Stereotypes in the Media free essay sample

Results interpreted showed news stereotypes are considered more socially acceptable, whereas comedy stereotypes can be viewed as offensive and not suitable for children. Drama was very similar to comedy. Stereotypes and their Pervasiveness in the Media The media these days is littered with stereotypes. These stereotypes portray a multitude of different categories, such as age, race, religion, sex and sexuality, mostly in a negative light. The aged, for example, have bad hearing; Muslims are all violent and suicidal; and the French have a snobbish attitude, love for frogs legs, and a hate for the English. While stereotypes tend to have a grain of truth within them (the French really do hate the English), they tend to overlook the differences between individuals, making them too generalised and unreliable. Despite this inaccuracy, the media still does this often. While stereotypes are used in comedy â€Å"for the lulz,† they are deliberately used in this manner, unlike in certain news and current affairs shows, where it is used out of ignorance and efficiency. We will write a custom essay sample on Stereotypes in the Media or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Because of the way media has stereotyped minorities, society has absorbed this into everyday use and many find it socially cceptable to use offensive stereotypes in everyday conversations. While comedy shows are not trying to offend and proliferate stereotypes, they in fact cause more harm than news and current affairs programs. The Simpsons, a television show known well for its satirical voice and comedic social commentary, is scattered with stereotypes, many of immigrants. Apu, an Indian convenience store owner who appears often in the show, is stingy and has a recognisably Indian accent and prays to his Hindu god, Ganesh. This inaccurate portrayal of Indian immigrants is perceived to be humourous by the public, but they are likely to apply these stereotypes to real people if their misconceptions are not corrected. This research aimed to compare the frequency of stereotypes between different genres of prime time television shows. The genres compared were comedy, drama and news. The hypothesis is that comedy will have the most stereotypes, followed by news, then by drama. Method Participants The participants in this investigation were 36 fifteen to sixteen year olds in year 11 of high school. The students were all academically selective and were mostly Caucasian. The participants chosen were all psychology students, taught by the same teacher. Parents had given permission to participate in this research and signed a permission slip for students to watch at least 3 prime time television shows within two weeks, one to be news or current affairs, the other two being of their choice. Apparatus A log sheet was given (see appendix A) to record the amount of time watching television, and the number of stereotypes noticed. Televisions were to be provided by the participants. So were pens. Procedure The 36 participants were instructed to watch television between the hours of 5 and 10pm. While watching television, they were to record the number of times they saw a stereotype being portrayed and comment on what was being portrayed. This took place over two weeks, after which the results were collated and analysed. Results The results are shown in chart form in Appendix B and C. Once the results were graphed there was not much of a difference between the genres. The data in the graph is collected from a number of participants’ log sheets. 30 people watched news, 21 watched comedy, and 19 watched dramas. The graph didn’t show a single genre to contain significantly more stereotypes. [pic] The graph above shows that there seems to be less of a gap between different stereotypes in comedy, while news has more stereotypes of age and less of religion. Drama has less stereotypes than the others, even when the lack of viewers is factored in. Race and gender are the stereotypes most portrayed by television. Discussion The data partially supports the hypothesis. Despite drama being the genre of television with the least stereotypes, comedy came second to news. News portrayed a lot more stereotypes of age. This is probably a result of violent attacks on old people in their homes. The least portrayed were sexuality, most likely a result of complaints of sexually explicit material being aired. The results do show a large amount of stereotypes are present in television shows. The stereotyping has a tendency to make things quicker and less time-consuming. After all, how is it possible to list all the political, social, economic, ideological and theological differences of a population of about 6 billion? The accuracy of this investigation is to be questioned. While it is possible to rely on this data, it is not going to be completely accurate and it may not demonstrate the true amount of stereotyping done on television. If, for example, all the news shos watched were from the same network, this would affect the results. Other networks may be more biased or even more impartial. The lack of regulation of the programs and networks would have had some effect on the accuracy of the results. Also, the method of recording the stereotypes might also affect the results. With a very vague system, it is impossible to be exact on what stereotypes are displayed, and whether they are a simple comment on turbans, or a full-fledged attack on the habits of old people. Very little research has been done into the number of stereotypes portrayed on television, as opposed to countless studies into the harmfulness of these stereotypes on impressionable children and even adults. The research shows that there are a lot of stereotypes on television, at least 5 or 6 per program. This research is part of understanding how television networks design their shows, and how stereotypes are used as they are instrumental to making changes to unfair depiction of minorities in the media. If the stereotypes are deemed inappropriate then it would be unlikely to make things any better when it comes to international relations and even domestic relations. There has been a lot of rage aimed at the Australians who assaulted two Indian students in Sydney. The acts of violence against minorities have escalated recently. Further research may venture into stereotyping of specific minorities, to examine the details of stereotyping.

