Women and the Law - Essay Example Furthermore, Section 2 of the Street Offences Act 1959 provides that where a woman is cautioned by a constable, in respect of her conduct in a street or public place, that if she persists in such conduct it may result in her being charged with an offence under section one of the Act, the woman, within fourteen clear days afterwards, must apply to a magistrates' court for an order directing that there is to be no entry made in respect of that caution in any record maintained by the police of those so cautioned and that any such entry already made is to be expunged. The court will make the order unless satisfied that on the occasion when she was cautioned she was loitering or soliciting in a street or public place for the purpose of prostitution. Such application made by a woman shall be by way of complaint against the chief officer of police for the area in which the woman is cautioned or against such officer of police as he may designate for the purpose in relation to that area or an y part of it. On the hearing of such complaint, the procedure shall be the same as if it were a complaint by the police officer against the woman. But unless the woman desires that the proceedings shall be conducted in public, an application will be heard and determined in camera. In the case of DPP v Bull,1 the trial court ruled that a male prostitute cannot be a common prostitute within the meaning of the Street Offences Act 1959 s. 1(1). Defendant was charged with being a common prostitute under the Street Offences Act 1959 s. 1(1). The magistrates' court dismissed the information against him on the ground that there was no case to answer since the section applied only to female prostitutes. The matter was appealed by way of case stated, contending that the language of the statute was not gender specific. On appeal, it was held that a male prostitute cannot be a common prostitute within the meaning of s. 1(1) which makes it an offence for a common prostitute to loiter or solicit in a street or public place for the purposes of prostitution since that section applies only to female prostitutes: R. v De Munck (Augusta) [1918] 1 K.B. 635 CCA. Thus, Topaz' conduct in operating as a prostitute on the corner of Boulsdon Street may expose her to a possible charge of soliciting or loitering for purposes of prostitution. It is noteworthy that landlady Rose may be prosecuted for brothel keeping and exploitation of prostitution. Under sections 33 of the Sexual Offences Act 1956 and 33A (as inserted by the Sexual Offences Act 2003) it is an offence to keep a brothel. "Keeping" includes managing or assisting in the management of the brothel. Also, the Sexual Offences Act 2003 makes it an offence for anyone to cause or incite a person to become a prostitute in any part of the world (section 52). Further, it is an offence

Thomson air - Essay Example In addition, two core competitors of Thomson recorded a 17 percent figure of passengers that travelled within Europe. Currently, Thomson administers charges for all the bags that their security team checks. This charge applies for bags that weigh not more than 23 kilograms. Besides, Thomson services possess convenient services such as onboard drink and food menu. It services entail online shopping and eatery. These are coupled with complimentary blankets and pillows for extra comfort in the seats. Additionally, Thomson services entail provision of chocolate and champagne programs. In terms of planes, the airline employs wide body fleet planes. Their flights involve the use of long-haul schedules to limited destinations. The flights extend up to west of Faro and east of Athens. The company possesses plans to move away from this low market share. To begin with, it possesses a plan to eliminate the charge of the first bag as long as it weighs less than twenty three kilograms. This will accord the airline an edge over its competitors since the rivals, Easyjet and Ryanair, charge a fee above the current rate of Thomson. In addition, the company seeks to attract a larger customer base by using e-ticket advertising and airport printed tickets. This will require the use of software engineers in integrating the system with other operations of Thomson. Furthermore, the company has a strategy of expanding its customer base by opening up more destinations. This strategy will be directed towards popular destinations in France, Netherlands, Germany and Switzerland. The product concept rides on the idea that consumers would profess a preference towards quality products. In this perspective, it would be vital to examine how Thomson Company will try to manipulate the quality of its products. The company has made strategies to cut down on its value addition services such as

