Analytical Essay Sample on the Impact of Human Activities on Natural Hazards

Analytical Essay Sample on the Impact of Human Activities on Natural Hazards Natural hazards are naturally occurring phenomena that have disastrous impact on humanity. These phenomena had been in existence even before the advent of humanity. The hazardous dimension of these natural phenomena are in the context of the impact that such a phenomenon would have on human population in the area affected by that phenomenon. In this essay, the effect that human activity has on these natural hazards would be analyzed. Some human activities may be exacerbating the factors that cause the natural hazard, like the impact of excessive and unplanned logging on floods and droughts. In certain other cases the human activities may cause subsequent or supplementary hazards to a primary hazard event, like building dams in earthquake prone zones may lead to flash floods and landslides in the event of a rupture. A hazard can be defined as an event that has the potential to cause harm. This potential may be on account of its unexpected timing of occurrence or the actual intensity of the event itself. Human societies can withstand these events within a normal scale of occurrence. However, human societies become vulnerable when these events occur unexpectedly or are of an intensity or duration that falls beyond that normal scale (O’Hare and Rivas, 2005). Natural hazards can be broadly classified under the heads of geological, hydrological, climatic and diseases. This essay would limit its scope to analyzing causal relationships, if any, of human activities on landslides, floods and drought and the secondary hazards triggered by those activities in the event of an earthquake. Of all human activities that have a direct or indirect impact on natural hazards, deforestation is by far the most significant. Deforestation is the removal or destruction of forest cover of an area. It may occur due to unscientific logging practices without regeneration and may be accompanied by subsequent conversion to non-forest usage like agriculture, pasture, urban, mining or industrial development, fallow or wetland. At a very broad level, it has been argued that deforestation is a major cause of global climatic changes. It has been predicted that removal of forest cover will lead to violent and unpredictable environmental fluctuations. At a smaller landscape, deforestation has a direct bearing upon the climatic, hydrological, edaphic and biological aspects of that area. Deforestation is associated with higher levels of soil erosion and landslides, sedimentation in river beds and changes in fluvial geomorphology (Haigh, 1984). Quite a few of these effects of deforestation have a direct bearing on the natural hazards that will be covered in this essay. One of the major functions of a forest is to maintain the humidity level in the atmosphere. Trees withdraw groundwater through their roots and transpire the excess water through their leaves. Forests return a major part of the rainfall received by them through evapotranspiration. Annual evapotranspiration in tropical moist lowland forests ranges up to 1500 mm per year, with transpiration accounting for a maximum of 1045 mm per year (Bruijnzeel, 1990). This process of evapotranspiration in the leaves of trees takes the latent heat of evaporation from the surrounding atmosphere. Thus evapotranspiration has a cooling effect on the atmosphere that aids precipitation. Deforestation denies the atmosphere of this cooling effect and is thus a contributing factor to lowering of annual rainfall in an area. Further, the effects of deforestation generally compound the severity of drought. Lack of trees translates to the lack of root fibers that hold the topsoil. In the event of a drought, the topsoil flakes and gets blown by the wind, leading to severe dust storms. This phenomenon had devastated the American Great Plains for close to a decade in 1930s. The dust bowl covered farming areas in Colorado, Kansas, north west Oklahoma, north Texas and north east New Mexico. The fertile soil of the plains was exposed due to lack of vegetation cover and actions of the plow. These farming techniques that led to severe soil erosion, coupled with prolonged periods of extremely low rainfall, led to a series of severe dust storms that ranged up to the Atlantic coast. Much of the fertile topsoil was lost in the Atlantic (Cartensen et al., 1999). Direct causal relationship between human activity and drought is yet to be conclusively established. However, there are studies available that point to a positive correlation between the two. For example, climate-modeling studies have indicated that the 20th century Sahel drought was caused by changing sea surface temperatures. These changes were due to a combination of natural variability and human induced atmospheric changes. The anthropogenic factors in this case were rise in greenhouse gas levels and aerosols (GFDL Climate Modeling Research Highlights, 2007). The effect of human activities like deforestation is rather more direct and pronounced in case of hydrological hazards like fluvial floods. Fluvial floods occur when the discharge of a river exceeds its bankfull capacity. Forests create deep, open textured soils that can hold large quantities of water. When the forest cover is removed through logging, the soil becomes compacted. More rainwater is converted to runoff or near surface flow and less proportion percolates as groundwater. Research has shown significant increase in monthly runoff following logging activities (Rahim and Harding, 1993). The runoff rainwater carries with it considerable amounts of loose soil particles. Removal of vegetation cover through excessive logging activities or overgrazing leaves the soil bare. In such a situation, the upper layer of the soils becomes susceptible to erosion by surface runoff. These suspended soil particles are deposited on the riverbeds. The effect of this type of soil erosion by surface runoff is even more pronounced when the deforestation happens in the riparian zones as well. With time, this sedimentation decreases the depth of the riverbed and, thereby, the water carrying capacity of that river. When the flow of water in the river increases due to a variety of reasons like