Thalassemia Essay Example
Thalassemia Paper Beta Thalassemia Beta thalassemia is an inherited blood disorder characterized by the abnormal production of a blood protein called hemoglobin. This condition is caused by a mutation within the gene that is responsible for the healthy production of hemoglobin. In healthy people, hemoglobin carries oxygen to tissues and cells throughout the body. Patients with beta thalassemia do not have adequate levels of oxygen within the blood, which can cause anemia. There are two main types of beta thalassemia with symptoms that range from mild to severe. Beta-globin is produced by two genes, one gene from each parent. The severity of the condition correlates with the amount of normal beta-globin production. Beta Thalassemia Minor The individuals with thalassemia minor have only one copy of the beta thalassemia gene. These individuals are said to be heterozygous for beta thalassemia and will have mild anemia. This situation can vary closely resemble that with mild iron-deficiency anemia. However, people with thalassemia minor have a normal blood iron level. No treatment is necessary for thalassemia minor. In particular, iron is neither necessary nor advised. Beta Thalassemia Major The child born with thalassemia major has two genes for beta thalassemia and no normal beta chain gene. The child is homozygous for beta thalassemia. This causes a striking deficiency in beta chain production and in the production of HBA. The clinical picture associated with thalassemia major was first described in 1925 by the American pediatrician Thomas Cooley. Hense, the name Cooleys anemia in his honor. At birth the baby with thalassemia major seems entirely normal. Anemia begins to develop within the first months after birth. It becomes progressively more and more severe.

More precisely, The HBB gene is located from base pair 5,203,271 to base pair 5,204,876 on chromosome 11. Characteristics of the Disease Beta thalassema major is characterized by severe anemia that can begin months after birth. In the United States and other developed countries, beta thalassemia is identified and treated early and effectively. In untreated, beta thalassemia major can lead to severe tiredness, jaundice, and growth and developmental delay. The body attempts to compensate by producing more blood cells in the bone marrow. However, this is ineffective without the needed genetic instructions to make enough functioning hemoglobin. Instead, obvious bone expansion and changes occur that cause characteristics facial and other changes in appearance, as well as increased risk of fractures. Severe anemia affects other organs in the body such as the heart, spleen, and liver. This can lead to heart failure and enlargement of the the liver and spleen. When untreated, beta thalassemia major generally results in childhood death, usually due to heart failure. Fortunately, in developed countries diagnosis is usually made early, often before symptoms have begun. This allows for treatment with blood transfusion therapy, which can prevent most of the complications of the severe anemia caused by beta thalassemia major. A compelet blood count will identify low levels of hemoglobin and other red blood cell abnormalities that are characterized with beta thalassemia. Since thalassemia trait can sometimes be difficult to distinguish from iron deficiency, tests to evaluate iron levels are important. A hemoglobin electrophoresis is a test that can help identify the types and quantities of hemoglobin made by an individual. This test uses an electric field applied across a slab of gel-like material. Hemoglobins migrate through this gel at various rates and to specific locations, depending on their size, shape, and electrical charge. In addition, isoelectric focusing and high-performance liquid chromatography (HPLC) use similar principles to separate hemoglobins and can be used instead of or in various combination with hemoglobin electrophoresis to determine the types and quantities of hemoglobin present. Hemoglobin electrophoresis results are usually within the normal range for all types of alpha thalassemia. However, hemoglobin A2 levels and sometimes hemoglobin F levels are elevated when beta thalassemia disease or trait is present. Hemoglobin electrophoresis can also detect structurally abnormal hemoglobins that may be co-inherited with a thalassemia trait to cause thalassemia disease or other types of hemoglobin disease. Sometimes DNA testing is needed in addition to the screening tests. This can be performed to help confirm that diagnosis and establish the exact genetic type of thalassemia. Treatment or Management of the Condition The most common treatment of all major forms of thalassemia is red blood cell transfusions. These transfusions