What Are The Mechanisms Of Ozone Depletion Environmental Sciences Essay

What Are The Mechanisms Of Ozone Depletion Environmental Sciences Essay The mechanism of global warming can be described by the Greenhouse effect; by which, solar radiation enters through the Earths atmosphere and is retained, resulting in increased temperatures. Solar radiation entering the Earths atmosphere is partially absorbed by the Earths surface and partially re-radiated back into space. However, having lost energy to the Earths surface, the infrared radiation is of an increased wavelength and is consequently absorbed by certain gasses (greenhouse gasses) in the Earths atmosphere. This results in the radiation being recycled within the Earths atmosphere, leading to an increased average temperature of the Earths near surface air and oceans. Ozone depletion is a result of the catalysed reactions between ozone and atomic chlorine or bromine. Chlorofluorocarbons (CFC) and bromofluorocarbons have the greatest ozone depleting potential as they form atomic chlorine and bromine upon photodissociation. Carbon dioxide, methane and nitrous oxide can be considered to have the greatest global warming potential due to their abundance. From these gasses, nitrous oxide is 310 times more effective in absorbing radiation than carbon dioxide, and methane is 21 times more effective than carbon dioxide. What is the difference between winter and summer smog? Explain the mechanism by which they are generated. Winter and summer smog can be differentiated by their constituents and thus their environmental impacts. Winter smog is made up of sulphur dioxide, partially oxidised organics and particulate matter (PM), the concentrations of which are typically increased in winter months due to increased heating from sulphur rich fossil fuels such as coal and oil. It is also referred to as reducing smog. These pollutants can affect the respiratory system and form secondary pollutants. Sulphur dioxide can form acid rain from oxidation catalysed by PM or free radicals of oxygen and nitrogen. Summer, or photochemical smog, tends to occur as a result of increased nitrogen oxides or hydrocarbon concentrations in the atmosphere due to exhausts from internal combustion engines. Nitrogen oxides can be broken down by sunlight to form radicals causing low level ozone formation, nitric acid, peroxides, aldehydes and ketones. Both types of smog are more likely to form in cities and as a result of lack of wind. The lack of air movement can result in a temperature inversion which causes a layer of still warm air to cover a layer of cool air, trapping any pollutants below the warm layer near ground level. What is the difference between stratospheric and tropospheric ozone? Explain the role of NOx in the generation of tropospheric ozone. The ozone layer typically occurs in the stratosphere and is naturally formed and decomposed from the reactions between oxygen and oxygen free radicals which are formed from the decomposition of oxygen by ultraviolet light. The stratosphere is typically located from around 20 to 50 km above the Earths surface. The occurrence of ozone at this level helps absorb harmful ultraviolet light. Tropospheric ozone refers to ozone occurring in the troposphere (up to 12 km above the Earths surface). Ozone at this level can be poisonous and also acts as a greenhouse gas with a heat trapping effectiveness of 2000 times greater than CO2. The breakdown of nitrogen dioxide by ultraviolet light can lead to the formation of oxygen free radicals. NO2 = NO + O* O* + O2 = O3 Describe the mechanisms for acid rain and eutrophication, respectively. What are the effects of these two environmental impacts? Acid rain is primarily formed from SOx and NOx. Sulphur oxides are oxidised in the presence of ultraviolet light to form sulphur trioxide gas, through reacting with water, this can then form acid rain in the form of sulphurous acid and/or sulphuric acid. Nitrogen oxides are oxidised to nitrogen dioxide which may then lead to the reaction between water and nitrogen dioxide allowing for the formation of nitric and nitrous acid. Acid rain can effect vegetation, lakes and rivers, buildings and human health. Eutrophication is the process that occurs due to excessive growth of habitats to an extent where the growth becomes destructive to the environment. Use of artificial fertilisers from farming leads to increased levels of nitrates and phosphates accumulating in lakes and rivers. The nitrates and phosphates are nutrients that increase the growth of plants and algae. When these plants and algae die they can decompose aerobically to form carbon dioxide and water. With excessive decomposition, oxygen will be depleted and anaerobic decomposition will occur, leading to formation of hydrides such as ammonia and hydrogen sulphide. More species will die due to poisoning caused by the hydrides and may eventually lead to the death of the entire habitat. Which of the above environmental impacts do nitrogen oxides contribute to? Explain how. Nitrogen oxides contribute to the formation of acid rain either in the form of nitric or nitrous acid. Upon absorbing ultraviolet light nitrogen dioxide breaks down to form nitrogen oxide and oxygen radicals. These radicals can combine with water to form hydroxyl radicals which may then react with nitrogen oxide to form nitric acid. Air pollution prevention and control What options exist for the prevention and clean-up of acid gas emissions? Emissions of nitrogen oxides can potentially lead to the formation of acid rain, with several options available for its prevention and clean-up. These primarily include selective catalytic reduction (SCR), non-selective catalytic reduction (NSCR), and selective non-catalytic reduction (SNCR). The power industry uses SCR for post-combustion NOx clean up and/or low NOx burners and SNCR for prevention of NOx formation in the combustion stage. SCR involves reacting ammonia or urea with NOx over vanadium oxide catalysts in a temperature range of 300 to 400  °C and can remove up to 95 % of NOx. SNCR involves injecting ammonia/urea in the furnace at temperatures of 900 to 1100  °C, with a removal efficiency of only around 30 %. Non-selective catalytic reduction removes NOx in a method analgous to the three-way catalytic converter used in the automotive industry. This is typically applied in the chemical industries. Sulphur oxides can also lead to acid rain. Flue gas desulphurisation (FGD) plant involves scrubbing the gasses to remove sulphur oxides. For example, limestone scrubbing is one method of FGD, which converts sulphur oxides into calcium sulphate dihydrate (gypsum). Which stages in the life cycle of an installation must be considered within the IPPC Directive? All stages of the life cycle should be considered; i.e. from cradle to grave. In order to provide an integrated approach, no stage can be left out, and a full assessment of the environmental, social and economic impacts should be carried out for the raw materials, processing, storage and transportation stages involved. Which industrial sectors are regulated by the IPPC Directive? Why do you think these sectors have been included under the IPPC Directive? The industries covered by the IPPC directive include: Energy Production Refineries Production Processing of Metals Production of Cement Lime Activities involving Asbestos Glass, Glass Fibre and other Mineral Fibre Manufacture Ceramic Production Organic Inorganic Chemical Production Fertiliser Biocide Manufacture Pharmaceutical Manufacture Explosives Manufacture Storage of Bulk Chemicals Incineration Landfill Paper Manufacture Tar Bitumen Processes Coating, Printing and Textile Activities Dye, Ink and Coating Material Manufacture Timber Activities Rubber Activities Processing of Food; and Intensive Farming. These sectors have been included under the Directive due to the requirement of controlling and limiting the environmental impact these industries can have during the manufacturing process of their relevant products. Case study: Identifying BAT for the prevention and control of NOx emissions Nitric acid manufacture What influences the yield of nitric acid? Why is it important to maximise its yield? The yield of nitric acid is effected by: The efficiency of the catalytic oxidation of ammonia to nitrogen monoxide The efficiency of the oxidation of nitrogen monoxide to nitrogen dioxide The absorption of nitrogen dioxide in water to produce nitric acid Maximising its yield allows for an efficient production; thus generating more nitric acid at the same operating costs