Nutrition Implications in Complex Disease Whole Grain Oat Cereal Lowers Serum Lipids Essay Example

Nutrition Implications in Complex Disease: Whole Grain Oat Cereal Lowers Serum Lipids Essay Coronary heart disease, CHD, has been predicted to persist as the major cause of high mortality rate for the coming decades. In line with this, the development of ischemic heart disease was attributed to the increasing level of low-density lipoprotein or LDL blood cholesterol. According to the National Cholesterol Education Program or NCNEP adult treatment panel, less than or equal to 5.17 millimole per liter (200 milligram per deciliter) is the ideal blood cholesterol level for individuals of age higher than 20 years while higher than 6.21 millimole per liter or 240 milligram per deciliter is risky. In connection to this, about twenty nine percent of adults older than 20 years in the United States have 6.21 millimoles per liter blood cholesterol. Meanwhile, researches have shown that consumption of dietary soluble fibers lowers blood cholesterol level as epidemiologic studies revealed that the CHD development can be alleviated by means of dietary fiber consumption. In fact, more tha n thirty researches that were submitted to the Food and Drug Administration of the United States by the Federation of American Societies for Experimental Biology Report validated the efficacy of soluble fiber consumption on blood cholesterol reduction. Clinical studies showed that soluble fibers from selected gums, psyllium, oat bran, pectin, and oats generally caused six percent to nineteen percent serum cholesterol reduction. Since the low cholesterol and low saturated fat diet has been employed in hypercholesterolemia medical therapy, this study aimed for the assessment of commercially available whole grain oat cereal, as employed with the step-one diet of the American Heart Association (AHA), in the reduction of blood cholesterol level. Methodology This study has enlisted fifty-seven participants from previous researches advocated by the Heart Disease Prevention Clinic. While forty-six of these participants have joined the intervention phase, only forty-three persevere and endured until the end. The participants have ages in between twenty-seven and sixty-eight years with 50th to 90th percentile range of cholesterol level based on age and gender adjustments. In the recruitment of participants, individuals with higher than 3.39 millimole per liter of triglycerides, a body weight thirty percent higher than ideal, has major surgery and myocardial infarction history, gastrointestinal illness, unstable angina or   heart failure was excluded form the enlistment. Also, those who were presently in taking up drugs for medication such as lipid-lowering agents, thiazides, antibiotics, estrogens, corticosteriods, and progesterones were excluded. In line with this, those who were taking ß-adregenic blockers needed to maintain the dosag e of such drug during the duration of the study for them to become eligible. Finally, twenty-one men and twenty-two women were successfully made into the phases of this study.

Throughout the intervention phases, the participants were required to maintain weight while consuming about ready-to-eat cereals twice daily within four weeks. In connection to this, all participants were mandated to abide with the AHA step-one diet design during the duration of the study. Meanwhile, physiological data such as weight, nutrient data, and lipid profiles of the participants were determined from zero to four-week baseline. Moreover, the nutrient data based on four-day food records were evaluated by the National Coordinating Center. In the intervention plan, pairing of participants was done based on gender and entry cholesterol data, whereas in each pair one was assigned to â€Å"Country Cornflakes† while the other has undergone the â€Å"Cheerios† diet. The former was the control cereal while the latter was the source of whole grain oat. Both of these cereal types were produced through cereal processing equipment and each were pre-packed into 42.5 grams upon distribution to the participant. This was done in order to hide the identity of the commercial cereals used in this study. In connection to this, the researchers also ensured which cereal type was assigned to whom and the participants’ adherence to the consumption design by personal interviews and visitation. Meanwhile, the participants’ clinical assessment, as approved by the Centers for Disease Control and Prevention, was done after twelve-hour and twenty-four fasts from food and alcoholic drinks respectively. In every visit, b lood pressure, lipid profile, pulse, and body weight were accurately measured. In relation to this, participants have undergone clinical screening such as urinalysis, blood count, electrocardiogram, and physical examination. The lipid content of the blood collected through sodium-potassium ethylenediamine tetraacetic was analyzed in the University of Minnesota’s laboratory for Lipid Research Core. The high-density lipoprotein or HDL cholesterol, total cholesterol, and triglycerides were determined. Also, very-low density lipoprotein or VLDL and LDL were precipitated; Friedewald formula was utilized for LDL calculation. Lastly, the cholesterol data of the participants before undergoing the treatment was statistically compared with their respective cholesterol data analyzed after the intervention phases by means of t-tests and analyses of covariance. Results and Discussion The participants in this study were equally divided into two groups; the control group received cornflakes food supply while the treatment group was fed on whole grain oat. Both groups have 51.6 years as average age of the participants. Although the baseline body weight of the treatment group was five kilogram lower as compared with that of the control group, the difference did not make statistics significance. As such, there was no significant difference on the body mass index or BMI, and the baseline and post-intervention phase blood