Why Npv Is the Best Method for Project Appraisal Free Essays

A rational capital budgeting functionality should answer two major questions. First is that, whether one particular project is a good one? Second, if we get more than one available project opportunities, but we should choose only one of them, which one should be that â€Å"one†? In real life we very frequently come across with question like whether to pick up a lump some payment of retirement account accumulated during years or receiving monthly retirement pensions until the rest of our life. In this case, NPV is the most appropriate answer out of two or three most widely used techniques in capital decision making. We will write a custom essay sample on Why Npv Is the Best Method for Project Appraisal or any similar topic only for you Order Now While doing so we also should keep in mind two major features of NPV: 1) in monetary terms, NPV is the difference between today’s market value of the investment and its original cost. 2) a financial manager should always act on behalf of the interests of shareholders through distinguishing and picking up projects with positive NPV, since it’s very clear that the ultimate target of any investment is the maximization of owners’ wealth. Another major characteristic of NPV is that they cannot be straightforwardly originated in the market, so they need to be estimated. Since there’s always the possibility of a poor estimation, financial managers need to use a number of other criterions for project evaluation for additional information regarding whether or not an investment has a positive NPV indeed. (fundamentals corporate finance) Internal rate of return and payback period are the major evaluation tools used by supervisors as an alternative to NPV. It might be feasible to use mentioned methods during evaluation process as well, however each of these methods has very significant shortcomings. For example: Major drawback of IRR is that it states the result in terms of percentage rather than through monetary amounts (variances in scale). Comparison through only percentage results while considering the overall purpose of maximization of shareholders’ wealth can be a misleading approach during evaluating investments. (Atrill/McLnaey) Then when assessing mutually exclusive projects IRR rule can lead to an incorrect decision making, due to its reinvestment assumptions. The assumption of reinvestment of proceeds derived from the project supports the consideration of superiority of NPV over IRR. According to the assumption if NPV is accepted then the cash flows derived from the project could be reinvested maximum as the cost of capital. But IRR assumes that all cash flows from the investment can be reinvested with the same IRR of the original project. Theory states that, a firm should take all projects which a return that exceeds the cost of capital but any other available funds could only be reinvested at the cost of capital and this assumption is consistent with NPV approach mentioned. drury) Major shortcomings of payback period can be concluded as 1) ignorance of cash flows beyond the payback period, 2) its failure to contribute to the owners’ wealth while it underlines taking projects that recover original costs most quickly and 3) its ignorance of time factor. For instance: If one borrows a student loan which has a payback period of 13 years, the full amount of the loan is due 13 years after the first payment, which occurs on an agreed-upon date. Over the course of the payback period, a borrower must either pay back the loan with his own finance take out a different loan to pay off the first. As a conclusion I would like to stress that, during project evaluation two essential facts should be considered thorugh a well-grounded method of assessment. The first one is the rule â€Å"cash is the king† (cash can be invested anyway or another when it’s available) and the second one is the time value of money. This suports the fact that the money is to be invested immediately where it could result in capital gain and. Then since purchasing power diminishes year by year due, the most correct method of the capital budgeting is the one that combines both the risk,inflation and time factors such as NPV.

Analysis Of Walmart Grocery Retail Chain †MyAssignmenthelp.com

Question: Discuss about the Analysis Of Walmart Grocery Retail Chain. Answer: Introduction Wal-Mart is engaged in the retail and wholesale operation around the world. The company is known for offering assortments of merchandises and other services at an everyday lower rate. In the recent time, the retail giant has more than 11,600 stores worldwide and deals with products ranging from electronics, clothing, foot wear, health and beauty along with grocery products. It is the worlds largest company by revenue that is approximately $480 billion as well as the largest private employer hiring more than 2.3 million employees (Anselmsson et al., 2016). The retail company undertakes many business strategies in its business activities including generic strategy and competitive strategy that has actually contributed to the success of the business. The successful business strategies of the organisation include product differentiation and the cost effective measure against the products. The study below consists of the analysis of Walmart grocery retail chain on the issues that the human resources department undergoes. Many big warehouses and stores are run by Wal-Mart stores. Walmart store was founded almost fifty years ago by Walton and his brother Bud in Bentonville USA hence named after their names. Yearly it sells over 300$ billion, hence considering it to be one of the most valuable companies in the world. In many times it has been considered to be one of the biggest employer with more than one and half million workers globally. It is estimated to have more than 11600 stores globally of which 80% are in USA. Studying the economic environment of Wal-Mart will be a key in addressing the analysis of the business. Also the macro and micro analysis due to its running worldwide will also be necessary. Furthermore, strategies which are operational will be necessary in knowing how Wal-Mart is run. Another area is the marketing mix with the four factors being the 4Ps that is the price, product, place and the promotion factors which will help in explaining both the successes and failures of Wal-Mart. Next, is the study of how the human resources of Walmart is managed. The main idea here being to understand the exact area because criticism has been brought about that Wal-Mart doesnt do well with its employees. Later, before i recommend on the case study, a SWOT analysis is done which will help in looking into Wal-Mart failures and the critics. The last step in the case study will be the conclusion, where there is a summary of all the issues studied and in existence in Wal-Mart company. Main and Sub-Objectives The below highlighted objectives will be illustrated in our study. MAIN OBJECTIVE SUB OBJECTIVES Knowing all retail sectors How the sector evolves? How importance each sector is to economy? The Environment Knowledge Understand context of PESTEL Five porter analysis Direct competitors analysis Operations of Walmart and its Processes analysis Layout study Operations analysis System quality analysis Human resources analysis Management of human resource and job quality analysis Understanding marketing