to achieve larger profits. Maximising yield means minimising unreacted nitrogen oxide which is consequently released to atmosphere. Why are the reaction (6) and the reverse of reaction (4) undesirable in this process? The reverse of reaction 4 results in a lower NO2 yield as the reaction will tend towards the NO and O2 through a shift in equilibrium to the reactants. As the absorption of NO2 is limited by NO2 concentration, it is desirable to ensure the forward reaction in reaction 4 occurs in order to maximise HNO3 yield. In addition to this, the occurrence of a reverse reaction (4) in which NO is formed allows for the possibility of nitrous acid formation (reaction 6). Again this is undesirable as NO2 is consumed in producing an unwanted product, consequently leading to a lower NO2 concentration and lower HNO3 yields. In addition to NOx and N2O emissions, what other releases to air, water and land can be expected from nitric acid manufacture? What environmental impacts can these releases cause? Carbon dioxide emissions from burning fossil fuels for energy requirements and transportation should be accounted for, as well as ammonia, nitric acid, nitrous acid leakages. Pollution prevention and control of NOx emissions Pollution prevention: Process design and operation The efficiency of NO2 absorption to produce HNO3 can be increased further by increasing pressure. Discuss the advantages and disadvantages of pressurised systems in terms of their technical complexity, environmental impacts (including noise) and economic costs. As stated, the main advantage of a pressurised system is the improved absorption of NO2 to produce HNO3, this results in less NO2 being released to the atmosphere. However, pressurised systems require a more complex design as a result of the serious safety considerations associated with them. Failure of pressurised systems can lead to death or injury of workers on-site as well as the release of NO2 to atmosphere. Pressurised systems would require increased compression and pumping duties, contributing to increased noise pollution, operating costs and maintenance costs. The absorption column may not have been designed for higher pressures, i.e. materials of construction, column thickness, and column closures may not be suitable, and thus changes would have to be made, resulting in increased capital costs. These costs must be compared with the improved nitric acid yield in order to fully asses this option. Discuss the advantages and disadvantages of supplying pure oxygen instead of air for oxidation of NO in the HNO3 absorption tower. Address the following issues: What are the advantages of using pure oxygen instead of air in terms of oxidation efficiency, gas flowrates, column volume etc? Using pure oxygen rather than air (21% oxygen, 79% nitrogen), allows for the volumetric gas flowrate of this stream to be reduced by 79% due to the elimination of nitrogen. This results in an improved oxidation efficiency, allowing more NO2 to be formed by reducing the amount of NO. The reduced gas flowrate results in a reduced column volume, assuming a constant gas hourly space velocity. Unlike air, oxygen does not come for free it has to be produced by separating nitrogen from air (you may remember this from the last years coursework on Waste Water Treatment within the module Introduction to Sustainable Development). This is usually done in a large scale cryogenic process (separation by cooling). What are the implications of this in the context of IPPC (i.e. taking into account all life cycle stages associated with this process option)? The cryogenic separation of oxygen from air is a highly energy intensive process. The main stages of the process include compression, cooling, and distillation. From a life-cycle perspective, the raw material (air) is free; however, it is the processing stage which incurs the majority of environmental impact. Energy is required in the compression and distillation stages of the process, thus, assuming energy is obtained from fossil fuel sources, greenhouse gas emissions become a concern. Further to this, the requirement of refrigeration may have environmental impacts depending on the refrigerant used. Transportation of the oxygen to the nitric acid plant may have potential impacts; however, in comparison to the processing stage, any environmental impacts are likely to be relatively small. Therefore the production of oxygen does have an environmental impact to an extent; however, the IPPC does not apply to this industry, so due to the lack of IPPC regulation in the sector inefficiencie s or environmental concerns may indirectly effect the nitric acid manufacturing process. The key concern of using pure oxygen is the additional cost. Pollution prevention: Extended absorption Explain the idea behind extended absorption. What is the link between the number of transfer units (NTU) in the HNO3 absorption tower and the NOx emissions? Extended absorption (EA) allows for any unreacted nitrogen dioxide to be absorbed in a second tower, thus increasing nitric acid production and reducing NOx emissions. Oxygen can also be injected to oxidise any nitrogen monoxide so that it can be absorbed in the new absorption column. An increase in NTU in the HNO3 absorption tower results in lower NOx emissions. How would you calculate the required height of the absorption column to increase the HNO3 production yield and reduce the emissions of NOx from the manufacture of nitric acid? What information and data would you need to do that? (See the Appendix.) In order to calculate the required height of the absorption column, the NTU must be calculated. This requires the gas mole fraction at the top of the column (yT) and at the bottom (yB). The gradient of the operating line, R is also required, this is obtained from the equilibrium of the operating line, the molar gas flowrate, and the molar liquid flowrate per unit tower area. This value is then multiplied by the height of a transfer unit which is given by: Where G is the molar gas flowrate per unit tower area, ky is the overall mass transfer coefficient, and a is the interfacial area per unit packed volume. Height = HTU x NTU Pollution control: Absorption in sodium hydroxide IPPC requires consideration of wider impacts of an activity, which means consideration of a number of life cycle stages of a process. In the case of NOx scrubbing by sodium hydroxide, what parts of the life cycle must be included for BAT assessment? Analysing this system, explain why absorption of NOx in NaOH is unlikely to represent BAT. All stages of the life cycle must be considered for a through and exhaustive analysis of BAT assessment. The final stage of the life-cycle for the sodium hydroxide scrubbing option is a key concern. The disposal of the sodium nitrite-nitrate effluent is a key concern. If no suitable disposal or recycle method can be identified for the effluent, then along with the increased costs incurred from NaOH feedstock and increased pumping, this option does not represent BAT. Pollution control: Non-selective catalytic reduction (NSCR) Non-selective catalytic reduction (NSCR) is quite efficient in reducing the emissions of NOx from the manufacture of nitric acid. However, it also generates additional environmental impacts. Identify these impacts for hydrogen and natural gas as reducing agents, respectively, and explain the origin of these impacts. The requirement of a reducing agent such as hydrogen and natural gas has significant environmental implications. Hydrogen is likely to have been produced from steam reforming of fossil fuels, and natural gas is a fossil fuel, therefore, consideration should be given to the process of extracting the fossil fuel, transporting it and processing it. In the case of hydrogen, the processing stage is likely to be a key concern as it is an energy intensive process which results in further emissions and additional environmental impacts. For example, steam reforming of methane to produce hydrogen and carbon monoxide is an endothermic reaction requiring heat generated often from burning fossil fuels. However, using methane as a reducing agent leads to the formation of CO2 in the process. Calculate the amount of carbon dioxide in t/yr generated in the NSCR process which removes 1.5 t NO2/day from the nitric acid tail gas using natural gas. Calculate the potential for global warming from these CO2 emissions. Compare that with the global warming avoided by the removal of the equivalent amount of N2O per day from the same tail gas. What do you conclude? 