5 Para. Character Sketch On A Seperate Peace Essays - Free Essays 5 Para. Character Sketch On A Seperate Peace Friendship is a bond that is held together by mutual respect and common benevolence. John Knowles explores this realm deeply in his novel, A Separate Peace. Phineas and Gene are best friends, but their friendship is challenged as Gene feels that Finny is superior. Finny, unlike Gene, has no inner conflict, but instead he mentally creates a perfect universe. When Gene finally unleashes his suppressed anger by use of violence, Finny is unable to accept it as intentional in an effort to sustain his perfect world. Unfortunately, he permits this hidden truth to fester until ultimately it destroys his mental paradise along with himself. Finny utilizes his idealistic views of life, genuine caring for others, and charismatic abilities to make people love him in order to preserve his inner utopia. Finnys idealistic views of the real world are optimistic and show the naivet of his character. He has standards of perfection for life, and he is willing to sacrifice the truth to uphold this perfection. This is true even when the truth is openly admitted, such as when Gene confesses that he deliberately jounced the limb so you [Finny] would fall off (Knowles 62). Finny simply denies it and even shows some anger by threatening to kill you [Gene] if you dont shut up (62). This anger becomes the first step in the deterioration of his perfect universe. Finny cannot accept the fact that there are imperfect feelings in the world, such as losing, because Finny never permitted himself to realize that when you won, they lost (27). Furthermore, Finny has a genuine heart, which aids in his friendship with Gene. His sincerity and honesty significantly depicts how uncorrupt his character is. He sets aside certain rules to live by, of which he strongly believes to Never say you are five feet nine when youre five feet eight and a half (26). This reveals how true Finnys character is, and the fact that it is a commandment shows how his morals are the basis for his life. Finny is also very sincere with his friendship towards Gene, by openly revealing that At this teen-age period in life the proper person is your best pal. He hesitated and then added, which is what you are, (40). Whereas Gene is insecure about their friendship, Finny readily admits his true feelings. This genuine attitude deteriorates in the end along with his world as he lies in an effort to suppress the truth. Additionally, Finny has an undeniable charisma that gives him the natural charm respected by all, all but Gene. He has an extraordinary power to make people love him, and it is that love which Gene envies. His power is shown when he was forced to speak himself, the hypnotic power of his voice combined with the singularity of his mind to produce answers, which were often no right but could rarely be branded as wrong (46). His charisma allows him to slip out of difficult situations, such as when Finny wears the Devon School tie as a belt, the substitute Headmaster seemed pleased or amused in some unknown corner of his mind (19). Gene, however, envied this, and it gives him an excuse to unleash his anger and the violence. So consequently, Finnys charisma ultimately leads to his demise. Finny is idealistic in his visions of the world, genuine in his caring for people, and charismatic in his convincing nature, and these qualities make him highly revered by many. Unfortunately, Gene tries to compete with Finny, which is impossible for Gene, so he envies Finny. When Gene releases his anger, Finny is unable to accept the truth, because he wants to preserve his utopia. This perfect world is created by Finnys mind in order to not see the evils of the real world. The friendship between the two of them is not mutual. This is why one must keep their enemies close, but their friends closer, because friends are most likely to stab their friends in the back.

Bioacoustics Monitoring Contributes to an Understanding of Climate Essay

Bioacoustics Monitoring Contributes to an Understanding of Climate Change - Essay Example The high levels of Carbon Dioxide (CO2) yielded from the continuous combustion of fossil fuels is considered one of the major impacts of climate change on ocean acidification. This huge change contributes to diminishing the absorption of sound. Since half of the total percentage of CO2 caused by the consumption is absorbed by oceans, the percentage of acid in the ocean has increased causing the pH level of oceans to drop (Orr et al., 2005). According to the authors, the diminishing of sound absorption has impact on underwater animals’ behavior and will lead to some of these animals adapting new behaviors. However, these adjustments can be harmful to some and beneficial to others. According to the others, the reduction of sound absorption leads to sound travelling longer distances, which can result to a noisy environment for underwater species. This can lead to the extinction of some species which cannot obtain food in the noisy environment. Also, marine animals such as wheels will have to adjust their frequency, take more time and use more sound to communicate with each other. On the other hand, it would be beneficial for wheel to maintain communication with each other in further distance since sound travels faster and further. However, other studies disagree that the increasing in ocean acidification will cause measurable changes in underwater animals’ behaviors, claiming that these studies need to be tested. Unlike oceans, the impact of climate change on freshwater cannot be easily predicated for many reasons. One of these reason is that fishes in freshwater are ectotherms. Hence, the effect of climate change can vary between species. Another reason according to Hobday and Lough is that freshwater systems, unlike oceans, do not follow under the Global Climate Models because of their small sizes. Animals have established ways of

