Trains essays Maglev trains may very well be the future of transportation. They are currently being developed in Germany and Japan, and other places around the world, like California in the United States of America, are planning whether getting a maglev train system would be worthwhile. Maglev trains are the fastest, most sensible form of ground transport available at this time, and with the demands of the transport system growing every year, they are bound to become a valuable part of the worlds transportation system. Maglev trains basically work by the simple principle that opposite poles attract, and similar poles repel, but in reality it is much more complex than this. Maglev trains work by gliding over the rails instead of rolling on them, and so do not create any friction on the rails while they are moving. Unlike all other forms of transportation, the system which causes the movement is not in the vehicle itself, but is in the guide way, or rails, beneath the train. These guide ways contain iron stator (a stator is the coil while the magnets is the rotor) packages containing 3-phase cables, and the vehicle is able to levitate when the guide ways attract the support magnets on the train. The train is kept on the rails by lateral guidance magnets which hold the vehicle to the guide way. This system may be compared to an electric motor where the stator has been flattened along the guide way. The train is able to accelerate when the propulsion system is switched on using the cable windi ng. The guide way is able to pull the train along because of the electromagnetic travelling field that is on while the propulsion system is running. The support system of the train is therefore able to become a rotor', which along with the stator, completes the motor'. (MVP Versuchs- un planungsgesellschaft fur Magnerbahnysteme m.b.H., 1999) Because the active part of the propulsion unit is built into the guide way as opp...

Challenges of gay people serving in the military - Research Paper Example The USAF has worked over the years in alliance with many countries, building strategic partnership for acquiring and maintaining Ã¢â¬Å"access to foreign territories for operational purposesÃ¢â¬ (Moroney et al, 2010, p.xiii). The USAF has revised their Mission Statement during 2005 to conform to the needs of the time, and its present mission is to Ã¢â¬Å"fly, fight and win... in air, space and cyberspaceÃ¢â¬ (Our Mission, 2012a). In order to achieve the objectives of their mission, the members of the Air Force uphold the vision of Ã¢â¬Å"Global Vigilance, Reach and Power,Ã¢â¬ which spans into the concept of Ã¢â¬Å"three core competencies: developing Airmen, technology to war fighting and integrating operationsÃ¢â¬ (Our Mission, 2012a). USAF is an organization of high ethical values, and they function within the framework of three values that comprise the concepts of Ã¢â¬Å"Integrity First, Service before Self and Excellence in All We DoÃ¢â¬ (Our Values, 2012b). ... hip and members of this organization, while discharging their responsibilities, have to consider the interests of different stakeholders including the national government, the citizens, other friendly countries, and the overall interests of the international community in making this world a better place for humans to dwell on. Therefore, all personnel who serve the Air Force have to imbibe in them a high sense of integrity, moral, ethics, and other values that the organization upholds. Similarly, leadership, being the most crucial element in determining the right direction for organizations to achieve their goals, the role of leaders in upholding the tenets of USAF, becomes paramount. Thus, when the organization manifests even a slightest indication of any perceived deviation from its projected image in the public eye, the leadership will have to bear the brunt of criticism. Unfortunately, despite their elite status and the high degree of performance, leaders of the organization have come under the flakes of disapproval on allegations of discrimination against gays and lesbians. In this context, the sexual orientation of a person is his or her absolute right and no force on the Earth has any reason to question its validity. Similarly, there is no acceptable justification for discriminating people on the basis of their sexual preferences. Humans, in spite of their claims of being sophisticated, nurture certain notions, deriving from established norms, and categorize peculiar behaviors that do not fall into their definition of accepted way of life as taboos. Thus, they consider gay and lesbian individuals as deviant and outcast them from the mainstream society. When the society upholds the value of human rights to all, without any regard to the attributes of ethnicity,

About a movie called (The Brother Grimm) - Essay Example The two move to a part of Germany occupied by the French in the 19th century and set up a phony witch. They use the fake witch to trick the residents of the Karlstadt of their mystical powers. The two brothers do their tricks so successfully that when a trouble befalls the city, the French General Delatombe summons them and tasks them with resolving the mystery. However, the mystery is an actual problem with real risks. A supernatural queen needs to drink the blood of young girls in order to regain her beauty. She, therefore, captures young girls from the village. The general tasks the two brothers with finding the queen, defeating her supernatural powers and rescuing the girls. The adventure thereafter is exhilarating as the two brothers fail twice and are on the brink of losing their lives. However, they eventually succeeded after a series of attempts. They rescue the village from the horrific queen. The film is an independent production directed by Terry Gilliam. Terry Gilliam is an American film director, actor and screenwriter. He contributed to writing and later directed the film. He has directed numerous other films some of which are adventure films. The Adventures of Baron Munchausen produced in 1988 was one of the adventure films he directed. However, The Brothers Grimm is unique as the director adopts a fiery tale approach in the development of the film. He produced the Brothers Grimm in 2005, a period when the film industry globally was burgeoning. The film, therefore, portrays the development of the film industry as Terry Gilliam revamps his creativity in authoring the script and directing the film. The developers of the film employ various elements of film development strategically thereby enhancing the effectiveness of the film. Key among such elements in the film is lighting. Lighting plays an integral role in illuminating the setting among other

