The Five Generic Competitive Strategies free essay sample

There are five generic business strategies that companies choose from when trying to successfully compete within their respective industries. This is the first choice a company must make, even before deciding an overall strategy. These generic business strategies include low-cost provider strategy, broad differentiation strategy, best-cost provider strategy; focused strategy based on low costs, and focused strategy based on differentiation. These strategies have many advantages as well as disadvantages. Choosing which one to use depends on what market position a company wants to pursue. Deciding to be more offensive or defensive also plays a role in choosing a business strategy. Some of these strategies are focused while others appeal to a broader spectrum of customers. These strategies can also be combine which allows a company to be even more competitive or to appeal to a new customer base (Thompson, Strickland, Gamble, 2010) Companies can also choose to start with one strategy and switch to another one to achieve a business turnaround. We will write a custom essay sample on The Five Generic Competitive Strategies or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Although many companies use the same strategy, no two companies will ever really have the same business strategies. This is because of the countless unique variations that can be added by each company, which can yield as many business strategies as there are businesses. (Generic Business Strategies, 2010) The low-cost provider strategy is setting a lower price than the competitors while trying to appeal to more customers. This strategy is very powerful in a market where there are price sensitive buyers. When companies strive for cost advantage over their competitors, they must include special features and services that buyers consider essential. (Thompson, Strickland, Gamble, 2010) Also, this strategy can be very prevailing when demand is price elastic; all firms the industry produce essentially the standardized products; there are not many ways of achieving product differentiation that have much value to buyers; most buyers utilize product in the same way; and buyer incur few switching costs in changing from one seller to another and thus are strongly inclined to shop for the best price. Generic Business Strategies, 2010) Trying to be the industry leader in achieving an overall low cost position entails being beating out competitors in building the most efficient plants, implementing cost-reducing technological advances, in getting the sales and market share needed to capitalize on learning and experience curve effects, in maintaining a tight grip on overhead and other administrative types of fixed costs, and in containing costs in such areas as research and development, advertising, service and distribution. By doing this, there are many advantages to using the low-cost strategy. Some advantages include: having the best position to compete offensively on the basis of price; having partial profit margin protection from powerful customers; being more insulated than competitors from powerful suppliers if its greater efficiency allows more pricing rooms to cope with increases in the costs of purchased material; and being in a favorable position in regards to barriers to entry. (Generic Business Strategies, 2010) Although there are many advantages to using the low-cost strategy, there are some disadvantages as well. One disadvantage is cutting prices too low and ending up with lower profitability. A second pitfall or disadvantage of low-cost strategy is not emphasizing avenues of cost advantage that can be kept proprietary or that relegate rivals to play catch up. (Thompson, Strickland, Gamble, 2010) Another disadvantage is the technological changes which can result in cost or process breakthroughs that nullify pas investments and efficiency gains. Generic Business Strategies, 2010) Strategic success in trying to be a low-cost firm usually requires a company to be the overall cost leader, not just one of the several firms trying for the position. When there is more than one aspiring low-cost firm, rivalry among them is typically fierce. (Generic Business Strategies, 2010) Southwest Airlines, Wal-Mart and Nucor Corporation are some companies who use the low-cost strategy. Here are some of Southwest’s key characteristics of its low-cost strategy: †¢Mastery of fst turnarounds at gates (25 minutes vs.  45 minutes for rivals) which allows planses to fly more hours per day, more flights to be scheduled per day with fewer aircraft and more revenue generated per plane on average than rivals; †¢Elimination of several services including in-flight meals, assigned seating and baggage transfer to connecting airlines results in costs savings; and †¢Fast, user-friendly online reservation system by facilitating e-ticket ing and reducing staffing requirements at telephone reservation centers and airport counters. (Kuzmicki, 2009) Another generic competitive strategy is broad differentiation strategies. According to Thompson, Strickland, and Gamble, in â€Å"Crafting and Executing Strategy†, broad differentiation strategy is seeking to differentiate the company’s product offering from rivals in ways that will appear to a brad spectrum of buyers. A company attempting to succeed through differentiation must study buyers’ needs and behavior carefully to learn what buyers consider important, what they think has value, and what they are willing to pay for. Then the company has to incorporate buyer-desired attributes into its product or service offering that will clearly set it apart from rivals. (Thompson, Strickland, Gamble, 2010) â€Å"Differentiation strategy is most likely to produce an attractive and lasting competitive edge when it is based on technical superiority, quality, giving customers more support services, and the appeal of more value for the money. † (Generic Business Strategies, 2010) Differentiation strategies work best in cases when there are various ways to differentiate the product or service and these differences are perceived by some buyers to have value; customers’ needs and uses of the item are diverse; and not many competitors’ firms are following a differentiation strategy. (Generic Business Strategies, 2010) Differentiations strategy has some advantages and disadvantages. Some advantages include the ability to have insulation against the strategies of rivals because customers establish a preference or loyalty for the brand or model; to erect entry barriers in the form of customer loyalty and uniqueness for new comers to hurdle; to mitigate the bargaining power of large buyers since the products of alternative sellers are less attractive to them; and put a firm in a better position to ward off threats from substitutes to the extent that it has built a loyal clientele. (Generic Business Strategies, 2010) Some pitfalls of the differentiation strategy include rapid imitations because competitors often reestablish similarity; buyers can see little value in the unique attributes of a company’s product; overspending on efforts to differentiate the company’s product offering which causes low profitability; over differentiating so that product quality or service levels exceed buyers’ needs; trying to a high price premium; and being timid and not striving to open up meaningful gaps in quality, service or performance. (Thompson, Strickland, Gamble, 2010) Many of companies use differentiation strategies which enhances profitability whenever the extra price the product commands out weighs the added costs of achieving the differentiation. Companies can practice differentiation from many angles. Microsoft Vista and Office and iPhone use multiple features to differentiate. Karastan in carpets, Michelin in tires, and Toyota and Honda in cars use quality manufacture as an angle. (Thompson, Strickland, Gamble, 