Advantages And Disadvantages Of Tablets In Pharmaceutical Industry

Advantages And Disadvantages Of Tablets In Pharmaceutical Industry Introduction Tablets are solid dosage forms usually containing active pharmaceutical ingredient and excipients in powder, crystalline or granular form with or without diluents which is prepared either by moulding or compression process. They are solid, biconvex or flat in shape and vary in size, shape and weight which is depends on the medicaments which are used for preparation. They are also varying in hardness, disintegration; dissolution characteristics and thickness depend on their intended use and method of manufacture. Tablets are the most widely used solid dosage forms because of their advantages and popularity increasing day by day. Tablet usually contains filler, diluents, binders, lubricants, glidants, disintegrants, antiadherent, colouring agents and flavouring agents as excipients.[Ansels Pharmaceutical Dosage Forms and Drug Delivery Systems, Eighth Edition, Loyd V. Allen, Jr, Nicholos G. Popovich, Howard C. Ansel, 2005, pp-228-245] Advantages of tablets Unit dosage forms with accurate, stable dose and great precision and least variability. Most stable with respect to physical, chemical and microbiological attributes. Cheapest oral dosage form, easy to handle, use and carry out with attractive and elegant appearance. Cheap, easy to swallow and production does not require and additional processing steps. Provide protection of medicaments from atmospheric conditions like air, moisture and light, etc. Provide prolonged stability to medicaments. Low manufacturing cost as compare to other solid dosage forms and large scale production is possible. Administration of minute dose of drug in accurate amount. Unpleasant taste can be masked by sugar coating. Easy to divide into halves and quarters whenever fraction dose is required. Formulate as a special release products such as enteric or delayed release products. Packing and production is cheap and does not require more space for storage. Disadvantages of tablets Drugs which are amorphous and low density character are difficult to compress into tablet. Hygroscopic drugs are not suitable for compressed tablets. Drugs with low or poor water solubility, sloe dissolution, high absorbance in GI tract may be difficult to formulate. Sensitive to oxygen drugs may require special coating. Cost of production may be increase because of coating and encapsulation to remove bitter and unpleasant taste. Some tablet may cause problem in bioavailability. Difficult to formulate liquid in tablet and swallowing is difficult especially for children and ill patients. Types of tablets There are many types of tablets according to the intended of use and manufacturing process. [A] Oral tablet intended for ingestion Compressed tablets: Tablets can be made by compression of one or more active pharmaceutical ingredient with excipients by basic methods of tablet manufacturing. These types of tablets usually intended to provide raid drug release and disintegration. Tablets are coated after compression. Multiple compressed tablets: Multiple compressed tablets are prepared by compressing the material more than once. These are known as multiple layered tablets or tablet within tablet. Layered are depends on number of fills. Layered tablets are prepared by compaction of fill material in die followed by additional of fill material and compression. Delayed action or Enteric coated tablets: These types of tablets contain a coating which resist dissolution of tablets in Gastro Intestinal Track (GIT) and disintegrate in intestinal fluids thus rendering delayed release features. Enteric coating is generally apply when drug substance is unstable in gastric fluid and may destroyed or may cause irritation in gastric mucosa or to extent absorption of drug from intestine. Normally coating materials mixed with acid and acid functionality or modified natural polymers. Most commonly used coating polymers are: Cellulose acetate phthalate (CAP), polyvinyl acetate phthalate (PVAP) and hydroxyl propyl methyl cellulose phthalate. Sugar coated tablet: Compressed tablets may be coated with coloured or uncoloured sugar coating and the coater is water soluble and dissolve quickly after swallowing. Sugar coat protects drug from environment, remove bitter taste and odour, enhance the appearance of tablet and permit identifying information. Sugar coating has some disadvantages like increase coat of production, require expertise for coating, increase size and weight. Film coated tablets: Tablets are compressed with a thin layer of polymer which forms a skin like film over tablet. The film is usually coloured, more durable and less bulky. The coating is designed to rupture and expose of tablet at desired location within GIT. Most commonly used polymers are Hydroxy propyl cellulose, Hydroxy ethyl and propyl methyl cellulose. Chewable tablet: These types of tablets have smooth surface, creamy base and usually flavoured and coloured mannitol, rapid disintegration which allow dissolving quickly in mouth. These types mostly useful for administration of large dose to children and adults. [B]Tablet used for oral cavity Buccal tablets and sublingual tablets: Buccal and sublingual tablets are flat in shape and intended to dissolve drug in buccal cavity or beneath the tongue for mucosa absorption. These techniques useful for drugs which are destroyed by gastric fluid or poor absorption in GIT. Buccal tablets erode slowly and sublingual tablets dissolve quickly and produce rapid effect. Troches and Lozenges: They are intended to slowly dissolution mostly for local effect but sometimes for systemic absorption. Troches and Lozenges are disc shaped which contain active ingredient and flavouring agent in hard candy or sugar base. Dental cones: dental cones are designed to place in the empty socket for prevention of bacterial growth and sometime bleeding by containing coagulant. Dental cones release slowly for long duration. [C] Tablets for other routes Vaginal tablet: Vaginal tablets are prepared by compression and shaped to fit snugly on plastic inserter devices in uncoated bullet shaped or ovoid tablets which are inserted into vagina for local effects with slow dissolution. They contain anti bacterial effect and also called vaginal inserts. Implantation tablet: Implantation tablets are injected under the skin by giving a small surgical cut into the skin. A special injector a hallow needle and plunger may require for administration. Purpose of these tablets is to prolong drug effect from month to year. These tablets are implanted intramuscularly or subcutaneous so they must be sterile and packed in sterile container. [Pharmaceutics I, P.V. KASTURE, S.R. PARAKH, S.A. HASAN, S.B. GOKHALE, June 2008, pp-14-7,21] [D] Tablets for solution Effervescent tablet: Effervescent tablets prepared by compression of granular salts which release in contact with water. Dispensing tablets: These types of tablets are no longer use because they had dangerous potential. They might be termed compounding tablets because it contain highly potent drug and pharmacist use it for compound prescription. Hypodermic tablets: Hypodermic tablets are soft moulded tablets which contain soluble ingredient and used for extemporaneous parenteral preparation by physician. They are no longer in use because it is difficult to achieve sterility and availability of stable liquid. Tablet triturates: tablet triturates are rarely use now a days because they are obsolete. They are small, cylindrical, molded which contain small amount of potent drug. They must be readily soluble in water and minimum amount pressure require during manufacture. Triturates inserted into capsules or dissolved in liquid to provide accurate potent drug. Tablet Excipients: Excipients are substance other that active ingredient in formulation of tablet. The roles of excipients are to ensure tabletting operation satisfactory and ensure that tablets of specified quality are prepared. Depend on intended use; they are subcategorised in different groups. However excipients affect properties of tablets. Diluents or filler A small amount of powder requires forming suitable size tablet for easy handling. Normally tablet weigh 50mg so some amount of bulk drug requires to incorporation in formulation of tablet which enhance size of tablet. These powders known as diluents or fillers. The ideal dilute should have following properties- cheap, chemically inert, acceptable taste, good compactability and dilution capacity, biocompatible, good biopharmaceutical properties and non hygroscopic. A single substance cannot fulfil all these requirements so different substance have gained use as diluents mainly carbohydrates and inorganic salts sometimes. The most common diluent is lactose because it possess a sires of good properties like dissolves readily in water, has a pleasant taste, non hygroscopic is fairly non reactive and shows good compact ability. Its main limitation is that some people have intolerance to lactose. Basically lactose exists in two forms crystalline and amorphous. Other sugar and sugar alcohols such as glucose, sucrose, and mannitol have been used as alternative fillers, mostly in chewable tablets or lozenges because of their pleasant taste. Other important example of the filler is an inorganic substance, dicalcium phosphate dehydrate. It is insoluble in water and also non hygroscopic but have hydrophilic property i.e. easily wetted by water. It also has good flow ability and therefore it is used mostly in direct compaction. [Michael, Pharmaceutics: the design and manufacture of medicines.- 3rd ed. Edinburgh : Churchill Livingstone, 2007.] [ Leon Lachman, Herbert A. Lieberman and Joseph L. Kanig. (1991). the theory and practise of industrial pharmacy. 3rd addition: Varghese publishing house. Page no. 293- 303.] Disintegrants: According to Michael, 2007, a disintegrant is added in formulation of tablet, which promotes drug dissolution and provide an effective surface area, when comes in contact to liquid and breaks down in small fragments. The process of disintegration for tablet occurs in main two steps [1] Tablet wets by sold and pores it [2] Breaks down of tablet into small fragments which include aggregation of primary particles into small drug particles. Disintegrant suggested in some mechanism such as swelling of particles, wetting reaction, repulsion of particle and particle recovery. Most common types of disintegrants in tablets are maize, potato and corn starch. the concentration of starch is up to 10% required but today normally modified starch or modified cellulose are used which are very high swelling disintegrants. So its requires typically 1-5% by weight which facilitate particle-particle repulsion. However, disintegrants can be mixed with other ingredients such as granules to increase effective disintegration of the tablet into smaller fragments. Leon Lachman et al, 1991, suggested that other group of disintegrants may function by producing gas, normally carbon dioxide, in contact with water. This types of disintegrants used in effervescent tablets and normally not in tablets that should be swallowed as a solid. The liberation of carbon dioxide is achieved by the decomposition of carbonate salts or bicarbonate in contact with acidic water. The acidic pH is obtained by adding citric acid and tartaric acid. [ Michael, Pharmaceutics: the design and manufacture of medicines.- 3rd ed. Edinburgh : Churchill Livingstone, 2007. 3. Leon Lachman, Herbert A. Lieberman and Joseph L. Kanig. (1991). the theory and practise of industrial pharmacy. 3rd addition: Varghese publishing house. Page no. 293- 303] Binder Binder is added to the tablet or filler mixture to ensure that tablets and granules have sufficient mechanical strength. There are several ways to add it in powder- Mixed with powder before wet granulation which completely or partially dissolves during agglomeration process by agglomeration liquid. Mixed with other ingredient as a dry powder solution before compaction process As a solution used as agglomeration liquid during wet granulation. Typically 2-10% of binders or dry binders are used in formulation. Most tradition common binders are starch, sucrose and gelatine but now most common are polyvinylpyrrolidone and cellulose derivatives which have improved adhesive properties. Examples of dry binders are microcrystalline cellulose and crosslinked polyvinylpyrrolidone. Solution binders are most effective therefore it is incorporated in granules. Glidant The role of the Glidant is to improve the flow ability of the powder. Glidants are used in formulation for direct compaction but they are also used in granulation process before tabletting which ensure flow ability of tablet mass for high speed production. Traditionally talc has been used as glidant about 1-2% concentration in formulation but nowadays the most commonly used glidant is colloidal silica added in very low proportion about 0.2% by weight.[ Michael, Pharmaceutics: the design and manufacture of medicines.- 3rd ed. Edinburgh : Churchill Livingstone, 2007. 3. Leon Lachman, Herbert A. Lieberman and Joseph L. Kanig. (1991). the theory and practise of industrial pharmacy. 