Site Management and Engineering - Essay Example For further safety of the site, an additional gate is placed just in front of the construction area, this is for occasional use. For instance movement of formwork when it is no longer required, this will not disrupt the movement at the entrance and in movement corridors, further making the site safe. The plant area is kept just in front of the construction area, as it will avoid to and fro movement of materials to construction site and save money, manpower and time. The junk area and storage area is kept at the corner end, this place will have minimum disturbance to corridor movement, will be safe from any theft and access to general public could be monitored as it is far from the working area. Lastly the rest area and cafeteria is kept opposite and away from the construction area, this will have a psychological effect on the workers as they will feel easy and this area will have least construction activities, hence least safety supervision will be required in this crowded area. Q 2 a) The most appropriate formwork system for in-situ concreting of lift walls would be Jump formwork system. This system consists of two components one being the formwork itself and the other the working platform from which the steel is fixed, concrete is poured. This type of formwork is self supporting and is most suitable for vertical elements such as lift walls. As the formwork is designed for staged processing hence it enables the speedy and efficient construction. The material of choice for our construction site would be Steel, this enables a perfect surface finish. But these steel frames must be properly designed before concrete is poured. The individual panels are attached to the frames which have different supporting conditions such roller support, once the concrete is poured and set, the panel is rolled back and a perfect finish is acquired. In the next process the jacks and lifting mechanism lifts the whole frame up one stage. The process is repeated again where panels are attached and then concrete is done. This shift of formwork and its components can take as less as 2 hours. This gives speedy and time effective solutions. Some of the views of the system made by Transkon FormworkSystem, are given in the figures below. Transkon are specialist of the field and renowned for new innovative formwork solutions. Q2 b) Although, the jump formwork provides several benefits such as the increase in construction speed and low resource requirement in terms of manpower. But at the same time it possesses considerable hazards against safety of workers and failure of formwork structural system. As mentioned earlier the formwork is self-supporting and self-climbing, hence there is the chance of structural failures of formwork, in case any joint or member fails and damages will be collateral. The first step towards safety is properly checked safe design of formwork and falsework. As these formworks work at a height hence an efficient free-fall breaking devices must be incorporated in the design. Then the platform in use must always be clear from any unnecessary material and waste should be removed as soon as possible. In addition a well maintained false work must be used for erection of the formwork and the platform. Each component must be oiled and painted properly. If excessive damages are seen in these parts they must be replaced. As our material of choice for false work and formwork is steel and metals hence corrosion of these components is to be monitored by the safety supervision team. Braces must be fastened properly, edge protections should be erected on the corners.     Ã‚  

Marketing Approaches for Overcoming Increased Competition in the UK Assignment

Marketing Approaches for Overcoming Increased Competition in the UK Hotel Industry - Assignment Example However, in practice, problems are likely to appear when having to apply the market principles related to competition. The challenges set can be many, mostly related to the lack of effective marketing policies for ensuring the equal promotion of firms within each one of the market’s industries. At this point, the identification of the characteristics of the marketing environment is considered as critical in order to understand the needs of industries and organizations and to develop valid assumptions regarding the measures required for protecting competition. In accordance with Dibb and Simkin (2001) the marketing environment can be characterized as ‘those external trading forces that directly or indirectly influence and organization’s acquisitions of inputs and generation of outputs’ (Dibb and Simkin 2001, p.199). The marketing approaches appropriate for managing the increasing competition in a specific sector, the hotel industry, of the UK market, are rev iewed in this paper. Reference is made to the characteristics of the marketing environment, as described above, but also to the differentiation of competition, compared to the past, as mostly resulted by the high development of technology worldwide. The current status of the hotel industry in UK is also described aiming to show the ways in which marketing could help the industry’s firms to face competition, which seems to be continuously increased. It is made clear that marketing can highly support firms in the hotel industry against competition. However, it is necessary for the relevant plans to be designed and promoted using particular criteria, which are analytically presented below. 2. Hotel industry in UK 2.1 Characteristics and trends Hotel industry is one of the most important sectors of UK market. In accordance with Seaton and Bennett (1996) the strength of the industry can be related to its flexibility, meaning the availability of a wide range of rooms covering the n eeds of all visitors. It is also noted that ‘short – stay bookings’ (Seaton and Bennett 1996, p.315) which result to an important part of the industry’s profits, are carefully planned in hotels across UK ensuring that short-term visitors, which are most visitors in UK, are fully satisfied with the accommodation services provided across UK. In terms of marketing, reference should be made to the different approaches used by managers of hotels in UK in order to promote their enterprise. In this context, hotel groups are likely to emphasize on ‘brand through brochures’ (Seaton and Bennett 1996, p.315); on the other hand, ‘independent hoteliers tend to use price and market destination techniques’ (Seaton and Bennett 1996, p.315). The performance of the industry can be characterized as rather disappointing. In accordance with a recent report, in 2009, firms in the particular industry had ‘to freeze recruitment at a percentage of 2 5%’ (Prospects 2009); another 24% of firms in this industry have ‘cancelled their plans to employee new staff’ (Prospects 2009). The performance of the UK hotels from 2003 up to 2009 is presented in Graph 1, Appendix. Despite the market pressures, ‘106 new hotels (with a capacity of 11,800 rooms) opened in 2011’

Comparison Of The Modern And Early Church Religion Essay

Comparison Of The Modern And Early Church Religion Essay Explaining the strengths and weaknesses of the early church, and how they compare to the church today; it is a very interesting topic since it involves the history of what early Christians did for the establishment of the Christian movement today. Looking into the Acts of the Apostles, so much can be learned on how people dedicated their lives to the church during that time. A question arises then asking, what is the church? Many interpretations have been said concerning the meaning of the Church. These interpretations can be traced back when Jesus declared to build his Church upon the revelation by Simon Peter that, when he said Jesus is the Son of God (Matt 16:18). Montefiore believes; the church can be considered fewer than two aspects; as an organism and as an organisation, without organization, organisms die1. Therefore, what is this organism and how is it linked with the organisation to make a church. To arrive at the better conclusion of this matter, I will be considering the book of Acts to get the a) background of the early church in Acts; and the b) explanation of what is the Church; c); strength and weaknesses of both the Early and Modern Church. THE CHURCH DEFINED The definition by Websters editors says: A distinct body of Christians having a common faith and discipline. In Greek language the word is translated as ekklesia, which means called out. Therefore, there are couple of things to look for, for the church to be established. Faith, discipline, and standing out from the rest. These explanation of what the Church is, gives an idea that, there are certain elements involved for a church to be established. Arguably, it means it should be made of people who follow Christ, having one faith and being disciplined, already set themselves different from the rest of ordinary people. THE EARLY CHURCH All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them (Acts 2:4). It was during the day of Pentecost which is believed the New Testament church was established. The Bible further explains that, those who were gathered during the day of celebration of Pentecost could not believe what they heard coming from the Christians who were filled with the Holy Spirit and speaking in unknown tongues. But those who were gathered understood them, because they spoke in the languages. Unger comment that: the new age of the Church was foretold by our Lord Himself and was ushered in at Pentecost, when the Holy Spirit was given, received and deposited in the new people of God. Chapter two of Acts verses (42-47), they explains what happened after Apostle Peter preached the good news about Jesus and the number of people who gave their lives to Christ, and repented from their evil ways. So this is the organism and the organisation, Montefiore was referring to, the Holy Spirit, which is divine and the people filled with this Holy Spirit to be organisation. The acts of the risen Christ by the Holy Spirit through the Apostles are prominent in the book of Acts. Evidence from this book shows strong biblical convictions held by the believers of the community in Jerusalem, also in the surrounding areas. This is how the early church began marshalled by the Apostles and I will look into details, measures taken by this dedicated individuals in Acts working together to establish a church and compare them with the church of today. WHAT STRENGHTNED THE EARLY CHURCH BAPTISM Those who accepted his message where baptised, and about three thousand were added to their number (Acts 2:41). Jesus himself edged his Apostles to go to all nations and baptise those who believe the good news about his kingdom in water. This was taken serious by the Apostles, as it was a badge for new believers for belonging to Christ; they did it in faith, even thou further teaching came after baptism, it was their believe that any Christian solider has the right be given full proper uniform. The Apostles did all this because people repented, showed faith, they received the Holy Spirit and it proved to unite them strongly and bring them closer to each other which was what they wanted. It is a different issue with the church today as most believe in monitoring the ways of those who has given their life to Christ. The time spend trying to mould a new believer into a mature Christian is the same time lost to give the new believer the responsibility to recognise the important regiment he joined in Christ. Baptism it a seal to those who accepted Christ and it was done by the church in Acts to stabiliser new converts, but today it is not practised at the right time. Therefore, the new believers are not united with other and they end up being lost back to the world. HOLY SPIRIT According to the accounts of Acts, there is prove that, the people obeyed the Holy Spirit more than anything, and it gave them the unity as a community. Holy Spirit spoke (Acts 8:29, 10:19) and immediate response from those who were assigned by the Spirit to do something went on and accomplished the tasks as believers. Jews and Gentiles those who trusted in Christ were all given the Holy Spirit. This was so significant since at fist Jews disapproved the Gentiles as Gods people; but now because the Spirit dwelt in those who believed both are united and they were all called from indifference into unity to serve God by the Holy Spirit. The church of today when looking back on how the church in Acts responded to the Holy Spirit it has some eye brows raised. This is so because there are so many denominations under Christianity and they all have their own beliefs. So they all have different interpretation of the Holy Spirit impact in the church and some even do not pay attention to it at all. He promised to send a comforter to live amongst Christians and he will guide them in their everyday living. This is what held the church in Acts stronger since they believed Holy Spirit and God are one. But that is being missed within different Christian faiths today. Church members are controlled by their own understanding and intelligence, and those who claim to be controlled by the Spirit they always find themselves in dilemma of practical life and Spiritual life. FELLOWSHIP Examining the Acts of the Apostles, it is evident that a very strong fellowship was established between Christian believers in Jerusalem because of the love they had for each other (Acts 2:42). In John 1: 6-7, explains the fellowship principle of Christian living and it the same fellowship the church in Jerusalem practised. They shared possessions, sold properties to care for one anothers needs. The fellowship of the early church consisted different forms to make sure that everyone was involved in unifying the church. Personal attention which involved encouragement and advice from other church members, one on one with those they brought to church. Furthermore, they met in homes so that others adjust to the new society. This led to a bigger and a welcoming church congregation fellowship, which everyone was used to one another and that strengthened the church. Comparing what the early church practised in fellowship with the church today, not much difference but there is lack of commitment. Hardly members within the church fellowship in homes and if they do the number is always very small. No enthusiasm in encouraging and helping new converts to settle in with the new society. WEAKNESS OF THE EARLY CHURCH Major unsettling concern with the church in Acts is the issue of favouritism. It is exposed by none Palestinian Jews who spoke against unfairness of daily share which was given out to church members. This caused arguments and division within church members who were united by faith in Jesus. Even today favouritism is noticeable in the churches across, either because people come from same country, continent or same denomination, and all this bring weakness in the body of Christ. Another short fall from the primitive church is the extension of love that Jesus summoned his followers to show to their neighbours. It seems different with the church in Acts as the mutual love was first shown to those within the fellowship of the church. This in other way chased those who were willing to come to the church for the first time as it made them feel unwelcomed. CONCLUSION Explaining the strengths and weakness of the early church, compared to the church today is a very informative topic as it allows Christians to reflect on their purpose in the world. After consulting different sources concerning the topic, I have come to realisation that the early church was more profound in making sure that the good news about Jesus was spread without compromise. The teaching of the word about who Jesus is was so rich that, more and more people joined the church everyday. The fellowship of church members brought light to the community as it influenced their way of living. The church in the New Testament played their role to call out those who were in darkness to bring them to light which Jesus promised them if they love one another. Comparing both the early and the church today, very important thing that should be learned is that the early church was so excited to be followers of Jesus and they were spiritually motivated. Christians today need that excitement to occupy their daily life to glorify Jesus because he is the source of life and the world needs him at this age.

