Advanced Audio Coding and Walkman Essay Example for Free

Advanced Audio Coding and Walkman Essay Technology has played an important in part in market and in the society. It has brought positive as well as negative changes. The progression from sheet music to the invention of a phonograph to the walkman, CD player and the iPod has created a modernized society. People tend to move along with these changes creating a market. The idea of transferring digital music to your iPod without purchase of a CD or an audiotape may seem like an extraordinary idea but the idea of digital music has led to the downloading of illegal music. The Walkman may have been the turning point in the music recording industry. It was a chain reaction for later products such as the iPod and the CD player. Long before the iPod made its way into the market making millions; the Walkman was the trendy technology. Sony introduced the Walkman in the 1970s, a new invention that led to be a massive hit. Sony ended up selling around fifty thousand pieces by the end of two months after its release. Eventually, other famous brands such as Toshiba and Panasonic entered the walkman market creating a market in the early 1980s. Surprisingly, the production of the Walkman led to an increase in physical activities. This portable device could be carried anywhere and had a hook to attach to any item of clothing. People started exercising more as one can listen to his or her choice of music while working out especially in gymnasiums. This brought a change in the society as people began to implement physical training more often. This also had a disadvantage since people who had their headphones plugged in tend to be more indifferent to their surroundings. This created an environment, where everyone is tuned in into their little environment being oblivious to what is happening around them. With the creation of walkman, the sale of digital audio tapes also increased. As iPods are the 21st century popular forms of music player technology, the walkman was the latest thing. This generation became more ‘wired’ as teenagers started to grow apart from the notion of young people together singing the songs of the day or the old songs in front of their houses. Sheet music became obsolete, as fewer and fewer people moved to a more modernized technology and era. Comparing to the advances in the 21st century, the walkman is seen as an old portable audio cassette player, where rewinding and forwarding a song would take twenty or thirty seconds. The latest music technology, mp3s or iPod, have put people at an ease with sophisticated technology and its touch screen display has bought a change in this profit-making business. The slick structure and the advanced A Walkman today would cost you merely twenty dollar where as an iPod can cost anywhere from a hundred to a couple hundred dollars. How digital music is illegally downloaded and used today on music players, Walkman on the other hand required the purchase of audiotapes. As Paul Du Gay notes in his book ‘Doing cultural studies: the story of the Sony Walkman’, the walkman accustomed individuals to tune out from the surroundings and caused them to be reclusive. This also led to a cause of a gneration gap between teenagers and their parents or older siblings. The walkman was used by people when in crowded places, such as trains or buses as a means to drown away noises. This seemed as an effective way to creating your own space but this eventually leads to people tuning themselves out even when at home. Teenagers liked to keep their headphones on throughout the day; I believe this led to a distance between them and their peers. Eventually, a type of distance grew among people, sheet music was nearly extinct and the customary ritual of singing together was far disappeared. In conclusion, the Walkman has definitely been a jump from the traditional tape recorder players to portable audio players. Its creation has had its advantages and disadvantages. The increase in the level of physical activity has increased among the owners of Walkman due to the fact that it is portable. Although, on a downside the Walkman has also led to the creation of a secluded attitude.

Patients Rights Essay -- patients’ bill of rights

The practice of medicine in the 1960s saw a change in the doctor-patient relationship that ultimately cultivated the patients’ rights movement. Individuals sought to become proactive in the healthcare and the healing process of their bodies. Because the medical practice was evolving rapidly in technology and specialized care, patients’ healthcare and rights became a major concern that needed to be addressed. In 1973 the American Hospital Association published a patients’ bill of rights that provided the patient with most advantageous healthcare available. This bill of rights required all accredited hospitals to accept this standard moving forward (Patients' Rights, 2004). The American Medical Association (AMA) developed a Code of Medical Ethics which includes: the patient has a right to obtain and discuss health information related to benefits, risks, and costs of treatment alternatives; patient’s can make decisions pertaining to healthcare suggested by the physician; the patient has the right to courtesy, respect, dignity, and attention to healthcare needs in a timely manner; and the patient has a right to confidentially, continuity, and adequate health care. (emedicinehealth, 2011). Communicating openly and honestly between the patient and doctor will allow both parties to make decisions to properly take care of needs. Patients’ have the right to know all details related to the service or treatment that will be provided and the right to refuse any such service or treatment before it happens. This informed consent will communicate exact procedure details, pain intensity and or disability period encountered, risk involvement, and any alternative methods of treatment and its risks.