3rd addition: Varghese publishing house. Page no. 293- 303] Lubricant The function of lubrication is to ensure low lubrication between solid and the die wall during tablet formation and ejection. High friction during tabletting can cause a series of problems such as inadequate tablet quality and may even stop production. Lubrication is most important which included in most of production. Lubrication can get by mainly two mechanism, fluid lubrication and boundary lubrication. In fluid lubrication, liquid is achieved between die surface and tablet surface which separates the moving surfaces of the solids from each other and reduces the friction. While in boundary lubrication, it is considered as a surface phenomenon, as here moving surface is separated by a very thin layer of lubricants. Such boundary lubricants are Stearic acid salts, primarily Magnesium Stearate which is most widely use due to its superior lubrication properties. Besides reducing friction, lubricants may also causes undesirable changes such as reducing tablet strength with bonding between the particles during compaction. Because of hydrophobic properties of lubricants, tablet disintegration and dissolution are often retarded by the addition of lubricants. Thus, minimum amount of lubricants are used, i.e. concentrations of 1% or below, often 0.25-0.5%.in order to avoid these negative effects, more hyd rophilic substances have been suggested as alternatives to the hydrophobic lubricants. For example, surface active agents and polyethylene glycols and sometimes a combination of hydrophilic and hydrophobic substances might also be used. [M. E Aulton, Pharmaceutics, The Science of Dosage Form Design, Second Edition, 2002, pp.408-412] Antiadherent Antiadherent are substance which reduce adhesion between powder and punch faces which prevent sticking of particles to punches. The sticking is mainly affected by moisture content of the powder. Such adherence especially prone to happen if the tablet punches have marking or symbols which lead to a build of thin layer of powder on the punches which in turn will lead to an uneven and matt tablet surface with unclear markings or symbols. Some lubricants such as Magnesium Stearate have also antiadherent properties. However, other substances with limited ability to reduce friction can also act as antiadherent such as talc and starch. [M. E Aulton, Pharmaceutics, The Science of Dosage Form Design, Second Edition, 2002, pp.408-412] Sorbents Sorbents are substances which has capacity to sorbing some quantities of fluid into dry state. So oil and oil-drug solutions can be incorporated into mixture of powder and compacted into tablets. Most commonly used sorbents are Microcrystalline Cellulose and Silica. [M. E Aulton, Pharmaceutics, The Science of Dosage Form Design, Second Edition, 2002, pp.408-412] Flavouring agents Flavouring agents are incorporated into a formulation to remove unpleasant taste of bitter drug or to make tablet more pleasant or mask. This can be achieved by coating or by adding some drug particles. Most of Flavouring agents are thermolabile so it cannot be added in process which involve heating. They are mixed with granules as alcoholic solution. Colouring agents The aim to add colourant is to aid identification of tablet, improve looks of tablet and patient compliance. Mostly, colourant are added during coating of tablet but some of colourant may be added in formulation prior to compaction. Colourant may be added as an insoluble powder or dissolved in granulation liquid and the latter procedure may produce colour variation by migration of soluble dye during drying stage. Method of tablet preparation Three types method of tablet preparation- [1] Direct compression method [2] Wet granulation [3] Dry granulation Direct compression method Some chemicals have free flowing and cohesive properties so they are enable to compress directly in a tablet machine without granulation of it. Some chemicals lacking of these qualities so some excipients like filler, disintegrants agents, lubricants and glidants are used to impart these qualities for production of tablets by direct compression. Figure (A) Steps of direct compression tableting Some precaution must be taken during direct compression to avoid air entrapment which cause capping, splitting, or laminating of tablets. Forced feeders or induced feeders are used to reduce air entrapment, make filling powder more dense and amenable to compaction. Capping also may be caused by punches that are not perfectly clean and flawlessly smooth or by too much fines granulation. Some aged or improperly stored tablets also may exhibit splitting and other physical deformations. Wet granulation Granulation is process in which primary powder particles are made to form large and these types of multi particle called granules. In pharmaceutical industry, granules are useful in production of tablets and capsules in ranges of particle size between0.2 to 0.5mm. Granulation prevents segregation of constituents of powder, improve flow ability of powder, improve compaction characteristics of mixture and reduce toxic dust. Wet granulation is widely used method for production of compressed tablets which include flowing steps- Weighting and blending In this step, specified quantities of active ingredient, diluents or fillers, and disintegrating agents are mixed by mechanical powder blender or mixture until uniform. Most widely used fillers are lactose, microcrystalline cellulose, starch, powdered sucrose, and calcium phosphate. Selections of filler depend on the experience of manufacture, cost and compatibility with formulation. Among the fillers, lactose is most preferred because of its solubility and compatibility, and microcrystalline cellulose, because of its easy compaction compatibility and consistent uniformity of supply. Disintegrating agents include croscarmellose, corn and potato starches, sodium starch glycolate, sodium carboxymethylcellulose, polyvinyl polypyrrolidone (PVP), cation exchange resins, alginic acid and other materials which swell or expand on exposure to moisture and helps to breakup tablets in gastrointestinal track (GIT). Mainly croscarmellose and sodium starch glycolate are used because of their high water uptake and rapid action. Mostly up to 5-10% of starch is suitable for formulation, but up to about 20% may be used to facilitate more rapid tablet disintegration. The total amount of disintegrant is not always used but sometime it added in preparation of granulation and sometime half of it added to tablet formation which called double disintegration of tablet. One portion of disintegrant assist breakup of tablet into pieces and other portion breakup pieces into particles. Preparation of Damp Mass A liquid binder is now added to the powder to facilitate adhesion of powder particles. A damp mass resembling dough is formed and used to prepare the granulation. A good binder is very important for hardness of tablet and does not hinder the release of drug from the tablet. Most widely used binders are povidone, an aqueous preparation of corn starch (10-20%), methyl cellulose (3%), carboxymethylcellulose, and microcrystalline cellulose. Some drugs may be adversely affected by an aqueous binder then non-aqueous solutions or dry binder may be used. The amount of binders is a part of operation which maintains integrity of tablet after compression. However, care must be exercised not to over or underwet powder otherwise underwet can result too hard granules for proper tablet formulation and overwet can result too soft and tend to crumble in under wetting. After getting desired dump mass a colorant or flavorant may be added to prepare a granulation with an added features. Screening Damp Mass into Pellets and Granules The Dump Mass is pressed through 6 or 8 mesh size to prepare granules. This process may be done by hand or by special equipment which prepares granules by extrusion process. The final product are spread on large piece of paper in trays and dried. Drying the granulation Granules may be dried in special drying cabinets which is thermostatically controlled at constantly record the time, temperature and humidity. Fluid bed drier and tray drier are commonly used for during process. Sizing the granulation by Dry Screening After drying, the granules are passed through a screen of a smaller mess than that used to prepare the original granulation. The size of granules depends upon the size of the punches to be used. Usually 12 to 20 mesh sizes are used for granulation. Sizing of the granules is necessary so that the die cavities for tablet compression may be completely or rapidly filled by the free flowing granules. Voids or air spaces left by too large a granulation result in production of uneven tablets. Adding Lubrication and Blending After dry screening, a dry lubricant is spread over the granulation through a fine mess screen which contributes to preparation of compressed tablets. Among the most commonly used lubricants are talc, magnesium stearate, calcium stearate, stearic acid, and sodium stearyl fumarate in ranges of 0.1% to 5%. Lubricants improve flow property of granules form hooper ti die, prevent adhesion during compaction, reduce friction between die and punch and provide a sheen final product. Figure (B) Tablet compression by wet granulation [Pharmaceutics I, P.V. KASTURE, S.R. PARAKH, S.A. HASAN, S.B. GOKHALE, June 2008, pp-14-7, 21] Some special wet granulation techniques High shear mixture granulation Fluid bed granulation Extrusion- spheronisation Spray drying Dry granulation In this method, powder mixer is compressed in large pieces and subsequently broken down or sized into granules. In this method, either active ingredient or diluent must have cohesive properties. This method is basically applied to materials which cannot be prepared by wet granulation because of moisture degradation properties or thermo-mobile properties of granules. It is carried out by two steps: Slugging: After weighing and the mixing of ingredients, the powder mixture is slugged or compressed into large flat tablets about one inch in diameter. Slugs are than broken up hand or mill and passed through a screen of desired mess for sizing and sometimes lubricant are added and prepared by compression. Roller compaction: Instead of slugging, powder compactors may be used to increase the density of a powder by pressing it between rollers at 1 ton to 6 tons of pressure. The compact material is broken up, sized, and lubricated, and tablets are prepared by compression. Commonly used binding agents are methyl cellulose or hydroxylmethyl cellulose (6-12%) which produces good hardness and friability of tablet. Figure (C) Tablet compression by Dry Granulation [Pharmaceutics I, P.V. KASTURE, S.R. PARAKH, S.A. HASAN, S.B. GOKHALE, June 2008, pp-14-7, 21] Tableting of granulation: There are different types of tabletting machines which are used in the productivity but similar in basic function and operation. They all compress tablet formulation within steel die cavity by the pressure exerted by the movement of two steel punches, lower punch and an upper punch. Problems in manufacture of tablet Capping and lamination: Capping means partial and complete separation of the top or bottom crowns of a tablet from main body of a tablet. While lamination is term used to describe the separation of the two or more distinct layers. Some reasons which are responsible for these problems are as follows: Air is entrapped among the particles during the compression process and does not escape until compression pressure is released. Die wall pressure causes enough internal stress to cause a crack which is due to plastic deformation of the particles during compaction. Sometimes due to deep concave or bevelled edge punches. Development of wear ring. This problem can reduced or eliminated by slowing tabletting rate, granules with sufficient moisture, pre-compression, using flat punches, correct adjustment punches. [Porter, S C, 1981, Tablet coating, Drug Cosmetic Indu, May 46, June 44, Aug 40, Sept 50] Weight variation: This is very important in process control measurement. If anything that can alter the die filling process can alter tablet weight, it causes weight variation because the weight of the tablet being compressed is determined by the amount of the granulation in the die prior to compression. Some causes of variation are large granules, poor mixing of granules with lubricants and glidants, poor granulation flow from hopper, double impression and punch variation. Picking Picking is the term used to describe the surface material from tablet that is sticking to being removed from the tablets surface by a punch. It concerns when punching tips have engraving or embossing Sticking Sticking is usually referred to adhesion of tablet material to die wall. Because of that, lower punch cannot move freely and additional force is required to overcome friction between die wall and the tablet. These problems can be solved by design large lettering, adding polishing agent such as colloidal silica or additional lubricants. Some low melting point substances such as polyethylene glycol may also cause sticking at the heat of compression. Such Remedies are addition of high melting point materials and consequently increasing size of tablet. Mottling: Mottling is term used unequal distribution of colour on a tablet with light and dark areas. Its due to colour difference of drug with excipients or drugs whose degradation product is coloured. Such problems might be solved by using colorants but it can cause mottling on the top of surface when granulation undergoes drying. To overcome difficulties, it require to change solvent system, binder system and by reducing temperature. Tablet coating Tablet coating is application of coating of material to the exterior of tablet with some intentional benefits. It is also intended for modified release applications. Main three types of coating are- Film coating Sugar coating Press coating Coating of tablets are for following purposes- [1] Protection from environment, light and moisture [2] To remove bitter taste of some tablets and for easy swallowing of tablets [3] Colour coating mask differences in appearance which effect on patient compliance [4] Rapid identification by manufacturer, pharmacist and patient [5] Functional films can enable sustained and enteric protection [6] Improve looks (elegance), masks and minor difference in raw material appereance [7] Enhance strength, reduce dust and cross contamination Film coating This is more modern and widely used for tablet coating. Most of newly launched coated products are film coated rather than sugar coating. Film coating involves covering of tablet by thin film layer of coating liquid (polymer). Coating liquid is sprayed in a rotating tablet bed or bed fluidised tablet which contains plasticizer, polymer, colourant and solvent. The drying condition permits removal of solvent and leaves a thin layer around each tablet. Sometimes aqueous solution or organic solutions are used to reduce elimination of volatile organic compound, health and safety and cost reduction purposes. Film coating polymer should have following properties- [1] Optimum solubility to facilitate dissolution of final product. High soluble for immediate release and low soluble for controlled release. [2] Optimum viscosity to permit and trouble free spraying of solution. [3] Optimum permeability to optimize shelf life of tablet preparation and some tuned to provide an effective barrier oxygen and water vapour. [4] Good mechanical strength to withstand the impact and abrasion encountered in normal handling which avoids cracks and imperfections. Cellulose derivatives like Hydroxypropylmethylcellulosa (HPMC), methylcellulose, hydroxypropylcellulose (HPC) and Methacrylate amino ester copolymer are available polymer for film coating. Sugar coating Sugar coating involves the successive application of sucrose based solutions to tablet cores in suitable equipment. Some stages in production of sugar coated tablets are- [1] Sealing of tablet core- provide water proofing core from coating process and shellac, cellulose acetate phthalate are normally used in sealing process. [2] Sub coating- it is the actual start of sugar coating which provides necessary build-up to roundup the tablet edge. Bulking agents such as calcium carbonate or talc added in sucrose solution with gum. [3] Smoothing it increases tablet size to predetermined dimension by syrup solution. This solution contains pigments, starch, gelatine, acacia or opacifier. [4] Colouring- dyes or pigments [5] Polishing- tablets need to be polished to achieve final elegance by waxes like beeswax, carnubawax or hard paraffin. [6] Printing Difference between sugar and film coating Press coating Press coating involves compaction of granules material around core of tablet with the use of compressing equipment like Manesty Drycota. Today press coating is used in to separate incompatible placed core and coating layer. This process requires some care and large or irregularly sized agglomerate of granules may cause core to tilt in die. Disadvantages of process arise from complexities of mechanism used in compression equipment. [M. E Aulton, Pharmaceutics, The Sc

