Jig and Fixture Design

Abstract This paper proposes a design of jigs and fixtures for the mass production manufacturing of Sportsman Race Series aluminum slipper pistons (Probe Industries) that are used in the Chevrolet LS Series V8 engines. The designs of two sets of jig and fixture designs are proposed. The first set (two vee-blocks and a drill bushing) is designed for the process of drilling the wrist pin holes in the piston. The second design (two vee-blocks and a pin locator) is used in the milling of the skirts and lower form of the piston.The designs use principles of manufacturing facilities design, research on manufacturing practices and 3D modeling software (Catia) in order to optimize quality (accuracy), costs and productivity in the manufacture of such pistons. 1. Introduction 1. 1 The Piston An important mechanical component of an internal combustion engine, the piston is basically a solid part in an airtight cylinder that moves under the pressure of a fluid and transfers the force of the expa nding gas to a crankshaft through a connecting rod (The American Heritage, 2005). Pistons typically consist of a few main features.Pistons are cylindrical. The top part of the piston that comes into contact with the expanding gas is the crown. All pistons have a wrist pin hole to contain a steel wrist pin that attaches the piston to a rod that is connected to the crankshaft. The skirt of the piston is the end opposite the crown and is often milled in the sides to reduce weight. 1. 2 Selected Component (Chevrolet LS Series V8 Piston) The specific component chosen for the design project is the Sportsman Race Series aluminum slipper piston (Probe Industries) used in the Chevrolet LS Series V8 engine.The high-speed nature of a V8 engine requires pistons to have reduced weight to improve engine balancing. Unlike older pistons that were made with cast iron, this piston is made with forged aluminum alloy to reduce its weight as well as improve fatigue life. Furthermore, this specific pisto n is a slipper piston with a length of only half its diameter and has some parts milled off in order to reduce size and weight dramatically. 1. 3 Objectives, Scope, and Assumptions The aim of this design project is to design jigs and fixtures for the mass production of the aluminum slipper piston used in the Chevrolet LS Series V8 engine.The scope of the design project is limited to designing jigs and fixtures for the only two processes in the manufacture of such pistons that require jigs and fixtures, specifically the drilling of the wrist pin holes and the milling of the skirts and lower form of the piston. The design project does not account for the exact design, accuracy or efficiency of the drilling and milling machines. The strength and hardness of the materials are not considered. The time and motion in between the processes are not measured for optimization. 2. Manufacturing the Component 2. 1 Component DesignThe exact specifications and design of the piston for the Chevrole t LS Series V8 engine were taken from a manufacturer of such pistons, Probe Industries. The bore (diameter) of the piston is 4 inches and the height is 2 inches. The wrist pin hole is 0. 927 inches in diameter and centered at 1. 155 inches below the crown. The wrist pin length is 2. 5 inches, meaning that the skirt below the oil grooves is milled at each end of the wrist pin hole up to 1. 25 inches away from the center of the cylinder (Probe Industries, 2012). These dimensions are important in the milling and drilling processes in the manufacture of the piston.The image below shows the rest of the dimensions and the tolerances (calculations shown later). 2. 2 Machining Processes in Manufacture of Component After forging a solid aluminum slug into the basic shape of the piston with the desired strength and stability, the component undergoes several machining processes. The first machining process involves using a lathe or a CNC turning machine to make the base, cut out oil rings or g rooves, and drill oil holes. The second process is to drill a large hole on one side of the piston through to the other. This (wrist pin hole) is where the wrist pin is placed to attach the piston to the connecting rod.The third process is to use a milling machine to shave off material at the sides where the wrist pin hole was drilled in order to reduce the weight of the piston. The fourth machining process involves finishing with a lathe machine, wherein the crown is made into its final shape, the bottom edges of the skirt are shaped, and slots/engravings are made. 3. 3 Machining Processes Requiring Jigs and Fixtures The only processes that require jigs and fixtures are the second and third machining processes, the drilling process and milling process. The first and the fourth process use CNC turning/lathe machines and they require no jigs or fixtures.The process of drilling the wrist pin hole however requires a bushing to locate the point in the cylinder that needs to be drilled a s well as a lower vee-block (with a locator at on end) and an upper vee-block (with the bushing and a pin/screw connecting to the lower vee-block) to hold the cylinder. The process of milling requires a lower vee-block as well but with a pin that goes through the wrist pin hole to hold the piston in place in the vee-block. A second, upper vee-block is used to guide the milling machine. The upper and the lower vee-block are referenced to each other with pins. 3.Functional Analysis of Jigs and Fixtures 3. 1 Drilling Process For the drilling process, a vee-block fixture is required to hold and support the cylindrical component. The design of the vee-block includes a locator at the end of the cylinder to keep the piece from moving and to help put the cylinder/piston in the right position. To drill the hole, a bushing is required to guide the drilling machine. The bushing goes through an upside-down vee-block that is put in location by pins connecting it to the lower vee-block. Bushing f or Jig Assembly: Vee-Block for Jig Assembly: Drilling Jig Assembly:Drilling Fixture Assembly (Vee-Block): Drilling Process Jig and Fixture Assembly: 3. 2 Milling Process For the milling process, the piston must be held in the right position and orientation. A vee-block is again used to support the cylindrical piston. And a locating pin is placed in the center of the vee-block at an exact location along it in order to put the piston in the right position along the vee-block and at the right orientation (hole facing upwards) for the milling to be correct (since only the sides with the holes must be milled and only exactly below the oil rings).A thin upside-down vee-block is strapped on to the top of the cylinder and connected to the lower vee-block at an exact location (using pins or screws) in order to hold the piston in place and to keep the milling machine from milling into the oil rings. To mill the other side, the piston is simply turned over and fitted into the locator from the newly milled side. Milling Process Jig (Vee-Block): Milling Process Fixture (Vee-Block and Locating Pin): Milling Process Jig and Fixture Assembly: 4. Tolerance Calculation 4. 1 Tolerance Calculation of Jig and Fixture for Drilling Process To compute or the tolerance of the upper jig of the drilling process, the tolerances of the left and right locating pins and pin holes are computed first. The tolerances and the clearances must be just enough so that both locating pins can fit in the pin holes (in all cases including largest and smallest size of one or both pins and of one or both holes). It should be noted that the worst possible scenario is that on one side of the jig, the hole is the maximum size and the pin is the minimum size while on the other side, the hole is the minimum size and the pin is the maximum size. Given that the diameter of each pin hole in the jig is 12. mm (or 0. 5 inches); the tolerance chosen for this is plus/minus 0. 01 mm (leading to a range of 12. 69-12. 71 mm for the diameter of the hole). A clearance of 0. 