up to Phulbaria, on the fringe of the Ramna area] was significant; besides it’s eastern limit was up to Narandiu [Narinda] [Manrique as in Chowdhury and Faruqui, 1991: 48] Bradley-Birt described as away beyond for fourteen miles, the city stretched as far as Tongi, a vast labyrinth of streets and villages, the camps of armies and all that followed in their terrain [Bradley-Birt, 1975: 159]. However, the Mughal ruins identified the extension of the Mughal city mainly to the west of the Fort and following the river bank. The expansion occurred with the Old Fort in the centre. In this growth of Mughal Dhaka the general characteristics of a Mughal city are noticeable. The Fort served as the nerve centre of the city, and the adjacent market places and the surrounding mohallas growing out of the residential needs follow the well established pattern with winding roads. The areas to the south and south-west of the Fort up to the river bank grew mainly as commercial areas and the areas to the north and north- east grew as residential areas. Chowdhury Faruqui, 1991: 48] The Chawk with the mosque was the main market place of Mughal Dhaka and the river front was transformed into the main commercial area. However, the older part of the city also gained importance by the establishment of European factories in the vicinity of Babur Bazaar and Bangla Bazaar. [Ahsan, 1991: 398] There were two principal roads/thoroughfares in the city. One running parallel to the river from Victoria park to the western fringe of th e city and other ran from the park to Tejgaon[8]. The glory of Dhaka came to an end by the early part of the 18th century with the shifting of the provincial capital from Dhaka to Murshidabad in 1717. In this period the activities of the European traders increased. So the life of Dhaka city was still thriving and it continued in its earlier setting without any farther expansion. [Chowdhury Faruqui, 1991: 52] In the absence of a detailed map of Mughal Dhaka, a second reconstruction was developed during this research based on a combination of historical documents and the findings of other researchers who have tried to define the boundary of the Mughal capital, Dhaka. It too is based on the original map of 1859. The spatial analysis of Mughal Dhaka produced a global integration core along Bangshal Road which was linked up with Nawabpur Road. Thus, in the Mughal period, the integration core lay on the northern periphery of the city seemingly as an extension of the pre-Mughal global core. The historical statement that the Fort served as the nerve centre of the city does not fit with the syntactic analysis; rather the global integration core connected the Mughal centre [the Chawk and the old fort] with the Hindu core [Bangla Bazaar surrounding the present Court House area]. The integration core therefore connected the administrative and commercial foci as described earlier by historians, but seems to leave out the city life on the river side. When the river was also considered as a route, and connected to the street system through its ports the global core has a dramatic shift from the northern periphery towards the river front which reveals a probable importance of the river on the life of Dhaka at that period. [Nilufar, 1997:111] However, the spatial analysis reveals that the integration core of Mughal Dhaka was an extension of the pre-Mughal core. It also connected the Mughal and pre-Mughal functional cores with bazaar streets. However, Islampur Road had not yet gained spatial importance globally. [Nilufar, 1997: 113] 3. 3 Dhaka in the Pre-Colonial Period- Rule of the East India Company [1764-1857]: With the fall of the Mughal Empire in 1707 Dhaka faced a serious decline in economy, population and administrative importance which caused the subsequent contraction of urban area. An English trading company attained political domination and took over the control of Dhaka city in 1764. Most of the commercial activities which survived were carried out in the enclosure of Chawk [Ahsan, 1991: 401]; and the old fort and its surroundings remained the heart of the city where all the central and provincial offices were also located. [Ahmed, 1986: 130-143] In 1800 population of Dhaka declined to 200 thousands, like that of 160 years back. According to Rennell the city was four miles long and two and half miles wide in 1793 which reduced to three miles in length and one and half mile in width in 1814. Mamun, 1990: 49] In 1859, Rennell prepared a map of Dhaka city as extending from Narayanganj to Iron Bridge and from the Buriganga river to Nimtali Kothi [present Asiatic Society]. In this map the jungles indicate a decline in population and a subsequent contraction of urban area. In fact the decline in economy, population and administrative importance brought about shrinkage in the area of Dhaka city. [Fig 6] The axial analysis of the spatial system of 1859s Dhaka depicted th at the city had densely inhabited areas in the pre-Mughal Hindu core extending towards the Mughal centre [the Chawk]. At this period, most of the areas to the west of the Mughal centre were segregated. The global integration core took the shape of a loop connecting the pre-Mughal global core to the Chawk, and also leading towards north [in Purana Paltan area] thus reaching out towards the extending city. The river side also got importance in the spatial structure. This phase might be called the period of unification, when the pre-Mughal and Mughal centres were joined, and projected outwards in the direction of the future city and the river. The most integrated line was Bangshal Road, and the next was Nawabpur Road, the two bazaar streets. Thus, the global integration core largely coincided with the commercial interface which was the focus of the city life. Again, the administrative areas were also linked to the core at its southern edge. In order to avoid the influence of the uninhabited garden areas in the north, the built-up areas of the 1859 spatial structure were analyzed separately but no changes occurred in the picture of integration with respect to Islampur Road. Fig. 8] This might indicate that this bazaar street could not gain any significant global importance in the city structure around 1859. However, Islampur Road and a number of bazaar streets were locally important. [Nilufar, 1997: 112] 3. 