How hip hop has a positive influence in America Essay

How hip hop has a positive influence in America - Essay Example In this paper I will expound on the positive influences of hip hop music in America. The American society has remained silent on issues affecting them for a long time but hip-hop has been like a savior to those people. This music generally educated and shed light on issues that related or affected life for example violence through promoting a message of peace among the Americans. Hip- hop was used as a means of passing grievances and also by people who wanted to raise their views to the public. Some hip- hop songs tried to show the seriousness and effects of using drugs and it also spread communal messages across the country to inform people on what was happening in the ghetto life. In addition, hip-hop music has been a means of expression of the minority. Its main aim is to raise voices for the youths alienated  and show that they also have positive impacts in helping the community. Moreover, those people who are mistreated silently and they have no-one whom they can share their problems with are considered by the hip- hop music. In addition, graffiti which is also associated with this genre of music renders a means of unconventional means expression. Hip hop also encourages its listeners who are mostly youth to never give up in life and to push on and they will succeed in spite of the problems they are facing. Thus, hip-hop culture has had a positive influence of being the voice of those who are rendered helpless and voiceless by their status either due to hardships, race etc. Hip- hop has endorsed acute thinking on issues that the media find sensitive or fear to raise to the public. It has been used as tool for activism against vices in the society. In the United States of America Hip- hop has really tried in the elimination of racism. Hip- hop dancing moves have been used to eliminate violence. Due to gender inequality in America, hip-hop has been promoting issues affecting gender equality by making sure that

The Impact Prison Has on Families and Children Essay

The Impact Prison Has on Families and Children - Essay Example However, studies have revealed that problems ensue when parents have committed violations and infractions that led to their imprisonment (Robertson, 2007; King, 2002; Cunningham, 2001). As emphasized, parental imprisonment have been validated to provide negative effects on the lives of the children and those of the family members. The current essay hereby aims to determine and expound on the impact prison has on families and children by initially enumerating the effects of parental imprisonment on children in terms of their behavioral manifestations, in terms of financial situations and in the parent-child relationships or bonds. Effect on Children’s Behavior When parents are incarcerated, the reactions of children could be varied depending on demographic factors: their age, the social status of the family, the income level, peers, and the availability and access to forms of support. As disclosed by Robertson (2007), â€Å"often children of prisoners are discriminated against and stigmatised as a result of parental imprisonment and have suffered from trauma, fear, shame, guilt and low self-esteem. Relationships with other family members frequently suffer.Some children become withdrawn, are affected by increased health problems and regressive behaviour such as bed-wetting, suffer worsening performance and attendance rates at school or display increased aggression, antisocial or criminal tendencies† (Robertson, 2007, p. 9). These findings were corroborated in the study conducted by King (2002) who revealed that among the changes eminent from children’s behavior when their parent/s were imprisoned include: either becoming withdrawn and quiet or being hyperactive; acting up with the remainign caregiver; depression; and shyness exhibited to imprisoned parent/s (p. 56). Likewise, physical and mental health changes were also reported by Roberston (2007) to wit: â€Å"noted problems have included: changes in sleep patterns or eating behaviour; sta rting or increasing their use of drugs, alcohol and tobacco; stress; depression; and symptoms of post-traumatic stress disorder such as flashbacks about the crimes or arrests† (p. 9). Effect on Financial Situations Evidently, for very young children, the primary effect of parental imprisonment is the curtailment of regular and appropriate financial support. If the parent who was incarcerated was the breadwinner, the sole parent left to attend to the financial needs of the family will bear the burden for financial support. On the other hand, for parent/s who have had previous experiences of drug abuse prior to the incarceration were noted to have led to some improvement in the financial situation of the family (King, 2002, p. 54). Also, as emphasized by Cunningham (2001), â€Å"incarceration may necessitate relocation for the rest of the family, and hence disruption of schooling and loss of support networks. Moving house may result from economic hardship arising from the loss of the breadwinner, or a desire to escape media or family attention† (p. 36). Effect on Parent-Child Relationships Due to the restrictions posed in the prison setting, prisoners with children were reported to have difficulties maintaining their relationships with their children. As a consequence, there are perceived diminishing of parent-child established bonds and the loss of parental authority (King, 2002). Likewise, as it was apparently noted that children with parents

Information resource managment - Essay Example The paper will consider the role of a chief information officer in the organization USAID. The United States Agency for International Development is a United States of America based organization that offers assistance to international countries especially those that might be disaster stricken; hit by natural calamities like typhoons, earthquakes and drought. The USAID organization is highly organized to ensure that all the funds that are come in, are well accounted for, and the solutions offered to different companies are well tailored so as to suit their different needs. The USAID organization operates under the mandate of the United States Secretary of State Office and US Federal government office. Being under the US government administration, the office is able to take advantage of the latest information technology related information through the government administration. The United States government is one of the most competitive in terms of availability of the latest information and access to information technology systems to support technical services available. Being part of the government, USAID is able to access and make use of the latest information technology information that it can utilize to make its systems efficient. The USAID information systems ensure that the necessary aid is delivered where it is required. As the Chief Information Officer at USAID, the professional in charge of the title ensures that the policy that is formulated by the organization is in line with the whole organizational strategy, mission and vision (USAID, 1). The CIO also ensures that the USAID information technology related policy is aligned to those of the communities that the agency intends on assisting.