05 mm is chosen, causing the largest diameter for the locating pin to be 12. 64 mm. The tolerance chosen for the locating pin is plus/minus 0. 005 mm (leading to a range of 12. 635-12. 645 mm for the diameter of the pin). In the worst case scenario, on one side, the maximum hole size would be 12. 71 mm while the minimum pin size would be 12. 635 mm (leading to a potential gap of 0. 075 mm and a left or right shift of 0. 0375 mm).In the worst case scenario for locating pins where one side has a maximum hole of 12. 71 mm and a minimum pin of 12. 635 mm and the other side of the jig has a minimum hole of 12. 69 mm and a maximum pin of 12. 645 mm, the maximum shift of 0. 0375 mm on either side would still allow the larger pin to fit in the smaller hole since there would still be a gap of 0. 0075 mm (12. 69 – 0. 0375 – 12. 645 = 0. 0075). Since the bushing is screwed on tight into the jig, there is no clearance between the bushing and the jig and thus no need to differentiate between the two pieces in terms of tolerance.The tolerances of the pins and pin holes would cause variation in the position of the drill. The worst case scenario would be if on any side, the pin hole is of maximum size (12. 71 mm) and the locating pin is of minimum diameter (12. 635 mm) leading to a potential gap of 0. 075 mm and a left or right shift of 0. 0375 mm. This shift would cause the drill (center of bushing hole) to move 0. 0375 mm in any direction from the center of the jig, and thus the final wrist pin hole would be plus/minus 0. 0375 mm from the center of the final product (50. 7625 – 50. 8375 mm from the side of the piston and 29. 025 – 29. 3775 mm from the top of the piston). This is within the product specification wherein the tolerance is plus/minus 0. 05 mm (50. 75 – 50. 85 mm from the side of the piston and 29. 29 – 29. 39 mm from the top of the piston). The positions of the loca ting pins and pin holes for the upper and lower vee-block have a tolerance of 0. 005 mm on any direction and thus cause the position of the drilled hole to be between 29. 335-29. 345 mm from the top of the piston and between 50. 795-50. 805 mm from the side of the piston (still within product specifications).The locator on the lower fixture as well as the back plate each has a tolerance of 0. 005 mm combining into a worst case shift of 0. 01 mm and would cause the position of the drill to be between 29. 33-29. 35 mm from the top of the piston (still within product specifications). All the other tolerances of the drilling assembly have no effect. 4. 2 Tolerance Calculation of Jig and Fixture for Milling Process For the milling process, the holes in the upper and lower vee-blocks for the pins that locate the upper vee-block are exactly the same as in the upper jig for the drilling process.Thus the tolerances are the same (0. 01 mm hole tolerance, 0. 05 mm clearance, and 0. 005 mm loca ting pin tolerance) and so is the worst case scenario (shift of 0. 0375 mm). Since the upper vee-block guides the milling machine with a feeler gauge of 0. 01 mm, the worst case scenario would mean that the milled section is either 0. 0375 mm too high or too low on the piston (16. 7625 – 16. 8375 mm from the top of the piston). This is within the product specification wherein the tolerance is plus/minus 0. 05 mm (16. 75 – 16. 85 mm from the top of the piston).As of the lower fixture for the milling process, the symmetrical vee-block allows the cylindrical component to remain centered without rolling even when the size of the component or the fixture varies, thus eliminating the need to set tolerances. However, the tolerance must be calculated for the locating pin that goes through the wrist pin hole since a gap here would cause milling area to move up or down from the top of the piston. The hole that was previously drilled with a diameter of 23. 55 mm is assumed to hav e a tolerance of 0. 01 mm from the drilling process.A clearance of 0. 05 mm is chosen. And the locating pin has a tolerance of 0. 005 mm, thus ranging in size from 23. 49 – 23. 5 mm. In the worst case scenario of a hole with a maximum of 23. 56 mm and a locating pin with a minimum of 23. 49 mm, the potential gap would be 0. 07 mm or a shift of 0. 035 mm up or down the cylinder. This would lead the milling machine to start milling at a point between 16. 765 – 16. 835 mm from the top of the piston. This is within product specification wherein the tolerance is plus/minus 0. 05 mm (16. 75 – 16. 85 mm from the top of the piston).The locations of all the holes and locating pins should have a tolerance of 0. 005 on any direction in order to keep within product specifications. 5. Clamp Selection and Force Calculation For the drilling process, strap clamps are applied on the fixture by using a pair of socket head cap screws on the two sides of the upside-down vee-block. The two socket head cap screws locate the upper vee-block and clamp it to the lower vee-block when holding the work piece piston in place. The diameter of the holes on lower vee-block for screw is 12. 7 mm, thus M12 size socket head cap screws are selected for clamping.The tool force direction of drilling is downward and it has a tool rotation. The strap clamps fasten the upside-down vee-block and the lower vee-block preventing the cylinder from rotational motion and horizontal motion. The tool force can be taken advantage of clamping down the work piece cylinder. According to Spaenaur (2012), the tightening torque of a screw is the product of torque-friction coefficient, nominal screw diameter, and clamping load (T = KDP). The Table 1 has shown that the M12 socket head cap screw has a minimum tensile strength of 160000 pound per inch, and its material is High Carbon Quenched Tempered.In addition, it has a production torque of 125 pound. feet.. Then search this torque data in the re lated Table 2, the clamping force is approximately 13395 pound. For the milling process, the strap clamps are applied by a pair of socket set screws on the two sides of the thin upside-down vee-block. The two socket set screws locate the upper vee-block and clamp it to the lower vee-block when holding the work piece piston in place. The diameter of the holes on lower vee-block for screw is 12. 7 mm, thus M12 size socket set screws are selected for clamping.The table 1 has shown that M12 socket set screw has a minimum tensile strength of 212000 pound per inch, and its material is also High Carbon Quenched Tempered. It has a production torque of 43 pound. feet.. It can be seen in the related table, the clamping force is approximately 4286 pound. For a drilling machine, Pirtini and Lazoglu (2005) has proved that the pressure over the work piece as the cutter moving down into the work piece with same federate remains a constant value, and additional tests have been suggested that the co nstant pressure P(f) (MPa) can be described as a function of feed rate (f) (mm/min).P (f) = 1. 5364f – 103. 06. If the feed rate of the drilling machine is 198 mm/min, then the pressure is 201. 14 MPa. The equation to calculating cutting force is F= P * A. where F is the net force between the measured force and predicted thrust force due to cutting in the thrust direction and A is the contacting area of the cutter at an instant. The force is about 87 kN with the 23. 55 mm diameter drilling hole. For milling machine, we take the piston as an example: Width of cut = 79. 3mm = 3. 122 inch Depth of cut = 19 mm = 0. 748 inch Feed rate = 19. 5 inch/min K† factor =1. 56 MRR = depth of cut x width of cut x feed rate MRR = 3. 122 x 0. 748 x 19. 5 = 45. 54 inch? /min A formula for calculating horsepower (HPC) of the milling cutter is HPC = MRR/K HPC = 45. 54 / 1. 56 = 29. 19 hp The formulas above are from the article ‘A New Milling 101: Milling Forces and Formulas’ ( Brian Hamil, 2011). One metric horsepower can be defined as the power to raise a mass of 75 kilograms against the earth's gravitational force over a distance of one meter in one second. It can be calculated that the tool force is about 21 kN. .