pressure among the two groups. Further, personal interviews on the participants revealed that their smoking and alcohol drinking habits as well as regular exercise in either group was maintained throughout the study. Luckily, complete blood count and blood chemistry of the participants did not change significantly during the study period. In terms of fat consumption, the total intake of the treatment group was decreased non-significantly from 56.7 grams to 51.8 grams. Moreover, the average diet changes were 11.2 milligrams per deciliter and +4.1 milligrams per deciliter for the treatment group and the control group respectively. Similarly, among the two groups, there was no significant difference on the key nutrients before and after the duration of intervention phases. Except for soluble fiber, there were no other significant changes with respect to diet composition among the two groups. Meanwhile, whole-grain oat group incurred 3.8% and 5.4% changes on total cholesterol and LDL cholesterol respectively. As compare with the control group, the treatment group had a decreased of 4.4% in total cholesterol and 4.9% LDL cholesterol. Although, there was no significant difference in HDL cholesterol between the two groups, they had a 0.20 millimole per liter LDL cholesterol difference. The exact mechanism of the cholesterol reduction was still unclear. It was theorized that the viscosity of soluble fibers lessen the rate of chime transfer in the upper gastrointestinal tract that causes low absorption rates, less blood nutrients, and changes in hormonal responses to delimited nutrients. In their hamsters study, Gallaher, Hassel, and Lee associated the reduction of plasma and liver cholesterol to the increase in the viscosity of the intestinal contents. However, viscosity was deemed only as a crucial requirement for the reduction of serum cholesterol. In this connection, it was proposed that soluble fibers hinder bile activity lessening the absorption rate. This process obstructs enterohepatic circulation leading to fast conversion rate of cholesterol to bile acids. In addition, other compound constituent of the fibers may also promote this process. For instance, tocotrienol in rice bran, oats, and barley inhibits cholesterol synthesis. Furthermore, the soluble fiber fermentation produces chain fatty acids which in turn hinder cholesterol biosynthesis. Changes in Serum Cholesterol and Sterol Metabolites after Intake of Products Enriched with an Oat Bran Concentrate within a Controlled Diet Introduction The United States Food and Drug Administration or FDA, in 1997, approved the notion concerning soluble fiber consumption and coronary heart disease or CHD risk reduction. The serum cholesterol or S-cholesterol reduction was ascribed to the soluble fiber, (1-3),(1-4) ÃŽ ²-D-glucan or simply ÃŽ ²-glucan present in oats and whole oat flour. Based on clinical claims, the consumption of three grams of ÃŽ ²-glucan per day results to S-cholesterol lowering and CHD risk reduction. Meanwhile, the S-cholesterol lowering mechanism was theorized to depend largely on increased bile acid activity due to viscous ÃŽ ²-glucan which in turn induces cholesterol and bile acid biosyntheses. The rate of cholesterol and bile acid biosyntheses can be traced on through the ratio of lathosterol to cholesterol and the presence of 7-ÃŽ ±-hydroxy-4-cholesten-3-one, respectively. Thus, this study aimed to assess the S-lowering of oat bran concentrate or OBC food products incorporated in the low-saturated fat and low-cholesterol diet of hypercholesterolaemic patients. Also, the OBC effect on bile acid and cholesterol biosyntheses were examined. Methodology The recruitment of the respondents for this study was done through newspaper advertisement. Twenty-seven individuals were examined but only sixteen has passed the screening and participated in the study. The participants should have ages of 35-70 years and 50-70 years for men and women respectively. In addition, all participants should have less than six millimoles per liter S-cholesterol level. On the other hand, individuals with less than four millimoles per liter S-triacylglycerol or TG, hyperlipedaemia, less than 30 kilogram per meter square body mass index or BMI, and with cases diabetes mellitus, liver disease, thyroid problems or kidney trouble and those under hormonal therapy or cholesterol medication were excluded. Hence, the final participants were composed of seven women and nine men with average age of 57 years, 25.4 kilogram per meter square BMI, and 7.47 millimoles per liter S-cholesterol level. This study was a single-blind and randomized cross-over that lasted for two by three weeks with 2.5 weeks washout period. As such, the experimental group was supplemented with OBC of about 2.7 grams per day ÃŽ ²-glucan in their diet while the control group was told to maintain their typical diet. In relation to this, laboratory test such as fasting blood sampling and body weight recording were performed. The results of every clinical test were only revealed to the participants after the completion of the study. The American Heart Association recommended diet was utilized as computations of every participant’s daily food requirements and menu planning were facilitated by MATS computer program. Strict compliance with the diet was imposed through regular checking as amounts of sweet foods and drinks were regulated. For instance, maximum of 375 grams of wine or 660 milliliter of beer were only allowed per week. Additionally, participants were given copies of the foods they ate for the first week and told to stick to such as much as possible. Fasting blood sampling was done every morning as the blood samples were analyzed in terms of low density lipoprotein or LDL cholesterol, TG, and high density lipoprotein of HDL cholesterol, and S-cholesterol. Further, serum lathosterol and 7-ÃŽ ±-hydroxy-4-cholesten-3-one levels were determined through gas chromatography. Meanwhile, statistical treatments were done by means of MS Excel and SYSTAT