Animals In Captivity Essay In 2008 at the Singapore Zoo, three white Bengal tigers attacked and mauled a zoo cleaner, Nordin bin Mondongto, to death after the man walked through a moat surrounding their enclosure. Researchers asked themselves what would be the cause of these vicious behaviors being reported from many zoos across the globe, the answer being the harsh environment zoo animals are surrounded by. Many people are not aware of the harsh treatment the animals endure. Zoos, circuses, and famous attractions like SeaWorld do not offer the best of circumstances for their animals. These uncomfortable conditions may be the cause of the hundreds of violent behaviors being reported by zoos around the world. Of course, most families enjoy taking a trip to the zoo because they offer a unique experience of encountering exotic animals. However, people need to realize that animals are living creatures that should not be forced into show, or held behind glass walls to be gawked at. The first point that this essay will address is the simple fact that zoo owners have propaganda in mind, and not preservation. Ã¢â¬Å"Zoos help save endangered species, by saving hurt animals and rehabilitating them,Ã¢â¬ is an excuse many zoo officials use. Zoos claim to want to protect species from extinction, which sounds like a noble goal, but zoo officials usually favor exotic or popular animals, rather than threatened or endangered local wildlife. The Chinese government, for example, Ã¢â¬Å"rentsÃ¢â¬ pandas to zoos worldwide for fees of more than $1 million per year. It is questi onable whether the profits are being directed toward panda-conservation efforts at all. Also, because tigers are the most favorable Ã¢â¬Å"crowd pleasers,Ã¢â¬ recent studies prove that there are more tigers in captivity than those that exist in the wild. There are thought to be between 5,000 and 10,000 tigers in U.S. cages and 90% of them are in miserable roadside zoos, backyard breeder facilities, circus wagons and pet homes. Before long, the few tigers left in the wild will wither off, and the animals in captivity will not be able to be relocated and thrive in their what-once-was natural environment. Next, the reader should know that the animals that are said to be Ã¢â¬Å"in their natural habitat,Ã¢â¬ are in confined areas that are less than a tenth of the area they would naturally be in, and are restricted by many factors. BirdsÃ¢â¬â¢ wings may be clipped so that they cannot fly, aquatic animals often go without adequate water, and many animals who naturally live in large herds or family groups are kept isolated. Animals are closely confined, lack privacy, an d haveÃ little opportunity for mental stimulation or physical exercise. These abnormal conditions often result in abnormal and self-destructive behavior, known as Ã¢â¬Å"zoochosis.Ã¢â¬ An Oxford University study based on decades of observing animals in captivity and in the wild found that animals such as polar bears, lions, tigers, and cheetahs Ã¢â¬Å"show the most evidence of stress and/or psychological dysfunction in captivityÃ¢â¬ and concluded that Ã¢â¬Å"the keeping of naturally wide-ranging carnivores should be either fundamentally improved or phased out.Ã¢â¬ Last but not least, the reader should know that keeping animals in captivity is not the only danger posed at the zoo. Even when the animals are bred in captivity, generations later, exotic animals will retain all of their natural instincts. They cannot be considered Ã¢â¬Å"domesticatedÃ¢â¬ or Ã¢â¬Å"tamed.Ã¢â¬ Every year, captive, exotic animals are involved in incidents in which humans are injured or even killed. In 2007, Tatiana, a Siberian tiger, escaped her substandard enclosure at the San Francisco Zoo and was shot to death after she killed one person and injured two others. This was not the only fatal incident occurring because of the animals being held in captivity. On February 26, 2010, a 12,000 lb. Orca whale called Tilikum mauled and killed his trainer Dawn Brancheau at SeaWorld during a performance. Also, in Colorado, on April 24, 2009, a volunteer was vigorously mauled by a tiger at Ã¢â¬Å"Big Cats of Serenity Springs.Ã¢â¬ The list of these aggressive outbreaks goes on and on. Researchers say that the awful conditions animals are unnatural and are the cause of animals expressing abnormal behaviors. Zoos may be fun for the family, but are definitely not fun for the animals. Taking animals out of their natural habitat, forcing them to live miserable lifestyles, and putting humans at risk is not worth a fun family trip to the zoo. Treating living creatures like they have no feelings is never okay and should be considered inhumane. Zoos need to be exposed as the pitiful prisons they are, and actions should be imposed to stop the animal abuse.

Light is a kind of electromagnetic radiation. It is made up of vibrations between a certain group of frequencies. When light is given off from a source it spreads out over a larger area. Scientists are still dumbfounded by exactly what light is. When light hits a smooth or polished surface it "bounces" off at the same angle that it hit. Reflecting telescopes are made of concave mirrors and they have helped astronomers chart the universe because the mirrors interact with each other to magnify what is being observed. Refraction is when light bends as it goes through glass, water and other transparent objects that are denser than air. A prism is an instrument that spreads out a ray of light into the color spectrum. A lens is another instrument that uses the light refraction, but lenses are put to more practical uses (IÃ¢â¬â¢m not saying that a mirror isnÃ¢â¬â¢t practical enough.). ______________________________________________________________________ Welcome to the wonderful world of light, including the refraction and reflection of light. Refraction is the bending of light when it travels through a denser, or thicker material, such as water. Reflection is a bit different though; when light hits a smooth or polished surface it "bounces" off the surface at almost the same angle (Depending on how flat the surface is.). But before we get onto that, lets talk about light and exactly what it is. THE NATURE OF LIGHT Light is a kind of electromagnetic radiation, which means, that they are magnetic waves and particles which are caused by electricity. Light consists of very fast oscillations at a certain group of frequencies, that can be detected by the human eye. When light vibrates at different frequencies the eye sees different colors. When light is emitted, or given off, from a source such as the sun, it moves in straight lines, and starts to filter out into a broader area as it travels farther. If it is interrupted by an object it will have an alteration in its course. Many Physicists as well as scientists are still puzzled by the nature of light. Sir Isaac Newton, an English physicist and mathematician, thought light of as a series of particles, because it was apparent that light moved in a straight line.