2010) Best-cost provider strategies are another generic competitive strategy. These strategies aim at providing more value for the money. â€Å"A company achieves best-cost status from an ability to incorporate attractive or upscale attributes at a lower cost than rivals. † (Thompson, Strickland, Gamble, 2010) These attributes can be appealing features, excellent product performance or quality, or attractive customer service. The best-cost provider strategies work best in markets where buyer diversity makes product differentiation the norm and where many consumers are sensitive to price and value. This concept is true because a firm using the best-cost strategies can position itself in the middle of the market with either a medium quality product at a below average price or a high quality product at an average or slightly higher price. There is one big disadvantage to the best-cost provider strategies. It is getting in the middle of the strategies of firms using low-cost and high-end differentiation strategies. Customers might be driven to the low-cost providers by the appeal of the lower price despite the less appealing  product attributes. Also, the some customers might be attracted to the high-end differentiators with the appeal of better product attributes even though their products carry a higher price tag. Therefore, a company using the best-cost provider strategies must offer customers better product attributes in order to justify a price above what low-cost leaders are charging and it has to achieve lower costs in providing top notch features so that it can beat out high-end differentiators on the basis of significantly lower prices. (Thompson, Strickland, Gamble, 2010) As discussed in our textbook, â€Å"Crafting and Executing Strategy†, by Thompson, Strickland, Gamble, Toyota used the best-cost provider strategy for its Lexus division. Here are some of the key characteristics of the strategy. One characteristic was to design an array of high-performance elements and upscale features into Lexus models to make them comparable in performance /luxury to other high-end model, i. e. Mercedes, BMW. Another characteristic was to transfer its capabilities in making high-quality Toyota models at low cost to making premium-quality Lexus models at costs below other luxury car makers. Toyota used its relatively lower manufacturing costs to underpriced comparable Mercedes and BMW models. Another characteristic was to establish a new network of Lexus dealers, separate from Toyota dealers, dedicated to providing a level of personalized customer service unmatched in the industry. Thompson, Strickland, Gamble, 2010) The other two generic competitive strategies are the focused (market niche) strategies. These two strategies are the focused low-cost strategy and the focused differentiation strategy. The distinguishing feature of a focus strategy is that the firm specializes in serving only a portion of the total market. The underlying premise is that a firm can serve its narrow target market more effectively or more efficiently tan rivals that position themselves broadly. The competitive advantage of a focus strategy is earned either by differentiation, achieving lower costs in serving the target market, or both. (Generic Business Strategies, 2010) A focused strategy based on low cost aims at securing a competitive advantage by serving consumers in the target market niche at a lower costs and a lower price than rival competitors. Focused low-cost strategies are fairly common. According to Thompson, Strickland, Gamble, in â€Å"Crafting and Executing Strategy†, The Perrigo Company has become a leading manufacturer of over-the-counter health care products, with 2007 sales of more than $1. 4 billion, by focusing on producing private-label brands for retailers such as Wal-Mart, CVS, Walgreens, Rite-AID, and Safeway. Also, Motel 6 has used a low-cost strategy in catering to budget-conscious travelers who just want to pay for a clean, no-frills place to spend the night. (Thompson, Strickland, Gamble, 2010) According to Thompson, Strickland, Gamble, in â€Å"Crafting and Executing Strategy†, A focused strategy based on differentiation aims at securing a competitive advantage with a product offering carefully designed to appeal to the unique preferences and needs of a narrow, well-defined group of buyers (as distinguished from a broad differentiation strategy aimed at many buyer groups and market segments). Companies like Godiva Chocolates, Chanel, Gucci, Rolls-Royce, employ successful differentiation-based focused strategies targeted at upscale buyers wanted products and services with world-class attributes. (Thompson, Strickland, Gamble, 2010) The focused strategies work best with certain favorable market conditions. One favorable market condition is having a target market niche that is large enough to be profitable and offers a good growth potential. Another market condition is firms not seeing a presence in the niche as crucial to their success. If it is costly or difficult for multi-segment competitors to put capabilities in place to meet the specialized need of buyers which will comprise the target market niche and satisfy the expectations of their mainstream customers at the same time. Another condition is if the industry has many different niches and segments which allow a focuser to pick a competitively attractive niche suited to its resource strengths and capabilities. Also, if other competitors are attempting to specialize in the same target causing a condition that reduces the risk of segment overcrowding. (Thompson, Strickland, Gamble, 2010) There are a few risk associated with using the focus strategies. One risk is the possibility that broad-range competitors will find effective ways to match the focused firm in serving the narrow target market. Another risk is shifts in buyer preferences and needs away from the firm’s special product attributes toward more generally available features desired by the target segment. Also, the chance that competitors will find smaller segments within the target segment and â€Å"out focus† the firm. (Generic Business Strategies, 2010) Michael Porter said, â€Å"Competitive strategy is about being different. It means deliberately choosing to perform activities differently or to perform different activities than rivals to deliver a unique mix of value. † (Kuzmicki, 2009) Companies should choose from five generic business strategies when trying to successfully compete within their industries. As discussed above, the generic business strategies are the low-cost provider strategy, the broad differentiation strategy, the best-cost provider strategy; the focused strategy based on low costs, and the focused strategy based on differentiation. There are many benefits and risks to using these strategies. Also, companies have to be very careful in choosing the right strategy or strategies to pursue because the choosing the right generic strategy will affect several aspects of how the business will operate and the manner in which value chain activities must be managed. This decision is the most important decision a company will make because of its huge impact on the business. Firms can also choose to combine or switch between strategies. They must find the best strategy for the company without getting torn between the pros and cons of the various strategies and opt for â€Å"stuck-in-the-middle strategies†. These strategies rarely produce sustainable competitive advantage. If a company makes a vital commitment to one of the five generic competitive strategies, it will stand a chance of succeeding and sustaining competitive advantage. (Thompson, Strickland, Gamble, 2010) â€Å"Winners in business play rough and don’t apologize for it. The nicest part of playing hardball is watching your competitors squirm,† said George Stalk Jr. and Rob Lachenauer. (Kuzmicki, 2009) References