Hotel on a corner of bitter and sweet Essay Example for Free

Hotel on a corner of bitter and sweet Essay Maintaining privacy and confidentiality for patients is a fundamental duty of care as a nurse. It is clearly stated that a nurse must treat personal information obtained in a professional capacity as confidential (ANMC, 2003, pg. 4). Although the terms privacy and confidentiality are often interchanged, they should be distinguished. Privacy refers to ones ownership of ones body or information about ones self, whereas confidentiality refers specifically to limits upon private information revealed in confidence, as a responsible promise that the information will not be revealed to others (Kerridge et al. , 1998). It is essential that the data will be used and reported in such a way that no one is able to identify the source (Behi Nolan, 1995). It is important to uphold both the privacy and confidentiality of patients whilst in nursing care to protect clients against the morally harmful consequences that can occur when unconsented disclosures are made (Crisp Taylor, 2005). For example, a clients newly diagnosed HB positive status could result in the client being rejected by family and friends and hence left without social support at a time when most needed. The Privacy Act 1988 requires Commonwealth agencies to conform to a set of Information Privacy Principles when dealing with personal information. State and territory legislation also places similar obligations on their respective agencies, which includes hospitals (Crisp Taylor, 2005). At common law, there are expectations that contracts will contain a confidentiality clause and tort will include a duty of confidentiality (Crisp Taylor, 2005). Under most circumstances information gained in the professional-client relationship should not be disclosed, however there is an exception if there is an overriding legal reason that disclosure should be made. For instance, this occurs where such disclosures help prevent harm to innocent others (Crisp Taylor, 2005), such as in a case that a client disclosed that he intended to kill someone he disliked. In conclusion, protecting privacy and confidentiality for patients is essential in the field of nursing, both morally and legally, as this ensures that the patients well-being are not jeopardized by the unwarranted disclosure of such confidential material.