Lenses are put to many good uses such as refracting telescopes (Reflecting telescopes have concave mirrors), glasses, magnifiers, microscopes, and many other important things that we use in our every day lives. Light pays an important role in everyoneÃ¢â¬â¢s lives, basically we couldnÃ¢â¬â¢t see without it; but it has also confused many scientists and physicists whether light is a wave or a particle. Light travels in a straight line and spreads out over a larger area, but if it is interrupted by something its course changes. One thing that can change the direction of light is a hard, polished surface, such as a mirror. When a light hits a mirror it "bounces" off it at the same angle that it hit, if the mirror is flat (which most are). Another thing that can interrupt the travel of a light ray is a denser material than it was already in. This is called refraction, which is the bending of light. Prisms and lenses are pieces of glass that are specially designed to refract light rays and put them to use. Light can be mysterious in many ways, but in other ways it can be useful. bibliography Encyclopedia Britanica 1999 Light Paper -- essays research papers fc Light is a kind of electromagnetic radiation.

Ã¢â¬Ë Modern technology is capable of producing vast amounts of management accounting information but it has to be used to help managers to make good decisions and manage effectively. The emphasis in this paper is therefore on practical elements and application to the real world. The examiner does not want to trick you and papers will be fair. The F5 examiner The examiner for this paper is Ann Irons, who replaced Geoff Cordwell from the December 2010 sitting onwards.Ann Irons has written several articles in Student Accountant, including one on how to approach the paper (September 2010 issue). Make sure you read these articles to gain further insight into what the examiner is looking for. Syllabus update The F5 syllabus has been updated for the June 2011 sitting onwards. The full syllabus and study guide can be found in this Study Text on pages xi to xviii. The main changes are the omission of backflush accounting and the inclusion of environmental accounting and cost volume profit (CVP) analysis. The syllabus order has also been changed, which has been reflected in this Study Text.A full summary of the changes to the F5 syllabus is given on the next page.. Introduction vii viii Introduction Introduction ix 1 What F5 is about The aim of this syllabus is to develop knowledge and skills in the application of management accounting techniques. It covers modern techniques, decision making, budgeting and standard costing, concluding with how a business should be managed and controlled. F5 is the middle paper in the management accounting section of the qualification structure. F2 concerns just techniques and P5 thinks strategically and considers environmental factors.F5 requires you to be able to apply techniques and think about their impact on the organisation. 2 What skills are required? Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ You are expected to have a core of management accounting knowledge from Paper F2 You will be required to carry out calculation s, with clear workings and a logical structure You will be required to interpret data You will be required to explain management accounting techniques and discuss whether they are appropriate for a particular organisation You must be able to apply your skills in a practical context 3 How to improve your chances of passing Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ There is no choice in this paper, all questions have to be answered. You must therefore study the entire syllabus, there are no short-cuts Practising questions under timed conditions is essential. BPP's Practice and Revision Kit contains 20 mark questions on all areas of the syllabus Questions will be based on simple scenarios and answers must be focused and specific to the organisation Answer plans will help you to focus on the requirements of the question and enable you to manage your time effectively Answer all parts of the question.Even if you cannot do all of the calculation elements, you will still be ab le to gain marks in the discussion parts Make sure your answers focus on practical applications of management accounting, common sense is essential! Keep an eye out for articles as the examiner will use Student Accountant to communicate with students Read journals etc to pick up on ways in which real organisations apply management accounting and think about your own organisation if that is relevant 4 Brought forward knowledge You will need to have a good working knowledge of basic management accounting from Paper F2.Chapter 1 of this Study Text revises costing and brought forward knowledge is identified throughout the text. If you struggle with the examples and questions used to revise this knowledge, you must go back and revisit your previous work. The examiner will assume you know this material and it may form part of an exam question. x Introduction The exam paper Format of the paper The exam is a three-hour paper containing five compulsory 20 mark questions. You also have 15 min utes for reading and planning. There will be a mixture of calculations and discussion and the examiner's aim is to cover as much of the syllabus as possible.Syllabus and Study Guide The F5 syllabus and study guide can be found on the next page.

