Econ 1500 - Assignment Example It originated from the classical economists, but later adopted by modern Marxist economics, i.e. Karl Marx. Value exists in three different concepts i.e. utility, use value, and exchange value. In classical economist’s viewpoint, labor input determines the value of a good or service. On the other hand, marginalists believe that a buyer of a good determines its utility, and this fluctuates with consumption patterns. Therefore, the major transition involves labor as the cornerstone of valuation of a product to utility as the form of valuation of a product (Hartwick and Peet 1). Which economists/philosophers derived economic information and theories on â€Å"utility†, the â€Å"equi-marginal principle†, and â€Å"opportunity cost† principles in economics that we use in today’s economic analysis? Identify the concepts and economists, and then briefly explain these three economic principles. Paul Samuelson derived the theory of utility. The concept of utility describes the tastes and preferences associated with consumer’s consumption patterns. This comes from the dual side analysis of value and price i.e. demand and supply sides. Herbert Simon invented the concept of opportunity cost. This is the cost of an activity measured against the foregone value of the next best alternative, i.e. the sacrifice in relation to the next best choice taken among mutually exclusive choices. The principle of equi-marginal utility was the brainchild of Hermann Heinrich Gossen. This concept is an extension of diminishing marginal utility law as it explains how a consumer behaves while distributing his or her limited income between various services and goods. This law dictates that a consumer will allocate his money income among several goods in order to derive maximum

Progressive Era Essay Example for Free

Progressive Era Essay The progressive era was a thirty-year period in which the United States was completely reformed. Actions were taken to improve working conditions for laborers and women. President Roosevelt and Wilson were both reformers for the rights and voice of the people. Theodore Roosevelt used his presidency to put regulations of businesses and make sure the government is still higher than corporations. Individual Reformers and the government in the progressive era went through a great deal to bring about change in the united states, with teddy Roosevelt’s trust-busting and political reform, improvement of laborers and goods, and the restrictions of child labor and women rights. Teddy Roosevelt became known as the great trustbuster. He didn’t get this name for no reason. Roosevelt could identify which trusts were good and which were bad. He could determine which trusts helped the people and which ones hurt them. Roosevelt would hunt down the bad trusts and take them down. He would destroy the bad trusts and restrain the good trusts from becoming bad trusts. Roosevelt believed that the government should police the corporations of America. (A). He took the Sherman Anti-trust act and enforced it so that companies could price their products and make sure not one company could not take control of the market. He did this by creating the Clayton anti-trust act to keep regulations on anti-competiveness. (E) Roosevelt also believed in changing the ways that politicians were elected. Senators in particular were being corrupted because officials were appointing them. He believed that the US senate was just a club basically for high privileged people. This lead to the passage of the seventeenth amendment which said that direct election of senators was to be the new way of choosing who would be in the US Senate. (D) This amendment got the people involved even more with politics and gave them more of a say in government. Politically the government was reformed with the US senate, and the trust busting and making sure that the government was a police force to big corporations. Laborers in the progressive era had it rough. They were not treated with respect, or the consideration that they deserve. The goods that were produced were not of quality and contained harmful hazardous materials. Upton Sinclair was a muckraker who wrote The Jungle, a book about the horribleness of the meatpacking industry. The meatpacking industry was a brutal and unsanitary way of life. The people who worked in the industry were subjected to disease such as tuberculosis and terrible working conditions. The workers were ignorant of the relationship of disease and cleanliness. They didn’t understand that a working condition should be clean and not filled with disease. A lot of the workers had tuberculosis while they worked, and it would get in the meat that they work with, which provided for unsafe meat for people to eat. (B) In other businesses it was just the same. Labors were never treated fairly. Up until recently laborers were not even allowed to go on strike. The government was not helping people; they were staying out of business affairs. Up until the age of reform, and the progressive era. The government was then trying to help out laborers and give them rights. Child laborers and women’s rights were also two big things that came up during the progressive era. Children were expected to work alongside grown men. They were subjected to the same harsh conditions as the adults. Children were not able to be educated because they had to work in the factories. A lot of children only went to school for a short time. The educators acted as if the industrial work was good for children. So children had to go through terrible disease ridden conditions of work. C) The children were not helped by the case of Hammer vs. Dagenhart which ruled that child labor is not a government problem; it is to be judged by the state legislatures. Even some parents felt like it was their kids duty to work, and that the children should work. (G) Eventually however the children were set free from the bondage of labor. But women were still subjected to discrimination. Women at this time didn’t have very many rights. Women want to be treated equally and to have a say in government. Women suffrage was big at this time. They felt like they could not do anything with the life that they had. So they pushed for reform, which was not happening at this time. It was unusual since the progressive era was a big reforming time. (H) The progressive era was a time of great change for the US. It came in the political with the trust busting and the senate voting, it came in the improvement of laborers, and it came in the way child laborers were treated and the women movement. The progressive era was big and it made people really understand what the US was all about.

Stackelberg Leader Follower Models For Strategic Decision Making Engineering Essay

