Polyesters: Characteristics and Applications

Polyesters: Characteristics and Applications Scrunch it, wash it without any wear and wrinkles. Thats what polyester became famous for. Polyester was the fabric of choice in a changing economy of speed, efficiency and convenience. If the food industry produced fries and coke, the textile industry supplemented it with Polyester quick, cheap and easy. It was W.H. Carothers who discovered that alcohols and carboxyl acids could be successfully mixed to create fibers. Carothers was working for duPont at the time and unfortunately when he discovered Nylon, polyester took a back seat. PET Terylene Carothers incomplete research had not advanced to investigating the polyester formed from mixing ethylene glycol and terephthalic acid. It was British scientists Whinfield and Dickson who patented PET or PETE in 1941. Polyethylene terephthalate forms the basis for synthetic fibers like Dacron, Terylene and polyester. Later that year, the first polyester fiber Terylene was created by Whinfield and Dickson along with Birtwhistle and Ritchiethey. Terylene was first manufactured by Imperial Chemical Industries or ICI. DuPonts Role It was in 1946 that duPont bought all legal rights from ICI. In 1950, the Dealware property of duPont manufactured another polyester fiber, which they named Dacron. Mylar was introduced in 1952. Polyester was first introduced to the American public in 1951 as the magical fabric that needed no ironing! PET and PEN are duPont trademarks that have turned the use and consumption of Polyester around. Polyester Becomes Popular Subsequent to the development of Terylene and Dacron, Kodel was developed by Eastman Chemical Products, Inc in 1958. The polyester market underwent rapid expansion and textile mills emerged everywhere. Many of the mills were located at small gas stations and produced cheap polyester apparel. The inexpensive and durable fiber became very popular and the industry expanded rapidly till the 1970s. Unfortunately, the infamous double-knit polyester image hit the industry and polyester soon came to be known as the uncomfortable fabric. The Phoenix Rises Today, polyester is largely regarded as a cheap fabric that is rather uncomfortable for sensitive human skin to wear. However, the emergence of luxury fibers like polyester microfiber and various polyester blends the industry is experiencing resurgence. The Tennessee Eastman Company and the Man-Made Fiber Producers Associations (MMFPA) Polyester Fashion Council played a significant role in the revival of polyester. The Tennessee Eastman Company started a YES campaign for polYESter and popularized it via radio and television. The idea was to focus on the wash and go properties of polyester rather than sell it as a cheap fabric. Hoechst Fibers Industries also played a part. They conducted various studies from 1981 to 1983 and found that 89% of people could not distinguish between polyester and other natural fibers like cotton, wool and silk. Also, it was found that people were more interested in the appearance of the apparel than the fabric it was made of. Today, the biggest contributor to the appeal of polyester is the discovery of microfibers. Microfibers give polyester the feel of silk and are rapidly becoming the choice of fabric. With an expensive tag to match, the cheap image of polyester seems to be on its way out. Heres to heralding a new era in the history of polyester! Polyester is a term often defined as long-chain polymers chemically composed of at least 85% by weight of an ester and a dihydric alcohol and a terephthalic acid. In other words, it means the linking of several esters within the fibers. Reaction of alcohol with carboxylic acid results in the formation of esters. Polyester also refers to the various polymers in which the backbones are formed by the esterification condensation of polyfunctional alcohols and acids. Polyester can also be classified as saturated and unsaturated polyesters. Saturated polyesters refer to that family of polyesters in which the polyester backbones are saturated. They are thus not as reactive as unsaturated polyesters. They consist of low molecular weight liquids used as plasticizers and as reactants in forming urethane polymers, and linear, high molecular weight thermoplastics such as polyethylene terephthalate (Dacron and Mylar). Usual reactants for the saturated polyesters are a glycol and an acid or anhydride. Unsaturated polyesters refer to that family of polyesters in which the backbone consists of alkyl thermosetting resins characterized by vinyl unsaturation. They are mostly used in reinforced plastics. These are the most widely used and economical family of resins. Characteristics of polyester Polyester fabrics and fibers are extremely strong. Polyester is very durable: resistant to most chemicals, stretching and shrinking, wrinkle resistant, mildew and abrasion resistant. Polyester is hydrophobic in nature and quick drying. It can be used for insulation by manufacturing hollow fibers. Polyester retains its shape and hence is good for making outdoor clothing for harsh climates. It is easily washed and dried. Uses of Polyester The most popular and one of the earliest uses of polyester was to make polyester suits all the rage in the 70s. Polyester clothes were very popular. Due to its strength and tenacity polyester was also used to make ropes in industries. PET bottles are today one of the most popular uses of polyester. Polyester care tips Taking care of polyester clothing is really easy and very time efficient. Polyester clothing can be machine washed and dried. Adding a fabric softener generally helps. Dry the fabric at low temperatures to get maximum usage from the clothing. Though polyester does not require much ironing, if you must then iron warm. Polyester can be dry-cleaned with no hassles. Polyester is the choice of fiber and fabric for many industries. It can be applied to a wide variety of useful purposes. Use of polyester in garments Polyester is used in the manufacturing of all kinds of clothes and home furnishings like bedspreads, sheets, pillows, furniture, carpets and even curtains. The disco clothing of the 70s with all its jazz and flash was made of polyester. Hydrophobic nature: High tenacity and good durability makes polyester the choice of fabric for high stress outdoors use. Polyester is also a strong fiber that is hydrophobic in nature. It is thus ideal for clothing to be used in wet and damp environments. The fabric is also coated with a water-resistant finish and further intensifies the hydrophobic nature. Being the most heavily recycled polymer worldwide, it is also used by climbers. Climbing suits, parkas, sleeping bags and other outdoor gear are using the new insulating polyester fiberfill products. One can also do winter windsurfing wearing dry suits lined with polyester fleece. Creating insulation: By creating hollow fibers it is also possible to build insulation into the polyester fiber. Air is trapped inside the fiber, which is then warmed by the heat of the body. This keeps the body warm in cold weather. Another method to build insulation is to use crimped polyester in a fiberfill. The crimp helps keep the warm air in. Polyester is an ideal fabric for this kind of insulation because it retains its shape. Cotton and wool tend to flatten over a period of time and loose the warming effect. Wrinkle resistant: Polyester is also wrinkle resistant and is used very often in everyday clothing like pants, shirts, tops, skirts and suits. Used either by itself or as a blend, it is also stain resistant and hence very popular. Industrial uses of polyester While clothing used to be the most popular use of polyester and which made it a household name worldwide, there are many other uses polyester is put to. PET: The most common use of polyester today is to make the plastic bottles that store our much beloved beverages. Shatterproof and cheap these bottles are an absolute boon to the beverages industry. Mylar: An unusual and little known use of polyester is in the manufacturing of balloons. Not the rubber kind that you use for water balloons but the really pretty decorated ones that are gifted on special occasions. These are made of Mylar a kind of polyester film manufactured by DuPont. The balloons are made of a composite of Mylar and aluminum foil. Miscellaneous: Polyester is also used to manufacture high strength ropes, thread, hoses, sails, floppy disk liners, power belting and much more in industries. Thus, polyester has many uses for homes and industries as well. The process of manufacturing polyester is fascinating. It is an artificial man-made fiber. Polyesters are generally manufactured from petroleum from which the constituent acids and alcohols are derived. There are three steps in the synthesizing of polyester. Condensation Polymerization: When acid and alcohol are reacted in a vacuum at high temperatures it results in condensation polymerization. Once the polymerization has occurred the material is extruded onto a casting trough in the form of a ribbon. Once cool, the ribbon hardens and is cut into chips. Melt-spun Fiber: The chips are dried completely. Hopper reservoirs are then used to melt the chips. A unique feature of polyester is that it is melt-spun