Spirituality in Health Care - Essay Example As a means of understanding this to a more effective degree, the following analysis will discuss the role that spirituality plays in helping to address this primary task. As such, for purposes of this analysis, the author will focus specifically upon the realm of the way in which spirituality can play a role in attending to the needs of the patient, the way in which a clear delineation between a given set of beliefs and/or proselytize nation must be separated from spirituality, and the innate importance of being continually cognizant and aware/appreciative of different beliefs and the different multicultural approaches to spirituality that the patients might have. Only thorough exemplification and examination of these topics will give more effective understanding of how spirituality can be engaged within the realm of healthcare provision. The following analysis will provide a brief introduction into the topic as well as discussing the way in which three separate faiths integrate with a comparative approach to healthcare. As such, the three faiths which will be referenced are as follows: Buddhist, Shinto, and Baha’i. ... nderstood that spirituality is still a very delicate topic due to the fact that it does not exist, nor is represented, categorically among each and every patient that seeks a level of treatment (Reimer-Kirkham et al. 203). Instead, spirituality is a highly personal component of an individual’s worldview. As such, it is the ultimate role of the healthcare provider to be cognizant of this and not to seek to foster any particular type of approach to spirituality. Instead, merely listening and being aware of any needs/beliefs that the patient might represent to the healthcare provider is a preliminary and essential task. In this way, the first faith to be discussed, Buddhism, it must be understood that the Buddhist approach to healthcare provision is ultimately quite depressing with regards to the way in which care and treatment can be provided. From the Buddhist interpretation, even the highest form of care can only be viewed from the standpoint that death can merely be delayed a nd suffering itself should not necessarily be sought to be averted in and of itself due to the fact that it has an innate potential for purification and the ability to allow the individual to come to a greater appreciation for life and an escalation towards the state of nirvana. All of this of course springs from the understanding that Buddhism holds as a tacit truth that suffering is a part of life and as such should be accepted without actively seeking to diminish it. With that being said, it is of vital importance that healthcare provider is not a means anyway, or at any time, to seek to promote a particular worldview or proselytize their own belief system to the patient. This is of course due to the fact that this represents a clear breach of professionalism and an overstepping of the

Free Vibration Of A Cantilever Objective

Free Vibration Of A Cantilever Objective The purpose of this experiment is to determine the natural frequency of a cantilever beam study both undamped and damped free vibration motion of a cantilever beam. Vibration is the periodic motion of a body or system of connected bodies displaced from a position of equilibrium. In general, there are two types of vibration, free and forced. Free vibration is maintained by gravitational or elastic restoring force. Forced vibration is caused by an external periodic or intermittent force applied to the system. Both of these types of vibration may be either damped or undamped. Undamped vibrations can continue indefinitely because frictional effects are neglected in the analysis. Basically, if a system that is subjected to an initial disturbance and is left to vibrate on its own, the subsequent vibration is known as the free vibration. Vibrations without damping would result in a continuous vibration of the particular oscillatory body. As a matter of fact, it will produce a displacement-time graph of such nature as shown in the following figure. This graph is commonly referred to as the simple harmonic motion. http://upload.wikimedia.org/wikipedia/co mmons/4/44/Simple_harmonic_motion.png Figure 1: Simple Harmonic Motion (Displacement-Time Graph) However, in reality, just as with many other scientific theories, this is impossible because friction and other forces are present both internally and externally. As the system is subjected to these forces, this phenomena is called damping. The principle effect of damping is to reduce the amplitude of an oscillation, not to change its frequency. So, the graph of the amplitude of a normal damped oscillation might look like the following: http://www.efunda.com/formulae/vibrations/sdof_images/SDOF_UnderDamped_Response.gif Figure 2: Graph of Damped Oscillation (Displacement-Time Graph) Apparatus and Materials: 1.

Strain gauge 3. Strain recorder 4. Viscous damper Experimental Procedures: Figure 3: Experiment Setup without Viscous Damper Figure 4: Experiment Setup with Viscous Damper The computer and the strain recorder were switched on. The strain recorder application software was started by double clicking on the DC104REng shortcut icon on the computer desktop. The experiment setup was shown in Figure 3. The operation of the strain recorder and the recorder application software were referred to the operational manual. The viscous damper was removed if it was attached to the beam. The beam was held and displaced by, ymax, -20mm, -15mm, -10m, -5mm, 0, 5mm, 10mm, 15mm,and 20mm. The strain recorder reading for each displacement value from the Numerical Monitor screen of the application software was recorded manually. The relationship of the displacement (of the free end of the beam) and the strain recorder reading was obtained by plotting an appropriate graph using a spreadsheet. The beam is displaced by 30mm and the beam is left to vibrate on its own. The strain recorder reading was recorded by clicking on the Play and Stop button. The recorded file was retrieved by clicking on the Read USB button. The graph of the beam displacement versus time, t was plotted. The experiment was repeated by using beam displacement of 50mm. The viscous damper was connected as shown in Figure 3. Steps 7 and 10 were repeated by using beam displacement of 30mm and 50mm respectively. a) Theoretical Calculations As given in the experiment: Modulus of elasticity of aluminium,E = 70 GPa Length of the cantilever beam, L = 0.927m Width of the cantilever beam,b = 0.019m Thickness of the cantilever beam, h = 0.006m Mass of the cantilever beam, mcantilever = 0.293 kg Mass of the damper, mdamper = 0.122 kg b) Experimental Results and Calculations Free Vibration of Cantilever Beam at 30mm Displacement Natural Circular Frequency of Beam with Viscous Damper, The free vibration of the theoretical natural frequency of the cantilever beam in this experiment is 5.75Hz while the experimental natural frequency of the cantilever beam is 6.25Hz for amplitude of 30mm and 6.25Hz for amplitude of 50mm. The viscously damped vibration of the theoretical natural frequency of the cantilever beam is 3.45Hz and the experimental natural frequency of the cantilever beam for amplitude of 30mm and 50mm are 3.57Hz and 3.57Hz. Percentage error, % x 100% Free Vibration of Cantilever Beam at 30mm Displacement Percentage error, %= x 100% =8.70% Free Vibration of Cantilever Beam at 50mm Displacement Percentage error, %= x 100% =8.70% Viscously Damped Vibration of Cantilever Beam at 30mm Displacement Percentage error, %= x 100% =3.48% Viscously Damped Vibration of Cantilever Beam at 50mm Displacement Percentage error, %= x 100% =3.48% In this experiment, it is calculated that the percentage error for the free vibration is both 8.70% for 30mm and 50mm. For the viciously damped vibration, the percentage error for the 30mm and 50mm were both 3.48%. The results of the experiment were slightly inaccurate. This may be caused by the external force which is the air resistance as the beam oscillates. Another factor is caused by parallax error which occurred during the measuring of displacement before the beam was released as our eye level was not perpendicular to the scale of the metre rule. When the beam is released, it slightly hit the bottom of the container which decreases the original force released drastically which affects the amplitude of oscillation. Furthermore, the Modulus of Elasticity(Youngs Modulus) was given, which might not be accurate. All these source of error may affect the results of the experiment to be inaccurate. The results of the experiment can be improved by measuring the Modulus of Elasticity. Using a deeper container would also avoid the damper to hit the bottom of the container. Furthermore, the experiment can be done in a vacuum box to avoid air resistance. Eye level should be adjusted until it is perpendicular to the metre rule scale. This steps can increase the accuracy of the results. The damped period, damped natural frequency and the damping ratio of the system of free vibration is. When the amplitude is 30mm or 50mm for both cases, they have the same damped period, damped natural frequency and damped ratio. The percentage error for the free vibration of 30mm and 50mm were both 8.70% while for the viciously damped of 30mm and 50mm were both 3.48%. This indicates that the difference in amplitudes do not affect the frequency of the oscillation. From the general equation of frequency : , where c=speed of wave ÃŽÂ »= wavelength This formula proves that amplitude or displacement does not affect the frequency of the oscillation. If the strain gauge is mounted on the other end of the cantilever beam, the results would be not accurate as the gauge is very sensitive to changes. At the other end, there is not much difference in the change of length which affects the strain. In Figure 3, the strain can be detected more easily as the change in length is very obvious. This is because when the free end is free to vibrates, the vibration will be strong but the compression and tension that results on the surface of pressure sensor is not that strong. Conclusion : The theoretical natural frequency , for this experiment is 5.75Hz for free vibration cantilever. The value of both 30mm and 50mm frequency obtained were 6.25Hz which have percentage error of 8.70%. Whereas, the theoretical damped natural frequency , is 3.45 Hz. The value of both 30mm and 50mm frequency obtained were 3.57Hz which have percentage error of 3.48%. Furthermore, the results proves that the displacement does not affect the vibration(frequency) of the oscillation of the cantilever beam.