4. British Colonization of Dhaka [1858-1947]: The old Mughal town did not expand with British rule, but it underwent a vast physical renewal following no definite plan. This transformed the medieval Dhaka into a modern c ity with metalled roads, open spaces, street lights and piped water supply. Ahmed, 1986:130-143] The State Railway was opened in 1885-86 and the rail line was laid through the city to connect it with areas outside Dhaka. The placement of the railway line gives an idea about the existence of the main city to the quarters south and west of the loop formed by the railway line. However, the building of a new town started beyond the rail road in Ramna. [Ahsan, 1991: 401] However, most of the residential quarters were within the historic core; and the river front and the area near the Victoria Park was a prized location for high class residents. Islam, 1996: 14] An irregular road pattern was prevalent to the south in the historic core; while the grid pattern of roads was introduced in the city for the first time in 1885 in Wari and Gandaria as planned residential areas. Hazaribagh, Nawabganj areas in the western quarter of the city, were developed in the same period as industrial areas. [ Chowdhury Faruqui, 1991: 54-55] Civil lines were also added beyond the city limit in 1906. The British crown shifted the administrative centre from the old fort area, and new buildings were constructed on a new site near Victoria Park, on the present site of the Court House. Ahmed, 1986: 141] From Mughal time the Chawk Bazaar had been the main centre of the citys trade and commerce in Dhaka, and it remained so after 1859. The business areas during this period extended towards the north by way of the Nawabpur Road into Ramna to serve the British bureaucrats who lived in the new town. [Ahsan, 1991: 402] In 1905, in the middle stage of the British era, Bengal was divided and Dhaka was chosen as the capital of the eastern part. [Islam, 1991: 197] Another significant incidence to the city of Dhaka was the foundation of Dhaka University in the vicinity of Ramna in 1921. Early records of the East India Company [1786] describe the city boundary as: Buriganga in south, Tongi in the north, Mirpur in the west and Postogola in the east. [Karim, 1964: 37] Although it was the overall limit of the city by the end of the 18th century, the area lying to the north of Mir Jumlas gate [near Ramna] was very sparsely populated. According to Rennell, the population decline which started from 1764 reached its lowest ebb in 1867 when the population reduced to 51,636. Since 1872 the population recorded a continuous growth. The spatial pattern was changed in this phase by the extensions at the periphery and by an increase in destiny within the built up areas with densely packed, short and tree-like broken lines. In the map of 1916[9], the global integration core was pushed towards the north near the Ramna Garden where the newly-planned, relatively orthogonal grid was being introduced. Thus the most integrated lines were in the area where the old [pre-British] part met the new [developed in the British era], which indicated a change in the social life of the city during the colonial period. [Fig. ] In order to have an idea about the life of the people who were living in the densely built up areas of the old city, the built up area in 1916 was analyzed syntactically without the colonial additions. [Fig . 8] In this analysis, the higher global integration values were attained by the bazaar streets, Islampur Road and Nawabpur Road. Thus the most integrated lines extended parallel to the river, forming a lin ear integration core which coincided with the functional core of the city. It seems that Islampur Road attained its spatial significance in the old city only from the colonial era. . 5. Dhaka as the Capital of Pakistan [1947-1971]: In 1947, the British Colony achieved its independence after two hundred years of colonization and Dhaka attained the status of the provincial capital of the East Pakistan. Unlike many colonial cities in India, the colonial influence on Dhaka could not be claimed as substantial. The overall expansion of the city began from 1947. [Huq, 1991: 428] Administrative, commercial and residential needs caused an influx of people and it resulted in a massive growth of the city. The city expanded mainly towards the north. Dhanmondi area, as previously adorned with paddy fields, lying towards the north-west fringe of Dhaka turned into a residential area after 1955. The Mirpur Road formed an axis and high lands on either side were occupied up to Mohammadpur and Mirpur. The high land available in north-east and north-west of Ramna within different pockets between the previously developed areas like Purana Paltan to Naya Paltan, Eskaton to Mogbazaar, Siddheswari and Kakrail to Kamlapur through Razarbagh and Santinager, Segun Bagicha all came to be occupied mostly by residential use. All these happened without any formal planning. Then the government founded Dacca Improvement Trust [DIT] in 1956 and started planning in a piecemeal manner: industrial district in Tejgaon, New Market in Azimpur, staff housing in Motijheel, high class residential area in Dhanmondi. However, at this stage there was no plan for the future growth. In the meanwhile Dhaka was becoming more and more unmanageable. So a Master Plan was eventually prepared by consultants in 1959 on behalf of DIT. 10] The DIT developed Gulshan model town