Iron Deficiency Anemia Essay examples -- Health Medicine Papers

Iron Deficiency Anemia I. Introduction Iron Deficiency Anemia affects millions of individuals across the world. This disease strikes many more women than men and has harmful effects on all who suffer from this deficiency that causes oxygen-carrying capacity to decrease. The causes can vary amongst different groups, but the aggravating symptoms remain constant. Much of the research on Iron Deficiency Anemia concentrates on not only the treatment of this disease, but also the prevention of it. To attain a better understanding of how to treat this problem, one must clearly know what Iron Deficiency Anemia means, what causes this disease, the effects of it, and finally how to cure it. II. What Is Iron Deficiency Anemia? Iron is a mineral that is found the in hemoglobin of the Red Blood Cells. It facilitates in the transport of oxygen all over the body. Without this mineral, oxygen cannot be carried to its full capacity. 1 out of 10 women and small children have iron deficiencies. Lacking iron causes lethargy and a weakened immune system. Children who do not have an adequate intake of iron put themselves at risk for intellectual developmental problems. However, an iron deficient person is not necessarily anemic. 7.8 million women are iron deficient, while only 3.3 million women are anemic (http://www.mayohealth.org/mayo/9704/iron_def.htm). When the deficiency becomes so severe that the circulating Red Blood Count and the minerals Ht, Hg, and Hem drop below normal, anemia occurs (See Figure 1). The hormone androgen causes men and women to have different normal values of the hemogram (http://www.medstudents.com.br/hemat/hemat4.htm).

Employees tend to already, after so many years of working with one another, tend to formulate certain cliques based on age, race and other characteristics even on education background and experiences.For this position sales manager of F-fiber Optics, I want to make an unbiased decision on who I pick for the right ethical reasons and not based on any of those criteria but based on merit, experience, education and of course legality (citizenship). In reading about all of the candidates that eave applied for the sales manager position, I'd have to say that they all had impeccable short bios, but to me only two stuck out from the group. Would have to pick between Lynn the IT Manager and Karen the Sales Representative.They both have some kn owledge in Fiber Optics and its engineering and also experience in sales. I think although Lynn would be a great candidate for the job, she would have some trouble acculturating to the job because of her lack of speaking English well and trying to assimilate to our American culture. She would have to catch on fast in order to gain more of respective clients. Her short bio did not state if she was single or had a family, so should be possible candidate to be able to Stay late hours to work on certain projects and to gain clients.The next potential client I would lean closely toward is Karen because of her background graduating in Fiber Optic engineering. She would definitely have a lot of experience in the field and had been awarded the Sales Representative of the year award. She has valid experience in selling and captioning people to want to buy a product. I don't think she would have any issues in connecting with potential clients. The job calls for having to stay after 5 P. M.I d on't think Karen with just getting married would have that time to want to spend the extra hours at work. Lynn was a math major and minored in computer analysis and just because she wrote a paper on Fiber Optics doesn't been she is an expert on it. I would ultimately choose Karen the sales rep because she had graduated in the field and I see her possible potential to grow and learn more. She also has experience in sales. I could mold her into how want her to be and this would not only help her but would help me move up the ladder.

Love: Filipino Psychology Essay

Filipino Values for Productivity Values have much to do with the way we act. It is, therefore, important that we understand our Filipino Values. Understanding our own Filipino Values means looking closely into our beliefs, mores, customs, norms, and traditions, examining them closely, looking at their positive and negative polarities, and harnessing the positive polarities of our values as norms of our behavior at work. Our values and norms greatly affected by the several rulers that came on our country. Some norms are inspired by the Spanish rulers; also, some norms are inspired by the Americans, Chinese and Arabs. Thus, with the variety background of our norms, ethical or unethical, we cannot deny the fact that we management to survived from our struggles with the help of our combined norms coming from the different foreign rulers who ruled and help us mold the so called Filipino Values. Even if these values are copied by our ancestors from the different nationality, we tend to claim that these values, combined by the other values we have learned are the values that will consist our own Filipino Values. Values have much to do with the way we act, in the organization, this is truly manifested. As discussed in my first reaction paper, I did presents the strengths of Filipinos in terms of working under an organization. Filipino values for productivity implies the characteristic of Filipinos of hard-work ( masipag at matiyaga). Also, I did present the ability of Filipinos to make use of the little resources available in the workplace. Giving emphasis on the ability of Filipinos of being creativeness depicts a picture of Ma-utak or Madiskarte. Truly Filipinos possessed these strengths but it out weighted by the weaknesses that I will present in this reaction paper. This is from the book of a popular human behavior book author, a Filipino who conducted study in order for him to know the negative values that affect the quality production of Filipinos. Negative values of the Filipinos that affect the quality production are the following: 1. Ningas kugon 2. Bahala na System 3. Baka makalusot Notion 4. May quality controller naman 5. Hindi naman mababawasan sweldo ko 6. Hindi naman malalaman kung sino ang gumagawa ng mali 7. Di na baling ma-reject, may fixer naman 8. Bakit and iba diyan, mas marami pang reject 9. Tahi lang ng tahi 10. Mamaya System. 11. Kahit may reject babayaran pa rin tayo Some of these negative values are mostly seen in a plantation where Filipino workers usually work. To separate the ones that generally manifested even if office and in some other work place, in this reaction paper I will just discuss the necessary values that greatly affect the productivity of us, Filipinos. â€Å"Ningas Kugon ay isang idioma na nangangahulugang sa umpisa lang magaling at kalaunay mag-iiba’t hindi na ipagpapatuloy ang magandang pagsisimula. † To start right and not to continue a good start as you go on to the work. This is a trait that contradicts the essence of hard-work. For Filipinos, first impression is very relevant to build up your image to your boss. Well, this bad, working is not building your image but it is about working to help the organization attain organizational goal. Maybe, you can build up your personal image to your co-employee and boss as your second priority in the organization because I cannot deny the fact that in an organization human relation exist. Doing good from the start will take Juan from humble beginnings to the top if only, he would just continue that good performance from that of the start. The mere point of motivation is being demolished having this kind of trait. This kind of Filipino value is commonly seen in a Campaign Period in an Election. Candidates are here and there, building up and making some name to the people in order for the people to vote for them. In the campaign period they act like he person that could be trusted and the person who will represent them and answer some social problem but when this candidate win and sit in the position, the fairytale is over. In the start, you could see and talk them, but as the time goes by, it will be the opposite. Filipinos are now fighting this kind of situation by which they tend to know the past performance of every candidate and decide who do not have this kind trait. Relating it to productivity, performing good at the start and not continuing that really affects productivity because the product that you will be giving to your customers will be highly observed especially to those customers who are passionately buying your customers. â€Å"Hay nako, nagbago ang lasa ng tinapay nila dati malinamnam ito. † The satisfactory value from the customers is one of the factors that the workers should consider in order to attain success on productivity. â€Å"Ang pagsasawalang-bahala ay isang idioma na nangangahulugan ng pagpapabaya sa isang bagay at iisiping magiging maayos din ang lahat sa bandang huli. † Bahala na means â€Å"I do not care what will happen†. The thought of ‘everything will going to be alright’ also constitutes the this so called Bahala na System. Keep pushing on something that you know it may be not be successful is one of the examples of the bahala na system. Such notion of leaving everything just the way it is and praying that it will going to be okay is the main ideal of this system. For just an example, in a construction project of a bridge, the project team leader knowing that the newly constructed bridge is unstable and not ready to use, but the city government is pushing for its use and then the project team leader let the city government for its use. â€Å"Bahala na, yan ang utos sakin eh†, is the thought of leaving behind the project and not letting yourself be involved in the liabilities. â€Å"Bakit ang iba diyan, mas marami pang mali? † Counting the numbers of your co-worker’s mistakes will not benefit you neither the organization. Filipinos possessed a trait keeps on rotting an organization until it will go down, it is the Crab Mentality. Crab Mentality has to do with the productivity because it one the elements that tend to decrease the average of quality production of Filipino workers. Looking for a loop hole in the personality of your good performing co-employee will is not an act of helping the organization attain its aspired status. Instead of making some rumors about that person, why won’t you make him/her as one of your motivating factor to contribute your efforts to the organization? An exam would be the practice of politicians running for the same position and they present each other’s mistakes and wrong doings in the past to the people. Pulling down those who are trying they best to climb in the ladder of success is one of the Filipino Values that is considered a hindrance on good productivity of the organization. â€Å"Marami pa naming oras, mamaya nalang yan. † Procrastination, this is an act that also, diminishing the essence of hard-work. Filipinos are fan of saying the words – LATER or WAIT FOR A WHILE. We Filipinos have this innate attitude of doing first what is necessary and then doing what you wanted to do. But, having in mind the urgency of the things that needed to be done do not requires a quick action, we tend to postpone it for a while and continue to do the things that you wanted to do. Thinking about when is the deadline of a project and doing the whole project the day before or on the last minute before the submitting hour or day. In the a plantation, procrastination is not observed for the company should produce more than what is demanded in a fixed period of time. Well, in a company producing items this is true, but in an organization running an office giving services, the urgency is observed. Services should always be there, prepared, so when the time comes, if that specific service is needed. In some cases, services that are prepared before an actual demand by the customer is a good quality product. There is this saying by the Filipinos, â€Å"Aanhin pa damo kung patay na ang kabayo†, services or products that are late will result to poor satisfactory feedback from the customers. â€Å"Hindi na baleng ma-reject, may fixer naman na mag-aayos. † Filipinos love on depending everything to something they know that it can help or cure or fix anything they have done wrong or they will do wrong. â€Å"Di bale nalang† means quitting on it or sort of quitting on something and letting it go the way it is. And thinking about the fixer that will easily fix whatever is wrong in the item is the principle of depending on the machine. Instead of making the item in the right manner in order to lessen the use of a fixer machine, Filipinos continue to do the wrong manner of producing the item just meet the deadline. In this point of view you can now see the relationship of procrastination with this trait of depend the item to the machine and to the time of its deadline. With this kind thinking, it manifests the attitude of sacrificing the quality production. The â€Å"Okay na yan† attitude is also one of the elements of this act. Concentrating on quantity and not on the quality of the product is the main thought of this attitude. Filipinos, usually we, as a student would say – â€Å"Okay na yan, basta may maipasa lang† as a â€Å"pampalubag-loob† in not meeting the desired quality of the project or usually in times of examinations. Settling on the quantity produced and not on the quality is not accepted in the organization strictly observing the quality of the products or services being produced. â€Å"Katamaran – ito ay isa sa mga hindi kanaisnais na katangian ng mga Pilipino na kung saan ang mga dapat na gawin ay hindi naisasakatuparan sa kadahilanang nagkukulang and motibo para maigalaw ang kanyang katawan upang magtrabaho’t magbanat ng buto. † To sum up all that is being discussed above, the word laziness is the back bone of such acts and behavior of Filipinos towards productivity. Laziness means not being productive for your organization’s desired status in the future. Lazy, as a song lyric described, it is an act of doing nothing. Laziness is the opposite side of hard-working. Keeping asleep or just lying in your bed could be one of the common acts of laziness. But in the organization, laziness deals about the behaviors of an individual inside the work place showing nothing or no any single accomplishment at all. Laziness is also in line on the idea of not wanting to work inside in the work environment. It indicates the factors of unmotivated or unsatisfied with the management’s way of handling the working conditions they have gone to. Some Filipinos are people who prefer to take a day for a rest and do nothing instead of doing something that are actually to be done on an appropriate time. Some Filipinos tend to do a certain work and as it goes by and by, they will left it unfinished. Some Filipinos work well on the starting period of his job, but eventually take the opportunity to not work effectively in the succeeding time of his job. While some other Filipinos love to depends everything on something that can be the answer for their undertaking. Well, even in any of this behavior you are under, the bottom line will be the picture that depicts Juan, waiting for that ripe guava to fall right into his mouth.