Stackelberg Leader Follower Models For Strategic Decision Making Engineering Essay This paper reviews some Stackelberg Leader-Follower models used for strategic decision making. The simple Stackelberg duopoly is looked at first, and a generalisation of the Stackelberg duopoly problem is given. By studying the models by Murphy et al. (1983) and Smeers and Wolf (1997), the paper reviews Stackelberg model from its classical form to the recent stochastic versions. The paper looks at the mathematical formulation of both a nonlinear mathematical programming model and a nonlinear stochastic programming model. Towards the end of this paper, a simple numeric example is given and practical applications of Stackelberg Leader-Follower models are discussed. Chapter 1: Introduction In economics, an oligopoly is considered to be the most interesting and complex market structure (amongst other structures like monopolies and perfect competition). Most industries in the UK and world- from retailing to fast food, mobile phone networks to professional services- are oligopolistic. Given the current financial climate, it is imperative for firms to be sure that they make decisions accurately, maximising not only their profit, but also their chances of remaining competitive. Many mathematicians and economists have attempted to model the decision making process and profit maximizing strategies of oligopolistic firms. For example, A. A. Cournot was one of the first mathematicians to model the behaviours of monopolies and duopolies in 1838. In Cournots model both firms choose their output simultaneously assuming that the other firm does not alter its output (Gibbons, 1992). Later, in 1934, H. V. Stackelberg proposed a different model where one of the duopoly firms makes its output decision first and the other firm observes this decision and sets its output level (Stackelberg, 1934). The classical Stackelberg model has been extended to model a variety of strategic decision making. For example, Murphy et al. (1983) model the output decision making process in an oligopoly. Later works by Smeers and Wolf (1997) extend this model to include a stochastic element. More interestingly, in a model by He et al. (2009), the Stackelberg theory is used to model the interaction between a manufacturer and a retailer when making decisions about cooperative advertising policies and wholesale prices. The objective of this paper is to review the Stackelberg models from its classic form to the more recent stochastic versions. In chapter 2, the simple Stackelberg duopoly is reviewed and a generalisation of the Stackelberg duopoly problem is given. In chapter 3, more complicated and recent models are reviewed. The mathematical formulation of Murphy et al.s (1983) and Smeers and Wolfs (1997) model is given. At the end of chapter 3, a numerical example is applied to Smeers and Wolfs (1997) model. In chapter 4, practical applications of Stackelberg leader-follower models are discussed. Chapter 4 also looks at the drawbacks of and possible extensions to Stackelberg models. Appendix 1 explains the Oligopoly market structure and economics involved in profit maximisation. Chapter 2: Classical Stackelberg Leader-Follower Model 2.1 Duopoly Behaviour Stackelberg (1934) discussed price formation under oligopoly by looking at the special case of a duopoly. He argued that firms in a duopoly can behave either as dependent on or independent of the rival firms behaviour: Referring to the two firms as firm 1 and firm 2, respectively, firm 1s behaviour can be generalised as follows: Firm 1 views the behaviour of firm 2 as being independent of firm 1s behaviour. Firm 1 would regard firm 2s supply as a given variable and adapts itself to this supply. Thus, the behaviour of firm 1 is dependent on that of firm 2 (Stackelberg, 1934). Firm 1 can view the behaviour of firm 2 as being dependent on firm 1s behaviour. Thus, firm 2 always adapts itself to the formers behaviour (firm 2 views firm 1s behaviour as a given situation) (Stackelberg, 1934). However, according to Stackelberg (1934), there is a difference in the firms actual positions; each of the firms could adapt to either of these two positions, making price formation imperfect. Stackelberg (1934) describes three cases that arise from this situation: Bowler (1924) first described a situation when both firms in the duopoly strive for market dominance. According to Bowler (1924), for this to happen the first firm supplies the quantity it would if it dominated the market with the second firm as a follower. This supply is referred to as the independent supply. By supplying this output level the first firm tries to convince the second firm to view its behaviour as a given variable. However, the second firm also supplies the independent supply since it is also striving for market dominance. This duopoly is referred to as the Bowler duopoly with total supply of the duopoly equalling the sum of two independent supply. According to Stackelberg (1934), the price formation under the Bowler duopoly is unstable because neither of the firms tries to maximise profit under the given circumstance. The second case described by Stackelberg (1934) is a situation where both firms favour being dependent on the other firms behaviour. The first firm would have to match (in a profit maximising manner) its output level to the each output in the second firms feasible set of output. The second firm does the same and both firms are thus followers. This is a Cournot duopoly, first described by A. A Cournot in 1838. According to Stackelberg 1934, the price formation here is unstable because neither of the firms tries to achieve the largest profit under the given circumstance. The third case is a situation where one firm strives for independence and the other favour being dependent. In this case both firms are better off doing what the other firm would like. Both firms adapt their behaviour to maximising profit under the given circumstance. This situation is referred to as the asymmetric duopoly or more commonly as the Stackelberg duopoly. The price formation is more stable in this case because, according to Stackelberg (1934), no one has an interest in modifying the actual price formation. The Stackelberg model is based on the third case of a Stackelberg duopoly. 2.2 The Model In the Stackelberg duopoly the leader (Stackelberg firm) moves first and the follower moves second. As opposed to other models like the Bertrand model and Cournot model where firms make decisions about price or output simultaneously, firms in the Stackelberg duopoly make decisions sequentially. The Stackelberg equilibrium is determined using backwards induction (first determine the follower firms best response to an arbitrary output level by the Stackelberg firm). According to Gibbons (1992), information is an important element of the model. The information in question is the Stackelberg firms level of output (or price, Dastidar (2004) looks at Stackelberg equilibrium in price). The follower firm would know this output once the Stackelberg firm moves first and, as importantly, the Stackelberg firm knows that the follower firm will know the output level and respond to it accordingly. Inspired by the work of Gibbons (1992), Murphy et al. (1983) and Dastidar (2004), a general solution to the Stackelberg game (duopoly) is derived in the parts that follow. 2.2.1 Price function, cost functions, and profit functions Suppose that two firms in a duopoly supply a homogeneous product. Denote the demand function of this market as, where is the total level of output supplied by the duopoly (is the Stackelberg firms output level and is the follower firms output level). The price function can be re-written as. Denote the cost functions (Appendix 1) as for the Stackelberg firm, and for the follower firm. The profit function of the Stackelberg firm is given by: Similarly, the profit function of the follower firm is given by: 2.2.2 Backward induction to derive the best response functions and Stackelberg equilibrium According to Gibbons (1992), the best response for the follower will be one that maximises its profit given the output decision of the Stackelberg firm. The followers profit maximisation problem can be written as: This can be solved by differentiating the objective function and equating the differential to zero (as seen in Appendix 1). Using chain rule to differentiate equation [2] and setting the differential to zero, the following result is obtained: Note that this is a partial differentiation of the profit function since the function depends on the demand function which depends on two variables. Equation [4] gives the followers best response function. For a given the best response quantity satisfies equation [4]. As a result, the Stackelberg firms profit maximisation problem becomes: By differentiating the objective function in equation [5] and equating the differential to zero, the following result which maximises the Stackelberg firms profit is obtained: By solving equation [6] with the follower firms best response profit maximising output, is obtained by the Stackelberg firm given the followers best response. Gibbons (1992) describes as the Stackelberg equilibrium (or the Nash equilibrium of the Stackelberg game). 2.2.3 Example Gibbons (1992) considers a simple duopoly selling homogeneous products. He assumes that both firms are identical and the marginal cost of production is constant at. He also assumes that the market faces a linear downward sloping demand curve. The profit function of the firms is given by: where, with representing the Stackelberg firm and representing the follower firm. Using backward induction, the follower firms best response function is calculated: Solving equation [8]: The Stackelberg firm anticipates that its output will be met by the followers response. Thus the Stackelberg firm maximises profit by setting output to: Solving equation [10]: Substituting this in equation [9]: Equations [11] and [12] give the Stackelberg equilibrium. The total output in this Stackelberg duopoly is. Note: Gibbons (1992) worked out the total output in a Cournot duopoly to be (using this example) which is less than the output in the Stackelberg duopoly; the market price is higher in the Cournot duopoly and lower in the Stackelberg duopoly. Each firm in the Cournot duopoly produces; the follower is worse off in the Stackelberg model than in the Cournot model because it would supply a lower quantity at a lower market price. Clear, there exists a first mover advantage in this case. In general, according to Dastidar (2004), first advantage is possible if firms are identical and if the demand is concave and costs are convex. Gal-or (1985) showed that first mover advantage exists if the firms are identical and have identical downward sloping best response functions. Chapter 3: Recent Stackelberg Leader-Follower Models The classical Stackelberg model has been an inspiration for many economists and mathematicians. Murphy et al. (1983) extend the Stackelberg model to an oligopoly. Later, Smeers and Wolf (1997) extended Murphy et al.s model to a stochastic version where demand is unknown when the Stackelberg firm makes its decision. In a more recent report by DeMiguel and Xu (2009) the Stackelberg problem is extended to an oligopoly with multi-leaders. In this section the models proposed by Murphy et al. (1983) and Smeers and Wolf (1997) are reviewed. 3.1 A Nonlinear Mathematical Programming Version The model proposed by Murphy et al (1983), is a nonlinear mathematical programming version of the Stackelberg model. In their model, they consider the supply side of an oligopoly that supplies homogeneous product. The model is designed to model output decisions in a non-cooperative oligopoly. There are followers in this market who are referred to as Cournot firms (note that from now onwards the follower firms are referred to as Cournot firm as opposed to just follower firms) and leader who is referred to as the Stackelberg firm (as before). The Stackelberg firm considers the reaction of the Cournot firms in its output decision and sets its output level in a profit maximising manner. The Cournot firms, on the other hand, observe the Stackelberg firms decision and maximise their individual profits by setting output under the Cournot assumption of zero conjectural variations (Carlton and Perloff, 2005, define conjectural variation are expectations made by firms in an oligopolistic market about reactions of the other firm). It is assumed that all the firms have complete knowledge about the other firms. 3.1.1 Notations and assumptions For each Cournot firm, let represent the output level. For the Stackelberg firm, let represent the output level (note that is used here instead of, as seen earlier, to distinguish the Stackelberg firm from the Cournot firms). is the total cost function of level of output by Cournot firms and is the total cost function of level of output by the Stackelberg firm. Let represents the inverse market demand curve (that is, is the price at which consumers are willing and able to purchase units of output). In addition to the Cournot assumption and assumption of complete knowledge, Murphy et al. (1983) make the following assumption: and are both convex and twice differentiable. is a strictly decreasing function and twice differentiable which satisfies the following inequality, There exists a quantity (the maximum level of output any firm is willing to supply) such that, For referencing, these set of assumption will be referred to as Assumption A. Assumption 2 implies that the industrys marginal revenue (Appendix 1) decreases as industry supply increases. A proof of this statement can be found in the report by Murphy et al. (1983). Assumption 3 implies that at output levels the marginal cost is greater than the price. 