Nanotechnology :: essays research papers

Nanotechnology is an anticipated manufacturing technology giving thorough, inexpensive control of the structure of matter. The term has sometimes been used to refer to any technique able to work at a submicron scale Molecular manufacturing will enable the construction of giga-ops computers smaller than a cubic micron; cell repair machines; personal manufacturing and recycling appliances; and much more. Nanotechnology Broadly speaking, the central thesis of nanotechnology is that almost any chemically stable structure that can be specified can in fact be built. This possibility was first advanced by Richard Feynman in 1959 when he said: "The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom." (Feynman won the 1965 Nobel prize in physics). This concept is receiving increasing attention in the research community. There have been three international conferences directly on molecular nanotechnology as well as a broad range of conferences on related subjects. Science said "The ability to design and manufacture devices that are only tens or hundreds of atoms across promises rich rewards in electronics, catalysis, and materials. The scientific rewards should be just as great, as researchers approach an ultimate level of control - assembling matter one atom at a time." "Within the decade, Foster or some other scient ist is likely to learn how to piece together atoms and molecules one at a time using the STM ." (Referring to John Foster of IBM Almaden labs, who spelled "IBM" by pushing xenon atoms around with a scanning tunnelling microscope.) Eigler and Schweizer at IBM reported on ".the use of the STM at low temperatures (4K) to position individual xenon atoms on a single- crystal nickel surface with atomic precision. This capacity has allowed us to fabricate rudimentary structures of our own design, atom by atom. The processes we describe are in principle applicable to molecules also". Drexler has proposed the assembler, a device having a submicroscopic robotic arm under computer control. It will be capable of holding and positioning reactive compounds in order to control the precise location at which chemical reactions take place. This general approach should allow the construction of large atomically precise objects by a sequence of precisely controlled chemical rea ctions, building objects molecule by molecule. If designed to do so, assemblers will be able to build copies of themselves, that is, to replicate. Because they will be able to copy themselves, assemblers will be inexpensive.