Building Trust and Security in Web Services :: Technology Computers Internet Essays

Building Trust and Security in Web Services The yearning to componentize software development, where software is "assembled" like an automobile, where each component interacts with the other components in an unambiguous and streamlined fashion is very old and deep rooted. For, the most significant challenges in software development are maintaining and changing software pieces which perform redundant functions and integrating such components with one another. As the industry started to mature, significant research has taken place to find ways of architecting software components as building blocks that are seamlessly integrated, irrespective of where those components reside or how they are implemented. CORBA and COM arrived on the scene addressing these issues and providing a sound architecture for distributed computing. While these very interesting developments were going on, the Internet revolution took place simultaneously as more and more businesses started to register their presence on the web. E-business and e-commerce have seen tremendous growth in the past 7 years where major business functions are taking place through the medium of internet and some businesses are run entirely on the Internet. As a result more and more business software processes had to interact with their business counterparts over the Internet. The eventual convergence of these two paradigm shifts in the software development resulted in the birth of Web Servic es. Web Services are fundamental building blocks of software that are deployed in heterogeneous software and hardware platforms, that describe and publish their behavior to potential consumers (UDDI), based on a software contract (WSDL) interact with consumers by receiving and sending (XML) messages through a common protocol (SOAP). The scenario where a software component can dynamically detect, contract and utilize services provides a strong semantic connection to the web and may truly revolutionize the web. But the prospect of unprecedented inter-connectivity comes with huge challenges of security and raises serious questions on ethics and legalities. Some of the challenges are Security: How to prevent unauthorized access to critical information, code or a business process? Moreover the pertinent question is how to prevent misuse of critical information, code or a business process, gained by authorized access. Trust and Verification: What should be the parameters that enables establishing trust between a potential consumer and a provider? Even if 'trust' is established how can the consumer 'verify' the trust? Ownership and Responsibility: How to enforce ownership rights and accountability? When there is a software failure who owns up for it ?

When the Leeves Broke

Cruz 1 Carolina Cruz Professor Gwaltney English 1102 March 14, 2013 When the Levees Broke: A Rhetorical Analysis It is nearly impossible to imagine that one day you can be safe in your home and with all of your belongings and the next day a hurricane leaves you with nothing. Unfortunately, the 484,000 people who lived in New Orleans had to experience those unimaginable thoughts first hand in 2005 due to Hurricane Katrina. â€Å"An entire city was nearly wiped off the face of the earth† (Kellogg) and at least 1,833 people were killed during and after the storm.There are many theories and conspiracies of what happened with the levees and what could have been done better in order to help the residents of New Orleans. Director Spike Lee felt very strongly about the issue and decided to make a documentary in order to give the people of New Orleans justice. By directing When the Levees Broke, Spike Lee gives the audience his personal view on the entire situation dealing with Hurrica ne Katrina and her aftermath. With his use of video editing and choice of certain interviews, Lee gave not only emotional credibility to his movie but also a logical point of view.The main argument of the documentary was to explain the series of events that occurred during and following the storm, while also getting the inside point of views of some of the Hurricane Katrina victims. Another argument Spike Lee was trying to make Cruz 2 was that there was a lot more to the disaster than just the storm. I do believe that Lee did a good job in getting his point across in his documentary but I do not believe it was a very strong argument. The argument is not very convincing because not everyone’s view was included in the film.It seems that Spike Lee was very biased while making the documentary and had no problem with expressing it in his film. Though I do somewhat agree with Lee’s point of view, I do not believe that it was a very well rounded argument. In his documentary, Lee confronts the underlying problems that occurred at the time of the hurricane such as racial, cultural and political issues. By adding so much information about what was actually occurring during Hurricane Katrina in his film, Lee made a very well put together documentary.Lee’s purpose of making the film was to give the victims their chance to speak out and to show â€Å"how the poor and underprivileged of New Orleans were mistreated in this grand calamity and still ignored today† (Chisholm). Lee is a very passionate and outspoken man and he conveyed his message in a way where the victims had the upper hand and could speak on the real issues. Had Spike Lee not been so biased, I think both his argument and documentary could have been excellent. Spike Lee used the Aristotelian appeal of pathos the most throughout his documentary in order to catch the audience’s attention.The way he incorporates certain cultural music and photos of the aftermath of Hurricane Kat rina make the audience more inclined to pay attention. The collection of photographs Lee features in his film not only let us see what was happening during Hurricane Katrina, they also â€Å"add texture and even further weight to these stories† (Kellogg). He does this on purpose in order to make the audience feel sympathy towards all the people who were interviewed as well as those Cruz 3 who passed away due to Hurricane Katrina.The best way Lee kept the attention of the audience was by â€Å"allowing the people who lived through the disaster to tell their stories† (Kellogg). The viewer is more likely to pay attention if they are stimulated emotionally and that is what Spike Lee aimed for. He also shows the audience how the â€Å"evacuation process separated parents from children as people were loaded onto buses,† by doing this, the audience gets a more in depth view of the disaster and is more likely to feel sad and watch the documentary more.The underlying iss ue that Lee was trying to explain to the audience was that â€Å"the storm was damaging by itself, but that was not the true disaster† (Chisholm). Some critics do not believe that Spike Lee was meant to make this film because he did not capture everyone’s point of view. This film is supposed to be about just the victims opinion on what they thought about the situation dealing with the government and Hurricane Katrina. I think he was well fit for the job because Lee’s â€Å"films have looked unflinchingly at some of the most polarizing subjects† (Jacobs) nd it was no shock that he made this documentary about Hurricane Katrina. There were many criticisms about the documentary such as; it did not necessarily discuss all of the people of New Orleans and it gave us a bad view of the government. Lee had his own conspiracy on how the levees were blown up as opposed to just being ruined by the hurricane. Lee’s film was also criticized because it â€Å"sug gested that the explosion assured that the poor neighborhoods be damaged and not the rich developments further down† (Jacobs) and that did not take well with the conservative circles.Another reason his documentary was Cruz 4 faulty was because it had a very biased standpoint and â€Å"Mr. Lee’s documentary boils with anger and a degree of paranoia† (Holden). The three main topics this documentary touched on were those such as politics, cultural issues and racial issues. There were many complaints within the movie about the government from the victims of Hurricane Katrina. The people of New Orleans were outraged by the â€Å"tardy response of the Bush administration to the crisis† (Jacobs).A large portion of the documentary focused on the lack of help from the government, it explained how a few government officials took longer than normal to help with the disaster in New Orleans. The fact that bodies were still being found after F. E. M. A supposedly search ed all the houses was a big concern for the people. F. E. M. A had not been giving the victims the proper care they needed for the amount of time that they had left and that was a very high concern to the people who desperately needed help from F.E. M. A. George Bush and Dick Chaney were also spoken upon in a bad manner as well because they had more important things to do rather than help the dying people of their own country. Just like most of his other films, Spike Lee made his documentary mostly about race. At one point in the movie it explains how the disaster started the â€Å"racist, vigilante atmosphere which gave cops and soldiers carte blanche to shoot on sight ‘looters’† (Onesto) and how they were not afraid to follow through with orders.The majority of the people Lee interviewed were poor and black and were treated very poorly. In this film, Lee insinuates that the victims are being treated like slaves and separated from their families. He expresses â €Å"the truth of how the institutions of white supremacy and the ideas of racism are woven into the very workings of this system of U. S. capitalism† (Onesto). Culture is a big deal in Cruz 5 New Orleans; the people consider their culture the most important and valuable thing to them.A very large part of the New Orleans culture is Mardi Gras and it was a concern of the people whether they should or should not have the celebration the following year after Hurricane Katrina. Mardi Gras is an annual celebration and even the hurricane could not completely bring the residents of New Orleans down. Spike Lee wanted to show that even though the city looked bad, the people of New Orleans still had their high spirits. All the controversy involving New Orleans such as race, politics and culture lured Spike Lee to make a documentary about the hurricane.Based off his previous films Lee was fit to make this film and did a good job in conveying his message. With this use of enhanced photogr aphy and video editing Lee was able to make an informative yet captivating film that showed the other side of the story. In his documentary, we can finally â€Å"put human faces on the devastation† (Jacobs) and realize that these people were once like us in their homes. His film not only allows us to see what occurred in August of 2006, but it lets us hear the individual stories and realize what we were not told by the government.The documentary gives us the victims view of the disaster and it makes the viewer more aware of the devastation that the people of New Orleans had to face. By making this documentary, Lee not only helped explain the troubles of the victims of Hurricane Katrina but he also let the people come out and express how they felt during the evacuation and rebuilding process.