The Desert Ecosystems Complex Interrelationships

An ecosystem refers to different sets of interrelationships among living organisms, human beings and to the way they interact with their environment. The paper will focus on complex interrelationships of a desert ecosystem. Deserts are located near two tropics: the Tropics of Cancer and Capricorn; these two latitudes describe the zones where the sun is about ninety percent at noon.Advertising We will write a custom essay sample on The Desert Ecosystem’s Complex Interrelationships specifically for you for only $16.05 $11/page Learn More Deserts are divided into categories some of which include hot and cold deserts but they tend to have similar characteristics. An example of a cold desert is the Antarctica desert that is among the world’s largest deserts (Tewari, 1994). A desert’s is divided into abiotic and biotic components by structure; this in lay terms refers to non-living and living components of the ecosystem. Some of the abioti c components include soil. The main type of soil found in the desert is sandy soil characterized by alkaline PH, such soils have fewer organic matter and low water holding capacity hence referred to as poor soils. Water is another abiotic component whereby deserts are characterized by little or no water. Temperature as an abiotic component tends to be high during the day and relatively low at night. Wind and climate are also abiotic components. Biotic components of a desert ecosystem consist of plants and animals, whereby these organisms have the ability to sustain extreme temperatures. They also tend to have low production levels and lack diversity because of nutrient inadequacy in this ecosystem. Desert functionality calls for different cycles, for example, the carbon cycle takes a continuous form. The cycle capitalizes on activities of biotic components, as plants take carbon dioxide, water and light in the process of trying to make food and compounds full of carbon. When these p lants wither or die, they rot hence giving back carbon elements that had been taken from the soil earlier. Later on young sprouting plants take in these elements. Animals play a vital role in ensuring the success of the carbon cycle, during respiration they do breathe in oxygen and give out carbon dioxide. When these animals die, they decompose giving back nutrients to the soil, and this ensures continuity of the cycle. Another cycle in the desert ecosystem is the nitrogen cycle; it refers to how nitrogen is consumed and replaced back to the ecosystem. In a desert ecosystem, the cycle begins with desert plants taking up nitrogen, animals then consume these plants rich in nitrogen as food, the animals are consumed by other animals (carnivores).When this happens nitrogen that was taken from the plants is transferred to the carnivores. In case of death or excretion their remains decompose giving back nitrogen to the soil, soil organisms then assimilate it making it available for the us e by plants.Advertising Looking for essay on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More Functionality of the desert ecosystem is normally disturbed by certain causes some of which include natural causes. Such natural occurrences as earthquakes, earth tremors and landslides may lead to alteration of the normal functionality of the ecosystem. This may lead to the destruction of the soil structure and general structure of the desert. It may also interfere with the land and the normal systems like gaseous exchange and production levels in the desert. Anthropogenic disturbances may also interfere with the desert ecosystem; some of these include mining activities, infrastructure development activities, air pollution, overgrazing and military training activities. High occurrence of these anthropogenic activities leads to the destruction of vegetation in the desert, unstable soils in terms of structure and increased soil e rosion. Ecosystems recover from initial disturbances through resilience and the theory of secondary succession. Resilience refers to the ability of an environment to maintain its original state, activities and functions despite stress. It is a combination of methods helping to increase the system’s productivity by providing the resources for higher production. Maintenance of local characteristics of the ecosystem helps it to recover; these characteristics will help decrease soil erosion, maintain soil structure and increase diversity. Secondary succession theory can also facilitate this recovery strategy using the above quoted methods. Reference Tewari, D. N. (1994). Desert ecosystem.

