Categories Of Carbon Steel Their Compositions Engineering Essay

‘STEEL ‘ is used for assorted metals of Fe. These vary from each other depending on the content and % of stuff added to the Fe base solution. On must maintain an of import factor in head, all steels contain a % degree of C + Manganese + Silicone + Sulpher. By increasing C to establish solution the stuff will increase strength and hardness therefore improves drastically the harden-ability. On the other manus C reduces the capableness of weld-ability and increases crispness. Several types of steels exist in our markets, the most common being ; field C, chromium steel, alloyed and tool steel. Carbon steel is one of the largely used steels in several industries. As explained antecedently, its belongingss are dependent largely on the % of C added but the other elements have minor influence excessively. One of import factor sing Plain Carbon Steel, is that this is a type of steel incorporating up to 1.5 % of C. One must foreground that most of the C add-ons in C steel are less than that of 1 % . Some applications of these steels are structural beams, auto frames, etc. ( Capudean, 2003 ) ( Iron Making & A ; Steel MAking, 2008 ) ( Jr. , 2007 ) Harmonizing to the ‘Steel Classification Society ‘ , Carbon steels are sub divided into four chief classs ; – Low Carbon Steels /Mild Steels ; these steels have less than 0.25 % of C, and these are the largely used class of C steels. Normally this type being unresponsive to heat interventions, intended to organize a martensitic construction, beef uping is achieved by cold working the portion due to low C content. These are really easy to organize steels with accomplishing popularity largely for not high strength applications. Some belongingss are ; Very tough, inexpensive sing costs ( least expensive to bring forth ) , they are easy machined ( more ductile than high C steels ) and welding belongingss are besides really good. Typically these have 275MPa – output strength, 450 – 550 MPa – tensile strength, and 25 % EL – Ductility. For such a ground, these are normally used in applications as Bridgess due its ability to deform under burden and return to its original. ( B ) ( Capudean, 2003 ) ( Groover, 2010 ) Degree centigrades: UsersNathanielDesktopRoadRailBridges.gif Medium Carbon Steels ; incorporate 0.25 % up to 0.55 % C. When it comes to belongingss, increasing C besides means a direct influential addition in hardness + tensile strength. On the other manus this besides effects severely the ductileness which makes it more hard to machine. Heat intervention to really thin subdivisions can better such machinability issues. These may be austinized by slaking and annealing afterwards to better such belongingss. These are comparatively stronger than the old class, whilst weaker than the high C steels. One common application of medium C steel is the production of crankshafts where high strength and stiffness is required to defy high tonss and opposition to tire when it comes to uninterrupted tortuosity and bending. Typical values are, 450-580MPa – output strength, 600-750 MPa – tensile strength, and 20-30 % EL – Ductility. ( Corus, 2010 ) ( Jr. , 2007 ) ( Iron Making & A ; Steel MAking, 2008 ) Degree centigrades: UsersNathanielDesktop1108phr-03+383ci-small-block-chevys+pistons-and-crankshaft.jpg High Carbon Steels ; incorporate 0.6 % up to 1.4 % of C. In a heat treated status it is able to defy high shear and wear hence, these are used in applications where stiffness and hardness play an of import portion such as in rope wire, besides good in prolonging crisp film editing borders. Unfortunately, these are the least malleable and really difficult to weld, in fact preheating and station warming ( commanding of chilling temperature ) is critical in order to obtain good welding sections and accomplish good mechanical belongingss. Since at their maximal hardenable conditions, these are the most brickle devising this a large drawback for this steel. ( B ) ( Jr. , 2007 ) ( Groover, 2010 ) Degree centigrades: UsersNathanielDesktopwire-rope2.jpg Very High Carbon Steel / Tool Steels ; are a ‘sub group ‘ of high C steels and contain lower limit of 0.8 % C. These have weak welding belongingss and ductileness, but are really good when it comes to strength, hardness and wear opposition that ‘s why it is really normally used in centre clouts. An of import factor for these sorts of steels is that most of them are used in a hard-boiled + tempered status. ( Jr. , 2007 ) ( Groover, 2010 ) Degree centigrades: UsersNathanielDesktop oolsteel.jpgP7: Question 2Select an industry and supply a brief over position of one metal forming technique used.The preciseness metal organizing procedure I will be discoursing is the Powder Formation ( PM ) . This gives an alternate cost effectual range towards stomping, hammering, machined parts and projecting. This is characterized one of the most enforced preciseness metal organizing technique in the modern industry and it is normally found in the automotive industry. Most vehicle parts presents are produced by such a procedure. PM combines pulverization compression with optimum physical belongingss with controlled high temperatures atmosphere sintering. ( Turkish PM ) Degree centigrades: UsersNathanielDesktopimage001.gif Such a procedure offers ideal benefits that you can non accomplish with using other metal working procedures. Mentioning merely a few, it is really material efficient since the finished portion uses 100 % of the stuff, whilst in other organizing techniques one will hold wastes. The procedure is really good in making intricate forms with minimum cost add-on. Some illustrations could be splines, cogwheels, away centric parts, etc ) . Sometimes this besides reduces assemblies since most of the assembly parts can be produced in a individual formation by PM. The PM clouts and rods produce parts with closer tolerances. A assortment of standard metals are specifically suited for PM processing, nevertheless intermixing can be easy done to run into specific belongings demand. Automatic rhythms make the PM procedure really labour efficient. The lone back draw is to put up the parametric quantities for the tooling, but as this is done, the procedure can bring forth parts at a really efficient r ate. High temperature Powder Metal ( HTPM ) , is able to accomplish 88-96 % of the material theoretical denseness. Since every stuff belongingss depends on denseness ( elongation, output strength, etc ) , HTMP outperform other procedures. ( GT.b, 2012 ) ( J, 2011 ) ( Marciniak, 1988 ) The high temperature metal pulverization procedure is divided into 4 chief sectors ; Blending – here high pureness metals pulverizations and additives are studied so funneled down to choose the optimal pick for the application in order to run into the coveted belongingss to the application. For illustration in the automotive industry, this procedure is used to organize panels. Here aluminum pulverization with anti oxidation additives and silicone for elastic belongingss are added in order to organize the ideal mixture for the door panel. All the pulverizations are assorted with particular lubricators which helps treating the pulverization flow. As mentioned before, blending the pulverizations in a solid province provides new chances to come up with new belongingss unique merely to HTPM. Compacting – Powdered metal is fed from a hopper into a provender shoe. The provender shoe delivers it into a die pit. Here multiple pulsations compress it into 50 % of its original capacity. Second strength packing forces realign and deform the atoms whilst implementing local mechanical bondings organizing a portion known as ‘a green portion ‘ . These are ejected carefully by automated machines and conveyed to the following measure. Compacting imperativenesss vary from 5 up to 900 tones and are capable of multiple gestures. Sintering – this involves puting the green portion in temperatures above 1300AÂ °C ( but below runing points ) . By such a procedure a batch of benefits are achieved, metallurgic bonding is enhanced, ductileness and stamina are besides improved. The initial art of the procedure cleans lubricators and surface of the metallic atoms to guarantee perfect mechanical belongingss sing the finished constituent. At the 2nd portion of this procedure ( go forthing portion in high temperatures ) , this allows energy to transform mechanical bonds to metallurgical bonds. Completing – sizing / coining are post operations that can be used for more complicated and minor tolerance dimensions, ( illustration – engine parts like cylinder valves, linking rods, etc ) . Extra coating assets could be milling, crunching etc. From here it can come on to a connection procedure. After joined this can besides be heat treated and plated. Heat intervention goes up to 550AÂ °C to do a bed of Fe3O4A which acts as corrosion resistant, and increase in hardness. ( N.A. ) ( GT.b, 2012 ) ( J, 2011 ) ( Marciniak, 1988 ) Note- A presentation will be held in category explicating the procedure in more item. Degree centigrades: UsersNathanielDesktopcycle.jpgP8: Question 3Distinguish between merger & A ; non merger, besides select one procedure and discuss. Finally supply one application and besides discuss.Welding is a procedure to bring forth high strength lasting articulations between two ( or more ) parts that need to be connected with each other by agencies of a weldment ( metallurgic fall ining subdivision ) . There are assorted ways to obtain such a connexion and with today ‘s engineering we are accomplishing better belongings results when it comes to post welding belongingss. Chiefly the procedure involves heating a portion, runing the portion / base metal ( depending on which procedure is adopted ) and connection of the stuff occurs as temp start to chill down. Thus the procedure required relies chiefly on the application of heat and force per unit area. One common welding factor is that the metallurgic construction of any metal will be changed station to welding. This coul d take to a station welding heat intervention procedure. ( T, 2010 ) ( Key to metals, 2007 ) Welding is divided into two chief groups, depending on the physical province of the base metal during the procedure that of the base metal being in liquid province or in solid province. These procedures are better known as merger and non merger welding techniques. In order to choose which welding procedure demands to be selected one should first analyze both the welding procedures and addition information sing pre dyer's rockets and station dyer's rockets. ( YAÂ ±lmaz, 2007 ) Fusion / Liquid State Welding ; this is the most common type of welding found in the industry due that the dyer's rocket produced is really strong. In this sort of fall ining procedure, the base metal is melted in order for the dyer's rocket to happen. Apart from the heat beginning a filler stuff ( consumable electrode ) may be fed besides into the welding pool. This procedure may besides utilize a protective bed between our environing atmosphere and the liquefied metal ( gas shield or flux ) . This protection consequences in a scoria on top of the welded seam which subsequently on solidifies and can be removed. There is a assortment of merger welding processes that can be used holding a different belongings result. ( Marinov ) Three major classs of merger welding are found which are bomber divided into different procedures ; Arc Welding: in this sort of procedure warming and thaw of the stuff is done by an electric discharge. Some illustrations of discharge welding could be ; Shield metal discharge welding, , Gas tungsten arc welding, Plasma discharge welding, Gas metal discharge welding, Flux cored arc welding, Submerged discharge welding, Electroslag welding. Gas Welding ; for this sort of welding the gas produces a fire that melts the basal stuff. An illustration of such procedure is ; Oxyacetylene welding High energy beam welding ; here a high energy beam is shot between the two parts held together under force per unit area. As the temperature starts diminishing after the beam Michigan, the parts start to bond together. Some illustrations of this procedure are ; Electro beam welding & A ; Laser beam welding. Basically all the procedures reference antecedently for merger has the same principals. A heat / energy beginning is concentrated on a really little country and a weld pool is produced. These heat beginnings for merger are arc, high energy beams and gas. Obviously the power denseness rises from gas fire to an electric discharge to a high energy beam. For the classs mentioned below we can analyze a graph demoing the heat input to the work piece vs power denseness of heat beginning. It is reasonably obvious that as the power of the heat beginning additions, the heat input to the welded portion decreases. Therefore the less the power denseness of the beginning the larger the affected country. Excessive clip for heating can do harm to the work piece, by changing the belongingss including deformation and weakening. ( Schwartz, 1979 ) Degree centigrades: UsersNathanielDesktopUntitledff.png Therefore one of the advantages on power denseness increaser is deeper incursions, optimum welding qualities, and less exposure clip for the welded portion. This