The Impact of Reforms within the Milk Sector in 1984 Research Paper

The Impact of Reforms within the Milk Sector in 1984 - Research Paper Example Milk is sold either through contract or cooperatives. The ratio of cooperatives in total milk production is different in the individual member countries of the EU because of differing systems of agriculture. The ratio of cooperatives is the lowest in Spain and Greece (18 and 20 percent), and is the highest, in Denmark, Ireland, Finland, Sweden and the United Kingdom (96-100 percent). Within the UK, milk and dairy products are mainly distributed through cooperatives. The milk production scenario in the UK is not just limited to distribution factors but also to its production which seem to determine the general outlook of the milk sector4. The milk sector in UK is a large one and there are around 12 million cattle in the UK mainly reared for beef or milk production. Department of Environment, Food and Rural Affairs or Defra is responsible for UK milk production and marketing policy. Defra has the responsibility for sponsorship of the dairy industry in the UK and helps to sustain the industry. The Common Agricultural Policy5 and milk quotas and UK policy on dairy are controlled and implemented by the Defra. Defra thus upholds global Milk and dairy policies and also represents UK interests at the EU Management Committee for Milk and Milk Products6. The pre-1984 scenario in the dairy sector showed higher production quantities and as there were no quota constraints, the more efficient producers could expand on a large scale whereas the least efficient ones had to leave milk production. Milk production quotas that were introduced by 1984 tend to thwart these market patterns and even allow the least efficient milk producing units to stay in business putting a check on the more efficient ones who have competitive advantages. There was an excess milk production in the pre-1984 scenario and the export facilities or even the disposal facilities were time consuming, expensive or even insufficient or unavailable7. What made the EU reform' The additional production quota, introduced in 1984, has been designed to reduce the imbalance between supply and demand for milk and milk products and consequently the resulting structural surpluses8. Thus with the quota system, excess production and surpluses could be handled more efficiently. Some of the factors responsible for introduction of quotas include budgetary pressures, over or excess supply of milk when productivity increased much more than the consumption and also external pressures. According to the Defra, the milk quotas system was introduced by the European Community in April 1984 in which member EU states were allocated a national quota of milk production and supply. This was done to curb excess production of dairy products and also to reduce expenditure on the disposal of surplus milk and milk products9. Pre-1984, expenditure on support and removal in the dairy sector had reached 5.2 billion euro that was 30% of the total agriculture budget10. Reform - The use of quotas/ super levies as the main instrument The quota limits were in place for EU milk production since 1984, and individual milk producers were subject to these policy changes.

Organisational Behaviour and Development-Assessment Task No 2 Essay

Organisational Behaviour and Development-Assessment Task No 2 - Essay Example These are the questions we will seek to address in this report and attempt to provide solutions based on various researches. Emotions in the workplace have a profound effect on everything we do as it affects thoughts and behaviors. On the other hand, attitudes are a representation of beliefs, feelings and behavioral intentions towards a person, object or event and involve conscious logical reasoning unlike emotions which occur as events often without awareness. Emotions affect workplace attitudes. In the workplace as we interact with co-workers, individuals experience a variety of emotions that shape our feelings towards the company, the job itself and our bosses. The most common of this attitude researched about in the work place are job satisfaction and organizational commitment (Workplace emotions and attitudes, n.d). From our case study, Fran’s Hayden suffered significant adverse effects at Dairy engineering arising substantially from job satisfaction and job role expectat ions. Job satisfaction represents an individual’s evaluation of their job and work content (Workplace, n.d). Frans expectations were affirmed from Peter Bruton her boss, Rob the chief accountant and herself. First we learn that Fran’s was interested in a position in the dairy engineering in the hope that she will gain practical experiences in addition to the higher salary. She was offered a position she knew she will not enjoy but still went ahead and accepted it. she was told her work will entail compiling the monthly report known as â€Å"big brother† but later she found her work was entirely clerical which made her wonder why MIS needed her yet she had very little to do in that department. Obviously Fran’s expectations of practical experience were not met. The other problems identified from the case study that made it unbearable for Fran is the poor organizational structure of dairy engineering. Every organization has components that require profession al and effective management. The key components of an organization are people and structure. Formal organizational structures are hierarchical with people at each level having their own objectives and people at the lower levels report to higher level managers. This system has the principle of unity of command inbuilt in it. This determines the efficiency of the organization which depends on the free flow of information, efficient communication system, well defined authority and responsibilities supported by detailed policies, rules and regulations. An organization must have outlined systems that are understood by everyone in the organization (Ashraf, n.d.). Looking at the Fran scenario in the dairy engineering, there was no formal on boarding process in place. On her first day of work, she was accompanied by a colleague who introduced her to the rest of the team then her boss explained to her what her duties are and she started working. A formal new hire process ensures that new emp loyees like Fran are given the same information with respect to company policies, expectations and procedures that ensures consistency and accuracy (Plowman, 2010). When Fran boss went on leave, Fran took orders from Rob the chief accountant who gave her the opportunity to attend a management workshop in Auckland. When Fran got back, her boss Burton was furious that he had not been consulted and he felt his authority was being undermined.Fran is not to blame since all she did was do as she was told. The