package. Pearson’s correlation and t-test were employed for correlational analysis and paired comparison respectively. Results and Discussion As compared with the control group, the experimental group has incurred six percent S-cholesterol reduction based on five-gram ÃŽ ²-glucan daily diet. In fact, a significant correlation S-cholesterol baseline level and total S-cholesterol changes during diet period were observed. In addition, changes on the serum metabolites which reflected bile acid secretion and cholesterol biosynthesis were noted. Moreover, the solubility of ÃŽ ²-glucan in OBC was calculated and found only as 50%. Weight losses which denoted S-cholesterol reduction also were observed. Meanwhile, due to the delimited fat intake, HDL-cholesterol reduction was noted as TG level was decreases in some participants only. Correlational changes on lathosterol and S-cholesterol implied cholesterol biosynthesis after oat diet. This observation was attributed to increase in bile acid production that was mediated by ÃŽ ²-glucan which in turn caused reduction in bile acid reabsorption. This process triggered bile acid synthesi s through cholesterol from plasma pool by means of LDL-receptor. Yet, no significant change on serum lathosterol and 7-ÃŽ ±-hydroxy-4-cholesten-3-one levels observed on participants. High-Fiber Oat Cereal Compared with Wheat Cereal Consumption Favorably Alters LDL-Cholesterol Subclass and Particle Numbers in Middle-Aged and Older Men Introduction High in fiber diet, in parallel with low-fat intake and other dietary factors, has been associated with the reduction of cardiovascular disease or CVD risk. Based on the meta-analyses of a number of studies, ÃŽ ²-glucan soluble fibers in oat products lessened serum cholesterol and low-density lipoprotein or LDL-cholesterol. It was inferred then that the capability of soluble fibers for CVD risk reduction is in concurrence with its capacity in modifying lipoproteins and serum lipids. In a number of cases, individuals with normal profile of serum lipids developed CVD. Thus, a closer examination on blood lipids attributes may provide insights on the possible CVD risk development and modify the efficacy of intervention for the prevention of such risk. However, no research has been conducted with respect to the effects of cereal and soluble fibers on lipoprotein subclasses, and particle size and number. Also, none has reported on lipoprotein and lipid changes brought either by carbohydrat e, and cereal or oat diet. Hence, this study aimed to determine cereal or oat diet on plasma lipid indexes such as LDL particle number, and lipoprotein subclasses and particle diameter. Methodology Men selected for this study were in between 25-35 years of age and have 50-75 kilogram per meter square body mass index. Individuals with CVD, diabetes, abnormal blood pressure, smoking habits, thyroid gland or eating disorders, and those who currently in any medication and with high amount consumption of fibers were excluded. At last, 36 men were successfully passed then clinical requirements that were divided into two groups. Then, weight and bodily measurements were gauged initially and periodically during the study. Nonetheless, the participants, under the instruction of dietitian, recorded their food preparations and sizes in four-day food intake. In connection to this, records of food intake were analyzed through Food Intake Analysis System or FIAS. Meanwhile, participants’ blood samples were taken before and after the twelve-week intervention. By means of nuclear magnetic resonance spectroscopy or NMR, the concentrations and particle size of blood lipids and lipoprotein s were assessed. Further, the insulin-augmented frequently sampled intravenous-glucose-tolerance test or IVGTT was applied to participants. For statistical treatments, Kolmogorov-Smirnov normality tests were employed prior to analysis of variance done through SPSS package. Also, analysis of covariance was performed for body weight changes and macronutrient intake. Nonetheless, t-tests were utilized to examine lipoprotein and lipid response differences. Results and Discussion Based on the results of this study, two large oat servings added to the regular diet of the participants, lowered small, dense LDL and LDL particle concentrations. In addition, in spite of the carbohydrate intake elevation and saturated-fat intake lowering, the concentration of triacylglycerol did not significantly increase for high-fiber oat group. In contrast, it was reported that triacylglcerol in blood increases along with the changes in lipoprotein and lipids in individuals who fed on wheat cereal with high carbohydrate intake and low-fat diet. Meanwhile, the association between triacylglycerol elevation and CVD risk development was linked on the changes in the composition of LDL and high-density lipoprotein or HDL cholesterol. In relation to this, the substitution of triacylglycerol by cholesterol esters in lipoproteins results to accumulation of triacylglycerols in HDL and LDL which in turn serve as reactant in hepatic triacylglycerol lipase. Then, the removal of triacylglycer ol leads to particle size decreased and density increased. Hence, in this study, the decrease in plasma tiaclyglycerol resulted to increase in LDL particle size for oat group but not with wheat cereal group. Analysis and Conclusion From the abovementioned studies, it was statistically proven that supplementation of oat cereals to the controlled diet of hypercholesterolemia patients caused blood lipids and HDL reductions. Further, oat meal diet results to LDL-particle size decreased and particle number increased which is beneficial in the part of hypercholesterolemia patients. On the other hand, it was theorized that the viscosity of soluble fibers lessen the rate of chime transfer in the upper gastrointestinal tract that causes low absorption rates, less blood nutrients, and changes in hormonal responses to delimited nutrients (Reynolds, Quiter, and Hunninghake, 2000). This process obstructs enterohepatic