These may, or may not, identify with an individual’s sees on their own sexuality, and their convictions about their sexual conduct for the duration of their lives. With respect to myself, I can just relate my own encounters and emotions about sex and sexuality to two of these proposed strategies for comprehension. I likewise concur in part to one of the staying three, yet the others, as I would see it, are basically excessively far a stretch. The clench hand approach introduced in this section is the developmental hypothesis. This example of thought articulates that our inaccessible predecessors and their need to relate sex with physical characteristics of the other gender realized human sexuality. Hypothetically, before, people saw certain qualities of the other gender (for instance, adjusted hips or huge bosoms on ladies,) as an indication of richness. This gave rise to the individual from that society to seek after the blessed individual for regenerative reasons. In present day society, notwithstanding, these generalizations appear to be not as significant. The current cosmopolitan ladies have the body of a fourteen-year-old kid.

Comparative Business Case Studies

Question: Examine about the Comparative Business Case Studies. Answer: Clarification of vegetable value climb The cost of vegetable is controlled by the market request and flexibly. As indicated by law of interest, when cost of the item rises, amount interest for the item expands given other affecting components continuing as before. The law of interest delineates that, when different components staying same, increment in the cost of the item prompts the decline in the amount interest for the item. Then again, law of flexibly says that, makers gracefully more in the market, when cost increments per unit of the item. Request bend shows the value that the buyers are happy to pay per unit of the item. Vegetables are vital useful for individual. Because of common cataclysm like Typhoon, horticultural creation has been fallen definitely. Horticulture is for the most part reliant on atmosphere. Because of loss of creation, vegetable gracefully in the Metro Manila has been fallen. In this manner, for a given interest flexibly has been decreased. Lack in flexibly pushes the cost upward. Figure 1: Effect of tropical storm on vegetable cost (Source: made by creator) The underlying harmony point is at E1, where cost is P1 and vegetable provided in the market is Q1. Creation of vegetable is influenced and lack of gracefully happens in the market. The gracefully bend movements to one side and the new flexibly bend is S2. Thusly, the new balance accomplished where the new flexibly bend cuts the interest bend, which is at point E2. At E2, gracefully of vegetables is scaled down in the market to Q2, which is under Q1 and value climbs at P2. As the interest surpassed the gracefully of vegetable in the market, providers have expanded cost to fulfill the need. 2. a) Hike in college education costs Deregulation of University education costs by government demonstrates decrease in government endowment in advanced education. This choice gives opportunity the Universities to decide the education costs all alone. When there are one of a kind charges in the top positioning Universities inside the nation, understudies pick their preferred college dependent on quality. Understudies likewise get affirmation dependent on their legitimacy. Deregulation of education costs may make the Universities serious players. The goal of the University to climb in education cost is producing income and lessening spending deficiency. Low education cost is a type of endowment to the more extravagant. In this ground, climb in University education cost is advocated. Be that as it may, this choice upsets social value. Higher education costs debilitate the low-salary bunch from getting to post optional training. In this manner, the understudies have a place with families with low pay are more averse to take confirmation in that top positioned University regardless of whether they have merit. This may have negative effect on the nature of study in that University. The choice of the bad habit chancellor to climb education costs is practical in the round of social value, as training should be available similarly to all the segment of the general public. b) Monpoly intensity of QantasLink As QantasLink is the main specialist co-op between the Sydney and Toowoombas Brisbane West Wellcamp Airport, it has imposing business model force in this course. Be that as it may, this imposing business model force is a kind of characteristic syndication, as QantasLink offers support in a huge scope. If there should arise an occurrence of regular imposing business model, normal expense is falling ceaselessly. Subsequently, the firm can give item or administration at an exceptionally low cost. Passage of new firm in this industry would be wasteful. Figure 2: Natural imposing business model (Source: made by creator) In the figure 2, the imposing business model cost is Pm and the amount is Qm. On the off chance that the firm charges the imposing business model value, this will create greatest benefits. There will be a deadweight misfortune by the measure of BEC. In the event that cost is set comparing normal or negligible cost, benefit of the firm lessen. Along these lines, government endowment is required for supporting the business. Hence, QantasLink sets cost where MR = MC. Business voyager utilizes the course every now and again contrasted with the relaxation explorer. Subsequently, cost separation for two gatherings of clients can assist with expanding income. The organization can charge more significant expense to the business voyagers as peripheral income would be higher for this gathering due to having inelastic interest bend. Figure 3: Price segregation by monopolist (Source: made by creator) Advantages and cost of Qantas and China Eastern partnership Participation among Qantas and China Eastern give ascent of restraining infrastructure power in the carrier business. In this way, so as to expand joint benefit, they can climb in airfare. Figure 4: Pricing strategy and deadweight misfortune in cartel (Source: made by creator) In the above figure, the AEC triangle shows the deadweight or government assistance misfortune as aresult of cartel between two firms. Pc is the opposition value, which is lower than imposing business model cost charged by the intrigue firms. Serious gracefully of administration is more than cartel. As the two firms together produce not exactly serious yield, deadweight misfortune is made and wastefulness in all out creation increments. As the Qantas and China Eastern make intrigue, this would give them noteworthy benefit contrasted with single activity. Both individual and joint benefit would be boosted. Co-activity regularly assists with limiting the danger of business change. Nonetheless, most definitely, the imposing business model makes government assistance misfortune by charging more significant expense and providing less items or administrations. Purchaser needs to follow through on greater expense contrasted with serious circumstance. In this manner, wastefulness increments. Solidness of the cartel relies upon the trust of one another. 4: Introduction This area examines impact of tax assessment on deals of cigarettes. Cigarette is unsafe for human wellbeing. In this way, one method of recuing utilization is tax collection. Request value versatility of cigarette utilization is featured. This article talks about elective strategy for lessening stogie rates. Cigarette charge has blended impact on utilization. In any case, the viability of duty is assessed in this exposition. Conversation On the off chance that the cost of one parcel cigarette is expanded more than $40 after tax assessment, this has quick effect on deals of cigarette. As, value rises essentially, the amount requested for cigarette lessens according to law of interest, when different things stay same (Callison and Kaestner 2012). As appeared in figure 5, charge is forced on the offer of per parcel of cigarette. Thusly, charge builds cost by t per parcel. In this manner, the flexibly bend moves upward for a given gracefully (Jha and Peto 2014). The new balance is accomplished at a more significant expense P1 and a lower amount Q1 as deals diminishes. A few shoppers of cigarette are forgotten about from the market because of more significant expense of cigarette. They either may diminish their utilization of cigarette or may move to different substitutes (Diaz, Chaloupka and Jernigan 2015). In the event that cigarette is viewed as a typical decent, inconvenience of assessment lessens the deals as utiliza tion diminishes (Abadie, Diamond and Hainmueller 2012). Figure 5: Effect of deals charge (Source: made by creator) Interest for cigarette is inelastic in nature. Increment in cigarette doesn't have a lot of impact on cigarette utilization. Law of interest isn't material successfully for this situation. The dependent individuals proceed with their utilization considerably after increment in cigarette value (DeCicca, Kenkel and Liu 2013). At the point when government forces a business charge on cigarette, the dealers pass the impact of expense onto the shoppers by lessening gracefully. The maker has no additional expense in any case, the customers borne the expanded cost if utilization stays same. There are scarcely any shoppers, who decrease the utilization to set aside cash (Tauras et al. 2016). Least value law or value floor strategy of government forces trouble on vender by limiting them selling cost beneath the base cost. Value floor is named as essential expense to the entire dealer and retailer of cigarette. Cost floor expands cost of working together (DeCicca, Kenkel and Liu 2013). Figure 6: Price floor in cigarette advertise (Source: made by creator) As the above figure portrays that, the value floor is Pf, which is more than the market balance cost. At Pf, the flexibly of cigarette is more than its interest. Along these lines, overabundance gracefully is made in the market (Harding, Leibtag and Lovenheim 2012). At this value, makers decrease their creation of cigarette so as to clear the market. Thus, there will be underproduction in the market (Tang, Tang and Posner 2013). Underproduction makes deadweight misfortune in the economy by diminishing some piece of both the customer and maker overflow. Aside from the cost floor, there are numerous other elective methods of diminishing deals of cigarette, for example, increment in authorizing expenses of tobacco retail and restricting multipack limiting offer (Holford et al. 2014). Increment in permitting influences the retail cost of cigarette pack and may decrease the quantity of retailer. In the perspective on Brown et al. (2014), increment in charge on cigarette pack decreases smoking conduct among the youthful and individual with low financial status. Be that as it may, as cigarette request is inelastic in nature, increment in cost doesn't diminish the cigarette request a lot (Schenk, Thuronyi and Cui 2015). As per World Bank report, tobacco utilization is expanding among the men in low and center salary nations and among the ladies contrasted with the men in the high-pay nations (web.worldbank.org, 2016). There is little effect of expense on the dependent and long haul cigarette smoker. They react gradually to the climb in cost of cigarette (Chiou and Muehlegger 2014). Be that as it may, number of smoker, who is kids and young people, lessens, as they have no wellspring of salary. Moreover, the cigarette smokers have inadequate data about the danger of tobacco utilization. Consequently, number of smoker is more averse to lessen considerably after tax assessment. End The paper features various parts of tax collection on cigarette. As indicated by the interest gracefully m