Plants essays

Plants essays Fertilizer has played an important role in the health and growth of plants since the beginning of time. Fertilizer has helped farmers and million of people across the world to grow healthy plants that they could sell to the public. It does not have to be sold in bags to be considered fertilizer. Even a banana peal is fertilizer because it promotes the growth and helps improve the health of the plant. For plants to have a successful life they need to be supplied with various types and amounts of nutrients which is sufficiently provided by fertilizers (Secrets to great soil, 1998). There are two types on nutrients that are absorbed and used by plants(Improving the soil, 1996). Those two are macronutrients and micronutrients(Improving the soil, 1996). Micronutrients are the types of nutrients that are used less by plants because they are not as essential for good health(Improving the soil, 1996). They help the plant grow healthy, but the plant can live without them. Some types of micronutrients include calcium, magnesium, sulfur, boron, and manganese (Easy Compost,1997). Plants use macronutrients more frequently than micronutrients (Espoma, 2002). They are necessary and much more essential for the growth of plants than micronutrients (Espoma, 2002).. Macronutrients unlike micronutrients are extremely important for the plants life(Improving the soil, 1996). Without them a plant would most certainly die (Espoma, 2002). . These nutrients are in high demand. They are nitrogen, phosphorus, and potassium(Improving the soil, 1996). Phosphorus is one of the most vital nutrients that a plant needs(Secrets to great soil, 1998). It has a great amount of important role that it fulfills that helps maintain the plants health. One essential role that phosphorus plays in the development of plants is the improvement of its immune system(Secrets to great soil, 1998).. Just like humans, plants can also get ill. That is just one of the many...

Christianity and the World of Faith Essay Example | Topics and Well Written Essays - 500 words

Christianity and the World of Faith - Essay Example Same is the case with love and tolerance which needs to be set in free so that people can understand how it is essential to inculcate a society which bases itself on growth and productivity of its own people. If they interact freely, it is taken as a plus point, and even Christianity accepts it with both arms wide open. Similarly, making education and healthcare free throughout the world will help the cause of any society of the world and hence help us get across the dictum of difficulties that have more bearing on the lives of the people that are seen possible (Rolfe, 2004). I opine that Christianity allows people to live freely and understand the real value of love, tolerance, compassion, and empathy. Christianity helps the people to evolve in a positive fashion which indeed is a good thing. Hence I see these three issues currently being signed for the different societies that exist within the world in the present times. My own core beliefs regarding Christianity surround the basis of doing well on to others so that it comes back in some form. Also, believe in God that he knows about everything and that Jesus was the noblest of men amongst all mankind. I base my beliefs on Christianity with what I have learned over the years as well as what my elders have told me over the years. I have seen devoted Christians during my lifetime who have always believed the basis of their religion because they tend to feel it this way. I am confident that Christians all over the world are proactively driven to bring goodness forward and this is one aspect that has been documented time and again (Emmett, 2011). From my perspective, Christianity is very close to being good to one’s own self as well as to the people who come in contact with this individual. I feel confident about Christianity because it provides peace of mind and heart.

If such a scenario occurs, the students will therefore quit to be in that environment and look for a better place off campus where needs would be catered for. Westminster business school students have been raising opinions on the students living halls and comparing it to the private accommodation in central London. Tabling some of the opinions, advantages and disadvantages of the two students residing places came up in conjunction to the timing references and motivation factors. Therefore, in order to analyze their opinions they give on the advantages of living in both private and campus halls they came up with these: The students also enjoy the school facilities and are in an environment suitable for their studies with fewer distractions ("Why live in the residence halls? :: Residence Life and Student Housing | The University of New Mexico," n.d.). However, despite of the gainful advantages that the students encounter in these premises, there are also disadvantages that come along with them. For this instance, comparison of both private and university halls opinions give in to the presentation. In private apartments, not all are students and so it comes with greater responsibility of taking of one’s duties and bills and considering other people in the same place thus, lots of noise is minimal and other quire college behavior. In this instance, the private hall students are able to take responsibility at their own, which reflects in their future unlike students in university halls. Most of private apartments are costly hence students may share the rooms which comes with a sober decision making of who your friends are, and again these private goes all year round that means during summer break the student will need to pay for them. Transportation is also a student’s responsibility especially where it is not available it may get to some

