A Brief History of Typing and Qwerty Keyboards

A Brief History of Typing and Qwerty Keyboards A typewriter is a small machine, either electric or manual, with type keys that produced characters one at a time on a piece of paper inserted around a roller. Typewriters have been largely replaced by personal computers and home printers. Christopher Sholes Christopher Sholes was an American mechanical engineer, born on February 14, 1819, in Mooresburg, Pennsylvania, and died on February 17, 1890, in Milwaukee, Wisconsin. He invented the first practical modern typewriter in 1866, with the financial and technical support of his business partners Samuel Soule and Carlos Glidden. Five years, dozens of experiments, and two patents later, Sholes and his associates produced an improved model similar to todays typewriters. QWERTY The Sholes typewriter had a type-bar system and the universal keyboard was the machines novelty, however, the keys jammed easily. To solve the jamming problem, another business associate, James Densmore, suggested splitting up keys for letters commonly used together to slow down typing. This became todays standard QWERTY keyboard. Remington Arms Company Christopher Sholes lacked the patience required to market a new product and decided to sell the rights to the typewriter to James Densmore. He, in turn, convinced Philo Remington (the rifle manufacturer) to market the device. The first Sholes Glidden Typewriter was offered for sale in 1874 but was not an instant success. A few years later, improvements made by Remington engineers gave the typewriter machine its market appeal and sales skyrocketed. Typewriter Trivia George K. Anderson of Memphis, Tennessee patented the typewriter ribbon on 9/14/1886.The first electric typewriter was the Blickensderfer.In 1944, IBM designs the first typewriter with proportional spacing.Pellegrine Tarri made an early typewriter that worked in 1801 and invented carbon paper in 1808.In 1829, William Austin Burt invents the typographer, a predecessor to the typewriter.Mark Twain enjoyed and made use of new inventions, he was the first author to submit a typewritten manuscript to his publisher.

Runway Incursion essays

Runway Incursion essays A runway incursion is any occurrence at an airport involving an aircraft, vehicle, person, or object on the ground that creates a collision hazard or results in a loss of separation, as defined by air traffic requirements. This separation loss can happen to a departing aircraft, or one preparing for a takeoff. Planes that are landing or intending to land can become subject to a loss of separation or incursion. In other words, ground operations are fertile ground for incursions. Although general aviation accidents have been decreasing over the past few years, incursions with all dangers attached to them have been increasing at an alarming rate. It is merely a matter of time for these incursions become tragic accidents. On 431 occasions in 2002, two aircraft or an aircraft and a vehicle mistakenly got too close together on an airport runway. Another mounting problem at U.S. Airports is delays. Currently the average airport delay per flight is eighteen minutes and by the year 2010 experts expect this number will climb to 44 minutes if no new technology is implemented at airports. The costs of these delays cost airlines over 254 million dollars per year which will lead to an increase in fares for passengers. The most logical way to reduce delays is to build more runways at the major airports but this will not solve the problem of runway incursions. The next step that many airports and the FAA have been researching, is installing new surface and navigation systems at airports. Two of the newest systems that have been researched are Airport Surface Detection Equipment Model X (ASDE-X) and Airport Movement Area Safety System (AMASS). This paper will focus on the technology behind ASDE-X and AMASS, benefits of these technologies, issues with these systems, cost/benefit analysis, strategies behind the use of these systems and finally how these technologies will change in the future. Continuous growth in US aviation is resulti...