Know Your Credit Score Amounts Owed

Know Your Credit Score Amounts Owed Know Your Credit Score: Amounts Owed Know Your Credit Score: Amounts OwedIn this five-part blog series, well break down the different categories of information that make up your credit score, starting with your amounts owed.Your credit score: It’s important. It’s how lenders decide if they’re going to lend you money, and at what rates. And remaining in the dark about your score  is the perfect way to end up at the mercy of predatory payday loans and title loans.So how is your credit score determined? As it turns out, there are five categories of information that go into it: payment history, amounts owed, length of credit history, credit mix, and recent credit inquiries. We’re going through them one by one.Today, we’re talking about your amounts owed, which makes up 30 percent of your score.What is  amounts owed?Simply put, your amounts owed is, well, the amount of money that owe on your various debts, including personal loans, lines of credit, and credit cards. In order to figure out your amounts owed, all you need to do it tally up all the outstanding balances on your loans and credit cards.With amounts owed, owing less debt is generally considered a better thing than owing more. The only exception to this is if you never use any debt at all: no installment loans, no credit cards, nothing. That can leave you with a thin credit history that will hurt your score.Beyond keeping your debts to a minimumavoiding large outstanding balances and/or paying down the balances you have already built upthere’s another factor with your amounts owed that needs to be reckoned with.It’s your credit utilization.What is credit utilization?Your credit utilization refers to the percentage of your available credit that you’re using. This won’t matter with your loans, which are issued to you as a single lump sum, but it’ll matter big time with your credit cards.With credit cards, you are given a credit limit that you can borrow up to. The more money you borrow, the more of your available credit you†™re using, and the higher your credit utilization ratio rises.Credit utilization is also where your amounts owed can start to get a bit tricky.30 for (keeping it under) 30“Lenders want you to keep your utilization rate at or below 30 percent,” certified financial educator Maggie Germano (@MaggieGermano) told us. “This means that you should keep your balances below 30 percent of your actual credit limit.”“Say you only have one credit card with a limit of $1,000, but every month you end up spending at least $750. That means that your credit card utilization is typically at 75 percent. One way to improve this is to make sure you pay off your balances in full each month.”Paying down your balances is always a good idea because it also keeps you from accruing interest on the purchases you’ve made. The less you have to spend in interest, the more money you’ll have free to put towards things like emergency funds, 401k’s, or sweet dirt bikes.“If thats harder for you, cons ider asking for a credit limit increase,” says Germano. “This will only help you if you dont increase your spending, though! Keep your spending down, even if your limit is higher.”Let’s use Maggie’s previous example: If you spend $750 against a $1,000 limit, you’re utilizing 75 percent of your available credit. But if you get your limit raised to $2,000, then that $750 is only utilizing 37.5 percent of your available credit. You’ve improved your credit utilization without changing your spending habits at all!Like we said, it gets kind of trickySeven percent and zero percentIf you are committed to paying down your credit card and loan balances, you will see improvements in your credit score. (This is assuming that you don’t start paying all your bills late or hurting your score in some other way.) And once you get your open balances to a 30 percent utilization rate, that should help your score even more.But if utilizing 30 percent of your available credit is good, is there a more specific number that’s ideal? According to nationally recognized credit expert Jeanne Kelly (@CreditScoop) When you review people who have 800 scores, they use only seven percent of what is available to them.”For people who have lots of credit card debt, a seven percent utilization might sound pretty impossible to achieve, but Kelly has additional advice to help you get there:“If you get balance transfer credit cards to help lower the debt with a 0 percent interest rate, that is the time to truly focus on paying the debt down. Do not close the other account that you just transferred it from. But remember the goal is to not use the cards to build up more debt but to lower it.”Keeping your old accounts open helps your amounts owed because it raises your total available credit. Credit utilization is judged across all your different cards, so having one old card with a completely open credit line can (and likely will) positively affect your score.Paying down your de btIf you are able to qualify for those zero percent balance transfers, it’s best to combine them with a solid plan to pay down your debt. The more debt you can pay down while you’re interest-free, the better.So what’s the best way to do it? There are tons of debt repayment strategies out there, but two of the best are the Debt Snowball and the Debt Avalanche.With the Debt Snowball method, you order all your debts from the smallest balance to the largest. You put all your extra debt repayment funds towards the debt with the lowest balance, making only the minimum payments on all your other debts.Once that first debt is paid off, you take all those funds and you put them towards the next debt, working your way up from smallest balance to largest.Plus, every time you pay a debt off, you add its monthly minimum payment towards your future debts. This way, the money you’re putting towards each subsequent debt gets larger and larger, just like a snowball rolling down the hill.The Debt Avalanche is structured in much the same way, only you order your debts from the highest interest rate to the lowest, then pay off the debt with the highest rate first.To learn more about the Debt Snowball and Debt Avalanche, check out these blog  posts:Want to Get Out of Debt? Then Let It Snow(ball)!Sweep Away Your Debt With a Debt AvalancheWhat else can you do?When it comes to your amounts owed, the simplest advice is also the best: pay down your debts as fast as you can, and then try to avoid taking out lots of debt in the future. The more you stay away from high-interest bad credit loans and no credit check loans, the better!Depending on your situation, a debt consolidation loan might also be a good option to help you lower your interest rates and pay down debt faster.In regards to your credit utilization, Alayna Pehrson, digital marketing strategist for BestCompany.com, (@BestCompanyUSA), has a great strategy for keeping your ratio at 30 percent or below:“One way to impr ove your credit utilization is by keeping track of the amounts you charge your credit card. Going over a 30 percent credit utilization will negatively affect your credit score, therefore, if you set up a way to track how much youre charging to the card, then itll be easier to monitor your utilization and keep it low. You can keep track by setting balance notifications or by creating your own credit journal list.”Pehrson also warns that a credit line increase could result in a hard inquiry showing up on your report. So while it might help your score in the long run, it might cause a smaller rise, or even a small dip, in the short-term.Since your amounts owed is one of the two largest factors of your credit reportfixing your credit utilization is a great way to get your credit score up.Tune in next time, to learn about payment history!Check out the rest of our Know Your Credit Score blog series:Credit ScoresPayment HistoryAmounts OwedLength of Credit HistoryTypes of Credit UsedRecen t Credit InquiriesWhat kinds of questions do you have about your credit score?

Clinical Decision Support System ( Cdss ) - 1863 Words

ABSTRACT Clinical decision support system (CDSS) is a technology application that assists clinicians at the point of care to make clinical decisions for patients with specific conditions. The healthcare is implementing many electronic tools that are aimed at improving health and health care delivery. It is designed to make clinical decisions about patient care. Today technology plays an important role in patient care. It involves a patient, a clinician and computer but most of the work is done by computer. CDS helps the clinician to make decisions. While interacting with the patient the clinician can focus more on entering information on hearing to the patient and considering the information said by the patient. Implementing CDS can effect clinician-patient communication. CDS can help clinician by providing clinical guidelines, reminders, of recommended care, prescribing and diagnostic support. In practice this software can lead to confusion and lack of communication. This technology helps with continuity of care. The aim was to compare the design and implementation of CDSS to compare diagnostic accuracy before and after its implementation in patient care.