Essay on Light and Dark in Antigone -- Antigone essays

Use of Light and Dark in Antigone    The "Golden Age" of Greece is noted for its many contributions to the creative world, especially in its development of the play. These performances strived to emphasize Greek morals, and were produced principally for this purpose. Antigone, by Sophocles, is typical. The moral focused on in Antigone is the conflict between physis (nature) and nomos (law), with physis ultimately presiding over nomos. Throughout Antigone, King Creon is a symbol for nomos, while Antigone stands on the side of physis. To portray these ideas, light and dark images are used as a recurring motif to reinforce the theme. Light is used to show something good that is happening, whereas dark is utilized to show something of which the gods disapprove. Following with tradition, this play uses light to portray what is right in the eyes of the chorus and darkness to reproach the other side. As the play is carried out, the chorus is constantly changing its opinions, first believing in the actions of Creon with respect to nomos, then unsure of what to believe, and finally seeing that Antigone's actions are more consistent with the morality of the gods and the truths of physis. Light and darkness are used to support in an emotional way the action of whoever the chorus is siding with at these various stages of the play. It is clear that at the beginning of Antigone, the chorus favors the actions of Creon, or nomos. This is shown as Creon's intentions and retribution towards Polyneices are justified by jovial words and imagery involving light. In the battle between Eteocles and Polyneices, although both leaders were killed, Eteocles' army was the victor. To show that this was positive in the eyes of the gods, the first lin... ... with connection to nomos was too high, and images referring to him are now dark and dismal. The play ends as the gods have turned their shoulder on Creon, and have made their final decision that Antigone is ultimately in the right. Because the sole purpose of Antigone is to get a moral point across, the parallels between light and dark and physis and nomos are associated together, and used metaphorically to add diversity and imagery to an otherwise redundant script. In the first scenes, these light and dark images show the reign of Creon. These are followed by the indistinct and ironic middle scenes, and end with the gods choosing Antigone's actions over Creon's, leaving Creon spiritually dead and paying for his poor choices and conduct. These are very effective techniques, which allow Sophocles to more fully develop his play, and give it a more emotional edge.

These traits are the personification of what society has indicated to be the perfect man; or, depending on which superhero, a woman.Many superhero fans begin as children and often remain intrigued into adulthood; from wearing their uniform, to owning every one of their movies, to becoming a superhero, themselves. However, becoming a superhero is an obvious impossibility. These supernatural beings have the ability to fly, master the intelligence of villains, lift the heaviest objects, and jump off the highest buildings with no harm being done. It is the ideals of becoming someone great, which superheroes portray, that influence children and enhance their yearning to imitate the superhero’s image and actions.A superhero’s immense strength, chiseled toned body, and sharp intelligence are a few attributes that provoke fans to admire and idolize these beings. Many parents believe that children’s aggressive behavior is uncontrollable but it is also a result from the vigorously powerful superheroes that act as role models to children as they are growing up. Superheroes incredible strength has led them to victory over the biggest and strongest of enemies.I interviewed my acquaintance, Jon Wall, a senior at McNeese State University, who has an admiration for Superman, and he said, â€Å"From watching Superman, I thought I could prove my strength by defeating other kids. This did not mean that I went and tried to beat everyone up. Instead, I tried to be better than others at everything. I would try to hang on the monkey bars the longest, be the person who got picked first for any sport, and wrestle anyone to submission. † he continued, â€Å"Although my behavior sometimes got too aggressive, and got me in trouble, it always seemed to make me feel like more of man. Jon’s explanation is one of many children who have set their standard of being a real man or woman based on the strength and accomplishments of a superhero. Achieving victories that a superhero has demonstrated has caused many fans to feel as an accomplished being, finally worthy to be called a real woman or man. Superheroe s also tend to possess a perfect physique that enhances their powerful ability to conquer and defeat evil. They always have a defined figure, toned muscle in every area, and, usually, six-pack abs. Although physical image is more of an interest with teenagers and adults, this does have an effect on children, too.These role models that children are introduced to hold a nearly impossible figure for all children to achieve. It is from these images that communicate to kids that being overweight and lacking strength is unacceptable. This aspect is a contribution to children mistreating other children who do not hold to this idolized standard. My friend Jon stated, â€Å"I fell into the trap of mocking others, who were not perfect, when I was a kid. I also remember trying to hide any blemish of my own body, so that I would not become a victim of the scorn [from other children]†.Jon’s experience of feeling pressure to maintain a certain physical image exemplifies the cases of many superhero fans. Children are feeling pressure to portray a certain image in order to achieve self-security and acceptance from others instead of having a healthy mentality regarding food and exercise. Aside from all physical traits of a superhero, they also portray a strong sense of intelligence. It requires mass strategy and mental knowledge to defeat evil villains and their deceptive ways. Superheroes encounter many difficult and seemingly impossible challenges and manage to take them head on without any evidence of fear.Breann, a classmate in my English 101 class, stated, â€Å"I think that the intelligence of a superhero is extremely influential because they are faced against evil villains, who are known for their intelligence and strategic ways, and superheroes always end up defeating them† she continued, â€Å"When children see the knowledge of a superhero portrayed in their planning of defeat against their enemies and them achieve victory, it is a positive influ ence for the children to try their hardest in school to gain an education to be able to plan, have broad knowledge, and defeat, as well. Intelligence holds a large role in the world and one’s likelihood of reaching success. Intelligence is a positive attribute that superheroes portray when their knowledge and skill is shown through their preparation and process of defeating evil. A characteristic of all superheroes is their great achievement. Superheroes are constantly saving the world and others from harm.They have great impacts on the way most children that admired them grew up. Whether it was Batman, Wonder Woman, or some other supernatural being, they all had a lot to say about what it means to be a man or woman. Even if the ideals portrayed are imaginative beings, a superheroes image has the ability to influence any child. Works Cited Wall, Jon. Personal interview. February 22, 2013. Debarge, Breann.