Health Issues of a Developed Country (The US) The WritePass Journal

Health Issues of a Developed Country (The US)   Abstract Health Issues of a Developed Country (The US) prescription charges are at 7.65  (Politics .co.uk, 2012).   Widespread protests against the prescription charges have contributed to several exceptions in the prescription drug charges including for children under 16, pregnant women, elderly people above 60, etc. More recently people with chronic conditions such as cancer have been included into those under the exempted category. While in Wales and Northern Ireland prescription charges have been completely abolished, the English government has, however, indicated that no further free prescription programs would be introduced but that the new policies would focus on brining more fairness into the prescription charging system (Politics.co.uk, 2012). Transition to a Market System Chronic underfunding and gaps in services and the pressures to improve the overall operating efficiency have gradually led to the NHS from being a total public ownership entity towards a market based system. In fact this shift towards a market based system could be traced way back to the Thatcher administration that introduced the policies of ‘general management’ and ‘outsourcing’ which bought about a fundamental shift.   General managers were people who were specialized in hospital management and provided a neat layer of interfacing between the health policy makers and the doctors and nurses who implement the policies. Outsourcing of non medical services such as hospital cleaning, catering saw for the first time the entry of the private sector into the NHS system (DH, 2005). Since then private sector participation in the NHS has improved significantly. By the late 1990’s, for instance, long term care by NHS was already taken over to a large extent and managed by private for profit service providers. Long term elderly care is no longer free of cost. Increasing private participation could be inferred from the statistics that from over 137,200 residential care homes in 1985 the numbers had dropped to 64,100 by 1998 (BBC, 1999).   Elderly care in these settings is not free and is totally means based with those earning more than  £16,000 per annum having to bear the entire expenses while the state provides maximum assistance for those under  £10,000 categories. NHS Spendings review points out that between 1998 and 2010 there was an average 5.75%   increase in health expenditure while the NHS is slated to receive .4% real terms growth between 2010 and 2014. This indicates the degree of financial pressure under which the NHS is operating. As (Appleby et al, 2009) points out, the pressure on NHS will continue to increase with growing challenges due to a mixture of factors including an aging demography, high cost pressure of new medical technologies, and the expectation for higher quality standards.   It is estimated that the NHS has to make considerable cost cuttings by way of improved operational efficiency to the tune of    £15 to  £20 billion in order for it to be able to continue providing equitable access to healthcare services to all the citizens(Nicholson, 2009). It is under these dire circumstances that the UK government proposed some fundamental structural and functional reforms to the NHS that are listed in the white paper ‘Equity and Excellence: Liberating the NHS’. One of the fundamental changes to the organization of the NHS as listed out in the White paper is the devolution of the ‘Primary care Trusts’ (PCTs) (Nuffield Trust, 2010). The PCTs which were instituted in 2002 to supervise primary care provision is no longer a valid entity. Its function has been taken over by Clinical commissioning groups (CCG) comprising mainly of local GPs. The idea behind such a reform is to increase local empowerment. Furthermore the PCTs were in the past struggling with frequent restructuring. One of the underlying motives behind such a transformation is to place greater responsibility with the local GPs as they are directly involved in service referrals. Also since GPs are directly involved in both commissioning and care provision they are better positioned to make effective assessments and to prevent unnecessary hospitalization and other services. In other words, the establishment of the GP consortia which is one of the highlights of the ‘ Equity and Excellence: Liberating the NHS’ white paper, is expected to increase the integration between the GP’s , specialists and other service providers paving way for an integrated care delivery mechanism that is both cost effective and efficient. Furthermore, the white paper also refers to the formation of a NHS commissioning board that supervises the overall equitable access to NHS services, commissioning, and the proper allotment of resources. This would ensure that micromanagement is not an issue at the NHS. The new policy framework also dissolves several quangos thereby resulting in greater operational savings. By these means the new reforms are slated to save up to 20 billion in terms of efficiency of operations by 2014.   