Dispute settlement mechanism in the WTO and developing countries Essay

Dispute settlement mechanism in the WTO and developing countries - Essay Example The purpose of this paper is to examine the mechanism of the world trade organization to settle the disputes that occur between the parties of the organization. Research will compare the system of GATT and the WTO system to settle disputes. In addition; it will explain how the system works. Also it will show the benefits that the system provides for developing countries. And it will be some cases of the disputes that the system remedied. The increasing predominance of the capitalist system, globalization and the consequent reduction of the world into some form of global village have resulted into the fast integration of the world’s economic system. This development is characterized by countries engaged in constant bilateral and multilateral relationships as they deal with each other with the highly dynamic and freer flow of goods and services in the international market in addition to the internationalization of production. David Held (1999) argued that historical evidence at both the world and country levels demonstrate that the higher level of trade today is inevitable – from the Classical Gold Standard period to the postwar growth in trade.1 An illustration of the growth of global trade is demonstrated in fig. 1. This phenomenon was made possible by the advances in modern technology, transportation and communications as well as the global trade liberalization that have paved the way for a highly evo lved economic system. Central to globalization is the World Trade Organization, the international body that institutionalized the world trade system. It is this organization that has worked to increase trade between countries by ensuring that tariffs, state control systems are lowered and protectionism by governments on domestic industries is eliminated. The environment that is created by the modern economic system often breeds conflict as countries navigate the complexities of trade. As nation-states become naturally enmeshed and interdependent

Love and Sex Relationship Essay Example | Topics and Well Written Essays - 750 words

Love and Sex Relationship - Essay Example Sexual relationship between man and woman before marriage: ethical or not Within the context of love and sex relationship, sexual relationship between man and woman before marriage is unethical because it leads to a number of problems in future life. For instance, one cannot prove that sexual relationships ultimately lead to marriage in future. If a partner is in search of temporary relationship, the other partner is forced to face the consequences. If one considers that marriage is related to sexual purity of the partners, sexual relationship between man and woman before marriage is unethical. If one is not pure, one cannot blame others. Nicotera opined that â€Å"After sharing all that there is to share before marriage, it is believed that young couples get bored with each other soon after marriage because they did not leave anything to imagination or delay any satisfaction† (172). From a different angle of view, sexual relationship before marriage increases the scope of bor edom in future life. On the other side, difference in opinions related to sexual relationship before marriage is deeply influenced by cultural difference. In an underdeveloped society, laws and regulations related to marriage may be strict. In this situation, sexual relationship between man and woman before marriage is unethical. Within the context of developed societies, sexual relationship before marriage is considered as the best possible way for the partners to know each other in a different way. Still, one can indulge in a love affair without sex because it does not force him or her to feel regret. Virginity: important to men or women One can see that virginity is important to men and women because men and women are equal. If one considers that virginity is important to women, one is trying to devalue the status of womenfolk. To be specific, marriage is an agreement between equal partners and virginity is applicable to both the partners. If a man is so cautious about his partne r’s virginity, he must realize the fact that the same is applicable to him also. Klein stated that â€Å"In the case of the Middle East, early marriage appears to be corollary to the emphasis on female virginity; the earlier the marriage, the less likelihood that the girl will lose her virginity before marriage† (60). If an individual is ready to accept marriage as an important agreement or social contract between the partners, virginity is important to both the partners. So, within the context of love and sex relationship, one can see that virginity is important to men and women. On the other side, most males expect that their partners must be cautious about their virginity. But most males are not aware of the fact that their female partners can question their status on virginity. The women folk who are in favor of sexual independence and individual freedom are not in favor of virginity. From a different angle of view, virginity of men and women is a controversial top ic which can be evaluated according to individual difference. Still, virginity should not be considered as the most important aspect of marriage because trust and cohesion between partners is most important. Teenage sex