fiber. The chips are heated, extruded through spinnerets and cools upon hitting the air. It is then loosely wound around cylinders. Drawing: The fibers consequently formed are hot stretched to about five times their original length. This helps to reduce the fiber width. This fiber is now ready and would into cones as filaments. It can also be crimped and cut into staple lengths as per requirements. Different Types Of Polyester There are several processes that can be carried out on the base polyester fiber. These processes add dimension to the polyester fiber as required for various end uses. Polyester is a bright fiber by nature. However, it can be made dull or semi-dull by adding a delusterant. By changing the shape of the spinneret also, the hand and the strength of the fiber can be changed. Most spinnerets are circular. However, square, oval and bean-shaped fibers are also produced sometimes. Hollow fibers can also be created. Polyester fiber is generally drawn to about five times its original length. However, drawing it out further makes it thinner. This is how the latest microfibers are being manufactured. Dyeing can give desired colors of polyester fiber. Normal polyester fiber is long and smooth. Crimping it can give the fiber more bulk and texture and increase its insulation capabilities. Using Polyester Once the polyester fiber is ready it is used to make filament and spun yarns. The yarns can be blended with other fibers to make various blended fabrics. Polyester and cotton are a popular combination. Wool and rayon are also blended with polyester to make fabrics. Polyesters are long chain synthetic polymers that have ester linkages. Polyester materials are used as fibers, plastics, and films; in composites and elastomers; and as coatings. They are truly versatile materials. In the late 1920s American chemist Wallace Carothers and his research group at DuPont began to investigate the formation of polymers from the reaction of aliphatic di acids (having two acid groups) with diols (having two alcohol groups), in search of materials that would give them fibers. At first they were able to form only syrupy mixtures. But the Carothers group did make polyester fibers. They investigated a wide array of dialcohols, diacids, and w-hydroxy acids for use as starting points. Some of the polyesters that they achieved were solids, but they had rather low melting points and thus were not useful as fiber materials. The lack of success was due to the fact that the researchers had used only aliphatic diacids. In order to form long polymer chains, the reactive groups of the reactants must be present in approximately equal amounts. This is easily achieved via the use of amines and the subsequent formation of amine salts. (Diols do not easily form salts.) Carotherss group un derstood the principle of driving an equilibrium reaction and so sought to remove water from their amine salt mixtures, thus forcing the reaction toward ester formation. For this they developed a so-called molecular still, which involved heating the mixture and applying a vacuum coupled with a cold-finger that allowed evacuated water to condense and be removed from the reaction system. Even with this understanding and lots of hard work, they achieved polymer chains with fewer than 100 repeat units. (See Figure 2.) The DuPont research team turned from the synthesis of polyesters to tackle, more successfully, the synthesis of polyamides. The experience with polyesters was put to use in the making of polyamides. Initial polyester formation actually occurred much earlier and is attributed to Gay Lussac and Thà ©ophile-Jules Pelouze in 1833 and Jà ¶ns Jakob Berzelius in 1847. They did not realize what they had discovered, however, and so moved on to other work. Glyptal polyesters were first produced in 1901 by heating glycerol and phthalic anhydride. (See Figure 3.) Because the secondary hydroxyl is less active than the terminal, primary hydroxyl in glycerol, the initial product formed is a linear polyester. A cross-linked product is produced by further heating through reaction the third alcohol. Related compounds, alkyds, were synthesized by Kienle in the 1920s from trifunctional alcohols and dicarboxylic acids. Unsaturated oils (alcohols and anhydrides containing double bonds) were also reacted with phthalic anhydride, yielding polyesters that contained a double bond, which could be further reacted to produce cross-linked products. The extent of cross-linking or drying depends on the amount of unsaturated oil present. Today, the term alkyd is often used to describe all polyesters produced from the reaction of a diacid or anhydride and a diol or triol resulting in a product that contains a double bond that can be further reacted, giving a cross-linked product. (See Figure 4.) These polyesters are called unsaturated polyesters. They are mainly used in the production of reinforced plastics (composites) and nonreinforced filled products for the marine, automotive, and other industries. These glyptal and alkyd polyesters are useful as coating materials but not for fiber or plastic production. The first commercially available polyesters were made by GE in the 1920s. Called Glyptals à ¢Ã¢â‚¬Å¾Ã‚ ¢ , they were used as sealing waxes. Out of the Glyptalà ¢Ã¢â‚¬Å¾Ã‚ ¢ research came alkyd paints. Although these reactions had low fractional conversions, they formed high molecular weight materials because they had functionalities (i.e., a number of reactive groups on a single reactant) greater than 2, resulting in cross-linking. The heat resistance of Carotherss polyesters was not sufficient to withstand the temperature of the hot ironing process. Expanding on the work of Carothers and his coworkers on polyesters, Whinfield and Dickson, in England, overcame the problems of the Carothers group by using aromatic acids, especially terephthalic. This classic reaction, which produces plastics and fibers that are sold under a variety of tradenames, including Dacron, Fortrel, Trevira, and Terylene, and films sold under a variety of trade names that includes Mylar, is shown in Figure 5. All new plants now use pure acid for this reaction. Methyl alcohol, or methanol, is lower boiling than water (65  ° C compared with 100  ° C) and is thus more easily removed, allowing the reaction to be forced toward polymer formation more easily. Although this poly(aryl ester), produced by Whinfield and Dickson, poly(ethylene terephthalate) or PET, met the specifications for a useful synthetic fiber, because of inferior molding machines and inadequate plastic technology, it was not possible to use it in injection molds. Until more recently PET was not a widely used plastic or film material. Although aromatic polyesters had been successfully synthesized from the reaction of ethylene glycol with various aromatic diacids (almost always terephthalic acid or its ester), commercialization of polyester synthesis awaited an inexpensive source of aromatic diacids. In 1953 an inexpensive process for the separation of the various xylene isomers by crystallization was discovered. The availability of inexpensive xylene isomers enabled the formation of terephthalic acid through the air oxidation of the p-xylene isomer. Du Pont, in 1953, produced polyester fibers from melt spinning, but it was not until the 1970s that these polyester fibers became commercially available. John Travolta and Karen Lynn Gorney in the 1970s hit film Saturday Night Fever. Polyester was a popular fabric used in clothing in the 1970s. In 2000 about 3,900 million pounds of polyester fiber were used in the United States, making it the largest single fiber group material. As with nylon, polyester fibers are comparable to and/or surpass common natural fibers such as cotton and wool in heat stability, wash-and-wear properties, and wrinkle resistance. Textiles blended from polyester, cotton, and wool (in varying combinations) can also be made to be permanent press and wrinkle resistant. The fibers are typically formed from melt or solvent spinning. Chemical and physical modification can generate fibers of differing fiber appearances from the same basic fiber material. Self-crimping textiles are made by combining materials that have differing shrinkage properties. Different shaped dyes produce materials with varying contours and properties, including hollow fibers. Along with the famous polyester suits and slacks, polyester fibers are widely used in undergarments, permanent press shirts, tire cord, and felts. Because the ease of processing and fabricating polyesters is related to the number of methylene groups (-CH 2 -) in the repeat units, scientists turned to the use of diols with additional methylene units. Whereas PET is difficult to mold because of its high melting point, Tm 240 ° C, poly(butylene terephthalate), or PBT, because of its two additional methylene units in the diol-derived portion, is lower melting with a Tg of about 170 ° C. PET also crystallizes relatively slowly, so extra care must be exercised to insure that PET molded products become fully crystallized. Otherwise, the partially crystallized portions will be preferred sites for cracking, crazing, shrinkage, and so on. By comparison, PBT melts at a lower temperature (as noted above), crystallizes more