mix Customer target study SWOT analysis Weakness studies and how to handle them Environment. PESTEL analysis will need to be made that is the Political, Economic, Social and technology factors that influences Wal-Mart directly or indirectly. In real world there exist so many forces that make a company to be more or less appealing in terms of industrial gains. This will be approached with use of five porters forces. PEST Many retail companies such as Wal-Mart act within a macro-environment meaning that the scope of what happens in the outside depends on how the company runs. Unlike in micro environments the company with the retail store cannot change as these change occurs but in macro environment they adapt to the change as they occur and according to business rules and objectives. The following below is a PEST analysis explanation. Legal Political. Law enforcement in USA is in charge of local police, while the police of the states provides services at the border. In our case regarding the legal and political laws that affect the retail industry we consider such(Jonathan, 2016): The issue about dictating what the company type of message will send to its customers trying to convince them about the tastes and preferences of the products. In case of any violation of these then some penalties will occur and fines must be met according to the set law in case such happens. Protection laws for customers This entails protection of customers from exploitation by companies in terms of pricing and quality standard of the sold goods. These laws ensure that customers buy goods at reasonable prices and the goods or services offered to them are worth the price. Seeking punitive damages These are personal injuries caused by the company to individuals. The injured person is guided by USA laws while seeking justice. Punitive damages occur when the companys actions are deemed to be reckless and in turn this results to physical or mental damages to individuals (LLP, 2013). Discount prices that are misled there exist laws that protect customers from being misled by companys unrealistic or fake discounts in order to impress their customers. For instance a company may suggest that a product goes for $350 dollars from $500 giving its customer a $150 discount when in reality the company had not sold the product at $500 before. This is termed as a misleading discount price. Therefore, the USA laws protect the customers from such deceptions which act as a bait to attract the customers. Use of misleading discount prices via advertisements or any other marketing procedure is against the law. Social America is mostly occupied by the white as the majority, followed by the blacks and the rest take the other percentage. The makes the US consumer to be determined and characterized for it being so powerful or even having greater demand. The launching of products depends on the fashionable style it is created upon and products consumer centric, hence creating an engagement with the customers. Micro Analysis Walmart is facing a lot of competition from many different countries who have different types of competition. With the use of specialization strategies stores like Target, Kmart, ShopKo will compete successfully against Walmart(Shelly, 2014). This will be explained in to details using the porters five forces. Threat of substitute services and goods One of the problem faced by Walmart is that it has very big retail stores but physically small in terms of size. Other retails have been competing with Walmart in Way that they specialize with one product with a motive 0f covering a wide range. This means that what one retails offer is likely to be found in other stores. This bring to an understanding that the retailers offering goods that are unique have an added advantage compared to their rivals. Threat of new entrants. Walmart should be aware that the E-commerce and M-commerce has competition thats high as we have very many new entrants. Entrance of new companies to the market may threaten the existence of those companies that have been there for a while. Competitive Rivalry within Walmart and the surrounding industry. The expansion in the whole world is making Walmart to face a lot of competitors from countries that are different. When it comes to individual they have very little bargaining power with the retail stores. Bargaining power of customers Force involved here makes buyers to put Walmart under pressure making it to relate to the laws within those specific territories in which Walmart operates. Bargaining power of suppliers. Walmart size can break a small supplier. This is because many companies depend on Walmart in buying their product and this makes the suppliers to have very little power against Walmart. Human Resource Analysis The workforce of Walmart is about 2.2M globally. Walmart has encountered many issues and lawsuits with its employees overall. The issues appointed and raised ranges from conditions which are poor for workers, Union that are have policies that are against Walmart, Little amount of money is paid as wage to its employees and lack of enough health care being just some of the bigger issues with relations to how Walmart relates to its employees. In addition to this, it has also been found that Wal-Mart does not pay the farmers well and in fact exploit them in terms of making payment to them (Sparrow, Brewster Chung, 2016). All these issues have led to massive rebellion among the employees and have questioned the HR policies of the organisation. Thus, it can be said that Wal-Mart is facing human resource issues related to the employees of the organisation that needs to be sorted out. Poor wages issues High employee turnover rate of about 70% indicates that many employees employed by Walmart leaves the retail one year after employment, hence explaining the above mentioned issues to being experienced in Walmart by the employees. Wage issue is a very big concern as many are employees are connected by the employer through the salary they receive from the work done. The main issues affecting Walmart is wages rates. When compared to other companies working as retail such as Shopko, Target and others their wage rate is very good and appealing when working with them unlike in Walmart where there is greater workforce but with less employee wage hence many workers are not able work for long. Poor Working Conditions issues The working conditions in Walmart has also been described as an issue in human resource as , it has been described and reported that Walmart has very small physical stores but very large stores of goods being squeezed in those stores. The mixing of different products and commodities within the same store has made the working condition unconducive in such a manner that the space is small but a lot need to be done within the small space. Child labor violation issues Third issue is the violation of child labor whereby there has been cases of Walmart being sued for employing childrens who are under 18 to work in their retails. Globally in most countries one is considered mature and ready to work after an age of 18 years. Globally attempt to exploit the young children through employment at tender change is violation on children and this termed as child labor. Employing Illegal workers issues Fourth issue brought about by Walmart is employing workers who are illegally not allowed to work in those departments in different retails