The Life Of Wolfgang Amadeus Mozart History Essay

The Life Of Wolfgang Amadeus Mozart History Essay One of historys most tragic figures, Wolfgang Amadeus Mozart begun his performing career as a child prodigy. He played the piano, harpsichord, organ, and violin beautifully and was taken by his father on a number of concert tours through several European countries. The young performer delighted his noble audiences, who rewarded him, however, with flattery and pretty girls rather than with fees. (Copied straight from the book and should be in quotes.) Mozart was fun loving, sociable, and generous to a fault, but he never learned the art of getting along with others. Fiercely independent, he insisted on managing his own affairs, apparently without great success: though recent scholarship reveals that he earned substantial sums, he was chronically short of money. (Quotation marks?)(Ferris, 2010) Mozart was born in Salzburg, Austria; Wolfgang Amadeus Mozart was a multi-instrumentalist who started playing in public at the age of six. Over the years, Mozart aligned himself with a variety of European venues and patrons, composing hundreds of works that included sonatas, symphonies, masses, concertos, and operas, marked by vivid emotion and sophisticated textures. (Quotation marks?) (Wolfgang Mozart. Biography) In the summer of 1781, it was rumored that Mozart was contemplating marriage to Fridolin Webers daughter, Constanze. Knowing his father would disapprove of the marriage and the interruption in his career, young Mozart quickly wrote his father denying any idea of the marriage. By December, he was asking for his fathers blessing. Wolfgang Amadeus Mozart married Constanze on August 4, 1782. Mozart and Constanze had six children, though only two survived infancy, Karl Thomas and Franz Xavier. (Copied from page 3 of website: Wolfgang Mozart. Biography) Karl Thomas Mozart (1784 1858), a skillful pianist, did not perform professionally. He became an Austrian government official and never married. With his death, the direct Mozart lineage ended. The youngest child, Franz Xavier Wolfgang Mozart (1791 1844), was known as Wolfgang Amadeus, Jr. Born only five months before his fathers death, he remembered nothing of him. In a classic case of a fathers fame intimidating a gifted child, the son showed early promise as a composer of depth and originality, but the image of the father he never knew loomed over his career with a stifling effect. (Copied from the indicated source.)(Famous family history) Mozarts father Leopold (1719 1787) was one of Europes leading musical teachers. His influential textbook Versuch Einer Grundlichen Violin Schule, was published in 1756, the year of Mozarts birth. He was deputy Kapellmeister to the court orchestra of the Archbishop of Salzburg, and a profile and successful composer of instrumental music. Leopold gave up composing of instrumental music. Leopold gave up composing when his sons outstanding musical talents became evident. They first came to light when Wolfgang was about three years old, and Leopold, proud of Wolfgangs achievements, gave him intensive musical training, including instruction in clavier, violin, and organ. Leopold was Wolfgangs only teacher in his earliest years. A note by Leopold in Nannerls music book, the Nannerl Notenbuch records that little Wolfgang had learned several small Andante and Allegro, written in 1761, when he was five years old. (Copied from Indicated source). (Wolfgang. Biography) Mozart firmly believed that supreme element of opera was music, which the text must always serve; never the other way around. He wrote serious as well as comic operas, and some of his works are a curious combination of styles. The Magic Flute, for example, is a German opera with both serious and comic implications, and Don Giovanni is a serious Italian opera that includes several comic episodes. The Marriage of Figaro is a delightful romp that nevertheless addresses serious political concerns of the emerging middle-class audience of late eighteenth-century Vienna. (Copied from Indicated source). (Ferris, 2010) Mozarts operas teem with love and anger, with humor, wit, pathos, and revenge. Yet Mozarts emotional expression is always under firm control for no matter how unlikely the plots or improbable the resolutions of his operas, he never abandoned classical restraint. Soaring melodies and attractive harmonies, presented in a wide range of orchestral and vocal timbres and effects, provide unfailing entertainment in these masterpieces of Music Theater. Although primarily a secular age, the Classical period was still strongly influenced by the church in some areas of Europe, and many eighteenth-century composers contributed to the repertoire of sacred-Catholic or Protestant-music. (Copied from Indicated source). (Ferris, 2010) Haydn and Mozart, both Catholics, continued the well-established tradition of writing Masses, oratorios, and other religious compositions for church and for concert performance. Haydn, profoundly moved by Handels Messiah, in his last years wrote two beautiful oratorios of his own, The Creation and the Seasons. Both Mozarts and Haydens Masses contain passages for solo voice and for small vocal ensembles, alternating with magnificent choruses all accompanied by organ and orchestra. The solo passages are sometimes quite operatic, but the emphasis in these religious works is on the choral sections. The irrepressible Haydn, criticized for writing religious is on the choral sections. The irrepressible Haydn, criticized for writing religious music that was too happy, replied that he did not believe the Lord minded cheerful music. (Copied from Indicated source). (Ferris, 2010) Mozarts years in Vienna, from age twenty-five to his death at thirty-five, cover one of the greatest developments in a short span in the history of music. In these ten years Mozarts music grew rapidly beyond the realm of many of his contemporaries; it exhibited both ideas and methods of elaboration that few could follow, and to many the late Mozart seemed a difficult composer. (Wolfgang. Biography) In the years 1763 1766, Mozart, along with his father Leopold, a composer and musician, and sister Nannerl, also a musically talented child, toured London, Paris and other parts of Europe, giving many successful concerts and performing before royalty. The Mozart family returned to Salzburg in November 1766. The following year young Wolfgang composed his first opera, Apollo ET Hyacinthus. Keyboard concertos and other major works were also coming from his pen now. (Mozart Biography) In 1769, Mozart was appointed Konzertmeister at the Salzburg Court by the Archbishop. Beginning that same year, the Mozart made three tours of Italy, where the young