Projections indicate that up to 45% savings could be realized in the form of management related cost savings (DH, 2010, pg 5). One of the distinctive factors of the current NHS reforms compared to the original NHS policies is the shift from a purely public system towards a more market centric healthcare system. The focus on increasing the participation of the patient and providing them the choice as to their service providers and the treatment that they want are particularly prominent aspects of the new healthcare bill. . The inclusion of the ‘choice of any willing provider’ in the ‘Health and Social Care Bill’ lays stress on the increased freedom for the health consumer (DH, 2010, pg 17). It also emphasizes the increasing competition among contracted health service providers which is ultimately good for improving the overall quality of health care delivery. Reduction in bureaucratic control and empowerment of the care providers imply that the primary care providers’ could function independently and effectively to meet the needs of the patients. Effective monitoring is the key to any functional system. For a huge organization such as the NHS monitoring the functioning of the various agencies and systems is very vital for achieving streamlining of operations, process efficiency and achieving high quality of care. One of the key aspects of the new reforms is entrusting local health watch organizations with the responsibility of managing and addressing the feedbacks from the health consumers. These organizations also support the patients in making their decisions about service providers. These organizations will directly report the performance measures of service providers and patient feedbacks to local as well as national authorities helping to address any consumer grievances and quality concerns at the earliest(DH, 2010, pg 19). While there are proponents for this new system there are also concerns expressed by politicians, professionals and general public who are worried that the competition between medical service providers would engender compromise on quality of services contrary to improving the same. This is particularly so when these decisions are made on the bidding approach and when lower cost of service provision is the main criteria. One particular instance is the drug and alcohol support services that are vastly privatized in the UK. These private organizations are paid  £3000 if the addicts are rehabilitated and remain free of drugs for 3 months and a further  £5000 if they remained drug free for a whole year. There are complaints that under these circumstances, in these private organizations, the focus is not entirely on rehabilitation and saving the patient is not the primary concern. As a case in point, an extreme heroin addict was just discharged from the clinic without any alternative in tervention. Methadone prescription for detoxification was not even tried as the private company would not be remunerated for such an intervention (Pemberton, 2013). . Furthermore since the entire drug and alcohol services is taken up by the private organizations there was no further referral or intervention possible for such cases. These are instances that point out the risks in adapting a privatized and highly fragmented setup.   Furthermore there are concerns that under the concept of ‘payment by results’ that is advocated under the new NHS policies, there is even more risk that the private agencies would just focus on achieving end points of care. While this approach would be okay for acute clinical conditions it leaves a lot to be desired in the management of chronic conditions where there is no visible endpoint. Conclusion From the time of its institution in 1948 to the current period, the NHS has undergone significant changes in its mode of operation. Presently, there is a distinct shift in healthcare focus as witnessed by a change from the fully public model of care delivery towards increasing private participation in the NHS system.   Growing elderly population and increasing strain on its health services have forced the NHS to adopt these new and novel approaches. These include a fundamental change in its mode of care delivery with the increasing private sector participation in care delivery. Though maintaining free point of access care delivery is one of the main mottos of the original 1948 NHS manifesto, the increasing health care consumption and cost pressures have, to an extent, compromised on this objective. Today many services such as prescription drugs, long-term care are no longer free and there is increasing private sector participation as contracted service providers. The purely fragmen ted approach of private sector service providers who are driven by a contractual obligation and cost centered focus, would definitely compromise the quality of services and the original advantages that the NHS offered.   While the growing needs and the changing demands have necessitated such drastic transformation of the NHS system, care should be taken in the form of having enough performance monitoring and quality checkpoints in place that ensure that private participation does not erode some of the fundamental strengths and qualities of the NHS, the most basic of which is to enable equity of access to quality healthcare.

