Actually, MP3 is a part of MPEG characterized by low bandwidth. Millions of music lovers are re-awakened because MP3 gives them an excellent opportunity to store thousands of songs, to search them by genre, artists and title. Thee whole music collection is available when clicking simply one button. Therefore, MP3 is more than a technology. Jones (2000) stated that MP3 is sensational development. Nevertheless, controversies over health risk are present as well as MP3 is stated to entail potential health risk. Jones (2000) cited The Institute of Hearing Research who admitted admitted that â€Å"new technology and ever-increasing storage capacity enables people to listen non-stop for hours and at louder volumes than ever before which could eventually impair hearing†. Thus, MP 3 may cause ringing or buzzing in ears. Andrew Reid, the British Society of Audiology, says (Jones 2000) that â€Å"if people experience that they really need to turn down the player straight away and then consult their doctor if the problems persist†. He comments (Jones 2000) that â€Å"this evidence suggests that people should get better quality headphones if they want to safeguard their hearing† meaning that MP3 may cause users to crank up music to the highest and the most dangerous levels. Prevent Hearing Loss 2006) says: â€Å"If you keep the volume at a level where you can still comfortably carry on a conversation, you won’t need to limit the amount of time you listen to your music†.   Thus, the volume should never be turned all the way up. Actually, the noise is considered safer if a person going next to you doesn’t hear your music and if he hears it means that the music is dangerously loud. So, Spencer (2006) recommended being aware of the music style and noise. To prevent hearing loss doctors strongly recommend giving ears necessary rest not depending on music volume because quieter noise continuing for long period of time is more harmful than highly-intensive noise for a short time period. Summing up, the best preventive strategies are to buy earphones with the highest quality, to limit music volume and time of exposure and, finally, to allow ear to take a rest to recover from noise.

English Journal Essay â€Å"Within the diamond haze of the beach something dark was fumbling along. Ralph saw it first and watched till the intentness of his gaze drew all eyes that way. Then the creature stepped from mirage on to clear sand, and they saw that the darkness was not all shadow but mostly clothing. The creature was a party of boys, marching approximately in step in two parallel lines and dressed in strangely eccentric clothing. (Golding 1954, Ch. 1, p. 19) | This analysis explores the literary feature characterization. In this passage of the novel Golding describes the setting as â€Å"the diamond haze of the beach† to make the reader experience darkness and mystery, as if the reader is actually there. But not just the setting is important in this passage. The author’s choice of words to characterize the choir boys is impeccable. In this quotation the readers see the mysterious â€Å"creature† coming closer and closer to the two boys, Ralph and Piggy. Golding uses imagery to make the reader experience this spooky event. It is evident in the phrase â€Å"Then the creature stepped from mirage on to clear sand, and they saw that the darkness was not all shadow but mostly clothing. † By using the noun â€Å"creature†, Golding instills a scary, horrifying appearance to the group of boys. Also, he uses the word â€Å"mirage† to provide the reader with a mysterious, almost horror-like feeling as the group comes closer and closer. These nouns signify mysteriousness and darkness, providing the readers with a spooky, eerie atmosphere which helps us understand that the group of boys seem dangerous. This passage is taken from the author’s point-of-view and it makes a great impact on the reader. | â€Å"That’s enough! † said Ralph sharply, and snatched back the conch. â€Å"If you didn’t you didn’t. â€Å"-then you come up here an’ pinch my specs-† Jack turned on him. â€Å"You shut up! †(Golding 1954, Ch. 2, p. 46)| This analysis explores the literary feature imagery. In this dialogue of the novel Golding shows an argument between Ralph, the leader, and the other boys. The author uses words and phrases like †You shut up! † and â€Å"That’s enough! † to stress the harshness and seriousness of the situation to the reader. By using â€Å"enough! † the author deeply signifies the disturbance and frustration that Ralph is experiencing as pack leader. Jack is also portrayed as rude and bossy by using the phrase â€Å"You shut up! † This makes the reader feel a scuffle going on between the two, as if two factions are ready to be formed. This short passage shapes the theme â€Å"Inherent evil within humanity† as a whole by giving the reader a rude argument scene to show that there is inherent evil within humanity. | â€Å"Don’t you want to be rescued? All you can talk about is pig, pig, pig! â€Å"But we want meat! † â€Å"And I work all day with nothing but Simon and you come back and don’t even notice the huts! † (Golding 1954, Ch. 3, p. 54) | This analysis explores the literary feature characterization. In this passage of the novel Golding shows Ralph gives a rap on the knuckles to all those who didn’t participate in the hard-working day. By using the words â€Å"don’t even notice†, Golding wants the reader to experience the anger that Ralph has for these children. He states that he â€Å"work all day with nothing but Simon†, which means no child wants to do the hard work, except for those who actually are optimistic and think they have chance to leave this island. The other children’s egoistic behavior becomes problematic for the faction to develop any further. Golding emphasizes the state of stress Ralph is in as the leader of a faction in this sentence: â€Å"And I work all day with nothing but Simon and you come back and don’t even notice the huts! †This passage in the novel is used to let the reader the reader there are lots of egoistic people in the world and that it is very hard to get those people to work. By mentioning the repetition â€Å"pig, pig, pig!†, the children make themselves seem as they only about their personal lives, rather than the life of the faction. | â€Å"Roger and Maurice came out of the forest. They were relieved from duty at the fire and had come down for a swim. Roger led the way straight through the castles, kicking them over, burying the flowers, scattering the chosen stones. Maurice followed, laughing, and added to the destruction. † (Golding 1954, Ch. 4, p. 60)| This analysis explores the literary features setting and characterization. In this passage of novel Golding makes it known that the quietness of the forest is disturbed by using verbs like â€Å"burying†, â€Å"kicking†, â€Å"scattering†. These words add to the destructive mood of the passage. Also, the setting is described as horrendous, menacing, and violent because one of the boys, Maurice in particular, laughs during this passage, meaning his carelessness towards the forest may result in shortage of necessary figures for their faction. Golding makes this scene stick out like a sore thumb because of the complete indiscretion that Roger and Maurice caused to the forest.