composer studied Italian opera and produced two successful efforts, Mitridate and Lucio Silla. In 1773, Mozart was back in Austria, where he spent most of the next few years composing. He wrote all his violin concertos between 1774 and 1777, as well as Masses, symphonies, and chamber works. Toward the end of the 1780s Wolfgang Amadeus Mozarts fortunes began to grow worse. He was performing less and his income shrank. Austria was a war and both the affluence of the nation and the ability of the aristocracy to support the arts had declined. By mid 1788, Mozart moved his family from Central Vienna to the suburb of Alsergrund, for what would seem to be a way reducing living costs. But in reality, his family expenses remained high and the new dwelling only provided more room. Mozart began to borrow money from friends, though he was almost always able to promptly repay when a commission or concert came his way. During this time he wrote his last three symphonies and the last of the three Da Ponte operas, cosi fan tutte, which premiered in 1790. During this time, Mozart ventured long distances from Vienna to Leipzig, Berlin, and Frankfurt, and other German cities hoping to revive his once great success and the familys financial situation, but he did neither. 1788 1789 was low point for Mozart, experiencing in his own words black thoughts and deep depression. Historians believe he may have had a cyclothymiacs personality with manic depressive tendencies, which might explain the periods of hysteria coupled with spells of hectic creativity. Between 1790 and 1791, now in his mid thirties, Wolfgang Amadeus Mozart went through a period of great music productivity and personal healing. Some of his most admired works. The opera, The Magic Flute, The final piano concerto in B-flat, the clarinet concerto in A minor, and the unfinished Requiem to name a few were written during the time. Mozart was beginning to revive much of his public notoriety with repeated performances of his works. His financial situation begun to improve as wealthy patrons in Hungary and Amsterdam pledged annuities in return for occasional compositions. From this turn of fortune, Mozart was able to pay off many of his debts. However, during this time both Wolfgang Amadeus Mozarts mental and physical health was deteriorating. In September, 1791, he was in Prague for the premier of the opera La clemeza di Ti to, which he was commissioned to produce for the coronation of Leopold II as King Bohemia. Mozart recovered briefly to conduct the Prague premier of The Magic Flute. Mozart fell deeper into illness in November and was confined to bed. Constanze and her sister Sophie came to his side to help nurse him back to health, but Mozart was mentally preoccupied with finishing Requiem, and their efforts were in vain. Wolfgang Amadeus Mozart died on December 5, 1791 at age 35. The cause of death was uncertain, due to the limits of postmortem diagnosis. Officially, the record lists the cause as severe miliary fever, referring to a skin rash that looks like millet seeds. It was reported that his funeral drew few mourners and he was buried in a common grave. Because he was buried in an unmarked grave, it has been popular assumed that Mozart was penniless and forgotten when he died. In fact, though he was no longer as fashionable in Vienna as before, he continued to have a well paid job at court and receive substantial commissions from more distant parts of Europe, Prague in particular. He earned about 10,000 florins per year equivalent to at least 42,000 US dollars in 2006. Wolfgang Amadeus Mozart death came at a young age, even for the time period. Yet his meteoric rise to fame and accomplishment at a very early age is reminiscent of more contemporary musical artists whose star had burned out way too soon. Constanze sold many of his unpublished manuscripts to undoubtedly pay off the familys large debts. She was able to obtain a pension from the Emperor and organize several profitable memorial concerts in Mozarts honor. From these efforts, Constanze was able to gain some financial security for herself and allowing her to send her children to private schools. At the time of his death, Mozart was considered one of the greatest composers of all time. His music presented a bold expression, of ten times complex and dissonant, and required high technical mastery from the musicians who performed it. His works remained secure and popular throughout the 19th century, as biographies were written and his music enjoyed constant performances and renditions by other musicians. His work influenced many composers that followed most notably Beethoven in its complexity and depth. Along with his friend Joseph Haydn, Mozart conceived and perfected the grand forms of symphony, opera, string ensemble, and concerto that marked the classical period. His seven year old son, Karl, noted that a few days before Mozart died his entire body became so swollen that the smallest movement was almost impossible. He also noted that there was an awful stench, which after death made an autopsy impossible. It was also observed that upon death the corpse did not become stiff and limbs were able to be bent, which is often the case when someone is poisoned. So was Mozart poisoned or was it disease that killed him? The poisoning theory is interesting in the Mozart himself started these rumors by telling his wife, I am only too conscious that my end will not be long in coming, for sure, someone has poisoned me! For a long time poisoning had been suspected. Who could have done it? The first suspect was his rival Antonio Sallieri, chief composer to the court of Emperor Joseph II. Mozarts wife blamed Salieri, and in his later years, suffering from dementia, Salieri, himself took credit for poisoning Mozart. This has been discredited as Salieri had no reason to murder Mozart. Salieri was in a position of power and esteem with a handsome stipend, and Mozart was of little threat to him. Some maintained that Mozart poisoned himself by treating his syphilis with mercury and using larger than recommended doses. Others felt the Freemasons did him in because his Magic Flute challenged their doctrines and revealed their secret rituals. An early 20th century German neuropsychiatrist, Mathilde Ludendorff, put forward one of the most bizarre theories that the Jews, Masons, and Catholics collaborated together to poison Mozart. Mozart was a studiously hard worker, and by his own admission his extensive knowledge and abilities developed out of many years close study of the European musical tradition. In particular, his operas display an uncanny psychological insight, unique to music at the time, and contuie to exert a particular fascination for musicians and music lovers today.

