Differences Between Christianity And Buddhism - 1636 Words

Faith Diversity Introduction Worldview can be described as how a person bases their foundation of how they live, move and have being, it can be ever changing depending on the circumstance or situation (Shelly Miller, 2006). The way a person develops their worldview can depend on many factors, one major factor can be an individual’s faith, and the philosophies of that faith. There will be two faiths that will be discussed in this paper; Christianity and Buddhism will be the faiths in focus along with the effects on the concept of worldview. Common Components and Health Care Christianity. â€Å"For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him† Colossians 1:16 (King James Bible Online). Christianity is a monotheistic religion, meaning there is only one God. God is the creator of the universe, all-powerful, all-knowing, all-present, and all-good (ReligionFacts, 2015). Christians believe that God is actually three persons: the Father, the Son, Jesus Christ, and the Holy Spirit, however the doctrine, called the trinity, argues that Jesus Christ wasn’t actually God (ReligionFacts, 2015). It is the belief that God is only attainable by following the teachings of Jesus Christ, whom was sent to earth to teach from God’s commands, therefore the way to God is through Jesus and his teachings, the Bible.

The Salah One of the 5 Pilars of Islam - 829 Words

Ritual Analysis The Salah is one of the 5 Pillars of Islam, signifying it as a key element of Islam. It is practiced throughout the Muslim world in various contexts (alone, in a group, various countries). The Salah is a very ridged and structured ritual that Muslims do multiple times a day. The Salah is a vital ritual in Islam; the layers of meaning that I will be discussing are integrating worship into daily life, submission to God, establishing a community of followers, and finally the implications Salah has when practiced in foreign environments where people are less familiar with the ritual. As the Salah is performed 5 times a day, it effectively incorporates God and prayer into the daily lives of practicing Muslims by requiring them to worship and reflect upon God as their creator and judge. Apart from the frequency of prayer, the Wudu, required cleaning of one’s self before the Salah, further reinforces the importance of not only the ritual, but of God as well (Masjid). Muslims regard this divine interaction with so much reverence that they ensure their bodies are physically clean before showing their devotion to God. This intense connection between a Muslim and God is repeated to ensure that every part of their lives is holy and mindful of God. Salah is a disassociation from daily, profane activities to stand in front of God (Religion of Islam ). With this, one may also reflect upon the nature of God as supreme creator and judge.

Optisystem package is used as the simulation tools for the whole undertaking. Optisystem package is based on realistic mold of fiber ocular communications systems and serves a broad scope of applications, therefore it is an ideal simulation tools for this undertaking.

Problem Statement Optical amplifiers have become a necessary constituent in long-haul fibre ocular systems due to the demand for longer transmittal lengths. The effects of scattering and fading can be minimized in long-haul optical systems due to the innovation of Semiconductor optical amplifiers ( SOAs ) , Erbium Doped Fiber Amplifiers ( EDFAs ) , and Raman optical amplifiers. One of the defects of EDFAs is their non flat-gain features across a given optical spectrum. In peculiar, the addition degree is well less at the terminal of the L-band between about 1600 nanometer and 1620 nanometer. Fortunately, the addition degree of such amplifiers can be rendered well level across the L-band window by the usage of addition flattening filters which are optically coupled between the spirals of Er doped fibre. However, the usage of such filters consequences in a higher noise figure in the channels holding wavelengths in the 1600-1620 nanometer scope. The well higher noise figure in the 1600-1620 nanometer scope lowers the useable bandwidth available from such EDFA amplifiers. Raman amplifiers similarly have non-flat addition features. A typical Raman addition degree curve has minimal additions at about 1570 nanometer, 1595 nanometer, and 1620 nanometer, and upper limits at 1585 nanometer and 1610 nanometer. A addition flattening filter can be applied to cut down this fluctuation but will merely be optimized at a individual operating addition value. Additionally, there is the desire to minimise the figure of addition blandishing filters in the system and the loss they incur. Clearly, there is a demand to cut down the maximal Noise Figure in EDFA addition, every bit good as to further flatten the addition curve in Raman-type amplifiers in order to cut down signal losingss throughout the web.

