Hearing Loss from Mobile Phone Use

Hearing Loss from Mobile Phone Use Discussion Mobile phones have become a part of modern life style. There has been rapid boom in the number of mobile phones in the recent decade. This rapid worldwide expansion of mobile telephones raises questions regarding possible effects of the emitted radiofrequencies on the health of the consumers. The electromagnetic waves can affect the human health ranging from increase the blood pressure, cause memory loss and induce migraines, hearing impairment to even cancer can also occur. Of all the anatomical structures, the ear is in the closest proximity to the mobile phones, hence most potential organ system to be damaged by the electromagnetic waves emitted from the mobile phones. Pure tone audiometry is a key hearing test for assessment of hearing threshold of the individual. It determines the degree of hearing loss and also type and configuration of hearing loss. Pure tone audiometry uses both air and bone conduction audiometry, the type of loss can be identified by the air-bone gap. In our study, while comparing the results of pure tone audiometry in controls (n=60) and total cases (n=60), it was found that in control group 51 individuals had normal hearing threshold, 08 had mild hearing loss and 01 had moderate hearing loss. Of the total cases, 39 had normal hearing threshold, 19 had mild hearing loss and 2 had moderate hearing loss. No individual in the cases or control group had severe or profound hearing loss. Chi square test with yates correction was applied for statistical analysis of the data, and difference was found to be significant (p value0.05). While comparing the results of distorted product otoacoustic emission (DPOAE) in controls (n=60) and cases Group A (n=30), it was found that in cases group A, 19 individuals passed the test and 11 individuals failed the DPOAE test. Chi square test was applied for statistical analysis of the data, and results were not found to be significant (p value>0.05). On comparing the results of distorted product otoacoustic emission (DPOAE) in controls (n=60) and cases Group B (n=30), it was found that in cases group B, 15 individuals passed the test and 15 individuals failed the DPOAE test. Chi square test was applied for statistical analysis of the data, and results were not found to be significant (p value>0.05). The European project EMFnEAR, was done to assess the harmful effects of short term electromagnetic waves emitted from UTMS mobile device over the outer hair cells. Functioning of outer hair cells was assessed by DPOAE. They concluded that short term exposure to EMFs of mobile phones does not cause measurable immediate effects on the human auditory system. Renzo R et al also conducted a similar study to assess the short term effects of mobile phone use on ear, assessed by transient evoked otoacoustic emissions and brainstem evoked audiometry response. The study parameters were similar to our study but they studied the short term effects of EMFs in contrast to our study where we tried to find the effects of long term exposure. They did not find any change in the auditory functions, before and after the short exposure to electromagnetic radiations. Ozturan et al assessed transient evoked OAE and distorted product OAE in adults exposed to 10 min telephone call using GSM mobile phones. The tests were done before and after the exposure. They concluded that otoacoustic emissions did not change after the electromagnetic waves exposure. Bamiou DE et al also reported that there was no change in the transient evoked otoacoustic emission, due to electromagnetic waves of mobile phones. S Bhagat et al, studied the effects of chronic exposure to EMF emitted from mobile phone on inner ear by using distorted product otoacoustic emissions. Individuals using mobile phones for more than 4 years were studied. It was concluded that long-term and frequent exposure to EMFs from mobile phone does not cause damage to outer hair cells of cochlea. P. Karthikeyan et al did a study on hundred students who were mobile phone users. They were divided into two groups of more than and less than two hours of mobile usage. DPAOE was done and compared to controls. Significant change in DPOAE was seen in cases, more so in group with more than two hours of cell phone usage. Alsanosi AA et al did a study to assess the immediate consequences of 60 minutes exposure to mobile phones on hearing function by determining changes in distortion product otoacoustic emission (DPOAE) and hearing threshold levels (HTLs). They concluded that sixty minutes of close exposure to electromagnetic fields emitted by a mobile phone had an immediate effect on HTL assessed by pure-tone audiogram and inner ear (assessed by DPOAE) in young human subjects. While in our study, on comparing DPOAE, we did not find any significant difference between the total cases and controls. On comparing the each