Causes Of Computer Vision Syndrome Health And Social Care Essay

Causes Of Computer Vision Syndrome Health And Social Care Essay The computer has become backbone of todays occupational settings. They are the heartbeats of the modern world. Computers are everywhere from kitchen to concrete mixers, from planes to pockets. Without computer, world has no global awareness. It has created a brand new environment. A new culture has been born- free, rapid and universal, where people share their knowledge and expertise. Computer has spread its wings within the nursing profession also and nurses are no longer passive users of computer technology, but are now becoming the innovators, developers and implementers of computer systems. (Suparna.K,et.al., (2005). Vision is our most precious sense. Our eyes are in constant use every waking minute of every day. Over 80% of our learning is mediated through our eyes, indicating the important role our vision plays in our daily activities. Vision disturbance is a silent enemy that only appears after along period of continued stress. The National Institute for Occupational Safety and Health (NIOSH) reported that computer operators, who view their Video Display Terminals, report more eye-related problems than non- Video Display Terminals office workers and also indicated that visual symptoms occur in 75-90% of Video Display Terminals workers with 22% of Video Display Terminals workers have musculoskeletal disorders. A survey of optometrists indicated that 10 million eye examinations are annually given in American country because of visual problems at Video Display Terminals. This study delineated the series of symptoms which eventually known as Computer Vision Syndrome (CVS). This condition most often occurs when the viewing demand of the task exceeds the visual abilities of the Video Display Terminals user. The American Optometric Association defines computer vision syndrome as that complex of eye and vision problems related to near work which are experience during or related to computer use. The symptoms can vary but mostly include eyestrain, headaches, blurred vision (distance or near), dry and irritated eyes, slow refocusing, neck and or backache, light sensitivity and double vision. Using computers for long hours put repetitive stress on body, muscles and joints especially to eyes. Problems related to eyes affect all those who spend a significant time working with computers. There are many IT professionals who spend most of their time in front of computer screen are at risk of computer vision syndrome. The computer technology has its own pros and cons, the majority of these issues are related to health. The increased use of computers in the workplace has brought about the development of a number of health concerns. Many individuals who work at a computer Video Display Terminal reports a high level of job related complaints and symptoms including ocular discomfort, muscular strain and stress. The level of discomfort appears to increase with the amount of video display terminal use. Visual discomfort and related symptoms occurring in Video Display Terminal workers must be recognized as a growing health problem. Lutron, (1998). NEED FOR STUDY: Computer Vision Syndrome holds the distinction of being called the number one occupational hazard of the 21st century. Prevention of injury and illness is obviously, the best approach, but comprehensive health care and safety programs can help to reduce corporate sectors workplace injuries, absenteeism or presenteeism and related expenses. A fitness program was designed to reduce the symptoms of computer vision syndrome in software professionals. A pre and post-test study was conducted to evaluate the effect of the fitness program. The study revealed that the fitness program helped to reduce the symptoms of computer vision syndrome in software professionals. Namrata Arora Charpe and Vandana Kaushik, (2009) According to National Association of Software Companies, (2006) reported that number of workers is rapidly growing in information technology (IT) sector. Around one million computer professionals are graduating from various courses every year. While 10% of the work force was using computer for their occupational activities in 1980s, the percentage of users is expected to reach 100 million by the end of the 21st century. A National Survey of Doctors of Optometry (NSDO), (1997) reported that more than 14% of the patients present with eye or vision related symptoms resulting from Video Display Terminals work. The most common symptoms are eyestrain, headache, blurred vision, and light sensitivity, double vision, and color distortion. High visual demands of Video Display Terminals work make many individuals susceptible to the development of eye and vision related symptoms. American Optometric Association (2001) has reported that 90% of computer users had visual problems and 10% had musculoskeletal fatigue and also stated that there is an increase in employee complaints about computer vision syndrome. Despite the fact that 99.99% of the risk factors are 100% preventable, no concrete efforts are taken to ensure computer workers health. Majority of population involved in computer related jobs, no significant research in computer related health problems has been carried out in India as compared to Western countries. The computer vision syndromes remain under estimated and poorly understood issue at the work place. The general public, health professionals, the government and private industries need to be educated about this computer vision syndrome. Therefore there is a need to have a comprehensive study on the subject in order to create awareness and diminish the risk factors in the industry. Modern nursing focuses on holistic approach. It involves teaching in all aspects of health. Nurses have the responsibility in this advanced world of technology to identify the symptoms of Computer Vision Syndrome and to create awareness regarding the management of such problems among computer professionals. So, the researcher felt that it is one of the responsibilities of the community health nurses as a health care professional to start creating awareness among people who are at risk for developing Computer vision syndrome and also believes that the present study will be a stepping stone in this direction.