All About Screw Pumps Engineering Essay

All About Screw Pumps Engineering Essay Screw pumps are rotary, positive displacement pumps that can have one or more screws to transfer high or low viscosity fluids along an axis.   A classic example of screw pumps is the Archimedes screw pump that is still used in irrigation and agricultural applications.   Although progressive cavity pumps can be referred to as a single screw pumps, typically screw pumps have two or more intermeshing screws rotating axially clockwise or counterclockwise.   Each screw thread is matched to carry a specific volume of fluid.   Like gear pumps, screw pumps may include a stationary screw with a rotating screw or screws.   Fluid is transferred through successive contact between the housing and the screw flights from one thread to the next.   Geometries can vary.   Screw pumps provide a specific volume with each cycle and can be dependable in metering applications.   The geometries of the single or multiple screws and the drive speed will affect the pumping action required.   The capacity of screw pumps can be calculated based on the dimensions of the pump, the dimensions of the surface of the screws, and the rotational speed of the rotor since a specific volume is transferred with each revolution.   In applications where multiple rotors are used, the load is divided between a number of rotating screws.   The casing acts as the stator when two or more rotors are used.   Based upon the needs of the application, timed or untimed rotors may be chosen. Untimed rotors are simpler in design.   The combination of factors relating to the drive speed, flow, and the characteristics of the fluid transferred may affect the flow rate and volume fed through each cavity. In water and wastewater treatment applications, a less viscous solution will require a lower power drive compared to untreated sewage, excess sludge, or concentrated slurries, which may require a higher power motor.   The viscosity of the fluid transferred and the lift required may affect the speed and power required.   Indicators of pump malfunction include decrease in flow rate or increased noise. The efficiency of screw pumps requires that each rotor turns at a rate that allows each cavity to fill completely in order to work at full capacity.   Theory Screw pumps are a unique type of rotary positive displacement pump in which the flow through the pumping elements is truly axial. The liquid is carried between the screw threads on one or more rotors. The liquid is then displaced axially as the screws rotate and mesh. In other types of rotary pumps, the liquid is forced to travel circumferentially, however the screw pump has an axial flow pattern and low internal velocities. It provides a number of advantages in many applications where liquid agitation or churning is objectionable. Screw pumps are classified as two different types: the single rotor and the multiple rotor. The multiple rotor is further divided into timed and untimed categories. Timed rotors rely on outside means for phasing the mesh of the threads and for supporting the forces acting on the rotors. Untimed rotors rely on precision and accuracy of the screw forms for proper mesh and transmission of rotation (Fraser, et. al., 1986.). History: The screw pump is the oldest type of pump. The first applications, dating back to the third century B.C., included irrigation and land drainage. The screw pump is thought to have been first used in Egypt (Ewbank, 1972). After several other types of pumps were invented, the screw pump was not used as much because these other pumps could handle higher head capacities. However, later it was found that these pumps could not handle wastewater like the screw pump could. Because of this, the screw pump became widely used for such an application. The Dutch were the first to design a spiral lift screw in 1955. After this, double screw units were put into operation for flood control in the Netherlands and in municipal sewage installations in Europe. Based on excellent results from the pumps used in Europe, the trend extended to Canada and United States and are currently used today (Cheremisinoff, et. al., 1992) [2]. How a Screw Pump Works: Screw pumps for power transmission systems are generally used only on submarines. Although low in efficiency and expensive, the screw pump is suitable for high   pressures   (3000   psi),   and delivers   Ã‚  fluid   Ã‚  with   Ã‚  little   Ã‚  noise   Ã‚  or   Ã‚  pressure pulsation. Screw   pumps   are   available   in   several   different designs;   however,   they   all   operate   in   a   similar manner.   In   a   fixed-displacement   rotary-type   screw pump (fig. 1, view A), fluid is propelled axially in   a   constant,   uniform   flow   through   the   action of just three moving parts-a power rotor and two idler   rotors.   The   power   rotor   is   the   only   driven element,   extending   outside   the   pump   casing   for power   connections   to   an   electrical   motor.   