sub group of cases to controls, no statistically significant difference was noted. This is in concurrence with most of the studies done in India and abroad. Though, P. Karthikeyan and Alsanosi have shown different results from those observed in our study. Though a lot of research publications are available in favour of and against the results observed in our study, but in all these studies studied the effects of electromagnetic frequencies of mobile phones on functioning of outer hair cells, but no criteria was taken as standard for comparison as different duration (in years) of exposure, different hours per day of use, and acute effect v/s chronic effects. The major limitation of epidemiological studies addressing the health effects of mobile phone use is related to exposure assessment. Also, other factors were not taken in account like exposure to noise, which is known to cause damage to outer hair cells much before any change in pure tone audiometry is seen (Anjali Desai et al, 1999) (RJ Salvi ea at, 2000). So, with all these factors nothing can be said with much certainty. Further research is needed to establish the effect of EMF on outer hair cells. The present scientific evidences are insufficient to support the belief that there will be no ill effects on human health and the present safety standards are enough to protect users from ill effects, if any. This present situation of scientific uncertainty calls for the requirement of both precautionary measures and further research. Ill effects of mobile phone use on health might be of the field of interest for future research. We conclude from our study that: mobile telephones should be used for short periods only, only for essential purposes, and unnecessary long conversation over mobile phones should be avoided.

Ethics †Utilitarianism Essay

Utilitarianism is an ethical theory that assesses an action as morally right and just if it produces the most amount of net happiness. There are two forms of utilitarianism: act utilitarianism and rule utilitarianism. Act utilitarianism is the standard form, which considers all paths of the action that lead to immediate and long-term happiness, as well has the magnitude and how long the happiness will last. Furthermore, if all paths lead to the same amount of net happiness, each path would be just as morally right as the other. It also does not take into account the number of people it affects – it only considers the amount of happiness. To English philosopher Jeremy Bentham, the founder of utilitarianism, happiness is pleasure and the absence of pain. He believed that all types of pleasure, if the in same amount, were also equal in quality. However, it is difficult to calculate an amount of happiness. Is the amount of happiness one receives from getting a promotion at McDonald’s the same as happiness one gets from graduating law school? So, John Stuart Mill, fellow philosopher and follower of Bentham’s utilitarian theory, believed that different pleasures have different values. To Mill, physical pleasures are valued less than pleasure that invigorate the mind. Thus, in the McDonald’s promotion and law school degree scenarios, Bentham would argue that they would each render the same amount of happiness, whereas Mill would argue that receiving a degree from law school would render more happiness because it would bring out more possibilities for a career and ultimately increase one’s well-being. In addition to bringing out the most happiness, the utilitarian theory also recognizes that all the possibilities of an action may not bring any net happiness. In these instances, the theory guides one to choose the action that would produce the least amount of unhappiness. There are two major criticisms utilitarian’s face. One is that no one can possibly know all immediate and future ramifications of an action and even if it were possible, it would take too much time in real-life scenarios to practice. A utilitarian would agree that no one can possibly know all consequences of a given situation while defending that the theory is used a guide to maximize happiness. A utilitarian would also note that since people generally know what happiness and one’s well-being consist of, it helps eliminate obvious wrong choices to save time. The second major criticism is that the action itself, though yielding the most happiness, may not be morally right. In these instances, a utilitarian would argue that this flexibility is realistic and can be applied a real-life situation that are not always black and white. In real-life there are often grey areas where one may need to make difficult or seemingly immoral decision, but the end result of the action may bring about the most happiness than an action that was moral. The second form of utilitarianism, rule utilitarianism, is similar to the standard form except that it adapts a set of guidelines, an â€Å"optimal moral code† to determine right or