The Indian Removal Act/Trail of Tears Tristan Bennett Central High School November 9, 2015 3rd Period Abstract On May 28, 1830 Andrew Jackson, the president at the time, signed the Indian Removal Act making it a law. The law gave the U.S. government the right to exchange land west of the Mississippi for Indian Territory in the state borders. Some tribes relocated peacefully, but most resisted the relocation. The United States government forced Cherokee Indians to move and 4,000 of them died being relocated giving the forced movement the name ââ¬Å"Trail of Tears.â⬠The Indian Removal Act/Trail of Tears In the early nineteenth century, the United States wanted position in the West, power was still in the hands of Native peoples. The Native Americans outnumbered whites and controlled the resources and routes of movement. Native Americans were not only fighting with the U.S. but with other Indian nations. Natives started to become even more unsettled as the U.S. government removed most eastern Native groups beyond the Mississippi River. The Indians were viewed as standing in the way of the progress of the new nation by the settlers and many other people who were trying to settle the U.S. The settlers who were eager to have land for more cotton pressured the government to gain Indian Territory.

Evaluating Areas of Knowledge Free Essays
Music can affect us in many ways. It can evoke emotion or bring back a long-forgotten memory. It is present in nearly every aspect of life. We will write a custom essay sample on Evaluating Areas of Knowledge or any similar topic only for you Order Now Anywhere you travel, you come into contact with music. Whether it is on the radio in the car, in the supermarket, or on television, there is no escaping the constant presence of music. Music is composed for various reasons and purposes. Sometimes, composers are compelled to create a musical work to express their emotions, or even opinions. Music is also created to express the cultural aspects. Since there are so many reasons music is created and purposes it is used for, how is it possible to know music and in what ways can music be known? According to the International Baccalaureate Theory of Knowledge, there are several specific ways of knowing that allow knowledge claims to be evaluated. The infinitive, to know, can be evaluated by using reason, language, perception, and emotion. All of these ways can be utilized when evaluating the claim ââ¬Å"I know this music. â⬠Also, most of these mentioned ways of knowing can be applied to other areas of knowledge besides the arts. To begin, knowing music can be evaluated by using reason as logic. Obviously, if someone where to make this claim, he could simply be referring to the fact that he had heard it before. But logically, looking on a deeper level, the claim could mean that he had played through the music before. Often when musicians play a piece of music, or especially when it is performed, it has greater meaning to them and allows them to know it more intimately. When playing a piece of music, artists can put their own personal feeling into it. They can vary certain aspects such as tempo and phrasing. Not only does playing music speak to a listening audience, it speaks to the artist. This makes playing music a very psychological process, as it evokes certain feelings from listener and performer. Very gifted musicians are sometimes able to merely look at a piece of music, to analyze each note and rhythm, and be able to claim they know the piece. Wolfgang Amadeus Mozart was able to know music in this way. He would compose entire symphonies and concertos entirely in his mind before ever writing them down. And when he did write them down, he never changed a note. Mozart never had to physically hear a piece of music to know what it sounded like; he could hear it in his mind. Likewise, this was true for Beethoven, who composed and conducted his ninth symphony after becoming deaf. This process of knowing occurs on a much more intellectual level then actually playing music. However, both methods present knowledge of music. Besides using reason as logic, one can also consider the reason in the purpose of music in order to fully know it. Music is usually always created for some purpose. Composers are inspired and feel compelled to express their creativity. However, despite the composerââ¬â¢s initial purpose for the music, its purpose to society may become completely different. For instance, many early classical composers were hired by courts and forced to compose music for the king. Often they would just write so as to get paid and to save themselves from poverty or execution. They would never have imagined that their music would, hundreds of years later, be listened to in the homes of middle class amilies as their children fervently practice the current assignment from the piano teacher. Music can be written to express opinions of society, culture, and authority. The popular rapper Eminem, constantly criticized for his outspokenness, articulates his views through his controversial lyrics. Similarly, the members of the heavy metal band Rage Against the Machine are known for their radical views of government and ha ve even been arrested several times for protesting on the steps of the capital. Rage uses their music to