Martin Luther King Jr. :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  After the Birmingham, Alabama newspaper published â€Å"The Public Statement by Eight Alabama Clergymen† calling Martin Luther King Jr.’s activities â€Å"unwise and untimely,† King wrote a response back from jail arguing each point the clergymen had made in their â€Å"Public Statement.† In the â€Å"Letter from Birmingham Jail,† King points out that he is not an outsider since the people of Birmingham invited him and that since they are all within the United States, nobody should be even considered an outsider. Being a fighter of injustice, King says, he sought to negotiate with the white community of Birmingham, but they refused to comply. Then, he illustrates to them that the tension amongst the groups is many times good because it leads to action and negotiation. He further explains that calling the actions of Negroes â€Å"unwise and untimely† is denying them justice, which they have been waiting for too long. Moreo ver, King explains that laws can be just and unjust, and that he will only obey just laws that agree with the moral code and disobey laws that do not unlike the white churches, which permit prejudice and hate even though they should preach brotherhood and love. Lastly, King points out that Negroes will win their freedom in the end because it is their right and God’s will. To argue his points in the â€Å"Letter† King uses each of the three rhetorical appeals: ethos, pathos, and logos. In this essay, I will try to prove that one appeal is more effective than the rest, but first in order to help one understand what these appeals mean, I will use Arthur Quinn’s definitions of what the three appeals entail. The first appeal, the ethos, tries to persuade an audience to agree with an argument by using the reputation and character of the speaker or writer. For instance, a well-liked political leader might hold a strong ethos in the eyes of his constituents, and therefore his opinions on issues might convince his constituents to hold the same opinions whether or not they know anything about the issue. In contrast, the pathos appeal attempts to persuade an audience by targeting their emotions in attempt to gain their sympathy for the argument. An example of this appeal can be seen in TV commercials fundraising money for impoverished children. The final appeal, the logos, attempts to persuade an audience using logic and good reasoning.

Analysis of two brands of commercial Bleaches Essay

Analysis of Two Brands of Commercial Bleaches Objective To determine the concentration of sodium chlorate(I) (NaClO) in two commercial bleaches and compare the two bleaches on both concentration and price. Procedures 1. 10. 0 cm3 of the bleach â€Å"KAO† was pipetted into a clean 250 cm3 volumetric flask. It was made up to the mark using deionized water. 2. 25. 0 cm3 of the diluted solution was pipetted into a conical flask. 3. 10 cm3 of 1 M potassium iodide solution and 10 cm3 of dilute sulphuric acid was added into the conical flask also. 4. The mixture in the conical flask was titrated against the 0. 0992 M sodium thiosulphate solution. 5. Three drops of freshly prepared starch indicator are added into the conical flask when the reaction mixture turned pale yellow . 6. The mixture was titrated to the end-point. 7. At the end point, the solution turned from dark blue to colourless. 8. Steps (1) to (7) were repeated with another bleach â€Å"LION† Results Concentration of standard sodium thiosulphate solution : 0. 0992M Brand 1 Trade Name : KAO Bleach Price : $7. 33per dm3 ($11/1500mL).

Based on the calculated results, decide which of the two brands of bleach is a better buy. When compring the costs per one gram of OCl- of KAO(0. 277/g) and LION($0. 185/g), as we can pay a lower price ($0. 185)to buy the same weight of active ingredient (OCl- ) in LION bleach, LION bleach is a better buy. 3. Explain why potassium iodide and sulphuric acid must be in excess. ClO-(aq) + 2I-(aq) + 2H+(aq) i I2(aq) + H2O(l) + Cl-(aq) From the equation above, iodide ions and hydrogen ions react with Hypochlorite ions to form iodine ,water and chloride ions. To determine the actual number of mole of ClO- ,all ClO- ions sholud react to give iodine. KI (I-) and H2SO4 (H+) must be in excess to ensure all ClO- has been converted into Cl- ions. Then the number of mole of I2 produced is calculated by titrating against sodium thiosulphate and hence the number of mole of ClO- ions can be calculated by ratio: No. of moles of ClO- = No. of moles of I2 In other words, excess potassium iodide and sulphuric acid are used for ensuring all ClO- ions are reacted react to give iodine. Moreover,dilute sulphuric acid is added to increase the rate of reaction. If KI and H2SO4 are not in excess, some of the ClO- ions are not converted into Cl- . Consequently the calculated number of mole of ClO- ions present would be smaller than the actual one since the number of mole of ClO- ions which are not converted into Cl- are not taken into account. 4. Bleaching solution may deteriorate for two main reasons. One is the attack by carbon dioxide in air according to the equation: 2ClO-(aq) + CO2(aq) i CO32-(aq) + Cl2(aq) What is the other possible reason? Under normal condition,Hypochlorite ions decompose to give oxygen and chloride ions. Ionic equation: ClO-(aq) i O2(g) + 2Cl-(aq) Chemical equation: NaClO(aq) i O2(g) + 2NaCl(aq). The rate of the reaction above can been increased at high temperature or under sunlight. When sodium hypochlorite is heated or evaporated, sodium chlorate and sodium chloride will be formed. Chemical equation: 3 NaOCl(aq) i NaClO3 (aq)+ 2 NaCl(aq) 5. The starch indicator should not be added too early. Why? Starch is often used in chemistry as an indicator for redox titrations where iodine is present as starch forms a very dark blue-black complex with iodine. Moreover,the indicator is not affected by the presence of iodide (I-). In order for the the starch solution to change colour, both starch and iodide must be present. Starch forms an unstable complex which is blue coloured in low concentrations of iodine. However, this complex is in high concentrations of iodine . If starch solution is added too early, the conical flask still contains high concentration of iodine. As a result, highly stable complex is formed,the starch indicator then cannot be decolourised and the complex will spoil the reaction medium. Consequently, the titration cannot continue. Therefore the iodine must be diluted first with the titrant ,sodium thiosulphate to ensure no higly stable complex is formed. After that the starch can be added.