3.1.2 Stackelberg-Nash-Cournot (SCN) equilibrium The Stackelberg-Nash-Cournot (SCN) equilibrium is derived at in a similar way to the Stackelberg equilibrium seen in chapter 2. Using backward induction, Murphy et al. (1983) first maximise the Cournot firms profit under the assumption of zero conjectural variation and for a given. For each Cournot firm let the set of output levels be such that, for a given and assuming are fixed, solves the following Cournot problem: According to Murphy et al. (1983), the objective function in equation [15] is a strictly convex profit function over the closed, convex and compact interval. This implies that a unique optimum exists. The functions can be referred to as the joint reaction functions of the Cournot firms. Murphy et al. (1983) define the aggregate reaction curve as: The Stackelberg problem can be written as: If solves, then the set of output levels is the SNC equilibrium with To get this equilibrium, the output levels need to be determined. Murphy et al. (1983) use the Equilibrating program (a family of mathematical programs designed to reconcile the supply-side and demand-side of a market to equilibrium) to determine: Let the Lagrange multiplier associated with the maximisation problem [19] be. Murphy et al.s (1983) approach here is to determine for which the optimal. The following result, obtained from Murphy et al. (1983), defines the optimal solution to problem [19]: Theorem 1: For a fixed, consider Problem suppose that satisfy Assumption A. Denote by the unique optimal solution to and let be the corresponding optimal Lagrange Multiplier associated with problem [19]. (In case since alternative optimal multipliers associated with problem [19] exist, let be the minimum non-negative optimal Lagrange Multiplier.) Then, is a continuous function of for. is a continuous, strictly decreasing function of. Moreover, there exist output levels and such that and . A set of output levels optimal to Problem, where, satisfy the Cournot Problem [15] if and only if, whence, for. (This theorem is taken from Murphy et al. (1983) with a few alterations to the notation) The proof of this result can be found in the report by Murphy et al. (1983). This theorem provides an efficient way of finding for each fixed. For example, one can simple conduct a univariate bisection search to find the unique root of. 3.1.3 Properties of and Murphy et al. (1983) describes the aggregate Cournot reaction curve as follows: is a continuous, strictly decreasing function of. If the right hand derivative of with respect to is denoted as (the rate of increase of with an increase in ), then for each : The proof to these two properties can be found in the report by Murphy et al. (1983). Murphy et al. (1983) state that if solves the Stackelberg problem [17], then the profit made by the Stackelberg firm is greater than or equal to the profit it would have made as a Cournot firm. Suppose that is a Nash-Cournot equilibrium for the firm oligopoly. is the output the Stackelberg firm would supply if it was a Cournot firm. solves: But since solves the Stackelberg problem [17], the following must hold: In fact, is the lower bound of. The proof to this can be found in Murphy et al. (1983) From assumption 3 in Assumption A, it is clear that. Thus, it is clear that is an upper bound. However, according to Murphy et al. (1983) another upper bound exists. In a paper by Sherali et al. (1980) on the Interaction between Oligopolistic firms and Competitive Fringe (a price taking firm in an oligopoly that competes with dominant firms) a different follower-follower model is discussed. In this model, the competitive fringe is content at equilibrium to have adjusted its output to the level for which marginal cost equals price. Murphy et al. (1983) summarise this model as follows: For fixed and suppose is a set of output levels such that for each firm solves: and For the Stackelberg firm, let satisfy: In addition to Assumption A, if is strictly convex, then a unique solution exists and satisfies conditions [23] and [24]. The Equilibrating Program with a fringe becomes: Theorem 1 holds for with and which implies that. In fact, if is strictly convex, is the upper bound of. Collectively, is bounded as follows: 3.1.4 Existence and uniqueness of the Stackelberg-Nash-Cournot equilibrium Murphy et al. (1983) prove the existence and uniqueness of the Stackelberg-Nash-Cournot (SCN) equilibrium. Their approach to the proof is summarised below: Existence For the SNC equilibrium to exist, and for should satisfy Assumption A. Since is bounded and is continuous (as is continuous), the Stackelberg problem [17] involves the maximisation of a continuous objective function over the compact set. This implies that an optimal solution exists. From Theorem 1 it is seen that a unique set of output levels, which simultaneously solves the Cournot problem [15], exists. As a result the SNC equilibrium exists. Uniqueness If is convex, then the equilibrium is unique. Since is convex, the objective function of the Stackelberg problem [17] becomes strictly concave on. This has been proven by Murphy et al. (1983) and the proof can be found in their report. This implies the equilibrium is unique. 3.1.5 Algorithm to solve the Stackelberg problem Murphy et al. (1983) provide an algorithm in their report to solve the Stackelberg problem. This algorithm is summarised as follows: To start with the Stackelberg firm needs the following information about the market and the Cournot firms: Cost functions of the Cournot firms, satisfying Assumption A. The upper bound as per Assumption A. The inverse demand function for the industry, which also satisfies Assumption A. With this information, the Stackelberg firm need to determine the lower bound and split the interval into grid points with, where and (from [26]). A piecewise linear approximation of is made as follows: Here, is an approximation to and from equation [20] it follows that: Note that at each grid point the approximation agrees with. The Stackelberg problem [17], thus, becomes: can be re-written as: Where and Thus problem [30] becomes: The objective function is strictly concave and solvable. Let be the objective function of the Stackelberg problem [17] and the objective function of the piecewise Stackelberg problem [32], then: Suppose is the optimum level of output. First, suppose that is an endpoint of the interval, then. Now suppose that, that is, . Then needs to be evaluated in order to determine. Theorem 1 can be used here. Recall that is a continuous, decreasing function of. To find the point where (part iii of Theorem 1), the following method is suggested by Murphy et al. (1983): Figure : Method for determining Source: Smeers and Wolf (1997) (alterations made to the notation) First determine using the bounds. Next, determine using the bounds. Then determine using the bounds.Next, determine using the bounds and so on. If then evaluate using the bounds. Having evaluated for some grid points, the game can either be terminated with the best of these grid points as an optimal solution or the grid can be redefined at an appropriate region to improve accuracy. Murphy et al. (1983) go on to determine the maximum error from the estimated optimal Stackelberg solution. This is summarised below: Let be the derivative of with respect to , then: Let be the marginal profit made by the Stackelberg firm for supplying units of output, Let be the actual optimal objective function value in the interval with the estimate being . Then the error of this estimate is defined as: satisfies the following: This concludes the review of Murphy et al.s (1983) nonlinear mathematical programing model of the Stackelberg problem in an oligopoly. 3.2 A Stochastic Version Smeers and Wolf (1997) provide an extension to the nonlinear mathematical programming version of the Stackelberg model by Murphy et al. (1983) discussed in subsection 3.1. In the same way as Murphy et al.s (1983) model, the Stackelberg game in this version is played in two stages. In the first stage, the Stackelberg firm makes a decision about its output level. In the second stage, the Cournot firms, having observed the Stackelberg firms decision, react according to the Cournot assumption of zero conjectural variation. However, Smeers and Wolf (1997) add the element of uncertainty to this process. When the Stackelberg firm makes its decision the market demand is uncertain, but demand is known when the Cournot firms make their decision. This makes the Smeers and Wolfs (1997) version of the Stackelberg model stochastic. Smeers and Wolf (1997) assume that this uncertainty can be modelled my demand scenarios. 3.2.1 Notations and Assumption For the costs functions, the same notations are used. is the total cost function of level of output by Cournot firms and is the total cost function of level of output by the Stackelberg firm. The demand function is changed slightly to take into account the uncertainty. is a set of demand scenarios with corresponding probabilities of occurrence As such, is the price at which customers are willing and able to purchase units of output in demand scenario . has a probability of occurrence. The same Assumption set A discussed in subsection 3.1.1 apply here with alterations made to conditions [13] and [14]. Assumption set A can be re-written as: and are both convex and twice differentiable, as before. is a strictly decreasing function and twice differentiable which satisfies the following inequality, There exists a quantity (the maximum level of output any firm is willing to supply in each demand scenario) such that, For referencing, these set of assumption will be referred to as Assumption B. 3.2.2 Stochastic Stackelberg-Nash-Cournot (SSNC) equilibrium Smeers and Wolf (1997) use the same approach seen before to derive the SSNC equilibrium. The Cournot problem [15]can be re-written as follows: For each Cournot firm and each demand scenario, let the set of output levels be such that, for a given and assuming are fixed, solves the following Cournot problem: Note that is the output level of Cournot firm when the demand scenario is . For each, according to Murphy et al. (1983), the objective function in equation [40] is a strictly convex profit function over the closed, convex and compact interval. The functions can be referred to as the joint reaction functions of the Cournot firms for a demand scenario. The aggregate reaction curve becomes: The Stackelberg problem with demand uncertainty can be written as: Note the Stackelberg problem defined problem [42] differs from that defined in [17]. This is because of the element of uncertainty. The Cournot problem [40] is similar to the Cournot problem [15] because the demand is known when the Cournot firms make their decision. In the Stackelberg problem [42] note the element. This is the estimated mean price, that is, the Stackelberg firm considers the reaction of the Cournot firm under each demand scenario and works out the market price in each scenario, and it then multiplies it by the probability of each scenario. The summation of this represents the estimated mean price. If solves the stochastic, then the set of output levels is the SSNC equilibrium for demand scenario. To get this equilibrium, the output levels need to be determined. Smeers and Wolf (1997) use the same approach as Murphy et al. (1983) in doing so. The Equilibrating program is the same as that in [19], with changes made to the Cournot output and demand function: For each demand scenario , Theorem 1 lays out a foundation on how to solve the Equilibrating program in problem [19] and can also be used to solve [44]. Smeers and Wolf (1997) Summarise Theorem 1 as follows: Theorem 2: For each fixed, An optimal solution for the problem satisfies the Cournot problem [40] if and only if the Lagrange multiplier,, associated with the Equilibrating program [44], is equal to zero. This multiplier is a continuous, strictly decreasing function of . Moreover, there exists and such that: (This theorem is taken from Smeers and Wolf (1997), with a few alteration to the notations) The properties of are the same as those discussed in subsection 3.1.3. The existence and uniqueness of the SSNC equilibrium is shown in the same ways as the SNC equilibrium of Murphy et al.s (1983) model discussed in subsection 3.1.4. 3.2.3 Algorithm to solve the Stackelberg problem The Stackelberg problem here is solved in the same way Murphy et al. (1983) proposed (discussed in subsection 3.1.5). In their report, Smeers and Wolf (1997) do not specify the upper and lower bound of, thus, it is assumed that is bounded by.The interval can be split into grid points with, where and . The piecewise linear approximation of in [27] can be re-written as follows: Here, has the same properties as [29]. The Stackelberg problem [42], thus, becomes: Hereafter, the algorithm summarised in subsection 3.1.5 can be used to solve this problem. 3.3 Numerical Example In Murphy et al.s (1983) report a simple example of the Stackelberg model is given. They consider the case of a linear demand curve and quadratic cost functions: It is assumed that the Stackelberg firm and Cournot firms are identical. The Cournot problem [15] becomes as follow, with as the optimal solution: Solving this problem yields: Note the upper bound of is found by setting. The working to get equation [51] is shown in Appendix 2. The aggregate reaction curve can be written as: Using this information, this example is now extended to Smeers and Wolfs (1997) model with numerical values. Note that the functions listed in equations [49], [50], [51] and [52] satisfy Assumptions A B and other properties discussed in previous sections. Suppose and. And suppose demand is unknown when the Stackelberg firm makes its decision. The cost functions of the firms will be as follows: Figure : Different Demand Scenarios The tables below describe the possible demand scenarios, probability of each scenario occurring, the joint reaction curve and aggregate reaction curve for, and: Scenario, Demand, Probability, = Demand falls, = Demand remains unchanged, = Demand Increases, Scenario, Joint reaction curve, Aggregate reaction curve, Using this information, the Stackelberg problem [42] can be solved. First, the estimated price element can be calculated as follows: Substituting this result back into the Stackelberg problem [42] gives: This problem can easily be solved by differentiating the objective function and finding the value of for which the differential is equal to zero. The working to obtain the following optimal solution is shown in Appendix 2. Using this result, the following result is obtained for each demand scenario: Figure : Optimal Output, Price and Profit 1 260.870 98.02 652.96 147.04 2 260.870 134.39 798.42 201.58 3 260.870 170.75 943.87 256.13 Stackelberg firm Profit, Cournot firm Profit, Industry Profit, 1 21,243.87 12,010.81 69,387.12 2 35,573.12 22,574.95 125,872.92 3 49,802.37 36,444.87 195,581.87 The tables in figure 3 state the SSNC equilibriums for each scenario, and the profits made by each firm in this oligopoly and the total industry profit in each scenario. Note that since is strictly convex, the equilibrium obtained for each scenario is unique. Also note that in all three scenarios, the Stackelberg Output and profit is greater than that of the Cournot firms, illustrating the first mover advantage. Chapter 4: Discussion In this section, the practical applications, drawbacks and possible extensions to Stackelberg models are discussed. 4.1 Practical Applications of Stackelberg models Stackelberg models are widely used by firms to aid decision making. Some examples include: Manufacturer-Retailer Supply Chain He et al. (2009) present a stochastic Stackelberg problem to model the interaction between a manufacturer and a retailer. The manufacturer would announce its cooperative advertising policy (percentage of retailers advertising expenses it will cover-participation rate) and the wholesale price. The retailer, in response, chooses its optimal advertising and pricing policies. When the retailers advertising and pricing is an importan