rainfall, seasonal melting of ice etc, that river can no longer contain the flow within its channel due to reduced drainage efficiency. This excess water inundates adjoining areas causing floods. The effect of soil erosion and subsequent sedimentation of the riverbeds enhances both the occurrences of floods and the area affected by floods. The impact of deforestation driven soil erosion is particularly severe in mountainous terrain. In the western Himalayas, comparison of bedload sediments trapped from parallel streams found that the sediment loads from undisturbed forest were five-seven times smaller than from deforested areas covered by grass and scrub. Deforested areas had a much smaller depth of soil and in many places large patches of underlying bedrock had become exposed ( Haigh et al., 1998). The result of this type of soil erosion on floods is amply demonstrated in the river systems in peninsular Malaysia. Malaysia is located in the equatorial belt and receives very heavy rainfall throughout the year. Peninsular Malaysia has a dense river network. The largest of around one hundred river systems is the Pahang. The runoff along exposed hillsides on the upper courses of the rivers lead to heavy soil erosion and major silting in the lower courses. Peninsular Malaysia has a major tin mining industry and disposal of unwanted tin mining tailings in watercourses has greatly accentuated the silting process. This has majorly worsened the flood situation, both in terms of inundation area and duration of flooding. The effect is particularly severe in Perak and Selangor (Chan and Parker, 1996). The type of natural hazard that is most closely linked to human activity is the landslide. A landslide can be defined as the movement of a mass of rock, soil or debris downward a slope. These occur on steep slopes of hilly terrains that demonstrate certain inherent factors like susceptible rock structure, weak material or slope form. The preparatory factors actively produce the changes that make slopes more vulnerable to a slide, without actually causing it. Some preparatory factor may ultimately become the triggering factor and start the landslide. In some other cases, geological or climatic events like earthquakes or rainstorms initiate the movement. Human activities cause some of the more widespread preparatory factors. Removal of forest cover from mountain slopes deprives the soil of the binding force of the roots of vegetation, thereby making it more vulnerable. Removal of the toe of the slope renders the mass above, unstable. This is because the lateral buttressing support for the bulk of the slope that lies on top of the excavated area is removed. Human activities like building of roads or quarrying of minerals are responsible for this type of preparatory factor. In many cases, human settlement on the slopes alters the original surface drainage of that area, eventually rendering it hydrologically unstable. The effects of human activity in the preparatory factors of a landslide were demonstrated in the landslide at Abbotsford, South Island, New Zealand on 8th August 1979. Deforestation, quarrying and modification of surface drainage further endangered the geologically unstable slope. Heavy rainfall and leakage from city water supply pipeline finally triggered the massive landslide (Pacione, 1999). Human activity like construction of roads can have a major impact on the vulnerability of a mountain slope. For example, the Indian Central Himalayas have seen major increase in road construction activities after the war with China in 1962. Many of these roads are poorly designed and constructed. This has dramatically increased in the occurrences of landslides in the region (Ives, 2004). Human intervention on the natural drainage of a slope as a major contributing factor to a landslide is amply demonstrated in the multiple occurrences of landslides on the hill slopes of La Paz city in Bolivia. La Paz region has considerable human settlements that are on unconsolidated slopes. These slopes are frequently wetted to saturation and forced to move. Some of these factors are natural, like seasonal convective showers of high intensity, flooding of lowers slopes by the rivers and streams draining that rainfall and water seepage from fluctuating water tables of adjoining lake Titicaca basin. However, the water saturation of the slopes is exacerbated by the human settlement on the slopes. Much of such settlements are unplanned, self-help housing that have no access to public sanitation and drainage systems. Waste water from such houses are drained directly on to the slopes. These factors have led to repeated landslides in the La Paz region in the past (O’Hare and Rivas, 2005). Another type of mass movement that is seen in plain areas is subsidence. Subsidence is vertical sinking of materials. In many unplanned cities, the city has sprawled into areas not covered by municipal water distribution network and indiscriminate ground water usage through bore wells have severely depleted water tables. In some cities like Mexico and Bangkok, the drained soil has compacted, leading to subsidence. In some other regions like the Raniganj – Jharia coal belt in India, improper mining excavations and inappropriate filling of excavated tunnels have led to widespread subsidence. In certain cases, though human activity does not cause a natural hazard, it may lead to secondary hazard events subsequent to the occurrence of a primary hazard. A case in point is the building of a very high multipurpose dam at Tehri in the Himalayan region in India that may be susceptible to seismic activity. In the eventuality of an earthquake and subsequent rupture of such a high dam, a tremendous flash flood is inevitable on the lower courses of the river, accompanied by major landslides as well (Ives, 2004). Thus, it can be concluded that human activities have some impact on occurrence of natural hazards. For some hazards like landslides and subsidence, there is direct, causal relationship between human activity and hazard occurrence. In some other cases like drought and floods, unscientific and unplanned exploitation of natural resources exacerbate natural hazards. In yet other cases, human activity compounds the effect of a natural hazard by triggering other hazard events that follow.