Climate Change And Economic Policy

Climate change is defined as â€Å"Change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods†(Bruno and Mehmet 2010). Modern methods of production create greenhouse gasses as a negative externality via the market failure and government intervention is needed to rectify the situation. Climate change is an issue for the Australian government as it needs to intervene to correct the market failure caused by the free markets inability to provide property rights to mitigate damages caused by the negative externality. (Calhoun 2010) The greenhouse gas externality is a by-product of the production of goods and services via the over-production of emissions. Dr Peter John Wood argues that† climate change is an indisputable threat† and on that basis, as well as the world stage Australia has taken the reins in acting upon climate change. An externality is defined as† are the unintended consequence of one economic agent’s economic activity that affect another agent’s economic activity, but which are not adequately priced through the market (Sonia and Jeff 2011)†. This is also known as market failure and requires government intervention to be able to rectify the problem due to a lack of property rights and correct mitigation for parties involved with the transaction. In this case, one form of the market failure is because the cost of CO2 is not factored into the transaction price. The Gillard government continued a legacy that was started with the Howard government back in 2007 that saw a Carbon Emissions Trading scheme take part in the Australian government to tackle Australia’s greenhouse gas emissions (Chris 2011). The Carbon tax was implemented on June 1st 2012 and has been controversial amongst politicians and economists alike according to Clive’s article â€Å"Australia's Carbon Tax: A Sheep in Wolf's Clothing†. The steps taken to implement a policy should be understood first before critiquing from different viewpoints. The four major points of policymaking are: 1. Specify the goals of policy 2. Identify the targets 3. Specify the policy instruments 4. Model the economy linking the instruments to the targets Using this framework, the goal’s of the policy are to mitigate damages caused by the production of greenhouse gasses on the (global) environment on a national scale and decrease the amount of pollution via increasing the price of polluting. The targets of the policy are the agents involved (Firms producing pollution, environment and households) with the transactions. Firms are the largest creators of the pollution and the households are directly affected by price increases, therefore their welfare post-tax needs to be considered in a socially acceptable policy. The policy instruments include subsidies to the households most affected by the increases in prices of amenities as well as the Pigovian Tax on polluting (Energy 2012). Lastly, the model that directly links the economy to the instruments proposed can be shown below. Tax brings the externality into equilibrium with the social cost. The amount of gain to the social benefit is the darker area and is also the taxation revenue collected on behalf of the government. This also decreases output by the difference in Original output-New output. This can also be shown on a Supply and Demand graph. The graph to the right illustrates the effectiveness of the tax on the existing market price and therefore reducing the quantity of pollution emitted. This tax is directly placed on the top 500 polluting firms in Australia which account for the majority of the pollution via production. The Department for Climate Change and Efficient Energy published their â€Å"Forth Assessment Report† outlining that â€Å"There is clear evidence that our climate is changing, largely due to human activities†. One can infer that the government is acting morally and taking partial responsibility for these human activities, hence action for change and mitigation. Market failure is defined as the inability of the market being able to deliver an efficient level of goods and or services (Calhoun 2010). This is an important aspect when determining what aspects of a policy are vital in addressing the issue at hand, because the situation of pollution is a non-Pareto optimal situation due to the negative externalities created in the transaction between agents. The government’s intervention due to the market failing is justified by its role in the G8, Kyoto Protocol and its response to the public on the matter (â€Å"Australia to have leading role in carbon mitigation† 2007). Another reason is that property rights are not defined clearly with the environment, therefore the government intervention to make the Marginal Social Cost equal the Marginal Social Cost via a Pigovian tax, decreasing the amount of negative externality produced (greenhouse gasses).(Bruno and Mehmet 2010) Macro-economically speaking, this issue impacts both Australia’s macroeconomic goal of efficient resource allocation and sustainable economic growth. Due to high public opinion on green alternatives and clean production, changes in consumer preferences will mean that some goods and services provided using traditional fossil fuels or unsustainable methods may be boy-cotted or fall second preference to ‘green goods’(Kathleen 2012) The Efficient resource allocation goal of Australia addresses â€Å"†¦where resources are allocated in the most efficient manner†(Weng 2008). The environment is a common resource and traditionally has not been defined to any specific owner. Firms may utilise the environment (clean air, sunshine and or clean water) as a factor of production, examples may include Personal Trainers or tour guides. With a market failure existing, it renders the goal incomplete as there is an excess of pollution and undersupply of environment as it is a rival good. Either the polluters must reduce their output of pollution or they must mitigate the affected agents. This causes a problem in the regard, whom is affected by the pollution and by how much does the affected agents need to be mitigated for. Sustainable economic growth in the long term is impacted by climate change. Not only will Australia be affected by the hypothesised changes to temperature for standards of living, but the changes may affect agricultural output and goods demanded by countries importing (supporting) clean production methods. Australia, by implementing policy change enables the economy to be in a better position to respond to act with funds allocated via the policy impact (â€Å"Australia: Australia Prepares for Carbon Tax† 2012). Comparing the current Carbon Tax (Clean Energy Bill) to alternatives that have been proposed such as Carbon Trading Schemes and Subsidies for Clean Investment have both advantages and disadvantages (Calhoun 2010). Australia’s Carbon Tax initially is a fixed price of $23 per Metric Tonne of Carbon Dioxide emitted from the top 500 polluting companies in Australia(Harris 2012). This in its simplicity is a Pigovian Tax, which is used to deter consumption/production of a good or service that causes the negative externality. Simultaneously the Indirect tax signals the taxed firms that they should spend investment capital on ways to lower their output of CO2 emissions (Carrie 2011). Pigovian taxes are designed to increase the price of the good that causes the negative externality by the amount that best reflects the cost to society in the production of the good which will internalise the effects of the externality (Carrie 2011). Examples of these in Australian society include the Alco-Pop tax and tobacco tax. In the case of the Carbon Tax, the good being taxed is pollution and the parties being mitigated are the Australian government on behalf of the environment in which it is representing, in effect the environment is gaining property rights in this explanation. The Pigovian tax, when applied will cause a reduction in the level of pollution due to the cost added. This will vary from firm to firm due to the elasticity of the cost to pollute. It is safe to assume that all firms are elastic with pollution expenses; therefore the economics of the tax are sound. Pigovian taxes have been praised for their simplistic approach to combating both losses of competitiveness due to inefficient methods of production and on goods themselves which are non-essential for consumption when viable substitutes are available according to Harris’s economic survey in 2012. Examples include using solar power on mine sites instead of Gas or Coal power. Pigovian Taxes however are not ideal in the case of Carbon Leakage, whereby firms choose to produce their goods offshore in countries that are not yet or not participating in Carbon Reduction. It reduces Australia’s carbon footprint, however the loss of production in Australia mean relative to before the tax, there is a reduction in output. (Dellaware 2011). By contrasting these to alternative methods to combat climate change such as an Emissions Trading Scheme (Cap and Trade) or the Carbon Offset system. All theoretically are able to reduce the level of the negative externality, however they all have different dynamics to each other and need to be applied using the framework aforementioned in the essay. The Cap and Trade system allows for the Coasian Bargaining of the right to emit greenhouse gasses as part of production of a firm. These permits would be of a set supply, and would limit firms to a ‘cap’ of pollution. These would be traded in the open market meaning that the market subject to demand and elasticity by a firm, determines the price of the permit. This would encourage firms to innovate and reduce the number of permits needed to produce, or be more efficient with the given quota of pollution per year.(Kathleen 2012) Advantages of the Cap and Trade system mean that the total level of greenhouse gases are controlled, IE a set amount per year meaning that it is easier to attain goals from the Kyoto Protocol. International trading markets are also proposed and feasible meaning that there is greater competition for permits which leads to more efficiency domestically. Firms that are unable to compete or innovate into cleaner greener methods are either absorbed by larger more efficient and environmentally viable companies or liquidate, meaning less pollution output. Another advantage is that there is little regulation and or further government attention required to maintain the Cap and Trade system. Because the market forces determine prices between firms, the need for a middle man is removed. Comparing this to a Carbon Tax, where constant auditing, monitoring and enforcement is both time consuming and expensive from a tax payers perspective. Comparing the two graphically below show the changes in price and quantity in the strict control of either supply of increase of price. The Carbon tax is indirect, it controls the price movements, which affect the quantity, and the Cap and Trade system controls the supply, which then determines the price. The biggest disadvantage to not controlling the price of pollution as oppose to the quantity is that it does not promote efficient investment on clean alternatives to production and instead causes prices to rise of the permits, allowing larger companies to purchase the right to continue polluting and drive out smaller less profitable companies, provided they can’t sustain operation by selling excess permits to excessive polluters. Graphically, they yield the same result however; Clive argues that the amount of red tape needed to maintain the Cap and Trade System is not viable. Introducing the Carbon Offset scheme, means that carbon offsets are purchased which in turn mitigates the marginal private cost of the firm to equilibrium level. Firms can only pollute according to their offset amount and has been successful in Europe with 5.5 Billion dollars of offsets traded according to Bruno and Mehmet’s paper on Governance and the Carbon impact. Advantages exist in the offset scheme whereby it guarantee’s firms to take positive action/investment due to money spent on offsets directly in the form of buying credits from firms specific for reducing pollution and or investment on re-forestation and cleaner methods of production. Other arguments exist stating that having a Cap of pollution will force in-efficient firms to find the lowest cost method to reduce their pollution. Again, like any alternative to the Carbon Tax, much more bureaucratic procedures, monitoring costs and governing bodies are required to manage such a proposal (Oh 2007). 1. Similarities exist between the two policy options in that both require a base measured level of pollution to which caps and prices can be compared 1. Both systems will generate revenue via the increase of the Marginal Private cost which can be distributed via the governing body. 1. Both systems will require a governing body to standardise and monitor activities to be equitable (International-Emissions-Trading-Association 2011) Using this information, the policies will affect different groups of individuals differently. The Carbon Tax will have some impact on households, but greater on the top 500 firms. Understanding how it will affect each party will enable a better understanding of the Pareto Efficiency concept. Households under the Carbon Tax will be charged more for amenities and certain activities such as air travel. Using the graph below it is clear that electricity is the largest producer of greenhouse gases and will have the largest impact via the tax. increase of costs of using electricity, any household that earns less than 80,000 dollars a year will benefit from subsidies and household assistance packages from the Liberal Government (Energy 2012).Households will also gain in subsidies and other cleaner initiatives from the government via the revenue collected from the tax which will increase their standard of living, proposed by the new energy reforms(Energy 2012). Linking back to Figure 1, the gains in Social Benefit are the largest gains that the households have, which economically speaking should be a new Pareto optimum specific to householders. Firms on the other hand, if subjected to the tax will have an increase in costs relative to the $23 per metric tonne of CO2 emitted. There is also the added cost of administration fees and loss of investment due to higher costs. Other costs that may be included are changes in capital. Pigovian taxes are aimed to have a distortion effect, decreasing the amount of CO2 emitted, changing what firms use to produce and furthermore where future capital investment may be directed (Bruno and Mehmet 2010). Firms from the impact of a Cap and Trade system will be partaking in Coasian Bargaining. This system has been used in the European Union and has shown dramatic decreases in the levels of CO2 by firms (International-Emissions-Trading-Association 2011). Due to the nature of the market, firms will bid and enter a price war against each other that will drive firms to have the lowest operating cost to save on purchasing permits. Firms that do not use the entire permit’s quota are able to bid off their remaining excess to firms whom can afford to pollute, or can’t afford to innovate into cleaner methods of production. Production, if the firm is pollutant dependant will be affected due to a rise in fixed and variable costs and may decrease output (Gilbert 2007). If the firm is not heavily reliant on pollution, it will see increases in its profits due to the revenue gained from trading the permits. The Cap and Trade system promotes production efficiency according to Gilbert Metcalfe’s proposal for a US Cap Swap in those methods that reduce CO2 output cost less via the tariffs placed. The Cap and Trade system from a household’s perspective will be similar to that of the carbon tax, however a time lag may be present due to firms having a time period in which they can allocate their pollution as opposed to an indirect tax. Each policy suggestion from an economic perspective has its own merits and weaknesses and need to be considered when creating a policy that affects both households and firms. The policy must be fair, equitable and efficient to all parties involved. By comparing the implemented Carbon Tax with the feasible alternative, the Cap and Trade system, the different viewpoints of firms and households are understood.