Interactive Media and Its Effects on Copywriting Essay -- Communicatio

Interactive Media and Its Effects on Copywriting Interactive media and the World Wide Web have become an entirely new medium for advertising copywriters. As new innovations in computer technology arise, copywriters find the best ways to utilize interactive media for marketing their products, and sometimes, themselves. They have discovered several key marketing methods including hypertext, JAVA, and accuracy of information. According to Duif Calvin, author of "The Nintendo Generation," hypertext is the most important marketing tool for advertising on the web. Hypertext is any type of link to another web site containing relevant information about a given topic. It has become very useful to marketers within the past few years. (www.jaderiver.com/glossary.htm). Hypertext allows markets to meet their audience's needs in very specific ways. For example, Ford Motor Company may have a site on the web devoted to the 1999 Ford Mustang. With the use of hyperlinks, Ford can provide detailed information about the car's warranty on a separate site. People who are interested in knowing m...

Application of the PRECEDE PROCEED Model to Fit Kids Fit Families FKFF Youth Physical Activity Campaign Essay

Obesity among American youths has become a national epidemic. Both developed and developing nations face a crisis of rising trends of obesity and overweight among adolescent youths (Centers for Disease Control and Prevention, 2004). Approximately 10 % of school children are overweight with US alone reporting 25 % of overweight children while 11 % of them are obese (Centers for Disease Control and Prevention, 2004). Preliminary data from the National Health and Nutrition Survey (NHANES), strong evidence of overeight and obesity is linked to increased mortality and morbidity in United States. Likewise, Houston Department of Health and Human Sciences reports that the prevalence of overweight and obesity among youths of ages 14-18 is 34.4 % compared to the Hispanic youths of 37 % and African American at 23.5 % of similar age group (Centers for Disease Control and Prevention, 2004). As such, the Fit Kids Fit Families has launched a national social marketing to provide awareness of physica l activity as a preventive measure of obesity and overweight. Fit Kids Fit Families group was founded in 2003, purposefully for promoting optimal weight and improving life quality among the African American people. The FKFF has selected activity as the target behaviour with the middle school youths as the target audience. The group mimics the PRECEDE-PROCEED model in several ways to provide physical activity intervention. As such, this paper describes the efforts of the group within the context of PRECEDE-PROCEED model as described by Green and Kreuter (2005). Phase 1: Quality of Life Diagnosis Youths suffer numerous consequences of obesity due to increased overweight and obesity. Polhamus, Dalenius, Thompson, Scanlon, Borland, Smith & Grummer- Strawn, (2003) writes that the excess body calories are converted into fats and finally stored in adipose tissue thus accumulates in the body of the youth. The individual is likely to develop a poor big body due to additional weight that adds more flesh. The children suffering from obesity are at risk of contacting multiple adverse health complications, some of which are fatal. Previous studies observe that high blood pressure while childhood is a weak predictor of premature death; however, high cholesterol had no relationship with early bereavement. Besides, health experts admit that factors causing obesity and high cholesterol were easier to control through exercise and medication. Researchers have identified children as the rapidly growing demographic in the global overweight population. For instance, approximately 31.9 percent of African American youths in have body indices that categorize them as overweight. Also, Polhamus et al. (2003) reports that 12 percent of obese people are likely to suffer from anxiety, impaired social interaction 17 %, and depression 34 %. Phase 2: Epidemiological Diagnosis The challenge of overweight and obesity epidemic is not limited to concerns about weight and bulk. According to Polhamus et al. (2003), 7 % of cases of obesity have resulted into disabilities through physiologic and psychological points of view. The increased waist to hip girth ratio is linked to increased risk of hyperlipidemia, cardiovascular disease, diabetes and hypertension. Likewise, obesity and overweight has been related to elevated risk of cancer, sleep apnea, musculoskeletal disorders, gallbladder disease, diverticulitis, and intracranial hypertension. Research shows that the prevalence of obesity among American youths has increased from 5 % to 12.4 % in this time period and the age group of 14 – 18 years it has increased from 6.4 % to 17 % (CDC, 2009). From the viewpoint of health, 20 % of youths have been reported to exhibit clinical obesity and overweight characteristics. Phase 3: Behavioural and Environmental Diagnosis In December 2014, NHANES provided FKFF with summary of current data to assist them narrow to the target behaviour and audience for social marketing intervention. Therefore, FKFF decided to prevent obesity among youths that were segmented into pre-school, middle school, elementary school, and high school. Since obesity has numerous environmental and behavioural determinants and because appropriate interventions may differ between the groups, it was significant to narrow the focus. Data presented by NHANES provides that 15.3 % of pre-school, 13.9 % of elementary