Self - evalation Essay Example | Topics and Well Written Essays - 1250 words

Self - evalation - Essay Example In the absence of the person and nature of Jesus Christ as God incarnate, the message of Jesus would lose the uniqueness, authority and applicability to man attributed to it. The message of Jesus Christ in turn remains of crucial importance since liberation theology is centered on the message of Jesus Christ. As a sociopolitical movement which interprets the teachings of Jesus Christ as being relational and key to emancipation from adverse or oppressive economic, political and social conditions. For instance, the Sermon on the Mountain places great emphasis on the poor and the less privileged, and thereby setting stage for liberation theology, given that liberation theology is deemed by its proponents as an interpretation of Christian teachings and faith through the hope, struggles and suffering of the poor. Normally, liberation theology critiques the society perceived to be oppressive, interprets the Christian message, through the worldview of the poor and is done by detractors such as Christianized Marxists. In this light, it becomes clear to me, that Christianity is far much interested in man's liberation. Another insight that I gleaned from classroom situation was the liberating power of the message of Christ. This was exemplified in the manner Christianity has been able to break forces, institutions and walls of segregation such as the caste system in India, the color bar in South Africa and racial discrimination and the use of racial discrimination in America, particularly, the slaveholding South. The eradication of these walls of separation is in turn underpinned by the manner in which the Christian doctrine intermarries readily with concepts such as universal brotherhood. The concept of universal brotherhood in the Christian doctrine is rested not only on humanity drawing from Adam as the first parent, but also from Christ, the second Adam bringing humanity into newness of spiritual life and oneness in the family of God. Another value that I gained from the classroom experience is the anthropocentric nature of Christianity and its teachings. Even Levin points out that so integrally woven into the benefit and wellness of man that the Gospel of Christ and the Christian message rest upon man’s welfare. Christ gives out His life in His own volition to secure man’s eternal destiny. Secondly, although salvation that Christ secures for mankind is free and a work of God’s grace, yet the anthropocentric nature of the Gospel is to be manifest in man being benevolent towards his brother, as a testimony to his conversion. Mathew 25: 34-46 and James 2:14-26 underscore the importance of dealing benevolently with the poor and the less privileged in the society as assign of true conversation. Charitable foundations such as Henry Dunant’s Red Cross and Red Crescent, and initiatives such as the ones carried out by St. Francis of Assisi and Mother Teresa draw their inspiration from these lines of teaching (Levin, 25). Aga inst this backdrop, I can say confidently that the classroom experience has helped me gain a wider scope of the role Christianity plays in dispensing socioeconomic and political emancipation and empowerment.

Virtual Reality A Modern Technology Media Essay

Virtual Reality A Modern Technology Media Essay Virtual reality is one of the modern technologies which was introduced a few decades back and has taken an important place in the field of technology in a very short time. it makes use of an artificial environment generated by the computer in which simulates the real environment. Besides gaining an immediate acceptance in the world of computer games, it is now being used in many fields of life including architecture, medicine, military and aviation. Scientists and researchers are expecting to explore a lot in this modern technology than what we know about it today. It is a great leap in the field of 3D and a lot of work is still under progress. The discussion below is an insight into the details of this technology, its uses, advantages, disadvantages and social impacts. The term virtual reality refers to refers to a modern technology providing an immersive, interactive experience using the three dimensional computer based graphic images. This technology creates an artificial environment with the help of computer hardware and software and is presented to the user in way which simulates the real world. The equipment makes use of a pair of special gloves, ear phones and goggles, the three of them being controlled by the computer. In this way, three of the users five senses are receiving and input from the computer. The goggles also act by detecting the eye movements of the user, thereby monitoring his actions. ORIGIN: The idea of virtual reality was first presented in 1930s, when the first fight simulator was invented by the scientists for the purpose of training the pilots. This was in an attempt to prepare them for the actual flight environment before being able to fly a real fighter plane. The invention got improvement in 1965, when Ivan Sutherland, an American, presented his theory of developing a portable virtual world using two tiny television sets, one meant for each eye. His invention worked, but to a very basic level. The images were rough and not clear. Another problem was the