The Application of Ethics in Progressive Taxation - Free Essay Example

Sample details Pages: 7 Words: 2219 Downloads: 9 Date added: 2017/06/26 Category Economics Essay Type Argumentative essay Tags: Taxation Essay Did you like this example? The Application of Ethics in Progressive Taxation For many centuries, societies have always judged individuals based on their social class. This social structure permits the society to place an individual or a group in a certain social class based on their economic status. The four social classes include; the upper class, the middle class, the working class, and lastly the poverty class. (Business Dictionary, Social Class) With income, comes tax that is given to the government based on the income earned annually. This leads us to questioning whether it is morally justifiable to tax wealthier individuals and families heavier while taxing the lower income individuals and families at a lower tax bracket. This process of taxation is considered to be â€Å"progressive taxation†. (Investopedia, Progressive Taxation) Progressive taxation is approved by some whereas it is criticized by others. This research paper will reflect upon these two perspectives and also reflect whether taxation aimed at redistributing wealth is morally reasonable. According to John K Roth’s definition of deontological theory in â€Å"Ethics†, he defines deontology to be the determination of whether an action is ethical or unethical according to its intention rather than the consequence of the action. Consequentialism is the determination of whether an action is ethically correct or incorrect through analyzing the consequence of the action rather than the intention. (Roth 315-316, 367-369) During this research paper, Roth’s ethical theories of consequentialism and deontology will be used in order to distinguish whether progressive taxation and the use of taxation to redistribute wealth can be identified as morally or unethically correct. According to the article â€Å"Understanding Attitudes toward Progressive Taxation†, it is believed that the progressive rate structure is one of the most desirable forms of taxation upon many phil osophers, economists, and tax policymakers. Those that believe in progressive taxation have the notion that the higher-income taxpayers should be liable to higher taxes than those of lower income. (Michael, Peggy, Cassie 166,168) According to â€Å"Progressive Taxes† by Joel B. Slemrod, in a progressive taxation scheme; â€Å"one’s tax structure is more progressive than another if its average tax rate rises more rapidly with income.† (Selmrod) According to the deontological theory, the intention of this progressive tax structure is to tax every individual or family according to their income and so it betters the life of many people within the society. The consequence of the tax policy will allow all individuals within the society to live their lives according to their needs. Wealthy individuals will still have enough income to live better than those of lower social classes, making it morally ethical because it’s consequences according to the consequential ist theory is saving many lives from poverty. An experiment was done on four-hundred and sixty underground students that were taking nine introductory courses and two additional tax classes at two large university institutions in different regions in the United States. The students were given different scenarios to each of the tax policies that are used to tax citizens in the United States and this included; regressive, flat, and lastly progressive taxation. (Michael, Peggy, Cassie 169-171) Regressive taxation is the contrary to progressive taxation, in which taxes the lower income people more than the wealthier individuals. (Investopedia, Regressive Tax) Flat tax is the application of the same tax rate among all social classes. (Investopedia, Flat Tax) The results of the experiment concluded that the students preferred progressive taxation over the other two forms of tax policies. Progressive taxation had the higher percentage compared to both flat and regressive taxes. Seventy- nine percent preferred progressive tax rates over flat, whereas seventy-six percent preferred progressive tax rates over regressive. (Michael, Peggy, Cassie 171) This demonstrates that among those that do have a basic knowledge of tax, they believe that progressive taxation is the fairest and the most ethical way of bringing among equality in the society. Those that support progressive taxation believe â€Å"that taxes should be assessed proportionally to income, and that upper-income taxpayers are avoiding paying a proportionate tax and therefore higher taxes on upper-income persons are needed.† (Michael, Peggy, Cassie 185-186) The upper-income taxpayers are avoiding paying their proportion of tax to the government and which leads to a negative intention of not willing to help the society as much. This can be viewed as unethical because deontologists would want the wealthy social classes to be contributing more to help the society attain happiness among the greatest numbe r of people according to Roth’s term of utilitarianism. (Roth 1531) The consequence of unwilling to pay their proportion of tax will lead the society to not progress as much as if they did pay their proportion of tax according to the progressive tax structure, and therefore making it unethical for those wealthy individuals to avoid paying their proportion of tax. Progressive taxation helps the government apply â€Å"Income redistribution† to better the society. Income redistribution is the series of actions which takes income from some individuals within the society and redistributes it to others. By collecting taxes, fees, subsidies and granted social benefits, it permits the government to enact this social benefit of income redistribution. Governments also collect taxes, to finance state institutions which benefit in the help to better facilitate the social and economic life of communities. Progressive taxation helps in the cause of Income Redistribution by taking more from the higher income people to help those individuals and families that are under poverty through allowances, subsidies, public goods and services. The practice of taxing the higher income individuals and families based on their expenses like luxury goods, help the means of redistributing income among the society to adjust the inequality among the individuals in the society. (Radu 228-229) According to deontology, the intention of income redistribution is to bring an equalitarian society by reducing the gap in income between the rich and the poor people. This transfer of income is looking to solve the social class inequality and therefore making it ethical. The consequence of income distribution reduces social tensions and creates equalitarian communities that are more united. It is also allowing the government to help those in economical need through cash transfers, food tickets, and social housing. (Radu, 229-232) This action according to consequentialist is ethical becaus e its consequences are bettering the lives of those that are living in poor conditions and allowing them to live a standard life rather than a harsh one. While some believe that progressive tax structure is morally ethical, there are others that do not believe this tax policy is best for the society. They believe progressive taxation is politically irresponsible because it allows majority of the federal income tax to be contributed by the top one percent of taxpayers in America that amounts to thirty-eight percent of federal income tax, whereas the bottom fifty percent of taxpayers pay a way lower portion of only two point seven percent of income taxes. According to deontologists, progressive taxation would be seen as unethical because the intention of the bottom fifty percent of taxpayers is to act selfishly and depend upon the wealthiest of the society to pay a major portion of federal income tax while only two point seven percent of incomes taxes are paid by them. It is estima ted that forty six point nine percent of workers did not contribute and pay the federal income tax during 2009. This results to a minority of taxpayers that are affected with the increase in tax rate and leads the majority of taxpayers to act rather selfishly and depend upon only the top wealthy people to pay their personal federal income taxes to bring change to the society. This political irresponsibility within this taxing policy, leads to an unjust treatment upon the wealthy people. (Hagopian 23) The consequence according to the consequentialist theory would also be unethical, because the consequence of forty six point nine percent of workers not paying their federal income taxes would lead to inequity among the minority because major portion of the income taxes is being provided by them. The second argument against progressive taxation is the fomenting dissension. In the United States system of government and all of Western nations, the issue and tension between the politica l system and the economic system exists. This tension among both political and economic sphere, leads to the act of disputing over welfare and tax policies. (Hagopian 24) The act of disputing over the welfare and tax policies can be viewed as ethical according to deontology, because the intention is to reduce the built-up pressure among the political and economic system in order to bring positive change. Those whom agree with income redistribution hold the fact that inequality stirs up disagreement and strife. Whereas those against progressive taxation, believe that dissension is still present when progressive tax laws are unfair towards those people whom are being taxed. Therefore, a progressive tax structure will lead to people revolting because of the inequity-based principle that is present in the tax policy according to those against it. (Hagopian 24) According to the consequentialist theory, the act of disputing against the progressive tax structure can be seen as ethical, bec ause it can lead to change within the system like resolving the issue of having more people pay their income taxes rather than having the wealthy social class contribute to mostly all the federal income tax. Acknowledging both sides of the argument towards progressive taxation, I believe that this form of taxation can be both morally ethical and unethical according to deontological and consequentialist theory by Roth, and which makes this taxing structure flawed. This can allow us to create a new doctrine of fairness that can be morally justifiable according to both consequentialists and deontologists. This doctrine is constructed on five basic principles. The first principle includes how the most equitable form of tax system is one that bases its policy on the value of benefits received. (Hagopian 24) According to deontologists, this principle is ethical because the intention to pay taxes to the government is to receive valuable benefits in return that benefit the greatest nu mber of people and brings happiness according to the utilitarianism theory. This policy will lead the government to base this principle on the benefits they provide to the society. The consequence therefore will be positive because the government will try to maximize the benefits they offer to the citizens from the tax they collect from the people. This makes this principle ethical in both terms. The second principle includes how income is perceived to be the â€Å"most equitable measure of the value of benefits† and also the ultimate well-being of an individual. Therefore, taxes should be taken proportionally to the benefits received in return from the government. (Hagopian 24) Based on the deontology theory, the intention of this principle is to bring equality among the society by having the government provide equal benefits from those taxes collected proportionally from each individual, and thus making it ethical. The consequences of the principle will allow each indivi dual to have a good sum of their income for daily living expenses due to the advantage of proportional taxing and can also advantage in the governmental benefits that is provided from the tax collected. This principle rejects the notion of per-capita tax system and applies a tax system of proportion instead. (Hagopian 24-25) The third principle of this doctrine is implying that only â€Å"clear income† should be taxed. By clear income, it means that those under the poverty level are not required to pay taxes because their below the level of subsistence and therefore they could barely pay their living expenses. Whereas those that are above the level of subsistence should pay taxes because they are more than capable in living their lives with adequate surplus of income after all their daily living expenses. (Hagopian 25) Deontologists would believe that this principle is morally justifiable because the intention of this principle is to bring an equalitarian society and help those that are incapable to live by not having them pay taxes. Those that are beyond the level of subsistence should pay their taxes to permit the government to have some form of financing to help the society as a whole. The consequence of this principle is moral because it allows a greater number of people to live a fair life with an adequate sum of income. The fourth principle is how progressive taxation on income is inequitable when it comes to work effort. In an equal playing field, those that have a high-value aptitude generally make more income than those of low-value aptitude. Among each tier of aptitude, includes a â€Å"mini-society† that differentiates income only through the work-effort they put in to making money. Hence, an individual that puts a work effort above the median in his/her tier aptitude will make more than someone that puts a work effort below the median. Although the individual whom is implementing more work effort is making more money, he/she mus t pay more taxes than the person who puts less work effort in the tier of aptitude based on the progressive tax structure. This unfair system according to consequentialist will lead to a great number of people of making less after-tax income per hour than someone else in their tier of aptitude because they worked harder to earn more income. Progressive taxation in this sense is seen as unethical because of its inequity. Don’t waste time!