Sexual imagery in the media Essay Example | Topics and Well Written Essays - 500 words

Sexual imagery in the media - Essay Example The sexuality-based images are depicting men as dominant, robust and aggressive individuals while women are portrayed as being meek and vulnerable. Psychologists argue that such a portrayal of both the sexes in the media has only distorted their beliefs and perceptions about themselves and has thus prevented them from realizing their inherent values and cultural practices (Casciani). The number of online sexuality-based games has hugely increased over the years with the 2010 estimate of the video gaming industry topping $20 billion and nearly $300 million spent every year on advertisements related to sexual activity. In addition to games, television reality programs such as The Bachelor and Temptation Island are conveying messages that are supportive of partnering and that such indulgence does not have any real consequences (Gilbert). Several commercials are using sexualized images of women to promote their products such as clothing which are mainly targeted at teenagers. Such imager y has resulted in a widespread notion that women are there to be used by men (Gilbert). Experts who had studied the sexual behavior of children found that they were largely influenced by sexual images shown in the media.

Evaluating Truth and Validity Exercise Essay Example | Topics and Well Written Essays - 1250 words

Evaluating Truth and Validity Exercise - Essay Example They even went to the extent of providing high scholars and college student’s credit cards. This trend has less to careless spending from this age group (Jain, 2009). Teenager and adolescents are usually irrational in their decisions. Coupled by peer pressure and the feeling of wanting to fit in, some of these young people end up spending without knowledge of how they are going to pay. It has become something which many should are worried since giving money to spend to such children that is unlimited is like giving them a bomb. According to Jain (2009), people under the age of 21 should not be given any credit cards for their impulsive nature of careless spending (Jain, 2009). Even if one can sit with them, they always act defiant to their elders, hence would be a waste of time teaching them on wise spending whereas they are in a stage of discovering the world. How else can one discover the world when he or she is left with credit card? According to psychologist, money is not something which people under the age of 21 should not be given at their will since they do not have enough responsibility to know the value and repercussions of overspending since they would not be paying for them (Jain, 2009). According to Farrow (2010), power is believed to be the root of all evil, as it makes them corrupt. Power is defined as being in a position to control others. According to the Bible, power is a God given thing given to man to be in control over his creations (Farrow, 2010). Other people do believe that power is the root cause of evil, is it really true? One may wonder from the statement and provide examples of quite a number of people who have been in power and not corrupt. It is always not a fact to link corruption to power. Corruption is a virtue with exists in specific people. Taking a few corrupt individuals and generalizing them as making power corrupt from my opinion is not true (Farrow, 2010). Can we say that since the Pope is in power,

Leon Battista Alberti Essay Example | Topics and Well Written Essays - 1500 words

Leon Battista Alberti - Essay Example During the times Alberti introduced the idea of linear perspective, many other people could write a treatise about the upcoming work of art (Peter, 2007). Fortunately, he was the only fully equipped to manage the work than anyone else in the time. He had the passion for art and device of words which most of his associatesneeded. He brought a familiarity and logical baggage to the task, which was essentially giving utterances to the rules covering his new art and convinced all clienteles and artists that the art was worth taking. Alberti’s thinking that his theory and other works of those times could be precised as knowledge comes from sensory insights (Alberti, 1966). The sensory perception used in comparison with others and in relation to human being to make conclusions (Honour & Fleming, 2002). The conclusions made, approved, and applied by use of mathematics. In his theory mostly made use of, joints of pyramids with image surface, comparativetrios and side view for foreshor tening while testing with diagonal and the use of street as locus. Alberti was concerned with filmicentrances since person’s knowledge relies on sensualfacts. The fact that most solid bodies have a skin, Alberti was also concerned with the play of shades through the surface of an entity. Once these observations are, made conclusionsusing comparison since with it there is a power that illustrates within entities that are less or equal (Martin, 2003). Alberti believed that, man, nature, and mathematics are parts of one thing and that man uses mathematics to comprehend and regulate nature. In his theory, mathematics is a solutions not an end as the theory is more of appearance that reality. As Alberti is concerned, mathematics used to control the data used in art and the painting by itself. In his theory, he advocates for fertility and diversity of color codesand presumes the same variety of man positions and engagements. He says that good work of art has to consist of all sorts of living things including human beings of all ages and both male and female. He has not set formulae to guide the artist, but has put the obligation for the result in the artist’s hands. His approach of the use and the easy way of changing three-dimension world into two-dimension has helped many artist in their work and has been adopted by many across the world (Alberti, 1966). Alberti claims that a point is symbol that cannot split into several parts because it can be located on a plane and visible. He further explains how points joined to form a line and how these lines joined in rows to make a plane. A plane is known by its length and breadth and if need be the quality. Some plane qualities cannot change without changing the plane while others are due to visual effects and seems to change to the viewer even as the plane remains unchanged. A plane changes its name and shape when either its angles or lines are changed. By making angles either more acute or obtuse and short ening or lengthening the lines will completely change the plane. Alberti further explains other qualities of a plane that lie on the surface of a plane. There are two other qualities according to Alberti which although seems to change the plane, it is not actually changed (Stockstad, 2004). This depends on the power of sight as explained above, when the distance between an object and the eye changes, the object seems to

