Europe in the International Economic Order Research Paper

Europe in the International Economic Order - Research Paper Example The European Union was formed with the aim of strengthening the economic and political powers of the European countries and emerge as an international superpower. The emergence of the Euro is also a part of this project. Euro was introduced as a common currency for the participating European nations to remove the exchange rate risks within the internal market, to boost up trade across nations and most importantly to bring in monetary stability in Europe. (Fedee, n.d.) Another major purpose was to challenge the increasingly monopolistic power of the currency dollar as a single international currency and to rescue its members from the fluctuations of the dollar. The introduction of Euro has been the most important development in the international economy; it has become the major medium of trade especially in the euro area and other European countries. â€Å" Euro has played a major role in fostering harmony among diverse economies, which had conflicting monetary and fiscal policies, t ariffs and other restrictions on trade and investments† quotes Haruhiko Kuroda, head of Asian Development Bank at this years Brussels Economic forum (Vucheva, 2009). The Eurozone formed covering 11 countries in 1999, â€Å"Belgium, Germany, Spain, Italy, Ireland, Luxembourg, the Netherlands, Austria, Portugal and Finland† (Q&A: Euro basics, 2002). Greece was allowed to join only after 2001, later Slovenia Malta and Cyprus followed the suit, Slovakia became the 16th country to join the group. (Vucheva, 2009) Joining Eurozone it had the advantage of trading its inflation prone home currency to the stable Euro. It also gained an upper hand in the borrowing activities, which led to an increase in liquidity in the market which in turn improved the standard of living of the Greek citizens. Loans for individuals, governments as well as corporate houses were available at very low-interest rates, which are available only among the developed nations like Germany.

Any controversial issue of interest to explore - Essay Example Some of the well known social media platforms include Facebook, Google+, Wikipedia, Linkedln, Twitter, Pinterest among others. The use of social media as a means of propagating information has attracted divergent views and opinions as some argue in its favour while some feel that social media is not a proper tool for sharing thoughts and other information. Those who are against the use of social media have defended their line of thought on a number of factors which include the fact that social networking reduces face-to-face interaction. The autonomy associated with the virtual world allows people to create a lot of fantasy persona or pretending to be someone else. It thus creates a means through which some people can avoid the realities of life leading to increased cases of mistrust. Someone can easily block or cut off the flow of communication from another person whom they may not share similar views and opinions. Online communication is a tool towards crippling the development of social skills and conflict resolution strategies. Negative opinions toward social media have been supported by the fact that it is a means of fraud or identity theft. The information sent on social media platform can be accessed by anyone who has interest in it even those to whom it was not intended to reach. The information is subject to different interpretations and misunderstanding (Wankel, 34). The aspect of sharing personal information puts people at risk of being defrauded as some criminals have mastered the act of stealing personal details. Hacking presents a major weakness of social media as evident by the increasing cases of accounts and profiles of people being hacked. This leads to serious misdemeanor of identity theft and the process does not need on to be very techno-savvy to be successful but just a little knowledge in technology. Sensitive information such as passwords,

Major determinant of Cross-elasticity of Demand

Major determinant of Cross-elasticity of Demand When it comes to Cross-elasticity of demand, we must first illustrate the concept of elasticity of demand. We can say that elasticity of demand is the foundation of the theory of cross-elasticity of demand because elasticity of demand is related to only one good while cross-elasticity of demand is about the relation of 2 goods. We should first compare the elasticity of demand with the cross-elasticity of demand. Introduction of Elasticity of Demand Elasticity of demand is often referred to as the own-price elasticity of demand for a certain good, such as the elasticity of demand with respect to the price of a good. Elastic demand reflects that consumers are very price sensitive. This concept is understandable because we all know price is one of important determinant of quantity, and the quantity demanded of a good is negatively related to its price. We can suppose: for a seller, lower price promotes sales; for a buyer, higher price constraints their desire of purchase. Take the example from the textbook, suppose that a 10% increase in the price of an ice-cream cone causes the amount of ice cream you buy to fall by 20%. According to the formula We calculate your elasticity of demand as 20%/10%= 2. This result can be explained as the elasticity 2 reflects the change in the quantity demanded is twice as large as the change in the price in proportion. This result owes to reasons as follows: First, market for ice cream is very competitive instead of monopolistic. Second, consumers have choices of other substitutes such as other desserts. Third, when the price of ice cream rises, consumers can buy cakes, milk-shake or other desserts. The above formula usually yields a negative value, because of the inverse nature of the relationship between price and quantity demanded. They are described by the law of demand (Gillespie, Andrew (2007). p.43.) but economists tend to refer to price elasticity of demand as a positive value (i.e., in absolute value terms). Definition of Cross-elasticity of Demand Based on the theory mentioned above about price elasticity of demand, we can go further to find out the relation of two goods. In order to distinguish it from the elasticity of demand for that good with respect to the change in the price of some other good, i.e., a complementary or substitute good. (Png, Ivan (1999). p.57.) The latter type of elasticity measure is called a cross-price elasticity of demand. In microeconomics, cross-elasticity of demand is also called cross-price elasticity of demand, which measures the responsiveness of the demand for a good when there is a change in the price of another good. According to its definition, it is measured as the change in demand in percentage for the good A that occurs in response to a change in price in percentage of the good B. The formula to calculate cross-elasticity of demand is as follows: Major Determinant The cross-price elasticity of demand is often used to see how sensitive the demand for a good is to a price change of another good. The major determinant of cross-elasticity of demand is the closeness of the substitute or complement. A high positive cross-price elasticity indicates that if the price of a certain good goes up, the demand for the other good goes up as well. A negative one tells us the opposite that an increase in the price of one good causes a decrease in the demand for the other good. A small value (either negative or positive) tells us that there is little or no relation between the two goods. They are listed in the table below: Cross-price Elasticity Indication Example Graph A positive cross-price elasticity If the price of one good goes up, the demand for the other good goes up as well. Pork and chicken, etc. A negative cross-price elasticity An increase in the price of one good causes a drop in the demand for the other good. Bicycles and helmets; Petroleum and cars, etc. A small value There is little relation between the two goods. Things have little or no relation at all For example, if we suppose the price of chicken goes up by 20%, and as a result the quantity demanded of pork increases by 10%, at the premise that there is no change in the price of pork or anything else that would have influence on the demand for pork (such as quality, advertising, location, etc). Then the cross-elasticity of demand for pork, with respect to the price of chicken, is 10%/20% = 0.5. This concept is also easy to understand. Firstly, as we know that for two goods that complement each other show a negative cross elasticity of demand, which means that an increase in the price of one good cuts the demand for the other. For instance, if the price of bicycles goes up, we will expect to see a decline in the demand for bike helmets; if the price of petroleum goes down, the demand for car will be expected to rise. In this sort of case, we can say the goods are complements and they have a close link in price and demand. Secondly, on the contrary, two goods that are substitutes have a positive cross elasticity, it means that an increase in the price of one good will therefore increase the demand for the other good. When we observe a positive cross-elasticity, we can assume that the two goods are substitutes, as with chicken and pork, butter and margarine. The Third circumstance is two independent goods. If two goods are independent, undoubtedly they have a zero cross elasticity of demand. Practical Application For firms and corporations, it is necessary for them to know the cross-elasticity of demand for their products when they consider the effect on the demand for their products of a change facing with the challenging price of a rivals product or a complementary product. If the quality and appearance is almost the same (regardless of the factors of affection location, and loyalty, etc.) but the price of Firm A is higher than that of Firm B, most consumers will choose the products of Firms B. Among theories of marketing, pricing is not only difficult but technical. These are vital pieces of information for firms when making their production and strategic plans. However, for goods those complement each other, a firm is supposed to promote the sales of both the products and their complements. Nowadays, the price of petroleum is constantly high and it will continuously get higher in the near future. This is definitely a disaster for automotive industry. Some of the automobile companies adopt the strategy of reduction but gets an unsatisfactory feedback. What affects the decision of a consumer is mainly the price of petroleum instead of the automobile, so some companies think out of a promotional tactic: buy car get petro discounted (though the price of a car may be very expensive), and this may be to some extent cater to the consumers psychology. Another application of the concept of cross-elasticity of demand is in the field of international trade as well as the balance of payments around the world. Whats more, for different industries and fields, the concept of cross-elasticity of demand can be used to measure the closeness of relation of each other. For those monopoly enterprises, they are the unique suppliers in market and they are powerful enough to control the whole market, so they wont suffer the pressure from others. However, for some industries, such as Ministry of Railway, if it decides to raise the price in a large scale, many passengers will prefer other transportation, which will make aviation industry or highroad industry prosperous. This will undoubtedly lay itself in an unadvantageous position.

Visions of America Essay example -- Landscaping Painting Art Papers

Visions of America The importance of American landscape painting in the nineteenth century extended far beyond the borders of the art world. The nineteenth century in America was a paradoxical time in which great nationalism and â€Å"enormous self-confidence and optimism† merged with growing disunity (Wilmerding 54), and the glow of â€Å"progress† was inextricably tied to the destruction of the majestic landscape that was a source of American identity and pride. Landscape painters at this time were faced with the difficult task of reconciling these conflicting aspects of American culture and identity. Their paintings blend physical descriptions of the American land with cultural descriptions of the American national identity. American landscape painting was founded primarily by European artists like Thomas Birch, Francis Guy, William Groombridge and Joshua Shaw, who came to America to escape the â€Å"background of political turbulence† in Europe that was the result of the Napoleonic Wars (Wilmerding 40). The most famous and influential of this first group of painters was Thomas Cole. Although Cole’s influences included European artists like Turner, Poussin, Claude, and Salvator Rosa, he came to create a style of landscape painting that, despite its indebtedness to artists like these, was distinctly America in flavor. It was he who â€Å"particularly came to articulate a national consciousness through his paintings, which we now recognize as the beginning of America’s first major landscape style† (Wilmerding 40). With Cole, landscape painting took on a stature in America like that which history painting traditionally possessed in Europe. He was able to â€Å"transfer the heroic aims of history painters to the landscape category, where at ... ...g of the Nineteenth Century: Realism, Idealism and the American Experience.