communicate their opinions and speak to others who feel the same. Altogether, the purpose of music can be used to evaluate how it is known. Next, the claim can also be evaluated by analyzing certain aspects of language. Semantics is a term often applied to the study of meaning in language. In order to study language, one needs to consider two aspects of language: denotation and connotation. Denotation can be thought of as the way in which a word is defined, as in the dictionary. Connotation, on the other hand, is thought of as the color of the word, or what it implies. Therefore, according to the Merriam-Webster Online Dictionary, the definition of the verb ââ¬Ëto knowââ¬â¢ is: to perceive directly, or have direct cognition of, to have understanding of, to recognize the nature of, to recognize as being the same as something previously known, to be acquainted or familiar with, or to have experience of. The denotation of a word is very straightforward and differs from the connotation in that it lacks emotion. For example, when trying to explain love to a child, it does no good to give them a dictionary definition. On the other hand, the connotation of knowing can be explained in countless ways. For example, the word can infer that there is a strong emotional connection, whether it be positive or negative. The connotation also involves many other areas other than just the word, such as the tone of voice it is said in, or the context in which it is placed. When evaluating a claim, one cannot fully depend on a single aspect of semantics. Both denotation and connotation need to be taken into account in order to evaluate knowledge claims. In addition, perception is another way of knowing. Perception varies between all individuals. Perception makes each person unique. Therefore, it is difficult to make a generalized statement about perception besides the fact that it can drastically change the way identical events are interpreted. Perception can be influenced by many different factors such as culture, economic status, and religion. These factors can be described as filters through which the world is perceived. When applied to a knowledge claim, perception mainly varies between individualsââ¬â¢ views of what it means to know something. Take, for instance, the individual making the knowledge claim, ââ¬Å"I know this music. One personââ¬â¢s perception of what it means to know could vary from the perception of the person being told. The only way to bridge this gap in perception, is to become tolerant of othersââ¬â¢ views. Applied to others areas of knowledge, these ways of analyzing knowledge claims are valid yet sometimes irrelevant. For instance, the methods work for theoretical, language, and creativity based areas such as politics and the arts. However, when applied to more factual areas like mathematics and the natural sciences, the above methods are not suitable. For these areas, processes such as proofs and the scientific method are used. How to cite Evaluating Areas of Knowledge, Papers

The Link Between Cyber-Bullying and Suicide free essay sample
When people hear the word ââ¬Å"bullyâ⬠they often think of the tough guy in school who seems to push and shove his peers into lockers and take away their lunch money. The idea of this type of bully has become popular and many people today would consider it a means of toughening up and is also widely known as an inevitable part of growing up or a phase in a childââ¬â¢s life. Recently there has been a rise in a new form of bullying; cyber bullying. With the fast acting rise of technology and the expanding power and popularity of the internet thereââ¬â¢s a new bully in town and it exists in your childââ¬â¢s computer. This type of torment is extreme, causing young people to take their lives. Additionally to the adolescents who successfully take their life, many of them still attempt and continue to strongly think about suicide. We will write a custom essay sample on The Link Between Cyber-Bullying and Suicide or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Teenagers have easy access to dozens of social networking sites like Facebook, Twitter, and Tumblr, which allow other individuals to hide their true identity. Many of these websites have the option to make yourself anonymous where you can send any user a comment without them knowing who send it. It is also very easy for an individual to make a fake profile and attack other individuals that way. Individuals donââ¬â¢t always keep their identities a secret, many times groups of students target another student and send them harsh comments like ââ¬Å"go kill yourself alreadyâ⬠and ââ¬Å"the world would be better off without youâ⬠. Amanda Todd, a Vancouver-area teenager who posted a story to YouTube last month about being cyber-bullied, was found dead Wednesday night in Coquitlam, Canada. Authorities believe she committed suicide (Grenoble, Ryan). This 14 year old girl committed suicide on October, 11, 2012 due to cyber bullying. Previous to her death, Todd posted a video on YouTube telling her story with a series of flash cards. The torment began, according to Todds YouTube video, after she flashed a man onlinewhen she was in seventh grade. One year later, she said, he tracked her down onFacebook and forwarded her topless photo to everyone. She was