wrong. It is also emphasized in rule utilitarianism that if an action produces the most amount of happiness, yet defies the optimal moral code, it is wrong. Challenger Disaster. In January 1986, space shuttle Challenger exploded because the O-rings failed to seal in the booster rocket joints due to low temperatures the day of the launch. Morton Thiokol, Inc. was the manufacturer of the booster rockets and one of Thiokol’s engineers, Roger Boisjoly, found that low temperatures detrimentally affected the seals of the booster rockets. He informed his superiors of his findings, but they were deemed as insignificant. The night before the flight, Boisjoly and his colleagues advised against the launch due to the low temperatures, but their employers ignored the advice and moved forward with the liftoff. All seven astronauts onboard died in the explosion. In accordance with the utilitarian theory, Boisjoly did act morally right. He informed his superiors and NASA of his research findings to avoid failure and reduce the amount of unhappiness – the death of the astronauts. Thiokol and NASA, however, did not act morally right. Though the postponing of the launch was not favorable, it would to allow more time to redesign the seals and most likely avoid the catastrophe. They also could have postponed the launch to a day with optimum temperatures for the seals. Consenting to Sexual Harassment In Vinson v. Taylor, Mechelle Vinson claims that her supervisor Sidney Taylor sexually harassed her. She testified that after a year of working at the bank Taylor made advances on her saying that she â€Å"owed† him for getting her the job. She turned him down initially, but eventually became sexually involved with him for her last three years she was employed at the bank. She claims that Taylor raped her and if she did not submit, she would be terminated. Taylor denied the accusations saying that he has never had any sexual relations with Vinson and that Vinson made advances on him. And in retribution for denying her, she filed charges against him. The courts ruled that the relationship between Vinson and Taylor was voluntary and that the employer was not liable, especially since Vinson to not notify the company. Vinson appealed the case and the Supreme Court then ruled that the advances on Vinson were unwelcomed though voluntary. They did not disclose whether or not the employer was liable for sexual harassment. The rule utilitarian theory applies here in that Courts followed a set of rules to produce an outcome. It’s also a case of what action renders the least amount of unhappiness. Through Vinson’s appeal the court stated that regardless of her willingness to have sexual intercourse with her superior, it was unwelcome. It’s difficult to say what the outcome is since the Court did not state whether or not the employer was liable. Parable of Sadhu In the parable of sadhu, Bowen McCoy makes a 60-day trek with his friend Stephen, a few porters and Sherpas in the Himalayan Mountains. They reach a point of the trip where they must make it over an 18,000 foot pass over a crest to reach Muklinath, an ancient holy village for pilgrims. The take a night’s rest before they make the pass and there are a few groups the are within range; a group of New Zealanders, two Swiss couples and a Japanese hiking club. The next day, the New Zealanders depart for the pass first. Stephen, who is beginning to suffer from altitude sickness, and Bowen begin their journey to the pass when they see one of the New Zealanders carrying an almost naked, barefooted sadhu across his shoulders. The New Zealander leaves him with them exclaiming that he has done what he can and that they should care for him because they have porters and Sherpa guides and that he and his group are moving forward with their trek. Bowen checks his pulse to find that the pilgrim is alive. They wonder why he has hardly any clothes on and why he did not choose the safer route. Stephen and the Swiss couples begin to take off some of their clothing to warm up the sadhu. Bowen does not hesitate to move forward as he wants to make it over the pass and the journey becomes more dangerous as time passes; the ice steps would melt and would make the path slippery. Bowen continues, leaving Stephen, the Swiss, and the Japanese behind. The Swiss catch up to Bowen finds out from them that the sadhu was doing fine and that Stephen is approaching. Stephen is upset with Bowen and asks how he feels about contributing to the sadhu’s death. Stephen tells Bowen that he stayed with the sadhu until the Japanese arrived. He asked the Japanese to borrow their horse to take the sadhu down to the hut, but they refuse and give him food and drink before continuing on. Stephen then asked the lead Sherpa, Pasang, to get a group of porters to carry the sadhu down, but he also refuses because he believed it would exert the porters’ energy and that they would not able to do it