The topic of nutrition of the elderly

The topic of nutrition of the elderly The purpose of this literature review is to research the topic of nutrition of the elderly, and to discuss my findings. I will be researching this subject using tools such as athens, and using websites such as google scholar, ovid and internurse. I have chosen to use articles and reviews from the past ten years as I feel they will bring the most up to date nursing care techniques and the most reliable research into the subject. Nutrition of the elderly is an important area of nursing care and should not be taken lightly. It is important in nursing care to assess patients nutrition, as if taken care of it can optimize the general well being of the patient. Malnutrition is the main worry when focusing on elderly patients nutrition, as 40 to 60% of older adults who are hospitalized are malnourished or at risk of malnutrition. This statistic is rather high, meaning that the correct nursing practise is not always used. In this review I will be looking to find the reasons behind this and how the care of these patients can be increased to its full potential. When we look at nutrition we have to consider why it is that elderly patients are so different compared to everyone else. Many questions arise when we look at this for example do they have different eating habits, is there a physiological problem or even is there a psychological problem. The answers to these questions can always be yes in relation to the elderly and we must look further than these general questions, and study the literature of the subject to fully become aware of the correct nursing care to correctly assess and treat this problem. A review by Finch et la (1998) shows that a the majority of the elderly population, not requiring hospitalization, are well nourished and have a good intake of all the correct vitamins, minerals and calories. However what is of more importance in this review is the elderly patients who fall without this category including patients whose nutrition does affect their health and have physical and or mental problems which lower their nutritional intake. A report by COMA (DH, 1999) stated that diet deficiencies in the elderly, most noticed in calcium levels and recommended that current practice of fortifying flour with calcium should continue the same. That same survey also highlighted the low levels of Vitamin D in the elderly which, together with the low levels of calcium gave concern for the increased incidence of osteoporosis found in the elderly population. Another review highlighting deficiency in different areas for the elderly. (Steele et al., 1998) point us to the fact that many elderly patients do not have a good dentition. This obviously can have a massive impact on their nutritional intake and in their choice of food and ease or difficulty of eating it. They also found that those of the elderly who had their own dentition did have a measurable better nutritional and mineral intake than those who did not. Those with poor teeth tended to eat significantly less fruit, nuts and food generally that was hard to chew, meaning they missed out on vital natural vitamins and minerals. All of these facts drawn from literature show us that the nutrition of the elderly is an important and special group. I will now look into further literature to show these specific groups in the elderly population which lack of proper nutrition can affect. Malnutrition is a main concern in nursing practise with elderly patients, so when looking at it we must be fully aware of what the term means. A review by DiMaria-Ghalil (2005) shows the definition of malnutrition. Any disorder of nutritional status, including disorders resulting from a deficiency of nutrient intake, impaired nutrient metabolism, or over-nutrition. Reuben (2005) shows us that malnutrition can be brought on by many things in the elderly population such as dietary intake, isolation, chronic illness, and physiological changes. The routine for the correct nursing care with elderly patients is essential and must be followed for every patient so that no patient is misdiagnosed. During the routine nursing assessment, any and all alterations in the general assessment areas that may influence the patients factors of intake, absorption, or digestion of nutrients should always be further assessed to make sure if an older patient is at a nutritional risk. These areas include the following. As stated by a review done by the University of Texas, School of Nursing (2006) a typical assessment should be done including their present history, past and medical history, and an assessment of their current symptoms. A note of their social history should be taken into account. Any drugs the patient may be taking which can interact or affect the patients nutrient intake and absorption. Boullata, J (2004) stated that drugs can affect and modify the nutrient needs for the metabolism of older people. It also stated that factors such as restrictive diets, changes in eating habits and diet, alcoholism and chronic disease with long term drug treatments can all affect the nutrient intake and reactions in an elderly patient. The fourth area that should be taken into account is the patients functional limitations. Boullata, J (2004) showed that patients with functional limitations can be at risk of malnutrition for many reasons, whether it be a disability restricting their movement, and even a psychological problem such as dementia which can restrict the patients ability to eat in different forms. Next that will be checked on the nursing assessment will be the objective assessment. This will include a physical examination of the patient with emphasis on things such as an oral exam, loss of body fat, dysphagia, bmi and muscle