weight of the helmet used. It was quite heavy and needed to be supported from the ceiling. But the idea has actually got its base and now needed to be improved. Scientist continued working on this idea until in 1985, Michael McGreevy, from NASA introduced a much improved version of virtual reality. It was light weighted, using motorcycle helmet with mini display screens. It was also provided with the special sensors which were used to detect movements with the help of sensitive computer technology. Finally, during 1986, the invention got its final touch when a computer games programmer named Jaron Lanier introduced a new glove for virtual reality. In this way took the modern form in which we look it today. (Virtual Reality, 2004) TYPES OF VIRTUAL REALITY: There are three main types of virtual reality technology: The first one uses a helmet, ear phones and a pair of special gloves or joy sticks controlled by a computer and assisted by special sound effects and graphic images. The second one makes use of the video cameras. These cameras track the image of the participant in an artificially created virtual world. The participant can even move the objects in this world using virtual technology. The third type makes use of the three dimensional images. The screen used is shaped in a curve. This makes the images closer to the real world. (Nigel W. John, Joanna Leng (2001). CATEGORIES: There are six categories in which virtual reality can be displayed: Desktop displays, Head-mounted displays, Arm-mounted displays, Single screen displays, Surround screen displays and Volumetric displays. (Nigel W. John, Joanna Leng (2001). The head mounted displays are among the most widely used displays for virtual reality. In this device, a pair of display screens is placed right in front of the users eyes. These screens are attached to a helmet which the user wears. The arm mounted displays resemble a pair of binoculars mounted on an articulated arm. The user visualizes the virtual world by means of lenses. His virtual environment is controlled by his movements at an arms length and range of motion. Single screen displays use the Immersive Workbench products. These products mostly make use of a tabletop metaphor where the virtual objects give an impression of lying on the table top. Other types of single screen displays make use of a window metaphor. In this kind of display the image seems to be appearing in a large window opened into a virtual space. Another sort of display is known as CAVE, where the viewer sees the images in the form of multiple screens surrounding him as if he is present inside a large cube. The viewer can explore the virtual world by moving inside the cube. (Nigel W. John, Joanna Leng (2001). USES: Virtual reality is now being used in many professions including architecture, meteorology, military, medical and molecular studies. 1. Architecture. Virtual reality has been now used for long in the field of architecture. It has been used to establish the models of buildings before the construction is started. It has also proved to be helpful to determine how a building may have collapsed and to provide improvements in reconstructing a damaged building. 2. Weather Forecast. Virtual reality has also been used in the weather forecast profession by simulating the images with the data collected from the satellites and radars. 3. Military Training. Now virtual reality has officially been declared a part of the U.S military training. They make use of the environments created using virtual reality in whole rooms where soldiers are provided different experiences. These include the war fields as well as different exercises. 4. Cancer Chemotherapy. Another remarkable use of virtual reality in medical field is as a treatment for the cancer patients. Chemotherapy is a painful procedure for most of the patients, yet it is necessary as many malignant cancers cant be treated but their progression can be stopped by the chemotherapy treatment. It has been shown that if the chemotherapy is provided to these patients while they indulge themselves in some activity using virtual world, the pain felt is quite less that that experienced without it. Many chemotherapy centers are now making use of this technology. It is especially true in case of children suffering with cancerous lesions requiring chemotherapy. They feel the procedure less painful if they are allowed to play games or perform any other activity using virtual world and receiving the chemotherapy at the same time. Researchers explain this by the fact that three of the users senses become occupied while using the virtual world. These include, vision, hearing and touch. Thus the brain is actually distracted from the painful event being carried out. Images also play quite an important role in this treatment. The patient is given the option to select any image of his/her choice, like walking on a beach, or visiting an art gallery or performing deep sea diving etc. 5. Molecular Biology. The molecular biology is also making use of virtual reality in order to study the molecular and cellular structures. It enables the scientists to visit small sections of a molecule and study its properties. 