Changes And Urban Expansion In Greater Dhaka Environmental Sciences Essay

This survey evaluates old termland usage alterations and urban enlargement in Greater Dhaka, Bangladesh, between 1975 and 2003 utilizing satellite images and socio-economic informations. Spatial and temporal kineticss of old termlandnext term use/cover old termchangesnext term were quantified utilizing three Landsat images, a supervised categorization algorithm and the post-classification old termchangenext term sensing technique in GIS. Accuracy of the Landsat-derived old termlandnext term use/cover maps ranged from 85 to 90 % . The analysis revealed that significant growing of built-up countries in Greater Dhaka over the survey period resulted important lessening in the country of H2O organic structures, cultivated old termland, following term flora and wetlands. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Rapid old termurban expansionnext term through infilling of low-lying countries and glade of flora resulted in a broad scope of environmental impacts, including habitat quality. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms. Urbanization is one the most widespread anthropogenetic causes of the loss of cultivable old termlandnext term ( Lopez, Bocco, Mendoza, & A ; Duhau, 2001 ) , habitat devastation ( Alphan, 2003 ) , and the diminution in natural flora screen. The transition of rural countries into old termurbannext term countries through development is presently happening at an unprecedented rate in recent human history and is holding a pronounced consequence on the natural operation of ecosystems ( Turner, 1994 ) . Although old termurbannext term countries presently cover merely 3 % of the Earth ‘s old termlandnext term surface, they have marked effects on environmental conditions at both local and planetary graduated tables ( [ Herold etA al. , 2003 ] and [ Liu and Lathrop, 2002 ] ) , including clime old termchangenext term ( Grimm, Grove, Pickett, & A ; Redman, 2000 ) . Since ecosystems in old termurbannext term countries are strongly influenced by anthropogenetic activities, well more attendi ng is presently being directed towards supervising old termchangesnext term in old termurban landnext term usage and old termlandnext term screen ( LULC ) ( Stow & A ; Chen, 2002 ) . Such surveies are peculiarly of import because the spacial features of LULC are utile for understanding the assorted impacts of human activity on the overall ecological status of the old termurbannext term environment ( Yeh & A ; Li, 1999 ) . LULC old termchangenext term due to human activities is presently continuing more rapidly in developing states than in the developed universe, and it has been projected that by the twelvemonth 2020, most of the universe ‘s mega metropoliss will be in developing states ( World Bank, 2007 ) . Increasing population in developing metropoliss has caused rapid old termchangesnext term in LULC and increased environmental debasement ( Holdgate, 1993 ) . The consequence of population is peculiarly relevant given that the planetary old termurbannext term population is projected to about duplicate by 2050 ( UN, 2008 ) . In order to extenuate the damaging effects associated with old termurbannext term growing on the environment and to keep optimum ecosystem operation ( Fang, Gertner, Sun, & A ; Anderson, 2005 ) , spacial and temporal LULC forms, and the factors impacting these old termchangesnext term ( Serra, Pons, & A ; Sauri , 2008 ) , are well of import in developing rational economic, societal and environmental policies ( Long, Tang, Li, & A ; Heilig, 2007 ) . Bangladesh has experienced rapid old termurbannext term population growing in recent decennaries ; the population numbered 14.1 million in 1981, 22.5 million in 1991, 31.1 million in 2001 ( BBS, 2001 ) and 35 million in 2005 ( CUS, NIPORT, & A ; MEASURE, 2006 ) . Rapid urbanisation has led to the transmutation of rural countries into developed countries, and it has been estimated that more than 809A km2 of agricultural old termlandnext term is converted to metropoliss, roads and substructure yearly ( BBS, 1996 ) . The lessening in agricultural activities, the largest sector of the Bangladeshi economic system, and the attendant loss of cultivated old termlandnext term is likely to lend to landlessness, nutrient deficits and endanger the economic system ( Ahmad, 2005 ) . Dhaka, the capital of Bangladesh, is expected to be the 3rd largest metropolis in the universe by 2020 ( World Bank, 2007 ) and the rapid old termurbannext term growing experienced by the metropolis in recent decennaries is one of the highest in the universe ( [ Islam, 1999 ] and [ Islam, 2005 ] ) . old termUrban expansionnext term of Dhaka was slow in the 1950s, but strong growing followed the independency of Bangladesh in 1971 ( Chowdhury & A ; Faruqui, 1989 ) . The considerable growing observed in the population of Dhaka is thought to hold occurred in response to large-scale rural-previous termurbannext term migration, which has contributed, significantly to the increased rate of urbanisation ( Islam, 1996 ) . To day of the month, the environmental and socio-economic sustainability of Dhaka, which is indispensable for development planning, has received comparatively small attending. This has resulted in widespread environmental jobs across the metropolis, mostly stemming from unpl anned urbanisation, extensive old termurbannext term poorness, perennial episodes of implosion therapy, significant growing of slums, development of resources, and the misdirection of limited old termlandnext term resources ( Hasan & A ; Mulamoottil, 1994 ) . Geographic Information Systems ( GIS ) and distant detection ( RS ) are powerful and cost-efficient tools for measuring the spacial and temporal kineticss of LULC ( [ Hathout, 2002 ] , [ Herold etA al. , 2003 ] , [ Lambin etA al. , 2003 ] and [ Serra etA al. , 2008 ] ) . Distant feeling informations provide valuable multi-temporal informations on the procedures and forms of LULC old termchange, following term and GIS is utile for function and analysing these forms ( Zhang etA al. , 2002 ) . In add-on, retrospective and consistent synoptic coverage from orbiters is peculiarly utile in countries where old termchangesnext term have been rapid ( Blodget, Taylor, & A ; Roark, 1991 ) . Furthermore, since digital archives of remotely sensed informations provide the chance to analyze historical LULC old termchanges, following term the geographic form of such old termchangesnext term in relation to other environmental and human factors can be evaluated. Numerous old termchangenext term sensing methods have been developed to measure fluctuations in LULC utilizing satellite informations ( [ Coppin etA al. , 2004 ] , [ Lu etA al. , 2004 ] and [ Singh, 1989 ] ) . Of these techniques, the pre- and post-classification comparings have been extensively used ( [ Coppin etA al. , 2004 ] and [ Singh, 1989 ] ) . In the pre-classification attack, processs such as image differencing ( Toll, Royal, & A ; Davis, 1980 ) , band rationing ( Nelson, 1983 ) , old termchangenext term vector analysis ( Johnson & A ; Kasischke, 1998 ) , direct multi-date categorization ( Li & A ; Yeh, 1998 ) , flora index differencing ( Townshend & A ; Justice, 1995 ) and principle constituent analysis ( Fung & A ; LeDrew, 1987 ; Hartter, Lucas, Gaughan, & A ; Aranda, 2008 ) have been developed ( [ Hardin etA al. , 2007 ] , [ Jensen, 1996 ] and [ Singh, 1989 ] ) . The basic premiss of these processs is that old termchangesnext term in LULC consequence in differences in the pel coefficient of reflection values between the day of the months of involvement. However, while these techniques are effectual for turn uping old termchange, following term they can non place the nature of old termchangenext term ( Ridd & A ; Liu, 1998 ) . Conversely, post-classification comparings examine old termchangesnext term over clip between independently classified old termlandnext term screen informations. Despite the troubles associated with post-classification comparings ( [ Coppin etA al. , 2004 ] and [ Singh, 1989 ] ) , this technique is the most widely used for placing LULC old termchangesnext term ( [ Jensen, 1996 ] and [ Lu etA al. , 2004 ] ) , peculiarly in old termurbannext term environments ( Hardin etA al. , 2007 ) . However, one of the disadvantages associated with this attack is that the truth of the end point LULC old termchangenext term maps depends on the truth of the single categorization, intending that such techniques are capable to error extension ( Y uan, Sawaya, Loeffelholz, & A ; Bauer, 2005 ) . However, such post-classification techniques are peculiarly utile for bring forthing ‘from-to ‘ maps ( Jensen, 1996 ) , which can be used to clear up the magnitude, location and nature of the old termchangesnext term shown ( Howarth & A ; Wickware, 1981 ) . In add-on, the technique can be employed utilizing informations acquired from detectors with different spatial, temporal and spectral declarations ( [ Alphan, 2003 ] and [ Coppin etA al. , 2004 ] ) . RS is really effectual for exemplifying the interactions between people and the old termurbannext term environments in which they live ( Gatrell & A ; Jensen, 2008 ) . Space-borne orbiter informations are peculiarly utile for developing states due to the cost and clip associated with traditional study methods ( Dong, Forster, & A ; Ticehurst, 1997 ) , and these techniques have become feasible options to conventional study and ground-based old termurbannext term mapping methods ( Jensen, Hodgson, Tullis, & A ; Raber, 2004 ) . Several surveies have demonstrated the pertinence of RS to developing sourcing information and for back uping decision-making activities in a broad scope of old termurbannext term applications ( [ Gatrell and Jensen, 2008 ] , [ Jensen and