before the ice melted into a slippery slope. Pasang encouraged Stephen to continue with the time-sensitive hike and the Sherpas carried the sadhu down to a rock in the sun and pointed out to the hut that was 500 feet away. The last time the Sherpas saw the sadhu, he was throwing rocks at the Japanese’s dog, which had scared him. Though it may seem morally wrong to leave the sadhu and carry on with the journey, Bowman acted correctly according to the utilitarian theory. If he had helped the sadhu get across the pass to Muklinath, where he seemingly came from, Bowman may not have had the energy to do so and risk both of their lives, which would be the most amount of unhappiness. If he backtracked and took the sadhu to a hut for warmth and safety, he would have jeopardized his trip and defeated the purpose of this journey and moreover, the pilgrim may not have wanted to be â€Å"saved† for he was nearly naked and did not chose the safer route. One Nation Under Wal-Mart Wal-Mart is the largest company in retail with nearly 5,000 stores and 140 million shoppers. It continues to grow as they open more and more stores that sell household items at bargain prices. As they expand, they are able to offer lower prices because they can buy in very large bulk quantities and demand better prices from their vendors. Though it seems that everyone would be in favor of this large bargain retailer, who sells consumer necessities at extreme low prices, there are many critics of Wal-Mart’s operation. They stomp out small, local â€Å"mom and pop† shop business and compete with supermarkets, eliminating jobs and disrupting communities. They are also an anti-union establishment, pay low wages and most of their employees do not receive health insurance. Lastly, they are criticized for not carrying certain products like racy magazines such as Glamour or Cosmopolitan. Thus, locals often refuse and dispute the expansion of Walmart in their town. According to the utilitarian theory, Wal-mart is not behaving morally wrong. They are abiding by the laws. Though they may pay low wages and not offer health benefits to part-time employees, they are able to employ 1. 4 million people. Their business also allows consumers to purchase necessities at some of the lowest prices available. Furthermore, the decision to not carry certain products like racy magazine or music with explicit lyrics would outweigh the fact that they carry thousands of household necessities at a bargain. Face Transplant: â€Å"Highly Risky Experimentation† Isabelle Denoire was victim of a terrible incident that left her face, extremely disfigured. Her lips chin, nose were clawed and bitten off by her dog. The events that led up the incident are uncertain. She said that she took meds to help her sleep and that while walking down her hallway on the sleeping medication she stumbled over her aggressive dog that she had just adopted. Her daughter said that Isabelle tried to kill herself and the dog was trying to wake her up after she fell to the ground and lost consciousness. While in the hospital the chairman of the department of Maxillofacial Surgery at Amiens University Hospital, Dr. Bernard Devauchelle thought that she should would be a good candidate for an experimental face transplant that was considered time sensitive because the longer they would of waited the more scar tissue she would have had, which would of made the surgery more dangerous. With consent from Isabelle they partial transplant was done but a wave of criticism came once the news was released. Many in the industry felt that the surgery was too dangerous and other option should have been considered. They thought that Dr. Devauchelle insisted on doing the surgery not because he wanted to do what was best for the client but so that he would get publicity for it. They also believed that he chose the wrong sort of client for such an operation. Since Isabelle had tried to commit suicide she wouldn’t be a good candidate because she might not be able to deal with the cameras and news attention, that it might be more than she can bare and wasn’t mentally strong enough to handle it. According to utilitarianism, an action is right if it brings about as much net happiness as any other action the agent could have performed. I believe that Dr. Bernard Devauchelle did take into account other possibilities before they made their decision to do the partial facial implant. It was a time-sensitive decision his patient needed to make and according to him, she eagerly wanted him to help her so that she could be as normal as possible again. Critics of the transplant dispute that was he did was morally wrong, but ultimately it was Isabelle’s decision. I have learned that all real-life decisions are not just black and white. Some are easy and some difficult and even harder. We all have general innate moral code of conduct and the rule utilitarian theory is one that I relate with the most.