It should be noted that the selling price of the final product ranges between 100-200 AUD. 7. Conclusion It can thus be concluded that in the manufacture of Sportsman Race Series aluminum slipper pistons (Probe Industries) for Chevrolet LS Series V8 engines, jig and fixture assemblies can be used for the two machining processes (drilling the wrist pin hole and milling the bottom form of the piston).The jigs and fixtures designed were basically assemblies of Vee-Blocks with a bushing for the drilling process and another assembly with a locating pin through the wrist pin hole for the milling process. The tolerances were designed in order to not exceed the tolerances in the product specifications. The clamp forces were found to be sufficient and the cost of the jig and fixture is very small compared to the profit made from the final product. The design furthermore is very simple and is thus easily modified to be integrated in a fast-moving assembly line. Therefore it can be concluded that the jig and fixture designs are appropriate. .

Ethical Issues Walmart Paper

There are several factors that account for the changes in the way business is conducted today. Factors such as increased global competition, economic conditions, technology, electronic commerce, workforce diversity, and ethics have all play a significant role in how business is conducted. How a company conducts itself as a business and a corporate citizen is critical to its success. Wal-Mart is the largest retailer in the world; however they are not exempt to acting ethically. In December 2008, Wal-Mart settled 63 laws suits that spans over several years across 42 states accuses Wal-Mart of cheating workers on pay. The settlement cost Wal-Mart $352 million. Based on comments made by Wal-Mart attorneys and spokespeople, it was clear that the company realized that they acted unethically. This paper will provide a brief overview of the ethical issues violated; outline the impact the issues has had on the parties involved and society as a whole; identify the cause or contributing factors to the issue; and finally propose a plan that outlines revised ethical standards and communication methods to prevent the issues from reoccurring. Overview of Ethical Issue. Wal-Mart as a company acted very unethically in this situation. They hired managers to supervise the other employees and not to take advantage of them. The managers were also the one’s acting irresponsible and unethically. Changing the time cards, making the employees work off the clock, is not something that should be done at all. When the managers altered the time cards, they were thinking about now and not the consequences they were going to have to pay. The managers were only thinking about the now and maybe not what the company wanted them to do but they did a selfish act and it hurt the company. The managers possibly could have done this to get more work out of the employees for less money. The article says the employees were forced to work off the clock this is just not ethical in any sense. Maybe the managers had a quota they had to meet and if they met it they would get a bonus. The company has put so much stress on the managers to do the right thing that now it has become an unethical practice. The theory that comes in to play is the goal based theory the managers and the company were only orried about the outcome. Now the company has to worry about all the people coming together and suing the company for lost wages. The impact that this could have on society is that fact that the company may lose the integrity and trust from the public. The company stock may drop so therefore the people that own stock will lose some money. What has happened in the company not only will affect the employees but will affect the business because when society gets word of the things that we re done, the shopping will stop. Prices might even go up so the consumer will have to purchase less and that will always hurt any business when you stifle how much the customer can buy. The theory that comes to mind would be the goal ethical theory because it seems like the managers or the company was only looking out for the outcomes of the business. This type of concern is so unethical because it affects so many other people. This time the employees were affected and the company acted improperly. Ethical Change, Deficiency, and Conflict. Wal-Mart was accused of forcing some hundreds to thousands of current and former workers to work off the clock and exhibiting poor wage practices which resulted in multiple lawsuits in both the federal and state courts. Wal-Mart was accused numerous and various illegal acts of wage practices. The allegations included forcing employees to work unpaid off the clock, erasing hours from time cards, and preventing workers from taking lunch and other breaks that were promised by the company or guaranteed by state laws (Greenhouse & Rosenbloom, 2008). Wal-Mart leadership definitely dropped the ball when attempting to manage within the wage compliance and standardized state laws. Management had the obligation to maintain compliance with all employment and fairness laws and they failed tremendously. If Wal-Mart’s management had responded to these allegations prior to the lawsuits, they could have definitely saved the company millions and their reputation as cheaters. It was their duty to know how the daily operations of each store were being performed and managed. All companies have defined standard operating procedures and a code of ethics and in these cases it was evident that neither was enforced. Their failure of standardized consistency in policies and procedures and lack of management skills were the two major obstacles that caused the company to be plagued with a bad reputation among employees and the public. Management recognized and accepted the responsibility for their mistakes in judgment, and unethical behavior but, as a result of lawsuits. Lessons learned, not so sure, regardless their unethical acts drew major consequences. With the continued embarrassment over these allegations and lawsuits Wal-Mart made the most ethical decision to settle the claims of proposed allegations. Wal-Mart officials have made continuous statements pleading that these illegal and unethical acts took place many years ago and they have made strong strides in reducing wage violations and following the state wage compliance laws and agree to more future improvements. These improvements include such actions as implementing standard of ensuring an employee takes the designated breaks and programming the cash registers to identify when an employee is off the clock. They are making a conscious effort to clean up the wrongs of the past. However, any way you look at it, they were cheating the employees in order to gain company profits. Lawsuits and illegal allegations continue to be a nuisance for the Wal-Mart Corporation, with pending cases alleging sex harassment and forcing employees to miss meals. Again, these are acts from the past but it still outlines the existence of the major inconsistencies with Wal-Mart’s management and their responsibility and ability to maintain a fair and healthy working environment. Future Resolution Wal-Mart has not completely settled the dispute over employee hours worked without compensation. Wal-Mart has tried to make things right with the workers, as well as trying to clean up its image with the public by setting the 63 lawsuits. It will take more than $352 million dollars to make sure this problem does not resurface (Greenhouse & Rosenbloom, 2008). Another incident such as this one could be detrimental to the very existence of Wal-Mart. One solution to the problem would be to unionize Wal-Mart. There are pros and cons to being unionized. Under the protection of a union, Wal-Mart workers will be protected from unethical practices such as uncompensated working hours, sexual harassment, as well as the right to fair pay. Being part of a union would also mean that workers would have the right to health care. In January of 2006 Wal-Mart reported that their health care only incorporated 43% of their employees (Wake-up Wal-Mart, 2005). Wal-Mart does not want to become unionized because it would make the company slightly inflexible. The company would have to adhere to the rules and regulations of the union. One major problem discovered by other companies that became unionized was that workers were less motivated to work for the company and put forth 100% of their efforts. The treat of being fired also went away because under the union rules, in order to terminate an employee for a decline in performance is now regulated under union contract (Free Republic, 2003). Regardless of Wal-Mart’s opposition to become part of a union or not, the company will have to step up efforts to ensure ethical practices are being followed. A set of consequences should be put into action for those managers who violate and infringe upon those rules. Conclusion It is not clear from the article what policies Wal-Mart had in place at the time of the unethical behavior, however the company claims that â€Å"the allegations are not representative of the company we are today† (Greenhouse-Rosenbloom, 2008). The unethical behavior may have been a factor in the company’s highly regarded financial performance. The accusations and these settled cases will serve as precedence for future cases that involve Human Resource and the use of Corporate Resource issues.

Discourse Organization on Asian Fashion Blogs

Discourse Organization of Asian Fashion Blobs Introduction Background of the study Blobbing has emerged as one of the most popular forms of online discourse. The ease and lack of expense in setting blobs has raised intriguing possibilities for language learning in social media. The unique nature of its architecture and its low cost have not only affected how different floggers can publish and distribute their work to a wider audience but also how they see themselves as writers.According to Blood (2002), blobs have been used in various ways: as online Journals, a meaner of signing hypertext's, and more radically, to create what calls the first native form of discourse on the internet. She argues that blobbing best reflects the dream of Tim Burners-Lee (2000), who was one of the principal designers of the World Wide Web, to make the Web into something truly interactive both in terms of how texts are read and how they can be easily posted and accessed.The growing interest in blobbing ha s aroused the interest of English as a Second Language and English as a Foreign Language fashion floggers who see blobbing as a simple and low cost way of giving traders an access to publishing, advertising and distributing their writings on the internet as a method of providing them with the experience of writing in a digital format, and as a meaner of discussing issues related to their social and personal lives. According to Fleischman (2002), blobbing is the art of turning one's own filter on news and the world into something others might want to read, link to, and write about.The openness can give the floggers a greater sense of the variety of possible audiences they can reach, both for understanding these audiences and learning strategies to spoon to them. These types of on-line discussions have been referred to as â€Å"gated communities† (Lowe & Williams, 2004). With regards to world English, Karachi (1992) conceived the idea of three concentric circles of the language . The inner circle represents the traditional bases and is composed of native speakers of English (e. G.United Kingdom, the United States, Australia, New Zealand, Ireland, Anglophone Canada and South Africa, and some of the Caribbean territories). The outer circle includes countries where English is not the native tongue but they use it as a second language (e. . India, Philippines, Singapore, Hong Kong) while those that belong to the expanding circle are the rest of the world where English is used as the primary foreign language (e. G. Russia, China, Japan, Korea, Egypt, Indonesia etc. ). This idea has helped to classify the eight Asian countries that will serve as the subject in this study on how they use English as a language.Kaplan (1966) claims that English writing is characterized by directness and deductive reasoning, while other languages (e. G. Oriental languages and Arabic) favor indirectness and inductive reasoning. At the same time, he attempts to link the differences in discourse organization between English and other languages to their respective cultures and thought patterns. He marked the birth of the notion now known as Contrastive Rhetoric. It assumes that different languages had their own specific and culturally bound conventions and patterns of writing.This may also tell if there are such characteristics in Asian fashion blobs. Moreover, with regards to each Asian flogger's writing style, contrastive rhetoric should also be considered. Contrastive rhetoric is an area of research in second language acquisition that identifies problems in imposition encountered by second language writers and, by referring to the rhetorical strategies of the first language, attempts to explain them. As summarized by Connors (1997), some internal and external forces give rise to this change in perspective.The internal force comes from criticism of contrastive rhetoric, which has required it to go beyond traditional linguistic parameters of analysis to consider discursive features, processes and contexts of writing. The external forces come from new developments in discourse analysis and changing focuses in first language composition research. To enrich further the structure of each blob, genre analysis will also be considered. This may identify if fashion blobbing belongs in a specific genre by studying how the SSL and FEEL floggers use the language when writing. The focus of this study is on the discourse organization of Asian fashion blobs.Considering their writing style, comparing the blobs of these particular Asian countries that are categorized into two groups will be done throughout the study. Statement of the problem This study aims to answer the following questions: 1 . What are the structures of a fashion blob? . What are the similarities and the differences between the fashion blobs of SSL and FEEL writers? Significance of the study College students of English Language Related Programs Knowing that blob can also be studied as it is a part of our social world, this study can still be given more attention by giving further enrichment by the future researchers.They can provide new findings supported by different related literatures. As the traditional way of analyzing language data from academic institutions, this paper will thoroughly investigate the language used in fashion blobs. This will further explore the online discourse by plunging into the grounds of computer-mediated-communication (CM). Researchers in the Field of Linguistics This research paper will be able to support future research papers that are related to discourse analysis, world English, contrastive rhetoric and genre analysis.As most of us today enjoy the web 2. 0 which includes blobbing (http://www.