Impacts Of Global Fuel Price Fluctuations Tourism Essay

Impacts Of Global Fuel Price Fluctuations Tourism Essay The fuel prices are determined by the crude oil prices. In order to produce fuel and other petroleum products, the main raw material used is crude oil. (Chevron Corp, N/A) The prices of crude oil are determined by the market force of demand and supply. If there are grows in demand or disruptions in supply of crude oil, then the market will adjust by increasing the price of crude oil, subjected to the changes in demand or supply. One of the most recognisable causes of fluctuation in fuel prices is disruptions in the supply of crude oil in the market. Political instability is one of the factors. Majority of oil producer countries are in the emerging regions, where disruptions in supply of crude oil always happened and affecting the price. (Chevron Corp, N/A) Besides, shortages of supply can be resulted from a sudden refinery outage or maintenance and pipeline problems. On the other hand, the rise in the price of crude oil is caused by the increase in international energy demand driven by strong long term economic growth especially in non-OECD countries. According to the U.S. Energy Information Administration, make a projection that in between 2006 to 2030, there will be a dramatic increase of 44% in the total world consumption of energy. (Caltex, N/A) Adding together political instability, disruptions in the supply and growing demand for crude oil cause the price of fuel to be volatile. (237w) To manage airlines companies, the management will try to minimise any cost associates with the company. According to Air Transport Association, 25.4% of airlines operating expenses were contributed by fuel. As the fuel price becoming increasingly volatile, airlines industries will face risk in rising fuel price and one of the ways to get rid of the risk is by hedging the fuel price. Hedging is a risk management tool that allows airlines to lock in a price for fuel and protect them from the risk of soaring fuel price in future. Neeraj Kapoor, Go Air spokesperson commented that aviation fuel pricing in certain region like India does not favour hedging, but recent hike in fuel price make them reconsider on hedging their fuel. (Kabtta, K, 2008) On the other hand, South West Airlines, which hedged about 70% of its fuel, got to consume it at a lower price of $51 a barrel, compared to the market price of $135 per barrel. (Kabtta, J, 2008) Besides hedging, airlines usually will increase the price of its fuel surcharge. Fuel levy or fuel surcharge is the additional cost to the fare, imposed on per ticket basis in order to retrieve the rising price of the fuel. (Koch, R, 2010) As for example, Virgin Blue had decided to follow Qantas action of increasing fuel surcharges due to the spike in global fuel prices. (Oà ¢Ã¢â€š ¬Ã¢â€ž ¢ Sullivan, M, 2011) In short, an airlines company could avoid the surge of global fuel prices by either hedge the fuel price with any hedging instrument such as options or increase the fuel surcharge on the passenger. (268 w) Now let us examined what are the possible impact that fuel price volatility may bring to the airlines industry and suggestion for the airlines company in dealing with this crisis. As we had discussed above, a surge in fuel prices will directly hit the airlines industry as the rising in cost of fuel will result in increase on the cost of operation. Besides, fuel prices are determined to have a relationship with economic recessions. Soaring fuel prices will trigger higher inflation which later be cooled off by monetary policy. As a result, demand for air travel will decline. Despite facing such challenge, there are airlines that determined enough to go against the tide by trying to reduce costs as well as implementing new strategies to be more competitive. Most of the airlines resorted in drastic action by firing some of their employee in order to cut cost since labour cost contributed almost 24.7% out of total operational cost. (Air Transport Association, N/A) As for example, due to s udden hike in fuel prices, Qantas determined to cut down the number of its employees. (Hannan, E, 2011) While other airlines company trying their best in finding new strategies in order to stay competitive with other airlines. For example United Airlines strategy is to use software developed for flight planning to choose the best route and speed of flight. (Wilen, J.2008) Another good example is Cathay Pacific where they decided to opt towards more fuel efficient aircraft such as Boeing 747-8F and Boeing 777-300ER other than issuing fuel surcharge on tickets to cover for soaring fuel prices. (Cathay Pacific Airways Limited 2010)In brief, increase in fuel prices may impact the airlines industry directly or indirectly and there are several ways to face this issue.(291) In summary, airline industry has been badly affected by the rising fuel prices. The industry is losing both customers and revenues. Some airlines are trying to go against the tide by reforming themselves, but to a limited success. These airlines are working hard to reduce cost and implement new strategies to win back customers. While the world is still in recession, those efforts have started to show some good results. As such, it is possible to see airlines will bounce back and recover from bad financial conditions sooner.(88)