2CH4 + O2 + 2NO2 +2N2O = 2CO2 + 4H2O + 3N2 Mass of NO2 = 1500 kg/day Molecular Weight of NO2 = 46.01 kg/mol Moles of NO2 = 32.60 kmol/day Moles of CO2 = (2/2) * Moles of NO2 = 32.60 kmol/day Molecular Weight of CO2 = 44.01 kg/kmol Mass of CO2 = 1.4 t CO2/day Assuming that the plant is operational for 365 days per year, the annual amount of carbon dioxide generated by the NSCR process can be estimated as 524 tonnes per year. N2O has a heat trapping effectiveness of 150 times that of CO2; thus the saving made by converting N2O to CO2 is substantial with regards to global warming potential. The N2O produced would be equivalent to 78,551 tonnes of CO2 per year. Use the example in the previous question to calculate the equivalent acidification impact that would be avoided by the removal of NOx with the NSCR process. Compare this avoided impact with global warming generated through the use of natural gas to remove the NOx. What do you conclude? How should we approach situations like these, where reducing one environmental impact causes another? The classification factor for NOx is estimated as 0.7 kg/kg. Therefore acidification savings can be estimated as 1050 kg/day which is equivalent to 383 tonnes per year. In comparison to the 524 tonnes of CO2 produced per year, it can be noted that the reduction of the acidification impact does not outweigh the CO2 produced in the process. Pollution control: Selective catalytic reduction (SCR) What are the main environmental and safety concerns associated with the selective catalytic reduction (SCR) process? SCR typically uses ammonia or urea to catalytically convert nitrogen oxides to molecular nitrogen and water; however, the production of these reactants have key environmental considerations. Ammonia production typically involves steam reforming of a hydrocarbon feedstock such as natural gas or naphtha. Thus, fossil fuel depletion and the issues surrounding fossil fuel extraction, transportation and processing are all key sustainability concerns. However, ammonia produced from naphtha would be more of a concern than ammonia produced from natural gas due to the additional refining process from which it is produced. Ammonia production also involves the emission of carbon dioxide, a greenhouse gas. Gas preheating also has an impact on energy requirements and thus greenhouse gas emissions. On-site ammonia or urea storage would be required; any leakages of ammonia could prove fatal as it is toxic upon inhalation. Catalyst disposal may also have various environmental impacts depending on the toxicity of the used catalyst. Why is it important to minimise ammonia slip from the SCR process for NOx control? The occurrence of ammonia slip results in inefficient use of feedstock. Costs can be notably reduced by ensuring minimum ammonia slip throughout operation. Ammonia may also react with other compounds to form unwanted products. For example, ammonium bisulphate formation in power industry often results in damage to air heaters. Therefore, this should be further investigated for the application of nitric acid production to ensure any unwanted compounds are not formed. Further to this, as ammonia is toxic, any ammonia slip would result in release to atmosphere; therefore potential health concerns exist. Balancing environmental and economic costs What would be your answer to the above question on the comparison between SCR and NSCR? From table 2, it is evident that SCR can provide an improved NOx removal (exit level of 100 ppm) in comparison to NSCR (205 PPM); however, SCRs failure to remove N2O may be a key concern when compared to NSCR which does remove the compound. However, unlike NSCR, SCR does not result in significant CO2 emissions. The economics of both options demonstrate that when combined with EA, NSCR is significantly more expensive than SCR and only provides an improvement of 0.3 %. Therefore SCR would be chosen over NSCR. Analyse the data shown in Tables 3 and 4 and make your own choice of BAT for NOx prevention and control. Explain and justify your choice. The significant costs of NSCR in comparison to SCR would result in increased nitric acid prices, to the extent where it would not be profitable to manufacture. The small gains in removal efficiency made using NSCR over SCR with EA do not justify the large difference in price; therefore, the choice of BAT is between EA and EA with SCR. With EA adding a cost  £ 230 per tonne of acid, and EA+SCR adding a cost of  £ 880 per tonne of acid, from an economic perspective it would be most suitable to chose EA due to its high NOx removal of 94.8 %. However, the improved removal efficiency of SCR (98.5%) does allow for an argument to be made for its choice as BAT. With regards to cost, EA+SCR does provide increased costs and lower profits; however, its ability to sufficiently meet IPPC targets cannot be overlooked, thus for this reason, it should be chosen as BAT. The social implications of the pollution prevention and control techniques have not been considered above. Can you identify them for each option? Do the social considerations change your choice of BAT? Both EA and EA+SCR share common social implications such as the construction of new plant absorption column for EA, and a reactor for SCR. This involves construction vehicles travelling through the area, resulting in increased noise pollution. Other social impacts of EA are minimal as an increased compression requirement may result in slightly increased noise pollution. If energy is generated on-site for the compressors, then higher greenhouse gas emissions may be a concern. With regards to SCR, ammonia slip is a key concern, as the gas is toxic when inhaled. Further to this, the energy required for gas pre-heating also contributes to increased greenhouse gas emissions. Overall the EA option proves more suitable in terms of reducing social impacts and so this would be the option for BAT. Choosing BAT Why do you think the company has chosen to consider these two options and not any other described above? Choosing to modify the absorption column in order to operate at higher pressures would be a lot cheaper than employing the extend absorption option which would require the construction of an additional column, thus resulting in increased capital and operational costs. In addition to this, this option would be chosen over the NaOH absorption process, again due to the increased capital costs resulting from an additional absorption tower and the increased operational costs incurred from a NaOH feed. Increasing operating pressure does not have any significant on-site environmental releases/impacts other than an increased compression duty. SCR may have been chosen due to its ease to be retrofitted and its high removal efficiency. In comparison to other options, SCR provides the best performance for NOx removal. Choosing BAT: Environmental considerations Consider the LCA results shown in Figure 5 and answer the following questions: Why do you think the SCR option has higher fossil fuel and ozone depletion than the base case? The requirement of natural gas for the production of ammonia is likely to be the primary cause of increased fossil fuel depletion for SCR. NOx formed during ammonia production may also be a cause of the increased ozone depletion associated with SCR. In addition to this, ammonia slip may result in ammonia being released to atmosphere which then reacts with ammonia to produce ammonium nitrate. The fact that SCR is better for some impacts but worse for the others when compared with the base case makes it more difficult to chose BAT. If you as a plant operator had to choose between these two options, which one would you choose? Justify your choice by discussing the significance of global impacts (such as ozone depletion and fossil fuel depletion) and regional and local impacts (such as acidification and photochemical smog). In comparison to the base case, SCR only has a slightly higher fossil fuel and ozone depletion; whereas other impacts such as acidification and human toxicity are significantly reduced through using SCR. As efficiencies are made in the ammonia production process, SCR could potentially have a reduced impact on fossil fuel depletion. In addition to this, the production of ammonia using energy from renewable sources is also an option to reduce fossil fuel depletion, as well as the ability to generate hydrogen from the electrolysis of water using renewable energy. Based purely on environmental considerations, which process out of the three options (base case, HP and SCR) would you choose as BAT? Explain why. Based only on the environmental