Most Common Answer on the ACT Guess C

Most Common Answer on the ACT Guess C SAT / ACT Prep Online Guides and Tips Everyone knows that, when guessing on a multiple-choice test, the best answer to choose is C...right? A friend of a friend swears by it, it’s served you well in the past (maybe?), and it’s become such a commonly known â€Å"fact,† such an undisputed strategy, that you may feel as if you were born knowing it- †when in doubt, pick C and move on.† But does this time-honored tradition of picking C when in doubt actually work on the ACT? And if not, what can you do to improve your odds when guessing? Let’s look at the facts. Why You Should Answer Every Question on the ACT First of all, there is no penalty for choosing a wrong answer on the ACT, so make sure tonever leave a question blank. You'll earn one point for every correct answer you choose and zero points for any blank or wrong answers, so it doesn'thurt you to make a guess. If you don't knowan answer and guessit wrong, you'll earn the same number of points that you would have had you left it blank (zero). And if you guessthe question right, you'll earn yourself one point! Now when you're forced to guess on a question for whatever reason, you'll have to decide between thetwo main types of guessing: educated guessing and blindguessing. So let's break down how and when to go about making each type of guess. Educated Guessing You can make an educated guess when you: understand the gist of a question, butdon't have the timeto workthrough it completely, don't quite know how to work through a question completely, or you're torn between a few answer options. But if you've got some idea of what the answer can (and- just as important- what it can't) be, it's time to eliminate some answer choices and make an educated guess. For example, let's look at an ACT math problem: Even if you don't have enough time to completely work through the problem or don't know all the steps, just a little knowledge of lines and slopes will tell usthat the answer will be B, C, or D. Why? Because our given slope is $-{2/3}$and a negative slope will fall down towards the right when drawn through our given point (2, 5). This means we can eliminate answer choices A and E immediately. (Spoiler alert: D is the right answer.) BlindGuessing But let's say you've come up against a question and you have absolutely no clue where to begin. Or maybeyou've got ten seconds left on the clock and fifteen questions still left unanswered. You know that leaving a question blank is tantamount to throwing your points out the window, so now it's time to make a blindguess. There's no time for educated guessing or eliminating answer choices- you just have to fill in a bubble. Butwhen you have to make a blindguess like this (or multiple blind guesses), are you better off choosing C than any other answer choice? Let's see. Don't let their cheerful smiles fool you- three of them are hiding the wrong answer, dun dun DUN. Fact or Fiction: Is C the Most Common Answer on the ACT? The idea that C is the best answer to choose when guess-answering a question on a multiple choice test rests on the premise that ACT answer choices are not truly randomized.In other words, the implication is that answer choice C is correct more often than any other answer choice.After all, if the answer key were truly randomized, then why should C be any more likely to be the right answer than any other option? [Note: the ACT switches between using A, B, C, D (andE on the math section) and F, G, H, J (and K on the math). H is the equivalentto C.] Some (or even many) of your high school teachers likely still design their tests by hand, which means that their answer keys will not be statistically random.No matter how much your teachers try to randomize their choices, human beings are NOT random and cannot properly randomize a series.For instance, a truly random sampling will actually produce bizarre strings of patterns- e.g., five AB’s in a row, or twenty questions without a D- and most people do not (or cannot) create these patterns when they try their best to be â€Å"random.† Fortunately or unfortunately, this is NOT the case on the ACT. Unlike many of the tests you take in high school, ACT answer keys are completely computer generated. And computers are very good at being random. This means that the answer choices will have a statistically even distribution of 1 in 4 for each answer choice letter (or1 in 5 on the math section): there is no most common answer on the ACT. So, ultimately, guessing C (or any letter!) will give you the correct answer only a statistical 25% of the time(20% on the math section). Which meansit's NOT true that choosing C will give you a better rate of success than choosing any other letter for your blind guessing. What to do, then? So How Should You Guess? If C isn't the most common answer on the ACT, then which letter should you guess? The truth is that it doesn't matter which letter you pick, only that you stick to the one you choose. The best strategy,and the one that will maximize your overall point gain,is to pick your favorite letter and fill it infor every blind guess. Maybe that letter is A/F or B/G - it doesn't matter. Just be sure to stick with it every single time. So definitelygo ahead and choose C/H to be your designated letter if you like it best! (Just don't expect C to be any betteran answer choice than A, B, or D.) But maybe you're thinking that sounds completely illogical. Why should you fill in the same letter over and over? Why Does Sticking to One Letter Increase Your Odds of Guessing the Right Answer? Your overall score will improve if you stick to choosing the same letter again and again when making blind guesses. This isbecause people are never truly random. If you’re making "random" blind guesses in a spread, you will almost certainly reduce your overall guesses odds, because your best attempt at random guessing cannot replicate computer-generated randomness. But by sticking to your designated letter when making blind guesses, you are re-introducing an element of randomness. Let’s see this in action to better demonstrate why this works. Scenario: It’s crunch time and you’ve run out of minuteson the clock. You have 15 questions left to goand only a few seconds to bubble in your answers. This means you don’t have time to even look at the questions, so you must try to make the best blind guesses you can and maximize your point-gain. You are left with two options: make a random guess spread, or fill in every letter with the same answer choice. Let’s see how each option does when compared to a real ACT answer guide (in this case, we are using the first 15 answers of the 2015/2016 ACT reading section answers, with all F, G, H, J's converted to A, B, C, D's.) (Note: for our random spread, we tried to guess as randomly as we could without looking at the answer key, and for our consistent letter, we simply went with C.) â€Å"Random† Spread Consistent Guess (C) Correct Answers A C A C C D B C C A C C A C B B C D D C A B C C D C B B C D C C A A C D C C C C C D D C B By choosing a random spread, we earned 2 points out of a possible 15.But by sticking with one answer choice, we earned 4 points. Ultimately, sticking to the sameletter won't work better for each individual question, but on average and over a spread, the strategywill let you maximize your overall point-gain. Oh, statistics, you strange creature. The Take-Aways So is C the most common answer on the ACT? No! But is it the best letter to choose when you're in a bind and don't know what the right answer choice is? Well, that's more complicated. Always remember that it'sin your best bet to eliminate answer choiceswhenever possible. But if you can't, and you must make a blind guess, then stick to one letter and run with it every time. If you want this letter to be C (and it's equivalent, H), then go right ahead! Just make sure you stick with it every single time. C isn't any better or worse than any other letter, or any more likely to be the correct answer, but if you decide to stick with it for every blind guess you make, you'll be better off than trying to be "random." What's Next? Blind guessing strategy is great in a pinch, but elimination is always better!