Methods To Prevent Barre In Knitted Fabric

Methods To Prevent Barre In Knitted Fabric In textile production, one of the most common and perplexing quality issues is barrà ©. The factors that can cause or contribute to barrà © are varied and diverse. For this reason, when a barrà © problem is detected, the skills of a sleuth may be required to expose the problem and eliminate its cause. Once a cause is identified, steps can be taken to minimize or eliminate the barrà ©, and better quality fabrics can be produced. This discussion will center on knitted fabrics. DISCUSSIONS The noun barrà © is defined by ASTM1 as an unintentional, repetitive visual pattern of continuous bars and stripes usually parallel to the filling of woven fabric or to the courses of circular knitted fabric. In a warp knit, barrà © normally runs in the length direction, following the direction of yarn flow. Barrà © can be caused by physical, optical, dye related differences in the yarn, geometric differences in the fabric structure, or by any combination of these differences. A barrà © streak can be one or several courses wide. A typical characteristic of barrà © is that it generally consists of stripes that repeat. Isolated or intermittent defects may or may not be barrà ©. 1 ASTM D123-96a Standard Terminology Relating to Textiles 1 Various aspects of barrà © are important for consideration and discussion. The first is the identification of barrà ©. Secondly, how can barrà © be analyzed? What are the causes of barrà ©, and finally, how can it be prevented? IDENTIFICATION OF BARRÉ The first step in a barrà © investigation is to observe and define the problem. Barrà © can be the result of physical causes that can usually be detected, or it can be caused by optical or dyeability differences that may be nearly impossible to isolate in the fabric. Barrà © analysis methods that help to discriminate between physical barrà © and barrà © caused by other reasons include Flat Table Examinations, Light Source Observation, and the Atlas Streak Analyzer. Flat Table Examination For a visual barrà © analysis, the first step is to lay a full-width fabric sample out on a table and view both sides from various angles. Generally, if the streaky lines run in the yarn direction that is in the course direction, apparent color differences can be seen by looking down at the fabric in a direct visual line with the yarn or course direction, and the defect can be positively identified as a barrà © defect. Viewing the fabric with a light source in the background will show if the barrà © is physical. Light Source Observation After completing an initial Flat Table Examination, a Light Source Examination may provide further useful information. Full width fabric samples should be examined 2 under two surface lighting conditions, ultraviolet (UV) and fluorescent light. Observations that should be made while viewing under lights are: 1. the frequency and width of the barrà ©, 2. whether the streaks are dark or light, and 3. the total length of pattern repeat. Ultraviolet light, commonly referred to as black light, allows the presence of mineral oils to be more easily detected, due to their radiant energy (glow). When observed under UV light, fabrics with streaks that exhibit glow suggest improper or insufficient preparation. A change in composition or content of oil/wax by the spinner or knitter without appropriate adjustments in scouring can create this problem. Fluorescent lighting simulates the mode of observation that is common to most inspection tables in mills and will highlight whether the barrà © is perceivable in an industry quality control setting. Atlas Streak Analyzer The function of the Atlas Streak Analyzer is to isolate barrà © caused by physical differences. A fabric swatch is combined with polystyrene sheet film, and the Atlas Streak Analyzer produces a plastic impression of a fabric surface by incorporating specific conditions of pressure and heat. The absence of color on the plastic impression ensures that only physical streak effects will be seen. The plastic impression is examined to determine whether the streak alignment matches the 3 streaks observed on the fabric. However, impressions made from spun yarns such as cotton can be difficult to read due to the inherent yarn variation characteristic of spun yarns. Also, a too rapid cooling of the test specimen after making an impression can produce a moirà © pattern. From a valid plastic impression, the barrà © source can be identified as: 1. physical with all streaks showing on the impression, 2. optical or dyeability variations where none of the color streaks are aligned on the impression, and 3. a combination of physical and dyeability differences where some streaks align with those on the impression, and some do not. Fabrics with combination causes present the greatest challenge for analysis. If the streak analyzer indicates the same barrà © pattern as seen in the fabric, then the barrà © stripes are physical in nature. This can relate to several physical causes such as yarn tensions, stitch length, yarn count, twist differences, etc. Yarn tension causes can be found by raveling adjacent courses and measuring the lengths of yarn removed from each course. If all the lengths raveled from the fabric are the same, the pieces can be weighed to determine if the yarn