CHAPTER II REVIEW OF LITERATURE Review of literature is a systematic identification, selection, critical analysis and written description of related materials pertaining to the area of study or topic of interest to expand existing knowledge or to develop new knowledge Polit and Hungler,(2006). The related literature of the present study is organized and presented as follows: Section-I: Studies related to incidence and prevalence of Computer vision syndrome. Section-II: Studies related to risk factors and causes of Computer vision syndrome. Section-III: Studies related to signs and symptoms of the computer vision syndrome. Section-IV: Studies related to Preventive aspects of Computer vision syndrome. SECTION-I: STUDIES RELATED TO INCIDENCE AND PREVALENCE OF COMPUTER VISION SYNDROME. Mohamed Mabrouk Abdelaziz, et.al., (2009) conducted a study on the incidence and degree of visual defects among computer users. In this study, 100 subjects (50 computer users and 50 non computer users) were taken. Using standard Snellens chart and Ishihara chart, visual acuity and colour vision tests were conducted. When compared to non computer users, the visual acuity of computer users showed a significant decrease (P Banibrata Das and Tirthankar Ghosh, (2010) conducted a s study to assess the prevalence of musculoskeletal and visual disorders among the visual display terminal. The study was conducted in the different office premises in Kolkata. After selections of the locations, 100 visual display terminal (VDT) workers are selected randomly comprising 50 male and 50 female. A detailed study based on a modified Nordic questionnaire was performed among these visual display terminal workers for study period to measure the outcome of epidemiological studies on musculoskeletal disorders. The result of the study was that the Lower back problem is the main problem among visual display terminal workers. The both male and female visual display terminal workers also suffered pain in neck, shoulder, fore arm, wrist, elbow and the different parts of the upper extremities. This study revealed that the female visual display terminal workers suffer more discomfort feeling than male visual display terminal work ers. In this study, it was clearly mentioned that the discomfort feeling was relatively high among the aged visual display terminal workers. The prolonged period of work in an uncomfortable posture mainly lead to discomfort feeling among the visual display terminal workers. Another finding of this study was that both male and female visual display terminal workers suffered from visual stress due to prolonged period of work and without using of antiglare screen in a monitor. The conclusion of this study was the visual display terminal workers suffered pain mainly in the upper extremities and lower back of the body. They also suffered from visual stress. Females have a higher discomfort feeling than male visual display terminal workers. Mohamed Ali .K and Sathiyasekaran B.W.C, (2006) conducted a study on the prevalence of Carpal Tunnel Syndrome among computer professionals and risk factors. There were 648 subjects were selected from 4,276 computer professionals from 21 companies with a simple random sampling method. Carpal Tunnel Syndrome was diagnosed based on clinical features. The prevalence of Carpal Tunnel Syndrome was found to be 13.1% (95% CI 10.5-15.7%). Subjects with over 8 years of computer work, over 12 hrs of work per day and system administrators were at a higher risk for Carpal Tunnel Syndrome (OR 3.3, 4.9 and 2.5 respectively). Flexed or extended hand position had higher risk for Carpal Tunnel Syndrome. Higher risk for Carpal Tunnel Syndrome was found with higher exposure to computer work. Ergonomic considerations are important in facilitating proper positioning of hand while working with a computer. Richa Talwar, et.al., (2009) conducted a study to assess the prevalence of health disorders among computer professionals and its association with working environment conditions. The study design was cross sectional. There were 200 computer professionals taken as sample size from Delhi which included software developers, call centre workers, and data entry workers. The prevalence of visual problems in the study group was 76% (152/200), and musculoskeletal problems were reported by 76.5% (153/200). The result of the study exposed that there was a gradual increase in visual complaints as the number of hours spent for working on computers daily increased and the same relation was found to be true for musculoskeletal problems as well. Visual problems were less in persons using antiglare screen and those with adequate lighting in the room. Musculoskeletal problems were found to be significantly lesser among those using cushioned chairs and soft keypad. A significant proportion of the compu ter professionals were found to be having health problems and this denotes that the occupational health of the people working in the computer field needs to be