Case For or Against the War on Drugs Research Paper

Case For or Against the War on Drugs - Research Paper Example Despite many apparent set backs, the war on drugs has made tremendous gains in the making of the world a safer place. There have been concerted efforts in the United States over the past 40 years since then serving President Richard Nixon launched the U.S Government’s war on drugs.1 Several steps of progressive have been made against the flourishing of drug use and sale in the U.S. One such stride has been the advocacy for a paradigm shift in the war against drugs. As was expressed by President Obama in a digital town hall meeting, in 2011, there is a need to move from the old approach of the war to a new one. One way of accomplishing this has been looking at ways of shrinking demand for the drugs among the users.2 This represents a shift from looking at this war as primarily a criminal justice problem3. When looking at the war on drugs as a criminal justice problem, the emphasis on tackling it involves arrest, incarceration, and interdiction4. While this has had good results, it has had the unfortunate disadvantage of letting some of the offenders to slip through the cracks. Currently, there is a move towards looking at the war on drugs as a public health problem.5 This means that the government has acted as a guardian of the public interests6. This thus means that the government has managed to win the hearts of the people who advocate for social justice in the country. Another gain in the war on drugs was the Reagan administration’s efforts to take away the drugs from the consumers through efforts to cut down the crop abroad. This effort can be seen in countries like Bolivia. In this country, the efforts to reduce the drug production saw the seizure of twenty-seven tonnes of cocaine in 1986. This was an improvement from just one tone netted in 1981.

Nazi germany - Research Paper Example For instance, top administrators communication was answerable to Hitler and pursued his regulations, but they had some significant autonomy. The state was not a controlled, working jointly organ, but instead an assortment of blocs struggling to accumulate power and get support from Fuhrer. At the center of the Great Depression, the Nazi Government reinstated growth and stop mass joblessness by use of heavy military costs alongside mixed economy of central-scheming, as well as free-market practices. Wide carrying out of public works comprising construction of the Autobahns. The restoration of economy offered the regime substantial popularity; for instance, the restraint of all resistance made Hitler’s power largely unconcealed (Heller 243). Racisms, mostly antisemitism that was practiced were the fundamental precept of the Nazi German. German developed largely vibrant demands on the Jews, claiming declaration of war in case such demands were not fulfilled. Nazi German as a move ment that developed among fuming young scholars in early 1920s. The movement declined the Treaty of Versailles (1919), democracy general, as well as the Weimar republic. This group of young veterans call for the restoration of the Aryan race and accused the Jews for Germany’s challenges. ... ovement, it assured its subject of concrete authoritarian power, radical economic rules, civil peace, raised lebensraum for Germanic citizens, creation of the national society depended on racial cleansing and race through the vibrant Jews suppression. In addition, the Nazis pledged cultural as well as national regeneration depending on the Volkisch organization, suggested rearmament, traditionalism, reclamation, as well as the repudiation of reparations of borders lost to the Treaty of Versailles (Tooze 211). How German descend fast to a dictator state When Hitler was elected in January 1933, German state still enjoyed democratic form of government. Germany always had fair elections where no one had the power to be abused while voting. There were multiple political parties where citizens could choose for themselves which party could deliver and provide them with the desired leadership. On the other hand, to pass a law, the Reichstag had to accept to the new law following the bill goi ng through the common procedure of debate, opinions etc. The members of the Reichstag of 1933 comprised of 50% members who were against the Nazi Party. Thus, it would have been highly impossible for Hitler to make pushed into law what he proposed. Most thought of Hitler as a fall-member politician that may have to take responsibility to blame in case things got worse over his rule. Hitler had assured a general election for March 1933 of which this may have been, within his mind, the best chance for him to demonstrate all politicians who differed with him where the actual loyalties stay among the German citizens. A week prior to election was set to occur, the Reichstag building went up in flames. Hitler quickly claimed that it was the symbol for the communist conquers of the county. Hitler

Long-Term Liabilities (Assignment 9) Assignment Example | Topics and Well Written Essays - 500 words