considerations, HP demonstrates BAT. In comparison to the base case and SCR, HP has the least environmental impact for fossil fuel depletion, global warming, ozone depletion, acidification, photochemical smog, and human toxicity. Compare now the SCR and HP options in terms of the level of NOx emissions that they can achieve. Which process would you as an operator choose? Why? The HP modification has a removal efficiency of 84%, removing 1202 ppm of NOx; however, SCR has a greater removal efficiency of 93%, removing 1332 ppm of NOx. As the base case plant produces 1432 ppm of NOx per hour, the outlet concentrations for the HP and SCR modifications are 230 ppm and 100 ppm, respectively. SCRs effectiveness in removing NOx is notably greater than that of the HP option; therefore, from an operational point of view, SCR would be chosen. Combine both the environmental impacts and the levels of NOx emission that each option can achieve and make an overall choice of BAT. Justify your choice by taking into account the IPPC principles. Both options satisfy the IPPC principles to a certain extent. However, HP has greater compliance than SCR with the IPPC principles. HP and SCR both provide protection for the environment as a whole by reducing NOx emissions from the nitric acid plant. Although, SCR has improved removal efficiency over HP, the impact of ammonia production fails to demonstrate SCR as the BAT in comparison to HP in this case. HP provides a better case for pollution prevention, by reducing NOx formation throughout the process; whereas SCR demonstrates a case for pollution control. As prevention is preferred to control, HP again provides the better option. In providing a balance between the environment, economics and social impacts, HP provides the better option. Significant reductions in global warming potential, acidification and human toxicity are made through employing HP over SCR, with notable gains in reducing fossil fuel depletion, ozone depletion and photochemical smog. Although SCR demonstrates a n improved NOx removal efficiency, overall, the environmental impact as a whole can be reduced by employing HP modifications. Further to this, the income generated by HP modifications, can contribute to further plant modifications leading to improved process efficiencies. Therefore, considering its wider compliance with IPPC principles HP would be chosen as BAT. Choosing BAT: Socio-economic considerations Choose your preferred NOx prevention or control option considering the internal (MAC) and external costs (MDC) shown Tables 6 and 7. Justify your choice. With regards to the marginal abatement costs (MAC) for NOx emissions, the HP option clearly proves to be the more attractive option due to the savings made ( MAC =  £ -92 per ppm). The surplus energy generated and increase in acid produced leads to improved revenue which consequently reduces the operating cost of the plant. However, SCR increases operating cost by  £ 225 per ppm of NOx removed. In order to asses if SCRs improved removal efficiency can justify such a cost, the marginal damage cost of both options was compared. The results indicate that MDC due to NOx emissions was lower for SCR ( £ 35,770 per year) than for HP ( £ 82,320 per year). However, the MDC fails to consider environmental impacts other than NOx emissions. If costs were considered for the impacts of ammonia production, it is likely that the MDC for SCR would be much higher. Considering this, HP was chosen as the best option. Choosing BAT: The whole picture List all criteria relevant for choosing BAT in the above case study. On the basis of the results obtained, rank the three options in order of their desirability. You may wish to create a ranking table, assigning a number to each technology to indicate the order of preference on a scale from 1-3 (e.g. number 1 indicates the best option and 3 the worst); this ranking should be done for each criterion you have listed. NOx removal efficiency/Marginal Damage Costs SCR HP Base Case Marginal Abatement Costs HP Base Case SCR Life-Cycle Environmental Impacts HP SCR Base Case Compliance with IPPC Principles HP SCR Base Case Identify BAT for the conditions of this case study, assuming that you are Head of Engineering and Technology Division in a company. Justify your choice. Based on the criteria listed in question 1, HP demonstrates the most suitable option for IPPC compliance, reducing overall environmental impacts as well as providing savings in operating costs. Although SCR has a greater NOx removal efficiency, HP is consistently and in some cases significantly better than SCR in reducing environmental impacts such as fossil fuel depletion, global warming, ozone depletion, acidification, photochemical smog, and human toxicity. In addition to this, choosing HP not only reduces the plants environmental impact, but allows for improved energy generation onsite. Therefore, gains in efficiency can be made, reducing reliance on volatile energy prices. The HP option does not require additional feedstock, unlike SCRs ammonia requirement, and is therefore not as directly exposed to price fluctuations. Thus, the option of HP modification is econo

Eugene Onegin Comparison

Eugene Onegin The transformation from a novel in verse to an opera Although written in the early 1800s, Eugene Onegin, a novel in verse written by Alexander Pushkin, is still regarded as one of the most influential and beautifully written pieces of work to this day. As it shifted cultural norms, opened new discussions, gave way to new forms of writing, and introduced novel approaches that envisioned life in a different light, Eugene Onegin was revolutionary.With its central theme revolving around the conflict between dreams and reality, the novel in verse caught the attention of readers all over the world, with over thirteen translations written. As well, other artists have adapted the work and interpreted it through their own art forms, including a ballet by John Cranko in 1965, and the famous opera by Pyotr Ilyich Tchaikovsky, which opened in 1879.Tchaikovsky’s interpretation in particular gathered much success and worldwide recognition, arguably more than that of Pushkinâ⠂¬â„¢s novel. While the characters and the storyline are mainly preserved, Pushkin’s main characters – Lensky, Onegin, and Tatyana – become more multi-dimensional and relatable in Tchaikovsky’s opera. Because he was an artist in the romanticism era, Tchaikovsky adds his own inspiration to the novel when changing it to an opera, creating many noticeable distinctions between the two.Compared to the novel in verse, the operatic version of Eugene Onegin has various deviations due to Tchaikovsky’s romanticism and character bias, which include changes in the duel scene, the increased favouritism of certain characters by Tchaikovsky, and the absence of a narrator. Throughout the course of Pushkin’s novel in verse, there are four main parts of the storyline that grab the attention of the reader and create the plot. One of the four scenes is a duel between Onegin and his best friend Vladimir Lensky, after Lensky caught Onegin flirting shamelessly wit h his fiancee.This scene was considerably altered between both artworks, as there was a very strong difference in the portrayal of Onegin’s guilt in the novel and in the opera. In Pushkin’s novel Onegin is very remorseful and heartbroken after killing his best friend. The narrator notes: Deluged with instant cold, Onegin hastens to the youth, Looks, calls him†¦ vainly: He is no more. The youthful bard Has met with an untimely end! †¦ In the ache of the heart’s remorse, His hand squeezing the pistol, At Lensky Eugene looks. â€Å"well, what – he’s dead,† pronounced the neighbor [Zaretsky] Dead!