Underage Alcohol Drinking in Military Essay Example | Topics and Well Written Essays - 1500 words

Underage Alcohol Drinking in Military - Essay Example In the light of the different opinions, it is significant to explore the underage drinking and its effects on the youth in the military. The military should not allow the underage possession and consumption of the alcohol in order to promote discipline and efficient execution of duties. The law prohibits the persons under the age of twenty-one from possessing and consuming alcohol. Specifically, Article XXI of the US Constitution states clearly that any person under the age of twenty-one years should not drink (Arnold-Burger 1). Whether in the military or not, the application of the state and local laws is in an equal measure. The opponents of the underage alcohol use in the military are right to articulate the US and local laws that restrict the youth from liquor. Every person is equal in matters that center on the law. The 1984 National Minimum Drinking Age Act that requires all the states to restrict underage from purchasing or possessing alcohol publicly should ensure the militar y does not permit the youth to consume liquor (Saunders and Rey 95). In this respect, the minimum age of the laws applies to all the state installations including the military. The assertion underpins the point that it will be against the law to allow the underage in the military to engage in the alcohol drinking. In the past, the military has attempted to abide by the law, especially in the US-Mexican border where Mexico allows underage drinking. The same spirit should continue and make the United States a nation that abides by the legislation.

American-Spanish War Essay Example | Topics and Well Written Essays - 750 words

American-Spanish War - Essay Example In the history of the United States, the Spanish-American War (SAW) is one of the most important foreign wars. The result of the war was the victory for the United States, and this victory became possible due to the hard work and efforts of far-sighted Americans, particularly known as â€Å"Navalists†. The contemporary world would have looked quite different today, if the United States had not won this war. The United States was able to defeat Spain so easily because some far-sighted Americans, such as Theodore Roosevelt and Henry Cabot Lodge, were able to develop a strong American fleet. Creating a strong navy was one of the most important ways to protect the national interest and sovereignty of the United States. The navy was to be the backbone of the American power for years to come . The U.S. was able to defeat Spain at considerably low cost as it got prepared better both military and psychologically, to a large extent The background of the war actually propelled the United States to embark on the policy of revenge, and to take wide public opinion. On February 15, 1898, an explosion occurred in the USS Maine, in the Havana Harbor, which led to the war. Another reason was the idea of freeing Cuba from Spanish domination. However, the USA was able to rapidly gain control, and build an empire effectively. After it had drive Spain from Cuba, the United States was able to gain control of Puerto Rico, and eventually Samoa, Guam, Wake Island, Philippines, and then eventually Hawaii . The war only lasted around 3 months, and resulted in very few casualties, around 400 killed and wounded. In fact, the anti-Spanish press was able to raise the public against Spain, which led to mass support, which is essential in wars. Such anti-Spanish press included the â€Å"Yellow Journalism†. ... It was also because of the misrule by Spanish in Cuba, and the misery that it had caused, which led to huge nationalistic outburst.6 The fact that the United States was so strong militarily also paved the way for the swift and relatively easy victory. The U.S did not have to protect any colonies abroad. Additionally, the strong navy was built, which was encouraged by both business and government leaders. A modernization program had been started back in 1881, which had included innovations, which included new ships having steel hulls, large, rifled guns and steam engines. The strong U.S navy was able to defeat Spain easily, because Spain could not compete with the all-steel and steam navy, which had ranked one of the top five navies in the world at that particular period. The Spanish navy was easily defeated. 7 Additionally, the government policies, as well as the high quality of leadership also made Spanish defeat extremely easy. Theodore Roosevelt had a policy, which was summarized â€Å"Speak softly but carry a big stick† showed that there were masterminds behind the development of this plan. The building up of the navy, and the subsequent annexations that the U.S pursued ensured that Spain no longer stood a chance. 8 The Monroe Doctrine also stated that the New World would not be part of foreign colonization, which is why American leadership did not want Spanish presence in Cuba. The leadership eventually turned against Spain, and America’s policies and strength diverted to driving out Spain. Additionally, as historians have examined, Spain was an old and weak country, while the United States was vigorous, new and energetic. It had new strategies.9 As Barrett wrote: â€Å"When Dewey’s squadron sailed out from Mires

Analysing strategic business decisions in us cereal industry

Analysing strategic business decisions in us cereal industry The purpose of this essay is to use game theory and barriers to entry to analyse strategic business decisions in the US ready-to-eat breakfast cereal industry. An industry analysis was done using different published journals. An overview of the oligopoly industry was also done for a broader understanding of the ready-to-eat breakfast cereals industry. Bertrand competition was used as the oligopoly model adopted by the industry. Game theory was used to analyse the strategy firms in the industry will adopt and a discussion on barriers to entry as it applies to the industry was done. Introduction This essay will discuss the US ready-to-eat breakfast cereals industry. An overview of oligopoly, discussions on Game theory, Nash equilibrium, Bertrand Price Competition and Barriers to Entry will be used to analyse the industry and the strategic business decisions as they relate to the industry Analysis of the Ready-to-eat Breakfast Cereals Industry Connor (1999) described the ready-to-eat breakfast cereal industry as a capital intensive industry requiring huge capital investments in production plants. To a large extent, this has contributed to Barriers to Entry in the industry. This industry market structure though having quite a few number of suppliers, is dominated by four major companies which are Kellogg Company, General Mills, Quaker Oats and Kraft. According to Nevo (2000) these companies have consistently continued to post high profits in comparison with the other food industries. A key characteristic feature of this industry is product differentiation. Brand specific knowhow is apparently present since established firms are sometimes unable to duplicate each others brand. The existence of this however, does not prevent them from producing, promoting and distributing