Cowen, 1999 ] and [ Zeilhofer and Topanotti, 2008 ] ) . In the country of old termurbannext term planning, of import RS research has been conducted to day of the month, peculiarly in old termurban changenext term analysis and th e mold of growing ( [ Bahr, 2004 ] , [ Hardin etA al. , 2007 ] , [ Hathout, 2002 ] , [ Herold etA al. , 2003 ] , [ Jat etA al. , 2008 ] , [ Jensen and Im, 2007 ] , [ Liu and Lathrop, 2002 ] , [ Maktav and Erbek, 2005 ] , [ Ridd and Liu, 1998 ] , [ Yang, 2002 ] and [ Yuan, 2008 ] ) , LULC rating ( [ Alphan, 2003 ] , [ Lopez etA al. , 2001 ] , [ Xiao etA al. , 2006 ] , [ Yang and Lo, 2002 ] and [ Yuan etA al. , 2005 ] ) , and old termurbannext term heat-island research ( [ Kato and Yamaguchi, 2005 ] and [ Weng, 2001 ] ) . In peculiar, RS-based multi-temporal old termlandnext term use old termchangenext term informations provide information that can be used for measuring the structural fluctuation of LULC forms ( Liu, Gao, & A ; Yang, 2003 ) , which can be applied to avoiding irreversible and cumulative effects of old termurbannext term growing ( Yuan, 2008 ) and are of import to optimise the allotment of old termurbannext term services ( Barnsley & A ; Barr, 1996 ) . In add-on, accura te and comprehensive old termlandnext term use old termchangenext term statistics are utile for inventing sustainable old termurbannext term and environmental planning schemes ( [ Alphan, 2003 ] and [ Jensen and Im, 2007 ] ) . It is hence really of import to gauge the rate, form and type of LULC old termchangesnext term in order to foretell future old termchangesnext term in old termurbannext term development. Small is known about the spacial and temporal dimensions of the LULC old termchangesnext term that have shaped the old termurban expansionnext term of Greater Dhaka. Although most developed states have both recent and extended LULC information, the comparative deficiency of geospatial informations or entree thereto, is prevailing in developing states, peculiarly in Bangladesh. For case, aerial exposure are classified for the populace. The metropolis does non hold any official statistics on old termlandnext term usage forms, and the Master Plans do non incorporate either a map or quantitative information on the bing forms of old termlandnext term usage in the metropolis ( [ Islam, 1996 ] and [ Islam, 2005 ] ) . The old termlandnext term usage forms of Greater Dhaka were officially categorized in 1991 utilizing land observation informations ( Flood Action Plan ( FAP ) 8A, 1991 and [ Islam, 2005 ] ) . Due to the easiness of entree and recent nature of nose count records, the local autho ritiess of Dhaka often use nose count informations to construe old termlandnext term use old termchanges.next term As a consequence, the kineticss of development are non clear and frequently deceptive ( Talukder, 2008 ) . Numerous factors, including fiscal restraints, restricted entree to informations, bureaucratism and deficiency of geospatial expertness in the planning bureaus account for the absence of historical and current old termlandnext term usage informations. Furthermore, every bit many as 18 ministries are involved in the development and planning of Dhaka, and there is a general deficiency of coordination between these organic structures ( Mohit, 1991 ) . This empirical survey will try to place the spatio-temporal form of LULC old termchangesnext term for Greater Dhaka utilizing geospatial informations so that both the scientific community and determination shapers can measure the assorted kineticss impacting LULC old termchangesnext term in this old termurbannext term en vironment. The aims of this survey were therefore to research the features of LULC old termchangesnext term and qualify the underlying drive forces in the Greater Dhaka country by doing usage of remotely sensed informations and socio-economic information. Specifically, the aims are: ( a ) to clarify and measure the LULC old termchangesnext term between 1975 and 2003 ; ( B ) to research the spacial and temporal features of old termurban expansionnext term in this period ; and ( degree Celsius ) to analyse the drive forces of old termlandnext term use old termchange and urban expansion.next termStudy countryAs shown in Fig.A 1, the survey country of Greater Dhaka is located in the centre of Bangladesh between 23A °68aˆ?N ( BTM 533233.91A m ) , 90A °33aˆ? E ( BTM 619052.83A m ) and 23A °90aˆ?N ( BTM 550,952.57A m ) , 90A °50aˆ? E ( BTM 642511.56A m ) , severally. Topographically, the country is level with a surface lift runing from 1 to 14A m ( Fig.A 1 ) , with most old ter murbannext term countries located at lifts runing from 6 to 8A m ( FAP 8A, 1991 ) . The metropolis is situated chiefly on an alluvial patio, popularly known as the Modhupur patio dating from the Pleistocene period. The survey country is surrounded by four major river systems: the Buriganga, Turag, Tongi and the Balu, which flow to the South, west, north and east, severally. These rivers are chiefly fed by local rainfall and besides receive overflow from the well larger Ganges, Brahmaputra and Meghna rivers. The metropolis has a humid sub-tropical monsoon clime and receives about 2000A millimeters of rainfall yearly, more than 80 % of which falls during the monsoon season from June to September. Life-size image ( 137K ) – Opens new window Life-size image ( 137K ) Fig.A 1.A Location of survey country. River webs, embankment and administrative units are draped over a digital lift theoretical account. Brightest countries represent higher lift ; bright grey represents average lift while dark pels show the lowest lift.Position Within ArticleThe happening of heavy monsoon rainfall combined with floodwater overflow from the rivers environing the metropolis mean that Dhaka is really prone to monsoon implosion therapy. The metropolis has experienced a figure of lay waste toing inundations in recent times, with the inundations in 1988, 1998 and 2004 being the most terrible ( Alam & A ; Rabbani, 2007 ) . Quantitative appraisals of the countries inundated by these flood events revealed that in 1988, 47.1 % of greater Dhaka were flooded, while in 1998 and 2004, about 53 % and 43 % countries were inundated ( [ Dewan etA al. , 2007 ] , [ Dewan and Yamaguchi, 2008 ] and [ Dewan etA al. , 2006 ] ) . The inundations caused harm to lodging and substructure amou nting to US $ 2.2A m in 1988, 4.4A m in 1998 and 5.6A m in 2004 ( Ahmed, Gotoh, & A ; Hossain, 2006 ) . The badness of inundation harm was considerable, even in 2004, which was considered more moderate of the three inundations, and which was believed to be the consequence of hapless old termurbannext term planning and renewal and development of natural countries, such as wetlands and low-lying countries, that would otherwise hold attenuated the implosion therapy. A survey utilizing hydrological record and RS-based LULC information has shown that inundation continuance and extent has increased well as a consequence of the extended old termurbannext term development on Lowlandss and flood plains of natural river channels ( Dewan & A ; Yamaguchi, 2008 ) . It has been suggested that the exposure of Dhaka to deluge harm will increase due to continued unplanned old termurban expansionnext term ( Faisal, Kabir, & A ; Nishat, 1999 ) and the consequence of clime old termchangenext term ( Ala m & A ; Rabbani, 2007 ) , and that these in bend will increase the agony to the dwellers of Dhaka and do extended harm to belongings in the part.Data and methodological analysisData acquisition and readyingLandsat informations ( MSS, TM and ETM+ ) were acquired and used to measure LULC old termchanges and urban expansionnext term in Dhaka. Geometric rectification was performed on all the images utilizing a Landsat TM image of the same country from 1997 as mention. At least 45 land control points ( GCPs ) were used to register the images to the Bangladesh Transverse Mercator ( BTM ) system. GCPs were dispersed throughout the scene, giving a RMS mistake of less than 0.5 pels. A first order multinomial tantrum was applied and images were resampled to 30A m end product pels utilizing the nearest neighbour method. All brooding sets were used in image categorization and the thermic set was excluded. In add-on, geospatial informations including municipal boundaries, route webs, geomorphic units and lift units were used to bring forth GIS beds from beginnings such as Survey of Bangladesh ( SOB ) topographical maps ( sheet no. 79 I 5 & A ; 6 ) , municipal boundary map and geomorphic map ( Asaduzzaman, Nasreen, & A ; Olsen, 1999 ) . Multi-year socio-economic informations were obtained from Bangladesh Bureau of Statistics ( BBS ) and published literature ( [ Islam, 1996 ] , [ Islam, 2005 ] and [ Siddiqui etA al. , 2000 ] ) . Reference informations, which varied given the retrospective nature of the survey ( Table 1 ) , were used for both developing country choice and for the rating of map truth. In add-on to utilizing high-resolution imagination, intensive fieldwork was conducted in the survey country from 6 February to 22 March 2003 to roll up land truth information for the analysis of the 2003 image. A hardcopy false colour composite ETM+ ( RGB 432 ) image picturing different LULC types was used in the field to place bing old termlandnext term screen characteristics, with particular attending given to spectrally similar characteristics. Based on this fieldwork, a land truth map was prepared for turn uping preparation pels on the image and 200 mention informations points were collected utilizing a planetary placement system ( GPS ) . This GPS information was so overlaid with the image in GIS to choose developing countries and for accuracy appraisal ; 100 of the GPS points were used for trying and the ot her 100 were used for measuring the truth of the categorization.