rapidly, and is often employed as a molding compound. PBT has properties that represent a balance between those of nylons and acetals. It is characterized by low moisture absorption, good fatigue resistance, good solvent resistance, extremely good self-lubrication, and good maintenance of its physical properties even at relatively high use temperatures. Fiber-reinforced PBT molding compound is sold under the trade-name Celanex. Another PBT molding compound was first sold under the trade name Valox. Today, there are many PBT molding compounds available. In 2000 worldwide production of PET was 30 million tons. The manufacture of PET textiles is increasing at 5 percent a year, of PET bottles at 10 percent a year. China produces the most polyesters. PET is now used extensively as bottling material for soft drinks instead of glass because it is shatterproof and lightweight. Carbon dioxide permeability decreases with increasing film thickness and crystalline. Glass has better CO 2 impermeability than PET in these respects. Therefore, to achieve optimal crystalline, partially crystalline PET is employed in the stretch blow molding process, carried out to promote further crystalline formation. It is also used for molded automobile parts. Over 500,000 tons of polyester engineering plastics are produced annually in the United States. Polymers are the origin of polyesters Classification of polymers:- Based on characterstics ,intended use and performances of the finished product, polyesters are divided into three main categories:- Plastics, fibres, elastomers. Plastics are widely variety of polymers-based composite materials which possess appreciable me chanical strength (they have stiff chains at room temperature) and are characterised by plasticity,they can be formed or moulded into useful shapes by application of heat andpressure. Materials which possess plasticity at some stage during their formation are also included in this category. Based on their thermal behaviour, plastics have been subdivided into thermoplatics (that soften and flow on heating) and thermosetting or thermohardening plastics (that set or harden on heating) A fibre is any material whose minimum length is 100 times its average diameter which should be less then .25 mm. fibres are natural (cotton, silk, wool) or artficially prepared long chain polymers with average molecular weight of 15000 or more. Fibre forming materials are characterised by high softening or melting points, a high degree of resistence to chemicals and solvents, high tensile strength and very hight rigidity They however undergo irreversible deformation. Elastomers or rubbrs are polyesters characterised by a very high degree of reversible or elastic deformation. They can be stretched to several times their original length but regain their previous shape or dimensions when the streching force is removed. The molecular chains of elastomers can exist in randomly coiled state and their elastic behaviour can be can be compared to that of the spring of a chest expander which uncoils and recoils on application and removal respectively, of an elongated force. The glass-transition temperatures of elastomers are very much below their use temperature. Preparation of polymers:- Bulk polymerization:- a free radical catalyst or initiator is dissolved in the monomer which is then heated and stirred in a suitable vessel. The polymerization n is exothermic and dissipation of heat through cooling ma y be required. As the reaction progresses, the suystem becomes vicious making stirring difficult. The method is economical and the product is of high purity. The technique is used for preapring polyvinyl chloride (PVC) polystyrene (PS) polymethymethacrylate (PMMA). Solution polymerization:- the monomer and catalyst (free radical, cationic and anionic) are dissolved in a suitable inert solvent.  The resulting solution is heated and stirred.  The presence of solvent helps in heat dissipation and in controlling viscosity. The solvent may interact and reduce the molecular wieght of the product whose isolation from the solution is uneconomical unles it is insoluble. The technique is employes where the polymer is to be used in solution form such that as in case of adhesives and surface coatings. Polyacrylonitrile, polyisobutylene and certain block copolymers are produced by this method. Suspension polymerization:- a solution of the catalyst in the monomer is disperse as fine droplets in a n inertsolvent,usually water. To stabilize the suspension, water soluble protective colloids such as polyvinyl alcohol, methyl cellulose or scratch are added and the mixture is kept stirring continuously. The problems of heat dissipation and viscosity increase are absent. The method gives a fairly high molecular weight product in the form of easily separable beads that can be filtered or centrifuged and water washed to remove the protective colloids. The technique is employed for the production of pvc,ps and styrene divinylbenzene copolymer(used for making ion-exchange resins)Emulsion polymerisation:- the particle size of the monomer is reduced to colloidal dimensions by more vigrous stirring and use of synthetic surfactants(aninoic,cationic or non-ionic)in place of protective colloids used in suspension polymerisation.usually water soluble catalysts such as persulphate, hydrogen p eroxide are used.thermal dissipaton and viscosity problems are absent. Both the rate of polymerisation and the molecular weight of the product formed are very high. The product which is in the form of fine particles dispersed in water (called latex) can be used directly as adhesive or an emulsion paint, or it can be isolated by coagulating with an electrolyte. The technique is employed for the industrial production of PVC, PCP, polybutadiene, polyacrylates, polymetyl methacrylate. Melt polycondensation:- The reactants are heated together in exact stochiometry above the melting point of the product, at which temperature the starting materials and product must be thermally stable. Oxygen has to be excluded form the reaction chamber to avoid oxidation at high temperature. Increase in viscosity makes removal of the by-product extremely difficult towards the end (unless high vacuum is applied) which may prevent formation of high molecular weight product. The molten polymer is usually sent directly forspinning, extrision etc. The technique is usually applied for the preparation of polyesters and polyamides. Interfacial polymerization:- The reaction takes place at the interface of between solutions of the recatants in immiscible solvents. increasing the interface by thorough agitation of two solutions substantially the rate of polymerisation. Exact stochiometry is not necessary and a high molecular weight product can be easily formed. Being very simple the method is widely used for the production of polyamides, polyesters, polyurethanes, polysulphonamides. Difference in the reactivity of materials can be utilized to prepare ordered copolymers which otherwise are very difficult to produce. The technique is however limited to reactants having highly reactive functional groups that can readily react at the ambient temperatures. Testing and characterization of polymers:- Testing and characterization of polymeric materials is essential for determining their suitability for a Particular application. The manufactures and processors and need it for quality control such as maintaining product uniformity and for accessing the performance of new material in relation to the existing ones. processors and users wanting to better understand the polymeric behaviors. Under various conditions are naturally interested in knowing their chemical nature. Polymeric materials are very complex in nature. their high molecular weights in homogeneity and their chemical inertness often present difficulties in their identification which therefore requires specific techniques and the use of advanced methods of analysis. The problem of characterstic is further complicated by the market availability of an extermely wide range of materials and the presence of compounding materials such as plastic stablizers and filers (which change the physical propeties of the product) and thus Complete identification of polymeric materials may not always be possible. It is howevere possible to make a positive identification as to the class of polymers (polyeolefine, polyesters, polyamine) to which a given sample belongs. By carrying out some simple test and correlating their results: Application of these tests to the identification of to common polymeric materials is described as:- Physical test:- Physical examination of polymeric materials includes the observation of their color,,solubility,density etc Floatation test:- The test is based on Archimedes principal from which it follows that a material will flow in liquid of same or high density . Combustion test:-holding the pair of tweezers or tongs insert a small piece of the sample into flame of Bunsen burner and ob serve the ease of ignition, flammability of the sample in and out of flame Ph paper test:-take a small amount of powdered sample in a paralysis or ignition tube and place at its open end a piece of moist ph paper holding tube with a clip heat it with Bunsen burner at low heat.