†¦With this dreadful interjection Smitten, Onegin with a shudder Walks hence and calls his men. In this piece, it is evident that Onegin is deeply conflicted with the crime he had committed. Dealing with the death of his friend, Onegin leaves town to find peace of mind. In the opera, however, Tchaikovsky leaves little time for Onegin†™s mourning. In the novel, Zaretsky, a friend of Lensky who attended the duel, is the first to speak after the fight finishes. Contrary to the novel, instead of Zaretsky being the first to speak of the death, it is Onegin who brusquely asks â€Å"Is he dead? In most stagings of this opera, Onegin simply walks to Lenksy’s body as if to double-check his passing. As scholar Julia Torgovitskaya states, â€Å"Because in an opera it would be difficult to convey a considerable length of time passing [i. e. for Onegin to mourn Lensky’s death], Tchaikovsky allows the scene to end right after Lensky has fallen. † The result of this change of scene from the novel to the opera is highly profound. In Pushkin’s story, readers are able to sympathize with Onegin in understanding his regret.Readers turn to Onegin and Tatyana’s communion as the happy ending they yearn for in the face of Lenksy’s tragic death. In the opera, on the other hand, the audience b egins to demonize Onegin, and there is a negative incline and desire for Onegin and Tatyana to be together. This single scene, being different between the two art forms, changes the entire mood of the story and the attitudes the audience would have towards its characters. The changes of certain scenes also come from Tchaikovsky’s bias towards specific characters, which result in a different presentation of their personalities on stage.Tchaikovsky, being an advocate of romanticism, presents the characters of Tatyana and Lensky in a more compassionate and sensitive manner. The opera differs from the novel as certain characters are viewed in a much stronger light, and their prominence has shifted. For instance, the character of Tatyana, a young, shy but passionate woman, was highly recognized and loved by Tchaikovsky. Due to this, the letter scene, where Tatyana spends an entire night writing and confessing her love for Onegin, was more emphasized and intimate, leaving the audie nce touched by Tatyana’s courageousness.With the addition of music, this scene was the longest and most complex solo section of the opera, further establishing the deep bond Tchaikovsky had for the character of Tatyana. After working on the writing of the letter scene, Tchaikovsky wrote â€Å"Being completely immersed in composition, I so thoroughly identified myself with the image of Tatyana that she became for me like a living person, together with everything that surrounded her. I loved Tatyana, and was furiously indignant with Onegin who seemed to me a cold, heartless fop. † With this magnetism, there was a shift in directive depiction between the main characters.It is important to note that in this opera, much of Pushkin’s text is cut out due to length (for it takes longer to sing a verse than utter written words or phrases), but the scenes with Tatyana and Lensky remained largely unchanged. For example, the night before the duel, Lensky writes to his wife a love letter pouring his heart out, knowing he is to die the next day. In the opera, Tchaikovsky has Lensky sing the contents of this letter in a heartfelt aria. Although it is very moving and beautiful, it is very far from Pushkin’s character of Lensky.In Pushkin’s work, instead of praising Lensky for his poetic nature and optimism, the narrator indicates that his romantic idealism stands as the result of his lack of world experience and naivete: He did his best to hold back the cynical comments that came to his lips, reflecting to himself, ‘It’s stupid for me to spoil his momentary bliss – it’ll vanish soon enough without my help. Meanwhile let him live on the belief that the world’s a perfect place. Youth is a kind of fever, and we must forgive the young their fire and their delirium.Although the narrator in Pushkin’s novel ridiculed this youthful euphoria, Tchaikovsky encourages and emphasizes the tenderness radiating from Lenksy. Thus, there is a considerable amount of romanticism added to both plot and character in Tchaikovsky’s opera in comparison to Pushkin’s novel. Finally, the most controversial deviation of the opera from the novel in verse is the absence of a narrator. This results in a critical difference between the two art forms, as the narrator’s input, digressions and lessons are not present in the opera, thereby changing the story’s defining attributes.In the novel, the narrator serves many roles, one being a voice of sarcasm and ridicule towards the characters, showing them the irony in which they live their lives. When reading the novel, readers were unsure of whether to be sympathetic to some characters, for it was possible that the narrator would interrupt with sarcasm or mockery revealing that the characters were undeserving of compassion. In the opera, the role of the narrator is removed, resulting in a more straightforward version of Pushkin’s ta le, where the characters clearly either deserve sympathy in their troubles or do not.In the novel, there was no need for characters to introduce themselves, due to the presence of a narrator, but in the opera, there are characters that have to introduce themselves to the audience. This happens, for instance, in the dueling scene (scene 5) where Zaretsky introduces himself: I am a pedant where the class duel is concerned, And I am naturally methodical. I do not allow a man to be stretched out Any old way†¦ In this scene, Zaretsky has to speak of himself to Onegin before the duel, explaining who he is and why he is there.This is completely different from the novel, where the narrator explains everything without awkward dialogue: Zaretsky, once a reprobate, Gambler-in-chief, an intimate And sage of inns, a philanderer; Kind and sober, now, instead, Father of many, still unwed†¦ Many scholars, such as Richard Taruskin, argue that in this opera, â€Å"the music, quite simply, is the narrator. From the very first sung notes†¦ the music acts as a very busy and detached mediator of situations and feelings. † This can be seen through the different musical pieces that play for each character, which in turn contribute to the audience’s interpretation of the character.For instance, Tatyana received the most colourful and lyrically driven music, while Onegin sings less memorable lines with simpler orchestral accompaniment. Although, one should note that the musical accompaniment of the characters’ actions are also biased, as the music that plays is the music that reflects how Tchaikovsky views them. Tchaikovsky, in one way, creates a new narrator by deciding how the characters will appeal to the audience, using music as his tool. For example, Tchaikovsky views Onegin as incapable of having genuine feelings, and so the music attributed to him is less inspired than that attributed to Lensky.In addition, the narrator in Pushkin’s nov el constantly interrupts the progression of the novel, which creates a storyline where two things occur simultaneously. In the opera this effect is achieved in a less destructive manner, because as novelists must arrange things in a sequential order, â€Å"musicians can simultaneously present and comment without recourse to digression. † When an event or conversation is happening on its own, it can be accompanied by music that tells a different story; consequently, two conversations can take place at the same time.The music plays, in this way, a role similar to a narrator, as it feeds information to the reader as events unfold, and gives insight on the situations through melodic remedies. Therefore, in the transition from novel in verse to opera, Tchaikovsky dropped the character of the narrator, and used music as a tool of explaining the story. In conclusion, the conversion of Eugene Onegin from a novel in verse to an opera includes many various deviations from the overall p lot and character emphasis in the story. With Tchaikovsky’s affinity and bond with the characters of Tatyana and Lensky, he portrays Onegin as demonic and insignificant.With this affinity, he manipulates the original storyline with romanticism to fool the audience into sympathizing with Tatyana and Lensky, whereas Pushkin’s narrator is notorious for ridiculed them. Furthermore, Tchaikovsky takes advantage of the absence of a narrator, and uses music’s capacity for emotional influence to further implement his bias for Tatyana, Lensky and Onegin. The narrator in Pushkin’s novel serves as a source of information to provide the readers with context concerning the setting, characters and story line where as Tchaikovsky uses character dialogue to provide such information.Overall the changes between Pushkin’s Eugene Onegin and Tchaikovsky’s operatic telling of the story were controversial but allowed for two different expressions of the same story. These deviations can be attributed to Tchaikovsky’s affinity for romanticism and his preference for Tatyanna and Lensky in comparison to his strong dislike for Onegin. Nevertheless, both versions of Eugene Onegin are still regarded as powerful pieces of artwork. Despite their differences, however, both tales leaves their audiences craving for answers to their questions: what happens next? Bibliography Brown, David.Tchaikovsky, The Crisis Years, W.