The idler  rotors   are   turned   by   the   power   rotor   throu gh the   Ã‚  action   Ã‚  of   Ã‚  the   Ã‚  meshing   Ã‚  threads.   Ã‚  The   Ã‚  fluid pumped   between   the   meshing   helical   threads   of the idler and power rotors provides a protective film to prevent metal-to-metal contact. The idler rotors   perform   no   work;   therefore,   they   do   not need to be connected by gears to transmit power. The   enclosures   formed   by   the   meshing   of   the rotors inside the close clearance housing contain the fluid being pumped. As the rotors turn, these enclosures   move   axially,   providing   a   continuous flow.   Effective performance   is   based   on   the following   Ã‚  factors: The rolling action obtained with the thread design   of   the   rotors   is   responsible   for   the   very quiet pump operation. The symmetrical pressure loading   around   the   power   rotor   eliminates   the need   for   radial   bearings   because   there   are   no radial   loads.   The   cartridge-type   ball   bearing   in   the pump   positions   the   power   rotor   for   proper   seal operation.   The   axial   loads   on   the   rotors   created by discharge pressure are hydraulically balanced. The key to screw pump performance is the operation   of   the   idler   rotors   in   their   housing bores. The idler rotors generate a hydrodynamic film   to   support   themselves   in   their   bores   like journal bearings. Since this film is self-generated, it   depends   on   three   operating   characteristics   of the   pump-speed,   discharge   pressure,   and   fluid viscosity. The strength of the film is increased by increasing   the   operating   speed,   by   decreasing pressure, or by increasing the fluid viscosity. This is why screw pump performance capabilities are based   on   pump   speed,   discharge   pressure,   and fluid   viscosity. The supply line is connected at the center of the pump housing in some pumps (fig. 1, view B).   Fluid   enters   into   the   pumps   suction   port, which   opens   into   chambers   at   the   ends   of   the screw assembly. As the screws turn, the fluid flows between the threads at each end of the assembly. The   threads   carry   the   fluid   along   within   the housing   toward   the   center   of   the   pump to the discharge port [1]. Three Basic Types : Single Screw The single screw pump is more commonly known as the Archimedean screw. It is quite large; typical dimensions include a diameter of 12 inches or greater, and a length up to about 50 feet. It is normally used as a water-raising pump with the screw arranged at an angle of 30 degrees. It can also be used for handling liquids containing solids in suspension with either vertical lift or horizontal transport. The design of single screw pumps allows very little fracturing of particles and little abrasion damage to the pump. One disadvantage is the considerable bulk necessary to achieve high capacities since rotational speeds are of the order of 30-60 rpm (Warring, 1984) [5]. Intermeshing Screw Pump The intermeshing screw pump is commonly called a rigid-screw pump. This type of pump is suitable for a wide range of sizes, and can be run at high speeds. The larger screw pumps are used for bulk handling of oils and similar fluids. The basic type is suitable for handling most clean fluids with low flow velocities and at low heads (Warring, 1984)[5]. Eccentric screw pump The eccentric screw pump is versatile. It is capable of handling a variety of liquids and products with high efficiency. It comprises of a rigid screw form rotor rolling in a resilient internal helical stator of hard or soft rubber with a moderately eccentric motion. It can handle viscous liquids, slurries, pastes, solids in suspension, and delicate products. This is because of the low flow velocities through the pump (Warring, 1984)[5]. Applications: There are several applications of the screw pump that include a wide range of markets: utilities fuel oil service, industrial oil burners, lubricating oil service, chemical processes, petroleum and crude oil industries, power hydraulics, and many others (Fraser, et. al., 1986). Listed below are some typical situations where a screw pump is used. The benefits of using a screw pump in each of these situations are discussed (Cheremisinoff, et. al., 1992)[2]. Raw sewage lift stations: Can handle variety of raw sewage influent, are non-clogging, require little attention, are resistant to motor overloads, and are not affected by running dry Sewage plant lift stations: Used for sewage lifts up to 40 feet and have self-regulating lift capacity (Normal lifts are 30 feet, while high lifts are 40 feet high.) Return activated sludge: Little floc disintegration, nonturbulent discharge into effluent channel, low horsepower requirements, improved activated sludge treatment. Stormwater pumping: Are ideal because of large capacity at low heads, no prescreening necessary Land Drainage: Used for flood control, can pump large volumes of water over levees. Capacity : The delivered capacity of any screw pump is the theoretical capacity minus the internal leakage. In order to find the