Lake Effect Snow Research Paper Example | Topics and Well Written Essays - 750 words

Lake Effect Snow - Research Paper Example Lake snow effect usually happens during the winter and in particular the Midwest when the area is dominated by cold cP or cA and clear air (Ahrens 207). The specific areas where the lake effect snows are notorious are the eastern and southern shores of the Great Lakes (Geerts 1). When such a phenomenon occurs, the people in this region get prepared for heavy snow showers. These storms are highly localized and they extend only a few kilometers to more a hundred kilometers inland. The snow basically falls as squall or heavy shower in the concentrated zones. The snow is very much centralized such that a part of the city may accumulate several centimeters of the snow, while in another; the ground has nothing (Ahrens 207). Lake effect snow is rampant from the month of November to January. â€Å"During these months, cold air moves over the lakes when they are relatively warm and not quite frozen† (Ahrens 207). The difference between air and water temperature can be as high as 25 degrees centigrade. Studies conducted have indicated the greater the difference in the temperature, the higher the probability of having a snow shower. Causes of Lake effect Snow It is imperative to note that the snowfall is not caused by the proximity of the ocean or the mountains and the difference is not because the eastern and the southern shores are cooler than the regions surroundings; in fact, they are only a little warmer than the surrounding shores.

Langston Hughes Salvation Essay Example for Free

Langston Hughes Salvation Essay In Langston Hughes’ essay â€Å"Salvation,† the author recounts how his failure to â€Å"see† Jesus and be outwardly saved results in a deeper, more stirring revelation: that only he and not Jesus can save his soul. Although Hughes devotes much of his essay to parodying the salvation experiences and apparent hypocrisy of other church members, and he tells us that the church building is stuffy, uncomfortable, hot and boring, he abruptly changes his tone at the end. When he describes how he cried in bed from guilt at having lied about his salvation, the reader realizes that Hughes has indeed undergone a powerful spiritual awakening: he has been saved from his own hypocrisy. Hughes starts off his essay using apparent irony by saying he â€Å"was saved from sin when [he] was going on thirteen. But not really saved. † (Hughes 351). This leads us to believe that he is cynical about Christianity, and we should not believe he is about to undergo any real spiritual transformation. When he describes having attended Auntie Reed’s Baptist church when he was not even thirteen years old, we get the impression that he is not responsible for taking the experience seriously. At that age, children are impressionable and naive about religion, which they may not understand, because it offers protection at a time when they are already protected and forgiven by their parents for errors they make, or â€Å"sinful† acts. Hughes gives the impression that he is being forced to go to church because of social expectations. He is strongly influenced by his friend Westley, who does not hide his real reason for getting baptized, which is to get out of that hot, stuffy church and get on with his adolescence. Westley tells Hughes â€Å"God damn! I’m tired o’ sitting here. Let’s get up and be saved! † Hughes (351). Westley’s ironic and comical interjection aptly sums up Hughes’ view of how the salvation process works in the mind of an adolescent: just do it and get it over with to make your elders happy, because it’s all a game anyway. It is only when Hughes’ aunt Reed comes and sobs at his side and is summoned by the minister that Hughes begins to break down Hughes (351). In paragraph 11, Hughes states: â€Å"Now it was really getting late. I began to be ashamed of myself, holding everything up so long. I began to wonder what God thought about Westley who certainly hadn’t seen Jesus either, but who was now sitting proudly on the platform†¦. So I decided that maybe to save further trouble, I’d better lie, too, and say that Jesus had come, and get up and be saved†¦. So I got up† Hughes (352). Here, Hughes discovers that the mere physical act of rising in response to his summons has begun to change him internally. He may not yet â€Å"see† Jesus, but he certainly sees and feels the effects of what he has done: â€Å"Suddenly the whole room broke into a sea of shouting, as they saw me rise. Waves of rejoicing swept the place. Women leaped in the air. My aunt threw her arms around me. The minister took me by the hand and led me to the platform†¦.. joyous singing filled the room. † Hughes (352). To Hughes, Jesus may as well be in the arms of his beloved aunt as in the â€Å"God damn† of his cocky pal Westley. He finds salvation in the spirit of the moment, and it feels good, if not a little confusing. Towards the end of the story in paragraph 15, Langston begins to notice what he has done wrong and feels emotionally distraught and full of neglect in his actions. He has fooled everyone into believing that he had found Jesus Christ. The only reason why he went up to the podium in the first place was to seek a way out sitting on the pews all day at church being told by the church elders, you’ll be damned if you don’t repent and be baptized! etc. Later on that night, Langston felt not only pressured into doing this but a sense of self actualization that he wanted to truly find Jesus, but in the end he ended up not only hurting himself, but the rest of his family for lying the whole time about his true feelings and the reason why he was in bed crying that whole night. Hughes writes, â€Å"I couldn’t bear the fact that I had lied, that I had deceived everybody in the church, and I hadn’t seen Jesus, and that now I didn’t believe there was a Jesus anymore, since he didn’t come help me,† Hughes (352). This passage provides a vivid explanation of his outlook on those around him and how he betrayed himself into lying for the sake of God. Hughes’ sadness and lack of faith came from those around him who kept on pressuring him to accept Jesus Christ into his heart. In the end, he appears to have turned away from God because he didn’t believe, rather he looked on the outside and not from within being only that he was twelve and naive. However, the fact that he undergoes such a transformation into self-doubt and remorse at having liednot just to himself and to everyone elsebut perhaps also to that notion of God as presented to him in Church. ] What Hughes sees as his own hypocrisy can also be interpreted as his own salvation: not from a traditional baptism of water and spirit and rebirth, but of his own tears of remorse as he realizes he has been baptized into adulthood and the burdens of truth and consequence that are inescapable for Langston Hughes’ Salvation.