circulation leading to fast conversion rate of cholesterol to bile acids (Reynolds, Quiter, and Hunninghake, 2000). Thus, the increase in bile acid production as mediated by ÃŽ ²-glucan caused reduction in bile acid reabsorption (Davy, Davy, Ho, Beske, Davrath, and Melby, 2002). This process triggered bile aci d synthesis through cholesterol from plasma pool by means of LDL-receptor (Davy, Davy, Ho, Beske, Davrath, and Melby, 2002). As a consequence, the substitution of triacylglycerol by cholesterol esters in lipoproteins results to accumulation of triacylglycerols in HDL and LDL which in turn serve as reactant in hepatic triacylglycerol lipase. Then, the removal of triacylglycerol leads to particle size decreased and density increased (Davy, Davy, Ho, Beske, Davrath, and Melby, 2002). Nonetheless, other compound constituent of the fibers may also promote this process. For instance, tocotrienol in rice bran, oats, and barley inhibits cholesterol synthesis. Moreover, the soluble fiber fermentation produces chain fatty acids which in turn hinder cholesterol biosynthesis (Reynolds, Quiter, and Hunninghake, 2000). With these reasons, the research question â€Å"What is the effect of a diet high in dietary fiber and how does it decrease LDL cholesterol and serum lipids?† was plausibly answered.

Distributed Energy Production Essays

Distributed Energy Production Essays Distributed Energy Production Essay Distributed Energy Production Essay Distributed Energy Production Name: Course: Date: Distributed Energy Production Abstract This report reviews the costs associated with the use of green energy sources. In particular, it focuses on the use of solar and wind power. The report explains the methods used in the research as well as the results obtained after the research was concluded. From these results, several conclusions are made based on the viability of the sources of energy financially, economically and socially. The laws of the areas under investigation has also been included especially those that directly affect the use of both wind and solar powered energy. The opinions of the citizens relating to the installation of green energy in the area under study have also been raised. From this report, the viability of the green energy campaign has been evaluated and reported based on the area under study, which was in the state of Virginia. Distributed Energy Production 1. Introduction This report analyzes the importance of the utilization of green power. Green power refers to the use of renewable sources of energy as opposed to the non-renewable sources. Renewable sources include the likes of wind power and sunlight. They are essential in the conservation of the environment since they are renewable. This project was initiated to investigate the economic practicality and feasibility of the project in residential estates for example. Practicality will be considered by evaluation of the cost of the green energy. Feasibility on the other hand will address how dependable the use of green energy is in the residential area in question. The report identifies possible methods of how the use of green energy may be used in the area in question, Virginia. 2. Materials and Methods For this project, the materials required were an electric bill from the area under study and an estimate of the cost of the installation of the green energy in the area. This cost estimate obtained will be compared with that of green energy. The calculations done were non-biased in order to minimize the sources of error in the results obtained. Subsequent work took place in the laboratory since most of it involved calculations. These calculations had to be done correctly in order to endure that the results obtained were as accurate as possible to determine the economic viability of the project. They required the determination of the cost for 100% replacement of the energy use in the area under study. 3. Results a) Table representing the electrical usage of the residential site under study in Virginia MonthkWhOct 20111702Nov 20111830Dec 20112306Jan 20122482Feb 20122148Mar 20121740May 20121566Jun 20121699Jul 20121924Aug 20122711Sept 20122677Oct 20121983 b) The total cost for this period illustrated above was $191.64 c) Total cost of replacement of energy use by wind energy The approximate wind energy used was between 15-20 mph. The results will be based on the maximum and minimum values acquired after the calculation. I. Wind Turbine Power attained by the use of the 20 mph wind speed provided yearly= 15298 KWH Amount of power provided in percentage= 716 % Approximate amount of savings per annum=$ 2447.68 II. Wind Turbine Power attained by the use of the 15 mph wind speed provided yearly= 6454 KWH. Amount of power provided per annum= 302% Approximate savings made per year= $1032. 00 III. Total cost of the installation of the wind Turbine Power System in the area under study= $13, 750.00 c) Total cost of replacement using solar energy For solar energy, it was assumed that there was 3days storage to cater for the possibility of the occurrence of cloudy days. Panel battery calculations per household based on the 3800 watt daily usage= 10 solar panels. Cost of a single solar panel= $150.00 Total cost of installation of solar panels=$1500 Total savings obtained with this installation= $2500.00 Total cost of installation in a residential area of about ten families= $15, 000 Economic incentives that may affect the selection of either option include the reliability of the source of energy and the feasibility of the source of energy to the selected area. In the case of reliability, it will have a substantial effect on the economic situation of the area in question. If the source of energy is unreliable, the productivity of the businesses in the area will be affected as well. On the other hand, the feasibility of the installation of the source of energy refers to how appropriate the energy source is to the area in question. If the installation is not strenuous to the locality, it is feasible. Feasibility of the system is critical to the development of the town and the running of the area in question. The above economic incentives influence the selection process greatly. 