are necessary to provide the patient with a temporary supply of healthy red blood cells with normal hemoglobin capable of carrying the oxygen that the pateints body needs. While thalassemia patients were given infrequent transfusions in the past, clinical research led to a more frequent program of regular blood cell transfusions that greatly improved the patients quality of life. Today, most patients with a major form of thalassemia receive red blood cell transfusions every two to three weeks, amounting to as much as 52 pints of blood a year. Because there is no natural way to the body to eliminate iron, the iron in the transfused blood cells builds up in a condition known as iron overload and becomes toxic to tissues and organs, particularly the liver and heart. To help remove excess iron, patients undergo iron chelation therapy, in which a drug introduced into the body which binds with excess iron and removes it through the urine or stool. In 2005, FDA approved an oral chelator, Exjade. This is a pill which is dissolved in water or juice once a day. Molecular Genetics Beta thalassemia is caused by mutations in the HBB gene. More than 250 mutations in the HBB gene have been caused beta thalssemia. Most of the mutations involve a change in single DNA building block within or near the HBB gene. Other mutations insert or delete a small number of nucleotides in the HBB gene. HBB gene mutations that decrease beta-globin production result in a type of the condition called beta-plus thalssemia. Mutations that prevent cells from producing any beta-globin result in beta-zero thalssemia. Without proper amounts of beta-globin, sufficient hemoglobin cannot be formed. A lack of hemoglobin disrupts the normal development of red blood cells. A shortage of mature red blood cells prevents these cells from carrying and delivering enough oxygen to satisfy the bodyââ¬â¢s energy needs. A lack of oxygen in the bodyââ¬â¢s tissues can lead to poor growth, organ damage, and other health problems associated with beta thalassemia. Genetic Testing DNA analysis is available to investigate deletions and mutations in the beta-globin producing genes. Family studies can be done to evaluate carrier status and the types of mutations present in family members. DNA testing is not routinely done but can be used to help diagnosis thalassemia and to determine carrier status. Other relevant information Being a carrier of the disease may confer a degree of protection against malaria, as it is quite common among people of Italian and Greek origin, and also in some African and Indian regions. This probably by making the red blood cells more susceptible to the less lethal species Plasmodium vivax simultaneously making the hosts red blood cell environment unsuitable for the more lethal strain Plasmodium falciparum. This is believed to be a selective advantage for patients with the various thalassemia traits.

Vegetarianism vs Omnivore Essay
Vegetarianism vs Omnivore Essay Vegetarianism vs Omnivore Essay Why Vegetarianism is better for the Health than Omnivorism? Abstract Vegetarianism is the practice whereby a person does not consume animal foods, restricting him or herself to eating vegetable foods only. Such a person is referred to as a vegetarian. Vegetarian diets vary widely, ranging from exclusive non-consumption of animal products at all to consumption of animal products such eggs, dairy products, poultry and fish. Vegetarian diets involve plant based foods like legumes, grains, vegetables, nuts fruits and seeds. Vegetarians vary depending on whether or what kinds of animals are eaten. Strict vegetarians are called vegan and their diets exclude all forms of animal products like fowl, meat, eggs and dairy. On the other hand, a lacto-ovo- vegetarian consumes dairy products such as eggs besides plants products. Whereas Lacto vegetarians consume dairy products in addition to plant products, an ovo vegetarian consumes eggs only, as animal products (Nordqvist). Fruitarian vegetarians consume raw and dried fruit and vegetables only. Cooking is believed to harm the fruitsââ¬â¢ nutritional ingredients. Such vegetarians eat all types of fruits, both sweet and non sweet. There are also the semi-vegetarians who consume plant based foods combined with slight amounts of poultry and fish. On the other hand, the macrobiotic vegetariansââ¬â¢ diet consists of cereals, whole grains and cooked vegetables. Omnivorism vegetarians on their part belief in the exclusive consumption of animal and plant based foods. They consume both in moderation. There is a growing concern that the different types of vegetarians like lacto vegetarians are ethical omnivores. An omnivorous diet contains plants and animal foods, but omnivorous persons put more emphasis on meat than on other foods (Nordqvist). As vegetarianism has gained popularity in the 21st century, there are reasons as to this newly emergent dietetic trend. Some of these reasons include the following: 1. How did vegetarianism come about? 