Long-Term Liabilities ( 9) - Assignment Example Long-term income taxes payable recorded a negative change of 49.44% from the previous. This clearly indicates that the company reduced its long-term income tax payable by 49.44 percent. This is a good sign of the efforts of the company tom reduce long-term liabilities. According to the notes on the financial statements, the management of the company recorded that the company recorded a significant reduction in income tax payable as a result of changes in tax policies. The U.S. federal and state tax audits resolved to lower the rate of income tax rate from 32.5 percent in April 2, 2011 to 12.7 percent in March 31, 2012. 3. What are the approximate interest rates incurred on your firms long-term liabilities? Complete the schedule below. Some items, e.g., deferred tax liabilities, do not incur interest. Some (or most) of this information will be found in the notes to the financial statements. 5. Go to the statement of cash flows. Observe the amount of "net cash flow from operations" generated in each of the last three years. To what extent does it appear that the company will be able to pay off the above scheduled obligations each year with cash generated from operations? Might the company need to raise the required cash in some other way? Discuss. The company has been recording consistent increase in the amount of net cash flow from operations. In the last financial year ended in December 2011, the Pentair recorded a net cash flow from operations of 320,226,000. This is remarkable given the fact that the company has been recording consistent performance in the last three years. Taking a look at both the present and past performances of the company, the company is only able to pay long term debts. The other obligations have the effect of straining the company’s financial resources and this may require the company to source for additional capital. The company may pay the obligations by raising additional capital from the stock market through

Library and Its Uses Essay Example for Free

Library and Its Uses Essay The root-meaning of the word library is a room or building containing a collection of books for reading. But as there are now circulating or travelling libraries in many countries, the world has undergone a change in its meaning. By the word now indicated a collection of books for reading or reference; Different kinds of libraries: There are kinds of libraries personal, public and institutional. Personal library A personal library is one which belongs to a private person, generally of sufficient means. Such libraries grow out of such person’s taste for knowledge and, sometimes, for fashion. There are, of course, small scale private libraries owned by solvent lawyers, educationists and persons of literary taste. But such libraries contain books on some particular subject or subjects chosen according to the taste and interest of their owners. Public library A public library is one which is open to the public. In order to cater to the taste and interest of all classes of people, a public library has to contain books on different subjects and varieties. Such libraries may be seen in large numbers in every country. Most of these libraries are managed or subsidized by their states. The British Museum library of London and the Central library of Moscow are instances of public libraries. Again, many such libraries have been set up in England and America by philanthropic people like Mr. Carnegie, the American millionaire. Institutional library An institutional library is one which belongs to an institution such as a university, a college, a school, a chamber of commerce, a club or a governmental department. Such a library is open to the members of the institution concerned and, therefore, generally contains hooks which are needed by them most. Importance of library As acquisition of knowledge depends mostly on reading, man has to read as necessarily as he has to eat. It adds to what he has already learnt and makes him strong and fit for rude battle of life. But for financial difficulties most of the persons who are keen on reading cannot purchase the books they need to read. Hence arises the importance of libraries. Had there been no libraries, both public and institutional, such persons would have been deprived of their reading. The teachers and the students, in like manner, would be badly affected if their institutions had no libraries of their own. Conclusion Libraries attract people to read and thus create the habit of reading and- stimulate the thirst for more and more knowledge. But for the libraries, there would be no authors, no poets, and no thinkers. The libraries thus help in the advancement of learning and expansion of knowledge. The library has another very important use. No research work is possible without a well equipped library containing valuable books of all ages, rare manuscripts and old records. A library of this type is thus of incalculable help in throwing light on unearthed subjects. Time passes in an unbroken continuity as does the water of the river. The books of the libraries are a record of this continuity. They thus enable us to know how human society has developed in thought and action step by step.