successful new brands. Existing brands differ in such potentially relevant dimensions as sweetness, protein content, shape, grain base, vitamin content, fibre content and crunchiness (Schmalnesee, 1978) Connor (1999) has argued that competition in this industry does not involve the use of price war and therefore not a competitive strategy. Different researches conducted on the industry have shown that there is a level of collusion amongst the top firms though not openly done. This assumption was made popular by a case of anticompetitive complaint by the U.S. Federal Trade Commission against the top three manufacturers Kellogg, general Mills Post in the 1970s (Aviv Nevo, 2000) Because of the absence of price wars in the industry, the use of other non-price strategies to gain competitive advantage are employed by firms in this industry. The consistency of zero price wars over the years, however was broken when in the late nineties, a price reduction by Kraft led the other big three Kellogg Company, General Mills and Quaker oats to respond by also reducing their prices as suggested by ( Nevo, 2000). This pricing strategy by Kraft significantly affected the overall industry price forci ng its competitors to reduce their prices as well. Innovation through the launch of new products and aggressive media advertising are strategies employed by firms in the ready-to-eat cereals industry to compete for market share. This is a major factor contributing to the consistent high profits in the industry. The result of Connors (1999) research revealed that the rivalry in the breakfast cereals industry tends towards the choreographed grunts of televised wrestling than a cutthroat dual to the death and that the ultimate weapon, steep price cuts, is rarely unsheathed. According to Connor (1999), media advertising and new product introductions are intimately related. New product introductions are one of the principal mechanisms for effecting rapid price increases in the breakfast cereals industry. His research revealed that all the new cereals introduced by the big four companies between 1981 and 1987 in the first year of sales, were priced 12% above the companys existing brands average prices. Connor (1999) in his research further showed that the extraordinary attachment of consumers to branded cereals (or at least to the boxes they come in) has made entry by private-label products extremely difficult. This high degree of brand loyalty in the industry has significantly posed a threat to any firm considering entry into the industry. Invariably, the more a firms brand is recognised, the higher the sale of a newly introduced cereal will be. The cereal industry has oligopolistic tendencies and characteristics and will be classified as one. An overview on oligopoly below highlights the characteristic nature of oligopoly. Overview of Oligopoly Lipsey + Chrystal (1999) defined oligopoly as the theory of imperfect competition among the few. The industry is characterised by a few firms selling differentiated products. Because there are only few firms, each firm realises that its competitor may respond to any move it makes and takes that into account because each firms decision affects the other firms in the industry. Earl and Wakeley (2005) described firms in the Imperfect competition as having differentiated products which are close substitutes. These differentiated products are supported heavily by advertising. Advertising tends to persuade consumers to patronise a particular brand over other brands of the other competitors. Advertising is used as a crucial weapon to create brand loyalty in the industry as consumers are assumed to be highly mobile. The existence of strong brand loyalty makes entry difficult because consumers are likely to have strong preferences for the already existing brands. This implies that the behaviour of oligopolists are strategic with each firm taking explicit account of the impact of their decisions on competitors and the expected reactions from them (Lipsey + Chrystal, 1999, page 176). Besanko et al (2004) also defined oligopoly as a market in which the actions of individual firms materially affect the industry price level. The strategic behaviour of oligopolists is attributed to the highly competitive nature of the industry. For these firms to make strategic decisions that can give them comparative advantage, they make use of oligopoly models and game theory (Besanko et al, 2004). Game Theory and Bertrand Price Competition Besanko et al (2004) defined Game theory as the branch of Economics that deals with the analysis of optimal decision making when all decision makers are presumed to be rational and each is attempting to anticipate the actions and reactions of its competitors (Besanko et al, 2004, page 36) Game theory is a strategic business decision making tool in areas such as pricing and capacity expansion. Bertrand Price competition Model Besanko et al (2004) has described Bertrand competition as a model of competition in which each firm selects a price to maximize its profit given the price that it anticipates its competitor will select. Each firm views its competitors price as fixed and believes that its own pricing practices will not affect the pricing of the competitor. In an oligopolistic industry with differentiated products, price competition is usually mild. When products are differentiated, a firm will not lose all of its business to competitors that embark on a price cut. This is majorly attributed to competition being based on a variety of product parameters such as its quality, availability and advertising. The US ready-to-eat- breakfast cereal industry like all oligopolistic industries is highly competitive. The strategy of each firm will be to maximize profits and outputs given its rivals strategy. To use game theory to analyse what choice is best for a firm at any given point, two companies will be used; Kellogg Company and General Mills as they are one of the top four and are each others competitors. Game theory and Nash equilibrium will be used to analyse the best strategy for profit maximization given that each firm sets a price for its cereals. A Nash Equilibrium is the strategy combination where each player is doing its best given the strategies of its competitor. An assumption is made that each firm sets a price that maximises its profit and that a price cut by either of them to achieve a larger market share will impact their profits given the strong influence of brand loyalty. The consequences of each firms actions are described in the game matrix below; In the game above, the strategy (Co-operate, Co-operate) is both a Nash equilibrium and a dominant strategy because each firm maximises profit at this point. It is a Nash equilibrium because with the pay-off of ($120, $120) no firm will unilaterally want to deviate knowing that it will achieve a lower pay-off by doing so. Furthermore, co-operate strategy is a dominant strategy because no matter what the other firm chooses, to co-operate will always yield a higher pay-off. Barriers to Entry According to Earl and Wakeley (2005), barriers to entry exist when potential competitors find there are obstacles which hinder their proposed entry into an otherwise attractive industry. Typical