FAN UP Market Analysis and Sales Projections Essay

FAN UP is positioned within the Smartphone Applications Industry. Mobile devices with remote internet capability, smart phones, have created an entirely new market of users that can be reached on the go. Due to the recent nature of Smartphone technology, we are witnessing rapid growth and innovation in the smart phone applications industry. FAN UP allows the event host the ability to seamlessly pair a sponsor with individuals coming to the event. By doing so, FAN UP will open the door to endless brand reach through Social Media via the user, additional in- ­Ã¢â‚¬ game/concert advertisement, fan appreciation, and a creative way for each event host to use their event to leverage underutilized sponsorships and promote their brand. Industry Analysis Mobile applications have changed a number of industry landscapes in recent history. This industry shows annual growth projections from 2009- ­Ã¢â‚¬ 2014 to be 49.8% and from 2013- ­Ã¢â‚¬ 2018 to be 28.9%. The evidence of this growth is a reason this app will be successful. Competition in the Smartphone Applications Industry is very strong. Because of this, it is important to analyze the different forces at work within the industry. This chart, information gathered from IBIS World, lays out the industry structure: Life Cycle Stage Growth Revenue Volatility Very high Capital Intensity Low Industry Assistance Low Concentration Level Low Regulation Level Medium Technology Change High Barriers to Entry Low Industry Globalization Low Competition Level High The first key external factor in this industry is the number of mobile internet connections. As the number of smart phone purchases increases with the number of mobile internet connections in 2014, app developers will have a larger market for their products. Secondly, as demand from e- ­Ã¢â‚¬ commerce increases in 2014, retailers have expanded their product lines, the platforms on which they operate, and retailers are expected to create more shopping apps to assist time- ­Ã¢â‚¬ strapped consumers. Next, time spent on leisure and sports represents one of the most key external factors. Time spent on leisure and sports is expected to decrease slowly in 2014, resulting in a potential threat for the industry. While the industry now serves a broad audience, leisure time is a major restrictive factor in a consumers’ ability to use and purchase smart phone app products. The US Census Bureau data re- ­Ã¢â‚¬ iterates more of the same industry trends. â€Å"In 2011, U.S. nonfarm businesses with employees spent a total of $289.9 billion on non- ­Ã¢â‚¬ capitalized and capitalized information and communication technology (ICT) equipment, including computer software. This represents an increase of 10.6% from 2010. Of the $65.2 billi on spent on noncapitalized computer software, $29.9 billion was for purchases and payroll for developing software, an increase of 7.3% from 2010. $35.3 billion was for software licensing and service/maintenance agreements, an increase of $3.9 billion (12.6 percent) from 2010.† Although the growth of mobile apps is on the rise, revenue earned from these apps is expected to increase at a slower rate. Over the next five years, consumers are expected to continue wander away from pay- ­Ã¢â‚¬ to- ­Ã¢â‚¬ download apps, forcing developers to embrace the â€Å"freemium† business model that relies on monetizing free downloads after the fact via in- ­Ã¢â‚¬ app purchases. By 2019, free downloads are expected to account for about 95.5% of total mobile app store downloads. In the five years to 2019, revenue is expected to experience a 28.9% increase, reaching a total of a $34.7 billion smart phone application industry. Market Analysis The market analysis for FAN UP is atypical of most apps. FAN UP will start by focusing on the target market of Sports Franchises in the US and Concert and Event Promotion in the US. FAN UP will serve Gym, Health and Fitness Clubs in the US, Ski and Snowboard Resorts in the US, and Amusement Parks in the US in the secondary market. The sports franchise market in the US is comprised of sports teams or clubs that participate in live professional or semiprofessional sporting events (e.g. baseball, basketball, football, hockey, soccer and other team sports) before a paying audience. This market makes up the first half of the target market. Over the five years to 2013, revenue is expected to grow at an average annual rate of 1.4% to $23.6 billion, and includes a 1.5% increase in 2013 alone. The key external factors for the sports franchise market loosely hold true for the entire scope of the FAN UP market. The external factors include per capita disposable income is expected to increase by 0.8% during 2013, the number of households earning more than $100,000 is expected to increase slowly over 2013, external competition from other sports franchises is expected to increase during 2013 which represents a threat in the industry but not the market, and time spent on leisure and sports is expected to decrease slowly during 2013. Industry revenue is expected to expand 1.5% in 2013. Also, some franchises are opening new or remodeling existing stadiums to attract more consumers. Concert and Event Promotion in the US is the second half of the target market. This market creates, manages and promotes live performances and events, ranging from concerts and theater performances to state fairs and air shows. This industry has an annual growth projection of 2.6% from 2013- ­Ã¢â‚¬ 2018 with 49,825 operating businesses. Federal funding for Creative Arts is the key external factor that deviates from the sports franchises market. Many nonprofit establishments in this industry rely to some extent on federal funding, particularly grants from the National Endowment for the Arts, an independent agency that Congress established in 1965 to support the arts. Federal funding for creative arts is expected to increase slowly during 2013. This market has a history of good performance even when other industries struggle. Except for moderate wavering in 2010, the economic downturn ha s done little to deter Americans from attending live concerts and other entertainment events. Over the five years to 2013, industry revenue has grown at an estimated annualized rate of 1.3% to $23.7 billion, including a 3.5% anticipated increase in 2013. Revenue Model FAN UP will create revenue through brokerage fees, reach bonuses, and advertising. This recurring revenues model will be paid by the host of the event (i.e. Carolina Panthers, Live Nation, etc.) for each event in which FAN UP participates. The app will be free from the App Store because, as shown in the data, consumers are increasingly less likely to pay for an app. The brokerage fees are for the access to the app’s consumer base. The reach bonus is in place because with more reach, the more the host can charge the sponsor of the FAN UP sponsorship package. The FAN UP pricing will be dynamic in that negotiations must take place with each new partner in order to agree upon the percentage of the FAN UP sponsorship that FAN UP will receive. The price of the FAN UP sponsorship package will be a negotiation be tween the event host and the brand. Works Cited: 1. IBIS World 2.

Executive Summary Social Networking Essay

Introduction We are at a time when customer satisfaction is at an all time low, yet it is becoming a more and more difficult to talk to a human for customer service. Many businesses have lost the personal and trust-filled relationship that is so desired by their clients. In order to maintain and grow a loyal customer base, a company can now achieve those real human connections by means of social networking. Individuals from all areas of the company are readily available to meet the diverse needs of its customers, future employees and each other. Social Networking is at the top of today’s technology and is being utilized by many companies. Our business purpose is to share business ideas and opportunities. This has become an effective tool to meet prospective leads, clients, efficient employees and business partners. [i] Social networking is an easy and cost effective way to make profitable business connections with people that you never knew existed. Recommendation ââ€" ª An advantage of Social Networking is to create new ways to communicate and share information about our company. Communication is a key to success in any business, and social networking is the best way to facilitate these successful interactions. ââ€" ª Social Networking ensures that our company is making new and successful connections. We are able to promote our company’s services on a more personal level.[ii] Both our customers and own employees can build a more trusting relationship through the ease of communication of a social network. Analysis Social Networking has always been an effective source of communication. It has become necessary to change they way we pursue our clients and employees. We want to manage more efficiently, hire the most qualified employees and locate potential clients. Our business has to be aware of not only what we communicate, but how we communicate. Society has changed they way we interact with one another. It use to be highly encouraged, by employers, to meet a potential client or future employee while playing golf, having lunch or maybe even dinner. You would provide your sales pitch, hand them a business card and follow back within the next few days to see if they were interested in your business or if you were interested in theirs. This was an approach to maintain a personal relationship and show your future client or future employee how available and interested you are. Social Networking has grown and we need to be aware of the way we connect and communicate. Communication is no longer just reaching a client or future employee. It is reaching millions of business connections that you never knew existed, through technology. Technology has allowed us to create social sites that can be used for networking your business, via the internet. I use to think social sites such as Myspace.com, Facebook.com, and LinkedIn.com were sites for younger people to socialize with their friends. After researching these sites, I found that these sites support much more than socializing amongst friends. It has become one of the most effective ways for businesses to communicate and build relationships with other business people and potential employees. Social networking has provided businesses with the following: business development or sales, raising business capital, professional development, getting job assistance with others in your company, recruiting board members, management of employees and social or personal reasons.[iii] Social Networking can add value to a company externally as well as internally. It can be a very powerful tool and when utilized properly we can learn from others as well as ourselves. There are many companies that have taken the idea of these social sites and utilized them internally. They are using social networking as marketing tool for growing their business. Social Networking is now essential professional competency for employees at all levels. Professionals need to know how to gain visibility and credibility in their target markets and how to build and maintain relationships for long-term growth. They need to develop strategic networking skills and practices to excel. It is the most important tool for intelligence gathering. In a business setting, such as conferences, meetings, and outings, people need to find the latest information on resources, trends and best practices. It is a critical strategy for business development. Employees can create a network of profiles and connect with one another. Enabling connections among employees, the company could easily establish virtual teams, bring new employees up to speed, improve collaboration and increase retention among people who hadn’t felt a strong sense of belonging.[iv] Social Networking is a method for personal retention because it creates feelings of inclusion and helps people from diverse backgrounds feel listened to and valued. Building up a network of diverse people is very helpful for any business. Contacts with different clusters or groups would help your possibility of greater opportunities. A closed group of contacts will not allow you this kind of exposure. Networking can help you with your contact list. This would then help you to expand your sales and social base. [v] It remains the primary technique that people use to find jobs, change careers or land on their feet after a layoff, merger, or reorganization.[vi] Through the company’s social network you can create a word-of-mouth marketing stream that reaches people you would never be able to reach on your own or other means. Experts can provide feedback or validation regarding your current ideas or help to create new ones. You can create an advisory board of business people that are regularly available to you and committed to the growth and success of your business. People are given the opportunity to brainstorm which allows you to get outside of the normal way of thinking and create new and innovative ways to grow your business. People in your social network can connect you with potential employees.[vii] Companies are communicating and connecting using external sites as a tool to check up on employees who are working for them or are a potential candidate. We want to make sure we are ahead of the game, the who’s who if you will. Potential employees seem to be younger and younger. They are not all exploiting the typical Monster.com and CareerBuilder.com to post their resumes or look for jobs anymore. They are developing personal sites with LinkedIn.com and Facebook.com, which are allowing a more personal view of a potential employee or client. More than one in five employers searches social networking sites to screen candidates. There are many areas of concern that can be researched on networking sites including: information about drug and alcohol use, inappropriate photos, poor communication skills, bad-mouthing of former employers or fellow employees, inaccurate qualifications, unprofessional screen names, notes showing links to criminal behavior, and confidential information about past employers. This is a very effective way to help determine whether a candidate should be hired. You want an employee that can show a professional image, solid references and are a well-rounded candidate in terms of their skills, accomplishments and overall fit for the company.[viii] Closing Social Networking is a smart and strategic way to keep our company connected and communicating both internally and externally. Remember the old saying, â€Å"It is not always what you know, but who you know† and social networking has been an effective tool that has allowed us to broaden our personal relationships with our customers, future employees and each other. Social Networking through technology will allow us to grow with endless possibilities. ———————– [i] Raj, N. A. (2008). For Entrepreneurs: Social Marketing Optimization.