capacity of a screw pump the speed of the pump must be known. The delivered capacity of any rotary screw pump can be increased several different ways. The capacity can be increased by simply increasing the speed, increasing the viscosity, or decreasing the differential pressure. The capacity of the pump depends on several factors (Cheremisinoff, et. al., 1992)[2]: Diameter of the screw Speed of the screw Number of flights mounted on the screw shaft Flights: Single, double, and triple flights are often used. Flights are also known as helixes. With each increase in flights, there is a 20% increase in capacity. Therefore, a single flight pump has a capacity that is 80% of a double flight pump, which in turn has a capacity that is 80% of a triple flight capacity. The three-flight pump can handle the most capacity in the least amount of space. Angle of inclination of the screw The greater the angle of inclination, the lower the output. The output lowers approximately 3% for every degree increase over a 22 inclination. Level of influent in the influent chamber Ratio of the diameter of the screw shaft to the outside diameter of the screw flights Clearance between screw flights and trough Advantages : Wide range of flows and pressures Wide range of liquids and viscosities Built-in variable capacity High speed capability allowing freedom of driver selection Low internal velocities Self-priming with good suction characteristics High tolerance for entrained air and other gases Minimum churning or foaming Low mechanical vibration, pulsation-free flow, and quiet operation Rugged, compact design easy to install and maintain High tolerance to contamination in comparison with other rotary pumps (Fraser, et. al., 1986)[4]. Disadvantages : Relatively high cost because of close tolerances and running clearances Performance characteristics sensitive to viscosity change High pressure capability requires long pumping elements (Fraser, et. al., 1986)[4]. Characteristics and Efficiency of Screw Pumps: The screw pump has a number of very important advantages compared with centrifugal due to recovery of velocity head at the discharge pumps. In order, however, to appreciate fully pipe are not as great, what the screw pump will do as compared with the centrifugal pump, particularly for low head operation, it is necessary to have a thorough knowledge of the characteristic curves of both types of pumps. The three curves which are reproduced here show an actual comparison between a screw pump and a 36-in. centrifugal pump. A great deal of care has been taken to make this comparison as fair as possible; but owing to the dissimilarity of the characteristics of the two pumps, a perfect comparison is practically impossible. For this reason , wherever it is impossible to make the conditions coincide exactly for the two different pumps, the centrifugal pump has been given every advantage, yet even under rather severe handicaps, the screw still maintains its supremacy under low head conditions. The combined curve shown in Fig. 3 illustrates that at all heads lower than 12.6 ft. the screw pump is the more efficient of the two pumps. It will be noticed that the 42-in. centrifugal has not been compared with the 42-in. screw pump because the screw pumps are designed for such very low heads that the suction and discharge sizes are made larger than the connections for centrifugal pumps which handle the same capacity. In other words, the 42-in. centrifugal pump would have a capacity so much greater than that of the 42-in. screw that comparison would be impossible. All of the total heads which are shown in the three curves are total dynamic heads, and this includes the velocity head. Therefore, the water delivered from the screw pump is moving at a lower velocity because of the size of pipe, and hence it is in a more usable form. The entrance losses of the suction pipe and the losses due to recovery of velocity head at the discharge pipe are not as great. It has often been stated that the speed of a screw pump can be much higher than that of a centrifugal operating under the same conditions. These curves demonstrate this beyond a doubt. It will be noted that the centrifugal pump operates at 224 r.p.m., while the screw pump operates at a speed more than 50 per cent in excess of this, namely, 360 r.p.m. The advantage in the cost and the efficiency of a motor for operating these two pumps is distinctly in favor of the screw pump. Furthermore, the screw pump is a much lighter pump, requiring less expensive foundations, and it is easier to install. The 42-in. screw pump weighs 9,000 pounds, while the 36-in. centrifugal pump weighs 21,000 pounds. This shows that the body of the screw pump is much smaller than that of the centrifugal pump in spite of the fact that the pipe sizes are larger than the latter. In addition to this, the arrangement for pumping over levees, or between canals at different levels, is much more simple for the screw pu mp than for the centrifugal pump. The property through which the canal runs is always long and narrow and the screw pump, together with its prime mover, makes a long narrow installation which lends itself to the shape of the property in which