Timothy Leary Essay -- essays research papers fc

Timothy Leary "Turn on, tune in, drop out." That saying has turned into the slogan of Timothy Leary’s mind-expanding movement. Although a graduate of both West-Point and Berkley, and a Harvard professor, these were not his greatest lifetime achievements. Throughout his publicized life, he became the spokesperson of the psychedelic age. His devotion to the belief that LSD and marijuana were gateways to enlightenment resulted in a new church, numerous prison sentences, and a following of both celebrities and the general public. When people think of Timothy Leary their immediate response is "Turn on, tune in, drop out," his trademark line, although the meaning of it has often been misinterpreted. Playboy Magazine had thought that his message was advocating, "getting high and dropping out of school," (Marwick 311). When asked by the magazine to explain the meaning of the phrase he responded, " ‘Turn on’ me ans to contact the ancient energies and wisdoms that are built into your nervous system. They provide unspeakable pleasure and revelation. ‘Tune in’ means to harness and communicate these new perspectives in a harmonious dance with the external world. ‘Drop out’ means to detach yourself from the tribal game." (Marwick 312). This was not the first time his methods were questioned. Leary was first publicly noticed, and criticized by then fellow Harvard professors, for his interest in LSD when he and friend, Robert Alpert, wrote an article for the Bulletin of Atomic Scientist. In the article they described a circumstance that in the event of war, the Russians might try to lace the American water supply with LSD. Then, when everybody in America is stoned, the Russians would seize power. They explained that in order to prevent the scenario from happening, everyone should take a dose of LSD so they can get used to the effects (Sterns 278). Although the a rticle shocked the Harvard staff, it didn’t cause him to get fired. Leary was dismissed from Harvard in 1962, only four years after he began teaching there. Leary had experimented with psilocybin, a mind-altering chemical, on his own and the university repeatedly asked him to stop, he refused (Brash 139). Although it angered university 2. authorities, they couldn’t do anything more about the subject since it was a legal substance. While conducti... ...eary was dying of cancer and believed that death should be a happy occasion rather than a sad one. His last words were "Why not?" and after his death his long time friend, John Barlow, wrote, "Timothy Leary died unashamed and having, as usual, a great time. He made good on his promise to ‘give death a better name or die trying.’ " (Marwick 345). Timothy Leary has influenced many people throughout his life by his contribution to society. Whether he advocated the use of drugs or not doesn’t make a difference, although the are what stuck out in people’s minds. The greater message that his life taught was the will of man, and the lengths a person will go to in order to get the point across to the masses. His focus was not money, he gave that up when he lost his job at Harvard, but in his belief that he was right. He truly believed that LSD could enlighten people, and his intentions were to help.