Chapter 2 LITERATURE REVIEW 2.1 Optical Amplifiers Optical amplifiers have become a necessary constituent in long-haul fibre ocular systems due to the demand for longer transmittal lengths. The effects of scattering and fading can be minimized in long-haul optical systems due to the innovation of Semiconductor optical amplifiers ( SOAs ) , Erbium Doped Fiber Amplifiers ( EDFAs ) , and Raman optical amplifiers. Optical Amplifier has three applications: Supporter In-line Pre-Amplifier The transmittal side of the nexus is operated by a supporter amplifier, having a high input power, medium optical addition, and high end product power. The supporters are designed to magnify aggregative optical input power to make extension. The center of an optical nexus is operated by an inline amplifier. It acts as a medium to moo input power, high end product power, high optical addition, and a low Noise Figure. It is designed for optical elaboration on the chief optical nexus between two web nodes. The having terminal of an optical nexus is operated by a pre-amplifier. It functions as a medium to moo input power, medium end product power, and medium addition. Pre-amplifiers are besides designed for optical elaboration to counterbalance for the losingss in a demultiplexer located near the optical receiving system. 2.1.1 Semiconductor Optical Amplifiers Semiconductor optical amplifiers ( SOAs ) really are laser rectifying tubes, with fibre attached to both terminals and do non hold terminal mirrors. The optical signal can comes from either side of the fibre, amplified by the semiconducting material optical amplifiers ( SOAs ) , and the signal comes out from the 2nd fibre. They are typically made in little bundle, and work for 1310 nanometer and 1550nm systems. Besides, the decreased size of the SOAs makes it an advantage over regenerators of EDFAs by conveying bidirectional. However, the disadvantage of SOAs includes polarisation dependance, high-coupling loss, and a higher noise figure. Figure 1 demonstrates the rudimentss of a semiconducting material optical amplifier. [ 1 ] Semiconductor Optical Amplifier Figure 2.1: Semiconductor Optical Amplifier [ 1 ] 2.1.2 Erbium Doped Fiber Amplifier ( EDFA ) Erbium Doped Fiber Amplifier ( EDFA ) is an optical amplifier that uses an optical fibre as a addition medium to magnify an optical signal. Rare-earth component Er ions Er3+ dope the nucleus of the optical fibre. There are three possible results for the signal photon, if a optical maser signal with a wavelength between 1520 and 1570 nanometer, and a 974 pump optical maser are fed into an erbium-doped fibre at the same time, as shown in Figure 2.2. Figure 2.2: Simplified energy degree of Er3+ ions in Erbium-doped fiber [ 2 ] stimulated soaking up: signal photon excites an erbium ion from the province E1 to a higher degree E2 and go annihilated in the procedure stimulated emanation: signal photon stimulates an Er ion at province E2 to disintegrate to E1, bring forthing another indistinguishable photon. Thus the signal is amplified. signal photon can propagate unaffected through the fibre. In the mean while, self-generated emanation ever occurs between degree E2 and degree E1. The population inversion os achieved between the energy degree E2 and E1 of erbium-doped fibre when pump optical maser power is high plenty. Thus, the input laser signal passing through the fibre is so amplified. The erbium-doped fibre and pump optical maser can be used to build an optical amplifier, viz. erbium-doped fibre amplifier ( EDFA ) .Pump optical maser could besides magnify the self-generated emanation. Therefore, ASE is ever present in EDFA, and it ‘s the chief beginning of noise in these amplifiers. [ 2 ] Advantages of EDFA are as follows: It provides high power transportation efficiency from pump to signal power. Large addition. It is polarization-insensitive. High end product power. No matching loss to the transmittal fibre. A individual EDFA can supply addition for multiple wavelengths at the same time. The disadvantages of EDFA are Derive holding wavelength dependence. The difference addition will be obtained when usage with wavelength division multiplexing. Particular fibre design. Presence of amplified self-generated emanation ( ASE ) . [ 3 ] 2.1.3 Raman Optical Amplifier The Raman optical amplifier consists of a length of addition fibre combine with a pump assembly. The pump assembly contains a brace of pump optical maser rectifying tubes. The end product of a brace of orthogonally polarized pump-diode optical masers offers backward-propagating pump power in the transmittal fibre. Due to the higher-energy ( shorter wavelength ) pump photons scatter off the quiver manners of the optical fibre ‘s lattice matrix and coherently add to lower-energy ( longer wavelength ) signal