it is to be installed. The centrifugal pump is usually a more costly pump to produce than the screw pump, and this is especially true of the pump with the characteristics shown in Fig. 2 because of the fact that this 36-in. pump has a Francis runner. The Francis runner is known for its efficiency at low heads and in this case the curve reaches the unusually high maximum point of 90 per cent. This is partly due to the special design and partly due to the very careful workmanship and careful testing of the unit in question. The screw pump, on the other hand, had a caststeel runner whose surfaces were only partially smooth. No great effort was made to bring up its point of maximum efficiency, and therefore it does not exceed 76 per cent at any point. Yet, even in the face of these handicaps of workmanship and finish on the particular units which were selected for this comparison, the screw pump is shown to be inherently a more efficient pump at low heads. It does not take a great deal of imagination to see how the screw pump efficiency curve of Fig. 3 would compare with the centrifugal pump efficiency curve had its blades been made of bronze and highly polished so as to reach a maximum point somewhere above 80 per cent. The curves shown in Fig. 3 are out of the ordinary in that they are plotted against the total head rather than against the conventional gallons per minute. This is done because the comparisons are at low heads rather than at a given capacity. By using this method of plotting, it can readily be observed that at low heads the efficiencies of the two pumps can be read directly from the chart. For example, at a head of 6 ft. the efficiency of the screw pump is 57 per cent while that of the centrifugal pump is only 42 per cent. This same information could be taken from the other curves but it would be inconvenient to do so. To get the efficiency from Fig. 1 it is necessary first to read the capacity. At 6 ft. the capacity is approximately 37,000 g.p.m. The efficiency is quite indefinite on account of the steepness of the curve; but it is apparent that it checks approximately with the reading given in Fig. 3; namely, 57 per cent. Also in Fig. 2 it is necessary first to read the capacity and then the efficiency, which checks with Fig. 3 and is 42 per cent. In addition to this, Fig. 1 and Fig. 2 would not make a graphical comparison even if plotted on the same sheet. The important point which should be kept in mind is that these curves may not show up the screw pump to advantage when read in their entirety but that at the extreme right where the points of low working heads exist the advantages of the screw pump begin to assert themselves. It is under these conditions that a screw pump should be used. In general, these curves have demonstrated, directly or indirectly, most of the advantages of the screw pump over the centrifugal as follows: Higher efficiency at low heads, higher speed, lighter weight, smaller dimensions, lower first cost, lower cost of installation, cheaper motor, more efficient motor, low head installation.

A Case Study of the Glass Bangle Industry

The glass manufacturing industry in Ferozabad, Uttar Pradesh, produces bangles, utensils, bulbs, decorative articles etc. The glass industry has been classified as hazardous and the employment of child labour (children below age 14 years) in it is prohibited. However, available research and literature indicated that child labour was concentrated mainly in the production of glass bangles. At the time of the present study over 50,000 children were generally believed to be engaged in the hazardous glass bangle industry of Ferozabad.The process of manufacture of glass bangles is broken down into six separate stages and each stage is done by a separate specialized enterprise. At the first stage, the spring bangles are produced at a glass factory and it involves work at the furnace and handling, coloring, and shaping the molten glass into a spring form or rings. The subsequent processes like straightening, linking up the edges of the glass spirals, joining the edges, hardening them, cuttin g designs into them and coloring the bangles are done in separate stages by small informal sector enterprises using different tools like kerosene lamps, abrasive wheel, mud oven, and chemical colors for each of the processes.Unlike glass factories, these small informal sector enterprises are not registered and difficult to observe as they are often located inside households and in small alleys. Moreover, the Child Labour (Prohibition and Regulation) Act of 1986 does not cover the informal sector.OBJECTIVES AND METHODOLOGYThe study aimed to document the extent of child labour, types of activities in which children are engaged, employment conditions , and the cost implications of eliminating child labour. Data collection involved an enterprise survey. As the production process for glass bangles involves a number of different and distinct stages, enterprises were chosen from individual stages of production to ensure a representative selection. In all 268 enterprises with 4100 workers a nd approximately 1000 child labourers were covered.Anticipating that the information furnished by the