emphasized as a field of concern in occupational health. SECTION II: STUDIES RELATED TO RISK FACTORS AND CAUSES OF COMPUTER VISION SYNDROME Izquierdo JC,et.al., (2007) conducted an observational study to identify the risk factors leading to the computer vision syndrome . Twenty-eight participants answered a validated questionnaire and had their workstations observed. The questionnaire evaluated the personal, environmental, ergonomic factors and physiologic response of computer users. The distance from the eye to the computers monitor (A), the computers monitor height (B), and visual axis height (C) were measured. The difference between monitor height and visual axis height was calculated and labeled as D. Angles of look to the computer monitor were calculated using the formula [angle=tan-1(D/A)]. Angles were divided into two groups participants with angles of gaze ranging from 0 degree to 13.9 degrees were included in Group 1; and participants gazing at angles larger than 14 degrees were included in Group 2. Statistical analysis of the evaluated variables was done. The findings of this study revealed that computer users in both groups used more tear supplements (as part of the syndrome) than expected. This association was statistically significant (p Zairina A. Rahman and Suhaila Sanip, (2011) conducted a study to identify sociodemographic and computer related predictors for computer vision syndrome .Computer vision syndrome (CVS) is an eyes and vision problems related to the activities that experienced in relation to the use of computer. Cross-sectional study and face-to-face interviews and workstation assessment was done. The finding of this study revealed that 68.1% reported computer vision syndrome symptoms. Among the samples, only 19.3% of the respondents put their computer on computer table and 61.9% took at least 10 minutes rest while on continuous one hour computer work. Multivariate logistic regression analysis revealed that the predictors for computer vision syndrome were female (OR=2.3), age 7 hours per day (OR=2.01). and also the study concluded that the use of correction lenses and long duration on continuous computer work predispose a person to get computer vision syndrome . Resting their eyes in between continuous computer work will be helpful to reduce possibility to get computer vision syndrome. Rosenfield M, et.al., (2012) conducted a study on effects of induced oblique astigmatism on symptoms and reading performance on viewing a computer screen. The researcher recorded the symptoms of the computer user after a 10 minutes period of reading from a computer monitor either through the habitual distance refractive correction or with a supplementary of -1.00 or -2.00D oblique cylinder added over these lenses among 12 samples. The distance correction condition was repeated to assess the repeatability of the symptom and monitored the samples reading speed accuracy for the period of 10 min trial. The findings of the study revealed that there was no significant difference in reading rate or the number of errors between the three astigmatic conditions, but there was a significant change in the median total symptom scores for the 0, 1 and 2D astigmatic conditions being 2.0, 6.5 and 40.0 respectively (p Chu C, et.al., (2011) conducted a study to identify computer vision syndrome signs are particular to computer function, or merely a symptom of executing a continued near-vision job. There are thirty young samples those who are visually normal were requested to read text audibly either from a standalone computer or on a paper at a screening distance of fifty centimeter for a constant twenty minutes time. For the two sessions the text were used and then the size and contrast were matched. For the two situations, the target angle and luminance were alike. After the reading sessions were over, the samples were requested to finish the written questionnaire based on their level of visual discomfort in the work time. The result of this study disclosed by discriminating the computer and hardcopy situations and confirmed that there was a noteworthy dissimilarity in median symptom scores with consider to blurred vision in the work time. (time=147.0; period =0.03) and average symptom score (tim e = 102.5; period = 0.04). In the two cases, symptoms were elevated when the use of computer. Symptoms when the prolonged computer use was considerably poorer than those reported after hard copy fascination under identical examining situations. The result of this study helps the practitioners to optimize visual comfort and efficiency during computer operation. SECTION III: STUDIES RELATED TO SIGNS AND SYMPTOMS OF COMPUTER VISION SYNDROME. Ranit Kishore and Ashish Arya (2011) conducted a review on studies related to signs and symptoms of computer vision syndrome. Millions of people around the world are using the computers not only as a business tool but as a recreational product as well. Predictions indicate that fully more than 70% of the working