Wendy's Hamburgers Case Study Example | Topics and Well Written Essays - 1000 words

Wendy's Hamburgers - Case Study Example His desire to control his life and business is a good illustration of some of the basic entrepreneurial traits. Also, he has demonstrated open mindedness and innovation traits when decided to open burger restaurant with new innovative and creative ideas. When he has made a decision to shift to hamburgers, he made a decision to shift to the thing which he really liked. In such a way he has demonstrated his passion to do what he loves. Despite the skepticism and negative forecasts of experts he has made a decision to move forward with his idea. Thus, Dave has demonstrated optimism and belief in himself and his expertise, which is also critical for successful entrepreneur. 2. Dave’s success with the first Wendy’s restaurant can be attributed to an idea to offer fresh hamburgers of high quality. This was something new as the competitors offered hamburgers made from a frozen meat. Even though the market was saturated he has managed to find a unique selling point or the so called competitive advantage, which enabled his business to develop and grow despite fierce competition on the market. It is possible even to suggest that he has broken some stereotypes, as fast food is usually associated with bad quality and unhealthy food. Thus, fresh high quality fast food offered in Dave’s restaurant has contributed to shift in consumer’s perceptions about fast food. He has managed to satisfy customers’ needs and even exceed their expectations, making the restaurant profitable within the first weeks after the opening. 3. The phrase about the most difficult thing in running business is â€Å"being willing to listen to customers then doing whatever it takes to make your dream (and their wants) a reality† could be interpreted as Dave’s vision of his role as an entrepreneur. Dave is an entrepreneur who pursues his own dream, and chooses optimal

Essay quiz Example | Topics and Well Written Essays - 500 words - 1

Quiz - Essay Example In broadest possible terms, metaphysics traditionally tries to answer a couple of basic questions: What is out there in the realms of the unknown? What is the nature of that unknown or how does it look like? A philosopher generally tries to answer these questions for general people and broaden their view about the world; for example, possibilities, cause and effect, time and space, object and their properties, and also existence. Ontology is the central branch of metaphysics that investigates the basic categories of being and their relations. Cosmetology is the other branch of metaphysics that studies the origin, nature, dynamics and fundamental structure of the universe (Capaldi, 1997). Sometimes epistemology is also considered as a central branch of metaphysics. However, it is not confirmed. As far as the â€Å"Sceptical Doubts† is concerned, there are two thinking styles or types of knowledge. Those are matters of fact and the relations of ideas. Hume believed human knowledge is either necessary or contingent. Secondly, it is an ultimate truth that there should be relations between ideas. Thirdly, matters of fact are considered as contingent truth. The inherent logical contingency does not allow inductive predictions and statements of matters of fact to amount to knowledge (Capaldi, 1997). To prove this point, Hume states that the sun will surely rise tomorrow like it does every day, and it would be absurd to think that sun will not rise the next day. With this alternative concept, metaphysics can serve as a foundation for the nature of reality but not as such for reality directly. Metaphysics offers most basic accounts that are related to the nature of things like what they are and not of things like how they are. As a step to answer the first question – we need to first differentiate between the two ways in which a statement