Kunta Kinte and Gustavus Vassa 2

The essential topic of black people history is the continuous fight to defeat the barrier of race, and the actuality of unequal cultural identity between black and white people. â€Å"This racial bifurcation has created parallel realities or racial universes, in which blacks and whites may interact closely with one another, but perceive social reality in dramatically different ways† (Gordon 2003). Blacks still suffer from discrimination trying to overcome all the difficulties and forget about their terrible past – slavery. However the past can’t die and there are historical masterpieces that remind people about their past experience. Literature is the main sources of them. On the example of the life of two slaves the given paper will prove that the life of   every slave was very much alike, almost the same, because of the lack of any opportunity for slaves to make their life outstanding The life of Kinta Kunte Alex Haley is the author of the novel  «Roots: The Saga of an American Family » Kinta Kunte is the main character of this novel. The movie â€Å"Roots† was created based on the book. This work is considered to be a faction that is a combination of both historical data and creative writing. Some plot is taken from a writing called â€Å"The African† written by Harold Courlander. The main character of  «Roots: The Saga of an American Family »,   Kunta was caught and taken as a slave to Annapolis, Maryland. Soon plantation holder from Spotsylvania County bought him (Gordon 2003). In Maryland a monument to Kunta Kinte was created. It is one of a small number of memorials in the whole world to have the name of a really existed African slave. There are some other monuments like the monument of Zumbi from Palmares Quilombo (a Negro and the leader of revolution) and the monument of Bussa. The memorial of Kunta Kinte represents Alex Haley, manuscript on his knee, narrating his family's history to three kids. In a disreputable event, the Kunta Kinte statue was stolen in a very short period after its putting in place in 1981. It was not found and was restores within several months. But the new one was also stolen. A monument of Alex Haley telling the story to the kids is in its place (Gordon 2003). The author started his narration with Kunte's birth. The main character of the novel was born in the rural community called Juffure in The Gambia in 1750. Kunte was the first of four children of the fighter Oumaru and his wife Binta. As his father was a soldier Kunte's was brought up in very strict conditions and became a good warrior (Gordon 2003). In 1767, when the young fighter went to the wood to create a drum, he was caught by a group of people. Kunte woke up and realized that he became a captive of the white people. Haley shows how they disgrace the young soldier. Kunte and other captives are taken on a steamer for a terrifying three month trip to the United State. (Williams 2001) There were 140 captives of the board of the ship, but only 98 remained alive after the trip. Kunte was among them. When they came to Maryland the young black soldier was sold to a white man who gave him a new name â€Å"Toby† to his shock. For the rest of his life Kunte was dreaming of freedom and making attempts to run away. Once he was caught and the part of his foot was taken out. He married slave women Bell Waller and had a kid by name Kizzy. Unhappily, Kizzy was sold to another plantation. Years later Kizzy got to know that her father died, she came to his grave, crossed the name â€Å"Toby† and wrote her father’s real name Kinta Kunte. (Williams 2001) The rest of the story is about the life of Kizzy and Alex Haley telling about their distress, losses and final victory in America. The life of Gustavus Vassa The character of Kinta Kunte is symbolic; his story tells us the story of many slaves that is usually the same and not interesting and distinguished. The life of the given character is very much alike the life of Olaudah Equiano known as Gustavus Vassa. (Williams 2001) According to his own narration, Olaudah Equiano was born in â€Å"Essaka† not far from the River Niger. His father was a respected man in the village. People in the village were plain, had quiet and happy life. When he was very young he was caught exactly like Kinta Kunte and sold to slavery. He never saw white people before. Equiano had many brothers and a sister, a large happy family. Her sister was caught together with him. Equiano was re-sold several times: he was not demanded because of small height. At last he was taken to Virginia, where he was bought by a man who decided to call his Gustavus Vassa. (Williams 2001) In contrast to Kinta Kunte who has only one nickname â€Å"Toby† Equiano was presented with new names by his owners many times. Notwithstanding that, this time a black man rejected the new one and courageously informed his new possessor that he wanted to be called Jacob. Pascal punished the salve and left him in shackles until he agrees to take the name he thought out for him. Equiano wrote that he had to except the new name at last in order to be freed. The cause of the somewhat strange selection of name for a slave is mysterious. (Williams 2001) In his autobiographical work, Equiano describes the unacceptable treatment of slaves who worked in houses of their owners in Virginia. They went through a number of abnormal types of punishment and traditions like the application of so-called â€Å"iron muzzles† around the mouth of the slave make him quiet which prevented him from normal sleeping and eating. The story expresses the fear and shock Equiano went through in his new surroundings thinking that the eyes on wall were tracing him and a clock could tell his master everything about the mistakes he made in his work.   (Williams 2001) Conclusion The conclusion can be made that the lives of two slaves are very much alike. Both of them were born in small villages, than stolen. That explains their great desire to become free: they were not born slaves, so it was extremely unacceptable for them to appear in such conditions. Both of them lost their real names, suffer almost the same punishments. It is useless to look for the differences comparing the life of two slaves. The age of slavery ended but it has its own consequences. Race as a communal construction makes up its own internal logic and social expressions of pain, irritation, and disaffection within different societies. (Reid-Pharr 1999) Sources Gordon, Dexter B.