photons, forward-propagating signals achieve addition in the fibre. There are two types of Raman amplifier: distributed and distinct Raman amplifier. A distributed Raman amplifier is one in which the transmittal fibre is utilized as the addition medium by multiplexing a pump wavelength with signal wavelength, while a distinct Raman amplifier use a dedicated, shorter length of extremely nonlinear fibre to supply elaboration. The advantages of Raman amplifier are: Ultrawide bandwidth elaboration. Low noise. No particular fibre is required. Suppressed nonlinearities public presentation in transmittal systems. [ 4 ] The disadvantages of Raman Amplifier are: Relatively high pump power required. Double Rayleigh sprinkling noise and nonlinear effects when the addition of RA is increased. 2.1.4 Hybrid Raman and Erbium-Doped Fiber Amplifier ( HFAs ) Hybrid Raman and Erbium Doped Fiber Amplifiers ( HFAs ) is a combination of Raman optical amplifier and Erbium Doped fiber amplifier. So, in order to understand HFAs, the feature of Raman optical amplifier and Erbium Doped fiber amplifier is study individually. The characteristic that is being study include operation, advantage and disadvantage of the amplifiers as discuss in the paragraph above. The constellation of intercrossed Raman and Erbium Doped Fiber Amplifiers is assuring for high capacity WDM transmittal. The amplifiers yield high-gain, low noise, and high end product power that via media for long distance transmittal. [ 5 ] Figure 2.3: Experimental constellations for the three types of individual pump, intercrossed Raman and Erbium Doped Fiber Amplifier ( HFAs ) [ 6 ] Figure 2.3 shows assorted constellations of single-pump dispersion-compensating Hybrid Raman and Erbium Doped Fiber Amplifier ( HFAs ) . Type I: Hybrid Raman and Erbium Doped Fiber Amplifier ( HFAs ) recycling residuary Raman pump in a cascaded EDF subdivision located after a scattering compensatingfiber ( DCF ) . Type I showed a addition of 20.8 dubnium at 1556 nanometer. The minimal Noise Figure of Type I was about 7.5 dubniums. Type II: The difference between TypeII with Type Iis that the HFAs recycling residuary Raman pump in a cascaded EDF subdivision located prior to a DCF. The addition of Type II was 21 dubnium at 1556 nanometer. The minimal Noise Figure ofType II wasapproximately5 dubnium. Type Three: Raman assisted EDFA. The peak addition wavelength of TypeIIIwas found to be at 1532 nanometer and the addition was 19 dubnium. The minimal Noise Figure of Type III was about 8 dubnium. [ 8 ] Type II has the larger addition and smaller Noise Figure as comparison to Type I and Type III.Thus, the Type II circuit will be used for simulation in Optisystem package. 2.2 Performance of optical amplifier In the designation of the public presentation of an optical amplifier, some features have been defined. For illustration: addition, noise, optical signal/noise ratio ratio ( OSNR ) , bit error rate, and eye-pattern. 2.2.1 Addition Gain is an of import parametric quantity in amplifiers that measures the elaboration per unit length of fibre. Additions are runing conditions and stuff used dependance. Difference wavelength has difference addition for all stuffs. For a low input powers, the end product power is relative to the addition times the length of fibre: Poutput = Pinput A- Gain A- Length. [ 7 ] The addition may saturate at high input powers. So, the end product power may merely increase in little fraction as input power addition. Basically the optical amplifier has run out of the power it needs to bring forth more end product. 2.2.2 Noise By and large, optical amplifiers will add spontaneously emitted or scattered photons to the signal during the elaboration procedure, and this will do the signal/noise ratio ratio ( SNR ) degrade accordingly. A parameter Noise Figure ( NF ) , which is defined as the SNR ratio between input and end product quantify the SNR degradation.NF= SNRin / SNRout The self-generated emanation can be reduced by an optical filter during pattern. Therefore, the SNR by and large will be dependent on the bandwidth of the optical filters and the spectral power distribution of the self-generated emanation from the amplifier. The self-generated emanation, which is emitted from the amplifier input terminal, may come in the signal beginning ( a semiconducting material optical maser ) , where it can ensue in public presentation perturbations. Therefore, so as to avoid extra noise in the system, it is ever needed to include isolation between amplifier and light beginning. 