wasting. Also DiMaria-Ghalili (2005) showed that for a more in depth idea of the patients dietary intake can be gathered by a documented three day calorie count using a food chart for the patient. This will help gain some more information for the patients nutrition. Also one of the main things used for every patient in hospital which is malnourished or at fear of malnutrition is the nutrition risk assessment tool. Both DiMaria-Ghalili (2005) and Salva, A (2004) go on to state how this tool is vital and very useful at assessing as it determines the risk by looking at the patients bmi, history of weight loss, psychological stress, or acute disease and dementia or any other conditions which could affect their dietary intake. By using all these it can help come up with a individual score for the patient, and with this score we can evaluate if the patient is malnourished, and what further action can be taken to benefit the patient. This will include things such as referring the patient to the dietician, and or the speech and language therapist. There are many nursing strategies we can use to make sure that any patient that is malnourished can be assessed and monitored to help improve their health and general well being. As I previously noted by Salva, A (2004) referring to the dietician if the patient is at risk for or has under-nutrition. Another useful collaboration for nursing care is to consult the patients medication and review it for possible drugs that can affect the nutrient interactions. Also consulting with a multidisciplinary team specializing in nutrition can benefit the patients all over care as it is more specific to their needs. There are also methods that the nurse can use in the patients daily routine to help the patients efforts in becoming nourished. By alleviating a dry mouth the nurse can help the patient become more willing, and wanting, to take diet and fluids. This can be done by avoiding any foods or drink which can further cause a dry mouth, such as, tobacco, dry and bulky foods, and highly acidic foods. Also to encourage frequent sips of water and keeping lips moist will help the patient to become more hydrated and more comfortable, which, will make them more willing to eat and drink. Margetts, B (2003) also states how important it is to maintain an appropriate nutritional intake for an elderly patient. It goes on to explain how the daily requirements of older adults includes thirty kcal per kg of body weight and 1g of protein per day, with this no more than 30% of calories from fat. It also goes on to explain all requirements will differ depending on the degree of malnutrition and physiological stress the patient is in. A nurse can take this into account when treating a patient in their daily routine by improving the patients oral intake, of which there are many ways of achieving. Souter, S (2003) shows that a patients meal times are important as it will determine how much food the patient has consumed and whether or not they will need assistance with eating from a member of staff. A nurse can go further than this by asking the patients family members to visit during mealtimes making it a more relaxed atmosphere for the patient, meaning they will feel more relaxe d and willing to eat, and for those who need help eating, their family members can assist them which may be more comfortable for them. A nurse can also ask the family members to bring in favourite foods of the patients from home to help in the intake of the patient. With foods that they regularly eat and enjoy, the patient will be more likely to partake in meal times and even snacking between meals, increasing their intake overall. If this is done for a patient the nurse must be aware of the foods the patient likes, and or can handle so that they can supply the patient with what the need and want for their duration in hospital. The nurse can also take into account the nutrients that the patient needs, therefore can suggest small and frequent meals which contain these to help to regain and maintain weight. The nurse can also help a patient with their mouth care such as helping patients with their dentures before food is served so they are ready to eat when it arrives. Souter, S (2003) showed that another way to improve meal times is to create a good environment for the patient. By removing things such as bedpans, urinals, and sick bowls can help to create a positive and clean place for the patient to eat, so nothing is putting them off or distracting them from their food. Also Souter, S stated that any patients who tend to feel ill during meal times can be administered antiemitics on a schedule that will help to lower and diminish the likelihood of them feeling nauseated during their meal. Shahar, D (2001) also shows that with certain patients who are mobile enough to sit in a chair rather than their bed should be placed in such as it is more comfortable for them to eat their meals. The nurse can also create a relaxing atmosphere for patients who needs assistance in eating their meal by sitting at the patients eye level and making eye contact during so that they feel they are not just a chore for the nurse. It is also important for nursing staff not to interrupt patients during meals for drug rounds and procedures as it may distract the patient from their meal and even make them feel, depending on the medication, tired or nauseated which will stop them from eating a sufficient amount for themselves. Nursing staff can also provide specialised nutritional support for certain patients depending on their requirements. The Nutrition Screening Initiative (2002) states that a patient should be started on nutritional support when they cant or wont eat an adequate amount to ben efit themselves. The patient must be reviewed regarding if they already use artificial nutrition and hydration. This can be done by providing oral supplements to the patient. These supplements are not to replace meals, but to be given during the day between meals as shown by Wilson, M (2002). Also it is stated by American Society of Anaesthesiologists that by placing elderly patients as early in the day as possible for tests or procedures it will decrease the length of time that the patient is nil by mouth and not allowed to eat or drink. Meaning less time is wasted where the patient could have been receiving a nutritional diet and fluids. By looking at all this literature we can see that