Abortion Essays (1825 words) - Fertility, RTT, Abortion, Free Essays

Abortion Essays (1825 words) - Fertility, RTT, Abortion, Free Essays Abortion Abortion In Roman times, abortion and the destruction of unwanted children was permissible, but as out civilization has aged, it seems that such acts were no longer acceptable by rational human beings, so that in 1948, Canada along with most other nations in the world signed a declaration of the United Nations promising every human being the right to life. The World Medical Association meeting in Geneve at the same time, stated that the utmost respect for human life was to be from the moment of conception. This declaration was re-affirmed when the World Medical Association met in Oslo in 1970. Should we go backwards in our concern for the life of an individual human being? The unborn human is still a human life and not all the wishful thinking of those advocating repeal of abortion laws, can alter this. Those of us who would seek to protect the human who is still to small to cry aloud for it's own protection, have been accused of having a 19th Century approach to life in the last third of the 20th Century. But who in reality is using arguments of a bygone Century? It is an incontrovertible fact of biological science - Make no Mistake - that from the moment of conception, a new human life has been created. Only those who allow their emotional passion to overide their knowledge, can deny it: only those who are irrational or ignorant of science, doubt that when a human sperm fertilizes a human ovum a new human being is created. A new human being who carries genes in its cells that make that human being uniquely different from any and other human being and yet, undeniably a member, as we all are, of the great human family. All the fetus needs to grow into a babe, a child, an old man, is time, nutrition and a suitable environment. It is determined at that very moment of conception whether the baby will be a boy or a girl; which of his parents he will look like; what blood type he will have. His whole heritage is forever fixed. Look at a human being 8 weeks after conception and you, yes every person here who can tell the difference between a man and a women, will be able to look at the fetus and tell me whether it is a baby boy or a girl. No, a fetus is not just another part of a women's body like an appendix or appendage. These appendages, these perfectly formed tiny feel belong to a 10 week developed baby, not to his or her mother. The fetus is distinct and different and has it's own heart beat. Do you know that the fetus' heart started beating just 18 days after a new life was created, beating before the mother even knew she was pregnant? By 3 months of pregnancy the developing baby is just small enough to be help in the palm of a man's hand but look closely at this 3 month old fetus. All his organs are formed and all his systems working. He swims, he grasps a pointer, he moves freely, he excretes urine. If you inject a sweet solution into the water around him, he will swallaw because he likes the taste. Inject a bitter solution and he will quit swallowing because he does not like the taste. By 16 weeks it is obvious to all, except those who have eyes but deliberately do not see, that this is a young human being. Who chooses life or death for this little one because abortion is the taking of a human life? This fact is undeniable; however much of the members of the Women's Liberation Movement, the new Feminists, Dr. Henry Morgentaler or the Canadian Medical Association President feel about it, does not alter the fact of the matter. An incontrovertible fact that cannot change as feelings change. If abortion is undeniably the taking of human life and yet sincere misguided people feel that it should be just a personal matter between a women and the doctor, there seems to be 2 choices open to them. (1) That they would believe that other acts of destruction of human beings such as infanticide

Interview with Dr. Michael Winters Essay Example | Topics and Well Written Essays - 1000 words

Interview with Dr. Michael Winters - Essay Example As a licensed practitioner of and a firm believer in the merits of logotherapy, the search for and discovery of meaning plays a significant role in Dr. Winters' professional, clinical, teaching, and research activities.The search for meaning has had a strong basis in Dr. Winters' background, as reflected by his two choices for a college major: Theater or Psychology. Broadway's loss was psychology's gain, as he found the search for meaning more lucrative and challenging than, in a sense, its interpretation. After undergraduate and Masteral studies at Purdue, he went to Tennessee for his doctorate at the University of Memphis in 1991.However, it was not until two years ago (in 2005) that he embraced logotherapy, which is based on Frankl's insights on the beneficial psychological effects of the search for and discovery of meaning