The Benefits of Hybrid Cars Essay Example for Free

The Benefits of Hybrid Cars Essay There was once a time when you could turn on the news and not hear about the terrible state of the environment or the impending doom that is global warming. That time has become part of the past. The standard automobile can be blamed for a large portion of the conflict. Today’s large gasoline engines spew harmful emissions into the air every time we drive. Of course as a result, the United States government has started to resolve these problems. As a result, the United States government has been attempting to solve the environmental problem. One such solution is the hybrid electric car, which can save resources by giving off less emission. And my claim is one of the ways to assist the environmental situation is using hybrid cars. First of all, what do we know about the hybrid car? HEV’s or hybrid electric vehicles differ from standard vehicles by their source of power. According to Michael Westbrook, who is recently retired as the manager of technological research with the Ford Motor Company, â€Å"any vehicle that has more than one power source can be classified as a hybrid electric vehicle (HEV)†(142). The first-ever hybrid cars appeared in the middle of the nineteenth century. These primitive constructions sped up no more than 10 km/h (Westbrook, 11). The main energy that propelled vehicle was steam source. In 1905 Belgian, Henry Pieper, invents and patents a hybrid chart for a car. Ferdinand Porsche developed the idea of the Belgian inventor. A car carried the name Lohner Porsche and was very popular at that time. Company Lohner Porsche produced a few varieties of hybrid cars of the most different orientation: freight, automobile, busses, fire trucks and ambulances. But unfortunately, in 1906 production of hybrids of System Lohner Porsche was stopped from their unprofitability as compared to cars on petrol. A new wave of interest in the hybrid vehicles emerged after 40 years, in the early 60’s, last century. But it was just the beginning of an interest in hybrid vehicles (Westbrook, 20-21). Permanent price advances on oil and gas in the late twentieth century, and also strengthening of requirements to ecological descriptions of cars, have compelled developers again to take up developments of ecofriendly and economical motor vehicle. (Westbrook, 23) After a long time, the forgotten ideas of hybrid auto were needed designers. In 1997, Toyota began selling the Prius. Below is the example of two hybrid cars from different manufacturers. (Siler) After two years, another Japanese company Honda produces a hybrid vehicle, which is called Insight. This car satisfied not only the Japanese market, but the US too. But already in 2000, The Toyota Prius went on sale begins to expand to foreign markets, primarily in the United States. It was a huge success. According to the magazine Forbes The Toyota Prius enters in the ten cars that changed the world and also as the most sold hybrid car in the world (Westbrook, 26-27). In the meantime, due to the progress of hybrid cars and due to the high standards to automobile companies the situation with air pollution significantly changed. The chart below shows six major air pollutants and in the first place is carbon monoxide, which is emitted by vehicles, then nitrogen oxides, then volatile organic compounds, etc. (Cooper) But we should mention that comparisons from 1970 to 2002, the carbon monoxide in the air is so much decreased, and the reason for decreasing carbon monoxide is the hybrid car, because as we remember from the history of the hybrid cars in these years were the main progress in the development of hybrid cars. (Cooper) According to Nurretin Demirdoven’s investigation, which is the professor of Engineering System Division at the MIT, comparing the energy potency of hybrid and fuel cell vehicles, as we have with combustion engines, showed that fuel cell vehicles don’t provide more important benefits than hybrid-powered vehicles in urban vehicles in urban driving settings. There are other pros of using hybrid electric vehicle, such as: 1. Cost effectiveness. Hybrid car uses less fuel, as is able to move only the electric range by battery power. 2. Ecological compatibility. Intermittent use of ENGINES is ensured, while the electric motor does not produce harmful emissions into the atmosphere. Toyota Prius to 85 percent less polluting than the class car with traditional power installation. 3. Low noise. Electric motors are virtually silent. Hybrid car has its drawbacks: 1. High cost. For modern technology, environmental friendliness and cost efficiency car buyers have to pay the price for its purse. 2. The complexity of repair and insufficient development of a network of service centers in selected countries. 3. Potential danger to pedestrians who often just dont notice because they are hybrids of noiselessness. (YouManitoba) Hybrid cars are good for the environment. Hybrid cars are one among the promising types of new generation cars. Hybrid cars are more reliable than electric cars from what we are seeing to date and they have gasoline as an alternate fuel. Hybrid cars are currently more expensive to buy than conventional cars. So, we may pay more now but we should see great gains and thus yields is solving our current and long term energy needs when it comes to our people mover desires. Hybrid automobile technology has been accepted as an answer for the car pollution issues of the day. And in the end, I would like to conclude by quoting Gandhi: à ¢â‚¬ If you want to change the world, start with yourself.† Let’s change the world!