population will be using computers by the year 2011. There are also approximately 820 million internet users, with an expected explosion of users to over one billon in the next few years. This heavy computer use leads to various problems related to eyes. According to the report over 100 million people in the United States today use computers. More than 50 percent experience eyestrain, headaches, blurred vision and other visual symptoms related to sustained use of the computer the result might be quite similar for India. This type of stress on the visual system can also cause body fatigue and reduced efficiency at work. The authors have tied to conclude some of the major illne sses which may come during normal working hours on a computer with some of the possible solutions of those problems. Loh K.Y and Reddy S.C, (2008) conducted a review on the various signs and symptoms related to the computer vision syndrome. The invention of computer and advancement in information technology has revolutionized and benefited the society but at the same time has caused symptoms related to its usage such as ocular sprain, irritation, redness, dryness, blurred vision and double vision. This cluster of symptoms is known as computer vision syndrome which is characterized by the visual symptoms which result from interaction with computer display or its environment. Three major mechanisms that lead to computer vision syndrome are extraocular mechanism, accommodative mechanism and ocular surface mechanism. The visual effects of the computer such as brightness, resolution, glare and quality all are known factors that contribute to computer vision syndrome. Prevention is the most important strategy in managing computer vision syndrome. Modification in the ergonomics of the working environment, patient education and proper eye care are crucial in managing computer vision syndrome. MiljanoviĆ¡ B, et.al., (2007) conducted a cross sectional study on the visual related dry eye syndrome. Four hundred and fifty samples in Womens Health Study and two hundred and forty samples were taken for this study. The supplementary questionnaire consists of symptoms of dry eye in daily activities and their problems while reading, working with computer, watching television etc.The result of this study exposed that 1/3rd of study samples had clinically diagnosed dry eye syndrome or rigorous symptoms and 2/3rd did not. Logistic regression was employed to observe associations of dry eye syndrome with reported dilemmas with daily actions in every group and grouped guesses using meta-analysis methods. Out of the samples, eighty five percent completed the additional questionnaire, comprising one hundred and thirty five Womens Health Study and 55 Physicians Health Study participants with dry eye syndrome, and 250 Womens Health Study and 149 Physicians Health Study participants without dry eye syndrome. Controlling for age, diabetes, hypertension and other factors, those with dry eye syndrome were more likely to report problems with reading ([odds ratio] OR = 3.64, 95% [confidence interval] CI 2.45 to 5.40, P Barar A, et.al., (2007) gathered the data in the ophthalmologic literature from the Internet.. It was noted that the complex of eye and vision symptoms occurred due to prolonged use of computer and stress. The following are the recurrent complaints from the computer users i.e., blurred distance or near vision, neck and backache, dry and irritated eyes, eye-strain asthenopia, headaches, slow refocusing. In most of the developed countries, there are recommendations issued by renowned medical associations with regard to the definition, the diagnosis, and the methods for the prevention, treatment and periodical control of the symptoms found in computer users, in conjunction with an extremely detailed ergonomic legislation whereas in developing countries like India, it is necessary to rouse the interest of ophthalmologist colleagues in understanding and recognition of these symptoms and in their treatment, or at least their improvement, through specialized measures or through the coopera tion with specialist occupational medicine colleagues. SECTION IV: STUDIES RELATED TO PREVENTIVE ASPECTS OF COMPUTER VISION SYNDROME Ostrovsky A, et.al., (2012) conducted a study on effects of job related stress and burnout on computer vision syndrome among high tech workers. 