in human experience (Frankl, 1984/19871998). Frankl has had a substantial impact on Dr. Winters' life and profession, and logotherapy research has become a hug e part of his academic and clinical practice. As a counseling strategy, he uses logotherapy, which fits with the question that he asks every time he faces any of his clients: "how do I help this person to help him/herself move forward" (Winters, 2007)Dr. Winters' extensive experience, however, does not limit his counseling strategy to logotherapy. ... Among college students, though, Dr. Winters addresses more faith-based issues in search of solutions. Dr. Winters is also an expert on clinical depression, and a considerable amount of time was spent during the interview discussing this topic. We started by discussing the symptoms, which are primarily anxiety, pessimism, and lethargy. When asked what the causes of depression are, he paused for several seconds before answering: "anything". Depression is a chemical reaction that affects the mind, and this can be triggered by anxieties over relationships (romantic or otherwise), emotional or physical or psychological trauma. Among young people, common triggers of depression are issues with parents, relationships, or friends, or the search for and development of individual identity. If there is what he could call a master variable that helps one to avoid depression, it is the value of social networking. He noted from his clinical and professional experience that people who know how to get the most out of their social relationships with family, friends, and a special other are farthest away from depression. I guess that an important consideration here is the sense of security that a person feels, allowing him/her to maintain their identity in social relationships, free of false expectations and desires to be what they are not. As Dr. Winters shares with his clients, if they are not happy and truly getting their needs in their relationships, then they should either end it or fix it, working on the issues unless there is violence. He encourages his clients in a depression to move beyond a definition of love that is based on what they could get out of a relationship to one

Management Information System. (Position Paper) Assignment

Management Information System. (Position Paper) - Assignment Example Voice via internet protocol (VOIP) telephones offer high-tech means for employees to connect (Legge, 1991). When it comes to inventory management, Syndicate Technological Company has adopted the urgency to ensure that there is adequate stock to meet demand without spending in more than they need. Systems for managing inventory that track the measure of each item a company keeps, triggering an order of extra stock when the quantities goes below a certain amount. These systems work effectively when the inventory management system is linked to a point-of-sale (POS) system. The POS system ensures a removal of item from the inventory count, the moment an item is sold, creating a closed information loop between all departments. Syndicate Technological Company keeps digital forms of documents on servers and other mass storage devices like flash disk, DVD’s among others. These documents become instantaneously accessible to everybody in the company, irrespective of their geographical locality. Syndicate Technological Company is able to store and preserve an incredible amount of chronological data economically, and employees profit from instantaneous access to the documents they want. Storage of data and information is only an advantage if that data can be used successfully. Syndicate Technological Company use that information part of their strategic design procedure as well as the tactical implementation of that approach (Sarngadharan & Minimol, 2010). Management Information Systems (MIS) aid Syndicate Technological Company to follow up on sales data, expenditures and yield levels. The statistics can be used to track viability over time, capitalize return on investment and find areas to improve. Syndicate Technological Company is adopting information technology to enhance its design and management of customer affiliations. Consumer Relationship Management (CRM) systems records every dealings a business has with a consumer, so that a more

Revisions of Foundations of the Development and Functions of Police Assignment

Revisions of Foundations of the Development and Functions of Police - Assignment Example The political policing era of policing embraced the watch-man style, which embodied police discretion, and control rather than prevention a system, which is distant from society (Ken, 2009). In terms of discretion, police chose whom to serve and protect at their judgment with reference to politicians who had immense control over them. The approach of dealing with crime was often questioned because of its reactive nature. The control of crime was based on controlling rather than prevention and this hugely led to crime escalation (Ken, 2009). Second was the legalistic style, which made law enforcement the only concern of the police at the expense of social problems; by advocating only for the enforcement of the law to the letter. Politicians enacted several Legislations to establish full-time control over the police. A good example is the 1844 law in New York City that aimed at putting police under the control of city politicians and the government (Ken, 2009). Such laws disregarded public view, as they were the preserve of the political class. The police had no interest at all about the social problems in the country. The main agenda was to enforce and implement the law to the letter. Finally was the service style whereby police conceptualized themselves as helpers of the country when crime or war occurred. Service delivery was considered as a favor to the society rather than an obligation. It is often well-known as the systematic policing practice whose mandate was to reform the political-oriented police practice (Ken, 2009). It embraced the three styles but implemented each of them completely different from the political approach. Discretion exercised early was limited by far. The police schedule became standardized, as officers were now required to enforce the law and make arrests based on the crime committed lieu of the political power-play (Ken, 2009). More efforts were evoked to prevent crime rather making injunctions only after crime