Kimchi Journal :: China Chicken Virus Kimchi Essays

Kimchi Lifesaver Finals are finally over and I will be leaving for Korea in two days. I haven't been to Korea in nearly ten years but I still remember the savory foods vendors sell along the streets of Myong Dong Market. My grandmother called me today with some unfortunate news. She informed me about a bird flu called Avian Influenza that has infected poultry across the farms in South Korea. "You need not worry, sweetie," my grandmother said in Korean. Strict measures were taken so that farms would not further spread this disease. Nonetheless, grandmother told me to pack my warm clothes and prepare myself for some good Korean food. I can hardly wait. December 25, 2003 A kimchi Christmas. I have been eating kimchi like there is no tomorrow. Don't get me wrong, I love kimchi. However, I have been eating more than my stomach and breath can handle. Scientists from Seoul National University came out with a study a few days ago stating that a lactic enzyme in kimchi has remedial effects on chicken and other types of poultry. I assume kimchi's "antibacterial powers" have kept my family and I clean from this epidemic. With what I could understand from the Korean news, the bird flu is extremely infectious to organisms such as poultry. I went on the Center for Disease Control website to get a much more comprehendible version of the epidemic. It conveyed that the disease spreads rapidly from bird to bird as large amounts of the virus are secreted in bird droppings, contaminating earthly surroundings. The technical term for the disease is called Avian Influenza A H5N1. The big scare, The World Health Organization admits, is that this strain has the unique capacity to jump the species barrier, causing several diseases in humans. I will not be eating chicken for a while. January 5, 2004 I am finally back in the States. It is such a relief that we do not have to deal with Avian Influenza here. Although CDC said the risk of H51N flu in the United States is low, I cannot help but think that travelers such as myself could contract the virus and bring it back to infect others. This wouldn't happen to us though. January 13, 2004 Kimchi Journal :: China Chicken Virus Kimchi Essays Kimchi Lifesaver Finals are finally over and I will be leaving for Korea in two days.