2.2.3 Signal-to-Noise Ratio Signal-to-noise ratio can entree the public presentation of optical amplifiers, where it defines by the ratio of end product signal to the background noise. The higher the signal-to-noise ratio indicates the quality of the signal is higher. This means that the public presentation of the amplifier is good. 2.2.4 Bit Error Rate The digital input and end product signals are compared utilizing spot error rates ( or ratio ) measurings to measure what fraction of the spots are received falsely. Bit error rates offer a quantitative measuring of signal quality. The typical acceptable spot error rate is 10-9. [ 8 ] 2.2.5 Eye-Pattern The other ways to measure rapidly the noise public presentation of an optically amplified system are through the usage of â€Å" oculus forms † displayed on the CRO. By the superposition of a random sequence of many 1s and 0 spot, such oculus forms are generated. This give a more qualitative position of the noise impressed on the digital transmittal form. [ 9 ] An illustration of oculus form is shown in Figure 2.4. The end product amplitude is the extremum to top out electromotive force output.Jitter is the divergence of the pulsations signal from their ideal places in clip, measured in picoseconds. Figure 2.4: Example of oculus form at receiving system [ 8 ] 2.3 Optical fibre There are two types of fibre, which is individual manner fibre ( SMF ) and multimode fibre ( MMF ) .Light travel in a consecutive line and typically has a nucleus size of 8 or 10 micrometers doing by a individual manner fibre that has a really little nucleus. It has unlimited bandwidth that can travel unrepeated for over 80 kilometers, depending on the type of conveying equipment. Single manner fibre has immense information capacity, more than multimode fibre. Multimode fibre supports multiple waies of visible radiation and has a much larger nucleus comparison to individual manner fibre. The nucleus size of multimode fibre is typically 50 or 62.5 micrometers. The light travels down a much larger way in multimode fibre, leting the visible radiation to travel down several waies or manners. Since individual manner fibre is used for long distance transmittal, it will be discuss in more inside informations in the undermentioned paragraph. 2.3.1 Single Mode Fiber ( SMF ) Light is non reflected or refracted within single-mode fibre, but travels merely along the axis of the nucleus as shown in Figure 2.5. Figure 2.5: Light Transmitted through Single-Mode Fiber [ 8 ] Modal scattering does non be in single-mode fibre since merely one manner is propagated. However, single-mode fibre is capable to other causes of pulse distributing such as chromatic scattering. [ 10 ] 2.3.2 Chromatic Dispersion Chromatic scattering is the phenomenon wherein different spectral constituents of the familial lasersignal travel at different speeds in the fibre, geting at different times at the receiving system. It occurs because optical maser beginnings emit a scope of wavelengths: a primary individual wavelength and a narrow scope of secondary wavelengths on either side of this primary wavelength, as shown in Figure 2.6. The different wavelengths travel at somewhat different velocities through the fibre, and hence arrived at the receiving system at different times. This causes distributing, or scattering, of the standard pulsation. As the length of fibre additions, the difference in arrival times besides increases and the pulsations become wider. The end product pulses finally become identical from their neighbours and spot mistakes occur. Figure 2.6: Output Wavelengths of Laser Source [ 9 ] The bandwidth of a fibre decreases as chromatic scattering additions. Fewer spots can be transmitted in a given clip period because each spot will be wider and hence occupy a longer bit period. Chromatic scattering is the chief performance-limiting factor for single-mode fibre. 2.3.3 Dispersion-compensating fibre ( DCF ) By utilizing a really sophisticated fibre profile, it is possible to minimise scattering over the full wavelength scope from 1300 to 1550 nanometer, at the disbursal of really high loss ( around 2 dB/km ) ; this is known as scattering compensatingfiber. This fibre is designed with negative scattering features, so that when used in series with conventional fibre it will â€Å" undisperse † the signal. Dispersion-compensating fibre has a much narrower nucleus than standard single-mode fibre, which makes it susceptible to nonlinear effects. [ 11 ] 2.3.4 Multimode Fiber vs. Single-mode Fiber Table 2.0 shows a comparing of multimode fibre and single-mode fibre. Because of the many differences between them, these two types of fibre are by and large non interchangeable. Parameter Multimode Fiber ( MMF ) Single-Mode Fiber ( SMF ) Jacket Color Orange ( 62.5A µm ) or Grey ( 50A µm ) Yellow Light Propagation Multiple waies Single way Core Diameter 62.5 A µm or 50A µm ( older ) 9 A µm Link Length Short: lt ; 1 kilometer Long: 10 kilometer to 100 kilometers Typical Wavelength of Transmitter 850 nanometer ( VSCEL ) 1310 nanometer ( FP ) or 1550 nanometer ( DFB ) Performance-Limiting Factor Modal scattering ( Chromatic scattering is undistinguished ) Chromatic scattering ( Modal scattering does non be ) Attenuation Approximate 3dB/km at 850 nanometers Approximate 0.4 dB/km at 1310 nanometer, 0.2 dB/km at 1550 nanometer Bandwidth Low High Sodium 0.28 0.13 Cost Cheaper More Expensive Table 2.1Multimode Fiber vs. Single-mode Fiber Single manner fibre will be used for this undertaking as the transmittal medium since it is used for long distance transmittal, typically 10 kilometers to 100 kilometers. Chapter 3 Methodology This chapter is mentioned about the attack and method used to measure the public presentation of Hybrid Raman and Erbium Doped Fiber Amplifiers.Content of this chapter include the method usage to roll up the informations, informations analysis and factor considered when taking the attack and method. Figure 3.1: Undertaking Flow Chart This undertaking starts with the rubric that is provided by the supervisor. The rubric of the undertaking is public presentation rating of Hybrid Raman and Erbium Doped Fiber Amplifiers ( HFAs ) . By understanding the undertaking range and demands, a thorough reappraisal on specific subjects were done. Figure 3.1 below shows the undertaking block diagram that usage to measure the performanceof Hybrid Raman and Erbium-Doped Fiber Amplifiers. The input to the HFAs is signal power and pump power. The public presentation of HFA is evaluated based on end product power, optical Signal-to-Noise Ratio ( OSNR ) , and Bit Error Rate that can be obtained from the simulation consequence of Optical Spectrum Analyzer. The simulation procedure is repeateduntil the maximal end product power, maximal optical Signal-to-Noise Ratio is obtained and the Bit Error Rate is smaller than 10-9. The different value of input and end product value from simulation consequence will be tabular in tabular array and compared to supply a design parametric quantity for maximal approachable transmittal distance utilizing the intercrossed amplifiers. INPUT OUTPUT Figure 3.1: Undertaking block diagram There are different types of optical simulation package available in the market. For illustration: ModeSYS, OptSim, OptiSPICE, and Optisystem. OptiSystem is an advanced optical communicating system simulation bundle for the design, proving and optimisation of virtually any type of optical nexus in the physical bed of a wide spectrum of optical networks.The OptiSystem Component Library includes 100s of constituents that enable users to come in parametric quantities that can be measured from existent devices. Therefore, Optisystem package will be usage to imitate and measure the public presentation of the Hybrid Raman and Erbium Doped Fiber Amplifiers. However, the execution of HFAs into Optisystem package will merely be start at PSM 2. Chapter 4 PRELIMINARY RESULT 4.1 Discussion From through reading and research, the circuit that will be utilizing for the simulation is as in Figure 2.3, Type II of single-pump dispersion-compensating Hybrid Raman and Erbium-Doped Fiber Amplifier ( HFAs ) . From Figure 2.3, the intercrossed amplifier recycling residuary Raman pump with a cascaded EDF subdivision located prior to a scattering compensatingfiber ( DCF ) . The Raman pump beginning consists of two optical maser rectifying tubes runing at 1455 nanometer and 1465 nanometer, severally. By uniting the two pump wavelengths with a inactive pump combiner, a entire power of up to 500mW was available. Since individual manner fibre is used for long distance transmittal, and the chromatic scattering is the chief performance-limiting factor for single-mode fibre. Therefore, a 12.6 kilometer DCF with 0.55 dB/km fading at a wavelength 1550 nanometer was used to counterbalance the fading. The 12.6 kilometers DCF with a group speed scattering of -98 ps/nm/km at 1550 nanometer can supply sufficient scattering for counterbalancing a 70 kilometer long individual manner fibre based transmittal span. By simulation, it is expected to acquire a addition of 21 dubnium and Noise Figure of 5 dubnium. 4.2 Decision At the terminal of the undertaking, it is expected to supply a design parametric quantity for maximal approachable transmittal distance utilizing the Hybrid Raman and Erbium Doped Fiber Amplifiers. Some of the restraints that limit the maximal transmittal distance are pump power, signal power, type and length of fibre used. The public presentation of the HFAs will be evaluated based on the amplifier ‘s addition, Optical Signal-to-Noise Ratio ( OSNR ) , Bit Error Rate ( BER ) and Noise Figure obtained from the simulation consequence. A addition of 21 dubnium, Noise Figure of 5 dubnium, and bit error rate less than 10-9 should be obtained in simulation consequence.