2. What are the health benefits of vegetarianism, as opposed to omnivorism? 3. What are the social values for being a vegetarian, as opposed to omnivorism? 4. What is the ethics behind vegetarianism? 5. What is the spirituality behind vegetarianism? 6. How do I become a vegetarian? 7. What might happen if plants cease to exist anymore? History of vegetarianism dates back many centuries from the Asian subcontinent. However, vegetarianism is not historically constrained to the East. As early as the 16 century, Greek philosophers like Pythagoras and others abstained from meat consumption based primarily on their belief in the transmigration of souls. The 18th century vegetarian advocates included Voltaire of France and Franklin Benjamin of America. Although there have always been a followers of vegetarianism, the rapid growth of the movement in the United States occurred principally since the 1970s. Currently, there are millions of vegetarianism, as well as magazines, journals and books published to help them in pursuit of vegetarianism. One key reason for vegetarianism is regards for health. There have been nauseous concerns about sanitation of slaughter methods and production houses. This raises a health concern on possible contamination of the meat itself during the transportation, storage and entire preparation process. In America, there are about one million farmers and ranchers who carry out livestock farming. In comparison there are about six thousand plants that are federally inspected to process. Additionally, only four major packers process about 70 percent of beef and other four packers of 60 percent of pork in the United States. Further, there are concerns that persons concerned with slaughtering do not observe humane slaughter act of 1960. The act necessitates that, before slaughtering, animals must be rendered wholly unconscious, with the least of excitement and discomfort by use of electrical, mechanical and chemical (carbon dioxide gas) methods. Some persons contend that these methods are not as accur ately as they should be. Lack of observation of these principles results in contamination of the meat products considering that meat products are delicate and highly perishable products. In order to live healthy, persons should resort to vegetarianism (Keegan 136). Over consumption of meat products is the leading cause of weight gain, whereas overconsumption of vegetables does not result in weight gain. Meat intake results in calories add up bit by bit compared to fiber rich veggies like green beans. Persons who consume large quantities of meat are obese, while persons consuming veggies are healthier. Since meat consumption has resulted in obesity among many people, fast foods around the world are embarking on selling vegetable meals, which is increasing ground, implying that vegetarianism is better for health than omnivorism (CindyL). Omnivorism results in low life span as compared to vegetarianism conscious living. A survey sponsored by the United States national cancer institute revealed that persons who eat four bits or more daily are at 30percent risk of dying than vegetarians. The study further showed that processed meat also increases death risks. Meat does not contain fiber, which results in the digestive system complications. Further, lack of fiber in the body increases the risk of heart and cancer problems. According to National Cancer Institute, Rectal and colon cancer have resulted in more 51,690 deaths in United States in 2012. While lack of fiber in meats causes diseases, presence of fiber in vegetables protect the body against disease. As such, vegetarianism is better for health than omnivorism. Meats contain saturated fats which are harmful to the body. The meat fats surround the arteries and vessels of the heart, interfering with the proper functioning of the heart. The interference affects free movement of blood in the body, posing the risk of heart attack. Meats contain a high concentration of salts and nitrates. Meats like hot dogs and bacon contain high salts and other preservatives which are not healthy for the body. Further, such foods contain animal fur, which means that they are not prepared in healthy ways. Other preservatives in processed meats are harmful to the body, since they contain chemicals that are carcinogenic. For instance, high concentration of salts and nitrates can cause high blood pressure and trigger other cardiovascular and chronic ailments. In order to live healthy, meat consumption should be balanced with vegetables. Proteins obtainable from