Camaro Essay -- Automobiles Chevrolet Camaros Essays

Camaro The name â€Å"Camaro† came from a French word for friend. The decision on the name came down to the last minute, with most of the world sure the car would be named, â€Å"The Panther.† Although the strange name had to be explained to the public, Camaro fit in with other Chevy names- Corvette, Chevelle, Chevy 2, and Corvair. The main reason the Camaro was introduced was because of the huge success of the Ford Mustang. The Camaro was roughly the same size as the Mustang, a little wider and based more on performance. The Camaro is one of the last remaining muscle cars still in production today. It is only fitting that buyers still expect maximum performance from their Camaros. It is that expectation that has kept the Camaro alive for all these years, while many other cars have faded away, lost in memory. The Mustang GT only only offered the 289- cubic inch or an 390- cubic inch V8 in 1967. The Camaro rolled out with 302, 327, 350, and 396 cubic inch V8’s (Camaro 14) The Camaro’s style was much smoother as well. The introduction of the Camaro threw pony car development into a frenzy. Before the Camaro, the Mustang and Barracuda were not quite considered full muscle cars. Most serious performance enthusiasts still opted for intermediate sized GTO’s or the Chevelle Super Sports (SS). The Camaro changed the image of those sport coupes. (Camaros, Eric Ethan) The Z28 and the stout SS-396 were more than just a stylish ride. Under the hood Camaros were well respected. Such respect helped establish the Camaro as the premier high-performance pony car. Camaro sales increased each year form 1967-1969. To this day, these Camaros are the favorite among enthusiasts. The Camaro brings a bad-boy image to the street and the track. The car has always been based on racing even when the Camaro was not officially involved. â€Å"It’s at home drag racing, and racing away from convenience stores after hold-ups. Because of this, media has given the Camaro a bad boy reputation.†(American Muscle Cars, 47) 1969 saw several noteworthy changes to the Camaro. The grill became deeper set, the taillamps were longer and thinner and broken into three segments. A heavy "eye-brow" crease was added on the both sides of the car extending from the front wheel well to the rear wheel well. A matching crease went from the rear wheel well to the rear quarter panel. Endura rubbe... ...white was perhaps better suited to the older cars, but the look was still striking. Chevrolet even revived the interior with 30th anniversary logos. White wheels added to the effect. 1998 was a big year for the Camaro. It received a major refreshening with body upgrades including a new front fascia, a new hood, composite reflector headlamps, and new fenders. The 1998 model also received chassis upgrades, a new 4-wheel disc brake system and a new anti-lock brake system (ABS). But the biggest upgrade was the all new LS1 V8 engine for the Camaro Z28. This new engine produces 335 horsepower. That’s more than twice the standard horsepower offered in the 1982 Z28, to shine a little perspective on the state of modern high-performance. Although most Camaros sold through the years have not been performance models, it is still the image and reputation of the various Super Sports, Z28’s, Pace Cars, and IROC-Zs that have defined the Camaro and kept the car in the public eye. While other car fashions have changed, Camaro buyers still want powerful V8s driving the real wheels, preferably with a manual transmission between the two. Given the opportunity, they will buy performance.