Investment and Market Risk Premium

Cost of Capital at Ameritrade Day 1 1. What factors should Ameritrade management consider when evaluating the proposed advertising program and technology upgrades? Why? -They should see how revenues have changed after adopting the new ad program and technology upgrades -They need to see ROI for their investments over time 2. How can the Capital Asset Pricing Model be used to estimate the cost of capital (required return) for calculating the net present value of a project's cash flows? it will help us determine the Cost of capital or discount rate which we can use to calculate NPV, in other terms the numerator will never change (FCF), only the denominator will based on the cost of capital3. What is the estimate of the risk-free rate that should be employed in calculating the cost of capiual for Ameritrade's proposed investment? – the risk free rate should be the T-bills rate or the average annualized total annual returns on US government securities = 3. %. In my opinion, we sho uld use the risk-free rate equal to yield of 20-year US government securities, because it is long-term capital investment. We may use 30-year rate, but we are investing in technology, and concerning the speed of technological enhancements, 20-year rate is optimal. So it is 6,69% 4. What is the estimate of the market risk premium that should be employed in calculating the cost of capital for Ameritrade's proposed investment? Market Risk PremiumThree distinct concepts are part of market risk premium: 1) Required market risk premium: the return of a portfolio over the risk-free rate (such as that of treasury bonds ) required by an investor; 2) Historical market risk premium: the historical differential return of the market over treasury bonds; and 3) Expected market risk premium: the expected differential return of the market over treasury bonds. Also called equity premium, market premium and risk premium.Market Risk Premium = Expected Return of the Market – Risk-Free Rate The e xpected return of the market can be based on the S;P 500, for example, while the risk-free rate is often based on the current returns of treasury bonds. First to find the Expected Return of the market, from Exhibit 6, We take the aggregate stock market and multiply by 12: = 15. 71% The Risk-free rate is 3. 8% =;gt; The market risk premium= 15. 7 – 3. 8 = 11. 9% (That is why we may use the difference between US Government Securities rate (6,69%)and historical Large Company Stocks annual returns.But we have 2 numbers: during1950-96 and 1929-96. The difference between them is 1,3%. I think that we should useâ€Å" younger† value of 14%, because the years 1930-1949, of course, were under market economy, but at the same time there were not so stable laws, a Second World War passed, many companies at that time worked for government orders, so this number may be a bit out of overall tendencies. ) 5. In principle, how would one go about determining beta for purposes of calcula ting the cost of capital for Ameritrade's proposed investment?TO calculate Beta for cost of capital, or asset beta: We need to find first the Equity Beta = by regressing stock returns over market returns and it will then be the slope. We also need to calculate the market value of the equity of the firm which is the price per share multiplied by the total number of shares outstanding (see attached notes) A cost of capital is a weighted average of the cost of debt and equity. Likewise, the asset beta is the weighted average betas of debt and equity. We use market value proportions of debt and equity (see CAPM, p. 476). Ba = (D/D+E)BetaD+ (E/D+E)BetaEIt is common to assume that debt has no relationship to market risk; that BetaD=0 Empirical studies of corporate debt returns suggest it would be better to assign some market-related risk to corporate debt; and use estimates ranging from 0. 20 to 0. 30. To get BetaE, the equity beta for Ameritrade, we would normally run a regression of equ ity returns on stock market returns. That is, we would estimate the slope of the line that best fits: Unfortunately, Ameritrade had their IPO (Initial Purchase Offer) in March of 1997, so there is not enough data at the time of the case to calculate a reliable beta estimate.So instead, we will look at comparable firms. Firms in the same industry pursuing the same types of projects will have the same sorts of risks, thus their asset betas will be approximately the same. The returns we calculate for these firms, based on stock price movement, dividends, and stock splits, are their equity betas. These are influenced by the degree of leverage each company is using (recall that higher leverage leads to higher ROE, EPS and DPS, but also leads to greater variability in earnings).Knowing the amount of debt in their capital structures (at market values), we can calculate the asset beta for each comparable firm. Then we will average these to use as a proxy for Ameritrade’s asset beta N ote: An agent that mediates sales and exchanges between securities buyers and sellers at even lower commission rates than those offered by a regular discount broker . As one might expect, deep discount brokers also provide fewer services to clients than standard brokers; such brokers typically provide little more than the fulfillment of stock and option trades, charging a flat fee for each.The problem that must be overcome in determining the implementation decision is the uncertainty of the cost of capital. Other Methods of Estimating Cost of Equity Capital: †¢The EP Method r = EPS / Stock Price †¢The Constant Growth (Gordon) Model r = DIV1 / P 0 + g compute g from earnings, dividend, or cash flow growth or use the sustainable growth estimate ? Equity Betas, the relationship of a given equity’s risk to that of the larger market, reflects two kinds of risk –The risk of the business itself –The risk that the debt a business has will prevent cash flow to equity ?We can de-lever these equity betas to strip out financial risk associated with leverage and find the implied beta for the business itself (asset beta) –Asset beta measures the business risk only and does not change with capital structure ? Often, the best way to estimate a forward looking asset beta for a company is to take a median of its industry peers asset betas (historically calculated) since one-time company events in the past will be averaged out ? We can then find the equity beta for the company by re-levering the industry asset beta to the target debt / cap ratio of the company ?Exhibit 4 provides various choices of comparable firms. Which firms do you recommend as the appropriate benchmarks for evaluating the risk of Ameritrade’s planned advertising and technology investments? Determine the betas for these firms. Let us agree that Charles Schwab is a comparable firm. Their price changes, dividends,and stock split information for 1992-1996 is in Exhibi t 5. If there were no stock split, thereturn, compared to the previous period, is given by: For example, if the price the previous period was $100, then wentup to $104, and in addition had a dividend of $8, the return would be +0. 12, or 12%.In ashort time period, the returns will be much closer to 0. If there is an X for y stock split, use the formula: Copy the Return values into Exhibit 6 alongside the appropriate dates, then regress theSchwab returns against the value-weighted NYSE returns for the same period. The slopeof the line is the equity beta. Do this for the other comparable firms. Calculate the asset betas using the formula inquestion 5 (twice, once with Beta D = 0 and once with 25. 0). Average the results. This should be a good estimate of Ameritrade’s asset beta. Finally, put these results back into the equation in #2 to estimate Ameritrade’s cost of capital