barriers to entry include: incumbents owning all sources of essential raw materials; incumbents patents; economies of scale providing incumbents with a cost advantage; and incumbents past expenditure on advertising (which gives them a higher profile in the minds of buyers relative to newcomers). The important point to note about barriers to entry is that they protect all of the industrys incumbent firms from the threat posed by competition from outside of the industry As fierce as rivalries are and as highly competitive as the oligopolistic industry may be in nature, Lipsey + Chrystal (1999) stated that there are determining factors that make a few large firms dominate in the industry. According to Lipsey + Chrystal (1999), some of these factors are natural or structural, and some are firm-created or strategic. These same factors are deterrents to firms seeking entry into an oligopolistic industry. The natural/structural barriers as it applies to the cereal industry include economies of scale, cost of introduction of new brands and economies of scope, and marketing advantages of incumbency, while firm-created/strategic barriers include capacity expansion. Natural/Structural Barriers Economies of Scale According to Besanko et al (2004) production process for a specific product exhibits economies of scale over a range of output when the average cost drops over that range. Economies of scale exist when the unit cost of production declines as the quantity of output increases. When production becomes standardised and highly specialised, the concept of division of labour must be applied. Lipsey + Chrystal (1999) described division of labour as occurring when the production of a product is broken up into hundreds of simple, repetitive tasks. They further stated that the division of labour is, as Adam Smith observed long ago, dependent on the size of the market. If only a few units of products can be sold each day, there is no point in dividing its production into a number of specialised tasks. Lipsey + Chrystal (1999) further stated that larger firms have advantage in industries that have potentials for economies based on the division of labour because the larger the scale of production, the lower their average costs of production. Economies of scale also lead to minimum efficient scale. According to Besanko et al (2004) and Earl and Wakeley (2005) minimum efficient scale is the smallest level of output at which economies of scale cannot be sustained further. Minimum efficient scale can only be achieved in the long run. Based on this, it will be difficult for a firm considering entry to achieve MES because of the costly nature. The cereal industry is capital intensive and is dominated by a large few with the long years of existence. As a strategy to deter entry, the incumbent firms may decide to increase the quantity of output to further drive down their costs and achieve a higher rate of economies of scale. Because economies of scale are present in the industry, the incumbents average cost of production will be lower than that of a new entrant who will have difficulties trying to attain MES which can only be achievable in the long-run. Doing so will entail acquiri ng excess capacity and increasing production output which will both be costly and unprofitable as brand loyalty is extremely high in this industry. Costs of Introducing A New Product and Economies of Scope The cereal industry is categorised by the introduction of new brands. It will be difficult for a firm attempting entry to recover such costs in a short period of time bearing in mind that it will need to break even before making profits. Economies of scope are associated with lower cost scales derived from having multiple production lines within a plant. According to Besanko et al (2004) The ready-to-eat breakfast cereal industry provides a good example. For several decades, the industry has been dominated by a few firms including Kellogg, General Mills, General Foods and Quaker Oats, and there has been virtually no new entry since World War II. There are economies of scope in producing and marketing cereals. Besank0 et al (2004) further explained that for an entry to be successful in the ready-to-eat breakfast cereals industry, the newcomer will need to introduce 6 to 12 successful brands. This requires heavy capital and makes entry a risky proposition. The introduction of new brands is associated with a high cost of advertising. An incumbent firm in the cereal industry can consistently employ the use of introduction of new cereals to deter further entry by new firms. It will not be as expensive for the incumbent firm to advertise its new cereal product as it will be for a new entrant because of the high brand loyalty in the industry and the economies of scope cost advantages. C) Marketing advantages of incumbency Umbrella branding has been described as a situation whereby a firm sells different products under the same brand name (Besanko et al, 2004). According to Besanko et al (2004), an incumbent firm can exploit the umbrella effect to offset uncertainty about the quality of a new product that is been introduced. The umbrella effect may also help the existing firm negotiate the vertical chain. Retailers are more likely to devote scarce warehousing and shelf spaces to the firms new products more than it would for a new entrant. Likewise, suppliers and distributors may be more willing to transact businesses with the incumbent firms more than the new entrant in the areas of credit sales and relationship-specific investments (Besanko et al, 2004). Incumbent firms in the cereals industry can use umbrella branding as a strategy to deter new entry or force new entrants out of the industry. Umbrella branding also has an effect on consumers. The possibility of a newly introduced brands been widely a ccepted by consumers is higher for firms enjoying umbrella branding than for new entrants. Umbrella branding has the ability to reduce uncertainties associated with the introduction of a new cereal brand. Furthermore, the development of close relationships by an incumbent firm with its vertical chain is another strategy for barriers to entry. Firm-Created/Strategic Barriers Capacity Expansion The incumbent firm may decide to embark on capacity expansion. A new entrant will find it difficult to match up its plant size with the plant size of existing firms and may incur losses at entry. With the expansion of capacity and increased sales, the incumbent will continue to enjoy economies of scale thereby forcing new entrants who are unable to achieve such low unit cost of production out of the industry as their average cost of production may consistently be higher than the market price of the cereal brands and the price. Conclusion The ready-to-eat breakfast cereal industry is an oligopolistic industry requiring the firms to employ non-pricing strategies to maximize profits and sustain competitive advantage. Because the ready-to-eat breakfast cereal industry has natural barriers to entry, firms in this industry do not need to do much in the area of strategic barrier to entry to prevent of or force new entrants out of the market. However, the constant introduction of new cereals is crucial to earning higher profits.