4. Discussion From the results obtained, the use of green energy is economically viable since it is affordable even without the provision of government incentives. Conservation strategies like the use of appliances that consume less power may be used in order to decrease the amount of electricity in demand in both administrative and residential areas. In the state if Virginia, the installation of wind turbines is prohibited (Musgrove, 2010). In order to change this, the zoning policies will need to be reviewed to include the installation of the wind turbines. Some localities have decided to modify the laws in their areas of residence to allow the use of green energy. Such localities include Missouri and Texas (Douglas et al, 2009). The public considers wind energy beneficial in the conservation of the environment but the greater majority considers it unreliable. Installation of solar panels is allowed in the state of Virginia. Solar energy is assumed more feasible and reliable than wind energy by the residents of Virginia (Parks, 2010). An impediment to small-scale power generation is the cost that is associated with it. Power generation is very expensive since it requires the acquisition of new machinery that is costly. Distributed, on-site generation of solar or wind power will not be economically, legally and socially acceptable to the majority of the people in the area under study. This is mostly because of their reliability. These sources of energy are not reliable when compared to the power generated by fossil fuel. For this reason, the installation of these green sources of energy in the area in question will be faced with a lot of opposition especially from the business people in the area.

5 Situations When You DONT Need to Use the Services of Expert Writers

5 Situations When You DONT Need to Use the Services of Expert Writers 5 Situations When You DONT Need to Use the Services of Expert Writers Many students turn to the use of expert writers to seek help when they are busy or overwhelmed with writing assignments. And while expert writers are great to have on hand, especially for those more challenging situations, there are still times when hiring expert writers is not necessarily what you should do. Sometimes, you might be overwhelmed with your homework and you are just unable to complete all of your tasks. Often in these cases you might ask a custom writing service to provide you with a model paper so that you can use it as an example. But sometimes it becomes a habit, and it can become a bad one. It is for this reason that it is important to learn how to tell the difference between times when you need to order a model paper and times that you are merely falling victim to your laziness or procrastination. You do not need to services of expert writers when your paper is due within the span of several months. In cases like these you have plenty of time to conduct the necessary research, draft your outline, and write the paper. You need not bother with a model paper in such cases. You also do not need to rely upon the services of expert writers when your assignment is something designed to help you develop a new set of skills which you currently do not have. In cases like these you need to complete the task yourself as a matter of learning. You need to really push yourself in order to gain that knowledge, often because the knowledge or skillset you are gaining is something upon which you will expound for the next lesson. You really do not want to miss out on a key aspect of learning. When your professor sets extraordinary requirements it is important to avoid using a model paper. The reason for this is that a model paper might have different structure from the one required and if you do not follow the rules laid out by your professor it can end badly. Additionally, when an essay deals with the topic important for the whole subject you are writing your paper for, you should avoid working with a model paper because this means you need to plunge into it by yourself. When you know you can write it yourself but you are too lazy to do it, you should avoid hiring an expert. If you were to start writing the paper the moment you began making up excuses for why you don’t want to do it, you would be halfway done before you realized anything. Overall, there are times when the use of expert writers is ideal and a model paper can be used to help you write your paper. However, there are other times when you must avoid succumbing to the habit of using a model paper and instead overcome your laziness or procrastination so as to write a great paper.

Look into descripton - Essay Example Being a member of the minority, the non-Muslim group, had motivated me to use my skills and knowledge to help others cope with similar personal, environmental and social challenges. Now, as an adult I want to be of service for people who have difficulty expressing themselves when the opposition's voice is too loud, I want to devote my time helping those who can't help themselves. During university, I became a tutor and teacher's assistant for the opportunity to help students cope with the changes that entering university usually causes. My dedication to my job and in helping others was not unrecognized by my peers and superiors; as such I received several appreciation awards. In the future, I still see myself devoting more and more of my time educating people on how to help themselves. A Ph.D. from the JFK University will surely help me achieve this personal goal. As a Ph.D. student, I will be given the opportunity to explore and research human behavior extensively. This opportunity can help me hone my skills in dealing with people, specifically those underprivileged. The environment of my childhood and adolescence had instilled in me a strong passion for achievement. As a non-Muslim in Iran, I pushed myself to do better.