US Constitution Essay Example | Topics and Well Written Essays - 500 words

US Constitution - Essay Example The President is the head of the Executive branch which is why it is known as the Presidential branch. This branch ensures the proper implementation of Laws as well as administers the affairs of America. The judicial branch consists of the Supreme Court and is responsible to review Laws. The separation of power among the three branches was conducted according to the principles drafted by John Locke and Thomas Hobbes. The Framers of the constitution had taken the decision to divide in an attempt to ensure that the Federal Government has limited power so that the liberties of U.S. citizens were not vulnerable. Furthermore, the separation of power would enable the three branches to keep a check on each other’s activities. This idea of check and balance would ensure that the absolute rights of the citizens were safeguarded. Therefore, the chance of political leaders ignoring the liberties of citizens is narrowed down to zilch. Furthermore, the three branches work together in a hig hly interactive manner to accomplish a single goal i.e. the prosperity of America. (Levy et al 1986) Hobbes strongly believed that the weak needed protection from the strong and thus power should never reside in the hands of a single entity. Originally, the theorist Baron deMontesquieu had suggested using the idea of power separation to protect the rights of citizens. He considered power to be dangerous and stated that if it concentrates in the hands of a single entity than the liberties of citizens would always be ignored and trampled upon. The three branches interact in a unique way which ensures that if a branch tries to out step the constitution, the other two branches immediately declare the act unconstitutional. Therefore, it ensures that the American Constitution has the ability to self govern its responsibilities and maintain the balance of power. Therefore, this ensures that the

Water Pollution Essay Example | Topics and Well Written Essays - 1250 words - 1

Water Pollution - Essay Example ly short, 70 or 80 years, we will not live to see the negative impacts of water pollution because the negative impacts of water pollution will affect the posterity; this idea, however, is a misguided and false idea. This is because water pollution affects us in our daily lives. When we pollute, we are actually causing harm directly to our lives and to the lives of other organisms. When we selfishly pollute water thinking that the pollution of water will not affect us, we are actually destroying our planet, Earth, and there is no way we will be able to have good and quality life if we destroy our planet. Another important point to note is that we should not be selfish and mind our affairs only, but we should also mind the interests of the future generations and the interests of other organisms on planet earth; we should not view ourselves as being more important than other animals and plants, and for that reason we should not pollute water because water pollution causes harm to all li ving organisms, including the future organisms. For that reason, therefore, we should not pollute water, and we should use it wisely for all the organisms on planet earth. The verb "pollute" is derived from the Latin word polluere, which means to foul or corrupt. In reference to water, water pollution means to make water unfit or harmful to living things, especially by the addition of waste matter or sewage, or any other substance that is harmful to biological life. A broader definition of water pollution may include any physical, biological, or chemical change in water quality that adversely affects living organisms or makes water unsuitable for desired uses. We normally pollute water and our environment every day without awareness that we are polluting our environment; for instance, we pollute water and the environment when we use some materials that make water unfit for human consumption and for consumption by other living things; also, we pollute water when we clean our things

The great depression Essay Example | Topics and Well Written Essays - 1500 words

The great depression - Essay Example At the same time, inequality grew by 0.1 percent pushing the poor to worse levels while the rich gained more wealth (Mcquaid 636). Evidently, with the rising personal debts and a consistent production of more goods, a balance was unattainable hence triggering a great depression on the lack Tuesday of October 1929. The stock market crashed leading to the worse economic collapse felt all over the world including various industrialised nations such as Europe. Apart from worsening wages, the great depression led to the closure of 11,000 banks out of 25,000 by 1933 in the United States. Notably, the failure attracted a nationwide loss of confidence in the economy. As a result, many people were not willing to invest or meet the high production at the time. Certainly, this aggravated the spiral downfall hence putting into question the relationship build by America from World War I. historically, America emerged from world war I as a major financier of various countries including Europe. Countries like Germany had been weakened by the war and had to pay for war reparations (Freedman 62). It, therefore, asked for a lot of financial assistance from America, which appeared to be enjoying financial stability. Therefore, many countries that suffered from the great depression mainly had debt or credit related issues with the United States. Germany, for instance, had cases of rising unemployment represented by 6 million people, which is 25% of the e ntire German workforce. The great depression was felt in different countries around the globe. It’s huge effects not only forced a new deal in America but directly led to extremism in Germany and most importantly World War II. As a result various key issues contributed to the fall of world economy. Before the industrialization period, limited Americans had a limited access to the banking sector. However, as industrialization gained momentum more banks came into light. Americans

It is important to note for successfully exporting a product, exporter requires the help and support of not only the importers but also that of the government as well as the transport. For successful completion of export targets, it is therefore critical that the exporter must strike a balance between the two. Further, the risk of high early failures is relatively high as business of this type often fail to materialize properly thus forcing exporters to look for some other alternative channels to continue to operate in the chosen market.