106 samples were included in this study. All participants completed self-report questionnaires including demographics, computer vision syndrome, and satisfaction with work environmental conditions, job-related stress and burnout. The finding of this study revealed that there was a significant between-group difference in the intensity of computer vision syndrome, but not in its frequency. Burnout appeared to be a significant contributing factor to the intensity and frequency of computer vision syndrome and also the study showed that burnout is a significant factor in computer vision syndrome complaints among high-tech workers. The study concluded the ergonomic impact to improve health, safety and comfort of the working environment among computer users, for better perception of the job environment. Gangamma.M.P, et.al., (2010) conducted a experimental study on computer vision syndrome and its management with triphala eye drops and SaptamritaLauha tablets. There were one hundred and fifty one patients were taken for this study. From this, one hundred and forty one finished the treatment. Forty five patients had been advised to take Triphala eye drops in Group A; Fifty three patients had been advised to take the Triphala eye drops and also prescribed them to take internally SaptamritaLauha tablets. Forty three patients had been suggested to take the placebo eye drops in Group 3. The result of the study exposed that there was a significant progress with triphala eye drops in the computer vision syndrome management and also improvement in 48.89, 54.71 and 06.98% patients in groups A, B and C with triphala eye drops and saptamritaLauha tablets. Richardson.S, (2007) conducted a cross sectional study on computer related upper limp pain and computer vision syndrome in Malaysia. In this study, there were one hundred and thirty six computer users were taken as samples who were the University students and office staff. A rapid upper limp evaluation for the office method was employed for assessment of work-related overuse syndrome. The frequency of computer vision syndrome was reviewed by including a 10-point scoring system for every of its different symptoms. The result of this study disclosed that many were using typical keyboard and mouse without a few ergonomic changes. About 50% of them had a little low back pain as of not having an modifiable backrest. Numerous users had higher scores of the wrist and neck recommending raised hazard of increasing occupational overuse syndrome, which required additional interference. Several (64%) were utilizing refractive corrections and still had high scores of computer vision syndrome comm only including eye fatigue, headache and burning sensation. The increase of computer vision syndrome scores (suggesting more subjective symptoms) correlated with increase in computer usage spells. The study concluded that further onsite studies are needed, to follow up this survey to decrease the risks of developing computer vision syndrome amongst young computer users. Yee.R.W, et.al., (2007) conducted a research in signs and symptoms of computer users and preventive measures. The researcher also assessed the eye related problems through the clinical tests for prolonged computer users. There were 40 samples taken for this study for three hours in a day. The scores had been computed based on Ocular Surface Disease Index. The assessment had been done based on the scores. The samples were requested to play the computer games for half an hour and the 4 treatment had been applied in the random order i.e artificial tears, MEGS, no treatment, artificial tears with MEGS(microenvironment glasses). Once the sessions were over, the samples were requested to answer the questionnaire. The result of the study exposed that there was a noteworthy association found in the in the index value. The p values were calculated. They were constantly dissimilar in fluorescein and lissamine green discoloration with P>0.05. There was a noteworthy improvements in the scores an d TBUT(Tear breakup time) and also there was a steady development of progress in lissamine green staining and in fluorescein staining. The computer users those who have ocular complaints should went for ocular surface examination and they were treated with separation of environmental manipulations, ocular surface and artificial tears. Shirley Telles, et.al., (2006) suggested that the yoga practice appeared to diminish visual anxiety. Dry eye occurs due to computer vi

England rural life Essay

â€Å"Out, Out†Ã¢â‚¬Ëœ is about childhood in rural New England. It shows how children had to work in the late 1800s and early 1900s when Robert Frost was a young boy. The poem illustrates a negative image of growing up in the rural life of New England. It demonstrates how quickly and unexpectedly death can happen, but, also, the harsh fact that life has to go on.  The title of the poem ‘†Out, Out†Ã¢â‚¬Ëœ is a quotation from William Shakespeare’s play ‘Macbeth’. It is taken from Macbeth’s soliloquy after his wife (Lady Macbeth) kills herself, and he reflects on the brevity and pointlessness of life:  Ã¢â‚¬ËœOut, out, brief candle!’ It is significant to this poem because Frost is also reflecting on the futility and shortness of life through the loss and the innocence of the child, which is illustrated through the emergency and alarm in the boy’s pointless plea:  Ã¢â‚¬ËœDon’t let him cut my hand off-‘  The poem is written in blank verse, using the iambic pentameter of ten syllables per line to imitate in the natural rhythm of speech.  