Reality TV Shows in the Arab World

Reality TV Shows in the Arab World Reality TV: the Reality that is Globalized Media Research Methods Arab satellite television stations have recognized themselves now as one of the major sources for information for the Arab world for they are demanding the domination of the American media. Television broadcasting in the Arab world goes back to the mid-1950s when on-governmental air operations were launched in Morocco, Kuwait, and Saudi Arabia. In almost all Arab countries, television services were subordinated to ministries of information or other government bodies, therefore revolving into executive mouthpieces of regime policies as well as into outlets of public civilizing look. By the end of the 1980s, the Arab world TV domination representation began to practice key cracks with the foundation of more independent television organizations in more than a few of Arab countries and the increase of profitable television service besides government spreading. One of the significant developments in the Arab television picture in the 1990s has been the disintegrated of a 40-year government domination representation of broadcasting in the Arab world. The model habitually derives from the idea of broadcasting as a device of public growth that is supposed to be positioned below the government control. In service within ministries of information, television organizations for the majority piece were funded completely from nationwide budgetary allocations and their recruits were viewed as element of state-owned establishment. Moreover, the entry of marketable broadcasters with gigantic technological and monetary possessions into the Arab world television prospect has been a central improvement. In September 1991, Arab audiences had their first experience of confidential satellite television when MBC went on the air from studio services in London with Western-styled indoctrination. More secretive broadcasters followed outfit: Orbit in 1994, ART in 1995, LBC and Future Television in 1995, and Al-Jazeera from Qatar in 1996. The Arab world Television stations had developed too much by the end of the 90s, for the huge and remarkable development era was during 2002 and 2003. The Arab nation since then had decreased the interest in watching news and documentaries, becoming addicted instead to the new trend known as Reality TV. Since 2003 and something new was occurring in the Arab world. Millions of families have closed themselves up in their homes, eyes glued to the TV monitor when the shows begin! The Reality TV had changed several characteristics of the TV broadcast image and content since it occurred, for it is an interesting phenomenon to be focused on to know more about it. Reality TV in the Arab world is built on certain basics which affects the traditions and cultures of the Arabian societies in different ways. 1. The History and The Rise of Reality TV In the past, television programs were built up to be for all family members, however nowadays most of the TV shows and mostly the Reality TV ones are built on the bases of an audience made up of females teenagers and housewives. Reality TV has a historical background that should be focused on in order to know how it arrived to the Arab world countries. Moreover, the rise of reality TV came at a point when networks were in search of a rapid secure way out to financial troubles within the cultural industries. Enlarged expenses in the fabrication of drama, sitcom and comedy ensured unscripted, accepted realistic programming became a feasible financial alternative throughout the 1900s (Hill, 2005). Reality TV has its ancestry in scandalous journalism and popular entertainment, but it owes its supreme money owing to documentary television, which has nearly vanished from television screens in the get up of popular realistic programming. Also, there are three major strands to the progress of popular realistic television, and these relate to three areas of different, and so far overlapping, areas of media fabrication: sensationalist journalism, documentary television, and well-liked entertainment (Biressi Nunn, 2005). The apprehension about reality TV as putting a finish period to documentary includes the claim that modern television or decision about the world that documentary is seen to have occupied, and therefore lacking hope for the setting up of meaning (Bignell, 2005). The quarrel for an apocalyptic finish of television history is reliant on comparing Reality TV to documentarys past but differentiates Reality TV from that past and makes it look like a split growth. Furthermore, Reality TV seems to drift liberated of the past, obtainable in a nonstop present, and therefore looks to its critics like a reckless television type. As an observation of the growth of a live on air television production in the 60s, its obvious that programmers started producing traditional dramatic works of Arab and world literature, but they also started looking at Western shows for either motivation or stealing. By the 80s, the main successes were Arabian versions of primarily European and American shows. In the 90s, it became ordinary for the perception of a Western show, its privileges and invention bible, to be bought and locally reproduced for local use. The rise of Reality TV in the Arab world was in 2003, the program Super Star rapidly became the majority important show of that period. It was broadcasted on Future TV, where by Super Star attempted a clear Pan-Arab explore for the next star singer, by means of casting calls, adjudicators, and live performances, and the audiences right to take part in the ballot. 2. The bases that are built on for the concept of Reality TV The principle of program scheduling is to arrange television performance time donating programs that will lift up ratings at meticulous periods of the day. In a broadcasting ethnicity with several channels, the plan enables channels to contend with each other for audiences by scheduling their programs considering what their competitors will be presenting. Reality TV programs are merely commercial and flourishing if they keep on giving reasons for their expenses and catch the attention of the audience over a comparatively extended run (Escoffery, 2006 ). The guarantee that a long-lasting series has on holding onto the viewers for a period of the programs run which offers the vision of a reliable viewers whose demographic demand and a mass may be eye-catching to advertisers and can lift up the broadcasting channels public profile. Schedulers offer recommendations to commissioning are prepared (Andrejevic, 2004). The last day of December 2003 witnessed the labor of the most successful Arab reality show formed in Lebanon: Star Academy. Following Endemol the production company format for the French version, Star Academys group recognized a grouping of talented Arabs and invited them to participate in the Academy, where they lived and skilled to become star singers. A graduation progression permitted the instructors at the academy to suggest two candidates and the public would vote for one of them to stay in the Academy. Joe Khalil, director and executive producer in several Arabian TV stations for more than 12 years, said in Nov. 23, 2009 that Star Academy extended the restrictions of reality television for the reason of its extraordinary fame and because it represented a complete realization of a promotion and marketing prospective. Possibly the shows major effect, nevertheless, remains its reliable audience faithfulness to both the prime episodes as well as the 24-hour enthusiastic channel. For most of the Reality Shows and especially Star Academy, the concept is based on celebrities and primes for which every Friday there is a celebrity that has to attend the prime and sing with the participants. For commercial purposes and for it to be more popular Rola Saad the executive producer of Star Academy intend to get international celebrities in the same prime collaborating with Arabian Celebrities. For Star Academy rules of participation is to accept living in the same place with people from the opposite sex, and to swim together in the same swimming pool, and to train sports and dancing together, and the most important is to accept to build up love relationships for some participants. For example, Star Academy chose last season Michel Azzi to be in love with Tania Nemer, the crew of Star Academy had discusses this case with Michel whereby he accepted in order to stay till the last prime, and this was what truly happened. 