Intellectual Property and Copyrights Issues in China Essay -- Software

Intellectual Property and Copyrights Issues in China 1. Introduction China had made great improvement in deregulation and had complied with its obligations to follow rules and agreements such as Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) as a new member of the World Trade Organization (WTO) since 2001. TRIPS introduced intellectual property rules into the multilateral trading system. It ensures that computer programs will be protected as literary works under the Berne Convention and outlines how databases should be protected under copyright section. As the rush to riches continues to gain pace, people's legal right to own private property is protected by a law. However, Intellectual property and copyrights still remained inadequate to control over its booming internet population in China. Before we get into copyright status in China and ethical issues, clarification of terminology will help us to understand copyrights issues in software and differentiated other issues involving intellectual properties. 1) Classification of software  ·Commercial  ·Shareware  ·Freeware  ·Public Domain In terms of restrictions and limitations, each classification is different. Commercial software can be purchased from software publishers, computer stores, etc. When you buy software, you acquire a license from the company that owns the copyright to use it not own it. Although one archival copy of the software can be made, the backup copy cannot be used except when the original package fails or is destroyed. Shareware has same restriction as commercial software except that the copyright holders allows you to make copies of the software, but you must pay if you adopt it for use after testin... ...ies put effort to enhance confidence of foreign investors to protect intellectual property rights and recognizes illegal piracy actions. 5.

Lockheed Tri Star

Investment Analysis and Lockheed Tri Star Problem Sets February 25, 2013 1a. The results of NPV, payback and IRR calculations are the following. For payback method, Rainbow Product will pay back the original investment costs after 7 years. Net Present Value is -$946 and IRR is 11. 49%. Rainbow Products should not purchase the machine according to the results of NPV and IRR calculation. The net present value of purchasing this new equipment is negative, and the internal rate of return is less than the cost of capital; thus both calculations confirm that the investment will not provide additional value to the company.Of course the payback method shows that the instrument will have paid back the cost in 7 years but does not take into consideration discounting present values. 1b. If Rainbow accepts the â€Å"Good As New† service plan, net present value will be a positive $2,500 and IRR will be 12. 86%, greater than the cost of capital. The investment would also pay back the cost i n 8 years. Rainbow should purchase the machine under this service plan as it results in a positive net value and the internal rate of return is greater than the cost of capital. c. If Rainbow chooses the reinvestment option, net present value is $15,000 and IRR is 15. 43%. Therefore, the best investment decision is to accept option C, where engineers reinvest 20% of the savings that help cash flows grow 4% in perpetuity. Figure 1 (applicable to question 1a~1c) 2. Using the IRR rule, I recommend renting a larger stand as it yields the greatest rate of return. Using the NPV rule, I recommend building a larger stand.IRR rule can be misleading in this case as this problem is comparing 4 mutually exclusive projects and given the stats, IRR for one out of four of these projects yields a much higher value, but none of these IRR values take discounting rate into consideration. Therefore, NPV is a better method. Figure 2 3. The NPV of this project is $100,000. 1,100 shares of common stock sh ould be issued at the current price of $100. Issuing new stocks will increase shares of the stock in the market and therefore reduce the value of the stock of existing shareholders. Lockheed Tri Star Case QuestionsAt 210 unit production levels, the true value of the Tri Star program is negative $584. 04 million. At break-even production of 300 units, Lockheed actually lost roughly $274 million. At around 400 production units, Lockheed would achieve economic break even. The decision to pursue the Tri Star program was unreasonable due to a miscalculated break even point. At 210 unit production, the net present value was roughly negative $182 million referring that Lockheed would have needed to produce somewhere between 210 units to 300 units to achieve true break even.In addition, given the overly optimistic 10% growth rate that calculated double the total of true aircraft market, Lockheed would have needed to either capture more than 50% of the market for aircraft to breakeven. Betwe en 1967 and 1971, the price of Lockheed’s common stock dropped about $50. With 11. 3 million shares outstanding, this comes to about -$565 million. We see that the original NPV with 210 unit production results in about similar value as the drop in the total value of the common stocks outstanding.