Media Rights for Barclays Premier League in Singapore

Media Rights for Barclays Premier League in Singapore 1. Background Information In 1998, StarHub first introduced the English Premier League to Singapore and has constantly secured broadcasting rights for the past 12 years. During that period, local telecommunications rival, SingTel, has launched their own pay-TV service named mio TV on July 2007, signaling its intention to rival StarHub to be the nations main pay-TV provider. In 2008, SingTel made its first step by securing the media rights to the UEFA Champions League and UEFA Europa League from 2009 to 2012. With the rights for these prestigious European football competitions, many StarHub pay-TV customers were forced to sign up with SingTels mio TV to satisfy their needs. One year on, in October, SingTel rocked the nation by announcing their victory in the bidding war for the media rights for the English Premier League, which is known now as the Barclays Premier League, from 2011 to 2013. The victory was greeted with dismay from many football fans, as they now have to make the jump from StarHubs pay-TV over to mio TV to get their dosage of English football. This effectively ended StarHubs 12-year broadcasting rights of the league, which would certainly result in a fall of subscribers in time to come. 2. Purpose of the Report This report aims to identify the various economic concepts shown in the textbook, and show how they are applicable in the actual business world using the decisions of StarHub and SingTel as examples. 3. The Art and Science of Economic Analysis 3.1 The Economic Problem In the article, it is clearly identified that the resources which led to Starhub bringing in the Barclays Premier League (BPL) to Singapore are human capital and the entrepreneurial ability of the firm. Human capital was shown in the form of knowledge they had on the wants of the locals, and the entrepreneurial ability of StarHub made them realize that they could profit from this project. It was exactly the same two factors that led SingTel to wrestle for the BPL media rights from StarHub. Having observed the huge economic benefits StarHub enjoyed with the monopoly of the BPL media rights in Singapore, SingTel realized they too, would profit hugely from the ownership of the BPL media rights. Thus, SingTel launched a bid to rival StarHub for the rights, which sparked off a bidding war between the two telecommunications firm. Eventually, SingTel earned the rights to broadcast the leagues game for the next 3 years, starting from 2010. 3.2 The Science of Economic Analysis SingTels decision to foray into the Pay-TV market and especially, the market for televised sports like soccer is not due to a normative economic statement, or opinion, made by their staff. Instead, it has been based on a positive economic statement, which is backed by concrete facts. The decision to outbid StarHub for the BPL media rights was greeted by the stock market with changes to the share prices of both firms. StarHubs price dived 16 cents to a low of $2.01 before closing at $2.03 yesterday. SingTels share price rose from $3.25 to $3.31 before closing at $3.28. (A whole new ball game in pay-tv market, 2009, October) This supports the statement that the local market for the BPL is lucrative, as the stock market has made changes to reflect the expected future gains of SingTel, and the foreseen loss of StarHub. Having said so, the change in the share prices are definitely in response to SingTels successful bid, thus eliminating the possibility that the fallacy that association is causation was committed. 4. Economic Tools and Economic Systems 4.1 Three Economic Questions Of course, before the bid was launched, SingTel had to know what to do should they win the bid. Hence, the three economic questions learned in Microeconomics come into play. Firstly, SingTel has identified the broadcasting of Barclays Premier League matches as a service they wish to provide to the nation. Secondly, the launch of mio TV in 2007 paved the way for the bid, with SingTel in the clear that they would use the mio TV as a portal to broadcast programmes, especially the BPL games in the future. With the above two questions answered, SingTels ultimate aim was to overtake StarHub as the nations leading pay-TV provider. Hence, their target market would be the existing subscribers to StarHubs pay-TV, and more notably, the huge number of subscribers to the BPL games and other sports programmes. 4.2 Negative Spillover Costs Negative spillover costs have been incurred with SingTels foray into the local pay-TV market. This is supported by the article which mentioned that SingTels foray into pay TV which split the football content which previously all resided with StarHub actually fuelled soccer fans ire. Thanks to competition between the duo, they said, football fans have to sign up for both StarHub and SingTels pay-TV services to enjoy all of the matches they had previously received when StarHub was the sole pay-TV player. (A whole new ball game in pay-tv market, 2009, October) With that, it is clear that the move by SingTel has not gone down well with sports subscribers of StarHubs pay-TV and has created unnecessary inconvenience. 5. Economic Decision Makers 5.1 The Firm The answers from the three economic questions, namely what service to produce, how and who to produce the service for, reiterates the fact that SingTel is a firm, just like StarHub. Firms are economic units created by entrepreneurs looking to earn money through the combination of the various resources to produce a good or provide a form of service. A more specific term to describe SingTel and StarHub are that they are separate corporations. Corporations are one of the most highly-valued forms of business, often equipped with significant financial power. Funds can be raised quickly through the sale of the corporations stocks, which also leads to the company having an array of stockholders. Behind the strong financial wealth are several drawbacks. Firstly, stockholders are unable to have a significant say in the operations of the corporations with their votes making up only a minority. Instead, a board of directors is often entrusted with the job of making corporate decisions with their bigger shares. Corporate income is also taxed twice, resulting in more profits being used to pay taxes. Despite that, corporate incomes are often huge sums of money, and the taxes would not be able to affect it much. 6. Demand, Supply and Markets 6.1 Demand, Supply and Market Equilibrium for SingTels mio TV For SingTels mio TV, the demand and supply increases by the same value. The increase in demand is attributed to the successful bid of SingTel for the Barclays Premier Leagues media rights. With the media rights, SingTel is able to broadcast the BPL games on their pay-TV service. This would cause a significant increase in the subscribers for mio TV as the subscribers want their dosage of BPL football. This is in line with the taste and preferences of the subscribers, which is a determinant of demand. Hence, there will be a rightward shift for demand. The change in supply for SingTels mio TV is due to SingTels expectations on the future prices of their sports package, which is a determinant of supply. With the hype for the BPL matches present now, it would bring along sales for the sports package. However, in a years time, people might be more interested in other sporting events, and the BPL matches would not appeal as much to the public. As a result, SingTel would then have to reduce their prices to increase sales as the sport package would turn into a luxury product, instead of a necessity. This would see a leftward shift for supply. With an identical shift in the demand and supply curve, the equilibrium price will remain the same. 6.2 Demand, Supply and Market Equilibrium for StarHubs pay-TV For StarHubs pay-TV, a fall in demand has been observed. This is a result of their failure to continue providing Singapore with the BPL matches on their pay-TV service. As such, consumers desperate for their fix of football decided to make the jump to SingTels mio TV due to their taste and preference for the BPL matches. This is the determinant of demand that causes the fall in demand. There is no change reflected in the supply curve as the channels in the sports package are still present. However, the only difference is the removal of the BPL content. Hence, there is no change in supply. As such, the equilibrium price has reduced to account for the fall in demand. 7. Elasticity of Demand and Supply 7.1 Price Elasticity For many Singaporeans, the Barclays Premier League matches are not considered as a necessity to them. Hence, the demand of SingTels sports package is more price elastic to the general public. This means that they are very responsive to changes in the price plans for the matches, and would be unlikely to sign up for the package should it be too pricey. However, to the football fans in the nation, it is a content they are not able to live without. Therefore, the demand of the package is less price elastic to them, suggesting they are not responsive to price changes. This indicates that they would be willing to sign up for the package, regardless of the change in price. 7.2 Income elasticity With the nation recovering quickly from the economic recession, as seen from the recent reports stating that Singapores economy expanded at a stunning pace of 19.3 per cent in the second quarter of 2010. (Singapore economy zooms 19.3% in Q2, 2010, July), the money income of consumers has risen. To them, SingTels sports package is a normal good, as compared to StarHubs sports package, which has been deemed as an inferior good. This is highly due to SingTels success in securing the media rights for the BPL games, which allows them to broadcast the BPL games and other related programmes on mio TV. Thus, with the increase in money income of consumers, they would be more willing to purchase the sports package launched by SingTel. 8. Production and Cost 8.1 Costs in the Long Run and Economies of Scale Firstly, the successful bid for the BPL media rights and ESPN Star Sports brought an increase to the amount of channels available for mio TV. This would indicate an increase in the output by SingTel. Next, average cost for SingTel decreases as they would see an increase in subscribers, especially with football fans rushing to sign up for their sports package. This would cover up the cost incurred between q and qa. Lastly, with the increase in customers for SingTels mio TV service, they would have to increase their plant size to cater to the increase in demand. The plant size could increase in the form of having more service centers around the island, with more technicians and customer service officers hired to meet demands. This would open up the opportunity to create a more extensive division of labour, reflected from qa to q. In the long run, SingTels decision to take over as the exclusive broadcaster of BPL content would enable them to earn a tidy sum of profit. SingTel was not afraid of suffering losses even though StarHub reported that they lose money from providing sports content to pay-TV customers. (A whole new ball game in pay-tv market, 2009, October) They knew that as they were the only pay-TV operator showing BPL content, they would be able to benefit from the media rights with business opportunities coming in from all over the market, including advertising and partnership deals. 8.2 Explicit and Implicit Costs In the case of SingTel, they have incurred both explicit and implicit costs in their decision to outbid StarHub for the BPL media rights. The explicit costs incurred are the money spent on bidding for the exclusive media rights for the Barclays Premier League and the cost of operating mio TV. The implicit costs, also known as the opportunity cost incurred, would be the reduction of their budgets to spend on other genres of programmes. This reduces their ability to bid for other genres of programmes such as primetime blockbusters. 9. Oligopoly Duopoly 9.1 Barriers to Entry With only two pay-TV operators in Singapore, the oligopoly could be identified as a duopoly. A duopoly is a form of oligopoly where only two dominant players are present in a market. As with all kinds of market structure, barriers to entry are in place to deter additional competition. Firstly, there is a high-start up cost involved to enter the pay-TV industry. With bids starting from six-figure sums, a lack of start-up funds would certainly spell the end of the new company as they would not be able to compete with the financial power of StarHub and SingTel. Secondly, StarHub and SingTel have been around for some time, establishing a reputation along the way. The general public is more accustomed to these brands, and any new entrants to the pay-TV market would find it hard to persuade customers to switch to their service. This is true till they are able to force competition through providing exclusive content that the customers demand or other attractive deals. In the case of SingTels mio TV, their original entry to the industry back in 2007 was tough as StarHub was the only established player in the market. SingTels mio TV was finally able to garner the support of customers when they secured the rights to the elite European football competitions. Lastly, the new entrants would probably suffer losses early on, as a large output is required before low production costs can be achieved. This is also known as the economies of scale. The economies of scale would not benefit the new entrants as it takes time to establish high economies of scale. This would put them at a disadvantage as they are unable to effectively compete with the other pay-TV providers. 9.2 Price Leadership Price leadership refers to a player in the market that establishes a price for the rest of the industry to abide to. The player that sets the market price is usually one of the forerunners in the industry, and others in the market would follow suit. This is practiced to avoid price competition as everyones prices will be kept the same. In the case of SingTel, after they have taken over the media rights for the BPL games from StarHub, pressure was inflicted by the public for prices to remain the same. Fans feared that a change in ownership of the rights would cause a hike in the price for BPL matches, due to the exorbitant bid made by SingTel for the rights. Hence, SingTel agreed to maintain the same price that StarHub used to charge for their sports package, appeasing the public. Thus, price competition was not present in this scenario. $25 million StarHub pay-TV SingTel mio TV Raise Raise Maintain Maintain $25 million $20 million $20 million $20 million $25 million $20 million $25 million9.3 Game Theory SingTels huge bid for the Barclays Premier League media rights was not made without any form of theory. Instead, SingTel and StarHubs bids for the BPL media rights could be represented by the game theory. In the game theory presented above, the figures used are generic as the actual bid was not disclosed to the public. The objective of the game theory is to avoid the worst possible outcome, which in this scenario, is losing the bid for the rights. Hence, neither SingTel nor StarHub would think of maintaining their current bid. This is because if the other party decides to raise their bid, it would effectively rule them out of the competition. Thus, neither side would maintain their bid, ruling out the option of both parties maintaining their bids. As such, the only likely choice would be for both telecommunications firm to raise their bid. The difference was that SingTel decided to raise their bid significantly, which outweighed StarHubs raised bid with ease. Hence, SingTel obtained the media rights for the Barclays Premier League. 10. Conclusion In conclusion, SingTel has come a long way to achieve its goal of overtake StarHub as Singapores dominant pay-TV operator in sports. When SingTel first started, they experienced difficulties attracting customers as they were unable to rival what StarHub was able to offer to its subscribers. It was only when they obtained the broadcasting rights for the UEFA Champions League and UEFA Europa League that football-mad customers decided to make the switch to SingTels mio TV. A year ago, SingTel stepped up its attempt to overtake StarHub by outbidding the latter for the BPL media rights for the next three years. Their successful bid enabled them to be the new price leader in the industry, and many football fans from StarHub made the jump from StarHubs pay-TV to SingTels mio TV to get their fix of football. This led to an increase in demand of SingTels mio TV, and a fall in demand for StarHubs pay-TV. Looking at the long term benefits, SingTels costs have been reduced due to an increase in the economies of scale, through establishing more service centers and hiring more workers to meet the increased demand. With a huge number of customers making the switch from StarHub pay-tv to SingTel mio TV due to their need for football, it has allowed SingTel to overtake StarHub as the nations dominant pay-TV operator in sports.