3. The Globalization and the Privacy publicized in the Reality TV Globalization of communication in the second half of the twentieth century was determined by the commercial benefit of United States corporations. Conservative local cultures are believed to be tattered by dependencies on media products, with their helping ideologies resulting from the United States, with the impact of globalizing customer way of life across regions and populations which turn out to be inhibited to get used to its logics and needs, regardless of the need in some of these regions of possessions to contribute with them (Bignell, 2005). What happens in the communication of globalization is a move from opinions for the homogeneity of media customs to opinions for the homogeneity of political financial system of the media, regardless of provincial and neighborhood differences in the intellectual forms which the media receive. The programmers formulate public the dramas of the individual and carry the ideologies of privacy exposed into new interaction with the negotiated meanings they gain from their meticulous local and provincial television contexts. The type of program develops new conceptions of the open and secret spheres and also draws on discourses of body and self those have already been in circulation in such spheres as popular magazine journalism, optional medicinal measures, and lifestyle-interview television programs (Bignell, 2005). The cultural nationality that these programs reply to displays a challenging cooperation between the plan of the perfectibility of the identity and the institutions, socio-economic constraints and networks of domestic and social dealings that limit it. Television programs have been worried with the capability of television to tolerate observation to the varieties of usual peoples lives, and its ability to become a medium for the community exposure of confessions and revelations that seem incapable to be shared with a persons close sphere (Biressi Nunn, 2005). Star Academy is a distinguished case of this style, in which young people are usually paraded on screen and where the issue of how far the contestants will go in their close relations with each other is a big element of their appeal for audiences. Noticeably, the transitional spread of this mixture of the private body and shared moral challenges and tests, is the medium for financial action inasmuch as the television formats occupied are traded supplies, and the appeal of audiences promotes profitable well being for television institutions in a diversity of ways. 4. Audience Perceptions of Reality TV Audiences most of the times consider Reality TV is there so that viewers can see for themselves, and get an unmediated imminent into some phase of life and manners. Audiences are pessimistic about the reality claims of Reality TV programs, set programs beside a range between reality and fiction, and provide the most admiration to what they distinguish as the most truthful programs. Moreover, the incidence at the present time of huge number of Reality TV programs in the schedules has not enlarged viewing hours, so audiences obviously do not rate Reality TV any more than the programs that they have replaced. If Reality TV had a particular position within the audiences, the viewing of Reality TV would be an addition to other viewing time and entire viewing hours might rise. Even though in the television business Reality TV is seen as the newest important tendency, the commissioning of such programs might have more to do with contest over audience contribution and the branding of channel s and audiences, then with an important move in lifestyle of television viewing (Hill, 2005). In addition, the focal point on younger viewers requires a clarification of the traditions in Television studies that have discussed youth audiences and appreciated their defiant attitudes to programs. The creations of television program bands, personalities and rumor have been essential for an extended era. The vulnerable outcome on recent ways of organizing television is that it would end to consist of must-see programs when crowd audience view the same live broadcast at the same time. Star Academy unpredictably became an essential part of many peoples discussions, and viewers contribution was not only with the program and the website but also with the remarks on the program with other viewers and in the media. Rumor was a significant enjoyment for viewers of Star Academy, and it became a convenient subject for discussion about people who viewers felt they knew. The production of viewer chat is expectant and mirrored by talk in Reality TV programs themselves. Television programs are conquered much more than cinema, for example, by people chatting and interacting in common situations, just as life for viewers at home is often centered on these actions. Star Academy consists largely of sequences of discussion among the participants, representing familiar contact and chat which could be then talked about the viewers. The common use of close-up shots of faces in Star Academy reinforces this wisdom of closeness between the viewer and what is publicized on television, an d contributes to an awareness of correspondence between the audiences regular world and the constructed worlds of the plan. This technique of using and experiencing television gives the fantasy of bodily intimacy, and invokes policies of communal contact which require awareness and generate social closeness. 5. Reality TV effect on the Arabian Societies Most of the participants aim in Reality Shows is to become famous, which had become a new phenomenon. Contestants have been constructed as exemplifying a fame culture in which ethos of famous to be famous has triumphed over the concepts of talent and hard work, and they are seen as diminishing victim to the controlling powers of a cruel fame-making mechanism (Escoffery, 2006). Reality TV shows in the Arab World are based on the aspect of emotional recognition among the observer and the protagonists. The Arab channels wont vacillate to split social and ethical borders in order to enlarge earnings. Its obvious to see how the participants symbolize an exceedingly tolerant social cultures and unusual for Arab society. They hug and kiss on live TV. Although most of the viewers agree on the undesirability of such actions, they cant split their eyes away from the screen. The Reality shows get such high ratings that one wonders about present priorities in the Arab world. Some people see it a s an Israeli-American conspiracy, created in order to distract the Arabs from important issues like Iraq and Palestine. Star Academy had made many changes in the concept of Arabian traditions and cultures in which viewers are being inspired by the participants activities. Several conservative families had to remove the LBC channel from their satellite not to let their children to keep on watching Star Academy because they started imitating the participants in the way they dress, communicate with the other sex, and have fun during the breaks time. Moreover, Big Brother Arabia was a 2004 Reality TV show based on the worldwide program Big Brother, in which contestants live in a unique house while competing to win in the end. The show was filmed in Bahrain, aired on MBC 2, and was planned to follow the success of Star Academy, but failed to do so, and instead the show was only aired for 11 days and then got major controversy in the countries it aired in. Big Brother Arabia producers decided to cancel the show, as there were many complaints from viewers. Joe Khalil, a member in the production crew of the program, said in Nov. 23, 2009 that the program had to be canceled because it brought new traditions to the gulf area which is none as a conservative area in the Arab World, because the audience didnt accept the fact that it featured six men and six women living together in one area, despite staying in separate parts of the house. Star Academy and Big Brother showed the women in the Arab World so close to the western Women in the way they dress, dance, and communicate with men. This is what not all of the viewers accept or welcome. Conclusion Reality TV, in the recent years, has become a very famous phenomenon that has influenced the life of viewers in the Arab world. Reality TV shows were based on some theories and techniques in the work process in which these shows were able to change certain thoughts and traditions in the Arab countries. The audience plays an important role in relation with their perception concerning the Reality TV shows. The audiences consider much reality programming to be entertaining rather than informative. These audiences draw on their own personal experience of social interaction to judge the authenticity of the way ordinary people and their behavior on TV. Reality shows works on collapsing the distance that separates those on either side of the screen by enlightening the hope that it really could be you up there on that screen. The democratized adaptation of the star-making machinery goes further than representing its ability to convert real people into celebrities apparently at will. The powe r that the airbrush once exerted over the image is transposed into the record of reality in the form of the power the blade exerts on soft tissue. Television is like religion, is basically a type of social power. Without both people would really begin to consider for themselves and the social communications would break down. Reality TV had been much popular to reach the Arab World, with certain basics built on it had affected the Arabian societies in different ways. Reality TV had arrived to the Arab World after passing by different stages and experiences. All in all, Reality TV had been a main reason for losing privacy in front of the public audience. Lastly, producing reality shows involves a variety of executive, artistic and technological aspects. Reality shows are mostly approved formats that programmers buy for a certain area, such the case of the Arab World. Reality Shows by nature have a huge number of influences, as well as an important profitable section. References: Andrejevic, M. (2004). Reality TV: The Work of Being Watched. (pp.1-23).