Specifically, extra factors such as the major old termlandnext term usage classs within the survey country and differences in the spacial declaration of the images, which varied from 30 to 79A m, were considered in planing the categorization strategy. Six separate LULC types were identified: H2O organic structures, wetlands/lowlands, built-up countries, cultivated old termland, following term flora and bare soil/landfill ( Table 2 ) . Table 2. old termLandnext term use/cover categorization strategy. old termLandnext term use/Cover TypesDescriptionBuilt-up Residential, commercial and services, industrial, transit, roads, assorted old termurban, following term and other old termurbannext term Bare soil/landfill sites Exposed dirts, landfill sites, and countries of active digging Cultivated old termlandnext term Agricultural country, harvest Fieldss, fallow old termlandsnext term and vegetable old termlandsnext term Vegetation Deciduous forest, assorted forest old termlands, following term thenars, conifer, chaparral and others Water organic structures River, lasting unfastened H2O, lakes, pools and reservoirs Wetland/lowlands Permanent and seasonal wetlands, low-lying countries, marshy old termland, following term rivulets and gully, swamps Full-size tabular arrayPosition Within ArticleAll orbiter informations were studied utilizing spectral and spacial profiles to determine the digital Numberss ( DNs ) of different LULC classs prior to categorization. Training samples were selected from the mention informations and accessory information ( Table 1 ) . Sixty to seventy preparation sites, runing in size from 286 to 7800 pels, were used to develop the images. Training samples included 5-10 subclasses for each category except for bare soil/landfill. The preparation samples were so refined, renamed, merged, and deleted after rating of the category histogram and statistical parametric quantities. A supervised upper limit likeliness categorization ( MLC ) algorithm, antecedently demonstrated to obtain the best consequences from remotely sensed informations if each category has a Gaussian distribution ( Bolstad & A ; Lillesand, 1991 ) , was so applied to each image. However, several of the categories were falsely classified in the supervised categorization of LULC, with certain old termurbannext term colonies being misclassified as landfill sites due to their holding similar spectral features. Similarly, the wetland category was merged with the lowland category as it was non possible to divide them due to similar spectral belongingss, and the wetland/lowland class and cultivated old termlandnext term were besides falsely classified. Post-classification polish was hence used to better the truth of the categorization as it is a simple and effectual method ( Harris & A ; Ventura, 1995 ) . In add-on, since the old termurbannext term surface is heterogenous and composed of a complex combination of characteristics ( e.g. edifices, roads, grass, trees, dirt, H2O ) ( Jensen, 2007 ) , assorted pels are a common job when utilizing medium-spatial declaration informations such as Landsat ( Lu & A ; Weng, 2005 ) . The job of assorted pels was addressed in several ways. For illustration, thematic information ( e.g. H2O organic structures, flora, and bare dirt ) was foremost extracted from the Landsat informations utilizing the V-S-W index ( Yamagata, Sugita, & A ; Yasuoka, 1997 ) , before a rule-based technique utilizing thematic information and GIS informations ( e.g. DEM, municipal maps and H2O organic structures, etc. ) was employed in ERDAS spacial modeller to rectify antecedently misclassified old termlandnext term scree n classs. Although this rule-based technique greatly improved the MLC categorization, some misclassification between wetland and cultivated old termlandsnext term was still observed, chiefly because of the geographical adjacency of these classs. GIS tools, such as Area of Interest ( AOI ) were so applied to the informations utilizing ocular analysis, mention informations, every bit good as local cognition, to divide and recode these screens so that they more closely reflected their true categories. By using these techniques, the consequence obtained utilizing the supervised algorithm could be well improved. Finally, to cut down the salt-and-pepper consequence, a 3A A-A 3 bulk filter was applied to the classified old termlandnext term screens ( Lillesand & A ; Kiefer, 1999 ) .Accuracy appraisalBy and large, categorization truth refers to the extent of correspondence between the remotely sensed informations and mention information ( Congalton, 1991 ) . In order to measure the truth of old termlandnext term screen maps extracted from Landsat informations, a sum of 125 graded random pels were generated for the 1975 and 1992 informations and 100 pels for the 2003 old termlandnext term screen map. Accuracy appraisal of the LULC maps was so performed utilizing field informations and the geographical characteristics on old termlandnext term usage maps, high-resolution images, and SOB topographic maps, and the consequences were recorded in a confusion matrix. A non-parametric Kappa trial was besides used to mensurate the categorization truth as it accounts for all the elements in the confusion matrix instead than merely the diagonal elements ( Rosenfield & A ; Fitzpatirck-Lins, 1986 ) . The entire truth of the Landsat-derived LULC information was 85.6, 89.6 and 90 % with matching Kappa statistics of 82.7, 87.5 and 87.9 % for MSS, TM and ETM+ , severally, confirming the standard truth of 85-90 % for LULC mapping surveies as recommended by Anderson etA Al. ( 1976 ) . The application of rule-based post-classification polish was found to be effectual and improved truth by 10-12 % . The MSS image had the lowest overall truth, which may be due to its harsh spacial declaration ( Haack, 1987 ) . Yang and Lo ( 2002 ) besides noted that the jobs associated with right sorting assorted pels additions with diminishing image declaration, ensuing in spectral confusion. In this survey, spectral confusion was higher in the MSS image than in the TM/ETM+ images. old termChangenext term sensing This survey employed the post-classification old termchangenext term sensing technique, which is efficient in observing the nature, rate and location of old termchanges, following term and has been successfully used by a figure of research workers in the old termurbannext term environment ( Hardin etA al. , 2007 ) . An overlay process utilizing the GIS was adopted in order to obtain the spacial old termchangesnext term in LULC during three intervals: 1975-1992, 1992-2003 and 1975-2003. Application of this technique resulted in a bipartisan cross-matrix, depicting the chief types of old termchangenext term in the survey country. Cross tabular matter analysis on a pixel-by-pixel footing facilitated the finding of theA measure of transitions from a peculiar old termlandnext term screen category to other old termlandnext term usage classs and their corresponding country over the period evaluated. A new thematic bed incorporating different combinations of â€Å" from-to † old termc hangenext term categories was besides produced for each of the three six-class maps. LULC old termchangesnext term and kineticss of old termurban expansionnext term Spatial forms of LULC old termchangesnext term in the Greater Dhaka country for 1975, 1992 and 2003 are shown in Fig.A 2. In 1975, lowlands, cultivated countries and H2O organic structures were the dominant old termlandnext term usage types, and the way of old termurban expansionnext term ( herein referred to as the built-up class ) was northerly. In 1992, the built-up class replaced most of the H2O organic structures and depressions within the metropolis every bit good as the cultivated old termlandnext term along the peripheral zone. Surveies of historical maps and the available literature suggest that the depressions and H2O organic structures within the metropolis disappeared comparatively rapidly after independency as countries were developed for residential, commercial, academic and concern intents ( Siddiqui etA al. , 2000 ) . Between 1975 and 1992, when route transit from Dhaka to the backwoods was improved by the building of Bridgess over the rivers ( Islam, 1996 ) , old ter murban expansionnext term extended further to the North, north-west and to the West. Consequently, the country of cultivated old termlandnext term and H2O organic structures declined markedly during the period 1975-1992 ( Louis Berger & A ; BCL, 2005 ) . In 2003, the forms of LULC old termchangenext term revealed that Dhaka started to spread out in all waies, chiefly at the disbursal of vegetated and wetland/lowland countries. The rate of old termurbannext term invasion ( Fig.A 2 ) on other old termlandnext term utilizations increased significantly following the readying of a new Master Plan in 1995 and the development of substructure ( Siddiqui etA al. , 2000 ) . The building of a span over the Buriganga River accelerated old termurban expansionnext term in the southern and northwesterly waies. The spacial distribution of the exposed soil/landfill class is besides seeable in the maps produced ( Fig.A 2 ) , clearly exemplifying the transmutation of lowland countries to landfills on the outskirts of Dhaka. Life-size image ( 292K ) – Opens new window Life-size image ( 292K ) Fig.A 2.A Classified old termlandnext term use/cover maps of Greater Dhaka in 1975, 1992 and 2003.Position Within ArticleThree sectors, viz. the populace, private, and individual-household sectors, are responsible for all of the old termlandnext term developments in Dhaka. Most of the old development undertakings were undertaken on an ad hoc footing by the populace sector, chiefly in countries that were antecedently used for agribusiness and that were free from flood ; illustrations of such developments include Gulshan Model Town, Banani, Uttara Model Town and Dhanmondi ( Chowdhury, 2003 ) . In recent old ages, belongings development has proliferated in Dhaka, and belongings developers have developed both wetlands and agricultural countries without any consideration of the attendant environmental costs. In add-on, single families have started to develop the peripheral countries ( Islam, 1996 ) . In the fieldwork conducted in this survey, old termlandnext term guess was observed to ho ld had a pronounced influence on the development of suburban countries. In response to increasing old termlandnext term monetary values and turning demand for lodging, Lowlandss and agricultural countries in the periphery zone are quickly going built-up by the person and belongings developers. While suburban development is a really complex procedure that is known to be influenced by a assortment of factors, including guess and old termlandnext term monetary values, these factors may non adequately explicate the procedure of suburban development in the survey country. A more elaborate survey is hence required in order to understand the assorted factors act uponing suburban development in the greater Dhaka country. Furthermore, hapless coordination among executive bureaus is besides responsible for the decrease observed in natural resources in the survey country. For illustration, in the Dhaka-Narayangonj-Demra ( DND ) undertaking, despite about 6000A hour angles being set aside for a gricultural production in the 1960s, the country has been used by local and migratory people for residential intents since 1990s without any blessing from the governments concerned. Cases such as this illustrate the deficiency of effectual coordination among the organisations involved in the planning and development of Dhaka. Analysis of the LULC old termchangesnext term in Dhaka over clip revealed a considerable addition in the built-up countries over the survey period ; built-up countries increased by 6132A hour angle between 1975 and 1992, which is an norm of more than 360A haA yra?’1. Similarly, built-up countries increased in size by 4422A hour angle from 1992 to 2003, more than 400A haA yra?’1, and the net addition of old termurbannext term countries over the survey period was 10554A hour angle ( Table 3 ) . When compared with other metropoliss in the part, such as Ajmer City in India, the rate of the old termurban expansionnext term in Ajmer City was 29.2A haA yra?’1 over the period 1977-1989 and 32.4A haA yra?’1 from 1989 to 2002 ( Jat, Garg, & A ; Khare, 2008 ) . Although urbanisation is by and large related to demographic old termchangenext term and economic growing ( Li, Sato, & A ; Zhu, 2003 ) , the nature of old termurban expansionnext term in the survey country ma y besides be associated with other factors such as topography, old termlandnext term usage, and transit. Close scrutiny of the old termchangenext term sensing statistics revealed that about 6132A hour angle of the urbanised country in Dhaka were antecedently either agricultural countries or H2O organic structures between 1975 and 1992. Conversely, 4422A hour angle of the freshly urbanized countries were antecedently flora or wetlands during the same period. By and large, two factors were observed to hold promoted old termurbannext term growing: ( 1 ) increased economic activity associated with the constitution of economic zones ( e.g. export treating zone ) and ( 2 ) redefinition of the metropolitan country. Between 1975 and 1992, reclassification of old termurbannext term countries every bit good as infrastructural development played a important function in the old termexpansion of urbannext term countries. For case, the nor'-west and southerly old termexpansionnext term of the met ropolis occurred in response to building of a inundation embankment in 1992 ( Fig.A 1 ) and a span on the Buriganga River in 2001. The spacial features of built-up countries have besides been shaped by the building of a figure of transit paths in the same period, as understood from historical map analysis and field visit. The old termexpansionnext term to the E and nor'-east led to the development of unplanned suburbs in the Lowlandss and agricultural countries that were antecedently located in those countries.