school, 22.8% of middle school and 13.6% of high school youths are either slightly overweight or overweight. Also, 12.5 % of pre-school, 15.9 % of elementary school, 3.2 % of middle school and 10.5 % of high school youths are extremely overweight or overweight Polhamus et al. (2003) reports. Because the FKFF was aware that they would be using social marketing for obesity prevention, the information concerning developmental and cognitive characteristics of every age group assisted in narrowing to the high school as the target group.Further, FKFF chose physical activity as the target behaviour. The potential behavioural objectives were based on the objects set by health People 2010 related to physical activity. According to Health people 2010, national behavioural objectives of physical activity were to increase the youth proportion that participates in moderate physical activity for at least 30 minutes, 3-5 times a week. Secondly, it aimed to increase the proportion of youths engaging in vigorous physical activity that promotes cardiorespiratory fitness 4-5 times a week for 20 minutes per occasion. Lastly, Healthy People 2010 supports the increase in proportion of adolescent that participate in daily school physical education. The FKFF underwent formal environmental diagnosis in where the community researchers collected data to determine places youth say they participate in physical activity. Phase 4: Educational Diagnosis Green et al. (2005) described that enabling factors, predisposing factors, and reinforcing factors are the three major broad categories of factors influencing health behavior. The predisposing factors include motivation, desire for competition, parents and peers. Likewise, the barriers to physical activity included poor body image and desire not to mess up makeup hair. The influencing enabling factors included the availability of facilities and the opportunity to showcase talent while barriers of enabling factors were homework and V and computer games. Lastly, influencers of the reinforcing factors were active people on TV and peers while the barriers included self-concept and poor body image. Phase 5 & 6: Policy and Administration Diagnosis and Implementation The goal of intervention alignment is to try and fit the components of intervention program with various micro and macro-ecological levels of community. The key terms in this PRECEDE-PROCEED model are mapping. Matching, pooling, and patching where the ecological levels are matched to intervention components, where evidence is lacking, interventions that show promise are patched to fill the gaps, practice-based intervention programs are mapped to health problem determinants and evidence-based intervention are pooled and reviewed (Polhamus, Dalenius, Thompson, Scanlon, Borland, Smith & Grummer- Strawn, 2003). Therefore, the FKFF pooled and reviewed numerously existing physical intervention programs. The administrative assessment includes resource assessment needed to implement the program, incorporating timeline developmental and budget. FKFF personnel reviewed the steps of community –based prevention marketing and communicated time involved in the development of evidence-based intervention. Likewise, the committee prepared a one-year budget with consultation from the healthy people department. The appraisal of the organization implementing the program highlighted the commitment of FKFF consistency in obesity intervention program. The scorecard pilot program of FKFF is in the beginning stages of implementation. The members of the group continue to actively recruit members who will in turn provide incentives for youth to participate in physical activity through the reduced cost programs. www.fkff.com has been developed to provide information to the youth. Also, the local radio network has ben contacted for media coverage of the program. Finally, YMCA locations are set for free in the country to promote cool, fun opportunities for youths to be active. Recently, FKFF staffed fresh graduates from universities to provide a cool appearance and direct the youth fun and creative activities as well as providing ideas on creating fun without sports equipment. The programs for local events are underway with the recreation and parks department commencing the summer scorecard with youth beach run. Phases 7, 8, & 9—Process, Impact, and Outcome Evaluation The quantitative component of the evaluation seeks to provide answers for number of youths recruited, website hits, and youths registered, local events, and youths that participated in the grand finale. The group designed impact evaluation to determine if the behavioural objectives set are being met and will consist of the qualitative component. Impact evaluation addresses the level of a moderate increase in moderate and vigorous physical activity among the youths. Likewise, it will determine the level of physical education among the youths. This provides the achievements of health objective through quantitative measures. This provides answers for decrease or increase of risk for overweight among the youths. The baseline data obtained from the Healthy People 2010 will be used to conduct a follow-up on particular youths for the program.ConclusionThe PRECEDE-PROCEED model adopted by Fit Kids Families First in designing the obesity prevention intervention is beneficial for summarizing t he work done and insert what might have been done within the PRECEDE-PROCEED model framework. In particular, the explicit priority and objective setting was an essential proponent of the model. The model further assisted in determining the facets of the program evaluation.