We Should Stop Wars Essays

We Should Stop Wars Essays We Should Stop Wars Essay We Should Stop Wars Essay We Should Stop Wars Jonathan Granoff – â€Å"Nuclear Weapons, Ethics, Morals and Law† Ron Paul – â€Å"Conscription: The Terrible Price of War† Jonathan Granoff – â€Å"Peaace and Security† War and Terrorism is perhaps one of the hottest topics in the U. S. The debate on whether a mosque should be built two blocks away from ground zero has refreshed people’s memory of the terrorist attack nine years ago. Many people in the U. S. believe that we are in a just war with the terrorists who threat the peace of the world. However, how many classifications can wars be categorized? What kind of war should be permissible? In my opinion, the existence of war is evil and should be limited to the minimum possible level. First, I want to argue about the justice of a â€Å"just war†. A just war means it fits both jus ad bellum (the right to go to war) and jus in bello (the just conduct of war) (Boss, 575). Let me start analyzing from the jus ad bellum. As we know, war involves the use of armed violence between nations or between competing political factions to achieve a political purpose (Boss, 571). A war usually starts when two parties believe different thing. Namely, under many circumstances, both sides in a war believe themselves are just and the other side is evil. Even some countries try to start a war that is â€Å"unjust†, they will create a â€Å"just cause†. The Iraq War is an example. I remember in the movie â€Å"Jarhead† about 1990 Gulf War, there is a scene that the military leaders were showing the troops how just this war is by protecting Kuwait from Iraq’s invade, then a soldier whispered to another saying that this war is just for the oil. After failing to prove that Saddam Hussein possessed weapon, the Iraq War is widely considered as an unjust war based on economic purpose. However, how many times can we prove the just cause of a war? How can we prevent any organization from starting another â€Å"Iraq War† if we allow them to use just war as an excuse? The second ingredient of a just war, jus in bello, is also questionable. One frequently used example of just war is when U. S entering World War II. However, the nuclear bombs dropped on Japan definitely violated the principle of jus in bello that â€Å"noncombatants should not be intentionally targeted (Boss, 576). † Nuclear weapon is viewed as â€Å"the ultimate evil† because it could permanently destroy the ecosystem in a large area. â€Å"Not only are they destructive in magnitude but in horror as well (Granoff, 601). Thus, many people are working at stop using any nuclear weapon. Those efforts currently met two problems. The first problem is the potential threat from the countries that already developed nuclear weapons. As long as a group of people have nuclear weapons, the attempt of some others to develop nuclear weapons will still go o n. The second problem is what kind of weapon is considered â€Å"not a proportional response to the injury being redressed†? Should we allow the predator drone to vaporize people or the biological weapon that could spread diseases? Where is the limitation of the â€Å"humanity† for a war? Is killing one person to protect ten other persons a just behavior? What about killing one person to protect a thousand persons? Loss of lives in wars could hardly be just for any reason. In addition, whether a war in the history is a just war is decided by the winner most of the time. The U. S. Independence War is widely viewed as a Just War. The author Boss said that the behavior of France helping the U. S. is just. I cannot agree with him. At that time, the independence of the 13 colonies was viewed as a violation of fidelity. The assistant from France is just based on its economic consideration. What if a Native American reservation claims for independence now? The winner of a War is usually the â€Å"just† side. And when a group lacks the power to engage in conventional warfare, this group might use politically motivated violence to target noncombatants and create intimidation, which is terrorism (Boss, 572). At this point of view, if an organization to not want to be terrorism, this organization needs to have the military power to directly confront enemy. We always condemn terrorist because of the method they use. What about ourselves? According to the Stockholm International Peace Research Institute Yearbook 2010, the U. S. military spend of the U. S. consists 46. 5% of the whole world’s military spend. Does the U. S. need to maintain the largest military spend in order to secure the â€Å"strongest country† in the world? This is questionable. War has never stopped after World War II. There are still about 1. 6 million people killed every year now (Boss, 572). If we allow one type of war to exist, we will give war makers excuse to create other types of wars. As long as human nature does not change, people will seek for more resources and conflict will exist. We must make every effort to stop war.