animal products can also be obtained in plants, whereas nutrients available in plants cannot be substitut ed for anything else. This is a clear indication that vegetarianism is better for health than omnivorism (CindyL). Vegetable foods are very healthy to the entire body, and especially the heart. Does the omnivorism affect the heart? This is a contentious topic that has been the subject matter of debate for several decades, but doctors and scientists came to agree that diets could cause or prevent heart disease. This view is also held by the seventh day Adventist religious group, who are massive flowers of vegetarian practices worldwide. The religious group holds the following precepts on the health benefits of a vegetarian lifestyle. They assert that Adventist omnivore men who are fifty five years and above are twice more likely to die of a heart ailment than vegetarian Adventists. Men aged 40 to 54 who eat meat more than six times a week are 4 times, likely to suffer from a deadly heart attack than vegetarian men. Women over 55 years who eat meat are 1.5 times at risk of a lethal heart attack than do female vegetarians. As for Christians who are strictly vegetarians, their assertion comes from th e book of psalms 104:14. The verse states ââ¬Å"He causes grass to grow for the cattle, and vegetables for the service of manâ⬠. Another verse in Genesis 1:29 that supports this view reads as ââ¬Å"I give you every seed bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for foodâ⬠(Contreras 85). Even the conventional American dietetic association recognizes that a budding body of scientific knowledge holds an affirmative association, between the consumption of a plant based diet and prevention of certain ailments. The meat industry denies the health gains of vegetarian diets. However, research on cancer high blood pressure, obesity and heart diseases indicates otherwise. A recent research on the role of diet in prevention of certain conditions evidences that heart disease is related to excessive intake of fats. The foods that we take are the sole important factor in establishing whether or not we develop heart diseases. Fruits and vegetables are the backbone of a healthy heart. Several studies show that persons who consume a lot of fruits have reduced risk of heart disease. One such example is Finland, where people consume potentially more fruit and vegetables. This change is related directly with decrease in deaths from the heart ailment (Keegan 156). In San Francisco, Dr. Ornish Dean of the California University found that individuals who consumed vegetarian foods that were low in fat had half the number of heart complications as people who ate meat on a typical American diet. Additionally, they shed off thirteen pounds and kept it off for a period of four years. Fruits and vegetables do not have cholesterol and are naturally low in fat concentration, calories and sodium. They are rich in fiber, folic acid, protein and vitamin C. In another study carried out in Italy, high levels of vegetable consumption led to 21 percent reduction in heart attacks and reduced chest pains by 11 percent. A high consumption of fruits also reduces blood pressure. Vegetables and fruits are rich is phytochemicals which help in prevention of heart ailment. Phytochemicals are biologically active minerals and vitamins that fall into plant sterols, flavanoids and plant sulfur compounds (Contreras 94). Plant sterols help to obstruct cholesterol assimilation from the diet or increase excretion of cholesterol in the body. Flavanoids extend the activity of vitamin C by acting as free fundamental scavengers, prevent LDL cholesterol oxidation, inhibit aggregation of platelets and possess anti-inflammatory action. Intake of flavanoids has been shown to decrease the casualty of heart ailment and the incidence of heart attack. Mature males with high consumption of flavanoids were 60 percent less the risk of heart death than low consumers according to the Zutphen elderly study. The study also revealed that most- menopausal women consumers of fruits and vegetables are responsible for 38 percent reduction in heart complications. Broccoli was found essentially noteworthy on reducing heart disease (Contreras 96). Plant sulfur compounds found in the allium family of vegetables has been shown to have preventive and protective properties against cardiovascular disease. Garlic leeks and onions are specifically shown to have these properties. Color pigments; anthocyamins in vegetables and fruits helps to shield consumers from heart disease. They protect heart disease by slowing cholesterol generation. Carotenoids pigments in yellow orange green and red vegetables are powerful anti oxidants that satiate free radicals, strengthen the immune system and protect