Human Resourse Essay

Introduction 1. The Definition and Discrimination of HRM and PM 1.1 The Definition of Human Resource Management  Human Resource Management (HRM) is the function within an organization achieved  the best from their highly motivated people and it is new management techniques to  ensure the effective use of human talent to accomplish organizational goals.   Human Resource Management is the process of recruitment, selection of employee,  providing proper orientation and induction, providing proper training and the  developing skills, assessment of employee (performance of appraisal), providing  proper compensation and benefits, motivating, maintaining proper relations with  labour and with trade unions, maintaining employees safety, welfare and health by  complying with labour laws of concern state or country.   (http://www.whatishumanresource.com/human-resource-management) 1.2 The Definition of Personal Management  Personal Management (PM) is includes the functions that Human Resources staff  perform relative to the organization’s employees and include recruiting, hiring,  compensation and benefits, new employee orientation, training, and performance  appraisal systems. The management of the people in working organizations. It is also frequently called  personnel management, industrial relations, employee relations, manpower  management, and personnel administration. It represents a major subcategory of  general management, focusing exclusively on the management of human resources, as  distinguished from financial or material resources. The term may be used to refer to  selected specific functions or activities assigned to specialized personnel officers or  departments. It is also used to identify the entire scope of management policies and  programs in the recruitment, allocation, leadership, and direction of employees. (http://dictionary.reference.com/browse/personnel+management) 1.3 The difference between Personal Management and Human Resource  Management. Human Resource Management Driven by employer needs for   competitive advantage in the marketplace. Operates within competitive markets and  a change agenda Is a distinctive approach to managing  people, with a strong strategic purpose Adopts a unitary frame of reference to  organisation and people management Manages employees individually rather  than collectively Personnel Management Driven by employer needs to treat people fairly in organisation. Operates in relatively stable market  conditions Is a traditional approach to managing  people, with a strong administrative  purpose Is long term, with a strategic time  perspective  Is short time, with an ad hoc perspective Adopts a pluralist frame of reference to  organisation and people management Negotiates with trade unions where they  are recognized 2. The four major stages of the evolution of Personal and Human  Resource Management. 2.1 Social Justice 2.1.1 Explain the Social Justice The origin of personnel management lies in the 19th Century, deriving from the work  of social reformers such as Lord Shaftesbury and Robert Owen. Their criticism of the  free enterprise system and the hardship created by the exploitation of workers by  factory owners led to the appointment of the first personnel managers. In the late 19th  and early 20th centuries, some large employers began to appoint welfare officers to  manage new initiatives designed to make life less harsh for their employees. The  results were higher productivity, improved retention of the workforce and a bigger  pool of applicants for each job.  2.1.2 Robert Owen (14 May 1771-17 November 1858)  The Industrial Revolution provided the impetus for developing various management  theories and principles. Preclassical theorists like Robert Owen made some initial  contributions that eventually led to the identification of management as an important  field of inquiry. This led to the emergence of approaches to management: classical,  behavioral, quantitative and modern. The classical management approach had three  major branches: scientific management, administrative theory and bureaucratic  management. Scientific management emphasized the scientific study of work methods  to improve worker efficiency. Bureaucratic management dealt with the characteristics  of an ideal organization, which operates on a rational basis. Administrative theory  explored principles that could be used by managers to coordinate the internal  activities of organizations. The behavioral approach emerged primarily as an outcome  of the Hawthorne studies. Mary Parker Follet, Elton Mayo and his associates,  Abraham Maslow, Douglas McGregor and Chris Argyris were the major contributors  to this school.   (http://www.icmrindia.org/courseware/Introduction%20to%20Management/Evolution  %20of%20Management%20Chap2.htm) 2.1.3 Cadbury Cadbury Schweppes employs more than 50,000 people and has manufacturing  operations in more than 35 countries. It is the world’s third largest soft drinks  company and holds either the top or second position in the market share of 24 of the  world’s top 50 confectionery markets. This illustrates that the large Quaker company  has its value in the market where it is important for HR to manage their employee’s  performances, working culture and management in an efficient and positive way.  Resource based model, the SHRM role becomes one of the creating systems and  procedures that focus not on external relationships but on how staff and their abilities  are used. The resource-based model recognizes that many aspects of capability can be  formally defined in skill terms and allows the integration of the intangible aspects of  work alongside other more visible areas such as patents, trademarks and other  intellectual. The core competencies inclu de many things such as aspects change of the  management, capability of staff, strategic development capability and speed of  response. (http://www.ukessays.com/essays/business-strategy/cadbury-strategy.php#ixzz2xjamqFC) 2.2 Human Bureaucracy 2.2.1 Explain the Human Bureaucracy Marked the beginning of a move away from a sole focus on welfare  towards meeting various other organisational objectives. The  fostering of social relationships in the workplace and employee  morale thus became equally important objectives for personnel  managers seeking to raise productivity levels. 