Extracurricular activity

But today some universities are applying for the student participating in extracurricular activities after classes at school to improve the effectiveness of teaching and learning. So some study is done to show the benefits of extracurricular activities. At the beginning of the twenty-first century, many colleges and universities have a broad educational mission to develop the â€Å"whole student. † On college campuses, extracurricular involvement is a key tool in this personal development. For the ajority of college and university students, involvement in extracurricular activities plays an integral role in the collegiate experience.Students become involved in extracurricular activities not only for entertainment, social, and enjoyment purposes, but most important, to gain and improve skills. Youth problem behaviors, such as truancy, violence, and substance use, are alarming to parents, teachers and youth alike. These behaviors disrupt the learning environment and lead to seri ous social and economic problems. Some experts have argued that rather than trying to prevent individual problem behaviors, parents, chools and communities should work towards building a youth's ability to resist the lure of problem behaviors (Dryfoos, 1990; Werner ; Smith, 1992).As youth develop, they need positive settings that offer the opportunity to build these important internal resources (Hawkins ; Weiss, 1985). Researchers and teachers have long suggested that extracurricular activity participation can be an important source of positive influence in the lives of youth (Holland ; Andre, 1987). This Fact Sheet will explore how youth participation in extracurricular activities can encourage positive youth development. . 2. Objective The importance of extracurricular activities on college campuses is well established.The primary goals of extracurricular activities focus on the individual student level, the institutional level, and the broader community level. These activities ex ist to complement the university's academic curriculum and to augment the student's educational experience. According to a 1993 article by Alexander Astin, almost any type of student involvement in college positively affects student learning and development. Extracurricular activities provide a setting to become involved and o interact with other students, thus leading to increased learning and enhanced development.Specifically, a student's peer group is the most important source of influence on a student's academic and personal development. By identifying with a peer group, that group may influence a student's affective and cognitive development As the development of the well-rounded individual is a principal goal of extracurricular activities on college and university campuses, the numerous experiences these activities afford positively impact students' emotional, intellectual, ocial, and inter-personal development. By working together with other individuals, students learn to neg otiate, communicate, manage conflict, and lead others.Taking part in these out-of-the-classroom activities helps students to understand the importance of critical thinking skills, time management, and academic and intellectual competence. Involvement in activities helps students mature socially by providing a setting for student interaction, relationship formation, and discussion. Working outside of the classroom with diverse groups of individuals allows for tudents to gain more self-confidence, autonomy, and appreciation for others' differences and similarities. Students also develop skills specific to their career path and imperative for future job success.Students have opportunities to improve their leadership and interpersonal skills while also increasing their self-confidence. Extracurricular involvement allows students to link academic knowledge with practical experience, thereby leading to a better understanding of their own abilities, talents, and career goals. Future employ ers seek individuals with these increased skill levels, making hese involved students more viable in the Job market. Specifically, participation in extracurricular activities and leadership roles in these activities are positively linked to attainment of one's first Job and to managerial potential.Student involvement in extracurricular activities also positively impacts educational attainment. Ernest T. Pascarella and Patrick T. Terenzini's 1991 research indicates that extracurricular involvement has a positive impact on attaining a bachelor's degree and on educational aspirations. Students who are actively engaged re more likely to have higher educational ambitions than uninvolved students. Finally, extracurricular activities focus on institutional goals, such as building and sustaining community on campus as well as student retention.As campuses become more diverse, students desire an environment in which they feel connected to others and to the university. Extracurricular activit ies provide a place for students to come together, discuss pertinent ideas and issues, and accomplish common goals. Within this community, where students feel comfortable with one another, learning and evelopment are enhanced and student retention is positively impacted. According to Vincent Tinto's 1987 research, students will be more likely to persist in college if they feel they have had rewarding encounters with a college's social and academic systems.Through extracurricular participation, students frequently interact with peers who have similar interests, providing social integration into the college environment. As a result, involved students view their college years as a positive experience and feel they are a vital part of the university, resulting in higher retention rates. 