bullied at each schoolshe went to, beat up by angry girls and attempted to kill herself by drinking bleach(Grenoble, Ryan). Even after Todd attempted to commit suicide by drinking bleach bullied still targeted her by writing things like ââ¬Å"you shouldââ¬â¢ve drank more bleachâ⬠on her Facebook wall. Individuals still continue to target her by posted negative comments on her R. I. P fan page. Another teenage girl who continues to receive negative comments even after her death is Phoebe Prince who committed suicide in 2010 at age 15. ââ¬Å"Girls at Phoebes school reportedly called her a wh**e and a bi**h, viciously harassing her in person and on Facebook. At least one student gloated after Phoebe took her own life, I dont care that shes dead. â⬠(Holladay, Jennifer)â⬠Cyberbullying has spread so quickly with the wide spread of internet. According to the 2009 AP-MTV Digital Abuse Study done by Janice Gatti, 50% of people age 14-24 have experienced digitally abusive behavior. Surprisingly enough we might be a cyber bully without even knowing. Many individuals post some negative comments on YouTube or Tumblr without even knowing or thinking about how the other person might feel but certain individuals do this regularly and these are the cyber bullies. Another suicide linked to cyber bullying is the death of 16 year old Jessica Laney. Laney being bullied on a website called ask. fm where users interact by asking each other questions is what caused her to commit suicide. Posts on Laneyââ¬â¢s page range from the innocent ââ¬â ââ¬Å"What class do you like the most? â⬠to the shockingly cruel ââ¬â ââ¬Å"Why are you so ugly? and ââ¬Å"Just kill yourself. Youââ¬â¢re worthlessâ⬠(Murray, Rheana). Close friends to Laney spoke about their friends death. ââ¬Å"You get compliments sometimes, but itââ¬â¢s those negative comments that bring youdown,â⬠close friend Cheyenne Ellsmore told local station. ââ¬Å"There are just things yous houldsay and things you shouldnââ¬â¢t,â⬠said another friend, Lisa Arthur. ââ¬Å"And on Ask. fm,none of that should be saidâ⬠(Murray Rheana). Laneyââ¬â¢s parents spoke briefly about their daughterââ¬â¢s death as well and mentioned that their daughter also had a history of mental health issues but the cyber bullying is what pushed her over the edge. It is impossible to ignore a cyber bully when all they want to do it attack you as an individual. We go on our social networking sites to enjoy and express ourselves not to have ourselves attacked by anonymous people or our classmates. According to the Cyber Bullying Research Center, Even though less than 10% of middle-school students reported being cyber bullied in the previous days, approximately 43% reported experiencing one of the several experiences that could be defined as cyber bullying. Among the most commonly experiences included: receiving and email that make them upset (18. %, not including spam), receiving an instant message that made them upset (15. 8%), and having something posted on their MySpace that made them upset (14. 1%). Everyone at one point receives at least one negative comment aimed towards us but these individuals who commit suicide over these cyber bullies are extremely targeted and are hit with something that may easily affect them or have been targeted fo r a long amount of time. Victims of cyber bullying who commit suicide have negative comments aimed at them daily. From their looks to how they are to what they do, comments involving any of these are not easily dealt with. An individual whose homosexuality was targeted by a cyber bully was Tyler Clementi, an 18 year old who committed suicide in 2010. His college roommate streamed a video live from their room while Clementi was with another boy. Just a day later, at 8:42 p. m. , Clementi posted this terse status update on Facebook: Jumping off the gw bridge. Sorryâ⬠(Nadine, Shabeeb). Homosexual individuals are a big target for cyber bullies. A 2005 Harris poll found 90 percent of gay and lesbian teens say theyve been bullied inthe past year. And nearly two-thirds of these students feel unsafe in school, according to a2009 survey by the Gay, Lesbian and Straight Education Network. In September alone,three other teens took their own lives after homophobic taunting (Nadine, Shabeeb). A second target to cyber bullies because of his homosexuality was Seth Wash, who committed suicide at age 13 in 2012. On Oct. 1, 600 people crammed the First Baptist Church in Tehachapi to remember SethWalsh, a 13-year-old who liked Pokemon, dance music and reading the Bibleand whohad (somewhat reluctantly) acknowledged to understanding family members and friendsthat he liked other boys. Seth had been teased relentlessly; it started when he was infourth grade, according to his grandmother Judy Walsh. By sixth grade, kids werestarting to get mean, she says. By seventh grade, he was afraid to walk home fromschoolâ⬠(Cloud, John) According to Gay Bullying Statistics, gay and lesbian teens are two to three times as more likely to commit suicide than other youths. About 30 percent of all completed suicides have been related to sexual identity crisis. Students who also fall into the ay, bisexual, lesbian or transgendered identity groups report being five times more likely to miss school because they feel unsafe after being cyber bullied due