Human Cogntive Architecture Pattern Recognition Essays

Human Cogntive Architecture Pattern Recognition Essays Human Cogntive Architecture Pattern Recognition Essay Human Cogntive Architecture Pattern Recognition Essay Essay Topic: A Very Old Man With Enormous Wings One may be tempted to suppose that we, who experience the world through vision, experience a very different world from the worlds expereinced by bats or dolphins, who rely more on hearing, dogs or rats who make greater use of smell †¦ or spiders or scorpoins who are attuned to mechanical variations. But at sufficiently abstract level, our worlds are all the same three dimensional Euclidean world Roger Shepard (Solso 1994) (73) Visual pattern recognition influences several areas -computer vision, machine learning, robotics, neuroscience, psychology, biological vision, AI, cognitive science, biological perception, visual arts and all aspects of or daily life (object recognition). This paper focuses on visual cognition and pattern recognition; as these influences the human cognitive architecture more than tactile and auditory pattern recognition. Pattern recognition is the key phenomenon in visual cognition it distinguishes human cognitive architecture and bridges top-down and bottom up information processing approach. It also connects inside with outside. Thus connecting human wetware (mind brain complex) to wide-ware of the world. I have used visual arts and illusion to explain pattern recognition because in spite of being abstract and illusive they present interesting good case for schema construction using top-down and bottom up processing. I claim that in pattern recognition top-down processing plays a critical role. This paper is divided into following section: Brain Visual System Complex, Visual Arts, Pattern Recogntion in Non Humans and Instructional implication has been explained using the theories of visual literacy. Brain Visual System Complex Evolutionary story Soslo has depicted 248 million years of organic evolution using 31 day January month of 2000. Insects, dinosaurs, reptiles evolved a well-developed eyes during this period. On January 31 at 11. 59 am human like form appeared and within last 10 minutes falls the entire history if visual arts (Solso 1994) (24). Human eyes are not the most complex visual system the eyes of simple insects are more complex they have many lenses and receptors, while we have just one lens with receptors. Evolutionary biology emphasises that brain and visual system have evolved together as a visual cognitive complex in human. While simple brained animals have complex optical system; it seems complex brain offsets the need of a complex visual system in humans (Solso 1994) (14). Based on Darwinian Evolutionary Theory- human capability to identify, recognise and differential patterns (like dark, from light, blues, from greens, straight lines from curved and moving objects from stationary) has significantly increased the chances of survival. Cognitive psychology elucidates that raw data of sensory signals is meaningless and random. But when these signals fall on a decoding visual system and brain complex they weave a rich pattern of meaningful relation. Most intriguing part is the corresponding, concurrent and complimentary evolution of sensory system, brain and the central nervous system (Solso 1994) (47) Search for meaningful pattern recognition involves at least three parameters: ? What is an object? ? Where is it? ? What is it doing? Pylyshyn elucidates that behind the â€Å"smart† functionality of the visual system is messy yet sophisticated hardware: As the light sensitive surface of the eye are two dimensional, so the sense of depth in visual system comes from the source of information. After ecades of research we now know that part of information of depth comes from the difference between the patterns the two eyes receive. With all our understanding of stereo vision we are still far removed from understanding how does this difference in 2d vision translates to 3d experience? A very small part fovea has sufficient acuity to recognise pattern. Moreover eyes focal length differs for different colours. There is a blind sp ot 10-13 degrees away from fovea. To add the mess the eyes are in constant motion jumping around in rapid saccades several times in each second. Retina our primary contact with the world is not uniform nor it is flat and has uneven distribution of cones rods. Lastly it is continuously smeared with the moving information. However brain builds a uniform, detailed, gapless, 3d-video patterns from the sketchy inputs in the face of such dynamic and impoverished information processing system. Pyhshyn claims strategies like focal attention play a critical role in connecting vision and cognition (Pylyshyn 2003) (5). Evolutionary biology favours the case that top-down processing in pattern recognition is the key distinguishing factor of human architecture. True believers in real patterns Looking at history from twelfth century till date we find philosophers and thinkers instinctively find patterns in chaos right. Plato, Pythogorus, Euclid, Ptolemy, Coprinicus, Newton, Einstein etc all the thinkers have been searching ways to establish order in chaos. It seems that we love to accept linearity, smoothness and stability in the face of the world that is largely unsmooth and random. But are we looking for real patterns and are these patterns inside or they are out side and how do we assign meaning to these patterns. As per Dennett We use folk psychology interpretation of each other as believers, intenders and the like – to predict what people will do next. .. Folk psychology helps us understand and empathise with the others, organise our memories, interpret our emotions and flavour our vision in thousand ways, but the heart of all these is enormous power that predictive folk psychology. Without the predictive power we could not have any interpersonal relations at all; human activity would be just so much like â€Å"Brownian motion† (Dennet 1991) Dennett presents a interesting story which aims to answer the above questions. He claims objective pattern â€Å"pops out† when we view the world through appropriate lenses. Like in the consequence of 2, 4, 6, 8,†¦Ã¢â‚¬ ¦. are different yet when seen through arithmetic lens the exhibit a common pattern add 2 pops out. Similarly intentional stance is the only lens that can help recognise real patterns (Clark 2001) (52-53). Dennett uses an John Conways game of life to highlight real patterns make available potent generalisations and predictions further claims that to miss a pattern is to miss some thing real and explanatory useful, even though every thing that occurs depends on the underlying simple rules (Clark 2001). 52-53) This elaborates the point the intentional stance is crucial for us to believe and attach meaning to pattens. True believers will always believe in real patterns. Intelligence of the human information processing system lies on our capability to recognise, predict and generalise real patterns. Visual Arts: Symbol manipulation Kose in paper summarises the views of these three thinkers. For all symbols gets meaning from convention. Goodman thinks denotation is the primary vehicle for representing. Gardener stresses on specific set of skills in rder to produce or read meaning with a particular symbols system. Cassier emphasis art objects derive meaning from the process of creation for him action and psychology of the artist is the key to understand. I feel representation is the core of cognitive architecture and symbolism is at the core of representation but it is difficult to take reductionist view. It does not seem relevant to elaborate this debate here. However the discussion brings three key concepts to focus: conventionality, specific skill set and artistic/aesthetic experience. All the three points are relevant to process of pattern recognition. Illusion: Limits of Pattern Recognition Solso surmises critical role of experience and top-down approach in view art. The viewing of art causes an immediate conscious experience in people. We see colours, shapes, contours, objects, distances, and interactions (among other things) and, when all of these impressions are sensed, the brain brings meaning and comprehension to the art object. †¦Our mind supplies reasonable inferences to our consciousness about a visual scene, which may be, in fact, absent in the object. We ‘see’ behind occluded objects, feel motion, and react emotionally to provocative themes even though these things may not literally exist. In the cognition of art, our past knowledge supplies consciousness with context. Experience colours art. We understand Picasso’s Guernica, Michelangelo’s, Sistine Chapel, and Rembrandt’s Self-portrait (1658) better because we can feel the intensity of women and children being victimized in the embittered Spanish Civil War, know the Biblical story of creation and man’s fall from grace, and comprehend the weathered features of an old man’s face (Solso 2000). A viewer’s intention in viewing art and personal history strongly influences what he or she looks at in an object. This, in turn, determines which patterns of neural activity are aroused. In addition to situational demands, each person views art with a unique personal history which biases his or her attentional focus - a Nebraska farmer might attend to different features in Grant Wood’s American Gothic than would a New York fashion designer (Solso 2000). E H Gombrich illustrates core of top-down approach and important element of cognitive architecture the guided projection: It is without the support from any structure that the beholder must mobilise his memory of the visible world and project it into the mosaic of strokes and the dabs on the canvas before him. It is here, therefore principle of guided projection reaches its climax. The image, it might be said had no firm anchorage left on the canvas it is only conjured up in our minds. The willing beholder responds to the artist’s suggestions because he enjoys the transformation that occurs in front of his eyes (Gombrich 1986). Artists use various cues to fool the system to activate the relevant schema in viewers mind using top-down processing. When the pattern recognition (perception) departs from the external world, to disagree with the physical reality, it means one is experiencing an illusion. However illusion differs from the truth (Gregory 1997). Pylyshyn starts his book Seeing and Visualising with a honest statement by Galeolio: â€Å"†¦. if the man had been born blind, philosophy would be more perfect, because it would be more perfect, because it would lack many false assumption that have been taken from the sense of sight. † (Pylyshyn 2003) ( Preface) Illusion expose limits or the leaky architecture of two complex structures brain and the visual system. Top-down processing: Pattern recognition of the objects involves knowledge of the world as the sensory data is impoverished and hardly relevant (Gregory 1997). Bottom up Processing: Pattern recognition of the objects uses information from the optic array, which contains sufficient information to guide behaviour. Evolution has produced organisms that are sensitive to the invariants in the optic array and does not require prior knowledge (Gregory 1997). These two approaches cause different type of illusions. Cognitive Illusion due top-down processing resulting in misrepresenting of knowledge. Physical Illusion due to the disturbance of light, between objects and the eyes, are different from illusions due to the disturbance of sensory signals of eye, though both might be classified as ‘physical’. Physical causes: In human vision ‘top-down’ seems to be more important than ‘bottom-up’. This might be because there are more downwards fibres from the cortex to the lateral geniculate bodies LGN ‘relay stations’ than bottom-up from the eyes (Gregory 1997). Classification