national wide or globally. By illegal workers we mean those workers who doesnt the specific skills to handle such outlets. This has been experienced in Walmart as many strives to make their end meets. Employing illegal workers put the lives of the customers or consumers of their goods, products or commodities at risk for the lack of knowledge might lead to misunderstanding between them and hence tarnishing the business name. Opposition from Labor Unions Fifth issue is the opposition from the labor union. Walmart has been on the frontline to be criticised by Labor union in USA. The opposition from labor Union which is mostly due to results of Unsatisfied employees reporting them to the trade union for labor. Sex discrimination issues Gender discrimination in Walmart is also another issue. This has led to day to day rebellion within its employees as women are paid less as their work entails much of sales associates. This highest level of discrimination has led to Walmart being one of the largest discriminatory retail in terms of gender. Health Insurance issues Last issue and not least is the health insurance issue. Insurance cover for the employee working with Walmart has been an issue for a very long time. Retail is not a secure job because sometimes the materials or products handled might be toxic, flammable, poisonous, fragile etc. and this might need some cover as it is a risk one is taking to be part of the organisation that provides this services. Walmart failure to cover some of its employees and many issue arising when need for cover arises has been termed as a major issue in human resource. Swot Analysis The graft for clients appreciative is its solicitation to developing a strategy and implementing it. Once the client understands the process completely then the team that takes part in organizing the strategy will need to receive, then digesting it and then apply what they found in their analysis. Strategic planning context understanding through which a customer or client may think is through understanding the one way or of conducting the SWOT Analysis(Goodstein, 1993). This is client or customer way of understanding, as this analysis will provide the uniqueness in viewing Walmart retail store through its Strengths, weaknesses, Opportunities and Threats from mostly the clients point of view. Strengths Weaknesses Opportunity Threats Conclusion Maintaining and solidifying current customer value and developing tactics for meeting unanticipated emerging needs provides the basis for either developing or modifying an organizations strategic plan. It is this application that makes the customer understanding analysis pay off. Recommendations The issues brought about above are clear and evident that there is necessity of undertaking severe action in order to improve the human resource strategy in the organisation. As it has been found that the organisation has faced law suit for its ill behaviour and treatment against the employees, it is highly recommended that the HR policies should be developed keeping the employee guidelines of salary and their welfare. The human resource strategy should also include the training of the workers in order to increase their efficiency at work(Ravi.S.P, 2015) (Ravi, 2015). If there remains the opportunity, the management needs to consider the transfer of knowledge as well that would eventually help to improve the performance of the employees in the organisation. In addition to this, the company should also consider the importance of gender equality in the organisation that would help to overcome the blames that Wal-Mart is facing in the recent time. Walmart should address and adapt a corporate attitude that is friendly, because it has damaged its image because of its laborsuits towards their suppliers(Walmart, 2016). Another recommendation that should be considered is participating in charitable events as this will show some kind and make the world to be better. Lastly just like any other organization no matter how small or big it may be either nationally or globally, safety and health of the employee should be given priority. The priority here should be updating their health and medical insurance cover at all times as they might have issues that may arise during working hours and this covers will be highly needed. The working conditions of the employees should be large such that the stores and office have enough room for movement within as this will reduce the congestion that has been experienced in the already existing stores of Walmart globally. Conclusion Walmart should have initiated its business at a scale that is lower. This mistake led to the situation that it could not cope up with the benefits of economies of scale. Walmart by the name and looks have been seen as one of the best retailers in the world but in real sense it has led to many quitting jobs in other sectors so that they can be employed by them, to end up jobless as their needs and expectations are not met after being employed by them. In conclusion with regards to the issues studied and researched that seems to be experienced by Walmart human resource department, Walmart should take in to considerations of the above recommended solutions to issues brought about and this will eliminate most problems and make Walmart a better retail chain store.

Being and Been

Being and Been Being and Been Being and Been By Maeve Maddox Saad Khan asks to know the difference between being and been. Been is the past participle form of the verb to be. It is used with the auxiliary verbs has, have, and had to form perfect tenses: How long has it been since you were in Paris? He had been writing that novel for thirty years when he died. How long have you been living here? Being is the present participle form of the verb to be. It is used with the auxiliaries is, are, was, and were to form continuous tenses: Mary is being difficult. The letter is being written. It is used as a verbal, a word that partakes of both verb and noun: Being polite is more productive than being rude. The word being can also be used a noun meaning â€Å"creature.† No human being should be homeless. I watched a movie about a being from outer space. Being can also mean â€Å"existence.† We are called from nothingness into being. In the expression â€Å"for the time being,† it means â€Å"the present.† We’ll leave him in charge for the time being.

Pressure distribution on an ellipto-zhukovsky aerofoil Essay Example

Pressure distribution on an ellipto Pressure distribution on an ellipto-zhukovsky aerofoil Paper Pressure distribution on an ellipto-zhukovsky aerofoil Paper The pressure distribution around an Ellipto Zhukovsky aerofoil with a chord of 254 mm at a range of angles of attack (-4? , 7? and 15? ) was determined and pressure contributions to lift were evaluated in a T3 wind tunnel at City University. This was carried out at a chord Reynolds number of 3. 9 x 105. Graphs for lift and pitching moment coefficients were plotted against angles of attack. A graph for Cm and Cl was also plotted from which the aerodynamic centre was determined to be 23. 7%. The value of lift curve slope was determined to be 4. 4759. Hence the value of k (the ratio of the actual lift curve slope to the theoretical one) for this aerofoil was determined to be 0. 917. The value of Cmo was also found to be 0. 0172. Specimen calculations for 15 degrees angle of attack can be found in the appendix section.