Fiber optics and its applications

Fiber optics and its applications INTRODUCTION Nothing in the world gives us more power and confidence than having information. The ability to communicate information is essential to achieve the successful advancement of humankind. Transmission of information is imperative to the expansion of our horizons. What does this all have to do with fiber optics? This research paper will cover the basis of fiber optics in terms of its transmission, communication, origin, uses and applications. Fiber optics transports light in a very directional way. Light is focused into and guided through a cylindrical glass fiber. Inside the core of the fiber light bounces back and forth at angles to the side walls, making its way to the end of the fiber where it eventually escapes. The light does not escape through the side walls because of total internal reflection. Why is fiber optics so important? Besides being a flexible conduit that is used to illuminate microscopic objects, fiber optics can also transmit information similarly to the way a copper wire can transmit electricity. However, copper transmits only a few million electrical pulses per second, compared to an optical fiber that carries up to a 20 billion light pulses per second. This means telephone, cable and computer companies can handle huge amounts of data transfers at once, much more than conventional wires can carry. Fiber optic cable was developed because of the incredible increase in the quantity of data over the past 20 years. Without fiber optic cable, the modern Internet and World Wide Web would not be possible. WHAT IS FIBER OPTICS? Fiber optics is extremely thin strands of purified glass that carry information from one point to another in the form of light. Unlike copper wire, fiber optics does not use electricity during transmission. Optical fibers can be either glass or plastic tubing capable of transmitting light, which is then converted into sound, speech or information. Fiber optic cables transmit a digital signal via pulses of light through the very thin strands of glass. A basic fiber optic system consists of: a transmitting device, which generates the light signal, an optical fiber cable, which carries the light, and a receiver, which accepts the light signal that was transmitted. A fiber optic strand is about the thickness of a human hair, about 120 micrometers in diameter and can carry as many as 20 billion light pulses per second. The fibers are bundled together to form optical bundles, which transmit the light signals over long distances up to 50 km without the need for repeaters. Each optic fiber is made up of three main parts: The core or the centre of the optical fiber is a very thin strand of glass that carries the light signal. The cladding is the optical material which reflects the light signals back into the core. This prevents the light from escaping and allows it to travel through the fiber. The outside jacket or buffer coating is made of a plastic material that protects the optical fiber from any moisture, corrosion and external damage. There are only two types of fiber optic cable: Glass fibers, which are more common, because they allow longer distance transmission and they are more efficient. Plastic optical fibbers are used in less technical applications and are normally used in very short-length transmissions. HOW ARE OPTICAL FIBERS MADE? Optical fibers are made of very pure glass. The glass core or centre is made of silica and is purified to minimise the loss of signal. It then gets coated to protect the fibers and to contain the light signals. The light signals carried by the optical cable consist of electrical signals that have been converted or changed into light energy. The following process is followed to manufacture the optical fibers: The Manufacturing of the Preform Blank The silica must first be purified before it can be spun into glass fibers. This process takes a long time and the silica is heated to very high temperatures and then distilled to purification. The sand is heated to a temperature that will change the silica into a gaseous state. The silica will then be combined with other materials called dopants, which will react with the silica (in its gaseous state) to form the fibers. All the solid impurities are removed and the gas is cooled to form the fiber material. A process called modified chemical vapour deposition (MCVD) is used to change the glass into the preform blank. During this process oxygen is bubbled through solutions of silicon chloride (SiCl4), germanium chloride (GeCl4) and other chemicals. The gas vapours are channelled to the inside of a synthetic silica quartz tube in a special lathe to form the cladding. While the lathe rotates a burning flame is moved