the body against oxidative damage. Vegetables help to maintain the level of sugar in the blood which reduces the risk of adult onset diabetes (Contreras 91). By logically comparing omnivores and carnivores, it is clear that man was not created to take meat. Meat eaters have claws to help them in their meat eating habits while humans do not have claws. Meat eating animals have sharp front teeth for tearing flesh with no flat molar for grinding. Humans have no pointed front teeth, and have flat molars for grinding, similar to that of herbivores. Meat eaters have a larger intestine capacity that is thrice their body length in order to aid rapidly decaying flesh to bypass through rapidly. Human on the other hand have an intestinal track that is ten times their body size. Another physiological difference that shows that vegetarianism is better for a manââ¬â¢s health is that, meat eaters have a powerful hydrochloric acid in the stomach to aid meat digestion while humans have a weaker stomach acid. This shows that humans overwork their digestive system by consuming meat. Humans have a properly developed salivary gland, which is vital for pre- digesting grains and vegetables. Meat eaters do not have salivary glands in the mouth. These distinctions clearly show why vegetarianism is the healthy way for human beings (The Vegetarian Resource Group). A certain group of researchers investigated for the symbolic meaning of eating by contrasting the beliefs and values of omnivores and vegetarians. They contrasted a wide assortment of omnivores and vegetarians on the right wing totalitarianism, social domination orientation, eating values and human values. The participants tending towards omnivorism differed from those inclining towards veganism in two chief ways. The omnivores were more likely to sanction hierarchical ascendancy, and they placed less importance on sentimental states. Consequently, the approval or rejection of meat covaried with the approval or denunciation of the values related with meat; that discovery suggests that persons eat meat and embrace its representation in manners unswerving with their self definitions (Keegan 169). The spirituality behind vegetarianism is traceable in old religions like the Jewish and Christianity. Jewish dietary laws follow the context of mosaic laws, and they prescribe a healthy living whether one is Buddhist, Chinese or Muslim. Religious reasons are the primary reasons as to why some people adopt vegetarianism. Some religions assert the belief of re-embodiment, a multilfe relationship between animals and humans, thus, eating flesh is forbidden. As such eating flesh is considered as a taboo in religion. Vegetarianism becomes the best solution for such persons as they observe their diets (Keegan 159). Environment ethicists and advocates assert that a diet devoid of meat relates to environmental concern. Persons concerned on the planet ability to produce sufficient quantities of food to sustain a burgeoning population think that lessening meat consumption will aid. For illustration of this point, an acre of land will yield a greater quantity of edible plant than animal meat. One acre of land is capable of producing as much as 385 pounds of alfalfa seed from one pound of seed. If in turn the 384 pounds are sprouted for food, the yield will be around 3180 pounds of consumable sprouts. As such, consumption of plant can make a significant environmental difference. As part of ethics associated with omnivorism, taking the life of the poor animal is bad as it involves killing. In order to live a conscious life, a person can use the gradual or rapid change. Gradual change into vegetarianism is preferable because the slow change tends to become more of a lifestyle and long term move. Additionally, rapid change may not go well with some people; their digestive systems may not accommodate such so fast. A gradual change entails increasing intake of legumes, fruits, vegetables and whole grains while lessening meat intake at the same time. For persons who want to become vegetarians, they can follow the following guidelines. First, choose one whole grain products like cereals and rice. Ensure that the diet is diverse. Consider low or non fat dairy foodstuffs. Reduce intake of eggs consumed per week to three or four in one week. It is necessary to plan well on what foodstuffs to purchase when shopping. Read through the food labels before purchasing. Finally, it is essential to identify a specialist store where one will be obtaining supplies. If plants cease to exis t, there would be no life for both the omnivores and the vegetarians. Safeguard of plants should therefore be enhanced in order to drive healthy and conscious living. writing service provides students with quality custom written papers.