All steel contains carbon, but the term carbon steel applies specifically to steel containing carbon as the main alloying constituents. Medium carbon steel is carbon steel that contains between 0.30 and 0.60 percent carbon. It also has a manganese content of between 0.6 and 1.65 percent. This type of steel provides a good balance between strength and ductility, and it is common in many kinds of steel parts [5]. 3.3.2 Grade 080M30 It can provide a better combination of toughness, strength and hardness. It also provides a counterbalance weight during for low-oscillation rotary process.

National Missile Defense (NMD) Research Paper -- Military Integrated D

National Missile Defense National Missile Defense (NMD) is an extremely complex land-based ballistic missile system with the sole purpose of defending the United States against a ballistic missile attack from a foreign country. The NMD architecture consists of five main components. 1. Ground-Based Interceptors (GBI): The purpose of the GBI is to destroy the incoming nuclear weapon. The interceptor is a multistage rocket, which is launched after receiving a firing solution from the command and control system. After exiting the atmosphere, the Exoatmospheric Kill Vehicle (EKV) is released. This is the actual equipment that is to intercept the incoming warhead and destroy it by colliding with it. The EKV has on-board thrusters that enable it to change course if required to intercept the warhead. 2. Battle Management, Command, Control, and Communications (BM/C3): The BM/C3 component is divided into two main parts. First, the Command and Control (BM/C2) system controls the overall NMD system. Information from sensors is forwarded to the BM/C2, which processes the data and determines the targets for the GBI to intercept. Second, the In-Flight Interceptor Communications System (IFICS) is a network of ground systems that relay communications to the GBI while in flight to guide it to the incoming warhead. 3. X-Band/Ground-Based Radars: These radar systems gather tracking information regarding the incoming warheads during the mid-course phase of the missile. This data is then sent to the BM/C2, which in turn is sent to the GBI for guidance to intercept the warhead. 4. Upgraded Early Warning Radars (UEWR): These radars systems detect targets near the horizon, early in the ballistic missi... ...s?† Coalition to Reduce Nuclear Dangers. 29 Sep 1999. < http://www.clw.org/coalition/ucsnmd092999.htm> 5 Class Notes from website 6 Class Notes from website 7 Gronlund, Lisbeth. â€Å"The Planned US NMD System: Is the Technology Ready for Deployment?

Christopher Marlowes Work and Style Essays -- Biography Biographies E

Christopher Marlowe's Work and Style Christopher Marlowe is a famous Elizabethan poet and playwright. Although often overshadowed by Shakespeare’s popularity, he nonetheless is deserving of attention. Not to dampen the masterpiece of his other works, I believe Marlowe’s unique style is best exemplified in his plays. Marlowe’s plays include Dido, Queen of Cathage, Tamburlaine the Great Parts One and Two, The Jew of Malta, The Massacre at Paris, Edward the II, and The Tragical History of Dr. Faustus. All of Marlowe’s works are unique and astounding in their own ways. Audiences loved the Jew of Malta, and it was performed thirty-six times over the course of four years. Keep in mind that was an amazing record in Marlowe’s time. However, more important to mention may be his great contributions to the art of drama. Marlowe donated two major gifts to drama. The first is the improvement of the blank verse. Some had shunned its use and claimed it was unscholarly. Others used it, but were unable to lift if above commonplace. In such work, it was constructed with isolated lines, one right after another, without grouping according to thought. All of the verses were made after one rhythmical pattern, with the same number of feet and â€Å"caesura† always in place. ( Hopkins 11). Marlowe’s first genius was, â€Å"the invention of numberless variations while still keeping the satisfying rhythm within a recurring pattern. Sometimes he left a redundant syllable, or left the line one syllable short, or moved the position of the caesura. He grouped his lines according to the thought and adapted his various rhythms to the ideas. Thus, the blank verse became a living organism, plastic, brilliant, and finished† (Cutts 19). His se... ...looked by the better-known Shakespeare. From his contributions to drama, which included his use of blank verse and heroic tragedy, to his great themes and characters we see a timeless collection of work and style.