back and forth on the outside of the tube. The extreme heat from the burner causes the following: The silicon and the germanium react with oxygen to form silicon dioxide (SiO2) and germanium dioxide (GeO2). The silicon dioxide and the germanium dioxide settles on the inside of the tube and it fuses together to form glass. The lathe turns continuously to allow the preform blank to be coated evenly. To maintain the purity of the glass a corrosion resistant plastic is used to accurately control the flow and the structure of the mixture. This process of manufacturing the preform blank takes a couple of hours. The preform blank is cooled and is inspected for quality through an inspection and control process. Drawing fibers from the Preform Blank After testing the preform, it is placed into a fiber drawing tower. The preform blank gets lowered into a furnace and is heated between 1,900 °C to 2,200 °C until the tip starts to melt an a molten blob starts to fall down. As it drops down, it cools and forms a strand. This strand is pulled through a sequence of coating cups (buffer applicators) and curing ovens using ultraviolet light, and then coiled onto a tractor-controlled reel. This process is accurately controlled using a laser micrometer to measure the thickness of the fiber. This information is then sent back to the tractor mechanism. The tractor mechanism pulls the fibers at a rate of 10 to 20m/sec and the finished product is wound onto a spool. A spool can contain more than 2,2km of optical fiber Testing the Finished Optical Fiber Once the optical fiber is manufactured it goes through a process of testing. The following tests are done: Tensile strength The fibers must withstand 100,000 lb/in2 or more Refractive index profile Determine that the core diameter, cladding dimensions and coating diameter are uniform. Screen also for optical defects. Attenuation Determine the extent that light signals of various wavelengths degrade or reduce over certain distances. Information carrying capacity (bandwidth) the number of signals that can be carried at one time (multi-mode fibers) Chromatic dispersion Spread of various wavelengths of light through the core, this is very important for bandwidth. Operating temperature/humidity range Determines the temperature and humidity that the fiber can withstand. Ability to conduct light underwater Important for undersea cables Once t ­he fibers have passed the quality control process, they are sold to telephone companies, cable companies and network providers. Currently many companies are replacing their old copper-wire-based systems with new fiber-optic-based systems to improve speed, capacity and clarity. TYPES OF OPTICAL FIBERS There are two types of optical fibers: Single Mode Fiber Single mode fibers transmit a single data stream. The core of the glass fiber is much finer than in multi-mode fibers. Light thus travels parallel to the axis, creating little pulse dispersion. Data transmission modes are higher, and the distances that single mode fiber can cover can be over 50 times longer than multi-mode fibers. Telephone and cable television networks install millions of kilometers of this fiber every year. Multi-Mode Fiber Multi-mode fibers allow different data streams to be sent simultaneously over a particular fiber. The glass fiber has a slightly larger diameter to allow light to be sent through the fiber at different angles. An LED or laser light source is used in the 50 micron and 62.5 micron fiber optic cables. They are also used in the same networking applications. The main difference between the two is that 50 micron fiber can support 3 times the bandwidth of 62.5 micron fiber. The 50 micron fiber also supports longer cable runs than 62.5 micron cable. Simplex cable consists of only one single fiber optic strand. The data can only be transmitted in one direction. The duplex cable is made up of two fiber optic strands that run side-by-side. One strand runs from transmit to receive and the other strand joins receive to transmit. This allows communication in both directions (bi-directional) between devices. Some optical fibers can be made from plastic. These fibers have a large core (0.04 inches or 1 mm diameter) and transmit visible red light (wavelength = 650 nm) from LEDs. Due to their inferior optical properties, plastic fiber optic (POF) strands and cables are not suitable for extended data transmission. HOW DOES A FIBER OPTIC CABLE WORK? Traditionally when we sent data transmissions over copper cables we transmit electrons over a copper conductor. Fiber optic cables transmit a digital signal via pulses of light through a very thin strand of glass. The fiber strands are extremely thin, not much thicker than a human hair. The basic fiber optic transmission system consists of three basic components: Transmitter fiber optic cable receiver A transmitter is connected to the one end of the fiber cable. Electronic pulses are converted by the transmitter into light pulses and the optical signal gets sent through the fiber cable. A receiver on the other end decodes the optical signal into digital pulses. The core of the cable is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable. This is called total internal reflection. When light is sent through the core of a fiber optic cable, the light constantly bounces off the cladding, which is highly reflective, like a mirror-lined wall. The cladding does not absorb any light allowing complete internal reflection and allowing the light to travel far distances without losing its intensity. The discovery of lasers influenced the development