Shylock meets Mussolini Essay Example For Students

Shylock meets Mussolini Essay Stenciled on a Venetian building are a pair of faces one black, one white. A sword slices between the heads. La Difesa de la Razza (The Defense of the Race) reads the terse legend. Welcome to 1937 Italy, the apex of Mussolinis power and the setting for the California Shakespeare Festivals season-opening production of The Merchant of Venice, running through Aug. 20. Although the Holocaust is never directly referred to, the audience is well aware of both the imminent passage of Il Duces virulent anti-Jewish laws and the eventual Nazi-inspired campaign of genocide. You cant help but approach this play without considering anti-Semitism in the 20th century, director Michael Addison declares. As a directory you hope you create a millieu that is expansive enough to let us reach back into our own cultural history. Now in his sixth season as the theatres artistic director, Addison interprets The Merchant of Venice as a multi-dimensional clash between tradition and modernity, the past and the future. The lovers, Portia and Bassanio, are juxtaposed with the established order that arbitrates the disposition of Shylock and Antonios sloan. The staid rituals of Belmont, meanwhile, contrast with the libidinous parties of Venice. It is a theme repeated throughout Shakespeares comedies, Addison asserts, namely how humankind manages to find a balance between youthful energies that want to spend themselves freely and uninhibitedly and the impulse of older people to husband resources. The notion of social upheaval has a visceral effect when transposed to the rupture of Italian society and the world in the late 1930s. The theft of Shylocks daughter and jewels evokes more than age-old anti-Semitism; in this context, the Jews merciless yet entirely legal efforts to extract his pound of flesh from his debtor (who once spat on him in public) can be readily understood. In a flash, Shylock is transformed from an anti-Semitic caricature of a greedy Jew into a man whose life and family are threatened with destruction. Last seasons Oregon Shakespeare Festival production of Merchant was prominently criticized by an Orthodox Jewish educator, but Addison does not anticipate the slightest controversy over his portrayal of Shylock in this staging. There may be some in the Jewish community who think the play reinforces stereotypes, he acknowledges, no matter how human you make Shylock and no matter how much cause you give to his atavistic behavior. Citing Shylocks love and concern for his daughter, his erudition, wit and sense of humor, Addison contends that Shylock is a well-rounded character, radically different from other villains of the period. It isnt until his daughter is stolen that he becomes monomaniacal. Whether Shakespeare was an anti-Semite or wrote a play to lead people away from anti-Semitism is an open question. The director never forgets that Merchant is one of the Bards comedies, although he maintains that the comic action doesnt mean anything unless its severely threatened. In finding the balance between light and darkness, Addison recognizes that the plays contrasting moods are one of its assets. I hope the comedy will be strengthened by having a social reality to operate within, he declares. Any play that deals in a significant way with racism and social dissolution is appropriate now.