Questions in this paper will focus on interpretation rather than doing calculations. 1 Costing FAST FORWARD Costing is the process of determining the costs of products, services or activities.Cost accounting is used to determine the cost of products, jobs or services (whatever the organisation happens to be involved in). Such costs have to be built up using a process known as cost accumulation. In your earlier studies you will have learnt how to accumulate the various cost elements which make up total cost. Abso rption costing cost accumulation system 2 The problem of overheads FAST FORWARD Indirect costs, or overheads, are costs incurred in making a product or providing a service, but which cannot be traced directly to the product or service. Absorption costing is a means of incorporating a fair share of these costs into the cost of a unit of product or service provided.If a company manufactures a product, the cost of the product will include the cost of the raw materials and components used in it and cost of the labour effort required to make it. These are direct costs of the product. The company would, however, incur many other costs in making the product, which are not directly attributable to a single product, but which are incurred generally in the process of manufacturing a large number of product units. These are indirect costs or overheads. Such costs include the following. Ã¢â¬ ¢ Ã¢â¬ ¢ Factory rent and rates Machine depreciation Ã¢â¬ ¢ Ã¢â¬ ¢ Supervision costs Heating and lig hting 4 1: Costing ? Part A Specialist cost and management accounting techniques Key termsA direct cost is a cost that can be traced in full to the product, service or department that is being costed. An indirect cost or overhead is a cost that is incurred in the course of making a product, providing a service or running a department, but which cannot be traced directly and in full to the product, service or department. In some companies, the overheads cost might greatly exceed the direct production costs. It might seem unreasonable to ignore indirect costs entirely when accumulating the costs of making a product, and yet there cannot be a completely satisfactory way of sharing out indirect costs between the many different items of production which benefit from them. 2. Using absorption costing to deal with the problem of overheads Traditionally, the view has been that a fair share of overheads should be added to the cost of units produced. This fair share will include a portion of all production overhead expenditure and possibly administration and marketing overheads too. This is the view embodied in the principles of absorption costing. 2. 1. 1 Theoretical justification for using absorption costing All production overheads are incurred in the production of the organisation's output and so each unit of the product receives some benefit from these costs. Each unit of output should therefore be charged with some of the overhead costs. 2. 1. 2 Practical reasons for using absorption costing (a) Inventory valuations Inventory in hand must be valued for two reasons. i) (ii) For the closing inventory figure in the statement of financial position For the cost of sales figure in the income statement The valuation of inventories will affect profitability during a period because of the way in which the cost of sales is calculated. Cost of goods sold = (b) Pricing decisions Many companies attempt to set selling prices by calculating the full cost of production or sales o f each product, and then adding a margin for profit. Ã¢â¬ËFull cost plus pricing' can be particularly useful for companies which do jobbing or contract work, where each job or contract is different, so that a standard unit sales price cannot be fixed. Without using absorption costing, a full cost is difficult to ascertain. c) Establishing the profitability of different products This argument in favour of absorption costing states that if a company sells more than one product, it will be difficult to judge how profitable each individual product is, unless overhead costs are shared on a fair basis and charged to the cost of sales of each product. cost of goods produced + the value of opening inventories Ã¢â¬â the value of closing inventories 2. 2 Using marginal costing to deal with the problem of overheads For many purposes absorption costing is less useful as a costing method than marginal costing. In some situations, absorption costing can be misleading in the information it su pplies.Advocates of marginal costing take the view that only the variable costs of making and selling a product or service should be identified. Fixed costs should be dealt with separately and treated as a cost of the accounting period rather than shared out somehow between units produced. Some overhead costs are, Part A Specialist cost and management accounting techniques ? 1: Costing 5 however, variable costs which increase as the total level of activity rises and so the marginal cost of production and sales should include an amount for variable overheads. 3 A revision of absorption costing FAST FORWARD Absorption costing is a traditional approach to dealing with overheads, involving three stages: allocation, apportionment and absorption.Apportionment has two stages, general overhead apportionment and service department cost apportionment. Key term Absorption costing is a method of product costing which aims to include in the total cost of a product (unit, job and so on) an approp riate share of an organisation's total overhead, which is generally taken to mean an amount which reflects the amount of time and effort that has gone into producing the product. You should have covered absorption costing in your earlier studies. We will therefore summarise the simpler points of the topic but will go into some detail on the more complex areas to refresh your memory. Knowledge brought forward from earlier studiesAbsorption costing Ã¢â¬ ¢ Ã¢â¬ ¢ Product costs are built up using absorption costing by a process of allocation, apportionment and overhead absorption. Allocation is the process by which whole cost items are charged directly to a cost unit or cost centre. Direct costs are allocated directly to cost units. Overheads clearly identifiable with cost centres are allocated to those cost centres but costs which cannot be identified with one particular cost centre are allocated to general overhead cost centres. The cost of a warehouse security guard would therefore be charged to the warehouse cost centre but heating and lighting costs would be charged to a general overhead cost centre.The first stage of overhead apportionment involves sharing out (or apportioning) the overheads within general overhead cost centres between the other cost centres using a fair basis of apportionment (such as floor area occupied by each cost centre for heating and lighting costs). The second stage of overhead apportionment is to apportion the costs of service cost centres (both directly allocated and apportioned costs) to production cost centres. The final stage in absorption costing is the absorption into product costs (using overhead absorption rates) of the overheads which have been allocated and apportioned to the production cost centres. Costs allocated and apportioned to non-production cost centres are usually deducted from the full cost of production to arrive at the cost of sales. Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Question Cost apportionmentBriefly discuss the type of factors which could affect the choice of the bases an organisation can use to apportion service department costs. 6 1: Costing ?