Lab 5 Cellular Respiration

Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule, such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates, proteins, and fats can all be metabolized as fuel, but cellular respiration is most often described as the oxidation of glucose, as follows: C6H12O6 + 6O2 > 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain.Glycolysis is a catabolic pathway that occurs in the cytosol and partially oxidizes glucose into twopyruvate (3-C). The Krebs cycle is also a catabolic pathway that occurs in the mitochondrial matrix and completes glucose oxidation by breaking down apyruvate derivative (Acetyl-CoA) into carbon dioxide. These two cycles both produce a small amount of ATP by substra te-level phosphorylation and NADH by transferring electrons from substrate to NAD+ (Krebs cycle also produces FADH2 by transferring electrons to FAD).The electron transport chain is located at the inner membrane of the mitochondrion, accepts energized electrons from reduced coenzymes that are harvested during glycolysis and Krebs cycle, and couples this exergonic slide of electrons to ATP synthesis or oxidative phosphorylation. This process produces 90% of the ATP. Cells respond to changing metabolic needs by controlling reaction rates. Anabolic pathways are switched off when their products are in ample supply. The most common mechanism of control is feedback inhibition.Catabolic pathways, such as glycolysis and the Krebs cycle, are controlled by regulating enzyme activity at strategic points. A key control point of catabolism is the third step of glycolysis, which is catalyzed by an allosteric enzyme, phosphofructokinase. The ratio of ATP to ADP and AMP reflects the energy status o f the cell, and phosphofructokinase is sensitive to changes in this ratio. Citrate and ATP are allosteric inhibitors of phosphofructokinase, so when their concentration rise, the enzyme slows glycolysis.As the rate of glycolysis slows, the Krebs cycle also slows since the supply of Acetyl-CoA is reduced. This synchronizes the rates of glycolysis and the Krebs cycle. ADP and AMP are allosteric activators for phosphofructokinase, so when their concentrations relative to ATP rise, the enzyme speeds up glycolysis, which speeds of the Krebs cycle. Cellular respiration is measure in three manners: the consumption of O2 (how many moles of O2 are consumed in cellular respiration? ), production of CO2 (how many moles of CO2 are produced in cellular respiration? , and the release of energy during cellular respiration. PV = nRT is the formula for the inert gas law, where P is the pressure of the gas, V is the volume of the gas, n is the number of molecules of gas, R is the gas constant, and T is the temperature of the gas in degrees K. This law implies several important things about gases. If temperature and pressure are kept constant then the volume of the gas is directly proportional to the number of molecules of the gas. If the temperature and volume remain constant, then the pressure of the gas changes in direct proportion to the number of molecules of gas.If the number of gas molecules and the temperature remain constant, then the pressure is inversely proportional to the volume. If the temperature changes and the number of gas molecules is kept constant, then either pressure or volume or both will change in direct proportion to the temperature. Hypothesis: The respirometer with only germinating peas will consume the largest amount of oxygen and will convert the largest amount of CO2 into K2CO3 than the respirometers with beads and dry peas and with beads alone.The temperature of the water baths directly effects the rate of oxygen consumption by the contents in the respirometers (the higher the temperature, the higher the rate of consumption). Materials: The following materials are necessary for the lab: 2 thermometers, 2 shallow baths, tap water, ice, paper towels, masking tape, germinating peas, non-germinating (dry) peas, glass beads, 100 mL graduated cylinder, 6 vials, 6 rubber stoppers, absorbent and non- absorbent cotton, KOH, a 5-mL pipette, silicon glue, paper, pencil, a timer, and 6 washers. Procedure:Prepare a room temperature and a 10oC water bath. Time to adjust the temperature of each bath will be necessary. Add ice cubes to one bath until the desired temperature of 10oC is obtained. Fill a 100 mL graduated cylinder with 50 mL of water. Add 25 germinating peas and determine the amount of water that is displaced. Record this volume of the 25 germinating peas, then remove the peas and place them on a paper towel. They will be used for respirometer 1. Next, refill the graduated cylinder with 50 mL of water and add 25 non-germinating peas to it.Add glass beads to the graduated cylinder until the volume is