K) T Temperature (K) Re Reynolds Number INTRODUCTION An airfoil is any part of an airplane that is designed to produce lift. Those parts of the airplane specifically designed to produce lift include the wing and the tail surface. In modern aircraft, the designers usually provide an airfoil shape to even the fuselage. A fuselage may not produce much lift, and this lift may not be produced until the aircraft is flying relatively fast, but every bit of lift helps. The first successful aerofoil theory was developed by Zhukov sky and was based on transforming a circle onto an aerofoil-shaped contour. This transformation gave a cusped trailing edge, and so the transformation was modified to obtain a slender semi-eclipse trailing edge, which gave rise to the name Ellipto Zhukovsky. When a stream of air flows past an aerofoil, there are local changes in velocity around the aerofoil, and consequently changes in static pressure in accordance with Bernoullis theorem. The distribution of pressure determines the lift, pitching moment, form drag, and centre of pressure of the aerofoil. In our experiment we are concerned with the effect of pressure distribution on lift, pitching moment coefficient (Cm), and centre of pressure. The centre of pressure can be defined as the point on the aerofoil where Cm is zero, and therefore the aerodynamic effects at that point may be represented by the lift and drag alone. A positive pressure coefficient implies a pressure greater than the free stream value, and a negative pressure coefficient implies a pressure less than the free stream value (and is often referred to as suction). Also, at the stagnation point, Cp has its maximum value of 1 (which can be observed by plotting Cp against x/c). Zhucovsky claimed that the aerofoil generates sufficient circulation to depress the rear stagnation point from its position, in the absence of circulation, down to the (sharp) trailing edge. There is sufficient evidence of a physical nature to justify this hypothesis and the following brief description of the Experiment on an aerofoil may serve helpful. The experiment focuses on the pressure distribution around the Zhucovsky airfoil at a low speed and the characteristics associated with an airfoil:  coefficient of lift,   coefficient of pitching moment   and centre of pressure. The airfoil is secured to both sides of the wind tunnel with pressure tappings made as small as possible not to affect the flow,(appendix- photo 1 . The pressure difference around the airfoil is measured with twenty-five manometer readings which are recorded for each angle of attack. The manometer fluid is alcohol and has a specific gravity of 0. 83 and inclined at an angle of 30 degrees. Tube 1 is left open to atmospheric pressure, while tubes 2-13 are the lower surface of the airfoil and tubes 14-24 are the upper surface of the airfoil. The pressure tapings are positioned on the airfoil at a distance x/c, noted in the results table and tube 35 is the static pressure of the wind tunnel. The dynamic pressure is given by a digital manometer. The digital readout results were used for all calculations because they are more precise. Results Raw data and calculated values for x/c, Cp and Cp(x/c) can be found in the appendix. Graphs of Cp against x/c for angles of attack -4, 7, and 15 degrees can be also be found in the appendix. These graphs determine the lift coefficient. Counting the squares method was used to determine the values of Cl. Graphs of Cp*(x/c) against x/c for angles of attack -4, 7, and 15 degrees can be also be found in the appendix. These graphs determine the pitch moment coefficient. Counting the squares method was used to determine the values of Cm. Graphs of Cl against angle of attack ,Cm against angle of attack, and Cm against Cl can be found in the appendix. Also below is a summary of the results: Angle of Attack (degrees) Cl Cm -4 -0. 513 0. 153 7 0. 740 -0. 166 15 0. 946 -0. 183 Discussion The experiment was conducted in a low speed, closed wind tunnel, operating at approximately 50% of its speed. The aerofoil was mounted in the wind tunnel and its pressure tapings connected to a manometer inclined at 30 degrees to the horizontal. The height of the liquid in each manometer tube represented the pressure acting on each of the aerofoil tapings. The pressure in the working section, and the pressure at the venturi inlet were taken into account, and a resulting wind tunnel velocity was displayed on a digital manometer. The Reynolds number was calculated (see appendix. Values of Cl and Cm for other angles of attack were obtained from other groups conducting the experiment, and were used to obtain more accurate graphs. It was also found that the slope of the Cl against angle of attack graph was 4. 4759, which was not relatively close to the theoretical value of 7. 105. The aerodynamic centre was calculated at 23. 7% of the chord length (from the slope of the Cm against Cl graph). It was found that the lift increased with angle of attack, up to a point where the aerofoil experiences stall, and a dramatic loss of lift occurs. As there was little change in the lower surface pressure distribution, the lift was mainly generated due to the upper surface suction. As the angle of attack increases, the height of the upper surface suction peak should increase, and move forward, indicating that the centre of pressure is moving forward. However, experimentally this was not prominent, and can be attributed to a possible disturbance in the pressure distribution around the aerofoil. At zero degrees angle of attack, for a symmetrical aerofoil, lift and Cm should equal zero. The reason that they were not zero means that the aerofoil must have had a very small angle of attack. The discrepancy between the theoretical and experimental value of lift curve slope is due to boundary layer effects, and the effect of the thickness of the aerofoil, and thus the theoretical value needs to be multiplied by the k value (=0. 917) to obtain the experimental result. Conclusion The aim of the experiment was achieved with a relatively good level of experimental accuracy. The pressure distribution over an aerofoil contributes towards the lift and pitching moment coefficient, where the increase in suction on the upper surface (due to an increased angle of attack) increases the lift, and pitching moment coefficient. The variation of pressure distribution also affects the location of the centre of pressure. The factors which affected the pressure distribution, were mainly the thickness and the Reynolds number. However, when it comes to comparing the results with their theoretical values it is clear to see that there have been significant errors have occurred in the experiment. These are listed below. Human errors in reading of the manometer tubes. Where several people were involved and this led to different techniques being used it would have been best for everyone to take their own set of readings and the average value calculated using all the data. The most common error without ant doubt was parallax and this could have been avoided by using digital measuring devices. Calculation errors i. e. rounding off, conversion error and error occurring when the area under the graphs was calculated for the coefficient of lift.   Experimental errors some of the tapping may have been defective and not enough tapping were provided. Also to obtain a better lift curve slope there should have more angles of attack. Also any obstructions in front of the wind tunnel such as people would create unnecessary turbulence inside the wind tunnel. Appendix Specimen Calculations.