Another important old termchangenext term was the diminution in wetlands and flora from 1992 to 2003. In 1992, wetlands and flora occupied 28 % and 13.7 % of the entire survey country, but by 2003, these countries had declined to 21.7 % and 5.5 % , severally. Conversely, built-up countries increased in size by 37.9 % in the period from 1992 to 2003. A little addition in cultivated old termlandnext term ( 6.7 % ) was besides observed in this period. The diminution of flora and wetlands was clearly due to intensification of old termurbannext term development in the greater Dhaka country, peculiarly through the procedure of suburban development. As shown in Table 4, there has been a pronounced old termchangenext term in LULC ove r the 28-year survey period. Table 4.

The procedure of old termurban expansionnext term in Dhaka was observed to change markedly over the old ages examined in this survey ; specifically, the metropolis expanded by 6131.9A hour angle during the 17-year period from 1975 to 1992 and 4422.2A hour angle in the 11-year period from 1992 to 2003. Landsat images revealed that old termurban expansionnext term in two periods examined in this survey did non happen equally in all waies ; new developments were observed along the fringe of old termurbannext term countries every bit good as in the countries that had already been urbanized. The rapid gait of urbanisation in Dhaka means that it has non been possible for the municipal authorities to supply basic old termurbannext term comfortss to the population, which has led to a broad scope of environmental jobs. For illustration, old termurbannext term development facilitated by old termlandnext term filling has been shown to hold a negative impact on natural home ground and biodiversity ( [ Alphan, 2003 ] and [ Dewidar, 2002 ] ) . Vulnerability to temblor related jeopardies has besides increased since a major part of Dhaka ‘s recent development has taken topographic point in landfill sites ( Kamal & A ; Midorikawa, 2004 ) . In southern Dhaka, landfills have contributed to dir ty pollution, ensuing in reduced flora ( Khatun & A ; Hoque, 1994 ) . Uncoordinated urbanisation and the creative activity of landfill sites have intensified the extent of flood in the metropolis during the moisture season ( Alam & A ; Rabbani, 2007 ) , which is peculiarly critical in the western parts of Dhaka ( Maathuis, Mannaerts, & A ; Khan, 1999 ) . Flood hazard potency has been elevated due to continued infilling of H2O organic structures, wetlands and low-lying countries ( Dewan & A ; Yamaguchi, 2008 ) . In add-on, the speed uping growing of slums is impacting the metropolis ‘s physical and human environment. Harmonizing to CUS etA Al. ( 2006 ) , the slum population of Dhaka ( about 37 % of the metropolis ‘s population ) has doubled in a decennary, to make 3.4 million in 2006 from 1.5 million in 1996. The environment of these informal colonies is highly unhygienic as they are in close propinquity to solid waste mopess, unfastened drains and cloacas, embankments, a nd along railroad lines ( Islam, 1999 ) . Consequently, the people populating in slums are highly vulnerable to inundations ( Rashid, 2000 ) and they besides suffer from an acute deficit of drinkable H2O ( Akbar, Minnery, Horen, & A ; Smith, 2007 ) .Driving forces analysisLULC old termchanges and urban expansionnext term of Greater Dhaka is governed by a combination of geographical, environmental and socio-economic factors. Although population growing is the primary cause for rapid urbanisation, the part of other causes such as economic development and physical factors besides needs to be assessed. To measure the mechanisms underlying the old termchangesnext term in LULC and subsequent old termurban enlargement, following term we performed a arrested development analysis of built-up countries utilizing selected physical and socio-economic variables ( lift, incline, population and GDP ) , and presented the consequences in Table 5. old termUrbannext term country informations were extr acted from one-year BBS statistics since RS informations merely cover three old ages. To analyze the effects of incline and lift on old termurban enlargement, following term average values of incline, and lift of both developed and developing countries in the metropolis were calculated from a digital lift theoretical account. Socio-economic informations, such as population and GDP values were obtained from the decadal and annually one-year tabular arraies of the Bangladesh Bureau of Statistics ( Table 1 ) . Table 5.