Red River Rebellion Essays

Red River Rebellion Essays Red River Rebellion Paper Red River Rebellion Paper Essay Topic: Second Treatise of Government This paper will look at the views of five different authors and their views on the Red River Rebellion. The sources that surround the Red River Rebellion come from people of many different scholarly backgrounds, walks of life and opinions. To really understand an event that happened so long ago it is important to see the way that a variety of different people have viewed the issue. Some differing approaches to this occurrence in 1 869 showing many sides and views of what happened such as the Idea that Riel could not have been behind the rebellion, the Idea that It was In fact Riel who made the Red River Rebellion happen, the involvement of the British in the conflict, blame that may be placed on the Canadian government at the time and the perspective of the MÂ ©its peoples are all very important aspects that must be looked at as one searches for Ideas about the Red River Rebellion. The five sources that have chosen to look at which show in very different lights where the blame should be placed for the Red River Rebellion of 1869 are as follows. Thomas Flagmans Political Theory of the Red River Resistance, written in 1978, G. Ens Prologue to the Red River Resistance: Prenatal Politics and the Triumph of Riel, written in 1994, J. P. Smiths Riel Rebellion of 1869: New Light on British Liberals and the use of Force on the Canadian Frontier, from 1995, J. M. Bunkmates Crisis at Red River: 125 Years Ago Louis Riel Defied Canada also written in 1 995, and finally Donald Paunchs 1988 book The MÂ ©its. In 1978 Thomas Flanagan wrote an article In the Canadian Journal of Political Science, entitled Political Theory of the Red River Resistance: The Declaration of December 8, 1869. This article makes the major point that critical texts such as this declaration must be examined critically from the perspectives of many types of scholars Including the political scholar. The key conclusion that Flanagan draws from the political analysis of The Declaration of December 8, 1869- which is also known as the Declaration of the People of Ruptures Land and the North West is that the billion was not actually Louis Riels work as so many believe it is. Flanagan speaks of Riel and the people of Red River as being Immature and unreasonable; he says that they would have been unable to rebel in such a large way without some intense help and advice. The main source that Flanagan uses is the actual Declaration of December 8, 1869, as this Is what much of his article Is based around. However It is not the only source that he has used to help him draw the conclusions about Riel and the Red River Rebellion which he has discussed. Flanagan also sites A. G. Memories A Critical Theory of the Red River Insurrection, G. F. G Stanley The Birth of Western Canada and John Lockers Second Treatise of Government throughout his article. These sources all seem to do a good Job In backing up the point that Flanagan makes regarding Riels Inability to have been the mastermind behind the Red River Rebellion, however John Lockers 1 OFF second I rattle AT Government, although a g source Tort many Ideas Ana writings, seems not to fit in regarding this specific topic, as it may have more to do with political actions in Europe rather than in the early days of Canada. Flagmans article is written very clearly from a political perspective and from this moms a clear bias. This political theory paper discusses in detail the incapability of Riel and through this argument one may see that Flanagan gives very little credit to the MÂ ©its for the planning of the rebellion which they as a community carried out. This bias is obvious and the language used shows almost a disdain for the MÂ ©its population and portrays them in a very diminutive and incapable light, giving them no credit at all for the thought behind the actions which were taken in 1869. While Flanagan argues that Riel was not the mastermind behind the Red River Rebellion Gerhard J. Ens looks at this event in a very different light in his article Prologue to the Red River Resistance: Pre-lamina Politics and the Triumph of Riel. This article by Ens discusses the early period of the Red River Rebellion/Resistance prior to the occurrence of the barrier being erected at Riviera Sale by Riel and his men preventing the newly appointed Lieutenant Governor from entering the Red River colony. The plight of Riel and the work that he put into this rebellion is discussed by Ens as he speaks of the competition to assume leadership of the MÂ ©its cause in the Red River colony. Riel won the leadership rights Ens tells us as he stressed the rights of French and Catholic people rather than the minimal rights of the Aboriginal community. Ens argues in his article that this leadership competition set the tone for the larger rebellion that was to come. In this sense Ens article and Flagmans article differ, however Ens also says to the reader that Riels attempt to build consensus within the colony was impeded. Ens uses a variety of sources to construct his argument on the Red River Rebellion. The main sources that he cites are The Collected Writings of Lois Riel, Seasonal Papers from Canadas Parliament (House of Commons), Red River Journal by Alexander Begs and interestingly enough, Political Writings on the Red River Rebellion by Thomas Flanagan. The sources that Ens uses to substantiate his argument seem much more effective as many of them are primary sources and give perspectives from the MÂ ©its who were actually a part of the community in which the rebellion occurred. Ens uses the writings of people such as Louis Riel to give a clear picture of what was actually going on and how the MÂ ©its viewed the issue as well as vying the perspective of the Canadian government and looking at documents that came from them to see their point of view and actions in regards to the Red River Rebellion. A very different picture of the Red River Rebellion of 1869 is given by James Patterson Smith in his article entitled Riel Rebellion of 1869: New Light on British Liberals and the use of Force on the Canadian Frontier. Patterson Smith looks at the Red River Rebellion in terms of imperial considerations. His article discusses the British involvement on the Canadian frontier making many valid points regarding this involvement. Patterson Smith focuses mainly on the point that Britains official policy was to withdraw British garrisons from Canada and other self governing colonies at the time, however Canadas commitment to the empire and belief in the value of the empire to Britain in terms of world politics drove Canada to prod Britain into Involvement In Trotter Issues sun as ten Rear Ruler Relation. Nils article, Wendell different from the others in the perspective that it takes seems to be very important in understanding the motives and the forces behind the decision of the British to ploy imperial troops in Manitoba to end the rebellions. While the other articles focus on whom and what was the main force and brains behind the rebellions, Patterson Smith shows the other side, the British side. Patterson Smith like Ens, references the Political Writings on the Red River Rebellion by Thomas Flanagan, he also uses a variety of documents from the Colonial Office Minutes on Young Correspondence and the Colonial Office Confidential Memorandum Regarding Disturbances in the Red River Settlement. All of these sources seem to be extremely beneficial in the writing of this article regarding British involvement as Patterson Smith has gone straight to the source of where and why the British became involved in the conflict by looking at the meetings that were held and the documents which were created. A bias is definitely shown in James Patterson Smiths article, as it is all about the British perspective and discusses how it was the Canadian governments idea to involve the British. This article does not really show the perspective of the MÂ ©its populations involved in the rebellion which may have been useful in showing other reasons for why the Canadian government may have needed the assistance of the British on the Canadian frontier. Bias is inevitable in article such as this however and in this article it seems as if the bias is necessary and very useful in giving the reader a look at the Red River Rebellion from a different viewpoint. So far the Red River Rebellion has been looked at as being thought up and the fault of someone much more intelligent and mature than Louis Riel, as well as by Riel. We have also looked at the perspectives of the British government regarding their involvement in the Red River Rebellion. It is only fitting in this view of whos fault ND the way on which different people were involved and effected to look also at the rebellion as being the fault of the Canadian government. J. M. Bumpiest, a professor of history at SST. Johns College, University of Manitoba writes an article entitled Crisis at Red River: 125 years ago Louis Riel Defied Canada. This article discusses a variety of ideas regarding the Red River Rebellion and how and why it occurred. Bemused argues that the Red River Rebellion was almost inevitable as the MÂ ©its populations, as any other population would do, resisted the takeover of land by Canada surrounding the Red River Community. It was in fact the fault of the Canadian government that the Red River Rebellion began as they were sloppy and unwilling to let the community know what was going on says Bemused. Although the exact sources that Bemused uses to substantiate his claims are not given it can be seen that he uses many sources such as minutes and acts passed by the House of Commons in Canada as well as proclamations made by various people such as Louis Riel and important Acts that were essential during the period of rebellion such as the Manitoba Act. These sources give the paper an overall feeling of Ruth and reliability as Bemused frequently quotes documents and people who were present at the time of the 1869 Red River Rebellion. This article seems very different than the others in the way in which it is written, it is fairly obvious that it is the work of a historian and is a very good contrast to other articles by political theorists, anthropologists, Ana a wee variety AT toner canolas. It Is very Interesting to see ten thoughts of Bemused as a historian and his thoughts seem to encompass those of many other historians. A bias is very clearly presented in Bunkmates article as he blatantly discusses the stakes and stupidity of the Canadian government in not informing the Native populations surrounding Red River about what was happening. Bemused very obviously feels that the rebellions were not the fault of the MÂ ©its populations although they were the ones to begin the violence, but that they were in fact initiated by the natural reaction that the MÂ ©its would have had to what the Canadians were doing about the land surrounding them. The final work that will be looked at in regards to the Red River Rebellion is a book by D. Purist, The MÂ ©its. Throughout this work the lives and customs as well as the story of the MÂ ©its is discussed in great detail. One chapter in particular however deals extensively with the Red River Rebellion. This work does not display an argument regarding the rebellion or an opinion; rather it seems to be an attempt at giving the facts of the events of 1869 from the perspectives of many, not only the government but also the MÂ ©its peoples. Purist uses many different sources in the writing of his book, everything from books and government documents to court decisions and the press. This book is very well written and the extensive list of sources that Purist has drawn upon gives the kook credibility as he looks at various sources from Native peoples or MÂ ©its perspectives as well as those by the Canadian government and other individuals of European descent. This book while giving a seemingly unbiased and factual account of the Red River Rebellion does have an underlying bias as it is written to share the story of the MÂ ©its. For this reason the Canadian government and other people who opposed the MÂ ©its during the time of the Red River Rebellion are looked at in a very different light.