At the beginning of the poem Frost uses personification of the buzz saw to create an effective opening, which is furthered by the unpleasant sounds of the onomatopoeic snarling and rattling – giving the buzz saw a frightening image, and creating a vivid negative representation of rural life in New England. Frost contrasts this first impression with the imagery of ‘sweet scented stuff’ that is blown by the breeze, and his ironic statement that ‘nothing happened’, which effectively leaves the reader unprepared for the followin g events. Frost dramatically shows how dangerous life working in rural New England can be when the boy has his hand cut of by the saw, which is sinister on its own, but the sombreness of the situation is heightened by the saw being personified even more:  Ã¢â‚¬ËœÃ¢â‚¬ ¦ the saw,  As if to prove saws knew that supper meant,  Leaped out at the boy’s hand’  When the boy’s hand is lost, Frost uses repetition of ‘hand’ to emphasis the hardship of how young children were expected to work from such a young age. This point of working children is further pointed out when the boy’s work is compared to a man’s:  Ã¢â‚¬ËœDoing a man’s work, though a child at heart-‘  From this the reader can see how hard life was to grow up in rural New England. As the poem ends, it appears more sinister as Frost reflects on the young boy dying and the pointlessness of life through the illustration of sinister words such as ‘the dark of either’. The dashes create effective pauses as the boy takes his last breath, helping to highlight the hardness of rural life to the reader. ‘Little-less-nothing!-and that ended it.’  The tone of the poem is relaxed and casual in the beginning, but changes after the boy’s sister tells them ‘†Supper.†Ã¢â‚¬Ëœ The tone becomes tenser and appears to be insensitive due to Frost’s bluntness about death.  Ã¢â‚¬ËœAnd they, since they  Were not the one dead, turned to their affairs.’  However, Frost is stating the harsh fact of life – that it has to go on for people to survive, even after a terrible grievance. I think this fact is particularly true for rural life in New England at this time. This is because farms still had to be looked after to ensure the farmer got money to support himself and his family, therefore, they could not afford to stop everything – it was not that they did not care about the death of the young boy. The sinister tone of this poem is contrasted to the more light-hearted poem, ‘Birches’. Through ‘Birches’, Frost is reminiscence about his childhood and is thinking about a simpler and easier time in his life. The poem outlines the innocence of being a child and illustrates how harsh life can be as an adult.  Ã¢â‚¬ËœBirches’, like ‘†Out, Out†Ã¢â‚¬Ëœ, is written in blank verse, using the iambic pentameter of ten syllables per line to imitate in the natural rhythm of speech.  In comparison to the previous poem (‘†Out, Out†Ã¢â‚¬Ëœ) ‘Birches’ shows the more positive yet still some negative aspects of life in rural New England. It positively represents a fairly straightforward time for Frost, a time when he was able to conquer the trees:  Ã¢â‚¬ËœAnd not one but hung limp, not one was left’  The repetition of ‘not one’ in this quotation emphasises his success in climbing the birch trees. His use of alliteration on the ‘k’ sound helps describe the skill needed to conqu er the trees in this way. Climbing carefully  with the same pains you use to fill a cup ‘  In the poem Frost shows how rural life in New England can be lonely for a young boy, which shows a negative aspect to rural life in New England.  Ã¢â‚¬ËœSome boy too far from town to learn baseball  Whose only play was what he found himself’  Furthermore, this vividly shows how rural children were more independent and able to amuse themselves, but it does show how they were very isolated from other children with no-one to play in the birch trees with.  For Frost, the birch trees are a way to escape the pressures of being grown up. The poem shows how he is yearning to climb the birch trees once again and metaphorically escape from the earth. ‘I’d like to go by climbing a birch tree’  The poem has a casual tone, just as ‘†Out, Out†Ã¢â‚¬Ëœ but ‘Birches’ maintains this casual and relaxed tone throughout unlike ‘†Out, Out†Ã¢â‚¬Ëœ which changes to a more sinister tone. The tone of ‘Birches’ does become more when Frost personifies fate to misunderstand him:  Ã¢â‚¬ËœMay no fate wilfully misunderstand me’  Although the tone of ‘Birches’ becomes more philosophical it still maintains a casual tone. The casual tone in ‘Birches’ of the poem is captured by the colloquial language that is used. ‘But I was going to say . . .’  After reading and studying both ‘†Out, Out†Ã¢â‚¬Ëœ and ‘Birches’ I prefer ‘Birches’ as I feel it makes rural life in New England more vivid. I think ‘†Out, Out†Ã¢â‚¬Ëœ is a more sinister and negative approach to look upon rural life. But, Frost illustrates a more vivid image through the use of alliteration throughout ‘Birches’ which creates a more real and vivid representation than ‘†Out, Out†Ã¢â‚¬Ëœ.