Little Miss Sunshine

â€Å"By the end, all have achieved a deeper appreciation of the others, a deeper understanding of the value of family, a better life were love, solidarity and understanding replace hatred, sarcasm and anger. † Little Miss Sunshine (2006) directed by Jonathan Dayton and Valerie Faris, is an American road-comedy that shatters the mold. Incredibly satirical and ironic yet, is how deeply human as the Hover family is one of the most appealing in recent film history. The film has a fabulous beginning in which you meet each Hoover individually, pointing out their great differences, during their personal moments through a series of montage shots. Throughout the road trip the family suffers many personal setbacks and discovers the need for each other’s support. Olive is the youngest of the Hoover family and the central character of Little Miss Sunshine. The film begins with her standing in front of the television mimicking the beauty pageant winner. When she finds out she has qualified in the Little Miss Sunshine pageant she is ecstatic but her Uncle, Brother and Father are not too keen on going. Because Olive is the centre of the family they all agree that it they will go and support but choose not to have any fun. Richard puts a lot of pressure on Olive when they find out she’s in the final of the pageant. After listening to her dad talking about winning and losing all the time Olive is scared her dad won’t be proud of her like her Mother would be. Olive asks her Grandpa about the pageant and losing and Grandpa tells her â€Å"Losers are people who are so afraid of not winning, they don't even try†, he is not a big fan of Richards nine steps and gives his own definition of ‘Losers’. On the way to Florida they stop at a gas station and realize they have left Olive there so they quickly turn around but Olive is still standing there waiting and is not at all worried they have forgotten her because she is the whole reason they are going. A big moment in the movie would be when there symbolic, yellow Volkswagen breaks down and they all have to push to get it started; for once they are all working together and become happier. Despite everything that happens with the Hoover family, the biggest change in Olive throughout the whole movie would be that she finally accepts herself for who she is and doesn’t care what people think of her. Richard is the father of Olive and stepfather of Dwayne. A45 year old motivational speaker, he wears pleated pants, a golf shirt and sneakers. Richard can’t cope with losers, and with his nine steps to success that’s all he talks about at home. You can tell by the old technology he uses that his nine steps are not very successful; at this point he is not a winner but has strong belief. When the family finds out Olive got into the finals of little miss sunshine Richard tries to talk them out of going because he could have a big break in his nine steps. When Sheryl tells Richard Frank is staying with them he doesn’t really care and asks about Stan Grossman calling in case he liked his proposal. Frank asks about Dwayne’s vow of silence Richard of course, goes on about his nine steps and the whole family is sick of it and tries to shut him off. Sheryl is set on taking Olive to Florida but Richard is being selfish and only cares about if Stan Grossman likes his ‘nine steps’. When Sheryl finally convinces him to go he puts a lot of pressure on Olive about winning. I think Richard changes the most in Little Miss Sunshine as at the start of the movie he only cares about himself and his nine steps but throughout the movie and when he loses his father he begins to accept his family and doesn’t care about his â€Å"big break†. At the pageant he doesn’t want Olive to go on stage because he is afraid people will make fun of her and he really starts to care. Dwayne is first seen at the start of the movie lifting weights, doing push ups and sit up. You then see him put a big cross on his calendar, by this you can see he has set a goal but not quite sure what it is yet. When the whole family is home, you notice Dwayne doesn’t talk and writes everything on a notepad. When Frank asks him about having any friends he writes on his notepad: â€Å"I hate everyone† Frank finds it weird and asks about his family, he then rolls his eyes and underlines everyone. Dwayne can not put up with Richards nine steps and when Frank asks him about his goal Richard butts in and is making it all about him. When Dwayne finds out he is colour blind during the trip he gets really agitated in the car and starts hitting his head against the wall, they final stop the car and he lets out a big scream. When Sheryl goes to try and make him feel better he just says he hates his family and wants to be left alone. They agree that they cant do much else except wait for him to calm down, when Olive goes down she just leans her head on his shoulder and I guess he realises he is being kind of selfish and for the first time in the whole movie you hear Dwayne speak and apoligises to the family. While at the beauty pageant Dwayne starts to really care for Olive and tells Sheryl not to let her on the stage otherwise everyone will make fun of her but even though one judge is shocked with Olive’s dance the rest of the family don’t care and go up and join her. Dwayne changes dramatically in the movie. Going from someone who didn’t talk, was very selfish and hated everyone to now really caring for his family, talking and overall a changed person. There are heaps of different film techniques used in Little Miss Sunshine for instance, when Dwayne tries the colour test the music goes from happy music to the music where you know something bad is going to happen and that’s when you find out Dwayne is colour blind. The opening and closing scenes are completely opposite to one another. The effect it would have on the audience would be significant, like even a dysfunctional family like the Hoovers can get through tough times, anyone can. In conclusion the movie Little Miss Sunshine was very well filmed, it had a big effect on the audience and the actors worked really well.