Islamic Finance Essay Example | Topics and Well Written Essays - 2000 words

Islamic Finance - Essay Example Agency cost is referred to internal cost of a company, which arises due to conflict of interest between the management and shareholders. The shareholders expect that the management should run the company in such a manner that it increases the shareholder’s value. However, it is observed that the management concentrates on maximizing the wealth of the company and does not take into consideration the interest of the shareholders. This creates a difference between the management and stakeholders. The same problem was observed in the Islamic banks; though the PLS system aimed at increasing the wealth of the investors but it failed to fulfil the expectation of the shareholders (Dar and Presley, 2000). The main rule of PLS system is that the banks provides part of its profit, obtained from investment, to the investor instead of interest. As a result, if the banks fail to earn any profit on the investments, the investors do not get any bonus (Dar and Presley, 2000). The same situation is observed when the company is small to afford high profit and even earn a considerable amount. If a new company invests in the bank, it has the right to earn the profit but the scheme had already dried up the earnings of the financial institutions. This indicates that the company as an investor is not at all profitable and the banks have failed to implement PLS appropriately. This has created misunderstanding between the management of the banks and the investors (small companies) as the payment under this scheme cannot be taken as granted (Abduh and Omah, 2012). When the banks failed to offer higher return on the scheme such as Murabaha financing despite good performance, it is subject to elements of uncertainty. These uncertainties are vague demand for goods and services, business environment that surrounds the world. Moreover, the banks are seen to suppress the profit as the

Development of Learning Objectives Through Reflection

Development of Learning Objectives Through Reflection The Williams report is based around educational best practice to enable young learners to acquire an understanding and appreciation of mathematics and its importance to their lives. The foremost concern, drawn from Ofsted and the Primary National Strategy findings is the need to strengthen teaching that challenges and enables children to use and apply mathematics more often, and more effectively (Williams: 2008 para.223) Reflecting on my practice will enable me to recognise my strengths, development needs and improve my practice to benefit all learners. Petty says: Effective teachers are always changing what they do; this is because they are continually learning how to teacher better. (2009: 520) Activating prior learning by constructing links, good planning and the conditions of the classroom can contribute to the effective opening of a lesson. Walker Tileston: Unless connections are made to their prior learning, comprehension and meaning may be dramatically lessened. (2004: 21). Therefore I ensured I revisited previous learning by looking at the way children approach word problems through reading the problem, highlighting the key words/numbers and choosing the appropriate operation before solving it. I then ensured they had chance to apply their skills to some word problems so I could assess their understanding and they could test their knowledge. When children gave correct answers during the mental/oral, I constantly praised them to build their self-esteem and confidence. Fontana says using praise and encouragement has a vital role to play in keeping children involved and interested in their work, and in helping them to build upon current achievements by raising their conf idence and their belief in their own abilities. (1985: 80) Giving children word problems to solve is an important aspect of mathematics because it is an opportunity for them to use their knowledge of operations/ mathematical vocabulary and apply it to real life problems. Bottle says: Giving children a real context for their problem solving gives them the best opportunity to become fluent in using mathematical skills and procedures. (2005: 33) After the mental/oral starter I ensured the learning objectives and success criteria were visible and shared with the children, so they could see what they were learning and what they had to do to be successful. I then asked questions on what methods the children used for addition and subtraction, which gave them a chance to actively participate and broaden their mathematical knowledge. The NNS says: Through a process of regular explanation and discussion of their own and other peoples methods they will begin to acquire a repertoire of mental calculation strategies. (1999: 7) I continued to ask questions throughout the lesson to enable me to assess childrens understanding, assessing common mistakes, analysing their methods and explore their language and vocabulary. Claxton says good learning starts with questions, not answers. (1990: 78) I ensured I was asking open ended questions in the main activity and plenary because I wanted to find out more about pupils understanding and to use their ideas to focus discussion about concepts. Kyriacou says that open and higher-order questions are more intellectually demanding and stimulating. (1995: 38) However during the mental/oral I tended to ask closed questions to keep the pace flowing. I tried to ensure I was giving the children thinking time after each question so they did not feel under pressure. Harries and Spooner say: Being asked to respond at speed is identified as a source of great anxiety. (2000: 36) This is why I decided to give the children number fans to show their answer, so they did not feel put on the spot. However I may have given them too long to answer as the rest of the class lost focus slightly. One strategy I could have used to avoid this was to ask a child a question, give them time to think about an answer, then ask other children in the class questions before returning to the pupil who had been given time for a response. This also would have enabled me to keep the pace flowing and help everyone reach their potential. I had to try and keep the pace of my whole class teaching at the correct