The Shooting of Michael Brown Essay

Michael Brown was an 18 year old black man who was shot and killed by police officer Darren Wilson in Ferguson, Missouri 08/9/2014. Michael had intensions to go to college with no previous criminal record. The death of Brown sparked subsequent events in Ferguson and became a national controversy touching on much larger national issues of race, justice, and police violence. This event grew even more national attention when police reacted to protesters, even those acting peacefully, with military-grade equipment such as armored vehicles, tear gas, rubber bullets, and sound cannons. Ties between local residents and their government arose again when heard the investigation into the shooting, inherently secretive grand jury proceedings and subsequent reactions which controlled by mostly whit politicians despite Ferguson’s majority black population. One of the main reasons this shooting grew national attention was the fear commonly held by many parents is that black lives matter les s, particularly in the face of increasingly heavily armed police who carry tremendous legal freedom. Allegedly, Wilson claimed that Brown was charging at him and he fired 6 gunshots at the unarmed man. Brown died 150 ft. from the car, despite earlier statements that Brown died just 35 ft. from the vehicle. Two of the six shots were fired at the head of the unarmed man. Eyewitnesses who went public said Brown and Wilson had a confrontation at the officer’s SUV. Brown ran and Wilson chased after Brown and shot the teenager to death as he attempted to surrender. Constitutionally, police officers are allowed to shoot to protect their life or the life of another innocent party, and/or to prevent a suspect from escaping but only if the officer has probable cause to think the suspect’s committed a serious violent felony. Officers must demonstrate that their actions were objectively reasonable given the circumstances and compared to what other police officers might do (According to David Klinger, University of Missouri-St. Louis Professor). Wilson needed to demonstrate that he feared for his life not just when Brown was by the car, but even after he started shooting, he needed to establish that Brown continued to pose a threat to him until the last fired shot. Brown’s family urged a Michael Brown law following Grand Jury’s Decision not to indict Officer Wilson. NAACP, National Action Network, and others have been working with the family to create a law where it requires that every police  officer in every American city is required to have video body cameras that record every move they make. The benefits of officers wearing body-worn video technology include evidence that both officers and civilians acted in a more positive manner when they were aware that a camera was present, new opportunities for effective training of law enforcement officers presented by the use of cameras, and useful evidence of interactions was often captured on video (as reported on the white house petitions gov page). This would be a Consequentialism solution where the consequences of one’s conduct are the ultimate basis for any judgment about the rightness or wrongness of that conduct. Hopefully, this Law will clear up the major hurdles the black community continue to face in the United States 21st Century.

Galileos View of the New World Essay - 1339 Words

Galileo’s letter to the Grand Duchess Christina caused much controversy when it was written in 1613. It caused such controversy because it was an indirect attack on the Catholic Church with a viewpoint that was not of the ‘status quo’. This essay will thoroughly analyse this document. It will analyse the context behind what was happening in 17th century with regards to science and religion. Secondly it will critically explain and analyse the grounds behind why this document actually holds significance.

In order to understand and analyse this source, the letter needs to be in its 17th century context. During this period, the Catholic†¦show more content†¦He argues that Galileo liked to create controversy . This could set a precedent that Galileo wanted to cause uproar by going so far to the extreme that the nobles and the Church would take a serious look into his findings, when he may have exaggerated certain points. One of Galileo’s main issues was the purpose of scripture with regards to interpretation. Galileo makes the argument that Scripture cannot be wrong but it is up to the interpretation of it. For example, he stated, â€Å"Though the scripture cannot err, nevertheless some of its interpreters and expositors can sometimes err in various ways† . Furthermore he states that if we were to take the literal meaning of what the scripture states – we would be personifying God by giving him human characteristics of a body and emotions. In essence the literal interpretation would give God the right to make mistakes, which of course would not be accepted by anyone in the church. Galileo did have a basis for his argument on the relation of the interpretation of scripture with regards to science. Copernicus, in his letter to Pope Paul III, stated that there are many differing interpretations within the scientists focused on astronomy. One of the main points he makes is that astronomers cannot agree on how to accurately measure the tropical year .