By 1981, the population had reached 3.44 million. The population reached 6.92 million in 1991 and 10.7 million by 2001 ( BBS, 2001 ) . Presently, the population of Dhaka is more than 12 million with an one-year mean growing of 5 % , compared to the national growing of 2.1 % ( Bangladesh Bureau of Statistics ( BBS ) , 2005 and [ The World Bank, 2007 ] ) . The rapid growing of the old termurbannext term population has chiefly resulted from rural-previous termurbannext term migration and estimates show that more than 60 % of people in Dhaka have migrated from rural countries ( Islam, 1991 ) . Intelligibly, this addition in the population had the consequence of i ncreasing force per unit area on the limited resource-base, and significantly contributed to the old termexpansion of urbannext term countries by glade of natural flora and infilling of low-lying countries. Table 5 clearly shows that old termurban expansionnext term is positively related to population growing. Dhaka ‘s economic development is another factor that has contributed to rapid urbanisation. For illustration, Dhaka ‘s gross domestic merchandise ( GDP ) was about 11,312 million Taka1 in 1976, 129,665 million Taka in 1992 and 162,490 million Taka in 1995. Presently, the GDP of Dhaka is 354,240 million Taka and the metropolis ‘s portion of the national economic system is 19 % ( BBS, 2005 ) . The economic development associated with the roar in ready-made garments since the 1980s has had a important impact on old termexpansionnext term of the metropolis country. This economic activity has besides resulted in a big inflow of rural-previous termurbannext term migrators in the same period ( Islam, 1996 ) . In add-on, Dhaka supports more than 40 % of Bangladesh ‘s industry, farther suggesting that the economic development and industrialisation has led to a higher rate of old termurban expansion.next term The arrested development analysis revealed that GDP exercised positive effects on old termurban land expansionnext term ( Table 5 ) . As in other old termurbannext term centres, the way of old termurban expansionnext term in Dhaka has been extremely influenced by its physical scene, peculiarly its topography. The four major rivers, swamps and depressions within and around the metropolis have ever played a polar function in the development of built-up countries in the metropolis. Urbanization ab initio occurred in the elevated countries that were non affected by inundation. Once all the elevated places had been developed, the lifting demand of old termurban landnext term has been met by the transmutation of low-lying countries, vegetated countries and wetlands. The development of wetlands, for case, has led to a significant loss of natural resources and an addition in habitat debasement. The growing of belongings developers has accelerated invasion of old termurbannext term countries on wetlands and threatens biodiversity. Two geophysical indexs were used in the arrested development analysis ( Table 5 ) and found th at lift has major influence on old termurban expansionnext term while incline has non passed the important trial.DecisionsThis survey has assessed LULC old termchangesnext term and the kineticss of old termurban expansionnext term in Greater Dhaka, Bangladesh utilizing RS informations in concurrence with socio-economic variables. old termUrban expansionnext term was quantified for the last 28 old ages utilizing the post-classification comparing technique. Greater Dhaka was found to hold experienced rapid old termchangesnext term in LULC, peculiarly in built-up/previous termurbannext term countries. Analysis revealed that old termurbannext term countries increased by 6131A hour angle during 1975-1992 and 4422A hour angle from 1992 to 2003, which resulted in a significant decrease in the country of H2O organic structures, flora, cultivated countries and wetlands/lowland. The dramatic old termexpansion of the urbannext term countries of Dhaka exhibited clear spatio-temporal differences . The transition of H2O organic structures, flora and low-lying countries to old termurban landnext term has caused extended and varied environmental debasement in the survey country, and the exposure to implosion therapy and the growing of slums have been the chief negative results associated with the rapid old termurbannext term development. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Integrated usage of GIS, RS and socio-economic informations could therefore be efficaciously used to understand the spatial and temporal kineticss of LULC old termchanges.next term The reading and categorization of RS informations were utile for gauging the rate and spacial form of the old termurban expansionnext term in Greater Dhaka of Bangladesh. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms.

Double Possessive

Double Possessive Double Possessive Double Possessive By Maeve Maddox A reader asks, What are your thoughts on double possessives? For example: Friends of Sues   Friends of my aunts Friends of his Friends of hers Friends of theirs Friends of mine You will find the double possessive question and animated discussions of it on hundreds of language sites all over the web. It remains popular because it has no simple answer. First let me say that the reader’s fourth example, â€Å"friends of her’s,† would never be an option for anyone: the pronoun must be spelled either her or hers. The â€Å"double possessive† is so called because the preposition of, the possessive pronouns hers and theirs, and the ’s all signal possession. The construction is also called â€Å"double genitive† and â€Å"post genitive.† The objection to â€Å"friends of Sue’s† and â€Å"friends of mine† is that the of ought to be sufficient. Granted, â€Å"friends of Sue† is a reasonable option, but no native speaker is likely to say â€Å"friends of me.† The intractability of the question lies in the fact that in some contexts the double possessive is idiomatic. As far as a rule can be stated, it is this: Generally, what follows the of in a double possessive will be definite and human. For example, we might say â€Å"friends of Sue’s,† but not â€Å"friends of the university’s.† Another guideline is that what precedes the of will usually be indefinite. For example, â€Å"a friend of Sue’s.† When the preceding word indicates something definite, the second possessive is dropped: â€Å"the best friend of Sue,† â€Å"that friend of Sue.† On the other hand, one might say, with some emotion, â€Å"That dog of Sue’s is a nuisance.† Sometimes the double possessive is needed to avoid ambiguity. Compare: The mansion contains portraits of the owner. The mansion contains portraits of the owner’s. In the first sentence, the portraits are of the owner (i.e., they present a likeness of the owner). In the second, the portraits may be of anyone, but they belong to the owner. The most practical rule for writers is to avoid having two possessives in formal writing. If they occur, rewrite the sentence. As for informal use, the double possessive is idiomatic in English and has been for a very long time. Want to improve your English in five minutes a day?