How does Shrek Undermine the Traditions of a ... essays

How does Shrek Undermine the Traditions of a ... essays How does Shrek Undermine the Traditions of a Stereotypical Fairy Tale through contrasting the characters Shrek and Lord Farquaad? Shrek is undeniably an intelligent film that uses many devices to undermine the traditions of a stereotypical fairy tale. One of these devices is characterisation. As the main character and the hero, many of these devices are centred on Shrek an ogre. Farquaad should be the hero figure of the story, since he is the only male figure of nobility in the plot. As Shreks antithesis, however, he is the villain and therefore also has a great many unexpected aspects to him. Although there are many more things in the film that could have been analysed to show just how intelligent and wide ranging the subversion of the fairy tale genre was in the film, by analysing the important contrast between Shrek and Farquaad, it will be possible to provide an in depth explanation of one of the ways in which the makers of Shrek have subverted the stereotypical fairy tale. As with many Disney type fairy tale films, Shrek begins with the close up shot of a leather-bound book. It opens, as if by magic and an as yet anonymous character reads it. It is a fairy tale story about a beautiful princess held captive by a fire-breathing dragon in a tower. She waits for her true love to come and rescue her. The traditions of a stereotypical fairy tale are subverted immediately when the character suddenly declares What a loada.... The sound of a page ripping can be heard, then the flushing of a toilet. Shrek then comes out of an outhouse. It is clear that he has used the ripped page from the book in his ablutions. The fact that the title character indeed the hero of the film feels such contempt for the fairy tale genre emphasises the unusual take the film has on such traditions. It is also important that this is made clear from the very beginnin...

A Brief History of Prosthetics

A Brief History of Prosthetics The history of prosthetics and amputation surgery begins at the very dawning of human medicine. In the three great western civilizations of Egypt, Greece and Rome, the first true rehabilitation aids recognized as prostheses were made. Early use of prosthetics goes back to at least the fifth Egyptian Dynasty that reigned between 2750 to 2625 B.C. The oldest known splint was unearthed by archaeologists from that period. But the earliest known written reference to an artificial limb was made around 500 B.C. During the time, Herodotus wrote of a prisoner who escaped from his chains by cutting off his foot, which he later replaced with a wooden substitute. An artificial limb dating from 300 B.C., was a copper and wood leg that was unearthed at Capri, Italy in 1858. In 1529, French surgeon  Ambroise Pare  (1510-1590) introduced amputation as a lifesaving measure in medicine. Soon after, Pare started developing prosthetic limbs in a scientific manner. And in 1863, Dubois L Parmelee of New York City made a significant improvement to the attachment of artificial limbs by fastening a body socket to the limb with atmospheric pressure. While he was not the first person to do so, he was the first to make it practical enough to be used in medical practices. In 1898, a doctor named Vanghetti came up with an artificial limb that could move through muscle contraction. It wasn’t until the middle of the 20th century that major advancements were made in the attachment of lower limbs. In 1945, the National Academy of Sciences established the Artificial Limb Program as a way to improve the quality of life of World War II veterans who suffered the lost of limbs in combat. A year later, researchers at the University of California at Berkeley developed a suction sock for the above-knee prosthesis. Fast forward to 1975 and  the year an inventor named Ysidro M. Martinez took things a major step further by creating a below-the-knee prosthesis that avoided some of the problems associated with conventional artificial limbs. Instead of replicating the natural limb with articulated joints in the ankle or foot which tended to lead to poor gait, Martinez, an amputee himself, took a theoretical approach in his design. His prosthesis relies on a high center of mass and is light in weight to facilitate acceleration and deceleration and reduce friction. The foot is also considerably shorter to control acceleration forces, further reducing the friction and pressure. New advances to keep an eye involve the growing use of 3-D printing, which has allowed for the fast, precise manufacturing of artificial limbs that traditionally have been custom-built by hand. The U.S. government’s National Institutes of Health has recently established the 3D Print Exchange program as a way to provide researchers and students with the necessary modeling and software tools to fabricate prosthetics using 3D printing machines.   But beyond prosthetic limbs, here’s another fun fact: Pare could also have laid claim to be the father of facial prosthetics, making artificial eyes from enameled gold, silver, porcelain and glass. Thats your fun fact of the day