counts are the same. 4 If the plastic replica shows no stripes, then the barrà © is due to chemical causes or to light reflectance differences. Chemical causes relate to improper preparation, and light reflectance differences relate to non-uniform dyestuff penetration or reflectance. The next step is to remove the color and evaluate the stripped sample before re-dyeing to determine if the removal of dye was complete and if the barrà © is still present. An uneven or incomplete stripping can indicate an additional strip. If the color is stripped uniformly and the barrà © is gone, then the sample should be re-dyed. If after stripping and over dyeing the fabric no longer has barrà ©, then the barrà © was caused by improper preparation. If the barrà © remains, then the problem is related to optical or light reflectance problems. PHYSICAL BARRÉ ANALYSIS When the cause of barrà © is determined or presumed to be physical in nature, physical fabric analysis should be done. Physical barrà © causes are generally considered to be those which can be linked to yarn or machine differences. Methods of physical barrà © analysis include fabric dissection, microscopy, and the Roselon Knit Extension Tester. Fabric Dissection To perform accurate fabric dissection analysis, a fabric sample that contains several barrà © repetitions is required. First, the barrà © streak boundaries are marked by the placement of straight pins and/or felt markers. Individual yarns are removed from light and dark streak sections, and twist level, twist direction, and cut length 5 weight determinations are made and recorded. For reliable mean values to be established, data should be collected from at least two light/dark repeats. After compilation of yarn information, the numbers can be compared individually to adjacent yarns as well as by groupings of light and dark shades. Microscopy Microscopic examination is useful for verifying yarn-spinning systems. Yarns from different spinning systems can have different light reflectance and dye absorption properties resulting in barrà © when mixed. Ring-spinning produces yarn that is smooth with all fibers twisted in a tight helix. Open-end spinning produces yarn with wrapper fibers that form a belt around the diameter of the yarn at irregular intervals. Air jet spinning produces yarn with more wrapper fibers that form a continuous spiraling band around the inner fibers that are more parallel to the axis of the yarn. Microscopy can also reveal a shift in loop formation in knitted fabrics when twist direction (S and Z) differences are present. Roselon Knit Extension Tester2 Barrà © produced by knitting machinery is relatively common, is the easiest to see in the greige, and is the easiest to correct. Often uneven yarn tension during knitting may be a cause. To test for uneven tension, the Roselon Knit Extension Tester can be used. For this test, a fabric sample is cut and raveled to yield yarn samples from light and dark streak areas. The yarn ends are taped and clamped 2 Source: Spinlon Industries Incorporated, 18 S. Fifth Street, Quakertown, Pennsylvania 18951 6 to the tester. As each yarn is stretched to the maximum extension point, the points are plotted on graph paper. Comparisons are usually made visually rather than mathematically. CAUSES OF BARRÉ The varied and diverse causes of barrà © can generally be summed up in one word INCONSISTENCY. An inconsistency that leads to barrà © can originate in one or more of the following categories: ! fiber quality/raw material management, ! yarn formation/supply management, ! knitting processes, and ! preparation and dyeing techniques Fiber Quality/Raw Material Management 1. Failure to control fiber diameter (micronaire or denier) from laydown to laydown. 2. Too high a C.V. of micronaire in the laydown for a given mills opening line blending efficiency. 3. Failure to control the fiber color in the mix (grayness Rd, yellowness +b). 4. Failure to control maturity/fineness in a laydown 5. Most, if not all, fiber barrà © can be controlled by the above four items; however, under certain unusual circumstances, it may be beneficial to also select mixes using ultraviolet reflectance information for each bale of cotton. 7 Micronaire Average micronaire must be controlled within a laydown and from laydown to laydown. Controlling average micronaire in the laydown may not be sufficient to completely eliminate barrà ©. Other micronaire related causes of barrà © are: ! > 0.2 difference in micronaire. ! > 0.1 change in mix-to-mix average micronaire. ! > 12.0 % CV of micronaire within the laydown. It may be necessary to change the laydown averages periodically to make use of all the bales in the warehouse. This must be done slowly with no more than a 0.1 change in mix-to-mix averages. Figure 1 shows acceptable changes in micronaire from laydown to laydown. No barrà © from micronaire differences should show in knitted fabrics when yarns are mixed on the knitting machine from consecutive laydowns. However, if laydowns vary more than 0.1 micronaire, for example laydowns #1 (4.3 mic.) and #6 (4.6 mic.) in Figure 1, then barrà © is much more likely to occur. 