1. 3. Organization Chapter 1 of this study introduced the problem statement and described the specific problem addressed in the study as well as design components. problem addressed in this study.Chapter 3 presents the methodology and procedures used for data collection and analysis. 2. LITERATURE REVIEW This chapter will provide discussion some of the positive effects in student development based on participating in extracurricular activities. In addition, this chapter will also describe how extracurricular activities can effect personal, social and academic development in a positive manner. 2. . Introduction 2. 1 . 1. Definition: â€Å"Extracurricular activities are those that fall outside the realm of the normal curriculum of school or university education, performed by students† (Wikipedia).Extracurricular activities are opportunities to engage in extensions of academic activities and/or non-academic activities under school auspices. In special circumstances, for example, when there are budget or scheduling constraints, extracurricular activities may provide experiences that would otherwise be offered within the school day. (wiseGEEK. org) Extracurricular can be valuable experience. If you have a career or study interest that you can pursue outside the classroom, take advantage. Think you might be interested in medicine? Try volunteering at a local hospital.Are you destined to be a writer? Join your school's newspaper or literary magazine. These activities can help give you a strong foundation should you decide to pursue them further, academically or professionally. (The Princeton Review) 2. 1. 2. Extracurricular types: These activities are generally voluntary as opposed to mandatory, non-paying, social, philanthropic as opposed to scholastic, and often involve others of the same age. Students often organize and direct these activities under faculty sponsorship, although student-led initiatives, such as independent newspapers, are common.There are many types of extracurricular activities: Athletics, Clubs, and Competitions†¦ 2. 2. Benefits of Extracurricular Activities: There are many schools today that provide a lot of extracurricular activit ies. Some occur before school, some after school, and a few may even take place on the weekends. While some people are a bit dubious about participating in extracurricular activities, these activities actually bring with students many benefits. Allowing tudents to get involved in extracurricular activities at school is a wise choice, and it can be very important in helping them to develop many working skills, people skills, and more.Here is a closer look at some of the benefits of extracurricular activities for students in university 1) Learning Time Management and Prioritizing Esteem One great benefit of students being involved in extracurricular activities is that need to learn how to control a variety of different tasks in school & life as well, and getting involved in these activities can give them some practice at it. 2) Getting Involved in Diverse Interests Getting involved in extracurricular activities also allows students to get involved in diverse interests. It is important for students to be very diverse in their interests.These activities allow them to explore various interests that they may have. 3) Learning About Long Term Commitments This is another excellent benefit. Students learn about long term commitments when the Join one of the activities or clubs. They commit themselves to that activity for a period of time. If they have some troubles which they must try to solve for keeping up to their end of the deal, they will learn how to overcome difficult in any ase. If not, no doubt they'll hear about it from their peers and perhaps even teachers when they give up. ) Making a Contribution Extracurricular activities allow students to make a contribution in some way. It shows that they are getting away from Just thinking about themselves and contributing to something else. They will be taught about receive ; giving. 5) Raises Self-Esteem There are many students that feel worthless or that there is nothing they are good at. Everyone wants to find some thing that they are really good at, and extracurricular activities provide them with a way that they can get involved in omething and really shine, giving their self-esteem a boost. ) Building Solid Relationship Skills Students need to get involved in social activities and learn how to appropriate act in social situations and these activities give them a chance outside of school to do this, while they are still being supervised by adults. 7) Looks Great on Jobs Applications Another benefit of Joining extracurricular activities is that it looks great on Job applications. Most employers not only look at grades, but they take a look at extracurricular activities that students are involved in while they are in university.They want to see that students are getting out there and doing more than Just book work. The activities that teens are involved in reveal a lot about them, and definitely will say something to your boss in future.

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.