The Racial Ideology in the NBA Essay example -- Sports, Social Change

NBA (National Basketball Association) is not all about competition. The racial ideology has been present in the NBA. In NBA games, African American people are on display to entertain mainly white Americans. It reminds people of an inappropriate example, in the Colosseum, slaves bloodily fought among themselves or with animals until one’s death while the audiences viewed it as a kind of entertainment. Today, however, American society does not tolerate any downright prejudice, and the NBA helps to build this racial ideology in a more modern and subtle way. Both commercials and commentators are contributing factors to the construction of this racial ideology which has culturally shaped the values of sports. By looking into the historical events and social changes, people can get a greater understanding on this racial ideology in the NBA. After the NBA was founded in 1946, there was, â€Å"the shift from rigid to fluid competitive group relation, changing distributions of power, declining level of overt prejudice and new ideas about assimilation and pluralism† resulting from a civil right movement of the 1950s and 1960s, the urban riots and Black Power movement of the 1960s, briefly, â€Å"the changes in black-white relations in the 20th century† (Healey, 115-116). â€Å"Agricultural work became less labor intensive, and the need to maintain a large, powerless workforce declined†, hence the black laborers came out to urban areas, seeking opportunities (qtd. in Healey, 116). Meanwhile sports as one of several unlimited fields that were opened for African Americans, earned more attention around the countries, especially from the black laborers. Sage noticed, â€Å"in the early 1960s only about 20% NBA players were black, but in 1989 black athletes compr... ...9). Some African Americans compromise to white people who are economically dominating and this phenomenon also depicts supreme white culture, setting African Americans’ status under the white culture. Under the commercial system and influence of the commentary, the racial ideology in the NBA is covert. No one constructed it on purpose, but several inevitable reasons made it happen. Both the historical reasons and traditional stereotypes make African Americans constantly suffer from a racial hierarchy. Practically, what is the best answer to this racial problem? There couldn’t be a short-term and effective way. Nevertheless, with the increasing awareness of the racial problems and the tide of humanities, this racial ideology can be ultimately erased. Just like what happened before, the slavery which was deeply rooted in people’s minds, has been abolished forever.

Analysis of The Sick Rose Written by William Blake Essay -- English Li

Analysis of The Sick Rose Written by William Blake. O rose, thou art sick! The invisible worm That flies in the night, In the howling storm, Has found out thy bed Of crimson joy, And his dark secret love Does thy life destroy. In this essay, I chose to write a bout â€Å"The Sick Rose†, which is a short poem written by William Blake, focusing on the metaphorical language and the symbolism used in it. Though this poem is difficult, I like its deeper meaning and the symbolism. I think that Blake succeeds in giving us a very brilliant work in a few lines. This short poem is a narrative poem made up of two stanzas; each stanza has four lines, rhyming a b c b. The language of it is pretty easy though it is written in 18th century English. The poet uses the present tense to indicate that what he is talking about might happen anytime and anywhere. The tone in the poem is sad. It is set at night, in the â€Å"howling storm.† It has a double meaning. It is full of figurative language. The whole poem is a metaphor. It seems to be about a rose that has been destroyed at night...