Plate Tectonics Assignment Example | Topics and Well Written Essays - 250 words

Plate Tectonics - Assignment Example For example, by pouring cooking oil into a glass beaker halfway with water, it will be observed that the oil will be in motion. This motion is attributable to the interaction of the earth’s layers. The science of plate tectonics is testable. Plate tectonics- The theory of continental drift explains that the earth’s surface appeared different 300 million years ago (Young, Greg p. 26). The science behind plate tectonics indicates that the continents lie on multiple plates of the lithosphere, which are in a constant horizontal motion (like blocks of ice over the lake). Plate tectonics is attributable to the steady movement of the lithosphere. The blocks of lithosphere interact differently against each other. This brings about plate tectonic events that are experienced over the earth’s surface. The horizontal movement of the blocks of lithosphere is as a result of natural causes, which are not attributable to any human

F1 case Studay answering some questions using some markiting methodology - Assignment Example All Ferrari cars are red in colour representing Italy’s national colour. The factory at Maranello is a state of the art infrastructure and is an up-to-date facility. Ferrari cars have always been low on displaying their sponsors logo and names. Being one of the oldest companies in the business Ferrari has had its share of ups and downs. The journey has not been a smooth one for Ferrari. New Zealander Bruce McLaren, who was a F1 driver himself, founded by McLaren in 1966. McLaren registered its first victory in 1968 but the true dominance of McLaren was in the late 1980s and early 1990s. The domination was such that McLaren won 15 out of the 16 races in a year in the period. Williams was founded by Frank Williams and again Frank too was a driver. Williams lead the technological development in F1 that was triggered in the early 1990s. William dominated F1 from 1992 – 1994. 1975 – 1978 was a great time for Ferrari as it dominated F1. Ferrari bagged both drivers and constructors world championship in 1975 and followed it up with the constructors championship in 1976. The tragic accident of Lauda which kept him away from action for nearly 6 weeks was the reason that Ferrari could not get the drivers’ championship in 1976. Ferrari won both drivers and constructors championship in 1977, and the drivers’ championship in 1978. During this period Ferrari made few changes to its structure. Montezemolo was promoted to head the entire motorsport operations of Fiat, while Danielle Audetto was made Ferrari’s sporting Director. The strategy here was to replicate the success of Ferrari with Fiat. This strategy backfired as Audetto was not able to fill in the shoes of Montezemolo. He failed to develop a strong relationship with the lead driver and the design team. This eventually led to Lauda moving out of Ferrari. Also during this time, Ferrari became complacent and adopted a short-termed focused strategy wherein it tried to develop their

Dyscalculia: Causes, Effects and Interventions

Dyscalculia: Causes, Effects and Interventions ABSTRACT This project suggests briefly about the Dyscalculia and the possible biological bases of dyscalculia and about the people who is suffering from the dyscalculia and also mentioned about the problems that are facing by the dyscalculic people in different fields of areas in their daily life. Coming to this case of Dyscalculia it is defined as the mathematical and arithmetical inability while coming to the brief description it is named as Number blindness. Here in this project we focussed only on arithmetical addition and briefly describing problems facing by the dyscalculic people while doing mathematical addition and counting of numbers. And secondly we are going to describe how does dyscalculia comes from and the reasons and explain the relationship between Dyslexia and Dyscalculia as there is a chance to acquire dyscalculia from dyslexia. The main aim of the project is to teach the mathematical addition rule to the People with Dyscalculia would struggle in doing arithmetical addition. Before starting to teach the mathematical addition rule to the dyscalculics I already studied briefly about the dyscalculia and how does it occur and what are the Types of dyscalculia that occurs to the dyslexic people and the deficits intended in dyscalculic people as they expressing while doing mathematical addition. Now a days Dyscalculia is the main problem that are affecting people up to some extent. But not as much this is the problem mainly occurs which is connected with Dyslexia. However one thing should remember that all the Dyslexics are not Dyscalculics although 40% of dyscalculia occurs from dyslexia. In this project to overcome Dyscalculia particularly in the arithmetical addition and to teach the mathematical addition to the dyscalculics I designed application software in Flash with visual graphical design with the help of a colourful Cuisenaire rods. By studying about the previous sources that are useful to teach the maths addition which were designed by some experts in dyscalculia studies such as Brian Butterworth and some other experts on dyscalculia the teaching designs like Phonological loop, Visio spatial sketch pad etc,. Hence by following some of that specific designs in my view and I designed an understanding design to teach mathematical addition rule to dyscalculia people. This includes brief understanding and attractive designs that can impress the dyscalculic and make them enthusiastically towards to the learning of mathematical addition from the basic adding to the high level digits adding that means starting from single digit adding to higher level adding. For this we need to train them on the Cuisenaire rods and the colours and values which was assigned to them and then we need to teach them first by running the application software automatically and I designed the whole process of addition in this software from the advanced stage to the stage of getting result. After that I am conducting a quiz to test their ability and grip on addition after teaching by using the designed application. I hope this design can help the dyscalculia to overcome arithmetical addition inability up to a greater extent. Introduction First of all before starting of my project this document reflects and introduce about the project from its advanced stage to the conclusion in a simple and briefly explanation on which concept that I am doing my project. I started my dissertation on a special concept of human disabilities which is known as Dyslexia and its further effects on human life prospectus. Especially this discuss about the defect on humankind that are suffering with mathematical and arithmetical difficulties known as Dyscalculia. The effect of dyscalculia mainly refers the lacking of mathematical skills and concepts such as addition, subtraction, multiplication and division. Dyscalculia is the major problem that is affecting the human life in our daily activities mainly focuses on inability of basic mathematical concepts of adding and counting of things which performs vulnerable and inefficient out coming result while doing calculations and normal counting in our daily life The main aim of the project is to help the people who are suffering from Dyscalculia and its deficits. To perform the activities that can help to understand the mathematical concepts and to overcome the deficits of dyscalculia that is affecting the people in their real life. The way of designing and the implementation of the project can be able to pave the way for finding the right solution to solve the problems of dyscalculic people with which they are suffering and to overcome their deficits with which are having individually and its total scope is to enhance the possible ways of teaching methods of addition particularly for the dyscalculic in an understanding and in a possible way which can be capable by the dyscalculic. The whole project is designed as user friendly and can be able to the dyscalculic people who are suffering with learning difficulties particularly in arithmetic addition that is adding of numbers starting from the adding of single digit to the higher level addition. In the advanced stage of the project we introduced the design with colourful Cuisenaire rods with attractive colours so by introducing attractive features into the design so that the dyscalculics can show their interest on learning addition very faster and can