Father Coughlin, the Depressions Radio Priest

Father Coughlin, the Depression's Radio Priest Father Coughlin was a Catholic priest based in the parish of Royal Oak, Michigan, who became a highly controversial political commentator through his extraordinarily popular radio broadcasts in the 1930s. Originally a devoted supporter of Franklin D. Roosevelt and the New Deal, his radio sermons took a dark turn when he became a bitter critic of Roosevelt and unleashed fierce attacks tinged with anti-Semitism and flirtations with fascism. In the misery of the Great Depression, Coughlin attracted a vast audience of disaffected Americans. He teamed up with Louisiana’s Huey Long to build an organization dedicated to social justice, and Coughlin actively sought to ensure that Roosevelt would not be elected to a second term. His messages eventually became so controversial that he was ordered by the Catholic hierarchy to cease his broadcasting. Silenced, he lived out the last four decades of his life as a parish priest largely forgotten by the public. Fast Facts: Father Coughlin Full Name: Charles Edward CoughlinAlso Known As: The Radio PriestKnown For: Catholic priest whose radio sermons made him one of the most influential people in America before endless controversy led to his downfall and silencing.Born: October 25, 1891 in Hamilton, Ontario, CanadaDied: October 27, 1979 in Bloomfield Hills, MichiganParents: Thomas Coughlin and Amelia MahoneyEducation: St. Michael’s College, University of TorontoFamous Quote: Roosevelt or Ruin! Early Life and Career Charles Coughlin was born in Hamilton, Ontario, Canada, on October 25, 1891. His family had mostly lived in the United States, but had crossed the border before his birth when his father found work in Canada. Coughlin grew up as the only surviving child in his family and became a very good student, attending Catholic schools in Hamilton followed by St. Michael’s College at the University of Toronto. He graduated in 1911 with a Ph.D., having studied philosophy and English. After a year touring Europe, he returned to Canada and decided to enter the seminary and become a priest. Coughlin was ordained in 1916, at the age of 25. He taught at a Catholic school in Windsor until 1923, when he moved across the river to the United States and became a parish priest in a Detroit suburb. (Original Caption) Detroit: Owners And Founder Of Social Justice. Father Charles E. Coughlin, left, says ownership of the weekly Social Justice has for two years been in hands of his mother and father, Mrs. Amelia Couhglin and Thomas J. Coughlin, right. Despite Coughlins protests, Social Justice was denied second class mail privilege. A gifted public speaker, Coughlin boosted church attendance when he would deliver sermons. In 1926, the popular priest was assigned to a new parish, The Shrine of the Little Flower. The new parish was struggling. In an effort to increase attendance at mass, Coughlin asked a fellow Catholic who ran a local radio station if he could broadcast a weekly sermon. Coughlin’s new radio program, called The Golden Hour of the Little Flower, began airing in October 1926. His broadcasts immediately became popular in the Detroit area, and within three years, Coughlin’s sermons were also being broadcast on stations in Chicago and Cincinnati. In 1930 the Columbia Broadcasting System (CBS) began putting Coughlin’s program on the air every Sunday night. He soon had an enthusiastic audience of 30 million listeners. Turn to Controversy In his early broadcasting career, Coughlin’s sermons were not controversial. His appeal was that he seemed to be a stereotypical Irish-American priest, delivering an uplifting message with a dramatic voice perfectly suited for the radio. As the Great Depression intensified and auto workers in Coughlin’s home area began to lose their jobs, his message changed. He began to denounce the administration of Herbert Hoover, which eventually caused CBS to stop carrying his program. Undaunted, Coughlin found other stations to carry his sermons. And when Franklin Roosevelt’s campaign gained momentum in 1932, Coughlin joined as an ardent supporter. Roosevelt or Ruin In his weekly sermons Coughlin promoted Roosevelt, and to encourage voters he coined the slogan Roosevelt or Ruin. In 1932, Coughlin’s program was a sensation, and he was said to be receiving many thousands of letters a week. Donations to his parish poured in, and he built a lavish new church from which he could broadcast to the nation. Father Charles Coughlin delivers a radio speech, 1930s. Fotosearch / Getty Images After Roosevelt won the election of 1932, Coughlin vigorously supported the New Deal, telling his listeners the New Deal was Christ’s deal. The radio priest, who had met Roosevelt during the 1932 campaign, began to consider himself a policy adviser to the new administration. Roosevelt, however, had become very wary of Coughlin, as the priest’s economic ideas were venturing far outside the mainstream. In 1934, feeling spurned by Roosevelt, Coughlin began to denounce him on the radio. He also found an unlikely ally, Senator Huey Long of Louisiana, who had also gained a large following through radio appearances. Coughlin formed an organization, the National Union for Social Justice, which was dedicated to fighting communism and advocated for government control of banks and corporations. As Coughlin devoted himself to defeating Roosevelt in the election of 1936, he transformed his National Union into a political party. The plan had been to nominate Huey Long to run against Roosevelt, but the assassination of Long in September 1935 scuttled that. A virtually unknown candidate, a congressman from North Dakota, ran in Long’s place. The Union Party had virtually no impact on the election, and Roosevelt won a second term. After 1936, Coughlin’s power and popularity declined. His ideas became more eccentric, and his sermons had evolved into rants. He was even quoted as saying he preferred fascism. In the late 1930s, followers of the German-American Bund cheered his name at their rallies. Coughlins tirades against international bankers played upon familiar anti-Semitic taunts, and he openly attacked Jews in his broadcasts. Over 26,000 people tuned in to hear the speech given by Reverend Charles E. Coughlin in Cleveland. He spoke of President Roosevelt as the Financial Dictator of the United States and pledged his own organization to establish a central, government bank. Bettmann  /  Contributor As Coughlins tirades became more extreme, radio networks wouldn’t let their stations broadcast his sermons. For periods of time he found himself unable to reach the vast audiences he once attracted. By 1940, Coughlin’s radio career was largely finished. He would still appear on some radio stations, but his bigotry made him toxic. He believed the United States should stay out of World War II, and following the attack on Pearl Harbor the Catholic hierarchy in America formally silenced him. He was forbidden to broadcast on the radio, and told to keep a low profile. A magazine he had been publishing, Social Justice, was banned by the U.S. government from the mails, which essentially put it out of business. Though once one of the most popular figures in America, Coughlin seemed to be quickly forgotten as America turned its attention to World War II. He continued to serve as the parish priest at the Shrine of the Little Flower in Royal Oak, Michigan. In 1966, after 25 years of imposed silence, he held a press conference at which he said he had mellowed and no longer held his controversial ideas from the late 1930s. Coughlin died at his home in suburban Detroit on October 27, 1979, two days after his 88th birthday. Sources: Coker, Jeffrey W. Coughlin, Father Charles E. (1891–1979).

Compare and differentiate Maoism and Stalinism Term Paper

Compare and differentiate Maoism and Stalinism - Term Paper Example The peasants and workers formed the revolutionary classes under this belief. Marxism-Leninism is a globally inclined ideology that was of the belief that the communist revolution was inevitable. It further advocated that once the revolution had happened in one country, then others will soon have their own revolutions. Thus, it was the duty of believers of Marxism-Leninism to try to export the revolution. Both Stalin and Mao tried to implement Marxism-Leninism in their countries albeit with some modifications to suit their present situations and personal convictions. The two leaders implemented â€Å"Five Year Plans† in their countries in order to spur development. Stalin’s First Five Year Plan (FFYP) begun early in 1926. His major focus was to transform the Soviet Union from an agrarian economy to a prominent industrial power. He argued that rapid industrialization was critical for the Soviet Union to flourish and survive as a world power. Stalin’s FFYP was prese nted as a Second Revolution and this helped him to mobilize the peasants as they perceived themselves to be in a class war with their previous oppressors (Keefe, 2009). Rather than follow Marxism-Leninism, the FFYP was a revolution from above; not from the masses. Stalin created a highly centralized command economy under the auspices of the State Planning Committee (Gosplan). The communist tenet of equality was disregarded as Stalin gave incentives to Managers and skilled workers. It should be noted that the FFYP put heavy emphasis on the heavy industry as massive resources were put in place to develop the oil and steel industry. Mao’s began implementing his First Five Year Plan (FFYP) in 1953. According to Friedman (2001), Mao’s core goal was to end Chinese dependency on agriculture and transform the country into an industrialized economy. Mao’s plan was very similar to Stalin’s since it also advocated for rapid industrialization so as to make China a wo rld power. The Chinese relied on the assistance of the Russians both economically and technically. Mao reorganized his administration to reduce bureaucracy and increase the country’s labor force. This move was aimed at reducing the chances of derailing progress due to a long chain of command. The peasants were required to diversify from agriculture to industrial work. Although the effectiveness of the First Five Year Plans for both leaders was questionable, they nevertheless went ahead to launch their Second Five Year Plans (SFYP). Stalin implemented his SFYP beginning 1933. This plan utilized the industries built during the previous plan to increase productivity. The Second Five Year Plan gave more attention to consumer goods unlike its predecessor. In retrospect, this plan was much more realistic and achieved considerably better results. After Mao’s FFYP, he implemented a much more audacious policy in the Second Five Year Plan. Mao believed that China would develop m ore rapidly if all resources were used to develop both industry and the agricultural sector concurrently. He utilized the country’s cheap labor to provide services primarily to the grain and steel industry. However, poor workmanship resulted in the failure of the steel production projects. The steel plants were poorly planned and there was scarcity of qualified engineers to oversee the work (Mark, 2001). In order to reign on the agricultural sector, both Stalin and Mao implemented the policy of Collectivization. Under Stalin,

Critically discuss the role of an HRD manager in promoting organizational competitiveness within a slowly recovering economy - Essay Example or a change and development among the organisational structure is mostly identified when the job performances of employees are not meeting the standards of the organisation. To be more precise, when the performances of the two groups working under same conditions do not produce the same outcomes, then the HRD manager has to step in the role for enhancing the employees’ performance. Career management and development, socialization and orientation, coaching and performance management are among the few factors that the HRD manager’s roles are surrounded with. It is therefore, necessary to identify the appropriate time to assist the management for developing organisational competitiveness. Thus, the objective of the paper is to identify the different roles played by the HRD manager, both necessary and unnecessary, which at times play a vital part upon organisational performance.

Impact of Guilds on Medieval Life Research Paper

Impact of Guilds on Medieval Life - Research Paper Example Guilds were the early associations of skilled workers that originated in the European countries – mostly, France, Germany, England and Italy – which had the written consent of the authority of their region to manage the workforce relevant to the requirements of job owners. Guilds had their advantages of working as collective union whereby ensuring employment opportunities to all the members with reasonable wages and social respect. They held high regards from the monarchs and clergymen for the unique knowledge they possessed for accomplishing the required merits at their desired fields of work. This essay focuses on the influence of guilds in industry, trade and economy across the world during the medieval period. Origin and Extend Guilds were probably the first organized group of individuals set for contributing money and effort towards a common goal in the history of mankind. They comprised the involvement of people from all walks of life which had the original root f rom the Anglo-Saxon civilization throughout Europe. According to Staley, as early as the period of Roman Empire, trade unions were formed with the association of men of similar age, interests, instincts and employment skills and trained for the purpose of the wellbeing and the moral guidance of the society (33). Early guilds were effectively trained by the trade schools for the military purposes and for the constructive requirements of kingdoms. Trained guilds were able to handle jobs in organized sectors, and most of them provided employment to individuals working from their homes. Organized activities of guilds had their influence greatly on the administrative sectors of revenue and merchandise in the early European economy. Since the ancient trade involved international transport of commodities, merchants had formed guilds that operated their business mainly through sea-routes. These trade gilds were the founders of sub-classes of business processes like wholesalers, retailers an d business agents in their domestic as well as international commerce. The foremost of all their achievements was the formation of colonies in foreign countries for the easy access to international business. A clear reference of the proceedings of the early merchant guilds focus the light to the centralized business management applications they employed in the international commerce. Some studies like that of Richardson show that these guilds had a strict regulation of a contractual relationship among members by which they were collectively responsible for the default of each member; and in case of the goods being forfeited at a foreign port for alleviating bad debts, the owner could claim for compensation from the actual defaulter at his home country. Craft guilds, on the other hand, focused on the promotion of particular trades and owned small work units that usually operated from home. Their basic segment of work related to conversion of agricultural commodities to consumable goo ds and their sales in the open market. Bakers, butchers and brewers were the most important category that held the profession in the consumer goods trade. More durable goods were the elements of manufacture guilds that produced goods and sold them in distant markets besides meeting the demands of the local buyers. Under the durable’