A Farewell Of Arms By Ernest Hemingway - 1845 Words

Ernest Hemingway, author of A Farewell to Arms, created a classic but controversial love story banned in Italy as well as parts of the United States, for its candid brutality. While many authors during the Roaring 20s chose to focus on the sacrifices and valor of World War I, Hemingway wrote his novel from a different but realistic perspective. As a World War I veteran himself, Hemingway based his novel off of his experiences in war and from his own life to influence the romantic relationship between Catherine Barkley and Lieutenant Frederic Henry. Choosing to break away from the social norm, Hemingway decided to incorporate literary forms to shed light on important factors individuals during this delicate time period ran from, after a†¦show more content†¦She first handily witnessed as well as suffered through pain, but was willing to assist without wasting any time by claiming that she was not qualified to do help. Critic Robert Warren wrote, â€Å"In this novel she emerg es as the truly heroic figure of the book. A model of courage and stoic self-awareness, Catherine is determined to forge a meaningful and orderly existence if only temporarily in a world in which all traditional notions of meaning and order has been shattered† (Warren, Robert). During the delicate time period of his life where vulnerability was high, he experienced losing a dear one close to him throughout his childhood, his father. He along with many others lost the ones they love to a harsh environment known as reality. Hemingway’s beliefs stated that no one could escape death as nature would destroy all in its path, but one could seek comfort to escape the reality of loss. Through the use of a minor character, Rinaldi, Hemingway was able to depict the sources of comfort individuals turned towards after World War I. Rinaldi, perceived as a competent, good-natured, masculine character who was an unbelievable ladies’ man, was seeking a source of comfort from the countless of wounded men he operated throughout the book, â€Å"This war is terrible, Rinaldi said.

Consumer Preference and Willingness System †MyAssignmenthelp.com

Question: Discuss about the Consumer Preference and Willingness System. Answer: Introduction Local production of food is able to generate more income locally along with number of employment opportunity. Most food id produced thousands of miles from where it is consumed needing specific energy consumption for the purpose of managing, storage and transportation and out coming in specific waste of food from spoilage during its journey. It is the report which will be focusing on the Bentley Beverage services which mainly deals in Western Australian premium locally produced products such as food and alcohol. It is a case study analysis in which case study is related to the Australia premium locally produced foods and I will be appointed as a consultant to provide the right guidance for improving the condition of the company. There are so many things which are required to be observed while expanding the business globally (Mugera, Amin, Michael, and Emma, 2017). The main branch of the company is situated in Perth and it has branches now Melbourne and Brisbane as well. It will focus on an improvement in the company by enhancing the productivity of the employee. The situation of BYOD will be discuss and the importance of currency information and really data information regarding Bentley Beverage services. The role of IT services in the company is major and it is vital for the company to give proper attention to this department. The advice and suggestion will be made on various situations which may bring the positive environment within the organization. The business process and management should be proactive and effective so that all the relevant information regarding inventory and data can be collected easily. The current situation of the company presents lack of business process and management. Bentley Beverage Services has expanded its business in effective manner and it is required for the business to have the entire data regarding income and expenditure in relevant manner. Customer representatives are hired as contract basis and they have to investigate about the stock and explore of the demand of the customer by travelling. I have been called in the company as a Consultant and as per my consideration it is important to must have look to the inventory system. As system of company has expanded globally and the services of Bentley is go beyond from locally which is very appreciated for the company. It is required for the company to keep focus on the business process and management for establishing the corrective way for deliverin g the products and managing the stock in various sites such as locally and globally (Carter, Tinggi, Yang, and Fry, 2015). Business process A business process is considered as the collection of the connected tasks which search their last point in the delivery of the products and services to a customer. It is a collection of activities which is necessary for the organization to attain the determined goal in certain period. It is a series of certain steps which is required for the company to b followed. It involves shipping products, updating information of the employee, marketing budget, details of order and invoicing. I would suggest to the owner of the company to apply the certain steps of business process to provide the required information to the customer service representatives. Orders are lodged in a central system but are dealt with locally by the relevant office dependent upon the product. As per my opinion, I would advise to the owner of the company to follow the business process such as a product assembly process, a quality assurance process, an invoicing process and a billing process. To improve the efficiency of the business process, the owner of the company should implement the various tools for resolve the challenges of business process such as management dashboards, verification and error handling, integration wizards and collaboration tools (Van, 2015). Management is the key tool for the growth of the company and I would suggest to the owner of the Bentley Beverage services to adopt the operational and tactical management to handle the different warehouses holding stock and managing order completion. The business has expanded and started to deliver the products globally. Customer service representatives move from one place to another