procedure is besides various, and adaptable for confined infinites. On the other manus some disadvantages are, it is non every bit productive as uninterrupted wire applications, current bounds are critical to find the joint potency. ( Liverpool, 2000 ) Non Fusion / Solid State Welds ; for this type of welding heat is applied merely for the base metal to soften in its solid province in order to ease fictile distortion or rush up the solid province diffusion. As the name provinces, in non merger welding the stuffs are joined together without the demand of runing the base metal. Here the stuffs to be joined are brought together at equilibrium spacing for fictile distortion through high temperatures ( below runing point ) and force per unit areas. Some of the chief non merger welding techniques are ; Cold welding: In this procedure the dyer's rocket is achieved by the force per unit area and little lift in temperature due to cold working. Some typical illustrations are ; Press welding & A ; Roll Welding. Clash welding: For this procedure the dyer's rocket is achieved due to the heat produced due to using force per unit area between the parts i.e making clash. Some illustrations are ; Radial Friction welding & A ; Orbital Friction Welding. Diffusion Welding: here both parts are held together under changeless force per unit area, promoting the temperature somewhat and left invariable for a peculiar clip frame ( depending on the stuff ) . Some illustrations are ; Conventional Diffusion welding & A ; Deformation Diffusion welding Solid State Deposition Welding: Chemical reaction bounding. Degree centigrades: UsersNathanielDesktopspwmtfeb2001f1.jpg The first advantage of such a procedure is that low heat is required, hence minimum disruptors in crystalline construction are noticed since no thaw temperatures are required. This could besides be applied for stuffs within the same category or even within different categories due that no intermixing is involved. The chief disadvantage is that for such a procedure big, fixed machineries are required and this is a consequence for big capital financess to purchase the equipment required. Another disadvantage is that this procedure is non really feasible to be applied for little graduated table applications since its complicity. ( Jr, 2004 ) ( Lancaster, 1999 ) Describing one peculiar welding method, the method I will be discoursing is the ‘Hyperbaric Welding Process ‘ normally known as under H2O welding. This procedure falls under the class of Fusion welding. This is a really good illustration of welding in an unusual, critical environment. For such a procedure the welder must be an A class welder plus a commercial frogman in order to defy the harsh and unsafe sea conditions nature has to offer. ( Mukund, 1974 ) Degree centigrades: UsersNathanielDesktop2071602_f520.jpg In order to delegate instantly the procedure with an application mentioning advantages, disadvantages, equipment, restrictions and safeguards, the underwater welding is a procedure used in the offshore industry. The offshore industry covers the fixs of vass ( any kind ) , boring platforms ( jack up rigs, semi submergible rigs, self propelled rigs ) , Bridgess, etc. These constructions face terrible conditions conditions and are invariably flexing in multi conditional environments, hence the hazard of harm and failure is far greater. Basically this sort of welding is ideal and it is really flexible since the work could be done under the water line, therefore the natation works could be repaired in place without the demand of docking the platform to obtain dry conditions. This consequences in less sweeps and loss of valuable boring clip. Restrictions of such a procedure for our boring platform application are that the system is necessarily bulky and expensive to run. For such an application normally low to intercede C steels are used. Steels are designed as CT and a figure after to demo the C content. The most common steel found in this industry is CT3. Low and intermediate C steels are ideal since these have high malleability and sensible dyer's rocket ability. A The weld ability of depends on their C + manganese content in concurrence with their dross degrees. At low C degrees that of less than 0.15 % , the steels are non difficult and the dyer's rocket ability is excellent.A For the medium C type, 0.30 – 0.60 % C is found and these can be welded easy by agencies of discharge welding. Unlike the surface normal discharge welding, where such intermediate C have higher hardness and martinsite formation, in dry conditions pre warming and station warming are required. For deep sea dyer's rockets alternatively of pre warming and station warming, the dyer's rocket is non performed at one spell but with intermediate intermissions. ( Martikainen ) ( Sacrificial Metal, 2012 ) Degree centigrades: UsersNathanielDesktopcorrosion_drill ( 1 ) .jpg Basically there are two categorizations to execute submerged welding. The choice of the proper method is selected after an submerged structural / hull study and the parametric quantities of the submerged environment. The welding categorizations are ‘Dry Welding ‘ & As ; ‘Wet welding ‘ . Wet Welding ; here the welding is performed to the direct exposure of the wet conditions. Here the ‘Manual Metal Arc ‘ procedure is used. The principals of such a procedure are fundamentally the same as that of Arc Welding on dry land but in this instance a particular H2O cogent evidence electrode is required in order to protect the electrode ‘s nucleus. This is the most efficient and cost effectual welding method found amongst all under H2O welding. For this method the power supply is located on the surface of the H2O ( dry conditions ) and the overseas telegrams and hosieries are fed to the frogman via overseas telegram defenders ( big flexible piping ) . The power supply provenders direct current ( DC ) 300 – 400 As through overseas telegrams with negative mutual opposition. If positive mutual opposition is used in DC electrolysis will occour and causes rapid impairment of the metallic constituents in the electrode manus held holder. DC currents are used alternatively of AC ( Alternating ) due to electrical safety and the trouble of keeping the discharge in wet conditions. Motor generator welding machines are normally used. For the moisture type welding it is of import that the circuit includes a knife switch ( Positive type ) . This sort of switch is operated on the surface but eventually commanded by the frogman for optimal safety. This switch should be capable of interrupting the full welding current and stops the dyer's rocket ax the switch is non-operated. As mentioned antecedently, even the electrode itself should hold a particular coating of waterproofing. Basically all connexions should be insulated in order that no H2 O comes in contact with any metal parts. If this insularity is damaged, current will leak and will non be available in the discharge. ( Levi, 2010 ) This method is low cost compared to dry welding, it is besides an onsite occupation i.e. no demand of complex equipment an the frogman can make places of the offshore construction that could non be reached by other types of welding. Some disadvantages are that there is an immediate quench of the welded articulation due to environing Waterss ( additions tensile strength – decreases ductileness & A ; increasure in porousness and hardness ) .large sums of H is present taking to disruptions. H2 dissolves in heat affectional zone and the welded articulation could check. The chief disadvantage is the safety issue sing visibleness and currents Degree centigrades: UsersNathanielDesktopWelding.Programs.jpg Hyperbaric Dry Welding ; here the dyer's rocket is done in a certain chamber. This chamber is normally filled up with He incorporating 0.5 saloon of O at positive force per unit area somewhat above ambient. These dyer's rockets are somewhat higher in quality that of moisture welding and run into X-ray cryptography demands. For such a procedure the ‘Manual Metal Arc ‘ is used or the ‘Gas Tungsten Arc ‘ welding is used ( depending on the welder accomplishments ) . The welding is done in dry conditions but at hydrostatic force per unit areas of the deepness of the environing sea. For the dry dyer's rocket procedure the welding power generator could be AC and DC. Degree centigrades: UsersNathanielDesktopCommercialDryBell.jpg Some advantages of dry welding are that the frogman is safer since the dyer's rocket is performed in an enclosed chamber, hence no direct distractions from currents, and visibleness is much better than moisture welding since the chamber is illuminated. Good quality dyer's rockets are achieved comparable to come up welding and H2 degrees are much lower than H2O dyer's rockets, not distructave proving could be performed in the chamber. Some disadvantages are that the procedure requires much more capital and support at the surface as the method is much more complex, the cost additions with deepness, and the procedure is non every bit flexible as the unfastened H2O dyer's rocket as the connection subdivisions should suit the enclosed chamber. ( Akers, 2012 ) To depict the procedure of Manual Arc Welding, the work that is traveling to be welded should be straight connected to the positive side of the electric circuit via overseas telegrams. Sometimes the Earth overseas telegram incorporates more than 1 connexion in order to obtain the best circuit continuity for the land. A flux ( plus H2O proofing ) electrode is connected to the manus held holder via another overseas telegram which are connected to a power welding coevals beginning. When the tip of the electrode touches the work piece, the current discharge from the spread and causes a flicker which melts the base metal and the electrode organizing a dyer's rocket puddle. Degree centigrades: UsersNathanielDesktopwelding-circuit.gif Comparing both diagrams we can detect some differences. For the moisture procedure, DC current, a knife switch and dual insularity overseas telegrams are required. The mutual opposition is -ve, whilst the circuit is fundamentally the same. As the discharge is moved off from the work piece, the pool solidifies and the articulations are fused together. This welding pool is controlled by changing the current which flows through the discharge being produced and by altering the electrode diameters. Typical temperatures are those of 5000Â °C. by such a procedure a consequence of metallurgical bonding is achieved through the work piece. At these elevated temperatures, metals are ‘active ‘ and if it comes in contact with air it rusts immediately and the mechanical belongingss of the joint fail. For such a ground the discharge welding provides agencies of screening to the dyer's rocket pool ( gas, scoria ) . This is known as metallic discharge shield and is accomplished by the flux covering the electrode nucleus. The scoria produced as the pool cools and solidifies has its map to minimise contact of dyer's rocket to air until temp lessenings. The discharge creates a little pit formed inside the flux. This is for the flux to fire slower than the metal barrel i.e. helping in the protection and control of the metal sedimentation that leave the electrode. For the welding procedure this is a critical in order to keep a changeless discharge and weld articulation. Even in hapless under H2O visibleness, the frogman needs to maintain force per unit area on the electrode to keep a changeless good provender rate. In under H2O welding in is really of import to advert that the discharge behaves otherwise than it does in air. In H2O gas bubbles are a really of import factor as these create an unstable discharge for good welding conditions. In concurrence with this, it is much more hard to command the dyer's rocket puddle. The frogman must put currents by test and mistake depending on the Waterss conditions ( temp, salt, etc ) . Apart from this there is no difference between surface and under H2O welding. ( Kaets, 2000 ) Degree centigrades: UsersNathanielDesktopshielding-weld-arc.gif When compared to other welding procedures Manual discharge welding is normally used because the equipment is comparatively easy to utilize and inexpensive ( compared to other types ) , it is flexible, portable, and ideal for the frogman to utilize in confined infinites, no gas shield is required and eventually it is suited for about all sort of metals and metals. Some disadvantages of discharge welding are that the electrode needs to be replaced often ( more exposed to daze ) , the scoria should be removed after the dyer's rocket is performed, and the procedure is somewhat slower since the rate of deposition is slower than continuously fed electrode procedure ( Gas Tungsten Arc ) . ( Kaets, 2000 ) One last note sing under H2O welding ; there is a procedure non normally used which features a specially built keeping torch which sprays a changeless cone made of high force per unit area H2O, with protective gas under force per unit area to insulate the welded are from the H2O during the dyer's rocket is performed. Besides a recent development was done affecting under H2O optical maser beam welding. This method is still being improved but will shortly be applicable for the offshore industry. ( Clutter, 2012 )