6. Medical Studies. Virtual reality is now being used in medical studies as well. By using virtual reality, the medical students and even doctors can learn complex medical procedures without risking anyones life. In medical field virtual reality has been used in diagnosing various diseases using the images provided by other scans and then merging them using medical technology. (eHow, 2010) 7. Driving Lessons. In many countries now virtual reality has been used for driving tests as well. Apart from the actual on-road driving test, the candidates have to take a virtual reality based driving test as well which simulates the real environment. 8. Disabled Children. Virtual reality has also proven itself to be a blessing for the disabled children. A child who a wheel chair for moving needs around can gain an insight of many of the places which he cannot otherwise visit. He can select the images or environment of choice and go to the virtual world for flight, diving, walking, fighting, driving or many other activities. In this regard it is a great blessing for the bed ridden or wheel chair bound children or individuals. (itgs, 2010) ADVANTAGES AND DISADVANTAGES: The main advantages of virtual reality are as follows: Virtual reality provides the diverse types of data available in instant forms. It provides images from many different points of views. It is able to demonstrate the non-visible data to the user like in case of geochemistry. Allows a person to visit the places normally inaccessible to individuals. Provides an experience which can be repeated and revised. It can cover the education and knowledge related to almost all fields of life. Even children as well as adults can get benefit from it. It provides information in an interesting manner preventing the user from getting bored. (Weili Qiu, Tom Hubble, 2006). Virtual Reality 9 A remarkable research being carried out now a day is an attempt to make virtual reality usable by the blind persons in order to enable them to face the real world challenges using modern technology. Although the development of a virtual world can be considered as a great leap in the modern technology, yet a lot needs to be still done in this field. Given below is a chart displaying the possible harmful health effects of virtual reality: (Bing Images, 2010). The progress may be considered as slow mainly because of its complex technology. Other disadvantages include: This technique uses the computer visualization and digital techniques, yet it does not present the true three dimensional natures of objects. Although it is very close to reality, yet is unable to provide the feelings of touch, smell etc. It is still not as beneficial as being really in a field. Visiting a website using virtual reality is difficult and hindered by many factors like the network access, load on network and number of connections etc. Many websites accessed using virtual reality are ephemeral and not permanent. Yet needs much improvement regarding the teaching environment. The user may get lost over different websites, thereby increasing the problem of time management. (Weili Qiu, Tom Hubble, 2006). Some users complain of nausea and vomiting by an excessive and continuous use of virtual reality technology. CAN VIRTUAL WORLD REPLACE THE REAL EXPERIENCE? Virtual world is although quite close to the real world yet it is still unable to replace the feelings of a real world. As an example, the virtual reality technology is now being used for military training as well. But a soldier actually knows that he is not going to get any harm from any bullet coming from an unknown origin or a surprising attack. These feelings can only be experienced while being in an actual war field where all of a soldiers instincts are fully active in order to prevent him from any unknown danger, as he knows that it is real and he can even loose his life if he gets distracted from this actual environment. (Science Clarified, 2010) Similarly, it was found many years back that the pilots trained by using the flight simulators make mistakes while flying the actual plane. This occurs because of the actual differences found between the virtual and the real world. As for example, a flight simulator is unable to present the affects of simulation that a pilot feels during an actual flight. Thus, when he gets into a real flight, he faces confusion while experiencing the new sensation. Yet, this is a temporary problem and is resolved by allowing the pilots trained by flight simulators to fly a plane, only after twenty four hours have passed. These problems are although temporary, but they have raised questions about whether a long term use of virtual reality able to bring about permanent changes, especially in children, whose brains are still under developing stage and can easily be modified as compared to the grown ups. Some psychologists believe that a long term and frequent use of virtual reality is going to change the way, people are used to perceive the real world. According to some psychiatrists, a prolonged use of virtual world can make people avoid real life problems instead of trying to solve them. WORLDWIDE ACCEPTANCE: Although virtual reality technology can be still described to be in its initial stages, yet there are now about 61,000 commercial companies all over the world which are using the virtual reality technology to produce different products. Even at this basic stage, now virtual reality has become a part of the educational training at about 3,600 educational institutes all over the world. (authorSTREAM, 2010) There