American History The Problem of Education in American Culture

American History The Problem of Education in American Culture Education plays an important role in the life of every person. Usually, students’ life may be considerably changed after students enter a college. Students have to choose their professions, think about future life goals, define moral principles, and get experience. Unfortunately, nowadays, students face numerous problems in education: race and sex inequality, school vouchers, private or public education, requirements for distant education, and lack of teachers.Advertising We will write a custom essay sample on American History: The Problem of Education in American Culture specifically for you for only $16.05 $11/page Learn More Each of these issues influences considerably the choice of future education and profession. Students, whose families have low income, usually lag behind, and students, who come from other countries, face language and communication barriers. To solve the problem of education in America, it is necessary to analyze and improve edu cation policies, extirpate the problem of racism, create programs to help students who cannot choose institutions according to their own interests, and find more motivation for teachers. One of the current problems of education in American culture is students’ unwillingness to study. Kids do not want to go to schools/colleges just because of lack motivation and unawareness of education importance. Nowadays, young people have lots of alternatives to education: free-lance jobs, family business, or marriages for money. They just do not want to realize the importance of education and chances they can get. It is necessary to clear up who and how can influence children’s choice, first of all, and then, think over possible ways to inspire children. It is possible to create certain programs, which will introduce the basics of education and underline how the life of every student may be changed after entering an institution. Parents may be provided with the necessary tools in o rder to prepare their children for entering a school/college. â€Å"Students unmotivated to learn are not apt to be as systematic in their learning efforts. The may be inattentive during the lesson and not organized or rehearse material.† (Schunk, Pintrich, and Meece 6) Another issue that deserves attention is the problem of racism in education. It is still unknown why so many discussions concerning race inequality take place in institutions, and no concrete solutions can be presented. The fact whether you are black or white plays a crucial role in the process of choosing school or college. It is high time to solve this problem and analyze what causes the conflicts between students of different races. For example, â€Å"In Midshire University widening participation strategy in colour and culture blind. Initiatives have been mounted to build compact with schools and further education colleges in order to facilitate access.† (Law, Phillips, and Turney 23)Advertising Looking for essay on history?

Why is it so difficult for lots of people to close eyes as for race and nationality? Such questions are needed to be answered with the help of numerous questionnaires and surveys. These investigations should involve either students or teachers, or parents. Maybe, analyzing this question from different perspectives will help to improve educational policies. For lots of students, the choice of school/college creates numerous difficulties. Nowadays, education is not cheap, and not every family may allow their child/children enter any institution they want. Some families have low income that makes entering a college a bit problematic. As a result, talented students are deprived of the opportunity to get the necessary education and become real professionals in a certain field. This is why the idea of school vouchers takes an important place. With the help of school vouchers, families can pick out any school/college for their children according to their own preferences. In the United States, school vouchers’ support is a bit mixed. Not every state supports educational vouchers and presents quite persuasive ideas (financial difficulties, unlimited number of students, etc). Certain subsidy limitations have been adopted, so, most likely, students can get school vouchers if they win some contests or present interesting projects to demonstrate and prove their abilities and skills. Also, it is necessary to admit that the implementation of school vouchers is one more way to motivate students for studying. School voucher programs should be color blind, so that every student has an opportunity to get education in any institution he/she wants. However, not only students are needed to be motivated. Today, lack of teachers creates one more problem in education in the Unit ed States. Nowadays, lots of unskilled teachers are hired in order to provide students with good education. Is it possible that a teacher with lack of experience can study a child in a good way? Hardly! This is why government also needs to think about the conditions, which will be appropriate for both students and teachers, and which will stimulate them. Only a few people agree to work for low salary. Salaries of teachers is changed from $25  000 to $84  000. (Nelson and Drown) Living wages are too high, and people usually change their jobs in order to find something profitable. To my mind, it is high time to remember people that children are our future. Without necessary education, children will not get opportunities to live normal life and earn money, and our future will be under a threat. This is why all people who can teach should remember their predestination and start teaching. In its turn, government should find necessary financial support to provide teachers with good sa laries in order these teachers could study children.Advertising We will write a custom essay sample on American History: The Problem of Education in American Culture specifically for you for only $16.05 $11/page Learn More In spite of the fact that education plays a significant role in the life of every person, students face numerous problems as for choosing an institution and career.