Visual illusions can provide evidence of object knowledge and working rules for vision, but only when the phenomena are explained and classified (Gregory 1997). A tentative classification is presented, in terms of appearances and kinds of causes in Appendix B (Gregory 1997). Types of illusions: Gregory divides appearances of illusions into classes based on errors of language ambiguities, distortion, paradoxes and fictions. There seems to deeper connection in language and visual system. It kind of connects Chomkys deep structure and surface structures theory. Ambiguities Perception changes while the input from the eyes remain same. A retinal image is infinitely ambiguus which could respond to infinitely possibilities but we see only one (Gregory 1997). Paradox False assumptions creates paradox. Distortions Illusion due to distortion of retinal signals, perspective, brightness, colour. Fictions Suggests fictional forms Opt- Art The pictures are extremely distrubing, Jazzing, moving and generating ghostly shapes (Gregory 1997). Model to understand top-down and bottom-up processing To the ‘bottom-up’ signals and ‘top-down’ knowledge, Gregory adds ‘sideways’ rules. Both top-down and sideways are knowledge. These can be considered as ‘ins-and-outs’ of [pic] Tentative ‘flat box’ of’ vision. As usual, signals from the eyes and the other senses are ‘bottom-up’. Conceptual and perceptual object knowledge are shown in separate ‘top-down’ boxes. Knowledge as embodied in the general rules. is introduced ‘sideways’. Perceptual learning seems to work largely by feedback from behaviour (Gregory 1997). The historical study of systematic misperceptions (illusions), combined with a recent explosion of techniques to measure and stimulate neural activity, has provided a rich source for guiding neurobiological frameworks and experiments to better understand the cognitive architecture (Eagleman 2001). Arts Brain: Search for essentials E. H. Gomrich highlights Plato from Sohpists and makes strong point on the very basis of representation â€Å"that we make a house by the art of building, and by art of painting we make another house, a sort of man-made dreams (pin-ups and comics) produced for those who are awake? † (Gombrich 1986) Zeki claims that like brain visual arts is search for essential. The pre-eminent function of the brain is the acquisition of knowledge about the world around us. Just as brain searches for constancies and essentials, so does art (Zeki 2002) (Preface). .. the artist can find the models that he depicts in his mind, his inner vision, not the external world. When artists try to fool the brain and its record, they can only do so with respect to its stored memory. Even when they don’t know much about the brain, artists were and are aware of the reality of perception and the appearance of the painting (Zeki 2002). V. S. Ramachandran and William Hirstein while explaining Peak Shift Affect take different view, art is a process of selection and amplification of the essentials. The purpose of art, surely, is not merely to depict or represent reality (western art) - for that can be accomplished very easily with a camera- but to enhance, transcend, or indeed even to distort reality. The word ‘rasa’ (might be similar Platonic ideal form) appears repeatedly in Indian art manuals and has no literal translation, but roughly it means ‘the very essence of. ’ So a sculptor in India, for example, might try to portray the rasa of childhood (Plate 2), or the rasa of romantic love, or sexual ecstasy (Plate 3), or feminine grace and perfection (Plate 4). †¦the peak shift effect: If a rat is rewarded for discriminating a rectangle from a square, it will respond even more vigorously to a rectangle that is longer and skinnier that the prototype. An evocative sketch of a female nude may be one which selectively accentuates those feminine form-attributes that allow one to discriminate it from a male figure; Finally, given constraints on allocation of attentional resources, art is most appealing if it produces heightened activity in a single dimension (e. g. through the peak shift principle or through grouping) rather than redundant activation of multiple modules. Consider the way in which a skilled cartoonist produces a caricature of a famous face, say Nixon’s. What he does (unconsciously) is to take the average of all faces, subtract the average from Nixon’s face (to get the difference between Nixon’s face and all others) and then amplify the differences to produce a caricature. The final result, of course, is a drawing that is even more Nixon-like than the original (Hirstein 1999). ADD DIAGRAM 3 A circle represent the loaf of bread (they are round in Viena), a curve added on top will turn into a shopping bag, two little squiggles on its handle will shrink into a purse, now by adding a tail here was a cat (Gombrich 1986). Gombridge uses the simple drawing game to emphasize the power of metamorphosis. Once the tail is added the purse gets destroyed and cat is created; you cannot see the one without obliterating the other. This is simply highlights our capacity to recognise, amplify and generalise a pattern (Gombrich 1986). The way the language of art refers to the visible world is so obvious (due to bottom up processing) and so mysterious (top down processing) that is still largely unknown except to the artists (high-stung on visual schema) themselves who can use it as we use languages – without needing to know its rammar and syntax (Gombrich 1986). So we see Zeki’s focus on Inner Vision, Plato’s emphasis on dream, Ramchandran principle of peak shift affect and Gombridge drawing experiment. All point to the same core function of the brain, using top-down approach to recognise, predict, amplify and generalise the pattern. Schema Development Gombrich in his book Arts and Illusion att empts to address the issue of art universals (schema) and peculiarities (creativity) in artists using science, psychology, and philosophy. Core of his version his is the theory of schemata development and correction. This is derived from the idea that the artist begins not with his visual impression but with his idea or concept and that the artist uses adjusts this idea to fit, as well as it can, the object, landscape, or person before him or her. Gombrich calls this theory making and matching. E H Gombrich while highlighting F. C. Ayers point claims that no artist can imitate reality without schema: The trained drawer acquires a mass of schemata by which he can produce schema of an animal, flower or a house quickly upon the paper. This serves as a support for the representation of his memory images and he gradually modifies the schema until it corresponds to that with which he would express. Many drawers who are deficient in schemata and can draw well from another drawing cannot draw from the object. The dry psychological phenomenon formula correction can tell us a good deal, not only about the essential unit between medieval and post medieval but also of their vital difference. To Middle Ages schema is the image; to post medieval artists, it is the starting point of corrections, adaptation, the means to probe reality and to wrestle with the particular (Gombrich 1986). .. For it is not only the scientists of the stamp of Camper who can examine the schema and test its validity. Since the time Leonardo, at least, every great artist has done the same, consciously, unconsciously. Upto 19th century artist where more like trained drawers and focus was on universal features ideal pattern (schema). However in late 18t h and early 19th Century artists turned against the traditional methods. Gombrige classifies this period as struggle against schema (Gombrich 1986). Gmobridge mentions a statement by Constable who is the centre of the struggle for schemata. Constbale explains elegantly his position in the history of visual arts: I have endeavoured to draw a line between genuine arts (peculiarities or uniqueness) and the mannerism (traditional schemata), but even the greatest painters have never been wholly untainted by manner. Painting is science and should be pursued as the inquiry into the laws of nature. Why, then, may not landscape painting be considered a branch of natural philosophy, of which pictures are but experiments? (Gombrich 1986) Gombridge – To a see patch on a close canvas as a distant mountain is to transform it in according to its meaning. These transformation explain the paradox that world cannot look like a picture, but a picture can look like a world. †¦ it is not the ‘innocent eye’ but the inquiring mind that knows how to probe the ambiguities of vision. Gombrich brings an interesting point to notice- Art is a story of schema creation by trial error and testing. A search for consistencies through anticipation and testing. Bruman and Postman- All cognitive process are represent making a hypothesis (pattern) and matching (pattern) (Gombrich 1986). Nuerological basis for schema in Artist in brain The eye (and other sensory organs) and brain are now thought to be onceptually related. Many theorists suggest that the eye is an extension of the primary visual cortex. Most visual signals follow a well known neurological route (from the retina, to the lateral geniculate bodies, to the primary visual cortex in the occipital lobe) (Solso 2000). The study was conducted on distinguished portrait artists and a novice. The artist selected for this task, HO, is one of Britain’s most. The non-artist used in this study who served as a control subject (AH) was a graduate student in psychology at Stanford University; 32 years old, right handed male with no formal training in art (Solso 2000). Findings: Study suggest two main findings. First they confirm that an area of the brain frequently associated with facial identification was specifically activated. Second, the lower level of activation of the artist indicates that he may be more efficient in the processing of facial features than the novice (Solso 2000). Thus, these two main findings considered together suggest that an expert portrait artist, who frequently sees and draws faces, dedicates relatively less energy to the processing of faces and more to the processing of these features in terms of their associated correlates. In a phrase, the artist thinks portraits more than he ‘sees’ them. Thus we see pattern recognition is more case of schema construction using top-down processing. Aesthetics: Celebration of Pattern recognition: Geyer makes an interesting argument substantiating the point that aesthetic celebration of celebration of our capability of pattern recognition. Geyer highlights Gombrich to state a point that the act of pattern construction is what makes us perceivers rather than mere responders to the stimuli. Lettvin has done close examination of the frogs visual system in his paper â€Å"What the frogs eye tells the frogs brain† Geyers refers to this paper to summarise Frogs visual system: Frogs have four types of visual receptors in the retinas of their eyes. On type responds to large contrast differences, another to changes in contrast, the third to changes in light intensity, and the fourth responds to small, dark, circular objects which are moving toward the frog. This last receptor is called the â€Å"bug detector†, and when it is triggered the automatic response is for the frog’s tongue to shoot out and catch the triggering object (Geyer 1988). The frog does not decide whether it is hungry or even whether the object is a bug, but just shoots out its tongue. All of the frog’s visual processing is â€Å"peripheral, in the retina of the eye. This peripheral sensory apparatus is a rudimentary stimulus/response mechanism, as opposed to our complex, central interpreting system (Geyer 1988). This discussion re-inforces that Frog’s visual system far more complicated than humans while humans brain is far more complicated than Frogs. Concept of focal attention or instinct