to explore the latest trend of the market (Hammer, 2015). Operations management defines the business practices of administration to build the upper level of efficiency within an organization. It involves the store operation management which is the life blood of the business. The owner of the company should hire the store manager in various departments who should be qualified and able to handle the various details regarding the inventory system so that in the time of requirement real data could be available with pricing details and location. It would be good for the business and able to reduce the piecem eal application. The food products are sensitive and the Bentley produces the local products that is why it is vital for the other stores of the Bentley service to give the proper information about the remained stock and required product so that customer would not go with dissatisfaction. Tactical management is able to allow a manager in a business environment to opt the best strategy or tactics for every situation that rises, rather than following a certain standard procedure. I have analyzed through case study that Customer representatives are required to deal with both producers and sales queries as well as scan the marketplace for new products. The all customer service representatives are situated in the head office of business for maintaining the close relationship with the supplier. Tactical management would be helpful for the business to take step as per real condition because it is the services of food and alcohol which is reliable upon the real situation (Van, William, Jen, and Peter, 2014). Governance involves the rules and policies so I would recommend to the owner for making business policy and laws in an efficient manner. Mobility and BYOD issues The concern of owner regarding mobility and BYOD issues related to security and risk are genuine because the customer representatives were initially employed on a contract basis whilst the business grew which resulted in a BYOD situation. Bring Your Own Device is also called a workforce mobility because it is considered as one of the most complex development due to its introduction of huge risks to data loss and data protection. Although BYOD is eligible to provide the greater flexibility and enhance the productivity along with that it has a specific influence on the IT model. It is an attractive business model but it has numerous risks embedded with it. Owner of the business has the concern about the risk of data leakage, exploits vulnerabilities, mixing personal and business data, poorly cared of devices and IT infrastructure. The workforce of the business has expanded and due to its the floodgates of data leakage and threats may open up. As the Customer service representatives are working in different place and they are connected with mobile phone and tablet (Astani, , Kathy and Mussie, 2015). I would recommend to the owner of the business to execute acceptable policies and procedures that should be able to clearly communicate the boundaries. Owner of the business should offer a secure and reliable internet experiences. The customer service representatives are often travelling and require good mobility and data in real time. That is why it is required for the owner of the business to prevent the data of the business initiate to launch a VPN which permits access that the data being transferred from the mobile device to your IT network is encrypted and permitted. The employees are contract based and they must have been signed thee paper which is addressed the legal terms of the business. Obviously, they are traveling from one place to another that is why they are required the real time data but the concern of owner is correct on his own way. Therefore, the owner of the business should invest in the Enterprise Mobility Management (EMM) software so that he makes enable himself to monitor and then detect risks before they have a disastrous consequence (Babich, and Panos, 2015). There is a risk of stolen data and lost employee device. It is necessary that business owner should execute encryptions tactics to make sure that the device is safe and secured against threats. As per my guidance the business owner can execute the capabilities of remote wiping so that IT managers can wipe the device instantly without taking the permission of the users. It would be great helpful for the business in the case of losing device of an employee. Business should make ensure that the data is not only protected but also be conventional to the IT infrastructure. The prior thing owner need to do is bring the full audit of the entire environment of IT in terms to decide whether the infrastructure of the company is set up to cope with workforce mobility or not. The visibility in the network layer should b necessary that is why the capabilities should be reviewed in a better position. These all factors can be accepted by the owner of the company which is able to protect the data of the company and informed to the owner about the activities of the CSR in all over the world. The mobility and BYOD issues can be resolved by applying the suggestion which is given by me. Although BYOD comprises various security risks, if handled in an appropriate manner, a program of BYOD can decrease the cost and enhance the productivity without hampering security. An owner should educate his employee on how to protect their devices from hazardous situat ions. Recommendations to owner for expanding the staff The business has increased globally so owner should hire staff for separate department. It has been studied by case study that there are small numbers of staff have access to all the applications that are utilized including the accounting systems. It defines that business has small number of staff with the responsibility of handling various department. It has been recommended by me to the owner of the company to expand the range of staff so that staff can be divided into the department and the requirement of each department could be accomplished. Staff should be increased as per the requirement of the departments and Bentley food services should distinguish department in the form of IT department, accountant department, human resource department and administration. It would be helpful for the business to protect their business product in better way with specific information. The owner should do not required to accomplish it in wider way but different department would be helpful for d istinguish