8 Figure 1: Slowing Changing Micronaire Average in Laydown Acceptable Change in Micronaire From Laydown to Laydown3.53.63.73.83.94.04.14.24.34.44.51234567891011121314Laydown NumberMicronarie Figure 2 shows a high CV% in the micronaire for bales within a laydown. The laydown shown has 24 bales with an average of 4.1 micronaire and a CV% of 17.7. The change in micronaire from bale to bale is more than a 0.1 change. Also, the CV% is more than 12.0% and would probably result in barrà ©. High Micronaire CV% in Laydown3.53.73.94.14.34.54.7123456789101112131415161718192021222324Bale NumberMicronaireAvg. 4.1 CV% 17.7 * Figure 2: Results of Changing the Micronaire Average too Rapidly Max +/- 1.0 mic 9 Maturity and Fineness Although micronaire gives an indication of fiber maturity, it does not directly measure that property. Maturity and fineness related causes of barrà © include: ! Blending cotton from different growth areas or seed varieties. ! Immature fiber content such as white specks, neps, etc. Yarn Formation/Supply Even with proper fiber selection to reduce raw material effects on barrà ©, techniques in the opening, cleaning, blending, and carding areas can have an impact on barrà ©. These variations can occur at carding where different amounts of non-lint content removal from card to card can be a problem. Poor blending of fiber from opening through finisher drawing cannot be overlooked. In ring spinning, the running of different types of spindle tapes and the use of different cots or new and used cots mixed together on the same frame can create barrà ©. Faulty management in the spinning plant can result in the following yarn related causes of barrà ©: 1. Yarn count variations. 2. Yarn twist variation. 3. Wrong yarn size, color, blend level, twist direction. 4. Mixed yarn lots. 5. Mixed shipment dates of same dye lot. 10 6. Uneven waxing or oiling of yarn 7. Improper conditioning. Knitting Processes and Yarn Management The set-up and operation of a knitting machine is complex and requires precision settings to produce first quality goods. Machine related causes of barrà © include: 1. Different stitch settings (stitch lengths). 2. Improper tension at a feed. 3. Faulty cylinder or dial cam settings. 4. Malfunctioning of storage or tape feeders. 5. Improper threading of yarn. 6. Variations at take-down or spreader system. 7. Machine vibration. 8. Dirt, lint, and/or yarn fragments in the camming system, tricks, needles, or sinkers. 9. Variation in oil content. 10. Worn needles, which generally produce length direction streaks. 11. Uneven cylinder height needles (wavy barrà ©). 12. Worn cylinder and/or dial. Even with a properly set-up machine, barrà © can still occur at knitting due to poor yarn management. Examples of poor yarn management at knitting include: 11 1. Mixing yarns of different counts. 2. Mixing yarns from different spinning systems. 3. Mixing yarns with different blend levels. 4. Mixing yarns from different suppliers. 5. Mixing yarns with different twist level/twist direction. 6. Mixing yarns with different degrees of hairiness. 7. Mixing yarns with different amounts of wax. 8. Mercerization differences. 9. Excessive backwinding or abrasion during this process. 10. If yarns are conditioned, then each lot must be uniformly conditioned. Preparation and Dyeing Techniques Normally, dyehouses have standard preparation procedures and formulas that work very well in terms of removal of non-fibrous contaminants and natural fiber pigmentation. However, some fabrics can exhibit barrà © that is caused by either optical or dyeability issues. Often, the barrà © is not created in dyeing, but can be highlighted. In this scenario, the dyeing is not the cause but the messenger of the problem. Typically, barrà © is not a problem in whites, only in dyed fabrics. Therefore, if a fabric is known to have barrà ©, then that roll should be processed into a white. 12 Preparation can help mask barrà ©, but cannot and will not eliminate it. The cause of the barrà © must be eliminated for future rolls to be free of the defect. The scour and/or bleach procedure can be intensified to mask the barrà ©. This can be done by combinations of using a higher temperature or longer processing times. Usually the chemistry will remain the same; however, in some cases, it may have to be increased or changed. If any changes are made in the preparation procedure, the fabric and resultant shade will possibly change in whiteness, strength, and appearance. In fact, the whiteness will almost always change. If whiter, the old dye formula will need to be adjusted. The strength of the fabric may be affected to the point where it becomes a problem. Finally, the surface of the fabric may change so that it may not match previous lots. As a result of more aggressive preparation to cover barrà ©, it is important to evaluate such changes on small samples in the lab or a sample machine. Tension can play an integral role in not only the formation of the fabric, but also during preparation, dyeing, and finishing. As with all variables, it must be controlled to known parameters and be consistent. Any inconsistencies in tension could change the morphology of the cotton (i.e. during mercerization), level of dye pick- 13 up, or surface appearance (i.e. during mechanical finishing such as brushing or sanding). PREVENTION OF BARRÉ As discussed in the text, barrà © is caused by inconsistencies in materials, equipment, or processing. To prevent barrà © from occurring, consistency must be maintained through all