Innovations and Inventions for the Hearing Impaired

Innovations and Inventions for the Hearing Impaired No one person invented sign language; it evolved worldwide in a natural fashion, much the way any language evolved. We can name a few people as the innovators of specific signing manuals. Each language (English, French, German, etc) developed their own respective sign languages at different times. American sign language (ASL) is closely related to French sign language. In 1620, the first book on sign language that contained the manual alphabet was published by Juan Pablo de Bonet.In 1755, Abbe Charles Michel de L’Epee of Paris founded the first free school for deaf people, he used a system of gestures, hand signs, and fingerspelling.In 1778, Samuel Heinicke of Leipzig, Germany founded a public school for deaf people, where he taught speech and speechreading.In 1817, Laurent Clerc and Thomas Hopkins Gallaudet founded Americas first school for deaf people, in Hartford, Connecticut.In 1864, Gallaudet College, in Washington, D.C was founded, the only liberal arts college for deaf people in the world. TTY or TDD Telecommunications TDD stands for Telecommunications Device for the Deaf.  It is a method of coupling Tele-Typewriters to telephones. Deaf orthodontist Doctor James C Marsters of Pasadena, California shipped a teletype machine to deaf physicist Robert Weitbrecht in Redwood City, California and requested a way to attach it to the telephone system so that phone communication could take place. The TTY was first developed by Robert Weitbrecht, a deaf physicist. He was also a ham radio operator, familiar with the way hams used teleprinters to communicate over the air. Hearing Aids Hearing aids in their various forms have provided needed amplification of sound for many persons experiencing hearing loss. Since hearing loss is one of the oldest of the known disabilities, attempts to amplify sound go back several centuries. It is unclear who invented the first electric hearing aid, it may have been the Akoulathon, invented in 1898 by Miller Reese Hutchinson and made and sold (1901) by the Akouphone Company of Alabama for $400. A device called the carbon transmitter was needed in both the early telephone and the early electric hearing aid. This transmitter was first commercially available in 1898 and was used to electrically amplify sound. In the 1920s, the carbon transmitter was replaced by the vacuum tube, and later by a transistor. Transistors allowed electric hearing aids to become small and efficient. Cochlear Implants The cochlear implant is a prosthetic replacement for the inner ear or cochlea. The cochlear implant is surgically implanted in the skull behind the ear and electronically stimulates the nerve of hearing with small wires touching the cochlea. External parts of the device include a microphone, a speech processor (for converting sounds into electrical impulses), connecting cables, and a battery. Unlike a hearing aid, which just makes sounds louder, this invention selects information in the speech signal and then produces a pattern of electrical pulses in the patients ear. It is impossible to make sounds completely natural because a limited amount of electrodes are replacing the function of tens of thousands of hair cells in a normally hearing ear. The implant has evolved over the years and many different teams and individual researchers have contributed to its invention and improvement. In 1957, Djourno and Eyries of France, William House of the House Ear Institute in Los Angeles, Blair Simmons of Stanford University, and Robin Michelson of the University of California, San Francisco, all created and implanted single-channel cochlear devices in human volunteers. In the early 1970s, research teams led by William House of the House Ear Institute in Los Angeles; Graeme Clark of the University of Melbourne, Australia; Blair Simmons and Robert White of Stanford University; Donald Eddington of the University of Utah; and Michael Merzenich of the University of California, San Francisco, begin work on developing multi-electrode cochlear implants with 24 channels. In 1977, Adam Kissiah a NASA engineer with no medical background designed a cochlear implant that is widely used today. In 1991, Blake Wilson greatly improved the implants by sending signals to the electrodes sequentially instead of simultaneously - this increased clarity of sound.