British Satellite Broadcasting: the Beginning of the End

Entrepreneur Research Paper Adriel McBride DeVry University December 17, 2012 TABLE OF CONTENTS Introduction 3 Abstract 3 History behind BSB 4Reasons for Failure 5 Analysis 7 Works Cited 10 British Satellite Broadcasting: The beginning of the end IntroductionMany companies fail within the first two years of opening, according to small business administration which is seven out of ten, and 51 percent last at least five years. Starting a business is not an easy task, there are tons of things that have to done in order for it to be around for more than a couple of months or years. Unfortunately, that’s the case with the company I chose, British Satellite Broadcasting. Abstract British Satellite Broadcasting (BSB) set out to establish a television company that provided direct airing to television services from a satellite to the United Kingdom.Which it did from 1977-1990 and had its first broadcast on March 25, 1990, most of the time was used towards creating a policy to hav e British be able to broadcast via satellite (Holden, 1998). The company had to merge with Sky Television in November of 1990 to form the British Sky Broadcasting (BSkyB’s). History behind BSB In 1977 the development of British satellite broadcasting policy started, a meeting was held at the World Administration Radio Conference for a hearing for the division of broadcasting frequencies.During the meeting the administration assigned each country five high-powered channels for direct broadcast by satellite for domestic use. In 1982 BSB was awarded with two channels through the British Broadcasting Corporation (BBC) and in 1983 it started to negotiate with the Independent Broadcasting Authority (IBA) to join a joint-venture with other countries and start a joint satellite service but failed in 1985 (Holden, 1998). It was said that the government insisted that the BBC should pay for the cost of constructing and launching a dedicated satellite. The hearing concluding in 1992, whi ch followed the Conservative Party’s fourth consecutive election victory and BSkyB’s successful, momentous bid for the rights to screen live English Premier League football matches† (Holden, 1998). The BSB had one main competitor which was Sky broadcasting, it had an advantage over BSB and proved that its system gave sufficient picture quality and many viewers didn’t want to wait on a promise that was vowed by BSB for excellent programming. Many customers compared the competition between the rival satellite companies to the format war between VHS and Betamax home video recorders and chose to wait and see which company would win outright as opposed to buying potentially outdated equipment† (Holden, 1998). BSB mission was to create a satellite dish to broadcast high quality television programming for the British and hopefully expand to other countries. The reason BSB failed can be related to a lot of things but mostly money. Before BSB and Sky merged, Sky debuted first which hurt BSB, Sky provide a cheaper dish, which made it even more difficult for BSB.In January 1989 BSB experienced higher than expected cost that were required to achieve their planned air date. That caused them to push back their fall launch date. This resulted in delays for developing a new semiconductor chip required for its satellite dish receivers, which raised their cost to ? 131 million (Holden, 1998). Many say that if BSB would have launched first they could possibly still be around. Sky and BSB were in financial trouble and after BSB collapsed in November 1990, they were forced to merge.That is how the BSkyB came about, no more BSB it was over and a new company had begun which was marketed as Sky TV. Reasons for Failure British Satellite Broadcast failed for a number of reasons one was the lack of financial stability and commitment. BSB was spending millions of dollars on equipment for receivers so they can be available for purchase. But they were slack ing in the production department because they needed more money to make sure they had quality programming but missed their deadline. By the time they finally launched people had already turned to the competition because they were tired of waiting.When a promise is made to consumers it’s best for the company to do everything in their power to oblige them or otherwise they will lose their support and money. That’s exactly what happened with BSB they were focused on quality which was great but couldn’t provide it in a timely matter. Their competition offered a cheaper product and adequate quality which was better than nothing. The merge only helped Sky stay alive and killed BSB because they took all of BSB quality equipment and satellites and created something great.But if BSB would have kept their commitment/ launch date it could have been a different outcome today. So it kind of boils down to customer satisfaction, which is always a big part of a business success . When BSB couldn’t make good on their promise it reflected badly on the company and made their consumers wonder if they were really up for the challenge. For example take a gamer that is anxiously waiting for a new Xbox game console to come out and is schedule for release in May but is pushed back to August, a lot of loyal customers will be let down and possibly turn to PlayStation which new console came out when vowed.They may not lose a lot of of customers but it could cause a ripple effect for the ones that did chose to get a PlayStation instead. That is what happened with BSB, they had satisfied customers when they finally launched but not enough to keep them in business. Another thing that caused them to fail was not having the sufficient operating funds. The owners didn’t estimate how much money they would need to accomplish what they set out to do. It is always important to know how much money your business will necessitate, that includes the starting cost and staying a business.That was not well executed when the owners of BSB started the company which was a major cause of why it failed. Too much money being put into the company but not enough coming in. They had major financial issues they caused them to basically turn over their business to their competitor. That is never how an entrepreneur plans their business to turn out especially a few years after starting. While a lot of people were still happy with the 5 channels that they had globally, a lot of people were also tired of having only 5 possible things to watch and so they got Sky as soon as it was available.As it turned out, hundreds of thousands of people got Sky before BSB even launched (William, 2011). Most of the people who were interested in having a greater choice of channels had already opted for Sky. There was hardly anyone who still wanted a DBS system left for BSB to sell their service to. As a result, BSB launched with only a few hundred systems installed, and never re ally increased beyond that. The real cause of their failure can probably be laid at the door of the IBA.While they never intended for BSB to fail, they locked BSB into a contract to build and launch satellites, implement new picture systems which were not standard in the UK (and still aren't today) and do other things which Sky were not required to do (Holden, 1998). This resulted in severe hold ups which allowed Sky to eat up almost all of the market that BSB was aimed at. While BSB were busy launching satellites and awaiting delivery of MAC equipment, Sky had launched and was building up a growing customer base (Holden, 1998).Analysis BSB could still be around if it wasn’t for the IBA contract and making unrealistic goals. If BSB would have started out with a less expensive product they could probably still be in business. They wanted too much too fast, the best quality and products that cost some big bucks that they did not have. Therefore it hurt them, a better plan and t eam would have set them above the rest. Better planning in general could have prevented the business from failing. They could have cut out every unnecessary expense and reduce the expenses. Became a saver with cash and collect every dime owed to them.Finally they could have started selling their products and service at a discounted price until they built up a loyal customer base. If the entrepreneur would have recognized the company was failing before it was too late, he could have taken actions to turn around the business. The business owners and leaders should have taken every action necessary to first preserve their own interests and salvage/protect personal assets associated with the company. Protecting the business assets is critical for survival of any company. The idea of satellite broadcasting was great but not well implemented nor calculated.BSB wanted to give customers better than what they were receiving from the competitor but didn’t go about it the right way. The y started off spending way too much money and still coming up short. When developing a new product it takes lots of inputs such as money, skills, energy etc. that is supposed to add value to their product output (Hatten, 2009). The four major functions of managing a business is planning, organizing, leading, and controlling (Hatten, 2009). Within those four boundaries BSB went wrong with at least three which were planning, organizing, and leading.I didn’t choose controlling because they really had no control of their project because of the IBA. If they would have never signed the contract with IBA and stayed with the BBC things could have turned out differently. IBA demanded services that BSB just couldn’t provide. Even with that being the case, if the entrepreneur was better at leading he could have had a strategic plan to keep his company alive while pleasing the IBA as well. That could have been done by trying to develop one of the requirements at a time. The best t hing to do would have been to get working satellite receivers on the market.Then see how well they do by getting feedback from the consumers and find out what could be done to improve the service and products. After they obtained enough information on what was wrong with the â€Å"prototypes† that was first released they could start improving the devices and making it available for sale and send an upgrade device to the customers that already had a receiver. Sometimes it’s about taking a chance with a bad product versus failing as company altogether and putting out a few bad receivers. There are tons of companies that started off horribly but still made a profit and are now at the top.For instance Sprint Wireless, everyone including myself hated their phones and service back in the 1990’s but now in 2012 they are one of the top cellphone providers. They accomplished that by staying afloat during the rough patches and critiquing there services and products. BSB s imply wanted to be the best and provide excellent programming and quality but didn’t plan accordingly. Having a great plan and knowing how to execute it can be what makes a business succeed. BSB had a great plan but just couldn’t meet the expectations.Sometimes less is more, if they would have started a little smaller and worked its way up I believe Britain’s would be watching British Satellite Broadcasting instead of Sky TV.