Type I vs. Type II Errors in Hypothesis Testing

Type I vs. Type II Errors in Hypothesis Testing The statistical practice of hypothesis testing is widespread not only in statistics but also throughout the natural and social sciences. When we conduct a hypothesis test there a couple of things that could go wrong. There are two kinds of errors, which by design cannot be avoided, and we must be aware that these errors exist. The errors are given the quite pedestrian names of type I and type II errors. What are type I and type II errors, and how we distinguish between them?  Briefly: Type I errors happen when we reject a true null hypothesisType II errors happen when we fail to reject a false null hypothesis We will explore more background behind these types of errors with the goal of understanding these statements. Hypothesis Testing The process of hypothesis testing can seem to be quite varied with a multitude of test statistics. But the general process is the same. Hypothesis testing involves the statement of a null hypothesis and the selection of a level of significance. The null hypothesis is either true or false and represents the default claim for a treatment or procedure. For example, when examining the effectiveness of a drug, the null hypothesis would be that the drug has no effect on a disease. After formulating the null hypothesis and choosing a level of significance, we acquire data through observation. Statistical calculations tell us whether or not we should reject the null hypothesis. In an ideal world, we would always reject the null hypothesis when it is false, and we would not reject the null hypothesis when it is indeed true. But there are two other scenarios that are possible, each of which will result in an error. Type I Error The first kind of error that is possible involves the rejection of a null hypothesis that is actually true. This kind of error is called a type I error and is sometimes called an error of the first kind. Type I errors are equivalent to false positives. Let’s go back to the example of a drug being used to treat a disease. If we reject the null hypothesis in this situation, then our claim is that the drug does, in fact, have some effect on a disease. But if the null hypothesis is true, then, in reality, the drug does not combat the disease at all. The drug is falsely claimed to have a positive effect on a disease. Type I errors can be controlled. The value of alpha, which is related to the level of significance that we selected has a direct bearing on type I errors. Alpha is the maximum probability that we have a type I error. For a 95% confidence level, the value of alpha is 0.05. This means that there is a 5% probability that we will reject a true null hypothesis. In the long run, one out of every twenty hypothesis tests that we perform at this level will result in a type I error. Type II Error The other kind of error that is possible occurs when we do not reject a null hypothesis that is false. This sort of error is called a type II error and is also referred to as an error of the second kind. Type II errors are equivalent to false negatives. If we think back again to the scenario in which we are testing a drug, what would a type II error look like? A type II error would occur if we accepted that the drug had no effect on a disease, but in reality, it did. The probability of a type II error is given by the Greek letter beta. This number is related to the power or sensitivity of the hypothesis test, denoted by 1 – beta. How to Avoid Errors Type I and type II errors are part of the process of hypothesis testing. Although the errors cannot be completely eliminated, we can minimize one type of error. Typically when we try to decrease the probability one type of error, the probability for the other type increases. We could decrease the value of alpha from 0.05 to 0.01, corresponding to a 99% level of confidence. However, if everything else remains the same, then the probability of a type II error will nearly always increase. Many times the real world application of our hypothesis test will determine if we are more accepting of type I or type II errors. This will then be used when we design our statistical experiment.

Napoleons Fascism Essays

Napoleons Fascism Essays Napoleons Fascism Essay Napoleons Fascism Essay Mussolini had a darwinistic view on life and the struggle of existence. His definition of fascism greatly represents that view and opens up new ideas of life being a duty to serve specific purposes. Mussolini describes fascism as a rule that does not give the majority the right to regulate itself, it believes in heroism and holiness, the rule of divine leaders. Also, he describes that the majority is not capable of ruling, and that nobles are elected through meeting a degree of courage. He explains that there are extreme inequalities in the general public and that political equality, indefinite progress and happiness are all myths. Mussolini viewed the Fascist party as an â€Å"ethic† state, giving it personality, viewing it as an almost divine power. Lastly, Mussolini states the importance of a strong military and dedicated peoples ready to sacrifice for their nation. He emphasizes how disciplined peoples with a strong sense of duty create a stable and orderly nation. His obsession with war lead to the expansion of mass society and leveled social classes. According to Mussolini, his creation of fascism completely rejects ideas of peace and instead to looks to war and sacrifice as the deciding factor between true nobles and cowards. He states that pacifism is an act of cowardice and that war brings forth all human strength and distinguishes between the weak and the dignified. Mussolini explains that fascism views life as a struggle and conquest, furthering his darwinistic views. Mussolini’s claims to restore regulation and use of propaganda fueled people’s hopes in his leadership and promise of order, even if that meant a war-like order. These promises led to Mussolini’s popularity in the first years of his rule due to the people of Italy who were dissatisfied with the anarchy that surrounded them and seemed to believe in any person who promised a restoration of order. In his definition, Mussolini describes that there are great inequalities in the general public as well as in politics. He states that these inequalities are a sort of necessary evil that distinguish between social classes. He also believes that the inequalities in mankind can never â€Å"be permanently leveled† through processes such as universal suffrage and that such processes shouldn’t be put into place because inequalities are beneficial to society as a whole. Mussolini also states that the war between the classes will not be the leading force behind change but should be seen as a beneficial conflict that may bring about order. Through making statements like this, Mussolini was giving the public his truths instead of fabricating his ideas. Mussolini also used traditional values and appreciation of religious beliefs to keep his people united, rich or poor, peasant or worker. In return for his strong sense of values and understanding what role the church played in education as well as in family policy that he portrayed, Mussolini gained acceptance for his fascist tactics from the church who had prior to criticized his policies. This approval from the church furthered his acceptance and popularity from the general public. Mussolini’s separation of the social classes in fact did the opposite and leveled them in society as well as on the battlefield. In the definition, fascism is described as a rule that represents solely the people of Italy, whom were gaining power and again rising after a downfall. Mussolini explains that a great nation demands discipline as well as a sense of sacrifice and duty. He states in what ways militarized politics are beneficial to a society and how total dedication to ones nation is an absolute necessary in maintaining a powerful state. This is evident in his making criticism of the state a criminal offense which in turn led to his wiping out of any parliamentary opposition. Mussolini’s attacks on newspaper offices and striking workers were brutal yet gave Italians a sense of order in their country. He explains in what ways a Fascist state leaves some freedoms to its people yet maintains a sense of organization and that an undisciplined nation is useless and harms freedom. He also states that the individual is not the deciding factor but the state is. Statements as such may have shown the people of Italy that they were being oppressed, leading to revolution. Mussolini made his militaristic approaches and authoritarian advances look appealing to his people which in turn lead to a sequence of disastrous events following the war. These events included economic downfalls and strikes throughout Europe, racism, and a surge to global imperialism. Mussolini viewed peace as an undesirable illusion and pacifism as an act of cowardice. These views gave rise to his state power and advocates both inside and out of Italy. Mussolini’s first followers were drawn in by his militaristic rule and his promise of a divine like military. His war obsession drew in veterans as well as the unemployed by promising them a sense of nobility through their sacrifice. In his definition, Mussolini explains the importance of an obedient and sacrificial nation, ready to battle for their country. His rejection of ideas like peace and pacifism gave his followers a sense of an orderly nation, which was greatly needed during that time. Mussolini’s explanation of the separation of social classes as a necessity and something that may create change in the nation. For this reason, Mussolini states that the majority is incapable of ruling itself, and that noble rulers among himself will come forth to create an orderly nation.

What Critical Thinking Is and How to Develop It

What Critical Thinking Is and How to Develop It The concept of critical thinking has been defined in many complex ways, but for young students new to the concept, it can best be summed up as thinking and judging for yourself. When you develop critical thinking skills, you will learn to evaluate information that you hear and process information that you collect while recognizing your implicit biases. You will analyze the evidence that is presented to you in order to make sure it is sound. Recognize Common Fallacies Fallacies are tricks of logic, and understanding them is the best way to avoid falling for them. There are many types of fallacies, and the more you think about them, the more readily you will recognize them all around you, especially in advertisements, arguments, and political discussions. Bandwagon Appeals: Bandwagon appeals argue that you should follow along with something because everyone else believes it.Scare Tactics: A scare tactic is the use of a  scary story as an example to make you more likely to believe some underlying assumption.Appeal to Emotion: An appeal to emotion uses a fiery speech or a tragic story to convince someone to side with you.False Dichotomy: Often there are many sides to an argument, but a false dichotomy presents an issue as one side versus the other. Characteristics of Critical Thinking To become a critical thinker, you must develop a few skills. Recognize assumptions you carry with you. Have you ever wondered why you believe the things that you believe? Do you believe things because you’ve been told to believe them? Step outside your own beliefs to observe from a neutral viewpoint. Be aware of assumptions and learn to self-reflect.Process information honestly. People sometimes pass along information that is not really true (i.e. the fake news crisis).Recognize a generalization. Girls don’t like bugs. Old people are wise. Cats make better pets. These are generalizations. They’re not always true, are they?Evaluate old information and new ideas. There was a time when doctors thought leeches could cure us. Recognize that just because something is commonly accepted, doesnt mean it is true.Produce new ideas based on sound evidence. Detectives solve crimes by collecting bits of truths and putting them all together like a puzzle. One small deceit can jeopardize an investigation. The entire truth-seeking process is destabilized by one piece of bad evidence, leading to a wrong conclusion. Analyze a problem and recognize the complex parts. A mechanic must understand how an entire engine works before s/he can diagnose a problem. Sometimes it is necessary to deconstruct an engine to figure out which part isn’t working. You should approach big problems like this: break them down into smaller parts and observe carefully and deliberately.Use precise vocabulary and communicate with clarity. The truth can be blurred by fuzzy language. It is important to develop your vocabulary so you can communicate truths accurately.Manage emotions in response to a situation or problem. Don’t be fooled by stirred up, emotional plea or angry speech. Stay rational and keep your emotions in check as you encounter new information.Judge your sources. Learn to recognize hidden agendas and bias when you collect information. As students progress from high school into college and graduate school they must develop critical thinking skills in order to carry out research. Students will learn to identify good sources and bad sources, make logical conclusions, and develop new theories.