phases of textile production. Stock yarns should be properly and carefully labeled to avoid mix-ups. Fugitive tints and/or marked cones can be useful for accurate yarn segregation. Inventory should be controlled on a first in/first out basis. All equipment should be properly maintained and periodically checked. In spinning and knitting before beginning full-scale production, sample dyeings can be done to check for barrà ©. Knit machine operators should be trained to look for barrà © as it occurs in the greige. If spotted, the machine should be stopped until the cause is eliminated. Salvaging a fabric lot with a barrà © problem may be possible through careful dye selection. Color differences can be masked by using shades with very low light reflectance (navy blue, black) or high light reflectance (light yellow, orange, or finished white). Dye suppliers should be able to offer assistance in this area. Also, if the cause of the barrà © is an uneven distribution of oil or wax, a more thorough preparation of the fabric before dyeing may result in more uniform dye coverage. 14 With close cooperation between production and quality control personnel, barrà © problems can be successfully analyzed and solved. Recommendations to minimize barrà © include: ! Knit an entire dye lot from the same knitting machine. ! Use only yarn from the same spinning lot. ! Use only from the same shipment date if possible. ! If yarn shipment dates must be mixed, then use consecutive shipment dates. ! Determine through laboratory analysis and experience if the preparation procedures are sufficient or can they be modified to eliminate the problem. ! Determine if some shades and dyestuffs are less susceptible to showing barrà ©, and apply those to problem fabrics. ! Make use of yarn/fabric analysis systems such as CYROS ®. ! Identify those rolls within a dye lot that have mixed yarn shipment dates so that it is known when the fabrics go through the dyehouse. ! Identify dye lots that have rolls from different yarn shipments before dyeing. CASE STUDY IN BARRÉ A 100% cotton, ring-spun single jersey style T-shirt is knitting in production with a yarn that does not have a barrà © problem. This style has been knitting for numerous days and no more of the yarn is available for creeling on the machine as the yarns are knitting out. Some yarn packages are skinners and others are full five-pound packages. The machine is 24-inch diameter with 80 feeds. 15 When the new yarn is creeled onto one of the 80 positions, the mixing of yarn shipment dates begins to take place. For this discussion, we will assume that this new yarn will cause barrà © when mixed with the old yarn. Once all positions are knitting the new yarn, there will be no barrà ©. How many rolls of fabric will have barrà © when both these yarns are present in the rolls? If the knitter is making 50 pound rolls, then each yarn package will supply 1/80th of the 50-pound roll or 0.625 pounds of yarn. Therefore, the new yarn will make 8.0 rolls of fabric with barrà © (5-pound package divided by 0.625 pounds per package for a 50 pound roll). It is important to realize that while this new package is knitting, other old yarn positions on the creel are also being replaced by new yarns. By the time the first new package has knitted out, all feeds will be using the new yarn. When the last old package is replaced and all positions have new yarn, the barrà © will disappear. Often, many machines will be knitting the same style. If ten machines are knitting this style and are using the old yarn and new yarns are placed on these 80 feed machines, then the total number of rolls knitted with barrà © will be 80. A total of 4,000 pounds of fabric will be made with barrà ©. If the style in question weighs 5.8 ounces per linear yarn, then a total of 11,035 yards of fabric will be made. Further, if it can be assumed that each yard of fabric can make 1.2 shirts, then a total of 13,240 defective T-shirts will be made. This is 1,103 dozen 16 garments. If the cost per shirt is $2.05 per unit, then a loss of $27,142 plus is realized. If open-end yarn was used for this case study instead of ring-spun yarns, then 8-pound packages of yarn could be used. This would result in 128 rolls containing 6,400 pounds and 17,655 yards of fabric. From this, 21,186 T-shirts (1766 dozens) would have been made. Based on a cost per shirt of $1.86, the loss would be $39,405. The result is that bigger packages mean bigger losses. The best methods to reduce the possibility of this catastrophe are listed below: 1. When mixing yarn shipment dates of only one week, try to reduce the number of machines using the old and new yarns. 2. As more machines are expending the old yarn, consolidate the old packages to fewer machines. This means removing the yarns from one creel and using them on other machines that are still knitting the old yarn. 3. Knit dye lots from a single machine if possible. 4. When a roll is known to have mixed yarns, a laboratory dyeing should be done on a swatch from the roll to determine if barrà © is present. If not, then proceed as normal. If barrà © is present, then the roll should be processed in 17 shades that are not known to be barrà © sensitive or prepared with more aggressive chemistry. CONCLUSIONS It is evident that barrà © is a problem that results from inconsistencies and is a result of poor management of fiber, yarn, and/or related knitting processes. The spinner, the knitter, and the dyer must communicate and work as a team to reduce the potential for barrà © to occur. A well planned and executed system of monitoring the spinning, knitting, dyeing, and finishing systems in the mill can provide for defect free fabrics. 18