Bariatric Surgery

Bariatric Surgery Indication: No studies evaluate the commonly used indications for bariatric surgery. Consensus guidelines suggest that the surgical treatment of obesity should be reserved for patients with a body-mass index (BMI) >40 kg/m(2) or with BMI >35 kg/m(2) and 1 or more significant co morbid conditions, when less invasive methods of weight loss have failed and the patient is at high risk for obesity-associated morbidity and mortality (strength of recommendation: C, based on consensus guidelines). Types:There are two basic types of weight loss surgery — restrictive surgeries and malabsorptive/restrictive surgeries. They help with weight loss in different ways. Restrictive surgeries:  work by physically restricting the size of the stomach and slowing down digestion. A normal stomach can hold about 3 pints of food. After surgery, the stomach may at first hold as little as an ounce, although later that could stretch to 2 or 3 ounces. The smaller the stomach, the less you can eat. The less you eat the more weight you lose. Malabsorptive/restrictive surgeries:  are more invasive surgeries that work by changing how you take in food.In addition to restricting the size of the stomach, these surgeries physically remove or bypass parts of your digestive tract, which makes it harder for your body to absorb calories. Purely malabsorptive surgeries — also called intestinal bypasses — are no longer done because of the side effects. Specific Types of Weight Loss Surgery There are many different surgical procedures for weight loss, and each has several variations. Adjustable Gastric Banding Gastric banding is among the least invasive weight loss treatments.This surgery uses an inflatable band to squeeze the stomach into two sections: a smaller upper pouch and a larger lower section. The two sections are still connected; it's just the channel between them is very small, which slows down the emptying of the upper pouch. Gastric banding physical ly restricts the amount of food you can take in at a meal. Most people can only eat a ? to 1 cup of food before feeling too full or sick. The food also needs to be soft or well-chewed. There are several brands of adjustable gastric bands available. They include LAP-BAND and REALIZE. Pros.The advantage to gastric banding is that it's simpler to do and safer than gastric bypass and other operations. It's routinely done as minimally invasive surgery, using small incisions, special instruments, and a tiny camera called a laparoscope. Recovery is usually faster. You can also have it reversed by surgically removing the band. Because the band is connected to an opening just beneath the skin in the abdomen, it can be easily loosened or tightened in the doctor's office. To tighten the band and further restrict the stomach size, more saline solution is injected into the band.To loosen it, the liquid is removed with a needle. The Cons. People who get gastric banding often have less dramatic we ight loss than those who get more invasive surgeries. They may also be more likely to regain some of the weight over the years. The Risks. The most common side effect of gastric banding is vomiting, a result of eating too much too quickly. Complications with the band aren't uncommon. It might slip out of place, or become too loose, or leak. Sometimes, further surgeries are necessary. As with any surgery, infection is always a risk. Although unlikely, some complications can be life-threatening.Sleeve Gastrectomy This is another form of restrictive weight loss surgery. In the operation, which is usually done with a laparoscope, about 75% of the stomach is removed. What remains of the stomach is a narrow tube or sleeve, which connects to the intestines. Sometimes, a sleeve gastrectomy is a first step in a sequence of weight loss surgeries. It can be followed up by gastric bypass or biliopancreatic diversion, if more weight loss is needed. However, in other cases, it might be the only s urgery you need. The Pros. For people who are very obese or sick, standard gastric bypass or biliopancreatic diversion may be too risky.A sleeve gastrectomy is a simpler operation that allows them a lower-risk way to lose weight. If needed, once they've lost weight and their health has improved — usually after 12 months to 18 months — they can go on to have a second surgery, such as gastric bypass. In people with high BMIs, sleeve gastrectomies result in an average weight loss of greater than 50% of excess weight. Because the intestines aren't affected, a sleeve gastrectomy doesn't affect the absorption of food, so nutritional deficiencies are not a problem. The Cons. Unlike gastric banding procedures, a sleeve gastrectomy is irreversible.Most importantly, since it's relatively new, the long-term benefits and risks are still being evaluated. The Risks. Typical surgical risks include infection, leaking of the sleeve, and blood clots. Gastric Bypass Surgery (Roux-en-Y Ga stric Bypass) Gastric bypass is the most common type of weight loss surgery. It combines both restrictive and malabsorptive approaches. It can be done as either a minimally invasive or open surgery. In the operation, the surgeon divides the stomach into two parts, sealing off the upper section from the lower. The surgeon then connects the upper stomach directly to the lower section of the small intestine.Essentially, the surgeon is creating a shortcut for the food, bypassing a section of the stomach and the small intestine. Skipping these parts of the digestive tract means that fewer calories get absorbed into the body. The Pros. Weight loss tends to be swift and dramatic. About 50% of it happens in the first six months. It may continue for up to two years after the operation. Because of the rapid weight loss, health conditions affected by obesity – such as diabetes, high blood pressure, high cholesterol, arthritis, sleep apnea, heartburn, and other conditions — often improve quickly.You'll probably also feel a dramatic improvement in your quality of life. Gastric bypass also has good long-term results; studies have found that many people keep most of the weight off for 10 years or longer. The Cons. By design, surgeries like this impair the body's ability to absorb food. While that can cause rapid weight loss, it also puts you at risk of serious nutritional deficiencies. The loss of calcium and iron could lead to osteoporosis and anemia. You'll have to be very careful with your diet — and take supplements — for the rest of your life.Another risk of gastric bypass is dumping syndrome, in which food is â€Å"dumped† from the stomach into the intestines too quickly, before it's been properly digested. About 85% of people who get a gastric bypass have some dumping. Symptoms include nausea, bloating, pain, sweating, weakness, and diarrhea. Dumping is often triggered by sugary or high-carbohydrate foods, and adjusting the diet help s. However, some experts actually see dumping syndrome as beneficial, in that it encourages people to avoid foods that could lead to weight gain. Unlike adjustable gastric banding, gastric bypass is generally considered irreversible.It has been reversed in rare cases. Therefore, getting this surgery means that you're permanently changing how your body digests food. The Risks. Because these weight loss surgeries are more complicated, the risks are higher. The risk of death from these procedures is low — about 1% — but they are more dangerous than gastric banding. Infection and blood clots are risks, as they are with most surgeries. Gastric bypass also increases the risk of hernias, which can develop later and may need further surgery to fix. Also, a side effect of rapid weight loss can be the formation of gallstones.Biliopancreatic Diversion This is essentially a more drastic version of a gastric bypass, in which part of the stomach — as much as 70% — is r emoved, and even more of the small intestine is bypassed. A somewhat less extreme version of this weight loss surgery is called biliopancreatic diversion with a duodenal switch or â€Å"the duodenal switch. † While still more involved than a gastric bypass, this procedure removes less of the stomach and bypasses less of the small intestine. It also reduces the risk of dumping syndrome, malnutrition, and ulcers, which are more common with a standard biliopancreatic diversion.The Pros. Biliopancreatic diversion can result in even greater and faster weight loss than a gastric bypass. Studies show an average long-term loss of 70% to 80% of excess weight. Although much of the stomach is removed, the remainder is still larger than the pouches formed during gastric bypass or banding procedures. So you may actually be able to eat larger meals with this surgery than with others. The Cons. Biliopancreatic diversion is less common than gastric bypass. One of the reasons is that the risk of nutritional deficiencies is much more serious.It also poses many of the same risks as gastric bypass, including dumping syndrome. However, the duodenal switch may lower some of these risks. The Risks. This is one of the most complicated and high-risk weight loss surgeries. According to National Institutes of Health, the risk of death from the duodenal switch ranges between 2. 5% and 5%. As with gastric bypass, this surgery poses a fairly high risk of hernia, which will need further surgery to correct. However, this risk is lower when the procedure is done laparoscopically.