Enterprise and Entrepreneurial Management Essay - 5

Enterprise and Entrepreneurial Management - Essay Example Moovers and Shakers must focus heavily on internal human resources strategy to ensure that service staff members positively and enthusiastically represent the business brand. Their performances coupled with moderate and competitive pricing will help Moovers and Shakers gain market interest and achieve better profitability. Moovers and Shakers 1. Introduction Moovers and Shakers is a small, mobile food service business that will be serving Coventry, the 12th largest city in the UK maintaining a population of 316,900 as of 2011 (Coventry City Council 2012). Coventry maintains a diverse variety of different commercial centres, stadiums for sporting events, and five colleges and universities that will assist in sustaining profit for the business. Moovers and Shakers will consist of three mobile food carts, staffed in different locations within the boundaries of Coventry operating between the hours of 11am and 8pm, except during special events (e.g. sporting, school functions or arts and drama) in order to capture lunch and dinner crowds; especially commercial professional customers. Moovers and Shakers will carry a limited, yet targeted menu consisting of hamburgers, gourmet franks, nachos and cheese, pretzels and accompanying frozen and fountain soft drinks. What makes Moovers and Shakers so extraordinary will be the moderate pricing structure and an emphasis on food serving flair provided by recruited operators (staff) to make the Moovers and Shakers dining a complete and interesting experience. Moovers and Shakers will be established as a sole trader organisation. This structure will provide the owner with more control over the business, ranging from administration to accounting, and this business structure requires much less regulatory restrictions and licensing necessary for a small start-up. The sole trader format also gives the business owner much more control over exit in the event that the business is not achieving expected profitability or in the event of the owner seeking a different business opportunity. This is due to the fact that the sole trader maintains 100 percent liability for the company. Until the business is able to expand, maintaining profit control for a single business owner is necessary to ensure proper wage accumulation without split capital. The key to success for Moovers and Shakers is food quality and variety, however it is the finesse and flamboyance of food preparation by the mobile cart operators that will gain customer interest and build more allegiance to the Moovers and Shakers brand identity. Mobile cart operators will operate the frozen drink machines and accessories much like a high-class bartender, putting on a display for customers during preparation. These expert employees with the skills for food prep panache will perform a variety of tossing and juggling when assembling the customers’ products, giving Moovers and Shakers a rapid reputation for a stylish food experience. As such, the business plan will focus on recruitment and retention needs as employees will be vital to building a positive brand and how to reduce risk of losing qualified, expert employees. The business plan will also rely heavily on advertising in order to compete. The business plan therefore focuses on models of marketing that are known to bring more buyer interest and how Moovers and Shakers intends to apply these lessons to this innovative mobile food business. The

Organisations and Behaviour Essay Example | Topics and Well Written Essays - 2250 words - 1

Organisations and Behaviour - Essay Example There are multiple organisational structures found both in theory and in practice. Some are rigid like public sector organisations while others are flexible like small scale private enterprises. There are many variables that affect the structure of the organisation. They include its size, age, staff, culture, geographical position and legal, commercial, social and technical environment. These factors all help to shape many organisational structures. In the basic categorisation, there are tall and flat structures. Below is the comparison of these two types. Tall Structure Flat Structure Size Usually Large Usually Medium Age Independent Independent Culture & Environment Rigid & Formal Flexible & Less Formal Geographical Position Independent Independent Hierarchy Strong Weak Span of Control Tight Loose Chain of Command Strict Loose Delegation of Authority Formal Informal Workload Reduced – Decentralised Increased Career Growth Well Defined Vague There are some other structures wh ich are combination of these two structures. The matrix structure is an example. It has different units and each one follows the tall structure independently. On the organisational level, all units form flat structure. Many organisational structures are dependent upon functional units therefore they extract the required characteristic from all types of structures. It is important to mention here that every organisation differs from other one in terms of structure. There can be variety in tall and flat structures as well. Organisational Structure of Apple The organisational structure of Apple is quite different from the ones mentioned in the literature and found in the practice. It is more like a wheel where CEO places himself at the centre. All other departments and functional units are spread around him and he the key focal of all. This structure reflects the overall leadership and operational philosophy in which Steve Jobs believed. He gave his executive team a direct access to hi mself. Through close coordination with them, he established trust and involvement. The same practise was adopted down the line and Apple won loyalty of employees. Steve’s successor disagreed with this organisational structure. His management and leadership approach is quite different from that of Steve. It is more likely that the command of Tim Cook will transform Apple into an organisational having traditional tall structure. The CEP will be at the top while the Executive Team will be next in the hierarchy and reporting to him. Since the structure is the overall design of an organisation, the functional units of Apple will become tall too. In addition to the conventional pros and cons attached with the tall structure, it is also expected that structural transformation will bring certain resistance. It is because change is naturally resisted and the employees of Apple are used to the wheel structure since long. It is also possible that command of authority may be challenged b y the employees and Apple may not expect the same performance as it was in Steve’s time. Comparison of Organisational Cultures The organisational structure influences the organisational culture. The rigid structure promotes strict and formal culture while the flexible structure is more likely seen in an informal culture. Below is the comparison of formal and informal culture that can exist in any organisation. In formal culture, the basic guideline followed throughout the

Periodic release of updates to existing products and new product development has played a vital role in the

ShutterFly's ProGrowth and ProProfit Essay Example | Topics and Well Written Essays - 1250 words

ShutterFly's ProGrowth and ProProfit - Essay Example Shutterfly has had great commercial successes and fulfilled 12 million orders, sold 370 million prints, stored one billion consumer photos and their net revenues increased from $31.4 million in 2003 to $54.5 million to 2004 and $83.9 million in 2005. Shutterfly was also voted one among the top 500 fastest growing private companies in 2005. The company also got publicly enlisted and offered about 23.5 million shares of common stock. Shutterfly rides on the growth of the photo industry market that allows online consumers to store, share, print and edit photos for the present and future generations. User friendly websites and increased access to the internet have been increasing the number of online photography users and photo prints have been generating revenue of $10 billion in 2005. Greeting cards, scrapbooks, calendars and other general merchandise on digital photography are some of the other revenue generating consumer products that are sold by the company. However several issues such as branding, competition, innovation and expansion, marketing strategies, profits and growth, market shares, consumer preferences have to b considered to analyse the various orientations to growth or profits. It would be interesting to analyse whether profits or growth of a company should be brought about with two different forms of governance, one for increasing profits and other for increasing growth. Certain firms tend to give equal attention to profits and to growth and may allocate equal amount of resources to bring about profits and growth and costs, quality and time spent on PG and PP efforts would be the same (also in Armstrong and Levesque, 2002). It would be necessary to understand whether the PP and PG efforts of a company are opposed or mutually beneficial. In certain cases, the firm would focus only on increasing profits and in certain cases the focus is on growth. With the focus on both profits and growth, there may be conflicting market ori entations and strategies although this would be an interesting combination to analyse the firm's success. Roper (1999) delineated how strategy choices affect market position and business performance of firms and suggested that a firm's turnover growth and return on assets are weakly related for short-term profits. Roper also states that firm performance also depends strongly on strategy choice, with turnover growth being particularly strategy dependent. Thus turnover growth and general profitability of a company as well as long term growth of a company would be all related to strategy choice. Even in case of Shutterfly's business analysis, the primary importance could be given to the strategy and market choices used by the company. Considering the uses of PG and PP, it would be interesting to note that when both PP and PG are allocated, executed and achieved simultaneously, they would together increase the total value of the firm. When these models are used exclusively, then downturn in the firm's performance can lead to the use of an alternate model so the focus would be on either of the two, the PP model or the PG model and either the profits or the growth of the company would be important. In fact Han (2005) noted that the management of two paradoxical forces such as pro-growth strategy and pro-profit strategy could provide for strategic ambidexterity