Having allocated and/or apportioned all overheads, the next stage in absorption costing is to add them to, or absorb them into, the cost of production or sales. 4. 1 Use of a predetermined absorption rate Knowledge brought forward from earlier studies Step 1 Step 2 Step 3 The overhead likely to be incurred during the coming year is estimated. The total hours, units or direct costs on which the overhead absorption rates are based (activity levels) are estimated. Absorption rate = estima ted overhead ? budgeted activity level 4. 2 Choosing the appropriate absorption base Question Absorption basesList as many possible bases of absorption (or Ã¢â¬Ëoverhead recovery rates') as you can think of. Answer (a) (b) (c) (d) (e) (f) (g) (h) A percentage of direct materials cost A percentage of direct labour cost A percentage of prime cost A percentage of factory cost (for administration overhead) A percentage of sales or factory cost (for selling and distribution overhead) A rate per machine hour A rate per direct labour hour A rate per unit The choice of an absorption basis is a matter of judgement and common sense. There are no strict rules or formulae involved. But the basis should realistically reflect the characteristics of a given cost centre, avoid undue anomalies and be Ã¢â¬Ëfair'.The choice will be significant in determining the cost of individual products, but the total cost of production overheads is the budgeted overhead expenditure, no matter what basis of abs orption is selected. It is the relative share of overhead costs borne by individual products and jobs which is affected. Question Absorption rates Using the information in and the results of the question on page 7, determine budgeted overhead absorption rates for each of the production departments using appropriate bases of absorption. 8 1: Costing ? Part A Specialist cost and management accounting techniques Answer Machine shop A: Machine shop B: Assembly: $57,168/7,200 = $7. 94 per machine hour $63,000/18,000 = $3. 50 per machine hour $46,592/20,800 = $2. 24 per direct labour hour 4. 3 Over and under absorption of overheads FAST FORWARDUnder-/over-absorbed overhead occurs when overheads incurred do not equal overheads absorbed. The rate of overhead absorption is based on estimates (of both numerator and denominator) and it is quite likely that either one or both of the estimates will not agree with what actually occurs. Actual overheads incurred will probably be either greater tha n or less than overheads absorbed into the cost of production, and so it is almost inevitable that at the end of the accounting year there will have been an over absorption or under absorption of the overhead actually incurred. Ã¢â¬ ¢ Ã¢â¬ ¢ Over absorption means that the overheads charged to the cost of sales are greater than the overheads actually incurred.Under absorption means that insufficient overheads have been included in the cost of sales. Suppose that the budgeted overhead in a production department is $80,000 and the budgeted activity is 40,000 direct labour hours, the overhead recovery rate (using a direct labour hour basis) would be $2 per direct labour hour. Actual overheads in the period are, say $84,000 and 45,000 direct labour hours are worked. $ Overhead incurred (actual) 84,000 90,000 Overhead absorbed (45,000 ? $2) Over-absorption of overhead 6,000 In this example, the cost of production has been charged with $6,000 more than was actually spent and so the cost that is recorded will be too high.The over-absorbed overhead will be an adjustment to the profit and loss account at the end of the accounting period to reconcile the overheads charged to the actual overhead. Question Under and over-absorption The total production overhead expenditure of the company in the questions above was $176,533 and its actual activity was as follows. Machine shop A Machine shop B Assembly Direct labour hours 8,200 6,500 21,900 Machine usage hours 7,300 18,700 Ã¢â¬â Required Using the information in and results of the previous questions, calculate the under- or over-absorption of overheads.

Under or over recovery of overhead will occur in the following circumstances. Ã¢â¬ ¢ Ã¢â¬ ¢ Ã¢â¬ ¢ Actual overhead costs are different from budgeted overheads. The actual activity level is different from the budgeted activity level. Actual overhead costs and actual activity level differ from those budgeted. QuestionOver and under-absorption Elsewhere has a budgeted production overhead of $180,000 and a budgeted activity of 45,000 machine hours. Required Calculate the under-/over-absorbed overhead, and note the reasons for the under-/over-absorption in the following circumstances. (a) (b) (c) Actual overheads cost $170,000 and 45,000 machine hours were worked. Actual overheads cost $180,000 and 40,000 machine hours were worked. Actual overheads cost $170,000 and 40,000 machine hours were worked. Answer The overhead recovery rate is $180,000/45,000 = $4 per machine hour. (a) Actual overhead Absorbed overhead (45, 000 ? $4) Over-absorbed overhead $ 170,000 180,000 10,000Reason: Actual and budgeted machine hours are the same but actual overheads cost less than expected.

Part A Specialist cost and management accounting techniques 5 Marginal costing FAST FORWARD In marginal costing, inventories are valued at variable production cost whereas in absorption costing they are valued at their full production cost.Marginal cost is the cost of one unit of a product/service which could be avoided if that unit were not produced/provided. Contribution is the difference between sales revenue and variable (marginal) cost of sales. Margi nal costing is an alternative to absorption costing. Only variable costs (marginal costs) are charged as a cost of sales. Fixed costs are treated as period costs and are charged in full against the profit of the period in which they are incurred. Knowledge brought forward from earlier studies Key terms Marginal costing Ã¢â¬ ¢ In marginal costing, closing inventories are valued at marginal (variable) production cost whereas, in absorption costing, inventories are valued at their full production cost which includes absorbed fixed production overhead.If the opening and closing inventory levels differ, the profit reported for the accounting period under the two methods of cost accumulation will therefore be different. But in the long run, total profit for a company will be the same whichever is used because, in the long run, total costs will be the same by either method of accounting. Different accounting conventions merely affect the profit of individual periods. Ã¢â¬ ¢ Ã¢â¬ ¢ Quest ion Absorption and marginal costing A company makes and sells a single product. At the beginning of period 1, there are no opening inventories of the product, for which the variable production cost is $4 and the sales price $6 per unit.Fixed costs are $2,000 per period, of which $1,500 are fixed production costs. Normal output is 1,500 units per period. In period 1, sales were 1,200 units, production was 1,500 units. In period 2, sales were 1,700 units, production was 1,400 units. Required Prepare profit statements for each period and for the two periods in total using both absorption costing and marginal costing. Answer It is important to notice that although production and sales volumes in each period are different, over the full period, total production equals sales volume. The total cost of sales is the same and therefore the total profit is the same by either method of accounting.Differences in profit in any one period are merely timing differences which cancel out over a longe r period of time. Part A Specialist cost and management accounting techniques ? 1: Costing 11 (a) Absorption costing. The absorption rate for fixed production overhead is $1,500/1,500 units = $1 per unit.