Positive Psychology and Kindness

Assessment 1 – Personal Reflection and Sharing / Celebrating with others Happy people become happier through kindness intervention. The relationship between the character strength of kindness and subjective happiness, and the effects of a counting kindnesses intervention on subjective happiness Happy people to perform on their motivation, recognition and enactment of kind behaviors. They have more happy memories in daily life in terms of both quantity and quality. Subjective happiness was increased simply by counting one's own acts of kindness for one week.Happy people became more kind and grateful through the counting kindnesses intervention. Compared with less happy people, happy people have better social relationships and more pleasant everyday lives. For example, very happy people have highly satisfying relationships with friends, romantic partners, and family members and that, compared to their less happy peers, they report more positive events and emotions in their daily lives relative to negative ones. Happy people are more extraverted, more agreeable, and less neurotic.Some studies have shown that subjective happiness is one of the key factors in subjective well-being and overall satisfaction with life. Therefore I expected that in addition to the strength of gratitude, the strength of kindness would also play an important role in increasing subjective happiness. Gratitude is an important human strengths that contributes to subjective happiness, especially appreciative of the contribution of others to their happiness. I suggest that grateful persons would further be characterized by the appreciation of life's simple pleasures.These imply reciprocal relationships among gratitude, subjective happiness, and good social relationships. Consequently, compared with unhappy people, happy people report close and satisfying relationships and feel more gratitude in their lives. Gratitude when people receive kindness form other people, kindness entails enact ing kind behavior toward other people. In personal mindset, how to act of kindness can be expressed in countless ways? A warm hello said to a stranger, giving money to those in need, allowing cars to merge into traffic†¦ all of these are acts of kindness.Kindness may be best expressed as a state of mind. With the holiday season over, and many of us feeling the effects of a far-reaching world disaster, understanding how kindness can help is very important. People you help can see the direct result of your actions, and people who witness your gestures can be touched by what you do. From giving money and time, to the way in which you communicate with friends, family, and co-workers, the ripple effect of kindness is far-reaching.It is easy to think that kindness is only a â€Å"one-way street†, but kindness can go both ways. Giving, in and of itself, can be a great reward, but how is the giver affected? The giver can be rewarded in many areas, both psychologically and physic ally. It would be impossible to list every way that kindness can be shown or given. Being attuned to situations where you can help almost becomes a â€Å"state of mind† or â€Å"attitude† that you can live by. Start by making a list of areas where you can help.This may include giving to a helping organization, such as a local homeless shelter, food-bank, or a national/ international organization. With the natural disaster in the Far East dominating what we see on the evening news, perhaps you could start by identifying national or international organizations that could use your financial donations. You can even look to your community for places that could use your donations or volunteer time, such as visiting patients in a nursing home or hospital ward.Or, for some of this writer's favorites: start with the everyday little things that offer surprises and make people in your nearby community wonder what simple yet amazing acts of kindness are running amok and to get you started, I have listed some ideas below * Pay for the person's order behind you in the drive-through line. * Make eye contact with the person who rings up your groceries and really look at them when you say, â€Å"Have a really great evening. Thank you†. * Compliment at least 2 people every day. * Contrast someone being well mannered and kind, with someone being rude. Send someone a hand written note of thanks * Buy a lottery or Charitable organizations ticket for a stranger. * Give a compliment about your waiter or waitress to his or her manager. * Stop and help someone replace their flat tyre on high-speed road. * Let someone jump the queue at the bank. * Let someone jump the wallets or valuables at the police office. * Treat a friend to the movies for no reason. * Give up your seat for someone, not just an elderly person and pregnancy women. * Talk to a homeless person and have a â€Å"normal† conversation. * Pick up some rubbish in the road which would otherwise b e lying around. Compliment a work colleague for their excellence. * Tell all your family members how much your appreciate them. * Leave a copy of an interesting book on a train. * Buy an inspirational book for a friend. * Send a thank you note to a person who has helped you in the past. * Smile a lot. Kindness is contagious – and as part of Personal Socially Responsibility you might want to consider carrying out random acts of kindness on a daily basis. It is truly a win/win/win situation. The person you are being kind to benefits through your help. You feel good for having helped someone.And the world is a better place through your kindness. Never underestimate the impact of a single act of kindness. I still remember, after many years, the time someone stopped and helped me after my car had broken down in high-speed road. Since then, I have stopped on the road myself and helped stranded motorists a number of times. All because of that single act of kindness by a stranger. Th e implications of kindness are far reaching. Showing kindness even on a small level is a great start. Also, it is important to carry out your acts of kindness without expecting anything in return has its own rewards. 1013 words

Destruction of the Old Order in King Lear Act I

In the first act of King Lear Shakespeare turns the order of world of the play upside down. By the end of the first act virtually every character's station in life has been changed significantly. Lear has given away his power, he has destroyed his family by disowning one daughter and angered another, and he has banished his most trusted advisor. When the play begins, Lear is King of England. He has long ruled and apparently has done so competently. He holds all power in England. Although Lear has advisers, notably Kent and Gloucester, it is clear that Lear is in charge and he keeps his own counsel and makes his own decisions. The play opens with his two advisers, the Earls of Kent and Gloucester being surprised that Lear no longer appears to prefer Goneril's husband the Duke of Albany over Regan's husband Duke of Cornwall. â€Å"I thought the King had more affected the Duke of Albany than Cornwall† (I.i.1-2). Due to his failure to keep his advisers involved in the decision making process, he at times makes rash decisions such as the disowning of Cordelia (I.i.113-116), the dividing of his kingdom between Goneril and Regan (I.i.127-138), and the banishing of his best and most loyal advisor Kent (I.i.173-178). By the end of Act I Lear seems impotent. He is no longer the powerful King of England. He is no longer recognized as King. Goneril has instructed her servant Oswald to â€Å"[p]ut on what weary negligence you please† (I.iii.12) toward Lear. When the once powerful Lear asks Oswald â€Å"Who am I, sir?† (I.iv.78) the servant insolently replies â€Å"My lady's father† (I.iv.79) enraging Lear that a servant should treat him not as king, but as the father of the servant's lady. His power, status, and social standing have collapsed. As a father Lear doesn't fare much better than he did as king. At the play's beginning he is an all-powerful patriarch and expects everyone to completely agree with and cater to his every whim. In many ways he is like a spoiled child. He seeks and demands constant, undivided attention. Lear solicits affection from his daughters â€Å"[w]hich of you shall we say doth love us most,† (I.i.51). When the attention is positive and according to his wishes he exhibits an almost childlike happiness. Although it is evident Goneril and Regan are engaging in hyperbole, Lear is pleased and rewards his two elder daughters with one third of England each. When he asks his favorite daughter Cordelia how much she loves him he is disappointed with her answer and throws a tantrum, â€Å"[h]ere I disclaim all my paternal care† (I.i.113). By the end of the first act Lear's demands have not changed. When Goneril argues with him and complains about the behavior of his knights, Lear has another fit of anger and runs away from Goneril to Regan as if he were a schoolboy running away from home. He no longer is the proud father of three daughters, but has banished Cordelia, angered and run away from Goneril, and pins his hopes on his middle daughter Regan. When Act I ends Lear is no longer the center of social attention. When he first appears on stage the stage directions indicate that a flourish is sounded and Lear enters with his three daughters, his two sons-in-law and an unspecified number of attendants. In the final scene his presence is not announced with a flourish. His daughters and sons-in-law are not present. Lear's only attendants are the banished Kent (disguised as Caius) and Lear's jester known only as â€Å"Fool.† Lear is not alone in his foolish behavior toward his children. Gloucester behaves similarly to Lear. He is used to his power and makes rash, unwise decisions. When the play opens Gloucester appears to be somewhat ashamed of his second son, Edmund who is a bastard for he keeps him away from court, â€Å"he hath been out nine years, and away he shall again† (I.i.32-33). Gloucester's older son Edgar is clearly his favorite. Yet he is quick to believe Edmund when Edmund plots against Gloucester. Edgar clearly mirrors Goneril, as Gloucester is quick to believe the false accusations made by Edmund and force Edgar into hiding. Edgar also mirrors Kent in that he returns in Act II dressed as Poor Tom of Bedlam. As Tom Edgar accompanies his father and helps him just as Kent helps Lear. Cordelia's status changes greatly in the first act. Initially she was Lear's favorite daughter. She went from a highly sought after bride-to-be with a large dowry to a woman with no dowry who is refused by the Duke Burgundy and accepted, without dowry by the King of France. When she refuses to kowtow to Lear with false praise her status is destroyed. Although she clear loves her father she is banished and forced to leave England. By the end of Act I Lear is no longer the proud, powerful King of England. By his own hand he has destroyed his kingdom and his family. Shakespeare has stripped Lear of his armor and has exposed Lear with all of his vulnerabilities and foibles. By removing the old order in the first act, Shakespeare provides a vehicle for the readers and members of the audience to explore the real nature of the characters behind the facades each character displays in public life when the play begins. Each of the characters will reveal his or her true nature throughout the remainder of the play. These revelations provide the tension and the interest of King Lear.