employers on child labour and the number of children employed may be misleading or grossly understated, field investigators were trained to distinguish children from adults through observation. As this was still difficult to do for children in the 12-16 age group, investigators were allowed to record their observation in either of the three categories ‘definitely adult’, ‘definitely child’, or ‘probably child’. The category of ‘probably child’ was used when an investigator could not decide if a worker was a child.KEY FINDINGSThe total number of child labourers employed in the glass bangle industry was estimated on the basis of the number of children employed in different stages of production. Of the approximately 60,000 workers in the glass bangle industry, 9,40011,000 are children constituting about 16 to 19 percent of the workfor ce in this industry. Employment of children was confined  mostly to unskilled jobs like carrying and sorting in the glass factories. Within the stages of production where several different activities are performed, children do the least skilled of these activities (see table). In other words, children do not have unique or irreplaceable skills and are therefore not necessary for the glass bangles industry.The daily productivity per worker is between 12 to 32 tora (312 or 13 double dozen) bangles per day for different production stages. Children are commonly said by employers to work slower and take longer hours to achieve the same output as their adult counterparts. Each enterprise is paid on a piece rate basis. The wage payment system has a very strict control of the output.Teams of workers must achieve a prescribed minimum level of output in order to be given the agreed daily payment, and it often takes more than eight hours to achieve this minimum acceptable output. Since child ren are said to work slower than adults, they generally need to work longer hours than Working conditions & Health hazards adults in order to achieve the same output and therefore As ‘carriers’: the same daily income. carrying molten glass from the furnace to the Working spaces are small and cramped. Burns and respiratory problems are common occupational health hazards (see box). Several young males and adults were observed without the thumb or forefinger. Tuberculosis is a very common health problem in Ferozabad.Payments to child labourers are estimated to account for only about 15 percent of the total labour cost and so about 4 to 7 percent of the cost of producing a glass bangle. shaper or loom maker, constant exposure to the heat, sound and pollution. Straightening: work in closed rooms, no cross ventilation and are continuously exposed to smoke emitted from dozens of kerosene lamps. Joining and cutting: long hours of sitting in one posture, risk of cramps; continuo us exposure to smoke from the  kerosene lamps.Colouring: high toxic effect of chemical-based colours, handled with bare hands; colours stick to the fingers and palms and are difficult to remove. The increase in the cost of production of one dozen bangles (as most consumers buy bangles by the Hardening: dozen) as a result of elimination of child labour was working around a small furnace and hot trays; calculated in three different ways based on three burns are common. different assumptions.If a sufficient  number of adult workers from the large labour reserve in India are available and willing to work at the present, market determined wage rate , there would be no cost effect, as adults would replace children at the same piece rate payment. Assumptions 2 and 3 presuppose that adult workers would need to be paid a higher wage (10 and 20 percent, respectively) in order to attract the additional adult workers required to replace the child workers. In that case, production costs go u p by only about 2-3 paise a dozen for plain bangles and 6-12 paise for coloured and detailed cut bangles.In percentage terms, this would mean only a 0, 2 and 4 percent increase in the cost of glass bangles in all three scenarios. Even at the retail level (which we assume has a 200 percent mark-up compared to wholesale), the cost of a dozen glass bangles would go up by only 10-20 paise for plain bangles and 12-27 paise for coloured and detailed cut bangles. There is no economic  justification to employ child labour in the glass bangle industry, as children do not occupy a necessary role in the glass bangle production, nor do they have the skills that could not replaced by adults, and elimination of child labour would increase the cost of production only marginally.RECOMMENDATIONSImprove production technology and work environment of the glass bangle industry. In the shortrun, the health of those children who continue to work would improve. In the long run, the demand for child labou r should decrease as the increased capital investments made would create a need for more skilled and responsible adult workers. The number of adult labourers interested in doing this work should increase along with improvement in working conditions and increased wages resulting from the need for greater skills and responsibility. Thus it will have a favourable impact on the goal of eliminating child labour.