A Timeline of Events in Electromagnetism

A Timeline of Events in Electromagnetism Human fascination with electromagnetism, the interaction of electric currents and magnetic fields, dates back to the dawn of time with the human observation of lightning and other unexplainable occurrences, such as electric fish and eels. Humans knew there was a phenomenon, but it remained shrouded in mysticism until the 1600s when scientists began digging deeper into theory. This timeline of events about the discovery and research leading to our modern understanding of electromagnetism demonstrates how scientists, inventors, and theorists worked together to advance the science collectively. 600 BCE: Sparking Amber in Ancient Greece The earliest writings about electromagnetism were in 600 BCE, when the ancient Greek philosopher, mathematician and scientist Thales of Miletus described his experiments rubbing animal fur on various substances such as amber. Thales discovered that amber rubbed with fur attracts bits of dust and hairs that create static electricity, and if he rubbed the amber for long enough, he could even get an electric spark to jump. 221–206 BCE: Chinese Lodestone Compass The magnetic compass is an ancient Chinese invention, likely first made in China during the Qin dynasty, from 221 to 206 BCE. The compass used a lodestone, a magnetic oxide, to indicate true north. The underlying concept may not have been understood, but the ability of the compass to point true north was clear. 1600: Gilbert and the Lodestone Toward the late 16th century, the founder of electrical science English scientist William Gilbert published De Magnete in Latin translated as On the Magnet or On the Lodestone. Gilbert was a contemporary of Galileo, who was impressed by Gilberts work. Gilbert undertook a number of careful electrical experiments, in the course of which he discovered that many substances were capable of manifesting electrical properties. Gilbert also discovered that a heated body lost its electricity and that moisture prevented the electrification of all bodies. He also noticed that electrified substances attracted all other substances indiscriminately, whereas a magnet only attracted iron. 1752: Franklins Kite Experiments American founding father Benjamin Franklin is famous for the extremely dangerous experiment he ran, of having his son fly a kite through a storm-threatened sky. A key attached to the kite string sparked and charged a Leyden jar, thus establishing the link between lightning and electricity. Following these experiments, he invented the lightning rod. Franklin discovered there are two kinds of charges, positive and negative: objects with like charges repel one another, and those with unlike charges attract one another. Franklin also documented the conservation of charge, the theory that an isolated system has a constant total charge. 1785: Coulombs Law In 1785, French physicist Charles-Augustin de Coulomb developed Coulombs law, the definition of the electrostatic force of attraction and repulsion. He found that the force exerted between two small electrified bodies is directly proportional to the product of the magnitude of charges and varies inversely to the square of the distance between those charges. Coulombs discovery of the law of inverse squares virtually annexed a large part of the domain of electricity. He also produced important work on the study of friction. 1789: Galvanic Electricity In 1780, Italian professor Luigi Galvani (1737–1790) discovered that electricity from two different metals causes frog legs to twitch. He observed that a frogs muscle, suspended on an iron balustrade by a copper hook passing through its dorsal column, underwent lively convulsions without any extraneous cause. To account for this phenomenon, Galvani assumed that electricity of opposite kinds existed in the nerves and muscles of the frog. Galvani published the results of his discoveries in 1789, together with his hypothesis, which engrossed the attention of the physicists of that time. 1790: Voltaic Electricity Italian physicist, chemist and inventor Alessandro Volta (1745–1827) read of Galvanis research and in his own work discovered that chemicals acting on two dissimilar metals generate electricity without the benefit of a frog. He invented the first electric battery, the voltaic pile battery in 1799. With the pile battery, Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Voltas invention sparked a great deal of scientific excitement, leading others to conduct similar experiments which eventually led to the development of the field of electrochemistry. 1820: Magnetic Fields In 1820, Danish physicist and chemist Hans Christian Oersted (1777–1851) discovered what would become known as Oersteds Law: that an electric current affects a compass needle and creates magnetic fields. He was the first scientist to find the connection between electricity and magnetism. 1821: Amperes Electrodynamics French physicist Andre Marie Ampere (1775–1836) found that wires carrying current produce forces on each other, announcing his theory of electrodynamics in 1821. Amperes theory of electrodynamics states that two parallel portions of a circuit attract one another if the currents in them are flowing in the same direction, and repel one another if the currents flow in the opposite direction. Two portions of circuits crossing one another obliquely attract one another if both the currents flow either towards or from the point of crossing and repel one another if one flows to and the other from that point. When an element of a circuit exerts a force on another element of a circuit, that force always tends to urge the second one in a direction at right angles to its own direction. 1831: Faraday and Electromagnetic Induction English scientist Michael Faraday (1791–1867) at the Royal Society in London developed the idea of an electric field and studied the effect of currents on magnets. His research found that the magnetic field created around a conductor carried a direct current, thereby establishing the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He similarly discovered the principles of electromagnetic induction and diamagnetism and the laws of electrolysis. 1873: Maxwell and the Basis of Electromagnetic Theory James Clerk Maxwell (1831–1879), a Scottish physicist and mathematician, recognized that electromagnetisms processes could be established using mathematics. Maxwell published Treatise on Electricity and Magnetism in 1873 in which he summarizes and synthesizes the discoveries of Coloumb, Oersted, Ampere, Faraday into four mathematical equations. Maxwells equations are used today as the basis of electromagnetic theory. Maxwell predicts the connections of magnetism and electricity leading directly to the prediction of electromagnetic waves. 1885: Hertz and Electric Waves German physicist Heinrich Hertz proved Maxwells electromagnetic wave theory was correct, and in the process, generated and detected electromagnetic waves. Hertz published his work in a book, Electric Waves: Being Researches on the Propagation of Electric Action With Finite Velocity Through Space. The discovery of electromagnetic waves led to the development to the radio. The unit of frequency of the waves measured in cycles per second was named the hertz in his honor. 1895: Marconi and the Radio In 1895, Italian inventor and electrical engineer Guglielmo Marconi put the discovery of electromagnetic waves to practical use by sending messages over long distances using radio signals, also known as the wireless. He was known for his pioneering work on long-distance radio transmission and his development of Marconis law and a radio telegraph system. He is often credited as the inventor of the radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun in recognition of their contributions to the development of wireless telegraphy.

Ethical Perspectives Cross Cultural Perspectives Essay

Ethical Perspectives Cross Cultural Perspectives - Essay Example This includes handling the customers and the services offered by the workers. Culture, however small and ineffective the fact may look like, determines a lot the success of the company (Alice, 2012). This essay focuses the idea of the culture of Wal-Mart store and how its culture has affected the company. Ethics are the upright wellbeing and undertakings of the company. Ethics and social responsibility, also plays a major role in shaping the general business. The essay also addresses the issue of ethics and social responsibility and what is to be done so as to improve the services of Wal-Mart stores. Wal-Mart operates in several countries outside United States. The road in establishing their stores in other countries have not been that smooth. The main reason behind this is due to the cultural conflict with other countries. Wal-Mart is a company based in the United States and the manner in which they conduct their services and the kind of products sold is mainly determined by homeland cultures. When the company ventures in external markets or other countries, it is faced with cultural conflict where the cultures are conflicting. Customers from other countries view the operations from Wal-Mart as inferior to theirs and hence the company loses market from the customers thus reducing the company’s profits and product management (Alice, 2012). It is as well correct to say that Wal-Mart is aggressive in searching for markets for its products and services. When they tried to venture into the Argentina market, the company did not succeed because of its culture. The people of Arg entina did not embrace their products due to conflicting cultures. Wal-Mart also has a culture of exploiting the middle class and enhances gender inequality. In Germany for example, international employees are paid more than the local employees, a situation that lead to the loss of a lot of workers. The cultural issues within the organization also determine the success