One example of a high EQ individual is my lecturer who is able to make every student’s response seem like gold or of Albert Einstein’s quality. On the other hand, an example of a low EQ individual would be my boss who constantly derides my every action and attempts to be excellent. I am left with the notion that it is impossible to achieve anything of substance. I believe that a high EQ can certainly help one’s personal and professional work. Likewise a low EQ can hinder one’s ability to progress. Firstly, a high EQ will cause one to relate at an optimum level with oneself as well as with others. Thus, one’s perception of self will improve to such an extent that others will want to be in the presence of such an individual. Similarly, a low EQ would cloud one’s ability to clearly accept oneself. Consequently, inability to objectively accept self will interfere with one’s ability to understand and relate to others. EQ therefore will affect both personal and professional life because one does not live in a vacuum. What affects one area of life will disperse to the other

Forum 5 criminology - Essay Example definition:- there is lack of a central repository for data on the actual number of corporate crimes in the state and all the federal courts of the United states. Secondly, the only source of data in the United States sentencing commission, this does not accurately reflect the problem as it only collects data on corporations that have been convicted of federal offenses ("White-Collar and Corporate Crime." Criminology & Public Policy 1.1 (2008). It leaves out the other firms who may be the actual offenders or committers of corporate crime. The other problem comes when it comes to the definition, this term is not a concisely defined term, and this leads to additional difficulty when it comes to the determination as to what types of behaviors would fall under the category of corporate criminal offenses. The problem of defining corporate law has happened over the years. This is because of the dynamic evolution that this form of crime takes. Corporate criminal laws take five forms ranging from the consideration of separate legality, followed by review of criminal cases by courts. Thirdly, we have the growth of the regulatory agencies and law to influence them, the next is the joining of forces is the corporations and the government to fight it and lastly a call for reform because of the rampancy of these crimes (HASNAS 2005). To curb these problems start by the clear identification of the problems. This is because a problem normally arise with the sanctions of the corporate crimes where if the guidelines significantly increase the sanctions, the substantial reductions in fines is allowed in the case with the evidence of an organizational due diligence. Another solution for corporate crimes is derived from the â€Å"Sarbanes-Oxley Act of 2002† which is characterized by mandated auditor independence and increased penalties for securities fraud and this makes corporate heads refrain from fraud of any form of their companies (Keane 1993).

The Life and Legacy of William Shakespeare Essay Example for Free

The Life and Legacy of William Shakespeare Essay Seven years later after their wedding, William Shakespeare was born in April 26, 1564 in Stratford (accepted birth and birth place) to Mr. and Mrs. John Shakespeare. William had eight siblings, and although he didn’t get a chance to meet all of them, they were still part of his family. Joan (Oldest Sister), the first child brought a huge amount of joy to the young, and ambitious couple, only to be dealt a dreadful blow shortly after her birth; On September 15,1558 Joan was baptized (only survived two months). Margaret (Older Sister), was born in 1562 and was baptized on December 2. Once again family life was devastated as the little Margaret only lived for one year. Two years after William’ birth, the Shakespeare’s fourth child, Gilbert was born. Gilbert was baptized at Holy Trinity on October 13, 1566, at Holy Trinity. He followed his older brother (William) to London where he established a good and successful career later in life. Joan (Younger Sister), was born in 1569, she was named after her oldest sister, Joan. She had a dissimilar childhood to her older brothers. She was known, like her parents, to be unable to read or write. Joans childhood would have therefore been close to the family and helping her mother with the chores. Anne (Youngest Sister), was born September 28 1571, when William was seven years old, Gilbert was five and Joan was two providing the three brothers and sisters with another sister. Another catastrophe struck the family in 1579 when little eight year old Anne Shakespeare died. Richard (Younger Brother), was born 1574 and baptized on March 11, when William was 10 years old, Gilbert was 8, Joan was five and Anne was three providing the four brothers and sisters with another brother. In 1578 his elder brothers were removed from school to help with the business and it is therefore doubtful that Brother Richard received much of an education. Edmund (Youngest Brother), was born in 1580, he was christened on May 3. He had four, healthy, living siblings; Brother William aged 16, Brother Gilbert aged 14, Sister Joan aged 11 and Brother Richard aged 6. He never had the chance to meet his other older sisters Anne, Joan (eldest sister), and Margaret. William Shakespeare Brothers Sisters. WILLIAM SHAKESPEARE. N.p., n.d. Web. 19 Dec. 2012.