level, as the class has a wide variety of learners with different abilities, therefore going too fast could cause the lower ability pupils to become lost and going too slow could mean the higher ability pupils are not being challenged. Wajnryb says: Students whose learning pace is faster than the pace of the lesson are prone to becoming bored, losing motivation and tuning out of the lesson. (1992: 118) When I introduced the new topic of adding or subtracting multiples of ten I could have given the children time to discuss the methods they might use in groups beforehand. This would have given them the confidence to participate more when I gave them questions to answer. Brown says: The opportunity for children to discuss ideas and express their own opinions is crucial. (1998, 43) Additionally during the questioning I only asked the children who had their hands up for the answers, rather than asking other children to see if they all understood. I could have provided more opportunities for student participation by getting them to write an answer and present it back to the class, which would encourage every child to use mental calculation. The NNS says An ability to calculate mentally lies at the heart of numeracy. (1999: 6) Giving the children mental calculations also contributes to the development of better problem-solving skills and gives them a sense of real life, as Thompson says: Most calculations in real life are done in the head rather than on paper. (2010: 163) The whole group teaching was beneficial as it enabled me to see the capabilities of all those in the class and adapt my practice accordingly. I organised the pupils on the carpet, to ensure everyone could see and so I could monitor behaviour, it also enabled me to notice changes in their posture and facial expressions, giving me clues about their understanding. Whole class teaching also meant I could interest the children in the subject they were covering rather than trying to stimulate their interest individually. Dean says: An important part of the teachers role is to stimulate and interest children in whatever is to be learned. This is a valuable part of working with the whole class (2001: 62) Before I sent the children to their tables to undertake their written activities, I ensured I explained and showed the children what I expected them to do, which aided their understanding. Teachers need to know the extent of their childrens mathematical abilities in order to set appropriate activities, so as this was my first maths session I had to ask the class teacher to help me with this. OBrien and Guiney believe planning towards differentiation is imperative and should be seen as integral to learningIt is a concept that has to be seen in an inclusive way, applying to everyone. (2001: ix) Therefore although children had the same learning objective, they recorded their answers in different ways. The lower ability pupils had to colour in the requested numbers on a number square, where as the other children had to write the numbers, which tested all children whilst allowing them to work at their own pace. When the children applied their mathematics on their tables I ensured myself a nd the LSA worked with different groups in different sessions, so all children did not become too reliant on support and have the opportunity to work independently. Ball agrees saying you have a choice between killing your pupils interest and giving them a taste for independent thinking. (2002: 17) The activities the children were completing all involved adding and subtracting multiples of ten, however children had completed addition problems first so assumed the whole activity contained addition problems. Briggs and Davis say: Here the child immediately sees something familiar within the task and assumptions about the level of attention needed to complete the task. (2008: 47) In future I will inform the children that there is a variety of symbols within their work so they need to read the number sentence before working out the answer. Giving children a number square to use, however, did assist them with their learning as they could visually picture the numbers and see what they had to do to get the answer. The higher ability pupils struggled with partitioning numbers, so they resorted back to the more familiar method of counting on or back to the required numbers. Although they did not use the required method, they still referred back to their previous knowledge and applied it to their work. Mooney et al say children tend to use those that they have confidence with, which are likely to be earlier strategies that pupils revert to if not clear about new ways of working. (2009: 15) Ofsted (2001) believe that the plenary session is the least successful part of the daily mathematics lesson. Therefore I wanted to ensure my plenary was not occupied by tidying up and that it did not become a reporting-back session for the children I had not worked with. This is why I set up a challenge of matching questions to the relevant answer, which would enable me to see what the children had learned or were struggling with. You have to demonstrate that you enjoy teaching, then challenge and assist children by engaging them with well-paced differentiation and thinking rationally about their needs, before being able to take positive action to increase their quality of learning. I am hoping that as they master information and skills, they not only learn more content, but will also become more able and motivated to take responsibility for their own learning. I am also hoping that I can develop a wider range of skills, and the knowledge of when to use them.

Cast System in india

History of the Indian caste system From Wikipedia, the tree encyclopedia Jump to: navigation, search Indian society has consisted of thousands of endogamous clans and groups called latis since ancient times. The Brahmlnlcal scriptures and texts tried to bring this diversity under a comprehensible scheme which hypothesised four Idealised meta groups called varna.The first mention of the formal varna Indian caste system Is in the famous Purusha Sukta of the Rigveda, although it is the only mention in the entire body of the Vedas and has been decried as a much later, non-Vedic insertion y numerous Indologists like Max M?ller and also by Ambedkar.