Government Interventions on Monopoly Power

Question: Discuss about the Government Interventions on Monopoly Power. Answer: Introduction The reason for choosing this topic is to discuss the various tools and methods adopted by the government to address the economic situation created as a result of market failure from monopoly power. It will provide various ideas of economic concepts which are integral for knowing aspects of market failure, monopoly power etc. Various methods can be adopted by the government to control the market failure caused as a result of monopoly power (Cairns and Calfucura, 2012). This may include implementation of taxes on certain commodities, enforcement of laws and regulations, creating buffer stocks, providing subsidies to certain producers etc. The entire essay is divided into three main sections. The first part acts as introductory information where the topic is being discussed. The second section is the main body which will discuss various aspects of market failure and its types. Different approaches of the government will discuss critically and their advantages and disadvantages will be a nalysed (Rios et al., 2013). Five intervention strategies are being identified namely indirect taxes, use of price caps, and use of subsidies. The other strategies are use of legal intervention and use of information. The final section refers to the concluding statements wherein the important points will be analysed in brief. When referring to pure monopoly it shows a single seller. The cases of pure monopoly are very less. However the aspect of monopoly power is more ambivalent and can be present even in case where there is presence of more than a single supplier. This is possible in the case of markets where only two firms have market power i.e. duopoly and where few firms hold market power i.e. oligopoly. Monopolies are created in case of different situations. It can be when a particular firm has total and exclusive control resources which are scarce (Twomey and Neuhoff, 2010). An example can be cited from UK. The sole business of telephone cables is owned by British Telecom and they are effective in most of the houses and businesses in UK. Monopoly is created when the government provides monopoly status to a single firm like the Post Office. Monopoly is again created when firms are owners of patents and copyrights allowing them exclusive rights to sell the product and protecting the product as intellectual property. For example Windows is a brand name of Microsoft. The contents of the software of this company are protected from users who are unauthorised. Monopoly power is also created when two companies merge to occupy a dominant position in the market. Monopoly power is maintained in many ways. If the company is able to reduce the cost of production and increase the scale of business and volume they will have advantage over new entrants to the market (Ariss, 2010). Often few companies reduce their prices to such an extent that it puts pressure on competing rivals. This is known as predatory pricing. Moreover heavy expenditure on advertising by existing firms hinders new firms from entering the market. This is because new firms lack the capital base for such expenses (Swinnen and Vandeplas, 2010). Again maintaining cont racts between suppliers and retailers gives impetus to monopoly power. It is important to understand how monopoly power leads to market failure. The problem with monopoly is that high profits are made resulting in poor effectiveness of allocation. Those firms having monopoly power try to derive a price from the consumers or buyers which is more than the cost of raw materials which are used for manufacturing the product (Dodgson et al., 2011). Due to the higher prices, the buying capacity of the consumers decline. This leads to needs and wants of the consumers not getting satisfied. This dissatisfaction is a result of the products not being consumed properly. Increase in prices reduces the consumer surplus and impacts the welfare of the consumers. Thus there is a negative impact on the households that have low incomes. Market failure is when the markets are not competitive enough and causes dissatisfaction for the society. Market failure can be either complete or partial. A market fails completely when there is absolute absence of product supply (Gilmore et al., 2010). The market failure is partial when there is functioning of the market but suffers due to wrong quantity of production and wrong pricing. There are various factors leading to market failures. Due to environmental pollution the society has to bear the costs rather than the companies. These are known as negative externalities (Pitelis and Teece, 2010). Again if there the government provides health care and education, the society is benefited over the producers. This is known as the positive externalities. Again market fails when goods having social value are under produced while goods lacking social value are increasingly produced