Measurement and instruments - Lab Report Example on-chip Hall voltage generator for magnetic sensing, a Schmitt activate to offer switching hysteresis for noise denial, a comparator that amplifies the Hall voltage, and output open collector. An internal regulator is used to offer temperature remunerated supply of voltage for internal circuits and enables a large operating supply choice, When current flows through a piece of metal, the voltage can be measured perpendicular to the flow of current and the voltage should equal zero under no influence of a magnetic field (PopovicÃŒ , 74). When a magnet field is introduced perpendicular to the flow of current a voltage is induced. If you reverse the polarity of the magnet the polarity of the induced voltage will reverse. The operation is ignited when the device is placed in a magnetic field. When the material is placed in a magnetic field, the flux lines of the magnet and exerts a force on the material which is a semiconductor. This leads to deflection of electrons and charges. Movement of charge carries is due to magnetic force that they experience (PopovicÃŒ , 204). When current flows through a piece of metal, the voltage can be measured perpendicular to the flow of current and the voltage should equal zero under no influence of a magnetic field. When a magnet field is introduced perpendicular to the flow of current a voltage is induced. If you reverse the polarity of the magnet the polarity of the induced voltage will reverse. There are distinctive features that the instrument has. The features include low current consumption, 3.5V to 24V DC operation voltage, open-Collector pre-driver, wide operating voltage range, temperature compensation, 50mA maximum sinking output current and reverse polarity protection. This is the Hall Effect named after Edwin Hall who discovered this in 1879. The principle which was used was the basic physical principle underlying the Hall Effect being Lorentz force.

Third paper Essay Example | Topics and Well Written Essays - 1000 words

Third paper - Essay Example This is followed by a request, which shows that the speaker is down and ready to prostrate to her girlfriend as he asks â€Å"Shall I go down and bow, baby?† As a romantic song, the speaker goes on to praise his loved one, using romantic terms, descriptions and repetitions. This is a blues song, which doubles the traditional three lines to six lines in every stanza. The last line is a form of a question and the response is provided at the end of the song in a series of derivative three lines answer. The question repeated is ‘Shall I go down and bow, baby?† and at the end of the song, the speaker appears to have reached the end and resolves to answer his question because the referred and revered ‘baby’ seems to have answered in her acceptance and he derives; Shall I go down and bow, baby? I shall go down and bow, baby I am down and bowing baby Oh baby baby make you stay Baby ah baby oh baby I’m done! The pattern of this song is AbcdeB, AfghiBâ₠¬ ¦ and so on, with the first line and the last lines repeated. This pattern is regular and the blues lyrics have concentrated on the theme of love as the speaker tries to show his affection to his goddess, the valentine. The description of the ‘baby’ by the speaker is marked by repetitions. These repetitions are regular, and they make the rhythm of the song regular. In most of the stanzas, the first line and the last lines are repeated in a regular manner. This harmonizes the regular rhythm of the song. The last two stanzas are the conclusion of the song and the speaker consummates his dream of being granted a favour by his girlfriend as thus: Oh ah oh ah baby baby Baby oh baby stay baby My goddess baby, leave not baby oh baby baby Shall I go down and bow, baby? †¦ Shall I go down and bow, baby? I shall go down and bow, baby I am down and bowing baby Oh baby baby make you stay Baby ah baby oh baby I’m done! In this case, the song is conclusive and the clima x is reached when the instruments adopt the rhythm of the song in a unified manner. At the same time, the speaker is able to express his last passions and emotions for his girlfriend who has accepted his request. This song has a regular sound considering its regular rhythm. Being a romantic blues song, it will require soft beats and a mix of melodies. Therefore, the studio producing the song must refine and produce a soft symphony for the song at the start and at the end. The singer or the lead vocalist must be a man and should have a romantic, soft or mildly broken voice so as to exploit the overall theme of the song. This song should be started by a combination of a violin and a keyboard string tunes. Immediately the lead vocalist picks the first line, other instruments should pick and harmonize but should pause whenever the vocalist is picking the first line in every stanza. Moreover, instrumentation should also be toned down whenever the speaker is picking on the descriptive par ts so that the lead vocalist is above all the instruments. This will ensure the message is passed and the song is entertaining and moving as well. When the song is read in the lyrics, the reader is able to pick musical elements such as the tone of the song, the rhythm of the song and possible beat and meter of the lyrics. For example, the lyrics of this song requires a quadruple beat and regular dynamics in the loudness, volume and softness. On the other hand, if one listens to the song, he or she will notice by hearing, not