to their sexual orientation. About 28 percent out of those groups feel forced to drop out of school altogether. Although more and more schools are working to crack down problems with bullying, teens are still continuing to bully each other due to sexual orientation and other factors. Today only a few stated have laws against cyber bullying but there is more that needs to be done. Itââ¬â¢s not okay for people to attack other individuals online forcing them to commit suicide. Our laws are not keeping pace with technology, Klein said in an interview with CNN. No longer is bullying only confined to the schoolyard. It is now piped in an instant through victims computers and onto the devices they carry in their pockets. This legislation will help provide protections to those who need it, as well as send a strong message about the seriousness of this destructive behaviorâ⬠(Cyberbullying Crackdown). Parents and teenagers can help prevent cyber bulling. Parents can talk to their children advising them the negative and positive effects of writing about someone online. If you see your friend posting a comment on someoneââ¬â¢s social networking site, stop them, even if it looks like it can do no harm, it may cost a life. If you see a case of cyber bullying tell someone else, when you see something it might not seem so damaging but itââ¬â¢s after someone takes their life away when the regret starts to hit them and them itââ¬â¢s too late. If you are experiencing cyber bullying stay off your computer for a while, donââ¬â¢t go on your social networking sites because the more you read them the more it will affect you. Donââ¬â¢t take part in cyber bullying, you might think your just posting a few innocent comments but you are going to affect someone. There is definitely a connection between cyber bullying and suicide. Other factors like mental disorders can also increase the risk of suicide but in cyber bullying, one small push is enough to take someone over the edge. For example, a girl with major depression who might already have suicidal thoughts and is starting to become cyber bullied, being cyber bullied would be that push to commit suicide. Individuals sometimes arenââ¬â¢t aware that their words can cost a life. You might think that youââ¬â¢re just giving your opinion but to the other person those are harmful words, and after a life is taken apologies donââ¬â¢t bring the person back. A negative comment could mean the difference of one more life being taken away. Young teenagers need to be taught that saying things online can have huge consequences. Targeting some online means no escape for the victim. You might think that just because youââ¬â¢re not saying this one negative comment to an individual in person doesnââ¬â¢t mean itââ¬â¢s not going to affect them.

Love Song to a Dictionary
Love Song to a Dictionary Love Song to a Dictionary Love Song to a Dictionary By Maeve Maddox Most writers of English in every part of the world acknowledge the Oxford English Dictionary (OED) as a reliable reference to settle questions of spelling, pronunciation, and usage. Today computers are used to organize, store, and supplement the online Second Edition of the OED at the rate of 4,000 new words a year. But the OED had its beginnings long before computers made the lexicographers work easier. It took 120 keyboarders working six years to key in the more than 350,000,000 handset characters of the First Edition from which the Second Edition derives. The First Edition, compiled and printed the old-fashioned way, required numerous editors, thousands of volunteer readers, millions of slips of paper, and 70 years to achieve completion. But these are nothing but dry statistics. For a glimpse of the human side of the mighty OED, read Simon Winchesters The Professor and the Madman. Subtitled A Tale of Murder, Insanity, and the Making of the Oxford English Dictionary, Winchesters book is an instructive example of narrative nonfiction as well as a fascinating read. It tells the story of James Murray (the professor) and W.C. Minor (the madman). Murray took over the editorship of the OED in 1879 and remained at the job until his death in 1915. He guided the dictionary from A-T. Minor was a former American army doctor incarcerated from 1872-1910 in the Broadmoor hospital for the criminally insane. He contributed thousands of the quotations that illustrate usage in the OED entries. Minor killed an Englishman, but escaped execution by reason of insanity. Because of his personal wealth and usually mild behavior, he was given special privileges, such as having two rooms in a cell block with a pleasant view. He fitted one of the rooms as a library and collected old books. When Professor Murray sent out a call in 1879 for volunteers to contribute illustrative quotations to the OED, Minor responded. He applied himself to a systematic reading regimen and earned Murrays attention and respect. Winchesters embroideries and speculations are sometimes a little over the top. He waxes romantic as he commiserates with Minors victims and speculates on the possible causes of Minors mental condition. Overall, however, The Professor and the Madman is an excellent use of research to create a non-fiction book that is hard to put down. It casts a reference book we take for granted in a new light.