show the efficiency to get the output result correctly with satisfaction. The entire work of the project is based on teaching of mathematical addition in an understanding way to the dyscalculic people with learning difficulties in mathematical addition. Particularly in adding and counting of numbers according to the situations in their daily life. The possible steps in designing the project which is very useful to dyscalculic; The simple way of designing the project can be easily to understand by the dyscalculic people. Operation is user friendly to dyscalculics Introduction of special features can attract the dyscalculics towards the learning process. They can show their interest on mathematical addition and can learn easily by understanding. Back ground; Dyscalculia; What is Dyscalculia; Dyscalculia is mainly defined as difficulties with numbers it is identified as the difficulty in counting the numbers and things fast and fluently with lack of grasping power. Why the people with dyscalculia are different? Individuals with dyscalculia have specific difficulty with numbers, despite exhibits good results in other areas. They may have great difficulties with counting and adding the numbers. The example of an arithmetic addition2+4 or 4+2 Prices in the shops like tendering the money and taking the change correctly. Normal identification of numbers and what those represent, e.g. which is bigger, 2500 or 2770? Does 100+100 = approximately 200 or2000. Judging of numbers instantly for example seeing there are 5 glasses on the table normal people can count immediately and respond quickly where as the dyscalculic need to count them and to respond slowly. Phone numbers, seeing of dates , time etc,. It shows that people having dyscalculia has to struggle to achieve successful goals in the field of employment than having disability. Dyscalculia is the main learning problem that affecting many individuals and it is termed as the learning of mathematic disability by the disabled. It states that dyslexia is identified as the difficulties in reading written text fast and fluently with lack of grasping capacity. On the other hand dyscalculia refers the difficulties with handling and carrying out specific mathematical operations such as addition, multiplication, subtraction, division. Relation between dyslexia and dyscalculia: Here the relation between dyslexia and dyscalculia is very obvious. However, there are some points of overlap. There is a variant of dyscalculia that could be called as dyslexic dyscalculia. This problem involves primarily difficulties in reading which leads to mathematical problems for the people and these are the problems that arise with reading numerical symbols or difficulties with reading with multi-digit numerals so that 14 becomes 41. If the error happens like this in the reading of a task then obviously the solution becomes incorrect. On the other hand dyscalculia can be recognized in the lack of mathematics concern the ability to quickly retrieve numerical facts such as adding small digit numbers like 4+5=9 from the memory. There are several indirect similarities between difficulties with reading and mathematics. A poor working memory is one of the more obvious. Dyscalculia is defined as the mathematical problems caused by working memory or evident in the tasks that must be solved mentally, in the head. In the time of calculation the student may run into great difficulties keep various numbers in the memory. The other case is problem of remembering longer instructions and commands. May be they can remember a short what was supposed to be done. The rest is forgotten, because the information was never stored in the memory. The earlier researches shows that people with dyscalculia also have dyslexia most of the people with dyscalculia can have only mathematical difficulties. And they have a highly specific form of a learning difficulty and many are good in reading. Nowadays the occurrence of both dyslexia and dyscalculia at the same time is diagnosed as icd-10. The most common thing in dyscalculia is the difficulty with the number order. Difficulties involve understanding and use of mathematical operations and concepts. People of large proportions with dyscalculia display problems with following calculations to reach a correct solution. They easily lose their strategy and therefore run into difficulties with complex mathematics. Students with dyscalculia can be able to solve mathematical tasks but with in a average time frame they are unable to retrieve numerical facts from their vulnerable memory and must expend a lot of energy doing The word dyslexia comes and originated from the Greek word Dys means impaired and lexia is a word. Dyslexia ranges from easy to severe conditions. There exist various forms of this disease. Therefore there are different types of symptoms of this illness. The individual features of every type are specified for every human being separately. In general there is no such a typical type of dyslexia. Dyslexia refers to be a learning disability of the brain especially difficulties in reading or writing and spelling and it is the disability of neurological disability. Due to dyslexia the main drawback is that the people with dyslexia failed to remember the name of the things or to connect the name of the item with the definition. Recent surveys revealed that girls are less dyslexic than boys. There are two kinds of dyslexia Genetic Acquired Genetic transfers with the genes and the second one that is acquired occurs to brain damage in the left hemisphere that is responsible for language areas. Possible causes of dyslexia; Dyslexia is widely recognised as having a genetic component for example if a one kid of a pair of twins is dyslexic and the other twin is more likely to be dyslexic in the areas specially in language processing dyslexia links with brain differences. Possible causes of dyscalculia; It suggests by evidence that dyscalculia may have a genetic component. If there exists dyscalculia in one identical twin most possibly there is a chance of around 70% to become dyscalculic characteristics in the other twin. For non identical twins there is a less possibility of getting dyscalculia around 55% only. Research facts of Dyscalculia; Brian Butter worth an expert in dyscalculia research facts; Simply Brian butter worth done some research on a particular person who has dyscalculia and he is describing about the situation of the particular person and his name is Charles. Brian Butterworth met Charles when his (Charles) age was 30 years old Charles is a good professor in psychology and getting psychology degree is an achievement for Charles. But entries to the university in the first place even though he is best he failed to normal condition for entry into the maths GCSE. Charles is intelligent and very hard-working. But he is very poor in number skills that always have been a severe handicap and shopping is a constant embarrassment he doesnt understand the product prices and unable to grasp the idea of the total cost of the shopping basket. When he comes to the till, he has no idea about the money how much to tender and to get correct change. At that time immediately he use to add and multiply his fingers, and he is unable to do the two digit arithmetic problems such as 47-19. The real surprise thing that Butterworth found here about Charles is he couldnt tell that which is bigger or which is smaller in a numbers list which were given for suppose 9 or 5 and to find the difference suddenly he started to count his fingers to work in out. Charles is an example and this condition is known as dyscalculia and this mainly affects the ability of acquire the skills in mathematical and arithmetical skills. Dyscalculic learners may face the difficulties in understanding the basic and simple arithmetical concepts like adding of single digit numbers. For simple arithmetical concepts they may face severe anxiety and they struggle to understand what is obvious to all their friends and classmates. Dyscalculics even if they produce a correct answer or use a correct method they may do so mechanically and with lack of confidence. This captures what many dyscalculics like Charles feel about maths it is incomprehensible. Dyscalculia is not only a problem for the individuals but also it is one of the effect to the nation and for some especially as from the published report of the basic skills agency shows that poor math skills is a bigger handicap to getting a job by having that poor numeracy the employee will transport the wrong