First Amendment to the United States Constitution Essay

We live in a society where we pride individuality and staying true to who we are, but contradictingly enough we have large numbers of minorities being discriminated for being who they are. Racism being a strongly relevant issue, even in our day and time, doesn’t get dealt with as seriously as it should. Charles R. Lawrence III takes a firm stand addressing this issue arguing that racist speech should be regulated in universities rather than be protected by the first amendment. He claims that universities need to regulate racist speech in order for their students to really receive the equal educational opportunity they deserve. Getting rid of racist speech would be the only way to give all students the equal opportunity to learn and participate in their university. Lawrence makes strong claims in his argument; however, a lot of his argument is supported through his writing techniques. Charles Lawrence in his argumentative essay â€Å"On Racist Speech,† implements emotion-provoking diction, subtle figurative language and a thoughtful use of detail in order to effectively dispute the need for the regulation of racist speech. In his essay, â€Å"On Racist Speech,† Lawrence argues that universities should regulate racist speech. He points out that when racist speech involves insults, catcalls or assaultive speech, it becomes â€Å"fighting words,† which have been declared by the Supreme Court to not be protected under the first amendment of free speech. Lawrnence argues that racial insults shouldn’t be protected by the first amendment anyway because, the speakers intentions aren’t to â€Å"discover the truth or to initiate dialogue, but to injure the victim†. He also says that the need for regulations on racism advocated under the university’s responsibility to offer equal educational opportunity. Students don’t have the equal opportunity to learn and participate when they are crippled by the fact that at any time they could be struck with verbal harassment or assault. Lawrence offers a counterargument saying how free speech is the lifehood of our democratic system and that it is impossible to outlaw racist speech without suppressing other kinds of speech necessary for our democratic society Using certain words with specific emotional appeal, Lawrence effectively draws emotion out of the reader and strengthens his argument putting the reader at an emotional, personal level with the argument. For example, he first mentions how â€Å"we will be forced to combat [bad speech]† (51). He specifically chooses to use â€Å"combat,† a word with a far more aggressiveconnotation and weight, rather than a more passive word such as address. By doing so Lawrence expresses to the reader the urgency and grave seriousness of the situation; how racist speech is an actual, reckonable force that nees to be contended with. Also, he depicts the matter to be a â€Å"cry† from â€Å"victims† with â€Å"injuries† and â€Å"burdens,† all words with implied emotional context (51, 54). Just by picking certain words, Lawrence successfully uses pathos, pulling the emotions out of the reader and making them feel pity for the minorities. Ultimately with the right words, Lawrence makes the minorities more than just demographics; they become a group of people pressed under injustice and in need of help. He essentially, uses diction to play the readers heartstrings in a manner to make them feel sympathy for the minorities and further sway the reader to support his argument. Lawrence implements figurative language providing material from which the reader can mentally draw an image or feeling from, by which he further intensifies his argument, and ultimately making it more real and relatable. For example, he describes racism to have â€Å"rising flames† in the beginning of his essay (51). He draws a parallel between the situation of racist speech and an out of control fire. By painting such a strong image, he expresses the severity of the issue as well as how it must be addressed urgently. Rising flames aren’t something to shilly shally around with; likewise, neither is the problem of racist speech. Another example is when he describes the â€Å"use of words as assault weapons† (54). By comparing words, simple means of expressions, to assault weapons, firearms meant to hurt, he suggests the brutality of the issue. By putting racist speech next to weapons of destruction, Lawrence effectively shows how racist speech has actual ramifications that hurt and damage others. Also by giving this comparison, he’s able to put a nasty, cruel feeling in the reader’s