William Butler Yeats poem, Leda and the Swan and Fred Chappel’s Narcissus and Echo :: Yeats Leda and the Swan Essays

William Butler Yeats poem, Leda and the Swan and Fred Chappel’s Narcissus and Echo Poets use many different stylistic devices to capture the attention of the reader. After all, who wants to read a boring poem? Many times, it is the opening line that acts as the "hook." What better way to capture someone's attention than to incite emotion with the first word. Some poets use form to their advantage. Perhaps by writing the words out in different shapes, they will create a broader readership. Some poets use symbolism, or structure to benefit their artistic license. I prefer the subtler and less common stylistic devices. Fred Chappel, in "Narcissus and Echo," and William Butler Yeats poem, "Leda and the Swan." use different, yet effective stylistic devices to capture the attention of the reader and hold on to them throughout the entire poem. By echoing the last sound of each line in his poem, Chappel is able to create two separate poetic rhythms. The first is the fundamental poem written about two mythological characters. Narcissus, the first character, was so enthralled with his own beauty that he fell in love with his own reflection in a pond. He, being so brokenhearted that he could never be with his true love (himself), wasted away until all that was left was a beautiful flower. Hence that flower called Narcissus. Echo is the other character in this "tragic" love story. She fell in love with Narcissus. This was before he turned into a flower, of course. She followed him, trying to speak to him but in his vanity he did not notice her. She was heartbroken and withered away until all that was left was her voice to follow him. Hence the echo. It was her voice combined with his reflection that Narcissus fell in love with. After all, who wouldn't want to hear their words echoed back to them by their lover? Chappel uses this story as the base for his poem, which seems to be of Narcissus' love. The difference is that the words that are echoed back are not quite the same as the original. They seem to be almost an ironic look into the shallow nature of this character. In the seventh line, Chappel brings this irony to light when he writes, "teasing playfully the one being. Unbeing" (181), almost as if he is trying to tell Narcissus that his love is a pretense.

Bretton Woods vs. Protest †Which is More Effective in the Fight Agains

Bretton Woods vs. Protest – Which is More Effective in the Fight Against Global Injustice? The highlight of the anti-globalization movements came in 1999, when protesters lined the streets of Seattle, the location of a meeting of the World Trade Organization (WTO). A theme had been building, and it seemed to come to a head at Seattle: wherever the WTO, International Monetary Fund (IMF), or World Bank met, protesters would follow. However, things were not all peaceful, loving, and in the best interest of humanity. Things soon turned ugly, as the streets became filled with smashed windows, overturned dumpsters, and violence in general. Granted, it very well could have been an out-of-control few who ruined the reputation of all, or, for the conspiracy theorists, it could have been corporate plants stuck in the crowd to stir up trouble. Nevertheless, the message from the protesters had gotten across to the general public, but it wasn’t the message they wanted to portray. The side that the public saw was the lawless one. Perhaps the whole format they use - s ticking their head out for a few days (with trouble happening during that short while) and then fading back into cyber space – inevitably leads to a bad reputation (Meadows Internet). The fact of the matter is that an assembly of such a wide variety of outspoken opinions, often times conflicting, is expected to cause trouble. This makes it extremely difficult for protesters to separate themselves from the label of being a group of ‘irresponsible terrorists’ (Internet). With this setup in place, the protesters to date have failed to have a significant influence. Despite their lack of success to date, the question as to whether or not they have the potent... ...

Delivering Moral Messages in Where Are You Going, Where Have You Been a

Delivering Moral Messages in Where Are You Going, Where Have You Been and A Good Man is Hard to Find School shootings, bombings, rape, and murder are words that are commonly seen in newspaper headlines and heard on the morning news. To most people these acts seem like senseless violence. However, writers like Joyce Carol Oates and Flannery O’Connor use these same violent images to deliver a powerful moral message. Their stories â€Å"Where Are You Going, Where Have You Been?† and â€Å"A Good Man is Hard to Find† are very comparable in the lessons that they teach. Joyce Carol Oates’s â€Å"Where Are You Going, Where Have You Been† begins with the introduction of it’s main character, Connie, a fifteen year- old girl. Oates makes Connie’s vanity quiet well know by telling the reader that Connie has the â€Å"habit of craning her neck to glance into mirrors†. Indeed, it is this vanity and Connie’s innocence that places her right in the path of Arnold Friend. Arnold will confirm this by telling Connie that there is nothing else for â€Å"a pretty girl like you but to be sweet and give in.† In fact, critics generally interpret this story as Connie’s initiation into evil. What’s in a name? If you’re talking about one of Joyce Carol Oates’s characters, a name can say a lot. Arnold Friend’s name can be interpreted as â€Å"aren’t no friend† or â€Å"A. Friend† (Johnson 150). Either way his is a demonic figure that represents the death of Connie’s spirit. In fact, Arnold Friend is based on a serial killer know as â€Å"The Pied Piper of Tucson.† As Oates reports, this â€Å"tabloid psychopath† specialized in â€Å"the seduction and occasional murder of teenage girls† (Wesley). The Pied Piper was in his thirties; yet, he managed to counterfeit teenage dress, talk, and behavior. He also stuffed rags into his leather boots to give him height. These elements of the Pied Piper’s behavior are very obvious in Oates’s portrayal of Arnold Friend (Johnson 148). Joyce Carol Oates dedicated â€Å"Where Are You Going, Where Have You Been† to Bob Dylan. His song â€Å"It’s All Over Now, Baby Blue† was her inspiration. The many lines from Dylan’s song obviously influenced the story (see appendix A). The vagabond who’s rapping at your door Is standing in clothes that you once wore. However, the mood and tone of the story also reveal more subtle connections (Davidson). â€Å"Where Are You Going, Where Have You Been† has ... ... and The Misfit play similar demonic roles and serve as a reminder that evil can come in many forms. They both violently lead their victims to make religious epiphanies. The price paid for their spiritual rebirth is an immediate death. Both Flannery O’Connor and Joyce Carol Oates have been criticized for their violent writings. However, the acts portrayed in their stories aren’t senseless. They are meant to show the purification of the involved characters. Also, they serve as a catharsis or reassurance of faith for the reader. Works Cited Davidson, Rob.