Schizophreni A Complex Psychological Disorder - 990 Words

The word schizophrenia means split mind and was first used in 1911 by Eugen Bleuler. According to Paul Eugen Bleuler and the origin of the term schizophrenia as the disease becomes distinct, the personality loses it unity. Originally it was meant to describe patients whose thoughts and emotions seemed disconnected or disrupted. Unlike the meaning of the word schizophrenia, it has nothing to do with split personalities. Schizophrenia is a complex psychological disorder that can be characterized into 4 different categories; paranoid-type, disorganized-type, undifferentiated-type, and residual-type. All 4 types of schizophrenia have their own symptoms and treatment. According to Melissa K. Spearing from an Overview of Schizophrenia, paranoid-type schizophrenia is commonly characterized by delusions and hallucinations. A delusion is when an individual believes that there are conspiracies or other plots against them. Often the thoughts of conspiracy come to them in auditory or visual hallucinations. These mistaken beliefs can include love ones, and often the sufferer of paranoid-type schizophrenia will go to extreme lengths to protect themselves and others. Without proper treatment protective behaviors can stretch as far as homicide and suicide. Once someone with paranoid-type schizophrenia convinces themselves that they are being conspired against, it is hard for anyone to get them to see otherwise. Treatment for this condition includes antipsychotic medications.

Cuba s Modernization During The 20th Century - 1697 Words

Cuba’s Modernization Current events in Cuba have caught a lot of attention, as we witness a historical shift in their opinion of true trade in a communist based society. Fidel Castro has been dealing with the U.S. since the 1960’s in various ways. Now that his brother Raul will take over control, boarders and opening and travel cruises have begun! To show this transition of communism to capitalism you must have some background knowledge. Communism is, â€Å"A way of organizing a society in which the government owns the things that are used to make and transport products (such as land, oil, factories, ships, etc.) and there is no privately owned property.† - Merriam Webster dictionary. The idea of communism originates from Marxism, founded by Karl Marx, a German philosopher. Marx believed that wealth should be evenly distributed among the people. During the Industrial Revolution he saw factory workers working long hours in harsh conditions struggling to get by, while capitalist we’re getting rolling in the money. He believed in taking the factories and stores from capitalists and handing them over to the workers/ producer, initially this would eliminate surplus value. This would increase production and involve all members of society to unify the communities. His goal was to influence the government in taking over these corporations and create an equal society with no social classes and â€Å"Every one having the same†.

The Legalization Of Physician Assisted Suicide - 1720 Words

It is obvious discussing physician-assisted suicide is a very controversial issue that is discussed daily by those who wish to die to avoid loss of dignity and also by those who think it is unethical. For physician-assisted suicide to even be considered, the patient must be of sound mind when they are requesting death with dignity. Physician-assisted suicide should be a legal option for people who are unable to end their own lives. However, there should be safeguards to prevent any sort of abuse. There should be the legalization of physician-assisted suicide, but not for active euthanasia. â€Å"It should never be contemplated as a substitute for comprehensive comfort care or for working with patients to resolve the physical, personal, and social challenges posed by the process of dying† (Meier, D.E., p. 294). If an incurable patient who is suffering asks for specific help in physician-assisted suicide, physicians should have the obligation to fully scrutinize the request. Not only is it the seriousness of considering medicine as the placement of certain suicide an issue, it is a form of direct killing. Medical advances are surely making it easier to reduce pain and suffering, so why should there be policies devised and sanctioned by the state to kill those in pain and suffering?

Adult Learning Techniques and Methods Application for successful Free Essays

string(57) " Mezirow and Freire on their take on effective learning\." Many organizations in today’s competitive business world focus on training to enhance capacity development to their staff in order to compete effectively. The reason that underlies this competition is the emergence of knowledge based economy that put organizations to task and compete on the basis of knowledge. Therefore, many companies focus on building and equipping their staff with necessary skills and knowledge. We will write a custom essay sample on Adult Learning Techniques and Methods Application for successful or any similar topic only for you Order Now It is therefore, a daunting task to design, develop and plan for the workforce training intervention; since are different from children in regard to learning. As a result of complexity in instructional approach for adult learning, many training intervention for the Human Resource Development programs fail to give the desired results or changes intended by training intervention. The area of approach to design of training intervention is an outstanding concern because it determines the outcome of those training programs. In this regard, this paper shall look at best training or learning design to be embraced while developing a training intervention for developing workforce. This is because adult learners process information differently than one another and justify special approach. Introduction Organizational learning usually aims at capacity development of the organization, individual and occupational. Campbell (2007), defines organizational capacity as the organizational potential to perform that is enabled by its ability to define and realize its goals and objectives in a more sustainable and relevant manner. Therefore, organization capacity development shall refer to the processes by which an organization effectively formulate and achieve organizational goals. In order to achieve the desired Organizational capacity through learning, training should focus to realize the needs and goals of the organization. Capacities emphasized in organizational learning are: adaptive capacity that enables organization to learn and change in response to operational environment dynamism; and operational that aims at equipping the organization workforce up-dated skills and knowledge to carryout daily activities of the organization (Baud, Gerick 1999, 131). Powers (2002), states that in order for the organizational learning to bear fruit and be meaningful, process of learning should be emphasized to ensure quality instruction to the adults in learning session. A quote by Campbell, (2007), says â€Å"many organizational facilitators have failed to give quality instruction to learners during organization’s workshops, seminars and trainings because their content and methodological approach do not match the needs of the learners† Therefore, in order to have a meaningful and useful training. A variety of learning techniques and methods are necessary when training and developing adult learners because adult learners process information differently than one another. In this line of thought, the paper shall look at these techniques that should be employed to carter for adult differences in processing the information. Learning objectives Learning objectives are important because they guide the instructor on the designing, planning and developing training that is relevant to the needs of the trainees in relation to agenda of meeting the organizational goal. Taylor (2003); notes that good learning objectives should be derived from need assessment conducted. Importantly, learning objectives should be; realistic, measurable, time conscious, and take into account the needs of the learner. Using two sets of objectives: general objective depicts changes or competencies expected after training; while the specific objective describes what the trainees should be able to do after undergoing the training, the instructor should formulate content, method and aids to be used (Kraiger, Salas, 1997, p. 272). Organizational learning In order to have a successful and relevant Organizational training should involve identification of the target group; learning mode choice; and selection and sequencing of the contents. Identification of the training target group: training intervention will be rendered fruitless if the trainees do not put into practice the training when they go back to their functions resulting from wrong choice of the participants (Baud, Geric, 1999, p. 95). Therefore correct participant’s choice is necessary. For example, in some cases the entire department may be selected for training where there are changes in the processes regarding to that department. While in other cases, key person is involved for training for specific task or skills like C.E.O. or manager Training mode choice: it’s important to consider