Benito Juarez

Juarez was born in the village of San Pablo Guelatao, Oaxaca on March 21, 1807, located in the mountain range now known as the â€Å"Sierra Juarez†. His parents, Marcelino Juarez and Brigida Garcia, were peasants who both died when he was three years old. Shortly after, his grandparents died as well, in which his uncle then raised him. [2][3] He described his parents as â€Å"indios de la raza primitiva del pais,† that is, â€Å"Indians of the original race of the country. â€Å"[3] He worked in the corn fields and as a shepherd until the age of 12, when he walked to the city of Oaxaca to attend school. 1] At the time, he was illiterate and could not speak Spanish, only Zapotec. In the city, where his sister worked as a cook, he took a job as a domestic servant for Antonio Maza. [1] A lay Franciscan, Antonio Salanueva, was impressed with young Benito's intelligence and thirst for learning, and arranged for his placement at the city's seminary. He studied there but dec ided to pursue law rather than the priesthood. He graduated from the seminary in 1827 and went on to gain a degree in law. In 1843 Benito married Margarita Maza.Benito Juarez with his sister Nela (left) and his wife Margarita (right), 1843 [edit]Political career Juarez became a lawyer in 1834 and a judge in 1841. [4] He was governor of the state of Oaxaca from 1847 to 1852; in 1853, he went into exile because of his objections to the corrupt military dictatorship of Antonio Lopez de Santa Anna. [5] He spent his exile in New Orleans, Louisiana, working in a cigar factory. [6] In 1854 he helped draft the Plan of Ayutla as the basis for a liberal revolution in Mexico. [5] Faced with growing opposition, Santa Anna resigned in 1855 and Juarez returned to Mexico.The winning party, the liberales (liberals) formed a provisional government under General Juan Alvarez, inaugurating the period known as La Reforma. The Reform laws sponsored by the puro (pure) wing of the Liberal Party curtailed the power of the Catholic Church and the military, while trying to create a modern civil society and capitalist economy based on the U. S. model. The Ley Juarez (Juarez's Law) of 1855, for example, abolished special clerical and military privileges, and declared all citizens equal before the law. All the efforts ended on the promulgation of the new federalist constitution.Juarez became Chief Justice, under moderado (moderate) president Ignacio Comonfort. The conservatives led by General Felix Zuloaga, with the backing of the military and the clergy, launched a revolt under the Plan of Tacubaya on December 17, 1857. Comonfort did not want to start a bloody civil war, so made an auto-coup d'etat, dissolved the congress and appointed a new cabinet, in which the conservative party would have some influence, assuming in real terms the Tacubaya plan. Juarez, Ignacio Olvera, and many other deputies and ministers were arrested.The rebels wanted the constitution revoked completely and anothe r all-conservative government formed, so they launched another revolt on January 11, 1858, proclaiming Zuloaga as president. Comonfort re-established the congress, freeing all the prisoners and resigned as president. Under the new constitution, the chief justice immediately became interim president until proper elections could be made. Juarez took office in late January 1858. Juarez then led the liberal side in the Mexican War of the Reform, first from Queretaro and later from Veracruz.In 1859, Juarez took the radical step of declaring the confiscation of church properties. In spite of the conservatives' initial military advantage, the liberals drew on support of regionalist forces. They had U. S. help under some terms of the controversial and never approved McLane-Ocampo treaty. This turned the tide in 1860; the liberals recaptured Mexico City in January 1861. Juarez was finally properly elected president in March for another four-year term, under the Constitution of 1857. Bust of Benito Juarez in Guanajuato, Mexico.Faced with bankruptcy and a war-savaged economy, Juarez declared a moratorium on foreign debt payments. Spain, Great Britain, and France reacted with a joint seizure of the Veracruz customs house in December 1861. Spain and Britain soon withdrew after realizing that the French Emperor Napoleon III used the episode as a pretext to launch the French intervention in Mexico in 1862, with plans to establish a conservative regime. The Mexicans won an initial victory over the French at Puebla in 1862, celebrated annually as Cinco de Mayo (May 5).The French advanced again in 1863, forcing Juarez and his elected government to retreat to the north, first to San Luis Potosi, then to the arid northern city of El Paso del Norte, present day Ciudad Juarez, Chihuahua, and finally to the capital of the state, Chihuahua City, where he set up his cabinet and government-in-exile. There he would remain for the next two and one-half years. Meanwhile Maximilian von Hab sburg, a younger brother of the Emperor of Austria, was proclaimed Emperor Maximilian I of Mexico on April 10, 1864 with the backing of Napoleon III and a group of Mexican conservatives.Before Juarez fled, Congress granted him an emergency extension of his presidency, which would go into effect in 1865, when his term expired, and last until 1867 when the last of Maximilian's forces were defeated. In response to the French intervention and the elevation of Maximilian, Juarez sent General Placido Vega y Daza to the U. S. State of California to gather Mexican American sympathy for Mexico's plight. Maximilian, who personally harbored liberal and Mexican nationalist sympathies, offered Juarez amnesty, and later the post of prime minister, but Juarez refused to accept either a government â€Å"imposed by foreigners†, or a monarchy.A legitimate Mexican throne had existed long before him, founded by Emperor Augustine I after independence had been achieved in 1821, but was abolished o nly a year later, during a domestic crisis. With its own civil war over, President Andrew Johnson invoked the Monroe Doctrine to give diplomatic recognition to Juarez' government and supply weapons and funding to the Republican forces. When he could get no support in Congress, he supposedly had the Army â€Å"lose† some supplies (including rifles) â€Å"near† (across) the border with Mexico.He would not even meet with representatives of Maximilian. Gen. Philip Sheridan wrote in his journal about how he â€Å"misplaced† 30,000 muskets close to Mexico. [7] Faced with this and a growing threat from Prussia, the French troops began pulling out of Mexico in late 1866. Mexican conservatism was a spent force and was less than pleased with the liberal Maximilian. In 1867 the last of the Emperor's forces were defeated and Maximilian was sentenced to death by a military court.Despite national and international pleas for amnesty, Juarez refused to commute the sentence, and Maximilian was executed by firing squad on June 19, 1867 at Cerro de las Campanas in Queretaro. His body was returned to Europe for burial. His last words had been, ‘? Viva Mexico! ‘ Juarez was controversially re-elected President in 1867 and 1871, using the office of the presidency to ensure electoral success and suppressing revolts by opponents such as Porfirio Diaz. Benito Juarez died of a heart attack in 1872 while working at his desk in the National Palace in Mexico City. He was succeeded by Sebastian Lerdo de Tejada, his foreign minister.