Philosophy - Feminism, Moralism, and pornography Essay

Philosophy - Feminism, Moralism, and pornography - Essay Example It is this attitude along with a lack of understanding about human sexuality (admittedly women’s too) that give birth to the new definition of pornography. Had she gained some knowledge about activities like tit torture as depicted in Kama Sutra, she would have thought twice before reaching such a new definition. While stressing on the sadistic attitude of the male-dominated society, it is painful to note the total ignorance the scholar shows towards the element of masochism inherent in women. The scholar is against pornography because of three major reasons. Firstly, it promotes violence against women. Secondly, it provides a totally wrong picture about female sexuality, and thirdly, it promotes male-centeredness (234). It seems that the work goes seriously defective in the fact that it does not give any attention to the impact of explicit sexual content on children. In other words, the scholar is of the opinion that as far as females are not tortured in the portrayal, the material does not have to be considered pornography. Here, she fails to acknowledge the fact that in order to arouse sexual feeling in people including the immature ones, it is not necessary to include bondage or torture. Thus by defining only sexual content with violence as pornography, Longino has provided a totally defective view of pornography. Also, the scholar is alarmed by the fact that pornography has secured its own place in the mainstream media. In the opinion of Longino, this overwhelming acceptance of pornography by the mainstream society and media shows the desire of the male-dominated society to subject females to such activities like rape, bondage, and torture for its own sexual gratification. That means the creation of a society where psychological and physical violence against women is accepted as part of the social culture (234). Admittedly, the scholar is rather unaware about the content of sadism in males as propounded by various thinkers including Freud and

With reference to acid-base balance explore the role of the Essay

With reference to acid-base balance explore the role of the respiratory system in maintaining blood pH - Essay Example The instruction of acid-base equilibrium remains overseen by three critical processes, namely: buffer system, respiratory, and renal methods. The paper investigates the role of the lungs in overseeing stabilization of blood pH. Carbon dioxide (CO2) derives from typical body metabolic processes. Disturbances in the processes impacts on CO2 intensities and HCO3- are expected to produce acid-base disparities (Raymond 2010, p.244). An outstanding system through which the body exploits to direct pH entails the discharge of CO2 from the lungs. The brain adjusts the magnitude of CO2 exhaled by guiding the pace and intensity of breathing. This forces the lungs to either augment or lessen the tempo and intensity of ventilation until the appropriate quantity of carbon dioxide has been re-instituted. The magnitude of CO2 released influences the pH of the blood, which heightens as breathing, turns out to be fast, and profound (Chatterjea and Shinde 2012, p.713). In adjusting, the pace and deepne ss of breathing, the brain plus the lungs direct the blood pH. The Respiratory (Lungs) Buffer Response Usually, blood pH ranges in the region of 7.4 (slightly alkaline). In the event that pH levels drop to 7.6, then body cells are likely to cease functioning. It is obvious that blood pH levels 7.9 are lethal even if they last for a short time, which renders it essential to gain equilibrium in pH levels (Sherwood 2007, p.11). The competence of the body to handle every pH adjustment is steered by three indispensable factors, namely: the lungs, the kidneys, and buffers. In the event that a strong acid manifest, the bicarbonate-carbonic acid, which yields an overall rise of carbonic acid that dissociates into CO2 and H2O. An augmentation of H+ within the blood triggers the medulla to augment the respiratory tempo that assists CO2 eradication (Brown et al. 2011, p.323). In the event that pH stays high relative to an augmentation in HCO3-, the respiratory centre holds back, and consequent ly the respiratory tempo lessens (Raymond 2010, p.245). This enhances CO2 retention in which it becomes accessible to form carbonic acid that cushions the surplus bicarbonate. The respiratory system consequently balances the registered alterations within pH transmitted to metabolic disorders by regulating Pco2 that alters the bicarbonate carbonic acid proportion. Nonetheless, the respiratory system cannot orchestrate any loss or an augmentation of hydrogen ions. Buffers direct molecules that admit or discharge ions in order to maintain the H+ ion absorption at a certain level. Buffers facilitate to saturate up additional H+ ions with the majority buffer entailing a fusion of carbon dioxide and bicarbonate ion (HCO3). CO2 derives carbonic acid (H2CO3) when is liquefies in water and operates as an acid releasing hydrogen ions (H+) when necessitated (Lew 2010, p.31). The respiratory system pursues sustenance of appropriate blood pH, in the event that the bicarbonate/carbonic acid buffe r system fails to react quick enough to stabilize the registered pH interferences, processes such as hyper/hypoventilation can be induced to direct the amount of carbonic acid contained in the blood (Rhoades and Bell 2013, p.454). The respiratory centre reacts by varying levels of H2CO3- within the blood. Hyperventilation makes the body to breathe out and remove CO2 from the bloodstream, through the lungs. The expulsion of carbon dioxide diminishes acidity within the blood pH. The reverse method transpires in cases of hypoventilation that leads to the withholding of CO2 within the blood (Lew 2010, p.32). The CO2 becomes carbonic acid when it dwells within the blood and combines with water. In the event that