of fiber optics. Lasers and LEDs can generate an enormous amount of light in a very small area, which can successfully used in fiber optics. Laser diodes are complex semiconductors that convert an electrical current into light. The process of converting the electrical signal into light is far more efficient because it generates less heat than an ordinary light bulb. Reasons for using laser diodes in fiber optics: laser diodes are very small laser diodes are highly reliable and have a long life laser diodes have high radiance laser diodes emit light into a very small area laser diodes can be turned on and off at very high speeds ADVANTAGES OF FIBER OPTICS The use of fiber optics is fast becoming the medium of choice for telecommunication systems, television transmission and data networks. Fiber optic cables have a multitude of advantages and benefits over the more traditional methods of information systems, such as copper or coaxial cables. Speed One of the greatest benefits to using fiber optic systems is the capacity and speed of such a system. Light travels faster than an electrical system which allows faster delivery and reception of information. Fiber optic cables also have a much higher capacity for bandwidth than the more traditional copper cables. Immunity to electromagnetic interference Coaxial cables have a tendency for electromagnetic interference, which renders them less effective. Fiber optics is not affected by external electrical signals, because the data is transmitted with light. Security Optical systems are more secure than traditional mediums. Electromagnetic interference causes coaxial cables to leak information. Optical fiber makes it impossible to remotely detect the signal being transmitted within the cable. The only way to do so is by actually accessing the optical fiber itself. Accessing the fiber requires intervention that is easily detectable by security surveillance. These circumstances make fiber extremely attractive to governments, banks and companies requiring increased security of data. Fire prevention Copper wire transmission can generate sparks, causing shortages and even fire. Because fiber optical strands use light instead of electricity to carry signals, the chance of an electrical fire is eliminated. This makes fiber optics an exceptionally safe form of wiring and one of the safest forms of data transmission. Data signalling Fiber optic systems are much more effective than coaxial or copper systems, because there is minimal loss of data. This can be credited to the design of optical fibers, because of the principle of total internal reflection. The cladding increases the effectiveness of data transmission significantly. There is no crosstalk between cables, e.g. telephone signals from overseas using a signal bounced off a communications satellite, will result in an echo being heard. With undersea fiber optic cables, you have a direct connection with no echoes. Unlike electrical signals in copper wires the light signals from one fiber do not interfere with those of other fibers in the same cable. This means clearer phone conversations or TV reception. Less expensive Several kilometers of optical cable can be made far cheaper than equivalent lengths of copper wire. Service, such as the internet is often cheaper because fiber optic signals stay strong longer, requiring less power over time to transmit signals than copper-wire systems, which need high-voltage transmitters. Large Bandwidth, Light Weight and Small Diameter Modern applications require increased amounts of bandwidth or data capacity, fiber optics can carry much larger bandwidth through a much smaller cable and they arent prone to the loss of information. With the rapid increase of bandwidth demand, fiber optics will continue to play a vital role in the long-term success of telecommunications. Space constraints of many end-users are easily overcome because new cabling can be installed within existing duct systems. The relatively small diameter and light weight of optical cables makes such installations easy and practical. Easy Installation and Upgrades Long lengths of optical cable make installation much easier and less expensive. Fiber optic cables can be installed with the same equipment that is used to install copper and coaxial cables. Long Distance Signal Transmission The low attenuation and superior signal capacity found in optical systems allow much longer intervals of signal transmission than metallic-based systems. Metal based systems require signal repeaters to perform satisfactory. Fiber optic cables can transmit over 100km with no active or passive processing. Even greater distances are being investigated for the future. To use fiber optics in data systems have proven to be a far better alternative to copper wire and coaxial cables. As new technologies are developed, transmission will become even more efficient, assuring the expansion of telecommunication, television and data network industries. DISADVANTAGES OF FIBER OPTICS Despite the many advantages of fiber optic systems, there are some disadvantages. The relative new technology of fiber optic makes the components expensive. Fiber optic transmitters and receivers are still somewhat expensive compared to electrical components. The absence of standardisation in the industry has also limited the acceptance of fiber optics. Many industries are more comfortable with the use of electrical systems and are reluctant to switch to fiber optics. The cost to install fiber optic systems is falling because of an increase in the use of fiber optic technology. As