Robert Brownings Poetry | Analysis

Robert Brownings Poetry | Analysis Compare the examination of abnormal psychology in Robert Brownings poetry, and in Iain Banks novel, The Wasp Factory. Make illuminating connections with the work of Edgar Allan Poe.   The abnormal mental state of the narrators in both Brownings poetry and in Banks novel, The Wasp Factory, is intrinsic in achieving the gothic style. Whilst the protagonists insanity is more implicit in Brownings poetry, the narrators, nevertheless, display similar characteristics of psychosis and delusion. Indeed, this madness disconnects the characters from the rest of society, and this element of monstrosity is vital in creating the intrigue and terror that ensues. Inclusion of such monstrous figures destabilises the natural order: it challenges the fixed social structures and ideology, and becomes inconsistent with what the majority considers both acceptable and intelligible. Yet, whilst on the surface gothic works may appear to reinforce these seemingly grotesque characteristics, in many respects, through exposing the unnatural, they deconstruct the illogical, and thereby attempt to create a set of social norms. The first chapter of The Wasp Factory, The Sacrifice Poles, serves as a warning to the reader that they are entering into the domain of Franks psyche. The unconventional behaviour she displays is evident through her intentional replacement of common nouns with proper nouns: for instance, the capitalisation of words such as Factory and Poles. Essentially this represents the objects which Frank views as significant in the private world that she has constructed for herself. Franks tendency to fantasise is further demonstrated through the naming of her catapult- The Black Destroyer. In fact, Frank goes beyond symbolism- for instance she assigns the house with humanistic attributes through personification: powerful body buried in the rock. Of course, this description may well be representative of the dark life she lives, in regards to both her social isolation and the sinister lifestyle that she leads. The conflicting behaviour that Frank exhibits, that is her seemingly child-like behavio ur and her meticulosity with rituals, underlines her highly unusual mental state. The initial lines of Porphyrias Lover similarly imply the protagonists unusual frame of mind. The use of pathetic fallacy and personification, for instance, the sullen wind is not only effective in creating a cold and melancholy atmosphere, but may be representative of the narrators mind; consequently, there is a strong sense of foreboding. The abnormal psychology of the narrator is further exemplified through the description of how the wind did its worst to vex the lake. Likewise, the wind is awake and tears down the elm-tops for spite. Thus, the wind is perhaps an emblem of the narrators destructive capacity: it could be argued that the lake is representative of Porphyria, and the wind is representative of the narrators anger towards Porphyria. In this sense, the narrators anger is possibly a consequence of his inability to possess the femininity that Porphyria exudes. The Laboratory also reveals a narrator that exhibits an unstable mental state. The anapaestic meter of the poem po ssibly reflects her enthusiasm and engagement in producing the poison. Additionally, the tricolon Grind away, moisten and mash up thy paste is representative of her increasing exhilaration as the poison approaches completion, whilst active verbs such as grind and pound convey violent connotations, which present us with an ambience of foreboding. The exquisite blue and the gold oozings of the poison, however, are possibly an allusion to the opulence of the French court. There is a stark contrast between the murky laboratory, which is arguably representative of the decadent aristocrats, and the affluence of the court; this is perhaps symbolic of the widespread corruption that encompassed the French aristocracy. During the emergence of the gothic literary movement, history was characterised by widespread political unrest often resulting in revolution. Subsequently, the genre became very popular with writers as it enabled them to express sympathy and moral concern over such movements. I n The Fall of the House of Usher, Poes imagery describing the attrition of the house is perhaps an attempt to symbolise the narrators degenerating mental state. Also, the Haunted Palace that is occupied by evil things (that) assailed the monarchs high estate is possibly an allusion to how his mind is being possessed by the malevolent forces that ostensibly surround the house. In The Wasp Factory, Franks father also displays an abnormal state of mind, which is demonstrated through his efforts to exert constant authority over his daughter. Mr Cauldhame has ultimately left Frank excluded from society through his decision to conceal his identity and home educate him. More sinisterly, however, Angus, through experimentation, has essentially created a contemporary Frankenstein. Fundamentally, Angus has suppressed Franks innate feminine characteristics through experimental hormone therapy and has indoctrinated her with misogynistic views. This enables Mr Cauldhame to think that he is in control of what he views as the correct father- son relationship. Of course, normality has no association with Franks life: the child-like mentality that she exhibits through her fantasy, perhaps signifies that, in reality, Frank is scared of the real world in a multitude of ways. Alternatively, this fantasy world may keep Frank at least partially sane: Eric shows the stark conse quences that may result from the real world. Moreover, their use of imperial measurements is not only indicative of Mr Cauldhames compulsive disorder, but accentuates the concept that the island does not progress with time. In this respect, the Cauldhame family is a microcosm of the demise of the empire and the island is a last remnant of it. Accordingly, it can be argued that it was the demise of Angus position as a patriarch that has ultimately brought about his decision to devise an all male enclave. Angus obsession with control, therefore, stems from his fear of being replaced as the monarch of the empire because of the emergence of the new feminist movement. Thus, Angus Cauldhames behaviour is synonymous to the description found in Jerrold Hodges gothic textbook: Angus has created a patriarchal enclosure designed to contain and even bury a potentially unruly female principle'. The way in which Banks presents the reader with a typical boys story whose protagonist is, in truth, a girl is perhaps a critique of the way in which society devises fixed binary gender stereotypes, and thus is an attempt to undermine these traditional gender expectations. Frank, however, conforms to the typical gothic female character, who is suppressed by a domineering male; the irony is that Frank is both the subjugated female and the tyrannical male. A similar desire for control is displayed by the narrator in Brownings My last Duchess. This element of control, that the narrator wishes to possess over his wife, is exemplified through the poems iambic pentameter. With twenty-eight rhyming couplets, the very tight structure of the poem is possibly representative of the level of authority and control that he expects to exert over his wife. The curtain that he has drawn over his late wifes picture is again perhaps symbolic of the level of authority that he desires to exercise over his female partners. Indeed, he gave commands; Then all smiles stopped together. The underlying sense of threat signifies his expectations of how his wife should behave. Ironically, however, the Duke can only, when his wife is dead, counteract what he perceives as her earnest glance. Fundamentally, his wife has been objectified from subject to object; she is simply one of his possessions. Similarly, the narrator in Porphyrias Lover demonstrates a notion of control. The sibilance in the sentence, she shut the cold out stresses how she is able to alleviate the narrators mental anguish. However, it also stresses the narrators dependency on Porphyria and this concept is reiterated through the way she was mine, mine. The use of repetition thus highlights the possessive nature of the protagonist. Certainly, it is possible that the narrator is resentful of both her social superiority and of her more commanding presence. In the nineteenth century, society was characterised by patriarchal codes, which women had to adhere to; men typically exerted absolute control over their female partners. Thus, Porphrias gay social life may also be a source of the protagonists bitterness and the only way to free himself of such powerlessness is to kill her. Browning may be attempting to indicate a reversal of gender roles; the male is the weak character through his inability to keep control of himself- let alone Porphyria. In this sense, the protagonists obs ession with maintaining control is similar to that displayed by Mr Cauldhame in The Wasp Factory. Franks aggressive behaviour also illuminates her abnormal psychology. In many ways, the buck, which Frank encounters, is symbolic of all the things that she wishes to possess: that is, ironically, an alpha-male persona. This concept of masculinity is maintained through the way that Frank hissed. This animalistic imagery, once again, highlights Franks aggressive and territorial nature, which reveals her very apparent abnormal mindset. In essence, though, this encounter is an externalisation of Franks internal battle. This externalisation of an internal conflict is perhaps representative of Franks struggle with her dual gender identity. Additionally, this attack of revenge on the buck reinforces that Frank has the capability to kill and in fact clarifies her monstrosity. More disturbing, however, is Franks admittance that it felt good; this compounds her mental disposition. This scene provides the reader with a very clear image of Franks ability to inflict suffering and destruction whi lst chillingly deriving pleasure out of it. The externalisation of internal conflicts is equally manifested in Poes work. For instance, in The Tell-Tale Heart and The Black Cat the narrators attempt to bury the corpse symbolises their attempts to conceal the problem. In The Black Cat, the narrators attempt to hide the corpse under the wall is ultimately representative of his desire to contain his problems within. Alas, for the narrators, their failure to deal with their problems effectively, leads to the resurfacing of the initial problem, and, inevitably, their downfall. However, despite Franks seemingly grotesque and in many ways nauseating behaviour, the reader can, nevertheless, sympathise with her. Franks manipulative nature may well be an attempt to expose her abnormal mind further. However, an encounter with this element of monstrosity is sometimes known to provoke paradoxical emotions. This notion of abjection as Julia Kristeva describes is the in-between, the ambiguous, the composite. Thus, the monstrous element has the ability to induce sentiments of horror and desire, disgust and fascination. Indeed, Franks mix of monstrosity and humanity possibly provide us with a forewarning of the transgression of which we may all be capable of; this, of course, presents a poignant and unsettling dimension. The Inclusion of animals is evident in Franks encounter with the buck, and in Poes The Black Cat. Poes story, like Banks novel, perhaps includes these animalistic aspects to reiterate that by undertaking such vicious acts the narrators are in complete deficiency of a logical human psyche, and are more comparable to animals who ultimately do not work within such moral frameworks. The authors are perhaps attempting to demonstrate that the narrators are deficient in human ethics: as philosopher Daniel Dennett states, many regard human ethical knowledge as a marvellous perspective that no other creatures have. The unconventional behaviour displayed by the narrator in Porphrias Lover, is implied further through the way he debated what to do. This uncertainty accentuates that when he kills Porphyria, it is a conscious decision and not an impulsive act. The composure, which the narrator exhibits is also shown through the very orderly ABABB rhyme scheme which is ultimately suggestive of the attitude, albeit this makes him appear all the more dangerous. However, alliteration in the sentence Blushes beneath my burning kiss presents a degree of desire for Porphyria. The paradox may nonetheless simply epitomise his psychosis. In The Wasp Factor, Franks casual admittance that his killings were Just a stage (he) was going through, stress his lack of remorse; in fact, like the narrator in Porphrias Lover, Frank is essentially justifying his actions. Hence, it reveals the very apparent psychosis of both narrators. In addition, despite Brownings clues towards the protagonists madness, it is never evide nt through the tone or diction of the poem. Instead of being presented with a stereotypical mad character, like Eric in The Wasp Factory, it is more implicitly implied. Alternatively, his madness is suggested through what the narrator does not say and the fact that he perceives Porphyria as being happy and at peace: The smiling rosy little head; the narrators portrayal of events can simply not accord with reality. Undoubtedly, the narrative of Porphrias Lover could well be a figment of the protagonists imagination; if this is the case, then it clearly reinforces that the narrator exhibits an element of abnormal psychology. The concept of the narrator justifying their actions is illuminated in The Tell-Tale Heart. The narrator is essentially justifying the murder of the old man through the notion that he had an evil eye: I think it was his eye!- yes, it was this! In essence, the narrators uncertainty alludes to the concept that it is simply an attempt to justify the sinister and irra tional behaviour that the reader is about to witness. A parallel can be drawn between the way in which the narrators justify their behaviour and the notion of self-deception. In The Wasp Factory, Franks self-deception is exemplified through the way in which she has essentially created her own fantasy. Franks propensity to self-deceit is apparent through the final chapter: the factory was my attempt to construct life, to replace the involvement which otherwise I did not want. Moreover, the level of deception is explicitly expressed through her engagement in rituals, which is an attempt to affirm her position as man. Franks repetition of the secret catechisms thus helps her to create the illusion of her male persona. Ultimately, though, her attempts are futile: the juxtaposition of the bowie knife and comb that Frank carries around presents the reader with a subtle intrusion of Franks real gender identity. These two contrasting objects possibly symbolise Franks conflicting personality: the knife is representative of the destructive behavi our that she asserts to conform to her male persona, whilst the comb is representative of her inherent, albeit more restrained, feminine character. This lingering uncertainty regarding sexual identity, as Boris Kà ¼hne argues, is a source of the uncanny and presents us with a pervasive gothic feeling; this ostracises Frank from societal norms and is inevitably the major source of her monstrosity. This is also evident in Brownings Soliloquy of the Spanish Cloister. Essentially, the narrator soliloquises his own inadequacies and attributes them to Brother Lawrence. Stanza four illustrates the narrators perception of his own self-righteousness, and indeed his dedication to denouncing Brother Lawrences commitment to his faith. The narrator describes Brother Lawrences ostensible lusting over the two nuns, Dolores and Sanchicha. Yet he goes on to explain that that is, if hed let it show; crucially, there is no evidence that Brother Lawrence has been looking at the nuns lecherously. Rather, the detailed account of the nuns activities must be a product of the narrators own impure thoughts, and his attempts to attribute these unchastely thoughts to Brother Lawrence can only serve to accentuate his self-deceptive and manipulative personality. The monks attempt to describe himself as the epitome of morality continues with his comment regarding the symbolic divide between their table eti quette. The crossing of his silverware, the narrator argues, symbolises his remembrance of Christs death on the cross; Brother Lawrence displays no such gesture. Additionally, the narrators absurd suggestion that Brother Lawrences drinking of the watered orange pulp in three sips supposedly denies the Arian doctrine again provides us with an illustration of his attempt to reaffirm his moral superiority. Ironically, despite the narrators belief, his attempt to condemn Brother Lawrence into eternal damnation reiterates his spiritual inferiority; this irrational behaviour provides an indication that Brownings narrator also exhibits an elementary characteristic of abnormal psychology. The quasi-religion that Frank constructs evidences the depth of her delusion and, correspondingly, her abnormal psychology. However, Franks religion has not stemmed from an intrinsic religious belief, but arguably out of a necessity to harbour some control, whilst denying any element of responsibility. Frank, in light of the failure of familial relationships, relies on The Wasp Factory to guide and ironically protect her. Frank creates a polytheistic religion: water, fire and death are all pseudo-Gods and perhaps compose Franks trinity. Indeed, Franks monstrosity is a result of her moral indifference. Since sea has destroyed what (she has) built wiping clean the marks (she) made Frank perhaps deduces that this permits her to inflict suffering on animals, which are below the pseudo-hierarchical order that she has constructed. However, the contrast to the sea destroying her dams and the sadistic killing of the rabbit is not apparent to Frank. Franks quasi-religion naturally has many Ch ristian elements: the lighting of the candles in Franks religions, nevertheless, contrastingly symbolises a destructive power. Banks notes that this was an attempt to satirise religion, and expose the ways in which we are all deceived, misled and harking back to something that never existed. Consequently, Banks ridicules all religions perhaps in a bid to create a society that is free from religious doctrine, and one that advocates logic and equality. Poes work also contains religious undertones. For instance, in The Tell-Tale Heart, the narrator essentially ascribes himself the role of God; this is reinforced by the way he describes the extent of my powers- of my sagacity. The delusion of grandeur ultimately reveals his damaged psychological state. Religious overtones are similarly apparent in Porphyrias Love. The imagery arguably possibly portrays Porphyria as an angelic entity. The way she glided in and her ability to make the cottage warm suggest a supernatural quality, with her yellow hair and bare white shoulder possibly alluding to her angelic purity; even when Porphyria is dead, the narrator describes her blue eyes without a stain. The presentation of Porphyrias purity and innocence may well be an attempt by Browning to accentuate a feeling of anguish after Porphyrias death. Conversely, the magical element that the narrator has ascribed to her may ultimately be a result of the magic in his head. In this respect, the reference to her eyes, which were without a stain, is perhaps his warped perception that Porphyria worshipped him; after all, the eyes are a window to the soul. Certainly, the notion that she worshipped him is reinforced by his absurd insistence that she is happy and at peace in his arms: the smiling rosy lit tle head. The fact that God has not said a word, however, is perhaps a direct attack on God: a sin has been committed yet no justice has been obtained. Indeed, Brownings poem was written during the Age of Enlightenment, a time where the legitimacy of the Bible was challenged and an emphasis of rationalism over religion occurred. In a rather different perspective, the God which is referenced may simply be a rhetorical God, which the narrator uses to convey his perception of how any God across all religious spectrums would view the strangulation of Porphyria as morally correct; this would clearly reinforce that the narrator exhibits an abnormal mental state. To conclude, all the texts examined contain quintessential characteristics of gothic mode and symbolism, which disclose the abnormal psychology of the narrators. The monstrous aspect pervades us with a feeling of uneasiness and revulsion. Yet, through including the seemingly grotesque and disconnected narrators, the gothic is able to defuse the transgressive, and challenge the conventional expectations of society. In The Wasp Factory, Banks perhaps attempts to satirise the way in which society constructs binary gender stereotypes and, in doing so, challenges what appears to be an illogical social norm. Similarly, Brownings Porphyrias Lover and My Last Duchess, through including subjugated female characters, possibly battles to expose the patriarchy that characterised Victorian society. Poes narrator in The Fall of the House of Usher, perhaps similar to Frank in The Wasp Factory, possesses a dual persona, or doppelganger, which accentuates the transgressions of which all humans may be capable of. In this way, through exposing the unnatural, the gothic advocates rationality and, as Kà ¼hne argues, acts as final safeguarding device against the invasion of the monstrous in the readers actual life.