and consumed. Often the private sectors in a free economy charge high prices in order to derive profits on pure and quasi public goods. This leads to dissatisfaction and needs not being met. Market dominance leads lack of supply and increased prices damaging welfare of the consumers (Stiglitz, 2010). Another reason of market failure is factor immobility which leads to unemployment and harm to efficiency in production. Often inequality in distribution of income and social exclusion lead to market failure. Potential advantages of monopoly power It is true that market domination and monopoly power has a negative impact over consumers and results in lack of supply and market failure. However there are certain possible benefits of monopoly power. Monopoly power leads to economies of scale. Consumers will benefit in the long run since the average costs will be constant and eventually the prices will get lowered. Thus it is always beneficiary that public services are run by a single organisation so that there is a fixed pricing (Acemoglu and Robinson, 2013). However monopoly power always does not lead to economies of scale. Hence there is no certainty that the average prices will be lowered in the future leading to reduced prices. Monopoly power can also help in research and development. The supernormal profits can be utilised for investment in novel products and innovations which will eventually help the consumers in the future. This can be related with the oil and gas industry. Again domestic monopoly might face competition fr om the international markets which will force them to reduce costs leading to efficiency and economies of scale (Rubalcaba et al., 2010). There are various methods by which government can put checks and measures on monopoly power and improve upon the situation of market failure. Some of them will be discussed below- Use of indirect taxes- Indirect taxes refers to the tax which the government imposes on the producers to increase the cost of supply. This can be showed with the help of diagrams. The vertical distances between two supply curves refer to the amount of tax. Hence due to the presence of taxes the supply becomes less at every price level (Sakovics and Steiner, 2012). As a result of the lowering supply the market price increases leading to the demand fall. Thus a new equilibrium output is established. There are different kinds of indirect taxes. There may be a specified tax wherein it is directed that a certain amount of tax will be charged on a single unit of the product sold (Pirard, 2012). For example, the government may charge 6 as tax for one kg of sugar that is being sold. Another kind of indirect tax is ad valorem tax which refers to a percentage of tax charged on the unit price of a product. Suppose the price of one cigarette is 2, the government may charge 10% as ad valorem tax on the price. The main form of ad valorem tax which is charged in UK is in the form of value added tax i.e. VAT. Currently value added tax contributes to a revenue of over 100 billion pounds to UK treasury and public funds every year (Salanie, 2011). The taxes levied on fuel provide more than 25 billion pounds of revenue every year. UK government generates almost 10 billion pounds form levying tax on tobacco products every year. Duties paid for flight passengers generates up to 3 billion pounds for the government every year. Thus from the diagram it can be inferred that ad valorem taxes may cause significant shifts in the supply curve. This is due to tax being a percentage of the unit cost of supplying a product. In UK the standard rate of value added tax is 20%. Thus a product that will usually cost 50 pounds will cost 60 pounds after the value added tax is levied (Aaron and Boskin, 2011). However the problem of indirect taxes is that the producers increase their prices by adding the tax rates and the ultimate bearer of the burden are the consumers. Government subsidies- Subsidy refers to any kind of support by the government usually financial in nature. These are usually offered to a class of producers and at some times to the consumers. For every unit of product receiving subsidy the market supply curve shifts outwards. This results in the equilibrium price becoming low. Hence the total expenditure on subsidy can be calculated as the subsidy provided for a single unit multiplied by production level. Thus subsidies can be used by the government for various reasons. The reasons can be social, political or economic (Ehrenberg and Smith, 2016). Subsidies help loss making industries in times of recession by protecting jobs. With the help of subsidies health care facilities and treatments become affordable and accessible. Subsidies encourage investment in small industries and this leads to increased output. The government provides subsidies to poor families in the form expenses for child care and food subsidies. With the help of subsidies the companies can lower the expenses for training and hiring employees (Brown et al., 