Gattaca Defying All The Premises Philosophy Essay

Gattaca Defying All The Premises Philosophy Essay Imagine a society where everyone is more intelligent and healthier than you. Imagine a society where your genetic makeup-engineered or natural-determines the job for which you are eligible, whether or not you can be insured, and who associates with you. Gattaca by Andrew Niccol tells the story of Vincent, a young man naturally and traditionally engendered in a world where genetic engineering is the followed pattern to have a child. Few minutes after his birth, Vincents fate is revealed through a DNA analysis. His first genetic test revealed high probabilities of hyperactivity, sight troubles and serious heart diseases, a life expectancy of 30 years and 2 months and quite low intellectual faculties. At that time, the artificial insemination of test tube babies selected according to their genetic potential had become for many people the natural way of making children. But Vincents parents had preferred to let the other nature take its course. Of course they regretted it, and for their next child they went to see a geneticist. A perfect son has been born to them, a son who deserved to be called Anton, like his father. While Vincent was forced by his genetic code and the system to study at home, Anton was taller and better at anything than his elder brother. They used to play at softy. The game consisted of swimming in the sea as far as possible and being the last to make an about-turn. Vincent was always the softy. But besides his weak health, he had a very strong will. His lifelong dream was to join Gattaca, probably the most prestigious company on earth whose activity was to explore galaxies, and go into space. To achieve his aim, he did not stop studying during his whole adolescence, despite his fathers discouragements. The film shows a world where life is highly determined by genetics, and happiness is mostly based on the quality of the genetic profile, a kind of identity card for people. Vincent, who wants to become an astronaut and work for Gattaca, overcome s all the difficulties presented to him defying all the premises of the genetic engineering. However, it is not so clear that only free will is which will lead him to his dream; that significant amount of determination has to do with his success. At a time when we read about cloned sheep and the unraveling of the human genome, the science in Gattaca is theoretically possible. In the futuristic world of Gattaca, society has developed the technology to manipulate human procreation and designed children with impeccable genetic compositions. I suspect most people will order up the make and model they wanted rather than take chances on a throw of the genetic dice. Everyone will live longer and healthier in the Gattaca world. As a result, a new social caste system is created in which the artificially created, genetically superior humans called valids, dominate all major aspects of society. In contrast, the naturally born humans, called invalids, become a mistreated minority. Although all aspects of society are affected by the new genetic technology, the greatest impact is on the job market. As a result, the easiest way to analyze the job market is to compare the occupations of the valids and to the occupations of the invalids. Vali ds are instantly granted powerful, high-paying jobs, regardless of their training or background. For example, when applying for a job at the Gattaca Aerospace Corporation, Vincent, under an alternate identity, is only required to provide a blood test before he is hired and prepped for flight missions into space. Valids also tend to have computer-based jobs so that they make full use of their genetic intelligence. Invalids are only allowed to have demeaning, low-paying jobs. For instance, before assuming an alternate identity, Vincent is only allowed to work at the Gattaca Aerospace Corporation as a cleaner. In addition, invalids are forced to take jobs in which they perform manual labor. I think the Gattaca world is a realistic future even though it might face a lot of social and ethical problems. Firstly we are getting to the technology that is needed for the level of genetic engineering in Gattaca. Human Genome project begun formally in 1990, the U.S. Human Genome Project was a 13-year effort coordinated by the U.S. Department of Energy and the National Institutes of Health. The project originally was planned to last 15 years, but rapid technological advances accelerated the completion date to 2003. The goals were to identify all the approximately 20,000-25,000 genes in human DNA, determine the sequences of the 3 billion chemical base pairs that make up human DNA and store this information in databases. The knowledge about the effects of DNA variations among individuals can lead to revolutionary new ways to diagnose, treat, and someday prevent the thousands of disorders that affect us. However there are many social and ethical problems