sheer volume and learning task complexity that can be used to direct the choice for distance or onsite classroom. While mass vs. distributed training, since research indicates that training instruction under distributed practice is retained more and longer. Selection and sequencing of the content: the content should be strictly based on the learning objectives in consideration with job and task analysis. The difficult task should be allocated appropriate and sufficient time. Additionally, learning topic should not come in ad-hoc manner since it may hamper learning. Rest duration is important and dependant on the memory warm-up and psychological fatigue. In relation to rest duration, Armmons (1947), research work indicated that performance efficient may rise between 18%-43% with rest duration of 5-20 minutes after an intensive learning by trainers (Baud, Gerick 1999, p. 294). Training Activities, techniques and methods This is central to learning by using of instruction strategy and approach. According to Kraiger and Salas (1997), instructional strategies are set of tools, contents and methodologies which are combined to create an instructional approach. In this connection four best principles should be used to create an efficient instructional strategy: relevancy of concepts to be learned, demonstration of the altitudes, knowledge and skills to be learnt by learners; and feedback provision to instructors after practice and during practicing the skills attained. The instructional strategy selection is dependant on the instructor, but should choose a variety of strategies to accommodate content delivery, objectives, materials or aids used, and aim to maintain interest of learning.   Adults learns best by doing and working in a non-threatening, participators, respectful and informal environment. Principles of adult learning useful for instruction design In regard to performance improvement through learning, there are six key principles to enhance successful adult learning. These principles integrate the perspectives, models and theories provided by great scholars like Kolb, Knowles, Mezirow and Freire on their take on effective learning. You read "Adult Learning Techniques and Methods Application for successful" in category "Learning" Participation: In learning, trainees learn more and remember the content of the subject matter when they are actively engaged in learning process. While skills best develop by doing and engaging in practical exercise, group work, simulation, games and discussion. Furthermore participation can be enhanced by facilitating a collaborative environment, role sharing and use of friendly dialogue to encourage sharing of experiences and knowledge. Thus by enhancing positive altitudes and learning atmosphere it corresponds to participation boosting to trainers. Understanding: Greater understanding can be enhanced when training starts at the level of the trainee as provided by training needs assessment. Practices and learning activities that can increase understanding to trainers are appropriate use of vocabulary according to trainers level, use of trainers language, avoidance of unnecessary technical jargon (Celinski, 1983), reformulation of ideas in trainers own words, use of real life examples provided by the trainer and use of learners experience as examples. The checking mechanism for the learners understanding is through use of short questions. Feedback: Feedbacks are important part of construct process for learning. Through feedback the trainees get a sense of their progression towards learning objectives and if not, they strategize how to get there. Feedback should be provided shortly after instruction to enable learners relate to processes they have used. Additionally, learners should be given good reacceptance on their feedback to encourage them to try again. For instance, instructor should use encouraging term like good trail or good attempt even if the trainee has given a wrong feedback. Interest: In training intervention, learner’s interest comes as a result of learner’s intrinsic motivation. Whereby, the trainee should be made to feel the need to learn and own the goal of training is likely to increase urge to participate and be more engaged. To achieve trainees interest in training intervention, learning objectives must be relevant to their needs, Kolb (1979) emphasize that adult learners interest is embedded in their personal histories, vision of who they are and what the want to do. Therefore, to capture the interest of trainees, learning methods should integrate work and studies, theory and practice will provide a more productive learning undertaking by the workforce. In addition to this, adult will only remember or have interest to learn what they consider useful to them and has pleasure to learn it. Therefore, learning should be cantered on the content relevancy in accordance to what adult’s value with more pragmatic examples like marriage, divorce, parenting, taking a new job, losing a job (Powers, 2002, p. 241). Emphasis: Emphasis is attained by focusing the attention of learners on the most important points that will be useful to make a trainee remember easily. This emphasis should be used to crucial points. Through instructors, repetition, reformulation, examples, summarizing or asking question gives emphasis to main ideas desired to be attained by use of didactic aids and exercises. This by giving more attention and time to certain concepts, it allows learners to practice and retain skills and knowledge. (Baldwin, Ford 1998: 217), state that when a trainee is not able to recall content after a training session, the content is likely to have extend the long term memory, as a result it will not be retained. Results: Organizational training intervention aimed at capacity development should make learners feel successful after the training session and enable the employee to plan how to effect and use the skills and knowledge attained in organizational working environment. As a result this learner’s confidences in his or her ability to cope with work task to a great extend supports performance improving to an individual and organization collectively. The instructor can scaffold the trainees by keeping them informed on their progress, congratulating for good work and more accelerated by issuance of a participatory certificate to the trainees, the certificate will put employee in task of reflecting the theoretical value of certificate to practical world (Baud, Geric, 1999, p.103). Teaching methods and techniques The instructional methods designated to have a positive impact to an adult learner, should aim at fulfilling the special characteristics of the adult learner. These characteristics are geared towards achievement of LEARN (Leadership, Experience, Appeal, Respect and Novel Styles) that makes them realize their need to gain something; to be something; to do something; and to save something in an event of learning (Goldstein, 2003, p. 219). The following general techniques are proposed. Icebreaker: good and integrated introduction to achieve a friendly and a relaxed atmosphere in a learning session. Done through adjourning the learning for five minutes and for each member to introduce himself to the person on his right by giving name, where he comes from, hobbies, and interests. Researchers have found out that icebreaker breaks down the formality of meetings that tends to force shy members into deeper silence. Group Discussion: it is evident that people enjoy learning, themselves more when are engaged in discussion groups and can remember well the information discussed in the group. The advantage to the instructor is that he or she has a quicker way to obtain the views of all members. The learners shall have the opportunity to participate in the discussion. Furthermore, learners consider that they are contributing to the goal of progress and that their contribution is being recognized. Brainstorming: This is a technique used by the instructor to literally storm a problem to achieve the maximum number of ideas in the shortest possible. The purpose of brainstorming is to stimulate the creative ability of the trainees and improves creative powers. Case Study: employing case studies that describes a situation that contains a number of problems and it requires a solution. This gives the trainees a basis and opportunity for studying a situation, analyzing its important aspects, and reaching various conclusions. Team presentations: the importance of team presentation is to create a sense of team building and provides an ideal learning and review experience. As a result, the learners shall be able to understand the issue and convey it in a creative and entertaining Learning games: this is an activity that is meant to complement the learning experience. Inclusion of a game into a training module allows the trainer to drive home a point in another fashion, thereby increasing the probability of retention and application. Ideally, content retention of new material or a new skill will be more likely if the trainee hears it more than once or practices new behavior several times (Goldstein, 2003, p. 229). Conclusion To sum up the paper, the paper has discussed and examined the best practices that can facilitate effective adult learning in the context of organizational learning.