20 Tips for Success in School

Your high school years should be filled with learning and growth. Increasingly, students are finding that high school is also a time of stress and anxiety. It seems that students are feeling more pressure than ever before when it comes to performing well. There are some things you can do to make sure your high school experience is enjoyable and successful. Embrace a Healthy Life Balance Dont stress about your grades so much that you forget to have fun. This is supposed to be an exciting time in your life. On the other hand, dont let too much fun get in the way of your study time. Establish a healthy balance, and dont let yourself go overboard either way. Understand What Time Management Really Means Sometimes, students assume theres some magical trick or shortcut to time management. Time management means being aware and taking action. Be aware of the things that waste time and reduce them. You dont have to stop them, just reduce them. Take action to replace time-wasters with active and responsible study habits. Eliminate Those Time-Wasters Theres a fine line between helpful unwinding between periods of intensive studying and wasting precious hours and attention in ways that are not recharging your batteries. Pay attention to how much time youre spending on social media, on video games, bingeing on shows, or whatever your guilty pleasures might be. Staying connected to friends is vital, but make it quality time that leaves you clear-headed and rested. One helpful tactic is to set aside specific times of day to check your phone and adhering strictly to that schedule when studying. Find Tools That Work for You There are many time management tools and tactics, but youll find that you are more likely to stick with a few. Different people find different methods that work for them. Use a big wall calendar, use color-coded supplies, use a planner, or find your own methods of managing your time. Choose Extracurricular Activities Wisely You may feel pressured to select several extracurricular activities that might look good on a college application. This can cause you to overextend yourself and get swamped in commitments that you dont enjoy. Instead, select clubs and activities that match your passions and your personality. Appreciate the Importance of Sleep We all joke around a lot about the poor sleep habits of teens. But the reality is that you have to find a way to get enough sleep. Lack of sleep leads to poor concentration, and poor concentration leads to bad grades. Youre the one who pays the price if you dont sleep enough. Force yourself to turn off the gadgets and go to bed early enough to get a good nights sleep. Do Things for Yourself Are you the child of a helicopter parent? If so, your parent is not doing you any favors by protecting you from failures. Helicopter parents are those who monitor every bit of a childs life, from waking them in the morning to monitoring homework and test days, to hiring professionals to help with college preparations. Such parents are setting students up for failure in college. Learn to do things for yourself and ask your parents to give you space to succeed or fail on your own. Communicate With Your Teachers You dont have to be best friends with your teacher, but you should ask questions, accept feedback, and give feedback when your teacher asks for it. Teachers appreciate it when they see that students try. Practice Active Study Methods Studies show that you learn more when you study the same material two or three ways with a time delay between study methods. Rewrite your notes, test yourself and your friends, write practice essay answers: Be creative and be active when you study! Give Yourself Plenty of Time to Do Assignments There are so many reasons you should get an early start on assignments. Too many things can go wrong if you procrastinate. You could come down with a bad cold on the night before your due date; you might find out too late that youre missing some needed research or supplies—there are dozens of possibilities. Use Smart Test Prep Studies show that the best way to prepare for a test is to create and use practice tests. For best results, use a study group to create test questions and practice quizzing each other. Eat Well to Feel Better Nutrition makes a world of difference when it comes to brain function. If you feel groggy, tired, or sleepy because of the way you eat, your ability to retain and recall information will be impaired. Improve Reading Habits In order to remember what you read, you will need to practice active reading techniques. Stop every few pages to attempt to summarize what youve read. Mark and research any words that you cant define. Read all critical texts at least twice. Reward Yourself Be sure to find ways to reward yourself for every good result. Make time to watch a marathon of your favorite shows on the weekends, or take time to have fun with friends and let off a little steam. Make Smart College Planning Choices The goal of most high school students is to gain acceptance into a college of choice. One common mistake is to follow the pack and select colleges for the wrong reasons. Big football colleges and Ivy League schools might be great choices for you, but then again, you might be better off at a small private college or a middle-sized state college. Think about how the college you pursue really matches your personality and your goals. Write Down Your Goals Theres no magical power to writing down your goals, except that it helps you identify and prioritize the things you want to accomplish. Turn your ambitions from vague thoughts to specific goals by making a list. Dont Let Friends Bring You Down Are your friends seeking the same goals as you? Are you picking up any bad habits from your friends? You dont have to change your friends because of your ambitions, but you should be aware of the influences that might affect you. Be sure to make choices based on your own ambitions and goals. Dont make choices just to make your friends happy. Choose Your Challenges Wisely You may be tempted to take honors classes or AP courses because theyll make you look good. Be aware that taking too many challenging courses can backfire. Determine your strengths and be selective about them. Excelling in a few challenging courses is much better than performing poorly in several. Take Advantage of Tutoring If you have the opportunity to receive free help, be sure to take advantage. The extra time you take to review lessons, solve problems, and talk over the information from class lectures, will pay off in your report cards. Learn to Accept Criticism It can be disheartening to find lots of red teachers marks and comments on a paper you spent hours crafting. Take the time to read the comments carefully and consider what the teacher has to say. Its sometimes painful to read about your weaknesses and mistakes, but this is the only way to really avoid repeating the same mistakes over and over. Also, notice any patterns when it comes to grammar mistakes or wrong word choices.