the services. It will also reduce the burden of the owner and help to provide more safety. Internal controls should be considered by the owner because it facilitates to prevent their assets and reduce the risk of fraud. There are some certain steps which should be implemented by the owner of the company which would be helpful to reduce the risk of fraud and maintain the culture that produces accurate and timely financial information. It is important for the owner of the business to set up the written policy that clearly defines the policy for integrity and ethics. Business owner should consider assessing and possibly revising their policies on annual basis for making changes in the working environment. As now businesss employees are working different places so video conferencing should be handled or done between the business owner and employees. Financial document regarding the business should be managed in an efficient manner and the business owner need to understand that in generating the document related to financial when attesting a tax return, there is frequent an explicit financial statement are required in accurate position. It can be done only due to availability of the accountant department who should have the access to make the financial report of the company by analyzing the various taxes. It has been recommended to the business owner to take proper time to ensure that they are ready with the reporting. Administration department would be helpful to manage the data of the company and can inform prior (Lacity and Peter, 2014). As it is mentioned in the case study that Stock is held in warehousing facilities in each state and products shipped on demand. The owner should give the responsibility to the administration department to handle the information about the stocks which is held in warehouse and inform prior if an ything is required. For making the good arrangement in the context of IT, owner need to hire the It team for managing the various stocks and data of the store at one place by using cloud computing software. The access should be given by the owner of the business to the staff as per the department so that the staff of the business could not get confused and provide relevant information in the time of requirement. It is the model which is helpful to determine the strategy for improving the strategy within the business. it is required for the organization to identify the issue initially after that it is required to analyze. Plan should be developed with an adequate manner after that implement it in the company. Plan should be critically evaluated. Apart from that there is various responsibility of the payroll so it has been recommended to the owner to create the payroll team. It is considered as the biggest expense of the business that is why the owner should pay attention towards it. There are various frauds can be done such as unapproved overtime, unapproved pay raises etc. timesheets should be created and managed in proper manner before paying payroll. The work of payroll is not done with paying the salary to the staff but the staffs of payroll are mingled with other responsibilities such as payment controls (French, Chengqi and Jung,2015). It is necessary for the owner of the business to fo cus on payroll department as well because it will be helpful to reduce the burden of him but the owner of the company should take up to date information regarding every department. If owner manage each department with efficiency, it will bring huge profit in the context of business because everyone in the staff of the business would be responsible for their own work and have access of their department. It will bring thee sequence in the business in which the owner of thee business can easily checkout the various information and provide the real time data to customer service representatives. Management of IT services, cloud or outsourcing Technology is the backbone of every business and manged services are able to move on right strategy. It is important for the owner of ten businesses to manage the IT services and outsourcing in an efficient manner. I would like to recommend them to choose the right provider for the needs of the business. Services should be managed to gain the advantages from outsourcing IT that is control IT success, reduce labor costs, enhance the efficiency and competitiveness, reduce risk and quickly implement new technology. The IT of the business can be outsourced data backup, recovery and storage and data centre functions such as data processing and storage. There is various kind of IT outsourcing which able to offer the number of options when contemplating outsourcing to IT functions. Cloud computing has established a revolution of technology for small business which is able to providing access to a range of capabilities that only for available for the larger companies (Rittinghouse and James, 2016). Owner should manage thee IT cloud computing services as he required and pay for what he use on a basis of monthly such as utility services. Cloud based programs can be used by company at any time on any device with the use of internet connection. It provides the benefit that brings a huge collaboration. A business owner should allow them to do work from anywhere because customer service representatives travel various places to explore the market for bringing the knowledge about the latest trend and the demand of the customer. I would like to recommend that the use of cloud based software brings the collaboration in teams without requiring attachment of e-mail and share the list of tasks from wherever they are. The customer service representatives who are presented in different locations can connect through instant messaging and even appear in the spontaneous meetings with robust audio and web conferencing. Along with that the owner of the business can attend the meetings with various clients and vendors from different location with the help of cloud based services. He can use cloud service for reducing the cost which will be helpful to save money. The natures of cloud resources are elastic or flexible so it would be possible for the owner to enhance capacity to support growth. For instance, if customer of the company need of enhancing collaboration, owner of the company can access collaboration tools hastily without making any plan. The flexibility of the Bentley services enhance when the owner works in the cloud. The business owner should hire the IT team for managing