CoupContrecoup Injury Essay Example | Topics and Well Written Essays - 2750 words

CoupContrecoup Injury - Essay Example In this clinical review paper, the clinical concepts from the latest literature will be synthesized about this type of injury, its incidence, physiology, pathophysiology, clinical manifestations, diagnostic methods used in the practice, and implications on the advanced nurse practice management. Basically coup/contrecoup arises from contusive injury to the brain when both the impact of direct trauma and trauma due to movement of the brain within the skull leading to impact on the opposite site are responsible. However, the clinical signs and symptoms and as a result, the management would depend on the degree of the trauma and the extent of the injury. Nurses, while planning a care of such patients must be aware of the advancements in management, and a clinical update based on review of the researches is therefore necessary. In this article, the findings have been presented in a concise manner. The problem of head injury is enormous. In the United States, it accounts for fatalities, disabilities, and morbidities of great numbers each year. Moreover, many multitruama victims also have associated head injuries. This occurs predominantly among young adult males aged 15 to 35 and quite frequently is associated with motor vehicle accident and alcohol use. In these patients, especially when it is associated with multiple traumas, the presence of head injury can be caused by trauma, direct or indirect. From the care point of view, this represents both surgical and medical challenges. Essential to the survival is a rapid and systematic approach to management that incorporates simultaneous assessment and resuscitation. Coup/contrecoup injury is the result of contusive brain injuries that occur with blunt trauma, in which the skull is not penetrated. It is to be remembered that anatomically brain literally floats in the cerebrospinal fluid, and therefore, any mechanical impact, eith er from falls, automobile accidents, assaults and violence, physical abuse, or recreation-related accidents, can cause the brain to move within the skull, resulting in focal, diffuse, or generalized injury. In fact any time, the head is subjected to violent force or motion, the soft and floating brain is slammed against the skull's uneven interior. In a coup/contrecoup injury, a moving object strikes the head, denting the skull inward and also knocking the brain against the opposite side of the skull. Thus, this can result into bruising in two places within the brain, at the site of the original point of contact and on the opposite side, where the brain struck the skull. These are included in the category of mild traumatic brain injury, where the neural damage may occur without involvement of the skull or the membranes, since there is considerable shear that can involve the neurons on the opposite side. This is a form of direct contact force mild traumatic brain injury resulting int o observable tissue damage in a particular area of the brain. The additional bruising on the opposite side may account for other associated symptoms such as personality changes, perceptual or sensory problems, difficulty expressing, and balance or motor difficulties. Incidence Epidemiologic data regarding coup/contrecoup injury is difficult to obtain due to inconsistencies in definition and classification. Moreover, many patients with

Gender and language in ELT materials Essay Example | Topics and Well Written Essays - 2000 words

Gender and language in ELT materials - Essay Example emic and social discourses around the world for several decades now. Gender issues such as equality have taken centre stage in the world today, and many efforts are being directed at eliminating all forms of discrimination against women; gender equality has now been acknowledged as a universal human right and was articulated as the third millennium goal of the Millennium Summit in 2000 (Deirdre and Maryann 2008, p.303). Education reflects the global efforts by addressing issues such as gender equality and inequality in society; however, there could be worrisome possibilities that education of women, men, girls and boys, has been compromised in the past because of both explicit and implicit gender bias. In this respect, gender bias and language in the English Language Teaching materials have been major areas of focus in the current practice, in an effort to crackdown on any forms of gender bias against the women in society. This paper aims at examining gender and language in ELT mater ials in the current practice, to highlight, among other things, the new understandings of gender inherent in the ELT materials, in addition to the language specifics of ELT materials. Gender biasness in ELT materials can be explained by the ambivalent sexism theory because they depict both hostile sexism -denoting an active antagonistic view of women that, both explicitly negative and restrictive, and benevolent sexism-beliefs that women should be cherished, adored and protected from harm (Mehta et al 2013, p.38). As far as benevolent sexism is explicitly positive, it restricts women by viewing them stereotypically and in limited low-status roles, thus is just as potentially damaging as hostile sexism. Ambivalent sexism is built on three major aspects namely dominant/protective paternalism, gender differentiation and, heterosexuality; dominant paternalism/competitive or heterosexual hostility and gender differentiation are elements of hostile sexism whereas protective paternalism is an element of benevolent sexism. Dominant paternalism is the mechanism through which attributes thought to be suitable for positions of power and structural control are assigned to men whereas protective paternalism is the idea that women are ‘weaker sex’ that should be protected and cherished. Heterosexual hostility is the belief that women use their sexuality to control men; competitive gender differentiation refers to the belief that men are the only sex with characteristics such as ambition and agency, which are essential for positions of power and high status. It is no doubt that language is a very powerful tool of socialization that often times shapes the social constructions of gender in many societies across the world today; for decades now, studies have been concerned with the social justice issues. One of the predominant themes of these investigations has always been the role of language in the location and maintenance of women in disadvantageous position in society (Corson 1992, p.230). It has been established repeatedly that education plays a major role in creating unjust

Business of Fashion COS shopping mystery Essay Example | Topics and Well Written Essays - 500 words

Business of Fashion COS shopping mystery - Essay Example The essay "Business of Fashion COS shopping mystery" concerns Business and Fashion. The objective of establishing COS was therefore to provide people like these with the opportunity to purchase classy and fashionable goods without necessarily paying exorbitant amounts of money. On the other hand, it is also important to note that offering cheap products was not part of this strategy; the goods were supposed to be cheaper but not cheap. Finally, after months of talking about it, I visited the COS Flagship Store at 222 Regent St – near Oxford Circus. I must say that the store had a very good ambience, and the setting gave it a grandeur that I did not expect to see given the â€Å"cheaper† slogan that H&M had adopted for use in selling COS to its customers. The store was generally clean, and the dressing rooms were nice, presentable and welcoming. The attendants were all dressed in casual clothing, which was not a surprise considering the line of work they were in. From th e entrance, I could see both classic and casual attire. It is also worth mentioning that all the employees wore the current season trends from the brand; this is a promotional strategy that is used by businesses all over the world. If you want to popularize your products and get people to use them, start closer to home. One thing that left me disappointed during my visit was the service. I mean, it is one thing to set up shop, and a different thing to create good customer service that promotes a good rapport between a business and its customers.

Over education in the graduate labour market Coursework

Over education in the graduate labour market - Coursework Example The qualification has not been much a factor into determining the amount of wages one is to get from working. In seeking for reasons to back the claims, most researchers have found out that the phenomenon is pegged on the fact that there is difference in ability between those who leave higher education above others (SILLES, Peter Dolton and Mary, 2001). In addition, the perception and reception of higher education has changed leading many people to join and pursue education. Career relation of most courses result in mismatches and as the search for jobs intensifies, higher education becomes the differing factor hence the presence of overqualified members in jobs they take. The economist published an article that portrayed the over 40,000 degree courses offered across the UK universities as at 2002. Moreover, Chevalier (2000) noted that the education tuition fee has come down a great deal and many people are resorting to better themselves with the view of obtaining better jobs and take home packages. Eyebrows were raised when an author Hutt claimed that there is great waste that results from personnel that work in wrong jobs than those that are unemployed (CHEVALIER, Arnaud, 2000). In their article, Dolton and Vignoles (2002) came up with a revelation that estimated 30% of the UK graduates to be more educated than job requirement and availability in the UK markets. 22% have jobs that do not require them to have degrees while six years down the line they find themselves highly educated than their job demands (CHEVALIER, Arnaud, 2000). Studies reveal a majority of reasons into why people are more educated than they are required in their job requirements. The phenomenon has been shaped by the labor market structures, public sector culture, nature of work (part-time and temporary), family commitment, health conditions, debt incurred during study time, early market choices, business-cycle

Do Moral Rights Adequately Protect the Author's Work against a Research Proposal

Do Moral Rights Adequately Protect the Author's Work against a Derogatory Treatment - Research Proposal Example It is important to address this issue, in order to arrive at some recommendations on how statutory limitations can be improved such that the integrity of original works is not compromised, especially within a digital environment. This research proposal, therefore, poses the question: â€Å"Do moral rights adequately protect the author’s work against a derogatory treatment?† This research proposal examines existing statutes to find out whether they provide adequate protection for an author’s moral rights. The preservation of these rights, which are the personal rights of the author, is vital to ensure that creators of original works of value and merit are not discouraged in their creative pursuits by the distortion of their works through the production of derogatory adaptations of their work. In order to adequately address the research question, this proposal includes an examination of case law and how the courts have addressed the issue of moral rights. Some comparisons are also made with international laws. Based upon the literature review and case law, it appears that UK statutory provisions are inadequate to protect an author’s moral rights and enhanced protection for moral rights is necessary, especially in a digital environment. The Copyrights, Designs and Patents Act of 1988 was framed to protect the rights of an author or original creator of a creative work.1 The CDPA protects copyright and rights of authors/creators for original work where there is a high level of human skill and labor that is involved in the production of the work2, with the objective of ensuring that the creator is rewarded for his innovative efforts and hard labor by acquiring the exclusive right to economic exploitation of his work.  