The Smacking of Children should be banned by Law :: Child Abuse Violence

I firmly believe that the smacking of children should be banned by law. For me, there is no real debate in this matter. Many parents abuse the right to smack their children, which can lead to severe consequences. Children grow up copying and learning from their parents from a young age. If parents drink and smoke, their children may want to copy them. If parents smack, their children will think that it is acceptable to be violent and will be more likely to smack their own children in the future. Surely the main consideration in this case is that, if parents choose to smack their children they are damaging them, not always physically but definitely psychologically. I don?t believe that smacking is in any way acceptable, as the smallest bit of violence against children could cause them to use it themselves when they are older. Today, the law states that parents are allowed to hit their children as long as they leave no mark, graze or bruise. There are constantly cases in the media, involving the abuse of the right to smack children in Northern Ireland. This is because parents have been abusing this right more frequently in the past couple of years. I believe the reason for this is that most children have been exposed to violence in their homes, which has led them to be violent in their future. It is a vicious circle. Also, by beating children we are telling them that it is acceptable to smack, which will create more violence in the future, therefore making the matter worse. In dealing with this issue can we ignore the fact that there is no debatable reason why it shouldn?t be made illegal? In everyday life, violence doesn?t need to be used to control children?s behaviour. Most parents say that they use smacking as a way of controlling their children when they are disobedient. For example, if a child kept reaching for an open fire even when they are repeatedly told not to by the parent, the parent would eventually resort to smacking the child. I think the better alternative to this situation would be to buy a fire guard. This way, the child would learn that the fire is out of bounds in a non-violent way. I believe smacking can affect children when they become adults in two ways. They could disagree with smacking their own children because they didn?