to search for order/structure and this seems to be unique feature of human eye-brain complex. Geyer claims that while perceiving an aesthetics experience one assumes, predicts and attempts to realize (invent or discover) a existing pattern, when the pattern is actually found the aesthetic inquiry and the experience ends. However, perception in general is a necessary function for human beings, and perception is a process of editing and ordering information from the senses. Thus seeking order is a biologically necessary operation, as essential to our survival as eating and reproducing. Aesthetic experience, as seeking order just for the sake of seeking order, is a celebration of perception. The pleasure in this experience is primal, as it is in eating when hungry and copulating. It is there to encourage a basic need. No wonder evolution has favored perception in the aesthetic phenomenon (Geyer 1988). Neurological basis for aesthetic being a function perceivers processing Using interesting experimental settings Rolf Reber, Nobert Schwarz and Piotr Winkielman propose that aesthetic pleasure is a function of the perceiver’s processing dynamics. They review variables known to influence aesthetic judgments, such as figural goodness, figure–ground contrast, stimulus repetition, symmetry, and prototypicality, and trace their effects to changes in processing fluency. The mail claim is against theories that trace aesthetic pleasure to objective stimulus features per se, they propose that beauty is grounded in the processing experiences of the perceiver, which are in part a function of stimulus properties (Processing Fluency and Aesthetic Pleasure: Is Beauty in the Perceiver’s Processing Experience? (Rolf Reber 2004) Pattern recognition might be the key phenomenon to understand aesthetic phenomenon for what it is. Pattern recognition in Non-human Pattern recognition and object parsing experiments in human the experiments were conducted on humans by XU Carey Welch 1999; Needham Baillergeon 1998 and Spelk in 1993. This experiment conducted on humans was taken as the base to comapre object parsing in adult Rheshus Monkey and human infants. Four experiments are investigating how semi-free-ranging rhesus monkeys form representation of and inferences about visible object presented under natural conditions. Experiments use methods in previous training is required by monkeys. Preferential looking experiments which are common in human infants were used to allows direct comparisons. Experiment displays testing infant’s sensitivity spatiotemporal temporal or featural information (Yuko Munakata 2001). Findings Sensitivity to hands: Humans infants take account of the human hands in analyzing the moti on and objects. However monkeys show no sensitivity to the moving hands. Because human infants are endowed with the capability to attend to the ways inanimate objects are manipulated by other humans. Object boundaries: Adult monkey and human infant above 11 months of age use featural Information processing model to perceive object boundaries. Experiment suggests that monkeys categories food such that they are likely to have â€Å"food kind† (color and shape perception) representations (Yuko Munakata 2001). Successful use of featural information model by monkeys casts doubt on the thesis representation of objects is uniquely human capability. It further seems that even animals do top-down conceptual based processing. Diagrams: logic of pattern recognition The are irregular presentation that artists have been using to create meaningful spatial representation. Now lets see what is the case with the regular patterns so called diagrams. This section looks at issue why do we sue diagrams. Proving theorem is geometry is efficient and easy using diagrams as they provide spatial representation to abstract problems. David Hilbert makes a claim that digram based Euclidean geometry makes hidden assumptions hence it is an effective device for geometrical problems. However the question the whether diagrams are merely heuristic or can provide rigorous means of proving theorem is still a debatable topic. Though claim from (Allewein and Barwise 1996) has revived the argument in favour of diagram as rigorous means of problem solving (Pylyshyn 2003). The Venn diagram representation of sets, illustrates that certain properties of the visual system (the ease with which we locate an element in particular region) can be exploited to facilitate reasoning. Such externalisation exploit the perceptual system to help us recognise patterns (Pylyshyn 2003). Gardener (1982) provides a fascinating discussion of diagrammatic inventions of Leonhard Euler, Sir William Hamilton, Allan Marquand, Johann Lambert, Charles Peirce Lewis Carrol (Charles Dodgson), and Gerrit Marie Mes. There is something obvious about the vision that provides functions that are not as readily available in other forms of reasoning. Vision provides primitive operation for a number of functions (shape recognition, detection of relational properties) The usefullness if diagrams, graphs, charts, and other visual devices relies on the fact that people are good at visually detecting certain geometrical relations. Diagrams enable visual system to keep track of where the information is located in the real world rather than encoding it all in memory argued strongly by O’ Regan (1992). While examing diagrams we don’t look for general properties but also at what properties hold the resulting construction (Pylyshyn 2003) (445) Involvement of visual system is more than goes beyond merely recognising that a certain pattern is present in a particular drawing (Pylyshyn 2003) (446). Spatial metaphors facilitate communication of complex idea and working through bastract problems as diagrams use external memory to represent spatial patterns . (Talmy 2000) (Pylyshyn 2003) (445) In a nutshell, drawing a diagram enables in principle to see the relationships that are entailed by what you recalled, however sparse the set of explicitly noticed relationships might be. In prevision sections I have explained that top down processing in pattern recognition involved in representing meaning in visual arts and also responsible for the break down of patterns in illusion. Even in the abstract process like aesthetic experience key phenomenon is top down processing in pattern recognition. Finally in logical or regular use of visuals is also governed by top-down processing and the key phenomenon is pattern recognition. Right stated by Descartes in 17th Century â€Å" †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬  Instructional Implication: Visuals Literacy â€Å"Visually literacy is training for visual thinking†. This concept has many interpretations and is influenced by various areas like visual language, perceptual and cultural coding, creativity, visual and verbal relationships, deconstructionism, social, theoretical foundations and research. This concept has significantly from 1960 onwards (Dwyer 1994). Visualisation as Rehearsal Rehearsal may be considered to be any activity which causes the learner to hold the information longer in the short term memory. Weinstin and Mayer 1986: Rehearsal strategies are desigined to repeat information while it is in short term memory (Dwyer 1994). Murray and Mosberg 1982 indicated that longer and individual can be involved in rehearsal activities (taking notes, inspecting and interacting with visuals etc) in which he/she is actively processing information, the greater is the possibility that this information will be moved to the long term memory and thus resulting in schema development (Dwyer 1994). Information processing approach focuses on how the human memory system acquires, transforms, compacts, elaborates, encodes, retrieves, and uses information (Dwyer 1994). Gregory in model to explain top- down processing role of side ways role and qualia while misses out on memory structures while Klatzky 1980 focuses on the process of patter recognition in context to memory structures but it misses out top-down and qualia. Hence I present an adapted model that best explains the process of pattern recognition. Adapted from Klatzky Model 1980 and Gregory model of Top-down and bottom up processing. Challenges in the use of visuals as instructional The objective of the instructional strategy should be to develop guidelines for effective use of different kinds of visualisations. To meet educational objectives, guidelines would possess high degree of predictability for the design and visualisation, to ensure that majority of learners receive the intended message in effective manner. This goal is not easy to achieve as due to different kind of illustrations (line drawings, detailed, shaded line drawings, drawings of models, realistic photographs) are not equally effective in achieving different educational objectives for students with different background studying in different cultural/learning settings (Dwyer 1994). Hence there need for effective visual testing. Visual testing Instructional environment purposely designed to facilitate student acquisition, storage and retrieval of designated information. Even though visualization is commonly used to facilitate student information acquisition, most of evaluation strategies currently used are of verbal pencil and paper type (Dwyer 1994). Dwyer and DeMel: â€Å" probably the oldest learning is that any change in the retrieval (evaluation) environment from that which occurred in the original learning environment produces marked decrements in learner performance. Thus most important steps in the research focusing on cognitive information acquisition is the development of instruction unit which contains several different levels of learning (facts, concepts, rule/procedures, problem solving strategies) and appropriate type of tests must be designed to measure the problem solving at each level. Instructional Consistency/ Congruency Canelos presents a useful conceptual rationale for the development o f instructional module for research purpose. The paradigm assumes a hierarchy of learning objectives. Students will not achieve the rules/principle level if they do not posses pre-requisite conceptual base. However if the students possess the conceptual base and the instructional environment does not bring does not bring together relevant concepts in a manner which facilitates rule / principle level integration, learning will not occur. The process of working with objectives, interaction and testing provides instructional congruency while instructional consistency aims to verify that the prerequisite kinds of learning are present; it also requires that the objectives for each category be stated specifically. This Unit development is critical as it alerts the researcher to the fact that the learner are going to be processing information at a different intellectual levels and that different type of instructional experiences need to developed to facilitate the different levels of learning. Visual literacy is becoming less complex as the basic notion of learning with the visuals is becomes more universally accepted. However the field is becoming complicated because of new theories, and new technologies but has a significant implication instruction (Dwyer 1994). Phases in learning Hierarchy and Instructional Consistency/ Congruency Matrix Conclusion I have explained three points first intentionality in pattern recognition makes us unlike the dust particles in Brownian motion. Second- Illusion are good example to understand the leaky architecture of the visual system and brain complex. I have explained that illusion might be caused due to physical causes that bottom up processing dominating or they can be due to cognitive factors that is top-down processing dominates. History of illusion gives insight into the neural basis of visual system. Third- I have explained aesthetic experience, as is the most evolved feature of human beings.