Assignment for Distribution Channel

Assignment for the next class. ( P. S. You are required to split yourselves in group of 6to 8 members each, the details of which shall be collected in class. Students would be called out randomly from each group to present their analysis. In case of a dismal performance of any group member, the marks of the whole group will be at stake! ) 1. The marketing channel for Mary Kay Cosmetics is called a â€Å"direct selling† channel. The company uses a sales force of over 1,000,000 Independent Beauty Consultants around the world.These Consultants are not employees of Mary Kay Corporation; they buy cosmetics from the company at a wholesale price and sell at a retail price to end-users. They maintain personal relationships with their end-user consumers, and deliver product to them after it is ordered; it is a high-service purchasing relationship from the consumer’s point of view. Consultants thus act as both distributors and retailers. a. To what extent does an Independent Beau ty Consultant participate in the eight universal marketing flows? . How might these flows be shifted, either among the members now in the channel or to different agencies or institutions not presently included? What do you think would be the implications of such shifts? (think about how cosmetics are sold through department stores or through drugstore chains, for example) c. Within each of these distribution systems, specify what the consumer's role is from a flow-absorption perspective.Contrast this with the consumer’s role when buying cosmetics from a department store, or a drugstore chain. 2. For each of the three scenarios below, categorize the demand for bulk- breaking, spatial convenience, waiting/delivery time, and assortment/variety as â€Å"High,† â€Å"Medium,† or â€Å"Low. † In each case, explain your answers. a. A woman in an emerging-market country of Southeast Asia wishes to buy some cosmetics for herself.She has never done so before, and i s not entirely sure of on what occasions she will wear the cosmetics. She does not live near a big city. She is too poor to own a car, but has a bit of extra money for a small luxury. b. A manufacturer uses a particular industrial chemical in one of its large-scale production processes and needs to buy more of this chemical. The rest of the raw materials for its plant operations are delivered in a â€Å"just in time† fashion. c.Before you visit certain parts of the world, you are required to get a yellow fever vaccine. Many travelers let this slip until the last minute, forgetting that it is advisable (or avoiding an unpleasant shot as long as possible). But, they definitely realize they need the shot, and don't want to have to cancel their trip at the last minute because they didn't get it. They often find themselves making a long trip to a regional medical center because they didn't plan ahead.

New Deal Section a essays

New Deal Section a essays EXPLAIN THE MAIN FEATURES OF THE NEW DEAL. The New Deal was a series of laws passed by Roosevelt to solve the problems caused in the USA by the Depression. The USA was out of work and almost everyone lost their life saving money and there was no way to achieve it back. A lot of people were also starved during this period. There were four main features of the New Deal. One of the features was to get people back to work and so job creation schemes were set up. The PWA- public works administration to build schools, roads and bridges. The WPA was also set up- public works administration; this was to help on farms and the photography unit. The second main feature of the New Deal was to make people more secure and to protect their savings and property. The Emergency bank act was set up and this closed all the banks. There was also a system to regulate the banks so that the practices that had lost people their savings couldnt happen again. The third main feature was to provide relief or those in trouble, sick, old and unemployed. The Federal Emergency Relief Organisations was really helpful to those listed above, they spent $500 million on soup kitchens, blankets and temporary shelters for the homeless. The last main feature of the New Deal was to get American Agriculture and Industry back on its feet. The AAA- Agricultural Adjustment Act was a group who allowed quotas for crops to keep up prices. Also the NIRA-National Industrial Recovery Administration was set up to improve working conditions in factories. The NIRA also helped with mortgages and they made up laws to help employees. All of these measures were to deal with the problems of the Depression and restore USA to the richest and most powerful country in the world. ...

King Lear Essays - King Lear, British Films, Films, Free Essays

King Lear Essays - King Lear, British Films, Films, Free Essays King Lear The play of King Lear is about a person in search of their own personal identity. In the historical period in which this play is set, the social structure was set in order of things closest to Heaven. Therefore, on Earth, the king was at the top, followed by his noblemen and going all the way down to the basest of objects such as rocks and dirt. This structure was set up by the people, and by going by the premise that anything that is man made is imperfect, this system cannot exist for long without conflict. Through tattered clothes small vices do appear; Robes and furred gowns hide all. Plate sin with gold, And the strong lance of justice hurtles breaks; (IV, vi). The chaos that occurs in King Lear is due the reshaping of bonds within the society. Thus naturally, bonds must be broken, kept and most importantly, formed. This rearrangement of bonds is necessary to Lear understanding his personal identity. Bonds that are broken include those relations between King Lear and his two eldest daughters (Regan and Goneril), between Glouster and Edmund and also between Edmund and Edgar. Lear and Cordelia; Lear and Kent; Glouster and Edgar include those bonds that are existent at both the beginning and conclusion of the play. By the ending of the play, Lear is able to come to terms with himself and with nature. For the rearrangement of the bonds, it is necessary that those based on money, power, land, and deception be to abandoned. In the case of Lear and Goneril and Regan, his two daughters have deceived their father for their personal gain. Furthermore, they had not intended to keep the bond with their father once they had what they wanted. Goneril states We must do something, and i' th' heat. (I, i, 355), meaning that they wish to take more power upon themselves while they can. By his two of his daughters betraying him, Lear was able to gain insight that he is not as respected as he perceives himself to be. The relationship broken between Edmund his half- bother, Edgar and father, Glouster is similarly deteriorated in the interest of material items. By the end of the play, Edgar has recognized who is brother really is and when he has confronted him says the more th' hast wronged me... The dark and vicious place where thee he got/ Cost him his eyes. (V, iii, 203- 207). Since these bonds w ere all based on material items, they were not genuine therefore could not hold in the rearrangement of bonds. Throughout the play some bonds remain true. Lear at first disowns Cordelia because he does not get the flattery from her that he wishes to hear. However, through much torment after he is reduced to nothing, Lear realizes that he cannot always get what he wants just because he is king. Upon such sacrifices, my Cordelia, The gods themselves throw incense. Have I caught thee? He that parts us shall bring a brand from heaven And fire us hence like foxes. Wipe thine eyes. (V, iii, 22- 26) Tough the two were not in communication through the majority of the play, they still had love for each other and by the end of the play, their bond is reformed. The breaking and reforming of Lear and Cordelia's bond is similar to that of Lear and Kent's bond. Throughout the play their bond remains true, only Lear is not aware of it. Even after Lear has passed away, Kent states, I have a journey, sir, shortly to go/ My master calls me; I must not say no. (V, iii, 390- 391), thus proving that even in Lear's death he remains loyal. The bonds that are present at both the beginning and ending of the play have the consistent elements of loyalty and love. Through the reforming of relationships Lear gains insight which allows him to come to terms with himself and nature. Throughout the play Lear experiences much torment and punishment from nature, for unnaturally giving up his power: Blow, winds, and crack your cheeks! Rage, blow! You cataracts and hurricanoes, spout Till you have drenched our steeples, (drowned) the cocks. Your sulph' rous and thought- executing fires, Vaunt- couriers of oak- cleaving thunderbolts, Singe my white