The failure to Prevent 9-11 :: essays research papers

Failue to Prevent 9/11   Ã‚  Ã‚  Ã‚  Ã‚  When a giant explosion ripped through Alfred P. Murrah federal building April 19,1995, killing 168 and wounding hundreds, the United States of America jumped to a conclusion we would all learn to regret. The initial response to the devastation was all focused of middle-eastern terrorists. â€Å"The West is under attack,†(Posner 89), reported the USA Today. Every news and television station had the latest expert on the middle east telling the nation that we were victims of jihad, holy war. It only took a few quick days to realize that we were wrong and the problem, the terrorist, was strictly domestic. But it was too late. The damage had been done. Because America jumped to conclusions then, America was later blind to see the impending attack of 9/11. The responsibility, however, is not to be placed on the America people. The public couldn’t stand to hear any talk of terrorism, so in turn the White House irresponsibly took a similar attitude. They con centrated on high public opinion and issues that were relevant to Americans everyday. The government didn’t want to deal with another public blunder like the one in Oklahoma City. A former FBI analyst recalls, â€Å"when I went to headquarters (Washington, D.C.) later that year no one was interested in hearing anything about Arab money connections unless it had something to do with funding domestic groups. We stumbled so badly on pinpointing the Middle East right off the bat on the Murrah bombing. No one wanted to get caught like that again,†(Posner 90). The result saw changes in the counter terrorism efforts; under funding, under manning, poor cooperation between agencies, half-hearted and incompetent agency official appointees and the list goes on. All of these decisions, made at the hands of the faint-hearted, opened the doors wide open, and practically begged for a terrorist attack. So who’s fault is it? The public’s for being 2 96304812 unaware, uninterested, and inadvertently the driving force behind American Democracy? No, of course not, that would be a completely ridiculous idea. In the events of September 11, 2001, the United States Government, by ignoring signs of a terrorist attack and continuous blunders in American intelligence, failed to accomplish one of their basic responsibilities as a governing body: keeping us safe.   Ã‚  Ã‚  Ã‚  Ã‚  September 4, 2001, just a week before the attack on the World Trade Centers. A teletype regarding known facts about a suspected Islamic extremist, Zacarias Moussaoui, was sent to the Central Intelligence Agency (CIA), the Federal Aviation Administration (FAA), the Customs Service, the State Department, the Immigration and Naturalization Services, and the Secret Service.