Amanda Knox Court Case Essay Example | Topics and Well Written Essays - 2500 words

Amanda Knox Court Case - Essay Example Following four days and nights of interrogation, Amanda implicated herself and her employer at a bar in disputed circumstances. The police then arrested Amanda, Sollecito, and her employer Mr. Lumumba, although the later was released after Rudy Guede, an Ivorian raised in Perugia, was implicated by forensic evidence (Follain 12). Guede was convicted of the murder and sexual assault of Kercher and sent to prison. Sollecito and Amanda were found guilty during the first stage of the trial process and sentenced to 25 and 26 years in jail respectively. However, the second level of their trial saw them acquitted. The Background of Amanda Marie Knox Amanda Knox was born to Curt Knox and Edda Mellas in Seattle on July 9th, 1987. However, her parents divorced when she was still a baby. She grew up playing soccer in a bourgeois neighborhood where she earned the nickname Foxy Knoxy due to her athletic skills, a nickname that haunted her during the trial (Knox 25). Her relatives later described her as someone who did not have the full ability to pick up diverse social cues. While at school, Amanda took up an interest in the culture of the Italians and visited Italy as a fifteen-year-old together with her family. While on this trip, she decided that she would like to study there. She preferred a city such as Perugia that would allow her to meet real Italians, rather than Rome where she would mix with American expatriates (Knox 26). However, her stepfather discouraged her from moving there because he still considered her too naive. On graduating in 2005 from Seattle Preparatory High School, Amanda joined Washington University for a Linguistics Degree. As a college student, Amanda was named on the Dean’s list and was an ordinary college student with friends recalling that she was a gentle and kind individual. In the continuation of her â€Å"go-getter† attitude, Amanda decided to further her Linguistics Degree by heading for Perugia in Italy, where she was to sp end twelve months at the Foreigners University (27). On getting to Perugia, she met 21-year-old student Meredith Kercher from the UK, who also studied linguistics and roomed with her. Meredith had joined the University of Foreigners where she was to study Creative Writing, German, and Italian (27). According to media reports, while Amanda Knox was to most people a young and confident woman, her family and friends felt that she was a compulsive diarist, especially since she was averse to all types of conflict. These traits, which she showed during her time in high school and Washington University, including yoga practice at inappropriate times and her open and bubbly personality, were to have an effect on the trial. These traits made her more conservative, and reticent room and apartment mates viewed her critically while also causing the Italian police and prosecutor to be suspicious of her. The Murder of Meredith Susanna Cara Kercher Meredith Kercher was a UK citizen born in 1985 in South London’s area of Southwark. On joining the University of Foreigners, Kercher checked into a ground floor apartment with four bedrooms at Via della Pergola. This house was thought of as locals to be in a bad neighborhood, although most liked it for its panoramic view of Perugia. Her apartment mates included Amanda Knox and two other women. Meredith Kercher’