The Manu Smriti belongs to a class of books that are geared towards ethics, morals. nd social conduct – not spirituality or religion. Emergence of rigid caste structures In its later stages, the caste system is said to have become rigid, and caste began to be inherited rather than acquired by merit. In the past, members of dfferent castes would not partake in various activities, such as dining and religious gatherings, together. In addition, the performance of religious rites and rituals were restricted to Brahmins, who were the designated priesthood. Mobility across the castes The view ot the caste system as â€Å"static and unchanging† has been disputed by many scholars.For Instance, sociologists such as Bernard Buber and Marriott McKlm describe how the perception of th e caste system as a static and textual stratification has given way to the perception of the caste system as a more processual, empirical and contextual stratification. Other sociologists such as Y. B Damle have applied theoretical models to explain mobility and flexibility in the caste system in India. [2] According to these scholars, groups of lower-caste individuals could seek to elevate the status of their caste by attempting to emulate the practices of higher castes.Some scholars believe that the relative ranking of other castes was fluid or differed from one place to another prior to the arrival of the British. [3] According to some psychologists, mobility across broad caste lines may have been â€Å"minimal†, though sub-castes (Jatis) may change their social status over the generations by fission, re- the question of rigidity in Caste. In an ethnographic study of the Coorgs of Karnataka, e observed considerable flexibility and mobility in their caste hierarchies. [5][6 ] He asserts that the caste system is far from a rigid system in which the position of each component caste is fixed for all time.Movement has always been possible, and especially in the middle regions of the hierarchy. It was always possible for groups born into a lower caste to â€Å"rise to a higher position by adopting vegetarianism and teetotalism† i. e. adopt the customs of the higher castes. While theoretically â€Å"forbidden†, the process was not uncommon in practice. The concept of anskritization, or the adoption of upper-caste norms by the lower castes, addressed the actual complexity and fluidity of caste relations. Historical examples of mobility in the Indian Caste System among Hindus have been researched.There is also precedent of certain Shudra families within the temples of the Shrivaishava sect in South India elevating their caste. [2] Reform movements There have been cases of upper caste Hindus warming to the Dalits and Hindu priests, demoted to outc aste ranks, who continued practising the religion. An example of the latter was Dnyaneshwar, who was excommunicated from society in he 13th century, but continued to compose the Dnyaneshwari, a Dharmic commentary on the Bhagavad Gita. Other excommunicated Brahmins, such as Eknath, fought for the rights of untouchables during the Bhakti period.Historical examples of Dalit priests include Chokhamela in the 14th century, who was India's first recorded Dalit poet, Raidas, born into Dalit cobblers, and others. The 1 5th- century saint Ramananda also accepted all castes, including untouchables, into his fold. Most of these saints subscribed to the Bhakti movements in Hinduism during he medieval period that rejected casteism. Nandanar, a low-caste Hindu cleric, also rejected casteism and accepted Dalits. [7] In the 19th century, the Brahmo SamaJ under Raja Ram Mohan Roy, actively campaigned against untouchability.The Arya SamaJ founded by Swami Dayanand also renounced discrimination agains t Dalits. Sri Ramakrishna Paramahamsa founded the Ramakrishna Mission that participated in the emancipation of Dalits. Upper caste Hindus, such as Mannathu Padmanabhan also participated in movements to abolish Untouchability against Dalits, opening his amily temple for Dalits to worship. While there always have been places for Dalits to worship, the first â€Å"upper-caste† temple to openly welcome Dalits into their fold was the Laxminarayan Temple in Wardha in the year 1928 (the move was spearheaded by reformer Jamnalal Baja]).Also, the Satnami movement was founded by Guru Ghasidas, a Dalit himself. Other reformers, such as Mahatma Jyotirao Phule also worked for the emancipation of Dalits. Another example of Dalit emancipation was the Temple Entry Proclamation issued by the last Maharaja of Travancore in the Indian state of Kerala in the year 1936. The Maharaja proclaimed that â€Å"outcastes should not be denied the consolations and the solace of the Hindu faith†. Ev en today, the Sri Padmanabhaswamy temple that first welcomed Dalits in the state of Kerala is revered by the Dalit Hindu community.The 1930s saw key struggles between Mahatma Gandhi and B. R. Ambedkar, most notably over whether Dalits would have separate electorates or Joint electorates with reserved seats. The Indian National Congress was the only national organisation with a large Dalit following, but Gandhi nalysis of Untouchability, but lacked a workable political strategy: his conversion to Buddhism in 1956, along with millions of followers, highlighted the failure of his political endeavours. 8] India's first Prime Minister, Jawaharlal Nehru, based on his own relationship with Dalit reformer Ambedkar, also spread information about the dire need to eradicate untouchability for the benefit of the Dalit community. In addition, other Hindu groups have reached out to the Dalit community in an effort to reconcile with them, with productive results.