Google Earth Essay Example | Topics and Well Written Essays - 1000 words

Google Earth - Essay Example ese stars were created as a result of collisions of Andromeda with other galaxies or collisions within itself or even destroyed another galaxy during collision whose stars are now strewn in the Halo. (Savage, Villard and Brown). The Owl nebula is a planetary nebula formed by a dying sun-like star. It is located about 2600 light years away in the Ursa Major constellation. Planetary nebulae like the Owl nebula now bear no relation to creation of planetary systems as previously believed. These dying stars, unlike bigger stars, are unable to generate energy through fusion of helium into carbon once their hydrogen fuel has burnt out. As a result their core turns into a â€Å"white dwarf† and only radiates the energy resulting from its collapse. The outer layer is pushed outwards and is energized by ionization by the core. However, such nebulae are short lived and cool down after approximately 10,000 years. The picture of Owl nebula in this version of Google Earth looks like a blue spherical shape with green clouds at its periphery. However, upon searching elsewhere, other pictures were found which, when used with certain filters, show two large eyes similar to an owl’s inside the nebula. A sample is given below. The first Messier Object recorded in Charles Messier’s catalog, M1 or the Crab Nebula, is a supernova remnant that is said to be expanding at 1500 kilometers per second. At its centre, spinning thirty times per second, there is a â€Å"pulsar† which sends out strong gamma and radio waves. The orange outer filaments are composed of hydrogen and are the remains of the star. The inner blue glow is created by electron clouds rotating in the magnetic fields created by the pulsar. (Hester et al). The Whirlpool Galaxy is one of the brightest galaxies visible using amateur telescopes or binoculars. It is a spiral galaxy conspicuous by its two large spiral arms. Scientists believe the formation of these spirals and the birth of stars within them are related to

Ethics Assignment Example | Topics and Well Written Essays - 750 words

Ethics - Assignment Example Inevitably, these factors embrace life-sustaining therapies. (Helm, 1984: 755) The same is applied in the cases under study: Assignment 1: The contemporary world has witnessed the attack of new and fatal diseases, which has forced the medical scientists to devise medicines in order to combat with such diseases. These include HPV, HIV, hepatitis and others. HPV (human papillomavirus) is, like HIV, a contagious disease and is common all over the world. However, its treatment is extremely expensive. Since the infection spreads due to extra marital sexual relationships and sexual intercourse, the deontological ethical code condemns it and lays stress upon the observing of moral values for the prevention of sexual diseases. Hence, it views high price of the remedy and treatment for sexually contagious diseases. It is therefore it does not look for the decrease in the price of such medicines. However, utilitarian school of thought vehemently supports such acts and behavior that provide gra tification to individuals provided it does not harm or hurt the others. Hence, utilitarians are of the opinion that the remedy for sexually transmitted diseases must also be economical and easily available. Hence, there are two schools of thoughts that lay influence upon the promotion of government interventions in social, cultural and health conditions. These are Evangelicals (or deontological) and the Utilitarians. Utilitarianism is sociological school of thought where works and ideas of renowned political scientist and lawyer Jeremy Bentham maintain lion’s share. The idea looks for the concept of the greatest happiness of the greatest number of people. Renowned English theorist J.S. Mill also serves as the arch-supporter of utilitarian school of thought and is of the opinion that every man’s act must provide maximum pleasures for the others. And if an act is not damaging the interests of others, the society should not create impediments on the way to seeking pleasur e. He stands for the qualitative separation of happiness and considers moral and intellectual pleasure superior to physical pleasures. â€Å"The greatest happiness principle has had a large share in forming the moral doctrines even of those who even more scornfully reject its authority.† (Mill, 1863:8) Hence, utilitarian approach looks for reducing the cost for the treatment of HPV, to make it affordable as the medicines for HIV treatment are economical and affordable. Since society must be healthy and fit, it should be allowed to get into pleasure seeking activities provided they are not harming the other members of society. On the contrary, deontological school of thought is of the view that the infectious diseases including HPV, HIV and others are transmitting the fatal disease to others; they are putting the life of others in grave jeopardy. Hence, if people are aware of the high price of the medicine, they would start avoiding the sexual activity without using contracept ion including condoms, loops and others. Assignment 2: Since Howard has arrived at the clinic for treatment, he must be provided with the adequate medical advice. Consequently, the nurse should certainly

Final Writing Assignment Essay Example | Topics and Well Written Essays - 500 words

Final Writing Assignment - Essay Example The statement is so true as evidenced by the breach of terrorists over the American airspace undetected and resulted to the destruction of the Twin Towers of the World Trade Center, an institutional landmark of the country, that killed thousands of innocent people. Scheuer stated that Bin Laden believes that the foreign policy of American is an attack on Islam. Bin Laden, through his Al Qaeda group was pinpointed to be responsible for the 9/11 attack – precisely the group that was being governed by Scheuer. Scheuer’s remarks are disturbing as they are validated and supported through his years of experience as an officer of the CIA. His contentions about Bin Laden as a threat to America at the time he was heading the unit was so pronounced and yet, according to him, there have been precisely 10 times when killing Bin Laden was possible but not ordered by then Presidents Clinton and Bush. As clearly identified, he noted that there were two opportunities to kill Bin Laden in May of 1998 through CIA resources and eight times in 1999 through US military aircraft but the President did not clearly order the attack. Missing these opportunities paved the way for Bin Laden’s ability to prove that America can be attacked in their own soil without the need to immediately respond and identify the attackers.