How Human Activities and Processes on the North Yorkshire Moors have affected the Enviroment Essays

How Human Activities and Processes on the North Yorkshire Moors have affected the Enviroment Essays How Human Activities and Processes on the North Yorkshire Moors have affected the Enviroment Essay How Human Activities and Processes on the North Yorkshire Moors have affected the Enviroment Essay In the 1940s and 50s gripping was introduced to the North Yorkshire Moors. Gripping was when Farmers got grants from the goverment to dig miles of trenches (ditches) 50cm deep, to drain wet areas of heath and blanket bog. There were advantages and disadvantages to this though. Gripping would improve the Moors as there would be less water going into the rivers, instead rainfall would go into the grips, therefore the water could be drunk by any lifestock in the fields. Before, when there where no grips it was safer for sheep to graze and play safely but now over the years that the grips have been there,it has caused hazardous for sheep as they could either fall into the watery depths of the grips, or worse farmers lose lambs and sheep, which fall deep into deep, eroded grips and cannot escape. Another Damage that the grips have caused is, Erosion, has caused the ditches to widen over the years it has been eating away at the walls of the grips, the soil has started to break up and fall off. The grips had seemed to be a good thing at the time said one farmer. There was no chance of reversal it would be too expensive. Although the goverment put money towards the grips it would now cost at last twice as much because of the eroded material. In the past many areas of wet moorland were drained with open grips to improve the grazing capacity. Goverment Grants were given for efficient drainage and, while this acheived the prime purpose, it also led to a significant reduction in active blanket bog, which is so important for nature conservation and for providing the insects on which many birds feed. Grouse Chicks, for example, in the critical first few weeks of their life, must have insects. Another disadvantage has been a more rapid drainage of surface water, which can cause erosion of grips and flooding of rivers. Grips are leaking wounds that will never heal said another farmer Hill farmers make a living from all this and think its neccessary for there way of life. But thats not what the villagers think as Lambs have had to be taken away to safe areas in winter as they dont know when the flooding will start. There has been conflict between the villagers and the hill farmers as the hill farmers think they are making the enviroment a safer place when infact they are destroying it. And making it unsafe for there flock. Blocking the grips up would reduce erosion, restore natural drainage patterns, Encourage revegetation of the bog surface. The main priorities would be to block the eroded grips first as they are the main problems,. Methods of Block gripping Dams would stop flooding in other towns so there would be no more hassle. Plant material such as heather would slow down the water flow and would help with the growing of natural vegetation. Before the grips Before the grips were introduced when it rained the rain layed on the surface of the moor until more downpour, the rain then got absorbed into the peat (like sponge) which released the water slowly into the Permeable rock which lets the water through to the impermeable rock which then forces the water out into the rivers. With this proccess there are not many floods to the bottom moors. Using Grips Using grips mean that they act like little rivers which means there is less water going into the rivers but it can also cause flooding downstream because it brings out the river much quicker causing sudden bursts of water which have flooded the towns downstream.The effects of drainage using grips include:Loss of young birds, including Grouse and waders, which fall into and cannot get out of steep sided grips. wet soil conditions and damage to plant species. An increased incidence of flooding and flash flooding caused by greatly increased speed of run off, which also causes damage to Wall and Fences which have been wiped away with the force of the floods.There is a reduced number in invertebrates, which are used as a food source for a variaty of birds. If the insects die then the Fish die and if the fish die then the birds die because they have nothing to eat.