What to do when your boss is stealing your ideas

What to do when your boss is stealing your ideas There are lots of potentially difficult situations that arise in most workplaces- anything from annoying coworkers, to incompetent people on a project team, to having to work twice as hard in an effort to pick up the slack for a lazy, underperforming colleague who always seems to wiggle out of trouble. But the truth is, one of the most challenging professional situations to have to deal with is a scheming and self-serving boss who is constantly stealing your ideas or taking credit for your work, leaving you in the dust with nothing to show for your efforts and accomplishments. Hopefully this doesn’t sound familiar or hit too close to home for you- but if it does, we know how difficult it can be. The last thing any of us want to do is put ourselves into an adversarial situation with our bosses, so there’s a real impulse not to say or do anything about it- which can quietly â€Å"signal† your boss that you’re okay with their bad behavior or at the very least not going to rock the boat for them, which means the theft may continue (or get worse).It’s important to do  something  when your boss is stealing your ideas. But how can you handle the situation delicately enough so that you don’t make things unbearable for yourself, yet firmly and decisively enough to send a clear message that you’re not willing to put up with this?If you or someone you know is struggling with this reality, there is hope, and a way forward. Entrepreneur published an article  that highlights strategies for dealing with a boss who takes credit for your ideas. Use the following to help guide you through the potential hazards and pitfalls of the tough spot you’re in and hopefully make it through unscathed.Step 1: Evaluate the situationWhen you first start getting the feeling that your boss is taking credit for your ideas, your first step is not to unleash the fury on the powers that be in an effort at vengeance or retribution. Take a step back to get some valuable perspective and evaluate the situation. Is your boss really stealing your ideas or just aggregating and presenting the work for the team that reports to her or him? Are you absolutely certain that you’re not getting credit for your work? Just because you may not receive instant adulation for your ideas does not mean that your efforts are going unnoticed. Perhaps your boss is not the overly effusive sort, but nonetheless is appreciative of your contributions and is giving credit where it’s due in a subtle way, or is simply waiting for your next review period to give you your well-deserved rewards? Bottom line- make sure you know for sure that your boss is stealing your ideas before taking things any further.Step 2: Get a second opinion/witness.Okay, so you’re fairly certain that your boss is indeed taking credit for your work- what should you do next? The next best step is to get a second opinion in an effort to have a witness to t he situation in your corner. Why is this so important? Because without a witness, unless you have absolutely irrefutable evidence it’s basically your word vs. your boss’s, and in this scenario the boss often wins. Don’t put yourself in that scenario- instead, choose a credible and reliable witness, preferably someone with a little clout at your workplace, and help your case by having that person in your corner. It could make all the difference if you decide to take things further.Step 3: Document your case.A strong, impassioned story and credible witness will go a long way towards supporting your claim of idea theft, but nothing beats a solid â€Å"paper trail.† Wherever feasible, have some ironclad evidence that documents the onerous events- everything from emails to recorded instances of theft and proof that the ideas were indeed yours to begin with will all serve to substantiate your claim. Nothing is more disheartening than making a bold claim of thef t that you’re unable to prove and it ultimately goes nowhere. Not only will your work situation not improve, it will likely become even more uncomfortable for you there.Step 4: Communicate with your boss.No, we’re not suggesting you kick open their office door and yell at them at the top of your lungs in an effort to get them to admit their wrongdoing. Instead, we’re saying that there may be a more peaceful and professional way to reach a satisfying conclusion. If you politely discuss the situation with your boss, they may be able to capably explain why you’re mistaken about what has transpired. Or maybe they’ll realize they’ve failed to properly give you the credit you’re due are willing to make amends. Often, the path of least resistance is the best one to take first. Hopefully your boss is reasonable enough to deal with, provided your approach is free from hostility and you’re open to reasonable and equitable compromise.If y ou think your boss might be profiting from your ideas without sharing the credit, don’t just do nothing- but don’t do anything rash, either. Take a breath, assess the situation, and make your way through the measured and professional steps mentioned here to come to a resolution that gives you the credit you deserve.