Getting Started in Small Business for Dummies

Question: Discuss about the Getting Started in Small Business for Dummies. Answer: Introduction The activities such as data collection, recording the transactions in the books, and preparation of the financial statements were used to be done manually when the automated accounting systems were not developed. With the increased business complexities, it was perceived difficult to maintain the accounting records manually and thus, the automated accounting systems were developed (Gelinas, Dull, Wheeler, 2014). Today, there are many accounting software programs being developed, among them MYOB is the one that is popular all around the world. MYOB provides solution to the problems of manual accounting system by automating the business processes such as accounting, financial reporting, and human resource functions. MYOB helps in integrated the core business function and make them work on real time basis (Curtis, 2012). In this context, the report presented here focuses on identifying the problems with the manual system being used by I SEE Company and provides solution to those problem s. Summary Table: Difficulties/Inefficiencies in Manual System and Benefits of MYOB S. No. Before MYOB (Manual System) Difficulties/Inefficiencies Benefits of MYOB 1. The booking process was time consuming Booking process became speedy (MYOB, 2017). 2. The calculations were prone to mistakes The calculations became accurate (MYOB, 2017). 3. The integration between different departments such as accounting and sales was missing or ineffective The integration between different departments such as sales, HR, and accounting became effective (MYOB, 2017). 4. The financial information could not be extracted on a real time basis The extraction of financial information became on a real time basis (MYOB, 2017). Economic Transactions in Small Business The small business would have simple economic transitions related to purchase and sales of goods and assets like office, furniture, and store items etc. Further, the economic transactions related to expense payments such as rent, salary, and utility bills will also be there in the small business. The complex transactions related to financial instruments might not be there in the small business. However, the simple economic transactions also become complex when the volume of transactions increases. With the increase in the size of business, the volume of transactions increases which makes the accounting and booking process complex appealing for automation of the processes (Taylor, 2003). In the current case of I SEE Company, there were not much problems when the company was operating with one store. However, as soon as, the company expanded business by opening three new stores, the problems in handing the business affairs started creeping in. Benefits of Using an Online Accounting Software Tool Implementing the use of online accounting software tool helps in automating the essential functions and business processes of a firm. The business processes related to bookkeeping, financial reporting, sales and marketing, human resource and administration are automated by implementing the use of online accounting software. The automation of the business processes is advantageous as it leads to speedy and accurate working (Siddiqui, 2011). The activities such as invoicing, journalizing the transitions, preparing income statement and balance sheet, budget forecasts, costing estimations, all become effective and less time consuming. Further, the overall managerial decision making process is also improved with the use of online accounting software. The information needs of the management can be accomplished on a real time basis in an effective manner through the use of online accounting software (Siddiqui, 2011). Problems Faced by Lydia and Sam in manual Accounting System Lydia and Sam manages a business of small sized business in the name of I SEE Company. I SEE engages in the business of purchase and sale of eyewear and eye care products. The company was running its business through one store till now, but looking at the increased demand, it has expanded by owning three more stores in the local area. The problem in front of Lydia and Sam is that they use manual accounting system and due to increase in business volume, it is proving to be inefficient and ineffective. With the use of manual accounting system, Lydia and Sam are not able to record the financial transactions on time basis. Further, they are also facing problems of inaccuracy in their work of transaction recording. Apart from this, the accounting records of each store are maintained separately leading to additional work of consolidation. Further, there is no integration of the accounting and bookkeeping processes with the other business processes such as stock maintenance, sales and marke ting. This is leading to delay in information extraction for different purposes like placing purchase orders and stock levels. Due to non availability of timely information, the problems are encountered in maintaining the stock levels in the cost effective manner. Use of MYOB in Recording Economic Transactions MYOB accounting system provides customer friendly solution to the bookkeeping and financial reporting related problems. In particular MYOB is considered to be the most useful accounting software for the small and medium sized business (MYOB, 2017). The accounting process in manual system is very time consuming because it involves many steps to be carried out manually. However, the company can use MYOB accounting software to perform multiple tasks at one time. The use of MYOB is demonstrated in the following three economic transactions to be undertaken by I SEE Company: Economic Transaction-1: Purchase of Material The company purchase material from the suppliers, which requires journal entry to record purchase and then posting the transaction to the purchase ledger, supplier ledger, and stock ledger. The company can perform the task of journal entry and posting to ledgers simultaneously by using MYOB. The accountant needs to enter the journal entry only and rest of the work i.e. posting to ledgers, updating the control accounts, trial balance, income statement, and balance sheet will automatically be done. Further, the stock balance would also be updated (MYOB, 2010). At the time of sale of goods, MYOB first can be used in preparing the invoice. Then after that journal entry to debit the customer account and credit the sales account would be made using accounting codes in MYOB. Further, the rest of tasks such as posting to ledgers and control accounts, update in trial balance, income statement, and balance sheet would automatically be made. Further, MYOB will also update the stock account (MYOB, 2010). The calculation of payroll can be done automatically in MYOB by putting the basic data such as wages rates and hour worked etc. Further, payroll taxes would also get adjusted using MYOB (MYOB, 2010). Limitations or Risks in Implementing MYOB First of all implementing MYOB in I SEE would be a challenging task because it would bring changes in the processes within the company. Generally, employees are found resist to change, thus, managing that change adequately and persuading the employees to adopt the changes would the biggest challenge. Further, the company would be required to arrange IT infrastructure to implement MYOB because till now they are working with manual system (Fick and Sprague, 2013). Arranging the IT hardware and software resources would also be a challenging task for the management of the company. Further, there are certain limitations of MYOB that the company will have to face as listed below: Skilled and trained Staff is required to operate MYOB. MYOB increases the cost of the company that may reduce the profits initially (Youraccountant, 2017). MYOB is suitable to the small and medium sized businesses only. As the size of business enhances the utility of MYOB decreases. It is the fact that advent of the information technology has brought significant positive changes in every sphere of life, but at the same time, it has also given rise many risks. Using the automated accounting systems is advantageous to the business in many ways, but it exposes the business to the risk of data theft and manipulations (Anthony, 2007). Thus, there exists a risk of information loss if the computerized information system is used for accounting and maintaining records. The Company I SEE will be required to have in place stringent mechanism to prevent the data from unauthorized access. Further, the risk of manipulations in the books of accounts has also increased due to the use of computerized accounting environment. It is easier to change the data in the computer systems as compared to the manual system, thus, it increases the risk of manipulations in the financial statements (Anthony, 2007). Conclusion The discussion in this report revolves around the use of computerized accounting systems over the manual accounting systems. From the discussion, it can be observed that the manual accounting system creates many problems when the size of business increases. The increase in the size of business increases the complexities in accounting processes. Thus, switching to the computerized accounting systems is necessary to make the processes effective and efficient. There are many advantages of using computer based accounting system like MYOB. The bookkeeping and financial reporting process becomes speedier and accurate that increases the employees efficiency. However, the organization has to face challenges in implementing the computer based accounting system such as managing the change and cost effectiveness. Further, there will be requirement to protect the data from unauthorized access. References Anthony. 2007. Accounting - Text Cases 12E. Tata McGraw-Hill Education. Curtis, V. 2012.