2011). Price caps- Maximum prices or price caps are used by the government to hinder the market prices from increasing at a certain level. Price caps or maximum prices are in several forms. The government can set a ceiling for house rents. This is for the protection of poor tenants from being manipulated and ill treated (Walras, 2013). The government also applies maximum prices on energy resources to reduce fuel bills. Water companies are also given direction to maintain a certain price on its supply. Money lenders also have to adhere to limits in terms of charging interest rates. Hence price caps ensure that there is healthy competition in the market. It is done for the welfare of the consumers. It also induces the businesses to reduce the costs to gain profits. However caps on prices reduce profits and discourages investors (Blair and Kaserman, 2014). The firms raise their prices leading to pressure on the ultimate consumer. Governments role in information sharing- Market failure often occurs if people consume products which have negative externalities i.e. increase social costs over private costs. Thus the government carries out campaigns informing people and they set minimum age for consumption. Laws and regulation- The government controls monopoly with the help of anti monopoly laws like competition laws (Gual and Mas, 2011). These legislations try to remove unhealthy competition, prevent unfair discrimination of prices and they fix the prices to be competitive. Conclusion From the above discussion various economic concepts can be understood. The concept of monopoly power has been discussed with the help of diagrams. It is a misnomer that there are only demerits of monopoly power. Monopoly if used constructively by the companies can benefit the service users in the long run. Market failure can be attributed to various reasons. They can be tackled with the help of different government methods of intervention. References Aaron, H., Boskin, M. (Eds.).

Persuasive Paragraph Outline Essays - Appetite Stimulants

Persuasive Paragraph Outline Topic: Marijuana legalization in Canada Topic sentence: ("should / should not" statement) The legalization of marijuana in Canada should bring more benefits than downfalls to our society. A. Major Point #1: Marijuana has medical benefits. 1. Explanation: THC can increase appetite and reduce nausea. THC may also decrease pain, inflammation (swelling and redness), and muscle control problems. It also has the ability to help kill certain cancer cells in the body. These drugs are prescribed as appetite stimulants in AIDS patients and for chemotherapy- related nausea and vomiting. They are sometimes used off-label for similar symptoms in other conditions. 2. Support (Examples, facts, statistics, etc.): "Recent animal studies have shown that marijuana extracts may help kill certain cancer cells and reduce the size of others. Evidence from one cell culture study with rodents suggests that purified extracts from whole-plant marijuana can slow the growth of cancer cells from one of the most serious types of brain tumors." https://www.drugabuse.gov/publications/drugfacts/marijuana-medicine "An oral spray nabiximols (Sativex) is approved in other countries for treatment of multiple sclerosis muscle spasticity and cancer-related pain not managed by other pain medication" https://www.health.harvard.edu/blog/the-health-effects-of-marijuana-from- recreational-and-medical-use-2016081910180 B. Major Point #2: 1. Explanation: The legalization of marijuana in Canada has the potential to aid in lowering the Canada's deficit. 2. Support (examples, facts, statistics, etc.): "The bottom line is that federal (and) provincial governments might reap as much as $5 billion from legalization, but only if all the underground sales are effectively curtailed" http://www.cbc.ca/news/politics/pot-revenue-government-5-billion-1.3423705 The total impact for Canada's economy from a legal weed market - including growing and distribution, pot paraphernalia, increased tourism and business taxes - would amount to between $12.7 billion to $22.6 billion annually. http://www.huffingtonpost.ca/2016/10/27/marijuana-legalization-market-size- canada_n_12676754.html C. Major Point #3: Some deadbolts provide extra security for French doors by locking from the inside with a key. 1. Explanation: It would make research on marijuana much easier, as currently there are few institutions that are legally allowed to research marijuana. It could help to prove or disprove all the notions that smoking marijuana isn't as bad for the body as smoking tobacco or drinking a lot of alcohol. Wrap-up (concluding) sentence(s): The many advantages of a deadbolt make it a good investment for a homeowner; however, the type of door frame is another consideration in home security. The sentence in blue is a transitional sentence. It helps to introduce the next paragraph. You will use transitional sentences for your Research Essay, but not in the Paragraph Assignments.