Joffrey Ballet Essay Example for Free

Joffrey Ballet Essay When school is out, dance students have more time to dedicate to training. Choosing a summer intensive program of study can be a challenge, though. How do you know if the program you are considering is a good fit for you? Dance Informa spoke with faculty from The Joffrey Academy, Cary Ballet Conservatory, Straz, Jr. Center for the Performing Arts’ Next Generation and Patel Conservatory’s Dance Department to learn more about what constitutes a great summer program and how you can be prepared to get the most from your experience. What should a student look for in a summer intensive program? Deanna Seay, Ballet Mistress, Cary Ballet Conservatory In looking at a summer intensive, each student needs to evaluate his or her own goals. Does the student want a program where the focus will be on improving technique? Is the student at an age when he/she wants to be considered potential company material? Does the student want an experience focused on one discipline, or does he/she want to use the summer to broaden his/her horizons? Defining these goals can help to narrow the possibilities. A student wanting to improve a lot can look for smaller programs where they will be able to receive personal attention as well as a place that provides many hours of instruction. Those on the verge of professional careers will want to find company related programs. Students wishing to broaden their horizons can look for programs that offer classes in a wide number of dance styles. Students enjoy Patel Conservatory’s Next Generation Ballet Summer Intensive. Photo by Bill Kraulter. Peter Stark, Artistic Director of the David A. Straz, Jr. Center for the Performing Arts’ Next Generation and chair of thePatel Conservatory‘s Dance Department Students should look for: 1. Training. The school should demonstrate a history of training dancers well. Check on their website for recent graduates that are dancing professionally. 2. A schedule that keeps a young dancer busy and working hard. More classes will increase strength and technique. 3. A focus on the type of dance a student wants to study (ballet, modern, jazz) with a sampling of other styles for diversity. 4. A performing and/or rehearsing opportunity. As a performance art, in dance it is important to learn new dances and to get on stage. Alexei Kremnev, Artistic Director, and Amanda McAlpine, Communications Associate, Joffrey Academy and Community Engagement, The Joffrey Ballet Students should assess the quality of a summer intensive program by it’s faculty members (their experience and background), brand recognition (affiliation with professional company), variety of classes provided, performance opportunities, location and length of program. What are the advantages to training locally or going out of state? Peter Stark A family must decide how far they want to travel for a summer program. There is an expense with increased distance. Summer programs can offer a great sampling of an area for future employment. There are many excellent programs worldwide that will improve a young dancer both near and far. Do check out the security of the city, school and dormitory to determine if it meets the family needs. Also, ask about transportation for the students during the program. Students at the Joffrey Ballet Summer Intensive Deanna Seay The most obvious advantage to staying local is the possibility of staying at home while attending the session, or at least being close to home, which can be comforting to both parents and students attending boarding programs the first time. As long as students have access to local programs that provide the number of classes they need, there isn’t really a need to travel far at a young age. Once students reach high school age and are more mature, going out of state becomes an option parents might feel more comfortable with. That being said, there will always be those young students who have the talent and maturity for an out-of-state experience at eleven or twelve. What advice do you have for those taking summer intensive auditions? Alexei Kremnev and Amanda McAlpine It is important to be as prepared as possible. Check the program’s website for any headshots or photos needed, audition fee and attire requirements. If it is possible to pre-register online, it will save you time during the day of the audition. During the audition, do your best and keep a positive attitude. If you excel in a particular area or step, be sure to stand in front or go in the first group. If you are not as strong in other areas, you may want to wait to go in the second group. Regardless, always look pleasant and smile. The judges may not realize that you may have made a mistake because they are concentrating on watching many other dancers too. Peter Stark Always dress neat in a dress code. Do not wear any warm-up shorts, skirts or jewelry. Have a head shot and dance photo (arabesque is good) available even if not specifically requested in the audition announcement. Have a positive attitude and try your best. Often schools are looking for potential, not accomplishment. If a combination isn’t perfect, that’s okay as long as you gave it a good try with a happy demeanor. Try to also pick up any nuance when the teacher is demonstrating the combination. What accents are they using in the music? How are they holding their hands and head? Be open to change and to trying something new. Deanna Seay PAY ATTENTION TO THE DETAILS! Watch everything the teacher does when demonstrating a combination and listen to everything the teacher may say. These details are part of what the teacher will be trying to teach the student, so the students need to prove that they are responsive, receptive and truly interested. Some teachers will be very specific about where students stand and how they enter or exit the dancing space and it is important to understand and adhere to their wishes. When changing groups, students need to walk into formation quickly and place themselves immediately in the starting position. Students should appear neatly dressed. Female ballet students need to wear pink tights and a conservatively colored leotard. Black is traditional and the best choice. Men need to wear the traditional black tights and white t-shirt, which needs to be tucked in. Absolutely under no circumstances should the student wear any sort of cover-ups. Shoes, whether flat shoes or pointe shoes, need to be properly sewn and all drawstrings, ribbons and elastics should be tied and tucked out of sight. Hair should be securely pulled away from the face in a bun, French twist or other practical, yet attractive, shape. What does a summer intensive cost? Students at Cary Ballet Conservatory’s Intensive Summer Training Program. Deanna Seay Families with students wishing to attend a five-week summer ballet intensive will need to prepare to spend about $5,000 for tuition, room and board. A few smaller programs may cost $1,000-2,000 less. Many programs offer financial aid and scholarships, so it is good to ask. Peter Stark. On average most ballet summer intensive programs run about $1,000 per week, including tuition, room and board. However, this can vary greatly and many full and partial scholarships can offset some of that cost. What benefits, aside from technical and artistic, are there to attending a summer dance intensive? Peter Stark Hearing the same correction from a different teacher can open a young dancers’ perspective greatly. Of course, each teacher also has new information that can improve a dancer technically and artistically. Summer programs also pool talent from smaller schools. Students learn from each other and being surrounded by talent can be motivational and create lasting connections through one’s performance career. Many dancers enter the field professionally at 18 and it is a big adjustment to be away from home. A summer program can start to prepare a dancer to be self-sufficient and strong in a new setting. Deanna Seay Aside from the artistic and technical improvement that is often seen during intense summer ballet sessions (attributed to the concentration of class hours), students have a chance to meet other like-minded students and make new friends. The student can become re-inspired by seeing himself/herself in a new setting. These summer programs also expose the student to other students from other schools, and can help the student identify where she stands in relation to her peers. Alexei Kremnev and Amanda McAlpine Attending a summer dance intensive helps a dancer grow and mature in many ways. Often times, students form lasting friendships, make valuable connections, gain confidence and widen their perspectives. Taken from the Dance Magazine.

The Supply Chain Management Of Nike Marketing Essay

The Supply Chain Management Of Nike Marketing Essay Nike is an innovation company, designing and planning for the sustainable economy of tomorrow, not just today. Climate change, and reducing Nikes environmental footprint, is something the company has been focused on for well over a decade, in conjunction with broader sustainability work.   By setting strong targets greenhouse gas emissions from owned operations and business travel were reduced by 18 percent from 1998 to 2005, despite an increase in the square footage of Nikes operations.   The majority of Nikes climate change impact derives from the operations of the more than 700 contract factories producing Nike-branded product.   Given that the transport operations which move Nike product from the point of manufacturing to the distribution centers account for about 25 percent of Nikes CO2 emissions, the company has set a target to reduce the inbound logistics footprint by 30 percent. Supply Chain Management which Nike have in its Considered Design becomes a di ¬Ã¢â€š ¬ erentiator for brands and a source of competitive advantage, company think it is crucial that the consumer has accurate, complete information on not just the delivery of green products, but the extent to which the company is committed to greening its entire supply chain. As early as 2003, Nike developed a baseline of its supply chain general environmental footprint, including inbound logistics and subcontracted manufacturing.As part of the companys Climate Savers agreement, Nike partnered with the University of Delaware to develop a model for measuring inbound emissions of product transportation from factory to  ¬Ã‚ rst distribution facility. Nike is working to expand that model to measure outbound shipments from distribution facility to retail. Footwear contract manufacturing, a majority of which is in Vietnam and China, is another major challenge for Nike. The company has began with audits of key factories to identify energy-intensive processes and potential areas of savings. Nikes US supply chain team has set goals to reduce its overall carbon footprint and is working closely with third-party logistics providers to  ¬Ã‚ nd opportunities to optimize fuel consumption and accelerate the use of alternative fuels. Nike also assessed its packaging footprint as part of a company-wide waste mapping exercise in making excellence in all aspects. The Challenge Finding a business solution that allows this leading apparel and footwear maker to align its demand and supply in a way that minimizes inventory and improve customer service levels. Business users were not satisfied with existing implementation of the demand planning system. The Solution Bristlecone developed and deployed planner DA and SC Policy Manager, composite pre-configured applications that allowed Nike to enforce higher level supply chain policies without having to deal with voluminous SKU Level demand and supply information. The composite apps bridged the gaps between Nikes existing ERP and SCM systems.   Business Impact   Ã‚  Ã‚  Ã‚  Ã‚  > Better ROI from existing ERP and SCM solutions     Ã‚  Ã‚  Ã‚  Ã‚  > Improved visibility into supply and demand     Ã‚  Ã‚  Ã‚  Ã‚  > Planners empowered to better align supply with demand   NIKE, Inc. recognizes the need for a well-coordinated and efficient supply chain for its business and the industry. Because the supply chain spans multiple jurisdictions from raw materials to production to shipping to retail and, ultimately, to consumers, a consistent and mature public policy position is needed. Nike support policies that deliver efficient, cost-effective delivery of NIKE Inc. products in a responsible manner. Our efforts concentrate on ensuring efficient transport, security and safety of NIKE, Inc. products throughout the supply chain. In addition, we advocate for policies that help to ensure that NIKE, Inc.s supply chain from factory to consumer operates in a manner that considers both people and the environment at each step of the way. We work with a number of bodies to advocate for these policies. These include national governments, industry associations and NGOs. Nike see two major changes in their supply chain management system. The first involves the apparel side of our business. With the elimination of quotas,they have changed their sourcing strategy to enter into many more strategic partnerships than they did in the past. Not all of apparel will necessarily be made in China. But going forward,they see many more apparel companies focusing on partnerships, and that should help in injecting more speed and agility into the supply chain management of Nike. 1) The second major change hinges on the need to be more demand-driven. Point-of-sale [POS] technology has progressed significantly in recent years, and POS information is more readily available and also a lot cleaner than it was in the past. At this point, it is up to company to figure out how to use that information to become much more responsive to the needs of our customers and deliver the products at a best suitable procedure and creates the value for time. 2) RFID will no doubt help Nike in a number of ways for continous improvement of supply chain management .RFID is being used to identify inbound and outbound product. RFID is being used in the warehouse to locate product. It is being used in manufacturing and processing industries to track and locate WIP (Work in Progress) and finished goods. RFID is being used to monitor and track product in transit, and RFID is being used to ensure store shelves are replenished.GAO RFID understands that the Supply Chain requires more than one type of RFID technology to satisfy all these different requirements and has developed different solutions for tracking as well locating.But they believe that it has the potential to help us build more demand responsiveness into our supply chain.   Nike has played a leadership role, along with other businesses and multilateral development organizations, in supporting infrastructure development in Vietnam and encouraging supply chain management of nike inc. The first component of the program involved having key Vietnamese government officials visit a Nike footwear factory in Vietnam and subsequently physically follow the movement of finished products from the factory to the port. The group traveled to southern China, an area well known for its development of physical infrastructure. They also visited Singapore to see world-class port facilities and operations and learn about infrastructure planning and financing. Not only the operation of nike in many countries today than they did 10-to-15 years ago, but the regulations in these countries are always changing. For example, back in 1990, the average tariff in India was about 58% for products coming in, and now its about 20% or so. Similarly, the average tariff in China used to be 30%, and today its about 6%. As a result, Nike operates differently today in the global marketplace even in countries where they had a presence for years. Formerly, because of the high tariffs, Nike tended to do mostly local sourcing. But now that tariff rates have fallen and subsequently increasingly starting to do much more deployment of global sourcing space, and thats changing the whole Nikes supply chain network Nike also overhauled its supply-chain system, which often left retailers either desperatel. The old jerry-built compilation strung together 27 different computer systems worldwide, most of which couldnt talk with the others. Under Densons direction, Nike has spent $500 million to build a new system. Almost complete, it is already contributing to quicker design and manufacturing times, and fatter gross margins 42.9% last year. That still-modest portfolio of different brands helps to lessen the companys dependence on hit shoes and could help Nike turn in a more consistent performance. Thats why Nike is eager to snap up complementary brands as they become available. In mid-August it paid $43 million for Official Starter Properties, licensors of sneakers and athletic apparel whose brands include the budget-level Shaq label. What were trying to do is move toward more of a consumer, noncyclical model, says Blair. The key is trying to find the right balance of discipline, innovation, creativity, and structure. Nikes Supply Value Chain In 1984, Nike owned just 16% of the athletic-shoe market, and for much of the 1980s it was running neck-and-neck with Reebok (Wilson 1).    Now, with somewhere between 43-47% of that market, Nike is the undisputed leader. However, things are not perfect with the company.    In the late 1990s, Nike began to see the results of many unresolved issues concerning competitive forces exterior to the company and a value chain, unrepresentative of its marketplace and enormous growth, interior to the company.    Both issues affected its bottom line negatively.    One significant issue was simply a function of poor inventory management and demand forecasting, coupled with the ongoing and dramatic slump in Asian sales. Nike had anticipated a doubling of Asian revenues, but saw instead a decline .   Nike also had recurring problems managing the flow of goods from manufacturers to retailers.    Finally, Nikes competitors, most notably Rebox, New Balance, Adidas and Fila, were copying m uch of the look of Nikes advertising campaigns, making its image projection much less effective.  Ã‚   Nike faced many challenges that they face in building, managing, and expanding global supply chains. Following are some of the nuggets gleaned from their remarks: Ocean freight between Asia and North America routinely takes 45 days or even as long as 60 days, in the event of missed sailing schedules or other problems. When an order is delayed, it has to be expedited through the manufacturing process, and the burden falls on transportation to offset the delays. But trying to make up for lost time by air freighting containers has a ruinous effect on freight budgets. Cross-country cost comparisons for sourcing product should be calculated on an all-in basis, including the costs of ownership along with all other costs incurred across the supply chain. Global supply chains daily involve such vexing problems as complex import-export processes, inadequate logistics infrastructures, and a gauntlet of regulations and trade agreements that are forever changing. When network optimization studies are prepared, they must identify and include the infrastructure-related challenges that are commonplace in emerging markets. Owing to escalating product proliferation, a key challenge is to build more speed, responsiveness, and adaptability into supply chains while still meeting the diverse needs of consumers in different markets. Customers are becoming more sophisticated and demanding, insisting on shorter lead times and faster inventory-turns. To be competitive, suppliers must accommodate these requirements without inflating their cost structures. Looking ahead, freight transport looms as a major source of concern including rising costs, capacity bottlenecks, and homeland security. The relative costs of manufacturing onshore versus offshore are shifting, and the balance could tip in favor of manufacturing beginning to migrate back to the U.S. from offshore locations. Worldwide, Nike faces a huge amount of product proliferation, and their challenge is to build more speed, responsiveness, and adaptability into our supply chains while still meeting the diverse needs of consumers in different markets.They started to create more partnerships with suppliers and carriers and implementing lean manufacturing programs everything and anything that can help us get more flexibility into their supply chain SUPPLY CHAIN MANAGEMENT OF NIKE IN INDIA At Nike which has $16 billion in revenues today with the goal of getting to $23 billion by 2011 process excellence is a key component of the companys supply chain strategy. Nikes three businesses footwear, apparel and equipment have some similarities since most of the products are made in Asia and sold to similar customers worldwide. Their production processes, though, are completely different. Much of this has to do with the fact that from the time Nike began in 1964, it has never owned a factory but has chosen to work through contract manufacturing. They are trying to build our strength in process excellence through standardization and also doing this through the concept of lean manufacturing, which Toyota has made popular. Nike is also working towards what it calls delivery precision. Nike conceives its products in the form of collections. A collection could consist of a top apparel, a bottom apparel, shoes, bag, cap, etc. This is how customers typically like to buy products. While Nike designs these products as part of one collection, each category of items is made in different locations. As a result, if supply chain execution goes awry, these products are not available as complete collections, and that leads to loss of sales. Getting this streamlined is extremely challenging because it involves changing the way contract manufacturers work. Nike supply chains need to support our different businesses and different business models, One of our key challenges is to design supply chains that can leverage what is common and use common platforms and, at the same time, customize parts of the supply chain wherever necessary to meet the end needs of the markets specially in countries like india.