number of goods and fails in the money transactions such as receiving or paid out the money. And due to this poor efficiency in calculations affects the particular company. The current estimations suggest that about 5-6% of average to the superior intelligence children will have a real deficit in doing maths. Dyscalculia seems to be particularly found in dyslexics around 40% of the people who struggles with reading difficulties also having difficulties in learning maths and the remaining 60%have no problems than normal. It was found already that there is link between dyslexia and math learning difficulties although the latter can occur alone. It is worth noting that learning about numbers is different from learning to read in an important way. We are born with basic numerical abilities. Infants, even in the first week of life, are sensitive to changes in the number of things they are looking at. We know this because they will look longer at a display when we change the number of things, but often will not when we change one of the things but keep the same number. Babies also seem to be able to do very simple arithmetic. If the baby sees a doll place behind a screen, and then another doll placed behind it, it can be shown that the baby expects there to be two dolls (1 + 1) when the screen is removed. Babies look longer at things they dont expect, and will look longer at one doll or three dolls in this situation. So there is evidence of an innate capacity for numbers. One hypothesis to explain dyscalculia is a lack this innate capacity. However we dont have a specialised capacity in reading by birth. Reading is a complex skill made up of various brain systems set up automatically to do the other tasks like language recognising visual patterns, sequencing, and so on. And some of these used to learn maths in school and deficits in them may also affect learning in mathematics. What we need urgently is a way of diagnosing dyscalculia, and separating it from all the other causes of maths problems, including inappropriate teaching. Once we can identify these children reliably, we can begin systematic research on how best to help them. Charles was not diagnosed as dyscalculic until he came into our lab, and, like many other dyscalculics, felt himself first to be incredibly stupid for not being able to do what all his friends could do easily. This was not good for his self-esteem, of course. After that he came to realise that there was something wrong, but he was completely immersed in the dark as what it could be. Better for his self-esteem, but of little practical help. We dont know there are how many cases like Charles, but we are slowly reaching there. Difference between dyscalculic and ordinary people in arithmetic calculations; Ordinary people; For suppose if there is a four dots or four things on a screener the ordinary people(without dyslexia) can identify the things which is on the screener and they can give instant reply with respect to the situation. So therefore the normal people can react very quickly and they can respond very quickly comparing to the dyslexic people. The grasping capacity is very good in the normal people. Dyslexic people (Dyscalculia); While coming to the dyslexic who suffers from dyscalculia cannot give the quick responses with respect to the situations like ordinary people. So to overcome this type of situations in dyslexic people we need to train them in such a way so that they can give their responses slowly in a particular way as the trainer and the people can understand a bit. In order to train the dyslexic people to overcome the problem of arithmetical difficulties we should introduce some specific designs which is very user friendly and comfortable to hold by the dyslexic people particularly who is suffering with dyscalculia. And the designing aspects should be able to overcome their deficits. Mathematical grasping capacity; This describes the mathematical ability of the dyslexic people and their mental ability of doing the mathematical calculations mainly the people who is suffering with dyscalculia. For suppose if we introduce any four kinds of things in front of the dyslexic people they cannot give the quick response by counting the things so they will take time to count one by one and starts 1,2,3,4 and will give the response very slowly as 1+1+1+1=4 So people suffering with dyscalculia unable to do bigger calculations like adding numbers which is in big units like 234+432 so therefore we need to train them in such a way from the earlier stages of addition like adding single digits 1+2=3 so we need to begin from the earlier stages of addition. And after that by observing their progress we should train them to the further stages like adding double digits and then 100s and 1000s and so on. Its very important to train them with respect their progress by observing their progress we can easily calculate their mental ability of doing the calculations and thereby we can implement the teaching techniques which can very easily and comfortable to the dyslexic people. So by introducing the new and comfortable techniques of teaching the people (dyslexic) can easily do the mathematical addition. Teaching of mathematical addition rule; To teach the Mathematical addition rule to the dyscalculia we need to train them in specific way. The mathematical symbol (+) is to be fix in their mind strongly. And to make them to learn its importance and its rule. Types and sub-types of dyscalculia; Developmental dyscalculia; It is referred as mathematical and arithmetical dysfunction in individuals with normal mental functioning, that results and occurrences of brain anomalies at the time of prenatal development. Discrepancy occurs between the mean mental age and math age there exists a neat and clear retardation in mathematical development. Problems encountered by pupils with dyscalculia; The will recognised and the observable things that generally we can find in the peoples with Dyscalculia are the learning and remembering difficulties in mathematical concepts like addition, subtraction, multiplication etc,. In this project especially we are focussing on the mathematical addition particularly and the difficulties which are the dyscalculics are facing in their real life in the fields of employment and in the living society and we had discussed the problems with dyscalcilia which they are facing in all the areas of everyday life prospectus. Leaving that matter about what we are talking above and coming to the point of the problems that are encountered by people about the problems of dyscalculia. The well recognised problems of dyscalculics; Difficulty in learning and remembering of mathematical concepts such as used in our daily life in our activities Ex; Addition In the time of interviews with teachers. Difficulty in remembering even up to the number bonds to 10 is the worst problem that pupils struggling with maths were up against. Difficulty in executing mathematics calculations procedures. In 1984 Russell and Ginsburg found a dyscalculic group of people struggling on both written calculation and arithmetical fact retrieval. In 1992 Yamashita and Aram found dissociation absence between arithmetical fact ability and procedural ability with numerical processing difficulties in pupil. In 1993 Geary suggests that procedural problems are likely to improve with experience and also suggests the retrieval difficulties are less likely to do so. And he proposes that the emerging of procedural problems is due to lack of understanding concepts. Problems of retrieval difficulties are the result of general semantic memory dysfunction. In 1999 Ostad has noted that the dyscalculia people use fewer procedures and often apply their smaller repertoire in the situations where they are not appropriate. Even the counting of simple and single digits were shown to be vulnerable in dyscalculic people Geary, Bow-Thomas and Yao in 1992 found that dyscalculic people are less likely to detect the counting errors than normal people. However, all these deficits occur by the lacking of the conceptual understanding of the basic ideas of the numerosity and arithmetical concepts. Good memory for arithmetical facts depends and can be able to convert and organise them into meaningful patterns. And coming to the poor memory it can arise when the fact make little sense to the people. The known information from the dyscalculic people was heard badly by themselves is that they cant remember what the teacher is saying about the mathematics. Even some simple tasks like