equivalent to that of the expanded germinating peas. Remove the beads and peas and place on a paper towel. They will be used in respirometer 2. Now, refill the graduated cylinder with 50 mL of water. Determine how many glass beads would be required to attain a volume that is equivalent to that of the germinating peas. Remove the beads. They will be used in respirometer 3. Then repeat the procedures used above to prepare a second set of germinating peas, dry peas and beads, and beads to be used in respirometers 4,5,and 6.Assemble the six respirometers by obtaining 6 vials, each with an attached stopper and pipette. Then place a small wad of absorbent cotton in the bottom of each vial and, using the pipette or syringe, saturate the cotton with 15 % KOH. Be sure not to get the KOH on the sides of the respirometer. Then place a small wad of non- absorbent cotton on top of the KOH-soaked absorbent cotton. Repeat the se steps to make the other five respirometers. It is important to use about the same amount of cotton and KOH in each vial. Next, place the first set of germinating peas, dry peas and beads and beads alone in vials 1,2, and 3.Place the second set of germinating peas, dry peas and beads, and glass beads in vials 4,5, and 6. Insert the stoppers in each vial with the proper pipette. Place a washer on each of the pipettes to be used as a weight. Make a sling using masking tape and attach it to each side of the water baths to hold the pipettes out of the water during the equilibration period of 10 minutes. Vials 1,2, and 3 should be in the bath containing water at room temperature. Vials 4, 5, and 6 should be in the bath containing water that is 10oC. After the equilibration period, immerse all six respirometers into the water completely.Water will enter the pipette for a short distance and stop. If the water does not stop, there is a leak. Make sure the pipettes are facing a direction f rom where you can read them. The vials should not be shifted during the experiment and your hands should not be placed in the water during the experiment. Allow the respirometers to equilibrate for three more minutes and then record the initial water reading in each pipette at time 0. Check the temperature in both baths and record the data. Every five minutes for 20 minutes take readings of the water’s position in each pipette, and record.Results: In this activity, you are investigating both the effects of germination versus non-germination and warm temperature versus cold temperature on respiration rate. Identify the hypothesis being tested on this activity. The rate of cellular respiration is higher in the germinating peas in cold than in the beads or non-germinating peas; the cooler temperature in the cold water baths slows the process of cellular respiration in the both germinating and non-germinating peas. This activity uses a number of controls. Identify at least three of the controls, and describe the purpose of each.The constant temperature in the water baths yielding stable readings, the unvarying volume of KOH from vial to vial leading to equal amounts of carbon dioxide consumption, identical equilibration periods for all the respirometers, precise time intervals between measurements, and glass beads acting as a control for barometric pressure all served as controls. Describe and explain the relationship between the amount of oxygen consumed and time. There was a constant, gradual incline in the amount of oxygen consumed over precise passage of time.Why is it necessary to correct the readings from the peas with the readings from the beads? The beads served as a control variable, therefore, the beads experienced no change in gas volume. Explain the effects of germination (versus non-germination) on pea seed respiration. The germinating seeds have a higher metabolic rate and needed more oxygen for growth and survival. The non-germinating peas, t hough alive, needed to consume far less oxygen for continued subsistence. Above is a sample graph of possible data obtained for oxygen consumption by germinating peas up to about 8oC. Draw in predicted results through 45oC.Explain your prediction. Once the temperature reached a certain point, the enzymes necessary for cellular respiration denatured and germination (and large amounts of oxygen consumption) was inhibited. What is the purpose of KOH in this experiment? The KOH drops absorbed the carbon dioxide and caused it to precipitate at the bottom of the vial and no longer able to effect the readings. Why did the vial have to be completely sealed under the stopper? The stopper at the top of the vial had to be completely sealed so that no gas could leak out of the vial and no water would be allowed into the vial.If you used the same experimental design to compare the