Apple’s “1984”: Greatest Commercial Ever Made Essay

â€Å"1984† is an American television commercial which introduced the Apple Macintosh personal computer for the first time. The commercial served as a significant milestone in the history of adverting and had a massive effect on the popularity of Apple. The ad consistently been lauded as a classic, winning critical acclaim over time. It is now considered a watershed event and a masterpiece in advertising, and is widely regarded as one of the most memorable and successful American television commercials of all time. It aired only once on daytime television, on 22 January 1984 in the third quarter of Super Bowl XVIII. The ad was not only rated as the best advertisement ever in 2007, it was also rated as the ‘Best Super Bowl spot in the 40 years history’. The turning point event was not the only computer advertisement that aired in these years, but it was â€Å"the only one that changed people’s lives†. The ad started the phenomenon known as â€Å"event marketing,† in which a high-visibility commercial garners a lot of extra free publicity. â€Å"1984† also inaugurated the trend of showcasing commercials on the Super Bowl. And, most importantly for Apple, the ad brought consumers into the stores. The commercial opens with a droning voice resonating through a science-fiction dystrophic setting, which is held in dark, blue and gray tones. Then you see emotionless, bald and almost robotic people marching in unanimity through a long tunnel with telescreens on the wall. Then out of nowhere, a young woman appears, dressed like an athlete, in a color-full sports outfit that forms a strong contrast to the dull gray environment surrounding her. She carries a sledgehammer and is being chased by uniformed guards and then she runs up to the screen, hurls a hammer with a heroic grunt, and shatters the TV image of the said dictator named â€Å"Big Brother†. As the screen explodes, bathing the stunned audience in the light of freedom, a voice-over announces, â€Å"On January 24th, Apple Computer will introduce the Macintosh. And you’ll see why 1984 won’t be like â€Å"1984.† The ad was an allusion to George Orwell’s noted novel, â€Å"Nineteen Eighty-Four†, which described a dystopian future ruled by a televised â€Å"Big Brother†. After the ad was released in 1984, Apple became a household name in the United States. Apple’s 1984 commercial’s aim was to brand their product, Macintosh with an ideology of empowerment and individuality; contrary to the 1970s perception that personal computers were tools invented for utilitarian purposes and designed to facilitate specific tasks. During those times, the trend was common and utilitarian, so with Macintosh deviating its image against the norm, the people’s attention was acquired with a bold ad set up by Apple. The 1984 ad’s strategy was to differentiate themselves by combating conformity and asserting individuality. It was a definite plus for Apple to choose to air the commercial during the most watched television event in United States, The Super Bowl. Surely, the amount of people watching was at an all-time high thus making the visibility of the commercial reach its maximum. With a large number of people exposed to the memorable commercial, it is more likely to be remembered and talked about, thus making the Macintosh known and popular. Apple’s strategy of making the viewers of the Super Bowl, particularly a wide range of age, gender, ethnicity and social status as their target audience was a clever move since the more exposure, the better outcome. The commercial made a bold move in referencing George Orwell’s novel â€Å"Nineteen Eighty- Four† which could easily been misinterpreted and ended up scaring the audience with futuristic dystopian themes. Fortunately, the ad was considered as revolutionary, innovative and positively shocking which is a good thing because it made the idea of Apple stick into people’s minds. With Apple imaging itself as the ‘hero’/’saviour’ of the masses against forced conformity, the commercial was a clever way of saying that ‘If you buy a Mac, the awful dystopian future will not take place and instead individuality and self-empowerment will dominate.’ Ever since that commercial, the Mac has glowed with an aura of rebellion and empowerment. One major element on why the ad was so successful was, of course, the remarkable production values. Nobody had ever spent that much money to make a commercial look like a big-budget blockbuster movie. By bringing in the best people in the industry, the execution was astounding especially to the common individual. Steve Job’s vision of stressing the liberating power of the Apple Macintosh and paving the way for individuality was highlighted as the message of the commercial. The advertisement delivered the message of what Apple as a whole stood for and what distinguished it from the multitude of other computer brands in the market. Steve Jobs thought he knew what was special about Apple: they were the underdogs, who’d battled the corporate giants and brought computing power to the masses. The 1984 ad glorified the Information Age into a good vs. evil battle between technologies. They considered the rival PC in the market as bad technology – centralized, authoritarian – which crushes the human freedom and controls peoples’ minds. But we can be liberated from that bad technology by the good technology – independent, individualized – of the Apple Mac. In that instant when â€Å"1984† premiered, it positioned the Apple brand as creative, different and human while re-positioning its competition as staid, status quo and robotic. The commercial ultimately explained Apple’s philosophy and purpose; that people, not just government and big corporations, should run technology. If computers aren’t to take over our lives, they have to be accessible.