Gran Torino Essay

After a while, the two bonded and where Walt helped him through manhood by toughening him up, providing dating advice and helping him get a job in construction. During this, Walt learned that Thao had tried to steal the car to be a part of the gang that he confronted earlier in the movie. Throughout the rest of the movie, the gang had harassed Thao by destroying his construction tools, conducted a drive-by shooting, sexual and physically assaulting Thao’s sister. He then realized that Thao and his sister will never safe as long as the gang is still in the neighbourhood. For this reason, he had gone to the gang member house and committed one final act to help save them. In this paper, the effects of social construction of race and how it is portrayed in the film will be examined. First, the concept of social construction will be analyzed, providing an overview of the definition and its effects. Furthermore, how it is illustrated in the film will be examined. Race as a Social Concept Historically, race has been utilized to differentiate individuals based on their biological and physical appearance. Traits including body shape, skin color and hair style were used to divide individuals into particular racial group (Machery and Faucher, 2005, pp. 1208). However, no empirical evidence exists to supports these classifications. This, in turn shows that differentiations are not rooted biologically or based on getting differences. Rather, the concept of race is explained through process of social construction. Through the lenses of social constructionism, it does not deny the evident physical differences in skin color and characteristics of individuals (Rothenberg, 2008, pp. 10). It simply sees these differences on a continuum of diversity rather than as reflecting innate genetic differences among people† (Rothenberg, 2008, pp. 10). Therefore, race exists due to society’s placing significance on the differentiation between individuals. Effects of Social Construct of Race Takaki stated that â€Å"race†¦has been a social construction that has historically set apart rac ial minorities from European immigrant groups† (as cited in Rothenberg, 2008, pp. 9). Throughout time, the categorization of race had form white hierarchy and domination over other groups of race. This in turn caused an effect of inequality, marginalization and unfair treatment towards particular groups. Asians, Blacks, Aboriginals, and Latinos are among the groups who are subjected to this form of treatment. Some examples include the justification of enslavement of black people, and the denial of access to Canada for non-white individuals. The success behind these social constructs is these divisions of race appear to be natural and a part of everyday lives rendering it to be invisible (Perry, 2011, pp. 16). Thus making it easy to be taken for granted (Perry, 2011, pp. 6). As Michael Omi and Howard Winant (1994) stated, Everyone learns some combination, some version, of the rules of racial classification, and of her own racial identity, often without obvious teaching or conscious inculcation. Thus we are inserted in a comprehensively racialized social structure. Race becomes ‘common sense’—a way of comprehending and being in the world. (as cited in Perry, 2011, pp. 16) Therefore individuals are aware of these divisions but choose to accept it as it has become a natural dynamic in society. Identifying Asian The concept of race is a social process that constructs differences creating divisions among individuals. Throughout time, the classification of certain groups has resulted in prejudice and stereotyping of particular racial groups. This is portrayed in one scene in Gran Torino when Walt was looking with scorn at Thao’s grandmother and said, â€Å"Why the hell do this chinks have to move in this neighborhood for? † (Eastwood, 2009). The protagonist’s use of the word â€Å"chinks† shows the stereotypical label of the Asian community. Chinks† is used to refer to the epicanthic fold found in the inner angle of the eye (wisegeek, n. d. ). This use of this term is associated to the racialization of the Asian race because this difference in appearance was utilized to negatively identify members of this group. Other perceptions in the film include Walt’s snarky comments such as â€Å"aren’t Asians supposed to be smart? Or the assumption as the Hmong as â€Å"jungle people† (Eastwood, 2009). These stereotypical and prejudiced statements are seen extensively throughout the movie. The irony of it is the statements reflect society’s views of the Asian identity. This leads to the notion that through the social process of differentiating groups based on racial traits and characteristics leads to the division of races with the effect of oppressing some. This, sequentially cause the stereotypical and prejudiced associations to be made. If society had not placed a meaning on physical appearance or characteristics, the racial assumption would not exist. Furthermore, if no classification were made towards these individuals, the Asian race will not exist. Youth Asian as Gang Members The Montreal police define a street gang as ‘a group of individuals, usually adolescents and/or young adults, who use the power of group intimidation in order to carry out, on a more or less regular basis, violent criminal acts’ (as cited in Chan and Mirchandani, pp. 116). Police documentation had identified five ethnic groups where street gangs originated (as cited in Chan and Mirchandani, 2002, pp. 117). Among the five is the Asiatic ethnic group (as cited in Chan and Mirchandani, 2002, pp. 117). The process of police construct of race in terms of street gangs involves the process of racialization (as cited in Chan and Mirchandani, 2002, pp. 123). Robert Miles defines it as â€Å"a process of categorization through which social relations between people are structured by the signification of human biological characteristics in such a way as to define and constructs social collectivities† (as cited in Chan and Mirchandani, 2002, pp. 12). It is when negative characteristics, traits and behaviour are associated with particular groups (Jiwani, 2011, pp. 43). This is due the perception and presumed differences of the group (Jiwani, 2011, pp. 43). In terms of the police construction of police, this can be seen through the provision of â€Å"Images of violence-prone ‘ethnic youth’ from war-torn countries (it is taken as given that the ‘ethnic youth’ in question are male) (as cited in Chan and Mirchandani, 2002, pp. 123). When compared to children in Quebec, Ontario, a police man stated â€Å" ‘ Here in [Quebec] our kids are born with a hocky puck in their hand, but there [a country of origin of immigrants] they come into the world with a grenade in their hands† (Symons, 2002, pp. 18)†The culture belief portrays the racialization of the street gang issue (Symons, 2002, pp. 118). The ideology that street gangs originated from the upbringing in a war-torn country signifies street gangs as an immigration issue. As another police stated â€Å"‘They have guns there [in country of origin],â€⠄¢Ã¢â‚¬ ¦ ‘It’s part of their more’† (Symons, 2002, pp. 118). This is seen with the portrayal of the Hmong gang in Gran Torino. Earlier in the film, Sue had shared to Walt that the reason they resided in America and is to escape the violence that is occurring in their homeland (Eastwood, 2009). By providing this background story of escaping a war torn country and the portrayal of young Asiatic gangs terrorizing the neighborhood, supports the racialization of Asiatic gang members. This has come from the social process of constructing that living a life in a war-torn country makes the individual a gang member. Since this living condition is associated with the Asian youth, these members are automatically perceived as a gang member. Other scenes in the film include the portrayal of the ethnic group Latinos as gang members, which are also identified as the patent of street gangs Minority groups and Immigrants as Criminals A key stereotype of Asians race is that of the mysterious, devious, fearsome Asian† (Zong and Perry, 2011, pp. 115). This consecutively marks the group as different and foreign which causes them to be feared and avoided. (Zong and Perry, 2011, pp. 115). Within society this is reflected through minorities and immigrants being â€Å"over police and under protected† by the criminal justice system (as cited in Chan and Mirchandani, 2002, pp. 69). Often times, during the legal process, immigrants are provided longer sentences and severe punishments compare to those who have lived in Canada for 20 years and more (Chan and Mirchandani, 2002, pp. 8). In terms of other minority groups, Blacks and Aboriginals are overrepresented in the correctional system ((Zong and Perry, 2011, pp. 115). Individuals in society are aware of these unfair treatments, but many still links race and crime together. This is due to the belief and perception of immigrants and minorities as dangerous and different. It is important to note that these factors cannot be found when looking at the white population. This leads to the notion that â€Å"‘Canadians’ do not break the law, but racialized ‘immigrant groups do’† (Chan and Mirchandani, 2002, pp. 9). The portrayal of minority groups and immigrants in the film can be seen when no white individual is shown to be a criminal. The members of the street gangs were of Latino, Black and Asian descents. The white characters portrayed were successful businessmen, a hero and a priest. In fact, the protagonist was a Korean War veteran where he killed several men in battle. Instead of being convicted for his actions, he was provided a medal of honor. The portrayal of these scenes shows that white individuals do not commit crime and so cannot be identified as criminals. Society had classified certain inviduals to be part of the Asian and Black race dividing them from the white population. Throughout various events and social processes the perception of Asian and Black race to be dangerous was constructed. This in turn had let these groups to be viewed as criminals. This is believed to be taken a significant effect due to unfair treatment and portrayal of minorities and immigrant in the criminal justice system. White as ‘powerful’ The notion of race as a social process has caused an effect where certain groups are marginalized. Within the society, a white individual is the dominant and superior while others are oppressed, and inferior. This perception has led to the view of that the white population is powerful compared to the other racial groups. The portrayal of this can be seen with the protagonist of the film. Thao and the other gang members had gone to his house to attack him. During the fight, Walt comes out pointing a rifle towards the gang threatening them to get off his lawn and leave. By doing this, he earns the respect of Thao’s family and the Hmong community. To show their gratitude, they showered him with gifts, meals and flowers. Through the remainder of the movie, Walt was shown to be a leader, influencer and hero. He was guiding Thao away from becoming a gang member by providing a job, teaching about manhood and purchasing items for him. He was also shown as a savior when he gave up his life so that Thao and his family can live a life without any gang violence. Within the racial context, the representation of Walt as the savior illustrates the ideology that white is powerful, whereas the Asian group is seen to be helpless, powerless and vulnerable. This leads back to the notion of social constructionism where the division of race had caused some groups to be in power and the others as powerless. In this case, the white group is seen to be of dominance while the Asian group is perceived to be inferior and vulnerable. Conclusion A once popular belief in society was that everyone was born into distinctive biologically and natural based differences known as race (Rothenberg, 2008, pp. 9). However as time passed, the notion of race had transformed into the idea that it was created through human interaction known as social construction. In other words, through social processes, the differences between racial groups were constructed and not from nature itself. However, through the development of division among groups, some were placed in a position of power while others in a minority position. Throughout time, the white group have become the dominant and powerful group over other racialized group. This, sequentially have led to several unfair treatment, marginalization, and oppression against this group. These effects have been portrayed in the film Gran Torino in regards to the racial group of the White and Asian. Through social constructionism, prejudices and stereotypical terms have been used to identify the Asians groups. Secondly, the notion of Asian youth as gang members. Thirdly, the perception of Asian individuals as criminals. Lastly, the ideology of white power over Asian groups. These reflections of currents societal beliefs and perception towards the White and Asian groups originated from the process of social construction. In other words, the reason why it the racial groups of Asians and White exist is through social collectivities . If society did not place a meaning towards the differentiation among individuals, race would not exist, thus these assumptions would be of non-existent as well. References Eastwood.