rates of respiration of a 35g mammal at 10oC, what results would you expect? Explain your reasoning. Respiration wou ld be higher in the mammal since they are warm-blooded and endothermic. If respiration in a small mammal were studied at both room temperature (21oC) and 10oC, what results would you predict? Explain your reasoning. Respiration would be higher at 21 degrees because it would be necessary for the animal to maintain a higher body temperature.The results would proliferate at 10 degrees because the mammal would be required to retain its body temperature at an even lower temperature in comparison to room temperature. Explain why water moved into the respirometer pipettes. While the peas underwent cellular respiration, they consumed oxygen and released carbon dioxide, which reacted with the KOH in the vial, resulting in a decrease of gas in the pipette. The water moved into the pipette because the vial and pipette were completely submerged into the bath. Design an experiment to examine the rates of cellular respiration in peas that have been germinating for 0, 24, 48, and 72 hours.What res ults would you expect? Why? Respirometers could be set up with respirometer 1 containing non-germinating peas, respirometer 2 holding peas that have been germinating 24 hours, 3 would contain the peas that germinated 48 hours, and 4 would hold the peas that germinated 72 hours. All the respirometers should have the KOH added to the bottom in the same manner as in lab described earlier. The respirometers should be placed in baths with the same temperature for all the respirometers. The seeds that have not begun germination would consume very little oxygen.The peas that have been germinating for 72 hours will have the greatest amount of oxygen consumption, while the other two samples will consume a medium (in comparison to respirometers 1 and 4 results) amount of oxygen. Error Analysis: Numerous errors could have occurred throughout the lab. The temperature of the baths may have been allowed to fluctuate, the amounts of peas, beads, KOH, and cotton may have varied from vial to vial da maging the results, and these problems would have occurred only during set up. Air may have been allowed to creep into the vial via a leaky stopper or poorly sealed pipette.Timing for the equilibration of the respirometers and the five-minute time intervals may have been erroneous. It was somewhat difficult to read the markings on the pipettes and so errors are always likely. Mathematical inaccuracies may have taken place when filling out the table and finding the corrected difference by using the formula provided. Discussion and Conclusion: The lab and the results gained from this lab demonstrated many important things relating to cellular respiration. It showed that the rates of cellular respiration are greater in germinating peas than in non- germinating peas.It also showed that temperature and respiration rates are directly proportional; as temperature increases, respiration rates increase as well. Because of this fact, the peas contained by the respirometers placed in the water at 10oC carried on cellular respiration at a lower rate than the peas in respirometers placed in the room temperature water. The non-germinating peas consumed far less oxygen than the germinating peas. This is because, though germinating and non-germinating peas are both alive, germinating peas require a larger amount of oxygen to be consumed so that the seed will continue to grow and survive.In the lab, CO2 made during cellular respiration was removed by the potassium hydroxide (KOH) and created potassium carbonate (K2CO3). It was necessary that the carbon dioxide be removed so that the change in the volume of gas in the respirometer was directly proportional to the amount of oxygen that was consumed. In the experiment water will moved toward the region of lower pressure. During respiration, oxygen will be consumed and its volume will be reduced to a solid. The result was a decrease in gas volume within the tube, and a related decrease in pressure in the tube.The respirometer with just the glass beads served as a control, allowing changes in volume due to changes in atmospheric pressure and/or temperature. This activity uses a number of controls. Identify at least three of the controls, and describe the purpose of each. The constant temperature in the water baths yielding stable readings, the unvarying volume of KOH from vial to vial leading to equal amounts of carbon dioxide consumption, identical equilibration periods for all the respirometers, precise time intervals between measurements, and glass beads acting as a control for barometric pressure all served as controls.Describe and explain the relationship between the amount of oxygen consumed and time.