(a) If inventory levels increase between the beginning and end of a period, absorption costing will report the higher profit because some of the fixed production overhead incurred during the period will be carried forward in closing inventory (which reduces cost of sales) to be set against sales revenue in the following period instead of being written off in full against profit in the period concerned.If inventory levels decrease, absorption costing will report the lower profit because as well as the fixed overhead incurred, fixed production ov erhead which had been carried forward in opening inventory is released and is also included in cost of sales. (b) 6. 2 Example: Reconciling profits The profits reported for period 1 in the question on page 11 would be reconciled as follows. Marginal costing profit Adjust for fixed overhead in inventory (inventory increase of 300 units ? $1 per unit) Absorption costing profit $ 400 300 700 Exam focus point Remember that if opening inventory values are greater than closing inventory values, marginal costing shows the greater profit. 14 1: Costing ?Part A Specialist cost and management accounting techniques 6. 3 Marginal versus absorption costing: reporting to management FAST FORWARD Marginal costing is more useful for decision-making purposes, but absorption costing is needed for financial reporting purposes to comply with accounting standards. We know that the reported profit in any period is likely to differ according to the costing method used, but does one method provide a more re liable guide to management about the organisation's profit position? With marginal costing, contribution varies in direct proportion to the volume of units sold. Profits will increase as sales volume rises, by the amount of extra contribution earned.Since fixed cost expenditure does not alter, marginal costing gives an accurate picture of how a firm's cash flows and profits are affected by changes in sales volumes. With absorption costing, in contrast, there is no clear relationship between profit and sales volume, and as sales volume rises the total profit will rise by the sum of the gross profit per unit plus the amount of overhead absorbed per unit. Arguably this is a confusing and unsatisfactory method of monitoring profitability. If sales volumes are the same from period to period, marginal costing reports the same profit each period (given no change in prices or costs). In contrast, using absorption costing, profits can vary with the volume of production, even when the volume of sales is constant.Using absorption costing there is therefore the possibility of manipulating profit, simply by changing output and inventory levels. 6. 4 Example: Manipulating profits Gloom Co budgeted to make and sell 10,000 units of its product in 20X1. The selling price is $10 per unit and the variable cost $4 per unit. Fixed production costs were budgeted at $50,000 for the year. The company uses absorption costing and budgeted an absorption rate of $5 per unit. During 20X1, it became apparent that sales demand would only be 8,000 units. The management, concerned about the apparent effect of the low volume of sales on profits, decided to increase production for the year to 15,000 units.Actual fixed costs were still expected to be $50,000 in spite of the significant increase in production volume. Required Calculate the profit at an actual sales volume of 8,000 units, using the following methods. (a) (b) Absorption costing Marginal costing Explain the difference in profits cal culated. Solution (a) Absorption costing Sales (8,000 ? $10) Cost of production (15,000 ? $9) Less: over-absorbed overhead (5,000 ? $5) $ 135,000 (25,000) (110,000) (30,000) 63,000 33,000 $ 80,000 Closing inventory (7,000 ? $9) Profit Part A Specialist cost and management accounting techniques ? 1: Costing 15 (b) Marginal costing Sales Cost of sales Cost of production (15,000 ? $4) Closing inventory (7,000 ? $4) Contribution Fixed costs Loss $ $ 80,000 0,000 ((28,000) 32,000 48,000 50,000 (2,000) The difference in profits of $35,000 is explained by the difference in the increase in inventory values (7,000 units ? $5 of fixed overhead per unit). With absorption costing, the expected profit will be higher than the original budget of $10,000 (10,000 units ? ($10 Ã¢â¬â 9)) simply because $35,000 of fixed overheads will be carried forward in closing inventory values. By producing to absorb overhead rather than to satisfy customers, inventory levels will, of course, increase. Unless th is inventory is sold, however, there may come a point when production has to stop and the inventory has to be sold off at lower prices.Marginal costing would report a contribution of $6 per unit, or $48,000 in total for 8,000 units, which fails to cover the fixed costs of $50,000 by $2,000. The argument above is not conclusive, however, because marginal costing is not so useful when sales fluctuate from month to month because of seasonal variations in sales demand, but production per month is held constant in order to arrange for an even flow of output (and thereby prevent the cost of idle resources in periods of low demand and overtime in periods of high demand). Question Absorption v marginal costing A clothing manufacturer makes a specific brand of jeans which it sells at a standard price of $100 per pair.