For Using Irregular Verbs Understand the Problem

R U L E S For Using Irregular Verbs Understand the problem. All verbs, whether regular or irregular, have five forms [often called principal parts]. These forms are the infinitive, simple present, simple past, past participle, and present participle. The difference between a regular and an irregular verb is the formation of the simple past and past participle. Regular verbs are dependably consistent—the simple past ends in ed as does the past participle. Check out this chart. Infinitive to laugh to start to wash to wink Simple Present laugh(s) start(s) wash(es) wink(s) Simple Past laughed started washed winked Past Participle laughed started washed winked Present Participle laughing starting washing winking Irregular verbs, on the other hand, can end in a variety of ways, with absolutely no consistent pattern. Here are some examples: Infinitive to drive to feel to put to swim Simple Present drive(s) feel(s) put(s) swim(s) Simple Past drove felt put swam Past Participle driven felt put swum Present Participle driving feeling putting swimming Writers make two frequent errors with irregular verbs: either adding an incorrect ed to the end of an irregular verb or accidentally interchanging the simple past and past participle. Read this sentence: Olivia feeled like exercising yesterday, so she putted on her bathing suit and drived to the YMCA, where she swum so far that only an extra large pepperoni pizza would satisfy her hunger. What are the problems with this sentence? First, feeled should be felt. Next, putted needs to be put. The correct past tense form of drive is drove. And we must change swum to swam. Know the solution. To avoid making mistakes with irregular verbs, learn the very long chart below. Infinitive to arise to awake to be to bear to beat to become to begin to bend to bet to bid (to offer) to bid (to command) to bind to bite to blow to break to bring to build to burst to buy to cast to catch to choose to cling o come to cost to creep to cut to deal to dig to dive to do to draw to drink to drive to eat to fall to feed to feel to fight to find to flee Simple Present arise(s) awake(s)

teaching torn tearing told telling thought thinking thrown throwing understood understanding waked or woken waking Infinitive to wear to wring to write Simple Present wear(s) wring(s) write(s) Simple Past wore wrung wrote Past Participle worn wrung written Present Participle wearing wringing writing In addition to learning the chart above, you must also understand the difference between the simple past and past participle. A simple past tense verb always has just one part. You need no auxiliary verb to form this tense. Look at these examples: Because dinner time was near, my dog Oreo bit the spine of Moby Dick and pulled the novel off of my lap. Because Denise had ignored bills for so long, she wrote out checks for an hour straight. Despite the noise, jolts, and jerks, Alex slept so soundly on the city bus that he missed his stop. Many multipart verbs, however, require the past participle after one or more auxiliary verbs. Read these sentences: Raymond had bitten into the muffin before Charise mentioned that it was her infamous chocolate-broccoli variety. had = auxiliary verb; bitten = past participle Once Woody has written his essay for Mr. Stover, he plans to reward himself with a packet of Twinkies. has = auxiliary verb; written = past participle Cynthia might have slept better if she hadn't watched The Nightmare on Elm Street marathon on HBO. ight, have = auxiliary verbs; slept = past participle For regular verbs, knowing the distinction between the simple past and past participle is unnecessary because both are identical. Check out these two sentences: Diane giggled as her beagle Reliable pushed his cold wet nose into her stomach, searching for cookie crumbs. giggled = simple past Until the disapproving Mrs . Wittman elbowed Latoya in the ribs, the young girl had giggled without stop at the toilet paper streamer attached to Principal Clemens’s shoe. ad = auxiliary verb; giggled = past participle When you choose an irregular verb for a sentence, however, the simple past and past participle are often different, so you must know the distinction. Here are two examples: Essie drove so cautiously that traffic piled up behind her, causing angry drivers to honk their horns and shout obscenities. drove = simple past Essie might have driven faster if she hadn't forgotten her glasses and saw more than big colored blurs through the windshield. might, have = auxiliary verbs; driven = past participle In addition, past participles can function as adjectives in sentences, describing other words. When you use a past participle in this manner, you must choose the correct form. Read these sentences: The calculus exams given by Dr. Ribley are so difficult that his students believe their brains will burst. Delores discovered the stolen bologna under the sofa, guarded fiercely by Max, her Chihuahua. The written reprimand so shamed poor Pablo that he promised his boss never to throw another scoop of ice cream at a customer again. Remember that you can always consult a dictionary when you have a question about the correct form of an irregular verb. Â ©1997 – 2010 by Robin L. Simmons All Rights Reserved.

Intel Company Analysis

Today, Intel is used in many personal computers and lab-tops. The company has made a brand for itself and has been able to sustain ranks among many notable competitors. Today, Intel holds greater than 80 percent of the microprocessors market because of the success of its Pentium chip (Semiconductor 1). This report contains information pertaining to the Intel Company from the beginning and up to 2001. As many computer chip companies Intel had battles being at the top of the competitor’s lists, as well as producing products worth individual attention. This report will give a background of the company, an industry analysis that will explain Intel’s top competitors in detail, a SWOT analysis, a financial analysis and will conclude with suggestions that can help the company grow further. The Intel Corporation began in 1968. Two men are named the founder’s of this company; Robert Noyce, Gordon Moore. Originally, Noyce and Moore wanted to name the company â€Å"Moore Noyce† after their names but realized it sounded like â€Å"more noise† and was not a suitable name for a computer chip company. The company was then named Intel for â€Å"integrated technology. The early focus of the company was on integrated circuit memory devices. One of the first tasks encountered by Intel was producing a DRAM (dynamic random access memory) with a lower price. In 1970, the 1103 was produced. The 1103 was the world’s first 1-kilobyte DRAM. This undercut prices and had increased performance while being smaller. By 1972 the 1103 was the bestselling semiconductor memory chip in the world and the first commercial computer available was the HP 9800 series. Intel was able to gain market share at this time and this allowed them to continue researching and developing new products. However, by 1978 Intel was a full generation behind the Japanese when it came to the 16K DRAM and by 1984 Intel’s total share in DRAMs was barely 1%. The EPROM was produced and it allowed easy programming and gave users the capability to erase memory with ultraviolet light. It was not until Intel decided to raise the prices of the EPROM technology that it made money and in 1984 the EPROM was Intel’s â€Å"money maker. † The microprocessor was invented in 1971 and at that time Intel did not see the potential to use it for personal computers. The 4004 microprocessor was primarily used in calculators but in 1974 the 8080 microprocessor became the standard and Intel became the Industry leader in 8- bit market (Intel 1). Then in 1980, Intel’s 8088 microprocessor was teamed with IBM’s first Personal Computer. This gave Intel a large competitive advantage. Grove stated: â€Å"The presence of IBM in the early ‘80s was crucial. By winning that contract, we won the whole industry design. † This led to the development of the 80386, the first 32-bit processor in 1985. The 386 was an instant success and at that time Intel also decided to sole-produce and stop sourcing to AMD. This led to an eight year legal battle that was eventually negotiated in 1995. To continue gaining competitive advantage Intel moved into other markets. In 1998 Intel begins moving into digital photography, video, networking equipment and Internet commerce markets by manufacturing special chips (Intel 1). However, by 2001 Intel announced it was going remain focused on microchips. At that time Intel had a clear competitive advantage over the microchip market. The SIC code for Intel is 3674 for semiconductors and related devices. The NAICS code is 334413 for semiconductor and related device manufacturing. The semiconductor industry is very cyclical. For instance, in the year 1995 sales grew 40% and were up to $150 billion but in 2001sales fell sharply to $139 billion (Semiconductor 1). In order for Intel to gain and maintain market share they needed to have unique success factors. There are many key success factors for Intel. Intel started with innovators. Noyce and Moore were able to take chances and risks that caused a very successful company. These two were also good managers. They made few mistakes and really took advantage of all their employees. They placed their employees as a top priority and stressed openness, innovativeness and responsibility (Carmichael 1). Intel Corporations top competitors are Texas Instruments, AMD, and Motorola. Texas Instrument started in 1930 by Dr. Clarence Karcher and Eugene McDermott. It started as a Geophysical service that had a unique way of using seismology to explore oil. In order to keep their equipment out of sight from competitors they hired J. Erik Johnson. The company made headway by teaming with the military and in 1961 TI invents the first computer with a silicon integrated base for the Airforce. Then, in 1967 TI invented the first hand-held calculator. Texas instruments have a variety of products from clocks to digital signal processors. Texas Instrument’s main competitive advantage over Intel is calculators. While Intel’s focus was personal computers, Texas Instruments was dominating calculators