that human might face on the way to Genetic engineering in Gattaca. Firstly people were taking other peoples DNA without that persons consent in Gattaca, and this could also happen in reality too. Just like what Vincent said in the movie Of course, its illegal to discriminate. But no one takes the law seriously. People were unable to choose their own destiny. You would never be able to hope or dream of anything because your life is already planned out for you. If its not a part of your life plan, then that would be something you dealt with. Invalids were being discriminated against. According to the Nuremberg Code, which is a set of ethical rules a doctor or scientist must follow when experimenting on a human, it states that The voluntary consent of the human subject is absolutely essential (Nuremberg Code, 1949). In Gattaca, when applying for a job, the interviewer often takes saliva or a sample of urine from the interviewee without telling him/her why. Normally, if a person says no, after the interview, the interviewer would simply take DNA from a handshake, the doorknob, or even the seat without the interviewees permission. This is serious violations of the free will and rights of human beings. Secondly, discriminations could be anywhere. In the movie, people can actually choose the traits and gender of the child. This can cause a lot of problem: e.g. in China most people want boys rather than girls because people think boys could do more labor works than girls and boys can pass down their family name. As a result, the male-female ratio of world population could change drastically. The discrimination against in-valid in the movie could happen in reality too. According to the Universal Declaration of Human Rights, everyone has duties to the community which allow the free and full development of a persons personality. Vincent has the right to express himself, which he is unable to do because he would never be allowed to because of his heart disease. Furthermore, the Universal Declaration of Human Rights states that in the exercise of his rights and freedoms, everyone shall be subject only to such limitations as are determined by law solely for the purpose of securing due to recognition and respect for the rights and freedoms of others and of meeting the just society (Universal Declaration of Human Rights, 1948). Vincent worked really hard and strived to become an astronaut but was held back because he wasnt perfect enough. This article is saying that a person should be allowed to express oneself as long as it is legal and not disturbing the public order or general order or general welfare of others. Vincent becoming an astronaut wouldnt affect any of these, he cannot even get a chance to try in the Gattacan world. All are equal before the law and are entitled without any discrimination to equal protection to the law. All are entitled to equal protection against any discrimination in viol ation of this Declaration and against any incitement to such discrimination (Universal Declaration of Human Rights). The invalids were treated inhumanely, as if they were all criminals. Discriminations problems can be one of the biggest concerns of most people if Gattaca world becomes real. Thirdly if everybody uses genetic engineering, people would have a longer life span. Earth may face an energy crisis and cause the extinction of human beings. Another problem might come from different religions, a lot of people believe in natural process too. Furthermore this is not something that could be undone easily, once people start using genetic engineering, they will just rely on it. Fortunately, most of the problems I came out with were considered by experts from the Human Genome Project. One of the main goals of the Human Genome Project is to address the ethical, legal, and social issues (ELSI) that may arise from the project. (Human Genome Project 2003) The whole project has nine princ iples: 1. Fairness in the use of genetic information; 2. Privacy and confidentiality; 3. Psychological impact and stigmatization; 4. Reproductive issues; 5. Clinical issues; 6. Uncertainties; 7. Conceptual and philosophical implications; 8. Health and environmental issues; 9. Commercialization of products. Those nine principles can ensure everyone that the problems happened in the movie Gattaca will not occur in reality. I think there is a bright future for Human Genome Project as long as the nine principles are followed. I really enjoyed Gattaca. It raises some very good points that question the uses of technology in the not so distant future. The use of genetic research has led to humanity bio-engineering children to be free of defects and disabilities. Furthermore, I feel really pleased for Vincent as he mixes with members of the valid world despite his own in-Valid condition, he manages to gain considerable respect and admiration because of his persistence, even from people unaware of his status as a genetic impostor. Although Vincent is at the lower end of the genetic hierarchy, it is due to his ferocious determination and unquenchable desire that he is able to rise above his colleagues and achieve his dreams. It is these qualities that deem the central protagonist unique in the world of Gattaca. In the end, this movie also made me question where we should draw the line between science and ethics.