Bad Effects Of Global Warming Education Essay

Bad Effects Of Global Warming Education Essay Barack Obama once said, All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, its here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster. How much more evidence does the national public need to realize that global warming is here? This global phenomenon will affect every human being, and possibly destroy the earth. The New York Times editorial board recently published One Way or Another, in which the members agree that a bill is needed to enforce the rules on how factories and other fuel emitters must respond to decrease the number of carbon dioxide in the atmosphere. Scientists prove it that the planet is getting warmer every yearthe planets temperature has increased by one degree Celsius. The government needs to pass a bill t o prevent factories from producing a large amount of CO2, and the public also needs to take steps to stop global warming, such as using green power, and recycling. The main problem of global warming is the release of carbon dioxide, and other dangerous chemicals in to the atmosphere. These dangerous gases are released when we drive our cars and when factories burn fossil fuels for energy purposes, which will later release carbon dioxide in the air. The carbon dioxide and other gases will get absorbed by the Earths blanket, and then re-radiated back to the planet. This process is called the greenhouse effect, and it helps regulate the earths temperature. It is essential for the Earth, and it is one the Earths natural processes. The only problem is when too much carbon dioxide and other toxic gases are released in to the atmosphere; the Earths temperature could overheat, and cause many problems. (NCDC, 2009) The global surface temperatures have been dramatically increasing since the late 19th century. According to National Oceanic and Atmospheric Administration, the Earths temperature has increased by one degree Celsius in the last 50 years that is an increase of .03 Celsius per year. This evidence proves that the Earths is overheating at a fast pace, and that it will cause problems in the future. If our planet continues to increase in temperature, we will encounter many problems. The United Nations panel on climate change projects that the global temperatures will rise 2-6 degrees Celsius by the centurys end enough to have all the polar caps melted. If the ice caps melt, a majority of countries will be under water. Recent research by the United Nations Panel on Global Warming shows that the ice has been melting already, and their evidence was that the Arctic sea ice has decreased about 23% in the last century. The evidence linking global warming and hurricanes is mounting. The warmer climate is heating up ocean waters, and warm ocean water fuels hurricanes. A 2005 MIT study found that the destructive potential of tropical storms has doubled over the past 30 years. It correlates this increasing ferocity with warmer sea surface temperatures, suggesting a strong link to global warming. Research at the Georgia Institute of Technology found that the number of Category 4 and 5 hurricanes has doubled since the 1970s. (Fight Global Warming, 2008) According to Dr. John Balmes of the American Lung Association of California, higher smog levels may cause serious health problems, including damage to lung tissue, reduced lung function, asthma, emphysema, bronchitis and increased hospitalizations for people with cardiac and respiratory illnesses. Exposure to smog can do serious damage to our lungs and respiratory systems. Inflammation and irritation can cause shortness of breath, throat irritation, chest pains and coughing and lead to asthma attacks. (Fight Global Warming, 2008) Congress has to pass a bill to reduce carbon dioxides levels in the atmosphere, or otherwise the human population is in trouble. According to One way or Another, Senator Barbra Boxer, and John Kerry are going to introduce their long-awaited in bill in December 2009, to impose nationwide limits on greenhouse gas emissions. Lisa Jackson, the administrator of the Environmental Protection Agency, issued proposed rules that would regulate emissions from power plants and other large industrial sources. These government agencies can propose rules, and raise public awareness to stop global warming. One way to reduce carbon dioxide levels in the atmosphere is to be environmental friendly. If people start to purchase hybrid cars it would reduce the CO2 emission by 50 percent. Hybrid cars use half electricity and half gasif we use less gas it will help us protect our environment. Green technology can definitely move us away from being dependent on foreign oil, and save us money in the process. Reducing the amounts of chemicals, plastics, and other items that are harmful to our environment will prevent global warming. We should use green power, which is produced by wind or solar energy. It will make the environment cleaner, and we dont have to burn fossil fuels, coal, and oil; which will increase the carbon dioxide levels. If we switch to green power, we could decrease our energy bills, and as Obama said in One Way or Another, It would also create more jobs in the U.S. The government needs to step up for the public and create a bill that will prevent large factories from producing huge amounts of carbon dioxide. Global warming has to been taken seriously by the general public and that each person should try their best to protect the environment by using green power, and recycling. Precautions must be taken by everyone because global warming will have an effect on all of us. The human race worked so hard to keep this plant safe, why destroy it now? It will be the next generation that will feel the heat!