Under absorption costing, where inventories are increasing, a greater amount of the fixed production cost is carried forward n the closing inventory valuation than was brought forward in the opening inventory valuation. This means that the impact of these costs on profit is delayed under absorption costing. Under marginal costing, the full impact of the fixed production costs on profit is immediate. The business is profitable and sales have increased. However, a build up of inventories in the clothing manufacturing industry is unwise as demand is subject to tastes and fashion. The business needs to respond rapidly to changes in demand or it will become rapidly uncompetitive. Part A Specialist cost and management accounting techniques ? 1: Costing 17 Chapter Roundup Ã¢â¬ ¢ Ã¢â¬ ¢ Costing is the process of determining the costs of products, services or activities.Indirect costs, or overheads, are costs incurred in making a product or providing a service, but which cannot be traced directly to the product or service. Absorption costing is a means of incorporating a fair share of these costs into the cost of a unit of product or service provided. Absorption costing is a traditional approach to dealing with overheads, involving three stages: allocation, apportionment and absorption. Apportionment has two stages, general overhead apportionment and service department cost apportionment. After apportionment, overheads are absorbed into products using an appropriate absorption rate based on budgeted costs and budgeted activity levels. Under-/over-absorbed overhead occurs wh en overheads incurred do not equal overheads absorbed.In marginal costing, inventories are valued at variable production cost whereas in absorption costing they are valued at their full production cost. If opening and closing inventory levels differ profit reported under the two methods will be different. In the long run, total profit will be the same whatever method is used. Ã¢â¬ ¢ Marginal costing is more useful for decision-making purposes, but absorption costing is needed for financial reporting purposes to comply with accounting standards.

It was also examined in June 2008 and June 2010 and is therefore a crucial topic to understand. 1 Activity based costing FAST FORWARD /08, 6/10 An alternative to absorption costing is activity based costing (ABC). ABC involves the identification of the factors (cost drivers) which cause the costs of an organisation's major activities. Support overheads are charged to products on the basis of their usage of an activity. Ã¢â¬ ¢ Ã¢â¬ ¢ For costs that vary with production level in the short term, the cost driver will be volume related (labour or machine hours). Overheads that vary with some other activity (and not volume of production) should be traced to products using transaction-based cost drivers such as production runs or number of orders received. 1. 1 Reasons for the development of ABCThe traditional cost accumulation system of absorption costing was developed in a time when most organisations produced only a narrow range of products (so that products underwent similar operations and consumed similar proportions of overheads). And overhead costs were only a very small fraction of total costs, direct labour and direct material costs accounting for the largest proportion of the costs. The benefits of more accurate systems for overhead allocation would probably have been relatively small. In addition, information processing costs were high. In recent years, however , there has been a dramatic fall in the costs of processing information.And, with the advent of advanced manufacturing technology (AMT), overheads are likely to be far more important and in fact direct labour may account for as little as 5% of a product's cost. It therefore now appears difficult to justify the use of direct labour or direct material as the basis for absorbing overheads or to believe that errors made in attributing overheads will not be significant. Many resources are used in non-volume related support activities, (which have increased due to AMT) such as setting-up, production scheduling, inspection and data processing. These support activities assist the efficient manufacture of a wide range of products and are not, in general, affected by changes in production volume.They tend to vary in the long term according to the range and complexity of the products manufactured rather than the volume of output. The wider the range and the more complex the products, the more support services will be required. Consider, for example, factory X which produces 10,000 units of one product, the Alpha, and factory Y which produces 1,000 units each of ten slightly different versions of the Alpha. Support activity costs in the factory Y are likely to be a lot higher than in factory X but the factories produce an identical number of units. For example, factory X will only need to set-up once whereas Factory Y will have to set-up the 22 2a: Activity based costing ?Part A Specialist cost and management accounting techniques production run at least ten times for the ten different products. Factory Y will therefore incur more set-up costs for the same volume of production. Traditional costing systems, which assume that all products consume all resources in proportion to their production volumes, tend to allocate too great a proportion of overheads to high volume products (which cause relatively little diversity and hence use fewer support services) and too small a pr oportion of overheads to low volume products (which cause greater diversity and therefore use more support services). Activity based costing (ABC) attempts to overcome this problem. 1. Definition of ABC Key term Activity based costing (ABC) involves the identification of the factors which cause the costs of an organisation's major activities. Support overheads are charged to products on the basis of their usage of the factor causing the overheads. The major ideas behind activity based costing are as follows. (a) (b) (c) Activities cause costs. Activities include ordering, materials handling, machining, assembly, production scheduling and despatching. Producing products creates demand for the activities. Costs are assigned to a product on the basis of the product's consumption of the activities. 1. 