2.2.2 Henri fayol (1841-1925) Fayol’s â€Å"14 Principles† was one of the earliest theories of management to be created,  and remains one of the most comprehensive. He’s considered to be among the most  influential contributors to the modern concept of management, even though people  don’t refer to â€Å"The 14 Principles† often today. In 1916, two years before he stepped  down as director, he published his â€Å"14 Principles of Management† in the book  Ã¢â‚¬Å"Administration Industrielle et Generale.† Henri Fayol’s â€Å"14 Principles of  Management† have been a significant influence on modern management theory. His  practical list of principles helped early 20th century managers learn how to organize  and interact with their employees in a productive way. Although the 14 Principles  aren’t widely used today, they can still offer guidance for today’s managers. Many of  the principles are now considered to be common se nse, but at the time they were  revolutionary concepts for organizational management. ï ¼Ë†http://www.mindtools.com/pages/article/henri-fayol.htmï ¼â€° 2.3 Consent by Negotiation 2.3.1 Explain the Consent by Negotiation The elements of hard bargaining or win-lose bargaining were illuminate how to set  aggressive target, start high, concede slowly and employ threats, bluffs, and  commitments to positions without triggering an impasse from 1950s to 1960s. 2.3.2 Collective Bargaining Process The process of negotiating the terms of employment between an employer and a  group of workers. The terms of employment are likely to include items such as  conditions of employment, working conditions and other workplace rules, base pay,  overtime pay, work hours, shift length, work holidays, sick leave, vacation time,  retirement benefits and health care benefits. In the United States, collective bargaining  takes place between labor union leaders and the management of the company that  employs that union’s workers. The result of collective bargaining is called a collective  bargaining agreement, and it establishes rules of employment for a set number of  years. The cost of this employee representation is paid by union members in the form  of dues. The collective bargaining process may involve antagonistic labor strikes or  employee lockouts if the two sides are having trouble reaching an agreement. (http://www.investopedia.com/terms/c/collective-bargaining.asp) 2.4 Organisation and Integration 2.4.1 Explain the Organisation and Integration At the late 19th and early 20th century, there are some social problems in British, which  is social injustice and Rich-poor gap. So British make some legislation on the basis of  economic situation, political democracy, the international environment and social  thoughts. 2.4.2 Race Relations Act 1976 The Race Relations Act 1976 applies to discrimination on the grounds of colour, race,  nationality and ethnic and national origins. It applies in Great Britain but not in  Northern Ireland. Religious discrimination is not explicitly covered in Britain but  separate legislation covers this in Northern Ireland. â€Å"Ethnic origin†, however, has  been interpreted broadly to cover groups with a common or presumed common  identity such as Jews or Sikhs. There are important exceptions to the legislation  which, for example, allow discrimination on grounds of nationality to preserve  immigration controls. Both direct and indirect discrimination are covered by the  legislation which applies to all stages of employment: arrangements made for  deciding who is offered a job; the terms on which the job is offered; opportunities for  promotion, training and transfer; the benefits and services granted to employees; and  in job termination or other unfavourable treatme nt of employees. The Act provides for  a few, specific exemptions where it may be a genuine occupational qualification  (GOQ) to be a member of a particular race, ethnic group, etc. (http://www.eurofound.europa.eu/emire/UNITED%20KINGDOM/RACERELATIONSACT1976RRA-EN.htm) 2.4.3 Disability Discrimination Act 1995 The Disability Discrimination Act (DDA) 1995 aims to end the discrimination that  faces many people with disabilities. This Act has been significantly extended,  including by the Disability Discrimination (NI) Order 2006 (DDO). It now gives  people with disabilities rights in the areas of: employment, education access to goods,  facilities and services, including larger private clubs and transport service buying or  renting land or property, including making it easier for people with disabilities to rent  property and for tenants to make disability-related adaptations functions of public  bodies, for example issuing of licenses.

Essay on Political Debate of Slavery - 1209 Words

During the Antebellum period, the issue of slavery affected many religious and political debates. This was seen in the Lincoln Douglass debates, legislation, and the evolution of political parties. The political debates that fueled the slavery controversy were derived from legislation. The first legislation passed was the three-fifths compromise. Naturally, southern states wanted slaves to be counted as a whole person because the slave population in the south was larger. The northern states opposed this. The three-fifths compromise stated that three out of five slaves would be counted into population counts to determine the amount of representation in Congress. Other constitutional laws included the section that said the slave trade†¦show more content†¦Jackson was the president during the war. In the election of 1844, Henry Clay (who was a Whig candidate) lost to President Harrison. Several Democratic presidents followed; such as, President John Tyler and James K. Polk. The solution to the population problems that the west was finding was solved by Henry Clay. The Compromise of 1850 admitted California as a free state. New Mexico and Utah had a doctrine established o f popular sovereignty. Popular sovereignty allowed the states to choose whether or not to accept slaves or not. The boundary was settled in Texas. The slave trade in Washington D.C. was abolished. A stricter Fugitive Slave Law was placed. President Taylor died and Millard Fillmore (a Whig) came to power. Clearer political parties were drawn. A clear Northern Whig, Southern Whig, Northern Democrat, and Southern democratic line would be seen. Clay died in 1852. This hurt the Whig party in the election of 1852. By this election, the Whig party had separated into the Cotton Whigs and Conscience Whig. The Cotton Whigs leaned toward southern opinion and the Conscience Whigs leaned towards abolitionist opinion. Their main disagreement involved expansion and whether states should be a slave state or not. The Whig’s candidate was Scott and the democratic candidate was Pierce. The Democrats won.