A Discussion on the Significance of the Emancipation Proclamation

A Discussion on the Significance of the Emancipation Proclamation Life before and after the Emancipation Proclamation was quite different in the lives of African American slaves during the time it was put into effect. Before the Emancipation Proclamation was initiated by President Abraham, African Americans were seen as less than humans, considered as property, mistreated, and endured various hardships. The newly freed slaves would continue to experience such things even after the proclamation. Slaves did not have the all the privileges and freedoms that Whites had and that we have today. Contrasting with this, was what life was like for them after the Emancipation Proclamation and in the later years following the Civil War. For once the war was over and the Emancipation Proclamation was established, African Americans could now live independently and lead almost what was normal and productive lives. But even after the Civil War, blacks would continue the long and hard fight for their freedoms and rights. In this essay, I will give a brief overview of the Civil War, what life was like for the slaves before the war, the events that led up to this historical incident, the Emancipation Proclamation and its significance, the life of a slave after the Emancipation Proclamation, and what slavery means to our society today. The American Civil War, lasting from 1861 to 1865, was fought between what was known as the Union, the North, and the Confederacy, the South. America had fought for its independence from Britain several years before. Now, it was time for African Americans to also fight for their independence and break the yoke of bondage that their captors held them in for so long. The Union, was against slavery and wanted to abolish it, while the South fought to continue it. The Civil War originated on the concept of slavery. The Southern states viewed the abolishment of slavery as a violation of their rights and was unconstitutional. But the Civil War was not solely about slavery. Other differences and disagreements that two sides had, such as politics and the debate on secession, slowly built up the tension that had already existed between them. Because the South feared for their rights and thought those rights were being violated through the government’s decision to end slavery, they felt the need to react to protect themselves. Afterall, if the central government acted against the South’s wishes and defied the Constitution, they would soon continue to do so in the future. President Lincoln was elected around that time and before he was even inaugurated several states had left the Union. Beginning in January, 1861, seven slave states left the Union. The states included: South Carolina, which was the first to secede from the Union and form the Confederacy, Mississippi, Alabama, Georgia, Texas, Louisiana, and Florida. Just months later, Arkansas, Virginia, Tennessee, North Carolina, would also secede from the Union making the total number of states that had left, eleven. War eventually broke out when the two sides could not find a compromise nor solution to their problems. The South continued in its rebellion against the Union, which held the central governing body of the nation. Several states had seceded from the Union and set up their own system and governmen t, dividing the country into two. The war officially started on the morning of April 12, 1861, when the South attacked Fort Sumter, a U.S. fort in South Carolina. After rebelling against the Union for so long, the South had now pulled the last straw, and the war had finally begun. The Civil War was just another one of the wars that set the stages in the changes the nation would undergo and ultimately lead up to where we are today. The life of a slave before the Civil War was a lot different after the war though things did not start to improve immediately. Slaves were forced to work long and hard hours in the heat, were malnourished, beaten, and underwent many more difficulties. Some worked on vast plantations, toiling in the fields, picking cotton and more, while others worked on plantations that were not as big. Some slaves had harsh and brutal masters, while others had masters who treated them as one of the family. But regardless of whichever master the slave had, the slave was still considered a slave, though those with masters that were not so harsh received better treatment than those who did not. Slaves had no rights or say so in American politics nor any other area in the decision making of America or their masters. Slaves were not even considered as people, but as property. The founding fathers and writers of the Constitution considered slaves as threefifths of a person, thus African Americans were per ceived and treated as inferior to the Whites. One reason for why Africans were selected out of every other ethnic group was supposedly for religious reasons. Perceived as pagans and barbarians in their homeland, the Whites believed that enslavement would â€Å"save† them. It would also be easy to kidnap and force them into slavery knowing that they had no support system nor anyone who would fight for them. Isolated and left to fend for themselves, several thousand Africans were forced on to slave ships where it would take them to their new home in which they would work as slaves. The idea of slavery seemed like the greatest choice for the growing American economy at that time and was more convenient than having indentured servants. Indentured servants often worked between four to seven years and were paid in the forms of a place to live and other basic necessities. Indentured servants were also able to gain their freedom after their time of servitude expired. Because slaves could not demand any form of payment like indentured servants could, slavery was chosen as the best option, with Africans being their main target. The events that led up to the Civil War each occurred slowly but continuously. In What Caused the Civil War? Reflections on the South and Southern History, Edward L. Ayers discusses how Americans today depict the Civil War and its causes. He goes on to address questions of how modern Americans view the Civil War. As for the cause of the Civil War, he allows that the short answer is, indeed, slavery. However, he cautions that it required the interaction of many other factors to turn the tension over slavery into a great Civil War. Rather, slavery was â€Å"the key catalytic agent in a volatile new mix of democratic politics and accelerated communication, a process chemical in its complexity and subtlety† (142). Those two words, â€Å"complexity† and â€Å"subtlety,† are key terms in Ayers’ understanding both of the Civil War and of all of Southern history, and he repeatedly cautions the reader against settling for â€Å"simple explanations for complex prob lems† (143).1 Though slavery might have been the central cause of the war, it was not the only cause. While there are various debates about what specifically caused this great event in history, slavery was just one of the many factors that caused the war. Failure of the slave states to find a common ground or compromise with the free states caused the two groups to clash. This divided what was supposedly the United States and before long, the tensions that had built up for so long between the North and the South had finally escalated into a grand blowout between American and itself. This blowout would last four years. The Emancipation Proclamation was instituted on January 1st, 1863 by President Lincoln. President Lincoln determined by the fall of 1862 to move against slavery. By that time, the political risks of inactivity equaled or exceeded those of appearing rash and desperate and freed the President to act on his antislavery principles. On September 22, 1862, he warned the Confederates that unless they ended their rebellion he would move against slavery on January 1, 1863, and with the onset of the new year he made good his promise, declaring that â€Å"all persons held as slaves† in rebel areas â€Å"are, and henceforward shall be, free†; he added that â€Å"such persons of suitable condition will be received into the armed service of the United States.2 This statement implies that President Lincoln used the concept of ending slavery as way to get the attention of the South and to end their rebellion. Therefore, it also implies that the Civil War was not just about slavery, bu t subduing the Confederacy who had rebelled against the U.S. and started their own agenda. During that time, in each law that addressed slaves and slavery. Congress moved toward freeing slaves and limiting slavery. Congress also indicated a willingness to emancipate various groups of slaves as war policy.^ Indeed, those laws gave the President the power and duty to seize and liberate the property, including slaves, of those who were engaged in war against the United States or were disloyal to the United States. President Lincoln issued the Emancipation Proclamation against that legislative backdrop. Given such legislation. President Lincoln may have had the constitutional authority to issue much of the Emancipation Proclamation under his take care authority.3During the time of the Emancipation Proclamation, the nation had now been in its third year of engaging the South in the Civil War. The Emancipation in itself was a source and symbol of freedom to the African slaves, though they had a long road to take until they could live a normal life in the land of which they were now free. Though the Emancipation Proclamation freed the slaves in the South, freeing the slaves was not President Lincoln’s original plan and intention in instituting the proclamation. Knowing that he had to retain the loyalty of the slaveholding border states, President Lincoln declared that his paramount intention was to save the Union, not to free the slaves. In this case, Lincoln’s initial concern was preserving the Union which was now torn in two by the issue of slavery. It was only by settling this issue that the country would be put back together again. â€Å"the Proclamation had a powerful symbolic effect. It broadened the base of the war and turned it into a fight for freedom as well as union. It gave the Northern cause the weight of a moral crusade.5 Thus the Emancipation Proclamation allowed the newly freed slaves to enjoy freedoms they were forbidden from having prior to being set free while it did not provide for them the privilege or rights the white citizens had. The Reconstruction Era began in 1865, following the Civil War, and lasted until 1877. The Reconstruction Era marked a turning point in history in the lives of the newly freed slaves. It also was only the beginning in the African American’s long road to freedom and independence, for after the Civil War, they were still not yet treated fairly and as equals to the Whites. Clearly a racist image of Reconstruction as a failure, ignoring the eras accomplishments, combined with the Jim Crow laws, the violence that accompanied them, lynching, and convict leasing, all contributed to the humiliation and terror of African Americans†¦6 This statement implies that even after the Civil War, African Americans were still mistreated and persecuted. For though they had been freed, they would pay a high price for their freedom to the angry and enraged South who resisted any form of Reconstruction. The postemancipation period had brought freedom and a new way of life in the lives of former slaves, but it also brought with it hardships, persecution, and oppression. But, the pu rpose of Radical Reconstruction was to give African Americans equality. That goal was not immediately achieved in the years following the Civil War. Radical Republicans sincerely wanted to help the former slaves, but they made two serious mistakes. They assumed that giving southern blacks the vote would enable them to protect themselves politically. Second, Radical Republicans, although willing to give millions of acre of land to railroad companies, were unwilling to give land to the freed slaves so that they could become economically independent.7 This statement in itself speaks of how blacks were not able to become completely independent though they were free and able to do and go wherever they wished. They would continue the long and hard fight before their hopes and dreams would become a reality. For though they were finally free, African Americans would yet suffer from what the war had left behind. The defeat of the Confederacy brought freedom, but also uncertainty. Without edu cation and jobs, freed people faced continued poverty.8 Many lost their lives, underwent many difficulties, and mistreated in the process of that fight. Yet, they all stood their ground and fought bravely.. It was individuals such as these that made their greatest mark on history and are heros to this day. The Reconstruction Era, the aftermath of America’s war from within, was the second period of time in which America underwent restructure, with the first being the Revolution. America would continue this process of restructure even after the Reconstruction era had ended. Though the war was over, it had left a messy mark, one which was going to take some time to clean up. Many lives were lost on both sides during the bloody and gruesome war. Cities and towns laid desolate and in ruins, with bodies strewn everywhere. The North had won the war, but paid a high price. Yet the South was now defeated, thus, they finally gave up and surrendered. Lincoln later pardoned the South and the nation was unified once more. The end of the Civil War may have brought closure to the death and devastation of the battlefield, but it opened a Pandora’s box of social and economic problems. The magnitude of disorder and suffering was tremendous: abandoned lands, lack of food and clothing, the many thousands of displaced persons, successive crop failures, and the transition from slave to free labor on the part of millions of black people.9 With the Civil War now over, new social and economical problems had arose for America. One of the greatest periods of time in America’s growth and rebuilding, the Reconstruction era helped shape American and its future. But while the Reconstruction era opened a new area of problems in the develo ping nation, it also brought about new opportunities and a means for African Americans to support themselves and start a new life. It was during this time that the Freedmen’s Bureau was established, helping to assist both blacks and whites who were struggling to survive. The bureau fed the hungry, provided medical care, shelter, and more to those who needed it to both poor Blacks and Whites. During the Reconstruction era, the concept of education was also open to African Americans, of which it had been forbidden for slaves before then. In the past, slaves would get into severe trouble if they were caught reading or performing any other educational activity. This could also mean trouble for their masters as well if they were caught educating the slaves. After the Civil War, those laws no longer applied. The fuller freedom Quarles speaks of represents a psychological break from the chains of slavery. As the legal chains of slavery were released via the emancipation proclamation , education became the principal source of release from the psychological chains of slavery.10 The emancipation had set slaves free physically, but now through education, African Americans were set free mentally. Something that was strictly forbidden and off limits to the former slaves, was freely available to them now. This also enabled them to become more independent because they knew how to support themselves and their families. This, along with the beginning of African American’s fight for civil rights were just some of the changes that the post Civil War and Reconstruction era brought about. Though a slow and difficult process, it eventually paved the way for life as we know it now here in America. Though African Americans are no longer enslaved today, its effects are still present in our society today. The false perception of blacks being inferior and mediocre and the issue with racism is still common, though it may not be as apparent and strong as it was back then. But just as this prejudicy divided and almost destroyed an entire nation, it is still destructive and divisive in our society today. Sharon E. Davis speaks about racism and its effects in her article, The Oneness of Humankind: Healing the Racism Today: The compound problem of race and other issues such as poverty only can be resolved with the acceptance and understanding of our human oneness. Our shared humanity is the glue that holds us and our future in its grasp. We are familiar with how families grow into clans, then tribes, and tribes into kingdoms and then states/nations. The pressing need is to be unified in all essential aspects of human life, yet infinite in our diversity. . . . The deep roots of racism ar e anchored in the false belief that one race or culture is superior. Further, the principle of the Oneness of Humankind means that not only White people can be racists. Given the same history and circumstances, any group of human beings may behave in similar ways. 11 No one race or ethnic group is superior to another. However, it is when we begin to believe and live this concept, that we grow farther apart and in opposition to one another. When we refuse to accept people for who they are and only perceive them as different then we miss really miss out on what matters. In fact, refusal can be not only harmful for the other person, but us as well. As racism was divisive back then and almost ruined a nation, it is still divisive and destructive today. One of the main causes of the Civil War was disunity, greed, and just plain selfishness. Perhaps, if the two sides had found a way to work through their problems, the war could have been avoided. It is critical that we perceive others the same way we perceive ourselves. For if things were reversed, how would we feel?