3 Outline of an ABC systemAn ABC system operates as follows. Step 1 Step 2 Key term Identify an organisation's major activities. Identify the factors which determine the size of the costs of an activity/cause the costs of an activity. These are known as cost drivers. A cost driver is a factor which causes a change in the cost of an activity. Look at the following examples. Costs Ordering costs Materials handling costs Production scheduling costs Despatching costs Possible cost driver Number of orders Number of production runs Number of production runs Number of despatches Step 3 Step 4 Collect the costs associated with each cost driver into what are known as cost pools.Charge costs to products on the basis of their usage of the activity. A product's usage of an activity is measured by the number of the activity's cost driver it generates. Question Which of the following definitions best describes a cost driver? A B C D Any activity which causes an increase in costs A collection of costs associated with a particular activity A cost that varies with production levels Any factor which causes a change in the cost of an activity Cost driver Part A Specialist cost and mana gement accounting techniques ? 2a: Activity based costing 23 Answer D Any factor which causes a change in the cost of an activity. Exam focus pointABC is a popular exam topic. Questions on activity based costing often require a comparison with more traditional methods. The implications for the business of each approach is often required. 2 Absorption costing versus ABC 6/08, 6/10 The following example illustrates the point that traditional cost accounting techniques result in a misleading and inequitable division of costs between low-volume and high-volume products, and that ABC can provide a more meaningful allocation of costs. 2. 1 Example: Activity based costing Suppose that Cooplan manufactures four products, W, X, Y and Z. Output and cost data for the period just ended are as follows.Number of production runs in the Material cost Direct labour Machine Output units period per unit hours per unit hours per unit $ W 10 2 20 1 1 X 10 2 80 3 3 Y 100 5 20 1 1 80 3 3 Z 100 5 14 Direct labour cost per hour $5 Overhead costs Short run variable costs Set-up costs Expediting and scheduling costs Materials handling costs Required Prepare unit costs for each product using conventional costing and ABC. $ 3,080 10,920 9,100 7,700 30,800 Solution Using a conventional absorption costing approach and an absorption rate for overheads based on either direct labour hours or machine hours, the product costs would be as follows. W $ 200 50 700 950 10 $95 X $ 800 150 2,100 3,050 10 $305 Y $ 2,000 500 7,000 9,500 100 $95 Z $ 8,000 1,500 21,000 30,500 100 $305 Total $ Direct material Direct labour Overheads * Units produced Cost per unit 4,000 * $30,800 ? 440 hours = $70 per direct labour or machine hour. 24 2a: Activity based costing ? Part A Specialist cost and management accounting techniques Using activity based costing and assuming that the number of production runs is the cost driver for setup costs, expediting and scheduling costs and materials handling costs and that machi ne hours are the cost driver for short-run variable costs, unit costs would be as follows. W $ 200 50 70 1,560 1,300 1,100 4,280 10 $428 X $ 800 150 210 1,560 1,300 1,100 5,120 10 $512 Y $ 2,000 500 700 3,900 3,250 2,750 13,100 100 $131 Z $ 8,000 1,500 2,100 3,900 3,250 2,750 21,500 100 $215 Total $Direct material Direct labour Short-run variable overheads (W1) Set-up costs (W2) Expediting, scheduling costs (W3) Materials handling costs (W4) Units produced Cost per unit Workings 1 2 3 4 $3,080 ? 440 machine hours = $10,920 ? 14 production runs = $9,100 ? 14 production runs = $7,700 ? 14 production runs = Conventional costing unit cost $ 95 305 95 305 44,000 $7 per machine hour $780 per run $650 per run $550 per run ABC unit cost $ 428 512 131 215 Difference per unit $ + 333 + 207 + 36 Ã¢â¬â 90 Difference in total $ +3,330 +2,070 +3,600 Ã¢â¬â9,000 Summary Product W X Y Z (a) (b) The figures suggest that the traditional volume-based absorption costing system is flawed.It underal locates overhead costs to low-volume products (here, W and X) and over-allocates overheads to higher-volume products (here Z in particular). It underallocates overhead costs to smaller-sized products (here W and Y with just one hour of work needed per unit) and over allocates overheads to larger products (here X and particularly Z). 2. 2 ABC versus traditional costing methods Both traditional absorption costing and ABC systems adopt the two stage allocation process. 2. 2. 1 Allocation of overheads ABC establishes separate cost pools for support activities such as despatching. As the costs of these activities are assigned directly to products through cost driver rates, reapportionment of service department costs is avoided. 2. 2. Absorption of overheads The principal difference between the two systems is the way in which overheads are absorbed into products. (a) (b) Absorption costing most commonly uses two absorption bases (labour hours and/or machine hours) to charge overheads to p roducts. ABC uses many cost drivers as absorption bases (eg number of orders or despatches). Absorption rates under ABC should therefore be more closely linked to the causes of overhead costs. Part A Specialist cost and management accounting techniques ? 2a: Activity based costing 25 2. 3 Cost drivers The principal idea of ABC is to focus attention on what causes costs to increase, ie the cost drivers. a) The costs that vary with production volume, such as power costs, should be traced to products using production volume-related cost drivers, such as direct labour hours or direct machine hours. Overheads which do not vary with output but with some other activity should be traced to products using transaction-based cost drivers, such as number of production runs and number of orders received.

Figure 1 23 shows the proposed network arrangement between the nodes and their associated roles within the ZigBee network. The roles within the network are in accordance with the functionalities and requirements of each type of device as specified by the ZigBee networking standard. The PC/base station has been appointed the role of coordinator since its functions include hosting the SLAM and GUI processes. Therefore the PC/base station is required to transmit GUI data commands and receive updated sensor data to and from both quadcopters. Furthermore as these processes are computationally intensive and require a lot of memory resource; the PC/ base station must be mains powered; reinforcing the requirement for it to be a coordinator. The quadcopters have been appointed the role of routers so that they are able to relay data intended for the coordinator between each other, if one of the quadcopters should fall beyond the range of the coordinator. This would not have been possible if th ey were appointed the role of end devices. The quadcopters will be battery powered although the ZigBee standard for routers recommend that they be mains powered. Nevertheless, this recommendation was made out of preventing different network segments from falling if power to the router is lost. However this is not applicable in terms of this project as the routers will not be connected to any other network segments.