Adaptive Wing Design For A Morphing Mav Biology Essay

Adaptive Wing Design For A Morphing Mav Biology Essay The wing design of a Micro Air Vehicle is to be designed to aid in the assessment of earthquake damage. The MAV is required only to be powered by an electrical motor, limiting flight time and endurance/range, and must be able to fly to the scene quickly and efficiently. Therefore, the analysis of the wing structure is two-fold: 1) having an efficient wing design for cruise (faster) flight and 2) having an effective loiter (slower flight) wing design. The main methodology in ensuring the optimal wing structure would be to design two aerofoils with an actuator which will morph the wing dependant on the different requirements. The software package DESFOIL, on the University of Sheffield intranet, is considered a friendlier user interface for the original XFOIL package created by MIT Professor Mark Drela to aid in the understanding of low speed aerofoil flow solution. However, since XFOIL contains a less than friendly interface, DESFOIL, a MATLAB based software, creates a friendlier user interface, enabling aerofoil analysis to be more easily understood. NACA Aerofoils Since NACA aerofoils will be the predominant choice in attaining the aerofoils for our MAV, this section will concentrate on providing a breakdown on the key aspects of such aerofoils. The 4 digits associated with the NACA aerofoil provide information as to the physical structure of the aerofoil. The four digits are broken up as such The first number offers information about the maximum camber as a percentage of the chord length. The second digit provides information as to the position of this maximum camber as a function of the overall chord length (in tens of units) The final two digits provide information on the maximum thickness of the aerofoil as a percentage of the overall chord length, as a percentage. Thus, it can easily be seen that the chord length is pivotal in determining the correct NACA aerofoils. Centre of Pressure and Aerodynamic Centre Other important aerofoil characteristics are the centre of pressure and aerodynamic centre. If we consider them individually, we can attain a clearer picture of their importance. Starting with the centre of pressure, it is known that the positioning of this point changes with lift, namely it moves towards the leading edge as lift increases. However, using this same theory, it can be understood that this centre of pressure can move outside of the aerofoil geometry. More specifically, at low levels of lift generation, the pressure centre can be behind the aerofoil. Such a parameter is important to understand since it allows for trimming of the potential aircraft on which the aerofoil will be mounted. The centre of pressure can be calculated using calculus provided a pressure distribution is understood. Since we are dealing with a distribution, the length of the chord becomes increasingly important and it is normal to talk about the pressure as a function of chord length, generally starting with the leading edge. The aerodynamic centre contains a more direct link with the stability of the aircraft/aerofoil. The aerodynamic centre is the point on the aerofoil where the pitching moment of the aerofoil is independant of the angle of incidence. Understanding of this point is crucial due to its large contribution to the balancing and therefore stability of the aerofoil/ aircraft. Since the majority of aerofoils which will be considered within this journal are cambered, it is interesting to note that the aerodynamic centre is approximately situated at a point  ¼ of the chord length. Drag When considering drag, the main thought is of a retarding force to motion in a certain direction. The relationship is simple; the greater the drag (retarding) force, the greater impedance on motion. From an aerofoil design point of view, we wish for such force to be as minimal as possible since a lower retarding force allows faster speeds (longer endurance and/ or range) and more efficient flight. To understand more about drag, we need to understand more about the different components of the force. If we can understand the forces main constituent parts, this may help us lower the drag our aerofoil experiences. The drag force can be broken up into several different components. Some of these are Parasitic drag Lift induced drag As we will later calculate, the lift our aerofoil produces will vary depending upon which flight attitude regime we are in i.e. loiter or cruise, and thus the drag each regime experiences will vary. Since this is important in understanding how the aerofoil will react to regime changes, the lift induced drag will be looked at more closely within this analysis. The concept of parasitic drag is broken into many different parts. Such constituent parts include skin friction and pressure drag. The concept of skin friction comes about due to the interaction of fluid molecules contacting the surface of the aerofoil, bringing local wall shear stresses into consideration. It can thus be seen that the faster the motion of molecules past the aerofoil, the larger wall shear stress. The skin friction coefficient shares an inverse parabolic relationship with the speed of the aircraft The contribution from pressure drag will be considered in terms of flow separation points further into this report. Such drag will take precedence in the analysis of drag within this report since it provides a more rigorous depiction of the drag at different angles of attack and different DESFOIL accuracy parameters (panel number). Since DESFOIL offers only this type of drag, it will be assumed that this pressure drag is the overall coefficient of drag, when discussing analysis of graphical data. This is a reasonable assumption since the drag values and pressure distributions compliment each other. Furthermore, since we will later consider the 3D effects of the aerofoil, it is important to note that there will be different drag factors which will increase the amount of drag experienced by the aerofoil. A major form of drag which the aerofoil will experience while in flight is the vortex drag, more specifically the drag due to the mismatch of pressure along the upper and lower surfaces of the aerofoil. More specifically, this drag arises due to an overspill of high pressure on the lower surface of the aerofoil to the upper surface, which is abundant in low pressure areas. Thus as the aerofoil moves through the fluid, in our case air, this overspill will manifest itself into tip vortex, increasing the drag experience by the aerofoil. Thus, although only drag will be termed in this journal, there may be separate underlying factors involved. 3D and 2D Calculations Although DESFOIL is only applicable to 2D aerofoils, adjustments can be made such that the results from DESFOIL can be used within 3D situations. Since we are designing an actual aerofoil, such considerations need to be taken into account, and are during the later parts of this journal. The importance of using such a program lays in its simulation of the aerodynamics the aerofoil experiences. Therefore, using such a program allows the possibility to determine what coefficient of lift (or, 2D and 3D analysis respectively) and coefficients of drag, subscriptd, or D accordingly, are needed for optimal flight. As we will determine in this report, optimal coefficients will be calculated and a wing structure designed accordingly. Design Brief The following reading is an analysis of the software package DESFOIL on the suitability of difference NACA 4 digit aerofoils on an MAV of certain design specifications. These include Cruise Speed, = 15 Loiter Speed, = 8 Wing Area, S = 0.13 We will assume a rectangular planform for our aerofoil. Furthermore, we will assume the aerofoil as the main form of lift, i.e. neglecting fuselage, tail plane or rudder lift generation Wing Characteristic/ Structure Lift is defined as the aerodynamic force that a surface produces in the presence of a perpendicular velocity vector. Since lift is defined as a force, , we can assume that lift is some function of the density of the medium it is produced within, , the size of the object producing such a force, , and the before mentioned velocity, Therefore, (1) Where x, y and z are unknown parameters defining the relationship outlined in the equation. Through dimensional analysis we can deduce the values of such unknowns. (2) (3) In terms of lift forces, the constant of proportionality is termed the coefficient of lift, deriving the lift equation (4) It is also possible to consider a more rigorous analysis of the coefficient of lift taking into account symmetrical and cambered aerofoils, which yield and respectively. However, such equations only apply to thin aerofoils and since the thicknesses of the aerofoils are unknown in this assignment, the generic formulae will be used. Similarly, derivation of the drag forces can yield an equivalent drag version of equation (4). (5) To deduce our optimal lift coefficient, we will assume the lift generated will equal the weight of the aircraft, a reasonable assumption when considering straight and level (cruise) flight and the loiter regime. Therefore, the lift coefficients can be calculated for the respective flight conditions (6) Equation (6) yields a cruise coefficient of lift of 0.285, while similar analysis for loiter conditions yields a lift coefficient, of 1. Since we are initially more concerned with the wing aerodynamics with respect to wing structure (aspect ratio), we will consider the induced drag, , whereby, (7) Where e is the Oswald efficiency of the aerofoil, a correctional factor added since the wing shape differs from the elliptical wing used for the derivation, and A is the aspect ratio, calculated by the length to width ratio. To select the best aspect ratio for our aerofoil, the induced drag variation with aspect ratio changes is shown in Figure 1. It can easily been seen from Figure 1 that an aspect ratio of 5 would be acceptable since there is negligible variation in terms of the two dimensionless concepts. However, if we consider this in terms of the actual MAV, an aspect ratio of 5 would yield a span of 0.8m and a chord length of 0.16m. Evidently, while this is the longest and thinnest allowed in this particular investigation, possible structural problems may occur. However, if we consider the capabilities of the aircraft, there are advantages too. As Figure 1 has shown the induced drag in flight would be decreased, enabling better endurance and longer range. The structural instability could be overcome by careful selection of materials and designing of the structure. Thus, although problems may arise from such an aspect ratio, these problems can be overcome and do have their own advantages. Such data allows calculation of cruise and loiter Reynolds number and Mach number to be calculated. Figure 1: Induced Drag and Aspect Ratio relationship (8) (9) Similarly, and. Panel Number Since DESFOIL is the primary tool in determining which aerofoil will be used and its aerodynamic characteristics known, it would be wise to research the capabilities of the software and which system (panel number) to use to ensure the results obtained are of relevant accuracy. Another important aspect of using DESFOIL is the time taken for results to be determined. This will be analysed next. If we consider the effects of panel number on the lift, drag and pressure distribution respectively, we can clearly see a relationship shown in Figures 2, 3 and 4. Considering an angle of incidence of 10 degrees, it is evident to see that the most accurate results come about with the higher panel numbers. Since the maximum panel number within DESFOIL is 280, it would seem this would be the optimal choice. However, upon closer analysis, it is the time taken for such accurate results to come back from the software, which is of greater importance. For example, a panel number of 280 will provide the most accurate answer, but also take the longest to deduce. Therefore, if we consider the (negligible) variation of values, we can deduce that a panel number of 180 is significantly lower, thus, allowing quicker results, but still retains a high level of accuracy. For example, for the lift coefficient, 180 yields 1.0012, while 280 yields 1.0028. Thus the accuracy difference is negligible. Figure 2: Variation of Lift with different panel number on NACA0012 aerofoil Figure 3: Variation of Drag with panel number on NACA0012 aerofoil When analysing the pressure distribution, fewer panel numbers were considered, since the graphical representation would have become severely hard to differentiate between the different graphs. On the other hand, the before mentioned negligible differences is perhaps clearer in Figure 4. With the panel number at 280, the pressure distribution is most smooth, allowing finer details to be seen, which would otherwise be lost in lower panel numbers. Thus, a panel number of 180, the lowest without losing significant accuracy, is optimal. Figure 4: Variation of Pressure Distribution with panel number on NACA0012 aerofoil Reynolds/ Mach number So far, we have considered only the cruise aspect of the MAV. Since the aircraft will experience loitering stages also, analysis must be considered into different Reynolds and Mach numbers. Both of these are necessary in understanding the aerodynamics of the aerofoil since they both alter the way in which the aerofoil will react to airflow. For example, consideration of transition points, the onset of turbulent flow, boundary layer thickness and laminar flow needs to be understood to optimise the aerofoil design. Therefore, changes in the behaviour of the aerofoil/ airflow must be modelled and simulated within DESFOIL. For further understanding of such phenomenon, XFOIL will be used to pictorially show the effects of Reynolds number and Mach number on boundary layer, amongst other sets of information. More specifically, larger Reynolds and Mach numbers will be taken into consideration to visualise compressibility effects. To observe such results, i.e. how changes in density with regards to the pressure distribution, comparisons will be made to show how the compressibility effects (large Reynolds/ Mach number values) alter the characteristics/ performance of the aerofoil. An angle of attack of 10 degrees was considered when undertaking the computations in all examples. Incompressibility/ Compressibility Effects Figures 5 and 6 visually show the variation of the boundary layer with a high Reynolds and Mach number. If we consider Figure 5, we can see the specific values of coefficients of lift, drag and pitching moment at the angle of attack mentioned before. Another helpful mode shown within Figure 5 is the description of the change in boundary layer over the length of the chord of the aerofoil. This pictoral view shows the general formation of turbulent flow from laminar flow. As will be seen later in the report, there is a relationship between the boundary layer thickness and the Reynolds number. This relationship is important to note since a thinner laminar boundary layer ensure lower drag. Again, this concept will be further investigated later. Figure 5: XFOIL graph showing pressure distribution along aerofoil Figure 6: XFOIL graph showing variation of other aerofoil characteristics Reynolds Number Mach Number Cl Cd lift/drag 1000000 