Semiotic Analysis of an Advertisement Essay Example

Semiotic Analysis of an Advertisement Essay Example Semiotic Analysis of an Advertisement Paper Semiotic Analysis of an Advertisement Paper Semiotics is basically a scientific study that revolves around signs and the actual ways in which these specific signs tend to construct and even reconstruct their basic meanings. The nature of a sign can be simultaneously symbolic, indexical and iconic. In a situation whereby the specific sign is iconic, then it means that the sign must be an excellent representation of the respective signified meaning. An example in this case is a photo or a particular painting of an object. In a situation whereby the sign is indexical, it means that there is a direct relationship between the meaning of the sign the specific object that is being signified. An example in this context is; smoke as an index of fire. Lastly, in a situation whereby there is no direct relationship between the sign of a particular object and the meaning, the sign is known as symbolic. An example in this case is; written language which is accurately symbolic. According to Saussure, a sign is composed of two elements: the signifier and the signified. The signifier is basically the kind of image is visually seen. An example in this case is a painting of a particular object. The Signified is basically a specific mental concept that is mainly conjured up in the minds of receivers when they come into an engagement with the signifier. â€Å"A rose is a symbol of love or passion not because a rose looks like love or passion or even because the flower causes it. It is just that members of some cultures have over the years used the rose in certain circumstances to mean love. The first step for signification is the denotative. This is the actual process of description, recognition and the basic identification. Connotation actually tends to look further into the kind of ways in which things are perceived at higher levels. This is helpful because it assists in enabling one to actually go beyond denotations through analysis and interpretation and the addition of facts to the meaning. This article looks at the semiotic analysis and content a nalysis of advertisements. To begin with is a semiotic analysis of a specific of advertisements in the semiotic techniques and terms. In addition to the above, analysis will also explore how things the construction for the meaning has been developed. The name of the magazine is Vogue. Through an advertisement process, the product being advertised tends to become a complete representation of all that the reader would desire it to become. What the advertisement clearly does is thus to signify, to represent to us, the object of desire (Williamson 1978, p. 60). The advertisement to be analyzed is taken from a magazine. Most magazines tend to adapt to their own unique slogans which tend to appear on the cover of the magazine. An example, Marie Claire magazines tend to carry within them the slogan â€Å"for women of the world† and the Cleo magazine has also adopted the name ‘she’s smart, she’s sexy, she’s Cleo’. These types of slogans themselves tend to act as signs and mainly connote the qualities and values such as confidence, youth and even sociability. In the contrary the Vogue magazine has not chosen suck kind of a slogan. The basic reason for this could basically be that the name of the magazine is so significant enough that needs no more elaborations to attract the attentions of the public. The dictionary meaning for the word Vogue is fashion; the latest range; popularity and style. In a situation whereby the actual name of a magazine carries such a significant name and positive connotations, it so unlikely that an additional slogan would exist. As a matter of fact, it is through such kind of names like Vogue that the ideal identities of the feminine gender are clearly exposed. It is an important thing to understand that the general â€Å"the function of women’s magazines is to provide readers with a sense of community, comfort and pride in this mythic feminine identity† (Bignell 1997, p. 61). For analytical purposes Louis Vuitton has been chosen as an advertisement. This advert was basically taken from Vogue Australia Magazine (October, 1998). Vogue is one of the women group magazines that basically aim at reaching out to women from the any particular ethnic background, and are of the age of 18 to 35 having money to actually spend on cosmetics and clothes. Vogue Australia is recognized internationally as the beauty and fashion bible. It should also be realized that the magazine is not only being read by the purchasers but by several other readers too. not all the readers will belong to the group of women which the magazine targets, and some readers will be men (Bignell 1997, p. 58). Most of the messages are basically read in along the way by anyone who gets to perceive them. This type of advert basically shows a very immaculately and smartly dressed blonde woman. The next advertisement is of a good arrangement of ladies cosmetics. This includes the beauty products such as lipsticks, body oils and garments for ladies. This is basically contained in the ELLE magazine on the November issue. This is basically an advert that is mainly intended to attract the female gender since all the products in the picture are used by women. The age category of ladies that the advertisement is supposed to reach is between 20 and 55. This is because some of the items on the advert cannot be used by women who have passed the age of 45 such as â€Å"eye shadow- meant to give color to the eye cover of the ladies. This advertisement is majorly focusing on the ladies of the nature of youths. The advertisement is basically located on the beautiful white background to reveal the exact details of the way the beauty products would appear on a woman. The body of the model in the advertisement is actually facing the front with the body a bit twisted in a figure eight manner. The model has high class beauty wares and is carrying handbags that contain some other beauty products. The third advertisement chosen is a cosmetic advert basically for Lancome. This advertisement was basically taken from Marie Claire magazine. The advertisement was developed during the spring of 1998 was actually more specifically cut from the leaflet with the title Recreate your look with Lancome I actually chose this advertisement for my own personal reasons. I could come across it many times as I could peruse through the different pages of the other magazines. The major dominant object that caught my attention in the advertisement was the ugly nature of the model that was made-up in that particular picture. On personal terms I was not actually impressed by the picture but basically was more fascinated with the picture combinations that were used in the picture. The advert actually spread out through three pages. Page one is actually a photograph of a model has a red-colored hair in the basic front view and actually covers the whole page of the paper. The female model looks to be in the age of 20 and is wearing a shiny silky dress which is blue in color. The model is wearing a type of hat on her head that actually resembles the head of an insect. The hat has blue, turquoise and green colors and are also at the same time acting as a material that the model has used to cover round her neck. The model in the advertisement also has a scarf which is actually has shiny palettes and a shape that is actually spiky. The background of the advertisement is light colored and is dominated by pitch and rose tones. It is amazing that the only conspicuous thing in the advertisement is the pair of wings that are attached on the back of the model. The model seems like she wants to move forward with a very dynamic posture. This design of motion makes the advertisement to have a direct and lively appearance. The direct gazing that the model has actually makes it exaggerated. The model is basically staring directly into the eyes of the viewer. The fist page actually has no additions of text and even no label as concerns the kind of product that is being advertised in the process. As a matter of fact, the viewer is actually left to wonder about the meaning of the image. The page that is actually following the first page show the same woman but this time round wearing a make up that is dark blue and green in color. There is a dark blue rose that is actually shown on the right side of the photograph as the image tends to extend to cover the whole of the second page. Towards the left side of the photograph, the cosmetic product that was being advertised is clearly shown as the brand name which is Lancome is printed in terms of big capital letters and actually spread round the whole area of the two pages. The exact name of the product appears distinctively on the right side of the page as â€Å"Chrysalis, Spring Color Collection 1998† Underneath the texts the images of two lipsticks appear together with pictures of two eye shadows of and their colors printed over the whole area of the white page bringing forth the idea of an insect. This image actually leads the viewer into the image of a beetle which is actually printed towards the letters. Amazingly it seems to be the kind of beetle whose design the model is wearing a necklace in the first photograph. This short description of the advert actually reveals the different types of elements that are involved in the photograph. There is however a weakness in terms of the display of information concerning the photograph as the advertisement does not give any type of information concerning the way by which the individual photograph elements relate to each other and even tend to actually influence one another. In terms of content analysis of the above pictures, according to the dynamic model of Saussure, there are clear indications that there is no exact clear separation between the signified and the actual signifier. There is chance that a given number of signifies could be identified in the process of looking at the picture. One of the identifiers is the woman who is dressed in the insect typology. In terms of the signified the woman’s mental concept is actually represents change that is needed in the society as concerns the product that is actually being advertised. As a female gender, the woman in the picture actually represents the beauty of the conventional beauty in the current society. The only question that rings in the mind of the viewer is that how does the concept of change relate to a woman dressed up in the manner that resembles the one in the photograph? However there is a narrative that is placed actually at the end of the photograph to actually explain the relationship that exists between the signifier and the signified in the photograph as concerns the concept of change. This narrative actually shows that the first woman model in the picture is actually not having any kind of make-up. This is however transformed in the second photograph when the woman model in the picture is shown to be having a make-up resembling that of an insect, preferably a beetle. This basically means or signifies change that the product that is being advertised will make to the people as soon as they use it. The idea that the designer of the photograph is trying to make as concerns the picture to the general viewers is that the product will bring a change in their lives that will make them develop the capacity to be able to move in a speedily manner. This is the reason why the idea of the beetle is brought into the design of the photograph through the model.