Does Violent Video Gaming Have an Effect on Children Research Paper
Does Violent Video Gaming Have an Effect on Children - Research Paper Example Kim et al (2010) have mentioned that ââ¬Å"excessive playing of video games may result in impaired academic performance (Kim et al, 2010). It is an accepted fact that most of the modern videogames are thought provoking and hence it can improve childrenââ¬â¢s skills such as numerical ability, problem solving, decision making, synthesis, analysis etc. At the same time, it should be noted that spending too much time for playing videogames may have detrimental effect on children as far as the academic achievements of the children are concerned. The increased influence of video games will force the children to decrease the time spent for learning academic topics. In other words, children who spent more time for playing videogames may spent little time for doing their home works, assignments or project works. Failure in doing home works may result in poor academic performances of the children in schools. Poor academic performances of the children may generate criticism from family and teachers which may generate frustration in the minds of children. Increased frustration may often come out in the form of violent behaviors. In other words, even nonviolent videogames can generate violent behavior indirectly among children. Children may discuss the themes of the violent videogames they played even at schools and they may try to implement it in their real life also. For example, Grand Theft Auto is one of the most popular videogames among children at present. The theme of this videogame is a motor vehicle theft as the name indicates. Same way Mortal Kombat is another videogame in which the major theme is fighting. Such videogames will definitely encourage children to do the same activities in their real life as they... Children of current generation are not much keen in playing physically hardworking sports and games; they are more interested in spending as much time in front of the computers, mobile phones or television sets for playing videogames. According to Gouzouasis et al (n. d), ââ¬Å"the type of extra-curricular activities like playing an instrument versus playing video games has differential effects on the personââ¬â¢s skill acquisition and personality developmentâ⬠. The themes of majority of the videogames currently available are violence. Many people believe that violent videogames play a vital role in the personality development of children. Moreover, many of the school violence incidents are happening as a result of the increasing influence of violent videogames upon children. Children who engaged in playing violent videogames may try to practice violence in their real life also. At the same time many other people believe that violence in videogames may not affect childrenâ⠬â¢s attitude or character very much. Videogames playing may have some utility as far as the mental development of the children are concerned. However, playing violent videogames may always affect the children negatively. Unknowingly children may develop violent behaviors as a result of continuous playing of violent videogames. Since children have less awareness in segregating good and evil, they may often try to practice the themes they observed in the violent videogames in their real life. Many of the school violence incidents are taking place as a result of the increasing influence of violent videogames upon children. In short, videogame playing, especially the violent videogame playing should be restricted among children. Parents and teachers should focus more on student activities and they should assist the children in the selection of videogames for playing.

Monetary policy Essay Example | Topics and Well Written Essays - 1250 words
Monetary policy - Essay Example The RBA often determines the official cash rate after deciding on what monetary policy target it intends to attain (Reserve Bank of Australia, 2012a). Such targets may include, increasing economic growth, lowering inflation. RBA uses open market operations to affect the changes of the official cash rate, which in turn trickles down to the financial system in the country. Although RBA changes the official cash rate through open market operations, the actual cash rates are often determined by supply and demand actions among banks. Each bank is free to determine the rate by which it lends to another bank. Changing the official cash rate however, impacts all other interest rates in the market which in turn impacts the supply and demand of money in the economic system (Reserve Bank of Australia, 2012b; Lowe, 1995:1-2). The market rate of interest on the other hand is the rate that financial institutions charge its clients for borrowing money. This interest is often impacted by changes in the official cash rate, whereby increases in cash rate would imply that the banks are borrowing from other banks expensively and hence would also increase the interest rate that they charge their customers for borrowing money. A drop in the official cash rate would make it cheaper for the banks to borrow funds and hence competition among banks would reduce the market interest rate across the Australian Economy (Smales, 2011:52-55). The RBA decreases the cash rate through open market operations in order to ensure that the official cash rate that has been set is as close as possible to the actual cash rate exhibited in the market due to forces of demand and supply. Each financial institution in the country has an Exchange settlement account for which enable banks to settle payments between each and