the cloud based software as it is mentioned in the case study that customer service representatives are required data in real time. He needs to hire IT team for handling the software and IT services because it is not possible that he can manage everything on his behalf. They should be managed by providing the entire information about the requirement of the business and the customer service representatives. The owner is afraid about risk and losing data, the staff should have the sufficient knowledge about the handling software so that the fear of owner can be disappeared. They should be managed with various IT outsourcing because it would be helpful for the business to reduce labor costs. Hiring and training a staff cannot be affordable for the small business because it helps to bring the required human resources. IT staff can be able to use the IT outsourcing when Customer service representatives want the data. Pricing models f or IT service outsourcing is different for every country but business owner should make his mind to pay $100 to$150 per month per user. Service operations of the business The service operations are essential process for the company because it has the objective to make ensure that all information and requirements are monitored continuously (Zurich, 2017). It helps to distinguish various events in term to determine on corrective actions. It is the responsibility of the management to restore the services to the earlier stage as soon as possible. I would like to suggest to the owner to focus on food operations and provide efficient services to the customer so that the demand of Australian produce local food can be increased. A food service operation involves a food delivery sales operation, temporary food service operation and vending machine location. It is important for the management of the business and the various department s about the taste and the demand of the customers. As mentioned in the case study that customer representatives were initially employed on a contract basis. It has been recommended by me to the owner to keep focus on various repre sentatives by taking support of IT team and keep in touch with them on continuous manner. I would suggest to owner in the regard of service operations that there are many processes which are the part of the service operation and the owner should consider them appropriately. The owner should make sure that the delivered services as per customer demand are monitored on regular basis. The events are categorized as per the decision making. There should be proper application management so that the various essential applications can be managed throughout their life cycle (Asatiani, Uday, Esko, Mikko and Timo Saarinen, 2015). The current concern of owner regarding the services and the products of the business is correct. He is more concerned about the safety, BYOD issues, mobility and the process of business structure. The owner should focus on corrective form of business process so that all services and requirements can be done in a sequence manner. The service operation of the business should be established appropriately. Service operation contains the effective relationship between employee and the employer. The Bentley food services need to enhance the operational efficiency, capturing new markets and outsourcing. The effective service operations are able to reduce the cost of the operations. I want to advice to the owner of the business to focus on the activities needed to operate the services and eligible to maintain their function ability as per the service legal agreements. The owner should fulfill the request of the services for managing the lifecycle. Owner should provide the right to the user to get access in the data where he can find out the information regarding data and to be able to use a service or group of services. It services should be restore into normal operators as soon as possible for the purpose of reducing the adverse influence on the business operations (Radnor and Nicola, 2016). Problem management is t he element of the service operations which is able to reduce the impact of incidents and issues on the business which can be caused by errors in IT infrastructure. It is the management which can protect the reoccurrence of incidents regarding to the errors. The business value of service operations in the business is higher because it has various features such as reduced unplanned labor costs, quick and effective access to standard services. As per my point of view, the owner of the business should focus o the improvement of the service operations and make the security policy goals and objectives that can be achieved by the employee of the business easily (Lee, 2016). The relationship between IT and administration should be effective and cooperative so that in the time of requirement of specific information about the data and the stock availability. Technical management and operational management both play a crucial role in the maintenance of the IT infrastructure. Bentley Beverage s ervice provides the foods and beverages across Australia s a wholesaler and not the business has spreader so it is required for the owner of the business to increase the products of food as well. Customer representatives need to deal with producers as well as sales queries of the customer and vendor. Conclusion It has been concluded that Bentley Beverage Services can improve their business process and management by adapting the operational and tactical management. It is report which has been made on the concern of the owner about mobility, BYOD issues, poor process and IT arrangements. Business process is a collection of activities which is necessary for the organization to attain the determined goal in certain period. As a consultant I advised to the owner of the business to keep concerned about the process and the management of the business because these are the most important element of every business. BYOD is referred as the Bring Your Own Device which is eligible to provide the greater flexibility. However, it can become the major issue of the business when employee of the company is allowed to use its personal device for accomplishing the task of the company. It is required for the company to put in place the appropriate policies and procedure to handle these issues. Service operation s are the key tool for improving the process and it has been recommend by me to enable service operation and its management in an effective manner.