The shrinking welfare state essays

The shrinking welfare state essays Welfare has been the topic of much controversy over the past few years. The welfare program has been important for many people. The purpose of welfare is to assist people who are jobless or cant make ends meet financially. One of the stated purposes of the Personal Responsibility Work Opportunity Reconciliation Act of 1996, popularly known as welfare reform was to end the dependence of needy parents on government benefits by promoting job preparedness, work, and marriage. To this end, this federal legislation, along with many other changes in state policies before and after passage, has increased incentives and requirements for families receiving benefits to move into work and eventually off welfare. After reading the article on the Shrinking Welfare State the question I asked myself was should there be a welfare reform? Personally I think welfare reform is more reasonable and feasible rather than abolishing welfare altogether. For one, the redistribution of wealth is necessary to maintain equality among the economic classes. The gap between the rich and the poor is widening each day, and welfare aids the redistribution of wealth. Secondly, doing away with welfare altogether would further impoverish those who are currently under it support. There is still a need for welfare, but amendments to its policies would reduce the cost of its upkeep as well as reduce welfare fraud. Such amendments to its policies can include a voluntary savings plan to reduce the amount of taxes paid or a limitation on the duration support. To do away with welfare altogether would increase the poverty level in the U.S. Though proponents of this movement site that many people take advantage of welfare, their argument is only half valid. No one denies, that welfare fraud exits, but doing away with welfare away altogether would hurt those residents who truly have a need for the support. Welfare reform can reduce fraud an...

Creative Writing on World Literature

Creative Writing on World Literature Introduction It is in the 1660 that is referred to as the date of restoration. This is the period in which the republican experiment that was under Cromwell came to an end. It then gave the British a chance to reinstate the monarchy. On the other hand, restoration in the 18th century poetry in its cultural contexts is a combination of British writings pointed towards about four cultural contexts (David 2007). Below is a list of elements I could list as being important: i. Literally warfare ii. City landscape iii. Empire iv. A gendered society v. Personal voice The above listed aspects form the base of humanity within any form of society. They are the ones that orient people into their different roles and how they should go about them. For instance, we can talk of gendered society, as being the unit within a society which assigns roles to people through their gender. There are some roles which are seen as being meant for male whereas others are seen as female tasks (David 2007). We can also talk of personal voice, which entails one’s power or expression freedom. Another element ; literal warfare, denotes the arguments that could arise within a society. They can range from pet warfare to intensive warfare and its level is determined by the amount of effort put forward to counter one’s emotions (David 2007). The sections have been oriented through wheeler, with his poem writings. The poems talked about the political, poetic, and social discourse to which the authors are directed. The poem has been set in a way that it can fit the undergraduates and the graduates (David 2007). It is said that the restoration came at a period when the European countries found out that religion which they had considered as a uniting factor within their community had no authority in acting as the comfortable means of sharing life (David 2007). They later considered the fact that they needed a person with an outstanding authoritative power to guide them through the community. From the above mentioned culture, there was hope for a reasonable social and political life. Excessive emotions which had early on lead to religious bloodshed were a thing of the past and people could now interact and associate freely (David 2007). A section of the new program, of the reforms within culture gave attention to the forms of language at different levels. Due to the need of language to be improved and modified, passionate rhetoric metaphors that seemed to distract communication were done away with (David 2007). It was realized that, public communication or address should use a simpler language, the language should be clear as well, and that it should be able to appeal to the sentiments of the learned section of the society. These appeals also encouraged as well as discouraging some of the literal efforts. It is worth noting that in this period, are of great criticism. It brings out a form of thinking whereby reasonableness has overdone passionate feelings. Moving with cultural shift is a new phenomenon there is an increase in number of middle class of people considered as being literate. These people own a healthy amount of leisure with a good amount of utilizing power. There also is a change in terms of manners between people and within the society. We have learned on how men and women treat and interact with each other. This has largely affected those people in the middle class. The growth of journals, magazines, and other readings is said to be concerned with the group of these people (David 2007). The emergence of a form of faith in England, we get to see in two appropriate directions. Some Christians though resisted the change and were sticking to their perceived ways of life, they believed humanity to be a form of identity among people. On the opposite side of these events, another different group of people viewed the power of transformation brought about by science as being of no reference to religion (David 2007). It is out of those views political dominance prevailed. There was a 3rd group, the group is outside what can be said to be the mainstream political process. This consisted of those people who are unwilling to do away with their traditionalism. It is said to consist of Baptists and Protestants amongst others. In our case, the significant point to take is that the desire for a new reasonableness, within the public domain is responsible for satire. As defined, satire is composition of word phrases. It used in ridiculing people, whereby the use of this feature when writing or in speech discourages some form of vice. Satire has been used to bring out the weaknesses in those people who want to embrace traditionalism so much that they can’t move on with the improvement of the living patterns (David 2007). It could not be seen as impossible, for the world with full of ego to be encouraged by satire. Many of the major poets around the world used satire as a writing style. In this case, satire has been used to defend public order. However, it can also be seen as being used to criticize those who could not embrace change among the community. Different ranges of tone can be taken in satire. This is because traditionally, satire is seen as betraying what can be called a moral vision. This is done purposefully to swap between positive and negative criticism. Satire on the other hand also, can be able to take different forms, this can be gentle or savage (David 2007). Despite the different forms taken by satire though, it still remains to serve the same purpose. The effectiveness of satire in achieving its goal is said to be the moral subject of the audience. Satire is seen as a mirror which lets people see their faces. Rather than taking satire negatively or emotionally, people should learn on how to learn from satire as it will make them better entities.