and the education campaign. AMD Corporation is a company similar to Intel. During the early years AMD and Intel worked together to produce quality products. AMD began in 1969 by founder Jerry Sanders. In 1982, IBM had AMD sign as a second source to Intel for their manufacturing (AMD 1). It was clear that these companies were competing to have the competitive advantage over each other. Another semiconductor company in the industry is Motorola. Motorola began in the 1920s by Paul Galvin. In 1993 Motorola was ranked third of the world’s semiconductor manufacturers (Semiconductor 1). During the early years Motorola had a communication focus. There first product was a battery eliminator that allowed customer’s to use radios without batteries. They began developing pagers and cell phones and their six sigma quality allowed for good competitive advantage. The five forces model helps to draw conclusions about the entire industry. For threats of new entrance the condition is low. In the semiconductor business many companies have patented products. The products produced in this industry are based on innovation. These patents will make it hard for a new entrant to join the industry. Another reason the threat of a new entrant is low in this industry is the asset specificity. This industry requires highly specialized technology and most potential entrants will be reluctant to acquire these specialized assets. For these reasons the threat of new entrants in this industry is low. For bargaining power of suppliers the condition is high. The condition is high because there is a significant cost to switch suppliers. An example of this is Intel’s relationship with PC manufacturers. Intel cannot switch manufacturers without expecting a high cost. The bargaining power of customers is associated with the impact that customer’s have on a producing industry. In the industry of Intel the power of customer’s is medium to low. In this industry the producer’s supply a critical portion of buyer’s input. Intel is the producer in this instance. They are supplying a crucial piece to the buyer and the buyer needs to be willing to pay the price for the piece of equipment. However, to have a competitive advantage in this industry there needs to be some bargaining power to the customers. Maintaining a reasonable price compared to other competitors is very important so the buyer’s keep coming back. In any industry there is going to be a threat of substitutes. In the industry of Intel the threat of substitutes is medium. Competitors in this industry are always going to try and invent the best processor that all individuals will eventually need. However, because of the number of patents and copyrights in this industry substituting other firm inventions become difficult. The last condition facing industries according to the five forces model is rivalry. In this industry the rivalry condition is high. There are many reasons it can be said that the rivalry is high in this industry. For one, the exit barriers are high. Even if the firm is unprofitable at a certain time the cost to exit the industry forces the firm to compete and stay in the industry. Second, high fixed costs in this industry intensify rivalry. The fight for market share in this industry is high because firms must fight to sell the large quantities in production. Another reason of high rivalry in this industry is the number of firms. With the large number of firms competing the rivalry increases because each firm wants to gain market share. Intel as a company can be looked at more in depth by a SWOT analysis. This analysis focuses on strengths, weaknesses, opportunities and threats to the company. Intel has many strengths. One strength is their strong market position and brand name. The company started out with nothing and has become one of the best microprocessor companies. Advanced technology capabilities are also strength to the Intel Company. Without these advance technologies Intel would not be a successful company. The innovative technologies are at the core of the company. Another strength of Intel is their strategic alliances and partnerships. â€Å"The company has partnerships with major players including Asustek Computer, Comstar, Cisco, Fujitsu, IBM, Microsoft, Micron Technology, Sun Microsystems, Sprint,Verizon, and Yahoo! (Datamonitor). These partnership have enabled Intel to produce very significant projects. Also, partnering limits competition in the market. Without worrying about what the other company is going to come out with next, partnering allows for both companies to work together to come up with a great product Some weaknesses of the Intel company include their lack of customer concentration. Intel is a micro processing manufacturing comp any so the number of customer’s consuming the products is low. Intel has high dependence on these customers which reduces bargaining power. Not being able to reduce prices quickly can also hurt Intel. With Intel, reducing prices for customer’s quickly could hurt other areas of production which could lead to dissatisfaction in other areas. The response to customers is seen as weakness because in order to have a competitor advantage appealing to the customer is crucial. There are many opportunities for Intel as a company. Proposing acquisitions could broaden Intel’s portfolio and help them gain competitive advantage in the market. Intel could also grow in the global and PC market. â€Å"Intel offers products including microprocessors and related chipsets designed for the notebook and netbook market segments. Moreover, the company's Atom processor for these segments is very prominent with growing demand. Growing PC market will contribute to steady revenue flows for the company in near term (Datamonitor 11). † The last part of the SWOT analysis is the threats a company has. Increasing competition is a threat to Intel. When Intel’s competitors succeed in producing something a customer wants before them, Intel could run the risk of losing market share or position. No company wants to lose market share to another competitor. In Intel’s industry there is always a threat that another company will produce something at greater speed. Another threat to Intel is litigations and the regulatory commission. In the past Intel was investigated for alleged unfair business transactions, and alleged security failure. Future occurrences of these event will harm Intel’s reputation and investor reputation. The financial ratios and graphs can be found on the attached pages. The first analysis to look at is profitability. The net margin was used in calculating these numbers. By the graph you can see that Intel’s margin was the most profitable in the time periods 1999-2001. When a company has a high profit margin it means that they are selling their products at higher premiums. The graph shows that Intel sold its products at the highest premium. The next analysis estimates liquidity. Liquidity is the ability for a company to be able to meet there near term obligations. The current ratio was used in calculating these numbers. A firm wants a current ratio greater than one. If a firm has a current ratio greater than one it means that they are able to satisfy their near term liabilities. If a firm has a current ratio less than one it means the firm could have a liquidity issue. The graph shows all the companies were able to maintain a liquidity higher than one except Motorola in 2000. The next financial analysis was looking at leverage. The debt-to-equity ratio was used to determine how leveraged Intel and the competitor companies were. The debt-to-equity compares the companies liabilities to their equity. Companies want to have a lower percentage because that means they are using lower leverage and have a stronger equity position. From the graph it is apparent that Intel has the best leverage because of the lower percentage rates. The results shows that Motorola has a very low equity position because there liabilities outweigh there equities. The other two companies, AMD and Texas Instruments seem to be decreasing there liability numbers over time and in the coming years may have a better equity position. The last financial analysis estimate efficiency. The inventory turnover ratio was used to estimate these numbers. The inventory ratio tells you how often a company moves or sells inventory. To predict if a company has a good inventory turnover it is helpful to look at competitor’s results. In the graph included in the attachments, it can be observed that in 1999 and 2000 Intel had the second highest inventory turnover. This means that it took longer for Intel to sell inventories than Texas Instruments or Motorola at that time. However, in the year 2001 it had the lowest inventory turnover. In order to obtain a long lasting company these recommendations could help the company. Some immediate recommendations that should take place in 90 days or less could be to obtain ideas from employees to improve the company or how to gain competitive advantage. Listening to individuals that work for the company may help gain new ideas. Intel prides itself on the innovativeness their employees and it is important to give them a say in how they think the company is doing or where they think it can improve. Another immediate recommendation is a new marketing campaign to seek computer users to switch to Intel processors as opposed to competitors. I think it is important for consumer’s to understand the difference between core processors (such as Intel and AMD) not just the difference in the actual computer (like Dell and Apple). The average American does not know the difference and educating these individuals will help Intel gain a competitor advantage. Short term recommendations could include a price-reducing analysis. If the company could find ways to lower the prices of manufacturing they can gain competitive advantage. Also a short-term recommendation could be to research more about the cellular and wireless industry to see if it would be worth it to the company to branch out further form micro processors. Long term recommendations expand industry further not just for computer but gain market share in cellular and wireless devices. Intel has been the leader of microprocessors for many years. If they can use their knowledge Intel could expand .