Can we identify a compound that could be added to spermatozoa in vitro Assignment
Can we identify a compound that could be added to spermatozoa in vitro to enhance their motility - Assignment Example In particular, sperm motility is an important parameter because it indicates the integrity of the sperm tail and axoneme structures as well as the status of mitochondrial metabolic machinery (Saharkhiz et al., 2013). The World Health Organization uses a 40% cut off as the lower limit of progressive sperm motility. Although the exact cause of asthenospermia is not clear, there is growing evidence that it may arise due to hyper-viscosity of semen, varicoceles, autoimmunity of the sperm cell, and necrospermia resulting from immotile cilia (Kartagener) syndrome (Saharkhiz et al., 2013). Overall, reduced sperm motility indicates epididymal or testicular failure that can be caused by various factors. Currently, treatment of male infertility has focused mainly on the traditional in vitro fertilization (IVF) approach and newer interventions such as micro-epididymal sperm aspirations and microsurgical fertilization. However, these techniques are uncommon in andrological practice. Current research efforts in this area focus on the use of chemical stimulation of spermatozoa. A number of chemicals can stimulate sperm motility including the addition of compounds known to exhibit phosphodiesterase inhibition (PDEI) activity to enhance sperm motility in vitro without compromising sperm morphology and function. PDEIs are a class of related compounds such as pentoxifylline (PTX) that selectively catalyze the hydrolysis of 3ââ¬â¢ phosphate bond in cyclic Adenosine Monophosphate (cAMP) phosphate or cyclic Guanosine Monophosphate (cGMP). In one of the pioneering studies on in vitro stimulation of sperm motility, Shen (1991) demonstrated that Pentoxifylline (PTX) increases motility (velocit y) of ejaculated human spermertozoa both in in vitro aesthenozoospermic samples in oral therapy. Related studies have shown that PTX added in sperm suspensions increases sperm motion within 10 days with the motility characteristics persisting

Before Sunset Essay Example | Topics and Well Written Essays - 1000 words
Before Sunset - Essay Example The movie has rightfully earned great critical acclaim for portraying the lives of two individuals, who love each other dearly but are always pulled apart because of their circumstances. Moreover, it was not just the plot of the story that was laudable but the premise of the film further entails several themes regarding the geographical and urban design of the contemporary society that has greatly isolated people and restricted interaction on a daily basis. Even in the past, films were tools that were used vastly as a means to promote a particular city or culture. The entire filming before sunrise was done in Paris, providing insight into how urban structure seems to have affected the lives of the masses. The film depicts the life of both the protagonists and the degree to which their lives had changed over the period of their separation. Both Jesse and Celine portray contemporary individuals, who experience the rising problems of an urban society; loneliness being one of the primary issues. This concept is called urban isolation, which arises as a result of the layout of our society that prevents social encounters and interactions. From architecture to the overall communication network, modern civilization has been developed in such a way to protect the privacy of individuals that besides making things easier for people often results in people becoming more and more distant from each other. As a matter of fact, from residential buildings to everyday travel, privacy and seclusion are marketed as an asset and this feature is being made more attractive that makes people want to achieve it. This aspect is ostensible in the movie through the segregation that is believed to have been prolonged because of this aspect of the society. From the first movie, both of them had been heading towards opposite directions, although their circumstances kept them from reaching out to each other, but the period of their separation was further