0.4 1.083 0.01965 55.13 169412 0.04 1.0266 0.03469 29.59 90353 0.024 0.9415 0.05289 17.8 Figure 7: How lift and drag vary with different Reynolds and Mach numbers From Figure 7, we can see the direct impact the differing Reynolds numbers and Mach numbers have on the generation of lift and drag. Quite clearly, as the Reynolds/ Mach number decreases, so does the coefficient of lift, and thus lift generated. Also of significant importance is the increase in drag with decreasing Reynolds/Mach number. Due to these variations, the lift to drag ratio also decreases. However, it is important to note that the results are non-linear. This non-linearity can be explained from the transition from incompressible flow to flow whose density changes with respect to the pressure distribution. Thus, such characteristics cannot be extrapolated or calculated; they must be experimentally defined, or computationally simulated, since consideration of compressibility effects adds complexity to calculations. Boundary Layer Analysis Although there is little difference between the values of lift coefficients (in the first two examples), there seems to be a drastic difference between the lift: drag ratios. Since the coefficients of lift are similar, varying by less than a magnitude of value, the only possible change must come from the drag experienced on the aerofoil. Experimental data, treating the aerofoil as a flat plate, shows that as the Reynolds number increases, the boundary layer thickness decreases, shown in Equation (10). (10) Thus, a decrease in the Reynolds number causes a larger boundary layer around the aerofoil, which in turn causes a greater disturbance to the free stream air. Since the boundary layer cannot handle a large adverse pressure gradient without separation, the higher values of Reynolds number cause separation earlier, even though they have thinner, boundary layers. This is due to greater adverse pressure gradients which are responsible for the larger values of lift coefficients attained. The separated flow causes larger amounts of drag, which is obviously undesirable, since the flow is no longer uniform along the chord. Once the pressure gradient exceeds a critical point, the boundary layer will separate from the aerofoil, therefore reducing the magnitude of the pressure gradient, reducing lift generation. Therefore, the lift: drag ratio decreases as drag will increase upon separation. The drag experienced at higher Reynolds numbers is still considerably smaller than the drag experienced at lower Reynolds numbers due to the thickness of the boundary layer. Although separation of the flow is a factor with regards to drag, the boundary layer thickness, as seen in Figure (7) using Equation (10), is a larger factor. Since this separation point (transition from laminar to turbulent flow) is an area of interest with regards to the amount of drag experienced by the aerofoil, Figure 8 shows the movement of such a point with regards to the Reynolds number. The black lines only show the separation points on the upper surface of the aerofoil since this is the surface of most interest. Figure 8: Transition point. 1) Re=1000000, M=0.4 2) Re=169412, M=0.04 3) Re=90353, M=0.024 At this point it is important to note that the DESFOIL parameters were changed to ensure a completely accurate result from the simulation. To ensure the accuracy was maximised, the transition detection was 100% the length of the chord, and not simply the default 20%. This allowed DESFOIL to look throughout the whole length of the chord for the transition/ separation point as opposed to the default 20%. As we can see, for the same angle of attack, the higher Reynolds/ Mach numbers cause the separation point to be significantly closer to the leading edge. Similar XFOIL graphs were constructed as that in Figure 6 for the other Reynolds/ Mach numbers. From Figure 6, we can see that at an angle of attack of 0 degrees, there is a separation point at 0.637, i.e. 63.7% away from the leading edge as a function of the chord length. When the Reynolds number is 169412, this separation point is 91% as a function of the chord length, while the loiter Reynolds number remains laminar at 0 degrees angle of attack. Geometries If we consider other three dimensional geometries with respect to the drag each produces, we can understand why an aerofoil is an optimal shape in terms of reducing drag. Figure 9: Drag values for various 3D geometries If we consider streamlining any given shape, we can possibly reduce the amount of drag experienced, as shown in Figure 9, by an order of magnitude. For example, if we consider the sphere, hemisphere and teardrop shapes, although all have the same frontal geometry, it is the streamlining of the teardrop which contributes most to a significant reduce in drag, due to the prolonged attachment of the airflow. Since the airflow after the sphere/hemisphere is suddenly separated (due to the non gradual geometry behind the shape), there is a significant amount of drag experienced. This is why Figure 5 depicts such a prolonged attachment of the airflow, only becoming separated towards the trailing edge of aerofoil. To further reinforce the advantageous effects of streamlining, Figure 10 shows the geometrical differences which can be obtained with intelligent streamlining. Figure 10: Two different geometries with the same aerodynamic drag force Lower Aerofoil Surface Another important feature found from graphs similar to Figure 5 highlights the relationship between the angle of attack, Reynolds/ Mach number and flow over the lower wing section. It was found that at lower Reynolds numbers, the flow is relatively laminar across the length of the chord length. This makes sense at high angles of attack since the underside of the aerofoil has a larger wetted area. Possible further investigation and research may lie in determining the flow over the lower surface of the aerofoil in negative angles of attack. Perhaps such an investigation will help understand the landing/ descending section of a flight path. It may be interesting to learn whether separation points play such a major role on the lower surface as they do on the upper surface, in terms of lift and drag. Such understanding can provide insight into painting a complete picture of the airflow surrounding a wing. Furthermore, since a NACA0012 aerofoil was considered giving all the results mentioned previously, changes in airflow with varying NACA aerofoils could help determine a more complex relationship. For example, as thickness, camber and camber position change, how does the transition point vary on the underside of the aerofoil? Such variations are made within the next section with regards to the overall lift and drag. However pressure variations could be conducted in a similar fashion. Designing using DESFOIL Since DESFOIL allows the user to design, test and evaluate their own chosen design (one of the many reasons it was chosen for undertaking of this particular investigation), it is important to understand how the different parameters affect the aerofoil characteristics. From this, we can deduce what the optimal aerofoil for our application could be. Furthermore, it allows for reinforcement of aerodynamic theory into the reaction of airflow over changing geometries of aerofoils. This could be seen as a measurement of DESFOILs accuracy in its simulations. If its simulation results were to vary from known aerodynamics, then the softwares validity would be questionable. Throughout the analysis, therefore, the aerodynamic theory will be called upon to explain the results given from DESFOIL. Since the software allows for three different design features, it was deemed necessary, to gain a full understanding, to adjust and examine one parameter at a time and comment on the results obtained. Since different values of lift were optimal for the different stages within our flight path, both the cruise and loiter conditions were looked at. From the template aerofoil NACA0012, the thickness was the first parameter to be changed. Figures 11 and 12 below graphically shows the variation in lift and drag over the four different aerofoil thicknesss chosen. Cruise Conditions Figure 11: Lift variation with different NACA aerofoils thicknesses Figure 12: Drag variation with varying thicknesses Firstly, the cruise conditions will be investigated. As we can see from the figures above, the thickness of the aerofoil plays an important role in determining such characteristics as stall angle and maximum coefficient of lift. If we consider both graphs simultaneously, we can deduce the thicker the aerofoil, the greater the values of lift can be obtained. This is shown with the increase in coefficient of lift values from 12% thickness to 15-21% thickness. This is down to the curvature of the aerofoil being the main form of lift generation, i.e. the more curved (thicker in this instance since camber position is constant) the aerofoil, the larger amounts of lift generated, within limits. Also, nose shape effects help the generation of high lift coefficients. Furthermore, it is important to note that the thinner aerofoil has also stalled significantly harder than the thicker aerofoils. Since stalling is undesirable, perhaps thicker aerofoils would be best for use in the chosen aerofoil. Concentrating on the graphs from a drag point of few, we can again see that thinner aerofoils are undesirable due to the drag they produce/ experience. The sharp rise in drag experienced by the thinner NACA0012 aerofoil is complimentary of the stall it experienced at an angle of attack of 13. Furthermore, it is important to note that there are slight variations in the small angle of attack region with respect to lift and negligible difference in the corresponding drag section. Since a definitive relationship was deduced from the thickness investigation, it was reasonable to continue the designing experiments. Next, the camber thickness was investigated. Figure 13: Lift variation with angle of attack with different camber thicknesses Figure 14: Drag variation with angle of attack with different camber thicknesses From the above figures, certain relationships can be deduced between the camber thickness and the effect such parameters have on the lift and drag experienced on the aerofoil. Firstly, lets consider the adverse effects on the lift and drag, shown here by the NACA-2012, whereby the -2 denotes a negative camber. From Figure 13, we can see a significantly lower lift attained flight with an earlier stall, which compliments Figure 14, whereby the drag significantly increases due to the separated flow resulting from the stall. For the other three aerofoils shown, the aerodynamic drag force experienced by each has negligible difference, since all follow the same shape. The differences can more obviously be seen through analysis of Figure 13. Here, we can see the larger the camber, the greater values of lift can be obtained. However, it is important to note that only the NACA4012 aerofoil does not experience a stall. On the other hand, the other two positive aerofoils, while although experiencing a stall, do not stall extremely harshly, and so a stall of this kind, while although not optimal, can be considered negligible in terms of lift generated. The camber position was investigated next Figure 15: Lift variation with angle of attack under different camber positions Figure 16: Drag variation with angle of attack under different camber positions As we can see from the above two figures, the effect of camber position is not as drastic as the other previous analysed parameters. From Figure 15, we can see the highest lift is attained by the NACA4212 aerofoil, although all the aerofoils have the same similar low angle of attack lift generation. It is only towards angles of attack greater than 7 where there is greatest deviation. On the other hand, it can also be seen that the NACA4212 aerofoil, while giving the highest lift value, also stalls. As mentioned before, this is undesirable. From a drag perspective, the NACA4212 aerofoil performs best towards larger angles of attack however performs worst at low angles of attack. Depending on where the greatest emphasis needs to be placed upon the cruise aerofoil conditions, this may be an important factor. Chosen Cruise Aerofoil Since we have analysed the effects of the three different parameters within DESFOIL, we can now evaluate what lift and drag characteristics we want from our chosen aerofoil. Since the actual aerofoil will be 3D, we need to take into consideration 3D effects. For this instance, we are going to assume the 3D coefficient of lift is 90% of the 2D coefficient of lift, namely, (11) One reason there is a decrease in the change from two dimensional to three dimensional bodies is the appearance of an extra plane, i.e. the z plane. Thus, the lift generation needs to distribute the lift over three planes instead of two. Thus resulting in less lift overall. Therefore, we can calculate a coefficient of lift of 0.3167 to be found using DESFOIL. Taking what was found from the above investigation, various NACA aerofoils were tested. The final aerofoil chosen was the NACA2615 aerofoil for reasons clearly shown using Figure 17. Figure 17: NACA2615 aerofoil characteristics From this figure, we can see the optimal design characteristics we want from our cruise aerofoil. These characteristics include a significantly low drag, as compared to the lift generated, which can be seen as a direct result of no stall being present. Furthermore, if we consider the lift we wanted to generate, namely 0.3167, we can see this aerofoil manages to attain such lift at a low angle of attack, something we want from our aerofoil since the quicker the optimal lift can be generated, the quicker the aerofoil will start behaving to optimise its performance. Since this optimal lift is generated at an angle between 1 and 2, the lift: drag ratio was calculated for these two angles. They are 17 and 39 respectively. These high values show the positive performance of our aerofoil in the cruise condition. Loiter Condition As we can see from the previous section, a detailed investigation and analysis was undertaken to establish the best NACA aerofoil for our cruise purposes. If we now go on to consider the loiter condition, there are certain parameters which need to be considered, namely the 2D lift we wish to aim for, at the lowest angle of attack, to find the optimal aerofoil. As shown in the previous section, the thickness, camber and camber position were all varied individually and the resulting effect on the lift and drag analysed. Using Equation 11, we can calculate the required lift (needed to be found in DESFOIL) as 1.11. Firstly, the thickness was adjusted. It was found, just like the cruise condition investigation that an increase in thickness resulted in higher levels of lift being attained. However it was also found that the aerofoils under loiter conditions tend to stall, regardless of thickness. However, the greater the thickness the higher angle of stall. Since all aerofoils tested stalled, the drag associated with each was indicative of this phenomenon. It is also important to note that the aerofoils tested were the NACA0010, NACA0012, NACA0018 and NACA0021. Considering the position of maximum camber next, it was found that the NACA4212 aerofoil stalled significantly earlier than the NACA4012, NA