Responding to the Wii Essay

Kazuo Hirai, the chief executive of Sony Computer Entertainment Inc. (SCEI) has encountered two large rivals in the video game industry this year. Nintendo and Microsoft have released advanced video game consoles that have left Sony sales behind. Nintendo especially, has broken the status quo for marketing in the video game industry by dramatically expanding its target market from 18-34 year-olds to 9-65 year-olds both male and female with its new video game console, the Wii. For years, Sony had gone head to head with Microsoft competing for the same market with their PSPs and X-Boxes consoles. Both Sony and Microsoft focused on using advanced technology to create cutting edge video game consoles whose purpose was more than just video games. Their target market was 18-19 year old males. On the other hand, the Wii is not as advanced as the PSP or X-Box. Its main attraction are its wireless, motion-sensing controllers that allow gamers to use their limbs (punching, swinging, batting) to control the actions of on-screen characters. Also, the Wii was designed with user- friendly capabilities that appeal to all audiences. Nintendo is threatening competition for Sony. There are five main forces that drive Video Game Industry competition: * Intensity of rivalry among Competitors * Threat of New Entrants * Threat of Substitutes * Bargaining Power of Suppliers * Bargaining Power of Buyers Strategic Issues Intensity of Rivalry among Competitors One of Sony’s largest threat and competitor is Nintendo. Nintendo sold 32.4 million units for the Wii, while Sony sold 15.5 million units. While Sony was occupied retaliating to Microsoft’s X-box video game console, Nintendo rose to take number one position in the video game industry. In 2007, Sony lost 9.7% of its Operating Margin, while Nintendo was up to 58.8% in millions of dollars. This is an important issue because Sony has been at the top of the industry for many years and is now suddenly is losing capital. Currently in the Video Game industry rivalry and competition is really intense. In Sony’s case, it is the way Nintendo’s Wii console is appealing to all audiences that has affected Sony the most. With Sony only reaching out to a closed market, it is difficult to increase sales. Also, Sony has to keep up working on new technology for the PSP to overcome Microsoft’s X-box. If Sony does not step up its g ame, then soon it will be left behind and sales will hit the floor. Threat of New Entrants Sony’s second rival in sales is Microsoft and their video game console, the X-box 360. Microsoft threatens to take control of the gaming market of 18-35 year olds. Microsoft brought out the new X-box live that allows players to play online with players from all over the world while video chatting with them at the same time. If Sony does not address the issue with the Wii, and does not improve sells, Microsoft could take over Sony’s target market. This force is moderately strong, and is another threat to Sony. Threat of Substitutes In Sony’s case, if Sony does not respond to the Wii or X-box and loses its target market new entrant s might join the video game industry to take advantage of the lack of motivation from Sony and their target market. Sony needs to make sure it keeps their current target market by providing improved technology and new games. If not, then there could be a possibility that new competitors come into play and take Sony’s position as lead video game provider for 18-35 gamers. Also, Nintendo could just take over the whole Video Game industry. Although, this force is not very strong it can definitely happen, especially with Sony’s sales loss. Bargaining Power of Suppliers Currently, Sony is not being affected by the bargaining power of suppliers. However, the companies that it does work with (Toshiba and IBM) could refuse to manufacture new products for Sony if they feel they are taking a risk based on Sony’s drop in sales. For example when Microsoft joined the Video Game Industry it attempted to do things differently, like not charging royalties to third parties, thus third party console makers declined to manufacture x-boxes. This is also a moderate force that must be kept on check because whatever Sony’s decision is to do in respond to the Wii, Sony will have to go to these third parties to manufacture the new ideas. Bargaining Power of Buyers For Sony, there is not a lot of bargaining power from buyers. The issue is that its market is not as large as Nintendo’s. This force is not an immediate threat to Sony but rather would happen in a case where a company was forced to reduce the price of its video game console to please its market. The main issue in the Video Industry is not the cost of the product but rather the quality and popularity amongst the market. Recommendations Of all these five forces that drive Video Game industry competition, the strongest forces are the intensity of rivals and threat of new entrants. Sony should not try to compete with Nintendo for the market, but should instead focus on its strongest facets in order to keep pleasing their current target market. Sony has become very popular amongst its target market and if it is not focused it can become weak and lose its market. If this happens then Microsoft would take Sony’s position and market and have no other main competitors. If Sony can improve sales by pleasing its target market, then the other four forces can be avoided. Sony should stay focused on finding new technology to improve its current game console to please its current target market. This market has been following Sony since its birth and should be Sony’s priority. Rushing into a larger market could damage Sony even more. The Video Game industry is definitely an attractive business for So ny, but Sony should be aware of its competitors and keep its product high quality.