The Crucible Act Two essays

The Crucible Act Two essays To confess to corruption is to sentence your soul to hell, however if you confess to your self, you in turn hold what is rightfully yours, your unflawed name. John Procter was a truthful man that wouldnt just confess to any situation. He had clear characteristics and virtues. Because he was an honest man and didnt want his family name to hold the blemished name of witchcraft. So he did what he thought was right and he refused to confess. He was set in his was of not corrupting his family and friends and he didnt want to go down as lying only to save his own neck, by confessing to witchcraft. I agree with his choice to be killed rather then confess to something that is entirely false just to save his own neck. Especially with his reputation to the town as a honest truthful and loyal man. ...

Understanding the Difference Between Race and Ethnicity

Understanding the Difference Between Race and Ethnicity Its common to see the terms race and ethnicity used interchangeably, but, generally speaking, the meanings are distinct. Race is usually seen as biological, referring to the physical characteristics of a person, while ethnicity is viewed as a social science construct that describes a persons cultural identity. Ethnicity can be displayed or hidden, depending on individual preferences, while racial identities are always on display, to a greater or lesser degree. What Is Race? The term race refers to distinct populations within a larger species. Racial characteristics are physical and can range from skin, eye, and hair color to facial structure. Members of different races usually have relatively minor differences in such morphology- a branch of biology dealing with the form and structure of animals and plants- and in genetics. All humans belong to the same species (Homo sapiens) and sub-species (Homo sapiens sapiens), but small genetic variations trigger varying physical appearances. Though humans often are subdivided into races, the actual morphological variations dont indicate major differences in DNA. The DNA of two humans chosen at random generally varies by less than 0.1%. Because racial genetic differences arent strong, some scientists describe all humans as belonging to a single race: the human race. What Is Ethnicity? Ethnicity is the term used for the culture of people in a given geographic region or of people who descended from natives of that region. It includes their language, nationality, heritage, religion, dress, and customs. An Indian-American woman might display her ethnicity by wearing a sari, bindi, and henna hand art, or she could conceal it by wearing Western garb. Being a member of an ethnic group involves following some or all of those cultural practices. Members of an ethnicity tend to identify with each other based on these shared traits. Examples of ethnicity include being labeled as Irish, Jewish, or Cambodian, regardless of race. Ethnicity is considered an anthropological term because it is based on learned behaviors, not biological factors. Many people have mixed cultural backgrounds and can share in more than one ethnicity. Race vs. Ethnicity Race and ethnicity can overlap. For example, a Japanese-American would probably consider herself a member of the Japanese or Asian race, but, if she doesnt engage in any practices or customs of her ancestors, she might not identify with the ethnicity, instead considering herself an American. Another way to look at the difference is to consider people who share the same ethnicity. Two people might identify their ethnicity as American, yet one is black and the other white. A person born of Asian descent growing up in Britain might identify racially as Asian and ethnically as British. When Italian, Irish, and Eastern European immigrants began arriving in the United States, they werent considered part of the white race. This widely accepted view led to restrictions of immigration policies and on the entrance of â€Å"non-white† immigrants. Around the start of the 20th century, people from various regions were considered to be members of sub-categories of the white race, such as â€Å"Alpine† and â€Å"Mediterranean† races. These categories passed out of existence, and people from these groups began to be accepted into the wider â€Å"white† race, though some retained distinction as ethnic groups. The idea of an ethnic group can also be broadened or narrowed. While Italian-Americans are thought of as an ethnic group in the United States, some Italians identify more with their regional origins than their national ones. Rather than view themselves as Italians, they consider themselves Sicilian. Nigerians who recently moved to the U.S. might identify more with their specific group from within Nigeria- Igbo, Yoruba, or Fulani, for example- than their nationality. They might have completely different customs from African-Americans who descended from former slaves and whose families have been in the U.S. for generations. Some researchers believe that the concepts of both race and ethnicity have been socially constructed because their definitions change over time, based on public opinion. The belief that race is due to genetic differences and biological morphologies gave way to racism, the idea of superiority and inferiority based on race, they charge. Persecution based on ethnicity, however, also has been common. Race Trumps Ethnicity New York University sociology professor Dalton Conley spoke to PBS about the difference between race and ethnicity for the program â€Å"Race: The Power of an Illusion†: â€Å"The fundamental difference is that race is socially imposed and hierarchical. There is an inequality built into the system. Furthermore, you have no control over your race; it’s how you’re perceived by others.† Conley, like other sociologists, argues that ethnicity is more fluid and crosses racial lines: â€Å"I have a friend who was born in Korea to Korean parents, but as an infant, she was adopted by an Italian family in Italy. Ethnically, she feels Italian: She eats Italian food, she speaks Italian, she knows Italian history and culture. She knows nothing about Korean history and culture. But when she comes to the United States, she’s treated racially as Asian.† Key Takeaways Differences between race and ethnicity: Race is biological, while ethnicity is cultural.Ethnicity can be displayed or hidden, while race generally cannot be.Ethnicity can be adopted, ignored, or broadened, while racial characteristics cannot.Ethnicity has subcategories, while races no longer do.Both have been used to subjugate or persecute people.Some sociologists believe that racial divisions are based more on sociological concepts than biological principles.

Luxury Consumption in China Literature review Example | Topics and Well Written Essays - 4500 words

Luxury Consumption in China - Literature review Example Despite of these challenges, the luxury industry still is becoming highly attractive as the affordability of consumers is also increasing. As the middle class in the world is gaining strength and becoming more loyal to luxury branded goods, luxury industry still have a number of lucrative market segments to be catered. It was estimated in 2003, that the financial returns of luxury goods manufacturing industry globally was $ 90 billion, which crossed the $ 150 billion mark in 2007. By offering services and products to the untapped market segments, the luxury industry is expected to increase the size of its returns by $ 400 billion by the end of year 2015 (Heaney et al., 2005). As the size of luxury branded goods industry is increasing, the format of business is also changing. Now, luxury goods manufacturing businesses are no more privately or family owned business, but transforming into public limited companies. In this manner, the luxury branded goods industry is attracting investments from all around the world which enables them to invest heavily on research and development to understand consumer behavior. Understanding consumer behavior is essential for expanding the size of luxury businesses into untapped international markets. The understanding of consumer behavior has delivered its fruits in recent years, which is evident from the dramatic expansion of industry’s size in India, China, South Africa and Brazil. Especially China has remained the front runner, where consumers are becoming more brand conscious and spending lavishly on purchase of luxury branded goods (Michman & Mazze, 2006). ... Especially China has remained the front runner, where consumers are becoming more brand conscious and spending lavishly on purchase of luxury branded goods (Michman & Mazze, 2006). Being the fastest growing economy in the world, China offers the biggest market place to luxury brands. The increase in the economic development has resulted in the increase in personal incomes of Chinese consumers. Due to this, a large section of the consumers has formed a market segment which is wealthy and social stimulators, which is described as the â€Å"new rich†. This segment of the market has the tendency to live a celebrity lifestyle and satisfy their desire for expensive and sophisticated goods and services (Dubois et al., 2005). According to a research of Ernst and Young, it was estimated that by the end of 2015, China would account for 29% consumption of luxury goods and services in the world. This rate of consumption would cause China to become the 2nd largest consumer of luxury goods and services in the world. This is the reason, that heavy investments are made by luxury brands to understand the consumer behavior of Chinese consumers, so that the product and marketing strategies can be developed accordingly (Ernst & Young, 2005). Keeping in view the lucrative opportunities available to luxury brands in China, a number of these brands has installed production facilities in the country. These include Bally, Gucci, Ferragamo and Luis Vuitton. Other brands like Zara, Jimmy Choo and others are preparing their action plans to enter Chinese market as a local producer of luxury goods, to take full advantage of lucrative opportunities in the country. Beside factories in China, a number of luxury brands have their subsidiaries, operational facilities and stores in