more information about fiber optics is made available to educate managers and technicians, the use of fiber optics in the industry will increase over time. The advantages and the need for more capacity and information will also increase the use of fiber optics. APPLICATIONS OF FIBER OPTICS As the popularity of optical fibers continue to grow, so does their applications and practical uses. Fiber optic cables became more and more popular in a variety of industries and applications. Communications / Data Storage Since fiber optics are resistant to electronic noise, fiber optics has made significant advances in the field of communications. The use of light as its source of data transmission has improved the sound quality in voice communications. It is also being used for transmitting and receiving purposes. Military Optical systems offer more security than traditional metal-based systems. The magnetic interference allows the leak of information in the coaxial cables. Fiber optics is not sensitive to electrical interference; therefore fiber optics is suitable for military application and communications, where signal quality and security of data transmission are important. The increased interest of the military in this technology caused the development of stronger fibers, tactical cables and high quality components. It was also applied in more varied areas such as hydrophones for seismic and SONAR, aircrafts, submarines and other underwater applications. Medical Fiber optic are used as light guides, imaging tools and as lasers for surgeries. Another popular use of fiber-optic cable is in an endoscope, which is a diagnostic instrument that enables users to see through small holes in the body. Medical endoscopes are used for minimally invasive exploratory or surgical procedures. Fiber optics is also used in bronchoscopes and laparoscopes. All versions of endoscopes look like a long thin tube, with a lens or camera at one end through which light is emitted from the bundle of optical fibers banded together inside the enclosure. Mechanical or Industrial Industrial endoscopes also called a borescope or fiberscope, enables the user to observe areas that are difficult to reach or see under normal circumstances, such as jet engine interiors, inspecting mechanical welds in pipes and engines, inspecting space shuttles and rockets. Inspection of sewer lines and pipes. Networking Fiber optic is used to connect servers and users in a variety of network settings. It increases the speed, quality and accuracy of data transmission. Computer and Internet technology has improved due to the enhanced transmission of digital signals through optical fibers. Industrial/Commercial Fiber optics are used for imaging in areas which are difficult to reach. It is also used in wiring where electromagnetic interference is an problem. It gets used often as sensory devices to make temperature, pressure and other measurements as well as in the wiring of motorcars and in industrial settings. Spectroscopy Optical fiber bundles are used to transmit light from a spectrometer to a substance which cannot be placed inside the spectrometer itself, in order to analyse its composition. A spectrometer analyses substances by bouncing light off of and through them. By using optical fibers, a spectrometer can be used to study objects that are too large to fit inside, or gasses, or reactions which occur in pressure vessels Broadcast/CATV/Cable Television Broadcast or cable companies use fiber optic cables for wiring CATV, HDTV, internet, video and other applications. Usage of fiber-optic cables in the cable-television industry began in 1976 and quickly spread because of the superiority of fiber optic cable over traditional coaxial cable. Fiber optic systems became less expensive and capable of transmitting clearer signals further away from the source signal. It also reduced signal losses and decreased the number of amplifiers required for each customer. Fiber optic cable allows cable providers to offer better service, because only one optical line is needed for every  ± 500 households. Lighting and Imaging Fiber optic cables are used for lighting and imaging and as sensors to measure and monitor a vast range of variables. It is also used in research, development and testing in the medical, technological and industrial fields. Fiber optics are used as light guides in medical and other applications where bright light needs to shine on a target without a clear line-of-sight path. In some buildings, optical fibers are used to route sunlight from the roof to other parts of the building. Optical fiber illumination is also used for decorative applications, including signs, art and artificial Christmas trees. Optical fiber is an essential part of the light-transmitting concrete building product, LiTraCon which is a translucent concrete building material. Conclusion With the introduction of highly transparent fiber-optic cable in the 1970s, very high-frequency laser signals now carry phenomenal loads of telephone conversations and data across the country and around the world. From surgical procedures to worldwide communication via the internet, fiber optic has revolutionised our world. Fiber optics has made important contributions to the medical field, especially with regards to surgery. One of the most useful characteristics of optical fibers is their ability to enter the minute passageways and hard-to-reach areas of the human body. But perhaps the greatest contribution of the 20th century is the combination of fiber optics and electronics to transformed telecommunications.