Sterilization by Saturated Steam Experiment

Sterilization by Saturated Steam Experiment Nurul Aisha Zainal Abidin Introduction Microorganisms are tiny living cells that inhabit our environment. Most of these microorganisms are harmless, where they do not cause any diseases, hence they are known as non-pathogens (Benowit-West et al., 2009). However, there are some that can cause infections which are termed pathogenic. Certain environments make them necessary that the population of these microorganisms are controlled especially health care facilities, laboratories, food industries, pharmaceutical industries, and more (Hoffman et al., 2004). Sterilisation is an important method to control the microbial population, where it is the process of removing or killing viable microorganisms from equipment or substances. Sterilisation process can be done via several means including heat sterilisation, filtration, chemical sterilisation and radiation sterilisation (Schlegel and Zaborosch, 1993). Among these methods, the most commonly used is heat sterilisation in moist (steam) and dry form as others each have their own disadvantages such as toxic residues, risk of radiation, high cost, and capability of causing physical damage to equipment (Rogers, 2005). Other than heat being used as physical agents for sterilisation, ionising radiation and filtration can also be used. Moist heat (steam) sterilisation uses liquid, heat and pressure to form steam which will kill the microorganisms. This process is recognised for its speed of operation, effectiveness, low risk and cost because steam is only pressurised water in gas phase (Block, 1983). It is known that vegetative cells of most bacteria can be killed within 5-10 minutes at a temperature of 60oC however bacterial spores are thermoduric, where they can survive long exposure to high temperature (Bonewit-West et al., 2009). Thus, steam sterilisation is considered to be effective as it destroys viable microorganisms at 121oC for 15 minutes and prevents them from germinating into bacteria. The high temperature applied denatures the proteins within the bacterial endospores, destroying them (Jha and Ghosha, 2005). Dry heat sterilisation also uses heat to denature the proteins of the bacterial cells. This process involves exposing heat stable solid equipment to a temperature of 160oC for 1-2 hours. However, moist heat is more effective in destroying microorganisms compared to dry heat because water vapour can penetrate into microorganisms more readily than dry air. This heat sterilisation method is done in a metal vessel known as autoclave (Jha and Ghosha, 2005). Another method for sterilisation is tyndallisation which is usually for materials that cannot withstand high temperatures in the autoclave. They are exposed to 100oC heat for 30 minutes to inactivate vegetative cells but not the spores. These spores that survive will germinate to form bacterial cells during incubation at 37oC and then the material being sterilised is again subjected to steam at 100 oC for 30 minutes to kill these bacteria. This cycle is repeated for the next 3 days (Talaro and Talaro, 1993). This experiment was done to determine whether there is a difference between efficacy of heat sterilisation (moist heat and dry) and the requirements necessary for this sterilisation process to be adequate. Aims The aims of this experiment were to understand how a steam sterilizer operates, the role and the importance of having to implement moist heat sterilization process, as well as to identify the basic requirements needed for successful steam sterilization. Materials and Methods As per practical manual from page 56-57 Results Two Thermalog strips were each placed in two Schott bottles; one bottle was tightly capped with no water and the other was loosely capped with water present. Five bottles were prepared and spore strips impregnated with B. Stearothermophilus were placed in bottles 1-4. Some water and paraffin oil was added in bottle 2 and 4 respectively. Schott bottles, bottles 2-4 and a Sterikon plus Bioindicator were sterilised in the autoclave. Thermalog strips were observed after the sterilisation process. 3ml of TSB was added into bottles 1, 2, 3, 5 and the spore strip from bottle 4 was transferred to bottle 5. All the bottles were then incubated. The tables below show the observation made from the experiment. Table 1. The observation of the â€Å"Thermalog† strips in the two Schott bottles with different conditions Table 2. The observation of Sterikon vials with one being sterilized and one without being sterilized Table 3. B. Stearothermophilus spore strips in TSB with different conditions after sterilization and incubation Discussion In the first part of the experiment, steam sterilisation indicator, Thermalog strips are placed in two Schott bottles under different conditions. The tightly capped Schott bottle without any water only had a change of colour within the â€Å"unsafe† zone. This is due to the steam from the steriliser that was not able to enter through the tight cap and reach the Thermalog strip. With no water present in the bottle either, steam could not be produced, giving exposure to dry heat. Hence, complete sterilisation was not achieved as direct contact between the steam and the bottle is needed, alongside its temperature and time parameters (121oC and 15 minutes respectively). In comparison, the loosely capped Schott bottle with added water had a change of colour until the â€Å"safe† zone. Because the Thermalog strip was exposed to moist heat in the form of steam during the sterilisation process, complete sterilisation is achieved. In the second part of the experiment, two Sterikon plus Bioindicator vials are used, which could determine the effectiveness of steam sterilisation. These vials have B. stearothermophilus spores along with a pH indicator in a nutrient-filled broth. Both vials were pink at the beginning of the experiment and incubated for several days. The Bioindicator vial that was put in the steriliser showed no colour change while the vial that was not sterilised turned yellow and only slightly turbid. The sterilised vial had no bacterial growth because the spores did not undergo germination to form bacteria due to successful sterilisation which have completely destroyed all bacterial spores. Therefore, the vial retained its pink colour after incubation. However, the colour change from pink to yellow in the other vial indicates that the spores had germinated into bacteria. This is because the vial was not sterilised, thus the spores were able to grow in a favourable condition, whereby they take up nutrients and produce acid which causes the colour change. These findings show that they are vital for monitoring steam steriliser, ensuring that all spores are properly destroyed. If they are not exposed to its temperature and time parameters, some spores might still survive and germinate. In order to determine that sterilisation process is successful, incubation process is implemented to observe whether these spores could still form new bacteria or whether they really have been destroyed. In the experiment which used strips impregnated with spores of B. stearothermophilus in tryptone soy broth (TSB), bottle 1 appeared to be the most turbid among other bottles, which suggests bacterial growth is sustained. Because bottle 1 was not autoclaved, it did not go through proper sterilisation process prior incubation, thus allowing the spores to germinate from the spore strip. Culturing this unexposed spore strip in bottle 1 therefore acts as a control, as it would not have demonstrated that steam sterilisation was actually successful if bacterial growth was not observed because they could have not been able to germinate at all. Bottle 2, however, shows that steam sterilisation was done successfully as the TSB media does not show any turbidity, thus bacterial spore activity was not there. As mentioned, water was added to bottle 2 before it was tightly capped and put into the autoclave, which evaporated into steam (or moist heat) at a 121oC within the steriliser. The steam formed will then kill the spores directly. Apart from that, bottle 3 was tightly capped and had no water added before it was placed in the autoclave. As a consequence, the moist heat could not possibly have direct contact with the spores to be able to kill them. This meant that the spores were only subjected to dry heat sterilization within the bottle, which clearly showed to be a less effective of a method compared to moist heat sterilisation. Because these spores survived the dry heat sterilisation process, they were able to germinate and form bacterial growth under the favourable conditions during incubation, making the TSB media turbid. If dry heat sterilisation was to be implemented to eradicate spores, a higher temperature would suffice. Furthermore, bottle 5 also showed turbidity to almost the same degree as bottle 3. The spore strip in bottle 5 was initially immersed in paraffin oil in bottle 4, before it was transferred into bottle 5. Other than the tightly capped bottle preventing the moist heat from entering, the o il somewhat acts as a protective barrier for the spores, not even allowing dry heat to have direct contact with the spore strip. Based on these findings, it demonstrates to a certain extent to how the biocidal action of moist and dry heat is different and can be compared. Most importantly, the role and the significance of the requirements needed for each sterilisation method. For moist heat sterilisation, a holding time of 121oC for 15 minutes under a pressure of 101kPa is required. In contrast, dry heat sterilisation needs a holding time of 1-2 hours at a temperature of 160oC (Arora, 2003). Therefore, it can be said that moist heat (steam) can perform faster sterilisation, with higher penetrating power as compared to dry heat (Vasanthakumari, 2007). Furthermore, sterilisation using moist heat is more efficient as it uses a lower temperature for the denaturation of protein and the heat in water is also transferred to substances easily (Greenwood et al., 2007). Hence, it is important to note that for steam to be an ideal sterilant, it must be able to have direct contact with the object (external and internal surface) or substance being sterilised. The reason for this is for its stored energy to be transferred to the object through condensation onto all the surfaces which releases its latent heat. As a result, microorganisms are destroyed. Without this direct steam contact, the sterilisation process would be inadequate (Slatter, 1985). Even so, moist heat sterilisation still has a limitation, where it is not capable of destroying prions in the same way as bacteria and spores. Prions, which are stable self-replicating proteins, are highly infective in the central nervous system tissue and they are highly resistant to heat (Hanlon and Hodges, 2013). Therefore, in order to destroy these prions, dry heat sterilisation may be implemented with a temperature of 200oC. Conclusion Successful and complete steam sterilisation can only be achieved if the material being sterilised have physical contact with moist heat (steam) either from the steriliser or from the water inside the material being vaporised. Without the steam, sterilisation process will not be effective because the dry heat cannot destroy the heat-resistant spores. Furthermore, barriers like oils or fats would also prevent the steam from penetrating. Because there are many interruptions or factors that could influence the efficacy of sterilisation, it is necessary to monitor the process. Thermalog strips can be used to determine if the sterilisation process has met its criteria where the material has been exposed to conditions to be safely sterilised. Sterikon plus Bioindicator vials are also used to monitor whether steam sterilisation has occurred. References Arora, D. R. 2003.Textbook of microbiology. New Delhi: CBS Publishers. Block, S.

My Experience with Domestic Violence Essay -- Personal Narrative Essay

I would shut my eyes because I knew what was coming. And before I shut my eyes, I held my breath, like a swimmer ready to dive into a deep ocean.

Social Order and Animal Consciousness :: Biology Essays Research Papers

Social Order and Animal Consciousness There is nothing new about the uncanny abilities of animals. People have noticed them for centuries. Millions of pet owners and pet trainers today have experienced them personally. But at the same time, many people feel they have to deny these abilities or trivialize them. They are ignored by institutional science. Pets are the animals we know best, but their most surprising and intriguing behavior is treated as of no real interest. Why should this be so, and what about the implications of animal consciousness and intelligence through the behavior observed by those with close relations to animals. One reason for institutional science’s lack of interest is a taboo against taking ‘pets’ seriously. This taboo is not confined to scientist but is a result of the split attitudes to animals expressed in our society as a whole. During working hours we commit ourselves to economic progress fueled by science and technology and based on the mechanistic view of life. This view, dating back to the scientific revolution of the seventeenth century, derives form Renà © Descarte’s theory of the universe as a machine. Though the metaphors have changed (from the brain as a hydraulic machine in Descarte’s time), life is still thought of in terms of machinery. Animals and plants are seen as genetically programmed automata. Meanwhile, back at home, we have our pets. Pets are in a different category from other animals. Pet-keeping is confined to the private, or subjective, realm. Experiences with pets are kept out of the real, or objective, world. There is a huge gulf between companion animals, treated as members of the family, and animals in factory farms and research laboratories. Our relationships with our pets are based on different sets of attitudes, on I-thou relationships rather than I-it approach encouraged by science. Whether in the laboratory or in the field, scientific investigators typically try to avoid emotional connections with the animals they are investigating. They aspire to a detached objectivity. They would therefore be unlikely to encounter the kinds of behavior and apparent consciousness that depend on the close attachment between animals and people. In this realm, animal trainers and pet owners are generally far more knowledgeable and experienced than professional researchers on animal behavior- unless they happen to be pet owners themselves. Consciousness has been found to be one of the hardest things to define and study. The textbook definition of "Consciousness" is the full knowledge of what is in one’s own mind; awareness.

Compare Darwin’s Theory of Evolution to Lamarck’s Essay

There have been many theories explaining evolution. Two of the most well known of these are the Lamarckian theory, which was mostly believed before the Darwinian theory, which is the theory which is believed to have the highest probability of it being the case. In Lamarck’s theory of evolution, he stated that an organism was able to pass on required traits to their offspring. This theory is commonly shown through the giraffe’s evolution to having longer legs and a longer neck. According to Lamarck’s theory, during a bad season when all the vegetation in lower areas (easily reachable by the giraffe with the shorter neck and legs) had gone, the giraffes were forced to stretch their necks, to reach for food on a higher level. These giraffes would then have longer necks and would pass this trait of having a longer neck to their offspring. Lamarck’s theory then states that over time, each generation will pass on their traits of having a longer neck than the previous generation, accounting for the evolution of the giraffe from being an animal with a shorter neck and legs, to one seen today with its long neck and legs. Darwin’s theory relied on a process of natural selection. In his theory, at the start there would have been many giraffes of varying heights, which would be so due to the variations in organisms through the process of sexual reproduction. Darwin stated that all life competes in a struggle to exist. Therefore, during a dry season when there is not as much nutrition available on lower levels for the shorter giraffes, the giraffe’s that are more likely to survive are the ones with the longer necks and legs. The giraffes with the shorter necks and legs would die, disabling them to pass on their genes for the shorter legs and necks, resulting in a new generation of longer necked and legged giraffes. These theories can also be shown using other animals such as the horse. The ancestors of horse were once much smaller than the modern day horse. They had four toes on the front legs and three on the back. These toes were padded so they allowed the horse to easily move through wet ground. As the horse moved out of the forest and swamp areas to the plains its head, neck and legs became longer, allowing faster movement and it adjusted to standing  on only one toe. Lamarck would have said that this change was from the horse changing its traits to match its environment. The horse would have had to struggle to run faster to escape from predators when out in the open, and therefore developed a stronger, body to cope with the need for speed. Darwin’s theory would of course differ to this, saying that the horses that survived were the ones, which were able to run faster. These would have been the horses with the longer legs, and so the genes for the horses with the longer legs would be passed on to the next generations. These theories have been widely believed to be the explanation for the varying species of animals on the earth. It is well known now that the Lamarckian theory is not possible, and therefore the Darwinian theory is the explanation that is believed to be the means of evolution. This, however has not yet been proven, however the probability is very great.