mind, a feeling that would really stick with them. Lawrence’s use of figurative language proves to be very effective in getting to the reader, because it puts images, and consequently feelings, in the readers mind. He manages to give actual substance to the argument, substance the reader can see or feel. Lawrence sensibly avoids expounding upon the particulars of â€Å"racist speech,† which would have added smaller, more complicated arguments, and ultimately added extra baggage that could turn away readers. Touching upon sensitive issues of racism and free speech, he already packs a heavy load of content for the reader to digest and reflect upon. If he were to add more with what he believes racist speech should be defined as, he would risk losing readers, and not just to an overload of content. By providing a set definition, Lawrence would basically just be throwing out one more thing for the reader to possibly disagree with. Would his definition be too strict, he’d lose some rather more lenient readers and vice versa. Asserting more of his opinion would have created more room for disagreement with the reader, especially when discussing such touchy subjects. Drawing boundaries of racist speech would have just made his controversial essay more controversial. Lawrence having already sensitized the reader talking about â€Å"racial violence† on â€Å"victims† with â€Å"injuries† and whatnot, portrays his argument to be more than just a cold expression of his opinion. Having evoked the reader’s emotions, he had to consider them, making sure not to say something too sensitive that would really strike the reader. By leaving the definition open to the reader, not only does he allow the reader to create their own stand on the issue, where they could personalize it and make it relatable to their lives, but he avoids coming off as overbearing which would have been a clear turn off to readers. Also, by steering clear of precarious details, Lawrence is able to really stick the nitty gritty to the reader and just get his argument out there and heard to a wider array of audiences. Lawrence effectively uses rhetorical devices such as diction, figurative language and details in favor of his argument to regulate racist speech. As serious and urgent Lawrence calls for the regulation of racist speech is, realistically it seems impossible. â€Å"Racist speech† is far too subjective of a matter to have any form of regulation. Plus, it would be impossible to outlaw racist speech without suppressing other speech. That however, does not dismiss the issue. We should rather confront the issue on smaller levels and address it from the source—ourselves. Simply if we were all to simply just stop making or encouraging racist remarks, whether that be indirectly or just for laughs, there would no need for racism to be regulated. If we all were to progress to be accepting of all races, racism would just plainly be a thing of the past.

The Color Chemistry That Makes Mars Red

When you look up in the sky, you can recognize Mars by its red color. Yet, when you see photos of Mars taken on Mars, many colors are present. What makes Mars the Red Planet and why doesnt it always look red close-up? The short answer for why Mars appears red, or at least red-orange, is because the Martian surface contains a large amount of rust or iron oxide. The iron oxide forms a rust dust that floats in the atmosphere and sits as a dusty coating across much of the landscape. Why Mars Has Other Colors Up Close The dust in the atmosphere causes Mars to appear very rusty from space. When viewed from the surface, other colors are apparent, in part because landers and other instruments dont have to peer through the whole atmosphere to see them, and partly because rust exists in colors other than red, plus there are other minerals on the planet. While red is a common rust color, some iron oxides are brown, black, yellow and even green! So, if you see green on Mars, it doesnt mean there are plants growing on the planet. Rather, some of the Martian rocks are green, just like some rocks are green on Earth. Where Does the Rust Come From? So, you may be wondering where all this rust comes from  since Mars has more iron oxide in its atmosphere than any other planet. Scientists are not completely sure, but many believe the iron was pushed up by the volcanoes that used to erupt. Solar radiation caused atmospheric water vapor to react with the iron to form iron oxides or rust. Iron oxides also may have come from iron-based meteorites, which can react with oxygen under the influence of solar ultraviolet radiation to form iron oxides.