Chemistry Acid-Base Titration

Chemistry: Strong Acid and Weak Base Titration Lab Cherno Okafor Mr. Huang SCH4U7 November 21st, 2012 Data Collection and Processing Concentration of the standard HCl solution: 0. 1 M Data Collection: | Trial 1| Trial 2| Trial 3| Final HCl Buret Reading  ± 0. 05 mL | 38. 3| 45| 54. 5| Initial HCl Buret Reading  ± 0. 05 mL | 29. 9| 38. 3| 45| Volume of NaHCO3 used  ± 0. 1 mL | 9. 2| 9. 5| 9. 8| Qualitative Data: I used the methyl orange indicator which was suitable for my titration because of its clear and distinct colour change from orange to a bright red at the endpoint * At the beginning of the titration after I added 3 drops of methyl orange into the base (NaHCO3) and swirled, I began titrating the acid (HCl) slowly, and initially in the methyl orange and base, there was a tiny amount of red colour present, but then it quickly disappeared due to insufficient HCl (H+ ions)then I gradually kept titrating more acid while swirling and there was even more red colour present, unti l finally I reached the endpoint when the orange-yellow colour had completely transformed into a red colour * Changes from an orange-yellow colour (slightly higher pH 4. 4) to a bright red colour (at low pH 3. 1) at the endpoint and point of equivalence * Baking Soda (NaHCO3) absorbed the odour caused by the strong acid of HCl when I mixed the two: bleach-like smell ProcessingIf the concentration of an acid or base is expressed in molarity, then the volume of the solution multiplied by its concentration is equal to the moles of the acid or base. Therefore, the following relationship holds: nVb x Cb = Va x Ca Where: Vb = the volume of the base Cb = the concentration of the base Va = the volume of the acid Ca = the concentration of the acid n = the mole factor In the case of hydrochloric acid and Sodium Bicarbonate (Baking Soda), the mole ratio is one to one, thus the mole factor is 1. Therefore, the volume of sodium bicarbonate multiplied by its concentration in molarity is equal to the moles sodium bicarbonate. The moles of sodium hydroxide are equal to the number of moles of hydrochloric acid in the reaction.The neutralization equation becomes: HCl + NaHCO3 NaCl + H2O + CO3 Hence, Cb = Va x Ca / Vb. Trial 1 Calculation: * First we need to find the change of volume of the acid used up in the titration: Va = Vfinal – Vintial Va = 38. 3  ± 0. 05 – 29. 9  ± 0. 05 Va = 8. 4  ± 0. 1 mL Therefore, nVb x Cb = Va x Ca (1)(9. 2  ± 0. 1)(Cb) = (8. 4  ± 0. 1) (0. 1  ± 0. 0005) Cb = (8. 4  ± 0. 1) (0. 1  ± 0. 0005) / (9. 2  ± 0. 1) Cb = (8. 4  ± 1. 19%) (0. 1  ± 0. 5%) / (9. 2  ± 1. 09%) Cb = (0. 84  ± 1. 69%) / (9. 2  ± 1. 09%) Cb = 0. 0913  ± 2. 78% 0. 0913  ± 0. 00254M is the concentration of the base for trial 1Theoretical Base Concentration = 0. 1  ± 0. 0005 M Experimental Base Concentration = 0. 0913  ± 0. 00254 M Trial 2 Calculation: * First find change of volume of the acid used up in the titration: Va = Vfinal â⠂¬â€œ Vinitial Va = 45  ± 0. 05 – 36  ± 0. 05 Va = 9. 0  ± 0. 1 mL Therefore, nVb x Cb = Va x Ca (1)(9. 5  ± 0. 1)(Cb) = (9. 0  ± 0. 1) (0. 1  ± 0. 0005) Cb = (9. 0  ± 0. 1) (0. 1  ± 0. 0005) / (9. 5  ± 0. 1) Cb = (9. 0  ± 1. 1%) (0. 1  ± 0. 5%) / (9. 5  ± 1. 05%) Cb = (0. 9  ± 1. 6%) / (9. 5  ± 1. 05%) Cb = 0. 0947  ± 2. 65% 0. 0947  ± 0. 00251M is the concentration of the base for trial 2 Theoretical Base Concentration = 0. 1  ± 0. 005 M Experimental Base Concentration = 0. 0947  ± 0. 00251 M Trial 3 Calculation: * First find change of volume of the acid used up in the titration: Va = Vfinal – Vinitial Va = 54. 5  ± 0. 05 – 45  ± 0. 05 Va = 9. 5  ± 0. 1 mL Therefore, nVb x Cb = Va x Ca (1)(9. 8  ± 0. 1)(Cb) = (9. 5  ± 0. 1) (0. 1  ± 0. 0005) Cb = (9. 5  ± 0. 1) (0. 1  ± 0. 0005) / (9. 8  ± 0. 1) Cb = (9. 5  ± 1. 05%) (0. 1  ± 0. 5%) / (9. 8  ± 1. 02%) Cb = (0. 95  ± 1. 55%) / (9. 8  ± 1. 02%) Cb = 0. 0969  ± 2. 57% 0. 0969  ± 0. 00250M is the concentration of the base for trial 3 Theoretical Base Concentration = 0. 1  ± 0. 0005 MExperimental Base Concentration = 0. 0969  ± 0. 00250 M * Now, I will average all 3 trials: Trial 1: 0. 0913  ± 2. 78% 2. 78% / 100% x 0. 0913 = 0. 0913  ± 0. 00254 M Trial 2: 0. 0947  ± 2. 65% 2. 65% / 100% x 0. 0947 = 0. 0947  ± 0. 00251 M Trial 3: 0. 0969  ± 2. 57% 2. 57% / 100% x 0. 0969 = 0. 0969  ± 0. 00250 M Therefore: (0. 0913 + 0. 0947 + 0. 0969)  ± (0. 00254 + 0. 00251 + 0. 00250) / 3 trials = (0. 2829  ± 0. 00755) / 3 = (0. 0943  ± 0. 00252) MAverage Concentration of base for the 3 trials * Percentage Error = Theoretical – Actual / Theoretical x 100% = (0. 1  ± 0. 0005) – (0. 0943  ± 0. 00252) / (0. 1  ± 0. 0005) x 100% = 0. 0057  ± 0. 00302 / 0. 1  ± 0. 0005) x 100% = (0. 57  ± 0. 00352) x 100% = 5. 7%  ± 0. 00352 Conclusion and Evaluation: Conclusion: In this titration lab, I used a s trong acid HCl (hydrochloric acid) vs. a weak base NaHCO3 (sodium bicarbonate/baking soda). My intent was to find the concentration of the weak base after it has been titrated with the strong acid. The theoretical basic solution had a concentration of 0. 1  ± 0. 0005 M. In my experiment, the value I obtained was 0. 0943  ± 0. 00252 M, which is pretty close to 0. 1. I also had a very small error percentage at just 5. 7%  ± 0. 00352 error. My experimental value was only off by 0. 0057 (0. 1- 0. 0943) with a total uncertainty of 0. 00402 (0. 005 + 0. 00352) from the theoretical value of the base concentration. Evaluation/Improvement: Some of the most notable errors in my procedure to mention are the small quantities being used and hence the inaccuracy in measurements. Perhaps I could have arranged the titration to have bigger titres, which would reduce errors by using larger quantities such as a higher concentration for the standardized solution. In addition, there was also some splattering/loss of the acidic solution being titrated into the basic solution, as it came into contact with the edges and surface of the flask, which in turn, presumably initiated errors in volume measurements.Also, this means that not all of the acid that was added reacted efficiently with the basic solution mixed with methyl orange indicator. Moreover, there could have been impurities in the basic solution itself and as well as the indicator causing a higher reading than the theoretical value of concentration. The leakage that resulted from the stock cock may have caused the HCl to alter slightly in content because of the reaction with some of the chemicals in the external environment (air). There was also some residue that could have been left behind in the basic flask when I washed it with distilled water after the neutralization of each trial. Perhaps drying it could have made a difference instead of leaving it wet.Maybe some of the neutralized solution was left behind after I washed out the flask, and it mixed with the tiny water droplets also left behind in the flask. Before I started the next trial, it could have interfered with that titration and provide inaccuracy. Another error to mention is getting the exact endpoint during the titration. The indicator could have ranged from different shades of red (starting with orange) but I assumed that the moment it turned a standard red colour, it was finished. In addition, I could mention that I may not have properly swirled the solutions before beginning the titration process to make sure nothing (residue) settles at the bottom.This could have impacted the inaccurate colour change of the indicator in the neutralization and hence unknown standard colour. I also kept on adding drops when the solution was already a red colour towards the end. However, this may have either darkened or lightened the colour too much in an effort to change the precision of the indicator colour at the equivalence point or end point . Finally, at some moments, I was in a hurry to finish titrating, and so I may have flushed out the acid in large amounts. I realize that near the neutralization point, the acid must be released in drops. However, for the third trial, I did sort of flush out a large amount of the acid and therefore could have missed the neutralization point which could cause errors in results.