The Young Persons Development Children And Young People Essay

The Young Persons Development Children And Young People Essay Parents that are going through a marriage breakdown, divorce and separation can be stressful for all involved particularly the children/young person. They can become emotionally withdrawn and suffer a lack of confidence which can create low self esteem. Due to family upheaval, they may lose focus in their own abilities and suffer mentally. Similarly, children from single parent families may suffer from a lack of a male/female role model which can cause social stigma. Dual parents and lone parents may have to work long hours, leaving little room for direct social, emotional and intellectual support. Becoming part of a new step-family through a parent meeting a new partner can cause friction between children from each side. This could lead the child/young person to become socially and emotionally withdrawn which could increase the risk of bullying by peers. Having numerous siblings can have an impact on children causing additional needs to be met. Children may feel frustrated with lack of attention within the home and also may be required to assist with siblings needs which could cause social and emotional problems. Additionally, becoming a brother/sister to a new sibling for the first time can be stressful and having to adapt to not being an only child can be difficult at first and can create an emotional strain on the child. Being part of a social care system through neglect, physical/emotional abuse and loss of parent can prove difficult for children and although this can largely be a positive experience for many, it can also lead to problems within all areas of development particularly in relation to social and emotional areas. Having a sick parent/carer can be extremely challenging for children, their social and emotional wellbeing can be affected with having to endure possible social stigma and suffer emotionally if not supported in the correct manner. Time off from school may cause intellectual issues and additional help may be required. Family bereavement can be extremely traumatic for children even when a child/young person has been prepared. This can create emotional strain and unexpected outbursts of emotion should be expected. Socially, children may feel different from their peers who havenà ¢Ã¢â€š ¬Ã¢â€ž ¢t experienced bereavement. They may suffer intellectually due to missing school days and also concentration and behaviour may be affected when they are in school. Moving house and/or area can be difficult for children as they have to adjust to a whole new social situation with changing schools and adapting to new routines. Children may become socially introverted and display high levels of emotion. Cultural differences can affect a child/young person through English being spoken as a second language which can cause a lack of confidence at school and additional intellectual support being required. Health There can be many health aspects that affect a child/young personà ¢Ã¢â€š ¬Ã¢â€ž ¢s development. Children become extremely resilient and are often able to manage their conditions very well; however, certain aspects of their development can prove challenging throughout periods of ill health. Children may suffer from conditions such as asthma, which if not well controlled, can cause children to have extended periods of time off from school. This in turn leads to intellectual development being compromised as well as social development due to relationships not being maintained. Disability in children, whether it be physical or intellectual can be particularly difficult. A child that has a hearing impairment may suffer physically through loss of balance or socially through having to communicate in alternative ways such as sign language/makaton. A physical disability such as Cerebral Palsy can be physically challenging due to being restricted in taking part in certain activities. This can affect social situations due to these restrictions and can affect a child/young person emotionally questioning why they are different causing low self-esteem. Being diagnosed with a serious illness such as cancer as a child/young person can also prove to lead to developmental issues. All areas of development can be compromised, intellectually, through missing school and being too ill to complete set work. They may suffer physically depending on the specific illness causing them to be weak and/or in too much pain and discomfort to complete physical activities. Socially they may be too ill to interact with others and/or maintain friendships. They may also become emotionally withdrawn and find it difficult to cope with their emotions. Allergies affect many children, particularly food allergies; this in turn can lead to social problems as they may become excluded from certain situations where their allergies are not known. In contrast they may feel a certain social stigma as their allergies are highlighted, for example; when eating lunch at school, they may be required to wear a special badge which shows their allergies, causing them to feel different from their peers. They have to be more physically aware of their condition and how this can cause changes in their body and manage this accordingly. Environment Environmental factors can play a huge part in affecting a child/young personà ¢Ã¢â€š ¬Ã¢â€ž ¢s development. These can vary from cultural factors to living conditions. Children/young people from less advantaged backgrounds who live in poverty can have their development seriously compromised. They are less likely to have educational support from parents/carers which in turn creates intellectual problems for the child/young person. This is further influenced by having a lack of learning resources available such as access to computers and books. They may become disillusioned with education from an early age which sets them on a path of social and emotional turmoil. Also, they may suffer socially by not being able to participate in certain paid activities offered through school and outside school which means they interact less in physical activities. They may also feel that they cannot compete with their peers with regards to fashion trends and owning the latest technology. They might not seem to be as physically strong as their peers; parents/carers might experience difficulty in providing healthy, regular meals which can cause problems with their phy sical well-being. Their emotions can seem quite immature at times and they may well become emotionally withdrawn but also prone to emotional outbursts associated with behavioural difficulties, displaying a lack of attention.