can be no doubt in saying this that the use of virtual reality has now increased to a great extent than the time when it was introduced initially, all over the world. Given below is a graph showing an increase in the use of virtual reality over the period of years. (Google images, 2010) CONCLUSION: Virtual reality can be described as one of the most important inventions of the modern world. Initially when computer was invented, it did not have much uses. With time, many improvements were made and computer started taking an important place at offices, homes and industries. Development of internet was a remarkable addition and it made the computer a necessity for every work place as well as homes. Likewise virtual reality was developed initially with a very basic knowledge. But now, it has started taking an important place at many work places especially those professions which are related to computer and technology. Still studies are being carried out in order to make further improvements in it, and we can predict its importance in the upcoming time mainly because of the reason that the virtual reality enables a person to visit any place or environment where it is sometimes practically impossible to go in person. One can visit the internal body, the space, the molecular structure s, deep sea, buildings, sky, planets or whatever one can think of. Science is amazing and the computer world is giving the mankind an experience of a totally new world which could not be imagined some decades back. Thus, virtual reality can be easily described as one of those inventions of science, which carry a great elasticity in them and with the research work going on in this field, we can hope to get even better results expected to bring great changes in almost every field using computer technology.

Chemistry uncertainty conical flask Essay

The conical flask was weighted with the balance and the value was recorded. 2) The beaker was filled with distilled water and the water was added into the conical flask up to the 60 mL mark. The dropper was used when water level was approaching the 60 mL mark. 3) The weight of the conical flask containing water was recorded. 4) The mass of water was found by subtracting the weight of conical flask from the weight of conical flask with water. 5) The volume of water was found from the mass of water . 6) Steps 1) to 5) were repeated ten times. 7) 60 mL was subtracted from each of the calculated volume of water. 8) The data obtained from step 7) were compared with each other and the largest value was taken as the absolute uncertainty of the conical flask. -The volume of water poured into the conical flask was being decided while the uncertainty of the conical flask, calculated from the experimental  volume subtracting theoretical volume of water, was being investigated. -The same conical flask and electronic balance was used throughout the experiment to ensure the results were not to be affected by the difference in apparatus used. -The volume readings were taken from the bottom of the meniscus of liquid and it was made sure all the liquid was emptied to ensure accurate reading of volume. – A dropper was used when the water level approached 50 mL mark of the conical flask to prevent solution from overflowing the mark and to ensure accurate reading of volume of solution. -Only distilled water was used in the experiment to access fair results in all rounds of experiments. -The uncertainties of the balance were neglected because the value ( ±0.0001g) was too small and has very little effect on the results. -10 sets of data were taken into account for more accurate results. -The experiment was done in room temperature and in an environment of same wind speed to prevent the experimental results from being affected. -The exterior and the upper 1/3 part of the interior of the conical flask was wiped dry with tissue paper before every set of experiment was carried out to assure accurate measurement of the mass of water contained. -The density of water is assumed to be 1 g/dm ³. The result of the experiment has shown that the uncertainty of a 100mL conical flask is 2mL. Comparing to a 100 mL volumetric flask, which has absolute uncertainty of 0.08mL, a conical flask is rather uncertain and will give inaccurate results. This explains why a conical flask is usually used for holding chemicals (for example in titration, it is used for containing the solution being titrated against and the indicator) instead of used for giving measurements. In this experiment, an observation was that the value displayed on the balance fluctuated within 0.0004 g. This observation was noted as it implied that even though the wind speed was kept constant around the environment (for example fans and air conditioner turned off), the movements generated by man or usage of balance had minor effect on the accuracy of the result. The effect of these small errors on the result can be eliminated by carrying out more rounds of the experiment, or by repeating with different electronic balances. Further investigation could be done on finding the values of uncertainty of different sizes and grades of conical flasks. By repeating the experiment with different sizes and grades of conical flasks, we can gain understanding in different instruments and the result might be used as reference in future experiments involving conical flasks.