William Tyndale :: essays research papers

The smell over whelming in the air. The brunt flesh cast a shadow with the dark smoke that the fire created. Some people cheered, some people cried, and yet others smiled greedily under hidden cloaks. The people of England had decided to burn one man that stood up and translated the bible from the original manuscripts into what we have today. William Tyndale cried out with his last breath, " O Lord, open the King of England's eyes." The executioner first strangled Tyndale in order to keep him quiet about "his" word of God. William Tyndale has since become known as "The Father of the English Bible." Without Tyndale and his translation of the original manuscripts later versions of the English bible would not be available. William Hutchinson, later changed to Tyndale, was born around the date of 1494 AD. Tyndale had an exceptional gift of speaking over seven known languages. Tyndale attended Oxford University and in 1512 he received his Bachelors Degree. After another three years at Oxford University Tyndale graduated with a Masters Degree. In order to support his education William Tyndale tutored students from the higher class society. Tyndale joined the group called "the White Horse Society." This group gathered together in order to discuss the teachings of Erasmus and Luther. Then Tyndale was learned and well practiced in God's matters, spared not to show unto them simply and plainly his judgment, and when they at any time did vary from Tyndale in opinions, he would show them in the Book, and lay plainly before them the open and manifest places of the Scriptures, to confute their errors, and confirm his sayings. And thus continued they for a certain season, reasoning and contending together divers times, until at length they waxed weary, and bare a secret grudge in their hearts against him. As this grew on, the priests of the country, clustering together, began to grudge and storm against Tyndale, railing against him in alehouses and other places, affirming that his sayings were heresy; and accused him secretly to the chancellor, and others of the bishop's officers. After a few short years Tyndale left "the White Horse Society" and moved back home to teach children. Tyndale preached at Saint Austen's Green which resided in front of the Cathedral of Bristol. During Tyndale's stay at home he caused a commotion that consisted charging him with heresy. All of this was due to the teachings of the "Lollardry.

Symbolism in The House of Seven Gables :: House of the Seven Gables Essays

Symbolism in The House of Seven Gables  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚        Ã‚   Literature reflects life, and the struggles that each of us must face. Great authors incorporate life's problems into their literature directly and indirectly.   The author bluntly tell us a story, however, he or she may also use symbols to relay to us a message in a more subtle manner.   In Nathaniel Hawthorne's book The House of Seven Gables symbolism is used to enhance the story being told, by giving us a deeper insight into the author's intentions in writing the story.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The book begins by describing the most obvious symbol of the house itself.   The house itself takes on human like characteristics as it is being described by Hawthorne in the opening chapters.   The house is described as "breathing through the spiracles of one great chimney"(Hawthorne 7).   Hawthorne uses descriptive lines like this to turn the house into a symbol of the lives that have passed through its halls.   The house takes on a persona of a living creature that exists and influences the lives of everybody who enters through its doors. (Colacurcio 113)   "So much of mankind's varied experience had passed there - so much had been suffered, and something, too, enjoyed - that the very timbers were oozy, as with the moisture of a heart." (Hawthorne 27).   Hawthorne turns the house into a symbol of the collection of all the hearts that were darkened by the house.   "It was itself like a great human heart, with a life of its own, and full of rich and somber reminiscences" (Hawthorne 27). Evert Augustus Duyckinck agrees that "The chief perhaps, of the dramatis personae, is the house itself.   From its turrets to its kitchen, in every nook and recess without and within, it is alive and vital." (Hawthorne 352)   Duyckinck feels that the house is meant to be used as a symbol of an actual character, "Truly it is an actor in the scene"(Hawthorne 352).   This turns the house into an interesting, but still depressing place that darkens the book in many ways.   Hawthorne means for the house's gloomy atmosphere to symbolize many things in his book.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The house also is used to symbolize a prison that has darkened the lives of its inmates forever.   The house is a prison because it prevents its inhabitants form truly enjoying any freedom.   The inhabitants try to

The Other Side of Paradise :: Free Essays Online

The Other Side of Paradise Any avid viewer of television has seen the advertisement. The sun reflects over a gleaming ocean, ornately dressed women dance in circles, smiling couples dine at sunset, children laugh and run across the beach, then the announcer says, â€Å"come to Barbados, paradise awaits you†. Although I consider myself a grounded and logical person, I confess that each time the announcer alluringly gives the invitation, wistful thoughts run through my head. The idea of leaving behind the chaos of everyday life and retreating to a place of laughter and no worries is truly tempting. I do not even typically enjoy the beach, but the concept of paradise, whatever that may mean, attracts me. Where does the glamour of travel come from? What is it about Americans that makes them desperate to escape? The obvious answer to this, or the counter question would be: what is it about Americans that causes them so much stress? I’ve been told that compared to the rest of the world, Americans spend an average of fifteen percent more time working. A thirty-hour week in Europe is considered a full-time job; In America forty hours is a conservative estimate. Less developed continents have lower employment rates and by default do not place as much emphasis on working. However, in America working and being a contributing part of society is a large part of proving self-worth. This work leads to the need for rest. One author stated that, â€Å"The realization of the need for recreation and travel is an awareness of an affective state usually signaling physical and/or mental exhaustion, and/or social needs such as recognition or inclusion. The need can also come about through a realization of curiosity for certain experiences. Both types of need are often linked with the habitualized oppo rtunity to travel† (Boshoff et. al. 155). Rest comes in many forms; some people find it in exercise, some in zoning out in front of a TV or going out for a nice meal, and others through drugs or alcohol. However travel is somewhat of an American pastime. Most everyone remembers packing up for family vacations in their younger years. Trips to the store for sunscreen, bug spray and snacks, fights over who gets the window seat, games to entertain on the trip, and threats by exhausted, frustrated, and often lost parents are all parts of growing up.

Alexander Shulgin

Ever sense my freshman year in high school, I have always expressed extreme interest in biochemistry and pharmacology. I believe this is because in the past, I have been prescribed many different antidepressant and ADHD medications. I was always very curious as to how these psychoactive medications worked. I would look them up and read all about the different types of antidepressants and how they worked. From selective serotonin reuptake inhibitors (SSRl's) to Norepinephrine- dopamine reuptake inhibitors (NDRl's).My fascination with different medications and ow they worked brought me to many different famous biochemists and chemical engineers, but there was one man who always stood out to me. A â€Å"rogue chemist,† named Alexander Shulgin. Sasha, as his friends call him, is widely famous for his discovery of over 230 different psychedelic drugs varying from the 2C family, DOX family, and various other phenethylamines & tryptamines. Even with such a gargantuan amount of accomp lishments, Shulgin is most famous for rediscovering and resynthesizing methylenedioxymethamphetamine, or as it is most commonly recognized as, MDMA.MDMA is a semi-synthetic drug first discovered some time before 1912. A german pharmaceutical company called Merck first discovered and patented this compound while searching for a medication that would stop bleeding. They never tested it orally, and therefore never found a real purpose for it. Decades later, on September 8, 1976, Sasha synthesized MDMA. Two years later, the first human study was published by Sasha and another chemist by the name of Dave Nichols. They described the effects as â€Å"an easily controlled altered state of consciousness with emotional and sensual overtones. When Sasha discovered its effects after ingestion, he introduced this compound to many psychiatrists, in order for them to allow patients to ingest a small dosage in order to help them speak more freely. The psychiatrists were so impressed by the effects of using MDMA in psychotherapy that they would speak to other colleagues. Word spread very quickly, and many people were astounded by how well it worked. Many patients were reported to have said that one session with an administered dosage of MDMA felt like years of therapy.As word got out about a drug that gave you empathy and self-acceptance, use of MDMA slowly became more public. Companies were mass producing this substance and selling it legally due to the fact that if users took a higher dosage, they would feel vast amounts of euphoria. As more reports of MDMA abuse were put in media, the DEA decided to schedule MDMA in the schedule one category. This means they had to prove that MDMA had a high potential for abuse while having no medicinal benefits.Many therapists challenged this idea, and after years of debate, MDMA was scheduled. I can only imagine how upset Shulgin could have been. He had found what was called â€Å"penicillin for the soul. † He had Just discovered a miracle drug capable of llowing a different outlook on life. It allowed patients to open up not only to others, but to themselves. He had heard so many reports from patients exclaiming how this therapy nad changed their lives and allowed them to diagnose their issues and even solve them.It is commonly said that MDMA could still be legal to this day if it had not been for the rave movement and ignorance of others. Sasha has not been shy about letting others know that he is very upset with the outcome of such a powerful medication, and for good reason. He has worked with the Drug Enforcement Administration many times and has eceived many awards for his work. In fact, in order to carry out consulting work with the DEA, Shulgin obtained a DEA Schedule I license for an analytical laboratory, which allowed him to possess and synthesize any illicit drug.Sasha set up a chemical synthesis laboratory in a small building behind his house, which he uses to synthesize and test the effects of p sychoactive drugs to this day. His laboratory is littered with Jars and Jars of various compounds with their chemical structure drawn on them, which he calls his dirty pictures. Over the course of this time, he has written nd recorded the synthesis of these various compounds in two different books titled PIHKAL (Phenethylamines I Have Known and Loved) and TIHKAL (Tryptamines I Have Known and Loved). He is working on his last book now.Even with his many accomplishments, Shulgin is in no way rich. His only source of income continues to be from the books he has published. He has never sold any of his substances or withheld information on how to synthesize certain compounds. His creations have only made their way to the streets through chemists in China who read through his books and notes and create these compounds in their laboratories o then export to the United States in a completely legal manner, as these drugs are almost completely unheard of and unclassified.As Sasha gets older, he suffers from many different ailments, and has no way to pay for them except through donations, which he has only recently started to accept. He lives a quiet, modest life with his wife and he refuses to conduct any more interviews. I understand why many people consider drugs a taboo subject. I am sure some people may even consider it inappropriate to discuss in a high school classroom, but l, Just like Alexander Shulgin and many others, find extreme interest in psychoactive ompounds and how they can affect our world.Without the study of the more extreme side effects of compounds, how we can expect to progress in our world of modern medicine? Just because a chemical can be abused, does not mean that we should probihibit not Just the possession of said compound, but also the study of it. We live in a world of fear and ignorance, and if we do not fght it, we will never progress. If Sasha has taught me anything, it is to fight for what I believe is morally correct, and I advise you a ll to do the same. Long live Alexander Shulgin and his dirty pictures.