The Debate Of Raising Minimum Wage - 1910 Words

Debate of Raising Minimum Wage Raising minimum wage has been an ongoing issue for many years. Similar to every debatable issue, pros and cons are inevitable. In the United States, minimum wage started when the Fair Labor Standards Act of 1938 (FLSA) was passed and minimum wage started at 25 cents per hour. The purpose of setting a minimum wage is to set a maximum workweek and to eliminate child labor. It is defined to be the least amount of money employers are obligated to pay their employees by law. As the years passed, the minimum wage began to increase to accommodate the growing economy. Although the wage has increased from a mere 25 cents per hour to $7.25 over the course of 75 years, living expenses are much higher causing many people to be poverty stricken (Debate.org). President Obama proposes raising the minimum wage, so that it would help minimize the income gap in America. However, most business organizations and the Republicans oppose to the idea, saying that it could potentially lead to more economic p roblems. While both sides have valid points, which one provides a more compelling argument? In the United States, the minimum wage should be raised in every state; therefore workers can have a more comfortable standard of living, lower the poverty line, and minimize the income gap. The increase of minimum wage could lead to a better quality of life. Many had lived barely paying for the minimal necessities such as shelter, food, water, clothes, etc. The topic ofShow MoreRelatedEssay on The Debate over Raising the Minimum Wage1502 Words   |  7 PagesThe federal minimum wage was raised to $7.25 an hour by Congress in 2009, something that has been carried out only a handful of times since the establishment of the wage in the Fair Labor Standards Act in 1938.

The Philosophical Approaches of Kants Deontology and...

In the 1997 film Extreme Measures a young British doctor, Guy Luthan, who is serving a residency in a New York hospital, is faced with some difficult moral and professional dilemmas. This film used Dr. Luthans dilemmas, which dealt with these sensitive issues of doing what is right regardless of the consequences involved, as well as questions involving scientific advancement and experimentation. How far can medicine go in the name of progress or helping humanity? Dr. Luthan discovers that homeless people were being used as guinea pigs in experimental research for the good of humanity. Using the philosophical approaches of Kants Deontology and Mills Utilitarianism, I will present the ethical parameters of Dr. Luthans dilemmas and how†¦show more content†¦He believes that we should never treat a rational being as merely a means to an end, but respect for all individuals; that they are unique and should be respected as a person, never to be sold out to the happiness of the majority. Rosenstand states Kant human beings and their bodies are not commodities to be used for someone elses purpose, even if that purpose may be the greater good and if the way to produce the most utility is to perform an act that violates the rights of a few, than it is morally right to perform that act, but shouldnt individuals rights be respected even if violating them would do more good for society as a whole? The homeless people did not volunteer for these experiments and were killed. Their rights were not respected, even though this research may ultimately provide a cure for spin al cord regeneration. Although I realize, especially being a nurse, that this is currently a much-heated ongoing debate in the medical field and I feel this is an area of much disregard for peoples rights. Kants deontological moral theory also claims that the right action in any given situation is determined by the categorical imperative, which provides a formulation by which we can apply our human reason to determine the right and rational thing to do, which is our duty to do it. This imperative applies to all rational beings independent of their desires and that reason tells us to follow no matter what. By his categorical imperative we