also with the RBA. Where RBA wants to reduce the cash rate, it would buy repurchase agreements (repos) or second-hand common wealth government securities (CGS) from the financial institutio ns in the economy. The RBA pays the banks using their exchange settlement accounts with the RBA which increases the amount that they have access to and can lend out (Reserve Bank of Australia, 2012b; Kuttner and Mosser, 2002: 16). This increases the supply of money in the economy, and due to competition to lend out to borrowers, the cash rate as well as the market interest rates drop. This is as demonstrated in a simple Keynesian model below: As noted in the figure, when the RBA uses the open market mechanism to purchase government securities and repos, the money supply denoted by MS, moves from the original position MS to MS1 showing a rise in money supply. Since the supply money is inelastic relative to interest rates, the MS curve is perfectly inelastic. On the other hand, the demand for money changes with changes in interest rate. Hence as money supply increases in volume due to RBA purchasing repos and CGS, interest rates fall also drop. Answer two Effect of a decrease of inter est rate on: Consumption and Investment expenditures: a fall interest rates increases investment and consumption. As noted above, a fall in interest rates is as a result in an increase in money supply. This makes it possible for businesses and consumers increase their borrowing from banks at a lower rate of interest since it is cheaper to access loans. Hence, there would be an increase in consumption and investment expenditures financed by debt as businesses are able to access funds for capital goods such as equipments, and consumers are also able

It gives the fundamental steps of learning English which involves understanding the meaning of different vocabularies provided and using them in a well structured and grammatically correct sentence. As a teaching material, this WebQuest highlights the main objectives, which will serve as the yard stick of determining whether the intended purpose of the WebQuest is achieved. In addition to this, I give a positive feed back to the way the learning process is arranged. Understanding a word and pronouncing it correctly is indeed the fundamental step in solving the complexity in English as a language. This is because it creates a dovetail for the construction of grammatically and structurally perfect sentences to fit. Team work is undoubtedly important in building confidence among the students. It also enables them to share their difficulties and hence understand the challenges a head of them. Provision of resources is of importance because it gives the whole learning process the originality and reliability it deserves. The evolution process cannot go unaccredited because it will enable the lecturers to know if the objectives were met. However, the WebQuest fails to show what the students should do if they fail the second step of understanding the meaning of the words in the sentences. This in my opinion is crucial for the process of learning English as a second language.

Getting Things Done: The Art of Stress-Free Productivity :: Book Review, David Allen
The book I chose to read is Getting Things Done: The Art of Stress-Free Productivity by David Allen. David Allen is considered by Forbes Magazine to be in the top five executive coaches in the United States. He has over thirty years of experience in coaching some of the highest ranking executives in some of the biggest businesses in the United States. Time Magazine called this book, ââ¬Å"the defining self-help business book of itââ¬â¢s time." The book is broken down into three main parts and thirteen chapters and sub-sections. The first part is titled The Art of Getting Things Done. It contains information on societal shifts in the workplace and ways to manage work. Among his tips, he believes everyone should physically write down every task they must accomplish on a daily basis, whether they write it on paper or electronically. They must then make decisions based on length and importance and decide which tasks to accomplish and when to accomplish them. His main point of emphasis in this first chapter is that the mind becomes too cluttered and that short-term memory should be used to focus not store things. In chapter two, the author introduces his five keys or stages to controlling/managing workflow. They are (1) to collect, (2) process, (3) organize, (4) review and (5) do. He points to these five steps as a way to organizing work that needs to be accomplished and successfully completing it. The last chapter in the firs t section is about vertically focusing on the thought process to complete projects. Allen outlines five more steps to accomplish any task. They are (1) defining purpose and principles, (2) outcome visioning, (3) brainstorming, (4) organizing, and (5) Identifying next actions. The second part of this book, which is well over à ½ of the entire book, is somewhat of a repeat of the first part but a much more detailed perspective of the methodology of David Allen. He recommends taking two days at the start of his process just to get organized. Within these two days, one should set up private workspace not only at work but at home also. In chapter five and six, Allen refers back to his five keys to control workflow, he points out to accomplish the collecting phase completely before moving onto the processing and organizing stages. This will eliminate distractions. During the processing phase, a person is not really completing any items but rather identifying what needs to be done with each one.