Changes And Urban Expansion In Greater Dhaka Environmental Sciences Essay

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 attending 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 proj ected 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 unpla nned 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 c oefficient 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 ( Yuan, Sa waya, 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 the m old 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, accurate an d 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 term Study country As 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 termurbannext 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 millimeter s 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 Article The 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 amounting 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 hapl ess 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 ( Alam 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 analysis Data acquisition and readying Landsat 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 ( Asaduz zaman, 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.

Position Within Article Image categorization A alteration of the Anderson Scheme Level I method was used to measure LULC old termchangesnext term in this survey ( Anderson, Hardy, Roach, A ; Witmer, 1976 ) . 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 Types Description Built-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 array Position Within Article All 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 screen c lasss. 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 appraisal By 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 t he outskirts of Dhaka.

Position Within Article Three 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 hold had a pronounced influence on the development of suburban countries. In response to increasing old termlandnext term m onetary 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 agricultural production in the 1960s, the country has been used by local and migratory people for residential intents sinc e 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 may 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 th e metropolis 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 over the 28-year survey period. Table 4.

Table 4 shows a sum-up of the major LULC transitions, viz. ‘from-to ‘ information, which occurred during the survey period. As indicated, the bulk of old termurban landnext term was acquired by change overing countries that were antecedently agricultural old termland, following term flora, H2O organic structures or low-lying countries, proposing the being of increased force per unit area on natural resources in Greater Dhaka to run into the increasing demand for old termurban land.next term Life-size image ( 247K ) – Opens new window Life-size image ( 247K ) Fig.A 3.A Major old termlandnext term use/conversions in Greater Dhaka ( a ) 1975-1992 ( B ) 1992-2003. Position Within Article The survey revealed that the old termurban expansionnext term in Dhaka has been comparatively rapid and has resulted in widespread environmental debasement. 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 dirt y 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, and al ong 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 analysis LULC 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 extracted 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 wer e 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.

Position Within Article Census informations indicate that the old termurbannext term population of Dhaka was merely 0.34 million in 1951, increasing to 2.6 million in 1974 with an one-year growing rate of 9.32 % during 1961-1974 ( Islam, 1999 ) . 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 increasing force per unit area on the limited resource-base, and significantly contributed to the old termexp ansion 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. Decisions This 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 extende d and varied environmental debasement in the survey country, and the exposure to implosion therapy and the growing of slums have been the chief negative results associated with the rapid old termurbannext term development. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Integrated usage of GIS, RS and socio-economic informations could therefore be efficaciously used to understand the spatial and temporal kineticss of LULC old termchanges.next term The reading and categorization of RS informations were utile for gauging the rate and spacial form of the old termurban expansionnext term in Greater Dhaka of Bangladesh. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms.

Hormonal Influences on Breast Tissue during the Normal Menstrual Cycle Assignment

Hormonal Influences on Breast Tissue during the Normal Menstrual Cycle - Assignment Example This paper illustrates that according to Suri, the hormonal imbalance in female patient affects MRI accuracy. Menstrual occurs during cycles of between twenty-three and thirty-five days. In the book, Suri, explains that after the first half of the menstrual cycle is the best time to perform a breast MRI in women who experience a normal menstrual cycle. It is very difficult to figure out the best time to perform an MRI on women with an irregular menstrual cycle. Studies have shown that it is essential for doctors to measure progesterone levels before performing a breast MRI in women with irregular menstrual cycles. This helps in improving accuracy hence reducing the possibility of repeat tests. An MRI uses magnetic and radio waves to create a three-dimension image of the breast. A gadolinium which is a contrast resolution is injected into the body during an MRI. It collects in areas which have cancer growth thus helping doctors to see cancer. When progesterone levels are high more blo od flows in the breast. When this is the case, the contrast solution collects through ought the entire breast. This makes distinguishing regular tissues and irregular tissues hard, hence a possibility of repetition. According to Michell, today measuring of progesterone level should be done before a breast MRI is done routinely especially for women who have irregular menstrual cycles. However menstrual cycle whether regular or irregular should be put into consideration before an MRI is done. Disappointingly, most radiologists do not assess progesterone level or even put the women’s menstrual cycle into consideration. This turns out to be very expensive due to the repeat test which cost a tone of money. If a woman is about to have a breast MRI scan, she should talk to her radiologist about timing the MRI with respect to their menstrual cycle. If possible, Michell suggests that women should avoid going for a breast MRI during the second half of their menstrual cycle. This is bec ause progesterone levels are high during this period hence affecting the accuracy of the MRI resulting to repeat tests which are very expensive.