counting and adding single digit numbers dyscalculic people show a kind of rigidity. Geary, Bow-Thomas and Yao in 1992 found that counting should do perfectly from left to right without skipping around. From all these we can find right thing from all these authors observations and description we should note very important thing here is that these people ( Dyscalculics) cant understand the conceptual things in mathematics. Coming to the normal people can understand quickly that objects can count in any order. Underlying processing deficits; It is one kind of the approach to study about developmental dyscalculia and this involves trying to see it as a consequence of cognitive deficits based on the understanding of the mathematical and arithmetic concepts. And all of these proposals have included. Weak phonetic representations An advantage of this approach is there is a possibility of finding exactly the co-morbidity between dyscalculia and dyslexia, as we can find that dyslexics known to suffer from these conditions. Geary and colleagues suggested that semantic memory difficulties are the main cause for the problems of developmental dyscalculics which they are experiencing in number facts. As well as the co-morbid reading difficulties frequently found with dyscalculia. It shows the evidence particularly the argument is based that dyscalculic people have the difficulties in learning and remembering arithmetic facts that this deficit occur by lacking of understanding of math concepts. Empirical evidence for a general semantic deficit in dyscalculic people is thin. In 2002 temple and Sherwood recognises that a group of dyscalculic people are suffering with arithmetical difficulties were slower at colour and object naming than controls. This comes to know their speed and accessibility is very low. However the authors argued a casual relationship between the arithmetical ability and the speed of access It shows that People may be slower especially dyscalculics while the time of processing information in 1997 Jordan and Montana showed that the dyscalculic people can do the mathematical calculation on being unlimited time but they cant perform like the normal people whereas normal people can do significantly in case of time limit In 1999 Mclean and Hitch compared the dyscalculia between the younger and the older people and found that the older people is performing the accuracy than the younger people in the time of solving the arithmetical and mathematical calculation. It reveals that the performance of the older people acquired due to the experienced things which they faced before in their daily life which is continuing from their early starting from the childhood. In 1989 Siegel and Ryan found that people with dyscalculia showing their weak performance only in the fields of arithmetic and mathematical fields such as counting and adding of numerical things but not in the fields of non-numeric. On the other hand that found the spatial working memory and some aspects of central executive function were poorer in the dyscalculic people. Moreover, in2002 temple and Sherwood tested dyscalculic people and controls on forward and backward digit span, word span and corsi blocks (a non-verbal test of working memory). This study reveals there is no difference between groups and no correlation between the working memory measures and arithmetic ability measures. SUBTYPING DYSCALCULIA; The study of developmental dyscalculia has evolved to its new division of approaching to identify dyscalculic subtypes according to the presence or absence of other disorders, in an attempt to highlight the underlying processes that are contributing to the co-morbidity of the disorders. One of the things that we should note is the important correlate of mathematic disability is reading disability. It is estimated that at about 40% who is suffering from the dyslexics also have dyscalculic problems with learning difficulties in mathematics. The one of the most common ways of dyscalculic sub typing is according to whether or not they have a co-morbid reading disability. The conditions that have been associated with dyscalculia are stated below. attention deficit hyperactivity disorder (ADHD) (Badian, 1983;Rosenberg, 1989; Shalev, Manor and Gross-Tsur, 1997); poor hand–eye co-ordination (Siegel and Feldman, 1983); poor memory for non-verbal material (Fletcher, 1985); poor social skills (Rourke, 1989) In 1993 shalev and gross-tsur examined a group of seven people with developmental dyscalculia and not responding to intervention. All the group of seven people were suffering from additional neurological conditions, up to dyslexia starting from petit mal seizures and is mentioned as ADHD. DEFICITS OF DYSCALCULIA; Phonological processing in dyslexia In the main case studies of dyslexia phonological processing takes an important role compare to other disorders like sensor motor disorder. This survey was again confirmed by the recent survey shows the 100 percent of samples for dyslexia was affected. This survey had an argument is that theory of phonological processing was the tautology compare it as an explanation. That phonology and the reading of the dyslexia are the two sides of the same coin. That means this awareness was explained more by the reading skill. If the phonological deficit was Leeds to a problem along with the phoneme awareness. The main problems of dyslexics of the phonological problems are rapid naming and the verbal short term memory. This is related to reading. In this we can understand that phonological awareness and the rapid naming deficits are the relatively independent. Phonology does not reduce to the awareness of naming and memory. Some of the aspects for the phonology dyslexics remain to be investigated. ADHD: Attention-Deficit/Hyperactivity Disorder is presented in the childrens. This is to cause the neurodevelopment disorder. This also most studied part for the people. ADHD public health dimensions are received relatively little interest. According to the survey of epidemiologic the distribution of ADHD around the population by the age, sex, and race and according to the socio economic status. The origins of the risk factors are preventable. In this scenario we are going to discuss few of the independent concepts those having independent case of definition for ADHD. Summarizing the epidemiologic data regarding prevalence. In the literature key gaps were identified and ended with few suggestions for the epidemiogic research. Magnocellular deficit Due to the perceptual deficits of the dyslexia reliability is the one of the problem. With this performance Macarthur proposed the theory. This is one of the heterogeneity dyslexic samples. Mainly the magnocellular is made link with the cerebella dysfunction. These measures are become very hard to incorporate into the routine assessment of the reading. Cerebella hypothesis applied to the dyslexia. Those agree the phenotype. It is the research of phenotypes. With that we can clearly as showed the symptom complex. Auditory deficits; Auditory deficit is defined as the deficiency in one or more behavioural phenomena listed below for suppose deficit in. Auditory discrimination Auditory performance with degraded signals Auditory performance with competing acoustic signals Sound localization and lateralization These mechanisms lead to nonverbal as well as verbal signals and may affect many areas of function. Including speech and language and auditory deficit can delay the maturation in the development of the important auditory centres within the brain. The deficits are related to maturity differences in the developing stages of the brain. And usually auditory deficits represents more static types of problems and these deficits can be caused by tumours, trauma, degenerative disorders, viral infections, surgical compromise, lead poisoning, lack of oxygen auditory deprivation, and so forth. Prevalence of auditory deficits is estimated to be between 2 and 3% and we can observe more in males is often co-exists with other disabilities. And they include speech and language disorders or delays, learning disabilities or dyslexia, attention deficit disorders with or without hyperactivity. Dieted by the reminder of the hypothesis. Learning memory deficits in children; Children having learning disabilities such as dyslexia and dyscalculia. These are tending to may experience the core skills of the reading, writing and the arithmetic operations. These problems are raised at the first days of school. Even if we pass an instruction it needs to