Endocrine System Essay Example

Endocrine System Essay Example Endocrine System Essay Endocrine System Essay 1. The normal rat had the fastest radical metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary secretory organ and hence. the normal rat had a faster radical metabolic rate. The consequences turned out to be the manner I predicted them to be. 3. T3 and T4 would be losing in the animal’s blood. 4. I would anticipate to see a lessening in endocrine degrees since the hypophysectomized animate being can non secret ay TSH. Part 2: 5. The normal rat’s BMR increased. 6. The thyroidectomized rat’s BMR increased. However. in comparision to the normal rat. the thyroidextomized rat’s BMR was lower than the normal rat ( intending the normal rat still had a larger BMR ) . The dosage of tetraiodothyronine in the syringe was hence excessively little. 7. The hypophysectomised rat’s BMR increased every bit good. and one time once more. the BMR of the normal rat was still larger and so the dosage was still excessively little. Part 3: 8. The normal rat’s BMR increased from the TSH injections. 9. The thyroidectomized rat’s BMR increased by a small but the BMR of the normal rat was still bigger and so the dosage was excessively little. 10. The hypophysectomised rat’s BMR increased from the TSH. but yet once more. the normal rat’s BMR was still more. so the TSH dosage was once more excessively little. Part 4: 11. The normal rat’s BMR decreased from the PTU injections and it developed the tangible goitre because of physique up of the precursors to thyroxine. 12. The thyroidectomized rat’s BMR was non effected by PTU injections. In this instance. the BMR is still higher than the normal rat’s BMR because of the fact that the thyroidectomized rat had no thyroid secretory organ. 13. The hypophysectomised rat’s BMR was besides non effected by the PTU. and the BMR in this instance was besides more than the normal rat’s BMR because of the fact that the hypophysectomised rat had no pituitary secretory organ.

The fact that these rats are ovariectomized explain their baseline T-scores because these rats have osteoporosis. 2. There was no consequence of saline on the control rat. The consequences of this compared good because this is what I predicted would go on. 3. The disposal of estrogen injections improved the T mark of the estrogen treated rat because it went from -2. 84 to -1. 60. so my anticipation was right. 4. Calcitonin improved the T mark of the calcitonin-treated rat because it went from -2. 84 to -2. 08 and hence. my anticipation was besides right. 5. Some wellness hazards that postmenopausal adult females must see when contemplating estrogen hormone replacing therapy include things such as dementedness. blood coagulums. shots. and different malignant neoplastic diseases such as ovarian malignant neoplastic disease.

EDLE 640 - Assignment 1 - Speech or Presentation Example Therefore, much as we would commit ourselves to achieving our goals or the goals of the organizations we work with, it must all start with loving the other people. Therefore, the first secret to successful leadership, according to Fullan is, Love Your Employees (Fullan, 2008). While being hindered by others in the course of a goal attainment mission, realizing full potential becomes practically impossible. Therefore, the necessity to Connect Peers with a Purpose; which is the second secret to good leadership as discussed by Fullan, becomes necessary. Connecting the peers with ones purpose and objective; personal, professional or organizational, enhances and facilities the goal attainment (Fullan, 2008). Thus connectivity with the people should be much more than just collaborating with them. It requires more of firm interconnection of the peers, and upholding capacity building as the priority for the organization. Facilitating the free social interactions within the peers and creating a favorable environment for them to engage in creativity and innovation, without the fear of being reprimanded for failure, allows individuals to move out of their comfort zones and engage in more risky affairs, which eventually develops full human capacity (Fullan, 2008). While we work towards realizing our goals with the interest of the other people at the fore front, the goal attainment mission becomes justifiable as a personal initiative, and also as a societal collaboration towards a better life for ourselves and for the rest. Social collaboration is enhanced through applying the third secret as discussed by Fullan, which is to ensure Capacity Building Prevails. I have lived in three different countries in the course of my education and professional development; born in Australia, studying in the USA and gaining working experience in London. But in all these movements, I have found that valuing other people is what counts much towards any progress and development, personal, pr ofessional or organizational, since it is only through the support of others, that an individual can realize their full potential, and thus help their organizations to achieve the optimum (Fullan, 2008). Offering leadership and ability demonstration opportunities is fundamental to the development of individuals. Thus, having the mentality that Learning is the Work; forms the fourth secret towards successful leadership. This point to the fact that; learning is the main job within any job, since knowledge and experience improvement forms the basis of career and professional development, as well as personal growth (Fullan, 2008). While individuals are exercising their duties and mandates in the work place, they should not cease to learn, because working with others and through others helps to develop the full potential, and reawakens the talents hidden within an individual’s ability. My first promotion to a high leadership position was when I was 28 years, while teaching at St M ary’s Parish School in Warren, where I was promoted to the rank of Assistant Principal. This enabled me to exercise my teaching roles, while at the same time learning how to lead an institution, an experience that put my everyday as a purely learning day. Within the one year period that I spent as the Assistant Principa

However, to understand the issues being faced in the crisis, one has to first determine the underlying causes that were responsible for the European economic crisis in the first place. Though a number of factors can be said to have been put into play, one major cause is the poor management of the banking systems in countries such as Spain, which left them in dire need of assistance to maintain their operations and remain afloat. This occurred as a result of factors such as lenient lending policies that led to a huge number of defaulters as the economic situation worsened in these countries, meaning the banks were not able to get their money back. The recession that is being faced worldwide also played a big role in the development of the crisis as investors were no longer willing to risk delving into the market due to the fear of losses. The crisis led to a number of outcomes as various markets were affected and were not able to function sufficiently due to the lack of investments. Banks that were not able to regain their money collapsed and even the major ones stumbled as a result of the defaulters while the Euro also dropped in value as a result of people choosing to switch to more stable currencies in their business dealings. Though the UK supports the recovery of the Euro, the steps that have been taken by the European Union, such as the formation of a Single Supervisory Mechanism (SSM) for all banks, may lead to a fading influence of the UK in the Euro Zone. The development of these bodies may lead to the interests of the UK being ignored or overlooked during the voting process on various decisions as the bodies focus on what will help the member states rather than the interests of the UK. As a result, the UK has requested for financial safeguards that

Climate and Air Pollution - Assignment Example The government should introduce tax incentives for companies that adopt the green energy (Dornbusch 62). There should steeper penalties for countries that pollute the environment like oil and gas exploration companies. The Government can open up its market for products produced organically and using green energy. The strategy will encourage companies to shift to green energy to access the market. The strategies will influence the economies differently. Green energy creates jobs encouraging employment of more people (McNamee 108). The trade incentive will encourage more good to be produced to meet the large market demand. Educating the public is crucial. Once people are educated on the importance of green energy, there will be inventions that are beneficial to the economy (Petersons 120). Once green energy is fully adopted effects of global warming will reduce and the money used to tackle disasters channeled

Reflection Essay Example | Topics and Well Written Essays - 250 words - 32

Reflection - Essay Example The three key dimensions in performance expectation include disciplinary core ideas, engineering practices and crosscutting concepts, which will make students successful. Most importantly, NGSS shows more clearly how the integration should occur. Though integration at the lowest grade levels certainly is the most challenging, there are instructional resources that can be used to achieve an interactive orientation. Teachers should actively use the shifts in the NGSS for them to understand them better. The biggest challenge however, is how science and engineering can be integrated into a lesson. This should be the number one problem that requires a solution. To be highly beneficial, the implementation of the changes has to be grounded in the science education vision as outlined in the Framework (NRC 2012) with careful planning and support. A deeper understanding of the framework should be of utmost importance as opposed to rushing through ideas. A comprehensive plan should be developed in consideration of the phases in capacity building before the implementation deadline. The way in which assessment is to be done too has to shift in order to meet the NGSS requirements. The development, approval and implementation of new national and state assessments should take enough time to ensure the assessment is to give the best test to students. Despite the above challenges, the new standards will certainly revitalize science education quality and is also going to be highly supported to bring about a modern outlook of science education. The opportunity should not be squandered by rushing through implementation prematurely. Neither should it be given light treatment while thinking of the shifts as minor, worrying that they cannot be implemented or waiting for the whole system’s components to change. Careful planning together with careful execution is sure going to ensure

The difficulty in obtaining the necessary land and approval only makes the barrier to entry higher making this sector an attractive one. The outlook for the shopfitting market is bleak and is expected to pick up only in the medium and long term, amidst poor consumer sentiments (AMA Research 2005). However, moderate amount of investment is justified by the patronage of a regular client. Expansion in the speculative development market is justified by the low market supply (CPAT 2004). However, this segment is risky and therefore only moderate amount of investment is justified. The three tables below show the three feasible programmes, (1) expand shopfitting and forego speculative development, (2) expand speculative development and forego shopfitting, and (3) moderate amount of investment in both shopfitting and speculative development. As discussed ab ove, the third programme of moderate amount of investment in both shopfitting and speculative development is proposed. Product mix has been discussed previously as the earlier section has identified the most lucrative opportunities that the company can take advantage of. This paper recommends that the company infuse moderate investments in shopfitting and speculative development in order to maximize turnover.