How Weather Affects Fall Colors

How Weather Affects Fall Colors Nothing says autumn quite like a lazy drive through the countryside with the sun illuminating oranges, reds, and yellows in the treetops. But before planning a day of leaf-peeping, its a good idea to check local and regional weather forecasts- and not simply for travel weather purposes. Weather conditions such as temperature, precipitation, and amount of sunlight, actually determine how vibrant (or not) fall colors will be. Leaf Pigment Leaves have a functional purpose for trees: They produce energy for the entire plant. Their broad shape makes them good for capturing sunlight. Once absorbed, the sunlight interacts with carbon dioxide and water within the leaf to produce sugars and oxygen in a process known as photosynthesis. The plant molecule responsible for this process is called chlorophyll. Chlorophyll is responsible for giving a leaf its trademark green color. But chlorophyll isnt the only pigment residing within leaves. Yellow and orange pigments (xanthophylls and carotenoids) are also present; these remain hidden for most of the year because chlorophyll masks them. Chlorophyll is continually depleted by sunlight and is replenished by the leaf through the growing season. Only when chlorophyll levels subside do the other pigments  become visible. Why Leaves Change Color While a number of factors (including weather) influence the brilliance of leaf color, only one event is responsible for  triggering  the decline of chlorophyll:  the shorter daylight and longer overnight hours associated with the change in season from summer to fall. Plants depend on light for energy, but the amount they get changes through the seasons. Beginning on the summer solstice, Earths daylight hours gradually decrease and its nighttime hours gradually increase. This trend continues until the shortest day and longest night is reached on December 21 or 22 each year (the winter solstice). As the nights progressively lengthen and cool, a trees cells begin the process of sealing off its leaves in preparation for winter. During winter, temperatures are too cold, sunlight too dim, and water too scarce and susceptible to freezing to support growth. A corky barrier is formed between each branch and each leaf stem. This cellular membrane blocks the flow of nutrients into the leaf, which also stops the leaf from making new chlorophyll. Chlorophyll production slows and eventually stops. The old chlorophyll begins to decompose, and when its all gone, the leafs green color lifts. In the absence of chlorophyll, the leafs yellow and orange hues dominate. As sugars become trapped inside the leaf by the trees sealant, red and purple (anthocyanins) pigments are also created. Whether by decomposition or by freezing, all of these pigments eventually break down. After this happens, only browns (tannins) are left. Effects of Weather According to the U.S.  National Arboretum, heres how the following weather conditions at each stage of the leaf growing season work to the benefit or detriment of  foliage come September, October, and November: During spring, a wet growing season is ideal.  Drought conditions during the spring (the beginning of the leaf growing season)  can cause the sealing barrier between leaf stem and tree branch to form earlier than normal. This, in turn, can lead to an early shutdown of leaves: Theyll drop before theyve had a chance to develop fall coloration.From summer into early autumn, sunny days and cool nights are desirable.  While adequate moisture is good during the early growing season, it works to mute colors in the early fall. Cool temperatures and abundant sunshine cause chlorophyll to be destroyed more rapidly (recall that chlorophyll breaks down with exposure to light), thus allowing yellows and oranges to be revealed sooner, and also promoting the formation of more anthocyanins.  While cool is best, too cold is detrimental. Freezing temperatures and frosts can kill thin and fragile leaves.During autumn, calm days prolong viewing opportunities.  Once the autumn season arrives, l eaves need time for the buildup of chlorophyll to entirely fade and their dormant pigments to fully take over. Gusty winds and hard rains can cause leaves to fall before their full color potential is reached. The conditions that make for spectacular autumn color displays are a moist growing season followed by a dry autumn with warm, sunny days and cool (but not freezing) nights.

Data analysis - Speech or Presentation Example Teachers report using many of the reform strands almost every day or several times a week. The reforms most used (by at least 70% of the teachers) were constructivism, learning styles, thematic approach, alternative assessment, equity, STS, technology, and science subject matter. Alternative assessment (90%), equity (88%), and technology (83%) were the most used reform strands the teachers reporting using it â€Å"almost every day† or â€Å"several times a week†. Classroom management stood out among the reform strands least implemented in the classroom. Only 45% of teachers reported using classroom management almost every day or several times a week. Less frequently used reform strands (used once a week, less than once a week, or never) by over 30% of teachers include classroom management (55%), cooperative learning (42%), hands-on/minds-on activities (37%), and nature of science (30%). Considering all items measuring the necessity of the reforms to be an effective science teacher are equal, a new variable â€Å"belief† was formed. Similarly, a new variable â€Å"implementation† was formed by adding all items in implementation of the reform in teacher