Hobbes and Locke Social Contract Theory Essay

Thomas Hobbes and John Locke are two of the most influential political philosophers of the modern age. Their ideas on political philosophy, among other ideas, have helped shaped the Western World, as we know it. One of the most important theories that the two have both discussed, and written in detail on, is the idea of the social contract. Social Contract Theory is the view that moral and/or political duties depend on a contract that leads to the formation of a civil society. Thomas Hobbes was the first person to come up with the idea of a social contract in his text, Leviathan. As with any concept in history, other political philosophers have used Hobbes’ theory as a stepping-stone. One of those men is John Locke, who presents a very different account of how it is civil society is formed. Although both men have very different accounts on the social contract notion, there are some similarities between the two. Before putting pen to paper Hobbes had a front row seat to a quintessential moment in early English history—the English Civil War. The war was a dispute between King Charles I and his followers, the Monarchists and the Parliamentarians. The Monarchists preferred the traditional authority of the king, while the Parliamentarians demanded more power for Parliament, England’s quasi-democratic institution. Hobbes is somewhere in between the two groups with his own set of views. Hobbes believed that political authority is based on the self-interest of the members of the society, all of who are considered equal. He argued that no single individual had the power to rule over the rest. He also backed the conservative point of view that the sovereign must have absolute authority in order for society to last without disruption. It is in the rejection of the Monarchist point of view, that Hobbes and Locke find their first similarity. Both authors sought out to refute the positions presented by Robert Filmer’s Patriarcha, regarding the issue of the Divine Right of Kings. Filmer believed that God gave absolute authority to the king. Since God gives the power to the king, political society focused on obeying God unconditionally. Although Hobbes did agree that it was necessary for a king to have absolute authority in order to keep the people in line, he believed that authority came from the people living in the community and not God. Locke’s most influential political writings come from his Two Treatises On Government. His First Treatise is focused almost entirely on rejecting Filmer’s theory. Locke is in line with Hobbes in his belief that political authority comes from the consent of the governed. Along with this similarity, both men also agree on the idea that those people in a State of Nature will willingly consent to coming together to form a political society. They also agree on the belief that people would live in fear of each other regardless of their ability to use reason. Human nature allows men to be selfish. All people have the natural right to defend their own life, liberty, health and property. This fear is what leads many people to come together and form a state so that there would be a central authority to protect their life, liberty, health and property of all people within society. Along with creating the outline for the social contract theory, Hobbes was also a major contribution to the idea of the State of Nature, a hypothetical situation used to show how people lived before the establishment of society. In the State of Nature, life was â€Å"solitary, poor, nasty, brutish, and short,† characterized by self-interest and the absence of rights and laws (Hobbes 89). Hobbes believed that man was fundamentally evil and required a central authority to keep them out of the conditions of the state of nature. Locke, on the other hand, saw individuals as exercising moral limits over their actions. In order to answer the question of why the people should be willing to submit to political authority, Hobbes uses the idea of a State of Nature. This is a completely hypothetical situation through which he imagines what life was like for men before the establishment of civil society. In the State of Nature, men are naturally and entirely self interested, resources are limited and there is no power that forces the people to follow the rules of society. Men are also considered equal to one another in that even the strongest man can be killed in his sleep. There is no ability for men to ensure the satisfaction of their needs and desires as humans, and no prolonged systems of cooperation among men. The state of nature is a state of constant fear and distrust, or as Hobbes puts it â€Å"a state of perpetual and unavoidable war† (Hobbes 90). Based on the previous definition of the State of Nature, it would seem that mankind is doomed for eternity. However, hope is not lost. Using the power of reason, they are able to understand the laws of nature, which lead man out of the state of nature and into civil society. A Law of Nature, (Lex Naturalis), is a Precept, or generall rule, found out by reason, by which a man is forbidden to do, that, which is destructive of his life, or taketh away the means of preserving the same; and to omit that, by which he thinketh it may be best preserved. (Hobbes 91) The first rule of nature is to seek peace when others are also willing to follow in the quest for peace, â€Å"That every man, ought to endeavour Peace, as farre as he has hope of obtaining it; and when he cannot obtain it, that he may seek, and use, all helps, and advantages of Warre† (Hobbes 92). In the pages leading up to the natural laws, Hobbes describes what it is that drives us to seek peace. â€Å"The Passions that encline men to Peace, are Feare of Death; Desire of such things as are necessary to commodious living; and a Hope by their Industry to obtain them† (Hobbes 90). These are the things that lead people out of the state of nature and into forming a political society. People want protection of their bodies, property, and commodious living. It is through reason that men are led to the construction of a Social Contract, allowing for a life better then in the State of Nature. The social contract is formed through the establishment of two other contracts. The first contract is that they must agree to establish society by renouncing the rights that they had in the State of Nature. The second is that they must choose a single person, or an assembly of people, that will have the authority to enforce the various parts of the contract. The sovereign has the power to punish those who violate the social contract, which leads people to adjust themselves to the rules of their society. In order to understand the purpose of the Social Contract, Hobbes sets forth a definition of a commonwealth, or civil society: And in him consisteth the Essence of the Commonwealth; which (to define it,) is One Person, of whose Acts a great Multitude, by mutuall Covenants one with another, have made themselves every one the Author, to the end he may use the strength and means of them all, as he shall think expedient, for their Peace and Common Defence. (Locke 121) Without a common power to exercise force, society would be the same as it was while in the State of Nature. The Social Contract is considered to be the fundamental source within society for all that is good, along with being the force that allows us to live well. On the opposite side of the spectrum is another major figure in political philosophy, Locke. Locke’s views are very different from that of Hobbes, besides the fact that Locke uses the State of Nature concept created by Hobbes. For Locke, the State of Nature is a state of complete and perfect liberty to live the best life possible, while being free from interference from others. We must consider what state all men are naturally in, and that is a state of perfect freedom to order their actions and dispose of their possessions and persons as they think fit, within the bounds of the law of nature, without asking leave or depending upon the will of any other man. (Locke 5) In this state of equality no person has any power over any one else—everyone is subjectively equal. â€Å"The state of nature has a law of nature to govern it, which obliges every one; and reason, which is that law, teaches all mankind who will but consult it that, being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions† (Locke 5). The state of nature is not a state of license, or a state of authority, in that individuals have the ability to do whatever they want. Although this society is pre-government, morals guide the laws of nature. God gives the natural laws to commands and us that we do not harm others, since we are all equal in the eyes of God. For Locke, the State of Nature is more like a state of liberty that allows the people to pursue their own interests free from interference. It is considered a peaceful state because of the natural laws and its restrictions on the people. Hobbes saw the State of Nature as being a state of constant war, a drastic change compared to the views presented by Locke. Although Locke’s state is predominantly peaceful, there is potential for a State of War. According to Locke, the State of War starts between two or more people when one person declares war on the other. This is usually done by stealing something from the other, or trying to make another man a slave. Since there is no central power to mediate the dispute and the laws of nature allow for self-defense, people are allowed to kill anyone that brings force against them. Without a force to mediate, the duration of wars is much longer and more brutal. Political societies form when men come together in the State of Nature, and agree to give up their power to punish those who disobey the laws of nature and give that power to a central authority. It is through this that the people consent to the will of the majority. Through leaving the state of nature and forming a society, the people create a â€Å"one body politic under one government† and are thus subjected to the will of that particular â€Å"body† (Locke 55). The only way for one to become part of society is through our own individual consent, meaning we cannot be forced to join the society. By joining a society, people gain a few things that they lacked in the State of Nature. These aspects consist of laws, a judge to settle disputes regarding laws and most importantly an executive power to enforce the law. The executive power is created for the protection of the people, their property and general well being. It is when this protection is non-existent, or the King becomes a tyrant by acting against the interest of the people, that the contract can be thrown away. It is with this that the process of establishing a social contract can begin once again, and also the power. Both Hobbes and Locke agree on the fact that people living in a state of nature will come together to form a contract amongst themselves, which ultimately leads to the establishment of society. Both Hobbes and Locke also agreed that people living in a state of nature would be living in a constant state of fear of one another before society is established. Hobbes has a much darker view of Human Nature, seeing them as inherently evil, while Locke viewed man as being guided by â€Å"rational self-interest† with the ability to self-govern without the Leviathan watching over you. These two figures have helped shape our modern systems of government among many other things.
